[0042] See also Figure 1-Figure 4 ,in Figure 1 A cross-sectional schematic diagram of a combined box 100 in a locked state provided in one embodiment of the present application is shown; Figure 2 A cross-sectional schematic diagram of a combined box 100 in an unlocked state provided in one embodiment of the present application is shown; Figure 3 A schematic structural diagram of a combined box 100 provided in one embodiment of the present application at a viewing angle is shown; Figure 4 A structural schematic diagram of a combined box 100 from another perspective provided in an embodiment of the present application is illustrated.

[0043] The box body 10 of the present application is provided with at least one latch 20 and / or at least one lock seat 30 , the lock seat 30 is located on the outside of the box body 10 , the first part 201 of the latch 20 is located in the inner cavity 12 of the box body 10 , and the second part 202 of the latch 20 is exposed outside the box body 10 .

[0044] Specifically, in one embodiment, Figure 1 and Figure 2 As shown, the combined box 100 includes three boxes 10, which are stacked in sequence. The lock seat 30 is arranged on the outside of one box 10 and extends toward another box 10 relatively above; the latch 20 extends along a direction perpendicular to the arrangement of the boxes 10, and includes a first part 201 and a second part 202, the first part 201 is located in the inner cavity 12 of the box 10 and is movably connected to the box 10, and the second part 202 extends into the through hole of the box 10 and is exposed to the box 10.

[0045] In the box 10 of the present application, at least one lock 20 of one box 10 is used to cooperate with at least one lock seat 30 of another box 10, and / or at least one lock seat 30 of one box 10 is used to cooperate with at least one lock of another box 10, so that the two boxes 10 are fixedly connected.

[0046] Specifically, in one embodiment, Figure 1 and Figure 2 As shown, three boxes 10 are stacked in sequence, and a lock seat 30 is fixed on one side of one box 10 facing the other box 10 relatively above. The lock seat 30 of one box 10 extends toward the other box 10 relatively above and extends into the inner cavity 12 of the other box 10. The latch 20 is located in the inner cavity 12 of one box 10, and an extension portion 11 is fixed on the inner surface of the inner cavity 12. The latch 20 is slidably connected with the extension portion 11, and the sliding direction of the latch 20 is perpendicular to the arrangement direction of the boxes 10. The first part 201 of the latch 20 is provided with a first bending portion 21, and the lock seat 30 is provided with a second bending portion 31. Both the first bending portion 21 and the second bending portion 31 extend along the arrangement direction of the boxes 10 and are bent at the ends. The bend at the end of the first bending portion 21 faces the lock seat 30, and the bend at the end of the second bending portion 31 faces the latch 20. Along the sliding direction of the latch 20 , the first bent portion 21 and the second bent portion 31 are engaged with each other so that the latch 20 and the lock seat 30 are locked with each other, thereby fixing the two adjacent boxes 10 .

[0047] In this embodiment, the lock seat 30 of the middle box body 10 extends into the inner cavity 12 of the upper box body 10 and is locked with the lock 20 of the upper box body 10, and the lock seat 30 of the lower box body 10 extends into the inner cavity 12 of the middle box body 10 and is locked with the lock 20 of the middle box body 10, thereby realizing the fixed connection of the three boxes 10.

[0048] The box 10 of the present application is provided with a lock 20 and / or a lock seat 30. The lock 20 of one of the two boxes 10 contacts and cooperates with the lock seat 30 of the other box 10 so that the lock 20 and the lock seat 30 are locked to each other. The mutually locked lock 20 and lock seat 30 can fix the two boxes 10 to prevent the stacked boxes 10 from tipping over or falling due to vibration or impact, thereby protecting the items in the boxes 10.

[0049] In existing boxes, the structure for realizing box interlocking is often arranged on the outside of the box, which requires a large space, so that the placement of the box also requires more space, which affects the placement and stacking of the box and is not conducive to improving space utilization.

[0050] In the box 10 of the present application, the latch 20 and the lock seat 30 that cooperate with each other contact and lock each other in the inner cavity 12 of one box 10 to achieve a fixed connection between the two boxes 10. The latch 20 and the lock seat 30 are at least partially arranged in the inner cavity 12 of one box 10. When the boxes 10 are placed, the latch 20 and the lock seat 30 do not need to occupy additional space, so that multiple boxes 10 can be stacked and placed more compactly, thereby improving space utilization.

