[0002] This disclosure is based on and claims priority to Chinese Patent Application No. 202422518847.0, filed on October 17, 2024, entitled “Container Device, Energy Storage Equipment and Power Distribution Equipment”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] Embodiments of this disclosure relate to the field of battery technology, and more particularly to an energy storage device. Background Technology

[0004] Emergency stop switches are often installed on the enclosures of equipment such as energy storage containers and power distribution cabinets. In the event of an accident, the emergency stop switch can be pressed to cut off the operation of the equipment in an emergency and reduce losses.

[0005] To minimize the risk of operators accidentally activating the emergency stop switch during normal equipment operation and to isolate it from external rainwater, the emergency stop switch is often installed in a glass enclosure. The glass enclosure is fixed to the housing with bolts. In the event of an accident, in order to press the emergency stop switch in time, the operator usually breaks the glass enclosure before operating the equipment, resulting in a waste of resources. Summary of the Invention

[0006] In view of this, the present disclosure aims to provide a housing device, energy storage device, and power distribution device that can at least partially solve the above-mentioned problems.

[0007] The first aspect of this disclosure provides a housing device, comprising: a housing for housing a battery device and / or a power distribution device; an emergency stop switch disposed in the housing; and a shielding member operable to switch between a shielded state and an exposed state, wherein in the shielded 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 housing.

[0008] The shielding component of the enclosure device in this embodiment can be operablely switched between a shielded state and an exposed state. In an emergency, the operator can operate the shielding component to switch it to the exposed state, thereby enabling the operation of the emergency stop switch to stop the equipment. The operation method is relatively convenient, and the shielding component can also return to the shielded state after switching to the exposed state, achieving reuse and saving resources.

[0009] In some embodiments, the shielding member is movably connected to the housing to switch between a shielded state and an exposed state by moving relative to the housing.

[0010] In this embodiment, the switching between the shielding component and the exposed state is achieved by the movable connection between the shielding component and the housing, which can reduce the manufacturing cost of the housing device.

[0011] In some embodiments, the shielding member includes a body and a connecting shaft, the body being rotatably connected to the housing via the connecting shaft.

[0012] In this embodiment, the main body is rotatably connected to the housing via a connecting shaft, thereby enabling the blocking component to switch between blocking and avoidance states. This connection method is simple in structure, low in cost, and easy to operate, improving the efficiency of the blocking component switching between blocking and avoidance states.

[0013] In some embodiments, one end of the main body has a connecting hole, a connecting shaft passes through the connecting hole and is fixed to the housing, 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, so that the main body can rotate around the connecting shaft under its own gravity.

[0014] In this embodiment, the blocking component can maintain the blocking state under the action of the body's own gravity, and can automatically reset from the avoidance state to the blocking state under the action of the body's own gravity. In this way, the risk of the blocking component being in the avoidance state due to operator error can be reduced.

[0015] In some embodiments, the connecting hole is configured as a threaded hole, and the connecting shaft is configured as a screw or stud.

[0016] In some embodiments, the extending direction of the connecting shaft is perpendicular to the outer surface of the housing, and the connecting hole penetrates the body along the thickness direction of the body.

[0017] In some embodiments, the extending direction of the connecting shaft is parallel to the outer surface of the housing, and the opposite ends of the connecting shaft extend from the connecting hole and are fixed to the outer surface of the housing.

[0018] In some embodiments, the body is a transparent structure.

[0019] In this embodiment, the main body is a transparent structure, so that the operator can directly observe the emergency stop switch through the main body when it is covered, making it easier for the operator to grasp the status of the emergency stop switch.

[0020] In some embodiments, the housing has a mounting groove, the outer surface of the mounting groove housing forms an opening, an emergency stop switch is disposed in the mounting groove, the emergency stop switch is located in the direction of the opening along the bottom of the mounting groove, the end of the emergency stop switch is located inside the opening, and in the blocking state, the blocking member covers the opening.

