[0034] See also Figure 1 and Figure 2 The vehicle body 100 of the embodiment of the present application includes an A-pillar 10, a sill beam 20 and a force transmission component 30. The A-pillar 10 includes a lower end portion 12 close to the ground; the sill beam 20 is connected to the lower end portion 12; the force transmission component 30 is installed on the lower end portion 12, and the force transmission component 30 includes a first tube 31 and a second tube 32. The first tube 31 and the second tube 32 clamp a part of the lower end portion 12, and along the direction toward the front of the vehicle, the first tube 31 and the second tube 32 both protrude from the lower end portion 12.
[0035] See also Figure 1 The present application provides a vehicle 200 , which includes a chassis 110 and a body 100 , wherein the body 100 is disposed on the chassis 110 .
[0036] In the vehicle body 100 of the embodiment of the present application, the force transmission component 30 is installed on the lower end portion 12, wherein the first tube 31 and the second tube 32 of the force transmission component 30 are hollow structures, which are easy to deform and have a good energy absorption effect. In addition, the first tube 31 and the second tube 32 both protrude from the lower end portion 12, so that the force bearing area is increased and the energy absorption effect is better, thereby being able to absorb the energy generated by the collision to a greater extent and enhancing the energy absorption effect.
[0037] Specifically, the vehicle 200 can be a new energy powered vehicle or a fuel powered vehicle. The vehicle body 100 can refer to the portion of the vehicle 200 used to carry people and load cargo. The A-pillar 10 is a pillar in the vehicle body 100. The A-pillar 10 can be a connecting pillar connecting the roof and the front cabin at the left front and right front. The material of the A-pillar 10 can be a stamped steel plate material or a hot-formed steel material. The sill beam 20 is a beam located directly below the vehicle door. The material of the sill beam 20 can be an iron-aluminum alloy. The force transmission component 30 refers to a component that can transmit force after receiving force.
[0038] The force transmission component 30 may include a first tube 31 and a second tube 32. The first tube 31 and the second tube 32 may be aluminum tube beams, which may be produced by an aluminum extrusion process, wherein the aluminum extrusion process may be to form the original aluminum into an extruded profile or a channel, and the round stock aluminum is slowly extruded through a die by a hydraulic plunger. The die may be a hollow profile that can form the aluminum into a predetermined precise extrusion shape. The thickness of the aluminum tube beam is 3 mm, which greatly improves the strength of the structure. The density of the aluminum profile is about 1 / 3 of that of the steel. By using the aluminum profile and the aluminum extrusion process, the force transmission and energy absorption performance of the structure are improved while having the advantage of being lightweight.
[0039] The first tube 31 and the second tube 32 sandwich a portion of the lower end 12, and in the direction toward the front of the vehicle, the first tube 31 and the second tube 32 both protrude from the lower end 12, thereby increasing the force bearing area during a collision, and enhancing the energy absorption effect of the first tube 31 and the second tube 32. Compared with a single aluminum extruded tube beam as a force transmission structure, the combination of a high-strength steel plate and two aluminum tube beam structures has a larger force bearing area, a more stable structure, a higher strength, and better force transmission and energy absorption performance.
[0040] The force transmission component 30 is installed on the lower end portion 12 as a force transmission and energy absorption structure for small offset collisions. During a small offset collision, it effectively improves the stability of force transmission in the "front wheel-door sill" path, reduces the intrusion deformation of the A-pillar 10, and effectively ensures the safety of the occupants in the vehicle.
[0041] See also Figure 2 In some embodiments, the first tube 31 and / or the second tube 32 is provided with a first reinforcing rib 311, and the first reinforcing rib 311 is connected to the inner wall of the tube. In other words, in some embodiments, the first tube 31 is provided with the first reinforcing rib 311, the second tube 32 is provided with the first reinforcing rib 311, or both the first tube 31 and the second tube 32 are provided with the first reinforcing rib 311.
[0042] In this way, by providing the first reinforcing ribs 311 on the first tube 31 and the second tube 32 , the structural strength and energy absorption characteristics of the first tube 31 and the second tube 32 can be greatly improved.
[0043] Specifically, during the structural design process, the overhanging surface of the structure may be too large or the span may be too large. In this case, the load that the connection surface of the structural member itself can bear is limited, so reinforcing ribs are added to the common vertical surface of the two combined bodies to increase the strength of the connection surface. The first reinforcing rib 311 connects the inner wall of the tube to improve the structural strength of the first tube 31 and the second tube 32, and enhances the energy absorption effect of the first tube 31 and the second tube 32.
[0044] See also Figure 2In some embodiments, the number of the first reinforcing ribs 311 is multiple, and the multiple first reinforcing ribs 311 are arranged crosswise. In this way, by providing multiple first reinforcing ribs 311 and making the first reinforcing ribs 311 arranged crosswise, the structural strength of the first tube 31 and the second tube 32 can be enhanced and the structural stability can be improved.
[0045] Specifically, a plurality of first reinforcing ribs 311 can improve the structural strength, wherein the cross-arrangement of the plurality of first reinforcing ribs 311 can improve the stability of the structure, so that the first tube 31 and the second tube 32 are not easily damaged when subjected to force.
