Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] REFERENCE Figures 1-6 A battery pack mounting structure, comprising a battery pack 1 and a mounting shell 2 for mounting the battery pack 1, the mounting shell 2 is provided with a rim on each side, a plurality of grooves 3 are formed in the lower surfaces of the rims of the mounting shell 2, a plurality of clamping blocks 4 are fixedly connected to the periphery of the battery pack 1, the clamping blocks 4 are triangular, the lower surfaces of the clamping blocks 4 are parallel to the upper surfaces of the rims of the mounting shell 2, the battery pack 1 is positioned and mounted in the mounting shell 2 through the plurality of clamping blocks 4 and the plurality of through slots 503, the upper surfaces of the rims of the mounting shell 2 are respectively provided with support assemblies 5 for supporting the clamping blocks 4, the support assembly 5 comprises a support plate 501 and a sliding rail 502 for sliding the support plate 501, the sliding rail 502 is fixedly connected to the upper surface of the rim of the mounting shell 2, the support plate 501 slides on the surface of the sliding rail 502, the side of the support plate 501 away from the sliding rail 502 slides on the surface of the mounting shell 2, a plurality of through slots 503 for the clamping blocks 4 to pass through are formed in the surface of the support plate 501, one end of the support plate 501 is fixedly connected to two first springs 6 for resetting the support plate 501, the other ends of the two first springs 6 are fixed to the upper surface of the rim of the mounting shell 2.

[0026] It can be understood that the battery pack 1 is mounted into the mounting shell 2, the plurality of clamping blocks 4 are inserted into the grooves 3 through the plurality of through slots 503, the first springs 6 push the support plate 501 to slide on the surface of the sliding rail 502, so that the through slots 503 are staggered with the clamping blocks 4, the lower surfaces of the clamping blocks 4 are supported on the upper surface of the support plate 501, thereby facilitating the quick mounting and fixing of the battery pack 1, the clamping blocks 4 are triangular and the sharp corners face upward, thereby facilitating the insertion of the clamping blocks 4 into the grooves 3 when the battery pack 1 is mounted.

[0027] Specifically, the support plate 501 is provided with a pressing assembly 7 away from one end of the first spring 6, the pressing assembly 7 comprises an inclined block 701 fixed at one end of the support plate 501 away from the first spring 6 and a pressing block 702 sliding at the edge of the mounting shell 2, the inclined surface of the surface of the inclined block 701 is inclined upward from the side close to the support plate 501, the surface of the pressing block 702 is provided with an inclined surface matched with the inclined block 701, the top of the pressing block 702 is fixedly connected with a second spring 703, the lower end of the second spring 703 is fixedly connected to the upper surface of the edge of the mounting shell 2, the second spring 703 is a tension spring, the surface of the pressing block 702 above the edge of the mounting shell 2 is provided with a limiting ring 704, and the lower surface of the pressing block 702 is fixedly connected with a limiting plate 705.

[0028] It can be understood that by pushing the pressing block 702 upward, the inclined block 701 is pushed away from the pressing block 702 under the cooperation of the inclined surface, so that the inclined block 701 drives the support plate 501 to slide, the through slot 503 is corresponded with the clamping block 4, so that the clamping block 4 falls down through the through slot 503, thereby facilitating the battery pack 1 to be taken out of the mounting shell 2. By arranging the limiting ring 704 and the limiting plate 705, the sliding height of the pressing block 702 is limited. By arranging a plurality of pressing assemblies 7, a plurality of support plates 501 can be controlled to slide individually, and one side of the battery pack 1 can be disassembled individually. When an unexpected foreign object accidentally pushes the pressing block 702 and causes the battery pack 1 to fall off, a plurality of pressing assemblies 7 are used to disassemble each side of the battery pack 1 individually, and the pressing block 702 is pressed during the disassembly process. Therefore, the risk of accidental falling of the battery pack 1 can be greatly reduced.

