[0041] like Figure 3 As shown, when it is necessary to charge the first electronic device that is compatible with the first interface 110, the second interface 120 is inserted into the second socket 220, so that the power supply body 200 can discharge to the outside through the cable 100, that is, the first interface 110 can charge the first electronic device.

[0042] like Figure 4As shown, when it is necessary to charge the second electronic device that is compatible with the second interface 120, the first interface 110 is inserted into the first socket 210, so that the power supply body 200 can discharge to the outside through the cable 100, that is, the second interface 120 can charge the second electronic device.

[0043] When the power supply unit 200 needs to be charged, the second interface 120 is inserted into the second socket 220, and the first interface 110 is connected to an external adapter, so that the cable 100 and the adapter can work together to charge the power supply unit 200.

[0044] The charging and discharging device 10 in the above embodiments has bidirectional charging and discharging functions. In actual use, it can complete charging or discharging without repeatedly switching the connection positions between the power supply body 200 and the cable 100, simplifying the charging and discharging process of the charging and discharging device 10. Simultaneously, the charging and discharging device 10 can reduce the number of insertions and removals between the first interface 110 and the first socket 210, and between the second interface 120 and the second socket 220, preventing the power supply body 200 from malfunctioning due to loosening or damage to the first socket 210 or the second socket 220, thereby extending the service life of the charging and discharging device 10.

[0045] Both the first interface 110 and the second interface 120 can be any interface structure in the prior art. The type of the first interface 110 is different from that of the second interface 120, so as to be able to charge electronic devices with different charging socket types.

[0046] Optionally, one of the first interface 110 and the second interface 120 is set to a Lightning interface, and the other is set to a Type-C interface.

[0049] like Figure 3As shown, when it is needed to charge the Android electronic device, the Lightning interface is inserted into the Lightning interface socket, so that the power body 200 can discharge externally through the wire 100, that is, the Type-C interface can be electrically connected with the installed electronic device to charge the installed electronic device.

[0050] As shown, Figure 4 As shown, when it is needed to charge the Apple electronic device, the Type-C interface is inserted into the Type-C interface socket, so that the power body 200 can discharge externally through the wire 100, that is, the Lightning interface can be electrically connected with the Apple electronic device to charge the Apple electronic device.

[0051] When it is needed to charge the power body 200, the Lightning interface is inserted into the Lightning interface socket, and the Type-C interface is externally connected with the adapter, so that the wire 100 can cooperate with the adapter to charge the power body 200.

[0052] In one embodiment, the number of the wire 100 is two, one of the two wires 100 is electrically connected with the first socket 210 through the first interface 110, and the other is electrically connected with the second socket 220 through the second interface 120. In this way, the power body 200 can be electrically connected with the first electronic device and the second electronic device through the two wires 100, so as to be able to charge the electronic devices of two different interface types at the same time. In addition, the power body 200 can be electrically connected with the adapter through one of the two wires 100, and be electrically connected with the first electronic device or the second electronic device through the other of the two wires 100, so as to be able to realize discharging while charging.

[0053] As shown, Figure 1 , Figure 5 and Figure 6As shown, in one embodiment, the power supply body 200 comprises a shell 230, a circuit board 240 and a power supply element 250, the circuit board 240 and the power supply element 250 are both mounted in the shell 230, the circuit board 240 is electrically connected with the power supply element 250, and the outer wall of the shell 230 is provided with a first recess 231 and a second recess 232.

When the first interface 110 is inserted into the first socket 210, the first end 130 is interference-fitted with the first recess 231; when the second interface 120 is inserted into the second socket 220, the second end 140 is interference-fitted with the second recess 232.

[0054] Wherein, the socket hole on the first socket 210 is oppositely arranged with the first mounting hole 233 can be that, along the axis direction of the first mounting hole 233, the projection area of the socket hole on the first socket 210 and the projection area of the first mounting hole 233 completely or highly overlap, which ensures that the first interface 110 can pass through the first mounting hole 233 and be inserted into the first socket 210. In the embodiment, the socket hole on the first socket 210 is oppositely arranged with the first mounting hole 233.

