[0002] The supercharger oil return pipe is an essential part of the cooling and lubrication system. It is mainly used to return the oil after cooling and lubricating the supercharger to the oil pan at the bottom of the engine for further circulation. At present, most cars have oil return pipes, but due to the harsh working environment of non-road commercial vehicles, the vibration of the engine and its supercharger is usually relatively large. Therefore, the failure rate of the supercharger oil return pipe of non-road commercial vehicles due to vibration is very high. New oil return pipes need to be replaced frequently, which not only delays the normal operation of the engine, but also increases the maintenance cost.
[0003] Therefore, it is urgent to propose a corresponding solution to the problem that the supercharger return oil pipe is prone to cracking due to vibration and needs to be frequently replaced with a new one, which not only delays the normal operation of the engine but also increases the maintenance cost. Utility Model Content

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0030] In order to overcome the problem in the prior art that the supercharger oil return pipe is prone to cracking due to vibration, it is necessary to frequently replace the new oil return pipe, which not only delays the normal operation of the engine, but also increases the maintenance cost. Figure 1 As shown, on one hand, the utility model provides a supercharger oil return pipe, including a plurality of hard pipes 1 and soft pipes 2 connected to each other end to end, wherein the hard pipe 1 includes a middle section hard pipe 12 located in the middle position of the oil return pipe and connected to the soft pipe 2 at both ends, and a fixing clamp 3 for fixing to a fixed structure is installed on the outer peripheral wall of the middle section hard pipe 12, so that the fixing clamp 3 can fix the middle section hard pipe 12 to the fixed structure.
[0031] Specifically, Figure 1 As shown, the hard tubes 1 and the soft tubes 2 are alternately connected, that is, multiple hard tubes 1 are connected together through the soft tubes 2, and both ends of the oil return pipe are hard tubes 1, so as to be connected to the supercharger and oil pan (not shown in the figure) of the engine through the hard tubes 1 to ensure the overall strength of the oil return pipe. Among them, the outer peripheral wall of the middle section hard tube 12 located in the middle position of the oil return pipe can be installed with a fixing clamp 3, which is connected to a fixed structure through the fixing clamp 3, so that the middle section hard tube 12 can be fixed.
[0032] Through the above technical solution, multiple hard tubes 1 and soft tubes 2 are alternately connected. When the engine vibrates violently, the resilience of the soft tube 2 can be used to absorb the vibration energy well, and the vibration intensity of the oil return pipe can be reduced to avoid the oil return pipe from cracking due to vibration. In addition, by installing a fixing clamp 3 on the outer peripheral wall of the middle section hard tube 12 located in the middle position, and fixing the fixing clamp 3 to a fixed structure, the middle section hard tube 12 can be fixed, thereby further reinforcing the oil return pipe in the middle position, reducing the vibration of the oil return pipe, and avoiding the oil return pipe from cracking due to violent vibration, so that there is no need to frequently replace the new oil return pipe, reducing the maintenance cost and increasing the effective working time of the engine.
[0033] Wherein, in some embodiments, combined Figure 1 As shown, the fixing clamp 3 may be a P-type clamp, and / or at least a portion of the rigid tube 1 extends along a non-linear path.
[0034] Specifically, Figure 1 As shown, the fixing clamp 3 can be a P-type clamp, and the P-type clamp can be set on the outer peripheral wall of the middle section of the hard tube 12, and the other end of the P-type clamp is connected to a fixed structure, so that the middle section of the hard tube 12 is fixed and motionless, thereby further reducing the vibration of the return oil pipe, thereby avoiding the overall cracking of the return oil pipe, or the deformation of its hose 2 due to shaking for too long, and at the same time ensuring the working strength of the return oil pipe; and at least part of the return oil pipe can be bent. Such a setting increases the travel path of the engine oil in the return oil pipe. When the car is running, it can block the vibration of the engine oil in the return oil pipe to a certain extent, and can further alleviate the vibration damage of the engine oil vibration to the return oil pipe wall, and can avoid the engine oil directly flowing back to the oil pan and causing the oil pan vibration.
[0035] Wherein, in some embodiments, reference Figure 1 As shown, the hose 2 includes a first hose 21 connected to one end of the middle section hard tube 12 and a second hose 22 connected to the other end of the middle section hard tube 12. The hard tube 1 also includes a front hard tube 11 whose end is connected to the first hose 21 and a rear hard tube 13 whose head end is connected to the second hose 22. The head end of the front hard tube 11 is provided with a supercharger connector for connecting to a supercharger, and the end of the rear hard tube 13 is provided with an oil pan connector for connecting to an oil pan.
