The upper end of the mounting bracket 31 here means an end of the mounting bracket 31 located at an upper portion in the vehicle height direction, and the upper end of the front cabin cross member 2 means an end of the front cabin cross member 2 located at an upper portion in the vehicle height direction. Generally, the vehicle height direction may also be considered as a vertical direction.

Further, the upper end of the mounting bracket 31 and the upper end of the front cabin cross member 2 are located at the same height in the vehicle height direction, and it is considered that the upper end of the mounting bracket 31 and the upper end of the front cabin cross member 2 are located on the same horizontal plane.

In the embodiment of the present application, the size of the mounting bracket 31 or the front cabin cross member 2 may be adjusted so that the upper end of the mounting bracket 31 and the upper end of the front cabin cross member 2 are located at the same height in the vehicle height direction. In addition, the position of the mounting bracket 31 in the vehicle height direction or the position of the front cabin cross member 2 in the vehicle height direction may be adjusted so that the upper end of the mounting bracket 31 and the upper end of the front cabin cross member 2 are located at the same height in the vehicle height direction. Through the above arrangement, the upper end of the mounting bracket 31 and the upper end of the front cabin cross beam 2 are arranged to be located at the same height along the height direction of the vehicle, so that the support member 32 can be conveniently arranged to extend along the horizontal direction, and the storage battery 4 can also be conveniently mounted.

In addition, in other embodiments of the present application, the upper end of the mounting bracket 31 and the upper end of the front cabin cross member 2 may be disposed so as not to be located at the same height in the height direction of the vehicle, for which purpose the support member 32 may be adaptively adjusted, for example, a supplementary pad may be provided on the support member 32 to extend the mounting surface of the support member 32 for mounting the battery 4 in the horizontal direction, so as to facilitate the mounting of the battery 4.

In the following description and in the drawings, the upper end of the mounting bracket 31 and the upper end of the front nacelle cross member 2 are positioned at the same height in the height direction of the vehicle. On the basis, referring to fig. 1 to 4, in some embodiments of the present application, the vehicle front cabin structure further includes a shock tower assembly 5. The shock tower assembly 5 may be used to mount a shock absorber and to withstand the spring forces of the shock absorber, as well as the impacts imparted to the vehicle by the road surface. The shock absorber tower assembly 5 can disperse the shock of the shock absorber to the vehicle by the road surface.

In the embodiment of the present application, the specific structural form of the shock absorber assembly 5 is not limited. For example, referring to fig. 1 and 2, a shock tower assembly 5 may be connected between a front cabin side rail 1 and a front cabin side rail 6.

Further, referring to fig. 2 to 4, in the embodiment of the present application, the shock tower assembly 5 includes a bridge 51, and the bridge 51 is connected to a side of the front cabin rail 1 corresponding to the vehicle interior. And, the bridge 51 is provided between the front cabin rail 1 and the mounting bracket 31. The projections of the bridge piece 51, the front cabin rail 1 and the mounting bracket 31 in the vehicle width direction have overlapping areas in which the bridge piece 51, the front cabin rail 1 and the mounting bracket 31 may be joined together.

In the embodiment of the present application, the specific structure of the bridge 51 is not limited either. For example, referring to fig. 2 to 4, the main body structure of the shock tower assembly 5 is located above the front cabin rail 1, and for this purpose, a connection structure may be provided below the main body structure of the shock tower assembly 5 as a bridge 51 to connect the shock tower assembly 5 to a side of the front cabin rail 1 corresponding to the vehicle interior. More specifically, referring to fig. 2 to 4, a plate-like structure extending in the vertical direction may be provided as the bridge 51.

On this basis, referring to fig. 2 to 4, the disposition of the bridge 51 between the front cabin rail 1 and the mounting bracket 31 means that the bridge 51 is disposed between the front cabin rail 1 and the mounting bracket 31 in the width direction of the vehicle.

The front nacelle cross member 2, the bridge 51, and the mounting bracket 31 may be stacked in the vehicle width direction so that the front nacelle cross member 2, the bridge 51, and the mounting bracket 31 have overlapping regions in the vehicle width direction.

Specifically, the front cabin cross member 2 is generally larger in size in the vehicle longitudinal direction, and for this purpose, the size of the bridge piece 51 in the vehicle longitudinal direction may be set larger than the size of the mounting bracket 31 in the vehicle longitudinal direction. In this way, the bridge 51 can be first mounted on the side of the front cabin rail 1 corresponding to the vehicle interior, and on this basis, it can be ensured that the projections of the bridge 51 and the front cabin rail 1 in the vehicle width direction have overlapping areas.

