[0031] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of an embodiment of the vehicle provided in this application. Figure 2 yes Figure 1 Exploded view of the subframe and connecting components before assembly. This application provides a vehicle 100, which includes a subframe 1 and a connecting assembly 2. The connecting assembly 2 includes a support connector 23, a side-mounted connecting beam 22, and a first support reinforcement 21, the first support reinforcement 21 being fixedly connected to the subframe 1. Specifically, the support connector 23 is provided with a first through groove 231 extending along a first direction D1. The first support reinforcement 21 is also connected to a first end of the support connector 23 and extends along a direction opposite to the first through groove 231. The side-mounted connecting beam 22 is provided along a second direction D2 and has a first cavity 221 along the second direction D2. The first end of the side-mounted connecting beam 22 is connected to the support connector 23 and the first support reinforcement 21 respectively. The side-mounted connecting beam 22 covers the first through groove 231 to form a second cavity 232. The side-mounted connecting beam 22, the support connector 23, and the first support reinforcement 21 together form a third cavity 222 communicating with the second cavity 232. The first direction D1 and the second direction D2 intersect. In this embodiment of the application, the vehicle 100 has a connecting component 2 at the mounting point of the subframe 1, and the components of the connecting component 2 form a first cavity 221, a second cavity 232 and a third cavity 222. This simplifies the structure, reduces weight, and absorbs and mitigates external forces through the cavity structure, thereby improving the strength of the mounting point of the subframe 1, and thus improving the load-bearing capacity and strength of the subframe 1. This improves the collision capability of the entire vehicle and achieves the effect of cost reduction and efficiency improvement.

[0032] Please continue to combine Figure 3 and Figure 4, Figure 3 is Figure 1 a schematic structural view of the perspective looking down after the subframe and the connection component are assembled in Figure 4 is Figure 3 a schematic structural view of the A-A cross-section in . Specifically, the second direction D2 can be parallel to the direction from the head to the tail of the vehicle 100, and the first direction D1 can be perpendicular to the second direction D2. The subframe 1 can be a frame structure in a quadrilateral shape, and its four vertices are mounting points for mounting the connection component 2. The first support reinforcement 21 can include a box structure with an overall cross-section presenting an "L" shape and having an opening. The support connection member 23 can include a structure in a "ji" shape from bottom to top in the overall cross-section, and the first through groove 231 is located in the groove of the "ji" shape. Along the first direction D1, the support connection member 23 includes an opposite first end and second end, and its first end forms a closed connection with the first support reinforcement 21. The first cavity 221 and the second cavity 232 are arranged along the third direction D3, and the first cavity 221, the second cavity 232, and the third cavity 222 are all arranged along the first direction D1 and are in a stepped cavity design corresponding up and down. Through the design of the staggered cavities, the three cavities can support each other, thereby improving the structural strength and collision performance of the subframe 1. It should be noted that the third direction D3 is the direction perpendicular to the plane formed by the first direction D1 and the second direction D2.

[0033] Furthermore, during use, as Figure 4 shown, the vehicle 100 of the present application will inevitably generate vibrations. The vibrations are transmitted through the subframe 1 and during the transmission process, will force the subframe 1 to shake along the first direction D1. Due to the presence of the connection component 2, when the subframe 1 shakes along the first direction D1, it can strengthen the mounting points of the subframe 1, absorb and relieve the force and energy generated by the vibration of the mounting points, thereby improving the stiffness and strength of the mounting points of the subframe 1, and further improving the strength of the subframe 1, and enhancing the collision performance, stability and reliability of the vehicle 100.

[0034] Since the first cavity 221, the second cavity 232, and the third cavity 222 are all cavity structures, the overall design structure of the connection component 2 is simple and light in weight. In addition to absorbing and relieving the vibrations generated by the vehicle 100, it can also achieve the effect of reducing costs and increasing efficiency.

