[0034] In view of the above situation, the present application provides a vehicle door glass lifter durability test device, which can simultaneously perform durability tests on multiple door glass lifters, shortening the test time and improving the test efficiency. Figure 1-Figure 3 , a detailed introduction is given to the basic structure, working principle and technical effects achieved by a vehicle door glass lifter durability test device provided in this application.

[0035] First embodiment

[0036] Please refer to Figure 1 , this embodiment provides a vehicle door glass lifter durability test device, which includes a test bench 200 and a test control component 300. The test bench 200 is a rectangular frame structure. In order to reduce the overall weight of the test bench 200, the test bench 200 in this embodiment is assembled from aluminum alloy profiles. The test bench 200 is used to provide an installation space for the vehicle door 100. The test control component 300 is installed on the test bench 200. The test control component 300 is connected to the glass lifter in the vehicle door 100 to be tested. The test control component 300 is used to control the opening and closing of the glass lifter to be tested. At least one fixing component 400 is provided on the test bench 200, and the fixing component 400 is used to fix the vehicle door 100 to be tested. As Figure 1As shown, in this embodiment, four fixing assemblies 400 are provided on the test bench 200, which can simultaneously fix four vehicle doors 100 to be tested. In other embodiments, the number of fixing assemblies 400 can also be set to other numbers according to test requirements.

[0037] During a durability test of a glass lifter, the door frame seal, glass run channel, lift glass, and lifter assembly are installed on the vehicle door 100 assembly according to design requirements. The assembled vehicle door 100 is then mounted on a test bench 200 and secured using a fixing assembly 400. The lifter assembly is then connected to a test control assembly 300, which controls the lift glass to repeatedly lift and lower the lift glass for the durability test. Because the test bench 200 in this embodiment is equipped with at least one fixing assembly 400, the number of fixing assemblies 400 can be adjusted based on actual usage requirements, allowing for simultaneous testing of multiple vehicle doors 100. This significantly improves testing efficiency compared to current techniques for testing a single vehicle door 100.

[0038] Please refer to Figure 1 The fixings include a pad 410, a support rod 420, and a connector 430. The pad 410 is a rectangular rubber block fixedly connected to the lower frame of the test bench 200. A V-shaped snap-in slot 411 is provided on the pad 410. The snap-in slot 411 is used to accommodate and snap onto the bottom of the vehicle door 100. The support rod 420 is vertically arranged between the upper and lower frames of the test bench 200 and is located on one side of the pad 410. The support rod 420 is used to provide support for the vehicle door 100. The connector 430 is arranged on the upper portion of the support rod 420. The connector 430 is connected to the upper portion of the vehicle door 100 and is used to fix the upper portion of the vehicle door 100.

[0039] When the vehicle door 100 to be tested is mounted on the test bench 200, the lower end of the vehicle door 100 is snapped onto the pad 410, the vehicle door 100 is slightly tilted and leaned against the support rod 420, and the upper end of the vehicle door 100 is connected to the support rod 420 via the connector 430. This secures the vehicle door 100 at three points: the top, middle, and bottom. This ensures that the vehicle door 100 is securely mounted on the test bench 200. Furthermore, the installation method of the vehicle door 100 in this embodiment is simple and easy to operate, facilitating installation and removal of the vehicle door 100 from the test bench 200 and further improving testing efficiency.

[0040] Please refer to Figure 1 In this embodiment, the connecting member 430 includes a cable tie or a binding rope, and the upper part of the vehicle door 100 can be connected to the support rod 420 by the cable tie or the binding rope. It is easy to operate, low in cost, and has a wide range of applications.

[0041] Please refer to Figure 1The test control assembly 300 includes a first limit switch 310, a second limit switch 320, and a test controller 330. The first limit switch 310 is mounted on the vehicle door 100 by bonding or threading, and is located at the bottom of the vehicle window frame. The second limit switch 320 is also mounted on the vehicle door 100 by bonding or screwing, and is located at the top of the vehicle window frame. Aluminum foil is applied to the lift window at locations corresponding to the first and second limit switches 310, 320. The first and second limit switches 310, 320 are both electrically connected to the test controller 330, which is in turn electrically connected to the window lifter.

