DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the application.

[0035] As Figures 1 to 12As shown, the circuit board quick disassembly module of the present application is provided with a circuit board 1 and a positioning assembly 2 arranged at the four corners of the circuit board 1, and the actual number of the positioning assembly 2 can be arranged according to the structure of the actual circuit board 1. Some circuit boards 1 have special-shaped structures or strip-shaped structures, and mounting holes 3 matched with the positioning assembly 2 can be formed on the circuit board 1 according to the actual situation, so as to facilitate the positioning of the circuit board 1 by the positioning assembly 2.

[0036] The positioning assembly 2 comprises a positioning seat 4, a positioning piece 5, a pressing piece 6 and a limiting piece 7. The positioning seat 4 is fixed on the frame or body of the electronic product, so that it can be kept stationary. The fixing mode of the positioning seat 4 can be an integral structure with the frame or body of the electronic product, or a later fixed structure, such as a bolt or screw fixing mode, or other structure fixing mode. The positioning piece 5 cooperates with the positioning seat 4 to limit the circuit board 1 to be positioned between the positioning seat 4 and the positioning piece 5, so as to keep the circuit board 1 stable. The pressing piece 6 is used to push and limit the position of the limiting piece 7, so that it can move in the middle of the positioning piece 5 and change the height to limit and accommodate the limiting body 8. The positioning piece 5 can keep the position of the circuit board 1 limited, and no other tools are needed during disassembly, and the operation is simple. The cooperation between the positioning piece 5 and the positioning seat 4 is stable, and the quick disassembly of the circuit board 1 can be realized, which is beneficial to improve the convenience and save time of the disassembly work of the circuit board 1, and avoid the damage of parts caused by frequent disassembly work.

[0037] A positioning hole 9 is formed in the middle of the positioning seat 4, an annular groove 10 is arranged in the positioning hole 9, and an inverted conical surface 11 is arranged at the opening of the positioning hole 9. The positioning hole 9 is used to accommodate a second positioning body 12, and the annular groove 10 is used to accommodate the limiting body 8. Since the annular groove 10 is arranged in a ring shape, the position of the limiting body 8 can be limited by the annular groove 10 when the positioning piece 5 rotates, so that the pressing piece 6 can be pressed towards the direction that the worker can see, which is convenient for the worker to disassemble.

[0038] The lower end of the positioning piece 5 is inserted into the positioning hole 9, the inside of the positioning piece 5 is provided with a horizontal hole 13 and a vertical hole 14, the horizontal hole 13 and the vertical hole 14 are arranged vertically and in communication, a through hole 15 is arranged at the vertical hole 14, and a limiting body 8 is arranged in the through hole 15.

[0039] The positioning member 5 is composed of a first positioning body 16 and a second positioning body 12, the diameter of the first positioning body 16 is larger than that of the second positioning body 12, and the diameter of the second positioning body 12 is matched with the inner diameter of the mounting hole 3 and the positioning hole 9. The transverse hole 13 is arranged in the middle of the first positioning body 16, and the vertical hole 14 is arranged in the middle of the first positioning body 16 and the second positioning body 12, and the upper end of the vertical hole 14 is kept open, while the transverse hole 13 is kept open at one end and closed at the other end, which facilitates limiting the position of the first spring 17 and the pressing member 6 through the transverse hole 13.

[0040] The through hole 15 is provided with a guide inclined surface 18, the diameter of one end of the through hole 15 close to the vertical hole 14 is H1, the diameter of the other end of the through hole 15 away from the vertical hole 14 is H2, and the diameter of the limiting body 8 is H3, H1>H3>H2. Since the diameter of one end of the through hole 15 is larger and the diameter of the other end is smaller, the limiting body 8 cannot fall out of the smaller end of the through hole 15, and the larger end is limited by the limiting member 7, and at the same time, the limiting member 7 can accommodate the limiting body 8 in the accommodating hole 19, so that the limiting body 8 enters the through hole 15 and the accommodating hole 19 from the annular groove 10 and the through hole 15. Since the limiting body 8 cannot fall out of the smaller end of the through hole 15, a part of the limiting body 8 will enter the annular groove 10, thereby cooperating with the limiting member 7 to resist the limiting body 8, so that the part of the limiting body 8 entering the annular groove 10 cannot be pushed, the position of the limiting body 8 is limited, the limiting relationship between the positioning member 5 and the positioning seat 4 is ensured, the positioning member 5 cannot be moved out without pressing the pressing member 6, the stability of the installation of the circuit board 1 is improved, and the convenience of the installation of the positioning assembly 2 is ensured.

