Sliding stop structure

Abstract

The invention discloses a sliding stop structure. The sliding stop structure comprises a sliding plate and a fixed skeleton which realize sliding fit through a sliding mechanism, and further comprisesa stopping mechanism and a sliding damping mechanism. The stopping mechanism comprises a spring damping base and a stop sliding groove which are correspondingly fixed to the sliding plate and the fixed skeleton, and buffer limiting parts are disposed at both ends of the stop sliding groove. The spring damping base comprises an elastic sliding member and a limiting member, and the elastic member and the stop sliding groove can be in sliding fit under the action of sliding force and can be kept relatively stationary. The limiting member and the buffer limiting parts can realize the limiting fitwith the uniform change of the sliding force. The sliding damping mechanism comprises a moving member fixed to the sliding plate and a fixed member fixed to the fixed skeleton, and the moving membermeshes with the fixed member. The sliding stop structure can realize the stop of an armrest at an arbitrary position, and the sliding force is stable; and the damping feeling in the sliding and stopping process is enhanced by the provision of the sliding damping mechanism and the matching of the limiting member and the buffer limiting parts, so that the sense of manipulation is improved.

Description

technical field [0001] The present invention relates to a slip stop structure, in particular to a slip stop structure. Background technique [0002] The armrest is a commonly used device on the sub-dashboard of a car. It is usually located in the middle and rear of the sub-dashboard to facilitate the driver and passengers to rest their elbows. Due to the difference in human body size, the driver will adjust the front and rear positions of the seat according to the driving convenience. Therefore, the armrest needs to design a set of motion and stop mechanism to realize the front and rear sliding process to meet the needs of different elbow comfort zones. [0003] Chinese patent CN105522945B discloses a slidable armrest of a car hollow platform. In this structure, the plastic boss rubs against the sliding plate, and the metal reed is arranged behind the plastic boss. During the sliding process, the plastic boss rubs against the slide rail to stop When in position, the plasti...

Problems solved by technology

However, since the extrusion force provided by the metal reed is gradually attenuated after long-term compression and deformation, the sliding force gradually decreases, and it cannot effectively provide stop resistance at any position; at the same time, in the sliding process, only relying on the metal The friction between the reed and the chute provides a sense of sliding damping. At the start and end positions of sliding, the sliding resistance needs to gradually increase until it stops completely. This structure has a poor sense of stopping

On the other hand, the structure of the whole set of slide rails of the handrail is relatively complicated, and the Z-direction layout requires a large space
