[0002] The IoT-based wearable micro-drone system is a portable multi-rotor micro-drone control device. Firefighters or rescue personnel can wear the device to enter dangerous environments, launch the micro-drone in real time to obtain images of the front, and achieve data sharing and remote control.

[0003] Patent CN207976769U discloses a drone control device, including a control handle. A display screen frame is movably connected to the back of the control handle, and two control sticks are movably mounted on the top of the control handle. Evenly distributed elastic cotton is movably connected to both sides of the control handle. Rubber shock-absorbing plates are fixedly connected to the opposite sides of the elastic cotton on both sides. Evenly distributed rubber sleeves are fixedly connected to the opposite sides of the two rubber shock-absorbing plates. Evenly distributed inner springs are fixedly connected to the opposite sides of the two rubber shock-absorbing plates. This control device effectively avoids the problem of the control handle breaking or internal electronic components being damaged due to accidental collisions, thus preventing impact on the drone in flight, extending the service life of the control handle and the drone, and avoiding unnecessary property damage.

[0004] However, current drone control devices have the following problems: due to the small size of the main body of the wearable micro drone based on the Internet of Things, the user needs to manually pick up the main body of the micro drone to take off, which is very cumbersome and inconvenient, thus causing the problem of inconvenient take-off of wearable micro drones. Therefore, we propose an Internet of Things-based wearable micro drone system. Summary of the Invention

The outer wall of the micro-drone is fixedly connected to the inner wall of the U-shaped strip. The micro-drone body is placed in the middle of the top surface of the concave shell. The shaft of the micro servo motor drives the screw to rotate forward. The screw rotates forward in the U-shaped frame. Under the constraint of the sliding groove of the concave shell, the screw drives the triangular ring to move backward. The triangular ring drives the U-shaped strip to move backward. The U-shaped strip drives the sliding cover to move backward. The sliding cover moves backward away from the front cover and away from the top of the micro-drone body. The micro-drone body flies upward. The front and rear modules one and the left and right modules two send commands to the mobile app software. The commands are transmitted to the data processing center (local or cloud) via the communication module. A three-dimensional image is formed in the mobile app software. After the mobile app software optimizes the commands, control commands are generated and sent to the micro-drone body. The micro-drone body performs tasks (such as flight and shooting) and transmits the data back. The sliding cover is used to protect the micro-drone body.

[0007] According to the above technical solution, a front cover is fixed to the top of the front of the concave shell, and a hook is fixed to both sides of the front of the concave shell. The hook is used to connect a hanging rope, so that the user can conveniently carry the drone equipment.

[0008] According to the above technical solution, a sliding shaft is provided on both the left and right sides of the sliding cover. The sliding shaft of the sliding cover is slidably connected to the inner wall of the sliding groove of the concave shell. The ends of the sliding shafts of the sliding cover that are far apart from each other are fixedly connected to the inner wall of the U-shaped strip.

[0010] According to the above technical solution, a clamping device is provided on the top surface of the sliding cover, the clamping device is used to clamp the mobile phone, and an anti-loosening device is provided on the front side of the clamping device, the anti-loosening device is used to fasten the sliding cover and the front cover.

[0011] According to the above technical solution, the clamping device includes: a U-shaped plate fixed in the middle of the top surface of the sliding cover; a heat-conducting plate fixed in the middle of the top surface of the U-shaped plate; a circular tube fixed at the top of the inside of the U-shaped plate; sliding columns slidably mounted on the inner wall of the circular tube in pairs, with a spring at the end of the sliding columns that are close to each other; and an L-shaped plate fixed at the end of the sliding columns that are far apart from each other. The U-shaped plate drives the circular tube to move backward, the circular tube drives the sliding columns to move backward, the sliding columns drive the springs to move backward, and the sliding columns drive the L-shaped plate to move backward. When the mobile phone is placed in the middle of the L-shaped plate, under the action of the squeezing force, the sliding columns move to both sides in the circular tube, the springs are stretched, and the L-shaped plate clamps the mobile phone by the elastic force of the stretched springs.

