Description

Gluing structure

Technical Field

The present disclosure relates to a bonding structure.

Background

With the wider and wider use of touch screens, touch screens can be applied in a variety of environments, such as places or locations where high demands on safety, aesthetics and durability are not compromised. Such as a hospital, school, kindergarten, or exhibition hall.

However, in the case of a commercially available product including a touch screen, the edge of the touch screen is often in direct contact with the housing, so that the touch screen is easily damaged or even broken due to collision or dropping. Some products have a filling plastic material between the housing and the touch screen, but the filling material has a rugged appearance and is quite unattractive.

Therefore, how to provide a stable, reliable and beautiful glued structure is one of the problems to be solved by the research and development resources in the industry.

Disclosure of Invention

Accordingly, an objective of the present disclosure is to provide a bonding structure for solving the above-mentioned problems.

In order to achieve the above objective, according to one embodiment of the present disclosure, a bonding structure includes a first object, a second object, and a sealant layer. The first object is provided with a groove. The groove is provided with a bottom surface and an inner wall surface. The second object is accommodated in the groove and provided with a first side surface opposite to the inner wall surface. The groove is formed between the inner wall surface and the first side surface. The sealant layer is filled in the groove. The sealant layer is in full contact with the edge of the inner wall surface away from the bottom surface and the edge of the first side surface away from the bottom surface.

In one or more embodiments of the present disclosure, the adhesive structure further comprises an adhesive layer. The adhesive layer is adhered between the second object and the bottom surface.

In one or more embodiments of the present disclosure, the sealant layer contacts the adhesive layer.

In one or more embodiments of the present disclosure, the sealant has a concave cambered surface. The concave cambered surface is positioned at one side of the sealant layer far away from the bottom surface.

In one or more embodiments of the present disclosure, the first object further has a first top surface. The first top surface is connected with the inner wall surface. The first top surface is connected with the concave cambered surface.

In one or more embodiments of the present disclosure, the second object further has a second top surface and a second side surface. The second side surface is connected between the second top surface and the first side surface. The second side surface is connected with the concave cambered surface.

In one or more embodiments of the present disclosure, the height of the inner wall surface relative to the bottom surface is different from the height of the first side surface relative to the bottom surface.

In one or more embodiments of the present disclosure, the sealant layer is an annular structure.

In one or more embodiments of the present disclosure, the sealant layer has a fixed width.

In one or more embodiments of the present disclosure, the first object is a plastic housing and the second object is a glass panel.

In summary, since the bonding structure of the present disclosure includes the sealant layer having the concave arc surface, and the sealant layer can completely contact the edge of the inner wall surface of the first object far away from the bottom surface and the edge of the first side surface of the second object far away from the bottom surface, the sealant layer can form a complete circle of beautiful art designing seams. The sealant layer can stably fix the second object in the groove of the first object while achieving the effects of attractive appearance and water resistance.

The above description is merely illustrative of the problems to be solved by the present disclosure, the technical means for solving the problems, the effects thereof and the like, and the specific details of the present disclosure are set forth in the following description and related drawings.

Detailed Description

Various embodiments of the present disclosure are disclosed in the following figures, in which numerous practical details are set forth in the following description for purposes of clarity. However, it should be understood that these practical details are not to be used to limit the present disclosure. That is, in some embodiments of the present disclosure, these practical details are not necessary. In addition, for simplicity of illustration, some well-known structures and elements are shown in the drawings in a simplified schematic manner. The same reference numbers will be used throughout the drawings to refer to the same or like elements.

Spatially relative terms (e.g., "below," "beneath," "under," "above," "over," etc. Guan Cihui) may be used herein to describe briefly a relationship of an element or feature to another element or feature as illustrated. In use or operation, these spatially relative terms encompass different orientations of the device in addition to the orientation depicted in the figures. Furthermore, these devices may be rotated (90 degrees or other angles) and spatially relative descriptors used herein interpreted accordingly. In addition, the term "made of …" may mean "comprising" or "consisting of …".

Please refer to fig. 1 and fig. 2 simultaneously. Fig. 1 is a perspective view illustrating a gluing structure S according to an embodiment of the disclosure. Fig. 2 is an exploded view showing a bonding structure S according to an embodiment of the disclosure. In the present embodiment, the bonding structure S includes a first object 100, a second object 200, and a sealant layer 300. The first article 100 has a recess 108. The second object 200 is received in the recess 108. One side of the sealant layer 300 is connected to the first object 100, and the other side is connected to the second object 200 in a surrounding manner. The sealant layer 300 provides waterproof, anti-collision and aesthetic effects.

