Description

Technical Field

[0001] This utility model relates to solar energy storage devices, and more particularly to solar energy storage devices for vehicle-mounted and outdoor applications. Background Technology

[0002] Sun protection for cars is a pressing need for many car owners. Especially in summer, when parked outdoors, sunlight causes the interior temperature to rise rapidly, sometimes exceeding 60 degrees Celsius. This high temperature and ultraviolet rays from the sun damage interior items and materials, accelerating their aging process. Furthermore, due to the high interior temperature, it takes a long time for the air conditioning to lower the cabin temperature to a comfortable level after the car is started. Currently, various sunshades are commonly used, utilizing reflective materials to reflect incident sunlight. However, their effectiveness is generally limited; incident light energy still remains inside the car through transmission, scattering, multiple reflections, and direct heating of the sunshade.

[0003] Furthermore, modern gasoline-powered vehicles have incorporated an increasing number of intelligent devices that still consume electricity even when parked, such as security monitoring equipment and intelligent sensing devices. Prolonged parking can cause battery depletion, and in severe cases, even prevent the vehicle from starting. Therefore, appropriately replenishing the vehicle battery can not only extend battery life but also improve vehicle reliability, especially when the car is parked for extended periods.

[0004] Utilizing solar energy technology to convert incident sunlight into electrical energy for storage can directly absorb most of the incident light energy, reducing the temperature rise inside the vehicle and improving sunshade effectiveness. It can also power onboard equipment and replenish the battery, making it a more environmentally friendly and effective solution for protecting cars from the sun. However, current solar energy storage products are relatively bulky due to the need to consider the energy storage requirements as backup power sources, making them unsuitable for the limited space under the windshield of a vehicle.

[0005] This utility model addresses market demand by proposing a portable, foldable vehicle-mounted solar panel. The device employs a two-layer flat structure; when parked, the solar panel is extended close to the windshield for efficient solar energy collection and storage; when driving, it can be folded into a flat device and fixed to the center console, still capable of collecting and storing incident solar energy. This utility model is applicable to various vehicle models. Combining modern solar technology, energy storage battery management, and user-friendly design, this utility model presents a highly efficient, convenient, and intelligent vehicle-mounted solar panel device that balances portability, aesthetics, and practicality, providing an innovative solution for new energy utilization.

The two are connected by two support rods and damping shafts at both ends. The solar panel can be opened, raised, and adjusted to any tilt angle by the support structure. A ring-shaped LED light is embedded on the back of the solar panel. The outer shell of the base is made of lightweight aluminum alloy and high-strength plastic, and a thin-film soft-pack lithium battery and a control board are installed inside, which are connected by a power cable. The front panel of the base is equipped with at least one USB power output port and at least one status indicator light. The top surface of the base is designed with metal heat dissipation grooves. The positions where the support rods are installed on both sides of the base are designed with recessed steps to accommodate the support rods and damping shafts when the solar panel and the base are closed, so that the back of the solar panel fits snugly against the top surface of the base.

[0007] The solar panel includes a high-efficiency monocrystalline silicon or flexible thin-film solar cell with an anti-reflective coating on its surface.

[0008] The control board is a PCB circuit board that integrates a main control processor, a lithium battery charging and discharging management circuit, a voltage conversion circuit, a maximum power point tracking circuit, a power output interface, and status indicator lights.

[0009] The support rod and damping shaft have internal connecting cables that enable electrical connection between the solar panel and the control board.

[0010] The solar panel further includes half-size extended solar panels on both sides; the solar panel and the extended solar panels on both sides are connected by a pivot structure.

[0011] The base is equipped with an anti-slip suction cup and a strong magnetic block at the bottom, and has a mounting screw hole in the center.

[0012] The vehicle-mounted solar cell proposed in this utility model can raise the solar panel close to the windshield when the vehicle is parked, achieving efficient solar energy collection and storage, thereby reducing the temperature rise inside the vehicle; when driving, it can be folded up into a flat device and placed on the center console, where it can also collect and store incident solar energy, reducing the load on the vehicle's air conditioning.

