[0002] This application claims priority to Chinese Patent Application No. 2024105085724, filed on April 25, 2024, entitled “Electrical Device and Control Method Thereof”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of battery technology, and more specifically, to an electrical device and its control method. Background Technology

[0004] With social and economic development and the increasing awareness of environmental protection and energy conservation, new energy vehicles are gaining wider acceptance. Currently, new energy vehicles typically use dual-pack or multi-pack systems, meaning they are equipped with multiple batteries. To facilitate quick battery swapping, quick-swap connectors are commonly used to connect each battery pack to the vehicle's electrical system, as well as to the water system. The connector plug and connector are attached to the battery and the vehicle body, respectively. However, in existing dual-pack or multi-pack systems, when operating with fewer batteries (i.e., under different usage conditions), only a small number of batteries may be installed. This leaves connectors in areas where no batteries are installed exposed, making them susceptible to damage and resulting in higher operating costs for the electrical system.

[0005] Summary of the Invention

[0006] This application provides an electrical device and its control method, which can effectively reduce the later use cost of the electrical device.

[0007] In a first aspect, embodiments of this application provide an electrical device, including a mounting base, a first connector, and a sealing mechanism; the first connector is mounted on the mounting base and has a first socket, the first connector being used for electrical or fluid connection with a battery; the sealing mechanism includes a drive unit and a sealing assembly, the drive unit is mounted on the mounting base, the sealing assembly is connected to the drive unit, and the drive unit is configured to drive the sealing assembly to move relative to the mounting base to seal or open the first socket.

[0008] In the above technical solution, the electrical device is provided with a first connector for electrical or fluid connection with a battery, so as to realize the electrical connection between the battery and the electrical system of the electrical device or the water circuit connection of the cooling system. By providing a sealing mechanism on the electrical device, the sealing mechanism includes a drive unit and a sealing component. The drive unit is mounted on the mounting base of the electrical device, so that the drive unit can drive the sealing component to move relative to the mounting base, thereby causing the sealing component to seal or open the first socket of the first connector, thus sealing the first connector. The electrical device with this structure can achieve electrical connection through the sealing mechanism. The automatic sealing of the exposed first connector on the power device during battery operation reduces the likelihood of the first connector being exposed, thus mitigating the risk of impurities or particles from the external environment entering the first connector and reducing the subsequent operating costs of the power device. Furthermore, the automatic sealing of the first connector without manual intervention improves the automation level of battery swapping, reduces the failure rate caused by manual operation, and ultimately improves the battery swapping efficiency and reduces the cost of battery swapping.

[0009] In some embodiments, the drive unit includes a first drive member; the first drive member is mounted on a mounting base, the first drive member is connected to a blocking assembly, and the first drive member is configured to drive the blocking assembly to move along a first direction to block or open the first socket.

[0010] In the above technical solution, the driving unit is provided with a first driving component, and the first driving component can drive the blocking component to move relative to the mounting base along a first direction, so as to block or open the first socket of the first connector by moving the blocking component along the first direction. The blocking mechanism with this structure is convenient for the blocking component to block the first socket of the first connector, which helps to reduce the difficulty of the blocking component to block the first socket of the first connector. The structure is simple and easy to implement. On the other hand, it can effectively improve the stability and reliability of the blocking component in blocking the first socket of the first connector.

[0011] In some embodiments, the driving unit further includes a second driving member; the second driving member is connected to the output end of the first driving member, the first driving member is configured to drive the second driving member to move along a first direction, the blocking component is connected to the output end of the second driving member, and the second driving member is configured to drive the blocking component to rotate about an axis extending along the first direction between a first position and a second position; when the blocking component is in the first position, the first driving member can drive the blocking component to move along the first direction and block the first socket; when the blocking component is in the second position, the projection of the first socket in the first direction does not overlap with the blocking component.

[0012] In the above technical solution, the driving unit is further provided with a second driving member, which can drive the sealing component to rotate relative to the mounting base around an axis extending along the first direction, so that the sealing component can switch between a first position and a second position. When the sealing component is in the first position, it only needs to move along the first direction under the drive of the first driving member to seal or open the first socket of the first connector. When the sealing component is in the second position, it can also ensure that the projection of the sealing component and the first socket of the first connector in the first direction do not overlap, so that the sealing component can avoid the first socket of the first connector. Therefore, the battery can be reassembled in the battery-operated area without disassembling the sealing mechanism. The operation is simple and can improve the convenience of battery swapping, which is conducive to further improving the battery swapping efficiency of the power device and further reducing the battery swapping cost of the power device.

[0013] In some embodiments, along a first direction, the second drive member and the blocking assembly are located on opposite sides of the mounting base; the blocking mechanism further includes an elastic member, along the first direction, the elastic member is compressed between the second drive member and the mounting base, and both ends of the elastic member abut against the second drive member and the mounting base, respectively.

[0014] In the above technical solution, the second driving member and the sealing component are respectively disposed on both sides of the mounting base along the first direction, and an elastic member is also disposed between the second driving member and the mounting base. The elastic member is disposed between the second driving member and the mounting base in a compressed state, so that the second driving member tends to move away from the mounting base along the first direction under the elastic force of the elastic member. This allows the elastic member to keep the sealing component in the position of sealing the first socket. The sealing mechanism with this structure can continue to keep the sealing component in the state of sealing the first socket by the elastic member when the first driving member fails, so as to alleviate the phenomenon of the sealing component accidentally disengaging from the first socket when the first driving member fails. This enables the sealing mechanism to have a double insurance function, which is conducive to further improving the stability and reliability of the sealing mechanism in sealing the first socket of the first connector.

[0015] In some embodiments, the blocking mechanism further includes a connecting shaft; the connecting shaft passes through the mounting base in a first direction, and the connecting shaft connects to the output end of the blocking assembly and the second drive member; wherein an elastic element is sleeved on the outside of the connecting shaft.

[0016] In the above technical solution, the sealing mechanism is further provided with a connecting shaft passing through the mounting base in the first direction. The connecting shaft is connected to the sealing components and the second driving component located on both sides of the mounting base, so that the driving unit can drive the sealing components to move relative to the mounting base. By sleeved on the outside of the connecting shaft, and with the two ends of the elastic element abutting against the second driving component and the mounting base in the first direction, the difficulty of assembling the elastic element between the second driving component and the mounting base can be reduced, and the stability of the elastic element assembly between the second driving component and the mounting base can be improved. On the other hand, the connecting shaft can play a certain guiding role for the elastic element, so that the elastic element can deform stably in the first direction. This enables the elastic element to provide a relatively stable elastic force to the second driving component in the first direction to move away from the mounting base, so as to keep the sealing component in the position of sealing the first socket.

[0017] In some embodiments, the sealing assembly includes a first sealing member for sealing a first socket; wherein, a first clearance groove is provided on the side of the mounting base facing the sealing assembly in a first direction, and when the sealing assembly is in a second position, the first sealing member and the first clearance groove are disposed opposite to each other along the first direction, and the first clearance groove is used to accommodate at least a portion of the first sealing member.

[0018] In the above technical solution, the sealing assembly is provided with a first sealing member for sealing the first socket. By providing a first clearance groove on the side of the mounting base facing the sealing assembly in the first direction, and when the sealing assembly is in the second position, the first sealing member of the sealing assembly can be arranged opposite to the first clearance groove in the first direction. This allows the first driving member of the driving unit to drive the sealing assembly in the second position to move in the first direction toward the mounting base, so that at least a part of the first sealing member can be accommodated in the first clearance groove. This reduces the space occupied by the sealing assembly on the side of the mounting base for battery assembly in the first direction, which is beneficial to further reduce the interference between the sealing assembly and the battery when reassembling the battery in the area where the battery is depleted, thus facilitating battery reassembly.

[0019] In some embodiments, along a first direction, a first protrusion is formed on the side of the mounting base opposite to the sealing assembly and corresponding to the position of the first clearance groove.

[0020] In the above technical solution, by forming a first protrusion on the side of the mounting base away from the sealing component along the first direction and at the position corresponding to the first clearance groove, the first clearance groove is a structure that can be formed on the mounting base by a stamping process, which helps to reduce the difficulty of forming the first clearance groove on the mounting base and improves the processing efficiency of the first clearance groove.

[0021] In some embodiments, the electrical device further includes a second connector having a second socket for fluid connection with a battery, and a first connector for electrical connection with a battery; wherein, the driving unit is configured to drive the sealing assembly to simultaneously seal the first socket and the second socket or simultaneously open the first socket and the second socket; when the sealing assembly is in a first position, the first driving member can drive the sealing assembly to move along a first direction and seal the first socket and the second socket; when the sealing assembly is in a second position, the projections of the first socket and the second socket in the first direction do not overlap with the sealing assembly.

[0022] In the above technical solution, the electrical device is also equipped with a second connector. The second connector and the first connector are used for fluid connection and electrical connection with the battery, respectively, so as to realize the electrical connection between the battery and the electrical system of the electrical device and the water circuit of the cooling system. The driving unit can drive the sealing component to simultaneously seal or open the first socket of the first connector and the second socket of the second connector, thereby achieving simultaneous sealing of the first connector and the second connector. On the one hand, the sealing mechanism protects both the first connector and the second connector, reducing the risk of damage to both connectors. On the other hand, it further reduces manual intervention, achieving automatic sealing of the first connector and the second connector of the electrical device without manual intervention, thereby improving the automation level of battery swapping of the electrical device. Furthermore, the second driving member can drive the sealing assembly to rotate relative to the mounting base around an axis extending along the first direction, allowing the sealing assembly to switch between a first position and a second position. When the sealing assembly is in the first position, it only needs to move along the first direction under the drive of the first driving member to seal or open the first and second sockets. When the sealing assembly is in the second position, its projections in the first direction do not overlap with those of the first and second sockets, allowing the sealing assembly to avoid the first and second sockets. This eliminates the need to disassemble the sealing mechanism to reassemble the battery in the battery-operated area, simplifying the operation and improving the convenience of battery swapping, thus further enhancing the battery swapping efficiency of the power supply device.

[0023] In some embodiments, the sealing assembly includes a second sealing member for sealing the second socket; wherein, the mounting base is provided with a second clearance groove on the side facing the sealing assembly in a first direction, and when the sealing assembly is in a second position, the second sealing member and the second clearance groove are disposed opposite to each other in the first direction, and the second clearance groove is used to accommodate at least a portion of the second sealing member.

[0024] In the above technical solution, the sealing assembly is provided with a second sealing member for sealing the second socket. By providing a second clearance groove on the side of the mounting base facing the sealing assembly in the first direction, and when the sealing assembly is in the second position, the second sealing member of the sealing assembly can be arranged opposite to the second clearance groove in the first direction. This allows the first driving member of the driving unit to drive the sealing assembly in the second position to move in the first direction toward the mounting base, so that at least a part of the first sealing member can be accommodated in the first clearance groove and at least a part of the second sealing member can be accommodated in the second clearance groove. This reduces the space occupied by the sealing assembly on the side of the mounting base for battery assembly in the first direction, which is beneficial to further reduce the interference between the sealing assembly and the battery when reassembling the battery in the battery operation area, so as to facilitate battery reassembly.

