[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0029] It should be noted that in the automobile body skeleton structure, the side panel reinforcement plate assembly is a layer of internal reinforced sheet metal located between the side panel outer panel and the side panel inner panel. The existing side panel reinforcement plate assembly structure is mainly based on the side panel reinforcement plate body, and then supplemented by reinforcement plate components to improve the local strength of the vehicle body. However, the material thickness of the side panel reinforcement plate body has reached more than 1.8 mm. In order to ensure the strength of the reinforcement plate components, the reinforcement plate components of some models have a material thickness of more than 2.0 mm, which is costly and easily leads to an increase in the weight of the entire vehicle.
[0030] Based on this, the present application proposes a side reinforcement plate assembly 100, which utilizes an A-pillar reinforcement plate 12 to reinforce the strength of a side reinforcement plate body 11, and the A-pillar reinforcement plate 12 and the side reinforcement plate body 11 together form a first cavity 13, which is beneficial to improving the cross-sectional strength of the side reinforcement plate assembly 100 near the A-pillar, and while meeting the strength of the side reinforcement plate assembly 100, the material thickness of the A-pillar reinforcement plate 12 can be appropriately reduced, thereby helping to reduce costs and improve the lightweight design of the vehicle body.
[0031] The side reinforcement panel assembly 100 and the vehicle according to the embodiment of the present invention will be described below with reference to the accompanying drawings.
[0032] like Figure 1-Figure 5 As shown, according to the side panel reinforcement plate assembly 100 of the first aspect embodiment of the utility model, the side panel reinforcement plate assembly 100 is fixedly installed between the side panel outer panel 200 and the side panel inner panel 300, and the side panel reinforcement plate assembly 100 includes: a side panel reinforcement plate body 11 and an A-pillar reinforcement plate 12, the A-pillar reinforcement plate 12 is fixedly arranged on the side of the side panel reinforcement plate body 11 away from the side panel outer panel 200, and the A-pillar reinforcement plate 12 and the side panel reinforcement plate body 11 together form a first cavity 13.
[0033] Specifically, refer to Figure 3 and Figure 4As shown, the side wall reinforcement plate assembly 100 includes a side wall reinforcement plate body 11 and an A-pillar reinforcement plate 12, both of which are located between the side wall outer panel 200 and the side wall inner panel 300, wherein the A-pillar reinforcement plate 12 is fixedly installed on a side of the side wall reinforcement plate body 11 away from the side wall outer panel 200, and a portion of the A-pillar reinforcement plate 12 is spaced apart from the side wall reinforcement plate body 11 to form a first cavity 13, and further, the side wall reinforcement plate body 11 is also connected to the A-pillar upper inner panel of the side wall inner panel 300. 301 is fixedly connected, and the side reinforcement plate body 11 and the A-pillar upper inner plate 301 also enclose a cavity structure. It can be understood that the A-pillar reinforcement plate 12 acts as a partition plate of the cavity structure, thereby dividing the cavity structure into a first cavity 13 and a second cavity 14. In this way, the formation of two independent cavities is conducive to improving the cross-sectional strength of the side reinforcement plate assembly 100 near the A-pillar. At the same time, when the vehicle collides, the first cavity 13 and the second cavity 14 can absorb more collision energy to achieve better protection for the passengers. It should be noted that, by forming the first cavity 13 by the A-pillar reinforcement plate 12 and the side panel reinforcement plate body 11, while being able to meet the strength of the side panel reinforcement plate assembly 100, the material thickness of the A-pillar reinforcement plate 12 can be appropriately reduced. For example, the material thickness of the A-pillar reinforcement plate 12 can be less than 1.8 mm, and the A-pillar reinforcement plate 12 is separated from the side panel reinforcement plate body 11, so that the outer surface of the A-pillar reinforcement plate 12 is not completely in contact with the inner surface of the side panel reinforcement plate body 11, which is beneficial to reducing the size of the A-pillar reinforcement plate 12, and further reducing the material usage of the A-pillar reinforcement plate 12, which is beneficial to reducing costs and improving the lightweight design of the vehicle body.
[0034] According to the side reinforcement plate assembly 100 of the embodiment of the utility model, the side reinforcement plate assembly 100 utilizes the A-pillar reinforcement plate 12 to reinforce the strength of the side reinforcement plate body 11, and the A-pillar reinforcement plate 12 and the side reinforcement plate body 11 together form a first cavity 13, which is beneficial to improve the cross-sectional strength of the side reinforcement plate assembly 100 near the A-pillar, and while meeting the strength of the side reinforcement plate assembly 100, the material thickness of the A-pillar reinforcement plate 12 can be appropriately reduced, which is beneficial to reducing costs and improving the lightweight design of the vehicle body.
