Description

Technical Field

[0001] This application relates to the field of engine intake system technology, and in particular to a lightweight surge valve manifold assembly. Background Technology

[0002] Currently, surge valves, as key components of the engine intake system, are mainly used to mitigate the airflow impact generated by the turbocharger during operating condition switching, thus preventing surge phenomena in the intake system. The surge valve manifold assembly, serving as the connection between the surge valve and the intake pipe, directly affects the sealing performance, stability, and overall vehicle lightweighting of the intake system.

[0003] For example, a surge valve connector with application number "CN202220231919.1" includes a connecting pipe, a tightening nut, and a receiving pipe. The main body of the connecting pipe is a first pipe body, with a top connecting end and a conical ring on its side. The tightening nut is fitted onto the first pipe body, located between the top connecting end and the conical ring. The connecting pipe is connected to the receiving pipe via the tightening nut. This utility model has a simple structure, is easy to install, and has high operational stability. Through hot pressing, the fasteners are fitted onto the pipe body with protruding ends, avoiding the problem of the connector separating from the connector and easily falling off or being lost. The spiral connection design of the two mating parts of the connecting pipe ensures stable mating strength and a tight seal.

[0004] However, the existing lightweight surge valve pipe assembly has the following drawbacks: for example, after the existing pipe assembly is connected, if it needs to be adjusted according to the direction and position of the pressure relief pipe, the already installed pipe assembly needs to be disassembled and reassembled, which can easily affect the subsequent connection effect and has limitations. Utility Model Content

[0005] The purpose of this application is to address the following shortcomings of existing lightweight surge valve pipe assembly: for example, after the existing pipe assembly is connected, if it needs to be adjusted according to the different directions and positions of the pressure relief pipe, the already installed pipe assembly needs to be disassembled and reassembled, which can easily affect the subsequent connection effect and has limitations.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a lightweight surge valve connector assembly, including a connector mechanism, wherein a connecting end seat is fixedly connected to the outside of the connector mechanism, and there are two connecting end seats, which are respectively fixedly connected to the upper and lower sides of the connector mechanism. An annular groove is provided on the side of the two connecting end seats away from the connecting pipe mechanism. This annular groove is a limiting groove. A retainer is embedded inside the limiting groove. Through holes are arranged in an annular array inside the retainer. A guide ball assembly is installed inside the through holes. An extension tube is fixedly connected to the side of the two connecting end seats away from the connecting pipe mechanism. Two annular guide grooves are arranged in a linear array on the outer circumference of the extension tube. A sealing ring is sleeved on the outer side of the guide groove.

[0007] As a preferred embodiment, a through hole is provided on the outer peripheral surface of the connecting pipe mechanism, and a pressure relief pipe is embedded inside the through hole. A pressure relief flange is fixedly connected to the side of the pressure relief pipe away from the connecting pipe mechanism.

[0008] As another preferred embodiment, an upper tube is sleeved on the outer side of the upper extension cannula, and a lower tube is sleeved on the outer side of the lower extension cannula.

[0009] Further preferably, the diameters of both the upper and lower connecting tubes are larger than the extension tube, and an interface shrink tube is fixedly connected to the bottom end face of the upper connecting tube.

[0010] As a preferred embodiment, the interface tube located on the upper side matches the limiting groove located on the upper side, and an interface tube is also fixedly connected to the top surface of the lower tube.

[0011] As another preferred embodiment, the lower interface tube matches the lower limiting groove, and both the upper and lower connecting pipes have a connecting flange fixedly connected to the side away from the interface tube.

[0012] Further preferably, the main body of the connecting flange is an annular structure, and the two connecting flanges are respectively connected to the upper pipe and the lower pipe.

[0013] As a preferred embodiment, both connecting flanges and the pressure relief flange have connecting holes arranged in a ring array inside, which are used for installing bolts.

[0014] As another preferred embodiment, the interface tubes fixedly connected to the outer sides of the upper and lower tubes are in the insertion limiting groove state, and the ball guide assembly is in the rolling state of contacting the interface tubes.

