The specific embodiment
The technical solution of the present invention is further explained below in conjunction with drawings and Examples, but following content is not intended to limit the scope of the invention.
Present embodiment provides a kind of onboard navigation system sliding turnover driving device, the motion of this homing advice read-out as shown in Figure 1, among Fig. 1: cabinet 1, read-out 2, base 3, connecting rod 4, slide block 5, crank 6, tooth bar 7, chute 8.This driving device must stretch out cabinet and overturn about 95 by the driving display screen on even keel
0, provide reliable and stable support for read-out simultaneously.
As shown in Figure 2, driving device is divided into two parts by function, among Fig. 2: read-out 2, base 3, crank 6, tooth bar 7, sliding pin 9, torsion spring 10, motor 11.First is motor-driven pinion and rack, is fixed drive source than transmission, can realize the front and back motion of translation of base; Second portion is a piston crank mechanism, retrains by the propulsive effort of first's generation and the chute of crank self. realize the rotational motion of crank, driving display screen realizes upset.The mechanism kinematic process is divided into two stages: read-out is contracted in cabinet inside when initial, after motor is started working, carries out motion of translation by the first cover driver train, and read-out is stretched out casing, and this stage connecting rod mechanism is not worked.After the read-out major part was stretched out casing, the sliding pin of crank entered the upset conduit, and connecting rod begins to launch, and driving display screen realizes upset, and realized stable support.System's inverse motion during the motor counter-rotation is in read-out withdrawal cabinet.In the whole motion process, rely on auxiliary members such as chute, slide block, sliding pin, roller and torsion spring to guarantee motion steadily, and reduce noise and vibration to greatest extent.
Described translational drive mechanism is motor-driven pinion and rack, is installed on the base, and tooth bar is fixed on the cabinet, drives the front and back translation of base plate and read-out, and transmission principle as shown in Figure 2.Require this device under the situation of little load, motion is steady, and speed is moderate.This driver train adopts DC micromotor with low cost and the multistage messenger chain of little modulus injection made gear to realize bigger reduction ratio.For improving driving efficiency, injection moulding worm screw-an oblique gear mechanism of big speed ratio has been adopted in first order transmission, is characterized in that processing and manufacturing is simple, cost is low.Owing to do not need self-locking, adopt the worm screw of bull (z1=3), lift angle λ=ll
0The injection moulding cylindrical wheel precision height of following stages, stable working, noise are low, have absorbing and self-lubricating property.The afterbody of conduction is a tooth bar, and messenger chain is divided into two-way to keep moving equilibrium here, can prevent the deflection of mechanism kinematic direction by the guide groove of making on the tooth bar.Be the stationarity and the guidance quality that guarantee that the base motion is supported, each fixes a chute in the cabinet both sides, and base slides in chute by two plastic slide blocks.
As shown in Figure 3, adopt piston crank mechanism to realize the upset of read-out here, this mechanism is installed in the both sides of device symmetrically.The chute constraint of mechanism's propulsive effort that motion produces by base and crank self realizes the rotational motion of crank, and then driving display screen (connecting rod) upset, so the curve shape of base translational velocity and chute has determined the speed and the position of read-out upset.In the starting stage of motion, chute is a straight line, crank and horizontal included angle 1=0
0, connecting rod (read-out) and horizontal included angle 3=180
0, this moment, piston crank mechanism did not launch, and read-out is followed the base horizontal motion.After the read-out major part was stretched out cabinet, because chute enters curve, φ 1 strengthened, the crank setting in motion, and driving display screen begins turning, and when telltale turn to predetermined angular, chute played the position-limiting action (see figure 1) again.The independently moving mode that this aggregate motion overturns after finishing than translation is again compared and has been saved run duration and space.Screen position as requested and each known length of connecting rod can be determined chute curve initial sum final position.Suppose pole length L1=25 mm, L2=56.6 mm, L3=17.5 mm, L4=61.2 mm, requirement
The range of movement of φ 3 is 0
0~ 95
0
According to above relational expression, can calculate φ 1 and φ 3, corresponding numerical value.Result of calculation is:
This moment the chute terminal point minimum constructive height H=19 mm.
By setting the curvature of upset chute, the motion path of may command piston crank mechanism gets final product position, speed and acceleration/accel that control display screen is moved, and chute has adopted the form that multistage straight line and arc transition are joined here.
The constructional feature of present embodiment device is that the centroidal distance centre of gration of read-out is far away, change in torque is bigger during upset, and it is short, in light weight as the base length of flip-flop movement support platform, and base self need carry out front and back and slide, so the rigidity of enhanced system how. guarantee mass motion particularly the stationarity of flip-flop movement be a content that needs emphasis to consider.Here taked aggregate measures to solve this problem.On the one hand, base adopts multi-point support, at first increases the motion slide block length and the quality of fit at rear portion, both sides, secondly increases plastic slide block in base middle front part position and prevents structural distortion and play a supportive role.Increase idler wheel support structure in the base front part sides in addition, on the one hand to the anterior stable support that forms of support, friction force is inhomogeneous and cause pulsation and sense of motion deflection in the time of can preventing sliding stop on the other hand.5 supporting constructions have like this guaranteed the stability of base.The read-out of upset structurally as connecting rod, has been equivalent to form 4 bigger supporting constructions of area, has strengthened its structural stability, and can play the effect of vibration damping and absorbing.The torsion spring of the left and right sides produces the anticlockwise direction moment of torsion in addition, form big damping, gear return difference and gap in the time of can eliminating motion, when reducing the read-out upset because inhomogeneous vibration that may cause of load and shake, robust motion when increasing upset, and can offset the read-out level attitude time because the sagging bowing phenomena of front end that gravity causes makes the read-out translation stage can remain level attitude.
By above embodiment as can be seen, method by mechanism's combination has realized that single drive source realization two dimension drives, and compared with two-dimentional independent drive, has not only saved a cover driver train, and mechanism's rigidity and good integrity after the combination, can reduce motion of mechanism scope and complexity.Evidence, this mechanism kinematic links up smooth, has reached practical requirement.
