Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

On the contrary, this application is intended to cover any alternatives, modifications, equivalents, and alternatives that may be included within the spirit and scope of the application as defined by the appended claims. Furthermore, in the following detailed description of the present application, certain specific details are set forth in order to provide a better understanding of the present application. It will be apparent to one skilled in the art that the present application may be practiced without these specific details.

The embodiment of the application relates to a switching lock mechanism of a lock, the lock and a vehicle. The vehicle may include a bicycle, an electric vehicle, a balance car, an electric bicycle, a tricycle, etc. The lock can be used for protecting the safety of the vehicle, preventing the vehicle from being stolen, or preventing the vehicle from being illegally used, and the like. In some embodiments, the latch may be separate from the vehicle or may be mounted on the vehicle. In some alternative embodiments, the application scenario of the lockset may not be limited to vehicles. For example, the lock can also be applied to a door lock, a cabinet lock, a box lock and other scenes, and the application is not limited thereto.

Generally, a lockset may include a locking pin and a switch lock mechanism. Wherein the locking pin can be used to change the state of the lock (e.g., open or close the lock). Specifically, the latch may have a variety of shapes, for example, the latch may include an annular latch (e.g., a shackle), a linear latch, a hook-shaped latch, and the like. For example, a lock applied to a vehicle may be a locking ring that may be used to pass through a spoke gap of the wheel to limit rotation of the wheel when in a locked state. Accordingly, the lock may further comprise a pin resetting device for resetting the pin when the lock is unlocked. The locking pin resetting device can be a spring, such as a compression spring, a tension spring, a coil spring and the like. The locking and unlocking mechanism can be used for controlling the mechanical assembly to limit the lock pin, and further controlling the lockset to be opened or closed.

The switching lock mechanism may generally include: the lock bolt driving device can be used for driving the lock bolt to move. Accordingly, the lock pin is generally provided with a lock hole or a groove for accommodating the lock tongue, and the lock tongue can be clamped into or separated from the lock hole or the groove on the lock pin through movement. When the lock tongue is clamped into the lock hole or the groove, the lock opening and closing mechanism limits the movement of the lock pin, so that the lock can be closed; when the lock tongue is separated from the lock hole or the groove, the lock opening and closing mechanism relieves the limitation on the movement of the lock pin, and the lock pin can reset under the action of the lock pin resetting device, so that unlocking can be realized.

The lock opening and closing mechanism, the lock, the vehicle and the control method and system of the lock according to the embodiment of the present application will be described in detail with reference to fig. 1 to 3. It should be noted that the following examples are only for explaining the present application and do not constitute a limitation to the present application.

The on-off lock mechanism of lock 100 may include a deadbolt 130 and a deadbolt actuator. Specifically, the tongue driving means may be used to drive the movement of the tongue 130.

In some embodiments, the deadbolt actuation means may include a deadbolt toggle 140 and a deadbolt reset 131. Deadbolt toggle 140 may be used to apply a driving force to the deadbolt to toggle the deadbolt 130 for movement. Deadbolt reset 131 may be used to store and release energy during deadbolt movement to perform the reset function of deadbolt 130. Specifically, a deadbolt reset 131 (e.g., a spring) may be drivingly connected to deadbolt 130. In an embodiment of the present application, the dead bolt resetting means 131 may be a compression spring. In alternative embodiments, the deadbolt reset means 131 may also be a tension spring, a coil spring, or the like. In some embodiments, the deadbolt toggle 140 may include a power device and a toggle portion; the toggle part is in transmission connection with the power device and is used for moving under the driving of the power device so as to toggle the bolt 130 to move. In the embodiment of the present application, the power device may be a motor 142, and the toggle part may be a cam 141. In some embodiments, the cam 141 may be shaped as two cylinders with end surfaces fixedly attached to each other. The large cylinder is fixedly arranged on a rotating shaft of the motor 142, the end face of the small cylinder is fixedly connected with the end face of the large cylinder, and the position of the small cylinder deviates from the rotating center of the large cylinder. Preferably, the circumference of the small cylinder may be tangential to the circumference of the large cylinder. Preferably, the diameter of the small cylinder may be less than half of the diameter of the large cylinder, e.g., the diameter of the small cylinder may be 1/3, 1/4, etc. of the diameter of the large cylinder. The latch 130 may be provided with a second protrusion 133 for the cam 141 (e.g., a small cylinder on the cam 141) to abut against. When the cam 141 rotates, the cam 141 (e.g., a small cylinder on the cam 141) is pressed against and separated from the second protrusion 133, so as to drive the latch 130 to move.