[0021] In this embodiment, the emergency stop switch is installed within the mounting slot, thereby further reducing the probability of accidental operation. Furthermore, the combination of the mounting slot and the shielding component helps to further reduce the probability of external moisture, dust, etc., coming into contact with the emergency stop switch, improving its safety and service life.

[0022] In some embodiments, the straight-line distance between the end of the emergency stop switch and the plane containing the opening is 2-5 mm along the direction from the bottom of the mounting groove to the opening.

[0023] In some embodiments, the housing has a door on one side along a first direction, and a mounting groove is disposed on the door, the first direction intersecting the direction of gravity.

[0024] In this embodiment, the mounting slot is placed on the door of the enclosure. It can be understood that the door is usually placed on the side that is most easily accessible to the operator. This helps the operator to quickly find and operate the emergency stop switch in the event of an accident, thereby improving operational efficiency.

[0025] In some embodiments, the door includes a bottom plate, a sealing plate, and a cylindrical member. The sealing plate and the bottom plate are spaced apart along a first direction. The opposite ends of the cylindrical member in the axial direction are respectively connected to the sealing plate and the bottom plate. The bottom plate and the cylindrical member together form a mounting groove. An opening is formed in the sealing plate. An emergency stop switch is connected to the bottom plate.

[0026] In this embodiment, the door includes a base plate and a sealing plate spaced apart, and a mounting groove is formed in the door by means of a cylindrical member. Compared with the door being a solid plate, this arrangement helps to reduce the overall weight and manufacturing cost of the door.

[0027] In some embodiments, the two ends of the cylindrical member are welded to the end plate and the bottom plate respectively in the axial direction.

[0028] A second aspect of the present disclosure provides an energy storage device, which includes: a housing device according to the first aspect of the present disclosure; and a battery device disposed within the housing.

[0029] A third aspect of the present disclosure provides a power distribution device, which includes: a housing device according to the first aspect of the present disclosure; and a power distribution device disposed within the housing.

[0046] The enclosure device of this disclosure is applied to energy storage equipment or power distribution equipment.

[0047] Energy storage devices can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. Energy storage devices can store electrical energy as needed and output it when appropriate. For example, energy storage devices can store electrical energy during off-peak hours and provide power to relevant users or electrical equipment during peak hours. The energy storage system provided in this disclosure embodiment can be any power system that requires energy storage devices.

[0048] In some embodiments, the energy storage device is an energy storage container or an energy storage cabinet.

[0049] In some embodiments, the energy storage device may include a housing and one or more battery clusters housed within the housing.

[0050] A battery cluster may include multiple battery units, which are connected in series via a busbar to increase the voltage of the energy storage device. When the energy storage device includes multiple battery clusters, the battery clusters are connected in parallel to increase the capacity of the energy storage device.

[0051] A battery device may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connections via a busbar.

[0052] In some embodiments, the battery device may be a battery pack.

[0053] In some embodiments, the energy storage device may include modules such as a thermal management module, a main control module, a central control module, a power distribution device, and a fire protection module.

[0054] As an example, the thermal management module may include a liquid cooling unit that supplies coolant to each battery device via piping to regulate the temperature of the individual battery cells.

[0055] As an example, the main control module can serve as the battery management unit for the battery cluster, configured to monitor and manage the battery cluster. The main control module can monitor information such as the current, voltage, power, or temperature of the battery cluster. For instance, it can control the charging and discharging current and voltage of the battery cluster. The main control module includes auxiliary battery management units, integrated switches, and other modules.

[0056] As an example, the central control module can serve as the battery management unit for an energy storage device, configured to monitor and manage the device. The central control module can monitor information such as the energy storage device's current, voltage, power, state of charge, or temperature. For instance, it can control the charging and discharging current and voltage of the energy storage device. As an example, the central control module includes modules such as an insulation monitoring module, a main battery management unit, and Ethernet and fiber optic conversion modules.

[0057] As an example, a fire protection system includes control panels, detectors, alarm devices, etc., used to detect, alarm, or extinguish fires in energy storage systems.

[0058] As an example, the power distribution unit can be used to distribute power to the power modules of energy storage devices.

