Nowadays, the assembly of the upper and lower casings of the mainframe of the notebook computer generally depends on the fastening of the hooks and the slots, and the upper casing is locked to the lower casing by screws. However, if there is not enough space in the connection area of the upper and lower housings to design locking screws and screw sleeves that are screwed with the locking screws, the hooks and slots of the upper and lower housings will be damaged when the upper housing and the lower housing are assembled. shell plays a key role.

Please refer to Fig. 1A and Fig. 1B, in the prior art, a hook 11 is provided on the upper casing 1 of the notebook computer host, and a slot 21 corresponding to the hook 11 is provided on the lower casing 2, and the Both sides of the slot 21 are connected to the lower case 2 (please refer to the circled part 25 in FIG. 1B ). Elastic deformation will occur along the direction of force (as shown in direction a of Figure 1B), and since the card slot 21 is integrated with the lower case 2, the card slot 21 will follow the deformation of the lower case 2 to produce an offset , that is, the locking slot 21 will be displaced in the direction a.

Please refer to FIG. 1C again. FIG. 1C is an assembly diagram of the upper casing 1 and the lower casing 2 of the laptop mainframe being engaged with each other through the hook 11 and the slot 21 . In the above, when the pressure F is applied to the force-receiving part 23 of the lower case 2, the slot 21 will follow the deformation of the lower case 2 to displace, and the displacement direction is as shown in the direction a in the figure, and the hook 11 is provided on the upper case 1 and has nothing to do with the pressure F, that is, the hook 11 does not shift with the deformation of the lower case 2. The direction is deviated to cause the hook 11 to be decoupled from the slot 21 , thereby causing the upper and lower shells to fall off.

Therefore, how to design a buckle structure that can combine the upper shell and the lower shell and has the function of preventing decoupling is an urgent problem to be solved at present.

Please refer to FIG. 2A , FIG. 2B and FIG. 2C . FIG. 2A , FIG. 2B and FIG. 2C are schematic diagrams of the disassembly and assembly structure of the buckle structure with decoupling prevention function of the present invention. The buckle structure with anti-decoupling function of the present invention is used to combine the upper shell 3 and the lower shell 4 , and includes a buckle 31 , an engaging piece 41 , and a protrusion 45 . In this embodiment, the upper and lower casings can be, for example, the casing of a notebook computer, especially the upper and lower casings of the host computer of the notebook computer.

As shown in FIG. 2A , the buckle 31 is disposed inside the upper housing 3 , and the buckle 31 has a hook 311 and a pressing portion 313 , wherein the hook 311 is located on the buckle 31 On one side, the pressing portion 313 is located on the other side opposite to the side where the buckle 31 is located.

As shown in FIG. 2B , the engaging member 41 is provided on the surface of the lower housing 4 at a position corresponding to the hook 311 , and at the same time, the engaging member 41 is provided with a slot for interlocking with the hook 311 411. The protruding block 45 is disposed at a position corresponding to the pressing portion 313 of the lower case 4 , and the protruding block 45 will deviate when the lower case 4 is deformed under force. In this embodiment, one end of the engaging member 41 is arranged on the lower case 4, and two sides of the engaging part 41 respectively have gaps 47 separating the lower case 4. When elastically deformed, the engaging member 41 will not deviate along with the deformation of the lower casing 4 . The width of the slot 411 matches the width of the hook 311 .

In a more ideal embodiment, one end of the pressing portion 313 is provided with a first slope surface 315, when the upper casing 3 and the lower casing 4 are combined, the first slope surface 315 and the protrusion 45 pass through the Indirect contact makes the protrusion 45 slide to the pressing part 313 along the first slope surface 315, thereby solving the problem that the pressing part 313 is pressed by the protrusion 45 and cannot be assembled when assembling the upper and lower housings; One end of the hook 311 is provided with a second slope surface 317. When the upper casing 3 and the lower casing 4 are combined, the second slope surface 317 is in line-surface contact with the engaging member 41, so that the locking groove 411 The hook 311 is interlocked with the hook 311 along the second slope surface 317 . In the above, a first slope surface 315 is designed at one end of the pressing portion 313 and a second slope surface 317 is designed at one end of the hook 311 to facilitate the assembly of the upper casing 3 to the lower casing 4 .

As shown in FIG. 2C, the upper case 3 has been covered on the lower case 4. At this time, the hook 311 of the buckle 31 buckles the slot 411 of the buckle 41, and the protrusion 45 abuts against the pressing portion 313 of the buckle 31 .

Please refer to FIG. 3A and FIG. 3B . FIG. 3A and FIG. 3B are schematic views of assembling the buckle structure of the present invention. In this embodiment, when the upper case 3 needs to be fastened to the lower case 4, the first slope surface 315 at one end of the pressing portion 313 is abutted against the protrusion 45 and the second slope surface 315 at one end of the hook 311. The slope surface 317 is close to one end of the engaging member 41, and exerts pressure on the upper housing 3 so that the second slope surface 317 and the engaging member 41 are squeezed. At this time, the engaging member becomes elastic. Deformed and bent to one side for the buckle to slide down, at the same time, because the projection 45 is close to the first slope surface 315 (that is, the projection 45 is in line-surface contact with the first slope surface 315), the projection 45 Sliding occurs relative to the first slope 315 until the protrusion 45 slides out of the first slope 315 . Continue to press down on the upper casing 3, when the hook of the buckle 31 slides down to the position of the slot 411 of the buckle 41, the buckle 41 resumes elastic deformation, so that the slot 411 is fastened on the hook 311 , thereby fastening the upper case 3 to the lower case 4 (as shown in FIG. 2C ). In this embodiment, the engaging member 41 is a structure composed of elastic materials. When the upper and lower housings 3 and 4 are assembled, it will be elastically deformed by being pressed against the second slope surface 317 of the hook 31, so that the The hook 31 slides to the slot 411 and restores to its original shape. In a more ideal embodiment, in order to reduce weight, the buckle 31, the buckle 41 and the protrusion 45 are made of plastic materials, but the materials used to form the above structure are not limited to this .

Referring to Fig. 2C again, when an external force F is applied to the force-receiving part 43 of the lower casing 4, the lower casing 4 will be elastically deformed by the external force (that is, deflect in the direction of the force), and the protrusion 45 It is provided on the lower housing 4 and connected with the force-receiving part 43. When the force-receiving part 43 is deformed, the protrusion 45 will deviate with the deformation (that is, it is consistent with the direction of force application), and at the same time, the card One end of the engaging part 41 is arranged on the lower case 4, and also shifts following the deformation of the lower case 4. In this embodiment, both sides of the engaging part 41 are separated from the lower case 4 ( 2B circled part), so when the lower housing 4 is deformed under force, the offset distance of the engaging member 41 is smaller than the offset distance of the protrusion 45, and because the protrusion 45 Close to the pressing part 313 of the buckle 31, when the protrusion 45 deviates, it will push the buckle 31, forcing the buckle 31 to deflect together, which makes the above-mentioned lower case When the body 4 is deformed by an external force, the hook 311 of the buckle 31 is always fastened to the slot 411 of the buckle 41, that is, the upper and lower shells will not be unhooked under the action of an external force within a certain range. phenomenon, therefore, the buckle structure with anti-unhooking function of the present invention solves the existing problem of easy unhooking.
