[0075] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0076] This application provides a charge / discharge assembly 100; please refer to [link / reference]. Figures 1 to 3 , Figure 1 This is a schematic diagram of the charging and discharging assembly provided in an exemplary embodiment of this disclosure; Figure 2 This is a schematic diagram of the charging and discharging assembly provided in an exemplary embodiment of the present disclosure in a charging state; Figure 3 yes Figure 2 The diagram shows the structure of the electrical plug, coupling switch, and charging / discharging gun.

[0077] The charging and discharging assembly 100 has charging state, discharging state and charging pile state.

[0078] It should be noted that the charging state refers to the input of energy into the battery from an external power source (such as an energy storage unit or the power grid). The discharging state refers to the output of energy from the battery to an external load (such as a motor or electrical equipment), or the reverse feeding of energy back into the power grid. The charging station state refers to possessing the characteristics of a charging station, efficiently and quickly delivering power to external loads.

[0079] The charging and discharging assembly 100 includes a charging and discharging gun 10 and a power strip assembly 20. The power strip assembly 20 includes a coupling switching power strip 21 and a power plug 22. In the charging state, the charging and discharging gun 10 and the power plug 22 are electrically connected, and the charging and discharging gun 10 is used to output power. In the discharging state, the charging and discharging gun 10 is used to draw power from the energy storage unit. The coupling switching power strip 21 is electrically connected to the charging and discharging gun 10 and is used to output power. In the charging pile state, the coupling switching power strip 21 is used to connect to the power supply, and the charging and discharging gun 10 is electrically connected to the coupling switching power strip 21 and is used to output power.

[0080] In the charging and discharging assembly 100 of this application embodiment, in the charging state, the charging and discharging gun 10 is electrically connected to the power plug 22, and is connected to and draws power from the power source through the power plug 22, ensuring a stable power output through the power plug 22 and the charging and discharging gun 10 sequentially. In the discharging state, the coupling switching plug 21 is electrically connected to the charging and discharging gun 10, allowing the charging and discharging gun 10 to draw power from the energy storage unit and output power through the coupling switching plug 21 to supply power to other electrical devices, achieving effective utilization and expansion of power. In the charging pile state, the power source is connected to the power source through the coupling switching plug 21, ensuring a stable power output through the coupling switching plug 21 and the charging and discharging gun 10 sequentially. Since the charging and discharging assembly 100 can flexibly switch between the charging state, discharging state, and charging pile state, it can meet the usage needs in different scenarios. In addition, since the power source is connected to the power source through the power plug 22 in the charging state and through the coupling switching plug 21 in the charging pile state, the charging and discharging assembly 100 can meet the usage needs in different scenarios. This allows for different ways of connecting the charging and discharging assembly 100 to the power source, enabling users to choose the specific method of connection based on their actual needs, thus improving the user experience.

[0081] It should be noted that the charging and discharging assembly has different charging power when it is in charging state and charging pile state, so as to meet different charging needs.

[0082] Reference Figures 3 to 6 , Figure 4 This is a structural diagram of the electrical plug, coupling switch (partial structure), and charging / discharging gun. Figure 5 yes Figure 4 A magnified view of a portion at point A shown. Figure 6This is a schematic diagram of the charging / discharging assembly in a discharging state according to an exemplary embodiment of this disclosure. The coupling switching power strip 21 includes a main body 211 and a switching part 212. The main body 211 is provided with a first insertion hole 2111. The switching part 212 is movably mounted on the main body 211. When the plug 22 is inserted into the first insertion hole 2111, it drives the switching part 212 to move, thereby switching the charging / discharging assembly 100 to a discharging state. In this way, the charging / discharging assembly 100 is automatically switched to a discharging state. This simultaneous insertion and switching improves the convenience and efficiency of operation. The main body 211 and the switching part 212 of the coupling switching power strip 21 are cleverly integrated together, maintaining both structural compactness and ensuring the reliability of the switching action. By driving the movement of the switching part 212 through the insertion of the plug 22 into the first insertion hole 2111, the switching action is triggered only when the correct plug 22 is inserted. This design prevents misoperation to a certain extent.

