[0022] Please also refer to Figures 1 to 3 , Figure 1 1 is a schematic structural diagram of a first embodiment of a charging device 100 according to the present invention; Figure 2 1 is a schematic structural diagram of the charging device 100 of the present invention in an open cover state; Figure 3 yes Figure 1 Schematic diagram of the charging device 100 in use. The present invention provides a charging device 100, comprising a lower housing 20, an upper housing 30, a switch mechanism 40, and a mainboard 60 disposed within the lower housing 20; the switch mechanism 40 comprises a first magnetic member 44 disposed on the upper housing 30, a second magnetic member 46 disposed on the lower housing 20, and a control unit 48 disposed within the lower housing 20 or the upper housing 30, the control unit 48 being electrically connected to the mainboard 60; the controller 48 is configured to control the magnetic relationship between the first magnetic member 44 and the second magnetic member 46, wherein the magnetic relationship includes attraction, no magnetic force, or repulsion. Specifically, the controller 48 controls the magnetic relationship between the first magnetic part 44 and the second magnetic part 46 to be attractive, so that the upper shell 30 covers the lower shell 20, that is, the upper shell 30 and the lower shell 20 are in a closed state; the controller 48 controls the magnetic relationship between the first magnetic part 44 and the second magnetic part 46 to be non-magnetic or repulsive, that is, the upper shell 30 and the lower shell 20 are in an open state, so as to release the fixed connection between the upper shell 30 and the lower shell 20, thereby facilitating the opening of the upper shell 30.

[0023] The first magnetic member 44 is a soft magnetic body, which is an iron block, and the second magnetic member 46 is an electromagnet. The second magnetic member 46 is electrically connected to the control unit 48. The control unit 48 is used to place the second magnetic member 46 in a first energized state when the upper shell 30 and the lower shell 20 are in a closed state, so that the second magnetic member 46 and the first magnetic member 44 are attracted to each other. The first energized state in this embodiment refers to the control unit 48 controlling the power circuit of the second magnetic member 46 to remain energized. Specifically, the electromagnet maintains a energized state to generate a magnetic attraction effect on the soft magnetic body, so that the upper shell 30 is covered on the lower shell 20 through the magnetic attraction between the first magnetic member 44 and the second magnetic member 46.

[0024] In this embodiment, the charging device 100 is wirelessly paired with a user terminal 300, such as by Bluetooth. When the user terminal 300 approaches the charging device 100, it sends a cover-opening signal to the control unit 48. Upon receiving the cover-opening signal, the control unit 48 controls the second magnetic member 46 to be in a second energized state, deenergizing the circuit of the second magnetic member 46. This results in a zero-magnetic relationship between the first magnetic member 44 and the second magnetic member 46, i.e., the attractive force between the first magnetic member 44 and the second magnetic member 46 disappears, thereby facilitating opening of the upper housing 30. The second energized state refers to the deenergized state of the circuit of the second magnetic member 46 controlled by the control unit 48.

[0025] The charging device 100 can be an earphone charging device or a battery charging device, etc. In this embodiment, the charging device 100 is an earphone charging device, which is used to charge wireless earphones; the user terminal 300 is a mobile phone, and the user terminal 300 is successfully paired with the charging device 100 through Bluetooth technology. When the user terminal 300 is close to the charging device 100, it can send an open cover signal to the control unit 48, or when the charging device 100 searches for the user terminal 300, it can send an open cover signal to the control unit 48; the control unit 48 receives the open cover signal and controls the magnetic relationship between the first magnetic part 44 and the second magnetic part 46, and the control unit 48 is also used to send connection information to the charged device in the charging device 100 according to the open cover signal, and the connection information is used to indicate that the charged device is connected to the user terminal 300; the connection information can also be used to indicate that the connection between the charged device and the user terminal 300 is disconnected.

[0026] Specifically, when the charged device in the charging device 100 has been charged and needs to be taken out, the user terminal 300 is close to the charging device 100, and the controller 48 receives the cover-opening signal to control the second magnetic part 46 to be placed in the second power-on state, that is, the power-on circuit of the second magnetic part 46 is powered off, so that the magnetic relationship between the first magnetic part 44 and the second magnetic part 46 is non-magnetic, so as to facilitate opening the upper shell 30; at the same time, the controller 48 sends connection information to the charged device in the charging device 100 according to the cover-opening signal, so that the charged device and the user terminal 300 are successfully connected. When the charged device needs to be charged, the user terminal 300 is close to the charging device 100, and the controller 48 receives the cover-opening signal to control the second magnetic part 46 to be placed in the second power-on state, that is, the power circuit of the second magnetic part 46 is de-energized, so that the magnetic relationship between the first magnetic part 44 and the second magnetic part 46 is non-magnetic, and the charged device is placed in the charging device 100 after the upper shell 30 is opened; the controller 48 also sends connection information to the charged device according to the cover-opening signal, so that the connection between the charged device and the user terminal 300 is disconnected.

[0027] Furthermore, the control unit 48 includes a communication unit, which is in communication with the user terminal 300 and is configured to receive the cover-opening signal sent by the user terminal 300 or send the cover-opening signal to the control unit 48 when the user terminal 300 is found.

[0028] In this embodiment, the lower shell 20 is provided with a receiving cavity 22 corresponding to the upper shell 30, and the receiving cavity 22 is used to accommodate the charged device; when the second magnetic member 46 maintains the first power-on state, that is, the power-on circuit of the second magnetic member 46 is energized, the magnetic relationship between the first magnetic member 44 and the second magnetic member 46 is attraction, so that the upper shell 30 covers the opening of the empty cavity 20 of the lower shell 20; when the user terminal 300 is close to the charging device 100, the communication unit is communicated with the user terminal 300, and the communication unit receives the cover-opening signal sent by the user terminal 300 or sends the cover-opening signal to the control unit 48 when searching for the user terminal 300. The control unit 48 receives the cover-opening signal to control the second magnetic member 46 to be placed in the second power-on state, that is, the power-on circuit of the second magnetic member 46 is de-energized, and the magnetic relationship between the second magnetic member 46 and the first magnetic member 44 is non-magnetic, thereby facilitating the opening of the upper shell 30.