[0059] Power distribution equipment, also known as distribution boxes or cabinets, is a modular device that performs functions such as voltage conversion, circuit control, and power distribution. It allows for the rational arrangement and allocation of circuits according to the needs of an energy storage system, thereby achieving the purpose of controlling and managing the energy storage system. The difference between power distribution equipment and energy storage devices is that power distribution equipment itself may not include battery devices; instead, it connects to an external power supply system or external energy storage device to obtain electrical energy and distribute it to the user equipment.

[0060] In some embodiments, the power distribution equipment includes a housing and a power distribution device disposed within the housing, the power distribution device including a wiring harness, a wiring harness collection component, a terminal block, etc.

[0061] Emergency stop switches are often installed on the enclosures of energy storage or power distribution equipment. In the event of an accident, pressing the emergency stop switch can immediately cut off the operation of the equipment and reduce losses.

[0062] In related technologies, emergency stop switches are often installed in glass enclosures, which are fixed to the housing with bolts. It takes a long time to remove the glass enclosure from the housing by turning the bolts to expose the emergency stop switch. Therefore, in the event of an accident, in order to press the emergency stop switch in time, the operator usually breaks the glass enclosure before operating, which results in a waste of resources.

[0063] To address the aforementioned problems, a housing device according to an embodiment of this disclosure is proposed. This housing device can be applied to energy storage devices or power distribution equipment. The housing device according to an embodiment of this disclosure includes a housing, an emergency stop switch, and a shielding member. The housing is used to house a battery device and / or a power distribution device. The emergency stop switch is disposed in the housing. The shielding member is operable to switch between a shielded state and an exposed state. In the shielded state, the shielding member shields the emergency stop switch; in the exposed state, the emergency stop switch is exposed on the outer surface of the housing.

[0064] The shielding component of the enclosure device in this embodiment can be operablely switched between a shielded state and an exposed state. In an emergency, the operator can operate the shielding component to switch it to the exposed state, thereby enabling the operation of the emergency stop switch to stop the equipment. The operation method is relatively convenient, and the shielding component can also return to the shielded state after switching to the exposed state, achieving reuse and saving resources.

[0065] Referring to Figures 1-3, the enclosure device 100 of this embodiment includes an enclosure 1, an emergency stop switch 2, and a shielding member 3. The enclosure 1 is used to house a battery device and / or a power distribution device. The emergency stop switch 2 is disposed in the enclosure 1. The shielding member 3 is operable to switch between a shielded state and an exposed state. In the shielded 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 enclosure 1.

[0066] The enclosure device 100 of this disclosure can be applied to energy storage devices or power distribution devices as described in any of the above embodiments.

[0067] The specific structure of container 1 is not limited. For example, container 1 can be a shipping container or other box-type or cabinet-type structures, etc.

[0068] The housing 1 is used to house the battery device and / or power distribution device, which can be the battery device and power distribution device described in any of the above embodiments, and will not be repeated here.

[0069] Emergency stop switch 2 is installed in enclosure 1. When activated, emergency stop switch 2 can stop the operation of energy storage equipment and power distribution equipment. The specific structure of emergency stop switch 2 is not limited; it can be a push-button switch, toggle switch, rotary switch, touch switch, etc. Emergency stop switch 2 can be electrically connected to the main control module of energy storage equipment and power distribution equipment, so that when activated, it can stop the operation of energy storage equipment and power distribution equipment.

[0070] The specific structure of the shielding component 3 is not limited, as long as it can shield the emergency stop switch 2 when in the shielding state. Here, shielding the emergency stop switch 2 can be understood as preventing the emergency stop switch 2 from being exposed to the external environment. In this way, the probability of the equipment stopping unexpectedly due to the operator accidentally touching the emergency stop switch 2 during normal operation can be reduced, and it can also prevent rainwater, dust, etc. in the external environment from coming into contact with the emergency stop switch 2, thus preventing problems such as short circuits and reduced service life.

