[0002] An emergency stop switch is usually installed on the box of an energy storage container, power distribution cabinet and the like, and in an accident state, the emergency stop switch can be pressed to shut down the operation of the device, thereby reducing the loss.

[0003] In order to avoid the operator from accidentally touching the emergency stop switch and isolating the rainwater from the outside when the device is normally operating, the emergency stop switch is usually installed in a glass cover which is fixed to the box by bolts. In an accident state, in order to press the emergency stop switch in time, the operator usually breaks the glass cover and then operates it, thereby causing waste of resources. CONTENT OF THE UTILITY MODEL

[0004] Therefore, embodiments of the present application aim to provide a box device, an energy storage device and a power distribution device which can at least partially solve the above problems.

[0005] A first aspect of embodiments of the present application provides a box device, comprising: a box for accommodating a battery device and / or a power distribution device; an emergency stop switch arranged in the box; and a shielding member capable of being operatively switched between a shielding state and an exposed state, in the shielding state, the shielding member shields the emergency stop switch, and in the exposed state, the emergency stop switch is exposed to the outer surface of the box.

[0006] The shielding member of the box device of the present embodiment can be operatively switched between the shielding state and the exposed state, and in an emergency, the operator can operate the shielding member to switch it to the exposed state, so that the emergency stop switch can be operated to stop the operation of the device, which is relatively convenient, and the shielding member can return to the shielding state after being switched to the exposed state, thereby realizing recycling and saving resources.

[0009] In some embodiments, the shielding member comprises a body and a connecting shaft, and the body is rotatably connected with the box by the connecting shaft.

[0010] In this embodiment, the main body is rotatably connected to the box body by means of a connecting shaft so that the shielding member can switch between the blocking state and the avoidance state. This connection method has a simple structure, low cost, and is easy to operate, thereby improving the efficiency of switching the shielding member between the blocking state and the avoidance state.

[0011] In some embodiments, one end of the body has a connecting hole, the connecting shaft is passed through the connecting hole and fixed to the box body, the connecting shaft is located on the top side of the emergency stop switch, and the extension direction of the connecting shaft intersects with the direction of gravity, and the body can rotate around the connecting shaft under the action of its own gravity.

[0012] In this embodiment, the shielding member can maintain the shielding state under the action of the body's own gravity, and can automatically reset from the avoidance state to the shielding state under the action of the body's own gravity. In this way, the risk of the shielding member remaining in the avoidance state due to operator error can be reduced.

The emergency stop switch is arranged in the mounting groove, and the bottom of the mounting groove points to the direction of the opening. The end of the emergency stop switch is located on the inside of the opening. In the blocking state, the blocking member covers the opening.

[0016] In this embodiment, the emergency stop switch is positioned within the mounting groove, thereby further reducing the probability of misoperation. Furthermore, the combination of the mounting groove and the shielding member further reduces the probability of external moisture, dust, etc. coming into contact with the emergency stop switch, thereby increasing the safety and service life of the emergency stop switch.

[0017] In some embodiments, the box body has a box door on one side along a first direction, the mounting groove is provided on the box door, and the first direction intersects with the direction of gravity.

[0018] In this embodiment, the mounting groove is set on the box door. It can be understood that the box door is usually set on the side that the operator is most likely to approach.

[0039] In some embodiments, the energy storage device is an energy storage container or an energy storage cabinet.

[0043] In some embodiments, the battery device can be a battery pack.

[0044] In some embodiments, the energy storage device can include a thermal management module, a master control module, a general control module, a power distribution device and a fire-fighting module, etc.

[0045] As an example, the thermal management module can include a liquid cooling unit that provides cooling liquid to each battery device through a pipeline for adjusting the temperature of the battery cell.

[0046] As an example, the master control module can serve as a battery management unit of the battery cluster for monitoring and managing the battery cluster.

[0048] As an example, the fire control system includes a control panel, a detector, an alarm device, and the like, for detecting, alarming, or extinguishing the energy storage system.

[0049] As an example, the power distribution device can be used to distribute power to the energy storage device power module.

[0050] The power distribution device can also be referred to as a power distribution box, a power distribution cabinet, and the like. The power distribution device is a modular device that realizes functions such as voltage conversion, circuit control, and power distribution, and can reasonably arrange and distribute circuits according to the needs of the energy storage system, thereby achieving the purpose of controlling and managing the energy storage system. The difference from the energy storage device is that the power distribution device itself can not include a battery device, but can be connected to an external power supply system, an external energy storage device, and the like to obtain power, and distribute the power to the power consumption device.

