Abstract

The invention relates to a thin word key comprising a base plate, a key cap, a dual-seesaw supporting mechanism, a circuit board, a thin insulating film, and an elastic element. The dual-seesaw supporting mechanism consists of a left wing and a right wing, wherein the two wings are hinged to each other by a hinge set; the left wing is pivoted to the base plate and is arranged at the key cap in a sliding mode; and the right wing is pivoted to the base plate and the key cap. The hinge set has a plurality of hinge holes and a plurality of hinge pins, wherein the hinge holes and the hinge pins are arranged at the left hinging segment of the left wing and the right hinging segment of the right wing; and each hinge pin is arranged in each hinge hole, so that the left hinging segment and the right hinging segment can be lifted or pressed down. The circuit board and the thin insulating film are installed on the base plate in sequence; and the elastic element is installed between the key cap and the thin insulating film. Therefore, pre assembling of the dual-seesaw supporting mechanism can be realized, thereby improving the assembling efficiency and reducing the damage rate.

Description

technical field [0001] The invention relates to a key, in particular to a double seesaw support mechanism and a thin key. Background technique [0002] refer to figure 1 and figure 2 , a conventional button 10 includes a base plate 11 , a key cap 12 , a lifting support unit 13 installed between the base plate 11 and the key cap 12 , and two springs 14 . The lifting support unit 13 has two connecting members 15, and each connecting member 15 has two arm parts 151, 152 and a connecting block 153 respectively, which are respectively arranged at two ends of the connecting block 153 and are slidably installed on the bottom plate. The two sliding shafts 154 of 11 are respectively arranged on the arm parts 151, 152 and are away from the sliding shaft 154 and are two rotating shafts 155 rotatably installed on the keycap 12, and are respectively arranged on the arm parts 151 and 152. One tooth piece 156 and two tooth pieces 157 of parts 151, 152. When the assembly is completed, ...
