Description

Automobile seat

Technical Field

The invention relates to a vehicle seat, in particular to a seat with position shifting and rotation on a vehicle.

Background

The seat of the traditional automobile can only be adjusted in the vertical direction and the front-back direction. In order to meet the requirements of adjustment of the seating direction and the seat of a driver and a passenger, a patent document named as "vehicle rotating and sliding type seat" (CN1938177A) discloses a related technical scheme, which comprises a rotating disc 1 and a sliding rail 2, wherein an upper rail 2a of the sliding rail 2 is provided with a base platform 1a, and the plate surface of the base platform 1a is provided with a lower platform 1b on the fixed side; the upper platform 1C on the east side is mounted on the lower side of the seat cushion C. The above scheme has the following problems: firstly, the rotating mechanism is arranged between the sliding rail 2 fixed on the vehicle bottom plate and the seat cushion C, and the connecting structure between the sliding rail 2 and the rotating mechanism and the connecting structure between the seat cushion C and the rotating mechanism are designed again, so that the complexity of the structure is obviously increased; secondly, the space height of the seat is increased, which brings new problems to the vehicle space; in the three rotating mechanisms, a platform support 1d in a rotary table 1 is riveted on an upper platform 1c, a lower platform 1b is fixed on a base platform 1a through bolts, and balls 1e and 1f are arranged at the positions of the upper platform 1c, the platform support 1d, the lower platform 1b and the platform support 1d, which are annular, and the cross sections of which are arc-shaped groove regions, so that the rotating structure of the seat is realized.

In addition, there are various seat rotation structure schemes, such as the name "a rotatable car seat" (CN 113733999A), in which the rotation component is the rotation shaft 2, and the middle part of the top of the bottom plate 1 is fixedly connected with the bottom of the rotation shaft 2, the top of the rotation shaft 2 is fixedly connected with the middle part of the bottom of the fixing plate 3, and the base 7 is connected on the fixing plate 3, so that the seat can rotate around the rotation shaft 2, when the vehicle bumps or stops suddenly, accelerates suddenly, and even collides, the seat shakes to apply a huge bending moment to the rotation shaft 2, and when the vehicle is seriously bent to break the rotation shaft 2, there is a serious safety hazard, and the scheme does not relate to the sliding mechanism of the seat. In the scheme of rotating the seat, the rotating mechanism rotating by the rotating shaft arranged in the middle is very representative.

For the rotary seat, the prior art usually adopts a manual operation scheme to restrain or lock the rotary position, such as "a latch device for seat bottom on sightseeing boat" (CN 214001983U), which uses the switch board 11 and the pull ring 12 to lock the seat indexing.

Disclosure of Invention

The invention aims to provide an automobile seat which can be adjusted in a rotating mode and a sliding mode, is stable in rotating operation and high in bending resistance, and occupies a small upper space and a small lower space.

In the technical scheme of the invention, the seat and the lower part thereof are connected with the sliding mechanism assembly to maintain the current situation that the existing seat and the lower part thereof are connected with the sliding mechanism assembly, the guide rail in the sliding mechanism assembly is connected on the rotating frame, and the rotating frame is matched with the circular ring type track to realize the rotation of the seat. According to the scheme provided by the invention, a lower sliding mechanism commonly adopted by the conventional vehicle seat does not need to be changed, only a rotating mechanism consisting of the rotating frame and the circular ring type track needs to be provided, and the sliding guide rail is arranged on the rotating frame, so that the time consumption and the material cost of design are saved, and the stability and the anti-overturning performance of the seat are ensured by the rotating matching scheme of the rotating frame and the circular ring type track; in addition, because the circular track is only arranged on the vehicle floor, the lifting height of the guide rail mounting surface of the seat is extremely limited compared with the height of the seat directly mounted on the floor, so the head space of a driver or a passenger after sitting is not influenced.