[0029] When the control unit 48 of the switch mechanism 40 of the charging device 100 of the present invention controls the second magnetic member 46 to be placed in the first power-on state, the magnetic relationship between the second magnetic member 46 and the first magnetic member 44 is attraction; when the user terminal 300 is close to the charging device 100, the control unit 48 receives the cover-opening signal sent by the user terminal 300 or sends the cover-opening signal to the control unit 48 when searching for the user terminal 300, so as to control the second magnetic member 46 to be placed in the second power-on state, demagnetize the second magnetic member 46, and make the magnetic relationship between the first magnetic member 44 and the second magnetic member 46 non-magnetic, so as to facilitate the opening of the upper shell 30, and facilitate the user to place the charged device such as wireless headphones in the accommodating cavity 22 of the lower shell 20, or to take out the charged device that has been charged from the accommodating cavity 22; no manual operation is required, it is easy to use, and the user experience is improved.

[0030] The lower shell 20 includes a bottom plate 21, a front plate 23, a back plate 24, and two opposite side plates 25. The accommodating cavity 22 is surrounded by the front plate 23, the back plate 24 and the two side plates 25, and is located at one end away from the bottom plate 21. The top of the accommodating cavity 22 passes through the top surface of the lower shell 20 to form an opening, and the upper shell 30 is used to cover the opening. The lower shell 20 is provided with a charging terminal electrically connected to the mainboard in the accommodating cavity 22. When the charged device is accommodated in the accommodating cavity 22, the charging interface of the charged device is electrically connected to the charging terminal. In this embodiment, the second magnetic member 46 is located at the top of the front plate 23 of the lower shell 20.

[0031] Preferably, a positioning mechanism may be further provided in the accommodating cavity 22 of the lower shell 20 , and the positioning mechanism is used to position the charged device accommodated in the accommodating cavity 22 .

[0032] One end of the upper shell 30 is hinged to the lower shell 20. The first magnetic member 44 is located at one end of the upper shell 30 away from the hinge between the upper shell 30 and the lower shell 20. The second magnetic member 46 is located on the lower shell 20 away from the hinge, and the second magnetic member 46 corresponds to the first magnetic member 44. Specifically, the upper shell 30 includes a front end 301 and a rear end 303. The first magnetic member 44 is provided at the front end 301 of the upper shell 30. The rear end 303 of the upper shell 30 is hinged to the top end of the back plate 24 of the lower shell 20. In this embodiment, the rear end 303 of the upper shell 30 is rotatably connected to the back plate 24 of the lower shell 20 via a rotating shaft 305.

[0033] Preferably, a first elastic member 27 is provided at the hinged joint between the upper shell 30 and the lower shell 20. The first elastic member 27 is used to apply an elastic force that drives the upper shell 30 and the lower shell 20 to rotate relative to each other and open the cover. The elastic force can drive the upper shell 30 to rotate relative to the lower shell 20 to automatically open the cover. When the second magnetic member 46 is in a first energized state, that is, the power circuit of the second magnetic member 46 is energized, the magnetic force between the second magnetic member 46 and the first magnetic member 44 is greater than the force exerted by the first elastic member 27 to drive the upper shell 30 to rotate away from the lower shell 20, thereby allowing the upper shell 30 to stably cover the lower shell 20. When the second magnetic member 46 is in a second energized state, that is, the power circuit of the second magnetic member 46 is de-energized, the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is no magnetic force, and the first elastic member 27 elastically resets, driving the upper shell 30 to rotate relative to the lower shell 20 and automatically opening the cover.

[0034] In this embodiment, the first elastic member 27 is a torsion spring comprising a first elastic rod 272 and a second elastic rod 274. The first elastic rod 272 and the second elastic rod 274 are connected to the upper housing 30 and the lower housing 20, respectively. When the upper housing 30 is opened relative to the lower housing 20, the torsion spring is in its original state, whereby the torsion spring has not undergone any elastic deformation. When the upper housing 30 is covered relative to the lower housing 20 and the second magnetic member 46 is in the first energized state, the torsion spring is in an elastically deformed state, but the elastic torsion force of the torsion spring is less than the magnetic attraction between the first magnetic member 44 and the second magnetic member 46.

[0035] like Figure 3As shown, when the charging device 100 has completed charging the wireless headset accommodated in the accommodating cavity 22 and the user needs to take out the wireless headset, at this time, the second magnetic member 46 is placed in the first power-on state, that is, the power circuit of the second magnetic member 46 is energized; the user only needs to hold the user terminal 300 close to the charging device 100, and the communication unit of the control unit 48 is connected to the user terminal 300 for communication, and the communication unit receives the cover-opening signal sent by the user terminal 300 or sends the cover-opening signal to the control unit 48 when searching for the user terminal 300, and the control unit 48 receives the cover-opening signal and controls the second magnetic member 46 to be placed in the second power-on state, that is, the second magnetic member 46 is powered on. The power circuit of the magnetic member 46 is de-energized, so that the magnetic relationship between the first magnetic member 44 and the second magnetic member is non-magnetic, and the first elastic member 27 elastically resets and drives the upper shell 30 to rotate toward the opening away from the accommodating cavity 22, so as to complete the automatic opening of the upper shell 30, making it convenient for the user to take out the wireless headset from the accommodating cavity 22 without manual operation to open the cover, which is easy to use and improves the user experience; at the same time, the control unit 48 is also used to send connection information to the charged device in the charging device 100 according to the cover opening signal, and the connection information is used to instruct the charged device to connect to the user terminal 300, that is, to enable the charged device to communicate with the user terminal 300.

[0036] When it is necessary to charge the charged device such as a wireless headset, at this time, the second magnetic member 46 is placed in the first power-on state, that is, the power circuit of the second magnetic member 46 is energized, and the user only needs to hold the user terminal 300 and the wireless headset close to the charging device 100, and the communication unit of the control unit 48 is connected to the user terminal 300 for communication, and the communication unit receives the cover-opening signal sent by the user terminal 300 or sends the cover-opening signal to the control unit 48 when searching for the user terminal 300, and the control unit 48 receives the cover-opening signal and controls the second magnetic member 46 to be placed in the second power-on state, that is, the second magnetic member 46 is powered on. The power circuit of the magnetic member 46 is de-energized, so that the magnetic relationship between the first magnetic member 44 and the second magnetic member is non-magnetic, and the first elastic member 27 elastically resets to drive the upper shell 30 to rotate toward the opening away from the accommodating cavity 22, so as to complete the automatic opening of the upper shell 30, making it convenient for the user to place the wireless headset in the accommodating cavity 22; at the same time, the control unit 48 is also used to send connection information to the charged device according to the opening signal, and the connection information is used to indicate that the connection between the charged device and the user terminal 300 is disconnected, that is, the communication connection between the charged device and the user terminal 300 is disconnected.

