Abstract
The utility model discloses a clock spring for an automobile, which comprises a shell, a lower cover and a return ring arranged between the shell and the lower cover. A roller frame assembly and an inserting needle are also arranged on the lower cover; and an elastic fit key of the clock spring, which is matched with a matching slot of a steering wheel, is arranged on the return ring. The utility model has the beneficial effect that as the clock spring is elastically matched with the steering wheel through the structure of elastic key slot and key, the clock spring overcomes the quality defects of hard assembly damage, clearance, noise and the like of the existing clock spring. The clock spring is simple in structure, is good in stability and is low in cost.
Description
Technical field
The utility model relates to a kind of clock spring, especially relates to a kind of automobile clock spring.
Background technology
Automobile clock spring is to be used for the rotary connector that safe automobile air bag detonates, and is installed in the steering wheel rotating shaft.Vehicle steering will drive clock spring and rotate when rotating; It adopts key to cooperate with groove between the two usually; The fit dimension gap of key and groove is owing to receive ambient temperature; The injection moulding pressure in production process, factor affecting dimensional tolerances such as dwell time, being prone to cause when damage parts not in place or the rotation of fit clearance general orientation dish are installed has play and noise to produce.
The utility model content
The purpose of the utility model provides a kind of automobile clock spring, and is big to solve clock spring and steering wheel fit clearance dimensional tolerance, and existing keyway cooperates not good problem.
The utility model solves the technical scheme that its technical problem adopted: a kind of automobile clock spring, comprise shell and lower cover and be located at shell and lower cover between the return circle, cover under described and also be provided with turning rolls assembly and contact pin; On described return circle, be provided with the clock spring resilient engagement key suitable with the steering wheel mating groove.
Preferably, the described clock spring resilient engagement key resilient clip structure that is umbrella.
Preferably, described steering wheel mating groove is a U type groove.
The beneficial effect of the utility model: realize resilient engagement because clock spring and steering wheel cooperate through the elasticity keyway arrangements.Overcome that clock spring and steering wheel fit clearance scale error were big in the past, cause mass defects such as hard assembling damage, play and noise.And this utility model is simple in structure, good stability, and cost is low.
Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the utility model automobile clock spring organigram.
Fig. 2 is an A place enlarged diagram among Fig. 1.
Among the figure: 1. shell, 2. switch block, 3. first contact pin, 4. lock pin, 5. flexible cable, 6. turning rolls assembly, 7. return circle, 8. lower cover, 9. second contact pin, 10. clock spring resilient engagement key, 11. resilient engagement key tops, 12. resilient clips, 13. steering wheel mating groove bodies, 14. steering wheel mating grooves.
Embodiment
As depicted in figs. 1 and 2, a kind of automobile clock spring, comprise shell 1 and lower cover 8 and be located at shell 1 and lower cover 8 between return circle 7; On described lower cover 8, be provided with turning rolls assembly 6; On described shell 1, be provided with the lock pin 4 that cooperates with steering wheel; Downside at described lower cover 8 is provided with second contact pin 9 that plugs with the loudspeaker wiring harness connector; Upside at described lower cover 8 is provided with first contact pin 3 that plugs with the air bag wiring harness connector, and described two contact pins are connected with wire harness on the return circle through flexible cable 5.
In order to solve clock spring and steering wheel fit clearance dimensional tolerance is big; Existing keyway cooperates the mass defect that has play and noise to produce when being prone to damage parts not in place or the rotation of fit clearance general orientation dish are installed; Be designed to the elasticity keyway arrangements in clock spring and steering wheel cooperation place and match, promptly be provided with the clock spring resilient engagement key 10 suitable on the return circle 7 in switch block 2 with steering wheel mating groove 14.The resilient engagement key top 11 of described clock spring resilient engagement key 10 is a umbrella-shaped structure, is provided with resilient clip at resilient engagement key top 11.On the steering wheel mating groove body 13 of steering wheel, be provided with steering wheel mating groove 14, described steering wheel mating groove is a U type groove.
When being coupled to clock spring on the steering wheel, the resilient clip structure at its clock spring fit key top begins compression, and has made it the pretension cooperation.Guarantee that the steering wheel installation can not damage clock spring, eliminates the noise that both cooperate play to produce simultaneously again.
In the utility model, clock spring and steering wheel cooperate through the elasticity keyway arrangements realizes resilient engagement.Overcome that clock spring and steering wheel fit clearance scale error were big in the past, cause mass defects such as hard assembling damage, play and noise.
Claims (3)
