[0006] Preferably, the fixing mechanism comprises a U-shaped fixing frame, a hexagonal bolt, a rotation handle and a pressing plate, the U-shaped fixing frame is fixed on the bracket through the hexagonal bolt on both sides, and one end of the rotation handle is inserted into the middle part of the U-shaped fixing frame and is fixedly connected to the pressing plate.

[0007] Preferably, the rotation handle is threadedly connected to the U-shaped fixing frame.

[0008] Preferably, the pressing plate is provided with a limiting block on both sides, the U-shaped fixing frame is provided with a sliding groove, and the limiting block moves up and down along the sliding groove.

[0009] Preferably, rubber is pasted in the semicircular recess, and rubber is pasted on the inner side of the round hoop.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] Simple structure, convenient operation: the scheme is carefully designed for the fixing structure of the wiper motor, aiming to make the installation and disassembly process more convenient and efficient. By adopting the combination of the round hoop, bracket and fixing mechanism, the motor is directly and stably installed on the cross beam, greatly simplifying the installation steps and reducing the implementation difficulty. In addition, this design also achieves the goal of quick fixing, ensuring that the entire installation process is both fast and reliable.

[0012] Enhanced rigidity, extended life: under the premise of meeting the actual operation demand, the improvement significantly improves the rigidity and stability of the wiper motor system, thereby effectively extending its service life and reducing maintenance cost and potential failure risk.
