Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model flip-shell electronic dictionary comprises: upper shell 1, lower house 2 and be connected between the two wheelwork 3 be connected panel 4.Described upper shell 1 comprises upper shell panel 11, upper shell panel 12 (figure does not show), embeds the display screen 10 of panel, is arranged at the control circuit board in the space that is formed by the upper and lower panel fastening; Described lower house 2 comprises lower house panel 21, lower house panel 22 (figure does not show), place lower house panel 21, lower house panel 22 plates to fasten and control circuit board in the space that forms, be embedded at the keyboard 20 of lower house panel.Described wheelwork 3 is by connecting panel 4 secure closure parcel.
Special feature of the present utility model is: upper shell 1, lower house 2 can be realized the stable needed angle of user that stays in of both multi-angles after both connect by wheelwork 3.Described wheelwork 3 is provided with damping unit 5, describes in detail respectively below.
As shown in Figures 2 and 3, described wheelwork 3 comprises: first rotating shaft 31, second rotating shaft 32, two range line bearing plates 310, four bayonet socket pads 311, four springs 312, two damped parts 313, two first gears 314, two second gears 324, two connect pad 315, first and connect support 316 and be connected support 326 with second.Wherein, the both ends of described first rotating shaft 31 and second rotating shaft 32 are provided with first axially grooved 3101 and second axially grooved 3201 respectively.Two connect pad 315 and are inserted in from first rotating shaft 31, second rotating shaft, 32 two ends and make first rotating shaft 31, second rotating shaft 32 mutually concordant to the axle rank of diameter of axle maximum.First gear 314 is with after second gear 324 meshes into gear mesh, band double wedge toothed disc faces outer be inserted in respectively described first rotating shaft 31 and second rotating shaft 32, first gear 314 or second gear, 324 shaft part radial sections of living in are for the circular pincushion face of circular arc up and down of pruning, and are consistent with the radial section shape of first gear 314 or second gear, 324 through holes.Described first rotating shaft 31 and first gear 314, second rotating shaft 32 and second gear 324 form circumferentially firm pillow shaped hole shaft coupling, make relative static, second rotating shaft 32 with first gear 314 of first rotating shaft 31 and second gear 324 static relatively.Then the rotation of first rotating shaft 31, second rotating shaft 32 can only realize by the engagement rolling between described first gear 314 and second gear 324.
After damped part 313 with two through holes is inserted in described first rotating shaft 31 and second rotating shaft 32, allow the double wedge 3141 of its groove 3131 described first gears 314 of engagement or second gear, 324 gear cards.Described spring 312 is inserted in from first rotating shaft 31, second rotating shaft, 32 two ends respectively, compresses damped part 313; Range line bearing plate 310 follows spring 312 closely and is inserted in and is fixed in and connect panel 41, at last bayonet socket pad 311 is blocked in the ring groove that is inserted into first rotating shaft 31,32 liang of ends of second rotating shaft from the side, thereby limits the axial displacement of described spring 312.Described range line bearing plate 310 is one of the forming has three through holes
The shape structure, in the both sides up and down of its " Shu " portion one through hole that rotating shaft is passed through is set respectively, left distal end in its " one " portion is provided with a through hole, make its can with connect going up of panel 4 connect panel 41 and time be connected the through hole of panel 42 relevant positions corresponding, thereby reach first rotating shaft 31, second rotating shaft 32 and be connected the effect that panel 4 fixes.The groove 3131 that described damped part 313 1 sides are provided with as shown in Figure 5, the side of described first gear 314 and second gear 324 is provided with the double wedge 3141 that a plurality of and described groove 3131 cooperates, as shown in Figure 6.Double wedge 3141 with upper spring 312, damped part 313, first gear 314 and second gear, 324 sides constitutes described damping unit 5: because the double wedge 3141 of described first gear 314 and second gear, 324 cards is engaged in the groove 3131 of damped part 313, limited the relative rolling of described first gear 314 and second gear 324.When the torsion that puts on first gear 314 and second gear 324 giving full measure when overcoming the pressure of spring 312 in the axial direction, spring 312 compression deformations, damped part 313 is after the axial displacement of two ends, described double wedge 3141 breaks away from the groove 3131 of damped part, the relative rolling restriction of described first gear 314 and second gear 324 is disengaged, before double wedge 3141 was engaged in the groove 3131 of damped part 313 next time, the level and smooth rotation appearred in described first rotating shaft 31 and second rotating shaft 32.Behind first gear 314 and second gear, 324 rolling certain angles, under the pressure of spring 312, the groove 3131 of described damped part 313 once more with double wedge 3141 engagement of described first gear 314 or second gear 324, thereby lock the rotational angle of described first rotating shaft 31 and second rotating shaft 32.The rotary damping of described first rotating shaft 31 and second rotating shaft 32 makes described double wedge 3141 present engagement with groove 3131---the effect that non-engagement alternately occurs.Because the whole rotation process of two rotating shafts rotates by two gear meshing and realizes, the minimum angles of rotating should depend on the distribution density of the tooth on the gear, and damping intensity then depends on described double wedge 3141 and the facing type of groove 3131 and the deformation coefficient of spring 312.
As shown in Figure 4, the jut that the U type first of band through hole connects support 316 two ends place respectively described first rotating shaft 31 axially grooved 3101 and fastening, the jut that the U type second of band through hole connects support 326 two ends place respectively second rotating shaft 32 axially grooved 3201 and fastening, fastening means can be selected welding manner.Described first connects support 316 is fixed to upper shell 1 by body through-holes with screw, and described second connects support 326 is fixed to lower house 2 by body through-holes with screw; With connect down panel 42 cover wheelworks lower surface and with on be connected the panel 41 fastening formation that coincide and change complete connection panel 4.The height and the last lower house that connect panel 4 are consistent, and make under 180 ° of open modes of lower house described upper shell 1, lower house 2 and to be connected panel 4 threes concordant, one integrated mass.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model.As damping unit 5, its groove 3131 and double wedge 3141 structures can mutual alternative; Spring 312 optional usefulness have the elastomeric material spare of certain distortion elastic force; Range line bearing plate 310 can adopt to insert and connect vertical rib groove realization restraining spring 312 axial displacements in panel 4 cavitys; The circumferentially firm coupling of described first rotating shaft 31 and first gear 314 or second rotating shaft 32 and second gear 324 can adopt interference coupling or keyway arrangements etc.
To one skilled in the art, the utility model can have various changes and variation, and is all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
