Description

Technical Field

[0001] The utility model provides a micro ultra-thin mini incremental belt key encoder, belonging to the technical field of key encoders. Background Art

[0002] A key encoder is a device used to convert key operations into digital signals. It plays an important role in many electronic devices and computer systems. The working principle of a key encoder usually includes scanning a key matrix, identifying the pressed key, and converting the state of the key into a digital signal for output. Different types of encoders can be selected according to application requirements. For example, a key encoder inside a single-chip microcomputer or a dedicated key encoding chip.

[0003] Based on the above, the inventor found that:

[0004] Traditional encoders do not have an anti-detachment function, are complex in structure, unstable, not easy to operate, are prone to misalignment during installation, and cannot improve the installation accuracy.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure, and a micro ultra-thin mini incremental belt key encoder is proposed to solve the above existing problems. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is that traditional encoders do not have an anti-detachment function, the structure is unstable and the installation accuracy cannot be improved.

[0007] To solve the above problems, the technical solution proposed by the utility model is: a micro ultra-thin mini incremental belt key encoder, including a signal body and a housing connected to the signal body. A positioning piece is arranged between the signal body and the housing, and a wave disk and a brush are sequentially arranged inside the signal body at the lower end of the positioning piece. A handle is arranged on one side of the housing, and the lower end of the handle passes through the housing and the positioning piece and is placed inside the wave disk.

[0008] Further, the outer diameter of the wave disk is adapted to the inner diameter of the signal body, and the lower end of the wave disk is placed on the cylindrical protrusion at the bottom of the signal body.

[0009] Further, the brush is provided with three through holes I and a through hole II in the middle. The lower end of the wave disk is placed inside the through hole II, and a limiting column corresponding to the through hole I is fixedly connected to the circumferential side of the wave disk. The limiting column is placed inside the through hole I, and the brush is fixedly connected to the wave disk.

[0010] Further, the positioning piece is provided with a through hole III adapted to the protrusion of the signal body, and the protrusion is placed inside the through hole III.

[0011] Further, the bottom of the handle is in a hemispherical structure, and the middle section is in a square structure. A limiting groove adapted to the square structure is provided on the undulating disc, and the square structure is placed in the limiting groove and is adapted to its inner diameter.

[0012] Further, anti-detachment holes are provided on the outer shell, and limiting blocks adapted to the anti-detachment holes are provided on the signal body. The limiting blocks are placed in the anti-detachment holes. A notch is provided at the bottom of the signal body, and a partial pressing piece at the lower end of the outer shell is bent into the notch.

[0013] Due to the adoption of the above technical solutions, the beneficial effects of the present utility model, a micro-thin mini incremental encoder with a button, are as follows:

[0014] 1. By providing a positioning piece between the signal body and the outer shell, and arranging an undulating disc and a brush at the lower end of the positioning piece, the stability and accuracy of the internal components of the encoder can be effectively maintained. The cooperation between the positioning piece and the undulating disc ensures the precise operation of the encoder.

[0015] 2. Through the cooperation of the anti-detachment holes on the outer shell and the limiting blocks on the signal body, and the arrangement of the limiting posts, the accidental detachment of the undulating disc is prevented, and the stability of the outer shell and the signal body is increased.

[0025] Please refer to Figures 1-4 As shown in the figure: The present invention provides a micro ultra-thin mini incremental encoder with a button: It includes a signal body 1 and a housing 2 connected to the signal body 1. A positioning piece 3 is arranged between the signal body 1 and the housing 2, and a fluctuation disk 4 and a brush 5 are sequentially arranged at the lower end of the positioning piece 3 and inside the signal body 1. The outer diameter of the fluctuation disk 4 is adapted to the inner diameter of the signal body 1, and the lower end of the fluctuation disk 4 is placed on the cylindrical protrusion 12 at the bottom of the signal body 1. A handle 6 is arranged on one side of the housing 2, and the lower end of the handle 6 passes through the housing 2 and the positioning piece 3 and is placed inside the fluctuation disk 4. The bottom of the handle 6 is in a hemispherical structure, and the middle section is in a square structure 14. A limit groove 11 adapted to the square structure 14 is arranged on the fluctuation disk 4, and the square structure 14 is placed in the limit groove 11 and is adapted to its inner diameter.

[0026] Three first through holes 7 are arranged on the brush 5, and a second through hole 8 is arranged in the middle. The lower end of the fluctuation disk 4 is placed in the second through hole 8, and a limit post 9 corresponding to the first through hole 7 is fixedly connected to the periphery of the fluctuation disk 4. The limit post 9 is placed in the first through hole 7, and the brush 5 is fixedly connected to the fluctuation disk 4.

[0027] A third through hole 10 adapted to the protrusion 13 of the signal body 1 is arranged on the positioning piece 3, and the protrusion 13 is placed in the third through hole 10.

[0028] The housing 2 is provided with anti-detachment holes 15, and the signal body 1 is provided with limit blocks 16 adapted to the anti-detachment holes 15. The limit blocks 16 are placed in the anti-detachment holes 15.

[0029] The principle of a micro ultra-thin mini incremental encoder with buttons of the present utility model is as follows:

[0030] The present utility model is also provided with a prior art dome switch. The dome switch is installed at the middle position of the signal body. The brush is aligned with the limit post of the wavy disk and installed. The wavy disk and the brush are fixedly connected by a riveting process (prior art). The wavy disk is placed on the cylindrical protrusion at the bottom of the signal body, as Figure 4 shown. The positioning piece is aligned with the protrusion of the signal body and installed.

After the housing is aligned with the signal body and installed, the limit block just gets stuck in the anti-detachment hole. The square structure of the handle is placed in the limit groove. Then, the position of the pressing piece is bent and stuck at the notch. When the handle is pressed, the hemispherical structure at the lower end of the handle contacts the dome switch to achieve the pressing function.
