[0016] The left and right frames are each provided with adjustment through holes on the side near the middle frame. The left and right frames are connected to the horizontal frame by adjustment bolts, which pass through the adjustment through holes and a set of connection through holes.

[0017] Secondly, this application provides a vehicle including the bumper assembly provided in the first aspect of this application.

[0018] Compared with the prior art, the bumper assembly and vehicle provided in this application achieve at least the following beneficial effects:

[0019] The bumper assembly provided in this application is a split structure. This split structure allows for flexible disassembly and assembly based on the size and shape of different vehicle models, enabling various structural adjustments to meet diverse needs. The first type of bumper assembly includes an upper bumper structure and a lower bumper structure. The upper bumper structure comprises a left bumper section, a left split section, a middle bumper section, a right split section, and a right bumper section. This bumper assembly has a width of W1 and a height of H1. The second type of bumper assembly is derived from the first type through adjustments and modifications. Specifically, the lower bumper structure is disassembled and separated from the bottom of the left, middle, and right bumper sections, while other components remain unchanged. In this case, the vertical dimension of the bumper assembly decreases to H2, while the dimension along the vehicle width remains unchanged at W1. The third type of bumper assembly is derived from the second type through adjustments and modifications. Specifically, the left and right split sections are disassembled, and the left, middle, and right bumper sections are sequentially connected. The resulting bumper assembly has a vertical dimension of H2 and a width dimension of W2. These three bumper assemblies are compatible with three different vehicle models. Through modular design, certain components (left, right, and lower bumper structures) can be disassembled, while other components are assembled. This allows for compatibility with multiple vehicle models, avoiding the need for a separate mold for each model. Only one mold is required during the design and development of this bumper assembly, satisfying the needs of three different vehicle models and reducing mold development costs. Furthermore, when one or more components are damaged, only the damaged component needs replacement, while the undamaged components can continue to be used, reducing replacement costs and improving efficiency, thus lowering the overall maintenance cost of the bumper assembly.

[0020] Of course, any product implementing this application need not specifically need to achieve all of the technical effects described above at the same time.

[0043] Please see Figures 1 to 7This application provides a bumper assembly, including an upper bumper structure 100 and a lower bumper structure 200 located below the upper bumper structure 100. The upper bumper structure 100 includes a left bumper portion 110, a left connector portion 120, a middle bumper portion 130, a right connector portion 140, and a right bumper portion 150 that are detachably connected in sequence along the vehicle width direction. The bottom sides of the left bumper portion 110, the middle bumper portion 130, and the right bumper portion 150 are all detachably connected to the top side of the lower bumper structure 200.

[0044] The bumper assembly in this embodiment is a split structure, which can be flexibly disassembled and assembled according to the size and shape of different vehicle models, and thus adjusted into various structures to meet diverse needs. For example... Figure 1 and Figure 3 The first type of bumper assembly includes an upper bumper structure 100 and a lower bumper structure 200. The upper bumper structure 100 includes a left bumper section 110, a left split section 120, a middle bumper section 130, a right split section 140, and a right bumper section 150. The width of this bumper assembly is W1, and the height is H1. Figure 4 The second type of bumper assembly is derived from the first type through adjustments and modifications. Specifically, the lower bumper structure 200 is detached from the bottom of the left bumper section 110, the middle bumper section 130, and the right bumper section 150, while other components remain unchanged. In this case, the vertical dimension of the bumper assembly decreases to H2, while the dimension along the vehicle width remains unchanged to W1. Figure 6 The third type of bumper assembly is derived from the second type through adjustments and modifications. Specifically, the left split section 120 and the right split section 140 are disassembled, and the left bumper section 110, the middle bumper section 130, and the right bumper section 150 are connected to each other in sequence. At this time, the vertical dimension of the bumper assembly is H2, and the dimension along the vehicle width direction becomes smaller, which is W2. These three types of bumper assemblies are compatible with three different vehicle models. Through a modular design, certain components of the bumper assembly (left connector 120, right connector 140, and lower bumper structure 200) can be disassembled, while other components are assembled and connected. This allows for compatibility with multiple vehicle models, avoiding the need to design a separate mold for each model. The bumper assembly only requires one mold during design and development to meet the needs of three vehicle models, thereby reducing the development cost of bumper molds. Furthermore, when one or more of the components are damaged, only the damaged component needs to be replaced, while the undamaged components can continue to be used, thus reducing replacement costs, improving replacement efficiency, and helping to reduce the maintenance cost of the bumper assembly.

[0045] See Figure 2 , Figure 3 , Figure 5 and Figure 7 In some embodiments, the lower safety structure 200 includes a lower frame 210, the left safety part 110 includes a left frame 111, the right safety part 150 includes a right frame 151, and the middle safety part 130 includes a middle frame 131; the bottom sides of the left frame 111, the middle frame 131, and the right frame 151 are all detachably and fixedly connected to the top side of the lower frame 210. This ensures that the lower frame 210 can be reliably connected to the left safety part 110, the middle safety part 130, and the middle safety part 131.

