[0032] See also Figures 1 to 3The energy storage box 100 of the present application includes a housing 10, a handle assembly 20 and a connection assembly 40, wherein the handle assembly 20 is disposed on the housing 10. The connection assembly 40 is disposed on the housing 10, and the connection assembly 40 is used to connect with the handle assembly 20 of another energy storage box 100, so that the two energy storage boxes 100 are connected.

[0033] In the energy storage box 100 of the present application, when multiple energy storage boxes 100 need to be stacked on each other, the handle assembly 20 can form a fixed structure with the connection assembly 40 to connect and limit the positions between the multiple energy storage boxes 100 and lock the multiple energy storage boxes 100, so as to make the connection between the energy storage boxes 100 more stable. When the energy storage boxes 100 are stacked on each other, the connection assembly 40 can not occupy the external space of the energy storage box 100, and the stacked multiple energy storage boxes 100 are more stable and not easy to tip over or tilt.

[0034] The energy storage box 100 is further described below with reference to the accompanying drawings.

[0035] See also Figure 2 and Figure 3 In some embodiments, the housing 10 is roughly a box structure with an accommodating cavity inside. The accommodating cavity can be used to accommodate the internal components of the energy storage box 100, and the housing 10 can be installed with other structures of the energy storage box 100, such as the handle assembly 20, the energy storage assembly and / or the connecting assembly 40. The shape of the cross section of the housing 10 includes but is not limited to a circle, a quadrilateral, a pentagon or a hexagon. The material of the housing 10 includes but is not limited to metal, plastic, resin or rubber. When multiple energy storage boxes 100 are stacked on each other, the housings 10 of the multiple energy storage boxes 100 can contact each other and be fixed to each other through partial structures.

[0036] Specifically, in some embodiments, the housing 10 includes a first surface 101 and a third surface 103 facing each other. A plurality of energy storage boxes 100 can be stacked on each other along the height direction of the housing 10. The height direction of the housing 10 can be either the direction in which the first surface 101 of the housing 10 points to the third surface 103 of the housing 10, or the direction in which the third surface 103 of the housing 10 points to the first surface 101 of the housing 10, which is not limited here. For example, when two energy storage boxes 100 are stacked on each other, the third surface 103 of the housing 10 of one energy storage box 100 can be opposite to and in contact with the first surface 101 of the housing 10 of the other energy storage box 100, so that the two energy storage boxes 100 can be stacked on each other.

[0037] More specifically, in some embodiments, the housing 10 further includes a second surface 102 and a fourth surface 104 connected to the first surface 101 of the housing 10 and the third surface 103 of the housing 10, respectively, and the second surface 102 of the housing 10 is opposite to the fourth surface 104 of the housing 10. That is, the second surface 102 of the housing 10 and the fourth surface 104 of the housing 10 are both two side surfaces of the housing 10 that are not in contact. In some embodiments, the second surface 102 of the housing 10 and the fourth surface 104 of the housing 10 are the front side and the rear side of the housing 10, respectively. In other embodiments, the second surface 102 of the housing 10 and the fourth surface 104 of the housing 10 are the left side and the right side of the housing 10, respectively.

[0038] Further, in some embodiments, at least one of the first surface 101 of the housing 10 and the second surface 102 of the housing 10 is provided with a groove 11. The groove 11 is a structure provided on the surface of the housing 10 and used to accommodate the handle assembly 20. In some embodiments, the groove 11 is a sunken groove provided on the surface of the housing 10, and the handle assembly 20 can be installed on the side wall of the groove 11 or on the bottom wall of the groove 11. In other embodiments, the groove 11 is a through groove communicating with the interior of the housing 10, and the handle assembly 20 can only be installed on the side wall of the groove 11.

[0039] Furthermore, in some embodiments, the groove 11 is provided on the first surface 101 of the housing 10, and the handle assembly 20 is also provided on the first surface 101 of the housing 10, wherein the handle assembly 20 includes a handle 21 and a connecting shaft 23, and the handle 21 is rotatably and / or movably mounted on the groove 11 via the connecting shaft 23. The handle 21 also includes a second side 203 opposite to the first side 201 of the handle 21, the first side 201 of the handle 21 faces outside the groove 11, the second side 203 of the handle 21 faces inside the groove 11, and the first side 201 of the handle 21 and the second side 203 of the handle 21 are arranged opposite to each other.

