Embodiment
As shown in Figure 1-Figure 3, the utility model
Mouse roller 6 and mouse roller support 3 form roller device of mouse jointly; Roller device of mouse is fixed on below fixed head 5.A hand arteries and veins signal plug socket 2 is provided with between two, the side copper post of mouse roller.
Fixed head is provided with the tie-hole 9 that 6 diameters are 4mm.Utilize self-locking nylon cable tie roller device of mouse can be fastened on fixed head 5; Fixing means is: the tie-hole of a self-locking nylon cable tie from mouse roller 6 opposite side passed, walk around mouse roller support 3, then wear from the tie-hole of symmetrical side, finally self-locking nylon cable tie is locked, complete the fixing of mouse roller support side; Fixing of opposite side, fixes with another root self-locking nylon cable tie, same as above.
Roller device of mouse each side have two copper posts 4, all utilize holding screw 8 to be fixed on fixed head 5 by four of roller device of mouse copper posts.
Roller device of mouse and fixed head 5 form hand arteries and veins unit, and hand arteries and veins unit is fixed on (concrete fixed form is: use holding screw 8 to be fixed on user's motherboard 1 by the other end of copper post) on motherboard 1.
Be provided with grating disc in mouse roller 6, grating disc sends three signal wires and is all welded on fixed head 5.
Coupled together by hand arteries and veins signal plug socket 2 between fixed head 5 and motherboard 1.
Pulse electrical signal is produced by mouse roller, and when operating personnel operate, first handy finger roll mouse roller, drive the grating disc of its inside to rotate, then mouse roller could export pulse signal A and the pulse signal B of 90 degree of phase differential.Signal output type due to pulse signal A and B of mouse roller is that OC door exports, so pulse signal A and B, have to pass through pull-up resistor R1 and R2 and change vacant state into stable high level state, such pulse signal A and B just can export: the pulse signal of high level to be 5V low level be OV.Pulse signal A and B is through a RC filtering circuit subsequently, and RC filtered electrical routing resistance R3 and electric capacity C1 forms, and effect is filtered out the clutter in pulse signal A and B and high frequency waves, to improve the anti-interference of whole circuit.Corner frequency f=1/2 π R3C1, the product of resistance R3 and electric capacity C1 is larger, and filter effect is better.Final pulse signal A and B is admitted to orthogonal encoder interface P1-20 and P1-23 of 32 8-digit microcontrollers (LPC1788).
The microcontroller of LPC1788 to be a with Cortex-M3 be kernel, with orthogonal encoder interface, can monitor an outside orthogonal encoder.And pulse signal A and B in Fig. 3 is exactly pair of orthogonal signal.Such pulse signal A and B just can calculate the position of hand arteries and veins, and determine the direction that hand arteries and veins rotates after sending into LPC1788 orthogonal encoder interface.
Mouse roller:
Material is high-quality synthesized silicon rubber, and this elastic properties of materials is good, soft, and when operative's hand arteries and veins, first handy this mouse roller of finger roll, drive the grating disc of its inside to rotate, then mouse roller could export the pulse signal of positional information.Pulse signal just can complete the process of final hand arteries and veins positional information after sending into microcontroller.
The support of mouse roller:
Effect supports mouse roller, can allow the rotation that mouse roller is stable, have and significantly rotate feel, the material of the support of mouse roller is ABS plastic, this material has outstanding physical characteristics and thermal behavior, has higher intensity, which improves the durability of mouse roller.
