Abstract

The utility model discloses a semi-automatic swing device, which comprises a pivoting piece, a relative pivoting piece, and a plurality of bar-shaped twisting elastic components, wherein, the pivoting piece is pivoted with the relative pivoting piece through a pivot, and the bar-shaped twisting elastic components are arranged at the periphery of the pivot; two ends of each of the twisting elastic components are respectively connected with the relative pivoting piece and the pivoting piece, so as to allow the twisting elastic components to be obliquely arranged between the relative pivoting piece and the pivoting piece beside the pivot; through the relative pivoting of the pivoting piece and the relative pivoting piece, two ends of each of the twisting elastic components gradually move to a positive corresponding position from a deflective position, thereby compressing the twisting elastic components for storing energy at the same time; and when the two ends of each of the twisting elastic components pass through the positive corresponding position, the twisting elastic components can gradually expand from a compressed state, realizing the automatic pivoting of the pivoting piece and the relative pivoting piece.

Description

Semi-automatic commentaries on classics pendulum device

Technical field

Originally relate to a kind of semi-automatic commentaries on classics pendulum device.

Background technique

Along with various electronic products with flip or screen are constantly gone on the market by exploitation; The pivot that is widely used is turned round device also has many different aspects and structure thereupon; Turn round device like Fig. 1, a common pivot shown in Figure 2, its structure mainly comprises: first and second cam 5 that pin joint seat 4, axle 40, two are identical, 5a, two identical

fixed plate

6,6a and elastic components 60 etc.; Wherein pin joint seat 4 has a vertically extending side plate 41, is provided with a pivot hole 42 in side plate 41 central authorities, and 42 sides are provided with the stopper part 45 of a convexity in the pivot hole; Axle 40 stage casings are provided with a lip part 401; Be provided with the restriction shaft part 402 on a tool plane 403 in axle 40 1 ends, restriction shaft part 402 can pass the pivot hole 42 of side plate 41, with lip part 401 blocks in side plate 41; Be provided with between lip part 401 and the side plate 41 one with the stop block 46 of axle 40 pivot in unison; Stop block 46 all sides are provided with two relative 461,462, two blocked parts, blocked part, 461,462 ability blocks form a pivoting angle in the stopper part 45 of side plate 41 restriction, and first and

second cam

5,5a can be sleeved on the restriction shaft part 402 pivotally; First cam 5 is with fixing part (as: two fixed holes 43 of two fixing pins, 51 build-ins, two correspondences on side plate 41; Or two fixed grooves 44, or a fixed hole 43 and a fixed groove 44), the second cam 5a is with two fixing pin 51a build-ins, two corresponding fixing parts (as: two fixed grooves 61) on fixed plate 6; Opposite side in first and

second cam

5,5a has a rubbing surface respectively, on rubbing surface, is respectively equipped with

protuberance

51,54a and

recess

53,53a;

Fixed plate

6,6a can be arranged on the restriction shaft part 402 synchronously linkedly; Between

fixed plate

6,6a, be provided with an elastic component 60; Elastic component 60 can be made up of a plurality of 601 of arc spring laminations with restriction shaft part 402 synchronous interlocks, is provided with a packing assembly 404 in the end that limits shaft part 402 and pushes against in fixed plate 6a.

Said structure is when practical application, and when first and second cam 5, when 5a is in initial position, protuberance 54 correspondences of first cam 5 embed the recess 53a of the second cam 5a, and the corresponding recess 53 that embeds first cam 5 of the protuberance 54a of the second cam 5a is used to form and located.

When axle 40 is rotated with respect to pin joint seat 4; Its restriction shaft part 402 drives fixed plate 6 and rotates, and makes the second cam 5a rotate synchronously with axle 40, and then the protuberance 54 of first cam 5 shifts out the recess 53 of the second cam 5a; First cam, 5 volume protuberances 54 contact with the rubbing surface of the second cam 5a; The protuberance 54a of the second cam 5a shifts out the recess 53 of first cam 5 simultaneously, makes the protuberance 54a of the second cam 5a contact with the rubbing surface of first cam 5, produces the variation of torsion; When pin joint seat 4 and axle 40 resetted,

protuberance

54,54a can move closer to

recess

53a, 53, corresponding once more automatic chimeric answer.

Though this kind structure can provide the location of axle 40 in special angle; The frictional force required with general fixed angle, it is comparatively limited by 601 elasticity that can produce of a plurality of arc spring laminations, is difficult to produce bigger frictional force; Thereby can't satisfy the required big frictional force in more large-scale electronic product pivot location; Simultaneously, this kind forms structure and assembling mode is comparatively complicated, is difficult for changing this elastic component 60; Therefore it is essentially fixing for 40 frictional force that can produce of axle and can't adjusts, and this all possibly cause the disappearance in the application.
