Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle body strengthening structures, and more specifically, relates to a side wall strengthening assembly and a vehicle. Background Art
[0002] An automobile body is sequentially provided with an A-pillar, a B-pillar and a C-pillar from front to back. The structures of the A-pillar and the B-pillar both include an inner panel, a reinforcing plate and an outer panel arranged from inside to outside. Among them, the A-pillar is connected to the front engine compartment, the front floor, the front enclosure, the sill beam, the roof, etc., and the B-pillar is connected to the roof, the sill beam, etc. The A-pillar and the B-pillar are important supporting and load-bearing members. The strength and stiffness of the A-pillar and the B-pillar are not only closely related to safety, but also highly correlated with NVH and BSR.
[0003] Due to the limited self-strength of the A-pillar and the B-pillar, a large amount of impact force cannot be effectively eliminated during a collision. Therefore, reinforcing plates are respectively arranged in the areas of the side wall reinforcing plate corresponding to the A-pillar and the B-pillar to increase the strength and stiffness of the A-pillar and the B-pillar. Since the reinforcing plates are arranged in a manner of being attached to the side wall reinforcing plate, the stiffness of the entire side wall assembly is weak. With the popularization of new energy vehicles, the vehicle body weight increases. If the strength of the A-pillar and the B-pillar areas is improved by increasing the thickness or the number of the reinforcing plates, the current requirements for the vehicle body weight cannot be met.
[0004] In addition, if the reinforcing plates are made of a material different from that of the side wall reinforcing plate and the yield strength of the reinforcing plates is increased by changing the material, the martensite transformation temperatures of the side wall reinforcing plate and the reinforcing plates will be inconsistent during the forming process, resulting in the precision of the formed side wall reinforcing plate not meeting the requirements. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a side wall strengthening assembly and a vehicle, aiming to solve the problems in the prior art that the side wall assembly has insufficient strength due to the reinforcing plates being arranged in a manner of being attached to the side wall reinforcing plate, but the vehicle body weight or the precision of the side wall reinforcing plate does not meet the standards after increasing the strength of the reinforcing plates.

[0035] Please refer to together Figures 1 to 3 , and now the side wall reinforcement assembly and the vehicle provided by the present utility model will be described. The side wall reinforcement assembly includes a side wall reinforcement plate 1, an A-pillar reinforcement member 3 and a B-pillar reinforcement member 2; the A-pillar reinforcement member 3 is connected to the side wall reinforcement plate 1 and forms a first cavity 103 with the side wall reinforcement plate 1 in the inner and outer directions; the B-pillar reinforcement member 2 is connected to the side wall reinforcement plate 1 and forms a second cavity 104 with the side wall reinforcement plate 1 in the inner and outer directions. The B-pillar reinforcement member 2 and the A-pillar reinforcement member 3 are spaced apart in the up and down direction and correspond to the rear part of the A-pillar reinforcement member 3.
[0036] The side wall reinforcement assembly provided by the present utility model, compared with the prior art, the A-pillar reinforcement member 3 and the B-pillar reinforcement member 2 of the side wall reinforcement assembly of the present utility model respectively form a first cavity 103 and a second cavity 104 with the side wall reinforcement plate 1 in the inner and outer directions. Not only the strength is increased and the moment of inertia is larger, but also it can better resist alternating stress and enhance the fatigue durability performance of the vehicle body. Due to the formation of the first cavity 103 and the second cavity 104, compared with the prior art solution in which the A-pillar reinforcement member 3 and the B-pillar reinforcement member 2 are both adhesively connected to the side wall reinforcement plate 1, when the vehicle has a side collision, part of the stress can be transmitted along the A-pillar reinforcement member 3 and the B-pillar reinforcement member 2, and the other part of the stress can be transmitted along the side wall reinforcement plate 1, increasing the force transmission path and improving the performance of the vehicle body in a frontal collision and a small overlap frontal collision, and it is easier to meet the increasingly stringent safety regulations. In addition, the cavity structures formed by the first cavity 103 and the second cavity 104 respectively make the collision force more evenly distributed on the cross-section, reduce the stress concentration phenomenon, and increase the torsional rigidity of the vehicle body.
[0037] It should be noted that the B-pillar reinforcement member 2 is provided corresponding to the B-pillar, and the A-pillar reinforcement member 3 is provided corresponding to the A-pillar.
[0038] Optionally, the dimensions of the first cavity 103 and the second cavity 104 in the inner and outer directions are greater than 5 mm, which avoids the problem of insufficient strength and stiffness caused by too small a distance between the A-pillar reinforcement member 3 and the B-pillar reinforcement member 2 and the side wall reinforcement plate 1, and at the same time avoids the interference between the A-pillar reinforcement member 3 or the B-pillar reinforcement member 2 and the side wall reinforcement plate 1 after being deformed by force.
