Description
Technical field
The present invention relates to a kind of optical mouse that is used on computing machine and the electronic equipment, relate in particular to a kind of optical mouse of built-in mouse pad.
Background technology
Since Douglas Engelbart had invented computer mouse (as United States Patent (USP) the 3rd, 541, shown in No. 541), great change had taken place in the computer mouse that is used for the personal computer navigation.Mouse has become one of basic outfit of computer peripheral.As the hinge between people and the computer, as long as the user allows mouse move along with the position of palm, indiscriminately ad. as one wishes the position of the mouse pointer in the controlling computer display screen clicks as simple key-press with finger tip simultaneously, just can finish the input of instruction, so that the computer executable operations.
At present, be used for the various mouses on computing machine and the electronic equipment, volume is small and exquisite, and most in shape and human body hand-type adapts, and promptly roughly is bottom level, the pattern design of arching upward in the back.In use, operator's wrist joint generally is against on the desktop, and palm is then prostrate at the back of mouse, and roughly matches with the back, and each is distributed in finger on the back of mouse with regard to it.Like this, operator's wrist is the trend that is bent upwards, and its wrist is understood the bigger pressure that bears of nature, and is especially more outstanding when mouse is mobile in the plane.So long-term use, will damage the muscle and the passages through which vital energy circulates of hand, also can cause operator's arm to be ached, even become the mouse hand because of the tendon inflammation with weak, not only influence the user in the future for the use of mouse, more bring great difficulty with life healthy.
Existing mouse mainly comprises two kinds of electromechanical mice and optical mouse.Optical mouse is mostly on the basis of original electromechanical mice, adopts optical positioning system to replace dynamo-electric positioning system.Because its accurate positioning, sensitivity is good, moves smooth and is difficult for characteristics such as stolen goods dirt, be subjected to approving widely and replacement gradually electromechanical mice.Optical mouse is usually by forming with the lower part: optical sensor, optical lens, light emitting diode, interface microprocessor, soft-touch type button, roller, line, PS/2 or USB interface, shell etc.The principle of work of optical mouse is: a light emitting diode is arranged in optical mouse inside, by the light that this light emitting diode sends, illuminate optical mouse lower surface (Here it is why the always luminous reason in mouse bottom).With a part of light of optical mouse lower surface reflected back,, be transferred to the interior imaging of a photoinduction device (little imager) then through one group of optical lens.Like this, when optical mouse moved, its motion track just can be registered as the coherent image of one group of high-speed capture.Utilize a special image analysis chip (DSP of optical mouse inside at last, be digital microprocessor) a series of images that absorbs on the motion track is carried out analyzing and processing, by the variation of characteristic point position on these images is analyzed, judge mouse moving direction and displacement, thereby finish the location of cursor.Because the special tectonic of optical mouse, it is bigger to be equipped with a surface area in the bottom in use, the mouse pad of quality even roughness.This has increased user's fund input undoubtedly again.Because mouse is when work, the bottom often rubs with mouse pad, mouse pad upper surface wearing and tearing of long duration are very serious, because its long term exposure is in air, contact with skin, mouse bottom, airborne dust, moisture etc., aging easily, be out of shape dirty, reduce the degree of accuracy of mouse location, shortened its serviceable life.During mouse performance, need move on working face, mouse pad is for cooperating this requirement, so done very greatly, extremely be not easy to carry, occupied a large amount of valuable desk-top space resources simultaneously, for very unfavorable the working clan of special place work such as office building.Some people does not even use mouse pad, directly allows mouse operate on smooth desktop, and this greatly reduces the performance of optical mouse undoubtedly again.
This shows that above-mentioned existing mouse obviously still exists inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that mouse has, relevant manufacturer and professional person there's no one who doesn't or isn't seek solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
Summary of the invention
The objective of the invention is to, overcome the defective that existing mouse exists in use, and a kind of new structure optical mouse of built-in mouse pad is provided.It can effectively avoid the long-time finger of back generation and the fatigue of wrist used to ache, and operates more smoothly, and comfortable, hommization more is convenient for carrying.
The object of the invention to solve the technical problems realizes by the following technical solutions.The optical mouse of this built-in mouse pad includes optical positioning system and button.It is characterized in that: the planar mouse pad of routine is designed to the sphere arcuate structure, and is built in the mouse case, link to each other with mouse top shell by connecting link.
When needing moving cursor, user's middle finger is pinned mouse center of top button rolling mouse top shell simultaneously, and mouse top shell drives built-in mouse pad by connecting link and moves.Reset for ease of mouse top shell and built-in mouse pad, the edge of built-in mouse pad is provided with a coil spring with symmetric mode, and the other end of this spring is connected the bottom of mouse base internal layer.Like this, when a certain direction moved, the spring opposite with this direction will be stretched at mouse pad, thereby made mouse pad have the reset trend opposite with this direction with the top shell that links to each other.
