Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive technology, and in particular to a pillar structure, a body structure, and a vehicle. Background Technology
[0002] In some countries, cars are driven on the right. In these countries, the collision safety requirements specify the right side as the collision side. For example, in ASEAN NCAP (New Car Assessment Program for Southeast Asian Countries), the most widely used new car assessment program in ASEAN, the frontal collision condition for right-hand drive vehicles is a 40% offset collision on the right side at a speed of 64 km / h. Typically, in cars with a front-mounted powertrain, the right side is usually the engine. This means that the collision side changes from the left-hand drive transmission side to the right-hand drive engine side. The collision space and the deformation of the entire vehicle change, and the body structure design needs to be modified accordingly.
[0003] To address the challenges posed by high-speed offset collisions on the right side, the common practice is to reinforce the root of the front longitudinal beam and the lower curved longitudinal beam. This can be achieved by adding upper or inner reinforcing plates to the lower curved longitudinal beam, or by replacing the lower curved longitudinal beam with a higher-strength material or a thicker plate. The aim is for the robust lower curved longitudinal beam to support the front longitudinal beam's compression of the front bulkhead during deformation, thereby reducing the intrusion of the front bulkhead and protecting the occupants.
[0004] However, the above solution addresses the compression of the front bulkhead by reinforcing the lower curved longitudinal beam, which inevitably requires a very strong lower curved longitudinal beam, increasing the vehicle's weight and cost. The upper reinforcing plate of the lower curved longitudinal beam is usually located above the middle floor, which affects the driver's foot space, impacts driving comfort, increases welding difficulty, affects production cycle, and multi-layer plate welding can easily cause poor electrophoresis and other problems such as vehicle body corrosion. Summary of the Invention
[0005] The present invention aims to solve the technical problems mentioned above, which are caused by increasing vehicle weight, cost, and reducing interior space by setting a reinforcing plate on the downward curved longitudinal beam.
[0006] To address the aforementioned technical problems, this application discloses a column structure, comprising:
[0007] The pillar body has its side connected to the front longitudinal beam, one end of the pillar body connected to the A-pillar, and the other end of the pillar body connected to the door sill.
[0008] The first reinforcing member is located in a first region of the column body, which is close to the front longitudinal beam.
[0009] Optionally, the column body includes a first protrusion and a second protrusion spaced apart;
[0010] The area formed between the first protrusion and the second protrusion is the first area;
[0011] The first area has a groove structure.
[0012] Optionally, the first reinforcing member includes a base plate, a first connecting portion, and a second connecting portion;
[0013] The column body includes a second area;
[0014] One end of the base plate is connected to the first connecting part, and the other end of the base plate is connected to the second connecting part;
[0015] The first connecting part and the second connecting part are located on the same side of the base plate;
[0016] The base plate is fixedly connected to the first protrusion and the second protrusion;
[0017] The base plate is at a predetermined distance from the second region, which is the area between the first protrusion and the second protrusion.
[0018] The first connecting portion is connected to one side of the first protrusion and one side of the second protrusion, respectively;
[0019] The second connecting part is connected to the other side of the first protrusion and the other side of the second protrusion, respectively.
[0020] Optionally, a second reinforcing member may also be included;
[0021] The second reinforcing member is located in the third region of the column body;
[0022] The third area is the area near the door sill of the vehicle.
[0023] Optionally, the column body includes a first support structure, a second support structure, and a third support structure;
[0024] The first protrusion and the second protrusion are located on the first support structure;
[0025] One side of the first support structure is connected to the second support structure, and the other side of the first support structure is connected to the third support structure;
[0026] The second support structure and the third support structure are located on the same side of the first support structure;
[0027] The second reinforcing member is fitted and connected to the first support structure, the second support structure, and the third support structure respectively.
[0028] Optionally, the first reinforcing member is fitted and connected to the first region.
[0029] Optionally, the column body is formed from a single plate with a thickness ranging from 1 to 2 millimeters.
[0030] Optionally, the pillar structure is a pillar located near the steering wheel.
[0031] In another aspect, this application discloses a vehicle body structure that includes the aforementioned pillar structure.
[0032] Optionally, it also includes door sills, front longitudinal beams, and lower curved longitudinal beams;
[0033] The connection between the front longitudinal beam and the column body is connected to the downward curved longitudinal beam.
[0034] In another aspect, this application also discloses a vehicle that includes the aforementioned body structure.
[0035] By adopting the above technical solution, the column structure provided in this application has the following beneficial effects:
[0036] Since the pillar structure provided in this application has a first reinforcing member on its main body, and the pillar structure is located below the A-pillar and connected to the door sill, the frame strength under collision conditions can be effectively improved. Furthermore, the first reinforcing member is located in the first area of the pillar body near the front longitudinal beam, which can effectively disperse the collision on the front longitudinal beam and reduce the compression on the front bulkhead. Compared with the prior art, which strengthens the lower bending longitudinal beam, this solution has the advantages of reducing molding costs and not changing the cockpit space.

[0051] like Figure 1 As shown, Figure 1 This is a schematic diagram of the column structure in one optional embodiment of this application. One aspect of this application discloses a column structure 1, which includes a column body 2 and a first reinforcing member 3. The side of the column body 2 is connected to the front longitudinal beam, and one end of the column body 2 is connected to the A-pillar, while the other end is connected to the door sill. The first reinforcing member 3 is disposed in a first region 21 of the column body 2, which is close to the front longitudinal beam.
[0052] Since the pillar structure 1 provided in this application has a first reinforcing member 3 on its main body, and the pillar structure 1 is a pillar located below the A-pillar and connected to the door sill, the frame strength under collision conditions can be effectively improved. Furthermore, the first reinforcing member 3 is located on the first region 21 of the pillar body 2 near the front longitudinal beam, which can effectively disperse the collision on the front longitudinal beam and reduce the compression on the front bulkhead. Compared with the prior art, which strengthens the lower bending longitudinal beam, this solution has the advantages of reducing molding costs and not changing the cockpit space.
