[0029] With the rapid development of the automotive industry, people's requirements for vehicle collision safety are gradually increasing. The frame of a car is formed by the interconnection of various components, and the connection between these components has a significant impact on the car's collision performance. In the frame beams of the vehicle body structure, there are often multiple reinforcing beams overlapping each other. However, the structural design of traditional overlapping joints of multiple reinforcing beams is generally quite complex, and the force transmission effect at the joints is poor.

[0030] To address the related technical problems, this application provides a vehicle that includes the following vehicle body components.

[0031] To address the related technical problems, this application also provides a vehicle body component, for details please refer to [link / reference needed]. Figures 1 to 3 , Figure 1 This is a first-view structural schematic diagram of an embodiment of the connector provided in this application; Figure 2 yes Figure 1 A second-view structural schematic diagram of the connecting joint; Figure 3 yes Figure 1 A third-view structural schematic diagram of the connecting joint.

[0032] The vehicle body assembly includes at least one vehicle body crossbeam (not shown), at least one vehicle body longitudinal beam (not shown), and a connecting joint 10. Each vehicle body crossbeam extends along a first direction X; each vehicle body longitudinal beam extends along a second direction Z; the connecting joint 10 is provided with at least one longitudinal beam mounting groove 120 and at least one crossbeam mounting groove 110, the longitudinal beam mounting groove 120 and the crossbeam mounting groove 110 are arranged adjacent to each other, the crossbeam mounting groove 110 extends along the first direction X, each vehicle body crossbeam and at least one crossbeam mounting groove 110 are interlocked, the longitudinal beam mounting groove 120 extends along the second direction Z, each vehicle body longitudinal beam and at least one longitudinal beam mounting groove 120 are interlocked, wherein the first direction X and the second direction Z are intersecting.

[0033] At least one body crossbeam and at least one body longitudinal beam are used to form a body assembly, which can improve the structural strength of the body assembly. The body assembly is connected to the vehicle body, which can improve the structural strength of the vehicle body frame. Each body crossbeam extends in a first direction X, which can be understood as the width direction of the vehicle. Each body longitudinal beam extends in a second direction Z, which can be understood as the height direction of the vehicle. Each body longitudinal beam and each body crossbeam have cavities inside, which provides both good structural strength and light weight. The number of body crossbeams and body longitudinal beams can be 1, 2, or 3, etc., and the specific number can be set according to the actual situation.

[0034] The connecting joint 10 is used to connect each body crossbeam and each body longitudinal beam. The connecting joint 10 includes at least one crossbeam mounting slot 110 and at least one longitudinal beam mounting slot 120. Each body crossbeam can be interlocked with at least one crossbeam mounting slot 110, and each body longitudinal beam can be interlocked with at least one longitudinal beam mounting slot 120. Interlocking means that one end of the body crossbeam can be inserted into the crossbeam mounting slot 110, i.e., the outer side wall of the body crossbeam is connected to the inner side wall of the crossbeam mounting slot 110; or, one end of the body crossbeam is sleeved outside the crossbeam mounting slot 110, i.e., the inner side wall of the body crossbeam is connected to the outer side wall of the crossbeam mounting slot 110. The body longitudinal beams can also be connected to the longitudinal beam mounting slots 120 in either of these two ways. Of course, the connection methods for each body crossbeam and each body longitudinal beam can be different or the same. The crossbeam mounting groove 110 can extend in the same direction as the vehicle body crossbeam, and the longitudinal beam mounting groove 120 can extend in the same direction as the vehicle body longitudinal beam. The crossbeam mounting groove 110 and the vehicle body crossbeam, as well as the longitudinal beam mounting groove 120 and the vehicle body longitudinal beam, can be connected to each other by welding, bolts, or waterproof bonding. The longitudinal beam mounting groove 120 and the crossbeam mounting groove 110 are arranged adjacent to each other, allowing the vehicle body crossbeam and longitudinal beam to be inserted into the connecting joint 10 with a relatively short distance between them, and ensuring that the ends of the vehicle body crossbeam and longitudinal beam connected to the connecting joint 10 are separated only by one wall of the connecting joint 10.

