[0033] The embodiments of this utility model are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0034] The following is for reference. Figures 1-10The vehicle frame assembly 100 according to an embodiment of the present utility model can flexibly seal the perforations 15 on the hollow beam 19 through the sealing component 2, thereby not interfering with the manufacturing process of the vehicle frame 1 through the perforations 15, and ensuring the sealing of the battery frame 13.

[0035] Combination Figures 1-10 As shown, the vehicle frame assembly 100 according to the first aspect of this utility model includes a frame 1 and a sealing assembly 2. The frame 1 is the main supporting structure of the vehicle, providing support for components such as the battery 4, suspension system, and transmission system. It also absorbs impact energy during a collision, protecting the safety of the passenger compartment, and serves as a mounting base for related components.

[0036] Specifically, the frame 1 includes a crossbeam 11 and a longitudinal beam 12, the crossbeam 11 and the longitudinal beam 12 are connected, and the crossbeam 11 and the longitudinal beam 12 together form a closed battery frame 13. At least one of the crossbeam 11 and the longitudinal beam 12 is a hollow beam 19 forming an inner cavity 14. The hollow beam 19 is provided with a through hole 15 communicating with the inner cavity 14. A sealing assembly 2 is provided on the hollow beam 19 and corresponds to the through hole 15 to seal the inner cavity 14.

[0037] Specifically, the crossbeams 11 are spaced apart in the longitudinal direction (i.e., the front-to-back direction of the vehicle), and the longitudinal beams 12 are spaced apart in the transverse direction (i.e., the left-to-right direction of the vehicle). The crossbeams 11 and longitudinal beams 12 are connected to each other and together form a closed battery frame 13. This allows a closed force transmission path to be formed between the crossbeams 11 and longitudinal beams 12, which helps to distribute the loads they receive and thus effectively improves the structural reliability of the frame 1. On the other hand, the battery frame 13 can be integrated into the frame 1, so that the battery frame 13 can replace the traditional battery 4 side frame, thereby increasing the placement space of the battery 4 and increasing the battery capacity.

[0038] Furthermore, the hollow beam 19 is provided with a perforation 15 that communicates with its inner cavity 14, and the sealing assembly 2 can seal the inner cavity 14 at the perforation 15 (that is, the inner cavity 14 is connected to the outside due to the opening of the perforation 15), thereby ensuring the sealing performance of the battery frame 13.

[0039] Specifically, when the perforation 15 on the hollow beam 19 is not sealed with the sealing component 2, the frame 1 can carry out normal production processes through the perforation 15 (such as the perforation 15 can serve as an electrophoresis lifting hole, welding positioning hole, etc.). After the frame 1 completes the specified production process, the operator can seal the inner cavity 14 at the perforation 15 through the sealing component 2, thereby ensuring the sealing of the battery frame 13 and thus ensuring the safety of the battery 4.

[0040] Therefore, by setting up the frame assembly 100, it can flexibly seal the perforations 15 on the hollow beam 19 through the sealing component 2, so as not to interfere with the manufacturing process of the frame 1 through the perforations 15, and to ensure the sealing of the battery frame 13, thereby improving the reliability of the frame assembly 100.

[0041] According to some optional embodiments of the present invention, combined with Figures 4-9 As shown, the sealing assembly 2 includes a seal 21 and a fastener 22. The seal 21 is attached to the wall of the hollow beam 19 and is arranged around the perforation 15. The fastener 22 passes through the seal 21 and the perforation 15.

[0042] As described above, the fastener 22 can cover the perforation 15, and the fastener 22 can also press the seal 21 against the wall of the hollow beam 19, so that the two can work together to achieve a tight connection with the perforation 15, thereby achieving a sealing effect on the inner cavity 14 of the perforation 15 and ensuring the sealing performance of the battery frame 13.

[0043] Specifically, in combination Figures 4-9 As shown, the fastener 22 includes a nut 221 and a bolt 222. The nut 221 is located inside the inner cavity 14 and corresponds to the through hole 15. The bolt 222 passes through the seal 21 and the through hole 15 and then engages with the nut 221 through a thread.

[0044] It is understandable that the bolt 222 passes through the seal 21, the through hole 15 and the nut 221 in sequence to connect and fix the fastener 22, the seal 21, the hollow beam 19 and the nut 221 into a solid whole, thereby improving the positional stability of the seal 21 and ensuring the sealing effect of the hollow beam 19.

