[0003] Pedestrian protection is a very important safety measure, which is of great significance for protecting the lives of pedestrians, reducing the casualties of traffic accidents, and improving the safety performance of automobiles.

[0040] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0041] Terminology explanation:

[0042] Shotgun structure: refers specifically to the upper longitudinal beam, also known as the reinforcement structure of the front longitudinal beam. It is located between the A-pillar and the headlight beam, carrying the key force transmission task, and is an important part of the front structure of the car; it is the core component of the vehicle's front collision safety system, mainly used to strengthen the front structure and optimize the energy transfer path during a collision.

[0043] Embodiment 1

[0044] As introduced in the background technology, existing new energy vehicles cannot take into account both the height of the engine hood 51 and the vehicle-pedestrian protection performance. In order to solve the above technical problems, this embodiment proposes an upper longitudinal beam structure assembly, which is beneficial to the deformation of the engine hood 51 by optimizing the structural design, thereby reducing the damage value to pedestrians during collision.

[0045] Combination Figure 1-Figure 8 The upper longitudinal beam structure assembly includes a front longitudinal beam wheel house connecting beam assembly 11, a front wheel house upper reinforcement beam outer plate front assembly 12 and a front wheel house upper reinforcement beam outer plate rear assembly 13 which are sequentially connected along the longitudinal direction of the engine cover 51; the front longitudinal beam wheel house connecting beam assembly 11 is welded to the bottom of the front wheel house upper reinforcement beam outer plate front assembly 12, and is located at one end of the front wheel house upper reinforcement beam outer plate front assembly 12 along the length direction, and forms an angle with the front wheel house upper reinforcement beam outer plate front assembly 12; the front wheel house upper reinforcement beam outer plate front assembly 12 is overlapped on the cast aluminum shock absorber tower 55, and the upper surface of the front wheel house upper reinforcement beam outer plate front assembly 12 is flush with the highest point of the cast aluminum shock absorber tower 55; the front wheel house upper reinforcement beam outer plate rear assembly 13 is connected to the other end of the front wheel house upper reinforcement beam outer plate front assembly 12 along the length direction by bolts, and is arranged opposite to the front longitudinal beam wheel house connecting beam assembly 11.

[0046] Further, such as Figure 1 , 2 As shown, the front longitudinal beam wheel cover connecting beam assembly 11 includes a front longitudinal beam wheel cover connecting beam body, an upper cover plate 21 and an outer plate 24. The front longitudinal beam wheel cover connecting beam body is composed of a front longitudinal beam wheel cover connecting beam inner plate upper section 22 and a front longitudinal beam wheel cover connecting beam inner plate lower section 23 connected to each other. The front longitudinal beam wheel cover connecting beam inner plate lower section 23 is bent backward. The middle part of the front longitudinal beam wheel cover connecting beam body is recessed inward to form a groove, and a flange is formed at the edge. The outer plate 24 is welded to one side (opening side) of the front longitudinal beam wheel cover connecting beam body. The outer plate 24 and the front longitudinal beam wheel cover connecting beam body form a square cavity, providing a welding position for the fender front mounting bracket 25. The upper cover plate 21 is welded above the front longitudinal beam wheel cover connecting beam body and the outer plate 24. The other side (non-opening side) of the front longitudinal beam wheel cover connecting beam body is welded with the fender front mounting bracket 25 assembly.

[0047] The fender front mounting bracket 25 assembly includes a fender front connecting plate 26, a fender front mounting bracket 25 and a fender bracket reinforcement plate 27. One side of the fender bracket reinforcement plate 27 is a U-shaped structure that matches the non-opening side of the front longitudinal beam wheel cover connecting beam body and is welded to the front longitudinal beam wheel cover connecting beam body; the other side of the fender bracket reinforcement plate 27 has a plate-like protrusion, one side of the fender front connecting plate 26 has a recess that matches the plate-like protrusion, the fender front connecting plate 26 is installed on the other side of the fender bracket reinforcement plate 27, and the fender front connecting plate 26 and the fender bracket reinforcement plate 27 are connected. A U-shaped structure is formed, with the middle part concave inward, the flange at the lower edge welded to the fender bracket reinforcement plate 27, and the upper outer flange is welded to the fender front mounting bracket 25 and the fender bracket reinforcement plate 27 in three layers; the fender front mounting bracket 25 is an L-shaped cantilever structure, the vertical part of which is welded to the top end flange of the fender front connecting plate 26, and the horizontal part overlaps with the front outer panel front assembly 12 of the reinforcing beam on the front wheel cover, and the height is lower than the front outer panel front assembly 12 of the reinforcing beam on the front wheel cover, thereby increasing the deformation space of the engine cover 51 in the Z direction, and the L-shaped cantilever structure is conducive to compression and bending deformation, reducing head injuries.

[0048] For example, the specific effects are as follows Figure 6 As shown, the bracket has a cantilever structure, which will flip and deform during a collision to reduce head injuries.

