[Detailed description of the device]

[0001]

[Industrial applications]

 In the present invention, a striker is provided on one of the trunk lid and the peripheral edge of the trunk opening, and a latch member for engaging and disengaging the striker is provided on the other of the trunk lid and the peripheral edge of the trunk opening. The present invention relates to an automobile trunk lid closure device in which the latch member is pulled in via the striker to close the trunk lid.

[0002]

[Prior art]

 Conventionally, there are those equipped with a torsion bar or a gas stay so that the trunk lid can be easily opened.

The torsion bar is provided in the trunk room. For example, depending on the layout of the trunk hinge and the gas tank, the torsion bar may not interfere with these, or the trunk lid may be covered with snow, or the trunk lid and the weather strip. If the and froze, the trunk lid will be difficult to open, and if the rear spoiler is installed on the trunk lid, the torsion bar will become tired and gradually become difficult to open.

Further, in the gas stay, since the direction of the urging force changes from the opening direction to the closing direction at the midpoint between the open position and the closed position of the trunk lid, when the trunk lid is opened, the urging force of the gas stay is changed. It is difficult to open because it needs to be opened against the edge of the trunk lid and the gap between the trunk lid and the peripheral edge of the trunk opening is not wide enough, so it is difficult for the hand to enter the gap and it is also difficult to open.

On the other hand, there is a closure device in which when the latch member engages with the striker, the latch member is pulled toward the striker side by the power to forcibly close the trunk lid. When the trunk lid is opened, this device returns to the retracted start state where the latch member engaged with the striker first, and in the retracted start state, it is necessary to put a hand between the trunk and the peripheral edge of the trunk opening. Gaps are formed.

[0006]

[Problems to be solved by the device]

 However, in such a conventional closure device for a trunk lid for an automobile, due to snow or freezing, the latch member does not come off the striker, and even if it does come off, it does not jump up due to the weight of the trunk lid and is re-engaged with the striker. As a result, the closure device may be activated again, and the hand may be caught, and the trunk lid may not be opened due to repeated closing operations, which is not convenient.

The present invention has been made in view of such conventional problems, and it is necessary to surely form a gap required for holding a hand between the trunk lid and the peripheral portion of the trunk opening. In addition, it is an object of the present invention to provide a trunk lid closure device for an automobile, which has improved safety and improved usability.

A cam follower 56 is pivotally attached to the cam follower 56, and the cam follower 56 is movably fitted in the cam groove 41.

As shown in FIGS. 18 to 23, the cam groove 41 has a cam follower 56 in the cam groove 41 as the striker base 40 swings from the middle of the retracting shown in FIG. 22 to the end of the retracting shown in FIG. The swing angle of the striker base 40 becomes relatively small with respect to the moving length of the striker base, and the cam follower 56 moves at the end of retraction so that the latch member 17 can be retracted with a gradually larger force than at the start of retraction. It is formed in a substantially arc shape having a diameter slightly larger than the diameter of the circumferential shape so as to substantially follow the shape trajectory.

As shown in FIGS. 1, 18 and 23, the striker base 40 contacts the contacted portion 18 a formed at the lower end of the locking plate 18 to move the locking plate 18 from the restrained position. The lower end of the open lever 60 for swinging to the release position is pivotally attached.

The upper end of the open lever 60 abuts against the abutted portion 18a when the locking plate 18 swings to the abutting position, and hits when the locking plate 18 swings to the separated position. An output part 61 is formed to be separated from the contact part 18a. The open lever 60 is urged by a spring member 62 in the direction of swinging to the separated position.

At the center of the open lever 60 in the vertical direction, when the striker base 40 swings from the retracted end position to the retracted start position, the output lever 55 swings to the contact position. An input portion 63 is formed to which the rotational force of is input via the cam follower 56. The input portion 63 is extended to one end of the cam groove 41 so as to be pushed when the cam follower 56 moves to one end of the cam groove 41.

In the open lever 60, the trunk lid 10 is forcibly operated to make a small opening operation via the locking plate 18 to form a clearance for holding between the trunk lid 10 and the peripheral edge portion 12 of the trunk opening 11. A protruding portion 65 for forming is formed. The protruding portion 65 further moves the contacted portion 18a of the locking plate 18 upward after the open lever 60 contacts the contacted portion 18a of the locking plate 18 to swing the locking plate 18 to the release position. In order to project, the output portion 61 is continuously curved upward, and the contacted portion 18a of the locking plate 18 is formed so as to relatively slide.

