DETAILED DESCRIPTION

[0020] Embodiments of the present application are described below in detail with reference to the drawings, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0021] In combination Figure 1 And Figure 2 According to the vehicle body front structure 10 of the embodiment of the present application, the front longitudinal wheel cover 12 and the under dash cross beam 11 are provided in a split structure, and the front longitudinal wheel cover 12 is fixedly connected with the under dash cross beam 11. By providing the front longitudinal wheel cover 12 and the under dash cross beam 11 in a split structure, the front longitudinal wheel cover 12 and the under dash cross beam 11 can be respectively manufactured and formed, and then assembled together in the production process of the vehicle body. In this way, when any one of the front longitudinal wheel cover 12 and the under dash cross beam 11 needs to be redesigned or changed, the manufacturing process of the other component does not need to be changed, and the entire vehicle body front structure 10 does not need to be redesigned, thereby reducing the cost in the process of updating and redesigning the vehicle, and improving the degree of freedom of local design of the vehicle body front structure 10. In addition, the adaptability of the vehicle body front structure 10 can be improved, so that the vehicle body front structure 10 can be applied to different vehicle models.

[0022] According to the vehicle body front structure 10 of the embodiment of the present application, the vehicle body front structure 10 is provided in a split structure, which does not increase too much tailor-welding process, and improves the compatibility of the parts. In addition, the design flexibility of each part can be improved, which is helpful to cope with the complex part assembly environment in the engine compartment.

[0023] In addition, in order to further improve the application range of the vehicle body front structure 10, the under dash cross beam 11 and the front longitudinal wheel cover 12 can be provided in a form that the relative position is adjustable. For example, Figure 2 In some embodiments of the present application, the front end of the front longitudinal wheel cover 12 is fixedly connected to the rear side of the under dash cross beam 11, and the position of the front end of the front longitudinal wheel cover 12 relative to the under dash cross beam 11 is adjustable. In this way, when different vehicle models are used, the same manufacturing process can be used to manufacture the under dash cross beam 11 and the front longitudinal wheel cover 12, and then the relative position of the under dash cross beam 11 and the front longitudinal wheel cover 12 is adjusted to adapt to different vehicle models. When the relative position of the under dash cross beam 11 and the front longitudinal wheel cover 12 is adjusted to the appropriate position, the under dash cross beam 11 and the front longitudinal wheel cover 12 are fixedly connected together by fixed connection.

[0024] In the present application, the front longitudinal beam hub can be adjusted in the up-down direction, the front-rear direction, the left-right direction, and the like relative to the lower transverse beam 11 of the front wall. In some embodiments of the present application, the front longitudinal beam hub is mainly described as being adjusted in the up-down direction relative to the lower transverse beam 11 of the front wall, but this is not a limitation on the scope of protection of the present application.

[0025] In some embodiments of the present application, the front end of the front longitudinal beam wheel cover 12 can be adjusted in the up-down direction relative to the lower transverse beam 11 of the front wall. Thus, the position of the front longitudinal beam wheel cover 12 in the up-down direction can be adjusted. In this case, a first abutting surface can be provided at the front end of the front longitudinal beam wheel cover 12, and the rear side of the lower transverse beam 11 of the front wall has a second abutting surface. The first abutting surface and the second abutting surface abut in the front-rear direction, and both the first abutting surface and the second abutting surface are flat surfaces, so that the first abutting surface is adjustable in the up-down direction relative to the second abutting surface. In this way, not only can the front end of the front longitudinal beam wheel cover 12 be adjusted in the up-down direction relative to the lower transverse beam 11 of the front wall, but also the front longitudinal beam wheel cover 12 can be translated in the up-down direction during adjustment. Moreover, since the first abutting surface and the second abutting surface are flat surfaces that can abut each other, the front longitudinal beam wheel cover 12 can be fixedly connected to the lower transverse beam 11 of the front wall at multiple positions, and the requirements of the front body structure 10 on structural strength can be met.

[0026] In some embodiments of the present application, one of the front longitudinal beam wheel cover 12 and the lower transverse beam 11 of the front wall is provided with a receiving groove 104, and the other is adjustably embedded in the receiving groove 104 in the up-down direction. Specifically, the receiving groove 104 can be provided on the front longitudinal beam wheel cover 12, and the lower transverse beam 11 of the front wall is embedded in the receiving groove 104. Alternatively, the receiving groove 104 can be provided on the lower transverse beam 11 of the front wall, and the front longitudinal beam wheel cover 12 is embedded in the receiving groove 104. Through the design of the mutual embedding of the front longitudinal beam wheel cover 12 and the lower transverse beam 11 of the front wall, the connection strength between the front longitudinal beam wheel cover 12 and the lower transverse beam 11 of the front wall can be effectively improved, thereby improving the structural strength of the front body structure 10.

[0027] Optionally, in combination with Figure 1 and Figure 2 , the receiving groove 104 is provided on the front longitudinal beam wheel cover 12, and the end of the lower transverse beam 11 of the front wall is embedded in the receiving groove 104. In this way, during assembly, a portion of the lower transverse beam 11 of the front wall can be embedded in the receiving groove 104, thereby effectively increasing the fitting area between the lower transverse beam 11 of the front wall and the front longitudinal beam wheel cover 12, and further improving the structural strength of the front body structure 10.

[0028] Further, as Figure 2As shown, the accommodating groove 104 is a through groove penetrating from top to bottom, the end of the front wall lower cross beam 11 has an end surface 101, an inclined surface 102 and a rear surface 103, the inclined surface 102 is connected between the end surface 101 and the rear surface 103, and the inclined surface 102 is inclined relative to the rear surface 103 and the end surface 101, the inclined surface 102 overlaps with the bottom surface 105 of the accommodating groove 104, and the end surface 101 and the rear surface 103 respectively overlap with the left and right side surfaces of the accommodating groove 104. Therefore, the connection strength between the front wall lower cross beam 11 and the front longitudinal beam wheel cover 12 can be further improved.

[0029] In addition, the bottom surface 105 and the left and right side surfaces of the accommodating groove 104 can be vertical surfaces extending in the up-down direction. In this way, the end of the front wall lower cross beam 11 can be smoothly moved in the accommodating groove 104 in the up-down direction to meet the purpose of adjusting the relative position between the front wall lower cross beam 11 and the front longitudinal beam wheel cover 12. Moreover, the front wall lower cross beam 11 and the front longitudinal beam wheel cover 12 can be effectively matched at multiple positions to maintain high structural strength and good stability of the vehicle body front structure 10 in different vehicle models.

[0030] Alternatively, the front end of the front longitudinal beam wheel cover 12 is connected or welded to the front wall lower cross beam 11 by a fixing member. The front end of the front longitudinal beam wheel cover 12 and the front wall lower cross beam 11 can be fixedly connected by bolts, rivets, structural glue, self-piercing rivets, flow-drilling self-tapping screws, etc. Different connection methods can be used according to actual needs. Of course, the front end of the front longitudinal beam wheel cover 12 and the front wall lower cross beam 11 can also be fixedly connected by welding, etc. to further improve the structural strength and optimize the production efficiency.

[0031] In addition, in some embodiments of the present application, the left and right ends of the front wall lower cross beam 11 are connected with the front longitudinal beam wheel covers 12.
