Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically to a novel servo-driven lifting system. Background Technology

[0002] Existing servo lifting technology uses a double crank linkage mechanism, which drives the lifting motion through a shaft. The force is uneven during the motion, resulting in greater wear on one side of the guide shaft. This can easily lead to uneven wear in the later stages, affecting the overall motion accuracy and resulting in a poor overall lifespan. Power transmission is achieved through a single drive shaft, which results in low power transmission efficiency and high losses.

However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0016] Combination Figures 1 to 3 As shown, a novel servo-driven lifting system includes a lifting mounting base plate 100. The lifting mounting base plate 100 is provided with a transmission mechanism and a scissor lift assembly for realizing the lifting action. The transmission mechanism includes a servo motor 111 and a lead screw assembly driven by the servo motor 111.

[0017] Furthermore, in another embodiment, a guide shaft connecting strip 120 and a rocker arm support 130 are provided above the push mounting base plate 100, and a main push plate 121 is fixedly installed above the guide shaft connecting strip 120.

[0018] Furthermore, in another embodiment, the scissor lift assembly includes fork A131 and fork B132. Fork B132 is symmetrically installed on both sides of the guide shaft connecting strip 120.
