Abstract

The utility model relates to a brake hinge, particularly a brake hinge which is arranged on a pivot joint point of a base plate and a cover plate. Both ends of an intermediate shaft are respectively sheathed with a sleeve pipe which rotates on the original place, and the outer end of each sleeve pipe is provided with an outer shaft. A spring is arranged between the intermediate shaft in the sleeve pipes and each outer shaft, and the both ends of the intermediate shaft are respectively provided with a levorotatory spring and a dextrorotatory spring. The cover plate can be adjusted to be positioned on any angle to be positioned.

Description

Brake hinge

The utility model relates to a kind of Brake hinge, especially refer to the Brake hinge on a kind of pivoting point that is installed in base and cover plate, connect outer shaft at jackshaft two ends with spring, when this cover plate is raised, spring must be rolled up and lean against on jackshaft and the outer shaft, and powerful steadiness must be arranged, the cover plate adjustment can be positioned on desire location arbitrarily angled.

Press, general laptop computer is made up of main frame and display, and this display is hubbed on the side of main frame, and this display must upwards be raised when using; And, can be convenient to computer user monitor scope owing to after this display raises, must be positioned on a certain angle; And if will cover display on main frame the time, this display must can slowly cover, and can avoid display to clash into main frame and causes damage; Therefore, in the articulated section of main frame and display, must install hinge with location and damping action.

And known being installed on the laptop computer, the hinge with location and damping action is set with a spring between centre drawer hinge bracket and centre drawer hinge, and the rotating shaft between centre drawer hinge bracket and centre drawer hinge, apply thick oil, and must borrow spring and thick oil, reach the effect of damping and location; But this thick oil can volatilize over time gradually, and reduces the effect of damping, and the situation that can cause the display location to be difficult for equally is so its application life is shorter.

Because of the damping number of thick oil and nisi definite value, when this display was raised, this display there is no the method location again, and bigger when raising angle backward under the square neck, therefore, and its less stable and cause user's puzzlement.

In addition, filling elastomeric material between the rotating shaft of centre drawer hinge bracket and centre drawer hinge, and can be by means of the friction between this elastomeric material and the rotating shaft, reach the effect of damping and location, yet this elastomeric material can be because of wearing and tearing, and reduce the effect of its damping, and after the damping reduction in a single day, promptly can influence the effect of location, have above-mentioned puzzlement in the use equally.

Again with the hinge of elastomeric material as damping and positioning action, because of elastomeric material must have suitable volume, can reach above-mentioned effect, so can't reduced volume, make that the articulated section volume of the main frame of laptop computer and display is bigger, thereby can't reach thin thickness, purpose that volume is little.

The purpose of this utility model provides a kind of Brake hinge, connect outer shaft at jackshaft two ends with spring, spring must be rolled up and lean against on jackshaft and the outer shaft when this cover plate was raised, and powerful steadiness must be arranged, and the cover plate adjustment can be positioned on desire location arbitrarily angled.

The purpose of this utility model is achieved in that a kind of Brake hinge, it is characterized in that: the main sleeve pipe that respectively is set with original place rotation at the two ends of a jackshaft, and this sleeve pipe outer end places an outer shaft again, and device has a spring between jackshaft in sleeve pipe and the outer shaft, and is respectively left-handed spring and dextrorotation spring at the two ends of jackshaft.

Owing to adopt such scheme: the cover plate adjustment can be positioned on desire location arbitrarily angled.

For making the utility model in detail clear and definite more, cooperate following each diagram to describe in detail as the back now:

Fig. 1 installing stereogram of the present utility model

Fig. 2 assembling view of the present utility model

Fig. 3 a kind of action embodiment schematic diagram of the present utility model.

Fig. 4 another kind of action embodiment schematic diagram of the present utility model.

At first, see also Fig. 1 and Fig. 2, the utility model mainly respectively is set with the sleeve pipe 2 that rotate an original place in the two ends of a jackshaft 1, and these sleeve pipe 2 outer ends place an outer shaft 3 again, device has a

spring

4a, 4b between jackshaft in sleeve pipe 21 and the outer shaft 3 again, and is respectively left-handed spring 4a and dextrorotation spring 4b at the two ends of jackshaft 1.

According to above-mentioned structure, this two outer shaft 3 must be separately fixed at articulated section 51a, the 52a of a base 51 and cover plate 52, as shown in Figure 1.

This left-handed spring 4a and dextrorotation spring 4b be not when stressing again, its external diameter tolerance is slightly less than the id tolerance of sleeve pipe 2, and be the state of loose fit, and the id tolerance of left-handed spring 4a and dextrorotation spring 4b, be slightly less than the external diameter tolerance of outer shaft 3 the inners again, and be friction tight state, when making this cover plate 52 raise or cover, must borrow the frictional force that fit tolerance produced between jackshaft 1, sleeve pipe 2, outer shaft 3 and spring 4a, the 4b, cause

spring

4a, 4b to reverse forward or backwards.

Therefore, when cover plate 52 covered on base 51, this left-handed spring 4a and dextrorotation spring 4b were reversed, and made to produce a gap e1 between its internal diameter and the outer shaft 3, so this left-handed spring 4a and dextrorotation spring 4b do not roll up on the external diameter that leans against outer shaft 3, as shown in Figure 3; And when raising cover plate 52, this left-handed spring 4a and dextrorotation spring 4b turn-back, make and produce a gap e2 between its external diameter and the sleeve pipe 2, and this left-handed spring 4a and dextrorotation spring 4b volume lean against on the external diameter of outer shaft 3, as shown in Figure 4, so can borrow left-handed spring 4a and dextrorotation spring 4b volume to lean against on outer shaft 3 and the jackshaft 1, reach the purpose of cover plate 52 location.

This jackshaft 1, outer shaft 3 must be borrowed the fit tolerance between left-handed spring 4a, dextrorotation spring 4b and the sleeve pipe 2 and cause damping again, make this cover plate 52 slowly be raised or cover.

And because the utility model is borrowed left-handed spring 4a and dextrorotation spring 4b, and reach the purpose of damping and location, therefore increased the service life, and got reduced volume, and can be by means of the left-handed spring 4a and the dextrorotation spring 4b of the different torsion that change the outfit, to reach the size of corrective action power.

In addition, the utility model is implemented on the laptop computer, and the display of laptop computer is reached as above-mentioned effect.

Comprehensive the above, the disclosed structure of the utility model does not in the past have, and can reach above-mentioned effect really, manages the important document that has possessed novel patent, files an application novel patent in accordance with the law.
