Description

Technical Field

[0001] This utility model relates to the technical field of liquid crystal display modules, and specifically to a liquid crystal display module that is assembled together. Background Technology

[0002] The liquid crystal display module is the main component of a liquid crystal display device. The existing liquid crystal display module structure includes structural components such as front frame, liquid crystal display panel, middle frame, optical film, light guide plate, lamp bar and back cover. The frame plays the role of fixing the light guide plate and supporting the liquid crystal display panel. The frame structure is similar in different models. The front frame presses the liquid crystal display panel on the middle frame to fix the liquid crystal display panel.

[0003] Although snap-on LCD display modules have a simple structure and low cost, the snap-on clips are usually made of plastic. Long-term exposure to vibration (such as in vehicles or industrial equipment) or temperature changes can cause material creep, weakening the elasticity of the clips and eventually causing them to loosen or even break. Tiny gaps can easily form at the splicing points of the clips, allowing dust and liquids to seep in, requiring additional sealing with glue and increasing the complexity of the process. Summary of the Invention

[0004] The purpose of this invention is to provide a combined and installed liquid crystal display module to solve the above-mentioned defects caused by the prior art.

[0005] A combined liquid crystal display module includes a supporting housing, a front frame, a liquid crystal module, and a dustproof mesh. The supporting housing has an internal cavity, inside which the liquid crystal module is housed. The front frame is located on one side of the supporting housing, and a positioning mechanism is located on the outer side of the front frame. The outer side of the front frame is slightly larger than the surface of the supporting housing. The front frame engages with the outer side of the supporting housing for positioning. A double-layer isolation structure between the front frame and the supporting housing protects the outer side of the liquid crystal module. A dustproof mesh extends through the outer side of the supporting housing. A plate-type fan is bolted to the internal cavity. A locking mechanism is located on the outer side of the front frame, which locks the supporting housing and the front frame in place after engagement, preventing loosening of the engaged portion.

[0006] Preferably, the positioning mechanism includes a front frame, a first slot, a second slot, a horizontal locking strip, and a vertical locking strip. Horizontal locking strips are symmetrically arranged on both sides of the front frame, and vertical locking strips are symmetrically arranged on the other two sides of the front frame. The outer side of the horizontal locking strip is connected to the second slot, and the outer side of the vertical locking strip is connected to the second slot. The second slot is symmetrically arranged on the outer side of the supporting shell, and the other two sides of the outer side of the supporting shell are provided with the first slot.

[0007] Preferably, the supporting outer shell is connected to the transverse retaining strip through symmetrically opened slots, and the supporting outer shell is connected to the screw through a through-hole.

[0008] Preferably, the locking mechanism includes a polyurethane elastomer, positioning holes, a rubber sleeve, a nut, and a screw. The polyurethane elastomer is disposed on the outer side of the front frame. Positioning holes are rectangularly distributed on the outer side of the bearing housing. A nut is disposed on one side of the positioning hole. A rubber sleeve is glued to the tail end of the nut. The tail end of the nut is connected to the tail end of the screw. The top end of the screw is connected to one side of the front frame.

[0009] Preferably, the front frame is locked to the nut provided on one side of the bearing housing by rectangularly distributed screws.

[0010] Preferably, the front frame is bonded to the outer side of the load-bearing shell through a rectangular distribution of polyurethane elastomers on the outer side, and all four outer sides of the front frame adopt a chamfered structure.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. By setting up a rectangular distribution of screws, nuts, and positioning holes to form a rigid connection, combined with the auxiliary positioning of horizontal and vertical locking strips, the stability of the module under vibration or impact environment is greatly improved, avoiding the risk of loosening caused by plastic fatigue in snap-fit ​​type. On the one hand, polyurethane elastomer is used as a buffer material to absorb vibration energy and protect the LCD module from mechanical stress damage. On the other hand, polyurethane material can compensate for component size errors, avoiding assembly difficulties caused by tolerance in snap-fit ​​type.

[0013] 2. The plate fan and the "convex" structure of the inner cavity form a directional air duct. Together with the dustproof net, it blocks foreign objects, which facilitates the cooling of the back of multiple spliced ​​LCD display modules. This avoids the LCD display modules from getting too hot during long-term operation, which will affect the actual lifespan of the display modules. It is more efficient than the snap-on type that relies on natural heat dissipation and is suitable for high power consumption displays. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, a combined liquid crystal display module includes a supporting housing 1, a front frame 2, a liquid crystal module 3, and a dustproof mesh 13. The supporting housing 1 has an inner cavity 10, inside which the liquid crystal module 3 is housed. The front frame 2 is located on one side of the supporting housing 1, and a positioning mechanism 6 is located on the outer side of the front frame 2. The outer surface of the front frame 2 is slightly larger than the surface of the supporting housing 1. The front frame 2 engages with the outer surface of the supporting housing 1 for positioning. A double-layer isolation structure between the front frame 2 and the supporting housing 1 protects the outer surface of the liquid crystal module 3. The dustproof mesh 13 extends through the outer surface of the supporting housing 1. A plate fan 12 is bolted to the inside of the inner cavity 10. A locking mechanism 17 is located on the outer side of the front frame 2, which locks the supporting housing 1 and the front frame 2 after engagement, preventing the engaged parts from loosening.

