This wheel lock device has a pair of locking arms installed so as to face each other around a receiving groove for receiving a front wheel of a two-wheeled vehicle. The pair of locking arms converts the rotation of the motor into a linear motion by a connecting link having a drive pinion and rack teeth, and swings by this linear motion. And in the state which the wheel lock piece provided in the one end side end of a pair of locking arm protruded, the ratchet arm and ratchet piece of a locking arm locking means mesh | engaged, and the wheel is locked.

JP 2001-001966 A (Detailed description of the invention, drawings)

  As described above, in this conventional wheel lock device, the pair of locking arms can be driven by the driving force of the motor to lock the wheels. However, in this wheel lock device, the rotation of the motor is converted into a linear motion by a connecting link having a drive pinion and rack teeth, and the pair of locking arms is swung by this linear motion. Therefore, in the conventional wheel lock device, it is necessary to use a complicated motor capable of controlling the rotation direction capable of forward and reverse rotation as the motor.

  Moreover, in the conventional wheel lock device, in addition to such a complex motor capable of forward and reverse rotation, a solenoid for releasing the meshing relationship between the ratchet piece and the ratchet arm is used to control the lock of the pair of locking arms. is necessary.

  Further, in the conventional wheel lock device, even if the meshing relationship between the ratchet piece and the ratchet arm is released by the solenoid, the pair of locking arms cannot be opened unless the motor is rotated in the reverse direction. For this reason, in the conventional wheel lock device, it is not possible to pull out a bicycle or the like parked only by solving the meshing relationship between the ratchet piece and the ratchet arm with a solenoid. Further, in the case where such reverse rotation control of the motor is not performed, in the conventional wheel lock device, the pair of locking arms are maintained in a closed state even though the lock is unlocked. It is necessary to move and open a pair of locking arms by hand.

  The present invention has been made in view of the above problems, and provides a wheel lock device, a parking system, and a driving method for a parking lock drive mechanism that can open and close a drive lock arm using a simple motor. The purpose is to provide.

  A wheel lock device according to the present invention includes a drive lock arm that locks a wheel, an eccentric link plate that can rotate together with the drive lock arm, a motor that rotates an output shaft when energized, an eccentric cam that rotates together with the output shaft, and an eccentricity. A long hole formed in the link plate and into which the eccentric cam is inserted.

  If this configuration is adopted, the eccentric cam is rotated by the rotation of the output shaft of the motor, the eccentric link plate into which the eccentric cam is inserted is swung by the displacement accompanying the rotation of the eccentric cam, and the drive lock arm is moved together with the eccentric link plate. It can be swung. Therefore, the drive lock arm can be opened and closed using a simple motor capable of rotating the output shaft in one direction by energization.

  In addition to the configuration of the invention described above, the wheel lock device according to the present invention includes a closed position detection sensor that detects a state where the wheel is locked by the drive lock arm based on the position of the eccentric link plate, and a drive lock arm. An open position detection sensor that detects the open state based on the position of the eccentric link plate, and the motor is deenergized based on the detection of the eccentric link plate by the closed position detection sensor or the closed position detection sensor. Is.

  If this configuration is adopted, a simple motor that can rotate the output shaft in one direction by energization is used to lock the wheel with the drive lock arm and open the drive lock arm. Can be controlled. Moreover, since the drive lock arm is locked by opening and closing only by rotation of the motor, it is possible to easily determine whether or not the wheel is locked by visually checking the open / close state of the drive lock arm. it can.

  The wheel lock device according to the present invention is, in addition to the configuration of each of the inventions described above, in the state where the eccentric cam is in contact with the eccentric link plate at the cylindrical outer peripheral portion and the wheel is locked by the drive lock arm. The position where the link plate and the eccentric cam are in contact with each other, the center of the outer peripheral portion of the eccentric cam, and the rotation center of the eccentric cam are positioned on a substantially straight line.

  If this structure is adopted, when the drive lock arm is opened in a state where the wheels are locked by the drive lock arm, the force that the eccentric link plate acts on the eccentric cam by this opening force is almost the contact point thereof. Force from the direction toward the rotation center of the eccentric cam. In addition, the tangent line of the eccentric cam at the portion where the eccentric link plate is in contact with the direction of the force that the eccentric link plate acts on the eccentric cam by this opening force is substantially perpendicular. Therefore, the force that the eccentric link plate exerts on the eccentric cam by the force to open the drive lock arm hardly generates a component in the direction in which the eccentric cam rotates (tangential direction at the contact point of the eccentric cam). As a result, even if an attempt is made to open the drive lock arm while the wheels are locked by the drive lock arm, the eccentric cam is difficult to rotate due to the opening force, so that the wheel lock state by the drive lock arm can be maintained. it can.

  The wheel lock device according to the present invention includes a reduction unit that decelerates the rotational speed of the eccentric cam lower than the rotational speed of the output shaft between the output shaft and the eccentric cam, in addition to the configuration of each invention described above. Is provided.

  If this structure is employ | adopted, the force which rotates an eccentric cam will be reduced by the deceleration unit, and will act on the output shaft of a motor. Therefore, even if a small motor having a light output shaft is used, the output shaft of the motor is heavy and the eccentric cam is difficult to rotate. As a result, even if a small and low output motor is used, the wheel lock state by the drive lock arm can be maintained.

  The wheel lock device according to the present invention includes, in addition to the configurations of the above-described inventions, a substantially rectangular housing, a shaft rotatably supported on the side surface of the housing, and a drive lock arm disposed outside the housing.

