Technical Field
[0001] The utility model relates to the field of UAV protection devices, in particular to a UAV structure with a take-off and landing protection device. Background Art
[0002] An unmanned aerial vehicle (UAV) is a crewless aircraft that can fly through remote control or autonomous programming. A UAV usually consists of a flight platform, a control system, and a payload.
[0003] People often use UAVs to perform various tasks, such as reconnaissance, surveillance, agricultural spraying, environmental monitoring, disaster relief, etc. However, when operating a UAV to land outdoors, it is difficult to find a flat landing point, which may cause the UAV to tilt or tip over due to the rough landing point, resulting in damage to the airframe. Therefore, a UAV structure with a take-off and landing protection device is proposed to solve the above problems. Summary of the Utility Model
[0004] In order to make up for the deficiencies of the prior art and solve the problem that when operating a UAV to land outdoors, it is difficult to find a flat landing point, which may cause the UAV to tilt or tip over due to the rough landing point, resulting in damage to the airframe, the utility model proposes a UAV structure with a take-off and landing protection device.
[0005] The technical solution adopted by the utility model to solve its technical problems is as follows: A UAV structure with a take-off and landing protection device according to the utility model includes a UAV main body; power devices are uniformly installed on the side wall of the UAV main body, a control system is fixedly installed on the top end of the UAV main body, and a shaping component is arranged at the bottom end of the UAV main body.
[0006] The shaping component includes a push rod arranged at the bottom end of the UAV main body. The push rod is uniformly and slidably installed on the inner wall of the bottom end of the UAV main body. Fixed components are arranged at the bottom ends of the push rods. Shaping outer shells are slidably installed on the outer walls of the push rods. Shaping round rods are slidably installed on the inner walls of the shaping outer shells. Contact components are arranged at the bottom ends of the shaping round rods. Auxiliary components are arranged at the top ends of the shaping round rods. It can avoid the problem that when operating a UAV to land outdoors, it is difficult to find a flat landing point, which may cause the UAV to tilt or tip over due to the rough landing point, resulting in damage to the airframe, improve the adaptability of the UAV, thus improving the stability of the UAV during landing and extending the service life of the UAV.
[0007] Preferably, the abutting component includes a spherical ball arranged at the bottom end of the shaping round rod, and abutting blocks are rotatably installed on the outer walls of the spherical balls. The radius of the cross-section of the sliding groove opened at the top end of the abutting block is smaller than the radius of the maximum cross-section of the spherical ball; this can prevent a gap from existing between the bottom end of the drone and the uneven ground when the drone lands, which may lead to a decrease in the stability of the drone during landing, resulting in the drone tilting or tipping over. This further improves the adaptability of the drone and the stability during landing, thereby enhancing the reliability and service life of the drone.
[0008] Preferably, the fixing component includes an airtight block arranged at the bottom end of the push rod. The airtight blocks all abut against the inner walls of the airtight grooves, and the airtight grooves are all opened on the inner walls of the shaping outer shell. The top ends of the push rods are all fixedly installed with extrusion plates, and a lead screw is threadedly installed on the inner wall of the extrusion plate. The bottom end of the lead screw is rotatably installed at the bottom end of the drone body, and the top end of the lead screw is fixedly installed with a motor; this can prevent the shaping round rod from easily moving after the drone has landed, which may cause uneven stress on the drone and result in tilting or tipping over. It improves the stability of the drone after landing, thereby extending the service life of the drone.
[0009] Preferably, the auxiliary component includes a first driving rod arranged at the top end of the shaping round rod. The top ends of the first driving rods are all rotatably installed with telescopic rods. One ends of the telescopic rods all pass through the shaping outer shell and extend to the outer wall of the shaping outer shell. The ends of the telescopic rods extending to the outer wall of the shaping outer shell are all rotatably installed with second driving rods, and auxiliary rods are slidably installed at the bottom ends of the second driving rods; the shaping round rod can drive the first driving rod to move, so that the first driving rod drives the auxiliary rod to move through the telescopic rod and the second driving rod, causing the auxiliary rod to abut against the ground and extend into the ground, further improving the stability of the drone during landing.
[0010] Preferably, springs are installed at the bottom ends of the second driving rods, and the second driving rods and the auxiliary rods are all connected by springs; this can prevent the auxiliary rod from being difficult to extend into the ground when the landing point is relatively firm, which may cause the auxiliary rod to hinder the landing of the drone and result in movement interference problems, improving the stability and reliability of the device.
[0011] Preferably, limiting blocks are symmetrically and fixedly installed on the outer walls of the second driving rods, and the limiting blocks are all slidably installed on the inner walls of the limiting grooves, and the limiting grooves are all opened on the inner walls of the auxiliary rods; this can prevent the auxiliary rod from moving downward under the influence of gravity when the drone is in flight, causing the auxiliary rod to drive the spring to undergo elastic deformation and accumulate elastic potential energy, thus keeping the spring in a stretched state and reducing the service life of the spring, improving the service life of the spring.
