[0028] With the increasing popularity of automobiles, people have higher requirements for vehicle safety performance. Vehicles will face various unexpected situations on the road during operation. How to minimize harm to pedestrians and vehicle occupants in the event of such emergencies remains a pressing issue.

[0029] To address the related technical problems, this application provides a vehicle that includes the following vehicle front-end assembly.

[0030] To address the related technical issues, this application also provides a vehicle front-end assembly, for details please refer to [link / reference needed]. Figure 1 , Figure 1 This is a first-view structural schematic diagram of an embodiment of the vehicle front-end assembly provided in this application.

[0031] The vehicle front end assembly 10 includes a front bulkhead 100 and a windshield crossbeam assembly 200. The windshield crossbeam assembly 200 includes an upper windshield crossbeam 210 and a lower windshield crossbeam 220. The lower windshield crossbeam 220 is connected to one side of the front bulkhead 100 and extends in a direction away from the front bulkhead 100. The upper windshield crossbeam 210 is connected to the side of the lower windshield crossbeam 220 away from the front bulkhead 100. The upper windshield crossbeam 210 and the front bulkhead 100 are spaced apart in the extension direction X of the lower windshield crossbeam 220 to form a protective area 300 between the upper windshield crossbeam 210 and the lower windshield crossbeam 220.

[0032] The front bulkhead 100 is erected, with the engine compartment and passenger compartment on its two sides, respectively, separating the two compartments and protecting the occupants inside. An A-pillar can be connected to each end of the front bulkhead 100 to improve the collision performance of the vehicle's front-end assembly 10.

[0033] The windshield crossbeam assembly 200 is connected to the side of the front bulkhead 100 facing away from the passenger compartment. Specifically, the windshield crossbeam assembly 200 includes an upper windshield crossbeam 210 and a lower windshield crossbeam 220. The lower windshield crossbeam 220 is connected to one side of the front bulkhead 100 and extends in a direction facing away from the front bulkhead 100, which can be understood as the vehicle's longitudinal direction. The upper windshield crossbeam 210 is connected to the side of the lower windshield crossbeam 220 facing away from the front bulkhead 100 and extends in a direction facing away from the front bulkhead 100. This forms a protective area 300 between the upper windshield crossbeam 210 and the lower windshield crossbeam 220. The protective area 300 is as follows: Figure 1 As shown by the dotted line, when the protected area 300 of the windshield beam assembly 200 collides, the lower windshield plate 220, facing away from the upper windshield plate 210, has no hard points or supports, or in other words, the portion of the lower windshield plate 220 facing away from the upper windshield plate 210, except for the edge, has no hard points or supports. This results in the windshield beam assembly 200 being in a suspended state, and the lower windshield plate 220 having a large buffer energy range. Furthermore, one end of the lower windshield plate 220 is connected to the front bulkhead 100 and extends in a direction away from the front bulkhead 100, so that in the event of a frontal collision, the upper windshield plate 210 and the lower windshield plate 220 act as the first-time force-bearing components, while the front bulkhead 100 acts as the second-time force-bearing component, reducing the risk of collision force intrusion into the cabin. The windshield beam assembly 200 has an arc at the end away from the front bulkhead 100 in the extension direction X. Specifically, the upper windshield beam 210 has a first arc surface at the end away from the front bulkhead 100, and the center of the first arc surface is located on the side close to the lower windshield beam 220. This allows the windshield beam assembly 200 to transmit the impact force to both ends of the windshield beam assembly 200 when it is hit, thereby further improving the ability to protect the occupants of the vehicle.

