Description

Technical Field

[0001] The utility model relates to the technical field of computers, in particular to a portable computer. Background Art

[0002] In this era of booming information technology, portable computers have become an indispensable tool in modern people's lives and work. Their versatility and portability have led to their widespread application in various fields. With the continuous development of technology and the continuous improvement of user requirements, the design and manufacture of portable computers pay more and more attention to user experience and product aesthetics.

[0003] The bottom shell of a portable computer is an important part of the portable computer. It not only protects the internal electronic components but also bears the role of supporting the entire device structure. However, since the bottom shell of a portable computer is usually relatively wide, in order to ensure its tight fit with the main body of the portable computer, multiple fastening screws are usually used. Using screws will increase the time and complexity of product assembly, thereby affecting production efficiency and increasing production costs; moreover, the fastening and removal of screws are relatively cumbersome, resulting in inconvenience in product maintenance; in addition, if the screws on the bottom shell are loose or fall off, it may cause the bottom shell to deform or internal components to be damaged, affecting the user experience of the product. Considering from the appearance of the product, screws may also affect the overall aesthetics of the portable computer. Although screws are usually hidden under the bottom shell, their existence will still increase the thickness and weight of the bottom shell, thereby affecting the thin and light design of the portable computer.

[0004] To solve these problems, manufacturers are exploring more advanced fixing technologies, such as using fewer screws or adopting a screwless design. For example, some high-end portable computers have begun to adopt a magnetic bottom shell, and users can simply snap to fix or remove the bottom shell, greatly simplifying the assembly and maintenance process; in addition, some manufacturers are also researching other fixing methods such as adhesives or snaps to reduce the dependence on screws. While improving convenience by adopting other bottom shell fixing methods, it is also necessary to consider the stability of the fixing and product costs. Summary of the Invention

[0029] To further elaborate on the technical means and effects adopted by the present utility model, the following provides a detailed description in conjunction with the preferred embodiments of the present utility model and their accompanying drawings.

[0030] Please refer to Figures 1 - 10, the present utility model provides a portable computer, including a main body 1 and a bottom case 2. The bottom case 2 is fixed on the main body 1 through several docking buckle combinations 3 and one self-locking elastic switch 4. Each docking buckle combination 3 includes a first buckle 31 and a second buckle 32 that can be docked and engaged with each other. The first buckle 31 is respectively arranged on the inner surface edge of the bottom case 2, and the second buckle 32 is respectively arranged on the main body 1. The self-locking elastic switch 4 includes a pressing module 41 arranged in the central area of the inner surface of the bottom case 2 and a self-locking module 42 correspondingly arranged on the main body 1.

[0031] When installing the bottom case 2, first engage the first buckle 31 and the second buckle 32 to fix the bottom case 2 on the main body 1, and then press the bottom case 2 to press the pressing module 41 into the self-locking module 42 to achieve self-locking of the bottom case 2.

[0032] When disassembling the bottom case 2, press the bottom case 2 to make the self-locking elastic switch pop open; then use a disassembly tool to gently pry open the docking buckle combination 3 on the inner surface edge of the bottom case 2 to complete the disassembly of the bottom case 2.

[0033] The portable computer of the present utility model uses docking buckle combinations and self-locking elastic switches to replace screws for fixing the bottom case. Utilizing the elasticity of the bottom case itself, the buckles around the bottom case can be easily installed on the main body. Then, the self-locking elastic switch is used to connect and lock the central part of the bottom case with the central part of the main body, making the central part of the bottom case approach the main body direction, and at the same time generating a force from the center of the bottom case to the center of the main body. Under the action of this central force and the elasticity of the bottom case, the bottom case extends towards the periphery of the bottom case, and at the same time generates a set of forces from the center of the bottom case to the edge of the bottom case. Under the action of this set of forces and the extension of the bottom case, the buckles at the edge of the bottom case cannot pop out, making the bottom case reliably fixed on the main body. The portable computer of the present utility model has a simple structure, is convenient for disassembly and assembly, improves production and assembly efficiency, and is convenient for product maintenance; moreover, compared with the method of using screws to fix the bottom case, the docking buckle combinations and self-locking elastic switches are not arranged on the outer surface of the bottom case, making the appearance of the portable computer of the present application more consistent and more beautiful; in addition, since the space required for the cooperation of the docking buckle combinations and the self-locking elastic switches is smaller, the internal space of the portable computer of the present application is larger, which is conducive to the thin and light design of the portable computer.

[0034] Preferably, the number of the docking buckle combinations 3 ≥ 4.

