Description

Technical Field

[0001] The present invention belongs to the technical field of suspended flight control devices, and particularly relates to a suspended flight control aluminum film balloon. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self - contained program control device. In the prior art, currently common drones have the characteristics of strong maneuverability and simple operation. However, due to flight principle problems, when traditional drones face low - speed flight, the air flow velocity of the wings or rotors decreases, resulting in insufficient lift and insufficient flight stability. Limited by the limited battery capacity and the high - energy - consumption characteristics during flight, if long - time hovering ability such as more than 24 hours is required, traditional drones often need to increase the battery or adopt fuel power, which leads to a large volume and high cost.

[0003] Furthermore, there are still certain safety problems when a drone crashes accidentally during operation. At the same time, most of the suspension and release devices of existing drones are designed for dropping heavier objects, and the release devices for lightweight and numerous objects in the entertainment field, such as dropping balloons, are urgently needed to be developed. Summary of the Invention

[0004] The object of the present invention is to provide a suspended flight control aluminum film balloon for entertainment activity scenarios such as weddings, which require low - speed flight and focus on safety.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A suspended flight control aluminum film balloon, including an aluminum film balloon, a balloon power device and a pod suspension device are respectively arranged on the aluminum film balloon, and the balloon power device and the pod suspension device are both connected to a balloon power control board and controlled by the balloon power control board. The combination of the aluminum film balloon and the balloon power device can stay in the air for a long time at high altitude. At the same time, through the pod suspension device, specific types of items can be hung and remotely dropped, and the operating noise is more than 30 dB lower than that of traditional drones, which is suitable for operation in densely populated areas or ecologically sensitive areas.

[0006] In the above - mentioned suspended flight control aluminum film balloon, the balloon power device is detachably fixed at the lower end of the aluminum film balloon, and the pod suspension device is arranged at the lower end of the balloon power device.

[0007] In the above-mentioned levitation flight control aluminum film balloon, it is characterized in that the balloon power device includes a framework arranged at the lower end of the aluminum film balloon through a detachable installation structure. A battery installation bin is provided on the framework, and a lithium battery is installed in the battery installation bin. The lithium battery is connected to a power component arranged on the circumferential outer side of the framework. The balloon power control board is installed at the upper end of the framework and is connected to the power component. Using a lithium battery as the power source to provide power for the power component, it has a high energy density and conversion efficiency, and can provide stable power for the device.

[0008] In the above-mentioned levitation flight control aluminum film balloon, the power component includes four motor installation slots respectively arranged at the four corners of the framework in the circumferential direction. Two of the four motor installation slots corresponding to each other are arranged horizontally, and the remaining two corresponding motor installation slots are arranged vertically. Hollow cup motors connected to the balloon power control board are respectively installed in the motor installation slots, and blades are provided on the output shafts of the hollow cup motors. The vertically installed hollow cup motors provide upward lift to achieve hovering at a fixed position. The horizontally installed hollow cup motors can rotate at different frequencies according to the motion control program, so as to provide forward thrust and complete steering and air disturbance correction at the same time.

[0009] In the above-mentioned levitation flight control aluminum film balloon, the detachable installation structure includes two clamping blocks arranged on both sides of the middle part of the lower surface of the aluminum film balloon by bonding. Slots are respectively provided on the clamping blocks. Two vertically arranged buckles corresponding to the clamping blocks one by one are provided on the framework, and the buckles are clamped with the slots. It is convenient for the installation, disassembly and maintenance of the balloon power device, and reduces the maintenance cost and difficulty.

[0010] In the above-mentioned levitation flight control aluminum film balloon, the pod suspension device includes a pod fixing bracket arranged at the lower end of the framework. A micro-motion slide rail mechanism and a release component linked to the micro-motion slide rail mechanism are provided on the pod fixing bracket.

[0011] In the above-mentioned levitation flight control aluminum film balloon, the micro-motion slide rail mechanism is a micro screw table assembly. The micro screw table assembly includes a slide table bracket arranged on the pod fixing bracket. A guide rod is provided on the slide table bracket, and a slide table body axially slidably connected to the guide rod is provided. The slide table body is threadedly connected to a screw body. A micro stepping motor connected to the screw body is provided at one end of the slide table bracket, and the micro stepping motor is connected to the balloon power control board. The micro screw table assembly can achieve precise position control. By controlling the micro stepping motor through the balloon power control board, the position of the slide table body can be accurately adjusted.

[0012] In the above-mentioned suspended flight control aluminum film balloon, the release assembly includes several vertical plates that are sequentially distributed along the axis of the pod fixing bracket and are located on one side of the micro-moving slide rail mechanism on the pod fixing bracket. The vertical plates are respectively arranged vertically, and circular slots are respectively formed in each vertical plate. The centers of the circular slots of the vertical plates are located on the same straight line, and a suspension space is formed between adjacent vertical plates. One side of the slide body is provided with a release guide rod through an installation card slot, and the release guide rod sequentially slides through the circular slots of each vertical plate, and several rings respectively located in the suspension space and connected to the suspended object are sleeved on the release guide rod. The precise release of the suspended object can be realized. Through the cooperation of the release guide rod and the vertical plate, the suspended object can be released in sequence according to the installation requirements to meet different task requirements.