[0083] Continue to refer to Figure 7 and Figure 10 , Figure 7 This is a schematic diagram of a portion of the structure of the coupling switching power strip provided in an exemplary embodiment of this disclosure. Figure 8 yes Figure 7 A magnified view of a portion at point B is shown. Figure 9 This is a schematic diagram of the coupling switching connector structure when the charging / discharging assembly is in a charging state, according to an exemplary embodiment of this disclosure. Figure 10 yes Figure 9 The diagram shows a partially enlarged view at point C. The switching unit 212 is movably mounted on the main body 211 between a first position and a second position. In the first position, the charging / discharging gun 10 and the electrical plug 22 are electrically connected. In the second position, the charging / discharging gun 10 and the coupling switching strip 21 are electrically connected. Thus, the switching unit 212 can switch between the first and second positions, allowing the charging / discharging gun 10 to be electrically connected to either the electrical plug 22 or the coupling switching strip 21. This design is simple and increases the versatility and flexibility of the charging / discharging assembly 100, meeting the needs of different scenarios.

[0084] Reference Figure 8 and Figure 10In some embodiments, the charging / discharging gun 10 has a first wiring end 11, the charging / discharging plug 22 has a second wiring end 221, and the coupling switching plug 21 has a third wiring end 213, arranged at intervals along the insertion direction of the charging / discharging plug 22. When the switching part 212 is in the first position, the first wiring end 11 and the second wiring end 221 are electrically connected through the switching part 212, causing the charging / discharging assembly 100 to be in a charging state. When the switching part 212 is in the second position, the first wiring end 11 and the third wiring end 213 are electrically connected through the switching part 212, causing the charging / discharging assembly 100 to be in a discharging state. This design provides two electrical connection modes, increasing the flexibility and versatility of the charging / discharging assembly 100. The first and second positions are arranged at intervals along the insertion direction of the plug 22, which ensures that the switching part 212 can accurately connect to the first terminal 11, the second terminal 221 and the third terminal 213 during the switching process. This design also makes the charging and discharging assembly 100 compact.

[0085] It should be noted that when the switching unit 212 is in different positions, it can ensure that the unconnected wiring ends remain electrically isolated, preventing electrical short circuits or accidental conduction.

[0086] Reference Figure 8 and Figure 10 In some embodiments, the switching unit 212 includes a switching body 2121 and two electrical connecting arms 2122. The switching body 2121 is movably connected to the main body 211 between a first position and a second position. The two electrical connecting arms 2122 are respectively connected to two side walls of the switching body 2121. One of the two electrical connecting arms 2122 is used to electrically connect to the first terminal 11. When the switching body 2121 is in the first position, the other of the two electrical connecting arms 2122 is electrically connected to the second terminal 221. In this way, the charging / discharging gun 10 and the electrical plug 22 are electrically connected, so that the charging / discharging assembly 100 is in a charging state. The switching body 2121 and the third terminal 213 are spaced apart, so that the charging / discharging gun 10 is electrically disconnected from the coupling switching plug 21, avoiding short circuits and improving the safety of the charging / discharging assembly 100. When the switching body 2121 is in the second position, the other of the two electrical connecting arms 2122 is spaced apart from the second wiring end 221. This achieves electrical disconnection between the charging / discharging gun 10 and the electrical plug 22, avoiding short circuits and improving the safety of the charging / discharging assembly 100. The switching body 2121 is electrically connected to the third wiring end 213, thus achieving electrical conduction between the charging / discharging gun 10 and the electrical plug 22, putting the charging / discharging assembly 100 into a discharging state.

