Description

Wireless charging device

Technical Field

The present invention relates to a charging device, and more particularly, to a wireless charging device using wireless charging technology.

Background

Most of the electronic devices in the market have a light and thin profile for convenient carrying, and the electronic devices employ a touch screen, so that the electronic devices can be operated by inputting instructions through the touch screen, wherein the electronic devices include a smart phone, a tablet computer, a Personal Digital Assistant (PDA), or a handheld game machine (e.g., PSP, NDSL, and Gameboy series game machines). Since the electronic devices are portable, they cannot be connected to a power source at any time and must be equipped with a battery for supplying power, wherein the battery is a rechargeable battery, so that a user can charge the battery in the electronic device at a place having a power socket.

When the electric quantity of the electronic device is insufficient, a user charges a rechargeable battery of the electronic device by using a connecting wire, wherein one end of the connecting wire is inserted in the electronic device, and the other end of the connecting wire is inserted in a power supply or a mobile power supply device capable of storing electric power therein, so that the electric power provided by the power supply or the mobile power supply device can be transmitted to the electronic device by the connecting wire to charge the battery.

However, during the charging process of the battery, the length of the connecting wire is limited, so that the user is limited by the connecting wire during the charging process of the electronic device and cannot operate or carry the electronic device to move freely according to the usage habit.

In response to the trouble caused by the wired Charging method of the connection line, the development of the Charging technology has been increasing, and a Wireless Charging device capable of performing Wireless Charging (Wireless Charging) has been developed in the market. Please refer to fig. 1, which is a schematic structural diagram of a wireless charging device and an electronic device in the prior art. Fig. 1 shows a wireless charging device 11 and an electronic device 12, the wireless charging device 11 includes a body 110, a power cord 111, a driving module 112, a transmitting coil 113 and a first communication module 114, and the electronic device 12 of the prior art includes a housing 120, a receiving coil 121, a receiving module 122, a battery (not shown) and a second communication module 123.

In the wireless charging device 11 of the prior art, the power line 111 is exposed outside the main body 110 for connecting to a power supply (not shown). The driving module 112 and the transmitting coil 113 are both disposed inside the body 110, and the driving module 112 is respectively connected to the power line 111 and the transmitting coil 113, so that when the driving module 112 is driven by the power supply, a current is generated, and the current generates Magnetic Induction (Magnetic Induction) or Magnetic Resonance (Magnetic Resonance) through the transmitting coil 113, so that the transmitting coil 113 outputs corresponding power according to the Magnetic flux generated by the Magnetic Induction or Magnetic Resonance. The first communication module 114 is used for communicating with the second communication module 123 of the electronic device 12 for wireless charging. On the other hand, in the portable electronic device 12 of the prior art, the receiving coil 121 is disposed in the housing 120 and can receive the power generated by the magnetic induction or magnetic resonance from the transmitting coil 113, and the battery is connected to the receiving module 122 and is used to store the power received by the receiving coil 121.

Generally, the body 110 of the prior art wireless charging device 11 is designed to be a platform shape, and the volume of the body 110 of the prior art wireless charging device 11 is larger than the volume of the housing 120 of the prior art electronic device 12, so that the user can place the prior art electronic device 12 thereon. In the process of the prior art wireless charging device 11 transmitting power to the prior art electronic device 12, the user must specially approach the receiving coil 121 inside the prior art electronic device 12 to the transmitting coil 113 of the prior art wireless charging device 11, so that the transmitting coil 113 is aligned with the receiving coil 121 as much as possible, and the receiving coil 121 receives the power.

However, many users still have a need to operate the electronic device during the charging process, and when the electronic device is placed on the platform-shaped wireless charging device for wireless charging, the line of sight of the user cannot be parallel to the display screen of the electronic device, which causes a trouble in the operation of the user. In view of the above problem, chinese patent No. CN108668522 proposes a wireless charging device, in which a platform for placing an electronic device is lifted, so that the user's sight line can be parallel to the display screen of the electronic device, thereby facilitating the operation of the electronic device during the wireless charging process. However, the wireless charging device cannot be applied to electronic devices of various sizes. Take a larger electronic device, such as a tablet computer as an example: generally, the receiving coil in the electronic device is also disposed at the center of the interior of the electronic device, and the receiving coil in the electronic device is higher due to the larger size of the electronic device such as a tablet computer. When a larger-sized electronic device is placed on the wireless charging device, the distance between the receiving coil and the transmitting coil inside the wireless charging device is too large, thereby making wireless charging difficult.

Therefore, there is a need for a wireless charging device that is adaptable to electronic devices of various sizes.

