Furthermore, safety regulations are imposing increasingly stringent requirements on the pedestrian head impact safety performance of vehicles, making pedestrian safety a key consideration in vehicle manufacturing. Existing vehicle front assemblies have high structural strength at the pedestrian head impact point, resulting in less deformation at the impact site after a collision. This leads to a higher risk of head injury to pedestrians during a collision, indicating room for improvement. Utility Model Content

[0035] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0036] The following is for reference. Figures 1-2 The front fascia component 100 according to the present invention has a simple structure, is easy to install, can reduce production costs, can weaken the structural strength at the point of impact with a pedestrian's head, improve pedestrian safety, and can improve weight reduction to enhance vehicle range performance.

[0037] like Figures 1-2 As shown, a front enclosure assembly 100 according to an embodiment of the present invention includes: an upper front enclosure plate 1 and a lower front enclosure plate 2.

[0038] The upper front panel 1 is connected to the upper side of the lower front panel 2 and together with the lower front panel 2 defines the buffer cavity 3; wherein, the upper front panel 1 includes a first upper panel portion 11 and a second upper panel portion 12 for defining the buffer cavity 3, and the lower front panel 2 includes a first lower panel portion 21 and a second lower panel portion 22 for defining the buffer cavity 3, the first upper panel portion 11 and the second lower panel portion 22 are distributed in a first direction, and the second upper panel portion 12 and the first lower panel portion 21 are distributed in a second direction, and the first direction intersects the second direction.

[0039] Specifically, the front bulkhead assembly 100 is located in the front engine compartment of the vehicle. The upper part of the front bulkhead assembly 100 can be connected to the windshield by means of bonding or other methods, and the lower part of the front bulkhead assembly 100 can be welded to the front bulkhead panel 101. The front bulkhead panel 101 is located between the engine compartment and the passenger compartment. The lower end of the front bulkhead panel 101 is connected to the floor, and the left and right sides of the front bulkhead panel 101 are connected to the left and right A-pillars of the vehicle, respectively. The front bulkhead panel 101 is provided with openings for passing through control cables, levers, pipes, and wiring harnesses to ensure the reliability of vehicle operation. The front part of the front bulkhead assembly 100 can be connected to a connecting bracket, which is connected to shock absorbers, etc., so that when the vehicle is involved in a collision, the collision force can be transmitted to the front bulkhead assembly 100 through the connecting bracket, and then transmitted to the front bulkhead panel 101 and other structures through the front bulkhead assembly 100, thereby dispersing the effect of the collision force and ensuring the safety of vehicle use.

[0040] Furthermore, the front enclosure assembly 100 is provided with an upper front enclosure plate 1 and an upper front enclosure plate 2. The upper front enclosure plate 1 is located above the lower front enclosure plate 2. Both the upper front enclosure plate 1 and the lower front enclosure plate 2 can be made of a single piece of sheet metal and can be manufactured by processes such as stamping. In this embodiment, the thickness of both the upper front enclosure plate 1 and the lower front enclosure plate 2 can be set to 0.6mm. The structure is simple and can ensure the structural strength of the upper front enclosure plate 1 and the lower front enclosure plate 2. The upper front enclosure plate 1 and the lower front enclosure plate 2 can be connected by welding or other methods, which is convenient for installation and can reduce production costs.

[0041] Furthermore, the upper front panel 1 and the lower front panel 2 together define the buffer cavity 3. The buffer cavity 3 can improve the lightweight of the front assembly 100, thereby improving the overall vehicle lightweight, which in turn can improve the vehicle's range performance and user experience. When the vehicle is involved in a collision, the collision force can be transmitted to the front assembly 100, and the buffer cavity 3 can buffer the collision force to weaken the collision effect, thereby improving the vehicle's safety.

[0042] In addition, the upper front panel 1 is provided with a first upper panel 11 and a second upper panel 12. The first upper panel 11 and the second upper panel 12 are configured to be bent and connected in sequence along the front-rear direction of the vehicle. The lower front panel 2 is provided with a first lower panel 21 and a second lower panel 22. The first lower panel 21 and the second lower panel 22 are configured to be bent and connected in sequence along the front-rear direction of the vehicle. The first upper panel 11 and the second lower panel 22 are distributed in a first direction, and the second upper panel 12 and the first lower panel 21 are distributed in a second direction. The first direction and the second direction intersect. The first upper panel 11, the second upper panel 12, the first lower panel 21 and the second lower panel 22 are all used to define the buffer cavity 3, so that the buffer cavity 3 can be constructed as a quadrilateral cavity.

