Description

Technical Field

[0001] This application relates to the field of transportation vehicles, and more particularly to a vehicle skin assembly and a vehicle. Background Technology

[0002] With the rapid development of vehicle technology and the increasing popularity of vehicles, people's demands for vehicles are also rising, with aesthetics being a key focus. Piercing welding, as an important method of connecting plastic parts in vehicles, is a common design for welding brackets onto vehicle skins. Since these welded brackets often house other components such as fog lights, their hardness and strength are generally higher than that of the skin itself. After welding, the skin is often stretched and deformed at the welding area, resulting in a "weld mark" on the front of the skin, affecting its appearance.

[0003] Therefore, it is necessary to provide an improved vehicle skin assembly to solve some or all of the above-mentioned problems. Utility Model Content

[0004] This application provides an aesthetically pleasing vehicle skin assembly and a vehicle.

[0005] This application provides a vehicle skin assembly, including:

[0006] Skin body;

[0007] The bracket has a base plate and a welding area. The welding area is located on the base plate, and at least a portion of the base plate and the welding area are attached to the skin body. The welding area includes a welding part and a weakening part. The weakening part is disposed adjacent to the welding part, and the welding part can deform toward the weakening part.

[0008] Furthermore, both the welding portion and the weakening portion are provided in multiples, and they are arranged alternately.

[0009] Furthermore, along the arrangement direction of the welded portion and the weakened portion, the weakened portion is provided on both opposite sides of any welded portion.

[0010] Furthermore, the weakening portion is provided in multiple parts and is arranged at intervals around the welding portion.

[0011] Furthermore, the weakened portion includes a through hole extending through the base plate along the direction from the base plate to the skin body.

[0012] Furthermore, the weakened portion includes a groove, and along the direction from the base plate to the skin body, the thickness of the weakened portion is less than the thickness of the welded portion.

[0013] Furthermore, the groove is recessed from the side of the welding area away from the skin body;

[0014] Alternatively, the groove may be recessed from the welding area toward the skin body.

[0015] Furthermore, the bracket includes a recessed cavity, which is recessed from the side of the base plate away from the skin body, and the welding area is located on the bottom side of the recessed cavity.

[0016] Furthermore, along the direction from the base plate to the skin body, the thickness of the welded portion is less than the thickness of the skin body, and the strength of the welded portion is less than the strength of the skin body.

[0017] This application also provides a vehicle including the vehicle skin assembly described above.

[0018] Compared with the prior art, the vehicle skin assembly of this application reduces the strength of the welding area by setting a weakening part in the welding area. During the welding process, the welding part deforms towards the weakening part to release stress. This can effectively reduce the tensile force of the welding area on the skin body, reduce the degree of deformation of the skin body, and thus improve the smoothness of the outer surface of the skin body. This greatly improves the "weld mark" problem of the skin body and enhances the aesthetics of the vehicle skin assembly.

[0029] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0031] like Figure 1 and Figure 2 As shown, the vehicle skin assembly of this application includes a skin body 1 and a bracket 2. The bracket 2 is fixed to the skin body 1 and can be used to install other components, such as headlights. The bracket 2 has a base plate 21 and a welding area 22. The welding area 22 is located on the base plate 21, and the base plate 21 and the welding area 22 are at least partially attached to the skin body 1 to improve the welding strength between the bracket 2 and the skin body 1. To further improve the stability of the bracket 2, the base plate 21 can be completely attached to the skin body 1. The welding area 22 and the base plate 21 are preferably, but not limited to, integrally injection molded, which simplifies the structure between the welding area 22 and the base plate 21 and reduces manufacturing costs.

[0032] The welding zone 22 includes a welding portion 221 and a weakening portion 222. The weakening portion 222 is disposed adjacent to the welding portion 221, and the welding portion 221 can deform toward the weakening portion 222. By providing the weakening portion 222 in the welding zone 22, the strength of the welding zone 22 is reduced. During the welding process in the welding zone 22, the welding portion 221 deforms toward the weakening portion 222 to release stress. This effectively reduces the tensile force of the welding zone 22 on the skin body 1, reduces the degree of deformation of the skin body 1, and thus improves the smoothness of the outer surface of the skin body 1. This greatly improves the "weld mark" problem of the skin body 1 and enhances the aesthetics of the vehicle skin assembly.

