[0056] Example 1:

[0057] In existing technology, vehicle switches are devices that control the on / off or adjustment status of various electrical devices in a car. Vehicle switches commonly use rotary drives for this purpose, such as window switches. Before mass production and installation, existing vehicle switches require durability testing. This durability test involves simulating use by repeatedly switching the switch on and off under specific testing conditions to verify its ability to maintain normal function over long-term use. However, existing vehicle switch durability testing machines cannot be adjusted to accommodate these limitations, limiting their testing to a single model of switch. This results in a narrow range of applications and low testing efficiency.

[0058] Please refer to the attached document. Figure 1 To be continued Figure 5 As shown, the first direction X of this application refers to the width direction of the switch durability testing device 20, that is, the direction from front to back or from back to front. In this application, both the first rotation axis 11 and the second rotation axis 400 are arranged along the first direction X. The second direction Y of this application refers to the height direction of the switch durability testing device 20, that is, the direction from top to bottom or from bottom to top. In this application, the first connecting plate 510 is arranged higher than the second connecting plate 520, and the second connecting plate 520 is arranged lower than the first connecting plate 510. The third direction Z of this application refers to the length direction of the switch durability testing device 20, that is, the direction from left to right or from right to left. The second direction Y of this application refers to the setting direction of the first mounting plate 110.

[0059] The switch durability testing device 20 of this application needs to test the service life of the switch 10 under special conditions.

Furthermore, the switch 10 of this application has a first rotation axis 11 arranged along a first direction X. The switch 10 rotates around the first rotation axis 11 to form corresponding control. The switch 10 also includes a touch part 12, which is the part of the switch 10 that contacts the switch durability testing device 20. During the specific testing process, the switch durability testing device 20 needs to connect the switch 10 to a testing system, which is used to determine whether the switch 10 is operating normally.

[0060] In one embodiment, switch 10 is a window lift control switch 10, and switch 10 can be a single setting or a combination of four settings.

[0061] Appendix Figure 1 This is a schematic diagram of one structure of the switch durability testing device 20 of this application. Please refer to the attached diagram. Figure 1 As shown, the switch durability testing device 20 of this application includes a test chamber. In a specific test, at least the switch 10 is located inside the test chamber, or even all other structures in the switch durability testing device 20 except for the test chamber are housed inside the test chamber. The test environment is arranged inside the test chamber.

[0062] In one embodiment, the test environment is a high-temperature environment, a low-temperature environment, or a high-humidity environment.

[0063] Please refer to the attached document. Figure 1 As shown, the switch durability testing device 20 of this application also includes a frame 500, which is arranged along the second direction Y. The mounting component 100, transmission component 200 and drive component 300 of this application are all mounted on the frame 500. The positional relationship between the mounting component 100, transmission component 200 and drive component 300 and the frame 500 will be further explained in the following figures.

[0064] In one embodiment, the frame 500 includes a first connecting plate 510 and a second connecting plate 520 spaced apart along a first direction X. The frame 500 also includes a first connecting rod 540, which is positioned between the first connecting plate 510 and the second connecting plate 520 along the first direction X. Both ends of the first connecting rod 540 along the first direction X are connected to the first connecting plate 510 and the second connecting plate 520, respectively. The frame 500 also includes a third connecting plate 530, which is located at the bottom of the second connecting plate 520 along the first direction X.

[0065] Please refer to the attached document. Figure 1As shown, the switch durability testing device 20 of this application includes a mounting component 100, which is disposed on the top of the frame 500 along the first direction X. The mounting component 100 is used to fix the test switch 10, and the test switch 10 is located in the test environment. The specific structure of the mounting component 100 will be further described in the following figures.

[0066] Please refer to the attached document. Figure 1 As shown, the switch durability testing device 20 of this application also includes a drive component 300 and a transmission component 200. The transmission component 200 is connected to the switch 10 in a transmission manner, and the drive component 300 is connected to the transmission component 200 to drive the transmission component 200 to rotate and drive the switch 10 to rotate around the first rotation axis 11.

[0067] The transmission assembly 200 of this application includes a first transmission plate 210, which is disposed along the second direction Y and is connected to the frame 500. Furthermore, the first transmission plate 210 is connected to the frame 500 via a movable connection, and the portion of the first transmission plate 210 connected to the frame 500 is a first connecting plate 510.

[0068] The transmission assembly 200 of this application further includes a first rotating shaft 220, which is arranged along a first direction X. A second rotating axis 400 is arranged within the first rotating shaft 220 along the first direction X. In practical use, the first rotating axis 11 coincides with the second rotating axis 400, and the first rotating shaft 220 is rotatably connected to the first transmission plate 210. Therefore, the reference for adjusting the relative position between the mounting assembly 100 and the transmission assembly 200 using the switch durability testing device 20 is the relative position between the first rotating axis 11 and the second rotating axis 400. Furthermore, when the first rotating axis 11 and the second rotating axis 400 coincide, the switch durability testing device 20 can highly simulate the real-world usage scenario of the switch 10 when performing durability testing on the switch 10, thus ensuring the accuracy of the test data.

