For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0048] Reference below Figures 1-6 The dash assembly 100 according to an embodiment of the present invention can increase the conduction path of the force to improve the transmission efficiency of the force, improve the safety of the vehicle, and improve the NVH performance of the vehicle to ensure the user's comfort.

[0049] like Figures 1-6 As shown, a dash assembly 100 according to one embodiment of the present invention includes: a dash top rail 1 , an A-pillar structure 3 and a lower A-pillar structure 4 .

[0050] The front upper side beam 1 is extended from bottom to top along the front-to-back direction, and is inclined outward along the front-to-back direction. The front portion of the A-pillar structure 3 is connected to the rear portion of the front upper side beam 1, and the A-pillar structure 3 is constructed to extend from bottom to top along the front-to-back direction relative to the rear portion of the front upper side beam 1. The lower A-pillar structure 4 is extended in the vertical direction, and the upper end of the lower A-pillar structure 4 is connected to the rear portion of the front upper side beam 1.

[0051] Among them, the front panel assembly 100 is arranged at the front of the vehicle and can be connected between the front bumper and the passenger compartment of the vehicle to transmit the force, and the effect of the force can be weakened during the transmission process to avoid the front of the vehicle from invading the passenger compartment and improve safety of use.

[0052] Specifically, the front panel assembly 100 is provided with a front panel upper side beam 1, which extends along the front and rear directions of the vehicle. The front part of the front panel upper side beam 1 can be connected to the energy absorption box 8 through the adapter 7, and the front part of the energy absorption box 8 is connected to the front bumper, that is, when a collision occurs at the front of the vehicle, the collision force can be transmitted to the energy absorption box 8 to be weakened, and then transmitted rearward to the front panel upper side beam 1 through the energy absorption box 8 and the adapter 7. The front panel upper side beam 1 is constructed to be inclined from bottom to top and outward along the front and rear directions, and is inclined outward along the front and rear directions. When the front panel upper side beam 1 is deformed by force, it can be deformed outwardly toward the left and right sides of the vehicle to avoid the front panel upper side beam 1 from intruding into the passenger compartment, thereby improving safety in use. When the vehicle collides from the side, the collision force can also act on the front panel upper side beam 1 first, and then be transmitted through the front panel upper side beam 1, thereby improving safety in use.

[0053] Furthermore, the front panel assembly 100 is also provided with an A-pillar structure 3, which is arranged at the left front and right front of the vehicle and connected between the roof and the front cabin. It is located between the engine compartment and the cockpit, which can improve the structural strength of the front of the vehicle and ensure driving safety. The A-pillar structure 3 is extended in the front-to-back direction, and the front part of the A-pillar structure 3 is connected to the rear part of the front panel upper side beam 1, that is, the force transmitted to the front panel upper side beam 1 can be transmitted to the A-pillar structure 3, and the A-pillar structure 3 is constructed to extend from bottom to top in the front-to-back direction relative to the rear part of the front panel upper side beam 1, that is, the extension direction of the A-pillar structure 3 is different from the extension direction of the front panel upper side beam 1, so that when the force is transmitted from the front panel upper side beam 1 to the A-pillar structure 3, the transmission direction of the force can be changed, thereby weakening the force.

[0054] In addition, the front panel assembly 100 is also provided with a lower A-pillar structure 4, which is configured to extend along the vertical direction of the vehicle. The lower A-pillar structure 4 is located below the front of the A-pillar structure 3, and the upper end of the lower A-pillar structure 4 is connected to the rear of the front panel upper side beam 1, that is, the force transmitted to the front panel upper side beam 1 can be transmitted to the lower A-pillar structure 4, and the extension direction of the lower A-pillar structure 4 is different from the extension direction of the front panel upper side beam 1, so that when the force is transmitted from the front panel upper side beam 1 to the lower A-pillar structure 4, the transmission direction of the force can be changed, thereby weakening the force.

[0055] In this way, the force transmitted to the front dash top rail 1 can be transmitted to the A-pillar structure 3 and the lower A-pillar structure 4, thereby dispersing the force and weakening its effect. This also increases the force transmission path, improving the efficiency of force transmission and enhancing vehicle safety. Furthermore, when the vehicle travels on bumpy roads, the vibration force can be transmitted along the front dash top rail 1, the A-pillar structure 3, and the lower A-pillar structure 4, further weakening the vibration force, improving the vehicle's NVH performance and ensuring user comfort.