[0025] In some embodiments, along the first direction, a second protrusion is formed on the side of the mounting base opposite to the sealing assembly and corresponding to the position of the second clearance groove.

[0026] In the above technical solution, by forming a second protrusion on the side of the mounting base away from the sealing component along the first direction and at the position corresponding to the second clearance groove, the second clearance groove is a structure that can be formed on the mounting base by a stamping process, which helps to reduce the difficulty of forming the second clearance groove on the mounting base and improves the processing efficiency of the second clearance groove.

[0027] In some embodiments, the sealing assembly includes a first sealing member for sealing a first socket; wherein the first sealing member includes a first body portion and a first plug, the first body portion having a first surface for covering the first socket, the first plug protruding from the first surface and for being inserted into the first socket.

[0028] In the above technical solution, the first sealing member is provided with a first body part and a first plug protruding on the first surface of the first body part. When the first sealing member seals the first socket, the first surface of the first body part can cover the first socket, and the first plug can be inserted into the first socket, so as to achieve double sealing of the first socket by the first body part and the first plug, thereby improving the sealing effect of the first sealing member on the first socket.

[0029] In some embodiments, the electrical device further includes a second connector having a second socket, the second connector being used for fluid connection with a battery, and a first connector being used for electrical connection with a battery; wherein the drive unit is configured to drive the sealing assembly to simultaneously seal the first socket and the second socket or simultaneously open the first socket and the second socket.

[0030] In the above technical solution, the electrical device is also equipped with a second connector. The second connector and the first connector are used for fluid connection and electrical connection with the battery, respectively, so as to realize the electrical connection between the battery and the electrical system of the electrical device and the water circuit of the cooling system. The driving unit can drive the sealing component to simultaneously seal or open the first socket of the first connector and the second socket of the second connector, thereby achieving simultaneous sealing of the first connector and the second connector. On the one hand, the sealing mechanism protects both the first connector and the second connector, reducing the risk of damage to both connectors. On the other hand, it further reduces manual intervention, achieving automatic sealing of the first connector and the second connector of the electrical device without manual intervention, thereby improving the automation level of battery swapping of the electrical device.

[0031] In some embodiments, the sealing assembly includes a second sealing member for sealing the second socket; wherein the second sealing member includes a second body portion and a second plug, the second body portion having a second surface for covering the second socket, the second plug protruding from the second surface and for being inserted into the second socket.

[0032] In the above technical solution, the second sealing member is provided with a second body and a second plug protruding on the second surface of the second body. When the second sealing member seals the second socket, the second surface of the second body can cover the second socket, and the second plug can be inserted into the second socket, so as to achieve double sealing of the second socket by the second body and the second plug, thereby improving the sealing effect of the second sealing member on the second socket.

[0033] In some embodiments, the first socket and the second socket are located on the same side of the mounting base in a first direction; wherein, the blocking mechanism further includes a connecting shaft passing through the mounting base in a first direction, the connecting shaft connecting the drive unit and the blocking assembly, the drive unit being mounted on the side of the mounting base opposite to the first socket and the second socket in the first direction, and the blocking assembly being located on the side of the mounting base opposite to the drive unit.

[0034] In the above technical solution, by setting the first socket of the first connector and the second socket of the second connector to be located on the same side of the mounting base in the first direction, the driving unit can drive the sealing assembly to simultaneously seal the first socket and the second socket, which helps to reduce the difficulty of the sealing assembly simultaneously sealing the first socket and the second socket. Furthermore, by setting the driving unit and the sealing assembly on opposite sides of the mounting base in the first direction, and connecting the driving unit and the sealing assembly via a connecting shaft, the driving unit is installed on the side of the mounting base away from the first socket and the second socket. This helps to save space occupied by the sealing mechanism on the side of the mounting base used for battery installation, and reduces interference between the sealing mechanism and the battery when reassembling the battery in the battery operating area, thus facilitating battery reassembly.

[0035] In some embodiments, the blocking assembly includes a first blocking member, a second blocking member, and a connector, wherein both the first blocking member and the second blocking member are disposed on the side of the connector facing the mounting base; wherein, the driving unit is connected to the connector and is configured to drive the connector to move relative to the mounting base, so as to drive the first blocking member and the second blocking member to block the first socket and the second socket respectively or to open the first socket and the second socket respectively.

[0036] In the above technical solution, the blocking component is provided with a connector and a first blocking component and a second blocking component disposed on the connector. By disposing of both the first blocking component and the second blocking component on the side of the connector facing the mounting base in a first direction, and connecting the connector to the drive unit, the drive unit can drive the connector to move relative to the mounting base, thereby further driving the first blocking component and the second blocking component to block the first socket and the second socket respectively. The blocking mechanism with this structure can reduce the difficulty of the blocking component blocking the first socket and the second socket simultaneously, and can improve the stability and reliability of the blocking component blocking the first socket and the second socket simultaneously.

[0037] In some embodiments, the connector has a first end and a second end opposite to each other in its extending direction, a first sealing member is disposed at the first end, and a second sealing member is disposed at the second end; wherein the connection position between the connector and the drive unit is located between the first end and the second end of the connector.

[0038] In the above technical solution, by setting the first sealing member and the second sealing member respectively on the first end and the second end of the connector opposite to each other in its extension direction, and setting the connection position between the connector and the drive unit to be located between the first end and the second end of the connector, the connection position between the drive unit and the connector is located between the first sealing member and the second sealing member, which is beneficial to improving the stability of the drive unit driving the connector to move relative to the mounting base, and when the first sealing member and the second sealing member respectively block the first socket and the second socket, it is beneficial to improve the force balance of the connector.

[0039] Secondly, embodiments of this application also provide a control method for an electrical device, applicable to the aforementioned electrical device. The control method for the electrical device includes: receiving a control signal; if the control signal is a blocking signal, then performing a first action, the first action being to control a drive unit to drive a blocking component to block a first socket; if the control signal is an opening signal, then performing a second action, the second action being to control a drive unit to drive a blocking component to open the first socket.

[0040] In the above technical solution, the power device can perform a first action and a second action according to different control signals after receiving control signals, so as to control the drive unit to drive the blocking component to block or open the first socket, thereby realizing that the blocking mechanism can automatically block or open the first socket under different usage conditions of the power device. This is beneficial to improve the automation level of the power device, reduce manual intervention, and reduce the failure rate caused by manual operation. In this way, it is beneficial to improve the battery swapping efficiency of the power device and reduce the battery swapping cost of the power device.

[0041] In some embodiments, the first action includes: step S110: controlling the drive unit to drive the sealing assembly to rotate about an axis extending along a first direction to a first position, wherein the sealing assembly at the first position is disposed opposite to the first socket in the first direction; step S120: controlling the drive unit to drive the sealing assembly to move along the first direction toward the mounting base, so that the sealing assembly blocks the first socket.

[0042] In the above technical solution, when the control drive unit drives the blocking component to block the first socket, the control drive unit first drives the blocking component to rotate to a first position that is opposite to the first socket in the first direction, and then controls the drive unit to drive the blocking component to move along the first direction towards the mounting base to block the first socket. The control logic is simple, easy to implement, and helps to improve the reliability of the blocking mechanism in blocking the first socket.

[0043] In some embodiments, before step S110, the first action further includes: step S130: controlling the drive unit to drive the sealing assembly to move away from the mounting base along a first direction, so that the sealing assembly is spaced apart from the first connector in the first direction.

[0044] In the above technical solution, before the control drive unit drives the sealing assembly to rotate around the axis extending along the first direction to the first position, the control drive unit can first drive the sealing assembly to move away from the mounting base along the first direction, so that the sealing assembly can be spaced apart from the first connector in the first direction. This reduces interference or collision between the sealing assembly and the first connector during the process of the drive unit driving the sealing assembly to the first position, thereby helping to alleviate the phenomenon of damage to the first connector or the sealing assembly being unable to rotate smoothly to the first position.

[0045] In some embodiments, the second action includes: step S210: controlling the drive unit to drive the sealing assembly to move away from the mounting base along the first direction, so that the sealing assembly opens the first socket; step S220: controlling the drive unit to drive the sealing assembly to rotate about the axis extending along the first direction to a second position, wherein the sealing assembly in the second position does not overlap with the projection of the first socket in the first direction.

[0046] In the above technical solution, when the control drive unit drives the sealing component to open the first socket, the control drive unit first drives the sealing component to move away from the mounting base along the first direction so that the sealing component is disengaged from the first socket. Then, the control drive unit drives the sealing component to rotate to a second position where the projection of the first socket in the first direction does not overlap. The control logic is simple and easy to implement. While opening the first socket, the sealing component can also avoid the first socket. Therefore, the battery can be reassembled in the battery-operated area without disassembling the sealing mechanism. The degree of automation is high, no manual intervention is required, and the convenience of battery swapping can be improved. This is conducive to further improving the battery swapping efficiency of the power device and further reducing the battery swapping cost of the power device.

[0047] In some embodiments, after step S220, the second action further includes: step S230: controlling the drive unit to drive the sealing assembly to move along the first direction toward the mounting base.

[0048] In the above technical solution, after the control drive unit drives the sealing assembly to rotate around the axis extending along the first direction to the second position, it can also control the drive unit to drive the sealing assembly to move along the first direction towards the mounting base, so that the sealing assembly can share part of the space with the first connector in the first direction. This is beneficial to further reduce the interference between the sealing assembly and the battery when reassembling the battery in the area where the battery is running, so as to facilitate the reassembly of the battery.

Currently, new energy vehicles typically use dual-pack or multi-pack systems, meaning they are equipped with multiple batteries. To meet the fast-swap requirements of these batteries, quick-swap connectors are commonly used to connect each battery pack to the vehicle's electrical system, as well as to connect the battery packs to the vehicle's electrical system via water circuits. The quick-swap connector's connector plug and connector are located on the battery and the vehicle body, respectively. The connector plug mates with the connector to establish the quick-swap connection.