[0013] In the above-mentioned suspended flight control aluminum film balloon, the aluminum film balloon is filled with low-density gas inside. Multiple pod suspension devices can be installed at the lower end of the framework, and the pod suspension devices are detachably connected to the framework. The mass of the aluminum film balloon is set by weighing, so that the buoyancy is slightly less than the overall weight of the equipment. Thus, the overall equipment can achieve slow and safe landing by relying on its own weight when no suspended object is dropped or a small amount of suspended objects are dropped. At the same time, the equipment has a safety landing design. When the weight of the equipment is severely reduced due to factors such as dropping suspended objects, it can rely on the horizontally arranged hollow plate motor and blades to achieve passive landing.

[0014] In the above-mentioned suspended flight control aluminum film balloon, the balloon power control board has any one or a combination of wireless communication chips, attitude angle sensors, and built-in acceleration sensors. By controlling the rotation speed and direction of the coreless motor through the attitude angle sensor and the built-in acceleration sensor, the flight trajectory can be corrected autonomously in real time during flight.

[0015] Compared with the existing technology, the advantages of the present invention are as follows:

[0016] 1. The device combines the balloon power device with the aluminum film balloon beneficially. On the basis of realizing highly maneuverable flight, the aluminum film balloon is skillfully used to provide part of the lift during flight, reducing the flight energy consumption, and enabling long-time hovering flight and hovering at low energy consumption.

[0017] 2. Through the aluminum film balloon structure, even if there is an accidental power failure during flight, the aluminum film balloon can provide buffering to reduce the risk of hard landing, achieve the overall safe landing, be safe and reliable, and reduce losses.

[0018] 3. The device can realize the batch dropping of suspended objects through the release assembly and the micro-moving slide rail mechanism. At the same time, a card slot structure is reserved on the lower surface of the framework, and the fixed suspension of various types of loads can be realized.

[0019] 4. The device has a simple structure and is easy to install. The aluminized film balloon and the framework, as well as the framework and the gondola fixing bracket, are all connected in a detachable manner, thus realizing the installation between the aluminized film balloon and the framework and the rapid replacement of different suspension devices.

Detailed Description of the Invention

[0024] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0025] As Figures 1-3 shown, a floating flight control aluminized film balloon includes an aluminized film balloon 1, on which a balloon power device 2 and a gondola suspension device 3 are respectively provided. The balloon power device 2 and the gondola suspension device 3 are both connected to the balloon power control board 4 and controlled by the balloon power control board 4. The combination of the aluminized film balloon 1 and the balloon power device 2 can stay at high altitude for a long time. At the same time, specific types of items can be mounted and remotely dropped through the gondola suspension device 3, and the operating noise is more than 30 dB lower than that of traditional drones, making it suitable for operations in densely populated areas or ecologically sensitive regions.

[0026] Combined with Figure 1 and Figure 2 shown, the balloon power device 2 is detachably fixed at the lower end of the aluminized film balloon 1, and the gondola suspension device 3 is arranged at the lower end of the balloon power device 2.

[0027] Among them, the balloon power device 2 includes a framework 21 arranged at the lower end of the aluminum film balloon 1 through a detachable installation structure 5. A battery installation bin 22 is provided on the framework 21, and a lithium battery 23 is installed in the battery installation bin 22. The lithium battery 23 is connected to a power assembly 6 arranged on the circumferential outer side of the framework 21. The balloon power control board 4 is installed at the upper end of the framework 21 and is connected to the power assembly 6. Using the lithium battery 23 as the power source to provide power for the power assembly 6, it has a relatively high energy density and conversion efficiency, and can provide stable power for the device.

[0028] Specifically, the power assembly 6 includes four motor installation slots 61 respectively arranged at the four circumferential corners of the framework 21. Two of the four motor installation slots 61 corresponding to each other are arranged horizontally, and the remaining two corresponding motor installation slots 61 are arranged vertically. Hollow cup motors 62 connected to the balloon power control board 4 are respectively installed in the motor installation slots 61, and blades 63 are provided on the output shafts of the hollow cup motors 62. The vertically installed hollow cup motors 62 provide upward lift to achieve hovering at a fixed position. The horizontally installed hollow cup motors 62 can rotate at different frequencies according to the motion control program, so as to provide forward thrust and complete steering and air disturbance correction at the same time.

