Present new forms of energy car has entered the visual field of people, with its environmental protection by people are familiar with; Each border, the world is all at popularization new forms of energy car; New forms of energy car in electrical store on ventilation fan all can be installed be exhausted in storehouse, the object of exhaust is exactly the foul atmosphere that will remove in car, regulates temperature, humidity.The air outlet installation site that existing ventilation fan is provided with compared with low, air outlet area is little, resistance is larger comparatively large at unit interval loss air quantity, so total ventilation volume is less, easily make vehicle interior temperature raise, generation high temperature alarm, has a strong impact on normal vehicle operation.In addition in rainy day vehicle travel process, rainwater and wind also from air outlet into the car, can affect the electric elements in work, greatly reduce the working life of electric elements; Also have when vehicle is out of service, the foreign material such as snowflake, leaf easily by air outlet into the car, easily damage vehicle core component.
Summary of the invention
For above-mentioned defect, the purpose of this utility model is to provide a kind of ventilation fan air port mechanism for opening/closing, rotate control cincture moving cam mechanism by folding motor and carry out upper and lower activity, make reversing device be that fulcrum rotates with one end, thus complete air opening plate and move up and down; By air port mechanism for opening/closing, ensure that other foreign material such as rainwater, wind cannot enter in electrical store and damage electric elements, also substantially increase ventilation during ventilation simultaneously, effectively can carry out rapidly ventilation, temperature adjustment work in electrical store, under preventing hot operation, electrical equipment damages.
The technical solution of the utility model is achieved in the following ways: a kind of ventilation fan air port mechanism for opening/closing, be made up of air opening plate, folding motor, reversing device, described air opening plate is provided with two erection columns, air opening plate is arranged on reversing device front end by erection column, and reversing device tail end internal fixtion is provided with folding motor; It is characterized in that: described reversing device is made up of two connecting pins, fixed mount, two connecting plates, portable plate, cam push pedals, and two connecting plates are movably connected in the two ends of portable plate by two connecting pins respectively; Cam push pedal is fixedly mounted on inside the connecting pin of portable plate front end, and portable plate is fixed on fixed mount by the connecting plate of tail end; Described air opening plate is fixedly mounted on the connecting plate of portable plate front end; Described folding motor is fixedly mounted in fixed mount, and folding motor is provided with cam mechanism, and cam mechanism is flexibly connected with cam push pedal.
Described air opening plate border is provided with sealing gasket, and sealing gasket is pasted by gum and is connected on air opening plate.
Described air opening plate is provided with reinforcement.
Described cam push pedal is provided with an ellipse shape hole, and cam mechanism completes through ellipse shape hole and is flexibly connected with cam push pedal.
Described folding motor junction block is arranged on fixed mount.
The utility model, structure is simple, quick and easy for installation, ensure that other foreign material such as rainwater, wind cannot enter in electrical store and damage electric elements, also substantially increase ventilation during ventilation simultaneously, effectively can carry out rapidly ventilation, temperature adjustment work in electrical store, under preventing hot operation, electrical equipment damages.
