[0048] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, with reference to the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0049] Embodiment 1

[0050] As Figures 1 to 3As shown in the figure, this embodiment provides a mobile power rental device, which includes a host 1 and at least one charging cabinet unit 2. The charging cabinet unit includes a battery compartment 21, a charging terminal 22, a power input terminal 23, a power output terminal 24, a circuit board 25, and an adapter 26. The battery compartment is one or more. A number of mobile power supplies 3 are placed in the battery compartment 21. When the mobile power supply 3 is located in the battery compartment 21, the charging terminal 22 can charge the mobile power supply 3. The power input terminal 23 of one charging cabinet unit 2 is electrically connected to a power socket. The current input through the power input terminal 23 can be output from the power output terminal 24 to the power input terminal 23 of another mobile power rental device. The adapter 26 is respectively connected to the power input terminal 23 and the circuit board 25. The power input end (not shown in the figure) of the adapter 26 is electrically connected to the power input terminal 23, and the power output end (not shown in the figure) of the adapter 26 is electrically connected to the circuit board 25. The charging terminal 22 is electrically connected to the circuit board 25. The circuit board 25 can output direct current to the charging terminal 22 for charging the mobile power supply 3. The host 1 is electrically connected to the charging cabinet unit 2. The host 1 can send control signals to the charging cabinet unit 2 to control the charging cabinet unit 2 through wired or wireless communication. The host 1 and the charging cabinet unit 2 are detachably stacked vertically, and the host 1 and the charging cabinet unit 2 are electrically connected through the power output terminal 24 or the power input terminal 23 of the charging cabinet unit 2. Adjacent charging cabinet units 2 are electrically connected through the power output terminal 24 of one and the power input terminal 23 of the other. After the power is input through the power input terminal 23 of one charging cabinet unit 2, through the cooperation of the power output terminal 24 or several power output terminals 24 and power input terminals 23, current is supplied to several charging cabinet units 2 and the host 1. Through the cooperation of the power input terminal 23 and the power output terminal 24 of the charging cabinet unit 2 of the present invention, the stacked arrangement of multiple charging cabinet units 2 can be realized. Moreover, when the number of charging cabinet units 2 is increased, there is no need to increase the number of power sockets and power charging cables. The number of stacked charging cabinet units is not limited by the number of power sockets and / or the length of the power charging cables, which saves the manufacturing cost. At the same time, since the way of increasing the number is to stack upwards, there is no need to increase the floor area.

[0051] In this embodiment, the host 1 is arranged at the uppermost part of the charging cabinet unit 2, which is convenient for the renter of the mobile power supply 3 to scan the code for unlocking. One or more charging cabinet units 2 are stacked below the host 1. The power charging cable is electrically connected to the power input terminal 23 of the lowermost charging cabinet unit 2. Through the cooperation between the power input terminals 23 and the power output terminals 24 of each charging cabinet unit 2, current can be transmitted to other charging cabinet units 2 and the host 1. Each charging cabinet unit 2 forms a parallel relationship, and the voltages of each charging cabinet unit 2 are the same, which is beneficial to stably supply current to the adapter 26 and the circuit board 25 and ensure the charging of the mobile power supply 3.

[0052] As a preference, the power supply is the commercial power, and the commercial power is alternating current with a voltage generally of 100 - 240V. The commercial power input through the power input terminal 23 of the charging cabinet unit 2 is output to the power input terminal 23 of another charging cabinet unit 2 through the power output terminal 24, that is, both the power input terminal 23 and the power output terminal 24 transmit alternating current. The adapter 26 has the function of converting alternating current into direct current, and can convert the alternating current of the power input terminal 23 into direct current and output it to the circuit board 25. In other embodiments, the power supply can also be 380V industrial power or direct current.

[0053] As Figure 2 and Figure 3 shown, the charging cabinet unit 2 further includes a housing 27. The power output terminal 24 is a power output female socket, and one end of the power output female socket extends out of the housing 27. An insulating layer 241 is provided outside the conductor part of the power output female socket, and the insulating layer 241 extends along the direction of the conductor to wrap the conductor in the insulating layer 241, avoiding electric shock when the staff touches the conductor by mistake when adding conductors to the charging cabinet, and improving the safety performance of the equipment. The power input terminal 23 is a power input male head. A receiving cavity 231 corresponding to the position of the power output female socket is provided at the other end of the housing 27. The receiving cavity 231 corresponds to the power output female socket, and the power input male head is arranged in the receiving cavity 231. The receiving cavity 231 is recessed into the housing 27, and it is not easy for the staff to touch the power input terminal 23 during handling or installation, effectively eliminating the hidden danger of accidental electric shock. The power output female socket is used to be clamped in the receiving cavity 231 of another charging cabinet unit 2 and inserted into the power input male head in the receiving cavity 231 when two charging cabinet units 2 are spliced, so as to realize the current transmission between the two charging cabinet units 2. The setting of the receiving cavity 231 and the power output female socket also plays a role in fixing the connection between the host 1 and the charging cabinet unit 2 or between the charging cabinet units 2.