[0046] See also Figure 1-5 In some embodiments, the force transmission component 30 includes a mounting plate 33, the mounting plate 33 includes a force plate 331 facing the front of the vehicle, the force plate 331 is fixedly connected to the first tube 31 and the second tube 32, and the force plate 331 is installed at the lower end 12. In this way, the installation plate 33 can improve the structural strength, and by fixing the force plate 331 to the first tube 31 and the second tube 32 and installing the force plate 331 at the lower end 12, the contact area can be increased, so that the force transmission is more stable.
[0047] Specifically, the material of the mounting plate 33 can be steel, and the force-bearing plate 331 can be fixedly connected to the first tube 31 and the second tube 32 by riveting, i.e., rivet connection, which is a method of connecting multiple parts by using axial force to thicken the nail rod in the rivet hole of the part and form a nail head. The thickness of the mounting plate 33 is 3mm, which greatly improves the strength of the structure. Figure 6 As shown, when the A-pillar outer panel 11 has been molded, the force plate 331 can be provided to match the installation surface of the A-pillar outer panel 11, thereby saving the cost of repairing the mold of the A-pillar outer panel 11. By changing the structure of the force plate 331, it can be installed and matched with A-pillar outer panels 11 of different profiles, and has high universality.
[0048] See also Figure 5 In some embodiments, the force-bearing plate 331 is provided with a reinforcing structure 332 to strengthen the strength of the force-bearing plate 331. In this way, the structural strength of the force-bearing plate 331 can be strengthened by the reinforcing structure 332 of the force-bearing plate 331, so that the force transmission is more stable.
[0049] See also Figure 5In some embodiments, the reinforcing structure 332 includes a plurality of second reinforcing ribs 3321, the second reinforcing ribs 3321 extend along the width direction of the force-bearing plate 331, and the plurality of reinforcing ribs are arranged along the length direction of the force-bearing plate 331. In this way, the second reinforcing ribs 3321 of the reinforcing structure 332 extend along the width direction of the force-bearing plate 331, and the plurality of reinforcing ribs are arranged along the length direction of the force-bearing plate 331, so that the second reinforcing ribs 3321 are distributed in parallel, which can enhance the structural strength and improve the structural stability.
[0050] See also Figure 2 and Figure 5 In some embodiments, the mounting plate 33 further includes a first side plate 332 and a second side plate 333. The first side plate 332 and the second side plate 333 are respectively located on opposite sides of the force-bearing plate 331. The force-bearing plate 331, the first side plate 332 and the second side plate 333 jointly surround the first tube 31 and the second tube 32. The first side plate 332 is fixedly connected to the first tube 31, and the second side plate 333 is fixedly connected to the second tube 32.
[0051] In this way, by setting the force-bearing plate 331, the first side plate 332 and the second side plate 333 of the mounting plate 33 to jointly surround the first tube 31 and the second tube 32, the first side plate 332 is fixedly connected to the first tube 31, and the second side plate 333 is fixedly connected to the second tube 32, the connection reliability between the mounting plate 33 and the first tube 31 and the second tube 32 can be increased.
[0052] Specifically, the first side plate 332 and the second side plate 333 are respectively located on two opposite sides of the force-bearing plate 331, and the first side plate 332 and the second side plate 333 are arranged along the length direction of the first tube 31 and the second tube 32. The force-bearing plate 331, the first side plate 332 and the second side plate 333 jointly surround the first tube 31 and the second tube 32 to enhance the structural strength of the first tube 31 and the second tube 32. The first side plate 332 is fixedly connected to the first tube 31, and the second side plate 333 is fixedly connected to the second tube 32, which can be fixedly connected by riveting, thereby enhancing the connection reliability.
[0053] See also Figure 4 In some embodiments, the force transmission component 30 further includes a support plate 34, which is detachably connected to the first tube 31 or the second tube 32, and the support plate 34 abuts against the lower end 12. In this way, the support plate 34 in the force transmission component 30 is detachably connected to the first tube 31 or the second tube 32, and the support plate 34 abuts against the lower end 12, so that the first tube 31 or the second tube 32 can be detachably connected to the lower end 12, and the support plate 34 can play a role in installing the first tube 31 or the second tube 32.
[0054] Specifically, the support plate 34 can be processed by sheet metal technology. The sheet metal support plate 34 has a relatively large force-bearing area and can better withstand the force generated by the collision. Figure 7 and Figure 8 As shown, the support plate 34 is pre-hung on five welding screws 341 at the lower end of the A-pillar 10 and fastened by five combination nuts 342. More fastening positions effectively improve the stability of the connection.
[0055] See also Fig. 9 In some embodiments, the length direction of the first tube 31 and the second tube 32 is the same as the height direction of the vehicle body 100. In this way, the length direction of the first tube 31 and the second tube 32 is the same as the height direction of the vehicle body 100, so that the installation of the first tube 31 and the second tube 32 can be more closely fitted to the vehicle body 100.
[0056] For example, Fig. 9 As shown, under certain collision energy conditions, the front tire 120 falls off and hits the A-pillar 10 backwards. Since the A-pillar 10 has a protruding welding edge in the X direction (the length direction of the vehicle), it cannot play a role in collision support and force transmission. By installing a support plate 34 force transmission structure at the lower end of the A-pillar 10, the energy generated by the collision can be effectively absorbed and the energy can be transmitted to the A-pillar 10 and the door sill beam 20, thereby achieving force transmission.