[0039] Optionally, the B-pillar reinforcement member 2 is in a plate-like structure or a tubular structure.
[0040] It should be noted that the A-pillar reinforcement member 3 and the B-pillar reinforcement member 2 are spaced apart in the up and down directions, which avoids the problem of overweight of the entire side wall reinforcement assembly caused by too large a volume of the A-pillar reinforcement member 3 and the B-pillar reinforcement member 2, and can also save materials and reduce costs.
[0041] In some embodiments, please refer to Figure 1 and Figure 3 , the side wall reinforcement plate 1 includes a side wall main body 101 and a B-pillar reinforcement plate 102. The A-pillar reinforcement member 3 is connected to the side wall main body 101 and forms a first cavity 103 with the side wall main body 101 in the inner and outer directions; the B-pillar reinforcement plate 102 is connected to the side wall main body 101 and is located below the A-pillar reinforcement member 3, and the B-pillar reinforcement member 2 and the B-pillar reinforcement plate 102 form a second cavity 104 in the inner and outer directions.
[0042] In this embodiment, a B-pillar reinforcement plate 102 is added to increase the strength of the side wall reinforcement plate 1 corresponding to the B-pillar region and improve the safety performance of the B-pillar.
[0043] Optionally, the B-pillar reinforcement plate 102 is attached to the side wall main body 101.
[0044] It should be noted that whether to use the B main reinforcement plate to increase the strength of the B-pillar can be selected according to the actual situation of the vehicle. For example, for vehicles with a gross vehicle weight greater than 2500 KG, in order to meet the safety performance requirements and ensure that the roof crush is greater than four times the vehicle weight, the B-pillar reinforcement plate 102 is added. For vehicles with a gross vehicle weight less than 2500 KG, the design of the B-pillar reinforcement plate 102 can be cancelled.
[0045] Optionally, the B-pillar reinforcement plate 102 and the side wall reinforcement plate 11 have the same material and thickness, and the selected material thickness range is 1.0 - 2.5 mm.
[0046] Optionally, the B-pillar reinforcement member 2 is completely disposed on the B-pillar reinforcement plate 102, that is, the area of the B-pillar reinforcement plate 102 is larger than that of the B-pillar reinforcement member 2.
[0047] In some embodiments, please refer to Figure 1 and Figure 3 , the B-pillar reinforcement member 2 has a reinforcement area 203 protruding inward or outward.
[0048] The reinforcement area 203 protrudes inward or outward, which improves the strength and stiffness of the B-pillar reinforcement member 2 on the premise that the thickness and yield strength of the B-pillar reinforcement member 2 remain unchanged.
[0049] In some embodiments, please refer to Figure 1 and Figure 3 , the reinforcement area 203 is provided with a B-pillar weight reduction hole 2031.
[0050] The B-pillar weight reduction hole 2031 can reduce the weight of the B-pillar reinforcement member 2, which is beneficial to realizing the lightweight of the vehicle. In addition, since the protruding reinforcement area 203 is provided on the B-pillar reinforcement member 2 in this embodiment, there is no need to worry that opening the B-pillar weight reduction hole 2031 will cause insufficient strength of the B-pillar reinforcement member 2.
[0051] In some embodiments, please refer to Figure 1 , the A-pillar reinforcement member 3 includes a main reinforcement area 304 and an extension area 305 connected to the front end of the main reinforcement area 304, and the extension area 305 extends downward to the main reinforcement area 304.
[0052] The extension area 305 can strengthen the lower part of the A-pillar, avoiding the problem that the existing A-pillar reinforcement components only strengthen the upper part of the A-pillar and cannot take into account the lower part, resulting in a weak stress area in the lower part of the A-pillar. This embodiment enables the vehicle body to better transfer the force to the entire vehicle body skeleton under the frontal collision condition, preventing stress concentration and deformation in the lower section of the A-pillar, and better ensuring the safety of the occupants.
[0053] Optionally, the extension area 305 covers 10 - 20% of the area of the lower section of the A-pillar.
[0054] In some embodiments, see Figures 1 to 2 The A-pillar reinforcement 3 includes an A-pillar reinforcement body 301 and multiple A-pillar flanges 302. The A-pillar reinforcement body 301 and the side reinforcement plate 1 are spaced apart in the inner and outer directions; the multiple A-pillar flanges 302 are respectively connected to the opposite sides of the A-pillar reinforcement body 301 and bent toward the side away from the side reinforcement plate 1. The A-pillar flanges 302 are connected to the side reinforcement plate 1 and enclosed together with the A-pillar reinforcement body 301 and the side reinforcement plate 1 to form a first cavity 103.
