[0067] In order to solve the above-mentioned technical problems, the present application mainly improves the shape and material of the bracket to be connected to one side of the bumper upper part 101 and the bumper lower part 102. Specifically, please refer to the following introduction:

[0068] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 is a schematic diagram of a side view of a bumper body facing away from the front view proposed in an embodiment of the present application; Figure 2 is a front view of a bumper body proposed in one embodiment of the present application; Figure 3 It is a schematic structural diagram of a first bumper upper bracket, a second bumper upper bracket and a third bumper upper bracket proposed in an embodiment of the present application.

[0069] A bumper assembly, comprising:

[0070] A bumper body 1, wherein the bumper body 1 comprises a bumper upper portion 101 and a bumper lower portion 102;

[0071] One end of the bumper upper bracket 2 is connected to the side of the bumper upper portion 101 facing the first direction, and the other end is used to connect to the anti-collision beam 5 of the vehicle; wherein the first direction is the direction from the front of the vehicle to the rear of the vehicle;

[0072] One end of the bumper lower bracket 3 is connected to the side of the bumper lower portion 102 facing the first direction, and the other end is used to connect to the protection beam 6 of the vehicle;

[0073] The bumper upper bracket 2 and the bumper lower bracket 3 are both made of metal material, and at least one of the bumper upper brackets 2 is in a Z-shape.

[0074] The bumper upper portion 101 and the bumper lower portion 102 are integrally formed, wherein the bumper upper portion 101 and the bumper lower portion 102 enclose a frame structure having a mounting notch, wherein the mounting notch is shaped like a quadrilateral, and two corners of the mounting notch in the width direction of the vehicle body are upwardly tilted, and the length of the upper edge of the mounting notch is greater than the length of the lower edge of the mounting notch.

[0075] The bumper assembly of the present application can be applicable to the front bumper of a vehicle.

[0076] The bumper upper bracket 2 and the bumper lower bracket 3 are respectively arranged on the bumper upper portion 101 and the bumper lower portion 102 , and both face in a first direction.

[0077] In some embodiments of the present application, the first direction may also be the direction of the bumper body 1 toward the interior of the vehicle cabin.

[0078] At least one rear bumper upper bracket and at least one bumper lower bracket 3 serve to connect the bumper body 1 and the vehicle. One end of the rear bumper upper bracket is connected to the side of the bumper upper part 101 facing the first direction, and the other end is used to connect to the anti-collision beam 5 of the vehicle, ensuring that the bumper upper part 101 transmits the impact force to the anti-collision beam 5 when impacted, thereby protecting the vehicle body.

[0079] At the same time, one end of the bumper lower bracket 3 is connected to the side of the bumper lower part 102 facing the first direction, and the other end is used to connect to the vehicle's protection beam 6, ensuring that the bumper lower part 102 transmits the impact force to the protection beam 6 when impacted, thereby protecting the vehicle body.

[0080] In some embodiments of the present application, the number of the rear bumper upper bracket and the bumper lower bracket 3 can be set to multiple, and the multiple rear bumper upper brackets are distributed along the length direction of the bumper upper part 101, and the multiple bumper lower brackets 3 are distributed along the length direction of the bumper lower part 102. Among them, the length direction of the bumper upper part 101 and the length direction of the bumper lower part 102 are both the same as the width direction of the vehicle.

[0081] Through the above-mentioned arrangement, the bumper upper bracket 2 and the bumper lower bracket 3 are both made of metal materials. Compared with the prior art in which the bracket at the bumper body 1 is supported by plastic materials, the bumper upper bracket 2 and the bumper lower bracket 3 made of metal materials in the present application have higher structural strength and are not easy to bend after being impacted. At the same time, metal parts can be directly bent into shape without the need for customized molds, and cost control is better.

[0082] Secondly, the Z-shaped metal bending part has a stronger bending degree and can absorb a greater impact force when impacted. The existence of at least one bumper upper bracket 2 in a Z-shape ensures that the bumper upper part 101 has better impact resistance after impact.

[0083] In some embodiments of the present application, the bumper body 1 further includes two bumper side portions 103; wherein the two bumper side portions 103 are located on both sides of the frame structure in a second direction, and the second direction is a width direction of the vehicle;

[0143] Based on the same inventive concept, the present application also provides a vehicle, which includes a bumper assembly.

[0144] In general, this application has the following advantages:

[0145] First, the bumper upper bracket 2 and the bumper lower bracket 3 both have the function of transmitting impact and protecting the vehicle body. The bumper upper bracket 2 and the bumper lower bracket 3 are both made of metal materials. Compared with the bumper body 1 bracket in the prior art that is supported by plastic materials, the bumper upper bracket 2 and the bumper lower bracket 3 made of metal materials in this application have higher structural strength and are not easy to bend after being impacted. At the same time, the metal parts can be directly bent and formed without the need for customized molds, and the cost control is better.

[0146] Secondly, the Z-shaped metal bending part has a stronger bending degree and can absorb a greater impact force when impacted. The existence of at least one bumper upper bracket 2 in a Z-shape ensures that the bumper upper part 101 has better impact resistance after impact.

[0147] Secondly, since the vehicle is rarely subjected to side impact, the bumper side bracket 4 is made of plastic material and can use the plastic bracket matched with the existing vehicle models. On the one hand, it can effectively reduce the cost, and on the other hand, it can also reduce the weight of the vehicle to meet the requirements of lightweight vehicle.

[0148] On the third aspect, by setting the first bumper upper bracket 201, the second bumper upper bracket 202, the third bumper upper bracket 203 and the bumper lower bracket 3, the connection between the bumper upper part 101 and the bumper lower part 102 and the vehicle body is achieved, wherein the Z-shaped second bumper upper bracket 202, the third bumper upper bracket 203 and the bumper lower bracket 3 greatly increase the structural strength of the connection.

[0149] Fourthly, the positioning and fixation between the air intake grille 12 and the frame structure are achieved through the above-mentioned fixing part, the clamping part and the positioning part, and the setting of multiple structures enhances the fixing effect.

[0150] In the fifth aspect, the upper part 101 of the bumper is provided with a hook 28, which is plugged into and matched with the slot of the upper flange of the front combination lamp 13 to achieve a fixed connection in the height direction of the vehicle, and the hook 28 of the upper part 101 of the bumper is plugged into and matched with the slot of the lower flange of the front combination lamp 13 to achieve a fixed connection between the front combination lamp 13 and the upper part 101 of the bumper to prevent the front combination lamp 13 from shaking. The hook 28 of the upper part 101 of the bumper is arranged in contact with the upper flange of the front combination lamp 13 in the height direction of the vehicle, and the hook 28 of the upper part 101 of the bumper is overlapped with the lower flange of the front combination lamp 13 in the height direction of the vehicle to ensure that the gap between the front combination lamp 13 and the hook 28 is uniform.
