Description

TECHNICAL FIELD

[0001] The present application relates to the field of foldable chargers, in particular to a foldable portable charger. BACKGROUND

[0002] Mobile phones have become a necessary communication device for people. When users go out, they usually carry a charger to avoid insufficient battery. The most common charger is wired, and it is very inconvenient to charge with a wired charger. Therefore, 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 device transfer energy through a magnetic field, they do not need to be connected by a wire. Therefore, the charger and the power device can be made without exposed conductive contacts, which has many advantages compared to traditional chargers. With the advent of smartphones and tablets, people use smart electronic products more and more frequently, and charging smart electronic products has become an essential part of daily life. Traditional chargers require the carrying of multiple charging cords, which is inconvenient for storage and use. Using a wireless charger eliminates these worries, and one wireless charger can charge different models of smart electronic products. However, existing wireless chargers are mostly placed horizontally, and users have many inconveniences when using smart electronic products while charging, such as poor viewing angle or unstable electronic product position.

[0003] Some adjustable angle folding phone holders exist in the prior art for optimal viewing angle observation of electronic products. This type of folding phone holder also has the function of wireless charging, but this type of product can only be considered as a phone holder rather than a charger. Users still need to sit straight to observe, and cannot be truly handheld. In addition, the heat generated during high-power wireless fast charging is large, and the heat will concentrate on the back of the phone, shortening the service life of the battery.

[0004] Chinese Patent Publication No. CN215120289U discloses a stepless adjustment foldable wireless charger, which includes a charging unit and a support unit. One end of the charging unit is connected to one end of the support unit through a hinge structure. The charging unit includes a housing, a coil assembly, and a circuit board. The coil assembly and the circuit board are electrically connected, and both are arranged inside the housing.

[0005] When the above-mentioned stepless adjustment foldable wireless charger is used to charge a mobile phone, the charging unit can be first adjusted to a suitable angle by swinging it forward and backward, and then the mobile phone can be placed on the charging unit, so that the mobile phone can be wirelessly charged by the charging unit, and the angle of the charging unit after adjustment can conveniently support the mobile phone, so that the user can play the mobile phone while charging. However, the user cannot take the mobile phone out during charging, and also needs to carefully touch the mobile phone to avoid displacement. When playing the mobile phone, it is very likely that the mobile phone will be displaced on the charging unit, which can easily cause the mobile phone to charge intermittently and cause great damage to the mobile phone.

[0006] Chinese Patent Publication No. CN116566025A discloses a foldable wireless charger, which comprises a base, a rotating plate, a charging module, a moving plate, a limiting mechanism and the like. The base is rotatably connected with the rotating plate at the right upper part, the rotating plate is connected with the charging module at the left upper part, the rotating plate is slidably connected with the moving plate at the right upper part, and the rotating plate is provided with the limiting mechanism. The double-shaft motor controls the rotation of the screw rod, so that the first sliding plate moves inward to automatically limit the front and rear sides of the mobile phone, and the first sliding plate moves the second sliding plate inward and contacts 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 the user to use the mobile phone while charging.
