Technical Field

[0001] The present invention relates to the technical field of wireless charging devices, and particularly to a foldable wireless charger. Background Art

[0002] A wireless charger is a device that uses the principle of electromagnetic induction for charging. Since energy is transmitted between the charger and the electrical device by a magnetic field and there is no wire connection between the two, both the charger and the electrical device can be made without exposed conductive contacts, having many incomparable advantages compared with traditional chargers.

[0003] With the emergence of smartphones and tablets, people use smart electronic products more and more frequently, and charging smart electronic products has become an essential thing in daily life. Traditional chargers require multiple charging cables to be carried, which is inconvenient for both storage and use. Using a wireless charger eliminates these troubles, and one wireless charger can charge different models of smart electronic products. However, most existing wireless chargers are horizontally placed, and there are many inconveniences for users to use smart electronic products while charging, such as poor viewing angles or unstable positions of the electronic products.

[0004] In view of this, there is an urgent need for a new technical solution to solve the above technical problems. Summary of the Invention

[0052] Embodiment 1

[0053] Please refer to Figures 1 to 5 , a preferred embodiment of the present invention provides a foldable wireless charger 100, which can wirelessly charge smart electronic products; at the same time, the foldable wireless charger 100 can be used as a stand to support the smart electronic products.

[0054] The smart electronic products may be portable mobile electronic products that support wireless charging, such as mobile phones, tablet computers, laptop computers, e-readers, etc.

[0055] The foldable wireless charger 100 includes a base 1, a wireless charging module 2, a flipping assembly, and a bracket 3.

[0056] Specifically, in this embodiment, the base 1 is in the shape of a disc. Correspondingly, the wireless charging module 2 as a whole is also in the shape of a disc. However, this does not mean that the present invention has special limitations on the outer contour. In some other embodiments, the base 1 and the wireless charging module 2 can also be square, oval or other geometric shapes.

[0057] The wireless charging module 2 is located above the base 1.

[0058] Please refer to Figure 5 , specifically, the wireless charging module 2 includes a charging coil 21, an upper charger cover 22 and a lower charger cover 23. Among them, the upper charger cover 22 and the lower charger cover 23 are buckled up and down to form a housing with an inner cavity, and the charging coil 21 is fixedly installed in the inner cavity.

[0059] The charging coil 21 is a component in the field of wireless charging technology and belongs to the prior art. For its structure and installation matters, they will not be elaborated here.

[0060] Please refer to Figure 2 and Figure 5 , specifically, in this embodiment, the base 1 includes a top shell 11 and a bottom shell 12, and the top shell 11 and the bottom shell 12 are detachably buckled together to form the base 1. A cavity is provided inside the base 1 for installing a circuit board 61 and other components.

[0061] It should be noted that there are various forms of the detachable connection method between the top shell 11 and the bottom shell 12. For example, on the opposite surfaces of the edges of the two, a buckle and a slot are respectively provided, and the buckle is snapped into the slot, so that the top shell 11 and the bottom shell 12 can be fixedly connected; another example is that the two are attached up and down, and then the two are fixed with screws; all technical solutions that achieve the detachable connection of the two should be included in the protection scope of the present invention.

[0062] More specifically, the top shell 11 is in the shape of a frustum of a cone, and its vertical section is an isosceles trapezoid. This shape setting can increase the side surface area of the base 1, which is convenient for setting functional components such as control keys on the side of the base 1, such as setting a bracket opening and closing key 62; at the same time, the side is inclined, which is more convenient to operate than a vertical side. For example, by pressing the bracket opening and closing key 62, the wireless charging module 2 can be unfolded and folded, and the charger will not move. It should be noted that the bracket opening and closing key 62 can be a conventional physical key or a touch key; in this embodiment, a physical key is adopted.

[0063] The upper surface of the top shell 11 is recessed downward to form a receiving groove 110 for receiving the wireless charging module 2, which is beneficial to improving the overall aesthetics.

[0064] The flipping component is connected between the base 1 and the wireless charging module 2, and is used to drive the wireless charging module 2 to flip between a flat state and an inclined state.

[0065] Specifically, in this embodiment, the flipping component includes a first bracket 41, a second bracket 42 and a driving device.

[0066] Please refer to Figure 3 、 6 Figures 6, 8, 10 and 12. The first bracket 41 and the second bracket 42 are pivotally connected to the base 1 so as to be able to flip in the same direction, and the second bracket 42 is located behind the first bracket 41; the other ends of the first bracket 41 and the second bracket 42 are correspondingly hinged to the back surface of the wireless charging module 2, and the length of the second bracket 42 is greater than that of the first bracket 41.

[0067] More specifically, both the first bracket 41 and the second bracket 42 are plate-shaped, and two opposite sides of the plate are respectively connected to the base 1 and the back surface of the wireless charging module 2.

[0068] Among them, the connection position of the first bracket 41 and the base 1 is at a position closer to the front of the base 1, and the connection position of the second bracket 42 and the base 1 is at the rear edge of the base 1; while the connection position of the first bracket 41 and the wireless charging module 2 is at the front edge of the wireless charging module 2, and the connection position of the second bracket 42 and the wireless charging module 2 is at a position closer to the front of the wireless charging module 2.

