[0065] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0066] Example

[0067] Figure 1 This is a front view of vehicle 1 in one embodiment of this application; Figure 2 for Figure 1 A partial structural schematic diagram of the bumper assembly 100 in the illustrated embodiment.

[0068] See Figure 1 This application provides a vehicle 1, including a bumper assembly 100.

[0069] Please continue reading. Figure 2 The bumper assembly 100 includes a bumper 10, which is an exterior trim piece of the vehicle 1 and is used to absorb and mitigate external impacts and protect the front and rear of the vehicle 1. In this embodiment, the bumper 10 is a front bumper and is located on the front side of the vehicle 1.

[0070] Figure 3 for Figure 1 An exploded view of a portion of the bumper assembly 100 in the illustrated embodiment; Figure 4 for Figure 1 Partial structural cross-sectional view of the bumper assembly 100 in the illustrated embodiment; Figure 5 for Figure 1 A schematic diagram of the assembly state of the lampshade 20, the fixing bracket 40, and the welding bracket 50 in the embodiment shown.

[0071] See Figures 2 to 4 This embodiment provides a bumper assembly 100, including a bumper 10, a lampshade 20, and a reinforcing structure 30. The bumper 10 has a light-transmitting hole 10a and an edge portion 11 surrounding the light-transmitting hole 10a. The lampshade 20 is disposed on one side of the bumper 10. Figure 5 As shown, the lampshade 20 includes a light-transmitting part 21 and a blocking part 22. The light-transmitting part 21 cooperates with the light-transmitting hole 10a, and the blocking part 22 is connected to the light-transmitting part 21 and is located inside the edge part 11. The reinforcing structure 30 is provided inside the lampshade 20 and is supported by the blocking part 22.

[0072] The aforementioned bumper assembly 100 allows light from the lampshade 20 to pass through a light-transmitting hole 10a provided on the bumper 10. A reinforcing structure 30 is provided, which supports the shielding portion 22 located on the edge portion 11 near the lampshade 20. This allows the reinforcing structure 30 to provide support for the shielding portion 22, thereby supporting the outer edge portion 11 of the shielding portion 22, thus improving the impact strength and paint adhesion of the bumper assembly 100 at the edge portion 11.

[0073] It should be noted that "inner side" refers to the side facing inside the vehicle 1, and "outer side" refers to the side facing outside the vehicle 1. For a single light-transmitting hole 10a, the edge portion 11 of the light-transmitting hole 10a has an annular structure, the inner periphery of the edge portion 11 is the edge of the light-transmitting hole 10a, and the shape of the outer periphery of the edge portion 11 corresponds to the shape of the light-transmitting hole 10a. Optionally, there are multiple light-transmitting holes 10a, which are spaced apart on the bumper 10. The edge portion 11 includes an annular structure and a middle structure. The annular structure is located on the outer periphery of the multiple light-transmitting holes 10a, and the middle structure is connected to the inner periphery of the annular structure and is located between adjacent light-transmitting holes 10a. In this embodiment, there are 6 light-transmitting holes 10a.

[0074] Optionally, the light-transmitting hole 10a can be a logo hole, allowing light transmitted through the lampshade 20 to display the logo on the bumper 10. It should be noted that in related technologies, the logo hole is usually irregularly shaped. Since the bumper is made of plastic, processing the light-transmitting hole using laser cutting or ultrasonic punching processes can easily lead to significant deformation due to the bumper's high toughness, thus affecting the impact strength and surface quality of the edges. In the above embodiment, by providing support and cushioning for the lampshade 20 with the reinforcing structure 30, the impact strength of the bumper assembly 100 can be improved and the risk of paint chipping can be reduced.

[0075] Figure 6 for Figure 1 A schematic diagram of the assembly state of the reinforcing structure 30, the welding bracket 50, and the fixing bracket 40 in the embodiment shown.

[0076] In some embodiments, such as Figure 3 and Figure 4 As shown, the bumper assembly 100 also includes a fixing bracket 40 connected to the bumper 10. The fixing bracket 40 is supported on the inner side of the lamp cover 20, defining a receiving space 100a between the fixing bracket 40 and the lamp cover 20. A reinforcing structure 30 is disposed within the receiving space 100a and supported between the fixing bracket 40 and the shielding portion 22. Thus, by providing the fixing bracket 40, the reinforcing structure 30 is supported between the lamp cover 20 and the fixing bracket 40, ensuring that the reinforcing structure 30 can provide reliable support for the bumper 10. Optionally, combined with Figure 6 As shown, the side of the reinforcing structure 30 furthest from the bumper 10 is snapped into connection with the fixed bracket 40. The edge of the lampshade 20 is provided with a rubber band. During installation, vibration friction is used to melt the rubber band, so that the lampshade 20 and the fixed bracket 40 are connected by vibration friction welding.

[0077] Figure 7 for Figure 1 A partial structural schematic diagram of the bumper assembly 100 in the illustrated embodiment from another perspective.

