Therefore, this application is not limited to the specific embodiments disclosed below.

This application discloses a charging and discharging device, which includes some or all of the technical features of the following embodiments; that is, the charging and discharging device includes some or all of the following structures. In one embodiment of this application, a charging and discharging device includes a wire and a power supply body: the wire has a first end and a second end disposed opposite to each other, the first end is provided with a first interface, and the second end is provided with a second interface, the type of the first interface and the type of the second interface are different; the power supply body is provided with a first socket and a second socket, the first socket is adapted to the first interface, and the second socket is adapted to the second interface. The above-mentioned charging and discharging device has bidirectional charging and discharging function, and in actual use, it is not necessary to repeatedly switch the connection position between the power supply body and the wire to complete the charging or discharging work, which simplifies the charging and discharging process of the charging and discharging device. At the same time, the charging and discharging device in this application can also reduce the number of plugging and unplugging between the first interface and the first socket, and between the second interface and the second socket, which can avoid the situation where the power supply body cannot be used normally due to the loosening or damage of the first socket or the second socket, thereby extending the service life of the charging and discharging device. The charging and discharging device will be described in detail below with reference to Figures 1 to 10. illustrate.

As shown in Figure 1, in one embodiment, a charging and discharging device 10 is provided, including a cable 100 and a power supply body 200. The cable 100 has a first end 130 and a second end 140 disposed opposite to each other. The first end 130 is provided with a first interface 110, and the second end 140 is provided with a second interface 120. The type of the first interface 110 and the type of the second interface 120 are different. The power supply body 200 is provided with a first socket 210 and a second socket 220. The first socket 210 is adapted to the first interface 110, and the second socket 220 is adapted to the second interface 120.

As shown in Figure 2, when the power supply body 200 does not need to charge or discharge, the first interface 110 is inserted into the first socket 210 and the second interface 120 is inserted into the second socket 220, so that the cable 100 is neatly stored on the power supply body 200, and it is also convenient for the user to hold the charging and discharging device 10.

As shown in Figure 3, 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.

As shown in Figure 4, 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.

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.

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.

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.

In some embodiments, one of the first interface 110 and the second interface 120 is configured as a Lightning interface and the other is configured as a Type-C interface.

In this specific embodiment, the first interface 110 is configured as a Type-C interface. The second interface 120 is configured as a Lightning interface. The first socket 210 is configured as a Type-C interface socket, and the second socket 220 is configured as a Lightning interface socket. The first electronic device corresponds to an Android electronic device, and the second electronic device corresponds to an Apple electronic device.

As shown in Figure 2, when the power supply unit 200 does not need to charge or discharge, the Type-C interface is inserted into the Type-C interface socket and the Lightning interface is inserted into the Lightning interface socket, so that the cable 100 is neatly stored on the power supply unit 200, and it is also convenient for the user to hold the charging and discharging device 10.

As shown in Figure 3, when it is necessary to charge an Android electronic device, the Lightning interface is inserted into the Lightning interface socket, so that the power supply body 200 can discharge to the outside through the cable 100. That is, the Type-C interface can be electrically connected to the installed electronic device to charge the installed electronic device.

As shown in Figure 4, when it is necessary to charge an Apple electronic device, the Type-C interface is inserted into the Type-C interface socket, so that the power supply body 200 can discharge to the outside through the cable 100. That is, the Lightning interface can be electrically connected to the Apple electronic device to charge the Apple electronic device.

When the power supply unit 200 needs to be charged, insert the Lightning interface into the Lightning interface socket and connect the Type-C interface to the external adapter so that the cable 100 and the adapter can be used to charge the power supply unit 200.