[0034] In some embodiments, the vehicle front-end assembly 10 may further include a lower crossbeam and two shock absorber towers. The two shock absorber towers are spaced apart in the longitudinal direction Y of the windshield crossbeam assembly 200. The lower crossbeam is connected to the end of the front bulkhead 100 away from the lower windshield crossbeam 220. The two shock absorber towers are connected to the lower crossbeam and are located on the side of the front bulkhead 100 near the lower windshield crossbeam 220. The dimension of the lower windshield crossbeam 220 in the extension direction X is equal to or greater than the dimension from the end of the shock absorber tower away from the front bulkhead 100 to the front bulkhead 100, thereby forming a larger protection area 300.

[0035] In the above-described embodiment, the lower windshield beam 220 extends away from the front bulkhead 100. The front bulkhead 100 and the upper windshield beam 210 are respectively connected to both sides of the lower windshield beam 220 and extend away from the lower windshield beam 220. The front bulkhead 100 and the upper windshield beam 210 are also spaced apart in the extension direction X, so that the lower windshield beam 220 is suspended and a protective area 300 is formed between the lower windshield beam 220 and the upper windshield beam 210, which can effectively protect both vehicle occupants and pedestrians.

[0036] In some embodiments, the windshield crossbeam assembly 200 includes an upper crossbeam 211, which extends along the length direction Y of the upper windshield crossbeam 210. The upper crossbeam 211 is connected to one side of the upper windshield crossbeam 210, and a first energy-absorbing cavity is formed between the upper crossbeam 211 and the upper windshield crossbeam 210.

[0037] The upper crossbeam 211 is connected to one side of the upper windshield crossbeam 210. It can be located on the side of the upper windshield crossbeam 210 near the lower windshield crossbeam 220, or on the side of the upper windshield crossbeam 210 away from the lower windshield crossbeam 220. This improves the structural strength of the upper windshield crossbeam 210, enhances the collision performance of the vehicle's front-end assembly 10, and improves the ability to protect the vehicle occupants. Furthermore, the upper crossbeam 211 and the upper windshield crossbeam 210 form a first energy-absorbing cavity, which is located along the side of the upper windshield crossbeam 210, further improving the collision performance of the vehicle's front-end assembly 10.

[0038] In some embodiments, the windshield beam assembly 200 includes two windshield beam side plates 240. One windshield beam side plate 240 connects the windshield beam upper plate 210 and one end of the windshield beam upper plate 210 in the length direction Y. The other windshield beam side plate 240 connects the windshield beam upper plate 210 and the other end of the windshield beam lower plate 220. The two ends of the upper plate beam 211 in the length direction Y are respectively connected to one windshield beam side plate 240.

[0039] The windshield beam assembly 200 also includes two windshield beam side plates 240, located at both ends of the windshield beam assembly 200 in the length direction Y. One windshield beam side plate 240 is connected to the same end of the upper windshield plate 210 and the lower windshield beam 220, while the other windshield beam side plate 240 is connected to the other end of the upper windshield plate 210 and the lower windshield beam 220. That is, one end of the upper windshield plate 210 and the lower windshield beam 220 in the length direction Y is connected by one windshield beam side plate 240, and the other end of the upper windshield plate 210 and the lower windshield beam 220 in the length direction Y is connected by the other windshield beam side plate 240. This allows the impact force on the upper windshield plate 210 to be transmitted to the windshield beam side plates 240 at both ends. Each windshield crossbeam side panel 240 can be connected to an A-pillar at the end furthest from the windshield crossbeam upper panel 210 in the length direction Y. This allows the frontal collision force to be transferred to the vehicle body via the A-pillar. The frontal collision force can be understood as the windshield crossbeam assembly 200 experiencing a collision force in the extension direction X. This reduces the collision force on the front bulkhead 100 and improves the ability to protect the occupants. In addition, each end of the upper panel crossbeam 211 is also connected to a corresponding windshield crossbeam side panel 240. When subjected to a side collision, the windshield crossbeam side panel 240 can act as the first force-bearing component and transfer the collision force to the other windshield crossbeam side panel 240 through the windshield crossbeam upper panel 210, windshield crossbeam lower panel 220, and upper panel crossbeam 211. Therefore, the lower plate crossbeam is connected to one side of the upper plate 210 of the windshield crossbeam, and both ends of the lower plate crossbeam are also connected to the two windshield crossbeam side plates 240, which can improve the frontal collision performance of the vehicle front assembly 10 and the side collision performance of the vehicle front assembly 10.

