Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe joints, in particular to a new energy automobile cooling pipe joint. BACKGROUND

[0002] Under the promotion of global energy structure transformation, new energy vehicles have become the core direction of automobile industry upgrading, among which the proportion of pure electric vehicles is more than that of traditional fuel vehicles. The core power unit, power battery, drive motor, electric control system and auxiliary system, vehicle-mounted charging system and air conditioning system of pure electric vehicles and hybrid electric vehicles are extremely sensitive to temperature. Their working efficiency, service life and safety performance directly depend on precise temperature control. This demand has led to the technical iteration of new energy vehicle cooling management system. As the connecting hub of medium transportation in the cooling management system, the performance of the pipe joint directly determines the reliability and efficiency of the system.

[0003] The existing pipe joint of the traditional new energy vehicle is prone to loosening and falling off during vehicle driving due to factors such as bumping and vibration, which causes cooling medium leakage and affects the normal operation of the cooling management system. The traditional joint is mostly fixed only once, and lacks effective secondary reinforcement structure. In the long-term use process, the components are prone to fatigue deformation, which leads to reduced clamping force, and further causes joint loosening and leakage. The traditional joint relies on the compression deformation of the sealing ring at the initial installation to achieve sealing, and does not have an active compensation function. With the increase of use time, the sealing ring is prone to aging and loss of elasticity, which produces small gaps and causes cooling medium leakage, posing a safety hazard. SUMMARY

[0009] Preferably, both the first and second arc-shaped fastening clamps have placement grooves on their sides.

Two sets of electric telescopic rods are symmetrically arranged at the bottom of the inner wall of the placement groove. The movable end of the electric telescopic rod is fixedly connected to a clamping plate. The fixed bracket is fixedly connected to one side of the first pipe body. After the pipe is initially connected, the arc-shaped clamp is moved to a suitable position. Pressing the pressing plate drives the second and third rotating frames to rotate the arc-shaped clamp around the rotating axis and clamp the pipe. When the clamp is in place, the limiting rod is inserted into the limiting hole to fix the pressing plate to prevent rebound. The electric telescopic rod is started, which drives the clamping plate to extend out of the placement groove and lock into the limiting groove of the fixed base to further enhance the fastening. When disassembling, the limiting rod is pulled out, the electric telescopic rod is retracted to reset the clamping plate, and the pressing plate is operated in reverse to release the clamp.

[0010] Preferably, the sealing reinforcement mechanism includes a threaded tube, on which a handle is sleeved and fixedly connected.

[0012] This invention provides a cooling pipe connector for new energy vehicles. It has the following beneficial effects:

[0013] 1. This new energy vehicle cooling pipe joint only requires pushing the first pipe body to insert the docking ring into the docking groove during installation, and rotating the second pipe body to allow the clamping rod to automatically engage with the first annular groove. This eliminates the need for repeated bolt tightening or welding, significantly reducing the difficulty of operation for workers. At the same time, the first spring applies a continuous pushing force to the third pipe body through the fourth pipe body, ensuring that the first rotating bracket is always in close contact with the second and first annular grooves. This makes the pipe connection more secure and prevents leakage caused by loosening due to vibration. During disassembly, rotating the third pipe body in the opposite direction will allow the fixing block to pop out with the help of the spring force, eliminating the need for violent disassembly, protecting the docking ring, clamping rod, and other components, and extending the overall service life of the joint.

[0014] 2. This new energy vehicle cooling pipe joint, based on the initial connection, is further reinforced by an arc-shaped fastening clamp and an electric telescopic rod, which further improves the reliability of the connection. When the pressing plate drives the arc-shaped clamp to clamp the pipe, the limit rod inserted into the limit hole can prevent the clamp from rebounding, avoiding the decrease in clamping force due to fatigue deformation during long-term use. The electric telescopic rod drives the clamping plate to engage with the limit groove of the fixed base, forming a double guarantee of clamping and locking, avoiding the risk of joint loosening. Disassembly only requires pulling out the limit rod, retracting the electric telescopic rod, and operating the pressing plate in the opposite direction. The steps are clear and non-destructive, avoiding pipe deformation and joint damage caused by traditional violent disassembly.

[0015] 3. This new energy vehicle cooling pipe joint achieves active sealing compensation by driving a flexible extrusion plate through a threaded pipe. Turning the handle allows the flexible extrusion plate to gently squeeze the sealing ring, causing it to deform and fill the tiny gaps at the joint. This effectively solves the problem of leakage after prolonged use of traditional joints, which are well-sealed during installation. It also avoids safety hazards caused by leakage of cooling medium. At the same time, the reverse elastic force of the second spring can buffer the extrusion force of the flexible extrusion plate and prevent the sealing ring from deforming and breaking due to excessive operating force.