In one embodiment, there are two cables 100. One cable 100 is electrically connected to the first socket 210 via the first interface 110, and the other cable 100 is electrically connected to the second socket 220 via the second interface 120. Thus, the power supply unit 200 can be electrically connected to both the first and second electronic devices via the two cables 100, enabling simultaneous charging of two electronic devices with different interface types. Furthermore, the power supply unit 200 can be electrically connected to the adapter via one of the two cables 100, and to either the first or second electronic device via the other cable, enabling simultaneous charging and discharging.

As shown in Figures 1, 5, and 6, in one embodiment, the power supply body 200 includes a housing 230, a circuit board 240, and a power supply component 250. Both the circuit board 240 and the power supply component 250 are installed inside the housing 230, and the circuit board 240 and the power supply component 250 are electrically connected. The outer wall of the housing 230 is provided with a first groove 231 and a second groove 232. The bottom wall of the first groove 231 is provided with a first mounting hole 233 communicating with the inner cavity of the housing 230. A first socket 210 is fixed to the circuit board 240 and electrically connected to it, with the socket on the first socket 210 facing the first mounting hole 233. The bottom wall of the second groove 232 is provided with a second mounting hole 234 communicating with the inner cavity of the housing 230. A second socket 220 is fixed to the circuit board 240 and electrically connected to it, with the socket on the second socket 220 facing the second mounting hole 234. When the first interface 110 is inserted into the first socket 210, the first end 130 is in interference fit with the first groove 231; when the second interface 120 is inserted into the second socket 220, the second end 140 is in interference fit with the second groove 232.

In this embodiment, the socket on the first socket 210 and the first mounting hole 233 are positioned opposite each other such that, along the axial direction of the first mounting hole 233, the projected areas of the socket on the first socket 210 and the projected areas of the first mounting hole 233 completely overlap or highly overlap, ensuring that the first interface 110 can pass through the first mounting hole 233 and be inserted into the first socket 210. Specifically, in this embodiment, the socket on the first socket 210 and the first mounting hole 233 are directly opposite each other.

The socket on the second socket 220 and the second mounting hole 234 can be positioned opposite each other, with the sockets positioned along the second mounting hole 234. Along the axial direction, the projection area of the socket on the second socket 220 and the projection area of the second mounting hole 234 completely overlap or highly overlap, ensuring that the second interface 120 can pass through the second mounting hole 234 and be inserted into the second socket 220. Specifically, in this embodiment, the socket on the second socket 220 is directly opposite the second mounting hole 234.

As shown in Figures 1, 7, and 8, furthermore, each of the two opposing inner sidewalls of the first groove 231 is provided with a first protrusion 235. When the first interface 110 is inserted into the first socket 210, the two first protrusions 235 abut against the two opposing outer sidewalls of the first end 130. In this way, the two first protrusions 235 can cooperate to 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, thereby improving the reliability of the charging and discharging device 10.

As shown in Figures 6, 7, and 8, in some embodiments, along the direction in which the first end 130 is inserted into the first groove 231 (as shown by D in Figure 7), the first protrusion 235 includes an interconnected guide portion 2351 and an abutment portion 2352. The distance between the two guide portions 2351 gradually decreases, and the distance between the ends of the two guide portions 2351 closest to the first mounting hole 233 is the same as the distance between the two abutment portions 2352. Both abutment portions 2352 are used to engage with the first end 130. In this way, the guide portion 2351 can play a guiding role, ensuring that the first end 130 can be smoothly inserted into the first groove 231, improving the ease of use of the charging and discharging device 10.

As shown in Figures 1 and 8, in some embodiments, the two inner sidewalls of the second groove 232 are provided with second protrusions. When the second interface 120 is inserted into the second socket 220, the two second protrusions abut against the two outer sidewalls of the second end 140. In this way, the two second protrusions can cooperate to 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, thereby improving the reliability of the charging and discharging device 10.

In this specific embodiment, the structure of the second protrusion is the same as or similar to that of the first protrusion 235, and will not be described in detail here.