[0087] It should be noted that the two sidewalls of the switching body 2121 can be arranged adjacently or oppositely; specifically, this application does not limit this. Furthermore, the specific shape of the two electrical connecting arms 2122 can be set as needed; this application does not limit this. In one embodiment, the two electrical connecting arms 2122 are arranged at intervals along the insertion direction of the electrical plug 22. In other embodiments, the two electrical connecting arms 2122 can also be arranged flush.

[0088] In addition, since the switching body 2121 is movably connected to the main body 211 between the first and second positions along the insertion direction of the plug 22, this design allows the switching part 212 to switch quickly and accurately between the first and second positions, improving the switching response speed and operating efficiency of the charging and discharging assembly 100.

[0089] Reference Figure 8 and Figure 10 In some embodiments, the first terminal 11 includes a connecting body 111 and two contact arms 112 arranged opposite to and spaced apart along the insertion direction of the plug 22. Both contact arms 112 are connected to the connecting body 111. At least a portion of one of the two electrical contact arms 2122 is located between the two contact arms 112, thus providing two independent electrical contact points and increasing the reliability and flexibility of the electrical connection of the first terminal 11. Furthermore, having at least a portion of one of the two electrical contact arms 2122 located between the two contact arms 112 not only makes the charging / discharging assembly 100 more compact but also improves switching efficiency. When the switching body 2121 is in the first position, one of the two electrical contact arms 2122 is electrically connected to one of the two contact arms 112. When the switching body 2121 is in the second position, one of the two electrical contact arms 2122 is electrically connected to the other of the two contact arms 112. This allows both electrical contact arms 2122 to be electrically connected to the first terminal 11 in both the first and second positions, thus meeting different switching requirements and resulting in a simple structure.

[0090] It should be noted that during the switching process, the contact arm 112, which is not in contact with the electrical connection arm 2122, remains electrically isolated to prevent potential electrical short circuits or accidental conduction.

[0091] Reference Figure 8 and Figure 10In some embodiments, a first elastic member 40 is also included, which is elastically connected between the main body 211 and the switching part 212. The first elastic member 40 is capable of moving the switching part 212 from the second position to the first position. Thus, the introduction of the first elastic member 40 provides the switching part 212 with a continuous restoring force towards the first position. This means that, without external force, the switching part 212 tends to remain in the first position, thereby ensuring the stability and reliability of the electrical connection. Due to the holding effect of the first elastic member 40, the switching part 212 is less likely to be accidentally moved to the second position by slight touch or vibration, which reduces the risk of electrical connection interruption due to misoperation. Although the first elastic member 40 keeps the switching part 212 in the first position, when switching to the second position is required, the user only needs to apply an external force sufficient to overcome the elastic force of the first elastic member 40. This design ensures the stability of the switching while facilitating the user's switching operation. In addition, the design of the first elastic element 40 can disperse the impact force during the switching process and reduce the direct friction between the switching part 212 and the main body part 211, thereby extending the durability and service life of the component.

[0092] It should be noted that the type of the first elastic element 40 can be selected as needed. For example, the first elastic element 40 may include a spring, a rubber ring, or an elastic rope, etc. Specifically, this application does not limit this. In addition, different types and different stiffnesses of the first elastic element 40 can be selected to optimize the holding effect and operating feel of the switching part 212, depending on the specific application scenario and requirements. Specifically, this application does not limit this.

[0093] Reference Figure 8 and Figure 10 In some embodiments, the main body 211 has a through hole extending through it along the insertion direction of the plug 22. The switching body 2121 includes a first main body segment 21211, a connecting segment 21212, and a second main body segment 21213 arranged sequentially along the insertion direction of the plug 22. The first main body segment 21211 and the second main body segment 21213 are respectively disposed on both sides of the through hole. The connecting segment 21212 is disposed in the through hole, and both ends of the connecting segment 21212 extend out of the through hole and are respectively connected to the first main body segment 21211 and the second main body segment 21213. The first elastic element 40 includes a spring, which is fitted onto the connecting segment 21212, and both ends of the spring are respectively connected to the first main body segment 21211 and the second main body segment 21213. In this way, when the switching body 2121 is in the second position, the spring can apply an elastic force to the switching body 2121, so that the switching body 2121 has a tendency to move towards the first position. The structure is simple and easy to install.

