[0036] The preferred embodiments of the utility model are described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the utility model, and are not intended to limit the protection scope of the utility model.
[0037] It should be noted that in the description of the utility model, the terms "inner", "outer", "upper", "lower" and the like indicating the direction or positional relationship of the terms are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and is not intended to indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0038] In addition, it should be noted that in the description of the utility model, unless otherwise explicitly specified and limited, the terms "set", "connected", "mounted" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0039] The welding quality between the tail lamp plate and the side outer plate of the existing vehicle is not ideal based on the background technology. The utility model provides a tail lamp plate of a vehicle and a vehicle, which aims to set a support surface which is not attached to the side outer plate and a welding surface which forms a certain angle with the side outer plate on the tail lamp plate, so that the edge of the first side turning edge forms a linear weld with the inclined welding surface, and a first gap for zinc vapor overflow is formed inside the weld, ensuring the stable escape of zinc vapor during welding and avoiding the formation of pores at the weld to affect the welding quality.
[0040] In recent years, as users have higher and higher requirements for the safety and energy saving of vehicles, a large number of sheet metals of many vehicle models are made of galvanized plates, which are connected and fixed by laser welding, so that the vehicle body not only has good corrosion resistance and oxidation resistance, prolonging its service life, but also has high strength and ductility, improving the overall strength of the vehicle body.
[0041] However, when laser welding each part of the vehicle body, the zinc layer on the surface of the galvanized plate will vaporize at high temperature, and if the zinc vapor cannot escape in time, pores will be formed in the weld, which not only reduces the effective cross-sectional area and welding strength of the weld, but also may cause leakage and increase the repair cost.
[0042] For example, in order to adapt to more and more complex tail lamp shapes and vehicle body structures, the tail lamp plate of the existing vehicle is also set to a complex configuration, so that it is easily limited by space and structure during laser welding with the side outer plate, which makes it difficult for zinc vapor to overflow, thereby affecting the welding quality.
[0043] Based on this, as Figure 1 shown, the tail lamp plate 1 is composed of three galvanized plates, namely a first galvanized plate, a second galvanized plate and a third galvanized plate. Compared with the whole tail lamp plate 1 structure, the split tail lamp plate 1 has better adaptability and can match more complex tail lamp shapes and vehicle body structures.
[0044] At least one turning edge is provided on each galvanized plate to connect with the side outer plate 2. Correspondingly, a plurality of side turning edges are provided on the side outer plate 2, and the fixed connection between the tail lamp plate 1 and the side outer plate 2 is realized by the mutual connection of the plurality of turning edges and the plurality of side turning edges. The first turning edge 11 on the first galvanized plate is used to weld and fix the first side turning edge 21 on the outermost side of the side outer plate 2.
[0045] Specifically, as Figures 1 to 4As shown, a plurality of support surfaces 112 and welding surfaces 111 are arranged on the first flange 11 in an alternating manner along the length direction, and the two are smoothly connected, the welding surface 111 is an inclined surface structure arranged obliquely relative to the support surface 112, that is, a certain angle is formed between the two, so that the part of the welding surface 111 close to the edge protrudes from the support surface 112 to form a protruding part 1111, and the part of the welding surface 111 away from the edge is recessed in the support surface 112 to form a sunken part 1112.
[0046] In assembly, as shown, Figures 4 to 6 When the first flange 11 is overlapped with the side outer plate 2, the first side flange 21 is simultaneously zero-fitted with a plurality of support surfaces 112, and the edge of the first side flange 21 is overlapped on the protruding part 1111 to form a weld 32, so that under the common support of the protruding part 1111 and the support surfaces 112 on both sides, a stable first gap 31 is formed between the first side flange 21 and the sunken part 1112 inside the weld 32, so that when the welding gun welds the weld 32 from the outside, the zinc vapor can stably escape through the first gap 31 on the inside. Preventing zinc vapor from forming pores in the weld 32 to reduce the effective cross-sectional area and welding strength of the weld 32, and improving the welding quality.
[0047] It should be noted that the angle between the welding surface 111 and the support surface 112 can be flexibly set to 3° to 9°, and the present scheme is preferably set to 6°. In this way, it can not only ensure the stable escape of zinc vapor, but also reduce the processing difficulty as much as possible and reduce the space occupation.
[0048] In addition, the effective support of the support surface 112 to the first side flange 21 also ensures the stable contact of the side outer plate 2 and the tail lamp plate 1 at the weld 32, preventing gaps from occurring at the weld 32 to affect the welding quality.
[0049] Compared with other gas escape schemes, the tail lamp plate 1 in the present scheme does not need to add complex structures to realize the stable escape of gas, thereby reducing the processing difficulty of the tail lamp plate 1.
[0050] Preferably, as shown, Figures 1 to 4 The welding surface 111 on the first flange 11 in the present application is provided with two, and the two sides of each welding surface 111 are provided with support surfaces 112, thereby improving the stability and welding strength in the welding process through the multi-point welding and support between the first flange 11 and the first side flange 21.
[0051] The length of the weld 32 formed between each welding surface 111 and the edge of the side outer plate 2 is preferably set to 15mm, which not only meets the strength requirement of the vehicle body for welding, but also controls the welding cost.
[0052] Preferably, multiple adhesive application areas (not shown in the figure) are provided along the edge of the taillight panel 1. By applying structural adhesive to the adhesive application areas, the adhesive application areas can be bonded to the side panel 2, thereby effectively supplementing the laser welding and further improving the connection stability between the taillight panel 1 and the side panel 2.
[0053] Preferably, such as Figure 1 As shown, this utility model provides a second flange 12 on the second galvanized plate. The second flange 12 is used to connect with the second side flange on the inner side of the outer side panel 2. Specifically, the second flange 12 and the second side flange are also fixed by welding, realizing a multi-point connection between the taillight plate 1 and the outer side panel 2, and improving the stability of the connection between the two. It should be noted that its specific structure can also be set to a structure similar to the first flange 11, which will not be described in detail here.
[0054] like Figure 2 As shown, a plurality of positioning holes 13 are also provided on the taillight plate 1. In this application, the number of positioning holes 13 is preferably set to two. The taillight plate 1 can be fixed during stamping, welding or testing through the two positioning holes 13 to ensure its processing and assembly accuracy.
[0055] During the processing and assembly of the side panel 2 and the taillight panel 1, tolerances are unavoidable. Preferably, the first side flange 21 of the side panel 2 and the welding surface 111 are both controlled to have positive tolerances. This setting ensures that the edge of the first side flange 21 and the welding surface 111 are close to each other, thereby ensuring that the two are tightly fitted at the weld 32 to form a stable line contact, preventing gaps at the weld 32 from affecting the welding quality.
[0056] Furthermore, the vehicle provided by this utility model, based on the aforementioned taillight panel, possesses the technical effects of the aforementioned taillight panel due to the adoption of the aforementioned taillight panel. Compared to the vehicle before the improvement, the vehicle of this utility model, while satisfying the complex shape of the taillights, improves the welding quality and reduces the stamping and welding difficulty of the taillight panel.
[0057] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
