[0002] With the development of vehicles, the safety requirements for vehicles are getting higher and higher, and various collision regulations and evaluation requirements are also becoming more and more stringent. Among them, the 25% offset frontal collision has relatively strict requirements for the vehicle body structure. In the vehicle body structure, the structure of the outer plate of the front side wall connecting plate has a great influence on the offset collision.
[0003] In the related art, in order to improve the structural strength of the vehicle body, generally, a reinforcing plate is welded inside the outer plate of the front side wall connecting plate near the A-pillar area at the rear end. However, this design requires additional welding processes and also increases the labor and part costs. Utility Model Content
[0004] This application provides a side wall connecting plate, a vehicle body assembly, and a vehicle to solve the technical problem of poor structural strength of the side wall connecting plate in the related art.
[0005] On the one hand, this application provides a side wall connecting plate, including a side wall connecting plate body. The side wall connecting plate body includes at least two connecting segments arranged in sequence, and the thicknesses of the connecting segments are different.

[0007] Wherein, the connecting segment is an equal-thickness connecting segment, the thicknesses of at least two connecting segments increase in sequence along the length direction of the side wall connecting plate body, and the thickness of the transition segment is between the thicknesses of two adjacent connecting segments.
[0008] In a possible implementation manner, among two adjacent connecting segments, the thickness of the transition segment gradually increases in the direction from the connecting segment with a small thickness to the connecting segment with a large thickness.
[0009] In a possible implementation manner, there is a thickness difference between two adjacent connecting segments, and the transition length of the transition segment connecting the two connecting segments is 80 - 120 times the thickness difference.
[0010] In a possible implementation manner, the transition length of the transition segment is 100 times the thickness difference, and the thickness difference is 0.2 - 0.5 mm.
[0011] In a possible implementation manner, the extension length of the connecting segment along the vehicle body direction is not less than 50 mm.
[0012] In a possible implementation, the side wall connecting plate body is an integrally stamped plate.
[0013] In a possible implementation, among the two connecting segments at both ends of the side wall connecting plate body, a first lapping portion is formed on one of them, and a second lapping portion is formed on the other; the thickness of the connecting segment with the first lapping portion is greater than the thickness of the connecting segment with the second lapping portion;
[0014] wherein, the first lapping portion is used for connecting with the A-pillar of the vehicle, and the second lapping portion is used for connecting with the front wheelhouse side beam of the vehicle.

[0029] Through the above - mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments
[0030] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0031] As described in the background art, in the related art, in order to improve the structural strength of the vehicle body, a reinforcing plate is generally welded at the inner position near the A - pillar area at the rear end of the outer plate of the front - side - wall connecting plate. However, this design requires additional welding processes and also increases the labor and part costs.
[0032] Based on the above - mentioned related description, the side - wall connecting plate provided in the embodiments of the present application includes a side - wall connecting - plate body. The side - wall connecting - plate body includes at least two connecting segments arranged in sequence, and the thicknesses of the connecting segments are different. Thus, by adjusting the thickness of the plate of the side - wall connecting - plate body, after the vehicle assembles the side - wall connecting plate, the collision energy can pass through the connecting segments with small thickness and then the connecting segments with large thickness in sequence, thereby optimizing the force - transmission path of the side - wall connecting plate during frontal collision and offset collision, enhancing the anti - deformation ability and overall structural strength of the side - wall connecting plate, being conducive to the side - wall connecting plate absorbing and dispersing the collision energy, and improving the overall collision safety of the vehicle body.
[0033] The following describes the side - wall connecting plate of the embodiments of the present application with reference to the drawings.
[0034] As Figure 1 and Figure 2 shown, the side - wall connecting plate of the embodiments of the present application includes a side - wall connecting - plate body 100. The side - wall connecting - plate body 100 includes at least two connecting segments 101 arranged in sequence, and the thicknesses of the connecting segments 101 are different.
[0035] In the related art, the sheet thickness of the side wall connecting plate is uniform. By designing a welding reinforcement plate or arranging a reinforcing rib on the side wall connecting plate, etc., the structural strength of the side wall connecting plate on the vehicle body is enhanced, so that the collision energy can be dispersed and absorbed. Compared with the related art, designing to change the thickness of the side wall connecting plate can, on the one hand, reduce the design difficulty on the premise of ensuring the overall structural strength without a large-scale modification of the structure of the side wall connecting plate, and on the other hand, the use of a reinforcement plate can be eliminated by using the thickness change, thereby reducing the number of installation and use of the reinforcement plate parts, simplifying the assembly process, and improving the production efficiency.