[0055] Wherein, the socket hole on the second socket 220 is oppositely arranged with the second mounting hole 234 can be that, along the axis direction of the second mounting hole 234, the projection area of the socket hole on the second socket 220 and the projection area of the second mounting hole 234 completely or highly overlap, which ensures that the second interface 120 can pass through the second mounting hole 234 and be inserted into the second socket 220. In the embodiment, the socket hole on the second socket 220 is oppositely arranged with the second mounting hole 234.

[0056] As shown in Figure 1 , Figure 7 and Figure 8 , further, the two inner side walls of the first recess 231 are both provided with a first protrusion 235, when the first interface 110 is inserted into the first socket 210, the two first protrusions 235 correspondingly abut and fit with the two outer side walls of the first end 130. In this way, the two first protrusions 235 can clamp and fix the first end 130, so as to ensure that the first interface 110 can be stably and reliably inserted into the first socket 210, and improve the reliability of the charging and discharging equipment 10.

[0057] As shown in Figure 6 , Figure 7 andFigure 8 As shown in FIG. 13, optionally, in the direction (as shown by arrow D) of inserting the first end 130 into the first recess 231, the first protrusion 235 comprises mutually connected lead-in portions 2351 and abutting portions 2352, the interval between the two lead-in portions 2351 gradually decreases, the interval between the two lead-in portions 2351 near the end of the first mounting hole 233 and the interval between the two abutting portions 2352 are the same, and the two abutting portions 2352 are used for abutting cooperation with the first end 130. In this way, the lead-in portions 2351 can play a guiding role, ensuring that the first end 130 can be smoothly inserted into the first recess 231, and improving the convenience of using the charging and discharging device 10. Figure 7

[0058] As shown in FIG. 13, optionally, the second recess 232 is provided with second protrusions on the opposite inner side walls, and when the second interface 120 is inserted into the second socket 220, the two second protrusions abut and cooperate with the corresponding two outer side walls of the second end 140. In this way, the two second protrusions can clamp and fix the second end 140, so as to ensure that the second interface 120 can be stably and reliably inserted into the second socket 220, and improve the reliability of the charging and discharging device 10. Figure 1 Figure 8

[0059] Specifically, in the embodiment, the structure of the second protrusion is the same as or similar to that of the first protrusion 235, which will not be described in detail here.

[0060] As shown in FIG. 13, specifically, in the embodiment, the shell 230 comprises a first shell 237 and a second shell 238, the first shell 237 is detachably connected with the second shell 238 by clamping or screwing, and surrounds to form a mounting space. The power supply 250, the circuit board 240, the second socket 220 and the first socket 210 are all located in the mounting space. The first recess 231 and the second recess 232 are both located on the same side of the first shell 237. Figure 1 As shown in FIG. 13, in one embodiment, the first mounting hole 233 and the first recess 231 cooperate to form a first closed space 260, the second mounting hole 234 and the second recess 232 cooperate to form a second closed space 270, and the charging and discharging device 10 further comprises a closing member 300. The closing member 300 is used to close the first closed space 260 when the first interface 110 moves out of the first closed space 260, and / or the closing member 300 is used to close the second closed space 270 when the second interface 120 moves out of the second closed space 270.

[0061] Figure 8 Figure 9

[0062] ​​​​​​The closure 300 can be configured as a rubber stopper, silicone stopper, or other sealing structure. The number of closures 300 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, there are two closures 300, which are respectively configured as a first closure and a second closure.

[0063] The first closure is used to close the first closed space 260 when the first interface 110 is removed from the first closed space 260. Thus, when the first interface 110 is electrically connected to the first electronic device or adapter, the first closure is inserted into the first closed space 260 to prevent external dust and other foreign objects from passing through the first closed space 260 and entering the housing 230, thereby improving the reliability of the charging and discharging device 10.

[0064] The second closure is used to close the second closed space 270 when the second interface 120 is removed from the second closed space 270. Thus, when the second interface 120 is electrically connected to the second electronic device or adapter, the second closure is inserted into the second closed space 270 to prevent external dust and other foreign objects from passing through the second closed space 270 and entering the housing 230, thereby improving the reliability of the charging and discharging device 10.

