[0047] The horizontal installation plate 201 is welded between the lower half sections of the two vertical support rods, and the driving wheel 5 is rotatably installed on the horizontal installation plate 201. The horizontal U-shaped installation frame 502 is welded to the end of the rotating shaft of the driving wheel 5 away from the driving wheel 5. The horizontally arranged U-shaped driving frame 503 is slidably installed on the U-shaped installation frame 502. The two driving wedges 9 are symmetrically welded to the first ends of the two longitudinally arranged side rods of the U-shaped driving frame 503. The two six-ribbed slide rods 504 are symmetrically and slidably installed at the first ends of the two longitudinally arranged side rods of the U-shaped installation frame 502. The two V-shaped clamping plates 5041 are symmetrically welded to the opposite ends of the two six-ribbed slide rods 504. When the two V-shaped clamping plates 5041 are slid towards each other, they are in contact with the top of the rotating shaft of the windshield wiper driving motor 7, and are used to connect the rotating shaft of the windshield wiper driving motor 7 with the driving wheel 5. The two force wedges 8 are symmetrically welded to the ends of the two six-ribbed slide rods 504 away from each other. When the U-shaped driving frame 503 slides towards the six-ribbed slide rods 504, the inclined surfaces of the driving wedges 9 on the U-shaped driving frame 503 are in contact with the inclined surfaces of the force wedges 8 on the six-ribbed slide rods 504.

The rotating shaft of the windshield wiper driving motor 7 can be indirectly connected with the U-shaped installation frame 502 through the power transmission of the U-shaped driving frame 503. Based on the above power transmission through the U-shaped installation frame 502, the rotating shaft of the windshield wiper driving motor 7 is finally indirectly connected with the driving wheel 5.

[0049] Through the inclined surface guiding principle generated by the contact between the driving wedges 9 on the U-shaped driving frame 503 and the force wedges 8 on the six-ribbed slide rods 504, when the U-shaped driving frame 503 slides towards the six-ribbed slide rods 504, the two six-ribbed slide rods 504 and the two V-shaped clamping plates 5041 can be simultaneously driven to slide towards each other and be in contact with the top of the rotating shaft of the windshield wiper driving motor 7, so as to drive connect the windshield wiper driving motor 7 and the driving wheel 5. When the U-shaped driving frame 503 slides away from the six-ribbed slide rods 504, the driving wedges 9 on the U-shaped driving frame 503 are separated from the force wedges 8 on the six-ribbed slide rods 504, so that the two V-shaped clamping plates 5041 lose the pushing and holding force from the U-shaped driving frame 503 and release the rotating shaft of the windshield wiper driving motor 7, and the power connection between the rotating shaft and the driving wheel 5 is disconnected. When the windshield wiper driving motor 7 is disassembled and replaced, the two V-shaped clamping plates 5041 need to be released to release the rotating shaft of the windshield wiper driving motor 7.

[0050] Preferably, the U-shaped installation frame 502 is welded to the bottom of the end of the horizontal installation plate 201, and the vertical hanging rod 5021 is welded to the bottom of the end of the U-shaped installation frame 502.

[0053] Through the inclined surface guiding principle generated by the contact between the drive wedge 9 on the U-shaped sliding frame 205 and the force wedge 8 on the six-pronged slide rod 204, when the U-shaped sliding frame 205 slides towards the six-pronged slide rod 204, the two six-pronged slide rods 204 and the two V-shaped clamping plates 2041 can be synchronously driven to slide towards each other and contact the windshield wiper drive motor 7, thereby clamping and fixing the windshield wiper drive motor 7; when the U-shaped sliding frame 205 slides away from the six-pronged slide rod 204, the drive wedge 9 on the U-shaped sliding frame 205 is separated from the force wedge 8 on the six-pronged slide rod 204, the two V-shaped clamping plates 2041 lose the pushing and holding force from the U-shaped sliding frame 205 and can release the windshield wiper drive motor 7, thereby disassembling and replacing the windshield wiper drive motor 7;

[0054] The two V-shaped clamping plates 2041 can clamp and fix windshield wiper drive motors 7 of different sizes within a certain range, and the combined use of the two V-shaped clamping plates 2041 can improve the versatility of the test platform to a certain extent.

In this working condition, the forward or backward rotation of the six-ribbed transmission shaft 207 can drive the threaded shaft 505 and the threaded sleeve 206 to rotate forward or backward synchronously, so as to tighten or loosen the rotating shaft of the wiper drive motor 7 and the body of the wiper drive motor 7 at one time. This can save the trouble of sequentially performing the above two operations step by step when the wiper drive motor 7 is disassembled and replaced, and is convenient for operation and use, which helps to simplify the replacement operation efficiency of the wiper drive motor 7 and indirectly improves the overall test use efficiency of the test platform.
