[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1 to 4As shown, this is the first embodiment of the utility model, which provides a pull-out lithium battery energy storage device, including a protective shell 1, a pull-out component 2 disposed in the inner cavity of the protective shell 1, and a support component 3 disposed at the bottom of the pull-out component 2.

[0023] Among them, the pull-out component 2 includes a movable frame 201, the outer surface of the movable frame 201 is movably connected to the inner wall of the protective shell 1, and a lithium battery energy storage mechanism 202 is provided inside the movable frame 201.

[0024] The support assembly 3 includes a movable plate 301, the outer surface of which is movably connected to the inner cavity of the movable frame 201. Both sides of the movable plate 301 are hinged to a connecting plate 302 located on the outer side of the movable frame 201. The other end of the connecting plate 302 is hinged to a support frame 303, and the other end of the support frame 303 is hinged to the inner wall of the movable frame 201. The inner cavity of the movable frame 201 is provided with a threaded rod 306, the outer side of which extends to the outside of the movable frame 201, and the outer surface of the threaded rod 306 is threadedly sleeved with the inner wall of the movable plate 301.

[0025] When the operator pulls the movable frame 201 out of the protective shell 1, and a portion of the movable frame 201 is pulled out, the threaded rod 306 is rotated. The threaded rod 306 drives the movable plate 301 to move within the cavity of the movable frame 201. At the same time, the movable plate 301 drives the connecting plate 302 to move. Due to the hinge between the connecting plate 302 and the support frame 303, the connecting plate 302 drives the support frame 303 to push out from the inside of the movable frame 201, so that the end of the support frame 303 contacts the ground. Then, the entire movable frame 201 is pulled out from the protective shell 1. Thus, the support frame 303 supports the movable frame 201 and the lithium battery energy storage mechanism 202, preventing damage caused by the heavy weight when the movable frame 201 is pulled out, thus bringing convenience to the operator.

[0026] Example 2

[0027] like Figure 2 and Figure 4 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the inner cavities on both sides of the movable frame 201 are provided with limit blocks 203, and the outer side of the limit blocks 203 is connected to the inner wall of the protective shell 1.

[0028] When the operator pulls out the movable frame 201, the limit block 203 limits the entire movable frame 201 to prevent it from shifting during the pull.

[0029] Among them, the bottom of the movable frame 201 is provided with a pulley 204, and the bottom of the pulley 204 is movably connected to the inside of the protective shell 1;

[0030] When the operator pulls out the movable frame 201, the pulley 204 at the bottom of the movable frame 201 reduces the friction between the movable frame 201 and the protective shell 1, making it easier for the operator to pull the movable frame 201 out of the protective shell 1 as a whole, thus reducing the pulling force required by the operator.

[0031] Among them, the inner wall of the movable frame 201 is provided with a connecting rod 305, and the outer surface of the connecting rod 305 is movably connected to the inner wall of the movable plate 301;

[0032] When the threaded rod 306 is rotated, the movable plate 301 moves on the outer surface of the connecting rod 305 through the threaded rod 306. In turn, the connecting rod 305 enables the movable plate 301 to have a good limiting effect during the movement, so as to prevent the position from being deviated.

[0033] Among them, the other end of the support frame 303 is provided with a roller 304, and the outer surface of the roller 304 is movably connected to the inner wall of the protective shell 1;

[0034] Rotating the threaded rod 306 causes the movable plate 301 to drive the connecting plate 302 to support the support frame 303, allowing it to unfold from the bottom of the movable frame 201. This brings the roller 304 at the end of the support frame 303 into contact with the ground, making it easier for the operator to pull out the remaining part of the movable frame 201.

[0035] The protective shell 1 has heat dissipation holes on its outer side and mounting grooves on both the top and bottom of the protective shell 1.

[0036] By providing heat dissipation holes on the outside of the protective shell 1, heat dissipation is provided during the operation of the lithium battery energy storage mechanism 202, so as to prevent the temperature generated by the lithium battery energy storage mechanism 202 from not being able to dissipate and thus prevent damage to the lithium battery energy storage mechanism 202. At the same time, the mounting slots fix the protective shell 1 in a suitable position, making it convenient for operators to install and use.

[0037] Working principle and usage process of this utility model:

[0038] First, when the operator is inspecting the lithium battery energy storage mechanism 202, the movable frame 201 is pulled outward. The movable frame 201 and the lithium battery energy storage mechanism 202 are pulled out from inside the protective shell 1 via the pulley 204. After being pulled out a certain distance, the threaded rod 306 is rotated, which causes the movable plate 301 to move on the outer surface of the connecting rod 305. The movable plate 301 drives the connecting plate 302 to unfold the support frame 303, so that the outer surface of its roller 304 contacts the ground. Then, the movable frame 201 is pulled out from inside the protective shell 1 as a whole via the roller 304 and the pulley 204. The support frame 303 supports the front end of the movable frame 201 to prevent damage, which brings convenience to the operator.