[0056] According to the front panel assembly 100 of the embodiment of the present invention, by connecting the rear part of the front panel upper side beam 1 and the front part of the A-pillar structure 3, and connecting the rear part of the front panel upper side beam 1 and the upper end of the lower A-pillar structure 4, the force can be transmitted to the A-pillar structure 3 and the lower A-pillar structure 4 respectively through the front panel upper side beam 1, so as to increase the conduction path of the force, improve the conduction efficiency, and weaken the effect of the force during the conduction process, so as to improve the safety of the vehicle, and improve the NVH performance of the vehicle, ensure the user's comfort, and have better use effect and a wider range of applications.

[0058] Specifically, the A-pillar structure 3 is located between the engine compartment and the cockpit, and can support and protect the cockpit. Figure 2 and Figure 3 As shown, a first internal cavity 34 is formed inside the A-pillar structure 3. The first internal cavity 34 can be arranged along the extension direction of the A-pillar structure 3, that is, the first internal cavity 34 is formed inside the entire A-pillar structure 3, thereby improving the overall structural strength of the A-pillar structure 3. When the force is transmitted to the A-pillar structure 3, the first internal cavity 34 can weaken the force to improve the reliability of the A-pillar structure 3.

[0059] Furthermore, an A-pillar inner tube beam 35 is also provided in the first internal cavity 34. The A-pillar inner tube beam 35 is constructed as a tubular structure and can be fixed to the inner wall of the first internal cavity 34 by welding or other means. The A-pillar inner tube beam 35 is extended along the length direction of the A-pillar structure 3, so that the A-pillar inner tube beam 35 is provided at various locations along the length of the A-pillar structure 3, thereby improving the structural strength of the A-pillar structure 3, thereby improving the reliability of the A-pillar structure 3, and allowing the acting force to be transmitted jointly through the A-pillar structure 3 and the A-pillar inner tube beam 35 to disperse the acting force and improve safety in use.

[0060] In other embodiments, a second internal cavity 43 is formed in the lower A-pillar structure 4 . An A-pillar lower tube beam 44 is disposed in the second internal cavity 43 . The A-pillar lower tube beam 44 extends along the length direction of the lower A-pillar structure 4 .

[0061] Specifically, the lower A-pillar structure 4 is connected to the lower part of the A-pillar structure 3 and can support the A-pillar structure 3. Figure 2 and Figure 4 As shown, a second internal cavity 43 is formed inside the lower A-pillar structure 4. The second internal cavity 43 can be arranged along the extension direction of the lower A-pillar structure 4, that is, the second internal cavity 43 is formed inside the entire lower A-pillar structure 4, thereby improving the overall structural strength of the lower A-pillar structure 4, and when the force is transmitted to the lower A-pillar structure 4, the second internal cavity 43 can weaken the force to improve the reliability of the lower A-pillar structure 4.

[0062] Furthermore, an A-pillar lower tube beam 44 is also provided in the second internal cavity 43. The A-pillar lower tube beam 44 is constructed as a tubular structure and can be installed in the second internal cavity 43 by means of a connector 45. The A-pillar lower tube beam 44 extends along the length direction of the lower A-pillar structure 4, so that the lower A-pillar structure 4 is provided with an A-pillar lower tube beam 44 at various locations along the length, thereby improving the structural strength of the lower A-pillar structure 4, thereby improving the reliability of the lower A-pillar structure 4, and allowing the acting force to be transmitted jointly through the lower A-pillar structure 4 and the A-pillar lower tube beam 44 to disperse the acting force and improve safety in use.

[0063] In some embodiments, the A-pillar structure 3 includes a first side panel outer panel 31 , a first side panel reinforcement panel 32 and a first A-pillar inner panel 33 . The first side panel outer panel 31 is connected to the outer side of the first side panel reinforcement panel 32 . The first A-pillar inner panel 33 and the first side panel reinforcement panel 32 are connected to jointly define a first internal cavity 34 .