[0012] According to the above technical solution, two short columns are fixed on the front of the U-shaped plate, and a connecting plate is fixed on the front of each short column. A horizontal plate is fixed on the top of the back of the connecting plate. The connecting plate drives the horizontal plate to move backward. When the user picks up the concave shell vertically, the horizontal plate is used to hold the front of the mobile phone.

[0013] According to the above technical solution, rubber pads are respectively provided on the top of the sides of the L-shaped plates that are close to each other, and the horizontal plate is located in front of the U-shaped plate.

[0014] According to the above technical solution, the anti-loosening device includes: a U-shaped rod fixed to the bottom front of the connecting plate; a ring block fixed to the outer wall of the U-shaped rod, with a magnetic block fixed to the front of the ring block; and an L-shaped metal plate fixed to the top surface of the front cover, with the back of the L-shaped metal plate on the movement trajectory of the front of the magnetic block. The ring block drives the magnetic block to move backward, causing the magnetic block to leave the L-shaped metal plate. After the micro-drone body is recovered, the magnetic block resets. The magnetic block is used to attract the L-shaped metal plate.

[0015] According to the above technical solution, two square hole blocks are fixed to the outer wall of the U-shaped rod. An inclined plate is fixed to the top surface of each square hole block. A circular plate is fixed to the back of each inclined plate. The back of the circular plate is fixedly connected to the top of the front of the connecting plate. The square hole blocks drive the inclined plates to move backward, and the inclined plates drive the circular plates to move backward. The inclined plates support the movement of the U-shaped rod.

