  However, in the vehicle locking device of Patent Document 1, when a fork or a pole is molded by an insert molding method, a coating portion is coated in addition to a portion necessary for suppressing abnormal noise, and waste is generated in an elastomer or the like. Further, the main body of the fork or pole to be pressed tends to have variations in thickness and the like, and if insert molding is performed using these, burrs are likely to occur in the coating portion. In such a fork or pole in which burrs are generated, an operation failure or a meshing failure occurs. Therefore, it is necessary to separately perform a deburring process on the coating portion, and the manufacturing efficiency of the fork or pole is lowered. Furthermore, in order to perform insert molding, not only a machine dedicated to insert molding is required, but the shape of the main body of the fork and pole, for example, needs to be a shape that considers insert molding, etc. The number of work steps required for manufacturing increases.

Then, the inner peripheral surface of the surface side within the boss and the rear surface side in the boss, it is not preferable that is substantially the same diameter as the pivot shaft hole. In this case, the first rocking shaft can be easily inserted into the rocking shaft hole, the front-side inner boss, and the rear-surface-side inner boss when the vehicle locking device is assembled, and it is difficult for defective assembly to occur.

The cover may be formed with a step portion that approaches the base plate around the swing shaft hole. Then, the fork body has preferably be protrudes radially outward direction than the step portion. In this case, after the buffer member is assembled to the fork body to form a sub-assembly, it is easy to perform an operation of sandwiching the sub-assembly between the base plate and the cover.

In the buffer member of the present invention, at least one of the front surface portion and the back surface portion may have an outer boss extending outwardly coaxially with the shaft hole. Then, the outer boss, that obtained the first pivot shaft is a positioning part is inserted.

  In this case, if the first swing shaft is inserted into the outer boss while the first arm is inserted into the connection portion, the position of the buffer portion relative to the first arm or the like can be restricted. For this reason, the vehicle locking device can be easily assembled. In addition, the first swing shaft stably contacts the buffer member with a large area via the outer boss, so that the durability of the buffer member is improved and the operating noise can be reduced.

  As shown in FIGS. 2 and 3, the latch is surrounded by a peripheral wall 17 b between the lower portion of the flat portion 15 a of the base plate 15 about 2/3 and the facing portion 17 a of the lock cover 17. A chamber 1a is formed. A fork 3 and a pole 5 are built in the latch chamber 1a.

  As shown in FIGS. 4 to 6, the fork 3 includes a fork main body 41 made of a plate material made of an iron-based material, and a rubber cushioning member 43.

  The fork main body 41 has a base portion 410 having a shaft hole 41a penetrating in the thickness direction. As shown in FIG. 7, the pin 19 is inserted into the shaft hole 41 a together with the boss 17 k of the lock cover 17. As shown in FIG. 4, the base portion 410 is provided with first and second arms 411 and 412 that protrude in a direction away from the shaft hole 41a. The first arm 411 is pressed by the striker S in an unlatched state. The second arm 412 forms a notch 413 for allowing the striker S to enter between the second arm 412 and the first arm 411. A pole engaging portion 414 that engages with the pole 5 protrudes from the tip of the first arm 411. The base 410 is provided with a third arm 415 that protrudes in a direction away from the shaft hole 41a. The third arm 415 is located on the opposite side to the notch 413 in the first arm 411.

Further, the back surface portion 432 has a back surface hole 432a that is coaxial with the shaft hole 41a. As shown in FIG. 7, the surface hole 431 a has substantially the same diameter as the outer peripheral surface of the boss 17 k of the lock cover 17. On the other hand, the back surface hole 432a has a larger diameter than the outer peripheral surface of the boss 17k. For this reason, the surface hole 431a is a positioning portion P that regulates the position of the buffer portion 434 relative to the first arm 411 by inserting the boss 17k and the pin 19 therethrough. Further, the fork main body 41 protrudes outward in the radial direction by a length a from the step portion 17 m of the lock case 17.

