Description

Technical Field

[0001] The present invention relates to an optical joystick, and in particular to an optical joystick module and a packaging structure thereof. 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 utility model patent with the Chinese patent announcement number CN 210073523 U, named "an improved rocker potentiometer structure", the utility model patent with the Chinese patent announcement number CN 211858297 U, named "a low-wear rocker potentiometer", the utility model patent with the Chinese patent announcement number CN 210052701 U, named "a rocker potentiometer structure with a switch", and the utility model patent with the Chinese patent announcement number CN 209000670U, named "a thin rocker potentiometer", are all contact rocker potentiometer structures.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0022] Example 1: Figure 1 As shown, an optical joystick module includes a PCB board 1 and a joystick 2, a reflector 3 extending from the lower part of the joystick 2, the reflector 3 is plate-shaped, and both the front and back sides are reflective surfaces, and an infrared transmitting and receiving integrated tube 4 is provided on the opposite side of each reflective surface, that is, two infrared transmitting and receiving integrated tubes 4 are respectively arranged on the front side and the back side of the reflector 3, and the two infrared transmitting and receiving integrated tubes 4 are staggered and distributed one on the left and the other on the right, and at the same time, the transmitting and receiving surfaces of the infrared transmitting and receiving integrated tube 4 face the reflective surface corresponding to it, the infrared transmitting and receiving integrated tube 4 is connected to the PCB board 1, and the bottom end height of the reflector 3 is located in the middle of the transmitting and receiving surface of the infrared transmitting and receiving integrated tube 4. Among them, "the two infrared transmitting and receiving integrated tubes 4 are staggered and distributed on the left and right" and "the bottom end height of the reflector 3 is located in the middle of the transmitting and receiving surface of the infrared transmitting and receiving integrated tube 4", so that a part of the emitted light of the infrared transmitting and receiving integrated tube 4 avoids the infrared light reflecting surface in the initial state, and then the joystick 2 reflects different amounts of light when it swings to different angles, so that the infrared transmitting and receiving integrated tube 4 can receive different amounts of light.

[0023] Working principle: In the initial state, part of the light emitted by the light-emitting elements of the two infrared transmitting and receiving integrated tubes 4 is irradiated onto the reflective surface, and the other part escapes from the bottom of the reflective surface. Under the reflection effect of the reflective surface, the light is irradiated onto the reflective surface and received by the photosensitive elements of the infrared transmitting and receiving integrated tubes 4. When the joystick 2 is shaken in a certain direction, the effective reflective area of ​​the reflective surface will increase or decrease accordingly (the effective reflective area formed by swinging to different angles is different), which causes the amount of light received by the photosensitive elements of the two infrared transmitting and receiving integrated tubes 4 to change, thereby generating a corresponding resistance value (the greater the amount of light, the smaller the resistance value of the photoresistor). The photosensitive element 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 joystick 2 according to the resistance value received by the photosensitive elements of the two infrared transmitting and receiving integrated tubes 4.

[0024] Example 2: Figure 2 As shown, an optical joystick module includes a PCB board 1 and a joystick 2, a reflector 3 extending from the lower part of the joystick 2, and the reflector 3 is in the shape of a cube (in other embodiments, it can also be a right-angled prism shape, an isosceles right-angled prism shape, or any other shape with two adjacent right-angled surfaces), and the two adjacent right-angled surfaces on the reflector 3 are both set as reflective surfaces, and an infrared transmitting and receiving integrated tube 4 is provided on the opposite side of each reflective surface, that is, the infrared transmitting and receiving integrated tube 4 is arranged directly opposite to the two reflective surfaces, and at the same time, the transmitting and receiving surface of the infrared transmitting and receiving integrated tube 4 faces the reflective surface corresponding to it, and the infrared transmitting and receiving integrated tube 4 is connected to the PCB board 1, and the bottom end height of the reflector 3 is located in the middle of the transmitting and receiving surface of the infrared transmitting and receiving integrated tube 4. Among them, "the two infrared transmitting and receiving integrated tubes 4 are staggered and distributed on the left and right" and "the bottom end height of the reflector 3 is located in the middle of the transmitting and receiving surface of the infrared transmitting and receiving integrated tube 4", so that a part of the emitted light of the infrared transmitting and receiving integrated tube 4 avoids the infrared light reflecting surface in the initial state, and then the joystick 2 reflects different amounts of light when it swings to different angles, so that the infrared transmitting and receiving integrated tube 4 can receive different amounts of light.