[0015] In a further preferred embodiment, the ball guide assembly and the retainer together form a support structure for the interface tube shrinkage and the upper and lower tubes.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: (1) In this utility model, by designing a retainer and guide ball assembly cooperation structure in the limiting groove of the connecting end seat, when the upper and lower pipes are connected to the limiting groove by means of the interface shrink tube, they can be rotated and adjusted by relying on the rolling characteristics of the guide ball assembly. There is no need to disassemble and reassemble the already installed pipe assembly, which fundamentally solves the limitation problem of "disassembly and adjustment affecting the subsequent connection effect" in the prior art. At the same time, the rolling support of the guide ball assembly can also avoid direct friction between the interface shrink tube and the limiting groove, reduce component wear, extend the service life of the component, and further ensure the connection stability after long-term use, breaking the technical bottleneck of "adjustment must be disassembled and easily damaged after disassembly" in the existing components.

[0017] (2) In this utility model, the sealing ring around the outer periphery of the extended insertion tube ensures the sealing performance after docking, avoids air leakage affecting the efficiency of the intake system, and makes up for the defect of "seal failure after adjustment" of some existing components; the pressure relief pipe and pressure relief flange around the outer periphery of the pipe mechanism form a reliable pressure relief channel, effectively cope with the airflow impact of the turbocharger, and ensure the stability of the intake system; and the overall structural design revolves around the goal of lightweighting, such as the integrated fixing of the connecting end seat and the pipe mechanism, and the precise matching of the dimensions of each component. While meeting the requirements of sealing performance, stability and adjustability, it meets the requirements of the engine intake system for lightweight components. Compared with the existing pipe assembly that only focuses on single sealing or connection strength, it achieves a multi-dimensional technical breakthrough of "adjustable, good sealing, high stability and light weight".

[0029] like Figure 1-6The lightweight surge valve connector assembly shown includes a connector mechanism 1. Connecting end seats 2 are fixedly connected to the outer side of the connector mechanism 1. There are two connecting end seats 2, which are fixedly connected to the upper and lower sides of the connector mechanism 1 respectively. By setting connecting end seats 2 on the upper and lower sides of the connector mechanism 1, a structural foundation is provided for the upper and lower docking of the assembly. The cooperation of the limiting groove 201, the retainer 2011, and the guide ball assembly 2012 provides movable support conditions for the subsequently docked components, facilitating subsequent adjustments. The sealing ring 2015 on the outer periphery of the extension tube 2013 ensures sealing after the components are docked, preventing air leakage. The overall assembly achieves the construction of the basic connection structure, while also providing assurance for subsequent adjustments and sealing. An annular groove is provided on the side of the two connecting end seats 2 away from the connecting pipe mechanism 1. This annular groove is a limiting groove 201. A retainer 2011 is embedded inside the limiting groove 201. The retainer 2011 has through holes arranged in an annular array inside. A guide ball assembly 2012 is installed inside the through holes. An extension tube 2013 is fixedly connected to the side of the two connecting end seats 2 away from the connecting pipe mechanism 1. Two annular guide grooves 2014 are arranged in a straight array on the outer circumference of the extension tube 2013. A sealing ring 2015 is sleeved on the outside of the guide groove 2014. By embedding the pressure relief pipe 101 in the through hole on the outer circumference of the connecting pipe mechanism 1, the pressure relief channel of the component is defined, and the pressure relief function of the airflow inside the connecting pipe mechanism 1 can be realized. The setting of the pressure relief flange 1011 provides a standardized interface for the connection between the pressure relief pipe 101 and the external pressure relief related components, which facilitates subsequent stable docking and ensures reliable connection of the pressure relief channel.

