[0026] Example:

[0027] Reference Figures 1 to 4This embodiment proposes a waterproof structure for a rearview mirror motor connector, including a connector 2 and a waterproof sleeve 5 sleeved on the outside of the connector 2. A waterproof convex portion 8 and a waterproof concave portion that cooperate with each other are formed between the waterproof sleeve 5 and the connector 2. The waterproof concave portion close to the motor side and the corresponding waterproof convex portion 8 are inclined toward the side away from the motor. After the waterproof sleeve 5 is installed, the waterproof concave portion and the waterproof convex portion 8 are tightly fitted. The concave-convex fitting of the waterproof concave portion and the waterproof convex portion 8 between the mutually sleeved connector 2 and the waterproof sleeve 5 can form a well-sealed space at the interface. Even in the event of force deformation or other accidents, the concave-convex fitting can significantly increase the sealing performance of the interface. Moreover, such concave-convex fitting can also resist small gaps caused by component fatigue, aging, etc. to a certain extent, thereby extending the service life. Figure 4 As shown, since the waterproof protrusion 8 and the waterproof recess are tilted in the direction away from the motor, that is, tilted to the right, when the connector 2 and the waterproof cover 5 have a tendency to move away from each other, the tilted arrangement of the waterproof recess and the waterproof protrusion 8 has a better bite, thereby making the stability better. In addition, during installation, the waterproof cover 5 is placed as shown in FIG. Figure 4 When installing from right to left, the waterproof protrusion 8 and the waterproof recess are in a direction that is easy to deform. Obviously, the waterproof protrusion 8 and the waterproof recess are easier to install.

[0028] like Figure 3 、 Figure 4 As shown, there are multiple groups of waterproof protrusions 8 and waterproof recesses, and the multiple groups of waterproof protrusions 8 and waterproof recesses on the waterproof cover 5 and the connector 2 are spaced apart and form a wave-like structure. The distance between the waterproof protrusions 8 and the corresponding waterproof recesses is the fitting depth. The fitting depth of the multiple groups of waterproof protrusions 8 and waterproof recesses increases in the direction away from the motor. The fitting depth is as shown in FIG. Figure 4 As shown, when the waterproof protrusion 8 and the waterproof recess on the left side are matched, under such a setting, the middle part of the waterproof cover 5 is made of thicker material and has better strength, while the waterproof protrusion and the waterproof recess on the left side correspond to the waterproof cover 5 with a larger wall thickness, so it is not easy to deform after installation, and thus a triangular-like matching part is formed between the internal whole of the waterproof cover 5 and the outer wall of the connector 2, and the concave-convex matching of the waterproof recess and the waterproof protrusion 8 can further enhance the matching strength and sealing.

[0029] like Figure 4 As shown, a stop portion 9 is formed on the left side of the leftmost waterproof recess on the connector 2. The thickness of the connector 2 increases toward the left side of the stop portion 9 to form a configuration with a low middle and high sides. The corresponding waterproof cover 5 also has an adaptive setting to increase the matching area between the waterproof cover 5 and the connector 2.

[0030] like Figure 4As shown, the structure proposed in this embodiment also includes a mounting base 1, which is connected to the motor body 4. A pressing portion 10 is provided on the outside of the mounting base 1. The pressing portion 10 forms an inner cavity for mounting the connector 2. The inner cavity of the connector 2 is provided with an installation step. After installation, the outer end of the pressing portion 10 and the installation step abut against each other and fit tightly. When the waterproof cover 5 is inserted, the installation step can indicate the installation end point. The abutment and fit between the installation step and the outer end of the pressing portion 10 can effectively form an abutment seal, thereby ensuring the sealing of the interface position here.

[0031] Continue to refer to Figure 4 A buffer mounting portion 11 is provided at the innermost side of the inner cavity of the pressing portion 10. The buffer mounting portion 11 includes an integrally formed mounting section and a buffer section. The mounting section is tightly attached to and sealed against the inner cavity of the pressing portion 10. The buffer section is funnel-shaped. The inner cavity of the pressing portion 10 forms a limiting portion at the connection between the mounting section and the buffer section to fix the mounting section. A deformation space is provided between the buffer section and the inner cavity of the pressing portion 10. During installation, the end of the connector 2 abuts against the end face of the buffer section. The buffer section elastically deforms in the deformation space, and the outer end of the connector 2 is tightly attached to and sealed against the inner cavity of the pressing portion 10. The connector 2 and the buffer section are fixedly connected. They can be fixed by gluing, or they can be integrally formed from the beginning. Of course, they can also be fixed by detachable means such as screws. The buffer installation portion 11 provides buffering and effective sealing for the installation of the connector 2. The installation section mainly provides fixing and sealing functions, the buffer section mainly provides buffering function, and the deformation space provides space for the deformation of the buffer section. At the same time, it also provides an installation environment with good sealing and certain flexible deformation ability when the connector 2 is installed.

[0032] like Figure 3 As shown, the connector 2 is connected to a wire group 3, which includes several wires 6. The waterproof cover 5 is provided with a socket suitable for the wires 6 to pass through. Gluing and other operations to enhance the tightness can be performed on the wires 6 and the sockets.

[0033] The waterproof cover 5 in this embodiment can be an integrated design, with three waterproof protrusions 8 and three waterproof recesses spaced apart within the inner cavity of the waterproof cover 5. The waterproof cover 5 is made of a highly elastic rubber material. During installation, the waterproof protrusions 8 of the waterproof cover 5 and the waterproof protrusions 8 of the connector 2 will deform when they interact, creating a concave-convex fit. Therefore, for smooth installation, the entire waterproof cover 5 is preferably made of a highly elastic rubber material, at least the waterproof protrusions 8 and waterproof recesses within the waterproof cover 5.

[0034] Of course, in order to facilitate installation, the waterproof cover 5 can also be a split design, which includes at least two monomers. The two monomers are detachably fixed after installation, for example, by screws. The split design does not involve the above-mentioned elastic deformation, so the material does not necessarily have to be rubber. The use of rubber material can increase the sealing performance. When other materials are used, the production tolerances of the waterproof protrusions and waterproof recesses are controlled so that they can be relatively tightly fitted together, thereby ensuring better sealing performance.

[0035] In order to ensure the sealing of the wire 6 at the connector 2, the connector 2 is provided with a wire groove for the wire 6 to pass through, and a waterproof pad is provided inside the wire groove through interference fit.

[0036] like Figure 2 、 Figure 4 A stop plate 7 is provided on the mounting base 1, and a drainage groove is formed between the stop plate 7 and the waterproof cover 5. The drainage groove can prevent water from accumulating at the connection between the waterproof cover 5 and the mounting base 1, thereby preventing liquid from seeping in.
