Description

Mechanical keyboard structure improvement

The present invention is to provide a mechanical keyboard structure improvement, in particular to a mechanical keyboard structure improvement that can increase the angle at which the user observes the display module while increasing the service life.

The keyboard is one of the external parts of the computer. The main purpose is to enter data into the computer. With the current technology, the keyboard can be said to be an indispensable and irreplaceable part of the computer product. In addition to the key-type keyboards, there are many types of keyboards, such as infrared keyboards or contact-type keyboards, but compared to various special keyboards, whether it is cost-effective or easy to use, they are not as good as the key-types that are currently used by everyone. keyboard.

There are currently two types of key-type keyboards, one is a membrane keyboard, and the other is a mechanical keyboard. The membrane keyboard is a resilient membrane placed in the keyboard, which is rebounded by the elastic force of the membrane Keys, and the mechanical keyboard means that each key has its own independent mechanical contact switch, so as to achieve a better pressing feel, while the mechanical keyboard usually displays the content of each key is fixed Therefore, some people will change the key cap to transparent, and set the display screen in the key cap to remind or change the function of the key display.

For example, the new patent certificate number of the Republic of China M400080 "Structure improvement of push switch", which mentioned the technical content of placing an LED screen between the keycap and the circuit board, but this technology fixes the LED screen to the circuit On the board, the LED screen does not move with the keycap, so when the keycap is not pressed, the angle that can be observed is limited, which affects the user's convenience and the service life is shorter, resulting in increased use In addition, this type of mechanical button needs to be designed with a different modular structure to achieve its effect, and cannot be directly installed on the existing mechanical button (Switch), so whether it is in the design , Manufacturing, and installation are more complicated and cumbersome.

In addition, some manufacturers have improved the technology again, connecting the LED screen to the keycap to move up and down with the keycap, but this method also requires additional modular manufacturing and cannot be installed on the mechanical key (Switch) , The feel of pressing will also be different.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the one where the applicant of the present invention and related manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned deficiencies, the inventor of the present invention collected relevant data, evaluated and considered through multiple parties, and based on years of experience accumulated in this industry, through continuous trial and modification, designed this increase to observe the display The inventor of the invention improves the convenience of use of the module, and the installation and manufacturing are more convenient, and the mechanical keyboard structure is improved to extend the service life.

The main purpose of the present invention is to install the display module on the keycap, so that as the keycap undulates up and down, the user can observe that the angle of the display module is more complete, and it can also be directly installed in a general mechanical key , It is more convenient in manufacturing, and the signal transmission interface will be installed under the circuit board through each part, making it not easy to break, thereby increasing the service life.

To achieve the above object, the main structure of the present invention includes: a fixed board, a plurality of perforations provided on the fixed board, a circuit board provided on one side of the fixed board, a plurality of mechanical keys located on the perforations, and a plurality of provided on the machine A display component in a type key, wherein each mechanical key includes a mechanical shaft body, a key cap, and at least one light-transmitting portion, the mechanical shaft body is located at the through hole and connected to the circuit board, and the key cap is connected to the machine via the display component On the shaft body, the light-transmitting part is defined on the keycap. The display assembly includes a display module, a window cover, and a switch fixing plate. The window cover is set in the keycap, and the display module is limited to the window cover. It is located at one side of the light-transmitting part, the switch fixing plate is set on the display module and connected to the mechanical shaft, and the display component also has a signal transmission interface, and one end of the signal transmission interface is connected to the display component , The other end will pass through the fixed board and the circuit board, and be connected to the side of the circuit board facing away from the fixed board.

With the above structure, the user can press the keycap to link the mechanical shaft to transmit the signal to the circuit board, and the display module will cooperate with each other through the window cover and the switch fixing plate to be fixed in the keycap, and Since the keycap is connected to the mechanical shaft body using the switch fixing plate, the display module will move up and down with the keycap at the same time, so regardless of whether the keycap is pressed, the display module will be located next to the light-transmitting portion, so whether the user Press the keycap to fully observe the patterns displayed by the display module, which will make it more convenient for the user to observe the patterns generated by the display module, and the display module will display various patterns through the information provided by the circuit board , The signal transmission interface will bypass the fixed board and the circuit board is connected to the lower side of the circuit board, so when the keycap is pressed to drive the display component to move, the signal transmission interface will be bent, and because the signal transmission interface will wrap around the circuit board At the lower part, the angle of bending can be evenly distributed on the signal transmission interface during bending, so it is not easy to cause damage, so it can increase the overall service life and the display component is directly installed on the general machinery There is no need to design different mechanical buttons for the display module modularization in the button, so it is more convenient to install or manufacture.

With the above-mentioned technology, the angles that can be observed by the display screen in the conventional mechanical buttons are not complete, and the service life is short, and the problems that require additional design are broken through to achieve the practical progress of the above advantages.
