Abstract
The utility model discloses a detecting device of the air damper position sensor used for detecting the air damper position sensor of the automobile engine electronic control system, wherein, the detecting device comprises a voltage stabilized power supply (9), an ammeter (10), a shaft core rotating device (13), and an air damper position sensor (8). The shaft core rotating device comprises a machine seat (3), a hand handle (4) and a simulate air damper shaft (2). The machine seat is rotationally connected with the simulate air damper shaft which is provided with a hand handle. One end of the simulate air damper shaft is sleeved with the air damper position sensor. One end of the ammeter is connected with the output end of the air damper position sensor and the other end thereof is connected with the voltage stabilized power supply. Through the detecting device, whether the air damper position sensor is qualified can be detected, which resolves the problem of low percent of pass of the produced sensor influencing the safe function of automobiles.
Description
[technical field]
The utility model relates to a kind of pick-up unit of sensor, what be specifically related to is a kind of pick-up unit of car engine electronic control system throttle position sensor.
[background technology]
Along with motor car engine emission standard day by day strictness and energy savings reduce the needs that consume, motor car engine generally adopts electronic control means.When vehicle starting or acceleration, air throttle is opened rapidly, air pressure probe or airflow measuring device are with the recruitment of air in the inlet manifold, mode with current signal passes to ECU (Electrical Control Unit), but to sending instruction there is a mistiming that relatively lags behind from received signal, gasoline can not in time promptly be provided, thereby influence engine capacity output.Therefore in Motronic control maps control fuel injection system, use throttle position sensor to address this problem preferably.This throttle position sensor comprises that sensor turning axle, armature contact, throttle sensor body, output are participated, potentiometer; Sensor turning axle and throttle sensor body are rotationally connected, potentiometer is installed the throttle sensor body and output is participated, and potentiometer is participated with output and is connected, and output is participated with plug connector and pegged graft, be connected with armature contact on the sensor turning axle, armature contact can paste potentiometer and move.Pick-up unit is that exploitation and production throttle position sensor must indispensable equipment, but does not also have a kind of this throttle position sensor pick-up unit to put into production at present and use, and makes that the sensor qualification rate of dispatching from the factory is low, directly influences the safe operation of automobile.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is in order to solve the detection problem of throttle position sensor, a kind of like this throttle position sensor pick-up unit to be provided.
The utility model is realized as follows, a kind of pick-up unit of throttle position sensor, it is characterized in that described pick-up unit comprises stabilized voltage supply, ammeter, axle core whirligig, throttle position sensor, described axle core whirligig comprises support, handle, simulation throttle plate pin, described support and described simulation throttle plate pin are rotationally connected, on the simulation throttle plate pin handle is installed, one end socket throttle position sensor of simulation throttle plate pin, one end of described ammeter is connected with the output terminal of throttle position sensor, and the other end is connected with stabilized voltage supply.Work as turning handle, the simulation throttle plate pin rotates thereupon, and air throttle sensor resistance value is changed, and its output voltage changes thereupon, and the ammeter display voltage judges whether this throttle sensor is qualified.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structure principle chart of the present utility model
Fig. 2 is the structural drawing of the utility model axle core whirligig and throttle position sensor
[embodiment]
A kind of pick-up unit of throttle position sensor, comprise stabilized voltage supply 9, voltage table 10, plug connector 7, axle core whirligig 13, throttle position sensor 8, described axle core whirligig comprises support 3, handle 4, simulation throttle plate pin 2, described support and described simulation throttle plate pin are rotationally connected, on the simulation throttle plate pin handle is installed, support one side fluting, handle can rotate in groove; One end socket throttle position sensor of simulation throttle plate pin, throttle position sensor and plug connector are pegged graft, and participate a, the b of plug connector are connected by circuit with the two poles of the earth of stabilized voltage supply respectively, participate c, b and are connected by circuit with the output terminal of voltage table respectively; Stabilized voltage supply provides the stable dc power supply of 5V, the practical power environment of simulation throttle position sensor; Throttle position sensor comprises that sensor turning axle 1, armature contact 5, throttle position sensor body 6, output participate 11, potentiometer 12; Sensor turning axle and throttle position sensor body are rotationally connected, potentiometer is installed the throttle position sensor body and output is participated, potentiometer is participated with output and is connected, output is participated with plug connector 7 and is pegged graft, be connected with armature contact on the sensor turning axle, armature contact can paste potentiometer and move.When detecting throttle sensor, throttle position sensor is enclosed within on the simulation throttle plate pin, turning handle, the simulation throttle plate pin rotates thereupon, drives the sensor turning axle and rotates, the armature contact that is fixed on the sensor turning axle rotates thereupon, change the resistance value of potentiometer, the throttle position sensor resistance value is changed, its output voltage changes thereupon, the voltage table display voltage judges by the situation of change of shown voltage whether this throttle position sensor is qualified.Turning handle, the equidirectional linear change of voltage table display voltage illustrates that this throttle position sensor is qualified, if the undesired variation of voltage table display voltage illustrates that then this throttle position sensor is defective.By a kind of like this pick-up unit, just can detect throttle position sensor.
