Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] The following will be based on Figures 1 to 4 The technical solutions in the embodiments of this application will be described in detail below.

[0026] In this embodiment, a display device 1 includes a frame 10, a glass cover plate 20 and a display module 30 arranged in sequence. The side of the frame 10 facing the glass cover plate 20 is provided with a glue groove 11 for filling glue. The glass cover plate 20 is bonded to the frame 10 by the glue in the glue groove 11. The display module 30 is assembled on the frame 10 and the display module 30 presses the glass cover plate 20 toward the frame 10.

[0027] Specifically, this utility model provides a display device 1. In use, the display device 1 has a frame 10, a glass cover 20, and a display module 30 installed sequentially from front to back on the user-facing side. The frame 10 is a rectangular frame with a blank inner area, allowing the glass cover 20 and display module 30 to be exposed, enabling image information and displays to be presented to the user. The rectangular design of the frame 10 avoids obstructing image information. The glue groove 11 of the frame 10 is used to fill and hold glue. The glue groove 11 extends in a straight line, and its cross-sectional shape can be rectangular, trapezoidal, U-shaped, etc., without limitation. The display module 30 can be assembled onto the frame 10 by snap-fit ​​connection or bolt connection, facilitating disassembly and maintenance. These two connection methods ensure the firmness of the connection between the display module 30 and the frame 10, ensuring the compression effect of the display module 30 on the glass cover 20. This ensures that the glass cover 20 is subjected not only to the adhesive force of the glue but also to the squeezing and clamping force, making it more stable and less prone to falling off.

[0028] Therefore, the glass cover 20 is subjected to the combined effects of the adhesive force of the glue on the frame 10 and the squeezing force of the display module 30, with the squeezing force directed towards the frame 10. This forces the glue to spread outwards under the pressure of the glass cover 20, increasing the contact area between the glue and the glass cover 20. This results in a stronger adhesion and a longer fixation time for the glass cover 20. As time goes on, the adhesive strength gradually weakens and loses its fixing effect on the glass cover 20. The squeezing and clamping force of the display module 30 can then serve as a backup force to maintain the fixing effect of the glass cover 20, preventing it from falling off. This improves the user experience, extends the interval between repairs, reduces the frequency of repairs, and thus lowers the burden of repeated maintenance.

[0029] In some embodiments, the adhesive groove 11 is a groove with an opening facing the glass cover plate 20, and the number of grooves is multiple and they are spaced apart along the outer edge contour direction of the frame 10.

[0030] Specifically, the side of the frame 10 facing the glass cover plate 20 is provided with a plurality of adhesive grooves 11. The adhesive grooves 11 are recessed into the inside of the frame 10 along the thickness direction to form the aforementioned grooves. It can be understood that the opening of the groove faces the glass cover plate 20. Multiple grooves are provided along the edge of the frame 10, and the distance between adjacent grooves can be equal or unequal. This embodiment is not limited to this.

[0031] Therefore, the grooves can be set at reasonable intervals, and the multiple grooves are independent structural units. When the adhesive layer in one groove is at risk of deformation or cracking, it does not affect the adhesive layer in the other grooves. This maintains the adhesive fixation effect on the glass cover 20 and ensures the stability of the glass cover 20.

[0032] In some embodiments, the groove 11 is a recess with an opening facing the glass cover plate 20, and the groove extends along the outer edge contour of the frame 10 and closes at both ends.

[0033] Specifically, the groove is set on the outer edge of the frame 10 and is closed at both ends. Since the frame 10 is a rectangular frame, the planar shape of the groove is rectangular or square.

[0034] Therefore, the closed design of the glue groove 11 allows the outer edge of the frame 10 to be glued to the glass cover 20, thus increasing the bonding area of ​​the glass cover 20 and improving the firmness and reliability of the bonding, making the glass cover 20 less prone to loosening.

[0035] In some embodiments, the adhesive in the glue tank 11 is a waterproof neutral adhesive.

[0036] Specifically, the adhesive can be neutral curing silicone adhesive, neutral polyurethane adhesive, or MS polymer adhesive, etc.

