[0046] When using the energy supply device 10 of this embodiment, when the charging seat 111 is connected to an external power source, the power supply structure 200 can be powered by the external power source. When the external power source is removed, the power supply structure 200 can be powered by the built-in first battery 220, and output through the first contact 210 to power the external power receiving device. In the energy supply device 10 of this embodiment, by using the charging seat 111 and the first battery 220, wired power supply and wireless power supply can be realized, and the convenience is improved; by using the first contact 210 to connect to the power receiving device, the heating condition of the device can be improved compared with wireless charging, and the structure is simple and the use effect is good.

[0047] In one embodiment, the connecting member 300 includes a magnetic member, and the magnetic member is used for magnetically connecting with the power receiving device.

[0048] With this arrangement, when the external power receiving device is connected to the energy supply device 10, the magnetic attraction member can attract the power receiving device through magnetic force and fix the power receiving device to the energy supply device 10. At this time, the power receiving device realizes electrical conduction by contacting with the first contact 210, thereby supplying power and charging the power receiving device. In other embodiments, the connector 300 may also be a pin, and the power receiving device is provided with a hole to facilitate the pin to be plugged in and out of it; the connector 300 may also be a buckle, which is snap-fitted with the power receiving device through the buckle. By providing a detachable connection between the connector 300 and the power receiving device in the energy supply device 10, the disassembly and assembly of the two can be facilitated, the convenience of use can be improved, and the fixing is firm.

[0049] Specifically, the energy supply device 10 further includes a charging cable 400 , which is connected to the housing 100 and electrically connected to the control module 230 . The charging cable 400 is used to supply energy to the outside or charge the first battery 220 .

[0050] It can be understood that the charging cable 400 can be a separate structure from the shell 100, which is convenient for removing the charging cable 400 to improve the portability of the energy supply device 10, or it can be an integrated connection structure. With this arrangement, the user does not need to carry an additional charging cable when using the energy supply device 10, and the convenience of use is also improved.

[0051] See also Figure 2 As shown, in one embodiment, the charging cable 400 includes a connecting cable 410 and a charging connector 420, one end of the connecting cable 410 is connected to the shell 100 and is electrically connected to the control module 230, and the charging connector 420 is connected to the other end of the connecting cable 410; the shell 100 includes a shell body 110 and a fixing ring 120, the fixing ring 120 is connected to the shell body 110, the connecting cable 410 is passed through the fixing ring 120 from one end of the fixing ring 120, and the charging connector 420 is located at the other end of the fixing ring 120.

[0052] In this embodiment, the charging connector 420 is connected to the shell 100 through the fixing ring 120. When the charging connector 420 contacts one side of the fixing ring 120, the connecting line 410 is in a ring structure and can be used as a hand strap to facilitate the user to carry the energy supply device 10. When the charging cable 400 is needed, the charging connector 420 can be pulled out from the direction away from the fixing ring 120 so that the charging cable 400 extends to the outside of the shell 100, which is convenient for powering the power receiving device or charging the energy supply device 10.

[0053] Furthermore, the shell body 110 is provided with a receiving groove 112 , the fixing ring 120 is disposed in the receiving groove 112 , and the charging connector 420 is suspended in the receiving groove 112 .

[0054] With this arrangement, when the charging connector 420 contacts the fixing ring 120, the fixing ring 120 can be accommodated in the receiving groove 112, so that the combined structure of the shell 100 and the charging cable 400 is compact. When the charging connector 420 is completely immersed in the receiving groove 112, the outer surface of the shell 100 can be flat, and the charging connector 420 can also be protected to prevent it from being damaged by external bumps.

[0055] It should be noted that in this embodiment, the control module can be, but is not limited to, various PLCs (Programmable Logic Controller, full name Programmable Logic Control), STM32 (STM32 microcontroller, a 32-bit microcontroller with ARM Cortex-M core), single-chip microcomputer, FPGA (Field Programmable Gate Array, full name Field Programmable Gate Array), ARM (ARM processor, full name Advanced RISC Machi ne), etc., which are arranged inside the device to directly control the device and obtain the operating status of the device. Of course, in some embodiments, the power supply structure 200 also includes a control button 240 electrically connected to the control module 230, and by touching the control button 240, a control instruction can be input to the control module 230, such as switching the operating status of the energy supply device 10.

