Description

Technical Field

[0001] The utility model relates to the field of accelerator pedals, in particular to an accelerator pedal sensor for a farm vehicle. Background Technique

[0002] The accelerator pedal sensor of a farm vehicle is an important part of the electronic control system of the farm vehicle. It is used to detect the degree to which the driver steps on the accelerator pedal and convert this information into an electrical signal to be transmitted to the engine control unit (ECU), thereby achieving precise control of the engine output power. Currently, traditional accelerator pedal sensors mainly consist of a housing, an internal control board, and a strong magnetic component linked to the accelerator pedal. The strong magnetic component is linked to the accelerator pedal to transmit the position change signal of the accelerator pedal to the control board. However, currently, the strong magnet is generally glued to the surface of the rotating seat. After being used for a period of time, the strong magnet is likely to fall off, thus affecting the normal use of the sensor. Therefore, the existing technology has the problem that the strong magnet is likely to fall off. Content of the Utility Model

[0003] The purpose of the utility model is to provide an accelerator pedal sensor for a farm vehicle. The utility model has the characteristic of being able to improve the installation stability of the strong magnet.

[0004] The technical solution of the utility model: An accelerator pedal sensor for a farm vehicle includes a base. A control main board is arranged inside the base. A Hall effect sensor is arranged on the control main board. The control main board is connected with a wire harness and a connector. A face cover is arranged above the base. A cavity is arranged inside the lower part of the base. A strong magnet rotating seat is arranged inside the cavity. A strong magnet is arranged inside the strong magnet rotating seat. A rotating seat cover plate is arranged outside the strong magnet rotating seat. A strong magnet installation cavity for installing the strong magnet is arranged inside the strong magnet rotating seat. Limit buckles are arranged on both sides of the strong magnet installation cavity.

[0005] In the aforementioned accelerator pedal sensor for a farm vehicle, a rotating limit post activity groove is arranged inside the cavity. A rotating start limit surface and a rotating end limit surface are respectively arranged at both ends of the rotating limit post activity groove.

[0006] In the aforementioned accelerator pedal sensor for a farm vehicle, a rotating limit post is arranged on the chassis of the strong magnet rotating seat.

[0007] In the aforementioned accelerator pedal sensor for a farm vehicle, a clamping groove is arranged on the outer wall surface of the rotating seat cover plate.

[0008] Compared with the prior art, by arranging a strong magnet installation cavity inside the strong magnet rotating seat and arranging two symmetrically distributed limit buckles in the utility model, the strong magnet installed in the strong magnet installation cavity is stable and reliable, effectively reducing the risk of the strong magnet falling off and ensuring the stable and reliable use of the sensor. In summary, the utility model has the characteristic of being able to improve the installation stability of the strong magnet. Description of the Drawings
