Description

The present invention relates to a vehicle hood lock system including a hood lock device for holding a vehicle hood in a closed position.

Conventionally, vehicle hood lock systems include a hood lock device that is placed on the vehicle body and holds the hood in a closed position by engaging a striker on the hood side, and a hood lock device that is placed near the driver's seat and has a bowden cable. The opener device is connected to the hood lock device via an operating force transmission member such as the like, and releases the hood lock device based on a user's manual operation, thereby making it possible to open the hood.

For example, a hood lock device in a hood lock system described in Patent Document 1 includes a latch that can engage with a striker on the hood, and a ratchet that engages with the latch to prevent rotation of the latch in the opening direction.

The latch has an engagement groove having a first groove for holding the hood in a fully closed position and a second groove for holding the hood in a slightly opened position from the fully closed position by engaging with the striker. from a latch position (corresponding to the fully closed position of the hood) where the striker engages with the first groove to a half latch position (corresponding to the half open position of the hood) where the striker engages the second groove. Thereafter, the striker can be rotated to an unlatched position (corresponding to a position where the hood is further opened than the half-open position) and vice versa, where the striker is separated from the second groove.

When the latch is in the latched position, the ratchet holds the latch in the latched position by engaging with a first pawl provided on the outer periphery of the latch, and when the latch is in the half-latched position, the ratchet The latch is held in the half-latched position by engaging with the second pawl provided on the outer periphery, and is configured not to engage with either the first or second pawl when the latch is in the unlatched position. .

To open the hood in the fully closed position from inside the vehicle, the user first operates the opener handle of an opener device located near the driver's seat in a predetermined direction. As a result, the ratchet releases and separates from the first pawl of the latch, rotating the latch from the latch position to the half-latch position, lifting the hood from the fully closed position to the half open position, and the ratchet , engages with the second claw portion of the latch. Next, operate the opener handle again in the same direction as the previous operation. As a result, the ratchet is released again and disengaged from the second pawl portion of the latch, thereby rotating the latch from the half-latched position to the unlatched position, allowing the striker to disengage from the second groove portion. Next, the user can open the hood by moving to the front of the vehicle, inserting his/her hand into the gap between the half-opened hood and the vehicle body, and then lifting the hood.

German Patent Application No. 10 2010 062 700

However, in the hood lock system described in Patent Document 1, the first operation direction of the opener handle that enables the hood to be opened from the fully closed position to the half-open position, and the direction in which the hood is moved from the half-open position to the further open direction. Because the directions in which the opener handle is operated the second time are in the same direction, the user may misunderstand that the user has operated the opener handle twice even though he or she has only operated it once, or If the amount of operation of the opener handle is insufficient for the second time, a problem may occur in which the user is unable to open the hood even though the user has moved to the front side of the hood.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a vehicle hood lock system that allows the hood to be opened reliably based on the operation of an opener device.

According to the present invention, the above problem is solved as follows.
In the hood lock system according to the present invention, a striker on the hood side, which is fixed to a vehicle body and pivotally supported to the vehicle body so as to be openable and closable, enters with the closing operation of the hood and exits with the opening operation of the hood. a primary latch mechanism supported by the base plate and capable of holding the hood in a fully closed position by engaging with the striker that has entered the striker entry groove; is in a half-open position, which is slightly more open than the fully closed position, is movable from a standby position where it can engage the striker that has come off the primary latch mechanism to a retracted position where it cannot engage the striker; a hood locking device having a secondary latch elastically held in each position by a force means, the hood locking device being disposed near the driver's seat and connected to the primary latch mechanism via a first operating force transmitting member; Operation in one direction from the neutral position brings the primary latch mechanism into an unlatched state, and is connected to the secondary latch via a second operation force transmission member, and operation in the other direction from the neutral position brings the primary latch mechanism into an unlatched state. and an opener device including an opener handle that allows the latch to be moved from the standby position to the retracted position.

Preferably, the opener device is further connected to the primary latch mechanism via the first operating force transmission member, and is interlocked with rotation of the opener handle in one direction from a neutral position and rotated in the other direction. a first lever that is not interlocked with the rotation of the opener handle, and a first lever that is connected to the secondary latch via the second operating force transmission member and that is interlocked with the rotation of the opener handle from the neutral position in the other direction and that rotates in one direction. and a spring that elastically holds the opener handle, the first lever, and the second lever at neutral positions, respectively.

