Abstract
Description
Technical Field
[0001] This utility model relates to the field of input devices, specifically to a magnetic induction joystick. Background Technology
[0002] Joysticks, as a common manual control input device, are widely used in game controllers, drone remote controllers, industrial control equipment, and other fields. Traditional joysticks often use potentiometers to detect the joystick's swing angle. Potentiometers change the resistance value through mechanical contact between brushes and a resistive diaphragm, thereby outputting different voltage signals. However, this contact-based wear leads to a limited lifespan for the potentiometer, issues such as decreased accuracy and poor contact, and susceptibility to dust and moisture.
[0003] To overcome the aforementioned drawbacks, non-contact joysticks employing the principle of magnetic induction have emerged on the market. These typically use magnets on the joystick and Hall effect sensors on the base to detect changes in the magnetic field, thereby determining the joystick's position. While this solves the wear problem, existing magnetic induction joysticks often have complex structures, require high assembly precision, and, when integrating push-button functionality, usually necessitate the design of independent, complex mechanical structures. This increases the number of parts and cost, and also raises the assembly difficulty.
[0004] Therefore, there is an urgent need for a magnetic induction joystick solution with a more optimized structure, higher integration, and better reliability. Utility Model Content
[0005] To address the aforementioned problems, this utility model aims to provide a magnetic induction rocker that is compact in structure, highly integrated, has a long lifespan, and is easy to assemble.
[0006] To achieve this technical objective, the present invention provides a magnetic induction rocker, comprising a housing, a rocker assembly, a base plate, and a swing signal generating assembly. The rocker assembly includes a rocker shaft oscillatingly disposed within the housing, a first linkage member and a second linkage member linked with and oscillating with the rocker shaft, and a reset member for resetting the rocker shaft. The swing signal generating assembly includes a magnetic element and a magnetic field sensing element. The magnetic element is disposed on the first linkage member and / or the second linkage member, and the magnetic field sensing element is disposed on the base plate. The magnetic element moves relative to the magnetic field sensing element as the linkage member oscillates, thereby causing the magnetic field sensing element to generate an electrical signal indicating the swing position of the rocker shaft. The invention also includes a press signal generating assembly, wherein the rocker shaft can be pressed to trigger the press signal generating assembly to generate a confirmation signal.
[0007] Preferably, a rocker arm seat is also included, wherein the first linkage and the second linkage are pivotally mounted on the rocker arm seat via a pivot structure.
[0008] Preferably, the pivot structure includes a first pivot shaft located at both ends of the first linkage member, a second pivot shaft located at both ends of the second linkage member, and a support portion located on the rocker arm seat that cooperates with the first pivot shaft and the second pivot shaft.
[0009] Preferably, the first linkage member and / or the second linkage member are provided with an extension portion extending toward the base plate, and the magnetic member is mounted on the extension portion.
[0010] Preferably, the extension is provided with a mounting groove or mounting hole for accommodating the magnetic component.
[0011] Preferably, the press signal generating component includes a movable member disposed on the rocker arm seat and a switching element disposed on the base plate; when the rocker arm shaft is pressed, it drives the movable member to move axially, thereby triggering the switching element.
[0012] Preferably, the rocker arm seat is provided with a guide groove or guide hole for guiding the movement of the movable part.
[0013] Preferably, the reset member includes a rod-shaped portion connected to the rocker shaft and an elastic portion disposed at the bottom end of the rod-shaped portion.
[0014] Preferably, the magnetic field sensing element is a Hall sensor or a TMR sensor.
[0015] The advantages of this invention are: it employs non-contact detection using magnetic components and magnetic field sensing elements, resulting in a compact overall structure. The magnetic components are located on the extension of the linkage component, saving space and achieving high integration. The modular design simplifies assembly, increases production efficiency, and reduces costs. Attached Figure Description

Detailed Implementation
[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. To provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; these embodiments are only some embodiments of the present invention; other embodiments obtained based on this application without creative effort are all within the scope of protection of the present invention.
[0024] In the following embodiments, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "top / bottom," etc., are all based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of clearly describing this embodiment. They do not indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application. At the same time, the terms "first" and "second" in the embodiments are only used for descriptive purposes and do not represent an indication or implication of relative importance.
[0025] like Figure 1-7 As shown, the specific embodiment of this utility model is a magnetic induction rocker provided by this utility model, which mainly includes a housing 1, a rocker assembly, a base plate 8, a swing signal generating assembly, and a press signal generating assembly.
[0026] The rocker assembly is the core moving component. The upper part of the rocker shaft 2 extends out of the housing 1 for user operation, while the lower part is oscillatingly disposed within the housing 1. The first linkage 3 and the second linkage 4 are arranged crosswise and linked to the bottom of the rocker shaft 2 (the rocker shaft 2 is engaged with one of the linkages via a pin), so that the first linkage 3 and the second linkage 4 can move accordingly when the rocker shaft 2 swings in any direction. To provide support for the linkages, a rocker seat 5 is also fixed inside the housing 1. The first linkage 3 has a first pivot shaft 31 at both ends, and the second linkage 4 has a second pivot shaft 41 at both ends. The rocker seat 5 has a support portion 51 (preferably a U-shaped groove in this embodiment) that mates with these pivot shafts, thus forming a universal joint-type pivot structure that allows the linkages to swing in the X and Y directions.
[0027] A swing signal generating component is used to detect the swing angle of the joystick. The first linkage 3 and the second linkage 4 each have an integrally formed extension extending towards the base plate 8. Each extension has a mounting groove at its end, within which a magnetic element 7 is fixedly mounted. On the base plate 8, directly below the movement trajectory of each magnetic element 7, a magnetic field sensing element 9 (Hall sensor or TMR sensor) is mounted. When the joystick swings, the linkage moves the magnetic element 7 closer to or further away from the Hall sensor below. By changing the magnetic field strength sensed by the Hall sensor, a changing voltage signal is output, allowing for precise calculation of the two-dimensional swing position of the joystick.
[0028] The reset component 6 in this embodiment includes a rod-shaped part 61 (connecting rod) nested inside the rocker shaft 2 and an elastic part 62 (silicone base) located at its bottom end. When the rocker swings, it squeezes the elastic part 62 to deform it; after it is released, the elastic force of the elastic part 62 to restore its original shape will push the entire rocker assembly back to the center position.
[0029] The press signal generating component is used to realize the pressing function of the joystick. The joystick base 5 is provided with a guide groove 52, and the movable part 10 is installed in the guide groove 52 and can slide up and down. The top of the movable part 10 abuts against the bottom of the first pivot shaft 31 (or the second pivot shaft 41). On the base plate 8, directly below the movable part 10, a switching element 11 (such as a dome switch) is provided.
[0030] When the rocker arm 2 is pressed vertically downwards, the force is transmitted to the pivot shaft via the linkage. The pivot shaft moves downwards, pushing the movable part 10 to slide downwards along the guide groove 52, ultimately triggering the switch element 11 at the bottom to generate a confirmation signal. After being released, the elastic force of the switch element 11 will push the movable part 10 back to its original position.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
