TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile seat, especially relates to a split assembly type automobile seat. BACKGROUND

[0002] In the process of continuous development of the automobile industry, the automobile seat as the internal part of the vehicle is very important, and its performance and design directly affect the passenger's riding experience and the utilization rate of the vehicle space. With the increasing demand of consumers for the convenience of using the car, the flexibility of space and the convenience of maintenance and maintenance, the traditional automobile seat design has been difficult to meet the diversified needs of the modern automobile market in many aspects, and some problems need to be solved.

[0003] The traditional automobile seat usually adopts an integrated design of a whole or a close connection, and the backrest assembly, the support assembly and the cushion assembly are connected into a relatively fixed whole structure. However, this structure brings many inconveniences in actual use and maintenance. In terms of maintenance, since the parts are closely connected, when any one part of the backrest assembly, the support assembly or the cushion assembly of the seat is damaged, the whole seat often needs to be disassembled. This not only increases the complexity and difficulty of the repair work, but also leads to the extension of the repair time and the substantial increase of the repair cost. In terms of space utilization and seat storage, the design of the traditional automobile seat also has obvious defects. Since the support assembly and the cushion assembly are connected with each other, the cushion assembly is easily interfered by the support assembly when it is turned up and folded. This interference makes the cushion assembly unable to fully turn up in place, resulting in that the seat still occupies a large space in the car in the storage state, cannot effectively release the space in the car and limits the flexible use of the space in the car.

[0005] In order to achieve the above object, the utility model provides a split assembly type automobile seat, including backrest assembly and cushion assembly, the bottom front end of cushion assembly is supported on the car body floor through the footrest, still include support assembly, support assembly is arranged between the bottom of backrest assembly and the rear end of cushion assembly, the rear end of cushion assembly is fixed on the car body through cushion support on both sides respectively, wherein the cushion support and the cushion support are rotationally connected, the cushion support and the car body are fixedly connected, two cushion supports are also equipped with the rear opening lock hook groove, the back lower end of support assembly is equipped with two U type lock bolts left and right interval, two U type lock bolts are inserted into two lock hook grooves one by one, the back upper end of support assembly is equipped with steel wire support, steel wire support is fixedly connected with the car body, the lower end of backrest assembly is fixed on the car body through backrest support on both sides respectively, wherein the backrest assembly and the backrest support are rotationally connected, and the backrest support and the car body are fixedly connected.

[0006] In the above scheme: the cushion support is welded with L-shaped sheet metal support, and the lock hook groove is opened on the vertical section of the sheet metal support. The L-shaped sheet metal support provides a clear installation position for the lock hook groove. In the assembly process, the worker can more easily align and insert the U-shaped lock bolt of the support assembly into the lock hook groove.

[0007] In the above scheme: a circle of limiting steps is arranged on the horizontal section of the two U-shaped lock bolts, when the horizontal section of the U-shaped lock bolt is inserted into the lock hook groove, the limiting steps are just abutted on the side wall of the corresponding lock hook groove from inside to outside, and the limiting steps on both sides cooperate to limit the left and right shaking of the support assembly.

[0008] In the above scheme: two steel wire supports are arranged on the back upper end of the support assembly left and right interval, and a foot plate is welded on the two steel wire supports, and the foot plate is fixedly connected with the car body through a screw. The structure is simple and convenient to process.

[0009] In the above scheme: the backrest support and the cushion support are fixed on the car body through a screw, and the structure is simple and convenient to assemble.

[0010] In the above scheme: the bottom end of the footrest is provided with a rubber pad, which plays a role of shock absorption and buffering.

[0011] In the above scheme: the seat cushion support is welded with an L-shaped fixing support, the footrest top end is hinged to the bottom front end of the seat cushion assembly, the footrest left and right ends are respectively connected to the corresponding side fixing support through a transmission rod, the transmission rod is hinged to the footrest and the fixing support, and the hinge point of the transmission rod and the fixing support is located below the hinge point of the seat cushion assembly and the seat cushion support, when the seat cushion assembly is folded upwards around the seat cushion support, the transmission rod is limited in length and can pull the footrest to fold backwards on the back of the seat cushion assembly. This linkage design makes the footrest not occupy extra space in the car during the folding of the seat, especially for the car with limited space, which can effectively avoid the interference between the footrest and other parts in the car, provide more space for passengers to get on and off the car and place objects in the car, and link the folding actions of the footrest and the seat cushion assembly, realize the integrated storage of the related parts of the seat, and make the storage process of the seat more simple and efficient.

[0012] The beneficial effects of the utility model are:

[0013] 1. Through the split type design, the seat is divided into a seat cushion assembly, a support assembly and a backrest assembly, each part can be independently assembled on the vehicle body, which simplifies the assembly process, improves the assembly efficiency and reduces the assembly difficulty. 2. The split type structure enables each part of the seat to be separately disassembled and installed, facilitating subsequent maintenance and repair work and reducing maintenance and time costs. 3. The rear end of the seat cushion assembly is rotationally connected with the seat cushion support, and the U-shaped lock bolt of the support assembly cooperates with the lock hook groove on the seat cushion support, which can effectively avoid interference when the seat cushion assembly is folded upwards, ensuring the flexibility and comfort of the seat.
