In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and for example, can be to be fixedly connected with, and can be also to removably connect, or connect integratedly; Can be mechanical connection, can be to be also electrically connected to; Can be to be directly connected, also can indirectly be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, can concrete condition understand the concrete meaning of above-mentioned term in the utility model.
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Fig. 5 to Fig. 8, the utility model provides a kind of cell phone rear cover load module, comprising:
Bonnet housing 203 and battery cover 201, battery cover 201 covers on bonnet housing 203, described battery cover 201 comprises integrated ebonite portion 2011 and flexible glue portion 2012, flexible glue portion 2012 is arranged on the periphery of ebonite portion 2011, described flexible glue portion 2012 comprises at least 2 road elastic packing walls 2013, the region that elastic packing wall 2013 is arranged on flexible glue portion 2012 surroundings and covers with described bonnet housing 203, on bonnet housing 203, be provided with some protruding (not shown)s, elastic packing wall 2013 is between two adjacent projections, and elastic packing wall 2013 surrounds a closed cavity 204 with described bonnet housing 203 and flexible glue portion 2012.
The utility model provides a kind of cell phone rear cover load module, wherein battery cover 201 adopts integrated ebonite portion 2011 and flexible glue portion 2012 structures of comprising, and there are at least 2 road elastic packing walls 2013 at the region division that flexible glue portion 2012 surroundings and described bonnet housing 203 cover, adopt multi-layer sealing structure, can be effectively and water-tight reliably; And on bonnet housing 203, be provided with some projections, elastic packing wall 2013, between two adjacent projections, can prevent that elastic packing wall 2013 from moving up and down, and plays the fixedly effect of elastic packing wall 2013, plays further the effect of waterproof and sealing.Simultaneously, because battery cover 201 adopts integrated structure, with respect to prior art, reduced the assembling of sealing ring, do not need the interference fit between sealing ring and rear cover body housing and battery cover, therefore it is simple in structure, assemble easyly, improved production efficiency, reduced the requirement to precision in product processing.
As the preferential execution mode of the present embodiment, elastic packing wall 2013 is for being arranged on the convex edge circle of flexible glue portion 2012 surroundings.This convex edge circle adopts flexible glue material to make, and has elasticity, under the effect of power, elastic deformation can occur, it is along the 2012 surrounding settings of flexible glue portion, thereby bonnet housing 203 and flexible glue portion 2012 are closely cooperated, form a closed cavity 204 together with the circle of convex edge, thereby work the effect that reaches waterproof.
Advantageously, convex edge circle is cambered surface with bonnet housing 203 contact portions, and the design of cambered surface convex edge circle occurs after elastic deformation more abundant with contacting of bonnet housing 203, better tightness.
Advantageously, convex edge circle is shaped as semicircle, half elliptic or parabola shaped along its cross section radially.
Advantageously, the material of flexible glue portion 2012 and elastic packing wall 2013 is TPU(Thermoplastic polyurethanes, TPUE rubber) or TPE(Thermoplastic Elastomer, thermoplastic elastomer (TPE)).
Advantageously, the material of described ebonite portion 2011 is PC(Polycarbonate, Merlon).
Advantageously, elastic packing wall 2013 can have a plurality of, its spacing distance is each other greater than the radial diameter that described elastic packing wall 2013 occurs after elastic deformation, in order to avoid occur elastically-deformable time at elastic packing wall, between the elastic packing wall that causes facing mutually due to hypotelorism, push, and then affect sealing property.
Same, another preferential execution mode as the present embodiment, convex edge circle can have a plurality of, its spacing distance is each other greater than described convex edge circle the radial diameter after elastic deformation occurs, in order to avoid when convex edge circle generation is elastically-deformable, between the convex edge circle that causes facing mutually due to hypotelorism, push, and then affect sealing property.
When assembling, cell phone rear cover load module of the present utility model is because battery cover 201 adopts integrated structure, only battery cover 201 and bonnet housing 203 need to be covered mutually, do not need to realize sealing by repeatedly adjusting the size of battery cover, back cover housing and these three parts of flexible seal ring, reduce the required precision to process equipment, improved productivity ratio; And reduced flexible seal ring, and saved secondary assembling, assembling is become and more simplify.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or feature can be with suitable mode combinations in any one or more embodiment or example.
