Abstract

The invention discloses a lower arm structure of a middle sliding door of an automobile. The lower arm structure comprises a lower arm body, a rotary connecting piece on the lower arm body, a roller on the rotary connecting piece, and a guide rail matched with the roller, wherein the cross section of the guide rail is inverted-T-shaped, and consists of a welded edge and a longitudinal ridge which is vertical to the welded edge; the circumferential surface of the roller is provided with a V-shaped groove matched with the longitudinal ridge in the peripheral direction; the roller can be driven to slide relative to the guide rail by the rotary connecting piece. The lower arm structure is simple and can solve the problems of clamping stagnation and abnormal noise of the middle sliding door due to excessive accumulation of ash and dust.

Description

technical field [0001] The invention relates to automobile body parts, in particular to a lower arm structure of a sliding door in an automobile. Background technique [0002] The lower arm structure of the middle sliding door of the automobile is an important part to drive the middle sliding door to slide in the prescribed trajectory and realize the opening and closing of the middle sliding door. Such as figure 1 As shown, the lower arm structure of the sliding door in the existing automobile comprises a lower arm body 1, a rotating connector 2 installed on the lower arm body, a lower arm bearing wheel 7 installed on the rotating connector for supporting sliding, and a lower arm bearing wheel 7 installed on the rotating connector. The lower arm guide wheel 8 used for guiding and sliding on the parts, the chute-type guide rail 9 welded on the vehicle body and matched with the lower arm guide wheel, the lower arm bearing wheel 7 is a bearing structure, and is in contact with...
