Description

Technical Field

[0001] The present application relates to the field of automobile parts, and in particular to a turbocharger pipe. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller, which presses the air sent from the air filter pipe to enter the cylinder with pressure. In a car or other similar device using turbocharger power, the speed of the turbocharger when working is as high as tens of thousands of revolutions, which will generate a huge air flow in the turbocharger pipeline in a short period of time.

[0003] The following problems still exist in the prior art: when the turbocharger is working, the air passes through the turbocharger pipe quickly to generate a lot of noise. This noise will be transmitted into the car, increasing the decibel value of the noise when the car is driving, affecting the passengers' experience, reducing the ride comfort and the grade of the car, and there is still room for improvement. Utility Model Content

[0004] In order to improve the situation where the noise generated when the fluid in the turbocharger pipe flows is radiated to the engine compartment, generating relatively large radiation noise, the present application provides a turbocharger pipe.

[0005] The turbocharger pipe provided in this application adopts the following technical solution:

[0006] A turbocharger pipe comprises a turbocharger pipe body and a wire spring, wherein the wire spring is sleeved on the outer side wall of the turbocharger pipe body, and the inner ring of the wire spring is pressed against the outer circumferential side wall of the turbocharger pipe body.

[0007] By adopting the above technical solution, the inner ring of the wire spring is pressed against the outer circumferential side wall of the boost pipe, so that when the high-pressure fluid flows, the wire spring can limit the expansion of the turbocharger pipe, thereby reducing the radiation noise of the fluid and improving the overall comfort of the car.

[0008] Optionally, a sheath is sleeved on the boost tube body, an inner circumferential side wall of the sheath abuts against a side of the wire spring away from the boost tube body, and the sheath and the boost tube body are coaxially arranged.

[0009] By adopting the above technical solution, when the sleeve is arranged on the turbocharger pipe, the wire spring abuts against the inner circumferential side wall of the sleeve, so that when the turbocharger pipe expands due to the heat conducted by the fluid, the sleeve limits the thermal expansion of the turbocharger pipe, thereby avoiding friction between the turbocharger pipe and components in the engine compartment of the automobile, increasing the service life of the turbocharger pipe, and further reducing the radiation noise generated by the turbocharger pipe.

[0010] Optionally, a clamp is provided on one side of the boost pipe body, the clamp includes a clamping band and a fastening portion, the fastening portion is fixedly connected to the clamping band, and the clamping band is wound around the outer circumferential side wall of the boost pipe body.

[0011] By adopting the above technical solution, a clamp is installed at one end of the turbocharger pipe. When the turbocharger pipe is connected to the pipe fitting or joint outside the turbocharger pipe body, the clamp is attached to the turbocharger pipe body and connected to the fastening part, and the fastening part is locked, so that it is easy for the operator to tighten after the connection, avoiding the problem of work stagnation due to difficulty in finding a suitable fastening device during operation.

[0012] Optionally, a pad is fixedly connected to one side of the boost tube body, the pad is located at the connection between the boost tube body and the clamp, one side of the pad abuts against the outer circumferential side wall of the boost tube body, and the other side of the pad abuts against the clamp.

[0013] By adopting the above technical solution, when the clamp is tightened, the tightening end is prone to generate greater friction, which causes the friction to damage the turbocharger pipe body and cause greater wear. The provision of the pad improves the situation in which the connection between the turbocharger pipe and the pipe fittings other than the turbocharger pipe body is prone to wear, thereby reducing the tightness, thereby increasing the service life of the turbocharger pipe.

[0014] Optionally, a cable tie is fixedly connected to the boost tube body, the cable tie is sleeved on the outer circumferential side wall of the boost tube body, the cable tie abuts against the outer circumferential side wall of the boost tube body, and a lock buckle is fixedly connected to the cable tie.

[0015] By adopting the above technical solution, by arranging a cable tie fixedly connected with a lock buckle on the turbocharger pipe, the turbocharger pipe can be fixed inside the engine compartment of the car, thereby avoiding the vibration of the turbocharger pipe caused by the vibration of the car during driving, thereby avoiding the problem of collision and wear between the turbocharger pipe and other parts in the engine compartment.

[0016] Optionally, a clamping ring for connecting the boosting tube body and a pipe fitting other than the boosting tube body is sleeved on one side of the boosting tube body away from the clamping hoop, and a limiting plate is integrally provided on the clamping ring. The limiting plate is folded toward the inside of the clamping ring, and the limiting plate abuts against one end of the boosting tube body.

