[0046] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0047] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0048] With the rapid development of the automotive industry and the gradual popularization of electric vehicles, the requirements for vehicle safety and range are becoming increasingly stringent. Against this backdrop, designing a structure that is both safe and lightweight is becoming increasingly important.

[0049] refer to Figure 1As shown, in conventional vehicles, a single reinforcing plate 300 is typically designed in the rear structural area. This reinforcing plate 300 and the inner plate form a large cavity. Due to the large volume of this cavity, insufficient local stiffness often occurs in the center and transition areas of the reinforcing plate 300. This can lead to torsion problems or noise, vibration, and harshness (NVH) issues in the vehicle.

[0050] refer to Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, this application proposes a reinforcing component 10 for connecting a first component 210, a second component 220, and a third component 230. That is, the reinforcing component 10 connects three components of the vehicle simultaneously, and the force between the three components is transmitted through the reinforcing component 10.

[0051] The reinforcing component 10 includes a first connector 110, a second connector 120, and a third connector 130. The first connector 110 is connected to the first component 210, the second connector 120 is connected to the second component 220, and the third connector 130 is connected to the third component 230.

[0052] The first connecting member 110, the second connecting member 120, and the third connecting member 130 are fixed to each other and form a triangle. It should be noted that the fixing of the first connecting member 110, the second connecting member 120, and the third connecting member 130 can be either direct contact and fixing in pairs, or simultaneous fixing to the same component for indirect fixing. For example, the first connecting member 110 and the second connecting member 120 can be simultaneously fixed to the first component 210 for indirect fixing. Whether direct or indirect fixing is used, as long as movement between them is restricted, it falls within the scope of protection of this application.

[0053] Furthermore, the first connector 110, the second connector 120, and the third connector 130 are arranged in a triangle. That is, each connector is connected to the other two connectors at its two ends or near its ends. The triangle can be an equilateral triangle or an irregular triangle; this application does not impose any restrictions. When the triangle is an equilateral triangle, the first connector 110, the second connector 120, and the third connector 130 have the same length and are arranged in a straight line. When the triangle is an irregular triangle, the length, curvature, and even thickness of the first connector 110, the second connector 120, and the third connector 130 can be different; that is, as long as the three connectors can form a triangular shape, it is within the scope of protection of this application.

[0054] Since the first connector 110, the second connector 120, and the third connector 130 form a triangle, and triangles have high stability, they possess excellent rigidity, thus significantly improving the torsional resistance of the vehicle body. Furthermore, because no cavity is formed between the first connector 110, the second connector 120, and the third connector 130, the noise, vibration, and roughness problems caused by cavities can be mitigated to some extent. Simultaneously, compared to the reinforcing plate 300, the structure of the first connector 110, the second connector 120, and the third connector 130 requires less space, is lighter, and has a lower cost. Moreover, the forces between the first component 210, the second component 220, and the third component 230 are directly transmitted through the first connector 110, the second connector 120, and the third connector 130, thus avoiding the problem of insufficient local rigidity often found in the center and transition areas.

[0055] In one embodiment, reference Figure 2 and Figure 3 As shown, the first connector 110, the second connector 120, and the third connector 130 are configured as expansion tubes, and are fixed to each other via the outer walls of the expansion tubes. It should be noted that the first connector 110, the second connector 120, and the third connector 130 can be connected and fixed using either spot welding or bolts. Furthermore, multiple spot welding points and bolt points can be provided, and their positions and numbers can be determined according to the actual situation. In addition, the aforementioned expansion tubes are hot-air expansion tubes, which have better strength than the reinforcing plate 300, thus improving structural stability and the rigidity of this area. Simultaneously, the expansion tubes are designed as pipes, allowing adjacent expansion tubes to be fitted together for easy fixing.

[0056] When the wall thickness of the expansion tubes of the first connector 110, the second connector 120, and the third connector 130 is too small, their stiffness is too low, making them easily crushed during force transmission. Conversely, when the wall thickness of the expansion tubes of the first connector 110, the second connector 120, and the third connector 130 is too large, it increases the cost of the first connector 110, the second connector 120, and the third connector 130, and also increases the weight of the entire vehicle. In this embodiment, the wall thickness of the expansion tubes of the first connector 110, the second connector 120, and the third connector 130 is set to be greater than or equal to 0.4 mm and less than or equal to 3 mm. Within this range, on the one hand, the first connector 110, the second connector 120, and the third connector 130 have sufficient stiffness and will not be crushed during force transmission; on the other hand, the cost of the first connector 110, the second connector 120, and the third connector 130 is within a suitable range and will not significantly increase the vehicle's weight. For example, the wall thickness of the expansion tubes of the first connector 110, the second connector 120, and the third connector 130 can be set to 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, and 3.0mm.

