Several weight-reducing holes 15 are provided on the base frame 11 and the upright frame 12 respectively to ensure strength while avoiding overweight.

[0022] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the battery box body 2 is equipped with a battery mounting mechanism 3. The battery mounting mechanism 3 includes a pair of parallel slide rails 31, two slide rails 32, a battery mounting bracket 33, two pressure plates 34, and four T-shaped pull rods 35. The pair of parallel slide rails 31 are longitudinally welded and fixed to the bottom of the battery box body 2, and the inner ends of the slide rails 31 are respectively welded with limiting pins 36. The slide rails 32 are made of polytetrafluoroethylene (PTFE) sheets, such as... Figure 3As shown, a pre-embedded iron 37 is welded to the bottom of the slide rail 31. Two slide rails 32 are fixedly supported on the slide rail 31 by multiple countersunk screws 38. The surface of the polytetrafluoroethylene plate is smooth, which ensures that the slide plate 30 at the bottom of the battery mounting bracket 33 can be smoothly pulled out after the battery pack is installed, meeting the needs of daily maintenance. The battery mounting bracket 33 is trough-shaped and can be appropriately enlarged to accommodate the installation of different models of battery packs. Four hook plates 39 are symmetrically provided on both sides of the battery mounting bracket 33. Slide plates 30 are welded to the bottom sides of the battery mounting bracket 33, and the slide plates 30 are slidably supported on the two slide rails 32. The inner ends of the slide plates 30 and the slide rails 32 are provided with U-shaped grooves 10. The limiting pins 36 at the inner end of the slide rail 31 are respectively engaged in the U-shaped grooves 10 at the inner end of the slide plate 30. The outer ends of the slide plates 30 are fixed to the outer ends of the slide rail 31 by wing screws 20, thus reliably fixing the battery mounting bracket 33. The battery pack 40 is placed side-by-side inside the battery mounting bracket 33. Two pressure plates 34 press horizontally onto the top of the battery pack 40. A sponge rubber sheet 50 is attached to the bottom of the pressure plates 34 to effectively cushion and absorb shock, protecting the surface of the battery pack 40. The lower ends (T-shaped ends) of the four T-shaped pull rods 35 are hooked onto corresponding hook plates 39. The upper ends of the four T-shaped pull rods 35 pass through both ends of the pressure plates 34 and are locked in place with wing nuts. Through these measures, the battery pack 40 can be securely fixed inside the battery mounting bracket 33. The upper ends of the T-shaped pull rods 35 are threaded to ensure adjustable height.

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the battery box housing 2 includes an outer shell 21, an inner frame 22, and a door 23.

The door 23 is a side-opening type, which allows maintenance personnel to get closer to the housing than a bottom-opening door. The side-opening door is also easier to operate, and the entire system is less prone to deformation after long-term use. Figure 5 As shown, D-shaped sealing strips 25 are affixed to the contact points between the door 23 and the outer shell 21 to ensure airtightness and effectively prevent water and dust. A π-shaped component is welded to the inside of the door 23 to prevent deformation. A rainproof eave 26 is provided on the top front side of the outer shell 21 for effective rain protection. Several drainage holes 27 are provided on the bottom of the outer shell 21 to ensure drainage in case of accidental water ingress. Water-retaining flanges 28 are bent out on all four sides of the front side of the outer shell 21. The back of the outer shell 21 is open and has a maintenance plate 29. The maintenance plate 29 is fixed to the back of the outer shell 21 with fasteners. It can be removed for maintenance when necessary. The maintenance plate 29 has wiring holes 60 for easy cable routing.

[0024] When replacing the battery pack 40 during routine maintenance, first use the key to open the door 23 and unscrew the wing screw 20 at the outer end of the slide plate 30. Then, holding the battery pack 40, gently pull it out of the battery box 2 along the slide rail 32. After pulling it out, use a wooden brace to vertically support the bottom outer end of the battery mounting bracket 33. Unscrew the wing nut at the upper end of the T-shaped pull rod 35 and remove the pressure plate 34. The battery pack 40 can then be replaced. After replacement, place the battery pack 40 back into the battery mounting bracket 33 and press it down using the pressure plate 34 and the T-shaped pull rod 35. Slowly push it into the battery box 2 until the limiting pin 26 at the inner end of the slide rail 31 engages with the U-shaped groove 10 at the inner end of the slide plate 30. At this point, secure the outer end of the slide plate 30 with the wing screw 20, close and lock the door 23, and the maintenance replacement is complete. If necessary, the battery pack 40 along with the battery mounting bracket 33 can also be removed, hoisted to a designated position, and then removed for replacement.

[0025] In addition to the above embodiments, the present invention may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
