Below in conjunction with accompanying drawing the present invention being done one specifically introduces.

See also Fig. 1, be depicted as the STRUCTURE DECOMPOSITION figure of a kind of cover mechanism 100 that better embodiment of the present invention provides.Described cover mechanism 100 comprises that a lid 10, is arranged at the mechanism 20 of upspringing of described lid 10 belows, and a locating support 21 that is connected with the described mechanism 20 of upspringing.The described mechanism of upspringing comprise one rotating be arranged on the described locating support 21 and with the torsion member 22 of described lid 10 butts, an and return unit 23 that is arranged on the described locating support 21 and flexibly supports with described torsion member 22.

Described locating support 21 comprise a base plate 211 and with described base plate 211 one first side plate 212 connected vertically and one second side plates 213.Offer one first pivot hole 2121 and one second pivot hole 2122 on described first side plate 212.The position in the contiguous described second pivot hole 2122 offers a chute 2123 and a location hole 2124, and described return unit 23 is arranged in described chute 2123 and the described location hole 2124.

Described torsion member 22 comprises a swing arm 221 and one and described swing arm 221 integrated trailing arms 222, described swing arm 221 tops are formed with a torque shaft 2211, described torque shaft 2211 rotating being arranged in the described first pivot hole 2121, described trailing arm 222 connects with described lid 10 lower surfaces.

In the present embodiment, described torque shaft 2211 be one with described swing arm 221 integrated hollow cylinders, certainly this torque shaft 2211 also can be the solid cylinder that is formed at these swing arm 221 tops, perhaps, offer a through hole corresponding to the described first pivot hole 2121 in the position of this torque shaft 2211, link to each other by a pivot between this through hole and the described first pivot hole 2121.

Described trailing arm 222 comprises that a driver plate 2221 and is positioned at described driver plate 2221 tops and described driver plate 2221 supporting plates 2222 connected vertically, the lower surface of the described lid 10 of described supporting plate 2222 supports.Described driver plate 2221 connects a side of described swing arm 221, and described driver plate 2221 is an arc, and its two ends connect described supporting plate 2222 and described swing arm 221 respectively.

Also fixedly be equipped with two holder posts 2223 on the described supporting plate 2222, be used for the described lid 10 of butt.The quantity of described holder post 2223 is not limited to two, and it also can be one-body molded with described supporting plate 2222.

Described return unit 23 comprises that one is arranged in reference columns 231 and in the described second pivot hole 2122 and is sheathed on torsion spring 232 on the described reference column 231, described torsion spring 232 comprises a helical form reverse part 2321 and from extended two elastic foots 2322 in 2321 two ends, described reverse part, described elastic foot 2322 respectively comprises a kink 2323, the kink 2323 of one of them elastic foot 2322 inserts in the described location hole 2124, and the kink 2323 of another elastic foot 2322 inserts in the described chute 2123.Kink 2323 elasticity that are positioned at described chute 2123 are connected to a side of the swing arm 221 of described torsion member 22.

Described reference column 231 parts pass the described second pivot hole 2122 and connect to limit the rotating distance of described swing arm 221 with the swing arm 221 of described torsion member 22, avoid swing arm 221 to rotate described torsion spring 232 is caused damage.

Be appreciated that described reference column 231 can omit, and two side projections arranged in that 2122 positions, the second pivot hole of described first side plate 212 and described first side plate 212 are one-body molded.

Certainly, torsion member described in the present embodiment 22 and return unit 23 are arranged on first side plate 212 of described locating support 21, certainly, similarly torsion member and return unit also can be arranged on second side plate 213 of described locating support 21, on perhaps described first, second side plate 212,213 torsion member and return unit are set all.

See also Fig. 2, schematic diagram after the assembling that is depicted as cover mechanism 100 of the present invention is finished, wherein said lid 20 is connected on the product shell (figure does not show) near a side of described locating support 21 is rotating, and described locating support 21 is arranged in the described product shell.Described torsion member 22 is articulated in the first pivot hole 2121 of described first side plate 212, and a side of described swing arm 221 is connected to the elastic foot 2322 that described torsion spring 232 is positioned at described chute 2123, and described supporting plate 2222 is connected to the lower surface of described lid 10.Described torsion spring 232 is the compressive state setting.Originally be illustrated as the state of cover mechanism 100 when described lid 10 is closed, the described torsion spring 232 of described swing arm 221 compressions is to the end of described chute 2123 near described location holes 2124.

See also Fig. 3, when described lid 10 is in opening, the elastic foot 2322 that described torsion spring 232 is positioned at described chute 2123 at the described chute 2123 in effect lower edge of torsion spring 232 self elastic force to a lateral movement away from described location hole 2124.Thereby driving described swing arm 221 is the center with its torque shaft 2211, along the direction of motion swing identical with described elastic foot 2322, and then the supporting plate 2222 that drives described trailing arm 222 moves upward to hold up described lid 10, makes described lid 10 away from motion one segment distance on the side direction of described locating support 21.

The mechanism of upspringing of described cover mechanism can directly be positioned on the locating support, need not to be its special syndeton and installation structure of design in addition, and therefore described cover mechanism structure is more simple, and assembling easily and to assemble shared space also smaller.

In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
