Abstract

The invention provides a buckle which is used for inserting a slot, the buckle is provided with a guiding surface so that the buckle can be easily released from the slot. The invention further provides an electronic device using the buckle. The electronic device comprises a body and a cover body; the slot is formed on the body and the buckle is arranged on the cover body; the buckle is blocked in the slot so that the cover body can be assembled on the body, and the guide surface is arranged on the buckle adjacent to one end of the cover body which is firstly opened, so that the buckle can be released from the slot. Compared with the prior art, in the process of removing the body, the cover body is regularly released from the body by the guiding of the guide surface, and in the process that the cover body is removed opposite to the body, as the buckle slides along the body in a smooth translation manner, an operator can extract the cover body from the body without applying large external forces.

Description

Buckle and use the electronic installation of this buckle

Technical field

The invention relates to a kind of buckle, especially about a kind of buckle that is applied on the electronic installation.

Background technology

Being equipped with on the portable electron device needs the often lid of unlatching, and as battery cover, the buckle of battery cover and electronic device body generally adopts buckle and draw-in groove buckle.More common at the sidewall and the two ends of battery cover buckle to be set, the buckle of the corresponding battery cover in the body sidewall of electronic installation and two ends is provided with draw-in groove.When battery cover is installed, at first the end with battery cover is sticked on the body, promote battery cover then and make its end slide to body obliquely, and the buckle of battery cover both sides is snapped in the draw-in groove of sidewall of housing, thereby battery cover is installed on the body around above-mentioned battery cover.Right in case above-mentioned buckle is with after draw-in groove engage, then need apply one greatly external force just can make its engagement release, so existing buckle is not easy to unlatching.

Summary of the invention

In view of foregoing, be necessary to provide a kind of buckle of being convenient to open.

In addition, also be necessary to provide a kind of electronic installation of using above-mentioned buckle.

A kind of buckle, this buckle is in order to snap in the draw-in groove, and this buckle is provided with a guide surface, so that buckle breaks away from this draw-in groove.

A kind of electronic installation, comprise a body and a lid, this body and this lid are respectively equipped with a draw-in groove and a buckle, this buckle is stuck in this draw-in groove releasedly so that this lid is assemblied on this body, this is snapped in an end of opening earlier towards this lid and is provided with a guide surface, so that guide this buckle to break away from this draw-in groove.

Compared to prior art, in the process that the relative body of lid of electronic installation of the present invention takes off, lid breaks away from body gradually under the guiding of its guide surface.Break away from the process of body at above-mentioned lid,, just lid can be scratched down from body with seamlessly transitting so the operator need not to apply too big external force because buckle is to slide along body.

Embodiment

Buckle of the present invention is applicable to electronic installation, and (personaldigital assistant PDA) and palmtop PC etc., is that example is illustrated with the mobile phone in the present embodiment as mobile phone, personal digital assistant.

See also Fig. 1, mobile phone 100 comprises that a body 10 and is covered on the lid 20 on this body 10.Body 10 roughly is a framework, and it comprises two relative frame walls 12.Wherein the outside of the contiguous one of a frame wall 12 ends offers a draw-in groove 14, and another frame wall 12 this draw-in groove 14 dorsad also offers another draw-in groove 14, and is equipped with a snap-latch surface 142 in order to engage with lid 20 in described two draw-in grooves 14.The other end of body 10 is provided with some portions that are clasped (figure does not show).The described draw-in groove 14 and the portion of being clasped are all in order to cooperate in order to lid 20 is assembled on the body 10 with lid 20.

See also Fig. 2 and Fig. 3, lid 20 comprises two relative sidewall 22 and the opening ends 23 in order to elder generation's this lid 20 of unlatching.Convex with a buckle 24 towards another sidewall 22 on each sidewall 22, described buckle 24 is oppositely arranged and is sticked in liftedly in the described draw-in groove 14.It is leg-of-mutton cylinder that described buckle 24 roughly is a cross section, and each buckle 24 comprises a buckle face 242, a surface 244 and one end face 246.The end face 246 of described buckle 24 is provided with towards the opening end 23 of this lid 20, is formed with a guide surface 248 on this end face 246, and described guide surface 248 intersects setting with buckle face 242 and surface 244.Described buckle face 242 is in order to support with the snap-latch surface 142 of body 10 and to engage.Described guide surface 248 slides so that buckle 24 breaks away from the draw-in groove 14 of body 10 along snap-latch surface 142 in order to guide this buckle face 242.Also be provided with some clamping parts suitable with the portion that is clasped quantity body 10 (figure does not show) on this lid 20, described clamping part engages with the described portion of being clasped.This guide surface 248 is a lozenges in the present embodiment.

See also Fig. 4 and Fig. 5, assembling is during mobile phone 100, provides an external force to push the buckle 24 of lid 20 draw-in groove 14 of body 10 to, make two buckles 24 mutually away from and strain to gather elastic force.When the draw-in groove 14 of buckle 24 adjacent body 10, above-mentioned elastic force obtains gradually discharging and drives buckle 24 and slips in the draw-in groove 14, support until the buckle face 242 of buckle 24 snap-latch surface 142 with body 10, and this moment buckle 24 buckle face 242 and the stack area between the snap-latch surface 142 of body 10 increase gradually along guide surface 248 by end face 246.Just the clamping part of lid 20 snaps in the portion that is clasped of body 10 then, and mobile phone 100 is just assembled and finished.

See also Fig. 2 and Fig. 6, when body 10 took off lid 20, at first just the opening end 23 of lid 20 was scratched from body 10 and is opened, and makes opening end 23 relative body 10 perks of lid 20, simultaneously, buckle 24 is provided with draw-in groove 14 perks of the relative body 10 of an end of end face 246.Be provided with in the process of an end perk of end face 246 at buckle 24, the buckle face 242 of buckle 24 slides along the snap-latch surface 142 of body 10, buckle 24 deformation simultaneously and the snap-latch surface 142 that drives its guide surface 248 and body 10 support, and buckle 24 end that is provided with end face 246 breaks away from draw-in groove 14 gradually under the guiding of guide surface 248 then.The other end until buckle 24 breaks away from draw-in groove 14, and lid 20 is just taken off from body 10.

It is leg-of-mutton column that the shape that is appreciated that buckle 24 is not limited to cross section, also can be other shape, is tetragonal column as cross section.The shape of cross section that is not provided with guide surface 248 places when buckle 24 is a parallelogram or when trapezoidal, the buckle face 242 of buckle 24 is parallel to each other with surface 244.

Be appreciated that, guide surface 248 be in order to guide this buckle face 242 to slide so that buckle 24 breaks away from the draw-in groove 14 of bodies 10 along snap-latch surface 142, so guide surface 248 is not limited to lozenges, also can be for other structure, as curved surface as long as reach the above-mentioned functions guide surface 248 of guide surface 248.

In the process that the lid 20 relative bodies 10 of mobile phone 100 of the present invention take off, lid 20 breaks away from body 10 gradually under the guiding of its guide surface 248.Break away from the process of body 10 at above-mentioned lid 20,, just lid 20 can be scratched down from body 10 with seamlessly transitting so the operator need not to apply too big external force because buckle 24 is to slide along body 10.
