[0029] Example 1: Please refer to Figure 1-7 , the present invention provides a technical solution:

[0030] An automatic clutch gear reduction motor includes a motor body 1 for driving, a reduction gear structure 2 for reducing speed, and an automatic clutch structure 3 for connecting the motor body 1 and the reduction gear structure 2. A motor base 4 for supporting is installed at the bottom end of the motor body 1, a reduction gear structure base 5 for supporting is installed at the bottom end of the reduction gear structure 2, and a bottom plate 6 is provided at the bottom end of the motor body 1.

[0031] The automatic clutch structure 3 includes a hydraulic oil pump oil structure 7, a hydraulic oil transmission structure 8 and an automatic clutch structure shell 15. The output shaft of the motor body 1 rotates through the hydraulic oil pump structure 7 to pump the oil into the inner side of the first connecting pipe 10. The first connecting pipe 10 pushes the oil into the second connecting pipe 11. The other end of the second connecting pipe 11 is connected to the hydraulic oil transmission structure 8 and drives the transmission shaft 28. A third connecting pipe 12 for controlling the reflux of the oil is installed on one side of the hydraulic oil transmission structure 8, and the other end of the third connecting pipe 12 is installed on one side of the oil storage tank 13 for storing the oil. A fourth connecting pipe 14 for oil transportation is connected between the oil storage tank 13 and the hydraulic oil pump structure 7. This arrangement, through the hydraulic oil pump oil structure and the hydraulic oil transmission structure, makes the device as a whole constitute a set of structures that can not only increase the output torque but also automatically control the clutch, thereby ensuring the life of the equipment and better output power.

[0032] The motor body 1 is mounted on one side of the base plate 6 through the motor seat 4, the reduction gear structure 2 is mounted on one side of the base plate 6 through the reduction structure seat 5, and the automatic clutch structure 3 is mounted on one side of the base plate 6, and the motor body 1, the reduction gear structure 2 and the automatic clutch structure 3 are all located on the same side of the base plate 6. This arrangement can better install the motor body 1, the reduction gear structure 2 and the automatic clutch structure 3 to ensure their stable use; the reduction gear structure 2 includes a gear box 21 for installing the reduction gear and an output shaft 22 for outputting power. A first large gear 23 arranged coaxially is mounted on the outer side of the output shaft 22, and one side of the first large gear 23 is meshed with a first Small gear 24, a horizontal shaft 25 is installed on the inner side of the first small gear 24, and a second large gear 26 is installed on the other end of the horizontal shaft 25. A second small gear 27 is meshed with the other side of the second large gear 26, and a transmission shaft 28 is installed on the inner side of the second small gear 27. This and the lion can effectively reduce the speed of the output shaft 22, thereby achieving a better deceleration effect; one end of the first connecting pipe 10 is installed on the top side of the hydraulic oil pump oil structure 7, and one end of the fourth connecting pipe 14 is installed on the other side of the top of the hydraulic oil pump oil structure 7; one end of the second connecting pipe 11 is installed on the bottom side of the hydraulic oil transmission structure 8, and one end of the third connecting pipe 12 is installed in the hydraulic oil transmission structure On the other side of the bottom end of 8, this arrangement ensures that the hydraulic oil pump oil structure 7 can pump out the oil well, thereby driving the hydraulic oil transmission structure 8 to work; the hydraulic oil pump oil structure 7 includes a hydraulic oil pump oil shell 71 and an eccentric wheel 72, one end of the hydraulic oil pump oil shell 71 is in contact with the automatic clutch structure shell 15, and a non-concentric eccentric wheel 72 is installed on the inner side of the hydraulic oil pump oil shell 71, and the outer side of the eccentric wheel 72 is always in contact with the inner side wall of the hydraulic oil pump oil shell 71, and a slide groove 73 is provided on the inner side of the slide groove 73, and two sealing blocks 74 arranged on the left and right are slidably provided on the inner side of the slide groove 73, and an extrusion spring 75 is installed between the two sealing blocks 74. The side of 74 that fits with the hydraulic oil pump oil housing 71 is rounded. This arrangement can simply and stably pump out the oil by the rotation of the motor, thereby facilitating the subsequent promotion of the hydraulic oil transmission structure 8 to work; the hydraulic oil transmission structure 8 includes a hydraulic oil transmission housing 81 and a rotating blade 82. One side of the hydraulic oil transmission housing 81 fits with the hydraulic oil pump oil housing 71. A rotating ring 83 for driving the rotating blade to rotate is rotated on the inner side of the hydraulic oil transmission housing 81, and the rotating ring 83 is mounted on one end of the transmission shaft 28. The outer side of the rotating ring 83 is mounted with a rotating blade 82. This arrangement can better drive the transmission shaft 28 to rotate through the oil, thereby achieving the effect of outputting power;The number of rotating blades 82 is multiple, and the rotating blades 82 are evenly distributed on the outside of the rotating ring 83. The distance between the ends of adjacent rotating blades 82 close to the hydraulic oil transmission housing 81 is 2-3 times the distance between the second connecting pipe 11 and the third connecting pipe 12 on the hydraulic oil transmission housing 81, and a through hole 84 is opened on the rotating blade 82. This setting has a good buffering effect, thereby reducing the load on the motor body 1 and ensuring the service life; the automatic clutch structure 3 also includes an auxiliary control structure 9, which includes a connection box 91 for connecting the first connecting pipe 10 and the second connecting pipe 11. The inner side of the connection box 91 is installed with a manual control mechanism. A partition plate 92 is used, and a manual control structure 93 is mounted on one side of the partition plate 92. The manual control structure 93 includes a control plate 931 for pushing hydraulic oil. A push rod 932 is mounted on one side of the control plate 931 for easy control. A push plate 933 is mounted on the other end of the push rod 932. A return spring 934 is also mounted on the outside of the push rod 932 to drive the control plate 931 back to its original position. The return spring 934 is located inside the connection box 91. This arrangement allows the output shaft to be manually controlled to rotate before use, effectively increasing the starting torque and thus effectively reducing the friction of the motor body, which helps to extend the service life of the motor body.

[0033] Working process: First, when the motor body 1 is started, the motor body 1 drives the eccentric wheel 72 to rotate in the hydraulic oil pump oil shell 71. Due to the setting of the extrusion spring 75, the sealing block 74 always fits the hydraulic oil pump oil shell 71, thereby continuously pumping the oil from the oil storage tank 13 into the hydraulic oil transmission structure 8. This setting can gradually convert power into hydraulic form, thereby effectively increasing the output torque and ensuring the output of power;

[0034] When the oil enters the hydraulic oil transmission housing 81, the oil will drive the rotating blades 93 and the rotating ring 92 to rotate, thereby driving the output shaft 28 to rotate, achieving the effect of outputting power. When the external resistance is large, the oil will flow from the inside of the through hole 84, thereby achieving the effect of automatic clutching. Moreover, this connection method not only reduces wear and tear, but also does not cause problems due to high temperature. Finally, the oil enters the oil storage tank 13 through the fourth connecting pipe 14, completing the cycle.

[0035] The power obtained by the transmission shaft 28 will be decelerated through the second small gear 27, the second large gear 26, the first small gear 24 and the first large gear 23, and finally output through the output shaft 22. When the friction force of the device is large at the beginning, the push plate 933 can be pressed, and then the push rod 932 and the control plate 931 can be used to assist in pumping out the oil, thereby effectively increasing the torque and ensuring the smooth operation of the device.

The above examples are only used to help understand the method of the present invention and its core ideas. The above is only a preferred implementation method of the present invention.
