Description

A kind of serial verb construction for being used to open and close electronic equipment

Technical field

Electronic equipment machinery technical field is the utility model is related to, is set more particularly, to one kind for opening and closing electronics Standby serial verb construction.

Background technology

Existing electronic equipment, such as notebook computer, being generally designed with host computer system end can relative host computer system The display screen end of folding is held, so, display screen end can be both raised in working condition, can be closed again in transportation aobvious Display screen curtain end.To complete aforementioned operation, by taking notebook computer as an example, system end and screen display end are connected from dual-axis pivot device more, It can enable screen display end raise as action axle center using the pivot device or be closed in system end downwards upwards, and can also be with such as 360 ° of wide-angle bending mutually builds up tabular use state.

To improve the efficiency of movement raised and closed, dual-axis pivot device is set to twin shaft with dynamic structure, most common mode more That shaft gear is provided with first rotating shaft and the second rotating shaft, and between first rotating shaft and the second rotating shaft be provided with can be with two bars The idler gear of body gear while bridle joint, so, when any one axis of rotation in first rotating shaft and the second rotating shaft, then can lead to Crossing idler gear drives another rotating shaft to produce gearing.Raised or closure state to keep stable, otherwise it is by first Positioning and torsion component are set in rotating shaft and the second rotating shaft to realize the locking effect to dual-axis pivot device, otherwise it is that positioning is set And on the basis of torsion component, locking mechanism is set up between first rotating shaft and the second rotating shaft, for the former, detent force is weaker, For the latter, installation locking structure can not only increase the complexity of unitary construction, and action executing in narrow and small installing space Stabilization and reliability be also not easy to be controlled by.

Utility model content

The purpose of this utility model is to overcome the above mentioned problem of prior art, there is provided one kind is set for opening and closing electronics Standby serial verb construction, by the design of tight component, it can be achieved to the first pivot and the locking action of the second pivot, so, can have Effect avoids screen display end and system end that unintentional rotation occurs after raising.Latch assembly and the second fixed plate are realized by connection component Between connection, it can not only realize the installation of latch assembly, it is also ensured that the stability and reliability of action executing.

The purpose of this utility model is achieved through the following technical solutions：

A kind of serial verb construction for being used to open and close electronic equipment, including the first pivot and the first pivot axis parallel are set The second pivot, positioning torsion component and transmission component, in addition to latch assembly and the component that is connected；

Latch assembly includes crimping plate, movable part and elastic component；

The upper and lower ends of crimping plate are connected on the first pivot with the second pivot, and the first pivot and the second pivot can Opposing crimp plate is circumferentially rotated and can not moved axially, and is crimped and is provided with the first concave on plate；

Movable part has shaft sleeve part and extension, and shaft sleeve part is interlocked and is set on the second pivot, and shaft sleeve part can be along second The axial movement of pivot；

The second concave that can coordinate with the first concave is provided with shaft sleeve part, elastic component is connected on the second pivot simultaneously Shaft sleeve part is acted on to cause：Second concave and the concavo-convex combination of the first concave；

First pivot one end is connected with the first fixed plate, and the one end of the second pivot is connected with the second fixed plate, extension Portion is connected in the second fixed plate by the component that is connected；

Rotating the second pivot can make：Second concave is moved towards the direction away from the first concave, and shaft sleeve part is progressively pressed Contracting elastic component, extension move axially along the second pivot.

In the utility model, the first fixed plate can be connected with screen display end, and the second fixed plate can be connected with system end.Transmission group Part is used to transmit kinetic energy and changes the direction of kinetic energy, when the first pivot rotates, then the second pivot can be driven to occur reversely to turn It is dynamic, in this way, screen display end and the efficiency of system end turnover can be accelerated.To avoid impurity from entering the first pivot and the second pivot, can set Sheath is equipped with to screen to transmission component and positioning torsion component.Positioning torsion component can be not only used for limiting crimping plate and transmission The position of component, also certain torsion and detent force can be provided for the first pivot and the second pivot, but position the lock of torsion component Tailor-made use is weaker, easily makes the first pivot and the second pivot that unintentional rotation occur, and then, screen display end and system end turnover shape can be influenceed The stability of state.Therefore, the utility model has additional latch assembly, it can effectively lock the second pivot and the first pivot is relatively fixed The circumferential position of position torsion component, avoids screen display end that unintentional rotation occurs with system end.

During the utility model zero-bit state, namely when screen display end is closed in system end, the second concave and first concavo-convex Take turns in the concavo-convex state combined under the supporting role of elastic component, at this moment, the second concave is also at concavo-convex near first The position of wheel, thus, hold out against effect of the elastic component to shaft sleeve part is in most weak state.At this moment, rotate screen display end, then can light band Dynamic first pivots and interlocks the second pivot and rotate backward, and when second pivots, shaft sleeve part can then drive second Rotation relative to the first concave occurs for concave, and in the rotation process, the second concave can gradually disengage and the first bumps The concavo-convex of wheel is combined and moved away from the direction of the first concave, so, then can drive shaft sleeve part also away from first The direction movement of concave, can then be given shaft sleeve part larger reaction force, the reaction force then may be used by the elastic component compressed Effectively holding out against the second pivot avoids its from occurring unintentional rotation, then the gearing by transmission component, then the also pivot of lockable first The position of axle avoids it that unintentional rotation occurs.Wherein, the setting of connection component can be both realized between shaft sleeve part and the second pivot Interlock, axial movement of the shaft sleeve part with respect to the second pivot can be realized again.

The utility model realizes the connection between latch assembly and the second fixed plate by connection component, and it can not only be realized The installation of latch assembly, it is also ensured that the stability and reliability of action executing.Wherein, can be real by the design of latch assembly Now to the first pivot and the locking action of the second pivot, so, screen display end and system end can be effectively avoided to be anticipated after raising Outer rotation.It can be seen that the utility model has the advantages of simple in construction, stable and service life is long.
