Abstract

The present invention relates to a pivotable TV that can be controlled by a remote controller. A step motor or the like on joints formed at the back of a TV monitor is used to control the lateral pivoting and vertical angular pivoting of the TV monitor by means of the remote controller. The height of a stand for the monitor is adjusted by using a rack and pinion gear, a hydraulic jack or a pneumatic jack, a screw jack, or the like. An actuator is used to enable the TV monitor to be moved forward or backward. All of the above adjustments are made by respective switches on the remote controller.

Description

Rotatable TV

The present invention relates to a TV that can be rotated by a remote control, the technical field of the present invention relates to a remote control

The principle of the remote control

Remote control or remote control, also known as remote control, is used to operate indirectly using a device without operating a remote machine or device directly with human hands or feet.

A remote control device that can be easily accessed in everyday life is a remote control that is used to turn on and off television, video, audio, etc., and to change channels and adjust the volume. How does this remote control work?

The most essential part of the remote control is called a semiconductor infrared laser. When you press a button on the remote control, the chip on the electronic circuit emits an infrared (wavelength 940 nm) beam. The infrared beam carries a coded signal and varies in sign depending on the button pressed, which consists of a combination of zeros and ones.

When the encoded infrared beam reaches the television receiver, a photodiode, a light-sensitive semiconductor device, converts infrared light into an electrical signal. This signal does the work of changing. This signal performs various operations such as changing channels and adjusting the volume through a damper circuit, a radio wave circuit, and the like. Infrared light is less straightforward than visible light, so you'll have to push a button toward the television when using the remote control.

The remote control is a very convenient device that can be operated remotely without having to touch it when the TV is turned on or off or changes channels. It is an abbreviation of remote control and mainly uses ultrasonic waves. In other words, the ultrasonic signal emitted from the remote control is converted into an electrical signal from a kind of microphone attached to the inside of the television. The signal is analyzed by a remote control device in the television to enable switches, sound controllers, and channel selectors.

And the remote control we currently use to control TVs in our homes is the infrared remote control. Infrared light is invisible, so there is no indication. There is a remote ... there is a small light bulb, which is an infrared light bulb. It is called an infrared LED.

First of all, it is controlled by using these two devices. Here, the remote control blinks when the button is pressed according to a predetermined rule. There is a blinking rule and flashes according to the prescribed rule. When the signal comes to the sensor, the TV analyzes the signal and changes the channel by the electronic chip of the TV. All others likewise designate multiple signals to create buttons and make the TV run according to those signals.

The background technology of the present invention is a remote control.

'Hand of the remote control' electromagnetic waves = The remote control is short for the English language 'remote control' which means 'to remotely control the machine.' In addition to TV, air conditioner and video are all operated by remote control.

The secret to operating electronics with a remote control lies in the electromagnetic waves. Electromagnetic waves are a combination of light, radio waves, infrared rays, ultraviolet rays, and X-rays. Among these, only visible light is visible.

When we press a certain button on the remote control to give a command, the infrared, ultrasonic and radio waves come out of the bulb in front of the remote control. The electronics then accept this electromagnetic wave and execute a command. The remote control used for the TV usually uses infrared rays.

Infrared operation: When sunlight passes through the prism, it is divided into seven rainbow colors in the order of red, orange, yellow, green, blue, blue, and purple. Among them, electromagnetic waves with a lower frequency than red are infrared rays, and electromagnetic waves with a higher frequency than purple are ultraviolet rays.

Making infrared rays inside a machine is a semiconductor called a "light emitting diode," while receiving infrared light is called a "light emitting diode." There is a light emitting diode inside the remote control and a light receiving diode inside electronic products such as TV audio.

Therefore, if you press TV channel 7 with the remote control, infrared rays with a unique frequency already input are emitted from the light emitting diode, and the light receiving diode which is supposed to operate channel 7 on the TV accepts it and changes the screen to channel 7. In addition, when the volume button on the remote control is pressed, the infrared light flashes at a high speed.In this case, the first signal is that the volume button has been pressed, and then the number of times the button has been pressed through the number of times the infrared light blinks is used. There is awareness, sound up or down.

The remote control works even if you aim it in a different direction, not directly at the appliance. This is because infrared light is reflected on walls, mirrors, and furniture. However, it does not work well with black wallpaper. This is because black absorbs infrared light.

Strongest infrared remote control = In addition to the main body, computers, printers, mice, keyboards, speakers, scanners and other peripherals are used. As a result, the wires that connect these devices together are usually cluttered with spider webs.

Servomotor [servomotor]

An operating unit of a servo mechanism that drives a load by a control signal.

Depending on the power source of the servomotor, there are electric (servo motor), pneumatic (air servomotor), hydraulic (hydraulic motor) and so on. In general, a servomotor is often referred to as a servomotor.

Servo motor is a control motor with fast response and wide speed control. It is classified into DC servo motor and AC servo motor according to its power source. Most of AC servomotors are three-phase servomotors.

Since these operations are repeated such as stopping, starting, reversing, and the like, they are considered in design so as to improve the heat dissipation effect or to speed up the change of the operation. The servomotor is operated according to the control signal. To do this, a device that receives the control signal and amplifies it and drives the servomotor is called a servo amplifier.

Stepping motor

[stepping motor]

A motor that rotates a certain angle each time a pulse signal is given.

It is a motor that moves by an angle corresponding to the number of input pulses. It is also called a pulse motor or step motor. The rotation angle of the motor is completely proportional to the number of input pulses, so the rotation angle can be controlled accurately. Because of this feature, it is used in OA machines such as NC machine tools, industrial robots, printers and copiers. It is one of the important electric motors in mechatronic machines. In particular, linear movement is called linear stepping motor.

Step motor

[stepper motor]

Electric motor rotates at a certain angle by a pulse-shaped voltage. The rotation angle is proportional to the number of input pulse signals, and the rotation speed is proportional to the frequency of the input pulse signal. The figure shows the three-phase electric motor of the 1-phase female, and there are other multi-phase motors.

In this case, the means to solve this problem is to adjust the rotation of the left and right and up and down angles to the TV by using the remote control, by using a step motor, etc. in the joint, and to move back and forth using a linear motor. The height of the cradle is adjusted by pinion gear, hydraulic jack, pneumatic jack or screw jack.

Also, by adjusting the height of the TV, it is convenient for the viewer to adjust the horizontal, vertical and height of the TV. have.
