Description

Mobile Electrical System

technical field

The present invention relates to a mobile device, and in particular to a mobile electrical system powered by solar panels.

Background technique

For a long time, if you want to use electrical equipment in outdoor activities (such as using a refrigerator to cool food or medical supplies), you often use an extension cord to connect the plug and the socket. However, many wilderness areas do not have any power sources available nearby, so extension cords are not useful, and in such cases, fuel-based generators such as gasoline or diesel generators that can generate their own electricity are often used to generate electricity. Electricity is used by power supply equipment.

However, when the fuel of this type of fuel-type generator is used up, it will not be able to continue to generate electricity, so this type of generator cannot achieve the function of continuous power supply for a long time. If the endurance of the fuel-type generator is to be increased, the user must carry extra fuel to supplement at any time. However, such a method will not only cause inconvenience to users, but may also bring potential dangers due to the flammability of the fuel.

In addition, fuel-type generators often produce quite high decibel noise when in use, and some fuel-type generators even emit black smoke during operation to pollute the air and the environment.

To sum up, how to provide a mobile, environmentally friendly and high-endurance power supply device is an urgent need.

Contents of the invention

In view of this, an object of the present invention is to provide a mobile electrical system, which uses solar panels to supply power, so it has the functions of mobility, environmental protection, and high endurance, and overcomes the hidden problems of the above-mentioned fuel-type generators. Contains problems and shortcomings.

Another object of the present invention is to provide a mobile electrical system that can be quickly assembled or disassembled, so as to facilitate users to quickly disassemble and assemble, thereby improving the mobility of the present invention.

In order to achieve the above object, according to an embodiment of the present invention, a mobile electrical system includes a base frame, electrical equipment, a bracket, and a solar panel. Electrical equipment is accommodated in the bottom frame. The bracket is connected to the chassis. The solar panel is arranged on the support to generate electricity and provide it to electrical equipment.

In one or more embodiments of the present invention, the above-mentioned mobile electrical system further includes a plurality of clips disposed on the bracket, and each clip has a clip bottom, a limiting piece, a clip side and a pressing hook. The limiting piece is arranged on one side of the bottom of the clip, so as to pass through a frame mounting hole of the solar panel to prevent the solar panel from moving. The side part of the clip is arranged on the other side of the bottom of the clip. The side part of the clip has elasticity so that when the solar panel is pressed down, it can bend outwards and when the solar panel is pressed down until its frame abuts against the bottom of the clip, it will spring back inward, thereby Press down on the sides of the solar panel frame. The pressing hook is arranged on the side of the clip away from the bottom of the clip, so as to tightly press the upper surface of the solar panel frame. The pressure hooks of any two opposite clips face each other, so as to facilitate the clamping of the solar panel.

Through the above technical means, the mobile electrical system disclosed in the present invention can not only use solar panels for power supply, but also use multiple elastic clips to quickly and conveniently disassemble and assemble solar panels, thus improving the mobility of the present invention. and convenience.

The above description is only used to illustrate the problem to be solved by the present invention, the technical means for solving the problem, and the effects thereof.
