Key structure and input device

Abstract

The invention relates to a key structure and an input device using the same. The key structure comprises a keycap layer having a keycap area, a support layer arranged below the keycap layer, a force transfer unit arranged below the keycap layer, and an induction unit arranged below the force transfer unit. The support layer has an opening corresponding to the keycap area, and the force transfer unit has a protruding part which is disposed in the opening. When a pressing force is applied externally, the pressing force is transferred downward by the force transfer unit, and the bottom side of the protruding part presses the induction unit to trigger the induction unit to output a trigger signal. According to the invention, the key structure is thin due to the laminating structure; and meanwhile, the force transfer unit is used as a force transfer layer, and the support layer is used as a support structure layer, which can ensure that a touch generator has an appropriate vibration space and reduce the probability that the induction unit is triggered falsely.

Description

technical field [0001] The present invention generally relates to a key structure, and specifically, the present invention relates to a key structure with a force transmission path design and an input device with the key structure. Background technique [0002] With the increasingly high requirements for the thinning of electronic devices, the height of the applicable key structure is significantly reduced. Therefore, the conventional mechanical key structure with a large pressing stroke has been gradually replaced by small stroke keys or tactile keys. However, with the narrowing of the stroke or the use of touch input, it is difficult for the user to feel the feedback of pressing, so that the user cannot confirm whether the pressing operation is completed, causing troubles in operation. [0003] At present, there is a design that uses a vibrator to generate vibrations to provide feedback to the user, but this design usually adds a vibrator to the existing button structure,...

Problems solved by technology

However, such devices that provide vibration feedback usually make the whole device vibrate together, or vibrate a certain surface of the device, which cannot provide independent and local feedback, which is not conducive to operation confirmation

[0004] In addition, since this type of keyboard does not have an effective force transmission path when the user presses it, the lower sensing area is often unable to be effectively triggered due to the lack of pressure.

On the other hand, the induction circuit in the induction area may also be triggered when it should not be triggered due to the addition of the above-mentioned vibrator or other mechanisms, resulting in a wrong trigger signal
