Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive turbocharger pipe structure that is easy to install. Background Technology

[0002] The automotive turbocharging system uses the exhaust gas from the engine to drive the turbine to rotate, thereby increasing the intake air volume. The turbocharger pipe, as a key component connecting the turbocharger and the engine intake system, is responsible for delivering gas with a certain pressure and temperature. The sealing performance and structural strength of the turbocharger pipe connection directly determine the engine's working efficiency and operational stability.

[0003] Existing automotive turbocharger pipe connection structures use flange docking and multiple sets of bolts and nuts for fastening. In the context of the confined space and dense piping in the engine compartment, installers need to simultaneously lift the pipes and align them with multiple bolt holes on the flange. They then need to install the bolts and nuts one by one while their vision is obstructed. This traditional split-type multi-point fastening method not only results in a large number of parts that are difficult to manage, but also prolongs the installation and maintenance time due to the cumbersome hole alignment and tightening operations. It cannot meet the demands of modern automotive maintenance for efficiency and convenience.

[0004] Therefore, this utility model proposes an easy-to-install automotive turbocharger pipe structure to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology, the turbocharger pipe connection structure of automobiles has the problems of difficult hole alignment and cumbersome and time-consuming fastening operations due to the dispersed components in the narrow engine compartment space, resulting in low overall installation efficiency. The present invention aims to provide an improved automobile turbocharger pipe structure that can effectively solve the above problems and is easy to install.

[0006] This utility model provides an easy-to-install automotive turbocharger pipe structure, including: a pipe, and a pressure ring fixedly connected to the connection of the pipe's outer wall; as well as clamp one, clamp two, rotating frame, rotating rod, rotating block, connecting block, threaded sleeve, and threaded rod.

[0007] Among them, clamp one and clamp two can be fitted onto the outer wall of the pressure ring to cover the pipe connection. A rotating frame is fixedly connected to the outer wall of clamp one, and a rotating rod is rotatably connected to the middle of the outer wall of the rotating frame. The end of the rotating rod away from the rotating frame is rotatably connected to the rotating block. The rotating block is fixedly connected to the outer wall of clamp two. The rotating frame and the rotating block are connected in series by the rotating rod to form an openable hinge structure.

[0008] Furthermore, both clamp one and clamp two have a connecting block fixedly connected to their outer bottom ends. A threaded sleeve is fixedly connected to one side of the outer wall of the connecting block. A threaded rod is threadedly connected to the middle of the outer wall of the connecting block. The threaded rod rotates and engages with the inner wall of the threaded sleeve, which can drive the two connecting blocks to move closer to each other.

[0009] Preferably, a sealing groove for accommodating a sealing assembly is provided on the inner side of the outer wall of the pressure ring, and the sealing groove extends continuously along the circumference of the pressure ring to form a closed-loop groove structure.

[0010] Preferably, a sealing ring is provided on the inner wall of the sealing groove, and the shape of the sealing ring is adapted to the shape of the sealing groove to ensure stability after embedding.

[0011] Preferably, the sealing ring is made of corrosion-resistant rubber material with excellent chemical stability, and the sealing ring is clamped between the pressure rings at the ends of the two pipes to fill the connection gap.

[0012] Preferably, both clamp one and clamp two are made of high-strength steel that has undergone reinforcement treatment, and clamp one and clamp two have a semi-circular ring structure to fit the outer circumferential surface of the pressure ring.

[0013] Preferably, the rotating frame is located at the highest point of the outer wall of clamp one, and the rotating block is located at the highest point of the outer wall of clamp two to facilitate the natural suspension of the clamp assembly.

[0014] Preferably, the two connecting blocks are located on opposite sides of clamp one and clamp two, and the threaded rod passes through one of the connecting blocks and is threaded into the threaded sleeve on the other connecting block to achieve a unilateral locking operation.

