Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), and in particular to a UAV parachute deployment device. Background Technology
[0002] In recent years, drone technology has developed rapidly and has been widely used in various fields. In order to achieve specific mission requirements, such as material delivery and equipment deployment, drones need to be equipped with reliable parachute delivery devices.
[0003] Existing parachute drop devices for drones are generally installed inside the drone's fuselage. Since these devices are typically only used in complex environments or when drones are prone to accidents, they are not needed in most normal situations. However, existing parachute drop devices are fixed inside the fuselage and are not easy to remove, which makes it impossible to use them flexibly according to the actual environmental conditions.
[0004] To address the issue that the parachute deployment device is fixed inside the drone and cannot be used flexibly according to the actual environmental conditions, a drone parachute deployment device can be designed. By using an externally mounted and detachable parachute deployment device, the drone can flexibly use the parachute deployment device according to the actual environmental conditions. Utility Model Content
[0005] To overcome the problem that the parachute delivery device is fixed inside the drone and cannot be used flexibly according to the actual environmental conditions.
[0006] The technical solution of this utility model is as follows: a drone parachute deployment device, including a top plate, a bottom plate, a first support wall, a second support wall, a partition, a launch mechanism, and a disassembly mechanism. The top plate is installed on the top of the drone, and the support launch mechanism is installed on the top plate for support. A horizontally placed bottom plate is provided above the top plate. The second support wall is fixedly connected to both the front and rear sides of the bottom plate. The first support wall is installed on both the left and right sides of the bottom plate. A partition is provided on the opposite side of the first support wall, dividing the bottom plate into two spaces. The left side of the partition is the launch compartment, and the right side of the partition is the control compartment. The launch mechanism is installed above the bottom plate, and the disassembly mechanism is located at the four corners of the bottom plate.
[0007] Preferably, the base plate is used to support the ejection mechanism and the disassembly mechanism. The ejection mechanism ejects the parachute in the event of an accident involving the drone. The partition divides the ejection mechanism into an ejection compartment and a control compartment to prevent the electronic components in the control compartment from being damaged due to contact with foreign objects. The quick-release structure in the disassembly mechanism allows the parachute device to be quickly and easily removed and replaced.
[0008] Preferably, the ejection mechanism includes a cover, a reinforcing plate, a controller, a transmission line, and a sensor. The partition is fixedly connected to the first support wall via the cover to seal the control compartment. The sensor is installed on the right side of the partition and fixed to the partition. The controller is located behind the sensor and is fixedly connected to the controller via the transmission line. The reinforcing plate is installed on the right side of the sensor. The cover seals the control compartment to prevent the electronic components inside the control compartment from malfunctioning due to contact with external dirt. The reinforcing plate enhances the signal of the electronic components inside the control compartment. When the sensor detects that the drone is out of control, it sends the signal to the controller via the transmission line, and then the controller activates the parachute device.
[0009] Preferably, the ejection mechanism also includes a sliding cover, a support frame, a support block, a movable rod, a first hook, a second hook, and a rotating column. An openable sliding cover is located above the ejection chamber. A cuboid support frame is located on the left side of the partition. Support blocks are located on both the front and rear sides of the support frame. The movable rod is installed on the opposite side of the support blocks. The first hook is installed on the movable rod. A second hook, which cooperates with the first hook, is located on the right side of the sliding cover. A rotating column is located below the left side of the sliding cover. A torsion spring is installed on the rotating column, and the rotating column can open the sliding cover through the torsion spring. When the parachute device is not activated, the first hook and the second hook are engaged together. When the parachute device is activated, the controller moves the second hook to the right. After the first hook is released from the restraint of the second hook, the sliding cover is ejected by the torsion spring, and the parachute inside the ejection chamber opens with the wind.
[0010] As a preferred embodiment, each of the two support walls has two horizontal mounting plates on opposite sides. On the opposite side of the mounting plates, there are several comb posts for organizing the parachute lines. The lines on the parachute pass through the comb posts on the mounting plates one by one, so that the lines will not get tangled together when the parachute is opened, thus preventing the parachute from becoming unusable.
[0011] Preferably, the disassembly mechanism includes a fixing column, a fixing sleeve, and a limiting plate. The fixing columns are installed at the four corners of the base plate and are fixedly connected to the base plate. The fixing sleeve is located in the middle of the fixing column. The fixing sleeve is a cylindrical structure with openings at the top and bottom. The top plate of the drone has a fixing hole aligned with the opening at the bottom of the fixing sleeve. The upper part of the inner wall of the fixing sleeve has a limiting plate to prevent the object from falling off. The fixing column fixes the parachute device to the drone. The fixing sleeve is used to assemble the fixing mechanism. The limiting plate prevents the fixing mechanism from falling off.