[0037] In other embodiments, the first magnetic member 44 is a hard magnet, i.e., the first magnetic member 44 is a permanent magnet, and the second magnetic member 46 is an electromagnet. When the second magnetic member 46 is in a first energized state, i.e., the electromagnet's power circuit is de-energized, the first magnetic member 44 and the second magnetic member 46 are attracted to each other, i.e., the hard magnet and the electromagnet's core are magnetically attracted to each other. The control unit 48 receives the cover opening signal and controls the second magnetic member 46 to be in a second energized state, i.e., the electromagnet's power circuit is energized, so that the magnetic relationship between the second magnetic member 46 and the first magnetic member 44 is repulsive, i.e., the hard magnet and the electromagnet repel each other. Specifically, when the upper shell 30 covers the lower shell 20 and the power circuit of the electromagnet is de-energized, the hard magnet and the iron core of the electromagnet are magnetically attracted to each other; when the control unit 48 receives the cover opening signal, it controls the electromagnet to be placed in the second power-on state, that is, the power circuit of the electromagnet is energized, so that the first magnetic member 44 and the second magnetic member 46 are magnetically repelled, and the elastic reset of the first elastic member 27 and / or the magnetic repulsive force drive the upper shell 30 to rotate toward the opening away from the accommodating chamber 22 to complete the automatic opening of the upper shell 30. In this embodiment, when the upper shell 30 covers the lower shell 20, the power circuit of the second magnetic member 46 is in the de-energized state, that is, the second magnetic member 46 does not need to consume power; the charging device 100 only controls the power circuit of the second magnetic member 46 to be energized during the process of opening the upper shell 30, which consumes less power and is energy-saving and environmentally friendly.

[0038] In other embodiments, the first magnetic member 44 and the second magnetic member 46 are both electromagnets, and the controller 48 controls the second magnetic member 46 to be placed in a first energized state, wherein the first energized state is that the energized circuits of the second magnetic member 46 are all de-energized, and the energized circuits of the first magnetic member 44 are energized, so that the magnetic relationship between the first magnetic member 44 and the second magnetic member 46 is attractive, so that the upper shell 30 covers the lower shell 20; when the controller 48 receives the cover opening signal, it controls the second magnetic member 46 to be placed in a second energized state, wherein the second energized state is that the energized circuits of the second magnetic member 46 are all energized, so that the magnetic relationship between the first magnetic member 44 and the second magnetic member 46 is repulsive. Specifically, when the upper shell 30 covers the lower shell 20 and one of the power circuits of the two electromagnets is energized and the other is de-energized, specifically, the power circuit of the second magnetic part 46 is de-energized and the power circuit of the first magnetic part 44 is energized, the first magnetic part 44 and the second magnetic part 46 both generate magnetic force and attract each other; when the control part 48 receives the cover opening signal, it controls the power circuit of the second magnetic part 46 to be energized so that the magnetic force relationship between the first magnetic part 44 and the second magnetic part 46 is repulsive, and the elastic reset of the first elastic part 27 and / or the magnetic repulsive force drive the upper shell 30 to rotate toward the opening away from the accommodating cavity 22 to complete the automatic opening of the upper shell 30.

[0039] In other embodiments, the first magnetic member 44 is a self-holding electromagnet, the second magnetic member 46 is an electromagnet, and the controller 48 controls the second magnetic member 46 to be placed in a first energized state, wherein the first energized state is when the power circuit of the electromagnet is de-energized and the power circuit of the self-holding electromagnet is de-energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is attraction, so that the upper shell 30 covers the lower shell 20; when the controller 48 receives the cover opening signal, it controls the second magnetic member 46 to be placed in a second energized state, wherein the second energized state is when the power circuit of the electromagnet is energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is no magnetic force or repulsion. Specifically, when the upper shell 30 covers the lower shell 20, and the self-holding electromagnet and the power circuit of the electromagnet are both de-energized, the iron core of the electromagnet is magnetically attracted to the self-holding electromagnet. When the control unit 48 receives the cover-opening signal, it controls the power-on circuit of the electromagnet to be energized, so that the magnetic relationship between the self-holding electromagnet and the electromagnet is repulsive, and the elastic reset of the first elastic member 27 and / or the magnetic repulsive force drive the upper shell 30 to rotate toward the opening away from the accommodating chamber 22, so as to complete the automatic cover opening of the upper shell 30; or when the control unit 48 receives the cover-opening signal, it controls the power-on circuit of the electromagnet to be de-energized and the power-on circuit of the self-holding electromagnet to be energized, so that the magnetic relationship between the self-holding electromagnet and the electromagnet is non-magnetic, and the first elastic member 27 elastically resets and drives the upper shell 30 to rotate toward the opening away from the accommodating chamber 22, so as to complete the automatic cover opening of the upper shell 30. In this embodiment, when the upper shell 30 covers the lower shell 20, the power circuits of the first magnetic part 44 and the second magnetic part 46 are both in a power-off state, that is, the first magnetic part 44 and the second magnetic part do not need to consume electricity; the charging device only controls the power circuits of the first magnetic part 44 and / or the second magnetic part 16 to be energized when the upper shell 30 is opened, which results in less power consumption and energy saving and environmental protection.