[0040] In some embodiments, the vehicle front-end assembly 10 may further include a windshield glass that covers the upper windshield beam 210 and the ends of the two windshield beam side panels 240 away from the lower windshield beam 220, so that the windshield glass corresponds to the protection area 300 and forms a large buffer area between the two windshield beam side panels 240 and the upper windshield beam 210, reducing the risk of direct impact with the lower windshield beam 220. When a collision occurs, the buffer area can first cushion the impacting object and then transmit the impact force to the lower windshield beam 220. This further improves the protection of pedestrians on the road.

[0041] See Figure 2 , Figure 2 yes Figure 1 The diagram shown is a second-view structural schematic of the vehicle's front-end assembly.

[0042] In some embodiments, the windshield beam assembly 200 includes a lower longitudinal beam 221, which extends in the extension direction X. The lower longitudinal beam 221 connects to one side of the lower windshield beam 220 and the upper windshield beam 210. The orthographic projections of the lower longitudinal beam 221 and the upper transverse beam 211 on the upper windshield beam 210 overlap.

[0043] The lower longitudinal beam 221 extends in the X-direction and connects to one side of the lower plate 220 and the upper plate 210 of the windshield crossbeam. The orthographic projections of the lower longitudinal beam 221 and the upper plate crossbeam 211 onto the upper plate 210 of the windshield crossbeam overlap. The lower plate 220 can be located on the side away from the front bulkhead 100, and the upper plate 210 can be located on the side close to the front bulkhead 100; alternatively, the lower plate 220 can be located on the side close to the front bulkhead 100, and the upper plate 210 can be located on the side away from the front bulkhead 100. As an example, the lower longitudinal beam 221 is connected to the side of the lower windshield beam 220 away from the front bulkhead 100 and the side of the upper windshield beam 210 close to the front bulkhead 100. The connection between the lower longitudinal beam 221 and the upper windshield beam 210 can be located between the upper windshield beam 211 and the lower windshield beam 220. In addition to being connected to the upper windshield beam 210, the lower longitudinal beam 221 can also be connected to the upper windshield beam 211, so that the projections of the lower longitudinal beam 221 and the upper windshield beam 211 on the upper windshield beam 210 can partially overlap. As a result, the collision force on the upper windshield beam 211 and the upper windshield beam 210 can be transmitted to the lower longitudinal beam 221, thereby improving the frontal collision performance of the vehicle front end assembly 10. The end of the lower longitudinal beam 221 away from the upper plate 210 of the windshield crossbeam can also be connected to the front bulkhead 100. This allows the impact force to be transmitted to the front bulkhead 100 via the lower longitudinal beam 221, reducing the pressure at the connection points between the front bulkhead 100 and other components, and lowering the risk of localized damage to the front bulkhead 100. As another example, the lower longitudinal beam 221 is connected to the side of the lower plate 220 of the windshield crossbeam near the front bulkhead 100 and the side of the upper plate 210 of the windshield crossbeam away from the front bulkhead 100. Specifically, the lower longitudinal beam 221 may include a bent upper plate connecting portion and a lower plate connecting portion. The lower plate connecting portion is connected to the side of the lower plate 220 of the windshield crossbeam near the front bulkhead 100, and the upper plate connecting portion is connected to the side of the upper plate 210 of the windshield crossbeam away from the lower plate 220. This allows the lower longitudinal beam 221 and the upper plate 210 of the windshield crossbeam to share the impact force, improving collision performance. The end of the lower panel connecting part away from the upper panel connecting part can also be connected to the front bulkhead 100, so that the collision force can be transmitted to the front bulkhead 100 through the lower panel longitudinal beam 221, which can not only improve the structural strength of the front end assembly 10 of the vehicle, but also reduce the risk of local damage to the front bulkhead 100.

