Detailed Implementation

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0029] like Figures 1-4 As shown, a single-axis analog rocker arm of this utility model is installed on the main housing of the device and includes: a housing assembly 1, a rocker arm assembly 2, and a potentiometer assembly 3;

[0030] The housing assembly 1 includes: a housing 11 and a connecting base 12;

[0031] The outer casing 11 is screwed to the main casing. The outer casing 11 has a hollow structure and an opening at the bottom. The potentiometer assembly 3 is located inside the outer casing 11. The rocker arm assembly 2 is located on the outer casing 11 and is used to drive the potentiometer assembly 3. The connector 12 is located at the opening at the bottom of the outer casing 11 and is used to connect to the mainboard inside the device.

[0032] The rocker arm assembly 2 includes: a handle, a rotating shaft 23, and a reset mechanism;

[0033] One end of the handle is connected to a rotating shaft 23, which extends into the housing 11 and is connected to the potentiometer assembly 3. The reset mechanism is used to reset the handle.

[0034] When the joystick needs to be replaced, this application allows the joystick to be removed from the main housing by unscrewing the screws connecting the outer casing 11 to the main housing and then disconnecting the connection cable between the connector 12 and the mainboard inside the device. This facilitates quick replacement of the joystick and reduces the time spent on replacing it.

[0035] like Figure 2 As shown, the handle includes: a left handle 21 and a right handle 22;

[0036] The left handle 21 and the right handle 22 are connected in conjunction. One end of the left handle 21 is connected to the rotating shaft 23, and one end of the right handle 22 has a circular hole. The outer casing 11 has a cylinder corresponding to the circular hole, and the cylinder is connected to the circular hole. By pushing the handle, the rotating shaft 23 is rotated, which drives the potentiometer assembly 3.

[0037] like Figures 2-3 As shown, the swing arm assembly 2 includes: a transition member 24 and a limiting plate 25;

[0038] The transition piece 24 has a connecting sleeve on one side and a boss on the other side. The connecting sleeve is connected to the rotating shaft 23. The boss passes through the limiting plate 25 and is connected to the potentiometer assembly 3. The limiting plate 25 has a fan-shaped hole. The transition piece 24 is located in the fan-shaped hole of the limiting plate 25. The fan-shaped hole is set according to the swing path of the transition piece 24.

[0039] During the process of pushing the handle to rotate the shaft 23, the shaft 23 drives the transition piece 24 to rotate, causing the transition piece 24 to rotate within the fan-shaped hole. The fan-shaped hole can limit the rotation angle of the transition piece 24, enabling it to effectively drive the potentiometer assembly 3.

[0040] like Figures 2-3 As shown, the reset mechanism includes: a first reset plate 27, a second reset plate 28, and a torsion spring 26;

[0041] The first reset plate 27 is disposed at one end of the transition member 24, the second reset plate 28 is disposed on the limiting plate 25 and correspondingly disposed below the first reset plate 27, the torsion spring 26 is sleeved on the connecting sleeve of the transition member 24, the torsion spring 26 has two pins, and the first reset plate 27 and the second reset plate 28 are both located between the two pins.

[0042] During the rotation of the transition piece 24, the first reset plate 27 rotates on the transition piece 24, causing the first reset plate 27 and the second reset plate 28 to become misaligned. When the force pushing the handle disappears, the pin will push the first reset plate 27 to reset the first reset plate 27, thereby resetting the transition piece 24 and then resetting the handle.

[0043] like Figures 2-4As shown, the potentiometer assembly 3 includes: a potentiometer housing 31, a brush holder 32, and a first circuit board 33;

[0044] The potentiometer housing 31 is connected to the first circuit board 33. The brush holder 32 is disposed inside the potentiometer housing 31. One end of the brush holder 32 is connected to the transition member 24. A brush plate is provided on one side of the brush holder 32. A resistor layer 34 is provided on the first circuit board 33 corresponding to the brush plate. A pin header 35 is provided at the lower end of the first circuit board 33.

[0045] The potentiometer assembly 3 further includes: a second circuit board 36;

[0046] The potentiometer housing 31 is located at the lower end of the second circuit board 36, which has a solder pad hole. The pin header 35 is soldered to the solder pad hole, and the connector 12 is located below the second circuit board 36.

[0047] During the rotation of the transition piece 24, the brush holder 32 will rotate, causing the brushes on the brush holder 32 to move on the resistor layer 34, thereby changing the resistance value and outputting an electrical signal.

[0048] like Figures 1-3 As shown, the outer casing assembly 1 includes: a connecting ring 13, a sealing gasket 14, and an outer casing fixing plate 15;

[0049] The connecting ring 13 is located on the outside of the outer shell 11. The sealing gasket 14 and the outer shell fixing plate 15 are both sleeved on the outside of the outer shell 11. The sealing gasket 14 is located between the connecting ring 13 and the outer shell fixing plate 15. The connecting ring 13, the sealing gasket 14 and the outer shell fixing plate 15 are connected by screws. The main shell is connected between the sealing gasket 14 and the outer shell fixing plate 15.

[0050] The sealing gasket 14 is located between the connecting ring 13 and the main housing, serving to prevent dust and water penetration. In this embodiment, adhesive is applied to the inside of the outer shell fixing plate 15, allowing the outer shell fixing plate 15 to be adhered to the inside of the main housing. Bolts can then be used to fix the connecting ring 13, sealing gasket 14, main housing, and outer shell fixing plate 15 together, making the connection structure more stable.

[0051] like Figures 1-2 As shown, the top of the outer casing 11 is wavy, and there are two protrusions on both sides of the top of the outer casing 11 to limit the rotation angle of the handle.

[0052] The rotation angle of the handle is limited by two protrusions on the top of the outer casing 11, which prevents excessive force from turning the handle and damaging the shaft 23.

[0053] Above, refer to Figures 1-4This invention describes a single-axis analog joystick according to an embodiment of the present invention. When the joystick needs to be replaced, the joystick can be removed from the main housing by unscrewing the screws connecting the outer casing 11 to the main housing and then disconnecting the connection cable between the connector 12 and the main board inside the device. This facilitates quick replacement of the joystick and reduces the time spent on replacing the joystick.
