[0020] In order to make the objectives, technical means and advantages of the present application clearer, the following will clearly and completely describe the technical means in the embodiments of the present application with reference to the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, and are not all of the embodiments. Based on the embodiments of the present application, all other embodiments that a person skilled in the art can think of without creative effort are all within the scope of protection of the present application. If not inconsistent, the following embodiments and features in the embodiments may be combined with each other.

[0021] In order to solve the technical problem that the charging equipment occupies a large space in the prior art, one embodiment of the present application provides a charging device. The charging device includes a housing assembly, and a receiving cavity is installed inside the housing assembly. The charging device further includes a first charging assembly, and the first charging assembly includes a charging part and a moving member, the charging part is located on the moving member, and the moving member is movably installed in the receiving cavity and can extend or retract with respect to the receiving cavity. The details are described below.

[0022] Referring to Figures 1 to 3, Figure 1 is a schematic diagram of one embodiment of the charging device of the present application, Figure 2 is a schematic cross-sectional diagram of the charging device shown in Figure 1 in the AA direction, and Figure 3 is a schematic diagram of the charging device shown in Figure 1 in another state.

[0023] In one embodiment, the charging device includes a housing assembly 10. The housing assembly 10 serves as a base carrier for the charging device, to mount and protect other components of the charging device. A receiving cavity 11 is disposed within the housing assembly 10.

[0024] The charging device further includes a first charging assembly 20. The first charging assembly 20 includes a charging part 21 and a moving member 22. The charging part 21 is located on the moving member 22, and the moving member 22 is movably installed in the receiving cavity 11. The moving member 22 can be extended or retracted relative to the receiving cavity 11. As shown in FIG. 3, as the moving member 22 extends relative to the receiving cavity 11, the charging part 21 extends to the outside of the housing assembly 10 together with the moving member 22, in this case, the charging part 21 can charge the electronic device. As shown in FIG. 1 and FIG. 2, after charging is completed, the moving member 22 can be retracted relative to the receiving cavity 11, and the charging part 21 retracts to the receiving cavity 11 together with the moving member 22.

[0025] As can be seen from the above, the movable member 22 of this embodiment can be retracted into the receiving cavity 11, thereby reducing the overall volume of the charging device, i.e., the space occupied by the charging device is small, making it easy for users to carry and use. In addition, even if the movable member 22 is extended, the charging device of this embodiment still has a small volume, making it easy for users to use.

[0026] Preferably, the charging component 21 may be a wireless charging component, and the charging component 21 charges an electronic device such as a smart watch by a wireless charging method. The charging component 21 may support MagSafe charging connection technology, and an electronic device having a magnetic attraction function can be attracted to the charging component 21 by itself when it is close to the charging component 21, establish an electrical connection, and perform charging.

[0027] Referring to FIG. 4, FIG. 4 is a schematic diagram of an embodiment of a moving member of the present application.

[0028] In one embodiment, the moving member 22 includes a moving member body 221 and a first contact portion 222. The first contact portion 222 protrudes from the moving member body 221. The charging part 21 is located on the moving member body 221.

[0029] 5. Referring to FIG. 5 as a whole, FIG. 5 is a schematic cross-sectional configuration diagram of the charging device shown in FIG. 3 taken along the line BB.

[0030] The housing assembly 10 is further provided with an opening 12 and a second abutment portion 13. The opening 12 communicates with the receiving cavity 11, i.e., the opening 12 communicates the receiving cavity 11 with the outside of the housing assembly 10, and the moving member 22 extends from the receiving cavity 11 through the opening 12 and retracts into the receiving cavity 11 through the opening 12. The second abutment portion 13 is adjacent to the opening 12, in other words, the second abutment portion 13 is the housing assembly 10 around the opening 12.

[0031] As the moving member 22 extends from the opening 12 into the accommodating cavity 11, the first abutment portion 222 abuts against the second abutment portion 13 to restrict the moving member 22 from extending further into the accommodating cavity 11 and prevent the moving member 22 from being separated from the accommodating cavity 11, i.e., prevent the moving member 22 from completely escaping from the accommodating cavity 11. In this manner, after the moving member 22 extends into the accommodating cavity 11, the first abutment portion 222 and the second abutment portion 13 engage and abut against each other, so that the moving member 22 can reliably place the electronic device on it and charge the electronic device by the charging component 21.

