[0027] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0028] Reference below Figure 1-Figure 4 An interior connection structure 10 for a vehicle according to an embodiment of the present application is described. The interior connection structure 10 includes a first interior part 11 and a second interior part 12. A first matching portion 111 is formed on the first interior part 11 and is arranged to penetrate in a first direction. A second matching portion 121 extending in the first direction is provided on a side of the second interior part 12 facing the first interior part 11. At least a portion of the second matching portion 121 passes through the first matching portion 111. A welding portion 122 is formed at the free end of the second matching portion 121. The welding portion 122 extends in the second direction and is welded and fixed to a side of the first interior part 11 away from the second interior part 12. A first hole portion 123 extending in the first direction is also formed on the second matching portion 121. The first direction is orthogonal to the second direction.

[0029] At present, the main fastening forms between vehicle interior product components are clamping, welding and screwing. Clamping is mainly used in the assembly process, but wear and deformation after more than three disassembly and assembly will cause the clamping strength to decay, and it cannot meet the fastening strength requirements of multiple disassembly and assembly. Welding can improve the structural strength, but the interior product components cannot be fastened a second time after welding, which does not meet the disassembly and assembly requirements. Screw connection can meet the multiple disassembly and assembly of the product with less fastening force attenuation, but the actual application process The proportion of product disassembly needs is small, there is waste, and the weight of screws is relatively high, which is not conducive to the lightweight development of products.

[0030] like Figure 1 As shown, specifically, the interior connection structure 10 includes a first interior decoration part 11 and a second interior decoration part 12. The first interior decoration part 11 and the second interior decoration part 12 can be constructed as injection molded parts. A first matching portion 111 is formed on the first interior decoration part 11 and is arranged to penetrate in a first direction. A second matching portion 121 is arranged on a side of the second interior decoration part 12 facing the first interior decoration part 11. The second matching portion 121 can extend in the first direction, and at least a portion of the second matching portion 121 can be passed through the first matching portion 111. A welding portion 122 can be formed at the free end of the second matching portion 121. The welding portion 122 can extend in a second direction, and the second direction is orthogonal to the first direction. The welding portion 122 can be welded and fixed to a side of the first interior decoration part 11 away from the second interior decoration part 12, thereby achieving fixation between the first interior decoration part 11 and the second interior decoration part 12. The use of welding fixation can also improve the connection strength between the first interior decoration part 11 and the second interior decoration part 12.

[0031] Furthermore, a first hole portion 123 extending in the first direction is formed on the second matching portion 121, and the first hole portion 123 can cooperate with the fastener 13 to achieve a detachable connection between the first interior decoration component 11 and the second interior decoration component 12. In a specific embodiment, when welding, the staff first adjusts the position of the welding portion 122 to extend the welding portion 122 in the second direction, and a welding surface 112 is formed on the side of the first interior decoration component 11 away from the second interior decoration component 12, and then the contact surface between the welding portion 122 and the welding surface 112 is welded and fixed. At this time, the first interior decoration component 11 and the second interior decoration component 12 are fixedly connected. When the first interior decoration component 11 or the second interior decoration component 12 needs to be disassembled or replaced, the staff can remove the welding portion 122, and then cooperate with the fastener 13 and the first hole portion 123 to achieve a detachable connection between the first interior decoration component 11 and the second interior decoration component 12, so that the interior connection structure 10 meets the disassembly requirements.

[0032] In short, the interior connection structure 10 of the embodiment of the present application has a first interior decoration part 11 and a second interior decoration part 12, a first matching portion 111 is formed on the first interior decoration part 11, a second matching portion 121 penetrating the first matching portion 111 is formed on the second interior decoration part 12, a welding portion 122 is formed at the free end of the second matching portion 121 for welding and fixing to the first interior decoration part 11, and a first hole portion 123 matching with the fastener 13 is also formed on the second matching portion 121. Therefore, the interior connection structure 10 can improve the matching strength between the first interior decoration part 11 and the second interior decoration part 12, realize a lightweight design, and when the interior connection structure 10 needs to be disassembled, it can be fixed multiple times through the first hole portion 123, meeting the disassembly requirements.

[0033] like Figure 2 As shown, in some embodiments of the present application, the interior connection structure 10 further includes a fastener 13, which can be arranged on the side of the second interior decoration 12 facing the first interior decoration 11, and the fastener 13 can be inserted into the first matching portion 111 and matched with the first hole portion 123. When the first interior decoration 11 or the second interior decoration 12 needs to be disassembled or replaced, the staff can remove the welding portion 122, and then match the fastener 13 with the first hole portion 123 to achieve a detachable connection between the first interior decoration 11 and the second interior decoration 12. In a specific embodiment, the fastener 13 can be configured as a screw. Further, the inner wall of the first hole portion 123 can be formed with a first threaded portion, and the outer peripheral wall of the fastener 13 can be formed with a second threaded portion. The first threaded portion and the second threaded portion can be matched by threads. The use of threaded connection can reduce the difficulty of assembly and disassembly and improve the efficiency of assembly and disassembly.

[0034] In some embodiments of the present application, the fastener 13 can be constructed as a self-tapping screw, which can be directly screwed into the first hole portion 123 without pre-drilling, thereby simplifying the installation process, saving time, and improving work efficiency.

[0035] like Figure 3 As shown, in some embodiments of the present application, the welding portion 122 is constructed as a ring extending in the circumferential direction of the first mating portion 111. By constructing the welding portion 122 as a ring, the contact area between the welding portion 122 and the welding surface 112 can be increased, thereby improving the mating strength between the first interior decoration component 11 and the second interior decoration component 12.

[0036] like Figure 3As shown, in some embodiments of the present application, a second hole portion 124 is further formed on the welding portion 122, and the second hole portion 124 can extend in the first direction, and the second hole portion 124 can be arranged corresponding to the first hole portion 123. The second hole portion 124 can enable the welding portion 122 to deform and bend toward the second direction during welding, so that the welding portion 122 can fit the welding surface 112. Further, the inner diameter of the first hole portion 123 is D1, and the inner diameter of the first hole portion 123 can meet the following conditions: 3mm≤D1≤3.6mm, the inner diameter of the second hole portion 124 is D2, and the inner diameter of the second hole portion 124 can meet the following conditions: 3.7mm≤D2≤4.3mm. By setting the inner diameter D1 of the first hole portion 123 and the inner diameter D2 of the second hole portion 124 within the above-mentioned ranges respectively, it can be ensured that the first hole portion 123 can effectively cooperate with the fastener 13, and the second hole portion 124 can reduce the hardness of the welding portion 122, so that the welding portion 122 is more easily deformed and bent.
