The invention is a suitcase having a frame integrally formed from a composite material and a fabrication method therefor. The method comprises the following steps: A) preparing a thermoplastic sheet into an outer housing; B) placing a housing body of the outer housing in an inner concave mold region of a heating mold, placing a housing edge of the housing in a frame mold region of the heating mold, and enabling an outer surface of the housing to correspond to an inner wall surface of the heating mold; C) placing an outer surface of a thermosetting carbon fiber plastic layer on an inner surface of the housing; D) providing a filling layer on an inner surface of the thermosetting carbon fiber plastic layer and located in the frame mold region; and E) using a balloon to expand against the thermosetting carbon fiber plastic layer and the filling layer, and heating same by means of the heating mold, such that the housing, the thermosetting carbon fiber plastic layer and the filling layer are bonded to one another.

A suitcase (1) comprises a housing (2), a plurality of wheels (6) and a grip member (4), wherein the housing (2) has a base layer (22) and a protective layer (24). The base layer (22) is made of a thermoset polymer material, and the protective layer (24) is made of a thermoset polymer material and covers at least one side of the base layer (22). Thereby, the housing (2) of the suitcase (1) has impact and damage resistance.
A seat structure with function of suspension includes a seat tube and a cushion body installed on the seat tube. The seat tube and cushion body are made of carbon-fiber materials. The cushion body includes an integrated seat and a bracket. The bracket is installed on the seat tube. The bracket is an arc piece. The front end of the bracket and the front end of the seat are integrally molded and connected to form a first angle. The rear end of the bracket and the rear end of the seat are integrally molded and connected to form a second angle. The first angle and the second angle are less than 90°, thereby enabling the seat being good elasticity relative to the bracket, which can effectively reduce the vibration transferred from the seat tube. The seat structure has larger elasticity coefficient and better effect of damping.
A seat structure with function of suspension, comprises a seat tube (10) and a cushion body (20) installed on the seat tube (10), the seat tube (10) and cushion body (20) are produced of carbon-fiber materials, the cushion body (20) comprises an integrated seat (21) and a bracket (22), the bracket is installed on the seat tube, the bracket is an arc piece, the front-end of the bracket and the front-end of the seat are integrally molded and connected to form the first angle R1, the rear-end of the bracket and the rear-end of the seat are integrally molded and connected to form the second angle R2, the first angle R1 and the second angle R2 are less than 90°, thereby causing the seat being good elasticity relative to the bracket, which can effectively reduce the vibration transferred from the seat tube, the seat structure has larger elasticity coefficient, better effect of damping, replacing the traditional bracket and the seat type separately connection the way need to install shock absorbers, the seat structure requires fewer parts, more simple structure and assembly, is advantageous in enhancing the efficiency of production assembly.
