Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicles, and in particular to a side panel reinforcement structure for a vehicle, a side panel assembly, and a vehicle. Background Art

[0002] In order to improve the strength of the vehicle body and limit the intrusion of external collision forces into the vehicle cabin in the event of a head-on collision, side collision, or top crush, and to provide better protection for the occupants in the vehicle, corresponding reinforcement structures are usually set in the vehicle body.

[0003] For example, the reinforcement structure at the side of the vehicle's front door is roughly annular, and the inner ring cavity of the reinforcement structure corresponds to the front door opening of the vehicle. The reinforcement structure, such as the A-pillar, B-pillar and door sill area, is strengthened so that when the vehicle collides, the external force of the collision can be absorbed by the above-mentioned reinforcement structure, thereby reducing the magnitude of the external force transmitted to the driver and passengers.

[0004] However, the reinforcement structure at the side panel of the front door of the vehicle in the related art cannot meet the collision protection requirements, resulting in safety hazards when driving the vehicle. Summary of the invention

[0021] In some embodiments, the B-pillar reinforcement section includes a B-pillar first reinforcement section and a B-pillar second reinforcement section;

[0022] The first reinforcement section of the B-pillar is connected between the rocker reinforcement section and the second reinforcement section of the B-pillar, and one end of the second reinforcement section of the B-pillar away from the first reinforcement section of the B-pillar is connected to the A-pillar reinforcement section.

[0023] In some embodiments, the second reinforcement section of the B-pillar includes an upper reinforcement section of the B-pillar and a lower reinforcement section of the B-pillar;

[0024] The B-pillar upper reinforcement section is connected between the A-pillar reinforcement section and the B-pillar lower reinforcement section, and one end of the B-pillar lower reinforcement section away from the B-pillar upper reinforcement section is connected to the B-pillar first reinforcement section.

DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0037] Reference Figures 1 to 3 As shown, this embodiment provides a side panel reinforcement structure for a vehicle, which is applied to the side panel of the vehicle as a part of the side panel assembly of the vehicle to strengthen the strength of the side panel.

[0038] Specifically, the side panel assembly includes a side panel and the above-mentioned vehicle side panel reinforcement structure. The side panel is usually connected to the outside of the above-mentioned vehicle side panel reinforcement structure to decorate and protect the vehicle side panel reinforcement structure. Exemplarily, the side panel includes a side panel inner panel and a side panel outer panel connected to each other, the side panel outer panel is connected to the side of the vehicle side panel reinforcement structure away from the vehicle cabin, and the side panel inner panel is connected to the side of the vehicle side panel reinforcement structure facing the vehicle cabin.

[0039] Reference Figures 1 to 3 As shown, the vehicle side wall reinforcement structure specifically includes at least three side wall reinforcements 10. At least three side wall reinforcements 10 are connected in sequence and enclosed to form an annular structure 101, and at least two of the side wall reinforcements 10 have different materials. Specifically, the annular structure 101 formed by connecting at least three side wall reinforcements 10 in sequence is the door opening of the vehicle. Exemplarily, for example, at least part of the side wall reinforcements 10 can be made of metal.

[0040] Exemplarily, when the above-mentioned side wall reinforcement structure for a vehicle is applied to the side wall position of the front door of the vehicle, the annular structure 101 corresponds to the front door opening of the vehicle, for example, at least three side wall reinforcement members 10 may include at least an A-pillar reinforcement section 1, a B-pillar reinforcement section 2 and a door sill reinforcement section 3 connected in sequence. Among them, the A-pillar reinforcement section 1 is at least used to correspond to the A-pillar of the vehicle. The B-pillar reinforcement section 2 is at least used to correspond to the B-pillar of the vehicle. The door sill reinforcement section 3 is at least used to correspond to the door sill area of ​​the vehicle.

[0041] By making the materials corresponding to at least two side panel reinforcements 10 among all the side panel reinforcements 10 different, at least two side panel reinforcements 10 in the annular structure 101 are made of different materials, so as to form at least two segments with different strengths in the circumferential direction of the annular structure, so that each side panel reinforcement 10 provides corresponding collision protection for the corresponding position of the vehicle side panel, thereby achieving more refined control of the collision protection and energy absorption performance of the vehicle side panel reinforcement structure, and improving the safety of the vehicle when driving.