[0051] In addition, placing both the lock 20 and the lock seat 30 in the inner cavity 12 can also protect the lock 20 and the lock seat 30, preventing the mutually locked parts of the lock 20 and the lock seat 30 from contacting or colliding with external components, causing the locking between the lock 20 and the lock seat 30 to fail.

[0052] At the same time, the locking and unlocking of the lock 20 and the lock seat 30 of the box 10 of the present application are simple. The second part 202 of the lock 20 is exposed on the box 10. The second part 202 is driven to move to drive the lock 20 to move relative to the lock seat 30, so that the lock 20 and the lock seat 30 can be in contact or not in contact, thereby realizing the locking and unlocking of the lock 20 and the lock seat 30. The operation of locking or unlocking the two boxes 10 is more convenient, and the time required for locking and unlocking operations is reduced.

[0053] The present application also provides a combined box 100, comprising at least two boxes 10, which are arranged in sequence, wherein a lock seat 30 of one box 10 extends into an inner cavity 12 of another adjacent box 10 and is locked with a latch 20, so that the two adjacent boxes 10 are fixedly connected.

[0054] The present application also provides an energy storage device, including at least one battery and two boxes 10, the box 10 is a battery box, the inner cavity 12 of the box 10 is used to accommodate batteries or the box 10 is a battery management system or at least one inverter; or includes at least one battery and a combined box 100, the combined box 100 is a battery box for accommodating batteries or the combined box 100 is at least one battery management system or inverter.

[0055] It is understandable that the vehicle vibrates during driving, which can easily cause relative displacement between the stacked boxes 10, causing the center of gravity of the boxes 10 to shift. When the vibration is too large, there is even a risk of the box 10 tipping over or falling, causing damage to the box 10 and the items inside the box 10. The box 10, combined box 100 and energy storage device of the present application can be applied to vehicles, and one of the box 10, combined box 100 and energy storage device is set in the vehicle compartment to reduce the displacement between the boxes 10 and prevent the box 10 from tipping over or falling.

[0056] It should be pointed out that the box 10, combined box 100 and energy storage device of the present application can not only be used on vehicles to prevent the box 10 from overturning or falling during transportation of the vehicle, but can also be used between other devices or components that need to be locked or unlocked, so that the locking and unlocking operations between devices or components are simple and convenient, and the space utilization rate is improved.

[0057] In one embodiment, the box body 10 includes an extension portion 11 , which is located on the inner wall of the inner cavity 12 and extends toward the geometric center of the box body 10 , and the first portion 201 of the latch 20 is movably connected to the box body 10 via the extension portion 11 .

[0058] In one embodiment, if Figure 1 and Figure 2 As shown, the extension portion 11 of one box body 10 is located on the inner surface of the inner cavity 12, and the end of the extension portion 11 extends toward the inside of the box body 10. The extension portion 11 is provided with a lock 20 and is movably connected to the extension portion 11. The lock seat 30 is fixed to the outside of the other box body 10. The lock seat 30 extends toward one box body 10 and extends into the inner cavity 12. The lock 20 and the lock seat 30 cooperate with each other to fix the two boxes 10.

[0059] It should be pointed out that the movable connection between the box body 10 and the latch 20 includes “a sliding connection between the box body 10 and the latch 20” and “a rotational connection between the box body 10 and the latch 20”.

[0060] In some embodiments, the movable connection between the box body 10 and the latch 20 includes “a sliding connection between the box body 10 and the latch 20 ” to achieve mutual locking between the latch 20 and the lock seat 30 .

[0061] In one embodiment, one end of the first part 201 of the latch 20 is slidably connected to the end of the extension portion 11 , and the other end is used to be locked with the lock seat 30 of another box 10 .

[0062] In one embodiment, if Figure 1 and Figure 2 As shown, one end of the first part 201 of the lock 20 is slidably connected to the extension part 11, and the sliding direction of the lock 20 is perpendicular to the arrangement direction of the two boxes 10. The other end is provided with a first bending portion 21, and the first bending portion 21 is used to engage with the second bending portion 31 of the lock seat 30 of the other box 10, so that the lock 20 and the lock seat 30 are locked with each other.

