Description

Technical Field

[0001] This utility model relates to the field of rocker potentiometer technology, specifically to a rocker positioner with a switch for easy assembly. 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 drawbacks: the feel of the operation cannot be adjusted according to personal preference, and the service life of the existing technology needs improvement over long-term use. Therefore, improvements are urgently needed. Utility Model Content

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0029] Reference Figure 1-5As shown: A rocker positioner with a switch for easy assembly includes a rocker assembly 43, a housing 13 with an opening on the top surface, a switch 16, a first rotation output assembly 17, a second rotation output assembly 15, and an inner shell structure 34; the rocker assembly 43 includes a rocker 10, an upper rocker arm 12, and a lower rocker arm 11. Mounting shafts 46 are provided on opposite sides of the outer side of the rocker 10. The lower part of the rocker 10 passes through the upper rocker arm 12 and the lower rocker arm 11 in sequence and is rotatably connected to the lower rocker arm 11 through the mounting shafts 46 on both sides. The outer shell 13 is correspondingly covered on the outer surface of the inner shell structure 34. The lower part of the rocker arm assembly 43 is installed in the inner cavity of the outer shell 13. The first rotation output assembly 17 and the second rotation output assembly 15 are respectively installed on adjacent sides of the outer side of the inner shell structure 34. The switch 16 is installed on the outer side of the inner shell structure 34 and on the opposite side of the second rotation output assembly 15. One end of the lower rocker arm 11 is connected to the second rotation output assembly 15, and the other end of the lower rocker arm 11 is connected to a pressing block 44 that cooperates with the switch 16. One end of the upper rocker arm 12 is rotatably connected to the inner shell structure 34, and the other end of the upper rocker arm 12 is connected to the first rotation output assembly 17.

[0030] The rocker arm 10 has a first hollow inner cavity 29, the upper inner diameter of which is smaller than its lower inner diameter. A limiting block 31, a hollow spring seat 32, a return spring 35, and a pressure plate 37 are disposed within the first hollow inner cavity 29. An internal thread 30 is provided on the upper part of the inner wall of the first hollow inner cavity 29, and an external thread matching the internal thread 30 is formed on the outer side of the limiting block 31. The upper part of the pressure plate 37 is coaxially fitted into the bottom of the first hollow inner cavity 29, and the lower part of the pressure plate 37 extends out of the first hollow inner cavity 29. A guide rod 36 is coaxially arranged in the inner cavity of 7 and the first hollow inner cavity 29. A hollow spring pressure seat 32 is arranged on the lower surface of the limiting pressure block 31. The upper part of the guide rod 36 extends into the inner cavity of the hollow spring pressure seat 32. The outer diameter of the guide rod 36 is equal to the inner diameter of the hollow spring pressure seat 32.

[0034] The upper cover 14 has upper semi-arc bearing parts 23 formed on the lower part of all four sides, and the base 18 has lower semi-arc bearing parts 45 formed on the upper part of all four sides. The upper semi-arc bearing parts 23 and lower semi-arc bearing parts 45 on the four sides respectively form the rotation limit bearing parts of the upper rocker arm 12 and the lower rocker arm 11.

[0035] A fitting groove 22 is formed between the upper part of the limiting seat 24 and the upper cover 14, and the lower part of one side of the outer shell 13 is correspondingly fitted into the fitting groove 22. This allows the outer shell 13 and the upper cover 14 to be tightly assembled, improving the compactness of the assembly.

[0036] The inner walls of the first rotating output component 17 and the second rotating output component 15 are provided with first fastening blocks 39 on opposite sides; the upper cover 14 has a lower fastening hole clearance groove 40 at the position corresponding to the first fastening block 39, and the base 18 has an upper fastening hole clearance groove 42 at the position corresponding to the first fastening block 39.

[0039] The inner shell structure 34 is made of plastic, and the outer shell 13 is made of metal. This structural design reduces the wear of the rocker assembly 43 after multiple rotation operations, thereby increasing its service life.

[0040] The top cover 14 has a first arc-shaped reinforcing part 48 at the position corresponding to each upper semi-arc bearing part 23. The base 18 has a second arc-shaped reinforcing part 49 at the position corresponding to each lower semi-arc bearing part 45. By providing the first arc-shaped reinforcing part 48 and the second arc-shaped reinforcing part 49, the strength of the rotating limiting bearing part is enhanced, thereby improving the service life of this structure.

[0041] In this embodiment, the upper cover is quickly assembled and positioned with the base and the outer shell via the first and second mounting protrusions, respectively. The switch is correspondingly fitted into the switch mounting base and fixed by the limiting seat contacting the switch. The first and second rotary output components are fastened and fixed to the fastening space by the first fastening block. The first and second rotary output components are quickly positioned and installed by the cooperation of the positioning pin and the positioning pin guide groove. The bottom of the four sides of the outer shell has inner folding blocks that contact the base, so that the outer shell can be stably connected to the inner shell structure. Through this structural design, the structure of this utility model is simple and easy to assemble. The main body of this structure is mainly composed of an outer shell and an inner shell structure. The inner shell structure includes an upper cover and a base. The upper semi-arc bearing part and the lower semi-arc bearing part respectively form the rotation limiting support parts of the upper rocker arm and the lower rocker arm. On the one hand, it directly increases the overall rigidity of the main body, and on the other hand, it improves the strength of the rotation limiting support parts, thereby improving the service life.
