Description

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a waterproofing backing adhesive structure, especially a waterproofing backing adhesion for being adhered between the front cover and the display panel that prevents detachment of the waterproofing backing adhesive structure from the front cover or the display panel due to a bubble.
2. Description of the Related Art
There are two major methods of waterproof design for current electronic products. One is by using the installation of an O-type gasket. Though the O-type gasket has the advantage of reuse, it needs a larger space for installation, so it is not suitable for application in small lightweight electronic products. The other is by using a waterproof backing adhesive. A waterproof backing adhesive can be applied in small lightweight electronic products and can provide a good waterproofing effect as well; however, the following problems will occur while it is in use.
Please refer to FIG. 1, which is related to a waterproof backing adhesive structure whose technology has been previous disclosed. Usually in the assembly process of the electronic device 90, production workers will first remove the paper-film on the bottom surface 14a of the backing adhesive 1a, adhere it to the front cover 91 of the electronic device 90, and then remove the paper-film on the upper surface 12a, after which the workers press and glue the display panel 92 of the electronic device 90 to the upper surface 12a of the backing adhesive 1a to make it adhere to the backing adhesive 1a. However, in the process of adhering the backing adhesive 1a, and in the instance of adhering the backing adhesive 1a, if the process of adhesion is not smooth enough to fully expel all air from between the backing adhesive 1a and the front cover 91 or display panel 92, the unexpelled air will be captured between the backing adhesive 1a and the front cover 91 or display panel 92 and will form an bubble 95 (as shown in FIG. 2). Although the existence of the bubble 95 will not immediately affect the usage of the electronic device 90, the bubble 95 will gradually expand and contract under air pressure due to expansion when it is hot, shrinkage when it is cold, or other factors of the backing adhesive 1a, over a long period of use of the electronic device 90 (as shown with an arrow in the figure). Therefore, if the width of the backing adhesive 1a is not wide enough (especially for handheld devices such as mobile phones of small size—if the visible area of the display panel is to be expanded, the width of the backing adhesive needs to be shrunken), it could lead to a local opening between the backing adhesive 1a and the front cover 91 or display panel 92, form a channel for leakage, allow water vapor to easily seep into the leakage, and cause the failure of the backing adhesive, which does not meet the requirements and standards of waterproof and dustproof of the IP (Ingress Protection).
SUMMARY OF THE INVENTION
The main purpose of the present invention is to provide a waterproofing backing adhesion structure that prevents the formation of a gap between the backing adhesive main body and the display panel or the backing adhesive main body and the front cover due to the expansion of bubbles between the backing adhesive main body and the display panel or the backing adhesive main body and the front cover.

FIG. 4 is an illustration of the appearance of the waterproofing backing adhesive structure according to the first embodiment of the present invention; FIG. 5 is a lateral cutaway view drawing of the waterproofing backing adhesive structure attached between the front cover and the display panel according to the first embodiment of the present invention.
As shown in FIG. 4, in the first embodiment of the present invention, the waterproofing backing adhesive structure 1 of the present invention includes a backing adhesive main body 10, an adhesive material 20, a plurality of air chambers 30, and at least one paper-film 40. The backing adhesive main body 10 includes an upper surface 12, a bottom surface 14, and a plurality of ribs 16, wherein the plurality of ribs 16 are formed in a unitary piece and protrude slightly from the upper surface 12 and the bottom surface 14 of the backing adhesive main body 10. Due to the spacing of the plurality of ribs 16 or interweaving among each of the ribs 16, a plurality of air chambers 30 can be formed. In the first embodiment of the present invention, there are a total of four ribs 16; the ribs 16 are formed in pairs on the upper surface 12 and on the bottom surface 14 of the backing adhesive main body 10. Moreover, each of the ribs 16 is parallel to each other and is arranged such that it extends parallel to the length of the backing adhesive main body 10. The heights of the ribs 16 on the same surface are essentially the same, but the heights of each of the ribs 16 on different surfaces can be different; and the positions of the ribs on different surfaces can correspond to each other, or they can be otherwise arranged.
The adhesive material 20, which is attached to the backing adhesive main body 10, is used for adhering the backing adhesive main body 10 between the front cover 91 and the display panel 92. As shown in FIG. 4, in the first embodiment of the present invention, the adhesive material 20 is attached to the ribs 16; however, the present invention is not limited to this; it can be attached to the upper surface 12 or to the bottom surface 14 of the backing adhesive main body 10 between any ribs 16.

