[0027] Please see Figure 1 , Figure 1 This is a flowchart of a method for manufacturing the housing 103 according to the present invention, the method comprising: Step 01: Provide the preform, airbag, mold and curing oven.
[0028] The airbag is shaped like the inner cavity of the shell 103 and has an inflation port.
[0029] In some embodiments, the airbag includes a shell and a filler. The shell encloses the filler, which is shaped like the inner cavity of the shell 103, such that the airbag is shaped like the inner cavity 1031 of the shell 103. The filler is made of polystyrene foam, which shrinks when heated. During the manufacture of the filler, an engraving device is used to engrave the outer surface of the filler into the shape of the inner cavity 1031 of the shell 103.
[0030] It is understood that in some embodiments, the surface of the housing is provided with a release cloth, which is used to facilitate the separation of the housing 103.
[0031] Step 02: Apply the preform to the surface of the airbag.
[0032] The preform comprises an outer layer, a first reinforcing member, a second reinforcing member, a third reinforcing member, a fourth reinforcing member, and an inner layer. Both the outer and inner layers are made of aramid epoxy prepreg, which possesses excellent mechanical properties: a strength of 3.6 GPa, an elongation modulus of 131 GPa, and an elongation at break of 2.8%. It also exhibits excellent thermal properties, with a long-term service temperature of 180℃, an axial thermal expansion coefficient of -2 × 10⁻⁶ / K, and a thermal conductivity of 0.048 W / (m·K). The first, second, third, and fourth reinforcing members are all made of PVC foam. PVC foam provides lightweight rigid support and exhibits good durability and compressive strength. The first, second, third, and fourth reinforcing members serve to increase strength and distribute stress. Optionally, the first, second, third, and fourth reinforcing members can also be made of different materials, such as one or more of EVA foam, polyurethane foam, PE foam, PP foam, and PVC foam. The material of the corresponding reinforcing member can be selected and set according to the stress borne by each area.
[0033] In some embodiments, the aramid epoxy prepreg is a semi-solid, viscous epoxy resin.
[0034] In some embodiments, please refer to Figure 2 Step 02 further includes: Step 021: Lay the inner layer on the surface of the airbag.
[0035] Step 022: Lay the first reinforcing member, the second reinforcing member, the third reinforcing member and the fourth reinforcing member in the preset first area a, the preset second area b, the preset third area c and the preset fourth area d respectively.
[0036] Please refer to Figure 9 Preset first region a is the peripheral region where the housing 103 connects to the first arm 111. Preset second region b is the peripheral region where the housing 103 connects to the second arm 131. Preset third region c is the peripheral region where the housing 103 connects to the third arm 151. Preset fourth region d is the peripheral region where the housing 103 connects to the fourth arm 161. Preset first region a, preset second region b, preset third region c, and preset fourth region d are the main stress-bearing regions of the housing 103. The remaining regions of the housing 103 other than preset first region a, preset second region b, preset third region c, and preset fourth region d are preset fifth regions, and preset fifth region e is the secondary stress-bearing region of the housing 103.
[0037] Step 023: Lay the outer layer on the surface of the inner layer, and sandwich the inner and outer layers of the first region a with a first reinforcing member, sandwich the inner and outer layers of the second region b with a second reinforcing member, sandwich the inner and outer layers of the third region c with a third reinforcing member, and sandwich the inner and outer layers of the fourth region d with a fourth reinforcing member.
[0038] The pre-defined fifth region's secondary stress-bearing area includes an inner layer and an outer layer, both of which are two layers of aramid epoxy prepreg.
[0039] Step 03: Place the airbag with the preform on it into the mold, and inflate the airbag through the air inlet to compact the preform.
[0040] Step 04: Stop inflating the airbag and seal the inflation port, then place the mold with the preform and airbag in a curing oven to heat and cure, thus obtaining the shell.
[0041] In some embodiments, please refer to Figure 3 Step 04 includes: Step 041: Control the temperature of the curing oven to increase in a stepwise manner to cure the preform.
[0042] Step 042: After curing, open the inflation port to deflate the airbag.
[0043] Step 043: After deflation is complete, remove the airbag from the mold.
[0044] Step 044: Remove the housing 103 from the mold.
[0045] In some embodiments, please refer to Figure 4 Step 041 includes: Step 0411: Raise the temperature of the curing oven to 110°C-130°C and keep the curing oven at that temperature for two hours to carry out the first stage of curing; Step 0412: After the first stage of curing is completed, raise the temperature of the curing oven to 130°C-160°C and keep the curing oven at that temperature for three hours to carry out the second stage of curing; Step 0413: After the second stage of curing is completed, raise the temperature of the curing oven to 160°C-180°C and keep the curing oven at that temperature for three hours to carry out the third stage of curing.
[0046] It should be noted that step 041 can also be implemented in other ways, for example: please refer to Figure 5 Step 04 includes: Step 0411': Raise the temperature of the curing oven to 110°C-130°C and keep the curing oven at that temperature for two hours to carry out the first stage of curing.
[0047] Step 0412': After the first stage of curing is completed, raise the temperature of the curing oven to 130°C-160°C and keep the curing oven at that temperature for four hours to carry out the second stage of curing.
[0048] Step 0413': After the second stage of curing is completed, raise the temperature of the curing oven to 160°C-180°C and keep the curing oven at that temperature for six hours to carry out the third stage of curing.
[0049] It should be noted that step 041 can also be implemented in other ways, for example: please refer to Figure 6 Step 041 includes: Step 0411: Raise the temperature of the curing oven to 110°C-130°C and keep the curing oven at that temperature for four hours to carry out the first stage of curing.
[0050] Step 0412: After the first stage of curing is completed, raise the temperature of the curing oven to 130°C-160°C and keep the curing oven at this temperature for six hours to carry out the second stage of curing.
[0051] Step 0413: After the second stage of curing is completed, raise the temperature of the curing oven to 160°C-180°C and keep the oven at that temperature for eight hours for the third stage of curing. During the first stage of curing, it is usually necessary to keep the temperature at 110°C-130°C for two to four hours to allow the epoxy resin to begin the curing reaction and form a certain cross-linked structure. This also helps to remove moisture and volatiles from the preform, reduce air bubbles, and ensure the quality of the finished shell.
[0052] During the second stage of curing, it is usually necessary to keep the temperature at 130°C-160°C for three to six hours to increase the cross-linked structure and gradually increase the strength and hardness of the shell during the fabrication process.
[0053] During the third stage of curing, the through-channel needs to be kept at a temperature of 160°C-180°C for three to eight hours to ensure that the epoxy resin is completely cured. Complete curing can improve the strength, rigidity, heat resistance and corrosion resistance of the manufactured shell, and improve the performance of the manufactured shell in practical applications.
[0054] In this embodiment of the invention, the preform is formed by inflating the airbag and compacting it with a mold. The mold containing the preform and the airbag is then placed in a curing oven and heated to cure, resulting in the shell 103. This achieves the integral manufacturing of the shell 103, changing the traditional processing method of segmented manufacturing of the shell 103 and bonding it together. This achieves lightweight and high strength of the shell 103, and can disperse stress, avoiding stress concentration and breakage of the shell 103. The integrally manufactured shell 103 has advantages such as bending resistance, impact resistance, good toughness, light weight, and good environmental adaptability.
