Description

[Detailed Description of the Invention] The present invention relates to a mounting mechanism for a back door lock control device, and more specifically, a mounting mechanism for a back door lock control device. This invention relates to a back lock control device that greatly increases the degree of freedom of adjustment.

Until now, automobile back door lock control devices have been modified to fix the mounting board of the lock control device, for example, as described in Japanese Utility Model Application No. 55-1534, because it is relatively easy to maintain the appearance of the back door. All lock control devices are provided on the inner plate side of the back door, and the lock control device is fixed to the inner plate of the back door via a fastening member such as a grommet screw. According to such a conventional lock control device mounting mechanism, the inside handle attached to the back door can always occupy a fixed relative position with respect to the lock control device, making it easy to install the back door lock control device. In this case, there is no need to take special consideration regarding the relative positional adjustment between the base plate of the lock control device and the rotating shaft of the inner handle. On the other hand, this lock control device mounting mechanism cannot adjust the relative position of the outer handle attached to the area blocked by the license lamp on the outside of the back door, the rotation axis of the outer handle, and the lock control device. Therefore, depending on the dimensional tolerances and assembly tolerances of the parts that make up the lock control device, when installing the lock control device, it is necessary to find a good relative assembly position between the outer handle and its rotating shaft and the lock control device. It is not easy to secure it, and in extreme cases, when installing the outer handle, the position of the rotation axis does not match the position of the rotation shaft insertion hole drilled in the outer plate, and as a result, the inner handle and its rotation axis are Requires reassembly of the entire back lock control device, etc.
It was recognized that there were obstacles to improving productivity on the car body assembly line that could not be overlooked.

The main object of the present invention is to provide a new lock control device mounting mechanism that solves the above-mentioned problems found in conventional back lock control device mounting mechanisms.

The object of the present invention is to arrange a board for supporting a back lock control device between an outer panel and an inner panel, and to attach a first fixing portion to the outer panel and a second fixing portion to the inner panel to the substrate. A fixed part is formed on the inner plate, and the back lock control device is fixed to the outer plate using the first fixing part, and then a relative fixation between the base plate and the inner plate is formed. Advantageously achieved by employing a mounting mechanism for a back lock control device in which a fastening member insertion hole having a diameter larger than that of the board fastening member is bored to enable adjustment of the position. Can be done.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 is a perspective view of the board used in the mounting mechanism for the back lock control device according to the present invention, viewed from the passenger compartment side, and Fig. 2 explains the operating state of the back lock control device using the above board.

These fixing parts 1, 2, and 3 have fastening member insertion holes 1', 2', and 3' for fixing the board A to the outer plate and inner plate through conventional fastening members such as gross met screws. 3' is drilled. In the present invention, the width L between the outer surface of the first fixing part 1 to the outer panel and the outer surface of the second fixing parts 2 and 3 to the inner panel is the distance between the outer panel and the inner panel of the back door. The first fixing portion 1 is provided with a fastening member insertion hole 1' having a diameter substantially equal to the outer diameter of the fastening member. On the other hand, the fastening member insertion holes 2' and 3' formed in the second fixing parts 2 and 3 relative to the inner plate allow the back lock control device to be attached to the outer plate by using the first fixing part 1. The fastening member is formed to have a larger diameter than the outer diameter of the fastening member in order to make it possible to adjust the relative fixing position between the board A and the inner plate after they are fixed.

FIG. 2 is a front view illustrating the operating state of the back door lock control device incorporated in the board A, and is shown as viewed from the outside of the vehicle interior, contrary to FIG. 1. 1 and 2, the first swing lever 6 is swingably attached to the board A via a coiled return spring 7 and a stud 7', and has an inside handle at one end. A connecting part 16 with a lever (not shown) extending from the outside handle is formed, and a pressing part 9 is formed at the other end by a lever 9' with a pressing member extending from the outside handle. The first swing lever 6
When the back door is opened and closed, the stud 7' swings from side to side in a plane parallel to the plane of the paper with the axis 4 of the stud 7' as the center of rotation, and the connection part with the lever extending from the inside handle 16, an L-shaped first through groove 8 is formed. The second swing lever 11, like the first swing lever 6, swings left and right on a plane parallel to the plane of the paper with the axis 4 of the stud 7' as the center of rotation of the swing movement. It is attached to the base plate A via a tension spring 10 so as to cooperate with the first swing lever 6 . A second through groove 13 that extends radially toward the axis 4 is provided at one end of the second swing lever 11 . The L-shaped first through groove 8 and second through groove 13 are formed along the groove wall surface within these through grooves when the first swing lever 6 and the second swing lever 11 work together. Pin 14 with a flange or stop spring that can be moved by
connected by. Further, the other end of the second swing lever 11 is provided with a hole 20 into which the end of the first connecting rod that operates the back door lock assembly when opening and closing the back door is inserted. Note that the relative positions of the first swing lever 6 and the second swing lever 11 in FIG. 2 are shown with the back door locked.

