Description

A kind of mobile electronic terminal biaxial hinge and mobile electronic terminal

Technical field

This utility model relates to the two-shaft hinge mechanism on mobile electronic terminal and mobile electronic terminal.

Background technology

At present, for mobile electronic terminals such as such as notebook computers, a lot of employings have the hinge of friction structure, to realize stopping positioning function at any time at any time, and this hinge also occur can the structure opened of 360 ° of upsets, this structure generally requires gear drive and realizes bidirectional open and closedown, the mobile electronic terminals such as the notebook computer applying this kind of hinge often have 180 ° of needs flattened, but the lid once mobile electronic terminal is different with main frame thickness, its flattening itself has several selection form, although now hinge is open to flatten angle, but required selection form state might not be between lid and main frame, discomfort is brought to use.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of mobile electronic terminal biaxial hinge, it is possible to tackles the occasion that the lid of mobile electronic terminal is different with main frame thickness, and can be opened to required state.To this end, this utility model is by the following technical solutions:

A kind of mobile electronic terminal biaxial hinge, including the first axle and the second axle, gear drive is connected between described first axle and the second axle, make the first axle and the second axle energy synchronous backward rotate, it is characterised in that described gear drive be accelerating gear drive mechanism or reduction gear mechanism or:

Described gear drive is for when biaxial hinge is opened to the open angle of design by gear drive transmission, and the gap of its tooth being in the position of engagement is more than the gap when being engaged of other tooth about.

Further, described gear drive is accelerating gear drive mechanism, and:

Described gear drive is for when biaxial hinge is opened to the open angle of design by gear drive transmission, and the gap of its tooth being in the position of engagement is more than the gap when being engaged of other tooth about.

Another technical problem to be solved of this utility model is to provide a kind of mobile electronic terminal applying above-mentioned biaxial hinge.To this end, this utility model is by the following technical solutions:

A kind of mobile electronic terminal, it is characterised in that described mobile electronic terminal includes lid and main frame, and lid is different with the thickness of main frame, described lid and main frame are connected by any one biaxial hinge above-mentioned.

Owing to using the technical solution of the utility model, for covering the mobile terminal different with main frame thickness, gear acceleration and deceleration and the control in gap can be passed through, lid and main frame are produced synchronize the most synchronized adverse movement pattern and make to eventually arrive at the position of anticipation, or pass through or pass through gear clearance further, and when making to be opened to design attitude by gear-driving hinge, rely on the gap of gear, make lid or main frame can more turns of small angles and reach required state, thus tackle, by the scheme of simple in construction, the occasion that the lid of mobile electronic terminal is different with main frame thickness, and enable mobile electronic terminal to reach required state.

Detailed description of the invention

Referring to the drawings 1,2,3.Mobile electronic terminal biaxial hinge provided by the utility model, including the first axle 1 and the second axle 2, connects gear drive between described first axle 1 and the second axle 2, make the first axle 1 and the second axle 2 to rotate by synchronous backward.

Described gear drive can use the bevel gear transmission 3-1 shown in Fig. 1, the spiral gear drive mechanism 3-2 shown in Fig. 2, or the Spur Gear Driving mechanism 3-3 shown in Fig. 3.

Described mobile electronic terminal includes covering 101 and main frame 102, and lid 101 is thinner than main frame 102, and described lid and main frame are connected by any one biaxial hinge above-mentioned.

As shown in fig. 4 a, in this embodiment, 180 ° of flat of the bottom surface alignment that design open angle is lid 101 and main frame 102 of mobile electronic terminal, now can use accelerating gear drive mechanism, namely cover that connected first axle rotating speed is fast and the connected main shaft speed of main body is slow, so, when being opened to Fig. 4 a state, although lid 101 and main frame 102 are in 180 ° of flat, but by accelerating gear drive mechanism, the angle that first axle rotates is more more than the second axle, and the open angle of hinge has exceeded 180 °.

As shown in Figure 4 b, in this embodiment, 180 ° of flat of the end face alignment that design open angle is lid 101 and main frame 102 of mobile electronic terminal, now can use reduction gear mechanism, namely cover connected first axle rotating speed main body connected main shaft speed block slowly, so, when being opened to Fig. 4 b state, although lid 101 and main frame 102 are in 180 ° of flat, but by reduction gear mechanism, the angle that first axle rotates is fewer than the second axle, and the open angle of hinge is less than 180 °.

Above many gyrations and few gyration also can realize by changing the gap of tooth, namely:

Described gear drive is for when biaxial hinge is opened to the open angle of design by gear drive transmission, and the gap of its tooth being in the position of engagement is more than the gap when being engaged of other tooth about.In the case of such as Fig. 4 a, when two axles of biaxial hinge rely on the motion of gear drive synchronous backward to make biaxial hinge be opened to 180 °, the gap of its tooth being currently at engagement is more than the gap when being engaged of other tooth about, at this moment, gear drive allows lid to rotate the angle corresponding to this gap the most extraly, make to cover 101 and main frame 102 be in 180 ° of flat of bottom surface alignment, but by described gap, the angle that first axle rotates is more more than the second axle, and the open angle of biaxial hinge has exceeded 180 °.Such as when needs the first axle is than the second many rotations of axle 6 °, then the above-mentioned gap of the one pair of which meshing gear of Spur Gear Driving mechanism 3-3 can be adjusted to the angle idle stroke of corresponding 6 °, but in general, as shown in Figure 3 a, this angle idle stroke of 6 ° can be shared in three pairs of meshing gears of Spur Gear Driving mechanism 3-3, the angle idle stroke that the above-mentioned gap of every pair of meshing gear is corresponding 2 °, or, both use accelerating gear drive mechanism, use again described gap.

Lid 101 and the Centered this 180 ° of flat of main frame 102 for Fig. 4 c, described gear drive can be used for when biaxial hinge is opened to the open angle of design by gear drive transmission, and the gap of its tooth being in the position of engagement is more than the gap when being engaged of other tooth about.

The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and change or the modification made all are contained among protection domain of the present utility model.