[0036] Specifically, combined Figure 1 As shown, the two ends of the middle section hard tube 12 are connected to the first hose 21 and the second hose 22 respectively, wherein the other end of the first hose 21 is connected to the front hard tube 11, and the other end of the second hose 22 is connected to the rear hard tube 13, so that the hard tube 1 and the hose 2 are alternately connected, so as to avoid the oil return pipe as a whole being transported by the hard tube 1. When the engine vibrates, the hard tube 1 is easily damaged and cracked due to the vibration of the oil. Therefore, by alternately connecting the hard hard tube 1 and the hose 2 with resilience, it can be ensured that the oil return pipe will not break and fail under the condition of vibration of the engine, thereby reducing the maintenance cost. In addition, the head end of the front hard tube 11 is provided with a supercharger joint connected to the supercharger (not shown in the figure), and the end of the rear hard tube 13 is provided with an oil pan joint connected to the oil pan (not shown in the figure). By connecting the front hard tube 11 and the rear hard tube 13 to the supercharger and the oil pan, the overall strength of the oil return pipe is guaranteed, and the oil can be ensured to flow into the oil return pipe stably, thereby ensuring the normal circulation operation of the engine cooling and lubrication system.
[0037] In some embodiments, the hard tubes 1 are inserted into adjacent soft tubes 2 , and the hard tubes 1 and the soft tubes 2 are interference fit.
[0038] Specifically, combined Figure 1As shown, the end of each hard tube 1 connected to the adjacent hose 2 is inserted into the tube body of the hose 2. Since the hose 2 has resilience, the connection between the inserted hard tube 1 and the hose 2 can be interference fit, thereby preventing the hard tube 1 and the hose 2 from falling off due to vibration of the return oil pipe when the vehicle travels on an uneven road.
[0039] Furthermore, if Figure 1 As shown, the outer peripheral walls at both ends of the hose 2 are sleeved with clamps 4, and the hard tube 1 and the hose 2 can be fastened and connected by the clamps 4.
[0040] Specifically, the clamp 4 sleeved on the outer wall of the hose 2 can adjust the tightness, so that the hard pipe 1 and the hose 2 can be tightly connected without welding, further avoiding the occurrence of cracks at the connection of the oil return pipe due to vibration. At the same time, by clamping the hard pipe 1 and the hose 2 with the clamp 4, the occurrence of the hose 2 falling off due to vibration during the operation of the engine can be further prevented.
[0041] Wherein, in some embodiments, Figure 1 As shown, the length of each hard tube 1 is greater than the length of each soft tube 2. It is understandable that the soft tube 2 can absorb the energy of the oil vibration, but the strength of the soft tube 2 is insufficient. On the premise of meeting the overall strength of the oil return pipe and avoiding breakage due to vibration, preferably, the length of each hard tube 1 can be greater than the length of each soft tube 2.
[0042] In the present utility model, the "hard tube" refers to a rigid tube, which is a tube that has little or no deformation under the action of force, for example, it can be a steel tube, an aluminum alloy tube, a non-elastic composite material tube, etc.; the "hose" refers to a flexible tube, which can be elastically deformed under the action of force (such as extrusion, stretching, etc.), such as a metal bellows, an elastic composite material tube, etc. Among them, in some embodiments, the hard tube 1 can be a metal pipe, and the hose 2 can be a rubber pipe. Among them, the hose 2 is made of rubber material. When the car travels on an unconventional road and the engine vibrates violently, the rubber hose 2 can well absorb the force generated by the vibration of the oil in the return pipe, so that the oil can flow back to the oil pan smoothly, thereby also avoiding the vibration of the oil pan.
[0043] The second aspect of the utility model provides an engine, which includes the above-mentioned supercharger oil return pipe, wherein the supercharger of the engine is connected to the supercharger joint at the head end of the oil return pipe (i.e., the head end of the front hard pipe 11), and the oil pan of the engine is connected to the oil pan joint at the end of the oil return pipe (i.e., the end of the rear hard pipe 13), so that the oil lubricated by the supercharger can be returned to the oil pan for continuous circulation.
[0044] In some embodiments, the engine may be a diesel engine.
[0045] The third aspect of the utility model provides a vehicle, which includes the above-mentioned engine. The engine and the vehicle both have the above-mentioned supercharger oil return pipe, and the technical effect achieved is the same as that of the supercharger oil return pipe, so it will not be repeated.
[0046] So far, various embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.

It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present disclosure.
