Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically, to a non-metallic vehicle body side panel device. Background Technology

[0002] In the platform-based development of new energy vehicles, various side panel sheet metal structures are typically required to meet the height differences and cabin space requirements of different models. In the platform-based development of traditional heavy-duty trucks, metal materials are commonly used to manufacture the body side panels. However, the development cost of a single set of molds for such metal side panels is as high as 5-6 million yuan, and the development cycle is long, typically exceeding 240 days, severely restricting the flexibility of vehicle development and the speed of response to market changes.

[0003] Furthermore, the limitations of sheet metal structures in terms of material properties and manufacturing processes restrict the expansion of vertical space within the vehicle, hindering the optimization of the overall space layout. Simultaneously, the significant weight of metal materials increases the overall vehicle weight, negatively impacting fuel economy and performance. To meet structural strength and vibration control requirements, traditional designs necessitate the addition of auxiliary components such as locally reinforcing crossbeams and shock-absorbing damping plates within the side panels, further increasing structural complexity and unit cost.

[0004] Therefore, existing technologies suffer from problems such as high development costs, long development cycles, limited space layout, large vehicle weight, and complex structures. There is an urgent need for a new type of vehicle side panel device and development method to improve the economy and adaptability of platform-based development. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a non-metallic vehicle body side panel device, which improves versatility and assembly efficiency through modular and integrated installation, and reduces development costs and cycle by using non-metallic materials, thereby achieving lightweighting and space optimization.

[0006] The present invention solves the above problems through the following technical solution:

[0007] A non-metallic vehicle side panel device includes: a modular non-metallic side panel body; a plurality of integrated buckles are detachably provided on the inner side of the modular non-metallic side panel body for pre-fixing by cooperating with buckle bases on the vehicle body sheet metal; an annular adhesive application surface is formed on the inner edge of the modular non-metallic side panel body, and an adhesive application groove is formed on the side of the annular adhesive application surface away from the modular non-metallic side panel body. By injecting single-component polyurethane adhesive into the adhesive application groove and bonding and curing it with the cab side panel sheet metal to form a cured sealing layer, the vehicle side panel device is pasted and installed on the cab side panel sheet metal.

[0008] As a further improvement, the integrated buckle is provided in a number of four, and is circumferentially arranged inside the modular non-metallic side panel body.

[0009] As a further improvement, the modular non-metallic side panel body has a mounting boss at the location where the integrated buckle is installed, and an internal thread is formed in the mounting boss to facilitate threaded connection of the integrated buckle.

[0010] As a further improvement, an anti-overflow strip is provided on the side of the annular adhesive application surface away from the modular non-metallic side panel body, and the anti-overflow strip is located close to the edge of the modular non-metallic side panel body.

[0011] As a further improvement, the anti-overflow strip is attached to the modular non-metallic side panel body using 3M adhesive.

[0012] As a further improvement, the body sheet metal includes an inner C-pillar panel and an inner B-pillar panel, and the inner C-pillar panel, the inner B-pillar panel, and the upper and lower cab side panel sheet metal form an enclosing structure. The enclosing structure is used to cooperate with the cured sealing layer and the anti-overflow rubber strip for installation.

[0013] As a further improvement, the inner panels of the C-pillar and B-pillar are respectively provided with the buckle base.

[0014] As a further improvement, the glue-applying groove is arranged circumferentially along the modular non-metallic side panel body and is stepped.

[0015] As a further improvement, the annular adhesive surface is integrally formed with the modular non-metallic side panel body.

[0016] As a further improvement, the modular non-metallic sidewall body is made of glass fiber reinforced plastic.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] (1) This utility model improves versatility and assembly efficiency through modular and integrated installation: the modular non-metallic side panel body is combined with a unified side panel sheet metal structure to achieve adaptation to different vehicle requirements on the same chassis and support multi-vehicle platform development. The integrated buckle enables quick pre-positioning with the body sheet metal, and then a single-component polyurethane adhesive is injected through the glue applicator to form a cured sealing layer, which not only ensures installation strength and sealing performance, but also simplifies the assembly process and improves production consistency and reliability.

[0019] (2) This utility model uses non-metallic materials to reduce development costs and cycle: The modular non-metallic side panel body is made of resin mixed with glass fiber material by hot pressing, which greatly reduces the mold development cost to RMB 200,000-300,000, far lower than the RMB 5 million-6 million of traditional metal molds, and the benefit ratio is increased to 20-25 times. At the same time, the design and mold opening cycle is shortened from the original more than 240 days to about 80 days, which significantly improves development efficiency and reduces labor and time costs.

[0020] (3) This utility model achieves lightweighting and space optimization: the non-metallic material effectively reduces the weight of the components while meeting the structural performance requirements. In addition, the non-metallic side panel has high design flexibility, eliminates the restriction on the vertical space inside the vehicle, which is conducive to expanding the cabin space, and eliminates the need for the local reinforcing beams and shock-absorbing damping plates set up in traditional metal side panels to enhance rigidity and vibration reduction, further simplifying the structure.

