The examples described in the following exemplary examples do not represent all examples consistent with the present application. Rather, they are only examples of devices and methods that are consistent with some aspects of this application as detailed in the appended claims.

Example 1

Referring to FIG. 1, an example of the present application provides a charger 10, the charger 10 being used to charge an electronic device 20. The electronic device 20 may be a mobile phone, a computer, a wearable device, and the like that use electricity arbitrarily, without limitation.

The charger 10 may be a charger 10 that needs to be electrically coupled to both the power-using device and the power supply when in use, or it may be a mobile power supply that can be electrically coupled to both the power-using device and the power supply alone. Among them, the mobile power supply has a power storage function, which is applicable to various scenarios such as daily office work, travelling, and so on. Among them, the electrical connection can be a radio connection, for example, wireless charging can be realized by electromagnetic induction, electromagnetic resonance, radio waves and so on; the electrical connection can also be a wired electrical connection, for example, wired charging can be realized by means of a charging cable, a data cable and so on.

Referring to FIGS. 2 to 5, the charger 10 includes a housing 11 and a first electrical connector 12.

The housing 11 includes a cover 111 and a cassette 112, the cassette 112 is provided with an opening 1121, and the cover 111 is provided corresponding to the opening 1121; the cover 111 has a first charging surface 1111 and a first inner wall surface 1112 that is opposite to the first charging surface 1111, the cover 111 is provided with a charging port 1113 that runs through the first charging surface 1111 and the first inner wall surface 1112, and a first electrical connector 12 that is positioned corresponding to the charging port 1113.

The first electrical connector 12 and the cover 111 are movable relative to each other to switch the charger 10 between a first state and a second state, wherein in the first state, at least a portion of the first electrical connector 12 is located on one side (e.g., an outer side) of the first charging surface 1111 that is facing away or distant from the first inner wall surface 1112, as can be seen in FIGS. 2 and 3, and wherein in the second state, the first electrical connector 12 is located on another side (e.g., an inner side) of the first charging surface 1111 that is close to or facing the first inner wall surface 1112, as can be seen in FIGS. 4 and 5.

In the first state, at least a portion of the first electrical connector 12 is located on the one side of the first charging surface 1111 that is facing away or distant from the first inner wall surface 1112, the at least a portion of the first electrical connector 12 is protruding outwardly from the first charging surface 1111, which facilitates the electrical connection of the first electrical connector 12 to the electrical connection device of the electronic device 20. In the second state, the first electrical connector 12 is located on the other side of the first charging surface 1111 that is close to or facing the first inner wall surface 1112, the first electrical connector 12 is not projected outwardly from the first charging surface 1111, e.g., being flush with the first charging surface 1111 or located on the inner side of the first charging surface 1111, which may enable the housing 11 to provide a protective effect on the first electrical connector 12 to avoid wear and tear of the first electrical connector 12.

The first electrical connector 12 is an electrical connection device of the charger 10 for making an electrical connection with the electronic device 20 for charging the electronic device 20. As documented above, the electrical connection between the first electrical connector 12 and the electrical connection device of the electronic device 20 may be a wired electrical connection or a radio connection. In the example of the present application, the electrical connection between the charger 10 and the electronic device 20 is a wired electrical connection, and the first electrical connection 12 may be a pogo-pin type electrical connector, a USB type electrical connector, a type-c type electrical connector, and so on, without limitation in comparison.

It is noted that when the charger 10 is used to charge the electronic device 20, the charger 10 may be made to be in a first state so that the first electrical connector 12 of the charger 10 is electrically coupled to the electrical connection device of the electronic device 20. And when the charger 10 is idle, the charger 10 may be made to be in a second state so that the first electrical connector 12 of the charger 10 is not worn out.

In the example of the present application, the first electrical connector 12 and the cover 111 being movable relative to each other may be as follows: the cover 111 connects to the cassette 112, and the first electrical connector 12 and the housing 11 are movable relative to each other to enable the charger 10 to be switched between the first state and the second state. At this time, when the charger 10 switches between the first state and the second state, the entire housing 11 may remain motionless.

