[0029] In the related art, the vehicle's exterior trim panel and the mounting bracket of the exterior trim panel are connected through an ultrasonic welding process. The ultrasonic welding process uses the principle of vibration to make the exterior trim panel and the mounting bracket at least partially fuse to achieve the connection and fixation of the exterior trim panel and the mounting bracket. However, during the welding process, weak welding strength may cause the product to open and affect performance; high welding strength may cause the product surface to deform, resulting in bulging on the exterior trim panel and uneven light and shadow.

[0030] Reference below Figure 1 An exterior trim panel 1 for a vehicle according to an embodiment of the present invention is described.

[0031] like Figure 1 As shown, the exterior trim panel 1 according to the utility model includes: a panel body 10 and a bracket 20, wherein the two surfaces of the panel body 10 in the thickness direction are respectively an appearance surface 11 and a mounting surface, wherein a first welding portion 12 protruding from the mounting surface is arranged on the mounting surface, the bracket 20 is arranged on the mounting surface, and a second welding portion 21 is arranged on the bracket 20; wherein the first welding portion 12 is at least partially fused with the second welding portion 21 to connect the panel body 10 with the bracket 20.

[0032] In some embodiments, one surface of the plate body 10 in the thickness direction is constructed as a mounting surface, which is suitable for welding with the bracket 20 and the plate body 10 is connected to the vehicle body through the bracket 20, and another surface of the plate body 10 in the thickness direction is constructed as an appearance surface 11, which is suitable for being directly viewed by users for judging the aesthetics of the vehicle body.

[0033] A first welding portion 12 is provided on the mounting surface, the first welding portion 12 protrudes from the mounting surface and extends in a direction away from the plate body 10. A bracket 20 is also provided on the mounting surface, and a second welding portion 21 is provided on the bracket 20. At least a portion of the first welding portion 12 and at least a portion of the second welding portion 21 are suitable for being melted together under an ultrasonic welding process, so that the first welding portion 12 is fixed to the second welding portion 21, and the plate body 10 and the bracket 20 are connected and fixed.

[0034] It is worth noting that the extension direction of the first welding portion 12 may be parallel to the thickness direction, and the extension direction of the first welding portion 12 may also intersect with the thickness direction, which is not limited here.

[0035] In the prior art, the plate body and the bracket are connected by an ultrasonic puncture welding process. During the production process, the welding head of the ultrasonic welding device abuts against the bracket. The ultrasonic welding device is suitable for vibrating the abutting contact portion between the plate body and the bracket and fusing at least part of the plate body with at least part of the bracket, thereby achieving the connection and fixation of the plate body and the bracket. However, weak ultrasonic welding strength may lead to an unstable connection between the plate body and the bracket, and high ultrasonic welding strength may cause excessive transfer of heat from the mounting surface to the appearance surface, thereby causing the overall temperature of the plate body to be higher, which in turn may cause deformation and bulging of the plate body, and may also cause problems such as uneven light and shadow on the appearance surface.

[0036] In the present application, a first welding portion 12 protruding from the mounting surface is provided on the mounting surface, and a second welding portion 21 is provided on the bracket 20. At least a portion of the first welding portion 12 and the second welding portion 21 are fused together under an ultrasonic welding process. Since the connecting portion is located between the first welding portion 12 and the second welding portion 21, and the first welding portion 12 protrudes from the mounting surface, during welding, the heat generated by the welding will not be transferred to the appearance surface 11 or only a small amount will be transferred to the appearance surface 11.

[0037] At the same time, after adopting the above-mentioned setting method, during welding, the first welding part 12 and the second welding part 21 can be fused as much as possible, thereby improving the connection strength between the first welding part 12 and the second welding part 21, and further improving the connection strength between the plate body 10 and the bracket 20.

[0038] According to the exterior decorative panel 1 involved in the utility model, a first welding portion 12 protruding from the mounting surface is provided on the mounting surface, and the first welding portion 12 and the second welding portion 21 of the bracket 20 are at least partially fused to connect the plate body 10 and the bracket 20, thereby avoiding heat transfer to the appearance surface 11 during the welding process, thereby avoiding deformation and bulging of the plate body 10, and at the same time avoiding problems such as uneven light and shadow on the appearance surface 11, and during welding, the first welding portion 12 and the second welding portion 21 can be fused as much as possible, thereby improving the connection strength between the first welding portion 12 and the second welding portion 21, and further improving the connection strength between the plate body 10 and the bracket 20.