Preferably, one end of the biasing means of the hood lock device is latched to the secondary latch and the other end is latched to the base plate, so that the biasing means of the hood lock device can be moved between the standby position and the retracted position of the secondary latch. The turnover spring is configured such that the biasing direction of the biasing force applied to the secondary latch is reversed at an intermediate position between the two.

Preferably, the secondary latch has an abutment portion that enters the striker entry groove when the secondary latch is in the retracted position, and when the striker comes into contact with the abutment portion due to a closing operation of the hood, the It is forcibly moved from the retracted position to the standby position against the urging force of the urging means.

The secondary latch is prevented from moving from the standby position to the retracted position by abutting the striker when the striker is engaged with the primary latch mechanism.

According to the present invention, the first operation of the opener handle in one direction in the opener device causes the primary mechanism in the hood locking device to change from the latched state to the unlatched state, thereby placing the hood in the half-open position, and then operating the opener handle in one direction for the first time. By the second operation in the other direction, the secondary latch is moved from the standby position to the retracted position and held at the retracted position, so that the hood can be reliably opened based on the two operations of the opener handle. can.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
As shown in FIG. 1, the hood lock system according to the present invention includes a hood lock device 1 attached to a radiator core support (hereinafter referred to as "vehicle body") in the front engine room of a vehicle V such as an automobile, and A manual opener device 20 is provided near the seat.

The hood lock device 1 is a primary latch that can hold the hood H in a fully closed position by engaging a striker S provided at the front of the hood H, whose rear part is pivotally supported on the vehicle body so that it can be opened and closed in the vertical direction. It includes a mechanism part 2 and a secondary latch mechanism part 3 that can be held in a partially open position slightly opened upward from a fully closed position.

The opener device 20 has a manually operable opener handle 21, and by operating the opener handle 21 in one direction for the first time, the primary latch mechanism 2 is brought into an unlatched state, the hood H is brought into a half-open position, and then By operating the opener handle 21 in the other direction for the second time, the secondary latch 13 of the secondary mechanism section 3 is released and held in the retracted position where it cannot engage the striker S, thereby opening the hood H. enable.

As shown in FIGS. 2 to 5, the hood lock device 1 includes, in addition to the above-described primary latch mechanism section 2 and secondary latch mechanism section 3, a metal base plate for supporting the primary latch mechanism section 2 and the secondary mechanism section 3. 4. The base plate 4 is fixed to the vehicle body by bolts (not shown), and has left and right screw holes 41, 41 on both the left and right sides into which bolts are screwed, and a striker in the upper center of the vehicle as the hood H is opened and closed. It has a striker entry groove 42 that is open at the top so that S can advance and retreat in the vertical direction.

The primary latch mechanism section 2 includes a primary latch 6 and a lift lever 7 that are rotatably supported by a latch shaft 5 facing the rear side of the base plate 4 in the front-back direction, and a ratchet shaft 8 facing the rear side of the base plate 4 in the front-back direction. A ratchet 9 that is rotatably supported, a lift spring 10 that applies a biasing force to the lift lever 7 in the lift direction (clockwise in FIG. 4, counterclockwise in FIG. 5), and a lift spring 10 that is engaged with the ratchet 9. It includes a ratchet spring 11 that applies a biasing force in the mating direction (counterclockwise in FIG. 4, clockwise in FIG. 5).

The primary latch 6 has a substantially central portion supported by the latch shaft 5 on the rear side of the base plate 4, and is rotatable from the latched position shown in FIGS. 6 and 7 to the unlatched position shown in FIGS. 8 and 9, and vice versa. When the hood H is closed, the striker S that enters the striker entry groove 42 engages with the engagement groove 61, so that the striker S moves approximately 45 degrees from the unlatched position shown in FIGS. 8 and 9 in the latching direction (counterclockwise in FIGS. 8 and 9). Rotate and move to the latched position shown in FIG. Note that the engagement groove 61 is formed between an upper arm portion 62 and a lower arm portion 63 provided on the primary latch 6.