[0071] In Figure 2, the shielding component 3 is in an avoidance state. In this embodiment, the shielding component 3 can be operablely switched between a shielding state and an exposed state. Operable switching between the shielding and exposed states here can be understood as the operator being able to switch the shielding component 3 from a shielding state to an exposed state, or vice versa, by manipulating the shielding component 3.

[0072] In the exposed state, referring to Figure 2, the emergency stop switch 2 is exposed on the outer surface of the enclosure 1, allowing the operator to reach and operate the emergency stop switch 2 to stop the energy storage device or power distribution equipment. As an example, in the exposed state, the blocking member 3 can be moved to another position relative to the enclosure 1, thus preventing it from continuing to block the emergency stop switch 2. As another example, in the exposed state, the blocking member 3 can change shape to prevent it from continuing to block the emergency stop switch 2.

[0073] The shielding member 3 of the enclosure device 100 in this embodiment can be operablely switched between a shielding state and an exposed state. In an emergency, the operator can operate the shielding member 3 to switch it to the exposed state, thereby enabling the operation of the emergency stop switch 2 to stop the equipment from running. The operation method is relatively convenient, and the shielding member 3 can also return to the shielding state after switching to the exposed state, so it can be reused and save resources.

[0074] In some embodiments, the shielding member 3 is movably connected to the housing 1 to switch between a shielded state and an exposed state by moving relative to the housing 1.

[0075] The specific way in which the shielding part 3 is movably connected to the housing 1 is not limited. It can be a sliding connection or a rotating connection, as long as the shielding part 3 can move relative to the housing 1 to a position that exposes the emergency stop switch 2.

[0076] In this embodiment, the shielding member 3 is switched between a shielding state and an exposed state by being movably connected to the housing 1, which can reduce the manufacturing cost of the housing device 100.

[0077] In some other embodiments, the shielding member 3 can be configured as a deformable structure, such as a stretchable structure, a foldable structure, etc., and can be switched between a shielding state and an exposed state by deforming the shielding member 3.

[0078] In some embodiments, referring to Figures 2 and 3, the shielding member 3 includes a body 31 and a connecting shaft 32, and the body 31 is rotatably connected to the housing 1 through the connecting shaft 32.

[0079] The specific structure and connection method of the body 31 and the connecting shaft 32 are not limited. As an example, referring to Figure 3, the body 31 can be a sheet structure, a cover structure (for example, a structure in which the surface facing the emergency stop switch 2 is recessed to form a cover cavity), etc. The body 31 can have a connecting hole 31a. The connecting shaft 32 can pass through the connecting hole 31a and be connected to the housing 1, thereby realizing the rotational connection between the body 31 and the housing 1 through the connecting shaft 32.

[0080] In the embodiments shown in Figures 2 and 3, the connecting hole 31a extends through the body 31 along its thickness direction (i.e., the 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 pass through the connecting hole 31a, and the opposite ends of the connecting shaft 32 may be fixed to the outer surface of the housing 1.

[0081] Taking the connection method shown in Figure 2 as an example, the connecting shaft 32 can be a bolt or screw, and the outer surface of the housing 1 can have a threaded hole. The connecting shaft 32 can be screwed into the threaded hole, which facilitates the installation of the shielding part 3 to the housing 1. Of course, the connecting shaft 32 can also be connected to the housing 1 by means of welding, bonding, etc., or the connecting shaft 32 can be formed into an integral structure with the housing 1.

[0082] In this embodiment, the main body 31 is rotatably connected to the housing 1 by means of the connecting shaft 32, thereby realizing the switching of the blocking component 3 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 the blocking component 3 in switching between the blocking state and the avoidance state.

[0083] In some embodiments, referring to Figures 2 and 3, the end of the body 31 has a connecting hole 31a, the connecting shaft 32 passes through the connecting hole 31a and is fixed to the housing 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 the direction of gravity, so that the body 31 can rotate around the connecting shaft 32 under its own gravity.

[0084] As an example, the extension direction of the connecting shaft 32 can be approximately perpendicular to the direction of gravity. The connecting shaft 32 and the connecting hole 31a can form a clearance fit, or the connecting shaft 32 can 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 around the connecting shaft 32 under its own gravity.

