Modes for Carrying Out the Invention

[0020] To make the object, technical means, and advantages of the present application clearer, hereinafter, while referring to the embodiments of the present application, the technical means in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments that can be conceived by those skilled in the art without creative efforts all belong to the protection scope of the present application. If there is no contradiction, the following embodiments and the features in the embodiments may be combined with each other.

[0021] In order to solve the technical problem that the space occupied by charging equipment is large in the prior art, an 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, the first charging assembly includes a charging component and a moving member, the charging component is located on the moving member, the moving member is movably installed in the receiving cavity, and can extend or retract with respect to the receiving cavity. Details are described below.

[0022] Referring to FIGS. 1 to 3, FIG. 1 is a schematic configuration diagram of an embodiment of the charging device of the present application, FIG. 2 is a schematic cross-sectional configuration diagram of the charging device shown in FIG. 1 in the A-A direction, and FIG. 3 is a schematic configuration diagram of the charging device shown in FIG. 1 in another state.

[0023] In one embodiment, the charging device includes a housing assembly 10. The housing assembly 10 serves as the basic carrier of the charging device and plays a role in placing and protecting other components of the charging device. A receiving cavity 11 is installed inside the housing assembly 10.

[0024] The charging device further includes a first charging assembly 20. The first charging assembly 20 includes a charging component 21 and a moving member 22. The charging component 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 extend or retract with respect to the receiving cavity 11. As shown in FIG. 3, as the moving member 22 extends with respect to the receiving cavity 11, the charging component 21 extends outside the housing assembly 10 together with the moving member 22. In this case, the charging component 21 can charge an electronic device. As shown in FIGS. 1 and 2, after charging is completed, the moving member 22 can retract with respect to the receiving cavity 11, and the charging component 21 retracts into the receiving cavity 11 together with the moving member 22.

[0025] As can be seen from the above, since the movable member 22 of this embodiment can be retracted into the housing cavity 11, the overall volume of the charging device is reduced, meaning that the space occupied by the charging device is small and it is easy for the user to carry and use. Furthermore, even when the movable member 22 is extended, the charging device of this embodiment still has a small volume and is easy for the user to use.

[0026] Preferably, the charging component 21 may be a wireless charging component, and the charging component 21 charges electronic devices such as smartwatches using a wireless charging method. The charging component 21 may also support MagSafe charging connection technology, and electronic devices with magnetic attraction capabilities can establish an electrical connection and begin charging by approaching the charging component 21 and attracting it to the charging component 21.

[0027] Referring to Figure 4 as a whole, Figure 4 is a schematic configuration diagram of one embodiment of the movable member of the present application.

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

[0029] Referring to Figure 5 as a whole, Figure 5 is a schematic cross-sectional view of the charging device shown in Figure 3 in the BB direction.

[0030] An opening 12 and a second contact portion 13 are further provided in the housing assembly 10. The opening 12 communicates with the housing cavity 11, that is, the opening 12 connects the housing cavity 11 to the outside of the housing assembly 10, and the movable member 22 extends from the housing cavity 11 through the opening 12 and retracts into the housing cavity 11 through the opening 12. The second contact portion 13 is adjacent to the opening 12, in other words, the second contact portion 13 is the housing assembly 10 around the opening 12.

[0031] As the movable member 22 extends from the opening 12 toward the housing cavity 11, the first contact portion 222 abuts against the second contact portion 13, restricting further extension of the movable member 22 toward the housing cavity 11 and preventing the movable member 22 from separating from the housing cavity 11, i.e., preventing the movable member 22 from completely escaping from the housing cavity 11. In this way, after the movable member 22 extends toward the housing cavity 11, the engagement and contact between the first contact portion 222 and the second contact portion 13 ensures that the movable member 22 securely holds the electronic device and allows the charging component 21 to charge the electronic device.

[0032] For example, the charging component 21 may charge an electronic device such as a smartwatch. Specifically, the dial of the smartwatch is placed on the movable member 22 and positioned on the opposite side of the charging component 21, so that the movable member 22 can support the smartwatch and the charging component 21 can charge the smartwatch.