[0040] In other embodiments, the first magnetic member 44 is a soft magnet, and the second magnetic member 46 is a self-holding electromagnet. The controller 48 controls the second magnetic member 46 to be in a first energized state, where the power circuit of the self-holding electromagnet is de-energized, so that the magnetic force between the first magnetic member 44 and the second magnetic member 46 is attracted, thereby causing the upper housing 30 to cover the lower housing 20. When the controller 48 receives a cover-opening signal, it controls the second magnetic member 46 to be in a second energized state, where the power circuit of the self-holding electromagnet is energized, so that the magnetic force between the first magnetic member 44 and the second magnetic member 46 is non-magnetic. Specifically, when the upper shell 30 covers the lower shell 20 and the power circuit of the self-holding electromagnet is in the power-off state, the soft magnetic body and the self-holding electromagnet are magnetically attracted to each other; when the control unit 48 receives the cover opening signal, it controls the power circuit of the self-holding electromagnet to be energized so that there is no magnetic force between the self-holding electromagnet and the soft magnetic body, and the first elastic member 27 elastically resets and drives the upper shell 30 to rotate toward the opening away from the accommodating chamber 22, thereby completing the automatic opening of the upper shell 30. In this embodiment, when the upper shell 30 covers the lower shell 20, the power circuit of the second magnetic member 46 is in the power-off state, that is, the second magnetic member 46 does not need to consume electricity; the charging device only controls the power circuit of the second magnetic member 46 to be energized during the process of opening the upper shell 30, which consumes less electricity and is energy-saving and environmentally friendly.

[0041] In other embodiments, the first magnetic member 44 is a hard magnet, that is, the first magnetic member 44 is a permanent magnet, and the second magnetic member 46 is a self-holding electromagnet; the control unit 48 controls the second magnetic member 46 to be in a first energized state, that is, the power circuit of the self-holding electromagnet is de-energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is attraction, that is, the hard magnet and the self-holding electromagnet are magnetically attracted. The control unit 48 receives the cover opening signal and controls the second magnetic member 46 to be in a second energized state, that is, the power circuit of the self-holding electromagnet is energized, so that the magnetic force relationship between the second magnetic member 46 and the first magnetic member 44 is non-magnetic or repulsive. Specifically, when the upper shell 30 covers the lower shell 20 and the power circuit of the self-holding electromagnet is de-energized, the hard magnet and the self-holding electromagnet are magnetically attracted to each other; when the control unit 48 receives the cover opening signal, it controls the self-holding electromagnet to be placed in the second power-on state, that is, the power circuit of the self-holding electromagnet is energized, so that there is no magnetic force or repulsion between the first magnetic member 44 and the second magnetic member 46, and the elastic reset and / or magnetic repulsion force of the first elastic member 27 drives the upper shell 30 to rotate toward the opening away from the accommodating chamber 22 to complete the automatic opening of the upper shell 30. In this embodiment, when the upper shell 30 covers the lower shell 20, the power circuit of the second magnetic member 46 is in the de-energized state, that is, the second magnetic member 46 does not need to consume power; the charging device 100 controls the power circuit of the second magnetic member 46 to be energized only when the upper shell 30 is opened, which reduces power consumption and is energy-saving and environmentally friendly.

[0042] In other embodiments, the first magnetic member 44 is an electromagnet, and the second magnetic member 46 is a self-holding electromagnet. The controller 48 controls the second magnetic member 46 to be in a first energized state, where the power circuit of the self-holding electromagnet is de-energized, and the power circuit of the electromagnet is also de-energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is attracted, so that the upper shell 30 covers the lower shell 20. When the controller 48 receives the cover opening signal, it controls the second magnetic member 46 to be in a second energized state, where the power circuit of the self-holding electromagnet is energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is non-magnetic. Specifically, when the upper shell 30 covers the lower shell 20, and the self-holding electromagnet and the power circuit of the electromagnet are both in the power-off state, the iron core of the electromagnet and the self-holding electromagnet are magnetically attracted; when the control unit 48 receives the cover opening signal, it controls the power circuit of the self-holding electromagnet to be energized so that there is no magnetic force between the self-holding electromagnet and the electromagnet; or the control unit 48 controls the power circuit of the electromagnet to be energized, and the power circuit of the holding electromagnet remains power-off, so that the self-holding electromagnet and the electromagnet repel each other, and the elastic reset of the first elastic member 27 and / or the magnetic repulsion force drive the upper shell 30 to rotate toward the opening away from the accommodating cavity 22 to complete the automatic opening of the upper shell 30.

[0043] In other embodiments, both the first magnetic member 44 and the second magnetic member 46 are self-holding electromagnets, and the controller 48 controls the second magnetic member 46 to be in a first energized state, where the power circuit of the self-holding electromagnet is de-energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is attraction, thereby causing the upper housing 30 to cover the lower housing 20. When the controller 48 receives a cover-opening signal, it controls the second magnetic member 46 to be in a second energized state, where the power circuits of the two self-holding electromagnets are energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is non-magnetic or repulsive. Specifically, when the upper shell 30 covers the lower shell 20 and the power circuits of the two self-holding electromagnets are both de-energized, the two self-holding electromagnets are magnetically attracted to each other; when the control unit 48 receives the cover opening signal, it controls the power circuits of the two self-holding electromagnets to be energized, so that the magnetic relationship between the two self-holding electromagnets is non-magnetic or repulsive, and the elastic reset and / or magnetic repulsion of the first elastic member 27 drives the upper shell 30 to rotate toward the opening away from the accommodating chamber 22 to complete the automatic opening of the upper shell 30. In this embodiment, when the upper shell 30 covers the lower shell 20, the power circuits of the first magnetic member 44 and the second magnetic member 46 are both in the de-energized state, that is, the first magnetic member 44 and the second magnetic member 46 do not need to consume electricity; the charging device only controls the power circuits of the first magnetic member 44 and the second magnetic member 46 to be energized during the opening process of the upper shell 30, which consumes less power and is energy-saving and environmentally friendly.

[0044] In other embodiments, a damper is further provided at the hinge between the upper shell 30 and the lower shell 20 , and the damper can slowly open the upper shell 30 relative to the lower shell 20 to prevent damage to the upper shell 30 .

