[0003] Most of the existing power output devices have a direct connection between the output shaft and the input shaft. There are also cases where the input shaft drives multiple output shafts through gears, and the input power of the input shaft drives multiple output shafts to output power simultaneously. However, no matter which type of power output device, it is either a small-power device driving a small-power device through the power output device or a large-power device driving a large-power device through the power output device. Currently, it is impossible to drive a large-power device with a small-power device.

[0004] Therefore, in view of the above-described technical problems, the applicant has studied and designed a power output device that can drive a large-power device with a small-power device in combination with the structure of the existing power output device. Content of the Utility Model

The purpose is to drive the eccentric shaft to rotate while the input shaft drives the rotating unit to rotate, so that the eccentric shaft as a whole has the technical effect of revolution plus rotation. The rotational movement of the eccentric shaft drives the output shaft to rotate through the force transmission unit to achieve the purpose of driving a large-power device with a small-power device.

[0006] To solve the above technical problems, the technical solution provided by the utility model is: a new type of power output device, including an input shaft, an output shaft, and an eccentric shaft;

The fixed seat is fixedly arranged on one side of the outer circle of the transmission plate. A slide rail arranged in the radial direction of the transmission plate is provided on the fixed seat. A rotary bearing slidably matched with the slide rail is arranged in the slide rail. The rotary bearing is sleeved on the force transmission rod. One end of the force transmission rod is fixedly arranged on one side of the outer circle of the torsion transmission plate;

[0010] The input shaft and the output shaft are coaxially arranged, and the eccentric shaft is eccentrically arranged with respect to the input shaft and the output shaft.

[0011] Further, a driving gear is coaxially connected to the output end of the motor. A driven gear is coaxially arranged on the eccentric shaft. The driven gear is in meshing transmission cooperation with the driving gear. The driving gear and the driven gear are both arranged in the fixed frame.

[0031] One end of the input shaft 1 is fixedly connected with a rotating unit 100. The other side of the rotating unit 100 is connected with an eccentric shaft 3. A torsion transmission plate 4 is sleeved on the eccentric shaft 3. One side of the outer ring of the torsion transmission plate 4 is connected with a transmission plate 5 through a force transmission unit 200. The center of the transmission plate 5 is coaxially connected with the output shaft 2;

[0032] The rotating unit 100 includes a fixed frame 6 and a motor 7 arranged in the fixed frame 6. The output end of the motor 7 is in transmission connection with the eccentric shaft 3, and the eccentric shaft 3 is rotationally and cooperatively connected with the fixed frame 6;

[0033] The force transmission unit 200 includes a force transmission rod 8, a rotary bearing 9, a slide rail 10, and a fixed seat 11.

One end of the force transmission rod 8 is fixedly arranged on one side of the outer ring of the torsion transmission plate 4. While the force transmission unit revolves and rotates with the torsion transmission plate, force is input through the force transmission rod. Through the hinge transmission between the rotary bearing and the input end transmission rod and the rolling transmission between the rotary bearing and the slide rail, the force is transmitted to the transmission plate, achieving the technical effect of driving the output shaft to rotate.

[0034] The input shaft 1 and the output shaft 2 are coaxially arranged, and the eccentric shaft 3 is eccentrically arranged with respect to the input shaft 1 and the output shaft 2.

[0035] In a preferred embodiment of the present embodiment, a driving gear 701 is coaxially connected to the output end of the motor 7.

The driving gear 701 and the driven gear 702 are both arranged in the fixed frame 6.

[0036] During specific implementation, a reduction motor is used for the motor. When starting, it drives the driving gear to rotate. The driving gear drives the driven gear to rotate, and the driven gear drives the eccentric shaft to rotate, achieving the technical effect of driving the eccentric shaft to rotate itself. In this embodiment, the driving of the eccentric shaft by the motor is not limited to the gear transmission method, and other transmission methods can be adopted for connection, such as transmission sprockets, transmission belts, etc.

[0037] The eccentric shaft revolves with the rotating unit and rotates itself under the drive of the motor. The two-way input makes the rotational torque of the eccentric shaft greater.

[0038] In a preferred embodiment of the present embodiment, a torque output plate 12 is coaxially arranged at one end of the eccentric shaft 3 away from the rotating unit 100.

[0039] During specific implementation, the eccentric shaft rotates to drive the torque output plate to rotate, and the rotation of the torque output plate drives the torsion spring to twist. When the torsion spring accumulates driving force, it drives the torsion transmission plate to rotate, avoiding the vibration caused by the sudden force on the torsion transmission plate due to the sudden start of the motor, and achieving the effect of buffering and shock absorption.

[0040] A preferred implementation mode of this embodiment is that a slip ring 14 is sleeved on the input shaft 1.

A one-way clutch 15 is arranged on one side of the transfer plate 5, and the transfer plate 5 is connected to the output shaft 2 through the one-way clutch 15.

[0042] The setting of the one-way clutch enables the output shaft to rotate in only one direction, avoiding the risk of reverse rotation.

What is shown in the drawings is only one of the implementation modes of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative work without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
