Car roof lifting mechanism and mounting structure of lifting type car roof

Abstract

The invention discloses an automobile ceiling lifting mechanism and a mounting structure of a lifting type roof, the upper end and the lower end of the ceiling lifting mechanism are rotatably mounted between an automobile ceiling and a roof side wall respectively, the ceiling lifting mechanism comprises two telescopic arms which are arranged in a front-back spaced mode, and each telescopic arm is composed of an upper rotating arm and a lower rotating arm; a through groove is formed in the same side of each lower rotating arm in the length direction of the lower rotating arm, and the lower end of each upper rotating arm is rotatably installed at the upper end of the corresponding lower rotating arm and can be clamped in the through groove of the corresponding lower rotating arm under the action of external force. An upper linkage piece and a lower linkage piece are arranged between the two telescopic arms, the upper linkage piece is located between the two upper rotating arms, and the left end and the right end of the upper linkage piece are rotationally connected with the upper rotating arms on the same side respectively; the lower linkage piece is located between the two lower rotating arms, and the left end and the right end are rotationally connected with the lower rotating arms on the same side. The driving mechanism is fixedly connected with the lower linkage piece and can pull the lower linkage piece to move front and back.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to an automobile ceiling lifting mechanism and an installation structure of a lifting roof. Background technique [0002] With the improvement of the quality of life, the number of users who go out to play and get close to nature is increasing, and the vehicle is also changing from the traditional transportation function to the multi-scenario variable multi-functional space. Based on this, the number of vehicles whose roof can be lifted is also increasing . For example, the Chinese patent application No. 2019204375090 discloses a roof lifting mechanism for a caravan, including a first electric push rod and a second electric push rod located on the upper part and a third electric push rod and a fourth electric push rod located on the lower part. The first hinged seat and the second hinged seat are symmetrically arranged on the left and right sides of the front part above the t...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned ceiling lifting mechanism realizes the hinged ceiling lifting by adopting the expansion and contraction of multiple electric push rods. Although this kind of lifting mechanism has a stable structure, its overall cost is high, and it is all realized by electric push rods. If one of the electric push rods If there is a failure, it will affect the lifting of the ceiling, which is inconvenient for maintenance

In addition, the overall height of the lifting mechanism is relatively large after being folded, so it needs to occupy a large storage space