[0094] In some embodiments, the resistance values ​​in the corresponding circuits of the charge / discharge assembly 100 are set differently in the charging, discharging, and charging station states. Thus, in the charging state, setting an appropriate resistance value helps limit the charging current and prevent damage to the battery due to excessive current. In the discharging state, selecting a suitable resistance value ensures a smooth and efficient battery discharge process. In the charging station state, selecting an appropriate resistance value prevents damage to the battery pack due to abnormal output voltage or current from the charging gun, improving the safety of the entire charging system. The different resistance values ​​contribute to the stable operation of the charge / discharge assembly 100 in different states.

[0095] Reference Figures 11 to 14 , Figure 11 This is a schematic diagram of the coupling switching connector structure when the charging / discharging assembly is in a discharging state, according to an exemplary embodiment of this disclosure. Figure 12 yes Figure 11 A magnified view of a portion at point D is shown. Figure 13 This is a schematic diagram of the coupling switching plug section structure when the charging and discharging assembly is in the charging pile state according to an exemplary embodiment of this disclosure. Figure 14 yes Figure 13 The diagram shows a partially enlarged view at point E. In some embodiments, the charge / discharge assembly 100 further includes a charging resistor and a discharging resistor. The assembly also includes a first resistance switching unit 50, which is mounted on the main body 211. When the switching unit 212 is in a first position, the charging resistor, the charging / discharging gun 10, and the electrical plug 22 are electrically connected, putting the charge / discharge assembly 100 into a charging state. When the switching unit 212 is in a second position, the first resistance switching unit 50 is triggered, causing the discharging resistor, the coupling switching plug 21, and the charging / discharging gun 10 to be electrically connected, putting the charge / discharge assembly 100 into a discharging state. Through the design of the first resistance switching unit 50, the charge / discharge assembly 100 can flexibly switch between charging and discharging states as needed, improving its versatility and practicality. During charging, the charging resistor limits the charging current to prevent the battery from overheating or being damaged; during discharging, the discharging resistor stabilizes the discharging current, ensuring the safe operation of the circuit. The design of the first resistance switching unit 50 enables the charging and discharging assembly 100 to automatically switch between charging and discharging resistance in different modes, thereby reducing safety hazards caused by human error or circuit failure.

[0096] It should be noted that by precisely controlling the resistance values ​​of the charging and discharging resistors, the current and voltage during the charging and discharging process can be optimized, thereby improving charging and discharging efficiency. This helps to shorten charging time, extend battery life, and reduce energy waste. Furthermore, the selection of the charging and discharging resistors needs to precisely match the characteristics of the battery and circuit to ensure optimal charging and discharging performance and safety. The optimal resistor values ​​can be determined through experimental testing or simulation analysis. Specifically, this application does not limit the magnitude of the resistance values ​​of the charging and discharging resistors.

[0097] Reference Figure 1 , Figure 3 and Figure 17 , Figure 17 This is a schematic diagram of the structure of the charging pile control module provided in an exemplary embodiment of this disclosure. In some embodiments, the charging and discharging assembly 100 further includes a charging pile control module 30, which is used to connect electrically to the power grid. The charging pile control module 30 is used to connect and cooperate with the coupling switching plug 21 to switch the charging and discharging assembly 100 to the charging pile state. Thus, with the introduction of the charging pile control module 30, the charging and discharging assembly 100 not only has charging and discharging functions, but can also be used as a charging pile, connecting electrically to the power grid to provide charging services for electric vehicles or other devices. Through the connection and cooperation of the charging pile control module 30 and the coupling switching plug 21, the charging and discharging assembly 100 can quickly switch to the charging pile state, which provides great convenience to users.

