Embodiment
Please refer to Fig. 4 and Fig. 5, Fig. 4 is that schematic diagram, Fig. 5 that the present invention discloses the portable apparatus 2 with multiple fastening structure housing 200 is the decomposing schematic representation of portable apparatus 2.Wherein portable apparatus 2 separately comprises an electronic installation 300, is placed in housing 200.The housing 200 of portable apparatus 2 comprises a cap 40, a middle frame structure 50 and a body 60, wherein middle frame structure 50 has one first snap fit 51 and one second snap fit 52, the design and body 60 combinations that utilize double card to hook, with the bond strength of reinforcement middle frame structure 50 with body 60, the convenience when taking into account simultaneously part manufacturing, the demoulding and assembling.40 of caps are incorporated on middle frame structure 50 by the mode of its inboard recess 41 with salient point 55 (please refer to Fig. 8 and Fig. 9) engaging of middle frame structure 50 corresponding both sides; to cover and to protect the connector 301 of the electronic installation 300 in housing 200; and can disassemble on middle frame structure 50, wherein portable apparatus 2 can be as electronic installations such as portable hard drive, MP3 walkmans.
Please refer to Fig. 6 and Fig. 7, Fig. 6 is middle frame structure 50 schematic diagram of the housing 200 of portable apparatus, and Fig. 7 is body 60 schematic diagram of housing 200.Middle frame structure 50 on the figure the I direction and body 60 in conjunction with to be installed on body 60, middle frame structure 50 has one first snap fit 51 and one second snap fit 52, and the first snap fit 51 and the second snap fit 52 are positioned on same plane and along installation direction I and sequentially arrange.In other words, in Fig. 6, the first snap fit 51 is positioned at the left side of the second snap fit 52 on azimuth axis I.The first snap fit 51 has the first cantilever 514, the second snap fits 52 and has and have opening 54, the first snap fits 51 in the second cantilever 524, the second cantilevers 524 and extend opening 54 places.In the present embodiment, present U-shaped groove between the first snap fit 51 and the second snap fit 52, by two snap fits 51, the groove of 52, make the first cantilever 514 and the second cantilever 524 independently actuating to each other, therefore the first snap fit 51 and the second snap fit 52 independent cantilever by separately can be driven respectively distortion, and independently cantilever design one of can be therein snap fit when unclamping, another snap fit still with corresponding draw-in groove engaging, avoid middle frame structure 50 and body 60 to be opened.The opposite position that interosculates on the body 60 of installing with middle frame structure 50 has one first draw-in groove 61 and one second draw-in groove 62, and similarly, the first draw-in groove 61 and the second draw-in groove 62 are positioned on same plane and along installation direction I sequentially to be arranged.In other words, in Fig. 7, the first draw-in groove 61 is positioned at the left side of the second draw-in groove 62 on azimuth axis I.When middle frame structure 50 is installed on body 60 along installation direction I, the first snap fit 51 can be sticked in the first draw-in groove 61, the second snap fit 52 is sticked in the second draw-in groove 62, utilizes the design of two snap fits on same azimuth axis I, the weakness of the single snap fit installation strength of Strengthenable deficiency.
The transverse width of the first snap fit 51 and the first draw-in groove 61 is w
1, and the transverse width of the second snap fit 52 and the second draw-in groove 62 is w
2, and in the embodiment of Fig. 6 and Fig. 7, width w
2Greater than width w
1, therefore to work as middle frame structure 50 and be installed on along installation direction I in the process of body 60, the second snap fit 52 can be first by the first draw-in groove 61, due to the width w of the second snap fit 52
2Width w greater than the first draw-in groove 61
1, therefore can avoid the second snap fit 52 first to fall into the first draw-in groove 61 and cause assembly defect.Yet the snap fit of Fig. 6, Fig. 7 and draw-in groove are a wherein aspect of the present invention, that is the width w of the second snap fit 52
2Not necessarily need the width w greater than the first snap fit 51
1, in other embodiments of the invention, also can there be other form to prevent that middle frame structure 50 is installed in the process of body 60, the second snap fit 52 mistakes are sticked in the problem of the first draw-in groove 61.For example as long as the width w of the second snap fit 52
2When the second snap fit 52 moves along installation direction I, not can with the width w of the first draw-in groove 61
1Fully overlappingly (or fall into width w fully
1In) get final product, in other words, as long as the two side 612,613 of the first draw-in groove 61 one of them angle along installation direction I at least can fall between the limit, left side 522 and right edge 523 of the second snap fit 52, can guarantee that the second snap fit 52 can not engage with the first draw-in groove 61 mistakes.
In addition, two snap fits of middle frame structure also can have other different designs, as shown in the middle frame structure 80 of another embodiment of Figure 10, the first snap fit 81 and the second snap fit 82 have respectively the first cantilever 814 and the second cantilever 824, the opening 84 or the groove that have L-type between the first snap fit 81 and the second snap fit 82, therefore two snap fits 81,82 are also for having independently cantilever design.
Please refer to Fig. 8 and Fig. 9, wherein Fig. 8 is the local side schematic diagram along x-x ' tangential direction of the portable apparatus 2 of Fig. 4, and Fig. 9 is that portable apparatus 2 is along the cut-open view of the three-dimensional viewpoin of x-x ' tangential direction.The double card of portable apparatus 2 housings 200 hooks design and utilizes dual limiting displacement condition, in the degree of freedom of restraining coupler construction with when reaching the tamper effect, separately can allow the dimensional parameters appropriateness between snap fit and corresponding draw-in groove to amplify, put in place in order to the manufacturing demoulding and the assembling of part.In Fig. 8, the first snap fit 51 is with after the first draw-in groove 61 engages, the gap d that the wall of its inclined-plane 511 and the first draw-in groove 61 is 611
1And tiltangleθ
1, and the second snap fit 52 is with after the second draw-in groove 62 engages, the gap d that the wall of its inclined-plane 521 and the second draw-in groove 62 is 621
2And tiltangleθ
2All can appropriateness amplify, and need not worry easily rock or be disassembled by human factor or problem that natural pine drags as single snap fit.The gap d that appropriateness is amplified
1, d
2And tiltangleθ
1, θ
2The demoulding that is conducive to middle frame structure 50 is produced with manufacturing, and more easily assembling puts in place.In addition, engage the reverse direction D at place with draw-in groove at the first snap fit 51 (or second snap fit 52)
2On, an another extensible support column 53, when middle frame structure 50 was installed on body 60, accommodating electronic installation 300 within it can be along D
1Direction only props up support column 53, makes the first snap fit 51 be subjected to the F strength of electronic installation 300 only to support and unlikelyly come off from the first draw-in groove 61, increases the firm of engaging.
The portable apparatus that the present invention has disclosed a kind of multiple fastening structure housing and had this kind housing, on the middle frame structure and body of housing, utilize double card to hook the design that engages simultaneously with the double card groove, the bond strength of increase middle frame structure and body, and have advantages of and be easy to make and assemble.The first snap fit and second snap fit of middle frame structure have independently cantilever, and sequentially arrange along an installation direction axis at grade, and the first draw-in groove on body and the second draw-in groove are also sequentially arranged along this installation direction axis at grade, when snap fit engages respectively corresponding draw-in groove, the second snap fit can not fall into the first draw-in groove fully along this installation direction, is sticked in the problem of the first draw-in groove to prevent the second snap fit mistake in installation process.
The above is only preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