  After the buffer member 43 is assembled to the fork main body 41 to form a sub-assembly, the sub-assembly is sandwiched between the base plate 15 and the lock cover 17. As a result, the fork 3 can swing around the pin 19 as shown in FIGS. That is, the fork 3 switches to a latched state in which the striker S is locked in the entrances 15g and 17h, or an unlatched state in which the striker S is released from inside the entrances 15g and 17h.

  As shown in FIG. 1, the pole 5 has an arm 5 a extending in a direction away from the pin 21. The arm 5a extends from the notch 17g toward the inclined portion 15b and projects forward from the notch 15l to the inclined portion 15b.

The actuator cover 25 includes a base portion 25a facing the base portion 27a of the actuator base 27, a peripheral wall 25b extending perpendicularly from the base portion 25a above and on both sides of the base portion 25a, and slightly below the base portion 25a below the base portion 25a. And a tongue portion 25c extending while being inclined.

  Between the base portion 25a of the actuator cover 25 and the base portion 27a of the actuator base 27, an actuator chamber 7a is formed that is surrounded by peripheral walls 25b and 27b on the upper side and both sides. The actuator 9, the worm 29, the worm wheel 31, and the first to third terminals 11, 13, and 35 are held in the actuator chamber 7a.

The rotation shaft of the actuator 9 extends in parallel with the base portion 25a and the base portion 27a, and a worm 29 is fixed to the rotation shaft. The worm wheel 31 is housed rotatably in the actuator chamber 7 a in parallel with the base portion 25 a and the base portion 27 a and meshes with the worm wheel 31. The worm wheel 31 is biased to the initial position by a torsion coil spring 33 provided between the base portion 25 a of the actuator cover 25. A cam 31 a is formed on the surface of the actuator base 27 on the base 2 7 a side of the worm wheel 31. The arm 5a of the pole 5 is pressed by the cam 31a, and the pole 5 swings from the fixed position to the open position.

  Each end 11a, 13a, 35a of the first terminal 11, the second terminal 13, and the third terminal 35 functions as three male terminals in the connector 7b formed by the actuator cover 25 and the actuator base 27.

  The first terminal 11 extends downward from one end 11a, and the other end 11b projects downward from the actuator chamber 7a. The other end 11 b is pressed against the third arm 415 of the fork 3. The second terminal 13 also extends downward from the one end 13 a, and the other end 13 b is bent so that the lower end approaches the first terminal 11. The second terminal 13 and the third terminal 35 are connected to the actuator 9.

  When the actuator part A is fixed to the lock part L, the screws 2 and 4 are passed through the assembly holes 15j and 15k of the base plate 15, and the screws 2 and 4 are screwed into screw holes (not shown) of the actuator base 27. A locking device is thus obtained.

  In this locking device, as shown in FIGS. 2 and 3, when the fork 3 is rotated clockwise and the notch 413 is aligned with the entrances 15g and 17h, the striker S can enter the entrance when the trunk lid is closed. Enter 15g, 17h and notch 413. As a result, the fork 3 rotates counterclockwise around the pin 19 against the urging force of the tension spring 23. Then, the pole 5 rotates counterclockwise around the pin 21 by the urging force of the tension spring 23, and the fork engaging portion 5 b engages with the pole engaging portion 414. For this reason, the fork 3 is in a latched state in which the striker S is locked in the entrances 15g and 17h. For this reason, the trunk lid is locked to the vehicle body.

  At this time, in this locking device, the buffer member 43 is assembled to the fork main body 41 by being inserted into the first arm 411. Thereby, in the fork 3, the collision with the striker S can be buffered by the buffer portion 434 of the buffer member 43 while securing rigidity by making the fork main body 41 made of metal. For this reason, according to this locking device, it is possible to suppress abnormal noise from the fork 3 when the trunk lid is locked to the vehicle body.

