Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal modules, and particularly relates to a liquid crystal module with a snap-on back shell. Background Art

[0002] For all display products such as monitors and TVs, while pursuing display effects and performance, the pursuit of product styling is also continuously improved. Exquisite appearance, low cost, and convenient maintenance have become one of the topics that are constantly explored and studied. Currently, all existing backlight modules use a set of backplates (back shells) as the main structure. The backlight materials can only be stacked and assembled from the inside of the machine, and the overall strength is relatively soft. If a front iron plate is used as the backplate, its weight is large and it is difficult to handle. In addition, the current backplate structure of the whole iron plate is fixed at both ends, making disassembly and assembly inconvenient. Content of the Utility Model

[0003] The utility model aims to overcome at least one defect of the above-mentioned prior art, and provides a liquid crystal module with a snap-on back shell to achieve the purpose of convenient disassembly and assembly and simple structure.

[0004] The utility model provides a liquid crystal module with a snap-on back shell, which includes a top side end and a bottom side end. From the front to the back, there are successively arranged a liquid crystal panel, a film sheet, a glass light guide plate, a reflective paper, an iron backplate radiator, and a back shell; a lamp bar is also arranged at the bottom side end of the glass light guide plate; the iron backplate radiator forms a semi-enclosed space at the bottom side end for the heat dissipation of the lamp bar; the other end of the iron backplate radiator is provided with a plurality of bridge bayonets; the back shell is correspondingly provided with a plurality of bridge card strips inserted into the bridge bayonets.

[0005] Different from the whole iron backplate in the prior art as the backplate, multiple screws are required to fasten the subsequent back shell, and the fastening effect is not good. Since the lamp bar in the liquid crystal module is the main heat-generating component, the whole iron backplate appears heavy and difficult to transport. Therefore, the utility model adopts the structure of a partial iron backplate radiator. After the assembly of other components is completed, the overall rapid installation is realized by using the bridge structure to snap-fit with the back shell, reducing the installation cost, and multiple bridge bayonets also play a positioning role at the same time, improving the installation efficiency.

[0006] Further, the bridge bayonets are on the same horizontal line, and the number of the bridge bayonets is 7 - 10. In order to ensure stability in the horizontal direction, 7 - 10 bridge bayonets are preferably designed and distributed in a horizontal straight line to ensure the tight fit between the back shell and the upper side of the iron backplate radiator.

[0007] More preferably, the number of the bridge bayonets is 8; and the distance between the midpoints of the two bridge bayonets at both ends is 500 - 520 mm. More preferably, the distance between each two bridge bayonets is 60 - 100 mm.

[0008] Furthermore, positioning bayonets are provided at the midpoints of the two bridging bayonets at both ends, and the rear case is provided with locking blocks that cooperate with the positioning bayonets. To facilitate the positioning of the bridging bayonets, the present utility model preferably designs positioning bayonets, which are designed at the midpoint of the straight line where the bridging bayonets are located, improving the latching efficiency.

[0009] Furthermore, first threaded holes and second threaded holes are respectively provided at both ends of the ground side of the iron backplane radiator. The liquid crystal module further includes a first screw and a second screw, and the rear case is fixed to the first threaded holes and the second threaded holes through the first screw and the second screw.

[0010] Preferably, a third threaded hole is further provided at the midpoint between the first threaded hole and the second threaded hole. The liquid crystal module further includes a third screw, and the rear case is fixed to the third threaded hole through the third screw.

[0011] In the present utility model, the ground side of the iron backplane radiator is a flanging structure, which is flanged from the back to the whole surface, and the tail end is embedded between the liquid crystal panel and the glass light guide plate, and is attached to the glass light guide plate, being in the same plane as the diaphragm. Moreover, the positions of the ground side of the iron backplane radiator near the light bar protrude towards both sides, forming a heat dissipation space to facilitate the heat dissipation of the light bar.

[0012] More preferably, the distance between the first threaded hole and the second threaded hole is 500 - 530 mm; the distance between the straight line where the bridging bayonet is located and the straight line where the first threaded hole and the second threaded hole are located is 90 - 110 mm.

[0013] Furthermore, an F-shaped frame is provided at the sky side. The liquid crystal module further includes a decorative film, and the decorative film is attached to the back of the reflective paper. The F-shaped frame includes an integrally formed support part, a first fixing part, and a second fixing part; the first fixing part is provided at the top of the support part, and the included angle with the support part is less than 90 degrees; the second fixing part is perpendicular to the support part, the support part is attached to the sky side of the liquid crystal module, the first fixing part internally buckles and fixes the decorative film; the second fixing part is embedded between the liquid crystal panel and the diaphragm.

[0014] Furthermore, the rear case extends from the back to the front and is provided with a notch. The liquid crystal module further includes a patch front frame, one end of the patch front frame is embedded in the notch, and the other end is attached to the liquid crystal panel; a first double-sided foam adhesive is provided between the second fixing part and the liquid crystal panel; second foam adhesives are respectively provided between the decorative film and the reflective paper; a edge wrapping adhesive is further provided at the sky side of the liquid crystal module, one end of the edge wrapping adhesive is embedded between the decorative film and the second foam adhesive, and the other end is embedded between the second fixing part and the diaphragm.

[0015] Using a glass light guide plate and a liquid crystal panel, an iron radiator as the main structure, and a plastic rear shell as the appearance structure. The rear shell does not need to cover the entire back of the liquid crystal module, only partial coverage is required. Use an F card slot to snap together the iron backplane radiator, the glass light guide plate, and the film, and then attach the liquid crystal panel to the F card slot. Change the existing backlight method, and then use screw and buckle designs, which not only save materials and processes but also achieve a product form where the backlight source can be universal, and can be applied to the display product design of all side-light backlight modules.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] The present utility model uses an iron backplane radiator to snap together the liquid crystal module of the rear shell as the backlight source of a TV or a monitor, which is convenient for disassembly and installation, and has high stability. At the same time, a whole iron backplane is not required, reducing the overall weight and making the installation more convenient. Use glass material as the main structure of the light guide plate, and at the same time wrap the iron backplane radiator and the film, and then snap them into the F frame card slot. Finally, use the bridge structure on the iron backplane radiator to snap together the rear shell, and at the same time, the flanging tapping holes on the iron radiator fix the lower side of the rear shell. Finally, attach the patch front frame. The comprehensive cost of the product is low, the production efficiency is high, the appearance is exquisite, and the thickness is ultra-thin; the modularization and standardization of the backlight module can be used to reduce the development and manufacturing costs.