In some embodiments, the motor 142 may be a geared motor. In some alternative embodiments, deadbolt toggle 140 may also be a reciprocating drive mechanism such as a crank and rocker mechanism. For example, the power device may be a motor and the toggle part may be a rocker. In some alternative embodiments, deadbolt toggle 140 may also be a magnetically actuated device. For example, the power device may be an electromagnet, and the toggle part may be a magnetic block driven by the electromagnet.

In an embodiment of the present application, the switch lock mechanism may further include a sensor 160, and the sensor 160 may be used to determine the position of the deadbolt 130 using magnetic field induction.

In some embodiments, the sensor 160 may include a magnetic induction sensor, and the deadbolt 130 may include an element for generating a magnetic field. Therefore, the magnetic induction sensor can determine the position of the locking bolt 130 by sensing the intensity of the magnetic field generated by the element on the locking bolt 130. In an embodiment of the present application, the sensor 160 may be a hall sensor 161. The element on the latch bolt for generating a magnetic field may be a magnet 162 fixed to the latch bolt 130. Specifically, the hall sensor 161 may include a hall position reference sensor, a hall zero position sensor, a hall travel sensor, a hall gear sensor, a hall proximity switch, and the like. In some alternative embodiments, the sensor 160 may also include an electromagnetic induction sensor (e.g., a fluxgate sensor, an eddy current sensor, etc.), a magnetoresistive sensor (e.g., a giant magnetoresistive sensor, a magnetostrictive sensor, etc.), or the like.

In some embodiments, the sensor 160 may be used to detect whether the deadbolt 130 reaches a predetermined position. In the embodiment shown in fig. 1-3, the sensor 160 may be a hall sensor 161, and the latch tongue 130 is provided with a magnet 162 for activating the hall sensor 161. The hall sensor 161 generates an electric signal reflecting the detected magnitude of the magnetic field by receiving the intensity of the magnetic field generated by the magnet 162, and the controller determines the position of the latch bolt 130 by processing (e.g., comparing and operating) the electric signal. Specifically, the hall sensor 161 may be disposed at a position: when the latch tongue 130 is at a position lifted by the latch tongue driving means away from the latch pin 120, the hall sensor 161 can be opposed to the latch tongue magnet 162. With the above arrangement, the hall sensor 161 can receive a stronger magnetic field, so that the determination can be made more accurate. Preferably, as shown in fig. 2, a magnet 162 may be provided at a connection of the latch bolt 130 and the latch bolt resetting device 131, and a hall sensor 161 is provided at a farthest position where the latch bolt is driven by the latch bolt driving device to be away from the latch pin 120. In some embodiments, the electrical signal output by the hall sensor 161 may be proportional to the strength of the magnetic field it detects. Specifically, a threshold may be set, that is, when the electric signal output by the hall sensor 161 is greater than the threshold, the controller may determine that the latch tongue 130 has reached the preset position. Compared with other sensing elements, the Hall sensor 161 has the characteristics of no contact, low power consumption, long service life, high response frequency and the like, and can reliably work in various outdoor severe environments after being packaged by resin.

In some embodiments, a deadbolt actuation mechanism may be used to actuate movement of the deadbolt 130 based on the position of the deadbolt. Specifically, the latch driving device may be configured to stop after the latch 130 continues to move for a period of time after moving to the preset position. For example, when the latch driving means includes a power device and a toggle portion, the power device (e.g., the motor 142) may be configured to drive the toggle portion (e.g., the cam 141) to continue to move for a preset time or stop after moving after the latch 130 moves to the preset position.

In some embodiments, the switch lock mechanism may further include a controller that may be in signal communication (e.g., electrically connected) with both the sensor 160 and the deadbolt actuation mechanism (e.g., the motor 142 in the deadbolt actuation mechanism). The controller may be configured to control the deadbolt actuation mechanism based on the output signal of the sensor 160. In some embodiments, the controller may be implemented by the control system 500 described in fig. 5.

The present application further discloses a latch 100, and the latch 100 may include the switching lock mechanism described in any of the embodiments of the present application. In some embodiments, the latch 100 may further include a housing 110, a locking pin 120, and a locking pin return 121.

