Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0045] Referring to the drawings Figure 1 to the drawingsFigure 3 The utility model discloses an integrated roof box support type frame, include: type frame body 1, type frame body 1 is the shell structure that can cover the roof top surface of the automobile of being assembled according to the roof top surface shape of automobile of being assembled, type frame body 1 has the connecting hole 11 for being connected with automobile of being assembled, type frame body 1 has the openwork window 12, and the both sides edge of openwork window 12 is connected with support rod 2, and the both ends of support rod 2 are slidably connected with the both sides edge of openwork window 12 respectively.

[0046] In order to further optimize the above technical scheme, a plurality of metal band round hole gaskets are pre-buried at the connecting hole 11, which is used for connecting with the roof and plays a reinforcing role.

[0047] In order to further optimize the above technical scheme, the both sides edge of openwork window 12 is fixed with guide rail 13 through guide rail bolt, and the end of support rod 2 has sliding block 21 slidably connected with guide rail 13.

[0048] In order to further optimize the above technical scheme, the end of support rod 2 is fastened and connected with guide rail 13 through jacking screw.

[0049] The number of support rod 2 can be multiple, and in the embodiment, the number of support rod 2 is 3.

[0050] In the embodiment, according to the difference of vehicle type, the openwork window 12 is not necessarily regular rectangle, so the support rod 2 is telescopic rod, which can be adjusted according to the width of openwork window 12.

[0051] Referring to the accompanying drawings Figure 4 to the accompanying drawings Figure 6 Support rod 2 includes hollow main rod 22 and telescopic end rod 23 inserted at both ends of hollow main rod 22, a plurality of positioning holes 231 are formed on telescopic end rod 23, and hollow main rod 22 has locking hole 221 capable of being connected with positioning hole 231 through adjusting bolt.

[0052] In order to further optimize the above technical scheme, hollow main rod 22 has mounting connecting hole 222.

[0053] In order to further optimize the above technical scheme, type frame body 1 has lamp mounting groove 14 for mounting lamp. The lamp mounting groove 14 installs LED lamp combination body, and the combination body includes 12V LED lamp bead, PCB board, plastic structure box, wire harness and controller.

[0054] In order to further optimize the above technical scheme, type frame body 1 has groove 15 for pasting reflective sticker.

[0055] In order to further optimize the above technical scheme, type frame body 1 is carbon fiber composite material.

[0056] The preparation method of the mold body 1 of the carbon fiber composite material provided by the embodiment specifically comprises the following steps:

[0057] (1) Preparation: use a laser scanner to perform 3D scanning on the roof position to determine the installation position of the mold body 1, then use three-dimensional software to model the scanning position, design the shape required by the mold body 1, and then use the designed three-dimensional graphics to manufacture the upper mold and the lower mold (the mold material is P20 steel) required for producing the mold body 1.

[0058] (2) Prepare the heated upper mold, the heated lower mold, the foaming agent, the vacuum bag, and the carbon fiber prepreg cloth of the corresponding size.

[0059] (3) Carbon fiber prepreg cloth pasting step: paste a layer of carbon fiber prepreg cloth on the upper mold, and then perform pre-vacuuming. After pre-vacuuming is completed, paste carbon fiber prepreg cloth layer by layer, and perform pre-vacuuming once every several layers of carbon fiber prepreg cloth to ensure the strength. Install the positioning pin required to be embedded with a metal nut on the lower mold, and then install the metal nut with the pasted carbon fiber prepreg cloth on the positioning pin. Install the positioning pin required to be embedded with a metal round hole gasket on the lower mold, and then install the metal round hole gasket with the pasted carbon fiber prepreg cloth on the positioning pin. Paste a layer of carbon fiber prepreg cloth on the lower mold, and then perform pre-vacuuming. After pre-vacuuming is completed, paste carbon fiber prepreg cloth layer by layer, and perform pre-vacuuming once every several layers of carbon fiber prepreg cloth to ensure the strength.

[0060] (4) Foaming agent filling step: after the carbon fiber prepreg cloth pasting step is completed, fill the foaming agent on the carbon fiber layer corresponding to the inner cavity.

[0061] (5) Mold closing and autoclave curing forming step: cover the upper mold and the lower mold after the foaming agent is filled, and fasten them by using a screw rod. After the fastened mold assembly is placed in a vacuum bag and vacuumized, the mold assembly is in a vacuum state. Then, the vacuumized mold assembly is placed in an autoclave for heating, pressurizing and curing.

[0062] (6) Taking out step: the cured mold assembly is taken out from the autoclave, and after cooling, the mold is opened, the positioning pins for installing the metal nut and the metal gasket are disassembled, and then the mold body 1 is taken out.

[0063] (7) Polishing step: the excess residual material of the cured mold body 1 is polished, and then the product surface resin and other impurities are cleaned by using a sand blasting device.

[0064] (8) Polishing step: the polishing step is divided into three steps of water polishing, dry polishing and polishing, and the main purpose is to further process the carbon fiber lines on the surface of the mold body 1 to meet the design requirements.

[0065] (9) paint spraying step: finally, a clear paint is sprayed on the surface of the mold body 1 to make the surface more beautiful and more corrosion resistant. The mold body 1 sprayed with paint is placed in an oven to bake and dry to obtain a one-piece hollow carbon fiber mold body.

[0066] The steps of another method are substantially the same as those of the above method, except that step (4) is different: in step (4) of the other method, after the carbon fiber prepreg pasting step is completed, the special-shaped air pipe is laid on the carbon fiber layer corresponding to the inner cavity, the special-shaped air pipe can be blown to expand, and after expansion, it can apply the required pressure to the carbon fiber layer for curing, without the need for a foaming agent to fill. Therefore, no foaming agent needs to be prepared in step (2), and the special-shaped air pipe needs to be prepared instead. A plurality of blowing holes are designed on the left and right inner sides of the hollow window 12 in the mold body 1, to facilitate the installation of the special-shaped air pipe.

[0067] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other. For the device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method part.

[0068] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