[0035] Furthermore, the first cavity 221 presents an arc shape as a whole along the second direction D2, that is, an arc cavity that penetrates up and down. The overall arc-shaped cavity structure design is conducive to improving the bearing capacity and strengthening the overall frame structure, so that the energy decays during the arc-shaped transmission process.

[0036] Please continue to combine Figure 5 , Figure 5 is Figure 3A structural schematic diagram of the BB cross section. In one embodiment of this application, the connecting component 2 further includes a first reinforcing member 24, which is disposed within the first cavity 221; wherein, the first reinforcing member 24 includes at least one recess 241, and the recess 241 together with the inner wall of the first cavity 221 forms a fourth cavity 243.

[0037] Specifically, the first reinforcing member 24 includes a plate 242 and a recess 241. The plate 242 can be welded and fixed to the inner wall of the first cavity 221 to improve the structural strength of the side connecting beam 22. The first reinforcing member 24 has a U-shaped cross-section for the recess 241, with the opening of the U-shape facing the inner wall of the first cavity 221, so that the recess 241 and the inner wall of the first cavity 221 together form a fourth cavity 243. By designing the fourth cavity 243 to absorb and mitigate the external forces generated by vibration, the structural strength of the entire frame can be improved on the one hand; on the other hand, the collision performance of the subframe 1 and even the vehicle 100 can be improved.

[0038] Furthermore, the recess 241 may include an arc-shaped support surface. By designing the arc-shaped support surface, the first reinforcing member 24 can be supported in an arc shape, and the energy it receives can also be transferred in an arc shape, thereby improving the ability to absorb and mitigate external forces and increasing the structural strength.

[0039] In one embodiment of this application, combined with Figure 2 , Figure 4 and Figure 5 As shown, the cabin side connecting beam 22 includes a first beam 223 and a second beam 224. Both the first beam 223 and the second beam 224 are provided with open through slots 226. The open through slots 226 are connected to each other to form a first cavity 221. The first reinforcing member 24 abuts against the inner wall of any open through slot 226. The recess 241 and the inner wall of any open through slot 226 together form a fourth cavity 243.

[0040] Specifically, both the first beam 223 and the second beam 224 are provided with open through slots 226, which can be connected to each other to form a first cavity 221. The first reinforcing member 24 abuts against the inner wall of the open through slot 226, and the structural strength of the open through slot 226 can be improved by welding, gluing or other methods. Furthermore, the recess 241 can also form a fourth cavity 243 together with the inner wall of the open through slot 226.

[0041] Please continue to combine Figure 6 and Figure 7 , Figure 6 yes Figure 3 Schematic diagram of the CC section. Figure 7 yes Figure 3A structural schematic diagram of the DD cross section. In one embodiment of this application, the second end of the cabin side connecting beam 22 is fixedly connected to the subframe 1; the connecting assembly 2 further includes a second support reinforcement 25, which is fixedly connected to the subframe 1; wherein, the second support reinforcement 25 is also connected to the second end of the cabin side connecting beam 22 and extends in a direction opposite to the second end of the cabin side connecting beam 22; the cabin side connecting beam 22 and the second support reinforcement 25 together form a fifth cavity 225.

[0042] Specifically, unlike the first end of the side-mounted connecting beam 22, the second end of the side-mounted connecting beam 22 is directly connected and fixed to the subframe 1, which simplifies the structure and reduces costs.

[0043] Furthermore, the fifth cavity 225 can be rectangular in shape, that is, a rectangular cavity that runs vertically through the body, and covers the mounting point of the entire subframe 1 and the entire second support reinforcement 25; the overall rectangular cavity structure design is conducive to improving the load-bearing capacity and strengthening the overall frame structure, so that energy is resisted and supported during the transmission process.