[0016] This invention provides a wearable micro-drone system based on the Internet of Things (IoT). It has the following beneficial effects: (1) The present invention uses a concave shell, a battery, front and rear modules one, left and right modules two, a U-shaped frame, a micro servo motor, a screw, a triangular ring, a U-shaped strip and a sliding cover to cooperate with the micro drone body. The rotating shaft of the micro servo motor drives the screw to rotate forward. The screw rotates forward in the U-shaped frame. Under the restriction of the sliding groove of the concave shell, the screw drives the triangular ring to move backward. The triangular ring drives the U-shaped strip to move backward. The U-shaped strip drives the sliding cover to move backward. The sliding cover moves backward away from the front cover. The sliding cover moves away from the top of the micro drone body. The micro drone body flies upward. The front and rear modules one and the left and right modules two send instructions to the mobile app software. The instructions are transmitted to the data processing center (local or cloud) through the communication module. A three-dimensional image is formed in the mobile app software. After the instructions are optimized by the mobile app software, the control instructions are generated and sent to the micro drone body. The micro drone body performs tasks (such as flying and shooting) and sends the data back. This enables the micro drone body to take off and take off on the concave shell, preventing the user from having to manually pick up the micro drone body to take off, which would cause inconvenience for the wearable micro drone to take off. (2) The present invention uses a clamping device to make the U-shaped plate, heat-conducting plate, round tube, sliding column and spring cooperate with the L-shaped plate. The U-shaped plate drives the round tube to move backward, the round tube drives the sliding column to move backward, the sliding column drives the spring to move backward, and the sliding column drives the L-shaped plate to move backward. The mobile phone is placed in the middle of the L-shaped plate. Under the action of the squeezing force, the sliding column moves to both sides in the round tube, the spring is pulled up, and the rubber pad of the L-shaped plate tightly clamps the mobile phone, preventing the inconvenience of placing the mobile phone from causing inconvenience in controlling the wearable micro drone. (3) The present invention, through the setting of the clamping device, makes the short column and the connecting plate cooperate with the horizontal plate. The connecting plate drives the horizontal plate to move backward. When the user picks up the concave shell vertically, the horizontal plate supports the bottom of the mobile phone, preventing the mobile phone from sliding down in the L-shaped plate and causing poor clamping effect of the L-shaped plate. (4) By setting the anti-loosening device, the U-shaped rod, the ring block and the magnetic block cooperate with the L-shaped metal plate. The ring block drives the magnetic block to move backward. The magnetic block leaves the L-shaped metal plate. After the micro UAV body is recovered, the magnetic block is reset. The magnetic block is magnetically attracted to the L-shaped metal plate to prevent the sliding cover from loosening and causing the micro UAV body in the sliding cover to be exposed. (5) By setting the anti-loosening device, the square hole block and the inclined plate cooperate with the round plate. The square hole block drives the inclined plate to move backward, and the inclined plate drives the round plate to move backward. The inclined plate supports the movement of the U-shaped rod, preventing the U-shaped rod from shaking and causing poor magnetic block adsorption effect. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Please see Figures 1-10 One embodiment of the present invention is: a wearable micro drone system based on the Internet of Things, comprising: a concave shell 1, with grooves on both the left and right sides of the inner wall of the concave shell 1, two batteries 2 fixedly installed at the bottom of the inner side of the concave shell 1, a front cover 101 fixedly installed on the top of the front side of the concave shell 1, and a hook 102 fixedly installed on both sides of the front side of the concave shell 1. The hook 102 is used to connect a hanging rope so that the user can conveniently carry the drone device. Front and rear module 1 3 is located on the left side of the inner wall of the concave shell 1. Left and right module 2 4 is located on the right side of the inner wall of the concave shell 1. U-shaped frame 5 is located between the two batteries 2 and is fixed to the bottom of the concave shell 1. A micro servo motor 6 is fixedly installed on the front of the U-shaped frame 5. A screw 7 is rotatably installed through the inner wall of the U-shaped frame 5. The outer wall of the screw 7 has a non-self-locking threaded groove. Triangular ring 8 is slidably installed on the outer wall of the screw 7. The inner wall of the triangular ring 8 meshes with the outer wall of the threaded groove of the screw 7. A U-shaped strip 9 is fixed on the top surface of the triangular ring 8. Sliding cover 10 is slidably connected to the inner wall of the sliding groove of the concave shell 1. The outer wall of the sliding cover 10 is connected to the U-shaped strip. The inner wall of the 9 is fixedly connected, and a sliding shaft is provided on both the left and right sides of the sliding cover 10. The sliding shaft of the sliding cover 10 is slidably connected to the inner wall of the sliding groove of the concave shell 1. The ends of the sliding shafts of the sliding cover 10 that are far apart from each other are fixedly connected to the inner wall of the U-shaped strip 9. The inner wall of the U-shaped strip 9 is slidably in contact with the top of the concave shell 1. The micro drone body 11 is placed in the middle of the top surface of the concave shell 1. The front and rear modules 1 3 are used to control the micro drone body 11 to fly forward and backward. The left and right modules 2 4 are used to control the micro drone body 11 to turn left and right. A vision module is provided at the rear of the micro drone body 11. A USB charging port is provided on the front of the micro drone body 11. The sliding cover 10 is used to protect the micro drone body 11. When using this device, the user unhooks the lanyard from the hook 102, picks up the concave shell 1, opens the mobile app, and connects to the main body 11 of the micro drone via the internet. Simultaneously, the user connects to the front and rear modules 3 and the left and right modules 4 via the internet. The user starts the micro servo motor 6 using the mobile app. The battery 2 supplies power to the micro servo motor 6, causing its shaft to rotate clockwise. This rotation drives the screw 7 to rotate clockwise within the U-shaped frame 5. Under the constraint of the groove in the concave shell 1, the screw 7 moves the triangular ring 8 backward, which in turn moves the U-shaped strip 9 backward. The U-shaped strip 9 then moves the sliding cover 10 backward. The sliding shaft of the sliding cover 10 slides backward within the groove in the concave shell 1, causing the sliding cover 10 to move backward away from the front cover 101 and above the main body 11 of the micro drone. The user then uses the mobile app... The micro-drone body 11 is activated and flies upward, allowing it to take off and ascend on the concave shell 1. This eliminates the need for the user to hold the micro-drone body 11, thus avoiding the inconvenience of manually picking up the micro-drone body 11 for takeoff, a problem common to wearable micro-drones. The user manually operates the front and rear modules 3 and the left and right modules 4 to control the micro-drone body 11. The front and rear modules 3 and the left and right modules 4 send commands to the mobile app. The commands are transmitted to the data processing center (local or cloud) via the communication module, where a 3D image is generated. After the commands are optimized by the mobile app, control commands are generated and sent to the micro-drone body 11. The micro-drone body 11 performs tasks (such as flying or taking pictures) and transmits the data back.