[0039] According to some embodiments of the present invention, Figure 1As shown, the second welding portion 21 is disposed on the side of the bracket 20 away from the board body 10, and the second welding portion 21 extends away from the board body 10. In some embodiments, the second welding portion 21 is formed on the side of the bracket 20 away from the board body 10, and the extension direction of the second welding portion 21 is parallel to the first welding portion 12. It can be understood that since the first welding portion 12 and the second welding portion 21 are at least partially fused to achieve the connection and fixation between the board body 10 and the bracket 20, when the second welding portion 21 extends away from the board body 10, the connection between the first welding portion 12 and the second welding portion 21 is farther from the board body 10, so that the heat energy at the connection is less likely to be transferred to the board body 10 or even the appearance surface 11, thereby further avoiding deformation and bulging of the board body 10, and at the same time, it can further avoid problems such as uneven light and shadow on the appearance surface 11.

[0040] According to some embodiments of the present invention, Figure 1 As shown, the height of the first welding portion 12 is h1, and the height of the second welding portion 21 is h2, satisfying: h1>h2.

[0041] In some embodiments, the distance between the free end of the first welding portion 12 and the mounting surface is h1, and the distance between the second welding portion 21 and the side surface of the bracket 20 facing away from the board body 10 is h2. h1>h2 can make the first welding portion 12 protrude from the second welding portion 21.

[0042] During welding, the welding head of the ultrasonic welding device first contacts the first welding part 12 and melts the first welding part 12. When the free end of the first welding part 12 is flush with the free end of the second welding part 21, the first welding part 12 and the second welding part 21 are melted together. When the first welding part 12 and the second welding part 21 are fused to a certain extent, the welding is terminated, thereby realizing the connection between the first welding part 12 and the second welding part 21.

[0043] It can be understood that the first welding portion 12 protruding from the second welding portion 21 can cause the first welding portion 12 to melt first, and after at least part of the first welding portion 12 melts, it can flow to the end surface of the second welding portion 21, so that the connection area between the first welding portion 12 and the second welding portion 21 is larger, thereby improving the connection strength between the first welding portion 12 and the second welding portion 21, and further improving the connection strength between the plate body 10 and the bracket 20.

[0044] It is worth mentioning that during the welding process, the surface of the bracket 20 facing the mounting surface and the mounting surface will vibrate with each other and generate heat, thereby achieving at least partial fusion of the surface of the bracket 20 facing the mounting surface and the mounting surface. Therefore, the above setting can make the connection stability between the bracket 20 and the plate body 10 better.

[0045] According to some embodiments of the present invention, Figure 1As shown, the height h1 of the first welding portion 12 satisfies: 5mm≤h1≤7mm. In some embodiments, the distance between the free end of the first welding portion 12 and the mounting surface satisfies 5mm≤h1≤7mm. Thus, the above arrangement can ensure good connection stability between the first welding portion 12 and the second welding portion 21 while saving materials. It is worth noting that when h1<5mm, the first welding portion 12 has fewer meltable parts, resulting in poor connection stability between the first welding portion 12 and the second welding portion 21; when h1>7mm, the first welding portion 12 has more meltable parts, but the connection stability between the first welding portion 12 and the second welding portion 21 is not significantly improved, and h1>7mm will increase the use of materials, thereby increasing the cost of the plate body 10.

[0046] According to some embodiments of the present invention, Figure 1 As shown, the height h2 of the second welding portion 21 satisfies: 2mm≤h2≤3mm. In some embodiments, the distance from the free end of the second welding portion 21 to the side surface of the bracket 20 away from the plate body 10 satisfies 2mm≤h2≤3mm. Therefore, the above-mentioned setting can ensure that the connection stability between the first welding portion 12 and the second welding portion 21 is good while preventing heat from passing through the second welding portion 21 and the bracket 20 and being transferred to the appearance surface 11. It is worth noting that when h2 is less than 2mm and after the second welding portion 21 is at least partially melted, the distance between the connection between the first welding portion 12 and the second welding portion 21 and the appearance surface 11 is relatively close, so that the heat at the connection will be transferred to the appearance surface 11; when h2 is greater than 3mm, the second welding portion 21 can melt more parts, but the connection stability between the first welding portion 12 and the second welding portion 21 is not significantly improved, and h2>3mm will increase the use of materials, thereby increasing the cost of the bracket 20.

