Detailed Description

The present application will be described in detail below with reference to exemplary embodiments in the accompanying drawings. It should be understood, however, that this application may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the application to those skilled in the art.

Furthermore, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the figures, it is easy for a person skilled in the art to proceed with appropriate combination or deletion between these technical features (or equivalents thereof), thereby obtaining still further embodiments of the present application that may not be directly mentioned herein, without departing from the technical scope of the present application.

Fig. 1 is a schematic view of a solar charger 1 according to one embodiment of the present application, wherein the solar charger 1 is in an unfolded state. The solar charger 1 comprises two or more solar panels 100 in series, for example 8 solar panels 100 in series are shown in fig. 1. By connecting the solar panels 100 in series, the electric energy collected by each solar panel 100 is superimposed, so that a higher voltage can be output as a whole, for example, up to 8 volts can be generated per solar panel 100, and then 64 volts can be output as a whole. Fig. 5 shows a schematic diagram of the solar charger 1, it being seen that the solar charger 1 further comprises a voltage regulator 200 electrically connected to two or more solar panels 100 and an output 300 electrically connected to the voltage regulator 200. The voltage regulator 200 can regulate the voltage output by two or more solar panels 100 to a preset voltage of the output part 300, wherein the preset voltage is a voltage required for charging electric equipment (including an electric car, an electric bicycle, an electric scooter, an electric balance car, a notebook computer, a mobile phone and the like), so that the solar charger 1 can output higher direct current modulated by the voltage regulator to the electric equipment with corresponding voltage requirements.

Specifically, the output voltage of the two or more solar panels 100 is related to the illumination condition, and in the case that the illumination condition is good and the illumination is sufficient, the two or more solar panels 100 are operated normally, the output voltage thereof can reach substantially the maximum output voltage thereof, and the output voltage is higher than the preset voltage, at this time, the voltage step-down module 220 of the voltage regulator 200 is in an activated state, the voltage step-down module 220 can reduce the voltage output by the two or more solar panels 100 to the preset voltage, for example, the voltage of the solar panels connected in series is 64 volts, and the voltage can be adjusted to 48 volts, 36 volts, 24 volts, 18 volts, 12 volts, etc. by the voltage step-down module 220. It should be appreciated that although a few voltage values are shown here by way of example, the actual voltage may be higher than this during actual charging, for example, for a charging situation corresponding to a preset voltage of 36 volts, the voltage may also reach around 43 volts during actual charging. In an alternative embodiment, the voltage output by the two or more solar panels 100 may be lower than the preset voltage when, for example, in cloudy days, the illumination intensity is low (or when the required charging voltage of the powered device is high, which is originally higher than the maximum voltage that the two or more solar panels 100 can output), at which time the boost module 210 of the voltage regulator 200 is activated to boost the voltage output by the two or more solar panels 100 to the preset voltage.

Under such an arrangement, the solar charger described herein dynamically adjusts the output voltage of the solar charger through the voltage regulator, so that the solar charger can directly charge the voltage systems (12V, 18V, 24V, 36V, 48V, 60V, etc.) of conventional electric equipment, thereby improving the adaptability to different electric equipment, avoiding additional voltage adaptation devices and simplifying the charging operation steps.

Further implementations or refinements, improvements relating to the solar charger will be described by way of exemplary illustration below in order to further improve its operating efficiency, reliability or other improvements.

As fig. 3 shows the arrangement position of the output part 300, for example, the output part 300 may be disposed at the outer sides of the plurality of solar panels 100 in the folded state, and may be covered with the cover case 440 openable (e.g., in a zipper manner) to prevent dust intrusion or other damage when the solar charger 1 is not operated. The output part 300 includes an output interface 310, and the output part 300 is directly and electrically connected to the electric equipment via the output interface 310 and directly charges the electric equipment with a preset voltage, so as to realize direct point-to-point charging of higher direct current electric equipment (for example, more than 20V). Output interface 310 may include a DC interface, a USB interface, a TYPE-C interface, a QC3.0 fast charge interface, etc. suitable for various common voltage outputs. Fig. 2 shows a plurality of charging lines 500 leading from the output interface of the solar charger 1 for charging a plurality of consumers. In addition, the output portion 300 may further include a PD (Power Delivery protocol) module electrically connected to the output interface, so as to provide a high-Power (e.g., up to 100 watts) output scheme for dc electric devices (such as mobile phones, unmanned aerial vehicles, notebook computers, and rechargeable flashlights).

In an alternative embodiment, the output unit 300 may further include a voltage stabilizing output module for controlling the output voltage to be stable, so that a relatively stable voltage output can be maintained under different illumination conditions, so as to ensure continuous charging.

In a preferred embodiment, two or more solar panels 100 are foldably connected via a folding member 400. As shown in fig. 1 and 2, the folding member 400 may include, for example, a flexible fabric 410, and two or more (e.g., 8 are illustrated) solar panels 100 are laid at intervals and integrally laminated on the flexible fabric 410, and may be folded along the intervals therebetween. As in fig. 1 and 2, solar panels 100 are arranged in a row, and in other embodiments, a plurality of solar panels may be arranged in a plurality of rows. By means of the folding mode, portability of the solar charger is achieved while the high light receiving area of the solar charger is guaranteed. On this basis, the folding member 400 may further comprise handles 420 provided at edges of the flexible fabric 410, for example, at opposite short sides of the elongated flexible fabric 410 in fig. 1 and 2, so that when the solar panel 100 is folded into a box (see fig. 3 and 4), both handles 420 are at the same side of the box for a user to carry the solar charger 1. Furthermore, in other embodiments, the folding members 400 may also be hinges or other flexible connections connected between adjacent solar panels 100 to enable the solar panels 100 to be folded. As shown in fig. 3 and 4, the solar charger 1 further includes a locking belt 430 wound around the outside of the solar panel 100 in a folded state of the solar panel 100 to lock it. Through the foldable design of the solar panels 100, the solar panels 100 have large light receiving area when unfolded, improve the generated energy, obviously reduce the volume when folded, and are convenient to carry and store.

Under this kind of arrangement, according to this application effectively improved solar charger's generating efficiency to further improved its suitability and portability, greatly made things convenient for user's operation and use.

The above examples mainly illustrate the solar charger of the present application. Although only a few embodiments of the present application have been described, those of ordinary skill in the art will appreciate that the present application may be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the illustrated examples and embodiments are to be considered as illustrative and not restrictive, and the application is intended to cover various modifications and substitutions without departing from the spirit and scope of the technical solutions of the application.