[0012] Preferably, the radius of the largest cross-section of the airtight block is greater than the radius of the cross-section of the push rod, and the distance between the top end and the bottom end of the airtight block is less than the distance between the top end and the bottom end of the lead screw; this can prevent the airtight block from being not tightly in contact with the airtight groove, thereby reducing the fixing effect on the shaping round rod and causing problems such as the tilt and overturn of the drone, and improving the stability and reliability of the device.
[0013] The beneficial effects of the present utility model are as follows:
[0014] 1. By setting the shaping component, when the drone lands, the shaping outer shell and the shaping round rod can automatically adjust their lengths according to the actual situation of the landing point, so as to keep the drone body horizontal, avoiding the problem that it is difficult to find a flat landing point when operating the drone to land outdoors, resulting in the drone being prone to tilt and overturn due to rough landing points, thereby causing damage to the airframe. This improves the adaptability of the drone, enhances the stability of the drone during landing, and extends the service life of the drone;
[0015] 2. By setting the auxiliary component, when the shaping component is shaping, the shaping round rod drives the first driving rod to move, so that the first driving rod drives the auxiliary rod to move through the telescopic rod and the second driving rod, making the auxiliary rod abut against the ground and extend underground, further improving the stability of the drone during landing.

Specific implementation mode
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] Embodiment 1
[0025] Please refer to Figures 1-5 As shown, a drone structure with a takeoff and landing protection device includes the main body 1 of the drone; power devices 2 are uniformly installed on the side wall of the main body 1 of the drone, a control system 3 is fixedly installed at the top end of the main body 1 of the drone, and a shaping component is arranged at the bottom end of the main body 1 of the drone;
[0026] The shaping component includes a push rod 4 arranged at the bottom end of the main body 1 of the drone. The push rod 4 is uniformly and slidably installed on the inner wall of the bottom end of the main body 1 of the drone. Fixed components are arranged at the bottom ends of the push rods 4. Shaping shells 5 are slidably installed on the outer walls of the push rods 4. Shaping round rods 6 are slidably installed on the inner walls of the shaping shells 5. Abutting components are arranged at the bottom ends of the shaping round rods 6, and auxiliary components are arranged at the top ends of the shaping round rods 6; By setting the shaping component, when the drone takes off and lands, the lengths of the shaping shell 5 and the shaping round rod 6 can be automatically adjusted according to the actual situation of the landing point, so as to keep the main body 1 of the drone horizontal, avoiding the problem that when operating the drone to take off and land outdoors, it is difficult to find a flat landing point, resulting in the drone being prone to tilt and overturn due to the rugged landing point, thus causing damage to the fuselage, improving the adaptability of the drone, thereby improving the stability of the drone during takeoff and landing, and extending the service life of the drone.
[0027] Please refer to Figures 1-3As shown in the figure, the abutting component includes a spherical ball 7 provided at the bottom end of the shaping round rod 6. The outer walls of the spherical ball 7 are all rotatably installed with abutting blocks 8. The cross-sectional radius of the sliding groove opened at the top end of the abutting block 8 is smaller than the radius of the largest cross-section of the spherical ball 7. By providing the abutting component, when the drone lands, the abutting block 8 abuts against the ground. By rotating the abutting block 8 around the spherical ball 7, the abutting block 8 can be made to closely adhere to the ground, avoiding the problem that when the drone lands, there is a gap between the bottom end of the drone and the uneven ground, resulting in a decrease in the stability of the drone during landing, and thus causing the drone to tilt or tip over. This further improves the adaptability of the drone and the stability during landing, thereby improving the reliability and service life of the drone.
[0028] Please refer to Figures 2-4 As shown in the figure, the fixing component includes an airtight block 9 provided at the bottom end of the push rod 4. The airtight blocks 9 all abut against the inner walls of the airtight grooves 10. The airtight grooves 10 are all opened on the inner wall of the shaping outer shell 5. The top ends of the push rods 4 are all fixedly installed with pressing plates 11. The inner wall of the pressing plate 11 is threadedly installed with a lead screw 12. The bottom end of the lead screw 12 is rotatably installed at the bottom end of the drone body 1. The top end of the lead screw 12 is fixedly installed with a motor 13. By providing the fixing component, after the shaping component completes shaping according to the landing point situation, the motor 13 can be started, so that the motor 13 drives the airtight block 9 to abut against the inner wall of the airtight groove 10 through the lead screw 12, the pressing plate 11 and the push rod 4, so that the cavity between the shaping outer shell 5 and the shaping round rod 6 forms air pressure, thereby fixing the position of the shaping round rod 6, avoiding the problem that when the drone completes landing, the shaping round rod 6 is prone to move, resulting in uneven force on the drone, and thus causing the drone to tilt or tip over, improving the stability of the drone after landing, and thus extending the service life of the drone.
