The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail:
The utility model provides a kind of can replace traditional rear-view mirror back vision function in the rainy day, solution is because of back mirror and the fuzzy device that affects backsight effect of both sides front window, this device is practical, easy to use, chaufeur only need be controlled this device until meet user demand and so clear that to see automobile rear situation clearly by read-out in car by switch.
As a kind of specific embodiment of the utility model, the utility model provides a kind of automobile rainy day rear-view mirror device as shown in Figure 1, comprise air compressor 2, storage tank 5, electric water pump 8, fluid reservoir 9, camera 12 and read-out 19, vehicle right and left both sides rear end panel 16 has groove, in the groove of described vehicle right and left both sides rear end panel 16, there is rubber outer rim 18, in described rubber outer rim 18, there are left side shooting skull interface 14 and right side shooting skull interface 17, in described left side shooting skull interface 14 and right side shooting skull interface 17, there is camera 13, there is preposition eyeglass 12 described camera 13 ends, there is induction tract described air compressor 2 one end, described air compressor 2 other ends are connected with storage tank 5 by connecting tube, between described air compressor 2 and storage tank 5, in connecting tube, there is internal check valve 3, described storage tank 5 one sides have side check valve 4, described storage tank 5 one end are connected with vent pipe 10 by connecting tube, on connecting tube between described storage tank 5 and vent pipe 10, there is air extractor duct 7, described vent pipe 10 has a middle part pipeline, the middle part pipeline of described vent pipe 10 is connected with fluid reservoir 9 by electric water pump 8, described vent pipe 10 has two outgassing nozzles, the mouth mouth of two outgassing nozzles of described vent pipe 10 is the preposition eyeglass 12 of the camera 13 of the corresponding left and right sides respectively, the end face fluted 21 of described automobile operative position, described read-out 19 is arranged on groove 21 sides by hinge 20, described air compressor 2 is connected with the read-out 19 of automobile operative position by connection lead.
(1) design intelligent back vision device structure.As Fig. 1, A, B represent to come respectively the hot air of automatic heat-exchanger and from the cold air of engine air inlet tube, cold and hot air is respectively by valve 1,2, in pressure chamber 3, mix, and enter storage tank 5 by check valve 4, then by valve 6, enter respectively two air extractor ducts 7,8, thereby realize the clean of the preposition eyeglass of camera.For preventing the too high or too low working effect that affects of storage tank air pressure, should guarantee that storage tank pressure is tending towards steady state value, therefore design check valve 4, valve closing when storage tank air pressure surpasses design value, storage tank stops air inlet, when storage tank pressure is reduced to design value, valve 4 is opened, and continues air inlet, thereby realizes storage tank constant pressure.In order to prevent causing regulating air chamber 3 internal gas pressures too high without air inlet for a long time because of storage tank, on 3, designed check valve 9, when in air chamber 3, mixture pressure surpasses design value, check valve 9 is opened, be connected valve closing when pressure is reduced to design value with atmosphere.Valve 1,2,6 all drives by stepping motor, to realize accurate control.
(2) design camera lens cleaning device (in conjunction with Fig. 2,3,4).As shown in Figure 2,3, the spiral lamination (negative thread) that 10 place's spiral laminations (outside thread) cover with camera is connected, and is connected with 17 places in Fig. 4, takes off lid in the time of need to using this device, can screw on lid in case eyeglass is dirty or damage while not needing to use.Camera is positioned at preposition eyeglass 14 midways location, and air extractor duct 11 inner portion are provided with two tongue pieces 12, to accelerate air-flow velocity, thereby keep eyeglass 14 being positioned at the clean of place, camera dead ahead, rainwater flows down along conical suface, and the lowest part 10 leaves otch 15, to discharge rainwater.This device and camera are arranged on rear end panel by support.
(3) step motor control system is set.In conjunction with Fig. 8, the switching of this rear-view mirror device by micro controller system according to rain sensor signal control, rain sensor is arranged on automobile rearview mirror and both sides front window, when sensor senses to raindrop amount compared with large and when affecting back mirror and normally working, micro controller system is controlled rear-view mirror device and is automatically opened, otherwise this device is closed automatically.Two switches are set in Automobile instrument appropriate location, are respectively air inlet master cock, the master cock of giving vent to anger.As Fig. 5, air inlet master cock is double pole double throw formula switch, always has 4 external pins
,
,
,
, switch simultaneously with
,
or
,
connect, in conjunction with Fig. 1, while supposing valve clickwise here, motor is main story, otherwise is reversion, and when whole device is worked, valve 1,2 is not respectively contract fully, full open mode, when switch simultaneously with
,
or
,
during connection, valve 1,2 hand of rotation regulate to realize miscellaneous gas temperature on the contrary.If when work switch simultaneously with
,
connect, micro controller system moves with drive motor to stepper motor driver input corresponding pulses respectively, micro controller system often sends a pulse, rolling counters forward is once also cumulative, now valve 1 reversion, valve 2 forwards, can increase like this in mixture gas hot gas amount and reduce air conditioning quantity, realizing mixture gas heats, when reaching preset times, rolling counters forward (can design by programming, in the time of should guaranteeing to reach this number of times during design, each valve angle stroke is 90 °) time, micro controller system stops exporting pulse, motor stop motion.If chaufeur by switch with
,
connect, micro controller system sends the pulse of opposite direction simultaneously, and rolling counters forward reduces, and now valve 1 forward, valve 2 reversions, realize mixture gas cooling, and when rolling counters forward is zero, micro controller system stops exporting pulse, motor stop motion.As Fig. 6, the master cock of giving vent to anger is single-pole double-throw type switch, chaufeur can be controlled the speed of giving vent to anger (regulating the aperture of valve 6 to realize by control step motor) by this switch, this switch has 2 external pin C, D, represent respectively motor main story, reversion, valve initial condition is contract fully, in conjunction with Fig. 7, when switch is connected with pin C, micro controller system is inputted corresponding pulses with drive motor main story to stepper motor driver, thereby realizing gas flow rate accelerates, micro controller system often sends a pulse, rolling counters forward is once also cumulative, when reaching preset times, rolling counters forward (can design by programming, in the time of should guaranteeing to reach this number of times during design, each valve angle stroke is 90 °) time, micro controller system stops exporting pulse, motor stop motion.In like manner, when switch is connected with pin D, motor reversal, realizes gas flow rate and reduces, and rolling counters forward reduces, and when rolling counters forward is zero, micro controller system stops exporting pulse, motor stop motion.Described two switches be used in conjunction with can implement device effective adjusting.
(4) read-out is set.In driving, pilot's line of vision is all generally look straight ahead, and often need to watch back mirror, therefore the read-out of this rear-view mirror device is arranged on the Automobile instrument upper left corner, and, near left side back mirror, chaufeur neither needs to bow and watches and can be combined with back mirror.As Fig. 7, read-out 18 is placed in the groove 20 on instrument carrier panel, in read-out lower end, by hinge 19, is connected with groove, to realize read-out rotation, can rout up read-out, otherwise read-out can be regained when needs are used.
The above; it is only preferred embodiment of the present utility model; be not the utility model to be done to the restriction of any other form, and according to any modification or equivalent variations that technical spirit of the present utility model is done, still belong to the utility model scope required for protection.
