Description

Technical Field

[0001] The invention relates to the technical field of an inner rearview mirror bracket, and more particularly to an adjustable structure of an inner rearview mirror ball head bracket. Background Art

[0002] In existing cars, the field of view of the rearview mirror inside the car is usually adjusted by connecting a ball head with a ball head fixing bracket. Due to different car manufacturers and different car models, the rearview mirror brackets in the car interior have various shapes and specifications, and the size of the ball head is configured with different wiring harnesses according to the function of the rearview mirror, so the ball head fixing bracket has poor versatility.

[0003] The ball head fixing mechanism in the prior art is usually a plastic claw-shaped structure that wraps around the ball head, or a clamp (or a clamp ring) is added to the periphery of the plastic claw-shaped structure to fix it. The ball head that can be installed in this way is unique in size, cannot be adjusted, and has poor versatility.

[0004] Another method is to make a plastic claw-shaped ring structure that can cover the ball head, and add a tight metal ring on the outside. When the ball head is inserted, the tight metal ring limits the outward expansion of the ball head matching structure, allowing the two to be connected smoothly. However, the disadvantage of this method is that there are many scattered parts, and multiple guide groove structures need to be designed, which makes assembly and disassembly inconvenient.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an adjustable structure for an interior rearview mirror ball head bracket, which adjusts the tensioning force of the claws by setting a straight-grained nut so that the claws can clamp ball heads of different sizes, thereby improving applicability.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: an adjustable structure of an interior rearview mirror ball head bracket, comprising an outer shell body for mounting the interior rearview mirror and a mounting bracket for mounting the outer shell body, the mounting bracket is fixedly connected with a spherical protrusion on one side close to the outer shell body, the inner wall of the outer shell body is fixedly connected with a mounting seat, the outer shell body is provided with a through hole for inserting the spherical protrusion, the mounting seat is provided with a spherical groove for inserting the spherical protrusion, the inner wall of the spherical groove is fixedly connected with a claw, a limiting mechanism is provided on the outer wall of the claw, and the claw encloses a covering cavity for fixing the spherical protrusion.

[0008] By adopting the above technical solution, the spherical protrusion on the mounting bracket is inserted into the covering cavity and the spherical groove, the spherical protrusion is wrapped by the spherical groove and the covering cavity, and then the tightness of the claw is adjusted by the limiting mechanism outside the claw to fix the spherical protrusion by the claw. In this way, the connection between the mounting bracket and the outer shell can be achieved, and the outer shell can be rotated with the mounting bracket through the spherical protrusion. While ensuring that the outer shell can be adjusted in angle, the claw can fix ball heads of different sizes, which has better versatility and a wider range of applications.

[0009] The present invention is further configured as follows: the limiting mechanism includes a straight-grained nut sleeved on the outer wall of the clamping claw, and the outer wall of the clamping claw is provided with an external thread that is matched with the straight-grained nut thread.

[0010] By adopting the above technical solution, the tightness of the clamping claw can be adjusted by the fingerprint nut, the structure is simple, and the clamping claw can be suitable for the installation of spherical protrusions of different sizes.

[0011] The present invention is further configured as follows: the clamping claw is arranged at an angle, and one end of the clamping claw away from the mounting seat is inclined toward the axial direction of the spherical groove.

[0012] By adopting the above technical solution, the inclined claw will be closed at one end of the mounting seat, so that the fixation of the spherical protrusion is more stable and the covering effect is better.

[0013] In summary, the present invention has the following beneficial effects:

[0014] The tension of the clamping claw is adjusted by setting a straight-thread nut. While ensuring that the outer shell can be adjusted in angle, the clamping claw can fix ball heads of different sizes, which has better versatility and a wider range of applications.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The present invention is described in detail below in conjunction with the accompanying drawings.

[0023] An adjustable structure of the ball head bracket of an interior rearview mirror, such as Figure 1-Figure 3 As shown, it includes an outer shell 1 for mounting an interior rearview mirror and a mounting bracket 2 for mounting the outer shell 1, a spherical protrusion 3 is fixedly connected to the side of the mounting bracket 2 close to the outer shell 1, a mounting seat 4 is fixedly connected to the inner wall of the outer shell 1, a through hole 5 for the spherical protrusion 3 to be inserted is provided on the outer shell 1, and a spherical groove for the spherical protrusion 3 to be inserted is provided on the mounting seat 4;

[0024] A claw 6 is fixedly connected to the inner wall of the spherical groove, and a limiting mechanism is provided on the outer wall of the claw 6. The claw 6 encloses a covering cavity for fixing the spherical protrusion 3. The limiting mechanism includes a straight-grained nut 7 sleeved on the outer wall of the claw 6, and the outer wall of the claw 6 is provided with an external thread that is threadably connected to the straight-grained nut 7.

[0025] The claw 6 is arranged at an angle, and the fingerprint nut sleeved on the outer wall of the claw 6 maintains the same inclination angle as the claw 6. The end of the claw 6 away from the mounting seat 4 is inclined toward the axial direction of the spherical groove.

[0026] The spherical protrusion 3 on the mounting bracket 2 is inserted into the covering cavity and the spherical groove, the spherical protrusion 3 is wrapped by the spherical groove and the covering cavity, and then the tightness of the claw 6 is adjusted by the limiting mechanism outside the claw 6 to fix the spherical protrusion 3 by the claw 6. In this way, the mounting bracket 2 and the outer shell 1 can be connected, and the outer shell 1 can be rotated with the mounting bracket 2 through the spherical protrusion 3. While ensuring that the outer shell 1 can be adjusted in angle, the claw 6 can fix ball heads of different sizes, which has better versatility and a wider range of applications.

[0027] Among them, when it is necessary to adjust the tightness of the claw 6 through the fingerprint nut, first, the straight-grained nut 7 can be directly moved to the side close to the mounting seat 4. Since the inner wall of the straight-grained nut 7 and the claw 6 are both inclined, the movement of the straight-grained nut 7 can control the tightening of the claw 6, so that the claw 6 can fix the spherical protrusion 3 with a smaller diameter. Similarly, when the straight-grained nut 7 moves in the opposite direction and away from the mounting seat 4, the claw 6 will be loosened, so that the spherical protrusion 3 with a larger diameter can be installed. In addition, the straight-grained nuts 7 with different inner diameters can be directly replaced to adjust the tightness of the claw 6 to achieve the installation of spherical protrusions 3 of different sizes. The structure is simple, and the claw 6 can be suitable for the installation of spherical protrusions 3 of different sizes.

[0028] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
