As preferable:
the two ends of the beam body extend downwards towards the side rear direction respectively and then extend along the length direction of the beam body to form the first butt joint table top;
The two ends of the upturning edge extend along the upper edge of the corresponding first butt joint table top to form an upturning extending edge, and the free edge of the upturning extending edge is upturned to form the second butt joint table top;
the two ends of the downward turning edge extend along the lower edge of the corresponding first butt joint table top to form a downward turning extending edge, and the free edge of the downward turning extending edge is turned downwards to form the third butt joint table top.
When the structure is adopted, the beam body is mainly used for supporting the shoulder of the passenger, the shoulder supporting part is formed into an open structure relatively to the first butt joint table tops at the two ends of the beam body, the structure can adapt to passengers of different sizes, a convex angle is formed between the part, extending to the rear lower side, of the beam body and the beam body, and when the beam body is subjected to lateral shearing force, the convex angle can play a certain role in shearing resistance, so that the shearing resistance of the beam body is improved.
A first reinforcing plate is connected between the two second butt joint table tops and fixedly connected with the upper turnover edges. The structure can effectively strengthen the strength of the second butt joint table top.
A second reinforcing plate is connected between the two third butt joint table tops and fixedly connected with the lower turnover edges. The strength of the third butt joint table top can be effectively improved by adopting the structure.
The upper turnover edge is provided with a headrest tube inserting hole, the lower turnover edge is provided with a headrest tube abutting groove, and the hole core line of the headrest tube inserting hole coincides with the groove core line of the headrest tube abutting groove. When the structure is adopted to conveniently install the headrest tube, the lower end of the headrest tube is inserted into the headrest tube inserting hole and abutted against the bottom of the headrest tube abutting groove, and the headrest tube is more convenient to fix.
And the beam body is provided with a welding hole, and the hole core line of the welding hole is perpendicularly crossed with the hole core line of the headrest tube inserting hole. After the headrest tube is inserted into the headrest tube inserting hole by adopting the structure, the headrest tube and the beam body can be welded together through the welding hole from the side surface of the headrest tube.
The upper edge of the transition plate body is folded inwards to form a butt joint limiting plate. The butt joint limiting plate with the structure plays a role in limiting the upper position of the upper beam of the installed backrest, and prevents the backrest from falling off.
The rearward orthographic projection of the first docking area is located between the rearward orthographic projections of the second docking area and the third docking area. By adopting the scheme, a concave structure is formed among the three butt joint areas, and the three butt joint table tops matched with the concave structure are of convex structures, so that the butt joint of the three butt joint table tops is firmer.
The beneficial effects are that: the upper beam of the backrest is in butt joint with the transition plates hinged to the side plates of the backrest through the three butt joint table tops to form a mortise-like connection structure, the upper beam of the backrest is very convenient to mount and dismount, and in addition, the position of the main supporting shoulder on the upper beam of the backrest is more forward, so that the backrest can adapt to passengers with different sizes, and meanwhile, the shearing resistance of the whole backrest framework is effectively improved.
