[0031] With the continuous development of the economy, laptop computers are widely used as an office and entertainment tool. When users need to upgrade or replace the parts inside the laptop computer, or disassemble the computer for repair, they need to remove the bottom case of the laptop computer. Since the fixing screws of the bottom case are separated from the bottom case, there may be a problem of screw loss after removing the fixing screws from the laptop computer, which affects the subsequent installation of the bottom case.

[0032] To solve the above problems, the present utility model proposes a bottom case fixing structure 1000, which includes a housing 1, a connecting gasket 2 and a fixing screw 3. The housing 1 includes a first housing 11 and a second housing 12. The first housing 11 is formed with a threaded hole, and the second housing 12 is formed with an installation hole 121 corresponding to the threaded hole; the connecting gasket 2 is arranged between the first housing 11 and the second housing 12, and the connecting gasket 2 is formed with a through hole; the fixing screw 3 includes a head, a columnar section 31 and a threaded section 32 arranged in sequence along the length direction. The threaded section 32 is provided with an external thread. The fixing screw 3 sequentially passes through the installation hole 121 and the through hole of the connecting gasket 2, and the threaded section 32 is screwed with the threaded hole, so that the head of the fixing screw 3 can press the first housing 11 and the second housing 12 to achieve a fixed connection, and the diameter of the threaded section 32 is greater than the width of the through hole.

[0033] The technical solution of the present utility model is to provide a connecting gasket 2 between the first housing 11 and the second housing 12. By sequentially passing the fixing screw 3 through the second housing 12, the connecting gasket 2 and screwing it with the first housing 11, the fixed connection between the first housing 11 and the second housing 12 is realized. And by setting the through-hole size of the connecting gasket 2 smaller than the size of the threaded section 32 of the fixing screw 3, when the fixing screw 3 is removed, the connecting gasket 2 can block and limit the fixing screw 3, so that the fixing screw 3 can still be connected to the second housing 12, avoiding the situation that the fixing screw 3 comes out of the mounting hole 121 and causing the loss of the screw, which improves the convenience of disassembling and assembling the laptop computer.

[0034] In an alternative embodiment, to facilitate the installation of the fixing screw 3, the first housing 11 is formed with a fixing hole 112, and a fixing nut 4 is provided in the fixing hole 112. The threaded section 32 of the fixing screw 3 is screwed with the fixing nut 4. In the actual design process, the connection and fixation between the first housing 11 and the second housing 12 can also be achieved by directly providing internal threads in the fixing hole 112 to cooperate with the external threads of the fixing screw 3. Since the housing 1 of the laptop computer is made of plastic or metal, when the material is plastic, by directly providing internal threads in the fixing hole 112 to cooperate with the fixing screw 3, after the fixing screw 3 is tightened or loosened in the fixing hole 112 for multiple times, the internal threads of the fixing hole 112 may be worn, affecting the cooperation with the fixing screw 3. Therefore, in this embodiment, by installing the fixing nut 4 in the fixing hole 112 and realizing the fixation between the first housing 11 and the second housing 12 through the cooperation of the fixing screw 3 and the fixing nut 4, the connection between the fixing screw 3 and the fixing nut 4 is more reliable, and the service life of both can be guaranteed. The fixing nut 4 can be connected to the fixing hole 112 by means of clamping or bonding to ensure the installation stability. In addition, to ensure the service life of the fixing screw 3 and the fixing nut 4, their materials can be some metals with higher strength, such as copper, stainless steel, etc., which can be specifically selected according to actual needs. In this embodiment, the materials of the fixing screw 3 and the fixing nut 4 are copper, which not only ensures high strength but also has good rust prevention effect, ensuring the connection stability between the first housing 11 and the second housing 12.

[0035] In an alternative embodiment, to avoid the situation that the housing 1 bulges locally when the fixing screw 3 is removed, the first section 41 and the second section 42 of the fixing nut 4 along the length direction are arranged in sequence along the direction close to the second housing 12. The first section 41 is provided with internal threads, and the inner hole width of the second section 42 is larger than the diameter of the threaded section 32. Please refer to Figure 1 and Figure 2, the fixing nut 4 includes a first section 41 provided with internal threads and a second section 42 without threads, and the width of the inner hole of the second section 42 is greater than the diameter of the threaded section 32 of the fixing screw 3. In this way, when the fixing screw 3 is loosened, the second section 42 of the fixing nut 4 can form an avoidance space to accommodate the threaded section 32 of the fixing screw 3. In this way, when disassembling, the second housing 12 will not bulge locally due to the loosening of the fixing screw 3, ensuring the stability of the second housing 12 and avoiding the situation of local deformation of the second housing 12, thereby ensuring the beauty of the notebook computer housing 1. Optionally, the shape of the inner hole of the second section 42 of the fixing nut 4 can be a round hole or a square hole, as long as the width of the hole is greater than the diameter of the threaded section 32 of the fixing screw 3 so that the threaded section 32 can be accommodated in the second section 42. The specific shape can be selected according to the actual situation.

