Description

The invention relates to electrical engineering, namely to systems for authorization and identification, automation and remote access control, remote control, remote warning and notification. It can be used as a wearable electronic key for access control systems, an identification card, an electronic alarm key fob, a control panel for household appliances, a key fob with an alarm button.

Remote control devices, such as key fobs for alarms, gate controls and radio frequency identification cards, have become widely used due to the possibility of automating the process of identifying and authorizing the owner of the control device, automating the access process, receiving and exchanging information, and receiving financial services. It has now become the norm to carry electronic key fobs and cards along with the usual keys for mechanical locks. But all these necessary modern electronic keys are no less overall and weighty and do not relieve us of the need to walk around with their voluminous set as with a traditional bunch of keys.

The technical task of the claimed invention is to reduce the size of a wearable remote control device for convenient use, to reduce the cost.

A device for a remote key fob of car alarms is known, including a radio frequency antenna for transmitting radio frequency signals to the security system of a car with commands to arm or disarm, an electronic printed circuit board with electronic components necessary for operation, mechanical buttons to ensure that the key fob perceives user commands, possibly a liquid crystal indicator and necessarily including case, usually plastic, to ensure the integrity of the device, tightness and give an attractive presentation. As an example of such devices, we can cite the well-known electronic key fob device described in one of the paragraphs of the US patent application Hardened electronic key fob number US 2010/0220451 A1 (IPK H05K 5/00) dated September 2, 2010, including an electronic printed circuit board with a plurality of electronic circuits, a keyboard having a plurality of associated buttons for closing said plurality of circuits, an upper housing part, a lower housing part, and a reinforcing piece located at least partially between said electronic circuit board and the keyboard, so that said reinforcing piece and the lower part housings support said printed circuit board. The disadvantage of this type of known devices is that the body of the device occupies a fairly significant volume of the useful part of the device necessary for operation. The design of the electronic board and the location of the components on it, the installation of a galvanic battery, the user interface - everything is done taking into account the location inside the additional component of the device, the case. At the same time, the cost of the finished product is affected by the costs of design, production of the case and assembly of the entire product into the case.

An identification card device is known, including an RF antenna wound around the perimeter or formed by etching copper foil on a flexible printed circuit board, an RF identification chip, possibly a thin battery, a housing consisting of two plastic plates heat-pressed together so that all electronic content is pre-placed between plates. The disadvantage of the known device is the body, which increases the dimensions around the perimeter of the brazed seam and labor costs for the manufacture of the body and Assembly.

The stated technical problem of reducing the size of a portable remote control device and reducing the cost is proposed to be achieved by using the claimed remote control device, which includes at least one remote transmitter of a disturbance of a physical parameter propagating through the medium, at least one electronic printed circuit board, single-layer or multilayer, with built-in or mounted on said electronic board by at least one electronic semiconductor or passive component, and characterized in that said electronic board constitutes at least part of the outer side of the housing.

The essence of the claimed invention is illustrated in the figure of one of the possible implementations. On the figure of the remote control devices are conventionally marked: part of the remote transmitter, which in this case includes a radio frequency antenna 100, an electronic printed circuit board 200, which is simultaneously the bottom side of the housing, with an electronic semiconductor component 201 installed, such as a microcontroller. In the figure, the antenna 100 is shown formed from copper foil by etching or milling on the printed circuit board 100. In addition, the printed circuit board 200 may have other components mounted or embedded, such as a mechanical tactile button 203 for allowing the user to control the device, an LED 202 for displaying information about the result command execution. The advantage of such a device is that the use of an electronic printed circuit board for at least two purposes - a carrier element for fastening electronic components with electrical connection between them and the product case, helps to reduce the cost of the finished product, contributes to manufacturability. Electronic printed circuit boards are made from single-layer or multi-layer foil tec

- 1 039265 stolite, and textolite is a very strong wear-resistant material used in mechanical engineering as a structural material, and is used for the manufacture of various parts: plain bearings, gears and others. Thus, the fulfillment of the technical task is achieved - reducing the cost of the product and increasing the manufacturability by combining the elements of the electronic printed circuit board device and the housing in one. In addition, due to the elimination of a separate housing, the dimensions of the product are reduced.

The figure also shows that the device may include a galvanic battery 204, in this case placed on the printed circuit board 200.

As the upper part of the side 300 of the body, textolite or plastic with the necessary cutouts can be used, for example, a cutout 302 for the LED 202 and a cutout 301 for the tactile switch 203 so that the user can switch the buttons by pressing. In the figure, the other part of the top side 400 is used as a cover to access and change the galvanic battery 204 if necessary, which is conveniently attached with a screw 600 to the rest of the housing. Moreover, parts 300 and 400 can be a textolite, as well as a single-layer or multilayer foil textolite with copper conductors formed in layers for connecting the electronic components of the device, including electronic components possibly mounted on the body elements 300 and 400 from the inside or outside or built into 300 and 400.

The intermediate element of the housing 500 is designed to interface and connect the upper 200 and lower sides 300 and 400 of the housing, strengthening the housing. The element 500 can be provided with cutouts for the components of the device, for example, the figure shows a cutout 501 for a galvanic cell 204. Moreover, the housing element 500 can be made of plastic, wood or textolite material. It can be a single-layer or multi-layer foil textolite with copper conductors formed in layers for connecting the electronic components of the device, including those possibly mounted in the housing element 500. The element 500 may be integral with the bottom side of the housing 200 or the upper side of the housing 300.

If the elements 300, 400 and 500 are electronic printed circuit boards, then this can increase the density of the installation and significantly reduce the dimensions of the product. The manufacture of all body elements from the same textolite material, at least foil, contributes to the fact that the product can be manufactured in a single technological process, reducing the cost.

Housing elements 300, 400 and 500 can be mechanically fastened to each other using glue, epoxy or lamination, including under pressure, including accompanied by thermal heating. Housing elements may have means, such as 303 and 502 for mechanical connection. The means 303, 502 and the like on the housing elements may be threaded connection holes, including for use with threaded screws. The housing elements 300, 400 and 500 may be soldered together at the locations where the respective copper conductors pass over each other. For example, the connection means 303, 502, and the like may be copper solder pads with opposing pads of another housing element. Then 303 and 502 can be used as transitional electrical connections between the electronic circuits of the housing elements 300 and 500. The housing elements 300, 400 and 500 can be mechanically connected using rivets, then the connecting means 302, 502 and the like are holes for inserting a rivet rod. If the body elements, for example 300, 500 and 200, are fastened together by soldering or laminating, then the body can be manufactured in a single technological cycle for the production of an electronic printed circuit board with built-in components.

In the figure, the remote control device shown includes an RF antenna 100 for transmitting an outgoing control message in an outgoing RF signal, so the device can be a car alarm, garage door, remote control, or remote alarm device, including a location device and broadcast its location. The claimed device is not limited to command transmitters, the claimed device can be a transceiver that implements feedback. In the claimed remote control device, the antenna 100 may be part of an RFID card that the remote transmitter uses to transmit an outgoing control message in the reflected or outgoing RF signal. Moreover, the identification card can be passive or active, that is, use the energy of an autonomous power source.

In the inventive remote control device, the remote transmitter may use an infrared optical emitter to at least transmit an outgoing control message in outgoing infrared radiation.

The claimed remote control device, instead of a galvanic cell, may include one or more electric charge batteries.

The claimed remote control device may include other, in addition to LEDs, means of displaying visual information, for example, an LED or liquid crystal indicator, an indicator based on electronic ink.