[0051] In some embodiments, the power distribution device includes a box device and a power distribution device arranged in the box device, and the power distribution device includes a wire harness, a wire harness collecting piece, a terminal, and the like.

[0052] An emergency stop switch is often provided on the box of the energy storage device or the power distribution device. In an accident state, the emergency stop switch can be pressed to emergency shut down the operation of the device to reduce losses.

[0053] In the related art, the emergency stop switch is often installed in a glass cover, and the glass cover is fixed to the box by bolts. It takes a long time to twist the bolts to remove the glass cover from the box to expose the emergency stop switch. Therefore, in an accident state, in order to press the emergency stop switch in time, the operator usually breaks the glass cover and then operates, which causes waste of resources.

[0054] In response to the above problems, a box device according to an embodiment of the present application is proposed, which can be applied to energy storage equipment or power distribution equipment. The box device according to the embodiment of the present application includes a box, an emergency stop switch and a shielding member. The box is used to accommodate a battery device and / or a power distribution device, the emergency stop switch is provided in the box, and the shielding member can be operably switched between a shielding state and an exposed state. In the shielding state, the shielding member shields the emergency stop switch, and in the exposed state, the emergency stop switch is exposed on the outer surface of the box.

[0055] The shielding member of the box device of this embodiment can be operably switched between a shielding state and an exposed state. In an emergency, the operator can operate the shielding member to switch it to the exposed state, so that the emergency stop switch can be operated to stop the equipment. The operation method is relatively convenient, and the shielding member can return to the shielding state after switching to the exposed state, thereby realizing reuse and saving resources.

[0056] Reference Figure 1-Figure 3 The housing 1 device of the embodiment of the present application includes a housing 1, an emergency stop switch 2, and a shielding member 3. The housing 1 is used to accommodate a battery device and / or a power distribution device. The emergency stop switch 2 is disposed in the housing 1. The shielding member 3 is operable to switch between a shielding state and an exposed state. In the shielding state, the shielding member 3 shields the emergency stop switch 2. In the exposed state, the emergency stop switch 2 is exposed on the outer surface of the housing 1.

[0057] The box 1 device of the embodiment of the present application can be applied to the energy storage device or power distribution device described in any of the above embodiments.

[0058] The specific structure of the box body 1 is not limited. As an example, the box body 1 can be a container or other box-type or cabinet-type structures.

[0059] The box 1 is used to accommodate a battery device and / or a power distribution device. The battery device and the power distribution device here can be the battery device and the power distribution device described in any of the above embodiments, and will not be repeated here.

[0060] An emergency stop switch 2 is disposed within the housing 1. When operated, the energy storage device and the power distribution device can be shut down. The specific structure of the emergency stop switch 2 is not limited, and may be a push-button switch (e.g., a toggle switch, a rotary switch, a touch switch, etc.). The emergency stop switch 2 may be electrically connected to a main control module of the energy storage device and the power distribution device, such that when operated, the energy storage device and the power distribution device can be shut down.

[0061] The specific structure of the shielding member 3 is not limited, as long as it can shield the emergency stop switch 2 in the shielding state. The emergency stop switch 2 herein can be understood as making the emergency stop switch 2 not exposed to the external environment, so that the probability of the operator accidentally touching the emergency stop switch 2 and causing the equipment to stop running unexpectedly during normal operation of the equipment can be reduced, and the problem of short circuit and reduced service life caused by contact between rainwater, dust and the like in the external environment and the emergency stop switch 2 can be prevented to some extent.

[0062] Figure 2 The shielding member 3 is in the avoiding state, and in this embodiment, the shielding member 3 can be operatively switched between the shielding state and the exposed state. The operatively switched between the shielding state and the exposed state herein can be understood as that the operator can operate the shielding member 3 to switch the shielding member 3 from the shielding state to the exposed state, or from the exposed state to the shielding state.

[0063] In the exposed state, referring to Figure 2 , the emergency stop switch 2 is exposed to the outer surface of the cabinet 1, so that the operator can touch and operate the emergency stop switch 2 to stop the operation of the energy storage equipment or power distribution equipment. As an example, in the exposed state, the shielding member 3 can be moved to another position relative to the cabinet 1 so as to no longer shield the emergency stop switch 2, and as another example, in the exposed state, the shielding member 3 can change shape so as to no longer shield the emergency stop switch 2.

[0064] The shielding member 3 of the cabinet 1 device of this embodiment can be operatively switched between the shielding state and the exposed state, and in an emergency, the operator can operate the shielding member 3 to switch it to the exposed state, so as to be able to operate the emergency stop switch 2 to stop the operation of the equipment, which is relatively convenient in operation mode, and the shielding member 3 can also return to the shielding state after being switched to the exposed state, realizing repeated use and saving resources.