[0017] By adopting the above technical solution and setting a clamping ring, the turbocharger pipe can be connected to the pipe fitting outside the turbocharger pipe body, thereby improving the situation of taking a long time to find a suitable connector when operating the pipe connection, thereby improving the work efficiency of the operator. By setting a limit plate, the clamping ring is fixed on one side of the turbocharger pipe, thereby tightening the clamping ring and preventing it from falling off.

[0018] Optionally, a plurality of clamping holes are opened on the side of the clamping ring away from the boost tube body, the clamping holes are distributed on the outer circumferential side wall of the clamping ring, the clamping hole passes through the clamping ring, and an elastic rod is provided on the clamping ring, the elastic rod comprises a tightening portion, a connecting portion and a driving portion, the tightening portion presses against a pipe fitting other than the boost tube body that passes through the clamping ring, the connecting portion is fixedly connected to two ends of the tightening portion, the connecting portion is clamped in the clamping hole, the driving portion is fixedly connected to an end of the connecting portion on the inner side away from the clamping ring, the driving portion communicates with the connecting portions that pass through two adjacent clamping holes, a force-applying portion is fixedly connected to the elastic rod, the force-applying portion is arranged at two ends of the elastic rod, the force-applying portion is fixedly connected to the driving portion, and when the two force-applying portions are away from each other, the tightening portion of the elastic rod presses against the pipe fitting other than the boost tube body.

[0019] By adopting the above technical solution, an elastic rod and a clamping hole are provided, and the elastic rod is clamped in the clamping hole, so that the pipe fitting outside the boost pipe body can be tightened by the elastic rod when connected with the clamping ring, thereby improving the plug-in efficiency of the clamping ring and the pipe fitting outside the boost pipe body and reducing the difficulty of operation.

[0020] Optionally, a positioning block is provided on the outer circumferential side wall of the clamping ring, and the positioning block is located on the side of the clamping ring away from the boost pipe body. A force groove is opened on the positioning block. When the force-applying part is controlled to be embedded in the force groove, the tightening part presses against the pipe fitting outside the boost pipe body.

[0021] By adopting the above technical solution, a positioning block is arranged on the outer circumferential side wall of the clamping ring. When the force-applying part is embedded in the force-bearing groove, the force-bearing groove limits the movement of the force-applying part, thereby preventing the force-applying parts from approaching each other, causing the elastic rod to expand and lose its fastening effect. The fastening of the pipe fittings connected by the clamping ring except the booster pipe body is improved, and the problem of losing the fastening effect due to slipping of the elastic rod is avoided.

[0022] Optionally, an inner ring is fixedly connected to the clamping ring, the inner ring is located on the inner side of the clamping ring, the boost tube body is sleeved on the outer circumferential side wall of the inner ring, the clamping ring and the inner ring are coaxially arranged, a guide surface is provided on the inner circumferential side wall of the inner ring, the guide surface is located on the side away from the boost tube body, and the guide surface and the inner ring are coaxially arranged.

[0024] Optionally, an annular groove is formed on the inner ring, and a sealing ring is provided on the inner ring, and the sealing ring is embedded in the annular groove.

[0025] By adopting the above technical solution and arranging a sealing ring, the connection between the boost pipe and the pipe fittings other than the boost pipe body is further sealed, thereby strengthening the sealing performance of the overall structure and improving the stability of the turbocharger pipe.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The inner ring of the wire spring is pressed against the outer circumferential side wall of the turbocharger pipe, so that when the high-pressure fluid flows, the wire spring can limit the expansion of the turbocharger pipe, thereby reducing the radiation noise of the fluid and improving the overall comfort of the car when riding;

[0028] 2. When the sheath is placed on the turbocharger pipe, the sheath limits the thermal expansion of the turbocharger pipe, thereby avoiding friction between the turbocharger pipe and components in the engine compartment of the car, increasing the service life of the turbocharger pipe and further reducing the radiation noise generated by the turbocharger pipe;

[0029] 3. By setting a cable tie with a lock fixedly connected to the turbocharger pipe, the turbocharger pipe can be fixed inside the car engine compartment to avoid vibration of the turbocharger pipe due to the vibration of the car during driving, and causing the turbocharger pipe to collide and wear with other parts in the engine compartment.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The present application embodiment discloses a turbocharger pipe. Figure 1 A turbocharger pipe comprises a turbocharger pipe body 1 and a connection assembly 2. The connection assembly 2 is installed at both ends of the turbocharger pipe body 1 so that the turbocharger pipe body 1 is connected to a pipe fitting other than the turbocharger pipe body 1.