[0029] Specifically, the upper surface of the support plate 501 is fixedly connected with a first positioning sensor 8, and the surface of the sliding rail 502 is fixedly connected with a second positioning sensor 9 matched with the first positioning sensor 8. Both the first positioning sensor 8 and the second positioning sensor 9 are infrared positioning sensors.

[0030] It can be understood that by arranging the first positioning sensor 8 and the second positioning sensor 9, the sliding position of the support plate 501 can be detected, so as to determine whether the support plate 501 supports the clamping block 4, thereby avoiding the phenomenon that the battery pack 1 is not fixed stably due to the fact that the support plate 501 is not slid in place.

[0031] Specifically, the inner wall of the mounting shell 2 is fixedly connected with a rubber pad 10 at the top.

[0032] It can be understood that by setting the rubber pad 10, the rubber pad 10 continuously generates a downward pushing force on the battery pack 1 when the battery pack 1 is installed, so that the clamping block 4 on the surface of the battery pack 1 is always attached to the surface of the support plate 501, preventing the battery pack 1 from loosening.

[0033] Specifically, the upper surface of the inclined block 701 is provided with an elongated hole, and the top block 702 is fixedly connected with a pull rod near one side of the inclined block 701, and the pull rod is L-shaped,

[0034] It can be understood that when the first spring 6 pushes the support plate 501 and the inclined block 701 into place, that is, after the battery pack 1 is installed and fixed, the pull rod is inserted into the elongated hole, so that the position of the inclined block 701 is limited by the pull rod, thereby avoiding the inclined block 701 from moving away from the top block 702 due to vibration during vehicle driving, causing the clamping block 4 to accidentally correspond to the through groove 503, and causing the battery pack 1 to loosen or even fall off. Since the movement trajectory of the inclined block 701 and the top block 702 is that the inclined block 701 moves upward at the same time, it will push the inclined block 701 away from the top block 702; therefore, by setting the elongated hole, the pull rod has a certain moving space in the elongated hole when the top block 702 and the inclined block 701 move synchronously, so that the top block 702 can drive the pull rod to rise and leave the elongated hole, thereby allowing the inclined block 701 to slide a long distance, and avoiding movement interference between the top block 702 and the inclined block 701, and the moving space of the pull rod is smaller than the distance between the clamping block 4 and the through groove 503.

[0035] The utility model discloses a plurality of top blocks 702 are pressed simultaneously, under the cooperation of the inclined plane, push away the inclined block 701 from the top block 702, make the inclined block 701 drive the support plate 501 slide, and the through groove 503 is corresponding with the position of recess 3, and the battery pack 1 is installed in the installation shell 2 using the lifting equipment, and the battery pack 1 is extruded to the rubber pad 10, and the plurality of clamping blocks 4 are inserted in the inner wall of the plurality of recess 3 through the through groove 503, and the height of the lower surface of clamping block 4 is higher than the height of the upper surface of support plate 501, then the pressing of the plurality of top blocks 702 is released, under the action of first spring 6, push the support plate 501 to slide on the surface of slide rail 502, thereby make the through groove 503 stagger with clamping block 4, make the lower surface of clamping block 4 support on the upper surface of support plate 501, under the action of rubber pad 10, make rubber pad 10 continuously generate downward thrust to the battery pack 1, make clamping block 4 on the surface of battery pack 1 adhere on the surface of support plate 501 at all times, prevent the battery pack 1 from loosening, thereby facilitate the installation and fixation of battery pack 1, first positioning sensor 8 and second positioning sensor 9, thereby can detect the sliding position of support plate 501, judge whether support plate 501 supports clamping block 4, avoid the phenomenon of unstable fixation to battery pack 1 due to the fact that support plate 501 does not slide in place, when needing to disassemble battery pack 1, press the plurality of top blocks 702 again, make the position of through groove 503 correspond with clamping block 4, thereby make clamping block 4 fall down through the through groove 503, facilitate the battery pack 1 to be taken out from the installation shell 2.