[0030] The outer circumferential surface of the connecting device 1 has a through hole, into which a pressure relief connecting pipe 101 is embedded. A pressure relief flange 1011 is fixedly connected to the side of the pressure relief connecting pipe 101 away from the connecting device 1. An upper connecting pipe 3 is sleeved on the outside of the upper extension tube 2013, and a lower connecting pipe 301 is sleeved on the outside of the lower extension tube 2013. The ball guide assembly 2012 and the retainer 2011 together form a support structure for the interface tube 3011, the upper connecting pipe 3, and the lower connecting pipe 301. By sleeved on the outside of the upper extension tube 2013 and the lower connecting pipe 301, the connecting device 1 is initially connected to the upper connecting pipe 3 and the lower connecting pipe 301, thus constructing airflow extension channels on the upper and lower sides of the assembly. This allows the assembly to connect to pipes at different external locations through the upper connecting pipe 3 and the lower connecting pipe 301, expanding the connection range of the assembly.

[0031] The diameters of the upper tube 3 and the lower tube 301 are both larger than those of the extension tube 2013. An interface shrink tube 3011 is fixedly connected to the bottom end face of the upper tube 3. The interface shrink tube 3011 located on the upper side matches the limiting groove 201 located on the upper side. An interface shrink tube 3011 is also fixedly connected to the top end face of the lower tube 301. Because the diameters of the upper tube 3 and the lower tube 301 are larger than those of the extension tube 2013, it can be ensured that the extension tube 2013 can be smoothly inserted to achieve the socket connection. The interface shrink tube 3011 at the bottom of the upper tube 3 provides an adaptation structure for the precise docking of the upper tube 3 and the connecting end seat 2, avoiding docking misalignment and improving the docking accuracy of the upper tube 3.

[0032] The lower interface tube 3011 matches the lower limiting groove 201. Both the upper tube 3 and the lower tube 301 have a connecting flange 3012 fixedly connected to the side away from the interface tube 3011. The main body of the connecting flange 3012 is a ring structure, and the two connecting flanges 3012 are respectively connected to the upper tube 3 and the lower tube 301. By matching the upper interface tube 3011 with the upper limiting groove 201, the upper tube 3 and the connecting end seat 2 are accurately positioned and connected. The lower tube 301 is provided with an interface tube 3011 at the top, so that the lower tube 301 can also be adapted to the lower limiting groove 201, ensuring that the docking parts on both sides of the component can be accurately docked and ensuring the consistency of the overall docking.

[0033] The two connecting flanges 3012 and the pressure relief flange 1011 are all provided with connecting holes 3013 in a ring array inside. The connecting holes 3013 are used to install bolts. The interface shrink tube 3011 fixedly connected to the outside of the upper pipe 3 and the lower pipe 301 is in the state of being inserted into the limiting groove 201. The ball guide assembly 2012 is in the state of rolling against the interface shrink tube 3011. The matching of the lower interface shrink tube 3011 with the lower limiting groove 201 consolidates the precise docking between the lower pipe 301 and the connecting end seat 2. The connecting flange 3012 on the side of the upper pipe 3 and the lower pipe 301 away from the interface shrink tube 3011 provides a standardized flange interface for the connection of the two to external pipes or equipment, which facilitates the connection by bolts and improves the reliability of the connection.

