[0026] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] The present application provides a vehicle, which includes a frame and an anti-collision beam assembly. The anti-collision beam assembly is fixedly connected to the frame. The frame includes a metal bracket, a connecting plate, and fasteners. The frame plays a role of supporting, resisting mechanical shock, and resisting mechanical vibration.

[0028] It can be understood that a vehicle generally includes a front end and a rear end, the front end of the vehicle refers to an end close to the vehicle engine compartment, and the rear end of the vehicle refers to an end close to the vehicle trunk. In this example, the anti-collision beam assembly is fixedly connected to the front end of the vehicle. The connection method between the anti-collision beam assembly and the vehicle frame can be, but is not limited to, a combination of one or more of bolt connection, screw connection, rivet connection, etc.

[0029] See also Figure 1 , Figure 1 A schematic diagram of the three-dimensional structure of an anti-collision beam assembly 100 provided in one embodiment of the application. For the convenience of description, the Y axis is defined as the length direction of the anti-collision beam assembly 100, the X axis is defined as the width direction of the anti-collision beam assembly 100, and the Z axis is defined as the height direction of the anti-collision beam assembly 100. The X axis, the Y axis, and the Z axis are perpendicular to each other.

[0030] In the present application, the anti-collision beam assembly 100 includes an anti-collision beam body 10 and a protection member 20 .

[0031] The anti-collision beam body 10 is a rectangular frame structure, and the anti-collision beam body 10 includes a first peripheral wall 101, a second peripheral wall 102 and two side walls, and the two side walls are respectively a first side wall 103 and a second side wall 104. The first peripheral wall 101, the first side wall 103, the second peripheral wall 102 and the second side wall 104 are connected end to end in sequence to form the anti-collision beam body 10. Among them, the first peripheral wall 101 and the second peripheral wall 102 are opposite to each other along the Z axis direction, and the first side wall 103 and the second side wall 104 are opposite to each other along the X axis direction. The first side wall 103 and the second side wall 104 are both perpendicular to the first peripheral wall 101, and the first peripheral wall 101 and the second peripheral wall 102 are parallel to each other, so that the anti-collision beam body 10 is in a rectangular frame shape. The first peripheral wall 101 and the second peripheral wall 102, the first side wall 103 and the second side wall 104 are aligned at opposite ends along the Y axis direction.

[0032] In other examples, the cross section of the anti-collision beam body 10 in the XOZ plane is a diamond, a circle, a smoothly transitioned rectangle or other shapes, which are not limited here. When the anti-collision beam assembly 100 is fixedly installed on the vehicle frame, the first side wall 103 of the anti-collision beam body 10 is opposite to the vehicle frame, and the second side wall 104 of the anti-collision beam body 10 is opposite to the vehicle frame.

Figure 1 and Figure 3 In the embodiment, although the protective member main body 21 is not curved in a circular shape, the explanation can also be made with reference to the inner side of the curved direction of the circular shape.