[0044] In this embodiment, the lower longitudinal beam 221 can also form a second energy-absorbing cavity between the upper plate 210 and the lower plate 220 of the windshield crossbeam to further improve the impact performance of the vehicle front end assembly 10 and protect the occupants.

[0045] In some embodiments, there are multiple lower plate longitudinal beams 221, which are spaced apart in the length direction Y, and the orthogonal projections of each lower plate longitudinal beam 221 and the upper plate crossbeam 211 on the upper plate 210 of the windshield crossbeam overlap.

[0046] There are multiple lower plate longitudinal beams 221, which are spaced apart in the length direction Y. The orthogonal projections of each lower plate longitudinal beam 221 and the upper plate crossbeam 211 on the upper plate 210 of the windshield crossbeam overlap, so that each lower plate longitudinal beam 221 can transmit the collision force, and can also cooperate with the upper plate 210 of the windshield crossbeam and / or the upper plate crossbeam 211 to transmit the collision force, thereby improving the collision performance of the front end assembly 10 of the vehicle and protecting the occupants.

[0047] In some embodiments, the vehicle front end assembly 10 further includes a force transmission vertical beam 110, which extends along the height direction Z of the front bulkhead 100 and is disposed on the side of the front bulkhead 100 near the lower plate 220 of the windshield crossbeam. The lower plate longitudinal beam 221 is connected to the side of the lower plate 220 of the windshield crossbeam near the front bulkhead 100, and one end of the force transmission vertical beam 110 is supported on the lower plate longitudinal beam 221.

[0048] The lower longitudinal beam 221 can be connected to the side of the lower plate 220 of the windshield crossbeam near the front bulkhead 100 and extends in the extension direction X. Furthermore, the vehicle front-end assembly 10 also includes a force-transmitting vertical beam 110, which is connected to the side of the front bulkhead 100 near the lower plate 220 of the windshield crossbeam. The force-transmitting vertical beam 110 extends in the height direction Z of the front bulkhead 100 and connects to the lower longitudinal beam 221, allowing the lower longitudinal beam 221 to transmit collision force to the force-transmitting vertical beam 110. When subjected to a frontal collision (i.e., a collision in the extension direction X) or a collision from the height direction Z, the force-transmitting vertical beam 110 can withstand the frontal collision force and transmit the collision force from one end of the force-transmitting vertical beam 110 near the lower longitudinal beam 221 to the end away from the lower longitudinal beam 221. Therefore, the force-transmitting vertical beam 110 improves the collision performance of the vehicle front-end assembly 10.

[0049] Furthermore, the end of the force-transmitting vertical beam 110 near the lower plate 220 of the windshield crossbeam can be connected to the side of the lower plate longitudinal beam 221 opposite to the lower plate 220 of the windshield crossbeam, so that the force-transmitting vertical beam 110 can provide support force to the lower plate longitudinal beam 221 in the height direction Z. This reduces the risk of secondary injuries caused by a large impact force from the height direction Z on the lower plate 220 of the windshield crossbeam, which could lead to severe deformation of the lower plate 220 and impact with various components inside the engine compartment. This further improves the protection of pedestrians on the road.

[0050] See Figure 3 , Figure 3 yes Figure 2 The diagram shows an enlarged structural schematic of the vehicle's front-end assembly at the dashed box O.

[0051] In some embodiments, the force-transmitting vertical beam 110 includes a vertical beam body 111 and a vertical beam support portion 112. The vertical beam body 111 is spaced apart from the lower plate longitudinal beam 221 in the height direction Z. The two ends of the vertical beam support portion 112 are respectively connected to the vertical beam body 111 and the lower plate longitudinal beam 221. The vertical beam support portion 112 and the vertical beam body 111 are arranged at an obtuse angle.

