[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0035] The embodiment of the present application provides a vehicle body side panel assembly, and the structural schematic diagram of the vehicle body side panel assembly is as follows: Figure 1 As shown. The vehicle body side assembly includes a front pillar structure 100 and a beam structure 300 disposed on the top of the front pillar structure 100. The front pillar structure 100 includes a first reinforcing plate 101 and a second reinforcing plate 102 connected to each other, and the first reinforcing plate 101 is connected to the beam structure 300. The material of the first reinforcing plate 101 includes a first alloy, and the material of the second reinforcing plate 102 includes a second alloy. The strength of the first alloy is greater than the strength of the second alloy, and the weight of the second alloy is lighter than the weight of the first alloy.
[0036] In this embodiment, the first reinforcing plate 101 is connected to the beam structure 300, and the second reinforcing plate 102 is located below the first reinforcing plate. Then the first reinforcing plate 101 serves as a connecting column connecting the roof at the left front and right front of the vehicle, and the second reinforcing plate 102 serves as a connecting column connecting the front cabin at the left front and right front of the vehicle. The first reinforcing plate 101 is made of a metal material with greater strength and heavier weight, which can effectively resist greater external forces on the vehicle, thereby protecting the heads of passengers, etc. The second reinforcing plate 102 is made of a metal material with lighter weight and lower strength, which can not only play a role in resisting certain external forces, but also reduce the weight of the vehicle. Therefore, the present application uses suitable materials in suitable positions, which is beneficial to improving the collision safety of the vehicle, but also helps to reduce the weight of the vehicle and achieve lightweighting of the vehicle, thereby effectively extending the vehicle's cruising range.
[0037] Alternatively, if Figure 1 and Figure 3 As shown, the first alloy includes at least one of a steel alloy and an iron alloy; the second alloy includes at least one of an aluminum alloy, a magnesium alloy and a titanium alloy.
[0038] Exemplarily, the first alloy is a steel alloy, and the second alloy is an aluminum alloy. The first alloy is made of a steel alloy profile, so that the vehicle portion has high strength, high rigidity, and high collision performance. The second alloy is made of an aluminum alloy profile, so that the vehicle reduces the weight of the vehicle body while taking into account rigidity and strength.
[0039] Alternatively, if Figure 2 and Figure 3 as well as Figure 6 As shown, the first reinforcing plate 101 and the second reinforcing plate 102 are connected by a first method, and the first method includes hot-melt self-tapping screws.
[0040] In this embodiment, since the first reinforcing plate 101 and the second reinforcing plate 102 are connected by hot-melt self-tapping, the first reinforcing plate 101 and the second reinforcing plate 102 can be connected on one side, reducing the demand for space on both sides of the first reinforcing plate 101 and the second reinforcing plate 102. In this way, the installation requirements of the first reinforcing plate 101 and the second reinforcing plate 102 made of cavity profiles are met.
[0041] Alternatively, if Figure 2 and 3 As shown in the figure, the vehicle body side assembly further includes a center pillar structure 200 , and the material of the center pillar structure 200 includes a first alloy.
[0042] The vehicle body side assembly further includes a beam structure 300. The beam structure 300 includes a first portion 301, a second portion 302, and a third portion 303 connected in sequence. Figure 2 As shown by the short dashed line, the material of the beam structure 300 includes a second alloy.
[0043] The front pillar structure 100 is connected to the first part 301 by a first method, and the middle pillar structure 200 is connected to the second part 302 by a first method.
[0044] In this embodiment, the center pillar structure 200 is between the front seat and the rear seat of the cockpit. The center pillar structure 200 uses the first alloy as the material constituting the center pillar structure 200 to ensure the safety of the passengers in the cockpit.
[0045] The center pillar structure 200 is connected to the beam structure 300 to improve the structural strength of each portion of the beam structure 300 for supporting the roof.
[0046] The front pillar structure 100 and the first part 301 are connected by hot-melt self-tapping screws, so that a metal connection is formed between the front pillar structure 100 and the beam structure 300, reducing the damage to the material caused by perforation in traditional screw connections, and making the connection strength between the front pillar structure 100 and the beam structure 300 high.
[0047] Alternatively, if Figure 1 and 2 As shown in the figure, the body side assembly further includes a rear pillar structure 400 , and the material of the rear pillar structure 400 includes a second alloy.
[0048] The rear pillar structure 400 is connected to the third portion 303 of the beam structure 300 by a second method, and the second method includes metal-arc argon arc welding.
[0049] In this embodiment, the rear pillar structure 400 made of aluminum alloy has good rigidity and light weight, so that the rear pillar structure 400 meets the lightweight requirements of the entire vehicle.
[0050] The rear pillar structure 400 and the beam structure 300 are connected by argon arc welding, so that the connection efficiency between the rear pillar structure 400 and the beam structure 300 is high, which can effectively reduce the production cost, and make the weld between the rear pillar structure 400 and the beam structure 300 well formed, which can ensure the integrity and reliability of the metal material after welding and improve the safety of the rear passengers.
[0051] like Figure 2 and Figure 3 As shown, the vehicle body side assembly further includes a door pillar structure 500, which includes a first section 501, a second section 502 and a third section 503 connected to each other. The first section 501, the second section 502 and the third section 503 are as shown in FIG. Figure 2 As shown by the short dashed lines; the first section 501 is connected to the second reinforcing plate 102, the second section 502 is connected to the bottom of the middle pillar structure 200, and the third section 503 is connected to the bottom of the rear pillar structure 400; the first section 501, the front pillar and the first part 301 of the beam structure 300 form a front door opening, and the second section 502, the second part 302 of the beam structure 300 and the rear pillar structure 400 form a rear door opening.
[0052] Understandably, Figure 2 The short dashed lines between the first section 501, the second section 502 and the third section 503 are provided for ease of understanding. The first section 501, the second section 502 and the third section 503 can be formed independently or integrally.
[0053] Optionally, the material of the door pillar structure 500 includes the second alloy. The first section 501 and the second reinforcing plate 102, the third section 503 and the rear pillar structure 400 are connected in the second manner. The second section 502 and the middle pillar structure 200 are connected in the first manner.
[0054] In this embodiment, the door pillar structure 500 is made of aluminum alloy profiles, so that the weight of the vehicle body can be reduced while taking into account both rigidity and strength.
[0055] In this embodiment, Figure 1 and Figure 5 As shown, the door post structure 500 includes a plurality of cavities.
[0056] In this embodiment, the door pillar structure 500 forms a cavity, so that the door pillar structure 500 ensures structural strength and has a good side impact energy absorption effect, thereby improving the safety performance of the vehicle.
[0057] like Figure 1 and Figure 2 As shown, the body side assembly further includes an outer panel structure, and the outer panel structure 600 is disposed on a side of the rear pillar structure 400 and the beam structure 300 close to the exterior of the vehicle.
[0058] In this embodiment, the rear pillar structure 400 and the beam structure 300 are protected by the outer panel structure 600 on the outer side of the rear pillar structure 400 and the beam structure 300, thereby improving the safety performance of the rear row of the vehicle.
[0059] In addition, the present invention also provides a vehicle, including a vehicle body side panel assembly, wherein the vehicle body side panel assembly is the vehicle body side panel assembly described in any of the above embodiments.
[0060] Since the body side panel assembly has the above-mentioned technical effects, a vehicle including the body side panel assembly should also have corresponding technical effects, which will not be elaborated here.
[0061] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
