Description

Technical Field

[0001] The utility model belongs to the field of in-vehicle brackets for electronic products, and relates to a link combination type electronic device bracket. Background Art

[0002] In the market, more and more car owners use in-vehicle electronic product brackets. Most of the brackets in the market use a housing, which is generally divided into a front housing and a rear housing to restrain or support a left clamping arm or / and a right clamping arm. The housing requires manufacturing costs and assembly costs. There are few electronic device brackets directly composed of links in the market. The closest technology is an electronic device bracket with the application number 202123126817.8, which uses a combination of multiple links and multiple elastic reset components. There is no link synchronization structure, resulting in free swinging of the links and the bottom support member, causing instability. The multiple elastic reset components also increase the assembly difficulty. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model aims to provide a link combination type electronic device bracket. The first link is hinged to the base external connection member through a first rotating shaft. A first tooth portion that can rotate around the first rotating shaft is provided on the first link. A second rotating shaft is provided between the second link and the base external connection member. The second link is hinged to the base external connection member through the second rotating shaft. A second tooth portion that can rotate around the second rotating shaft is provided on the second link. The first tooth portion meshes with the second tooth portion. A third tooth portion is provided on the third link, and a fourth tooth portion is provided on the fourth link. The third tooth portion and the fourth tooth portion are engaged with each other for synchronization technology. The first link and the second link are also connected to the base external connection member through a rotating shaft bolt passing through a through hole on the base external connection member for rotation. It realizes the synchronous rotation of the first link and the second link and the synchronous rotation of the third link and the fourth link. When an electronic device is placed on the bottom support member, the third link and the fourth link both rotate downward to pull the first link and the second link to swing, and their clamping portions move towards the electronic device for clamping. When there is no electronic device on the bottom support member, all the links return to the non-clamping state under the action of the return elastic member. This technology also realizes the combination of various links into a flat support surface for the support surface of the electronic device through reasonable overlap and movable connection of the links. By reasonably setting each stop surface of the links and using synchronous gears, the links rely on each other and have synchronization when the links act, achieving good performance and a neat and beautiful appearance.