[0053] In one alternative implementation, such as Figure 2 As shown, Figure 2 This is a schematic diagram of the column structure in another optional embodiment of this application. The column body 2 includes a first protrusion 22 and a second protrusion 23 spaced apart; the area formed between the first protrusion 22 and the second protrusion 23 is the first region 21; the first region 21 is a groove structure.
[0054] In one alternative implementation, such as Figure 3As shown, Figure 3 This is a schematic diagram of the structure of the first reinforcing member of this application. The first reinforcing member 3 includes a base plate 31, a first connecting part 32, and a second connecting part 33; the column body 2 includes a second region 24; one end of the base plate 31 is connected to the first connecting part 32, and the other end of the base plate 31 is connected to the second connecting part 33; the first connecting part 32 and the second connecting part 33 are located on the same side of the base plate 31; the base plate 31 is fixedly connected to the first protrusion 22 and the second protrusion 23; there is a preset distance between the base plate 31 and the second region 24, and the second region 24 is the region between the first protrusion 22 and the second protrusion 23; the first connecting part 32 is connected to one side of the first protrusion 22 and one side of the second protrusion 23 respectively; the second connecting part 33 is connected to the other side of the first protrusion 22 and the other side of the second protrusion 23 respectively.
[0055] In other words, in this embodiment, the first reinforcing member 3 and the column body 2 form a cavity structure, which can more effectively absorb and disperse the force generated by the collision of the front longitudinal beam.
[0056] In another alternative embodiment, the first reinforcement 3 is fitted and connected to the first region 21.
[0057] In one alternative implementation, such as Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of the second reinforcing member of this application. The pillar structure 1 also includes a second reinforcing member 4; the second reinforcing member 4 is disposed in a third region of the pillar body 2; the third region is the region near the door sill 6, thereby further increasing the lightness of the pillar structure 1, thereby improving the resistance to wheel collisions.
[0058] In one alternative implementation, such as Figure 5 As shown, Figure 5 This is a schematic diagram of the column structure in another optional embodiment of this application. The column body 2 includes a first support structure 25, a second support structure 26, and a third support structure 27; the first protrusion 22 and the second protrusion 23 are located on the first support structure 25; one side of the first support structure 25 is connected to the second support structure 26, and the other side of the first support structure 25 is connected to the third support structure 27; the second support structure 26 and the third support structure 27 are located on the same side of the first support structure 25; the second reinforcing member 4 is respectively attached to and connected to the first support structure 25, the second support structure 26, and the third support structure 27.
[0059] In one alternative embodiment, the column body 2 is formed from a single plate with a thickness ranging from 1 to 2 millimeters.
[0060] In one alternative embodiment, the pillar structure 1 is a pillar near the steering wheel, and optionally, the steering wheel is located on the left or right side of the cockpit.
[0061] Optionally, the connection between the various components described above can be any one of screwing, welding, or bonding.
[0062] This application also discloses a vehicle body structure, such as Figure 6-9 As shown, Figure 6 This is a partial schematic diagram of an optional vehicle body structure according to this application; Figure 7 This is a partial schematic diagram of another alternative vehicle body structure in this application; Figure 8 This is a partial schematic diagram of another alternative vehicle body structure in this application; Figure 9 This is a partial schematic diagram of another optional vehicle body structure according to this application. The vehicle body structure includes the aforementioned pillar structure 1.
[0063] In one alternative implementation, such as Figure 6-9 As shown, the vehicle body structure also includes a door sill 6, a front longitudinal beam 5, and a lower curved longitudinal beam 10; the connection between the front longitudinal beam 5 and the pillar body 2 is connected to the lower curved longitudinal beam 10. As can be seen from the above description, the side of the pillar body 2 is connected to the front longitudinal beam 5, and one end of the pillar body 2 is connected to the A-pillar, and the other end of the pillar body 2 is connected to the door sill 6.
[0064] like Figure 9 As shown, the vehicle body structure also includes a diagonal support 7 and a front bulkhead 9. The front bulkhead 9 is connected to the pillar structure 1. The diagonal support 7 is located in a through hole on the front bulkhead 9. The diagonal support 7 is connected to the pillar structure 1 and the front longitudinal beam 5, so that the force generated by the collision of the front longitudinal beam 5 can be transmitted to the pillar structure 1 through the diagonal support 7. This force transmission can disperse the collision force, thereby reducing the compression of the front bulkhead 9.
[0065] In another aspect, this application also discloses a vehicle that includes the aforementioned body structure.
[0066] In summary, one possible application scenario for the pillar structure 1 provided in this application is as follows: when the wheel 8 is impacted, the pillar structure 1 strengthens the first type of support force on the front longitudinal beam 5 through the first reinforcing member 3, effectively bearing the impact force in the direction of the wheel 8. Moreover, the downward curved longitudinal beam 10 can also provide a second type of support force to the front longitudinal beam 5. A third type of support force is provided to the front longitudinal beam 5 through the door sill 6, the second reinforcing member 4, and the pillar body 2. It can be seen that the force on the downward curved longitudinal beam 10 can be effectively dispersed through the combination of the above three support forces. There is no need to design an additional reinforcing plate on the upper part of the downward curved longitudinal beam 10, while simultaneously providing support to the root of the front longitudinal beam 5 and reducing the intrusion of the front panel 9. Not only is the molding process simple, but it can also effectively reduce weight and cost. Furthermore, the overall structure of the pillar structure 1 is simple and does not occupy the foot space of the driver and passengers.
[0067] The above description is only an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