On this basis, the mounting bracket 31 is again mounted on the bridge piece 51, and by adjusting the position of the mounting bracket 31, it is possible to ensure that the mounting bracket 31 is located in the overlapping region of the above-described projection of the bridge piece 51 and the front cabin side member 1 in the vehicle width direction.

In the above manner, it is possible to ensure that the overlap piece 51, the front cabin rail 1, and the mounting bracket 31 have overlapping areas in the vehicle width direction projection.

On this basis, in the embodiment of the present application, the front cabin rail 1, the bridge piece 51 and the mounting bracket 31 are also fixedly connected together.

For example, one connecting structure may be provided to fixedly connect the bridge piece 51 to the front cabin rail 1, and another connecting structure may be provided to fixedly connect the mounting bracket 31 to the bridge piece 51. In addition, referring to fig. 4 and 5, a connecting structure may be provided to fixedly connect together the front cabin rail 1, the bridge piece 51 and the mounting bracket 31 as a whole.

Thus, by the above arrangement, the mounting bracket 31, the bridge piece 51, and the front cabin rail 1 can be mutually formed into a reinforcing structure, and the vehicle can meet the requirements of the collision class. For example, the requirements of the vehicle that the crashworthiness and maintenance economy index is general, the occupant safety index in the vehicle is excellent, the safety index of the outside pedestrian is excellent, and the auxiliary safety index of the vehicle is excellent can be satisfied.

In addition, in the embodiment of the application, the mounting bracket 31 and the shock absorber assembly 5 are integrally arranged, so that the space in the front cabin of the vehicle can be saved, and more space is reserved for the arrangement of other parts.

Further, referring to fig. 4 and 5, in some embodiments of the present application, the front cabin rail 1, the bridge piece 51, and the mounting bracket 31 may also be coupled together by a fastening assembly 33 using a fastening assembly 33.

It should be noted that, in the embodiment of the present application, the number of the fastening members 33 may be set to be plural. And a plurality of fastening components 33 may be provided in an array arrangement.

In addition, in other embodiments of the present application, the first fastening member 331 may be fixedly attached to the side of the front cabin rail 1 corresponding to the vehicle interior, and the second fastening member 332 may be screwed to the first fastening member 331 through the mounting bracket 31 and the bridge piece 51, so that the mounting bracket 31, the bridge piece 51, and the front cabin rail 1 may be also coupled together.

In addition to this, in other embodiments of the present application, a screw hole may be provided directly at the side of the front cabin rail 1 corresponding to the vehicle interior, and the second fastener 332 may be screwed to the screw hole through the mounting bracket 31 and the bridge piece 51, so that the mounting bracket 31, the bridge piece 51 and the front cabin rail 1 may be coupled together.

On this basis, the structural form of the first fastening member 331 can be selected according to the arrangement position of the first fastening member 331. For example, for disposing the first fastening member 331 on the side of the front cabin rail 1 corresponding to the outside of the vehicle, a nut may be selected as the first fastening member 331.

For the first fastening member 331 to be provided on the side of the front cabin rail 1 corresponding to the vehicle interior, a nut or a blind rivet nut may be selected as the first fastening member 331. For example, for the optional nut, the nut may be welded to the side of the front cabin rail 1 corresponding to the vehicle interior; for the option of the blind rivet nut, a mounting hole may be provided on the side of the front cabin rail 1 corresponding to the vehicle interior, and the blind rivet nut may be mounted in the mounting hole.

Further, bolts may be selected as the second fastening members 332 in the embodiment of the present application, and the second fastening members 332 may be provided in a targeted manner with respect to the arrangement of the first fastening members 331, the front cabin rail 1, the bridge 51, and the mounting bracket 31.

In this way, by connecting the front cabin rail 1, the bridge piece 51 and the mounting bracket 31 together by the fastening assembly 33, the assembly between the front cabin rail 1, the bridge piece 51 and the mounting bracket 31 can be facilitated, and the mounting bracket 31 or the shock absorber tower assembly 5 can be replaced conveniently, so that the maintenance cost of the front cabin structure of the vehicle provided by the embodiment of the application is reduced.

On this basis, referring to fig. 5, in some embodiments of the present application, a first fastener 331 is provided at a side of the front cabin rail 1 corresponding to the vehicle interior. Also, the first fastener 331 includes a protruding portion 3311, and the protruding portion 3311 protrudes from the front cabin rail 1. In response, a recess 511 is provided on the surface of the bridge 51 on the side of the front side member 1, and the protruding portion 3311 is located in the recess 511.