[0043] In this way, by constructing the buffer cavity 3 as a quadrilateral cavity, the structural strength of the first upper plate 11, the second upper plate 12, the first lower plate 21 and the second lower plate 22 can be weakened. When the front enclosure assembly 100 is subjected to a collision force, the front enclosure assembly 100 will collapse and cave in, thereby reducing the reaction force on the pedestrian's head and improving pedestrian safety.

[0044] According to the front enclosure assembly 100 of this utility model embodiment, the upper front panel 1 and the lower front panel 2 together define a buffer cavity 3, which can buffer the impact force to reduce the effect of the impact and improve the vehicle's range performance. The first upper panel 11 and the second lower panel 22 are distributed in the first direction, and the second upper panel 12 and the first lower panel 21 are distributed in the second direction, so that the buffer cavity 3 defined by the first upper panel 11, the second upper panel 12, the first lower panel 21 and the second lower panel 22 is a quadrilateral cavity. This weakens the structural strength of the front enclosure assembly 100, making it easier for the front enclosure assembly 100 to collapse when subjected to impact force, thereby reducing the reaction force on the pedestrian's head, improving pedestrian protection safety, and having a better effect and wider application range.

[0045] In some embodiments, the included angle between the first upper plate portion 11 and the second upper plate portion 12 is set as α, and satisfies: 90°≤α≤110°.

[0046] Specifically, such as Figures 1-2As shown, the upper front panel 1 is provided with a first upper panel 11 and a second upper panel 12 that are bent and connected sequentially along the front-rear direction of the vehicle, so that there is an included angle between the first upper panel 11 and the second upper panel 12. The included angle between the first upper panel 11 and the second upper panel 12 can be set as α, and satisfy: 90°≤α≤110°. That is, the included angle α between the first upper panel 11 and the second upper panel 12 can be set to 90°, 92°, 94°, 96°, 98°, 100°, 102°, 104°, 106°, 108° or 110°, etc. In this embodiment, the included angle α between the first upper panel 11 and the second upper panel 12 is set to 98°.

[0047] Therefore, setting the included angle between the first upper plate 11 and the second upper plate 12 too small or too large can easily lead to low structural strength of the upper plate 1 of the front enclosure, which in turn can easily lead to damage to the front enclosure assembly 100. Therefore, setting the included angle α between the first upper plate 11 and the second upper plate 12 to satisfy: 90°≤a≤110°, that is, setting the included angle α between the first upper plate 11 and the second upper plate 12 to an obtuse angle can ensure the reliability of the front enclosure assembly 100. Furthermore, when the front enclosure assembly 100 is subjected to a collision force, the first upper plate 11 can be deformed towards the second upper plate 12, thereby reducing the reaction force on the pedestrian's head and improving pedestrian safety.

[0048] In other embodiments, the angle between the first upper plate portion 11 and the horizontal plane is set to b, and satisfies: 35°≤b≤45°.

[0049] Specifically, the front part of the upper plate 1 of the front enclosure is provided with a first upper plate portion 11. The first upper plate portion 11 is inclined so that there is an angle between the first upper plate portion 11 and the horizontal plane. The angle between the first upper plate portion 11 and the horizontal plane is set as b, and satisfies: 35°≤b≤45°. That is, the angle b between the first upper plate portion 11 and the horizontal plane can be set to 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44° or 45°, etc. In this embodiment, the angle b between the first upper plate portion 11 and the horizontal plane is set to 37.4°.

[0050] In addition, the first upper plate 11 is disposed at the front of the upper plate 1 of the front bulkhead, and the upper part of the front bulkhead assembly 100 can be connected to the windshield by means of bonding or the like. That is, the lower end of the windshield is connected to the first upper plate 11 by means of bonding or the like, so that the windshield and the first upper plate 11 are arranged parallel to each other, and the included angle between the windshield and the horizontal plane is also set to be greater than or equal to 35° and less than or equal to 45°.

[0051] Furthermore, during the simulated collision, the angle between the impact angle of the head-shaped impactor and the horizontal line is 65°, and the angle between the impact direction and the windshield is set to 77.6°. Setting the angle between the first upper plate 11 and the horizontal plane to be too large or too small can easily cause the impact force to deviate from the front assembly 100. That is, setting the angle b between the first upper plate 11 and the horizontal plane to satisfy: 35°≤b≤45° can ensure that when a collision occurs, the impact force acts on the front assembly 100 as much as possible, so that when the front assembly 100 deforms, the impact force can be buffered, thereby improving pedestrian safety.

