Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging, and in particular to a wireless charging device. Background Art

[0002] Wireless charging technology originates from wireless power transmission technology and can be divided into two types: low-power wireless charging and high-power wireless charging. Low-power wireless charging usually adopts electromagnetic induction. High-power wireless charging usually adopts resonance (most electric vehicles use this method to charge). The power supply device (charger) transmits energy to the device using electricity. The device uses the received energy to charge the battery and also for its own operation. Since the charger and the device use energy to transmit energy through the magnetic field, there is no need for wires to connect the two, so the charger and the device using electricity can be made without exposed conductive contacts.

[0003] Wireless chargers are devices that use the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. A coil is placed at the sending and receiving ends. The sending coil sends an electromagnetic signal to the outside world under the action of electricity. The receiving coil receives the electromagnetic signal and converts it into current, thereby achieving the purpose of wireless charging. Wireless charging technology is a special power supply method that does not require a power cord, relies on electromagnetic wave propagation, and then converts electromagnetic wave energy into electrical energy, ultimately achieving wireless charging.

[0032] In this embodiment, a first accommodating cavity is provided inside the base 100, and the first wireless charging coil 120 and the control module 400 are both arranged in the first accommodating cavity; a second accommodating cavity is provided inside the rotating base 200, and the second wireless charging coil 210 is arranged in the second accommodating cavity.

[0033] Specifically, the first wireless charging coil 120 is used to wirelessly charge the electronic device placed on the base 100 .

[0034] The base 100 of this embodiment can be formed of plastic, glass, ceramic, aluminum alloy, zinc alloy, stainless steel, fiber composite material, other suitable materials or any combination of two or more of these materials. The base 100 can be formed in one piece (for example, the base 100 can be processed or molded into a single structure), or the base 100 can be formed by combining multiple structures (for example, the base 100 can be a structure with a cavity formed by splicing the front shell 130 and the rear shell 140).

[0035] The base 100 of this embodiment may be a regular shape, for example, the base 100 may be a rectangular structure, a cylindrical structure or a truncated cone structure. Of course, the base 100 may also be an irregular shape. The embodiment of the present application does not limit the specific shape of the base 100. A first accommodating cavity is provided inside the base 100, and the first wireless charging coil 120 is accommodated in the first accommodating cavity. When an electronic device with a wireless charging function is placed on the base 100, the wireless charging device can wirelessly charge the electronic device through the first wireless charging coil 120 in the base 100.

[0036] In this embodiment, when the rotating base 200 is in an open state, the second wireless charging coil 210 is used to wirelessly charge the electronic device placed on the rotating base 200 .

[0037] The rotating base 200 can be formed of plastic, glass, ceramic, aluminum alloy, zinc alloy, stainless steel, fiber composite material, other suitable materials or any combination of two or more of these materials. The rotating base 200 can be formed in one piece (for example, the rotating base 200 can be processed or molded into a single structure), and the rotating base 200 can also be formed by combining multiple structures (for example, the rotating base 200 can be a structure with a cavity formed by splicing a front shell and a rear shell, etc.).

[0038] The rotating base 200 of this embodiment may be of a regular shape, for example, the rotating base 200 may be of a rectangular structure, a cylindrical structure or a truncated cone structure, etc. Of course, the rotating base 200 may also be of an irregular shape. The embodiment of the present application does not limit the specific shape of the rotating base 200. The rotating base 200 is provided with a second accommodating cavity, and the second wireless charging coil 210 is accommodated in the second accommodating cavity. When the rotating base 200 is rotated out of the storage slot 110 and an electronic device with a wireless charging function is placed on the rotating base 200, the wireless charging device can wirelessly charge the electronic device through the second wireless charging coil 210 in the rotating base 200.

[0039] In this embodiment, the rotating base 200 is smaller than the base 100 .