[0046] See Figure 2 , Figure 3 , Figure 5 and Figure 7 In some embodiments, the lower bumper structure 200 also includes a lower bumper body 220, and a lower frame 210 is located on one side of the lower bumper body 220 in the direction from the front to the rear of the vehicle. The lower bumper body 220 and the lower frame 210 are connected by bolts.

[0047] The left bumper 110 also includes a left bumper body 112, and a left frame 111 is located on the side of the left bumper body 112 in the direction from the front to the rear of the vehicle. The left bumper body 112 and the left frame 111 are connected by bolts.

[0048] The right bumper 150 also includes a right bumper body 152, and a right frame 151 is located on the right bumper body 152 on one side of the vehicle from the front to the rear. The right bumper body 152 and the right frame 151 are connected by bolts.

[0049] The central safety unit 130 also includes a central grille body 132, and a central frame 131 is located on one side of the central grille body 132 in the direction from the front to the rear of the vehicle. The central grille body 132 and the central frame 131 are connected by bolts.

[0050] In this embodiment, the lower bumper body 220, the left bumper body 112, the right bumper body 152, and the right bumper body 152 can all buffer external impacts and improve the aesthetics of the bumper assembly.

[0051] Figure 8 The diagram shown is a schematic representation of the assembly connection between the central safety part, the left tap part, and the right tap part provided in an embodiment of this application. Figure 9 As shown Figure 8 A cross-sectional view of point AA in the diagram.

[0052] See Figure 3 , Figure 8 and Figure 9 In some embodiments, the central grille body 132 is provided with connecting edges 101 on both sides of the vehicle width direction, and the connecting edges 101 are located on one side of the central grille body 132 in the direction from the front to the rear of the vehicle.

[0053] The left tap 120 and the right tap 140 are provided with mounting grooves 102 on the side near the central safety part 130. The connecting edge 101 covers the mounting grooves 102, and the mounting grooves 102 are filled with adhesive tape 160.

[0054] In this embodiment, the adhesive tape 160 enables the sidewall of the mounting groove 102 to be bonded to the connecting edge 101, thereby allowing the left and right branch portions 120 and 140 to be detachably connected to both sides of the central safety part 130. This connection method is low-cost and simple to operate. The mounting groove 102 provides installation space for the adhesive tape 160, effectively reducing or even avoiding the problem of reduced adhesion caused by long-term contact and oxidation of the adhesive tape 160 with external rain and dust. Therefore, it can improve the connection stability between the left and right branch portions 120 and 140 and the central safety part 130. In actual implementation, the adhesion of the adhesive tape 160 may decrease after repeated bonding and disassembly, and the adhesive tape 160 can be replaced.

[0055] See Figure 3 In some embodiments, the central frame 131 includes two horizontal side frames 1311 arranged parallel to each other, and the two horizontal side frames 1311 are fixedly connected by two vertical connecting side frames 1312; both the vertical connecting side frames 1312 and the horizontal side frames 1311 are profile components. Thus, the central frame 131 is a frame structure, which is simple and lightweight.

[0056] Figure 10 The diagram shown is a schematic representation of an assembly connection between the horizontal border and the left frame in an embodiment of this application. Figure 11 The diagram shown is another assembly connection diagram between the horizontal frame and the left skeleton in an embodiment of this application.

[0057] See Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 10 and Figure 11 In some embodiments, each horizontal frame 1311 has two sets of connecting through holes 103 at both ends. The two sets of connecting through holes 103 are arranged along the width direction of the vehicle. In the width direction of the vehicle, the distance between the two sets of connecting through holes 103 is equal to the width of the left branch 120 and the right branch 140.

[0058] The left frame 111 and the right frame 151 are both provided with adjustment through holes 104 on the side near the middle frame 131. The left frame 111 and the right frame 151 are both connected to the horizontal frame 1311 by adjustment bolts. The adjustment bolts pass through the adjustment through holes 104 and a set of connecting through holes 103.

[0059] It should be understood that each horizontal frame 1311 has two sets of connecting through holes 103 at both ends. These two sets of connecting through holes 103 are respectively designated as the first connecting through hole 103a and the second connecting through hole 103b. The first connecting through hole 103a is closer to the end of the horizontal frame 1311 than the second connecting through hole 103b. (See also...) Figure 10 When the bumper frame is of the second type (or the first type), the adjusting bolt passes through the first connecting through hole 103a; see also Figure 11 When the bumper assembly is converted to the third structure, the adjusting bolt needs to be adjusted so that it passes through the second connecting through hole 103b. It should be noted that... Figure 11 In the embodiment shown, the left frame 111 is also provided with a connecting through hole 105, so that connecting bolts can be inserted into the connecting through hole 105 and the first connecting through hole 103a to improve the connection strength between the transverse frame 1311 and the left safety part 110; in the width direction of the vehicle, the distance between the connecting through hole 105 and the adjustment through hole 104, the spacing between the two sets of connecting through holes 103, and the width of the left branch part 120 and the right branch part 140 should all be equal.

[0060] In this embodiment, by adjusting the bolts inserted into different sets of adjustment through holes, the relative positions between the left safety part 110, the right safety part 150 and the horizontal frame 1311 can be changed, thereby allowing the total width of the middle safety part 130, the left safety part 110 and the right safety part 150 to be changed.
