Description

Improved mechanical keyboard structure

The invention provides an improved mechanical keyboard structure, especially an improved mechanical keyboard structure that can increase the angle at which a user observes a display module and increase the service life.

The keyboard is one of the external parts that cooperates with the computer. The main purpose is to input data into the computer. With the current technology, the keyboard can be said to be an indispensable and irreplaceable part of a computer product. In addition to the key-type keyboards, many types of keyboards have appeared, such as infrared keyboards or contact 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 commonly used by everyone. keyboard.

There are two types of keypad keyboards at present, one is a membrane keyboard, and the other is a mechanical keyboard. The membrane keyboard is a film with resilience in the keyboard, which is rebounded by the elasticity of the film. Keys, and the mechanical keyboard is that each key has its own independent mechanical contact switch (switch) to achieve better pressing feel, while the mechanical keyboard, usually the content displayed by each key is fixed Therefore, some people will change the keycap to be transparent and set the display screen inside the keycap to remind or change the function of the key display.

For example, the Republic of China's new patent certificate number M400080 "Structure improvement of push-button switches", which mentions the technical content of placing an LED screen between the keycap and the circuit board, but this technology is to fix 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 convenience of the user, and the service life is short, leading to increased use In addition, such mechanical keys need to be designed with different modular structures before they can achieve their effects. They cannot be directly installed on the existing mechanical keys (Switch), so whether it is in the design , Manufacturing, and installation will be more complicated and troublesome.

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 another modular production and cannot be installed on the mechanical button (Switch) There will be differences in the feeling of pressing.

Therefore, how to solve the above-mentioned conventional problems and shortcomings is where the applicants of the present invention and relevant manufacturers engaged in this industry are eager to study and improve.

Therefore, the inventor of the present invention, in view of the above-mentioned shortcomings, collected relevant information, evaluated and considered from various parties, and based on years of experience accumulated in this industry, and continued to make trials and modifications, he began to design such an increase. Observable display The angle of the module improves the convenience of use, while the installation and manufacturing are more convenient, and the mechanical keyboard structure of the inventor is improved to make the service life longer.

The main purpose of the present invention is to set the display module on the keycap so that the user can observe the angle of the display module more completely as the keycap rises and falls, and can also be directly installed in general mechanical keys. , It is more convenient to manufacture, and the signal transmission interface will be installed under the circuit board through each part, so that it is not easy to be broken, thereby increasing the service life.

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

With the above structure, the user can press the keycap to link the mechanical shaft body 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 a switch fixing plate, the display module will move up and down at the same time with the keycap. Therefore, regardless of whether the keycap is pressed, the display module will be located next to the light-transmitting part, so the user regardless of whether By pressing the keycap, you can fully observe the pattern displayed by the display module, which allows users to observe the patterns generated by the display module more conveniently, and the display module displays various patterns through the information provided by the circuit board. The signal transmission interface will bypass the fixed board and the circuit board and be connected to the lower side of the circuit board. Therefore, when the keycap is pressed to move the display module, the signal transmission interface will be bent, and due to the signal transmission The interface will go to the bottom of the circuit board, which can evenly distribute the bending angle on the signal transmission interface during bending, so it is not easy to cause damage, so it can increase the life of the overall use, and the display component is directly It is installed in general mechanical keys, and it is not necessary to design different mechanical keys for the modularization of the display component, so it is more convenient to install or manufacture.

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