  If this configuration is adopted, the driven lock arm can be swung together with the drive lock arm. Further, the driven lock arm swings in the reverse direction to the drive lock arm. As a result, it is possible to ensure an opening angle that is approximately twice that of a case where only the drive lock arm is swung and opened. In other words, for example, even if the diameter of the eccentric cam is reduced and the angle at which the drive lock arm is swung is halved, the same opening angle as that when the drive lock arm is swung open can be secured. Thereby, a wheel locking device can be made small and light.

  The wheel lock device according to the present invention includes, in addition to the configurations of the above-described inventions, a substantially rectangular housing, a shaft rotatably supported on the side surface of the housing, and a drive lock arm disposed outside the housing. And a drive shaft on which an eccentric link plate is disposed in the housing, and a detection shaft that is rotatably supported on the side surface of the housing in parallel with the drive shaft and rotated by the wheel of the parked vehicle. The driven lock arm is pivotally supported on the detection shaft.

  If this structure is employ | adopted, a driven lock arm can be rotatably arrange | positioned facing a drive lock arm outside a housing using the detection shaft rotated by the wheel of the parked vehicle. In addition, the drive shaft and the detection shaft are pivotally supported on the side surface of the housing, and the motor, the eccentric cam, the eccentric link plate, etc. are disposed in the housing, and the motor, the eccentric cam, the eccentric link plate, etc. It is possible to provide a dustproof and waterproof structure that is difficult to get wet or collect dust.

  In the wheel lock device according to the present invention, the drive lock arm and the driven lock arm are formed of an engineering plastic such as polycarbonate resin in addition to the configuration of each invention described above.

  If this configuration is adopted, even if the locked wheel and the drive lock arm and the driven lock arm hit each other, the wheel is hardly damaged.

  The wheel lock device according to the present invention includes, in addition to the configurations of the above-described inventions, a pedal pushed down by a parked wheel, a detection plate that is displaced when the pedal is pushed down, and a detection plate in a state where the pedal is pushed down. And a urging member that urges a force in a direction in which the detection plate moves away from the parking detection sensor.

  If this configuration is adopted, it can be detected by the parking detection sensor that the pedal is depressed, that is, that the vehicle wheel is in the correct position. And a motor can be controlled based on the detection signal of this parking detection sensor, and a wheel can be locked.

  The wheel lock device according to the present invention is, in addition to the configuration of each of the above-described inventions, supported by a substantially rectangular housing and a side surface of the housing so as to be rotatable, and a detection plate is disposed in the housing. A detection shaft, and a pedal push-up lever that is rotatably disposed around the detection shaft outside the housing and pushes up the pedal in accordance with the urging force of the urging member.

  The vehicle locking device 3 includes a housing 41 that is fixed to the rear surfaces of the wheel rails 21 and 31. The housing 41 is formed in a box shape without a bottom while the upper surface is closed. That is, the housing 41 includes a substantially rectangular upper surface portion 41a, four side surface portions 41b to 41e provided along the periphery of the upper surface portion 41a, and an opening portion 41f formed at a portion that becomes the bottom surface of the box. It is formed in the shape to have. Such a housing 41 can be formed by bending a resin molded product (plastic), stainless steel, or other steel plate. An upper surface portion 41 a of the housing 41 is fixed to the rear surfaces of the wheel rails 21 and 31.

  A bottom plate 42 is fitted into the opening 41 f of the housing 41. By fitting the bottom plate 42 into the opening 41 f of the housing 41, the inside of the housing 41 is sealed. Therefore, a water-resistant structure in which water such as rain does not easily enter the housing 41 can be obtained. Note that an O-ring may be sandwiched between the four side surface portions 41b to 41e of the housing 41 and the bottom plate 42, thereby further preventing water from entering.

  Hereinafter, of the four side surface portions provided along the periphery of the upper surface portion 41a of the housing 41, the surface which is the front end side of the wheel rails 21 and 31 in the posture attached to the wheel rails 21 and 31 will be referred to as a front surface portion 41b. Then, the surface that is the rear end side of the wheel rails 21 and 31 is described as a back surface portion 41c, and the surface that is on the right side when viewed from the front end side of the wheel rails 21 and 31 is described as the right side surface portion 41d. A surface on the left side when viewed from the front end side is referred to as a left side surface portion 41e.

  Two circular through holes 43 and 44 are formed in the front portion 41 b of the housing 41. The two through holes 43 and 44 are formed side by side so as to be substantially parallel to the surface of the upper surface portion 41a near the upper surface portion 41a of the front surface portion 41b.

  A flange 45 is fixed to the front portion 41 b of the housing 41. The flange 45 is fixed to the front part 41b at a position closer to the opening 41f than the two through holes 43 and 44. The flange 45 includes a rear end side portion 45a formed by bending a substantially rectangular steel plate into a substantially vertical cross section, a horizontal portion 45b bent perpendicularly to the rear end side portion 45a, and the horizontal portion. It has a front end side portion 45c that is formed by being bent vertically upward on the front end side of 45b and is parallel to the rear end side portion 45a. Then, the rear end side portion 45 a of the flange 45 having a substantially bowl-shaped cross section is fixed to the front portion 41 b of the housing 41. Two circular through holes 46 and 47 are formed in the front end side portion 45 c of the flange 45 having a substantially bowl-shaped cross section. The two through holes 46 and 47 are substantially coaxial with the two through holes 43 and 44 formed in the front portion 41b of the housing 41 in a state where the flange 45 is fixed to the housing 41 (two through holes). (Positions overlapping each of the holes 43 and 44 in the horizontal direction).

