Abstract
The utility model provides a power switching circuit of a hybrid bus air conditioning fan. The power switching circuit comprises an air conditioning fan unit, an air conditioner control box, an air conditioner control component, a low-voltage storage battery and a switching relay. A static contact of the switching relay is electrically connected to the air conditioning fan unit through the air conditioner control box, and a dynamic contact is electrically connected to the low-voltage storage battery through a fuse; one end of a coil of the switching relay is electrically connected to air conditioner control component through an air conditioner control wire, and the other end is electrically connected to the low-voltage storage battery through a key switch. According to the power switching circuit, after an engine is shut down, the low-voltage storage battery is capable of supplying work power for the air conditioning fan unit to guarantee the air conditioning fan unit to operate continuously, retained cool air in an air outlet can be blew into a vehicle for ventilation, and energy waste is avoided. The power switching circuit is convenient to mount and use and reliable in performance.
Description
Technical field
The utility model relates to hybrid power passenger car technical field, specifically a kind of power supply switch circuit of hybrid power passenger car air-conditioning draught fan.
Background technology
At present; hybrid power passenger car is for improving fuel saving ratio; major part all has engine idle stopping function; and general hybrid power passenger car air-conditioning used is all traditional air-conditioning; must rely on driven by engine to work, therefore when after engine shutdown, air-conditioning also can quit work; air-conditioning draught fan cannot blow to the residue cold wind of air outlet in car in time, causes energy dissipation.
Utility model content
The purpose of this utility model is to provide a kind of power supply switch circuit of hybrid power passenger car air-conditioning draught fan, can realize air-conditioning draught fan still can normally dry when the engine shutdown by this circuit.
The technical solution of the utility model is:
A power supply switch circuit for hybrid power passenger car air-conditioning draught fan, comprises air-conditioning draught fan unit, air-conditioner control box, air-conditioning control assembly, also comprises low tension battery and transfer relay; The break back contact of described transfer relay is electrically connected with air-conditioning draught fan unit by air-conditioner control box, and moving contact is electrically connected with low tension battery by wire fuse; Coil one end of described transfer relay is electrically connected with air-conditioning control assembly by air-conditioning control line, and the other end is electrically connected with low tension battery by key switch.
The power supply switch circuit of described hybrid power passenger car air-conditioning draught fan, also comprise super capacitor, battery charger and battery charger switch, the mouth of described super capacitor is electrically connected with the input end of low tension battery by battery charger, described battery charger switch is electrically connected with battery charger, for controlling being switched on or switched off of battery charger.
The power supply switch circuit of described hybrid power passenger car air-conditioning draught fan, described battery charger switch is arranged on instrument desk.
As shown from the above technical solution, low tension battery of the present utility model can be for air-conditioning draught fan unit provides working power after engine shutdown, guarantees that air-conditioning draught fan unit can remain in operation, and air outlet remained to cold wind and blow in time in car, for to taking a breath in car, avoid energy dissipation; The utility model installation, easy to use, dependable performance.
As preferably, by battery charger, the electricity of super capacitor is supplied with to low tension battery, guarantee after engine shutdown that low tension battery can power shortage; Battery charger switch is arranged on instrument desk, is convenient to driver's operation.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Detailed description of the invention
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a power supply switch circuit for hybrid power passenger car air-conditioning draught fan, comprises air-conditioning draught fan unit 1, air-conditioner control box 2, low tension battery 3, air-conditioning control assembly 4, transfer relay 5, wire fuse 6, air-conditioning control line 7, key switch 8, super capacitor 9, battery charger 10 and battery charger switch 11.The break back contact of transfer relay 5 is electrically connected with air-conditioning draught fan unit 1 by air-conditioner control box 2, and moving contact is electrically connected with low tension battery 3 by wire fuse 6; Coil one end of transfer relay 5 is electrically connected with air-conditioning control assembly 4 by air-conditioning control line 7, and the other end is electrically connected with low tension battery 3 by key switch 8.The mouth of super capacitor 9 is electrically connected with the input end of low tension battery 3 by battery charger 10, and battery charger switch 11 is electrically connected with battery charger 10, and for controlling being switched on or switched off of battery charger 10, battery charger switch 11 is arranged on instrument desk.The capacity of low tension battery 3 is 24V, and the horsepower output of battery charger 10 is 2000 watts.
Principle of work of the present utility model:
When driving engine reaches after correlated condition shutdown; air-conditioning quits work; the air-conditioning control assembly 4 at air-conditioning top is exported earth signal; arrive coil one end of transfer relay 5 via air-conditioning control line 7; because the coil other end of transfer relay 5 connects low tension battery 3 by key switch 8; so now coil electricity of transfer relay 5; the moving contact of transfer relay 5 and break back contact adhesive; the electricity of low tension battery 3 is supplied with air-conditioning draught fan unit 1 by air-conditioner control box 2, makes air-conditioning draught fan unit 1 blowing of can normally working.In the time that the electric weight of low tension battery 3 is low, press the battery charger switch 11 on instrument desk, battery charger 10 just can be supplied with low tension battery 3 by the electricity of super capacitor 9, prevent low tension battery 3 power shortages.
The above embodiment is only that preferred implementation of the present utility model is described; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
