Description

Technical Field

[0001] This utility model relates to the field of rocker potentiometer technology, specifically to a rocker positioner with a switch. Background Technology

[0002] Chinese patent application publication number CN105161345A, published on December 16, 2015, discloses a 3D rotary joystick control device, including a housing, a joystick, a rocker arm assembly, and a rotation detection assembly. It also includes a reset mechanism for resetting the rocker arm assembly. The lower end of the joystick is provided with a pressure plate. The reset mechanism includes a switch seat that abuts against the pressure plate. A guide bar is provided on the support column. The switch seat is slidably connected to the guide bar. A reset spring is provided below the switch seat. Because precise guidance is achieved using the guide bar and switch seat, the entire joystick control device does not require a large space for automatic reset of the switch seat, greatly improving reset speed and reliability. Furthermore, with the precise guidance of the guide bar, since the up-and-down movement of the switch seat is a directional action, only a spring is needed for reset without interference, effectively reducing manufacturing costs. The existing technology has the following drawback: through long-term use, the feel of the operation cannot be adjusted according to personal preference, affecting the user experience, and its service life also needs improvement. Therefore, improvements are urgently needed. Utility Model Content

[0029] One side of the base 13 is integrally formed with a switch mounting base 16. On both sides of the switch mounting base 16, there are elastic buckles 17. The switch 15 is correspondingly fitted into the switch mounting base 16, and the elastic buckles 17 on both sides abut against the switch 15.

[0030] The upper cover 12 has upper semi-arc bearing portions 32 formed on the lower part of each of its four sides, and the base 13 has lower semi-arc bearing portions 29 formed on the upper part of each of its four sides.

When it is necessary to adjust the applied force of the rocker arm, a hexagonal wrench is inserted into the hexagonal groove 50 and the limiting pressure block 31 is rotated. By rotating the relative height of the limiting pressure block 20 in the hollow inner cavity 36, the pressure applied by the hollow spring pressure seat 37 to the return spring 39 is changed, thereby adjusting the pressure applied by the return spring 39 to the pressure plate 41.

[0034] A support pad 48 is coaxially disposed on the upper surface of the inner cavity of the base 13, corresponding to the position of the pressure plate 41. A conical positioning protrusion 42 is formed in the middle of the support pad 48. A conical groove 40 is formed in the center of the bottom of the pressure plate 41, which cooperates with the conical positioning protrusion 42.

The upper buckle hole clearance groove 30, the lower buckle hole clearance groove 34 and the outer shell 11 surround and form a fastening space for storing the buckle arm 49.

[0036] The outer shell 11 has four limiting slots 45 on its upper surface, and the upper cover 12 has four limiting protrusions 46 on its upper surface that engage with the limiting slots 45. This structural design makes the structure more compact.

[0037] The bottom of the outer casing 11 has inner folding blocks 43 that abut against the base 13 on all four sides.

[0038] The inner shell structure 14 is made of plastic, while the outer shell 11 is made of metal. This structural design reduces wear caused by friction and increases the overall rigidity of the structure, thereby extending its service life.

[0039] In this embodiment, the top cover is quickly assembled and positioned with the base and the outer shell via the first and second mounting protrusions, respectively. The switch is fitted into the switch mounting base, and the elastic buckles on both sides abut against the switch for fixation. The first and second rotary output components are fastened to the fastening space via buckle arms. The bottom of the four sides of the outer shell has inner folding blocks that abut against the base, allowing the outer shell to be stably connected to the inner shell structure. The four sides of the base have limiting slots that abut against the outer shell. This structural design makes the present invention simple and easy to assemble. The main body of this structure consists of an outer shell and an inner shell structure, and the inner shell structure includes the top cover and the base, which directly increases the overall rigidity of the main body. Furthermore, the top cover has a first reinforcing part formed on its four sides, and the base has a second reinforcing part formed on its four sides, which directly strengthens the strength of the rotary limiting bearing hole, thereby greatly improving the service life.
