Abstract
Description
Technical Field
[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a mobile hexacopter UAV. Background Technology
[0002] A drone, also known as an unmanned aircraft or a remotely piloted aircraft, is an unmanned aircraft controlled by radio remote control equipment and its own program control device.
[0003] The propellers of conventional drones are exposed without protection. When drones are used, especially in forested areas, the propellers are prone to colliding with leaves, easily causing damage. Furthermore, when parking the drone, beginners may mishandle it just before it touches the ground, causing it to plummet. The impact upon landing generates significant vibrations, which can damage internal components and shorten the overall lifespan of the drone. Therefore, we propose a mobile hexacopter drone. Utility Model Content
[0004] The purpose of this invention is to provide a mobile hexacopter unmanned aerial vehicle (UAV) to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a mobile hexacopter unmanned aerial vehicle, including a fuselage, characterized in that it further includes:
[0006] Two E-shaped frames are fixedly installed on both sides of the fuselage. Three propellers are rotatably mounted on the E-shaped frames. A protective frame is provided on the top of the E-shaped frames. Three round holes are opened in the protective frame. The propellers are located in the corresponding round holes. A protective strip is fixedly installed in the round holes and above the propellers. Two through slots are opened on the E-shaped frames. Limiting blocks fixed to the protective frame are inserted into the through slots.
[0007] Two sets of fixing components are located in two E-shaped frames respectively and are used to fix four limiting blocks;
[0008] Two brackets are fixedly installed on both sides of the machine body. A base plate is provided below the brackets. Two limiting grooves are opened at the bottom of the brackets. A damping rod is fixedly installed in the limiting groove. A sliding block fixed to the top of the base plate is fixedly installed at one end of the damping rod. A second spring is sleeved on the damping rod.
[0009] In this technical solution, during installation, the operator inserts the two limiting blocks at the bottom of the protective frame into the two through slots on the E-shaped frame. The fixing components then secure the two limiting blocks in their respective through slots. The protective frame is then fixed to the E-shaped frame, and the three blades on the E-shaped frame are positioned within the three circular holes on the protective frame. The protective strip inside the protective frame is positioned above the corresponding blade, thus protecting it. Once both protective frames are installed, the system is ready for use. The protective strip and frame effectively protect the blades, preventing damage from impacts in case of improper operation.
[0010] When the entire device rapidly descends to the ground, the two base plates will make contact with the ground first. The base plates will cause the sliding blocks to move upward, and the sliding blocks will cause the damping rods to contract. At this time, the second spring will also contract due to the compression of the sliding blocks. Subsequently, under the action of the rebound force of the second spring, the second spring will cause the sliding blocks to move downward, thereby causing the damping rods to extend. Under the action of the four damping rods and the four second springs, the force on the two base plates can be effectively buffered, thereby avoiding large vibrations to the entire device and preventing damage to the parts inside the machine.
[0011] In the above technical solution, the fixing component further includes:
[0012] Two sliding grooves are provided, both of which are formed within an E-shaped frame. A slider is slidably installed within each sliding groove. The ends of the two sliders that are far apart pass through the ends of the two sliders and extend into two limiting blocks. An L-shaped rod is fixedly installed on the opposite side of each of the two sliders. A groove is formed within the E-shaped frame between the two sliding grooves. The opposite ends of the two L-shaped rods pass through the opposite side of the two sliding grooves and extend into the groove. A first spring is fitted on the L-shaped rod within the sliding groove.
[0013] In this technical solution, the worker first presses the two L-shaped rods on the E-shaped frame with his hand, so that the two L-shaped rods are close to each other. At this time, the first spring will be compressed by the slider until the slider moves out of the through groove and completely enters the slide groove. Then, the worker inserts the two limiting blocks at the bottom of the protective frame into the two through grooves on the E-shaped frame respectively, and then releases his hand. Under the action of the rebound force of the two first springs, the two first springs will drive the two sliders away from each other until the ends of the two sliders that are far apart are inserted into the two limiting blocks respectively. At this time, the protective frame will be fixed on the E-shaped frame.
[0014] In the above technical solution, one end of the slider is inserted into the corresponding limiting block, the L-shaped rod is slidably connected to the corresponding slide groove and the corresponding E-shaped frame, and the two ends of the first spring are respectively tightly welded to the inner wall of the slide groove and the end of the slider near the groove.
[0015] In this technical solution, it is ensured that one end of the slider can be inserted into the limiting block, that the L-shaped rod can slide in the groove and the E-shaped frame, and that the structure of the first spring is stable.
