Description

Keyboard lift drive

technical field

The utility model relates to a driving device, in particular to a driving device for lifting and lowering a keyboard of a notebook computer.

Background technique

Notebook computers are widely used because they are easy to carry, easy to operate, and not limited by time, place or region. In order to prevent other people from touching the keyboard and affecting the operation of the notebook computer, or causing the data of the notebook computer to be destroyed, etc., a safe anti-touch device will be installed on the keyboard of the notebook computer. The frame of the keyboard of the notebook computer can For the lifting displacement, use the frame to rise and move to the top periphery of multiple keycaps, so that each keycap will not be pressed down by accidental touch. When the user wants to use the notebook computer again, the frame of the keyboard Lower and reset to the bottom periphery of multiple keycaps, so that each keycap can be manipulated and pressed to input electronic signals. However, the height of the frame must be higher than the thickness of each keycap, so that each keycap can fully enter the frame. In the hole, the frame must rise about 2.0mm away from the base and then be located around the top of each keycap, but it cannot effectively reduce the overall height of the keyboard, but slightly increases the height of the keyboard, which is not suitable for light and thin electronic products. , short and small design requirements, and the frame is driven by the lifting mechanism to rise to the position around each keycap. Since the lifting mechanism only drives one position at the bottom of the frame, the entire frame must be lifted upwards, and the other positions of the rectangular frame It cannot be driven by the lifting mechanism, and it is easy to increase the difficulty of operating the lifting mechanism, and there are still many deficiencies in practical applications.

In addition to the keyboard application of notebook computers, wireless communication devices have developed rapidly in recent years, and various smart phones and tablet computers have been widely used. Such as touch screens, which allow users to directly press the touch screen instead of keyboard operations, thereby reducing the size of smart phones, tablet computers, etc., which is more in line with the design concept of light, thin, short, and small electronic products. The size of the touch screen of a smart phone or a tablet computer is small (about 5 inches, 7 inches or 10 inches, etc.), although it is more convenient to carry, but when the user presses the touch screen with a finger, The area of the finger pulp is larger than the size of the keyboard symbols displayed on the touch screen, and it often happens that the fingers touch the surrounding key symbols by mistake, resulting in wrong input information, and the input must be re-operated, which affects the operation and is quite time-consuming. , It takes a lot of work, and in order to improve the lack of operations such as smart phones and tablet computers that are not easy to be touched and manipulated, and input electronic signals, they have developed keyboard docks with multiple keycaps, using keyboard docks for smart phones or After the tablet computer is electrically plugged in, electronic signals can be input through the multiple keycaps on the keyboard base, and it is convenient to control smart phones or tablet computers, etc. When the keyboard base is not in use, the keyboard base can be placed It is reversed to serve as a support frame for supporting electronic devices, but this kind of keyboard stand that can be assembled with electronic devices also has the same problem as the height of the notebook computer frame cannot be lowered when it is raised and lowered, and it is easy to cause the keyboard stand to be lifted by the lifting mechanism. , the strength of the lifting mechanism's top support frame is not enough and it automatically drops, and there are some inconveniences and troubles in use. The related problems, troubles and lacks of such control keyboards moving up and down on the base, but not reducing the overall height, are Relevant manufacturers engaged in this industry are eager to study the direction of improvement.