[0056] The utility model also provides an electronic device 1, which includes the energy supply device 10 and the wireless charging device 30 in any one of the above embodiments; the power receiving device 20 includes a shell 202, a second contact 201 and a circuit module, the circuit module is arranged inside the shell 202 and is electrically connected to the second contact 201, the second contact 201 is connected to the shell 202 and at least partially protrudes outward from the shell 202, the second contact 201 is used to contact and lead with the first contact 210, and the power receiving device 20 is fixedly connected to the shell 100 through the connecting member 300.

[0057] It can be understood that in the electronic device 1 of the present embodiment, by setting the energy supply device 10 in any of the above embodiments, when the electronic device 1 is in use, when the charging seat 111 is connected to the external power supply, the power supply structure 200 can be powered by the external power supply, and when the external power supply is removed, the power supply structure 200 can be powered by the built-in first battery 220, and output through the first contact 210 to power the power receiving device 20. In the energy supply device 10 of the present embodiment, by using the charging seat 111 and the first battery 220 to cooperate, wired power supply and wireless power supply can be realized, and the convenience is improved; by using the first contact 210 to connect with the second contact 201 of the power receiving device 20, the heating condition of the device can be improved compared with wireless charging, the structure is simple, and the use effect is good. In a preferred embodiment, the first contact 210 and the second contact 201 can be POGOPIN, so that the two can maintain abutment under the action of elasticity, thereby reducing the internal resistance when the two are connected and improving the power supply stability.

[0058] In one embodiment, the power receiving device 20 further includes a magnetic member 203 , and the connecting member 300 is a magnetic attraction member. The power receiving device 20 and the energy supply device 10 are magnetically connected and fixed to the magnetic attraction member via the magnetic member 203 .

[0059] According to this arrangement, when the power receiving device 20 is connected to the energy supply device 10, the first contact 210 is first aligned with the second contact 201. As the power receiving device 20 and the energy supply device 10 gradually come into contact, the connecting member 300 in the housing 100 can generate a magnetic effect with the magnetic member 203 in the power receiving device 20, thereby adsorbing and fixing the power receiving device 20 and the energy supply device 10. When separation is required, the two can be separated by moving them away from each other and overcoming the magnetic attraction, which is convenient for assembly and disassembly.

[0060] Further, see Figure 2 and Figure 4 As shown, the housing 202 is provided with a positioning groove 2021, which is arranged around the second contact 201, and the housing 100 is provided with a positioning portion 130, which is arranged around the first contact 210; when the power receiving device 20 is connected to the power supply device 10, the positioning portion 130 is inserted into the positioning groove 2021.

[0061] In this embodiment, by respectively providing the positioning portion 130 and the positioning groove 2021 on the housing 100 and the shell 202, when the energy supply device 10 is connected to the power receiving device 20, the positioning portion 130 and the positioning groove 2021 can be plugged in and matched for positioning, so that the installation convenience and connection accuracy are improved. At the same time, since the positioning portion 130 and the positioning groove 2021 are arranged around the first contact 210 and the second contact 201, the connection stability between the first contact 210 and the second contact 201 can be improved. Of course, in some embodiments, the positioning groove 2021 and the positioning portion 130 can also be arranged in an exchanged position, that is, the positioning portion is provided on the shell 202, and the positioning groove is provided on the housing 100, thereby realizing the positioning function between the two.

[0063] Thus, the shell 100 and the outer shell 202 have different concave-convex structures, namely, the connecting groove 113 and the connecting boss 2022. At this time, when the shell 100 and the outer shell 202 are connected, the connecting groove 113 and the connecting boss 2022 are used to prevent foolish positioning. Compared with the contact using a plane, it can not only increase the contact area between the two, but also avoid accidental contact between the first contact 210 and the second contact 201 when the shell 100 and the outer shell 202 are installed in reverse, and at the same time facilitate the alignment of the two. In this process, with the help of the magnetic cooperation of the magnetic part 203 and the magnetic suction part, the assembly convenience and accuracy of the energy supply device 10 and the power receiving device 20 can be effectively improved. Of course, the connecting boss 2022 and the connecting groove 113 can also be interchanged, that is, the outer shell 202 is provided with a connecting groove, and the shell 100 is provided with a connecting boss, thereby also realizing the positioning function between the two.