[0037] Reference Figure 1 The connection assembly 2 includes a clamp 21. The clamp 21 includes a clip 211 and a fastening portion 212, and the fastening portion 212 is fixedly connected to the clip 211. The clip 211 is wound around the outer circumferential side wall of the boost pipe body 1, so that the clip 211 fits the boost pipe body 1. When the end of the clip 211 away from the fastening portion 212 passes around the boost pipe body 1 and is passed through the fastening portion 212, the fastening portion 212 is adjusted, so that the clip 211 is gradually locked to fix the boost pipe body 1 and the pipe fittings other than the boost pipe body 1 that pass through the boost pipe body 1 are fixed.

[0038] Reference Figure 1 A gasket 11 is also fixedly connected to the outer circumferential side wall of the boost pipe body 1. The gasket 11 is located at the connection between the fastening portion 212 and the boost pipe body 1, so that the fastening portion 212 abuts against the gasket 11, avoiding direct contact between the fastening portion 212 and the boost pipe body 1, thereby reducing the wear of the boost pipe body 1 when the clamp 21 is tightened.

[0039] Reference Figure 1, a wire spring 3 is sleeved on the outer circumferential side wall of the boost tube body 1, and the inner ring of the wire spring 3 is pressed against the outer circumferential side wall of the boost tube body 1. The wire spring 3 is arranged along the length direction of the boost tube body 1, so that the wire spring 3 fully contacts the boost tube body 1. A sheath 4 is sleeved on the boost tube body 1, so that the sheath 4 protects the boost tube body 1 from collision and wear. The sheath 4 and the boost tube body 1 are coaxially arranged, and the inner circumferential side wall of the sheath 4 is pressed against the outer ring of the wire spring 3. A cable tie 5 is fixedly connected to the boost tube body 1, and the belt body 51 of the cable tie 5 is wound around the outer circumferential side wall of the boost tube body 1, and the belt body 51 is pressed against the outer circumferential side wall of the boost tube body 1. A lock buckle 52 is fixedly connected to the cable tie 5, so that the boost tube body 1 can be fixed on other objects. In the embodiment of the present application, the cable tie 5 can be located on a side close to the clamp 21, or on a side away from the clamp 21, or can be set in the middle section of the boost pipe body 1, depending on specific needs.

[0040] Reference Figure 2 and Figure 3 , the connection assembly 2 also includes a clamping ring 22. The clamping ring 22 includes a limit plate 221, a fastening assembly 222 and an inner ring 224. The limit plate 221 is integrally arranged on the clamping ring 22, and the limit plate 221 is bent toward the inner side of the clamping ring 22. When the clamping ring 22 is sleeved on the outer circumferential side wall of the boosting pipe body 1, one side of the limit plate 221 abuts against one side of the boosting pipe body 1, so that the limit plate 221 limits the movement of the boosting pipe body 1, and prevents the boosting pipe body 1 from being separated from the clamping ring 22, so that the clamping ring 22 loses the connection function of connecting the boosting pipe body 1 and the pipe fittings other than the boosting pipe body 1.

[0041] Reference Figure 3 and Figure 4The fastening assembly 222 includes an elastic rod 2221 and a force-applying portion 2222. The fastening assembly 222 is fixedly connected to the clamping ring 22, so as to fasten the connection between the clamping ring 22 and the pipe fittings other than the boost pipe body 1. A clamping hole 23 is provided on the side of the clamping ring 22 away from the boost pipe body 1, and the elastic rod 2221 is clamped in the clamping hole 23. The elastic rod 2221 includes a tightening portion 22211, a connecting portion 22212 and a driving portion 22213. The tightening portion 22211 is located on the inner side of the clamping ring 22, and the tightening portion 22211 is in contact with the pipe fittings other than the boost pipe body 1, so that the elastic rod 2221 is in contact with the outer circumferential side wall of the pipe fittings other than the boost pipe body 1. The connecting portion 22212 is fixedly connected to the two ends of the abutting portion 22211, the connecting portion 22212 is clamped in the clamping hole 23, and the connecting portion 22212 passes through the clamping hole 23 and extends to the outside of the clamping ring 22. The driving portion 22213 is fixedly connected to two adjacent connecting portions 22212 extending to the outside of the clamping ring 22. The force-applying portion 2222 is fixedly connected to the two ends of the elastic rod 2221. When the two force-applying portions 2222 are controlled to approach each other, the force-applying portion 2222 drives the connecting portion 22212 to move toward the outside of the clamping ring 22 as a whole, so that the abutting portion 22211 on the connecting portion 22212 is released from the abutting state, thereby completing the relaxation and withdrawing the pipe fitting except the booster pipe body 1.