[0047] According to some embodiments of the present invention, Figure 1 As shown, the bracket 20 is provided with a through hole 22 penetrating in the thickness direction, at least a portion of the first welding portion 12 is received in the through hole 22 , and the second welding portion 21 is provided around at least a portion of the outer circumference of the through hole 22 .

[0048] In some embodiments, a through hole 22 is provided on the bracket 20, and the second welding portion 21 is arranged around at least a portion of the periphery of the through hole 22. Before welding, the first welding portion 12 passes through the through hole 22 and protrudes from the second welding portion 21. Then, the plate body 10 and the bracket 20 are placed together on the ultrasonic welding device. At this time, the ultrasonic welding device is started and the first welding portion 12 and the second welding portion 21 are welded.

[0049] It can be understood that after at least part of the first welding portion 12 melts, it will flow to the free end of the second welding portion 21, and since the second welding portion 21 is arranged around the through hole 22 (that is, the second welding portion 21 is arranged around the first welding portion 12), at least part of the outer periphery of the first welding portion 12 is fused to the second welding portion 21, thereby, the connection between the first welding portion 12 and the second welding portion 21 is more stable, thereby improving the connection stability between the plate body 10 and the bracket 20.

[0050] According to some embodiments of the present invention, Figure 1 As shown, the thickness of the plate body 10 is s1, which satisfies: 2.5mm≤s1≤5mm, and the thickness of the first welding portion 12 is s2, which satisfies: 1mm≤s2≤1.2mm. In some embodiments, the thickness of the decorative plate satisfies 2.5mm≤s1≤5mm. At this time, the thickness of the first welding portion 12 satisfies 1mm≤s2≤1.2mm. Therefore, the thickness of the first welding portion 12 is within the above range, which can make the first welding portion 12 have a higher strength while avoiding the shrinkage of the first welding portion 12. It is worth mentioning that when s2<1mm, the strength of the first welding portion 12 is low, so that the connection strength between the first welding portion 12 and the plate body 10 is low, which makes the first welding portion 12 easy to break, and then leads to poor connection stability between the plate body 10 and the bracket 20; it can be understood that the first welding portion 12 and the plate body 10 are integrally injection molded, and when s2>1.2mm, the first welding portion 12 will shrink after molding.

[0051] According to some embodiments of the present invention, Figure 1 As shown, the hole pitch of the via 22 is w, which satisfies: 1.5mm≤w≤2mm. Therefore, through the above arrangement, after the first welding portion 12 is matched with the via 22, the spacing between the first welding portion 12 and the inner wall of the via 22 is between 0.3mm-1mm, so that it is convenient for the first welding portion 12 to pass through the via 22. It is worth mentioning that when w<1.5mm, the spacing between the inner wall of the via 22 and the first welding portion 12 is too small, which is not convenient for the first welding portion 12 to pass through the via 22, and the difficulty of matching the first welding portion 12 with the via 22 is increased; when w>2mm, the spacing between the inner wall of the via 22 and the first welding portion 12 is too large, and during welding, the first welding portion 12 and the second welding portion 21 are difficult to fuse, which increases the difficulty of connecting the bracket 20 with the plate body 10.

[0052] According to some embodiments of the present invention, Figure 1As shown, the exterior panel 1 further includes: an adhesive layer, which is arranged between the bracket 20 and the plate body 10. In some embodiments, an adhesive layer is arranged between the mounting surface and the side surface of the bracket 20 facing the plate body 10, and the adhesive layer is suitable for improving the connection stability between the bracket 20 and the plate body 10; in other embodiments, an adhesive layer is arranged between the bracket 20 and the first welding portion 12, and the adhesive layer is suitable for improving the connection stability between the bracket 20 and the first welding portion 12, thereby improving the connection stability between the bracket 20 and the plate body 10; in other embodiments, an adhesive layer is arranged between the mounting surface and the side surface of the bracket 20 facing the plate body 10, and an adhesive layer is arranged between the bracket 20 and the first welding portion 12, thereby, through the above arrangement, the connection stability between the bracket 20 and the first welding portion 12 and the plate body 10 is better, thereby improving the connection stability between the bracket 20 and the plate body 10.
