Abstract
In a clamshell housing, such as is used for portable devices, engaging elements other than screws or hooks are employed to prevent the two halves of a clamshell housing from having significant slippage between them along the interface at which they meet when the clamshell is subjected to bending and/or torsional moments. Such engaging elements may include slip preventing elements at the clamshell halves interface, e.g., various forms of interlocking teeth, elements that increase friction, or the like, which are added to, or molded into, each half of the housing. By restricting relative motion along the plane of the interface, the propensity to separate along the direction perpendicular to the interface plane is reduced. This is achieved because the restriction of the relative motion increases the bending and torsional rigidities.
Description
The present invention relates to a kind of case design, in particular to the housing that is used for portable electron device.
In the portable electron device field of for example phone, paging device, electronic device, calculator, handheld game machine, remote controller and computer etc., tend to make these products littler, lighter and more cheap.Consequently, just adopt at present thin and lighter plastics to make housing, thereby when making bending force that housing synthesized and twisting resistance when it falls, be easier to bending and distortion.
The design principle relevant with this type of mancarried device must not be any screw that exposes.This is in order to prevent that the user from opening this device.Therefore, make screw be positioned at the battery below usually, so that it is exposed.In addition, need spended time and labour cost is increased owing to insert screw, so require to reduce the quantity of used screw.Project organization that in fact, occur on the market or that just preparing to put on market has only adopted an independent screw.
Because device size is less, need increase the useful space of electronic circuit as much as possible, and not wish that very big joint element is arranged.But, still require the two halves of housing controllably to separate, for example take apart, so that to wherein element place under repair or test.
People generally acknowledged the design principle of this type of mancarried device be should avoid each corner of this device and the centre of long lateral margin screw is set.Therefore, when mancarried device drops, be easy to produce tangible relative motion, promptly the interface along its joint produces slip between the two halves of clamshell shape housing.If this thing happens, the possibility that just exists housing or its part to throw open promptly the gap will occur at the interface.When even be molded into the jack of grab and coupling in the two halves of housing the two halves housing being fixed together, above-mentioned situation also can take place, and this is because synthetic crooked and/or reverse grab is got loose.In addition, in this device, battery helps the housing of stiffening device.But when this device dropped, battery was easy to, and made more possibility deflection deformation of housing.
Therefore, according to principle of the present invention, adopt the joint element except that screw or grab, when being subjected to bending and/or torsional moment with convenient clamshell shape housing, the two halves that prevent clam shell shape housing produce tangible relative motion along the interface of its contact.Described joint element can be included in the anti-slip element at the interface of clamshell shape two halves, as the element or the like of various types of zigzag tooths, increase friction, these elements is attached to or is injection-moulded in each half housing of housing.Along the relatively moving of interface plane, reduce the tendency of separating by restriction along perpendicular to interfacial direction.Because the restriction relative motion has increased bending stiffness and torsional rigidity, thereby has realized above-mentioned purpose.

Fig. 1 shows the typical clamshell shape housing 101 that embodies the principle of the invention.Clamshell shape housing 101 shown in Figure 1 has two housing one side of something separately, and housing 101 shown in Figure 2 has two housing one side of something that are combined together.Housing 101 is made up of upper shell 103 and lower house 105.Adopt screw 107 that upper shell 103 and lower house 105 are coupled to each other together to form the clamshell shape housing.Screw 107 preferably be located at housing 101 surfaces the centre and with this Surface Vertical.In upper shell 103, be molded with tooth 109 and last teeth groove 111.Equally, in lower house 105, be molded with lower tooth 113 and following teeth groove 115.The shape of the tooth on upper shell 103 and the lower house 105 matches each other, and like this when upper shell 103 and lower house 105 are coupled to each other together, the tooth on a housing one side of something is packed in the groove on another housing one side of something.This assembly structure as can see from Figure 2.Advantageously, work as moment, when acting on the clamshell shape housing 101, will prevent from that upper shell 103 and lower house 105 from having significantly betwixt to relatively move that this will increase the bending stiffness and the torsional rigidity of clamshell shape housing 101 as twisting resistance or bending force.
Although tooth and groove are to be provided with along the whole periphery of upper shell 103 and lower house 105 respectively in Fig. 1 and Fig. 2, and nonessential so.She Ji advantage is like this: it allows to do the degree of depth of tooth and groove more shallow.But, might be only tooth and groove be set along a part of side of each housing one side of something.Fig. 3 shows the housing 301 of configuration like this.If tooth and groove be only along a part of side setting of each housing one side of something, the degree of depth when suggestion is done the degree of depth of tooth and groove to such an extent that be provided with greater than its whole side along each housing one side of something.If limit the part on the half and half avris limit that is provided with tooth and groove, tooth and groove preferably should be positioned at crooked or reverse the place of weak position at a distance of farthest coverage, for example, at barycenter coverage place farthest, be easy to maximum bending take place or reverse around this weak part apart from above-mentioned mancarried device.Apart coverage farthest means as far as possible away from the barycenter in the housing, so that be not subjected to the obstruction of the further feature or the interior any circuit element of device of housing.Usually, for housing, coverage farthest is the corner at housing.In Fig. 3, can be clear that this configuration.In addition, tooth and groove should be positioned at bending or reverse weak position.
The size of the tooth that is adopted also is the quality of device and the torsional strength that must bear or the function of bending force.Described quality reflects with the weight of device usually, and torsional strength or bending force value are determined by the height of fall of device usually.Should be noted in the discussion above that when device drops the other factors that influences twisting resistance that device bears or bending force is a) rigidity of shell structure, b) make the material of housing, c) drop thereon surface of housing, the d) orientation of housing when impacting, e) shape of housing, and the f) size of housing.