[0040] When the handle 21 is in an open state relative to the first surface 101 of the housing 10, in one example, the first side 201 of the handle 21 can be tilted relative to the first surface 101 of the housing 10, so that the handle 21 as a whole can be flipped relative to the housing 10, and at this time, a lifting space for the user to reach in and lift the energy storage box 100 is formed between the second side 203 of the handle 21 and the groove 11, so that the user can lift the energy storage box 100 through the handle 21. In another example, the first side 201 of the handle 21 is still parallel to the first surface 101 of the housing 10, but along the height direction of the housing 10, the first side 201 of the handle 21 is higher than the first surface 101 of the housing 10. At this time, the handle 21 is separated from the housing 10, and a lifting space for the user to reach in and lift the energy storage box 100 can still be formed between the second side 203 of the handle 21 and the groove 11, and the user can reach his hand into the lifting space and lift the energy storage box 100.

[0041] When the handle 21 is in a closed state relative to the first surface 101 of the housing 10, in one example, the first side 201 of the handle 21 can be tilted relative to the first surface 101 of the housing 10, and at this time, along the height direction of the housing 10, the tilted handle 21 has a highest point, and the highest point of the tilted handle 21 is still lower than the first surface 101 of the housing 10, that is, the entire structure of the handle assembly 20 is disposed in the groove 11. At this time, the entire structure of the handle assembly 20 does not protrude from the housing 10, so when the housing 10 is stacked along the height direction of the housing 10, the handle assembly 20 will not conflict with the second surface 102 of the housing 10, so that there is a larger gap between two adjacent energy storage boxes 100, so that the stacking of multiple energy storage boxes 100 can be more stable. In another example, the first side 201 of the handle 21 can be parallel to the first surface 101 of the housing 10. In this case, the first side 201 of the handle 21 and the first surface 101 of the housing 10 can be located in the same plane, and the plane where the first side 201 of the handle 21 is located can also be lower than the first surface 101 of the housing 10, that is, along the height direction of the housing 10, the first side 201 of the handle 21 is not higher than the first surface 101 of the housing 10. In this case, all structures of the handle assembly 20 do not protrude from the housing 10, so when multiple energy storage boxes 100 are stacked along the height direction of the housing 10, the first side 201 of the handle 21 of the energy storage box 100 located at the bottom will not first conflict with the second surface 102 of the housing 10 of the energy storage box 100 located above the energy storage box 100, and the second surface 102 of the housing 10 of the energy storage box 100 located at the top can conflict with the first surface 101 of the housing 10 of the energy storage box 100 located at the bottom, so that there will be no large gap between the two adjacent energy storage boxes 100.

[0042] In other embodiments, the groove 11 is provided on the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10. In this case, the handle assembly 20 can be provided on the third surface 103 of the housing 10 or on the fourth surface 104 of the housing 10. In the case where the handle assembly 20 includes multiple handle assemblies 20, the multiple handle assemblies 20 can also be provided on the third surface 103 of the housing 10 and the fourth surface 104 of the housing 10 at the same time, and each handle assembly 20 corresponds to the groove 11 and is provided in the groove 11. In some examples, only one handle assembly 20 is provided in each groove 11. In other examples, multiple handle assemblies 20 can be provided in each groove 11. And the multiple handle assemblies 20 do not interfere with each other, and the user can lift the energy storage box 100 through any handle assembly 20.

[0043] Specifically, in the case where the handle assembly 20 is disposed on the third surface 103 of the shell 10 and / or the fourth surface 104 of the shell 10, if the multiple energy storage boxes 100 are still stacked along the height direction of the shell 10, at this time, only the first surface 101 of the shell 10 of one of the energy storage boxes 100 is opposite to and in contact with the second surface 102 of the shell 10 of the adjacent energy storage box 100. Therefore, when the handle assembly 20 is in the closed state, it may not protrude from the third surface 103 of the shell 10 and / or the fourth surface 104 of the shell 10, and may also protrude from the third surface 103 of the shell 10 and / or the fourth surface 104 of the shell 10. If the multiple energy storage boxes 100 are still stacked in the direction from the third surface 103 of the shell 10 to the fourth surface 104 of the shell 10, at this time, the third surface 103 of the shell 10 of one of the energy storage boxes 100 is opposite to and in contact with the fourth surface 104 of the shell 10 of the adjacent energy storage box 100, therefore, when the handle assembly 20 is in the closed state, the handle 21 must not protrude from the third surface 103 of the shell 10 and / or the fourth surface 104 of the shell 10.