[0045] Among them, the nut 221 and the bolt 222 are connected by threads. Compared with other connection methods, this connection method allows operators to quickly disassemble and replace the parts using simple tools (such as wrenches, screwdrivers, etc.). Moreover, the structure is simple, the cost is low, and it can be reused multiple times, thereby improving its ease of disassembly and assembly and its practicality.

[0046] In addition, bolt 222 can achieve a good sealing effect by cooperating with seal 21 (such as a gasket) to prevent liquid or gas leakage, thereby ensuring the sealing performance of hollow beam 19.

[0047] Furthermore, combined Figure 4 and Figure 9 As shown, the hollow beam 19 is provided with a recessed groove 16 facing the inner cavity 14, and a through hole 15 is provided at the bottom of the recessed groove 16. The fastener 22 located in the recessed groove 16 does not protrude from the recessed groove 16 along its length direction.

[0048] Understandably, the hollow beam 19 has a recessed groove 16 on the side facing the inner cavity 14. The groove 16 can increase the spatial modes of the hollow beam 19, thereby enhancing its bending and torsional stiffness. Since the groove 16 is lower than the inner surface of the hollow beam 19, the through hole 15 is opened at the bottom of the groove 16. This allows the head of the fastener 22 near the through hole 15 to fall into the groove 16 without protruding from it. This reduces the space occupied by the fastener 22 within the battery frame 13, thereby improving the effective use of space for the battery 4 within the battery frame 13 and enhancing the rationality of the arrangement.

[0049] Optionally, combined Figure 4 and Figure 9 As shown, the hollow beam 19 is provided with a flat plate area 17, and the flat plate area 17 is provided with a through hole 15. This arrangement, since the surface of the flat plate area 17 is flat, can increase the contact area between the seal 21 and the hollow beam 19, and also increase the force transmission area between the fastener 22 and the hollow beam 19, thereby ensuring the tightness of the connection and the uniformity of the force between the fastener 22, the seal 21 and the hollow beam 19, and thus ensuring the sealing effect of the sealing assembly 2.

[0050] Specifically, in combination Figure 6 , Figure 7 and Figure 9 As shown, the through hole 15 is provided on the inner side wall of the hollow beam 19, and the outer side wall of the hollow beam 19 is provided with a tool through hole 18 for passing through the fastening tool and nut 221. The tool through hole 18 and the through hole 15 correspond to each other in the inner and outer directions.

[0051] It is understandable that the inner and outer walls of the hollow beam 19 are respectively provided with corresponding through holes 15 and tool through holes 18. The tool through holes 18 facilitate the operator to perform disassembly and assembly work in the inner cavity 14 of the hollow beam 19 from the outside of the hollow beam 19 (for example, the operator can insert a tool into the inner cavity 14 of the hollow beam 19 through the tool through holes 18 to tighten the nut 221 and the bolt 222), thereby improving the ease of disassembly and assembly of the sealing assembly 2.

[0052] According to some optional embodiments of the present invention, combined with Figure 4 , Figure 5 , Figure 7 and Figure 10 As shown, the sealing assembly 2 is located inside the inner cavity 14. The sealing assembly 2 includes a mating part 23, a sealing part 21, and a fastener 22. The mating part 23 is located inside the inner cavity 14 and has a mounting hole corresponding to the through hole 15. The sealing part 21 is attached to the mating part 23 and is arranged around the mounting hole. The fastener 22 passes through the sealing part 21 and is installed in the mounting hole.

[0053] As described above, the arrangement can reduce the space occupied by the sealing component 2 on the outside of the inner cavity 14, thereby increasing the effective arrangement space of the battery 4 inside the battery frame 13. On the other hand, it can connect the fastener 22, the sealing component 21 and the mating component 23 into a tight whole after the fastener 22 passes through the sealing component 21 and the mounting hole in sequence, thereby achieving a sealing effect on the inner cavity 14 at the perforation 15 and ensuring the sealing performance of the battery frame 13.

[0054] Specifically, in combination Figure 10 As shown, the mounting hole has an internal thread, and the fastener 22 is a bolt 222, which mates with the internal thread.

[0055] In other words, the bolt 222 is connected and fixed by the internal thread of the mounting hole, which can improve the connection strength between the fastener 22, the seal 21 and the mating part 23, thereby ensuring the positional stability of the sealing assembly 2 and thus ensuring the sealing effect of the hollow beam 19.