[0065] In some embodiments, the shielding member 3 is movably connected with the cabinet 1 to switch between the shielding state and the exposed state by moving relative to the cabinet 1.

[0066] The specific way of movably connecting the shielding member 3 with the cabinet 1 is not limited, such as sliding connection or rotary connection, as long as the shielding member 3 can be moved to a position to expose the emergency stop switch 2 relative to the cabinet 1.

[0067] In this embodiment, the shielding member 3 is movably connected with the cabinet 1 to realize the switching of the shielding member 3 between the shielding state and the exposed state, so that the manufacturing cost of the cabinet 1 device can be reduced.

[0068] In some other embodiments, the shielding member 3 may be configured as a deformable structure, such as a retractable structure, a foldable structure, etc., and the shielding member 3 may be switched between a shielding state and an exposing state by deforming the shielding member 3 .

[0069] In some embodiments, reference Figure 2 and Figure 3 The shielding member 3 includes a main body 31 and a connecting shaft 32 , and the main body 31 is rotatably connected to the box body 1 through the connecting shaft 32 .

[0070] The specific structure and connection method of the body 31 and the connecting shaft 32 are not limited. As an example, refer to Figure 3 The main body 31 can be a sheet structure, a cover structure (for example, a structure in which the surface of one side facing the emergency stop switch 2 is recessed to form a cover cavity), etc. The main body 31 can have a connecting hole 31a, and the connecting shaft 32 can be passed through the above-mentioned connecting hole 31a and connected to the box body 1, so that the main body 31 is rotatably connected to the box body 1 through the connecting shaft 32.

[0071] exist Figure 2 and Figure 3 In the illustrated embodiment, the connecting hole 31a extends through the body 31 along the thickness direction of the body 31 (i.e., in a direction intersecting with the outer surface of the housing 1), and one end of the connecting shaft 32 passes through the connecting hole 31a and is fixed to the housing 1. In some other embodiments, the connecting hole 31a may also extend through the body 31 in a direction parallel to the outer surface of the housing 1. In this case, the connecting shaft 32 may be inserted into the connecting hole 31a, and the opposite ends of the connecting shaft 32 may be fixed to the outer surface of the housing 1.

[0072] by Figure 2 For example, the connecting shaft 32 may be a bolt or a screw, and the outer surface of the housing 1 may have a threaded hole, into which the connecting shaft 32 may be screwed, thereby facilitating the installation of the shielding member 3 to the housing 1. Of course, the connecting shaft 32 may also be connected to the housing 1 by welding, bonding, or the like, or the connecting shaft 32 may be formed as an integral structure with the housing 1.

[0073] In this embodiment, the main body 31 is rotatably connected to the box body 1 by means of the connecting shaft 32 so as to enable the shielding member 3 to switch between the blocking state and the avoidance state. This connection method has a simple structure, low cost, and is easy to operate, thereby improving the efficiency of switching the shielding member 3 between the blocking state and the avoidance state.

[0074] In some embodiments, reference Figure 2 and Figure 3The end of the main body 31 has a connecting hole 31a, the connecting shaft 32 is passed through the connecting hole 31a and is fixed to the box body 1, the connecting shaft 32 is located on the top side of the emergency stop switch 2, and the extension direction of the connecting shaft 32 intersects with the direction of gravity. The main body 31 can rotate around the connecting shaft 32 under the action of its own gravity.

[0075] As an example, the connecting shaft 32 may extend in a direction substantially perpendicular to the direction of gravity. The connecting shaft 32 and the connecting hole 31a may form a clearance fit, or the connecting shaft 32 may be configured to have a relatively smooth outer surface to reduce the damping between the connecting shaft 32 and the connecting hole 31a, thereby enabling the body 31 to rotate about the connecting shaft 32 under the action of its own gravity.

[0076] In the embodiment mentioned above where the connecting shaft 32 is a screw or a stud, the screw or stud can be partially screwed into the threaded hole to form a gap between the nut of the screw or stud and the main body 31, thereby allowing the main body 31 to rotate around the connecting shaft 32 under the action of its own gravity.

[0077] In this embodiment, refer to Figure 2 When not under external force, the body 31 naturally hangs down under its own weight. At this point, the majority of the body 31 is located below the connecting shaft 32, shielding the emergency stop switch 2, thereby maintaining the shielding member 3 in its shielding state. When subjected to an external force, the body 31 can rotate about the connecting shaft 32 in the direction of arrow R1, causing the shielding member 3 to switch to its retracted state. After the external force is removed, the body 31 can rotate about the connecting shaft 32 in the direction of arrow R2 under its own weight, returning to its naturally hanging state, thereby automatically resetting the shielding member 3 from its retracted state to its shielding state.

