Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a mechanical encoder, especially to a mechanical encoder which does not need electronic sensing module or other passive electronic elements for signal transmission, can reduce the assembly cost of the utility model encoder, and the mechanical structure can reduce the volume for use, so that the electronic equipment with smaller volume can be batched, the cost is reduced, and more equipment can be batched. BACKGROUND
[0002] The existing rotary encoder can be mainly divided into optical encoder, magnetic sensing type encoder and mechanical contact switch encoder according to different sensing methods. Among them, the optical type and the magnetic sensing type encoder adopt electronic elements combined with sensing circuit to output signals, which can provide high resolution and diversified data feedback, but the structure is complex, the manufacturing cost is high, and it depends on the microcontroller combined with operation logic processing. In specific application occasions (such as small equipment, low-cost goods or no circuit system), the design is redundant and the cost is not in line with the benefit.
[0003] And the conventional mechanical rotary encoder has the advantages of low power consumption and simple structure, but it only provides a single trigger structure, relies on a single spring under the rotating piece and a fixed contact to generate a paragraph type conduction signal, and the overall operation stability and touch performance are limited. Part of the mechanism cannot accurately control the pressing position, which is easy to cause paragraph feeling fuzzy and trigger error increase due to assembly error or use wear, in addition, the common design lacks modular separation design, which makes maintenance or customization difficult, and cannot meet the needs of small batch and diversified applications.
[0004] Furthermore, the conventional structure does not generally configure compensation elements such as intermediate conductive gaskets, so that the contact compression is uneven, the contact resistance fluctuates and other problems are common after long-term use, which leads to unstable signal or reduced product life. Therefore, how to improve the contact stability, paragraph clarity and modular elastic design capability under the premise of maintaining the simple mechanical structure and low cost is the key to be researched and improved by those engaged in this industry.