[0064] Specifically, if Figure 3 As shown, the A-pillar structure 3 is provided with a first side panel outer panel 31, a first side panel reinforcement panel 32 and a first A-pillar inner panel 33. The first side panel outer panel 31 is provided on the outer side of the A-pillar structure 3, the first A-pillar inner panel 33 is provided on the inner side of the A-pillar structure 3, and the first side panel reinforcement panel 32 is provided between the first side panel outer panel 31 and the first A-pillar inner panel 33. The first A-pillar inner panel 33 and the first side panel reinforcement panel 32 can jointly define a first internal cavity 34, and a buffer gap is also formed between the first side panel reinforcement panel 32 and the first side panel outer panel 31, thereby improving the structural strength of the A-pillar structure 3 close to the outer side of the vehicle body, thereby improving the reliability of the A-pillar structure 3, and the first side panel outer panel 31 and the first A-pillar inner panel 33 can be connected to both sides of the first side panel reinforcement panel 32 by welding or the like, which can improve the structural strength of the first side panel reinforcement panel 32 to ensure connection reliability.

[0065] In some other embodiments, the lower A-pillar structure 4 includes a second side panel reinforcement panel 41 and a second A-pillar inner panel 42 . The second A-pillar inner panel 42 and the second side panel reinforcement panel 41 are connected to jointly define a second inner cavity 43 .

[0066] Specifically, if Figure 4 As shown, the lower A-pillar structure 4 is provided with a second side reinforcement plate 41 and a second A-pillar inner plate 42. The second side reinforcement plate 41 is provided on the outer side of the lower A-pillar structure 4, and the second A-pillar inner plate 42 is provided on the inner side of the lower A-pillar structure 4. The second A-pillar inner plate 42 and the second side reinforcement plate 41 can jointly define a second internal cavity 43. The second side reinforcement plate 41 can improve the structural strength of the side of the lower A-pillar structure 4 close to the outer side of the vehicle body to improve the reliability of the lower A-pillar structure 4. The second A-pillar inner plate 42 can be connected to the second side reinforcement plate 41 by welding or the like to ensure connection reliability. The second A-pillar inner plate 42 can also be connected to the front panel 6 to increase the force conduction path, thereby weakening the effect of the force.

[0067] In some embodiments, the A-pillar inner tube beam 35 is connected to the inner surface of the first side reinforcement panel 32 and is at least partially spaced apart from the A-pillar inner panel.

[0068] Specifically, the first side panel reinforcement plate 32 is installed between the first side panel outer panel 31 and the first A-pillar inner panel 33, and the first side panel reinforcement plate 32 and the first A-pillar inner panel 33 jointly define a first internal cavity 34. Figure 3 As shown, the A-pillar inner tube beam 35 is installed in the first internal cavity 34 and is connected to the inner surface of the first side panel reinforcement plate 32 through double welding. The double welding has high efficiency, high welding joint strength, good crack resistance, small welding deformation, strong adaptability, and easy operation. It can improve the connection reliability between the A-pillar inner tube beam 35 and the first side panel reinforcement plate 32, and further improve the structural strength of the first side panel reinforcement plate 32 to ensure the overall structural strength of the A-pillar structure 3 and improve safety in use.

Figure 4As shown, the A-pillar lower tube beam 44 can be connected to the second side reinforcement plate 41 and the second A-pillar inner plate 42 respectively through the connecting parts 45. The A-pillar lower tube beam 44 can be provided with multiple threaded tubes by welding or the like, and the connecting parts 45 can be provided as bolts. When the A-pillar lower tube beam 44 is placed in the second internal cavity 43, the second side reinforcement plate 41 and the second A-pillar inner plate 42 can be penetrated by bolts to be screwed and fixed with the threaded tubes provided on the A-pillar lower tube beam 44 to install the A-pillar lower tube beam 44. The installation is convenient and convenient for later maintenance.

[0071] The A-pillar lower tube beam 44 is spaced apart from the second A-pillar inner panel 42 and the second side panel reinforcement plate 41, respectively. That is, the A-pillar lower tube beam 44 is completely spaced apart from the second A-pillar inner panel 42, and the A-pillar lower tube beam 44 is completely spaced apart from the second side panel reinforcement plate 41, so that a buffer gap can be formed between the A-pillar lower tube beam 44 and the second A-pillar inner panel 42 and the second side panel reinforcement plate 41, thereby weakening the effect of the acting force and improving the reliability of the lower A-pillar structure 4.

