[0023] The following is a clear and complete description of the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] Example 1

[0025] refer to Figures 1 to 4 A protective structure for a steering bearing 5 of an electric vehicle includes a steering column 1 and a lower connecting plate 2 connected to the lower end of the steering column 1; the steering column 1 is provided with a steering bearing 5, and further includes a protective plate 3 arranged between the lower connecting plate 2 and the steering bearing 5, and the protective plate 3 is provided with a through hole 31 for the steering column 1 to pass through; the protective plate 3 is installed on the electric vehicle housing 4 and is used to close the open mounting port 41 of the electric vehicle housing 4.

[0026] When the existing electric vehicle is running, the sealing performance of the steering column 1 is poor, and rainwater, mud and stones and other fine debris can easily enter therein, which has a low protection effect on the steering bearing 5.

[0027] In this embodiment, a protective plate 3 is provided between the lower connecting plate 2 and the steering bearing 5. At the same time, the protective plate 3 can close the open installation opening 41 of the electric vehicle housing 4, thereby achieving a sealing effect, making it difficult for rainwater, mud and stones and other fine debris to enter, and preventing mud and stones from entering the steering bearing 5 at the source, thereby solving the steering jam caused by mud and sand entering the steering bearing 5, and thus improving the driving safety factor.

[0028] Specifically, the protective plate 3 is arranged on the upper end surface of the lower connecting plate 2. As a preferred embodiment of the present invention, the protective plate 3 is made of stainless steel. Made of stainless steel, it can extend the service life.

[0029] In other embodiments, the protective plate 3 and the lower connecting plate 2 are integrally formed. The advantages are: the protective plate 3 and the lower connecting plate 2 are integrally formed without the need for an additional mold to produce the protective plate 3, which not only saves production costs, but also reduces assembly difficulty and improves the sealing effect.

[0030] In this embodiment, screw holes 32 are provided on the protective plate 3, specifically, screw holes 32 are provided at the four corners of the protective plate 3; the protective plate 3 is detachably connected to the electric vehicle housing 4 through the screw holes 32. It should be noted that the protective plate 3 is installed inside the electric vehicle housing 4, and the electric vehicle housing 4 is provided with holes corresponding to the screw holes 32, so that the protective plate 3 is located inside the electric vehicle housing 4 and closes the open installation opening 41 of the electric vehicle housing 4. Of course, in actual application, a position for the power supply line to pass through needs to be reserved at the electric vehicle housing 4. Preferably, the position where the power supply line passes through is away from the steering column 1, so as to avoid the steering bearing 5 being affected. For reference, Figure 1 .

[0031] In this embodiment, the upper end surface of the lower connecting plate 2 is provided with a guide post 21, and the protective plate 3 is provided with a positioning hole 33 corresponding to the guide post 21. During assembly, the guide post 21 serves as a positioning and calibration for the installation of the remaining frame components, and during driving, the guide post 21 serves as a steering limiter.

[0032] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and intent of the present application, and that the scope of the present application is defined by the claims and their equivalents.
