[0037] like Figure 1As shown, the power supply housing 1 assembly of an embodiment of the utility model includes a housing 1 and a wheel assembly 2, wherein the housing 1 can be generally square, and the material of the housing 1 can be metal, plastic, etc. The lower part of the housing 1 is provided with a mounting portion 11, for example, Figure 1 As shown, the mounting portion 11 can be integrally formed on the rear bottom side of the housing 1 , and the mounting portion 11 can be a hole-shaped structure, an axis-shaped structure, etc.

[0038] The wheel assembly 2 includes a wheel body 21 and a wheel axle 22. The wheel body 21 is rotatably mounted on the outer peripheral side of the wheel axle 22, and the wheel axle 22 is detachably mounted on the mounting portion 11. Figure 2 As shown, the axle 22 can be located on a circular axis and can extend in the left-right direction. The end of the axle 22 can be directly and detachably fixed on the mounting portion 11. The specific fixing method can be snap fixing, fastener fixing, etc. The wheel body 21 can be assembled on the outer peripheral side of the axle 22 and can rotate freely relative to the axle 22.

[0039] like Figure 1 and Figure 2 As shown, two mounting portions 11 may be provided on the shell 1, and the two mounting portions 11 may be respectively provided on the left and right sides of the shell 1. Two wheel assemblies 2 may also be provided, and the two wheel assemblies 2 may be assembled at the two mounting portions 11 one by one.

[0040] The power housing 1 assembly of the embodiment of the utility model is provided with a wheel assembly 2 at the bottom of the power housing 1 assembly, which facilitates the movement of the whole. Secondly, when it is not necessary to move, the wheel assembly 2 can also be removed, thereby avoiding the situation where the wheel assembly 2 protrudes from the outside of the housing 1 and is not easy to be placed in a small space, thereby improving the convenience and flexibility of use.

[0041] In some embodiments, the mounting portion 11 is disposed at the lower side of the housing 1. Figure 1 As shown, the mounting portion 11 can be provided at the lower part of the rear side of the housing 1, and the mounting portion 11 can be located on the left or right side of the housing 1. Thus, when moving, the housing 1 can be arranged tilted with the wheel assembly 2 as a fulcrum, thereby avoiding the situation where the housing 1 is easily scratched against the ground when the wheel assembly 2 is provided at the middle of the bottom wall, etc., and improving the convenience of movement.

[0042] In some embodiments, the shell 1 includes a bottom shell 12 and a top cover 13. The bottom shell 12 is integrally formed and has an inner cavity for placing the battery module.

The top cover 13 is detachably sealed at the opening, and the mounting portion 11 is arranged at the lower side of the side of the bottom shell 12.

[0043] For example, Figure 2As shown, the material of the bottom shell 12 can be metal, and the bottom shell 12 can be integrally formed by casting, thereby ensuring waterproof sealing, and secondly making the housing 1 have better heat dissipation performance.

[0044] The material of the top cover 13 can be plastic. When the battery module is placed in the bottom shell 12, the top cover 13 can be fixed to the top side of the bottom shell 12 by fasteners such as screws, thereby achieving sealing of the shell 1 and further isolating and protecting the battery module.

[0045] The mounting portion 11 may be integrally formed on the rear bottom of the bottom shell 12 . When the bottom shell 12 is made of metal, the mounting portion 11 may also be integrally formed on the bottom shell 12 by casting or the like.

[0046] In some embodiments, a plurality of foot pads 4 are provided on the bottom side of the shell 1 , and the plurality of foot pads 4 are arranged at intervals along the circumference of the bottom shell 12 , and the end faces of the foot pads 4 that are used to contact the ground are flush with the lowest point on the outer peripheral contour of the wheel body 21 .

[0047] For example, Figure 3 As shown, the material of the foot pad 4 can be rubber, silicone, plastic, etc. The foot pad 4 can be installed on the bottom of the bottom shell 12 by fasteners such as screws. Four foot pads 4 can be provided, and the four foot pads 4 can be respectively arranged at the four corners of the bottom of the bottom shell 12.

[0048] like Figure 3 As shown, the lowest point of the wheel body 21 is the moving point, and the lowest point is also the point at the lowest position in the wheel body 21, that is, Figure 3 Position point A in the middle. Position point A is substantially flush with the bottom end surface of the foot pad 4. Thus, the wheel body 21 and the plurality of foot pads 4 can simultaneously support the housing 1, thereby enhancing the structural stability of the mobile power supply when placed.

[0049] In some embodiments, Figure 2 As shown, there are two mounting parts 11 and two wheel assemblies 2, the two mounting parts 11 are arranged opposite to each other, and the two mounting parts 11 can be integrally formed at the rear bottom of the bottom shell 12, and the two mounting parts 11 can be arranged opposite to each other along the rear bottom edge of the bottom shell 12. The two wheel assemblies 2 are assembled at the two mounting parts 11 in a one-to-one correspondence, and the bottom shell 12 is located between the two wheel assemblies 2, thereby increasing the support range of the two wheel assemblies 2 in the left and right directions, thereby enhancing the support stability.

Taking the right wheel assembly 2 as an example, the first hub cover 24 of the right wheel assembly 2 can be arranged on the right side of the wheel body 21. The radial dimension of the first hub cover 24 can be larger than the outer diameter of the above-mentioned bearing 23, but smaller than the outer diameter of the wheel body 21. The first hub cover 24 can shield the outer side of the wheel body 21 and the bearing 23, thereby improving the protection effect.

[0053] In some embodiments, the wheel assembly 2 further includes a second hub cover 25 , which is sleeved on the wheel axle 22 and fixed to the side of the wheel body 21 facing the housing 1 , and is used to cover the shielding bearing 23 and part of the wheel body 21 .

[0059] For example, Figure 4 As shown, the first annular groove 213 can be provided on the right side of the wheel hub 211, and the first annular groove 213 is annular and can surround the outer peripheral side of the bearing 23. The first flange 242 can be annular and can be integrally formed with the first hub cover 24, and the first flange 242 can extend along the outer peripheral edge of the first hub cover 24 to form a circle.

[0060] During assembly, the first flange 242 can be embedded in the first annular groove 213 , and the structural compactness and stability of the assembly of the first hub cover 24 and the wheel hub 211 can be enhanced by the blocking and limiting of the first flange 242 and the groove wall of the first annular groove 213 .

[0061] In some embodiments, a second annular groove 212 is provided on the other side of the wheel hub 211 , and the second annular groove 212 surrounds the outer peripheral side of the bearing 23 . A second flange 252 is provided on the outer peripheral edge of the second hub cover 25 , and the second flange 252 is annular and embedded in the second annular groove 212 .

[0062] For example, Figure 4 As shown, the second annular groove 212 can be provided on the left side of the wheel hub 211, and the second annular groove 212 is annular and can surround the outer peripheral side of the bearing 23. The second flange 252 can be annular and can be integrally formed with the second hub cover 25, and the second flange 252 can extend along the outer peripheral edge of the second hub cover 25 to form a circle.

[0063] During assembly, the second flange 252 can be embedded in the second annular groove 212 , and the stopping and limiting of the second flange 252 and the groove wall of the second annular groove 212 can enhance the structural compactness and stability of the assembly of the second hub cover 25 and the wheel hub 211 .

[0064] In some embodiments, the mounting portion 11 is a mounting hole 111, and the axle 22 is threadedly assembled in the mounting hole 111. Figure 5 As shown, the mounting hole 111 may be a threaded hole, and the mounting hole 111 extends in the left-right direction.