Referring to fig. 2, fig. 3 and fig. 4, fig. 2 is a schematic structural diagram of a wireless charging device and an electronic device according to the present invention in a first preferred embodiment, fig. 3 is a schematic structural diagram of another perspective of the wireless charging device in the first preferred embodiment, and fig. 4 is an exploded schematic partial structure diagram of an adjustment module of the wireless charging device in the first preferred embodiment. The wireless charging device 2 of the present invention is used for carrying the electronic device 20 and transmitting power to the electronic device 20 in a wireless manner, and includes a base 21, a charging plate 22 and an adjusting module 23. The charging plate 22 is movable relative to the base 21 and has two functions: firstly, the electronic device 20 is carried together with the base 21, and secondly, the power is wirelessly transmitted to the electronic device 20 for wireless charging. The adjusting module 23 is connected to the base 21 and the charging plate 22, and functions to move the charging plate 22 relative to the base 21 and adjust the position of the charging plate 22. The adjusting module 23 includes a deforming mechanism 231 and a sliding component 232, wherein the deforming mechanism 231 is disposed on the base 21 and connected to the charging plate 22, and can swing relative to the base 21 to change the disposition status of the charging plate 22. The sliding assembly 232 is disposed on the deforming mechanism 231, and can slide the charging plate 22 relative to the base 21 along the first direction D1 to adjust the position of the charging plate 22.

Referring to fig. 3, fig. 4 and fig. 5, fig. 5 is a schematic partial structure diagram of a wireless charging module and an adjusting module of a wireless charging device according to a first preferred embodiment of the present invention. The charging plate 22 includes a case 221, a wireless charging module 222, and a fixing plate 223. The housing 221 can carry the electronic device 20, and the housing 221 has a connection slot 2211 disposed on the rear surface of the housing 221, such that the deformation mechanism 231 can extend into the connection slot 2211 to be connected to the housing 221. The wireless charging module 222 is disposed in the housing 221, and functions to transmit power to the electronic device 222 in a wireless manner, in the preferred embodiment, the wireless charging module 222 includes a transmitting coil and related electronic components, and the internal structure and operation of the wireless charging module 222 are well known to those skilled in the art and therefore will not be described again. The fixing plate 223 is disposed in the housing 221 and connected to the sliding element 232 and the wireless charging module 222, wherein the sliding element 232 operates to enable the charging plate 22 to slide along the first direction D1 relative to the base 21.

The sliding assembly 232 is disposed on the deforming mechanism 231, and is operable to slide the charging plate 22 relative to the base 21 along the first direction D1, so as to adjust the position of the charging plate 22. The sliding assembly 232 includes a guide rail 2321 and a sliding plate 2322, and the guide rail 2321 is fixed to the deformation mechanism 231. The sliding plate 2322 is coupled with the guide rail 2321 and is slidable with respect to the guide rail 2321, wherein the guide rail 2321 is disposed in the first direction D1 such that the sliding plate 2322 is slidable with respect to the guide rail 2321 in the first direction D1.

In fig. 3, the base 21 is shown to have a receiving cavity 211, and the receiving cavity 211 can receive the deforming means 231 therein for a small part or receive the deforming means 231 therein for a large part. When the deforming mechanism 231 swings to be mostly accommodated in the accommodating groove 211, the charging plate 22 can swing with respect to the base 21 to be in a covering state, as shown in fig. 6. When the deforming mechanism 231 swings and is accommodated in the accommodating groove 221 at least partially, the charging plate 22 can swing relative to the base 21 to be in a loaded state, as shown in fig. 2.

In the preferred embodiment, the deforming mechanism 231 is a swingable Hinge (Hinge) structure, and the internal structure and operation of the Hinge structure are well known to those skilled in the art and therefore will not be described in detail. Here, the guide rail 2321 is fixed to any one of the deformation mechanisms 231 such that the setting angle of the guide rail 2321 is parallel to the housing 221 of the charging plate 22, so that the sliding plate 2322 is slidable in the first direction D1 with respect to the guide rail 2321. In other words, the charging plate 22 is slidable in the first direction D1 with respect to the base 21.

Referring to fig. 2, fig. 6 and fig. 7, fig. 7 is a schematic structural diagram illustrating a charging plate of a wireless charging device according to a first preferred embodiment of the present invention being moved. In response to the operation of the adjusting module 23, the wireless charging device 2 can be in three states. Firstly, the method comprises the following steps: the coverage state of the wireless charging device 2 is shown in fig. 6. The coverage status is applicable to the situation that the electronic device 20 is not needed to be used in the wireless charging process, and only the electronic device 20 is placed on the platform-shaped wireless charging device 2. Secondly, the method comprises the following steps: the carrying state of the wireless charging device 2 is shown in fig. 2. The carrying state is applied to the situation that the user needs to use the electronic device 20 in the wireless charging process, and the carrying state can make the electronic device 20 placed on the wireless charging device 2 parallel to the line of sight of the user, so as to facilitate the use. Third, another carrying state of the wireless charging device 2, i.e. the configuration of the charging board 22 moving when the wireless charging device 2 is in the carrying state. The user can simply pull the charging pad 22 in the first direction D1 to slide the charging pad 22 relative to the base 21 in the first direction D1 away from the base 21 to form the loaded state, as shown in fig. 7. Another carrying status of the wireless charging device 2 is applied to a larger-sized electronic device, such as a tablet computer. So that the wireless charging module 222 in the wireless charging device 2 can be close to the receiving coil (not shown) inside the larger-sized electronic device.

