Description

Technical Field

[0001] The utility model relates to the technical field of potentiometers, in particular to a multi-directional non-contact rocker. Background Art

[0002] The Chinese patent authorization announcement number is CN117899448A, and the authorization announcement date is April 19, 2024. The utility model is named "A multi-directional input device," which includes a housing, an operating rod, a magnetic member, a circuit board, a support seat, a reset assembly, a spring, a pressing member, and a magnetic sensing chip. The operating rod includes an operating portion and a shaking portion connected to each other, the reset assembly includes a pressure plate and a spring, and the magnetic sensing chip includes a chip body and a sensing portion. The centers of the shaking portion, the magnetic member, the pressing member, the spring, and the sensing portion are all located on the same vertical line. When the operating rod is shaken or pressed to drive the magnetic member to move in any direction relative to the sensing portion, the sensing portion senses the change in magnetic force of the magnetic member and outputs a magnetic field change signal, so that the multi-directional input device can accurately and promptly feedback the direction and amount of movement of the operating rod, thereby improving the user experience. The defects of this existing technology are: the pressure plate is set as a flat structure, which will affect the centering force of the operating rod during actual operation, thereby reducing the accuracy of the operating rod's return; the pressing feel is generated by the contact between the pressing member and the spring sheet, but during actual operation, the pressing feel is generated because the non-operating rod directly contacts the spring sheet, resulting in a certain time lag in the generation of the feel. In view of this situation, improvement is urgently needed. Utility Model Content

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0027] Reference Figure 1-4 As shown: A multi-directional non-contact rocker, including a base 28, a cover shell 14, a nest piece 23, a support frame 21, a magnetic member 20, a return spring 19, a pressure ring 18, a rocker structure 40, a non-contact Hall sensor 25, a PCB board 24, and a pressure plate 27;

[0028] The cover shell 14 is covered on the base 28 to form an assembly space, and the return spring 19 is arranged in the assembly space; the top of the cover shell 14 is provided with an escape hole 16 for the rocker structure 40 to move; the inner side wall of the escape hole 16 is formed with an arc surface A;

[0029] The PCB board 24 is mounted at the bottom of the inner cavity of the base 28. The pressure plate 27 is correspondingly arranged on the upper surface of the PCB board 24. A hollow portion A is defined in the middle of the pressure plate 27. The non-contact Hall effect sensor 25 is eccentrically mounted on the PCB board 24 through the hollow portion A. A hollow annular boss 26 is formed on the pressure plate 27 at the position of the hollow portion A. A nesting piece receiving groove 31 is formed on the upper surface of the hollow annular boss 26. The nesting piece 23 is correspondingly covered and disposed in the nesting piece receiving groove 31. A gap is formed between the nesting piece 23 and the non-contact Hall effect sensor 25. A support frame 21 is provided on the upper surface of the hollow annular boss 26. A hollow portion B22 is defined in the middle of the support frame 21 for the bottom of the rocker structure 40 to pass through. The return spring 19 is sleeved on the outside of the support frame 21.

[0030] The pressure ring 18 is disposed between the top of the inner cavity of the cover shell 14 and the top of the return spring 19; the top of the return spring 19 contacts the return spring 19, and the bottom of the return spring 19 contacts the upper surface of the pressure plate 27; a hollow portion C38 is provided in the middle of the pressure ring 18 for the rocker structure 40 to pass through; the bottom of the rocker structure 40 passes through the avoidance hole 16, the hollow portion C38, and the hollow portion B22 in sequence; the magnetic member 20, the hollow portion C38, the hollow portion B22, and the nest piece receiving groove 31 are coaxially arranged;

[0031] The rocker structure 40 includes a rocker 10, a rocking portion 33, and a plastic sleeve 11. The rocking portion 33 is integrally formed at the lower portion of the rocker 10. The bottom of the rocker 10 forms an extended section. The bottom of the extended section has a magnetic component receiving groove 42 for receiving the magnetic component 20. The plastic sleeve 11 is correspondingly mounted outside the extended section. The outer side surface of the rocking portion 33 is formed with an arcuate surface B that cooperates with the arcuate surface A. The magnetic component 20 is correspondingly disposed in the magnetic component receiving groove 42.

