[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0053] This application proposes a power device 101, Figures 1 to 7 These are some embodiments of the present application.

[0054] See also Figures 1 to 2 In some embodiments of the present application, the power device 101 includes a power structure 1 and a pipeline structure 4. The power structure 1 has a cavity 2. The pipeline structure 4 is connected to the cavity 2 and is used to discharge the gas in the cavity 2.

[0055] In the technical solution of the present application, the cavity 2 of the power structure 1 is connected through the pipeline structure 4 so that the gas in the cavity 2 can be discharged, thereby balancing the internal and external air pressures of the power structure 1; compared with the technical solution in the related art in which air holes are provided in the power assembly to balance the internal and external air pressures of the power assembly, the setting of the pipeline structure 4 in the embodiment of the present application enables the power structure 1 to achieve the balance of the internal and external air pressures of the power structure 1 without the need for air holes, thereby avoiding the possible overheating risks and water ingress hazards of the power structure 1, thereby ensuring the performance of the entire vehicle and driving safety.

[0056] The internal and external air pressures of the power structure 1 refer to the air pressure in the cavity 2 of the power structure 1 and the external environmental pressure of the power structure 1 .

[0057] It should be noted that there is no limitation on the form in which the pipeline structure 4 is connected to the cavity 2. An independent pipeline may be provided in the pipeline structure 4 to connect to the cavity 2, or a pipeline connected to the cavity 2 may be provided on the physical structure in the pipeline structure 4.

[0058] In some embodiments of the present application, the power unit 101 also includes an air filter, which is used to communicate with the air intake of the engine 12; the pipeline structure 4 is also connected to the air filter 3, so that the cavity 2 is connected to the air filter 3 through the pipeline structure 4; in this embodiment, the air filter 3 is reused as a debris removal element of the pipeline structure 4, so that both ends of the pipeline structure 4 will not be exposed to the external environment, thereby preventing liquid from invading the cavity 2 of the power structure 1 from the pipeline structure 4 or impurities from clogging the pipeline structure 4, thereby ensuring the performance of the entire vehicle and driving safety.

[0059] Among them, the main function of the air filter 3 is to intercept impurities such as dust, gravel, pollen, metal particles in the air, and prevent them from entering the interior of the engine 12 with the intake air, so as to ensure the combustion efficiency and performance of the engine 12 and extend the service life of the engine 12; at the same time, the air filter 3 has a certain water-blocking ability, so the pipeline structure 4 is connected to the air filter 3, so that impurities and liquids cannot enter the pipeline structure 4.

[0060] Compared with the related art, the method of connecting the air filter 3 and the cavity 2 of the power structure 1 through the pipe structure 4 means that the power structure 1 does not need to be provided with air holes. The pipe structure 4 can directly connect the cavity 2 and another cavity, and thus there is no risk of water ingress.

[0061] The other cavity refers to the cavity portion in the air filter 3 where liquid and impurities cannot enter; or the cavity between the air filter 3 and the engine 12. When air enters the cavity between the air filter 3 and the engine 12, impurities and water will be removed by the air filter 3.

[0062] The air filter 3 is unidirectional and is arranged at the air intake of the engine 12, so that air enters the engine 12 through the air filter 3. In fact, the air filter 3 is connected to the external environment, and is connected to the cavity 2 and the air filter 3 through the pipe structure 4, that is, the cavity 2 is connected to the external environment through the pipe structure 4 and the air filter 3 in turn; during the operation of the power structure 1, the temperature of the cavity 2 inside the power structure 1 increases and the pressure increases. The setting of the pipe structure 4 can discharge the high-pressure gas in the cavity 2 inside the power structure 1. At this time, the engine 12 takes in air, and the gas discharged from the power structure 1 can directly enter the engine 12, thereby achieving internal and external air pressure balance of the power structure 1 during operation, so as to avoid damage or oil leakage of the oil seal or gasket due to the internal and external pressure difference during operation of the power structure 1.

[0063] Of course, since the pipeline structure 4 and the air filter 3 connect the external environment with the cavity 2, if the cavity 2 inside the power structure 1 is in a negative pressure environment, the gas in the external environment can also pass through the air filter 3 and the pipeline structure 4 in turn into the cavity 2 to balance the internal and external air pressure of the power structure 1.

[0064] It should be noted that the air filter 3 includes an inlet and an outlet. After the air enters through the inlet of the air filter 3, it is discharged from the outlet of the air filter 3 to the interior of the engine 12, that is, the gas discharged from the outlet of the air filter 3 does not contain liquid or impurities; therefore, in this embodiment, the pipeline structure 4 is connected to the outlet of the air filter 3, that is, the gas in the cavity 2 is discharged to the engine 12 via the pipeline structure 4.

[0065] There is no limitation on the type of the power structure 1, such as an engine 12, a gearbox, a motor 13, etc.; at the same time, the power structure 1 can also be an integration of different drive elements or transmission elements.

[0067] Compared with integrating the pipeline 41 into the power structure 1 , the arrangement of the pipeline 41 in the above embodiment can effectively improve the convenience of maintaining the pipeline 41 .

[0069] Among them, when the power structure 1 is working, a small amount of impurities or pollutants may be discharged from the pipeline structure 4. The filter part 42 can filter the impurities or pollutants discharged by the power structure 1 to prevent the impurities or pollutants discharged by the power structure 1 from invading the air filter 3 or entering the interior of the engine 12 from the air filter 3, thereby improving the safety of vehicle driving.

[0070] There is no limitation on the location of the filter unit 42 , such as being located inside the pipe 41 or at one end of the pipe 41 ; the filter unit 42 can be designed according to actual production requirements.
