[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0023] Refer to Figures 1-4, A multi-functional plastic housing structure, comprising: a housing main body 2, whose upper wall has an opening; a cover plate 1, which is fastened to the opening of the upper wall of the housing main body 2 to enclose the housing main body 2. A receiving cavity for placing components is formed by enclosing the cover plate 1 and the housing main body 2. A locking mechanism, which includes a plurality of latch buttons 101 and lock bodies 204. The plurality of lock bodies 204 are arranged at intervals on the inner circumferential surface of the upper wall of the housing main body 2. The latch buttons 101 and the lock bodies 204 correspond one by one and are snap-fitted. The structural design of the housing main body 2 and the cover plate 1 is optimized. Lock bodies 204 and latch buttons 101 that can be correspondingly engaged are respectively designed in the housing main body 2 and the cover plate 1. After aligning the cover plate 1 with the housing main body 2 and slightly squeezing with force during combination, the lock body 204 and the latch button 101 can be combined together. When disassembling, just pull out with a little force directly. At the same time, the latch buttons 101 and the lock bodies 204 are circumferentially arranged in a plurality, which can also ensure the locking strength at each position, and can achieve fast and stable installation and disassembly, improving the maintainability of the product.
[0024] Among them, the housing main body 2 is preferably in the shape of a cuboid, but is not limited thereto.
[0025] In addition, a handle position can be reserved on the side of the cover plate 1 to facilitate the subsequent disassembly operation of the cover plate 1, or the disassembly operation can also be carried out by using several hollowed-out parts designed on the housing main body 2.
[0026] Furthermore, a limiting block 102 protrudes from the bottom end of the cover plate 1, and a limiting groove 203 adapted for the insertion of the limiting block 102 is formed by sinking on the inner circumferential surface of the upper wall of the housing main body 2. Through the cooperation of the limiting block 102 and the limiting groove 203, the installation position of the cover plate 1 and the housing main body 2 can be assisted in being limited, ensuring the accuracy of the combination of the housing main body 2 and the cover plate 1. At the same time, the limiting groove 203 and the limiting block 102 can also be used as an auxiliary sealing structure to improve the waterproof effect at the connection between the cover plate 1 and the housing main body 2.
[0027] Among them, the size of the housing shell is preferably 150*80*30mm, and the standard size design is adopted, which is convenient for matching and installation with other components. The size of the cover plate is preferably 150*80mm, which perfectly fits the shell to ensure sealing performance and stability. The specific size is not limited herein and can be prefabricated according to the sizes of different electronic components.
[0028] Furthermore, a plurality of latch buttons 101 are circumferentially arranged at intervals along the bottom end of the limiting block 102, and the limiting groove 203 is located above the lock body 204. The advantage of the above design is that through the cooperation of the limiting block 102 and the limiting groove 203, the locking position of the latch button 101 and the lock body 204 can also be assisted in being limited.
[0029] Furthermore, both the housing main body 2 and the cover plate 1 are integrally formed parts. By adopting the integral forming process, while ensuring the strength of the housing main body 2 and the cover plate 1, it can also reduce the manufacturing process and cost.
[0030] Among them, the housing main body 2 and the cover plate 1 are made of high-quality plastic materials, such as modified polypropylene (PP) or polyoxymethylene (POM), etc. There is no limitation here. These materials have good heat resistance, mechanical properties and impact resistance, can maintain stable performance at high temperatures, and meet the usage requirements of electronic products.
[0031] Furthermore, a plurality of triangular reinforcing ribs 202 are circumferentially provided at the connection between the side wall and the bottom wall of the housing main body 2. The bottom end of the limiting block 102 protrudes to form criss-crossing reinforcing ribs 103. Reinforcing rib positions are designed both below the cover plate 1 and inside the housing main body 2. Without affecting the assembly of internal components, it can also enhance the strength and stiffness of the housing, prevent deformation when subjected to external forces, and improve the overall durability.
[0032] Furthermore, the upper end of the lock body 204 is an arc surface 2041. By designing the arc surface 2041, the force required for the lock body 204 to engage with the lock catch 101 can be reduced, facilitating the installation operation for users.
[0033] Furthermore, several windows 201 are provided on the side wall and / or the bottom wall of the housing main body 2. The windows 201 are formed by hollowing out several places on the housing main body. These hollowing designs not only reduce the weight of the housing, but also facilitate the layout and heat dissipation of internal components. The specific number and position of the windows 201 can be designed according to different types of electronic devices.
[0034] In summary, by optimizing the structural design of the housing main body 2 and the cover plate 1, without additional cost, high strength, durability and installation convenience of the housing are achieved, which has significant technical effects and practical value, and is suitable for wide application in various electronic devices.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
