Abstract
Description
Technical Field
[0001] The present application relates to the technical field of unmanned aerial vehicles, and more specifically, to a camera protection structure for a through-the-aircraft vehicle. Background Art
[0002] A FPV is a type of UAV, which can reach a maximum speed of 120km / h to 230km / h. Due to its extremely high speed, it is very easy to collide. Also, the camera of a FPV is usually a wide-angle lens. In order to avoid the rotor cover blocking the field of view, the camera cannot be too recessed into the rotor cover. Therefore, the camera is poorly protected and easily damaged. Utility Model Content
[0003] In order to make up for the above deficiencies, the present application provides a camera protection structure for a FPV, aiming to improve the problems mentioned in the above background technology.
[0004] An embodiment of the present application provides a camera protection structure for a flying drone, including a drone body, wherein rotor covers are arranged at four corners of the drone body, a camera is arranged at the front end of the drone body, the camera is recessed in the rotor covers on both sides, and retaining frames are arranged on both sides of the camera, the retaining frames are elastically connected to the drone body, a limiting member is arranged on the drone body to limit the retaining frame, and an acceleration sensor is arranged in the drone body to interact with the limiting member.
[0005] In a specific implementation manner, the retaining frame is a hollow structure, protrusions are provided at both ends of the retaining frame, and a slide groove adapted to the protrusions is provided on the drone body.
[0006] In the above implementation process, the hollow structure of the baffle has good elasticity and can also reduce weight, thereby reducing the impact on the flight performance of the Flying Drone. The protrusion moves in the slide groove and plays a basic limiting role.
[0007] In a specific embodiment, a spring is provided at the inner end of the retaining frame.
[0008] In the above implementation process, during flight, the baffle is retracted into the drone body and the spring is compressed. When a collision occurs, the limiter releases the restriction on the baffle and the spring pushes the baffle out to protect the camera.
[0009] In a specific implementation manner, a guide rod is fixedly connected to the inner end of the retaining frame, the guide rod is slidably connected to the drone body, and the spring is sleeved on the guide rod.
[0010] In the above implementation process, the guide rod can stabilize the movement trajectory of the baffle frame, improve the structural strength of the baffle frame, and can also constrain the spring to prevent the spring from bending and failing.
[0011] In a specific implementation, the limiting member includes a stop block and a rocker arm, the stop block is fixedly connected to the retaining frame, the rocker arm is rotatably connected to the drone body, and the front end of the rocker arm is movably pressed against the stop block.
[0012] In the above implementation process, when the retaining frame is retracted into the drone body, the front end of the rocker arm abuts against the stop block to prevent the retaining frame from popping out. When a collision occurs, the rocker arm deflects downward until it leaves the stop block, and the retaining frame can pop out normally.
[0013] In a specific implementation manner, the front end of the rocker arm is in a hook shape, and the retaining frame is provided with a hook groove adapted to the hook shape.
[0014] In the above implementation process, when a collision occurs, the rocker arm deflects downward and slides against the lower side of the baffle until the baffle is completely popped out. The curved hook of the rocker arm is embedded in the hook groove to lock the baffle, preventing the baffle from retracting due to impact, thereby effectively protecting the camera.
[0015] In a specific implementation, the limiting member further includes a motor, and an output end of the motor is connected to the rocker arm shaft.
[0016] In a specific implementation, the motor is double-ended, and two output ends of the motor are axially connected to a rocker arm respectively.
[0017] In the above implementation process, after receiving the signal from the acceleration sensor, the servo-controlled motor drives the two rocker arms to deflect at the same time, and then drives the two guard frames to pop out from both sides of the camera, thereby protecting the camera. In another embodiment, a structure similar to a guard frame, a spring and a limit member is also installed on the camera. When a collision occurs, the guard frame pops out and the camera quickly retracts, thereby achieving better protection.
[0018] Compared with the prior art, the beneficial effects of the present application are: using an acceleration sensor to sense the impact on the rotor cover and triggering the limiter to contact the limit on the frame, the frame pops up under the action of elastic force, protecting both sides of the camera to prevent the camera from being directly hit; during normal flight, the limiter restricts the frame within the drone body to prevent the frame from blocking the camera's field of view.

[0025] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.
