Description

Technical Field

[0001] This utility model relates to the technical field of power bank charging equipment, specifically to a solar charging panel for power banks. Background Technology

[0002] Photovoltaic power generation is based on the photovoltaic effect of semiconductors. When sunlight shines on a photovoltaic cell, electrons in the cell absorb photon energy and generate electron-hole pairs. Under the influence of the electric field inside the cell, electrons and holes move to the two ends of the cell respectively, forming an electric current, thus directly converting light energy into electrical energy. Mountain climbers or cyclists often take advantage of the lightweight nature of photovoltaic panels to carry small photovoltaic panels to charge their personal devices.

[0003] Currently, power banks typically use USB connections for charging. However, if a solar panel is directly connected to a power bank via USB, the connection may easily break due to shaking during movement, affecting charging efficiency and user experience.

[0004] Therefore, this application proposes a solar charging panel for power banks to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that solar panels and power banks are prone to detachment after being connected via USB, and to provide a solar charging panel for power banks that offers a stable connection and is suitable for sports scenarios.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A solar charging panel for a power bank includes a solar panel and a voltage regulator. A cloth sheet is fixedly connected to the back of the solar panel. The voltage regulator is connected to the cloth sheet. A wire is connected to the voltage regulator. One end of the wire is connected to a USB connector. The solar panel, voltage regulator, wire, and USB connector are electrically connected. The USB connector includes a housing. A mating tongue is connected inside the housing. An extrusion plate is embedded between the mating tongue and the housing. A bolt is threaded onto the upper part of the extrusion plate. The lower end of the bolt is in movable contact with the housing. One end of the wire is fixedly connected to the housing, and the wire is electrically connected to the mating tongue.

[0008] In a preferred embodiment, the mating tongue includes a spring; a contact plate is fixedly connected to the lower part of the spring; the contact plate is electrically connected to a wire; the upper end of the spring is fixedly connected to the outer shell; and a guide plate is fixedly connected to the back of the spring.

[0009] In a preferred embodiment, the extrusion plate includes a nut; a pull plate is fixedly connected to the lower end of the nut; the pull plate slides through the outer shell; and an extrusion plate is fixedly connected to the lower end of the pull plate.

[0010] In a preferred embodiment, the bolt includes a knob; the lower end of the knob is fixedly connected to a bolt body; the bolt body is threaded inside a nut; and the lower end of the bolt body is in movable contact with the outer casing.

[0011] In a preferred embodiment, the outer periphery of the knob is provided with anti-slip texture.

[0012] In a preferred embodiment, the conductor is U-shaped.

[0013] In a preferred embodiment, a cord loop is fixedly connected to the lower end of the fabric piece.

[0014] Due to the application of the above technical solution, the beneficial effects of this application compared with the prior art are as follows:

[0015] 1. Insert the outer casing into the target power bank, tighten the bolts, and the bolts will exert upward force on the compression plate. The compression plate will then press the connector tongue against the USB connector tongue of the power bank's port, thus fixing the USB connector to the power bank. This significantly improves the stability between the device and the power bank and effectively prevents it from falling off during movement.

[0016] 2. When the extrusion plate moves upward, it acts on the guide plate, which in turn drives the spring to press against the mating tongue inside the target USB port, further ensuring a tight connection between the mating tongue and the target port.

[0017] 3. Rotating the bolts can drive the pressing plate to rise and fall via the nut and pull plate, making it easy to control the tightness of the mating tongue and allowing for flexible operation.

[0018] 4. The anti-slip texture on the outer edge of the knob increases friction and makes it easy to turn; the U-shaped cable adapts to the bend of the bag opening, making it easy to hang the solar panel on the outside of the backpack to receive sunlight; the rope loop can be connected to the backpack strap through the rope, enhancing the installation stability of the solar panel.

[0032] Example 1

[0033] Appendix Figure 1 and 2 A solar charging panel for a power bank includes a solar panel 6 and a voltage regulator. A cloth sheet 1 is fixedly connected to the back of the solar panel 6, and the voltage regulator is connected to the cloth sheet 1. A wire 7 is connected to the voltage regulator, and one end of the wire 7 is connected to a USB connector 2. The solar panel 6, voltage regulator, wire 7, and USB connector 2 are electrically connected. The USB connector 2 includes a housing 21, and a mating tongue 3 is connected inside the housing 21. A pressing plate 4 is embedded between the mating tongue 3 and the housing 21. A bolt 5 is threaded on the upper part of the pressing plate 4, and the lower end of the bolt 5 is in movable contact with the housing 21. One end of the wire 7 is fixedly connected to the housing 21, and the wire 7 is electrically connected to the mating tongue 3. The housing 21 is inserted into the target power bank, and then the bolt 5 is tightened. The bolt 5 acts upward on the pressing plate 4, and the pressing plate 4 presses the mating tongue 3, pressing the mating tongue 3 tightly onto the USB mating tongue of the power bank's socket, thus fixing the USB connector 2 to the target power bank and improving the stability between the device and the target power bank.

[0034] As attached Figure 2 and 3 As shown, the mating tongue 3 includes a spring piece 31, with a contact piece 33 fixedly connected to the lower part of the spring piece 31. The contact piece 33 is electrically connected to the wire 7. The upper end of the spring piece 31 is fixedly connected to the outer shell 21. A guide plate 32 is fixedly connected to the back of the spring piece 31. When the pressing piece 4 moves upward, the pressing piece 4 acts on the guide plate 32, causing the guide plate 32 to act on the spring piece 31, pressing the spring piece 31 against the mating tongue inside the target USB port.

[0035] like Figure 2 and 4 As shown, the extrusion plate 4 includes a nut 43, and a pull plate 41 is fixedly connected to the lower end of the nut 43. The pull plate 41 slides through the outer shell 21, and an extrusion plate 42 is fixedly connected to the lower end of the pull plate 41. Rotating the bolt 5 causes the bolt 5 to act upward on the nut 43, which in turn acts upward on the pull plate 41, which in turn acts upward on the extrusion plate 42, causing the extrusion plate 42 to press the mating tongue 3. Conversely, rotating the bolt 5 releases the mating tongue 3.

[0036] like Figure 2 and 5 As shown, the bolt 5 includes a knob 51, and the lower end of the knob 51 is fixedly connected to the bolt body 52. ​​The bolt body 52 is threaded inside the nut 43, and the lower end of the bolt body 52 is in movable contact with the outer shell 21. Turning the knob 51 causes the bolt body 52 to rotate. The bolt body 52 spirals along the inside of the nut 43, thereby causing the bolt body 52 to drive the extrusion plate 4 to rise. Conversely, turning the knob 51 causes the bolt 5 to loosen the extrusion plate 4.

[0037] like Figure 5 As shown, the outer periphery of the knob 51 is provided with anti-slip texture; the anti-slip texture is used to increase the friction between the knob 51 and the hand.

[0038] like Figure 1 As shown, the wire 7 is U-shaped; after placing the target power bank in the bag, the solar panel 6 is hung outside the bag, and the wire 7 is used to fit the opening of the bag.

[0039] like Figure 1 As shown, a rope loop 8 is fixedly connected to the lower end of the fabric piece 1; the rope is tied between the rope loop 8 and the strap of the target backpack to increase the stability of the fabric piece 1 and the solar panel 6.

[0040] Working principle: Insert the outer shell 21 into the target power bank, then tighten the bolt 5. The bolt 5 acts upward on the extrusion plate 4, which in turn presses the connector tongue 3 against the USB connector tongue of the power bank's port, thus fixing the USB connector 2 to the target power bank and ensuring the stability between the device and the target power bank.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