[0078] In some embodiments, such as Figure 3 and Figure 7 As shown, the bumper assembly 100 also includes a welding bracket 50, which has a welding portion 51 and a mounting post 52. The welding portion 51 is welded to the bumper 10, and the fixing bracket 40 is connected to the mounting post 52 via a locking member 60. Thus, the fixing bracket 40 is connected to the bumper 10 via the welding bracket 50 on the side closest to the bumper 10, forming a stable connection between the bumper 10, the welding bracket 50, and the fixing bracket 40, thereby improving the reliability of the reinforcement structure 30 in supporting the bumper 10. Optionally, the welding portion 51 is connected to the bumper 10 by ultrasonic welding.

[0079] In some embodiments, such as Figure 3 As shown, there are multiple welding parts 51, which are spaced apart from each other along the outer periphery of the welding bracket 50 to improve the reliability of the welding connection between the welding bracket 50 and the bumper 10. In this embodiment, there are 6 welding parts 51.

[0080] In some embodiments, there are multiple mounting posts 52 and multiple locking elements 60, and the multiple mounting posts 52 and multiple locking elements 60 are arranged in a one-to-one correspondence. The multiple mounting posts 52 are spaced apart from each other along the outer periphery of the welding bracket 50 to improve the connection reliability between the welding bracket 50 and the fixed bracket 40. In this embodiment, there are three mounting posts 52 and three locking elements 60.

[0081] In some embodiments, such as Figure 7 As shown, the fixed bracket 40 is provided with positioning holes 40a, and the welding bracket 50 is also provided with positioning ribs 53. The positioning ribs 53 are correspondingly inserted through the positioning holes 40a to position the welding bracket 50 relative to the fixed bracket 40. Optionally, the positioning ribs 53 can be cross-shaped positioning ribs. There are multiple positioning holes 40a and multiple positioning ribs 53, and the multiple positioning holes 40a and multiple positioning ribs 53 are arranged in a one-to-one correspondence. Multiple mounting posts 52 are arranged at intervals along the outer periphery of the welding bracket 50. In this embodiment, there are three positioning holes 40a and three positioning ribs 53.

[0082] In some embodiments, the thickness of the portion of the bumper 10 near the light-transmitting hole 10a is greater than the thickness of other portions of the bumper 10 to improve the impact strength and welding quality of the portion of the bumper 10 near the light-transmitting hole 10a. Optionally, the thickness of the portion of the bumper 10 near the light-transmitting hole 10a is greater than or equal to 3.2 mm and less than or equal to 3.5 mm, while the thickness of other portions of the bumper 10 is 2.5 mm.

[0083] In the actual assembly process of the aforementioned bumper assembly 100, the reinforcing structure 30 is first snapped together with the fixed bracket 40, and then the edge of the lamp cover 20 is vibrated and friction-welded to the fixed bracket 40. The welding bracket 50 is then fixed to the inner surface of the bumper 10 by ultrasonic welding, and the fixed bracket 40 is then fixed to the welding bracket 50 by the locking member 60, with the positioning rib 53 positioning the fixed bracket 40 relative to the welding bracket 50.

[0084] Figure 8 This is a schematic diagram of the processing apparatus 200 in one embodiment of this application; Figure 9 for Figure 8 A schematic diagram of the assembly state of the processing device 200 and the bumper 10 in the embodiment shown.

[0085] See Figure 8 and Figure 9 According to another aspect of this application, a processing apparatus 200 is provided for processing the bumper assembly 100 as described in any of the above embodiments. The processing apparatus 200 includes a worktable 210 and a laser cutting mechanism (not shown in the figure). The worktable 210 is used to support the bumper 10, and the laser cutting mechanism is used to cut light-transmitting holes 10a on the bumper 10 to adapt to the shape requirements of the light-transmitting holes 10a, for example, to process light-transmitting holes 10a with irregular shapes.

[0086] In some embodiments, the laser cutting mechanism includes a laser head (not shown). During use, the bumper 10 is placed on the worktable 210, and the laser head cuts the bumper 10. The laser head angle is adjusted during the cutting process to cut along the normal direction of the bumper 10's shaped surface. Furthermore, the cutting process parameters of the laser cutting mechanism can be adjusted and optimized to improve the cutting quality of the bumper 10, for example, avoiding quality problems such as burrs, jagged edges, or scorching at the edges of the light-transmitting hole 10a. The cutting process parameters include laser power, cutting speed, cutting gas pressure, and the cutting height of the laser head. In this embodiment, the laser power of the laser cutting mechanism is 250 watts, the cutting speed is greater than or equal to 15 mm / s and less than or equal to 20 mm / s, the cutting gas pressure is greater than or equal to 0.65 MPa and less than or equal to 0.75 MPa, and the cutting height is greater than or equal to 4 mm and less than or equal to 6 mm.

[0087] Figure 10 for Figure 8 A schematic diagram of the feeding mechanism 230 in the illustrated embodiment; Figure 11 for Figure 8 A schematic diagram of the assembly state of the feeding mechanism 230 and the welding bracket 50 in the embodiment shown.