[0078] exist Figure 2 In the illustrated embodiment, the connecting shaft 32 extends in a direction substantially perpendicular to the outer surface of the housing. In other embodiments, as mentioned above, the connecting shaft 32 may extend in a direction substantially parallel to the outer surface of the housing. In such embodiments, the body 31 can rotate about the connecting shaft 32 in a direction away from the outer surface of the housing under the action of an external force, thereby switching the shielding member 3 to the avoidance state.

[0079] In this embodiment, the shielding member 3 can maintain the shielding state under the action of its own gravity of the main body 31, and can automatically reset from the avoidance state to the shielding state under the action of its own gravity. In this way, the risk of the shielding member 3 being in the avoidance state due to operator misoperation can be reduced.

[0080] In some embodiments, the body 31 is a transparent structure.

[0081] As an example, the body 31 may be made of glass or other transparent organic materials, so that the body 31 is formed into a transparent structure.

[0082] In the embodiment, the body 31 is transparent, so that the operator can directly observe the emergency stop switch 2 through the body 31 in the shielding state, and the operator can easily master the state of the emergency stop switch 2.

[0083] In some embodiments, referring to Figure 2 , the box 1 has a mounting groove 11, the mounting groove 11 forms an opening 11a on the outer surface of the box 1, the emergency stop switch 2 is arranged in the mounting groove 11, the end of the emergency stop switch 2 is located inside the opening 11a along the direction in which the bottom of the mounting groove 11 points to the opening 11a, and the shielding piece 3 covers the opening 11a in the shielding state.

[0084] In the embodiment, the specific shape of the mounting groove 11 is not limited, as long as the emergency stop switch 2 can be installed in the mounting groove 11. The shape of the shielding piece 3 can be substantially the same as that of the opening 11a, or can be different, as long as the shielding piece 3 can cover the opening 11a.

[0085] The bottom of the mounting groove 11 specifically refers to the side of the mounting groove 11 opposite to the opening 11a, along the direction in which the bottom of the mounting groove 11 points to the opening 11a, the end of the emergency stop switch 2 is located inside the opening 11a, that is, the emergency stop switch 2 does not protrude to the outside of the mounting groove 11, in other words, even in the exposed state, the emergency stop switch 2 does not protrude from the outer surface of the box 1, and the operator needs to put his hand into the mounting groove 11 from the opening 11a to operate the emergency stop switch 2.

[0086] As an example, along the above direction, the straight-line distance between the end of the emergency stop switch 2 and the plane of the opening 11a can be 2mm-5mm, such as 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. This distance range can effectively prevent accidental touch, and does not affect the operation efficiency of the operator when normally operating the emergency stop switch 2.

[0087] It should be noted that the above distance specifically refers to the distance measured when the emergency stop switch 2 is not operated (i.e., when the device is normally running).

[0088] In the embodiment, the emergency stop switch 2 is arranged in the mounting groove 11, so that the probability of misoperation can be further reduced. Moreover, the cooperation of the mounting groove 11 and the shielding piece 3 helps to further reduce the probability of contact between external water vapor, dust, etc. and the emergency stop switch 2, and improve the use safety and service life of the emergency stop switch 2.

[0089] In some embodiments, referring to Figure 1 , the box 1 has a box door 12 on one side along a first direction, the mounting groove 11 is arranged on the box door 12, and the first direction intersects the direction of gravity.

[0090] The door 12 is primarily used to open or close the box 1, thereby allowing an operator to install or remove a battery device, a power distribution device, or other control module into or from the box 1, or to enter or exit the box 1 for maintenance or other operations. The specific structure of the door 12 is not limited.

[0091] The door 12 is arranged on one side of the box body 1 along a first direction intersecting with the direction of gravity. Taking the box body 1 as a cubic structure as an example, the first direction can be the front-back direction of the box body 1, or the left-right direction, or any other suitable direction.

[0092] In this embodiment, the mounting groove 11 is set on the box door 12. It can be understood that the box door 12 is usually set on the side that the operator is most likely to approach. This helps the operator to quickly find the emergency stop switch 2 and operate it in an accident state, thereby improving operating efficiency.

[0093] Of course, in some other embodiments, the mounting groove 11 may also be provided at other positions of the box body 1 except the box door 12 .