Figure 3 As shown, the length of the cross-section of the A-pillar inner tubular beam 35 in the front-to-rear direction is set to y, and satisfies: 32mm≤y≤34mm, that is, the length y of the cross-section of the A-pillar inner tubular beam 35 in the front-to-rear direction can be set to 32mm, 32.2mm, 32.4mm, 32.6mm, 32.8mm, 33mm, 33.2mm, 33.4mm, 33.6mm, 33.8mm, 34mm, or other values between 32mm and 34mm. In this embodiment, the length y of the cross-section of the A-pillar inner tubular beam 35 in the front-to-rear direction is set to 33mm.

[0080] In this way, the length L1 of the A-pillar inner tubular beam 35 in the front-to-rear direction is set to satisfy: 1175mm≤L1≤1195mm, and the length L2 of the A-pillar inner tubular beam 35 in the up-down direction is set to satisfy: 585mm≤L2≤605mm. This can prevent the A-pillar structure 3 from being too long, resulting in a longer vehicle body, and can also prevent the A-pillar inner tubular beam 35 from being too short, resulting in the failure to structurally strengthen the entire A-pillar structure 3. This can ensure that the size of the A-pillar structure 3 meets the overall vehicle layout requirements and can also ensure the overall structural strength of the A-pillar structure 3.

[0081] In addition, the length x of the cross-section of the A-pillar inner tubular beam 35 in the left-right direction is set to satisfy: 35mm≤x≤37mm, and the length y of the cross-section of the A-pillar inner tubular beam 35 in the front-back direction is set to satisfy: 32mm≤y≤34mm. This can avoid the cross-section of the A-pillar inner tubular beam 35 being too small, resulting in insufficient structural strength of the A-pillar inner tubular beam 35, and can also avoid the cross-section of the A-pillar inner tubular beam 35 being too large, resulting in a heavy mass of the A-pillar inner tubular beam 35. The structural strength of the A-pillar inner tubular beam 35 can be ensured to ensure the reliability of the A-pillar inner tubular beam 35, and can also avoid the heavy mass of the A-pillar inner tubular beam 35, thereby improving the lightweighting of the entire vehicle.

[0082] In some embodiments, the A-pillar inner tube beam 35 is constructed as a thermally expanded tube or a hydraulically expanded tube beam.

[0083] Specifically, the A-pillar inner tube beam 35 is arranged in the A-pillar structure 3, which can improve the structural strength of the A-pillar structure 3 and ensure the reliability of the A-pillar structure 3. The A-pillar inner tube beam 35 is constructed as a hot air expansion tube or a hydraulic tube beam, that is, the A-pillar inner tube beam 35 can be made by a hot air expansion tube process or a hydraulic process. The hot air expansion tube process has high strength and light weight, which can ensure the reliability of the A-pillar inner tube beam 35 and improve the lightweight of the entire vehicle. The hydraulic process has high manufacturing efficiency and precision, and can reduce the manufacturing cost of the A-pillar inner tube beam 35. In this way, it can be selected according to actual production needs to improve the setting flexibility.

[0084] In other embodiments, the A-pillar lower tube beam 44 is constructed as a rolled tube beam or a hydraulic tube beam.

[0085] Specifically, the A-pillar lower tube beam 44 is arranged in the lower A-pillar structure 4, which can improve the structural strength of the lower A-pillar structure 4 and ensure the reliability of the lower A-pillar structure 4. The A-pillar lower tube beam 44 is constructed as a rolled tube beam or a hydraulic tube beam, that is, the A-pillar lower tube beam 44 can be made by a rolling process or a hydraulic process. The rolling process has high production efficiency, can save materials, and reduce manufacturing costs, and has high strength and stable quality, which can ensure the reliability of the A-pillar lower tube beam 44. The hydraulic process has high manufacturing efficiency and precision, and can reduce the manufacturing cost of the A-pillar lower tube beam 44. In this way, it can be selected according to actual production needs to improve the setting flexibility.

[0086] In some embodiments, the front panel assembly 100 also includes a side panel connecting plate assembly 2, which is extended in the front and rear directions. The front portion of the side panel connecting plate assembly 2 is connected to the rear portion of the front panel upper side beam 1, and the side panel connecting plate assembly 2 is respectively connected to the A-pillar structure 3 and the lower A-pillar structure 4.

