Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
With the development of electronic technology, various electronic devices are widely applied to various fields, however, if water enters the electronic devices in the using process, the electronic devices can break down, and further have abnormal functions, so that the waterproof measures of the electronic devices are particularly important. The waterproof mode commonly used at present is to set up waterproof shell with the electronic equipment outside to solve the inside problem of intaking of electronic equipment. The shape and size of the waterproof housing are matched with those of the electronic device, and the waterproof housing has different shapes according to different requirements, and the structure of the waterproof portion of the waterproof housing is only described in detail in the embodiments of the present application.
Referring first to fig. 1, fig. 1 is a partial structural schematic diagram of a conventional waterproof case 900.
Traditional waterproof case 900 includes casing 910, casing 920 and waterproof piece 930 down usually, goes up casing 910 and casing 920 and laminates mutually, and goes up casing 910 and casing 920 and be equipped with recess 940 on the surface that last casing 910 and casing 920 laminated mutually, and waterproof piece 930 locates in recess 940 in order to carry out elasticity to last casing 910 and casing 920 and support, thereby reaches water-proof effects. However, in the conventional waterproof case 900, the contact area between the waterproof member 930 and the upper case 910 and the lower case 920 is relatively large, when the upper case 910 and the lower case 920 press the waterproof member 930, in order to achieve a corresponding compression amount, the pressing force required to be used is relatively large, and since the force is applied to each other, the resilience of the waterproof member 930 to the upper case 910 and the lower case 920 is also relatively large, and the excessive resilience easily causes the reduction of the degree of attachment between the upper case 910 and the lower case 920, thereby causing the waterproof failure of the conventional waterproof case 900, and reducing the waterproof disposable straight-through yield of the conventional waterproof case 900.
Moreover, because the contact area between the waterproof member 930 and the upper shell 910 and the lower shell 920 is large, the adhesion degree between the waterproof member 930 and the upper shell 910 and the lower shell 920 is greatly affected by the surface quality of the upper shell 910 and the lower shell 920, when the upper shell 910 and the lower shell 920 are rough in surface and have more pits or scratches, the adhesion degree between the waterproof member 930 and the surfaces of the upper shell 910 and the lower shell 920 is reduced, so that the waterproof effect of the conventional waterproof shell 900 is poor, and the waterproof one-time direct connection yield of the conventional waterproof shell 100 is reduced.
Referring to fig. 2, fig. 2 is a schematic partial structural view of a waterproof housing 100 according to an embodiment of the present disclosure.
An embodiment of the utility model provides a waterproof casing has better water-proof effects, and has higher waterproof once only directly yields. This waterproof casing includes first casing 10, second casing 20 and first waterproof piece 30, first casing 10 lid closes on second casing 20, first casing 10 includes first surface 101, second casing 20 includes second surface 201, first surface 101 laminates with second surface 201 mutually, the concave first recess 11 that is equipped with on first surface 101, the inner wall of first recess 11 and second surface 201 enclose to close and form first holding chamber 110, first waterproof piece 30 is located in first holding chamber 110, the chamber wall epirelief of first holding chamber 110 is equipped with first boss 40, first boss 40 extrudees first waterproof piece 30 so that first waterproof piece 30 supports with the chamber wall elasticity of first holding chamber 110 and holds.
The waterproof finger of the waterproof housing 100 is not only for preventing water from entering, but also for preventing other arbitrary liquids from entering, such as oil, salt water, etc., and is not described herein any more, and for convenience of description, the embodiment of the present application only uses water as an example for detailed description.
The first housing 10 and the second housing 20 are made of waterproof material, such as plastic, steel, etc., so as to prevent water from penetrating into the first housing 10 or the second housing 20 to cause malfunction of the electronic device. It is understood that the waterproof materials used for preparing the first casing 10 and the second casing 20 include, but are not limited to, the above materials, and may also be made of any other waterproof materials meeting the corresponding requirements, which are not described in detail herein.