[0054] As a preference, as Figure 2 and Figure 3As shown in the figure, the upper surface and the lower surface of the charging cabinet unit 2 are provided with a detachable first mounting plate 201 and a second mounting plate 202. The first mounting plate 201 is used to fix the female power output socket, and the second mounting plate 202 is used to fix the male power input plug. The first mounting plate 201 and the second mounting plate 202 can be detachably connected to the charging cabinet unit 2 by means of snap connection, threaded connection, etc. Since the power cord plug standards vary among countries in the world, when the mobile power rental device enters other countries, it is necessary to replace the corresponding female power output socket and male power input plug. By setting the first mounting plate 201 and the second mounting plate 202 to be detachable, when replacing the female power output socket and the male power input plug, only need to remove the first mounting plate 201 and the second mounting plate 202, then the female power output socket and the male power input plug connected to the mounting plate 20 can be taken out, and then the female power output socket and the male power input plug with different standards can be assembled onto the charging cabinet unit 2, so as to efficiently and economically realize the component replacement of the mobile power rental device.

[0055] As Figure 2 and Figure 3 shown in the figure, one end of the housing 27 of the charging cabinet unit 2 is provided with a positioning convex block 271, and the other end is provided with a positioning groove 272 corresponding to the position of the positioning convex block 271. The positioning convex block 271 is used to be clamped in the positioning groove 272 of the housing of another charging cabinet unit 2 when two charging cabinet units 2 are spliced. The mainframe 1 is also provided with a positioning groove 272 or a positioning convex block 271 corresponding to the positioning convex block 271 or the positioning groove 272 of the adjacent charging cabinet unit 2. The cooperation of the positioning convex block 271 and the positioning groove 272 not only provides a guiding function for the installation of the mainframe 1 and the charging cabinet unit 2, but also plays a role in fixing the connection relationship between the adjacent mainframe 1 and the charging cabinet unit 2 and between the charging cabinet units 2.

[0056] As a preference, the positioning convex block 271 includes a main positioning convex block 2711 located at the middle position of one end of the housing 27 and a secondary positioning convex block 2712 located away from the middle position. The positioning groove 272 includes a main positioning groove 2721 and a secondary positioning groove 2722 corresponding to the positions of the main positioning convex block 2711 and the secondary positioning convex block 2712. The main positioning convex block 2711 and the secondary positioning convex block 2712 are both provided at the lower end of the housing 27, and the protruding height of the secondary positioning convex block 2712 or the total height after adding a foot pad on the secondary positioning convex block 2712 is greater than the protruding height of the main positioning convex block 2711. There are four secondary positioning convex blocks 2712 for each charging cabinet unit 2, and the secondary positioning convex blocks 2712 of the lowermost charging cabinet unit 2 can be used as support feet to support other charging cabinet units 2 and the mainframe 1 stacked on it.

[0057] As a preference, the positioning bump 271 further includes a side positioning bump 2713 located at the edge position of one end of the housing 27, the positioning groove 272 is a side positioning groove 273 provided at the other end of the housing, and the side positioning groove 273 penetrates through the end face of the housing 27 and the side wall of the housing 27 at the same time. The provision of the side positioning bump 2713 and the side positioning groove 2723 can provide a guiding function for the installation of the charging cabinet unit 2. A wiring groove 273 communicating the accommodation cavity 231 and the side positioning groove 2723 is further provided on the housing 27 of the charging cabinet unit 2. The wiring groove 273 is used for installing a power charging wire connected to a power supply, and the power charging wire is embedded into the wiring groove 273, saving space and making the connection between the wire and the power input terminal 23 closer.

