Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The inventors of the present application have found, through long-term research: in the related art, the housing of the electronic device is mostly made of a metal material, and the cover plate is mostly made of a glass material; accordingly, in the whole assembly process of the electronic device, the connection between the glass cover plate and the metal shell is generally realized by a dispensing manner. Furthermore, in order to ensure the overall adhesive strength of the electronic device and the indexes of dust and water resistance at the IP68 level, a certain adhesive dispensing width is generally reserved on the frame part of the electronic device; in the related art, the dispensing width is more than 0.5 mm. On one hand, the width of the black edge of the whole machine is increased, so that the appearance effect of the electronic equipment is influenced; on the other hand, the frame is prevented from further shrinking, so that the screen occupation ratio of the electronic equipment is limited to a certain extent. For the case made of the same glass material, no effective technical scheme is provided by all manufacturers at present to realize the connection between the glass cover plate and the glass case and to take the above indexes and the design requirements of the narrow frame into consideration. To this end, the present application provides the following examples.

Referring to fig. 1, fig. 1 is a schematic cross-sectional structure diagram of a first embodiment of a housing assembly provided in the present application.

The housing assembly 10 of the present embodiment includes a glass housing 11 and a glass cover 12. The glass housing 11 may be a rectangular parallelepiped (uncovered) box-shaped member in external configuration, and as shown in fig. 1 and 2, the glass cover plate 12 may be a flat plate-like square member in external configuration. In other embodiments, the glass housing 11 may also be a cylindrical (uncovered) barrel-like member in profile, and the glass cover plate 12 may be a circular member in profile similar to a flat plate. Further, the glass cover plate 12 and the glass housing 11 are matched in shape and size, so that the glass cover plate 12 can be covered on the glass housing 11 and form the accommodating space 13. The accommodating space 13 can be used for accommodating electronic components such as a display panel, a processor, a camera module, and a battery.

The glass housing 11 includes a bottom wall 111 and a side wall 112 standing on the bottom wall 111, and the side wall 112 extends toward a side away from the bottom wall 111. The included angle theta between the side wall 112 and the bottom wall 111 can be within the range of 90 degrees to 120 degrees, so that the volume of the glass shell 11 can be increased on one hand, and the roundness of the glass shell 11 on the outer shape structure can be increased on the other hand. In the present embodiment, the side wall 112 and the bottom wall 111 are integrally formed, and are perpendicular to each other. In other embodiments, the side wall 112 and the bottom wall 111 may be two separate structural members, and the two may be connected by glue, welding, or the like. Further, since the sidewall 112 has a certain thickness, the connection between the sidewall 112 and the bottom wall 111 forms an inner corner close to the accommodating space 13 and an outer corner far away from the accommodating space 13. Wherein, above-mentioned interior angle and exterior angle all carry out radius angle or chamfer angle and handle, can increase the structural strength between lateral wall 112 and the diapire 111 on the one hand, for example avoid the stress concentration that arouses because of structural closed angle to increase glass housing 11's reliability, on the other hand can increase glass housing 11 the degree of roundness on the appearance structure, thereby increase the experience degree that the consumer gripped housing assembly 10.

The glass cover plate 12 includes a viewing area 121 and a welding area 122 disposed adjacently, the welding area 122 is located at an edge of the glass cover plate 12, and the welding area 122 is connected with the sidewall 112 by the glass solder 14, so that the glass cover plate 12 is connected with the glass housing 11 by welding. The present embodiment is described by taking the example that the bonding pad 122 surrounds the visible area 121. Based on the above description, the glass housing 11 may be a rectangular parallelepiped (uncovered) box-shaped member in the shape structure, and the glass cover plate 12 and the glass housing 11 are matched in the shape structure and the size dimension. At this time, the glass housing 11 has four sequentially connected sidewalls 112 arranged in a ring shape, as shown in fig. 2. Accordingly, the visible area 121 may be simply regarded as a rectangular area having a certain area (similar to a soccer field in a playground), and the welding area 122 may be simply regarded as a ring area having a certain width (similar to a track surrounding a soccer field in a playground), as shown in fig. 1 and 3. That is, the welding area 122 may be four portions, which are respectively adjacent to four sides of the visible area 121, so that the four portions of the welding area 122 can be connected to the four sidewalls 112 of the glass housing 11 by soldering using glass solder. In other embodiments, the welding regions 122 may be any one, two, or three of the above four portions, and the welding regions 122 are respectively connected to the corresponding sidewalls 112 by welding through a glass solder, and the rest are bonded by a sealant. Of course, in other embodiments, the connection between the glass cover plate 12 and the glass housing 11 may also be completely realized by the sealant.

