[0032] Before describing the embodiments according to the present invention in detail, it should be noted that, in the following, the terms “comprising,” “including,” or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0033] Please see Figures 1 to 4 As shown, the cover plate fixing structure for the drive motor of the window tilting mechanism of this utility model includes:

[0034] The cover plate body 1 is composed of soft rubber 1-1 and hard rubber 1-2. The cover plate body 1 is inserted into the fixing groove 2 of the gearbox, and the interference connection between the cover plate body 1 and the fixing groove 2 is achieved by squeezing the soft rubber 1-1 and the hard rubber 1-2.

[0035] In a preferred embodiment of this utility model, the soft adhesive 1-1 is disposed on the inner and outer rings of the cover plate body 1.

[0036] Please see Figures 5 to 6 As shown, in a preferred embodiment of the present invention, the soft rubber 1-1 has a beveled protrusion 1-3 on the outer ring of the cover plate body 1, and the beveled protrusion 1-3 forms a surface seal with the outer surface of the fixing groove 2.

[0037] In a preferred embodiment of the present invention, the soft rubber 1-1 has a round rib protrusion 1-4 on the outer ring of the cover plate body 1, and the round rib protrusion 1-4 forms a line seal with the outer surface of the fixing groove 2.

[0038] In practical applications, the cover plate body 1 is inserted into the fixing groove 2 of the gear box with an interference fit, so that the inclined protrusion 1-3 forms a surface seal with the outer surface of the groove, thereby increasing the bonding force while providing assembly guidance; the round rib protrusion 1-4 forms a line seal with the outer surface of the groove, which can effectively increase the dustproof and waterproof performance. The sealing surface mentioned here is formed by the extrusion contact between the inclined protrusion 1-3 and the outer surface of the groove, so that the surface of the inclined protrusion 1-3 and the outer surface of the fixing groove 2 are tightly fitted, forming a surface-to-surface seal; the line seal is formed by the extrusion contact between the round rib protrusion 1-4 and the outer surface of the groove, so that the feature of the round rib protrusion 1-4 and the outer surface of the fixing groove 2 form a line-surface seal.

[0039] In a preferred embodiment of the present invention, the surface of the hard rubber 1-2 is provided with a flow channel, and the soft rubber 1-1, the inclined protrusion 1-3 and the round rib protrusion 1-4 are connected through the flow channel.

[0041] In a preferred embodiment of the present invention, the cover plate body 1 is integrally formed by injection molding.

[0042] In practical applications, the cover plate fixing structure for the drive motor of the window tilting mechanism described in this technical solution is applied. By pressurizing the soft rubber 1-1 on the outer ring of the cover plate body 1 and squeezing the hard rubber 1-2 part, the inner surface of the cover plate body 1 and the fixing groove 2 of the gear box are pressed against each other, thereby further improving the cover plate holding force.