[0029] In summary, through the cooperation of the shaping component, the abutting component and the fixing component, when the drone needs to land, first, the bottom end of the drone is closely abutted against the ground through the abutting component, then the level of the drone body 1 is ensured through the shaping component, and finally the shaping component is fixed through the fixing component, thereby improving the stability of the drone during landing.
[0030] Embodiment 2
[0031] Please refer to Figures 1-5As shown, as another implementation mode of the present utility model compared with the first comparative example, the auxiliary component includes a first driving rod 14 arranged at the top end of the shaping round rod 6. The top ends of the first driving rods 14 are all rotatably installed with telescopic rods 15. One ends of the telescopic rods 15 all pass through the shaping outer shell 5 and extend to the outer wall of the shaping outer shell 5. One ends of the telescopic rods 15 extending to the outer wall of the shaping outer shell 5 are all rotatably installed with second driving rods 16. The bottom ends of the second driving rods 16 are all slidably installed with auxiliary rods 17. By setting the auxiliary component, when the shaping component performs shaping, the shaping round rod 6 drives the first driving rod 14 to move, so that the first driving rod 14 drives the auxiliary rod 17 to move through the telescopic rod 15 and the second driving rod 16, so that the auxiliary rod 17 abuts against the ground and extends underground, further improving the stability of the drone when landing and taking off.
[0032] Please refer to Figures 2-4 As shown, springs 18 are installed at the bottom ends of the second driving rods 16. The second driving rods 16 and the auxiliary rods 17 are all connected by the springs 18. When the landing point is relatively firm, the second driving rod 16 can squeeze the spring 18, and the spring 18 undergoes elastic deformation to accumulate elastic potential energy, avoiding the problem that when the landing point is relatively firm, it is difficult for the auxiliary rod 17 to extend underground, resulting in the auxiliary rod 17 hindering the landing and takeoff of the drone and causing movement interference, and improving the stability and reliability of the device.
[0033] Please refer to Figure 5 As shown, limiting blocks 19 are symmetrically and fixedly installed on the outer walls of the second driving rods 16. The limiting blocks 19 are all slidably installed on the inner walls of the limiting grooves 20. The limiting grooves 20 are all opened on the inner walls of the auxiliary rods 17. Before the drone lands and takes off, the limiting blocks 19 can abut against the top ends of the limiting grooves 20 to prevent the auxiliary rods 17 from moving downward, avoiding the problem that when the drone is in flight, the auxiliary rods 17 move downward under the influence of gravity, causing the auxiliary rods 17 to drive the springs 18 to undergo elastic deformation and accumulate elastic potential energy, so that the springs 18 are kept in a stretched state, resulting in a reduced service life of the springs 18, and improving the service life of the springs 18.
[0034] Please refer to Figures 2-4 As shown, the radius of the maximum cross-section of the airtight block 9 is greater than the radius of the cross-section of the push rod 4, and the distance between the top end and the bottom end of the airtight block 9 is less than the distance between the top end and the bottom end of the lead screw 12. When the abutting block 8 does not abut against the ground, the top end of the airtight block 9 can abut against the top end of the inner wall of the shaping outer shell 5, so that the shaping outer shell 5 is kept at the bottom end of the drone body 1. By setting the radius of the maximum cross-section of the airtight block 9 to be greater than the radius of the cross-section of the push rod 4, the problem that the airtight block 9 is likely to be in poor contact with the airtight groove 10, thereby reducing the fixing effect on the shaping round rod 6 and causing the drone to tilt or overturn is avoided, and the stability and reliability of the device are improved.
[0035] Working principle: When the drone needs to land, the drone is controlled to move towards the ground. The abutting block 8 abuts against the ground, causing the abutting block 8 to rotate around the spherical ball 7, so that the abutting block 8 clings to the ground. At the same time, the abutting block 8 pushes the spherical ball 7 to move, the spherical ball 7 pushes the shaping round rod 6 to move, and at the same time, the shaping round rod 6 drives the first driving rod 14 to move. The first driving rod 14 drives the telescopic rod 15 to rotate, so that the telescopic rod 15 drives the second driving rod 16 to move towards the end far from the first driving rod 14. The second driving rod 16 squeezes the spring 18, causing the spring 18 to accumulate elastic potential energy and undergo elastic deformation. The spring 18 then drives the auxiliary rod 17 to move. After all the shaping round rods 6 have been displaced, the motor 13 is started, causing the motor 13 to drive the lead screw 12 to rotate. The lead screw 12 drives the pressing plate 11 to move towards the bottom end of the drone body 1. The pressing plate 11 drives the push rod 4 to move, and the push rod 4 drives the airtight block 9 to move, so that the airtight block 9 abuts against the inner wall of the airtight groove 10, thereby forming air pressure between the shaping outer shell 5 and the shaping round rod 6 to fix the position of the shaping round rod 6, thus improving the stability of the drone during landing.