[0035] As an example, the number of body crossbeams can be the same as the number of crossbeam mounting slots 110, that is, one body crossbeam is inserted into a corresponding crossbeam mounting slot 110. The number of body longitudinal beams and longitudinal beam mounting slots 120 can also be the same and correspond one-to-one. As another example, the number of body crossbeams can be less than the number of crossbeam mounting slots 110, that is, one body crossbeam is inserted into multiple adjacent crossbeam mounting slots 110 simultaneously. The relationship between the number of body longitudinal beams and longitudinal beam mounting slots 120 can also be as described above. As yet another example, the number of body crossbeams can be more than the number of crossbeam mounting slots 110, and multiple body crossbeams can be inserted into one crossbeam mounting slot 110 together. For example, some body crossbeams are inserted into the crossbeam mounting slot 110, and one end of some body crossbeams is fitted onto the outer wall of the crossbeam mounting slot 110; or, multiple body crossbeams are inserted into one crossbeam mounting slot 110. This can effectively improve the structural strength of the vehicle body components.

[0036] Through the above-described embodiments, the longitudinal beam mounting groove 120 and the crossbeam mounting groove 110 can position the vehicle body longitudinal beams and crossbeams, simplifying the connection process. They also increase the contact area between the longitudinal beam mounting groove 120 and the vehicle body longitudinal beams, and between the crossbeam mounting groove 110 and the vehicle body crossbeams, enhancing the shear resistance of the connection joint 10 and the connection between the vehicle body crossbeams and longitudinal beams. Furthermore, they allow the vehicle body crossbeams and longitudinal beams to be closer together, resulting in a shorter force transmission path and better force transmission effect.

[0037] In some embodiments, at least one beam mounting groove 110 is provided with at least one beam reinforcing rib 114, and each beam reinforcing rib 114 spans across two opposite inner sidewalls of the beam mounting groove 110 within the beam mounting groove 110.

[0038] At least one crossbeam mounting slot 110 is provided with at least one crossbeam reinforcing rib 114. For example, one or more crossbeam reinforcing ribs 114 may be provided in one crossbeam mounting slot 110; or, when there are multiple crossbeam mounting slots 110, one or more crossbeam reinforcing ribs 114 may be provided in each crossbeam mounting slot 110. The multiple crossbeam reinforcing ribs 114 may be spaced apart in the third direction Y, which intersects the second direction Z and the first direction X in pairs. The third direction Y can be understood as the length direction of the vehicle. The specific number of crossbeam reinforcing ribs 114 can be set according to the actual situation. The crossbeam reinforcing ribs 114 may extend in the second direction Z and span across the two opposite inner sidewalls of the crossbeam mounting slot 110. The second direction Z can be understood as the height direction of the vehicle. Therefore, the crossbeam reinforcing ribs 114 are mainly used to bear the load from the second direction Z to improve the structural strength of the crossbeam mounting slot 110. The crossbeam reinforcing rib 114 can also be connected to the bottom wall of the crossbeam mounting groove 110, which can further improve the structural strength of the crossbeam mounting groove 110. Of course, in some other embodiments, the crossbeam reinforcing rib 114 can also extend in other directions. In addition, the side of the crossbeam reinforcing rib 114 away from the bottom wall of the crossbeam mounting groove 110 can be an inclined side, which extends obliquely from one inner side wall of the crossbeam mounting groove 110 to the opposite inner side wall, which can both improve the structural strength of the crossbeam mounting groove 110 and reduce the weight of the crossbeam reinforcing rib 114.

[0039] In some embodiments, the number of beam mounting slots 110 is at least three, and the at least three beam mounting slots 110 are arranged along the second direction Z. Each beam mounting slot 110 is provided with at least one beam reinforcing rib 114. The beam reinforcing rib 114 in the middle beam mounting slot 110 at least partially overlaps with the orthographic projection of the beam reinforcing rib 114 in one of the adjacent beam mounting slots 110 in the second direction Z. The beam reinforcing rib 114 in the middle beam mounting slot 110 does not overlap with the orthographic projection of the beam reinforcing rib 114 in another adjacent beam mounting slot 110 in the second direction Z.

