Abstract

The utility model discloses a cylindrical mouse. The cylindrical mouse is characterized by comprising a cylinder (1), an angle sensor (2), a single-chip microcomputer (3), an EM84502AP chip, a standard key (4) and a key device, the angle sensor (2) and the single-chip microcomputer (3) are arranged on the cylinder (1), the EM84502AP chip is connected to a computer, the key device is installed on the cylinder (1) and used for achieving the left key function of the mouse, the EM84502AP chip, the standard key (4) and the angle sensor (2) are connected to the single-chip microcomputer (3), and the key device is connected to the EM84502AP chip. During using, the cylinder (1) is vertically placed on a table, the standard key (4) is pressed down, the mouse cursor position is initialized, then the cylinder (1) is held by hand to be moved forwards, backwards, leftwards and rightwards to enable the angle sensor (2) to detect the position change, the position change is converted into an analog signal to be input into the single-chip microcomputer (3) to be processed, the single-chip microcomputer (3) analyzes the signal and controls corresponding movement of the cursor, and then the mouse clicking function can be finished by triggering the key device.

Description

A kind of pillar mouse

Technical field

The utility model patent relates to a kind of computer entry device, is specifically related to a kind of mouse.

Background technology

In recent years, the popularity rate of China's computer improved rapidly, and in people's daily life work, computer has almost become necessity, and according to incompletely statistics, by the end of in Dec, 2013, China netizen number has broken through 6.18 hundred million.But use for a long time computer, repeating rolling mouse, wrist joint repeatedly, excessive activity, will cause peripheral nerve injury or suffer oppression, even cause hypoxic-ischemic and occur numb grade for series of symptoms.And in those life and works, be unable to do without the netizen of computer, excessive use computer also just means the formation of their mouse hand.

Summary of the invention

The utility model, in order to overcome the deficiency of above technology, provides a kind of pillar mouse.

The utility model overcomes the technical scheme that its technical matters adopts.

This pillar mouse, comprises cylinder; Be installed on angular transducer, the single-chip microcomputer on cylinder, the EM84502AP chip that is connected in computer, benchmark button; Be installed on cylinder for realizing the key device of left mouse button function, described EM84502AP chip, benchmark button and angular transducer are connected in single-chip microcomputer, described key device is connected in EM84502AP chip.

Above-mentioned key device is cylinder end face, the mousebutton that can touch with thumb while holding cylinder.

Adjust for the convenience of the users mouse pointer translational speed, also comprise the turbo and the deceleration button that are installed on cylinder and are connected in single-chip microcomputer.

Above-mentioned angular transducer is MMA7361 type angular transducer.

Above-mentioned single-chip microcomputer is STM32F104RB type single-chip microcomputer.

The beneficial effects of the utility model are: when use, cylinder is vertically placed on desk, press benchmark button, make mouse cursor position initialization, can all around move and make angular transducer change in displacement be detected and change simulating signal into input to single-chip microcomputer processing by holding cylinder afterwards, single-chip microcomputer carries out signal after analyzing and processing, input four road PWM ripples to EM84502AP chip, chip can be exported data to computer by data line after receiving signal, move accordingly thereby control cursor, can complete mouse click function by touching key device afterwards.Therefore by this pillar mouse, can complete the operation to computing machine aloft, solve the problem of long-time use computer formation mouse hand.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is control system square frame principle schematic diagram of the present utility model.

In figure, 1. cylinder 2. angular transducer 3. single-chip microcomputer 4. benchmark button 5. turbo 6. deceleration button 7. mousebuttons.

Specific embodiments

Below in conjunction with accompanying drawing 1, accompanying drawing 2, the utility model is described further.

This pillar mouse, comprises cylinder 1; Be installed on angular transducer 2, the single-chip microcomputer 3 on cylinder 1, the EM84502AP chip that is connected in computer, benchmark button 4; Be installed on cylinder 1 for realizing the key device of left mouse button function, described EM84502AP chip, benchmark button 4 and angular transducer 2 are connected in single-chip microcomputer 3, described key device is connected in EM84502AP chip.When use, cylinder 1 is vertically placed on desk, press benchmark button 4, make mouse cursor position initialization, afterwards can by holding, cylinder 1 is mobile all around to be made angular transducer 2 change in displacement be detected and changes simulating signal into input to single-chip microcomputer 3 and process, single-chip microcomputer 3 carries out signal after analyzing and processing, input four road PWM ripples to EM84502AP chip, chip can be exported data to computer by data line after receiving signal, move accordingly thereby control cursor, can complete mouse click function by touching key device afterwards.Therefore by this pillar mouse, can complete the operation to computing machine aloft, solve the problem of long-time use computer formation mouse hand.

Above-mentioned key device is cylinder 1 end face, while holding cylinder, can touch mousebutton 7 with thumb.When user holds after cylinder 1, thumb is placed on to mousebutton 7 places gently, need only afterwards the thumb lower mousebutton 7 of pressing gently, just can produce a high pulse signal, signal pulse is sent to EM84502AP chip by single-chip microcomputer 3, the signal that EM84502AP chip produces sends computer to by data line, realizes cursor and click function after computer deal with data.

Also comprise the turbo 5 and the deceleration button 6 that are installed on cylinder 1 and are connected in single-chip microcomputer 3.Can adjust the output PWM wave frequency of single-chip microcomputer 3 by turbo 5 and deceleration button 6, thereby realize the adjustment of mouse pointer translational speed speed.With person easy to use according to practical situation adjustment.
