Description

Technical Field

[0001] This utility model relates to the technical field of rotor protection mechanisms for unmanned aerial vehicles (UAVs), specifically a rotor protection mechanism for UAVs. Background Technology

[0002] Rotorcraft drones fly at extremely high speeds, and their rapidly rotating rotors have tremendous destructive power. At the same time, the rotors are also very fragile; if they collide with obstacles while rotating at high speed, the blades will be damaged. Therefore, it is necessary to protect the rotors of drones.

[0003] Traditional drone rotor protection mechanisms are often installed directly and fixedly on the fuselage. When the protective cover is damaged and needs to be replaced, it is inconvenient. The fixed installation method cannot make the protective cover flexible for replacement. If the protective cover cannot be replaced in time, it will affect the normal rotation of the blades, thus affecting the normal use of the blades. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rotor protection mechanism for unmanned aerial vehicles (UAVs), which has the advantages of flexible replacement of protective covers and convenient use, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a rotor protection mechanism for unmanned aerial vehicles (UAVs), including a mounting plate, a motor installed in the inner cavity of the mounting plate, a support plate fixedly mounted on the outer wall of the mounting plate, a protective cover installed on the top of the mounting plate, a reinforcing rib fixedly mounted on the top of the protective cover, a support base fixedly mounted on the outer wall of the protective cover, blades fixedly mounted on the power output shaft of the motor, a fixed cylinder fixedly mounted on the outer wall of the support plate, a lifting rod movably sleeved in the inner cavity of the fixed cylinder, a limit rod fixedly mounted on the outer wall of the lifting rod, a pressure plate fixedly mounted on the top of the lifting rod, and a tension spring installed in the inner cavity of the fixed cylinder.

[0006] As a preferred technical solution of this utility model: the inner wall diameter of the fixed cylinder matches the outer wall diameter of the lifting rod, and the bottom of the pressure plate contacts the top of the protective cover.

[0007] As a preferred technical solution of this utility model: there are three pressure plates, and the three pressure plates are respectively installed on the top of the support plate.

[0008] As a preferred technical solution of this utility model: the two ends of the outer wall of the tension spring are respectively connected to the top of the support plate and the bottom of the lifting rod, and the tension spring is made of high carbon steel.

[0009] As a preferred technical solution of this utility model: the protective cover is made of ABS plastic, and the outer diameter of the protective cover is greater than the length of the blade.

[0010] As a preferred technical solution of this utility model: the reinforcing rib is made of carbon fiber, and the height of the protective cover is greater than the height of the blade.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The rotor protection mechanism of this UAV uses a fixed cylinder set on the top of the support plate and a tension spring set in the inner cavity of the fixed cylinder. Under the action of the tension spring, the lifting rod can be pulled, thereby causing the pressure plate to move downward and thus fixing the protective cover. After the protective cover is fixedly installed on the top of the mounting plate, it is more convenient to replace the protective cover when needed, avoiding the inconvenience of replacing the protective cover with traditional equipment.

[0013] 2. The drone uses a rotor protection mechanism. By setting a support base at the bottom of the protective cover, the support base can contact the ground after the drone lands. This improves the stability of the drone and allows for a larger contact area during landing, thus enhancing its stability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 A rotor protection mechanism for unmanned aerial vehicles (UAVs) includes a mounting plate 1, a motor 2 installed in the inner cavity of the mounting plate 1, a support plate 3 fixedly mounted on the outer wall of the mounting plate 1, a protective cover 4 installed on the top of the mounting plate 1, a reinforcing rib 5 fixedly mounted on the top of the protective cover 4, a support seat 6 fixedly mounted on the outer wall of the protective cover 4, blades 7 fixedly mounted on the power output shaft of the motor 2, a fixed cylinder 8 fixedly mounted on the outer wall of the support plate 3, a lifting rod 9 movably sleeved in the inner cavity of the fixed cylinder 8, a limit rod 11 fixedly mounted on the outer wall of the lifting rod 9, a pressure plate 10 fixedly mounted on the top of the lifting rod 9, and a tension spring 12 installed in the inner cavity of the fixed cylinder 8.

