[0017] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0018] In some embodiments provided in this application, such as Figure 1 As shown, a front bulkhead outer panel includes a front bulkhead body 1, which comprises a first panel, a face shield, and a second panel. The first and second panels are mirror-image positioned with the center line of symmetry along the length of the face shield as the mirror center. The first panel, face shield, and second panel are integrally formed. The front bulkhead body 1 is integrally injection molded from PP (Polypropylene) material. This integrated design combines the traditional first panel, face shield, and second panel into a single front bulkhead assembly, improving assembly efficiency; eliminating visible seams, reducing whistling and rattling issues, optimizing the drag coefficient, and eliminating the front grille, conforming to mainstream electric vehicle aesthetics—clean, simple, technologically advanced, and aesthetically pleasing. A decorative bright strip 2 is snapped onto the lower edge of the outer side of the front bulkhead body 1 along its length. The decorative bright strip 2 has a corrugated cross-section, which enhances the aesthetics and technological feel of the front of the truck and has a reflective effect at night, improving driving safety. It can be removed and replaced by snap-fit, and when there is a minor frontal scratch, the decorative bright strip 2 will be in contact first, reducing damage to the paint of the front body 1.

[0019] like Figure 1 As shown, in another embodiment of this application, the outer surface of the front body 1 includes a first color partition 3 and a second color partition 4. The first color partition 3 is located above the second color partition 4. The first color partition 3 is coated with a high-gloss black paint, and the second color partition 4 is coated with a body-colored paint. A color-separating groove 5 is provided between the first color partition 3 and the second color partition 4. The color-separating groove 5 is V-shaped. The upper part uses high-gloss black, the lower part uses body color, and the middle is separated by a V-shaped color-separating groove 5, which increases the color elements, improves the product's aesthetics, and achieves a unity of aesthetics, installation adaptability, and reliability of the integrated front body 1.

[0020] like Figure 2As shown, a front bulkhead assembly includes an outer front bulkhead panel, which is a front bulkhead body 1. An inner panel assembly is disposed inside the front bulkhead body 1 and welded to the front bulkhead body 1. The inner panel assembly has multiple honeycomb sections, which are evenly distributed on the inner panel assembly. The inner panel assembly includes a first inner panel 6, a second inner panel 7, a third inner panel 8, and a fourth inner panel 9. The first inner panel 6 and the second inner panel 7 are located at the two ends of the front bulkhead body 1 along its length direction, and are symmetrically arranged with respect to the symmetrical centerline of the front bulkhead body 1 along its length direction. The first inner panel 6 is arranged along the edge contour of the front bulkhead body 1 and is L-shaped. The third inner panel 8 and the fourth inner panel 9 are located at the two ends of the front bulkhead body 1 along its height direction, and are located between the first inner panel 6 and the second inner panel 7. The third inner panel 8 and the fourth inner panel 9 are both straight plate-like structures. The first inner panel 6, the second inner panel 7, the third inner panel 8, and the fourth inner panel 9 are independently arranged and are positioned relative to the front bulkhead body 1. There is a preset gap 10 between the first inner panel 6 and the third inner panel 8 at the bend of the front body 1; there is a preset gap 10 between the second inner panel 7 and the third inner panel 8 at the bend of the front body 1.

[0021] The arrangement of the first inner panel 6, the second inner panel 7, the third inner panel 8, and the fourth inner panel 9 increases the strength of the front bulkhead assembly. At the same time, it does not affect the ability to absorb and buffer external impact forces when the vehicle collides, thus protecting the vehicle body, occupants, and pedestrians. Furthermore, the first inner panel 6, the second inner panel 7, the third inner panel 8, and the fourth inner panel 9 are independently arranged without any connection, avoiding mutual interference. Moreover, a pre-set gap 10 is left at the bend corner of the front bulkhead body 1, without the design of an inner panel structure, which increases the deformability and enhances the collision buffering capacity.

[0022] In another embodiment of this application, such as Figure 2 As shown, the front bulkhead 1, the first inner panel 6, the second inner panel 7, the third inner panel 8, and the fourth inner panel 9 are all made of the same PP material to ensure the strength of single-point welding and appearance quality. The first inner panel 6, the second inner panel 7, the third inner panel 8, and the fourth inner panel 9 are all welded to the inside of the front bulkhead 1 by ultrasonic piercing welding. Ultrasonic piercing welding directly penetrates the upper welded body and contacts the lower body, allowing the plastic materials to bond deeply. After multiple tensile tests, its welding strength is significantly higher than that of ordinary ultrasonic welding. The impact on the product appearance is controllable, avoiding bulging defects. No additional consumables are required. High-frequency vibration acts directly on the contact point, the welding time is short, and it is suitable for mass production. The welding parameters can be controlled by computer program, and with the help of positioning tooling, unattended operation can be achieved, improving production efficiency.

[0023] The front bulkhead 1 is connected to the body via D-type clips and bolts. The first inner panel 6, second inner panel 7, third inner panel 8, and fourth inner panel 9 are connected to the body via A-type clips, ensuring component strength, installation reliability, and aesthetic appearance. The diameter of the mating holes at the mounting points of the D-type clips and bolts is larger than the diameter of the mating holes at the mounting points of the A-type clips, absorbing welding tolerances during the welding process of the left and right side bulkheads and the front bulkhead of the body-in-white, ensuring a smooth installation process between the integrated front bulkhead and the body-in-white, and a good fit between the front bulkhead assembly and the appearance of the body-in-white.

[0024] A vehicle includes a front bulkhead outer panel and / or a front bulkhead assembly, wherein the vehicle using the front bulkhead outer panel or the front bulkhead assembly can maintain both aesthetics and strength in a good state, and can ensure maximum safety while maintaining aesthetics.
