Description

Technical Field

[0001] The invention relates to an optical rocker potentiometer device, and in particular to a simplified optical rocker potentiometer device and a modular packaging structure. Background Art

[0002] At present, the existing contact rocker potentiometer structure includes a housing, a rocker, a rocker mechanism and an adjustment potential module. The rocker outputs a steering action through the two shaft output ends of the rocker mechanism, and at the same time drives the conductive spring in the adjustment potential module in two directions to rotate, thereby changing the contact position of the conductive terminal on the conductive spring on the resistor, and then changing the output resistance value, thereby judging the swing direction of the rocker. For example, the invention patent with the Chinese patent announcement number CN 210073523 U, named "an improved rocker potentiometer structure", the invention patent with the Chinese patent announcement number CN 211858297 U, named "a low-wear rocker potentiometer", and the invention patent with the Chinese patent announcement number CN 210052601U, named "a rocker potentiometer structure with a switch", are all contact rocker potentiometer structures. Since the adjustment potential module of the contact rocker potentiometer adopts a contact structure, after a period of use, it is easy to have problems such as wear, breakage, and poor contact of accessories, thereby affecting the normal use and service life of the potentiometer. In order to overcome the above-mentioned problems, some non-contact optical rocker potentiometers have also appeared recently, such as the invention patent with the Chinese patent announcement number CN 219246467 U and the name "A non-contact optical rocker potentiometer", which discloses a non-contact optical rocker potentiometer, including a housing, a rocker and a rocker mechanism, wherein the rocker mechanism is installed in the housing and connected to one end of the rocker, and the other end of the rocker extends out of the housing, and the rocker mechanism is provided with at least two steering output ends, and a light blocking portion is provided on the steering output end, and light-emitting elements and photosensitive elements are respectively provided on both sides of the light blocking portion, and the light-emitting elements and photosensitive elements are connected to the PCB board... However, the structural design of the rocker mechanism and the light blocking portion is relatively complex, with many parts, cumbersome assembly, and its volume is large, which is not suitable for installation and use in a small space. Therefore, the development of a simple optical rocker potentiometer device and a modular packaging structure has become a problem to be solved by those skilled in the art. Summary of the invention

[0004] The above-mentioned object of the present invention is achieved through the following technical scheme: a simple optical rocker potentiometer device, including a PCB board and a rocker, a spring for supporting the rocker and resetting the rocker is provided between the PCB board and the rocker, the rocker includes a rod portion, and a spherical cover is connected to the lower end of the rod portion; two groups of light-emitting elements and photosensitive elements are provided on the PCB boards on the inner and outer sides of the lower edge of the spherical cover, the light paths of the two groups of light-emitting elements and the photosensitive elements are at an angle of 90 degrees, and the extension lines of the two light paths intersect and are perpendicular to the axis line of the rocker.

[0005] Furthermore, a spring lower fixing seat is provided on the PCB board, a spring upper fixing seat is provided on the top of the spherical cover, and the upper and lower ends of the spring are respectively fixedly connected to the spring upper fixing seat and the spring lower fixing seat.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] Example 1: Figures 1 to 4 As shown, a simple optical rocker potentiometer device includes a PCB board 1 and a rocker 2, wherein a spring 3 for supporting the rocker 2 and enabling the rocker 2 to reset is arranged between the PCB board 1 and the rocker 2, wherein the rocker 2 includes a rod portion 201, wherein the lower end of the rod portion 201 is connected to a spherical cover 202, wherein a spring lower fixing seat 101 is arranged on the PCB board 1, and a spring upper fixing seat 203 is arranged at the top of the spherical cover 202, wherein the upper and lower ends of the spring 3 are respectively fixedly connected to the spring upper fixing seat 203 and the spring lower fixing seat Seat 101, there is a gap 4 between the lower edge of the spherical cover 202 and the PCB board 1; in order to make the connection between the upper and lower ends of the spring 3 more stable, a protrusion T that can clamp the spring 3 can be provided on the spring upper fixing seat 203 and the spring lower fixing seat 101; two groups of light-emitting elements 5 and photosensitive elements 6 are provided on the PCB board 1 on the inner and outer sides of the lower edge of the spherical cover 202, and the light path angle of the two groups of light-emitting elements 5 and photosensitive elements 6 is 90 degrees, and the extension lines of the two light paths intersect and are perpendicular to the axis line of the rocker 2.

[0018] In order to prevent the lower edge of the spherical cover 202 from interfering with the PCB board 1 when the rocker 2 swings, a spherical cover avoidance opening 102 is provided on the PCB board 1 , and a PCB board avoidance opening 204 is provided on the spherical cover 202 .

[0019] In the initial state, part of the light (upper half) emitted by the light emitting element 5 is blocked by the lower edge of the spherical cover 202, and the other part of the light (lower half) is not blocked and is received by the photosensitive element 6, and the photosensitive element 6 generates a corresponding resistance value. When the rocker 2 is rocked by force, the position of the lower edge of the spherical cover 202 connected to its lower end changes, thereby changing the amount of light blocked by it, so that the light received by the two photosensitive elements 6 also changes, thereby generating a corresponding resistance value (the greater the amount of light, the smaller the resistance value of the photoresistor), and the photosensitive element 6 transmits the resistance signal to the single-chip microcomputer on the PCB board 1, and the single-chip microcomputer identifies the corresponding angle position of the rocker 2 according to the resistance value.

[0020] Example 2: Figure 5 , Figure 6As shown, a modular packaging structure of a simple optical joystick potentiometer device includes the simple optical joystick 2 device and a shell, the shell includes an upper shell 7 and a bottom cover 8, the upper shell 7 and the bottom cover 8 are connected by a snap-fit ​​structure or by screws, a first opening 701 is provided on the top of the upper shell 7, and the rod portion 201 of the joystick 2 and the upper part of the spherical cover 202 are exposed from the first opening 701; the PCB board 1 connecting cable 103 is led out from a second opening 702 set on one side of the upper shell 7.
