[0038] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0039] Next, reference will be made to Figures 1 - 8 and in combination with the embodiments to detail the present utility model.

[0040] As Figures 1 through 8 shown, according to the A-pillar structure 100 of the embodiment of the present utility model, it includes an A-pillar body 10 and an internal reinforcement member 20. The A-pillar body 10 forms a cavity; the internal reinforcement member 20 is disposed in the cavity and is arranged in a plurality along the up and down direction. The plurality of internal reinforcement members 20 include a first reinforcement member 201 and a second reinforcement member 202. The first reinforcement member 201 and the second reinforcement member 202 are arranged in the inner and outer directions, and the first reinforcement member 201 and the second reinforcement member 202 arranged relatively in the inner and outer directions are partially staggered in the up and down direction.

[0041] Specifically, by arranging a plurality of internal reinforcement members 20 in the cavity of the A-pillar body 10, the plurality of internal reinforcement members 20 can strengthen the structural strength of the A-pillar body 10, so that the A-pillar body 10 is not easily deformed when being impacted, thereby reducing the deformation degree of the occupant compartment, especially the driver's cab, and reducing the risk or degree of injury to the occupants.

[0042] The plurality of internal reinforcement members 20 include a first reinforcement member 201 and a second reinforcement member 202, and the first reinforcement member 201 and the second reinforcement member 202 are arranged in the inner and outer directions. For example, the first reinforcement member 201 is disposed on the outer side, and the second reinforcement member 202 is disposed on the inner side; or, the first reinforcement member 201 is disposed on the inner side, and the second reinforcement member 202 is disposed on the outer side. The first reinforcement member 201 and the second reinforcement member 202 can respectively strengthen the inner side wall and the outer side wall of the A-pillar body 10, so that the overall structural strength of the A-pillar body 10 is improved preferably.

[0043] The first reinforcing member 201 and the second reinforcing member 202 arranged oppositely in the inner-outer direction are partially staggered in the up-down direction. Specifically, one first reinforcing member 201 may be provided, or multiple first reinforcing members 201 may be provided, and the multiple first reinforcing members 201 are arranged at intervals in the up-down direction; one second reinforcing member 202 may be provided, or multiple second reinforcing members 202 may be provided, and the multiple second reinforcing members 202 are arranged at intervals in the up-down direction. For the embodiment in which multiple first reinforcing members 201 are arranged at intervals, the space between a part of the second reinforcing member 202 and the adjacent first reinforcing member 201 is correspondingly arranged. For the embodiment in which multiple second reinforcing members 202 are arranged at intervals, the space between a part of the first reinforcing member 201 and the adjacent second reinforcing member 202 is correspondingly arranged.

[0044] In this way, the first reinforcing member 201 and the second reinforcing member 202 can cooperate with each other, so that the A-pillar can be well reinforced at various positions in the up-down direction, and at the same time, the number or volume of the first reinforcing member 201 and the second reinforcing member 202 is small, which is beneficial to preventing the overall weight of the A-pillar structure 100 from increasing too much.

[0045] According to the A-pillar structure 100 of the embodiment of the present utility model, by arranging a plurality of internal reinforcing members 20 in the A-pillar body 10, the internal reinforcing members 20 include a first reinforcing member 201 and a second reinforcing member 202, and the first reinforcing member 201 and the second reinforcing member 202 are arranged in the inner-outer direction to respectively reinforce the inner side wall and the outer side wall of the A-pillar body 10. At the same time, the first reinforcing member 201 and the second reinforcing member 202 arranged oppositely in the inner-outer direction are partially staggered in the up-down direction. In this way, on the one hand, the A-pillar body 10 can be reinforced at various positions in the up-down direction, and on the other hand, the overall mass of the A-pillar structure 100 will not increase too much; thereby, the structural strength of the A-pillar body 10 can be increased, the degree of deformation of the A-pillar body 10 when being impacted can be reduced, and thus the possibility or degree of injury to the occupants during the collision can be reduced.

[0046] According to some embodiments of the present utility model, reference may be made to Figure 1 and Figure 2 , the A-pillar body 10 includes an inner plate 101 and an outer plate 102 which are arranged oppositely and connected to each other in the inner-outer direction, and the inner plate 101 and the outer plate 102 jointly define a cavity; the first reinforcing member 201 is connected to the inner side wall of the outer plate 102, and the circumferential edge of the second reinforcing member 202 is clamped between the inner plate 101 and the outer plate 102.

