[0045] See also Figure 5-9 The flow blocker 5 includes a baffle 501, a plurality of liquid holes 502 are provided in the middle of the baffle 501, and a cross-shaped blocking bar 503 is fixedly connected in the middle of the liquid holes 502, so that the viscous liquid can be blocked by the flow blocker. The linkage structure 6 includes a wedge block 601, and both ends of the wedge block 601 are fixedly connected to a limit hinge 602, and the limit hinge 602 is hinged with an interception plate 603, so that the linkage structure 6 can be adjusted according to the flow direction of the viscous liquid.

[0046] See also Figure 4-8 The middle of the housing 3 contains a viscous liquid, and the viscosity of the viscous liquid is between 6200-9800 mPa·s, so that the viscous liquid can reduce the motion energy of the stopper 8 through the blocking effect of the linkage structure 6 and the baffle 5. The limit plate 12 is fixedly connected to the inner wall of the housing 2, and the inner material of the housing 2 is hard plastic, so that the limit plate 12 can transmit the vibration energy of the vibration suppression structure to the housing 2, and the housing 2 is not easily damaged.

[0047] See also Figure 7-10 The stopper 8 seals the part of the shell 3 on the left side of the dividing strip 4, and the annular protrusion 10 limits the stopper 8, so that the viscous liquid is not easy to overflow from the shell 3, and the stopper 8 is not easy to fall off from the middle of the shell 3. The angle between the left and right sides of the wedge block 601 and the vertical line is 20°, and the width of the interception plate 603 is smaller than the distance between the upper side of the dividing strip 4 and the upper side of the middle of the shell 3, so that the wedge block 601 can block the interception plate 603, and the interception plate 603 is not easy to block the gap between the dividing strip 4 and the upper side of the middle of the shell 3. The rotation angle of the limit hinge 602 is 0°-70°, and the limit hinge 602 has a reset function, so that the limit hinge 602 can be rotated to a suitable angle, and the linkage structure 6 can be reset.

[0048] When the servo motor is working, the motor body 1 vibrates continuously with a small amplitude, and the vibration is transmitted to the stopper 8 through the connecting rod 9. The stopper 8 slides in the middle of the shell 3. When the stopper 8 moves upward, the viscous liquid inside the shell 3 is pushed upward by the stopper 8, and the viscous liquid drives the linkage structure 6 at the upper end of the partition bar 4 to move. At this time, the left interception plate 603 rotates along the left limit hinge 602, and the interception plate 603 is blocked by the wedge block 601 after rotating 70° clockwise. The interception plate 603 performs the first blocking effect on the viscous liquid flowing from the left side to the right side, and the blocker 5 performs the second blocking effect on the viscous liquid flowing from the upper side to the lower side. The linkage structure 6 at the lower end of the bar 4 moves. At this time, the right interception plate 603 rotates along the right limit hinge 602. The interception plate 603 rotates 70° clockwise and is blocked by the wedge block 601. The interception plate 603 performs a third blocking effect on the viscous liquid flowing from the right to the left. The viscous liquid is blocked, so that the energy of the upward movement of the stopper 8 is reduced. When the stopper 8 moves downward, the viscous liquid is also blocked by the above situation, so that the energy of the downward movement of the stopper 8 is reduced. Finally, the energy of the movement of the stopper 8 is reduced by the viscous liquid, so that the movement amplitude of the connecting rod 9 is reduced, thereby reducing the vibration amplitude of the motor body 1, thereby reducing the occurrence of noise. The vibration suppression structure can achieve the effect of suppressing the vibration of the motor body 1, so that the small vibration generated by the servo motor during operation is suppressed, and the noise generated by the servo motor due to vibration is reduced.

[0049] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
