Description

A kind of foot-operated data collector

Technical field

The utility model relates to computer peripheral.

Background technology

Mouse has been the significant data harvester of operating computer, but just is sought after the data collector that a kind of energy substitutes mouse for the people of both arms deformity; Than the equipment of the complicated control of hyperchannel, only unable to do what one wishes a bit by the two-hand control meeting.

At on September 17th, 2003 bulletin, notification number is that CN2574111Y, name are called in the patent document of " the special-purpose mouse of disabled person ", at on June 13rd, 2007 bulletin, notification number is that CN2911783Y, name are called in the patent document of " foot control mouse ", at on October 3rd, 2007 bulletin, notification number is that CN200956155Y, name are called in the patent document of " split type ground mouse device ", all introduces and disclose foot-operated data collector.

The control pedal of electric sewer also is a kind ofly can liberate the foot-operated simple control device of both hands, by the Internet only retrieve on October 13rd, 2004 bulletin, notification number be that CN2647890Y, name are called the patent document of " a kind of novel sewing machine control pedal ".

There are problems such as practicality is relatively poor, control function is low in above-mentioned several foot-operated data collector.

The utility model content

The technical problems to be solved in the utility model is for the people of both arms deformity and needs the equipment of the complicated control of hyperchannel that a kind of foot-operated data collector is provided.

For solving the problems of the technologies described above the technical scheme that the utility model adopts be: the utlity model has pedal and can detect the sensor of pedal and the variation of negative angle, baffle plate is touched in both sides at pedal, touches baffle plate and directly or indirectly pin is passed to microswitch to the shake-up of touching baffle plate.

Adopt the beneficial effect of above-mentioned foot-operated data collector to be: to open up a new man-machine interaction passage, a people can have been operated more control comparatively complex apparatus, the people of both arms deformity also can have been had ready conditions use a computer.

Annotate: be the structure that gives top priority to what is the most important, omitted among Fig. 3: spring 7, sector rack 13; Be clear display, 17 amplifications of fan-shaped encoding board are drawn among Fig. 6, and it hangs down partial binary coded graphics of four, and actual graphical is finer and closely woven than this.

Embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, pedal 1 among the utility model embodiment is hinged on the base plate 8 by

axle

6,4 rubber blankets 10 are arranged below the base plate 8, there is spring 7 to support between base plate 8 and the pedal 1, pedal 1 has pin holder 5 near an end of axle 6, there is a pair of baffle plate 2 that touches the both sides of pedal 1, an end that touches baffle plate 2 has the axle vertical with pedal 1, be fixed with depression bar 4 on the axle of pedal 1, the most end of depression bar 4 has reset tension spring, depression bar 4 contacts with the button of microswitch 3, and pin passes to microswitch 3 to touching touching through depression bar 4 of baffle plate 2, controls two switching values.

Also be fixed with sector rack 13 on the pedal 1 among the utility model embodiment, sector rack 13 cooperates with gear 12 transmissions on being fixed on potentiometer 11, potentiometer 11 is fixed on the support 9, support 9 is fixed on the base plate 8, the angle of pedal 1 and base plate 8 is because of different change of the dynamics of trampling of pin, pedal 1 passes to potentiometer 11 with the variable angle of base plate 8 through sector rack 13, gear 12, changes the position of potentiometer 11 travelling arms, obtains an analog quantity.
