[0002] A laptop computer is a small, portable personal computer whose core features include portability, integrated design, and versatility. The casing assembly is a key step in laptop manufacturing, which requires consideration of structural strength, heat dissipation performance, and aesthetic appearance.
[0003] In the existing technology, the assembly of the shell requires splicing and screw fixing processes. The bottom shell and the frame need to be pressed and spliced so that the pre-set fixing buckles on their intersecting surfaces can engage and position each other. Then, screws are used to fix the bottom shell and the frame with threaded posts and threaded holes.
[0004] In current technology, the pre-set buckles between the shell and the frame can only be fastened and fixed under a certain pressure. Moreover, the number and position of these buckles vary depending on the laptop model. When there are many buckles, pressing them one by one to fix them is inefficient, which in turn affects the overall assembly efficiency of the laptop.
[0005] Therefore, a quick-connect structure for the casing of a laptop computer is proposed to address the above problems. Utility Model Content
[0006] To address the shortcomings of existing technologies and solve the problem that the pre-set buckles between the shell and frame require a certain amount of pressure to be fastened and fixed, and that the number and location of these buckles vary depending on the laptop model, and that pressing and fixing them one by one when there are many buckles is inefficient, thus affecting the overall assembly efficiency of the laptop, a quick-fastening structure for the laptop shell is proposed.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The quick-connect structure for the outer shell of a laptop computer, as described in this utility model, includes a fastening base, a support plate installed at the top center of the fastening base, and U-shaped snap fastener plates symmetrically installed on both sides of the fastening base. The bottom surface of the U-shaped snap fastener plate is parallel to the top surface of the support plate. Two snap fastener connecting plates are installed on the side walls of both ends of the U-shaped snap fastener plate through a pivot. The center lines of the two snap fastener connecting plates are parallel to each other. A snap-fit pivot is fixedly connected to the center of one end of the two snap fastener connecting plates near the fastening base. The snap-fit pivot is snapped into a circular groove on the side wall of the fastening base.
[0008] Preferably, the U-shaped snap-fit plate has snap-fit openings on multiple side walls, and snap-fit blocks are slidably installed between the inner walls of the multiple snap-fit openings, with the bottom surface of the protrusion at one end of the snap-fit block located below the bottom surface of the U-shaped snap-fit plate.
[0009] Preferably, a limiting pin is fitted between the snap-fit block and the straight groove through hole of the U-shaped snap-fit plate.
[0010] Preferably, a pressure plate mounting groove is provided at the center of both sides of the fastening base, and a deflecting pressure plate is installed inside the two pressure plate mounting grooves through a rotating shaft.
[0011] Preferably, the deflection plate has a straight groove opening on its side wall, and a linkage rod is slidably engaged between the inner walls of the straight groove opening.
[0012] Preferably, two limiting rings are symmetrically fixed to the outer wall of the linkage rod near the center, and the adjacent side walls of the two limiting rings are respectively in contact with the two sides of the outer wall of the deflection pressure plate.
[0013] Preferably, both ends of the linkage rod are slidably fitted with rod sleeves, and a linkage shaft is fixedly connected to the center of the outer wall of the rod sleeve. The linkage shaft is engaged in the circular groove on the side wall of the snap-fit connecting plate.
[0014] Preferably, inclined limiting blocks are symmetrically fixed to the two side walls of the snap-fit base, and the inclined surface of the inclined limiting block is close to the side wall of the snap-fit connecting plate.
[0015] The beneficial effects of this utility model are:
[0016] I. In this utility model, the bottom shell is placed on the support plate on the snap-fit base, and the frame is placed on top of the bottom shell after the bottom shell is placed. At the same time, the buckles of the bottom shell and the frame correspond to each other. Then, the deflection pressure plate is pressed as a whole. The U-shaped snap-fit plate and the frame component contact and press the structure. Under the cooperation of the linkage rod and the snap-fit connecting plate, pressure is applied to the snap-fit between the bottom shell and the frame. The method of pressing the frame top with the U-shaped snap-fit plates on both sides at the same time replaces the process of pressing it one by one, realizing the device to quickly snap the laptop shell, thereby increasing the work efficiency in the laptop shell assembly process.
[0017] Second, in this utility model, the snap-fit blocks, which are installed in the snap-fit opening, move along with the U-shaped snap-fit plate as a whole. At the same time, they can flexibly press the frame through their flexible bottom surface, preventing the device from causing additional damage to the casing during the installation and assembly of the laptop casing. Furthermore, with the cooperation of the limiting pin, the relative position and specific number of the snap-fit blocks in the snap-fit opening can be changed within a certain range, allowing the device to be adjusted accordingly within a certain range based on the number and position of the snap-fits on the laptop casing, thereby increasing the practicality of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Specific implementation examples are given below.
[0027] Please see Figure 1 - Figure 4This utility model provides a quick-connect structure for a laptop computer casing, including a fastening base 1. A support plate 11 is installed at the top center of the fastening base 1. U-shaped snap-fit plates 2 are symmetrically installed on both sides of the fastening base 1. The bottom surface of the U-shaped snap-fit plates 2 is parallel to the top surface of the support plate 11. Two snap-fit connecting plates 3 are installed on the side walls of both ends of the U-shaped snap-fit plates 2 via pivots. The center lines of the two snap-fit connecting plates are parallel to each other. A snap-fit pivot 31 is fixedly connected to the center of one end of the two snap-fit connecting plates 3 near the fastening base 1. The mounting hinge 31 is mounted in the circular groove on the side wall of the snap-fit base 1. When assembling the laptop shell, the bottom shell is first placed on the support plate 11. Then, the frame's buckles are aligned with the bottom shell's buckles and placed on the bottom shell. The snap-fit connecting plate 3 is mounted on the side wall of the snap-fit base 1 via the mounting hinge 31. The U-shaped snap-fit plate 2, which is horizontally mounted on the snap-fit base 1 via the snap-fit connecting plate 3, can be deflected and pressed down by shaking the snap-fit connecting plate 3, thereby applying snap-fit pressure to the bottom shell and the frame.