And do not require tooth is made as shown in Figures 1 to 3.In addition, do not require yet and to see tooth from the outside of clamshell shape housing.Really, according to existing aesthetic view point, preferably cannot see tooth from the outside of clamshell shape housing.Also have, when the side of housing tilts with respect to vertical direction, may not can have the tooth of the effective interlocking that can see from the outside.Therefore, according to an aspect of the present invention, staggered tooth is arranged on the inboard of the visible exterior of clamshell shape housing.In addition, both needn't in each half shell of clamshell shape housing, all make tooth and be used to admit the groove of tooth, also needn't be necessarily as shown in Figures 1 to 3 by over-over mode configuration tooth and groove.
In addition, can adopt other shape and structure as staggered " tooth ".In addition, according to other design constraint, can mix and mate flute profile.Fig. 4,5 and 6 shows adoptable various types of tooth and groove.Tooth that Fig. 4 represents and the tooth shown in groove and Fig. 1 to 3 and groove are similar, but tooth and groove are configured in the inboard of housing, just can't see this tooth and groove from its outside like this.Fig. 5 shows internal tooth 509, this tooth can be assemblied in one by two from the groove that the rib 521 and 523 of inboard 527 projectioies of a housing one side of something forms.When the half of joint of two housings, can not see internal tooth 509 from the outside 529 of housing one side of something.Fig. 6 shows according to the tooth in one aspect of the present invention embedding groove.
Fig. 7 shows its structure tooth identical with Fig. 5, just comprises on the surface of housing one side of something 503 of tooth 509 being molded into a step 731, and also be molded into a step 733 on the surface of opposed housing one side of something 505.The purpose that step 731 and 733 are set is to prevent that the space that can spy on is arranged between the housing two halves.So even may have a gap between the two halves of housing, for example the gap 835, but because the step that is molded into is arranged, other people can not spy on inside by this gap.Those of skill in the art can recognize, this step can be located in the housing with any tooth and groove arrangement.Fig. 8 shows according to the tooth in one aspect of the present invention embedding groove.Pillar 909 among Fig. 9 is with the dimension reduction of tooth 509 (Fig. 5) result to the size of pillar, also can be referred to as rib.Can notice that pillar 909 is similar with rib 521 and 523.
It should be noted, for some applications, can be in the relative motion between the two halves of the direction of two axis in the interface upper edge of clamshell shape housing two halves restriction housing.Therefore, the setting of the corresponding recesses that forms according to tooth with by rib can only need have a rib.In addition, on the interface of housing one side of something, each tooth need not limit along the multidirectional of each axis and move.The substitute is, indentation limitations the moving that can adopt one first tooth and be complementary along first direction, and the indentation limitations that can adopt one second tooth and coupling is drawn analogous conclusions, till all need the direction of constrained motion all to be tied along the moving of other direction.
Figure 10 to 12 shows various teeth and the groove that uses with double-walled construction according to an aspect of the present invention.Because the quality when the employing double-walled construction has increased the rigidity of housing and compared the thickness that merely increases solid wall is little, so double-walled construction is effectively.This class formation has been shown among Figure 10 and 11.When one gasket seal of employing at the interface at two housings one side of something, double-walled construction also is effectively.Can adopt so a kind of pad to reduce electromagnetic interference (EMI) or radio frequency interference (RFI).
Figure 12 shows the layout of the clamshell shape housing that is used to limit mobile height friction elastic washer 1221 according to an aspect of the present invention.In Figure 12, small embossment 1209 is with the dimensional contraction of tooth 509 (Fig. 5) result to this protruding size.Packing ring 1221 squeezes between the surface of small embossment 1209 and the groove 1241 that is complementary, so that very high friction to be provided between two surfaces.Preferably also duplicate such small embossment along the interface between the housing two halves.Also may need to be provided with small rut 1241 (not shown)s in groove 1215, this small rut is to form when matching substantially with the dimensional contraction of groove 515 so that with small embossment 1209.
Double-walled construction and double-walled shape structure can may be reduced or remitted necessity that tooth and groove are set along the different sides of housing along an additional axis constrained motion.Adopt the double-walled construction of Figure 10 to 12, can produce above-mentioned restriction.In addition, Figure 13 to 15 shows the double-walled shape structure with same effect.
Gap between tooth and groove is preferably less with respect to the size of coupling member.For example, for cell-phone, have been found that the gap is useful when being 0.1 to 0.2mm.
Figure 16 to 19 shows the shell structure that adopts tooth and groove according to the present invention, and this structure also has such attendant advantages, and the coupling mechanism force perpendicular to shell interface promptly is provided.More specifically, tooth 1609 is made a clip that engages with groove 1619 (snap).Gap 1651 allows the two halves of clip 1609 to be moved towards each other when clip being inserted groove 1615 or take out from groove, thereby the two halves 1603 of housing can be engaged and separate with 1605.Figure 17 shows the housing two halves 1603 and 1605 that engage by means of the clip 1609 that inserts in the groove 1615.Figure 18 shows and similar one embodiment of the present of invention shown in Figure 16, just uses the gap between pillar 1861 to replace groove 1615.The advantage of pillar is the wall attenuate on the whole that allows housing.Figure 19 shows two halves 1603 and the 1605 interlocking views that engage that make housing by means of the clip 1609 that is inserted in the gap between two pillars 1861.