[0076] In new energy vehicles, to achieve the electrical connection between the battery and the vehicle's electrical system, and the water connection between the battery and the vehicle's cooling system, quick-connect electrical connectors and quick-connect water connectors are installed between the battery and the vehicle. The quick-connect electrical connectors enable the electrical connection between the battery and the vehicle's electrical system, and the quick-connect water connectors enable the water connection between the battery and the vehicle's cooling system. To facilitate battery assembly and quick replacement, the electrical connector plugs and water connector plugs are typically mounted on the battery and installed on the vehicle's mounting bracket. The plug-in mating between the electrical connector plugs and connectors enables the electrical connection between each battery and the vehicle's electrical system, and the plug-in mating between the water connector plugs and connectors enables the water connection between each battery and the vehicle's cooling system. However, when new energy vehicles with dual or multiple battery pack systems require battery reduction, meaning that a new energy vehicle equipped with multiple batteries may only need to install a small number of batteries under different usage conditions, the electrical and water connectors in the non-battery locations on the vehicle are exposed and lack sealing function. This makes it very easy for impurities or particles to enter the electrical and water connectors during vehicle use, causing damage. In related technologies, to alleviate the phenomenon of damage to electrical and water connectors during battery reduction, seals are usually installed manually on the vehicle's electrical and water connectors or dummy battery packs are installed to alleviate the problem of exposed electrical and water connectors in non-battery locations. However, this method results in a low degree of automation in vehicle battery swapping, which is not conducive to improving the battery swapping efficiency of the electrical device. Moreover, manual operation is very prone to malfunctions or poor sealing, and the problem of easily damaged electrical and water connectors still exists. Furthermore, installing dummy battery packs will occupy storage space at the battery swapping station, which is not conducive to reducing the operating cost of the electrical device.

[0077] Based on the above considerations, and to address the issue of high operating costs in the later stages of use of electrical devices, this application provides an electrical device comprising a mounting base, a first connector, and a sealing mechanism. The first connector is mounted on the mounting base and has a first socket. The first connector is used for electrical or fluid connection with a battery. The sealing mechanism includes a drive unit and a sealing assembly. The drive unit is mounted on the mounting base, and the sealing assembly is connected to the drive unit. The drive unit is configured to drive the sealing assembly to move relative to the mounting base to seal or open the first socket.

[0078] In this type of electrical device, a first connector is provided for electrical or fluid connection with a battery, facilitating electrical connection between the battery and the device's electrical system or water circuit connection with its cooling system. A sealing mechanism, comprising a drive unit and a sealing assembly, is provided on the device. The drive unit is mounted on a mounting base of the device, enabling it to move the sealing assembly relative to the mounting base. This allows the sealing assembly to seal or open the first socket of the first connector, thereby sealing the first connector. This type of electrical device, through its sealing mechanism, enables electrical... During battery swapping, the device automatically seals the exposed first connector on the power-consuming device. This reduces the likelihood of the first connector being exposed, mitigating the risk of impurities or particles from the external environment entering it and thus lowering the subsequent operating costs of the power-consuming device. Furthermore, the automatic sealing of the first connector without manual intervention enhances the automation of battery swapping, reduces the failure rate caused by manual operation, and ultimately improves the battery swapping efficiency and reduces the cost of battery swapping.

[0079] This application provides an electrical device that uses a battery as a power source. The electrical device can be, but is not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0080] Please refer to Figure 1, which is a schematic diagram of the structure of an electrical device 1000 provided in some embodiments of this application. For ease of explanation, the following embodiments use a vehicle as an example of an electrical device 1000 according to one embodiment of this application. The vehicle can be a gasoline vehicle, a natural gas vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery 100 is installed inside the vehicle. The battery 100 can be located at the bottom, front, or rear of the vehicle. The battery 100 can be used to power the electrical device 1000; for example, the battery 100 can serve as the operating power or general power source for the electrical device 1000. The electrical device 100 may also include a controller 200 and a motor 300. The controller 200 controls the battery 100 to supply power to the motor 300, for example, to meet the power requirements of the electrical device 1000 during startup, navigation, and driving.

[0081] In some embodiments of this application, the battery 100 can not only serve as the operating power or power source for the electrical device 1000, but also as the driving power source for the electrical device 1000, replacing or partially replacing fuel oil or natural gas to provide driving power for the electrical device 1000.

[0082] Referring to Figure 2, which is an exploded view of the structure of a battery 100 provided in some embodiments of this application, the battery 100 may include a housing 110 and battery cells 120, with the battery cells 120 being housed within the housing 110. The housing 110 provides assembly space for the battery cells 120, and the housing 110 may employ various structures. In some embodiments, the housing 110 may include a first housing body 111 and a second housing body 112, which overlap each other, and together define an assembly space for accommodating the battery cells 120. The second box body 112 can be a hollow structure with one end open, and the first box body 111 can be a plate-like structure. The first box body 111 covers the open side of the second box body 112 so that the first box body 111 and the second box body 112 together define the assembly space; the first box body 111 and the second box body 112 can also both be hollow structures with one side open, and the open side of the first box body 111 covers the open side of the second box body 112.

[0083] Optionally, the box 110 formed by the first box body 111 and the second box body 112 can be of various shapes, such as a cylinder, a cuboid, or a cube.

[0084] In battery 100, there may be one or more battery cells 120 disposed within housing 110. When there are multiple battery cells 120 disposed within housing 110, they may be connected in series, in parallel, or in a mixed configuration. A mixed configuration means that multiple battery cells 120 are connected in both series and parallel configurations. Multiple battery cells 120 may be directly connected in series, in parallel, or in a mixed configuration, and then the entire assembly of the multiple battery cells 120 is housed within housing 110. Alternatively, battery 100 may be composed of multiple battery cells 120 first connected in series, in parallel, or in a mixed configuration to form a battery module, and then multiple battery modules are connected in series, in parallel, or in a mixed configuration to form a whole, which is then housed within housing 110. In some embodiments, battery 100 may also include other structures. For example, battery 100 may also include a busbar component for connecting multiple battery cells 120 to achieve electrical connection between the multiple battery cells 120.

[0085] Each battery cell 120 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. The battery cell 120 can be in the form of a cuboid, cylinder, prism, or other shapes.

[0086] In some embodiments, referring to FIG1 and further referring to FIG3, FIG3 is a partial structural schematic diagram of an electrical device 1000 provided in some embodiments of the present application. The electrical device 1000 has a mounting bracket 400, on which the controller 200 and the motor 300 are mounted. A plurality of mounting cavities 410 are formed on the mounting bracket 400, and each mounting cavity 410 corresponds to a battery 100. Each mounting cavity 410 is used to accommodate and assemble a battery 100, so as to assemble the battery 100 onto the electrical device 1000.

[0087] According to some embodiments of this application, referring to Figure 3, and further referring to Figures 4, 5, 6, 7, and 8, Figure 4 is a schematic diagram of the assembly of the blocking mechanism 800 and the mounting base 500 provided in some embodiments of this application; Figure 5 is a schematic structural diagram of the blocking mechanism 800 provided in some embodiments of this application; Figure 6 is a bottom view of the blocking mechanism 800 assembled on the mounting base 500 (when the blocking mechanism 800 blocks the first socket 610 and the second socket 710) provided in some embodiments of this application; Figure 7 is a front view of the blocking mechanism 800 assembled on the mounting base 500 (when the blocking mechanism 800 blocks the first socket 610 and the second socket 710) provided in some embodiments of this application; and Figure 8 is a front view of the blocking mechanism 800 assembled on the mounting base 500 (when the blocking assembly 820 is in the first position) provided in some embodiments of this application. This application provides an electrical device 1000, which includes a mounting base 500, a first connector 600, and a blocking mechanism 800. A first connector 600 is mounted on a mounting base 500. The first connector 600 has a first socket 610 and is used for electrical or fluid connection with the battery 100. A sealing mechanism 800 includes a drive unit 810 and a sealing assembly 820. The drive unit 810 is mounted on the mounting base 500, and the sealing assembly 820 is connected to the drive unit 810. The drive unit 810 is configured to drive the sealing assembly 820 to move relative to the mounting base 500 to seal or open the first socket 610.

[0088] The mounting base 500 serves to assemble and fix the first connector 600 and the sealing mechanism 800. The mounting base 500 is fastened to the mounting bracket 400. The connection structure between the mounting base 500 and the mounting bracket 400 can be various, such as welding connection, bolt connection or snap connection.

[0089] For example, in Figure 4, the mounting base 500 is a plate-shaped structure, and the mounting base 500 is bent at both of its opposite ends toward the same side in the first direction X to form two bending areas 510. Both bending areas 510 are used to install and fasten to the mounting bracket 400 to reduce the assembly difficulty between the mounting base 500 and the mounting bracket 400.

[0090] It should be noted that the first connector 600 and the sealing mechanism 800 are both mounted on the mounting base 500, and the first connector 600 and the sealing mechanism 800 are respectively set one-to-one with the battery 100. That is to say, each mounting cavity 410 of each mounting bracket 400 is provided with a mounting base 500, and each mounting base 500 is equipped with a first connector 600. Similarly, each mounting base 500 is also provided with a sealing mechanism 800.

[0091] For example, in Figure 4, the first connector 600 is bolted to the mounting base 500, and all the first connectors 600 are inserted into the mounting base 500 along the first direction X, such that the first socket 610 of the first connector 600 is located on one side of the mounting base 500 in the first direction X. Of course, in other embodiments, the first connector 600 can also be assembled onto the mounting base 500 by welding or snap-fitting.

[0092] The first connector 600 is used for electrical or fluid connection with the battery 100. That is, the first connector 600 can be an electrical connector for electrical connection with the battery 100 or a water connector for water connection with the battery 100.

[0093] For example, the first connector 600 is electrically connected to the power system of the power-consuming device 1000, that is, the first connector 600 is an electrical connector for electrically connecting to the battery 100. The first connector 600 is used to mate with a first plug, which is disposed on the housing 110 of the battery 100 and electrically connected to the battery cell 120 inside the housing 110, so that after the first connector 600 mates with the first plug, an electrical connection can be realized between the battery 100 and the power system of the power-consuming device 1000.

[0094] The first connector 600 has a first socket 610 for inserting a first plug, that is, the first connector 600 has a first socket 610 formed therein, and the first plug on the battery 100 can be inserted into the first socket 610 to achieve the insertion and mating of the first connector 600 and the first plug. For example, the first socket 610 of the first connector 600 is used for inserting the first plug on the battery 100 along a first direction X.

[0095] In some embodiments, referring to Figures 3 and 4, the electrical device 1000 may also be provided with a second connector 700, which is used for fluid connection with the battery 100. That is, the second connector 700 is a water connector for water connection with the battery 100, and the second connector 700 is water connected to the cooling system of the electrical device 1000. Referring to Figures 7 and 8, the second connector 700 has a second socket 710 for inserting a second plug. The drive unit 810 of the sealing mechanism 800 is configured to drive the sealing assembly 820 to move relative to the mounting base 500, so as to simultaneously seal the first socket 610 and the second socket 710 or simultaneously open the first socket 610 and the second socket 710.

[0096] The second connector 700 is used to engage with the second plug. The second plug is disposed on the housing 110 of the battery 100 and is connected to the thermal management system inside the housing 110, so that after the second connector 700 engages with the second plug, a water connection can be realized between the thermal management system of the battery 100 and the cooling system of the electrical device 1000.

[0097] The second connector 700 has a second socket 710 for inserting a second plug. Specifically, the second connector 700 has a second socket 710 formed therein, and the second plug on the battery 100 can be inserted into the second socket 710 to achieve a mating connection between the second connector 700 and the second plug. For example, the second socket 710 of the second connector 700 is used for inserting the second plug on the battery 100 along a first direction X.

