The rear sidewall of the pad corresponds to the opening side of the U-shaped frame, the front sidewall corresponds to the front tube of the U-shaped frame, and the left and right sidewalls correspond to the side tubes of the U-shaped frame. The side tubes extend out of the pad towards the opening side of the U-shaped frame to form a socket tube, which is assembled with the backrest frame of the wheelchair. At the same time, a connecting ear is integrally provided at the bottom of the front tube end of the side tube, which is assembled with the support frame of the wheelchair.

[0006] Furthermore, a plurality of waist-shaped weight-reducing holes are arranged parallel to each other on the pad, and the length direction of the waist-shaped weight-reducing holes is consistent with the length direction of the side tube of the U-shaped frame.

[0007] Furthermore, the waist-shaped weight-reducing hole includes two side holes and several central holes, with the two side holes respectively located near the side tubes on both sides; the central holes are located between the two side holes.

[0008] Furthermore, the length of the central hole is longer than the length of the side hole, and the width of the central hole is smaller than the width of the side hole.

[0009] Furthermore, the central hole comprises three holes.

[0010] Furthermore, a pull hole is provided on the pad, the pull hole is an oblong hole, located near the front tube, and the length direction of the oblong hole is consistent with the length direction of the front tube.

[0011] Furthermore, the seat plate is made of carbon fiber.

[0012] A molding die for an integrated seat plate as described above includes an upper mold plate and a lower mold plate, wherein one side of the upper mold plate and the lower mold plate are hinged together; for the molding of the U-shaped frame and the pad plate of the integrated seat plate, the upper mold plate and the lower mold plate are provided with U-shaped frame channels and plate channels; and the upper mold plate and the lower mold plate are provided with a plurality of injection flow channels corresponding to the U-shaped frame channels and plate channels.

[0013] Furthermore, a clamping block is provided on the lower template, the clamping block is located near the hinge side, and the clamping block is located on the U-shaped frame channel for forming the connecting ear of the integrated seat plate.

[0014] Furthermore, a handle groove is provided on the side of the upper template and the lower template away from the hinge side.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The U-shaped frame and seat plate of this application feature an integrated design, which not only reduces the difficulty of processing and installation and decreases the number of fixed parts, but also ensures the stability of the wheelchair. In addition, the seat plate is made of carbon fiber, ensuring its lightweight nature. By incorporating weight-reducing grooves, the elasticity of the seat plate is increased, enabling it to remain undeformed even when bearing a load of over 140KG. Attached Figure Description
