[0023] It should be noted that in the present invention, the left - right direction, front - rear direction, and up - down direction correspond one by one to the front - rear direction, left - right direction, and up - down direction of the vehicle body.
[0024] Please refer to Figure 1 、 Figure 4 and Figure 5, the present invention provides a lateral stiffness test device for an automotive window regulator 2, which includes a test frame 1, a window regulator 2, a connection assembly 3, a simulated glass part 4, and a measuring mechanism 5. The test frame 1 is used to support on the ground; the window regulator 2 includes a guide rail 21, a glass bracket 22, and a drive structure 23. The guide rail 21 extends in the vertical direction and is installed on the test frame 1. The glass bracket 22 is located on the right side of the guide rail 21 and is formed with at least two sliding grooves 221. The two sliding grooves 221 are respectively slidably connected to the front and rear sides of the guide rail 21. The drive structure 23 is located on the left side of the guide rail 21 and is used to drive the glass bracket 22 to move up and down; the connection assembly 3 is installed on the test frame 1 and includes a connecting member 31 that moves in the front-rear direction; the simulated glass part 4 is fixedly connected to the glass bracket 22, and its upper end is rotatably installed on the connecting member 31 around an axis extending in the left-right direction; the measuring mechanism 5 includes a force sensor 51 provided at the rear side of the connecting member 31 and a displacement sensor 52 located at the front side of the simulated glass part 4 and arranged opposite to the force sensor 51.
[0025] An external force is applied to the force sensor 51, causing the force sensor 51 to move forward, driving the connecting member 31 to move forward and pushing the simulated glass part 4 to move forward. Since the guide rail 21 is slidably connected to the glass bracket 22, and there is a gap between the front groove wall or the rear groove wall of each sliding groove 221 and the corresponding front side or rear side of the guide rail 21, as the connecting member 31 continues to move forward, the glass bracket 22 moves forward until the rear side walls of the sliding grooves 221 located at the rear side abut against the rear side of the guide rail 21, and even causes the lower end of the simulated glass part 4 to rotate slightly backward. And during the movement stroke of the simulated glass part 4, the force sensor 51 always abuts against the rear side of the connecting member 31 to detect the real-time force received by the simulated glass part 4; the displacement sensor 52 always abuts against the front side of the simulated glass part 4 to detect the displacement data of the simulated glass part 4, so as to realize the displacement of the real vehicle simulated glass part 4 in the front-rear direction of the vehicle body when receiving the front-rear force of the vehicle body, and evaluate the strength of the window regulator 2 to maintain the front-rear running posture of the glass. In this way, the lateral stiffness test device of the automotive window regulator 2 only limits the left-right direction of the simulated glass part 4, and does not limit the rotation of the simulated glass part 4 in the front-rear direction, avoiding lack of limitation and over-limitation, ensuring the same installation state as the test drive, and improving the accuracy of the test results.
[0026] In addition, by swapping the positions of the force sensor 51 and the displacement sensor 52, the backward movement of the simulated glass part 4 is tested. The displacement of the simulated glass part 4 in the front-rear direction of the vehicle body when receiving the front-rear force.
[0027] Specifically, in this embodiment, refer toFigure 1 and Figure 6 An installation through-hole 41 extending in the left-right direction is provided at the upper end of the simulated glass member 4. The connecting member 31 includes a connecting block 311, a connecting bolt and a connecting nut. The connecting block 311 is provided with a connecting groove 3111 with a notch facing forward and through upper and lower groove walls, and two connecting through-holes 3112 respectively located on the left and right sides of the connecting groove 3111 and communicating with it. The groove width of the connecting groove 3111 is adapted to the thickness of the simulated glass member 4, and its rear groove wall abuts against the rear side surface of the simulated glass member 4; the connecting bolt passes through the installation through-hole 41 and the two connecting through-holes 3112; the connecting nut is screwed onto the connecting bolt, and the nut of the connecting bolt respectively abuts against the left and right side surfaces of the connecting block 311. Thus, the upper end of the simulated glass member 4 is rotatably connected to the connecting member 31, and the structure is simple and easy to set. And at least part of the upper end of the simulated glass member 4 is received in the receiving groove, and the rear side surface of the simulated glass member 4 abuts against the bottom wall of the connecting groove 3111, which is convenient for the connecting member 31 to push the simulated glass member 4.
