Technical field
The utility model relates to field of automobile, the automatic control tegulatingdevice of specific design motor car engine throttle.
Background technique
Motor vehicle exhaust emission detection, the test of air-conditioning ring mould, road roller etc. need its engine speed of control, make it in different rotating speeds work.Detect as double idle and the discharging of simple and easy condition tail gas.Need artificial accelerator pedal control engine speed, it is worked under the rotating speed of regulation.But the automatic control tegulatingdevice that present motor car engine throttle is equipped with is to integrate with car load, and is non-dismountable, can not use separately, and have only a small amount of automobile that above-mentioned integrated automatic control tegulatingdevice is housed.And up-to-date automobile relevant laws and regulations require vehicle will have the standard interface that is used for fault diagnosis, it is the OBD diagnose interface, can obtain power supply and obtain the relevant information of vehicle by this interface, be used for control, can accomplish plug and play by its communication function that provides.In order to make the existing automobile of automatic control tegulatingdevice that is not equipped with also possess the function that engine throttle detects automatically, a kind of automatic control tegulatingdevice of motor car engine throttle need be provided, enable to be loaded in directly, easily on the automobile, realize the function that engine throttle detects automatically.
The model utility content
For making the automobile of not being furnished with the automatic measuring ability of engine throttle also possess the function that throttle detects automatically, the utility model provides the automatic control tegulatingdevice of motor car engine throttle, and its concrete structure is:
The automatic control tegulatingdevice of motor car engine throttle is made up of throttle accelerator pedal control unit 1, throttle accelerator pedal driver element 2, drive mechanism 3 and uninterruptable power source 6; Throttle accelerator pedal control unit 1 is connected with an end of throttle accelerator pedal driver element 2, and the other end of throttle accelerator pedal driver element 2 is connected with drive mechanism 3.Uninterruptable power source 6 is connected with drive mechanism 3 with throttle accelerator pedal control unit 1, throttle accelerator pedal driver element 2 respectively, and power supply; Wherein, throttle accelerator pedal control unit 1 sends control command to throttle accelerator pedal driver element 2; The throttle accelerator pedal driver element 2 that receives control command sends drive signal to drive mechanism 3; Drive mechanism 3 is made up of stepper motor 31, connecting rod 32 and sucker-type magnet piece 34, wherein, have on the side of stepper motor 31 can level flexible movable axis 33, fixedly connected with an end of connecting rod 32 in the top of movable axis 33; The bottom of stepper motor (31) is provided with sucker-type magnet piece (34).
The utility model beneficial technical effects is:
By using this device, can carry out easily and fast device upgrade to being unkitted the motor that has the engine throttle monitoring function, realize the effect that detects automatically; After using this product, can realize the automatically controlled engine rotating speed, exempt that manual operation is lack of standardization, inaccuracy, drawback such as when taking a lot of work; The throttle accelerator pedal control unit of this product can be provided with complicated control program, realizes the intelligent control under the complex situations, controls as finishing acceleration, deceleration, speed stabilizing etc. and various mixing by setup program, thereby satisfies more user demands.

Fig. 1 is the utility model working principle skeleton diagram.
Fig. 2 is the schematic diagram of drive mechanism mounting point and motion mode among Fig. 1.
Sequence number among the figure is: throttle accelerator pedal control unit 1, throttle accelerator pedal driver element 2, drive mechanism 3, Engine ECU 4, throttle accelerator pedal 5, uninterruptable power source 6, platform floor 7, stepper motor 31, connecting rod 32, movable axis 33, sucker-type magnet piece 34.
Embodiment
Now describe structural principle of the present utility model in detail in conjunction with Fig. 1 to 2.
The automatic control tegulatingdevice of motor car engine throttle is made up of throttle accelerator pedal control unit 1, throttle accelerator pedal driver element 2, drive mechanism 3 and uninterruptable power source 6; Throttle accelerator pedal control unit 1 is connected with an end of throttle accelerator pedal driver element 2, the other end of throttle accelerator pedal driver element 2 is connected with drive mechanism 3, uninterruptable power source 6 is connected with drive mechanism 3 with throttle accelerator pedal control unit 1, throttle accelerator pedal driver element 2 respectively, and power supply; Wherein, the throttle accelerator pedal control unit 1 that reads after Engine ECU 4 parameters sends control command to throttle accelerator pedal driver element 2; The throttle accelerator pedal driver element 2 that receives control command sends drive signal to drive mechanism 3; Drive mechanism 3 is made up of stepper motor 31, connecting rod 32 and sucker-type magnet piece 34, wherein, have on the side of stepper motor 31 can level flexible movable axis 33, fixedly connected with an end of connecting rod 32 in the top of movable axis 33; The bottom of stepper motor (31) is provided with sucker-type magnet piece (34).
During use, throttle accelerator pedal control unit 1 is connected with the Engine ECU 4 of automobile respectively with uninterruptable power source 6, wherein, throttle accelerator pedal control unit 1 reads the parameter information of Engine ECU 4, and uninterruptable power source 6 is from motor ECU 4 power takings.By sucker-type magnet piece 34 with drive mechanism 3 be fixed on the platform floor 7, near the dead ahead of the throttle accelerator pedal of pilot set one side, movable axis 33 moving direction corresponding with the throttle accelerator pedal, the other end of connecting rod 32 contacts with the throttle accelerator pedal of not trampled under the state.
After throttle accelerator pedal control unit 1 is connected with car load OBD diagnose interface on the Engine ECU 4 by the K line and reads out signals such as the speed of a motor vehicle in the Engine ECU 4, engine speed, stepper motor 31 through throttle accelerator pedal driver element 2 controlling and driving mechanical devices 3 is done fore and aft motion: connecting rod 32 stretches out, when promptly throttle accelerator pedal 5 being applied active force, realize the effect of opening the throttle; The withdrawal of connecting rod 32 promptly reduces throttle accelerator pedal 5 is applied active force, realizes reducing the effect of throttle.
