Description

Technical Field

[0001] The invention relates to the field of foldable chargers, in particular to a foldable portable charger. Background Art

[0002] Mobile phones have become a must-have communication device for everyone. When users go out, they usually carry chargers to avoid insufficient power in their mobile phones. The most common chargers are wired, which is very inconvenient to charge, so more and more wireless chargers have appeared. Wireless chargers are devices that use the principle of electromagnetic induction to charge. Since the charger and the power-consuming device transmit energy through a magnetic field, there is no need to connect the two with wires. Therefore, the charger and the power-consuming device can have no exposed conductive contacts, which has many incomparable advantages over traditional chargers. With the emergence of smart phones and tablets, people use smart electronic products more and more frequently, and charging smart electronic products has become an indispensable thing in daily life. Traditional chargers need to carry multiple charging cables, which are inconvenient to store and use. There are no such troubles when using wireless chargers. One wireless charger can charge different models of smart electronic products. However, most of the existing wireless chargers are placed horizontally, and there are many inconveniences for users to use smart electronic products while charging, such as poor viewing angle or unstable position of electronic products.

[0003] There are some foldable mobile phone holders with adjustable angles in the prior art for observing electronic products at the best viewing angle. Such foldable mobile phone holders also have the function of wireless charging, but such products can only be regarded as a mobile phone holder rather than a charger. Users still need to sit upright to observe and cannot use them in a real handheld manner. In addition, high-power wireless fast charging generates a lot of heat, which will be concentrated on the back of the phone and shorten the battery life.

[0004] Chinese patent publication number: CN215120289U discloses a steplessly adjustable foldable wireless charger, which includes a charging unit and a supporting unit, one end of the charging unit is connected to one end of the supporting unit through a hinge structure. The charging unit includes a housing, a coil assembly and a circuit board, the coil assembly is electrically connected to the circuit board, and the coil assembly and the circuit board are both arranged inside the housing.

[0005] When using the above-mentioned stepless adjustable foldable wireless charger to charge a mobile phone, you can first swing the charging unit back and forth to adjust the appropriate angle, and then place the mobile phone on the charging unit. The charging unit can be used to wirelessly charge the mobile phone, and the adjusted angle of the charging unit can just support the mobile phone conveniently, so that the user can play with the mobile phone while charging. However, the user cannot take the mobile phone off while charging, and needs to touch the mobile phone carefully to avoid displacement. When playing with the mobile phone, it is very likely to cause the mobile phone to shift on the charging unit, which can easily cause the mobile phone charging to be intermittent, causing great damage to the mobile phone.

[0006] Chinese Patent Publication No.: CN116566025A discloses a foldable wireless charger, including a base, a rotating plate, a charging module, a movable plate, a limiting mechanism, etc. The upper right part of the base is rotatably connected to the rotating plate, the upper left part of the rotating plate is connected to the charging module, the upper right part of the rotating plate is slidably connected to the movable plate, and the rotating plate is provided with a limiting mechanism. The present invention controls the rotation of the screw by a dual-axis motor, so that the first sliding plate moves inward to automatically limit the front and rear sides of the mobile phone. At the same time, the first sliding plate will cause the second sliding plate to move inward and contact the mobile phone, thereby driving the first pressing plate to move downward to press and limit the top of the mobile phone, so as to facilitate users to use the mobile phone while charging.

[0007] In this solution, the mobile phone is firmly connected to the wireless charging module, but heat accumulation is further increased. The heat between the charger and the mobile phone is difficult to discharge due to being blocked by multiple structures. Summary of the invention

[0043] How it works In the folded state: the cooling base assembly 1 and the mobile phone limiting assembly 3 are closed, at this time, the separation support assembly 2 is hidden in the placement groove 5, and the structure on the mobile phone limiting assembly 3 is also hidden. At this time, the entire device has no protrusions on the outside, and the volume is small and easy to carry. When using, the mobile phone only needs to be placed on the device to realize wireless charging; In the unfolded state: the mobile phone limiting assembly 3 and the cooling base assembly 1 are pulled apart, and the separated support assembly 2 plays the role of supporting the two. The angle or distance between the two can be adjusted, so that the user can watch the mobile phone at a suitable angle. The bottom support 302 and the top support 303 of the mobile phone limiting assembly 3 can fix the mobile phone at this time; In the separated state: when the user wants to answer a call or play with the mobile phone at a close distance, he only needs to pull the short rod 202 off the long rod 201. At this time, the two are separated, and the mobile phone limit assembly 3 and the short rod 202 will be attached to the mobile phone, which will not affect the user's operation, and the shorter short rod 202 can also play a simple support effect; Active heat dissipation: When the user holds the mobile phone, the active fan 409 is turned on according to the heat generated by the mobile phone or the heat near the wireless charging module 402. When turned on, the outside air enters from the air inlet 407 of the conical base 406, and then passes through the wireless charging module 402 and the isolation plate 403 and is transferred to the air jet hole 411. At this time, the air jet hole 411 fits the mobile phone, and the airflow can take away the heat of the mobile phone from the curved groove 412; High-power fast charging cooling: When the short rod 202 is combined with the long rod 201, the mobile phone is supported for charging. At this time, high-power charging will generate high temperature, the active fan 409 stops working, and the upper surface temperature of the cooling silicon chip 102 decreases. After the turbofan 103 passes the outside air through the cooling silicon chip 102, the incoming air can be cooled down, and then the cold air can enter the closed box 401 along the long rod 201 and the short rod 202. At this time, the sealing gasket 408 can close the conical base 406, and then the cold air will surround the wireless charging module 402, enter the jet hole 411, and then take away the heat generated on the back of the mobile phone along the curved groove 412.
