Description

Technical Field

[0001] This utility model relates to the field of automotive engine auxiliary system technology, and in particular to a turbocharger with real-time pressure monitoring function. Background Technology

[0002] A turbocharger is a forced intake device that increases the amount of air entering an engine by driving exhaust gas. It can significantly improve the engine's power and torque. It mainly consists of two parts: a turbine and a compressor. Exhaust gas drives the turbine to rotate and drives the coaxial compressor to compress air. The compressed high-pressure air enters the cylinder to participate in combustion.

[0003] In the actual operation of a turbocharger, real-time monitoring of the pressurized air pressure is crucial for understanding the engine's operating condition and protecting the turbocharger. Most existing pressure sensors are fixed to the exhaust pipe using threaded or flanged connections. This method of fixing restricts the operating space in the narrow engine compartment, making the installation and removal of pressure sensors very cumbersome. Furthermore, under the long-term vibration environment of the vehicle, rigidly connected sensors are prone to loosening or damage due to vibration fatigue. At the same time, most existing turbochargers lack effective pre-filters at the intake end, causing impurities in the air to directly impact the high-speed rotating impeller, accelerating component wear and reducing service life. If a filter is to be installed, the ease of disassembly, cleaning, and maintenance is also a major challenge.

[0004] Therefore, this invention proposes a turbocharger with real-time pressure monitoring function to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems existing in turbochargers, such as the complicated installation and fixing of pressure sensors, the cumbersome disassembly and maintenance in narrow spaces, the lack of a pre-filter at the intake end which makes the impeller easily damaged by impurities, and the difficulty in cleaning and maintaining traditional filter structures, this utility model aims to provide a turbocharger with real-time pressure monitoring function that has an improved structure and can effectively solve the above problems.

[0006] This utility model provides a turbocharger with real-time pressure monitoring function, including: a turbine housing, an intermediate body fixedly connected to the right side of the turbine housing, a compressor housing fixedly connected to the right side of the intermediate body, an inlet and exhaust pipe connected to the top of the turbine housing, a rotary turbine rotatably connected to the inner wall of the turbine housing, a compressor impeller rotatably connected to the inner wall of the compressor housing, an inlet pipe connected to the right side of the compressor housing, and an outlet pipe connected to the front side of the top of the compressor housing.

[0007] The air outlet pipe has a mounting base fixedly connected to the top of the front side of the inner wall. A pressure sensor is slidably connected to the inner wall of the mounting base. Guide sleeves are fixedly connected to the left and right ends of the rear side of the inner wall of the mounting base. A spring is sleeved on the outer wall of the guide sleeve. A rubber pad is fixedly connected to the front end of the spring. A fixed shaft is fixedly connected to the left and right ends of the front side of the mounting base. A limit block is rotatably connected to the outer wall of the fixed shaft. The outer wall of the limit block is engaged in the limit slot opened on the front surface of the mounting base.

[0008] Furthermore, the pressure sensor is confined inside the mounting base, and the elastic resistance provided by the spring and rubber pad, combined with the mechanical blocking effect of the limiting block, enables the pressure sensor to be stably installed and easily removed.

[0009] Preferably, the rubber pad is located between the pressure sensor and the spring, with the front surface of the rubber pad tightly attached to the rear surface of the pressure sensor, and the rear end of the pressure sensor pressing the rubber pad backward to compress the spring.

[0010] Preferably, a filter screen is slidably connected to the inner wall of the intake pipe, and a sealing plug is fixedly connected to the outer wall of the filter screen. The outer wall of the sealing plug is tightly fitted to the inner wall of the intake pipe, and the filter screen covers the cross-section of the inner flow channel of the intake pipe.

[0011] Preferably, a second magnetic ring is fixedly connected to the left side of the inner wall of the air intake pipe, and a first magnetic ring is fixedly connected to the inner wall of the filter screen. The first magnetic ring and the second magnetic ring are connected by magnetic attraction.

