Description

Technical Field

[0001] The present invention relates to the field of energy storage devices, and particularly to a lightweight energy storage device. Background Art

[0002] In the context of the global strong advocacy for green energy and the increasingly popular concept of portable travel, lightweight outdoor portable energy storage devices are highly favored because they can provide convenient power support for various electrical devices. Many outdoor portable energy storage devices are equipped with a solar power generation function, using solar energy, a clean and renewable energy source, to supplement electrical energy for the device at any time and place, greatly expanding the usage scenarios and battery life. However, the solar power generation device needs sufficient light conditions to work efficiently, which also makes it extremely easy for the temperature to rise due to light radiation during operation, thereby having many adverse effects on the performance of the energy storage device.

[0003] Since lead-acid batteries have a larger volume at the same power, lithium-ion batteries are more convenient to carry. Because the solar power generation device is exposed to sunlight for a long time during operation and is prone to heating up, and lithium-ion batteries have relatively strict requirements for the working temperature, there is a risk of overheating in a high-temperature environment. This will not only accelerate the attenuation of the battery capacity and significantly shorten the battery life, but may also cause serious safety accidents such as fire and explosion, greatly reducing the reliability and practicality of the energy storage device. Summary of the Invention

[0004] In order to solve the above problems in the prior art, the present invention proposes a lightweight energy storage device that can improve the heat dissipation efficiency.

[0005] To solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0006] As Figure 1 shown, a lightweight energy storage device includes a housing, an energy storage unit, a photovoltaic panel, a controller, and a cooling fan; the energy storage unit is disposed inside the housing, the photovoltaic panel is disposed on the top of the housing, the photovoltaic panel is electrically connected to the energy storage unit, and the housing is provided with a plurality of charging interfaces connecting the energy storage unit. The charging interfaces include a plurality of standard electrical interfaces for connecting external electrical appliances;

[0007] One end of the housing is provided with the cooling fan, and the side surface of the housing is provided with heat dissipation holes;

[0008] A number of temperature sensors are evenly arranged on the inner wall of the housing to detect the temperature inside the housing. The temperature sensors are electrically connected to the controller, and the controller is electrically connected to the cooling fan. The controller adjusts the rotation speed of the cooling fan according to the temperature measured by the temperature sensors. When the temperature measured by the temperature sensors is higher than the preset value, the controller starts the cooling fan. The cooling fan blows air into the housing, and blows out the air with a higher temperature inside the housing through the heat dissipation holes, accelerating the air flow rate inside the housing and improving the heat dissipation efficiency. A dust-proof filter screen is provided at the air inlet of the cooling fan.

[0009] Furthermore, threaded telescopic rods are provided at the four corners of the housing. The push rods of the threaded telescopic rods extend to the top of the housing. The photovoltaic panel provided on the top of the housing is installed on the tops of the push rods of the four threaded telescopic rods. The housing is provided with a start button. When the start button is pressed, the four threaded telescopic rods push the photovoltaic panel upwards, separating the photovoltaic panel from the housing, and preventing the photovoltaic panel that directly receives light from generating heat and affecting the temperature rise of the housing.

[0010] Furthermore, the photovoltaic panel is connected to the top of the push rod of the threaded telescopic rod through a spring to accommodate the errors of the four threaded telescopic rods.

[0011] Furthermore, grooves are provided on both sides of the housing, and the heat dissipation holes are provided at the inner top of the grooves to prevent foreign objects from falling into the heat dissipation holes.

[0012] Furthermore, two photovoltaic panels are connected to both sides of the top of the housing through rotating pairs. Both sides of the photovoltaic panel are connected to support rods through rotating pairs. Threaded holes are provided at the ends of the support rods, and screws are installed in the threaded holes. The other ends of the screws passing through the threaded holes can be stuck in the grooves to fix the angle of the photovoltaic panel. When not in use, the photovoltaic panel can be attached to the side of the housing. When in use, the photovoltaic panel can be unfolded to increase the light-receiving area, improving the power generation efficiency and avoiding the photovoltaic panel being close to the housing and affecting heat dissipation.

[0013] Further, it also includes a raised bottom case. The raised bottom case includes a bottom plate, side plates, and an embedding strip. The side plates are vertically provided on both sides of the bottom plate. The side plates are attached to both side surfaces of the case where the grooves are provided. The embedding strip is provided at the top inside the side plates. The embedding strip can be embedded into the grooves. By changing the grooves into which the embedding strip is embedded, the installation position of the raised bottom case can be adjusted, and the height of the case can be changed. The raised bottom case raises the case and separates the case from the ground, preventing the case from being affected by the heat dissipated from the ground, increasing the bottom surface heat dissipation area, and improving the heat dissipation efficiency. When not in use, the embedding strip is embedded into the grooves at the highest position. At this time, the bottom plate is attached to the bottom of the case, and the side plates block the grooves. At this time, the two photovoltaic panels connected to the top of the case through a rotating pair can be fixed to both sides of the case through the support rods and the screws.

[0014] Further, a heat dissipation fan is provided on one side of the raised bottom case. The heat dissipation fan is electrically connected to the controller and is powered by the energy storage unit. When the temperature measured by the temperature sensor is higher than the preset value, the controller starts the heat dissipation fan to accelerate the air flow rate at the bottom of the case and improve the heat dissipation efficiency.

[0015] Further, a power display screen is provided on the outer surface of the case. The power display screen is electrically connected to the controller.

[0016] Further, a handle is provided at one end of the case for convenient handling.

[0017] The beneficial effects of a lightweight energy storage device of the present invention are as follows: The heat dissipation fan at one end of the case is linked with the temperature sensors evenly distributed on the inner wall. The controller adjusts the fan speed according to the temperature and discharges the hot air through the heat dissipation holes on the side. The threaded telescopic rods at the four corners of the case can push the photovoltaic panels upward, separating the photovoltaic panels from the case to prevent the heat generated by the photovoltaic panels due to light from being conducted to the case. The rotating photovoltaic panels on both sides of the top of the case can be unfolded, and the screws at the ends of the support rods are clamped into the grooves to fix the angles, increasing the light receiving area while preventing heat dissipation from being affected by fitting the case. The embedding strip of the raised bottom case can adjust the installation position, raise the case and separate it from the ground, expand the bottom heat dissipation area, and can be attached to the case for storage when not in use. The heat dissipation fan on one side of the raised bottom case is controlled by the controller to start and stop according to the temperature, accelerating the air flow at the bottom of the case and improving the overall heat dissipation performance.

[0018] The raised bottom case adjusts the installation height through the embedding strip, separates the case from the ground, expands the bottom surface heat dissipation area, and can be attached to the case for storage when not in use.

[0019] The heat dissipation fan of the bottom case is controlled by the controller according to the temperature, strengthening the air flow at the bottom and improving the overall heat dissipation efficiency.

[0020] The power display light gives real-time feedback on the energy storage status, and the handle design facilitates the handling of the device. Description of the Drawings