[0069] The transmission assembly 200 of this application further includes a first clamping part 230 and a first connecting part 240. The first clamping part 230 is connected to the first rotating shaft 220 through the first connecting part 240. The first clamping part 230 is used to clamp the touch part 12 in the switch 10 so as to realize the synchronous rotation of the switch 10 and the transmission assembly 200.

[0070] The transmission assembly 200 of this application further includes a first intermediate block 250. A first transmission plate 210 is connected to a first connecting plate 510 through the first intermediate block 250, and the first transmission plate 210 is movably connected to the first connecting plate 510 through the first intermediate block 250.

Part of the first transmission plate 210 is located above the first connecting plate 510, and the other part of the first transmission plate 210 is located between the first connecting plate 510 and the second connecting plate 520.

[0071] Furthermore, the first transmission plate 210 has a second sliding groove 260 along the second direction Y. The first transmission plate 210 is movably connected to the first connecting plate 510 along the second direction Y through the second sliding groove 260, thereby realizing the position adjustment of the first rotating shaft 220 on the first connecting plate 510 relative to the switch 10 along the second direction Y. The first intermediate block 250 is provided with a third sliding groove 270 along the third direction Z. The first intermediate block 250 is movably connected to the first connecting plate 510 along the third direction Z through the third sliding groove 270, thereby realizing the adjustment of the first rotating shaft 220 on the first connecting plate 510 relative to the switch 10 along the third direction Z, thus realizing the applicability of the switch durability testing device 20 to switches 10 of different specifications. In this application, switches 10 of different specifications refer to switches of different sizes or switches with different positions of the first rotating axis 11.

[0072] Appendix Figure 2 This is a schematic diagram of a structure between the mounting component 100 and the switch 10 in this application. Please refer to the attached diagram. Figure 2 As shown, the mounting assembly 100 of this application includes a first mounting plate 110 and a second mounting plate 120. The first mounting plate 110 is disposed along a third direction Z, and a fourth sliding groove is provided on the first mounting plate 110 along the third direction Z. Two second mounting plates 120 are disposed at intervals along the third direction Z on the first mounting plate 110 to form a first clamping space 130 that can be located between the two second mounting plates 120. The first clamping space 130 is used to accommodate the switch 10. The second mounting plates 120 are movably connected to the first mounting plate 110 along the third direction Z, thereby realizing the adjustable position of the first clamping space 130 in the third direction Z, so as to further realize the adjustment of the switch 10 relative to the first rotation axis 220 in the third direction Z.

[0073] Please refer to the attached document. Figure 2As shown, the mounting assembly 100 of this application also includes a first driving member 140. The first mounting plate 110 and the frame 500 are spaced apart along the second direction Y, that is, the first mounting plate 110 and the first connecting plate 510 are spaced apart along the second direction Y. The first driving member 140 is located between the first mounting plate 110 and the frame 500. The two ends of the first driving member 140 along the second direction Y are respectively connected to the first mounting plate 110 and the frame 500. Under the drive of the first driving member 140, the first mounting plate 110 moves closer to or further away from the frame 500 to adjust the relative position of the switch 10 and the transmission assembly 200 in the second direction Y within the first clamping space 130.

[0074] Appendix Figure 3 This is a schematic diagram of a structure between the transmission assembly 200 and the drive assembly 300 of this application. Please refer to the attached diagram. Figure 3 As shown, the transmission assembly 200 of this application includes a first transmission plate 210. The first transmission plate 210 is used to support other components in the transmission assembly 200 besides itself, and further supports part of the drive assembly 300. The first transmission plate 210 is arranged along the second direction Y and is connected to the frame 500. Furthermore, the first transmission plate 210 is connected to the first connecting plate 510 through a first intermediate block 250.

[0075] Please refer to the attached document. Figure 3 As shown, the transmission assembly 200 of this application further includes a first rotating shaft 220, which is arranged along a first direction X. A second rotating axis 400 is arranged inside the first rotating shaft 220 along the first direction X. To accommodate the testing of switches 10 of different specifications, after adjusting the relative position between the first rotating shaft 220 and the switch 10, the first rotating shaft 220 coincides with the first rotating axis 11. Furthermore, the first rotating axis 11 coincides with the second rotating axis 400. Under the drive of the drive assembly 300, the first rotating shaft 220 rotates around the second rotating axis 400, and the first rotating shaft 220 is rotatably connected to the first transmission plate 210.