[0032] For example, the charging part 21 may charge an electronic device such as a smart watch. Specifically, the dial of the smart watch is placed on the moving member 22 and positioned on the opposite side of the charging part 21, and at this time, the moving member 22 places the smart watch on it, and the charging part 21 can charge the smart watch.

[0033] 4, the first contact portion 222 is provided around the outer periphery of the moving member body 221. The moving member 22 may be composed of two parts, an upper housing and a lower housing. That is, since the moving member body 221 and the first contact portion 222 are both composed of two parts, an upper housing and a lower housing, the charging component 21 can be easily attached to the moving member 22.

[0034] 6, FIG. 6 is a schematic cross-sectional view of the charging device shown in FIG. 3 taken along the CC direction.

[0035] In one embodiment, the first charging assembly 20 further includes an elastic member 23. The moving member 22 is connected to the housing assembly 10 via the elastic member 23, and the elastic member 23 causes the moving member 22 to have a tendency to extend toward the accommodating cavity 11, i.e., drives the moving member 22 to extend toward the accommodating cavity 11. In other words, the elastic restoring force provided by the elastic member 23 drives the moving member 22 to extend from the accommodating cavity 11, so that the user can easily pop out the moving member 22 and charge the electronic device using the charging component 21, which makes it easier for the user to use the charging device of this embodiment.

[0036] With respect to the first abutment portion 222 and the second abutment portion 13 described in the above embodiment, the elastic member 23 in this embodiment drives the moving member 22 to extend from the accommodating cavity 11 until the first abutment portion 222 of the moving member 22 abuts against the second abutment portion 13 of the housing assembly 10, and restricts the moving member 22 from further extending into the accommodating cavity 11. At this time, the elastic restoring force provided by the elastic member 23 can maintain the moving member 22 in a state extended from the accommodating cavity 11, which is advantageous in ensuring that the moving member 22 reliably places the electronic device during the charging process and reducing the risk of the moving member 22 erroneously retracting into the accommodating cavity 11 due to the influence of an external force.

[0037] Furthermore, the first charging assembly 20 further includes a position limiting rod 24. One end of the position limiting rod 24 is fixed to the housing assembly 10. Specifically, the one end of the position limiting rod 24 is fixed to a surface of the housing assembly 10 facing the opening 12. The position limiting rod 24 is inserted into the moving member 22, and extends along the moving direction of the moving member 22 (as shown by arrow X in FIG. 6, the same applies below), and the moving member 22 is movable along the position limiting rod 24. The elastic member 23 is fitted onto the outer periphery of the position limiting rod 24 and is interposed between the moving member 22 and the housing assembly 10, and the position limiting rod 24 can limit the position of the elastic member 23.

[0038] For example, the first charging assembly 20 includes two sets of elastic members 23 and position limiting rods 24, which are respectively installed on opposite sides of the accommodating cavity 11, i.e., one set of elastic members 23 and position limiting rods 24 is located on one side of the accommodating cavity 11, and the other set of elastic members 23 and position limiting rods 24 is located on the other side opposite the accommodating cavity 11.

[0039] Preferably, the elastic member 23 may be a spring or the like, and is not limited thereto.

[0040] 4 and 6. In one embodiment, a slider 223 is installed on the moving member 22, a slide rail 224 is installed in the receiving cavity 11, and the slider 223 and the slide rail 224 are slidably connected. The slide rail 224 extends along the moving direction of the moving member 22, the slider 223 is slidable along the slide rail 224 as the moving member 22 moves, and the slide rail 224 guides the movement of the moving member 22.

[0041] 2 and 6. In one embodiment, the first charging assembly 20 further includes a press-type latch 25 and a buckle 26. The press-type latch 25 is located on the moving member 22. Furthermore, the press-type latch 25 is located in a space surrounded and formed by the moving member body 221, and the first abutment portion 222 is provided around the outer periphery of the press-type latch 25. The buckle 26 is located in the receiving cavity 11.