[0049] like Figure 1 , Figure 3 As shown, the front wheel housing upper reinforcement beam outer panel front assembly 12 includes a front wheel housing upper reinforcement beam outer panel front body 31, a buffer block bracket 32, a fender middle bracket 33 and a fender rear bracket 34. The front wheel housing upper reinforcement beam outer panel front body 31 is welded above the upper cover plate 21. The front wheel housing upper reinforcement beam outer panel front body 31 is an L-shaped structure, the outer side of its horizontal portion overlaps with the cast aluminum shock absorber tower 55, and the bottom of its vertical portion is connected with a horizontal flange and overlaps with the L-shaped flange of the cast aluminum shock absorber tower 55. A square cavity is formed; installation space for a buffer block bracket 32, a fender middle bracket 33 and a fender rear bracket 34 is formed between the horizontal flange and the vertical portion; the buffer block bracket 32, the fender middle bracket 33 and the fender rear bracket 34 are installed on the vertical portion of the front body 31 of the outer plate of the reinforcing beam on the front wheel cover at intervals in sequence along the length direction; and the height of the buffer block bracket 32, the fender middle bracket 33 and the fender rear bracket 34 is lower than the upper surface of the front body 31 of the outer plate of the reinforcing beam on the front wheel cover, thereby increasing the Z-direction deformation space of the engine cover 51.

[0050] At the same time, the upper surface height of the outer plate 24 of the reinforcing beam on the front wheel housing is flush with the cast aluminum shock tower 55, and no additional bracket is arranged on it, thereby increasing the collision deformation space of the engine cover 51.

[0051] Specifically, the buffer block bracket 32 ​​is an L-shaped structure composed of a vertical plate and a horizontal plate, and is connected to the front body 31 of the outer plate of the reinforcing beam on the front wheel cover through the vertical plate. Through simulation calculation, it can meet the strength requirements of the buffer block 52 while deforming in time when the engine cover 51 collides; the fender middle bracket 33 is a U-shaped structure, and the fender rear bracket 34 is a U-shaped structure. The U-shaped structure is composed of a first vertical plate, a first horizontal plate, a second vertical plate and a second horizontal plate connected end to end in sequence; different from the traditional L-shaped structure, the middle position of the U-shaped structure is suspended. When the engine cover 51 is deformed downward due to a collision, the bracket can effectively avoid the side wall structure of the engine cover 51, thereby increasing the space for the engine cover 51 to deform downward. The U-shaped structure has more bending points and is more likely to be crushed and deformed, so that the engine cover 51 is more likely to deform, reducing pedestrian head injuries; and the middle position between the fender middle bracket 33 and the fender rear bracket 34 provides a layout space for the gas spring 53, which can be arranged on the side of the shotgun, thereby increasing the deformation space between the engine cover 51 and the shotgun; the specific effects are as follows: Figure 7 shown.

[0052] The front body of the reinforcement beam outer plate 24 is formed by stamping a metal sheet, and the material is high-strength steel. The upper surface is closely designed to follow the cast aluminum shock tower 55. The height of the reinforcement rib does not exceed 3mm, the minimum Z-direction section height is only 27mm, and the average section height is about 30mm. By compressing the Z-direction section height to the extreme, the collision deformation space between the surface of the engine cover 51 and the shotgun is increased. Due to the low Z-direction height, there is insufficient space for the projection welding of the side nuts, and the rivet nuts are used to provide installation points for the side brackets. The front body of the reinforcement beam outer plate 24 is connected to the shock tower by SPR (self-piercing riveting).

[0053] Further, such as Figure 1 , Figure 4As shown, the front wheel housing upper reinforcement beam outer plate rear assembly 13 includes a front wheel housing upper reinforcement beam outer plate rear body 42, one end of the front wheel housing upper reinforcement beam outer plate rear body 42 along the length direction is connected to a gas spring mounting bracket 43, and one end of the front wheel housing upper reinforcement beam outer plate rear body 42 along the width direction is connected to a hinge mounting bracket 41 through a Y-direction bolt, and then the hinge 54 is arranged on the side of the shotgun structure to increase the deformation space between the engine cover 51 and the shotgun structure; the front wheel housing upper reinforcement beam outer plate rear body 4 2 comprises a first horizontal portion, a first vertical portion and a second horizontal portion connected in sequence to form a U-shaped structure; a groove structure is provided on the first vertical portion, a hinge mounting bracket 41 is located in the middle of the groove structure, one side of the gas spring mounting bracket 43 is mounted on the end of the rear body 42 of the outer plate of the reinforcing beam on the front wheel cover, and the other side is mounted on the end of the front body 31 of the outer plate of the reinforcing beam on the front wheel cover; the Z-direction arrangement height of the hinge 54 is reduced, the hinge 54 is farther away from the outer cover, and when the hinge 54 is hit, more Z-direction deformation space can be provided.

[0054] When in use, the front longitudinal beam wheelhouse connecting beam assembly 11 is connected to the engine compartment longitudinal beam, the front wheelhouse upper reinforcing beam outer plate front assembly 12 is overlapped with the flange of the cast aluminum shock absorber tower 55, and the front wheelhouse upper reinforcing beam outer plate rear assembly 13 is connected to the A-pillar of the vehicle body.
