Embodiment Construction

[0040] Please refer to figure 1 , figure 1 It is an exploded schematic diagram of a button with a lifting support device in the present invention. The key 100 includes a keycap 10 , a lifting support device 30 and a bottom plate 50 . The lifting support device 30 is arranged between the keycap 10 and the bottom plate 50, and can support the keycap 10 along the D direction relative to the bottom plate 50 when pushed by the keycap 10. 1 D. 2 direction to move up and down to maintain the stability of the keycap 10 moving up and down.

[0041] The lifting support device 30 has a first link 31 and a second link 32 . The first connecting rod 31 and the second connecting rod 32 are the same element in the present invention, to simplify the mold and the cost of production, but not limited thereto, the first connecting rod 31 and the second connecting rod 32 can also be two elements of different structures. The keycap 10 has a pair of first keycap grooves 12 and a pair of second ...

Abstract

The invention relates to a lifting support device for a key, the key and a keyboard. The lifting support device comprises a first connection rod and a second connection rod. The first connection rod is provided with a first arm portion and a second arm portion, the first arm portion is provided with a first opening groove, and the second arm portion is provided with a first protrusion portion. The second connection rod is provided with a third arm portion and a fourth arm portion, the third arm portion is provided with a second protrusion portion, and the fourth arm portion is provided with a second opening groove. The second protrusion portion extends along a first direction and abuts against the first opening groove, and the first protrusion portion extends along a second direction and abuts against the second opening groove, so that the first connection rod is connected with the second connection rod and the first direction is opposite to the second direction. When the second protrusion portion abuts against the first opening groove and the first protrusion portion abuts against the second opening groove, the first connection rod and the second connection rod can pivot along a virtual axis, and the first direction and the second direction are vertical to the virtual axis respectively. By means of the design, the structure is simple, the assembly is convenient, machining and assembly complexities are reduced, and the material manufacture cost is decreased.

Description

technical field [0001] The invention relates to an input device, in particular to a lifting support device for a key and a key with the lifting support device. Background technique [0002] As far as the usage habits of current personal computer users are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Moreover, the consumer electronic products in daily life or the large-scale processing equipment used in the industry all need to be provided with a key structure as an input device to operate the above-mentioned electronic products and processing equipment. [0003] A conventional key mainly includes a bottom plate, a keycap, and a lifting support device, wherein the lifting support device is used to connect the bottom plate and the keycap. Since the keycap needs to be able to move up and down stably to provide the function of pressing and triggering the switch, in the prior art, a scissor-type bracket is often ...