[0044] In one embodiment of this application, please continue to combine Figure 6 and Figure 7 Both the first beam 223 and the second beam 224 are U-shaped plates. The first beam 223 includes a first bottom 2231 and a first top 2232 protruding from the first bottom 2231. The second beam 224 includes a second bottom 2241 and a second top 2242 protruding from the second bottom 2241. The first bottom 2231 is connected to the second bottom 2241, and the first top 2232 is opposite to the second top 2242. The first bottom 2231, the second bottom 2241, the first top 2232, and the second top 2242 are all connected. Together, they form a first cavity 221; the second support reinforcement 25 includes a main body 253, a first connecting portion 251 and a second connecting portion 252 extending from both ends of the main body 253 to a second bottom 2241 and a second top 2242 respectively; the first connecting portion 251 connects to the second bottom 2241 and together with the first bottom 2231 and the second bottom 2241, forms a three-layer connection structure; the second connecting portion 252 connects to the second top 2242 and together with the second top 2242 and the first reinforcement 24, forms a three-layer connection structure.

[0045] Specifically, both the first beam 223 and the second beam 224 are channel plates, and their cross-sections are both channel-shaped. The two first bottoms 2231 respectively connect to the two second bottoms 2241 correspondingly, and the first top 2232 and the second top 2242 face each other, so that the cavities of the first beam 223 and the second beam 224 can be combined to form an independent cavity, that is, the first cavity 221. Looking along the second direction D2, the cross-section of the first cavity 221 is square-shaped, which can enhance the ability of the first cavity 221 to absorb and relieve external forces, and further enhance the structural strength and collision performance of the subframe 1.

[0046] Furthermore, the plate body 242 of the first reinforcing member 24 can be welded and fixed on the second top 2242, and even extend to the corner of the second top 2242 towards the second bottom 2241, thereby enhancing the structural strength of the second beam 224. The concave portion 241 and the second top 2242 together enclose the fourth cavity 243. On the one hand, it can enhance the structural strength of the first cavity 221; on the other hand, it can enhance the stability of the cabin side connecting beam 22 in the third direction D3.

[0047] Furthermore, the first top 2232 can be connected to the first support reinforcing member 21, and the second top 2242 can be connected to the support connecting member 23, so that the first beam 223, the second beam 224, the first support reinforcing member 21 and the support connecting member 23 can together form the third cavity 222, and the second beam 224 and the support connecting member 23 can together form the second cavity 232.

[0048] Furthermore, the second support reinforcing member 25 can include an open box-shaped reinforcing member with an overall cross-section presenting an "L" shape. The "L"-shaped box structure can fit the second beam 224 to enhance the connection stability.

[0049] Furthermore, the second support reinforcing member 25 is connected to the second beam 224 through the first connecting portion 251 and the second connecting portion 252. Three-layer connection structures of the second support reinforcing member 25, the second beam 224 and the first beam 223 and three-layer connection structures of the second support reinforcing member 25, the second beam 224 and the first reinforcing member 24 are respectively formed at these two connection points. That is to say, the second beam 224 and the second support reinforcing member 25 simultaneously cover two three-layer connection designs, which can effectively enhance the connection strength of the overall frame structure.

[0050] At this time, one end of the second support reinforcement 25 is connected to the second bottom 2241, and the other end extends along the direction opposite to the second bottom 2241 and connects to the second top 2242, so that the second support reinforcement 25, together with the second top 2242 and the second bottom 2241, can form a fifth cavity 225. Along the first direction D1, the first cavity 221 and the fifth cavity 225 are arranged vertically and can cooperate with each other to provide support, thereby improving the structural strength and collision performance of the subframe 1.

[0051] In one embodiment of this application, as Figure 6 As shown, the connecting assembly 2 also includes a second reinforcing member 26, which is disposed inside the first cavity 221 and outside the fourth cavity 243. The second reinforcing member 26 is connected to the inner wall of the first cavity 221. The second reinforcing member 26 is also connected to the first reinforcing member 24. The first reinforcing member 24, the second reinforcing member 26 and the inner wall of the first cavity 221 together form a sixth cavity 261.