[0034] Working principle: First, the internal movable support structure of the connecting end seat 2 is assembled: the retainer 2011 is embedded into the limiting groove 201 opened on the side of the connecting end seat 2 away from the connecting pipe mechanism 1, ensuring that the retainer 2011 fits against the inner wall of the limiting groove 201; then, the guide ball assemblies 2012 are installed one by one into the through holes opened in a ring array inside the retainer 2011, so that the guide ball assemblies 2012 can roll freely under the constraint of the retainer 2011, providing a rolling support base for the subsequent movement of the docking parts; Pre-sealing treatment of extension cannula 2013: On the outer circumferential surface of extension cannula 2013 fixedly connected in the connecting end seat 2 on the side away from the connecting tube mechanism 1, sealing rings 2015 are respectively fitted into two annular grooves opened in a straight line array. The elastic properties of sealing rings 2015 are used to make them fit tightly against the outer circumferential surface of extension cannula 2013, so as to reserve a sealing guarantee for subsequent docking of extension cannula 2013 with other connecting tubes and prevent airflow from leaking from the docking gap. The two pre-processed connecting end seats 2 are fixedly connected to the upper and lower sides of the connecting pipe mechanism 1, respectively. The fixed connection makes the connecting pipe mechanism 1 and the two connecting end seats 2 form a stable integral structure. This structure provides the core structural carrier for the vertical docking operation of the components and the subsequent realization of the pressure relief function. A through hole is opened on the outer peripheral surface of the connecting pipe mechanism 1, and the pressure relief pipe 101 is embedded in the through hole and fixed to ensure that the pressure relief pipe 101 is completely connected to the internal channel of the connecting pipe mechanism 1. Then, the pressure relief flange 1011 is fixedly connected to the side of the pressure relief pipe 101 away from the connecting pipe mechanism 1, so that the pressure relief flange 1011 and the pressure relief pipe 101 form an integrated structure. The pressure relief flange 1011 provides a standardized interface for the docking of the pressure relief pipe 101 with external pressure relief related components, ensuring the feasibility of the pressure relief function. Then, align the upper tube 3 with the extension tube 2013 located on the upper side, and sleeve the upper tube 3 on the outside of the extension tube 2013; during the sleeve process, insert the interface shrink tube 3011 fixedly connected to the bottom end face of the upper tube 3 into the limiting groove 201 of the upper connecting end seat 2. At this time, the ball guide assembly 2012 in the limiting groove 201 forms a tight contact with the outer wall of the interface shrink tube 3011, and the ball guide assembly 2012 can roll synchronously with the movement of the interface shrink tube 3011, providing flexible space for the position adjustment of the upper tube 3; Referring to the docking method of the upper tube 3, the lower tube 301 is aligned with the extension tube 2013 located on the lower side and sleeved on its outer side, so that the interface shrink tube 3011 fixedly connected to the top surface of the lower tube 301 is inserted into the limiting groove 201 of the lower connecting end seat 2, and the ball guide assembly 2012 and the interface shrink tube 3011 form an abutting rolling fit, thus completing the initial assembly of the docking parts on the upper and lower sides of the assembly. When it is necessary to adjust the upper pipe 3 and lower pipe 301 according to the direction or position of the pressure relief pipe 101, no parts need to be disassembled. Simply push the upper pipe 3 or lower pipe 301 directly. At this time, the interface shrink tube 3011 rotates around the axis of the extension tube 2013 in the limiting groove 201. The ball guide assembly 2012 rolls with the rotation of the interface shrink tube 3011 under the support of the retainer 2011, effectively reducing the friction loss between the interface shrink tube 3011 and the limiting groove 201, and ensuring a smooth adjustment process. After adjusting to the target position, the upper pipe 3 and lower pipe 301 are fixedly connected to the side of the upper pipe 3 and lower pipe 301 away from the interface shrink tube 3011 through the connecting flange 3012 fixedly connected to the side of the upper pipe 3 and lower pipe 301 away from the interface shrink tube 3011, and the mounting bolts of the connecting holes 3013 opened in a ring array inside the pressure relief flange 1011, respectively, to fix the upper pipe 3 and lower pipe 301 to the corresponding external pipes or equipment. At the same time, the pressure relief pipe 101 is fixed to the external pressure relief component, and finally the overall installation and fixing of the components are completed. When the engine intake system is running, the airflow inside the connector mechanism 1 can be delivered to the external pressure relief component through the pressure relief connector 101 to achieve effective pressure relief of the airflow, thereby alleviating the airflow impact generated by the turbocharger when switching operating conditions and avoiding surge phenomenon in the intake system. At the same time, the sealing ring 2015 on the outer periphery of the extension tube 2013 tightly fits the inner wall of the upper connector 3 and the lower connector 301 under the action of airflow pressure, completely blocking the path of airflow leakage from the docking gap and ensuring the sealing of the intake system. The support structure composed of the ball guide assembly 2012 and the retainer 2011 continuously provides stable support for the interface tube 3011, the upper connector 3 and the lower connector 301, preventing the components from shifting under the impact of airflow and ensuring the overall stability of the component operation.
