Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a highly sealed liquid crystal display for use on two-wheeled vehicles. Background Technology

[0002] An LCD display is an instrument that uses liquid crystal display technology to display information such as numbers, text, and images. Liquid crystal material is filled between two pieces of glass to form a liquid crystal layer. There is a polarization plate on each side of the liquid crystal layer with mutually perpendicular polarization directions. There is also a backlight system that provides backlight and color filters for generating different colors of light.

[0003] LCD displays have been applied in many fields, with a wide range of applications in two-wheeled vehicles. Patent number 202222664602.X discloses a sealing connection structure for an electric vehicle dashboard, which involves a sealing groove between the upper and lower inner housings, with a sealing ring installed inside. While this provides a certain level of sealing, the sealing level or effect achieved solely through the cooperation of the sealing ring and the mounting groove cannot meet the needs of special circumstances, such as heavy rain or continuous downpours. In such situations, the dashboard is constantly exposed to rainwater, making it prone to loss of seal. Therefore, products with good sealing performance for LCD screens are particularly needed. Utility Model Content

[0004] The main objective of this invention is to provide an embedded tuning meter that can effectively solve the problem of high sealing performance in LCD display meters in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a highly sealed liquid crystal display for use on a two-wheeled vehicle, comprising a screen body placed on the two-wheeled vehicle, the screen body comprising a front screen and a rear cover that covers the front screen, a first annular groove provided on the end face of the end where the front screen and the rear cover are fitted together, an annular protrusion provided on the front screen that cooperates with the first annular groove, the surface of the annular protrusion being coated with a layer of waterproof adhesive, a stepped groove provided on the outer wall of the rear cover, the stepped groove circling the rear cover, an extension piece provided on the outer wall of the front screen that cooperates with the stepped groove, and a sealing component for sealing the joint between the front screen and the rear cover inside the rear cover.

[0006] The sealing assembly is further configured such that: the sealing plate is shaped like a U-shape and is respectively attached to the inner walls of the front screen and the rear cover.

[0007] The sealing plate is further configured such that a second annular groove is provided on the outer wall of the sealing plate, and the second annular groove is filled with a rubber ring.

[0008] The device is further configured such that: a limiting ring is provided on the front screen and the rear cover, and the limiting ring is fitted to the inner wall of the sealing plate.

[0009] Further configuration: A layer of waterproof adhesive is applied to the stepped groove.

[0010] A further configuration is provided: an elastic layer is provided at both ends of the sealing plate.

[0011] Further configuration: the material of the elastic layer is rubber.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The unique connection method between the front screen and the back cover, combined with waterproof adhesive one and waterproof adhesive two, achieves a double seal. In addition, the unique design of the built-in sealing components creates a triple seal, thus ensuring a high overall sealing performance. Attached Figure Description

[0016] The following will refer to the appendix in the embodiments of this utility model. Figure 1-2 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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.

[0018] The front screen 101 and the rear cover 201 are fitted together. A first annular groove 102 is provided on the end face of the front screen 101 and the rear cover 201 at the fitting end. The first annular groove 102 is matched with an annular protrusion 301. A layer of waterproof adhesive 302 (silicone rubber) is applied to the surface of the annular protrusion 301. Waterproof adhesive 203 is the same as waterproof adhesive 302. The waterproof adhesive 203 is applied to the stepped groove 202. When the front screen 101 and the rear cover 201 are fitted together, two seals are formed by the stepped structure and the cooperation of the first annular groove 102 and the annular protrusion 301. The first seal is at the waterproof adhesive 203. In addition, the cooperation of the extension piece 103 and the stepped groove 202 creates a drop inside. When the product is placed on a two-wheeled vehicle, the front screen 101 faces upwards, so this step... The design of the groove 202, combined with the fit of the extension piece 103, provides excellent protection. To prevent rainwater from flowing back up, it needs to pass through the stepped groove 202 of a certain height. In addition, the cooperation of the first annular groove 102 and the annular protrusion 301, along with the waterproof adhesive 302 inside, further ensures the sealing performance. During assembly, a sealing component is also provided inside the rear cover 201 to seal the joint between the front screen 101 and the rear cover 201, forming a third seal. Using this U-shaped sealing plate 401, a limiting ring 104 is set inside the rear cover 201 and the front screen 101. When the sealing plate 401 is locked in the fixed position surrounded by the limiting ring 104, it facilitates the alignment of the front screen 101 and the rear cover 201 during installation. At the same time, the structure of the sealing plate 401 is used to seal the joint between the front screen 101 and the rear cover 201.

[0019] After being positioned, the second annular groove 403 on the outer wall of the sealing plate 401 is filled with a rubber ring 501. The rubber ring 501 has a certain elasticity. With the help of the elasticity of the rubber ring 501, it can provide a resistive sealing effect on the connection between the front screen 101 and the rear cover 201 when they are fitted together. Combined with the elastic rubber layer 402 set at both ends of the sealing plate 401, which is heat-fused to the sealing plate 401, after the front screen 101 and the rear cover 201 are closed, the sealing plate 401 can be squeezed, and the elastic layer 402 can provide a certain deformation distance. Thus, the overall product has a high sealing performance through the three-seal design.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
