Description

Technical Field

[0001] This utility model relates to the field of clock spring mounting technology, and in particular to a clock spring mounting and positioning structure. Background Technology

[0002] Clock springs are used for the electrical rotational connection between automotive steering wheel airbags and their control systems. They are typically installed below the steering wheel, on the combination switch base, or above the steering column tray. Clock springs generally have a base, with a housing covering the base to form a stator mechanism. A faceplate is installed on the upper part of the housing, and a pull block is installed at the lower end of the base. The faceplate and pull block, or the faceplate, sliding element, and pull block, are fastened together to form a rotation mechanism. The stator mechanism and the rotation mechanism cooperate to form an internal cavity. A rotating wheel frame mechanism with rollers or an elastic belt structure is installed within the cavity to form a drive device, allowing the cables within the cavity to rotate freely.

[0003] In the existing technology, there are usually two ways to install clock springs: screw fastening or elastic snap-fit. Screw fastening increases the operation steps and is inconvenient to install. At present, elastic snap-fit ​​is the mainstream method.

[0004] The main problem with the elastic snap-fit ​​connection of clock springs to the base is that the snap-fit ​​size is difficult to control. In the axial direction, it is easy to cause the snap-fit ​​to loosen or fail to overlap. In the radial direction, the clock spring cannot be guaranteed to fit tightly with the base after installation, resulting in the clock spring shaking or failure to assemble, which affects the driving experience and the life of the clock spring. Therefore, this utility model proposes a clock spring installation and positioning structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the main problems of existing clock springs connected to the base by elastic snap-fit, which are difficult to control in terms of snap-fit ​​size, easily causing loosening or failure to overlap in the axial direction; and in the radial direction, the clock spring cannot be guaranteed to fit tightly with the base after installation, resulting in overall clock spring wobbling or inability to assemble, which affects the driving experience and the lifespan of the clock spring. Therefore, this invention proposes a clock spring installation and positioning structure.

[0019] As a preferred scheme of the utility model, the side, where the two clamps are close to each other, is fixedly installed with a protective pad. Beneficial effects

[0020] After the two control frames are close to each other, the two control frames can squeeze the four fitting rods to be close to each other, so that the four fitting rods can drive the two clamps to be close to each other, so that the two clamps can be fitted with the clock spring, and the fitting frame can be moved in the process of moving the clamp, and the fitting frame will be pulled down by the pulling rod to be fitted with the top of the clock spring to clamp the clock spring.

[0021] When the four fitting rods drive the two clamps to move close to each other, the four sliding rods will slide at the bottom of the four sliding rods, and the adjacent two sliding rods will move close to each other at the top of the control frame at the current position, and after the positioning frame engages with the sliding rod, the positioning frame can block the movement of the sliding rod on the control frame, so that the positioning of the sliding rod is realized, and the sliding rod cannot slide at the top of the control frame, so that the fitting rod cannot drive the clamp to move, and the positioning of the clamp is realized, and the clamp can position the position of the fitting frame, so that the clock spring can be stably installed.