[0098] Optionally, both the second connector 700 and the first connector 600 are mounted on the mounting base 500, and the second connector 700 is also configured in a one-to-one correspondence with the battery 100. That is, each mounting cavity 410 of each mounting bracket 400 is provided with a mounting base 500, and each mounting base 500 is equipped with a second connector 700.

[0099] For example, in Figure 4, the second connector 700 is bolted to the mounting base 500, and the second connector 700 also passes through the mounting base 500 along the first direction X, such that the first socket 610 of the first connector 600 and the second socket 710 of the second connector 700 are both located on the same side of the mounting base 500 in the first direction X. Of course, in other embodiments, the second connector 700 can also be assembled onto the mounting base 500 by welding or snap-fitting.

[0100] Referring to Figures 4, 7, and 8, along the first direction X, the first connector 600 and the second connector 700 are both inserted into the mounting base 500 and protrude from the side of the mounting base 500 facing the battery 100, such that the first socket 610 of the first connector 600 and the second socket 710 of the second connector 700 are both positioned facing the battery 100 along the first direction X, so that the first plug and the second plug on the battery 100 can be inserted into the first socket 610 and the second socket 710 respectively along the first direction X.

[0101] A sealing mechanism 800 is disposed on the mounting base 500. The sealing mechanism 800 functions to seal the first socket 610 of the first connector 600, thereby achieving a seal on the first socket 610 of the first connector 600. Of course, in embodiments where the electrical device 1000 also includes a second connector 700, the sealing mechanism 800 can also seal the second socket 710 of the second connector 700, thereby simultaneously achieving a seal on the first socket 610 of the first connector 600 and a seal on the second socket 710 of the second connector 700.

[0102] As shown in Figure 3, the electrical device 1000 is equipped with multiple batteries 100. When it is necessary to reduce the number of batteries 100, that is, to remove some batteries 100 from the mounting bracket 400, the first connector 600 and the second connector 700 mounted on the mounting seat 500 at the position of the removed battery 100 in the mounting cavity 410 are both suspended and exposed. Thus, the sealing mechanism 800 can seal and block the first connector 600 and the second connector 700 to reduce the risk of use of the electrical device 1000 during use.

[0103] The blocking mechanism 800 includes a drive unit 810 and a blocking component 820. The blocking component 820 is connected to the drive unit 810. The drive unit 810 is configured to drive the blocking component 820 to move relative to the mounting base 500 to block the first socket 610. That is, the blocking component 820 can move relative to the mounting base 500, so that the blocking component 820 can move towards the first socket 610 under the drive of the drive unit 810, so that the blocking component 820 blocks the first socket 610 of the first connector 600.

[0104] Alternatively, the structure by which the drive unit 810 is mounted on the mounting base 500 can be varied, such as welded connection, bolted connection, or snap-fit ​​connection.

[0105] Referring to Figures 5, 7, and 8, the sealing assembly 820 may include a connector 823 and a first sealing member 821. Along the first direction X, the drive unit 810 is mounted on the side of the mounting base 500 opposite to the first socket 610. The connector 823 is located on the side of the mounting base 500 opposite to the drive unit 810 and is connected to the drive unit 810. The first sealing member 821 is disposed on the side of the connector 823 facing the mounting base 500. The drive unit 810 is configured to drive the connector 823 to move relative to the mounting base 500, so as to drive the first sealing member 821 to seal the first socket 610.

[0106] Optionally, the first sealing element 821 can be made of various materials, such as rubber, silicone, or plastic.

[0107] Of course, in an embodiment where the electrical device 1000 is also provided with a second connector 700, in Figures 5, 7 and 8, the first socket 610 and the second socket 710 are located on the same side of the mounting base 500 in the first direction X. The sealing assembly 820 may also include a second sealing member 822. The second sealing member 822 and the first sealing member 821 are both disposed on the side of the connector 823 facing the mounting base 500. The drive unit 810 is configured to drive the connector 823 to move relative to the mounting base 500, so as to drive the first sealing member 821 and the second sealing member 822 to seal the first socket 610 and the second socket 710 respectively.

[0108] Optionally, the second sealing element 822 can be made of various materials, such as rubber, silicone, or plastic.

[0109] In this embodiment, the electrical device 1000 is provided with a first connector 600 for electrical or fluid connection with the battery 100, so as to realize the electrical connection between the battery 100 and the electrical system of the electrical device 1000 or the water circuit connection of the cooling system. By providing a sealing mechanism 800 on the electrical device 1000, the sealing mechanism 800 includes a drive unit 810 and a sealing component 820. The drive unit 810 is mounted on the mounting base 500 of the electrical device 1000, so that the drive unit 810 can drive the sealing component 820 to move relative to the mounting base 500, so that the sealing component 820 can block or open the first socket 610 of the first connector 600, thereby sealing the first connector 600. The electrical device 1000 with this structure can achieve sealing by blocking. The mechanism 800 can automatically seal the exposed first connector 600 on the power device 1000 during the operation of the power device 1000 and battery 100. On the one hand, it can reduce the phenomenon of the first connector 600 being exposed, thereby mitigating the possibility of impurities or particles from the external environment entering the first connector 600, and thus effectively reducing the risk of damage to the first connector 600, thereby reducing the subsequent use cost of the power device 1000. On the other hand, it can achieve automatic sealing of the first connector 600 of the power device 1000 without human intervention, thereby improving the automation level of battery swapping of the power device 1000 and reducing the failure rate caused by manual operation. This is conducive to improving the battery swapping efficiency of the power device 1000 and reducing the battery swapping cost of the power device 1000.

[0110] According to some embodiments of this application, referring to Figures 5, 7 and 8, the drive unit 810 may include a first drive member 811, which is mounted on the mounting base 500. The first drive member 811 is connected to the blocking assembly 820 and is configured to drive the blocking assembly 820 to move along a first direction X to block or open the first socket 610.

[0111] The drive unit 810 may include a first drive member 811, which is configured to drive the blocking assembly 820 to move along the first direction X. That is, the drive unit 810 is provided with a first drive member 811 that can drive the blocking assembly 820 to move relative to the mounting base 500 in the first direction X, so that the blocking assembly 820 can move closer to or further away from the first socket 610 in the first direction X, thereby enabling the blocking assembly 820 to block or open the first socket 610.

[0112] For example, the structure of the first drive element 811 can be various, such as a cylinder, a hydraulic cylinder, or a linear motor.

[0113] The first driving component 811 is mounted on the mounting base 500 and connected to the sealing assembly 820. That is, the first driving component 811 is assembled on the mounting base 500, and its output end is connected to the sealing assembly 820, so that the first driving component 811 drives the sealing assembly 820 to move relative to the mounting base 500 along the first direction X. It should be noted that the output end of the first driving component 811 and the sealing assembly 820 can be directly connected or indirectly connected.

[0114] Similarly, the structure by which the first drive component 811 is mounted on the mounting base 500 can be varied. For example, the first drive component 811 can be mounted on the mounting base 500 by means of bolting, snap-fitting, bonding, or welding.

[0115] In this embodiment, the driving unit 810 is provided with a first driving member 811, and the first driving member 811 can drive the blocking component 820 to move relative to the mounting base 500 along the first direction X, so as to block or open the first socket 610 of the first connector 600 by moving the blocking component 820 along the first direction X. The blocking mechanism 800 with this structure is convenient for the blocking component 820 to block the first socket 610 of the first connector 600, which helps to reduce the difficulty of the blocking component 820 to block the first socket 610 of the first connector 600. The structure is simple and easy to implement. On the other hand, it can effectively improve the stability and reliability of the blocking component 820 in blocking the first socket 610 of the first connector 600.

[0116] According to some embodiments of this application, referring to Figures 5, 6, 7, and 8, and further referring to Figure 9, Figure 9 is a bottom view of the sealing mechanism 800 provided in some embodiments of this application mounted on the mounting base 500 (when the sealing assembly 820 is in the second position). The drive unit 810 may further include a second drive member 812, which is connected to the output end of the first drive member 811. The first drive member 811 is configured to drive the second drive member 812 to move along a first direction X. The sealing assembly 820 is connected to the output end of the second drive member 812, and the second drive member 812 is configured to drive the sealing assembly 820 to rotate between a first position and a second position about an axis extending along the first direction X. When the sealing assembly 820 is in the first position, the first drive member 811 can drive the sealing assembly 820 to move along the first direction X and seal the first socket 610; when the sealing assembly 820 is in the second position, the projection of the first socket 610 in the first direction X does not overlap with the sealing assembly 820.

[0117] The drive unit 810 may further include a second drive member 812, which is configured to drive the sealing assembly 820 to rotate between a first position and a second position about an axis extending along the first direction X. In other words, the drive unit 810 is further provided with a second drive member 812 capable of driving the sealing assembly 820 to rotate relative to the mounting base 500 about an axis extending along the first direction X, so that the sealing assembly 820 can switch between the first position and the second position relative to the mounting base 500.

[0118] For example, the structure of the second drive element 812 can be various, such as an electric motor, a rotary cylinder, or a hydraulic motor 300.

[0119] The second driving member 812 is connected to the output end of the first driving member 811. The first driving member 811 is configured to drive the second driving member 812 to move along the first direction X. The sealing assembly 820 is connected to the output end of the second driving member 812. That is, the first driving member 811 of the driving unit 810 is mounted on the mounting base 500, the second driving member 812 is connected to the output end of the first driving member 811, and the sealing assembly 820 is connected to the output end of the second driving member 812. This structure allows the second driving member 812 to drive the sealing member to rotate relative to the mounting base 500 about an axis extending along the first direction X, while the first driving member 811 can drive the second driving member 812 to move along the first direction X, thereby causing the sealing member to move relative to the mounting base 500 in the first direction X. It should be noted that the output end of the second driving member 812 and the sealing assembly 820 can be directly connected or indirectly connected.

[0120] For example, in FIG4, the drive unit 810 may further include a movable seat 813, which is movably disposed on the mounting base 500 along the first direction X. The movable seat 813 is connected to the output end of the first drive member 811. The first drive member 811 is configured to drive the movable seat 813 to move relative to the mounting base 500 along the first direction X. The second drive member 812 is mounted on the movable seat 813 so that the first drive member 811 can drive the second drive member 812 to move relative to the mounting base 500 along the first direction X. The drive unit 810 with this structure facilitates the assembly between the first drive member 811 and the second drive member 812, which helps to reduce the assembly difficulty.

[0121] When the blocking component 820 is in the first position, the first driving member 811 can drive the blocking component 820 to move along the first direction X and block the first socket 610. That is, as shown in Figure 8, when the blocking component 820 is in the first position, the blocking component 820 and the first socket 610 are arranged opposite each other in the first direction X, so that the blocking component 820 can block or open the first socket 610 by moving closer to or away from the first socket 610 along the first direction X under the drive of the first driving member 811. It should be noted that in the embodiment where the electrical device 1000 includes a second connector 700, the second connector 700 has a second socket 710, and the blocking component 820 is also configured to block or open the second connector 700, when the blocking component 820 is in the first position, the blocking component 820 and the second socket 710 are also arranged opposite each other in the first direction X, so that the blocking component 820 can block or open the first socket 610 and the second socket 710 by moving closer to or away from the first socket 610 and the second socket 710 in the first direction X under the drive of the first driving member 811.