In the embodiment shown in fig. 1-3, latch pin 120 is movably disposed within housing 110 relative to housing 110, and latch pin 120 may include a recess 122 configured to receive at least a portion (e.g., an end portion) of locking bolt 130. In some embodiments, the locking pin 120 may be a locking ring that may be used to pass through a spoke gap of the wheel to limit rotation of the wheel when in the locked state. In some embodiments, the recess 122 in the lock pin 120 may also be a lock hole. The lock pin resetting device 121 can be in transmission connection with the lock pin 120, and the lock pin resetting device 121 can reset the lock pin 120 when unlocking. In some embodiments, the latch pin return 121 may be a spring (e.g., a tension spring). The latch tongue 130 is movably disposed in the housing 110 relative to the housing 110, such that at least a portion of the latch tongue 130 can enter and exit the lock hole or groove 122. For example, to enable the end of the locking tongue 130 to engage or disengage with the locking hole or recess 122 on the locking pin 120. The latch bolt resetting device 131 is drivingly connected to the latch bolt 130, and the latch bolt resetting device 131 can reset the latch bolt 130 when the lock is closed, for example, the latch bolt 130 is locked in the lock hole or the groove 122 of the lock pin 120. Deadbolt toggle 140 may be used to toggle deadbolt 130 relative to housing 110. The controller can receive an instruction, such as an unlocking instruction from a server or a mobile terminal, and control the bolt driving device according to the instruction. In some embodiments, the controller may implement control of other components of the latch, such as the latch strike 140, via the control system 500 shown in fig. 5. In the embodiment of the present application, the deadbolt toggle 140 and the sensor 160 may both have signal connections with the controller; the controller may be used to control deadbolt toggle 140 based on the position of deadbolt 130.

In some embodiments, sensor 160 may determine the unlocked and locked states of lock 100 by sensing the position of locking bolt 130. In some embodiments, to further accurately identify the unlocked and locked states of the lock 100, the lock 100 may also include lock state detection means. The lock state detection device can be used to detect the unlocked or locked state of the lock 100. In the embodiment shown in fig. 1-3, the lock state detecting device may be a touch switch 170, and the latch tongue 130 may have a first protrusion 132 corresponding to the touch switch 170; the first protrusion 132 may be used to contact or disengage the tact switch 170 when the locking tongue 130 moves relative to the housing 110, so as to change the state of the tact switch 170, such as turning on or off. For example, when the deadbolt 130 moves away from the latch pin 120, the first protrusion 132 touches the tact switch 170 (e.g., closes the tact switch 170); when the latch tongue 130 moves in the direction of the latch pin 120, the first protrusion 132 is disengaged from the tact switch 170 (e.g., the tact switch 170 is turned on). The output signal of the tact switch 170 is different in different states (on or off). The tact switch 170 may be in signal connection (e.g., electrically connected) with the controller, and the controller receives an output signal of the tact switch 170, determines the position of the latch bolt 130 based on the output signal, and further determines the on-off state of the lock 100. As shown in fig. 1, the locking state is achieved when the first protrusion 132 of the locking tongue 130 is disengaged from the tact switch 170. As shown in fig. 2, the bolt 130 is in an unlocked state, and the first protrusion 132 touches the tact switch 170. In other embodiments, the first protrusion 132 may be replaced by a rod, a plate, a block, or the like, which is fixedly connected to the latch tongue 130.

In alternative embodiments, the lock state detection device may be other reasonable devices. For example, the lock state detection means may be a further sensor 160 for sensing the position of the deadbolt 130. For another example, the lock state detection device may be a photoelectric sensor; a first blocking piece can be fixedly arranged on the bolt 130; the first blocking piece is used for changing the intensity of light entering the photoelectric sensor when the lock bolt 130 moves relative to the housing 110, so as to determine the position of the lock bolt 130, and further determine the unlocking and locking states of the lock 100. In some alternative embodiments, the lock state detection device may be a tact switch 170; a protrusion (not shown) opposite to the tact switch 170 may be fixedly provided on the latch pin 120; the protrusion may be used to open or close the tact switch 170 when the locking pin 120 moves relative to the housing 110, so that the position of the locking pin 120, and thus the unlocking and locking states of the lock 100, may be determined by the state of the tact switch 170. For another example, the lock state detection device may be any device capable of determining the lock state by detecting the position or movement of the deadbolt 130 and/or the deadbolt 120.

In some embodiments, the sensor 160 may be used to sense whether the locking tongue 130 moves to a predetermined position out of the locking hole or the groove 122. In some embodiments, the preset position may be a position to which deadbolt toggle 140 is able to toggle deadbolt 130 furthest relative to deadbolt 120. The controller may be configured to control deadbolt toggle 140 to release the constraint on deadbolt 130 after deadbolt 130 moves to a preset position, and reserve a return space required when deadbolt 130 is locked. In the embodiment of the present application, the sensor 160 (e.g., the hall sensor 161) is used to sense the position of the latch tongue 130, and compared with the conventional lock 100 in which the tact switch 170 is used, the sensor 160 is in a non-contact type, has a longer service life than the tact switch 170, and is highly reliable. And because the sensor 160 is relatively durable, the cost of the latch 100 can be greatly reduced.

