The turntable is connected to the RV gearbox and rotates around the same axis. The eccentric shaft is parallel to the turntable axis and eccentrically positioned on the turntable. The connecting rod is perpendicular to the eccentric shaft, with its top end rotatably mounted on it along the eccentric shaft axis. The output mechanism includes an output rod rotatably connected to the bottom of the connecting rod and a guide block sleeved on the outside of the output rod to guide its linear movement. The housing includes a rotating part sleeved outside the transmission mechanism and a telescopic part sleeved outside the output mechanism.

[0006] Preferably, the rotating part has an inwardly recessed mounting groove on the side away from the RV gearbox. The transmission mechanism also includes a rotating shaft and a bearing. The rotating shaft is mounted on the eccentric shaft, coaxially arranged with the turntable, and can extend into the mounting groove.

The connecting rod passes through the clearance hole and is rotatably connected to the output rod.

[0009] Preferably, it further includes a connecting shaft disposed between the output rod and the linkage rod to rotatably connect the two. The top surface of the output rod is recessed to form a groove into which the linkage rod can extend. Rotation holes are formed through both sides of the groove.

Detailed Implementation

[0019] The present invention will be further described below through specific embodiments.

[0020] Reference Figures 1 to 4 As shown, a compact electric output device includes a servo motor 1, an RV gearbox 2, a transmission mechanism 3, an output mechanism 4, and a housing 5.

[0021] Servo motor 1 is connected to one side of RV gearbox 2.

[0022] The transmission mechanism 3 is connected to the other side of the RV gearbox 2 and includes a turntable 31, an eccentric shaft 32 and a connecting rod 33. The turntable 31 is connected to the RV gearbox 2 and rotates around the same axis. The axis of the eccentric shaft 32 is parallel to the axis of the turntable 31 and is eccentrically mounted on the turntable 31. The connecting rod 33 is perpendicular to the eccentric shaft 32 and its top end is rotatably mounted on the eccentric shaft 32 along the axis of the eccentric shaft 32.

[0023] The output mechanism 4 includes an output rod 41 rotatably connected to the bottom of the linkage 33 and a guide block 42 sleeved on the outside of the output rod 41 to guide the linear movement of the output rod 41.

[0024] The housing 5 includes a rotating part 51 fitted outside the transmission mechanism 3 and a telescopic part 52 fitted outside the output mechanism 4. The rotating part 51 and the telescopic part 52 are detachably connected, and a clearance hole 53 is formed at the connection point for the connecting rod 33 to pass through. The connecting rod 33 passes through the clearance hole 53 and is rotatably connected to the output rod 41. The width of the clearance hole 53 is greater than the left and right swing range of the connecting rod 33. The rotating part 51 has a mounting hole 54 formed on the side near the servo motor 1 for the RV gearbox 2 to pass through and be embedded in the rotating part 51. By using an embedded structure to assemble the RV gearbox 2 in the housing 5, precise control of the extension of the output rod 41 is achieved, while the structure is more compact, making the device smaller and easier to adapt to more usage environments. The rotating part 51 has an inwardly recessed mounting groove 55 on the side away from the RV gearbox 2. The transmission mechanism 3 also includes a rotating shaft 34 and a bearing 35. The rotating shaft 34 is mounted on the eccentric shaft 32, coaxially arranged with the turntable 31, and can extend into the mounting groove 55. The bearing 35 is located between the rotating shaft 34 and the mounting groove 55, eliminating the need for an additional bearing 35 seat and further reducing the size of the device.

[0025] Specifically, the guide block 42 is disposed on the bottom surface of the telescopic part 52, and a guide hole 43 is formed thereon for the output rod 41 to pass through. The axis of the guide hole 43 is perpendicular to the axis of the eccentric shaft 32. The bottom of the telescopic part 52 is formed with a through hole 56 opposite to the guide hole 43 and for the output rod 41 to extend out. The guide block 42 extends outward to form an extension section 44, and a plurality of fixing holes 45 for fixing devices are formed on the extension section 44.

[0026] Furthermore, it also includes a connecting shaft 36 disposed between the output rod 41 and the linkage rod 33 to rotatably connect the two. The top surface of the output rod 41 is recessed to form a groove 37 into which the linkage rod 33 can extend. Rotation holes 38 are formed through both sides of the groove 37. The bottom of the linkage rod 33 is formed with a positioning hole 39 corresponding to the rotation hole 38. The connecting shaft 36 passes through the rotation hole 38 and the positioning hole 39 in sequence and is disposed therein.

[0027] This application uses a servo motor 1 to drive the eccentric shaft 32 to rotate, and then the rotation of the turntable 31 causes the connecting rod 33 to drive the output rod 41 to move up and down. While moving up and down, the output rod 41 is guided by the guide block 42 to perform a linear motion. The extension of the output rod 41 can be precisely controlled by the servo motor 1, improving the accuracy of the device. At the same time, this application adopts an embedded structure to assemble the RV gearbox 2 in the housing 5, making the structure more compact and the device smaller, which is easier to adapt to a wider range of usage environments and has high practicality.

[0028] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