[0040] It should be noted that, in the description of this application, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0041] In the embodiment of the present application, the wireless charging device includes a base 100, a first wireless charging coil 120, a rotating base 200, a second wireless charging coil 210 and a bracket 300. The bracket 300 is rotated to change the angle between the base 100 and the desktop, thereby adjusting the angle of the device to be charged magnetically attracted to the wireless charging device, so that consumers can see the device to be charged at a better angle, especially when the screen of the device to be charged is turned on, which is more convenient to use, and the rotating base 200 can be rotated into the storage slot 110; when the rotating base 200 is opened at a certain angle relative to the base 100, the first wireless charging coil 120 and the second wireless charging coil 210 can both be used to wirelessly charge the electronic device. The wireless charging device is both portable and can meet the needs of charging multiple charging devices at the same time.

[0042] In this embodiment, the ratio of the diameter of the first wireless charging coil 120 to the diameter of the second wireless charging coil 210 is greater than or equal to 1.3.

[0043] In this embodiment, the charging power of the first wireless charging coil 120 is greater than the charging power of the second wireless charging coil 210 .

[0044] In a specific embodiment, the first wireless charging coil 120 is mainly used to wirelessly charge higher power devices (such as mobile phones, tablets, etc.), while the second wireless charging coil 210 is used to wirelessly charge lower power devices (such as watches, headphones, etc.).

[0045] In this embodiment, the thickness of the rotating base 200 is not greater than the depth of the receiving groove 110 .

[0046] The thickness of the rotating base 200 of this embodiment is not greater than the depth of the receiving groove 110, so that after the rotating base 200 is rotated into the receiving groove 110, the rotating base 200 will not protrude from the outer surface of the base 100, effectively reducing the volume of the wireless charging device after the rotating base 200 is received.

[0047] In another embodiment, the front shell 130 of the base 100 is also partially raised in the area corresponding to the first wireless charging coil 120. After the rotating seat 200 is received in the receiving groove 110, the rotating seat 200 protrudes out of the receiving groove, and the protruding surface of the rotating seat 200 is not higher than the protruding surface of the front shell 130 (for example, the protruding surface of the rotating seat is flush with the protruding surface of the front shell 130 corresponding to the first wireless charging coil 120).

[0048] In this embodiment, the wireless charging device also includes a connecting component, which is used to rotatably connect the rotating seat to the base, and the connecting component includes one or more combinations of a rotating shaft 600, a damping member, a self-locking member, a self-closing member, a magnetic attraction component, a resettable elastic structure or a support member.

[0049] In one embodiment, a rotation hole is provided on the side wall of the receiving groove 110 , one end of the rotation shaft 600 is rotatably disposed in the rotation hole, and the other end of the rotation shaft 600 is fixedly connected to the rotation seat 200 .

[0050] In another embodiment, the connecting member includes a rotating shaft 600 , a rotating hole is provided on the side wall of the rotating seat 200 , one end of the rotating shaft 600 can be rotatably disposed in the rotating hole, and the other end of the rotating shaft 600 is fixedly connected to the side wall of the storage groove 110 .

[0051] In this embodiment, the base 100 is provided with an escape opening 132 communicating with the receiving groove 110 , and the escape opening 132 is used for allowing a finger to be inserted into the receiving groove 110 to rotate out of the rotating base 200 .

[0052] In this embodiment, when the data cable accommodating groove 131 and the receiving groove 110 are arranged side by side, the avoidance opening 132 is located between the data cable accommodating groove 131 and the receiving groove 110, and is connected to both the data cable accommodating groove 131 and the receiving groove 110, so that the finger can be inserted into the data cable accommodating groove 131 through the avoidance opening 132 to take out the data cable 700.

[0053] In this embodiment, a non-slip groove is provided on one side of the rotating seat 200 close to the escape opening. When the rotating seat 200 is received in the receiving groove 110, the non-slip groove corresponds to the escape opening 132, making it easy to pull out the rotating seat 200 with fingers.

