RU2496958C2 - Locking of vehicle door lock - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: to eliminate the possibility of shutting and blocking of vehicle locks with a key forgotten in an ignition lock, an additional interlock is proposed, which prevents lowering of a door blocking button, if the key is in the ignition lock. For this purpose the circuit of the actuation device of the door lock contains an additional contact of the ignition lock. A special buzzer will prompt about a mistake made.

EFFECT: specified interlock acts as an interlock that prevents lowering of a blocking button of an open vehicle door to prevent its accidental locking.

Description

The present invention relates to the side doors of a passenger car, in particular to the design of locking devices, and can be used in their manufacture.

The car is designed to carry passengers and baggage, most often it is equipped with four passenger doors that provide entry and exit from the vehicle and are securely pressed to the body with locks to prevent unauthorized persons from accessing.

On a car equipped with a central lock with electric locks, all doors can be locked or unlocked simultaneously both from the outside - with a key through the driver’s door lock, and from the inside - with the lock button on the same door, as well as remotely using the remote control. The lock button for other doors only locks this door. The locking device includes a push button located in the guide sleeve, and a rod connected at one end to the button and the other end acting on the locking mechanism for locking the door lock. The guide sleeve is mounted on the upper inner surface of the vehicle door, with the outer parts of the sleeve and buttons located outside, and the thrust, locking locking mechanism and door lock are located in the door cavity.

To lock the door lock, press the push button through the guide sleeve into the door cavity. Together with the push button, the rod moves, acting on the locking mechanism and translating it into the locked position of the door lock. The locking of the vehicle door lock can also be carried out by an electric actuator acting on the locking control lever. The lock is unlocked mechanically by applying the handle of the lock drive through the lock rod to the lock control lever, or electrically by applying the electric drive to the lock control lever, which, turning in the opposite direction, unlocks the lock. The electrical and mechanical work of each function of the lock are independent and do not interfere with each other at all phases of the lock. The lock can operate from an electric drive independently of mechanical controls, and in the event of a failure of the electrical equipment, the lock can work mechanically.

Examples of the car door lock structure are presented in patents DE 10109827 (A1) of 09/19/2002, E05B 65/12, E05B 13/00, E05B 53/00; WO 03004810 (A2) dated 1/16/2003, E05B 65/12, E05B 65/20, E05B 65/36, E05B 17/22; DE 10240003 (A1) dated 11.03.2004, E05B 65/12, E05B 65/20; JP 2005219665 (A) from 08/18/2005, B60J 5/10, E05B 65/20; US2006157989 (A1) dated 07.20.2006, E05B 65/32, E05C 3/06, E05B 65/20; RU 2413825 C2 dated 03/10/2011, E05B 65/20; CN 102080479 (A) dated 06/01/2011, E05B 15/00, E05B 47/06, E05B 65/20.

The side door locks can be locked from the outside without using a key, for which you need to press the lock button for the open door lock and slam the door. The driver uses this method of locking the car if he needs to pick up something voluminous from the rear seat. He picks up a bag, item or child from the back seat through the open back door, he presses the lock button on the closed driver’s door while his hands are free, and picking up the load, slams the back door, blocking all the locks. But at the same time, he can forget the key in the ignition switch, which causes great inconvenience - you need to bring another key from the house, but you cannot leave the car with the key in the ignition switch, putting it in danger of theft.

The claimed invention to eliminate this drawback proposes an additional lock that does not allow to lower the door lock button if the key is in the ignition. For this, an additional ignition switch contact is introduced into the circuit of the door lock actuator. A special buzzer will tell you about the mistake made. The specified lock acts like a lock that does not allow to lower the lock button of the open driver's door to prevent it from being accidentally locked.

The essence of the claimed invention lies in the fact that the proposed additional locking that does not allow to lower the door lock button if the key is in the ignition. For this, an additional ignition switch contact is introduced into the circuit of the door lock actuator. A special buzzer will tell you about the mistake made.

The technical result of the claimed invention is an additional lock that does not allow to lower the door lock buttons if the key is in the ignition.

The specified technical result is achieved due to the fact that an additional ignition switch contact is introduced into the circuit of the door lock actuator. A special buzzer will tell you about the mistake made.

New significant features of the claimed invention are:

- additional lock, which does not allow to lower the door lock buttons, if the key is in the ignition;

- the introduction of an additional contact of the ignition switch in the actuator circuit of the door lock. A special buzzer will tell you about the mistake made.

This description does not limit the scope of the invention and is intended for sufficient disclosure of information, is an example embodiment of the invention, and although the preferred options for its implementation have been presented above, it should be understood that the present invention is not limited to the options and modifications described here. A person skilled in the art can envision numerous changes and additions to the form and details in accordance with the information disclosed herein, as well as other embodiments of the present invention without departing from the spirit and scope of the invention as defined by its claims. In particular, it should be understood that any of the above structural elements can be used in combination or separately to achieve all or some of the advantages of the invention.

However, there are other options not described here for which the present invention is applicable. Thus, the present description is illustrative rather than restrictive, and the specific details shown and described do not limit the present invention. In the foregoing claims, any distinguishing feature described as a means of performing a function should be construed as encompassing any means known to those skilled in the art by which this function can be performed, and should not be limited only to the demonstrated distinctive features and structures, or their equivalents.
