Abstract
An improved burglarproof locking device for a vehicle is disclosed. The locked status of the locking device is not released by a strong impact or by an external magnetic force, thereby preventing the car from being stolen. Thus the reliability of the locking device is improved.
Claims13
A burglarproof locking device for a vehicle, comprising:
- a locking part housing forming a locking slot therein;
- an actuator with a locking protuberance formed thereon configured for mating into said locking slot;
- an electromagnet configured to move said actuator in a negative axial direction;
- a spring configured to move said actuator in a positive axial direction;
- a locking block axially slidably installed within said locking part housing configured to interlock said locking part housing with said actuator to inhibit rotation between said locking part housing and said actuator upon axial movement of said locking block;
- and
- an elastic member for elastically supporting said locking block to remotely separate it from said actuator.
4 more elements
A locking device for a vehicle, comprising:
- a locking block slidably biased in an axial direction by a first spring;
- an actuator configured for axial movement, slidably biased along the axial direction by a second spring and defining a slot for receiving said locking block;
- a housing defining a channel for slidably receiving said locking block wherein said locking block is inhibited from rotation within said housing and wherein said housing is configured to rotatably lockably receive said actuator;
- an electromagnet configured to axially slidably attract said actuator against said second spring;
- and
- wherein a force of the first spring applied to the locking block is greater than the force applied to the locking block by the electromagnet.
3 more elements
A locking device for a vehicle, comprising:
- a locking part housing formed around a longitudinal axis with an open end facing a negative axial direction;
- a locking slot defined in the open end of the locking part housing;
- an actuator biased in a positive axial direction with a locking protuberance configured for mating into said locking slot;
- an electromagnet configured to move said actuator in a negative axial direction;
- a locking block axially slidably installed within said locking part housing configured to interlock said locking part housing with said actuator to inhibit rotation therebetween upon said locking block being moved in the axial direction;
- and
- an elastic member for elastically supporting said locking block to remotely separate it from said actuator.
