For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in combination with specific situations

[0048] The present invention will be described in detail below with reference to the drawings and in combination with embodiments

[0049] This embodiment relates to a front body structure. As a whole, the front body structure includes a front panel assembly that is connected to the vehicle body A-pillar 2 and encloses to form a foot activity space 400. The front panel assembly includes a front panel 1, and a lower front panel 103 and a front connecting plate 104 are provided on both the left and right sides of the front panel 1

[0050] Among them, the upper part of the front bulkhead 1 is connected between the two side body A-pillars 2, the front bulkhead lower panel 103 is connected to the lower part of the front bulkhead 1 and the corresponding side body A-pillar 2, and at least part of the front bulkhead connecting plate 104 is connected within the area enclosed by the front bulkhead 1, the front bulkhead lower panel 103 and the body A-pillar 2, and a protruding part 1041 is provided on the front bulkhead connecting plate 104, and the protruding part 1041 protrudes outwards towards the foot activity space 400.

[0051] For the front body structure of this embodiment, by connecting at least part of the front bulkhead connecting plate 104 within the area enclosed by the front bulkhead 1, the front bulkhead lower panel 103 and the body A-pillar 2, and providing a protruding part 1041 protruding outwards towards the foot activity space 400 on the front bulkhead connecting plate 104, it is beneficial to increase the foot activity space 400, thereby improving the freedom and comfort of foot movement, and further beneficial to improving the riding comfort of the vehicle.

[0052] Based on the above overall introduction, an exemplary structure of the front body structure described in this embodiment is as Figures 1 to 4 shown in. Preferably, the front bulkhead 1 in this embodiment includes a connected front bulkhead upper panel 101 and a front bulkhead middle panel 102. Both sides of the front bulkhead upper panel 101 are respectively connected to the corresponding side body A-pillar 2, and the front bulkhead middle panel 102 is spaced from the corresponding side body A-pillar 2.

[0053] At the bottom of the middle part of the front bulkhead, a rear connecting plate 108 of the front bulkhead extending rearward is provided. The cross-section of the rear connecting plate 108 of the front bulkhead is in an "n" shape, and it is used to connect to the middle channel. The above-mentioned front bulkhead lower panel 103 is respectively arranged on the left and right sides of the rear connecting plate 108 of the front bulkhead. For the convenience of description, the area enclosed by the front bulkhead 1, the front bulkhead lower panel 103 and the body A-pillar 2 is defined as the installation area 500.

[0054] As Figure 5 shown in, the installation area 500 is in a quasi-triangular shape. A quasi-triangle means that at least one of the three sides is non-linear, but it is triangular in overall composition. Here, by setting the installation area 500 in a quasi-triangular shape, the characteristic that a triangle has stability can be utilized, which is beneficial to improving the structural strength at the installation area 500.

[0055] Specifically, the body A-pillar 2 located between the front bulkhead upper panel 101 and the front bulkhead lower panel 103 constitutes the first side of the quasi-triangle. The top of the first side is connected to the end of the front bulkhead middle panel 102 to form the second side of the quasi-triangle, and the bottom of the first side is connected to the end of the front bulkhead middle panel 102 to form the third side of the quasi-triangle.

[0056] Preferably, as Figure 6As shown, along the direction away from the vehicle body A-pillar 2, the width of the part of the front bulkhead connecting plate 104 located within the area gradually decreases. That is to say, the shape of the front bulkhead connecting plate 104 located within the installation area 500 is adapted to the shape of the installation area 500, which is beneficial to further enhancing the structural strength of the front bulkhead connecting plate 104 itself. At the same time, it is also beneficial to guide the front-end collision force to be dispersed and transmitted backward.

[0057] In this embodiment, the four sides of the front bulkhead connecting plate 104 are respectively welded and connected to the end of the front bulkhead middle plate 102, the vehicle body A-pillar 2, the lower edge of the end of the front bulkhead upper plate 101, and the outer edge of the front bulkhead lower plate 103. The vehicle body A-pillar 2 in this embodiment includes an A-pillar inner panel 201 and an A-pillar outer panel 202 that are snap-connected. Among them, the front bulkhead connecting plate 104 is specifically lap-connected to the A-pillar inner panel 201.

