Abstract

The utility model relates to an infrared remote-control television set steering device, the integral structure of which is a disc body. The utility model is characterized in that the upper part of the disc body is provided with a rotary disc, and the lower part of the disc body is provided with base; the rotary disc is connected with a mechanical rotary device which is arranged on the base; an upper cover is fixed on the upper part of the rotary disc; an Infrared receiver IR is arranged on the side wall of base; the Infrared receiver IR is orderly and electrically connected with four operational amplifiers IC1 and a double-D trigger IC2; the output terminal IC1 is electrically connected with a motor driver IC3, and the output terminal of the IC3 is electrically connected with a driving motor. The utility model can make the personal remote controller achieve the purpose of remote-control rotation with sensitive rotation. The utility model has the advantages of convenient operation, stable transmission torque, few mechanical part, and lower cost for manufacture.

Description

The steering gear of infrared remote control television set

The utility model relates to a kind of used as television whirligig, the steering gear of particularly a kind of infrared remote control television set.

Television set is in indoor putting position relative fixed, people just can not be over against video screen when watching television set, long-time like this watching can produce sense of fatigue, eyesight is suffered damage, and particularly to influence meeting bigger to teen-age, can bring adverse consequencess such as stravismus, if rotate television set with hand getting, can make troubles to people on the one hand, especially, can damage furniture surface on the other hand for just more difficult rotation of large screen set.

The purpose of this utility model provides a kind of remote controller with television set self and just can reach remote control rotation purpose, rotate sensitivity, infrared remote control television set steering gear easy to use.

The purpose of this utility model realizes by following structure: the utility model is the steering gear of a kind of infrared remote control television set, its overall structure is a disc, the top of disc is a rotating disk, the bottom is a base, rotating disk is connected with a mechanical rotary device that is installed on the base, loam cake is being fixed on rotating disk top, and infrared receiver IR is installed on base side wall, infrared receiver IR and four-operational amplifier IC ₁, double D trigger IC ₂Order is electrically connected, IC ₁Output and motor driver IC ₃Be electrically connected IC ₃Output be electrically connected with CD-ROM drive motor M.

The utility model can be placed on television set in use and cover, the utility model has power line, can directly use the 220V AC power, the remote controller of any television set all can be used as controller of the present utility model and uses, use very convenient, after pressing any button on the remote controller, the infrared signal that remote controller sends is received by IR and converts the corresponding signal of telecommunication to, through IC ₁Deliver to IC after amplifying shaping ₂, IC ₂Form flip and flop generator, produce a control signal and be transmitted back to IC again ₁, IC ₁Will produce a control voltage makes to anticlockwise luminous indicating lamp connection, IC simultaneously ₁Can delay time 5 seconds, this is that rotating disk produces misoperation when adjusting television set in order to prevent to use a teleswitch, and control signal can be delivered to IC then ₃, by IC ₃Produce drive signal and make CD-ROM drive motor M work, rotating disk will be rotated counterclockwise.After unclamping the button of remote controller, press the button of remote controller once more, by IC ₂The control signal that produces is through IC ₁After the amplification, the up time indicator light is connected, simultaneously through IC ₃CD-ROM drive motor M work clockwise rotates rotating disk.Also according to a mechanical rotary device is arranged, this device rotation sensitivity is good for the utility model, and the transmission torque is stable, and mechanical part is less, so manufacturing cost is lower, but wide popularization and application.