Specifically, in some embodiments of the present application, the first fastener 331 may be selected as a nut, and the nut may be welded to a side of the front cabin cross member 2 corresponding to the vehicle interior. In this case, the entire structure of the nuts protrudes from the front cabin rail 1, and the entire structure of the nuts forms the protruding portion 3311.

Referring to fig. 5, in other embodiments of the present application, the first fastener 331 may be selected as a blind rivet nut, and the blind rivet nut may be divided into a blind rivet deformation portion and a fastening portion. For this purpose, a mounting hole may be provided in the side of the front cabin cross member 2 corresponding to the vehicle interior, a rivet deformation portion of the rivet nut may be mounted in the mounting hole, and a fastening portion of the rivet nut may protrude from the surface of the side of the front cabin cross member 2 corresponding to the vehicle interior. Thus, the fastening portion of the blind rivet nut forms the protruding portion 3311.

In addition, referring to fig. 5, a recess 511 may be provided on the surface of the bridge 51 on the side closer to the front side member 1, and the protrusion 3311 may be formed to be recessed by the recess 511 by providing the protrusion 3311 in the recess 511.

For example, referring to fig. 5, in the case where a through hole is provided in the bridge 51 to mount the fastener, the above-described relief recess 511 may be formed by providing a variable diameter portion having a larger size on the variable surface of the bridge 51 on the side close to the front cabin longitudinal member 1. With reference to fig. 5, the side of the bridge 51 closer to the front side member 1 can be brought into contact with the side of the front side member 1 corresponding to the vehicle interior by adjusting the depth of the recess 511.

Specifically, the depth of the avoidance concave 511 may be set to be greater than or equal to the height of the protruding portion 3311, so that the side of the bridge 51 near the front cabin rail 1 can be abutted to the side of the front cabin rail 1 corresponding to the vehicle interior.

Here, the depth of the relief recess 511 means the dimension of the relief recess 511 in the vehicle width direction, and the height of the protruding portion 3311 means the dimension of the protruding portion 3311 in the vehicle width direction.

Thus, by the above arrangement, the protruding portion 3311 of the first fastener 331 can be formed to be recessed by the recessed portion 511, and the side of the bridge 51 close to the front cabin side member 1 can be abutted against the side of the front cabin side member 1 corresponding to the vehicle interior, so that the contact area between the front cabin side member 1 and the abutment can be increased, the stress between the front cabin side member 1 and the abutment can be reduced, and the reinforcing effect between the front cabin side member 1 and the bridge 51 can be improved.

Specifically, by providing the bridge 51 with the escape recess 511, the side of the bridge 51 near the front cabin cross member 2 can be brought into abutment with the side of the front cabin side member 1 corresponding to the vehicle interior. Compared to the case where the recess 511 is not provided, the attachment between the bridge 51 and the front cabin rail 1 can be performed, and the contact area between the bridge 51 and the front cabin rail 1 can be increased, so that the stability of the connection between the bridge 51 and the front cabin rail 1 can be improved. In addition, by providing the protruding portion 3311 on the first fastening member 331, the first fastening member 331 can be fixedly connected to the front cabin rail 1 by the protruding portion 3311, for example, for the first fastening member 331 in the embodiment of the application using the clinch nut described above, the portion of the deformed portion of the clinch nut protruding from the front cabin rail 1 can be regarded as the protruding portion 3311; in addition, a general nut may be selected as the first fastening member 331 in the embodiment of the present application, or the nut may be directly welded to the side of the front side rail 6 corresponding to the vehicle interior, and the entire nut may be the protruding portion 3311.

The first fastener 331 can be easily fixed to the side of the front cabin edge beam 6 corresponding to the vehicle interior by the above-described protruding portion 3311 using the first fastener 331. In comparison with the prior art in which the fastening member is provided on the side of the front side sill 6 corresponding to the outside of the vehicle or in a cavity in the front side sill 6, for example, in some prior art in which the nut plate is extended into the cavity of the front side sill 6, this results in difficulty in positioning the nut plate and difficulty in fitting the second fastening member 332 with the nut plate because the front side sill 6 has a certain length. In contrast, in the vehicle front cabin mechanism provided by the embodiment of the application, the protruding part 3311 can be utilized to fix the first fastening member 331 on the side of the front cabin edge beam 6 corresponding to the vehicle interior, so that the second fastening member 332 and the first fastening member 331 can be conveniently matched, and the mounting bracket 31, the lap joint piece 51 and the front cabin edge beam 6 can be conveniently fastened and connected together, so that the assembly time of the vehicle front cabin structure can be increased, the assembly efficiency can be improved, and the cost can be saved.

On this basis, referring to fig. 5, in some embodiments of the present application, the height of the protrusion 3311 and the depth of the relief recess 511 may also be adaptively adjusted such that the top of the protrusion 3311 abuts against the bottom of the relief recess 511.