[0052] Specifically, the second top 2242 and the second bottom 2241 can be connected by the connecting side 2243, and the second reinforcing member 26 can be welded and fixed to the side of the connecting side 2243 facing the first cavity 221.

[0053] Furthermore, since the second reinforcing member 26 is disposed on the connecting side 2243 and located outside the fourth cavity 243, the first reinforcing member 24 and the second reinforcing member 26 can together with the connecting side 2243 form the sixth cavity 261. Since the fourth cavity 243 is formed at the second top 2242 and the sixth cavity 261 is formed at the connecting side 2243, along the first direction D1, the fourth cavity 243 and the sixth cavity 261 can present a hierarchical structural relationship. They contact the second reinforcing member 26 through the arc-shaped support surface of the recess 241, thereby achieving mutual support between the fourth cavity 243 and the sixth cavity 261, thus improving load-bearing capacity and collision performance.

[0054] Furthermore, the connection between the second reinforcing member 26 and the first reinforcing member 24 can make the cavity structure of the sixth cavity 261 form a closed structure, thereby further improving its structural performance.

[0055] In one embodiment of this application, the two ends of the second reinforcing member 26 are respectively connected to the first beam 223 and the first reinforcing member 24, and the second reinforcing member 26 together with the first beam 223 and the first reinforcing member 24 form a three-layer connection structure.

[0056] Specifically, the overall structure of the second reinforcing member 26 can be a facade design, with one end connected to the recess 241 of the first reinforcing member 24, and the other end extending in the direction opposite to the recess 241 to connect to the first beam 223, and located in the middle of the first cavity 221, so that the second reinforcing member 26, the first beam 223 and the first reinforcing member 24 form a reinforced three-layer connection structure, which can improve vertical stability and increase the structural strength of the first cavity 221.

[0057] In one embodiment of this application, combined with Figures 1 to 7 As shown, the subframe 1 is provided with a seventh cavity 11, which is an arc-shaped cavity along the second direction. The first cavity 221, the third cavity 222 and the seventh cavity 11 are arranged along the first direction D1 and are in a stepped shape.

[0058] Specifically, in some embodiments, the subframe 1 has a seventh cavity 11 inside. By designing a cavity structure in the mounting point area of ​​the subframe 1, the structural strength of the subframe 1 can be further improved, the connection strength with the vehicle body can be improved, and the collision performance can be improved.

[0059] In one embodiment of this application, the connecting component 2 further includes a reinforcing sleeve 28 and a connecting fastener 29. The reinforcing sleeve 28 is located in the third cavity 222. The subframe 1 is provided with a subframe sleeve 12 inside, and the subframe sleeve 12 communicates with the reinforcing sleeve 28. The connecting fastener 29 passes through the subframe sleeve 12 and the reinforcing sleeve 28 to connect and fix the connecting component 2 and the subframe 1.

[0060] Specifically, the subframe 1 is provided with a subframe sleeve 12 that penetrates the seventh cavity 11. The subframe sleeve 12 may include a steel cylindrical sleeve design, which is welded and fixed at the internal mounting point of the subframe 1 to improve the structural strength of the mounting point of the subframe 1 and also to improve the connection stability with the vehicle body. In addition, the subframe sleeve 12 has an "L" shaped cross-section, and its top along the first direction D1 is designed as an end face flange 121. The end face flange 121 is directly welded to the upper end face of the subframe 1 and connected to the second support reinforcement 25. This design can effectively increase the connection area, improve vertical stability, and enhance the strength of the frame structure.

[0061] Furthermore, the reinforcing sleeve 28 is disposed inside the third cavity 222, with its first end connected to the second support reinforcement 25, and its second end extending in a direction opposite to the subframe 1 to pass through the third cavity 222 and enter the first cavity 221. The first end of the reinforcing sleeve 28 is directly opposite the end face flange 121 of the subframe sleeve 12, so that the reinforcing sleeve 28 is in communication with the subframe sleeve 12. Then, fasteners 29, such as long bolts or long rivets, can pass through the subframe sleeve 12 and the reinforcing sleeve 28 to connect and fix the connecting assembly 2 and the subframe 1.

