The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Example 1

[0033] Combination Figures 1 to 7 As shown, the display module 100 of this utility model is schematically displayed, including a first mounting part 10, a second mounting part 20, and a circuit board 30.

[0034] like Figure 1 The first mounting part 10 is provided with a connecting post 11. The connecting post 11 is preferably set perpendicular to the first mounting part 10. The connecting post 11 has a snap-fit ​​arm 111. The snap-fit ​​arm 111 itself has a certain elasticity, and one end of it is connected to the connecting post 11, while the other end is set away from the connecting post 11.

[0035] like Figure 2 and Figure 5 The second mounting part 20 is provided with a first mounting post 21. The first mounting post 21 is preferably set perpendicular to the second mounting part 20. The first mounting post 21 is provided with a connecting hole 211, which is coaxial with the first mounting post 21.

[0036] The circuit board 30 has a mounting hole 31 and is located between the first mounting part 10 and the second mounting part 20. A first mounting post 21 passes through the mounting hole 31. The first mounting post 21 and the mounting hole 31 can limit the circuit board 30 and prevent the circuit board 30 from sliding relative to the second mounting part 20. A connecting post 11 passes through the connecting hole 211, and a snap-fit ​​arm 111 snaps into the connecting hole 211. By pulling the first mounting part 10 and the second mounting part 20, or by inserting a tool into the connecting hole 211 to disengage the snap-fit ​​arm 111, the first mounting part 10 and the second mounting part 20 can be disassembled without turning screws, simplifying the disassembly and assembly steps.

[0037] The arrangement of the first mounting post 21 and the mounting hole 31 also prevents the connecting post 11 and / or the snap-fit ​​arm 111 from directly contacting the circuit board 30. This prevents the impact force from being transmitted to the circuit board 30 through the connecting post 11 or the snap-fit ​​arm 111 when the first mounting part 10 and / or the second mounting part 20 are subjected to impact.

[0038] Specifically, the connecting post 11 has a head end 11a and a tail end 11b, which are combined with Figure 4As shown, the first end 11a of the connecting post 11 is connected to the first mounting part 10, and the tail end 11b of the connecting post 11 is provided with a separation groove 112 so that the tail end 11b of the connecting post 11 forms two oppositely arranged snap-fit ​​arms 111. This makes the cross-section of the connecting post 11 Y-shaped. This structure not only enables the snap-fit ​​arms 111 to be mutually snapped with the connecting hole 211, but also simplifies the processing technology of the connecting post 11, enabling the connecting post 11 to be processed at low cost. The connecting post 11 is provided with a thinning hole 113 arranged coaxially with it. The setting of the thinning hole 113 makes the thickness of the snap-fit ​​arms 111 thinner and more flexible. The locking arm 111 is provided with a limiting block 111a, which is arranged radially outward towards the connecting post 11. The limiting blocks 111a on the two locking arms 111 of the connecting post 11 are arranged opposite to each other. The limiting blocks 111a can be locked at the step of the connecting hole 211. Of course, in order to allow the locking arm 111 to smoothly pass into the connecting hole 211 during the assembly of the first mounting part 10 and the second mounting part 20, the limiting block 111a is provided with a guide cone surface. The generatrix of the guide cone surface is inclined to the axis of the connecting post 11. During the assembly of the first mounting part 10 and the second mounting part 20, the guide cone surface first abuts against the connecting hole 211. The connecting hole 211 slides relative to the guide cone surface and forces the locking arm 111 to undergo elastic deformation, so that the two locking arms 111 move closer to each other and extend into the connecting hole 211, and finally lock into the step inside the connecting hole 211. When disassembling the first mounting part 10 and the second mounting part 20, a tool is inserted into the connecting hole 211 to force the two locking arms 111 to move closer to each other, so that the locking arms 111 can be disengaged from the connecting hole 211.

