Description

  The present invention is applied to a vehicle in which an electric actuator is operated to release the engagement between a latch device and a striker to open a door, and an operation for arbitrarily setting an open / close state of a door without using an electric actuator The present invention relates to an hour door holding device.

  As a latch device applied to a recent vehicle, there is provided a latch device that operates an electric actuator such as a motor to release a mesh with a striker when a door is opened. Although such a latch device can facilitate the operation when getting on and off the vehicle, it is difficult to open the closed door in a situation where power cannot be supplied. For example, when manufacturing a vehicle, it is common to mount an electrical component after a latch device and a striker are provided between the vehicle main body and a door. For this reason, when the latch device and the striker are engaged with each other before the electrical component is mounted, it is difficult to release the latch device and the manufacturing operation may be hindered.

  For this reason, conventionally, a closing member is provided that is mounted in an entry groove into which a striker enters in the latch device. In other words, by installing a closing member in the entrance groove in advance, a situation where the latch device and the striker mesh with each other is prevented in the vehicle manufacturing stage (see, for example, Patent Document 1).

  However, when the closing member is applied, the latch device cannot naturally be engaged with the striker, so that the door cannot be kept open with respect to the vehicle body. There is a risk that manufacturing operations may be hindered by wide opening.

  On the other hand, a conventional latch device provided with an operation string for operating from the outside is also provided. That is, even before the electrical component is mounted, the latch device and the striker can be released from the meshed state by operating the operation string drawn to the outside (for example, Patent Document 2). When such a latch device is applied, it is possible to open the closed door by operating the operation string even at the manufacturing stage of the vehicle, and the open / closed state of the door with respect to the vehicle body can be arbitrarily set.

  Exemplary embodiments of a working door holding device according to the present invention will be explained below in detail with reference to the accompanying drawings.

  1 and 2 show a working door holding apparatus according to an embodiment of the present invention. The working door holding device exemplified here is intended to be applied to a vehicle in which a back door D can be opened and closed at a rear end opening of a vehicle main body B as shown in FIGS. 4 and 5. . The back door D opens and closes the rear end opening of the vehicle main body B by rotating around the axis extending along the left-right direction at the upper edge of the rear end of the vehicle main body B.

  In this vehicle, the striker S is provided on the vehicle body B, while the latch device LA is provided on the back door D. When the back door D is closed with respect to the vehicle body B, the striker S and the latch device LA are provided. The vehicle is engaged with each other so that the back door D is kept closed with respect to the vehicle body B.

  The striker S was formed in a U shape by curving a metal rod-shaped member having a uniform outer diameter, as shown in FIGS. 5 and 6A and 6B. Therefore, both end portions of the columnar portions extending in parallel with each other are held by the striker base SB. The striker S is fixedly installed on the lower edge of the rear end of the vehicle body B via the striker base SB in a state in which columnar portions extending in parallel with each other are arranged in parallel in the front-rear direction with respect to the vehicle body B. is there. In the striker S, only the columnar portion located on the rear side of the vehicle main body B among the columnar portions extending in parallel with each other meshes with the latch device LA described later. For this reason, in the following, the portion disposed on the rear side of the vehicle main body B that meshes with the latch device LA will be specifically referred to as a striker rod SR.

  The latch device LA includes a latch base LB and a latch LL and a ratchet LR. The latch base LB extends from the lower end edge of the back door D so as to gradually incline toward the front of the vehicle. The latch base LB has an entrance groove AB at the extended end and is formed at both side edges of the latch base LB. Each has a side wall SW. The entrance groove AB is a notch formed from the center of the leading edge of the latch base LB toward the base end, and is formed to have a size capable of accommodating the striker rod SR. The side wall portions SW are portions erected substantially at right angles from both side edges of the latch base LB in the same direction, and extend substantially parallel to each other along the extending direction of the entry groove AB.

  The latch LL and the ratchet LR are rotatably disposed on the latch base LB via shaft members LLa and LRa, respectively. The configurations of the latch LL and the ratchet LR are the same as those of the conventional latch device LA. That is, when the striker rod SR enters the entry groove AB of the latch base LB from the state shown in FIG. 6 (a), the striker rod SR enters the engagement groove LLb of the latch LL, and then follows the entry of the striker rod SR. The latch LL rotates clockwise in FIG. 6 against the spring force of a return spring (not shown). During this time, the ratchet LR pressed against the peripheral surface of the latch LL by the spring force of the ratchet spring (not shown) advances into the engagement groove LLb of the latch LL as shown in FIG. The rod SR is maintained in mesh with each other, and the counterclockwise rotation of the latch LL in FIG. 6 is restricted. As a result, the striker rod SR is prevented from moving away from the entry groove AB, and the back door D is kept closed with respect to the vehicle body B.