[0041] The pressing member 6 is arranged in the transverse hole 13, the middle of the pressing member 6 is provided with a guide groove 20, the first spring 17 is arranged in the transverse hole 13, and one end of the first spring 17 is in contact with the pressing member 6.

When the third blocking plane 27 contacts the first blocking plane 23, the accommodating opening 19 is kept horizontal with the through hole 15, so that the limiting body 8 is kept in the through hole 15 and the accommodating opening 19. When the third blocking plane 27 contacts the second blocking plane 25, the accommodating opening 19 is kept lower than the through hole 15, so that the limiting body 8 contacts the inclined surface 28, and the limiting body 8 is kept in the through hole 15 and the annular groove 10, thereby limiting the position of the limiting body 8.

[0044] The limiting member 7 is arranged in the vertical hole 14, and the lower end of the limiting member 7 is provided with a second spring 29 arranged in the vertical hole 14. The elastic force of the first spring 17 is greater than that of the second spring 29, so that the second spring 29 only provides an elastic force for the limiting member 7, so that the guide end 30 can be kept in the guide groove 20, and the first spring 17 cannot push the pressing member 6 to keep the guide end 30 from entering the first guide slope 24 from the second guide slope 26.

[0045] The upper end of the limiting member 7 forms a guide end 30 matched with the guide groove 20, and the limiting member 7 is provided with an accommodating opening 19 for accommodating the limiting body 8. The accommodating opening 19 is provided with an arc surface 31 and an inclined surface 28, and the accommodating opening 19 is used for accommodating the limiting body 8 and limiting the position of the limiting body 8 through the inclined surface 28. The limiting body 8 is guided by the first guide slope 18 and rolls into the accommodating opening 19 under the action of gravity. When the limiting body 8 moves downward, the limiting body 8 is pushed into the through hole 15 through the inclined surface 28.

The upper end of the guide end 30 is provided with a third guide slope 33 matched with the first guide slope 24 and the second guide slope 26, and a third blocking plane 27 matched with the first blocking plane 23 and the second blocking plane 25.

[0047] The first spring 17 pushes the pressing member 6, keeps the pressing member 6 pushing the limiting member 7 to compress the second spring 29, and pushes the limiting body 8 in the accommodating opening 19 and the through hole 15 into the through hole 15 and the annular groove 10.

[0048] As Figure 12When the circuit board 1 needs to be positioned, the circuit board 1 can be placed on the positioning seat 4 first, the mounting hole 3 is kept corresponding to the positioning hole 9, then the pressing piece 6 is pressed, the first spring 17 is kept being pushed by the pressing piece 6, the first spring 17 is compressed, the limiting piece 7 is not pressed by the first spring 17 at this time, the pressing piece 6 moves to the direction of the first spring 17, the second spring 29 pushes the limiting piece 7 upwards under the elastic force of the second spring 29, the guide end 30 on the limiting piece 7 can reach the first guide inclined surface 24 from the second guide inclined surface 26, the third blocking plane 27 changes from being in contact with the second blocking plane 25 to being in contact with the first blocking plane 23, the accommodating opening 19 at the lower end of the through hole 15 reaches the height of the through hole 15, the limiting body 8 can enter the accommodating opening 19 under the guidance of the guide inclined surface 18, then the lower end of the positioning piece 5 can be inserted into the positioning hole 9 through the mounting hole 3, then the external force applied to the pressing piece 6 is cancelled, the pressing piece 6 is pushed back under the elastic force of the first spring 17, the pressing piece 6 keeps pushing the limiting piece 7, the limiting piece 7 compresses the second spring 29, the inclined surface 28 in the accommodating opening 19 pushes the limiting body 8 to the through hole 15 and the annular groove 10, the position between the positioning piece 5 and the positioning seat 4 is limited by the limiting body 8. When the circuit board 1 needs to be disassembled, the pressing piece 6 only needs to be pressed, then the positioning piece 5 is taken out, the pressing piece 6, the first spring 17, the second spring 29, the limiting piece 7 and the limiting body 8 in the positioning piece 5 are taken out.
