Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an interior rearview mirror and an automobile. Background Technology

[0002] In existing technology, the interior rearview mirror is fixed to the windshield assembly via a mounting base. The mounting base has a ball joint, and the mirror housing has a ball socket. The ball joint and the ball socket cooperate, allowing the mounting base and the mirror housing to rotate relative to each other through friction. In this way, drivers of different heights can adjust the angle of the interior rearview mirror by moving the mirror housing to meet their field of vision needs.

[0003] To ensure the stability of the rearview mirror lens during vehicle operation and prevent shaking, the assembly between the ball joint and the mirror housing must be precise and free of play. However, since the ball joint is typically made of polyoxymethylene (POM), a crystalline engineering plastic, it undergoes secondary crystallization at high temperatures. This secondary crystallization process causes the ball joint to shrink at high temperatures, potentially creating gaps between the ball joint and the mirror housing. Ultimately, this can lead to the rearview mirror becoming loose, affecting its performance and driving safety. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] Reference Figure 1 The first aspect of this utility model provides an interior rearview mirror, including a mirror housing 100, an adjustment ball socket 200, and a connecting rod assembly 300.

[0039] Reference Figure 2 , Figure 6 In one embodiment, one end of the connecting rod assembly 300 is provided with a ball head, which is a circular spherical structure. An adjusting ball socket 200 is disposed inside the mirror housing 100, and the adjusting ball socket 200 has a groove 210 adapted to the shape of the ball head. The ball head is at least partially located in the groove 210, so that the mirror housing 100 can rotate relative to the connecting rod assembly 300.

[0040] Reference Figure 3 , Figure 4 In one embodiment, the adjusting ball socket 200 is provided with limiting hooks 220 on opposite sides along a first direction, each limiting hook 220 including a limiting part 221. The mirror housing 100 is provided with a limiting rib 110 arranged along a second direction, perpendicular to the first direction. In the first direction, the limiting rib 110 engages with the limiting part 221 to limit the adjusting ball socket 200. When the adjusting ball socket 200 undergoes secondary contraction at high temperatures, the engagement of the limiting hooks 220 and the limiting rib 110 restricts the movement of the adjusting ball socket 200, thereby ensuring that the rearview mirror remains relatively stable in high-temperature environments, reducing vibration caused by loosening, and thus guaranteeing performance and driving safety.

[0041] Specifically, the limiting hooks 220 on both sides of the adjusting ball socket 200 and the limiting ribs 110 inside the mirror housing 100 form a fastening connection in the first direction. This ensures that during initial assembly, the adjusting ball socket 200 and the mirror housing 100 are perfectly aligned in the first direction through the cooperation of the limiting part 221 and the limiting rib 110. When the adjusting ball socket 200, made of polyoxymethylene (POM) material, undergoes secondary crystallization shrinkage under high temperature conditions, although the size of the adjusting ball socket 200 will decrease, the constraint relationship between the limiting part 221 of the limiting hook 220 and the limiting rib 110 of the mirror housing 100 in the first direction remains unchanged. The limiting part 221 of the limiting hook 220 and the limiting rib 110 of the mirror housing 100 remain fastened, thus restricting the movement of the adjusting ball socket 200 after shrinkage, maintaining the positional stability of the ball socket within the mirror housing 100, and reducing rearview mirror vibration. Furthermore, since the limiting rib 110 is arranged along the second direction, that is, the arrangement direction of the limiting rib 110 and the limiting hook 220 is perpendicular, the adjusting ball socket 200 cannot move along the first direction when it undergoes secondary crystallization shrinkage, thereby enhancing the stability of the overall structure.

[0042] It should be noted that the first direction is the X direction, and the second direction is the Y direction.

[0043] Reference Figure 4 , Figure 6In one embodiment, the limiting hook 220 further includes a base 222 connected to the limiting part 221, and a limiting groove 223 is formed between the base 222 and the limiting part 221. At least a portion of the limiting rib 110 is disposed within the limiting groove 223, and the sidewall of the limiting part 221 facing the limiting groove 223 abuts against the limiting rib 110, thereby improving structural stability and reliability. Even if high temperature causes the size of the adjusting ball socket 200 to change, the limiting rib 110 can still abut against the limiting hook 220 through the limiting groove 223, thereby ensuring that the adjusting ball socket 200 and the mirror housing 100 have no misalignment in the first direction, ensuring that the rearview mirror lens remains stable during vehicle operation.