[0057] Furthermore, if the cross-sectional areas of the expansion tubes of the first connector 110, the second connector 120, and the third connector 130 differ too much, it will lead to uneven force transmission among them, resulting in stress concentration. On the other hand, a large difference in cross-sectional areas will make the area irregular in shape, thus making it aesthetically unpleasing.

[0058] In this embodiment, the ratio between the cross-sectional area of ​​the first connector 110 and the cross-sectional area of ​​the second connector 120 is set to be greater than or equal to 1 / 2 and less than or equal to 2. Simultaneously, the ratio between the cross-sectional area of ​​the second connector 120 and the cross-sectional area of ​​the third connector 130 is set to be greater than or equal to 1 / 2 and less than or equal to 2. Furthermore, the ratio between the cross-sectional area of ​​the third connector 130 and the cross-sectional area of ​​the first connector 110 is set to be greater than or equal to 1 / 2 and less than or equal to 2. That is, the ratio of any two of the first connector 110, the second connector 120, and the third connector 130 is not greater than or equal to 1 / 2 and is less than or equal to 2. Within this range, on the one hand, the force transmission among the first connector 110, the second connector 120, and the third connector 130 is uniform, resulting in greater force transmission. On the other hand, the similar shapes of the areas contribute to an aesthetically pleasing appearance. For example, the ratio can be set to 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0.

[0059] In one embodiment, reference Figure 2 and Figure 3 As shown, at least a portion of the first connector 110, the second connector 120, and the third connector 130 are arranged in an arc shape. If the arc of the arc portion is too small, it will cause the first connector 110, the second connector 120, and the third connector 130 to make a sharp turn in the arc, which will make them prone to break at the bend when transmitting force, thereby damaging the vehicle body.

[0060] This application sets the diameter of the circle corresponding to the arcuate portion of the first connector 110, the second connector 120, and the third connector 130 to be greater than or equal to twice the diameter of the first connector 110, the second connector 120, and the third connector 130. Within this range, the first connector 110, the second connector 120, and the third connector 130 can smoothly transition at the arcuate points, thereby preventing them from breaking. For example, the diameter of the circle corresponding to the arcuate portion of the first connector 110, the second connector 120, and the third connector 130 can be set to twice the diameter of the first connector 110, the second connector 120, and the third connector 130. Alternatively, the diameter of the circle corresponding to the arcuate portion of the first connector 110, the second connector 120, and the third connector 130 can be set to three times the diameter of the first connector 110, the second connector 120, and the third connector 130.

[0061] In one embodiment, reference Figure 4 and Figure 5As shown, the first connecting member 110, the second connecting member 120, and the third connecting member 130 are fixed to each other in the following manner: the first component 210 is connected to the second connecting member 120, and the force of the first component 210 is transmitted outward through the first connecting member 110 and the second connecting member 120. That is, the first connecting member 110 and the second connecting member 120 are not fixed to each other, but are directly fixed to the first component 210 to achieve fixation between the first connecting member 110 and the second connecting member 120. With this arrangement, when the first component 210 transmits force to the second component 220, it can directly pass through the first connecting member 110. At the same time, when the first component 210 transmits force to the third component 230, it can directly pass through the second connecting member 120. Therefore, it is not necessary for all the force of the first component 210 to pass through the first connecting member 110, so as to achieve the effect of dispersing pressure.

[0062] Similarly, in this embodiment, reference Figure 4 and Figure 5 As shown, the second component 220 can be connected to the third connector 130, and the force of the second component 220 is transmitted outward through the second connector 120 and the third connector 130. That is, the pressure of the second component 220 can be distributed to the second connector 120 and the third connector 130, thereby avoiding pressure concentration and thus avoiding the problem of insufficient local stiffness.

[0063] Alternatively, the third component 230 can be connected to the first connector 110, and the force of the third component 230 can be transmitted outward through the third connector 130 and the first connector 110. Similarly, the pressure of the third component 230 can be distributed to the third connector 130 and the first connector 110, thereby avoiding the problem of pressure concentration.

[0064] Based on the above configuration, in this embodiment, the first component 210 directly transmits pressure through the first connector 110 and the second connector 120, the second component 220 directly transmits pressure through the second connector 120 and the third connector 130, and the third component 230 directly transmits pressure through the third connector 130 and the first connector 110. That is, the pressure of each component is directly transmitted outward through two connectors. This configuration allows each component connected to the reinforcing assembly 10 to transmit pressure outward through two connectors, thereby improving the durability of the reinforcing assembly 10.

