Description

Technical Field

[0001] This utility model relates to the field of waterproof silicone buttons, and in particular to a silicone button structure with waterproof performance. Background Technology

[0002] As per customer requirements, a silicone button with an IP65 waterproof rating on both sides needs to be produced. Traditional silicone buttons only have waterproofing on the top, while the bottom side near the circuit board is not waterproof. In certain usage scenarios, such as coffee machine use, water vapor can easily leak from the bottom gaps of the silicone button into the interior, causing a short circuit and significantly shortening the button's lifespan.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a waterproof silicone button structure to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a silicone button structure with waterproof performance.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a waterproof silicone button structure, comprising a silicone button, a light guide film, and a flexible circuit stacked on top of each other, wherein a waterproof wall extending downwards is formed at the edge of the silicone button, and a glue-filling gap is provided between the waterproof wall and the flexible circuit, and the glue-filling gap is filled with waterproof glue.

[0006] A preferred technical solution is that the top side of the silicone button is provided with a plastic shell.

[0007] A preferred technical solution is that double-sided adhesive is provided between the silicone button and the light guide film.

[0008] A preferred technical solution is that the bottom side of the light guide film is provided with adhesive.

[0009] A preferred technical solution is that the bottom side of the flexible circuit is provided with waterproof PET.

[0010] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0011] This utility model proposes a waterproof silicone button structure. By setting a waterproof wall extending downwards at the edge of the silicone button and filling the gap between the waterproof wall and the flexible circuit with waterproof adhesive, a waterproof structure is formed. In addition, by setting a waterproof PET on the bottom side of the flexible circuit, the top and bottom sides of the silicone button can achieve the IP65 waterproof rating requirement, thereby meeting the usage requirements of special application scenarios.

[0014] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0015] Please see Figures 1-2 It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0016] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