[0028] Similarly, the installation of the connecting member 31 can also be adjusted so that the notch of the connecting groove 3111 faces backward to test the displacement of the simulated glass member 4 when a force acting backward on the vehicle body is applied.
[0029] More specifically, in this embodiment, referring to Figure 1 、 Figure 3 and Figure 7 The connecting member 31 further includes a guide sleeve 32. The guide sleeve 32 extends in the front-rear direction and is installed on the test stand 1; the connecting member 31 further includes a connecting rod 312. The connecting rod 312 passes through the guide sleeve 32 and is coaxially arranged with the guide sleeve 32. The front end of the connecting rod 312 is connected to the connecting block 311, and the rear end of the connecting rod 312 abuts against the force sensor 51. The inner hole of the guide sleeve 32 plays a guiding role, enabling the connecting rod 312 to always move in the front-rear direction, that is, the simulated glass member 4 is always subjected to a front-rear thrust force, ensuring the accuracy of the test structure. In this way, the structure is simple, easy to set, and convenient for disassembly, replacement.

[0031] In this embodiment, a plurality of mounting through holes 41 are provided, and the plurality of mounting through holes 41 are spaced apart in the up-and-down direction. The driving structure 23 drives the simulated glass member 4 to move up and down, so that different mounting through holes 41 correspond to the two connecting through holes 3112, and the simulated glass member 4 is connected to the connecting member 31 at different heights, so as to facilitate testing the displacement of the simulated glass member 4 when it is subjected to the front-back force of the vehicle body at different rising heights and collecting more test data.
[0032] It should be noted that the simulated glass member 4 has a central symmetry structure, and a plurality of the mounting through holes 41 are also provided at the lower end of the simulated glass member 4 and are spaced apart in the up-and-down direction.
[0033] Specifically, referring to Figure 1 and Figure 2 , the test rack 1 includes a bracket 11, a mounting plate 12 and at least three fixing brackets 13. The bracket 11 is used to be placed on the ground; the mounting plate 12 is mounted on the bracket 11 and is provided with a plurality of mounting holes distributed in a matrix. The plurality of mounting holes are for the selectively mounting of the lifter 2; thus, the lifter 2 can be flexibly mounted at any position of the test rack 1 through a plurality of bolts and is firmly connected. The three fixing brackets 13 are spaced apart in the front-back direction and mounted on the bracket 11, all extend in the left-right direction and are located above the mounting plate 12. Each of the three fixing brackets 13 is for mounting the displacement sensor 52, the connecting member 31 and the force sensor 51. Among them, the displacement sensor 52 and the guide sleeve 32 are both fixedly connected to the corresponding two fixing brackets 13, and the force sensor 51 is movably mounted along the front-back direction on the corresponding fixing bracket 13.
[0034] In addition, in this embodiment, a frame body 14 is further mounted on the left side surface of the mounting plate 12. The frame body 14 is for mounting the guide rail 21, so that the guide rail 21 is spaced apart from the left side surface of the mounting plate 12, so as to facilitate the installation of the glass bracket 22 and the driving structure 23 within the interval.