  The drive shaft 51 is inserted into the two through holes 43 and the through holes 46 that are formed near the left side surface portion 41e of the housing 41 in the four through holes 43, 44, 46, and 47. The drive shaft 51 is formed in a cylindrical shape whose outer diameter is slightly smaller than the inner diameters of the two through holes 43 and 46 near the left side surface portion 41e. Therefore, the drive shaft 51 is rotatably supported by the housing 41 and the flange 45.

  The detection shaft 52 is inserted into the two through holes 44 and the through hole 47 formed near the right side surface portion 41 d of the housing 41 in the four through holes 43, 44, 46 and 47. The detection shaft 52 is formed in a cylindrical shape whose outer diameter is slightly smaller than the inner diameters of the two through holes 44 and 47 near the right side surface portion 41d. Therefore, the detection shaft 52 is rotatably supported by the housing 41 and the flange 45.

  A drive lock arm 53 and a driven lock arm 54 are disposed between the front end side portion 45 c of the flange 45 and the front portion 41 b of the housing 41. The drive lock arm 53 and the driven lock arm 54 are arranged and used in pairs. The drive lock arm 53 and the driven lock arm 54 are each formed in a substantially half-ring shape (hereinafter referred to as a semi-annular shape). When the drive lock arm 53 and the driven lock arm 54 are opposed to each other and both ends thereof are brought into contact with each other, a substantially annular ring is formed. The drive lock arm 53 and the driven lock arm 54 are made of polycarbonate resin. Polycarbonate resin is a kind of engineering plastic and has a characteristic that it is not easily damaged even when a large force is applied. In addition, engineering plastics such as polycarbonate resin have a feature that the material is softer than metal, so that it is difficult to damage the bicycle even if it hits the bicycle. For this reason, engineering plastics other than polycarbonate resin or other hard resin materials may be employed for the lock arms 53 and 54.

  The drive lock arm 53 has a through hole 53a formed at one end of the semi-annular shape, and the drive shaft 51 is inserted and fixed in the through hole 53a. The drive lock arm 53 rotates integrally with the drive shaft 51 around the drive shaft 51. The driven lock arm 54 has a through hole 54a formed at one end of the semi-annular shape, and the detection shaft 52 is inserted into the through hole 54a. The driven lock arm 54 is rotatable around the detection shaft 52 around the detection shaft 52.

  An engaging portion 55 is formed at the center of one end of the drive lock arm 53, and an engaging portion 56 is formed at the center of one end of the driven lock arm 54. The engaging portion 55 is formed with a convex portion 55a and a concave portion 55b. The engaging portion 56 of the driven lock arm 54 is formed with a concave portion 56a and a convex portion 56b. The distance between the two through holes 43 and 44 formed in the front portion 41b of the housing 41 and the distance between the two through holes 46 and 47 formed in the front end side portion 45c of the flange 45 are both drive shafts. 51, the distance between the engagement portion 55 of the drive lock arm 53 and the engagement portion 56 of the driven lock arm 54 in the state where the drive lock arm 53 is fixed to 51 and the driven lock arm 54 is inserted. Is formed. That is, the convex portion 55a of the drive lock arm 53 is fitted into the concave portion 56a of the driven lock arm 54, and the convex portion 56b of the driven lock arm 54 is fitted into the concave portion 55b of the drive lock arm 53. Functions as a link mechanism. In this embodiment, both lock arms 53 and 54 have exactly the same shape. For this reason, the outer diameter of the detection shaft 52 is slightly smaller than the outer diameter of the drive shaft 51.

  When the drive lock arm 53 rotates counterclockwise (counterclockwise in FIG. 4A) together with the drive shaft 51 by the above-described link mechanism, the driven lock arm 54 rotates clockwise (clockwise in FIG. 4A). To do. As a result, the drive lock arm 53 and the driven lock arm 54 are in a state where their other ends are spaced apart and opened. When the drive lock arm 53 rotates clockwise with the drive shaft 51 (clockwise in FIG. 4A), the driven lock arm 54 rotates counterclockwise (counterclockwise in FIG. 4A). . As a result, the drive lock arm 53 and the driven lock arm 54 are in a state in which their other ends are in contact or close to each other and closed. At this time, since the contact between the one end of the drive lock arm 53 and the one end of the driven lock arm 54 continues, the above-described substantially annular ring is formed.

  An eccentric link plate 61 is fixed to the end of the drive shaft 51 in the housing 41. A drive unit including a motor 62, a speed reduction unit 63, and an eccentric cam 64 is disposed inside the housing 41. The drive unit is fixed to the chassis 102. The chassis 102 on the upper surface side that is a part of the chassis 102 is disposed along the upper surface portion 41 a of the housing 41, and two side surfaces of the chassis 102 are screwed to the left and right side surface portions 41 d and 41 e of the housing 41. .

  The motor 62 includes a cylindrical motor housing 62a, an output shaft 62b rotatably supported on the motor housing 62a, a rotor (not shown) fixed to the output shaft 62b, and a space between the rotor and the motor housing 62a. And a stator (not shown) disposed in the. When a magnetic field is generated in the stator by energization, the rotor and the output shaft 62b rotate due to the magnetic attractive force or repulsive force between the stator magnetic field and the rotor magnetic field. When energization is lost, the rotation of the rotor and output shaft 62b stops.

