[0015] The present invention will be further described below with reference to the accompanying drawings: As shown in the attached figure, a mold for manufacturing a carbon fiber scooter carrier body includes an upper mold plate 7 and a lower mold plate 8. The lower mold plate 8 is characterized by having a vehicle carrier body upper end face forming groove 9 on its upper end face, a battery mounting groove forming protrusion 10 in the middle of the vehicle carrier body upper end face forming groove, and pulley mounting groove lower forming protrusions 11 on both sides of the battery mounting groove forming protrusion 10 on the lower mold plate 8. The upper mold plate 7 is characterized by having a vehicle carrier body lower end face forming groove 12 on its lower end face, and pulley mounting groove upper forming protrusions 13 on both sides of the upper mold plate 7 inside the vehicle carrier body lower end face forming groove 12. The vehicle carrier body upper end face forming groove 9 and vehicle carrier body lower end face forming groove 12 on the upper mold plate 7 and the lower mold plate 8 form a vehicle carrier body forming cavity after the mold is closed.

[0016] Furthermore, the lower template 8 is fixed with a protruding guide post 14, and the upper template 7 is provided with a guide hole 15 that cooperates with the guide post 14. The upper template 7 and the lower template 8 are guided and molded together by the cooperation and insertion of the guide post 14 and the guide hole 15.

[0017] Furthermore, the lower template 8 is provided with positioning protrusions 16 at the four corners, and the upper template is provided with positioning grooves 17 at the four corners that cooperate with the positioning protrusions 16. After the upper template 7 and the lower template 8 are closed, the upper template 7 and the lower template 8 are aligned and closed by the cooperation of the positioning protrusions 16 and the positioning grooves 17.

[0018] The aforementioned mold for manufacturing a carbon fiber scooter support body produces a support body comprising a carbon fiber outer sheath 1 and a foamed core layer 2. The carbon fiber outer sheath 1 includes a lower outer sheath 3 and an upper outer sheath 4. The outer layer of the foamed core layer 2 is shaped like the scooter support body. The front and rear parts of the foamed core layer 2 are respectively provided with wheel mounting grooves 5, and the middle part of the foamed core layer 2 is provided with a battery mounting groove 6. The lower side of the foamed core layer 2 is wrapped with the lower outer sheath 3, and the upper side of the foamed core layer 2 is wrapped with the upper outer sheath 4. The edges of the upper outer sheath 4 and the lower outer sheath 3 are integrally wrapped and connected. The upper outer sheath 4 and the lower outer sheath 3 fit and wrap with the shape of the foamed core layer 2 to form the carbon fiber scooter support body.

[0019] The manufacturing method of the carbon fiber scooter carrier body of this utility model is as follows: First, a foamed core layer 2 is made. Battery mounting slots 6 and wheel mounting slots 5 are formed on the foamed core layer 2. The shape of the foamed core layer 2 is the shape of the scooter carrier body. After its manufacture, carbon fiber prepreg is laid in the forming groove 9 on the upper end face of the vehicle carrier body of the lower template 8 to form the lower outer protective layer 3 of the vehicle carrier body. Then, the foamed core layer 2 is fastened onto the laid lower carbon fiber prepreg, and the battery mounting slots 6 of the foamed core layer 2 are inserted into the battery mounting grooves of the lower template 8 to form the scooter carrier body. On the protrusion 10, the pulley mounting groove 5 of the foam core layer 2 is inserted into the protrusion position below the battery mounting groove 6 of the lower template 8. Then, the carbon fiber prepreg fabric of the upper outer sheath 4 is laid on top of the foam core layer 2 that is fastened to the lower template 8, and is integrally wrapped with the edge of the carbon fiber prepreg fabric of the lower outer sheath 3 on the outside of the foam core layer 2. After wrapping, the upper template 7 moves down, and the protrusion 13 formed on the pulley mounting groove inside the lower end face forming groove 12 of the upper template 7 is inserted into the pulley mounting groove 5 of the foam core layer 2. After the forming protrusion 13 aligns with the forming protrusion 11 under the pulley mounting groove, a forming gap is formed for the pulley fixing part. The plate-like structure formed after the pulley fixing part forming gap can install the pulley. After the upper mold 7 and lower mold 8 are closed, heating causes the carbon fiber prepreg fabric of the upper outer protective layer 4 and the lower outer protective layer 3 to be integrally formed and wrapped around the outside of the foam core layer 2. After demolding, a carbon fiber scooter carrying body is formed. Later, the pulley is installed in the pulley mounting groove 5 and the battery is installed in the battery mounting groove. The battery wire is drilled from the side of the battery mounting groove 6 and led out to connect with the pulley in the pulley mounting groove 5. Then, the upper end of the carbon fiber scooter body is attached by attaching the carbon fiber panel in the shape of a scooter. The carbon fiber scooter carrying body formed above is lighter than that of aluminum alloy, and has high overall strength and good support performance. It is formed by the specific upper mold 7 and lower mold 8, which has low production cost and high production efficiency. Due to the above structure, this utility model has the advantages of simple structure, light weight, good support performance, low production cost and high production efficiency.
