Abstract

The utility model provides a hinge for a turnover cover of an electronic product. The hinge comprises a fixing shaft, a rotating shaft, an exterior container, a shaft seat and a spring. The end part of the exterior container is provided with a first step and a second step for limiting the rotating angles of the rotating shaft, while the rotating shaft is provided with bulges matched with the first step and the second step. The utility model designs a self limiting device of the hinge, which can limit the moving range of the hinge on the basis of not changing the structure of the moving principle of the hinge and not increasing the appearance size of the hinge. Even if the casing is stressed to deform, the hinge can limit the self rotating angle, and avoids entering into a ''dead position'', thus solving the potential dead lock phenomena of a telephone.

Description

Electronic product is renovated hinge

Technical field

The utility model relates to the hinge of renovating of electronic product.

Background technique

The folding movement that folding mobile telephone machine etc. has the electronic product of renovating is a driver part by the rotating shaft hinge generally, renovate hinge and generally comprise stationary axle, rotating shaft, axle bed, axle bed is limited in the outer container and slidably, be provided with between axle bed and outer container along the axial spring of outer container, rotating shaft is arranged on the opposite side of axle bed, stationary axle passes rotating shaft, axle bed and is connected the opposite side of outer container, and the opposing side of rotating shaft and axle bed is provided with the configuration that matches, such as camming surface.When rotating shaft was rotated, relative displacement upwards took place in week in rotating shaft and axle bed, and cooperated and be positioned on new rotation angle by the configuration on their opposing side.

Hinge can 360 ° rotation arbitrarily, the angle that folding mobile telephone is opened is reached by the limit stoper of casing, is generally 160～175 °.When design in the past, often the open angle with hinge is designed to 60～90 °, promptly renovate open to 60～90 ° after, release energy and open automatically and renovate by the accumulating mechanism in the hinge.At present, consider that the Consumer opens the convenience of mobile phone, begun to have open angle with hinge to be decided to be design about 35 °.This hinge is because the narrow limitation of cam design, can not 360 ° of rotation arbitrarily, there be " dead center position " in the motion.Enter when hinge is worked " dead center position ", it is strict that the making required precision of the limit stoper of casing becomes.But because casing generally uses the stressed non-deformability of plastic material poor, reach requirement even if make precision, be subjected under the excessive external force effect, still can cause the casing distortion, rotating shaft enters " dead center position ", and mobile phone can't be opened then.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of electronic product that enters " dead center position " when avoiding work and renovates hinge.For this reason, the utility model is by the following technical solutions: it comprises stationary axle, rotating shaft, outer container, axle bed, spring, the end of described outer container has been provided with the first step and the second step of restriction rotating shaft rotation angle effect, and described rotating shaft is provided with the projection that cooperates with first step and second step.Owing to adopt the technical solution of the utility model, the utility model has designed the limit stoper of a kind of hinge self, can on the structure of not changing original hinge movement principle, on the basis that does not increase hinge boundary dimension, can the range of movement of hinge be limited.Even if behind the casing stress deformation, hinge can limit the rotation angle of self, avoids entering " dead center position ".Thereby solved potential phone deadlock phenomenon well.

Embodiment

With reference to accompanying drawing 1-5.The utility model comprises stationary axle 1, rotating shaft 2, outer container 3, axle bed 4, spring 5.Described stationary axle 1 passes rotating shaft 2, axle bed 4, spring 5 and is connected with outer container.Rotating shaft 2 and axle bed 4 are respectively equipped with the

camming surface

20,40 that matches, and axle bed 4 is limited in the outer container, and outer container is done axial motion relatively.

The end of described outer container has been provided with the first step 31 and the second step 32 of restriction rotating shaft rotation angle effect, and described rotating shaft is provided with the projection 23 that cooperates with first step and second step.

With reference to accompanying drawing 3,4.Described protruding 20 extending circumferentiallies along rotating shaft, and, first end 21 that cooperates with first step and second end 22 that cooperates with second step be provided with; The end of described outer container has and protruding corresponding groove 33 at first step.Like this, can make things convenient for the installation of hinge.

With reference to accompanying drawing 3,4.The outside of second end of described projection has unfilled corner 220.Described outer container is being provided with first step and the second step place is the opposite side shape, like this, not only make and to be convenient to the outer container limit mounting in electronic product, be convenient to the circumferentially spacing of axle bed, and make second step apart from the distance of outer container center line radius less than outer container, so that utilize triangle rotation principle, the external diameter that makes second end still can cooperate with second step under the situation less than the radius of outer container.

Described groove 33 also can be used for the circumferentially spacing of axle bed, and as shown in the figure, axle bed is provided with the circumferential positioning key 41 of the axle bed that is in the described groove 33.

Described outer container end forms the central angle of low that section of step and spends less than 180, and first end of described projection is or/and second end is a hypotenuse, so that cooperate better with first step and second step.

Described rotating shaft and axle bed are the metalwork that is surrounded by flexible material with the outer container contacting point, like this, can guarantee that the camming surface between rotating shaft and the axle bed cooperates employing metal covering contact matching, thereby more wear-resisting, longer service life, simultaneously, rotating shaft is contacted with axle bed and outer container are flexible, reduce noise.

As shown in Figure 5, rotating shaft 100 and axle bed 200 relatively rotate, and working surface is the B face farthest.After if rotating shaft enters the A face of axle bed, because A face slope is far longer than the B face, will be stuck, can't get back to the B working surface.Here it is so-called " dead center position ".In the utility model, projection 23 stopped that make that the rotation angle of rotating shaft is accurately limited, rotating shaft can not enter the A face of axle bed by first step and second step.