  The reduction unit 63 has a gear group (not shown) in the unit case 63a and a reduction output shaft 63b. The gear group includes a plurality of gears, and includes at least a gear that rotates together with the output shaft 62b of the motor 62 and a gear that rotates together with the reduction output shaft 63b. And the deceleration rate by this deceleration unit 63 should just be about 1/1000-1/50. For example, when the deceleration rate is 1/100, the output shaft 62b of the motor 62 rotates 100 times, so that the deceleration output shaft 63b rotates once. In addition, it can replace with a gear group and can make it obtain a desired deceleration rate with the pulley group comprised by a some pulley. However, when a pulley is used, it is preferable to use a gear group because slippage is inevitably generated between the pulley and the belt spanning the pulley.

  The eccentric cam 64 has a disc-shaped cam body 64a and a through hole 64b formed in the cam body 64a. The central axis of the through-hole 64b is at a position deviated from the central axis 64c of the cam body 64a. Further, the deceleration output shaft 63b of the deceleration unit 63 is inserted into the through hole 64b. The eccentric cam 64 rotates integrally with the deceleration output shaft 63b.

  When the deceleration output shaft 63b rotates, the eccentric cam 64 rotates about the through hole 64b. Further, with this rotation, the eccentric cam 64 moves in a plane perpendicular to the central axis of the through hole 64b. This moving range of the eccentric cam 64 is determined by the distance between the central axis of the through hole 64b and the central axis 64c of the cam body 64a. The larger the distance between these central axes, the wider the moving range.

  The eccentric link plate 61 includes a link plate main body 61a having a substantially rectangular plate shape, a long hole 61b formed in the link plate main body 61a, and a sensor protrusion provided at the end opposite to the drive shaft 51. A portion 61c and a through hole 61d for inserting and fixing the drive shaft 51 are provided. The link plate main body 61a is fixed to the drive shaft 51 in a through hole 61d at one end in the longitudinal direction. The long hole 61b is formed in a shape in which the long direction is along the long direction of the link plate main body 61a. The front end of the sensor projection 61c is bent toward the motor 62, and the front end is detected by sensors 65 and 66 described later.

  In the drive unit, the cam body 64a of the eccentric cam 64 is inserted into the long hole 61b of the eccentric link plate 61, and the central axis of the through hole 64b of the eccentric cam 64 and the central axis of the drive shaft 51 are substantially parallel. It is being fixed to the housing 41 so that it may become. As a result, when the eccentric cam 64 rotates around the through hole 64b, the eccentric link plate 61 moves along with the drive shaft 51 around the drive shaft 51 within a predetermined angular range as the eccentric cam 64 moves. Swing with.

  Note that the angular range of the swing of the eccentric link plate 61 is determined according to the size of the eccentric cam 64 and the like. That is, the greater the distance between the central axis of the through hole 64b in the eccentric cam 64 and the central axis 64c of the cam body 64a, the wider the angular range of oscillation of the eccentric link plate 61.

  Further, the drive unit has a housing so that when the eccentric cam 64 moves within a predetermined range, the other end of the drive lock arm 53 and the other end of the driven lock arm 54 are in contact with or close to each other at least in one place. 41 is fixed. In this embodiment, in the state shown in FIG. 5 (A), both lock arms 53 and 54 are in contact or close to each other, that is, both lock arms 53 and 54 are closed. As shown in FIG. 5 (B), when the eccentric cam 64 is rotated approximately 180 degrees from the state shown in FIG. 5 (A), the two lock arms 53 and 54 are farthest apart, that is, the two lock arms 53 and 54 are It will be in an open state. Accordingly, the drive lock arm 53 and the driven lock arm 54 can be opened or closed by rotating the motor 62 of the drive unit by energization. It should be noted that the other end of the drive lock arm 53 and the other end of the driven lock arm 54 do not have to be in strict contact with each other when they are most closed. The distance between the other end of the drive lock arm 53 and the other end of the driven lock arm 54 when it is most closed may be narrower than the width of the bicycle wheel.

  In the housing 41, a closed position detection sensor 65 and an open position detection sensor 66 are disposed together with the sensor substrate 101. The sensor substrate 101 is fixed to the chassis 102. As the closed position detection sensor 65 and the open position detection sensor 66, an optical sensor that optically detects the position of the eccentric link plate 61 may be used. The optical sensor has a light emitting element and a light receiving element, and is a sensor that detects a change in a light receiving state in the light receiving element of light from the light emitting element. In addition, there are two types of optical sensors, a reflective type and a transmissive type, depending on the relative positions of the light emitting element and the light receiving element.

  For example, when a transmissive optical sensor is used as the closed position detection sensor 65, the sensor for the eccentric link plate 61 in a state where the other end of the drive lock arm 53 and the other end of the driven lock arm 54 are in contact with or in proximity to each other. The closed position detection sensor 65 is arranged so that the protrusion 61c is positioned between the light emitting element and the light receiving element of the closed position detection sensor 65. It should be noted that the sensor protrusion 61c in a state where the other end of the drive lock arm 53 and the other end of the driven lock arm 54 are separated is not positioned between the light emitting element and the light receiving element of the closed position detection sensor 65. There is a need to. The closed position detection sensor 65 outputs a detection signal when the light receiving element stops receiving light.