[0022] In the above structure, the support plate 3 provided on the outer wall of the mounting plate 1, and the fixed cylinder 8 and lifting rod 9 provided on the top of the support plate 3, can pull the lifting rod 9 under the action of the tension spring 12, so that the bottom of the pressure plate 10 can contact the top of the protective cover 4, thereby fixing the protective cover 4 and installing the protective cover 4 on the top of the mounting plate 1, thereby protecting the motor 2 and the blade 7.

[0023] In a preferred embodiment, the inner diameter of the fixed cylinder 8 matches the outer diameter of the lifting rod 9, and the bottom of the pressure plate 10 contacts the top of the protective cover 4.

[0024] In the above structure, the pressure plate 10 is provided on the top of the lifting rod 9. When the bottom of the pressure plate 10 contacts the top of the protective cover 4, the tension spring 12 is in a stretched state, which can exert a pulling effect on the lifting rod 9 and the pressure plate 10, so that the bottom of the pressure plate 10 contacts the top of the protective cover 4, thereby achieving the effect of fixing the protective cover 4.

[0025] In a preferred embodiment, there are three pressure plates 10, and the three pressure plates 10 are respectively installed on the top of the support plate 3.

[0026] In the above structure, the pressure plate 10 set on the top of the support plate 3 is pulled by the tension spring 12 so that the bottom of the pressure plate 10 comes into contact with the top of the protective cover 4, thereby pulling the pressure plate 10 and fixing the protective cover 4, thus protecting the blade 7 under the action of the protective cover 4.

[0027] In a preferred embodiment, the two ends of the outer wall of the tension spring 12 are connected to the top of the support plate 3 and the bottom of the lifting rod 9, respectively, and the tension spring 12 is made of high carbon steel.

[0028] In the above structure, the tension spring 12 installed in the inner cavity of the fixed cylinder 8 can pull the lifting rod 9 under the traction of the tension spring 12, so that the bottom of the pressure plate 10 contacts the top of the protective cover 4, thereby fixing the protective cover 4 and ensuring the stability of the protective cover 4 during use.

[0029] In a preferred embodiment: the protective cover 4 is made of ABS plastic, and the outer diameter of the protective cover 4 is greater than the length of the blade 7.

[0030] In the above structure, the protective cover 4 installed on the top of the mounting plate 1 can protect the blade 7. When the motor 2 drives the blade 7 to rotate, it can protect the blade 7 and ensure that the blade 7 is not damaged during rotation, so that the blade 7 can rotate more stably.

[0031] In a preferred embodiment, the reinforcing rib 5 is made of carbon fiber, and the height of the protective cover 4 is greater than the height of the blade 7.

[0032] In the above structure, the reinforcing ribs 5 provided on the outer wall of the protective cover 4 can support the protective cover 4 under the action of the reinforcing ribs 5, thereby ensuring the strength of the protective cover 4 and better protecting and supporting the motor 2 and blade 7 under the action of the protective cover 4.

[0033] Working principle: During the use of the above equipment, when it is necessary to install the protective cover 4, the pressure plate 10 is pulled, causing the pressure plate 10 to move upward and the lifting rod 9 to move upward along the inner wall of the fixed cylinder 8, thereby stretching the tension spring 12. At this time, the protective cover 4 can be installed. When the protective cover 4 is installed on the top of the mounting plate 1, the pressure plate 10 is released. At this time, the pressure plate 10 is pulled under the action of the tension spring 12, so that the bottom of the pressure plate 10 contacts the bottom of the protective cover 4, thereby fixing the protective cover 4. Under the action of the protective cover 4, the blade 7 is protected, preventing the blade 7 from being damaged during rotation. When it is necessary to replace the protective cover 4, the pressure plate 10 is pulled upward in the same way, so that the bottom of the pressure plate 10 is detached from the top of the protective cover 4, thereby releasing the fixation of the protective cover 4 and replacing the protective cover 4.
