Description

Technical Field

[0001] The invention relates to a rocker, and in particular to a rocker device. 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 utility model patent with the Chinese patent announcement number CN 217181930 U and the name "a small-volume rocker potentiometer" and the utility model patent with the Chinese patent announcement number CN 219534192 U and the name "a rocker potentiometer" are both 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. Although some non-contact rocker devices have appeared, such as the utility model patent with Chinese patent announcement number CN 217442580 U, entitled "Compact rocker sensor and controller using the same", this type of rocker structure is realized by combining external Hall elements and magnets at both ends of the rocker mechanism, and its structure is relatively complex and has many accessories. Therefore, developing a non-contact rocker device with a relatively simple structure has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0021] like Figure 5 As shown, in order to realize the automatic reset of the rocker 3 after the swing, a rocker reset mechanism 5 is provided at the lower end of the rocker 3, and the rocker reset mechanism 5 includes a telescopic member 501 and a spring 502.

The bottom of the disc portion 503 of the rocker reset mechanism 5 abuts against the circuit-free area on the upper surface of the PCB board 2.

[0022] During operation, when the rocker 3 swings, the rocker 3 drives the two magnets to approach or move away from the Hall sensor through the fixing member 8, thereby determining the swing direction of the rocker 3 through the Hall signals received by the two Hall sensors. Figure 6 As shown:

[0023] When the joystick 3 swings in the positive direction of the X-axis, the joystick 3 drives the second magnet 10 to approach the second Hall sensor 7 (the position of the first magnet 9 remains basically unchanged), and the second Hall sensor 7 receives the Hall signal of the second magnet 10 approaching and transmits it to the single chip microcomputer on the mainboard of the electronic device, thereby judging that the swing direction of the joystick 3 is the "positive direction of the X-axis".

[0024] When the joystick 3 swings in the negative direction of the X-axis, the joystick 3 drives the second magnet 10 away from the second Hall sensor 7 (the position of the first magnet 9 remains basically unchanged), and the second Hall sensor 7 receives the Hall signal of the second magnet 10 moving away, and transmits it to the single chip microcomputer on the mainboard of the electronic device, thereby judging that the swing direction of the joystick 3 is the "negative direction of the X-axis".

[0025] When the joystick 3 swings in the positive direction of the Y-axis, the joystick 3 drives the first magnet 9 to move away from the first Hall sensor 6 (the position of the second magnet 10 remains basically unchanged), and the first Hall sensor 6 receives the Hall signal of the first magnet 9 moving away and transmits it to the single chip microcomputer on the mainboard of the electronic device, thereby judging that the swing direction of the joystick 3 is the "positive direction of the Y-axis".

[0026] When the joystick 3 swings in the negative direction of the Y-axis, the joystick 3 drives the first magnet 9 to approach the first Hall sensor 6 (the position of the second magnet 10 remains basically unchanged), and the first Hall sensor 6 receives the Hall signal of the approach of the first magnet 9 and transmits it to the single chip microcomputer on the mainboard of the electronic device, thereby judging that the swing direction of the joystick 3 is the "negative direction of the Y-axis".

[0027] When the joystick 3 swings between the positive direction of the X-axis and the positive direction of the Y-axis, the joystick 3 drives the first magnet 9 to move away from the first Hall sensor 6 and the second magnet 10 to move closer to the second Hall sensor 7. The first Hall sensor 6 receives the Hall signal of the first magnet 9 moving away and the second Hall sensor 7 receives the Hall signal of the second magnet 10 moving closer, and transmits it to the single chip microcomputer on the mainboard of the electronic device, thereby judging that the swing direction of the joystick 3 is "between the positive direction of the X-axis and the positive direction of the Y-axis".

[0028] When the joystick 3 swings between the positive direction of the X-axis and the negative direction of the Y-axis, the joystick 3 drives the first magnet 9 to approach the first Hall sensor 6, and the second magnet 10 to approach the second Hall sensor 7. The Hall signal of the first magnet 9 approaching received by the first Hall sensor 6 and the Hall signal of the second magnet 10 approaching received by the second Hall sensor 7 are transmitted to the single chip microcomputer on the mainboard of the electronic device, so as to judge that the swing direction of the joystick 3 is "between the positive direction of the X-axis and the negative direction of the Y-axis".

[0029] When the joystick 3 swings between the negative direction of the X-axis and the negative direction of the Y-axis, the joystick 3 drives the first magnet 9 to approach the first Hall sensor 6, while the second magnet 10 moves away from the second Hall sensor 7. The Hall signal of the first magnet 9 approaching received by the first Hall sensor 6 and the Hall signal of the second magnet 10 moving away received by the second Hall sensor 7 are transmitted to the single chip microcomputer on the mainboard of the electronic device, thereby judging that the swing direction of the joystick 3 is "between the negative direction of the X-axis and the negative direction of the Y-axis".

[0030] When the joystick 3 swings between the negative direction of the X-axis and the positive direction of the Y-axis, the joystick 3 drives the first magnet 9 to move away from the first Hall sensor 6, and the second magnet 10 to move away from the second Hall sensor 7. The Hall signal of the first magnet 9 moving away received by the first Hall sensor 6 and the Hall signal of the second magnet 10 moving away received by the second Hall sensor 7 are transmitted to the single chip microcomputer on the mainboard of the electronic device, thereby judging that the swing direction of the joystick 3 is "between the negative direction of the X-axis and the positive direction of the Y-axis".

[0031] In embodiment 1 of the present invention, two groups of "Hall sensors + magnets" are used in combination to realize the judgment of the swing direction of the joystick. Of course, in other embodiments, more than two groups of "Hall sensors + magnets" can also be used, such as four groups or eight groups.

[0032] Embodiment 2: A rocker device comprises a housing 1, a PCB board 2 and a rocker 3 are installed in the housing 1, the rocker 3 is installed in the housing 1 through a rocker mechanism 4, a rocker reset mechanism 5 is provided at the lower end of the rocker 3, the rocker reset mechanism 5 is against the circuit-free area on the upper surface of the PCB board 2, two infrared transmitting and receiving integrated tubes are provided on the PCB board 2, and the two infrared transmitting and receiving integrated tubes are distributed in two directions at a 90-degree angle, a fixing member 8 extends from the lower part of the rocker 3, and two reflective members corresponding to the two infrared transmitting and receiving integrated tubes are installed on the fixing member 8, the upper bottom surface of the reflective member is set as a reflective surface, and each reflective member is located directly above the corresponding infrared transmitting and receiving integrated tube. The rest of the structure is exactly the same as that of embodiment 1.

[0033] During operation, when the rocker 3 swings, the rocker 3 drives the reflective surfaces of the two reflective members through the fixing member 8 to increase or decrease the amount of reflected light, so that the light received by the two infrared transmitting and receiving integrated tubes increases or decreases accordingly, so that the two infrared transmitting and receiving integrated tubes generate different resistance values, which are transmitted to the single chip microcomputer on the mainboard of the electronic device, so as to determine the swing direction of the rocker 3. The basic principle is similar to that of embodiment 1, and the difference between the two is that embodiment 1 determines by the Hall signal, and embodiment 2 determines by the photosensitive signal (the amount of light received), which will not be repeated.

[0034] In Example 2, two groups of "infrared transmitting and receiving integrated tubes + reflectors" are used to determine the swing direction of the joystick. In other embodiments, more than two groups of "infrared transmitting and receiving integrated tubes + reflectors" may be used, such as four groups or eight groups.

[0035] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
