[0038] See also Figure 1-3 9, the utility model provides a vehicle component integration structure, including a rear windshield 1, a mounting seat 2, a back door switch 22, a rear wiper 3 and a waterproof ring 4; the rear windshield 1 is provided with a mounting hole 11; the mounting seat 2 is fixed to the outer side of the rear windshield 1, and the mounting seat 2 is provided with a positioning through hole 21; the back door switch 22 is installed on the mounting seat 2; the rear wiper 3 includes a wiper shaft assembly 31, and one end of the wiper shaft assembly 31 passes through the positioning through hole 21 and the mounting hole 11; the waterproof ring 4 is sleeved on the outside of the wiper shaft assembly 31 and annularly seals the mounting hole 11 and the positioning through hole 21, and the wiper shaft assembly 31 is fixed to the mounting hole 11 and the positioning through hole 21 through the waterproof ring 4.

[0039] It should be noted that the rear windshield of the automobile is referred to as the rear windshield 1, and the mounting hole 11 is a hole reserved when the rear windshield 1 is manufactured; the outer side of the rear windshield 1 is the side of the rear windshield 1 facing the outside of the vehicle, and the inner side of the rear windshield 1 is the side of the rear windshield 1 facing the inside of the vehicle. Among them, the mounting seat 2, the back door switch 22 and the waterproof ring 4 can be integrated into a back door switch assembly to form a separate product, and then integrated with the rear windshield 1 and the rear wiper 3. The waterproof ring 4 is installed in the mounting seat 2 and is adapted to be installed and fixed with the internal cavity of the mounting seat 2; the mounting seat 2 can be bonded and connected to the rear windshield 1 by itself, or the mounting seat 2 can be bonded and fixed to the outer side of the rear windshield 1 through the waterproof ring 4; the mounting seat 2 is provided with a positioning through hole 21, and the positioning through hole 21 is passed through by the wiper shaft assembly 31 to realize the installation and positioning of the mounting seat 2 itself, solving the installation and positioning problem of the mounting seat 2. The back door switch 22 is an electric switch, which can be controlled by a wired connection controller or by a wireless connection controller. A cavity can be provided in the mounting seat 2 to install and protect the back door switch 22, and the button formed by the back door switch 22 protrudes from the mounting seat 2, so as to facilitate manual pressing of the back door switch 22 for control. The structure of the waterproof ring 4 near the positioning through hole 21 during installation is adapted to the positioning through hole 21, the structure of the waterproof ring 4 near the mounting hole 11 during installation is adapted to the mounting hole 11, the portion of the waterproof ring 4 in contact with the mounting seat 2 is adapted to the surface shape of the mounting seat 2, the structure of the waterproof ring 4 in contact with the rear windshield 1 is adapted and sealed with the rear windshield 1, and the waterproof ring 4 can be made of waterproof rubber material or ethylene propylene diene monomer rubber (EPDM) or thermoplastic elastomer (TPE) or other materials that meet the use requirements. Originally, when the rear wiper 3 is installed separately, when the wiper shaft assembly 31 passes through the mounting hole 11, it is necessary to make a waterproof structure at the mounting hole 11. Now, by installing the mounting seat 2 at the mounting hole 11, the axial length of the mounting hole 11 can be increased and the radial area waterproof protection of the mounting hole 11 can be increased, thereby increasing the waterproof effect of the rear wiper 3 to a certain extent; secondly, by the provision of the waterproof ring 4, the waterproof ring 4 is sleeved on the outer circumferential surface of the wiper shaft assembly 31, and the mounting hole 11 and the positioning through hole 21 are sealed by the waterproof ring 4. Compared with the original waterproofing of only the mounting hole 11, the vehicle component integrated structure can further improve the waterproof performance of the mounting hole 11 of the rear windshield 1.In addition, before the improvement, the wiper shaft assembly 31 of the rear wiper 3 is connected to the mounting seat 2. Due to the dimensional chain tolerances along the axial and radial directions of the wiper shaft assembly 31 when the wiper shaft assembly 31 is assembled, a part of the axial and radial forces of the wiper shaft assembly 31 will directly act on the mounting seat 2, which can easily cause the mounting seat 2 to fall off due to the force, thereby affecting the use of the tailgate switch 22 on the mounting seat 2 and the waterproof performance of the mounting hole 11 of the rear windshield 1. Therefore, in this case, the wiper shaft assembly 31 is not directly in contact with the mounting seat 2, but is fixed in the mounting hole 11 and the positioning through hole 21 through the waterproof ring 4, so that the axial and radial forces generated by the wiper shaft assembly 31 are at least partially offset and buffered by the waterproof ring 4, thereby enabling the mounting seat 2 to be stably installed on the rear windshield 1, and also ensuring the waterproof performance of the mounting hole 11 of the rear windshield 1.

[0040] See also Figure 1-3 and 9, as an optional embodiment of the present invention, the wiper shaft assembly 31 includes a wiper shaft 311 and a shaft sleeve 312 rotatably sleeved outside the wiper shaft 311;

[0041] The outer ring of the waterproof ring 4 includes an annular clamping portion 41 , and the annular clamping portion 41 is interference-fitted into the mounting hole 11 . The inner ring of the waterproof ring 4 is interference-fitted with the outer circumferential surface of the shaft sleeve 312 .

[0042] It should be noted that the shaft sleeve 312 is rotatably connected to the wiper shaft 311, and the shaft sleeve 312 is fixedly connected or interference-fitted with the waterproof ring 4 to improve the waterproof performance; by providing an annular clamping portion 41 on the outer ring of the waterproof ring 4, and making the waterproof ring 4 interference-fit in the mounting hole 11, the bottom 411 and both sides of the annular clamping portion 41 of the waterproof ring 4 are interference-fitted with the rear windshield 1 structure at the edge of the mounting hole 11, thereby sealing the mounting hole 11, improving the waterproof performance, and buffering the deflection force transmitted from the wiper shaft assembly 31.