In an embodiment of the present application, deadbolt toggle 140 may include a motor 142 and a cam 141; the motor 142 is fixedly disposed in the housing 110, and the cam 141 is fixedly connected to a rotating shaft of the motor 142. The motor 142 is in signal communication (e.g., electrically connected) with the controller. Cam 141 may be used to toggle deadbolt 130 relative to housing 110 upon actuation of motor 142. In some embodiments, after the latch tongue 130 moves to the predetermined position out of the lock hole or the groove 122, the controller may control the motor 142 to drive the cam 141 to rotate for a predetermined time (e.g., 0.5s, 1s, 2s, etc.) or for a predetermined angle (e.g., 3 °, 5 °, 10 °, 60 °, 90 °, etc.), so as to ensure that the cam 141 is disengaged from the second protrusion 133, and the cam 141 does not obstruct the latch tongue 130 when the latch tongue 130 is pushed by the latch tongue resetting device 131 to be locked and reset. In the present application, the motor 142 is preferably a geared motor. In alternative embodiments, deadbolt toggle 140 may be implemented using other suitable means known to those skilled in the art. For example, deadbolt toggle 140 may be implemented using a reciprocating drive mechanism such as a crank and rocker mechanism.

In embodiments of the present application, as shown in FIGS. 1-3, the latch pin return 121 may be a spring, such as a tension spring. Specifically, one end of a tension spring may be fixedly disposed on the housing 110, and the other end of the tension spring may be fixedly connected to the end of the latch 120. Furthermore, the tension spring can be in a stretching state when in a locking state; and is in a reduction state in the unlocking state.

In an embodiment of the present application, the deadbolt reset 131 may be a spring, as shown in fig. 1-3. Specifically, one end of the spring may be fixedly disposed on the housing 110, and the other end of the spring may be connected to the other end of the latch tongue 130. Further, the spring may be in a compressed state in the unlocked state; and in the locking state, the lock is in a reduction state.

FIG. 4 is an exemplary flow chart of a lock control method according to some embodiments of the present application. As shown in fig. 4, the control method 400 of the lock 100 may include the steps of:

and step 410, controlling the bolt driving device to move so as to execute unlocking. Specifically, step 410 may be performed by unlocking module 510.

In some embodiments, a controller (e.g., unlocking module 510) may receive an unlock command and control movement of the bolt drive to perform unlocking based on the unlock command. The unlocking instruction can be an unlocking instruction sent by the server and/or the mobile terminal. Specifically, the locking bolt driving device can drive the locking bolt 130 to move in a direction of disengaging from the locking hole or the groove 122 until the locking bolt 130 disengages from the locking hole or the groove 122 of the lock pin 120, and the lock pin 120 is restored (for example, retracted into the housing 110) under the action of the lock pin resetting device 121 to realize unlocking.

The position of the deadbolt is determined based on the magnetic field induction, step 420. In particular, step 420 may be performed by detection module 520.

In some embodiments, a controller (e.g., detection module 520) may determine multiple positions (e.g., arbitrary positions) of the deadbolt 130 based on magnetic field induction. In some embodiments, the controller (e.g., the detection module 520) may also determine whether the locking bolt 130 reaches the preset position based on magnetic field induction. The preset position may be a position where the latch tongue 130 is far away from the lock pin of the lock (e.g., a position separated from the lock hole or the groove 122). Specifically, the controller (e.g., the detection module 520) may receive the output signal of the sensor 160 and determine the position of the deadbolt 130 based on the signal of the sensor 160.

Step 430, controlling the deadbolt driver based on the position of the deadbolt. Specifically, step 430 may be performed by deadbolt actuator control module 530.

In some embodiments, when the deadbolt 130 reaches a predetermined position, a controller (e.g., deadbolt actuator control module 530) may control the deadbolt actuator to operate for a period of time before stopping. For example, when the output signal reflects that the latch 130 moves to a preset position away from the lock hole or the groove 122, the controller may control the latch driving device to operate for a period of time and then stop, so as to control the latch striking device 140 to move to release the constraint on the latch 130 and reserve a return space required when the latch 130 is locked. The latch bolt 130 will now be urged against the lock pin 120 by the urging of the latch bolt return means 131. When the lock needs to be closed, the lock pin 120 is pulled until the lock hole or the groove 122 is aligned with the end of the lock tongue 130, and the lock tongue 130 enters the lock hole or the groove 122 under the pushing force of the lock tongue resetting device 131, so that the lock closing is completed.