[0094] In some embodiments, reference Figure 2 The box door 12 includes a bottom plate 122, a sealing plate 121 and a cylindrical member 123. The sealing plate 121 and the bottom plate 122 are spaced apart along the first direction. The opposite ends of the cylindrical member 123 in the axial direction are respectively connected to the sealing plate 121 and the bottom plate 122. The bottom plate 122 and the cylindrical member 123 are jointly arranged to form the mounting groove 11. The opening 11a is formed in the sealing plate 121, and the emergency stop switch 2 is connected to the bottom plate 122.

[0095] In this embodiment, the specific structure of the bottom plate 122 and the sealing plate 121 is not limited. The bottom plate 122 and the sealing plate 121 can be made of the same material or different materials. As an example, the periphery of the bottom plate 122 and / or the sealing plate 121 can have a folded edge, and the bottom plate 122 and the sealing plate 121 can be connected by the folded edge. Alternatively, the door 12 can include a frame structure, and the bottom plate 122 and the sealing plate 121 can be connected to the frame structure.

[0096] The cylindrical member 123 is specifically formed into a structure with both ends in the axial direction open. The two ends in the axial direction of the cylindrical body can be connected to the sealing plate 121 and the bottom plate 122 by means such as bonding or welding.

[0097] In this embodiment, the box door 12 includes a base plate 122 and a sealing plate 121 that are spaced apart, and a mounting groove 11 is formed in the box door 12 with the aid of a cylindrical member 123. Compared with the box door 12 being arranged as a solid plate body, this arrangement helps to reduce the overall weight and manufacturing cost of the box door 12.

[0098] The box 1 device will be described in more detail and specifically in connection with a specific embodiment below.

[0099] With reference to Figure 1-Figure 3 Embodiments of the present application provide a box 1 device which can be applied to energy storage equipment or power distribution equipment.

[0100] The box 1 device specifically comprises a box 1, an emergency stop switch 2 and a shielding piece 3. The box 1 is used to accommodate a battery device and a power distribution device, the emergency stop switch 2 is arranged in the box 1, and the shielding piece 3 can be operatively switched between a shielding state and an exposed state. In the shielding state, the shielding piece 3 shields the emergency stop switch 2, and in the exposed state, the emergency stop switch 2 is exposed to the outer surface of the box 1.

[0101] Specifically, the box 1 has a box door 12 on one side in a first direction, which is the front-rear direction of the box 1.

[0102] The box door 12 has a mounting groove 11 which forms an opening 11a on the outer surface of the box door 12. The emergency stop switch 2 is arranged in the mounting groove 11, and the end of the emergency stop switch 2 is located inside the opening 11a in the direction of the opening 11a along the groove bottom of the mounting groove 11, and the straight line distance from the opening 11a is 2-5 mm. In the shielding state, the shielding piece 3 covers the opening 11a.

[0103] The box door 12 specifically comprises a bottom plate 122, a cover plate 121 and a cylindrical piece 123. The cover plate 121 is arranged in the first direction and spaced apart from the bottom plate 122. The opposite ends of the cylindrical piece 123 in the axial direction are respectively connected to the cover plate 121 and the bottom plate 122. The bottom plate 122 and the cylindrical piece 123 jointly form the mounting groove 11. The opening 11a is formed in the cover plate 121, and the emergency stop switch 2 is connected to the bottom plate 122.

[0104] The shielding piece 3 comprises a body 31 and a connecting shaft 32. The body 31 is a transparent structure. The end of the body 31 has a connecting hole 31a which penetrates the body 31 in the thickness direction of the body 31. The connecting shaft 32 is arranged in the connecting hole 31a and fixed to the box 1. The connecting shaft 32 is located on the top side of the emergency stop switch 2, and the connecting shaft 32 extends in the first direction. The body 31 can rotate around the connecting shaft 32 under the action of its own gravity.

[0105] Under the action of no external force, the body 31 naturally falls under the action of its own gravity, so that the shielding piece 3 remains in the shielding state. When subjected to external force, the body 31 can rotate around the connecting shaft 32 in the direction away from the gravity, so that the shielding piece 3 remains in the avoiding state. After the external force is removed, the body 31 can rotate around the connecting shaft 32 under the action of its own gravity, and return to the naturally falling state, so that the shielding piece 3 is automatically reset from the avoiding state to the shielding state.

[0106] The connecting shaft 32 is specifically formed as a screw, and a threaded hole is formed on the sealing plate 121 of the box door 12. The screw is screwed into the threaded hole, and a gap is formed between the nut of the screw and the main body 31, that is, it is not fully tightened, so that the main body 31 can rotate around the screw under its own action.
