Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to a manual mirror driver for a rearview mirror of an automobile. Background Art

[0002] At present, the manual mirror driver of the automobile rearview mirror is mainly composed of a base and a floating ring. A ball socket is provided on the base, and an arc-shaped spherical surface is provided on the floating ring. The spherical surface on the floating ring is pressed into the ball socket on the base by a compression spring, so that a sufficiently large friction force is generated between the floating ring and the base. The friction force is used to maintain the position of the floating ring after rotating to an appropriate angle, thereby ensuring the stability of the angle of the mirror. However, the direction of the existing ball socket and the spherical surface is difficult to control when adjusting, and the guidance of the current manual mirror driver of the automobile rearview mirror needs to be improved during adjustment. Summary of the invention

[0003] The embodiment of the present application provides a manual mirror driver for a car rearview mirror. A guide piece is provided between the arc-shaped spherical surface and the ball socket, thereby enhancing the controllability of the direction during manual adjustment. The setting direction of the first guide groove and the setting direction of the second guide groove are perpendicular to each other and do not affect the adjustment of the rearview mirror. A plurality of first guide strips and second guide strips are protrudingly provided, thereby increasing the friction between the arc-shaped spherical surface and the guide piece, and between the ball socket and the guide piece.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manual mirror driver for a rearview mirror of an automobile, the mirror driver comprising a base, a floating ring, a clamping spring, and a connecting shaft body, the base and the floating ring are connected by the connecting shaft body, the clamping spring is arranged around the connecting shaft body and clamps the base and the floating ring, a ball socket is arranged at the upper end of the base, an arcuate spherical surface is arranged at the lower end of the floating ring, the arcuate spherical surface is arranged inside the ball socket, a guide member is arranged between the arcuate spherical surface and the ball socket, a plurality of first guide grooves are arranged at the upper end of the guide member, a first guide strip matched with the first guide groove is protruded from the lower end of the arcuate spherical surface, a plurality of second guide grooves perpendicular to the setting direction of the first guide groove are arranged at the lower end of the guide member, and a second guide strip matched with the second guide groove is protruded from the upper end of the ball socket.

[0005] Compared with the prior art, the advantages of the utility model are:

[0006] A guide piece is provided between the arc-shaped spherical surface and the ball socket. When the rearview mirror of the automobile is manually adjusted, the first guide groove and the first guide strip cooperate with each other to guide in a direction consistent with the setting direction of the first guide groove, and the second guide groove and the second guide strip cooperate with each other to guide in a direction consistent with the setting direction of the second guide groove, thereby enhancing the controllability of the direction during manual adjustment.

[0007] Since the first guide groove is arranged in a direction perpendicular to the second guide groove, the adjustment of the rearview mirror in four directions, i.e., up, down, left, and right, is not affected when there is a guide.

[0008] Compared with the arcuate spherical surface and ball socket in the prior art, since the arcuate spherical surface is protruded with a plurality of first guide strips that cooperate with the first guide groove, and the ball socket is protruded with a plurality of second guide strips that cooperate with the second guide groove, the contact area between the arcuate spherical surface and the guide member, and the ball socket and the guide member is increased, thereby increasing the friction between the arcuate spherical surface and the guide member, and the ball socket and the guide member.

[0009] As an improvement, a limit block is provided at the upper end of the connecting shaft, the upper end of the compression spring abuts against the lower end of the limit block, and the lower end of the compression spring abuts against the upper end of the arc-shaped spherical surface. By abutting the upper end of the compression spring against the lower end of the limit block and the lower end of the compression spring against the upper end of the arc-shaped spherical surface, the compression spring is in a compressed state, further compressing the arc-shaped spherical surface and the ball socket.

[0010] As an improvement, the floating ring is provided with a plurality of first through holes along the central circumference, and the base is provided with second through holes corresponding to the first through holes along the central circumference. Bolts pass through the first through holes and the second through holes to connect with the rearview mirror base. The mirror driver is connected to the rearview mirror base by passing the bolts through the first through holes and the second through holes.

[0011] As an improvement, the arc spherical surface is provided with a third through hole, the guide member is provided with a fourth through hole, and the ball socket is provided with a fifth through hole. The lower end of the connecting shaft passes through the third through hole, the fourth through hole, and the fifth through hole to abut against the lower end of the base. The ball socket, the arc spherical surface and the guide member are connected by passing the lower end of the connecting shaft through the third through hole, the fourth through hole, and the fifth through hole to abut against the lower end of the base.

[0012] As an improvement, a plurality of slots are provided at the lower end of the base, and a block matching the slots is circumferentially provided on the side wall of the lower end of the connecting shaft. The matching between the slots and the blocks facilitates the disassembly and installation of the connecting shaft, thereby facilitating the disassembly and installation of the ball socket, the arc spherical surface and the guide part.