[0054] In another embodiment, a non-slip protrusion is provided on one side of the rotating seat 200 close to the escape opening 132. When the rotating seat 200 is received in the receiving groove 110, the non-slip protrusion corresponds to the escape opening 132, making it easy to pick out the rotating seat 200 with fingers.

[0055] The bracket 300 is rotatably connected to the base 100 , and the bracket 300 can rotate relative to the base 100 within a preset angle range.

[0056] The preset angle range may be 0 to 90 degrees. When the base 100 does not need support, there is no angle between the bracket 300 and the base 100. When the angle of the base 100 relative to the desktop needs to be adjusted, the bracket 300 is rotated so that the bracket 300 is rotated relative to the base 100 until the angle between the bracket 300 and the base 100 is greater than 0 degrees and less than or equal to 90 degrees.

[0057] Among them, the base 100 includes a front side provided with the storage groove, a back side arranged opposite to the front side, a top side close to the first wireless charging coil, a bottom side of the storage groove and two side sides located between the top side and the bottom side, the side side is provided with a side groove at one end close to the bottom side, the bottom side is provided with a bottom groove, the bottom groove and the two side grooves are connected to form a U-shaped limiting groove 141 with an opening toward the top side, and the U-shaped limiting groove 141 is recessed from the back side of the base 100 toward the front side of the base 100; the bracket 300 is U-shaped, and the two ends of the bracket 300 are rotatably connected to the two side sides of the base 100 respectively, and the bracket 300 can be rotated into the U-shaped limiting groove 141.

[0058] Specifically, the U-shaped limiting groove 141 forms a step with the side surface of the base 100. When the bracket 300 is arranged in the U-shaped limiting groove 141, the step limits the bracket 300 toward the front direction of the base 100, so that the bracket 300 can only rotate toward the back direction of the base 100. When the bracket 300 is rotated to a certain angle (for example, 90 degrees), one side wall of the bracket 300 abuts against the end surface of the side groove, so that the bracket 300 cannot continue to rotate toward the back direction of the base 100, thereby limiting the bracket 300 and limiting the rotation angle of the bracket 300 within a predetermined range.

[0059] See also Figure 4 The end surface of the base 100 close to the receiving groove 110 is the bottom surface, and the receiving groove 110 is provided with a notch in the direction close to the bottom surface of the base 100, and the width of the notch is not less than the width of the rotating seat 200, and the rotating seat 200 can be rotatably connected to the end of the receiving groove 110 close to the notch.

[0060] Since the receiving groove 110 is provided with the notch, the rotating seat 200 can rotate relative to the base 100 at an angle greater than 90 degrees (for example, 180 degrees).

[0061] Specifically, when the bracket 300 on the base 100 is opened, the base 100 stands on the desktop at a certain angle (for example, the angle between the front of the base 100 and the desktop is 120°). When a low-power device needs to be wirelessly charged, the rotating base 200 is rotated out of the storage slot 110 so that the rotating base 200 is parallel to the desktop. The low-power device is placed on the rotating base 200 for wireless charging. At this time, the angle formed between the rotating base 200 and the base 100 is 120°.

[0062] When there is no need to charge the low-power electronic device, the rotating base 200 is stored in the storage slot 110. At this time, the working direction of the second wireless charging coil 210 is toward the rear shell 140 of the base 100, which is opposite to the working direction of the first wireless charging coil 120. In another specific implementation, the working direction of the second wireless charging coil 210 is toward the front shell 130 of the base 100, that is, the working direction of the second wireless charging coil 210 is set in the same direction as the first wireless charging coil 120.

[0063] See also Figure 3 The control module also includes an electronic control unit and a charging interface 420, both of which are arranged on the base 100, and the electronic control unit is electrically connected to the first wireless charging coil 120, the second wireless charging coil 210, the rechargeable battery 500 and the charging interface 420 respectively; one end of the charging interface 420 is electrically connected to the electronic control unit, and the other end is arranged on the outer surface of the base 100.

