[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Example:

[0029] like Figures 1-8 As shown, this utility model provides a front frame structure for a frameless liquid crystal display module, including an upper front frame 1 and a lower front frame 2. The upper front frame 1 has a U-shaped structure and is fitted onto the display module 3. The bottom of the upper front frame 1 is snapped into the lower front frame 2.

[0030] Furthermore, a slot 4 is provided inside the upper front frame 1, which engages with the edge of the display module 3. The U-shaped upper front frame 1 does not require screws for fixing, greatly enhancing the aesthetics of the product.

[0031] Furthermore, the bottom of the upper front frame 1 is bent inward to form a bent portion 5. The length of the bent portion 5 is very short, only needing to accommodate the insertion hole 7, without affecting the normal installation of the upper front frame 1. The bent portion 5 has an L-shaped structure, and a retaining plate 6 is fixedly installed on the upper part of the bent portion 5. The retaining plate 6 is installed within the L-shaped space of the bent portion 5, and an insertion hole 7 is provided on the retaining plate 6. The insertion hole 7 is rectangular, and insertion blocks 8 are fixedly installed at both ends of the lower front frame 2. The insertion blocks 8 are adapted to and inserted into the insertion hole 7.

[0032] Furthermore, an installation space is reserved between the bottom of the card plate 6 and the bottom of the bending part 5, that is, the height of the bottom of the card plate 6 is higher than the height of the bottom of the bending part 5, and the installation space is used for the fitting and snapping of the lower front frame 2.

[0033] Furthermore, the lower front frame 2 includes a first fixing plate 21 and a second fixing plate 22, which are vertically fixedly connected. The first fixing plate 21 is disposed on the front side of the display module 3, and the width of the first fixing plate 21 is the same as the width of the front side of the upper front frame 1. The second fixing plate 22 is attached to the bottom of the display module 3, and the insert 8 is fixedly installed on the second fixing plate 22. The second fixing plate 22 is fixedly installed on the display module 3 using screws. Since the screws are installed at the bottom of the display module 3, they will not affect the aesthetics of the front frame of the display module 3.

[0034] The front width of the fixing plate 21 is the same as that of the upper front frame 1, so that the front frame of the display module 3 has a consistent width, making the edge of the front frame of the display module 3 neater and smoother, without abrupt transitions or gaps, increasing the overall aesthetics of the product, while also providing better protection and support.

[0035] Furthermore, extension plates 9 are fixedly installed at both ends of the fixing plate 22, and a groove 10 is provided at the front end of the extension plate 9. The insertion block 8 is vertically fixedly installed at the bottom of the groove 10.

[0036] Furthermore, the thickness and width of the extension plate 9 are adapted to the installation space.

[0037] The extension plate 9 of the lower front frame 2 is installed in the mounting space at the bottom of the upper front frame 1 to prevent the two ends of the lower front frame 2 from protruding outward or downward, which would make the outer edge of the entire front frame uneven and affect its aesthetics.

[0038] Furthermore, the upper front frame 1 and the lower front frame 2 are made of sheet metal, plastic, or aluminum profiles.

[0039] The front frame can be achieved through basic processes such as sheet metal bending and welding, or it can be replaced with plastic or aluminum profiles without changing the structural state.

[0040] Furthermore, such as Figure 8 As shown, multiple silicone pads 12 are attached to the periphery of the back plate 11 of the display module 3, namely the left, right and top sides near the upper front frame 1, and the silicone pads 12 are in contact with the inner side of the card slot 4.

[0041] The silicone pad 12 provides good support and limit, ensuring that after the lower front frame 2 and the upper front frame 1 are engaged, the four sides of the front frame structure are equal, meeting the requirements of the front shape of a conventional commercial display.

[0042] The working principle is as follows:

[0043] The U-shaped upper front frame 1 is slid into the display module 3 in a top-down sleeving manner, so that the clamping groove 4 of the upper front frame 1 is clamped on three edges of the display module 3; after the upper front frame 1 is installed, the plug blocks 8 at two ends of the lower front frame 2 are inserted into the plug holes 7 of the upper front frame 1 and are locked and fixed, so that four edges of the display module 3 are all provided with the front frame, the demand of the business display front appearance is met, meanwhile, the structure is simple in appearance, small in installation difficulty, low in cost and high in efficiency, meanwhile, the problem that the OC of the frameless product is not firmly bonded with the back plate and is fallen off can be avoided.

[0044] In the description of the utility model, it is understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "intermediate" indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, and not indicating or implying that the indicated device or element must have a specific orientation, structure and operation, therefore, it cannot be understood as a limitation of the utility model.

[0045] The above-mentioned is only a specific embodiment of the utility model, and cannot limit the scope of the utility model, so the replacement of equivalent components or equivalent changes and modifications made according to the utility model patent protection range should still belong to the scope covered by the utility model claim.