[0037] Therefore, the adhesive is made of a waterproof material with good water tightness and a low water molecule permeability coefficient, effectively preventing moisture from penetrating the glass cover 20 or the display module 30. This provides appropriate moisture protection for both the display module 30 and the glass cover 20. Simultaneously, the waterproof neutral adhesive reduces or prevents moisture penetration, protecting the adhesive layer itself, slowing down its aging and extending its service life. Furthermore, the use of a neutral adhesive ensures that no acidic substances are generated during the curing process, preventing corrosion of the frame 10 or the glass cover 20.

[0038] In some embodiments, the display module 30 includes a housing 31, a sheet metal frame 32, and a liquid crystal screen 33. The sheet metal frame 32 is assembled inside the housing 31, and the liquid crystal screen 33 is embedded inside the sheet metal frame 32. The housing 31 is fixedly assembled with the frame 10, and the side of the housing 31 facing the frame 10 is an open structure. The sheet metal frame 32 presses the glass cover plate 20 through the open area of ​​the housing 31.

[0039] Specifically, the shape of the outer shell 31 roughly matches the shape of the frame 10. The edge of the open structure of the outer shell 31 is fixedly assembled with the frame 10. The fixed assembly method can be bolt connection, snap-fit ​​connection, etc. These connection methods are conventional technologies in the field and will not be described in detail here.

[0040] Specifically, the sheet metal frame 32 is assembled onto the outer casing 31 by means of bolts, screws, welding, or even integral molding, with the edge portion of the sheet metal frame 32 pressing against the glass cover plate 20. The LCD screen 33 is embedded in the sheet metal frame 32, adjacent to the glass cover plate 20, with a small gap between them.

[0041] Therefore, the LCD screen 33 is used to display image information, and the glass cover 20 provides protection for the LCD screen 33, preventing scratches and wear. The glass cover 20 also has high light transmittance, making it easy for people to view the image information of the LCD screen 33. The sheet metal frame 32 has good compressive strength, which can stably and well support the LCD screen 33. The design of the outer shell can also protect the LCD screen 33 and other internal equipment.

[0042] In some embodiments, the housing 31 has a frame 310 protruding in a direction away from the frame 10, and a circuit board is provided inside the frame 310. The circuit board is electrically connected to the LCD screen 33.

[0043] Specifically, the frame 310 is located on the side of the outer shell 31 away from the frame 10. The frame 310 protrudes outward relative to the outer shell 31. It can be understood that the internal space of the frame 310 is connected to the internal space of the outer shell 31, so that the circuit board inside the frame 310 and the LCD screen 33 inside the outer shell 31 can be electrically connected by wires.

[0044] Therefore, the circuit board is electrically connected to the LCD screen 33, which can perform data processing and back-end control on the image information on the LCD screen 33 to ensure the image quality of the LCD screen 33.

[0045] In some embodiments, the housing 31 is provided with heat dissipation holes 311, and the number of heat dissipation holes 311 is multiple and discretely arranged.

[0046] Specifically, both the outer shell 31 and the frame 310 are provided with heat dissipation holes 311 groups. There are multiple heat dissipation holes 311 groups on the outer shell 31, which are arranged at intervals along the edge contour direction of the outer shell 31. Each heat dissipation hole 311 group includes several of the above-mentioned heat dissipation holes 311, and the heat dissipation holes 311 are strip-shaped.

[0047] Therefore, the discretely arranged heat dissipation holes 311 can dissipate heat for the display module 30, preventing the display module 30 from overheating and affecting the operation of the internal electronic equipment.

[0048] In some embodiments, the frame 10 is an aluminum alloy frame 10.

[0049] The aluminum alloy frame 10 has good thermal conductivity and heat dissipation performance, which can quickly conduct heat from the display module 30 during use and dissipate it into the air, achieving the effect of cooling the display module 30. In addition, the aluminum alloy frame 10 has strong fatigue resistance and can be used for a long time.

[0050] In some embodiments, the glass cover 20 includes a touchscreen 200.

[0051] Therefore, image information can be converted through touch control, demonstrating the function of human-computer interaction.

[0052] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