[0042] For example, since the A-pillar reinforcement section 1 of the vehicle is the connecting part connecting the roof and the front engine compartment at the left and right front of the vehicle, when the vehicle is hit head-on, the impact force will be quickly transmitted to the A-pillar reinforcement section 1 through the front bumper, the engine compartment side beam, etc., so the A-pillar reinforcement section 1 is a wall supporting the strength of the cockpit. The higher the strength of the A-pillar reinforcement section 1, the stronger the anti-collision ability of the vehicle. Therefore, the A-pillar reinforcement section 1 can be made of a material with higher strength, which can reduce the possibility of the A-pillar reinforcement section 1 absorbing energy and deforming when the vehicle collides to a certain extent, and improve the safety of the drivers and passengers in the cockpit.

[0043] For another example, the B-pillar reinforcement section 2 can be made of a material with lower strength. When the vehicle expands laterally, the B-pillar reinforcement section 2 can absorb energy and deform to consume and disperse the collision force to a certain extent, thereby weakening the collision energy transmitted to the cockpit to a certain extent, thereby ensuring the safety of the driver and passengers in the cockpit to a certain extent.

[0044] Specifically, during the manufacturing process of the vehicle side panel reinforcement structure, each side panel reinforcement 10 can be made of a material with corresponding strength according to the different collision or extrusion locations that may occur on the vehicle, such as the different collision protection requirements at different positions of the annular structure 101 in the event of a frontal collision, side collision, or top extrusion.

[0045] For example, in a specific implementation, the thickness of each side panel reinforcement 10 can be the same, or at least two side panel reinforcements 10 can have different thicknesses. At the same time, for the same side panel reinforcement 10, it can be of equal thickness or of variable cross-section and unequal thickness design.

[0046] Of course, in other embodiments, the above-mentioned vehicle side wall reinforcement structure may also be applied to the side wall position of the vehicle's rear door. In this case, the annular structure corresponds to the rear door opening of the vehicle.

[0047] The vehicle side wall reinforcement structure provided in this embodiment is provided with at least three side wall reinforcements 10; the at least three side wall reinforcements 10 are sequentially connected and enclosed to form an annular structure 101, and at least two of the side wall reinforcements 10 have corresponding materials different from each other. In this way, at least two side wall reinforcements 10 in the annular structure 101 are made of different materials, so as to form at least two sections with different strengths in the circumferential direction of the annular structure 101, so that each side wall reinforcement 10 provides corresponding collision protection for the corresponding position of the vehicle side wall. For example, when at least three side reinforcements include at least an A-pillar reinforcement section 1, a B-pillar reinforcement section 2 and a door sill reinforcement section 3 connected in sequence, the A-pillar reinforcement section 1 can be made of a material with higher strength to increase the strength of the A-pillar reinforcement section 1, thereby avoiding deformation of the A-pillar reinforcement section when the vehicle has a head-on collision, thereby protecting the driver and passengers to a certain extent; for example, the B-pillar reinforcement section 2 can also be made of a material with lower strength than the A-pillar reinforcement section 1 to reduce the strength of the B-pillar reinforcement section 2 accordingly, thereby allowing the B-pillar reinforcement section 2 to absorb the external force of the collision to a certain extent and deform to absorb energy when the vehicle has a side collision, thereby weakening the collision energy transmitted to the cockpit, thereby protecting the driver and passengers to a certain extent, thereby achieving more refined control of the collision protection and energy absorption performance of the vehicle side reinforcement structure in the circumferential direction of the annular structure 101, thereby improving the safety of the vehicle when driving.

[0048] In some embodiments, among all the side enclosure reinforcements 10 , at least two side enclosure reinforcements 10 have materials corresponding to different grades.

[0049] The material grade refers to a way of identifying materials using numbers, letters or symbols, etc. Different grades represent their unique chemical composition, physical properties, etc. Among them, the above-mentioned physical properties include strength (specifically yield strength and tensile strength), etc. Generally, the higher the grade, the higher the strength of the corresponding material.

[0050] By making the materials corresponding to at least two side panel reinforcements 10 have different grades, it is convenient to form at least two segments with different strengths in the circumferential direction of the annular structure 101, so that each side panel reinforcement 10 provides corresponding collision protection for the corresponding position of the vehicle side panel, thereby achieving more refined control of the collision protection and energy absorption performance of the vehicle side panel reinforcement structure in the circumferential direction of the annular structure 101, thereby improving the safety of the vehicle when driving.