  The latch device LA includes an electric actuator MA. The electric actuator MA is driven when power is supplied, and rotates the ratchet LR counterclockwise in FIG. 6 against the spring force of a ratchet spring (not shown). When the ratchet LR is rotated counterclockwise from the state shown in FIG. 6B, the engagement state between the latch LL and the ratchet LR is released, and the latch LL is rotated counterclockwise by the spring force of the return spring (not shown). Rotate to. As a result, the meshing state of the latch LL and the striker rod SR is released, and as shown in FIG. 6A, the striker rod SR may be deviated from the entry groove AB of the latch base LB to open the back door D. become able to.

  On the other hand, the working door holding device to which the vehicle described above is applied includes a first engagement member 20 and a second engagement member 30 in the apparatus main body 10 as shown in FIGS.

  The apparatus main body 10 has guide wall portions (guide means, positioning means) 12 on both sides of the base end portion of the main body base portion 11 formed to have a uniform width, and has an entry notch 13 at the distal end portion. . The guide wall portions 12 are provided with a gap between them that can accommodate the latch base LB of the latch device LA. When the latch base LB is disposed between the guide wall portions 12, the guide wall portion 12 comes into contact with the one side wall portion SW and the other side wall portion SW of the latch base LB, so On the other hand, the latch base LB can be slid along the extending direction of the guide wall portion 12, while the movement in the direction orthogonal to the guide wall portion 12 can be restricted. The entry notch 13 is a notch formed from the central portion of the front end surface of the apparatus main body 10 toward the base end portion, and is formed to have a size capable of accommodating the striker rod SR. Although not clearly shown in the drawing, the entry notch 13 opens at a position on the extension extension of the entry groove AB when the latch base LB is accommodated between the guide wall portions 12 in the apparatus main body 10. ing.

  The first engagement member 20 has a columnar shape having substantially the same outer diameter and the same length as the striker rod SR provided in the vehicle main body B, and is erected at a right angle from the surface of the main body base 11. is doing. The first engagement member 20 is disposed at a position corresponding to the entry groove AB of the latch base LB when the latch base LB is accommodated between the guide wall portions 12. As is clear from the figure, the upper end portion of the first engagement member 20 is provided with a reinforcing columnar portion 14 erected on the distal end side of the main body base 11 of the apparatus main body 10 with respect to the first engagement member 20. A connecting member 15 for connecting the two is provided.

  The second engaging member 30 is rotatably disposed on the apparatus main body 10 via a rotating shaft member 31 provided in a portion close to the reinforcing columnar portion 14, and includes a hook portion 32 and an operation linkage portion 33. I have.

  The hook portion 32 is a portion extending from the axial center of the rotating shaft member 31 in the radially outward direction. The hook portion 32 is provided with an engaging claw 34 at an extended end portion. As shown in FIG. 2, the engaging claw 34 rotates the second engaging member 30 counterclockwise, and the hook portion 32 is disposed at a position along the entry notch 13 toward the front end side of the apparatus main body 10. When it is done (meshing position), it is a portion that protrudes from the side surface close to the entry notch 13 at the tip thereof so as to face the entry notch 13. When the second engagement member 30 is rotated clockwise in FIG. 2, the engagement claw 34 of the hook portion 32 can be moved backward with respect to the entry notch 13 (release position). An inclined surface 35 that gradually inclines outward toward the base end of the hook portion 32 is formed at the distal end portion of the engaging claw 34.

  Similar to the hook portion 32, the operation linkage portion 33 is a portion extending from the axis of the rotary shaft member 31 in the radially outward direction. When the hook portion 32 is disposed at the meshing position, the operation linking portion 33 extends from the rotary shaft member 31 toward the one guide wall portion 12, and is exposed to the outside through the insertion hole 16 formed in the guide wall portion 12. It is configured to protrude.

  A biasing spring (biasing means) 40 is interposed between the second engagement member 30 and the apparatus main body 10. The biasing spring 40 biases counterclockwise in FIG. 2 so that the hook portion 32 of the second engagement member 30 is always disposed at the meshing position. The hook portion 32 of the second engagement member 30 urged counterclockwise in FIG. 2 by the urging spring 40 comes into contact with the rotation restricting wall portion 17 provided in the main body base portion 11 of the apparatus main body 10. The meshing position described above is defined.

