Jack and stroke measurement method thereof

Abstract

The embodiment of the invention discloses a jack and a stroke measurement method thereof, relates to the technical field of machinery, and can perform high-reliability stroke measurement under the condition of ensuring the compact structure of the jack. The jack comprises a cylinder body and a piston matched with the cylinder body, and the cylinder body and the piston are sealed to form a piston cavity; a pull rope coding device is fixed on the inner wall of the piston cavity; the pull rope encoding device is connected with the inner wall of the piston cavity in a sealed mode through a sealingmechanism and divides the piston cavity into a first cavity and a second cavity, the first cavity is close to the piston and is sealed by the piston, and the second cavity is far away from the pistonand is isolated from the piston; a pull rope mechanism of the pull rope coding device is located in the first cavity, and a data processing component of the pull rope coding device is located in thesecond cavity; the wire outlet end of the pull rope mechanism is fixedly connected with the piston; and the data processing part is connected with the pull rope mechanism.

AI Technical Summary

Benefits of technology

This technology allows for accurate measurements without damaging any part outside the jack itself while still ensuring proper functioning during use. It uses two separate chambers with one sealing off from another to encodes signals like pulse numbers (pitch) onto wires instead of magnet rings. By placing sensors within these chambounds, there will be no risk of accidental contact between them due to environmental factors such as dirtiness or shock waves. Additionally, when designing small jacks, reducing their overall dimensions helps maintain functionality even further. Overall, this new technique simplifies manufacture processes and reduces costs compared to existing techniques used today.

Problems solved by technology

This patented technical problem addressed in the present patents relates to improving the performance and durability of electronic devices like lamps during use without taking up too much room inside them due to their weight and size constraints. Current solutions involve adding extra parts (such as wires) outside the housing, making the overall design more bulky than desired.