[0098] It should be noted that the electrical connection between the charging pile control module 30 and the power grid requires rigorous safety certification and testing to ensure the safety and stability of the circuit. Simultaneously, the connection with the coupling switching power strip 21 must also comply with relevant safety standards and specifications to prevent electrical fires, electric shocks, and other safety hazards.

[0099] Reference Figure 12 and Figure 14In some embodiments, the coupling switching power strip 21 further includes a first pushing part 70, which is movably mounted on the main body 211. The charging pile control module 30 includes a connection plug 32 electrically connected to the control body 31. The control body 31 is used to electrically connect to the power grid. The main body 211 is also provided with a second plug hole 2112. When the connection plug 32 is inserted into the second plug hole 2112, it can precisely drive the first pushing part 70 to move, so that the charging and discharging assembly 100 switches to the charging pile state. This design realizes the automatic switching of the charging and discharging assembly 100 from other states to the charging pile state. Users do not need to perform complicated operations or adjustments. They only need to simply insert the connection plug 32 into the second plug hole 2112, which greatly improves the convenience of use. The movable mounting of the first pusher 70 and the insertion and engagement of the connector 32 with the second plug hole 2112 constitute a safety mechanism to prevent misoperation. Only when the connector 32 is correctly inserted into the second plug hole 2112 can the first pusher 70 be driven to move, thereby switching the state of the charging and discharging assembly 100. This design effectively avoids safety hazards caused by misoperation.

[0100] In some embodiments, the charging and discharging assembly 100 further includes a charging pile resistor and a second resistance switching unit 60, which is mounted on the main body 211. When the connector 32 is inserted into the second insertion hole 2112, the second resistance switching unit 60 is triggered by the first pushing unit 70, thereby electrically connecting the charging pile resistor, the charging / discharging gun 10, and the coupling switching plug 21. Thus, by introducing the charging pile resistor and the second resistance switching unit 60, the charging and discharging assembly 100 not only possesses the original charging and discharging function but also adds a resistance adjustment function when used as a charging pile. This ensures that the charging and discharging assembly 100 can stably and safely provide charging services for electric vehicles in charging pile mode. Through the insertion and engagement of the connector 32 with the second insertion hole 2112 and the triggering of the second resistance switching unit 60 by the first pushing unit 70, the charging and discharging assembly 100 can quickly switch from other states to charging pile mode. Users can easily connect the plug 32 into the second socket 2112 without complicated operations or adjustments, greatly improving ease of use. The introduction of the charging pile resistor helps limit the current during charging, preventing equipment damage or safety hazards caused by excessive current. Simultaneously, the precise triggering of the second resistance switching unit 60 ensures correct resistance value switching, avoiding safety issues caused by misoperation. The combined use of the second resistance switching unit 60 and the charging pile resistor gives the charging and discharging assembly 100 higher stability in charging pile mode, ensuring stable charging current output, thereby extending the lifespan of the device being charged and increasing charging power.

[0101] Reference Figure 17In some embodiments, the connector 32 is provided with a first micro-contact 321, and a first pushing part 70 is movably mounted on the main body 211 between a third position and a fourth position along the insertion direction of the connector 32. When the first pushing part 70 is in the third position, it is spaced apart from the second resistance switching part 60. When the first pushing part 70 is in the fourth position, it abuts against the second resistance switching part 60. When the connector 32 is inserted into the second plug-in hole 2112, the first micro-contact 321 drives the first pushing part 70 to switch from the third position to the fourth position. Thus, by setting the first micro-contact 321 and the first pushing part 70, an automatic driving mechanism is realized during the insertion process of the connector 32. The user only needs to insert the connector 32 into the second plug-in hole 2112, without any other manual operation, to realize the movement of the first pushing part 70 triggered by the first micro-contact 321, simplifying the operation process. The movable installation of the first pusher 70 between the third and fourth positions ensures precise switching during the insertion of the connector 32. This design avoids problems such as resistance switching failure or equipment damage due to inaccurate positioning. The cooperative design of the first micro-contact 321 and the first pusher 70 constitutes a safety mechanism to prevent misoperation. The first pusher 70 can only be driven to switch positions when the connector 32 is correctly inserted into the second socket 2112 and contacts the first micro-contact 321, thereby effectively avoiding safety hazards caused by misoperation.

