[0027] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0028] Reference below Figure 1-Figure 3 A vehicle 100 according to an embodiment of the present invention is described.

[0029] Combination Figure 1 As shown, the vehicle 100 according to the utility model may mainly include: a vehicle body 10, a battery pack 20, a first connector 30 and a second connector 40. The battery pack 20 is spaced apart from the vehicle body 10, the first connector 30 is an integrally made structural member, the first connector 30 is connected to the vehicle body 10, the second connector 40 is connected to the battery pack 20, and the second connector 40 is located below the first connector 30 and is detachably connected to the first connector 30 to achieve the connection between the battery pack 20 and the vehicle body 10.

[0030] Specifically, the battery pack 20 is spaced apart from the vehicle body 10. To realize the installation of the battery pack 20, the battery pack 20 needs to be connected to the vehicle body 10. By providing the first connector 30 and the second connector 40, the first connector 30 is connected to the vehicle body 10, and the second connector 40 is connected to the battery pack 20. In this way, the detachable connection between the battery pack 20 and the vehicle body 10 can be realized by only detachably connecting the first connector 30 and the second connector 40. This can not only ensure the connection stability between the battery pack 20 and the vehicle body 10 and the normal operation of the vehicle 100, but also facilitate the disassembly and assembly of the battery pack 20, and facilitate the inspection and replacement of the battery pack 20.

[0031] Furthermore, different from the prior art in which the first connecting member includes threaded bolts and screw sleeves, the present application integrates the threaded bolts and screw sleeves and sets the first connecting member 30 as an integral structural member. On the one hand, this can reduce the number of parts, shorten the assembly steps, and improve assembly efficiency. On the other hand, the threaded connection of the first connecting member 30 itself can be eliminated, which not only reduces the machining and tapping process, improves production efficiency, and reduces production costs, but also reduces sharp edges accordingly, which is beneficial to the adhesion of the electrophoretic liquid in the electrophoretic process, enhances the electrophoretic effect, enhances the anti-corrosion performance of the first connecting member 30, and improves the reliability of the first connecting member 30 and even the vehicle 100.

[0032] Therefore, by connecting the first connecting member 30 to the vehicle body 10, and connecting the second connecting member 40 to the battery pack 20, the second connecting member 40 is located below the first connecting member 30 and is detachably connected to the first connecting member 30, and the first connecting member 30 is an integrally manufactured structural member, which can not only reduce the number of parts and improve the assembly efficiency of the vehicle 100, but also reduce the threaded structure, improve the production efficiency of the first connecting member 30, and improve the corrosion resistance of the first connecting member 30.

[0033] Combination Figure 1 and Figure 2 As shown, a first step portion 31 is provided on the first connecting member 30, the vehicle body 10 includes a front floor lower longitudinal beam 11, a first through hole is provided on the front floor lower longitudinal beam 11, at least a portion of the first connecting member 30 passes through the first through hole, and the first step portion 31 is located above the front floor lower longitudinal beam 11 and is welded to the front floor lower longitudinal beam 11.

[0034] Specifically, by providing a first step portion 31 on the first connecting member 30, the first step portion 31 is arranged downward, and a first through hole is provided on the front floor lower longitudinal beam 11. In this way, during assembly, the first connecting member 30 can be at least partially penetrated from top to bottom through the first through hole. The first step portion 31 can be located above the front floor lower longitudinal beam 11 and overlapped with the front floor lower longitudinal beam 11. Then, the first step portion 31 is welded to the front floor lower longitudinal beam 11. The connection between the first connecting member 30 and the front floor lower longitudinal beam 11 can be achieved, and the connection between the first connecting member 30 and the vehicle body 10 can be simpler and more reliable.

[0035] Combination Figure 1 and Figure 3 As shown, a second step portion 41 is provided on the second connecting member 40, the battery pack 20 includes a side beam 21, the side beam 21 is provided with a second through hole, at least a portion of the second connecting member 40 is penetrated by the second through hole, and the second step portion 41 is located below the side beam 21 and is welded to the side beam 21.

[0036] Specifically, by providing a second step portion 41 on the second connecting member 40, the second step portion 41 is arranged upward, and a second through hole is provided on the side beam 21. In this way, during assembly, the second connecting member 40 can be firstly penetrated at least partially from bottom to top through the second through hole, the second step portion 41 can be located below the side beam 21 and overlap the side beam 21, and then the second step portion 41 and the side beam 21 can be welded. The connection between the second connecting member 40 and the side beam 21 can be achieved, and the connection between the second connecting member 40 and the battery pack 20 can be made simpler and more reliable.

[0037] Combination Figure 2 and Figure 3 As shown, the vehicle 100 may further include: a fastener, the first connecting member 30 is provided with a first mounting hole 32, the second connecting member 40 is provided with a second mounting hole 42, the second mounting hole 42 corresponds to the first mounting hole 32, the fastener passes through the second mounting hole 42 and the first mounting hole 32 and is connected and fixed to the first connecting member 30.

