[0052] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0053] In the present disclosure, unless otherwise stated, the directional words used are: the first direction is set as the height direction of the vehicle, the second direction is set as the left-right direction of the vehicle, the third direction is set as the front-rear direction of the vehicle, the front refers to the front direction of the vehicle, the rear refers to the rear direction of the vehicle, and "inside and outside" refer to the inside and outside of the relevant parts. In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0054] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0055] With the development of new energy vehicles, automobile lightweighting is the core technology and important development direction of the automobile industry. It refers to reducing the weight of the vehicle without reducing the safety, reliability, comfort and cost of the vehicle, thereby improving the vehicle's power economy and increasing the vehicle's cruising range. Therefore, while lightweighting the vehicle, more attention needs to be paid to the collision safety of the vehicle.

[0056] In the related art, the structural strength of the front panel of the vehicle is not high. When the vehicle is hit, the front panel has a large intrusion, which may cause harm to the passengers in the passenger compartment. In particular, the front panel of the vehicle model without sheet metal flow grooves has a certain reduction in the torsion of the whole vehicle and the stiffness mode of the front panel, which affects the collision safety of the vehicle.

[0057] For this reason, Figure 1-Figure 7 As shown, one aspect of the present disclosure provides a dash panel assembly, including a dash panel body 1, a mounting plate 2, and two dash panel pillars 3 that are spaced apart.

[0058] The two dash panel pillars 3 extend along a first direction and are connected to one side of the dash panel body 1 . The mounting plate 2 extends along a second direction and both ends of the mounting plate 2 are connected to the two dash panel pillars 3 , respectively.

[0059] The first direction and the second direction are arranged at an angle. The mounting plate 2 can be a front wheel housing support rod mounting plate 2 .

[0060] In the above technical solution, two spaced-apart dash panel pillars 3 are connected to the dash panel body 1, and the mounting plate 2 is connected to the two dash panel pillars 3, and the mounting plate 2 is arranged at an angle to the extension direction of the dash panel pillars 3, so as to form a reinforcement structure, and the overall strength of the dash panel body 1 can be enhanced, so that when the vehicle is hit, the dash panel body 1 can withstand more force, effectively protecting the safety of the passengers in the passenger compartment, and at the same time, it can also greatly improve the torsional stiffness of the whole vehicle and improve the structural strength of the whole vehicle.

[0061] It should be noted that the design of the front panel assembly can be applied to vehicles without a sheet metal water flow channel structure, which can well protect the passenger compartment. Of course, it can also be applied to vehicles with a sheet metal water flow channel structure. It can also effectively enhance the overall strength of the front panel body 1, reduce the intrusion amount of the front panel body 1, and effectively protect the safety of the members.

[0062] like Figure 2 As shown, optionally, in one embodiment of the present disclosure, the two ends of the mounting plate 2 in the second direction are respectively connected to the middle parts of the two front panel pillars 3 in the first direction, wherein the first direction and the second direction are perpendicular to each other. By such an arrangement, the mounting plate 2 and the two front panel pillars 3 can form an H-shaped structure, which can further improve the overall strength of the front panel body 1.

[0063] Optionally, in another embodiment of the present disclosure, the two ends of the mounting plate 2 in the second direction are respectively connected to the top or bottom of the two front panel pillars 3 in the first direction, wherein the first direction and the second direction are perpendicular to each other. By such an arrangement, the mounting plate 2 and the two front panel pillars 3 can form a U-shaped structure, and the overall strength of the front panel body 1 can also be improved. Of course, the first direction and the second direction can also be at other angles, such as 30°, 45°, etc., that is, the front panel pillars 3 can be arranged at an angle.

[0064] Optionally, in one embodiment of the present disclosure, the dash assembly further includes a windshield lower cross beam 4, which is connected to the top of the dash body 1, the tops of the two dash pillars 3 extend toward the top of the dash body 1 and are close to the top of the dash body 1, and the mounting plate 2, the two dash pillars 3 and the windshield lower cross beam 4 together enclose a first annular frame structure. By extending the tops of the two dash pillars 3 to the top of the dash body 1 and connecting the top of the dash body 1 with the windshield lower cross beam 4, the tops of the two dash pillars 3 and the windshield lower cross beam 4 can be indirectly connected, so that the entire upper structure of the dash assembly forms a whole, thereby improving the integrity and overall structural strength. In addition, the mounting plate 2, two front panel pillars 3 and the front windshield lower cross beam 4 together form a first annular frame structure, which can make the overall strength and modality of the front panel assembly higher, further ensuring that when the vehicle is subjected to a head-on collision, the intrusion into the passenger compartment is lower, effectively reducing the risk of injury to passengers caused by the collision and ensuring the safety of passengers.

[0065] In some examples, a seventh flange extending along a third direction is formed on the top of the front panel body 1, a sixth flange extending along the third direction is formed on the bottom of the front windshield lower cross beam 4, and the seventh flange and the sixth flange are attached and welded together.

By extending the bottoms of the two dash panel columns 3 to the bottom of the dash panel body 1 and connecting the top of the dash panel body 1 to the front windshield lower cross beam 4, the entire lower structure of the dash panel assembly can be formed into a whole, thereby improving the integrity and overall structural strength. In addition, the mounting plate 2, two dash panel uprights 3 and dash panel lower cross beam assembly 5 together enclose a second ring frame structure, which can make the overall strength and modality of the dash panel assembly higher, further ensuring that when the vehicle is hit head-on, the intrusion into the passenger compartment is lower, effectively reducing the risk of injury to passengers caused by the collision, and ensuring the safety of passengers. Moreover, the combination of the first ring frame structure and the second ring frame structure forms a double ring structure, which can better improve the overall strength and modality of the dash panel assembly. In some examples, the top of the dash panel lower cross beam assembly 5 is welded to the bottom of the dash panel body 1.

The first flange 62 and the second flange 63 are provided at the notch of the groove. The first flange 62 is attached to the dash pillar 3 and welded to a portion of the dash pillar 3 to achieve connection in the third direction. The second flange 63 is attached to a portion of the surface of the dash lower cross beam assembly 5 and is welded and fixed. In some examples, the first flange 62 extends along the second direction.