[0033] Furthermore, as shown in Figure 4, the first contact portion 222 is provided around the outer circumference of the movable member body 221. The movable member 22 may be composed of two parts, an upper housing and a lower housing. That is, since both the movable member body 221 and the first contact portion 222 are composed of two parts, an upper housing and a lower housing, it is easy to attach the charging component 21 to the movable member 22.

[0034] Referring to Figure 6 as a whole, Figure 6 is a schematic cross-sectional view of the charging device shown in Figure 3 in the CC direction.

[0035] In one embodiment, the first charging assembly 20 further includes an elastic member 23. A movable member 22 is connected to the housing assembly 10 via the elastic member 23, which causes the movable member 22 to tend to extend toward the housing cavity 11, i.e., drives the movable member 22 to extend toward the housing cavity 11. In other words, the elastic restoring force provided by the elastic member 23 drives the movable member 22 to extend toward the housing cavity 11, allowing the user to easily eject the movable member 22 and charge the electronic device using the charging component 21, making the charging device of this embodiment even easier to use.

[0036] With respect to the first contact portion 222 and the second contact portion 13 described in the above embodiment, the elastic member 23 of this embodiment drives the movable member 22 to extend out of the housing cavity 11 until the first contact portion 222 of the movable member 22 contacts the second contact portion 13 of the housing assembly 10, and limits the movable member 22 from extending further out of the housing cavity 11. At this time, the elastic restoring force provided by the elastic member 23 is advantageous in that it can maintain the movable member 22 in an extended state out of the housing cavity 11, ensuring that the movable member 22 securely places the electronic equipment during the charging process and reducing the risk of the movable member 22 accidentally retracting into the housing cavity 11 due to the influence of external forces.

[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 the surface of the housing assembly 10 facing the opening 12. The position limiting rod 24 is also inserted into the movable member 22, and the position limiting rod 24 extends along the direction of movement of the movable member 22 (as shown by arrow X in Figure 6, the same applies hereafter), and the movable member 22 is movable along the position limiting rod 24. The elastic member 23 is fitted onto the outer circumference of the position limiting rod 24 and is interposed between the movable 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, the two sets of elastic members 23 and position limiting rods 24 being installed on opposite sides of the housing cavity 11, that is, one set of elastic members 23 and position limiting rods 24 being located on one side of the housing cavity 11, and the other set of elastic members 23 and position limiting rods 24 being located on the other side of the housing cavity 11.

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

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

[0041] Next, refer to Figures 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 movable member 22. Furthermore, the press-type latch 25 is located within the space formed by the movable member body 221, and the first contact portion 222 is provided around the outer circumference of the press-type latch 25. The buckle 26 is located within the housing cavity 11.

[0042] A self-locking design is used for the press-type latch 25. As shown in Figure 2, when the press-type latch 25 is pressed against the buckle 26, the press-type latch 25 engages with the buckle 26 and locks. As shown in Figure 6, when the press-type latch 25 is pressed against the buckle 26 again, the press-type latch 25 releases the buckle 26 and the lock is released. Specifically, after the movable member 22 has retracted, when the press-type latch 25 is pressed against the buckle 26, it engages with the buckle 26 and locks the movable member 22. When the press-type latch 25 is pressed against the buckle 26 again due to the action of pressure, the press-type latch 25 releases the lock from the buckle 26 and allows the movable member 22 to extend.

[0043] For example, before the user uses the first charging assembly 20, the movable member 22 retracts into the housing cavity 11, at which point the press latch 25 and the buckle 26 engage to lock the movable member 22. When the user needs to charge the electronic device using the first charging assembly 20, the user presses the movable member 22, thereby pressing the press latch 25 against the buckle 26, at which point the lock between the press latch 25 and the buckle 26 is released, as shown in Figure 6, and the movable member 22 extends out of the housing cavity 11 by the drive of the elastic member 23, allowing the user to charge the electronic device using the first charging assembly 20. After charging is complete, the user pushes the movable member 22 back into the housing cavity 11, at which point the press latch 25 is pressed against the buckle 26 again, as shown in Figure 2, and the press latch 25 engages with the buckle 26 again to lock the movable member 22.

[0044] The self-locking design of the push-type latch 25 is within the realm of understanding for those skilled in the art, and therefore will not be explained here.

