Description

Technical Field

[0001] The utility model belongs to the field of automobile accessories, and in particular relates to a clock spring with a temperature control function for a steering wheel. Background Art

[0002] The clock spring connects the main airbag (the one on the steering wheel) to the airbag wiring harness, essentially a length of wiring. Because the main airbag rotates with the steering wheel (think of it as a certain length of wiring wrapped around the steering shaft, which can be loosened or tightened as the steering wheel rotates), there needs to be enough room in the wiring harness to ensure it can be turned to the extremes of the steering wheel without breaking.

[0003] However, the existing clock spring with temperature control function for steering wheels is assembled from multiple parts, which makes it inconvenient to disassemble and repair the clock spring when it fails later.

[0004] Therefore, it is very necessary to invent a clock spring with a temperature control function for a steering wheel. Utility Model Content

[0024] The surface of the sleeve 3 is evenly distributed with a number of holes 31 corresponding to the barbed claws 23, and the barbed claws 23 are clamped in the corresponding holes 31 to prevent the stator housing 1 and the rotor cover 2 from being separated during use. The sleeve 3 is detachably mounted on the bottom of the stator housing 1.

[0025] The airbag wiring harness 4 and the steering wheel heating temperature control wiring harness 5 are rotatably wound on the shaft sleeve 3 so that the airbag wiring harness 4 and the steering wheel heating temperature control wiring harness 5 rotate along with the shaft sleeve 3 .
