Problems solved by technology

However, the traditional keyboard has a general disadvantage, that is, in winter, it will be unbearably cold, and even input errors, etc., especially when the temperature is too low, it is easy to freeze hands. If you use the keyboard for a long time, especially It is easy to grow chilblains, which is not good for the human body

Embodiment Construction

[0011] The present invention is now described in detail in conjunction with the accompanying drawings. A heating keyboard membrane includes an electric heating membrane, a heat-resistant soft glue 2 , a controller 3 and a USB connector 4 . The electrothermal film includes a current-carrying bar 11 and an insulating film 12 .

[0012] The electrothermal film is placed in the heat-resistant soft film 2 . The dimensions of the electrothermal film are consistent with those of the keyboard. The structure inside the electrothermal film includes a current carrying bar 11 and an insulating film 12, and the current carrying bar 11 is arranged according to the gap of the keycap of the keyboard. The current-carrying bar 11 is a heating resistor. The insulating film 12 is wrapped outside the current-carrying bar 11, and the insulating film 12 is made of an insulating polyester film; it is made into an electrothermal film matching the gap between the keycaps on the keyboard. The heat-re...

Abstract

The invention provides a heating keyboard membrane, and belongs to the field of electronic devices. The membrane includes an electric heating membrane, a heat resistant soft rubber, a controller and aUSB connector. The electric heating membrane includes current carrying strips and an insulating membrane. The electric heating membrane is placed in a heat resistant soft membrane. The current carrying strips are arranged according to slits of keyboard key caps. The insulating membrane is wrapped around the current carrying strips to form the electric heating membrane which matches the silts among the keyboard key caps. In addition to the electric heating membrane, the heat resistant soft rubber is further wrapped. The controller is connected to the current carrying strips in the electric heating membrane, and the controller is composed of a processor and a temperature control circuit. The controller is connected to the USB connector. The heat resistant soft membrane is transparent. The heating keyboard membrane has a simple principle, can set regulation by itself, and provides a temperature in winter during office businesses for people to withstand cold and prevent hands from frostbite.

Description

technical field [0001] A heating keyboard membrane belongs to the field of electronic equipment, and in particular relates to a keyboard membrane. Background technique [0002] Along with the progress of life, computer has come into mass family, and keyboard is as the accessory of computer, and its importance degree, can be described as the right arm of computer, it is the main input means of computer, is the bridge that people and computer communicate. But the traditional keyboard has a general disadvantage, that is, in winter, it will be unbearably cold, and even input errors, etc., especially when the temperature is too low, it is easy to freeze hands. If you use the keyboard for a long time, especially It is easy to develop frostbite, which is not good for the human body. Contents of the invention [0003] The solution of the present invention is to invent a heating keyboard membrane to address the shortcomings of the above solutions. [0004] A heating keyboard film...