[0033] In some embodiments, to reduce the overall strength of the welding area 22, the bracket 2 may further include a recessed cavity 23. The recessed cavity 23 is recessed from the side of the base plate 21 away from the skin body 1. The welding area 22 is correspondingly disposed in the recessed cavity 23 and located on the bottom side of the recessed cavity 23. In other words, the thickness of the welding area 22 is less than the thickness of the area of ​​the base plate 21 adjacent to the welding area 22. It is worth noting that, to ensure the fit between the base plate 21 and the welding area 22 and the skin body 1, the side of the welding area 22 facing the skin body 1 is flush with the side of the base plate 21 facing the skin body 1.

[0034] like Figure 3 As shown, along the direction from the base plate 21 to the skin body 1, the thickness of the welded portion 221 is less than the thickness of the skin body 1, and the strength of the welded portion 221 is less than the strength of the skin body 1. For example, the thickness D1 of the welded portion 221 is not greater than 1.5 mm and not less than 1 mm, and the thickness D2 of the skin body 1 is not greater than 3.5 mm and not less than 3 mm. The above is only an exemplary description, and the thickness D1 of the welded portion 221 and the thickness D2 of the skin body 1 can also be other values ​​according to actual production needs.

[0035] After the skin body 1 and the bracket 2 are welded, since the strength of the welded part 221 is less than the strength of the skin body 1, the skin body 1 is no longer stretched and deformed by the welded part 221, thereby improving the smoothness of the outer surface of the skin body 1 and greatly improving the "weld mark" problem of the skin body 1.

[0036] Multiple welded portions 221 and weakened portions 222 are provided, and they are arranged alternately. This arrangement effectively reduces the strength of the welded area 22, and also allows the welded portions 221 to effectively deform towards the weakened portions 222 during welding to release stress and reduce the tensile force on the skin body 1. To make the welded portions 221 release stress more effectively, weakened portions 222 are provided on both sides of each welded portion 221 along the arrangement direction of the welded portions 221 and the weakened portions 222.

[0037] like Figure 4 and Figure 5As shown, in some other embodiments, multiple weakening portions 222 are provided and spaced apart around the weld portion 221. This arrangement allows the weld portion 221 to release stress more comprehensively through its periphery and reduces the strength of the weld area 22. It is worth noting that when multiple weld portions 221 are provided, multiple weakening portions 222 are provided around the periphery of each weld portion 221.

[0038] like Figure 3 As shown, in some embodiments, the weakening portion 222 includes a through hole 223 that penetrates the base plate 21 along the direction from the base plate 21 to the skin body 1. Further, the weakening portion 222 is an elongated hole penetrating the welding area 22 and communicating with the recessed cavity 23. In this embodiment, the side of the welding portion 221 facing the skin body 1 is flush with the side of the base plate 21 facing the skin body 1.

[0039] like Figure 6 and Figure 7 As shown, in some other embodiments, the weakening portion 222 includes a groove 224, and the thickness of the weakening portion 222 is less than the thickness of the welding portion 221 along the direction from the base plate 21 to the skin body 1. That is, along the direction from the base plate 21 to the skin body 1, the weakening portion 222 is an elongated hole penetrating the partial welding area 22, and the bottom thickness of the weakening portion 222, which is an elongated hole, is less than the thickness of the welding portion 221. In this embodiment, the groove 224 is recessed from the side of the welding area 22 away from the skin body 1, and the groove 224 communicates with the recessed cavity 23. Admittedly, the groove 224 may also be recessed from the side of the welding area 22 towards the skin body 1.

[0040] If the groove 224 is recessed from the side of the welding area 22 toward the skin body 1, a distinguishing part 225 is provided on the side of the welding area 22 away from the skin body 1 to clearly distinguish the welded part 221 and the weakened part 222, and the distinguishing part 225 is provided corresponding to the groove 224. Specifically, the distinguishing part 225 is recessed from the side of the welding area 22 away from the skin body 1, and the welded part 221 can also deform toward the distinguishing part 225 to release stress.

[0041] The skin body 1 can be a bumper skin, fender, etc., and this article does not limit it.

[0042] This application also provides a vehicle including the vehicle skin assembly described above.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
