For example, as shown in fig. 1, the connection plate 3 is fixed to the rear side of the back plate 2 and the fixed tube 1 is located between the connection plate 3 and the back plate 2. Because light alloy spare such as aluminum alloy, magnesium alloy can not carry out effective connection through the welded mode with the carbon steel, and light alloy material's intensity and rigidity are low relatively under the same size, the connecting plate of steel material is provided with to be favorable to playing the effect of reinforcement promptly to improve the effect of backplate subassembly 100's intensity, and when backplate subassembly 100 was used on the seat, connecting plate 3 can also link to each other with other structures of seat for example the regulator of steel spare links to each other to the connection problem of backplate subassembly 100 with other structures of seat has been solved. Optionally, the connecting plate 3 is high-strength steel.
According to the backboard assembly 100 of the seat, the fixing pipe 1 is enabled to define the frame structure 10, the backboard 2 is laid on the fixing pipe 1, the connecting plate 3 is fixed on one side, adjacent to the fixing pipe 1, of the backboard 2, the fixing pipe 1 and the connecting plate 3 are made of light alloy pieces, and the backboard 2 and the fixing pipe 1 are made of steel pieces, so that the quality of the backboard assembly 100 is favorably reduced on the basis of ensuring the strength of the backboard assembly 100, when the backboard assembly 100 is used on the seat, the quality of the seat is favorably reduced, the energy consumption of the vehicle is reduced in the driving process of the vehicle, and meanwhile, the problem of connection between the backboard assembly 100 and other structures of the seat is solved.