[0122] When the blocking component 820 is in the second position, the projection of the first socket 610 in the first direction X does not overlap with the blocking component 820. That is, as shown in Figure 9, when the blocking component 820 is in the second position, the blocking component 820 and the first socket 610 are staggered in the first direction X, so that the blocking component 820 does not cover or block the first socket 610 in the first direction X, thereby enabling the blocking component 820 to avoid the first socket 610. It should be noted that in the embodiment where the electrical device 1000 includes a second connector 700, the second connector 700 has a second socket 710, and the blocking component 820 is also configured to block or open the second connector 700, when the blocking component 820 is in the second position, the blocking component 820 and the second socket 710 are also staggered in the first direction X, so that the blocking component 820 neither covers or blocks the first socket 610 nor the second socket 710 in the first direction X, thereby enabling the blocking component 820 to avoid the first socket 610 and the second socket 710.

[0123] In this embodiment, the driving unit 810 is further provided with a second driving member 812, and the second driving member 812 can drive the sealing assembly 820 to rotate relative to the mounting base 500 about an axis extending along the first direction X, so that the sealing assembly 820 can switch between a first position and a second position. When the sealing assembly 820 is in the first position, it only needs to move along the first direction X under the drive of the first driving member 811 to seal or open the first socket 610 of the first connector 600, and when the sealing assembly 820 is in the second position... In the second position, the projection of the first socket 610 of the first connector 600 in the first direction X is not overlapped, so that the sealing component 820 can avoid the first socket 610 of the first connector 600. Thus, the battery 100 can be reassembled in the area where the battery 100 is running without disassembling the sealing mechanism 800. The operation is simple and can improve the convenience of battery replacement, which is conducive to further improving the battery replacement efficiency of the power device 1000 and further reducing the battery replacement cost of the power device 1000.

[0124] According to some embodiments of this application, referring to Figures 5, 7, and 8, along the first direction X, the second driving member 812 and the blocking assembly 820 are respectively located on both sides of the mounting base 500. The blocking mechanism 800 may further include an elastic member 830, which is compressed between the second driving member 812 and the mounting base 500 along the first direction X, and both ends of the elastic member 830 abut against the second driving member 812 and the mounting base 500 respectively.

[0125] Along the first direction X, the second driving member 812 and the sealing assembly 820 are respectively located on both sides of the mounting base 500. That is, in the first direction X, the second driving member 812 and the sealing assembly 820 of the driving unit 810 are respectively disposed on both sides of the mounting base 500, so that at least a portion of the mounting base 500 is located between the second driving member 812 and the sealing assembly 820.

[0126] For example, the first drive member 811 of the drive unit 810 is mounted on the side of the mounting base 500 facing away from the blocking assembly 820 in the first direction X, and the movable seat 813 is also located on the side of the mounting base 500 facing away from the blocking assembly 820 in the first direction X.

[0127] Optionally, in Figures 5 and 7, the blocking mechanism 800 is further provided with a connecting shaft 840, which extends along the first direction X. The mounting base 500 has mounting holes that extend through both sides of the mounting base 500 along the first direction X. The connecting shaft 840 passes through the mounting holes along the first direction X, and its two ends along the first direction X are respectively connected to the output ends of the blocking assembly 820 and the second driving member 812, thereby reducing the assembly difficulty between the blocking assembly 820 and the second driving member 812. Of course, in other embodiments, the blocking mechanism 800 may not have the connecting shaft 840. Instead, the output end of the second driving member 812 can be extended along the first direction X and passed through the mounting holes, allowing the blocking assembly 820 to be directly connected to the output end of the second driving member 812.

[0128] Along the first direction X, the elastic member 830 is compressed between the second drive member 812 and the mounting base 500, and both ends of the elastic member 830 abut against the second drive member 812 and the mounting base 500 respectively. That is, the elastic member 830 is assembled between the second drive member 812 and the mounting base 500 in a compressed state in the first direction X, so that the elastic member 830 can provide the second drive member 812 with an elastic force that moves away from the mounting base 500 in the first direction X. When the first drive member 811 fails, the second drive member 812 has a tendency to move away from the mounting base 500 in the first direction X. At the same time, the sealing assembly 820 has a tendency to move away from the mounting base 500 in the first direction X, so as to keep the sealing assembly 820 in the position of sealing the first socket 610 and the second socket 710.

[0129] For example, the structure of the elastic element 830 can be various. The elastic element 830 can be a spring, elastic rubber or sheet, etc., disposed between the second drive member 812 and the mounting base 500. The sheet can be a "V" shaped sheet, an "N" shaped sheet or an "M" shaped sheet, etc.

[0130] In this embodiment, the second driving member 812 and the sealing assembly 820 are respectively disposed on both sides of the mounting base 500 along the first direction X. An elastic member 830 is also disposed between the second driving member 812 and the mounting base 500, in a compressed state. This allows the second driving member 812 to tend to move away from the mounting base 500 along the first direction X under the elastic force of the elastic member 830, thereby enabling the elastic member 830 to push the sealing assembly 820... By maintaining the first socket 610 in the blocked position, the blocking mechanism 800 with this structure can continue to keep the blocking component 820 in the blocked first socket 610 state through the elastic member 830 when the first driving member 811 fails. This can alleviate the phenomenon that the blocking component 820 may accidentally disengage from the first socket 610 when the first driving member 811 fails. In this way, the blocking mechanism 800 can achieve a double insurance function, which is conducive to further improving the stability and reliability of the blocking mechanism 800 in blocking the first socket 610 of the first connector 600.

[0131] In some embodiments, as shown in Figures 5, 7 and 8, the blocking mechanism 800 may further include a connecting shaft 840 that passes through the mounting base 500 along a first direction X. The connecting shaft 840 is connected to the output end of the blocking assembly 820 and the second drive member 812, and an elastic member 830 is sleeved on the outside of the connecting shaft 840.

[0132] For example, the elastic element 830 is a spring sleeved on the connecting shaft 840, that is, the connecting shaft 840 passes through the elastic element 830, and the two ends of the elastic element 830 in the first direction X respectively abut against the second driving member 812 and the mounting base 500. Of course, the elastic element 830 can also be an elastic rubber sleeved on the connecting shaft 840, the elastic rubber having through holes extending through both ends along the first direction X, and the connecting shaft 840 passing through the through holes.

[0133] In this embodiment, the sealing mechanism 800 is further provided with a connecting shaft 840 passing through the mounting base 500 along the first direction X. The connecting shaft 840 is connected to the sealing assembly 820 and the second driving member 812 located on both sides of the mounting base 500, so that the driving unit 810 can drive the sealing assembly 820 to move relative to the mounting base 500. By sleeved on the outside of the connecting shaft 840, and with both ends of the elastic member 830 abutting against the second driving member 812 and the mounting base 500 in the first direction X, the installation of the elastic member 830 can be reduced. The connection between the second drive member 812 and the mounting base 500 is simplified, and the stability of the elastic member 830 assembled between the second drive member 812 and the mounting base 500 is improved. On the other hand, the connecting shaft 840 can guide the elastic member 830 so that the elastic member 830 can deform stably along the first direction X. This allows the elastic member 830 to provide a relatively stable elastic force to the second drive member 812 to move away from the mounting base 500 in the first direction X, so as to keep the sealing assembly 820 in the position of sealing the first socket 610.

[0134] According to some embodiments of this application, referring to Figures 5, 6, and 9, and further referring to Figure 10, Figure 10 is a front view of the sealing mechanism 800 provided in some embodiments of this application assembled on the mounting base 500 (when the first sealing member 821 and the second sealing member 822 are respectively accommodated in the first clearance groove 520 and the second clearance groove 530). The sealing assembly 820 may include the first sealing member 821, which is used to seal the first socket 610. The mounting base 500 is provided with a first clearance groove 520 on the side facing the sealing assembly 820 in the first direction X. When the sealing assembly 820 is in the second position, the first sealing member 821 is disposed opposite to the first clearance groove 520 along the first direction X, and the first clearance groove 520 is used to accommodate at least a portion of the first sealing member 821.

[0135] The blocking assembly 820 may include a first blocking member 821, which is used to block the first socket 610. That is, the blocking assembly 820 has a first blocking member 821 for blocking the first socket 610 of the first connector 600, so that when the driving unit 810 drives the blocking assembly 820 to move along the first direction X toward the first socket 610, the first blocking member 821 can block the first socket 610.

[0136] When the sealing assembly 820 is in the second position, the first sealing member 821 is disposed opposite to the first clearance groove 520 along the first direction X. The first clearance groove 520 is used to accommodate at least a portion of the first sealing member 821. That is, when the sealing assembly 820 is in the second position, the projection of the first sealing member 821 of the sealing assembly 820 in the first direction X is located in the first clearance groove 520, so that when the driving unit 810 drives the sealing assembly 820 to move along the first direction X toward the mounting base 500, the first sealing member 821 can be inserted into the first clearance groove 520, so that the first clearance groove 520 can accommodate at least a portion of the first sealing member 821.

[0137] For example, in this embodiment, the first sealing member 821 is made of rubber. By making the first sealing member 821 of rubber, the first sealing member 821 has a certain elastic deformation capability. On the one hand, this reduces the rigid contact between the first sealing member 821 and the first connector 600, which helps to reduce the risk of the first sealing member 821 damaging the first connector 600. On the other hand, it enables the first sealing member 821 to be pressed tightly onto the first socket 610 of the first connector 600, which helps to further improve the effect of the first sealing member 821 in sealing the first socket 610 of the first connector 600.

[0138] In this embodiment, the sealing assembly 820 is provided with a first sealing member 821 for sealing the first socket 610. By providing a first clearance groove 520 on the side of the mounting base 500 facing the sealing assembly 820 along the first direction X, and when the sealing assembly 820 is in the second position, the first sealing member 821 of the sealing assembly 820 can be disposed opposite to the first clearance groove 520 in the first direction X, so that the first driving member 811 of the driving unit 810 can also drive the sealing assembly 820 in the second position to move along the first direction X toward the mounting base 500, so that at least a part of the first sealing member 821 can be accommodated in the first clearance groove 520. This reduces the space occupied by the sealing assembly 820 on the side of the mounting base 500 for assembling the battery 100 in the first direction X, which is beneficial to further reduce the interference between the sealing assembly 820 and the battery 100 when reassembling the battery 100 in the area where the battery 100 is running, so as to facilitate the reassembly of the battery 100.

[0139] In some embodiments, as shown in Figures 4 and 6, a first protrusion 540 is formed on the side of the mounting base 500 opposite to the sealing assembly 820 and corresponding to the position of the first clearance groove 520 along the first direction X.