[0036] It should be noted that in the embodiments of the present application, the orientation words such as "front" and "rear" mentioned are described with reference to the vehicle body direction of the vehicle. When the side wall connecting plate is assembled on the vehicle frame, it is connected to the corresponding side wall component to form a vehicle body assembly. Here, by way of example, the side wall connecting plate refers to the outer plate of the front side wall connecting plate. The following will be described by taking the outer plate of the front side wall connecting plate as an example.
[0037] As Figure 2 shown, in some embodiments, the side wall connecting plate body 100 further includes at least one transition section 102, and the transition section 102 is located between two adjacent connection sections 101; wherein, the connection section 101 is an equal-thickness connection section 101, and the thickness of each connection section 101 increases sequentially along the length direction of the side wall connecting plate body 100, and the thickness of the transition section 102 is between the thicknesses of two adjacent connection sections 101.
[0038] Here, by way of example, the length direction of the side wall connecting plate body 100 is parallel to the vehicle body direction. After the side wall connecting plate is assembled, the thickness of each connection section 101 increases sequentially backward along the vehicle body direction.
[0039] Specifically, the side wall component generally has structures such as an A-pillar and a front wheel arch side beam. When a vehicle collides, especially when a offset collision occurs, part of the collision energy will be transmitted along the front wheel arch side beam in the side wall component to the A-pillar, and then transmitted to the roof side beam above the vehicle and the sill beam below the vehicle through the A-pillar respectively to complete the transmission and decomposition of the collision energy.
[0040] In the above description, by way of example, along the vehicle body direction of the vehicle, the side wall connecting plate is connected to the front wheel arch side beam, and the rear end of the side wall connecting plate is connected to the side wall outer plate of the A-pillar. When the vehicle undergoes a 25% offset collision, the impact collision energy received by the front wheel arch side beam is transmitted to the A-pillar through the side wall connecting plate. During this process, since the side wall connecting plate is divided into multiple connection sections 101 with different thicknesses, and the thickness of each connection section 101 increases sequentially backward along the vehicle body direction, as the thickness of the side wall connecting plate gradually increases, the collapse deformation ability of the side wall connecting plate itself gradually weakens from the front end to the rear end, and the collision energy is gradually weakened and transmitted backward along the vehicle body direction to the A-pillar, so that the impact collision energy received by the A-pillar can be reduced as much as possible.
[0041] In the above embodiments, the transition section 102 transitions the connection section 101 with a small thickness to the connection section 101 with a large thickness. The setting of the transition section 102 can prevent stress concentration at the position of sudden thickness change between the two connection sections 101, and avoid fatigue or fracture of the side wall connecting plate at the position of sudden thickness change. In addition, during subsequent electrophoretic coating or painting treatment of the white body, the transition section 102 can make the spraying of the side wall connecting plate more uniform, and prevent the problem of reduced anti-corrosion performance caused by uneven coating at the position of sudden thickness change of the connection section 101.
[0042] In the embodiments of the present application, each connection section 101 is an equal-thickness connection section 101, which means that the thickness of any area on the connection section 101 is the same, and the thicknesses of the respective connection sections 101 are different. For example, along the length direction of the side wall connecting plate body 100, the thicknesses of the connection sections 101 are 0.8 mm, 1.2 mm, and 1.6 mm in sequence.
[0043] Further, in two adjacent connection sections 101, the thickness of the transition section 102 gradually increases in the direction from the connection section 101 with a small thickness to the connection section 101 with a large thickness.
[0044] Since the thickness of the side wall connecting plate itself is relatively thin, generally 0.8 - 2 mm, the actual thickness change of the transition section 102 is not obvious. The setting of gradually increasing the thickness of the transition section 102 can facilitate the production and forming of the side wall connecting plate and simplify the stamping preparation process. Here, the setting of gradually increasing the thickness of the transition section 102 means that the transition section 102 is an unequal-thickness plate.
[0045] In some embodiments, there is a thickness difference between two adjacent connection sections 101, and the transition length of the transition section 102 connecting the two connection sections 101 is 80 - 120 times the thickness difference.
[0046] In the above embodiments, the transition length of the transition section 102 connecting the two connection sections 101 refers to the across length along the vehicle body direction where the transition section 102 transitions to the two adjacent connection sections 101.
[0047] The longer the transition length of the transition section 102, the more uniform the thickness change between two adjacent connection sections 101, and the less likely it is to have a stress concentration problem. However, an overly long transition section 102 also increases the process difficulty. Therefore, the extension length of the transition section 102 between the two connection sections 101 is 80 - 120 times the thickness difference between the two connection sections 101, which can make the transition section 102 transition to the next connection section 101 as uniformly as possible on the premise of meeting the preparation process, ensuring uniform stress distribution of the side wall connecting plate; at the same time, this setting can also reduce the overall weight of the side wall connecting plate on the premise of ensuring structural strength, realizing the lightweight design of the vehicle.