[0045] See also Figure 4 , Figure 4Figure 2 is a schematic diagram of the structure of a second embodiment of a charging device 100a according to the present invention. The structure of the charging device 100a according to the second embodiment of the present invention is similar to that of the charging device 100 according to the first embodiment, except that the first elastic member 27a in the second embodiment is different from the first elastic member 27 in the first embodiment. Specifically, an elastic sheet is provided between the upper housing 30 and the lower housing 20. The elastic sheet is used to elastically push against the upper housing 30 to automatically open the upper housing 30. The elastic sheet includes a positioning portion 275 fixed to the lower housing 20 and adjacent to the upper housing 30, and a pushing portion 276 that elastically pushes against the upper housing 30. When the upper housing 30 is in an open position relative to the lower housing 20, the elastic sheet is in its original position. When the upper housing 30 is in a covered position relative to the lower housing 20, the elastic sheet is elastically deformed, but the elastic pushing force of the elastic sheet is less than the magnetic force between the first magnetic member 44 and the second magnetic member 46. When the user holds the user terminal 300 close to the charging device 100a, the user terminal 300 will transmit an opening signal to the charging device 100a, and the control unit 48 receives the opening signal and turns off the power circuit of the second magnetic member 46. After the power circuit of the second magnetic member 46 is powered off, there is no magnetic force between the first magnetic member 44 and the second magnetic member 46, and the elastic sheet elastically resets and pushes the upper shell 30 to rotate toward the opening away from the accommodating cavity 22, so as to complete the automatic opening of the upper shell 30, which is easy to use and improves the user experience.

[0046] In other embodiments, the positioning portion 275 of the first elastic member 27 a may also be fixed to the upper housing 30 adjacent to the lower housing 20 , and the pushing portion 276 elastically contacts the top of the lower housing 20 .

[0047] In other embodiments, the upper shell 30 and the lower shell 20 may also be provided with a compression spring, which is used to elastically push the upper shell 30 to automatically open the cover. Specifically, when the upper shell 30 is in a covering state relative to the lower shell 20, the compression spring is elastically deformed, but the elastic resistance of the compression spring is less than the magnetic force between the first magnetic member 44 and the second magnetic member 46. When the power circuit of the second magnetic member 46 is de-energized, there is no magnetic force between the first magnetic member 44 and the second magnetic member 46, and the elastic return force of the compression spring pushes the upper shell 30 relative to the lower shell 20 to automatically open the cover.

[0048] In other embodiments, a tension spring is provided between the back of the lower shell 20 and the back of the upper shell 30, and the tension spring is used to elastically pull the upper shell 30 to rotate relative to the lower shell 20 to open the cover; specifically, when the upper shell 30 is in a covering state relative to the lower shell 20, the tension spring is in an elastically deformed state, but the elastic tension of the tension spring is less than the magnetic force between the first magnetic part 44 and the second magnetic part 46; when the second magnetic part 46 is powered off, there is no magnetic force between the first magnetic part 44 and the second magnetic part 46, and the elastic reset force of the tension spring pulls the upper shell 30 to rotate relative to the lower shell 20 to open the cover.

[0049] Please also refer to Figure 5 and Figure 6 , Figure 5 is a structural diagram of a third embodiment of a charging device 100b of the present invention; Figure 6 yes Figure 5 Schematic diagram of the structure of the charging device 100b in the open state. The structure of the charging device 100b of the third embodiment of the present invention is similar to that of the charging device 100 of the first embodiment, except that: in the third embodiment, the upper housing 30a is slidably mounted on the lower housing 20, the first magnetic member 44 is a hard magnet, and the second magnetic member is an electromagnet. Specifically, the first magnetic member 44 is mounted on one side of the upper housing 30a, and the second magnetic member 46 is mounted on the top of the lower housing 20 adjacent to the first magnetic member 44. The first magnetic member 44 corresponds to the second magnetic member 46 in the sliding direction of the upper housing 30a. When the upper shell 30a completely covers the lower shell 20, the control unit 48 controls the second magnetic part 46 to be placed in a first power-on state, and the first power-on state refers to that the power-on circuit of the electromagnet is in a power-off state, so that the hard magnet is adsorbed on the iron core of the electromagnet; when the control unit 48 controls the second magnetic part 46 to be placed in a second power-on state, that is, the power-on circuit of the electromagnet is energized, the magnetic relationship between the first magnetic part 44 and the second magnetic part 46 is repulsive, so as to drive the upper shell 30a to automatically slide relative to the lower shell 20 and away from the second magnetic part 46 until the opening of the accommodating chamber 22 is completely exposed, so that the user can conveniently place the charged device into the accommodating chamber 22 or take the charged device out of the accommodating chamber 22 without manually opening the cover, which is easy to use and improves the user experience.

[0050] In this embodiment, when the upper shell 30a covers the lower shell 20, the power circuit of the second magnetic part 46 is in a power-off state, that is, the second magnetic part 46 does not need to consume electricity; the charging device 100b only controls the power circuit of the second magnetic part 46 to be energized when the upper shell 30a is opened, which consumes less electricity and is energy-saving and environmentally friendly.

[0051] The upper shell 30a is slidably connected to the lower shell 20 via a slide groove at the opening of the lower shell 20, or the upper shell 30a can also be slidably connected to the lower shell 20 through the cooperation of the slide groove and the slide rail. Specifically, the inner circumferential surface of the opening of the lower shell 20 is provided with a slide groove 28 along the sliding direction of the upper shell 30a, and the outer circumferential surface of the upper shell 30a is provided with a slide rail 35 that slidably cooperates with the slide groove 28. A stopper 282 is provided at the end of the slide groove 28 on the side of the lower shell 20 away from the second magnetic member 46. The stopper 282 is used to prevent the upper shell 30 from separating from the lower shell 20.

At the same time, the control unit 48 is also used to send connection information to the charged device in the charging device 100b according to the cover opening signal, and the connection information is used to indicate that the charged device is connected to the user terminal 300, so that the charged device is communicated with the user terminal 300.

