DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] like Figures 1 to 7 As shown, this embodiment provides a smart umbrella, comprising: a top cover 1, a turntable 5 rotatably matched with the top cover 1, a foldable umbrella frame 2, a flying device 3, and a connecting rod 4 connecting the flying device 3 and the top cover 1. The top of the top cover 1 is provided with a cavity 6 with an opening facing upward; the turntable 5 is rotatably matched with the top cover 1 under the driving action of a motor (not shown in the figure), and the motor is installed in the cavity 6.

[0035] The foldable umbrella frame 2 includes a plurality of umbrella frames 22 and an umbrella surface 21 connected to the plurality of umbrella frames 22. The plurality of umbrella frames 22 are evenly arranged along the circumferential direction of the top cover 1, and the top end of each umbrella frame 22 is hinged to the top cover 1; each umbrella frame 22 includes a plurality of hollow rods, and two adjacent hollow rods are hingedly connected. A thin rope (not shown in the figure) is inserted into each umbrella frame 22, and the thin rope passes through the umbrella frame 22, and the bottom end is fixedly connected to the end of the umbrella frame 22, and the top end is fixedly connected to the rotating disk 1. More specifically, a rotating shaft 10 is fixedly connected downwardly at the bottom of the rotating disk 1, and the rotating shaft 10 is fixedly connected to the output shaft 8 of the motor; a plurality of connecting rods 11 are also fixedly connected between the bottom of the rotating disk 1 and the rotating shaft 10, and the plurality of connecting rods 11 correspond to the plurality of umbrella frames 22 one by one, and the top ends of the plurality of thin ropes are fixedly connected to the corresponding connecting rods 11.

[0036] Each of the umbrella frames 22 comprises a plurality of hollow rods, and two adjacent hollow rods are hingedly connected via a connecting joint 222; the connecting joint 222 comprises a first connecting tube 2221 and a second connecting tube 2222, the first connecting tube 2221 is fixedly connected to one of the hollow rods, the second connecting tube 2222 is fixedly connected to the other hollow rod, the first connecting tube 2221 is provided with a first extension plate, the second joint is provided with a second extension plate, the first extension plate is provided with a first hinge hole, the second extension plate is provided with a second hinge hole, the first hinge hole and the second hinge hole are hingedly connected via a hinge column 2224; one end of the hinge column 2224 is provided with a flange, the hinge column 2224 is inserted into the first hinge hole and the second hinge hole, and the other end is fixed by an annular stopper 2225. An elastic member 2223 is also fixedly connected between the backs of the first connecting tube 2221 and the second connecting tube 2222.

[0037] When the motor drives the turntable 5 to rotate clockwise after receiving the attitude adjustment instruction from the control system, the rotating column 10 and the connecting rod 11 are driven to rotate a certain angle, thereby overcoming the restoring force of the elastic member 2223, pulling the thin rope upward, and the umbrella frame 22 is opened under the pulling action of the thin rope; when the motor drives the turntable 5 to rotate counterclockwise, the umbrella frame is folded and retracted under the contraction action of the thin rope and the restoring force of the elastic member. Therefore, the smart umbrella of the present invention can realize the automatic folding and opening of the umbrella body.

[0038] The flying device 3 is used to control the suspension and following of the smart umbrella. The flying device includes a chassis 31, a plurality of rotors 32 and a control system 33 mounted on the chassis 31, a sensor part and a camera module. The plurality of rotors 32 are evenly arranged along the circumferential direction of the chassis 31, and each of the rotors 32 is driven to rotate by a motor 35, and each of the motors 35 is electrically connected to the control system 33. The rotors 32 can be set to four or six. Each of the rotors 32 is set to a propeller, and the posture of the smart umbrella canopy can be adjusted by rotating the rotors 32.

[0039] like Fig. 9 As shown, the motor 35 drives the rotor 32 to rotate to generate lift and fly. When the sum of the lifts of the four propellers is equal to the total weight of the parachute body, the lift of the parachute body is balanced with the gravity, and the parachute body can be suspended in the air.