[0140] For example, the first clearance groove 520 provided on the side of the mounting base 500 facing the sealing assembly 820 is formed by a stamping process, so that the first clearance groove 520 is formed on the side of the mounting base 500 facing the sealing assembly 820, and a first protrusion 540 is formed on the side of the mounting base 500 away from the sealing assembly 820 at a position corresponding to the first clearance groove 520. Of course, the processing method of the first clearance groove 520 provided on the side of the mounting base 500 facing the sealing assembly 820 is not limited to this. In other embodiments, the first clearance groove 520 provided on the side of the mounting base 500 facing the sealing assembly 820 can also be formed by a processing process such as casting or milling.

[0141] In this embodiment, by forming a first protrusion 540 on the side of the mounting base 500 away from the sealing component 820 along the first direction X and at the position corresponding to the first clearance groove 520, the first clearance groove 520 is a structure that can be formed on the mounting base 500 by a stamping process, which helps to reduce the difficulty of forming the first clearance groove 520 on the mounting base 500 and helps to improve the processing efficiency of the first clearance groove 520.

[0142] According to some embodiments of this application, referring to Figures 5, 6, 7, 8, and 9, the electrical device 1000 may further include a second connector 700 having a second socket 710. The second connector 700 is used for fluid connection with the battery 100, and the first connector 600 is used for electrical connection with the battery 100. The drive unit 810 is configured to drive the sealing assembly 820 to simultaneously seal the first socket 610 and the second socket 710 or simultaneously open the first socket 610 and the second socket 710. When the sealing assembly 820 is in a first position, the first drive member 811 can drive the sealing assembly 820 to move along a first direction X and seal the first socket 610 and the second socket 710; when the sealing assembly 820 is in a second position, the projections of the first socket 610 and the second socket 710 in the first direction X do not overlap with the sealing assembly 820.

[0143] The drive unit 810 is configured to drive the blocking assembly 820 to simultaneously block the first socket 610 and the second socket 710 or simultaneously open the first socket 610 and the second socket 710. That is, when the drive unit 810 drives the blocking assembly 820 to move along the first direction X toward the mounting base 500, it can simultaneously block the first socket 610 of the first connector 600 and the second socket 710 of the second connector 700. And when the drive unit 810 drives the blocking assembly 820 to move along the first direction X away from the mounting base 500, it can simultaneously open the first socket 610 of the first connector 600 and the second socket 710 of the second connector 700.

[0144] When the blocking component 820 is in the first position, the first driving member 811 can drive the blocking component 820 to move along the first direction X and block the first socket 610 and the second socket 710. That is, as shown in Figure 8, when the blocking component 820 is in the first position, the first socket 610 and the second socket 710 are both arranged opposite to the blocking component 820 in the first direction X, so that the blocking component 820 can block or open the first socket 610 and the second socket 710 by moving closer to or away from the first socket 610 along the first direction X under the drive of the first driving member 811.

[0145] When the blocking component 820 is in the second position, the projections of the first socket 610 and the second socket 710 in the first direction X do not overlap with the blocking component 820. That is, as shown in Figure 9, when the blocking component 820 is in the second position, the first socket 610 and the second socket 710 are staggered from the blocking component 820 in the first direction X, so that the blocking component 820 does not cover or block the first socket 610 and the second socket 710 in the first direction X, thereby enabling the blocking component 820 to avoid the first socket 610 and the second socket 710.

[0146] In this embodiment, the power device 1000 is also provided with a second connector 700. The second connector 700 and the first connector 600 are used for fluid connection and electrical connection with the battery 100, respectively, so as to realize the electrical connection between the battery 100 and the power system of the power device 1000 and the water circuit connection of the cooling system. The driving unit 810 can drive the sealing component 820 to simultaneously seal or open the first socket 610 of the first connector 600 and the second socket 710 of the second connector 700, thereby achieving simultaneous sealing of the first connector 600 and the second connector 700. On the one hand, the sealing mechanism 800 protects both the first connector 600 and the second connector 700, reducing the risk of damage to both the first connector 600 and the second connector 700. On the other hand, it can further reduce manual intervention, and the automatic sealing of the first connector 600 and the second connector 700 of the power device 1000 can be achieved without manual intervention, thereby improving the automation level of battery swapping of the power device 1000. Furthermore, the second driving member 812 can drive the sealing assembly 820 to rotate relative to the mounting base 500 around an axis extending along the first direction X, so that the sealing assembly 820 can switch between a first position and a second position. When the sealing assembly 820 is in the first position, it only needs to move along the first direction X under the drive of the first driving member 811 to seal or open the first socket 610 and the second socket 710. When the sealing assembly 820 is in the second position, it can also ensure that the projections of the sealing assembly 820 and the first socket 610 and the second socket 710 in the first direction X do not overlap, so that the sealing assembly 820 can avoid the first socket 610 and the second socket 710. Therefore, the sealing mechanism 800 can be disassembled to reassemble the battery 100 in the area where the battery 100 is running. The operation is simple and can improve the convenience of battery replacement, which is conducive to further improving the battery replacement efficiency of the power device 1000.

[0147] According to some embodiments of this application, referring to Figures 5, 6, 9, and 10, the sealing assembly 820 may include a second sealing member 822, which is used to seal the second socket 710. The mounting base 500 has a second clearance groove 530 on the side facing the sealing assembly 820 in the first direction X. When the sealing assembly 820 is in the second position, the second sealing member 822 is disposed opposite to the second clearance groove 530 along the first direction X, and the second clearance groove 530 is used to accommodate at least a portion of the second sealing member 822.

[0148] The blocking assembly 820 may include a second blocking member 822, which is used to block the second socket 710. That is, the blocking assembly 820 has a second blocking member 822 for blocking the second socket 710 of the second connector 700, so that when the driving unit 810 drives the blocking assembly 820 to move along the first direction X toward the direction close to the second socket 710, the second blocking member 822 can block the second socket 710.

[0149] When the sealing assembly 820 is in the second position, the second sealing member 822 is disposed opposite to the second clearance groove 530 along the first direction X. The second clearance groove 530 is used to accommodate at least a portion of the second sealing member 822. That is, when the sealing assembly 820 is in the second position, the projection of the second sealing member 822 of the sealing assembly 820 in the first direction X is located in the second clearance groove 530, so that when the driving unit 810 drives the sealing assembly 820 to move along the first direction X toward the mounting base 500, the second sealing member 822 can be inserted into the second clearance groove 530, so that the second clearance groove 530 can accommodate at least a portion of the second sealing member 822.

[0150] For example, in this embodiment, the second sealing member 822 is made of rubber. By making the material of the second sealing member 822 rubber, the second sealing member 822 has a certain elastic deformation capability. On the one hand, this reduces the rigid contact between the second sealing member 822 and the second connector 700, which helps to reduce the risk of the second sealing member 822 damaging the second connector 700. On the other hand, it enables the second sealing member 822 to be pressed tightly onto the second socket 710 of the second connector 700, which helps to further improve the effect of the second sealing member 822 in sealing the second socket 710 of the second connector 700.

[0151] In this embodiment, the sealing assembly 820 is provided with a second sealing member 822 for sealing the second socket 710. A second clearance groove 530 is provided on the side of the mounting base 500 facing the sealing assembly 820 along the first direction X. When the sealing assembly 820 is in the second position, the second sealing member 822 of the sealing assembly 820 can be positioned opposite to the second clearance groove 530 in the first direction X. This allows the first driving member 811 of the driving unit 810 to also drive the sealing assembly 820 in the second position towards the mounting base 500 along the first direction X. The direction is shifted so that at least a portion of the first sealing member 821 can be accommodated in the first clearance groove 520, while at least a portion of the second sealing member 822 can be accommodated in the second clearance groove 530. This reduces the space occupied by the sealing assembly 820 on the side of the mounting base 500 for assembling the battery 100 in the first direction X. This further reduces the interference between the sealing assembly 820 and the battery 100 when reassembling the battery 100 in the area where the battery 100 is operating, thus facilitating the reassembly of the battery 100.

[0152] In some embodiments, as shown in Figures 4 and 6, a second protrusion 550 is formed on the side of the mounting base 500 opposite to the sealing assembly 820 and corresponding to the position of the second clearance groove 530 along the first direction X.

[0153] For example, the second clearance groove 530 provided on the side of the mounting base 500 facing the sealing assembly 820 is formed by a stamping process, so that the second clearance groove 530 is formed on the side of the mounting base 500 facing the sealing assembly 820, and a second protrusion 550 is formed on the side of the mounting base 500 away from the sealing assembly 820 at a position corresponding to the first clearance groove 520. Of course, the processing method of the second clearance groove 530 provided on the side of the mounting base 500 facing the sealing assembly 820 is not limited to this. In other embodiments, the second clearance groove 530 provided on the side of the mounting base 500 facing the sealing assembly 820 can also be formed by a processing process such as casting or milling.

[0154] In this embodiment, by forming a second protrusion 550 on the side of the mounting base 500 away from the sealing assembly 820 along the first direction X and at the position corresponding to the second clearance groove 530, the second clearance groove 530 is a structure that can be formed on the mounting base 500 by a stamping process, which helps to reduce the difficulty of forming the second clearance groove 530 on the mounting base 500 and helps to improve the processing efficiency of the second clearance groove 530.

[0155] According to some embodiments of this application, referring to Figures 5, 7, and 8, the sealing assembly 820 includes a first sealing member 821, which is used to seal the first socket 610. The first sealing member 821 may include a first body portion 8211 and a first plug 8212. The first body portion 8211 has a first surface 8211a, which is used to cover the first socket 610. The first plug 8212 protrudes from the first surface 8211a and is used to be inserted into the first socket 610.

[0156] The first body portion 8211 has a first surface 8211a, which is used to cover the first socket 610. That is, the first body portion 8211 has a first surface 8211a facing the mounting base 500 in the first direction X. When the first sealing member 821 blocks the first socket 610, the first connector 600 forms a structure in which one end of the first socket 610 abuts against the first surface 8211a, so that the first surface 8211a covers the first socket 610. That is, the first surface 8211a covers the first socket 610 of the first connector 600, and the projection of the first socket 610 in the first direction X is located within the first surface 8211a.

[0157] The first plug 8212 protrudes from the first surface 8211a and is used to be inserted into the first socket 610. That is to say, the first plug 8212 is a protruding structure protruding from the first surface 8211a of the first body part 8211, and when the first surface 8211a covers the first socket 610, the first plug 8212 is inserted into the first socket 610.

[0158] For example, in Figure 5, the first body portion 8211 and the first plug 8212 are integrally formed, that is, the first body portion 8211 and the first plug 8212 are integral structures, and both the first body portion 8211 and the first plug 8212 are made of rubber. Of course, in other embodiments, the first body portion 8211 and the first plug 8212 can also be separate structures, that is, the first body portion 8211 and the first plug 8212 are separate structures, and the first plug 8212 can be connected to the first body portion 8211 by means of adhesive, bolting, or snap-fit ​​and protrude from the first surface 8211a.