As shown in FIG. 1, an input shaft 57 is implanted in the center of the output arm 55. A key portion 58 is formed at one end of the input shaft portion 57, and the key portion 58 penetrates the motor base 30 and projects toward the power portion 70 fixed to the front surface side of the motor base 30.

As shown in FIGS. 1 and 3 to 7, a drive motor 75 and a speed reducer 80 are housed in a housing 71 of the power unit 70. The drive motor 75 is horizontally placed with its motor shaft extending in both directions. An output worm 76 of the drive motor 75 meshes with an output spur gear 83 via two idle gears 81 and 82.

As shown in FIGS. 3 and 7 to 11, on the back side of the output spur gear 83, a circumferential cam groove 84 eccentric from the rotation center of the output spur gear 83 is formed. Has been done. A rotary switch 78 is accommodated in the housing 71, and a tip end portion of a switch lever 79 of the rotary switch 78 is movably fitted along a circumferential cam groove 84.

As shown in FIGS. 6 and 12 to 17, on the surface side of the output spur gear 83, the output spur gear 83 can be relatively moved and adjusted in the radial direction of the output spur gear 83, and A disk-shaped relay member 90 is housed so as to be immovable in the circumferential direction of the spur gear 83. A locking projection 91 is bent around the periphery of the relay member 90, and a damper member 92 is fitted on the locking projection 91.

A circular storage groove 85 having a diameter slightly larger than the diameter of the output spur gear 83 is formed on the front surface side of the output spur gear 83. An engaging groove 86, which is deeper than the accommodating groove 85, is formed in a part of the accommodating groove 85, and a damper member 92 is fitted in the engaging groove 86.

A central shaft portion 93 is provided at the center of the relay member 90, and a key groove 94 into which the key portion 58 of the input shaft portion 57 is relatively non-rotatably fitted is formed in the central shaft portion 93. Has been formed.

Next, the operation will be described. In this device, the housing 71 of the power unit 70 accommodates the drive motor 75 and the speed reducer 80, the housing 71 also accommodates the rotary switch 78, and the output spur gear 83 When rotated, the switch lever 79 of the rotary switch 78 moves along the circumferential cam groove 84, and the rotational position of the output spur gear 83 can be detected by the swing motion of the switch lever 79. .

Therefore, for example, it is not necessary to fixedly install a cam member for detecting a rotational position on the rotation center axis of the output spur gear 83, and it is not necessary to provide a limit switch or the like in connection therewith. The entire apparatus does not become bulky in the axial direction of the rotation center axis of the spur gear 83 for use.

Further, since the relay member 90 is housed in the surface portion of the output spur gear 83, the relay member 90 does not become bulky in the axial direction of the rotation center axis of the output spur gear 83, and the device As a whole, it does not become bulky in the axial direction of the rotation center axis of the output spur gear 83.

Further, since the relay member 90 is housed so as to be relatively movable and adjustable in the radial direction of the spur gear 83 for output, when the housing 71 is mounted, there is variation in the mounting position. Even if the key groove 94 of the central shaft portion 93 on the member 90 side does not correspond to the key portion 58 of the input shaft portion 57 on the retracting mechanism 50 side, as shown in FIGS. By moving and adjusting 90 in the storage groove 85 in the radial direction of the spur gear 83 for output, the key groove 94 and the key portion 58 can be easily made to correspond to each other, and the key portion 58 can be attached to the key groove 94. It can be fitted non-rotatably.

When the output spur gear 83 is rotated by the drive motor 75, the relay member 90 rotates integrally with the output spur gear 83, and the pull-in mechanism is inserted through the key groove 94 and the key portion 58. The power of the drive motor 75 can be transmitted to the input shaft portion 57 on the 50 side.

In the state where the trunk lid 10 is open, the striker base 40 is raised and is in the retracted start position, as shown in FIG. At this time, the switch lever 79 of the rotary switch 78 is in the state shown in FIG. 9, for example.

When the trunk lid 10 is closed, the latch member 17 engages with the striker 45, the locking plate 18 engages with the latch member 17, and the latch member 17 is restrained in the engaged state. It

When the latch member 17 is engaged with the striker 45, the rotation of the drive motor 75 causes the output spur gear 83 to rotate via the output worm 76 to the idle gears 81 and 82, and the output spur gear 83 When is rotated, the relay member 90 is integrally rotated, the output arm 55 is rotated through the center shaft portion 93 to the input shaft portion 57, and the retracting mechanism 50 is operated.