[0040] As the rotor 32 rotates, it also applies a reaction force (reaction torque) to the motor 35, causing the motor 35 to rotate in the opposite direction. Therefore, in order to prevent the parachute from spinning, the two adjacent propellers of the four propellers of the quadrotor 32 rotate in opposite directions. The rotation direction of the rotors M1 and M3 is counterclockwise, and the rotation direction of the rotors M2 and M4 is clockwise. When flying, the counterclockwise reaction force (reaction torque) generated by M2 and M4 and the clockwise reaction force (reaction torque) generated by M1 and M3 offset each other, and the parachute fuselage can remain stable, thereby avoiding spinning and achieving smooth flight.

[0041] When the parachute needs to be raised, the four propellers will accelerate their rotation at the same time, the lift will increase, and the parachute will rise. When the parachute needs to be lowered, the four propellers will reduce their rotation speed at the same time, and the parachute will also descend. When the rotation speeds of the motors 35 are the same, the anti-torque of the parachute is offset and no rotation will occur. However, when the parachute needs to rotate in situ, by utilizing this anti-torque, the rotation speeds of the two clockwise rotating motors 35 M2 and M4 increase, and the rotation speeds of the two counterclockwise rotating motors 35 M1 and M3 decrease. Due to the influence of the anti-torque, the parachute will rotate counterclockwise.

[0042] When it is necessary to move forward in a certain direction, the propellers of the M3 and M4 motors will increase the speed, while the propellers of the M1 and M2 motors 35 will reduce the speed. Since the lift at the rear of the parachute is greater than that at the front of the parachute, the attitude of the parachute will tilt forward.

[0043] Looking straight from the side when tilted, the lift generated by the propeller not only offsets the weight of the parachute in the vertical direction, but also has a component in the horizontal direction. This component gives the parachute horizontal acceleration, allowing the parachute to fly forward.

[0044] When the M1 and M2 motors accelerate and the M3 and M4 motors decelerate, the parachute will tilt backwards and fly backwards. When the M1 and M4 motors accelerate and the M2 and M3 motors decelerate, the parachute will tilt left and fly left; when the M2 and M3 motors accelerate and the M1 and M4 motors decelerate, the parachute will tilt right and fly right.

[0045] Therefore, in the present invention, the control system controls the rotation direction and rotation speed of the multiple different rotors 32 to achieve the adjustment of the parachute posture and the flight of the parachute.

[0046] like Figure 5 As shown, the sensing part includes a photosensor 13 and a temperature sensor 12, a gyroscope, an acceleration sensor and a barometer (not shown in the figure) fixedly mounted on the top cover 1.

[0047] The light sensor 13 and the temperature sensor 12 are arranged at intervals along the circumference of the top cover 1, and are used to sense the direction and temperature of sunlight respectively. The barometer is used to measure the current atmospheric pressure and obtain the altitude information of the aircraft; the gyroscope and the acceleration sensor are used to measure the angular velocity and acceleration of the parachute in three-dimensional space respectively, and thus calculate the posture of the object.

[0048] The photosensor 13, temperature sensor 12, barometer, gyroscope and acceleration sensor are all electrically connected to the control system 33, and the collected signals are transmitted to the control system 33. The control system 33 controls the rotation of the plurality of propellers 32 according to the collected signals, thereby controlling the posture of the umbrella body to achieve the best umbrella tilt angle for sunshade and windproof.