[0159] In this embodiment, the first sealing member 821 is provided with a first body portion 8211 and a first plug 8212 protruding from the first surface 8211a of the first body portion 8211. When the first sealing member 821 seals the first socket 610, the first surface 8211a of the first body portion 8211 can cover the first socket 610, and the first plug 8212 can be inserted into the first socket 610, so as to achieve double sealing of the first socket 610 by the first body portion 8211 and the first plug 8212 of the first sealing member 821, thereby improving the sealing effect of the first sealing member 821 on the first socket 610.

[0160] According to some embodiments of this application, referring to Figures 4, 5, 7, and 8, the electrical device 1000 may further include a second connector 700 having a second socket 710. The second connector 700 is used for fluid connection with the battery 100, and the first connector 600 is used for electrical connection with the battery 100. The drive unit 810 is configured to drive the sealing assembly 820 to simultaneously seal the first socket 610 and the second socket 710 or simultaneously open the first socket 610 and the second socket 710.

[0161] In this embodiment, the power device 1000 is also provided with a second connector 700. The second connector 700 and the first connector 600 are used for fluid connection and electrical connection with the battery 100, respectively, so as to realize the electrical connection between the battery 100 and the power system of the power device 1000 and the water circuit connection of the cooling system. The driving unit 810 can drive the sealing component 820 to simultaneously seal or open the first socket 610 of the first connector 600 and the second socket 710 of the second connector 700, thereby achieving simultaneous sealing of the first connector 600 and the second connector 700. On the one hand, the sealing mechanism 800 protects both the first connector 600 and the second connector 700, reducing the risk of damage to both the first connector 600 and the second connector 700. On the other hand, it can further reduce manual intervention, and the automatic sealing of the first connector 600 and the second connector 700 of the power device 1000 can be achieved without manual intervention, thereby improving the automation level of battery swapping of the power device 1000.

[0162] According to some embodiments of this application, referring to Figures 5, 7, and 8, the sealing assembly 820 includes a second sealing member 822, which is used to seal the second socket 710. The second sealing member 822 may include a second body portion 8221 and a second plug 8222. The second body portion 8221 has a second surface 8221a, which is used to cover the second socket 710. The second plug 8222 protrudes from the second surface 8221a and is used to be inserted into the second socket 710.

[0163] The second body portion 8221 has a second surface 8221a, which is used to cover the second socket 710. That is, the second body portion 8221 has a second surface 8221a facing the mounting base 500 in the first direction X. When the second sealing member 822 blocks the second socket 710, the second connector 700 forms a structure where one end of the second socket 710 abuts against the second surface 8221a, so that the second surface 8221a covers the second socket 710. That is, the second surface 8221a covers the second socket 710 of the second connector 700, and the projection of the second socket 710 in the first direction X is located within the second surface 8221a.

[0164] The second plug 8222 protrudes from the second surface 8221a and is used to be inserted into the second socket 710. That is, the second plug 8222 is a protruding structure protruding from the second surface 8221a of the second body part 8221, and when the second surface 8221a covers the second socket 710, the second plug 8222 is inserted into the second socket 710.

[0165] For example, in Figure 5, the second body portion 8221 and the second plug 8222 are integrally formed structures, that is, the second body portion 8221 and the second plug 8222 are integral structures, and both the second body portion 8221 and the second plug 8222 are made of rubber. Of course, in other embodiments, the second body portion 8221 and the second plug 8222 can also be separate structures, that is, the second body portion 8221 and the second plug 8222 are separate structures, and the second plug 8222 can be connected to the second body portion 8221 by means of adhesive, bolting, or snap-fit ​​and protrude from the second surface 8221a.

[0166] It should be noted that, as shown in Figure 9, the second connector 700 is used for fluid connection with the battery 100, and the second connector 700 is connected to the cooling system of the electrical device 1000, so that the second connector 700 has two second sockets 710. One second socket 710 is used for fluid to flow into the battery 100, and the other second socket 710 is used for fluid to flow out of the battery 100. Correspondingly, as shown in Figure 5, the second sealing member 822 includes two second plugs 8222. Both second plugs 8222 are protruding on the second surface 8221a. The second surface 8221a is used to simultaneously cover the two second sockets 710 of the second connector 700. The two second plugs 8222 are respectively used to be inserted into the two second sockets 710 of the second connector 700.

[0167] In this embodiment, the second sealing member 822 is provided with a second body portion 8221 and a second plug 8222 protruding from the second surface 8221a of the second body portion 8221. When the second sealing member 822 seals the second socket 710, the second surface 8221a of the second body portion 8221 can cover the second socket 710, and the second plug 8222 can be inserted into the second socket 710, so as to achieve double sealing of the second socket 710 by the second body portion 8221 and the second plug 8222, thereby improving the sealing effect of the second sealing member 822 on the second socket 710.

[0168] According to some embodiments of this application, referring to Figures 5, 7, 8, and 9, the first socket 610 and the second socket 710 are located on the same side of the mounting base 500 in the first direction X. The blocking mechanism 800 may further include a connecting shaft 840 passing through the mounting base 500 along the first direction X. The connecting shaft 840 connects the drive unit 810 and the blocking assembly 820. Along the first direction X, the drive unit 810 is mounted on the side of the mounting base 500 opposite to the first socket 610 and the second socket 710, and the blocking assembly 820 is located on the side of the mounting base 500 opposite to the drive unit 810.

[0169] The first socket 610 and the second socket 710 are located on the same side of the mounting base 500 in the first direction X, that is, the first socket 610 and the second socket 710 are respectively used for the first plug and the second plug to be inserted from the same side of the mounting base 500 along the first direction X.

[0170] The connecting shaft 840 passes through the mounting base 500 along the first direction X. The connecting shaft 840 connects the drive unit 810 and the sealing assembly 820. That is, the mounting base 500 has mounting holes that pass through both sides of the mounting base 500 along the first direction X. The connecting shaft 840 passes through the mounting holes along the first direction X. Both ends of the connecting shaft 840 extend out of the mounting holes, and both ends of the connecting shaft 840 are connected to the sealing assembly 820 and the drive unit 810, respectively.

[0171] Along the first direction X, the drive unit 810 is mounted on the side of the mounting base 500 away from the first socket 610 and the second socket 710, and the sealing component 820 is located on the side of the mounting base 500 away from the drive unit 810. That is, the drive unit 810 and the sealing component 820 are located on opposite sides of the mounting base 500 in the first direction X, and the sealing component 820, the first socket 610 and the second socket 710 are all located on the same side of the mounting base 500 in the first direction X.

[0172] In this embodiment, by setting the first socket 610 of the first connector 600 and the second socket 710 of the second connector 700 to be located on the same side of the mounting base 500 in the first direction X, the driving unit 810 can drive the sealing assembly 820 to simultaneously seal the first socket 610 and the second socket 710, which helps to reduce the difficulty of the sealing assembly 820 simultaneously sealing the first socket 610 and the second socket 710. By placing the drive unit 810 and the sealing assembly 820 on opposite sides of the mounting base 500 in the first direction X, and connecting the drive unit 810 and the sealing assembly 820 via the connecting shaft 840, the drive unit 810 is installed on the side of the mounting base 500 away from the first socket 610 and the second socket 710. This helps to save space occupied by the sealing mechanism 800 on the side of the mounting base 500 where the battery 100 is installed. It also helps to reduce interference between the sealing mechanism 800 and the battery 100 when reassembling the battery 100 in the area where the battery 100 is running, thus facilitating the reassembly of the battery 100.

[0173] According to some embodiments of this application, referring to Figures 5, 7, and 8, the sealing assembly 820 may include a first sealing element 821, a second sealing element 822, and a connector 823. Both the first sealing element 821 and the second sealing element 822 are disposed on the side of the connector 823 facing the mounting base 500. A drive unit 810 is connected to the connector 823 and is configured to drive the connector 823 to move relative to the mounting base 500, thereby causing the first sealing element 821 and the second sealing element 822 to respectively seal the first socket 610 and the second socket 710 or respectively open the first socket 610 and the second socket 710.

[0174] The first sealing member 821 and the second sealing member 822 are both disposed on the side of the connector 823 facing the mounting base 500, that is, the first sealing member 821 and the second sealing member 822 are both connected to the side of the connector 823 facing the mounting base 500 in the first direction X.

[0175] For example, the structure by which the first sealing member 821 and the second sealing member 822 are connected to the connector 823 can be varied, such as by bonding or bolting.

[0176] It should be noted that in the implementation where the sealing mechanism 800 includes a connecting shaft 840, and the connecting shaft 840 connects the drive unit 810 and the sealing assembly 820, the connecting shaft 840 is connected to the connector 823 of the sealing assembly 820.

[0177] In this embodiment, the blocking assembly 820 is provided with a connector 823 and a first blocking member 821 and a second blocking member 822 disposed on the connector 823. By disposing the first blocking member 821 and the second blocking member 822 on the side of the connector 823 facing the mounting base 500 in the first direction X, and connecting the connector 823 to the drive unit 810, the drive unit 810 can drive the connector 823 to move relative to the mounting base 500, so as to further drive the first blocking member 821 and the second blocking member 822 to block the first socket 610 and the second socket 710 respectively. The blocking mechanism 800 with this structure can reduce the difficulty of the blocking assembly 820 to block the first socket 610 and the second socket 710 at the same time, and can improve the stability and reliability of the blocking assembly 820 to block the first socket 610 and the second socket 710 at the same time.

[0178] In some embodiments, referring to FIG5, the connector 823 has a first end 8231 and a second end 8232 opposite to each other in its extending direction. A first sealing member 821 is disposed at the first end 8231, and a second sealing member 822 is disposed at the second end 8232. The connection position between the connector 823 and the drive unit 810 is located between the first end 8231 and the second end 8232 of the connector 823.

[0179] It should be noted that in the implementation where the sealing mechanism 800 includes a connecting shaft 840 and the connecting shaft 840 connects the drive unit 810 and the sealing assembly 820, the connection position between the connector 823 and the connecting shaft 840 is located between the first end 8231 and the second end 8232 of the connector 823.

[0180] In this embodiment, by disposing the first sealing member 821 and the second sealing member 822 on the first end 8231 and the second end 8232 of the connector 823 opposite to each other in its extension direction, and by setting the connection position between the connector 823 and the drive unit 810 between the first end 8231 and the second end 8232 of the connector 823, the connection position between the drive unit 810 and the connector 823 is located between the first sealing member 821 and the second sealing member 822. This is beneficial to improving the stability of the drive unit 810 driving the connector 823 to move relative to the mounting base 500, and also beneficial to improving the force balance of the connector 823 when the first sealing member 821 and the second sealing member 822 block the first socket 610 and the second socket 710 respectively.

