Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0017] The embodiments of this utility model relate to a small rocker arm with a stable and adjustable starting angle, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, it includes: In this embodiment, a base 7 is provided on the small rocker arm with a stable and adjustable start-up angle. The base 7 serves as the main body of this embodiment, providing the mounting position and fixing point for other components.

[0018] A positioning seat 3 is fixedly connected above the base 7. The positioning seat 3 is used to install the ball screw 4 and the copper cover 2, which assists in the radial positioning of the rotating shaft 6 and prevents the rotating shaft 6 from shaking.

[0019] A copper cover 2 is fixedly connected above the positioning seat 3. The copper cover 2 can protect the internal structure, prevent dust and foreign objects from entering, and also assist in the installation of the positioning seat 3, ensuring the coaxiality between the copper cover 2 and the positioning seat 3.

[0020] A rotating shaft 6 is inserted into the central hole of the base 7. The rotating shaft 6 passes through the switch dial 5 and the positioning seat 3 to the top of the copper cover 2. The upper end of the rotating shaft 6 is connected to the knob 1, which transmits the force of the knob 1. The middle end drives the switch dial 5, which triggers the micro switch 9. The lower end is connected to the Hall potentiometer 13, which converts the angle signal.

[0021] A knob 1 is installed in the threaded hole 601 at the top of the rotating shaft 6 with a screw. The knob 1 and the rotating shaft 6 are fixedly connected. The knob 1 is the direct operating component of the small rocker arm with a stable and adjustable start angle. The torque is transmitted to the rotating shaft 6 by manually rotating the knob 1.

[0022] A support plate 8 is fixedly connected below the base 7. The support plate 8 connects the base 7 and the signal conversion board 11, thereby enhancing the stability of the overall structure.

[0023] A micro switch 9 is fixed in the micro switch slot 901 of the base 7. The micro switch 9 is used to determine the neutral start signal. The start angle of the micro switch 9 does not change with the neutral signal of the rocker arm. When the switch plate 5 returns to the neutral position, the switch plate 5 presses the contact of the micro switch 9 and outputs an electrical signal indicating that the rocker arm is in the neutral position.

[0024] In this embodiment, a micro switch 9 is fixed in the micro switch slot 901 of the base 7. The micro switch 9 is used to determine the center position start signal. The start angle of the micro switch does not change with the change of the center position signal of the joystick. This solves the problem that in the prior art, the center position of a rotary joystick is generally provided by a ball bearing structure to meet the center position requirement. The center position of the joystick is adjusted by the electrical performance of the rotating joystick. When the center position of the joystick deviates due to mechanical backlash or electrical offset, the defined center position may be offset. Moreover, conventional rotary joysticks are generally only equipped with analog output, which cannot meet the requirements when other types of output are needed.

[0025] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2 As shown, a signal conversion board 11 is fixedly connected below the support plate 8. The signal conversion board 11 is a PWM board, a CAN output board, or a USB output board. The signal conversion board 11 receives the angle signal from the Hall potentiometer 13 and can realize signal conversion in the form of PWM signal output, CAN bus output, or USB output as required to control external devices.

[0026] To achieve the above-mentioned technical effects, such as Figure 1 , Figure 3 , Figure 4 As shown, several support copper pillars 10 are locked in several threaded holes 801 of the support plate 8; a signal conversion board 11 is fixedly connected below the several support copper pillars 10; the support copper pillars 10 are used to increase the distance between the signal conversion board 11 and the support plate 8 to prevent short circuits and strengthen the structural rigidity.

[0027] To achieve the above-mentioned technical effects, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, a terminal block 12 is soldered on one side of the signal conversion board 11. The terminal block 12 is used to connect external devices to realize power transmission between the joystick and the external devices.

[0028] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 5 As shown, a rotating shaft 1301 of Hall potentiometer 13 is fixedly connected in the central shaft hole at the bottom of the rotating shaft 6, so that when the rotating shaft 6 rotates, it drives the rotating shaft 1301 of Hall potentiometer 13 to rotate synchronously. Hall potentiometer 13 converts the mechanical rotation angle of the rotating shaft 6 into an electrical signal and transmits it to the signal conversion board 11 for processing. Hall potentiometer 13 has no wear and a long service life.

[0029] To achieve the above-mentioned technical effects, such as Figure 1 , Figure 2 and Figure 3 As shown, a shielding baffle 14 is fixedly connected below the signal conversion board 11. The shielding baffle 14 can reduce the influence of external electromagnetic interference on the signal of the Hall potentiometer 13, and ensure the stability and accuracy of the angle signal.

[0030] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 9 As shown, a ball screw positioning groove 301 is provided on the positioning seat 3. The size of the ball screw positioning groove 301 matches the shape of the ball screw 4, which can accurately fix the ball screw 4 in the corresponding position, ensuring the stable operation of the ball screw 4 and avoiding functional failure due to installation deviation or loosening after long-term use. The ball screw 4 is placed in the ball screw positioning groove 301. The steel ball inside the ball screw 4 is pressed tightly against the outer surface of the rotating shaft 6 under the spring pressure. When the knob 1 is rotated to drive the rotating shaft 6, the friction between the steel ball and the surface of the rotating shaft 6 will generate rotational damping, which can prevent accidental touch, realize angle positioning and tactile feedback, and improve operating accuracy.

[0031] To achieve the above-mentioned technical effects, such as Figure 1 , Figure 2 and Figure 3 As shown, a switch plate 5 is movably connected to the rotating shaft 6. The switch plate 5 is installed into the slot 502 of the positioning seat 3 from bottom to top. Several limiting posts 501 of the switch plate 5 are located in the arc-shaped slot 302 of the positioning seat 3. The switch plate 5 is sleeved on the rotating shaft 6 and rotates synchronously with the rotating shaft 6. When the rocker returns to the middle position, the switch plate 5 triggers the micro switch 9 to realize the detection of the middle position start signal.

[0032] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2As shown, the wire harness welding of Hall potentiometer 13 and signal conversion board 11 enables electrical conduction, establishes a signal transmission path, ensures the stability and accuracy of the angle signal, and improves the durability for long-term use.

[0033] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2 As shown, the knob 1, base 7, and switch plate 5 are made of aluminum alloy; the copper cover 2, positioning seat 3, and supporting copper column 10 are made of brass; and the rotating shaft 6, support plate 8, ball screw 4, and shielding baffle 14 are made of stainless steel.

[0034] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
