The technical field is as follows:

the invention relates to the technical field of notebook computer reinforcing devices, in particular to a screen turning limiting protection device for reinforcing a notebook computer.

(II) background technology:

at present, the reinforced notebook computer is mostly used in various severe environments such as large peripheral high-low temperature difference, much sand and dust, continuous vibration and even impact, and the like, so that corresponding protective measures should be taken in the aspects of system planning, electrical performance, mechanical structure and the like. The reinforced notebook shell is usually formed by processing metal parts, the weight of the reinforced notebook shell is far greater than that of a common civil notebook, the part of the screen is connected with a box body of the whole notebook through two groups of damping hinge shafts, and the turning angle and the fixation of the screen are all realized by the damping hinge shafts.

However, this approach also has unavoidable safety hazards:

1. the weight of the reinforced notebook screen computer is completely borne by the damping hinge shaft, the opening angle of the notebook computer cannot be fixed, and when the notebook screen computer is in a bumping and vibrating state, the opening angle of the screen can change before and after vibration;

2. the vibration is resisted by the damping hinge shaft all the time, so that the aging of the damping hinge shaft is easy to accelerate, the damping is gradually reduced, and the fixing function of the screen of the notebook computer is lost over time;

3. when extreme conditions occur, such as the rear of the screen being impacted, the screen may close directly, pinching both hands of the operator, and be unsafe.

In order to solve the problems, the safety and the durability of the reinforced notebook are improved, and the development of the reinforced notebook screen turning limiting protection device is necessary.

(III) the invention content:

the invention aims to provide a screen-turning limiting protection device for a reinforced notebook computer, which can make up for the defects of the prior art and is a limiting protection device with simple structure and easy realization.

The technical scheme of the invention is as follows: a screen-turning limit protection device for a reinforced notebook computer is characterized by comprising a guide rail shaft, a steering shaft, a toggle switch, a spring and a coaxiality guarantee shaft; the screen turning limiting protection device is arranged at the joint of the screen of the notebook computer and the lower case; a screen front panel and a screen rear cover plate are coated outside the whole screen turning limiting protection device; the guide rail shaft is fixedly arranged on a screen front panel of a notebook computer screen; the steering shaft is fixedly arranged on the lower case of the screen of the notebook computer; the guide rail shaft and the steering shaft are connected through a coaxiality guarantee shaft; the toggle switch is arranged on the guide rail shaft.

The steering shaft is a key shape structure with an angle at one end, and can be matched with the opening on the toggle switch to lock the screen when the screen is turned to a preset angle.

The angle of the key profile of the steering shaft is 105-120 degrees.

The guide rail shaft is fixed on a screen front panel of a notebook computer screen; the steering shaft is fixed on the lower case of the notebook computer screen; the guide rail shaft and the steering shaft are coaxially arranged with a damping hinge shaft arranged on a screen of the notebook computer and are used for ensuring that the guide rail shaft can rotate along with the screen when the screen of the notebook computer is turned over, and further an angle difference is generated between the guide rail shaft and the steering shaft so as to finish limiting and fixing.

The coaxiality ensures that the size of a fit clearance between the shaft and the guide rail shaft and between the shaft and the steering shaft is within 0.05 mm.

The toggle switch is provided with an opening for realizing the matching connection with the key appearance of the steering shaft and the guide rail shaft when the notebook screen is opened at a certain angle, thereby playing the role of limiting and fixing the reinforced notebook screen.

The opening on the toggle switch is positioned in the middle of the toggle switch, the fit clearance between the opening and the guide rail shaft and the steering shaft is 0.05mm-0.10mm, and the display screen is guaranteed not to generate large displacement after being limited and fixed.

A reserved gap is reserved between the toggle switch and a screen front panel of the notebook screen, the gap is larger than 0.1mm, and extra sliding friction force is prevented from being added to the toggle switch due to stress when the toggle switch is used.

The diameter of the spring is not suitable to be too thin, the value range is 0.5mm-0.8mm, so that when the toggle switch is used for limiting the overturning of the notebook screen, a collision confirmation sound can be emitted, and the diameter of the spring is 0.8mm in the case.

Guide rail axle and steering spindle, dial button switch, spring and axiality guarantee that the axle all adopts stainless steel, guarantees the requirement of intensity and rigidity, compromise experimental requirements such as vibrations impact, salt fog, mould simultaneously.

The invention has the advantages that: (1) the structure is small and exquisite, the specific size of the notebook can be adjusted according to the space of different reinforced notebooks, and the notebook is convenient to adapt to various reinforced notebooks; (2) the integration level of the function and the action of the parts is high, wherein the movement direction of the toggle switch is the unlocking direction, so that the transmission connection among the parts is reduced, and the reliability is enhanced; (3) the function is independent, can install inside the display screen completely, avoids producing the motion relation with external structure spare, can not in use fish tail external structure spare lacquer painting.
