to the above problem, the utility model aims at providing an automatic rising button that keyboard space took when can effectively reduce to accomodate.
In order to realize the technical purpose, the utility model discloses a scheme is: an automatic lifting key comprises an X balance frame, a reset mechanism, a key seat and a key, wherein the key is arranged above the key seat, and the X balance frame and the reset mechanism are arranged between the key and the key seat.
Preferably, a movable plate capable of moving horizontally is further arranged below the key base, a buckle is arranged on the movable plate, a convex column is arranged on the X balance frame, and the buckle corresponds to the convex column;
One end of the movable plate is also connected with a traction mechanism.
Preferably, the buckle is a hook-shaped structure with a triangular groove, the front section of the convex column is an arc-shaped plate structure for transition, the tail section of the convex column is a trapezoidal plate structure, and the trapezoidal plate structure and the buckle are tightly buckled during compression.
Preferably, the PCB below the key seat is correspondingly provided with an induction module, and the induction module is a membrane switch or a photoelectric switch or a Hall switch.
preferably, the return mechanism is a spring or a silica gel elastic member.
The utility model has the advantages that the automatic lifting key can automatically expand the key when the cover is opened and automatically contract the key when the cover is closed, the space height is less occupied when the cover is closed, a notebook or a Bluetooth keyboard can be thinner and more portable, and good knocking touch feeling is kept when the automatic lifting key is used; meanwhile, the traction mechanism is automatically released when the cover is opened, so that the habit of daily operation is met, and additional operation is not required; when the cover is closed, the cover is pulled in groups, so that the force is more reasonable when the cover is closed, the cover closing action is smoother, and the traction mechanism is not easy to damage.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-6, an automatic lifting key comprises an X balance frame 3, a reset mechanism 2, a key base 2 and a key 1, wherein the key 1 is arranged above the key base 2, the X balance frame 3 and the reset mechanism 4 are arranged between the key 1 and the key base 2, a movable plate 5 capable of moving horizontally is further arranged below the key base 2, a buckle 6 is arranged on the movable plate 5, a convex column 7 is arranged on the X balance frame 3, and the buckle 5 corresponds to the convex column 7; one end of the movable plate 5 is also connected with a traction mechanism.
In order to facilitate automatic resetting of the key, the resetting mechanism 2 is a spring or a silica gel elastic part.
in order to let the horizontal right side of fly leaf move the back can be stable fix the X balancing stand, perhaps can loosen the X balancing stand after the horizontal left side moves, buckle 6 is the structure of colluding of taking the triangular groove, the 7 anterior segments of projection are for being used for the arc structure of transition, and 7 middle sections of projection are horizontal structure, 7 tail sections of projection are the trapezoidal plate structure, during the compression, trapezoidal plate structure is inseparable with the buckle lock. The arc plate structure can let smooth the passing through of buckle, moves to the assigned position when the activity level right side, buckle and trapezoidal plate structure block, and X balancing stand also becomes compression state from the state of extending this moment.
The lifting key can be adapted to various induction modules and is suitable for a thin film keyboard, a photoelectric mechanical keyboard and a Hall switch keyboard. The PCB 9 below the key base 2 is correspondingly provided with an induction module 8, and the induction module is a film switch or a photoelectric switch or a Hall switch.
When the X-shaped balance frame is used, the cover is in a cover closing state, the X-shaped balance frame is folded and contracted, and the key occupies a small space and is small in height; the cover is opened, the traction mechanism is loosened, the X balance frame is automatically unfolded, and the key is restored to the normal height. According to the notebook cover closing method and device, the movable state of the X balance frame of each key can be controlled, so that the notebook cover can be kept in a thin state, and the keys can be restored to a normal state after the notebook cover is opened. The overall height of the keys in the compressed state can be less than 3.5cm, and the space height can be saved by about 30% compared with the existing notebook keyboard.
The method comprises the following specific steps:
Firstly, when a cover body or a handle is closed, a key is in a compressed state, the cover body or the handle of the equipment is opened, the cover body or the handle releases a traction mechanism, and a movable plate is driven to move under the action of the elasticity of the key;
Secondly, after the movable plate is displaced, the locking state between the movable plate and the X balance frame is released, the X balance frame is unfolded under the action of a reset mechanism, and the keys are restored to the normal height;
And thirdly, slowly closing the cover body or the handle, pulling the movable plate by the traction mechanism under the action of the cover body or the handle, moving the movable plate back to the initial position, and clamping the movable plate with the X balance frame to change the key into a compressed state.
One traction mechanism can drive a plurality of movable plates to move. Because a keyboard has a plurality of keys, a traction mechanism drives the plurality of keys to be easier to operate. The cover body or the handle can drive a plurality of traction mechanisms, and different traction mechanisms are driven according to different rotation angle positions.
Generally, a key press requires more than 45 grams of pressing force, a side press requires more pressing force, and a keyboard generally has 66-104 keys, which require excessive pressing force if pressed simultaneously. The applicant then believes that it is necessary to pull the keys in groups, for example, keys 1-20 when the cover or handle is rotated 0-15, keys 21-40 when 15-30, and so on. Therefore, the cover closing action is smoother, and the traction mechanism is not easy to damage.
The automatic lifting key can be automatically unfolded when the cover is opened, and can be automatically retracted when the cover is closed, so that the space height is smaller when the cover is closed, a notebook or a Bluetooth keyboard can be thinner and easier to carry when not used, and a good knocking touch feeling is kept when the notebook or the Bluetooth keyboard is used; meanwhile, the traction mechanism is automatically released when the cover is opened, so that the habit of daily operation is met, and additional operation is not required; when the cover is closed, the cover is pulled in groups, so that the force is more reasonable when the cover is closed, the cover closing action is smoother, and the traction mechanism is not easy to damage.
The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