  When a transmission type optical sensor is used as the open position detection sensor 66, the sensor protrusion 61c of the eccentric link plate 61 in a state where the other end of the drive lock arm 53 and the other end of the driven lock arm 54 are farthest from each other. The open position detection sensor 66 is arranged so that is positioned between the light emitting element and the light receiving element of the open position detection sensor 66. The open position is detected at a position where the eccentric link plate 61 is not positioned between the light emitting element and the light receiving element when the other end of the drive lock arm 53 and the other end of the driven lock arm 54 are not farthest apart. It is necessary to install the sensor 66. The open position detection sensor 66 outputs a detection signal when the light receiving element stops receiving light.

  A through hole 52 a is formed at the tip of the detection shaft 52 that protrudes from the flange 45. The through hole 52 a is formed in a direction substantially perpendicular to the central axis of the detection shaft 52. A pedal push-up lever 71 is inserted into the through hole 52a. The pedal push-up lever 71 is formed in a cylindrical shape. Accordingly, when the detection shaft 52 rotates, the pedal push-up lever 71 rotates around the detection shaft 52.

  The vehicle locking device 3 has a pedal 72. The pedal 72 includes a substantially rectangular pedal body 72a and a pedal link plate 72b disposed at one end of the pedal body 72a in the longitudinal direction. The pedal body 72a rotates at the other end in the longitudinal direction around a fixed shaft 72c disposed between the two side surfaces 21b and 21b of the wheel rail 21 and the two side surfaces 31b and 31b of the wheel rail 31. It is installed as possible. Thereby, the pedal 72 can rotate centering on one end thereof.

  The pedal link plate 72b penetrates through the through-hole 75 (see FIG. 3) formed in the wheel rails 21, 31 in a state where the pedal body 72a is disposed on the wheel rails 21, 31, so that the wheel rails 21, It protrudes to the back side of 31. And the through-hole 72c is formed in the front-end | tip part which protrudes to the back side of 21 and 31 of the pedal link board 72b. A pedal push-up lever 71 is inserted into the through hole 72c. Therefore, for example, when the pedal body 72a is pushed down by a wheel load or the like from a state where one end of the pedal body 72a is lifted, the pedal push-up lever 71 is also pushed down. The pedal push-up lever 71 rotates about the detection shaft 52 by this pressing force, and the detection shaft 52 also rotates with this rotation.

  A detection plate 73 is fixed to the end of the detection shaft 52 in the housing 41. In addition, a winding spring 74 as an urging member and a press detection sensor 75 as a parking detection sensor are disposed inside the housing 41.

  The detection plate 73 includes a detection plate main body 73a formed in a substantially rectangular shape, a through hole 73b, and a sensor plate that is bent toward the motor 62 from around the through hole 73b on the tip side of the detection plate main body 73a. Part 73c. The detection plate main body 73a is fixed to the detection shaft 52 at one end in the longitudinal direction. The through hole 73b is formed near the other end in the longitudinal direction of the detection plate main body 73a. A part of the sensor plate portion 73c is arranged on the side surface of the eccentric link plate 61 on the right side surface portion 41d side in FIG.

  The winding spring 74 has a coil part 74a and a pair of hook parts 74b formed at both ends of the coil part 74a. One hook portion 74 b of the pair of hook portions 74 b is hung on the through hole 73 b of the detection plate 73. The other hook portion 74b of the pair of hook portions 74b is hung on the back surface of the upper surface portion 41a of the housing 41 (not shown). As a result, a force in the direction of lifting the pedal push-up lever 71 is biased to the detection shaft 52. Further, when the bicycle is not riding on the pedal 72 by the urging force of the winding spring 74, one end of the pedal body 72a attached to the wheel rails 21, 31 is lifted from the wheel rails 21, 31 ( (See FIG. 3).

  The press detection sensor 75 detects the position of the detection plate main body 73a. In particular, the position of the detection plate main body 73a in a state where one end of the pedal main body 72a is in contact with or close to the wheel rails 21 and 31. Is detected. As the press detection sensor 75, for example, a transmission type optical sensor may be used. The press detection sensor 75 outputs a detection signal when the light receiving element of the transmissive optical sensor stops receiving light. In this embodiment, the press detection sensor 75 is disposed on the sensor substrate 101 together with the closed position detection sensor 65 and the open position detection sensor 66. In addition, the sensor substrate 101 is fixed to the chassis 102 described above, and is disposed in a direction perpendicular to the surface of the upper surface portion 41 a of the housing 41.

  FIG. 9 is a block diagram showing a control system of the collecting unit 4 and the bicycle parking system in FIG.

  The collecting unit 4 includes a timer 81 that outputs time information, a recording unit 82 that stores data, an input key 83, a display unit 84, a fee collection unit 85 into which bills and money are inserted, and the vehicle lock device 3. A motor drive unit 86 for energizing the motor 62 and a microcomputer. By executing a parking control program (not shown), the microcomputer performs a parking detection unit 91, a lock control unit 92 as an energization control unit, a fee calculation unit 93, a deposit metering unit 94, and an energization control unit. The unlocking control unit 95 is realized. The parking control program can be stored in the recording unit 82 using a computer-readable recording medium such as a compact disk (not shown) or a transmission medium such as an electric communication line as a medium.

  When a detection signal is input from the press detection sensor 75, the parking detection unit 91 reads time information at the input timing of the detection signal from the timer 81, and causes the recording unit 82 to record the read time information as a parking start time. Is.

