Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring embodiments of the present invention.

In the following description, a detailed structure will be presented for a thorough understanding of the embodiments of the present invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

The utility model provides a charging device 10, it constructs to use angularly adjustable, can protect the internal circuit simultaneously to charging device 10's maneuverability and durability have been improved.

Referring first to fig. 1 and 2, a charging device 10 according to the present invention includes a charging panel 12 and a bracket 14. The charging panel 12 is used to hold a charged device and is electrically connected to the charged device to supply power thereto. The stand 14 is pivotally connected to the charging panel 12 and supports the charging panel 12 on a suitable work surface, such as a table top.

The relative angle between the charging panel 12 and the bracket 14 is adjustable. For this purpose, the charging panel 12 has a stopper hole 28, and the bracket 14 has a stopper pin 30 (see fig. 4). In the assembled state of the charging device 10, the stopper pin 30 of the bracket 14 is engaged in the stopper hole 28 of the charging panel 12, and the stopper pin 30 is movable relative to the stopper hole 28, so that the charging panel 12 can be angularly adjusted relative to the bracket 14. The charging panel 12, which is angularly adjustable with respect to the bracket 14, has an adjustment position within a certain limit because the stopper pin 30 cannot move beyond the edge 28a of the stopper hole 28. That is, the stopper pin 30 and the stopper hole 28 define the adjustment position of the charging panel 12.

In the present embodiment, the charging device 10 is described as having the magnetic attraction wireless charging function as an example, but the scope of the present invention is not limited thereto. In such an embodiment, the charging device 10 can both stably support the charged equipment by means of the magnetic attraction force and allow the user to adjust the use posture of the charging device 10 according to the use habit of the user. Features related to the magnetically-attracted wireless charging function will be described in detail later.

Referring now to fig. 3, an exploded view of the charging device 10 is shown. As shown, the cradle 14 of the charging device 10 includes a base 16 and a hollow pole 18. The base 16 is mainly used to house the charge control circuit. This eliminates the need for a bulky charge control circuit to be disposed in the raised charging panel 12 to avoid affecting the angular adjustability of the charging panel 12 due to excessive weight of the charging panel itself. A weight may be provided in the base 16 to keep the center of gravity of the charging device 10 as low as possible to stably maintain it on a working plane, thereby preventing rollover, toppling, etc. when adjusting the angle of the charging panel 12. The projection of the charging panel 12 on the working plane of the charging device 10 is at least partially, preferably completely, covered by the base 16, which likewise increases the structural stability of the charging device 10. A hollow stem 18 extends from one end of the base 16 and is angled with respect to the base 16, preferably perpendicular to the base 16. The hollow rod 18 is mainly used to accommodate a cable 20 connected to the charge control circuit, and thus has a cavity that allows the cable 20 to pass through.

The charging panel 12 of the charging device 10 includes a face shell 22 and a bottom shell 24. The face case 22 is configured to be contactable with a device to be charged. In the embodiment where the charging device 10 has the magnetic wireless charging function, the face case 22 is driven by the magnetic attraction force when the charging device 10 approaches to attract the device to be charged, and can hold the device to be charged firmly while charging the device to be charged by the contact therebetween. The bottom case 24 is used to connect the charging panel 12 to the stand 14. To this end, bottom shell 24 is configured in a tapered shape that tapers to a narrower end, such as the generally conical housing shown in the figures. The bottom shell 24 is coupled with the bracket 14 by its narrowed end, and thus can function to keep the cable 20, which passes through the hollow rod 18 of the bracket 14, continuously folded to prevent the harness from being scattered to be accidentally damaged when the relative adjustment movement of the charging panel 12 occurs. The bottom case 24 is also coupled with the face case 22 through an end opposite to the narrowed end, so that the bottom case 24 is closed with the face case 22 and forms the receiving space S therein.

The charging panel 12 further includes an intermediate member 26, and the intermediate member 26 is disposed in the accommodating space S between the bottom case 24 and the face case 22, and is fixedly connected to the bottom case 24. A stopper hole 28 is formed in the intermediate member 26. Correspondingly, the stopper pin 30 is provided at an end of the hollow rod 18 farther from the base 16, i.e., an end of the hollow rod 18 coupled to the bottom case 24. As mentioned above, the hollow shaft 18 extends from one end of the base 16, and the limit pin 30 is disposed at the other end of the hollow shaft 18 opposite to the base 16. Further reference is made to fig. 4, which shows an enlarged view of the end of the hollow rod 18 provided with the arresting pin 30.

