3D rotary input device with high detection accuracy

Abstract

The invention relates to the technical field of rotary inputting devices, in particular to a three-dimensional rotary inputting device with high detection precision. The inputting device comprises an upper rocker arm elastic mechanism and a lower rocker arm elastic mechanism, wherein the upper rocker arm elastic mechanism and the lower rocker arm elastic mechanism are independent of each other, so that rotation of an upper rocker arm does not affect the lower rocker arm elastic mechanism and accordingly does not affect a lower rocker arm, generation of tiny error signals is avoided, the detection precision is improved, and the lower rocker arm is in the similar way. In addition, the three-dimensional rotary inputting device is provided with multiple elastic mechanisms, so that the effect that the rocker arms are stressed by different resistance when toppling in the different directions is conveniently achieved by making elastic coefficients of all the elastic mechanisms be different, and then the product meets the human engineering requirement better.

Description

technical field [0001] The invention relates to the technical field of rotary input devices, in particular to a 3D rotary input device with high detection accuracy. Background technique [0002] The 3D rotary input device is commonly referred to as a rocker switch, which is mainly used in electronic products such as gamepads. It generally includes a rocker that can be tilted and outputs a corresponding signal according to the tilting operation of the rocker by the operator. [0003] As disclosed in the patent document with the publication number CN1885464A, the current 3D rotary input device generally includes a rocker for operation, a rocker (including two rocker arms arranged perpendicularly to each other) and a detection rocker The detection device of the rotation amount, the detection device will output the corresponding output signal according to the rotation amount of the rocker arm, and at the same time, a reset mechanism is also provided under the rocker arm to ensur...

AI Technical Summary

Problems solved by technology

[0004] (1) Since the reset mechanism has a certain supporting and balancing effect on both the upper rocker arm and the lower rocker arm, when the upper rocker arm rotates and the reset mechanism deforms, the supporting effect of the reset mechanism on the lower rocker arm will be affected to a certain extent. As a result, the lower rocker arm is prone to slight rotation due to external vibrations and other reasons. In products with higher and higher detection sensitivity, this slight rotation will also be detected and the final detection result cannot accurately reflect the operator's dumping. Operational situation, same problem exists when the lower rocker arm is turned

[0005] (2) Since the upper rocker arm and the lower rocker arm are connected to the same reset mechanism, the resistance to the rotation of the upper rocker arm and the lower rocker arm is consistent (related to the elastic coefficient of the reset mechanism), so the user dumps the rocker During operation, the resistance it receives is only related to the magnitude of the dumping, and has nothing to do with the direction of the dumping. However, according to ergonomics, when the human thumb rotates (dumping operation) the rocker of the product, the resistance in different directions should be inconsistent It is better, because the human thumb is easier to use force when it is in the direction of the finger, and obviously, the current 3D rotary input device cannot achieve different effects of resistance in different directions
