Description

Technical Field

[0001] This invention relates to the field of automotive heat dissipation technology, and more specifically to an automotive heat dissipation and cooling device based on solar power generation. Background Technology

[0002] Cars, as a convenient means of transportation, are widely used in daily life. However, in hot weather, when a car is parked outdoors for a period of time, the interior temperature rises. Because the interior is a closed environment, heat cannot dissipate, causing the temperature to rise even higher. Excessive interior temperature accelerates the aging of the interior materials and causes serious discomfort to occupants. Therefore, it is necessary to turn on the air conditioning to cool the interior before entering the vehicle. However, the car's air conditioning is powered by the engine. For traditional gasoline-powered vehicles, the initial cost of running the engine and air conditioning via fuel is too high, the process is time-consuming, and the environmental impact is poor. Therefore, this invention mainly addresses the above-mentioned technical problems. Summary of the Invention

[0003] To address the existing technical problems, this invention provides a solar-powered automotive cooling device to solve the problems of high cost and poor environmental performance caused by using fuel to drive the engine and air conditioning to cool the vehicle interior in the prior art.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0005] A solar-powered automotive cooling device includes a mounting base on the roof of the vehicle, on which an airbag assembly is connected.

[0006] The airbag assembly includes an airbag connected to the inner sides of the two side walls of the mounting base via connecting strips. When inflated, the airbag forms a flat arch shape, and a hot airflow channel is formed between its bottom and the mounting base. A flexible solar panel is provided on the top of the airbag for supplying power to electrical equipment.

[0007] The mounting base is equipped with an air outlet pipe and an electric telescopic rod. The lower end of the air outlet pipe is connected to the interior space of the vehicle, and the top of the air outlet pipe is provided with an elbow facing the hot airflow channel. The movable end of the electric telescopic rod is connected to a fan through a ball joint mechanism. The fan is used to provide the negative pressure environment required for the flow of hot air.

[0008] In the above technical solution, when the vehicle is parked outdoors in summer, the airbag assembly is opened to inflate the airbag. The inflated airbag is located on the top of the vehicle, which can block the sun from the vehicle top and reduce sun exposure. The deployed flexible solar panel absorbs solar energy to generate electricity to power electrical equipment. On the other hand, the electric telescopic rod and ball joint mechanism are activated to adjust the position and angle of the fan and turn on the fan. The hot air inside the vehicle is discharged through the hot air channel after entering the hot air flow channel under the negative pressure generated by the fan.

[0009] Preferably, a roller is provided inside the mounting base along its width direction, and a pull bar is provided at the bottom of the airbag. The lower end of the pull bar is connected to the roller, and the pull bar can be wound around the roller as the roller rotates.

[0010] Preferably, the mounting base has a receiving space for accommodating the deflated airbag assembly.

[0011] Preferably, the top of the mounting base is slidably provided with a cover plate, which is used to open or close the receiving space.

[0012] Preferably, the mounting base has symmetrical lead screw mechanisms on both side walls, and the two sides of the cover plate are respectively connected to the corresponding lead screw mechanisms. The lead screw mechanisms drive the cover plate to move back and forth, thereby opening or closing the accommodating space.

[0013] Preferably, the mounting base is equipped with an air pump, which is connected to the inner cavity of the airbag via an air pipe.

[0014] Preferably, the airbag has an air outlet at its tail, which is connected to a hot air flow channel.

[0015] Preferably, the inner cavity of the airbag is provided with longitudinal and transverse braces, the two ends of the longitudinal braces being connected to the top and bottom of the airbag respectively, and the two ends of the transverse braces being connected to the front and rear ends of the airbag respectively.

[0016] Preferably, the connecting strip is inclined downwards from front to back, so that the airbag presents an overall state of being higher in the front and lower in the back after inflation.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention uses an airbag to physically shield the roof after inflation and deployment, effectively blocking direct sunlight and reducing heat absorption at the source; at the same time, a fan creates a negative pressure environment inside the airbag assembly, drawing hot air from the vehicle through the exhaust pipe to the hot airflow channel for discharge, thereby effectively reducing the temperature inside the vehicle.

[0019] 2. The present invention has a flexible solar panel on the top of the airbag to convert solar energy into electrical energy to power electrical equipment. This design avoids the problems of traditional methods of starting the engine with fuel and cooling the air conditioner, which is both energy-saving and environmentally friendly as well as safe and reliable.

[0020] 3. The present invention sets longitudinal and transverse braces in the airbag cavity to limit the airbag expansion height after inflation, so that the airbag forms a flat arched streamline structure and is fixed by connecting strips on both sides. At the same time, the deflated airbag assembly is automatically rolled up and stored in the storage space of the mounting base by rollers, making the whole more flat and beautiful, and the stored airbag assembly will not increase additional wind resistance during driving.

[0036] As attached Figure 1 - Appendix Figure 11 The vehicle cooling device based on solar power generation includes a mounting base 1 on the roof of the vehicle, and an airbag assembly is connected to the mounting base 1.

