In accordance with the purposes of this disclosure, as embodied and broadly described herein, in certain aspects, this disclosure relates to a wireless charging system, such as but not limited to a wireless charging system for an electric vehicle.

Referring to fig. 1 and 2, fig. 1 is a general schematic diagram of a wireless charging system 100 installed on an electric vehicle according to an embodiment of the present invention, and fig. 2 is an exploded view of the wireless charging system 100 installed on the electric vehicle according to an embodiment of the present invention. As shown in fig. 1 and fig. 2, the wireless charging system 100 of the present embodiment includes a charging transmitting device 110, a tiltable panel 120, a rotating shaft 130 and a bracket assembly 140, wherein the support assembly 140 is disposed on a support surface 150 (not shown in fig. 1 and 2), the support surface 150 may be a floor or a near-floor slab, the tiltable panel 120 is rotatably disposed on the bracket assembly 140 via the rotating shaft 130, the charging and transmitting device 110 is mounted at one end (e.g. a first end) of the tiltable panel 120, in the present embodiment, the rotatable tilting panel 120 means that the rotating shaft 130 pivots the tilting panel 120 to the bracket assembly 140, and the pivoted position of the rotating shaft 130 on the tiltable panel 120 is located at a substantially middle position of the tiltable panel 120, so that when one end of the tiltable panel 120 is pressed downwards by a force, the other end can tilt upwards relative to the bearing surface 150 or the bracket assembly 140. Specifically, in the present embodiment, the charging emitter 110 is disposed at one end of the tiltable panel 120, and when the other end (for example, the second end) of the tiltable panel 120 away from the charging emitter 110 is pressed to approach the supporting surface 150 (for example, turned downward), the end (the first end) of the tiltable panel 120 where the charging emitter 110 is disposed is tilted relative to the supporting surface 150, so that the charging emitter 110 is upwardly away from the supporting surface 150. Generally, the charging and transmitting device 110 is installed on the bottom surface of the tilting panel 120, and a protective coating may be further disposed on the charging and transmitting device 110 to perform the functions of dust prevention and water prevention. In one embodiment, the pivot position of the shaft 130 on the tiltable panel 120 is located at the middle of the tiltable panel 120 and is biased to the second end.

Referring to fig. 3, fig. 3 is a bottom schematic view of a tiltable panel according to an embodiment of the present invention. In this embodiment, the tiltable panel 120 further includes a pivot portion 121, the pivot 130 connects the tiltable panel 120 to the bracket assembly 140 through the pivot portion 121, specifically, the pivot portion 121 has a through hole along the axial direction, and the pivot 130 passes through the through hole to set the tiltable panel 120 on the bracket assembly 140. The pivoting portion 121 may be disposed at the bottom of the tiltable panel 120, and specifically may be located approximately such that the length from the first end a to the pivoting portion 121 is not less than the length from the second end B to the pivoting portion 121, so that the tiltable panel 120 is in a non-tilting state when the charging system is not in use; for example, since the first end a is installed with the charging and transmitting device 110, the weight of the first end a is usually greater than that of the second end B, when the external pressure applied to the second end disappears, the first end a automatically returns to the original position, that is, the tiltable panel 120 normally maintains the non-tilted state (e.g., parallel to the supporting surface 150). In this embodiment, a supporting member (not shown) may also be disposed on the bracket assembly 140 for supporting the first end a of the tiltable panel 120, so that the tiltable panel 120 is in a state of being horizontally flush with the top of the bracket assembly 140 as shown in fig. 4A when not in use. Of course, the invention is not limited thereto.

Referring to fig. 3, in the present embodiment, the charging and transmitting device 110 further includes a transmitting unit 111 and a power conversion device 112, the transmitting unit 111 is electrically connected to the power conversion device 112, wherein the transmitting unit 111 has a magnetic induction coil (i.e., a transmitting coil) for wireless charging, and when the tiltable panel 120 is parallel to the supporting surface 150 (i.e., the tiltable panel 120 is not tilted), the transmitting coil is parallel to the supporting surface 150; in addition, in the present embodiment, in order to reduce the weight of the tiltable panel 120, the power conversion apparatus 112 is selectively fixed on the bracket assembly 140.

More specifically, as described above, the supporting surface 150 may be, for example, a ground or a flat plate near the ground, the bracket assembly 140 is disposed on the supporting surface 150, and the tiltable panel 120 is disposed on the bracket assembly 140, that is, in this embodiment, when the electric vehicle needs to be charged, the electric vehicle needs to be parked on the bracket assembly 140 and located above the tiltable panel 120, so that when one end (first end) of the tiltable panel 120, at which the charging transmitting device 110 is disposed, is tilted relative to the supporting surface 150, the charging transmitting device 110 can be closer to a charging receiving device (a built-in receiving coil) disposed on the electric vehicle, so as to improve the wireless charging efficiency.