[0045] Referring to Figures 1, 2, and 7, Figure 7 is a schematic diagram of a further configuration of the charging device shown in Figure 1.

[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 housing cavity 11 and opening 12 are also mounted on the housing body 14.

[0047] Furthermore, as shown in Figure 6, the housing assembly 10 further includes a damper pivot shaft 16. The flip cover 15 is rotatably mounted on the housing body 14 via the damper pivot shaft 16. The damper pivot 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 has rotated relative to the housing body 14.

[0048] The specific design of the damper rotation shaft 16 is within the realm of understanding for those skilled in the art, and therefore will not be explained 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, the surface of the flip cover 15 away from the housing body 14 is the 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 electronic devices such as smartphones using a wireless charging method. The second charging component 21 may also support MagSafe charging connection technology, and electronic devices with magnetic attraction capabilities can approach the first mounting surface 151 of the flip cover 15, attract to the first mounting surface 151, establish an electrical connection with the second charging component 21, and begin charging.

[0051] Furthermore, since the flip cover 15 is rotatable relative to the housing body 14, the user can flip the flip cover 15 so that the first mounting surface 151 of the flip cover 15 and the horizontal plane form a certain angle (as shown in Figure 7), and then attach an electronic device such as a smartphone to the first mounting surface 151, placing the smartphone at a certain angle. At this time, the user can not only easily receive the content displayed on the smartphone, but also charge the smartphone 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 on 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 the 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 the electronic device to be placed on the second mounting surface 141 and charged by 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 electronic devices with magnetic attraction capabilities can approach the second mounting surface 141 of the housing body 14, attract to the second mounting surface 141, establish an electrical connection with the third charging component 21, and be charged.

[0055] 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 Figure 7, the user can place a smartwatch on the first charging assembly 20 and charge it by operating the movable member 22 of the first charging assembly 20 to pop it out of the housing assembly 10. The user can then place a smartphone on the first mounting surface 151 of the flip cover 15 by flipping the flip cover 15 over and charge the smartphone with the second charging assembly 30. After flipping the flip cover 15 over, the second mounting surface 141 of the housing body 14 can be opened, and earphones (e.g., TWS earphones) can be placed on the second mounting surface 141 of the housing body 14 and charged with the third charging assembly 40. Because the structures of the first charging assembly 20, the second charging assembly 30, and the third charging assembly 40 are compact, the overall volume of the charging device is small, and the space occupied by the charging device is small. In other words, the charging device of this embodiment can realize a charging module design that combines three functions for smartwatches, smartphones, and earphones into one unit in a small volume.

[0056] Next, refer to Figures 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 supply and transmits power supplied from the external power supply to the charging components 21 via the circuit board 61.

[0057] In other words, the charging device of this embodiment does not have a power supply installed, 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 power must be supplied from the external power supply to charge the electronic equipment. The charging device of this embodiment saves space occupied by the power supply, further reduces the volume of the charging device, reduces the space occupied by the charging device, and is also easier for the user to carry and use.

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

[0059] As described above, the charging device according to the present invention reduces the overall volume of the charging device because its movable member can be retracted into the housing cavity. In other words, the charging device has a small volume, occupies less space, and is easy for the user to carry and use. Furthermore, even when the movable member is extended, the charging device of the present invention still has a small volume and is easy for the user to use.

[0060] Furthermore, the charging device of this application can realize a charging module design that combines three functions for smartwatches, smartphones, and earphones into one unit in a small volume. The first, second, and third charging assemblies of the charging device have a novel structure and possess excellent scientific and technological features and playability.

[0061] Furthermore, unless otherwise explicitly stated or limited, terms such as "connection," "joining," and "lamination" should be understood in a broad sense. For example, these may include fixed connections, detachable connections, or integral connections; they may include direct connections, indirect connections via an intermediate medium, or internal communication between two parts or the interaction between two parts. Those skilled in the art will be able to understand the specific meaning of these terms in this application depending on the specific circumstances.

[0062] The above embodiments are merely for illustrating the technical means of the present application and are not intended to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical means described in the above embodiments or substitute some or all of their technical features with equivalents, 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 the embodiments of the present application.