[0035] More specifically, in this embodiment, referring to Figure 1 , Figure 6 and Figure 7Each of the fixing frames 13 includes a fixing seat 131, an adapter 132 and a connecting plate 133. The fixing seat 131 is installed on the bracket 11 and is provided with a fixing hole 1311 extending in the front-to-back direction; the adapter 132 extends in the left-right direction, the right end of the adapter 132 is fixedly installed in the fixing hole 1311, and the left end of the adapter 132 is formed with a card slot 1321 penetrating in the front-to-back direction, and the card slot 1321 is adapted to the displacement sensor 52, the connecting member 31, or the force sensor 51; the displacement sensor 52 and the guide sleeve 32 are fixed in the card slot 1321, and the force sensor 51 is slidably installed in the card slot 1321, so that the force sensor 51 can only move in the front-to-back direction, the test is rigorous, and the error is reduced. The connecting plate 133 extends in the vertical direction, and its upper end is connected to the fixing seat 131 and is located on the right side of the bracket 11. The connecting plate 133 is provided with an elongated through slot 1331 that penetrates in the left-right direction and extends in the vertical direction. The elongated through slot 1331 can be selectively connected with the plurality of mounting holes. The elongated through slot 1331 and the mounting holes are connected by bolts and nuts matched with the bolts, and the elongated through slot 1331 can correspond to the plurality of mounting holes, so as to facilitate the rapid installation and removal of the fixing brackets 13 and the mounting plate 12, and facilitate the adjustment of the positions of the plurality of fixing seats 131 to switch the displacement test of the simulated glass member 4 when the vehicle body moves forward and backward.
[0036] In addition, the fixing frame 13 may be provided in pairs for fixing and mounting the displacement sensor 52 and the guide sleeve 32. A matching hole adapted to the detection head of the force sensor 51 may be provided at the right end of the connecting rod 312, and the operator may manually insert the detection head into the matching hole and manually apply pressure to perform test measurement.
[0037] It should be noted that the number of the elongated through slots 1331 provided on each of the connecting plates 133 is not limited. In the present embodiment, two elongated through slots 1331 are provided on each of the connecting plates 133 , so that the fixing frame 13 can be installed more stably.
[0038] Further, in this embodiment, referring to Figure 7, the adapter 132 includes an adapter rod 1322 extending in the left-right direction and two clamping blocks 1323 connected to the left end of the adapter rod 1322 and distributed in the up-down direction. Two connecting holes 13231 distributed oppositely in the up-down direction penetrate through the ends of the two clamping blocks 1323 facing away from the adapter rod 1322; each of the card slots 1321 is formed between the two clamping blocks 1323. By passing bolts through the two connecting holes 13231 of each adapter 132 and connecting them to the mating nuts, the position of the nuts connected to the screw rods of the bolts can be adjusted to adjust the slot width of the card slots 1321, so that the two clamping blocks 1323 clamp the corresponding guide sleeve 32 or displacement sensor 52, enabling the force sensor 51 to slide within the corresponding card slots 1321.
[0039] Furthermore, in this embodiment, two mounting surfaces are formed at the left end of each adapter rod. The two mounting surfaces are distributed oppositely in the up-down direction. At the positions corresponding to the mounting surfaces at the left end of each adapter rod, there are also a guide hole 13222 and a rotating hole 13221 penetrating in the up-down direction, and the guide hole 13222 and the rotating hole 13221 are distributed oppositely in the left-right direction. The guide hole 13222 is arc-shaped. Two adjusting holes 13232 penetrating in the up-down direction are provided at the right end of each clamping block. The two adjusting holes 13232 are spaced apart in the left-right direction and are respectively correspondingly arranged with the guide hole 13222 and the rotating hole 13221.
[0040] Among them, the adapter further includes two bolts, and the two bolts are fixedly connected in the two adjusting holes 13232. The rotating hole 13221 is provided as a threaded hole. Thus, one bolt is screwed into the rotating hole 13221, enabling the clamping block to be rotatably connected to the adapter rod so that its left end can swing back and forth, and the other bolt moves within the guide hole 13222 to limit the movement stroke of the clamping block. In this way, when hanging the simulated glass part 4, it can be tilted forward or backward to accurately simulate the actual vehicle installation state.
[0041] It should be noted that during the rotation of the clamping block, one of the bolts is always screwed into the rotating hole 13221 and will not become loose.
[0042] It should be noted that there is no limitation on the structure of connecting the two clamping blocks 1323 to the left end of the adapter rod 1322. It can be that both of the two clamping blocks 1323 are hinged to the left end of the adapter rod 1322. It can also be that in this embodiment, they are installed at the left end of the adapter rod 1322 through bolts, and there is a gap between the left ends of the two clamping blocks 1323 of each adapter 132 to facilitate adjusting the slot width of each card slot 1321.
