Technical Field
[0001] The utility model relates to a waterproof and sealed backlight rubber strip. Background Art
[0002] At present, in electronic devices, there is often a problem of insufficient sealing at the connection between the backlight module and the display module. Due to the complex and changeable use environment of electronic devices, such as humidity, dust, etc., these factors may damage the backlight module, affecting the normal operation and service life of the device. Therefore, it is particularly important to design a waterproof and sealed backlight rubber strip that can effectively solve the sealing problem. Summary of the Utility Model
[0003] Therefore, in view of the above problems, the utility model provides a waterproof and sealed backlight rubber strip.
[0004] To achieve the above object, the utility model adopts the following technical solutions: A waterproof and sealed backlight rubber strip is provided at the edge between the display module and the backlight module, including a rubber strip body in the shape of a square frame. The rubber strip includes a flat mounting portion, and the upper surface of the mounting portion is provided with a left suspended portion extending obliquely upward to the left and in a suspended state and a right suspended portion extending obliquely upward to the right and in a suspended state in the middle.
[0005] Further improvement, both the left suspended portion and the right suspended portion are arc-shaped and symmetrically arranged.
[0006] Further improvement, at least one first arc-shaped convex strip with a hollow inner cavity is respectively provided on one side of the left suspended portion and the right suspended portion facing the mounting portion.
[0007] Further improvement, a plurality of second arc-shaped convex strips with hollow inner cavities are arranged at intervals from left to right on the lower surface of the mounting portion.
[0008] Further improvement, a plurality of card slots for fixing positions are provided on the inner edge of the mounting portion.
[0009] Further improvement, a waterproof and anti-fouling coating is coated on the surface of the rubber strip body.
[0010] By adopting the foregoing technical solution, the beneficial effects of the present utility model are as follows: The rubber strip of the present utility model has a left suspended part and a right suspended part provided on the installation part, so that the rubber strip has better flexibility and adaptability during the assembly process, ensuring the sealing effect, and can effectively prevent water and dust from entering between the display module and the backlight module, thereby improving the waterproof and dustproof performance of the product. At the same time, the arc-shaped left suspended part and right suspended part have relatively small rigidity at the beginning of extrusion. However, as the extrusion progresses, their rigidity will be greatly improved. Combined with the support provided by the first arc-shaped convex strip, it is not easy to produce fatigue, further improving the sealing effect of the sealing strip and extending its service life; further, the setting of the second arc-shaped convex strip can increase the sealing degree of the rubber strip while enhancing the structural strength of the installation part. Further, the card slot is used to cooperate with the edge of the backlight module to ensure that the rubber strip will not be displaced during the assembly process; further, the waterproof and antifouling coating can effectively prevent liquids and dirt from adhering to the surface of the rubber strip, extending the service life of the product.

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Refer to Figures 1-3, this embodiment provides a waterproof and sealed backlight rubber strip, which is arranged at the edge between the display module and the backlight module. It includes a rubber strip body in the shape of a square frame. The rubber strip includes a flat mounting part 1. On the upper surface of the mounting part 1, a left suspended part 2 extending obliquely upward to the left and in a suspended state and a right suspended part 3 extending obliquely upward to the right and in a suspended state are provided in the middle. Both the left suspended part 2 and the right suspended part 3 are arc-shaped and symmetrically arranged. On the side of the left suspended part 2 and the right suspended part 3 facing the mounting part 1, at least one first arc-shaped convex strip 4 with a hollow inner cavity is provided respectively. In this embodiment, two first arc-shaped convex strips 4 are provided on each side, and the diameter of the first arc-shaped convex strip 4 located inside is smaller than the diameter of the first arc-shaped convex strip 4 located outside. The settings of the left suspended part 2 and the right suspended part 3 make the rubber strip have better flexibility and adaptability during the assembly process, ensure the sealing effect between it and the display module, can effectively prevent water and dust from entering between the display module and the backlight module, thereby improving the waterproof and dustproof performance of the product. Its rigidity is relatively small at the beginning of extrusion, but as the extrusion progresses, its rigidity will be greatly improved. Combined with the support given by the first arc-shaped convex strip 4, it is not easy to produce fatigue, further improving the sealing effect of the sealing strip and increasing its service life.
[0018] In this embodiment, in order to achieve the sealing degree between the rubber strip and the backlight module and at the same time enhance the structural strength of the mounting part 1, a plurality of second arc-shaped convex strips 5 with hollow inner cavities are arranged at intervals from left to right on the lower surface of the mounting part 1. A plurality of card slots 6 for fixing positions are arranged on the inner edge of the mounting part 1 to cooperate with the edge of the backlight module to ensure that the rubber strip will not be displaced during the assembly process.
[0019] In this embodiment, the surface of the rubber strip body is coated with a waterproof and anti-fouling coating to prevent liquids and dirt from adhering to the surface of the rubber strip, extending the service life of the product.
[0020] Although the present invention is specifically shown and described in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them fall within the protection scope of the present invention.
