Description
Technical Field
[0001] This invention belongs to the field of automotive rearview mirror ground light detection technology, and specifically relates to an automotive ground light detection fixture. Background Technology
[0002] With the continuous advancement of automobile manufacturing technology, automobiles are becoming increasingly sophisticated. In recent years, puddle lights have been installed on the rearview mirrors of automobiles to provide illumination to the ground around the car in low-light conditions. This makes it easier for drivers to get in and out of the car or to better understand the road conditions around the car while driving, thus avoiding danger. The patterns projected onto the ground by the puddle lights not only bring convenience to customers but also display a high-tech and cool feel.
[0003] Most rearview mirror manufacturers cannot simulate the coordinates of the entire vehicle; they can only test the functionality of the puddle lights by projecting a scaled image. This cannot fully verify the conformity between the actual projected pattern and the theoretical data. If the puddle light's installation position is off, it will cause a significant deviation in the projected image, affecting the user experience. Furthermore, once the puddle light is installed on the lower housing of the rearview mirror, it cannot be returned for repair, resulting in high claims costs.
[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

The base plate bracket has a pair of symmetrically distributed support mechanisms. The V-shaped block is mounted on the support mechanisms. A door outer panel simulation block is mounted on the outer wall of the V-shaped block. An installation slot is formed on the door outer panel simulation block. A set of rearview mirror mounting holes is provided on the V-shaped block. An integrated rearview mirror is placed within the installation slot and mounted on the outer wall of the V-shaped block through the rearview mirror mounting holes. A puddle light is provided at the bottom of the integrated rearview mirror. A set of support rods is provided on the base plate bracket. A projection plate is mounted on the support rods. Support plates are fixed to the four outer corners of the base plate bracket. Reinforcing ribs are fixed to the four inner corners of the base plate bracket.
[0006] Furthermore, a set of insertion posts are fixedly connected to the side wall of the simulated block of the outer door panel; an insertion hole is opened on the side wall of the V-shaped block; the insertion post is inserted into the insertion hole; and a first nut is threaded to the end of the insertion post.

[0009] Furthermore, a second hydraulic cylinder is fixedly connected to the side wall of the upper movable block; the output end of the second hydraulic cylinder is provided with a second hydraulic rod, and the end of the second hydraulic rod passes through the upper movable block and is fixedly connected to a placement block; the V-shaped block is installed on the top of the placement block.
[0010] Furthermore, a set of elongated through holes are provided on the mounting surface of the V-shaped block; the V-shaped block is threaded onto the top of the placement block by passing through the elongated through holes with a first bolt; during operation, it is convenient to handle the inspection operation of different vehicle door panels, and the operation of the first bolt and elongated through holes allows for quick replacement.
[0011] Furthermore, a guide block is fixed to the side wall of the placement block; the guide block passes through the upper moving block, and the top view of the guide block is T-shaped.

[0021] The following description provides many different embodiments or examples for implementing various features of the invention. The elements and arrangements described in the specific examples below are only for concise expression of the invention and are merely examples, not intended to limit the invention.