[0058] In this embodiment, the front bulkhead connecting plate 104 not only seals the installation area 500, but also helps to form the foot activity space 400, and is also beneficial to improving the structural strength of the foot activity space 400. At the same time, by providing the front bulkhead connecting plate 104, it is also beneficial to enhancing the connection strength between the front bulkhead 1 and the vehicle body A-pillar 2, which plays a key role in improving the force transmission and torsion of the whole vehicle.

[0059] As Figure 6 shown, in this embodiment, the distance between the front bulkhead connecting plate 104 and the rear front bulkhead connecting plate 108 in the vehicle width direction gradually increases along the direction pointing to the vehicle tail. In this way, the front bulkhead connecting plate 104 increases the foot activity space 400 in the vehicle length direction and width direction, which is beneficial to the formation of the foot activity space 400.

[0060] As a preferred implementation manner, still as Figure 6 shown, the protruding part 1041 on the front bulkhead connecting plate 104 is located in the middle of the front bulkhead connecting plate 104 and extends along the left-right direction of the vehicle. Such a setting is not only beneficial to increasing the occupancy of the foot activity space 400 in the vehicle width direction, but also beneficial to increasing the occupancy of the foot activity space 400 in the vehicle height direction, thereby enhancing the freedom and comfort of foot movement. In addition, the structure of the protruding part 1041 is simple and easy to process and form.

[0061] Combined with Figures 6 to 8 shown, a front bulkhead connecting outer plate 105 is connected to the side of the front bulkhead connecting plate 104 facing outside the foot activity space 400, and a first cavity 100 is formed by enclosing the front bulkhead connecting outer plate 105 and the front bulkhead connecting plate 104. As a preference, an inner reinforcing plate 1043 located within the first cavity 100 is provided on the front bulkhead connecting plate 104 to further improve the structural strength of the front bulkhead connecting plate 104.

[0062] In addition, the shape and size of the front enclosure connecting outer panel 105 are adapted to those of the front enclosure connecting plate 104, which is beneficial to improving the use effect of the first cavity 100, thereby utilizing the effect of the first cavity 100 in enhancing stiffness and achieving the purpose of improving the connection effect between the front panel 1 and the vehicle body A-pillar 2.

[0063] As a preferred embodiment, as Figure 7 shown in Figure 8 , an indentation 1051 is provided on the front enclosure connecting outer panel 105. The indentation 1051 is provided corresponding to the protruding portion 1041 and indents into the foot activity space 400. As

[0064] shown in

[0065] , due to the arrangement of the protruding portion 1041 and the indentation 1051, the middle part of the first cavity 100 is necked down, and the cross-section of the entire first cavity 100 is elongated in the vehicle height direction, that is, the first cavity 100 is a special-shaped necked-down structure. Figure 2 and Figures 9 to 11 shown in

[0066] , the front enclosure lower panel 103 is connected to the front enclosure middle panel 102, and an outwardly protruding portion 1021 protruding toward the vehicle head side is provided on the front enclosure middle panel 102, and the outwardly protruding portion 1021 extends along the length direction of the front enclosure middle panel 102. Among them, the widths of both ends of the front enclosure middle panel 102 are gradually increased along the direction away from the middle, so that the front enclosure middle panel 102 is large at both ends and small in the middle, presenting a "dumbbell shape". Among them, the widths of both ends of the front enclosure middle panel 102 are relatively large, which is beneficial to enclosing and forming the foot activity space 400 and is beneficial to improving the connection between the front enclosure middle panel 102 and surrounding components. Figure 10 shown in Figure 11 shown in

[0067] In this embodiment, the protruding length of the front bulkhead middle plate 102 at the end is relatively large, which is conducive to increasing the space occupied by the foot activity space 400 in the vehicle length direction, further improving the freedom of foot movement, and the structure of the convex part 1021 is simple, which is convenient for processing and forming on the front bulkhead middle plate 102.

[0068] Refer to Figure 2 and Figure 15 As shown in, a front bulkhead outer reinforcement plate 106 is connected to the side of the front bulkhead middle plate 102 facing outside the foot activity space 400, and a second cavity 200 is formed by enclosing the front bulkhead outer reinforcement plate 106 and the front bulkhead middle plate 102, and the second cavity 200 extends along the left - right direction of the vehicle. By arranging the front bulkhead outer reinforcement plate 106 and the second cavity 200 on the front bulkhead middle plate 102, it is conducive to improving the structural strength of the front bulkhead middle plate 102, and using the high - load - bearing structural characteristics of the second cavity 200, it is conducive to enhancing the ability of the front bulkhead 1 to resist collision impacts.