[0042] Reference Figure 3 and Figure 4 , the clamping ring 22 is also clamped with an anti-loosening component 223. The anti-loosening component 223 includes a clamp 2231 and a positioning block 2232. The clamp 2231 is clamped on the clamping ring 22, and the clamp 2231 is provided with a positioning block 2232 on the outer circumferential side wall of the boost pipe body 1. In the embodiment of the present application, the number of the positioning blocks 2232 is two. The clamp 2231 is provided with a protrusion 22311, which makes it easy for the operator to apply force to complete the clamping and plugging action. The clamp 2231 is fixedly connected with a guide head 22312, which points to the clamping direction, making it easy for the operator to identify. The positioning block 2232 is provided with an installation groove 22321 on one side close to the boost pipe body 1. When the elastic rod 2221 is installed, the clamp 2231 is inserted so that the force-applying part 2222 passes through the installation groove 22321 to prevent the positioning block 2232 from bumping against the elastic rod 2221 and causing dislocation. A force groove 22322 is provided on the positioning block 2232. When the force-applying part 2222 is controlled to be embedded in the force groove 22322, the force-applying part 2222 drives the tightening part 22211 on the connecting part 22212 to move toward the inner side of the clamping ring 22, so that the tightening part 22211 is tightened on the pipe fitting except the booster pipe body 1.

[0043] Reference Figure 3 and Figure 4The inner ring 224 is fixedly connected to the inner side of the clamping ring 22. The inner ring 224 and the clamping ring 22 are coaxially arranged. The inner circumferential side wall of the boost pipe body 1 is abutted against the outer circumferential side wall of the inner ring 224, so that the inside of the clamping ring 22 is initially sealed. The inner circumferential side wall of the inner ring 224 has a guide surface 2241. The guide surface 2241 and the inner ring 224 are coaxially arranged, so that when the pipe fittings other than the boost pipe body 1 are inserted into the inner ring 224, the guide surface 2241 guides the pipe fittings other than the boost pipe body 1 to move closer to the center of the inner ring 224. The inner ring 224 also has a sealing ring 2242, and an annular groove 2243 is also formed on the inner ring 224. The sealing ring 2242 is embedded in the annular groove 2243, so that when the pipe fittings other than the boost pipe body 1 are inserted into the clamping ring 22, the pipe fittings other than the boost pipe body 1 abut against the side of the sealing ring 2242 away from the boost pipe body 1, further improving the overall sealing performance. When the sealing ring 2242 is embedded in the annular groove 2243, there is a reserved space on the side of the sealing ring 2242 close to the boost pipe body 1, so that the impact force of the buffer fluid on the boost pipe body 1 and the pipe fittings other than the boost pipe body 1 can be reduced.

[0044] The implementation principle of a turbocharger pipe in an embodiment of the present application is as follows: the booster pipe body 1 is sleeved on the pipe fittings other than the booster pipe body 1, and then the fastening part 212 is tightened, so that the clamping belt 211 drives the booster pipe body 1 to shrink toward the axis, and the action of tightening the booster pipe body 1 and the pipe fittings other than the booster pipe body 1 is completed, and the booster pipe body 1 is connected to the pipe fittings other than the booster pipe body 1 through the clamping ring 22, the force applying part 2222 is controlled to be close to each other, and then the pipe fittings other than the booster pipe body 1 are inserted into the clamping ring 22, and the force applying part 2222 is loosened to complete the tightening of the clamping ring 22 and the pipe fittings other than the booster pipe body 1; when the turbocharger is operating, the hot fluid generated passes through the booster pipe body 1, so that the wire spring 3 limits the expansion of the booster pipe body 1, thereby reducing the noise generated by the booster pipe and improving the overall comfort during riding.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