[0065] This application also proposes a vehicle body including side beam reinforcement plates, rear crossbeam reinforcement plates, wheel arch reinforcement plates, and the reinforcement component 10 described in the above embodiments. The side beam reinforcement plates, rear crossbeam reinforcement plates, and wheel arch reinforcement plates are components in the vehicle body structure used to improve vehicle safety and rigidity. The main function of the side beam reinforcement plate is to effectively disperse impact forces during side collisions, reducing intrusion into the passenger compartment and protecting the safety of passengers. It can also increase the lateral rigidity of the vehicle body, improving vehicle handling performance. The rear crossbeam reinforcement plate can improve the rigidity of the rear of the vehicle, enhancing the vehicle's impact resistance during rear-end collisions and reducing the impact on occupants. Furthermore, it helps maintain the structural integrity of the vehicle body, preventing deformation due to rear-end damage. The main purpose of the wheel arch reinforcement plate is to increase the strength of the wheel arch area, preventing wheel arch deformation or breakage during a collision, thereby protecting the tires and other suspension components from damage. In addition, it can improve the overall rigidity of the vehicle, contributing to improved driving stability. The design and installation of these reinforcement plates play a crucial role in improving the overall performance of the vehicle, especially in terms of collision safety.

[0066] The reinforcing components 10 are connected to the side beam reinforcing plate, the rear crossbeam reinforcing plate, and the wheel arch reinforcing plate, respectively. Specifically, the first connecting member 110 is connected to the rear crossbeam reinforcing plate, the second connecting member 120 is connected to the wheel arch reinforcing plate, and the third connecting member 130 is connected to the side beam reinforcing plate.

[0067] refer to Figure 4 and Figure 5 As shown, the rear crossbeam reinforcement plate is the first component 210, the wheel arch reinforcement plate is the second component 220, and the side beam reinforcement plate is the third component 230. This area is subjected to the combined force of the side beam, rear crossbeam, and wheel arch components, so local stiffness deficiency often occurs in this area, leading to vehicle torsion.

[0068] The first connector 110, the second connector 120, and the third connector 130 of this application form a triangle. Triangles have high stability and therefore excellent rigidity, which significantly improves the torsional resistance of the vehicle body. Furthermore, the forces between the side beam reinforcement plate, the rear cross beam reinforcement plate, and the wheel arch reinforcement plate are directly transmitted through the first connector 110, the second connector 120, and the third connector 130, thus preventing the frequent occurrence of insufficient local rigidity in the center and transition areas.

[0069] In one embodiment, reference Figure 6 , Figure 7 , Figure 8 as well as Figure 9As shown, the vehicle body also includes a tailgate portion 400 and a strut 500, both of which are connected to the second connector 120. When the tailgate portion 400 is opened, the strut 500, the tailgate portion 400, and the second connector 120 form a triangular arrangement.

[0070] Based on the above configuration, both the tailgate section 400 and the support rod 500 are mounted on the second connector 120, forming a triangular arrangement. This triangular arrangement improves the stability of the tailgate section 400 and the support rod 500, and because they are connected to the same connector, they are less prone to deformation.

[0071] Furthermore, at this time, the first connector 110, the second connector 120, and the third connector 130 are also arranged in a triangle, that is, two triangles are formed here, which can greatly improve the torsional stiffness and modal characteristics at the tailgate 400.

[0072] In one embodiment, the second connector 120 is further provided with a through hole that penetrates one side wall of the second connector 120, and the tailgate portion 400 and the support rod 500 are connected in the through hole.

[0073] The through hole extends through one side wall of the second connector 120, meaning that the entire second connector 120 is not completely destroyed, thus not significantly affecting its overall performance. This allows the second connector 120 to connect the tailgate 400 and the strut 500 while simultaneously transmitting force normally.

[0074] Furthermore, it should be noted that the vehicle body also includes multiple connection points. Whenever reinforcement is required at these locations, the reinforcing component 10 proposed in this application can be moved to improve the torsional resistance of the vehicle body and solve the problem of insufficient local stiffness that often occurs at the center and transition areas of the connection points.

[0075] This application also proposes a vehicle comprising the body described in the above embodiments. Because the vehicle possesses the aforementioned body, it also possesses the functions and advantages of that body. The vehicle can be a sedan, truck, bus, etc.

[0076] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
