Description

 Portable solar charger

 The present invention relates to a charger, and more particularly to a portable solar charger that uses solar energy to generate electrical energy.

Background technique

 In general, many electronic products are mostly equipped with rechargeable rechargeable batteries for environmental protection purposes. When the rechargeable battery is out of power, it needs to be placed in a charger, and the conventional charger is a charging power source that is converted into a certain voltage level by the transformer, and then the rechargeable battery is charged.

 However, the user sometimes happens to be in an environment where it is difficult to find a socket that provides power, such as in a poor country or a barren mountain. At this time, the charger is similar to waste, which is inconvenient for the user.

 In this regard, there are many chargers that use solar power to solve the above problems. However, the solar panels and battery holders of these chargers are fixed on the charger, so once the solar panel and the battery holder are temporarily In the event of a failure, a situation in which the battery cannot be charged immediately occurs, and the user's appliances (such as a mobile phone, tablet, etc.) cannot be used.

 As mentioned above, since the faulty solar panel or battery holder cannot be directly replaced, the user usually has no choice but to relinquish the charger and add another new charger, which will increase. The user's financial burden, in addition, some of the parts of the discarded charger are still available, but they are forced to be discarded together, which is a waste of waste.

Summary of the invention The main object of the present invention is to provide a portable solar charger that can be carried around and that can be easily replaced at any time by the solar panel and the battery holder.

 To achieve the above object, the portable solar charger of the present invention comprises a body, a solar module and a battery holder. The main body includes a plurality of plate bodies and a sliding cover. The plate body defines a chamber. The plate body comprises a bottom plate, a front plate, a rear plate and two side plates. The bottom plate forms at least a part of the transparent portion. The two side plates are respectively disposed between the front plate and the rear plate, and the two side plates are respectively provided with a first track groove; wherein the sliding cover is slidably disposed on the two first track grooves, when When the slide cover is in a closed position, the slide cover is closed at the opening of the chamber; the battery holder is detachably disposed on the body; and the solar module is detachably received in the chamber and electrically Connecting the battery holder, the solar module includes at least one light absorbing surface facing the permeable portion of the bottom plate; wherein light energy can pass through the permeable portion from the external space and be absorbed by the absorbing surface The solar module converts the light energy into electrical energy and transmits the electrical energy to the battery holder.

 Thereby, the invention can be conveniently carried by the user and can be charged by using light energy anywhere, and can also slide the slider directly out at any time to quickly replace the solar module and directly replace the battery holder. Once one of the solar modules or battery holders fails, other unfaulted components can be retained and continue to be used, indirectly reducing the economic burden and environmental load for the user.

The two side walls 53 are respectively provided with one of the sliders 531, and the set of the limiting members 14 are provided with the two third track grooves 142. When the cover 5 is slidably disposed on the set of the limiting members 14, the The slider 531 of the two side walls is slidable along the two third track slots 142. The battery holder 2 passes through the opening and is received into the accommodating space 54 when the rear wall 52 of the cover touches the limit. In the case of the position member 14, the cover 5 is positioned on the set of the limit members 14, whereby the cover can provide good protection of the battery holder without being hit by foreign objects, and the cover can also be Transparent, allowing light energy to pass through the cover and further illuminate the light absorbing surface of the solar panel.

 In addition, the present invention may further include a fixing member for selectively fixing the body to any place where the light can be irradiated. Preferably, the fixing member is a suction cup 6, and the suction cup is disposed on the bottom plate 111. The user can use the suction cup 6 to adsorb the invention on the wall, door panel or window in the room, or when going out, the invention can be adsorbed on the window or other places where the vehicle can receive light. can.

Moreover, in order to improve the practicability of the present invention, the control circuit board 21 further includes an external power supply line 211, and the rear wall 52 defines a through hole 521. When the cover 5 is slidably disposed on the set of the limiting members 14, The external power line 211 passes through the through hole 521 (shown in FIG. 1 ). At this time, the external power line 211 can be externally connected to an electrical device 7 (for example, the flashlight shown in FIG. 2 is taken as an example) to enable the rechargeable battery. The power can be transmitted to the appliance 7, so that the appliance 7 has sufficient power to directly use or indirectly charge its internal rechargeable battery. Summarizing the above, the present invention is convenient for the user to carry and can use the solar energy to charge the rechargeable battery anytime and anywhere, and the user does not need to worry about not finding the socket for the electric power. Furthermore, the present invention can also be used by the user to replace the battery holder and the solar module at any time. Once one of the faults is broken, or when a different style of the battery holder is to be replaced, the slide cover and the cover can be quickly and smoothly slipped. Conveniently slipping out, the solar module can be directly taken out, and the battery holder can be slid out from the limiting member, and the new product can be replaced immediately, so that the user can use the light energy to charge immediately, and use It is not necessary for the entire charger to be discarded due to one of the faults, and it can be left as an unfaulted component, indirectly reducing the economic burden and the environmental load for the user, and also making full use of the unfaulted component, so the present invention does Very progressive.