As shown in Figure 1, in this specific embodiment, the outer casing 230 includes a first casing 237 and a second casing 238. The first casing 237 is detachably connected to the second casing 238 by means of snap-fit or screw connection, and forms an installation space. The power supply component 250, circuit board 240, second socket 220, and first socket 210 are all located within the installation space. The first groove 231 and the second groove 232 are both located on the same side of the first casing 237.

As shown in Figures 8 and 9, in one embodiment, the first mounting hole 233 and the first groove 231 cooperate to form a first enclosed space 260, and the second mounting hole 234 and the second groove 232 cooperate to form a second enclosed space 270. The charging and discharging device 10 also includes a sealing member 300. The sealing member 300 is used to close the first enclosed space 260 when the first interface 110 is removed from the first enclosed space 260, and/or, the sealing member 300 is used to close the second enclosed space 270 when the second interface 120 is removed from the second enclosed space 270.

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.

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.

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.

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.

As shown in Figures 1 and 8, in some embodiments, 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.

As shown in Figure 10, in this specific embodiment, the first sealing member includes a first sealing portion 310, a second sealing portion 320, and a third sealing portion 330. The relative positions of the first sealing portion 310, the second sealing portion 320, and the third sealing portion 330 are the same as the relative positions of the first groove 231, the first mounting hole 233, and the opening 236. When the first sealing member closes the first sealing space 260, the outer contour shape of the first sealing portion 310 matches the inner contour shape of the first groove 231, and the outer wall of the first sealing portion 310 smoothly transitions with the outer wall of the outer shell 230; the outer contour shape of the second sealing portion 320 matches the inner contour shape of the first mounting hole 233; the outer contour shape of the third sealing portion 330 matches the inner contour shape of the opening 236, and the outer wall of the third sealing portion 330 smoothly transitions with the outer wall of the outer shell 230.

Specifically, in this embodiment, the second closure includes a fourth closure portion and a fifth closure portion. The relative positions between the fourth and fifth closure portions are the same as the relative positions between the second groove 232 and the second mounting hole 234. When the second closure closes the second enclosed space 270, the outer contour shape of the fourth closure portion matches the inner contour shape of the second groove 232, and the outer wall of the fourth closure portion smoothly transitions with the outer wall of the outer shell 230; the outer contour shape of the fifth closure portion matches the inner contour shape of the second mounting hole 234.

As shown in Figure 1, in one embodiment, the first groove 231 and the second groove 232 are spaced apart and disposed on the same side of the housing 230. Thus, the cable 100 can be stored on one side of the power supply body 200, improving the portability of the charging and discharging device 10.

In other embodiments, the first groove 231 and the second groove 232 may also be disposed on different sides of the outer casing 230. For example, the first groove 231 and the second groove 232 may be disposed on opposite sides of the outer casing 230, or the first groove 231 and the second groove 232 may be disposed on adjacent sides of the outer casing 230.

As shown in Figures 1 and 8, in some embodiments, the side of the first groove 231 away from the second groove 232 extends to the outer wall of the housing 230. Thus, the first groove 231 and the second groove 232 can be positioned on the side of the outer wall of the housing 230 with a smaller area, improving the practicality of the charging and discharging device 10.

Specifically, in this embodiment, the first groove 231 has a first bottom wall and three first side walls, which are respectively located on three sides of the first bottom wall, so that three of the four sides of the first groove 231 are closed and the other side is open. The second groove 232 has a second bottom wall and four second side walls, which are respectively located on the four sides of the second bottom wall, so as to correspondingly close the four sides of the second groove 232.

As shown in Figure 1, in some embodiments, the power supply unit 200 further includes a wireless charging component 280. The wireless charging component 280 is located inside the housing 230 and electrically connected to the circuit board 240. The wireless charging component 280 is used to charge electronic devices with wireless charging functionality. Thus, the power supply unit 200 has wireless charging functionality, improving the practicality of the charging and discharging device 10.

The wireless charging component 280 can be configured as any of the existing wireless charging structures.
