Description

Technical Field

[0001] The utility model relates to the technical field of position sensors, in particular to a position sensor component. Background Art

[0002] The accelerator pedal position sensor is an indispensable component of the automotive electronic throttle system. The accelerator pedal position sensor is a sensor used to detect changes in the accelerator pedal position. It measures the depth (or angle) of the accelerator pedal and converts these changes into electrical signals to achieve precise control of the engine power output. There are two main types of accelerator pedal position sensors: sliding resistor type and contactless Hall type. The sliding resistor type generates a signal by changing the resistance value, while the contactless Hall type uses the Hall effect to detect changes in the magnetic field and generate a signal.

[0003] Usually, the position sensor is connected to the accelerator pedal interface with a single snap-on connection, which has no protective effect. This makes it easy for the sensor to become loose due to external force, and it is easy for external water vapor to penetrate and corrode the surface of the sensor, resulting in reduced sensor sensing effect or insensitive use. Therefore, we have proposed a position sensor assembly to solve the above problems. Utility Model Content
