According to an embodiment of the invention, the charging device is used for forming a charging loop with the electronic device. The charging device comprises a base and a first wireless charging end. The first wireless charging end is arranged in the base, wherein the first wireless charging end and the base can move relatively.

According to an embodiment of the invention, a charging system includes a base, an electronic device, a first wireless charging terminal and a second wireless charging terminal. The electronic device is disposed adjacent to the base. The first wireless charging end is arranged in the base. The second wireless charging end is arranged in the electronic device, and the first wireless charging end and the base can move relatively.

Detailed Description

Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Certain terms are used throughout the description and following claims to refer to particular components. Those skilled in the art will appreciate that electronic device manufacturers may refer to a component by different names. It is not intended to distinguish between components that differ in function but not name. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to …".

Directional terms mentioned herein, such as: "upper", "lower", "front", "rear", "left", "right", etc., are merely directions with reference to the drawings. Thus, the directional terminology is used for purposes of illustration and is not intended to be limiting of the invention. In the drawings, the various figures illustrate the general features of methods, structures and/or materials used in certain embodiments. However, these drawings should not be construed as defining or limiting the scope or nature of what is covered by these embodiments. For example, the relative dimensions, thicknesses, and locations of various layers, regions, and/or structures may be reduced or exaggerated for clarity.

The presence of one structure (or layer, element, substrate) on/over another structure (or layer, element, substrate) as described herein may refer to two structures being adjacent and directly connected, or may refer to two structures being adjacent and not directly connected. Indirect connection refers to having at least one intervening structure (or intervening layers, intervening elements, intervening substrates, intervening spaces) between two structures, the lower surface of one structure being adjacent to or directly connected to the upper surface of the intervening structure, and the upper surface of the other structure being adjacent to or directly connected to the lower surface of the intervening structure. The intermediate structure may be a single-layer or multi-layer solid structure or a non-solid structure, and is not limited thereto. In the present invention, when a structure is disposed "on" another structure, it may mean that the structure is "directly" on the other structure, or that the structure is "indirectly" on the other structure, that is, at least one structure is further interposed between the structure and the other structure.

The terms "about," "equal," or "identical," "substantially," or "substantially" are generally interpreted as being within 20% of a given value or range, or as being within 10%, 5%, 3%, 2%, 1%, or 0.5% of the given value or range. Furthermore, the terms "range from a first value to a second value," and "range between a first value and a second value," mean that the range includes the first value, the second value, and other values therebetween.

The use of ordinal numbers such as "first," "second," and the like in the description and in the claims is used for modifying an element, and is not by itself intended to exclude the presence of any preceding ordinal number(s) or order(s) of a certain element or another element or order(s) of manufacture, and the use of such ordinal numbers merely serves to distinguish one element having a certain name from another element having a same name. The same words may not be used in the claims and the specification, whereby a first element in the description may be a second element in the claims.

In some embodiments of the invention, terms such as "connected," "interconnected," and the like, with respect to joined, connected, and the like, may refer to two structures as being in direct contact, or may refer to two structures as being not in direct contact, unless otherwise specified, with other structures disposed between the two structures. And the term coupled, connected, may also include situations where both structures are movable, or where both structures are fixed. Furthermore, the term "coupled" includes any direct or indirect electrical connection. In addition, the term "coupled" includes signal communication means by which two elements or devices may directly or indirectly receive and/or transmit wireless signals.

The electrical connection or coupling described in the present invention may refer to a direct connection or an indirect connection, in which case the terminals of the elements of the two circuits are directly connected or connected with each other by a conductor segment, and in which case the terminals of the elements of the two circuits have a switch, a diode, a capacitor, an inductor, a resistor, other suitable elements, or a combination of the above elements, but is not limited thereto.

In the present invention, the thickness, length and width may be measured by an optical microscope (Optical Microscope, OM), and the thickness or width may be measured by a cross-sectional image of an electron microscope, but is not limited thereto. In addition, any two values or directions used for comparison may have some error. Furthermore, the terms "a given range of values from a first value to a second value," "a given range falling within a range of values from the first value to the second value," or "a given range between the first value and the second value," mean that the given range includes the first value, the second value, and other values therebetween. If the first direction is perpendicular to the second direction, the angle between the first direction and the second direction may be between 80 degrees and 100 degrees; if the first direction is parallel to the second direction, the angle between the first direction and the second direction may be between 0 degrees and 10 degrees.