The ratchet 9 is supported on the rear side of the base plate 4 by a ratchet shaft 8 whose upper end faces in the front-rear direction, and is urged in the engagement direction (for example, counterclockwise in FIG. 6) by a ratchet spring 11. When the hood H is in the fully closed position, the striker S is engaged with the engagement groove 61 of the primary latch 6, and the primary latch 6 is in the latched position shown in FIG. 6, the ratchet 9 is in the position shown in FIG. When the primary latch 6 is in the engaged position, the step-like claw part 91 provided at the center engages with the engaging part 64 provided at the tip of the lower arm part 63 of the primary latch 6, thereby moving the primary latch 6 to the latched position. to hold.

In this embodiment, as shown in FIG. 6, the striker S is engaged with the engagement groove 61 of the primary latch 6, the primary latch 6 is in the latched position, and the ratchet 9 is engaged with the primary latch 6. The state in which the striker S is disengaged from the engagement groove 61 of the primary latch 6 and the primary latch 6 is in the unlatched position is defined as the unlatched state, as shown in FIG. It is defined as

Further, the ratchet 9 has a connecting portion 92 formed at its lower end, and the connecting portion 92 is connected to a first lever 22 of the opener device 20, which will be described later, via a first operating force transmitting member 15 constituted by a Bowden cable. Ru. As a result, when the hood H is in the fully closed position, when the opener handle 21 of the opener device 20 is operated in one direction (for example, a pulling operation backward), the operation is transmitted via the first operation force transmission member 15. The ratchet 9 rotates a predetermined angle clockwise from the engagement position shown in FIG. 6 against the biasing force of the ratchet spring 11 and moves to the release position shown in FIG. The portion 91 is disengaged from the engagement portion 64 of the primary latch 6, allowing the primary latch 6 to freely rotate in the unlatching direction (clockwise in FIGS. 6 and 7).

When the primary latch 6 becomes free to rotate in the unlatching direction, the biasing force of the lift spring 10 acting on the lift lever 7 causes the primary latch 6 to rotate in the unlatching direction from the latch position shown in FIG. 7 and move to the unlatching position shown in FIG. Then, the striker S engaged with the engagement groove 61 is lifted upward. Thereby, the hood H is lifted from the fully closed position to the half open position. When the hood H is in the half-open position, it is possible to insert a hand into the gap between the front end of the hood H and the vehicle body.

The lift lever 7 has a substantially central portion supported by the latch shaft 5 on the rear side of the base plate 4, and is biased in the lift direction (counterclockwise in FIG. 6) by the biasing force of the lift spring 10. 6 with some play in the rotational direction. The biasing force of the lift spring 10 is transmitted to the hood H via the lift lever 7 and the striker S, and acts as a lifting force that lifts the hood H from the fully closed position to the half open position, and also unlatches the primary latch 6 from the latched position. It also acts as a rotational force to rotate it to a certain position.

As can be understood from FIGS. 6 to 9, the slight play in the rotational direction of the lift lever 7 with respect to the primary latch 6 described above is caused by the protrusion 63a provided on the lower arm portion 63 of the primary latch 6 so as to protrude rearward. This is achieved by engaging an engagement hole 71 provided in the lift lever 7 with some play in the rotational direction.

The lift lever 7 is provided with a lift arm portion 72 that overlaps the rear side of the lower arm portion 63 of the primary latch 6 and that can slightly enter the engagement groove 61 of the primary latch 6 from below. When the hood H is in the fully closed position and the primary latch 6 is held in the latched position as shown in FIG. By strongly pressing the striker S engaged with the engagement groove 61 against the upper edge of the engagement groove 61 in the primary latch 6, that is, the upper arm portion 62, the striker S is prevented from wobbling within the engagement groove 61. , which in turn suppresses the rattling of the hood H.

Next, the secondary latch mechanism section 3 will be explained. The secondary latch mechanism 3 includes a secondary latch 13 that is rotatably supported at a predetermined angle by a secondary latch shaft 12 facing in the front-rear direction on the front side of the base plate 4, and a predetermined position of the secondary latch 13 by rotation of the secondary latch 13. As a boundary, a turnover spring 14 is included as a biasing means that reverses the biasing direction of the biasing force in the rotational direction that is applied to the secondary latch 13.

