Description

Technical Field

[0001] This utility model relates to a lightweight transfer valve for producing aluminum profiles for new energy vehicles, belonging to the field of new energy vehicle component technology. Background Technology

[0002] In the gas delivery and control systems of new energy vehicles, multiple gas pipes typically require interconnection, diversion, or reversal to meet the gas circuit layout requirements of braking systems, air suspension systems, and thermal management systems. Due to limited vehicle space and high requirements for gas circuit safety, the connecting components between gas pipes usually employ adapter valves or connectors to achieve reliable connections and seals between gas pipes in different directions. These valves operate in high-pressure gas or gas-liquid mixed transport environments and must simultaneously possess high sealing performance, pressure resistance, and lightweight characteristics.

[0003] Existing gas transfer valves are mostly made of copper or stainless steel, and the pipeline connection is achieved through welding or threaded connections. While this structure can meet the basic gas conduction function, the overall weight of the valve body is relatively large, which is not conducive to the lightweight requirements of new energy vehicles. At the same time, the sealing in the traditional structure mostly relies on the mating of external threads and gaskets, which makes the assembly process cumbersome and the disassembly and assembly inefficient. In addition, some valve bodies have internal channels designed with right-angle intersections or acute-angle connections, which can easily generate flow losses and turbulence when airflow passes through, reducing the efficiency of the gas path.

[0004] The existing technologies have the following problems: the valve body structure is complex and heavy, which does not conform to the lightweight design trend of new energy vehicles; the connection parts mostly use threaded or welded methods, which are inconvenient for assembly and maintenance; there are problems of high flow resistance and high pressure loss at the corners of the internal flow channels, which affect the airflow efficiency of the system; the sealing performance depends on manual tightening, which is prone to leakage or loosening after long-term use, resulting in insufficient reliability.

[0005] To address the aforementioned issues, a lightweight transfer valve for producing aluminum profiles for new energy vehicles is proposed, which solves the problems of complex structure, inconvenient maintenance, unreasonable design, and poor sealing of transfer valves. Utility Model Content

[0026] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1

[0028] like Figures 1-3 As shown, a lightweight adapter valve for producing aluminum profiles for new energy vehicles includes a valve body that can be connected to an air pipe.

[0029] In this embodiment, the valve body adopts an integrated design, with a near-square block shape. The four corners of the outer surface are rounded (4), and one side of the top surface has an outwardly extending boss (5). The valve body has a through-hole (1) in the horizontal direction and a top hole (2) communicating with the front hole in the vertical direction. The front hole (1) and the top hole (2) are internally interconnected to form an L-shaped channel, used to transfer or change the direction of gas from one direction to another. The valve body is made of aluminum alloy, and after pressing and forming, the cavities, sealing grooves, etc., are precision machined.

[0030] Reference Figure 1 The front hole 1 is a cylindrical through hole that runs through one side of the valve body, with its axis in the horizontal direction and its opening on the side of the valve body. The diameter of the front hole 1 is matched with the outer diameter of the air pipe commonly used in new energy vehicles.

[0031] A stepped structure 11 is provided inside the front hole 1, as shown in the reference. Figure 1 The front hole 1 has one or more radial stepped structures 11 arranged along its axial direction. The stepped structure 11 is an annular shoulder that can form the stop surface of the pipe end. The sealing surface of the stepped structure 11 is flat.

[0032] An annular sealing groove is provided at the outlet of the front hole 1. The annular sealing groove can be used to install O-rings or other elastic seals. The seal contacts the outer wall of the connected air pipe to prevent gas leakage.

[0033] In this embodiment, a locking groove 3 is provided on the outer side of the annular sealing groove. The locking groove is a semi-annular groove with an opening along the outer side of the orifice. The locking groove 3 can cooperate with a snap ring, a buckle, or a soft locking component to fix the inserted air tube and restrict its axial movement. Limiting protrusions or inner chamfers may be provided on the groove wall to increase the locking force.

[0034] In this embodiment, the inner wall of the front hole 1 is provided with a rounded transition, which can eliminate stress concentration. The front hole 1 can be treated with a corrosion-resistant coating to extend its service life.

[0035] A top hole 2 is provided at the top of the valve body. The top hole 2 is a cylindrical protruding hole located on the top surface of the valve body, with its axis perpendicular to the axis of the front hole. An edge cylindrical boss 21 is provided on the outer side of the top hole 2. The radial dimension of the top hole 2 matches the external connector. In this embodiment, the external connector of the top hole 2 is another air pipe.