[0040] The number of beam mounting slots 110 can be three, or more, such as four, five, or six. In this embodiment, there are three beam mounting slots 110 arranged along the second direction Z. Each beam mounting slot 110 contains at least one beam reinforcing rib 114. The beam reinforcing rib 114 in the middle beam mounting slot 110 at least partially overlaps with the orthographic projection of the beam reinforcing rib 114 in one of the adjacent beam mounting slots 110 in the second direction Z, while its orthographic projection does not overlap with that of the beam reinforcing rib 114 in another adjacent beam mounting slot 110. Thus, the overlapping and staggered beam reinforcing ribs 114 can form a stepped stress distribution structure, creating staggered support between different beam mounting slots 110. This not only provides better structural strength in local areas but also disperses stress concentration areas through staggered arrangement, thereby improving the overall load-bearing capacity of the connecting joint 10. As an example, the beam reinforcing ribs 114 of the middle beam mounting groove 110 may coincide with the orthographic projection of the beam reinforcing ribs 114 of the lower beam mounting groove 110 in the second direction Z, and the number of beam reinforcing ribs 114 in the middle beam mounting groove 110 is the same as that in the lower beam mounting groove 110. The beam reinforcing ribs 114 of the middle beam mounting groove 110 may not coincide with the orthographic projection of the beam reinforcing ribs 114 of the upper beam mounting groove 110 in the second direction Z, and the number of beam reinforcing ribs 114 in the upper beam mounting groove 110 may be greater than that in the middle beam mounting groove 110. This improves the force transmission performance between the two beam reinforcing grooves where the projections of the beam reinforcing ribs 114 coincide, and also increases the force transmission path between the two beam reinforcing grooves where the projections of the beam reinforcing ribs 114 do not coincide, thus improving the force transmission performance.

[0041] In some embodiments, at least two adjacent beam mounting slots 110 have trapezoidal cross-sections. Specifically, the beam mounting slot 110 located in the middle is the first mounting slot 111, the beam mounting slot 110 located on the lower side is the second mounting slot 112, and the beam mounting slot 110 located on the upper side is the third mounting slot 113. The cross-sections of the first mounting slot 111 and the second mounting slot 112 are trapezoidal, thereby giving the beam mounting slots 110 better structural strength. In addition, the sidewalls of the first mounting slot 111 and the second mounting slot 112 can also correspond to each other to form a larger trapezoidal cross-section, which can improve the force transmission performance between the first mounting slot 111 and the second mounting slot 112, and further improve the structural strength of the connecting joint 10. In some other embodiments, the cross-section of the third mounting slot 113 can also be a trapezoidal cross-section, and the third mounting slot 113 can form a larger trapezoidal cross-section with the sidewall of the second mounting slot 112, or the third mounting slot 113, the second mounting slot 112, and the first mounting slot 111 can together form a larger trapezoidal cross-section.

[0042] In some embodiments, there are multiple beam mounting slots 110, which are located on the same side and arranged along the second direction Z, and the slot openings of the multiple beam mounting slots 110 face the same direction.

[0043] Multiple crossbeam mounting slots 110 are arranged along the second direction Z, with the slot openings of the multiple crossbeam mounting slots 110 facing the same direction. Multi-point support is achieved through the parallel distribution of multiple crossbeam mounting slots 110. Three or more crossbeam mounting slots 110 can be used, with the slot openings positioned horizontally or inclined. The cross-sectional shape of the crossbeam mounting slots 110 can be rectangular or trapezoidal, depending on the connection requirements. During installation, the crossbeam mounting slots 110 are positioned and fixed by interlocking with the vehicle body crossbeams. Multiple crossbeam mounting slots 110 share the load, accommodating the installation needs of multiple vehicle body crossbeams while maintaining a strong and compact structure. Thus, the parallel distribution of multiple crossbeam mounting slots 110 disperses the load, improving the load-bearing capacity of the connecting joint 10. The uniformly oriented slot design eliminates the need for orientation adjustments during installation, improving assembly efficiency.

[0044] In some embodiments, the crossbeam mounting groove 110 located in the middle in the second direction Z protrudes further in the first direction X from the crossbeam mounting grooves 110 located on both sides in the second direction Z.