[0052] In some embodiments, the length of the second upper plate portion 12 is set to L1, and satisfies: L1≥104.3mm.

[0053] Specifically, such as Figures 1-2 As shown, the upper front panel 1 is provided with a first upper panel portion 11 and a second upper panel portion 12 connected together. The second upper panel portion 12 is connected to the rear end of the first upper panel portion 11, and the end of the second upper panel portion 12 away from the first upper panel portion 11 is inclined downward. The length of the second upper panel portion 12 is set to L1, and satisfies: L1≥104.3mm, that is, the length L1 of the second upper panel portion 12 can be set to 104.3mm, 105mm, 105.5mm, 106mm, 106.5mm, 107mm, 107.5mm, 108mm, 108.5mm, 109mm or 109.5mm. In this embodiment, the length L1 of the second upper panel portion 12 is set to 104.3mm.

[0054] In other embodiments, the distance from the connection position of the first lower plate portion 21 and the second lower plate portion 22 to the first upper plate portion 11 is set to L2, and satisfies: L2≥71.5mm.

[0055] Specifically, such as Figures 1-2 As shown, the first lower plate portion 21 and the second upper plate portion 12 are distributed in the second direction, and the first upper plate portion 11 and the second lower plate portion 22 are distributed in the first direction, such that the extending direction of the first lower plate portion 21 intersects with the first upper plate portion 11, and the distance from the connection position of the first lower plate portion 21 and the second lower plate portion 22 to the first upper plate portion 11 is set to L2, and satisfies: L2≥71.5mm, that is, the distance L2 from the connection position of the first lower plate portion 21 and the second lower plate portion 22 to the first upper plate portion 11 can be set to 71.5mm, 72mm, 72.5mm, 73mm, 73.5mm, 74mm, 74.5mm, 75mm, 75.5mm, 76mm or 76.5mm. In this embodiment, the distance L2 from the connection position of the first lower plate portion 21 and the second lower plate portion 22 to the first upper plate portion 11 is set to 71.5mm.

[0056] Thus, by setting the length L1 of the second upper plate portion 12 to satisfy: L1≥104.3mm, and setting the distance L2 from the connection position of the first lower plate portion 21 and the second lower plate portion 22 to the first upper plate portion 11 to satisfy: L2≥71.5mm, the front bulkhead assembly 100 can be minimized in the front-rear direction while satisfying the impact angle. This can improve the lightweight of the front bulkhead assembly 100, reduce the space occupied by the front bulkhead assembly 100, reduce the installation cost, and improve the overall vehicle lightweighting, thereby improving the vehicle's range performance.

[0057] In other embodiments, the second upper plate portion 12 and the first lower plate portion 21 are arranged in parallel.

[0058] Specifically, a second upper plate 12 is provided at the rear of the upper front panel 1, and a first lower plate 21 is provided at the front of the lower front panel 2. The second upper plate 12 and the first lower plate 21 are distributed in the second direction, and the second upper plate 12 and the first lower plate 21 can be arranged in parallel, so that the distance between the second upper plate 12 and the first lower plate 21 is equal. When the collision force acts on the front panel assembly 100, that is, when the collision force acts on the first upper plate 11, it can be transmitted rearward along the second upper plate 12 and the first lower plate 21 respectively, thereby dispersing the effect of the collision force and ensuring the reliability of the front panel assembly 100.

[0059] In some other embodiments, the distance between the second upper plate portion 12 and the first lower plate portion 21 is set to L3, and satisfies: L3≥38.6mm.

[0060] Specifically, the second upper plate portion 12 and the first lower plate portion 21 are spaced apart in the second direction and are arranged in parallel. The distance between the second upper plate portion 12 and the first lower plate portion 21 is set to L3, and satisfies: L3≥38.6mm, that is, the distance L3 between the second upper plate portion 12 and the first lower plate portion 21 can be set to 38.6mm, 39mm, 39.5mm, 40mm, 40.5mm, 41mm, 41.5mm, 42mm, 42.5mm, 43mm or 43.5mm, etc. In this embodiment, the distance L3 between the second upper plate portion 12 and the first lower plate portion 21 is set to 38.6mm.