[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] like Figure 1 and 2As shown, the present invention provides a vehicle puddle light testing fixture, including a V-shaped block 12, a door outer panel simulation block 1, and a base plate bracket 16; the base plate bracket 16 is provided with a pair of symmetrically distributed support mechanisms; the V-shaped block 12 is mounted on the support mechanisms; the door outer panel simulation block 1 is mounted on the outer side wall of the V-shaped block 12; the door outer panel simulation block 1 has a mounting slot 11; the V-shaped block 12 has a set of rearview mirror mounting holes 13; an integrated rearview mirror is placed in the mounting slot 11. The integrated rearview mirror 14 is mounted on the outer wall of the V-shaped block 12 through the rearview mirror mounting hole 13; a ground light 15 is provided at the bottom of the integrated rearview mirror 14; a set of support rods 17 are provided on the base plate bracket 16; a projection plate 18 is mounted on the support rods 17; support plates 19 are fixedly connected to the four outer corners of the base plate bracket 16; reinforcing ribs 191 are fixedly connected to the four inner corners of the base plate bracket 16; during operation, the door outer panel simulation block 1 is first installed on the V-shaped block 12, and then the V-shaped block 12 is installed on the V-shaped block 12. The V-shaped block 12 is installed on the support mechanism. The support mechanism, the base plate bracket 16, the V-shaped block 12, and the door outer panel simulation block 1 form a testing fixture that simulates the coordinates of the whole vehicle. At the same time, the integrated rearview mirror 14 is fixed on the door outer panel simulation block 1. Since the door outer panel simulation block 1 is a cut-out of the area where the rearview mirror is installed on the door outer panel of the vehicle body (1:1 scale), it is also the installation point of the integrated rearview mirror 14. Using the door outer panel simulation block 1 to replace the door outer panel of the vehicle body can effectively save tooling costs. When testing is required, the installed integrated rearview mirror 14 and the ground light 15 are opened. After the integrated rearview mirror 14 is in a preset flip angle, the light pattern of the ground light 15 is projected onto the projection plate 18. The clarity of the projection pattern can be clearly observed, and it can be accurately seen whether the light pattern is parallel to the door outer panel of the vehicle body. It can also be effectively judged whether the door outer panel of the vehicle body affects the projection effect of the pattern. While ensuring clarity, parallelism with the vehicle body, and projection integrity, it can quickly assist the testing personnel in the testing process.
[0024] like Figure 5-8 As shown, a set of insertion posts 2 are fixedly connected to the side wall of the simulated block 1 of the door outer panel; an insertion hole 21 is opened on the side wall of the V-shaped block 12; the insertion post 2 is inserted into the insertion hole 21; a first nut 22 is threadedly connected to the end of the insertion post 2; a cable hole 24 is opened in the middle of the outer side wall of the V-shaped block 12; a positioning hole 23 is fixedly connected to the side wall of the V-shaped block 12; a positioning post 27 is provided on the mounting surface of the integrated rearview mirror 14; During installation, to ensure ease of installation, the door panel simulation block 1 is inserted into the insertion hole 21 via the insertion post 2. For stability, a second fixing operation is performed using the first nut 22. When the integrated rearview mirror 14 is inserted into the mounting slot 11, the positioning post 27 is first inserted into the positioning hole 23 for guidance and limitation. Then, the integrated rearview mirror 14 is fixed through the rearview mirror mounting hole 13 (the fixing can be done using bolts, clips, or other methods, depending on the structure of the corresponding integrated rearview mirror 14). Finally, the power connector is inserted into the integrated rearview mirror through the cable hole 24. At the power-on point of mirror 14, the installation and power-on operation of integrated rearview mirror 14 is completed. Installation and disassembly are simple and convenient. V-shaped block 12 and door outer panel simulation block 1 can be replaced with different types to correspond to the body door outer panel structure of different vehicles (one body door outer panel corresponds to one door outer panel simulation block 1, and also corresponds to one integrated rearview mirror 14). The other structures of the tooling are used to facilitate the detection of ground light 15 on integrated rearview mirrors 14 of multiple vehicles. The support structure setting can facilitate the adjustment of the position coordinates of door outer panel simulation block 1. The above-mentioned pair of integrated rearview mirrors 14 are symmetrically arranged as the left and right integrated rearview mirrors 14 of the vehicle.
[0025] At the same time, when working, the outline of the pattern can be drawn on the projection board 18 and the projection line of the outermost protrusion of the vehicle body door panel can be drawn, which can more clearly help the inspectors to judge whether the pattern is tilted or whether the light pattern is projected on the vehicle body door panel.