[0045] The central crossbeam mounting groove 110 protrudes more in the first direction X than the crossbeam mounting grooves 110 on both sides. Specifically, the first mounting groove 111 protrudes beyond the adjacent second mounting grooves 112 and third mounting grooves 113, forming a stepped structure with the adjacent second and third mounting grooves 112 and 113, thereby improving the structural strength of the connecting joint 10. Furthermore, the greater protrusion of the first mounting groove 111 increases the connection area between the vehicle body crossbeam and the first mounting groove 111, improving force transmission performance. Multiple vehicle body crossbeams can be provided, with one crossbeam corresponding to one mounting groove 110. These multiple mounting grooves 110 are arranged along the second direction Z. Therefore, the greater protrusion of the first mounting groove 111 also increases the connection area between the two vehicle body crossbeams located on either side of the first mounting groove 111 and the connecting joint 10, effectively improving the structural strength and force transmission performance at the connection between the connecting joint 10 and each vehicle body crossbeam.

[0046] In this embodiment, the third mounting groove 113 may include a protrusion and a recess. The two ends of the protrusion in the second direction Z are respectively connected to the recess and the first mounting groove 111, thereby forming a stepped structure within the third mounting groove 113. The first mounting groove 111 also protrudes from the third mounting groove 113, thus forming two stepped structures with the third mounting groove 113, effectively improving the structural strength of the connecting joint 10. Furthermore, the third mounting groove 113 may be provided with multiple crossbeam reinforcing ribs 114, which connect the recess, the protrusion, and the outer wall of the first mounting groove 111 in the second direction Z, thereby improving the structural strength of the third mounting groove 113.

[0047] In some embodiments, at least one longitudinal beam reinforcing rib 123 is provided in at least one longitudinal beam mounting groove 120, and each longitudinal beam reinforcing rib 123 is connected to at least two inner sidewalls of the longitudinal beam mounting groove 120.

[0048] At least one longitudinal beam reinforcing rib 123 disposed within the longitudinal beam mounting groove 120 forms a stable support structure by connecting at least two inner sidewalls of the longitudinal beam mounting groove 120. For example, the longitudinal beam reinforcing rib 123 may connect two adjacent inner sidewalls of the longitudinal beam mounting groove 120; or connect two opposite inner sidewalls; or connect two or more inner sidewalls connected sequentially in the same direction. The longitudinal beam reinforcing rib 123 may extend in the second direction Z, thereby providing better support in the second direction Z. The number of longitudinal beam reinforcing ribs 123 may be multiple, with multiple longitudinal beam reinforcing ribs 123 extending in the second direction Z and spaced apart in the third direction Y. Thus, by providing longitudinal beam reinforcing ribs 123 connecting at least two inner sidewalls within the longitudinal beam mounting groove 120, the stress of the connecting joint 10 at the longitudinal beam mounting groove 120 can be effectively dispersed, and the bending and torsional resistance of the connecting joint 10 can also be improved.

[0049] In some embodiments, the number of longitudinal beam mounting slots 120 is at least two, and the at least two longitudinal beam mounting slots 120 are located on different sides in the second direction Z, and the slot openings of the longitudinal beam mounting slots 120 located on different sides face opposite directions.

[0050] The longitudinal beam mounting slot 120 is used in the vehicle body assembly for insertion with the vehicle body longitudinal beam. There can be two or more longitudinal beam mounting slots 120, with at least two longitudinal beam mounting slots 120 distributed on different sides in the second direction Z, and the slot openings of the two longitudinal beam mounting slots 120 facing opposite directions. In this embodiment, the longitudinal beam mounting slot 120 includes a fourth mounting slot 121 and a fifth mounting slot 122. The fourth mounting slot 121 is located on the side of the crossbeam mounting slot 110 opposite to the slot opening direction, and the fifth mounting slot 122 is located on the same side as the crossbeam mounting slot 110. The slot opening of the fourth mounting slot 121 faces downwards in the second direction Z, and the slot opening of the fifth mounting slot 122 faces upwards in the second direction Z. This allows the connecting joint 10 to insert multiple vehicle body longitudinal beams in different directions. The dimensions of the fourth mounting slot 121 and the fifth mounting slot 122 can be different, thereby allowing connection of vehicle body longitudinal beams of different sizes and making the load transmission path more direct.