[0061] Thus, the first upper plate 11 is connected between the second upper plate 12 and the lower upper plate 2 of the front bulkhead, so that the minimum set length of the first upper plate 11 is the distance between the second upper plate 12 and the first lower plate 21. Setting the distance L3 between the second upper plate 12 and the first lower plate 21 to satisfy: L3≥38.6mm can avoid the first upper plate 11 being too short, thereby ensuring the reliability of the connection between the first upper plate 11 and the windshield, and reducing the space occupied by the front bulkhead assembly 100, thus improving the vehicle's lightweight design.

[0062] In some embodiments, the upper front panel 1 further includes a front connecting plate 13 and a rear connecting plate 14. The first upper panel portion 11 and the second upper panel portion 12 are bent and connected between the front connecting plate 13 and the rear connecting plate 14, and the front connecting plate 13 and the rear connecting plate 14 are respectively connected to the lower front panel 2.

[0063] Specifically, the upper front panel 1 is connected above the lower front panel 2, and the upper front panel 1 is also provided with a front connecting plate 13 and a rear connecting plate 14. The first upper panel 11 and the second upper panel 12 are bent and connected between the front connecting plate 13 and the rear connecting plate 14. That is, the front connecting plate 13 is connected to the front end of the first upper panel 11, and the rear connecting plate 14 is connected to the rear end of the second upper panel 12. The front connecting plate 13 can be connected to the lower front panel 2 by welding or other means, and the rear connecting plate 14 can also be connected to the lower front panel 2 by welding or other means, so that the upper front panel 1 can be connected above the lower front panel 2.

[0064] Furthermore, the front connecting plate 13 of the upper plate can be configured as a straight plate structure, which can increase the contact area between the front connecting plate 13 of the upper plate and the lower plate 2 of the front bulkhead, thereby improving the reliability of the connection between the front connecting plate 13 of the upper plate and the lower plate 2 of the front bulkhead. The rear connecting plate 14 of the upper plate can also be configured as a straight plate structure, which can increase the contact area between the rear connecting plate 14 of the upper plate and the lower plate 2 of the front bulkhead, thereby improving the reliability of the connection between the rear connecting plate 14 of the upper plate and the lower plate 2 of the front bulkhead, and thus improving the reliability of the connection between the upper plate 1 of the front bulkhead and the lower plate 2 of the front bulkhead.

[0065] In some embodiments, the length of the upper front connecting plate 13 is set to L4, and satisfies: L4≥24mm.

[0066] Specifically, the upper plate front connecting plate 13 is connected to the front end of the first upper plate part 11 and is connected to the lower plate of the front enclosure 2 by welding or other means. The length of the upper plate front connecting plate 13 is set to L4, and satisfies: L4≥24mm, that is, the length L4 of the upper plate front connecting plate 13 can be set to 24mm, 24.5mm, 25mm, 25.5mm, 26mm, 26.5mm, 27mm, 27.5mm, 28mm, 28.5mm or 29mm, etc. In this embodiment, the length L4 of the upper plate front connecting plate 13 is set to 24mm.

[0067] Furthermore, the front end length of the front panel assembly 100 is determined by the length of the upper front connecting plate 13. Setting the length of the upper front connecting plate 13 too small will affect the reliability of the connection between the upper front connecting plate 13 and the upper lower front panel 2. Therefore, setting the length L4 of the upper front connecting plate 13 to satisfy: L4≥24mm, can reduce the overall space occupied by the front panel assembly 100 while ensuring the reliability of the connection between the upper front connecting plate 13 and the upper lower front panel 2.

[0068] In other embodiments, the length of the connecting plate 14 after the upper plate is set to L5, and satisfies: L5≥56.7mm.

[0069] Specifically, the upper plate rear connecting plate 14 is connected to the rear end of the second upper plate part 12 and is connected to the front upper lower plate 2 by welding or other means. The length of the upper plate rear connecting plate 14 is set to L5, and satisfies: L5≥56.7mm, that is, the length L5 of the upper plate rear connecting plate 14 can be set to 56.7mm, 57mm, 57.5mm, 58mm, 58.5mm, 59mm, 59.5mm or 60mm, etc. In this embodiment, the length L5 of the upper plate rear connecting plate 14 is set to 56.7mm.

[0070] Furthermore, the rear end length of the front bulkhead assembly 100 is determined by the length of the upper rear connecting plate 14. Setting the length of the upper rear connecting plate 14 too small will affect the reliability of the connection between the upper rear connecting plate 14 and the upper lower front bulkhead 2. Therefore, setting the length L5 of the upper rear connecting plate 14 to satisfy: L5≥56.7mm, can reduce the overall space occupied by the front bulkhead assembly 100 while ensuring the reliability of the connection between the upper rear connecting plate 14 and the upper lower front bulkhead 2.

