[0023] See also Figure 1 to Figure 2 As shown, the front wall assembly 1 includes a front wall outer panel 2 and a front wall inner panel 3, the front wall outer panel 2 and the front wall inner panel 3 are fixedly connected, and the front wall outer panel 2 and the front wall inner panel 3 are respectively stamped and formed in one piece.

[0024] The front panel outer panel 2 and the front panel inner panel 3 are respectively stamped integrally, which reduces the number of parts compared to welding and fixing multiple parts together, and the structure of the front panel assembly 1 is simple, which reduces the production management cost; at the same time, the strength of the front panel assembly 1 is improved; furthermore, the aesthetics of the front panel assembly 1 is improved, the assembly convenience of the surrounding assembly parts is improved, and the collision strength of the front panel assembly 1 is improved.

[0025] The front enclosure outer panel 2 and the front enclosure inner panel 3 form a double-layer composite structure, which improves the overall rigidity of the front enclosure assembly 1. Under the action of external forces, the force can be well transmitted from the front enclosure assembly 1 to the side enclosure assembly or floor assembly of the vehicle, thereby preventing the front enclosure assembly 1 from causing a large force on the cab. The front enclosure outer panel 2 and the front enclosure inner panel 3 form a chamber 11, which enables the vehicle to have a stronger ability to absorb collisions and reduce damage to passengers and drivers.

[0026] Optionally, both sides of the double-layer composite structure of the dash outer panel 2 and the dash inner panel 3 bulge outward to form a cavity 11 .

[0027] In some embodiments, the front enclosure outer panel 2 and the front enclosure inner panel 3 are connected by welding, and a closed chamber 11 is formed between the front enclosure outer panel 2 and the front enclosure inner panel 3, thereby improving the lateral and vertical stiffness of the front enclosure assembly.

[0028] In addition, in some embodiments, the dash outer panel 2 and the dash inner panel 3 may also be connected by bolts.

[0029] like Figure 2 As shown, the front outer panel 2 includes a pair of front outer panels 22 and a front outer panel upper cross beam 21 and a front outer panel lower cross beam 23 connecting the pair of front outer panels. The pair of front outer panels 22, the front outer panel upper cross beam 21 and the front outer panel lower cross beam 23 form a first vent 71.

[0030] Optionally, the dash outer panel 2 is formed by integrally stamping sheet metal through a mold; when the front panel of the vehicle is opened, the dash assembly 1 is the area that is directly seen, and the dash outer panel 2 has a small number of parts, thereby improving the aesthetics of the vehicle dash assembly 1.

[0031] The front inner panel 3 includes a pair of front inner side panels 32 and a front inner panel upper cross beam 31 and a front inner panel lower cross beam 33 connecting the pair of front inner side panels 32. The pair of front inner side panels 32, the front inner panel cross beam 31 and the front inner panel lower cross beam 33 form a second vent 72. After the cross beam 21 on the front outer panel and the cross beam 31 on the front inner panel are fixed, the first vent 71 is connected to the second vent 72.

[0032] Optionally, the dash inner panel 3 is formed by integrally stamping sheet metal through a mold, with a small number of parts and a higher aesthetics of the dash assembly 1.

[0033] See also Figure 2 and Figure 3 The cross beam 21 on the front wall outer plate is fixed to the cross beam 31 on the front wall inner plate, and the cross beam 21 on the front wall outer plate and the cross beam 31 on the front wall inner plate together form a first cavity 4, and the cavity 11 includes the first cavity 4.

[0034] The cross beam 21 on the front enclosure outer plate is connected to the cross beam 31 on the front enclosure inner plate to form an upper cross beam 8 .

[0035] See also Figure 2 and Figure 4 The front enclosure outer panel 22 is fixed to the front enclosure inner panel 32, and the front enclosure outer panel 22 and the front enclosure inner panel 32 together form a second chamber 5. The chamber 11 includes the second chamber 5. The second chamber 5 improves the stiffness of the front enclosure outer panel 22 and the front enclosure inner panel 32. In the case of a head-on collision of the vehicle, the stiffness of the front enclosure assembly 1 is higher and the energy absorption space of the front body of the vehicle is larger.

[0036] like Figure 1 and Figure 2 As shown, after the front enclosure outer panel 2 and the front enclosure inner panel 3 are fixed, the front enclosure outer panel 22 is aligned with the front enclosure inner panel 32, and the first vent 71 is aligned with the second vent 72; the first vent 71 and the second vent 72 are combined to form the vent 7, and the vent 7 is arranged in the middle of the front enclosure assembly 1.

[0037] A pair of front enclosure outer panels 22 are symmetrically arranged relative to the central axis of the front enclosure outer panel 2, and a pair of front enclosure inner panels 32 are symmetrically arranged relative to the central axis of the front enclosure inner panel 3. The overall front enclosure assembly 1 adopts a roughly symmetrical design on the left and right, which not only improves the aesthetics, but also takes into account the needs of right-hand drive vehicle development and can be switched at low cost.