[0016] In the above technical solution, the protective frame and the limiting block are integrally formed, and the sliding block and the base plate are integrally formed.
[0017] In this technical solution, the structural stability between the protective frame and the limiting block is ensured, and the structural stability between the sliding block and the base plate is guaranteed.
[0018] In the above technical solution, the two ends of the second spring are fixedly connected to the top of the sliding block and the inner wall of the limiting groove, respectively, and the sliding block is slidably connected to the limiting groove.
[0019] In this technical solution, the structure of the second spring is ensured to be stable, so that the sliding block can slide within the limiting groove.
[0020] In the above technical solution, the two E-shaped frames are arranged symmetrically.
[0021] In this technical solution, the two E-shaped frames are symmetrically arranged to ensure that the overall device can operate normally.
[0022] The beneficial effects of this utility model are:
[0023] 1. This mobile hexacopter UAV, through the cooperation of a protective frame, protective strips, limit blocks, through slots, round holes, E-shaped brackets and fixing components, ensures effective protection of the propeller blades, prevents the blades from touching leaves, and prevents damage to the blades during operation.
[0024] 2. This mobile hexacopter UAV, through the cooperation of its bracket, base plate, limiting groove, damping rod, second spring and sliding block, ensures that the overall device can effectively buffer the impact force received by the device during descent, thereby preventing damage to the internal parts of the fuselage.

[0039] Example 1:
[0040] Please see Figure 1 - Figure 7 As shown, this embodiment provides a mobile hexacopter unmanned aerial vehicle (UAV), including a fuselage 1, and further comprising:
[0041] Two E-shaped frames 2 are fixedly installed on both sides of the fuselage 1. Three propellers 7 are rotatably installed on the E-shaped frames 2. A protective frame 3 is provided on the top of the E-shaped frame 2. Three round holes are opened in the protective frame 3. The propellers 7 are located in the corresponding round holes. A protective strip 4 is fixedly installed in the round holes and above the propellers 7. Two through slots 6 are opened on the E-shaped frame 2. A limiting block 8 fixed to the protective frame 3 is inserted into the through slot 6.
[0042] Two sets of fixing components are located in two E-shaped frames 2 respectively, and are used to fix four limit blocks 8;
[0043] Two brackets 5 are fixedly installed on both sides of the body 1. A base plate 17 is provided below the brackets 5. Two limiting grooves 15 are opened at the bottom of the brackets 5. A damping rod 16 is fixedly installed in the limiting groove 15. A sliding block 18 fixed to the top of the base plate 17 is fixedly installed at one end of the damping rod 16. A second spring 14 is sleeved on the damping rod 16.
[0044] During installation, the workers insert the two limiting blocks 8 at the bottom of the protective frame 3 into the two through slots 6 on the E-shaped frame 2. The fixing components fix the two limiting blocks 8 in the corresponding through slots 6. At this time, the protective frame 3 will be fixed on the E-shaped frame 2, and the three blades 7 on the E-shaped frame 2 will be located in the three round holes on the protective frame 3. The protective strip 4 inside the protective frame 3 will be above the corresponding blade 7, thus protecting the blade 7. After both protective frames 3 are installed, they can be used. With the action of the protective strip 4 and the protective frame 3, the blade 7 can be effectively protected. If improper operation occurs, the blade 7 can also be prevented from being damaged by impact.
[0045] When the entire device falls rapidly to the ground, the two base plates 17 will be the first to contact the ground. The base plates 17 will cause the sliding block 18 to move upward, and the sliding block 18 will cause the damping rod 16 to contract. At this time, the second spring 14 will also contract due to the compression of the sliding block 18. Subsequently, under the action of the rebound force of the second spring 14, the second spring 14 will cause the sliding block 18 to move downward, thereby causing the damping rod 16 to extend. Under the action of the four damping rods 16 and the four second springs 14, the force on the two base plates 17 can be effectively buffered, thereby avoiding large vibrations to the entire device and preventing damage to the parts inside the body 1.
[0046] Example 2:

[0049] Two sliding grooves 9 are provided, both of which are located within the E-shaped frame 2. Slider 11 is slidably installed within the sliding grooves 9. The ends of the two sliders 11 that are far apart pass through the ends of the two sliders 11 and extend into the two limiting blocks 8 respectively. An L-shaped rod 13 is fixedly installed on the opposite side of each of the two sliders 11. A groove 12 is provided within the E-shaped frame 2 between the two sliding grooves 9. The opposite ends of the two L-shaped rods 13 pass through the opposite side of each of the two sliding grooves 9 and extend into the groove 12. A first spring 10 is fitted on the L-shaped rod 13 within the sliding groove 9.