[0069] It should be noted that the connection between the two brackets and the base 1 and the wireless charging module 2 is realized through a plurality of rotating shafts. This kind of pivoting structure and method is relatively common in the prior art and will not be elaborated here.

[0070] Since the first bracket 41 and the second bracket 42 are plate-shaped structures, they have a certain volume. In order to make the structure of the entire charger more compact and miniaturized, the middle part of the top shell 11 further sinks downward to form a groove 111 for accommodating the two brackets. The shape of the groove 111 matches the shape of the two brackets to accommodate the two brackets to the maximum extent and reduce the folding height of the entire charger.

[0071] In this way, when the first bracket 41 flips upward, it can drive the second bracket 42 to flip in the same direction. At this time, the wireless charging module 2 slowly lifts and flips simultaneously; the flipping direction of the wireless charging module 2 is opposite to the flipping direction of the two brackets.

[0072] It can be understood that the structures and shapes of the first bracket 41 and the second bracket 42 should not be limited to the above-mentioned plate shape, and can also be frame type or other structures. As long as the technical solutions do not deviate from the purpose of the present invention, they should fall within the protection scope of the present invention.

[0073] The output shaft of the driving device is synchronously and transmission-connected to the pivot shaft of the first bracket 41 or the second bracket 42.

[0074] Please refer to Figure 3 and Figure 5 , specifically in this embodiment, the driving device is a driving motor 5, and the driving motor 5 is synchronously and transmission-connected to the rotating shaft 410 of the first bracket 41.

[0075] To save space, the output shaft of the driving motor 5 is perpendicular to the rotating shaft 410, and the synchronous transmission connection between the two is achieved through bevel gears 51.

[0076] It is worth mentioning that in some other embodiments, the output shaft of the driving motor 5 can also be linearly connected to the rotating shaft 410 through a coupling. Such a layout requires more lateral space inside the charger. Of course, in some other embodiments, the output shaft of the driving motor 5 can also be connected to the rotating shaft 410 through transmission gears. Any technical solution that does not deviate from the purpose of the present invention shall fall within the protection scope of the present invention.

[0077] It should be noted that in this embodiment, the rotating shaft 410 of the first bracket 41 connected to the base 1 is the driving shaft, which is fixed at the pivot of the first bracket 41. That is, when the rotating shaft 410 rotates, the first bracket 41 rotates accordingly; there is no such limitation for the rotating shafts at other connection points.

[0078] In addition, in some other embodiments, the driving motor 5 can also be synchronously and transmission-connected to the pivot shaft of the second bracket 42, and the purpose of driving the wireless charging module 2 to rotate can also be achieved.

[0079] Please refer to Figure 2 and Figure 3 , there are two brackets 3, which are respectively arranged at both ends of the first bracket 41. The two brackets 3 are rotatably mounted on the base 1 and are used to support the terminal to be charged.

[0080] In this embodiment, the bracket 3 is transmission-connected to the rotating shaft 410 of the first bracket 41 connected to the base 1.

[0081] Please refer to Figure 7 , 9 , 11 and 13. Specifically, the bracket 3 includes an integral main body part 31 and a supporting part 32, and a shaft hole 311 is provided on the main body part 31. The two brackets 3 are respectively sleeved on the outer ends of the corresponding rotating shafts 410 through the shaft holes 311.

[0082] Moreover, a structure for non-synchronous rotation is provided between the rotating shaft 410 and the shaft hole 311 of the bracket 3 in this embodiment. Specifically:

[0083] The outer peripheral wall of the rotating shaft 410 is convex in radial direction to form a toggle tooth 411, and the inner peripheral wall of the shaft hole 311 of the bracket 3 is convex in radial direction to form a stopper 312. The toggle tooth 411 and the stopper 312 can interfere with each other at a specific angle.

[0084] When the rotating shaft 410 rotates to a preset angle, the shifting teeth 411 interfere with the stopper 312 , thereby driving the bracket 3 to flip upward.

[0085] Exemplarily, in the initial state, the bracket 3 and the first support 41 are both in a horizontal state (eg Figure 7 shown);

[0086] The rotating shaft 410 rotates, driving the first bracket 41 to flip upward, and at this time, the shifting tooth 411 has not yet abutted against the stopper 312, so it will not drive the bracket 3 to flip together (such as Figure 9 shown);

[0087] When the rotating shaft 410 rotates by a preset angle (eg, 90°), the shifting tooth 411 and the stopper 312 interfere with each other (eg, Figure 11 As shown), the bracket 3 is then turned over, and finally the bracket 3 is in a position to support the terminal to be charged (as shown). Figure 13 shown).

[0088] When the rotating shaft 410 rotates in the reverse direction, the first bracket 41 is driven to flip downward, and the bracket 3 flips downward together with the rotating shaft 411 under the action of its own gravity;

[0089] When the bracket 3 returns to the initial position, ie, the horizontal position, the bracket 3 will no longer continue to flip, but the rotating shaft 410 will still drive the first bracket 41 to continue to flip downward until the first bracket 41 also returns to the initial position (ie, the horizontal position).