[0181] According to some embodiments of this application, referring to Figures 4, 5, 7, and 8, and further referring to Figure 11, Figure 11 is a flowchart illustrating a control method for an electrical device 1000 provided in some embodiments of this application. This application also provides a control method for an electrical device 1000, applicable to any of the above-described electrical devices 1000. The control method for the electrical device 1000 includes:

[0182] Receive control signals;

[0183] If the control signal is a blocking signal, then the first action is executed, which is to control the drive unit 810 to drive the blocking component 820 to block the first socket 610;

[0184] If the control signal is an open signal, then the second action is executed, which is to control the drive unit 810 to drive the sealing component 820 to open the first socket 610.

[0185] Referring to Figure 4, the electrical device 1000 may further include a control module 900, which is electrically connected to the drive unit 810 of the blocking mechanism 800. The control module 900 receives a control signal, judges the control signal, and controls the execution of a first action or a second action based on the judgment result, thereby controlling the drive unit 810 to drive the blocking assembly 820 to block or open the first socket 610. The control module 900 may be a PLC controller 200, etc. The specific structure of the control module 900 can be found in related technologies and will not be described in detail here.

[0186] It should be noted that in the implementation where the electrical device 1000 also includes a second connector 700 and the second connector 700 has a second socket 710, the first action is to control the drive unit 810 to drive the blocking component 820 to simultaneously block the first socket 610 and the second socket 710. Similarly, the second action is to control the drive unit 810 to drive the blocking component 820 to simultaneously open the first socket 610 and the second socket 710.

[0187] In this embodiment, the power device 1000 can execute a first action and a second action according to different control signals after receiving a control signal, so as to control the drive unit 810 to drive the blocking component 820 to block or open the first socket 610. This enables the blocking mechanism 800 to automatically block or open the first socket 610 under different usage conditions of the power device 1000, which is beneficial to improve the automation level of the power device 1000, reduce manual intervention, and reduce the failure rate caused by manual operation. This is beneficial to improve the battery swapping efficiency of the power device 1000 and reduce the battery swapping cost of the power device 1000.

[0188] According to some embodiments of this application, referring to FIG11, the first action may include:

[0189] Step S110: Control drive unit 810 drives sealing assembly 820 to rotate around the axis extending along the first direction X to the first position. The sealing assembly 820 in the first position is positioned opposite to the first socket 610 in the first direction X (as shown in Figure 8).

[0190] Step S120: Control drive unit 810 drives sealing assembly 820 to move along the first direction X toward the mounting base 500, so that sealing assembly 820 blocks first socket 610 (as shown in Figures 6 and 7).

[0191] In step S110, the control drive unit 810 drives the sealing assembly 820 to rotate from the second position to the first position along the axis extending in the first direction X, so that the first direction X of the sealing assembly 820 is positioned opposite to the first socket 610 in the first direction X.

[0192] Step S120 involves the control drive unit 810 driving the sealing assembly 820 located in the first position to move along the first direction X toward the mounting base 500, so that the first sealing element 821 of the sealing assembly 820 seals the first socket 610.

[0193] It should be noted that in an implementation where the electrical device 1000 also includes a second connector 700, and the second connector 700 has a second socket 710, then after executing step S110, the second sealing member 822 of the sealing assembly 820 can be positioned opposite to the second socket 710 in the first direction X. Similarly, after executing step S120, the sealing assembly 820 located in the first position can be moved along the first direction X towards the mounting base 500, so that the second sealing member 822 of the sealing assembly 820 blocks the second socket 710.

[0194] In this embodiment, when the control drive unit 810 drives the blocking component 820 to block the first socket 610, the control drive unit 810 first drives the blocking component 820 to rotate to a first position that is opposite to the first socket 610 in the first direction X, and then controls the drive unit 810 to drive the blocking component 820 to move along the first direction X towards the mounting base 500 to block the first socket 610. The control logic is simple, easy to implement, and helps to improve the reliability of the blocking mechanism 800 in blocking the first socket 610.

[0195] In some embodiments, please continue to refer to Figure 11, before step S110, the first action may further include:

[0196] Step S130: Control drive unit 810 drives sealing assembly 820 to move away from mounting base 500 along first direction X, so that sealing assembly 820 is spaced apart from first connector 600 in first direction X (as shown in Figure 9).

[0197] After step S130 is executed, the blocking component 820 can be driven by the driving unit 810 to move along the first direction X in a direction away from the mounting base 500 to the second position.

[0198] It should be noted that, referring to Figures 9 and 10, in the embodiment where the mounting base 500 is provided with a first clearance groove 520, step S130 is to drive the first blocking member 821 of the blocking assembly 820 to exit from the first clearance groove 520 along the first direction X and move to the second position. That is, the blocking assembly 820 of the blocking mechanism 800 is moved from the position shown in Figure 10 to the position shown in Figure 9 along the first direction X.

[0199] It should be noted that in the implementation where the electrical device 1000 also includes a second connector 700, the second connector 700 has a second socket 710, and the mounting base 500 is provided with a second clearance groove 530, then executing step S130 can also cause the second blocking member 822 of the blocking assembly 820 to exit from the second clearance groove 530 along the first direction X and move to the second position.

[0200] In this embodiment, before the control drive unit 810 drives the sealing assembly 820 to rotate around the axis extending along the first direction X to the first position, the control drive unit 810 can first drive the sealing assembly 820 to move away from the mounting base 500 along the first direction X, so that the sealing assembly 820 can be spaced apart from the first connector 600 in the first direction X. This reduces interference or collision between the sealing assembly 820 and the first connector 600 during the process of the drive unit 810 driving the sealing assembly 820 to the first position, thereby helping to alleviate the phenomenon of damage to the first connector 600 or the inability of the sealing assembly 820 to rotate smoothly to the first position.

[0201] According to some embodiments of this application, as shown in Figure 11, the second action may include:

[0202] Step S210: Control drive unit 810 drives sealing assembly 820 to move away from mounting base 500 along the first direction X, so that sealing assembly 820 opens first socket 610;

[0203] Step S220: Control drive unit 810 drives sealing assembly 820 to rotate around the axis extending along the first direction X to the second position, where the sealing assembly 820 in the second position does not overlap with the projection of the first socket 610 in the first direction X.

[0204] In step S210, the control drive unit 810 drives the sealing assembly 820 to move along the first direction X away from the mounting base 500 to the first position, so that the first sealing member 821 of the sealing assembly 820 opens the first socket 610 (as shown in Figure 8).

[0205] Step S220 involves controlling the drive unit 810 to drive the sealing assembly 820 to rotate from the first position to the second position around the axis extending along the first direction X, so that the projections of the first sealing member 821 and the first socket 610 of the sealing assembly 820 in the first direction X do not overlap (as shown in Figure 9).

[0206] It should be noted that in an implementation where the electrical device 1000 also includes a second connector 700, and the second connector 700 has a second socket 710, then after executing step S210, the second sealing member 822 of the sealing assembly 820 can also open the second socket 710. Similarly, after executing step S220, the projections of the second sealing member 822 of the sealing assembly 820 and the second socket 710 in the first direction X can also be made so that they do not overlap.

[0207] In this embodiment, when the control drive unit 810 drives the sealing component 820 to open the first socket 610, the control drive unit 810 first drives the sealing component 820 to move away from the mounting base 500 along the first direction X, so that the sealing component 820 disengages from the first socket 610. Then, the control drive unit 810 drives the sealing component 820 to rotate to a second position where its projection on the first socket 610 in the first direction X does not overlap. The control logic is simple and easy to implement. While opening the first socket 610, the sealing component 820 can also avoid the first socket 610. Therefore, the reassembly of the battery 100 in the area where the battery 100 operates can be achieved without disassembling the sealing mechanism 800. The degree of automation is high, no manual intervention is required, and the convenience of battery swapping can be improved. This is conducive to further improving the battery swapping efficiency of the power device 1000 and further reducing the battery swapping cost of the power device 1000.

[0208] In some embodiments, please continue to refer to Figure 11, after step S220, the second action may further include:

[0209] Step S230: Control drive unit 810 drives sealing assembly 820 to move along the first direction X toward the mounting base 500 (as shown in Figure 10).

[0210] After step S230 is executed, the blocking component 820 can be driven by the driving unit 810 to move from the second position along the first direction X toward the mounting base 500.

[0211] It should be noted that, referring to Figures 9 and 10, in the embodiment where the mounting base 500 is provided with a first clearance groove 520, step S230 is to drive the first blocking member 821 of the blocking assembly 820 to move from the second position along the first direction X toward the mounting base 500 and insert it into the first clearance groove 520. That is, the blocking assembly 820 of the blocking mechanism 800 moves from the position shown in Figure 9 to the position shown in Figure 10 along the first direction X.

[0212] It should be noted that in the implementation where the electrical device 1000 also includes a second connector 700, the second connector 700 has a second socket 710, and the mounting base 500 is provided with a second clearance groove 530, then executing step S230 can also cause the second blocking member 822 of the blocking assembly 820 to move from the second position along the first direction X toward the direction close to the mounting base 500 and be inserted into the second clearance groove 530.

[0213] In this embodiment, after the control drive unit 810 drives the sealing assembly 820 to rotate around the axis extending along the first direction X to the second position, it can also control the drive unit 810 to drive the sealing assembly 820 to move along the first direction X towards the mounting base 500, so that the sealing assembly 820 can share part of the space with the first connector 600 in the first direction X. This is beneficial to further reduce the interference between the sealing assembly 820 and the battery 100 when reassembling the battery 100 in the area where the battery 100 is running, so as to facilitate the reassembly of the battery 100.

[0214] According to some embodiments of this application, referring to Figures 1 to 10, this application provides an electrical device 1000, which includes a mounting base 500, a first connector 600, a second connector 700, and a sealing mechanism 800.

The drive unit 810 includes a first drive member 811, a second drive member 812, and a movable seat 813. The first drive member 811 is mounted on the side of the mounting base 500 facing away from the sealing assembly 820 in the first direction X.

The output end of 2 is connected to the connecting shaft 840. The second driving member 812 is configured to drive the sealing assembly 820 to rotate between a first position and a second position about an axis extending along the first direction X. When the sealing assembly 820 is in the first position, the first driving member 811 can drive the sealing assembly 820 to move along the first direction X and seal the first socket 610 and the second socket 710. When the sealing assembly 820 is in the second position, the projections of the first socket 610 and the second socket 710 in the first direction X do not overlap with the sealing assembly 820. The elastic member 830 is sleeved on the outside of the connecting shaft 840. Along the first direction X, the elastic member 830 is compressed between the second driving member 812 and the mounting base 500, and the two ends of the elastic member 830 abut against the second driving member 812 and the mounting base 500, respectively.The sealing assembly 820 includes a first sealing member 821, a second sealing member 822, and a connector 823. Both the first sealing member 821 and the second sealing member 822 are disposed on the side of the connector 823 facing the mounting base 500. The first sealing member 821 is used to seal the first socket 610, and the second sealing member 822 is used to seal the second socket 710. The connector 823 is connected to the connecting shaft 840.
