Abstract

The invention discloses a protection mechanism for a fan of an automobile cooling box, and relates to the technical field of fan protection; in order to solve the problem of motor overload operation; it specifically includes a cross-shaped fixing rod and a first fan plate, and the outer wall on one side of the cross-shaped fixing rod An elastic fixing ring is provided, an insulation board is arranged on the outer wall of one side of the elastic fixing ring, and a condensation plate is arranged on the outer wall of the insulation board far away from the elastic fixing ring. The invention is equipped with a wind speed sensor to detect the rotation speed of the external fan blade, and transmits the detected speed to the controller, the controller is connected to the external motor, and the controller determines whether the fan blade rotation speed is normal after data processing , so as to determine whether the motor is in the state of overload operation. If the motor is in the state of overload operation, the controller will alarm to remind the user of the operation state of the motor at this time, and cut off the power of the motor to prevent the motor from being in the state of overload operation for a long time, which will affect the motor. service life.

Description

technical field [0001] The invention relates to the technical field of fan protection, in particular to a protection mechanism for an automobile radiator fan. Background technique [0002] The car radiator is a heat dissipation device used to dissipate the heat generated during the operation of the car. There are fans on the car radiator. These fans need to use a protective mechanism for the car radiator fan during operation. Prevent the fan blade from pinching the user during operation, but most of the existing fan protection mechanisms do not have the function of detecting the relationship between the wind speed of the fan blade and the motor speed. During the operation of the motor, damage to the fan blade or Unable to run, resulting in the phenomenon of motor idling, which seriously affects the service life of the motor. [0003] After searching, the Chinese patent application number is CN210680382U, which discloses a truck water tank soft connection fan guard, includin...
