DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. This example is an application example as a lock device for a trunk of a vehicle.
[0016]
In FIG. 1 and FIG. 2, V is a vehicle provided with a lock device L having an electric opener mechanism. The locking device L is fixed to the lower end portion of the trunk lid TL, and a meshing mechanism capable of restraining and releasing the striker S provided on the vehicle body by engaging and disengaging a latch member and a locking plate, which will be described later, and the device main body And an electric opener mechanism that can move the operating portion of the locking plate located in the direction of disengagement. A first handle H1 disposed inside the trunk lid TL is connected to the distal end of the operating portion of the locking plate via a cable C as a first operating force transmission member, and a second operating force is also provided. A second handle H2 capable of moving the locking plate in the disengagement direction from the interior of the vehicle interior, for example, the armrest AR of the rear seat RS, is connected via a wire W as a transmission member.
[0017]
First, the locking device L will be described with reference to FIGS. 3 and 4. Reference numeral 1 denotes a base plate attached to a fixed position of the lower end portion of the trunk lid TL. As shown in FIG. 4, the base plate 1 is bent in a substantially V shape in a side view, and a meshing mechanism 10 is formed on one end side thereof, and a resin case ( An unlocking mechanism 20 is configured in the apparatus main body 2.
[0018]
As shown in FIG. 3, the meshing mechanism 10 includes a latch member 11 that can rotate in the directions of arrows A1 and A2 about the axis O1, and an arrow about the axis O2, as in a general door lock mechanism. A locking plate 12 that can rotate in the directions B1 and B2 and a spring 13 that urges the latch member 11 in the direction of arrow A1 and urges the locking plate 12 in the direction of arrow B2 are provided. In the state of FIG. 3, the meshing mechanism 10 is in a restrained state in which the striker S on the vehicle body side is restrained by the latch member 11, that is, in a state in which the trunk lid TL is restrained to the closed position. That is, the latch member 11 is in the rotation position in the direction of arrow A2 that restrains the striker S by the engaging portion 11A, and the rotation return in the direction of arrow A1 is prevented by the locking plate 12. In order to release the restraint of the striker S, the locking plate 12 may be rotated in the arrow B1 direction and the latch member 11 may be rotated and returned in the arrow A1 direction.
[0019]
The lock release mechanism 20 releases the engagement of the meshing mechanism 10 by rotating the locking plate 12 in the arrow B1 direction. The lock release mechanism 20 of the present example includes an electric opener mechanism 30 for rotating the locking plate 12 in the disengagement direction, an emergency handle 40 as the first handle H1, and a first for an abnormal power supply. An unlocking mechanism connected to the loop 50 as the second handle H2 is provided.
[0020]
The operating portion 12A of the locking plate 12 is located between the base 1 and the case 2, and the distal end portion 12B of the operating portion 12A is bent as shown in FIG. Projecting outward from the case 2 from the portion 2A. The opening 2 </ b> A is a long hole extending in the left-right direction in FIG. 3 so as to follow the movement locus of the tip 12 </ b> B accompanying the rotation of the locking plate 12.
[0021]
The electric opener mechanism unit 30 is configured inside the case 2 and includes a worm wheel (hereinafter simply referred to as “wheel”) 31 that can rotate around an axis O3 in FIG. The wheel 31 is connected to an electric motor 33 via a worm 32, and is rotated by a driving force of the motor 33. When the motor 33 is not driven, the wheel 31 is rotated and returned by a spring (not shown). A base end portion 34 </ b> A of the release lever 34 is pin-coupled at a fixed position of the wheel 31. A substantially U-shaped front end 34B of the release lever 34 is guided so as to be slidable in the left-right direction in FIG. 3 at a position facing the front end 12B of the locking plate 12 located inside the case 2.
[0022]
The electric opener mechanism 30 configured as described above pushes the release lever 34 to the right in FIG. 3 when the wheel 31 is rotated by the driving force of the motor 33, thereby the tip of the release lever 34. The portion 34B pushes the distal end portion 12B of the locking plate 12, and rotates the locking plate 12 in the disengagement direction (arrow B1 direction). On the other hand, when the motor 33 is not driven, a spring (not shown) rotates the wheel 31 and pulls the release lever 34 to the left in FIG. 3, thereby rotating the locking plate 12 in the direction of arrow B2. It is possible to return.
