Description

Technical Field

[0001] The invention relates to an optical rocker potentiometer device, in particular to an optical rocker potentiometer module. Background Art

[0002] At present, the existing contact rocker potentiometer structure includes a housing, a rocker, a rocker mechanism and an adjustable 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 adjustable 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", the invention patent with the Chinese patent announcement number CN 210052601U, named "a rocker potentiometer structure with a switch", and the invention patent with the Chinese patent announcement number CN 209000660 U, named "a thin rocker potentiometer", 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, poor contact, etc. of the accessories, thereby affecting the normal use and service life of the potentiometer. Therefore, the development of an optical rocker potentiometer module has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0003] The present invention is to solve the above-mentioned shortcomings and provides an optical rocker potentiometer module.

[0004] The above-mentioned purpose of the present invention is achieved through the following technical scheme: an optical rocker potentiometer module, including a PCB board and a rocker, the PCB board is provided with two groups of light-emitting elements and photosensitive elements, the light paths of the two groups of light-emitting elements and photosensitive elements intersect and are perpendicular, the rocker includes a rod portion, and the lower end of the rod portion is connected to a cross-shaped gradient shading component.

[0005] Furthermore, the PCB board is provided with an avoidance opening to prevent the cross-shaped gradient shading component from causing motion interference with the PCB board when the rocker is swung.

[0006] Furthermore, the cross-shaped gradual light-shielding component comprises two vertical panels perpendicular to each other, and the vertical panels are provided with transverse gradual light-transmitting openings.

[0007] Furthermore, the cross-shaped gradient shading component includes two mutually perpendicular transverse width-gradient shading plates.

[0008] Furthermore, the lateral width-gradient shading plate is in a triangular shape.

[0009] The advantages of the present invention compared with the prior art are: the present invention not only utilizes optical principles and adopts a non-contact method, but also determines the swing direction of the rocker through the cooperation of light-emitting elements and photosensitive elements, thereby avoiding the problems of accessory wear, breakage, poor contact, etc. that are prone to occur in contact-type potential adjustment modules, thereby enhancing the stability of the potential device and extending the service life of the potential device.

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

[0017] Example 1: Figure 1As shown, an optical rocker potentiometer module comprises a PCB board 1 and a rocker 2, wherein the PCB board 1 is provided with two groups of light emitting elements 3 and photosensitive elements 4, the light paths of the two groups of light emitting elements 3 and photosensitive elements 4 intersect and are perpendicular, the rocker 2 comprises a rod portion 201, the lower end of the rod portion 201 is connected to a cross-shaped gradual shading component 202, the cross-shaped gradual shading component 202 is two mutually perpendicular vertical panels 202-1, the vertical panels 202-1 are provided with a transverse gradual light transmission opening 202-2, the transverse gradual light transmission opening 202-2 is triangular, and the transverse gradual light transmission opening 202-2 gradually changes from a narrow opening at one end to a wide opening at the other end; the PCB board 1 is provided with an avoidance opening 5 to prevent the cross-shaped gradual shading component 202 from generating motion interference with the PCB board 1 when the rocker 2 is swung. Working principle: In the initial state, the light emitted by the two light-emitting elements 3 passes through the transverse gradient light-transmitting port 202-2 of the cross-shaped gradient light-shielding component 202 to reach the photosensitive element 4, and is received by the photosensitive element 4, which generates a corresponding resistance value. When the rocker 2 is forced to swing, the position of the cross-shaped gradient light-shielding component 202 is offset, causing the amount of light reaching the photosensitive element 4 through the transverse gradient light-transmitting port 202-2 to change (increase or decrease), so that the light received by the two photosensitive elements 4 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 4 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.

[0018] Example 2: Figure 2As shown, an optical rocker potentiometer module includes a PCB board 1 and a rocker 2, wherein the PCB board 1 is provided with two groups of light emitting elements 3 and photosensitive elements 4, the light paths of the two groups of light emitting elements 3 and photosensitive elements 4 intersect and are perpendicular, the rocker 2 includes a rod portion 201, the lower end of the rod portion 201 is connected to a cross-shaped gradual shading component 202, the cross-shaped gradual shading component 202 is two mutually perpendicular transverse width and narrow gradual shading plates 202-3, and the transverse width and narrow gradual shading plates 202-3 are triangular (in other embodiments, they can also be other transverse gradual shapes, that is, a shape with one end wide and the other end narrow); an avoidance opening 5 is provided on the PCB board 1 to prevent the cross-shaped gradual shading component 202 from causing motion interference with the PCB board 1 when the rocker 2 is swung. Working principle: In the initial state, the light emitted by the two light-emitting elements 3 is received by the photosensitive element 4, and the photosensitive element 4 generates a corresponding resistance value. Part of the light is blocked by the horizontal width and narrow gradient shading plate 202-3 of the cross-shaped gradient shading component 202, and cannot reach the photosensitive element 4. When the rocker 2 is forced to swing, the position of the cross-shaped gradient shading component 202 is offset, so that the horizontal width and narrow gradient shading plate 202-3 is offset, resulting in a change in the amount of light blocked (increasing or decreasing), so that the light received by the two photosensitive elements 4 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 4 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.