Optionally, the glass housing 11 and the glass cover plate 12 are made of silica-alumina glass, and the glass filler metal 14 is made of silica-alumina glass or soda-lime glass. After the surface of the special glass is subjected to surface strengthening treatment, the surface compressive stress can reach 880MPa, the impact strength is improved by 5-8 times compared with that of common glass, the wear resistance is obviously improved, and the Vickers hardness can reach 1800-2400 HV.

Note that, since the thickness of the glass filler metal 14 before and after welding is thin, it is not explicitly identified in some drawings of the embodiments of the present application.

The inventors of the present application further found, through long-term research: the cover plate of the related art is generally embedded in the shell, and the end surface of the cover plate is connected with the inner wall of the shell in a gluing way through sealant; the glass cover plate 12 of the present embodiment is covered on the glass housing 11, and the lower surface of the glass cover plate 12 is connected to the top surface of the sidewall 112 of the glass housing 11 by welding via the glass solder 14, as shown in fig. 1. Under the requirement of the same packaging performance, the welding width of the embodiment is only 0.2mm for welding through the glass solder 14; and the glue joint width of more than 0.5mm is needed when glue joint is carried out through the sealant. In other words, in the present embodiment, the glass solder 14 is used to weld the glass cover plate 12 and the glass housing 11, so that the housing assembly 10 has more excellent packaging performance, such as structural strength, dust-proof and water-proof performance, corrosion resistance, and the like; the effective area of the viewing area 121 may also be increased.

Alternatively, a receiving groove 1121 may be formed on the side of the side wall 112 where the welding region 122 is welded, as shown in fig. 4, the receiving groove 1121 is used for receiving the glass solder 14, so as to prevent the glass solder 14 from overflowing due to excessive fluidity, insufficient surface tension and the like during the welding process (after melting), thereby increasing the reliability of the welding process. Wherein, in order to ensure the welding width between the welding region 122 and the side wall 112, the width of the material accommodating groove 1121 may be 0.2-0.3 mm. Further, in order to secure the structural strength of the sidewall 112, the width thereof may be 1.5-1.6 mm. In order to ensure the effective area of the visible area 121, the accommodating trough 1121 may be further away from the accommodating space 13; in order to protect the welding area, the accommodating groove 1121 may be closer to the accommodating space 13. The present embodiment is described by taking the material accommodating groove 1121 as an example located in the middle area of the side wall 112, as shown in fig. 4, to comprehensively balance the requirements in various aspects. In other embodiments, the surface of the sidewall 112 welded to the welding region 122, and the surface of the welding region 122 welded to the sidewall 112 may be roughened by surface etching, sanding, etc. to prevent the glass solder 14 from overflowing after melting, and to increase the effective contact area of the above welding, so as to increase the welding strength between the welding region 122 and the sidewall 112, and further increase the reliability of the case assembly 10.

