Opening and closing mechanism assembly for inner cover plate of glove compartment of vehicle

Abstract

The invention discloses an opening and closing mechanism assembly for an inner cover plate of a glove compartment of a vehicle, comprising a mounting base connected on the inner cover plate, wherein cassettes, chock blocks and a gear shaft for mounting a lock gear are arranged on the mounting base, two lock pull rods, namely a left lock pull rod and a right lock pull rod, are oppositely arranged at the upper and lower sides of the mounting base side by side, and the lock pull rods are movably mounted on the mounting base respectively through the cassettes and can move left and right along the mounting base; racks are respectively arranged on the lock pull rods, and the two lock pull rods are in meshing connection with the lock gear mounted on the gear shaft respectively through the racks; a spring is arranged on the mounting base and is respectively connected with the mounting base and the left lock pull rod; and the chock blocks are arranged on the positions opposite to the racks on the lock pull rods and used for limiting meshing clearances between the racks and the lock gear. By reasonably arranging assembly clearances among the parts, part structures are optimized, interference of the parts in the opening and closing mechanism is avoided in an assembly process, and the problem of unsmooth motion of the mechanism is effectively solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an opening and closing mechanism assembly of an inner cover plate of an auto glove box. Background technique [0002] In the inner cover of the glove box, the opening and closing function of the opening and closing mechanism is an important part that affects the use of the glove box. Therefore, high requirements are placed on the molding quality and assembly quality of the parts in the opening and closing mechanism. When selecting materials for the glove box opening and closing mechanism, in order to meet the friction resistance between the moving components in the glove box opening and closing mechanism and enhance the comfort performance of customers when opening the glove box, the opening and closing mechanism assembly usually adopts its own lubrication It is a permanent POM material, but the shrinkage rate of the POM material is large, and it is easy to cause shrinkage or ...
