Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0022] see figure 1 The disclosed schematic diagram of the assembly structure of the keyboard of the present invention, the keyboard adopts capacitive touch sensing technology to realize the collection of key operation signals, the principle and specific implementation plan of capacitive touch sensing technology are mostly seen in the prior art, and because of the present invention It mainly involves the improvement of the button structure, so the specific implementation of the capacitive touch sensing technology will not be described in detail.

[0023] Structurally, as figure 1 As shown, the keyboard of the present invention includes a base plate 1 , a double-sided adhesive tape 2 , a capacitive sensing plate 3 and a key cover 4 . The bottom plate 1 serves as a supporting element of the entire keyboard, mainly for structural support and packaging, and acc...

Abstract

The invention discloses a force feedback type capacitance touch key structure and a keyboard with the same. The key structure comprises a base board, a capacitive sensing board and keycaps, wherein the capacitive sensing board is laid on the base board, the keyboards are arranged on the capacitive sensing board, a capacitance cell for detecting touch operations of the keycaps by users is arranged at a position corresponding to the positions of the keycaps on the capacitive sensing board, interlayer space is formed between the keycaps and the capacitive sensing board, and at least one block-shaped elastic element is placed in the interlayer space, deviates from the peripheries of the keycaps, and is used for supplying reactive force for external acting force towards the capacitance unit caused by touch operations of the keycaps. The key structure is suitable for being used in the whole keyboard, the key structure can be adopted on parts or each key in the keyboard, the keyboard with the structure has obvious force feedback effect during key pressing, and rapid and accurate key pressing operations by users are facilitated.

Description

【Technical field】 [0001] The invention relates to a structure of a force feedback capacitive touch button and a keyboard adopting the structure. 【Background technique】 [0002] In traditional computer keyboards, key operation is usually achieved by using a lifting structure with keys and conductive contacts. The elastic structure inside the conductive contacts can provide a reaction force for the keycap, thereby providing a force for the finger pressing on the keycap. A segmented force feedback to enhance the user's perception of the button touch. This type of button realized by the key lifting structure is mostly seen in the prior art. The earliest key lifting structure is summarized as a scissors structure by those skilled in the art. Later, the applicant once found another way to provide a double-opening structure. For details, please refer to the CN101783257A patent announcement. This traditional keyboard adopts many key lifting structural components, and the volume is...