As can be seen more clearly in FIG. 4, the end of the hollow rod 18 has a spherical formation 29, with a stop pin 30 extending from the spherical formation 29. It will be appreciated that the spherical structure 29 has rotational symmetry and thus facilitates angular adjustment of the charging panel 12 relative to the cradle 14 in a rotational motion. The spherical structure 29 is also hollow, and the cable 20 passing through the hollow rod 18 can change the extending direction in a relatively gentle transition inside the spherical structure 29 without damaging the cable 20. Preferably, the limit pin 30 extends in a direction parallel to the central axis of the hollow rod 18 at the end of the spherical structure 29, which allows a better correspondence of the movement of the limit pin 30 with respect to the limit hole 28 and the angular adjustment of the charging panel 12 with respect to the cradle 14. In the assembled state of the charging device 10, the stopper pin 30 extends into the bottom case 24 and further into the stopper hole 28 of the intermediate member 26. In addition, the spherical structure 29 may also be partially or completely received within the bottom shell 24.

Further reference is made to fig. 5 to describe the engagement of the restraint pin 30 with the restraint hole 28. It was mentioned above that the charging panel 12 has an adjustment position with respect to the bracket 14 within certain limits, in particular an extreme adjustment position, which is in fact the position where the limit pin 30 is in contact with the edge 28a of the limit hole 28. Therefore, the overall adjustable range of the charging panel 12 before reaching the limit adjustment position is related to the size of the cross-sectional area of the stopper hole 28, and of course, the ratio of the cross-sectional area of the stopper pin 30 to the cross-sectional area of the stopper hole 28.

In a preferred embodiment of the present invention, the stopper hole 28 is formed to have a straight edge 28a. This defines the extreme adjustment position of the charging panel 12 in the direction perpendicular to the straight edge 28a. For example, in the illustrated embodiment, the stopper hole 28 is formed in a quadrangular shape having four straight edges 28a, and thus the stopper hole 28 defines an extreme adjustment position of the charging panel 12 in a direction perpendicular to each of the straight edges 28a. Further, the stopper hole 28 is formed in a parallelogram shape, that is, each two opposing straight edges 28a are parallel to each other, which results in directions perpendicular to each of the two opposing straight edges 28a also being parallel to each other. In other words, such a limit hole 28 collectively defines the limit adjustment positions of the charging panel 12 in two intersecting directions. When the stopper hole 28 is configured as a rectangular quadrangle, it defines the extreme adjustment positions of the charging panel 12 in two orthogonal directions.

For example, referring to fig. 6 and 7, the adjustable range of the charging panel 12 in the left-right direction with respect to the stand 14 is shown. Similarly, fig. 8 shows the adjustable range of the charging panel 12 in the up-down direction with respect to the stand 14. Therefore, the charging panel 12 according to an embodiment of the present invention has the limit adjustment positions in two orthogonal directions, the left-right direction and the up-down direction. The terms "upper", "lower", "left", "right" and the related directions are explained herein based on the charging device 10 being used on a horizontal work plane.

Alternatively, the restraint apertures 28 may be configured as a rectangular quadrilateral having substantially equal length and width, i.e., a square. It will be appreciated that in this case, the limiting hole 28 defines the limit adjustment position of the charging panel 12 such that its adjustable range in two orthogonal directions is substantially the same.

The above limit adjustment position forms a definition of the adjustment position of the charging panel 12.

With continued reference to fig. 5, a restraint aperture 28 is disposed in a predetermined location in the intermediate member 26. Preferably, the restraint aperture 28 is disposed in the center of the intermediate member 26. This allows the stopper pin 30 extending from the spherical structure 29 to maintain the original extending direction without being bent, and thus enables to maintain a better consistency between the movement of the stopper pin 30 with respect to the stopper hole 28 and the angular adjustment of the charging panel 12 with respect to the cradle 14.

Preferably, the center of the intermediate member 26 is formed with more than one stopper hole 28. Correspondingly, more than one limit pin 30 is provided at the spherical structure 29 at the end of the hollow rod 18 of the bracket 14. Accordingly, multiple points of contact may be made between the more than one stopper hole 28 and the more than one stopper pin 30, so that the charging panel 12 is more firmly held in the adjusted position with respect to the bracket 14. In the illustrated embodiment, the number of the limiting holes 28/limiting pins 30 is two, but the number of the limiting holes 28/limiting pins 30 may be more than two. Alternatively, the number of the limiting holes 28/limiting pins 30 may be less than two, and accordingly the size of the limiting holes 28 is designed to provide a corresponding adjustment position for the charging panel 12.

To improve the durability of the intermediate member 26, it is preferably made of a material having a relatively high hardness. For example, the intermediate member 26 may be made of a galvanized sheet. This can improve the structural strength of the entire charging panel 12 while reducing the manufacturing cost.

