Abstract
Description
Technical Field
[0001] This application belongs to the field of automotive piping technology, and particularly relates to a nylon piping system for new energy vehicles. Background Technology
[0002] In new energy fuel cell vehicles, a hydrogen supply system is needed between the pressure reducing valve and the fuel cell stack to deliver compressed hydrogen fuel at a gauge pressure below 3000 kPa. Traditional hydrogen supply systems generally use metal hydrogen supply pipelines for delivery. As market demands for the driving range and safety of new energy fuel cell vehicles increase, the weight and cost of traditional hydrogen supply systems are also constantly increasing.
[0003] Patent CN211599782U discloses a multilayer composite nylon hydrogen supply pipeline assembly and a fuel cell electric vehicle including the assembly. The multilayer composite nylon hydrogen supply pipeline assembly includes a pressure reducing valve connection connector for connecting a pressure reducing valve, a fuel cell stack connection connector for connecting a fuel cell stack, a manual discharge valve, and two multilayer composite nylon tubes. One of the multilayer composite nylon tubes is connected at both ends to the pressure reducing valve connection connector and one end of the manual discharge valve, respectively. The other multilayer composite nylon tube is connected at both ends to the other end of the manual discharge valve and the fuel cell stack connection connector, respectively. The pressure reducing valve connection connector, the fuel cell stack connection connector, the manual discharge valve, and the two multilayer composite nylon tubes are interconnected.
[0004] The connection joints on the pipelines in the aforementioned patent rely on ordinary threads for mating and connection. Although a connection can be achieved, it is not convenient for quick installation and disassembly, and it does not take advantage of the overall layout of the pipeline system, so improvements are needed. Summary of the Invention
[0005] The purpose of this application is to provide a nylon tubing for new energy vehicles that can solve the above-mentioned problems.
[0006] The purpose of this application is to provide a nylon tubing for new energy vehicles, including:
[0007] The nylon tube body includes a first tube body, a connecting tube body, and a second tube body connected in sequence.
[0008] The connector structure includes a first connector disposed on the connecting pipe body and a second connector disposed on the first pipe body and the second pipe body;
[0009] The first connector can mate with the second connector and connect the connecting pipe body to the first pipe body and the second pipe body.
[0010] The aforementioned nylon tubing for new energy vehicles, through the design of the connector structure, enables the nylon tubing to be installed and disassembled quickly and conveniently. This improves the maintenance efficiency and flexibility of the tubing system, reduces maintenance costs and time, and the improved connector structure makes the overall layout of the tubing system more flexible and convenient. The connection method and layout of the tubing can be quickly adjusted according to actual needs to adapt to different installation environments and requirements.
[0011] Furthermore, the first connector includes a first contact head and grippers disposed on the outer wall of the first contact head:
[0012] The second connector includes a second contact head and an annular groove disposed on the second contact head, the annular groove being adapted to the gripper:
[0013] A first slot is formed between the first contact head and the gripper for the second contact head to be inserted.
[0014] The first contact head is used for contact and connection with the second connector. The grippers, made of an elastic material, are mounted on the outer wall of the first contact head and can engage with the annular groove on the second connector to achieve connection. The second contact head corresponds to the first contact head of the first connector and can be inserted into the first slot to achieve connection. The annular groove is formed on the second contact head and is adapted to the grippers of the first connector, providing a limiting function after engagement to prevent the grippers from disengaging.
[0015] The first slot is formed between the first contact head and the clamping jaws, allowing the second contact head to be inserted. During installation, simply inserting the second contact head into the first slot completes the connection. The clamping jaws, due to their elasticity, can deform to a certain extent, thus tightly fitting the second contact head and engaging with the annular groove, preventing the connector from loosening or falling off during use. The cooperation between the slot and the clamping jaws effectively improves the efficiency of connector connection and disassembly, eliminating the need for additional tools or complex operating procedures. Furthermore, the close contact of the clamping jaws ensures a good seal between the connectors.
[0016] Furthermore: the second contact head is provided with a claw, and a second slot is formed between the claw and the second contact head. The claw is inserted into the second slot and engages with the annular groove.
[0017] The jaws are mounted on the outer wall of the second contact head, forming a second slot between them. This second slot provides space for the jaws, further enhancing the stability of the connection. When the first connector is connected to the second connector, the jaws insert into the second slot and engage with the annular groove, ensuring the stability and sealing of the connector during the connection process. Both the jaws and the clamps are made of elastic material, allowing for a certain degree of deformation, which enables the first and second slots formed by them to better cooperate with the second contact head and the jaws.
[0018] The clamping jaws insert into the second slot and engage with the annular groove, while the second contact head inserts into the first slot. These two elements form a multi-layered fixing structure, ensuring the stability of the connector during connection. Simultaneously, it facilitates quick installation and disassembly. Simply insert the second contact head into the first slot and the clamping jaws into the second slot, engaging with the annular groove, to complete the connection. Disassembly is as simple as releasing the clamping jaws to remove the connector, making the operation quick and easy.