[0044] More specifically, when the handle 21 is in an open state relative to the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10, in one example, the first side 201 of the handle 21 can be tilted relative to the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10, so that the handle 21 as a whole is flipped relative to the housing 10, and at this time, a lifting space for the user to reach in and lift the energy storage box 100 is formed between the second side 203 of the handle 21 and the groove 11, so that the user can lift the energy storage box 100 through the handle 21. In another example, the first side 201 of the handle 21 is still parallel to the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10, but along the height direction of the housing 10, the first side 201 of the handle 21 is higher than the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10. At this time, the handle 21 is separated from the shell 10 , and a space for the user to reach in and lift can still be formed between the second side 203 of the handle 21 and the groove 11 , so that the user can reach into the lifting space and lift the energy storage box 100 .

[0045] When the handle 21 is in a closed state relative to the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10, in one example, the first side 201 of the handle 21 can be tilted relative to the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10, and at this time, along the height direction of the housing 10, the tilted handle 21 has a highest point, and the highest point of the tilted handle 21 is still lower than the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10, that is, the entire structure of the handle assembly 20 is disposed in the groove 11. At this time, the entire structure of the handle assembly 20 does not protrude from the housing 10, so when the housing 10 is stacked along the third surface 103 of the housing 10 pointing to the fourth surface 104 of the housing 10, the handle assembly 20 will not conflict with the second surface 102 of the housing 10, so that there is a larger gap between two adjacent energy storage boxes 100, so that the stacking of multiple energy storage boxes 100 can be more stable. In another example, the first side 201 of the handle 21 can be parallel to the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10. In this case, the first side 201 of the handle 21 and the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10 can be located in the same plane, and the plane where the first side 201 of the handle 21 is located can also be lower than the third surface 103 of the housing 10 and / or the fourth surface 104 of the housing 10. In this case, all structures of the handle assembly 20 do not protrude from the housing 10.

[0046] See also Figure 2 and Figure 3In some embodiments, the handle assembly 20 is a structure disposed on the surface of the housing 10 and capable of moving relative to the housing 10. The handle assembly 20 can be used not only to extract the energy storage box 100, but also to connect multiple energy storage boxes 100 or disconnect multiple energy storage boxes 100 from each other. The handle 21 of the handle assembly 20 can move relative to the housing 10 so that the first side 201 of the handle 21 is inclined and protrudes relative to the housing 10 or the first side 201 of the handle 21 is parallel and protrudes relative to the housing 10. In some embodiments, the handle 21 can move relative to the housing 10 (for example, the handle 21 slides relative to the housing 10). When the handle 21 slides relative to the housing 10 to a first position, the handle 21 opens the groove 11 so that a structure capable of extracting the energy storage box 100 (for example, a human hand, a manipulator, or other structure capable of applying force to the handle 21 to lift the energy storage box 100) can extend into the groove and lift the energy storage box 100 through the handle 21. When the handle 21 slides relative to the housing 10 to a second position, the handle 21 blocks the groove 11. In other embodiments, the handle assembly 20 further includes a connecting shaft 23. The connecting shaft 23 is connected to the handle 21 and disposed in the groove 11, and the opposite ends of the connecting shaft 23 are respectively connected to the two opposite inner walls of the groove 11. The connection method between the connecting shaft 23 and the handle 21 includes but is not limited to: the connecting shaft 23 is passed through the handle 21, the connecting shaft 23 is a convex point disposed between the handle 21 and the inner wall of the groove 11, or the connecting shaft 23 is two short shafts symmetrically disposed between the handle 21 and the inner wall of the groove 11. The handle 21 can rotate relative to the housing 10 around the connecting shaft 23, and the connecting shaft 23 is fixed relative to the inner wall of the groove 11.

[0047] Specifically, in some embodiments, one side of the handle 21 has a raised plate-like structure, and the material of the handle 21 includes, but is not limited to, hard materials such as metal, plastic, or rubber. The handle 21 includes a plate-like end face portion 211 and a connecting portion 213 protruding from the sub-end face portion 211. In some embodiments, the end face portion 211 and the connecting portion 213 are integrally formed, and the materials of the end face portion 211 and the connecting portion 213 can be the same or different. In other embodiments, the end face portion 211 and the connecting portion 213 are separately formed, and the end face portion 211 and the connecting portion 213 can be installed to each other in a detachable manner such as a snap connection, a threaded connection, or a bolt connection, or can be installed to each other in an irremovable direction by means of gluing, hot-melt connection, or welding, etc., and there is no limitation here.