[0042] The controller activates the window lifter in vehicle door 100. When the lifter reaches its highest position, the aluminum foil on the lifter aligns with the second limit switch 320. Based on the aluminum foil's conductivity, reflectivity, or its ability to block or reflect light, the second limit switch 320 triggers a sensing element within the second limit switch 320, closing the second limit switch 320. This activates the window lifter via the test controller 330, driving the lifter downward. When the lifter reaches its lowest position, the aluminum foil on the lifter aligns with the first limit switch 310, closing the first limit switch 310 and activating the window lifter via the test controller 330, driving the lifter upward.

[0043] According to vehicle design requirements, the design rise time of the glass lift is less than or equal to 3.8 seconds, and the design fall time of the glass lift is less than or equal to 3.5 seconds. Furthermore, the glass lift is stalled for 0.5 seconds at both its upper and lower dead stops. Test controller 330 is also used to monitor the rise and fall times of the glass lift. After frequent lifting and lowering of the glass lift, the change in the rise and fall times relative to the design times can be used to determine whether the glass lift meets the durability test requirements.

[0044] To further improve the accuracy of the window lifter durability test, an ammeter and voltmeter are electrically connected to the window lifter. This meter detects the operating voltage and current of the window lifter motor, thereby determining the stability of the window lifter during long-term use. The ammeter and voltmeter are also integrated into the controller, allowing real-time monitoring of the window lifter motor's operating voltage and current through the controller panel.

[0045] During the durability test of the glass lifter, it is usually necessary to conduct the durability test of the glass lifter in a high or low temperature environment to simulate the use of the vehicle in extreme environments. Figure 1The test bench 200 is equipped with multiple universal wheels 210 at its base, making it easy to move. To conduct tests in high or low temperature environments, the test controller 330 is removed from the test bench 200, the associated wiring harness is appropriately extended, and the test bench 200 is pushed into the high or low temperature chamber using the universal wheels 210. This further expands the applicability of the test device.

[0046] The working principle of the vehicle door glass lifter durability test device is as follows: according to the test requirements, multiple fixing components 400 can be set on the test bench 200, so that multiple vehicle doors 100 can be installed on the test bench 200, making it convenient to perform durability tests on the glass lifters on multiple vehicle doors 100 at the same time, thereby improving test efficiency.

[0047] Second embodiment

[0048] The vehicle door glass lifter durability testing device provided in this embodiment includes a test bench 200 , a test controller 330 , and a fixing assembly 400 .

[0049] In this embodiment, lugs are connected to both sides of the support rod 420, and fixing bolts 440 are inserted through the lugs. Fixing bolts 440 are also inserted through the pad 410. Thus, the support rod 420 and the pad are detachably connected to the frame of the test bench 200 via the fixing bolts 440. This facilitates adding or reducing the number of support rods 420 and pads 410 on the test bench 200, thereby adjusting the number of vehicle doors 100 that can be installed on the test bench 200 according to test requirements, further expanding the applicability of the test apparatus.

[0050] Third embodiment

[0051] The vehicle door glass lifter durability testing device provided in this embodiment includes a test bench 200 , a test controller 330 , and a fixing assembly 400 .

[0052] In this embodiment, a slide groove 220 is provided on both the upper and lower frames of the test bench 200. The cross-section of the slide groove 220 is T-shaped or dovetail-shaped. A plurality of sliders 230 are slidably disposed on the test bench 200 and within the slide groove 220. The plurality of sliders 230 correspond one-to-one with the plurality of fixing assemblies 400. Pads 410 and support rods 420 are detachably disposed on the sliders 230. A locking bolt 240 is threaded through the sliders 230. By loosening or tightening the locking bolt 240, the slider 230 can be secured to different positions on the test bench 200. By adjusting the position of the slider 230 on the test bench 200, the position of the test vehicle door 100 on the test bench 200 can be adjusted to meet different test requirements, further enhancing the applicability of the test device.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