[0032] A concave platform 35 is formed on the upper surface of the pressure ring 18, coaxial with the hollow portion C38. A contact protrusion 36 is formed on the top of the inner side surface of the cover 14, corresponding to the concave platform 35. The arcuate surface A of the contact protrusion 36 cooperates with the arcuate surface B, and the inner arcuate surface C of the contact protrusion 36 cooperates with the inclined transition surface of the concave platform 35. The lower surface of the rocking portion 33 is in contact with the upper surface of the concave platform 35. The first coil of the return spring 19 is correspondingly mounted on the outer surface of the concave platform 35, and a gap is formed between the lower surface of the contact protrusion 36 and the upper surface of the concave platform 35. This structural arrangement allows the first coil of the return spring to be positioned within the range between the concave platform and the cover, and the contact protrusion is also positioned between the inclined transition surface of the concave platform and the outer side surface of the rocking portion. This ensures that the rocker has good centering force and directly improves the return accuracy of the rocker. During actual operation, the joystick is shaken or pressed to drive the magnetic part 20 to move along any direction of X, Y, or Z relative to the non-contact Hall sensor 25. The non-contact Hall sensor 25 senses the magnetic force transformation of the magnetic part 20 and outputs a magnetic field change signal.

[0033] Mounting bumps 13 are formed on opposite sides of the cover 14. An upper rocker arm 12 is positioned above the cover 14. Lowered buckle surfaces 32 corresponding to the mounting bumps 13 are formed on opposite sides of the upper rocker arm 12 along its length. Both lower buckle surfaces 32 have buckle holes 15 for inserting the mounting bumps 13. A limiting space 39 is defined along the upper surface of the upper rocker arm 12 along its length to limit the range of motion of the rocker arm 10. A gap is formed between the upper surface of the cover 14 and the lower surface of the upper rocker arm 12. This facilitates assembly and disassembly of the upper rocker arm 12 and prevents the rocker arm from rotating 360 degrees, thereby limiting its rotational direction.

[0034] The base 28 is provided with fastening portions 30 on all four sides, and fastening projections 17 are formed on the outer side of the cover 14 at positions corresponding to the fastening portions 30. When assembled, the fastening portions 30 engage with the corresponding fastening projections 17. The mating mounting structure of the fastening portions 30 and the fastening projections 17 improves assembly convenience, thereby directly improving assembly efficiency.

[0035] Anti-detachment protrusions 34 are provided on opposite sides of the rocker 10 near the rocking portion 33 to prevent the upper rocker arm 12 from detaching.

[0036] A mounting pin 41 is coaxially arranged in the magnetic member receiving groove 42. The mounting pin 41 is correspondingly inserted into the top of the magnetic member 20 and makes interference contact with the insertion hole of the mounting pin 41. With this structural setting, there is no need to glue the magnetic member 20, saving processing steps and improving assembly efficiency.

[0037] A gap is formed between the support frame 21 and the upper surface of the pressing plate 27 .

[0038] The outer diameter of the hollow annular boss 26 is equal to the inner diameter of the lower portion of the support frame 21 , thereby improving the compactness of the assembly structure.

[0039] An upper portion of the inner wall of the hollow portion B22 is formed with an arc-shaped surface D that matches the curvature of the outer surface of the plastic sleeve 11 .

[0040] In this embodiment, the bottom of the joystick forms an extended section, and the plastic sleeve is correspondingly arranged outside the extended section. When the joystick is pressed, the plastic sleeve directly contacts the wedge piece to immediately produce a good pressing feel, and the upper part of the inner wall of the hollow part B is formed with an arc surface D that matches the curvature of the outer surface of the plastic sleeve. The plastic sleeve is in friction contact within the range of the arc surface D, thereby ensuring a good control feel when pressing the joystick.

[0041] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