[0023]
In the above-described embodiment, the lock device includes the electric opener mechanism. However, the lock device may be operated by a separate electric opener mechanism via a linkage or the like.
[0024]
The handle 40 in the emergency unlocking mechanism is provided at a fixed position in the trunk room by means of attachment such as a hook-and-loop fastener, and is connected to one end of a cable 41 as a first operating force transmission member. An annular connecting portion 41A is provided at the other end of the cable 41, and is fitted from the outside of the case 2 into the distal end portion 12B of the locking plate 12 protruding outward from the case 2 as shown in FIG. It is.
[0025]
Further, a clip 52 as a retaining member is fitted to the distal end portion 12B of the locking plate 12 on the outside of the connecting portion 41A. The clip 52 is provided with a rectangular hole 53 having a surface 53A having a surface 53A in surface contact with the distal end portion 12B in the engagement release direction or the operation direction of the locking plate 12, and apex at the distal end portion 12B other than the surface 53A. Are formed in a plurality of portions (three in this example) that are in point contact with each other. Further, the clip 52 is formed with a hole 54 to which one end of a wire 51 as a second operating force transmission member having a loop 50 formed at the end in the operating direction of the locking plate 12 is connected. The clip 52 prevents the connecting portion 41 </ b> A of the cable 41 from coming off from the distal end portion 12 </ b> B of the locking plate 12.
[0026]
Further, the wire 51 may be held at an arbitrary position in the middle of the wire 51 by preventing the slack with a clip 55 or the like provided inside the trunk lid TL.
[0027]
Thus, the handle 40 connected to the distal end portion 12B of the locking plate 12 via the cable 41 is pulled by a person trapped by mistake in the trunk room, so that the locking plate 12 is disengaged in the disengagement direction ( Rotate in the direction of arrow B1). Further, the loop 50 connected to the distal end portion 12B of the locking plate 12 via the wire 51 rotates the locking plate 12 in the disengagement direction (arrow B1 direction) by being pulled by a person from the passenger compartment. Let
[0028]
The handle 40 and the loop 50 are pulled only in an emergency or abnormality, and are usually provided at fixed positions in the trunk room. When the locking plate 12 is normally rotated by the electric opener mechanism 30 or the like, the cable 41 and the wire 51 are bent to allow the locking plate 12 to rotate. Therefore, by connecting the handle 40 and the loop 50 to the locking plate 12, the normal rotation of the locking plate 12 is not hindered. Moreover, since the connection part 41A of the cable 41 and the front-end | tip part 34B of the release lever 34 oppose across the peripheral wall part of the opening part 2A in the case 2, as shown in FIG. 3, there is no possibility that they mutually interfere.
[0029]
The connecting portion 41 </ b> A and the clip 52 of the cable 41 can be externally attached from the outside of the case 2. That is, the connecting portion 41A of the cable 41 is first fitted and connected from the outside of the case 2 to the distal end portion 12B of the locking plate 12 protruding from the opening 2A of the case 2, and then the clip 52 is connected from the outside of the case 2. Install. Then, the wire 51 bent in a U shape may be locked in the hole 54 of the clip 52. Therefore, the cable 41 and the wire 51 can be attached very easily by external attachment.
[0030]
In addition, as an existing locking device (not shown) to which the handle 40 is not connected, for example, when a trunk locking device in which the opening 2A is not formed in the case 2 and the cover is not attached is assumed. The handle 40 and the loop 50 can be externally attached by a relatively small design change. That is, by forming the opening 2A in the case 2 of the existing locking device and projecting the tip 12B of the locking plate 12 from the opening 2A, the handle 40 and the loop 50 are removed from the outside of the case 2. Can be attached.
