DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1 - Figure 5 A built-in storage cabinet for new energy vehicles includes a box body 1, a mounting assembly is connected to the top of the box body 1, a number of partitions 2 are equidistantly connected to the inner wall of the box body 1, and the partitions 2 divide the interior of the box body 1 into a number of mounting cavities 101, and a mounting port 102 communicating with the number of mounting cavities 101 is opened through one side of the box body 1. Battery packs 3 are connected to the several mounting cavities 101, and the side of the several battery packs 3 away from the mounting port 102 is connected to the connecting assembly, and the side of the box body 1 close to the mounting port 102 is connected to the sealing plate 4.

[0026] like Figure 1 - Figure 5 As shown, the structure of a built-in storage cabinet for a new energy vehicle in the present invention is similar to that of an existing built-in storage cabinet for a new energy vehicle, such as a new energy vehicle integrated battery box disclosed in the patent publication number CN209249643U. The main improvement of the present invention is that the battery pack 3 that needs to be replaced can be disassembled, replaced and installed without disassembling the entire box 1. Figures 1 to 5 As shown, when the built-in storage cabinet for new energy vehicles in the utility model is in use, multiple battery packs 3 are respectively installed in the installation cavity 101 formed by multiple partitions 2 in the box body 1, and the electrical energy of the multiple battery packs 3 is interconnected through the connecting components. Subsequently, the multiple installation ports 102 on the side of the box body 1 are blocked with a sealing plate 4. When the efficiency of one of the battery packs 3 or part of the battery packs 3 is reduced, affecting normal use, it is only necessary to remove the sealing plate 4 and pull the battery pack 3 to be replaced out of the corresponding installation cavity 101 through the installation port 102, and then reinstall the new battery pack 3, thereby reducing the replacement cost of the internal battery of the new energy vehicle. During the replacement process, there is no need to disassemble the entire box body 1, thereby improving the replacement efficiency of the battery pack 3.

[0027] like Figure 1 - Figure 3 As shown, the mounting assembly includes a mounting ring 5 and two symmetrically arranged mounting plates 6. The mounting ring 5 is fixedly connected to the top edge of the housing 1, and the two mounting plates 6 are fixedly connected to the outer walls of the mounting ring 5 on both sides. Both mounting plates 6 are provided with a plurality of mounting holes 601. The entire housing 1 can be mounted to the mounting position on the bottom of the vehicle using the mounting plates 6 on both sides of the top mounting ring 5. Screws or other fasteners are used to secure the housing 1 to the vehicle battery mounting position through the mounting holes 601.

[0028] like Figure 1 - Figure 5 As shown, the connection assembly includes a circuit board 7 and a plurality of positive and negative plugs 8. The circuit board 7 is slidably connected to the inner wall of the housing 1 on the side away from the mounting opening 102. The side of the circuit board 7 close to the mounting cavities 101 is provided with a plurality of positive and negative connection holes 701. The plurality of positive and negative connection holes 701 are matched with the plurality of positive and negative plugs 8. When the battery pack 3 is inserted into the mounting cavity 101 through the mounting opening 102, the positive and negative plugs 8 at the ends of the battery pack 3 are inserted into the corresponding positive and negative connection holes 701 on the circuit board 7, thereby realizing a quick connection and power-up between the battery pack 3 and the circuit board 7. When the battery pack 3 is installed in the mounting cavity 101, the positive and negative positions of the positive and negative plugs 8 need to be aligned with the positive and negative connection holes 701 on the circuit board 7 to avoid reversing the positive and negative poles.

[0029] like Figure 1 - Figure 5As shown, baffles 9 are fixedly connected to both sides of the end of the mounting cavity 101 away from the mounting opening 102. The end of the battery pack 3 away from the mounting opening 102 abuts against the two baffles 9, and the positive and negative plugs 8 pass through the gap between the two baffles 9 and connect to the positive and negative connection holes 701. When the battery pack 3 moves toward the circuit board 7 and the positive and negative plugs 8 are inserted into the positive and negative connection holes 701, the baffles 9 can block the battery pack 3, thereby preventing the positive and negative plugs 8 from continuing to slide inward after being inserted into the positive and negative connection holes 701, causing the positive and negative plugs 8 to collide with the positive and negative connection holes 701 and be damaged.

[0030] like Figure 1 - Figure 3 As shown, the side walls of the plurality of partitions 2 are fixedly connected to the inner wall of the box body 1. The partitions 2 are fixed to the box body 1 to prevent the battery pack 3 from shaking when the car moves after being installed in the installation cavity 101, thereby improving the stability of the battery pack 3 in the box body 1.

[0031] like Figure 2 As shown, a pull ring 10 is fixedly connected to one side of the battery pack 3 near the installation opening 102. The pull ring 10 can be used to more conveniently pull the battery pack 3 out of the installation opening 102 and the installation cavity 101, making it easier to replace the battery pack 3.

[0032] like Figure 4 As shown, two symmetrical extrusion blocks 11 are provided within the mounting opening 102. The two extrusion blocks 11 are located on either side of the pull ring 10, with one side of each extrusion block 11 abutting against the battery pack 3 and the other side fixedly connected to the sealing plate 4. When the battery pack 3 is installed in the mounting cavity 101 and the multiple mounting openings 102 are sealed with the sealing plate 4, the corresponding two extrusion blocks 11 squeeze the battery pack 3 into the mounting cavity 101, and cooperate with the baffle 9 at the other end of the battery pack 3 to clamp the battery pack 3 within the mounting cavity 101, thereby preventing the battery pack 3 from shaking.

[0033] like Figure 1 - Figure 5 As shown, the sealing plate 4 is fixedly connected to the side of the box body 1 near the mounting opening 102 by a plurality of bolts. The sealing plate 4 is fixed to the side of the box body 1 using a plurality of bolts to prevent the connection between the sealing plate 4 and the box body 1 from loosening during the driving process of the car.

[0034] like Figure 2 - Figure 5As shown, a plurality of limiting grooves 301 are formed on both sides of the battery pack 3, and a plurality of limiting bars 12 are fixedly connected to the inner walls of both sides of the installation cavity 101. The limiting bars 12 are slidably connected to the limiting grooves 301. When the battery pack 3 is installed in the installation cavity 101, the connection between the plurality of limiting grooves 301 and the limiting bars 12 inside the installation cavity 101 prevents the battery pack 3 from rocking up and down in the installation cavity 101. In combination with the baffles 9 and the extrusion blocks 11 at both ends, the battery pack 3 is completely fixed in the installation cavity 101, thereby improving the stability of the battery pack 3 in the box 1 during driving.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
