Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and in particular to a column structure and a vehicle. Background Technology

[0002] With increasing global focus on environmental protection and energy efficiency, the new energy vehicle market is experiencing rapid growth. The widespread adoption of electric vehicles, hybrid vehicles, and other new energy vehicle models has not only driven technological innovation in the automotive industry but also changed consumer expectations regarding vehicle performance. Against this backdrop, vehicle safety and comfort have become key concerns for consumers.

[0003] Improving vehicle safety performance, especially in the event of rollover or crush accidents, is crucial for protecting occupants. The B-pillar, as a vital component of the vehicle body structure, directly impacts the vehicle's performance in an accident due to its strength and rigidity. The design of the B-pillar must not only meet collision safety standards but also strike a balance between lightweighting and strength. While traditional steel offers high strength, its weight is significant, hindering vehicle energy efficiency optimization. Utility Model Content

[0004] In view of this, the present application provides a pillar structure and a vehicle, in which a hollow installation space is formed within the pillar body, and a reinforcing member is provided within the installation space to enhance the structural strength and impact resistance of the pillar body. The reinforcing part of the reinforcing member improves the compressive and bending resistance of the pillar body, thereby reducing the weight of the vehicle while increasing its structural strength.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a pillar structure disposed on the body of a vehicle, the pillar structure comprising:

[0007] The column body includes an inner plate and an outer plate, wherein a portion of the structure of one of the inner plate and the outer plate is recessed in a direction away from the other, forming an installation space;

[0008] A reinforcing member is provided in the installation space. The reinforcing member has a cavity extending along the height direction of the vehicle, and multiple reinforcing parts are spaced apart in the cavity along the height direction of the vehicle.

[0009] The column structure of this utility model features a hollow structure with an installation space for the main body of the column. Reinforcing members are housed within this installation space, and multiple reinforcing sections are incorporated within the cavities of the reinforcing members. On one hand, this helps reduce vehicle weight, meeting lightweight requirements. On the other hand, the cavities of the reinforcing members help absorb and disperse external impact forces on the main body of the column, improving the overall deformation resistance of the column structure. The inclusion of reinforcing sections also further enhances the compressive and bending resistance of the column structure, improving vehicle safety during operation.

[0010] In some embodiments, the reinforcement includes a first side plate, a second side plate, and a mounting plate, the first side plate and the second side plate being spaced apart along the length of the vehicle and connected by the mounting plate, the first side plate, the second side plate, and the mounting plate defining the cavity.

[0011] Thus, the combined design of the first side plate, the second side plate, and the mounting plate forms a stable frame structure, significantly improving the column's impact and deformation resistance. This design allows for the installation of multiple reinforcing sections within the cavity as needed to further enhance the column's strength and rigidity.

[0012] According to some embodiments of the present invention, the reinforcing part includes a reinforcing protrusion, which protrudes from the mounting plate toward the opening of the cavity, and the roots of two adjacent reinforcing protrusions are connected along the height direction of the vehicle body.

[0013] In this way, multiple reinforcing protrusions are connected to form a continuous protrusion-recess structure, which helps to evenly distribute the stress on the column structure throughout the entire column structure, reduce local stress concentration, improve the reliability of the column structure, further improve the impact resistance and deformation resistance of the column structure, and ensure better protection in a collision.

[0014] According to some embodiments of the present invention, the reinforcing member extends obliquely downward along the height direction of the vehicle, and / or,

[0015] Along the height direction of the vehicle from top to bottom, the distance between the first side panel and the second side panel gradually increases.

[0016] Thus, through the inclined design of the reinforcing member and the variation in the spacing between the first and second side plates, the overall structure of the reinforcing member is made continuous and smooth, allowing it to evenly distribute the impact force received. This enables the pillar structure to better adapt to the mechanical requirements of the vehicle under different operating conditions, improving overall stability. Simultaneously, the inclined design of the reinforcing member and the variation in the spacing between the first and second side plates allow the pillar structure to more effectively disperse and absorb impact forces, providing better occupant protection.

[0017] According to some embodiments of this utility model, the reinforcing member is fixedly connected to the outer plate, a connecting cross plate is provided at the top of the reinforcing member, and the inner plate is fixedly connected to the upper beam of the vehicle through the connecting cross plate.

[0018] In this way, the connection between the reinforcing member and the outer plate, the connection between the connecting plate and the reinforcing member, and the fixed connection between the inner plate and the upper beam via the connecting plate create a monolithic structure for the main column, forming a continuous stress transmission path. This helps improve the overall structural strength of the main column. Furthermore, the connecting plate ensures more even stress distribution on the reinforcing member, reducing localized stress concentration and improving its durability.