[0044] Reference Figure 5 , Figure 6 In one embodiment, the adjusting ball socket 200 is further provided with a first limiting block 230 on both opposite sides along the first direction, and the limiting rib 110 is provided with a second limiting block 120. The first limiting block 230 and the second limiting block 120 are engaged, thereby further limiting the adjusting ball socket 200 and preventing it from loosening. In addition, the first limiting block 230 and the limiting hook 220 are spaced apart, which facilitates limiting the adjusting ball socket 200 in multiple directions.

[0045] Reference Figure 6 , Figure 7 , Figure 8 Specifically, the second limiting block 120 of the limiting rib 110 is arranged along a third direction, which is perpendicular to the first and second directions respectively. The second limiting block 120 includes a vertical part 121 and a horizontal part 122 connected to the vertical part 121. A limiting step 123 is formed between the vertical part 121 and the horizontal part 122. In the third direction, the first limiting block 230 abuts against the limiting step 123, thereby limiting the adjustment ball socket 200 in the third direction. When the POM material adjustment ball socket 200 shrinks secondary due to high temperature, the first limiting block 230 and the second limiting block 120 cooperate to limit the adjustment ball socket 200 in the third direction, thereby stably installing the adjustment ball socket 200 in the lens housing 100 and enhancing the anti-loosening ability of the connection between the adjustment ball socket 200 and the lens housing 100.

[0046] It should be noted that the third direction is the Z direction.

[0047] Reference Figure 6 , Figure 8In one embodiment, a first guide slope 124 is provided on the side of the second limiting block 120 away from the vertical portion 121 on the horizontal portion 122, and a second guide slope 231 is provided on the first limiting block 230 of the adjusting ball socket 200. The first guide slope 124 and the second guide slope 231 cooperate to guide the first limiting block 230 and the second limiting block 120 to engage, making the assembly process smoother, reducing the assembly difficulty and failure rate caused by component misalignment, and improving production efficiency. When the adjusting ball socket 200 is installed with the mirror housing 100, the adjusting ball socket 200 slides along the second guide slope 231 of the second limiting block 120 via the second guide slope 231 of the horizontal portion 122, causing the second limiting block 120 to deform, thereby causing the first limiting block 230 to abut against the limiting step 123, thus realizing the assembly of the adjusting ball socket 200 and the housing.

[0048] Reference Figure 5 , Figure 6 , Figure 9 In one embodiment, the ball joint 200 is further provided with limiting posts 240 on both sides opposite to each other along the first direction. The limiting rib 110 is provided with a mounting groove 130. The limiting posts 240 are disposed in the mounting groove 130, and the side of the limiting posts 240 away from the ball joint 200 abuts against the limiting rib 110. This can further limit the ball joint 200 in the first direction, reduce the loosening or displacement of the ball joint 200, reduce the shaking phenomenon of the rearview mirror, and provide the driver with a stable and clear rear view.

[0049] Reference Figure 5 , Figure 9 In one embodiment, a horizontal rib 140 is provided on the side of the limiting rib 110 away from the limiting part 221. A mounting part 150 is provided on the horizontal rib 140. A mounting groove 130 is formed between the mounting part 150, the horizontal rib 140, and the limiting rib 110, so that after the limiting post 240 is embedded in the mounting groove 130, it can fit tightly against the inner wall of the mounting groove 130 in the first direction to limit the displacement of the adjusting ball socket 200.

[0050] Reference Figure 7 , Figure 9 In one embodiment, a guide block 160 is also provided on the transverse rib 140. The guide block 160 is spaced apart from the mounting part 150. The guide block 160 is used to guide the installation of the limiting post 240, so that the limiting post 240 can slide into the mounting groove 130 along the guide trajectory of the guide block 160, thereby improving assembly efficiency.

[0051] Reference Figure 8 , Figure 9In one embodiment, a support block 170 is provided between the transverse rib 140 and the mirror housing. Specifically, the support block 170 is located on the side of the transverse rib 140 away from the second limiting block 120, and the support block 170 is used to enhance the structural strength of the transverse rib 140. When the adjusting ball socket 200 shrinks due to secondary crystallization of POM material under high temperature, and the force between the limiting hook 220 and the limiting stop rib 110 changes, the support block 170 can enhance the structural strength of the transverse rib 140, thereby enhancing the structural strength of the limiting stop rib 110, avoiding limiting failure due to deformation of the limiting stop rib 110, and further consolidating the limiting effect of the adjusting ball socket 200, ensuring that the interior rearview mirror is always in a stable working state.

[0052] A second aspect of this utility model provides a car including an interior rearview mirror as described in the first aspect of this utility model. The interior rearview mirror can remain relatively stable in high-temperature environments, reducing vibrations caused by loosening of the interior rearview mirror, thereby ensuring performance and driving safety.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