[0088] In some embodiments, such as Figure 10 and Figure 11 As shown, the bumper assembly 100 also includes a welding bracket 50, which has a welding portion 51. The processing device 200 also includes a feeding mechanism 230, which is used to fix the welding bracket 50 and drive the welding bracket 50 toward the bumper 10 (see...). Figure 9 The feed mechanism 230 moves to one side so that the welding part 51 contacts the bumper 10. In this way, by setting the feed mechanism 230, it is beneficial to improve the relative positional accuracy of the welding bracket 50 and the bumper 10, thereby improving the relative positional accuracy of the lampshade 20 and the bumper 10, so that the gap between the light-transmitting part 21 of the lampshade 20 and the edge of the light-transmitting hole 10a is uniform.

[0089] Optionally, such as Figure 10 As shown, the feeding mechanism 230 is provided with positioning grooves 230a for positioning the welding bracket 50, so that the welding bracket 50 is fixed relative to the feeding mechanism 230. In this embodiment, there are 3 positioning grooves 230a.

[0090] In some embodiments, such as Figure 10 and Figure 11 As shown, the feeding mechanism 230 includes a supporting part 231 and a positioning part 232. The supporting part 231 is used to support the welding bracket 50. The positioning part 232 protrudes from the supporting part 231 and can pass through the light-transmitting hole 10a (see...). Figure 9 The feeding mechanism 230 is positioned relative to the light-transmitting hole 10a to ensure precise positioning of the welding bracket 50 and the bumper 10. This improves the welding accuracy of the welding bracket 50 and the bumper 10, thereby increasing the installation accuracy of the lampshade 20 and the bumper 10, and ensuring a uniform gap between the light-transmitting part 21 and the edge of the light-transmitting hole 10a after the lampshade 20 is installed. Optionally, the feeding mechanism 230 also includes a driving component 233 (such as a cylinder) for driving the bearing part 231.

[0091] In some embodiments, combined with Figure 10 and Figure 11 As shown, the processing device 200 also includes a welding mechanism 240, which is located outside the feeding mechanism 230 and is used to weld the welding part 51 to the bumper 10 (see Figure 10). Figure 9Optionally, the welding mechanism 240 includes multiple ultrasonic welding heads, each corresponding to a multiple welding part 51, and the ultrasonic welding heads are used to weld the corresponding welding part 51 to the bumper 10.

[0092] Figure 12 for Figure 8 A partial structural schematic diagram of the processing apparatus 200 in the illustrated embodiment.

[0093] In some embodiments, such as Figure 12 As shown, the processing device 200 also includes a support member 250 and a clamping member 260. Along the axial direction of the light-transmitting hole 10a, the support member 250 and the clamping member 260 are respectively disposed on the bumper 10 (see...). Figure 9 The two sides of the bumper 10 are pressed between the support member 250 and the clamping member 260 to increase the laser cutting intensity of the part of the bumper 10 near the light-transmitting hole 10a, thereby ensuring that the bumper 10 can be effectively cut.

[0094] In some embodiments, such as Figure 12 As shown, the processing device 200 also includes an adsorption element 270, which is used to adsorb the bumper 10 (see...). Figure 9 This fixes the bumper 10 relative to the worktable 210, thereby further improving the laser cutting intensity of the portion of the bumper 10 near the light-transmitting hole 10a and preventing deformation of the bumper 10 from affecting the cutting quality of the light-transmitting hole 10a. Optionally, the suction component 270 can be a vacuum suction cup. In this embodiment, the vacuum pressure of the vacuum suction cup is 0.6 MPa.

[0095] In some embodiments, such as Figure 9 As shown, the bumper 10 is provided with a bumper positioning hole 10b, and the worktable 210 is provided with a positioning component 280. The positioning component 280 cooperates with the bumper positioning hole 10b to position the bumper 10 relative to the worktable 210, thereby improving the relative positional accuracy between the bumper 10 and the worktable 210, and further improving the positional accuracy of the light-transmitting hole 10a, as well as the consistency of multiple cuts of the light-transmitting hole 10a.

[0096] During processing, the aforementioned processing device 200 first places the welding bracket 50 on the feeding mechanism 230 and positions it relative to the feeding mechanism 230 using the positioning groove 230a. Then, the bumper 10 is placed on the worktable 210 and positioned relative to the worktable 210 using the bumper positioning hole 10b and the positioning member 280. Next, the bumper 10 is pressed together by the support member 250 and the clamping member 260, and the bumper 10 is fixed by the adsorption member 270 to ensure the laser cutting intensity of the bumper 10. Then, the laser cutting mechanism cuts a light-transmitting hole 10a into the bumper 10. After cutting, the driving member 233 drives the feeding mechanism 230 to approach the bumper 10, bringing the welding part 51 into contact with the bumper 10. Finally, the welding mechanism 240 welds the welding part 51 to the bumper 10.

[0097] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
