Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically a portable power adapter. Background Technology

[0002] A power adapter is a power conversion device for small portable electronic devices and appliances. It is generally composed of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board. It is an electronic device that converts alternating current (AC) into direct current (DC) and stabilizes the output voltage and current. Power adapters are widely used in various electronic devices, such as audio equipment, projectors, monitors, and computers. Its main function is to convert unstable AC power into stable DC power for the devices to use. This not only protects the devices from voltage fluctuations but also ensures the normal operation of the devices and extends their service life.

[0003] A portable power adapter is disclosed on the Chinese Patent Network (patent publication number CN220797249U), including an adapter body, a rotating shaft, a limiting component, pins, a rotating shaft, a telescopic rod, a protective cover, a connecting block, and two bases. By setting up the bases, rotating shaft, protective groove, telescopic rod, and protective cover, when the power adapter needs to be used, rotating the pins allows the limiting component to limit the base, sliding the protective cover so that it is located below the pins, and inserting the locking block into the corresponding slot, thus preventing the protective cover from affecting the use of the power adapter. When not in use, rotating the base allows the pins to be located in the protective groove, rotating and sliding the protective cover so that it covers the pins, and inserting the locking block into the corresponding slot, thus protecting the pins from dust accumulation and deformation when not in use.

[0004] The aforementioned power adapter provides protection and dust protection for the adapter body structure through the protective cover and the rotating structure of the plug, making it easy to carry and use. However, the adapter is bulky during carrying and takes up a lot of space when stored in a pocket. In addition, the power cord connected with the adapter is also difficult to store, and the cord often gets tangled and wrapped in the pocket, which is very inconvenient. Therefore, we propose a portable power adapter. Utility Model Content

[0012] Furthermore, the clamping frame includes a shell back plate, and a torsion spring shaft is connected to the outer wall of the shell back plate. A clamping plate is connected to one side of the torsion spring shaft, and an anti-slip layer is attached to the outer wall of the clamping plate. The shell back plate is connected to the outer wall of the other side of the shell frame.

[0013] Furthermore, the clamping plate forms an elastic rotation structure with the outer wall of one side of the shell back plate through a torsion spring shaft, and the shell back plate is fixedly connected to the outer wall of the shell frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The power adapter can be stored by rotating the plug connected to the rotating base through the storage slot on one side of the housing frame. At the same time, the winding slots around the edge of the housing frame can be used to wind the connected power cord into shape, so that it is placed in the winding slot. With the slider sliding and engaging with the slot, the wound power cord can be kept stable and avoid tangling and knotting during storage and carrying. This provides convenience and stability while reducing the overall space occupied by the adapter.

[0016] The power adapter has a circuit board inside its cavity. The circuit board carries components and is electrically connected to the power cord and plug to ensure the normal operation of the adapter. Meanwhile, the rubber pads attached to the inner wall of the cavity provide cushioning protection for the circuit board, further improving the safety of the adapter during use.

[0017] This power adapter can be held in place by a clamp connected to a torsion spring shaft on the back of the casing. The anti-slip layer on the surface of the clamp is made of soft rubber. Pressing one end of the clamp will open it for holding, making it easy to operate. The adapter can be held and stored using the clamp to prevent loss and make it more convenient to carry.

A rotating seat 103 is provided inside the storage groove 102, and a plug 104 is connected to one end of the rotating seat 103. A winding groove 105 is provided on the four periphery of the outer shell frame 101, and a power cord 106 is connected to the inner wall of the winding groove 105. A slider 107 is provided on one side of the winding groove 105, and a slot 108 is engaged at one end of the slider 107.

[0029] To facilitate the carrying, storage, and use of this power adapter, such as Figure 1-2 As shown, this power adapter can be rotated and stored through the storage slot 102 on one side of the housing frame 101, and the plug 104 connected to the rotating base 103 can be rotated and stored. At the same time, the winding slots 105 around the edge of the housing frame 101 can be used to wind the connected power cord 106 into shape, so that it is placed in the winding slot 105. With the slider 107 sliding and engaging with the slot 108, the wound power cord 106 can be kept stable and avoid tangling and knotting of the cord during storage and carrying. This provides convenience and stability for carrying while reducing the overall space occupied by the adapter.

[0030] like Figure 3 As shown, the equipment compartment 2 includes an inner cavity 201, and a buckle plate 202 is engaged on one side of the inner cavity 201. A circuit board 203 is disposed inside the inner cavity 201, and rubber pads 204 are attached around the circuit board 203.

The shell back plate 301 is connected to the outer wall of the other side of the shell frame 101.

[0033] Finally, for even greater convenience in carrying and using, such as Figure 3-4 As shown, this power adapter can be clamped by the clamping plate 303 connected to the torsion spring shaft 302 on the back panel 301. The anti-slip layer 304 on the surface of the clamping plate 303 is made of soft rubber material and can be opened by pressing one end of the clamping plate 303. The operation is convenient. The adapter can be clamped and stored by the clamping plate 303 to prevent loss and make it more convenient to carry.

[0034] In summary, when using this power adapter, the user can first fold and rotate the plug 104 along the connection direction of the rotating base 103, so that the rotating base 103 and the plug 104 are rotated into the storage slot 102, while the power cord 106 is wound and stored along the winding slot 105 until the end of the power cord 106 is stored in the winding slot 105. At this time, the user presses the slider 107, so that the slider 107 slides along the shell back plate 301 into the winding slot 105 and is inserted and fixed into the slot 108 on the other side of the winding slot 105, thus limiting the winding power cord 106, thereby completing the folding and storage process. Then, the user can directly carry and store this adapter in a pocket or other environment, or press the anti-slip layer 304 of the clamp 303 to open the clamp 303 and use the elastic structure to clamp it in a belt or other position, saving space and maintaining stability when carrying it.