[0085] In the embodiment where the connecting shaft 32 mentioned above is a screw or stud, the screw or stud can be partially screwed into the threaded hole, so that a gap is formed between the nut of the screw or stud and the body 31, thereby allowing the body 31 to rotate around the connecting shaft 32 under its own weight.

[0086] In this embodiment, referring to Figure 2, when no external force is applied, the main body 31 will naturally hang down under its own weight. At this time, most of the structure of the main body 31 will be located below the connecting shaft 32 and block the emergency stop switch 2, thereby keeping the blocking member 3 in the blocking state. When an external force is applied, the main body 31 can rotate around the connecting shaft 32 in the direction of arrow R1 in the figure, causing the blocking member 3 to switch to the avoidance state. After the external force is removed, the main body 31 can rotate around the connecting shaft 32 in the direction of arrow R2 in the figure under its own weight, returning to the naturally hanging state, thereby automatically resetting the blocking member 3 from the avoidance state to the blocking state.

[0087] In the embodiment shown in Figure 2, the extension direction of the connecting shaft 32 is approximately perpendicular to the outer surface of the housing. In some other embodiments, as mentioned above, the extension direction of the connecting shaft 32 may be approximately parallel to the outer surface of the housing. In this embodiment, the body 31 can rotate around 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 blocking member 3 to the avoidance state.

[0088] In this embodiment, the shielding member 3 can maintain the shielding state under the action of the body 31's own gravity, and can automatically reset from the avoidance state to the shielding state under the action of the body 31's own gravity. In this way, the risk of the shielding member 3 being in the avoidance state due to operator error can be reduced.

[0089] In some embodiments, the body 31 is a transparent structure.

[0090] As an example, the body 31 can be made of glass or other transparent organic materials, thereby forming a transparent structure.

[0091] In this embodiment, the main body 31 is a transparent structure, so that the operator can directly observe the emergency stop switch 2 through the main body 31 when it is covered, making it easier for the operator to grasp the status of the emergency stop switch 2.

[0092] In some embodiments, referring to FIG2, the housing 1 has a mounting groove 11, the mounting groove 11 forms an opening 11a on the outer surface of the housing 1, the emergency stop switch 2 is disposed in the mounting groove 11, pointing in the direction from the bottom of the mounting groove 11 to the opening 11a, the end of the emergency stop switch 2 is located inside the opening 11a, and in the blocking state, the blocking member 3 covers the opening 11a.

[0093] In this 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 member 3 can be approximately the same as or different from the shape of the opening 11a, as long as the shielding member 3 can cover the opening 11a.

[0094] The bottom of the mounting groove 11 specifically refers to the side of the mounting groove 11 opposite to the opening 11a. Along the bottom of the mounting groove 11 pointing towards 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 outside the mounting groove 11. In other words, even in the exposed state, the emergency stop switch 2 will not protrude from the outer surface of the housing 1. The operator needs to put his hand into the mounting groove 11 through the opening 11a to operate the emergency stop switch 2.

[0095] As an example, along the aforementioned direction, the straight-line distance between the end of the emergency stop switch 2 and the plane containing the opening 11a can be 2mm to 5mm, such as 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. This distance range can effectively prevent accidental activation without affecting the operating efficiency of the operator when operating the emergency stop switch 2 normally.

[0096] It should be noted that the above distance specifically refers to the distance measured when the emergency stop switch 2 is not in operation (i.e., when the equipment is running normally).

[0097] In this embodiment, the emergency stop switch 2 is installed in the mounting slot 11, which further reduces the probability of misoperation. Furthermore, the cooperation between the mounting slot 11 and the shielding member 3 helps to further reduce the probability of external moisture, dust, etc., coming into contact with the emergency stop switch 2, thereby improving the safety and service life of the emergency stop switch 2.

[0098] In some embodiments, referring to FIG1, the housing 1 has a door 12 on one side along a first direction, and a mounting groove 11 is disposed on the door 12. The first direction intersects the gravity direction.

