[0063] The charging and discharging device 100 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0064] Referring to Figures 1-18 As shown, the charging and discharging device 100 according to an embodiment of the present application has a discharging socket 11, a charging plug 21 and a wiring harness module 30 capable of being electrically connected with a vehicle 200. After the wiring harness module 30 is electrically connected with the vehicle 200, the charging plug 21 can be connected with an external power supply device such as a charging pile to charge the vehicle 200. Or the discharging socket 11 can be connected with an external electrical appliance such as a plug to charge the external electrical appliance by discharging the vehicle 200.

[0065] Specifically, the charging and discharging device 100 includes a fixed module 10 and a movable module 20, and the movable module 20 is provided with the charging plug 21. The discharging socket 11 is provided on at least the fixed module 10, that is, the discharging socket 11 can be provided on both the fixed module 10 and the movable module 20 (for example, as shown in Figures 1-11 As shown), or the discharging socket 11 is provided on the fixed module 10 (for example, as shown in Figures 12-18 As shown).

[0066] The wiring harness module 30 is provided on one of the fixed module 10 and the movable module 20, for example, as shown in Figures 1-11 As shown, the wiring harness module 30 is provided on the movable module 20, for example, as shown in Figures 12-18 As shown, the wiring harness module 30 is provided on the fixed module 10. In the embodiment in which the wiring harness module 30 and the charging plug 21 are always electrically connected, the charging plug 21 is provided on the movable module 20, so that even if the fixed module 10 is lost, the movable module 20 can be used alone for charging function, which is practical.

[0067] The movable module 20 is movable relative to the fixed module 10 to switch the charging and discharging device 100 between a charging mode and a discharging mode. In the charging mode, the charging plug 21 is exposed (for example, as shown in Figures 1-2 and Figure 12In the state shown, the charging plug 21 is electrically connected to the wiring harness module 30, while the discharge socket 11 is disconnected from the wiring harness module 30. The charging plug 21 is exposed to allow connection to an external power supply device. The charging plug 21 is electrically connected to the wiring harness module 30, which is capable of electrically connecting to the vehicle 200. Therefore, the charging plug 21 and the wiring harness module 30 enable electrical connection between the external power supply device and the vehicle 200 to charge the vehicle 200. The discharge socket 11 is disconnected from the wiring harness module 30, eliminating its electrical connection with the external power supply device and the vehicle 200. This de-energizes the discharge socket 11, making it less susceptible to leakage and other issues. Even if a user accidentally touches the discharge socket 11, electric shock and other issues will not occur, thereby improving the safety of the charging and discharging device 100 in charging mode.

[0068] In the discharge mode, the charging plug 21 is hidden (eg Figures 3-4 and Figure 13 (As shown), the discharge socket 11 is electrically connected to the wiring harness module 30. Hiding the charging plug 21 protects it, reducing the risk of a user accidentally touching it and causing electric shock or damage, thereby extending the lifespan of the charging plug 21. The discharge socket 11 is electrically connected to the wiring harness module 30, which in turn is electrically connected to the vehicle 200. Therefore, the discharge socket 11 and wiring harness module 30 enable electrical connection between external electrical appliances and the vehicle 200, enabling discharge of the vehicle 200 to charge the electrical appliances.

[0069] In some related technologies, vehicles are typically equipped with both charging and discharging equipment, which is both costly and time-consuming. Users need to locate both devices separately when charging or discharging their vehicles, which is both time-consuming and expensive. Furthermore, placing both devices inside the vehicle takes up more space, reducing the amount of space available for normal use.

[0070] In this application, only one set of charging and discharging equipment 100 is required to realize the charging and discharging functions of vehicle 200, which reduces the number of devices. This reduces the cost and occupies less space in the vehicle, which helps to increase the space available for normal use by the user. The user only needs to find the charging and discharging equipment 100 to charge or discharge the vehicle 200, eliminating the need to search for different devices for charging and discharging respectively, thus reducing the user's time loss and time cost.