  Further, the operation door holding device is provided with an operation member 50 in the apparatus main body 10. As shown in FIG. 3, the operation member 50 includes a slide portion 51 formed to have a length larger than that between the guide wall portions 12 in the apparatus main body 10, and guide portions 52 provided at both ends of the slide portion 51. The apparatus main body 10 is disposed in a state in which the apparatus main body 10 is accommodated between the guide portions 52. As is clear from FIG. 3, a slide guide mechanism 60 is configured between the apparatus main body 10 and the guide portion 52 of the operation member 50. The slide guide mechanism 60 includes a rail portion 61 projecting from both sides of the base end portion of the apparatus main body 10 and a guide groove 62 formed at a meeting portion of each guide portion 52 with the slide portion 51. Thus, by inserting the rail portions 61 respectively corresponding to the guide grooves 62, the operation member 50 is slidably held without being dropped with respect to the apparatus main body 10. As shown in FIG. 2, the operation member 50 is linked to the operation linkage portion 33 of the second engagement member 30 via a link rod 70.

  When the working door holding device configured as described above is in a normal state, the second engagement member 30 is maintained in the meshing position by the spring force of the biasing spring 40 as shown in FIG. The nail | claw 34 will be in the state which most advanced with respect to the notch 13 for an entrance of the apparatus main body 10. FIG. In this state, the operation linking part 33 of the second engagement member 30 is positioned on the most distal side with respect to the apparatus main body 10, so that the operation member 50 linked via the link rod 70 is also the apparatus main body 10. Are arranged in a state of being positioned closest to the tip end side.

  From this state, for example, when the back door D is held closed with respect to the vehicle main body B before the electrical components are mounted in the vehicle manufacturing process, first, as shown in FIG. The latch base LB of the latch device LA protruding from the lower end portion of the door D is slid on the main body base 11 of the device main body 10, and the latch base LB is accommodated between the guide wall portions 12.

  At this time, as described above, since the guide wall portion 12 of the apparatus main body 10 is formed with a distance corresponding to the latch base LB, the side wall portion SW of the latch base LB contacts each inner wall surface. It will slide in the state. Moreover, the first engagement member 20 of the apparatus main body 10 has a columnar shape having substantially the same outer diameter and the same length as the striker rod SR, and further, the entry groove AB of the latch base LB. Is disposed at a position corresponding to. Accordingly, when the slide of the latch base LB progresses, the first engagement member 20 is guided to the entrance groove AB of the latch base LB as shown in FIG. 7-2. Thereafter, when the first engagement member 20 enters the engagement groove LLb of the latch LL, the latch LL and the ratchet LR operate appropriately, and the first engagement member 20 and the latch LL are maintained in an engaged state. become.

  Here, the operation until the first engaging member 20 and the latch LL are engaged with each other is merely to slide the latch base LB of the latch device LA on the main body base 11 of the device main body 10. That is, since the guide wall portion 12 of the apparatus body 10 functions as a guide means when the latch base LB is slid, simply sliding the latch base LB automatically causes the first engagement member 20 and the latch LL to automatically move. It can be in a meshed state.

  When the first engagement member 20 and the latch LL are engaged with each other, the movement of the apparatus main body 10 with respect to the latch base LB is prevented from moving off, so that the door holding device for operation is the latch base LB. Will be mounted on the extension. In this case, since the guide wall portion 12 of the apparatus main body 10 is held in contact with the side wall portion SW of the latch base LB, even if an external force such as vibration is applied to the back door D, the guide wall portion 12 is positioned on both sides. There is no fear of displacement, and the entry notch 13 formed in the apparatus main body 10 is positioned on the extension of the entry groove AB formed in the latch base LB.

  Accordingly, when the back door D to which the working door holding device is attached is closed with respect to the vehicle main body B, the vehicle main body B with respect to the entry notch 13 of the device main body 10 as shown in FIG. The striker rod SR attached to the slidable rod enters, and the striker rod SR comes into contact with the inclined surface 35 of the engaging claw 34 in the state where it has advanced into the entry notch 13.

  The second engaging member 30 in which the striker rod SR is in contact with the inclined surface 35 of the engaging claw 34 resists the spring force of the biasing spring 40 by the action of the inclined surface 35 as shown in FIG. Then, in FIG. 8, it will rotate clockwise, allowing further entry of the striker rod SR. When the striker rod SR advances and passes through the inclined surface 35 of the engagement claw 34, the second engagement member 30 is returned to the engagement position by the spring force of the urging spring 40. As a result, as shown in FIG. 8C, the engaging claw 34 meshes with the striker rod SR on the opening end side of the entry notch 13, and the striker rod SR is detached from the entry notch 13. Be blocked.