[0087] Specifically, if Figure 1-Figure 2 As shown, the front panel assembly 100 is also provided with a side panel connecting plate assembly 2, which is arranged to extend along the front and rear directions of the vehicle. The rear portion of the front panel upper side beam 1 can be connected to the side panel connecting plate assembly 2 by welding or connecting parts, and the side panel connecting plate assembly 2 and the rear portion of the front panel upper side beam 1 at least partially overlap, thereby improving the structural strength of the rear portion of the front panel upper side beam 1 and ensuring the reliability of the front panel upper side beam 1.

[0088] Furthermore, the front portion of the side panel connecting plate assembly 2 is connected to the rear portion of the front panel upper side beam 1, so that the force can be transmitted to the side panel connecting plate assembly 2 through the front panel upper side beam 1, and the side panel connecting plate assembly 2 is respectively connected to the A-pillar structure 3 and the lower A-pillar structure 4, that is, the side panel connecting plate assembly 2 can be connected to the A-pillar structure 3 by welding or the like, and at the same time, it can also be connected to the lower A-pillar structure 4 by welding or the like, so that the force transmitted to the side panel connecting plate assembly 2 can be transmitted toward the A-pillar structure 3 and the lower A-pillar structure 4, respectively, thereby weakening the effect of the force and increasing the conduction path of the force to improve the conduction efficiency of the force and ensure the reliability of the force conduction.

[0089] In some embodiments, the extension direction of the side panel connecting plate assembly 2 is the same as the extension direction of the rear part of the front upper side beam 1, wherein the angle between the extension direction of the side panel connecting plate assembly 2 and the extension direction of the A-pillar structure 3 is set to a, and satisfies: 135°≤a≤150°.

[0090] Specifically, the side panel connecting plate assembly 2 is connected to the rear portion of the front panel upper side beam 1, and the extension direction of the side panel connecting plate assembly 2 is the same as the extension direction of the rear portion of the front panel upper side beam 1, that is, the side panel connecting plate assembly 2 is configured to extend along the front and rear direction of the vehicle, and the rear portion of the front panel upper side beam 1 is also configured to extend along the front and rear direction of the vehicle, so that when the force is transmitted from the front panel upper side beam 1 to the side panel connecting plate assembly 2, the transmission direction of the force remains unchanged, thereby avoiding the force acting on the connection between the side panel connecting plate assembly 2 and the front panel upper side beam 1, so as to ensure the connection reliability of the side panel connecting plate assembly 2 and the front panel upper side beam 1.

[0091] Furthermore, the extension direction of the side panel assembly 2 is different from the extension direction of the A-pillar structure 3, so that Figure 1As shown, an included angle a is formed between the extension direction of the side panel connecting plate assembly 2 and the extension direction of the A-pillar structure 3, and the following conditions are satisfied: 135°≤a≤150°, that is, the included angle a between the extension direction of the side panel connecting plate assembly 2 and the extension direction of the A-pillar structure 3 can be set to 135°, 137°, 139°, 141°, 143°, 145°, 147°, 149°, 150°, or other angles between 135° and 150°.

[0092] In other embodiments, the angle between the extension direction of the A-pillar structure 3 and the extension direction of the lower A-pillar structure 4 is set to b, and satisfies: 120°≤b≤135°.

[0093] Specifically, the lower A-pillar structure 4 is extended along the vertical direction of the vehicle, and the extending direction of the A-pillar structure 3 is different from the extending direction of the lower A-pillar structure 4, so that Figure 1 As shown, an included angle b is formed between the extension direction of the A-pillar structure 3 and the extension direction of the lower A-pillar structure 4, and satisfies: 120°≤b≤135°, that is, the included angle b between the extension direction of the A-pillar structure 3 and the extension direction of the lower A-pillar structure 4 can be set to 120°, 122°, 124°, 126°, 128°, 130°, 132°, 134°, 135°, or other angles between 120° and 135°.