It is to be understood that the following exemplary embodiments may be substituted, rearranged, and mixed for the features of several different embodiments without departing from the spirit of the invention to accomplish other embodiments. Features of the embodiments can be mixed and matched at will without departing from the spirit of the invention or conflicting.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be appreciated that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present invention and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Fig. 1A, 2A, 3A and 4 are schematic diagrams of a charging system according to various embodiments of the present invention before the charging device accommodates an electronic device. Fig. 1B is a schematic diagram of the charging system of fig. 1A after the charging device accommodates an electronic device. FIG. 1C is a schematic cross-sectional view of the section line I-I' in FIG. 1B.

Fig. 2B is a schematic cross-sectional view of the charging device in the charging system of fig. 2A after receiving an electronic device. Fig. 3B is a schematic diagram illustrating a stress direction of the second wireless charging terminal when the electronic device is received.

Referring to fig. 1A to 1C, the charging system 1 may include an electronic device 11 and a charging device 2, and the electronic device 11 may be accommodated in the charging device 2. The charging device 2 may include a base 10 and a first wireless charging terminal 12, but the present invention is not limited thereto. The first wireless charging terminal 12 may be disposed in the base 10, so the first wireless charging terminal 12 may not be shown on the external appearance of the base 10. In one embodiment, the base 10 may comprise a transparent material (e.g., glass or acrylic), and the first wireless charging terminal 12 may be displayed from the appearance of the base 10. The first wireless charging end 12 of the charging device 2 and the base 10 can move relatively, but the invention is not limited thereto. In other embodiments, the relative position of the first wireless charging terminal 12 and the base 10 is fixed, for example. The electronic device 11 may include a second wireless charging terminal 13, where the second wireless charging terminal 13 is disposed in the electronic device 11, and a relative position of the second wireless charging terminal 13 and the electronic device 11 is fixed, for example, but the invention is not limited thereto. In other embodiments, the second wireless charging terminal 13 and the electronic device 11 can move relatively.

In detail, the base 10 of the charging device 2 can be used for carrying or accommodating the electronic device 11, and the first wireless charging terminal 12 in the base 10 and the second wireless charging terminal 13 in the electronic device 11 can form a charging loop, so as to realize wireless charging. For example, the first wireless charging terminal 12 may be a power transmitting terminal, and the second wireless charging terminal 13 may be a power receiving terminal. Under this architecture, the charging device 2 can wirelessly charge the electronic device 11. Alternatively, the first wireless charging terminal 12 may be a power receiving terminal, and the second wireless charging terminal 13 may be a power transmitting terminal. Under this architecture, the electronic device 11 can wirelessly charge the charging device 2.

In some embodiments, as shown in fig. 1A, when the electronic device 11 is a movement detection device, the charging device 2 may be a movable charging device, such as a mobile cart or the like. When the first wireless charging terminal 12 is a power transmitting terminal, the charging device 2 can charge a component or a device (such as the electronic device 11) accommodated therein. On the other hand, when the first wireless charging terminal 12 is a power receiving terminal, the charging device 2 may be used as a storage battery, and the components or devices (e.g. the electronic device 11) accommodated therein may charge the charging device 2, and the power stored in the charging device 2 may be transferred to other components or devices to be charged, such as other components (not shown) disposed on the charging device 2 (e.g. the mobile cart) in a wired or wireless manner.

The specific shape of the base 10 is not limited. Taking fig. 1A as an example, the base 10 may include a supporting portion 100, a limiting portion 101, a limiting portion 102, a limiting portion 103, and a limiting portion 104. The stopper 101, the stopper 102, the stopper 103, and the stopper 104 are provided on the support 100 and connected to the support 100. The limiting portion 102 and the limiting portion 103 are disposed opposite to each other in the direction D1 and can be used to limit the displacement of the component or the device (such as the electronic device 11) received in the base 10 in the direction D1. The limiting portion 101 and the limiting portion 104 are disposed between the limiting portion 102 and the limiting portion 103 and are opposite to each other in the direction D2, and the limiting portion 101 and the limiting portion 104 can be used to limit the displacement of the component or the device (such as the electronic device 11) received in the base 10 in the direction D2.

For example, the support portion 100 may comprise a plate, and the limiting portions 101, 102, 103, and 104 may comprise slots, baffles, or other suitable limiting/securing elements. It should be understood that the design parameters of the base 10 (e.g., number of components, shape, size, relative configuration, and/or materials, etc.) may be changed as desired, and are not limited to those shown in fig. 1A-1C. For example, the base 10 may omit at least one of the limiting portion 101 and the limiting portion 104. Alternatively, the base 10 may omit the stopper 102 and the stopper 103. Alternatively, the stopper 101 may be equal in height to the stopper 104 in the direction D3. Further, the shape and/or size of the base 10 may be varied as desired. In some embodiments, the supporting portion 100, the limiting portion 101, the limiting portion 102, the limiting portion 103, and the limiting portion 104 may be made of a single material and may be an integrated structure. In other embodiments, the support portion 100, the limiting portion 101, the limiting portion 102, the limiting portion 103, and the limiting portion 104 may be formed of multiple materials and may be secured together by mechanical members, adhesives, or other securing means.