It should be noted that the gluing structure S of the present disclosure can be applied to various devices. For example, the first object 100 may be square, circular, or any suitable shape. The second object 200 may be of any suitable shape, in addition to being sized to be received in the recess 108 of the first object. The sealant layer 300 is formed by injecting glue between the first object 100 and the second object 200 and then drying and solidifying. That is, the sealant layer 300 may have any shape and may have various dimensions according to the distance between the first object 100 and the second object 200 and the depth of the groove 108.

Please refer to fig. 3 and fig. 4 simultaneously. Fig. 3 is a partial top view illustrating the glued structure S in fig. 1. Fig. 4 is a partial top view showing a part of elements of the glued structure S in fig. 1. Since the glue structure S in fig. 4 has not been filled with the sealant layer 300, it can be clearly observed that the glue structure S has the grooves 500. In the present embodiment, the trench 500 is formed between the first object 100 and the second object 200. In this embodiment, glue is injected into the groove 500 (as shown in fig. 4), and the glue dries and shrinks to form the sealant layer 300 (as shown in fig. 3).

In some embodiments, since the groove 500 has a fixed width on either side of the second object 200, the sealant layer 300 filled in the groove 500 naturally also has a fixed width on either side of the second object 200. Accordingly, the sealant 300 is formed in a ring-shaped structure having a fixed width. Since the sealant 300 is formed by injecting glue, the first object 100 and the second object 200 on both sides are tightly adhered, so that the first object 100 and the second object 200 can be better buffered against collision in addition to more stable adhesion.

In some embodiments, the sealant layer 300 may be a different color depending on the needs. In some embodiments, the color of the sealant layer 300 is substantially the same as the color of the glue forming the sealant layer 300, for example: transparent, milky white, black, or other suitable color.

Please refer to fig. 5A. Fig. 5A is a partial cross-sectional view showing the glued structure S of fig. 1 along line 5-5. In this embodiment, the glue structure S further comprises a glue layer 400. The first article 100 has a bottom surface 102, an inner wall surface 104, and a first top surface 106. The second object 200 has a first side 202, a second side 204, and a second top 206. The sealant layer 300 has a concave cambered surface 302. The inner wall surface 104 faces the first side surface 202. A portion of the inner wall surface 104, the first side surface 202, and the bottom surface 102 form a channel 500 (shown in fig. 4). The sealant layer 300 is filled between the inner wall 104 and the first side 202. The sealant layer 300 fully contacts the edge of the inner wall surface 104 remote from the bottom surface 102 and the edge of the first side 202 remote from the bottom surface 102. In other words, the two ends of the concave arc surface 302 are respectively connected to the edge of the inner wall surface 104 away from the bottom surface 102 and the edge of the first side surface 202 away from the bottom surface 102. The concave cambered surface 302 is concavely contracted toward the bottom surface 102 to have a curvature. Accordingly, the concave arc surface 302 forms an art designing seam, so that the connection between the first object 100 and the second object 200 is more attractive.

In some embodiments, the adhesive layer 400 is configured to adhesively secure the second object 200 to the bottom surface 102 of the first object 100. The adhesive layer 400 may be any suitable adhesive material, such as double sided adhesive, quick drying adhesive, etc., and the disclosure is not intended to be limited to the material of the adhesive layer 400.

As can be clearly seen in fig. 5A and 5B, in the present embodiment, the sealant layer 300 contacts the adhesive layer 400, thereby providing a better waterproof effect.

In other embodiments, the sealant layer 300 may not contact the adhesive layer 400, possibly because of the deeper depth of the grooves 500, cost considerations, or the nature of the glue forming the sealant layer 300.

It should be noted that in some embodiments, the sealant layer 300 may be dried at room temperature. The sealant layer 300 forms a concave arc surface 302 on the side away from the bottom surface 102 after drying and shrinking. In order for the concave cambered surface 302 to be smooth and beautiful, the glue forming the sealant layer 300 needs to have high fluidity, and thus the viscosity of the glue is low. In some embodiments, the viscosity of the glue forming the sealant layer 300 is in the range of 15 Pa-s to 25 Pa-s.

In some embodiments, the material of the sealant layer 300 has high temperature resistance, so the disclosure is applicable to electronic devices that generate high temperatures. Acceptable temperatures (temperature resistance) for the sealant layer 300 are in the range of about-60 degrees celsius to about 260 degrees celsius.

