[0037] like Figure 1 As shown, the embodiment of the present application provides a battery storage box 100, which is mainly used to store lithium batteries. The battery storage box 100 includes a box cover 110, a storage box 120 and a storage member 130.

[0038] The storage box 120 includes a base 121 and a box body 122 that are fixedly connected, and a box cover 110 is removably disposed on the storage box 120 to take out or put in the batteries.

[0039] The storage member 130 is stored in the storage box 120. The storage member 130 has a plurality of independent storage spaces 132. The storage spaces 132 have openings 1313, so that the plurality of batteries can be stored separately, making each battery more stable and not easy to fall over. When the storage box 120 is deformed by collision, only the batteries in the collision area are affected, and the batteries in other areas are not affected, thereby improving the safety of battery storage.

[0040] The storage member 130 and the storage box 120 are both made of metal, which improves the structural strength and deformation resistance of the storage member 130 and the storage box 120. The storage member 130 is welded to the base 121 and / or the box body 122, so that the connection structure between the storage member 130 and the storage box 120 is stable, which can effectively protect the battery in the event of an impact and improve the safety of battery storage.

[0041] The base 121 is provided with a plurality of oblong holes arranged at intervals, so as to facilitate fixing the storage box 120 and the transportation vehicle, reduce the movement of the storage box 120, and improve the safety of battery storage.

[0042] In some embodiments, Figure 2 As shown, the storage member 130 includes a plurality of storage boxes 131 .

[0043] In the related art, a plurality of horizontal plates and vertical plates are usually cross-arranged to form a grid for placing batteries. Although such a structure reduces the cost, the cross structure composed of the horizontal plates and vertical plates is prone to deformation, resulting in the need to replace the entire cross structure. The present application provides multiple storage boxes 131, and only the deformed storage boxes 131 need to be replaced, while the remaining storage boxes 131 can continue to be used, thereby reducing maintenance costs.

[0044] In this embodiment, a plurality of storage boxes 131 are distributed in an array to completely fill the box body 122, thereby improving the space utilization of the box body 122 and improving the strength of the combined structure of the box body 122 and the storage member 130, making the combined structure less likely to deform and improving the safety of battery storage.

[0045] In some embodiments, the storage box 131 includes a side panel 1311 and a bottom panel.

[0046] The side plates 1311 between two adjacent storage boxes 131 are connected so that all the storage boxes 131 are connected to form a stable whole, and the batteries stored in the storage boxes 131 are prevented from falling off.

[0047] The side plate 1311 and the bottom plate are connected to define a receiving space 132 . The bottom plate faces away from the opening 1313 and is fixedly connected to the base 121 . The battery can be inserted into or removed from the receiving space 132 through the opening 1313 , which is convenient for operation.

[0048] In this embodiment, the cross section of the side plate 1311 is circular or rectangular. It can be understood that the shape of a conventional lithium battery is a hexahedron or a cylinder, and the shape of the side plate 1311 is correspondingly set to a hexahedron or a cylinder, which matches the conventional shape of the lithium battery and improves the practicality of the storage member 130. Of course, in other embodiments, the shape of the cross section of the side plate 1311 can also be adaptively adjusted according to the specific shape of the lithium battery.

[0049] The battery storage box in the related art has poor stability in fixing the box body and the box cover, which easily causes the battery storage box to be opened by mistake during transportation.

[0050] In view of the above problems, in some embodiments, Figure 2 and Figure 3 As shown, the box cover 110 includes a cover plate 111 , two sliding connection plates 112 and a plurality of fixing members 113 .

[0051] The cover plate 111 and the base 121 are disposed opposite to each other and spaced apart from each other.

