The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 13, the present embodiment discloses a vehicle-mounted flying umbrella, which comprises an umbrella body assembly 100 and a driving assembly 200, wherein the driving assembly 200 is connected with the umbrella body assembly 100 and is used for driving the umbrella body assembly 100 to rotate.

The umbrella body assembly 100 comprises a first umbrella body 110 and a second umbrella body 120 which are coaxially arranged at intervals, and a cavity 130 for air to flow is formed between the first umbrella body 110 and the second umbrella body 120. Alternatively, the first umbrella body 110 can be disk-shaped, the second umbrella body 120 can be disk-shaped, and the first umbrella body 110 and the second umbrella body 120 can be spaced apart a distance such that an annular cavity 130 is formed therebetween, and gas can flow through the cavity 130 as the umbrella body assembly 100 rotates. The first umbrella body 110 is provided with an air inlet 111, the air inlet 111 is communicated with the cavity 130, and when the umbrella body assembly 100 rotates, air can enter the cavity 130 through the air inlet 111 and flow in the cavity 130. Alternatively, the gas inlet 111 may be opened in the middle region of the first umbrella body 110, so that the gas enters the cavity 130 from the middle of the first umbrella body 110, and in addition, one gas inlet 111 or a plurality of gas inlets 111 may be opened on the first umbrella body 110, so as to be adaptively selected according to actual situations. The chamber 130 has an air outlet 140 disposed at an edge of the umbrella body assembly 100 such that air within the chamber 130 can be exhausted through the air outlet 140. Alternatively, the air outlets 140 may be formed at the edge of the umbrella body assembly 100, so that air can be exhausted from the edge of the umbrella body assembly 100, and thus the rain water around the umbrella body assembly 100 can be blown by the air to change the falling direction of the rain water around the umbrella body assembly 100.

In order to make the air enter the cavity 130 and be discharged, in the embodiment of the present invention, at least one of the first umbrella body 110 and the second umbrella body 120 is provided with a blade, and the blade is located in the cavity 130, so that when the umbrella body assembly 100 rotates, the blade rotates along with the rotation, and can push the air in the cavity 130 to be discharged outwards through the air outlet 140, so that a certain vacuum degree is formed in the cavity 130 instantaneously, and at this time, the external air flows into the cavity 130 through the air inlet 111. Therefore, when the umbrella body assembly 100 rotates, the air outside the cavity 130 continuously enters the cavity 130 through the air inlet 111, flows into the cavity 130 to the air outlet 140, and is finally discharged from the air outlet 140. Since the gas discharged through the gas outlet 140 has a high speed, it blows the rainwater around the umbrella body, so that the rainwater changes the falling direction.

In order to suspend the vehicle-mounted flight umbrella in the air and blow the surrounding rainwater, in the embodiment of the present application, the air outlet 140 is designed such that the air outlet 140 is inclined from the middle to the edge of the umbrella body assembly 100 toward the direction away from the first umbrella body 110, that is, the air outlet 140 is inclined downward when the vehicle-mounted flight umbrella is in a use state. In this way, the air discharged through the air outlet 140 flows in an obliquely downward direction around the umbrella body assembly 100, so that a gas flow barrier P for blocking rainwater is formed around the umbrella body assembly 100, as shown in fig. 14. During the flow of the air, it may create a first force component directed vertically downward and a second force component directed away from the umbrella body assembly 100 on rain around the umbrella body assembly 100. According to the principle of acting force and reacting force, the umbrella body assembly 100 generates reacting force in the direction opposite to the first acting component force, that is, the umbrella body assembly 100 generates lifting force, and the lifting force overcomes the gravity of the vehicle-mounted flying umbrella (the impact of rainwater can be ignored or the impact of rainwater can be considered in the design), so that the whole vehicle-mounted flying umbrella can be suspended in the air, and the vehicle-mounted flying umbrella is ensured to be positioned above a user. Under the effect of second action component, the rainwater can move towards the direction that deviates from umbrella body subassembly 100, and meanwhile, the rainwater is vertical to move down under the action of gravity to make rainwater top-down move towards the direction of keeping away from umbrella body subassembly 100, and then make the user that is located on-vehicle flight umbrella below avoid drenching.

