Description

The invention relates to the field of automotive technology, and more precisely to anti-theft systems.

LEVEL OF TECHNOLOGY

The design of means for locking the hood, trunk, doors and transmission of modern cars often provides for the connection of a control element (usually a lever or other mechanical element located in the passenger compartment) with a controlled element of the locking means (hook, latch, bolt, etc.) by means of a flexible thrust (see, for example, RF patents for inventions No. 2274563, 2668150 and 2629484).

However, when designing new means of blocking, containing a flexible rod between the control and controlled elements and an additional control element that makes it possible to block the movement of the flexible rod (which in turn can be controlled by means of a flexible rod or by means of an electronic drive), so as to impede the transmission of control action from the control to the controlled element, a technical problem arises in that the user, having forgotten about blocking the flexible rod, can apply excessive force to the control element, thereby damaging either the control element or the flexible rod. The reason for this is that the tactile sensations experienced by the user when acting on the control element when the flexible connection is locked is almost identical to the sensations that occur during normal operation of the mechanisms (the user can explain the lack of movement of the control element by tight engagement in the rubbing parts).

DISCLOSURE OF THE INVENTION

In this regard, it is an object of the present invention to provide a locking device that provides tactile feedback informing the user that the flex rod is locked, thereby protecting the control element and the flex rod from excessive force from the user and destruction.

The technical result achieved when using the invention is to prevent breakage of the control element and breakage of the flexible rod.

The above problem is solved due to the fact that the proposed device for preventing damage to mechanical systems, including a control element and a controlled element connected to each other by means of flexible rods in the shell and a movement blocking element made with the possibility of preventing said movement, contains:

a body made with the possibility of fixing the shells of the mentioned rods from reciprocating movement,

longitudinally movable element made with the possibility of reciprocating movement relative to the body,

spring element,

characterized by the fact that it contains

said longitudinally movable element is configured to interact with said movement blocking element,

the end of one of said rods is spring-loaded relative to said longitudinally movable element by said spring element.

The aforementioned longitudinally movable element, in one of its particular embodiments, can be a tube installed inside a tubular channel in the aforementioned housing, having holes for cables with obstacles for said tube at the ends, one of the ends of said tube being connected to one of the aforementioned cables, and inside said tube is the above-mentioned spring element in the form of a coiled spring, with one end of said spring fixed to the other end of said tube, and the other end of said spring connected to another of the above-mentioned cables.

The aforementioned locking element, in one of its particular embodiments, may be an element capable of transverse movement relative to the direction of the aforementioned reciprocating movement so as to impede the movement of the aforementioned longitudinally movable element.

The aforementioned locking element, in a particular embodiment, can be provided with a drive, preferably a mechanical drive or an electromechanical drive.

In the following, the aforementioned device, described in general categories, is explained by the example of some particularly preferred embodiments, which provide additional advantages.

The aforementioned flap, in one of the particular forms of embodiment of the device according to the invention, is a door, or a bonnet, or a trunk lid.

It should be understood that in this text, the device is characterized only by such features that are sufficient to solve the problem, implement the purpose and achieve the selected technical result; no special mention of all the features and utilitarian characteristics of the device is required if specialists should know that products of the same kind have such features and utilitarian characteristics and without them the main purpose is not realized; all the more, there is no need to limit the generalized features to any specific options, if such are to be known to specialists and (or) can be selected according to known rules.

CARRYING OUT THE INVENTION

As shown in FIG. 1 and 2, a device for preventing damage to mechanical systems, including a control element (1) and a controlled element (11, 12) connected to each other by means of flexible rods (2) in a shell (3) and a movement blocking element (8) configured preventing the said movement, contains:

a body (4) made with the possibility of fixing the shells of said rods (2) from reciprocating movement,

a longitudinally movable element (6), made with the possibility of reciprocating movement relative to the body (4),

spring element (7),

characterized by the fact that it contains

said longitudinally movable element (6) is configured to interact with said movement blocking element (8),

the end (5) of one of said rods (2) is spring-loaded relative to said longitudinally movable element (6) by means of said spring element (7).

As shown in FIG. 1, in the case when the device is used to prevent damage to the cables of a standard hood lock, the rods (2) are cables in a sheath, the controlled element (11, 12) is the standard hood lock, and the control element (1) is a lever in the passenger compartment.

Before installing the device according to the invention, when opening the standard hood lock, the lever (1) is moved axially to the left, which entails the movement of the cable (2), and the opening of the blocking element (12) of the standard lock. When the lever (1) is released, the spring (13) returns the lever (1) to its original position.

When installing the device according to the invention, the standard cable (2) is broken, connecting the obtained ends by means of the device elements in such a way that the device, by means of the movement blocking element (8), can block the movement of the cable end (3) connected to the controlled element (11, 12).

As shown in FIG. 1. and 2, the control of the blocking element (8) can be carried out using a flexible rod (similar to the mechanism in the RF patent for utility model No. 145849). However, in other embodiments, the blocking element (8) can be controlled differently, for example, by means of an electric drive or a mechanical drive, and, directly, from a motor or solenoid installed inside the housing (4) with fixed positions "open" and "closed".

If the locking element (8) is in the "open" position, then to open the hood, the user moves the lever (1), the cable (2), the longitudinally movable element (6) and then the cable (2), which entails the opening of the lock ( eleven). The spring element (7) installed in the longitudinally movable element (6) has a compression force higher than the spring (13) in the standard lock (11) and the opening occurs in the normal mode.

The selection of the stiffness of the spring element (7) allows the installer to provide such a compression force that will not only protect the lever (1) from physical damage, but also regulate the force of movement of the lever (1) when the rod is locked.

If the device is locked, then when the lever (1) is actuated, tactile feedback is provided: the user will feel the resistance of the spring element (7) to the stroke of the lever (1), while in the absence of the device according to the invention, there is no lever stroke in the locked position.

Thus, the proposed device makes it possible to prevent breakage of the vehicle locking systems equipped with an additional locking element.
