In addition, the existing side beam assembly, limited by its own structure, has the problem of poor force transmission when the vehicle collides with the front, which is not conducive to ensuring the force transmission effect of the front end of the vehicle and the safety performance of the vehicle.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] Embodiment 1

[0044] This embodiment relates to a vehicle body front end structure, the overall structure is as follows: Figure 1 As shown in , the front end structure of the vehicle body includes a side beam assembly, which includes a side beam body, and the side beam body includes a first beam body 1 and a second beam body 2 arranged at the rear end of the first beam body 1. The first beam body 1 is bent and has a transverse portion 101 extending along the front-to-rear direction of the vehicle, and an inclined portion 102 extending to the rear and lower part of the transverse portion 101, and the inclined portion 102 is connected to the sill beam 3. The second beam body 2 extends along the front-to-rear direction of the vehicle, and the second beam body 2 is connected to the rear end of the transverse portion 101 and is connected to the A-pillar 4.

[0045] In this embodiment, the first beam body 1 is bent and has a transverse portion 101 and an inclined portion 102, and the inclined portion 102 is connected to the sill beam 3, and the second beam body 2 connected to the rear end of the transverse portion 101 is connected to the A-pillar 4. Compared with the connection between the cabin side beam and the A-pillar 4 of the traditional vehicle model, the force during a frontal collision is transmitted from the cabin side beam to the A-pillar 4, and then from the A-pillar 4 to the sill beam 3 in a "Z"-shaped force transmission path. In this embodiment, the collision force during a frontal collision can be directly transmitted to the sill beam 3 via the first beam body 1, and the front collision force transmission channel is smooth, which is conducive to improving the transmission effect of the collision force and the safety of the cab.

[0046] Based on the above overall introduction, as a preferred implementation method, Figure 2 and Figure 3 As shown in , in this embodiment, the side beam assembly includes a front connecting beam 5 and a rear connecting beam 6 arranged on the side beam body close to the vehicle interior. The front connecting beam 5 and the rear connecting beam 6 are arranged at intervals along the front and rear direction of the vehicle, and the front connecting beam 5 and the rear connecting beam 6 are both bent and connected to the side beam body and the cabin longitudinal beam 7 to form an installation space, and the installation space is used to install the shock tower 8.

[0047] It is understandable that by connecting the front connecting beam 5 and the rear connecting beam 6 between the side beam body and the cabin longitudinal beam 7, an installation space can be formed, which is convenient for installing the shock tower 8, and is conducive to improving the structural strength of the front end of the vehicle body, and is convenient for the collision force transmitted to the cabin longitudinal beam 7 to be transmitted to the side beam body through the front connecting beam 5 and the rear connecting beam 6. In addition, by making the front connecting beam 5 and the rear connecting beam 6 in a bent shape, it is convenient to connect the front connecting beam 5 and the rear connecting beam 6 with the side beam body and the cabin longitudinal beam 7, and it is conducive to making the front connecting beam 5 and the rear connecting beam 6 have better structural strength.

[0048] In specific implementation, as preferred, Figure 2 and Figure 3 As shown in , in this embodiment, the front connecting beam 5 and the rear connecting beam 6 are both in an inverted "L" shape, and include a first portion extending in the left-right direction of the vehicle, and a second portion extending below the first portion. The first portion is connected to the side beam body, and the second portion is connected to the cabin longitudinal beam 7. By making the front connecting beam 5 and the rear connecting beam 6 both in an inverted "L" shape, it is convenient to connect the front connecting beam 5 and the rear connecting beam 6 with the side beam body and the cabin longitudinal beam 7, and it is also beneficial for the front connecting beam 5 and the rear connecting beam 6 to adapt to the shape of the side walls on the front and rear sides of the shock tower 8, so that the front connecting beam 5 and the rear connecting beam 6 have a larger contact area with the shock tower 8, which is convenient for ensuring the connection strength between the front connecting beam 5 and the rear connecting beam 6 and the shock tower 8.

[0049] It should be noted that the above-mentioned components, such as the front connecting beam 5 and the rear connecting beam 6 and the side beam body and the cabin longitudinal beam 7, and the front connecting beam 5 and the rear connecting beam 6 and the shock tower 8 can be connected by fusion welding. In addition, in this embodiment, the front connecting beam 5 and the rear connecting beam 6 are both in an inverted "L" shape, which is only used as a preferred implementation method. In other embodiments, the front connecting beam 5 or the rear connecting beam 6 can also be selected to be in other bending shapes, such as the front connecting beam 5 or the rear connecting beam 6 can be in a "V" shape, etc., to facilitate the connection between the front connecting beam 5 or the rear connecting beam 6 and the shock tower 8, and to facilitate the connection between the front connecting beam 5 and the rear connecting beam 6 and the side beam body and the cabin longitudinal beam 7.