[0026] See also Figure 1-Figure 4 The present application provides a camera protection structure for a flying drone, including a drone body 10, wherein the four corners of the drone body are provided with a rotor cover 30, a camera 20 is provided at the front end of the drone body 10, the camera 20 is recessed in the rotor cover 30 on both sides, and a retaining frame 40 is provided on both sides of the camera 20, the retaining frame 40 is elastically connected to the drone body 10, a limiting member 50 is provided on the drone body 10 to limit the retaining frame 40, and an acceleration sensor is provided in the drone body 10 to be linked with the limiting member 50. The acceleration sensor is used to sense the impact on the rotor cover 30, and the limiting member 50 is triggered to contact the retaining frame 40. The retaining frame 40 pops up under the action of elastic force to protect the two sides of the camera 20, so as to prevent the camera 20 from being directly impacted. During normal flight, the limiting member 50 limits the retaining frame 40 in the drone body 10, so as to prevent the retaining frame 40 from blocking the field of view of the camera 20.
[0027] See also Figure 1-Figure 4 The retaining frame 40 is a hollow structure, and protrusions 60 are arranged at both ends of the retaining frame 40. The drone body 10 is provided with a slide groove adapted to the protrusions 60. The retaining frame 40 of the hollow structure has good elasticity, and can also reduce weight and reduce the impact on the flight performance of the drone. The protrusions 60 move in the slide groove and play a basic limiting role.
[0028] See also Figure 1-Figure 4, a spring 70 is arranged at the inner end of the retaining frame 40. During flight, the retaining frame 40 is retracted into the drone body 10 and compresses the spring 70. When a collision occurs, the limiter 50 releases the restriction on the retaining frame 40, and the spring 70 pushes the retaining frame 40 out to protect the camera 20.
[0029] See also Figure 1-Figure 4 The inner end of the retaining frame 40 is fixedly connected with a guide rod 80, the guide rod 80 is slidably connected to the drone body 10, and the spring 70 is sleeved on the guide rod 80. The guide rod 80 can stabilize the motion trajectory of the retaining frame 40, improve the structural strength of the retaining frame 40, and can also constrain the spring 70 to prevent the spring 70 from bending and failing.
[0030] See also Figure 1-Figure 4 The limiting member 50 includes a stopper 51 and a rocker arm 52. The stopper 51 is fixedly connected to the stopper 40, and the rocker arm 52 is rotatably connected to the drone body 10. The front end of the rocker arm 52 is movably pressed against the stopper 51. When the stopper 40 is retracted into the drone body 10, the front end of the rocker arm 52 presses against the stopper 51 to prevent the stopper 40 from popping out. When a collision occurs, the rocker arm 52 deflects downward until it leaves the stopper 51, and the stopper 40 can be normally popped out.
[0031] See also Figure 1-Figure 4 The front end of the rocker arm 52 is hook-shaped, and a hook groove matching the hook shape is provided on the blocking frame 40. When a collision occurs, the rocker arm 52 deflects downward and slides against the lower side of the blocking frame 40 until the blocking frame 40 is completely ejected, and the hook shape of the rocker arm 52 is embedded in the hook groove, locking the blocking frame 40 to prevent the blocking frame 40 from being retracted due to the collision, thereby effectively protecting the camera 20.
[0032] See also Figure 1-Figure 4 The limiter 50 also includes a motor 53, and the output end of the motor 53 is axially connected to the rocker arm 52. The motor 53 is a double-headed setting, and the two output ends of the motor 53 are axially connected to a rocker arm 52 respectively. After receiving the signal of the acceleration sensor, the servo-controlled motor 53 drives the two rocker arms 52 to deflect at the same time, and then drives the two blocking frames 40 to pop out from both sides of the camera 20, thereby protecting the camera 20. In another embodiment, the camera 20 is also equipped with a structure similar to the blocking frame 40, the spring 70 and the limiter 50. When a collision occurs, the blocking frame 40 pops out and the camera 20 also retracts quickly, which has a better protective effect.
[0033] The working principle of the camera protection structure of the cross-country drone is as follows: during flight, the blocking frame 40 is retracted into the drone body 10 and the spring 70 is compressed. The front end of the rocker arm 52 abuts against the abutment 51 to prevent the blocking frame 40 from popping out, and the field of view of the camera 20 is not blocked. When a collision occurs, the rotor cover 30 collides first, and the acceleration sensor senses the collision and triggers the motor 53 to deflect. The rocker arm 52 deflects downward and slides against the lower side of the blocking frame 40 until the blocking frame 40 is completely popped out. The curved hook of the rocker arm 52 is embedded in the hook groove to lock the blocking frame 40 to prevent the blocking frame 40 from being hit and retracted, thereby effectively protecting the camera 20. In summary, the acceleration sensor is used to sense the impact on the rotor cover 30, and the limiter 50 is triggered to contact the limit on the blocking frame 40. The blocking frame 40 pops out under the action of the elastic force and protects the two sides of the camera 20 to prevent the camera 20 from being directly hit. During normal flight, the limiter 50 limits the blocking frame 40 in the drone body 10 to prevent the blocking frame 40 from blocking the field of view of the camera 20.