  In this state, the first engagement member 20 meshes with the latch device LA, and the second engagement member 30 meshes with the striker S, whereby the gap between the latch device LA and the striker rod SR is established via the device main body 10. They will be connected to each other. Therefore, although the back door D is slightly opened with respect to the vehicle main body B, it can be maintained in a state where it is not opened any more. Thereby, in the manufacturing process of the vehicle, it is possible to surely prevent the back door D from being opened carelessly, and there is no possibility of causing a situation that hinders the manufacturing work.

  On the other hand, when the above-described back door D is opened, a hand is inserted through the gap between the vehicle body B and the back door D as shown in FIG. 9-1 and exposed to the outside as shown in FIG. 10-1. When the operation member 50 is slid to the base end side of the apparatus main body 10, the hook portion 32 of the second engagement member 30 is moved from the state shown in FIG. 9-2 via the link rod 70 and the operation linkage portion 33 to the timepiece. Rotates around to the release position shown in FIG. Accordingly, when the back door D is pulled upward, the striker rod SR is deviated from the entry notch 13 of the apparatus main body 10, and the back door D can be opened with respect to the vehicle main body B.

  If the hand is released from the working door holding device after the back door D is opened, the second engaging member 30 is returned to the meshing position by the spring force of the biasing spring 40. Accordingly, when the back door D is closed again with respect to the vehicle main body B, as described above, the second engagement member 30 is appropriately rotated and meshed with the striker rod SR. D can be maintained in an unopened state, and thereafter, the open / closed state of the back door D with respect to the vehicle body B can be arbitrarily set.

  Further, when the manufacturing process proceeds and an electrical component is mounted on the vehicle main body B, the engagement state between the latch device LA and the first engagement member 20 is released by driving the electric actuator MA. It becomes possible to remove the working door holding device from LA. Therefore, in the subsequent manufacturing process, the open / closed state of the back door D relative to the vehicle main body B can be arbitrarily set by the engagement of the latch device LA and the striker rod SR. The working door holding device removed from the latch device LA can be applied to the next vehicle as it is if it is returned to the manufacturing process before the electrical component is mounted.

  As described above, when the work door holding device is applied, it is possible to arbitrarily set the open / closed state of the back door D with respect to the vehicle main body B without requiring complicated work. That is, for the latch device LA, the latch device LA and the first engagement member 20 can be engaged with each other by entering the first engagement member 20 into the entry groove AB of the latch base LB. With respect to the striker rod SR, if the striker rod SR enters the notch 13 for entering the apparatus main body 10, the striker rod SR and the second engagement member 30 can be brought into meshing state, and the apparatus main body 10 is The latch device LA and the striker rod SR can be connected via each other. On the other hand, when the operation member 50 exposed to the outside of the apparatus body 10 is operated, the meshing state between the striker rod SR and the second engagement member 30 can be released. Thereby, it becomes possible to arbitrarily set the open / closed state of the back door D with respect to the vehicle main body B, and the work on the vehicle can be made more efficient.

  Moreover, the work door holding device can be easily removed by releasing the meshed state with the latch device LA by driving the electric actuator MA at the time when the electrical component is mounted. Can be reused as is. Therefore, even when a large number of vehicles are manufactured, such as a vehicle manufacturing line, it is not necessary to prepare the working door holding devices corresponding to the number of vehicles to be manufactured. The larger the number of the more, the more the application cost can be reduced, and the influence on the manufacturing cost of the vehicle becomes extremely small.

  In the above-described embodiment, the one applied between the vehicle main body B and the back door D is exemplified. However, not only the back door D but also the engagement state of the latch device and the striker is determined by the operation of the electric actuator. It can be applied to other doors such as a trunk lid, a sliding door, a side door, etc. as long as it is to be released. Moreover, although the striker S is provided in the vehicle main body B and the vehicle in which the latch device LA is provided in the door is applied, the present invention can be applied even if the striker and the latch device are provided in the vehicle in the opposite mode.

  Further, in the above-described embodiment, the operation member 50 is slidably disposed on the apparatus main body 10. However, the operation member may be a lever-like one, a string, a belt-like one, or the like. Is not limited to the implementation. In short, any device can be applied as long as it can be operated from the outside of the apparatus main body.

  In the above-described embodiment, the second engagement member 30 is disposed so as to be rotatable with respect to the apparatus main body 10. However, the movement mode of the second engagement member is not necessarily limited to rotation. For example, it may be moved between the meshing position and the release position by linearly sliding with respect to the apparatus main body 10, or between the meshing position and the release position by being attached to and detached from the apparatus main body. You may make it move.
