[0002] In the assembly process of automotive rearview mirrors, a high-precision ball joint and bearing connection device is required to achieve universal adjustment.

[0003] The existing rearview mirror ball joint and axle connection device has obvious defects in connection stability and functional reliability. Because it requires wiring and power supply, the inside of the ball joint rod is hollowed out to accommodate the connecting wire, which makes it impossible to set an angle limiting structure. When rotating at the extreme angle or with force, the ball joint is prone to detach from the rearview mirror body and may even break the connecting wire, causing functional failure. This design not only affects the user experience and damages the brand reputation, but also poses a hidden danger of insufficient structural stability. The lack of limiting structure and functional protection in the equipment restricts the reliability of the rearview mirror connection device and the user's trust. Utility Model Content

[0004] In view of the problems existing in the above-mentioned internal rearview mirror ball joint and bearing connection device, this utility model is proposed.

[0005] Therefore, the problem that this utility model aims to solve is that the large rotation limit makes it easy for the connecting wire to be broken due to excessive rotation.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1

[0023] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a device for connecting the ball head and the axle of an interior rearview mirror. The device for connecting the ball head and the axle of an interior rearview mirror includes a fixing component 1 and a connecting component 2.

[0024] Through the coordinated optimization of fixing component 1 and connecting component 2, the obvious defects such as the lack of limiting function and the easy damage of connecting wires caused by hollowing out the ball head mirror rod for threading are effectively solved. Not only is the threading function maintained, but a hidden angle limiting component is also embedded to accurately limit the rotation range of the ball head to avoid the risk of extreme disengagement. The design bottleneck is broken through from the dual levels of limiting reliability and functional protection. This not only improves the operational stability and structural safety of the interior rearview mirror connection device, but also enhances user confidence by eliminating potential hazards. It provides key technical support for the reliability upgrade of the vehicle mirror assembly connection system and the guarantee of brand reputation.

[0025] Specifically, the fixing component 1 includes a fixing bracket 11, a mirror rod 15 is embedded on one side of the fixing bracket 11, and a mounting groove 12 is opened on one side of the fixing bracket 11.

[0026] Specifically, the connecting component 2 is disposed on one side of the fixing component 1, including a ball seat 21 disposed on one side of the fixing component 1, a fixing frame 22 fixed on the surface of the ball seat 21, a ball head 24 disposed on one side of the ball seat 21, and a toggle block 26 fixed on one side of the fixing frame 22.

[0027] Example 2

[0028] Reference Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] Specifically, a through hole 13 is provided on the surface of the lens rod 15, and a threading hole 14 that mates with the through hole 13 is provided on the lens rod 15.

[0030] The through hole 13 and the wire hole 14 are interconnected to form a circuit channel, which facilitates the connection wire 23 to pass through the mirror rod 15 and avoids the wire from being exposed and causing wear or tangling. The two work together to hide and protect the wire, ensuring that the wire layout is neat, while not affecting the structural strength of the mirror rod 15.

[0031] Specifically, the connecting component 2 also includes a connecting wire 23 disposed in the inner cavity of the wire hole 14, the connecting wire 23 extending into the inner cavity of the through hole 13.

[0032] The connecting wire 23 passes through the wire hole 14 and the through hole 13 through the mirror rod 15 to realize the electrical signal or data connection between the components at both ends of the mirror rod. The channel layout avoids the connecting wire being pulled by external force, ensures stable transmission, and facilitates the later maintenance or replacement of the connecting wire.

[0033] Specifically, the connecting component 2 also includes a retaining ring 25 fixed to one side of the ball seat 21, and the surface of the ball head 24 is movably connected to the inner wall of the retaining ring 25.

[0034] The retaining ring 25 provides elastic restraint to the ball head 24, allowing the ball head 24 to rotate flexibly within the ball seat 21 to adjust the angle, while preventing the ball head 24 from falling out of the ball seat 21. The elastic constraint balances flexibility and stability, ensuring the reliable adjustment function of the connecting assembly 2.

[0035] Specifically, the ball head 24 is fixed to one side of the mirror rod 15.

[0036] The fixed connection between the ball head 24 and the mirror rod 15 allows the mirror rod 15 to rotate within the ball seat 21 with the ball head 24, enabling multi-angle adjustment of the rearview mirror. The fixed structure ensures that the ball head 24 can stably drive the mirror rod 15 to move synchronously, preventing loosening during adjustment and ensuring the stability of the angle after adjustment.

[0037] During use and installation, the ball head 24 of the connecting component 2 is embedded in the inner cavity of the ball seat 21. The ball seat 21 wraps around the ball head 24 to achieve initial engagement. The retaining spring 25 on one side of the ball seat 21 presses the edge of the ball seat 21, so that the ball head 24 and the ball seat 21 are tightly connected in the normal state. The fixing bracket 22 and the actuating block 26 assist the ball seat 21 in positioning and installation with the fixing bracket 11 of the fixing component 1.

[0038] When the user rotates the mirror rod 15 to adjust the rearview mirror angle, the mirror rod 15 drives the ball head 24 to rotate relative to the ball seat 21. The surface of the ball head 24 slides along the inner wall of the ball seat 21 to meet the multi-angle adjustment requirements. The connecting wire 23 in the wire hole 14 and the through hole 13 moves adaptively with the rotation of the mirror rod 15.

[0039] As the rotation angle increases, the newly added limiting step surface of the ball head 24 gradually approaches the ball seat 21. When the limit angle is reached, the limiting step surface contacts the inner wall of the ball seat 21 to form "contact point one". At the same time, the other side of the ball seat 21 contacts the surface of the mirror rod 15 to form "contact point two". The two contact points together constitute a mechanical limit, preventing the ball head 24 from continuing to rotate.

[0040] This limiting structure prevents the ball head 24 from detaching from the ball seat 21, while limiting the rotation angle of the mirror rod 15. It also prevents the connecting wire 23 in the wire hole 14 and through hole 13 from being excessively pulled or squeezed, ensuring stable power supply. Users can adjust the angle freely within a safe range without worrying about excessive rotation causing detachment or damage.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