[0058] As a preference, the positioning bump 271 includes a side connection bump 2714 located at the edge position of one end of the housing 27, the positioning groove 272 is a side connection groove 2714 provided at the other end of the housing 27, and fixing holes 2715 which cooperate with each other are provided on the side connection bump 2714 and the side connection groove 2724. The fixing holes 2715 can cooperate with connecting members such as screws and bolts (not shown in the figure) to achieve the fixed connection between two adjacent charging cabinet units 2. That is, when two charging cabinet units 2 are stacked, screws, bolts and other connecting members are inserted into the fixing holes 2715 of the side connection bump 2714 and the side connection groove 2724 to achieve the mutual fixed connection of the two charging cabinet units 2, so as to prevent the charging cabinet unit 2 from falling or coming off.

[0059] Such as Figures 4 to 7As shown, the charging cabinet unit 2 further includes a module main body 28, a locking mechanism 281, and a power mechanism 29. At least two battery compartments 21 are provided on the module main body 28, and each battery compartment 21 is used to place a mobile power supply 3. Each battery compartment 21 is correspondingly configured with a locking mechanism 281, and the locking mechanism 281 can lock or unlock the mobile power supply 3 in the battery compartment 21. Preferably, the locking mechanism 281 is provided on the battery compartment 21. When the mobile power supply 3 is located in the battery compartment 21, the locking mechanism 281 can extend into the battery compartment 21 to lock the mobile power supply 3 and prevent the mobile power supply 3 from being stolen. The locking mechanism 281 can also be moved out of the battery compartment 21 to unlock the mobile power supply 3. One power mechanism 29 is correspondingly configured for every two battery compartments 21. The power mechanism 29 includes a motor 291 that can rotate forward and backward and an unlocking mechanism 292 driven by the motor 291. When the motor 291 rotates forward or backward, the unlocking mechanism 292 can respectively push the locking mechanism 281 corresponding to a battery compartment 21 to move, so as to unlock the mobile power supply 3 in this battery compartment 21. That is, when the motor 291 rotates forward, the unlocking mechanism 292 pushes one locking mechanism 281 to move, and when it rotates backward, it can push the other locking mechanism 281 to move. After the locking mechanism 281 moves out of the battery compartment 21, the locking of the mobile power supply 3 will be released, so that one motor 291 can unlock two mobile power supplies 3. After the mobile power supply 3 is unlocked, the user can take out the mobile power supply 3 from the battery compartment 21. Through the cooperation of the unlocking mechanism 292 and the motor 291, the effect that one motor 291 can unlock two mobile power supplies 3 is achieved, thereby reducing the number of motors 291 required for the battery compartment module, reducing the manufacturing cost of the mobile power supply 3 charging module, and making the overall structure more compact, with a smaller volume and weight.

[0060] Furthermore, an installation cavity 211 for installing the motor 291 is provided on the module main body 28. Fixing ears 2911 are provided at both ends of the motor 291, and the fixing ears 2911 and the outer wall of the installation cavity 211 can be fixedly connected by screws, rivets, screws, etc. By providing the installation cavity 211 on the module main body 28 to install the motor 291, the overall structure of the battery compartment module can be made more reliable and compact.

[0061] As Figures 5 to 7 shown, preferably, the unlocking mechanism 292 includes a turntable 2921 fixedly connected to the output shaft of the motor 291. The unlocking mechanism 292 is located between the two locking mechanisms 281. A pushing boss 29211 facing the locking mechanism 281 is provided on the turntable 2921. When the motor 291 rotates, the pushing boss 29211 can abut against the locking mechanism 281 to push the locking mechanism 281 to move, thereby unlocking the mobile power supply 3.

[0062] Specifically, both sides of the pushing boss 29211 are provided with pushing surfaces 292111 that are smoothly transitioned with the end surface of the turntable 2921. When the turntable 2921 rotates, the pushing surfaces 292111 gradually push the locking mechanism 281 to move so as to unlock the mobile power supply 3. The pushing surfaces 292111 are arc-shaped convex surfaces, and the protruding thickness of the arc-shaped convex surfaces gradually increases along the unlocking rotation direction of the unlocking mechanism 292. Another side of the unlocking mechanism 292 is provided with a concave cavity 292112 corresponding to the pushing surfaces 292111. The setting of the concave cavity 292112 can save the material cost of machining the unlocking mechanism 292 and reduce the weight of the unlocking mechanism 292. In other embodiments, the pushing surfaces 292111 can also be inclined surfaces.