[0035] In some embodiments of the present invention, Figure 4 As shown, the cross section of the A-pillar reinforcement plate 12 is an "X"-shaped structure. Specifically, the A-pillar reinforcement plate 12 mainly bears the force from the height direction of the roof. The cross section of the A-pillar reinforcement plate 12 is an "X"-shaped structure, which can further improve the force bearing capacity of the A-pillar reinforcement plate 12, thereby further strengthening the strength of the side reinforcement plate body 11 near the A-pillar. When the vehicle collides, the deformation of the A-pillar reinforcement plate 12 can absorb more collision force, reduce the intrusion of the A-pillar into the interior of the vehicle body during the collision, and provide sufficient living space for passengers.
[0036] It should be noted that further reference Figure 4 As shown, the side reinforcement plate body 11 is a bent structure at the connection with the A-pillar reinforcement plate 12, which is equivalent to adding two welding surfaces. Therefore, it is convenient to adjust the normal angle of the welding gun during the welding process of the side reinforcement plate body 11 and the A-pillar reinforcement plate 12, ensuring that there is no interference between the welding gun and the A-pillar reinforcement plate 12 within 50mm of the normal direction, thereby meeting the welding feasibility. At the same time, by increasing the welding surface, the side reinforcement plate body 11 can be welded side by side with the A-pillar reinforcement plate 12 while meeting the gap requirements.
[0037] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the A-pillar reinforcement plate 12 has a through hole 121 communicating with the first cavity 13 .
[0038] It should be noted that the side enclosure reinforcement plate assembly 100 serves as a severely shielded box-mounted cavity structure. During electrophoresis, the electrophoretic liquid enters from the side enclosure inner plate 300. The side enclosure reinforcement plate assembly 100 needs to ensure sufficient gaps and openings to ensure that enough electrophoretic liquid flows into the cavity, thereby fully electrophoresing the entire side enclosure reinforcement plate assembly 100.
[0039] In some embodiments of the present invention, since the A-pillar reinforcement plate 12 separates the cavity structure enclosed by the side panel reinforcement plate body 11 and the A-pillar upper inner plate 301 into a first cavity 13 and a second cavity 14, it is necessary to ensure that the electrophoretic liquid flowing in from the A-pillar upper inner plate 301 flows smoothly into the first cavity 13 close to the outside of the vehicle. Based on this, the present application provides a through hole 121 in the A-pillar reinforcement plate 12 that is connected to the first cavity 13 formed by the A-pillar reinforcement plate 12 and the side panel reinforcement plate body 11. The electrophoretic liquid flowing in from the A-pillar upper inner plate 301 can pass through the through hole 121 and then into the first cavity 13, and then enter the cavity formed by the side outer panel 200 and the side panel reinforcement plate body 11 through the first cavity 13. In this way, by setting the through hole 121, sufficient flow space can be reserved for the electrophoretic liquid, thereby realizing electrophoretic treatment of the side panel reinforcement plate assembly 100.
[0040] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, there are multiple through holes 121, and the multiple through holes 121 are arranged at intervals along the length direction of the A-pillar reinforcement plate 12. That is to say, the A-pillar reinforcement plate 12 can be provided with multiple through holes 121 arranged at intervals along the length direction of the A-pillar reinforcement plate 12, and the number of through holes 121 can be 2, 3, 4, or 5, which is specifically provided according to actual needs and is not specifically limited here. In this way, by providing multiple through holes 121, the flow rate of the electrophoretic liquid flowing into the first cavity 13 can be further increased, and thus the side panel reinforcement plate assembly 100 can be better electrophoretically treated.
[0041] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the edge of the A-pillar reinforcement plate 12 has a through groove 122 connected to the first cavity 13. Specifically, in order to further improve the fluidity of the electrophoretic liquid in the side reinforcement plate assembly 100, a through groove 122 connected to the first cavity 13 is provided at the edge of the A-pillar reinforcement plate 12, so as to ensure that the electrophoretic liquid flowing into the first cavity 13 can flow out from the through groove 122 in time. It should be noted that the through groove 122 can be constructed as a boss structure, and the boss structure can be a boss with a height of 2 mm, which is conducive to further improving the self strength of the A-pillar reinforcement plate 12.
[0042] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, there are multiple through grooves 122, and the multiple through grooves 122 are arranged at intervals along the length direction of the A-pillar reinforcement plate 12. That is to say, the A-pillar reinforcement plate 12 can be provided with multiple through grooves 122 arranged at intervals along the length direction of the A-pillar reinforcement plate 12, and the number of through grooves 122 can be 2, 3, 4, or 5, which can be set according to actual needs and is not specifically limited here. For example, the A-pillar reinforcement plate 12 can be provided with a through groove 122 at intervals of 100 mm on the upper and lower welding surfaces. In this way, by providing multiple through grooves 122, the flow rate of the electrophoretic liquid out of the first cavity 13 can be further increased, and the side reinforcement plate assembly 100 can be better electrophoretically treated.