When the waterproofing backing adhesive structure 1 of the present invention is used, the plurality of paper-films 40 are to be removed from the backing adhesive main body 10. In the first embodiment of the present invention, the quantity of the paper-films 40 is one on the top and another on the bottom; however, the quantity of the paper-films 40 is not limited to this.
As shown in FIG. 5, in the first embodiment of the present invention, after the paper-film 40 is removed, the waterproofing backing adhesive structure of the present invention is to be adhered between the front cover 91 and the display panel 92 of the electronic device 90 with the adhesive material 20 on the ribs 16. After the adhesion, if an bubble 95 is formed between a partial section of one rib 16 of the two ribs 16 and the front cover 91 or the display panel 92, then due to the gradual expansion of the bubble 95, a gap appears in the same section of the ribs 16 and between the ribs 16 and the front cover 91 or the display panel 92. In this way, the air of the bubble 95 is able to be transferred to the nearby air chamber 30 (as shown with an arrow in FIG. 5) and will not form a large gap due to its having a complete horizontal opening between the waterproofing backing adhesive structure 1 and the front cover 91 or the display panel 92 such that water vapor can easily enter via the large gap, and cause the failure of the backing adhesive eventually, as stated in the prior art. In addition, because air in the bubble 95 enters the air chamber 30, the bubble 95 is prevented from continuously expanding to another rib 16 due to the airtight pressure, so as to maintain close adhesion between another rib 16 and the front cover 91 or the display panel 92 on the backing adhesive main body 10. Because of the close adhesion between another rib 16 and the front cover 91 or the display panel 92, the waterproofing backing adhesive structure 1 can continuously maintain the waterproofing function.
However, it can be noticed from the above description that once an bubble 95 develops on the same corresponding location (the odds of having another bubble at the same spot are very low) of the another rib 16 and expands as well and causes the failure of the rib 16, the problem of losing the waterproofing function of the waterproofing backing adhesive structure 1 can arise, as mentioned in the prior art. Therefore, the quantity of the ribs 16 installed in the backing adhesive main body 10 of the present invention, within a certain range of the width, is not limited to two, as shown in FIG. 4., more ribs 16 can be installed to reduce the odds of the aforementioned problem as long as the sufficient adhesion is remained.
Next, please refer to FIG. 6 and FIG. 7. FIG. 6 is an illustration of the appearance of the waterproofing backing adhesive structure according to the second embodiment of the present invention; FIG. 7 is a lateral cutaway perspective drawing of the waterproofing backing adhesive structure attached between the front cover and the display panel according to the second embodiment of the present invention.
As shown in FIG. 6, the second embodiment of the present invention differs from the first embodiment of the present invention in that the plurality of ribs 16 are installed in an interwoven fashion, and each of the air chambers 30 is formed in a square by the interwoven arrangement of the ribs 16. As shown in FIG. 7, similarly, in the second embodiment of the present invention, if an bubble 95 forms between a partial section of one of the ribs 16 and the front cover 91 or the display panel 92 and causes separation of the surface of the partial section of the rib 16 and the front cover 91 or the display panel 92 due to expansion, the air in the bubble 95 can leak into a nearby air chamber 30 to achieve a result similar to that aforementioned in the first embodiment. Because the waterproofing backing adhesive structure 1 in the second embodiment of the present invention has more ribs 16 with the adhesive material 20, it can provide stronger adhesion than that in the first embodiment.
Finally, please refer to FIG. 8 and FIG. 9. FIG. 8 is an illustration of the appearance of the waterproofing backing adhesive structure according to the third embodiment of the present invention. FIG. 9 is a lateral cutaway perspective drawing of the waterproofing backing adhesive structure attached between the front cover and the display panel according to the third embodiment of the present invention.
As shown in FIG. 8, the third embodiment of the present invention differs from the first embodiment and the second embodiment of the present invention in that in the backing adhesive main body 10, protruding ribs 16 are no longer used to form the plurality of air chambers 30; instead, the plurality of air chambers 30 are formed with inward concave sockets 18. In this third embodiment of the present invention, the plurality of sockets 18 are round in shape, and the method of arrangement is similar to that of a matrix board, with both horizontal and vertical distribution of straight lines, but it can also be arranged with staggered spacing. However, the shape and the distribution of the plurality of sockets 18 of the waterproofing backing adhesive structure 1 of the present invention are not limited to this. As shown in FIG. 8 and FIG. 9, in the third embodiment of the present invention, the waterproofing backing adhesive structure 1 is adhered between the front cover 91 and the display panel 92 with the adhesive material 20 of the upper surface 12 and the bottom surface 14 of the backing adhesive main body 10; if a bubble 95 develops between the backing adhesive main body 10 and the front cover 91 or the display panel 92 and expands to cause separation of one part of the backing adhesive main body 10 from the front cover 91 or the display panel 92, the air in the bubble 95 will be exhausted to a nearby air chamber 30, as aforementioned in each of the previous embodiments, to achieve a result similar to that mentioned above.
It is to be noted that the above embodiments are only for illustration of the preferred embodiments of the present invention. In order to avoid redundancies, not all possible combinations are recorded in detail. However, those skilled in the art should understand that any implementations of the above-mentioned principles can be modified as needed; any designs that can form air chambers 30 in the backing adhesive main body 10 can fall within the scope of the present invention. It is to be understood that the formations of air chambers 30 with ribs 16 and with sockets 18 are actually the same in concept. In other words, from the viewpoint of the upper surface of the ribs 16, the spaces between each of the ribs 16 can be considered as the sockets 18; on the other hand, from the viewpoint of the upper surface of the inner sockets 18, the structures surrounding the upper surface of the inner sockets 18 can be considered as each of the ribs 16. Thus, the two formations of the air chambers 30 in the embodiments share the same relative concept. Additionally, it is preferable to have each of the air chambers 30 independent and without connections, but it does not exclude the possibility of having local or nearby air chambers 30 connected.
It is noted that the above-mentioned embodiments are only for illustration. It is intended that the present invention cover modifications and variations of the present invention provided they fall within the scope of the following claims and their equivalents. Therefore, it will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