[0043] See also Figure 1-3 And 9, as an optional embodiment of the present case, at least one circle of annular protrusions 42 are provided in the inner ring of the waterproof ring 4; the annular protrusions 42 are assembled to be at least adjacent to the inner side of the rear windshield 1, and the annular protrusions 42 are interference fit with the outer circumferential surface of the sleeve 312.

[0044] It should be noted that at least one annular protrusion 42 is provided on the inner ring of the waterproof ring 4 to enhance the sealing between the inner ring of the waterproof ring 4 and the shaft sleeve 312; the annular protrusion 42 is assembled to be at least adjacent to the inner side of the rear windshield 1, and the annular protrusion 42 can also be completely located on the inner side of the rear windshield 1. The reason why the annular protrusion 42 is assembled adjacent to the inner side of the rear windshield 1 and the annular protrusion 42 and the outer circumferential surface of the shaft sleeve 312 are interference fit is that due to the redundant design of the tolerance of the long dimension chain of the vehicle body, the wiper shaft assembly 31 has an axial deviation to the outside of the rear windshield 1 during assembly, and when passing through the mounting hole 11 and the positioning through hole If it is connected to the mounting base 2 at 21, there will be a deflection force acting on the mounting base 2. Therefore, through the setting of the annular protrusion 42, the waterproof ring 4 can offset and correct the deflection force generated by the wiper shaft assembly 31 under the resistance of the rear windshield 1. The annular protrusion 42 is located on the inner side of the rear windshield 1, which can just offset the axial deflection force at least in the reverse direction. Most of the deflection force is transferred to the rear windshield 1 by matching the tolerance of the long dimension chain of the vehicle body with the tailgate switch 22, thereby avoiding affecting the installation stability of the mounting base 2 and the tailgate switch 22 on the mounting base 2 and the leakage problem caused by the installation of the mounting base 2 falling off.

[0049] It should be noted that the side of the annular snap-fit ​​portion 41 close to the rear windshield 1 is a circle of barbs 412, and the circle of barbs 412 can be fitted on the inner side of the rear windshield 1. Since the circle of barbs 412 and the rear windshield 1 are interference fit, the waterproof performance between the waterproof ring 4 and the rear windshield 1 can be further improved.

[0050] See also Figure 3-5 As an optional embodiment of the present case, a circle of annular recess is provided on one side of the annular engaging portion 41 which is in contact with the inner side of the rear windshield 1, and the annular recess is provided adjacent to the barb 412, and the annular recess is configured so that when the annular engaging portion 41 is interference fit in the mounting hole 11, a circle of negative pressure cavity 413 is formed between the annular recess and the inner side of the rear windshield 1, that is, a circle of negative pressure cavity 414 is formed between the annular engaging portion 41 and the inner side of the rear windshield 1.

[0051] It should be noted that, by providing the negative pressure cavity 413, it can be ensured that the barb 412 can be in contact with the rear windshield 1 for a long time and there is pressure, thereby further improving the waterproofness between the waterproof ring 4 and the rear windshield 1; that is, there are three layers of waterproofing between the waterproof ring 4 and the rear windshield 1 in this case, the bottom surface 23 of the mounting seat 2 is bonded to the outer side of the rear windshield 1 to form a first layer of waterproofing, the bottom 411 of the annular clamping portion 41 is interference fit with the hole wall of the mounting hole 11 to form a second layer of waterproofing, a circle of barbs 412 is interference fit with the inner side of the rear windshield 1, and a circle of negative pressure cavity 413 is formed between the barbs 412 and the rear windshield 1, which ensures the contact between the waterproof ring 4 and the rear windshield 1, forming a third layer of waterproofing, and the waterproofing level is relatively high.

[0052] See also Figure 1-3 Or 5, as an optional embodiment of the present case, the inner ring of the waterproof ring 4 is provided with at least one annular protrusion 43 which abuts against the outer circumferential surface of the sleeve 312, and the annular protrusion 43 is arranged with interference fit with the sleeve 312.

[0053] It should be noted that at least one annular protrusion 43 is disposed on the outer side of the rear windshield 1 , and an interference fit is provided between the annular protrusion 43 and the shaft sleeve 312 to provide a first layer of waterproofing and dustproofing between the waterproof ring 4 and the shaft sleeve 312 .

For example, the lower part of the mounting seat 2 is integrally formed with the waterproof ring 4, and when the annular protrusion 43 on the upper part of the waterproof ring 4 is assembled in the positioning through hole 21, it is convenient for the matching installation between the lower part and the upper part of the mounting seat 2, and the lower part and the upper part of the mounting seat 2 can be fastened by screws; wherein, the bottom surface 23 is located at the lower part of the mounting seat 2. For example, the mounting seat 2 and the waterproof ring 4 are two-color injection molded, wherein two-color injection molding is a manufacturing method that uses two different materials of plastic and completes injection molding in the same set of molds through a special molding process. In this case, by integrating the mounting seat 2 and the waterproof ring 4, on the one hand, the connection strength between the mounting seat 2 and the waterproof ring 4 can be enhanced, and on the other hand, the sealing of the connection between the two can be enhanced, the waterproof effect can be improved, and rainwater can be prevented from penetrating from the gap between the two to the inner side of the rear windshield 1, thereby further improving the waterproof effect of the vehicle component integrated structure.