[0043] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, at least a portion of the A-pillar reinforcement plate 12 extends to the connection between the A-pillar upper section inner panel 301 and the A-pillar lower section inner panel 302 of the side wall inner panel 300 .
[0044] Specifically, the conventional A-pillar upper inner panel 301 and the A-pillar lower inner panel 302 are connected only by bolts. For example, the two are connected by only three bolts. When a vehicle collides, the connection between the A-pillar upper inner panel 301 and the A-pillar lower inner panel 302 is a weak area, and the bolt connection is prone to failure, which may cause the entire joint to bend or even break. Based on this, at least part of the A-pillar reinforcement plate 12 in the present application extends to the connection between the A-pillar upper section inner plate 301 and the A-pillar lower section inner plate 302 of the side wall inner plate 300. It can be understood that the A-pillar reinforcement plate 12 is arranged between the side wall outer plate 200 and the A-pillar upper section inner plate 301 and the A-pillar lower section inner plate 302, and part of the A-pillar reinforcement plate 12 extends to the connection between the A-pillar upper section inner plate 301 and the A-pillar lower section inner plate 302, or the A-pillar reinforcement plate 12 can continue to extend after extending to the connection between the A-pillar upper section inner plate 301 and the A-pillar lower section inner plate 302. For example, Figure 1 As shown, the A-pillar reinforcement plate 12 extends to below the connection between the A-pillar upper inner plate 301 and the A-pillar lower inner plate 302. This arrangement enhances the ability of the joint position to resist deformation in the width direction of the vehicle body during a collision. Even if the joint between the A-pillar upper inner plate 301 and the A-pillar lower inner plate 302 fails, the A-pillar reinforcement plate 12 can still play a supporting role to prevent the A-pillar from bending.
[0045] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the side reinforcement plate assembly 100 also includes: an upper side beam reinforcement plate 15, the upper side beam reinforcement plate 15 is fixedly connected to the side reinforcement plate body 11, and at least a portion of the A-pillar reinforcement plate 12 is overlapped at the connection between the upper side beam reinforcement plate 15 and the side reinforcement plate body 11. Specifically, the upper side beam reinforcement plate 15 is installed on the upper side beam of the vehicle, wherein one end of the upper side beam reinforcement plate 15 is fixedly connected to the side reinforcement plate body 11, and the A-pillar reinforcement plate 12 is at least partially overlapped at the connection between the upper side beam reinforcement plate 15 and the side reinforcement plate body 11, so that the joint position between the upper side beam reinforcement plate 15 and the side reinforcement plate body 11 can be reinforced to form a three-layer plate overlap structure, thereby achieving precise reinforcement at the joint, which is conducive to improving the force transmission path.
[0046] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the side reinforcement plate assembly 100 also includes: a B-pillar reinforcement plate assembly 16, and the two side edges of the A-pillar reinforcement plate 12 have a first flange 123 and a second flange 124, and the A-pillar reinforcement plate 12 is fixedly installed between the B-pillar reinforcement plate assembly 16 and the side reinforcement plate body 11 through the first flange 123 and the second flange 124.
[0047] Specifically, if Figure 2 As shown, the two side edges of the A-pillar reinforcement plate 12 have a first flange 123 and a second flange 124 that are relatively arranged, wherein the A-pillar reinforcement plate 12, the B-pillar reinforcement plate assembly 16, and the side reinforcement plate body 11 are all spot-welded by the first flange 123 and the second flange 124 to form a three-layer plate structure, so that the three parts are connected at the weak position to form a more complete load-bearing structure, which is conducive to further improving the strength of the vehicle body.
[0048] It should be noted that the B-pillar reinforcement plate assembly 16 can be designed with a flange structure at the door corner, which can fully exert the load-bearing function of the parts while ensuring stamping and further enhance the strength of the joint between the B-pillar reinforcement plate assembly 16 and the upper side beam.
[0049] The vehicle according to the second aspect of the present invention comprises the side reinforcement panel assembly 100 in the first aspect of the present invention.
[0050] According to the vehicle of the embodiment of the utility model, the side reinforcement plate assembly 100 is provided with the above-mentioned side reinforcement plate assembly 100, and the side reinforcement plate assembly 100 uses the A-pillar reinforcement plate 12 to reinforce the strength of the side reinforcement plate body 11, and the A-pillar reinforcement plate 12 and the side reinforcement plate body 11 together form a first cavity 13. In this way, it is beneficial to improve the cross-sectional strength of the side reinforcement plate assembly 100 near the A-pillar, and while meeting the strength of the side reinforcement plate assembly 100, the material thickness of the A-pillar reinforcement plate 12 can be appropriately reduced, which is beneficial to reducing costs and improving the lightweight design of the vehicle body.