In some embodiments, the base 10 may have a space SP, and the first wireless charging terminal 12 is disposed in the space SP. The space SP is a cavity inside the base 10 for accommodating the first wireless charging terminal 12. The size of the space SP (e.g., the width in the direction D1, the direction D2, and/or the direction D3) may be designed to be larger than the size of the first wireless charging terminal 12, so as to improve the convenience of storage and/or improve the flexibility of the wireless charging terminal setting position.

Although not shown, in other embodiments, a mobile cart may be used as the base 10, and the first wireless charging end 12 may be disposed within the mobile cart (i.e., the base 10). When the first wireless charging terminal 12 is a power transmitting terminal, the mobile cart (i.e. the base 10) can charge the components or devices (e.g. the electronic device 11) accommodated therein. On the other hand, when the first wireless charging terminal 12 is a power receiving terminal, the mobile cart (i.e. the base 10) can be used as a storage battery, and the components or devices (e.g. the electronic device 11) accommodated therein can charge the mobile cart (i.e. the base 10), and the power stored in the mobile cart (i.e. the base 10) can be transmitted to other components or devices to be charged, such as other components (not shown) disposed on the mobile cart (i.e. the base 10) through a wired or wireless manner.

The kind or use of the mobile cart is not limited. For example, the mobile cart may be a work cart, a storage cart, a cargo cart, a folding cart, a flatbed cart, or other mobile carrier. In addition, the mobile cart may also be used to transport medical instruments, electronics, food, cargo, or other components or devices.

The type and shape of the electronic device 11 is not limited. For example, the electronic device 11 may include a display device, a backlight device, an antenna device, a detection device, a stitching device, or any device requiring charging. In addition, the electronic device 11 may be a bendable or flexible electronic device. The display device may be a non-self-luminous type display device or a self-luminous type display device. The display device may include, for example, liquid crystals (QDs), light emitting diodes (leds), fluorescence (fluorescence), phosphorescence (phosphorescence), quantum Dots (QDs), other suitable display media, or combinations of the foregoing. The antenna device may be a liquid crystal type antenna device or a non-liquid crystal type antenna device. The detection device may be a detection device for sensing capacitance, light (such as visible light or X-ray), heat energy or ultrasonic wave, but is not limited thereto. In some embodiments, the electronic device 11 may include electronic components. The electronic components may include passive components and active components such as capacitors, resistors, inductors, diodes, transistors, and the like. The diode may comprise a light emitting diode or a photodiode. The light emitting diode may include, for example, an organic light emitting diode (organic light emitting diode, OLED), a sub-millimeter light emitting diode (mini LED), a micro LED, or a quantum dot LED (but is not limited thereto. The splicing device may be, for example, a display splicing device, a detection splicing device or an antenna splicing device, but is not limited thereto.

It should be noted that the electronic device 11 may be any of the above arrangements, but is not limited thereto. In addition, the shape of the electronic device 11 may be rectangular, circular, polygonal, a shape with curved edges, or other suitable shapes. The electronic device 11 may have a driving system, a control system, a light source system, and other peripheral systems to support a display apparatus, an antenna device, a wearable device (including augmented reality or virtual reality, for example), an in-vehicle device (including an automobile windshield, for example), a mosaic device, or the like.

The first wireless charging terminal 12 and the second wireless charging terminal 13 respectively include a first coil 120 and a second coil 130, and the first coil 120 and the second coil 130 utilize electromagnetic induction of faraday's law to generate an induced current, so as to transfer energy from a power transmitting terminal to a power receiving terminal, thereby realizing wireless charging.

In some embodiments, as shown in fig. 1A and 1C, the first wireless charging terminal 12 and the second wireless charging terminal 13 may further include a magnetic body 121 (referred to as a second magnetic body in the claims) and a magnetic body 131 (referred to as a fourth magnetic body in the claims), respectively, wherein the magnetic body 121 may be disposed on the back side of the first coil 120, and the magnetic body 131 may be disposed on the back side of the second coil 130, such that when the first wireless charging terminal 12 and the second wireless charging terminal 13 are disposed adjacent to each other, the first coil 120 and the second coil 130 are located between the magnetic body 121 and the magnetic body 131 (see fig. 1C). In fig. 1A and 1C, in order to clearly show the relative arrangement relationship of the first coil 120 and the magnetic body 121 and the relative arrangement relationship of the second coil 130 and the magnetic body 131, the magnetic body 121 is shown to be slightly smaller than the first coil 120 and the magnetic body 131 is shown to be slightly smaller than the second coil 130, but it should be understood that the relative sizes or the relative arrangement relationship of the coils and the corresponding magnetic bodies may be changed as required, and are not limited to those shown in fig. 1A and 1C.