[0071] Furthermore, when the charging and discharging device 100 is in the charging state, the discharge socket 11 is disconnected from the wiring harness module 30 and is not powered, thereby reducing the risk of electric shock from a user accidentally touching the discharge socket 11. When the charging and discharging device 100 is in the discharging state, the charging plug 21 is hidden, thereby reducing the risk of electric shock from a user accidentally touching the charging plug 21, thereby enhancing the safety of the charging and discharging device 100.

[0072] The charging and discharging device 100 according to the embodiment of the application can selectively realize the charging function and the discharging function, integrates the charging function and the discharging function, is convenient to carry, reduces the space occupation in the vehicle, is beneficial to increase the available space in the vehicle, and is safe to use because the charging and discharging device 100 is not prone to leakage or electric shock in the charging state or the discharging state.

[0073] In some embodiments of the application, as shown in Figures 5-11 and Figures 14-17 The charging and discharging device 100 further comprises a signal module 40, the signal module 40 comprises a first contact part 41 and a second contact part 42, the first contact part 41 is electrically connected with the wire harness module 30, and thus the first contact part 41 is electrified in the state that the wire harness module 30 is electrically connected with the vehicle 200.

[0074] One of the first contact part 41 and the second contact part 42 is arranged on the fixed module 10, and the other of the first contact part 41 and the second contact part 42 is arranged on the movable module 20. For example, as shown in Figures 5-11 the first contact part 41 is arranged on the movable module 20, and the second contact part 42 is arranged on the fixed module 10. For example, as shown in Figures 14-17 the first contact part 41 is arranged on the fixed module 10, and the second contact part 42 is arranged on the movable module 20.

[0075] The movable module 20 is movable relative to the fixed module 10 to selectively cooperate with the first contact part 41 and the second contact part 42 to determine the mode (charging mode or discharging mode) of the charging and discharging device 100. For example, the movable module 20 is movable relative to the fixed module 10 to make the first contact part 41 and the second contact part 42 contact or separate, so as to electrify or de-energize the second contact part 42, and then determine whether the charging and discharging device 100 is in the charging state or the discharging state.

[0076] The relative position of the movable module 20 and the fixed module 10 can be obtained according to the cooperation state of the first contact part 41 and the second contact part 42, the mode of the charging and discharging device 100 is determined, and the signal that the charging and discharging device 100 is in the charging mode or the discharging mode is transmitted to the controller of the vehicle 200, which is beneficial to realize the external charging or discharging of the whole vehicle.

[0077] In some embodiments of the application, as shown in Figures 1-7 the movable module 20 is detachably connected with the fixed module 10, and the movable module 20 has a first cooperation part 221 and a second cooperation part 222. The first cooperation part 221 and the second cooperation part 222 can be buckles, magnetic parts, threaded parts, etc.

[0078] The fixed module 10 is selectively engaged with the first engaging portion 221 or the second engaging portion 222 to switch the charging and discharging device 100 between the charging mode and the discharging mode. For example Figures 1-6 As shown, the fixed module 10 is engaged with the first engaging portion 221 to make the charging and discharging device 100 in the charging mode, and the fixed module 10 is engaged with the second engaging portion 222 to make the charging and discharging device 100 in the discharging mode. For example, the fixed module 10 is engaged with the first engaging portion 221 to make the discharging device in the charging mode, and the fixed module 10 is engaged with the second engaging portion 222 to make the charging and discharging device 100 in the charging mode.

[0079] The charging and discharging device 100 can be switched between the charging mode and the discharging mode by only adjusting the fixed module 10 to be selectively engaged with the first engaging portion 221 or the second engaging portion 222 after the movable module 20 is detached from the fixed module 10 and then reconnected to the fixed module 10, which is easy to operate and implement.