[0069] In terms of the specific structure, as Figure 12 and Figure 13 shown in, the front bulkhead connecting plate 104 has an extension part 1042 extending forward to the front side of the front bulkhead middle plate 102, and the left and right sides of the front bulkhead outer reinforcement plate 106 are connected to the extension parts 1042 of the corresponding side front bulkhead connecting plates 104. Such an arrangement is conducive to strengthening the connection strength between the front bulkhead outer reinforcement plate 106, the front bulkhead connecting plate 104 and the front bulkhead 1, and is conducive to the connection of the first cavity 100 and the second cavity 200, thereby enhancing the absorption and dispersion transfer effects of the two on the collision force.

[0070] The front bulkhead outer reinforcement plate 106 in this embodiment includes an outer upper reinforcement plate 1061 and an outer lower reinforcement plate 1062 connected up and down. Among them, the outer upper reinforcement plate 1061 is inclined forward in the vehicle height direction. Specifically, the two ends of the outer upper reinforcement plate 1061 are respectively connected to the front bulkhead connecting plates 104 arranged at the same end, the top of the outer upper reinforcement plate 1061 is connected to the bottom of the front bulkhead upper plate 101, and the bottom of the outer upper reinforcement plate 1061 is connected to the outer lower reinforcement plate 1062. The outer lower reinforcement plate 1062 covers the outside of the entire front bulkhead lower plate 103.

[0071] Here, the cooperation scheme of the outer upper reinforcement plate 1061 and the outer lower reinforcement plate 1062 in the front bulkhead outer reinforcement plate 106 is conducive to processing and forming, and is convenient for arranging and implementing on the front bulkhead 1. In addition, by covering the outer lower reinforcement plate 1062 on the side of the entire front bulkhead lower plate 103 facing the outside of the vehicle, the structural strengthening effect on the front bulkhead lower plate 103 is improved, and it is conducive to increasing the space occupied by the second cavity 200, further enhancing the resistance effect of the front bulkhead 1 to the collision impact force.

[0072] To further improve the usage effect of the front body structure, a lower front reinforcement panel 107 is provided at the bottom of each lower front panel 103. The lower front reinforcement panel 107 is connected to the lower front panel 103, the middle front panel 102, and the front connecting panel 104, and a third cavity 300 is formed by enclosing. As Figure 13 and Figure 14 shown in the figure, each lower front reinforcement panel 107 is arranged at the front end of the lower front panel 103 and extends in the direction of the vehicle head.

[0073] Among them, the bottom of the lower front reinforcement panel 107 is convex downward to facilitate the formation of the third cavity 300. The front end of the lower front reinforcement panel 107 is connected to the bottom of the middle front panel 102, and the outer side of the lower front reinforcement panel 107 is connected to the extending part 1042.

[0074] In this embodiment, the setting of the lower front reinforcement panel 107 and the third cavity 300 is beneficial to improving the structural strength of the lower front panel 103, and by using the characteristic that the third cavity 300 can absorb vibration, it is beneficial to reduce the transmission of external excitation sources such as horns and windshield wiper motors to the foot activity space 400, thereby improving the comfort of the foot activity space 400.

[0075] For the front body structure of this embodiment, by providing a protruding part 1041 on the front connecting panel 104 and an outward protruding part 1021 protruding toward the vehicle head on the middle front panel 102, it is beneficial to increase the space occupancy of the foot activity space 400 in the front-back direction and the left-right direction of the whole vehicle, thereby facilitating the enlargement of the foot activity space 400 and improving the riding comfort.

[0076] In addition, by providing the first cavity 100 and the third cavity 300, using the high-strength load-bearing advantage of the cavity, it is beneficial to improve the safety collision performance of the front panel area, effectively reduce the intrusion amount of the front panel assembly during a frontal collision, and reduce the damage to the feet of the occupants during the collision. Also, by providing the first cavity 100, the second cavity 200, and the third cavity 300, it is not only beneficial to improve the effect of the front panel assembly in dispersing and transmitting the collision force, but also beneficial to absorbing the external excitation energy such as horns and windshield wiper motors, thereby reducing the foot vibration sensation and improving the riding comfort.

[0077] In addition, this embodiment relates to a vehicle, which includes the front body structure as described above. In this embodiment, by providing the front body structure as described above in the vehicle body, it is beneficial to improve the riding comfort and safety of the vehicle.

[0078] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
