However, this method has some problems that when the battery pack 2 is pushed horizontally between the two L-shaped brackets, because the vertical plates on the two L-shaped brackets are in clearance fit with the battery pack 2, the side wall of the battery pack 2 is easy to be blocked with the side wall of the L-shaped bracket during the process of pushing the battery pack 2 into the box 1, so that the assembly is difficult.
Therefore, the embodiment further improves the structure of the energy storage battery box on the basis of the technical scheme. Specifically, in this embodiment, a guide assembly 4 is further disposed in the installation space S, and referring to fig. 2 to 5, the guide assembly 4 includes a guide rod 41 and a docking device 42; the two guide rods 41 are arranged in parallel, and the two guide rods 41 are horizontally positioned on the same horizontal plane above the bearing assembly 3 and are fixedly connected with the inner wall of the box body 1 respectively; the docking device 42 is symmetrically provided with two groups, which are respectively positioned at two sides of the battery pack 2 and are used for sliding connection with the guide rod 41. Therefore, in the process of inserting the battery pack 2 into the installation space S, the battery pack 2 can be guided and positioned in the horizontal direction and the vertical direction in the installation space S under the rolling transmission action of the matched bearing assembly through the butt joint device 42 and the guide rod 41.
In order to realize sliding connection between the docking device 42 and the guide rod 41, so as to play a role in horizontally positioning the battery pack 2 in the process of being inserted into the installation space S, the embodiment shows some preferred embodiments of the docking device 42, specifically, the docking device 42 includes a guide sleeve 421 fixedly disposed at the bottom end of the side wall of the battery pack 2, the guide sleeve 421 is flush with the direction of inserting the battery pack 2 into the installation space S, and the guide sleeve 421 is used for being sleeved on the guide rod 41 and in sliding connection with the guide rod 41.
By adopting the above technical scheme, when the battery pack 2 is inserted into the installation space S, the battery pack 2 is placed on the bearing plate, the guide sleeves 421 on two sides of the battery pack 2 are aligned with the guide rods 41, the battery pack 2 is pushed, the guide sleeves 421 are sleeved on the guide rods 41, the battery pack 2 is horizontally conveyed on the roller 32 on one hand in the horizontal pushing process of the battery pack 2, and on the other hand, the smooth and steady in-out installation space S of the battery pack 2 is realized through the sliding fit of the guide sleeves 421 and the guide rods 41, and meanwhile, the battery pack 2 is horizontally and vertically positioned.
In the above embodiment, the length of the guide sleeve 421 is the same as the length of the battery pack 2, and in the sliding process of the guide sleeve 421 along the guide rod 41, the entire guide sleeve 421 always performs sliding friction with the guide rod 41, although the friction force of the sliding friction is small, the contact area between the guide sleeve 421 and the guide rod 41 is large, and a certain friction resistance still exists, so that the horizontal movement of the battery pack 2 is not smooth.
For this reason, in the present embodiment, the guide sleeve 421 is provided with a plurality of guide sleeves 421, and the plurality of guide sleeves 421 are provided at intervals. With this arrangement, the contact area between the guide sleeve 421 and the guide rod 41 can be reduced, so that the frictional force between the guide sleeve 421 and the guide rod 41, which is caused by sliding, can be reduced, and the battery pack 2 can be more labor-saving when entering and exiting the installation space S.

In this embodiment, a connecting plate 411 is also fixedly disposed between the guide rod 41 and the inner wall of the case 1, an arc-shaped groove 4211 is formed on one side of the guide sleeve 421 facing the guide rod 41 along the length direction thereof, and at least a portion of the guide rod 41 is connected to the arc-shaped groove 4211. Thus, when the battery pack 2 is inserted into the case 1, the guide bar 41 is aligned with the arc groove 4211, and then the battery pack 2 is pushed, so that a part of the guide bar 41 is inserted into the arc groove 4211, and at the same time, a part of the connection between the guide bar 41 and the connection plate 411 is positioned outside the guide sleeve 421.
As some alternative embodiments, the bottom of the arc-shaped groove 4211 has a drop-preventing portion 4212, and the drop-preventing portion 4212 is connected to a side of the guide bar 41 near the connection plate 411. Therefore, after the guide rod 41 is inserted into the arc-shaped groove 4211, the anti-falling part 4212 can limit one side, away from the guide sleeve 421, of the guide rod 41, so that the guide rod 41 is prevented from falling out of the sleeve during sliding, and the sliding connection stability of the guide sleeve 421 and the guide rod 41 is improved.
Because the guide sleeve 421 is sleeved on the guide rod 41, the gravity of the battery pack 2 is concentrated on the rollers 32 and the guide rod 41 at two sides, the gravity of the battery pack 2 can apply a downward load to the guide sleeve 421, so that the guide sleeve 421 is bent and deformed relative to the battery pack 2, and smooth sliding of the guide sleeve 421 and the guide rod 41 cannot be ensured. Therefore, the mounting groove 422 is fixed on the bottom surface of the side wall of the battery pack 2 and can be used as a part of the box body of the battery pack 2, so that the gravity of the battery pack 2 can be prevented from being completely loaded on the guide sleeve 421 through the protection of the mounting groove 422 to the guide sleeve 421, the guide sleeve 421 is prevented from bending and deforming, and the reliability of the mounting and dismounting of the battery pack 2 and the box body 1 is improved.
As some preferred embodiments, the guide sleeve 421 of this embodiment is a ball sleeve, and the ball sleeve is slidably matched with the guide rod 41, so that the friction force in the sliding process can be further reduced, and the battery pack 2 can more easily enter and exit the installation space S.
Preferably, a guide portion connected to the docking device 42 is provided on a side of the guide bar 41 facing the opening end of the installation space S in the length direction, and the guide portion in this embodiment is a rounded corner or a rounded corner, or is tapered, which is convenient for aligning the guide bar 41 with the guide sleeve 421, and when the battery pack 2 is pushed, the guide bar 41 can be automatically inserted into the guide sleeve 421, so that the alignment and installation are more flexible and quick.