[0021] (4) This utility model can reduce costs and maintain performance: While controlling the cost of a single piece, this utility model achieves comprehensive performance comparable to or even better than traditional metal side panels through material and structure optimization, solving the problems of high cost, long cycle and structural redundancy caused by material and process limitations in traditional technology.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Combined with appendix Figure 1-3 As shown, a non-metallic vehicle body side panel device 3 includes:

[0029] The modular non-metallic side panel body 3-1 has several detachable and installable integrated buckles 3-2 arranged circumferentially on its inner side for connection with the vehicle body; an annular adhesive application surface 3-3 is formed on the inner edge of the modular non-metallic side panel body 3-1, and an adhesive application groove 3-3-1 is formed on the annular adhesive application surface 3-3 away from the modular non-metallic side panel body 3-1. A curing sealing layer 3-4 and an anti-overflow adhesive strip 3-5 are arranged on the side of the annular adhesive application surface 3-3 away from the modular non-metallic side panel body 3-1, and the curing sealing layer 3-4 is arranged in the adhesive application groove 3-3-1, and the anti-overflow adhesive strip 3-5 is arranged close to the edge of the modular non-metallic side panel body 3-1.

[0030] As a preferred option, the modular non-metallic side panel body 3-1 is made of glass fiber reinforced plastic, which is a fiber-reinforced thermosetting composite material. The main materials are resin and glass fiber. The strength of the molded side panel body can be increased by adjusting the length and content of glass fiber.

[0031] The glue application groove 3-3-1 is set around the modular non-metallic side panel body 3-1 in a stepped shape with a width of 8-12mm.

[0032] The curing and sealing layer 3-4 is formed by filling the caulking groove 3-3-1 with single-component polyurethane adhesive using a caulking gun, and after curing, it forms an integrated structure-seal interface.

[0033] The anti-overflow strip 3-5 is used to prevent the cured sealant 3-4 from overflowing from the bonding area before the single-component polyurethane adhesive cures and takes effect, and is attached to the modular non-metallic side panel body 3-1 with 3M adhesive.

[0034] The annular adhesive surface 3-3 is integrally formed with the modular non-metallic side body 3-1. In this embodiment, the annular adhesive surface 3-3 is made of a lightweight PU foam material. After being pre-made, it is placed in a fiberglass mold and integrally formed with the modular non-metallic side body 3-1. The resin and fiberglass mixture of the modular non-metallic side body 3-1 will wrap it in the hot melt state to form an integrated structure.

[0035] In an optional embodiment, the modular non-metallic side panel body 3-1 has a mounting boss at the location where the integrated snap-fit ​​3-2 is mounted, and an internal thread is formed in the mounting boss to facilitate threaded connection of the integrated snap-fit ​​3-2.

[0036] Cab side panel sheet metal: The welded assembly of the inner and outer sheet metal panels on the left and right sides of the cab.

[0037] The inner C-pillar panel 4 and inner B-pillar panel 2 of the vehicle body sheet metal, along with the upper and lower cab side panel 1, form an enclosing structure. This enclosing structure is used to abut and cooperate with the cured sealing layer 3-4 and the anti-overflow adhesive strip 3-5 during installation. The inner C-pillar panel 4 and inner B-pillar panel 2 are respectively provided with clip bases that cooperate with the integrated clip 3-2.

[0038] During assembly, firstly, single-component polyurethane adhesive is injected into the adhesive groove of the annular adhesive surface 3-3 to form a cured sealing layer 3-4. Then, the entire non-metallic vehicle side panel device 3 is pre-fixed to the cab side panel sheet metal 1 along the assembly direction via integrated clips 3-2 and clip bases. The cured sealing layer 3-4 and anti-overflow adhesive strip 3-5 are pressed against the sheet metal adhesive surface 1-1 of the cab side panel sheet metal 1. The cured sealing layer 3-4 needs to be cured at room temperature for 24 hours to form an adhesive layer with a shear strength ≥3.5MPa. After the cured sealing layer 3-4 is completely dry and cured, a cured sealing layer 3-4 with a shear strength ≥3.5MPa is formed. The non-metallic vehicle side panel device 3, the cab side panel sheet metal 1, the B-pillar inner panel 2, and the C-pillar inner panel 4 form an integrated side panel structure.

[0039] This utility model achieves mechanical positioning through the cooperation of a snap-fit ​​base and an integrated snap-fit ​​3-2, with a tolerance of ±0.5mm; a continuous sealing barrier is formed on the annular adhesive surface 3-3, with an airtightness of ≤5 cm³ / min; and the same set of non-metallic body side panel device 3 can be adapted to different market demands for vehicle models, demonstrating wide adaptability; by replacing different non-metallic body side panel devices, the same side panel sheet metal can be used, enabling interchangeability between "high-profile" and "low-profile" vehicles. It simultaneously and cost-effectively increases interior space or reduces overall vehicle height.

[0040] By using a modular non-metallic side panel body integrated snap-fit ​​structure and annular glue-applying groove, combined with single-component polyurethane adhesive curing, a sealed-structure integrated interface is formed. This solves the technical problems of high mold cost and poor adaptability of side panel components in the platform development of new energy heavy-duty trucks, reducing mold development costs by 5 million yuan per vehicle model, while improving cabin space utilization and adapting to the needs of more niche markets.

[0041] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