[0063] As Figure 5 shown in the figure and Figure 9 illustrated, the locking mechanism 281 includes a locking member 2811 rotatably connected to the module main body 28. One end of the locking member 2811 is provided with a buckling portion 28111 corresponding to the position of the first through hole 212, and the other end extends to correspond to the turntable 2921. A first through hole 212 is provided on the side wall of the battery compartment 21, and the locking member 2811 corresponds to the position of the first through hole 212. A card slot 31 is provided on the mobile power supply 3 and is matched with the buckling portion 28111. When the buckling portion 28111 passes through the first through hole 212 and extends into the card slot 31, the mobile power supply 3 is locked. The pushing boss 29211 can squeeze the other end of the locking member 2811 when the turntable 2921 rotates, so that one end of the locking member 2811 provided with the buckling portion 28111 moves outwards from the card slot 31 of the mobile power supply 3 to unlock the mobile power supply 3 in the battery compartment 21.

[0064] As Figures 5 to 9As shown, the two said locking parts 2811 corresponding to the same power mechanism 29 are rotationally connected to the module main body 28 by the same shaft rod 293. A first shaft hole 28213 for placing the shaft rod 293 is provided on the battery compartment 21. The first shaft hole 28213 can fix the shaft rod 293. A second shaft hole 28112 corresponding to the shaft rod 293 is provided on the locking part 2811. The shaft rod 293 passes through the first shaft hole 28213 and the second shaft hole 28112. The pushing boss 29211 can push the locking part 2811 to rotate around the shaft rod 293. Specifically, the locking part 2811 is an L-shaped structure as a whole. The power mechanism 29 is arranged at the rear end of the module main body 28. The corner position of the L-shaped locking part 2811 is rotationally connected to the corner position of the module main body 28 through the shaft rod 293. One end of the L-shaped locking part 2811 extends to the rear end of the module main body 28 corresponding to the power mechanism 29, and the other end extends along the side of the module main body 28 so that the buckle part 28111 thereon corresponds to the first through hole 212, further realizing the structural compactness of the charging cabinet unit 2.

[0065] As Figure 4 and Figure 10 shown, the locking mechanism 281 further includes an elastic reset mechanism 283 for pushing the locking part 2811 to lock the mobile power supply 3. After the user takes out the unlocked mobile power supply 3, the elastic reset mechanism 283 can push the locking part 2811 to reset. When the user returns the mobile power supply 3, the user pushes the mobile power supply 3 into the battery compartment 21. The mobile power supply 3 first ejects the buckle part 28111 out of the battery compartment 21. When the card slot 31 of the mobile power supply 3 reaches the position corresponding to the buckle part 28111, the elastic reset mechanism 283 can push the locking part 2811 to reset again, thereby locking the mobile power supply 3.

[0066] Specifically, the elastic reset mechanism 283 includes a first push rod 2831 and a first elastic member 2832 for pushing the first push rod 2831. A first protrusion 28311 is provided on the first push rod 2831. The first protrusion 28311 is arranged around the first push rod 2831. The length of the first protrusion 28311 in the radial direction of the first push rod 2831 is greater than the diameter of the first elastic member 2832. A first mounting hole 214 corresponding to the first push rod 2831 is provided on the battery compartment 21. The diameter of the first mounting hole 214 is greater than the diameter of the first push rod 2831 and less than the diameter of the first elastic member 2832. The first push rod 2831 can extend into the battery compartment 21 through the first mounting hole 214. One end of the first elastic member 2832 and the first push rod 2831 is arranged in the first mounting hole 214, and the other end of the first push rod 2831 abuts against the locking member 2811. When the unlocking mechanism 292 pushes the locking member 2811 to move, the locking member 2811 will abut against the first push rod 2831 and push the first push rod 2831 to extend into the battery compartment 21. At the same time, the first elastic member 2832 is compressed to generate an elastic force. When the unlocking mechanism 292 resets, the first elastic member 2832 will push the locking member 2811 to reset under the action of the elastic restoring force.

[0067] As Figure 5 and Figure 6 shown, the locking mechanism 281 further includes a detection device 2812. A trigger portion 28213 is provided on the locking member 2811. When the detection device 2812 detects that the trigger portion 28213 reaches a predetermined position, the motor 291 stops rotating in the current direction. At this time, the buckle portion 28111 at the other end of the trigger portion 28213 moves out of the card slot 31 of the mobile power supply 3, and the mobile power supply 3 is unlocked. The detection device 2812 determines the position of the locking member 2811 by detecting the position of the trigger portion 28213. When the mobile power supply 3 is returned to the battery compartment 21, the mobile power supply 3 first pushes the buckle out of the battery compartment 21. When the card slot 31 of the mobile power supply 3 moves to a position corresponding to the first through hole 212, the buckle re-enters the battery compartment 21 and is snapped into the card slot 31. Therefore, during the process of returning the mobile power supply 3, the trigger portion 28213 has two actions of moving and resetting. When the user inserts paper or other hard objects into the battery compartment 21, the trigger portion 28213 cannot be reset. When the detection device 2812 detects that the trigger portion 28213 is not reset, the detection device 2812 cannot send a signal indicating that the mobile power supply 3 has been successfully returned.

