Problems solved by technology

[0003] If the pressing direction of the button is not in the same direction as the printed circuit board of the management chip, then it is necessary to make another button board to realize the button function, and then connect the button board back to the printed circuit board through wires. This structure needs to be made separately. The button board has a great demand for space, and at the same time increases the instability of the structure. The boards need to be connected by welding or connectors, which increases the preparation cost

Embodiment Construction

[0029] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0030] Embodiments of the present invention provide a key structure suitable for long strokes. The key structure occupies less space and is more suitable for input devices with limited space. At the same time, the key structure utilizes long strokes to ensure the feel of the key.

[0031] For a button structure that requires a higher button feel, the stroke of the button is longer. Here, the stroke of the button refers to the distance traveled by the button when a button is pressed. If you feel the ups and downs of the keys are more obvious when you hit the keys, it means ...

Abstract

The invention discloses a key structure and input equipment suitable for long stroke. The key structure comprises a key, a long stroke control member, a first pasting layer, a flexible flat cable, a second pasting layer and a baffle plate in sequence, wherein the long stroke control member is pushed to move under an external force effect so that the key is in contact with the flexible flat cable, electric conduction between the long stroke control member and the flexible flat cable is triggered to generate a key signal; the long stroke control member and the flexible flat cable are adhered and fixed together through the first pasting layer, and the flexible flat cable and the baffle plate are adhered and fixed together through the second pasting layer.

Description

technical field [0001] The invention relates to key technology, in particular to a key structure suitable for long strokes and an input device. Background technique [0002] In order to ensure the tactile feel of the keys, the current input devices adopt a structure of physical keys and long-travel rubber pads. Among them, the graphite conductive silica gel is pasted inside the rubber pad, and the copper on the printed circuit board is connected through the graphite conductive silica gel, so as to conduct the circuit and realize the button function. [0003] If the pressing direction of the button is not in the same direction as the printed circuit board of the management chip, then it is necessary to make another button board to realize the button function, and then connect the button board back to the printed circuit board through wires. This structure needs to be made separately. The key board requires a great deal of space, and at the same time increases the instability...
