Product Knowledge

The use of power springs in automobiles is primarily associated with various mechanical systems and components that require the storage and release of mechanical energy. Power springs, also known as clock springs or spiral springs, are coiled springs that store potential energy when wound up and release it gradually as they unwind.

1. Steering Systems: Power springs are utilized in the steering column to enable the rotation of the steering wheel while maintaining electrical connections for components such as the horn, airbag, and other steering controls.

2. Airbag Systems: Power springs are crucial components in airbag systems. They provide a reliable electrical connection between the vehicle's electrical system and the airbag module, allowing for continuous communication and readiness.

3. Seat Belt Systems: Power springs are employed in retractors within seat belt systems. They facilitate the automatic retraction of the seat belt webbing, ensuring it remains properly stowed when not in use and enabling easy extension for occupant restraint.

4. Audio and Lighting Controls: Power springs can be found in control mechanisms for audio volume adjustment, lighting controls (such as turn signal switches), and other electrical devices in the vehicle's interior.

5. Wipers and Washers: Power springs play a role in windshield wiper and washer systems. They enable the automatic return of wiper blades to their resting position and assist in controlling the pressure applied to the windshield during operation.

6.Steering Wheel Controls: Power springs are used in the wiring mechanisms of steering wheel-mounted controls, such as audio controls, cruise control, and other driver assistance features.