[0036] The outer side of the top hole 2 is provided with an edge cylindrical boss 21. The edge cylindrical boss 21 can serve as an external mating surface and has a certain height, which facilitates the insertion of external connectors or hoses and their mating with the valve body.

[0037] A positioning stop 22 is provided on the outer wall surface of the cylindrical boss 21. The positioning stop 22 can be a radial flange or a stepped surface. The connection between the external connector and the top hole 2 is provided with a corresponding mating groove or lip, which achieves positioning and primary sealing through the stop. A sealing groove can also be provided inside the top hole to mate with an O-ring.

[0038] A locking groove 3 is provided on the outer edge of the positioning stop 22 of the top hole 2. The locking groove 3 can be used to fix vertically inserted air tubes or other connectors.

[0039] In this embodiment, the front hole 1 and the top hole 2 are connected inside the valve body through a converging chamber, forming an L-shaped channel. A smooth transition or a chamfered edge is used at the converging point to reduce flow resistance and eddy current generation. In this embodiment, the structure at the converging point between the front hole 1 and the top hole 2 is a chamfered edge.

[0040] Within the channel connecting the front hole 1 and the top hole 2, each mating surface is provided with a sealing groove and fitted with an O-ring or sealing gasket. During actual assembly, the inserted air tube end face abuts against the stepped structure 11, and a static seal is achieved by the O-ring; the locking groove 3 provides mechanical limiting.

[0041] The locking groove 3 includes an inner groove, an outer flange, or a recess. In this embodiment, the locking groove 3 is an inner groove. The mating component can be a metal snap ring, an elastic ring, a plastic fastener, or a toothed sleeve.

[0042] The fixing process in this embodiment is as follows: one end of the air tube is inserted into the front hole or top hole to the stepped structure 11, so that the sealing ring is compressed into the sealing groove to achieve a seal. At the same time, the snap ring of the locking groove engages with the outer wall of the air tube, thereby locking the air tube and preventing it from being pulled out.

[0043] Limiting protrusions or bevels can be provided in the locking groove 3 to improve the anti-vibration tripping performance.

[0044] Reference Figure 1The valve body has an outwardly extending boss 5 on its top, with the extension points of the boss 5 forming both sides of the front hole 1. The boss 5 extending from the top surface of the valve body serves as an external mounting or positioning structure. The boss 5 can function as a positioning surface for contact with other components or as a mating surface, thereby facilitating overall assembly and weight distribution. Threaded posts, slots, or alignment holes can be provided on the boss 5 to secure the valve body to the vehicle structure.

[0045] The valve body is preferably made of aluminum alloy, which meets the requirements of lightweight and pressure resistance. The valve body is manufactured using a pressing process. The pressed valve body is then further machined using CNC precision machining. The front hole 1, top hole 2, sealing groove, and stepped structure 11 are all manufactured during machining.

[0046] In this embodiment, the assembly process is as follows:

[0047] Place the O-ring onto the step structure 11, insert the air tube until it touches the step, and the locking groove (3) engages with the snap ring to achieve fixation; if it is a top hole 2 connection, put on the external connector and let its lip engage with the positioning stop 22 to achieve positioning and sealing.

[0048] During use, gas enters along the front hole 1, then flows out through the L-shaped channel from the top hole 2 or flows in the opposite direction, completing the gas path transition. The boss 5 on the valve body can withstand vehicle operating vibrations and pressure pulsations.

[0049] During maintenance, the sealing rings on the surface of the front hole 1 and the top hole 2 are easily replaceable parts. Simply remove the retaining ring and replace the O-ring according to the maintenance cycle.

[0050] In this embodiment, the valve body is made by integral aluminum alloy pressing, which can reduce the overall weight and is beneficial for the optimization of weight-sensitive systems in new energy vehicles.

[0051] The valve body is equipped with a stepped structure 11 that works with an annular sealing groove and an O-ring to achieve static sealing. The locking groove 3 and the positioning stop 22 provide mechanical positioning, providing double leak prevention.

[0052] The slot 3 and boss positioning 22 are designed to support quick push-in or snap-fit ​​assembly, enabling rapid assembly during use.

[0053] The locating groove 3 is provided to cooperate with the retaining spring to ensure that the air tube is not easily dislodged under vibration.

[0054] The smooth transition design of the L-shaped channel between the front hole 1 and the top hole 2 reduces pressure loss and adapts to the air path turning requirements in a limited space.

[0055] The valve body is formed by pressing and then precision-machined by CNC, making it suitable for mass production and reducing the cost per valve body.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
