Description
Technical field
The utility model belongs to automobile door lock domain, particularly relates to a kind of concealed automobile door lock.
Background technology
Most its keyhole of automobile mechanical door lock be expose visible, the insertion release of Key like this.But along with popularizing of centrally controrlled locking system technology, people have been accustomed to using centrally controrlled locking system carry out door opening and lock door, and seldom use mechanical door lock, for example at electron key, losing or lost efficacy is just to utilize mechanical key to unblank.The exposed automobile door lock of above-mentioned keyhole, lock core cover cap contains the keyhole that holds keyhole conventionally, and the lock core cover cap with keyhole greatly reduces the aesthetic property of handle entirety, has also improved the difficulty of moulding.And common lock core cover cap exposes keyhole, and anti-theft effect is not fine.
For addressing the above problem, there is on the market a kind of concealed automobile door lock, its lock core cover cap has hidden lock core completely, and keyhole does not expose.
Existing a kind of concealed automobile door lock as shown in Figures 1 to 7, handle assembly is provided with plastic sealing gasket 3a between lock core 1a and lock core cover cap 2a, on plastic sealing gasket 3a, be formed with claw 4a and claw 4b, lock core cover cap 2a is provided with screens 5a and screens 5b, respectively claw 4a and the claw 4b on clamping plastic sealing gasket 3a, realizes spacing in car door inward-outward direction of lock core cover cap 2a with this; Simultaneously on lock core 1a, be provided with protruding 6a, protruding 6a is stuck in the upper recess 7a arranging of lock core cover cap 2a, with this, realizes spacing on car door fore-and-aft direction of lock core cover cap 2a.In addition, in the joint portion of handle 9a and lock core cover cap 2a, be also provided with crimping structure to push down lock core cover cap 2a, prevent that lock core cover cap 2a from getting loose, crimping structure as shown in Figure 7, comprise the crimping muscle position 9b extending to form laterally and be arranged on the raised ribs position 2b on lock core cover cap 2a from described handle 9a, when handle 9a falls, meeting muscle position 9b, to be pressed in raised ribs position 2b upper, with this, strengthens spacing in car door inward-outward direction of lock core cover cap 2a.The soffit of lock core cover cap 2a is provided with lock core cover cap hole 8a, when needs are pulled down lock core cover cap, first pull-up handle 9a, then inserts lock core cover cap hole 8a by mechanical key 10a, take lock core cover cap hole 8a as fulcrum, the direction of arrow rotary machine key 10a in Fig. 1 pries open lock core cover cap 2a again.
But in above-mentioned concealed automobile door lock, clamping part comprises handle 9a, plastic sealing gasket 3a, lock core 1a and lock core cover cap 2a, the part that relates to clamping cooperation is more, complex structure, and each part matching part tolerance is high, and processing cost is high; And screens 5a and screens 5b on the claw 4a on plastic sealing gasket 3a and claw 4b and lock core cover cap 2a are plastic construction, claw 4a and the claw 4b intensity of plastic construction are little, easily cause clamping insecure; And the position of lock core cover cap and handle crimping is narrower, there is free gap at crimping position, and crimping is insecure, causes lock core cover cap 2a in vehicle traveling process easily to come off; And lock core cover cap 2a is used meeting laying dust in position upper and handle 9a crimping for a long time, affects attractive in appearance; In addition, the frequent picking lock core cover cap hole 8a of mechanical key 10a, easily causes the wearing and tearing of picking lock core cover cap hole 8a even to damage.