[0012] Preferably, the intermediate body has a lubricating oil passage and a cooling water passage inside, and a turbine shaft is rotatably connected inside the intermediate body. The rotating turbine is coaxially and fixedly connected to the compressor impeller through the turbine shaft.

[0013] Preferably, the front end of the guide sleeve passes through the hollow area inside the spring and is inserted into the rear side of the rubber pad, and the outer diameter of the guide sleeve is smaller than the inner diameter of the spring.

[0014] Preferably, the limiting slots are provided on the left and right sides of the front surface of the mounting base, and the limiting block has an L-shaped structure. When the limiting block is rotated to the vertical direction, it is inserted into the limiting slot to prevent the pressure sensor from detaching.

[0015] Preferably, the monitoring mechanism is composed of a mounting base, a pressure sensor, a limit slot, a guide sleeve, a spring, a rubber pad, a fixed shaft, and a limit block.

[0016] Preferably, the filter screen, sealing plug, magnetic ring one, and magnetic ring two are combined to form a pre-filtration mechanism.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of complex installation and fixing methods and cumbersome disassembly and maintenance of turbocharger pressure sensors in the prior art by setting a mounting base structure with a guide spring and a rotation limit block on the inner wall of the exhaust pipe. It achieves the effect of quickly installing and disassembling the pressure sensor without the need for auxiliary tools by pressing and rotating. At the same time, the spring rebound force and rubber pad are used to achieve buffer protection for the sensor, improving the stability and durability of the connection.

[0018] 2. This utility model solves the problems of existing turbocharger inlet lacking pre-filtering device, which easily damages the impeller due to impurities, and traditional filter structures are difficult to clean and maintain, by setting a filter screen structure with magnetic connection and sealing plug in the intake pipe. It achieves the effect of conveniently pulling out the filter screen for cleaning or replacement while ensuring the airtightness of the intake pipe, effectively blocking impurities from entering and extending the service life of the turbocharger.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 6 This utility model provides a turbocharger with real-time pressure monitoring function, which aims to solve the problems of existing turbochargers lacking convenient pressure sensor 22 installation and disassembly structure, and the difficulty in quickly cleaning and maintaining the intake pre-filter device.

[0023] Please refer to Figure 1 and Figure 2 The turbocharger with real-time pressure monitoring includes a turbine housing 1, an intermediate body 10 fixedly connected to the right side of the turbine housing 1, and a compressor housing 6 fixedly connected to the right side of the intermediate body 10. The top of the turbine housing 1 is connected to an exhaust gas inlet pipe 4, which is used to introduce exhaust gas generated by the vehicle. A rotary turbine 5 is rotatably connected to the inner wall of the turbine housing 1, and a compressor impeller 7 is rotatably connected to the inner wall of the compressor housing 6. The intermediate body 10 has a lubricating oil passage and a cooling water passage inside to lubricate and cool the shaft system. A turbine shaft is rotatably connected inside the intermediate body 10. The rotary turbine 5 is coaxially fixedly connected to the compressor impeller 7 through the turbine shaft. When the exhaust gas drives the rotary turbine 5 to rotate, it can drive the compressor impeller 7 to rotate synchronously at high speed through the turbine shaft.

[0024] An air inlet pipe 9 is connected to the right side of the compressor housing 6, and an air outlet pipe 8 is connected to the front top of the compressor housing 6. A mounting base 21 is fixedly connected to the top front side of the inner wall of the air outlet pipe 8. A pressure sensor 22 is slidably connected to the inner wall of the mounting base 21. The pressure sensor 22 is used to monitor the pressure of the compressed air flowing inside the air outlet pipe 8 in real time and convert the pressure signal into an electrical signal for transmission. Guide sleeves 24 are fixedly connected to the left and right ends of the rear side of the inner wall of the mounting base 21. A spring 25 is sleeved on the outer wall of the guide sleeve 24. A rubber pad 26 is fixedly connected to the front end of the spring 25. The rubber pad 26 is located between the pressure sensor 22 and the spring 25. The front surface of the rubber pad 26 is tightly attached to the rear surface of the pressure sensor 22. The front end of the guide sleeve 24 passes through the hollow area inside the spring 25 and is inserted into the rear side of the rubber pad 26. The outer diameter of the guide sleeve 24 is smaller than the inner diameter of the spring 25.

