It can maintain the internal pressure balance of the engine. When there is exhaust gas pressure in the crankcase, it can be opened to discharge the exhaust gas; it remains closed in the normal state to maintain the negative pressure in the crankcase and prevent oil leakage. It can separate the oil and fuel vapor in the exhaust gas, and filter the waste air in the crankcase to prevent impurities and pollutants from entering the engine. Most engine breathers adopt an open circulation structure, that is, an exhaust pipe connected to the external environment is provided to discharge the exhaust gas.

[0043] The present embodiment provides a respirator outlet pipe assembly, an engine and a vehicle. The vehicle includes a wheel and the engine provided in the present embodiment, and the engine is configured to drive the wheel to rotate. The engine includes an engine body, a respirator and the respirator outlet pipe assembly provided in the present embodiment. The respirator is connected to the engine body, and the respirator outlet pipe assembly can be connected to the respirator and is configured to discharge the exhaust gas of the respirator.

[0044] Figure 1 The structure diagram of the respirator outlet pipe assembly provided by the embodiment of the utility model is shown as follows Figure 1 ; Figure 2 The following is a partial structural diagram of the respirator outlet pipe assembly provided by the embodiment of the utility model. Figure 1 and Figure 2 The respirator air outlet pipe assembly provided in this embodiment includes a bracket 100 and a plurality of pipes that can be sequentially connected to the air outlet of the respirator. In this embodiment, the pipe specifically includes a connecting pipe and an exhaust pipe 200, wherein the connecting pipe is connected between the air outlet of the respirator and the exhaust pipe 200, and the exhaust pipe 200 is connected to the atmosphere so as to discharge the exhaust gas of the respirator. The bracket 100 can be installed outside the engine body, and the exhaust pipe 200 is installed on the bracket 100, and the relative installation angle between the exhaust pipe 200 and the bracket 100 can be adjusted.

[0045] Specifically, the connecting pipeline is a rubber pipe, which is detachably connected to the exhaust pipeline 200. Through the above arrangement, the flexibility of the connecting pipeline can be enhanced, thereby improving the flexibility and versatility of the respirator outlet pipe assembly.

[0046] More specifically, the exhaust port 210 of the exhaust pipe 200 is an oblique cut structure, and the opening direction of the exhaust port 210 can be turned away from the driving direction of the vehicle by adjusting the relative installation angle between the exhaust pipe 200 and the bracket 100. Through the above arrangement, the leeward effect of the exhaust port 210 can be achieved, reducing the risk of icing of the respirator outlet pipe assembly.

[0047] Continue to refer to Figure 1 and Figure 2 , the bracket 100 includes a pipeline connecting portion 110 and an engine connecting portion 120. The exhaust pipeline 200 is installed on the pipeline connecting portion 110. The engine connecting portion 120 is integrally formed at an angle and connected to the pipeline connecting portion 110. In this embodiment, the angle between the engine connecting portion 120 and the pipeline connecting portion 110 is a right angle, and the engine connecting portion 120 is configured to be connected to the outside of the engine body. A connector 220 is provided on the peripheral side of the exhaust pipeline 200, and the connector 220 is detachably connected to the pipeline connecting portion 110. In this embodiment, the connector 220 is a plate-like structure, which is arranged around the peripheral side of the exhaust pipeline 200.

[0048] Specifically, in this embodiment, the engine connection portion 120 can be fixedly connected to the engine body by using the engine connection bolts 130 .

[0049] More specifically, the end of the engine connection part 120 away from the pipeline connection part 110 is bent to form a lap part 121, and the lap part 121 can overlap the boss outside the engine body. The lap part 121 can initially position the engine connection part 120 when assembling the engine connection part 120 and the engine body, improve the convenience of the subsequent installation of the engine connection bolt 130, and can further improve the reliability and stability of the connection between the engine connection part 120 and the engine body.

[0050] More specifically, the pipe connection part 110 is a plate-like structure, and a mounting hole 111 is provided at its geometric center. The exhaust pipe 200 is coaxially arranged in the mounting hole 111, and the connector 220 abuts against and is connected to the upper end surface of the pipe connection part 110. With the mounting hole 111 as the center, a plurality of connecting holes are provided on the pipe connection part 110, and a reliable connection between the connector 220 and the pipe connection part 110 can be achieved by using one-to-one corresponding connecting bolts.

[0051] It should be noted that in order to adaptively reduce the risk of icing of the respirator outlet pipe assembly in different engine arrangements, the exhaust pipe 200 needs to be able to switch between multiple installation states by adjusting the relative installation angle between the connector 220 and the pipe connection part 110. When the exhaust pipe 200 is in different installation states, the opening direction of the exhaust port 210 is different. By adjusting the relative installation angle between the exhaust pipe 200 and the bracket 100, the exhaust port 210 can always be away from the driving direction of the vehicle in various engine arrangements. It should be noted that the relative installation angle between the exhaust pipe 200 and the bracket 100 refers to the degree of rotation of the exhaust pipe 200 at a certain angle relative to its own axis.

[0058] Continue to refer to Figure 1 and Figure 2 The exhaust pipe 200 includes a connecting pipe section 230 and an outlet pipe section 240, and the exhaust port 210 is provided at one end of the outlet pipe section 240 away from the connecting pipe section 230. The connecting pipe section 230 is connected to the connecting pipe, and the connector 220 is disposed on the peripheral side of the connecting pipe section 230. In this embodiment, the connecting pipe section 230 is a steel pipe, and the connector 220 is a steel plate. The two are integrally formed or welded, and the structure is more stable and reliable, and the connection stability between the connector 220 and the pipeline connecting portion 110 can be ensured.

[0059] Specifically, the outlet pipe section 240 is detachably connected to the end of the connecting pipe section 230 away from the connecting pipeline through a clamp 260, which is a rubber pipe. Through the above arrangement, the outlet pipe section 240 and the connecting pipe section 230 are detachably connected, so that the opening direction of the exhaust port 210 can be finely adjusted, and the flexibility of the respirator outlet pipe assembly can be further improved.
