Abstract

When a fuel vehicle is transformed into a blade electric vehicle, if a cold and warm air operating switch of the original vehicle is of a manual rotary handle structure, in order to achieve the purposes that after transformation, the starting operating habit of a warm air system stipulated by the original vehicle is not changed and a clean, tidy and coordinative instrument desk face of the original vehicle is not damaged, a small magnetic sheet is bonded to the back face of an arrow portion of a manual rotary handle; holes are punched in scale lines of a gear dial of a fan heater, localization of the holes is used, so that patch type Hall switch elements are bonded to the back faces, inside an instrument desk, of the holes; and when the handle is rotated to different gears, under the effect of the small magnetic sheet on the back face of the handle, the different Hall switch elements can be connected to drive an amplification circuit, one or more electric heating elements are connected, and a driver can start the fan heater and adjust the warm air amount at will completely according to the operating habit of the fuel vehicle.

Description

The type selecting of pure electric automobile warm-air drier switch and setting

Technical field: the present invention relates to pure electric automobile warm air system design on control circuit. It is specifically related to warm-air drier switch type selecting and setting, by reasonable selection, warm-air drier switch is set, reach namely not destroy clean and tidy, the coordination of former car instrument table top, do not change again the manipulation order of former car warm-air drier switch.

Background technology: after making a fuel-engined vehicle into pure electric automobile, except correctly matching the major electrical equipment elements such as motor, controller, set of cells, cold, warm braw equipped on former car are arranged and be also required for being modified design by the pattern of pure electric automobile. The refrigeration compressor that since engine drags is carried out in the cold wind source of fuel-engined vehicle; The exhaust heat that warm braw source produces when carrying out since engine work, converts warm braw to by a water-air heater. Demand according to driver, selects to use cold wind or warm braw by a turn handle. Concrete structure is as indicated with 1. Cold air selects handle generally all on the instrument face platform of driver's right-hand side. Handle to the left or during turn to the right, makes warm braw or cold wind by the unlatching of the valve plates of two linkages respectively, selects the main air duct allowing warm braw or cold wind enter automobile, by an axial flow blower, cold or warm braw are delivered to each position. In major part, on low-grade car, the turn of handle and cold, warm braw linkage valve plate is selected to be completed by Bowden cable and mechanical linkage.

But, this linkage can only control to select cold wind or warm braw to enter main air duct, and the startup producing the compressor of cold wind and the warm-air drier of generation warm braw also needs to other controlling unit. For most of automobiles, the startup of compressor generally all separately arranges a switch on instrument table top and completes. The generation in warm braw source is then produces Tong Bu with the work of electromotor. As long as electromotor operates, just necessarily having warm braw to produce, during use, allow it enter main air duct, the used time does not allow it discharge outside car.

After making pure electric automobile into, owing to electromotor is cancelled, it does not have warm braw source, if needing warm braw, it is necessary for producing warm braw source by the electric heater additionally arranged. This electric heater when by the position of handle rotation direction warm braw, must be connected another and control switch, make electric heater energising work again. Does is problem that where the switch of this increase is arranged on?Use which type of switch suitable?

Space layout on the instrument table top of automobile is spick-and-span, coordination, and a switch is installed in punching herein above, destroys clean and tidy, the coordination of former car on the one hand; Also change former car on the other hand and enable the manipulation custom of warm braw, add again an independent switch motion.

When reequiping all types of electric automobile, how to keep the structure of former car, parameter and manipulation custom not to change as much as possible, be a problem must be noted that of pure electric automobile designer.

Summary of the invention: in order to reach namely not destroy clean and tidy, the coordination of former car instrument table top, keep again the manipulation custom that former car warm air system starts, the present invention adopts the cold air at former car to select the back side, handle arrow position to paste a little magnetic sheet, make a call to the aperture of 41 millimeter the 0 of warm braw side, on I, II, III gear line, select the handle graduated disc back side (inside instrument desk) to paste a Hall paster switch at cold air. Make paster switching center position alignment apertures, so, as long as turn handle is to warm braw side I shelves, Hall paster switchs under the sensing of little magnetic sheet, will export a switch electricity, drive a set of amplifying circuit, make electric warm-air machine energising work, produce warm braw and enter main air duct of automobile, Using such method, it is also possible on the different gears of warm braw shelves, several Hall paster switch is set more, it is screwed into different gear, it is possible to connect one or more electrical heating elements, reaches to produce the effect of different warm braw power. Owing to commercially available little magnetic sheet and paster Hall switching element minimum gauge only have a few mm square, it is respectively adhered on again the swing handle back side and the graduated disc back side, has namely reached not affect that automobile instrument table top is clean and tidy, coordinated; Maintaining again the manipulation custom of former car completely, fill use through reality, effect is fine.

Accompanying drawing illustrates:

Accompanying drawing 1 is in major part, low-grade car warm braw selects handle rotating mechanism schematic diagram.

It it is the schematic diagram of concrete structure of the present invention and using method shown in accompanying drawing 2.

Detailed description of the invention: after confirming that the automobile cold air being adapted selects control mode to belong to said structure, shown in Fig. 2: cold air first selects handle 1 pull down, be stained with a sizeable little magnetic sheet 2 in the groove at its arrow end back side. Magnetic sheet paste position is close proximity to arrow end. By designing requirement the 0 of warm braw side, I, II, III gear line is beatenThe aperture 3 of individual 1 millimeter, cements SMD Hall switching element centre from alignment apertures inside instrument desk, willThe extraction wire harness 5 of individual Hall switching element fixes, and guides on electric heater drive circuit board 6. so, when driver needs out warm braw, as long as turn handle is to warm braw side the first gear, namely corresponding Hall element is switched on, by amplifying circuit self-locking and make the heating of electric heater a part of element, if continuing turn handle to the second gear, a Hall element is had again to be switched on, by amplifying circuit self-locking and make electric heater another subelement heating ..., in this approach, just can reach arbitrarily adjustment warm braw watt level, when not needing warm braw, handle is screwed into " 0 " position, drive amplification circuit dead electricity, electric heater stops heating, return to original state. reach neither to increase switch element and complied fully with again the purpose of former car manipulation custom.