In some embodiments, the thickness of the sealant layer 300 relative to the concave cambered surface 302 is in the range of about 3 millimeters to about 5 millimeters.

In some embodiments, the sealing glue layer 300 is formed by injecting glue into the groove 500, so that the gap between the first object 100 and the second object 200 can be completely filled, and a better waterproof effect can be achieved.

In some embodiments, the inner wall surface 104 and the first side surface 202 may have different heights relative to the bottom surface 102. In some embodiments, the height of the inner wall surface 104 relative to the bottom surface 102 is greater than the height of the first side surface 202 relative to the bottom surface 102. In other embodiments, the height of the inner wall surface 104 relative to the bottom surface 102 is less than the height of the first side surface 202 relative to the bottom surface 102. In the present embodiment, regardless of which of the inner wall surface 104 and the first side surface 202 is higher relative to the bottom surface 102, the sealant layer 300 completely contacts the edge of the inner wall surface 104 away from the bottom surface 102 and the edge of the first side surface 202 away from the bottom surface 102. In other words, in the present embodiment, both ends of the concave cambered surface 302 may have different heights with respect to the bottom surface 102.

Please continue to refer to fig. 5A. In this embodiment, the sealant layer 300 is connected to the edge of the second side 204. In other words, the concave arc surface 302 is connected between the first side 202 and the second side 204 near an end of the second object 200. The second side 204 is connected between the first side 202 and the second top 206. The second side 204 is chamfered (also referred to as chamfer). The second side 204 is configured to make the edge of the second object 200 smoother, so that the sharp edge is not easy to scratch the user, and the step of dispensing the sealant 300 is easier to perform. In addition, the second side 204 may form an art-designing seam with the concave arc surface 302, so that the connection between the first object 100 and the second object 200 is more attractive.

Please continue to refer to fig. 5A. In this embodiment, the first object 100 further has a first top surface 106. The first top surface 106 is connected to the inner wall surface 104. The sealant layer 300 is coupled to the first top surface 106. In other words, an end of the concave arc surface 302 that is adjacent to the inner wall surface 104 is connected at an interface between the inner wall surface 104 and the first top surface 106.

Please continue to refer to fig. 5A. In some embodiments, the first top surface 106, the concave curved surface 302, the second side surface 204, and the second top surface 206 are sequentially connected to form a portion of the appearance surface of the glued structure S. The glued structure S has the concave arc surface 302 and the second side 204, which can be used as an art designing seam, so that the connection between the first object 100 and the second object 200 is more attractive.

Please refer to fig. 5B. Fig. 5B is a partial cross-sectional view illustrating a glued structure S according to other embodiments of the disclosure. In other embodiments, the first top surface 106, the concave curved surface 302, and the second top surface 206 are sequentially connected to form a portion of the appearance surface of the glued structure S. The glued structure S has the concave arc surface 302, which can be used as an art designing seam, so that the connection between the first object 100 and the second object 200 is more attractive.

In the present embodiment, the first object 100 is a plastic housing, and the second object 200 is a glass panel. For example, the second object 200 may be a glass substrate of a touch screen. It should be noted that the high-fluidity glue forming the sealant layer 300 may be used to adhere to any suitable material surface, and the disclosure is not intended to be limited to the material of the first object 100 and the second object 200. Preferably, the first object 100 and the second object 200 bonded by the sealant layer 300 are made of plastic, glass or metal, and the sealant layer 300 can be better bonded between the first object 100 and the second object 200.

As is apparent from the above description of the embodiments of the present disclosure, since the adhesive structure of the present disclosure includes the sealant layer, the sealant layer completely contacts the edge of the inner wall surface away from the bottom surface and the edge of the first side surface away from the bottom surface, the effects of waterproofing, buffering external impacts and firmly adhering can be provided. In addition, as the sealing glue layer is provided with the concave cambered surface, an art designing seam can be formed, so that the appearance surface of the glued structure is more attractive.

The foregoing outlines features of several embodiments so that those skilled in the art may better understand the aspects of the present disclosure. Those skilled in the art will appreciate that they can readily use the above-described embodiments as a basis for designing or modifying other changes to carry out the same purposes and/or achieve the same advantages of the embodiments introduced herein without departing from the spirit and scope of the present disclosure. The foregoing is to be understood as illustrative examples of the disclosure, the scope of which is to be determined by the claims.