[0063] In one embodiment, one of the first part 201 of the latch 20 of one box 10 and the lock seat 30 of the other box 10 includes a protrusion, and the other includes a groove, and the protrusion is at least partially located in the groove, so that the latch 20 of one box 10 is engaged with the lock seat 30 of the other box 10.

[0064] In one embodiment, the latch 20 of one box 10 slides along a direction perpendicular to the arrangement direction of the boxes 10, the latch 20 is provided with a protrusion, and the protrusion extends along the sliding direction of the latch 20, the lock seat 30 of the other box 10 extends into the inner cavity 12 of one box 10, the lock seat 30 is provided with a groove, and the notch of the groove faces the latch 20. The latch 20 slides relative to the box 10 and drives the protrusion to move toward the groove of the lock seat 30, so that the protrusion extends into the groove, so as to realize the latch connection between the latch 20 and the lock seat 30.

[0065] In another embodiment, the lock seat 30 is provided with a protrusion, and the lock 20 is provided with a groove, the notch of the groove faces the lock seat 30, the lock 20 slides relative to the box body 10 and drives the groove to move toward the protrusion of the lock seat 30, so that the protrusion extends into the groove, and the lock 20 and the lock seat 30 can also be connected.

[0066] See also Figure 5-Figure 8 ,in Figure 5 A partial schematic diagram of a combined box 100 in a locked state at a viewing angle provided in an embodiment of the present application is shown; Figure 6 A partial schematic diagram of a combination box 100 in a locked state from another perspective provided in an embodiment of the present application is shown; Figure 7 A cross-sectional schematic diagram of a combination box 100 in a locked state from another perspective provided in an embodiment of the present application is shown; Figure 8 A cross-sectional schematic diagram of a combination box 100 in a locked state from another viewing angle provided in an embodiment of the present application is illustrated.

[0067] In one embodiment, the first part 201 of the lock 20 of one box body 10 includes a first bending portion 21, and the lock seat 30 of the other box body 10 includes a second bending portion 31. Along the sliding direction of the lock 20, the first bending portion 21 and the second bending portion 31 are bent in opposite directions, and the lock 20 slides relative to the box body 10 so that the first bending portion 21 and the second bending portion 31 are mutually engaged.

[0068] In one embodiment, if Figure 5-Figure 8 As shown, in a pair of mutually cooperating latches 20 and lock seats 30, the latch 20 is slidably connected to the extension portion 11, and the first part 201 of the latch 20 is provided with a first bending portion 21, which extends toward the lock seat 30 along a sliding direction perpendicular to the latch 20, and the end of the first bending portion 21 is bent toward the lock seat 30 along the sliding direction of the latch 20, and the lock seat 30 is provided with a second bending portion 31, which extends toward the latch 20 along a sliding direction perpendicular to the latch 20, and the end of the second bending portion 31 is bent toward the latch 20 along the sliding direction of the latch 20. The lock 20 slides relative to the box body 10 so that the bent end of the first bending portion 21 contacts the bent end of the second bending portion 31. At this time, along the arrangement direction of the two box bodies 10, the bent end of the first bending portion 21 abuts against the bent end of the second bending portion 31 to limit the displacement of the two box bodies 10 along the arrangement direction. The friction force between the first bending portion 21 and the second bending portion 31 is used to limit the displacement perpendicular to the arrangement direction of the two box bodies 10, thereby achieving the fixation of the two box bodies 10.

[0069] In another embodiment, the lock 20 is provided with a first bending portion 21, and the lock seat 30 is provided with a second bending portion 31. The direction perpendicular to the sliding direction of the lock 20 and perpendicular to the arrangement direction of the box body 10 is a first direction.

[0070] See also Figure 9-13 ,in Fig. 9 A partial schematic diagram of a combined box 100 in an unlocked state from a viewing angle provided in an embodiment of the present application is shown; Fig.10 A partial schematic diagram of a combined box 100 in an unlocked state from another viewing angle provided in an embodiment of the present application is shown; Fig.11 A partial cross-sectional schematic diagram of the combined box 100 in an unlocked state from another viewing angle provided in an embodiment of the present application is illustrated; Fig.12 A partial cross-sectional schematic diagram of a combined box 100 in an unlocked state provided in an embodiment of the present application; Fig.13 It is a partial cross-sectional schematic diagram of a combined box body 100 in an unlocked state provided in an embodiment of the present application.