[0021] A clamping device 12 is provided on the top surface of the sliding cover 10. The clamping device 12 is used to clamp the mobile phone. An anti-loosening device 13 is provided on the front side of the clamping device 12. The anti-loosening device 13 is used to fasten the sliding cover 10 and the front cover 101.

[0022] Working principle: Unhook the lanyard from the hook 102, pick up the concave shell 1, connect the micro drone body 11 via mobile internet, connect the front and rear modules 3 and left and right modules 4 via mobile internet, the battery 2 supplies power to the micro servo motor 6, the shaft of the micro servo motor 6 drives the screw 7 to rotate forward, the screw 7 rotates forward in the U-shaped frame 5, under the constraint of the sliding groove of the concave shell 1, the screw 7 drives the triangular ring 8 to move backward, the triangular ring 8 drives the U-shaped strip 9 to move backward, the U-shaped strip 9 drives the sliding cover 10 to move backward, the sliding shaft of the sliding cover 10 slides backward in the sliding groove of the concave shell 1, the sliding cover 10 moves backward away from the front cover 101, the sliding cover 10 moves away from the front cover 101. Above the main body 11 of the micro drone, the main body 11 flies upward, enabling it to take off and ascend on the concave shell 1. The main body 11 of the micro drone is controlled manually by the front and rear modules 3 and the left and right modules 4. The front and rear modules 3 and the left and right modules 4 send commands to the mobile app software. The commands are transmitted to the data processing center (local or cloud) via the communication module. A three-dimensional image is formed in the mobile app software. After the commands are optimized by the mobile app software, control commands are generated and sent to the main body 11 of the micro drone. The main body 11 of the micro drone performs tasks (such as flying and taking pictures) and transmits the data back.

[0023] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, the clamping device 12 includes: a U-shaped plate 121, which is fixed in the middle of the top surface of the sliding cover 10; a heat-conducting plate 122, which is fixed in the middle of the top surface of the U-shaped plate 121; a round tube 123, which is fixed to the top of the inside of the U-shaped plate 121; a sliding column 124, which is slidably installed on the inner wall of the round tube 123 in pairs; a spring 125 is provided at the end of the sliding column 124 that is close to each other; and an L-shaped plate 126, which is fixed at the end of the sliding column 124 that is far from each other; a rubber pad is provided on the top of the side of the L-shaped plate 126 that is close to each other; and the L-shaped plate 126 clamps the mobile phone by the elastic force of the spring 125. As the U-shaped strip 9 moves the sliding cover 10 backward, the sliding cover 10 moves the U-shaped plate 121 backward, the U-shaped plate 121 moves the heat-conducting plate 122 backward, and simultaneously, the U-shaped plate 121 moves the round tube 123 backward, the round tube 123 moves the sliding column 124 backward, the sliding column 124 moves the spring 125 backward, and the sliding column 124 moves the L-shaped plate 126 backward. The user places the mobile phone in the middle of the L-shaped plate 126, and the rubber pad of the L-shaped plate 126 presses against the mobile phone. Under the action of the squeezing force, the sliding column 124 moves to both sides in the round tube 123, the spring 125 is pulled up, and the rubber pad of the L-shaped plate 126 tightly clamps the mobile phone. The heat-conducting plate 122 dissipates heat from the back of the mobile phone, thus avoiding the problem of inconvenient control of the wearable micro drone caused by the inconvenience of placing the mobile phone during use.