In addition, the invention also provides a second preferred embodiment. Referring to fig. 8 and 9, fig. 8 is a schematic structural diagram of another perspective of the wireless charging device in the second preferred embodiment of the present invention, and fig. 9 is an exploded schematic partial structural diagram of another perspective of the wireless charging device in the second preferred embodiment of the present invention. The wireless charging device 3 of the present invention is used for carrying an electronic device (not shown) and transmitting power to the electronic device in a wireless manner, and includes a base 31, a charging plate 32 and an adjusting module 33. The base 31 has a receiving slot 311, and the charging plate 32 includes a housing 321, a wireless charging module (not shown in the figures) and a fixing plate 323, and the housing 321 has a connecting slot 3211. The structure of the preferred embodiment is substantially the same as that of the preferred embodiment, and the description thereof is omitted. The difference between the two is that the structure and operation of the adjusting module 33 of the preferred embodiment are slightly different.

The adjusting module 33 includes a deforming mechanism 331, a sliding component 332 and a rotating mechanism 333, wherein the deforming mechanism 331 is disposed on the base 31 and connected to the charging plate 32, and can swing relative to the base 31 to change the disposition status of the charging plate 32. The sliding member 332 is disposed on the deforming mechanism 331, and can slide the charging plate 32 relative to the base 31 along the first direction D1. The sliding assembly 332 includes a guide rail 3321 and a sliding plate 3322, and the structure of the sliding assembly 332 is the same as that of the above preferred embodiment, so the description thereof is omitted. The rotating mechanism 333 is provided on the sliding plate 3322 of the sliding member 332 and connected to the fixing plate 323 of the charging plate 32, and functions to adjust the installation angle of the charging plate 32 by allowing the charging plate 32 to rotate with respect to the sliding member 332.

As can be seen from fig. 9, the fixed plate 323 is connected to the rotating mechanism 333, and the rotating mechanism 333 is disposed on the sliding plate 3322 such that the charging plate 32 can rotate with respect to the sliding assembly 332. On the other hand, in response to the operation of the sliding assembly 332, the charging board 32 slides along the first direction D1 with respect to the base 31. In summary, the charging plate 32 can slide and rotate relative to the base 31 in response to the operation of the adjusting module 33. It should be noted that, in fig. 8, the shape of the connection slot 3211 on the housing 321 is different from the connection slot 2211 of the previous preferred embodiment, because the connection slot 3211 of the present preferred embodiment must accommodate a part of the deformation mechanism 231 therein, and the connection slot 3211 must have a larger space to accommodate the deformation mechanism 231 in response to the rotation of the charging plate 32, otherwise the charging plate 32 is blocked and cannot rotate smoothly. Therefore, the connection groove 3211 of the preferred embodiment is designed to have an L-shape. It is used for illustration only and not for limitation. In another preferred embodiment, a rectangular connecting slot can be used, but the size of the connecting slot must be larger than that of the connecting slot 2211 of the above preferred embodiment, so as to facilitate the rotation of the charging plate.

In the present preferred embodiment, the wireless charging device 3 can form three states shown in fig. 2, fig. 6 and fig. 7 in the foregoing preferred embodiment, and can also rotate the charging board 32 in another carrying state shown in fig. 7 relative to the base 31 to form an upright carrying state, as shown in fig. 10. The upright carrying state enables the electronic device to be carried on the wireless charging device 3 in an upright manner, so that a user can use the electronic device in the wireless charging process.

According to the above description, the wireless charging device of the invention utilizes the adjustment module to control the charging plate to move relative to the base, even rotate relative to the base, so as to adjust the position of the charging plate, so that the wireless charging module in the charging plate is as close as possible to the receiving coil in the electronic device, thereby improving the wireless charging efficiency. The adjusting module has a simple structure and can be easily fixed in the charging plate and the base. Therefore, the wireless charging device can wirelessly charge electronic devices with common sizes and electronic devices with larger sizes.

The above description is only a preferred embodiment of the present invention and should not be taken as limiting the claims, so that other equivalent changes and modifications without departing from the spirit of the present invention are intended to be included in the claims.