[0019] According to some embodiments of this utility model, the inner plate is provided with a first mounting hole, the connecting cross plate is provided with a second mounting hole corresponding to the first mounting hole, and the upper beam is provided with a third mounting hole corresponding to the second mounting hole. The connector passes through the first mounting hole, the second mounting hole and the third mounting hole in sequence to fix the inner plate to the upper beam.

[0020] Thus, the alignment design of the multi-layered first mounting hole, second mounting hole, and third mounting hole helps to ensure the precise connection between the inner plate, connecting cross plate, and upper beam, thereby guaranteeing the overall strength of the column structure.

[0021] According to some embodiments of the present invention, the column structure further includes:

[0022] The third side plate is disposed on the connecting cross plate. The third side plate has a first supporting end face on the side of the inner plate facing the outer plate and a second supporting end face on the upper beam.

[0023] Thus, by setting up a third side plate, a closed connection structure is formed at the upper end of the column body and the upper beam, which helps improve the stability of stress transmission in the column structure. Furthermore, the third side plate provides additional support for the column structure, further enhancing the overall strength and rigidity of the column body. This multi-layered support structure helps to evenly distribute the stress on the column structure, reducing local stress concentration and improving the durability of the column structure.

[0024] In some embodiments, a portion of the outer panel is recessed in a direction away from the inner panel to form the mounting space, the reinforcing member is fixedly disposed in the mounting space, and the mounting plate of the reinforcing member is disposed opposite to the inner panel, and the inner panel is fixedly connected to the outer panel.

[0025] In this way, the recessed design of the outer panel and the fixed configuration of the reinforcements form a stable structural frame, improving the overall strength of the column structure. The recessed design of the outer panel provides an effective installation space, allowing the reinforcements to be compactly integrated into the column structure, thereby enabling the column structure to effectively absorb and disperse impact forces, providing better protection for vehicle occupants.

[0026] According to some embodiments of the present invention, the reinforcing member is embedded in the installation space, and the reinforcing member is provided with multiple welding parts on both sides along the front-rear direction of the vehicle. The inner plate is provided with a positioning groove corresponding to the welding part on the end face facing the outer plate. The welding part is located in the positioning groove, and the welding part is welded to the outer plate and welded to the inner wall of the positioning groove.

[0027] Thus, the design of the positioning groove ensures precise positioning of the welded parts, reduces errors during the welding process, and improves the reliability of the connection between the reinforcing member and the inner and outer panels. Through the embedded design of the reinforcing member and multi-point welding with the inner and outer panels, a stable structural frame is formed in the main column, significantly improving the overall strength of the column structure and contributing to enhanced vehicle safety.

[0028] On the other hand, embodiments of this utility model also provide a vehicle, the vehicle including: a body; the above-mentioned pillar structure, the pillar structure being disposed on the body.

[0029] The vehicle of this invention, due to the aforementioned pillar structure, improves the compressive and bending resistance of the pillar structure through multiple reinforcing parts, thereby enhancing vehicle safety during operation. Simultaneously, the reinforcing member forms a continuous stress transmission path with the upper beam via a connecting crossplate at the top. The multi-point welding design between the reinforcing member and the inner and outer panels enhances the overall integrity of the pillar body, enabling the vehicle to more effectively absorb and disperse impact forces during a collision, reducing the impact on the passenger compartment.

[0046] Improving vehicle safety performance, especially in the event of rollover or crush accidents, is crucial for protecting occupants. The B-pillar, as a vital component of the vehicle body structure, directly impacts the vehicle's performance in an accident due to its strength and rigidity. The design of the B-pillar must not only meet collision safety standards but also strike a balance between lightweighting and strength. While traditional steel offers high strength, its weight is significant, hindering vehicle energy efficiency optimization.

[0047] In view of this, the present utility model provides a pillar structure and a vehicle, in which a hollow installation space is formed inside the pillar body, and a reinforcing member is provided in the installation space to enhance the structural strength and impact resistance of the pillar body. The reinforcing part of the reinforcing member improves the compressive and bending resistance of the pillar body, thereby making the vehicle lighter while improving the structural strength of the vehicle.

[0048] refer to Figures 1 to 5 In a first aspect, embodiments of this application provide a pillar structure 100, which is disposed on the body of a vehicle. The pillar structure 100 may include a pillar body 110 and a reinforcing member 120.

