Description

Technical Field

[0001] This invention relates to the field of automotive cooling, and more specifically, to an automatic cooling device and system for automotive interiors. Background Technology

[0002] In summer, cars exposed to direct sunlight experience a rapid increase in interior temperature, causing discomfort for passengers and leading to issues such as interior aging, air pollution, and safety hazards. Current solutions include passive heat insulation methods like sunshades and reflectors, but their effectiveness is limited. Some active cooling devices, such as small solar fans, are typically placed directly on the dashboard. These solar panels are small, inefficient, and limited by their installation location within the car, they don't receive optimal sunlight, resulting in weak airflow and inadequate cooling. Furthermore, wired connections to bring external solar power into the vehicle usually require drilling holes in the car's exterior for the power cables, leading to compromised sealing and increased wear on the wiring. Therefore, there is an urgent need for a non-contact, highly efficient, and easy-to-install automatic car cooling solution.

[0003] This invention aims to overcome the shortcomings of existing technologies and provide an automatic solar-powered cooling system for automobiles based on wireless power supply technology. This system places a high-power solar panel in the optimal sunlight location outside the vehicle and uses wireless power supply technology (such as magnetic resonance wireless power transfer technology) to transmit energy contactlessly into the vehicle to drive a high-power cooling device, thereby achieving efficient and convenient active cooling of the vehicle interior. Based on this, this application proposes an automatic cooling device and system for automobile interiors. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cooling device and system for automobiles. This system places a high-power solar panel in the best sunlight position outside the vehicle and uses wireless power supply technology to transmit energy to the vehicle interior without contact, thereby driving a high-power cooling device and achieving efficient and convenient active cooling of the vehicle interior.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: An automatic cooling device and system for automobiles includes an energy emitting unit located outside the vehicle, an energy receiving unit located inside the vehicle, and a cooling unit located inside the vehicle. The energy emission unit includes a solar panel for converting light energy into electrical energy, an energy conversion and control module connected to the output end of the solar panel, a high-frequency inverter circuit connected to the output end of the energy conversion and control module, and an emission coil A connected to the output end of the high-frequency inverter circuit for generating an alternating magnetic field. The energy receiving unit includes a receiving coil B for coupling with the transmitting coil to receive electrical energy, a rectifier and voltage regulator circuit connected to the output terminal of the receiving coil B, and an energy storage device connected to the output terminal of the rectifier and voltage regulator circuit. The cooling unit includes a cooling execution device connected to the output end of the energy storage device. The energy storage device includes multiple energy storage elements, which are independent of each other and can be freely switched. They are used to store the electrical energy provided by the energy receiving unit and to power the cooling execution device, respectively, so as to avoid accidents caused by simultaneous charging and discharging of a single energy storage element or to shorten the life of the energy storage element. The bottom of the solar panel is also fixedly installed with a bracket, and the bottom of the bracket is connected to a detachable adsorption fixing mechanism, which is used to fix the solar panel to the roof of the vehicle. As a preferred technical solution of this application, the energy transmitting unit and the energy receiving unit adopt wireless power supply technology that allows energy to penetrate the car shell, including but not limited to magnetic resonance wireless power supply technology and electromagnetic induction wireless power supply technology, and the cooling execution device is a fan, air conditioner or other cooling equipment driven by electric energy.

[0006] As a preferred technical solution of this application, the card holder includes a fixed plate, the bottom of the fixed plate is fixedly connected to a card slot, and the side wall of the fixed plate is also fixedly connected to an alignment block.

[0007] As a preferred technical solution of this application, a fixing bolt is inserted into the side wall of the card holder, and one end of the fixing bolt protruding from the card holder is fixedly connected to the solar panel.

[0008] As a preferred technical solution of this application, the adsorption and fixing mechanism includes an assembly base, and the side wall of the assembly base is provided with an alignment groove that is adapted to the alignment block.

[0009] As a preferred technical solution of this application, the side wall of the assembly base is fixedly connected to a support, and the inner side wall of the support is slidably connected to a locking tooth, which engages and is fixed with the locking groove.

[0010] As a preferred technical solution of this application, the bottom of the mounting base is fixedly connected to an adjustable suction cup, which can be adsorbed and fixed to the roof of the vehicle.

[0011] As a preferred technical solution of this application, a resistance spring is fixedly engaged on the side wall of the tooth, and one end of the resistance spring is fixedly engaged with the support. When the tooth loses its squeezing force, it can automatically reset and be inserted into the slot.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In the scheme of this application: High-efficiency energy harvesting: Solar panels are placed outside the vehicle, and the area and installation location can be selected as needed (such as the roof) to obtain maximum light intensity and power generation efficiency, which is far superior to miniature solar panels placed inside the vehicle.

[0013] Contactless energy transfer: Using wireless power supply technology, energy can be transmitted through the car's outer shell (such as car windows or roof sheet metal), eliminating the need for drilling holes and wiring in the car body. This completely solves problems related to sealing, leakage, and aesthetics, and installation and disassembly are extremely convenient.

[0014] Intelligent and efficient: Built-in MPPT control circuit maximizes the output power of the solar panel.

[0015] Highly practical: The system can power more powerful cooling devices (such as powerful fans or small semiconductor air conditioners), resulting in significant cooling effects and truly realizing effective active temperature regulation of the enclosed vehicle cabin using clean energy.
