[0033] Reference Figures 1-6 , this embodiment provides a structure for quick disassembly of a built-in buckle, which is designed specifically for electronic plastic parts to achieve quick and non-destructive disassembly. The structure includes the main body 1 and the rear shell 2 of the electronic plastic part, and the two are connected through a hidden buckle structure, so that the buckle structure is built-in between the main body 1 and the rear shell 2 after connection, keeping the appearance neat.

[0034] The design of the buckle structure is that the buckle structure consists of a buckle part 3 and a buckle groove 4, and the buckle part 3 is elastically designed for easy quick disassembly.

[0035] The design of the thimble group is that the thimble group consists of a thimble 6 and a thimble seat 7. By inserting the thimble 6 into the buckle groove 4 and pressing the thimble seat 7, the ejection of the buckle part 3 is realized. The cooperation of the thimble group and the main body 1 is that there is a jack 5 on one side of the bottom of the main body 1 close to the rear shell 2 for the thimble group to insert.

[0036] The setting of the buckle structure for the cooperation of the thimble group is that a bevel 31 is designed on the insertion side of the buckle part 3 to facilitate the insertion and ejection disassembly operation of the thimble 6; one side of the buckle part 3 opposite to the insertion side is set as a table surface 32, which forms a firm buckle connection with the edge of the buckle groove 4.

[0037] In order to facilitate the insertion of the thimble 6 and its cooperation with the bevel 31, the jack 5 is arranged opposite to the insertion side of the buckle part 3. And a thimble groove 8 is arranged inside the main body 1, which is communicated with the jack 5 to provide stable guidance and support for the thimble 6.

[0038] In order to facilitate the ejection of the thimble 6 and avoid damage to parts, the thimble 6 is also provided with a first insertion end 61 and a second insertion end 62. The cross-sectional width of the first insertion end 61 is adapted to the jack 5, and the cross-sectional width of the second insertion end 62 is smaller, which is convenient for passing through the connection area between the rear shell 2 and the main body 1 and inserting into the buckle groove 4. The connection area between the rear shell 2 and the main body 1 is the area where the bottom of the rear shell 2 to the buckle part 3 fits on the inner side wall of the main body 1 after the buckle structure is connected.

[0039] The size of the ejector pin 6 is set, and the second insertion end 62 is a small end, which is used to insert and pass through the connection area between the rear shell 2 and the main body 1 to realize the ejection of the snap member 3 from the snap slot 4. The thickness setting of the second insertion end 62 can ensure that a small gap can be created between the rear shell 2 and the main body 1 to form a good gap so that the second insertion end 62 can be inserted into the snap slot 4 for operation, and can also ensure that the ejection gap is small enough to avoid the risk of excessive bending of the rear shell 2 causing cracks or direct breakage of the rear shell 2.

[0040] The first insertion end 61 is a large section, which is used to be inserted into the socket 5 and cooperate with the ejector groove 8. The first insertion end 61 is assembled with the ejector seat 7, and is used to apply external force to facilitate the ejector 6 to eject the fastener 3. Therefore, the thickness of the first insertion end 61 is set to meet the strength requirements, avoid stress concentration at the first insertion end 61 when external force is applied, avoid the risk of fatigue or breakage of the first insertion end 61 under long-term load, and ensure that the ejector 6 can be reused.

[0041] In this embodiment, in order to better realize the assembly of the body 1 and the rear shell 2, a double buckle structure is provided to form a connection. Specifically, two buckles 3 are provided on the rear shell 2, and the buckles 3 are elastic buckles 3, and two buckle grooves 4 are provided on the body 1 at positions corresponding to the two buckles 3. Two insertion holes 5 are provided at the bottom of the body 1 corresponding to the insertion side of each buckle 3 to adapt to the design of the double buckles 3.

[0042] At the same time, two ejector pins 6 are mounted on the ejector pin seat 7, which are arranged at intervals and correspond to the positions of the two fasteners 3, respectively, so as to realize precise ejection and simultaneous ejection. Two holes are arranged on the ejector pin seat 7 for fixing the ejector pins 6, and the spacing, length, thickness, etc. of the two ejector pins 6 can be determined by the product.

[0043] In this embodiment, the rear shell 2 is built into the body 1, and a snap member 3 is provided on the rear side of the rear shell 2, and the snap member 3 protrudes from the rear shell 2. A snap groove 4 is provided on the rear side of the body 1, and the snap groove 4 is concavely provided on the inner side of the body 1. In order to facilitate the insertion of the ejector pin 6 and form an extrusion and give way, a slope 21 is designed at the bottom of the rear shell 2, and the slope 21 is provided on the same side as the snap member 3. The slope 21 can be formed by chamfering a corner of the bottom of the rear shell 2. The setting of the slope 21 cooperates with the setting of the inclined surface 31 of the snap member 3, which can reduce the loss of parts during disassembly, is less destructive to the product, and makes the product reusable. At the same time, the rework efficiency can also be improved. Rework is inevitable during production, and this structural design improves the disassembly efficiency during rework.

[0044] The design of the buckle structure and the ejector pin group in this embodiment can achieve the rapid detachment of the buckle part 3 and the damage-free disassembly of the outer shell and the body 1 on the premise of ensuring the minimum deformation of the buckle part 3, ensuring the integrity and reusability of the plastic parts. It not only improves the assembly and disassembly efficiency of electronic plastic parts, but also ensures the aesthetics and durability of the product, meeting the requirements of modern electronic devices for rapid assembly and maintenance. The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive modifications to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