[0080] In some embodiments, as shown in Figures 1-6 and Figure 11 The fixed module 10 includes a housing 12 and a first discharging end assembly 13. The housing 12 has a socket 121 corresponding to the position of the discharging socket 11. The first discharging end assembly 13 is arranged in the housing 12 and has the discharging socket 11 and a discharging connecting terminal 131, so that when the charging and discharging device 100 is in the discharging mode, an external electrical appliance can be inserted into the housing 12 through the socket 121 to be electrically connected with the discharging socket 11.

[0081] The charging plug 21 can be electrically connected with the discharging connecting terminal 131. Specifically, when the first engaging portion 221 is engaged with the fixed module 10, the charging plug 21 is located outside the housing 12, so that the charging and discharging device 100 is in the charging mode, and the charging plug 21 is exposed to be connected with an external power supply device. When the second engaging portion 222 is engaged with the fixed module 10, the charging plug 21 is inserted into the housing 12 to be connected with the discharging connecting terminal 131, so that the charging and discharging device 100 is in the discharging mode, and the electrical connection between the movable module 20 and the fixed module 10 is achieved through the charging plug 21 and the discharging connecting terminal 131 to achieve the electrical connection between the vehicle 200 and the discharging socket 11. The connection between the charging plug 21 and the discharging connecting terminal 131 can be plug-in engagement or other connection modes.

[0082] In some embodiments, as shown in Figure 6 One side (for example, the front side of the housing 12 as shown) of the housing 12 has the socket 121, and the other side (for example, the rear side of the housing 12 as shown) of the housing 12 has the first engaging portion 221 and the second engaging portion 222. Figure 6 Figure 6 ​The rear side of the shown housing 12 has an open mouth 122, so as to load the mobile module 20 into the housing 12 through the open mouth 122, to realize the connection of the mobile module 20 and the fixed module 10.

[0083] It should be noted that the expressions about up, down, front, back, left and right in the present application are based on the directions marked in the drawings, and are not the limitation of the actual use direction of the charging and discharging module.

[0084] In some embodiments, as shown in Figures 5-6 The discharging connection terminal 131 is arranged opposite to the open mouth 122, so that after the mobile module 20 is loaded into the housing 12 from the open mouth 122, the discharging connection terminal 131 can be electrically connected with the charging plug 21 of the mobile module 20.

[0085] In some embodiments, as shown in Figures 5-6 and Figure 11 The first discharging terminal assembly 13 further has a first connecting piece 132 electrically connected with the discharging connection terminal 131. The mobile module 20 comprises a second discharging terminal assembly 23, the second discharging terminal assembly 23 has a discharging socket 11 and a second connecting piece 231 electrically connected with each other, and the first connecting piece 132 can be electrically connected with the second connecting piece 231 when the charging plug 21 and the discharging connection terminal 131 are connected.

[0086] The connection of the charging plug 21 and the discharging connection terminal 131 means that the charging plug 21 is inserted into the fixed module 10, and the discharging connection terminal 131 is electrically connected with the first connecting piece 132, so that the charging plug 21 and the first connecting piece 132 are connected. When the charging plug 21 and the discharging connection terminal 131 are connected, the first connecting piece 132 is connected with the second connecting piece 231, and the second connecting piece 231 is connected with the discharging socket 11, so that the first connecting piece 132 can be connected with the discharging socket 11, and the charging plug 21 can be electrically connected with the discharging socket 11.

[0087] Therefore, by inserting the charging plug 21 into the fixed module 10, the discharging socket 11 can be discharged through the charging plug 21, so as to charge the external electrical appliance connected with the discharging socket 11, which is convenient to operate.

[0088] For example, in some embodiments, as shown in Figures 10-11As shown, the first connecting member 132 is a plug, and the second connecting member 231 is a socket, and the first connecting member 132 is inserted into the second connecting member 231 to realize the electrical connection between the first connecting member 132 and the second connecting member 231. The discharge connecting terminal 131 is a socket, and the charging plug 21 is electrically connected with the wire harness module 30, and the charging plug 21 is inserted into the discharge connecting terminal 131 to realize the electrical connection between the charging plug 21 and the discharge connecting terminal 131. Since the discharge connecting terminal 131 is electrically connected with the first connecting member 132, and the second connecting member 231 is electrically connected with the discharge socket 11, the electrical connection between the wire harness module 30 and the discharge socket 11 can be realized.

