Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seats, and particularly relates to a vehicle seat that can be detachably used. Background Art

[0002] With the rapid development of the automotive industry, automobiles have become the most important part of the urban transportation system. In recent years, China's automotive industry has developed rapidly and will continue to develop steadily in the next period. As an important component of automobiles, vehicle seats still have huge development space in the future.

[0003] The structure of traditional vehicle seats has the following disadvantages and deficiencies, specifically manifested as follows: The connection structure between the seat and the vehicle body is mainly in the form of bolt fixation, which cannot achieve quick installation and disassembly; when people are traveling outside, sometimes they cannot find a place to rest and can only rest in the vehicle, and the vehicle seat cannot be removed and used as a separate chair, which affects the viewing of the scenery, etc.; for some vehicles that need to disassemble and install the seat to meet the interior space requirements, disassembling and installing the seat is very troublesome and not convenient. Existing vehicle seats have solved the above problems through a quick-release structure, but their support leg structure is complex, folding and storage are inconvenient, and moreover, due to the limitation of the design principle of the support leg structure of existing vehicle seats, its support height is relatively low, and the comfort is poor when it is removed and used as a separate chair. Summary of the Utility Model

[0004] Aiming at the problems existing in the above-mentioned prior art, the utility model aims to provide a vehicle seat that can be detachably used to solve the problems of complex support leg structure and limited support height of existing vehicle seats.

[0005] To achieve the above object, the utility model provides a vehicle seat that can be detachably used. The vehicle seat is fixed on the vehicle body floor through a quick-release structure. The vehicle seat includes a seat frame skeleton. Support wires are arranged on the top surface of the seat frame skeleton. A front support leg is hinged to the front end of the seat frame skeleton, and a rear support leg is hinged to the rear end of the seat frame skeleton. The front support leg and the rear support leg are both folded and stored under the seat frame skeleton. The front support leg supports on the rear support leg and is limited and fixed between the support wire and the rear support leg. An automatic locking and connecting component for supporting the rear support leg is arranged on the seat frame skeleton. When the automatic locking and connecting component is unlocked, both the rear support leg and the front support leg can be turned outwards and finally support in a spread-eagle shape under the seat frame skeleton.

[0006] In the above solution: The seat frame skeleton includes a square border. The support steel wires extend left and right and are arranged on the top surface of the square border. The front legs include two front support rods arranged symmetrically left and right. The two front support rods are respectively hinged at the two front corners of the square border. A first transverse connecting rod is connected between the two front support rods. The rear legs include two rear support rods arranged symmetrically left and right. The two rear support rods are respectively hinged at the two rear corners of the square border. A second transverse connecting rod is connected between the two rear support rods. The two front support rods are located between the two rear support rods, and the two front support rods are supported on the second transverse connecting rod. The structure is simple and the design is ingenious.

[0007] In the above solution: The two front support rods and the two rear support rods are both hinged to the square border through channel-shaped sheet metals. The structure is simple and the assembly is convenient. The size of the channel-shaped sheet metal connected to the front support rod is larger than the size of the channel-shaped sheet metal connected to the rear support rod.

[0008] In the above solution: The two ends of the second transverse connecting rod are designed in a sunken manner to form receiving grooves. The two front support rods are respectively looped in the receiving grooves on both sides, so as to be supported on the second transverse connecting rod. The structure is simple and the design is ingenious. The sunken design of the second transverse connecting rod is beneficial to improving the storage effect of the two legs.

[0009] In the above solution: The quick-release structure includes a floor lock arranged between the front end of the bottom of the seat frame skeleton and the vehicle body floor and two opening jackets arranged on both sides of the rear end of the seat frame skeleton. The floor lock is equipped with an unlocking handle for unlocking. The unlocking handle is integrally arranged in the seat cushion foam of the vehicle seat and is located at the front end of the seat cushion foam. The openings of the opening jackets face backward. Clamping bolts are respectively fixed on the vehicle body floor corresponding to the two opening jackets. The opening jackets are clamped on the corresponding clamping bolts. The lock body of the floor lock cooperates with the lock bolt to realize the limit fixation of the seat frame skeleton. When the unlocking handle pulls the floor lock to unlock, the seat frame skeleton can be turned upward around the rear end by a certain angle, so that the lock body of the floor lock is far away from the lock bolt, so that the opening jackets can be disengaged from the clamping bolts, thereby realizing the disassembly of the vehicle seat.

[0010] In the above solution: A handle is provided in the middle of the rear end of the seat frame skeleton, which is convenient for lifting and moving the disassembled vehicle seat.