[0090] Preferably, an angle is set between the main body 31 and the supporting portion 32, that is, the bracket 3 is in a broken line shape. This setting is to ensure that when the bracket 3 is in the final position, the angle between the supporting portion 32 of the bracket 3 and the wireless charging module 2 is equal to or slightly less than 90°, which is used to provide a stable support for the terminal to be charged.

[0091] It is understandable that the main body 31 and the supporting portion 32 of the bracket 3 can also be directly set to a straight line shape, as long as the above-mentioned preset angle is set reasonably. It can also ensure that when the bracket 3 is in the final position, the angle between the supporting portion 32 of the bracket 3 and the wireless charging module 2 is equal to or slightly less than 90°.

[0092] The foldable wireless charger 100 of this embodiment drives the wireless charging module 2 to flip between a flat state and an inclined state through a flipping component; when the wireless charging module 2 is in the inclined state, the terminal to be charged can be placed obliquely, so as to provide a better viewing angle, that is, when charging, the user can still obtain a better use experience; at the same time, the bracket 3 flips upward and supports under the terminal to be charged, which can ensure that the position of the terminal to be charged is more stable and there will be no falling phenomenon.

[0093] During specific use, the wireless charging module 2 can flip between a flat state and an inclined state, so that the terminal to be charged can be in three positions: flat, vertically inclined, and horizontally inclined. Among them, the vertically inclined and horizontally inclined positions meet the user's habit of viewing intelligent electronic products, so as to obtain a better viewing experience.

[0094] Please refer to Figure 5 , as a further improvement, the foldable wireless charger 100 of this embodiment further includes an ambient light component for indicating different use states of the charger. The ambient light component includes an ambient light lamp board 81, a light guide plate 82, and a light homogenizing plate 83. The ambient light lamp board 81, the light guide plate 82, and the light homogenizing plate 83 are all circular, stacked on top of each other, and installed at the peripheral position of the base 1. Among them, the light homogenizing plate 83 is exposed on the outer surface of the base 1. A plurality of lamp beads are provided on the ambient light lamp board 81, and the light guide plate 82 is used to guide the light of the lamp beads onto the light homogenizing plate 83.

[0095] The charger can have multiple use states, such as slow charging, fast charging, the early stage of charging, the late stage of charging, etc. The current state of the charger can be correspondingly indicated by setting the lighting color, frequency, etc. of the ambient light component, which is convenient for users to use.

[0096] Preferably, an anti-slip silica gel sheet 91 is further provided on the bottom surface of the base 1 to prevent the foldable wireless charger 100 from moving randomly.

[0097] Embodiment Two

[0098] When the existing wireless charger is working, it cannot dissipate the heat of the charger body and the mobile phone well. Either no fan is set, or a fan is set but the mobile phone cannot be cooled together. Therefore, the existing wireless charger cannot charge at full speed in the highest speed state: after charging for a period of time, the frequency needs to be reduced for slow charging when the heat reaches, and the frequency is increased for fast charging after the heat dissipates, and so on, which prolongs the charging time.

[0099] To solve the above problems, a heat dissipation structure is further added in this embodiment on the basis of Embodiment One.

[0100] Please refer to Figure 2 and Figure 3, specifically in this embodiment, the heat dissipation structure includes a heat dissipation fan 71 and an air outlet 72. The heat dissipation fan 71 is installed inside the base 1, and the air outlet 72 is opened on the shell wall of the base 1.

[0101] More specifically, the air outlet 72 is opened on the top shell 11, and the air outlet 72 is located on the front half side of the top shell 11.

[0102] The working principle of the heat dissipation structure in this embodiment is as follows:

[0103] The heat dissipation fan 71 works, and cold air blows from inside the base 1 to the outside of the base 1.

[0104] When the charger is in a flat state, the cold air blows towards the wireless charging module 2 and dissipates heat from it.

[0105] When the charger is in an inclined state, both the wireless charging module 2 and the terminal to be charged are also in an inclined state, and the edges of the wireless charging module 2 and the terminal to be charged just face the air outlet 72. The cold air blows out from the air outlet 72 and acts on the wireless charging module 2 and the terminal to be charged, dissipating heat from both of them simultaneously, and the effect is excellent.

[0106] Please refer to Figure 2 , as one of the preferred solutions, the air outlet 72 is a plurality of strip-shaped grids arranged in parallel, and the extending direction of the strip-shaped grids is the same as the direction of the rotating shaft 410 of the first bracket 41. This setting can improve the heat dissipation effect.

[0107] Of course, in some other embodiments, the air outlet 72 can also be replaced with a plurality of round holes, a plurality of square holes, etc.

[0108] Please refer to Figure 3 , further, the heat dissipation fan 71 is an ultra-thin turbo fan. This ultra-thin turbo fan can not only provide a strong air-cooling effect, but also reduce the thickness of the entire charger, which is beneficial to reducing the volume of the charger.
