Abstract

The utility model relates to cover-lifting pivot structure of an electronic device; which utilizes the adjacent sides of the upper and lower cover, uses a pivot and a pivot hole to hinge the two covers together to form a electronic device (such as individual digital assistant, mobile phone, laptop or panel PC, electronic calculator... etc). The margin wall of the pivot has a plurality of positioning bump, these positioning bumps are in correspondent to the positioning slots on the pivot hole wall. When the pivot turns, the whole pivot will distract outwards along the axis because of the interference between three bumps and the middle frame body (because the plastic material is elastic); and the pivot will recovers when turns to 120 degree; so that to increase the structure strength after connection, avoid the positioning difficulty phenomenon caused by over-wear. Moreover when the upper or lower cover is lifted, a positioning sense of ratchet wheel effect is reached; and the convenience of use is enhanced.

Description

The flip pivot structure of electronic installation

Technical field

The utility model relates to a kind of flip pivot structure of electronic installation, especially refer to that a kind of electronic installation of cover-lifting type that can effectively help is (as personal digital assistant, mobile phone, notebook computer or flat computer, electronic calculator ... Deng) the location, simultaneously, strengthen the utility model creation of pivot structure intensity.

Prior art

In the prior art, the electronic installation of general cover-lifting type is (as personal digital assistant, mobile phone, notebook computer or flat computer, electronic calculator ... Deng), as shown in Figure 2: it is in the adjacent side of loam cake 1, lower cover 2, both articulate with it to utilize close-fitting rotating shaft 3, so that its loam cake 1, lower cover 2 can reach the purpose that starts or cover.

The pivot joint mode of above-mentioned existing electronic installation has following shortcoming in the use at least:

(1) this rotating shaft 3 is effects of utilizing friction tight effect that this loam cake 1 is reached to start the location, back, therefore, as easy as rolling off a logly when excessively using makes friction tight these rotating shaft 3 abrasion, and then loses its locating effect.

For exempt from this upper and lower cover 1,2 turn-on overshoots take place, this rotating shaft 3 in be formed with a location salient point 31, to reach the effect that stop (2) again,, but, because this single positioning convex point 31 is because of being subject to the volume problem, therefore, its structural strength is also inadequate, so, the situation of as easy as rolling off a log generation fracture.

As from the foregoing, the electronic installation of above-mentioned existing cover-lifting type in the use of reality, obviously has inconvenience and exists with shortcoming, and remain to be improved.

The utility model content

In order to solve the above-mentioned shortcoming that exists in the prior art, main purpose of the present utility model provides a kind of flip pivot structure of electronic installation, the electronic installation that is particularly useful for cover-lifting type is (as personal digital assistant, mobile phone, notebook computer or flat computer, electronic calculator ... Deng) rotating shaft on, and when this rotating shaft is rotated, can make whole rotating shaft strut (because of the material of plastics own has elasticity) outward because of the interference of three salient points and center main body with axis direction, waiting to rotate 120 degree backs recovers, so as to its location of effective help, simultaneously, strengthen its intensity, and help the user in use, because its loam cake and lower cover remain under the state with angle of inclination, operation is convenient.

Another purpose of the present utility model provides a kind of flip rotating shaft project organization of electronic installation, and these a plurality of enhancing structures can effectively be strengthened whole location sense when stopping effect and flip, so as to making things convenient for the user.

In order to achieve the above object, the utility model provides a kind of flip pivot structure of electronic installation, it is to utilize on one, the side that lower cover is adjacent, use a rotating shaft and a corresponding pivot hole to articulate and form 1 electronic installation (as personal digital assistant, mobile phone, notebook computer or flat computer, electronic calculator ... Deng), wherein, be formed with three positioning convex points that are provided with at interval on the edge wall of this rotating shaft, and each positioning convex point is to correspond respectively to formed location notch on the pivot peritreme wall, when rotating shaft is rotated, can make whole rotating shaft strut (because of the material of plastics own has elasticity) outward because of the interference of three salient points and center main body with axis direction, waiting to rotate 120 degree backs recovers, can form the ratchet relation simultaneously, and after it is linked.

Embodiment

In order further to understand invention main points of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet institute's accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

For reaching above-mentioned purpose of the present utility model, a preferred embodiment cited below particularly, and in conjunction with the accompanying drawings, be described in detail below:

See also Fig. 2 and shown in Figure 3, the utility model provides a kind of flip pivot structure of electronic installation, refers to a kind of novel creator that can effectively help the electronic installation location of cover-lifting type and increase structural strength especially; It is to utilize on one, the side that

lower cover

21,22 is adjacent, use a rotating shaft 23 and a corresponding pivot hole 24 to articulate and form an electronic installation 20, this electronic installation 20 is to be personal digital assistant, mobile phone, notebook computer or flat computer, electronic calculator ... Deng article; Because above-mentioned structure is same as the prior art, is not the category of the utility model patent protection, so relevant its structure and connected mode etc. are promptly no longer given unnecessary details at this.

Please continue and consult Fig. 2, Fig. 2 A, Fig. 2 B, Fig. 3 and shown in Figure 4, in the utility model, be formed with three positioning convex points 231 that are provided with at interval on the edge wall of this rotating shaft 23 (shown in Fig. 2 A and Fig. 2 B), respectively this positioning convex point 231 corresponds respectively to formed location notch 241 on the 24 edge walls of pivot hole, so, when this rotating shaft 23 is rotated, can interfere with the center main body because of three positioning convex points 231 makes whole rotating shaft 23 strut (because of the material of plastics own has elasticity) outward with axis direction, waiting to rotate 120 degree backs recovers, simultaneously, also can make it form the ratchet relation, locating effect when starting so as to increasing this loam cake 21 simultaneously, prevents the situation that ruptures because of undercapacity, can effectively strengthen whole stereovision when stopping effect and flip, as shown in Figure 4.

Have the angle of inclination state because loam cake 21 and lower cover 22 after unlatching, can remain on, as shown in Figure 3, so help the user operation, watch etc., with increase user convenience in the use.

As mentioned above, according to " the flip pivot structure of electronic installation " of the present utility model, have following many advantages at least:

(1) avoid rotating shaft excessively to wear away.

(2) strengthen pivot structure intensity.

(3) increase the whole effect that stops.

(4) location that forms ratchet effect is felt.

(5) increase user's convenience in the use.

In sum; it only is preferable possible embodiments of the present utility model; be not so limit scope of patent protection of the present utility model; so; the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes; or directly or indirectly apply to other relevant technical field, all be contained in the protection range that the utility model contains.