[0048] Exemplarily, the transition length of the transition section 102 connecting the two connecting sections 101 is 80 times, 100 times or 120 times the thickness difference. Preferably, the transition length of the transition section 102 connecting the two connecting sections 101 is 100 times the thickness difference. This setting can ensure a smooth transition of the transition section 102 to the two connecting sections 101.
[0049] In some embodiments, the transition length of the transition section 102 is 100 times the thickness difference, and the thickness difference is 0.2 - 0.5 mm.
[0050] Exemplarily, the thicknesses corresponding to two adjacent connecting sections 101 are 1 mm and 1.2 mm respectively. The thickness difference between the two connecting sections 101 is 0.2 mm, and the transition length of the transition section 102 is 100 times the thickness difference, that is, the extension length of the transition section 102 is 20 mm, so as to ensure that the connecting section 101 with a thickness of 1 mm transitions to the connecting section 101 with a thickness of 1.2 mm through the transition section 102.
[0051] In some embodiments, as Figure 2 shown, the side wall connecting plate is divided into connecting sections 101 with three different plate thicknesses. Among the three connecting sections 101, two adjacent connecting sections 101 are connected by a transition section 102. As an alternative embodiment, the side wall connecting plate may also have other numbers of connecting sections 101. For example, four or five connecting sections 101 are provided. The more the number of divided connecting sections 101, the more complex the stamping process of the side wall connecting plate, but the better the effect of absorbing and buffering collision energy.
[0052] Exemplarily, the extension length of the connecting section 101 along the vehicle body direction is not less than 50 mm. This extension length is also the connection length of the connecting section 101. When the extension length of the connecting section 101 is too small, it may cause uneven stress distribution between the transition section 102 and the connecting section 101, affecting the overall structural strength of the side wall connecting plate. When the transition length of the transition section 102 is too small, it may cause a sudden change in thickness at the connection position between the two connecting sections 101, resulting in stress concentration. When the transition length of the transition section 102 is too large, it will increase the difficulty of the preparation process and is also not conducive to the connecting section 101 absorbing and decomposing collision energy. Therefore, setting the lengths of the transition section 102 and the connecting section 101 within a reasonable range can effectively ensure the structural strength of the side wall connecting plate.
[0053] It should be noted that in the embodiments of the present application, the side wall connecting plate is an integrally stamped plate. The side wall connecting plate is usually made of materials such as high-strength steel, aluminum alloy, and engineering plastic composite materials. When the side wall connecting plate is made of a metal sheet, a press and a mold are used to press the steel plate into the required shape. Here, a cold pressing process is generally used to prepare the side wall connecting plate.
[0054] In some embodiments, among the two connecting segments 101 at both ends of the side wall connecting plate body 100, a first overlapping portion 103 is formed on one, and a second overlapping portion 104 is formed on the other. The thickness of the connecting segment 101 with the first overlapping portion 103 is greater than the thickness of the connecting segment 101 with the second overlapping portion 104;
[0055] Among them, the first overlapping portion 103 is used to connect with the A-pillar of the vehicle, and the second overlapping portion 104 is used to connect with the front wheel arch side beam of the vehicle.
[0056] In the above embodiments, between the first overlapping portion 103 and the A-pillar, and between the second overlapping portion 104 and the front wheel arch side beam, they can be connected by spot welding or by commonly inserted fasteners. Optionally, the fasteners are bolts, screws, buckles or rivets.
[0057] It should be noted that in the embodiments of the present application, in addition to the above structures, the side wall connecting plate should also have other related structures to ensure normal connection effects. This part of the structure can be set with reference to the outer plate of the front side wall connecting plate in the related art. The embodiments of the present application do not make absolute limitations on this. Exemplarily, the side wall connecting plate is provided with a flange for connecting with the inner side wall connecting plate 200, as well as a maintenance port, a positioning boss, etc.
[0058] The embodiments of the present application also provide a vehicle body assembly, as Figure 3 shown, including the side wall connecting plate provided in any one of the above embodiments, and further including an inner side wall connecting plate 200. The side wall connecting plate body 100 of the side wall connecting plate and the inner side wall connecting plate 200 are connected to form a closed cavity.
[0059] Here, between the side wall connecting plate body 100 and the inner side wall connecting plate 200, they can be connected by spot welding or by commonly inserted fasteners. Optionally, the fasteners are bolts, screws, buckles or rivets.