Compared with a folding umbrella, the vehicle-mounted flying umbrella in the embodiment of the present application is not held by hand, but suspended in the air through the rotation of the umbrella body assembly 100, and kept above the user, and forms the airflow barrier P above the user, so that the rainwater above the user is blown to the periphery of the vehicle-mounted flying umbrella and falls from the periphery of the user, and the effect of shielding the rainwater can be further achieved. Because on-vehicle flight umbrella is located the user top, and forms air current barrier P around the on-vehicle flight umbrella to form the large tracts of land effect of sheltering from in user top, and the rainwater can produce the direction that deviates from on-vehicle flight umbrella and the acceleration that deviates from user's direction under the blowing effect of umbrella body subassembly 100, thereby played the better effect of drenching of preventing.

Referring to fig. 3 to 5, in some embodiments, the first umbrella body 110 is a circular disk body, and a first inclined surface 113 is formed at a region of the circular disk body near an edge thereof, thereby forming a groove at one side of the first umbrella body 110. A concave groove 112 is formed in the central region of the circular disk body, and the concave groove 112 is concave from the bottom surface of the groove toward the inside of the groove, that is, the opening of the concave groove 112 faces opposite to the opening of the groove. Meanwhile, a plurality of air inlets 111 are formed on the bottom surface of the recess groove 112, so that the external air can enter the cavity 130 from the middle of the first umbrella body 110. Alternatively, the first inclined surface 113 may be an inclined plane or an inclined arc surface. In addition, the first umbrella body 110 can be integrally formed and manufactured in an integral forming mode, so that the manufacturing period can be shortened, and the manufacturing cost can be reduced.

With continued reference to fig. 3-5, in some embodiments, the second umbrella body 120 is a circular disc body formed with a second inclined surface 121. Alternatively, the second inclined surface 121 may be an inclined plane or an inclined arc surface. In addition, the second umbrella body 120 can be integrally formed and manufactured in an integrally forming manner, so that the manufacturing period can be shortened and the manufacturing cost can be reduced.

Based on the above arrangement, when the first umbrella body 110 and the second umbrella body 120 are assembled, the second umbrella body 120 is arranged at the inner side of the first umbrella body 110, that is, the inclination direction of the first inclined surface 113 is consistent with the inclination direction of the second inclined surface 121, so that a cavity 130 arranged obliquely is formed between the first umbrella body 110 and the second umbrella body 120, so as to dredge the gas through the cavity 130.

Referring to fig. 3 and 4, in order to enhance the blowing effect of the umbrella assembly 100, a plurality of first blades 114 are provided in the embodiment of the present application on the surface of the first umbrella 110 facing the second umbrella 120. Alternatively, the first blades 114 may be disposed obliquely, and the first blades 114 may be planar blades or cambered blades, in this embodiment, the shape, number, disposition position, and disposition manner of the first blades 114 are not limited, as long as the first umbrella body 110 can rotate while the gas can flow from the middle to the edge.

Similarly, a plurality of second blades 122 are provided on the surface of the second umbrella 120 facing the first umbrella 110. Alternatively, the second blades 122 may be obliquely disposed, and the second blades 122 may be planar blades or cambered blades, in this embodiment, the shape, number, disposition position, and disposition manner of the second blades 122 are not limited, as long as the second umbrella 120 can rotate while the gas can flow from the middle to the edge.

Based on the above arrangement, in the present embodiment, the blades are simultaneously provided on the surfaces of the first umbrella body 110 and the second umbrella body 120 facing each other, that is, the plurality of first blades 114 are provided on the surface of the first umbrella body 110 facing the second umbrella body 120, and the plurality of second blades 122 are provided on the surface of the second umbrella body 120 facing the first umbrella body 110. Thus, when the umbrella body assembly 100 rotates, the first blade 114 and the second blade 122 can push the gas in the cavity 130, so that the gas in the cavity 130 flows out quickly, a certain vacuum degree is generated in the cavity 130 instantaneously, and the gas can be ensured to flow into the cavity 130 and flow out of the cavity 130.