  The lock control unit 92 causes the motor drive unit 86 to start energization after the detection signal is input to the parking detection unit 91. In addition, when the detection signal is input from the closed position detection sensor 65, the locking control unit 92 stops energization by the motor driving unit 86.

  The period from when the detection signal is input to the parking detection unit 91 until the locking control unit 92 starts energization of the motor drive unit 86 can be set to an arbitrary time. That is, as soon as a detection signal is input to the parking detection unit 91, the locking control unit 92 may be set to start energization of the motor drive unit 86. For example, after the detection signal is input to the parking detection unit 91, 20 The locking control unit 92 may be set to start energization of the motor driving unit 86 after a predetermined time such as minutes elapses.

  When the low rack unit 1 or the high rack unit 2 to be cleared is specified by, for example, a unique identification number for each rack unit, the charge calculation unit 93 starts parking of the rack unit from the recording unit 82. In addition to reading the time, the current time information is read from the timer 81, and the charge is calculated based on the time difference therebetween. Further, the fee calculation unit 93 displays the calculated fee on the display unit 84.

  The deposit metering unit 94 calculates a fee input to the fee collection unit 85. Then, the deposit weighing unit 94 notifies the unlocking control unit 95 when the charged fee is equal to or higher than the fee calculated by the fee calculating unit 93.

  The unlock control unit 95 causes the motor drive unit 86 to start energization when notified from the deposit metering unit 94. In addition, when the detection signal from the open position detection sensor 66 is input, the unlocking control unit 95 stops energization by the motor driving unit 86.

  Next, the overall operation of the bicycle parking system according to the present invention will be described.

  A person who has ridden a bicycle places the bicycle on, for example, a wheel rail 21 for a low rack. Specifically, the bicycle can be placed on the low rack wheel rail 21 by pushing the bicycle from the lower rear end side of the low rack wheel rail 21 toward the front end side. At this time, since the front wheel of the bicycle gets over the roller 23 provided in the middle of the wheel rail 21 for the low rack, the bicycle is held so as not to fall back. Moreover, since the guide member 22 is provided in the wheel rail 21 for low racks, even if the hand is released from the bicycle, the bicycle does not fall down and fall from the wheel rails 21 for low rack. The front wheel of the bicycle parked in the low rack unit 1 is placed on the pedal 72.

  The pedal 72 is pushed down by the placement of the front wheel, that is, the weight of the parked bicycle. When the pedal 72 is pushed down, the pedal push-up lever 71 is also pushed down by the pedal link plate 72b. Since the pedal push-up lever 71 rotates around the detection shaft 52, the detection shaft 52 rotates when the pedal push-up lever 71 is pushed down. The detection plate 73 fixed integrally with the detection shaft 52 rotates together with the detection shaft 52. When the sensor plate portion 73c of the detection plate 73 enters between the light emitting element and the light receiving element of the press detection sensor 75, the press detection sensor 75 outputs a detection signal.

  When the detection signal from the press detection sensor 75 is input to the parking detection unit 91, the parking detection unit 91 reads time information at the input timing of the detection signal from the timer 81, and uses the read time information as the parking start time. As shown in FIG.

  Further, the lock control unit 92 causes the motor drive unit 86 to start energizing the motor 62 after the detection signal is input to the parking detection unit 91. The output shaft 62b of the motor 62 starts to rotate by energization by the motor drive unit 86, and the eccentric cam 64 also starts to rotate by the rotation that decelerates the rotation of the output shaft 62b. As the eccentric cam 64 rotates, the drive lock arm 53 and the driven lock arm 54 rotate in the closing direction. When a detection signal is input from the closed position detection sensor 65, the locking control unit 92 stops energization by the motor drive unit 86.

  In a state in which a detection signal from the closed position detection sensor 65 is output, the other end of the drive lock arm 53 and the other end of the driven lock arm 54 are in contact with or close to each other. Further, since the other end of the drive lock arm 53 and the other end of the driven lock arm 54 contact or approach each other, an annular ring is formed. Therefore, this annular ring and the wheel rim mounted on the pedal 72 are chained. Are connected to each other. That is, the wheels are sandwiched between the drive lock arm 53 and the driven lock arm 54. As a result, even if an attempt is made to pull out the bicycle from the low rack unit 1, the bicycle wheel cannot be pulled out because the wheel rim of the bicycle is caught by the drive lock arm 53 and the driven lock arm 54. That is, the bicycle is locked to the low rack unit 1.

  Next, the bicycle departure operation will be described. A person who wants to leave the bicycle from the previous low rack unit 1 operates the input key 83 to designate the low rack unit 1. The charge calculation unit 93 reads the parking start time of the low rack unit 1 designated by the input key 83 from the recording unit 82 and reads the current time information from the timer 81. The current time at this time is the parking end time. Then, the fee calculation unit 93 calculates a parking fee based on the time difference between the parking start time and the parking end time, and causes the display unit 84 to display the calculated parking fee.

  A person who wants to leave the bicycle inputs the parking fee displayed on the display unit 84 to the fee collection unit 85. The deposit metering unit 94 notifies the unlocking control unit 95 when the fee input to the fee collection unit 85 exceeds the fee calculated by the fee calculation unit 93. If the input fee exceeds the parking fee, the deposit metering unit 94 may return the difference to the fee collection unit 85.

