[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to welding, detachable connection, or integral integration; they can refer to mechanical connection or electrical connection; they can refer to direct connection or indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] like Figure 1 As shown, this utility model provides a vehicle body side reinforcement structure, including a side reinforcement body, the side reinforcement body including a first annular portion 10 and a second annular portion 20, the first annular portion 10 and the second annular portion 20 are connected to each other, at least one of the first annular portion 10 and the second annular portion 20 has a thickness different from the thickness of the remaining portions, and the side reinforcement body is a welded plate thermoformed part.

[0032] The main body of the side panel reinforcement is a hot-formed welded plate component. Compared with related technologies, this saves vehicle manufacturing time and improves production efficiency. Furthermore, the reduced number of molds required in the early stages of side panel manufacturing lowers development costs and also increases production efficiency. In addition, at least a portion of the thickness of the first annular portion 10 and the second annular portion 20 differs from the thickness of the remaining portions. This allows the overall rigidity of the side panel reinforcement structure to be limited according to requirements, thus improving the lean design of the side panel reinforcement structure and optimizing its performance based on performance needs. The first annular portion 10 and the second annular portion 20 also prevent the side panel reinforcement structure from deforming during transportation, thereby improving vehicle safety.

[0033] The side reinforcement body has a first annular part 10 and a second annular part 20. In the event of a frontal collision, side collision and rear collision, the first annular part 10 and the second annular part 20 are the key protection areas for the first and second row occupants of the vehicle, respectively. Therefore, its structure must be strong enough to protect the first and second row occupants and prevent them from being injured.

[0034] Specifically, the side reinforcement body includes a first reinforcing column 1, a second reinforcing column 2, a third reinforcing column 3, a fourth reinforcing column 4, a fifth reinforcing column 5, and a sixth reinforcing column 6, wherein the first reinforcing column 1, the second reinforcing column 2, the third reinforcing column 3, and the fourth reinforcing column 4 form a first annular portion 10, and the third reinforcing column 3, the fourth reinforcing column 4, the fifth reinforcing column 5, and the sixth reinforcing column 6 form a second annular portion 20.

[0035] The first annular portion 10 and the second annular portion 20 are connected by a shared third reinforcing post 3 and a fourth reinforcing post 4.

[0036] Furthermore, in the first reinforcing column 1, the second reinforcing column 2, the third reinforcing column 3, the fourth reinforcing column 4, the fifth reinforcing column 5, and the sixth reinforcing column 6, the thickness of at least one part of each reinforcing column is different from the thickness of the rest. That is, in the above-mentioned reinforcing columns, the thickness of each reinforcing column is completely different, or it may be partially the same and the other part different.

[0037] Specifically, the first reinforcing column 1 is located above the second reinforcing column 2, the third reinforcing column 3 is located above the fourth reinforcing column 4, and the fifth reinforcing column 5 is located above the sixth reinforcing column 6.

[0038] Through the above technical solution, the first reinforcing pillar 1, the second reinforcing pillar 2, the third reinforcing pillar 3, the fourth reinforcing pillar 4, the fifth reinforcing pillar 5 and the sixth reinforcing pillar 6 can be obtained simultaneously, improving manufacturing efficiency. Furthermore, since the thickness of at least one part of each reinforcing pillar is different from the thickness of the rest, the leanness of the vehicle side reinforcement structure can be improved, and the optimal performance can be achieved according to the performance requirements of the vehicle side reinforcement structure.

[0039] In some embodiments, adjacent reinforcing columns of the first reinforcing column 1, the second reinforcing column 2, the third reinforcing column 3, the fourth reinforcing column 4, the fifth reinforcing column 5, and the sixth reinforcing column 6 are laser-welded together.

[0040] Specifically, multiple reinforcing pillars are laser-welded together to form a side panel reinforcement structure for the vehicle body. Laser welding can complete the welding process in a short time, with a large weld depth and minimal deformation. Laser welding can achieve high-quality welds and precise control, making it suitable for welding complex structures. Furthermore, laser welding is a non-contact welding process, avoiding mechanical stress damage, and the weld strength can reach over 95% of the base material. Laser welding results in a strong connection between multiple blanks, thus this type of side panel reinforcement structure makes vehicles using it less likely to separate due to the enormous impact force in a frontal collision, further improving vehicle safety.

[0041] By laser welding each reinforcing column and then thermoforming it as a whole, the weight of the superimposed weld edge thickness can be saved, reducing the overall vehicle weight and achieving the goal of lightweighting.