[0051] In some embodiments, all the side panel reinforcements 10 are welded and connected to form a preformed structure, and the side panel reinforcement structure for a vehicle is formed by hot stamping the preformed structure.

[0052] That is to say, all the side panel reinforcements 10 are first connected by welding to form a whole, and then the whole is hot stamped through a stamping die, so that the vehicle side panel reinforcement structure forms a corresponding three-dimensional structure and achieves ideal tensile strength and yield strength. This can reduce the number of stamping dies and the number of hot stamping times required for the molding of the vehicle side panel reinforcement structure to a certain extent, thereby not only realizing manufacturing integration to a certain extent and reducing production costs, but also improving the vehicle's body-in-white manufacturing efficiency, thereby improving the vehicle's production efficiency.

[0053] In some embodiments, all the side panel reinforcements 10 are connected by laser tailor welding (TWB) to form the above-mentioned preformed structure. That is, when welding two adjacent side panel reinforcements 10, the two side panel reinforcements 10 are aligned and then the welding operation is performed.

[0054] This arrangement utilizes the characteristic of laser welding that it only requires aligning the parts to be welded, without reserving overlapping edges for the parts to be welded and performing spot welding through the overlapping edges. In other words, the above arrangement can save the weight of the overlapping edges to a certain extent, reduce the weight and cost of the side panel reinforcement structure for the vehicle to a certain extent, and is conducive to the lightweight design of the vehicle.

[0055] In some embodiments, the side reinforcements 10 can be steel parts formed by hot stamping, for example. That is, the side reinforcements 10 are hot stamped steel plates. Specifically, when making hot stamped steel plates, the raw materials are heated and softened before being stamped into a molded product, and the molded product is quickly cooled in the stamping die. Such a quenching effect can improve its strength, thereby helping to reduce the thickness of the side reinforcements 10, which is beneficial to reducing the weight of the vehicle, improving the vehicle's endurance and fuel efficiency, etc., and can also improve the vehicle's driving performance and driving safety to a certain extent.

[0056] Exemplarily, the grades of the above-mentioned hot stamping steel plates include HC1200 / 1800HS+AS (the corresponding yield strength is 1700Mpa-1800Mpa, and the tensile strength is 1800Mpa-2150Mpa; HC refers to high-strength steel; AS refers to aluminum alloy coating), HC950 / 1300HS+AS (the corresponding yield strength is 950Mpa-1250Mpa, and the tensile strength is 1300Mpa-1700Mpa), HC800 / 1000HS+AS (the corresponding yield strength is 800Mpa-1100Mpa, and the tensile strength is 1000Mpa-1300Mpa) and HC370 / 550HS+AS (the corresponding yield strength is 370Mpa-550Mpa, and the tensile strength is 550Mpa-750Mpa), etc.

[0057] For example, at least a portion of the A-pillar reinforcement section 1 may be made of a hot stamped steel plate with grades HC1200 / 1800HS+AS or HC950 / 1300HS+AS; at least a portion of the B-pillar reinforcement section 2 may be made of a hot stamped steel plate with grades HC950 / 1300HS+AS or HC800 / 1000HS+AS; and at least a portion of the door sill reinforcement section 3 may be made of a hot stamped steel plate with grades HC800 / 1000HS+AS or HC370 / 550HS+AS.

[0058] In some embodiments, the materials corresponding to all the side reinforcements 10 are different. In this way, the collision protection and energy absorption performance of the vehicle side reinforcement structure in the circumferential direction of the entire annular structure 101 are more refined, so that the anti-collision protection performance of the vehicle is better and the safety of the driver and passengers is higher.

[0059] For example, in a specific implementation, for example, the grades of materials corresponding to all side panel reinforcements 10 may be different.

[0060] In some embodiments, reference Figures 1 to 3 As shown, the number of the side panel reinforcements 10 is no more than seven, and the side panel reinforcements 10 are sequentially connected to form an annular structure 101 .

[0061] That is to say, the number of side panel reinforcements 10 is between three and seven. This arrangement, while ensuring fine control over the collision protection and energy absorption performance of the vehicle side panel reinforcement structure in the circumferential direction of the entire annular structure 101, can also, to a certain extent, avoid the situation where an increase in the number of side panel reinforcements 10 leads to an increase in connection cost and a decrease in connection efficiency before the molding of the vehicle side panel reinforcement structure.