[0071] In actual installation, the length L4 of the front connecting plate 13 of the upper plate is set to meet the requirement of L4≥24mm, and the length L5 of the rear connecting plate 14 of the upper plate is set to meet the requirement of L5≥56.7mm, which can meet the welding process requirements and ensure the reliability of the connection.

[0072] In some embodiments, the upper lower panel 2 of the front enclosure further includes a lower panel front connecting plate 23, the first lower panel portion 21 and the second lower panel portion 22 are bent and connected to the rear side of the lower panel front connecting plate 23 in sequence, and the lower panel front connecting plate 23 and the second lower panel portion 22 are respectively connected to the upper upper panel 1 of the front enclosure.

[0073] Specifically, the lower front panel 2 is connected to the lower side of the upper front panel 1, and as follows: Figure 1As shown, the upper lower plate 2 of the front enclosure is also provided with a lower plate front connecting plate 23. The lower plate front connecting plate 23 is located at the front of the upper lower plate 2 of the front enclosure, and the rear end of the lower plate front connecting plate 23 is bent and connected to the front end of the first lower plate part 21. The rear end of the first lower plate part 21 is bent and connected to the front end of the second lower plate part 22, so that the first lower plate part 21 and the second lower plate part 22 can be bent and connected to the rear side of the lower plate front connecting plate 23 in sequence.

[0074] Furthermore, the lower front connecting plate 23 can be connected to the upper front panel 1 by welding or other means, and the lower front connecting plate 23 is set as a straight plate structure, which can increase the contact area between the lower front connecting plate 23 and the upper front panel 1, thereby improving the connection reliability between the lower front connecting plate 23 and the upper front panel 1. The second lower plate part 22 can be connected to the upper front panel 1 by welding or other means, and the second lower plate part 22 is also set as a straight plate structure, thereby increasing the contact area between the second lower plate part 22 and the upper front panel 1, thereby improving the connection reliability between the second lower plate part 22 and the upper front panel 1.

[0075] In some embodiments, the included angle between the lower plate front connecting plate 23 and the first lower plate portion 21 is set to c, and satisfies: 110°≤c≤130°.

[0076] Specifically, the rear end of the lower plate front connecting plate 23 is bent and connected to the first lower plate portion 21, so that there is an included angle between the lower plate front connecting plate 23 and the first lower plate portion 21, and the included angle between the lower plate front connecting plate 23 and the first lower plate portion 21 is set as c, and satisfies: 110°≤c≤130°, that is, the included angle c between the lower plate front connecting plate 23 and the first lower plate portion 21 can be set to 110°, 112°, 114°, 116°, 118°, 120°, 122°, 124°, 126°, 128° or 130°, etc. In this embodiment, the included angle c between the lower plate front connecting plate 23 and the first lower plate portion 21 is set to 123°.

[0077] Therefore, setting the included angle between the lower plate front connecting plate 23 and the first lower plate part 21 too small or too large can easily lead to low structural strength of the upper lower plate 2 of the front enclosure, which in turn can easily lead to damage to the front enclosure assembly 100. Therefore, setting the included angle c between the lower plate front connecting plate 23 and the first lower plate part 21 to satisfy: 110°≤c≤130°, that is, setting the included angle c between the lower plate front connecting plate 23 and the first lower plate part 21 to an obtuse angle can ensure the reliability of the front enclosure assembly 100. Moreover, when the front enclosure assembly 100 is subjected to a collision force, the lower plate front connecting plate 23 can be deformed towards the first lower plate part 21, thereby reducing the reaction force on the pedestrian's head and improving pedestrian protection safety.

[0078] In some embodiments, the front bulkhead assembly 100 further includes a front bulkhead panel 101, which is connected below the upper lower front bulkhead panel 2.

[0079] Specifically, the front bulkhead assembly 100 is also provided with a front bulkhead panel 101. The front bulkhead panel 101 is connected to the lower part of the upper front bulkhead lower plate 2. That is, the upper end of the front bulkhead panel 101 can be connected to the lower side of the second lower plate 22 by welding or other means. The front bulkhead panel 101 is located between the engine compartment and the passenger compartment. The lower end of the front bulkhead panel 101 is connected to the floor. The left and right sides of the front bulkhead panel 101 are connected to the left and right A-pillars of the vehicle, respectively. The front bulkhead panel 101 is provided with openings for passing through control cables, levers, pipes and wiring harnesses, etc., to ensure the reliability of vehicle operation.

