Description

Technical Field

[0001] This utility model relates to the field of LCD module technology, and more specifically to an LCD module with a snap-fit ​​mechanism. Background Technology

[0002] Conventional LCD modules require double-sided tape for fixing when assembled with the main unit. During assembly, they are often tilted or tilted to one side, resulting in the LCD module not being assembled properly or the window position being misaligned. This requires manual disassembly and reassembly, which wastes manpower and affects efficiency.

[0003] Therefore, based on the aforementioned shortcomings of existing LCD modules, improvements to existing LCD modules are necessary. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An LCD module with a snap-fit ​​mechanism includes a main body. The bottom surface of the main body is provided with a positioning structure for quick positioning and fixing with a motherboard. The positioning structure includes at least two positioning posts and at least one snap-fit. The positioning posts and the snap-fit ​​work together to achieve a mechanical connection between the LCD module and the motherboard by inserting them into corresponding positioning holes and slots on the motherboard.

[0007] In some embodiments, the positioning post includes a first positioning post and a second positioning post, and the latch includes a positioning latch; wherein:

[0008] The first positioning post is located near the top of the bottom surface of the main body and is used to cooperate with the positioning hole at the top of the main board.

[0009] The second positioning post is located near the bottom of the main body and is used to cooperate with the positioning hole at the bottom of the main body;

[0010] The positioning buckle is located near the top of the main body and is used to embed into the corresponding slot of the motherboard to form a fastening and fixing.

[0011] In some embodiments, the first positioning post is a cylindrical structure, vertically formed at the top edge of the bottom surface of the main body.

[0012] In some embodiments, the second positioning post is a rectangular boss structure that extends along the bottom edge of the main body.

[0013] In some embodiments, the positioning buckle is an elastic barb structure with an inclined guide surface at its end for guiding the buckle into the motherboard slot and locking it.

[0014] In some embodiments, the main body is a plastic frame structure, with an integrated FOG screen and a flexible circuit board on its front side, and the flexible circuit board is connected to the FOG screen.

[0015] In some embodiments, the first positioning post, the second positioning post, and the positioning buckle cooperate with the corresponding positioning holes and slots on the motherboard to form a three-point positioning structure, which restricts the displacement of the LCD module in the horizontal direction.

[0016] The advantages of this utility model compared with the prior art are:

[0017] Rapid positioning: Precise horizontal positioning is achieved by aligning the first and second positioning posts with the positioning holes on the motherboard;

[0018] Secure locking: The elastic barbed structure of the positioning buckle cooperates with the motherboard slot to form a vertical lock, preventing the module from coming out;

[0019] High-efficiency assembly: The three-point positioning structure (two pillars and one buckle) simplifies manual operation, adapts to automated production lines, and improves assembly efficiency. Attached Figure Description

[0030] Example 1:

[0031] This invention has a simple structure and low cost, and can be widely used in consumer electronics, industrial equipment, automotive displays and other fields, and is especially suitable for large-scale automated production scenarios.

[0032] See Figure 1-4 As shown, an LCD module with a snap-fit ​​mechanism includes a frame 2, a FOG screen 3, and a flexible circuit board 4. The bottom surface of the frame 2 is provided with a positioning structure, which includes:

[0033] First positioning post 6: cylindrical structure, vertically formed on the top edge of the bottom surface of the frame 2, used to insert into the positioning hole at the top of the main board;

[0034] Second positioning post 5: Rectangular boss structure, extending along the bottom edge of the bottom surface of the frame 2, used to insert into the positioning hole at the bottom of the motherboard;

[0035] Positioning buckle 1: elastic barb structure, set near the top of the rubber frame 2, with an inclined guide surface at its end for embedding into the motherboard slot and locking.

[0036] The frame 2 integrates the FOG screen 3 and the flexible circuit board 4 on its front.

[0037] During assembly:

[0038] Align the first positioning post 6 with the circular positioning hole at the top of the motherboard, and align the second positioning post 5 with the rectangular positioning hole at the bottom of the motherboard.

[0039] Apply light pressure to the module so that the inclined guide surface of the positioning buckle 1 contacts the edge of the motherboard slot and is elastically deformed before being embedded inside the slot.

[0040] Clip 1 resets and locks in place, while positioning pins 5 and 6 are fully inserted into the motherboard positioning holes, completing the mechanical fixation of the module to the motherboard.

[0041] In another embodiment, the second positioning post 5 can be replaced by a plurality of symmetrically distributed protrusions to further increase the horizontal limiting strength; the angle of the barb of the positioning buckle 1 can be adjusted according to the depth of the motherboard slot to adapt to the needs of different models.

[0042] When assembling the module into the whole machine, the positioning pins of the module are directly aligned with the positioning holes and buckle slots of the whole machine, and then the positioning pins of the motherboard are used to fasten it, achieving rapid positioning. The overall assembly process is simple and the assembly efficiency is high.

[0043] Tests have shown that the assembly time of LCD modules using this invention is reduced by 60% compared to traditional double-sided tape fixing, and the yield rate is increased to over 99.5%, effectively solving the problems of skewing and rework.
