Description

[0001] The present utility model relates to the technical field of mechanical transmission, specifically to a new type of drive output device.

[0002] The drive output device, also known as the power receiver, is a device that transmits the power of the motor or electric motor to the outside. It typically consists of gears, shafts, housings, etc. The drive output device is divided into single-speed, double-speed, and three-speed according to the speed of its output power; according to the method of operation, it is divided into manual, pneumatic, electric, and fluid.

[0003] For existing drive output devices, the output shaft is often directly connected to the input shaft. The input shaft can also be connected to multiple output shafts through a gear. By inputting the drive force to the input shaft, multiple output shafts are simultaneously driven to output the drive force. However, regardless of the type of drive output device, low-power devices are driven by a low-power drive device, while high-power devices are driven by a high-power drive device. Currently, high-power devices cannot be driven by a low-power drive device.

[0004] In view of the technical problem described above, the applicant therefore researches and designs, in combination with the structure of existing output drive devices, a drive output device in which a high-performance system can be driven by means of a low-power drive device.

[0005] The technical problem to be solved by the present utility model is to eliminate the deficiencies of the above-mentioned technology, to provide a new type of drive output device which aims to drive the rotation of the eccentric shaft by the electric motor, while at the same time the rotation of the rotary unit is driven by the input shaft, so that the technical effect of the revolution and rotation of the eccentric shaft is achieved as a whole, wherein the rotary movement of the eccentric shaft through the power transmission unit drives the output shaft to rotate, in order to enable the goal of driving high-performance equipment by means of small power devices.

[0006] In order to solve the above-mentioned technical problem, the present utility model provides the technical solution: a new type of drive output device comprising an input shaft, an output shaft, an eccentric shaft; the input shaft is fixedly connected at one end to a rotary unit, which is connected at another side to the eccentric shaft, a rotary force transmission plate is mounted on the eccentric shaft, one side of an outer circumference of the rotary force transmission plate is connected via a power transmission unit to a transmission plate, which is centrally connected coaxially to the output shaft; the rotary unit comprises a mounting bracket, an electric motor provided within the mounting bracket, the output end of which is in driving connection with the eccentric shaft, the eccentric shaft is in rotating connection with the mounting bracket; the power transmission unit comprises a power transmission rod, a rotary bearing, a rail, a mounting seat fixedly provided on the side of the outer circumference of the transmission plate, on the mounting seat a rail is provided in the radial direction of the transmission plate, inside the rail there is provided a rotary bearing slidably coordinating with the latter, which is mounted on the power transmission rod, the end of which is fixedly provided on one side of the outer circumference of the rotary force transmission plate; the input shaft and the output shaft are provided coaxially, the eccentric shaft is provided eccentrically with the input shaft and the output shaft.

[0007] Furthermore, an output end of the electric motor is coaxially connected with a drive gear, a driven gear is coaxially provided on the eccentric shaft, the drive gear and the driven gear are in meshing and transmission coordination, the drive gear and the driven gear are provided in the fixing bracket.

[0008] Furthermore, a torque output plate is provided coaxially at an end of the eccentric shaft facing away from the rotating unit, and a torsion spring is provided between the torque output plate and the torque transmission plate, which is mounted on the eccentric shaft.

[0009] Furthermore, a recess I is provided on one side in the center of the torque output plate, a recess II is provided on one side in the center of the torque transmission plate, the torsion spring is arranged with one end in the recess I and connected to the torque output plate, the torsion spring is arranged with another end in the recess II and connected to the torque transmission plate.

[0010] Furthermore, a conducting ring is attached to the input shaft, which is contacted and electrically connected to the electric motor; the conducting ring is connected to an external power supply via a wire.

[0011] Compared with the prior art, the advantage of the present utility model is: 1) The invention is novel and structurally simple, the rotary unit is driven to rotate by the input power through the input shaft, the electric motor provided on the rotary unit itself drives the eccentric shaft to rotate, the rotational movement of the eccentric shaft drives the output shaft to rotate through the power transmission unit, so that the effect of two-way input by rotation and revolution and one-way output is achieved; with the revolution, the rotation occurs slowly at the same time, the speed of the output shaft is slightly higher than the speed of the input shaft, the output and input speeds are almost synchronous. 2) Using the principle of force shift, the force shifts to the eccentric shaft, the force is obtained by introducing rotation; at the same time, additional torque must be input to the torque transmission plate, the additional torque is obtained by rotation, and a large torque can be output through the two-way input by rotation and revolution.

[0012] By driving the eccentric shaft to rotate via the dual input drive of the input shaft and the electric motor, the present utility model achieves the technical effect of driving the high-performance system with low-power drive. The design is intelligent and novel. At the same time, the technical effect of shock absorption or buffering is achieved by means of the torque spring between the torque output plate and the torque transmission plate, which is practical.

For those skilled in the art, the specific meaning of the above terms in the present utility model can be understood depending on the circumstances. Example 1:

[0019] Combined with Fig.1-4, a new type of drive output device comprising an input shaft 1, an output shaft 2, an eccentric shaft 3; the input shaft 1 is fixedly connected at one end to a rotary unit 100, which is connected at another side to the eccentric shaft 3, a rotary force transmission plate 4 is mounted on the eccentric shaft 3, one side of an outer circumference of the rotary force transmission plate 4 is connected via a power transmission unit 200 to a transmission plate 5, which is centrally connected coaxially to the output shaft 2; the rotary unit 100 comprises a mounting bracket 6, an electric motor 7 provided within the mounting bracket 6, the output end of which is in driving connection with the eccentric shaft 3, the eccentric shaft 3 is in rotary connection with the mounting bracket 6; The power transmission unit 200 includes a power transmission rod 8, a rotary bearing 9, a rail 10, and a mounting seat 11 fixedly provided on the outer periphery side of the transmission plate 5.

The power transmission unit rotates and rotates with the rotary power transmission plate. At the same time, the power is introduced through the power transmission rod. Through the hinged transmission of the rotary bearing and the input transmission rod, and the rolling transmission of the rotary bearings and rails, the power is transmitted to the transmission plate, enabling the technical effect of driving the output shaft to rotate.

[0020] The input shaft 1 and the output shaft 2 are provided coaxially, the eccentric shaft 3 is provided eccentrically with the input shaft 1 and the output shaft 2.

[0021] An advantageous embodiment of the embodiment is that an output end of the electric motor 7 is coaxially connected to a drive gear 701, a driven gear 702 is coaxially provided on the eccentric shaft 3, the drive gear 701 and the driven gear 702 are in engagement and transmission coordination, the drive gear 701 and the driven gear 702 are provided in the mounting bracket.

[0022] In the specific embodiment, a reduction motor is used for the electric motor to start and drive the drive gear to rotate. The drive gear drives the driven gear, and the driven gear drives the eccentric shaft to rotate, achieving the technical effect of the eccentric shaft rotation.
