By the optomagnetic 3D mouse apparatus structure of a kind of six degree of freedom of the utility model vertical view Fig. 2, structure upward view Fig. 3 and side sectional view Fig. 4 as can be known, the utility model has increased by 1 LED lamp, 1 catoptron group, 1 spherical mirror, 1 image-position sensor, 4 magnet, 4 pressure transducers on traditional optical mouse basis, wherein, LED lamp, catoptron group, spherical mirror cooperate distance that image-position sensor measurements move horizontally and around Z axle rotation amount, magnet cooperate pressure transducer measure the vertical range of rising, around the X-axis rotation amount with around the Y-axis rotation amount.
Be further detailed below by the optomagnetic 3D mouse device of a kind of six degree of freedom of the utility model of embodiment.
Be the optomagnetic 3D mouse device of a kind of six degree of freedom of the utility model light path schematic configuration diagram as shown in Figure 5.
As shown in Figure 5, when mouse rises, catoptron group 2021 reflexes to the mouse bottom with the light of LED lamp 2011 emissions, light converges on the image-position sensor 2041 through spherical mirror 2031, one group of image that image-position sensor 2041 will be taken is transferred to chip 205, in like manner the image-position sensor 2042 of opposite side also is transferred to chip 205 with the image that LED lamp 2012 reflection rays irradiate, chip goes out two horizontal shifts according to the graphical analysis of two image-position sensor transmission, the mean value of getting two horizontal shifts is exactly the horizontal shift that six-freedom degree mouse moves, at this moment pressure transducer 2061 is subjected to the acting force between magnet 2071 and the optomagnetic dual-purpose mouse pad 209, in like manner pressure transducer 2062,2063,2064 also can be subjected to magnet 2072,2073,2074 and optomagnetic dual-purpose mouse pad 209 between acting force, chip is according to the variable in distance on the signal analysis vertical direction of four pressure transducers transmission (namely four pressure transducers analyze out the mean value of the vertical range that changes).
Be the optomagnetic 3D mouse device of a kind of six degree of freedom of the utility model application scenarios first embodiment schematic configuration diagram as shown in Figure 6.
As shown in Figure 6, when mouse when X-axis is rotated, great changes will take place with pressure differential that X-axis pressure at right angle sensor 2072,2074 is subjected to, and at this moment the fixed range that outes between pressure differential and the pressure transducer 2072,2074 of the chip calculated signals of coming in according to pressure transducer 2072,2074 transmission calculates six-freedom degree mouse around the rotation amount of X.In like manner, when mouse when Y-axis is rotated, chip can be calculated rotation amount around Y according to the pressure difference meter that pressure transducer 2071,2073 is subjected to.
Be the optomagnetic 3D mouse device of a kind of six degree of freedom of the utility model application scenarios second embodiment schematic configuration diagram as shown in Figure 7.
As shown in Figure 7, when mouse when the Z axle rotates, be focused at 2041,2042 image through the light of catoptron group 2021,2022 through spherical mirror bigger difference can take place, chip calculates rotation amount around the Z axle according to the fixed range between two image-position sensor image transmitted and the spherical mirror 2041,2042.
Wherein, be in catenary motion state or rotation status in order to tell mouse, the mouse plug-in judges that the pressure differential of pressure transducer is about 1N, and pressure differential is greater than the rotation status that is in of 1N, otherwise is in mouse catenary motion state.
By the utility model light path schematic configuration diagram Fig. 5, embodiment schematic configuration diagram Fig. 6 and Fig. 7 are as can be known, the utility model adopts and the similar method of conventional two-dimensional optical mouse is measured the displacement of horizontal X Y both direction, the two dimensional image that collects according to image-position sensor before and after mouse moves carries out analysis meter and calculates displacement on the both direction, be transferred to computer then, difference is catoptron group 2021,2022 make the incident angle of the relative mouse pad of emergent ray smaller through reequiping (less than 30 degree), and the relative conventional mouse of the size of spherical mirror and image-position sensor increases to some extent, be under the differing heights situation at mouse guaranteeing, the reflection ray of mouse pad still can be collected by spherical mirror and image-position sensor, and is used for the horizontal level of computing mouse.In more detail, the traditional relatively optical mouse measuring method of present embodiment measuring method on horizontal X Y both direction improves to some extent, horizontal survey principle after the improvement further specifies as follows: smaller to the incident angle of the light of mouse pad 209 through mirror reflects in the mouse, mouse leave optomagnetic dual-purpose mouse pad 209 surfaces certain vertical apart from the time, light still can reflex to spherical mirror 2031,2032 and imaging on image- position sensor 2041,2042, and the displacement by chip 205 calculated level directions.And the relative mouse of conventional two-dimensional optical mouse emergent ray is lined with bigger incident angle, the conventional two-dimensional mouse just leaves desktop or the very little vertical distance of mouse pad because light is reflected to mouse the place ahead, and can't reflex on the spherical mirror 103 and be imaged onto image-position sensor 104.Wherein, the mouse that incident angle is operated according to three dimensions leaves mouse pad 208 vertical maximum distances and makes amendment, such as, when mouse is 10 centimetres apart from the mouse pad maximum distance, and incident angle is about 5 degree, like this, position and outgoing position that reflected light is got back to the mouse bottom only differ about 1.75cm farthest, because the centre distance of eye point and spherical mirror is 1.7cm in the present embodiment, and the radius of spherical mirror is 1cm, reflect therefore that luminous energy is assembled by spherical mirror and by the image-position sensor imaging.
Be the optomagnetic 3D mouse device of a kind of six degree of freedom of the utility model workflow diagram as shown in Figure 8.
As shown in Figure 8, when mouse rises, the pressure that four pressure transducers are subjected to changes simultaneously, chip calculates four distances respectively according to the signal of four pressure transducer transmission, the average distance that is exactly mouse on the optomagnetic mouse pad vertical direction, mouse is made corresponding reaction according to the distance of chip transmission.When mouse moves horizontally, two groups of images that chip photographs according to two image-position sensors analyze the distance of two directions Xs on the two-dimensional directional and the distance of two Y-directions respectively, and averaging respectively is exactly directions X distance and the Y-direction distance that mouse moves in the horizontal direction.When mouse during around the rotation of X-axis or Y-axis, great changes will take place for the pressure that two pressure transducers vertical with X-axis or Y-axis are subjected to, chip calculates rotation amount around X-axis or Y-axis according to the fixed range between the pressure differential of two pressure transducers and two pressure transducers, and mouse transmits the rotation amount control cursor of coming in according to chip makes corresponding reaction at computer screen.When mouse when the Z axle rotates, fixed range between the picture group sheet that chip is taken according to two image-position sensors and two image-position sensors calculates the rotation amount around the Z axle, and mouse transmits the rotation amount control cursor of coming in according to chip makes corresponding reaction at computer screen.
In the present embodiment, vertical Z direction change in location is by built-in magnet 2061,2062,2063,2064 and optomagnetic dual-purpose mouse pad 209 power of having an effect, and converts by pressure transducer 2071,2072,2073,2074 that electric signal detects to.Wherein, when mouse during around the rotation of X-axis or Y-axis, the pressure ratio that two pressure transducers parallel with X-axis or Y-axis are received is fainter, when pressure differential less than 1N, can ignore.
Below the pressure transducer that detects on the Z direction is further detailed.
