Description

Technical Field

[0001] The utility model relates to the field of electric cylinders, in particular to a high-silence electric cylinder for unmanned aerial vehicles. Background Art

[0002] An electric cylinder is an actuator that converts electrical energy into mechanical energy to achieve linear reciprocating motion. It converts the motor's rotational motion into linear motion of the push rod through a built-in servo motor that drives the screw (usually a ball screw or roller screw).

[0003] Currently, when using a camera for shooting, it is usually necessary to mount the camera on a drone through an electric cylinder, so that the camera can move linearly on the drone through the electric cylinder to meet the needs of specific shooting tasks. However, when the electric cylinder is poorly lubricated, it will cause increased friction and generate noise. It is difficult for existing devices to improve the noise generated.

[0004] Therefore, in order to solve the above problems, a highly silent electric cylinder for drones has been developed, which can lubricate and insulate the telescopic cylinder to reduce noise. Utility Model Content

[0005] In order to overcome the shortcoming that the existing device is difficult to improve the noise generated, the utility model provides a high-silence electric cylinder for drones that can lubricate and isolate the telescopic cylinder to reduce noise.

[0006] The technical solution is: a high-silence electric cylinder for unmanned aerial vehicles, including a mounting frame, a first fixed frame, a motor, a telescopic cylinder, a lubrication mechanism and a sound insulation mechanism. The first fixed frame is connected to the lower side of the mounting frame, the motor is connected to the lower left side of the first fixed frame, and the telescopic cylinder is connected to the lower right side of the first fixed frame. The telescopic cylinder is provided with a lubrication mechanism for lubrication, and the first fixed frame is provided with a sound insulation mechanism for isolation.

[0007] As an improvement of the above solution, a mounting hole is provided on the first fixing frame.

[0008] As an improvement of the above scheme, the lubrication mechanism includes a second fixed frame, a material storage bottle, a feed pipe, a ring and balls. The lower part of the telescopic cylinder is connected to the second fixed frame, the right part of the second fixed frame is connected to the material storage bottle, the lower side of the material storage bottle is connected to the feed pipe, the telescopic cylinder is connected to the ring, the feed pipe is connected to the ring, and a plurality of balls are rotatably connected to the ring. The lubricating oil in the material storage bottle is transported to the ring through the feed pipe to lubricate the balls, thereby reducing friction and reducing the noise generated by the telescopic cylinder when it is running.

[0009] As an improvement of the above scheme, the sound insulation mechanism includes a sound insulation cover, a limiting plate, a support plate and a rotating frame. The sound insulation cover is clamped on the first fixed frame, and limiting plates are connected to the left and right sides of the upper part of the sound insulation cover. The left and right sides of the first fixed frame are connected to the support plates, and the supporting plates are rotatably connected to the rotating frame. The rotating frame is rotated to align with the alignment holes on the limiting plate. After the sound insulation cover is clamped with the first fixed frame, the rotating frame is rotated to reset and clamped with the limiting plate, thereby fixing and limiting the sound insulation cover.

[0010] As an improvement to the above solution, a stopper is provided on the rotating frame.

[0011] The beneficial effects of the utility model are as follows: the utility model isolates noise through the soundproof cover, and transports the lubricating oil in the storage bottle to the ring through the feed pipe, thereby reducing the friction between the balls, and can lubricate and isolate the telescopic cylinder, thereby reducing the noise.

[0017] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0018] A highly silent electric cylinder for drones, such as Figure 1 and Figure 2As shown, it includes a mounting frame 3, a first fixed frame 4, a motor 5, a telescopic cylinder 6, a lubricating mechanism 7 and a sound insulation mechanism 8. The mounting frame 3 is connected to the first fixed frame 4 at the lower side, the motor 5 is connected to the lower left side of the first fixed frame 4, the telescopic cylinder 6 is connected to the lower right side of the first fixed frame 4, the lubricating mechanism 7 is provided on the telescopic cylinder 6, and the sound insulation mechanism 8 is provided on the first fixed frame 4.

[0019] like Figure 2 and Figure 3 As shown, the lubrication mechanism 7 includes a second fixed frame 71, a material storage bottle 72, a feed pipe 73, a ring 74 and a ball 75. The lower part of the telescopic cylinder 6 is connected to the second fixed frame 71, the right part of the second fixed frame 71 is connected to the material storage bottle 72, the lower side of the material storage bottle 72 is connected to the feed pipe 73, the telescopic cylinder 6 is connected to the ring 74, the feed pipe 73 is connected to the ring 74, and eight balls 75 are rotatably connected to the ring 74.

[0020] like Figure 1 and Figure 4 As shown, the sound insulation mechanism 8 includes a sound insulation cover 81, a limiting plate 82, a support plate 83 and a rotating frame 84. The sound insulation cover 81 is clamped on the first fixed frame 4, and the limiting plates 82 are connected to the left and right sides of the upper part of the sound insulation cover 81. The left and right sides of the first fixed frame 4 are connected to the support plates 83, and the rotating frame 84 is rotatably connected to the support plates 83.

[0021] When the utility model is in use, it is first necessary to control the utility model to move to the operating area, and then rotate the rotating frame 84 to align with the alignment hole on the limiting plate 82. After the soundproof cover 81 is engaged with the first fixed frame 4, the rotating frame 84 is rotated to reset and engage with the limiting plate 82, thereby fixing and limiting the soundproof cover 81. Then, the camera is mounted on the telescopic end of the telescopic cylinder 6, and the telescopic cylinder 6 is controlled to drive the camera to move in a straight line under the action of the motor 5, so as to facilitate shooting of places that the drone 1 cannot penetrate, so as to meet the needs of specific shooting tasks. When the equipment is running, the noise is isolated by the soundproof cover 81 to reduce the impact of the noise. At the same time, the lubricating oil in the storage bottle 72 is transported to the ring 74 through the feed pipe 73 to lubricate the ball 75, reduce friction, and thus reduce the noise generated by the telescopic cylinder 6 when it is running.

[0022] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