  The unlocking control unit 95 immediately starts energization of the motor driving unit 86 upon receiving a notification from the deposit weighing unit 94. When the motor drive unit 86 is energized, the output shaft 62b of the motor 62 starts to rotate in the same direction as when locked, and the eccentric cam 64 also starts to rotate by rotating the output shaft 62b decelerated. The drive lock arm 53 and the driven lock arm 54 are rotated in the opening direction according to the movement accompanying the rotation of the eccentric cam 64. When the detection signal from the open position detection sensor 66 is input, the unlocking control unit 95 stops energization by the motor driving unit 86.

  In a state where the detection signal is output from the open position detection sensor 66, the other end of the drive lock arm 53 and the other end of the driven lock arm 54 are in the most distant state. Therefore, a person who wants to leave the bicycle can pull out the bicycle from the low rack unit 1.

  The operation of the bicycle parking system when the bicycle is parked in the high rack unit 2 is the same as that when the bicycle is parked in the low rack unit 1 described above, and the description thereof is omitted.

  As described above, in the bicycle parking system according to this embodiment, the bicycles parked in the low rack unit 1 and the high rack unit 2 can be locked and unlocked according to the payment of the parking fee. it can. In addition, the bicycle parking system according to this embodiment can manage the parking of bicycles in the low rack unit 1 and the high rack unit 2.

  In particular, the wheel lock device 3 according to this embodiment includes a drive lock arm 53 that locks the wheel, an eccentric link plate 61 that can rotate together with the drive lock arm 53, a motor 62 that rotates the output shaft 62b by energization, It has an eccentric cam 64 that rotates together with the output shaft 62b and a long hole 61b that is formed in the eccentric link plate 61 and into which the eccentric cam 64 is inserted. Therefore, the wheel lock device 3 according to this embodiment rotates the eccentric cam 64 by the rotation of the output shaft 62b of the motor 62, and the eccentric link plate 61 into which the eccentric cam 64 is inserted by the displacement accompanying the rotation of the eccentric cam 64. The drive lock arm 53 can be swung together with the eccentric link plate 61. Therefore, the drive lock arm 53 can be opened and closed by using a simple motor 62 that can rotate the output shaft 62b in one direction by energization.

  The wheel lock device 3 according to this embodiment includes a closed position detection sensor 65 that detects a state in which the wheel is locked by the drive lock arm 53 based on the position of the eccentric link plate 61, and the drive lock arm 53 is opened. An open position detection sensor 66 for detecting the state of the eccentric link plate 61 based on the position of the eccentric link plate 61, and the motor 62 is based on the detection of the eccentric link plate 61 by the closed position detection sensor 65 or the open position detection sensor 66. The energization is stopped. Therefore, a simple motor 62 that can rotate the output shaft 62b in one direction by energization is used to control whether the wheel is locked by the drive lock arm 53 and the drive lock arm 53 is open. can do. In addition, since the drive lock arm 53 is locked by opening and closing only by the rotation of the motor 62, it is easily determined whether or not the wheel is locked by visually checking the open / close state of the drive lock arm 53. can do.

  As shown in FIG. 5, the wheel lock device 3 according to this embodiment has the eccentric cam 64 in contact with the eccentric link plate 61 at the cylindrical outer peripheral portion and locks the wheel by the drive lock arm 53. In addition, a position 64d where the eccentric link plate 61 and the eccentric cam 64 are in contact with each other, a center 64c of the outer peripheral portion of the eccentric cam 64, and a rotation center (63a) of the eccentric cam 64 are positioned on a substantially straight line. For this reason, when the drive lock arm 53 or the driven lock arm 54 is opened in a state where the wheels are locked by the drive lock arm 53, the force that the eccentric link plate 61 acts on the eccentric cam 64 by the opening force. Is substantially a force in a direction from the contact point 64d toward the rotation center 63a of the eccentric cam 64. Moreover, the tangent line of the eccentric cam 64 at the portion 64d where the eccentric link plate 61 is in contact with the direction of the force that the eccentric link plate 61 acts on the eccentric cam 64 by this opening force is substantially perpendicular. Therefore, the force that the eccentric link plate 61 acts on the eccentric cam 64 by the force to open the drive lock arm 53 and the driven lock arm 54 is the direction in which the eccentric cam 64 rotates (the tangential direction at the contact 64d of the eccentric cam 64). ) Is hardly generated. As a result, even if the drive lock arm 53 and the driven lock arm 54 are opened while the wheels are locked by the drive lock arm 53, the eccentric cam 64 is difficult to rotate due to the opening force. The locked state of the wheel by the driven lock arm 54 can be maintained.

  In addition, the wheel lock device 3 according to this embodiment includes a speed reduction unit 63 that decelerates between the output shaft 62a and the eccentric cam 64 so that the rotational speed of the eccentric cam 64 is lower than the rotational speed of the output shaft 62b. Is provided. For this reason, the force for rotating the eccentric cam 64 is increased by the speed reduction unit 63 and acts on the output shaft 62 b of the motor 62. Accordingly, the resistance force of the cogging torque acting between the rotor and the stator becomes extremely large, and even when the motor 62 is not energized, even if force is applied in the direction of opening both the lock arms 53 and 54. Both lock arms 53 and 54 hardly move. For this reason, the force transmitted to the eccentric cam 64 is also reduced, and the eccentric cam 64 is difficult to turn. As a result, it is possible to maintain the wheel lock state by the drive lock arm 53 and the driven lock arm 54 while using a small motor 62 having a low output.