[0031]
Here, still another embodiment of the clip as a retaining member fitted into the distal end portion 12B of the locking plate 12 will be described with reference to FIG. The aforementioned clip 52 has a flat plate shape and has a slight weak point in its holding force.
[0032]
The present embodiment is an improvement on that point. That is, the clip 56 of this embodiment is formed with a hole 53 having a rectangular basic shape and a hole 54 to which one end of the wire 51 as the second operating force transmission member is connected. . The clip 56 is formed with a flange wall 57A that faces the distal end portion 12B in the engagement release direction or the operation direction of the locking plate 12 so as to face the rectangular hole 53, and is opposed to the locking plate 12 by frictional force. A triangular engagement claw 57B is formed, and a rectangular engagement claw 57C that is orthogonal to the engagement claw 57B and that protrudes inward in a relationship facing the flange wall 57A is formed. Further, a stepped portion 12 </ b> C that engages with a square engaging claw 57 </ b> C is formed at the distal end portion 12 </ b> B of the locking plate 12. The flange wall 57A is formed by being bent in the direction opposite to the insertion direction of the clip 56, and the engaging claw 57C has a tip biased in the same bending direction.
[0033]
The clip 56 is press-fitted into the distal end portion 12B of the locking plate 12, and the mounting is completed when the square engaging claw 57C engages with the stepped portion 12C. This state is shown in FIG. 6B. Even if a turning force or the like is input to the clip 56, the clip 56 is reliably prevented from coming off by the engagement of the engagement claw 57C with the step portion 12C. The Further, since the flange wall 57A can contact the front end portion 12B of the locking plate 12 with a wide contact area and the repulsive force of the engaging claw 57C can be obtained with certainty, the clip 56 is held by the front end portion 12B in a stable posture. The Therefore, according to the clip 56, the connecting portion 41A of the cable 41 can be prevented from coming off from the distal end portion 12B of the locking plate 12 more reliably.
[0034]
The operation force transmission member is not limited to a flexible member such as a cable or a wire and is arbitrary, and may be a rigid rod or the like as long as it does not hinder normal rotation of the locking plate 12. . Further, the form of the handle 40 and the loop 50 is not limited to the illustrated example, and the form is arbitrary as long as it can be grasped and operated by hand.
[0035]
Further, the installation position of the second handle may be anywhere as long as the locking plate can be moved in the disengagement direction from the vehicle interior, and of course may be provided in the vehicle interior.
[0036]
【The invention's effect】
As described above, according to the present invention, the locking plate can be moved and operated in the disengagement direction in the trunk room via the first operating force transmission member at the tip of the operating portion of the locking plate. Because the second handle that can move the locking plate in the disengagement direction from the vehicle interior via the second operating force transmission member is connected to the tip of the operating portion of the locking plate while connecting the handle, The trunk lid can be opened even in an emergency or when the power feeding system is abnormal, and an unexpected situation can be avoided.
[0037]
The operating portion of the locking plate is formed at a portion facing the operating portion of the apparatus main body and protrudes outward through an opening extending in the moving direction of the operating portion of the locking plate. A connecting portion provided at one end of the first operating force transmission member is connected to the tip portion from the outside of the apparatus main body and further provided with a retaining member on the outside. It is also possible to avoid deterioration in assembly workability without significant design change of the locking device.
[0038]
Since one end of the second operating force transmission member is connected to the retaining member, the configuration is simple and the assembly is easy.
[0039]
Furthermore, the retaining member is a flat clip, and has a surface that is in surface contact with the distal end portion in the operation direction of the locking plate, and a plurality of portions that are substantially point-contacted with the distal end portion other than the surface. Since it is formed and the hole to which the second operation force transmission member is connected is formed in the operation direction, the connection portion can be protected and prevented from coming off only by attaching the clip.
[0040]
Further, the retaining member is a clip in which a flange wall that is in surface contact with the distal end portion in the operation direction of the locking plate and a claw that is engaged with the distal end portion on a surface other than the surface are formed. In this case, when the claw that is held in a stable posture and the claw facing the flange wall of the clip engages with the step formed on the tip, the holding force is reliably obtained. Disengagement is prevented.
