SUMMERY OF THE UTILITY MODEL

The notebook computer with the detachable display device can change the height of the display screen.

In order to achieve the above object, the present invention provides a notebook computer with a detachable display device, the display, a keyboard body and a connecting board for connecting the display and the keyboard body; the height of the display is adjusted by the aid of a telescopic mechanism; a connecting part is arranged in the connecting plate in a sliding manner; the telescopic mechanism comprises a motor, a gear, a rack and a rotating shaft; the motor is fixedly arranged on the side wall of the connecting piece; one end of the rotating shaft is rotatably connected with the inner wall of the connecting plate, and the other end of the rotating shaft is fixedly connected with an output shaft of the motor; the gear is coaxially fixed with the rotating shaft and is rotationally connected with the rotating shaft; a through hole is formed in the connecting plate below the connecting part; the rack is arranged in the through hole in a sliding manner; the rack is fixedly connected with the inner wall of the connecting plate through a first spring, and the other end of the rack is contacted with the connecting part; the gear is meshed with the rack.

The principle of the scheme is as follows: inserting the display into the connecting part, connecting the display and the keyboard part body together, starting the motor, and when the position of the display needs to be adjusted to be high, enabling the motor to rotate forwards, so that the gear rotates forwards, the gear enables the rack to move upwards, the first spring is stretched, and when the display is in a proper position, closing the motor to stop the gear to rotate, so that the rack stops moving; when the position of the display needs to be lowered, the motor is rotated reversely, the gear is rotated reversely by the motor, the rack moves downwards by the gear, the first spring is compressed, and when the display is in a proper position, the motor is turned off to stop the gear from rotating, so that the rack stops moving.

The scheme has the beneficial effects that: this scheme can adjust the display height, makes the operator can adjust comfortable height, reduces operator's health damage, when adjusting the display height through the spring, makes the display remove gently, makes the display stable. Thereby adjust the high operator's health damage of display height reduction through setting up motor, gear and rack structure adjustment connecting plate, compare treatment cost behind the operator's health damage, motor, gear and tooth structure cost are lower. If the height of the display is increased by using the heightening pad and the like, the height of the keyboard body is also changed, and the operator can use the keyboard body inconveniently.

Furthermore, a brake switch used for limiting the rotation of the gear is arranged in the connecting plate; the brake switch comprises a ratchet wheel, a pawl and a rotating block for controlling the distance between the ratchet wheel and the pawl; the ratchet wheel is coaxially connected with the rotating shaft; the pawl is arranged on the inner wall of the connecting block in a hinged mode; the ratchet wheel is matched with the pawl; one end of the rotating block is positioned in the connecting plate, and the other end of the rotating plate is positioned on the surface of the connecting plate. When the position of the display is heightened and the rack needs to stop moving, the rotating block is externally rotated to enable the rotating block to be in a vertical state, the ratchet wheel is in contact with the pawl, the motor is stopped to rotate, the pawl enables the ratchet wheel not to reversely rotate along with the gear, and the pawl brakes the ratchet wheel, so that the gear stops rotating, the rack stops moving, and the position of the display is stable; when the position of the display is lowered, the rotating block is in a horizontal state before starting, the ratchet wheel is not in contact with the pawl, when the rack needs to stop moving, the rotating block is externally rotated to enable the rotating block to be in a vertical state, the ratchet wheel is in contact with the pawl, the motor is stopped to rotate at the moment, the pawl enables the ratchet wheel not to reversely rotate along with the gear, and the pawl brakes the ratchet wheel, so that the gear stops rotating, the rack stops moving, and the position of the display is stable. The brake switch can make the gear stall when the motor rotates, prevents that the gear from continuing to rotate under the inertia effect and making the rack remove after the motor stops, influences the height of display.

Furthermore, the connecting part is fixedly connected with the inner wall of the connecting plate through a second spring. The vibration of the connecting part in the ascending or descending process can be slowed down, so that the connecting part is stable.

Further, the surface of the connecting part is provided with a baffle. When the display is disassembled from the keyboard body, the blocking cover is placed on the surface of the connecting part, so that dust is prevented from falling into the connecting part, and the connection stability of the display and the keyboard body is prevented from being affected.

Furthermore, the surface of the connecting plate is provided with a rubber pad, the connecting plate and the display shell are made of hard materials, and the rubber pad can reduce friction damage between the connecting plate and the display shell.