[0053] When it is necessary to charge the charged device such as a wireless headset, at this time, the second magnetic member 46 is placed in the first power-on state, that is, the power circuit of the second magnetic member 46 is powered off, and the hard magnet and the iron core of the electromagnet are magnetically attracted; the user only needs to hold the user terminal 300 and the wireless headset close to the charging device 100b, and the communication unit of the control unit 48 is connected to the user terminal 300 for communication, and the communication unit receives the cover-opening signal sent by the user terminal 300 or sends the cover-opening signal to the control unit 48 when searching for the user terminal 300, and the control unit 48 receives the cover-opening signal and controls the second magnetic member 46 to be placed in the second power-on state, that is The power circuit of the second magnetic part 46 is energized, so that the magnetic relationship between the first magnetic part 44 and the second magnetic part is repulsive, and the magnetic repulsive force drives the upper shell 30a to slide toward the side away from the second magnetic part 46 until the opening of the accommodating cavity 22 is completely exposed, thereby completing the automatic opening of the upper shell 30a, making it convenient for the user to place the wireless headset in the accommodating cavity 22; at the same time, the control unit 48 is also used to send connection information to the charged device according to the opening signal, and the connection information can also be used to indicate that the connection between the charged device and the user terminal 300 is disconnected, that is, the charged device is connected to the user terminal 300 for communication.

[0054] In other embodiments, both the first magnetic member 44 and the second magnetic member 46 are electromagnets, and the controller 48 controls the second magnetic member 46 to be in a first energized state, where the first energized state is when the power circuit of the second magnetic member 46 is de-energized and the power circuit of the first magnetic member 44 is energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is attraction, thereby causing the upper housing 30a to cover the lower housing 20. In other embodiments, the controller 48 can also control the power circuit of the first magnetic member 44 to be de-energized and the power circuit of the second magnetic member 46 to be energized. When the controller 48 receives a cover-opening signal, it controls the second magnetic member 46 to be in a second energized state, where both the power circuits of the second magnetic member 46 are energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is repulsion. Specifically, when the upper shell 30a covers the lower shell 20, and the power circuit of one electromagnet is energized and the power circuit of the other electromagnet is de-energized, a magnetic force is generated between the first magnetic part 44 and the second magnetic part 46, and they attract each other; when the control unit 48 receives the opening signal, it controls the power circuits of the two electromagnets to be energized, so that the magnetic force relationship between the first magnetic part 44 and the second magnetic part 46 is repulsive, and the magnetic repulsive force drives the upper shell 30a to slide toward the side away from the second magnetic part 46 until the opening of the accommodating cavity 22 is completely exposed, thereby completing the automatic opening of the upper shell 30a.

[0055] In other embodiments, the first magnetic member 44 is a self-holding electromagnet, the second magnetic member 46 is an electromagnet, and the controller 48 controls the second magnetic member 46 to be placed in a first energized state, wherein the first energized state is when the power circuit of the electromagnet is de-energized and the power circuit of the self-holding electromagnet is de-energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is attraction, so that the upper shell 30a covers the lower shell 20; when the controller 48 receives the cover opening signal, it controls the second magnetic member 46 to be placed in a second energized state, wherein the power circuit of the electromagnet is energized, so that the magnetic force relationship between the first magnetic member 44 and the second magnetic member 46 is repulsion. Specifically, when the upper shell 30a covers the lower shell 20 and the self-holding electromagnet and the power circuit of the electromagnet are both de-energized, the iron core of the electromagnet is magnetically attracted to the self-holding electromagnet. When the control unit 48 receives the cover opening signal, it controls the power circuits of the electromagnets to be energized, so that the magnetic force relationship between the self-holding electromagnet and the electromagnet is repulsive. The magnetic repulsive force drives the upper shell 30a to slide toward the side away from the second magnetic member 46 until the opening of the accommodating cavity 22 is completely exposed, thereby completing the automatic opening of the upper shell 30a. In this embodiment, when the upper shell 30a covers the lower shell 20, the power circuits of the first magnetic member 44 and the second magnetic member 46 are both in a power-off state, that is, the first magnetic member 44 and the second magnetic member do not need to consume power. The charging device only controls the power circuit of the second magnetic member 16 to be energized during the opening process of the upper shell 30, which reduces power consumption and is energy-saving and environmentally friendly.

[0056] In other embodiments, the inner circumference of the lower shell 20 is provided with a slide rail along the sliding direction of the upper shell 30a, and the outer circumference of the upper shell 30a is provided with a slide groove that slides with the slide rail.

[0057] Please also refer to Figure 7 and Figure 8 , Figure 7 1 is a schematic structural diagram of a fourth embodiment of a charging device 100c according to the present invention; Figure 8 yes Figure 7Schematic diagram of the structure of the charging device 100c in the open state. The structure of the charging device 100c of the fourth embodiment of the present invention is similar to that of the charging device 100b of the third embodiment, except that: in the fourth embodiment, a second elastic member 37 is provided between the upper housing 30a and the lower housing 20. The second elastic member 37 is used to apply an elastic force that drives the upper housing 30a and the lower housing 20 to slide relative to each other and open the cover, causing the upper housing 30a to slide relative to the lower housing 20 to automatically open the cover. In this embodiment, the second elastic member 37 is a compression spring, which is connected between the upper shell 30a and the lower shell 20; when the upper shell 30a completely covers the lower shell 20, the second magnetic member 46 is an electromagnet, and the power circuit of the electromagnet is in a power-off state. The first magnetic member 44 is a hard magnet, and the magnetic relationship between the first magnetic member 44 and the second magnetic member 46 is attraction, that is, the hard magnet is adsorbed on the iron core of the electromagnet, and the compression spring is compressed and deformed between the upper shell 30a and the lower shell 20. The compression spring has an elastic force on the upper shell 30a to slide away from the second magnetic member 46, and the elastic thrust is less than the adsorption magnetic force between the second magnetic member 46 and the first magnetic member 44, so that the upper shell 30a remains in a closed state. When the control unit 48 receives the cover-opening signal, the controller 48 controls the second magnetic member 46 to be in the second energized state, i.e., the electromagnet's energized circuit is energized, so that the magnetic force between the second magnetic member 46 and the first magnetic member 44 is repulsive. The magnetic repulsion and / or the thrust generated by the elastic return of the second elastic member 37 together push the upper housing 30a to slide away from the second magnetic member 46 until the upper housing 30a is blocked by the stopper 282, completely exposing the opening of the accommodating chamber 22. The addition of the second elastic member 37 in this embodiment can make the upper housing 30a slide faster.

[0058] In this embodiment, the upper shell 30a is provided with a push-up plate 38. When the upper shell 30a completely covers the accommodating cavity 22 of the lower shell 20, one end of the second elastic member 37 is positioned on the lower shell 20, and the other opposite end of the second elastic member 37 elastically pushes against the push-up plate 38; when the power circuit of the second magnetic member 46 is de-energized, the elastic push force of the second elastic member 37 on the upper shell 30a is smaller than the adsorption magnetic force between the second magnetic member 46 and the first magnetic member 44.

