The system employs an elastic pressing mechanism and a guiding assembly mechanism. The slide rod is slidably connected by the first and second sliding sleeves, and the second spring provides downward pressure to the pressure block, thereby achieving a tight connection between the spring sheet and the connecting spring sheet and increasing the reliability of the connection.
This improves the tightness of the spring and connecting spring, reduces the possibility of broken contact between the spring and connecting spring after long-term use, and ensures the stability and reliability of the connection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a spring-loaded fan controller. Background Technology
[0002] Currently, automotive air conditioning systems require brushed fan controllers, which are devices used to control the operation of brushed fans. Brushed fan controllers primarily control the direction and magnitude of the motor's current to achieve forward and reverse rotation and speed regulation. When the controller is powered on, it generates a PWM (Pulse Width Modulation) signal. The frequency and duty cycle of this signal can be changed by adjusting potentiometers, etc. There are many types of brushed fan controllers available, including spring-loaded fan controllers.
[0003] The existing spring-type fan controller has the following problems when in use: it usually relies on the elasticity of its own spring to press the connecting spring to connect. That is, one end of a single spring presses against the connecting spring of the brushed fan, and the other end of the single spring presses against the connecting spring of the controller to realize the connection between the brushed fan control end and the controller. Since the pressing mainly relies on the elasticity of its own spring, after a long period of insertion and removal, the elasticity of its own spring decreases, which can easily cause the connection between the spring and the connecting spring to break.