[0055] The A-pillar reinforcement 301 and the A-pillar flange 302 are arranged at an angle, and are connected to the side reinforcement plate 1 through the A-pillar flange 302, thereby forming a first cavity 103. This structure not only increases the strength of the A-pillar reinforcement 3, but also has a simple structure, so that the opposite sides of the A-pillar reinforcement 301 are evenly stressed. The A-pillar flange 302 is bent toward the side away from the side reinforcement plate 1, which can not only better fit the flange of the side reinforcement plate 1, but also avoid the A-pillar reinforcement 3 and the side reinforcement plate 1 in the inner and outer directions. The distance is too large, which leads to the problem of occupying too much space in the vehicle.
[0056] Optionally, the A-pillar flange 302 has a plurality of reinforcement areas 3021 protruding toward a side away from the side reinforcement plate 1 , and the plurality of reinforcement areas 3021 are distributed at intervals along an extension path of the A-pillar reinforcement 3 .
[0057] In some embodiments, see Figure 3 The B-pillar reinforcement 2 includes a B-pillar reinforcement body 201 and multiple B-pillar flanges 202. The B-pillar reinforcement body 201 and the side reinforcement plate 1 are spaced apart in the inner and outer directions; the multiple B-pillar flanges 202 are respectively connected to the opposite sides of the B-pillar reinforcement body 201 and bent toward the side away from the side reinforcement plate 1. The B-pillar flanges 202 are connected to the side reinforcement plate 1 and enclosed together with the B-pillar reinforcement body 201 and the side reinforcement plate 1 to form a second cavity 104.
[0058] The B-pillar reinforcement 201 and the B-pillar flange 202 are arranged at an angle, and are connected to the side reinforcement plate 1 through the B-pillar flange 202, thereby forming a second cavity 104. This structure not only increases the strength of the B-pillar reinforcement 2, but also has a simple structure, so that the opposite sides of the B-pillar reinforcement 201 are evenly stressed. The B-pillar flange 202 is bent toward the side away from the side reinforcement plate 1, which can not only better fit the flange of the side reinforcement plate 1, but also avoid the problem of too large a distance between the B-pillar reinforcement 2 and the side reinforcement plate 1 in the inner and outer directions, thereby occupying too much space in the vehicle.
[0059] In some embodiments, see Figure 3 The B-pillar flange 202 has a plurality of reinforcement areas 2021 protruding toward the side away from the side reinforcement plate 1, and the plurality of reinforcement areas 2021 are spaced apart in the up-and-down direction.
[0060] The strengthening area 2021 increases the strength and stiffness of the B-pillar flange 202. Connection holes are provided on the B-pillar flange 202 for connecting the B-pillar flange 202 with other vehicle body components. The setting of the strengthening area 2021 can reduce the deformation probability of the B-pillar flange 202.
[0061] Optionally, the connection holes are provided in the strengthening area 2021.
[0062] In some embodiments, refer to Figure 1 , a plurality of A-pillar weight-reducing holes 303 are provided along the extending path of the A-pillar reinforcement 3, and two adjacent A-pillar weight-reducing holes 303 are spaced apart.
[0063] The A-pillar weight-reducing holes 303 can reduce the weight of the A-pillar reinforcement 3, which is beneficial to achieving vehicle lightweighting.
[0064] Based on the same inventive concept, the present utility model also provides a vehicle. The vehicle includes the above-mentioned side wall strengthening assembly.
[0065] For the vehicle provided by the present utility model, the above-mentioned side wall strengthening assembly is adopted. The A-pillar reinforcement 3 and the B-pillar reinforcement 2 respectively form a first cavity 103 and a second cavity 104 with the side wall strengthening plate 1 in the inner and outer directions. Not only the strength is increased and the moment of inertia is larger, but also it can better resist alternating stress and enhance the fatigue durability performance of the vehicle body. Due to the formation of the first cavity 103 and the second cavity 104, compared with the prior art in which both the A-pillar reinforcement 3 and the B-pillar reinforcement 2 are adhesively connected to the side wall strengthening plate 1, when the vehicle undergoes a side collision, part of the stress can be transmitted along the A-pillar reinforcement 3 and the B-pillar reinforcement 2, and the other part of the stress can be transmitted along the side wall strengthening plate 1, increasing the force transmission path and improving the vehicle body's frontal collision and small offset collision performance, and it is easier to meet the increasingly stringent safety regulations. In addition, the cavity structures formed by the first cavity 103 and the second cavity 104 respectively make the collision force more evenly distributed on the cross-section, reduce the stress concentration phenomenon, and increase the torsional rigidity of the vehicle body.
[0066] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
