The utility model will be described in detail below in conjunction with embodiment and accompanying drawing as follows;

As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of notebook computer keyboard button device of the present utility model comprises a key cap 10, an elastic actuating body 20, a first bracket 30, a second Bracket 40, a base 50 and a base plate 60 constitute, wherein keycap 10 is the cap body of square shape, and its top surface and bottom surface respectively form an operation surface 111 and an assembly surface 12, and this assembly surface 12 is provided with Two pivot holes 13 and two slide slots 14 .

The elastic actuating member 20 is disposed under the keycap 10 and between the keycap 10 and the base 50 , and the elastic actuating member 20 is located between the actuating stroke of the keycap 10 .

The first bracket 30 and the second bracket 40 are arranged between the mounting surface 12 of the keycap 10 and the base 50, and the middle parts of the first bracket 30 and the second bracket 40 are provided with corresponding pivot shafts 31 and pivot holes. 41 , a linkage mechanism that enables the two brackets 30 and 40 to be pivotally connected to form a cross. The upper ends on both sides of the first support 30 are respectively provided with a pivot 32, and the upper ends on both sides of the second support 40 are respectively provided with a sliding shaft 42. And slidingly fit in the pivot hole 13 and the slide groove 14 of the keycap 10 , so that the upper ends of the first bracket 30 and the second bracket 40 are connected to the assembly surface 12 of the keycap 10 . The first bracket 30 and the lower ends of the second bracket 40 are respectively provided with a pivot 33 , 43 for pivotally connecting to the base 50 . The pivot 33 of the lower end of at least one support 30 of the present invention protrudes from the outer side wall 34 and the rear side wall (or front side wall) 35 of the support 30, so that the rear side wall 35 of the support 30 is in the pivot 33. Between the ends, an angle 36 that is generally inverted L-shaped is formed.

The base 50 is arranged under the keycap 10, the first bracket 30 and the second bracket 40, and the base 50 is preset with a plurality of perforations 51, 52, and these perforations 51, 52 are connected with the first bracket 30 and the second bracket 40. The lower pivots 33, 43 on both sides correspond to each other. The lower end pivots 33, 43 on both sides of the first bracket 30 and the second bracket 40 are pivotally connected to the preset perforations 51, 52 on the base 50, and a positioning piece 53, 54 is respectively provided above the perforations 51, 52 for use. To limit the upward displacement of the pivots 33, 43. The base 50 is provided with an accommodating space 55 penetrating up and down. The first bracket 30 and the second bracket 40 are located above the accommodating space 55 for accommodating the two brackets 30 and 40 .

The base plate 60 is located below the base 50, and a flexible circuit board 70 is provided between the base plate 60 and the base 50. The flexible circuit board 70 and the base plate 60 are also provided with the first support 30 and the second support 40. The corresponding perforations 71, 61 of the lower pivots 33, 43 on both sides.

When the keycap 10 is guided by the two brackets 30 and 40 to move up and down in parallel, the elastic actuating body 20 below the keycap 10 can touch or leave the flexible circuit board 70 to make the switch ON or OFF. When the keycap 10 moves downward in conjunction with the two brackets 30, 40, the two brackets 30, 40 can sink into the accommodating space 55, so that the thickness of the keycap 10 can be adjusted under the principle that the stroke of the key remains unchanged. Reduce, reduce the overall height of the key, and the accommodating space 55 can provide the function of assembling the first bracket 30 and the second bracket 40 from the bottom of the base 50 .

When the pivots 33 at the lower ends of both sides of the bracket 30 of the utility model are pivotally connected to the perforations 51 of the base 50, most of the volume of the pivots 33 can be sunk in the pivoted perforations 51, so that the buttons as a whole can be The height is greatly reduced. Furthermore, the pivots 33 at the lower ends on both sides of the bracket 30 can provide a stop for upward displacement by means of the positioning pieces 53. When the pivots 33 at the lower ends on both sides of the bracket 30 are displaced downward, the angle 36 of the pivots 33 Can be matched with the inside edge of the perforation 61 of the bottom plate 60, and can slide along the inside edge of the perforation 61, the pivot 33 at the lower ends of the two sides of the bracket 30 can thereby provide a stop function for downward displacement, so that the The support 30 has a good positioning in the direction of the Z axis (up and down). The outer wall 34 of the first bracket 30 can provide the blocking effect of the left and right displacement by the inner side of the positioning piece 53, so as to provide the blocking effect of the left and right displacement, and the included angle 36 of the pivot 33 can be matched with the bottom plate 60 The inner edge of the perforation 61 can also provide a blocking effect for left and right displacement, so that the bracket 30 has a good positioning in the direction of the X axis (left and right), so that the keycap 10 is more stable when it moves up and down Shake left and right. Again, the pivot 33 at the lower end of the bracket 30 can provide a blocking effect for front and rear displacements by means of the positioning piece 53 and the positioning hole 51, so that the bracket 30 has a good positioning in the Y-axis (front and rear) direction, so the bracket 30 is positioned at the Y-axis (front and rear). All three axes can have good positioning, so that the two brackets 30 can be stably pivotally connected to the base 50 .

To sum up, this utility model is a rare new creative product, which is extremely novel and progressive, and fully meets the requirements for a new patent application. Aiyi has filed an application in accordance with the Patent Law. Please check carefully and grant the patent for this case. .