Referring to fig. 4, 5, 11, and 12, in order to drive the umbrella assembly 100 to rotate, in the present embodiment, the driving assembly 200 includes a first driving element 210 and a second driving element 220 coaxially disposed, wherein the first driving element 210 is connected to the first umbrella body 110, the second driving element 220 is connected to the second umbrella body 120, the first driving element 210 is configured to drive the first umbrella body 110 to rotate, and the second driving element 220 is configured to drive the second umbrella body 120 to rotate.

It is also possible that the driving assembly 200 further comprises an integrated motor including two rotors and a common stator, wherein when the integrated motor is powered on, the common stator can interact with the two rotors simultaneously, so as to rotate the two rotors simultaneously, and at this time, one of the rotors is connected to the first umbrella body 110, and the other rotor is connected to the second umbrella body 120, so as to drive the first umbrella body 110 and the second umbrella body 120 to rotate respectively. In the embodiment of the present application, the specific form of the driving assembly 200 is not limited.

It should be noted here that the rotation directions of the first umbrella body 110 and the second umbrella body 120 may be the same or opposite, and the rotation directions of the blades on the two umbrella bodies are adapted to each other, in short, when the umbrella body assembly 100 rotates, both the first umbrella body 110 and the second umbrella body 120 can blow air from the middle to the edge of the umbrella body assembly 100.

In order to provide power for the driving assembly 200, the onboard flight umbrella in the embodiment of the present application further includes a power supply assembly 300 disposed on the driving assembly 200, wherein the power supply assembly 300 is used for supplying power to the driving assembly 200. Alternatively, the power supply assembly 300 may include a storage battery, through which electric energy may be stored, and when it is required to use the vehicle-mounted flying umbrella, the electric energy may be released to the driving assembly 200, so that the driving assembly 200 operates, and the driving assembly 200 drives the umbrella body assembly 100 to rotate, so as to implement a rainproof function.

Referring to fig. 4 and 5, in some implementations, the power supply assembly 300 includes a housing 310 and a battery module 320 disposed in the housing 310, the battery module 320 being movable relative to the housing 310 to balance the on-board flying umbrella by changing the position of the battery module 320 in the housing 310, thereby tilting the on-board flying umbrella, and at the same time, moving the on-board flying umbrella in a horizontal direction in order to adjust the on-board flying umbrella to restore to a balanced state, thereby allowing the center of mass of the battery module 320 to continue to be on the same vertical axis as the center of mass of the on-board flying umbrella. Under the condition that the mass center of the battery module 320 and the mass center of the onboard flight umbrella are located on the same vertical axis, the onboard flight umbrella is kept still in the horizontal direction, and under the condition that the mass center of the battery module 320 deviates from the vertical axis where the mass center of the onboard flight umbrella is located, the onboard flight umbrella moves in the horizontal direction.

Referring to fig. 8 and 9, in order to realize the movement of the battery module 320 in the housing 310, in the embodiment of the present application, a first magnetic member 410 is disposed on an inner side surface of the housing 310, and correspondingly, a second magnetic member 420 is disposed on an outer side wall of the battery module 320, and the first magnetic member 410 and the second magnetic member 420 can interact with each other, so as to drive the battery module 320 to move relative to the housing 310. Alternatively, four first magnetic members 410 are disposed at intervals along the circumferential direction of the casing 310 on the inner side surface of the casing 310, the first magnetic members 410 may be electromagnets, and the second magnetic members 420 may be permanent magnets, and when the electromagnets are disposed, the polarities of the electromagnets are opposite to those of the permanent magnets, and when the electromagnets are powered on, an attraction effect may be generated between the electromagnets and the permanent magnets to drive the permanent magnets to move. Of course, the polarity of the electromagnet may be the same as that of the permanent magnet, and in this case, when the electromagnet is energized, the permanent magnet may be driven to move by repulsive interaction with the permanent magnet. In some embodiments, the magnetic force of each first magnetic member 410 acting on the second magnetic member 420 can be adjusted by adjusting the magnitude of the magnetic force, so that the position of the battery module 320 in the housing 310 can be adjusted as desired, and the center of mass of the battery module 320 can be correspondingly changed.