[0056] In this connection, the nut 221 and bolt 222 are connected by threads. Compared to other connection methods, this method allows operators to quickly disassemble and replace parts using simple tools (such as wrenches and screwdrivers). Furthermore, it is simple in structure, low in cost, and reusable, thus improving its ease of assembly and disassembly and its practicality. In addition, the bolt 222 can achieve a good sealing effect by cooperating with the sealing element 21 (such as a washer), preventing liquid or gas leakage and ensuring the airtightness of the hollow beam 19.

[0057] Furthermore, combined Figure 10 As shown, the mating part 23 has a mounting cavity 231 that communicates with the through hole 15, and the fastener 22 located in the mounting cavity 231 does not protrude from the mounting cavity 231 along its length direction.

[0058] It is understandable that since the mounting cavity 231 is located inside the inner cavity 14 of the hollow beam 19 and is connected to the through hole 15, the fastener 22 can be pre-passed through the through hole 15 in the direction facing the inner cavity 14, and its head near the through hole 15 can be placed in the mounting cavity 231 without protruding from the mounting cavity 231. This can ensure the sealing effect while reducing the arrangement space occupied by the fastener 22 in the battery frame 13, thereby improving the effective utilization space of the battery 4 in the battery frame 13 and thus improving the battery capacity.

[0059] The edge of the mating part 23 is arranged around the through hole 15. This arrangement makes it easy for the mating part 23 to have a corresponding mounting hole for the through hole 15, thereby ensuring that the mating part 23, when mated with the fastener 22 and the seal 21, can achieve a sealing effect on the inner cavity 14 at the through hole 15. Welded connection has the characteristics of high connection strength and good sealing performance. The edge of the mating part 23 is welded to the side wall of the hollow beam 19, which can improve the sealing reliability.

[0060] Optionally, combined Figure 4 , Figure 5 , Figure 7 and Figure 10 As shown, the mating part 23 includes a connecting part 232 and a main body 233. The connecting part 232 is provided with a mounting hole. The main body 233 is connected to the side of the connecting part 232 near the through hole 15. The main body 233 is ring-shaped, and the inner diameter of the main body 233 is larger than the diameter of the through hole 15. This arrangement makes it easy for the main body 233 to be processed and connected to the solid part of the hollow beam 19 around the through hole 15. Thus, while ensuring that the mating part 23 is tightly connected to the hollow beam 19, the mating part 23 can also cover the through hole 15 in the inner and outer directions, ensuring the sealing effect of the sealing assembly 2.

[0061] According to some optional embodiments of the present invention, combined with Figures 1-3 As shown, the frame assembly 100 also includes a top cover 3 and a battery 4. The top cover 3 is connected to the upper side of the battery frame 13. The battery 4 includes a cell 41 and a tray 42. The cell 41 is mounted on the upper side of the tray 42, and the tray 42 is connected to the lower side of the battery frame 13. The top cover 3, the battery frame 13, and the tray 42 together form a cavity 43 for receiving the cell 41.

[0062] The top cover 3 and the tray 42 are arranged correspondingly in the vertical direction. The top cover 3 and the tray 42 are respectively connected to the upper and lower sides of the battery 4 frame. The top cover 3, the battery frame 13 and the tray 42 together define the cavity 43 for the battery cell 41, which can form a comprehensive protection effect for the battery cell 41, thereby ensuring the sealing and safety of the battery 4.

[0063] Furthermore, since the top cover 3 and tray 42 are connected to the battery frame 13, the weight and spatial mode of the frame 1 can be increased, thereby improving the structural strength and bending and torsional stiffness of the frame 1, and thus improving the structural reliability and handling stability of the whole vehicle.

[0064] Moreover, compared to the traditional vehicle frame assembly solution (where the battery and frame are independent structures), in this case, the frame 1, tray 42, and top cover 3 work together to provide a sealed frame for the battery cell 41. This arrangement eliminates the traditional battery 4 frame, which can effectively increase the space for the battery cell 41, thereby increasing the battery capacity and thus improving the vehicle's range.

[0065] According to the second aspect of the present invention, the vehicle includes the frame assembly 100 of the above embodiment. Thus, the vehicle having the frame assembly 100 can integrate the frame 1 with the battery 4, thereby increasing the space for the battery cell 41 and increasing the battery capacity of the battery 4; it can also ensure the sealing of the battery frame 13, thereby ensuring the safety of the battery 4, and thus improving the market competitiveness of the whole vehicle.
