Description

Technical field

This utility model relates to the field of protecting vehicles from unauthorized entry / use.

State of the art

In the prior art it is known to provide access to a car using burglar alarms. In general terms, such a system provides for the installation of an immobilizer in a car that can exchange via radio channel with a keyfob transponder with controls (for example, RU 58474 U1, 11/27/2006).

The disadvantage of such a system is the high probability of losing the keychain due to its loss or intentional theft, since usually these keychains are placed on a common keychain with the car key and when moving outside the car are either in the pockets of clothes or in the compartments of bags, briefcases, etc.

In addition, due to the exchange of signals from the transponder and the immobilizer at a sufficiently large distance, it is possible to intercept service information with the subsequent hacking of the car's security system (the so-called code grabbing).

A further development of the state of the art in terms of providing authorized access to a car is the use of so-called keyless access.

As the closest analogue of the proposed utility model, a smart key is selected that includes a housing with an antenna and identification means in it, for example, a transponder (see, for example, M9704698-0004, 10.10.1997, https: //register.dpma .de / DPMAregister / gsm / register? GSNR = M9704698-0004).

The specified analogue has the same significant drawback as the previously known keychains for alarms - it is made in a separate case, which provides for its placement either on a bunch of keys (an opening on the case is provided for this), or by the well-known method mentioned above.

The proposed utility model is designed to overcome these disadvantages of the prior art.

Utility Model Disclosure

The claimed utility model is aimed at solving such a problem as reducing the likelihood of device loss, while achieving such a technical result as improving the security of the access system.

The claimed technical result is achieved by an electronic access device for the vehicle security system, configured to place identification means in it, the housing being made in the form of a ring with the possibility of reaching and securing on a person’s finger.

The case is made in the form of a whole ring or an open ring.

The identification tool is passive or active.

The housing further comprises control means made of plastic and / or glass and / or stone.

The identification tool is rigidly connected to the housing.

The following description is intended to disclose the principle of operation of the proposed utility model and contains information confirming the possibility of its implementation.

The identification tool is a radio frequency (RFTD) tag.

Utility Model Implementation

The proposed utility model allows keyless access to the vehicle interior and works as follows.

Car equipment known from the prior art, which is not the subject of this utility model and is shown for illustration, includes an electronic control unit and touch sensors, usually located in door handles.

When the car owner touches the door handle to open the door, the touch sensor detects the touch and transmits a signal to the electronic control unit.

In response to the received signal, the electronic control unit performs the search operation of the access device located on the person’s finger by sending a search signal through the antenna located in the car.

An access device through an identification means (in the context of this application, an identification means refers to a means that interacts with an electromagnetic field to obtain a system response) located in it, receives a search signal with its antenna and generates a response signal containing identification information in response to this signal .

After receiving a response signal from the access device, the electronic control unit compares the obtained identification information with information contained in the memory for identifying the owner. In case of successful identification, the electronic control unit determines the location of the access device. Having determined that the access device and, accordingly, the car owner are outside the passenger compartment, the electronic control unit sends a command to remove the car from the alarm system and open the central lock.

Having taken the driver's seat, the owner presses the “Start Engine” button, usually provided in cars with keyless entry. The electronic control unit again determines the location of the access device and, if it is detected in the passenger compartment, starts the engine.

After the movement is completed and the owner leaves the car, the electronic control unit locks the doors and sets the car to an alarm. This step can be carried out by touching the owner of the touch sensor on the handle, or by determining by the electronic control unit that the access device has moved outside the vehicle interior.

The housing of the access device in accordance with the proposed utility model is made in the form of a ring that allows you to place it on a person’s finger. In this case, the housing is configured to accommodate identification means connected to the antenna. Such a possibility can be realized, for example, by the presence of a cavity in the thickened part of the body. With this implementation, the ring takes, for example, the form of a ring.

In this cavity is the means of identification. By means of identification is meant passive or active means (for example, transponders) known in the art. As a passive tool that does not require an additional power source, an RFTD tag can be used, consisting of an integrated circuit designed to store, process information, modulate and demodulate the signal, and a transmit-receive antenna. In this case, an additional power source for the operation of the RFTD tag is usually not required, since its operation is ensured by the current induced by the electromagnetic field in the antenna circuit, which can be a signal transmitted from the vehicle’s antenna. The compact dimensions of the known RFTD tags without much effort allow them to be placed in the housing of the proposed access device.

As an active means of identification, known solutions based on a microprocessor, a memory with identification information recorded in it, a compact transceiver antenna and a power source can be applied. Since the proposed solution does not require the transmission of a signal over long distances, such a solution can also be made compact enough to be placed in the housing of the proposed device.

In addition, the housing of the device can be arranged to accommodate controls (buttons) of the vehicle systems, for example, to control the security system. Such a control can be placed in the thickened part of the housing above the cavity in which the identification means is located and can be made of plastic, glass or stone, including precious. Moreover, a rigid fastening of the identification means in the housing will reduce the likelihood of damage to components during shaking that occurs while walking. The fastening can be carried out by means of adhesive bonding, mechanical or embedded in the housing.

The implementation of the housing of the proposed device in the form of a closed ring placed on a person’s finger allows you to refuse to carry separately keychains and place the device in pockets of clothes, in the departments of bags, briefcases, etc. The proposed device during the day can always be in front of the owner, which allows for constant monitoring of its safety. In this case, the unlawful possession of the owner’s luggage will not lead to the loss of the proposed device.

In addition, the execution of the device case in the form of a ring will reduce the power of the signal transmitted from the car, because at the time of reading the identification information, the owner’s hand with the access device placed on it will be on the door handle of the car. This circumstance will enhance the security of data storage from the device, because will not allow attackers to intercept the information transmitted between the car and the access device.