[0062] Furthermore, along the first direction D1, the first cavity 221, the third cavity 222, and the seventh cavity 11 are stacked together in a stepped arrangement, corresponding to each other. In use, the energy transmitted from the connecting fastener 29 includes: the load during driving, the load of the whole vehicle, the force under collision conditions, and the force under torsion conditions. The energy is transmitted through the eighth cavity 234 to the third cavity 222, and then from the third cavity 222 to the first cavity 221. The three cavities absorb and alleviate the load one by one. This "three-layer stepped" cavity structure design greatly strengthens the entire frame structure. Moreover, the "three-layer stepped" cavity structure design can be an irregular cavity structure. Irregular cavities have higher efficiency in buffering and attenuating force during the force transmission process, thereby further improving the structural strength and collision performance of the subframe 1.

[0063] Furthermore, the second reinforcing member 26 is provided with an arc-shaped flange, which can be fitted onto the outer periphery of the reinforcing sleeve 28 and welded to the reinforcing sleeve 28. The overall structure is a vertical design, which can improve the vertical stability of the reinforcing sleeve 28 so that it will not deflect under high stress conditions, thereby improving the installation strength.

[0064] In one embodiment of this application, please refer to... Figure 4 and Figure 8 , Figure 8 yes Figure 1 The diagram shows a partial enlarged view of the structure. The first support reinforcement 21 includes a third connecting part 211 and a fourth connecting part 212 that are bent and connected. The third connecting part 211 is connected to the first end of the first through groove 231, and the fourth connecting part 212 is disposed facing the first through groove 231. The connecting assembly 2 also includes a third reinforcement 27, which is disposed on the third connecting part 211 and located in the third cavity 222. The third reinforcement 27 divides the third cavity 222 into a first sub-cavity 2221 and a second sub-cavity 2222.

[0065] Specifically, at the first end of the cabin side connecting beam 22, the cabin side connecting beam 22 is connected to the first support reinforcement 21 through the second beam 224 and to the support connector 23 through the first beam 223. That is, the fourth connecting part 212 is connected to the second top 2242, and the support connector 23 is connected to the first top 2232, so that the cabin side connecting beam 22, the first support reinforcement 21 and the support connector 23 together form a third cavity 222.

[0066] Furthermore, the third reinforcing member 27 can also be directly opposite the mounting point of the subframe 1 and divide the third cavity 222 into a first sub-cavity 2221 and a second sub-cavity 2222. That is, the partition between the first sub-cavity 2221 and the second sub-cavity 2222 is directly opposite the mounting point of the subframe 1. This design can improve the load-bearing capacity of the mounting point of the subframe 1, and at the same time, it can also improve the collision resistance of the subframe 1.

[0067] In one embodiment of this application, both ends of the third reinforcing member 27 are connected to the inner wall of the third connecting part 211 and the first through groove 231, and together with the inner wall of the third connecting part 211 and the first through groove 231, they form a three-layer connection structure.

[0068] Specifically, the third reinforcing member 27 is disposed on the third connecting portion 211, i.e., located inside the third cavity 222. The third reinforcing member 27 may include a reinforcing member with an overall vertical design, and its first end is provided with a bent flange 271. The bent flange 271 and the body of the third reinforcing member 27 are arranged in an "L" shape. By connecting the bent flange 271 to the third connecting portion 211, the third reinforcing member 27 can stand upright inside the third cavity 222 to improve vertical stability. The two second ends of the third reinforcing member 27 adjacent to the first end can be effectively connected to the flanges of the first supporting reinforcing member 21 and the supporting connecting member 23, and are located in the middle position of the third cavity 222, thereby forming a reinforced three-layer connection structure to further improve vertical stability.