  The wheel lock device 3 according to this embodiment is rotatably supported by a substantially rectangular housing 41 and a front portion 41b of the housing 41, and a drive lock arm 53 and a driven lock arm 54 are provided outside the housing 41. And a drive shaft 51 in which the eccentric link plate 61 is disposed in the housing 41.

  If this configuration is employed, the motor 62, the eccentric cam 64, and the eccentric link plate 61 can be disposed in the housing 41 by pivotally supporting the drive shaft 51 on the front portion 41 b of the housing 41. As a result, the motor 62, the eccentric cam 64, and the eccentric link plate 61 can have a dustproof and waterproof structure that is unlikely to get wet with water such as rain or collect dust.

  The wheel lock device 3 according to this embodiment includes a driven lock arm 54 that forms a substantially ring for locking a wheel together with the drive lock arm 53, and an engagement portion 55 formed at one end of the drive lock arm 53. And an engagement portion 56 formed at one end of the driven lock arm 54, and the engagement portion 55 of the drive lock arm 53 and the engagement portion 56 of the driven lock arm 54 are fitted into each other. The engaging portions 55 and 56 are arranged to face each other and to be rotatable.

  For this reason, the driven lock arm 54 can be swung together with the drive lock arm 53. Further, the driven lock arm 54 swings in the reverse direction to the drive lock arm 53. As a result, it is possible to ensure an opening angle that is approximately twice that of the case where only the drive lock arm 53 is swung and opened. Conversely, for example, even if the diameter of the eccentric cam 64 is reduced and the angle at which the drive lock arm 53 is swung is substantially halved, the same opening angle as that when the drive lock arm 53 is swung open is secured. Can do. Thereby, the wheel locking device 3 can be reduced in size and weight. It is to be noted that the same effect can be obtained even if the engaging portion 55 is only the convex portion and the engaging portion 56 is only the concave portion, or the relationship between them is reversed.

  The wheel lock device 3 according to this embodiment is rotatably supported by a substantially rectangular housing 41 and a front portion 41b of the housing 41, and a drive lock arm 53 is disposed outside the housing 41. A drive shaft 51 in which the eccentric link plate 61 is disposed in the housing 41, and a detection shaft that is arranged in parallel with the drive shaft 51 and rotatably supported on the front portion 41b of the housing 41 and is rotated by the wheel of the parked vehicle. 52, and the driven lock arm 54 is rotatably supported by the detection shaft 52.

  If this configuration is adopted, the driven lock arm 54 is arranged outside the housing 41 so as to face the drive lock arm 53 and to be rotatable by using the detection shaft 52 rotated by the wheel of the parked vehicle. be able to. In addition, the drive shaft 51 and the detection shaft 52 are pivotally supported on the front portion 41b of the housing 41, and the motor 62, the eccentric cam 64, the eccentric link plate 61, and the like are disposed in the housing 41. In addition, the eccentric link plate 61 and the like can be provided with a dustproof and waterproof structure that is unlikely to get wet or collect dust.

  In the wheel lock device 3 according to this embodiment, the drive lock arm 53 and the driven lock arm 54 are made of engineering plastic such as polycarbonate resin. For this reason, even if the drive lock arm 53 and the driven lock arm 54 hit the locked wheel or the like, it is difficult to damage the wheel.

  The wheel lock device 3 according to this embodiment detects a pedal 72 that is depressed by a parked wheel, a detection plate 73 that is displaced when the pedal 72 is depressed, and a detection plate 73 that is in a state where the pedal 72 is depressed. And a winding spring 74 that urges the force in a direction in which the detection plate 73 moves away from the press detection sensor 75. For this reason, it can be detected by the press detection sensor 75 that the pedal 72 is depressed, that is, that the vehicle wheel is in a correct position where it can be locked. Then, the motor 62 can be controlled based on the detection signal of the press detection sensor 75 to lock the wheel.

  The wheel lock device 3 according to this embodiment is rotatably supported by a substantially rectangular parallelepiped housing 41 and a front portion 41 b of the housing 41, and a detection shaft in which a detection plate 73 is disposed in the housing 41. 52 and a pedal push-up lever 71 that is rotatably disposed around the detection shaft 52 and pushes up the pedal 72 in accordance with the urging force of the winding spring 74 outside the housing 41. For this reason, the detection shaft 52 can be pivotally supported on the front portion 41 b of the housing 41, and the detection plate 73, the press detection sensor 75, and the winding spring 74 can be disposed in the housing 41. As a result, the detection plate 73, the press detection sensor 75, and the winding spring 74 can have a dust-proof and waterproof structure that is unlikely to get wet with water such as rain or collect dust. When the bicycle leaves the low rack unit 1 or the high rack unit 2, the pedal 72 is pushed up by the force of the winding spring 74 and returns to the original state.

  The parking system according to this embodiment includes wheel rails 21 and 31 on which wheels ride, a wheel lock device 3 that locks wheels on the wheel rails 21 and 31, and energization to a motor 62 of the wheel lock device 3. A locking control unit 92 and an unlocking control unit 95 for controlling. Thereby, the drive lock arm 53 and the driven lock arm 54 are opened and closed by using a simple motor 62 that rotates in one direction, whereby the wheels on the wheel rails 21 and 31 can be locked.

  The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications and changes can be made without departing from the scope of the present invention. is there. For example, in the above-described embodiment, the motor 62 whose rotational direction is one direction is used.
