Abstract

The utility model provides a mobile communication terminal sliding closure hinge, which comprises two sliding bodies which are respectively arranged on the upper portion and the lower portion, wherein a rack is arranged on one of the sliding bodies, a gear which is meshed with the rack and an energy storage mechanism are arranged on the other one sliding body, and the energy storage mechanism can push the gear to rotate when stored energy is released. The extreme distance of the sliding stroke of the mobile communication terminal sliding closure hinge just depends on the length of the rack in theory, thereby being capable of more easily achieving the sliding of large travel, being capable of easily achieving the upward circular sliding of a sliding closure, the sliding of a multiple-stroke sliding closure, the two-way sliding of the sliding closure and the lateral sliding of the sliding closure, and the mobile communication terminal sliding closure hinge creates sufficient hardware support for multi-function development of a sliding closure type mobile communication terminal.

Description

A kind of mobile communication terminal closure hinge of sliding

Technical field

The utility model relates to the mobile communication terminal closure hinge of sliding.

Background technology

At present,, adopt sliding lid construction very general such as mobile communication terminals such as mobile phone, Personal Handyphone Systems, the mobile communication terminal of sliding lid construction, its loam cake and lower cover are connected through the hinge.The semiautomatic cover-slid hinge is a hinge relatively more commonly used in the slip lid syndeton, it is provided with the driving mechanism of slip lid, driving mechanism often adopts driving spring as driving part, when the operator promotes slip lid, driving spring distortion such as is stretched, compresses or reverse and the savings energy, after the operator promotes slip lid and crosses critical point, promptly spring transfer to by the savings energy release energy after, slip lid can continue slip under the driving of spring.Present closure hinge of sliding exists sliding stroke to slide apart from little, multiple-pass and realizes difficulty and be difficult to the problem that the realization arc slides, and influences the multifunctional development of sliding closure type mobile communication terminal.

Summary of the invention

Technical problem to be solved in the utility model provides and a kind ofly can provide the mobile communication terminal closure hinge of sliding of hardware foundation for realizing the multiple sliding type of slip lid easily.For this reason, the utility model is by the following technical solutions: it comprises apportion two slide masses up and down, on a slide mass tooth bar is installed therein, be equipped with on another slide mass and described tooth bar meshed gears and stored energy mechanism, described stored energy mechanism can promote the gear rotation when energy storage discharges.Owing to adopt the technical solution of the utility model, sliding stroke critical distance of the present utility model only depends on the length of tooth bar in theory, can more easily realize the slip of big stroke, and, can realize slip lid make progress arc slip, the slip of multiple-pass slip lid, the two-way slip of slip lid, slip lid lateral sliding easily, for the multifunctional development of sliding closure type mobile communication terminal is created sufficient hardware supports.

Embodiment

With reference to accompanying drawing.The utility model comprises apportion two

slide masses

1,2 up and down,

slide mass

1,2 can be thin plate, tooth bar 3 is installed on slide mass 1, is equipped with on slide mass 2 and described tooth bar meshed gears 4 and stored energy mechanism, described stored energy mechanism can promote the gear rotation when energy storage discharges.

Described stored energy mechanism comprises fixed axis 51, outer container 52, the sliding part 53 that can slide along fixed axis, the rotating part 54 that can rotate around fixed axis, the spring 55 that acts on sliding part, and described gear combines with rotating part.Described fixed axis 51 pass rotating part 54, sliding part 53, spring 55 successively and outside the bottom surface of outer container 52 by jump ring 56 clampings.

Sliding part 53 is limited and can not rotate by relative fixed axle 51, and described spring 55 is between outer container and the described sliding part 53, and sliding part 53 and rotating part 54 are coaxial and establish.

Having cam surface 57 between sliding part and the rotating part, also is that cam surface can be arranged on sliding part on the surface of rotating part, and rotating part is provided with the member that contact is slided on cam surface; Or cam surface is arranged on rotating part on the surface of sliding part, and sliding part is provided with the member that contact is slided on its cam surface; Or sliding part is provided with cam surface respectively with the surface that rotating part is faced mutually, and two cam surfaces have contacted position.Described cam surface has the rising section and the decline section of linking.

Described gear and rotating part unitary construction and be combined as a whole, described gear also can combine by modes such as interference fit, the cooperations of keyway mating edge with rotating part and rotate.

Described tooth bar 3 is installed on a side of slide mass 1, and sliding panel 2 is provided with to step down at corresponding tooth bar place and covers groove 21, to dodge, to protect tooth bar.

Described tooth bar by the welding, heat is melted or the embedding and injection molding mode is installed on slide mass; Stored energy mechanism also can by the welding, heat is melted or mosaic mode is fixed on the slide mass 2.

Drawing reference numeral

61 and 62 is for being arranged on the slide rail of sliding panel 2 both sides.

When promoting one of them of

slide mass

1,2, sliding part 53 and rotating part 54 relatively rotate, at this moment, sliding part 53 is in the rising section of cam surface and one of them section in the decline section with contacting of rotating part 54, this section makes sliding part slide to the direction away from rotating part, make sliding part 53 to the motion of the bottom of outer container, spring 55 is compressed and energy storage.Behind the contact point of sliding part 53 and rotating part 54 breakover point through the rising section of cam surface and decline section, spring 55 releases energy, and sliding part is slided in the other direction from trend by spring action, make slip lid after motion in open automatically.

When described tooth bar is made its surface along the tooth bar length direction when curved, when gear rolls at rack surface, slide

mass

1 and 2 one of them do movement in a curve, can realize the arc sliding opening of slip lid mobile device easily.

The rising section of cam surface and each loop cycle of decline section can both make hinge be in metastable state, thereby can not rely on the casing location, and realize the multiple-pass slip of slip lid mobile device, two-way slip easily.

By adjusting the installation direction of tooth bar, gear, stored energy mechanism easily,, can realize easily that the slip lid forward slides and lateral sliding such as selecting length direction or Width that hinge is set along mobile device.