[0050] As a preferred implementation, in this embodiment, the side beam assembly includes a connecting structure disposed at the front end of the front connecting beam 5, and the connecting structure is connected to the front frame. This arrangement facilitates the transmission of the collision force at the front end of the vehicle to the front connecting beam 5 through the front frame and the connecting structure, which is beneficial to increasing the force transmission channel and improving the smoothness of the transmission of the collision force. In addition, the connecting structure and the front frame can also be connected by a fusion welding method commonly used in the prior art.

[0051] In specific implementation, as preferred, Figure 2As shown in , the connection structure includes a first connection beam 9 and a second connection beam 10 arranged in front of the front connection beam 5. The first connection beam 9 extends upward in the up-down direction of the whole vehicle, and the second connection beam 10 is connected between the first connection beam 9 and the front connection beam 5. By making the connection structure include the first connection beam 9 and the second connection beam 10, the structure is simple and easy to arrange. At the same time, the first connection beam 9 extends up and down in the up-down direction of the whole vehicle, and the second connection beam 10 is connected between the first connection beam 9 and the front connection beam 5. The first connection beam 9, the second connection beam 10, the front connection beam 5 and the cabin longitudinal beam 7 can be surrounded to form a ring structure with good structural strength and force transmission effect.

[0052] As a preferred implementation method, Figure 2 As shown in the figure, in this embodiment, the connection structure includes a third connection beam 11 provided on the side of the first connection beam 9 close to the vehicle interior, and the third connection beam 11 extends in the left-right direction of the vehicle. By providing the third connection beam 11 on the side of the first connection beam 9 close to the vehicle interior, it is convenient to connect the connection structure with the front end frame, and the structure is simple and the layout is convenient.

[0053] Of course, in this embodiment, the connection structure includes the first connection beam 9, the second connection beam 10 and the third connection beam 11, which is only a preferred implementation. In addition, the connection structure can also be set in other forms, such as not setting the first connection beam 9. In this case, the third connection beam 11 can be connected to the second connection beam 10, and the connection between the front frame and the front connection beam 5 can also be achieved. In addition, the connection structure can also be a bent connection beam directly connected between the front connection beam 5 and the front frame, so that the collision force on the front frame can be transmitted to the front connection beam 5 via the connection beam.

[0054] As a preferred example, Figure 1 As shown in , in this embodiment, the side beam assembly includes a vertical beam 12 and a cross beam 13 arranged at the rear end of the second beam body 2. The vertical beam 12 is connected to the top of the second beam body 2, and the cross beam 13 is connected between the vertical beam 12 and the A-pillar 4.

[0055] It can be understood that by providing a vertical beam 12 at the rear end of the second beam body 2 and a cross beam 13 connected between the vertical beam 12 and the A-pillar 4, the cross beam 13, the vertical beam 12, the second beam body 2 and the A-pillar 4 form a ring structure, which is beneficial to improving the structural strength of the connection position between the second beam body 13 and the A-pillar 4, and the collision force can be transmitted to the A-pillar 4 via the second beam body 2, the vertical beam 12 and the cross beam 13, thereby increasing the force transmission channel between the second beam body 2 and the A-pillar 4, which is beneficial to improving the transmission effect of the collision force.

[0056] As a preferred implementation method, Figure 1As shown in , in this embodiment, a reinforcing beam 14 is provided below the second beam body 2 corresponding to the vertical beam 12. The reinforcing beam 14 is arranged at an angle with the second beam body 2 and connected between the second beam body 2 and the A-pillar 4. The reinforcing beam 14 is connected between the second beam body 2 and the A-pillar 4, which is beneficial to improving the structural strength of the connection position between the second beam body 2 and the A-pillar 4. At the same time, the collision force transmitted to the second beam body 2 can also be transmitted to the A-pillar 4 via the reinforcing beam 14, thereby further increasing the force transmission channel between the second beam body 2 and the A-pillar 4, and improving the transmission effect of the collision force of the front end of the vehicle body.

[0057] In the specific implementation, as a preferred embodiment, the side beam assembly can be welded by pipe beams, so that the process is simple, the precision is easy to ensure, and because there is no mold investment, the production cost is low, which is suitable for the development of small batch models. In addition, the pipe beams that make up the side beam assembly can be connected by fusion welding, which is simple to operate and has a firm connection.

[0058] The front end structure of the vehicle body of this embodiment is to make the first beam body 1 have a transverse portion 101 and an inclined portion 102, and make the inclined portion 102 connected to the sill beam 3, so that the second beam body 2 connected to the rear end of the transverse portion 101 is connected to the A-pillar 4, so that the collision force is conveniently transmitted to the sill beam 3 and the A-pillar 4 during a front collision, and the front collision force transmission channel is smooth, which is conducive to improving the transmission effect of the collision force and the safety of the cab. In addition, by providing a connection structure, connecting the front connecting beam 5 and the rear connecting beam 6 between the side beam body and the cabin longitudinal beam 7, and connecting the vertical beam 12, the horizontal beam 13 and the reinforcing beam 14 between the second beam body 2 and the A-pillar 4, it is conducive to meeting the bending and torsional stiffness, modal, and offset collision requirements of the whole vehicle.
