[0043] like Figure 4 As shown, during the use of the stabilizing mechanism 15, when the movable tray 7 is not moved, the stabilizing mechanism 15 is in the initial state. At this time, the stabilizing platform 44 is located inside the top rail 40, the driving plate 48 is located inside the bottom rail 41, and the moving wheels 52 contact the top rail 40 and the bottom rail 41 respectively to reduce friction, and the limiting edge 51 has a limiting effect on the stabilizing platform 44 and the driving plate 48. When the mobile tray 7 needs to be moved, the mobile tray 7 is pulled by the handle, and the mobile tray 7 drives the driving plate 48 to move in the bottom rail 41 through the connecting plate 38, and drives the driving gear 50 to rotate through the driving rack 49, and the driving gear 50 moves along the upper fixed tooth plate 42. As the driving gear 50 moves, the pressure stabilizing platform 44 is driven to move inside the top rail 40, and the driven gear 46 between the pressure stabilizing rack 45 and the lower fixed tooth plate 43 starts to mesh and rotate, and the driven gear 46 moves along the lower fixed tooth plate 43.

[0045] like Figure 5-6 As shown, during the use of the locking mechanism 14, before being locked, the bent rod 28 is hinged to the support seat 27 through the first hinge shaft 31 and can rotate freely. The lock bar 30 is movably arranged inside the limit box 29, and one end of the lock bar 30 can extend outside the limit box 29. The limit box 29 is used to ensure that the lock bar 30 moves along the limit box 29. The protrusion 32 is fixedly arranged in the middle of the bent rod 28. The connecting shaft 33 connects the protrusion 32 and the lock bar 30, and both are hinged through the second hinge shaft 34. Hold the handle 35 and rotate the bent rod 28 in the direction close to the front side plate 25. The rotation of the bent rod 28 drives the protrusion 32 to move, and then drives the lock bar 30 to move inside the limit box 29 through the connecting shaft 33 and the second hinge shaft 34. When the bent rod 28 rotates to a certain angle, one end of the lock bar 30 will extend outside the limit box 29 and snap into the corresponding locking position of the energy storage bin 3. At this time, the mobile tray 7 is locked in the energy storage bin 3 and cannot move freely. The handle 35 is placed inside the snap ring 36 through the opening outside the limit box 29. The design of the snap ring 36 can prevent the handle 35 from rotating by itself without force, thereby ensuring the stability of the locking mechanism 14. When it is necessary to unlock, hold the handle 35 again, move the handle 35 out of the snap ring 36, and rotate the bent rod 28 away from the front side plate 25. The rotation of the bent rod 28 also drives the protrusion 32 to move, and then drives the lock bar 30 to move inside the limit box 29 through the connecting shaft 33 and the second hinge shaft 34. When the bent rod 28 rotates to a certain angle, one end of the lock bar 30 will be pulled out of the locking position of the energy storage bin 3. At this time, the mobile tray 7 is unlocked and can move freely.

[0046] The implementation principle of the present invention is: When the present invention is installed and used, the design of the hanging plate 53 and the hanging ring 54 on the top of the cabinet 1 makes it easy to carry and transport with lifting tools.

When the battery module 8 is installed and subsequently repaired, the mobile tray 7 can be moved out by the stabilizing mechanism 15. First, the locking mechanism 14 needs to be unlocked, the handle 35 is moved out from the inside of the clamp ring 36, and the bent rod 28 is rotated in a direction away from the front side plate 25. The rotation of the bent rod 28 also drives the protrusion 32 to move, and then drives the lock bar 30 to move inside the limit box 29 through the connecting shaft 33 and the second hinge shaft 34. When the bent rod 28 rotates to a certain angle, one end of the lock bar 30 will be pulled out from the locking position of the energy storage compartment 3. At this time, the mobile tray 7 is unlocked and can move freely. The mobile tray 7 is moved by the handle 26. During the movement, the stabilizing mechanism 15 ensures the stability of the mobile tray 7. The mobile tray 7 is pulled by the handle 26. The mobile tray 7 drives the driving plate 48 to move in the bottom rail 41 through the connecting plate 38. At the same time, the driving gear 50 is driven to rotate by the driving rack 49. At the same time, the driving gear 50 moves along the upper fixed tooth plate 42. With the movement of the driving gear 50, the voltage stabilizing platform 44 is driven to move inside the top rail 40. At the same time, the driven gear 46 between the voltage stabilizing rack 45 and the lower fixed tooth plate 43 begins to mesh and rotate. At the same time, the driven gear 46 moves along the lower fixed tooth plate 43. The rotation of the driven gear 46 enables the voltage stabilizing platform 44 to adjust its position smoothly.