[0068] Specifically, the detection device 2812 is a photoelectric switch. The detection device 2812 includes a photoelectric signal transmitter (not shown in the figure), a photoelectric signal receiver (not shown in the figure), and a detection slot 28121. The photoelectric signal transmitter can emit photoelectric signals such as laser and infrared light. The photoelectric signal transmitter and the photoelectric signal receiver are respectively disposed on both sides of the detection slot 28121. The photoelectric signal transmitter can emit an optical signal from one side of the detection slot 28121 to the other side of the detection slot 28121. The triggering portion 28213 is a light blocking plate. When the buckling portion 28111 exits the battery compartment 21, the light blocking plate enters the detection slot 28121. The light blocking plate will block the optical signal from reaching the photoelectric signal receiver on the other side of the detection slot 28121. When the photoelectric signal receiver cannot receive the optical signal emitted by the photoelectric signal transmitter, the system will determine that the power bank 3 is not successfully returned. By providing the photoelectric signal transmitter, the photoelectric signal receiver, and the detection slot 28121, the problem that illegal elements steal the power bank 3 through false return can be effectively solved, and the assembly is simple and the cost is low.

[0069] Such as Figure 11As shown, an elastic pushing mechanism 284 is further provided on the module body 28. When the unlocking mechanism 292 pushes the locking part 2811 to move, so that the buckling part 28111 is moved out of the card slot 31 of the mobile power supply 3, the end of the elastic pushing mechanism 284 can extend into the battery compartment 21 to push the mobile power supply 3 out of the battery compartment 21 by a certain distance, facilitating the user to take out the mobile power supply 3 from the battery compartment 21 without digging it out. The elastic pushing mechanism 284 includes a second push rod 2841, a second elastic member 2842 for pushing the second push rod 2841, and a fixing member 2843. One end of the second push rod 2841 extends into the battery compartment 21 from the bottom of the battery compartment 21. The fixing member 2843 and the fixing ear 2911 are simultaneously fixed on the outer wall of the installation cavity 211 by screws, rivets, screws, etc. The second elastic member 2842 is arranged between the fixing member 2843 and the second push rod 2841. The second push rod 2841 is provided with a second protrusion 28411, and the second protrusion 28411 is arranged around the second push rod 2841. The second elastic member 2842 is sleeved between the second protrusion 28411 and the fixing member 2843. A second installation hole 215 corresponding to the second push rod 2841 is provided on the battery compartment 21. The length of the second protrusion 28411 in the radial direction of the second push rod 2841 is greater than the diameter of the second installation hole 215. When the buckling part 28111 locks the mobile power supply 3, the second push rod 2841 passes through the second installation hole 215 to abut against the mobile power supply 3. At this time, the second elastic member 2842 is compressed between the second protrusion 28411 and the fixing member 2843. When the buckling part 28111 exits the card slot 31, the second elastic member 2842 releases its elastic force to push the second push rod 2841 to move, thereby pushing the mobile power supply 3 out of the battery compartment 21. Preferably, the first push rod 2831 and the second push rod 2841, and the first elastic member 2832 and the second elastic member 2842 adopt the same specifications, which is convenient for manufacturing and processing.

[0070] As Figure 6 and Figure 12As shown, the battery compartment 21 includes a narrowing compartment section (not shown in the figure) that gradually narrows along the direction in which the mobile power supply 3 is inserted into the battery compartment 11, and the first through hole 212 is provided on the side wall of the narrowing compartment section. Correspondingly, one end of the outer shell of the mobile power supply 3 is provided with a narrowing portion 32 that can indicate the return direction. The narrowing portion 32 corresponds to the narrowing compartment section, and the cross-sectional area of the narrowing portion 32 gradually decreases along the extending direction of the end where the narrowing portion 32 is located. When the user returns the mobile power supply, the user can put the mobile power supply into the battery compartment according to the return direction indicated by the narrowing portion 11. When the user returns the mobile power supply, the user can conveniently observe the narrowing portion 32 and quickly confirm which end of the mobile power supply should be put into the battery compartment first according to the return direction indicated by the narrowing portion 32, so as to smoothly return the mobile power supply to the battery compartment and improve the return efficiency of the mobile power supply.