[0042] In some embodiments, at least two of the first reinforcing column 1, the second reinforcing column 2, the third reinforcing column 3, the fourth reinforcing column 4, the fifth reinforcing column 5, and the sixth reinforcing column 6 are hot-formed steel plates of different grades.

[0043] For example, different grades of hot-formed steel plates can be selected for different reinforcing pillars. Alternatively, the grades of hot-formed steel plates selected for different blanks can not be exactly the same. That is, the first reinforcing pillar 1, the second reinforcing pillar 2, the third reinforcing pillar 3, the fourth reinforcing pillar 4, the fifth reinforcing pillar 5, and the sixth reinforcing pillar 6 can use more than two grades of hot-formed steel plates. This arrangement ensures that the strength of the blanks in different locations meets the requirements, achieving different tensile strengths for each reinforcing pillar, and correspondingly increasing the strength of the reinforcing pillars. This provides overall protection for the vehicle body under frontal, side, and rear collision conditions, and allows for precise control and absorption of collision energy.

[0044] Of course, in some other embodiments, the reinforcing column can be made of the same grade of hot-formed steel sheet.

[0045] It should be noted that the grade and thickness of each reinforcing pillar in the vehicle body side reinforcement structure can be flexibly adjusted according to performance requirements.

[0046] In some embodiments, the side reinforcement body further includes a third annular portion 30, which is connected to the first annular portion 10.

[0047] The main body of the side panel reinforcement is a hot-formed welded plate, which saves vehicle manufacturing time compared to related technologies, thereby improving production efficiency. The reduced number of molds required in the early stages of side panel manufacturing lowers development costs and also increases production efficiency. Furthermore, at least one portion of the first annular portion 10 and the third annular portion 30 has a thickness different from the remaining portions. This allows the stiffness of the side panel reinforcement structure to be limited by thickness according to requirements, improving the leanness of the side panel reinforcement structure and optimizing its performance according to the needs. The first annular portion 10 and the second annular portion 20 also prevent the side panel reinforcement structure from deforming during transportation, thus improving vehicle safety.

[0048] In some embodiments, the side reinforcement body further includes a seventh reinforcing post 7 and an eighth reinforcing post 8, and the first reinforcing post 1, the second reinforcing post 2, the seventh reinforcing post 7 and the eighth reinforcing post 8 form a third annular portion 30.

[0049] The first annular portion 10 and the third annular portion 30 share the first reinforcing post 1 and the second reinforcing post 2, which enables the connection between the first annular portion 10 and the third annular portion 30.

[0050] In some embodiments, the first annular portion 10 and / or the second annular portion 20 are variable cross-sectional thickness structural members.

[0051] This design can improve the strength of the corresponding annular part, and achieve overall protection of the vehicle body under conditions such as frontal collision, side collision, and rear collision. The stiffness of the vehicle body side reinforcement structure is limited by the thickness according to the requirements, which can improve the leanness of the vehicle body side reinforcement structure and achieve the optimal performance according to the performance requirements of the vehicle body side reinforcement structure.

[0052] Understandably, the third annular portion 30 is also a variable cross-section thickness structural component. This design allows for further thickness limitation of the body side reinforcement structure's stiffness according to requirements, thus improving the leanness of the body side reinforcement structure and achieving optimal performance based on its requirements. Furthermore, the third annular portion 30 can meet the strength and manufacturing requirements of different vehicle models.

[0053] In some embodiments, multiple blanks are welded together to form a vehicle side reinforcement structure blank 100, and the vehicle side reinforcement structure blank 100 is integrally thermoformed to form a vehicle side reinforcement structure.

[0054] like Figure 2 and Figure 3As shown, exemplarily, the first reinforcing post 1, the second reinforcing post 2, the third reinforcing post 3, the fourth reinforcing post 4, the fifth reinforcing post 5, and the sixth reinforcing post 6 are respectively the first blank 101, the second blank 102, the third blank 103, the fourth blank 104, the fifth blank 105, and the sixth blank 106 before thermoforming. The first blank 101, the second blank 102, the third blank 103, the fourth blank 104, the fifth blank 105, and the sixth blank 106 are laser welded to form a vehicle side wall reinforcing structure blank 100. After obtaining the vehicle side wall reinforcing structure blank 100 through laser welding, the vehicle side wall reinforcing structure is obtained by thermoforming through a mold.

[0055] pass Figure 2 The body side reinforcement structure obtained from the provided body side reinforcement structure blank 100 has B-pillar, C-pillar and D-pillar.