[0049] The camera module includes a camera 9 fixedly mounted at the bottom of the chassis, the camera 9 is used to capture human body information and transmit the human body information to the control system 33, and the control system 33 controls the smart umbrella to follow the human body. Specifically, the camera 9 can be a 3D camera, the 3D camera captures the human body, and sends the captured depth data and color data to the control system 33, the control system 33 records the characteristic values ​​and position information of the human body, and the 3D camera builds a spatial coordinate system of the surrounding environment, the control system 33 calculates the center coordinates of the human body according to the spatial coordinates and the points mapped to the human body by the 3D camera; the control system 33 calculates the distance from the human body according to the center coordinates of the human body, and determines the speed of following the human body according to the distance. In order to improve the problem of dynamic response lag, after collecting the position data of the person, the fuzzy PID advance correction composite algorithm is used to control the motor, thereby improving the dynamic response lag, improving the position control accuracy, and further controlling the position of the umbrella body to achieve the purpose of following. For example, when the control system 33 obtains the center coordinates of the human body according to the 3D camera 9 and calculates that the distance between the human body and the center coordinates exceeds the set value, the control system 33 sends an attitude adjustment instruction to the drive motor, and the drive motor 35 controls the flight of the parachute according to the rotation speed and rotation direction of the different rotors 32. If the calculated distance between the human body and the human body does not exceed the set value, the control system does not send an attitude adjustment instruction to the drive motor 35, and the parachute continues to maintain the current attitude and speed for flight.

[0050] In the initial state, a command for opening and raising the umbrella is sent to the wireless receiving module in the control system 33 through the handheld terminal. The wireless receiving module controls the opening of the folding umbrella frame and controls the rotation of the rotor motor 35 to drive the umbrella to rise to a preset height.

[0051] Then, the temperature sensor 12, the light sensor 13 and the barometer installed on the parachute detect the temperature, the intensity and direction of the light and the height from the ground in real time, and measure the angular velocity and acceleration of the parachute in three-dimensional space in real time according to the gyroscope and the acceleration sensor, obtain the current posture of the parachute, and send the detected data to the control system 33, which fuses the monitored data and sends the parachute posture adjustment instruction to the drive motor 35 of the rotor 32, and controls the posture of the parachute by controlling the rotation speed and direction of the multiple rotors, so that the parachute is adjusted to a suitable height and tilt angle. At the same time, the 3D camera detects the distance between the human body and the parachute in real time, and controls the parachute to follow.

[0052] Furthermore, in order to protect the flying device 3, the smart umbrella further includes a protection cage 34, the flying device 3 is fixedly installed in the protection cage 34, the top of the connecting rod 4 passes through the protection cage 34 and is fixedly connected to the top cover 1; the chassis 31 is fixedly installed at the bottom of the protection cage 34, the control system 33 is installed at the center of the chassis 31 and protected in the shell, and the top of the shell is fixedly connected to the connecting rod 4. The connecting rod 4 is set as a hollow round rod, and the hollow round rod is used to place the cable for data transmission.

[0053] like Figure 8 As shown, a plurality of magnets 14 are fixedly mounted along the circumferential direction at the bottom of the chassis 31, and the plurality of magnets 14 correspond to the plurality of umbrella frames 22 one by one, and the magnets 14 are used to adsorb the umbrella frames 22 when folding. When the motor drives the turntable 5 to rotate clockwise, the umbrella frames 22 are opened under the pulling action of the thin rope to overcome the adsorption force of the magnets 14; when the motor drives the turntable 5 to rotate counterclockwise, the umbrella frames 22 are folded and gathered under the contraction action of the thin rope and the adsorption action of the magnets 14, thereby realizing automatic folding and opening.

[0054] In order to maintain a stable matching relationship between the turntable 5 and the top cover 1 and to limit the rotation angle, an arc-shaped groove 7 is opened at the bottom of the cavity 5 along the circumferential direction, and a limiting column (not shown in the figure) matching with the groove 7 is provided at the bottom of the turntable 5. The limiting column is inserted in the groove 7 and slides along the groove 7 when the turntable 5 rotates.

[0055] In order to make the umbrella body also have the function of night lighting, a lighting lamp (not shown in the figure) is fixedly installed at the bottom of the chassis 1.

[0056] Therefore, the smart umbrella provided by the present invention can realize automatic folding of the umbrella body, hovering in the air, automatic adjustment and following of the posture, thereby improving the intelligence of the umbrella body, freeing the hands of the human body, and facilitating use.

[0057] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