[0089] In some embodiments, as shown in Figures 5-6 and Figure 10 As shown, the first discharge terminal assembly 13 and the second discharge terminal assembly 23 further comprise a protective sleeve 133, which is arranged outside the discharge socket 11. Before the external electrical appliance is inserted into the discharge socket 11, it passes through the protective sleeve 133 first, so that the discharge socket 11 can be separated from the outside by the protective sleeve 133, thereby reducing the risk of electric leakage.

[0090] In some embodiments of the present application, as shown in Figure 5 As shown, the movable module 20 comprises a box body 24 and a charging terminal assembly 25, and the box body 24 has a clearance 2441. At least part of the charging terminal assembly 25 is arranged in the box body 24, and the charging terminal assembly 25 comprises the wire harness module 30 and the charging plug 21, and the charging plug 21 can be inserted into the clearance 2441. The charging terminal assembly 25 is separated from the outside by the box body 24, which is beneficial to protect the charging terminal assembly 25.

In the discharging mode, the second contact part 42 extends towards the box body 24 and extends into the box body 24 through the box body 24 to contact the first contact part 41, at this time it is judged that the charging and discharging device 100 is in the discharging mode, and the signal is transmitted to the vehicle 200 controller, so that the vehicle 200 controller obtains the mode of the charging and discharging device 100 to realize external charging or discharging.

Microswitch 253 is assembled on charging end housing 254, which is then screwed onto the PCB 34. When microswitch 253 is activated, it transmits a control signal to the controller, disconnecting the power supply. This ensures that power is immediately disconnected when plugging or unplugging connectors, ensuring electrical safety for personnel.

[0131] like Figure 7As shown, the place where the operating member 251 contacts the human hand has an anti-skid structure, and its corresponding back has four convex-shaped pressing columns and two buckle-type limiting structures. The two buckles of the operating member 251 form a limiting locking structure with the two holes corresponding to the body 241, preventing the operating member 251 from being ejected from the body 241 by the elastic return member 2541. The movable member 252 is a buckle-type lock tongue, which has two guide holes matched with the guide columns of the shielding structure, a circular spring seat, and a middle operating member 251 guide circular hole. The buckle of the movable member 252 is connected with the square groove on the inner side of the shell 12 or the charging and discharging device, forming a locking state. The charging end shell 254 and the charging end shell 254 are both open groove forms, which have two guide columns of the movable member 252 inside and a carding structure controlling the first contact part 41 and the first contact part 41 outside. The charging end shell 254 and the charging end shell 254 ensure the movement characteristics of the pressing locking mechanism. In order to realize the linkage of the micro switch 253 and the movable member 252, a rectangular hole is opened at the bottom of the charging end shell 254 for the installation and guidance of the micro switch 253. When the pressing locking mechanism works, the operating member 251 is subjected to pressure from the outside, the four convex-shaped pressing columns pass through the corresponding circular holes on the body 241, and push the movable member 252 to move. At this time, the cylindrical boss on the back of the operating member 251 pushes against the contact of the micro switch 253 with the movement, and at this time the controller receives the signal and the device is powered off.