[0012] Preferably, the disassembly mechanism includes a fixing rod, a strong spring, and a cylindrical cam. The fixing sleeve has a fixing rod that extends into a fixing hole on the top plate. The cylindrical cam is installed above the fixing rod. The fixing rod has a strong spring. The cylindrical cam presses down on the strong spring to force the fixing rod into the fixing hole on the top plate, thus fixing the parachute device.
[0013] Preferably, the disassembly mechanism also includes a connecting rod, a slider, a limiting platform, and a rotary button. The connecting rod is located above the cylindrical cam, the slider is installed below the connecting rod and can cooperate with the cylindrical cam, the limiting platform is installed above the slider, and a rotary button is located above the connecting rod to rotate the connecting rod. Rotating the rotary button causes the slider to slide on the cylindrical cam, allowing the cylindrical cam to move up and down.
[0014] The beneficial effects of this utility model are:
[0015] 1. By adding a disassembly mechanism, the parachute device, which was originally located inside the drone, was moved to the top of the drone, reducing the space occupied inside the drone and the impact on the installation of other functional equipment (such as camera detection equipment).
[0016] 2. The loading and unloading mechanism allows for easy removal and replacement of the drone's parachute deployment device, enabling the drone to flexibly use the parachute deployment device according to the actual environmental conditions. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figure 1 This utility model provides an embodiment: a drone parachute deployment device, including a top plate 1, a bottom plate 2, a first support wall 3, a second support wall 29, a partition 4, a pop-out mechanism, and a disassembly mechanism. The top plate 1 is installed on the top of the drone, and the support pop-out mechanism is installed on the top plate 1 for support. The bottom plate 2 is horizontally placed above the top plate 1. The second support wall 29 is fixedly connected to both the front and rear sides of the bottom plate 2. The first support wall 3 is installed on both the left and right sides of the bottom plate 2. A partition is provided on the opposite side of the first support wall 3. Plate 4 and partition 4 divide the base plate 2 into two spaces. The left side of partition 4 is the ejection compartment, and the right side of partition 4 is the control compartment. The ejection mechanism is installed on the top of the base plate 2, and the disassembly mechanism is located at the four corners of the base plate 2. The base plate 2 is used to support the ejection mechanism and the disassembly mechanism. The ejection mechanism will eject the parachute in the event of an accident involving the drone. The partition 4 divides the ejection mechanism into the ejection compartment and the control compartment to prevent the electronic components in the control compartment from being damaged due to contact with foreign objects. The quick-release structure in the disassembly mechanism allows the parachute device to be quickly and easily removed and replaced.
[0025] Please see Figures 1-2In this embodiment, the ejection mechanism includes a cover 6, a reinforcing plate 5, a control unit 8, a transmission line 9, and a sensor 10. The partition 4 is fixedly connected to the first support wall 3 via the cover 6, sealing the control compartment. The sensor 10 is installed on the right side of the partition 4 and fixed to it. The control unit 8 is located behind the sensor 10 and is fixedly connected to it via the transmission line 9. The reinforcing plate 5 is installed on the right side of the sensor 10. The cover 6 seals the control compartment to prevent the electronic components inside from malfunctioning due to contact with external contaminants. The reinforcing plate 5 enhances the signal of the electronic components inside the control compartment. When the sensor 10 senses the drone's loss of control, it sends a signal to the control unit 8 via the transmission line 9, and the control unit 8 then activates the parachute device. The ejection mechanism also includes a sliding cover 7, a support frame 11, a support block 12, and a movable rod 13. The system includes a first hook 14, a second hook 15, and a rotating column 16. Above the ejection chamber is an openable sliding cover 7. On the left side of the partition 4 is a cuboid support frame 11, with support blocks 12 on both the front and rear sides of the support frame 11. A movable rod 13 is installed on the opposite side of the support block 12, and the first hook 14 is installed on the movable rod 13. On the right side of the sliding cover 7 is a second hook 15 that cooperates with the first hook 14. A rotating column 16 is located on the lower left side of the sliding cover 7. The rotating column 16 is equipped with a torsion spring, and the rotating column 16 can open the sliding cover 7 through the torsion spring. When the parachute device is not activated, the first hook 14 and the second hook 15 are engaged together. When the parachute device is activated, the controller 8 moves the second hook 15 to the right. After the first hook 14 is freed from the restraint of the second hook 15, the sliding cover 7 is ejected by the torsion spring, and the parachute in the ejection chamber opens with the wind.