[0050] First, the worker presses down on the two L-shaped rods 13 on the E-shaped frame 2, bringing them closer together.

Then, the worker inserts the two limiting blocks 8 at the bottom of the protective frame 3 into the two through grooves 6 on the E-shaped frame 2, and then releases their hand. Under the action of the rebound force of the two first springs 10, the two first springs 10 will drive the two sliders 11 away from each other until the ends of the two sliders 11 that are far apart are inserted into the two limiting blocks 8. At this time, the protective frame 3 will be fixed on the E-shaped frame 2.
[0051] Example 3:
[0052] This embodiment provides a mobile hexacopter unmanned aerial vehicle (UAV) that, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0053] In this embodiment, one end of the slider 11 is inserted into the corresponding limiting block 8, the L-shaped rod 13 is slidably connected to the corresponding slide groove 9 and the corresponding E-shaped frame 2, and the two ends of the first spring 10 are tightly welded to the inner wall of the slide groove 9 and the end of the slider 11 near the groove 12, respectively.
[0054] Specifically, it is ensured that one end of the slider 11 can be inserted into the limiting block 8, that the L-shaped rod 13 can slide in the slide groove 9 and the E-shaped frame 2, and that the structure of the first spring 10 is stable.
[0055] Example 4:
[0056] This embodiment provides a mobile hexacopter unmanned aerial vehicle (UAV) that, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0057] In this embodiment, the protective frame 3 and the limiting block 8 are integrally formed, and the sliding block 18 and the base plate 17 are integrally formed.
[0058] This ensures the structural stability between the protective frame 3 and the limiting block 8, and guarantees the structural stability between the sliding block 18 and the base plate 17.
[0059] Example 5:
[0060] This embodiment provides a mobile hexacopter unmanned aerial vehicle (UAV) that, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0061] In this embodiment, the two ends of the second spring 14 are fixedly connected to the top of the sliding block 18 and the inner wall of the limiting groove 15, respectively, and the sliding block 18 is slidably connected to the limiting groove 15.
[0062] This ensures the structural stability of the second spring 14 and guarantees that the sliding block 18 can slide within the limiting groove 15.
[0063] Example 6:
[0064] This embodiment provides a mobile hexacopter unmanned aerial vehicle (UAV) that, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0065] In this embodiment, the two E-shaped frames 2 are arranged symmetrically.
[0066] The two E-shaped frames 2 are symmetrically arranged to ensure that the whole device can operate normally.
[0067] Working principle: During installation, the worker first presses down on the two L-shaped rods 13 on the E-shaped frame 2, bringing them closer together. At this time, the first spring 10 will contract under the pressure of the slider 11 until the slider 11 moves out of the through groove 6 and fully enters the slide groove 9. Then, the worker inserts the two limiting blocks 8 at the bottom of the protective frame 3 into the two through grooves 6 on the E-shaped frame 2, and then releases their hand. Under the rebound force of the two first springs 10, the two first springs 10 will drive the two sliders 11 away from each other until... The two sliders 11 are inserted into the two limiting blocks 8 at opposite ends. At this time, the protective frame 3 will be fixed on the E-shaped frame 2. The three blades 7 on the E-shaped frame 2 will be located in the three round holes on the protective frame 3. The protective strip 4 inside the protective frame 3 will be located above the corresponding blade 7, thus protecting the blade 7. After both protective frames 3 are installed, they can be used. Under the action of the protective strip 4 and the protective frame 3, the blade 7 can be effectively protected. If improper operation occurs, the blade 7 can also be prevented from being damaged by impact.
[0068] When the entire device falls rapidly to the ground, the two base plates 17 will be the first to contact the ground. The base plates 17 will cause the sliding block 18 to move upward, and the sliding block 18 will cause the damping rod 16 to contract. At this time, the second spring 14 will also contract due to the compression of the sliding block 18. Subsequently, under the action of the rebound force of the second spring 14, the second spring 14 will cause the sliding block 18 to move downward, thereby causing the damping rod 16 to extend. Under the action of the four damping rods 16 and the four second springs 14, the force on the two base plates 17 can be effectively buffered, thereby avoiding large vibrations to the entire device and preventing damage to the parts inside the body 1.
