Description

Technical Field

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

[0002] The publication number is CN117899448A, the publication date is April 19, 2024, and the name of the invention is a multi-directional input device, which includes a shell, an operating rod, a magnetic part, a circuit board, a support seat, a reset assembly, a spring, a pressing part and a magnetic sensing chip, wherein the operating rod includes an operating part and a shaking part 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 part. The centers of the shaking part, the magnetic part, the pressing part, the spring and the sensing part are all located on the same vertical line, and when the operating rod is shaken or pressed to drive the magnetic part to move relative to the sensing part in any direction, the sensing part senses the change in the magnetic force of the magnetic part and outputs a magnetic field change signal, so that the multi-directional input device can accurately and timely feedback the direction and amount of movement of the operating rod, thereby improving the user experience. The defects of the prior art are: the pressure plate is set as a plane structure, which will affect the centering force of the operating rod in actual operation, thereby reducing the accuracy of the return of the operating rod; the pressing feel is generated by the contact between the pressing member and the spring sheet, and in 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. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with examples 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 reset 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 installed at the bottom of the inner cavity of the base 28, and the pressure plate 27 is correspondingly arranged on the upper surface of the PCB board 24. A hollow portion A is opened in the middle of the pressure plate 27, and the non-contact Hall sensor 25 penetrates the hollow portion A and is eccentrically installed on the PCB board 24; the pressure plate 27 is located at the position of the hollow portion A to form a hollow annular boss 26; the upper surface of the hollow annular boss 26 is formed with a nest piece storage groove 31, and the nest piece 23 is correspondingly covered in the nest piece storage groove 31; a gap is formed between the nest piece 23 and the non-contact Hall sensor 25; the upper surface of the hollow annular boss 26 is provided with a support frame 21, and a hollow portion B22 for the bottom of the rocker structure 40 to penetrate is opened in the middle of the support frame 21; the reset spring 19 is sleeved outside the support frame 21;

[0030] The pressure ring 18 is arranged between the top of the inner cavity of the cover shell 14 and the top of the reset spring 19; the top of the reset spring 19 is in contact with the reset spring 19, and the bottom of the reset spring 19 is in contact with the upper surface of the pressure plate 27; the middle of the pressure ring 18 is provided with a hollow portion C38 for the rocker structure 40 to penetrate; the bottom of the rocker structure 40 is sequentially penetrated by the avoidance hole 16, the hollow portion C38, and the hollow portion B22; the magnetic member 20, the hollow portion C38, the hollow portion B22, and the nest piece storage 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 extension section. The bottom of the extension section is provided with a magnetic component receiving groove 42 for receiving the magnetic component 20. The plastic sleeve 11 is correspondingly sleeved outside the extension section. The outer side surface of the rocking portion 33 is formed with an arc surface B that matches the arc surface A. The magnetic component 20 is correspondingly arranged in the magnetic component receiving groove 42.

[0032] The upper surface of the pressure ring 18 is formed with a concave platform 35 coaxial with the hollow portion C38, and a contact protrusion 36 is formed at the top of the inner side surface of the cover shell 14 at a position corresponding to the concave platform 35. The arc surface A of the contact protrusion 36 is matched with the arc surface B, and the inner arc surface C of the contact protrusion 36 is matched 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 circle of the reset spring 19 is correspondingly sleeved on the outer side 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. Through such a structural setting, the first circle of the reset spring is limited within the range between the concave platform and the cover shell, and the contact protrusion is also limited between the inclined transition surface of the concave platform and the outer side surface of the rocking portion, which directly improves the return accuracy of the rocking arm on the basis of ensuring that the rocking arm has a good centering force. In 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 change of the magnetic part 20 and outputs a magnetic field change signal.

[0033] Mounting convex particles 13 are formed on opposite sides of the cover shell 14, and an upper rocker arm 12 is arranged above the cover shell 14.

A gap is formed between the upper surface of the cover shell 14 and the lower surface of the upper rocker arm 12. On the one hand, it is convenient to disassemble and assemble the upper rocker arm 12, and on the other hand, by providing the upper rocker arm 12, the rocker arm is prevented from rotating 360°, that is, the rotation direction of the rocker arm is limited.

[0034] The four sides of the base 28 are provided with fastening parts 30, and fastening protrusions 17 are formed on the outer side of the cover shell 14 and at positions corresponding to the fastening parts 30; when in the assembled state, the fastening parts 30 are correspondingly hooked on the fastening protrusions 17. The matching installation structure of the fastening parts 30 and the fastening protrusions 17 improves the convenience of assembly, thereby directly improving the 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, and the mounting pin 41 is correspondingly inserted into the top of the magnetic member 20 and is in interference contact with the insertion hole of the mounting pin 41. With such a structural setting, the magnetic member 20 does not need to be glued and fixed, which saves processing steps and improves 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 arc surface D matching the arc of the outer surface of the plastic sleeve 11 is formed on the upper portion of the inner wall of the hollow portion B22 .

[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 portion 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 the joystick is pressed.

[0041] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention.