Turning now to fig. 3, to implement the magnetic attraction wireless charging function, the charging panel 12 of the charging device 10 of the present embodiment further includes a coil unit 32 and a magnet unit 34. The coil unit 32 is used for supplying power to the charged device in a wireless manner, for example, by electromagnetic induction, and the function and structure thereof are substantially identical to those of the existing coil unit 32, and will not be described herein again. The magnet unit 34 has a substantially ring shape and is disposed around the outer periphery of the coil unit 32. The magnet unit 34 can keep the charged device adapted to the magnetic charger by the magnetic attraction force, so that the charging device 10 has a simple structure and is reliably connected. In order to prevent the angular adjustment of the charging panel 12 relative to the bracket 14 from affecting the charging state, the coil unit 32 and the magnet unit 34 are both disposed between the intermediate member 26 and the panel case 22 in the accommodating space S. Preferably, the coil unit 32 is arranged at a distance from the intermediate piece 26.

The charging device 10 further includes a damping member 36. The damper 36 is disposed between the bottom case 24 and the intermediate member 26 in the accommodation space S, and fills the space there. In a preferred embodiment, the damping member 36 has a spherical recess (not shown) on the side opposite the intermediate member 26, into which spherical recess the spherical formation 29 at the end of the hollow rod 18 of the holder 14 at least partially protrudes, into the damping member 36. When the charging panel 12 is angularly adjusted relative to the cradle 14, the spherical structure 29 at the end of the hollow rod 18 comes into contact with the spherical recess of the damper 36, thus creating a frictional force therebetween.

Optionally, the shape of the damping member 36 is also adapted to the shape of the bottom case 24, and thus can contact the bottom case 24 when the charging panel 12 is angularly adjusted with respect to the bracket 14. For example, the illustrated damping member 36 also has a tapered shape with a tapered end. When the charging panel 12 is angularly adjusted with respect to the bracket 14, the intermediate member 26 fixed to the bottom case 24 is relatively moved with respect to the end of the hollow rod 18 at the spherical structure 29, and the damper member 36 is pressed by the spherical structure 29 to be in contact with the bottom case 24 and provide a frictional force.

The friction between the bracket 14 and the damper 36 (and optionally between the damper 36 and the bottom shell 24) provides resistance to the movement described above, but is insufficient to counteract the driving force that drives the angular adjustment of the charging panel 12 relative to the bracket 14. In this way, the friction provided by the damper 36 helps to maintain the bottom shell 24 in a balanced position relative to the hollow stem 18, thereby precisely positioning the charging panel 12 in the user-desired adjustment position relative to the cradle 14. And damping piece 36 still provides the damping sense in this process, avoids charging panel 12 too nimble and difficult location, has consequently promoted user experience.

To provide suitable frictional forces, the damping member 36 is made of a flexible material. For example, the damping member 36 is made of silicone rubber having a shore a hardness of about 45 degrees. The intermediate member 26 has a greater stiffness than the damping member 36. For example, as previously described, the intermediate member 26 may be made of galvanized sheet. Accordingly, the damping member 36 may be compressed to be deformed to further provide a frictional force by contact with the spherical structure 29 or the bottom case 24.

The charging device 10 also includes a connector 38 (see fig. 5) for securing the intermediate member 26 to the bottom case 24. In the present embodiment, the connecting member 38 penetrates the intermediate member 26 and the damper member 36, and connects the intermediate member 26, the damper member 36 to the bottom case 24 in order according to the positional relationship described above. The connecting member 38 may be a bolt. Correspondingly, the bottom shell 24 may be provided with an internal thread. In the illustrated embodiment, the bottom case 24 is provided with an integrated fixing post having an inner circumferential surface formed with an internal thread. The connecting member 38 (bolt) is screwed with the fixing post of the bottom case 24, thereby securely connecting the intermediate member 26, the damper 36 to the bottom case 24.

Preferably, at least one of the damping member 36, the intermediate member 26, the magnet unit 34 is provided with a notch 40 for the cable 20 in the hollow rod 18 to pass through. Thereby, it is possible to provide sufficient space for the cable 20 connected to the coil unit 32 to prevent the cable 20 from being accidentally damaged by being crushed when the charging panel 12 is angularly adjusted with respect to the bracket 14.

According to the above description, the charging device of the present invention can adjust the angle of the charging panel relative to the bracket within the predetermined adjustable range, and can improve the operability by the variable use posture, and also avoid the influence of the movable component provided for the angle adjustment on other components, especially the internal cable, thereby prolonging the service life.

Variants

In the above embodiment, the charging device 10 is described as being implemented with a magnetic wireless charging function, but in a modified embodiment, the charging device may not have a magnetic wireless charging function.

For example, the charging panel may provide power to a device to be charged that it holds by wired means. That is, instead of or in addition to the coil unit, the charging panel may have a cable capable of transmitting power to be supplied with power by accessing the charging port to be charged through the cable connection.

For example, the charging panel may hold the charged device by physical force other than magnetic attraction force. That is, the charging panel may have a clip or a buckle capable of clamping or chucking the device to be charged, instead of or in addition to the magnet unit, to keep it connected to the charging panel by a holding force of the clip or the buckle to the device to be charged.

According to the charging apparatus of this modified embodiment, more types of devices to be charged can be supplied with power, and thus, it has wide applicability.