[0036] In an alternative embodiment, to ensure the stability of the fixing screw 3 and the connecting gasket 2 after disassembly, the connecting gasket 2 is bonded to the second housing 12. By bonding the connecting gasket 2 to the second housing 12, since the through-hole size of the connecting gasket 2 is smaller than the size of the threaded section 32 of the fixing screw 3, when the fixing screw 3 is loosened, the fixing screw 3 is still stuck in the connecting gasket 2 due to the restriction of the connecting gasket 2, and the connecting gasket 2 is connected to the second housing 12. In this way, the fixing screw 3 will be clamped in the second housing 12, thus avoiding the situation of screw loss during disassembly and improving the convenience of assembling and disassembling the notebook computer housing 1. Optionally, the connecting gasket 2 can also be clamped in the second housing 12, as long as the stability of the connection between the connecting gasket 2 and the second housing 12 is ensured.

[0037] In an alternative embodiment, to facilitate the installation and positioning of the fixing screw 3, a fixing post 111 is provided on the side of the first housing 11 facing the second housing 12, and a fixing hole 112 is provided at one end of the fixing post 111 close to the second housing 12. In the actual design process, since the first housing 11 and the second housing 12 may not be flat, to connect the first housing 11 and the second housing 12 together, please refer to Figure 1 and Figure 2 , by providing a protruding fixing post 111 on the first housing 11 to make the threaded hole as close as possible to the second housing 12, so as to facilitate the fixing screw 3 to pass through and connect. On the one hand, setting the positioning post can shorten the distance between the connecting parts of the first housing 11 and the second housing 12, thereby shortening the length of the required fixing screw 3. On the other hand, the positioning post also facilitates the user to observe when connecting the first housing 11 and the second housing 12, so as to more easily find the installation position of the fixing screw 3 and facilitate the alignment of the installation hole 121 and the threaded hole, improving the convenience of installing the fixing screw 3.

[0038] Further, to facilitate the accommodation and positioning of the connection gasket 2 when installing the fixing screw 3, the fixing hole 112 is a stepped hole. The fixing hole 112 includes a first stepped hole 1121 and a second stepped hole 1122 that are arranged away from the second housing 12. The fixing nut 4 is arranged in the second stepped hole 1122, and the connection gasket 2 can be accommodated in the first stepped hole 1121. Please refer to Figure 1 and Figure 2 , the fixing hole 112 is arranged in a stepped shape, and the fixing nut 4 is arranged in the second stepped hole 1122 at the bottom. By arranging the first stepped hole 1121 at one end close to the second housing 12, when installing the fixing screw 3, the connection gasket 2 is accommodated in the first stepped hole 1121 under the action of the forces from the second housing 12 and the fixing screw 3. On the one hand, by arranging the connection gasket 2, the contact area between the first housing 11 and the second housing 12 at the connection part can be increased to ensure the stability of their connection. On the other hand, arranging the first stepped hole 1121 can facilitate the accommodation of the connection gasket 2, facilitate reducing the thickness of the connection part, and ensure the stability of the connection gasket 2.

[0039] In an alternative embodiment, to facilitate the fixing screw 3 passing through the connection gasket 2 when installing the fixing screw 3, the connection gasket 2 includes an annular portion 21 and a plurality of limiting portions 22. The plurality of limiting portions 22 are arranged at intervals on the inner edge of the annular portion 21 and enclose to form a through hole. Please refer to Figure 3 , the plurality of limiting portions 22 are arranged at intervals on the inner edge of the annular portion 21, and there is a gap between adjacent two spaced portions. So that when the user passes the fixing screw 3 through the connection gasket 2, one side of the limiting portion 22 is deformed to the other side under the extrusion force of the fixing screw 3, facilitating the threaded section 32 of the fixing screw 3 to pass through the connection gasket 2. When the connection gasket 2 is sleeved on the columnar section 31, the limiting portion 22 can be restored by an external force or self to limit the threaded section 32 to prevent the fixing screw 3 from coming out of the connection gasket 2. Optionally, to facilitate the self - restoration of the connection gasket 2, the connection gasket 2 is an elastic gasket, and the material of the connection gasket 2 is one of rubber and plastic. In this embodiment, to facilitate the self - restoration of the connection gasket 2 after deformation, the material of the connection gasket 2 can be an elastically deformable material such as rubber, resin, plastic, etc., which can be specifically selected according to actual needs.