[0059] The first magnetic part 44 is a soft magnet, which is an iron block, and the second magnetic part 46 is an electromagnet; the controller 48 controls the second magnetic part 46 to be placed in a first power-on state, in which the power-on circuits of the electromagnets are all powered on, so that the magnetic force relationship between the first magnetic part 44 and the second magnetic part 46 is attraction, so that the upper shell 30a covers the lower shell 20; when the controller 48 receives the cover opening signal, it controls the second magnetic part 46 to be placed in a second power-on state, in which the power-on circuits of the electromagnets are all powered off, so that the magnetic force relationship between the first magnetic part 44 and the second magnetic part 46 is no magnetism. Specifically, when the upper shell 30a covers the lower shell 20 and the power circuits of the electromagnets are energized, the first magnetic part 44 and the second magnetic part 46 both generate magnetic force and attract each other; when the control unit 48 receives the cover opening signal, it controls the power circuits of the electromagnets to be de-energized so that there is no magnetic force between the first magnetic part 44 and the second magnetic part 46, and the second elastic part 37 elastically resets and drives the upper shell 30a to slide toward the side away from the second magnetic part 46 to complete the automatic opening of the upper shell 30a.

[0060] In other embodiments, the second elastic member 37 is a tension spring, which is connected between the upper shell 30a and the lower shell 20. Specifically, one end of the tension spring is connected to the upper shell 30a, and the other end of the tension spring is connected to the lower shell 20. When the upper shell 30a completely covers the lower shell 20, the power circuit of the second magnetic member 46 is in a power-off state and is magnetically attracted to the first magnetic member 44. The tension spring is stretched and deformed between the upper shell 30a and the lower shell 20, and the tension spring has an effect on the upper shell 30a to move away from the second magnetic member. 46 slides with an elastic pulling force, and the elastic pulling force is smaller than the adsorption magnetic force between the second magnetic part 46 and the first magnetic part 44, so that the upper shell 30a remains in a closed state; when the control part 48 receives the cover opening signal, it controls the energy circuit of the second magnetic part 46 to be energized to generate a magnetic force that repel each other with the first magnetic part 44, and the magnetic force and / or the elastic reset pulling force of the tension spring drive the upper shell 30a to slide away from the second magnetic part 46 until the upper shell 30a is blocked by the stop part 282, so that the opening of the accommodating cavity 22 is completely exposed.

[0061] In this embodiment, when the upper shell 30a covers the lower shell 20, the power circuit of the second magnetic part 46 is in a power-off state, that is, the second magnetic part 46 does not need to consume electricity; the charging device 100c only controls the power circuit of the second magnetic part 46 to be energized when the upper shell 30a is opened, and the second elastic part 37 also provides power to drive the upper shell 30a to slide. Therefore, the power consumption of the second magnetic part 46 can be further reduced, which is energy-saving and environmentally friendly.

In this embodiment, when the upper shell 30a covers the lower shell 20, the power circuit of the second magnetic member 46 is in the de-energized state, that is, the second magnetic member 46 does not need to consume power; the charging device 100 controls the power circuit of the second magnetic member 46 to be energized only when the upper shell 30a is opened, which reduces power consumption and is energy-saving and environmentally friendly.

Specifically, the first electromagnet 462 and the second electromagnet 464 are located at opposite ends of the sliding groove 28. In this embodiment, the first electromagnet 462 is located near the front plate 23 of the lower housing 20, and the second electromagnet 464 is located near the back plate 24 of the lower housing 20. The first magnetic member 44 is located between the first electromagnet 462 and the second electromagnet 464. When the upper shell 30a covers the lower shell 20, the control unit 48 controls the power circuits of the first electromagnet 462 and the second electromagnet 464 to be in a power-off state, and the magnetic relationship between the iron core of the first electromagnet 462 and the first magnetic member 44 is attraction.

[0067] When the control unit 48 receives the cover opening signal, it controls the power circuit of the first electromagnet 462 to be energized, and the magnetic relationship between the first electromagnet 46 and the first magnetic part 44 is repulsion, and the magnetic repulsion force drives the upper shell 30a to slide toward the second electromagnet 464; at the same time, the control unit 48 controls the power circuit of the second electromagnet 464 to be energized, so that the magnetic relationship between the second electromagnet 464 and the first magnetic part 44 is attraction, that is, the second electromagnet 464 can magnetically attract the first magnetic part 44, until the second electromagnet 464 and the first magnetic part 44 are adsorbed and attached to each other, and the control unit 48 controls the power circuits of the first electromagnet 462 and the second electromagnet 464 to be de-energized. In this embodiment, when the upper shell 30a covers the lower shell 20, the power circuits of the first electromagnet 462 and the second electromagnet 464 are both in a power-off state, that is, the first electromagnet 462 and the second electromagnet 464 do not need to consume electricity; after the upper shell 30a is opened, the power circuits of the first electromagnet 462 and the second electromagnet 464 are also in a power-off state, that is, the first electromagnet 462 and the second electromagnet 464 do not need to consume electricity; the charging device 100d only controls the power circuits of the first electromagnet 462 and the second electromagnet 464 to be energized by the control unit 48 during the opening process of the upper shell 30a, so that less power consumption is achieved, energy saving and environmental protection.

[0068] Specifically, when the charging device 100d has completed charging the wireless headset accommodated in the accommodating cavity 22 and the user needs to use the headset; or when the user needs to use the charging device 100d to charge the wireless headset, the user holds the user terminal close to the charging device 100d, and the user terminal will transmit an open cover signal to the charging device 100d or send the open cover signal to the control unit 48 when searching for the user terminal. The control unit 48 receives the open cover signal and controls the power circuits of the first electromagnet 462 and the second electromagnet 464 to be energized. When the first electromagnet 462 is energized, it will generate a magnetic force that repels the first magnetic part 44. When the second electromagnet 464 is energized, it will generate a magnetic force that attracts the first magnetic part 44, so as to drive the upper shell 30a to slide toward the side of the second electromagnet 464 until the upper shell 30a stops at the stop part 282. The control unit 48 controls the power circuits of the first electromagnet 462 and the second electromagnet 464 to be deenergized. At this time, after the power circuit of the second electromagnet 464 is de-energized, the first magnetic part 44 continues to be adsorbed with the iron core of the second electromagnet 464, thereby completing the automatic opening of the upper shell 30a, making it convenient for the user to take out the wireless headset from the accommodating cavity 22 or place the wireless headset into the accommodating cavity 22; there is no need to manually open the cover, which is convenient to use and improves the user experience.