[0024] Two short posts 127 are fixed to the front of the U-shaped plate 121. A connecting plate 128 is fixed to the front of each of the short posts 127. A horizontal plate 129 is fixed to the top of the back of the connecting plate 128. The horizontal plate 129 is located in front of the U-shaped plate 121 and is used to hold the front of the mobile phone. As the U-shaped plate 121 moves the heat-conducting plate 122 backward, the U-shaped plate 121 also moves the short column 127 backward, the short column 127 moves the connecting plate 128 backward, and the connecting plate 128 moves the horizontal plate 129 backward. When the user picks up the concave shell 1 vertically, the horizontal plate 129 supports the bottom of the phone, thus avoiding the problem that the phone slides down in the L-shaped plate 126 during use of the wearable micro drone, causing the L-shaped plate 126 to have a poor clamping effect.

[0025] The anti-loosening device 13 includes: a U-shaped rod 131, which is fixed to the bottom front of the connecting plate 128; a ring block 132, which is fixed to the outer wall of the U-shaped rod 131; a magnetic block 133 is fixed to the front of the ring block 132; and an L-shaped metal plate 134, which is fixed to the top surface of the front cover 101. The back of the L-shaped metal plate 134 is on the movement trajectory of the front of the magnetic block 133, and the magnetic block 133 is used to attract the L-shaped metal plate 134. As the short column 127 moves the connecting plate 128 backward, the connecting plate 128 moves the U-shaped rod 131 backward, the U-shaped rod 131 moves the ring block 132 backward, the ring block 132 moves the magnetic block 133 backward, and the magnetic block 133 leaves the L-shaped metal plate 134. When the micro-drone body 11 is retrieved, the magnetic block 133 returns to its original position and is magnetically attached to the L-shaped metal plate 134, preventing the sliding cover 10 from becoming loose. This avoids the micro-drone body 11 inside the sliding cover 10 from being exposed during use due to the sliding cover 10 becoming loose.

[0026] Two square hole blocks 135 are fixed to the outer wall of the U-shaped rod 131. A diagonal strip 136 is fixed to the top surface of each square hole block 135. A circular plate 137 is fixed to the back of each diagonal strip 136. The back of the circular plate 137 is fixedly connected to the top of the front of the connecting plate 128. While the U-shaped rod 131 drives the ring block 132 to move backward, the U-shaped rod 131 drives the square hole block 135 to move backward, the square hole block 135 drives the inclined plate 136 to move backward, the inclined plate 136 drives the circular plate 137 to move backward, and the inclined plate 136 supports the movement of the U-shaped rod 131, thereby avoiding the problem that the vibration of the U-shaped rod 131 during the use of the wearable micro drone causes poor adsorption effect of the magnetic block 133.

[0027] Working principle: The sliding cover 10 drives the U-shaped plate 121 to move backward, the U-shaped plate 121 drives the heat-conducting plate 122 to move backward, the U-shaped plate 121 drives the round tube 123 to move backward, the round tube 123 drives the sliding column 124 to move backward, the sliding column 124 drives the spring 125 to move backward, the sliding column 124 drives the L-shaped plate 126 to move backward, and the mobile phone is placed in the middle of the L-shaped plate 126, and the rubber pad of the L-shaped plate 126 presses against the mobile phone; The U-shaped plate 121 drives the short column 127 to move backward, the short column 127 drives the connecting plate 128 to move backward, the connecting plate 128 drives the horizontal plate 129 to move backward, and the horizontal plate 129 supports the bottom of the mobile phone. The connecting plate 128 drives the U-shaped rod 131 to move backward, the U-shaped rod 131 drives the ring block 132 to move backward, the ring block 132 drives the magnetic block 133 to move backward, the magnetic block 133 leaves the L-shaped metal plate 134, after the micro drone body 11 is recovered, the magnetic block 133 is reset, and the magnetic block 133 is magnetically attracted to the L-shaped metal plate 134. U-shaped rod 131 drives square hole block 135 to move backward, square hole block 135 drives inclined plate 136 to move backward, inclined plate 136 drives circular plate 137 to move backward, and inclined plate 136 supports the movement of U-shaped rod 131.
