Abstract

A shock absorbing structure includes: a housing having an opening, an inner surface and an outer surface; a universal joint unit having a spherical joint, a bushing having a blocking plate and a convex piece, and a screw bolt; a shock absorbing ring sheathing a portion of the convex piece protruding from the housing and elastically abutting between the outer surface and the spherical joint; and a clamping claw disposed on the housing and covering the inner surface and the blocking plate. When the clamping claw is applied with an external force to move the housing toward the universal joint unit, the shock absorbing ring generates an elastic deformation to absorb an impact force.

Description

BACKGROUND OF THE DISCLOSURE Technical Field The present disclosure relates to a mobile phone holder, especially to a shock absorbing structure of a mobile phone holder. Description of Related Art With the electronic technology being rapidly developed, a mobile phone has become one of the necessary electronic devices for consumers. Peripheral produces relative to the mobile phone has also been available in the market, wherein a related-art mobile phone holder is commonly used on various occasions. The related-art mobile phone holder clamps a mobile phone by a clawing manner to make the mobile phone be fastened with a fastening seat. Some mobile phone holders are provided with a multi-staged linkage or a universal joint between the mobile phone holder and the fastening seat to adjust the angle and the location of the mobile phone holder, thus various operating environments required by consumers are satisfied. However, no matter the mobile phone holder is the fixed type or has the multi-staged linkage or the universal joint, a shock absorbing structure is not provided to the mobile phone holder. When the mobile phone holder or the mobile phone is subjected to an impact, a collision or a shock, the impact force is directly transferred to the fastening seat of the mobile phone holder and the mobile phone holder may be damaged after being used for a period of time, the aforesaid problem mostly happens when the mobile phone holder is installed on a motorcycle or a car. Accordingly, the applicant of the present disclosure has devoted himself for improving the mentioned shortages. SUMMARY OF THE DISCLOSURE The present disclosure is to provide a shock absorbing structure of a mobile phone holder, which has an advantage of preventing an impact force from being directly transferred to a universal joint unit, and protecting the mobile phone holder from being damaged. Accordingly, the present disclosure provides a shock absorbing structure of a mobile phone holder, which includes a housing, a universal joint unit, a shock absorbing ring and a clamping claw. The housing has an opening, an inner surface and an outer surface, wherein the opening is in communication with the inner surface and the outer surface. The universal joint unit includes a spherical joint, a bushing and a screw bolt. The bushing includes a blocking plate and a convex piece. The convex piece passes through the opening. The blocking plate abuts against the inner surface. The screw bolt passes through the convex piece and is screwed and fastened with the spherical joint. The shock absorbing ring sheathes at a portion of the convex piece which protrudes from the housing, and elastically abuts between the outer surface and the spherical joint. The clamping claw is disposed on the housing and covers the inner surface and the blocking plate. When the clamping claw is applied with an external force to move the housing toward the universal joint unit, the shock absorbing ring generates an elastic deformation to absorb an impact force. According to one embodiment of the present disclosure, the shock absorbing ring is substantially formed in a ball shape, the shock absorbing ring has a truncated opening, and the truncated opening abuts against the spherical joint. According to one embodiment of the present disclosure, the spherical joint includes a connecting seat and a ball part, the connecting seat has a screw hole allowing the screw bolt to be screwed in and fastened, and the ball part is disposed at one side of the connecting seat away from the screw hole. According to one embodiment of the present disclosure, the connecting seat has a step, the step surrounds the screw hole, and the shock absorbing ring elastically abuts against the step. According to one embodiment of the present disclosure, the spherical joint has a position limiting recess, and one end of the convex piece away from the blocking plate is disposed in the position limiting recess. According to one embodiment of the present disclosure, a shape of the convex piece is corresponding to a shape of the opening.