[0035] The number and distribution of the docking buckle assemblies depend on the appearance shape, size, internal structure, and layout of the portable computer. The buckles are preferably evenly distributed on the edge of the portable computer and then adjusted according to the internal structure and layout of the portable computer, which can ensure the fixing effect of the bottom shell while making full use of the space between the internal structures, improve the space utilization rate inside the portable computer, and facilitate the thinning and lightening of the portable computer. When the size of the portable computer is large, more buckles need to be set to ensure the fixing effect of the bottom shell. When the size of the portable computer is small, fewer buckles can be set to reduce the cost while ensuring the fixing effect of the bottom shell and improving the disassembly and assembly efficiency.

[0036] In a preferred embodiment of the present application, the inner surface of the bottom shell 2 is quadrilateral-like, and the number of the docking buckle assemblies 3 ≥ 4, wherein 4 first buckles 31 are respectively arranged at the four corners of the inner surface of the bottom shell 2, and the second buckles 32 are correspondingly arranged on the body 1 corresponding to the first buckles 31.

[0037] Please refer to Figure 2 , in a preferred embodiment of the present application, the inner surface of the bottom shell 2 is quadrilateral-like, and the number of the docking buckle assemblies 3 is 8, wherein 4 first buckles 31 are respectively arranged at the four corners of the inner surface of the bottom shell 2, and the other 4 first buckles 31 are respectively arranged on the four sides of the inner surface of the bottom shell 2, and 8 second buckles 32 are correspondingly arranged on the body 1 corresponding to the first buckles 31. This design is particularly suitable for portable computers with a relatively large size, which can control the cost while ensuring the fixing effect of the bottom shell and the disassembly and assembly efficiency.

[0039] When installing the bottom case 2, press the bottom case 2 so that the clamping block 411 extends into the space between the two first stepped portions 42111 through the first opening 4221, and the pressing block 412 extends into the lower case 421 through the second opening 4222 to squeeze the sliding block 423, causing the sliding block 423 to move towards the second side wall 4213 until it slides into the docking surface 4111, thereby enabling the sliding block 423 to engage with the clamping block 411. At the same time, the sliding rod 424 slides along the first ramp 421124 to the first convex groove 421122. Stop pressing, and the sliding rod 424 slides into the groove 421121, locking the sliding block 423, thus achieving the self-locking of the bottom case 2. When disassembling the bottom case 2, press the bottom case 2 so that the pressing block 412 pushes the sliding block 423 to continue moving towards the second side wall 4213, thereby squeezing the return spring 425. At the same time, the sliding rod 424 slides to the second convex groove 421123 to release the locking state of the sliding block 423. Stop pressing, and under the action of the return spring 425, the sliding block 423 moves towards the third side wall 4214, thus leaving the docking surface 4111, and the pressing module 41 is released from the self-locking module 42, thereby separating the bottom case 2 from the body 1.

[0040] Preferably, the number of the return springs 425 is two. Two first spring seats 42131 are provided on the second side wall 4213, and two second spring seats 4231 are correspondingly provided on the sliding block 423. The return springs 425 are installed between the sliding block 423 and the second side wall 4213 through the first spring seats 42131 and the second spring seats 4231. This design can make the movement of the sliding block 423 more stable.

[0041] Preferably, the two first spring seats 42131 are arranged on both sides of the second side wall 4213.

[0042] Preferably, a second stepped portion 421111 is provided at one end of the end face of the first stepped portion 42111 relative to the upper case 422, which is close to the third side wall 4214, so that the sliding block 423 is restricted between the second stepped portion 421111 and the second side wall 4213. By providing the second stepped portion, there is a gap between the sliding block and the third side wall, making it easier for the pressing block to push the sliding block towards the second side wall.

[0043] Preferably, a baffle 421112 for preventing the return spring 425 from popping out of the first spring seat 42131 is provided on one side of the first stepped portion 42111 close to the second side wall 4213.

This design can further ensure the movement direction of the slider when the pressing block presses the slider, making it easier for the pressing block to push the slider towards the second side wall.

[0046] Preferably, the pressing block 412 and the clamping block 411 are integrally formed. This design can simplify the installation of the pressing module.

[0047] The docking buckle combination and the self-locking elastic switch of the portable computer of the present utility model can also be implemented by other existing technologies.

[0048] In summary, the portable computer of the present utility model uses a docking buckle combination and a self-locking elastic switch to replace the screw for fixing the bottom case. The structure is simple, the disassembly and assembly are convenient, the production and assembly efficiency is improved, and the product maintenance is facilitated; moreover, compared with the method of using screws to fix the bottom case, the docking buckle combination and the self-locking elastic switch are not arranged on the outer surface of the bottom case, making the appearance of the portable computer of the present application more consistent and more beautiful; in addition, since the space required for the cooperation of the docking buckle combination and the self-locking elastic switch is smaller, the internal space of the portable computer of the present application is larger, which is beneficial to the thin and light of the portable computer.