[0015] Preferably, the threaded sleeve is fixedly connected to the outer wall of the connecting block away from the clamp to provide sufficient thread engagement length.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a clamp assembly with a top rotating hinge structure and a bottom single bolt locking fit, uses a rotating rod to connect the rotating frame and the rotating block, so that the two clamps can be opened and closed conveniently like the jaws of pliers. It solves the problems of limited installation space for turbocharger pipes in narrow engine compartments, easy scattering of parts, and difficulty in hole alignment, which leads to low installation efficiency in the prior art. It achieves the effect of quick insertion and locking without complete disassembly, greatly simplifies the installation process, and prevents the loss of parts, making it easy to install.

[0017] 2. This utility model solves the problems of loosening and leakage at pipe connections due to engine vibration or internal high-pressure gas impact, as well as the easy displacement of seals during installation, by opening a sealing groove on the inner side of the pressure ring at the pipe connection end and embedding a corrosion-resistant sealing ring, and using a clamp assembly made of high-strength steel to forcefully tighten the pressure ring. It achieves the effect of using the sealing groove to limit the position of the sealing ring and enhance the sealing reliability, and ensure that the connection structure maintains excellent airtightness and stability under high temperature and high pressure environment.

[0020] 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.

[0021] Example: Please refer to Figures 1 to 4 This utility model provides an easy-to-install automotive turbocharger pipe structure, aiming to solve the structural defects in the prior art, such as the difficulty in aligning the automotive turbocharger pipe 1 during installation and the difficulty in ensuring the sealing stability after connection.

[0022] Please refer to Figure 1 and Figure 2The easy-to-install automotive turbocharger pipe structure includes a pipe 1, which serves as the main fluid transport channel inside the device. Pressure rings 2 are fixedly connected to the outer walls of the two pipe 1 joints by welding. The pressure rings 2 are used to withstand the radial pressure applied from the outside and transmit it to the pipe 1 joint. A sealing groove 3 is formed on the inner side of the outer wall of the pressure ring 2. The sealing groove 3 extends along the circumference of the pressure ring 2 to form an annular groove. A sealing ring 4, which matches the shape and size of the sealing groove 3, is embedded in the inner wall of the sealing groove 3. The sealing ring 4 is made of corrosion-resistant rubber material with excellent elasticity and chemical stability. The sealing ring 4 is clamped and deformed between the pressure rings 2 at the ends of the two pipe 1s to fill the micro gaps. Thus, through the tight fit between the sealing groove 3 and the sealing ring 4, effective airtight sealing of the joint of the two pipe 1s is achieved.

[0023] Please refer to Figure 3 and Figure 4 To achieve rapid fixation, the automotive turbocharger pipe structure is also equipped with clamp 5 and clamp 9. Both clamp 5 and clamp 9 are made of high-strength steel with excellent tensile strength and weather resistance. Both clamp 5 and clamp 9 are semi-circular ring structures, and when combined, they can cover and fit onto the outer wall of the two pressure rings 2 after they are joined. A rotating frame 6 is fixedly connected to the top of the outer wall of clamp 5 by welding. A rotating rod 7 is rotatably connected to the middle of the outer wall of the rotating frame 6 by a pin or hinge. The end of the rotating rod 7 away from the rotating frame 6 is rotatably connected to a rotating block 8. The rotating block 8 is fixedly connected to the top of the outer wall of clamp 9 by welding. The rotating frame 6 and the rotating block 8 are connected in series by the rotating rod 7, so that clamp 5 and clamp 9 can rotate relative to each other around the axis of the rotating rod 7, thereby realizing the opening and closing operation of the clamp assembly so as to fit onto the outside of the pressure ring 2.

[0024] To lock the clamp assembly, connecting blocks 10 are fixedly connected to the bottom of the outer walls of clamp 5 and clamp 9 by welding. The two connecting blocks 10 are located at the opposite ends of clamp 5 and clamp 9, respectively. A threaded sleeve 11 is fixedly connected to one side of the outer wall of one of the connecting blocks 10. The threaded sleeve 11 is located on the side of the connecting block 10 away from the body of clamp 5 or clamp 9. A through hole is opened in the middle of the outer wall of the connecting block 10 and a threaded rod 12 is inserted through it. The threaded rod 12 passes through one of the connecting blocks 10 and extends into the threaded sleeve 11 on the other connecting block 10 and is threadedly connected to the inner wall of the threaded sleeve 11. By rotating the threaded rod 12 into or out of the threaded sleeve 11, the axial force of the threaded drive drives the two connecting blocks 10 to move closer to each other, thereby causing clamp 5 and clamp 9 to retract inward and clamp the pressure ring 2.