Here, the top of the protruding portion 3311 means an end of the protruding portion 3311 away from the front cabin rail 1 in the vehicle width direction, and the bottom of the escape recess 511 means an end of the escape recess 511 away from the front cabin rail 1 in the vehicle width direction. Illustratively, referring to fig. 5, the top of the protrusion 3311 and the bottom of the relief recess 511 will be described with reference to the relative positions in fig. 5, wherein the top of the protrusion 3311 refers to the right end of the protrusion 3311 and the bottom of the relief recess 511 refers to the right end of the relief recess 511. With the above arrangement, the first fastener 331 can be pressed in the protruding direction of the protruding portion 3311 (e.g., the width direction of the vehicle) by the escape recess 511, so that the first fastener 331 can be restrained in the protruding direction of the protruding portion 3311 to the first fastener 331. Further, by applying an external force to the protruding portion 3311 in the protruding direction of the protruding portion 3311, the friction force between the protruding portion 3311 and the front cabin rail 1 and the lap joint 51 can be increased, and displacement of the first fastening member 331 in the protruding direction perpendicular to the protruding portion 3311 can be reduced or avoided also for the protruding portion 3311. This also corresponds to clamping the first fastener 331 between the bridge piece 51 and the front cabin rail 1, and can maintain the position of the first fastener 331 fixed, and can improve the mechanical properties of the first fastener 331. In particular, the shear performance of the first fastener 331 can be improved, so that the stability of the connection of the fastening member 33 can be improved. In addition, in some embodiments of the application, the size of the protrusion 3311 and the size of the relief recess 511 may also be adaptively adjusted such that the sidewall of the protrusion 3311 abuts against the sidewall of the relief recess 511.

The side wall of the protruding portion 3311 here means an outer edge structure of the protruding portion 3311 in a direction perpendicular to the vehicle width direction; the side wall of the avoidance concave 511 means the outer edge structure of the avoidance concave 511 in the direction perpendicular to the vehicle width direction.

Illustratively, referring to fig. 5, the side wall of the protruding portion 3311 and the side wall of the escape recess 511 will be described with reference to the relative positions in fig. 5, wherein the side wall of the protruding portion 3311 refers to the upper and lower ends of the protruding portion 3311, and the side wall of the escape recess 511 refers to the upper and lower ends of the escape recess 511.

In the embodiment of the present application, the side wall of the protruding portion 3311 may be brought into contact with the side wall portion of the relief recess 511, or the side wall of the protruding portion 3311 may be brought into contact with the side wall of the relief recess 511 entirely.

For example, referring to fig. 5, for providing the first fastener 331 as a blind rivet nut, the protruding portion 3311 may be provided in a cylindrical shape, and for this, the relief recess 511 may be provided in a cylindrical shape as well. On this basis, the diameter of the protruding portion 3311 and the diameter of the escape recess 511 may be set to match, so that only an installation gap is provided between the protruding portion 3311 and the escape recess 511 and no relative rattling may occur. Through the above arrangement, the first fastening member 331 can be limited by the bridge piece 51 along the protruding direction perpendicular to the protruding portion 3311, and the protruding portion 3311 can be supported by the recess 511 and the bridge piece 51, so that the first fastening member 331 can bear a larger external force, the shearing resistance of the first fastening member 331 can be further improved, and the connection stability of the fastening assembly 33 can be further improved.

On this basis, in some embodiments of the present application, the top of the protrusion 3311 may be abutted to the bottom of the escape recess 511 and the sidewall of the protrusion 3311 may be abutted to the sidewall of the escape recess 511 at the same time. By the arrangement, the first fastening member 331 can be completely limited between the bridge piece 51 and the front cabin longitudinal beam 1, the position of the first fastening member 331 can be further kept fixed, and the bridge piece 51 is used for supporting the first fastening member 331 in different directions, so that the mechanical property of the first fastening member 331 can be further improved, the shearing resistance of the first fastening member 331 can be further improved, and the connection stability of the fastening assembly 33 can be further improved.

In the embodiment of the present application, the specific arrangement of the reinforcing plate 313 is not limited, and the reinforcing plate 313 is connected between the top plate 311 and the side plate 312, and serves to reinforce the top plate 311 and the side plate 312. For example, one end of the reinforcement plate 313 may be fixedly coupled to the top plate 311, and the other end of the reinforcement plate 313 may be fixedly coupled to the side plate 312. In addition, the number of the reinforcing plates 313 may be set to one, or the number of the reinforcing plates 313 may be set to two or more, which is not limited in the embodiment of the present application.