[0038] Specifically, by setting a first mounting hole 32 on the first connecting member 30, setting a second mounting hole 42 on the second connecting member 40, and making the second mounting hole 42 correspond to the first mounting hole 32, after connecting the first connecting member 30 to the vehicle body 10 and connecting the second connecting member 40 to the battery pack 20, it is only necessary to align the mounting surfaces of the first connecting member 30 and the second connecting member 40, make the first mounting hole 32 correspond to the second mounting hole 42, and then pass the fastener through the second mounting hole 42 and the first mounting hole 32, and connect and fix the fastener to the first connecting member 30, so as to realize the detachable connection between the first connecting member 30 and the second connecting member 40, and make the detachable connection between the first connecting member 30 and the second connecting member 40 simpler and more reliable.

[0039] Furthermore, the fastener is a mounting bolt, the second mounting hole 42 is a through hole, the inner wall of the first mounting hole 32 is provided with a threaded portion 321 , and the mounting bolt is threadedly connected to the threaded portion 321 .

[0040] Specifically, the fastener can be set as a mounting bolt, and correspondingly, a threaded portion 321 is set on the inner wall of the second connecting member 40 corresponding to the first mounting hole 32. In this way, it is only necessary to first pass the mounting bolt through the second mounting hole 42 of the second connecting member 40, and then continue to penetrate into the first mounting hole 32, and make the mounting bolt threadedly connected with the threaded portion 321, so as to achieve a stable connection between the second connecting member 30 and the second connecting member 40.

[0041] Furthermore, compared to setting the threaded portion at both the first mounting hole and the second mounting hole, by setting the second mounting hole 42 as a through hole and not setting the threaded portion 321 thereon, but only setting the threaded portion 321 at the first mounting hole 32, the threaded structure of the vehicle 100 can be further reduced, which can not only further reduce the machining and tapping process, improve production efficiency, and reduce production costs, but also further reduce sharp edges, which is beneficial to the adhesion of the electrophoretic fluid in the electrophoretic process, enhance the electrophoretic effect, and enhance the anti-corrosion performance.

[0042] Combination Figure 2 and Figure 3 As shown, the mounting bolt may include a rod and a head, the head is arranged at one end of the rod, the second mounting hole 42 may include a first hole portion 421 and a second hole portion 422 connected to each other, the head is arranged in the first hole portion 421, the rod passes through the second hole portion 422 and is threadedly connected to the threaded portion 321.

[0043] Specifically, the fastener can be set as a mounting bolt. Considering that the mounting bolt includes a head and a rod, by making the second mounting hole 42 include a first hole portion 421 and a second hole portion 422 connected to each other, the diameter of the first hole portion 421 is larger than the diameter of the second hole portion 422, and when the mounting bolt is passed through the second mounting hole 42, the rod portion will pass through the second hole portion 422 and finally be threadedly connected with the threaded portion 321 of the first connecting member 30, and the head can be set in the first hole portion 421, and the head abuts against the inner wall of the first hole portion 421 in the front-to-back direction. In this way, under the premise of ensuring that the mounting bolt stably connects the first connecting member 30 and the second connecting member 40, the head can be hidden in the first hole portion 421, and the head can be avoided from protruding from the second connecting member 40, which can not only protect the head and improve the structural reliability, but also avoid the head from affecting the normal operation of the battery pack 20.

[0044] In some embodiments of the present invention, the material of the first connecting member 30 may include SWRCH10A.

[0045] Specifically, SWRCH10A can be formed by metal plastic processing at room temperature, and has excellent processing performance. In addition, the SWRCH10A material has a tight internal structure, high wear resistance, very high strength limit and elastic limit, and good mechanical properties. By making the first connecting member 30 include SWRCH10A, the structural strength and service life of the first connecting member 30 can be improved, thereby improving the quality and durability of the first connecting member 30.

[0046] Furthermore, the first connecting member 30 is a cold-forged structural member. Specifically, by machining the first connecting member and setting the first connecting member 30 as a cold-forged structural member, not only can the mechanical properties of the first connecting member 30 be improved, the product accuracy and performance requirements of the first connecting member 30 be ensured, but also the production efficiency of the first connecting member 30 can be greatly improved, the material loss rate can be reduced, and the production cost can be saved.

In addition, the SWRCH10A material has a tight internal structure, high wear resistance, very high strength limit and elastic limit, etc., and good mechanical properties. By making the material of the second connecting member 40 include SWRCH10A, the structural strength and service life of the second connecting member 40 can be improved, thereby improving the quality and durability of the second connecting member 40.

[0048] Furthermore, the second connecting member 40 is a cold-forged structural member. Specifically, by machining the second connecting member and setting the second connecting member 40 as a cold-forged structural member, not only can the mechanical properties of the second connecting member 40 be improved, the product accuracy and performance requirements of the second connecting member 40 be ensured, but also the production efficiency of the second connecting member 40 can be greatly improved, the material loss rate can be reduced, and the production cost can be saved.