[0048] More specifically, in some embodiments, the end face portion 211 includes a first side 2111 and a second side 2113 opposite to each other, the first side 2111 of the end face portion 211 is away from the groove 11, and the second side 2113 of the end face portion 211 faces the inside of the groove 11. That is, the first side 2111 of the end face portion 211 is the first side 201 of the handle 21, and the second side 2113 of the end face portion 211 is the second side 203 of the handle 21. When the handle 21 is in a closed state, the first side 2111 of the end face portion 211 is not higher than the surface of the housing 10. The connecting portion 213 is provided on the second side 2113 of the end face portion 211 and extends into the groove 11 to connect with the connecting shaft 23. In some embodiments, the connecting portion 213 includes two separate sub-portions, the two sub-portions are respectively arranged on the second side 2113 of the end face portion 211 along the extending direction of the connecting shaft 23, and the two ends of the connecting shaft 23 respectively pass through the two sub-portions of the connecting portion 213 and are installed in the groove 11.

[0049] See also Figure 2 and Figure 3 In some embodiments, the handle assembly 20 may further include a reset member 30, which is generally a structure capable of applying force to the handle 21 and restoring the handle 21 from the open state to the closed state. Specifically, the reset member 30 may be a torsion spring sleeved on the connecting shaft 23, one end of the reset member 30 is at least connected to the handle 21, and the other end of the reset member 30 may be a free end or may be fixedly connected to the connecting shaft 23. When the handle 21 is in the open state, the handle 21 is subjected to force and rotates around the connecting shaft 23 under the action of external force, and the reset member 30 is stretched at this time. Since the reset member 30 is elastic, the reset member 30 can apply force to the handle 21 so that the handle 21 has a tendency to restore to the closed state. When the external force pulling the handle 21 is removed, the reset member 30 can apply force to the handle 21 to restore the reset member 30 to its original state, and the handle 21 is subjected to force and switches from the open state to the closed state.

[0050] See also Figures 2 to 4 In some embodiments, the energy storage box 100 may further include a connecting assembly 40, which is a structure for connecting two adjacent and stacked energy storage boxes 100. In some embodiments, the connecting assembly 40 is detachably provided on the housing 10 and the handle 21. In other embodiments, the connecting assembly 40 is non-detachably provided on the housing 10 and the handle 21. When a plurality of energy storage boxes 100 are stacked on each other, the connecting assembly 40 can fix two adjacent energy storage boxes 100, so as to prevent the stacked energy storage boxes 100 from being unstable, tilting or even tipping over to damage the stacked energy storage boxes 100.

[0051] Specifically, please combine Figure 2In some embodiments, the positioning member 25 is a structure that is detachably disposed on the handle 21 and can extend from the handle 21 through the groove 11 into the housing 10 to connect with the connecting assembly 40 of another energy storage box 100, and the connecting assembly 40 includes a handle 41. The handle 41 is a structure that is disposed on the first surface 101 of the housing 10 and can be connected to the positioning member 25. When multiple energy storage boxes 100 are stacked on each other, the positioning member 25 can be installed on the second side 203 of the handle 21 and extend into the housing 10.

[0052] The case where the handle 21 can slide relative to the housing 10 is used for explanation: when the handle 21 slides to the first position relative to the housing 10, in one example, the handle 21 can drive the positioning member 25 to move (move and / or rotate) so that the positioning member 25 is disengaged from the handle 41 of another energy storage box 100, and the two adjacent energy storage boxes 100 are unlocked from each other. In another example, the handle can drive the positioning member 25 to move (move and / or rotate) so that the positioning member 25 applies force to the handle 41 of another energy storage box 100, and the two adjacent energy storage boxes 100 are locked to each other. When the handle 21 slides to the second position relative to the housing 10, in one example, the handle 21 can drive the positioning member 25 to move (move and / or rotate) so that the positioning member 25 is disengaged from the handle 41 of another energy storage box 100, and the two adjacent energy storage boxes 100 are unlocked from each other. In another example, the handle can drive the positioning member 25 to move (move and / or rotate) so that the positioning member 25 applies force to the handle 41 of another energy storage box 100, and the two adjacent energy storage boxes 100 are locked with each other.

[0053] The case where the handle 21 can rotate relative to the housing 10 is used for explanation: when the handle 21 rotates relative to the housing 10 to be in a closed state, in one example, the handle 21 can drive the positioning member 25 to move (move and / or rotate) so that the positioning member 25 is disengaged from the handle 41 of another energy storage box 100, and the two adjacent energy storage boxes 100 are unlocked from each other. In another example, the handle can drive the positioning member 25 to move (move and / or rotate) so that the positioning member 25 applies force to the handle 41 of another energy storage box 100, and the two adjacent energy storage boxes 100 are locked to each other. When the handle 21 rotates relative to the housing 10 to be in an open state, in one example, the handle 21 can drive the positioning member 25 to move (move and / or rotate) so that the positioning member 25 is disengaged from the handle 41 of another energy storage box 100, and the two adjacent energy storage boxes 100 are unlocked from each other. In another example, the handle can drive the positioning member 25 to move (move and / or rotate) so that the positioning member 25 applies force to the handle 41 of another energy storage box 100, and the two adjacent energy storage boxes 100 are locked with each other.