In the embodiment of the application, the operating principle that the vehicle-mounted flying umbrella moves horizontally by adjusting the mass center is as follows: when the vehicle-mounted flying umbrella is suspended in the air in a static way, the lifting force generated by the rotation of the umbrella body assembly 100 is approximately equal to the integral gravity of the vehicle-mounted flying umbrella, and at the moment, the mass center of the battery module 320 and the integral mass center of the vehicle-mounted flying umbrella are positioned on the same vertical axis; then, the power on the first magnetic member 410 is changed, the magnetic force between the first magnetic member 410 and the second magnetic member 420 is adjusted, so that the battery module 320 connected with the second magnetic member 420 is driven to move in the housing 310, and the position of the battery module 320 in the housing 310, that is, the mass center of the battery module 320 is changed, so that the mass center of the battery module 320 and the mass center of the whole vehicle-mounted flight umbrella are no longer on the same vertical axis, and a torque relative to the whole mass center of the vehicle-mounted flight umbrella is generated. Assuming that the torque causes the onboard flying umbrella to generate a yaw angle α, there is W = F sin α, where W is the translational force that the torque causes the onboard flying umbrella to generate, the translational force being in the horizontal direction, and F is the lifting force generated by the rotation of the umbrella body assembly 100. Thus, under the action of the horizontal force W, the vehicle-mounted flying umbrella moves along the horizontal direction. When the vehicle-mounted flying umbrella moves to a specified position, the power-on condition of the first magnetic piece 410 is adjusted, the first magnetic piece 410 interacts with the second magnetic piece 420, the battery module 320 is driven to move, the mass center of the battery module 320 returns to the same vertical axis with the whole mass center of the vehicle-mounted flying umbrella, and at the moment, the vehicle-mounted flying umbrella restores to a balanced state and is suspended in the air again to be static.

Based on the above setting, can make on-vehicle flight umbrella move on the horizontal direction through the position relation between the holistic barycenter of adjusting battery module 320 and on-vehicle flight umbrella, promptly, power supply unit 300 in the embodiment of this application has played the effect of rudder to change on-vehicle flight umbrella position on the horizontal direction, establish the basis for on-vehicle flight umbrella adapts to the user and removes.

Alternatively, the control system 500 may be an ECU that mainly functions to receive, process and send signals, thereby performing a control function during the whole working process of the in-vehicle flying umbrella.

Alternatively, the control system 500 can control the rotation speed, rotation direction, etc. of the first driving element 210 and the second driving element 220 to ensure that the total torque generated by the first umbrella body 110 driven by the first driving element 210 and the second umbrella body 120 driven by the second driving element 220 is zero, thereby ensuring that the umbrella body assembly 100, and thus the entire vehicle-mounted flight umbrella, does not tilt or deflect.

With continued reference to fig. 15, in order to enable the on-board flying umbrella to follow the user, the on-board flying umbrella in the embodiment of the present application further includes an identification sensing system 600, and the identification sensing system 600 is in signal connection with the control system 500, so that signal interaction can be performed between the two systems to identify and control the posture of the on-board flying umbrella. The identification sensing system 600 includes at least one of a camera 610, an ultrasonic distance meter, and a laser radar, but the identification manner is not limited in the embodiment of the present application. Optionally, a camera 610 may be provided at least at the bottom of the on-board flying umbrella, which is primarily used to detect the surrounding environment, the user, etc., which provides signals for user's attitude adjustments for tracking, height from rain, etc.

In addition, camera 610 can also shoot the user to with shoot information transmission to control system 500, obtain characteristics such as user's height, size after control system 500 handles, thereby adjust on-vehicle flight umbrella for user's height and position through control system 500 control, with furthest guarantee to the user hide the rain function. In addition, the camera 610 can also shoot the surrounding environment to prevent the normal work of the vehicle-mounted flying umbrella from being influenced by the fact that the vehicle-mounted flying umbrella touches other obstacles.
