Abstract

The utility model relates to an electronic device which comprises a casing body, a key body and a waterproof piece, wherein the casing body is provided with an opening and the key body is arranged at the opening. The waterproof piece is arranged in the casing body in a surrounding opening mode, and is butted with the key body so as to cover the opening.

Description

Electronic installation

Technical field

This is novel to relate to a kind of electronic installation, particularly relates to a kind of electronic installation with waterproof construction.

Background technology

With reference to Fig. 1, electronic installation 10 generally comprises a housing 11 and a button or button 12, can be used to manipulate or regulate the function of electronic installation 10, because button 12 is to connect electronic installation 10 inside and component external, just be provided with an opening 111 on the housing 11 so that button 12 passes through, button 12 then is arranged at opening 111 places.

In order to make button 12 be convenient to rotate up and down or push, opening 111 must have certain width, as does not have special waterproofing design, just rainwater or other liquid are flowed into the inside of electronic installation 10 easily by opening 111 places.

If liquid flows to electronic installation inside, the damage and the fault of inner body will be caused.Usually be used in indoor electronic installation and do not need to do the consideration of waterproof construction, but the generalization of portable electron device in recent years (for example mobile phone, MP3, camera etc.), promoted the demand to water-proof function greatly, especially the electronic installation of sports type is all the more so.

Novel content

This novel purpose is to provide a kind of electronic installation, and it can utilize the design that improves opening part to reach the effect of waterproof.

Novel according to this, a kind of electronic installation is provided, comprise a housing, a key body and one first waterproof case.Housing forms an opening, and the key body is arranged on opening part, and first waterproof case is arranged at housing in the mode around opening, and with key body butt, to hide opening.

Electronic installation also comprises one second waterproof case, is arranged at housing in the mode around first waterproof case, and the height of second waterproof case is greater than the height of first waterproof case, and less than the height of key body.

In a preferred embodiment, first waterproof case and second waterproof case are made by elastomeric material.

In another preferred embodiment, elastomeric material is a soft rubber.

In addition, the key body has one first one and one second one, and housing has one first and one second, first one side that is positioned at first, and second one side that is positioned at second, wherein second one can be passed opening and be connected with first one.

In a preferred embodiment, first waterproof case and second waterproof case are arranged at first.

In another preferred embodiment, an equidistant from distance less than 0.05mm is kept on second and second one's surface.

In another preferred embodiment, second cooperates second one shape to form an arc surface.

In another preferred embodiment, electronic installation is a MP3.

In another preferred embodiment, the key body is that the First Five-Year Plan is to key.

In order to make this novel above-mentioned and other purpose, feature and advantage can more obvious easy to understand, below especially exemplified by preferred embodiment, and conjunction with figs. elaborates.

Description of drawings

Fig. 1 is the profile of known electronic installation;

Fig. 2 is the waterproof construction schematic diagram of this novel electron device;

Fig. 3 is the waterproof construction profile of this novel electron device.

Embodiment

With reference to Fig. 2 and Fig. 3, this novel electronic device 20 is a MP3, comprise a housing 21, a key body 22, one first waterproof case 23 and one second waterproof case 24, it should be noted, this novel electronic device is a MP3, but be not limited thereto, electronic installation also can be a mobile phone, a camera or a PDA etc.

Housing 21 forms an opening 211, key body 22 is arranged at opening 211 places, and its middle shell 21 has one first 21a and one second 21b, and key body 22 has one first 22a and one second 22b, and first 22a is positioned at one side of first 21a, and second 22b is positioned at one side of second 21b.

Second 22b can pass opening 211, and is connected with first 22a, but is not limited thereto, and also can be that first 22a passes opening 211, and be connected with second 22b.

Second 22b is a convex structure body, and forms arcwall face in the position with respect to second 21b; Second 21b forms a depressed part R at opening 211 places, and cooperates second 22b to form a cambered surface, and both arcwall faces keep an equidistant from distance less than 0.05mm, makes second 22b can abut against second 21b and slides.

First waterproof case 23 is made by soft rubber, be arranged on first 21a of housing 21 in mode, and form an arcuate surface towards the direction of 22 first 22a of key body around opening 211, until with first 22a butt, and hide opening 211, be close to the surface of first 22a again and extend a bit of distance.

Second waterproof case 24 is one to be projected on the slab organization of first 21a, be arranged at housing 21 in mode around first waterproof case 23, wherein the height H 24 of second waterproof case 24 is greater than the height H 23 of first waterproof case 23, but less than the height H 22 of 22 first 22a of key body.

Because second waterproof case 24 is higher than first waterproof case 23, can prevent a large amount of liquid splash to the first waterproof cases 23 and the bonding part of first 22a, relative, second waterproof case 24 is lower than first 22a, do not hinder the action of key body 22 yet, make second waterproof case 24 become this novel first road waterproof measure.First waterproof case 23 and first 22a are close to, and prevent that liquid from directly entering housing 21 by opening 211, and then make first waterproof case 23 become this novel defence line, second road.Further explanation, because first waterproof case 23 is made by soft rubber, when 22 actions of key body, first waterproof case 23 can cooperate with key body 22, does not influence the activity of key body 22.

It should be noted that second waterproof case 24 can be provided with according to the waterproof degree, little for the waterproof demand as this electronic installation, then first waterproof case 23 has had enough waterproof measures, does not need to add second waterproof case 24 again.

In addition, when key body 22 reverses, minimum gap might appear between first waterproof case 23 and first 22a, during as careless manipulation, the gap inlet opening 211 of small amount of liquid from first waterproof case 23 and first 22a will be arranged, but, can further prevent liquid infiltration electronic installation 20 inside, to reach the three lines of defence of waterproof because second 22b is minimum with the space between second 21b.

Disclose with preferred embodiment though basis is novel; but be not novel in order to limit this, any those skilled in the art is not breaking away under this novel design and scope situation; can make and changing and retouching, therefore this novel protection range is defined with accompanying claims.