[0028] like Figure 3 As shown, the U-shaped snap-fit plate 2 has snap-fit openings 21 on multiple side walls. Snap-fit blocks 4 are slidably installed between the inner walls of the multiple snap-fit openings 21. The bottom surface of the protrusion at one end of the snap-fit block 4 is located below the bottom surface of the U-shaped snap-fit plate 2. A limiting pin 5 is snapped between the snap-fit block 4 and the straight groove through hole of the U-shaped snap-fit plate 2. The snap-fit block 4 is installed on the side wall of the U-shaped snap-fit plate 2 through the snap-fit openings 21, allowing the snap-fit block 4 to deflect and press down along with the U-shaped snap-fit plate 2 as a whole. The snap-fit block 4 is made of flexible material, so its bottom surface will not cause additional damage to the frame during the contact with the frame and the application of downward pressure. Furthermore, with the cooperation of the limiting pin 5, the relative position and specific number of the snap-fit blocks 4 within the snap-fit openings 21 can be changed within a certain range, allowing the device to be adjusted accordingly within a certain range based on the number and position of the snaps on the laptop casing.
[0029] like Figure 1 , Figure 2 and Figure 4As shown, pressure plate mounting grooves 12 are provided at the center of both sides of the fastening base 1. Deflecting pressure plates 6 are mounted inside each of the two pressure plate mounting grooves 12 via rotating shafts. Straight groove openings 61 are provided on the side walls of the deflecting pressure plates 6. Linkage rods 7 are slidably fitted between the inner walls of the straight groove openings 61. Two limiting rings 71 are symmetrically fixed to the outer wall of the linkage rod 7 near its center. The adjacent side walls of the two limiting rings 71 contact the outer walls of the deflecting pressure plates 6 on both sides. Straight rod sleeves 8 are slidably fitted onto the outer walls of both ends of the linkage rod 7. A linkage rotating shaft 81 is fixed to the center of the outer wall of the straight rod sleeve 8. The linkage shaft 81 is fitted into the circular groove on the side wall of the snap fastener plate 3. The deflection plate 6, which is hinged in the pressure plate mounting groove 12, can rotate around the shaft. The linkage rod 7 is slidably restricted inside the straight groove opening 61 under the cooperation of the limiting ring 71. At the same time, the straight rod sleeve 8, which is fitted on its outer wall, can engage with the circular groove on the side wall of the snap fastener plate 3 through the linkage shaft 81 on its outer wall. This allows the two U-shaped snap fastener plates 2 to apply downward pressure to the frame under the synchronous and opposite deflection action of the snap fastener plates 3 at both ends during the process of pressing down the deflection plates 6 on both sides, so as to achieve rapid assembly of the laptop shell.
[0030] like Figure 1 and Figure 2 As shown, inclined limit blocks 13 are symmetrically fixed to the two side walls of the snap-fit base 1. The inclined surface of the inclined limit block 13 is close to the side wall of the snap-fit connecting plate 3. The inclined limit block 13 can restrict the flipping of the snap-fit connecting plate 3, preventing the snap-fit connecting plate 3 from excessively deflecting and causing the snap-fit connecting plate 3 to disengage from the linkage rod 7 and the straight rod sliding sleeve 8, thereby increasing the rationality of the device structure.
[0031] Working principle: When assembling the laptop casing, the bottom shell is first placed on the support plate 11. Then, the frame's clips are aligned with the bottom shell clips and placed on the bottom shell. The snap-fit connecting plate 3 is snapped onto the side wall of the snap-fit base 1 via the snap-fit pivot 31. The U-shaped snap-fit plate 2, which is horizontally mounted on the snap-fit base 1 via the snap-fit connecting plate 3, can be deflected and pressed down by shaking the snap-fit connecting plate 3, thereby applying snap-fit pressure to the bottom shell and the frame. The snap-fit block 4 is installed through the snap-fit opening 21 on the side wall of the U-shaped snap-fit plate 2. The snap-fit block 4 can deflect and press down along with the U-shaped snap-fit plate 2. The snap-fit block 4 is made of flexible material, and its bottom surface will not cause additional damage to the frame during the contact with the frame and the application of downward pressure. Furthermore, with the cooperation of the limit pin 5, the snap-fit block 4 is within the snap-fit opening 21. The relative positions and specific quantities can be changed within a certain range, allowing the device to be adjusted accordingly within a certain range based on the number and position of the clips on the laptop casing. The deflecting pressure plate 6, which is hinged in the pressure plate mounting groove 12, can rotate around its axis. Meanwhile, the linkage rod 7, under the cooperation of the limiting ring 71, is slidably restricted inside the straight groove opening 61. At the same time, the straight rod sleeve 8, which is fitted on its outer wall, can engage with the side wall groove of the snap fastener connecting plate 3 through its outer wall linkage pivot 81. This allows the two U-shaped snap fastener plates 2 to apply downward pressure to the frame under the synchronous and opposite deflection action of the snap fastener connecting plates 3 at both ends during the process of pressing down the deflecting pressure plates 6 on both sides, so as to achieve rapid assembly of the laptop casing. The inclined limiting block 13 can restrict the flipping of the snap fastener connecting plate 3 to prevent the snap fastener connecting plate 3 from excessively deflecting, which would cause the linkage rod 7 and straight rod sleeve 8 of the snap fastener connecting plate 3 to detach from each other.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
