Present child lock generally includes children's cage knob and children's locking bar, and cage knob can be by being arranged on the door lock base plate that set angle rotates, and an end of locking bar is fixed on cage knob, and the middle control spring of the other end and door lock offsets.During use, the rotation cage knob, can drive and lift on locking bar or fall, thereby control spring in door lock is lifted or falls, and realizes the locking/unlocking function of door lock.Although this structure can realize the locking of child lock, it is merely to rely on the anglec of rotation of children's cage knob to determine whether middle control spring is lifted, the lock construction that unwinds in lock body was lost efficacy.But the anglec of rotation of knob is subject to the size impact of mechanism's resistance, frictional resistance and manual operation power, might not rotate to upper lock position, and whether arrive the operating position without prompting, perhaps be subjected to drag effect that the possibility of resilience is arranged, in time find surely but differ, so reliability is not high, still there is certain potential safety hazard.
Some high-end car has adopted electronic child lock, and safety is relatively high, but the structure relative complex needs electronic control, and cost is higher, and maintenance cost is high, is not suitable for the low and middle-end car and uses.
Summary of the invention
For defective of the prior art, the utility model provides a kind of child lock for automobile of determining the lock position.
For reaching above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of child lock for automobile, comprise cage knob and locking bar, cage knob is arranged in the door lock housing, locking bar one end is fixedly connected with cage knob, the middle control spring of the other end and door lock offsets, and the locking bar that rotarily drives by cage knob lifts the middle control spring of door lock or fall to realize that child lock is locked or release, and it also comprises a safety spring, one end of safety spring is connected with door lock housing lower end, and the other end is connected with cage knob.
The utility model also can further be realized by the following technical programs:
Described child lock for automobile, wherein, described cage knob is arranged on the side of door lock housing, is comprised of integrated drive block, quadrant block and operating block; Quadrant block is between drive block and operating block, and the operating block top is provided with the moving lock stop block, and the outside is provided with operating groove, and drive block is provided with two blocks; Described locking bar is arranged on the door lock enclosure interior, and by locking rod section, laterally connecting rod section and control lever section three parts form, locking rod section is connected between two blocks of cage knob drive block, and the middle control spring of control lever section and door lock offsets.
Described child lock for automobile, wherein, described safety spring is torsion spring, and an end of torsion spring is hook-shaped reverse arm, and an end is the right angle reverse arm, and hook-shaped reverse arm end hook is in door lock housing lower end, and right angle reverse arm end is connected with the cage knob operating block.
Described child lock for automobile, wherein, the moving lock stop block side on described operating block top is provided with a through hole, and the right angle reverse arm of torsion spring passes this through hole and cage knob links together.
Child lock for automobile of the present utility model has increased safety spring on child lock, safety spring plays the driving effect to the rotation of child lock.During use, when the rotary manipulation piece came locking or release child lock, safety spring can to the operating block application of force time, drive operating block and directly arrive locking or unlocked position, can be accompanied by simultaneously the clear and melodious sound that torsion spring rotates, thus locking or the release of prompting child lock.Locking or release are complete, and be simple in structure, safe and reliable, suitable applying.
