Description

TECHNICAL FIELD

[0001] The utility model relates to sealing technical field especially, relates to integrated module sealing structure and integrated module. BACKGROUND

[0002] Integrated module refers to integrating multiple electronic components or devices into a module to form a relatively independent functional unit. Integrated module can contain multiple different types of elements, such as compressor, liquid tank, heat exchanger, etc., and connect them together to achieve specific functions.

[0003] The sealing ring in the integrated module is crucial in ensuring the sealing, stability and reliability of the module. In the integrated module, whether it is gas, liquid or other medium, the sealing ring can effectively prevent them from leaking out of the interface, gap and other positions of the module, ensuring the normal operation of the system. For example, in the fuel injection integrated module of the automobile engine, the sealing ring can prevent fuel leakage and ensure the sealing and safety of the fuel system. The sealing ring can also isolate different components or areas to prevent different media from mixing or interfering with each other. At the same time, it can also protect the electronic components, mechanical parts and other components inside the integrated module from the erosion of external environmental factors such as dust, moisture, oil stains, etc., prolonging the service life of the module. During the operation of the integrated module, the sealing ring can play a certain buffering and damping role, reducing the friction and collision between components, reducing vibration and noise, and improving the stability and comfort of the module. For example, in some electronic device integrated modules, the sealing ring can reduce component damage or poor contact caused by vibration and other problems.

In other embodiments, the fixing member 5 can be two semicircular rings which are uniformly distributed in the circumferential direction of the second sealing ring 3, or the fixing member 5 can be four sector rings which are uniformly distributed in the circumferential direction of the second sealing ring 3.

[0080] Optionally, the fixing member 5 and the outer wall of the second sealing ring 3 are fixed by extrusion in a forming die to realize the connection of the fixing member 5 and the second sealing ring 3. In other embodiments, the fixing member 5 and the second sealing ring 3 can also be connected by adhesion.

[0081] Optionally, the first connecting member 41 is provided with a third clamping portion 414 which is annular and coaxial with the first through hole 411, the third clamping portion 414 is arranged as a third end face, the second connecting member 42 is provided with a fourth clamping portion 424 which is annular and coaxial with the second through hole 421, the fourth clamping portion 424 is arranged as a fourth end face, and the fixing member 5 is clamped between the third end face and the fourth end face, so that the connection of the fixing member 5 and the first connecting member 41 and the second connecting member 42 is more close, thereby making the sealing effect of the entire integrated module sealing structure better.

[0082] The embodiment also provides an integrated module to solve the problem that the refrigerant leaks at the interface of the integrated module due to poor sealing effect of the integrated module sealing structure during a salt spray test.

[0083] An integrated module includes a first connecting pipe, a second connecting pipe and the integrated module sealing structure, the fixing member 5 is clamped between the third end face and the fourth end face, the inner wall of the fixing member 5 applies a force to the second sealing ring 3 towards the center of the gasket 1, thereby preventing irregular deformation of the second sealing ring 3 in the case that the second sealing ring 3 expands outward under stress during extrusion, reducing the sealing effect, thereby improving the sealing performance of the entire integrated module at the connection between the pipe opening of the first connecting pipe and the pipe opening of the second connecting pipe, thereby preventing refrigerant leakage at the pipe opening connection of the integrated module.

[0084] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is unnecessary and impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
