Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] See Figures 1 to 4 The tailgate assembly 1 includes a tailgate inner panel 10, a cover plate 20, and a first adhesive layer 30.

[0022] The tailgate inner panel 10 has an opening 11 corresponding to the windshield 40 and a mounting surface 12. The cover plate 20 is located on one side of the mounting surface 12 of the tailgate inner panel 10. The cover plate 20 includes a first cover plate portion 210, a second cover plate portion 220 and a third cover plate portion 230. The first cover plate portion 210, the second cover plate portion 220 and the third cover plate portion 230 surround the opening 11. The first cover plate portion 210 and the third cover plate portion 230 are located on opposite sides of the opening 11. The second cover plate portion 220 connects the first cover plate portion 210 and the third cover plate portion 230. The first adhesive layer 30 is located between the cover plate 20 and the tailgate inner panel 10. The cover plate 20 is bonded to the tailgate inner panel 10 through the first adhesive layer 30.

[0023] Specifically, the windshield 40 covers the opening 11 of the tailgate inner panel 10, allowing the driver to observe the rear situation through the windshield 40. The windshield 40 is fixedly connected to the cover plate 20, which is shaped like a "Z" and located on one side of the mounting surface 12 of the tailgate inner panel 10. The first cover plate portion 210, the second cover plate portion 220, and the third cover plate portion 230 of the cover plate 20 surround the opening 11. The first cover plate portion 210, the second cover plate portion 220, and the third cover plate portion 230 are fixedly connected to the windshield 40. The first cover plate portion 210, the second cover plate portion 220, and the third cover plate portion 230 are bonded to the tailgate inner panel 10 through the first adhesive layer 30. By adjusting the thickness of the first adhesive layer 30, the influence of the deformation error of the tailgate inner panel 10 on the windshield 40 or other structures is reduced. The first cover plate 20 and the tailgate inner panel 10 provide support for the windshield 40.

[0024] In this application, the first cover plate portion 210, the second cover plate portion 220, and the third cover plate portion 230 of the cover plate 20 are disposed around the opening 11 of the tailgate inner panel 10. The first cover plate portion 210 and the third cover plate portion 230 are located on opposite sides of the opening 11. The first cover plate portion 210 and the third cover plate portion 230 are fixedly connected to the tailgate inner panel 10, and at the same time, the first cover plate portion 210 and the third cover plate portion 230 are fixedly connected to the windshield 40. The overall size of the tailgate inner panel 10 and the cover plate 20 is adjusted by the variable height of the first adhesive layer 30, which reduces the impact of warping deformation of the tailgate inner panel 10 on the accuracy and improves the installation accuracy of the tailgate assembly 1. At the same time, the strength of the tailgate assembly 1 is improved by the first cover plate portion 210, the second cover plate portion 220, and the third cover plate portion 230.

[0025] See Figure 3 In one embodiment, the cover plate 20 is provided with a first opening 201, and the tailgate inner panel 10 is provided with a second opening 101. The locking member 50 passes through the first opening 201 and the second opening 101 to lock the cover plate 20 and the tailgate inner panel 10.

[0026] Specifically, the locking member 50 passes through the first opening 201 of the cover plate 20 and the second opening 101 of the tailgate inner panel 10 to fix the cover plate 20 and the tailgate inner panel 10. The first adhesive layer 30 is used to bond the cover plate 20 and the tailgate inner panel 10. The connection strength between the cover plate 20 and the tailgate inner panel 10 is enhanced by the mechanical connection of the locking member 50 and the bonding of the first adhesive layer 30.

[0027] See Figure 3 In one embodiment, the first cover plate portion 210 is provided with a first opening 201, and the locking member 50 passes through the first opening 201 and the second opening 101 to lock the first cover plate portion 210 and the tailgate inner panel 10. In another embodiment, the second cover plate portion 220 is provided with a first opening 201, and the locking member 50 passes through the first opening 201 and the second opening 101 to lock the second cover plate portion 220 and the tailgate inner panel 10. In yet another embodiment, the third cover plate portion 230 is provided with a first opening 201, and the locking member 50 passes through the first opening 201 and the second opening 101 to lock the third cover plate portion 230 and the tailgate inner panel 10.