The magnetic body 121 and the magnetic body 131 may have different magnetic properties to facilitate positioning and/or coupling of the first wireless charging terminal 12 and the second wireless charging terminal 13. For example, one of the magnetic body 121 and the magnetic body 131 may include an N-type magnet, and the other of the magnetic body 121 and the magnetic body 131 may include an S-type magnet. The second wireless charging terminal 13 and the first wireless charging terminal 12 are attracted to each other based on the principle of magnetic opposite attraction, so as to reduce the probability of separating or shifting the first wireless charging terminal 12 and the second wireless charging terminal 13 from each other when the charging device 2 is moved or vibrated by an external force, thereby being beneficial to improving the charging efficiency.

In the case that at least one of the wireless charging terminals is movable (e.g., the position of the first wireless charging terminal 12 relative to the base 10 is variable), if the electronic device 11 is placed in the base 10, the initial positions of the first wireless charging terminal 12 and the second wireless charging terminal 13 may not be aligned, and at this time, the movable wireless charging terminal (e.g., the first wireless charging terminal 12) may be moved towards the fixed wireless charging terminal by the magnetic force of the other fixed wireless charging terminal (e.g., the second wireless charging terminal 13 is fixed relative to the electronic device 11) to achieve automatic alignment. According to the above-mentioned design that the position of the first wireless charging end 12 is changeable (movable), no matter how the second wireless charging end 13 is disposed at any position of the electronic device 11, the first wireless charging end 12 and the second wireless charging end 13 can be automatically aligned, so that the probability that the first wireless charging end 12 and the second wireless charging end 13 are separated from each other or are aligned and offset due to movement or vibration of the electronic device 11 and the base 10 caused by external force can be reduced, and further the charging efficiency can be improved. In other words, by the design that the position of the first wireless charging terminal 12 is changeable (movable), the setting position of the second wireless charging terminal 13 relative to the electronic device 11 can be more flexible. Further, since the position of the first wireless charging terminal 12 is variable (movable), the convenience of storage can be improved without considering the directivity problem when the electronic device 11 is put into the base 10. For example, the bottom side S11 of the electronic device 11 may be disposed adjacent to the supporting portion 100, or disposed adjacent to the limiting portion 103 (i.e. the electronic device 11 of fig. 1B is rotated 90 degrees counterclockwise), or disposed away from the supporting portion 100 (i.e. the electronic device 11 of fig. 1B is rotated 180 degrees counterclockwise), or disposed adjacent to the limiting portion 102 (i.e. the electronic device 11 of fig. 1B is rotated 90 degrees clockwise).

Although the above embodiment is exemplified by the second wireless charging terminal 13 being fixed in position and the first wireless charging terminal 12 being movable (position changeable), the present invention is not limited thereto. As shown in fig. 2A and 2B, in the charging system 1A, the electronic device 11 may have a space SP, and the second wireless charging terminal 13 may be disposed in the space SP, so that the position of the second wireless charging terminal 13 relative to the electronic device 11 is movable (the position is variable) and the position of the first wireless charging terminal 12 relative to the base 10 is fixed. In other embodiments, not shown, the base of the charging device and the electronic device may have a space, the first wireless charging terminal may be disposed in the space of the base, and the second wireless charging terminal may be disposed in the space of the electronic device, so that the position of the first wireless charging terminal relative to the base is movable, and the position of the second wireless charging terminal relative to the electronic device is also movable.

Referring to fig. 3A and 3B, the main differences between the charging system 1B and the charging system 1 of fig. 1A are described below. The charging system 1B may further include a magnetic body 14 (referred to as a first magnetic body in the claims) and a magnetic body 15 (referred to as a third magnetic body in the claims), and the description of the rest will not be repeated.