[0025] Fixed shafts 27 are fixedly connected to the left and right ends of the front side of the mounting base 21. Limiting blocks 28 are rotatably connected to the outer wall of the fixed shafts 27. The outer wall of the limiting blocks 28 is engaged with the limiting slots 23 opened on the front surface of the mounting base 21. The limiting slots 23 are opened on the left and right sides of the front surface of the mounting base 21. The mounting base 21, pressure sensor 22, limiting slots 23, guide sleeve 24, spring 25, rubber pad 26, fixed shaft 27 and limiting blocks 28 are combined to form the monitoring mechanism 2. The monitoring mechanism 2 realizes the tool-free and stable installation of the pressure sensor 22 by the elastic resisting force provided by the spring 25 and the mechanical limiting effect of the limiting blocks 28.

[0026] Please refer to Figure 4 A filter screen 31 is slidably connected to the inner wall of the intake pipe 9, and a sealing plug 32 is fixedly connected to the outer wall of the filter screen 31. The outer wall of the sealing plug 32 is tightly fitted to the inner wall of the intake pipe 9. The filter screen 31 covers the cross-section of the inner flow channel of the intake pipe 9 to pre-filter the airflow entering the compressor housing 6. The sealing plug 32 is used to fill the gap between the intake pipe 9 and the filter screen 31 to prevent unfiltered air from bypassing the filter screen 31. A magnetic ring 2 34 is fixedly connected to the left side of the inner wall of the intake pipe 9, and a magnetic ring 1 33 is fixedly connected to the inner wall of the filter screen 31. The magnetic ring 1 33 and the magnetic ring 2 34 are connected by magnetic force. The magnetic attraction between magnetic ring 33 and magnetic ring 34 ensures the axial positioning stability of the filter disc 31 within the intake pipe 9. When the filter disc 31 needs to be replaced or cleaned, it is only necessary to overcome the magnetic attraction between magnetic ring 33 and magnetic ring 34 and the friction between the sealing plug 32 and the inner wall of the intake pipe 9 to slide the filter disc 31 to the right and remove it. The filter disc 31, sealing plug 32, magnetic ring 33, and magnetic ring 34 together constitute the pre-filtration mechanism 3, which ensures that the intake air sealing and filtration effect are guaranteed while greatly simplifying the maintenance of the filter.

[0027] As a preferred embodiment, to enhance the contact stability between the rubber pad 26 and the pressure sensor 22 and to prevent the rubber pad 26 from detaching, please refer to... Figure 5 The rubber pad 26 is located between the pressure sensor 22 and the spring 25. The front surface of the rubber pad 26 is tightly attached to the rear surface of the pressure sensor 22. The rear end of the pressure sensor 22 presses the rubber pad 26 backward and compresses the spring 25. This compression engagement method uses the rebound force of the spring 25 to maintain a tight contact between the pressure sensor 22 and the rubber pad 26, thereby effectively transmitting pressure and absorbing vibration. The front end of the guide sleeve 24 passes through the hollow area inside the spring 25 and is inserted into the rear side of the rubber pad 26. The outer diameter of the guide sleeve 24 is smaller than the inner diameter of the spring 25. By inserting the guide sleeve 24 into the rear side of the rubber pad 26, the lateral displacement of the rubber pad 26 during the force application can be effectively prevented, ensuring that the force transmission direction is always axial.

