[0032] The embodiment of the present application provides a vehicle. It should be noted that the vehicle in the present application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the vehicle type, the vehicle in the present application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other vehicle types.

[0034] As competition in the new energy vehicle market becomes increasingly fierce and the cost of LiDAR is relatively high, it is necessary to reduce the number of LiDARs used to control costs. The front top crossbeam, as the highest point of the vehicle, can provide a wider field of view and a larger angle for the LiDAR. By configuring the LiDAR on the front top crossbeam, the production cost of the vehicle can be reduced. However, due to the heavy weight of the LiDAR, the requirements for the connection stiffness of the front top crossbeam are also getting higher and higher. If the thickness of the inner and outer plates of the front top crossbeam is increased, the solution cost will be higher, the weight will increase, and the lightweight of the vehicle will be affected. Therefore, the existing front top crossbeam structure has low stability when installing LiDAR.
[0035] For example, the existing crossbeam structure is directly connected to the side panel assembly 1 through a connecting piece, and the connecting piece can be a bolt structure; and the weight of the laser radar to be installed is about 5KG, and the connection stiffness of the existing crossbeam structure is low, so there is a problem of low stability when installing the laser radar.

A first connection portion 11 is provided at the end of the side enclosure component 1; a second connection portion 21 is provided at the end of the crossbeam body 2, and the second connection portion 21 is connected to the first connection portion 11; the first connection portion 11 and the second connection portion 21 are surrounded to form a first groove 4; the crossbeam body 2 is used to install a sensor device 5; the reinforcement component 3 includes a sealing plate 31, the sealing plate 31 is located at the opening of the first groove 4, and the two ends of the sealing plate 31 are respectively connected to the side enclosure component 1 and the crossbeam body 2.
[0037] The embodiment of the present application provides a crossbeam structure in which a first bend is formed at the end of the side enclosure assembly 1, so that a second connection portion 21 is formed at the end of the crossbeam body 2, and the second connection portion 21 is connected to the first connection portion 11; the first connection portion 11 and the second connection portion 21 are surrounded by a first groove 4 to increase the bending stiffness and compressive resistance of the end of the crossbeam body 2 and the end of the side enclosure assembly 1; and a sealing plate 31 is arranged at the opening of the first groove 4 so that the two ends of the sealing plate 31 are respectively connected to the first connection portion 11 and the second connection portion 21; a mating connection is formed between the first connection portion 11, the second connection portion 21 and the sealing plate 31, so that the connection strength between the crossbeam body 2 and the side enclosure assembly 1 can be improved; after the sensor device 5 is installed on the crossbeam body 2, the structural stability of the crossbeam structure can be guaranteed.

The first plate section is located between the first plate body 12 and the second plate body 13, and the inclined plate section is connected to the side of the third plate body 22 away from the first plate body 12. The addition of the inclined plate section can improve the impact resistance of the reinforcing plate 32. When the first plate section is impacted, the inclined plate section can be used to disperse the force; and the inclined plate section adapts to the end shape and structure of the third plate body 22, so that the inclined plate section and the third plate body 22 form a stable connection relationship.

The plate surface of the third body is provided with a second groove 221, and the fourth plate body 23 is used to cover the second groove 221, so that a second cavity is formed inside the second groove 221, which can ensure that the cross beam body 2 has sufficient structural strength, and at the same time can reduce the material consumption of the cross beam body 2, which is conducive to the lightweight of the vehicle and reduces the production cost. In addition, one end of the fourth plate body 23 close to the side enclosure assembly 1 extends to the plate surface of the second plate body 13 for fixed connection, which further improves the connection stability between the side enclosure assembly 1 and the cross beam body 2, and reduces the risk of abnormal noise at the connection between the side enclosure assembly 1 and the cross beam body 2. The fourth plate body 23 can be fixedly connected to the second plate body 13 by welding or riveting.
[0043] In a possible implementation of the present application, the width of the beam body 2 ranges from 600 mm to 1000 mm. Compared with the existing front beam, the width of the beam body 2 is wider, which can improve the load-bearing capacity of the beam body 2, facilitate the installation of the sensor device 5, and improve the installation stability of the sensor device 5.

Therefore, the same technical effect is achieved, and the connection strength between the beam body 2 and the side panel assembly 1 can be improved by forming a matching connection between the first connecting portion 11, the second connecting portion 21 and the sealing plate 31, thereby improving the stability of the beam body 2 after the sensor component 5 is installed. The bracket 6 is connected to the fourth plate 23 of the beam body 2 by bolts, or the bracket 6 is connected to the fourth plate 23 of the beam body 2 by welding, and the sensor component 5 is connected to the bracket 6 by bonding or clamping, which has the advantages of stable installation and simple operation.
