[0002] like Figure 2 As shown, the existing seat back panel and back panel lining are connected and positioned with the seat frame through upper and lower spaced steel wire connecting rods. Once the positions of the two steel wire connecting rods deviate, it will directly affect the position matching between the seat back panel and the back panel lining, thereby affecting the assembly of the two, resulting in installation failure and delaying the assembly period. Utility Model Content

[0003] The utility model aims to provide a seat backrest back panel assembly reinforced connection component, which has a stable position and can be accurately installed, and solves the problem that the seat backrest back panel and the back panel lining are connected and positioned with the seat frame respectively through upper and lower spaced steel wire connecting rods. Once the positions of the two steel wire connecting rods deviate, it will directly affect the position coordination problem between the seat backrest back panel and the back panel lining.

[0004] To this end, the technical solution adopted by the utility model is: a seat backrest backboard assembly reinforcement connection component, including an upper connecting rod, a lower connecting rod hooked on the inner side of the backrest backboard and a reinforcement connecting plate fixedly connected to the backboard lining. The upper connecting rod and the lower connecting rod extend upward and backward along the backward tilting trend of the backrest backboard as a whole, and the left and right ends are welded and installed on the backrest frame. The upper and lower ends of the reinforcement connecting plate are respectively fixedly connected to the middle horizontal section of the upper connecting rod and the middle horizontal section of the lower connecting rod, so as to fix the position of the backrest backboard, the backboard lining and the backrest frame. The left and right sides of the backboard lining are fixedly connected to the backrest frame through a horizontal connecting piece. The inner side of the backrest backboard is provided with an open and obliquely upward card slot, and the left and right sides of the lower connecting rod are provided with horizontal sections hooking the card slot.

[0005] As a preferred embodiment of the above scheme, the reinforced connecting plate and the back plate lining are connected by gantry clips and screws, which are firmly fixed and easy to install.

[0006] Further preferably, the horizontal connecting member as a whole is a "C"-shaped groove structure with its opening facing forward, the upper and lower side panels of the horizontal connecting member are provided with arc-shaped notches that match the contour of the backrest frame, the vertical plates are provided with mounting holes at intervals on the left and right, and are equipped with screws that pass through the inner side panels of the back panel lining and are inserted into the mounting holes. The design is reasonable to ensure that the installation position of the back panel lining is stable and to strengthen the connection with the backrest frame.

[0007] Further preferably, the back panel lining is symmetrically provided with installation platforms corresponding to the horizontal connecting members and the reinforcing connecting plates on the left, middle and right sides, so that they can be installed with screws after being fitted together, and the installation is convenient and quick, and the design is reasonable.

[0008] Further preferably, the upper and lower ends of the reinforcing connecting plate are respectively welded to the middle horizontal section of the upper connecting rod and the middle horizontal section of the lower connecting rod, and the welding is firm.

[0009] Further preferably, the back panel lining member protrudes outwardly corresponding to the outer end of the horizontal connecting member to form a space for accommodating the horizontal connecting member, which effectively avoids positional interference between the two and is reasonably designed.

[0010] Beneficial effects of the utility model:

[0011] (1) Compared with the seat backrest and back panel lining parts connected and positioned with the seat frame through upper and lower spaced steel wire connecting rods, this solution adopts the middle horizontal section of the upper connecting rod and the middle horizontal section of the lower connecting rod to be fixedly connected through a reinforcing connecting plate, thereby directly connecting the backrest backrest, back panel lining parts and the backrest frame in relative position, strengthening the position connection, ensuring smooth assembly, accurate assembly position, ingenious design, and interlocking structure.

[0012] (2) The lower connecting rod is provided with horizontal sections on the left and right sides for convenient hooking into the slots. The hook connection is convenient for assembly and disassembly. The left and right sides of the back panel lining are also directly fixedly connected to the backrest frame through horizontal connecting pieces. The back panel lining is connected at three points, left, middle and right, to form a triangular stable installation, which is securely installed, has a stable structure and accurate positioning.

[0013] In summary, it has the advantages of precise assembly position, ingenious design, interlocking structure, reliable installation and stable structure. BRIEF DESCRIPTION OF THE DRAWINGS