[0028] See Figure 3 In one embodiment, the locking member 50 includes screws, bolts, or rivets. For example, the rivet passes through the first opening 201 and the second opening 101 to lock the cover plate 20 and the tailgate inner panel 10. Alternatively, the screw passes through the first opening 201 and the second opening 101 to lock the cover plate 20 and the tailgate inner panel 10. Or, the bolt passes through the first opening 201 and the second opening 101 to lock the cover plate 20 and the tailgate inner panel 10.

[0029] See Figure 3In one embodiment, the tailgate assembly 1 further includes an outer spoiler plate 610 and an inner spoiler plate 620. The outer spoiler plate 610 is located on the side of the cover plate 20 away from the mounting surface 12, and the inner spoiler plate 620 is located on the side of the outer spoiler plate 610 close to the mounting surface 12, covering the first cover plate portion 210 and the third cover plate portion 230. The outer spoiler plate 610 and the inner spoiler plate 620 are fixedly connected, and the inner spoiler plate 620 is fixedly connected to the first cover plate portion 210 and the third cover plate portion 230.

[0030] Specifically, the inner spoiler plate 620 is located on the side of the cover plate 20 away from the mounting surface 12, and the outer spoiler plate 610 is located on the side of the inner spoiler plate 620 away from the mounting surface 12. The outer spoiler plate 610 is fixedly connected to the inner spoiler plate 620, and the inner spoiler plate 620 is fixedly connected to the first cover plate portion 210 and the third cover plate portion 230. The first cover plate portion 210 and the third cover plate portion 230 form a rigid support frame, which solves the deformation problem caused by the long cantilever formed between the inner spoiler plate 620 and the tailgate inner plate 10.

[0031] See Figure 3 In one embodiment, the locking member 50 passes through the tailgate inner panel 10, the cover plate 20 and the spoiler inner panel 620 in sequence, and fixes the tailgate inner panel 10, the cover plate 20 and the spoiler inner panel 620 together.

[0032] See Figure 2 In one embodiment, the first cover plate portion 210, the second cover plate portion 220 and the third cover plate portion 230 are integrally formed structures.

[0033] Specifically, the first cover plate 210, the second cover plate 220, and the third cover plate 230 are a single integral component, meaning the cover plate 20 is a single integral component. The cover plate 20 is manufactured using an integrated molding process, significantly reducing the number of components and simplifying the assembly process. Furthermore, since there are no seams or connection points, the integrated cover plate 20 achieves a more continuous and uniform material distribution and stress transfer. When the cover plate 20 is subjected to external loads, stress will not concentrate at the joints, effectively avoiding the risk of structural deformation or cracking due to weak joints. This results in a stronger overall rigidity of the cover plate 20, making it more resistant to bending, torsion, and vibration, providing more reliable structural support and protection for the tailgate inner panel 10.

[0034] In one embodiment, the first cover plate portion 210 and the third cover plate portion 230 are symmetrically distributed along the central axis of the cover plate 20, which helps to bring the center of gravity of the cover plate 20 closer to the central axis and reduce the risk of tilting of the cover plate 20.

[0035] See Figure 3In one embodiment, a second adhesive layer 70 is provided on one side of the first cover plate portion 210 and the third cover plate portion 230, and the second adhesive layer 70 connects the cover plate 20 and the windshield 40.

[0036] Specifically, a second adhesive layer 70 is provided on the side of the first cover plate portion 210 and the third cover plate portion 230 away from the mounting surface 12. The second adhesive layer 70 is used to bond the first cover plate portion 210 to the windshield 40, and to bond the third cover plate portion 230 to the windshield 40, thereby fixing the windshield 40 to the cover plate 20. Compared to directly installing the windshield 40 onto the tailgate inner panel 10, the second adhesive layer 70 in this application connects the cover plate 20 and the windshield 40, which can reduce the length of the non-transparent area of ​​the windshield 40, thereby reducing the weight of the windshield 40.

[0037] In one embodiment, the material of the second adhesive layer 70 includes silicone sealant, a silicone sealant specifically designed for bonding various substrates such as windshield 40, stone, ceramic tiles, and metal. It possesses excellent adhesive strength and can effectively bond the windshield 40 and other substrates firmly together. The silicone sealant not only serves an adhesive function but also exhibits excellent waterproof, weather-resistant, and aging-resistant properties. It can form a continuous and dense sealing layer on the bonding surface, effectively preventing moisture and dust intrusion. By bonding the cover plate 20 and the windshield 40 with silicone sealant, not only is the connection strength between the cover plate 20 and the windshield 40 improved, but the sealing performance of the tailgate assembly 1 is also enhanced.

