Abstract
The utility model provides a drive device in the slide cover hinge of a mobile communication terminal. The drive device comprises a pair of L-shaped ejector pins; the L-shaped ejector pin comprises a straight arm part, a slide groove arranged on the hook end, a tension spring connecting position between the straight arm and the slide groove and the connecting position of the slide board arranged in the slide cover hinge on the top end of the straight arm; the straight arms of the two ejector pins are in parallel; wherein, one straight arm of the straight arms can in slide insertion with the slide groove of the other ejector pin; the tension spring is connected with the two tension spring connecting positions on the two ejector pins; an angle is formed between the connecting line on the top ends of the ejector pins of the drive device and the tension spring; when the ejector pin pushes the slide cover to move beyond the critical point; the angle formed between the connecting line on the top ends of the ejectors and the tension spring can weaken the sense of pause so that the slide cover is ensured to slide more smooth; the sense of comfortable using for the user is improved.
Description
Technical field
The utility model relates to the drive unit in 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.But present sliding lid construction has pause sense clearly when the operator promotes the slip lid postcritical, influence user's use comfort.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of drive unit that makes in the more smooth mobile communication terminal closure hinge of sliding of slip lid slip.For this reason, the utility model by the following technical solutions: it comprises extension spring and a pair of
The shape push rod, described
The shape push rod comprises straight-arm part, be in the chute of hook end, be in the connection position that extension spring between straight-arm and the chute connects the position, is in sliding panel in the closure hinge of sliding on straight-arm top, the straight-arm of described two push rods is parallel to each other, the straight-arm of one of them inserts chute in another push rod slidably, and extension spring is connected in two extension springs on the push rod and connects the position.Owing to adopt the technical solution of the utility model, has angle between the line on the utility model two push rod tops and the extension spring, when critical point is crossed in the motion of push rod promotion slip lid, existing angle can weaken the sense that pauses between the line on push rod top and the extension spring, it is more smooth that slip lid is slided, and improves user's use comfort.
Description of drawings
Fig. 1 is the schematic diagram of a kind of execution mode of the utility model.
Fig. 2 is the explosive view of Fig. 1.
Fig. 3 is the aspect graph 1 of two push rod relative positions embodiment illustrated in fig. 1.
Fig. 4 is the aspect graph 2 of two push rod relative positions embodiment illustrated in fig. 1.
Fig. 5 is the aspect graph 3 of two push rod relative positions embodiment illustrated in fig. 1.
Embodiment
With reference to accompanying drawing.Drive unit in the mobile communication terminal closure hinge of sliding provided by the utility model, it comprises extension spring 3 and a pair of
Shape push rod 10 and 20, described
Shape push rod 10 and 20 comprises straight-arm part 11 and 21 respectively, be in the chute 12 and 22 of hook end, be in extension spring between straight-arm and the chute connect position 13 and 23, be in sliding panel in the closure hinge of sliding on straight-arm top be connected position 14 and 24, the straight-arm 11 and 21 of described two push rods is parallel to each other, the straight-arm of one of them inserts chute in another push rod slidably, promptly, straight-arm 11 is inserted in the chute 22, straight-arm 21 is inserted in the chute 12, and extension spring is connected in two extension springs on the push rod and connects the position.Wherein, extension spring and straight-arm 11 and 21 be arranged in parallel, and structure is the most reasonable.
When Fig. 3 closes for slip lid is in, the aspect graph of two push rod relative positions, Fig. 4 drives the aspect graph of two push rod relative positions after the slip that slip lid carries out a stroke for drive unit, and Fig. 5 carries out the aspect graph of two push rod relative positions after the slip of another stroke for drive unit driving slip lid.In the driving process, has angle between the line on two push rod tops and the extension spring all the time, when the operator promotes slip lid and crosses critical point, being extension spring is transferred to when releasing energy by the savings energy, can weaken the sense that pauses of sliding, it is more smooth that slip lid is slided, and improves user's use comfort.
Present embodiment and accompanying drawing thereof have only shown described in the utility model
A kind of concrete shape of shape push rod, any change to the push rod shape as long as have angle between the line on two push rod tops and the extension spring, still belongs to the push rod that is equal to mutually.
Claims (1)
1. the drive unit in the mobile communication terminal closure hinge of sliding, it is characterized in that it comprises extension spring and a pair of J-shaped push rod, described J-shaped push rod comprises straight-arm part, be in the chute of hook end, be in the connection position that extension spring between straight-arm and the chute connects the position, is in sliding panel in the closure hinge of sliding on straight-arm top, the straight-arm of described two push rods is parallel to each other, the straight-arm of one of them inserts chute in another push rod slidably, and extension spring is connected in two extension springs on the push rod and connects the position.