[0071] In one embodiment, the latch 20 slides in a direction away from the lock base 30 so that the latch 20 and the lock base 30 are not engaged with each other, thereby achieving unlocking of the latch 20 and the lock base 30.

[0072] In one embodiment, if Figure 9-13 As shown, the first bent portion 21 and the second bent portion 31 both extend along the arrangement direction of the boxes 10 and are bent at the ends, the first bent portion 21 is bent toward the lock seat 30, and the second bent portion 31 is bent toward the latch 20. Along the sliding direction of the latch 20, the first bent portion 21 is not engaged with the second bent portion 31, and the bent end of the first bent portion 21 of one box 10 is not in contact with the bent end of the second bent portion 31 of the other box 10, so as to achieve unlocking of the latch 20 and the lock seat 30.

[0073] It can be understood that in one embodiment, the second part 202 of the lock 20 is exposed outside the box body 10, and the lock 20 can be made to slide relative to the box body 10 by driving the exposed second part 202, so that the first bending portion 21 and the second bending portion 31 are engaged with or separated from each other, thereby realizing locking or unlocking of the lock 20 and the lock seat 30.

[0074] In one embodiment, the lock 20 includes a first spring 40, which is connected to the body of the lock 20 and the extension portion 11. When the lock 20 slides away from the lock seat 30, the body of the lock 20 compresses the first spring 40. When the lock 20 and the lock seat 30 are locked with each other, the lock 20 is pushed out by the first spring 40. The first spring 40 is used to keep the lock 20 and the lock seat 30 locked with each other.

[0075] In one embodiment, if Figure 5-Figure 8 and Fig.13 As shown, along the sliding direction of the lock 20, the two ends of the first spring 40 of the lock 20 respectively abut the extension portion 11 and the first bending portion 21, and the first spring is used to drive the lock 20 to slide in the direction away from the extension portion 11 so that the first bending portion 21 and the second bending portion 31 are mutually engaged.

[0076] In one embodiment, the two ends of the first spring 40 in a box body 10 respectively abut against the extension portion 11 and the first bending portion 21. Figure 1 and Figure 2 , the other box 10 is located below the one box 10, and the lock seat 30 of the other box 10 extends into the inner cavity 12 of the one box 10. Along the arrangement direction of the two boxes 10, the first bent portion 21 and the second bent portion 31 at least partially overlap. By pressing the second portion 202 of the latch 20 exposed to one box 10, the first bent portion 21 is driven to slide toward the extension portion 11, so that the first spring 40 is compressed. At this time, along the sliding direction of the latch 20, the first bent portion 21 is located between the extension portion 11 and the second bent portion 31, leaving space for the lock seat 30 to extend. After the lock seat 30 extends into the inner cavity 12, the second portion 202 is released, and the first spring 40 pushes the first bent portion 21 to slide toward the second bent portion 31, so that the first bent portion 21 is engaged with the second bent portion 31, thereby achieving the locking of the latch 20 and the lock seat 30.

[0077] It can be understood that in this embodiment, pressing the second portion 202 to expose the box body 10 can drive the first bending portion 21 to move in a direction away from the second bending portion 31, so that the first bending portion 21 and the second bending portion 31 are spaced apart from each other, thereby achieving unlocking of the latch 20 and the lock seat 30.

[0078] In one embodiment, if Fig.12 As shown, the second part 202 of the lock 20 is slidably connected to the box 10, and the lock 20 is partially exposed to the outside of the box 10. By controlling the second part 202 of the lock 20 exposed outside the box 10, the lock 20 can be controlled, and then the lock 20 and the lock seat 30 can be locked or unlocked.

[0079] In one embodiment, if Fig.12As shown, the outer peripheral surface of the second part 202 of the lock 20 is provided with a step, and the step is used to form a supporting surface 22, and the supporting surface 22 faces the outside of the box body 10. The supporting surface 22 is used to abut against the inner peripheral surface of the inner cavity 12 to prevent the lock 20 from completely extending from the inner cavity 12 during the sliding process, resulting in failure of the connection between the lock 20 and the extension part 11.