[0132] As Figure 6 and Figure 11As shown, the first discharge end assembly 13 further comprises two symmetrically arranged serpentine sockets, a Z-shaped socket located between the two serpentine sockets, and a second contact portion 42. The second contact portion 42 is connected to the Z-shaped socket via a cable. The top of the serpentine socket, near the inner plate 123, has two short pins. Together with the short pins on the upper side of the Z-shaped socket near the inner plate 123, they form a three-pin socket. The bottom of the serpentine socket, near the inner plate 123, has two sockets. Together with the sockets on the lower side of the Z-shaped socket near the inner plate 123, they form a three-socket socket. On the side of the first discharge end assembly 13 near the inner plate 123, the three-pin socket aligns with the three sockets on the inner plate 123, the three-socket socket below aligns with the three sockets on the inner plate 123, and the second contact portion 42 aligns with the circular hole on the inner plate 123. The side of the serpentine socket near the housing 12 has two sockets at the top, which together with the sockets at the top of the Z-shaped socket near the housing 12 and the two sockets in the second row of the serpentine socket form a five-socket socket. The third row of the serpentine socket near the housing 12 has two sockets. Thus, the first discharge end assembly 13 near the housing 12 is aligned with the five sockets on the housing 12 on its top and the two sockets on the housing 12 on its bottom. The housing 12 is a U-shaped groove shell structure with several small protruding clips distributed on the inner edge of the shell. These protruding clips can engage with the outer edge protrusions of the main body 241 and the cover 242. There are two square grooves on the inside of the housing 12, which are used to cooperate with the movable part 252 of the charging end to lock the charging and discharge ends during external discharge.

[0133] like Figures 1-2 As shown, when the charging and discharging device 100 is charging, the protrusion on the outer shell 12 engages with the protrusion on the outer edge of the cover 242, and the short pin of the first discharge terminal assembly 13 above the side near the inner plate 123 of the shell is inserted into the protective cover 133. Because there is no electrical connection between the discharge socket 11 and the charging plug 21, the discharge socket 11 of the entire charging and discharging device 100 is not charged at this time.

[0134] like Figures 3-4 As shown, when the raised buckle on the shell 12 cooperates with the raised buckle on the outer edge of the body 241, the three pins of the charging plug 21 are inserted into the three discharge connection terminals 131, the first contact portion 41 is connected to the second contact portion 42, and the second contact portion 42 is connected to the Z-shaped socket through a cable. The signal is transmitted to the controller through the pins of the charging plug 21, and the charging and discharging device 100 is converted to the discharge mode. At this time, the two five-socket jacks and the one two-socket jack on the charging and discharging device 100 can both discharge to the outside.

[0135] The charging and discharging device 100 has a charging plug 21 and several discharge sockets 11. When the housing 12 is matched with the cover 242 and the charging plug 21 is inserted into the discharge connection terminal 131, the first contact portion 41 and the second contact portion 42 are connected, the signal pin detects the resistance, and the controller switches the device to charging mode; when the housing 12 is matched with the body 241, the pin is connected to the internal jack of the discharge end, and the jack is connected to the second contact portion 42, and an external electrical appliance is inserted for external discharge, the signal contact detects the resistance, and the controller switches the device to discharge mode.

[0136] The charging and discharging device 100 can realize charging and discharging functions, wherein the first contact portion 41 and the second contact portion 41 can be controlled to identify the resistance of the counterpart, and the charging mode or the discharging mode is determined according to the identified resistance.

[0137] The charging and discharging device 100 has a locking mechanism. When connected to a matching external power supply device or external electrical appliance, the movable part 252 can play a locking role. When it needs to be unplugged, the locking structure triggers the micro switch 253, and the micro switch 253 transmits a control signal to switch the power supply to ensure safe use of electricity.

[0138] Since there are a temperature sensor, a temperature switch 50 and two signal pins inside the charging and discharging device 100, they need to be connected to each other. For this purpose, a PCB board 34 is designed for connecting the circuits.

[0139] The avoidance opening 2441 of the main body 241 and the socket for connecting to the discharge socket 11 are separated by wall thickness inside. There will be no safety problems with the socket during charging due to the separation of the movable module 20 and the charging module 10. During discharge, the charging plug 21 is inserted into the fixed module 10 and is not exposed, so there will be no risk of electric shock.

[0140] The fixed module 10 and the movable module 20 of the charging and discharging device 100 are integrated into one, ensuring the integrity of the device. No special discharge socket is required, and multiple three-socket and two-socket sockets are available for external discharge, which is economical, practical and highly integrated.