The cover 111 and the cassette 112 may be directly connected to each other or indirectly connected to each other. If the cover 111 is directly connected to the cassette 112, the two may be removably connected and so on. If the cover 111 is indirectly connected to the cassette 112, refer to FIG. 6, the charger 10 further includes a spacer 17, the spacer 17 is located in the housing 11 and is connected to the cassette 112, and the cover 111 is connected to the spacer 17 to achieve the connection between the cover 111 and the cassette 112. Among them, the cover 111 and the spacer 17 may be removably connected and so on. It should be noted that the spacer 17 needs to be set away from the first electrical connector 12 to avoid obstructing the movement of the first electrical connector 12, such as, for example, the spacer 17 is provided with an avoidance hole 171 corresponding to the first electrical connector 12, and so on.

The removable connections in the examples of the present application may all be snap-fit connections, threaded connections, and the like, without limitation.

An elastic member 16 may be connected between the carrier connected to the first electrical connector 12 and the housing 11, and the elastic member 16 may be used to drive the charger 10 to switch from the first state to the second state. For example, the elastic member 16 is designed to be in a deformed state in the first state, and the elastic member 16 is in a restored state in the second state, and the elastic restoring force of the elastic member 16 is used to realize the switching of the charger 10 from the first state to the second state, so that the switching of the charger 10 from the first state to the second state can be realized or enabled without the need for additional devices, and the structure of the charger 10 can be simplified. Among them, the elastic member 16 may be a compression spring, a shrapnel, or the like, and is not limited to any device having elasticity.

If the charger 10 is to be switched from the second state to the first state, refer to FIG. 1, the switching of the charger 10 from the second state to the first state can be achieved by the magnetic attraction force between the first anti-misalignment device 19 of the charger 10 and the second anti-misalignment device 21 of the electronic device 20 when the electronic device 20 is placed on the first charging surface 1111, so that the switching of the charger 10 from the second state to the first state can be achieved without any additional device, simplifying the structure of the charger 10. The magnetic attraction force between the first anti-misalignment device 19 and the second anti-misalignment device 21 can also make the connection between the electronic device 20 and the charger 10 more stable. Among them, the magnetic suction force of the first anti-misalignment device 19 and the second anti-misalignment device 21 can overcome the elastic force of the elastic member 16, so that the elastic member 16 can undergo deformation, so as to realize the switching of the charger 10 from the second state to the first state.

It is to be noted that in achieving the switching of the charger 10 from the second state to the first state through the magnetic attraction force between the first anti-misalignment device 19 of the charger 10 and the second anti-misalignment device 21 of the electronic device 20, it is also possible to realize the effect that the charger 10 is capable of charging the matching electronic device 20 only, e.g., the charger 10 is capable of charging only the second anti-misalignment device 21 having the matching first anti-misalignment device 19 of the electronic device 20, which can enhance the product experience and reliability of the charger 10.

Specifically, referring to FIG. 7, the first electrical connector 12 and the first anti-misalignment device 19 may be connected to the same carrier, so that when the electronic device 20 is placed on the first charging surface 1111, the first anti-misalignment device 19 and the second anti-misalignment device 21 cooperate with each other to achieve the corrective alignment between the charger 10 and the electronic device 20, and then the first anti-misalignment device 19 and the second anti-misalignment device 21 are magnetically attracted to each other, which may drive the first electrical connector 12, the first anti-misalignment device 19 and the carrier to move to realize that the charger 10 is in a first state.

The same carrier to which the first electrical connector 12 and the first anti-misalignment device 19 are connected may be the main circuit board 13, and the same carrier to which the first electrical connector 12 and the first anti-misalignment device 19 are connected may also be a device other than the main circuit board 13. Since the main circuit board 13 is provided with more electronic devices and has a larger size, if the first electrical connector 12 and the first anti-misalignment device 19 are connected to the main circuit board 13, the magnetic field strength required to achieve the movement of the main circuit board 13 with respect to the cover 111 is higher, and the requirements for the first anti-misalignment device 19 are higher, therefore, in the example of this application, the first electrical connector 12 and the first anti-misalignment device 19 are connected to the other devices outside the main circuit board 13. to other devices outside the main circuit board 13.

