Description

Technical Field

[0001] This utility model relates to the field of electronic actuator technology, and in particular to an electronic actuator voltage calibration device in a turbocharger. Background Technology

[0002] A turbocharger is a device that improves the intake efficiency of an engine by compressing air, while an electronic actuator is an electromechanical device used to control the exhaust bypass valve inside the turbocharger.

[0003] When the exhaust valve in the turbocharger is at any angle, the electronic actuator will output a corresponding voltage. Therefore, the turbocharger needs to undergo static voltage calibration before it is manufactured and shipped to determine whether the voltage signal output by the electronic actuator when the exhaust valve is fully closed is within a predetermined range. If there is a voltage deviation, the operator can adjust the voltage by adjusting the length of the push rod. Currently, the process of performing the above voltage calibration is relatively complicated. Therefore, a voltage calibration device needs to be designed to perform the calibration work quickly and conveniently. Utility Model Content

[0023] Reference Figures 1-2 According to an embodiment of the electronic actuator voltage calibration device in a turbocharger, the present invention includes a housing 11, wherein the housing 11 is provided with a motor drive module, a power supply module and a voltage measurement module;

[0024] When the electronic actuator voltage calibration device in the turbocharger is connected to the electronic actuator, the motor drive module is used to drive and control the motor in the electronic actuator that controls the turbocharger exhaust valve. The motor drive module includes an adjustable switching power supply. The input terminal of the adjustable switching power supply is connected to 220V AC. The DC output terminal of the adjustable switching power supply is connected to a motor drive line through a forward / reverse switch. There are two motor drive lines, which can be connected to the positive and negative terminals of the DC motor in the electronic actuator, respectively.

[0025] That is, the operator can rotate the adjustable knob in the adjustable power supply to control its output voltage and adapt it to the motor in the electronic actuator. After the connection is completed, the operator can rotate the forward and reverse switch to drive the switch in the electronic actuator to rotate forward and reverse, thereby making the exhaust valve in the turbocharger fully open or fully closed.

[0026] The power supply module is used to power the MCU in the electronic actuator. The power supply module includes an AC-DC module. The input terminal of the AC-DC module is connected to 220V AC. The output terminal of the AC-DC module is connected to the actuator power supply line. The actuator power supply line has two polarities, positive and negative, and can be connected to the MCU and ground wire in the electronic actuator respectively.

[0027] The voltage measurement module includes a voltmeter, and the power supply module is also used to supply power to the voltmeter. Specifically, the actuator power supply line is also connected to the positive and negative terminals of the voltmeter to supply power to the voltmeter. The voltmeter is also connected to a signal line, which can be connected to the signal output terminal of the electronic actuator so that the voltmeter displays the voltage output by the electronic actuator.

[0028] First, it needs to be clarified that the electronic actuator is fixed on the turbocharger, and the output shaft of the motor inside the turbocharger controls the opening of the exhaust valve inside the turbocharger through a push rod. The voltage signal output by the electronic actuator is different for the exhaust valve inside the turbocharger at any angle.

[0029] Overall voltage calibration process:

[0030] The motor drive line, the actuator power supply line, and the signal line are all connected to the connector. The connector is adapted to the socket inside the electronic actuator. The connection is completed when the operator inserts the connector into the socket inside the electronic actuator and connects the electronic actuator voltage calibration device in the turbocharger to 220V AC.

[0031] Afterwards, the operator can rotate the forward and reverse switch to drive the motor in the electronic actuator to drive the exhaust valve in the turbocharger to the fully closed state. At this time, the output voltage signal in the electronic actuator is displayed by the voltmeter. The operator can observe whether the voltage value displayed by the voltmeter is within the preset range to determine whether the turbocharger is qualified.

[0032] If the voltage is not within the preset range when the exhaust valve is fully closed, the operator can adjust the length of the push rod and adjust the turbocharger. This is existing technology and will not be described in detail here.

[0033] Furthermore, in this embodiment, the adjustable switching power supply has an adjustment range of 3-12V, and the output voltage of the AC-DC module is 5V.

[0034] Furthermore, the adjustable switching power supply is fixed to the rear side of the housing 11, with the adjustable knob inside the adjustable switching power supply facing rearward, the voltmeter placed inside the housing 11, with the display screen inside the voltmeter facing upward, and the forward / reverse switch installed facing forward.

[0035] It should be noted that the voltmeter is an unconventional selection. The function of the voltmeter is to receive power from the power supply module and to display the voltage signal transmitted from the electronic actuator.

[0036] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
