[0003] The existing vehicle-mounted wind power generation device can not improve the wind speed at the position of the fan blade when in use, and the wind speed at the position of the fan blade cannot be improved in the case of low vehicle speed or weak wind speed, so that the wind turbine cannot generate enough electric energy. This means that the power demand of vehicle-mounted equipment during vehicle driving cannot be effectively met, which may result in insufficient battery endurance, and further improvement is needed, and therefore a vehicle-mounted wind power generation device is proposed. UTILITY MODEL CONTENTS

[0004] The main purpose of the utility model is to provide a kind of vehicle-mounted wind power generation device, which can effectively solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] A kind of vehicle-mounted wind power generation device, comprising frame, the front end of the frame is provided with a plurality of first through holes, the rear end of the frame is provided with a plurality of second through holes, the upper inner wall of the frame is installed with hollow cylinder, the lower inner wall rear portion of the frame is installed with power generation assembly, the inside of the hollow cylinder is installed with auxiliary component, the power generation assembly is located at the rear side of auxiliary component, and the auxiliary component is used to increase the wind speed at the power generation assembly.

[0007] Preferably, the auxiliary component includes a circular cylinder, the circular cylinder is installed on the inner cylindrical surface of the hollow cylinder, the rear end of the circular cylinder is installed with a circular truncated cone, the circular truncated cone is communicated with the circular cylinder, and the diameter of the inner wall surface of the rear side of the circular truncated cone is smaller than the diameter of the inner cylindrical surface of the circular cylinder.

[0008] Preferably, the inner cylindrical surface of the circular cylinder is installed with a screen in the front part.

[0009] Preferably, the upper inner wall middle part and the lower inner wall middle part of the circular cylinder are jointly installed with a fixing frame, the inside of the fixing frame is movably sleeved with a connecting shaft, the rear end of the connecting shaft is installed with a fourth fan blade, the front end of the connecting shaft is movably inserted into the front side of the screen and fixedly connected with a scraper, and the scraper is movably contacted with the screen.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting auxiliary components, the wind speed at the first, second, and third fan blades can be increased. When outside air enters the cylinder and enters the truncated cone, the airflow speed increases because the diameter of the opening on the left side of the truncated cone is small.

[0016] 2. By setting up a screen, large objects from the outside can be prevented from contacting the first, second, and third fan blades, reducing the possibility of damage to the first, second, and third fan blades and improving their service life. Furthermore, by setting up a fourth fan blade, connecting shaft, and scraper, the screen surface can be cleaned. When the vehicle body moves, the wind drives the fourth fan blade to rotate, and the fourth fan blade drives the scraper through the connecting shaft to remove debris, preventing debris from accumulating on the screen and affecting the wind speed, thus ensuring the normal power generation of the equipment.

[0027] like Figure 1 , Figure 2 Figure 5 and Figure 6 As shown,

[0028] Example 1

[0029] A vehicle-mounted wind power generation device includes a frame 2. The front end of the frame 2 has several first through holes 5, and the rear end of the frame 2 has several second through holes 6. A hollow cylinder 7 is installed on the upper inner wall of the frame 2, and a power generation component 4 is installed on the rear part of the lower inner wall of the frame 2. In use, the frame 2 is installed inside a vehicle body 1. The vehicle body 1 moves the frame 2, and outside air enters the hollow cylinder 7 through the first through holes 5, driving the blades of the power generation component 4 to rotate, generating mechanical energy, and then generating electrical energy to power the vehicle. However, at low vehicle speeds or weak wind speeds, the wind turbine may not generate enough electrical energy. This means that the vehicle's power demand for the onboard equipment cannot be effectively met during driving, potentially leading to insufficient battery range.

[0030] To address the aforementioned drawbacks, auxiliary components 8 are installed inside the hollow cylinder 7. The power generation assembly 4 is located behind the auxiliary components 8. The auxiliary components 8 are used to increase the wind speed at the power generation assembly 4. The auxiliary components 8 include a circular cylinder 82, which is installed on the inner cylindrical surface of the hollow cylinder 7. A frustum 81 is installed at the rear end of the circular cylinder 82, and the frustum 81 is connected to the circular cylinder 82. The diameter of the rear inner wall of the frustum 81 is smaller than the diameter of the inner cylindrical surface of the circular cylinder 82. When outside air enters the circular cylinder 82 and then the frustum 81, the airflow speed increases according to Bernoulli's principle because the diameter of the opening on the left side of the frustum 81 is smaller. This allows for a higher rotational speed at relatively low wind speeds, ensuring that the generator produces sufficient electrical energy, thereby increasing the electrical output and meeting the power demand of the vehicle's onboard equipment during driving, thus ensuring the vehicle's range.

[0031] In addition, to prevent large objects from coming into contact with the power generation component 4, a screen 17 is installed in front of the inner cylindrical face of the cylindrical tube 82. The screen 17 can block large objects, reducing the possibility of damage to the power generation component 4 and improving its service life.

[0032] Based on the above solution, since debris will adhere to the screen 17, affecting wind speed and power generation, in order to ensure normal power generation, a fixed frame 15 is installed in the middle of the upper inner wall and the middle of the lower inner wall of the cylindrical cylinder 82. A connecting shaft 18 is movably sleeved inside the fixed frame 15. A fourth fan blade 16 is installed at the rear end of the connecting shaft 18. The front end of the connecting shaft 18 is movably inserted into the front side of the screen 17 and fixedly connected to a scraper 19. The scraper 19 is in contact with the screen 17. When the vehicle body 1 moves, the wind drives the fourth fan blade 16 to rotate automatically. The fourth fan blade 16 drives the scraper 19 to rotate through the connecting shaft 18, scraping away the debris on the surface of the screen 17, avoiding the accumulation of debris on the screen 17 and affecting the wind speed, thus ensuring the normal power generation of the equipment.

[0033] The frame 2 is equipped with a storage battery 3, which is used to store electrical energy. The electrical energy generated by the power generation component 4 can be converted into direct current by a rectifier and stored in the storage battery 3.

[0034] Specifically: The power generation component 4 includes a first generator 41, which is fixed on the upper wall of the frame 2. The output end of the first generator 41 is fixed with a first fan blade 42. The first fan blade 42 is vertically arranged to facilitate receiving wind power from any direction. The first fan blade 42 is located on the rear side of the truncated cone 81. The wind power drives the first fan blade 42 to rotate, which in turn drives the internal components of the first generator 41 to rotate, generating electricity.

[0035] Example 2

[0036] like Figure 3 As shown, the difference from Embodiment 1 is that the power generation component 4 is provided in two sets, and the hollow cylinder 7 and its internal components are provided in two sets. The power generation component 4 includes a second generator 43, which is fixed on the upper wall of the frame 2. The output end of the second generator 43 is fixed with a second fan blade 44. The second fan blade 44 is located on the rear side of the frustum 81. The second fan blade 44 is a wind turbine, which can effectively capture wind energy and extract more energy from low wind speeds.

[0037] Example 3

[0038] like Figure 4 As shown, the difference from Embodiment 1 is that the power generation component 4 includes a third generator 45, which is fixed on the upper wall of the frame 2. The output end of the third generator 45 is fixed with a third fan blade 46. The third fan blade 46 is horizontally arranged, which is convenient for stable wind areas and can make full use of the directionality of the wind. The third fan blade 46 is located on the rear side of the truncated cone 81 and is located at the vehicle chassis.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