[0019] Furthermore, the outer wall of the gripper is provided with locking protrusions. There are two locking protrusions spaced apart. A disassembly groove is formed between adjacent locking protrusions for the gripper to pass through. When the gripper passes through and is disassembled, it abuts against the locking protrusion, and the first connector and the second connector are locked.
[0020] Two locking protrusions are installed on the outer wall of the gripper, spaced apart, for locking with the gripper of the second connector. A disassembly groove is formed between adjacent locking protrusions, allowing the gripper of the second connector to pass through. Once the gripper passes through the disassembly groove, it can rotate and abut against the locking protrusion, thus locking the connector. To disassemble, rotate the second connector so that the gripper aligns with the disassembly groove. At this point, the locking protrusion is no longer in contact with the gripper. Pull the first connector outwards to separate the gripper from the annular groove, completing the disassembly.
[0021] By rotating the second connector to align the jaws with the disassembly slot, the connector can be easily unlocked, making the disassembly operation simple and quick, reducing maintenance difficulty and time. Similarly, after the jaws pass through the disassembly slot, rotating the second connector can make the jaws contact the locking protrusion, improving installation efficiency.
[0022] Furthermore, the locking protrusion has a triangular cross-section, with one end facing the second contact head being an inclined surface and the other end away from the second contact head being a vertical surface perpendicular to the outer wall of the first contact head.
[0023] The locking protrusion is mounted on the outer wall of the gripper, with a triangular cross-section. The end facing the second contact head is an inclined surface, and the end away from the second contact head is a vertical surface, perpendicular to the outer wall of the first contact head. The side of the gripper that contacts the locking protrusion is flat, allowing for better contact with the vertical surface of the locking protrusion and completing the locking. In addition, the width of the disassembly groove formed between the two locking protrusions is greater than the width of the gripper.
[0024] Furthermore, the outer wall of the second contact head is provided with multiple annular grooves, and each annular groove is provided with a sealing ring, which is in close contact with the inner wall of the gripper.
[0025] The annular groove is formed on the outer wall of the second contact head. Multiple annular grooves are evenly distributed and equipped with sealing rings. The sealing rings are made of rubber or other elastic materials. When the first connector is connected to the second connector, the jaws are inserted into the second slot and engage with the annular groove. At this time, the inner wall of the jaws is in close contact with the sealing ring on the outer wall of the second contact head to form a sealing layer, which effectively prevents fluid or gas from leaking through the connector connection.
[0026] The beneficial effects of this application are:
[0027] 1. The improved joint structure enables nylon pipes to be installed and disassembled quickly and easily, thereby improving the maintenance efficiency and flexibility of the pipe system, reducing maintenance costs and time. The improved joint structure also makes the overall layout of the pipe system more flexible and convenient, allowing for quick adjustment of the pipe connection method and layout according to actual needs, adapting to different installation environments and requirements.
[0028] 2. The clamping claws are inserted into the second slot and engage with the annular slot, and the second contact head is inserted into the first slot. The two form a multiple fixing structure, which ensures the stability of the connector during the connection process, and also facilitates quick installation and disassembly.
[0029] 3. By installing multiple sealing rings on the outer wall of the second contact head, the inner wall of the gripper is in close contact with the sealing rings to form a sealing layer, which effectively prevents fluid or gas from leaking through the joint connection.

[0045] Example 2:
[0046] This application provides a nylon tubing for new energy vehicles. In addition to the above-mentioned technical features, the nylon tubing for new energy vehicles in this application also includes the following technical features.
[0047] like Figures 1 to 5 As shown, the first connector 210 includes a first contact head 211 and a gripper 212 disposed on the outer wall of the first contact head 211:
[0048] The second connector 220 includes a second contact head 221 and an annular groove 222 disposed on the second contact head 221, the annular groove 222 being adapted to the gripper 212:
[0049] A first slot 230 is formed between the first contact head 211 and the gripper 212 for the second contact head 221 to be inserted.
[0050] In this embodiment, the first contact head 211 is used to contact and connect with the second connector 220. The gripper 212, made of an elastic material, is mounted on the outer wall of the first contact head 211 and can engage with the annular groove 222 on the second connector 220 to achieve connection. The second contact head 221 corresponds to the first contact head 211 of the first connector 210 and can be inserted into the first slot 230 to achieve connection. The annular groove 222 is formed on the second contact head 221 and is adapted to the gripper 212 of the first connector 210. After engaging with the gripper 212, it provides a limiting position to prevent the gripper 212 from disengaging.
[0051] The first slot 230 is formed between the first contact head 211 and the gripper 212, and allows the second contact head 221 to be inserted. During installation, simply inserting the second contact head 221 into the first slot 230 completes the connection. The gripper 212, due to its elasticity, can deform to a certain extent, thus tightly fitting the second contact head 221 and engaging with the annular groove 222, preventing the connector from loosening or falling off during use. The cooperation between the slot and the gripper 212 effectively improves the efficiency of connector connection and disassembly, eliminating the need for other tools or complex operating procedures. Furthermore, the close contact of the gripper 212 ensures a good seal between the connectors.