[0023] In this embodiment, the positioning mechanism 6 includes a front frame 2, a first slot 7, a second slot 8, a horizontal locking strip 14, and a vertical locking strip 15. Horizontal locking strips 14 are symmetrically arranged on both sides of the front frame 2, and vertical locking strips 15 are symmetrically arranged on the other two sides of the front frame 2. The outer side of the horizontal locking strip 14 is connected to the second slot 8, and the outer side of the vertical locking strip 15 is connected to the second slot 8. The second slot 8 is symmetrically arranged on the outer side of the supporting shell 1. The other two sides of the outer side of the supporting shell 1 have the first slot 7. By setting the first slot 7 and the second slot 8 of different lengths, the front frame 2 is positioned, thereby facilitating the temporary locking and positioning of the front frame 2.

[0024] In this embodiment, the supporting shell 1 is connected to the transverse retaining strip 14 through symmetrically opened slots 8, and the supporting shell 1 is connected to the screw 16 through a through-hole 11. The screw 16 is positioned through the locating hole 11, which improves the convenience of positioning the supporting shell 1.

[0025] In this embodiment, the locking mechanism 17 includes a polyurethane elastomer 9, a positioning hole 11, a rubber sleeve 4, a nut 5, and a screw 16. The polyurethane elastomer 9 is disposed on the outer side of the front frame 2. The outer side of the bearing housing 1 has rectangularly distributed positioning holes 11. A nut 5 is disposed on one side of the positioning hole 11. The tail end of the nut 5 is glued to the rubber sleeve 4. The inner end of the nut 5 is connected to the tail end of the screw 16. The top end of the screw 16 is connected to one side of the front frame 2. The rubber sleeve 4 flexibly wraps the back of the nut 5, increasing the friction of the nut 5 and preventing the nut 5 from falling off during installation.

[0026] In this embodiment, the front frame 2 is locked to the nut 5 on one side of the supporting shell 1 by rectangularly distributed screws 16. The screws 16 are used to position one side of the front frame 2, which facilitates the assembly and positioning of the supporting shell 1 and the front frame 2.

[0027] In this embodiment, the front frame 2 is bonded to the outer side of the supporting shell 1 through polyurethane elastomers 9 distributed in a rectangular shape on the outer side. All four sides of the outer side of the front frame 2 adopt a chamfered structure. The gap between the front frame 2 and the supporting shell 1 is sealed by the polyurethane elastomers 9, thereby reducing the generation of gaps.

[0028] In practical applications, this type of combined LCD display module includes the following tasks:

[0029] Step 1: The operator first embeds the polyurethane elastomer 9 into the pre-set groove on the inner wall of the carrier housing 1 to ensure a complete fit without any warping, which serves as a buffer and seal. The liquid crystal driver board is then installed on the inner wall of the carrier housing 1 and connected to the liquid crystal module 3. Subsequently, the inner cavity 10 opened on the outer side of the carrier housing 1 is fitted to the back of the liquid crystal module 3. Since the side profile of the inner cavity 10 is a "convex" shaped structure, the "convex" shaped structure fits with the upper and lower sides of the liquid crystal module 3, so that the liquid crystal module 3 is parallel to one side of the plate fan 12. This allows the plate fan 12 to draw in outside air and circulate it to cool the back of the liquid crystal module 3.

[0030] Step 2: Then, align the symmetrically opened slots 7 and 8 on the outer side of the housing 1 with the horizontal and vertical strips 14 and 15 on the outer side of the front frame 2. Then, insert the horizontal and vertical strips 14 and 15 into the slots 7 and 8 to fit the housing 1 and the front frame 2 together. Use the front frame 2 to fit one side of the LCD module 3. At the same time, align the screw 16 on one side of the front frame 2 with the positioning hole 11 and insert the screw 16 through the positioning hole 11.

[0031] Step 3: At the same time, the polyurethane elastomer 9 on the outer side of the bearing shell 1 is bonded to the inner end of the front frame 2, so that the polyurethane elastomer 9 fills the gap at the connection between the bearing shell 1 and the front frame 2. The deformation of the polyurethane elastomer 9 is used to self-adapt and fix it, avoiding hard contact. The bearing shell 1 is wrapped by the outer side of the front frame 2, which is the only bearing shell 1, to improve the impact resistance of the bearing shell 1.

[0032] Step 4: Then, by holding the rubber sleeve 4 on the back of the nut 5, the nut 5 is threaded to the outside of the screw 16. The nut 5 is pre-tightened on the back of the bearing housing 1, but not completely locked, leaving room for adjustment, so that the bearing housing 1 and the front frame 2 are tightly fixed in place. The internal liquid crystal module 3 is filtered by the dustproof net 13 on the back of the bearing housing 1. The plate fan 12 rotates continuously to circulate and inject air. The "convex" inner cavity (10) forms a directional air duct, which is directly injected into the interior of the bearing housing 1 and the front frame 2 to form an installation space, thereby cooling the liquid crystal module 3 and the liquid crystal driver board.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
