The windshield wiper can clean the rainwater on the front windshield, provide a clear vision for the driver, and thus reduce the occurrence of accidents. The rotation of the windshield wiper is driven by a windshield wiper motor, which is usually installed on a mounting plate under the front windshield for easy maintenance by people.
[0003] The existing patent (Publication No.: CN218071193U) discloses a small motor with a protection mechanism, which relates to the technical field of motors. It includes a motor body, a mounting plate is fixedly connected to the bottom of the motor body, a protective cover is fixedly connected to the top of the mounting plate, the motor body is located inside the protective cover, a group of first buffer mechanisms are installed at the bottom of the mounting plate, the bottoms of the group of first buffer mechanisms are commonly connected to a base, and two second buffer mechanisms are commonly installed between the base and the mounting plate, and the two second buffer mechanisms are symmetrically arranged; for the technical solution disclosed in the above patent document, through practice, it is considered that there are still the following technical problems: 1.

Content of the Utility Model
[0004] The purpose of the utility model is to provide a motor with a protection mechanism to solve the problems of the relatively large volume of this device and the difficulty in blocking sundries mentioned in the above background art.

A number of springs are distributed on the inner walls of the two semi-circular shells, and a number of springs are in contact with the outer wall at the lower end of the windshield wiper motor. Two clamping plates are connected to the same-side edges of the two semi-circular shells respectively. A fastening plate is arranged between the clamping plates of the two semi-circular shells. Two pairs of clamping bars are connected to the fastening plate. The positions of the two pairs of clamping bars correspond to the clamping plates on the two semi-circular shells. Fasteners penetrate through the two pairs of clamping bars and the four clamping plates.

[0010] As a preferred embodiment, the output shaft of the wiper motor rotates through the mudguard head, and a retaining ring is connected to the output shaft of the wiper motor. The retaining ring is located outside the mudguard head.
[0011] With the above scheme, by setting the retaining ring, the position of the mudguard head can be assisted in being restricted, and the retaining ring can block a part of the dirt from entering the mudguard head.
[0012] As a preferred embodiment, several sponge strips are connected to the inner walls of the two semi-circular shells, and sponge pads are connected to the ratios of the two semi-circular shells. The sponge strips and sponge pads are both in contact with the outer wall of the lower end of the wiper motor.

[0014] As a preferred embodiment, the four clamping plates and the two pairs of jacks are provided with jacks at corresponding positions, the fasteners are located in a plurality of jacks, and two mounting holes are provided on both sides of the fastening plate.
[0015] With the above solution, by setting the jacks, the fasteners can conveniently fix the semi-circular shell and the fastening plate together, and by setting the mounting holes, the installation of the device can be facilitated.
[0016] As a preferred embodiment, a mounting groove is provided on the middle plate of the wiper motor, and the upper ends of the two semi-circular shells are both clamped in the mounting groove, and a plurality of fixing screws are threadedly connected around the mounting groove.