[0065] In other embodiments, the number of closure members 300 can be one. One closure member 300 can close the first closed space 260 when the first interface 110 moves out of the first closed space 260, and can also close the second closed space 270 when the second interface 120 moves out of the second closed space 270.

[0066] like Figure 1 and Figure 8 As shown, optionally, the inner wall of the first groove 231 is provided with an opening 236. The opening 236 extends from the side of the housing 230 where the first groove 231 is provided toward the side of the housing 230 away from the first groove 231, and the side of the opening 236 away from the first groove 231 extends to the outer wall of the housing 230. In this way, when it is necessary to move the first end 130 or the closure 300 out of the first groove 231, the opening 236 can serve as a clearance space, thereby increasing the contact area between the user and the first end 130 or the closure 300 to facilitate the application of force and improve the convenience of using the charging and discharging device 10.

[0067] like Figure 10As shown, in particular to the present embodiment, the first closure member includes a first closure portion 310, a second closure portion 320 and a third closure portion 330. The relative positions between the first closure portion 310, the second closure portion 320 and the third closure portion 330 are the same as the relative positions between the first recess 231, the first mounting hole 233 and the opening 236. When the first closure member closes the first closed space 260, the outer contour shape of the first closure portion 310 is adapted to the inner contour shape of the first recess 231, and the outer wall of the first closure portion 310 is smoothly connected with the outer wall of the outer shell 230; the outer contour shape of the second closure portion 320 is adapted to the inner contour shape of the first mounting hole 233; the outer contour shape of the third closure portion 330 is adapted to the inner contour shape of the opening 236, and the outer wall of the third closure portion 330 is smoothly connected with the outer wall of the outer shell 230.

[0068] In particular to the present embodiment, the second closure member includes a fourth closure portion and a fifth closure portion. The relative positions between the fourth closure portion and the fifth closure portion are the same as the relative positions between the second recess 232 and the second mounting hole 234. When the second closure member closes the second closed space 270, the outer contour shape of the fourth closure portion is adapted to the inner contour shape of the second recess 232, and the outer wall of the fourth closure portion is smoothly connected with the outer wall of the outer shell 230; the outer contour shape of the fifth closure portion is adapted to the inner contour shape of the second mounting hole 234.

[0069] As shown in FIG. 1, in one embodiment, the first recess 231 and the second recess 232 are arranged on the same side of the outer shell 230. In this way, the wire 100 can be accommodated on one side of the power supply body 200, improving the convenience of carrying the charging and discharging device 10. Figure 1 In other embodiments, the first recess 231 and the second recess 232 can also be arranged on different sides of the outer shell 230, respectively. For example, the first recess 231 and the second recess 232 are arranged on opposite sides of the outer shell 230, or the first recess 231 and the second recess 232 are arranged on adjacent sides of the outer shell 230.

[0070] As shown in FIG. 1, in one embodiment, the first recess 231 and the second recess 232 are arranged on the same side of the outer shell 230. In this way, the wire 100 can be accommodated on one side of the power supply body 200, improving the convenience of carrying the charging and discharging device 10.

[0071] Figure 1 and Figure 8 As shown in FIG. 1, in one embodiment, the first recess 231 and the second recess 232 are arranged on the same side of the outer shell 230. In this way, the wire 100 can be accommodated on one side of the power supply body 200, improving the convenience of carrying the charging and discharging device 10.

[0072] ​Specifically to the embodiment, the first recess 231 has a first bottom wall and three first side walls, which are located at three sides of the first bottom wall respectively, so that three of the four sides of the first recess 231 are closed, and the other side is open. The second recess 232 has a second bottom wall and four second side walls, which are located at four sides of the second bottom wall respectively, so as to correspondingly close the four sides of the second recess 232.

[0073] As Figure 1 shown, optionally, the power supply body 200 further comprises a wireless charging assembly 280, which is located in the shell 230 and is electrically connected with the circuit board 240. The wireless charging assembly 280 is used for charging electronic devices with wireless charging function. In this way, the power supply body 200 has the wireless charging function, thereby improving the practicability of the charging and discharging device 10.

[0074] Among them, the wireless charging assembly 280 can be set as any wireless charging structure in the prior art.