Above the axis 4 of the stud 7', a third swinging lever 15 is connected to the stud 5 and has a connecting portion to a second connecting rod 18 extending from the inner lock knob and a third connecting rod 17 extending from a key cylinder (not shown). It is attached to the substrate A so as to be able to swing from side to side in a plane parallel to the plane of the paper, with the center of rotation being the center of rotation for the swing movement. The third swing lever 15 in FIG. 2 is shown relative to the first and second swing levers 6 and 11 as being in an unlocked state. A third through groove 19 having a radius of curvature centered around the axis 4 of the stud 7' is provided at the lower end of the third swinging lever 15. This maintains the connection relationship between the first through groove 8 and the second through groove 13.

For the back door, press the inside lock knob and displace the second connecting rod 18 downward as shown in Figure 2, or move the third connecting rod 17 extending from the key cylinder to the right by operating the door opening/closing key. It is switched to the locked state by That is, the third swinging lever 15 connects these connecting rods by displacement of the connecting rods 17 and 18.
pivots clockwise about the stud 5, and as a result, the pin 14, which is slidably fitted in the first to third through grooves 8, 13 and 19, is moved to the lower end of the third through groove 19. While moving towards the upper end 13' of the second through groove 13 and the L-shaped corner of the first through groove 8, the back door is switched to the locked state. In this state, even if the first swinging lever 6 is given a swinging motion about the axis 4 of the stud 7' to displace the connecting part 16 or the pressing part 9, the pin 14 The second swing lever 11 is moved only by relative movement toward the bottom end 8' of the arcuate groove whose radius of curvature is centered around the axis 4, which is wider than the radial groove of the through groove 8. A clockwise rocking motion about the axis 4 as the center of rotation is not transmitted to. Therefore, the first connecting rod fitted into the hole 20 of the second swing lever 11 is not displaced and the back door lock assembly is maintained in the locked state. On the other hand, when the first swing lever 6 is rocked clockwise when the third swing lever 15 is in the unlocked position shown by the solid line in FIG. The pin 14 located at the bottom 8'' in the radial direction presses against the side wall surface of the through groove 13 of the second swing lever 11 at the bottom 13'' of the through groove 13 of the second swing lever 11. As a result, the second swing lever 11
The lever swings clockwise about the axis 4 to displace the first connecting rod fitted into the hole 20 of the lever downward, thereby releasing the locked state of the back door lock assembly 12 shown in FIG. 3. .

First, the mounting reference of the back lock control device is set on the outer plate side, and the first fixing part 1 of the board A is secured using a conventional fastening member such as a grommet screw inserted into the fastening member insertion hole 1'. It is temporarily attached to the outer panel (not shown), and then the outer handle operating member extending toward the back lock control device from an appropriate position such as below the license lamp on the outer panel is aligned with the through hole drilled in the outer panel. In this state, the first fixing portion 1 is fixed to the outer panel. Next, the substrate A is fixed to an inner plate (not shown) using second fixing parts 2 and 3 having fastening member insertion holes 2' and 3' having a diameter larger than that of the fastening member. Since the fastening member insertion holes 2' and 3' of the second fixing part have a sufficient fitting gap for the diameter of the fastening member inserted into the holes, the first fixing part 1 can be attached to the outer plate. Even after fixing, an adjustable fixing area necessary for positioning the substrate A can remain between the second fixing part and the inner plate. FIG. 3 is a perspective view illustrating the overall structure of the back door lock control device installed between the outer panel and the inner panel of the back door. A first swing lever that swings in conjunction with the outside handle, a second swing lever that swings in conjunction with the back door lock assembly when opening and closing the door, and a second swing lever that swings in conjunction with the key cylinder and inside lock knob. A third swinging lever that moves is supported by the first and second swinging levers coaxially, and each of the first, second, and third swinging levers maintains a mutual connection relationship. A board is arranged between the outer panel and the inner panel, and a first fixing part to the outer panel and a second fixing part to the inner panel are attached to the board so that the dimension between both sides of both fixing parts is the outside of the back door. The second fixing part is provided so as to substantially match the interval between the board and the inner board, and the relative fixing position between the board fixed to the outer board and the inner board can be adjusted at the first fixing part. In order to do this, the fastening member insertion hole is provided with a sufficient fitting gap for the diameter of the board fastening member, so after fixing the board to the outer panel,
The adjustable fixing area can be used to fix the substrate to the inner plate.
