Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic joystick technology, specifically a dual-handle electronic joystick with a locking function. Background Technology
[0002] A joystick is a relative pointing device; moving the joystick moves the target on the screen, and releasing the joystick stops the target's movement. In industrial control applications, a joystick can also serve as an absolute pointing device, where each position of the joystick maps to a specific location on the screen.
[0003] In existing technologies, a resistive approach is generally used. This approach involves moving a brush on a resistive film to change the resistance value, which in turn causes a change in the voltage drop inside the joystick. Consequently, the output voltage of the joystick can also change accordingly, and the speed can be determined based on the output voltage.
[0004] Existing resistor-based solutions are prone to resistance changes due to temperature variations, energy consumption, and dirt buildup between the slider and variable resistor, resulting in low output accuracy for the joystick.
[0005] In addition, the long-term movement of the brush can cause wear on the resistive film, which may even lead to burnout and shorten the lifespan of the control lever.
[0006] Based on this, the present invention designs a dual-handle electronic joystick with a locking function to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0028] A dual-handle electronic joystick with locking function includes a housing 1, a base 2, and a dust cover 31. The base 2 is detachably mounted on the top of the housing 1, and the dust cover 31 is detachably mounted on the top of the base 2. A left slider 5 and a right slider 14 are mounted on the base 2. A left rocker arm 10 is mounted inside the left slider 5, and a left handle 3 is connected to the top of the left rocker arm 10. A left steel ball 11 is fitted on the left rocker arm 10. A left swing arm 12 is rotatably connected inside the housing 1, and a left fixed seat 13 is rotatably connected inside the left swing arm 12. The left steel ball 11 is located inside the left fixed seat 13. The bottom end of the left rocker arm 10 passes through the left fixed seat 13 and extends into the bottom groove of the left swing arm 12. A right rocker arm 19 is mounted inside the right slider 14, and a right handle 4 is connected to the top of the right rocker arm 19. A right steel ball 20 is fitted on the right rocker arm 19. A right swing arm is also rotatably connected inside the housing 1. 21. A right fixed seat 22 is rotatably connected inside the right swing arm 21. A right steel ball 20 is set inside the right fixed seat 22. The bottom end of the right rocker arm 19 passes through the right fixed seat 22 and extends into the bottom groove of the right swing arm 21. Magnets 23 are provided on opposite sides of the left swing arm 12 and the right swing arm 21. A mounting base 26 is fixedly connected in the middle of the inside of the outer casing 1. A magnetic induction circuit board 27 adapted to the two sets of magnets 23 is provided on the mounting base 26. It can generate corresponding signals through changes in magnetic field. The Hall element on the magnetic induction circuit board 27 is coated with silicone glue, which is suitable for harsh environments such as cold storage. Then, it is transmitted to the transmission harness 29 through the data transmission circuit board 28, and finally to the control terminal. A data transmission circuit board 28 is provided between the two sets of magnetic induction circuit boards 27. A transmission harness 29 is connected to the data transmission circuit board 28, which can transmit the generated operation signals.
[0029] Furthermore, a positioning ring 24 is provided at the bottom of the right fixed base 22, through which the right joystick 19 passes. A positioning retaining ring 25 is also engaged on the right joystick 19 to limit the positioning ring 24. Only after the positioning ring 24 leaves the right fixed base 22 can the right joystick 19 deflect, so that the right handle 4 needs to be pressed before it can be operated.
[0030] Furthermore, a left spring 6, a left retaining ring seat 7, a left retaining ring 9, and a left retaining sleeve 8 are sequentially arranged on the left slider 5. The left retaining sleeve 8, the left retaining ring seat 7, the left spring 6, and the left slider 5 are fitted onto the left rocker arm 10 from top to bottom. The left retaining ring 9 is engaged with the left rocker arm 10. The left spring 6 can reset the left rocker arm 10, so that it is in a vertical state in its natural state.
[0031] Furthermore, a right spring 15, a right retaining ring seat 16, a right retaining ring 18, and a right retaining sleeve 17 are sequentially arranged on the right slider 14. The right retaining sleeve 17, the right retaining ring seat 16, the right spring 15, and the right slider 14 are fitted onto the right joystick 19 from top to bottom. The right retaining ring 18 is engaged with the right joystick 19. The right spring 15 can reset the right joystick 19, so that it is in a vertical state in its natural state.
[0032] Furthermore, a wire harness fixing block 30 is also attached to the outer casing 1, which can effectively limit the position of the transmission wire harness 29.
[0033] The implementation principle of this embodiment is as follows: By shaking the left handle 3, the left joystick 10 drives the left swing arm 12 to rotate, thereby changing the angle of the magnet 23 on the left swing arm 12. Then, through the matching magnetic induction circuit board 27, a deflection signal is emitted through the Hall effect. The signal is then transmitted to the control terminal through the transmission circuit board 28 and the transmission harness 29. Then, the right handle 4 can be pressed, causing the right joystick 19 to move downward, thereby causing the positioning ring 24 to disengage from the right fixed seat 22. Then, the right handle 4 can be shaken, thereby causing the right joystick 19 to drive the right swing arm 21 to rotate, thereby changing the angle of the magnet 23 on the right swing arm 21. Then, through the matching magnetic induction circuit board 27, a deflection signal is emitted through the Hall effect. The signal is then transmitted to the control terminal through the transmission circuit board 28 and the transmission harness 29.
