Description
Technical field
The present invention relates to notebook computer field, especially a kind of can stable regulation angle can automatically lock the notebook computer of display screen part.
Background technology
Notebook computer extensively replaces desk computer and is applied to pc domain.And the experience that can improve user is unlocked for being automatically adjusted and locking of display screen.But, drive system for this adjustment and unblock locking generally requires the accommodation space that increase is extra, for notebook computer, the increase of this change often resulting in outward appearance and volume, it is particularly susceptible the size increasing the protuberance that display screen articulated position place extends back.This is disadvantageous for the overall appearance of computer and serviceability.The pattern driven by traditional gear motor is then difficult to accurately regulate at a slow speed the angle of display screen, and the problem of the aspect such as control performance cost due to drive motor, it is easy to cause computer costs to raise and reliability is not high.
Summary of the invention
It is an object of the invention to provide a kind of can stable regulation angle can automatically lock the notebook computer of display screen part, it can overcome defect of the prior art.
nullA kind of according to the present invention can stable regulation angle can automatically lock the notebook computer of display screen part，Including body part and the display screen part that is connected with described body part，Wherein，Described body part includes housing parts，The inner chamber of described housing parts is fixedly installed for being rotatably mounted the coaxial driving pinion being connected and the first axle driving gear wheel and the second axle for being rotatably mounted the driven pinion fixing to be connected respectively with two fixed legs in the bottom being provided separately of described display screen part being in identical level height with described first axle，Wherein，Described driving gear wheel engages with described driven pinion and quantity respectively two，It is arranged at the both sides of described driving pinion，The downside of described driving pinion be fixedly mounted on the rack member moved left and right on the upside of block and engage，The described bottom moving left and right block is provided with sliding chamber and is slidably matched in order to the head with screw rod，It is fixedly connected with elastomeric element between the inner in described head and described sliding chamber，Described screw rod with penetrate in hollow shaft motor and by the screw shell threaded engagement of thrust bearing and described housing parts axial restraint it is thus possible to move left and right，The side that described screw rod is relative with described head is fixed with lock drive portion by connecting rod and is connected，The upper outside of described lock drive head be provided with lock drive inclined-plane in order to when described screw motion in right positions by described display screen partial turn to closure state time engages with the inboard portion of slide lock rationed marketing thus the Outboard Sections of described slide lock rationed marketing overcomes top be pressed between described interior section and Outboard Sections intermediate flange on and described slide lock rationed marketing is biased to the inside so as the biasing force of the unblock biasing spring unlocked and be pushed out of described housing parts and the latched position that arrives，Engage with the lock hole with the top end of described display screen part，Thus the closure state of described display screen part is locked，The end face of the inboard portion of described slide lock rationed marketing is provided with roller，Described roller coordinates in order to move in described lock drive portion to roll with described lock drive inclined-plane when right positions，To reduce frictional force，Make operation more stable；Wherein, the longitudinal direction of described slide lock rationed marketing is in and is deflected outward by the direction of a sharp angle A from vertical direction so that oblique cutting enters the lock hole of the top end of described display screen part and realizes the locking pivoted；Wherein, described driven pinion is identical with the radius of driving pinion, is the half of the radius of described driving gear wheel；Wherein, when described display screen is partially in the plumbness relative to described body part, the position of engagement of described driving pinion and described rack member is in the centre of described rack member, and the length of described rack member is arranged to so that described display screen part distinguishes positive and negative rotation degree from described plumbness；The left end pars intramuralis of described housing parts is provided with extreme position limit switch, described extreme position limit switch contacts with the described block that moves left and right when described display screen part is from described plumbness 90-degree rotation counterclockwise, and signal is passed to described hollow shaft motor, described hollow shaft motor is just out of service after receiving signal.
By the present invention, engage with gear by being threaded bar rack member, it is possible to driven by motor and the accurate pivotal movement slower speeds controlling display screen.Owing to the driving of screw rod tooth bar pattern needs the bigger accommodation space of longitudinally, this is realized at organism bottom by longitudinal extension；And tooth bar screw rod in motor process owing to relating to threaded engagement and the mobile space problem of gear engagement, it is therefore desirable to the reserved bigger activity space in both sides, this brings challenges to the size reduction of computer.By arranging the size gear train engaged with the fixed gear of display screen section bottom, it is capable of the interior shifting of rack and pinion meshing point, thus making full use of the inner space activity space for tooth bar of computer casing, and have employed the coaxial pattern of size gear simultaneously and engage with little gear, fully shorten and reach display screen pivot turnback or tooth bar displacement 90 degree required；That is, size Double-gear arranges with concrete two-to-one size and engages with little gear, can be little tooth radius by moving 3r(r in meshing point compared with the pattern directly adopting tooth bar little gear engagement fixed with display screen by meshing point) distance, setting by size gear coaxial module, when making to be turn 90 degrees by display screen pivot, the pivoting angle of driving pinion is 45 degree, therefore the displacement of tooth bar is (∏/4) × r, reserved activity space distance adds tooth bar length thereof distance for (∏ r/2), is about 1.5r.Therefore above-mentioned inset is from the longitudinal size requirement that can fully meet tooth bar.And by be arranged at this tooth bar linkage stop pin drive division, it is possible to be automatically locked when display being switched to make position, and can when needs pivot is opened automatic unlocking.This stop pin is be tilted towards outer orientation upwards, it is possible to the stop pin directly entered with oblique cutting when the top edge of display screen is not provided with corner protuberance substantially coordinates thus the locking that realizes in pivot be easy to unblock.It is connected by setting the elasticity between screw rod with rack drives block, it is possible to provide cushion space for locking and unblock, it is ensured that unlocked rear indicator screen and started to pivot.Whole device can reliability service and also easy to use, there is good Consumer's Experience.