[0071] Preferably, the first through hole 212 is provided on the side wall of the narrowing compartment section. Correspondingly, the card slot 31 of the mobile power supply is provided on the narrowing portion 32. When an illegal person wants to stretch a tool such as a hard paper sheet or a metal sheet into the battery compartment to steal the mobile power supply, it is difficult for the tool to bend to reach the position where the card slot 31 is located, thereby improving the anti-theft performance of the mobile power supply.

[0072] Embodiment 2

[0073] As Figures 1 to 6As shown in the figure, this embodiment provides a mobile power rental device, including a host 1 and at least one charging cabinet unit 2. The charging cabinet unit includes a battery compartment 21, a charging terminal 22, a power input terminal 23, a power output terminal 24, and a circuit board 25. The battery compartment is one or more. A number of mobile power supplies 3 are placed in the battery compartment 21. When the mobile power supply 3 is located in the battery compartment 21, the charging terminal 22 can charge the mobile power supply 3. The power input terminal 23 of one charging cabinet unit 2 is electrically connected to a power socket. The current input through the power input terminal 23 can be output from the power output terminal 24 to the power input terminal 23 of another mobile power rental device. The circuit board 25 is electrically connected to the power input terminal 23, and the charging terminal 22 is electrically connected to the circuit board 25. The circuit board 25 can output direct current to the charging terminal 22 for charging the mobile power supply 3. A host 1 is also provided on the charging cabinet unit 2. The host 1 is electrically connected to the charging cabinet unit 2. The host 1 can send a control signal to the charging cabinet unit 2 to control the charging cabinet unit 2 through wired or wireless communication. The host 1 and the charging cabinet unit 2 and / or the charging cabinet units 2 are detachably stacked vertically. The host 1 and the charging cabinet unit 2 are electrically connected through the power output terminal 24 or the power input terminal 23 of the charging cabinet unit 2. Adjacent charging cabinet units 2 are electrically connected through the power output terminal 24 of one and the power input terminal 23 of the other. After the power is input through the power input terminal 23 of one charging cabinet unit 2, through the cooperation of the power output terminal 24 or several power output terminals 24 and the power input terminals 23, the current is supplied to several charging cabinet units 2 and the host 1. Through the cooperation of the power input terminal 23 and the power output terminal 24 of the charging cabinet unit 2, the present invention can realize the stacked arrangement of multiple charging cabinet units 2. Moreover, when increasing the number of charging cabinet units 2, there is no need to increase the number of power sockets and power charging lines. The number of stacked charging cabinet units is not limited by the number of power sockets and / or the length of the power charging lines, saving the manufacturing cost. At the same time, because the way of increasing the number is to stack upwards, there is no need to increase the floor area.

[0074] As a preference, the power is direct current. Both the power input terminal 23 and the power output terminal 24 transmit direct current. There is no need to set an adapter between the power input terminal 23 and the circuit board 25 for power type conversion, and the direct current can be directly supplied to the circuit board 25, saving the manufacturing cost of the charging cabinet unit 2.

[0075] As Figures 2 to 3As shown, the charging cabinet unit 2 further includes a housing 27. The power output terminal 24 is a female power output socket, and one end of the female power output socket extends out of the housing 27. An insulating layer 241 is provided outside the conductor part of the female power output socket. The insulating layer 241 extends along the direction of the conductor to wrap the conductor inside the insulating layer 241, preventing staff from accidentally touching the conductor when adding conductors to the charging cabinet, thus avoiding electric shock and improving the safety performance of the device. The power input terminal 23 is a male power input plug. Another accommodating cavity 231 corresponding to the position of the female power output socket is provided at the other end of the housing 27. The accommodating cavity 231 corresponds to the female power output socket. The male power input plug is arranged in the accommodating cavity 231. The accommodating cavity 231 is recessed into the housing 27, so that it is not easy for staff to touch the power input terminal 23 during handling or installation, effectively eliminating the hidden danger of accidental electric shock. The female power output socket is used to be clamped in the accommodating cavity 231 of another charging cabinet unit 2 and plugged into the male power input plug in the accommodating cavity 231 when two charging cabinet units 2 are spliced, realizing power transmission between the two charging cabinet units 2. The arrangement of the accommodating cavity 231 and the female power output socket also plays a role in fixing the connection between the host 1 and the charging cabinet unit 2 or between the charging cabinet units 2.
