Description
Technical field
The utility model relates to a kind of car headlamp automatic flushing device, belongs to automobile-used field of illumination lamp technology.
Background technology
Automobile in the process of moving, if head lamp is covered by earth or other pollutantss, the penetrance of light and intensity can be weakened greatly, also just can't guarantee sufficient road illumination, can produce a very large impact traffic safety, have head light washing system just can address this problem masterlyly.And relevant national standard regulation, car headlamp use high-voltage gas discharging light as light source, must be furnished with washing equipment.Existing head light washing system mostly is its action of manual control, needs personnel to participate in judging and operation, when chaufeur thinks that head lamp is subjected to that pollutants blocks, during the obvious deepening of light, just open washing equipment head lamp is cleaned.
The utility model content
The purpose of this utility model is to provide a kind of reliable operation, car headlamp automatic flushing device that degree of automation is high.
The utility model is that the technical scheme that achieves the above object is: a kind of car headlamp automatic flushing device, it is characterized in that: comprise wiper mechanism, sensor and the controller that is used to control wiper mechanism work, described plural sensor is installed in the head lamp at interval, the mouth of each sensor is connected with controller, described wiper mechanism comprises the L-shaped support tube of hollow, sealing is installed in telescopic pipe and the check valve that has runner in the support tube, two nozzles and top cover, the support tube one end that is installed on the car body is connected with the feed liquor switch, the feed liquor switch is connected with the mouth of controller, check valve is installed on the telescopic pipe, two nozzles are installed on the telescopic pipe and are positioned at the top of check valve, and top cover is connected with the top of telescopic pipe.
The utility model is equipped with plural sensor in head lamp, make each sensor be installed in the diverse location of head lamp, the signal that reflects by each sensor head lamp lampshade also inputs in the controller, controller can detect the clean condition on lampshade surface according to sensor, and the output control signal acts on the wiper mechanism action.When lampshade cleaning, then sensor reflects than weak signal to the head lamp lampshade, this moment controller receive sensor than after the weak signal, judge the lampshade cleaning surfaces, and need not cleaning.And shelter is arranged when lampshade, and then sensor reflects strong signal to the head lamp lampshade, after this moment, controller received the strong signal of sensor, and judges that the lampshade surface needs to clean, and the controller wiper mechanism moves and cleans.The utility model judges by the signal that controller received whether control wiper mechanism moves, in time head lamp is cleaned, guarantee the luminous intensity distribution performance requirement of head lamp,, thereby realized head lamp is carried out automated washing because cleaning process need not manual operation.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is that the utility model is installed in the structural representation on the vehicle frame.
Fig. 2 is the structural representation after the utility model cleaning machine mechanism, sensor and head lamp are installed.
Fig. 3 is the A-A sectional structure scheme drawing of Fig. 2.
Structural representation when Fig. 4 is the work of utility model wiper mechanism.
Wherein: 1-wiper mechanism, 1-1-top cover, 1-2-telescopic pipe, 1-3-nozzle, 1-4-check valve, 1-5-support tube, 2-sensor, 3-controller, 4-head lamp, 5-car body.
The specific embodiment
See shown in Fig. 1～4, car headlamp automatic flushing device of the present utility model, comprise wiper mechanism 1, sensor 2 and the controller 3 that is used to control wiper mechanism 1 work, plural sensor 2 is installed in the head lamp 4 at interval, adopt a plurality of sensors 2 simultaneously head lamp lampshade zones of different place to be detected, thereby enlarge the scope that detects, improve accuracy of detection, the mouth of each sensor 2 is connected with controller 3, to detect the signal that the head lamp lampshade reflects by sensor 2 and reach controller 3, when sensor 2 detects signal that the head lamp lampshade reflects when more weak, controller 3 is judged the lampshade cleaning surfaces; When sensor 2 detects signal that the head lamp lampshade reflects when strong, controller 3 judges that the lampshade surfaces have shelter to need to clean.See shown in Fig. 1～4, wiper mechanism 1 of the present utility model comprises the L-shaped support tube 1-5 of hollow, sealing is installed in telescopic pipe 1-2 and the check valve 1-4 that has runner in the support tube 1-5, two nozzle 1-3 and top cover 1-1, the support tube 1-5 one end that is installed on the car body 5 is connected with the feed liquor switch, the feed liquor switch then is connected with the mouth of controller 3, opening the feed liquor switch by controller 3 realizes head lamp 4 is cleaned, telescopic pipe 1-2 can move axially in the support tube 1-5 and sealing is installed in, on the utility model telescopic pipe 1-2 check valve 1-4 is installed, prevent that by check valve 1-4 cleaning liquid from refluxing, and two nozzle 1-3 are installed in the top that telescopic pipe 1-2 went up and be positioned at check valve 1-4, see Fig. 2, shown in 4, this two nozzle 1-3 is vertically tilting along lampshade, to reach cleaning performance preferably, by two nozzle 1-3 cleaning liquid being sprayed onto head lamp lampshade surface cleans, and top cover 1-1 is connected with telescopic pipe 1-2 top, see shown in Fig. 2～3, as telescopic pipe 1-2 during at the lower limit bit position, its top cover 1-1 maintains an equal level mutually with the lampshade of car cover and head lamp, and as telescopic pipe 1-2 during at upper limit bit position, two nozzle 1-3 are positioned at the top of head lamp lampshade, and head lamp lampshade outside is cleaned.Controller 3 of the present utility model can be installed in the operator's compartment, but manual operation controller 3 starts 1 pair of head lamp 4 of wiper mechanism and cleans.