As described above, the lower end of the secondary latch 13 is supported by the secondary latch shaft 12 on the front side of the base plate 4 so as to be rotatable by a predetermined angle in the left and right direction, and the connecting portion 131 provided on the upper side is supported by the second operating force. By being connected to one end of the transmission member 16, it is connected to a second lever 23, which will be described later, of the opener device 20 via the second operating force transmission member 16. As a result, when the hood H is in the half-open position, when the opener handle 21 of the opener device 20 is operated in the other direction (for example, pushing forward), the secondary latch 13 is activated based on the operation of the opener handle 21. , from the standby position shown in FIG. 8 where the lower end portion 136 is in contact with the first stopper portion 43 (see FIG. 4) of the base plate 4, rotates counterclockwise by a predetermined angle against the biasing force of the turnover spring 14; As shown in FIG. 9, by rotating to the retracted position where the base plate 4 contacts the second stopper portion 44, the base plate 4 is held at the retracted position by the urging force of the turnover spring 14.

The turnover spring 14 is constituted by a torsion spring, and one arm portion 14a is hooked to the secondary latch 13, and the other arm portion 14b is hooked to the base plate 4, so that when the secondary latch 13 rotates, At an intermediate position between the standby position and the retracted position of the secondary latch 13, the urging direction of the urging force acting on the secondary latch 13 in the rotational direction is reversed. Specifically, when the secondary latch 13 is closer to the standby position than the intermediate position, a biasing force is applied to the secondary latch 13 in the standby direction (clockwise in FIGS. 6 to 8), and 13 is closer to the retracted position than the intermediate position, a biasing force is applied to the secondary latch 13 in the retracting direction (counterclockwise in FIG. 9).

Further, the secondary latch 13 includes an arm portion 132 extending upward along the striker entry groove 42 , a hook portion 133 provided at the upper end of the arm portion 132 , and a hook portion 133 provided on both sides of the striker entry groove 42 . It has a first abutting part 134 that faces the first abutting part 134, and a second abutting part 135 that extends diagonally upward to the right from the upper end of the first abutting part 134.

As shown in FIGS. 6 to 8, when the secondary latch 13 is held at the standby position, the hook portion 133 is located within the striker movement locus of the striker S accompanying the opening and closing of the hood H, and the hook portion 133 By engaging the striker S that has come out of the engagement groove 61 from above, the hood H is held in the half-open position, and the secondary latch 13 is held in the retracted position as shown in FIG. In such a case, the hood H is retracted outside the striker movement restriction and the hood H can be opened and closed freely at a position where it does not engage with the striker S.

When the hood H is in the fully closed position, the striker S is engaged with the engagement groove 61 of the primary latch 6, and the secondary latch 13 is in the standby position, the first contact portion 134 is in the position shown in FIG. It is located close to the side surface of the striker S and in a position where it can come into contact with the side surface of the striker S. As a result, when the secondary latch 13 is in the standby position, even if the secondary latch 13 is rotated from the standby position in the retracting direction (counterclockwise in FIG. It comes into contact with the side surface and prevents the secondary latch 13 from moving from the standby position to the retracted position. Therefore, in the latched state in which the striker S is engaged with the engagement groove 61 of the primary latch 6, the secondary latch 13 cannot be moved from the standby position to the retracted position. Thereby, malfunction of the secondary latch 13 can be prevented.

For example, as shown in FIG. 6, when the secondary latch 13 is held at the standby position, the second contact portion 135 is located on the right side of the striker entry groove 42, and as shown in FIG. When the striker 13 is held at the retracted position, it enters the striker entry groove 42. As a result, when the secondary latch 13 is held in the retracted position by the biasing force of the turnover spring 14, the striker S, which has entered the striker entry groove 42 from above, is tilted as the hood H closes. By coming into contact with the upper surface of a certain second contact portion 135, the secondary latch 13 can be forcibly moved from the retracted position to the standby position against the biasing force of the turnover spring 14.