[0076] Please refer to the attached document. Figure 3 As shown, the transmission assembly 200 of this application further includes a first clamping part 230 and a first connecting part 240. The first clamping part 230 is connected to the first rotating shaft 220 through the first connecting part 240. The first clamping part 230 is used to clamp the switch 10. The first rotating shaft 220 drives the first clamping part 230 to rotate through the first connecting part 240, thereby causing the switch 10 located in the first clamping part 230 to rotate.

[0077] Please refer to the attached document. Figure 3As shown, the drive assembly 300 of this application includes a first drive wheel 310 and a second drive wheel 320. The drive assembly 300 transmits power through the rotation of the first drive wheel 310 and the second drive wheel 320. The first drive wheel 310 and the second drive wheel 320 are spaced apart along a second direction Y. The first drive wheel 310 is connected to a first rotating shaft, and the rotational power of the first rotating shaft is provided by the first drive wheel 310. The first drive wheel 310 and the second drive wheel 320 are mounted on a first transmission plate 210 and are rotatably connected to the first transmission plate 210. Both the first drive wheel 310 and the second drive wheel 320 are provided with transmission grooves for mounting a transmission belt to achieve rotation of the first drive wheel 310 and the second drive wheel 320.

[0078] Please refer to the attached document. Figure 3 As shown, the drive assembly 300 of this application includes a first transmission sleeve 330, which is a ring-shaped structure formed by a transmission belt. The first transmission sleeve 330 is sleeved on the outside of the first drive wheel 310 and the second drive wheel 320, and the second drive wheel 320 transmits power to the first drive wheel 310 through the first transmission sleeve 330.

[0079] Please refer to the attached document. Figure 3 As shown, the drive assembly 300 of this application includes a first drive belt 340, a first counterweight 350, and a second counterweight 360. The first drive belt 340 is open and has a first end and a second end in its length direction. The first drive belt 340 is sleeved on the second drive wheel 320. The two ends of the first drive belt 340 are respectively connected to the first counterweight 350 and the second counterweight 360. The rotation of the second drive wheel 320 is achieved by adjusting the height difference between the first counterweight 350 and the second counterweight 360 in the second direction Y. The first drive wheel 310 is driven to rotate through the first drive sleeve 330.

[0080] Please refer to the attached document. Figure 3 As shown, the drive assembly 300 of this application also includes a second drive member 370, which is connected to the first counterweight 350. The second drive member 370 is used to drive the first counterweight 350 to move along the second direction Y to form a height difference between the first counterweight 350 and the second counterweight 360 in the second direction Y, and to form the second drive wheel 320 to rotate.

[0081] The second driving component 370 includes a first driving plate 371, which is located at the bottom of the first counterweight 350 along the second direction Y. The first driving plate 371 abuts against the first counterweight 350 to support it. The second driving component 370 also includes a first driving structure 372, located at the bottom of the first driving plate 371 along the second direction Y, which drives the first driving plate 371 to move along the second direction Y. The second driving component 370 also includes a first guide structure 373, which is disposed along the second direction Y, and the first driving plate 371 is slidably connected to the first guide structure 373.

[0082] The specific number of drive components 300 and transmission components 200 depends on the number of switches 10. The switch durability testing device 20 of this application can test one or more switches 10. In one embodiment, the switch durability testing device 20 is used to test the window lift switch 10, so the number of switches 10 is one or four. When the switch durability testing device 20 tests only one switch 10, only one set of drive components 300 and transmission components 200 is needed. When the switch durability testing device 20 tests four switches 10, multiple sets of drive components 300 and transmission components 200 are required. To reduce the overall cost of the switch durability testing device 20, the first drive plate 371 of this application simultaneously supports two first counterweights 350.

[0083] In one embodiment, the first guide structure 373 includes a first guide plate and a first guide post. The first guide plate and the first guide post are both arranged along the first direction X. The first guide plate and the first guide post are spaced apart. The first guide plate is connected to the first connecting plate 510. The first guide post and the first guide plate are connected by a limiting block. The first drive plate 371 is slidably connected to the first guide plate.

[0084] In practical use, when the first drive plate 371 moves upward along the second direction Y, the first counterweight 350 moves upward simultaneously under the drive of the first drive plate 371. At this time, the second counterweight 360 moves downward under the influence of its own gravity, thus causing the second drive wheel 320 to rotate in the opposite direction. When the first drive plate 371 moves downward along the second direction Y, the first counterweight 350 moves downward under the influence of its own gravity. The first drive plate 371 provides support to the first counterweight 350 in the second direction Y. At this time, the second counterweight 360 moves upward, thus causing the second drive wheel 320 to rotate in the forward direction.

[0088] Please refer to the attached document. Figure 4 and appendix Figure 5 As shown, the drive assembly 300 of this application further includes a first clamping portion 230 and a first connecting portion 240.
