The air conditioning for automobiles potentiometer structural representation that Fig. 1 provides for a kind of embodiment of the present invention.
Embodiment
Core of the present invention is to provide a kind of air conditioning for automobiles potentiometer, can solve the problem that potentiometer is expensive and procurement cycle is long.
In order to enable above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Set forth detail in the following description so that fully understand the present invention.But the present invention can be different from alternate manner described here to implement with multiple, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention.Therefore the present invention is not by the restriction of following public concrete enforcement.
Please refer to Fig. 1, the air conditioning for automobiles potentiometer structural representation that Fig. 1 provides for a kind of embodiment of the present invention.
In a kind of embodiment of the present invention, a kind of air conditioning for automobiles potentiometer, comprise: potentiometer base plate 1, the side of potentiometer base plate 1 is provided with n bar non-touching metal gear contact chip 2, n be greater than 1 integer, the opposite side of potentiometer base plate 1 is provided with the corresponding resistance of each metal gear contact chip 2 of connecting, and potentiometer base plate 1 is also provided with contact portion, and contact portion is included in the brush of movement on each metal gear contact chip 2.Wherein, preferred potentiometer base plate 1 is pcb board, and metal gear contact chip 2 is copper brush sheet.Further preferable alloy gear contact chip 2 is circular arc copper brush sheet, the concyclic heart of each metal gear contact chip 2, and is radially arranged in order from inside to outside.
As shown in Figure 1, Fig. 1 is described to comprise 4 strip metal gear contact chips, and namely n is 4, it should be noted that, can arrange the metal gear contact chip that arbitrary number is greater than 2 as required, present embodiment does not limit this, specifically depends on the circumstances.
In the present embodiment, metal gear contact chip is set in the side of potentiometer base plate, metal gear contact chip is just as the gear contact with brush electrical contact, itself can be considered as without resistance, and between each metal gear contact chip, be provided with the resistance of preset resistive value, the resistance of each resistance can be the same or different, and sets according to actual needs.Each metal gear contact chip is by being positioned at the resistant series of dorsal part, when the brush of metal gear contact chip homonymy switches mobile between each metal gear contact chip, resistance then between the metal gear contact chip at two ends and brush will change, thus produces different signals.Metal gear contact chip as being positioned at two ends connects power supply, then, when brush switches mobile between different metal gear contact chips, output will export different magnitudes of voltage.
When making, only need at the side fixing metal gear contact chip of potentiometer base plate, at dorsal part fixed resistance, to substitute the high resistive element directly contacted with brush of price in existing potentiometer, and resistance is connected with the metal gear contact chip of each correspondence.Especially potentiometer base plate adopts pcb board, and metal gear contact chip is copper brush sheet, makes simple, cheap, can solve the problem that potentiometer is expensive and procurement cycle is long.
Wherein, metal gear contact chip is circular arc copper brush sheet, the concyclic heart of each metal gear contact chip, and is radially arranged in order from inside to outside.Such brush can move on each metal gear contact chip by rotating, and reduces the volume of potentiometer, has saved cost.
On the basis of above-mentioned execution mode, in one embodiment of the invention, be positioned at outermost metal gear contact chip and comprise the discrete sub-copper brush sheet of m sheet, m be greater than 1 integer, and every slice, thin piece copper brush sheet is connected with the most contiguous metal gear contact chip by the resistance of different resistance.
When brush be positioned at outermost metal gear contact chip slides time, and be connected with the most contiguous metal gear contact chip due to the resistance of every slice, thin piece copper brush sheet by different resistance, the sub-copper brush sheet often sliding into different sheet can obtain different output signals.The most contiguous so-called metal gear contact chip refers to the descending arrangement of radius, comes deputy metal gear contact chip.Each resistance between outermost metal gear contact chip and this most contiguous metal gear contact chip can increase in sequence successively, and the difference between every two resistance is without the need to too large, when such brush moves on outermost metal gear contact chip, the signal value be more or less the same can be obtained by potentiometer, namely can realize fine setting.
Certainly, each resistance between each sub-copper brush sheet and the most contiguous metal gear contact chip sets according to actual needs.In a specific embodiment, the side of the potentiometer base plate of air conditioning for automobiles potentiometer is provided with two metal gear contact chips directly do not contacted mutually, be set as the first metal gear contact chip and the second metal gear contact chip, wherein, first metal gear contact chip comprises the discrete sub-copper brush sheet of m sheet, m be greater than 1 integer, and every slice, thin piece copper brush sheet is connected with the second metal gear contact chip by the resistance of different resistance.When the difference sub-copper brush sheet of brush on the first metal gear contact chip moves, the resistance be connected with the second metal gear contact chip due to each sub-copper brush sheet is different, the signal of telecommunication of gained is different, and potentiometer can be made thus can to obtain different some position signals.
Further, pcb board is circular pcb board.Circular pcb board can save the area of potentiometer base plate, makes price more cheap.
Further, also comprise: be used to indicate the LED that described brush contacts with different described metal gear contact chips.When brush contacts with different metal gear contact chips, the output signal value of potentiometer is different, can multiple LED be set according to different output signal values, be used to refer to the output signal of potentiometer, as LED and metal gear contact chip one_to_one corresponding, corresponding LED is bright then represents that brush is connected with the contact of corresponding metal gear contact chip, and user can be facilitated to learn the adjustment state of potentiometer.
In sum, air conditioning for automobiles potentiometer provided by the present invention, each metal gear contact chip is by being positioned at the resistant series of dorsal part, when the brush of metal gear contact chip homonymy switches mobile between each metal gear contact chip, resistance then between the metal gear contact chip at two ends and brush will change, thus produces different signals.Because different metal gear contact chips is connected by the resistance of dorsal part, the resistance of default resistance can be set as required.When making, only need at the side fixing metal gear contact chip of potentiometer base plate, at dorsal part fixed resistance, to substitute the high resistive element directly contacted with brush of price in existing potentiometer, and resistance is connected with the metal gear contact chip of each correspondence, make simple, cheap, the problem that potentiometer is expensive and procurement cycle is long can be solved.
Above a kind of air conditioning for automobiles potentiometer provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and execution mode, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection range of the claims in the present invention.