[0011] In the above scheme: the automatic locking assembly includes a U-shaped sleeve with an opening downward and a hollow cylinder with an open end and a closed end. The top of the U-shaped sleeve is welded and fixed to the supporting steel wire, and a circular hole is provided on one side end of the U-shaped sleeve. The open end of the hollow cylinder is inserted into the circular hole from the outside to the inside and is fixed to the U-shaped sleeve by a welding nut. A locking ball is provided in the opening of the hollow cylinder, and a return spring is provided between the locking ball and the interior of the hollow cylinder. Half of the locking ball is exposed from the hollow cylinder and is sealed between the two side walls of the U-shaped sleeve, thereby locking the second transverse connecting rod in the U-shaped sleeve. Pulling down the second transverse connecting rod can completely squeeze the locking ball into the inner cavity of the hollow cylinder through the second transverse connecting rod, thereby realizing the unlocking of the automatic locking assembly, so that the rear support legs can be opened outward. Conversely, pulling up on the second transverse link can also completely squeeze the locking ball into the inner cavity of the hollow cylinder through the second transverse link, thereby pulling the second transverse link into the U-shaped sleeve and locking it, thereby achieving the storage and locking of the rear support leg. When the locking ball is not under force, the return spring can drive the locking ball to return to its original position.

[0012] In the above solution, the square frame is also equipped with longitudinal steel wires extending forward and backward. The top of the U-shaped jacket is located at the intersection of a support wire and the longitudinal steel wire and is welded to both. This means that the longitudinal steel wires extending forward and backward and the left and right support wires jointly support the U-shaped jacket, thereby supporting the front legs locked in the U-shaped jacket. These two steel wires further ensure support strength. Both the support wire and the longitudinal steel wire are built-in seat cushion wires of the seat frame and do not require additional installation.

[0013] The beneficial effects of the present invention are as follows: 1. By limiting and fixing the front legs between the support wire and the rear legs, the shaking of the front legs and the generation of abnormal noises are effectively avoided, and the support wire can be the seat cushion wire that comes with the seat, and no additional layout is required; the rear legs are supported on the automatic locking assembly, that is, the front legs and the rear legs are locked together by a single automatic locking assembly. When the automatic locking assembly is unlocked, the rear legs and the front legs can both flip outward, thereby supporting the bottom of the seat frame. The overall structure is simple and the design is ingenious. 2. The front legs are supported on the rear legs, which means that the front legs hinged to the front end of the seat frame and the rear legs hinged to the rear end of the seat frame have an overlap, which further illustrates that the front legs and the rear legs are relatively long and have a high support height.

The openings of the open jackets 10 face backward, and jacket lock bolts 12 are fixedly provided on the vehicle body floor corresponding to the two open jackets respectively. The open jackets 10 are clamped on the corresponding jacket lock bolts 12.

[0027] The lock body of the floor lock 9 cooperates with the lock bolt to achieve the limit fixation of the seat frame skeleton A. When the unlocking handle 11 pulls the floor lock 9 to unlock, the seat frame skeleton A can be turned upward around the rear end by a certain angle, so that the lock body of the floor lock 9 is far away from the lock bolt, so that the open jacket 10 can be disengaged from the jacket lock bolt 12, thus realizing the disassembly of the vehicle seat.

[0028] Preferably, a handle is provided in the middle of the rear end of the seat frame skeleton A to facilitate the manual movement of the disassembled vehicle seat.

[0029] Preferably, the automatic locking assembly D includes a U-shaped jacket 13 with an opening facing downward and a hollow cylinder 14 with one end open and one end closed.

The open end of the hollow cylinder 14 is inserted into the round hole from the outside to the inside and is fixed to the U-shaped jacket 13 through a welding nut 15. A lock ball 16 is provided inside the opening of the hollow cylinder 14. A return spring 18 is provided between the lock ball 16 and the inside of the hollow cylinder 14. Half of the lock ball 16 protrudes from the hollow cylinder 14 and is blocked between the two side walls of the U-shaped jacket 13, thus locking the second transverse link 6 inside the U-shaped jacket 13.

[0030] Pulling down the second transverse link 6 can completely squeeze the lock ball 16 into the inner cavity of the hollow cylinder 14 through the second transverse link 6, thus realizing the unlocking of the automatic locking assembly D and enabling the rear leg C to open outward. On the contrary, pulling up the second transverse link 6 can also completely squeeze the lock ball 16 into the inner cavity of the hollow cylinder 14 through the second transverse link 6, thus pulling the second transverse link 6 into the U-shaped jacket 13 for locking, and further realizing the storage and locking of the rear leg C. When the lock ball 16 is not stressed, the return spring 18 can drive the lock ball 16 to reset.

[0031] Preferably, the square frame 2 is also equipped with longitudinal steel wires 17 extending forward and backward. The top of the U-shaped jacket 13 is located at the intersection of the support wire 1 and the longitudinal steel wire 17 and is welded to both. This means that the longitudinal steel wires 17 and the left and right support wires 1 jointly support the U-shaped jacket 13, thereby supporting the front legs B locked within the U-shaped jacket 13. These two steel wires further enhance support strength. Both the support wire 1 and the longitudinal steel wire 17 are built-in cushion wires of the seat frame A and do not require additional installation.