[0062] When forming each side wall reinforcement 10, a whole blank is cut according to the shape and size of the corresponding side wall reinforcement 10 to preform the corresponding side wall reinforcement 10. Since the vehicle side wall reinforcement structure is an annular structure 101, by making the number of the side wall reinforcement 10 at most seven, the annular structure 101 is divided into seven sections at most, thereby improving the material utilization rate when forming each side wall reinforcement 10 to a certain extent, reducing the probability of material cutting waste to a certain extent, and helping to reduce manufacturing costs.

[0063] In specific implementation, for example, the annular structure 101 can be cut and merged accordingly according to the structural shape of the annular structure 101 and the strength requirements at different positions of the annular structure 101, so as to reduce the welding cost of the vehicle side panel reinforcement structure and improve the material utilization rate during the production of each side panel reinforcement 10.

[0064] In some embodiments, reference Figures 1 to 3 As shown, the A-pillar reinforcement section 1 includes an A-pillar upper reinforcement section 11 and an A-hinge pillar reinforcement section 12. The A-pillar upper reinforcement section 11 is connected between the B-pillar reinforcement section 2 and the A-hinge pillar reinforcement section 12, and one end of the A-hinge pillar reinforcement section 12 away from the A-pillar upper reinforcement section 11 is connected to the door sill reinforcement section 3. The A-pillar upper reinforcement section 11 is at least used to correspond to the A-pillar of the vehicle.

[0065] In this way, the A-pillar reinforcement section 1 is split into the connected A-pillar upper reinforcement section 11 and the A-hinge column reinforcement section 12. This makes it convenient to assign different materials to the A-pillar upper reinforcement section 11 and the A-hinge column reinforcement section 12 according to the strength requirements at different positions of the A-pillar reinforcement section 1 (for example, the A-pillar upper reinforcement section 11 and the A-hinge column reinforcement section 12 can be assigned different grades of materials), so as to perform more refined control over the collision protection and energy absorption performance of the A-pillar reinforcement section 1, and improve the safety of the vehicle when driving.

[0066] For example, the A-pillar upper reinforcement section 11 and the A-hinge pillar reinforcement section 12 may be connected by laser welding.

[0067] In some embodiments, reference Figure 2 As shown, the A-hinge pillar reinforcement section 12 includes an A-hinge pillar upper reinforcement section 121 and an A-hinge pillar lower reinforcement section 122. The A-hinge pillar upper reinforcement section 121 is connected between the A-hinge pillar upper reinforcement section 11 and the A-hinge pillar lower reinforcement section 122. The end of the A-hinge pillar lower reinforcement section 122 away from the A-hinge pillar upper reinforcement section 11 is connected to the door sill reinforcement section 3.

[0068] This arrangement makes it convenient to assign different materials to the A-hinge column upper reinforcement section 121 and the A-hinge column lower reinforcement section 122 according to the strength requirements at different positions of the A-hinge column reinforcement section 12, so as to achieve refined control over the collision protection and energy absorption performance of the A-hinge column reinforcement section 12, thereby further improving the safety of the vehicle when driving.

[0069] For example, the A-hinge column upper reinforcement section 121 is connected between the A-hinge column upper reinforcement section 11 and the A-hinge column lower reinforcement section 122 by laser welding, and the A-hinge column lower reinforcement section 122 and the door sill reinforcement section 3 are connected by laser welding.

[0070] In some embodiments, reference Figures 1 to 3 As shown, the B-pillar reinforcement section 2 includes a first B-pillar reinforcement section 21 and a second B-pillar reinforcement section 22. The first B-pillar reinforcement section 21 is connected between the rocker reinforcement section 3 and the second B-pillar reinforcement section 22, and one end of the second B-pillar reinforcement section 22 away from the first B-pillar reinforcement section 21 is connected to the A-pillar reinforcement section 1.

[0071] This arrangement makes it easy to assign different materials to the B-pillar first reinforcement section 21 and the B-pillar second reinforcement section 22 according to the strength requirements at different positions of the B-pillar reinforcement section 2, so as to achieve refined control of the collision protection and energy absorption performance of the B-pillar reinforcement section 2, further improving the safety of the vehicle when driving.

[0072] For example, the first B-pillar reinforcement section 21 and the second B-pillar reinforcement section 22 may be connected by laser welding.