[0042] The press latch 25 is designed to be self-locking. When the press latch 25 is pressed against the buckle 26, as shown in Fig. 2, the press latch 25 can engage with the buckle 26 to lock it, and when the press latch 25 is pressed against the buckle 26 again, as shown in Fig. 6, the press latch 25 can release the buckle 26 to unlock it. Specifically, when the press latch 25 is pressed against the buckle 26 after the moving member 22 retreats, it can engage with the buckle 26 to lock the moving member 22, and when the press latch 25 is pressed against the buckle 26 again under the action of pressure, the press latch 25 can unlock the buckle 26 to allow the moving member 22 to extend.

[0043] For example, before a user uses the first charging assembly 20, the moving member 22 retreats into the receiving cavity 11, and at this time, the press-type latch 25 and the buckle 26 engage with each other to lock the moving member 22. When a user needs to use the first charging assembly 20 to charge an electronic device, the user presses the moving member 22 to press the press-type latch 25 against the buckle 26, and at this time, as shown in FIG. 6, the press-type latch 25 and the buckle 26 are unlocked, and the moving member 22 extends from the receiving cavity 11 by being driven by the elastic member 23, allowing the user to charge the electronic device using the first charging assembly 20. After charging is completed, the user pushes the moving member 22 back into the receiving cavity 11, and at this time, as shown in FIG. 2, the press-type latch 25 is pressed against the buckle 26 again, and the press-type latch 25 engages with the buckle 26 again to lock the moving member 22.

[0044] The self-locking design of the pressure latch 25 is within the understanding of those skilled in the art, so a detailed description thereof will be omitted here.

[0045] 1, 2 and 7, FIG. 7 is a schematic diagram of the charging device shown in FIG. 1 in a further state.

[0046] In one embodiment, the housing assembly 10 includes a housing body 14 and a flip cover 15. The flip cover 15 is rotatably mounted on the housing body 14. The first charging assembly 20 is mounted on the housing body 14, and the corresponding receiving cavity 11 and opening 12 are also mounted on the housing body 14.

[0047] 6, the housing assembly 10 further includes a damper rotating shaft 16. The flip cover 15 is rotatably mounted on the housing body 14 via the damper rotating shaft 16. The damper rotating shaft 16 provides a damping force to maintain the relative position between the flip cover 15 and the housing body 14 after the flip cover 15 rotates with respect to the housing body 14.

[0048] The specific design of the damper rotating shaft 16 is within the scope of understanding of those skilled in the art, so a detailed description thereof will be omitted here.

[0049] In one embodiment, the charging device further includes a second charging assembly 30. The first charging assembly 20 and the second charging assembly 30 each charge different electronic devices. Specifically, a surface of the flip cover 15 away from the housing body 14 is a first mounting surface 151. The second charging assembly 30 is installed on the flip cover 15 and charges the electronic device placed on the first mounting surface 151.

[0050] Preferably, the second charging component 21 may be a wireless charging component, and the second charging component 21 charges an electronic device such as a smartphone by wireless charging. The second charging component 21 may also support MagSafe charging connection technology, and an electronic device having a magnetic adsorption function can be attracted to the first mounting surface 151 of the flip cover 15 by itself when it approaches the first mounting surface 151, establish an electrical connection with the second charging component 21, and perform charging.

[0051] Furthermore, since the flip cover 15 is rotatable relative to the housing main body 14, the user can flip the flip cover 15 over so that the first mounting surface 151 of the flip cover 15 forms a certain angle with the horizontal plane (as shown in FIG. 7), and then the user can attach an electronic device such as a smartphone to the first mounting surface 151 and place the smartphone at a certain angle.At this time, not only can the user easily view the display content displayed on the smartphone, but the smartphone can also be charged at the same time.

[0052] In one embodiment, the surface of the housing body 14 facing the flip cover 15 is the second mounting surface 141. The charging device further includes a third charging assembly 40, which is installed in the housing body 14 and is closer to the second mounting surface 141 than the first charging assembly 20, and the third charging assembly 40 charges an electronic device placed on the second mounting surface 141.

[0053] When the flip cover 15 is placed over the housing body 14, the flip cover 15 is stacked on the second mounting surface 141 of the housing body 14, and when the flip cover 15 is rotated and flipped over relative to the housing body 14, the second mounting surface 141 of the housing body 14 is exposed from the flip cover 15, allowing an electronic device to be placed on the second mounting surface 141 and charging the electronic device with the third charging assembly 40.

