Vehicle door limiter for small automobile

Abstract

The invention relates to a limiter, and in particularly relates to a vehicle door limiter for a small automobile, and belongs to the technical field of automobile door limiting devices. The vehicle door limiter for the small automobile comprises a limiting arm; a limiting box is installed on the limiting arm; the left end and the right end of the limiting arm are provided with a limiter support and a stop block correspondingly; the limiting arm is composed of a limiting arm pull rod and a wrapping layer wrapped the outer surface of the limiting arm pull rod, which is characterized in that twopressing rollers are arranged in the limiting box; the limiting arm is arranged between the two pressing rollers; shafts are arranged at the two ends of the pressing rollers correspondingly; the tailends of the shafts are a dovetail; two Z-axis guide rails are symmetrically arranged on the inner side wall of the limiting box; dovetail grooves are formed in the Z-axis guide rails, and the dovetails are arranged in the dovetail grooves; and the two pressing rollers are correspondingly connected with a top plate and a bottom plate of the limiting box through springs. According to the vehicle door limiter for the small automobile, two Z-axis guide rails are symmetrically arranged on the inner side wall of the limiting box, the two ends of the pressing rollers are arranged on the Z-axis guiderails, so that the movement consistency of the pressing rollers is ensured.

Description

technical field [0001] The invention relates to a limiter, in particular to a door limiter for small automobiles, and belongs to the technical field of automobile door limiters. Background technique [0002] Such as figure 1 As shown, the car stopper is an auxiliary part that connects the car door with the car body. Its main function is to limit the opening angle of the car door, and its use frequency is very high. Existing car door limiter comprises limiter arm 1, limit box 2 that is installed on the limiter arm, limiter support 3 and block 4. The limiter bracket 3 and the block 4 are installed on the left and right ends of the limiter arm 1 respectively. The limit arm 1 is composed of a limit arm pull rod 5 and a cladding 6 wrapped on the outer surface of the limit arm pull rod. The limit box includes an elastic body and a stick at the elastic end. Though the motion locus of existing stick is to move up and down, the motion locus is random, irregular. Therefore, ther...
