Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless charging technology, and in particular to a foldable wireless charger. Background Art
[0002] A wireless charger is a device that uses the principle of electromagnetic induction to charge devices. Its principle is similar to that of a transformer. By placing a coil at both the transmitting and receiving ends, the transmitting coil emits electromagnetic signals to the outside world under the action of electricity, and the receiving coil receives the electromagnetic signals and converts them into current, thereby achieving the purpose of wireless charging. Wireless charging technology is a special power supply method. It does not require power cords, but relies on electromagnetic waves to propagate and then converts the electromagnetic wave energy into electrical energy, ultimately realizing wireless charging.
[0003] A search revealed a foldable wireless charger disclosed in Chinese Patent Publication No. CN219554671U. The charger includes a charging base, a first charging head, and a connecting rod. The charging base comprises a housing and a power supply module. The housing has a mounting block, and the mounting block has a conductive block. The connecting rod has a cavity, with a first connector and a second connector mounted at each end. The first connector is hinged to the mounting block, and the second connector is hinged to the first charging head. A spring pin is located in the first connector. When the connecting rod rotates along the hinge to the working position, the spring pin contacts the conductive block to form a conductive connection. The advantages of this invention are: by setting a foldable connecting rod, with both ends hinged to the charging base and the charging head respectively, the connecting rod can be folded onto the charging base when not in use, effectively reducing the overall space occupied and facilitating use and portability. The spring pin inside the connecting rod contacts or separates from the conductive block on the charging base as the connecting rod rotates, realizing power on / off operation, making it highly practical.
[0004] While the above solution allows the wireless charger to be folded, it is difficult to adjust the height of the first charging head. Furthermore, after folding, the first charging head will extend to the front of the casing, which not only takes up a lot of space but also makes the first charging head susceptible to damage from impacts.
[0005] To address these issues, we propose a foldable wireless charger. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Please see Figure 1-5In this utility model, a foldable wireless charger includes a housing 1. The upper surface of the housing 1 has an opening 21. The inner wall of the opening 21 is rotatably connected to a perforated connecting seat 4 via a pin. A connecting ring 5 is fixedly connected to the back of the perforated connecting seat 4. A first charging head 7 is fixedly installed on the inner wall of the connecting ring 5. The upper surface of the housing 1 has a stepped groove 2 and a control groove 8. The inner bottom wall of the housing 1 is fixedly connected to two upright plates 17. The sides of the two upright plates 17 that are close to each other have sliding grooves 18. The inner wall of each sliding groove 18 is slidably connected to a slider 24. The sides of the two sliders 24 that are close to each other are fixedly connected to a control seat 22.
[0025] The bottom surface of the control base 22 is provided with a wire groove 23. The inner wall of the control base 22 is hinged with a square tube 9 by two pins. The outer surface of the square tube 9 is hinged with a through tube 10 by two pins. The top end of the through tube 10 is fixedly installed with a second charging head 11. The inner wall of the housing 1 is fixedly installed with a power supply module 14. The upper surface of the power supply module 14, the inner wall of the first charging head 7, and the inner wall of the second charging head 11 are all fixedly installed with coil modules 13. Each coil module 13 is electrically connected to the power supply module 14. The coil module 13 can work with the power supply module 14 to charge the electronic device. The control base 22 can slide back and forth through the slide groove 18 and the slider 24, thereby causing the control base 22 to push the square tube 9, which in turn pushes the through tube 10 to adjust the height of the second charging head 11.
[0026] In this embodiment, the input end of the power supply module 14 is fixedly connected to a charging plug 15. The rear end of the charging plug 15 passes through the housing 1 and extends to the rear of the housing 1. By providing the charging plug 15, the power supply module 14 can be connected to a power source to ensure power supply when charging electronic devices.
[0027] In this embodiment, a baffle 12 is fixedly connected to the back of the second charging head 11. The baffle 12 is adapted to the stepped groove 2. The baffle 12 can protect the second charging head 11 after it is folded, preventing the second charging head 11 from being squeezed and bumped when it is not in use.
[0028] In this embodiment, the inner wall of the opening 21 is provided with a groove 16, and the bottom surface of the housing 1 is fixedly connected with a rubber anti-slip pad 19. The groove 16 makes it easy to pull the connecting ring 5, thereby facilitating the rotation of the first charging head 7 to support and charge the electronic device. The rubber anti-slip pad 19 increases the friction of the bottom surface of the housing 1, preventing slippage during use.
[0029] In this embodiment, a baffle 3 is provided below the stepped groove 2. The upper surface of the baffle 3 is fixedly connected to the inner top wall of the housing 1. The baffle 3 can block the stepped groove 2 to prevent foreign objects from entering the interior of the housing 1 after the second charging head 11 is unfolded, thus affecting the folding of the second charging head 11.
[0030] In this embodiment, a storage box 20 is fixedly embedded on the right side of the housing 1. A sealing block 6 is slidably connected to the inner wall of the storage box 20. The storage box 20 can be used to store the data cable, so as to carry the data cable and connect the device to the power supply.
[0031] The working principle of this utility model is as follows:
[0032] In use, by pulling the square tube 9, the control seat 22 is moved. The control seat 22 moves along the direction of the slide groove 18 through the cooperation of the slider 24 and the slide groove 18. This causes the square tube 9 to push the through tube 10 up and down, thereby adjusting the height of the second charging head 11. Pressing the square tube 9 down causes the bottom end of the square tube 9 to push the control seat 22 to reset, thereby retracting the square tube 9 into the housing 1. Then, the through tube 10 and the second charging head 11 are pushed down, causing the second charging head 11 to enter the stepped groove 2. The device is then folded to prevent the second charging head 11 from protruding from the housing 1, making the device easy to carry and protecting the second charging head 11.
[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