[0049] The column body 110 includes an inner plate 111 and an outer plate 112. A portion of the structure of one of the inner plate 111 and the outer plate 112 is recessed away from the other to form an installation space. For example, a portion of the structure of the inner plate 111 may be recessed away from the outer plate 112 to form an installation space, or a portion of the structure of the outer plate 112 may be recessed away from the inner plate 111 to form an installation space. This not only helps to reduce weight, but also forms an installation space for accommodating other components (such as the reinforcing member 120).

[0050] Optionally, the inner panel 111 and the outer panel 112 can be made of high-strength steel, aluminum alloy or other composite materials to meet the needs of different vehicle models.

[0051] The reinforcing member 120 is provided in the installation space. The reinforcing member 120 has a cavity 121 extending along the height direction of the vehicle. Through the cavity 121, the reinforcing member 120 can effectively absorb and disperse external impact forces and improve the overall deformation resistance of the column structure 100.

[0052] refer to Figure 2 Multiple reinforcing parts 122 are provided at intervals along the height direction of the vehicle inside the cavity 121. For example, the reinforcing parts 122 can be reinforcing ribs. By providing multiple reinforcing ribs, multiple stress transmission paths are provided for the reinforcing member 120, which helps to evenly disperse the impact force received by the column structure 100 and improve the structural strength of the column structure 100. Alternatively, the reinforcing parts 122 can also be protrusions protruding outward from inside the cavity 121. The protrusions are continuous and form a wave-like force transmission structure extending from top to bottom, which helps to avoid stress concentration on the reinforcing member 120 and improve the structural strength of the column structure 100.

[0053] The column structure 100 of this utility model has a hollow structure with an installation space for the main body 110. A reinforcing member 120 is disposed within the installation space, and multiple reinforcing parts 122 are provided within the cavity 121 of the reinforcing member 120. On the one hand, this helps reduce the weight of the vehicle body, meeting the vehicle's lightweight requirements. On the other hand, the cavity 121 of the reinforcing member 120 helps absorb and disperse external impact forces received by the main body 110, improving the overall deformation resistance of the column structure 100. The addition of the reinforcing parts 122 also helps to further improve the compressive and bending resistance of the column structure 100, enhancing vehicle safety during driving.

[0054] Continue to refer to Figure 2In some embodiments, the reinforcing member 120 includes a first side plate 120a, a second side plate 120b, and a mounting plate 120c. The first side plate 120a and the second side plate 120b are spaced apart along the length of the vehicle and are connected by the mounting plate 120c. The first side plate 120a, the second side plate 120b, and the mounting plate 120c define a cavity 121. The cavity 121 is designed to help absorb and disperse impact forces from outside the vehicle, thereby improving the deformation resistance of the pillar structure 100. The first side plate 120a, the second side plate 120b, and the mounting plate 120c can be fixed by welding, or they can be an integral structure formed by sheet metal processing of the reinforcing member 120 to create a recessed portion of the reinforcing member 120, thus forming a receiving cavity. Meanwhile, in order to improve the smoothness of the lines at the connection between the first side plate 120a and the second side plate 120b and the mounting plate 120c respectively, and to avoid stress concentration, the first side plate 120a and the second side plate 120b can be tilted relative to each other.

[0055] Thus, the combined design of the first side plate 120a, the second side plate 120b, and the mounting plate 120c forms a stable frame structure, significantly improving the column's impact and deformation resistance. This design allows for the installation of multiple reinforcing sections 122 within the cavity 121 as needed, further enhancing the column's strength and rigidity.

[0056] According to some embodiments of this utility model, the reinforcing part 122 includes a reinforcing protrusion that protrudes from the mounting plate 120c toward the opening of the cavity 121, and the roots of two adjacent reinforcing protrusions are connected along the height direction of the vehicle body. Exemplarily, the reinforcing protrusion can be an arc-shaped protrusion, or it can be a boss structure, with a recess-like structure formed between two adjacent reinforcing protrusions. Thus, multiple reinforcing protrusions connected to form a continuous protrusion-recess structure (such as a continuous wave-shaped structure) helps to evenly distribute the stress on the pillar structure throughout the entire pillar structure 100, reducing local stress concentration, improving the reliability of the pillar structure 100, and further improving the impact resistance and deformation resistance of the pillar structure, providing better protection in a collision.

