A third through-hole 205 and a fourth through-hole 206 are provided on the charger bracket 201. The middle part of the charging space 16 is connected to the energy storage space 301 via the first through-hole 13 and the third through-hole 205, and the first through-hole 13 and the third through-hole 205 are at the same height, position, and size. The side of the electrical space 16 is connected to the energy storage space 301 via the second through hole 14 and the fourth through hole 206, and the second through hole 14 and the fourth through hole 206 are in the same position; the cabinet 101 is provided with a cabinet horizontal baffle 106, which has an upper protruding threshold 107. The charging box 103 is placed on the cabinet horizontal baffle 106, which is a flat and long strip that runs through the entire cabinet 101, providing good support for the charging box 103. The bottom of the charging box 103 has a groove to fit the upper protruding threshold 107; the charging box 103 has an opening 10 Each charging case 103 has two handles 108 with outward threaded engagement in four directions, allowing users to easily pull the charging case 103 out of the charging cabinet and carry it to the desired location for use. All handles 108 are U-shaped. The U-shaped handle, with its unique curved design, combines practicality and aesthetics. Its ergonomic U-shaped structure naturally conforms to the curvature of the palm, providing a stable grip, while reducing hand fatigue by distributing pressure points. It is especially suitable for prolonged lifting of heavy objects or frequent operation. Furthermore, the U... The structure features uniform stress distribution, strong load-bearing capacity, and extended service life. The charging box 103 has an inwardly protruding rectangular slot 302 on one side of the energy storage space 301 to restrict the position of the battery within the energy storage space 301, preventing accidental impacts when the battery is removed or moved. The entire charging cabinet is made of stainless steel, an alloy material formed by adding elements such as chromium and nickel. Stainless steel offers several advantages: its dense passivation film formed by chromium provides excellent corrosion resistance, effectively preventing rust in harsh environments such as humidity, acids, alkalis, and salt spray; it also possesses high strength and toughness, resulting in a long service life and low maintenance costs, eliminating the need for frequent anti-corrosion treatments; its smooth and clean surface, free of metal ion precipitation, requires minimal maintenance, and is environmentally friendly and recyclable.

[0029] like Figure 3-4 As shown: The charging box 103 has a cabinet door 109 on the front side, which is embedded in the surface of the charging box 103. The cabinet door 109 has an observation window 110, which allows users to easily observe whether the charging box 103 is in use, providing convenience for users. The cabinet door 109 is equipped with a rotary lock 111, and the charging box 103 has a locking stop 112 that matches the rotary lock 111. By pressing and turning the rotary lock 111, the locking tongue of the rotary lock 111 can be turned away from the locking stop 112, thereby opening the cabinet door 109. The rotary lock 111 is efficient and convenient. Its rotary operation design is simple and intuitive, and it is easy and effortless to use. Users only need to press and turn the rotary knob to quickly open and close it without complicated operations. The structure is compact and the size is small, saving cabinet space. In addition, the mechanical structure of the rotary lock 111 is stable and reliable, highly durable, not easy to wear after long-term use, and has low maintenance costs.

[0030] like Figure 5-6 As shown: The top cover of the charging space 16 is a fixed top cover 207, which is fixedly connected to the vertical plate 12 by welding. The fixed top cover 207 has a lower protruding threshold 114 on the inner side 113 of the cabinet door. The top of the charging box 103 has a groove to fit the lower protruding threshold 114. The horizontal baffle 106 of the cabinet also has an upper protruding threshold 107 that fits the groove at the bottom of the charging box 103. The lower protruding threshold 114 and the upper protruding threshold 107 together lock the upper and lower parts of the cabinet door 109. The top cover of the energy storage space 301 is a movable top cover 303. The movable top cover 303 is movably connected to the fixed top cover 207 via a hinge 15 and screws. The movable top cover 303 is provided with a rectangular opening hole 304. The top of the energy storage space 301 is also provided with a flat opening notch 305 opposite to the rectangular opening hole 304, providing two different ways to open the energy storage space 301. Either you can insert your finger into the rectangular opening hole 304 to hook it and lift the movable top cover 303 upwards, or you can insert your finger into the flat opening notch 305 to push the movable top cover 303 upwards. The flexible and varied opening methods provide convenience for use.

[0031] like Figure 7-8 As shown: Rectangular side wings 208 extend from both sides of the charger base 202. The charger base 202 is fixed to the charger bracket 201 by side wing screws 209 and side wings 208. Front baffles 210 are provided on both sides of the front end of the charger base 202. The front baffles 210 are plate-shaped and stand upright at the front end of the charger base 202, which not only allows for better placement inside the charger base 202, but also restricts the position of items inside the charger base 202, thereby protecting the items inside and preventing damage or adverse effects to the items placed inside the charger base 202 when the charging box 103 is removed. The charger top plate 204 is an L-shaped right-angle fixing bracket, which is fixed to the top of the charger bracket 201 by fixing screws 211.

[0032] like Figure 9 As shown: There are two horizontal sliding doors 115 on the back of the cabinet 101. The sliding doors 115 can be easily opened to allow heat dissipation and avoid the adverse effects of excessive temperature. Inside the sliding doors 115, there is a cabinet support plate 116 that connects with the cabinet horizontal baffle 106. This not only provides support for the cabinet horizontal baffle 106, but also provides support for the entire cabinet 101.

[0033] In summary, this utility model has multiple charging boxes that accommodate independent charging spaces, and each charging box can be pulled out of the cabinet for individual use, improving the flexibility and portability of use.