[0051] The fourth mounting groove 121 can be formed on the side of the first mounting groove 111, the second mounting groove 112, and the protrusion away from the direction of their openings. That is, the bottom walls of the first mounting groove 111, the second mounting groove 112, and the protrusion serve as part of the side walls of the fourth mounting groove 121. This allows the longitudinal beams and transverse beams of the vehicle body to be inserted closer together after being connected to the connecting joint 10, improving the force transmission performance of the longitudinal beams, transverse beams, and connecting joint 10. The fifth mounting groove 122 is connected to the end of the third mounting groove 113 away from the first mounting groove 111. One end of the crossbeam reinforcing rib 114 of the third mounting groove 113 is connected to the bottom wall of the fifth mounting groove 122, and the other end is connected to the side wall of the protrusion (that is, the other end is connected to the outside of the bottom wall of the fourth mounting groove 121), thereby improving the force transmission performance between the fourth mounting groove 121 and the fifth mounting groove 122.

[0052] In some embodiments, the connecting joint 10 further includes a shock absorber mounting portion 130, which is located between two longitudinal beam mounting slots 120 and protrudes from each longitudinal beam mounting slot 120 in a first direction X toward a direction away from the crossbeam mounting slot 110.

[0053] Specifically, the shock absorber mounting portion 130 can be formed by a recess in the third mounting groove 113. The recess protrudes from each longitudinal beam mounting groove 120 in the first direction X, away from the groove opening, so that the shock absorber mounting portion 130 has sufficient space to connect the shock absorber. The shock absorber mounting portion 130 can be connected to the shock absorber by bolts. The shock absorber mounting portion 130 can be provided with a connecting sleeve located in the recess. The shock absorber mounting portion 130 is fixedly connected to the shock absorber by the connecting sleeve and bolts. Multiple crossbeam reinforcing ribs 114 are provided in the recess, some of which are located on the outside of the connecting sleeve, thereby improving the structural strength of the shock absorber mounting portion 130 and the stability of the connection between the shock absorber and the connecting joint 10.

[0054] In some embodiments, the shock absorber mounting portion 130 includes a mounting body 131 and at least one main body reinforcing rib 132, the at least one main body reinforcing rib 132 being connected to the outer wall of at least one of the longitudinal beam mounting grooves 120.

[0055] The mounting body 131 is provided with screw holes for connection with the shock absorber. A main body reinforcing rib 132 connects the outer side of the mounting body 131 and the outer side of the fifth mounting groove 122. The main body reinforcing rib 132 can be a sloping support structure, and its arrangement includes, but is not limited to, forming a vertically connected reinforcing channel with adjacent structures. There can be multiple main body reinforcing ribs 132; some main body reinforcing ribs 132 connect the mounting body 131 and the fifth mounting groove 122, and some main body reinforcing ribs 132 connect the fourth mounting groove 121. This improves the force transmission performance between the longitudinal beam mounting groove 120 and the shock absorber mounting part 130. The mounting body 131 may include two protrusions and a recess located between the two protrusions. The recess is recessed relative to the two protrusions in the first direction X towards the transverse beam mounting groove 110. The two protrusions are connected to the shock absorber, and each protrusion may be connected to at least one main body reinforcing rib 132, thereby improving both the structural strength of the shock absorber mounting part 130 itself and the connection strength between the shock absorber mounting part 130 and the shock absorber.

[0056] In summary, the longitudinal beam mounting groove 120 and the crossbeam mounting groove 110 can position the longitudinal beams and crossbeams of the vehicle body, simplifying the connection process. They also increase the contact area between the longitudinal beam mounting groove 120 and the longitudinal beams, and between the crossbeam mounting groove 110 and the crossbeams, enhancing the shear resistance at the connection points between the connecting joint 10 and the crossbeams and longitudinal beams. Furthermore, they allow the crossbeams and longitudinal beams to be closer together, resulting in a shorter force transmission path and better force transmission performance.