[0029] Furthermore, the detachable installation structure 5 includes two clamping blocks 51 arranged on both sides of the middle part of the lower surface of the aluminum film balloon 1 by bonding. Claw slots 52 are respectively provided on the clamping blocks 51. Two vertically arranged buckles 53 corresponding to the clamping blocks 51 one by one are provided on the framework 21, and the buckles 53 are clamped with the claw slots 52. It is convenient for the installation, disassembly and maintenance of the balloon power device 2, and reduces the maintenance cost and difficulty.

[0030] As Figure 3 shown, the pod suspension device 3 includes a pod fixing bracket 31 arranged at the lower end of the framework 21. A micro-motion slide rail mechanism 7 and a release component 8 linked with the micro-motion slide rail mechanism 7 are provided on the pod fixing bracket 31.

[0031] Among them, the micro-motion slide rail mechanism 7 is a micro screw slide table assembly. The micro screw slide table assembly includes a slide table bracket 71 arranged on the pod fixing bracket 31. A guide rod 72 and a slide table body 73 axially slidably connected to the guide rod 72 are provided on the slide table bracket 71. The slide table body 73 is threadedly connected to a screw body 74. A micro stepping motor 75 connected to the screw body 74 is provided at one end of the slide table bracket 71, and the micro stepping motor 75 is connected to the balloon power control board 4. The micro screw slide table assembly can achieve precise position control. By controlling the micro stepping motor 75 through the balloon power control board 4, the position of the slide table body 73 can be accurately adjusted.

[0032] Specifically, the release component 8 includes a number of vertical plates 81 that are axially distributed in sequence along the gondola fixing bracket 31 and are located on one side of the micro-moving slide rail mechanism 7. The vertical plates 81 are respectively arranged vertically, and circular slot holes 82 are respectively formed in each vertical plate 81. The centers of the circular slot holes 82 of the vertical plates 81 are located on the same straight line, and a suspension space 83 is formed between adjacent two vertical plates 81. One side of the slide body 73 is provided with a release guide rod 84 through an installation card slot 52, and the release guide rod 84 sequentially slides through the circular slot holes 82 of each vertical plate 81, and a number of rings that are respectively located in the suspension space 83 and are connected to the suspended object are sleeved on the release guide rod 84. Precise release of the suspended object can be achieved. Through the cooperation of the release guide rod 84 and the vertical plates 81, the suspended object can be released in sequence according to the installation requirements to meet different mission requirements.

[0033] As Figure 1 shown, the aluminum film balloon 1 is filled with low-density gas inside. Multiple gondola suspension devices 3 can be installed at the lower end of the framework 21, and the gondola suspension devices 3 are detachably connected to the framework 21. The mass of the aluminum film balloon 1 is set by weighing, so that the buoyancy is slightly less than the overall weight of the device. Thus, the device as a whole can achieve slow and safe landing by its own weight when no suspended object is dropped or a small amount of suspended objects are dropped. At the same time, the device is reserved with a safety landing design. When the weight of the device is severely reduced due to factors such as dropping suspended objects, passive landing can be achieved by relying on the horizontally arranged hollow plate motor 62 and the blades 63.

[0034] Among them, the balloon power control board 4 has any one or a combination of a wireless communication chip, an attitude angle sensor, and a built-in acceleration sensor. By controlling the rotation speed and direction of the coreless motor 62 through the attitude angle sensor and the built-in acceleration sensor, the flight trajectory can be corrected autonomously in real time during flight.

[0035] The principle of this embodiment lies in:

[0036] The aluminum film balloon 1 is filled with low-density gas, and the device is subject to an upward buoyant force. Since the density of the low-density gas is less than that of the surrounding air, the device can generate buoyancy in the air and thus achieve suspension. The lithium battery 23 powers the power assembly 6. Under the control of the balloon power control board 4, the coreless motor 62 starts and drives the blade 63 to rotate. By controlling the rotation speed and direction of the coreless motors 62 in different directions, thrusts in different directions and of different magnitudes are generated, thereby realizing actions such as the forward movement, backward movement, turning, and lifting of the device. The attitude angle sensor and the built-in acceleration sensor can real-time monitor the attitude and motion state information of the device and feedback this data to the balloon power control board 4. The balloon power control board 4, based on the received information, precisely controls the flight attitude of the device by adjusting the power output of each coreless motor 62 to ensure that the device maintains a stable flight attitude. When a suspension object needs to be installed, the suspension object is connected to the ring, and the ring is placed in the suspension space 83. The micro stepping motor 75 drives the lead screw body 74, and the slide table body 73 moves through the lead screw body 74. One end of the release guide rod 84 is connected to the slide table body 73, and the end of the release guide rod 84 away from the slide table body 73 sequentially passes through the circular slot hole 82 of the vertical plate 81 and is connected to the ring, thereby realizing the installation of the suspension object; when the suspension object needs to be released, the micro stepping motor 75 drives the lead screw body 74, and the slide table body 73 follows and moves. Then the slide table body 73 drives the release guide rod 84 to move away from the vertical plate 81 in sequence, and the ring is separated from the release guide rod 84, thereby realizing the release of the suspension object.