[0037] The airbag assembly includes an airbag 22. The bottom two sides of the airbag 22 are connected to the inner sides of the two side walls of the mounting base 1 via connecting strips 21. The connecting strips 21 are inclined downwards from front to back, so that the airbag 22, when inflated, presents a front-high, back-low shape. An air pump 3 is mounted on the mounting base 1. The air pump 3 communicates with the inner cavity of the airbag 22 via an air pipe 31, inflating the inner cavity of the airbag 22. After inflation, the airbag 22 forms a flat, arched shape, and a hot airflow channel 26 is formed between its bottom and the mounting base 1.

[0038] The mounting base 1 is equipped with an air outlet pipe 4 and an electric telescopic rod 5. The lower end of the air outlet pipe 4 is connected to the interior space of the vehicle, and the top of the air outlet pipe 4 is provided with an elbow facing the hot airflow channel 26. Hot air from inside the vehicle enters the hot airflow channel 26 through the air outlet pipe 4. A one-way valve can also be provided in the air outlet pipe 4 to restrict the airflow direction so that it can only flow out of the vehicle and not flow from outside the vehicle to inside the vehicle. The movable end of the electric telescopic rod 5 is connected to the fan 7 through a ball joint mechanism 6. The electric telescopic rod 5 is set in the horizontal direction, and the ball joint mechanism 6 is used to adjust the angle and position of the fan 7. After the fan 7 is started, it can provide the negative pressure environment required for the flow of hot air.

[0039] A flexible solar panel 8 is provided on the top of the airbag 22. The output end of the flexible solar panel 8 is electrically connected to the storage battery. The electrical energy generated by the flexible solar panel 8 is stored in the storage battery (not shown in the figure). In this embodiment, the storage battery is electrically connected to the air pump 3, the electric telescopic rod 5, the fan 7, the drive part of the lead screw mechanism 11, and the roller motor to supply power to the electrical equipment, so that it is not necessary to supply power through the vehicle battery.

[0040] The airbag 22 has longitudinal braces 23 and transverse braces 24 distributed inside its cavity. The two ends of the longitudinal braces 23 are connected to the top and bottom of the airbag 22, respectively, and the two ends of the transverse braces 24 are connected to the front and rear ends of the airbag 22, respectively. When the airbag 22 is inflated, the longitudinal braces 23 and transverse braces 24 tighten and limit the inflation height of the airbag 22, making the airbag 22 flat and arched. The tail of the airbag 22 is provided with an air outlet 25, which is connected to the hot airflow channel 26.

[0041] The mounting base 1 has a roller 13 installed inside it along its width direction. The roller 13 is connected to the output end of the roller motor. The bottom of the airbag 22 is provided with a pull bar 27. The lower end of the pull bar 27 is connected to the roller 13, and the pull bar 27 can be wound around the roller 13 as the roller 13 rotates.

[0042] The mounting base 1 has a receiving space 10 for accommodating the deflated airbag assembly. The airbag 22 is equipped with an exhaust valve. After the vehicle interior has cooled down, the exhaust valve is opened to deflate the airbag 22. After deflation, the roller motor is activated, rotating to wind the pull strip 27 onto the roller 13, simultaneously retracting the airbag assembly into the receiving space 10 on the mounting base 1. The air pump 3 is also located within the receiving space 10, at its front end. The air pipe 31 is a flexible conduit, allowing it to be retracted into the receiving space 10 along with the airbag assembly after deflation.

[0043] A cover plate 12 is slidably provided on the top of the mounting base 1. The cover plate 12 is used to open or close the receiving space 10. Specifically, the sliding method of the cover plate 12 is as follows: lead screw mechanisms 11 are symmetrically provided on the two side walls of the mounting base 1. The two sides of the cover plate 12 are respectively connected to the corresponding lead screw mechanism 11. The lead screw mechanism 11 drives the cover plate 12 to move back and forth, thereby opening or closing the receiving space 10.

[0044] Under normal circumstances, the airbag assembly is housed in the receiving space 10 of the mounting base 1. When it is necessary to cool the interior of the vehicle, the screw mechanism 11 is activated to move the cover plate 12 to open the receiving space. The air pump 3 is activated to inflate the airbag 22. After the airbag 22 is fully inflated and deployed, the flexible solar panel 8 on its top absorbs solar energy to generate electricity, which is stored in the battery and supplies power to the electrical components. Then, the electric telescopic rod 5 and the ball joint mechanism 6 are activated to adjust the position and angle of the fan 7. The position and angle of the fan 7 should facilitate the airflow in the hot airflow channel 26 and then be discharged from the air outlet 25. After the adjustment is in place, the fan 7 is turned on, forming a negative pressure in the hot airflow channel 26, which facilitates the hot air in the vehicle to enter the hot airflow channel 26 from the air outlet pipe 4 and then be discharged from the air outlet 25.

[0045] The preferred embodiments of the present invention have been described above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