[0052] Two sliding connection plates 112 are respectively arranged at opposite ends of the cover plate 111, and a protrusion 1121 is arranged on one side of the sliding connection plate 112 close to the box body 122, and a slide groove 1221 is arranged at a position of the box body 122 corresponding to the protrusion 1121, and the protrusion 1121 and the slide groove 1221 are slidably matched to make the box cover 110 and the storage box 120 detachably connected. Exemplarily, the protrusion 1121 is a convex strip or a convex block. By providing the protrusion 1121 and the slide groove 1221, the box cover 110 is covered on the box body 122, so that the box cover 110 and the box body 122 are quickly aligned and connected.

[0053] The sliding connection plate 112 is also provided with a plurality of through holes 1122, which are located on the side of the protrusion 1121 structure close to the cover plate 111 and are spaced apart along the extension direction of the slide groove 1221. A fixing member 113 is correspondingly inserted into a through hole 1122, and the fixing member 113 is movably connected to the hole wall of the through hole 1122. By providing a plurality of fixing members 113, the stability of the box cover 110 installed on the upper end of the storage box 120 body is increased, so that the box cover 110 is convenient for protecting the batteries stored in the storage member 130.

[0054] In this embodiment, if Figure 4 As shown, the through hole 1122 is a threaded hole, and the fixing member 113 is a screw, which is convenient for processing and reduces material cost. The screw is screwed forward or reversely to move the end of the screw toward or away from the box body 122, so that the box cover 110 and the storage box 120 are in a fixed state and a movable state. Of course, in other embodiments, the box cover 110 and the storage box 120 can also be fixed and movable by clamping.

[0055] In the related art, the buffering performance of the battery is insufficient when it is stored in the storage box, so that the battery is easily damaged by the vibration of the box.

[0056] In view of the above problems, in some embodiments, Figure 4 and Figure 5 As shown, the battery storage box 100 further includes a plurality of limiting members 140 .

[0057] A stopper 140 is correspondingly received in a storage box 131 to fix the battery in the storage box 131 and also to buffer the battery when the box body 122 vibrates.

[0058] The limiting member 140 includes a sleeve 141 , a plurality of elastic clips 142 and an elastic stopper 143 .

[0059] The sleeve 141 is disposed on the inner side of the storage box 131. Exemplarily, the shape of the sleeve 141 matches the shape of the interior of the storage box 131. The sleeve 141 is fitted and fixed to the surfaces of the side panel 1311 and the bottom panel, thereby increasing the space for storing batteries.

[0060] A plurality of elastic clips 142 are disposed in the sleeve 141 and are spaced apart along the circumference of the sleeve 141. The elastic clips 142 are in the form of thin sheets, and their length is the same as the depth of the sleeve 141. One long side of the clip is fixedly connected to the inner wall of the sleeve 141, and the other long side faces the center of the sleeve 141, so that the battery is surrounded by the plurality of elastic clips 142. In this way, when the storage box 120 vibrates, the battery squeezes the elastic clips 142, so that the battery is stably stored inside the storage box 131.

[0061] In some embodiments, the sleeve 141 may be made of an elastic material to prevent the battery from directly colliding with the side plate 1311 or the bottom plate and causing damage.

[0062] The elastic stopper 143 is connected to the cover plate 111. When the box cover 110 is connected to the storage box 120, the elastic stopper 143 is arranged at the opening 1313 of the accommodating space. Figure 4 As shown, the elastic stopper 143 is a small protrusion, and the number of the elastic stopper 143 corresponds to the number of the storage boxes 131, and the elastic stopper 143 corresponds to the opening 1313 of the storage box 131. In this way, the battery can be prevented from directly colliding with the cover plate 111 and causing damage, and the thickness of the cover plate 111 can also be reduced. Of course, a large elastic pad can also be provided on the cover plate 111, which can also prevent the battery from directly colliding with the cover plate 111 and causing damage.

[0063] The elastic stopper 143 is bonded and fixed to the cover plate 111 by glue.

[0064] The embodiment of the present application further provides an energy storage device, comprising at least one battery storage box 100 in any of the above embodiments. Therefore, the device has all the beneficial effects of the battery storage box 100 in any of the above embodiments, which will not be described in detail here.