Alternatively, after the welded connection between the welding region 122 and the side wall 112 is made by the glass filler metal 14, the end surface of the glass cover plate 12 is flush with or recessed in the outer surface of the glass housing 11. In the present embodiment, the end surface of the glass cover 12 is flush with the outer surface of the glass housing 11, as shown in fig. 1. Further, one surface of the glass cover plate 12 away from the glass housing 11 and the end surface thereof are polished to make the edge of the glass cover plate 12 have a certain radian (for example, 2.5D), so that the glass cover plate 12 can be like an overflowing water droplet, and the glass cover plate 12 has more visual tension, thereby increasing the visual effect of the housing assembly 10, and also increasing the hand feeling of holding the housing assembly 10. In other embodiments, the surface of the glass cover plate 12 away from the glass housing 11 and the end surface thereof may also be directly rounded or chamfered, which may also provide the housing assembly 10 with good visual effect and hand-holding feeling.

Referring to fig. 5, fig. 5 is a schematic cross-sectional structure diagram of a second embodiment of the housing assembly provided by the present application.

In this embodiment, the sidewall 112 includes a first sub-sidewall 1122 and a second sub-sidewall 1123 arranged in a step-like manner. The first sub-side wall section 1122 is close to the bottom wall 111, and the second sub-side wall section 1123 stands on a surface of the first sub-side wall section 1122 away from the bottom wall 111, and forms a first step surface 1124 with the first sub-side wall section 1122. The welding region 122 and the first step surface 1124 are welded by the glass filler metal 14, so that the glass cover plate 12 and the glass housing 11 are welded.

Optionally, the first step surface 1124 is formed with a receiving groove 1121, as shown in fig. 6, so as to receive the glass filler metal 14, thereby preventing the glass filler metal 14 from overflowing after melting. Wherein, since the width of the material accommodating groove 1121 may be 0.2-0.3mm, the width of the first step surface 1124 (i.e. the overlapping width) may be slightly larger than the width of the material accommodating groove 1121, for example, the overlapping width is 0.3-0.4 mm; moreover, the material accommodating groove 1121 may be directly contacted with a surface of the second sub-side wall segment 1123 close to the accommodating space 13, as shown in fig. 6, so that the welding width can be ensured, and the effective area of the visible area 121 can be increased. In other embodiments, the first stepped surface 1124 and the surface of the welding region 122 adjacent to the first stepped surface 1124 may be rough, which can prevent the glass filler metal 14 from overflowing after melting and can increase the effective contact area of the welding.

In this embodiment, when the glass cover plate 12 is covered on the glass housing 11, the glass cover plate 12 is partially or completely embedded in the glass housing 11, as shown in fig. 5; at this time, a gap is formed between the end surface of the glass cover plate 12 and the second sub-sidewall 1123, and the gap can facilitate the placement of the glass cover plate 12 on the one hand and the adaptation of the glass cover plate 12 of the welding region 122 to the thermal expansion during the welding process on the other hand. Theoretically, the width of the gap can approach zero infinitely; this embodiment will be described by taking an example in which the width of the gap is 0.15mm or less. Further, after the solder connection between the land 122 and the first step surface 1124 is made by the glass solder 14, the gap may be filled with the sealant 15. On one hand, the sealant 15 can be used for realizing the glue joint between the end face of the glass cover plate 12 and the second sub-side wall section 1123, so that a composite connection of one-step welding and one-step glue joint is formed between the glass cover plate 12 and the glass shell 11, and the structural strength, the dustproof and waterproof performance and the like between the glass cover plate 12 and the glass shell 11 are further improved; the sealant 15 can also play a role in buffering impact between the glass cover plate 12 and the glass housing 11, so as to reduce the risk of breakage of the glass cover plate 12 and/or the glass housing 11, thereby increasing the reliability of the housing assembly 10.