As shown in fig. 3A, in an embodiment, the base 10 may have a space SP, and the first wireless charging terminal 12 is disposed in the space SP, and the second wireless charging terminal 13 is fixed relative to the electronic device 11. Therefore, when the position of the first wireless charging terminal 12 relative to the base 10 is variable, the magnetic body 14 may be disposed in the base 10 and adjacent to at least one side of the space SP. Fig. 3A schematically shows that one magnetic body 14 is provided on the lower side of the space SP. For example, the magnetic body 14 may be disposed inside or outside the supporting portion 100, but is not limited thereto. In other not shown embodiments, the charging device 2 may include a plurality of magnetic bodies 14, and the plurality of magnetic bodies 14 may be disposed along different sides of the space SP. The magnetic body 14 and the magnetic body 121 of the first wireless charging terminal 12 may have different magnetic properties. For example, one of the magnetic bodies 14 and 121 may include an N-type magnet, and the other may include an S-type magnet. When the charging device 2 moves, the magnetic body 14 can reduce the probability and/or area of movement of the first wireless charging terminal 12 in the space SP based on the principle of opposite attraction of the magnetic bodies.

As shown in fig. 3A, in an embodiment, the magnetic body 15 may be disposed in the electronic device 11 and adjacent to at least one side of the second wireless charging terminal 13. Fig. 3A schematically illustrates two magnetic bodies 15 disposed on two adjacent sides of the second wireless charging terminal 13, but not limited thereto. In other embodiments not shown, two magnetic bodies 15 may be disposed on opposite sides of the second wireless charging terminal 13, but not limited thereto. In other embodiments, the electronic device 11 may include more or less magnetic bodies 15. The magnetic body 15 and the magnetic body 121 of the first wireless charging terminal 12 may have the same magnetic properties, and the magnetic body 15 and the magnetic body 131 of the second wireless charging terminal 13 may have different magnetic properties, and thus the magnetic body 14 and the magnetic body 131 of the second wireless charging terminal 13 may have the same magnetic properties. For example, the magnetic body 15 and the magnetic body 121 of the first wireless charging terminal 12 may include N-type magnets, and the magnetic body 131 and the magnetic body 14 of the second wireless charging terminal 13 may include S-type magnets. Alternatively, the magnetic body 15 and the magnetic body 121 of the first wireless charging terminal 12 may include S-type magnets, and the magnetic body 131 and the magnetic body 14 of the second wireless charging terminal 13 may include N-type magnets.

In the case where the second wireless charging terminal 13 is fixed in position and the first wireless charging terminal 12 is movable (the position is variable), if the electronic device 11 is put into the base 10, the initial positions of the first wireless charging terminal 12 and the second wireless charging terminal 13 may not be aligned. When the first wireless charging terminal 12 includes the magnetic body 121, and the magnetic body 121 has the same magnetic property as the magnetic body 15, the first wireless charging terminal 12 is moved away from the magnetic body 15 by the repulsive force of the magnetic body 15, and the first wireless charging terminal 12 is simultaneously moved toward the second wireless charging terminal 13 by the magnetic force of the second wireless charging terminal 13 to be adsorbed together. The magnetic body 15 is utilized to push the magnetic body 121 to drive the first wireless charging end 12 to move, so that the base 10 can have a larger space SP, thereby being beneficial to further improving the convenience of storage, improving the elasticity of the wireless charging end setting position or being beneficial to storing electronic devices 11 with different sizes. Further, since the magnetic body 14 and the magnetic body 15 have different magnetic properties, the electronic device 11 can facilitate the housing of the electronic device 11 in the base 10 due to the magnetic force of the magnetic body 15 and the magnetic body 14 based on the principle of the opposite attraction of the magnetic bodies.

Although the above embodiment is exemplified by the second wireless charging terminal 13 being fixed in position and the first wireless charging terminal 12 being movable (position changeable), the present invention is not limited thereto. As shown in fig. 4, in the charging system 1C, the electronic device 11 may have a space SP, and the second wireless charging terminal 13 may be disposed in the space SP, and the position of the first wireless charging terminal 12 relative to the base 10 is fixed. Therefore, when the position of the second wireless charging terminal 13 relative to the electronic device 11 is variable, the second wireless charging terminal 13 includes the magnetic body 131, and the magnetic body 131 has the same magnetism as the magnetic body 14, so that the second wireless charging terminal 13 is moved away from the magnetic body 14 by the repulsive force of the magnetic body 14, and the second wireless charging terminal 13 is simultaneously moved toward the first wireless charging terminal 12 by the magnetic force of the first wireless charging terminal 12 to be adsorbed together.

In summary, in the embodiment of the invention, the storage convenience or the flexibility of the installation position of the wireless charging terminal can be improved by the design that at least one wireless charging terminal is movable (for example, the first wireless charging terminal and the base can relatively move). In some embodiments, the charging efficiency can also be improved by the arrangement of the magnetic body.
