[0043] FIG. 1 is an exploded view of the charging stand 10, according to an embodiment of the present invention. FIG. 2 is a schematic diagram illustrating the connection of the charging stand 10 and the electronic device 15, according to an embodiment of the present invention.

[0044] As shown in FIG. 1, the charging stand 10 of the present invention includes a base 101, a housing 102, a circuit board 104, and a rotatable connector 106. The housing 102 is formed with an opening 1020, and a plurality of sidewalls of the housing are engaged with a periphery of the base 101. There is provided with an accommodation space in an interior of the housing, which can accommodate a circuit board 104, a rotatable connector 106, and other required elements. In other words, the longitudinal cross section of the housing 102 appears as an inverse-U shape to cover the base 101. The circuit board 104 is provided on the base 101, and can be connected to an external power supply. The power that supplies to the charging stand 10 is typically DC power. In general, a transformer (not illustrated) or a rectifier (not illustrated) may be used to convert AC power into DC power. The rotatable connecter is pivotally connected to the base 101, and it is located corresponding to the position of the opening 1020, so the rotatable connector 106 will become visible from the opening 1020 when observing from the top. In addition, the rotatable connector 106 is electrically connected to the circuit board 104. There is further included a heat dissipation hole 1021 on a side of the housing, adjacent to the opening, used to dissipate the heat generated by charging.

[0045] The charging stand 10 is a device suitable for being connected to the electronic device 15 and charging the electronic device 15. In the present specification, a connected state refers to a state that the charging stand 10 is enabled to be connected to an electronic device 15; a stored state refers to a state that the rotatable connector 106 of the charging stand 10 is being rotated below the opening 1020.

[0046] With reference to FIG. 2, the charging stand 10 is connected, mainly by the rotatable connector 106, to an electronic device 15, so that it can be charged. In the connected state, the rotatable connector 106 partially extends out of the opening 1020. In FIG. 1 and FIG. 2, a portable audio is cited as an example for the electronic device 15, but the present invention is not limited thereto. The charging stand 10 may also suitably be connected to other devices such as a Wi-Fi router or a set-top box.

[0047] In addition, it should also be noted that the arrangement of the charging stand 10 of the present invention is equipped with the rotatable connector 106 pivotally connected to the base 101, which can be realized by any feasible structure. In the stored state (including the uncharged state), the charging stand 10 is no longer connected to the electronic device 15, and, at this moment, the rotatable connector 106 can be downwardly rotated and stored below the opening 1020 (as shown in FIG. 3A). In comparison with the prior arts, the charging stand 10 is more aesthetically pleasing. Besides, when it needs to be stored in a bag or packet, it will no longer hook other objects by the protruding connector. Moreover, it also saves the storage space.

[0048] With reference to FIG. 1 and FIG. 2, in order to make the engagement (including electrical connection and physical connection) between the charging stand 10 and the electronic device 15 stable, the housing 102 may further include a plurality of recesses 1022, and the electronic device 15 may further include a plurality of protrusions 152. The recesses 1022 are distributed adjacent to the corners or the periphery of the housing 102. In the connected state, on one hand, the recesses 1022 and the protrusions 152 are completely engaged with each other, enabling the electrical connection of the rotatable connector 106 and the electronic device 10 to be more stable. On the other hand, it enables the physical engagement between the charging stand 10 and the electronic device 15 to be more stable. As such, when the charging stand 10 is installed in a moving object such as a vehicle, the electronic device will not be separated therefrom just by a slight vibration. Of course, the plurality of the recesses 1022 provided on the housing 102 and the plurality of the protrusions 152 of the electronic device 15 may be accomplished by opposite structures, that is, the housing 102 may be arranged with a plurality of protruding components, and the electronic device 15 may be arranged with a plurality of recessing components, to produce the same effects mentioned above.

[0049] Next, please see FIGS. 3A, 3B, and 3C with reference to FIG. 1. FIG. 3A is a schematic diagram of the locked state of the charging stand 10, according to an embodiment of the present invention. FIG. 3B is a schematic diagram of the unlocked state of the charging stand 10, according to an embodiment of the present invention. FIG. 3C is a schematic diagram of the locked state of the charging stand 10, according to another embodiment of the present invention.