Alternatively, after the welded connection between the welding area 122 and the first stepped surface 1124 is made by the glass filler metal 14, the glass cover plate 12 is flush with or protrudes from the glass housing 11. The present embodiment is described by taking an example in which the glass cover 12 is flush with the glass housing 11, as shown in fig. 5. Generally, the thickness of the glass cover plate 12 is less than or equal to 2mm, which is inconvenient for surface strengthening treatment of the end face of the glass cover plate 12; the overall height of the glass shell 11 can be 6-8mm, and the surface strength treatment can be conveniently carried out on the outer surface of the glass shell 11. At this time, since the glass cover plate 12 is surrounded by the second sub-sidewall section 1123, the glass housing 11 can protect the glass cover plate 12 to some extent, thereby increasing the reliability of the housing assembly 10. Wherein, in order to ensure the structural strength of the second sub-sidewall segment 1123, the width thereof may be 1.5-1.6 mm. Further, the outer surface of the second sub-sidewall 1123 away from the receiving space 13 and the top surface flush with the glass cover plate 12 are polished to make the edge of the glass housing 11 have a certain curvature (e.g. 2.5D), which can increase the visual effect of the housing assembly 10 and the grip feeling of the housing assembly 10. In other embodiments, the outer surface of the second sub-sidewall 1123 away from the receiving space 13 and the top surface flush with the glass cover 12 may be rounded or squared, which may also provide the housing assembly 10 with good visual effect and hand-holding feeling.

Further, other structures of the present embodiment are the same as or similar to those of the above embodiments, and are not described herein again.

Referring to fig. 7, fig. 7 is a schematic cross-sectional structure diagram of a third embodiment of the housing assembly provided by the present application.

In this embodiment, the bonding pad 122 includes a first sub-bonding pad 1221 and a second sub-bonding pad 1222 arranged in a step shape. The first sub-pad 1221 is close to the display area 121, and forms a second step 1223 with the second sub-pad 1222. The first sub-welding area 1221 and the first step surface 1124 are welded and connected by glass solder 14, and the second step surface 1223 and the second sub-side wall section 1123 are welded and connected by glass solder 14, so that the glass cover plate 12 and the glass housing 11 are welded and connected. In this way, two welding connections can be formed between the glass cover plate 12 and the glass housing 11, so as to further increase the structural strength, the dust-proof and water-proof performance, and the like between the glass cover plate 12 and the glass housing 11, and further increase the reliability of the housing assembly 10.

Optionally, a material containing groove 1121 is formed on one side of the second sub-side wall section 1123 welded to the second step surface 1223 and/or the first step surface 1124 so as to contain the glass filler metal 14, thereby preventing the glass filler metal 14 from overflowing after being melted. In other embodiments, the first step surface 1124, a surface of the first sub-land 1221 adjacent to the first step surface 1124, the second step surface 1223, and a surface of the second sub-sidewall segment 1123 adjacent to the second step surface 1223 may also be rough surfaces, which can prevent the glass filler metal 14 from overflowing after melting and can increase the effective contact area of the above welding. Of course, in other embodiments, the material receiving groove 1121 may be formed at the same time and the rough surface may be formed, so as to achieve the above-mentioned effects.

Further, other structures of this embodiment are the same as or similar to those of any of the above embodiments, and are not repeated herein.

Referring to fig. 8, fig. 8 is a schematic cross-sectional structure view of a fourth embodiment of the housing assembly provided in the present application.

In this embodiment, the sidewall 112 further includes a third sub-sidewall segment 1125. The third sub-sidewall section 1125 stands on the second sub-sidewall section 1123 at a side away from the first sub-sidewall section 1122, and forms a third step 1126 with the second sub-sidewall section 1123. The first sub-welding area 1221 and the first step surface 1124 are welded and connected by glass solder 14, and the second step surface 1223 and the third step surface 1126 are welded and connected by glass solder 14, so that the glass cover plate 12 and the glass housing 11 are welded and connected.

Optionally, the first step surface 1124 and/or the third step surface 1126 are provided with a receiving groove 1121 to receive the glass filler metal 14, thereby preventing the glass filler metal 14 from overflowing after melting. In other embodiments, the first step surface 1124, the surface of the first sub-land 1221 adjacent to the first step surface 1124, the second step surface 1223, and the third step surface 1126 may also be rough surfaces, which can prevent the glass filler metal 14 from overflowing after melting and can increase the effective contact area of the above welding. Of course, in other embodiments, the material receiving groove 1121 may be formed at the same time and the rough surface may be formed, so as to achieve the above-mentioned effects.
