Description
Technical field
The utility model relates to automobile technical field, relates in particular to a kind of automobile instrument stepping motor with potentiometer.
Background technology
Along with electronic information technology in all fields industry-by-industry develop rapidly with and extensive use, the digitlization of instrument, intellectuality are also being quickened, the Hyundai Motor instrument is experiencing the analog circuit electronic type and is making the transition to the stepping electrodynamic type.The core of stepping electrodynamic type automobile instrument is controlled to be stepping motor; Stepping motor is through pulse controlled stepping electric device; When stepping motor receives a pulse signal, it is with regard to drive motors rotational fixation angle, thus driving automobile gauge pointer rotational fixation angle.
The automobile instrument stepping motor is owing to reasons such as self and institute's bringing onto load inertia, resonance, power down suddenly, and motor may produce step-out in the long-term operation process.Though a lot of outstanding motor for instrument driven algorithm are arranged at present, but can not solve the step-out problem at all.At present, addressing this problem usual method is: when the firm speed of ignition of vehicle was zero, controller control step motor rotated a fixed angle X1, and pointer is made zero.But the deviation angle X2 (as shown in Figure 1) during owing to light a fire between unknown pointer position 100 ' and the zero velocity point 200 '; And this fixed angle of will guaranteeing to make zero will be chosen suitable (guaranteeing that X1 is greater than X2), so in the process of making zero, often there is a stall angle X3=X1-X2.Like this, vehicle exists pointer vibration, noise when the startup gauge pointer makes zero, and influences the life-span of instrument stepping motor simultaneously greatly.
The utility model content
The purpose of the utility model is; A kind of automobile instrument stepping motor with potentiometer is provided; Stall problem when it can solve the automotive ignition instrument and makes zero is eliminated and is overcome the instrument defective that life-span of gauge pointer vibration in the process, noise, stepping motor reduces that makes zero.
To achieve these goals; The utility model provides a kind of automobile instrument stepping motor with potentiometer; It comprises: stepping motor and be located at the rotary type potentiometer on the stepping motor; This rotary type potentiometer is located at the rotation axis that is used for the Control of Automobile gauge pointer of stepping motor, this rotary type potentiometer have resistive element and be located on the resistive element and with the moving contact of stepping motor rotation axis interlock.
Be respectively equipped with the control pin on the said rotary type potentiometer and gather the pin correspondence and be connected with resistive element both ends and moving contact end.
The beneficial effect of the utility model: the utility model provides a kind of automobile instrument stepping motor with potentiometer; Stall problem when it can solve the automotive ignition instrument and makes zero is eliminated and is overcome the instrument defective that life-span of gauge pointer vibration in the process, noise, stepping motor reduces that makes zero.
In order further to understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited about the utility model.
Description of drawings
Below in conjunction with accompanying drawing, describe in detail through embodiment the utility model, the technical scheme that makes the utility model and other beneficial effect is obvious.
In the accompanying drawing,
The principle schematic that Fig. 1 makes zero for existing automobile meter pointer;
Fig. 2 is the structural representation of the automobile instrument stepping motor of the utility model band potentiometer.
Embodiment
For further setting forth technological means and the effect thereof that the utility model is taked, be described in detail below in conjunction with the preferred embodiment and the accompanying drawing thereof of the utility model.
As shown in Figure 2; The utility model provides a kind of automobile instrument stepping motor with potentiometer; It comprises: stepping motor 10 and be located at the rotary type potentiometer 20 on the stepping motor 10; This rotary type potentiometer 20 is located at the rotation axis that is used for the Control of Automobile gauge pointer 12 of stepping motor 10, this rotary type potentiometer 20 have resistive element and be located on the resistive element and with the moving contact of stepping motor rotation axis interlock.
Further; Be respectively equipped with control pin 22 on this rotary type potentiometer 20 and gather pin 24 correspondences and be connected with resistive element both ends and moving contact end; Can add voltage through control pin 22, and after moving contact changes the position on resistive element and gather the magnitude of voltage of variations gathering pin 24; In the utility model, this rotary type potentiometer 20 can adopt existing design, comprises that a resistive element and rotates or sliding system as the one of which, and more precisely potentiometer is to have the resistive element that three exits, resistance can be regulated by certain Changing Pattern; In the utility model; The rotation axis of stepping motor 10 is movable with the control moving contact as the rotation system of rotary type potentiometer, and when the rotation axis 12 of stepping motor 10 rotated, moving contact also changed the position on resistive element; Thereby; Resistance value between the two pins at the pin of moving contact end and resistive element two ends all changes, and is certain functional relation between the anglec of rotation of this variation and stepping motor 10, can be according to the concrete parameter of rotary type potentiometer and calculate acquisition through known formula; Therefore the deviation angle of pointer is known angle when control is made zero, and has so just solved the stall defective when making zero.
In sum, the utility model provides a kind of pointer of automobile instrument method that makes zero, and the stall problem when it can solve the automotive ignition instrument and makes zero is eliminated and overcome the instrument defective that life-span of gauge pointer vibration in the process, noise, stepping motor reduces that makes zero.
The above; For the person of ordinary skill of the art; Can make other various corresponding changes and distortion according to the technical scheme and the technical conceive of the utility model, and all these changes and distortion all should belong to the protection range of the utility model claim.
