Seal structure of mobile phone protective shell

Abstract

The invention belongs to the dustproof, shockproof and waterproof product field and relates to a seal structure of a digital electronic product such a mobile phone, a mobile phone protective shell, a tablet computer, a handheld terminal product, a smart band, a smart watch, a health care electronic product and a smart home electronic product. The seal structure includes a face shell and a bottom shell; the inner side of the frame of the face shell is provided with a plurality of annular grooves, the width of the annular grooves ranging from 0.5 mm to 2 mm; the inner side of the frame of the bottom shell is provided with a plurality of annular projections, the width of the annular projections ranging from 0.6 mm to 2.1 mm; and the plurality of annular projections of the frame of the bottom shell are engaged with the plurality of annular grooves of the frame of the face shell in a staggered manner. The plurality of annular projections of the frame of the bottom shell are embedded into the plurality of annular grooves of the frame of the face shell, so that a reliable protection function can be realized, and the protection level can achieve IP67, any waterproof rubber gaskets are not required. The seal structure has the advantages of low production cost and high efficiency. With the seal structure adopted, a mobile phone product can be designed into a fashion, light and slim product.

Description

technical field [0001] The invention belongs to the application field of three-proof products, and relates to the sealing structure of digital electronic products such as mobile phones, mobile phone protective cases, tablet computers, handheld terminal products, smart bracelets and watches, medical and health care electronic products, and smart home electronic products. Background technique [0002] To achieve a good waterproof and dustproof function of the mobile phone, it is necessary to reliably seal all the gaps between the mobile phone or the protective case of the mobile phone. area, camera area, power button area, volume button area. At present, mobile phones or mobile phone protective cases with three-proof functions use waterproof rings, and at the same time, screws or large-area buckles are used to make the surface shell and the bottom shell press the waterproof rings together to achieve waterproofing. Therefore, this design method costs High, difficult, many hidd...