[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] This utility model proposes a vehicle-mounted solar cell, the external structure of which is as follows: Figure 1 As shown, this vehicle-mounted solar panel adopts a double-layer flat structure. The upper layer is a solar panel A1, which uses high-efficiency monocrystalline silicon or flexible thin-film solar cells to ensure maximum light energy conversion efficiency. The surface is coated with an anti-reflective coating to reduce energy loss and improve weather resistance. The lower layer is a base A2, whose outer shell is made of lightweight aluminum alloy and high-strength plastic to ensure durability and heat dissipation. Internally, it houses an energy storage battery and a control board. The energy storage battery uses a thin-film soft-pack lithium battery. The control board is a PCB circuit board integrating a main control processor, lithium battery charge / discharge management circuit, voltage conversion circuit, maximum power point tracking circuit, power output interface, and status indicator lights. The soft-pack lithium battery is connected to the control board via a power cable.

[0021] The solar panel A1 and the base A2 are connected by two support rods A3 and a damping shaft structure at both ends of the support rods. Figure 1As shown. The damping shaft structure is fixed to the back of the solar panel A1 and the base A2 respectively. The positions where the damping shaft structure is mounted on both sides of the base and the corresponding connecting rod sections are designed with recessed steps. This allows the connecting rod to retract into these recessed steps when the solar panel is retracted, ensuring a complete fit between the upper solar panel A1 and the base A2. The overall shape is flat, and its placement above the center console does not obstruct the driver's view. The damping shaft and support rod are hollow structures, with internal cables connecting the solar panel and the control board. Thus, using the support rod and the damping shafts at both ends, the solar panel A1 can be opened, raised, and adjusted to any tilt angle from the base A2, facilitating alignment with the car's windshield angle to optimize sunlight reception and improve charging efficiency.

[0022] The front view of the vehicle-mounted solar cell after the solar panel A1 is retracted is shown below. Figure 2 As shown, the front panel of the base A2 has at least one USB power output port A5 and several status indicator lights A6. The USB power output port includes a 5VDC port and a 12VDC port, used to output power to other electronic devices and car batteries. The upper part of the base A2 housing further includes a metal heat sink structure.

[0023] A ring-shaped LED light is embedded in the back of the solar panel A1, such as Figure 3 As shown. Therefore, the vehicle-mounted solar cell proposed in this utility model can also be used as emergency lighting during outdoor activities, and has multiple functions.

[0024] To increase the light-receiving area and improve the power of the solar cells, two half-size solar panels, A1-1 and A1-2, can be added to both ends of the existing solar panel via a rotating shaft structure. When retracted, these two extended solar panels overlap with the original solar panel A1. Figure 4 As shown, this design allows the solar cell to maintain a flat overall structure even after the addition of extended solar panels. In use, opening the two extended solar panels A1-1 and A1-2 doubles the light-receiving area.

[0025] Furthermore, the back of the base A2 is equipped with an anti-slip suction cup and a strong magnet, allowing the device to be easily attached to an empty space below the windshield of a car or to the roof. A standard gimbal mounting screw hole is also designed at the center of the back of the base A2, allowing the solar cell to be mounted on any common tripod, such as a camera / camcorder tripod or a telescope tripod, in outdoor scenarios. This design aims to leverage the portability of the solar cell to expand its application scenarios.

[0026] This utility model proposes a vehicle-mounted solar cell with a foldable two-layer flat structure. When parked, the solar panel is extended close to the windshield for efficient solar energy collection and storage, thereby reducing the temperature rise inside the vehicle. When driving, it can be folded up into a flat device and placed on the center console, where it can still collect and store incident solar energy, reducing the load on the vehicle's air conditioning. The vehicle-mounted solar cell can also be used for emergency lighting in outdoor scenarios, and to collect and provide DC power to smart devices using solar energy. It is a highly efficient, convenient, and multi-purpose solar cell device.