Next, the opener device 20 will be explained.
The opener device 20 includes a base plate 24 fixed near the driver's seat, an opener handle 21, a first lever 22, and a second lever 23, each of which is independently rotatably supported by a pivot shaft 25 facing left and right on the base plate 24. and a spring 26 that applies a biasing force in the rotational direction to the opener handle 21, the first lever 22, and the second lever 23.

The spring 26 has a coil portion 26c wound around the pivot 25, and one end portion 26a hooked to the lower front edges of the first and second levers 22, 23 and the rear edge of the first elongated hole 241 provided in the base plate 24, respectively. The opener handle 21 and the first lever 22 are connected to each other by hooking the other end portions 26b to the lower rear edges of the first and second levers 22 and 23 and the front edge of the second elongated hole 242 provided in the base plate 24, respectively. and the second lever 23 are each elastically held at the neutral position shown in FIG.

The opener handle 21 has a connecting shaft portion 211 provided on its side that can slide in the rotational direction around the pivot 25 through the first arc hole 221 of the first lever 22 and the second arc hole 231 of the second lever 23. By being inserted into the rear end of the first circular arc hole 221 and the front end of the second circular arc hole 231, the spring 26 is held in the neutral position shown in FIG. Based on this, it is possible to rotate a predetermined angle forward (clockwise) and backward (counterclockwise) about the pivot shaft 25 from the neutral position against the biasing force of the spring 26 .

The first lever 22 is rotatably supported by the base plate 24 by a pivot 25, the connecting protrusion 211 of the opener handle 21 is inserted into the first circular arc hole 221 as described above, and the upper end is used for transmitting the first operating force. It is connected to the other end of the member 15. As a result, as shown in FIG. 10, when the opener handle 21 is in the neutral position, the first lever 22 is elastically held in the neutral position by the biasing force of the spring 26, and as shown in FIG. 21 rotates backward from the neutral position, the first lever 22 rotates as the connection shaft portion 211 of the opener handle 21 abuts the rear end of the first circular arc hole 221 of the first lever 22. The first operating force transmitting member 15 is pulled backward, and the ratchet 9 is rotated from the engagement position shown in FIG. 6 in the releasing direction as shown in FIG. 7. In this case, since the connecting shaft portion 211 simply moves relatively backward within the second circular arc hole 231 of the second lever 23, the second lever 23 is held at the neutral position.

The second lever 23 is rotatably supported by the base plate 24 by a pivot 25, the connecting protrusion 211 of the opener handle 21 is inserted into the second circular arc hole 231 as described above, and the second lever 23 is connected to the secondary latch 13 at the lower end. The other end of the second operating force transmitting member 16 is connected. As a result, as shown in FIG. 10, when the opener handle 21 is in the neutral position, the second lever 22 is elastically held in the neutral position by the biasing force of the spring 26, and as shown in FIG. 21 rotates forward from the neutral position, the connection shaft 211 of the opener handle 21 comes into contact with the front end of the second circular arc hole 231 of the second lever 23, so that the second lever 23 is connected to the opener handle 21. By rotating forward together, the secondary latch 13 can be rotated from the standby position shown in FIG. 8 to the retracted position shown in FIG. 9 via the second operating force transmission member 16. In this case, the first lever 22 is held at the neutral position while the first lever 22 is stopped by simply moving the connecting shaft portion 211 relatively forward within the first circular arc hole 221 of the first lever 22.

Note that the opener device 20 is not limited to the above-described configuration, and various changes are possible. For example, when the door of the driver's seat is in a closed state, the opener handle 21 is disabled from operating forward, backward, or both from the neutral position, and is enabled only when the door is open. In this way, erroneous operation of the opener handle 21 can be prevented while the vehicle is running.

Next, the operation of the hood lock system according to this embodiment will be explained with reference to FIGS. 6 to 12.
When the hood H is in the fully closed position, as shown in FIG. , the striker S is engaged with the engagement groove 61 of the primary latch 6. In this case, the striker S is designed to prevent rattling between the lift arm portion 72 of the lift lever 7 and the upper arm portion 62 of the primary latch 6 due to the biasing force of the lift spring 10 acting on the lift lever 7. is sandwiched between. The secondary latch 13 is elastically held in the standby position by the biasing force of the turnover spring 14. Further, the opener handle 21, first lever 22, and second lever 23 of the opener device 20 are each elastically held at the neutral position shown in FIG. 10.

