[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 3-4 As shown, the front wiper motor rubber sleeve of the utility model comprises a rubber sleeve body 1, wherein the rubber sleeve body 1 is provided with a socket 2 for inserting a connecting plate, wherein the socket 2 has an outer convex side and an inner concave side on a cross section perpendicular to the insertion direction of the connecting plate, and the outer convex side of the socket 2 is provided with an inner slot 3 for clamping with the connecting plate of the front wiper motor, and the side wall of the inner slot 3 near the opening of the socket 2 is provided with a stop surface 5.

[0020] The inventor found in actual operation that when the inner slot 3 is set on the concave side of the connecting plate and the plug hole 2, it is difficult to insert the protrusion 4 of the connecting plate into the inner slot 3 of the plug hole 2, and the problem of not being inserted into place often occurs. After the inventor explored the reason, it was mainly because the concave side of the connecting plate and the plug hole 2 of the rubber sleeve were not in close contact during the installation operation, and the height of the protrusion 4 could not be too large, and the rubber sleeve had a certain flexibility, which made it difficult for the protrusion 4 of the connecting plate to be inserted into the inner slot 3 of the plug hole 2. In the present application, the inner slot 3 is set on the convex side of the plug hole 2, and the protrusion 4 on the connecting plate is also located on its convex side. During the installation of the rubber sleeve, it is easier to insert the protrusion 4 on the connecting plate into the inner slot 3 of the plug hole 2, and it can also be better determined that the protrusion 4 on the connecting plate has been correctly inserted into the inner slot 3 of the plug hole 2. Under the action of the stop surface 5, the rubber sleeve can be prevented from falling off.

[0021] During the process of inserting the connecting plate into the socket 2, it is necessary to ensure that the protrusion 4 is correctly inserted into the inner slot 3, and it is also necessary to ensure that the protrusion 4 is accurately aligned with the inner slot 3. The accuracy of the protrusion 4 being inserted can be improved by increasing the cross-sectional size of the inner slot 3. However, increasing the cross-sectional size of the inner slot 3 will reduce the stability of the installation of the rubber sleeve. Therefore, in one embodiment of the present application, the inner wall of the socket 2 outside the inner slot 3 is provided with a guide groove 6 for guiding the protrusion 4 on the connecting plate, and the two ends of the guide groove 6 are respectively connected to the opening of the socket 2 and the inner slot 3. When the connecting plate is inserted into the socket 2, the protrusion 4 on the connecting plate is aligned with the guide groove 6 at the opening of the socket 2. Under the action of the guide groove 6, the protrusion 4 can accurately enter the inner slot 3, thereby further reducing the difficulty of installing the rubber sleeve.

[0022] In addition, in order to make the protrusion 4 enter the guide groove 6 more smoothly, in the preferred embodiment of the present application, a first inclined surface 7 inclined along the insertion direction of the plug hole 2 is provided at the position corresponding to the inner card slot 3 at the entrance of the plug hole 2, and the guide slot 6 is connected to the first inclined surface 7. The protrusion 4 on the connecting plate is aligned with the first inclined surface 7 of the plug hole 2, and pressed, so that the protrusion 4 can smoothly enter the guide groove 6, and under the guidance of the guide groove 6, further enter the inner card slot 3.

[0023] Based on the front wiper motor rubber sleeve, such as Figure 1-4As shown, the present application also provides a front wiper motor mounting assembly, which includes a connecting plate and the front wiper motor rubber sleeve, the connecting plate includes a plate body 8, the plate body 8 has an insertion end, the insertion end has an outer convex side and an inner concave side, the outer convex side of the insertion end is provided with a protrusion 4, the insertion end is inserted into the insertion hole 2 of the front wiper motor rubber sleeve, and the protrusion 4 is inserted into the inner card groove 3. The front wiper motor mounting assembly of the present application sets the inner card groove 3 on the outer convex side of the insertion hole 2, and the protrusion 4 on the connecting plate is correspondingly located on its outer convex side. During the operation of installing the rubber sleeve, it is easier to make the protrusion 4 on the connecting plate inserted into the inner card groove 3 of the insertion hole 2, and it is also better to determine that the protrusion 4 on the connecting plate has been correctly inserted into the inner card groove 3 of the insertion hole 2. Under the action of the stop surface 5, the rubber sleeve can be prevented from falling off.

[0024] In one embodiment of the present application, a guide groove 6 for guiding the protrusion 4 on the connecting plate is provided on the inner wall of the plug hole 2 outside the inner card slot 3, and the two ends of the guide groove 6 are respectively connected to the opening of the plug hole 2 and the inner card slot 3, and the protrusion 4 is inserted into the inner card slot 3 through the guide groove 6. When the connecting plate is inserted into the plug hole 2, the protrusion 4 on the connecting plate is aligned with the guide groove 6 at the opening of the plug hole 2, and under the action of the guide groove 6, the protrusion 4 can accurately enter the inner card slot 3, thereby further reducing the difficulty of installing the rubber sleeve.

[0025] The connecting plate can be formed by stamping or casting. If the connecting plate is formed by stamping, the protrusion 4 can be formed by the connection plate being stamped and tilted. This method is more convenient to process, but the protrusion 4 cannot form a vertical surface corresponding to the stop surface 5 of the plug hole 2. In another embodiment of the present application, the protrusion 4 includes a second inclined surface facing the outside of the insertion end and a positioning surface facing the inside of the insertion end. The stop surface 5 is perpendicular to the extension direction of the plug hole 2, and the positioning surface abuts against and is parallel to the stop surface 5. The abutment between the positioning surface and the stop surface 5 can prevent the stop surface 5 of the rubber sleeve from being damaged, thereby preventing the rubber sleeve from falling out.