[0064] The end of the charging interface 420 away from the electronic control unit can be arranged on the side of the base 100 and located between the U-shaped limiting groove 141 and the front shell 130 to avoid interference with the data cable 700 during charging.

[0065] In this embodiment, the electronic control unit includes a PCB board 410 , and the wireless charging device further includes an indicator light and a power switch 430 . The indicator light and the power switch 430 are both disposed on the side wall of the base 100 .

[0066] In one embodiment, the indicator light and the power switch 430 are arranged side by side at the lower end of the left side wall of the base 100 and are located between the U-shaped limiting groove 141 and the front shell 130 to avoid interference with the bracket 300.

[0067] The indicator light, the power switch 430 and the charging interface 420 are all arranged between the U-shaped limiting groove 141 and the front shell 130, so that the opening and closing of the bracket 300 does not affect the use of the charging interface 420 and the power switch 430.

[0068] In this embodiment, the charging interface 420 can be a Micro USB interface, a USB Type-C interface, or a miniUSB interface, etc., which is not limited here.

[0069] In this embodiment, the base 100 further includes a support frame 150, which is disposed in the first accommodating cavity. The support frame 150 is fixedly connected to the rear shell 140 through a support column. A placement space is formed between the back of the support frame 150 and the rear shell 140. The rechargeable battery 500 and the PCB board 410 are both disposed in the placement space, and the PCB board 410 is located above the rechargeable battery 500. A circular mounting groove 151 is provided on the front side of the support frame 150 at one end close to the top surface of the base 100, and an annular mounting groove is provided on the outer periphery of the circular mounting groove 151. The first wireless charging coil 120 is disposed in the circular mounting groove 151, and the annular magnet assembly is disposed in the annular mounting groove.

The support frame 150 is provided with a flange 152 at one end away from the circular mounting groove 151, and the flange 152 is arranged to form the storage groove 110. A notch is provided at a position corresponding to the storage groove 110 on the front shell 130, so that the front shell 130, the rear shell 140 and the flange 152 are arranged to form the first accommodating cavity.

[0071] The wireless charging device of this embodiment has a compact structure, a small size and is easy to carry due to the spatial arrangement between various components.

[0072] In this embodiment, a data cable receiving groove 131 is provided on the base 100 , and the wireless charging device further includes a data cable 700 , one end of the data cable 700 is electrically connected to the electronic control unit, and the other end is provided in the data cable receiving groove 131 .

[0073] In this embodiment, the data cable receiving groove 131 is adapted to the connector of the data cable 700, the connector of the data cable 700 is arranged in the data cable receiving groove 131, the data cable 700 can also have a hanging rope function, the data cable receiving groove 131 is arranged on the front of the base 100, located at a corner position close to one end of the storage groove 110, and will not affect the use of the data cable 700 when the bracket 300 is used. And the data cable receiving groove 131 is connected with the avoidance port, so that the finger can be inserted into the data cable receiving groove 131 through the avoidance port to pull out the data cable 700.

[0074] In another embodiment, the data cable accommodating groove 131 is adapted to the connector of the data cable 700, and the connector of the data cable 700 is disposed in the data cable accommodating groove 131. A portion of the data cable 700 is received in the data cable accommodating groove while a portion is exposed outside the device. The data cable 700 can also function as a lanyard. The data cable accommodating groove 131 is disposed on the front side of the base 100, at a corner position close to one end of the first wireless charging coil 120, and will not affect the use of the data cable 700 when the bracket 300 is used.

[0075] Of course, the data cable accommodating groove 131 avoids the side area of ​​the first wireless charging coil 120 and the storage groove 110 on the front of the base 100; or, the data cable accommodating groove 131 is on the side of the base 100, so that the operation of the first wireless charging coil or the second wireless charging coil will not affect the use of the data cable 700.
