Description

Shell structure

Technical field

The relevant a kind of shell structure of the present invention, particularly relevant a kind of case of electronic device structure with waterproof construction.

Background technology

Referring to Fig. 1, known case of electronic device structure 10 comprises a upper shell 11, a lower house 12 and a waterproof case 13.Waterproof case 13 have one around the 13C of portion and with around the integrally formed protuberance 13P of the 13C of portion.Around the 13C of portion along shell structure 10 around being arranged at upper shell 11 and lower house 12 edges, protuberance 13P then corresponds respectively to the sealed place of

lower house

11,12, when upper shell 11 combined by closure 14 with lower house 12, waterproof case 13 can prevent that liquid or aqueous vapor are by entering shell structure 10 inside between the last

lower house

11,12.

Referring to Fig. 2, because the rubber that is one of the forming around the 13C of portion and protuberance 13P of normally used waterproof case 13 is made, therefore when upper shell 11 combines with lower house 12, closure 14 applies axially sealed pressure when protuberance 13P, to be compressed to around the 13C of portion and make and be out of shape around the 13C of portion, thereby cause

lower house

11,12 can't cooperate closely with waterproof case 13, thereby the possibility that causes the electronic installation infiltration is still arranged, and can't reach the purpose of complete waterproof.

Summary of the invention

In view of this, the invention provides a kind of shell structure, comprise a upper shell, a lower house, one first waterproof case and one second waterproof case.Upper shell has one first connecting portion, lower house has one second connecting portion, first waterproof case is arranged between first connecting portion and second connecting portion, and second waterproof case is arranged between first connecting portion and second connecting portion, wherein has a distance between first waterproof case and second waterproof case.

Shell structure of the present invention has design excellent waterproof structure, and first waterproof case and second waterproof case are brought into play the function of waterproof separately, prevent that fully liquid or aqueous vapor from entering in the confined space, protection internal electron part.Compare with known housing with integrally formed waterproof case, be formed with a distance between first waterproof case of the present invention and second waterproof case, that is to say that first waterproof case and second waterproof case are stand-alone assembly, when therefore sealed, only bring pressure to bear on second waterproof case, first waterproof case can't be influenced by it and be out of shape, and therefore can more effectively reach the purpose of complete waterproof.

Embodiment

Referring to shown in Figure 3, shell structure 100 of the present invention can be applicable to general electronic products, for example electronic products such as mobile phone, PDA(Personal Digital Assistant) or electronic dictionary.The shell structure 100 of a preferred embodiment of the present invention comprises a upper shell 110, a lower house 120, first waterproof case 130, a plurality of second waterproof case 140 and an a plurality of closure 150, can be when wherein upper shell 110 combines with lower house 120 in the shell structure 100 inner confined space S that form, be used to hold accurate electronic component, can prevent fully that by first waterproof case 130 and second waterproof case 140 liquid and aqueous vapor from entering in the confined space S, prevent that electronic component from making moist.

Figure 4 shows that the phantom when shell structure 100 is sealed.Wherein upper shell 110 has one first connecting portion 111, and first connecting portion 111 has one first outer rim 111C, a perforation 111H and one first a groove N1; Lower house 120 has one second connecting portion 121, and second connecting portion 121 has one second outer rim 121C, a locking part 121N and the first groove N1.Wherein, first groove N1 of first connecting portion 111 and the first groove N1 of second connecting portion 121 corresponding formation mutually, and first waterproof case, 130 outstanding being arranged among the first groove N1 of first connecting portion 111 or second connecting portion 121.

When shell structure 100 is sealed, closure 150 is sealed from the locking part 121N that upper shell 110 passes perforation 111H and lower house 120, so as to upper shell 110 is fixing with lower house 120, and will for example closely be folded between the first groove N1 of upper shell 110 and lower house 120 for first waterproof case 130 of elastomeric material.Simultaneously, first outer rim 111C of upper shell 110 and the second outer rim 121C of lower house 120 can be in contact with one another, and in the shell structure 100 inner confined space S that form.In this example, because first waterproof case 130 is not integrally formed with perforation 111H or locking part 121N, therefore, can not cause and pull first waterproof case 130 because of sealed pressure and cause distortion, the phenomenon that aqueous vapor is infiltrated though closure 150 still can have the pressure that axially presses down because of sealed.

In order to reach tighter waterproof measure, first connecting portion 111 and second connecting portion 121 also comprise one second groove N2, are formed at the periphery of perforation 111H with ring-type, and second waterproof case 140 is outstanding is arranged among the second groove N2.When closure 150 passes perforation 111H and locking part 121N when sealed, second waterproof case 140 will closely be folded between upper shell 110 and the lower house 120.

In this example, second waterproof case 140 can be a ring-shaped rubber packing ring, is arranged among the second groove N2.It should be noted, because second waterproof case 140 is that rubber is made, can be when upper shell 110 combines with lower house 120, closely cooperate with last lower house 110,120 respectively, therefore the setting that can omit the above-mentioned second groove N2 is perhaps only selected one at first connecting portion 111 and second connecting portion 121 the second groove N2 is set.In addition, above-mentioned second waterproof case 140 can cooperate the quantity of perforation 111H and locking part 121N and be provided with, and its quantity does not limit.

Second waterproof case 140 in this example also is a free ring around being arranged on around the perforation 111H, and it is not integrally formed with first waterproof case 130, therefore when closure 150 after axially pressing down, with the unlikely driving fit that influences first waterproof case 130, can avoid aqueous vapor near first waterproof case 130 of pullling distortion, to infiltrate electronic installation 100, and second waterproof case 140 that is arranged on around the perforation 111H more can be brought into play blocking effect, avoids aqueous vapor to enter in the confined space S from the finedraw of closure 150 with perforation 111H.

Compare with known housing with integrally formed waterproof case, in a preferred embodiment of the present invention, have one apart from G between first waterproof case 130 and second waterproof case 140, that is to say that first waterproof case 130 and second waterproof case 140 are stand-alone assembly, when therefore closure 150 and locking part 121N are sealed, only bring pressure to bear on second waterproof case, 140, the first waterproof cases 130 and influenced by it and be out of shape, can more effectively reach the purpose of complete waterproof.

Though the present invention discloses as above with preferred embodiment; yet it is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; without departing from the spirit and scope of the present invention; when can doing all changes that is equal to and retouching, so protection scope of the present invention is when looking being as the criterion that claims define.