[0080] In one embodiment, the latch 20 is of split design, that is, the first part 201 and the second part 202 are two parts, and the first part 201 and the second part 202 are spliced ​​and fixed to form the latch 20 to facilitate the assembly of the box 10.

[0081] In another embodiment, the first part 201 and the second part 202 are two parts, and the connection between the first part 201 and the second part 202 is detachable to facilitate maintenance of the box body 10 .

[0082] In another embodiment, if Figure 5-Figure 11 As shown, the first part 201 and the second part 202 of the latch 20 are integrally formed so that the second part 202 can drive the first part 201 to move. The integrally formed design improves the reliability of the connection between the second part 202 and the first part 201.

[0083] In some embodiments, the movable connection between the box body 10 and the latch 20 includes “a rotational connection between the box body 10 and the latch 20 ” to achieve mutual locking between the latch 20 and the lock seat 30 .

[0084] In one embodiment, one end of the first part 201 of the latch 20 is rotatably connected to the box 10 through the extension portion 11 , and the other end of the latch 20 is used to be mutually locked with a lock seat 30 of another box 10 .

[0085] In one embodiment, the extension portion 11 is rotatably connected to the box body 10 , and one end of the first portion 201 of the latch 20 is fixedly connected to the extension portion 11 .

[0086] In another embodiment, the extension portion 11 is fixedly connected to the box body 10 , and one end of the first portion 201 of the latch 20 is rotatably connected to the extension portion 11 .

[0087] In both of the above embodiments, the latch 20 can be connected to the box 10 by rotation. In one embodiment, the first portion 201 of the latch 20 of one box 10 includes a first bent portion 21, and the lock seat 30 of the other box 10 includes a second bent portion 31. Along the direction of the rotation axis of the first portion 201 of the latch 20, the first bent portion 21 and the second bent portion 31 are bent in opposite directions, and the latch 20 rotates relative to the box 10 so that the first bent portion 21 and the second bent portion 31 are mutually engaged.

[0088] In one embodiment, in a pair of mutually cooperating latches and lock seats 30, the rotation axis of the first part 201 of the latch 20 is perpendicular to the arrangement direction of the two boxes 10, and the first part 201 of the latch 20 is provided with a first bending portion 21, which extends in a direction perpendicular to the rotation axis of the first part 201, and the end of the first bending portion 21 is bent toward the lock seat 30 along the direction of the rotation axis of the first part 201, and the lock seat 30 is provided with a second bending portion 31, which extends toward the latch 20 in a direction perpendicular to the rotation axis of the first part 201, and the end of the second bending portion 31 is bent toward the latch 20 along the direction of the rotation axis of the first part 201.

[0089] It can be understood that along the arrangement direction of the two box bodies 10, the bent end of the first bending portion 21 at least partially overlaps with the bent end of the second bending portion, so that the two bent ends can contact and support each other to limit the displacement of the two box bodies 10 along the arrangement direction. The friction force between the first bending portion 21 and the second bending portion 31 is used to limit the displacement perpendicular to the arrangement direction of the two box bodies 10, thereby achieving the fixation of the two box bodies 10.

[0090] In one embodiment, if Fig.12 As shown, the outer peripheral surface of the second part 202 of the lock 20 is provided with a step, and the step is used to form a supporting surface 22, and the supporting surface 22 faces the outside of the box body 10. The supporting surface 22 is used to abut against the inner peripheral surface of the inner cavity 12 to limit the displacement of the lock 20 in the opposite direction along its rotation axis, thereby improving the connection strength between the box body 10 and the lock 20.

[0091] In the above-mentioned various embodiments, the box body 10 and the lock 20 can achieve mutual locking and unlocking of the lock 20 and the lock seat 30 by means of "sliding connection between the box body 10 and the lock 20" or "rotational connection between the box body 10 and the lock 20".

[0092] In one embodiment, the combined box 100 is placed on a platform, and a lock seat 30 is provided on the surface of the platform. The lock seat 30 extends into the inner cavity 12 of the box 10 at the bottom, so that the first part 201 of the lock 20 in the inner cavity 12 is locked with the lock seat 30 of the platform to fix the combined box 100 to the platform, which can reduce the displacement of the combined box 100 relative to the platform and protect the combined box 100.
