Abstract
The utility model discloses an ignition lock and steering tubular column fixing anti-theft structure of a car, which is used for locking a steering shaft at the shut-down state of the car so as to realize the anti-theft function of the car; the structure comprises an ignition lock assembly, a steering tubular column shell, an ignition lock fixing clamp and a bolt component, and is characterized in that the left and right sides of the steering tubular column shell are provided symmetrically with reinforcement ribs, and the parts of the ignition lock fixing clamp, corresponding to the reinforcement ribs on the steering tubular column shell, are provided with escaping openings. According to the utility model, the size and weight of the steering tubular column shell are reduced, the development cost and production cost are reduced, and meanwhile, the phenomenon of stress concentration on the transition position between the original auricular connection base and the edge of the shell is eliminated.
Description
Technical field
The utility model relates to a kind of automotive ignition locking fixed structure, is particularly useful for being realized by ignition lock and steering column combination the fixed sturcture of automobile burglar function, belongs to automobile technical field.
Background technology
Vehicle suppresses the rotation of steering shaft through the combination of steering column and ignition lock under flameout state, with this locking of realizing steering swivel system, reach the antitheft purpose.The steering column that has anti-theft feature is provided with dead bolt with the ignition lock cooperation place square groove being set on the ignition lock assembly, and dead bolt passes square groove, embeds in the hold down groove that is provided with on the steering shaft.When torsional interaction is on bearing circle outside powerful, can cause the square groove cracking of steering column, ignition lock rotates in company with steering shaft, causes the forfeiture of automobile burglar function.To above-mentioned situation, people improve the steering column structure, share the shearing force at steering column square groove place through on steering column, arranging ignition lock " ear shape " Connection Block; But because overall dimensions is bigger, parts weight increases, and it is complicated to make mould process; Time-to-market is long; To casting mould tonnage demand height, improved the exploitation and the manufacturing cost of steering column, and also can produce stress concentration at " ear shape " Connection Block and shell rim transition junction.
The utility model content
The purpose of the utility model is the drawback to prior art, a kind of simple in structure, dependable performance is provided, can reduces own wt, and the car steering tube column ignition lock of guaranteeing the steering column anti-theft feature is theft-prevention structure fixedly.
The said problem of the utility model realizes with following technical proposals:
A kind of car steering tube column ignition lock is theft-prevention structure fixedly; It comprises ignition lock assembly, steering column housing, ignition lock fixation clamp and bolt assembly in constituting; Its special feature is: the said steering column housing left and right sides is symmetrical set reinforced rib, and said ignition lock fixation clamp is being dodged mouth with the setting of steering column casing bracing muscle corresponding position.
Above-mentioned car steering tube column ignition lock is theft-prevention structure fixedly, and said steering column housing is provided with square lock-tongue port at fixed ignition lock assembly one side center position.
Above-mentioned car steering tube column ignition lock is theft-prevention structure fixedly, and said ignition lock assembly fixed end is the halfliner structure, is provided with the dead bolt of protrusion in the center of this halfliner structure, the lock-tongue port coupling of said dead bolt and steering column housing.
Above-mentioned car steering tube column ignition lock is theft-prevention structure fixedly, and said ignition lock fixation clamp is and ignition lock assembly fixed end halfliner symmetrical structure.
Above-mentioned car steering tube column ignition lock is theft-prevention structure fixedly, and the halfliner structure and the ignition lock fixation clamp of said ignition lock assembly fixed end are fixed together through bolt assembly, are sleeved on the outside of steering column housing.
The utility model is provided with reinforced rib on the steering column housing, ignition lock assembly fixed end and ignition lock fixation clamp bolt up are held the steering column housing tightly; There is not torsional direction dish under the ignition lock key situation; The stressed generation rotation of ignition lock trend is rotated through lock-tongue port and reinforced rib restriction ignition lock, and wherein two reinforced ribs play and share shear action; Avoid lock-tongue port to produce stress concentration and ftracture, played the antitheft effect.The utility model has reduced the size and the weight of steering column housing, has reduced exploitation and manufacturing cost, has eliminated former " ear shape " structure Connection Block and shell rim transition position stress concentration phenomenon simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the constructional drawing of the utility model;