[0050] The charging stand 10 of the present invention may further include a moveable lock piece 108, set to extend across two sides of the opening 1020. There are a locked state and an unlocked state defined for the moveable lock piece 108. The locked state means the connector 106 is locked by the moveable lock piece 108, and thus, is not allowed to freely rotate; the unlocked state means the connector is not locked, and thus, is allowed to freely rotate. For example, as shown in FIG. 3A, when the moveable lock piece 108 retracts into the opening 1020, the connector 106 is in the locked state; conversely, as shown in FIG. 3B, when the moveable lock piece 108 laterally extends out of the opening 1020, the connector 106 is in the unlocked state.

[0051] More specifically, in the locked state, the moveable lock piece 108 is fixed across the two sides of the opening 1020. Both in the situation that the rotatable connector 106 is parallel to the base 101 (such as the stored state shown in FIG. 3A), and in the situation that the rotatable connector 106 is perpendicular to the base 101, the rotatable connector 106 is not allowed to rotate. In the unlocked state, the moveable lock piece 108 extending out of the housing 102, the opening 1020 is no longer locked by the lock piece 108, and, at the moment, the rotatable connector 106 is enabled to freely rotate, so as to be parallel or perpendicular to the base 101.

[0052] In addition to using the moveable lock piece 108 to form the locked state or the unlocked state, in another embodiment, the rotatable connector 106 may have a bouncing structure, configured such that: when being applied by an instantly pressing pressure, the rotatable connector can be triggered (for example to bounce up) to switch from a parallel state to a perpendicular state for the latter connection. The bouncing structure may further have a buckle function, configured such that: when being applied by a push, it will slowly lie down from the perpendicular state and restore to be the parallel state.

[0053] Please referring back to FIG. 1, the charging stand 10 may further include a battery cell module 109. The battery cell module 109 is connected to the circuit board 104, and the circuit board 104 can be configured such that: when being connected to the external power supply, the power supply module 109 and the electronic device 15 are simultaneously charged by the external power supply; when not being connected to the external power supply, the electronic device 15 is charged by the battery cell module 109. Apparently, the battery cell module 109 can serve as a back-up power supply. If the external power supply fails to work, the battery cell module 109 can serve as the back-up power supply to charge for the electronic device 15.

[0054] FIG. 4 is a schematic diagram of the electronic apparatus 1 formed by the connection of the charging stand 10 and the electronic device 15, according to an embodiment of the present invention.

[0055] As shown in FIG. 4, the charging stand 10 of the present invention may be combined with an electronic device 15 to form an electronic apparatus 1. Under a conceptual framework that the charging stand 10 and the electronic device 15 are integrally designed, the electronic apparatus 1 will have a uniform and aesthetical appearance. FIG. 4 cites a portable audio device for an example. When the charging stand 10 is disposed in a vehicle, the audio device 15 can be charged during driving (playing music and being charged can be at a same time). It is safely and firmly stable. Furthermore, after arriving in the destination, the portable audio has sufficient power so that it can be carried around to play music. So, it is very convenient.

[0056] Admittedly, the shapes of the charging stand 10 and the electronic device 15 can be different, but preferably they are the same. In FIG. 4, the charging stand 10 and the electronic device 15 may both be cuboid. In another embodiment, the charging stand 10 and the electronic device 15 may both be cylinder. The area of the cross section of the charging stand 10 can be larger than that of the electronic device 15, so as to maintain its stability.

Method

[0057] According to the description of the aforementioned embodiments, still another embodiment of the present invention provides a method for the operation of the charging stand 10, performed by using the charging stand of one embodiment, and the method includes following steps:

[0058] Step S1: unlocking the lock of the rotatable connector 106 to allow the rotatable connector 106 to rotate;

[0059] Step S2: rotating the rotatable connector 106; and

[0060] Step S3: connecting an electronic device 15 to the charging stand 10.

[0061] The lock in the Step S1 can be performed by a moveable lock piece 108 or a bouncing structure.

[0062] The connection in the Step S3 is aligning the plurality of the protrusions 152 of the electronic device 15 to the plurality of the recesses 1022 of the housing 102.

[0063] To sum up, the charging stand of the present invention has the plurality of the recesses that are favorable to the engagement and has the rotatable connector. In the connected state, those can ensure the engagement of the electronic device to be stable and secure; in the stored state, the rotatable connector can be rotated below the opening and hidden into the housing of the charging stand. It is uniform and neat in appearance so that the required storage space can be saved.

[0064] Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
