Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, these embodiments are provided to explain the principles of the invention and its practical application to thereby enable others skilled in the art to understand the invention for various embodiments and with various modifications as are suited to the particular use contemplated.
the present invention provides an electronic device (for example, a smart watch) as shown in fig. 2, which includes a metal front shell 10 and a transparent upper cover 20, wherein the metal front shell 10 and the transparent upper cover 20 enclose an accommodating space 30 for assembling electronic components (not shown in the figure); an elastic member 40 is further interposed at a junction area between the metal front case 10 and the transparent upper cover 20.
the elastic member 40 can be just clamped between the metal front shell 10 and the transparent upper cover 20, so as to connect the metal front shell 10 and the transparent upper cover 20 and prevent moisture from entering the accommodating space 30.
For example, the material of the metal front case is aluminum or stainless steel (SUS); the transparent upper cover is made of glass; the sealing element can be made of polypropylene (PP), polytetrafluoroethylene (Teflon) or thermoplastic polyurethane elastomer rubber (TPU).
Preferably, further optimizing the technical effect of the present solution, the shape parameters of the elastic member 40 are further improved. As shown in FIG. 3, the length of the elastic member 40 can be customized according to the shape of the electronic device, and the cross section of the elastic member 40 parallel to the short axis direction is approximately rectangular, the width thereof is 0.36-0.45 mm, and the height thereof is 0.7-0.9 mm.
In order to improve the connection performance between the elastic member 40 and other devices, two opposite corners of the elastic member 40 on the diagonal line are chamfered, preferably at 35 °, and the cutting width is 0.15 mm.
In order to optimize the performance of the elastic member 40, the structure of the metal front shell 10 is modified, and as shown in fig. 2 and 4, the metal front shell 10 includes: a bottom plate 11 and side walls 12.
Specifically, the bottom plate 11 extends out of the side wall 12 towards the transparent upper cover 20, and the side wall 12 and the bottom plate 11 are integrally formed. A gap is left between the side wall 12 and the side of the transparent upper cover 20 for inserting the elastic member 40.
As shown in fig. 4, the side wall 12 extends toward the accommodating space to form a shelf 121 for placing the transparent upper cover 20, and preferably, as shown in fig. 5, an overlapping width between the shelf 121 and the transparent upper cover 20 is not less than 0.15mm, so that the transparent upper cover 20 can stably rest on the shelf 121 of the side wall 12.
An elastic portion is recessed from the surface of the shelf 121 toward the sidewall 12 for elastically deforming the sidewall 12 during the insertion of the elastic element 40.
Wherein, the elastic part includes: a buffer 123 and a recess 124.
the buffer platform 123 is disposed on the surface of the shelf 121, and is adjacent to the inner side of the side wall 12. For example, the height of the buffer stage 123 relative to the shelf 121 is 0.05 mm.
The groove 124 is disposed above the buffer stage 123. The shape is similar to that of a triangle formed by splitting a gap from a knife to the direction of the buffer table and towards the side wall. The top wall of the groove 124 forms an acute angle with the plane of the cushion 123. The forming shapes of the included angle and the groove are determined according to the requirement of the thickness of the side wall, for example, the included angle is 60 degrees; the depth of the groove is 0.15 mm.
in order to achieve the waterproof purpose, the transparent upper cover and the elastic piece form interference fit, and the interference amount is 0.05-0.07 mm; for example, the difference in height between the top surface of the elastic member and the top surface of the side wall before the elastic deformation is not generated is larger than 0.05mm, and the deformation amount after the elastic member is engaged with the transparent upper cover is 0.07 mm.
During assembly, the elastic piece 40 is firstly placed on the placing platform of the metal front shell and is abutted against the inner side of the side wall of the metal front shell; and then the transparent upper cover is assembled on the metal front shell provided with the elastic piece. The side wall of the metal front shell is provided with an elastic part, and a certain elastic deformation space can accommodate the pressing-in of the transparent upper cover. When the transparent upper cover is pressed flatly in place, interference fit is formed between the transparent upper cover and the elastic piece, and the gap can be sealed without additional glue dispensing and a good waterproof effect is achieved.
The invention solves the problem of the gap between the TP glass and the metal frame, and the elastic piece is used for completely blocking the gap. Compare in traditional point and glue the scheme equipment simply, the uniformity is very high, has still saved the space of assembly. The invention can also be extended to wearable products and products assembled by applying a glass cover plate and a metal shell.
While the invention has been shown and described with reference to certain embodiments, those skilled in the art will understand that: various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