[0141] The following describes in detail a charging and discharging device 100 and a vehicle 200 according to a second specific embodiment of the present invention with reference to the accompanying drawings. It should be understood that the following description is merely illustrative and should not be construed as limiting the present invention.

[0142] like Figures 12-19 As shown, a charging and discharging device 100 according to a first embodiment of the present invention is used in a vehicle 200. The charging and discharging device 100 includes a fixed module 10 and a movable module 20. The movable module 20 is provided with a charging plug 21 and a wiring harness module 30 capable of electrically connecting to the vehicle 200. The fixed module 10 is provided with a discharge socket 11.

[0143] The movable module 20 is movable relative to the fixed module 10 to switch the charging and discharging device 100 between a charging mode and a discharging mode. In the charging mode, the charging plug 21 is exposed and electrically connected to the wire harness module 30, and the discharging socket 11 is disconnected from the wire harness module 30. In the discharging mode, the charging plug 21 is hidden, and the discharging socket 11 is electrically connected to the wire harness module 30.

[0144] The charging and discharging device 100 further comprises a signal module 40. The signal module 40 comprises a first contact 41 and a second contact 42. The first contact 41 is arranged on the movable module 20 and electrically connected to the wire harness module 30, and the second contact 42 is arranged on the fixed module 10. The movable module 20 is movable relative to the fixed module 10 to selectively engage the first contact 41 and the second contact 42 to determine the mode of the charging and discharging device 100.

[0145] The movable module 20 is arranged in the housing 12 of the fixed module 10 and movably engages the fixed module 10. The movable module 20 comprises a first engaging part 221 and a second engaging part 222. The first engaging part 221 is electrically connected to the charging plug 21. The movable module 20 is movable relative to the fixed module 10 to electrically connect the first engaging part 221 to the wire harness module 30 or to electrically connect the second engaging part 222 to the wire harness module 30 and the discharging socket 11.

[0146] The wire harness module 30 is arranged on the fixed module 10 and comprises a first connecting part 321 and a second connecting part 322. The first connecting part 321 and the second connecting part 322 are arranged along the moving direction of the movable module 20. At least part of the movable module 20 is arranged between the first connecting part 321 and the second connecting part 322. The movable module 20 is movable towards the first connecting part 321 to engage the first engaging part 221 with the first connecting part 321 and disengage the second engaging part 222 from the second connecting part 322. The movable module 20 is movable towards the second connecting part 322 to engage the second engaging part 222 with the second connecting part 322 and disengage the first engaging part 221 from the first connecting part 321.

[0147] The housing 12 has a partition 125. The movable module 20 comprises a movable body 26. The movable body 26 and the discharging socket 11 are arranged on opposite sides of the partition 125. The first engaging part 221 and the second engaging part 222 are arranged on the side of the movable body 26 close to the partition 125. The charging plug 21 is arranged on the side of the movable body 26 away from the partition 125.

[0148] The housing 12 has a socket and a clearance hole. The socket is in position correspondence with the discharging socket 11. The clearance hole is in position correspondence with the pin of the charging plug 21. The socket and the clearance hole are arranged on opposite sides of the housing 12.

[0149] Specifically, the shell 12 includes a lower shell 126, an intermediate shell 127 and an upper shell 128. When the press mechanism 261 on both sides of the active module 20 is pressed, the press mechanism 261 pushes the first elastic member 262 to compress, and the boss on the press mechanism 261 is out of the limiting boss of the lower shell 126. At this time, the active module 20 can slide in the space between the lower shell 126 and the intermediate shell 127. When the active module 20 slides to the topmost position, the press mechanism 261 is released, the first elastic member 262 is opened, and the press mechanism 261 is clamped into the limiting boss of the intermediate shell 127. The active module 20 is locked to the topmost position.