[0069] Furthermore, such as Figure 8 As shown, the third reinforcing member 27 is also provided with an arc-shaped flange. The arc-shaped flange can surround the outer periphery of the reinforcing sleeve 28 and be welded to the reinforcing sleeve 28, which can improve the vertical stability of the reinforcing sleeve 28 so that it will not deflect under high stress conditions and effectively improve the installation strength.

[0070] Furthermore, the curved flange structure can also achieve the following effects: on the one hand, it can improve the structural rigidity of the third reinforcing member 27; on the other hand, it can improve the lateral and vertical stability; finally, the curved design is also conducive to energy attenuation and buffering.

[0071] Furthermore, at the first end of the side-connecting beam 22, the reinforcing sleeve 28 is only installed in the third cavity 222. The first support reinforcement 21 is connected and fixed to the subframe 1 by the connecting fastener 29 passing through the subframe sleeve 12 and the reinforcing sleeve 28. The first cavity 221, the third cavity 222 and the seventh cavity 11 are also arranged along the first direction D1 and are stepped, and their effect is the same as that at the second end of the side-connecting beam 22, which will not be described again here.

[0072] In one embodiment of this application, as Figure 5As shown, the support connector 23 is also provided with a protrusion 233. When the support connector 23 is connected to the cabin side connecting beam 22, the protrusion 233 protrudes from the outer wall of the cabin side connecting beam 22; the protrusion 233 and the cabin side connecting beam 22 together form the eighth cavity 234.

[0073] Specifically, in addition to the first through groove 231, the support connector 23 also has structural flanges 235 on both sides of the first through groove 231 for connecting the cabin side connecting beam 22. The structural flanges 235 extend from both sides of the first through groove 231 to both sides. The protrusion 233 is provided on at least one of the structural flanges 235, and when connected to the first beam 223 of the cabin side connecting beam 22, it forms an eighth cavity 234 together with the first top 2232 of the first beam 223. Because the overall cross-section of the support connector 23 is a vertically continuous "U" shape, it can also form a "rectangular" cavity structure at the connection with the first top 2232, namely the eighth cavity 234. By absorbing and mitigating the load through the eighth cavity 234, the structural strength and stability of the first beam 223 can be improved.

[0074] Furthermore, if Figure 6 As shown, at the second end of the side connecting beam 22, the first top 2232 of the first beam 223 also has a protrusion 2233 protruding away from the second beam 224. The protrusion 2233, together with the first top 2232 and the second beam 224, forms the ninth cavity 2234. The ninth cavity 2234, the fourth cavity 243, and the sixth cavity 261 are all auxiliary cavities of the first cavity 221. The ninth cavity 2234 corresponds to the arc-shaped corner area of ​​the first beam 223, and the direction of the arc-shaped corner is outward. This design helps to increase the cross-sectional area of ​​the first cavity 221, thereby improving the strength of the subframe 1. In other words, the ninth cavity 2234 is a reinforced cavity extending outward in the overtaking direction, which increases the cross-sectional dimensions of the entire first cavity in the third direction D3, thereby improving the lateral stability and structural strength of the subframe 1.

[0075] The connecting component 2 in this embodiment connects to the subframe 1 by setting multiple cavity structures, so that the multiple cavities can cooperate with each other to provide support, which can improve the structural strength and collision performance of the subframe 1, as well as simplify the structure, reduce weight, and achieve cost reduction and efficiency improvement.

[0076] It should be noted that the terms "horizontal" and "vertical" do not imply that the components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. Similarly, the terms "parallel" and "perpendicular" do not imply that the components are absolutely parallel or perpendicular, but rather that they can have a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted. In addition, the orientations or positional relationships indicated by terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" are based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships that are commonly used when the product of this application is in use. They are only for the purpose of describing the embodiments of this application and simplifying the description, 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 application.

[0077] It is understood that the term "multiple" in this document means at least two, such as two, three, etc., unless otherwise specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. The term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.
