Embodiment 1

[0044] see Figure 4 , the metal wire X supporting structure device of the present invention is different from the device of structure in the past and mainly contains keycap 13, rubber elastic ring 6, has two metal outer link connecting rods 8 and 9, support plate 10 that structure is basically the same.

[0045] Explanation: Since the structure of the membrane switch and the bottom plate is basically the same as the previous ones, it is not shown in the figure.

[0046] join Figure 5 , Here it is the structural representation of the present invention, point a place among the figure is the position of rubber elastic ring, (not drawn). Please compare image 3 (Previous space bar structure).

[0047] see Image 6 , a metal steel wire outer connecting rod 8, a schematic diagram of the general structure and connection relationship of the inner connecting rod 9.

[0048] see Figure 7 , the metal outer connecting rod 8 is formed by connecting two X frames 8a with the connect...

Embodiment 2

[0069] see Figure 17 , this is another connection method of the connecting rod, wherein the connecting rod L81 connects the two X frames 8a together, and also forms the outer connecting rod 8, and the connecting rod L81 connects the two X frames 9a together, forming a Inner connecting rod 9.

[0070] All the other are identical with embodiment 1.

Abstract

The invention relates to a space key for a computer keyboard, which comprises a press key, two X linkage mechanisms, a support plate and an elastic element, wherein the linkage mechanisms are connected between the press key and the support plate and are rigidly connected through two connecting rods for forming an integral linkage mechanism, the connecting rods and two X frame structures 8a simultaneously form an outer connecting rod 8, and the connecting rods and two X frame structures 9a simultaneously form an inner connecting rod 9. Through the mechanism device, the structure is perfectly optimized and is simplified, the stability and the balance performance are improved, and the cost is also greatly saved.

Description

technical field [0001] The present invention relates to a key switch device for performing keystroke operations, and more particularly to a key switch device incorporated in a keyboard as an input device of an electronic device. The invention also relates to a keyboard provided with a plurality of such key switch devices. Background technique [0002] The production of the space bar in the existing notebook computer keyboards has adopted a mode, that is, the key cap is supported by two X-shaped structural frames on the left and right, and a spring washer is used in the middle to jack up the key cap. X-shaped structure such as figure 1 As shown, the device is hinged through the hole on the pivot shaft of the plastic inner frame on the plastic inner frame connecting rod 1 and the central hole on the plastic outer frame connecting rod 2, and the lower hinge shaft of the plastic outer frame and the lower shaft of the plastic inner frame are respectively connected with the metal...