[0057] Furthermore, to enhance the vehicle's aesthetics, the vehicle's pillars typically have a certain curvature. Correspondingly, the reinforcing member 120 may also have a certain curvature, resulting in the mounting plate 120c having a certain curvature. In other words, the depth of the cavity 121 varies at different points along the vehicle's height. Accordingly, the height of the reinforcing protrusion can be adjusted according to the depth of the cavity 121 at the corresponding location. This makes the stress distributed in the reinforcing member 120 more uniform, improving the structural stability of the pillar structure 100.

[0058] In one specific embodiment, the top of the reinforcing protrusion can protrude to the opening of the cavity 121. Since the depth of the cavity 121 is different at different locations, the protrusion height of the corresponding reinforcing protrusion is different.

[0059] Understandably, in other embodiments of this utility model, the reinforcing part 122 also includes reinforcing ribs. The reinforcing ribs are fixedly disposed on the mounting plate 120c, and are fixedly connected to the first side plate 120a and the second side plate 120b on both sides along the front-rear direction of the vehicle, respectively. The reinforcing ribs improve the overall integrity of the reinforcing member 120, enabling it to effectively disperse and transfer stress, thereby improving the overall rigidity and strength of the pillar structure 100. Thus, by setting the reinforcing part 122 as a reinforcing rib, it is beneficial to evenly distribute the stress on the pillar structure 100 throughout the entire pillar structure 100, reducing local stress concentration, improving the reliability of the pillar structure 100, and further enhancing the impact resistance and deformation resistance of the pillar structure 100, ensuring better protection in a collision.

[0060] According to some embodiments of the present invention, the reinforcing member 120 extends downward at an angle along the height direction of the vehicle, so that the reinforcing member 120 can effectively guide and disperse the impact force, so that the stress is transmitted along a more favorable path, thereby reducing local stress concentration, enhancing the deformation resistance of the column structure 100, and thus improving the overall structural durability.

[0061] Along the height direction of the vehicle from top to bottom, the distance between the first side plate 120a and the second side plate 120b gradually increases, so that the reinforcing member 120 provides different stiffness and strength to the column structure 100 at different height positions to adapt to the dynamic requirements of the vehicle structure.

[0062] Thus, through the inclined design of the reinforcing member 120 and the variation in the spacing between the first side plate 120a and the second side plate 120b, the overall structure of the reinforcing member 120 is made continuous and smooth, allowing it to evenly distribute the impact force. This enables the pillar structure 100 to better adapt to the mechanical requirements of the vehicle under different operating conditions, improving overall stability. Simultaneously, the inclined design of the reinforcing member 120 and the variation in the spacing between the first side plate 120a and the second side plate 120b allow the pillar structure 100 to more effectively disperse and absorb impact forces, providing better occupant protection.

[0063] According to some embodiments of this utility model, the reinforcing member 120 is fixedly connected to the outer plate 112. Exemplarily, the reinforcing member 120 can be fixedly connected to the outer plate 112 using fasteners such as bolts and screws, or the reinforcing member 120 can be fixedly connected to the outer plate 112 by welding. This fixed connection achieves integration between the reinforcing member 120 and the outer plate 112. This connection method ensures that the reinforcing member 120 can effectively transmit and disperse external impact forces, improving the overall rigidity and strength of the column structure 100.

[0064] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 A connecting plate 123 is provided at the top of the reinforcing member 120, and the inner plate 111 is fixedly connected to the upper beam 210 of the vehicle through the connecting plate 123. The design of the connecting plate not only provides additional structural support, but also provides a stable foundation for the connection between the inner plate 111 and the upper beam 210 of the vehicle. Through the connecting plate 123, the inner plate 111 is fixedly connected to the upper beam 210 of the vehicle. This connection method helps to form a complete frame structure, improving the overall stability and deformation resistance of the column.

[0065] Thus, the reinforcing member 120 is connected to the outer plate 112, the connecting horizontal plate 123 is connected to the reinforcing member 120, and the inner plate 111 is fixedly connected to the upper beam 210 through the connecting horizontal plate 123, making the column body 110 an integral structure and forming a continuous stress transmission path, which is beneficial to improving the overall structural strength of the column body 110. In addition, the setting of the connecting horizontal plate 123 also makes the stress transmission on the reinforcing member 120 more uniform, reduces local stress concentration, and improves the durability of the reinforcing member 120.