Theoretically, the spring that is arranged between mouse pad and the base is The more the better, but because the restriction of mouse base space size, simultaneously for ease of producing, reduce production costs, and can guarantee that mouse pad when all directions activity, all has the trend that resets of the middle position that playbacks, described spring serves as that the boundary angle is evenly distributed four all around for good at the mouse pad edge with 90 °.In actual production, may use stiffness spring silk or other reseting performance better material, in this not narration one by one.
According to the optical alignment principle, the light source in the optical positioning system must produce diffuse reflection on reflecting surface, just can obtain the video of sampling preferably.Therefore, the reflective concave surface of built-in mouse pad is the uniform uneven surface of a surface pattern, rather than smooth curved surface.
For preventing that impurity such as dust from entering mouse inside, dirty optical positioning system and miscellaneous part, simultaneously to pursue all many-sided requirements such as practical and attractive, be provided with a circular arcuation high resiliency polyester fiber film above the connecting link between this mouse top shell and the built-in mouse pad, the edge of film links to each other with base upper strata inside surface.Whole mouse internal mechanical element protection is got up.Membrane middle layer is a spiral round lead spring, and the electronic component on shell top, top is linked to each other with the bottom Circuits System, carries out data transmission.The lead that connects the bottom internal circuit is then drawn by the metallic channel in the base shell, and lead and metallic channel are not done special description at this.Because the performance of lead spring self plays the auxiliary reset effect, it is more accurate that top shell and mouse pad are resetted.
In mouse bottom and shell outside, top, serve as that the boundary even angle is provided with three buttons with 54 ° of angles, be respectively ceiling button, top girdle shape button, base annular button.Ceiling button has two key journeys, similar in appearance to the shutter key of digital camera, pins half expression cursor of mouse displacement confirmation signal, and by the page turning confirmation signal of representing document or webpage on earth, when unclamping, then the bottom shaven head does not read any data.
Top girdle shape button and base annular button is then similar in appearance to the left button and the right button of ordinary optical mouse.Because with reference to the ergonomics design parameter, reach the golden section law as height ratio when design, angle is 54 ° of angles that are evenly distributed.Whole button is an annular design, and the key table area is roomy, each button evagination, and surperficial rounding off also is streamlined, is fit to finger manipulation more.
The optical positioning system of the optical mouse of this built-in mouse pad and common mouse are approximate, comprise optical sensor, optical lens, light emitting diode, interface microprocessor, soft-touch type button etc.The principle of work of its principle of work and ordinary optical mouse is basic identical, just by original emit beam to change into to the optical mouse bottom to the built-in mouse pad of the arc at optical sensor top emit beam, through one group of optical lens, be transferred to the interior imaging of a photoinduction device (little imager) again.Like this, when built-in mouse moved, its motion track just can be registered as the coherent image of one group of high-speed capture.Utilize a special image analysis chip (DSP of optical mouse inside at last, be digital microprocessor) a series of images that absorbs on the motion track is carried out analyzing and processing, by the variation of characteristic point position on these images is analyzed, judge mouse moving direction and displacement, thereby finish the location of cursor.The signal of cursor positioning can pass through line, PS/2 or USB interface are transferred in the computer, perhaps pass through the wireless launcher of mouse inside, be sent to be connected with form of electromagnetic wave and arrive receiver on the computer interface, and finally on display screen, form cursor displacement and other various operations.
The roller devices of ordinary optical mouse is omitted in this invention, but its specific function do not omit, but finish by the array configuration of other keys.Pressing the center of top button on earth the time, the trajectory signal of internal optics positioning system is automatically converted to the page turning positioning signal.The rolling mouse top cover drives built-in mouse pad and moves, and can finish just that webpage drags or the document page turning, makes optical positioning system be fully utilized, and has omitted this device of roller simultaneously again, saves cost, is to kill two birds with one stone.
Because this mouse bottom is provided with the ring-shaped rubber sucker, makes this mouse to stablize and places any plane that the inclination angle is arranged, floor area is little simultaneously, and practicality and convenience are very outstanding.
Compared with prior art, the invention has the advantages that: the mouse pad that optical alignment is needed is designed to arc and is built in the mouse, drives moving of built-in mouse pad by palm and the mobile top of finger shell, forms relative displacement.Optical positioning system is realized cursor positioning by reading displacement signal.Its brand-new key operation and simulation roller operation have changed the mode of operation that move on ordinary optical mouse plane, can effectively avoid the finger and the wrist fatigue symptom that cause because of long-time operation, and be more comfortable, hommization more.The present invention has large improvement technically, is suitable for practicality more, and product structure is simple, is easy to produce assembling, has the extensive value of industry, is the new design of a novelty, progress, use in fact.