[0102] It should be noted that the first micro-contact 321, as a key component driving the movement of the first pushing part 70, needs to possess high reliability and durability. Therefore, high-quality materials and advanced manufacturing processes are required to ensure its performance and lifespan. In addition to being triggered by the first micro-contact 321, the movement of the first pushing part 70 can also be triggered by a lever or magnetic attraction in other embodiments. Specifically, this application is not limited in this regard.

[0103] Reference Figure 15 and Figure 16 , Figure 15 This is the second schematic diagram of the coupling switching plug section structure when the charging and discharging assembly is in a charging state according to the exemplary embodiment of this disclosure. Figure 16 yes Figure 15The diagram shows a partially enlarged view at point F. In some embodiments, the charging / discharging assembly 100 further includes a second elastic element 80, which is elastically connected between the first pushing part 70 and the main body 211. The second elastic element 80 can move the first pushing part 70 from the fourth position to the third position. Thus, with the introduction of the second elastic element 80, the charging / discharging assembly 100 is structurally more complete, ensuring that the first pushing part 70 is stably maintained in the third position when not subjected to external force, preparing for subsequent switching to the charging pile state. The elastic force of the second elastic element 80 can counteract other external forces that may affect the first pushing part 70, such as vibration and impact, thereby maintaining the stability of the first pushing part 70 in the third position. This helps reduce problems such as charging pile resistance switching failure or equipment damage caused by external force interference. When the connector 32 is inserted into the second plug hole 2112, the first micro contact 321 drives the first pushing part 70 to switch from the third position to the fourth position. The presence of the second elastic element 80 allows the first pushing part 70 to automatically return to the third position after the connector 32 is unplugged, without requiring additional user intervention. This simplifies the operation process and improves the user experience. The second elastic element 80 holds the first pushing part 70 in the third position, effectively forming a safety mechanism to prevent accidental operation. Only when the connector 32 is correctly inserted into the second socket 2112 and contacts the first micro-contact 321 can the elasticity of the second elastic element 80 be overcome, driving the first pushing part 70 to switch positions. This design effectively avoids safety hazards caused by accidental operation.

[0104] It should be noted that the type of the second elastic element 80 can be selected as needed. For example, the second elastic element 80 may include a spring, a rubber ring, or an elastic rope, etc. Specifically, this application does not limit this. Furthermore, different types and stiffnesses of second elastic elements 80 can be selected to optimize the holding effect and operating feel of the switching unit 212, depending on the specific application scenario and requirements. Specifically, this application does not limit this. In addition, in one embodiment, the first pushing unit 70 uses the second elastic element 80 for reset. In other embodiments, it can also be reset by magnetic adsorption or gear rotation, etc. Specifically, this application does not limit this.

[0105] Reference Figure 1 and Figure 17In some embodiments, the charging pile control module 30 further includes a housing 33 with a mounting cavity and through holes 331. The control body 31 is installed in the mounting cavity. When the charging and discharging assembly 100 is in the charging pile state, the coupling switching plug 21 is connected to the inner wall of the mounting cavity through a detachable structure, and the control body 31 is plugged into the coupling switching plug 21 through a connector plug 32. The charging and discharging gun 10 is electrically connected to one end of a cable, and the other end of the cable passes through one of the through holes 331 and is electrically connected to the coupling switching plug 21. This avoids the coupling switching plug 21 and the control body 31 from being exposed, improving the safety of the charging and discharging assembly 100 when it is in the charging pile state. Exposed electrical components are easily affected by environmental factors such as dust and moisture, which may lead to short circuits or malfunctions. By setting the housing 33 to avoid the coupling switching plug 21 and the control body 31 from being exposed, the interference of these external environmental factors on the electrical components can be reduced, and the failure rate can be lowered.