When the output arm 55 rotates, the cam follower 56 of the output arm 55 is located at an intermediate position between one end and the other end of the cam groove 41 of the striker base 40, and as shown in FIGS. It moves in the groove of the cam groove 41 of the striker base 40 toward the other end.

At this time, the cam follower 56 oscillates at a relatively large oscillating angle with respect to the length of movement within the cam groove 41, and, for example, with one end of the striker base 40 at the center, The other end of the striker base 40 can be pulled down.

As shown in FIG. 27, the state at this time is that of the present embodiment, as compared with the case where the cam groove 41 has a linear shape (the pulling force F ₂ corresponding to the pulling amount is represented by a broken line). In the case of the arc shape (the pulling force F ₂ corresponding to the pulling amount is represented by a solid line), the pulling force of the pulling mechanism 50 is smaller. Thereby, for example, even if a hand is accidentally caught in the gap between the trunk lid 10 and the peripheral portion 12 of the trunk opening 11, the hand can be easily pulled out and it is safe.

Further, when the output arm 55 rotates and the cam follower 56 moves in the groove of the cam groove 41 of the striker base 40 from the other end toward one end, as shown in FIGS. 22 to 23, The striker base 40 swings, the striker 45 pulls in the latch member 17, and the trunk lid 10 is closed. Eventually, the switch lever 79 of the rotary switch 78 goes through the state shown in FIG. Then, the drive motor 75 is stopped, and the trunk opening 11 is completely closed back and forth.

The state at this time, like, as shown in FIG. 27, the cam groove 41 is reversed retraction force F ₂ in the case were arc shape from retraction force F ₂ when the Tsu Der linear shape At the end of the pull-in shown in FIG. 23, the pull-in force F ₂ becomes very large. As a result, for example, even when the restoring force of the weather strip (not shown) provided along the peripheral edge portion 12 of the trunk opening 11 is large, it can be counteracted, and the weather strip is bent, The trunk lid 10 can be completely closed.

[0044] Also, in FIGS. 25 and 26, respectively and pull inclusive force F ₂ when the cam groove 41 is a straight line shape, retraction force when the an arc shape F ₂ and the.

When the striker base 40 is swinging from the retracting start position shown in FIG. 21 to the retracting end position shown in FIG. 23, the open lever 60 is in the separated position, and the cam follower 56 is the input of the open lever 60. The output portion 61 is retracted from the portion 63 and is separated from the contacted portion 18a of the locking plate 18.

When the trunk lid 10 is completely closed, the output arm 55 may be rotated by power to open the trunk lid 10.

The output arm 55 rotates, the cam follower 56 moves toward the one end in the cam groove 41, and the striker base 40 swings from the retracted end position shown in FIG. 23 to the retracted start position shown in FIG. Move.

Further, when the cam follower 56 moves toward the one end in the cam groove 41, as shown in FIG. 24, the cam follower 56 eventually pushes the input portion 63 of the open lever 60, and the open lever 60 abuts. As the output portion 61 of the open lever 60 abuts against the abutted portion 18a of the locking plate 18, the locking plate 18 swings to the release position, and the latch member 17 is disengaged from the striker 45. Become.

Further, when the output arm 55 rotates and the cam follower 56 moves in the cam groove 41 from one end to the other end, the upper end of the open lever 60 is moved as shown by the imaginary line in FIG. As a result, the contacted portion 18a of the locking plate 18 moves relatively from the output portion 61 of the open lever 60 to the protruding portion 65, whereby the contacted portion 18a of the locking plate 18 moves. It is projected upward.

As a result, for example, even when the trunk lid 10 is heavier than usual under snow, or the trunk lid 10 is difficult to open due to freezing, the trunk lid 10 is forcibly opened slightly upward. At this time, a hand-held gap is formed between the trunk lid 10 and the peripheral portion 12 of the trunk opening 11, and the trunk lid 10 can be easily opened by inserting a hand into the hand-held gap.

When the output arm 55 further rotates, the cam follower 56 returns from one end of the cam groove 41 to the intermediate position, and the switch lever 79 of the rotary switch 78 returns to the state shown in FIG. 9 through the state shown in FIG. The drive motor 75 stops, and the stroker base 40 returns to the initial retracting start position in the forward and backward directions.

[0052]
