Abstract
The utility model provides an improved keyboard of a portable computer. The improved keyboard of a portable computer comprises a host computer bottom seat and a keyboard, wherein, the host computer bottom seat is provided with a supporting mechanism. The supporting mechanism is composed of a screw rod, two screw guiding blocks and back end pivoted supporting rods, wherein, the screw rod is arranged on the host computer bottom seat. The screw rod extending toward the two sides is provided with two inverse screw thread parts, and the two screw guiding blocks are respectively screwed on the two end screw thread parts of the screw rod. The front end parts of the two supporting rods are respectively pivoted on the two screw guiding blocks. The keyboard is divided into two separated parts, and the two separated parts of the keyboard are respectively fixed on the two supporting rods. The improved keyboard of a portable computer tilts forwardly with an angle when the keyboard is automatically divided into two side zones. Therefore, an operating staff can feel more natural and comfortable when the improved keyboard of a portable computer is used.
Description
The utility model relates to a kind of improvement keyboard of portable computer.
The improvement keyboard of existing portable computer all is to be horizontally set on the computer body, and the layout employing level and the vertical interlaced of each button are distributed in form.Because operating personnel are when using this computer, elbow portion outwards stretches naturally, and therefore pushing direction and generally a degree of tilt should being arranged of palm and finger when using this keyboard, often have sense of discomfort, and influence use.And the improvement keyboard of portable computer is generally narrow than common computor-keyboard, and is just more inconvenient when operation like this.
The purpose of this utility model just provides a kind of improvement keyboard of portable computer, and it can make keyboard have stable degree of tilt, and can make integral keyboard fork branch expand into two lateral areas, so that keyboard uses the requirement that more meets human performance.
The purpose of this utility model is achieved in that a kind of improvement keyboard of portable computer, it comprises host computer base and keyboard, wherein the base of main frame is provided with supporting mechanism, supporting mechanism articulates strut by a screw rod, two spiral guide blocks and rear end and forms, wherein screw rod is located on the main frame base, screw rod is provided with the reverse threaded portion of two-phase to the extension of two sides, and rotation set is on the threaded portion, two ends of screw rod respectively for two spiral guide blocks, and the leading section of two struts then is articulated in respectively on the two spiral guide blocks; Keyboard is divided into two separated portions, is separately fixed on two struts.
The spacing of screw flight greater than keyboard weight be added in strut the moment to producing on the spiral guide block.
According to the technique scheme analysis as can be known, the utility model meets the requirement of human engineering, and its angle of steeving that turns forward when keyboard is divided into two lateral areas is automatically more felt nature, comfortable when operating personnel use.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Inner structure action synoptic diagram when Fig. 2 folds for keyboard of the present utility model;
Fig. 3 is the overall appearance synoptic diagram after of the present utility model the folding;
Fig. 4 separates schematic appearance for keyboard of the present utility model.
Referring to Fig. 1, be structural representation of the present utility model.Mainly comprise host computer base 1 and keyboard 2, wherein main frame base 1 one sides articulate video screen 11,2 on keyboard prolongs cut-off rule 23 and is divided into first keyboard region 21 and second keyboard region 22, and pivot center 24 is set in the rear end of above-mentioned cut-off rule 23, supporting mechanism 3 is by a screw rod 31, two spiral guide blocks 32,33 and the rear end articulate strut 34,35 form, wherein screw rod 31 is located on the main frame base 1, screw rod is provided with the reverse threaded portion of two-phase 311 to the extension of two sides, 312, two spiral guide blocks 32,33 difference rotation sets are in the threaded portion, two ends 311 of screw rod, on 312, two struts 34,35 respectively with two keyboards 21,22 bottom surface Joints, two struts 34,35 trailing edge articulates above-mentioned pivot center 24, preceding termination spiral guide block 32,33.
Referring to Fig. 2,3,4, when first keyboard 21 and the 22 mutual closings of second keyboard folded, its spiral guide block 32,33 was mutual closing contact, and two struts 34,35 keep minimum angle.When first keyboard 21, second keyboard 22 is pulled and separately the time, spiral guide block 32,33 slides to screw rod 31 both side ends respectively, be subjected to the effect of threaded portion 311,312 that spiral guide block 32,33 is rotated on screw rod 31 in the same way, then rise in the pivot center 24 that is connected mutually of two struts 34,35 thereupon, first keyboard 21 on the strut 34,35 and second keyboard 22 form an angle of inclination, make two keyboards 21,22 except that the front side pivot launches, steeve forward, produce the angle that meets the human efficiency.
The spacing of screw rod 31 screw threads is added in 34,35 moments to producing on the spiral guide block 32,33 of strut greater than keyboard 21,22 weight, to prevent that keyboard 21,22 weight owing to self from making strut 34,35 promote 32, the 33 inside slippages of spiral guide block and folding.