  Further, in this locking device, since the buffer member 43 is guided by the base plate 15 and the lock cover 17, it is difficult for abnormal noise to occur when the fork 3 swings. In particular, in this locking device, since the buffer member 43 functions as a cushion with respect to the fork engaging portion 5b, it is possible to suppress the generation of noise when the pole 5 collides. Further, when the pole 5 is fixing the fork 3, the fork engaging portion 5 b presses the connecting portion 433 of the buffer member 43, so that the buffer member 43 is not easily detached from the fork main body 41.

  In this state, the other end 11b of the first terminal 11 shown in FIG. 1 is pressed in a direction away from the other end 13b of the second terminal 13 by the third arm 415 of the fork 3, and the first terminal 11 and the second terminal 13 is separated from the lower end of the other end 13b. Thereby, it can be confirmed that the lamp in the vehicle interior is turned off and the trunk lid is closed.

  When the user turns on the switch for opening the trunk lid and the actuator 9 rotates, the arm 5a of the pole 5 is pressed to the right by the cam 31a, and the pole 5 swings from the fixed position to the open position. For this reason, the fork engaging portion 5 b is separated from the pole engaging portion 414 of the fork 3, and the fork 3 rotates clockwise around the pin 19 by the urging force of the tension spring 23. For this reason, the fork 3 enters an unlatched state in which the striker S is released from the entrances 15g and 17h. For this reason, the trunk lid is unlocked. The same applies when a lever (not shown) is operated. The same applies to the case where the user swings the arm 5a protruding from the notch 15l to the right, such as when the amount of power stored in the battery is small.

  In this state, since the other end 11b of the first terminal 11 is separated from the third arm 415 of the fork 3, the other end 11b contacts the other end 13b of the second terminal 13 due to the spring property of the first terminal 11. . Thereby, it can confirm that the lamp | ramp in a vehicle interior lights and the trunk lid is open | released.

  In this locking device, since the buffer member 43 is provided only on the first arm 411 in the fork main body 41, the material of the buffer member 43 is unlikely to be wasted.

  Moreover, according to this locking device, since it is not necessary to form the fork 3 by insert molding, the restriction on the shape of the fork main body 41 is eased, and a process for removing burrs after insert molding is not necessary. Yes.

  Furthermore, in the buffer member 43, the position of the buffer portion 434 is regulated by the positioning portion P. Therefore, when the buffer member 43 is assembled to the fork main body 41, it is easy to align the buffer portion 434 with the fork main body 41. ing. For this reason, according to this buffer member 43, the manufacturing efficiency of the fork 3 can be made high.

Further, in the fork 3 to which the buffer member 43 is assembled, the pole engaging portion 414 is directly engaged with the pole 5 outside the buffer member 43. Since the pole engaging portion 414 is made of metal having excellent rigidity, the fork 3 can be suitably engaged with the pole 5. Thereby, the pole 5 can fix the fork 3 reliably.

  Furthermore, in the buffer member 43, the surface portion 431 has a surface hole 431a that is coaxial with the shaft hole 41a. Further, the back surface portion 432 has a back surface hole 432a that is coaxial with the shaft hole 41a. And the surface hole 431a is made into the same diameter as the outer peripheral surface of the boss | hub 17k of the lock cover 17, and the surface hole 431a is made into the positioning part P by inserting the boss | hub 17k and the pin 19 in the surface hole 431a. Therefore, in this buffer member 43, if the boss 17k and the pin 19 are inserted into the front surface hole 431a and the back surface hole 432a while the first arm 411 is inserted into the connection portion 433, the buffer portion for the first arm 411 and the like. The position of 434 can be restricted. Further, since the back surface hole 432a has a larger diameter than the outer peripheral surface of the boss 17k, the tip of the boss 17k of the lock cover 17 does not ride on the buffer member 43 when the lock device is assembled, resulting in poor assembly. hard. Further, a step portion 17m is formed on the lock cover 17, and the fork main body 41 protrudes in a radially outward direction from the step portion 17m. For this reason, after the buffer member 43 is assembled to the fork main body 41 to form a sub-assembly, it is easy to perform an operation of sandwiching the sub-assembly between the base plate 15 and the lock cover 17. For this reason, the locking device can be easily assembled.