[0052] The connection between the force-transmitting vertical beam 110 and the lower plate longitudinal beam 221 can be arranged in a triangular structure, thereby improving the structural stability of the connection between the force-transmitting vertical beam 110 and the lower plate longitudinal beam 221. For example, the force-transmitting vertical beam 110 may include a vertical beam body 111 and a vertical beam support portion 112. The vertical beam body 111 extends in the height direction Z and is connected to the side of the front bulkhead 100 near the lower plate 220 of the windshield crossbeam. The vertical beam body 111 may be spaced apart from the lower plate longitudinal beam 221 in the height direction Z. One end of the vertical beam support portion 112 is connected to the end of the vertical beam body 111 near the lower plate longitudinal beam 221, and the other end of the vertical beam support portion 112 is connected to the side of the lower plate longitudinal beam 221 near the vertical beam body 111. The vertical beam support portion 112 and the vertical beam body 111 are arranged at an obtuse angle. The vertical beam support 112 is supported between the vertical beam body 111 and the lower plate longitudinal beam 221, and the corresponding parts of the vertical beam support 112, the lower plate longitudinal beam 221 and the front bulkhead 100 form a stable triangular structure, thereby further improving the collision performance of the vehicle front assembly 10, improving the load-bearing capacity of the windshield crossbeam lower plate 220, and improving the protection of pedestrians on the road.

[0053] Of course, in some other embodiments, one end of the vertical beam body 111 may also be connected to the lower plate 220 of the windshield crossbeam. For example, one end of the vertical beam body 111 and one end of the lower plate longitudinal beam 221 are both located at the connection between the lower plate 220 of the windshield crossbeam and the front bulkhead 100, so that one end of the vertical beam body 111 is connected to the lower plate 220 of the windshield crossbeam, and one end of the lower plate longitudinal beam 221 is also connected to the front bulkhead 100. The vertical beam support 112 is supported between the lower plate longitudinal beam 221 and the vertical beam body 111. Specifically, the vertical beam support 112 may include a middle support and end connecting parts connected to both ends of the middle support. The two end connecting parts are respectively disposed opposite to and connected to the side of the lower plate longitudinal beam 221 near the vertical beam body 111 and the side of the vertical beam body 111 near the lower plate longitudinal beam 221. The middle support is triangularly arranged with the vertical beam body 111 and the lower plate longitudinal beam 221. This improves the collision performance of the vehicle's front-end assembly 10 and its ability to protect pedestrians on the road.

[0054] In some embodiments, the lower plate 220 of the windshield beam is provided with a wire harness mounting hole 222, which penetrates the two opposite surfaces of the lower plate 220 of the windshield beam.

[0055] Understandably, the wiring harness mounting hole 222 allows the wiring harness to pass through, enabling it to electrically connect various electrical components on opposite sides of the lower plate 220 of the windshield beam. Consequently, the wiring harness can hang naturally under gravity, and its downward path avoids the damping tower on one side of the lower plate 220 of the windshield beam, eliminating the need for manual adjustment of the wiring harness position and significantly reducing assembly time.

[0056] In some embodiments, the connection between the upper plate 210 and the lower plate 220 of the windshield beam is set at an obtuse angle.

[0057] Therefore, the connection between the upper plate 210 and the lower plate 220 of the windshield beam is set at an obtuse angle. Without increasing the size of the lower plate 220 of the windshield beam, the area of ​​the protected area 300 can be increased. This not only maintains the structural strength of the front end assembly 10 of the vehicle, but also further improves the protection of pedestrians on the road.

[0058] In summary, the lower windshield beam 220 extends away from the front bulkhead 100. The front bulkhead 100 and the upper windshield beam 210 are respectively connected to both sides of the lower windshield beam 220 and extend away from the lower windshield beam 220.