[0026] Please see Figures 2-3 In this embodiment, two horizontal mounting plates 17 are provided on opposite sides of the second support wall 29. Several comb posts 18 for organizing parachute lines are distributed on opposite sides of the mounting plates 17. The lines on the parachute pass through the comb posts 18 on the mounting plates 17 one by one, so that the lines will not get tangled together when the parachute opens, making the parachute unusable. The disassembly mechanism includes a fixing post 19, a fixing sleeve 20, and a limiting plate 21. The fixing post 19 is installed at the four corners of the base plate 2 and is fixedly connected to the base plate 2. The fixing sleeve 20 is provided in the middle of the fixing post 19. The fixing sleeve 20 is a cylindrical structure with holes at the top and bottom. The top plate 1 is provided with fixing holes aligned with the lower opening of the fixing sleeve 20. The upper part of the inner wall of the fixing sleeve 20 is provided with a limiting plate 21 to prevent objects from falling off. The fixing post 19 fixes the parachute device to the UAV. The fixing sleeve 20 is used to assemble the fixing mechanism. The limiting plate 21 prevents the fixing mechanism from falling off.
[0027] Please see Figure 4In this embodiment, the disassembly mechanism includes a fixed rod 22, a strong spring 23, and a cylindrical cam 24. The fixed sleeve 20 is provided with a fixed rod 22 extending into a fixed hole on the top plate 1. The cylindrical cam 24 is installed above the fixed rod 22. The fixed rod 22 is provided with a strong spring 23. The cylindrical cam 24 presses down on the strong spring 23 to make the fixed rod 22 squeeze into the fixed hole on the top plate 1, thereby fixing the parachute device. The disassembly mechanism also includes a connecting rod 25, a slider 26, a limiting platform 27, and a rotary button 28. The connecting rod 25 is provided above the cylindrical cam 24. The slider 26 is installed below the connecting rod 25 and can cooperate with the cylindrical cam 24. The limiting platform 27 is installed above the slider 26. The rotary button 28 is provided above the connecting rod 25 to make the connecting rod 25 rotate. Rotating the rotary button 28 makes the slider 26 slide on the cylindrical cam 24, allowing the cylindrical cam 24 to move up and down. During operation, first align the hole below the fixing sleeve 20 with the fixing hole on the top plate 1, then rotate the rotary button 28 to make the rotary button 28 drive the connecting rod 25 to rotate. The connecting rod 25 then drives the slider 26 to rotate along the trajectory above the cylindrical cam 24. When the slider 26 rotates to the highest point above the cylindrical cam 24, the cylindrical cam 24 moves downward. The fixing rod 22, which is fixedly connected to the cylindrical cam 24, also moves downward. The cylindrical cam 24 compresses the strong spring 23, causing the fixing rod 22 to be squeezed into the fixing hole on the top plate 1. When it is necessary to remove, rotate the rotary button 28 again to make the slider 26 reach the lowest point of the cylindrical cam 24. The cylindrical cam 24 loses the force applied to it by the slider 26 and is moved upward by the elastic force of the strong spring 23, pulling the fixing rod 22 out of the fixing hole.
[0028] Then, when the drone malfunctions, the sensor 10 senses the drone's loss of control and sends a signal to the controller 8 through the transmission line 9. The controller 8 then activates the parachute device. When the parachute device is not activated, hook 14 and hook 15 are engaged together. When the parachute device is activated, the controller 8 moves hook 15 to the right. After hook 14 is freed from the restraint of hook 15, the sliding cover 7 is ejected by the torsion spring, and the parachute in the ejection compartment is opened by the wind.
[0029] Through the above steps, the parachute device, originally located inside the drone, was moved to the top of the drone by adding a disassembly mechanism. This reduces the space occupied inside the drone and minimizes the impact on the setup of other functional devices. It also allows the parachute device to be easily removed and replaced, enabling the drone to use the parachute deployment device flexibly according to the actual environmental conditions. This solves the problem that the parachute deployment device, which is fixed inside the drone, cannot be used flexibly according to the actual environmental conditions.
[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