[0056] pass Figure 3 The side body reinforcement structure obtained from the provided blank 100 has an A-pillar, a B-pillar, and a C-pillar.

[0057] like Figure 4 As shown, exemplarily, the first reinforcing column 1, the second reinforcing column 2, the third reinforcing column 3, the fourth reinforcing column 4, the fifth reinforcing column 5, the sixth reinforcing column 6, the seventh reinforcing column 7, and the eighth reinforcing column 8 are first laser welded before thermoforming. Before thermoforming, the first reinforcing column 1, the second reinforcing column 2, the third reinforcing column 3, the fourth reinforcing column 4, the fifth reinforcing column 5, the sixth reinforcing column 6, the seventh reinforcing column 7, and the eighth reinforcing column 8 are respectively the first blank 101, the second blank 102, the third blank 103, the fourth blank 104, and the fifth blank 105. Material 104, fifth blank 105, sixth blank 106, seventh blank 107 and eighth blank 108, first blank 101, second blank 102, third blank 103, fourth blank 104, fifth blank 105, sixth blank 106, seventh blank 107 and eighth blank 108 are laser welded to form a vehicle side wall reinforcement structure blank 100. After obtaining the vehicle side wall reinforcement structure blank 100 by laser welding, the vehicle side wall reinforcement structure is obtained by thermoforming with a mold.

[0058] pass Figure 4 The side body reinforcement structure blank 100 provided in the middle has A-pillar, B-pillar, C-pillar and D-pillar.

[0059] The vehicle body side reinforcement structure provided by the above solution has a first annular portion 10, a second annular portion 20 and a third annular portion 30. In the event of a frontal collision, a side collision and a rear collision, the first annular portion 10, the second annular portion 20 and the third annular portion 30 are the key protection areas for the occupants of the first, second and third rows of the vehicle, respectively. Therefore, its structure must be strong enough to protect the occupants of the first, second and third rows and prevent them from being injured.

[0060] The body side reinforcement structure is obtained by welding the above-mentioned blanks and then heat forming them. Different blanks correspond to different reinforcement pillars, so there is no need to develop additional molds, which reduces development and production costs. Compared with related technologies that involve stamping first and then welding, it improves manufacturing efficiency.

[0061] During the manufacturing process, by adjusting the structure of the stamping die and the cooling water circuit, the strength of the task component can be reduced after the body side reinforcement structure blank 100 is hot-formed, with the minimum strength reaching 550MPa, in order to meet different performance requirements.

[0062] In some embodiments, the first annular portion 10 and / or the second annular portion 20 are provided with patch plates.

[0063] The patch plate can reinforce the aforementioned reinforcing columns, thereby improving their strength and preventing weak areas from appearing after stamping, thus improving the strength of the local structure.

[0064] It is understandable that a patch plate is provided on any one of the first billet 101, the second billet 102, the third billet 103, the fourth billet 104, the fifth billet 105, the sixth billet 106, the seventh billet 107, and the eighth billet 108. The patch plate is specifically located in the weak area of ​​any one of the first billet 101, the second billet 102, the third billet 103, the fourth billet 104, the fifth billet 105, the sixth billet 106, the seventh billet 107, and the eighth billet 108.

[0066] Because it includes a side panel reinforcement structure, the main body of which comprises a first annular portion 10 and a second annular portion 20, and the main body of which is a welded sheet thermoformed part, it saves vehicle manufacturing time compared to related technologies, thereby improving production efficiency. Furthermore, the reduced number of molds required in the early stages of side panel manufacturing lowers development costs and also improves production efficiency. In addition, at least one portion of the first annular portion 10 and the second annular portion 20 has a thickness different from the remaining portions, allowing the stiffness of the side panel reinforcement structure to be limited by thickness according to requirements. This improves the lean design of the side panel reinforcement structure, optimizing its performance according to the requirements. The first annular portion 10 and the second annular portion 20 also prevent the side panel reinforcement structure from deforming during transportation, thereby improving vehicle safety.

[0067] This utility model also provides a vehicle, including the body provided by this utility model.

[0068] Because the vehicle body includes the aforementioned structure, it comprises a side reinforcement body, which includes a first annular portion 10 and a second annular portion 20. The side reinforcement body is a thermoformed part made of welded sheet metal. Compared to related technologies, this saves overall vehicle manufacturing time and improves production efficiency. Furthermore, the reduced number of molds required for the side body during early manufacturing reduces development costs and also improves production efficiency. In addition, at least a portion of the first annular portion 10 and the second annular portion 20 has a thickness different from the remaining portions.