[0054] Preferably, the third charging component 21 may be a wireless charging component, and the third charging component 21 charges electronic devices such as TWS earphones by wireless charging. The third charging component 21 may also support MagSafe charging connection technology, and an electronic device having a magnetic adsorption function can be attracted to the second mounting surface 141 of the housing body 14 by itself when it approaches the second mounting surface 141, establish an electrical connection with the third charging component 21, and perform charging.

[0055] In addition, the first charging assembly 20, the second charging assembly 30, and the third charging assembly 40 each charge different electronic devices. In other words, in this embodiment, the first charging assembly 20, the second charging assembly 30, and the third charging assembly 40 can charge three electronic devices simultaneously. For example, as shown in FIG. 7, a user can place a smart watch on the first charging assembly 20 to charge it by operating the moving member 22 of the first charging assembly 20 so as to flip it out of the housing assembly 10, and then the user can place a smartphone on the first mounting surface 151 of the flip cover 15 by turning over the flip cover 15, and charge the smartphone with the second charging assembly 30, and then, after turning over the flip cover 15, the second mounting surface 141 of the housing main body 14 can be opened, and an earphone (e.g., a TWS earphone) can be placed on the second mounting surface 141 of the housing main body 14, and the earphone can be charged with the third charging assembly 40. Because the first charging assembly 20, the second charging assembly 30 and the third charging assembly 40 have a compact structure, the overall volume of the charging device is small and the space occupied by the charging device is small, that is, the charging device of this embodiment can realize a charging module design that combines three functions of a smart watch, a smartphone and earphones into one in a small volume.

[0056] 1 and 2. In one embodiment, the charging device further includes a circuit board 61 and a power interface 62. The circuit board 61 is installed in the housing assembly 10 and is electrically connected to the power interface 62. The first charging assembly 20, the second charging assembly 30 and the third charging assembly 40 are all electrically connected to the circuit board 61. The power interface 62 is electrically connected to an external power source and transmits power supplied from the external power source to the charging component 21 via the circuit board 61.

[0057] In other words, no power supply is installed in the charging device of this embodiment, and the first charging assembly 20, the second charging assembly 30 and the third charging assembly 40 are all electrically connected to an external power supply via the circuit board 61 and the power interface 62, and need to supply power from the external power supply to charge the electronic devices. The charging device of this embodiment saves the space occupied by the power supply, further reduces the volume of the charging device, reduces the space occupied by the charging device, and is more convenient for users to carry and use.

[0058] Of course, in other embodiments of the present application, a power source may be installed inside the housing assembly 10 of the charging device, and the power source may power the first charging assembly 20, the second charging assembly 30, and the third charging assembly 40, and further charge the electronic device, and is not limited thereto.

[0059] As described above, the charging device according to the present application has a movable member that can retract into the receiving cavity, thereby reducing the overall volume of the charging device, i.e., the volume of the charging device is small, the space it occupies is small, and it is easy for users to carry and use. Even if the movable member is extended, the charging device according to the present application still has a small volume and is easy for users to use.

[0060] In addition, the charging device of the present application can realize a charging module design that integrates three functions of a smart watch, a smartphone and an earphone in one with a small volume. The first charging assembly, the second charging assembly and the third charging assembly of the charging device have a novel structure, and have excellent technological sense and playability.

[0061] In addition, in this application, unless otherwise clearly specified and limited, the terms "connection", "connection", "lamination", etc. should be understood in a broad sense, and may be, for example, a fixed connection, a detachable connection, an integral connection, a direct connection, an indirect connection via an intermediate medium, an internal communication between two parts, or an interaction relationship between two parts. A person skilled in the art can understand the specific meaning of the above terms in this application according to the specific situation.

[0062] It should be noted that the above embodiments are merely for the purpose of explaining the technical means of the present application, and are not intended to limit the same. Although the present application has been described in detail with reference to the above embodiments, a person skilled in the art may still modify the technical means described in the above embodiments, or equivalently replace some or all of the technical features thereof, and such modifications or changes will not cause the essence of the corresponding technical means to deviate from the scope of the technical means of each embodiment of the present application.