[0052] Furthermore, the outer wall of the second contact head 221 is provided with a plurality of annular grooves 400, and each annular groove 400 is provided with a sealing ring 410, which is in close contact with the inner wall of the gripper 212.
[0053] An annular groove 400 is formed on the outer wall of the second contact head 221. Multiple annular grooves 400 are evenly distributed and equipped with sealing rings 410. The sealing rings 410 are made of rubber or other elastic materials. When the first connector 210 is connected to the second connector 220, the gripper 212 is inserted into the second slot 250 and engages with the annular groove 222. At this time, the inner wall of the gripper 212 is in close contact with the sealing ring 410 on the outer wall of the second contact head 221 to form a sealing layer, which effectively prevents fluid or gas from leaking through the connector connection.
[0054] Example 3:
[0055] This application provides a nylon tubing for new energy vehicles. In addition to the above-mentioned technical features, the nylon tubing for new energy vehicles in this application also includes the following technical features.
[0056] like Figures 1 to 5 As shown, the second contact head 221 is provided with a claw 240, and a second slot 250 is formed between the claw 240 and the second contact head 221. The gripper 212 is inserted into the second slot 250 and engages with the annular slot 222.
[0057] In this embodiment, the claw 240 is mounted on the outer wall of the second contact head 221, forming a second slot 250 between it and the second contact head 221. The second slot 250 provides space for the gripper 212, thereby enhancing the stability of the connection. When the first connector 210 is connected to the second connector 220, the gripper 212 is inserted into the second slot 250 and simultaneously engages with the annular groove 222, ensuring the stability and sealing of the connector during the connection process. Both the gripper 212 and the claw 240 are made of elastic material, capable of deformation to a certain extent, allowing the first slot 230 and the second slot 250 formed by them to better cooperate with the second contact head 221 and the claw 240.
[0058] The clamp 212 is inserted into the second slot 250 and engages with the annular groove 222, while the second contact head 221 is inserted into the first slot 230. These two elements form a multi-layered fixing structure, ensuring the stability of the connector during connection. Simultaneously, it facilitates quick installation and disassembly. Connection is completed simply by inserting the second contact head 221 into the first slot 230 and the clamp 212 into the second slot 250, engaging with the annular groove 222. Disassembly is achieved by simply releasing the clamp 212, making the operation simple and quick.
[0059] Example 4:
[0060] This application provides a nylon tubing for new energy vehicles. In addition to the above-mentioned technical features, the nylon tubing for new energy vehicles in this application also includes the following technical features.
[0061] like Figures 1 to 5 As shown, there are two locking protrusions 300 on the outer wall of the gripper 212. The two locking protrusions 300 are spaced apart. A disassembly groove 310 is formed between adjacent locking protrusions 300 for the gripper 240 to pass through. When the gripper 240 passes through and is disassembled, it abuts against the locking protrusion 300, and the first connector 210 and the second connector 220 are locked.
[0062] In this embodiment, two locking protrusions 300 are installed on the outer wall of the gripper 212 and are spaced apart. They are used to lock into the gripper 240 of the second connector 220. A disassembly groove 310 is formed between adjacent locking protrusions 300, through which the gripper 240 of the second connector 220 passes. After the gripper 240 passes through the disassembly groove 310, it can rotate and abut against the locking protrusion 300, thereby locking the connector. When disassembly is required, the second connector 220 is rotated so that the gripper 240 is aligned with the disassembly groove 310. At this time, the locking protrusions 300 are no longer in contact with the gripper 212. The first connector 210 is then pulled outward to separate the gripper 212 from the annular groove 222, thus completing the disassembly.
[0063] By rotating the second connector 220 to align the claw 240 with the disassembly slot 310, the connector can be easily unlocked, making the disassembly operation of the connector simple and quick, reducing maintenance difficulty and time. Similarly, after the claw 240 passes through the disassembly slot 310, rotating the second connector 220 can make the claw 240 contact the locking protrusion 300, improving installation efficiency.
[0064] Furthermore, the locking protrusion 300 has a triangular cross-section, with one end facing the second contact head 221 being an inclined surface and the other end away from the second contact head 221 being a vertical surface and perpendicular to the outer wall of the first contact head 211.
[0065] The locking protrusion 300 is mounted on the outer wall of the gripper 212. It has a triangular cross-section, with one end facing the second contact head 221 being an inclined surface and the other end away from the second contact head 221 being a vertical surface, perpendicular to the outer wall of the first contact head 211. The side of the gripper 240 that contacts the locking protrusion 300 is flat, allowing for better contact with the vertical surface of the locking protrusion 300 and thus locking. Furthermore, the width of the disassembly groove 310 formed between the two locking protrusions 300 is greater than the width of the gripper 240.
