Description

Technical Field

[0001] This utility model relates to the field of encoder technology, and in particular to a push-type encoder. Background Technology

[0002] Traditional rotary encoders have the following main technical defects: structural complexity, with most products adopting a separate design for the rotary encoder and the push switch, resulting in a large number of parts and a large axial dimension; in the positioning structure of traditional encoders, long-term friction between the plastic claw and the metal cam can lead to positioning ambiguity; in addition, the separate design of the push switch and the rotary encoder has an operating axis deviation, resulting in significant differences in the feel of pressing at different angles. Summary of the Invention

[0003] This utility model addresses the problems of existing technologies by providing a push-to-response encoder with a novel structure. It generates a clear positioning tactile sensation. An elastic element sleeved on the shaft core connects the positioning element and the shaft sleeve. During rotation, it stores elastic potential energy, providing rotational resistance and automatic reset function, and also generates force on the positioning element, resulting in better positioning point effect when the positioning convex and positioning groove cooperate. It integrates dual functions, realizing rotation encoding and push-to-response switch functions on the same shaft core, simplifying the complexity of the separate structure in traditional designs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a push-button encoder, which includes a shaft core and a bushing, a positioning plate, an encoder body, and a push-button switch body connected in sequence. The shaft core is movably inserted through the bushing, the positioning plate, and the encoder body. A movable arm is sleeved on the outer periphery of the shaft core and is movably disposed on the encoder body. The movable arm is located between the encoder body and the positioning plate. A positioning element is sleeved on the outer periphery of the shaft core and is movably disposed on the positioning plate. A positioning protrusion is provided on the lower end face of the positioning element. A plurality of positioning grooves that cooperate and abut with the positioning protrusion are provided at equal intervals on the positioning plate. An elastic element is also movably sleeved on the outer periphery of the shaft core. The elastic element is located between the positioning element and the bushing, and its two ends are respectively connected to the positioning element and the bushing.

[0006] The elastic element is a spring.

[0007] The bushing has a through groove in the middle, the shaft core passes through the through groove, and a waterproof ring is provided at one end of the outer side of the through groove.

[0008] The push-button switch body is provided with a dome switch, and the lower end of the shaft core abuts against the dome switch.

[0009] An isolation plate is provided between the push-button switch body and the encoding body.

[0010] The positioning protrusion is provided in two parts, and the two positioning protrusions are respectively arranged on both sides of the lower end face of the positioning member.

[0011] The two positioning protrusions are symmetrically arranged about the center of the positioning member.

[0012] The positioning element is made of stainless steel powder.

[0013] The beneficial effects of this utility model are:

[0014] This utility model features a novel structure. The push-to-start encoder achieves precise indexing and positioning through the meshing of a positioning protrusion and a positioning groove. The positioning protrusion at the lower end of the positioning component mechanically meshes with multiple equally spaced positioning grooves on the positioning plate. When the shaft rotates, the positioning protrusion switches between different positioning grooves, generating a clear positioning tactile sensation. Furthermore, an elastic element sleeved on the shaft connects the positioning component and the bushing, storing elastic potential energy during rotation, providing rotational resistance and automatic reset function, and generating force on the positioning component, resulting in better positioning point performance under the engagement of the positioning protrusion and positioning groove. The moving arm (which can be a brush) serves as an intermediate transmission element, transmitting the rotational motion of the shaft to the encoder body while isolating the influence of axial movement on encoding accuracy. Simultaneously, this embodiment integrates a push-to-start function design, with the lower end of the shaft directly contacting the dome switch body, achieving direct pressure transmission without intermediate transmission, reducing energy loss and component wear. This utility model integrates dual functions, simultaneously realizing rotational encoding and push-to-start functions on the same shaft, simplifying the complexity of the separate structure in traditional designs.

The positioning protrusion 8 at the lower end of the positioning member 7 and the multiple positioning grooves 9 evenly spaced on the positioning plate 3 form a mechanical mesh. When the shaft core 1 rotates, the positioning protrusion 8 switches between different positioning grooves 9, producing a clear positioning tactile sensation. Furthermore, the elastic member 10 sleeved on the shaft core 1 connects the positioning member 7 and the bushing 2. During rotation, it stores elastic potential energy, provides rotational resistance and automatic reset function, and generates force on the positioning member 7, so that the positioning protrusion 8 is positioned.

A waterproof ring 12 is provided at one outer end of the through groove 11. Specifically, the waterproof ring 12 serves a waterproofing function.

[0023] In this embodiment, an isolation plate 14 is provided between the push-button switch body 5 and the encoding body 4. Specifically, the isolation plate 14 serves to provide mechanical and electrical isolation, preventing interference between the push-button switch body 5 and the encoding body 4, thus ensuring structural reliability.