[0038] In one embodiment, the material of the tailgate inner panel 10 includes a composite material, and the material of the cover plate 20 includes a composite material.

[0039] Specifically, the tailgate inner panel 10 and the cover plate 20 are both formed by injection molding of composite materials, which makes the tailgate inner panel 10 and the cover plate 20 lightweight, with good toughness and corrosion resistance. The cover plate 20 and the tailgate inner panel 10 are fixedly connected in the tailgate assembly 1. The cover plate 20 enhances the rigidity and strength of the tailgate assembly 1, so that the tailgate assembly 1 can have a certain strength while being lightweight, thus optimizing the structure of the tailgate assembly 1.

[0040] In other embodiments, the tailgate inner panel 10 may also be made of metal, and the cover 20 may be made of composite material. Alternatively, the tailgate inner panel 10 may also be made of composite material, and the cover 20 may be made of metal.

[0041] In one embodiment, the material of the tailgate inner panel 10 includes at least one of long glass fiber reinforced polypropylene, glass fiber, and carbon fiber.

[0042] Specifically, the material of the tailgate inner panel 10 includes one or more of the following: long glass fiber reinforced polypropylene, glass fiber, and carbon fiber. The tailgate inner panel 10 can be long glass fiber reinforced polypropylene, glass fiber, carbon fiber, or a mixture of long glass fiber reinforced polypropylene and carbon fiber. Long glass fiber reinforced polypropylene is a composite material made by adding a large number of long glass fibers to a polypropylene matrix. Polypropylene itself is relatively soft; the addition of long glass fibers significantly improves the bending strength and rigidity of the tailgate inner panel 10 due to the high strength and modulus of the glass fibers, making it stronger and less prone to deformation. Therefore, using long glass fiber reinforced polypropylene for the tailgate inner panel 10 can reduce weight and increase strength.

[0043] In one embodiment, the material of the cover plate 20 includes at least one of long glass fiber reinforced polypropylene, glass fiber, and carbon fiber.

[0044] Specifically, the material of the cover plate 20 includes one or more of long glass fiber reinforced polypropylene, glass fiber, and carbon fiber. The cover plate 20 can be long glass fiber reinforced polypropylene, glass fiber, carbon fiber, or a mixture of long glass fiber reinforced polypropylene and carbon fiber. Using long glass fiber reinforced polypropylene for the cover plate 20 can reduce weight and increase strength.

[0045] In one embodiment, the material of the first adhesive layer 30 includes at least one of two-component polyurethane, epoxy resin, and acrylate.

[0046] Specifically, the material of the first adhesive layer 30 includes one or more of two-component polyurethane, epoxy resin, and acrylate. The material of the first adhesive layer 30 can be epoxy resin, two-component polyurethane, acrylate, or a mixture of epoxy resin and acrylate. Two-component polyurethane is an adhesive composed of a main agent and a curing agent. The main agent contains isocyanate, and the curing agent contains active hydrogen. After mixing, the main agent and curing agent undergo a chemical reaction and cure, forming a tough and elastic polymer network. Two-component polyurethane exhibits excellent adhesion to various substrates such as metals and plastics, and possesses high shear strength, good flexibility, excellent weather resistance, and durability. The material of the first adhesive layer 30, being two-component polyurethane, can improve the bonding strength between the tailgate inner panel 10 and the cover plate 20. Epoxy resin has good bonding strength to metals and composite materials, and also possesses chemical resistance and durability. The material of the first adhesive layer 30, being epoxy resin, improves the bonding strength between the tailgate inner panel 10 and the cover plate 20.

[0047] This application also protects a vehicle that includes a tailgate assembly 1 as described in any of the above claims. The vehicle includes gasoline-powered vehicles, electric vehicles, hybrid vehicles, and hydrogen fuel cell vehicles, and also includes sedans, SUVs, and commercial vehicles, etc. It should be noted that this application does not limit the type of vehicle.
