DETAILED DESCRIPTION

[0024] The directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention of the utility model.

[0025] like Figure 1-4 As shown, a battery pulling structure of an energy storage cabinet includes a battery cabinet 1 and a support assembly 5. The battery cabinet 1 is provided with a drawer 2 for holding batteries, so that the batteries are easy to store and access. The support assembly 5 includes a support seat 51, a support plate 52 and a pulley 53. The pulley 53 is installed at the rear bottom of the drawer 2, and the drawer 2 can slide in the battery cabinet 1 through the pulley 53. The support seat 51 is fixedly connected to both sides of the battery cabinet 1, and the support plate 52 is fixedly connected to the upper side of the support seat 51. The support plate 52 includes a straight portion 521, a transition portion 522 and a limit portion 523 connected in sequence from front to back, so that the drawer 2 can smoothly transition during the sliding process to avoid sudden tilting or jamming. The straight portion 521 is horizontally arranged to provide stable support, and the transition portion 522 is tilted to play a guiding role, and the tilt degree of the transition portion 522 is less than the tilt degree of the limit portion 523, ensuring that the drawer 2 remains stable when it is about to be pulled out. The upper opening of the draw box 2 is provided to facilitate the insertion and removal of batteries, and the draw box 2 includes a left side plate 21, a right side plate 22, a rear side plate 23, a front side plate 24 and a bottom plate 25. In the front-to-back direction, the distance from the top of the limit portion 523 to the battery cabinet 1 is greater than the distance from the front end of the pulley 53 to the battery cabinet 1; the distance from the bottom end of the limit portion 523 to the upper end surface of the straight portion 521 is greater than the distance from the axis of the pulley 53 to the bottom plate 25 of the draw box 2, so that when the pulley 53 falls or just falls, the bottom plate 25 abuts against the straight portion 521, and at this time the pulley 53 receives an oblique backward force, so the pulley 53 can only be pulled to the limit portion 523 under the action of an external force, so as to achieve the limit of the draw box 2; at the same time, the distance from the bottom end of the limit portion 523 to the upper end surface of the straight portion 521 is less than the distance from the bottom end of the pulley 53 to the bottom plate 25, so as to prevent the stability of the draw box 2 from being further enhanced during the pulling process.

[0026] Specifically, a handle 3 is fixedly connected to the front side plate 24 to facilitate the user to operate the box 2 .

[0027] Specifically, the left side plate 21, the right side plate 22, the rear side plate 23 and the front side plate 24 are all concave-shaped. This design can reduce the material usage of the pull box 2 without affecting its strength and stability, and can accommodate the protruding part of the battery shell.

[0028] Specifically, the height of the front side plate 24 and the rear side plate 23 is less than half of the height of the left side plate 21 or the right side plate 22 , so that the pull box 2 is more lightweight while maintaining sufficient structural strength.

[0029] Specifically, the front side plate 24 is formed into a concave shape by setting a clearance groove in the middle, and the two ends of the handle 3 are arranged outside the clearance groove. The handle 3 is arranged across the clearance groove, which not only optimizes the layout of the handle 3 but also improves the overall structural strength of the front side plate 24.

[0030] Specifically, the bottom front side of the bottom plate 25 is fixedly connected to a limit plate. In the horizontal direction, the horizontal distance from the limit plate to the pulley 53 is greater than the length of the support plate 52, ensuring that the bottom plate 25 can fall on the support plate 52 and preventing the pull box 2 from tilting excessively or sliding out during the pulling process.

[0031] Specifically, the battery cabinet 1 has an electrical box 4 fixedly connected to the rear side, in which is provided an installation cavity 42 for placing electrical components, and the electrical box 4 has a buffer pad 41 fixedly connected to the front side for abutting the rear side plate 23, which can reduce the impact and friction of the pulling box 2 on the electrical box 4 during the sliding process.

[0032] Specifically, the cross section of the support base 51 is in the shape of a gate. This design not only ensures the strength of the support base 51 , but also reduces its weight, and at the same time facilitates connection and fixation with the battery cabinet 1 .

[0033] Working principle: When the battery needs to be taken out, the user only needs to open the cabinet door, grab the handle 3 on the front side plate 24 of the drawer 2, and pull the drawer 2 outward. Under the action of the pulley 53, the drawer 2 slides smoothly and obliquely upward along the support plate 52 until it is fully pulled out. At this time, the user can take out the required batteries from the drawer 2. If the drawer 2 needs to be used again, the user can push it back into the battery cabinet 1 until the drawer 2 is fully pushed in and the pulley 53 contacts the support plate 52 and remains stable. During the whole process, due to the special design of the support plate 52 and the structural optimization of the drawer 2, the convenience and stability of the operation are ensured, while the impact and friction on the battery and the electrical box 4 are reduced, providing a better quality use experience, especially suitable for battery cabinets 1 with lower heights, which can reduce the fatigue of the user's waist.