[0106] It should be noted that there are various types of detachable structures. For example, in one embodiment, the detachable structure may include a matching latch protrusion 1011 and a latch slot, one of which is located in the housing 33 and the other in the coupling switching plug 21. In other embodiments, the detachable structure may include a magnetically engaging first magnetic part and a second magnetic part, one of which is located in the housing 33 and the other in the coupling switching plug 21. Specifically, this application does not limit the type of detachable structure.

[0107] Reference Figure 1 and Figure 17 In some embodiments, the housing 33 includes a housing body 332 and a cover plate 333. The housing body 332 has an opening, and the cover plate 333 is movably mounted to the housing body 332 between an open position and a closed position. In the closed position, the cover plate 333 covers the opening, so that the housing 33 and the cover plate 333 together form the mounting cavity. In the open position, the cover plate 333 opens the opening to facilitate the disassembly and assembly of the coupling switch 21.

[0108] Reference Figure 1 The shell body 332 is provided with a notch 1012, so that the user can easily plug and unplug the power strip 21 through the notch 1012.

[0109] Reference Figure 18 , Figure 18This is a schematic diagram of the charging / discharging gun, coupling switching socket, and cable assembly provided in an exemplary embodiment of this disclosure. In some embodiments, the charging / discharging assembly 100 further includes a cable assembly 90, through which the charging / discharging gun 10 and the coupling switching socket 21 are connected. The cable assembly 90 is adapted to adjust the distance between the charging / discharging gun 10 and the coupling switching socket 21. Thus, the design of the cable assembly 90 allows the distance between the charging / discharging gun 10 and the coupling switching socket 21 to be flexibly adjusted within a certain range. This design not only meets the needs of different vehicle models and different charging scenarios but also improves the convenience of charging operations. Users do not need to worry about incompatible charging interface positions or limited charging space, because the adjustable function of the cable assembly 90 ensures a suitable distance between the charging / discharging gun 10 and the coupling switching socket 21, greatly enhancing the user's charging experience. The adjustable function of the cable assembly 90 makes charging and discharging operations simpler and faster. Users only need to adjust the length of the cable 91 according to actual needs to easily complete the charging / discharging connection.

[0110] Reference Figure 18 In some embodiments, the cable assembly 90 includes a cable 91 and a reel 92. The two ends of the cable 91 are electrically connected to the charging / discharging gun 10 and the coupling switch 21, respectively. The reel 92 is used to wind the cable 91 and is adapted to adjust the length of the released cable 91. This design allows the cable 91 to be neatly wound on it, avoiding a messy appearance. This not only improves the aesthetics of the charging / discharging environment but also enhances the ease of cable 91 management. Users can easily adjust the length of the cable 91 released from the reel 92 as needed to achieve rapid charging / discharging connections. The adjustable function of the reel 92 allows the cable 91 length to be flexibly adjusted according to actual needs. This design adapts to the needs of different charging locations and distances, improving the flexibility and adaptability of charging operations. The design of the reel 92 helps reduce the risk of damage to the cable 91 caused by dragging, stepping, or other reasons. The cable 91 is neatly wound on the reel 92, avoiding wear and breakage caused by haphazard placement, thus improving the service life of the cable 91 and the reliability of the system. The adjustable function of the reel 92 allows users to easily adjust the length of the cable 91 without the need for strenuous dragging or tidying. This greatly simplifies the charging process and improves user convenience.

[0111] It should be noted that the technology for automatic winding and unwinding of cable 91 using the reel 92 is already mature, and will not be elaborated upon here. Furthermore, the cross-section of cable 91 is designed as a rectangular structure, which reduces the amount of cable material used and the space required for winding and unwinding, making it easier for the user. Of course, in other embodiments, the cross-section of cable 91 can also be circular or square; specifically, this application does not limit this to any particular designation.