[0039] Furthermore, the connecting hole 211 has a first hole section 211a and a second hole section 211b, which are combined with Figure 5 As shown, the second hole segment 211b is closer to the second mounting part 20 than the first hole segment 211a. The inner diameter of the first hole segment 211a is smaller than the inner diameter of the second hole segment 211b. A first step 211c is formed between the first hole segment 211a and the second hole segment 211b. The limiting block 111a on the locking arm 111 is engaged with the first step 211c to prevent the first mounting part 10 and the second mounting part 20 from disengaging.

[0040] Combination Figure 5 and Figure 6As shown, to stably support the circuit board 30, the second mounting portion 20 is provided with a second mounting post 22, and a first mounting post 21 is provided at one end of the second mounting post 22. The first mounting post 21 and the second mounting post 22 are coaxially arranged, wherein a first hole segment 211a is located inside the first mounting post 21, and a second hole segment 211b is located inside the second mounting post 22. The outer diameter of the second mounting post 22 is larger than the outer diameter of the first mounting post 21, and a second step 221 is formed between the first mounting post 21 and the second mounting post 22. The circuit board 30 abuts against the second step 221. In this embodiment, the number of first mounting posts 21 and the number of second mounting posts 22 are the same and there are multiple of each. Correspondingly, the circuit board 30 is provided with multiple mounting holes 31, and the number of mounting holes 31 is the same as the number of first mounting posts 21. When the second mounting part 20 is uneven on one side where the circuit board 30 is mounted due to factors such as molding process, functional area layout, and structural verification, the second steps 221 protruding from the multiple second mounting posts 22 of the second mounting part 20 can all be on the same plane to support the circuit board 30.

[0041] To prevent the adhesive applied to the circuit board 30 from entering the connection hole 211, the length of the first mounting post 21 is greater than the thickness of the circuit board 30. This allows one end of the first mounting post 21 to protrude through the mounting hole 31 on the circuit board 30. Therefore, the opening of the connection hole 211 is higher than the surface of the circuit board 30, preventing adhesive intrusion. A gap 40 is provided between the first mounting part 10 and the circuit board 30, and the gap 40 is filled with adhesive. After the adhesive solidifies, it can improve the waterproof and dustproof performance of the circuit board 30.

[0042] In this embodiment, there are multiple and the same number of connecting posts 11 and connecting holes 211. Each connecting post 11 corresponds to one connecting hole 211. The multiple connecting posts 11 are arranged in a matrix. The arrangement of multiple connecting posts 11 and multiple connecting holes 211 can significantly improve the connection stability between the first mounting part 10 and the second mounting part 20.

[0043] Example 2

[0044] Combination Figure 8 As shown, this embodiment discloses a display device 1, including the display module 100 as described above. The first mounting part 10 can be a mask, the second mounting part 20 can be a bottom shell, and a plurality of LED beads are disposed on the circuit board 30. When the number of LED beads is set to multiple, different combinations of LED bead colors and brightness can form a display screen. The LED beads are arranged facing the first mounting part 10.

[0045] In summary, the circuit board 30 is disposed between the first mounting part 10 and the second mounting part 20. The connecting post 11 on the first mounting part 10 has a snap-fit ​​arm 111, and the mounting post of the second mounting part 20 has a connecting hole 211. The mounting post passes through the mounting hole 31 on the circuit board 30 to limit the positioning of the circuit board 30. The connecting post 11 passes through the connecting hole 211, and the snap-fit ​​arm 111 snaps into the connecting hole 211, thereby achieving the snap-fit ​​between the first mounting part 10 and the second mounting part 20, eliminating the need for the existing screw avoidance structure. The arrangement of the mounting post and the mounting hole 31 can prevent the connecting post 11 and the snap-fit ​​arm 111 from directly contacting the circuit board 30, so as to prevent the impact force from being transmitted to the circuit board 30 when the first mounting part 10 and / or the second mounting part 20 are impacted.
