[0031] like Figure 1 As shown, the test assembly 2 and the mounting assembly are both arranged on the frame 1, and there is a certain distance between the test assembly 2 and the mounting assembly. Due to the existence of the distance, after the glass lifter assembly 6 is installed on the mounting assembly, the test assembly 2 still retains an adjustable margin. Specifically, the thickness and tilt angle of the vehicle window of different glass lifter assemblies 6 may be different, resulting in different spaces occupied by the vehicle window in the first direction. The distance between the test assembly 2 and the mounting assembly can ensure that after the glass lifter assembly 6 is installed on the mounting assembly, there is still a gap between the glass lifter assembly 6 and the test assembly 2, and the test assembly 2 will not interfere with the glass lifter assembly 6.
[0032] The test assembly 2 includes a first mounting plate 21, a locking structure 22, an adjusting plate 23 and a speed measuring structure 24, wherein the speed measuring structure 24 is arranged at one end of the adjusting plate 23, the first mounting plate 21 is connected to the frame 1, the locking structure 22 is fixed on the first mounting plate 21, and the adjusting plate 23 can move along the first direction or the second direction relative to the locking structure 22 so that the speed measuring structure 24 contacts the glass lifter assembly 6 installed on the mounting assembly, wherein the first direction is a direction perpendicular to the plane of the glass lifter assembly 6, and the second direction is a vertical direction.
[0033] Please refer to Figure 1 and Figure 2 The test assembly 2 includes a first mounting plate 21, a locking structure 22, an adjusting plate 23 and a speed measuring structure 24.

The speed measuring structure 24 is arranged at one end of the adjusting plate 23 facing the mounting assembly. It can be understood that since the adjusting plate 23 can move relative to the locking structure 22 in a first direction, the distance between the speed measuring structure 24 and the mounting assembly is adjustable. Furthermore, when testing different glass lifter assemblies 6, by changing the position of the adjusting plate 23 in the first direction, the speed measuring structure 24 can be in contact with the windows of different glass lifter assemblies 6, so as to test the lifting speeds of different glass lifter assemblies 6, thereby expanding the scope of application of the test bench of the glass lifter assembly of the embodiment of the present application. In addition, since the windows of different glass lifter assemblies 6 may have tilt angles, the speed measuring structure 24 needs to contact different areas on the window to accurately test the lifting speed of the glass lifter. In the test assembly 2 of the embodiment of the present application, the adjustment plate 23 can move along the second direction on the basis of being able to move relative to the locking structure 22 along the first direction, so that it can contact different areas on the window and accurately test the lifting speed of different glass lifters. The first direction is Figure 1 The front-to-back direction shown, the second direction Figure 1 Up and down directions shown.
[0034] Optionally, the locking structure 22 includes a bottom plate 221 and two locking plates 222, the bottom plate 221 is fixed on the first mounting plate 21, the two locking plates 222 are arranged on the bottom plate 221 opposite to each other, and there is an adjustment space between the two locking plates 222 for the adjustment plate 23 to slide. The two locking plates 222 are provided with a plurality of pairs of locking holes 223 correspondingly arranged along the second direction, and the adjustment plate 23 is provided with a locking groove 231 arranged along the first direction. When the adjustment plate 23 is slid to a target position in the adjustment space, the adjustment plate 23 can be fixed by fasteners passing through the pair of locking holes 223 and the locking groove 231 corresponding to the target position.

Two locking plates 222 are disposed on the bottom plate 221, and the bottom ends of the locking plates 222 are fixed on the bottom plate 221. An adjustment space is formed between the two locking plates 222, and the adjustment plate 23 is disposed in the adjustment space. The adjustment plate 23 slides with the locking plates 222 on both sides. Figure 2 In the illustrated embodiment, four locking holes 223 are provided on the locking plate 222, and the four locking holes 223 are arranged at intervals in the vertical direction, and each locking hole 223 has another corresponding locking hole 223 at a corresponding position on another locking plate 222. A locking groove 231 is provided on the adjustment plate 23, and after the glass lifter assembly 6 is installed on the mounting assembly, the adjustment plate 23 is moved along the first direction and the second direction to the target position, so that the speed measuring structure 24 at the end of the adjustment plate 23 contacts the glass lifter assembly 6, and then a fastener is used to pass through the locking hole 223 and the locking groove 231 corresponding to the target position, and the adjustment plate 23 is fixed. In this embodiment, the adjusting plate 23 and the locking plate 222 are slidably matched, and combined with the locking groove 231 set along the first direction on the adjusting plate 23 and the multiple locking holes 223 set along the second direction on the locking plate 222, when facing different glass lifter assemblies 6, the adjusting plate 23 can be adjusted to the corresponding position to meet the testing requirements. The locking structure 22 has a simple and compact structure and is easy to operate.

It should be noted that due to the different designs of the glass lifter assembly 6, the distances between the windows of the glass lifter assembly 6 at different positions in the third direction and the speed measuring structure 24 may also be different. In order to accurately test the lifting speed of the glass lifter, it is necessary to select multiple areas of the windows in the third direction for testing. The setting of the first mounting plate 21 in the embodiment of the present application can meet this requirement, further expanding the scope of application of the test bench of the glass lifter assembly in the embodiment of the present application. Among them, the third direction is Figure 1 Left and right directions shown.

The roller 242 is arranged in the rolling groove 244, and the rolling connection relationship between the roller 242 and the mounting seat 241 can be achieved by the cooperation between the shaft and the hole. By adjusting the position of the first mounting plate 21 and the adjusting plate 23, after the roller 242 contacts the vehicle window, when the vehicle window is raised or lowered, the roller 242 will roll under the friction between the roller 242 and the vehicle window, and the rolling speed of the roller 242 is proportional to the lifting speed of the vehicle. The sensor can detect the motion parameters of the roller 242, thereby detecting the lifting speed of the glass lifter. In this embodiment, the speed measuring structure 24 has a simple structure and is easy to install and use.