In some embodiments, the deadbolt actuation means comprises deadbolt toggle 140 and deadbolt reset 131; the deadbolt toggle mechanism 140 includes a power device (e.g., a motor 142) and a toggle portion (e.g., a cam 141); the toggle part is in transmission connection with the power device and is used for moving under the driving of the power device so as to toggle the bolt 130 to move. The controller controlling the latch bolt driving device to continue to operate for a period of time and then stop may include: and controlling the power device to drive the toggle part to continuously move for a preset time or after a displacement (such as a moving distance of the edge of the cam 141 during rotation) is stopped. In some embodiments, deadbolt toggle 140 may include a motor 142 and a cam 141. Specifically, the controller may control the motor 142 to drive the cam 141 to rotate continuously for a preset time or angle, so that a distance between the cam 141 and the second protrusion 133 of the locking tongue 130 is greater than or equal to a distance between an end of the locking tongue 130 and a bottom of the locking hole or the groove 122, or a small cylinder of the cam is not located on a reset path of the locking tongue 130, and the locking tongue 130 may be reset under the thrust of the locking tongue resetting device 131 and abut against the lock pin 120.

The steps of locking the lock 100 may be: when the lock pin 120 moves relative to the housing 110 under the action of tension until the lock hole or the groove 122 on the lock pin 120 is aligned with the lock tongue 130, the lock tongue 130 moves towards the lock pin 120 under the action of the lock tongue resetting device 131 until the end of the lock tongue 130 is clamped into the lock hole or the groove 122 on the lock pin 120, so that locking is closed.

It should be noted that the above description related to the flow 400 is only for illustration and explanation, and does not limit the applicable scope of the present application. Various modifications and changes to flow 400 may occur to those skilled in the art in light of the teachings herein. However, such modifications and variations are intended to be within the scope of the present application. For example, the three steps of the control method 400 may be performed sequentially according to a flow sequence or may be performed simultaneously. For another example, step 410 may be performed first, and then steps 420 and 430 may be performed simultaneously.

FIG. 5 is an exemplary block diagram of a latch control system according to some embodiments of the present application. As shown in fig. 5, the lock control system 500 may include an unlocking module 510, a detection module 520, and a deadbolt actuator control module 530.

Specifically, the unlocking module 510 may be used to control movement of the deadbolt actuator to perform unlocking. The detection module 520 may be used to determine the position of the deadbolt 130 based on magnetic field induction. In some embodiments, the detection module 520 may also be configured to determine whether the locking bolt 130 reaches a predetermined position based on magnetic field induction. Deadbolt actuator control module 530 may be used to control the deadbolt actuator based on the position of the deadbolt 130. In some embodiments, the deadbolt actuator control module 530 may be further configured to control the deadbolt actuator to operate for a period of time and then stop when the deadbolt 130 reaches a predetermined position. In some embodiments, the latch control system 500 may also include an acquisition module. For example, the acquisition module may be used to acquire an output signal of a lock state detection device (e.g., the tact switch 170) to determine whether the lock 100 is in the unlocked or the locked state. In some embodiments, the control system 500 may further include a transmitting module for transmitting the switch state of the lock 100 to a server or a mobile terminal.

It should be understood that the system and its modules shown in FIG. 5 may be implemented in a variety of ways. For example, in some embodiments, the system and its modules may be implemented in hardware, software, or a combination of software and hardware. Wherein the hardware portion may be implemented using dedicated logic; the software portions may be stored in a memory for execution by a suitable instruction execution system, such as a microprocessor or specially designed hardware. Those skilled in the art will appreciate that the methods and systems described above may be implemented using computer executable instructions and/or embodied in processor control code, such code being provided, for example, on a carrier medium such as a diskette, CD-or DVD-ROM, a programmable memory such as read-only memory (firmware), or a data carrier such as an optical or electronic signal carrier. The system and its modules of the present application may be implemented not only by hardware circuits such as very large scale integrated circuits or gate arrays, semiconductors such as logic chips, transistors, or programmable hardware devices such as field programmable gate arrays, programmable logic devices, etc., but also by software executed by various types of processors, for example, or by a combination of the above hardware circuits and software (e.g., firmware).