For example, an electric vehicle, such as an electric motorcycle (motorbike), may adopt a parking mode in which a foot stand is erected to support a vehicle body so that a front wheel is kept on the ground but a rear wheel is suspended, and the whole electric vehicle is inclined in a longitudinal direction (front-rear direction) with respect to a carrying surface 150. And the bottom of the electric vehicle can be provided with a receiving coil for wireless charging, and the electric vehicle can be inclined relative to the bearing surface 150 in the longitudinal direction when being parked, and correspondingly, the receiving coil can also be inclined relative to the bearing surface 150. In order to match the inclination angle of the electric vehicle when the electric vehicle is parked, the transmitting coil of the wireless charging system is better attached to the receiving coil of the electric vehicle, and the transmitting coil and the receiving coil are relatively parallel to each other, in an embodiment, the transmitting coil inside the charging transmitting device 110 is set to form a certain inclination angle after the tilt of the tiltable panel 120, that is, when the tiltable panel 120 tilts, the whole tiltable panel 120 is inclined relative to the bearing surface 150 in the longitudinal direction, and correspondingly, the transmitting coil is also inclined relative to the bearing surface 150 in the longitudinal direction, so that the transmitting coil and the receiving coil can be relatively parallel to each other. That is, after the end a of the tilting panel 120 tilts, the charging transmitter 110 is closer to the charging receiver at the bottom of the electric vehicle, and the transmitting coil and the receiving coil can be relatively parallel to each other, thereby further improving the wireless charging efficiency.

For example, the electric vehicle can also adopt the mode of side berthing to park, adopts the heel brace of electric vehicle one side to make the electric vehicle park on the parking stall promptly, so makes the electric vehicle always present the tilt state of certain degree when parking. In order to match the inclination angle of the electric vehicle when the electric vehicle is parked, so that the transmitting coil of the wireless charging system is better attached to the receiving coil of the electric vehicle, and the transmitting coil and the receiving coil are relatively parallel to each other, in an embodiment of the invention, the transmitting coil inside the charging transmitting device 110 is provided with a certain inclination angle, and when the tiltable panel 120 is tilted, the transmitting coil is tilted relative to the bearing surface 150, so that the transmitting coil and the receiving coil can be relatively parallel to each other. Further, different electric vehicles may have different inclination states, and therefore the inclination angles required to be adapted to the different electric vehicles are correspondingly different, in order to meet the requirement, in the embodiment, an internal compensation inclination angle capable of automatically adapting and adjusting the inclination angle is provided in the charging and transmitting device 110, that is, when the tilting panel 120 tilts up, the transmitting coil adjusts the inclination angle thereof according to the inclination state of the receiving coil, and inclines relative to the horizontal plane, so as to be parallel to the receiving coil, thereby further improving the wireless charging efficiency.

In addition, since the tilting panel 120 is also tilted when tilting, the charging transmitter 110 disposed at one end of the tilting panel 120 is tilted accordingly, and similarly, in order to keep the parallel alignment between the charging transmitter 110 and the receiver on the electric vehicle, an inclination angle can be preset on the tilting panel 120 for the charging transmitter 110, and the preset inclination angle is generally equal to an included angle between the tilting panel 120 and a horizontal plane.

Referring to fig. 3, in this embodiment, the charging transmitter 110 may further include a temperature reduction unit 113 and a position adjustment unit 114, where the temperature reduction unit 113 is disposed corresponding to the transmitter and/or the power converter, and is, for example, a fan for reducing the temperature of the wireless charging device; the position adjusting unit 114 connects the main body of the charging transmitter and the tiltable panel 120, and is used for manually adjusting the position of the charging transmitter on the tiltable panel to improve the charging efficiency when the matching signal between the receiving coil and the transmitting coil is poor.

The upper plate 141 is provided with an opening 143, the tiltable panel 120 is rotatably provided at the opening 143 along an axial position, and the tiltable panel 120 may be substantially at the same horizontal plane as the upper plate 141 in a static state when not in use. As shown in fig. 4B, when the second end B of the tiltable panel 120 is pressed downward by a force, the tiltable panel can rotate in the cavity toward the supporting surface 150, so that the first end a tilts relative to the supporting surface 150. For example, when the electric vehicle is pulled to a proper position of the upper plate 141 and parked vertically by the foot stand, the front wheel of the electric vehicle presses the second end B, so that the second end B sinks and the first end a tilts, and the first end a is close to the charge receiving device 160 disposed at the bottom of the electric vehicle.

Of course, the invention is not limited thereto, and in other embodiments, the first limiting device 145 may also be disposed on the tiltable panel 120, and may also function to limit the wheel of the electric vehicle.

Similarly, to better define the parking state of the electric vehicle, a second limiting device 146 may be additionally disposed on the bracket assembly 140 for limiting the parking position of another wheel (e.g., a rear wheel) of the electric vehicle on the bracket assembly 140. As shown in fig. 5C, the second position-limiting device 146 may be designed in the form of a groove, and the invention is not limited thereto. The first position-limiting device 145 or the second position-limiting device 146 can be used for positioning, and after a user pulls the electric vehicle to the upper plate, the user can confirm that the electric vehicle reaches the positioning by contacting the first position-limiting device 145 or the second position-limiting device 146 through the front wheels or the rear wheels.
