Embodiment
As shown in Figure 1, transmission mechanism of the present utility model comprises gear housing 16 and is located at driving-chain on the gear housing, driving-chain has two groups, realize the slip of display screen respectively and turn over the transmission work, on gear box 16, be fixed with 26,27, two motors of two motors and driving-chain thereof and be arranged on gear box 16 both sides; The driving-chain of the slip of realization display screen is by motor 27, worm screw 12, the 7th gear 13, the 6th gear 11, first clutch 7, the 4th gear 8, the 5th gear 10,20, octadentate wheel 14, the 14th gear A 7, potentiometer 15, the tooth bar (not shown) is formed, be connected with first worm screw 12 on 27 in its motor, first worm screw 12 and the 7th gear 13 (helical gear) engaged transmission, establish straight-tooth gear on 13 of the 7th gears, this straight-tooth gear drives the 6th gear 11 and rotates, the 6th gear 11 drives transmission clutch 7 and rotates, clutch 7 drives the 4th gear 8 and rotates, the 4th gear 8 drives the 5th gear 10, (gear box each side has a gear 10 in 10 ' rotation, 10 ', can rotate synchronously), the 5th gear 10,10 ' the rolling (tooth bar is not shown in the figures) on tooth bar, with the 5th gear 10, octadentate wheel the 14 and the 5th gear 10 of 10 ' concentric shafts rotates synchronously, octadentate wheel 14 drives the potentiometer gear and rotates, and the potentiometer gear is inserted in the potentiometer.
Realize that display screen turns over the driving-chain of transmission work by motor 26, second worm screw 17, the 9th gear 18, transmission clutch 19, the 11 gear 21, the tenth gear 20, the 12 gear 22, the 13 gear 23, the 14 gear 24, first sector 25, second sector 2, first gear 3, second gear 4, the 3rd gear 5, potentiometer 6 is formed, motor 26 energisings drive worm screw 17 and rotate, worm screw 17 drives the 9th gear 18 (helical gear) and rotates, in worm screw 17 and the 9th gear 18 shared two groups of driving-chains, the 9th gear 18 drives transmission clutch 19 and rotates, pass motion to the tenth gear 20 later on successively, the 11 gear 21, the 12 gear 22, the 13 gear 23, the 14 gear 24,1 upset of first sector, 25 driving display screen bonnets, in the riveted joint of display screen bonnet 1 opposite side second sector 2 is arranged, when 25 upsets of first sector, partly transfer torque to second sector 2 by display screen, sector 2 can drive first gear 3 and rotate when rotating, drive second gear 4 later on successively, the 3rd gear 5 and potentiometer 6 rotate; Potentiometer gear one end snaps in the semi-circular hole of potentiometer, drives two contacts rotation in the potentiometer.
In above-mentioned two kinds of driving-chains, the terminal gear of slip driving-chain rotating speed after slowing down is higher relatively, and transmission clutch 7 places the driving-chain middle position, apart from gear 10 the two poles of the earth speed change only, can realize that so display screen manually slides; The upset driving-chain is longer, and number of steps of speeds is more, and terminal gear has six grades of speed changes, and is bigger to clutch 19 place's transmission efficiency losses as reverse movement, therefore is difficult to realize manual upset.
As shown in Figure 2, at gear box one slide block 9 is housed each side, slide block 9 is provided with chute 9-1, and the left and right sides of gear box 16 is fixed with and is positioned at the sliding pin 16-1 that chute 9-1 slides, and appropriate location, gear box 16 both sides is provided with the spacing block rubber 16-2 of slide block slip; On the gear box 16 that is positioned at sector 25 corresponding positions, also be fixed with two guide vane end stop 16-3; Also rivet the guide rail (not shown) that " L " type is arranged on the casing of the gear housing left and right sides relatively, the horizontal short straight flange of guide rail is hooked in the slide block chute.
Sliding pin 16-1 riveting is on gear box 16, but gear box 16 and slide block 9 slide relative can stop to move when slide block is met fixing rubber 16-2.(slide block stands in and can slide on the guide rail on the casing in riveting with the gear box group), sliding pin 16-1 can slide into the other end from an end on the gear box 16 in slide block 9 chute 9-1, increases the slippage of gear box 16 with respect to casing.The two guide vane end stop 16-3 of place can limit the display screen flip angle on the gear box, state shown in Figure 2 is that a guide vane end stop 16-3 withstands display screen bonnet 1 and is in horizontal state, the flip angle of display screen is not only limited in mechanism, also can limit by the counting by potentiometer on software program on the other hand.It is the rotation number of teeth by the potentiometer counting gear that the moving forward and backward of display screen becoming upset, provides stopping of motor or starting command realizes by software program among the CPU.
As shown in Figure 3, the display screen bonnet 1 and first sector 25 have corresponding rivet hole 25-1, pass rivet hole with rivet 25-1 the rivet riveting can firmly be connected first sector 25 and display screen bonnet 1 on gear 24 and display screen bonnet 1.
Because of always there being error on the structure, the CPU software program is write and can only be provided a certain action of realization in a certain scope of potentiometer counting.Transfer upset to as moving, transfer to mobile etc.When display screen transfers to when mobile from upset, require the display screen state that is up to the standard, at this moment; excessive for preventing the display screen flip angle, can be made as no dentation at the 25-2 place as shown, an end place of sector, and slightly protruding; can prevent first gear 25 to be rotated further, play spacing and protective effect.
As shown in Figure 4, above-mentioned first second clutch 7,19 is stacked successively by steel bushing 7-5 and snap ring and is fixed by the gear wheel 7-1 on it, friction plate 7-2, pinion 7-3, spring 7-4, packing ring, compress the back snap ring and snap in the steel bushing 7-5 annular groove, gear 7-1 and gear 7-3 pass through overall viewing range.
Torsion spring set shown in Figure 5 penetrates on the axle, and the one end inserts second gear, 4 end-face holes, and the other end is installed in support on the gear housing 16 and pushes down and maintain static.When gear rotates, spring one end and second gear 4 rotate synchronously, when the gear rotation direction was consistent with the spring rotation direction, spring wrapped tighter and tighter, and gear is subjected to reactive torque, it is too fast to prevent that gear from rotating, play damping action, when gear forwards maximum angle to, stop, the reactive torque maximum that this moment, spring produced, the diastema swing torsion that two meshing gear backlash accumulated errors are caused is bigger, promptly can not swing easily.