[0047] The first reinforcing member 201 is connected to the inner side wall of the outer panel 102 to reinforce the outer panel 102. It should be noted that, compared with the inner panel 101, the outer panel 102 is usually impacted first. The first reinforcing member 201 is connected to the inner side wall of the outer panel 102, so that the reinforcing effect on the outer panel 102 is better, and the outer panel 102 is not easily deformed.

[0048] It should be noted that the inner panel 101 needs to be connected to some peripheral structures. For example, the inner panel 101 needs to be connected to a longitudinal beam. Therefore, if the second reinforcing member 202 is connected to the side wall of the inner panel 101, it will interfere with the connection of the longitudinal beam. Thus, the circumferential edge of the second reinforcing member 202 can be clamped between the inner panel 101 and the outer panel 102 to realize the installation and fixation of the second reinforcing member 202, and there will be no interference with other components installed on the inner panel 101.

[0049] According to some embodiments of the present invention, reference can be made to Figures 5 - 7 , the first reinforcing member 201 includes a first plate body 2011 and a first circumferential side plate 2012. The first circumferential side plate 2012 is disposed around the first plate body 2011. The second reinforcing member 202 is formed with a convex portion 2021, and the convex portion 2021 protrudes toward the inner panel 101.

[0050] The first circumferential side plate 2012 can be disposed around the first plate body 2011, or the first circumferential side plate 2012 can also be only connected to a part of the circumferential edge of the first plate body 2011.

[0051] The first reinforcing member 201 includes a first plate body 2011 and a first circumferential side plate 2012. The first circumferential side plate 2012 is disposed around the first plate body 2011. The first plate body 2011 is connected to the inner surface of the outer panel 102, and the first circumferential side plate 2012 is connected to the front side wall and the rear side wall of the outer panel 102. In this way, the structural strength of the first reinforcing member 201 is higher, and the reinforcing effect on the A-pillar body 10 is better.

[0052] The second reinforcing member 202 is formed with a convex portion 2021. In this way, the structural strength of the second reinforcing member 202 is higher, and the reinforcing effect on the A-pillar body 10 is better. The convex portion 2021 protrudes toward the inner panel 101. In this way, when the inner panel 101 is impacted and deformed, the second reinforcing member 202 can contact the inner panel 101 as soon as possible to absorb the impact energy.

[0053] According to some embodiments of the present invention, reference can be made to Figures 5 - 7, a plurality of internal reinforcing members 20 include a third reinforcing member 203, and the third reinforcing member 203 includes a first side plate 2031, a second side plate 2032 and a second circumferential side plate 2033. The first side plate 2031 and the second side plate 2032 are spaced apart in the inner and outer directions, and the second circumferential side plate 2033 is disposed around the first side plate 2031 or the second side plate 2032 and is connected between the first side plate 2031 and the second side plate 2032. The first side plate 2031 is connected to the inner plate 101, and the second side plate 2032 is connected to the outer plate 102.

[0054] That is to say, the third reinforcing member 203 can be connected between the inner plate 101 and the outer plate 102 and support between the inner plate 101 and the outer plate 102. In this way, the third reinforcing member 203 has a better strengthening effect on the A-pillar body 10, and the structural strength of the part of the A-pillar body 10 provided with the third reinforcing member 203 is higher, and it can better resist impact.

[0055] Specifically, the first side plate 2031 can be connected to the inner plate 101 through a threaded connecting member, and the second side plate 2032 and the outer plate 102 can be connected by welding. The first side plate 2031 can include a plurality of sub-side plates. Some of the sub-side plates can be opposite to the second side plate 2032 in the inner and outer directions, and some of the sub-side plates can be completely staggered from the second side plate 2032 in the inner and outer directions in projection.

[0056] According to some embodiments of the present invention, reference may be made to Figures 1 - 4 , the first reinforcing member 201 and the second reinforcing member 202 are disposed at the lower part of the A-pillar body 10. A longitudinal beam is connected to the inner side surface of the lower part of the A-pillar body 10, and the third reinforcing member 203 is disposed above the first reinforcing member 201 and the second reinforcing member 202.

[0057] Since a longitudinal beam is connected to the inner side surface of the lower part of the A-pillar body 10, the first reinforcing member 201 and the second reinforcing member 202 are disposed at the lower part of the A-pillar body 10. In this way, the installation of the first reinforcing member 201 and the second reinforcing member 202 will not interfere with the installation of the longitudinal beam, and the influence of the arrangement of the internal reinforcing members 20 on the original structure of the vehicle body is reduced. The third reinforcing member 203 is disposed above the first reinforcing member 201 and the second reinforcing member 202, and no longitudinal beam is connected to the part of the A-pillar body 10 corresponding to the upper part of the first reinforcing member 201 and the second reinforcing member 202. Therefore, the third reinforcing member 203 can be provided to obtain a better strengthening effect.

