DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-Figure 2 , the present invention provides a technical solution: a vehicle-mounted air umbrella device, comprising a housing 1, a mounting opening 3 for matching with a luggage rack of a vehicle is arranged on one side of the housing 1;

[0050] The air outlet 4 is arranged on the other side surface of the housing 1, and a guide vane 5 is arranged inside the air outlet 4 for guiding the high-pressure airflow of the pressurized guide mechanism.

[0051] The pressurized flow guide mechanism is arranged in the shell 1, and the pressurized flow guide mechanism includes a main flow channel 103 which is small at both ends and high in the middle. Such a design can guide the airflow quickly. An airflow boosting structure is arranged in the main flow channel 103. One end of the main flow channel 103 is connected to the oblique flow guide channel 106, and the oblique flow guide channel 106 is connected to the horizontal flow guide channel 108. The horizontal flow guide channel 108 is connected to the air outlet 4. A connecting line 6 is arranged on the shell 1, and the connecting line 6 can be connected to the vehicle system and control the operation of the airflow boosting structure.

[0052] The vehicle system is connected to the vehicle's rain sensing sensor, door vibration sensor, car key and the car manufacturer's mobile phone APP respectively. At the same time, the vehicle system is also connected to the high-speed motor 116. The door vibration sensor is arranged in the outer handle or the inner handle of the door. The signal of the rain sensing sensor is combined with any signal from the door vibration sensor, the car key and the car manufacturer's mobile phone APP to intelligently control the high-speed motor 116.

[0053] First, the device is fixed on the luggage rack of the car and connected to the car system in the car's central control through the connecting line 6. When it rains, the rain sensor on the car detects rainfall information. When the user needs to enter the vehicle, the user senses the signal of the rain sensor through the car key, or the user touches the outside handle of the car, and the door vibration sensor detects the user's hand signal, or the remote control signal of the car company's mobile phone APP is used to run the high-speed motor 116, and the high-speed airflow is transported to the oblique guide channel 106 through the main guide channel 103, and then to the horizontal guide channel 108 through the oblique guide channel 106. The horizontal guide channel 108 transports the airflow to the air outlet 4, and guides the airflow through the guide blades 5. The high-speed airflow forms an air cover on the upper side of the door, which can effectively prevent rain and avoid the user from getting caught in the rain when entering the vehicle.

[0054] When the user needs to move from inside the car to outside the car, the car system can operate the high-speed motor 116 through the car computer central control or by pulling the door handle inside the car. The high-speed airflow is transported to the inclined guide channel 106 through the main guide channel 103, and then to the horizontal guide channel 108 through the inclined guide channel 106. The horizontal guide channel 108 transports the airflow to the air outlet 4, and the airflow is guided by the guide blades 5. The high-speed airflow forms an air cover on the upper side of the door, which can effectively prevent rain and avoid the user from getting caught in the rain when moving from inside the vehicle to outside the vehicle.

[0055] As a specific embodiment of this application, please refer to Figure 3 and Figure 4 The airflow boosting structure includes a main shaft 112, which is rotatably arranged in a mounting sleeve 113, and the mounting sleeve 113 is arranged in the main airflow channel 103.

Pressurization blades 104 arranged in a tower shape are arranged on the secondary shaft 105. The main shaft 112 and the secondary shaft 105 are connected through an acceleration transmission component. The external airflow is introduced into the main airflow channel 103 through the rotation of the fan blades 109. At the same time, the acceleration transmission component drives the secondary shaft 105 to rotate faster, and the airflow is spirally pressurized by the pressurization blades 104 to increase the conveying speed of the airflow.

The shaft 121 drives the acceleration gear 119 to rotate, and the rotation of the acceleration gear 119 drives the transmission gear 122 to accelerate the rotation, and the transmission gear 122 drives the auxiliary shaft 105 to accelerate the rotation. At this time, the auxiliary shaft 105 has the same rotation direction as the main shaft 112, and the auxiliary shaft 105 drives the pressure blades 104 to rotate. Since the pressure blades 104 are arranged in a tower shape, the airflow can be accelerated to flow in a vortex form. The high-speed vortex-form airflow is transported to the oblique guide channel 106 and the horizontal guide channel 108, and then discharged through the air outlet 4, which greatly increases the airflow speed and improves the rain protection effect.