Furthermore, when the hood H is in the fully closed position, as shown in FIG. is prevented from rotating from the standby position in the retracting direction. Therefore, in this state, the secondary latch 13 cannot be moved to the retracted position by operating the opener handle 21 of the opener device 20 before the primary latch mechanism section 2 is brought into the unlatched state.

When the opener handle 21 of the opener device 20 is pulled backward by a predetermined angle from inside the room while the hood H is in the fully closed position, the open handle 21 and the first lever 22 are pulled backward by a predetermined angle, as shown in FIG. angular rotation, and the rotation is transmitted to the ratchet 9 via the first operating force transmission member 15. As a result, the ratchet 9 rotates from the engagement position shown in FIG. 6 in the release direction (clockwise in FIG. 6) about the ratchet shaft 8, and as shown in FIG. It comes off from the engaging part 64. As a result, the primary latch 6 rotates from the latch position shown in FIG. 7 to the unlatch position shown in FIG. 8 due to the biasing force of the lift spring 10 acting on the lift lever 7, and this rotation raises the striker S. Lift hood H to the half-open position. As shown in FIG. 8, the raised striker S can engage with the hook portion 133 of the secondary latch 3 from below, so that the hood H is held in the half-open position.

Next, the opener handle 21 of the opener device 20 is pushed forward from inside the room to temporarily stop it at the neutral position, or it is allowed to pass through the neutral position and rotated to the position shown in FIG. 12. Accordingly, the second lever 23 rotates forward by a predetermined angle, and the rotation is transmitted to the secondary latch 13 via the second operating force transmission member 16. As a result, the secondary latch 13 rotates from the standby position shown in FIG. 8 in the retracting direction (counterclockwise in FIG. 8) around the secondary latch shaft 12, and rotates to the retracting position shown in FIG. The hook portion 133 is elastically held in the retracted position by the biasing force of the spring 14, and moves to a position where the hook portion 133 does not engage with the striker S. After the secondary latch 13 is moved to the retracted position, the opener handle 21 is returned to the neutral position by the biasing force of the spring 26.

After operating the opener handle 21 twice, the secondary latch 13 is elastically held in the retracted position, so the user moves to the front side of the hood H and inserts his/her hand into the gap between the front end of the hood H and the radiator grill. Hood H can be opened just by inserting it.

When the hood H is open, as shown in FIG. 9, the primary latch 6 is stopped at the unlatched position, and the secondary latch 13 is stopped at the retracted position. When the hood H is closed in this state, the striker S enters the striker entry groove 42, passes through the side of the hook portion 133 in the secondary latch 13, and engages with the engagement groove 61 of the primary latch 6. It abuts against the second abutting portion 135 of the secondary latch 13 . As a result, the secondary latch 3 is rotated from the retracted position shown in FIG. 9 to the standby position shown in FIG. 6 against the biasing force of the turnover spring 14, and is elastically held. Further, the primary latch 6 rotates from the unlatched position shown in FIG. 9 to the latched position shown in FIG. , engages with the engaging portion 64 of the primary latch 6. As a result, the primary latch mechanism 2 enters the latched state shown in FIG. 6, and the hood H is held in the fully closed position.

As described above, in this embodiment, the first operation of the opener handle 21 in the opener device 20 that brings the primary latch mechanism section 2 of the hood lock device 1 into the unlatched state, and the first operation of the opener handle 21 of the opener device 20 that moves the secondary latch 13 to the retracted position are performed. By setting the second operation of the handle 21 in a different direction, erroneous operation of the opener handle 21 can be suppressed.

In addition, in the second operation to move the secondary latch 13 of the opener handle 21 to the retracted position, when the secondary latch 13 moves closer to the retracted position than the intermediate position between the standby position and the retracted position, the turn Since the secondary latch 13 is moved to the retracted position by the biasing force of the overspring 14, even if the amount of operation of the opener handle 21 is insufficient, the secondary latch 13 can be reliably moved to the retracted position. Thereby, the hood H can be reliably opened from outside the vehicle based on the user's operation of the opener handle 21 in the opener device 20.