[0028] As another preferred embodiment, to ensure the reliability of the limiting structure and the ease of operation, please refer to... Figure 6 The limiting slots 23 are provided on the left and right sides of the front surface of the mounting base 21. The limiting block 28 has an L-shaped structure. When the limiting block 28 is rotated to the vertical direction, it is inserted into the limiting slot 23 to prevent the pressure sensor 22 from disengaging. By rotating the limiting block 28 into the limiting slot 23, a mechanical hard limit can be formed to prevent the pressure sensor 22 from accidentally popping out during the working vibration of the turbocharger. At the same time, the L-shaped structure makes it easy for the operator to apply force to rotate it.

[0029] As a further preferred embodiment, in order to improve the main functional structure of the turbocharger, the intermediate body 10 is provided with a lubricating oil passage and a cooling water passage. A turbine shaft is rotatably connected inside the intermediate body 10. The rotating turbine 5 is coaxially and fixedly connected to the compressor impeller 7 through the turbine shaft. The lubricating oil passage is used to provide a lubricating oil film for the bearing system of the turbine shaft, and the cooling water passage is used to remove the heat of the intermediate body 10 and the bearing system under high temperature conditions, so as to ensure that the rotating turbine 5 and the compressor impeller 7 can operate stably at high speed for a long time.

[0030] Working principle: When using a turbocharger with real-time pressure monitoring, the exhaust pipe 4 introduces the exhaust gas generated by the vehicle into the inner wall of the turbine housing 1. The exhaust gas acts on the rotating turbine 5, causing the rotating turbine 5 to rotate at high speed and be discharged from the left side of the turbine housing 1. The rotating turbine 5 drives the compressor impeller 7 to rotate synchronously inside the compressor housing 6 through the turbine shaft. The rotating compressor impeller 7 compresses the air that enters the compressor housing 6 from the intake pipe 9 and discharges it from the outlet pipe 8. The compressed air discharged from the outlet pipe 8 flows through the pressure sensor 22. The pressure sensor 22 monitors the compressed air pressure in real time and converts the pressure signal into an electrical signal, which is then transmitted to the vehicle electronic control unit. When pressure sensor 22 needs to be installed, align pressure sensor 22 with the inner wall of mounting base 21 and insert it. The rear end of pressure sensor 22 squeezes rubber pad 26 and compresses spring 25. Spring 25 deforms and compresses along guide sleeve 24. Guide sleeve 24 guides and prevents spring 25 from deviating. When pressure sensor 22 is fully inside the inner wall of mounting base 21, rotate the limiting block 28 on fixed shaft 27 and engage it in limiting slot 23. Then release pressure sensor 22. Under the action of spring 25's rebound force, pressure sensor 22 moves forward along the inner wall of mounting base 21 and presses against limiting block 28. Limiting block 28 restricts the movement of pressure sensor 22, thereby fixing pressure sensor 22 in the inner wall of mounting base 21, completing the convenient installation of pressure sensor 22. When pressure sensor 22 needs to be inspected, press pressure sensor 22 to move towards the inner wall of mounting base 21, and then rotate limiting block 28 to disengage from the inner wall of limiting slot 23. Pressure sensor 22 can then be removed from the inner wall of mounting base 21 with the assistance of spring 25's rebound force. When air enters through the intake pipe 9, the pre-filter mechanism 3 takes effect. The filter screen 31, which is slidably connected to the inner wall of the intake pipe 9, pre-filters the air entering the compressor housing 6 to intercept impurities. The sealing plug 32 fills the gap between the intake pipe 9 and the filter screen 31 to ensure a tight seal. The filter screen 31 is magnetically connected and fixed to the inner wall of the intake pipe 9 by magnetic ring 33 and magnetic ring 34. When the filter screen 31 is blocked by impurities and needs to be cleaned, the filter screen 31 is pulled out to the right to overcome the magnetic attraction between magnetic ring 33 and magnetic ring 34 and the friction between the sealing plug 32 and the intake pipe 9. The filter screen 31 can then be removed for replacement or cleaning.