[0066] According to some embodiments of this utility model, the inner plate 111 is provided with a first mounting hole, the connecting cross plate 123 is provided with a second mounting hole corresponding to the first mounting hole, and the upper beam 210 is provided with a third mounting hole corresponding to the second mounting hole. The connector passes through the first mounting hole, the second mounting hole, and the third mounting hole in sequence to fix the inner plate 111 and the upper beam 210 together. This connection method not only provides a high-strength fixing effect but also ensures structural stability under vehicle dynamic conditions. Thus, the alignment design of the multi-layered first mounting hole, second mounting hole, and third mounting hole helps to ensure the precise connection between the inner plate 111, the connecting cross plate 123, and the upper beam 210, thereby ensuring the overall strength of the column structure 100.

[0067] Alternatively, the connectors can be fasteners such as bolts, screws, and pins, which facilitates standardization of the production process and saves production costs.

[0068] refer to Figure 2, Figure 3 , Figure 4 and Figure 5 According to some embodiments of the present invention, the column structure 100 may further include a third side plate 124, the third side plate 124 being disposed on the connecting horizontal plate 123, the third side plate 124 having a first supporting end face supporting the inner plate 111 on the side facing the outer plate 112, and the third side plate 124 having a second supporting end face supporting the upper beam 210.

[0069] Thus, by setting the third side plate 124, a closed connection structure is formed at the connection between the upper end of the column body 110 and the upper beam 210, which helps to improve the stability of stress transmission on the column structure 100. Furthermore, the third side plate 124 also provides an additional support structure for the column structure 100, further improving the overall strength and rigidity of the column body 110. This multi-layered support structure helps to evenly distribute the stress on the column structure 100, reduces local stress concentration, and improves the durability of the column structure 100.

[0070] In some embodiments, a portion of the surface of the outer plate 112 is recessed in a direction away from the inner plate 111 to form an installation space. The reinforcing member 120 is fixedly disposed in the installation space, and the mounting plate 120c of the reinforcing member 120 is disposed opposite to the inner plate 111. The inner plate 111 and the outer plate 112 are fixedly connected.

[0071] Thus, through the recessed design of the outer panel 112 and the fixed configuration of the reinforcing member 120, a stable structural frame is formed, improving the overall strength of the column structure 100. The recessed design of the outer panel 112 provides an effective installation space, allowing the reinforcing member 120 to be compactly integrated into the column structure 100, thereby enabling the column structure 100 to effectively absorb and disperse impact forces, providing better protection for the occupants.

[0072] According to some embodiments of the present invention, the reinforcing member 120 is embedded in the installation space. The reinforcing member 120 has multiple welding parts 125 on both sides along the front-rear direction of the vehicle. The inner plate 111 has a positioning groove 1111 corresponding to the welding part 125 on the end face facing the outer plate 112. The welding part 125 is located in the positioning groove 1111. The welding part 125 is welded to the outer plate 112 and welded to the inner wall of the positioning groove 1111.

[0073] Thus, the design of the positioning groove 1111 ensures the precise positioning of the welding part 125, reduces errors during the welding process, and improves the reliability of the connection between the reinforcing member 120 and the inner plate 111 and the outer plate 112. Through the embedded design of the reinforcing member 120 and the multi-point welding between it and the inner plate 111 and the outer plate 112, the column body 110 forms a stable structural frame, significantly improving the overall strength of the column structure 100 and contributing to improved vehicle safety.

[0074] Optionally, the welding part 125 can be a welding plate, which has a large mating area with the inner plate 111 and the outer plate 112, which is beneficial to improving the stability of welding. Alternatively, the welding part 125 can also be a protrusion that matches the positioning groove 1111, which has high positioning accuracy and is beneficial to improving the continuity of the column structure 100 in the stress dispersion and transmission process, thereby improving the safety of the vehicle.

[0075] On the other hand, embodiments of the present invention also provide a vehicle, which may include a vehicle body and the aforementioned pillar structure 100, wherein the pillar structure 100 is disposed on the vehicle body.

[0076] Specifically, the vehicle in this application can refer to large automobiles, small automobiles, special-purpose vehicles, etc. For example, according to vehicle type, the automobile in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0077] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.

[0078] The vehicle of this utility model, due to the aforementioned pillar structure 100, improves the compressive and bending resistance of the pillar structure 100 through multiple reinforcing parts 122 provided by the reinforcing member 120, thereby enhancing the vehicle's safety during operation. Simultaneously, the reinforcing member 120 forms a continuous stress transmission path with the upper beam 210 via the connecting cross plate 123 at its top. The multi-point welding design between the reinforcing member 120 and the inner panel 111 and outer panel 112 helps improve the overall integrity of the pillar body 110, enabling the vehicle to more effectively absorb and disperse impact forces during a collision, reducing the impact on the passenger compartment.

[0079] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