[0099] The door 12 is mainly used to open or close the enclosure 1, thereby allowing operators to install or remove battery devices, power distribution devices, or other control modules into or from the enclosure 1, or to allow operators to enter or exit the enclosure 1 for maintenance or other operations. The specific structure of the door 12 is not limited.

[0100] The door 12 is located on one side of the box body 1 along a first direction, which intersects 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, the left-right direction, or any other suitable direction of the box body 1.

[0101] In this embodiment, the mounting slot 11 is set in the door 12. It can be understood that the door 12 is usually set on the side that is most easily accessible to the operator. This helps the operator to quickly find the emergency stop switch 2 and operate it in case of an accident, thus improving operating efficiency.

[0102] Of course, in some other embodiments, the mounting slot 11 may also be located in other positions on the housing 1 besides the door 12.

[0103] In some embodiments, referring to FIG2, the 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 a 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 together form a mounting groove 11. An opening 11a is formed in the sealing plate 121. An emergency stop switch 2 is connected to the bottom plate 122.

[0104] In this embodiment, the specific structure of the base plate 122 and the sealing plate 121 is not limited.

[0106] In this embodiment, the door 12 includes a base plate 122 and a sealing plate 121 spaced apart, and a mounting groove 11 is formed in the door 12 by means of a cylindrical member 123. Compared with the door 12 being a solid plate, this arrangement helps to reduce the overall weight and manufacturing cost of the door 12.

[0107] The enclosure device 100 involved in one or more of the above embodiments will be described in more detail below with reference to a specific embodiment.

[0108] Referring to Figures 1-3, embodiments of this disclosure provide a housing device 100, which can be applied to energy storage devices or power distribution devices.

[0109] The enclosure device 100 specifically includes an enclosure 1, an emergency stop switch 2, and a shielding member 3. The enclosure 1 is used to house the battery device and the power distribution device. The emergency stop switch 2 is disposed in the enclosure 1. The shielding member 3 can be operablely switched between a shielded state and an exposed state. In the shielded 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 enclosure 1.

[0110] Specifically, the box 1 has a door 12 on one side along a first direction, which is the front-to-back direction of the box 1.

[0111] The door 12 has a mounting groove 11, which forms an opening 11a on the outer surface of the door 12. An emergency stop switch 2 is disposed in the mounting groove 11, pointing from the bottom of the mounting groove 11 towards the opening 11a. The end of the emergency stop switch 2 is located inside the opening 11a, and the straight distance between it and the plane of the opening 11a is 2mm-5mm. In the blocked state, the blocking member 3 covers the opening 11a.

[0112] The door 12 specifically 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 a first direction. The two 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 together form an installation groove 11. An opening 11a is formed in the sealing plate 121. An emergency stop switch 2 is connected to the bottom plate 122.

[0113] The shielding component 3 includes a body 31 and a connecting shaft 32. The body 31 is transparent and has a connecting hole 31a at one end. The connecting hole 31a extends through the body 31 along its thickness direction. The connecting shaft 32 passes through the connecting hole 31a and is fixed to the housing 1. The connecting shaft 32 is located on the top side of the emergency stop switch 2 and extends along a first direction. The body 31 can rotate around the connecting shaft 32 under its own weight.

[0114] When no external force is applied, the main body 31 hangs naturally under its own weight, thus keeping the blocking member 3 in the blocking state. When an external force is applied, the main body 31 can rotate around the connecting shaft 32 in a direction opposite to gravity, keeping the blocking member 3 in the avoidance state. After the external force is removed, the main body 31 can rotate around the connecting shaft 32 under its own weight, returning to the naturally hanging state, thus automatically resetting the blocking member 3 from the avoidance state to the blocking state.

[0115] The connecting shaft 32 is specifically formed as a screw. A threaded hole is formed on the sealing plate 121 of the box door 12. The screw is screwed into the threaded hole, and there is a gap between the screw nut and the body 31, that is, it is not fully tightened, so that the body 31 can rotate around the screw under its own action.