[0054] More specifically, in some embodiments, the second surface 102 of the housing 10 may also be provided with a clearance groove 13 communicating with the interior of the housing 10, and the clearance groove 13 can be used to accommodate the handle 41. When multiple energy storage boxes 100 are stacked on each other, the handle 41 of the lower energy storage box 100 can extend into the upper energy storage box 100 through the clearance groove 13 of the upper energy storage box 100 to connect with the positioning member 25 of the upper energy storage box 100, so that two adjacent energy storage boxes 100 are fixed to each other. In some embodiments, please combine Figure 4 and Figure 5 The handle 41 and the handle assembly 20 are both disposed on the first surface 101 of the housing 10. The handle 41 is disposed outside the groove 11 and corresponds to the position where the positioning member 25 is disposed on the handle assembly 20. Figure 6 and Figure 7 The handle 41 is disposed on the first surface 101 of the shell 10, and the handle assembly 20 is disposed on the third surface 103 of the shell 10 and / or the fourth surface 104 of the shell 10. Along the height direction of the shell 10, the position of the handle 41 corresponds to the position of the positioning member 25 away from the handle assembly 20, so that the positioning member 25 can be combined with the handle 41.

[0055] More specifically, please combine Figure 3 In some embodiments, the positioning member 25 includes a first end 251 and a second end 253 opposite to each other. The first end 251 of the positioning member 25 is detachably disposed on the handle 21, and the second end 253 of the positioning member 25 extends into the housing 10. In the case where the handle 41 and the handle assembly 20 are both disposed on the first surface 101 of the housing 10, please combine Figure 4 and Figure 5 , the direction from the first end 251 of the positioning member 25 to the second end 253 of the positioning member 25 is roughly the height direction of the housing 10.

In the case where the handle 41 is disposed on the first surface 101 of the housing 10 and the handle assembly 20 is disposed on the fourth surface 104 of the housing 10, please combine Figure 6 and Figure 7, the direction from the first end 251 of the positioning member 25 to the second end 253 of the positioning member 25 is roughly the direction from the fourth surface 104 of the housing 10 to the third surface 103 of the housing 10. The second end 253 of the positioning member 25 may be provided with a hook 255. When multiple energy storage boxes 100 are stacked on each other, the hook 255 of the positioning member 25 of the upper energy storage box 100 is connected to the handle 41 of the lower energy storage box 100 to fix the two adjacent energy storage boxes 100. The hook 255 and the handle 41 are detachably connected, and the connection methods include but are not limited to snap connection, threaded connection or bolt connection.

[0056] Also specifically, in some embodiments, the handle 41 includes a first sub-portion 411, a second sub-portion 413 and a third sub-portion 415. The first sub-portion 411 and the second sub-portion 413 are separated from each other, and the first sub-portion 411 and the second sub-portion 413 are both arranged on the first surface 101 of the housing 10. The two ends of the third sub-portion 415 are respectively connected to the first sub-portion 411 and the second sub-portion 413 and separated from the housing 10, so that there is a gap between the third sub-portion 415 and the first surface 101 of the housing 10 for the hook 255 to pass through. When a plurality of energy storage boxes 100 are stacked on each other, the third sub-portion 415 of the lower energy storage box 100 is opposite to the positioning member 25 of the upper energy storage box 100 and connected to each other. When the groove 11 is arranged on the first surface 101 of the housing 10, the first sub-portion 411 and the second sub-portion 413 are respectively located on opposite sides of the groove 11, and the third sub-portion 415 spans the groove 11 and corresponds to the second end 253 of the positioning member 25. In the case where the groove 11 is provided on the third surface 103 of the housing 10, along the direction from the third surface 103 of the housing 10 to the fourth surface 104 of the housing 10, the projections of the first sub-portion 411 and the second sub-portion 413 onto the fourth surface 104 of the housing 10 are located on opposite sides of the projection of the groove 11 onto the fourth surface 104 of the housing 10, and the projection of the third sub-portion 415 onto the fourth surface 104 of the housing 10 intersects with the projection of the groove 11 onto the fourth surface 104 of the housing 10.