[0069] In this embodiment, if the end of the first magnetic member 44 facing the first electromagnet 462 is the N pole, then the end of the first magnetic member 44 facing the second electromagnet 464 is the S pole; during the automatic opening of the upper shell 30a, the end of the first electromagnet 462 facing the first magnetic member 44 after being energized is the N pole, and the end of the second electromagnet 464 facing the first magnetic member 44 after being energized is the N pole. If the end of the first magnetic member 44 facing the first electromagnet 462 is the S pole, then the end of the first magnetic member 44 facing the second electromagnet 464 is the N pole; during the automatic opening of the upper shell 30a, the end of the first electromagnet 462 facing the first magnetic member 44 after being energized is the S pole, and the end of the second electromagnet 464 facing the first magnetic member 44 after being energized is the S pole.

[0070] In other embodiments, the first magnetic member 44 is a soft magnet, the second magnetic member 46 includes a first electromagnet 462 and a second electromagnet 464 located at opposite ends of the sliding track of the upper shell 30a, and an elastic member is provided between the upper shell 30a and the lower shell 20, and the elastic member is used to drive the upper shell 30a to slide relative to the lower shell 20 to open the cover. When the upper shell 30a covers the lower shell 20, the power circuit of the first electromagnet 462 remains energized and magnetically attracted to the soft magnetic body, so that the upper shell 30a can stably cover the lower shell 20, and the second electromagnet 464 is powered off; when the control unit 48 receives the cover opening signal, it controls the power circuit of the first electromagnet 462 to be powered off and the magnetic ineffectiveness of the soft magnetic body, and the power circuit of the second electromagnet 464 is energized, so that the second electromagnet 464 and the soft magnetic body are magnetically attracted, and the elastic part elastically pushes the upper shell 30a to slide toward the side away from the first electromagnet 462 to complete the automatic opening of the upper shell 30a.

[0071] In its embodiment, the first magnetic part 44 is a soft magnet, the second magnetic part 46 includes a first self-holding electromagnet and a second self-holding electromagnet located at opposite ends of the sliding track of the upper shell 30a, and the first magnetic part 44 and the first magnetic part 46 are provided with an elastic part, which is used to drive the upper shell 30a to slide relative to the lower shell 20 to open the cover. When the upper shell 30a covers the lower shell 20, the control unit 48 controls the power circuits of the first self-holding electromagnet and the second self-holding electromagnet to be de-energized, so that the magnetic relationship between the first magnetic part 44 and the first self-holding electromagnet is attraction, so that the upper shell 30a can stably cover the lower shell 20; when the control unit 48 receives the opening signal, the control unit 48 controls the power circuit of the first self-holding electromagnet to be energized, so that there is no magnetic force between the first self-holding electromagnet and the hard magnet, and the power circuit of the second self-holding electromagnet continues to be de-energized, so that the second self-holding electromagnet and the soft magnet are magnetically attracted, and the elastic part elastically pushes the upper shell 30a to slide toward the opening away from the accommodating cavity to complete the automatic opening of the upper shell 30a.

Specifically, the lid opening detection unit is a control key 65 disposed on the upper housing 30 or the lower housing 20. The control key 65 controls the energization state of the energized circuits of the first electromagnet 462 and the second electromagnet 464 through the control unit 48 on the mainboard 60, thereby controlling the magnetic force relationship between the first electromagnet 462 and the first magnetic member 44, and between the second electromagnet 464 and the first magnetic member 44, to automatically open or close the upper housing 30a.

[0073] The opening process and principle of the charging device 100e of this embodiment are similar to those of the sixth embodiment, except that when the control key 65 is pressed, the control key 65 sends an opening signal to the control unit 48. The control unit 48 receives the opening signal and controls the power on or off of the power circuit of the first magnetic part and the second magnetic part to achieve the control of the magnetic force relationship between the first magnetic part and the second magnetic part.

[0074] The control key 65 can also send a covering signal to the control unit 48 to control the automatic covering of the upper shell 30a. Specifically, when it is necessary to cover the upper shell 30a of the charging device 100e, the control key 65 is pressed to send a covering signal to the control unit 48. The control unit 48 receives the covering signal and controls the power circuits of the first electromagnet 462 and the second electromagnet 464, that is, controls the power circuit of the second electromagnet 464 to be energized, so that the magnetic force relationship between the first magnetic part 44 and the second electromagnet 464 is repulsive, that is, the second electromagnet 464 will generate a magnetic force that repel each other with the first magnetic part 44 after being energized; at the same time, the control unit 48 controls the power circuit of the first electromagnet 462 to be energized, so that the first magnetic part 44 and the first electromagnet 462 are repelled. The magnetic relationship between them is attraction, that is, after the first electromagnet 462 is energized, it generates a magnetic force that attracts the first magnetic part 44 to drive the upper shell 30a to slide toward one side of the first electromagnet 462 until the first electromagnet 462 and the first magnetic part 44 attract each other, and the upper shell 30a completely covers the opening of the accommodating cavity 22 of the lower shell 20, and the control part 48 controls the power circuit of the first electromagnet 462 and the second electromagnet 464 to be powered on; at this time, the first electromagnet 462 continues to be attracted to the first magnetic part 44 after being powered off, so that the covering of the upper shell 30a is stable, no manual operation is required for covering, and it is easy to use.

[0075] In other embodiments, the control key 32 may be an application icon provided on the touch screen display of the user terminal. After unlocking the user terminal, clicking the application icon causes the user terminal to send a signal, which is received by the control unit 48 on the main board 60 and controls the power circuits of the first electromagnet 462 and the second electromagnet 464 to automatically open or close the upper housing 30a.