[0150] When the active module 20 is in the forward retracted state, the two first contact parts 41 of the active module 20 are respectively inserted into communication with the two plug-in parts 1251 of the intermediate shell 127. After the control system detects, the charging and discharging device 100 switches to the discharging state, and the plug can take power through the five holes of the upper shell 128; when the active module 20 is in the backward extended state, the first contact part 41 and the first contact part 41 are respectively disconnected with the two plug-in parts 1251 of the intermediate shell 127. At this time, after the control system detects, the charging and discharging device 100 switches to the charging state, and the three pins of the active module 20 are exposed, forming a common triangular plug to realize the charging function.

[0151] The active module 20 is placed inside the lower shell 126, and the wire harness module 30 is clamped inside through the protruding parts of the lower shell 126 and the intermediate shell 127; the discharge socket 11 is clamped into the corresponding structure of the protective sleeve 133, and then placed on the upper part of the intermediate shell 127. The upper shell 128 and the lower shell 126 are connected with the intermediate shell 127 by a buckle connection to form a whole.

[0152] The protective sleeve 133 is composed of a pin seat 1331, a second elastic member 1332 and a shielding slider 1333. When the external electrical appliance is inserted through the five holes of the upper shell 128, the external electrical appliance extrudes the inclined surface of the shielding slider 1333, so that the shielding slider 1333 translates, and then the discharge socket 11 is inserted; when the triangular plug is pulled out, the second elastic member 1332 makes the shielding slider 1333 return to the original position.

[0153] Three first matching parts 221 and two second matching parts 222 are integrally injection molded with five copper bars and the movable body 26. There are two concave holes on the movable body 26 for assembling the pressing mechanism 261 and the first elastic member 262 on both sides. There are two cross-shaped holes in the middle of the movable body 26, which match the cross-shaped guide posts on the middle shell 127 to guide the movement of the movable module 20. The first contact part 41 and the first contact part 41 are integrally injection molded on the upper surface of the movable body 26, and are connected together by a cable and a PCB board 34. The identification resistor is arranged on the PCB board 34, and then electrically connected to the first matching part 221 through screws.

[0154] There are plug-in parts 1251 and plug-in parts 1251 at the two corner parts of the middle shell 127, and the two connectors are integrally injection molded or assembled later with the middle shell 127. There are limiting blocks for protecting the sleeve 133 on the upper surface of the middle shell 127, and there are buckle structure assembly bosses on both sides.

[0155] The connected first connecting part 321 and the second connecting part 322 are communicated by two female connectors bent by a sheet metal, and a power cord 31 is welded to the connected first connecting part 321 and the second connecting part 322. The two first contact parts 41 are respectively welded to the plug-in parts 1251 of the middle shell 127.

[0156] The wire harness module 30 of the charging and discharging device 100 is composed of three power cords 31 respectively welded with three groups of first connecting parts 321 and second connecting parts 322 to form a circuit switching loop. When the charging plug 21 slides to the inside, the discharge socket 11 is communicated with the corresponding pin of the wire harness module 30, and the external discharge function can be realized. When the charging plug 21 slides to the outside, the charging plug 21 is communicated with the wire harness module 30, and the charging function can be realized.

[0157] The middle shell 127 of the charging and discharging device 100 has two plug-in parts 1251. When the charging plug 21 slides to the inside, the two first contact parts 41 are respectively inserted into the plug-in holes on the back of the corresponding plug-in parts 1251 in the middle shell 127. The connection and disconnection of the first contact part 41 and the plug-in hole realize the switching of the charging mode and the discharging mode.

[0158] There are three first matching parts 221 and two second matching parts 222 in the movable module 20 of the charging and discharging device 100, and the five copper bars are independent of each other. When the movable module 20 is retracted to the inside, the two second matching parts 222 are communicated with the wire harness module 30 and the discharge socket 11, realizing the discharge communication, and the first matching part 221 of the movable module 20 is not electrified, ensuring the safety of electricity use.

[0159] Other configurations and operations of the charging and discharging device 100 and the vehicle 200 according to the embodiments of the present application are known to those skilled in the art, and thus will not be described in detail herein.