[0025] Please refer to Figure 2 and Figure 4The upper component of the hinged locking mechanism includes a rotating frame 6, a rotating rod 7, and a rotating block 8. The rotating frame 6 has a U-shaped connecting seat structure, and the bottom of the rotating frame 6 is firmly fixed to the top center of the outer wall of the clamp 5 by welding. The upper part of the rotating frame 6 is provided with a pin hole for the rotating rod 7 to pass through. The rotating rod 7, as a connecting pivot, passes through the pin hole of the rotating frame 6 and maintains a rotational fit. The other end of the rotating rod 7 is also connected to the rotating block 8 in a rotational fit manner. The rotating block 8 has a connecting hole adapted to the rotating rod 7 or a hinged lug structure. The bottom of the moving block 8 is fixedly connected to the top center of the outer wall of the second clamp 9 by welding. The rotating frame 6 fixed on the first clamp 5 and the rotating block 8 fixed on the second clamp 9 are connected in series by the rotating rod 7 to form a whole, so that the first clamp 5 and the second clamp 9 can move relative to each other with the rotating rod 7 as the axis. The hinge structure design at the top allows the installer to open the first clamp 5 and the second clamp 9 like opening the jaws of pliers by simply loosening the locking part at the bottom without completely removing the bolts. This greatly facilitates the operation of putting the clamp assembly into or removing the pressure ring 2.

[0026] Meanwhile, the lower component of the hinge-type locking mechanism includes a connecting block 10, a threaded sleeve 11, and a threaded rod 12. The connecting blocks 10 are respectively located on the outer bottom ends of clamp 5 and clamp 9. Each connecting block 10 is fixedly connected to the corresponding clamp body by welding, and the two connecting blocks 10 are arranged face to face when the clamps are closed. The connecting block 10 on the clamp 5 side is provided with a light hole or through hole for the threaded rod 12 to pass through, while the outer side of the connecting block 10 on the clamp 9 side is fixed by welding. A threaded sleeve 11 is fixedly connected. The inner wall of the threaded sleeve 11 is machined with an internal thread that matches the threaded rod 12. One end of the threaded rod 12 is provided with a knob or tool interface for easy operation. The rod of the threaded rod 12 passes through the through hole of the connecting block 10 on the side of clamp 5 and is screwed into the threaded sleeve 11 on the side of clamp 9. This ensures that in the narrow engine compartment space, only one threaded rod 12 needs to be operated to make clamp 5 and clamp 9 tighten inward synchronously and apply a uniform radial clamping force to the pressure ring 2.

[0027] As a preferred embodiment, in order to ensure that the connection of the pipeline 1 still has excellent airtight performance under high temperature and high pressure environment, a sealing groove 3 is specially provided on the inner side of the outer wall of the pressure ring 2. The cross-sectional shape of the sealing groove 3 is rectangular or trapezoidal and is continuously opened along the inner circumference of the pressure ring 2 to form a closed loop structure. The depth and width of the sealing groove 3 are precisely calculated to match the compression of the sealing ring 4. The sealing ring 4 is pre-placed in the sealing groove 3, and the outer diameter of the sealing ring 4 is slightly larger than the bottom diameter of the sealing groove 3 to form an interference fit, preventing the sealing ring 4 from falling off during installation. When the two pressure rings 2 are connected and locked by the external clamp assembly, the sealing ring 4 undergoes elastic deformation under the action of axial pressure and fills the remaining space of the sealing groove 3, thereby effectively blocking the leakage path of the internal high pressure gas.

[0028] As another preferred embodiment, in order to improve the service life and reliability of the sealing component under harsh working conditions, the sealing ring 4 is made of corrosion-resistant rubber material, preferably fluororubber, so that the sealing ring 4 can withstand the erosion of high-temperature exhaust gas or compressed air commonly found in turbocharger systems, and avoid air leakage problems caused by aging and failure of the seal. At the same time, the sealing ring 4 is clamped between the pressure rings 2 at the ends of the two pipes 1, and the rigid support of the pressure rings 2 is used to protect the flexible sealing ring 4 from external mechanical damage.