[0026] The support mechanism described in 2 and 3 includes a U-shaped block 3; a pair of symmetrically distributed U-shaped blocks 3 are provided on the base plate bracket 16; insertion slots 32 are provided on both ends of the U-shaped blocks 3; insertion rods 33 are slidably connected in the insertion slots 32; an upper moving block 31 is fixedly connected to the top of the pair of insertion rods 33; a first hydraulic cylinder 34 is fixedly connected to the bottom of the middle part of the U-shaped block 3; a first hydraulic rod 35 is provided at the output end of the first hydraulic cylinder 34; the end of the first hydraulic rod 35 is fixedly connected to the bottom end of the upper moving block 31; a second hydraulic cylinder 36 is fixedly connected to the side wall of the upper moving block 31; a second hydraulic rod 37 is provided at the output end of the second hydraulic cylinder 36, and the end of the second hydraulic rod 37 is... The upper moving block 31 is connected to a placement block 38; the V-shaped block 12 is installed on the top of the placement block 38; a guide block 39 is fixed to the side wall of the placement block 38; the guide block 39 passes through the upper moving block 31, and the top view of the guide block 39 is T-shaped; a pair of symmetrically distributed first sliding grooves 4 are provided on the base plate support 16; the bottom end of the U-shaped block 3 is slidably connected in the first sliding groove 4; a first lead screw 41 is rotatably connected in the first sliding groove 4; a servo motor 42 is fixed to the outer side wall of the base plate support 16 through a support plate 19, and the servo motor 42 drives the first lead screw 41 to rotate; the U-shaped block 3 is connected to the first lead screw 41 through a lead screw nut pair; Figure 4 As shown, the projection panel 18 is provided with a pair of projection display areas 5; the outer wall of the door panel simulation block 1 is provided with a set of position sensors 51; During operation, a projection display area 5 is provided on the projection board 18, and a position sensor 51 is provided on the door outer panel simulation block 1. The projection display area 5 directly projects a 3D projection (1:1 scale) of the vehicle body door outer panel to be detected. A set of position sensors 51 is provided in the door outer panel simulation block 1, and the position coordinates of the position sensors 51 correspond to the marked position coordinates on the 3D projection of the vehicle body door outer panel. During operation, the first hydraulic cylinder 34 moves the upper moving block 31 upward, and at the same time drives the placement block 38, V-shaped block 12 and door outer panel simulation block 1 to move upward to confirm the height position coordinates. Then, by setting the servo motor 42 and the second hydraulic cylinder 36, the position coordinates in the other two directions are confirmed until the position sensor 51 of the door outer panel simulation block 1 and the corresponding vehicle body door are aligned. The position of the simulated block 1 of the door panel is determined when the marked position of the 3D projection of the outer panel coincides. Then, the integrated rearview mirror 14 and the ground light 15 are charged and operated to determine the parallelism of the light pattern of the ground light 15 with the vehicle body door panel, the clarity of the light pattern, and whether there is any interference with the vehicle body door panel. The projection display area 5 can reduce the waste of physical materials, and the projection display area 5 allows the inspectors to observe and process more intuitively. It can also further accurately determine the position of the simulated block 1 of the door panel. If the position sensor 51 cannot coincide with the standard position of the 3D projection of the vehicle body door panel, it indicates that the position of the simulated block 1 of the door panel has been moved incorrectly or the shape of the simulated block 1 of the door panel has been manufactured incorrectly, causing errors, and replacement and adjustment are required. This further ensures the accuracy of the inspection (to inspect the left or right integrated rearview mirror 14, simply open the projection display area 5 on one side).
[0027] When in operation, this invention can not only detect the lighting pattern of the ground lamp 15 when the integrated rearview mirror 14 is opened at a preset angle, but also determine the opening angle of the integrated rearview mirror 14 when the lighting pattern of the ground lamp 15 is in a qualified state, which facilitates subsequent preset of the opening angle of the integrated rearview mirror 14.
[0028] like Figure 5 and 7 As shown, a set of elongated through holes 25 are provided on the mounting surface of the V-shaped block 12; the V-shaped block 12 is threaded onto the top of the placement block 38 by the first bolt 26 passing through the elongated through holes 25; during operation, it is convenient to handle the inspection operation of different vehicle door outer panels, and the operation of the first bolt 26 and the elongated through holes 25 can be quickly replaced.
[0029] like Figure 4As shown, a set of mounting holes 53 are provided on the projection plate 18; the projection plate 18 is threaded onto the support rod 17 by passing through the mounting holes 53 with the second bolt 52; during operation, it is convenient to replace the projection plate 18, avoiding the situation where the entire tooling is scrapped when the projection cloth 18 is partially damaged.