This makes installation easier than directly installing the first electrical connector 12 and the first anti-misalignment device 19 on the first circuit board 14.

Among them, the second mounting position may be a mounting hole and the like, without limitation. Specifically, if the first electrical connector 12 is a pogo-pin type electrical connector, the first electrical connector 12 includes a plurality of pins, and the second mounting position may include a first sub-mounting hole corresponding to each pin.

Among them, the mount 142 can be made of plastic and other materials, which has the advantages of low manufacturing cost and light weight.

In this way, when the electronic device 20 is placed on the first charging surface 1111, both poles of the first magnet 191 of the charger 10 can perform the positioning correction effect, and compared to designing the extension direction of the first magnet 191 to be perpendicular to the first charging surface 1111 so that both poles of the individual first magnets 191 can perform the positioning correction function, better positioning correction function can be achieved with fewer magnets, and the number of magnets can be reduced. In terms of the positioning correction function, the size of the charger 10 can be reduced. It should be noted that the extension direction of the first magnet 191 may also be designed to be substantially perpendicular to the first charging surface 1111, without limitation.

The first charging surface 1111 is a surface of the charger 10 for carrying the electronic device 20 when charging the electronic device 20. The first charging surface 1111 may be a plane, a curved surface, a combination of a plane and a plane, a combination of a plane and a curved surface, or a combination of a curved surface and a curved surface, and the like, without limitation.

The electronic device 20 has a second charging surface 22, the second charging surface 22 being a surface on the electronic device 20 proximate the first charging surface 1111 when the charger 10 is charging the electronic device 20.

When the first anti-misalignment device 19 includes a plurality of first magnets 191, the plurality of first magnets 191 and the plurality of second magnets can cooperate with each other to play a better positioning effect, and is conducive to improving the correction speed of the electronic device 20 on the first charging surface 1111.

Example 2

This example is substantially similar to example one, and the following description focuses on the differences between this example and example one:

Referring to FIG. 10, in this example, the first electrical connector 12 and the cover 111 are movable relative to each other as follows: the first electrical connector 12 is connected to the cassette 112, and the cover 111 is movable relative to the cassette 112 to enable the charger 10 to switch between the first state and the second state. In this example, when the charger 10 is switched between the first state and the second state, the first electrical connector 12 may remain motionless.

The first electrical connector 12 may be directly provided on and electrically coupled to the main circuit board 13 within the housing 11, simplifying the wiring process of the charger 10.

The spacer 17 is located in the housing 11 and connected to the cassette 112, the spacer 17 divides the holding chamber 113 of the housing 11 into a first chamber 1131 and a second chamber 1132, the first chamber 1131 is closer to the cover 111 than the second chamber 1132, the first chamber 1131 is connected to the charging port 1113 of the cover 111, and the spacer 17 is provided with a connection hole 172 that connects the first chamber 1131 to the second chamber 1132, the first electrical connector 12 is provided corresponding to the connection hole 172, and the cover 111 and the main circuit board 13 can be moved relative to one another to achieve the charging of the main circuit board. The first chamber 1131 is connected to the charging port 1113 of the cover 111, the spacer 17 is provided with a connecting hole 172 connecting the first chamber 1131 to the second chamber 1132, the main circuit board 13 is provided in the second chamber 1132, the first electrical connector 12 is provided in correspondence with the connecting hole 172, and the cover 111 and the spacer 17 are movable relative to each other to realize that the cover 111 and the cartridge 112 can be movable relative to each other.

In this application example, the elastic member 16 may be directly coupled between the main circuit board 13 and the cover 111, and/or, the elastic member 16 may be provided between the spacer 17 and the cover 111.

In an example of the present application, the first anti-misalignment device 19 may be coupled to at least one of the main circuit board 13, the spacer 17, and the cover 111.