[0080] In other embodiments, the front enclosure assembly 100 further includes a reinforcing plate 4 disposed within the buffer cavity 3 and connected to the inner wall of the buffer cavity 3.

[0081] Specifically, such as Figures 1-2 As shown, the front bulkhead assembly 100 is also provided with a reinforcing plate 4, which can be disposed in the buffer cavity 3. The reinforcing plate 4 can be connected to the inner wall of the buffer cavity 3 by welding or other means, thereby improving the structural strength of part of the buffer cavity 3. This allows the front bulkhead assembly 100 to still transmit the collision force to the front bulkhead panel 101 and other structures after deformation, so as to ensure the safety of vehicle use.

[0082] In some embodiments, the reinforcing plate 4 includes a first sub-segment 41, a second sub-segment 42 and a third sub-segment 43, the second sub-segment 42 being bent and connected between the first sub-segment 41 and the third sub-segment 43, the first sub-segment 41 being connected to the first lower plate portion 21, and the third sub-segment 43 being connected to the second lower plate portion 22.

[0083] Specifically, such as Figures 1-2 As shown, the reinforcing plate 4 is disposed in the buffer cavity 3, which can ensure the reliability of the front assembly 100. The reinforcing plate 4 is provided with a first sub-segment 41, a second sub-segment 42 and a third sub-segment 43. The first sub-segment 41, the second sub-segment 42 and the third sub-segment 43 are connected sequentially along the front and rear direction of the vehicle, that is, the second sub-segment 42 is bent and connected between the first sub-segment 41 and the third sub-segment 43.

[0084] Furthermore, the first sub-segment 41 and the first lower plate portion 21 can be connected by welding or other means, and the third sub-segment 43 and the second lower plate portion 22 can be connected by welding or other means. The first sub-segment 41 can be configured as a straight plate structure, and the third sub-segment 43 can also be configured as a straight plate structure. This can increase the contact area between the first sub-segment 41 and the first lower plate portion 21, thereby improving the reliability of the connection between the first sub-segment 41 and the first lower plate portion 21, and can also increase the contact area between the third sub-segment 43 and the second lower plate portion 22, thereby improving the reliability of the connection between the third sub-segment 43 and the second lower plate portion 22.

[0085] Furthermore, the second sub-segment 42 is configured as a curved plate, with an included angle between the first lower plate portion 21 and the second lower plate portion 22. The second sub-segment 42 is configured as a curved plate and is bent and connected between the first sub-segment 41 and the third sub-segment 43, which can ensure the reliability of the connection between the first sub-segment 41 and the first lower plate portion 21, as well as the reliability of the connection between the third sub-segment 43 and the second lower plate portion 22. Moreover, when the collision force is transmitted to the upper lower plate 2 of the front bulkhead, it can be transmitted along the upper lower plate 2 of the front bulkhead and the reinforcing plate 4 respectively, thereby reducing the effect and ensuring the reliability of use.

[0086] In addition, in actual installation, the second sub-segment 42 can be spaced apart from the upper lower plate 2 of the front bulkhead, so that a cavity can also be defined between the second sub-segment 42 and the upper lower plate 2 of the front bulkhead, thereby buffering the impact force again, reducing the impact force and improving the reliability of use.

[0087] This utility model also proposes a vehicle.

[0088] The vehicle according to the present invention includes the front bulkhead assembly 100 of any of the above-mentioned claims.

[0089] According to the vehicle of this utility model embodiment, the upper front panel 1 and the lower front panel 2 together define a buffer cavity 3, which can buffer the impact force to reduce the effect of the impact and improve the vehicle's range performance by reducing weight. The first upper panel 11 and the second lower panel 22 are distributed in the first direction, and the second upper panel 12 and the first lower panel 21 are distributed in the second direction, so that the buffer cavity 3 defined by the first upper panel 11, the second upper panel 12, the first lower panel 21 and the second lower panel 22 is a quadrilateral cavity. This weakens the structural strength of the front panel assembly 100, making it easier for the front panel assembly 100 to collapse when subjected to impact force, thereby reducing the reaction force on the pedestrian's head, improving pedestrian protection safety, and having a better effect and wider applicability.