[0094] In this way, the angle a between the extension direction of the side panel connecting plate assembly 2 and the extension direction of the A-pillar structure 3 is set to satisfy: 135°≤a≤150°, and the angle b between the extension direction of the A-pillar structure 3 and the extension direction of the lower A-pillar structure 4 is set to satisfy: 120°≤b≤135°. This can ensure the comprehensive force transmission efficiency of the force transmitted to the A-pillar structure 3 and the lower A-pillar structure 4 through the side panel connecting plate assembly 2, and can avoid excessive force on the A-pillar structure 3 or excessive force on the lower A-pillar structure 4, thereby ensuring the reliability of the A-pillar structure 3 and the lower A-pillar structure 4.

[0095] In some embodiments, the length of the dash top rail 1 in the front-to-back direction is set to L3 and satisfies the following: 665 mm ≤ L3 ≤ 685 mm.

[0096] Specifically, if Figure 5 As shown, the length of the front upper side beam 1 in the front and rear direction is set to L3, and satisfies: 665mm≤L3≤685mm, that is, the length L3 of the front upper side beam 1 in the front and rear direction can be set to 665mm, 668mm, 670mm, 673mm, 676mm, 679mm, 682mm, 685mm, or other values between 665mm and 685mm. In this embodiment, the length L3 of the front upper side beam 1 in the front and rear direction is set to 675mm.

[0097] In this way, the length L3 of the front upper side beam 1 in the front-to-back direction is set to satisfy: 665mm≤L3≤685mm, which can avoid the length of the front upper side beam 1 in the front-to-back direction being too short, resulting in the conduction path of the force being too short, thereby ensuring the effect of weakening the force, and can also avoid the length of the front upper side beam 1 in the front-to-back direction being too long, occupying a large space, thereby ensuring the rationality of the layout between the various structures of the front assembly 100.

[0098] In other embodiments, the length of the dash top rail 1 in the vertical direction is set to L4 and satisfies: 480 mm ≤ L4 ≤ 500 mm.

[0099] Specifically, if Figure 5 As shown, the length of the front upper side beam 1 in the vertical direction is set to L4, and satisfies: 480mm≤L4≤500mm, that is, the length L4 of the front upper side beam 1 in the vertical direction can be set to 480mm, 483mm, 486mm, 489mm, 492mm, 495mm, 498mm, 500mm, or other values between 480mm and 500mm. In this embodiment, the length L4 of the front upper side beam 1 in the vertical direction is set to 491mm.

[0100] In this way, the length L4 of the front upper side beam 1 in the vertical direction is set to meet the following conditions: 480mm≤L4≤500mm, which can avoid the length of the front upper side beam 1 in the vertical direction being too short, resulting in a smaller engine compartment capacity, and ensure that sufficient installation and heat dissipation space is provided for the engine and other mechanisms to ensure the stability of vehicle operation. It can also avoid the length of the front upper side beam 1 in the vertical direction being too long, occupying a large space, and ensure the rationality of the layout between the various structures of the front assembly 100.

[0101] In other embodiments, the length of the dash top rail 1 in the left-right direction is set to L5 and satisfies: 225 mm ≤ L5 ≤ 245 mm.

[0102] Specifically, if Figure 6 As shown, the length of the front upper side beam 1 in the left and right direction is set to L5, and satisfies: 225mm≤L5≤245mm, that is, the length L5 of the front upper side beam 1 in the left and right direction can be set to 225mm, 228mm, 230mm, 233mm, 236mm, 239mm, 242mm, 245mm, or other values between 225mm and 245mm. In this embodiment, the length L5 of the front upper side beam 1 in the left and right direction is set to 235mm.

[0103] In this way, the length L5 of the front upper side beam 1 in the left-right direction is set to satisfy: 225mm≤L5≤245mm, which can prevent the length of the front upper side beam 1 in the left-right direction from being too short, ensure that the front upper side beam 1 can be deformed toward the outside of the vehicle when subjected to collision force, prevent the front upper side beam 1 from invading the passenger compartment, ensure driving safety, and prevent the length of the front upper side beam 1 in the left-right direction from being too long, occupying a large space, and ensure the rationality of the layout between the various structures of the front assembly 100.

[0104] In some embodiments, the front panel assembly 100 also includes a front panel longitudinal beam 5, the front portion of the front panel longitudinal beam 5 and the front portion of the front panel upper side beam 1 are both connected to the energy absorption box 8 through an adapter 7, the front panel longitudinal beam 5 is located below the front panel upper side beam 1, and the rear portion of the front panel longitudinal beam 5 is connected to the lower A-pillar structure 4.

