Description

Technical Field

[0001] The utility model relates to the technical field of turbochargers, in particular to a turbocharger protective shell with strong protective performance. 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, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipe to enter the cylinder with pressure. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The increase in air pressure and density can burn more fuel. By increasing the amount of fuel and adjusting the engine speed accordingly, the engine output power can be increased.

[0005] Currently, most turbochargers do not have a strong protective shell on the outside. When the turbocharger is in use, it may be hit by external foreign objects due to the working environment. When it is hit by external impact, the shell cannot buffer and protect the internal parts. The force caused by the impact will be directly transmitted to the internal parts of the shell, which is easy to cause damage to the internal parts of the shell. Utility Model Content

[0028] By providing the snap-fit ​​assembly 5 , the protection strip assembly 3 can be installed and removed by snap-fitting, so that personnel can conveniently replace the arc strip 301 after it is broken.

[0029] See also Figure 4, the card slot 501 is provided on the upper surface of the mounting block 4, the groove 502 is provided on the inner wall of one side of the card slot 501, one end of the spring 503 is fixedly connected to the inner wall of one side of the groove 502, the clamping block 504 is fixedly connected to the other end of the spring 503, the connecting rod 505 is fixedly connected to one side of the clamping block 504, the toggle bar 506 is fixedly connected to one end of the connecting rod 505, the slide groove 507 is provided on the inner wall of the groove 502, the slider 508 is fixedly connected to both sides of the clamping block 504, and is located inside the slide groove 507, one side of the clamping block 504 is an arc surface, and the size is consistent with the clamping groove 304;

[0030] After the arc strip 301 is broken, the toggle strip 506 is pulled outward to drive the clamping block 504 to move through the connecting rod 505, thereby increasing the distance between the clamping block 504 and the clamping groove 304, and disconnecting the clamping relationship, so that the arc strip 301 can be disassembled. The operation is simple and easy to understand.

[0031] See also Figure 1 and Figure 5 Both ends of the supercharger body 1 are fixedly connected with air inlet and outlet 6, the inner wall of the air inlet and outlet 6 is fixedly connected with sound-absorbing cotton 7, the inner wall of one end of the air inlet and outlet 6 is fixedly connected with a mounting ring 8, the inside of the mounting ring 8 is fixedly connected with a grille 9, and one end of the turbine housing 2 is fixedly connected with an exhaust port 10;

[0032] The sound-absorbing cotton 7 and the grille 9 can absorb the noise generated when the turbocharger is working, thereby reducing noise pollution.

[0033] In the utility model, the working principle of the device is as follows:

[0034] When in use, the protection strip assembly 3 is installed on the surface of the turbine housing 2. When the turbine housing 2 is impacted by the outside, the impact force first contacts the rubber energy-absorbing layer 302 to absorb the impact force, and then acts on the arc strip 301, and the arc strip 301 disperses the impact force, so as to buffer and protect the internal parts of the turbocharger. When encountering a larger impact, the impact force breaks the arc strip 301 and finally acts on the polyurethane foam energy-absorbing layer 303. The polyurethane foam energy-absorbing layer 303 absorbs the impact force by relying on the larger deformation of the material itself, blocks the shock wave with extremely strong destructive effect, effectively reduces the impact on the turbocharger, and protects the internal parts of the turbocharger.

[0035] When installing the protection strip assembly 3, the arc strip 301 is sleeved on the surface of the turbine housing 2, and the bottom end of the arc strip 301 is inserted into the card slot 501, so that the bottom end of the arc strip 301 squeezes the card block 504. Since one side of the card block 504 is arc-shaped, it is forced to retract into the card slot 501, and the spring 503 is compressed at the same time. As the bottom end of the arc strip 301 continues to be inserted, the card block 504 and the card slot 304 are located at the same horizontal line. At this time, the groove 502 is reset due to the action of the force, driving the card block 504 to move into the card slot. Once the snap connection is completed inside the connecting groove 304, the arc strip 301 can be installed and fixed. On the contrary, when the arc strip 301 is broken by a large impact and the protective strip assembly 3 needs to be disassembled, it is only necessary to pull the toggle bar 506 outward to drive the snap block 504 to move through the connecting rod 505, so that the distance between the snap block 504 and the snap groove 304 is increased, and the snap connection relationship is disconnected, and the arc strip 301 can be disassembled. When the snap block 504 moves, it can drive the slider 508 to slide in the slide groove 507, making its movement more stable.