[0029] As another preferred embodiment, in order to ensure the overall mechanical strength and durability of the connection structure, both clamp 5 and clamp 9 are made of high-strength steel that has undergone heat treatment. This high-strength material gives the clamp assembly extremely high tensile and fatigue resistance, and can withstand the alternating loads generated by engine vibration and internal gas pulsation for a long time without breaking or plastic deformation. In addition, clamp 5 and clamp 9 are both processed into standard semi-circular ring structures, and their inner diameters are precisely matched with the outer diameter of the pressure ring 2, ensuring that the inner wall of the clamp can fit tightly against the outer surface of the pressure ring 2 to achieve the maximum contact area and clamping force.

[0030] As another preferred embodiment, in order to optimize the force distribution of the clamp assembly and facilitate installation, the rotating frame 6 is precisely welded and fixed to the highest point of the top circumference of the outer wall of clamp 1 5, and the corresponding rotating block 8 is also welded and fixed to the highest point of the top circumference of the outer wall of clamp 2 9, so that the center of gravity of the clamp assembly hangs down naturally and can be naturally suspended above the pipe 1 during installation, which makes it convenient for installers to perform the locking operation of the threaded rod 12 from below, and also avoids the interference problems that may be caused by side or bottom hinges.

[0031] As another preferred embodiment, in order to achieve efficient and labor-saving locking operation, the two connecting blocks 10 are welded and fixed to the bottom positions of clamp 1 5 and clamp 2 9 respectively, and the threaded sleeve 11 is arranged on the outer wall of the connecting block 10 away from the clamp body. The threaded rod 12 passes through the through hole of one of the unthreaded connecting blocks 10 and is screwed into the threaded sleeve 11 on the other connecting block 10. This design extends the lever arm of the threaded rod 12 and provides sufficient thread engagement length to ensure that the thread will not strip when locking with high torque. It also provides sufficient operating space for installation tools such as wrenches or electric screwdrivers.

[0032] Working principle: When installing the turbocharger pipeline in a car, the operator first accurately embeds the sealing ring 4 into the sealing groove 3 located inside the pressure ring 2, and brings the ends of the two pipes 1 that need to be connected closer together so that the end faces of the two pressure rings 2 are in close contact. At this time, the highly corrosion-resistant sealing ring 4 is clamped between the two pressure rings 2 and is initially compressed to fill the micro gaps. Then, using the hinge structure at the top, with the rotating rod 7 as the axis, the rotating rod 7 is rotated between the rotating frame 6 and the rotating block 8 to open the clamp 5 and clamp 9 like the jaws of a plier. The opened clamp assembly crosses the pressure ring 2 and covers the outer circumferential surface of the two pressure rings 2 after they are connected. The hinge connection between the rotating frame 6 and the rotating block 8 ensures that the clamp assembly will not fall apart when opened, which greatly facilitates the operation in the narrow space inside the car. After the clamp assembly is positioned and fitted, the operator inserts the threaded rod 12 through the through hole on the connecting block 10 at the bottom of clamp 5, aligns the front end of the threaded rod 12 with the threaded sleeve 11 located on the side of the connecting block 10 at the bottom of clamp 9, and rotates the threaded rod 12 with a wrench or other tools. The threaded rod 12 rotates in the inner wall of the threaded sleeve 11 and generates a huge axial tensile force, pulling the two connecting blocks 10 closer to each other. This causes clamp 5 and clamp 9 to contract towards the center and tightly hold the internal pressure ring 2. The high-strength steel inner walls of clamp 5 and clamp 9 apply uniform and strong radial compression to the pressure ring 2, forcing the two pressure rings 2 to be tightly pressed in the axial direction. This causes the internal sealing ring 4 to undergo elastic deformation to achieve a completely sealed state, thus realizing a fast, stable and highly airtight connection between the two pipes 1. When disassembly and maintenance are required, simply rotate the threaded rod 12 in the opposite direction to loosen the clamp and quickly separate the pipes 1.