[0105] Specifically, the front panel assembly 100 is arranged at the front of the vehicle, and the rear of the front panel assembly 100 can be connected to the floor of the vehicle, so that when the front of the vehicle collides, the collision force can be transmitted to the floor, etc., thereby improving the safety of the vehicle. Figure 1-Figure 2 As shown, the front panel assembly 100 is also provided with a front panel longitudinal beam 5, which extends along the front and rear directions of the vehicle, and the front portion of the front panel longitudinal beam 5 and the front portion of the front panel upper side beam 1 are connected to the energy absorption box 8 through an adapter 7, and the front panel longitudinal beam 5 is located below the front panel upper side beam 1.

[0106] In this way, when a collision occurs at the front of the vehicle, the collision force acts on the anti-collision beam, and then can be absorbed by the energy absorption box 8, so as to be transmitted to the front panel longitudinal beam 5 and the front panel upper side beam 1 through the energy absorption box 8 and the adapter 7, so that part of the collision force can be transmitted backward through the front panel longitudinal beam 5, and the other part of the collision force can be transmitted backward through the front panel upper side beam 1, thereby increasing the transmission path of the collision force, dispersing the effect of the collision force, and improving the safety of use.

[0107] The rear part of the front panel longitudinal beam 5 is connected to the lower A-pillar structure 4, and the rear part of the front panel upper side beam 1 is connected to the A-pillar structure 3 and the lower A-pillar structure 4 through the side panel connecting plate assembly 2, so that the force transmitted to the front panel longitudinal beam 5 can be transmitted backward through the lower A-pillar structure 4, and the force transmitted to the front panel upper side beam 1 can be transmitted backward through the A-pillar structure 3 and the lower A-pillar structure 4 respectively, thereby dispersing the force to weaken the effect of the force and ensure safety in use.

[0108] In some embodiments, the front panel assembly 100 further includes a chassis suspension, the front portion of the chassis suspension is connected to the adapter 7 , and the rear portion of the chassis suspension is connected to the front panel structure.

[0109] Specifically, if Figure 1-Figure 2As shown, the dash assembly 100 is also equipped with a chassis suspension that extends in the front-to-back direction of the vehicle. The front portion of the chassis suspension, the front portion of the dash top rail 1, and the front portion of the dash longitudinal rail 5 are all connected to the energy box 8 via an adapter 7. Thus, when a front collision occurs, the collision force acts on the anti-collision beam, which is then absorbed by the energy box 8. The energy is then transferred to the chassis suspension through the energy box 8 and the adapter 7, allowing the collision force to be transmitted rearward through the chassis suspension, improving vehicle safety.

[0110] The rear part of the chassis suspension is connected to the front wall structure, the rear part of the front wall longitudinal beam 5 is connected to the lower A-pillar structure 4, and the rear part of the front wall upper side beam 1 is connected to the A-pillar structure 3 and the lower A-pillar structure 4 through the side wall connecting plate assembly 2, so that the force transmitted to the front wall longitudinal beam 5 can be transmitted backward through the lower A-pillar structure 4, the force transmitted to the front wall upper side beam 1 can be transmitted backward through the A-pillar structure 3 and the lower A-pillar structure 4 respectively, and the force transmitted to the chassis suspension can be transmitted backward through the front wall structure, thereby dispersing the force to weaken the effect of the force and ensure safety in use.

[0113] According to the vehicle of the embodiment of the present invention, a front panel assembly 100 is provided, and the front panel assembly 100 connects the rear part of the front panel upper side beam 1 and the front part of the A-pillar structure 3, and connects the rear part of the front panel upper side beam 1 and the upper end of the lower A-pillar structure 4, so that the force can be transmitted to the A-pillar structure 3 and the lower A-pillar structure 4 respectively through the front panel upper side beam 1, so as to increase the conduction path of the force, improve the conduction efficiency, and weaken the effect of the force during the conduction process of the force, so as to improve the safety of the vehicle, and improve the NVH performance of the vehicle, ensure the user's comfort, and have better use effect and a wider range of applications.
