Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle networking, and in particular relates to a maintainable small TBOX shell of a special two-wheeled vehicle. Background Art

[0002] As an important component of the Internet of Vehicles system, TBOX is currently installed in a large number of new energy vehicles, but the proportion of installation in two-wheeled vehicles, especially special-purpose two-wheeled vehicles such as off-road motorcycles, is not high. For TBOX manufacturers, in order to meet customers' high protection requirements and installation miniaturization requirements, the maintainability and repairability of their existing products are poor. It has become a must to consider how to meet the needs of special two-wheeled vehicle intelligent networking products with acceptable component costs and manufacturing costs, meet the requirements of replaceable and repairable internal components of the equipment, reduce maintenance costs, and meet the national environmental protection recycling regulations for vehicle-mounted equipment.

[0003] Existing solution: The entire machine shell is made of ABS material, and the upper and lower shells are fixed with self-tapping screws.

[0004] Disadvantages of prior art 1:

[0005] 1. The upper and lower shells have a simple structure, and the joint is easily deformed after being fixed, which reduces the dust and water resistance;

[0006] 2. The fixing ability of self-tapping screws decreases after disassembly;

[0007] 4. The existing structure can only meet the high dust and water resistance requirements (IP67) by filling the shell with glue, but the glue filling cannot be completely sealed, and water may still flow into the shell, reducing the service life of the product;

[0008] 5. In the case of glue pouring, the processing and production time required increases, and additional glue pouring and drying equipment is required;

[0009] 6. In the case of glue injection, since the PCBA and the shell are packaged together, the PCBA cannot be repaired and it is also difficult to recycle.

[0010] In order to solve the above problems, a maintainable small TBOX shell for a special two-wheeled vehicle is provided. Utility Model Content

[0011] The utility model provides a maintainable special two-wheeled vehicle small TBOX shell, which aims to meet the problem of replaceable and repairable internal parts of the equipment and reduce maintenance costs. The utility model is implemented as follows: a maintainable special two-wheeled vehicle small TBOX shell includes an upper shell and a lower shell: a plurality of limiting ribs are arranged inside the lower shell, a lower buckle is fixedly connected to the outer wall of the lower shell, a lower mounting block is fixedly connected to the inner wall of the lower shell, a sealing gasket is fitted on the outer wall of the lower shell, and the sealing gasket is a silicone gasket with a hardness of 50°. A connecting line is fixedly connected to the outer wall of the lower shell;

[0012] Wherein, an upper mounting block is fixedly connected to the inner wall of the upper shell, and an embedded nut is fittedly connected to the inner wall of the upper mounting block.

[0013] Preferably, the outer wall of the upper shell is fixedly connected to the upper buckle, and the upper buckle and the lower buckle are used in coordination.

[0014] Preferably, a thread groove is formed on the inner wall of the lower mounting block, and the thread groove passes through the bottom of the lower shell body.

[0015] Preferably, a limit block is provided on the inner wall of the upper shell, and the limit block is used in conjunction with a limit rib plate.

[0016] Preferably, a machine screw is provided at the bottom of the lower shell, and the machine screw passes through the inner wall of the lower mounting block and is threadedly connected to the inner wall of the embedded nut.

[0017] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0018] The limit blocks and limit ribs are used together to reduce the deformation of the shell between the screw fixing points caused by the inward extrusion during fixing or use, thereby preventing the gap between the upper and lower shells from affecting the protection performance; the upper and lower shells are fixed in two ways at the same time, namely, buckles and machine screws + embedded nuts, so as to exert extrusion forces on the silicone sealing ring in both upper and lower directions to meet the IP67 protection standard; the upper buckle and the lower buckle 4 are used together with zero gap to increase the pressure on the sealing gasket and ensure the sealing performance; the machine screws (with waterproof rings) + embedded nuts can be disassembled and assembled repeatedly, and the disassembly and assembly will not affect the fixing performance.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The utility model embodiment provides a maintainable special two-wheeled vehicle small TBOX shell, such as Figure 1-3 As shown, it includes an upper shell 1 and a lower shell 2: a plurality of limiting ribs 6 are arranged inside the lower shell 2, a lower buckle 4 is fixedly connected to the outer wall of the lower shell 2, a lower mounting block 5 is fixedly connected to the inner wall of the lower shell 2, a sealing gasket 7 is fittedly connected to the outer wall of the lower shell 2, and the sealing gasket 7 is a silicone sealing gasket with a hardness of 50°, and a connecting line 3 is fixedly connected to the outer wall of the lower shell 2;

[0026] The inner wall of the upper shell 1 is fixedly connected with an upper mounting block 9, and the inner wall of the upper mounting block 9 is fitted with an embedded nut 8;

[0027] The outer wall of the upper shell 1 is fixedly connected to the upper buckle, and the upper buckle and the lower buckle 4 are used in conjunction with each other;

[0029] The inner wall of the upper shell 1 is provided with a limit block, which is used in conjunction with the limit rib plate 6;

[0030] The bottom of the lower housing 2 is provided with a complete machine screw, which penetrates the inner wall of the lower mounting block 5 and is threadedly connected with the inner wall of the embedded nut 8 .

[0031] It should be noted that, due to the existing solution: the entire housing is made of ABS material, and the upper and lower housings are fixed with self-tapping screws. The disadvantages of the existing technology 1 are: 1. The upper and lower housings have a simple structure, and the joint is easily deformed after being fixed, which reduces the dust and water resistance; 2. The fixing ability of the self-tapping screws decreases after disassembly; 4. The existing structure can only meet the high dust and water resistance requirements IP67 by injecting glue into the housing, but the injection cannot be completely sealed, and water may still flow into the housing, reducing the service life of the product; 5.