[0058] In some embodiments, reference may be made to Figure 3 , the third reinforcing member 203 is disposed in the middle of the A-pillar body 10, and a wheel well side beam 200 is connected to the middle of the A-pillar body 10. Thus, the third reinforcing member 203 can preferably absorb the collision force transmitted by the wheel well side beam 200 and reduce the deformation degree of the middle part of the A-pillar body 10.

[0059] According to some embodiments of the present invention, reference can be made to Figure 8 The A-pillar structure 100 further includes an external reinforcement 30, which is disposed at the lower front side of the A-pillar body 10. The external reinforcement 30 is used to connect the inner panel 101 and the outer panel 102, so that when the inner panel 101 and the outer panel 102 are impacted, the possibility of cracking of the weld between the inner panel 101 and the outer panel 102 can be reduced. Specifically, the external reinforcement 30 can be directly connected between the inner panel 101 and the outer panel 102, or the external reinforcement 30 can also be connected between the outer panel 102 and the longitudinal beam, and the longitudinal beam is connected to the inner panel 101, so as to realize the connection between the inner panel 101 and the outer panel 102. In this way, the connection area of the external reinforcement 30 is large and the connection strength is high.

[0060] Another object of the present invention is to provide a vehicle body structure 1000 , comprising the A-pillar structure 100 according to the embodiment of the present invention.

[0061] Compared with the prior art, the advantages of the vehicle body structure 1000 of the present invention are the same as those of the A-pillar structure 100 of the embodiment of the present invention, which will not be described in detail here.

[0062] During a 64SORB collision, the wheel arch side beam 200 will be crushed and transfer energy backwards, transferring the collision energy to the A-pillar body 10, or the wheel and the barrier will contact and transfer the collision energy to the A-pillar body 10, or the A-pillar body 10 will be directly hit.

[0063] According to some embodiments of the present invention, the vehicle body structure 1000 also includes a wheel arch side beam 200, the rear end of which is connected to the front side of the middle part of the A-pillar body 10, and the size of the rear end of the wheel arch side beam 200 in the up-down direction is greater than the size of the front end of the wheel arch side beam 200 in the up-down direction. In other words, the connection area between the wheel arch side beam 200 and the A-pillar body 10 is large, so as to transfer the force to various parts of the A-pillar structure 100 in a dispersed manner as much as possible, thereby reducing the possibility of excessive concentration of force on the A-pillar structure 100, which is beneficial to reducing the possibility of large local deformation of the A-pillar structure 100.

[0064] According to some embodiments of the present invention, Figure 1 , Figure 2 and Figure 8As shown, the vehicle body structure 1000 further includes a sill beam 300. The lower end of the A-pillar body 10 is connected to the front end of the sill beam 300. Thus, when the A-pillar structure 100 is subjected to an impact force, the impact force will be transmitted to the sill beam 300. The sill beam 300 is formed with a concave cavity, and a reinforcing beam 400 is disposed through the concave cavity. The reinforcing beam 400 is connected to the sill beam 300. By providing the reinforcing beam 400 to reinforce the sill beam 300, the possibility of deformation of the sill beam 300 can be reduced, and further, the possibility of deformation of the passenger compartment, especially the driver's compartment, can be reduced, and the risk or degree of injury to the occupants can be reduced.

[0065] More specifically, the reinforcing beam 400 can be an extruded aluminum reinforcing beam, which has high strength and light weight and will not excessively increase the mass of the vehicle. A plurality of reinforcing ribs are formed inside the reinforcing beam 400 and are distributed in a staggered manner, so that the reinforcing beam 400 has higher structural strength. The lower part and the side part of the reinforcing beam 400 can be connected to the inner side wall of the sill beam 300, for example, by bolts, so that the connection effect between the reinforcing beam 400 and the sill beam 300 is better.

[0066] Another object of the present invention is to provide a vehicle, including the vehicle body structure 1000 according to the embodiment of the present invention.

[0067] Compared with the prior art, the advantages of the vehicle of the present invention are the same as those of the vehicle body structure 1000 according to the embodiment of the present invention, and will not be elaborated here.