[0073] In some embodiments, reference Figure 3 As shown, the second B-pillar reinforcement section 22 includes a B-pillar upper reinforcement section 221 and a B-pillar lower reinforcement section 222. The B-pillar upper reinforcement section 221 is connected between the A-pillar reinforcement section 1 and the B-pillar lower reinforcement section 222, and the end of the B-pillar lower reinforcement section 222 away from the B-pillar upper reinforcement section 221 is connected to the B-pillar first reinforcement section 21.

[0074] This arrangement makes it easy to assign different materials to the B-pillar upper reinforcement section 221 and the B-pillar lower reinforcement section 222 according to the strength requirements at different positions of the B-pillar second reinforcement section 22, so as to achieve refined control over the collision protection and energy absorption performance of the B-pillar second reinforcement section 22, further improving the safety of the vehicle when driving.

[0075] For example, the B-pillar upper reinforcement segment 221 is connected between the A-pillar upper reinforcement segment 11 and the B-pillar lower reinforcement segment 222 of the A-pillar reinforcement segment 1 by laser welding, and the B-pillar lower reinforcement segment 222 is connected to the B-pillar first reinforcement segment 21 by laser welding.

[0076] For example, refer to Figure 1 As shown, when the side reinforcement 10 includes the A-pillar upper reinforcement section 11, the A-hinge pillar reinforcement section 12, the rocker reinforcement section 3, the B-pillar first reinforcement section 21 and the B-pillar second reinforcement section 22 connected in sequence, the number of the side reinforcements 10 is five.

[0077] For example, refer to Figure 1 and Figure 2 As shown, for example, the A-pillar upper reinforcement section 11 and the A-hinge pillar reinforcement section 12 can be formed in one piece, and the number of side reinforcement members 10 is reduced from five to four. For example, the door sill reinforcement section 3 and the B-pillar first reinforcement subsection 21 can be further formed in one piece, and the number of side reinforcement members 10 is reduced from four to three.

[0078] For example, refer to Figures 1 to 3 As shown, when the A-hinge pillar reinforcement section 12 is split into the A-hinge pillar upper reinforcement section 121 and the A-hinge pillar lower reinforcement section 122 , and the B-pillar second reinforcement section 22 is split into the B-pillar upper reinforcement section 221 and the B-pillar lower reinforcement section 222 , the number of the side panel reinforcements 10 is seven.

[0079] In some embodiments, reference Figure 2 As shown, at least one side wall reinforcement 10 is further provided with a reinforcement member 102. Such a configuration can enhance the strength of the corresponding side wall reinforcement 10 to a certain extent, thereby making the strength of the side wall reinforcement structure for the whole vehicle higher and having a better strengthening effect on the side wall strength.

[0080] For example, refer to Figure 2 As shown, for example, the reinforcing member 102 may be connected to the reinforcing section 11 on the A-pillar to further improve the strength of the A-pillar reinforcing section 1 and provide better protection for the driver and passengers.

[0081] In some embodiments, the reinforcement 102 is pre-connected to one side of the side panel reinforcement 10 by welding, and is hot stamped to form a whole with the side panel reinforcement 10 .

[0082] With such an arrangement, the side panel reinforcement 10 and the reinforcement 102 can be welded together first, and then the side panel reinforcement 10 and the reinforcement 102 can be hot stamped once through a corresponding stamping die, so that the side panel reinforcement 10 and the reinforcement 102 form a corresponding three-dimensional structure. This can reduce the number of stamping dies and the number of hot stamping times required for the forming of the side panel reinforcement 10 and the reinforcement 102 to a certain extent, thereby not only reducing the production cost, but also improving the vehicle's body-in-white manufacturing efficiency, thereby improving the vehicle's production efficiency.

[0083] For example, the reinforcement member 102 may be first welded to one side of the corresponding side reinforcement member 10, and then the side reinforcement members 10 are welded together, and finally the final vehicle side reinforcement structure is formed by hot stamping. The reinforcement member 102 may be welded to the corresponding side reinforcement member 10 by spot welding, for example.

[0084] Of course, in another implementation, the reinforcement piece 102 may be first stamped into a three-dimensional structure, and then the preformed structure may be stamped, and finally the stamped reinforcement piece 102 may be welded to the corresponding side reinforcement piece 10 in the preformed structure.

[0085] The present embodiment further provides a side panel assembly, including a side panel and a vehicle side panel reinforcement structure connected to the side panel.