[0016] 4. In this new energy vehicle cooling pipe joint, the heating wire can heat the lubricating oil to a suitable flow temperature, preventing the lubricating oil from becoming viscous at low temperatures and causing delivery interruptions. The lubricating oil evenly covers the surface of the sealing ring and the contact surface of the mating parts, preventing excessive friction on the sealing ring from damaging it and causing poor sealing performance, thus extending the service life of the sealing ring and improving the sealing performance of the pipe joint.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] For the first embodiment, please refer to... Figures 1-5This invention provides a technical solution: a cooling pipe joint for new energy vehicles, comprising a first pipe body 1 and a second pipe body 2. A connecting ring 3 is fixedly connected to one end of the first pipe body 1, and a connecting groove 4 is formed at one end of the second pipe body 2. The connecting ring 3 is disposed inside the connecting groove 4 and slidably connected to the inner wall of the connecting groove 4. A sealing ring 5 is placed on one side of the inner wall of the connecting groove 4, and a first movable groove 6 is formed on one side of the inner wall of the connecting groove 4. A sealing reinforcement mechanism 17 is threaded through and threadedly connected to one side of the inner wall of the first movable groove 6. One end of the first pipe body 1 communicates with the second pipe body 2, and disassembly and assembly mechanisms are uniformly fixedly connected to the inner wall of the first pipe body 1. 7. A fixing mechanism 8 is fixedly connected to the side of the first tube 1. The fixing mechanism 8 is located between the first tube 1 and the second tube 2. A fixing base 9 is fixedly connected to the portion of the first tube 1 and the second tube 2 located on the side of the fixing mechanism 8. A limiting groove 10 is formed on the side of the fixing base 9. A first bracket 11 is fixedly connected to the portion of the first tube 1 and the second tube 2 located on the side of the fixing mechanism 8. A limiting rod 12 is slidably connected through the side of the first bracket 11. A lubrication mechanism 13 is fixedly connected to the side of the first tube 1. A first annular groove 14 is formed on the inner wall of the second tube 2. A fixing rod 15 is fixedly connected to the inner wall of the first tube 1. A third tube 16 is fixedly connected to the end of the fixing rod 15 away from the second tube 2. A sliding groove 18 is formed on the inner wall of the first tube 1. A sliding block 19 is slidably connected to the inner wall of the sliding groove 18. A fourth tube 20 is fixedly connected to the side of the sliding block 19 away from the sliding groove 18. A first spring 21 is fixedly connected to one end of the fourth tube 20. A fifth tube 22 is fixedly connected to the end of the first spring 21 away from the fourth tube 20. The side of the fifth tube 22 is fixedly connected to the inner wall of the first tube 1. A second annular groove 161 is formed on the third tube 1. The portion of the 6 located on one side of the second annular groove 161 is provided with a second movable groove 162, which is connected to the second annular groove 161. The disassembly and assembly mechanism 7 includes a second bracket 71, and a first rotating frame 72 is rotatably connected to the inner wall of the second bracket 71. A fixing block 73 is fixedly connected to one end of the first rotating frame 72, and a locking rod 74 is fixedly connected to the end of the first rotating frame 72 away from the fixing block 73. The second bracket 71 is provided with multiple sets and is evenly fixedly connected to the inner wall of the first tube 1. The fixing block 73 extends into the interior of the second annular groove 161, and the locking rod 74 extends into the interior of the first annular groove 14.

[0029] In use, align the mating ring 3 at one end of the first tube 1 with the mating groove 4 at one end of the second tube 2, and slowly push the first tube 1 so that the mating ring 3 slides on the inner wall of the mating groove 4 until the mating ring 3 is fully inserted into the mating groove 4. At this time, the sealing ring 5 is squeezed between the mating ring 3 and the mating groove 4, which plays a preliminary sealing role. At the same time as mating, the third tube 16 squeezes the first rotating frame 72, causing the first rotating frame 72 to rotate and retract. Then rotate the second tube 2 to drive the third tube 16 to rotate until the second movable groove 162 on the third tube 16 aligns with the fixed block 73. During the process, the opening is slow. As the docking progresses, the fixing block 73 continues to move along the second movable groove 162 until it moves into the second annular groove 161. Since the depth of the second annular groove 161 is deeper than that of the second movable groove 162, the angle of the first rotating frame 72's rotation and opening increases. At this time, the locking rod 74 also rotates with the opening of the first rotating frame 72 to the position of the first annular groove 14 and locks into the first annular groove 14, completing the connection and fixing of the first tube body 1 and the second tube body 2 (corresponding to the disassembly and assembly mechanism 7). During installation, due to the movement of the third tube body 16, the fourth tube... Body 20 is compressed by the third tube 16, so the fourth tube 20 slides along the sliding groove 18 toward the fifth tube 22, while compressing the first spring 21. After the first tube 1 and the second tube 2 are connected and fixed, under the elastic force of the first spring 21, the fourth tube 20 tends to slide away from the fifth tube 22, thus generating a continuous thrust on the third tube 16. This ensures that the first rotating frame 72 always maintains close contact with the second annular groove 161 and the first annular groove 14, making the installation more secure. Furthermore, when disassembly is required... During disassembly, simply rotate the third pipe body 16 in the opposite direction to rotate the fixing block 73 to one side of the second movable groove 162. At this time, the elastic force of the first spring 21 pushes the fourth pipe body 20 to reset. The fourth pipe body 20 drives the third pipe body 16 to generate a reverse thrust, causing the fixing block 73 to pop out along the second movable groove 162. This causes the first rotating frame 72 to rotate and retract, and the locking rod 74 to slide out from the first annular groove 14, thereby easily separating the first pipe body 1 from the second pipe body 2 and completing the disassembly operation. In summary, the pipe can be installed conveniently and securely without complicated steps.

[0030] Second embodiment, please refer to Figures 1-7Based on the first embodiment, the present invention provides a technical solution: the fixing mechanism 8 includes a fixing bracket 81, with a first rotating shaft 82 and a second rotating shaft 83 respectively passing through and rotatably connected to both sides of the fixing bracket 81. A first arc-shaped fastening clamp 84 and a second arc-shaped fastening clamp 85 are respectively fixedly connected to the sides of the first rotating shaft 82 and the second rotating shaft 83. A connecting base 86 is fixedly connected to the end of the first arc-shaped fastening clamp 84 away from the first rotating shaft 82. Rotating rods 811 are fixedly connected to both sides of the connecting base 86. A third rotating shaft 87 is passed through and rotatably connected to the end of the second arc-shaped fastening clamp 85 away from the second rotating shaft 83. A second rotating frame 88 is sleeved and rotatably connected to both ends of the third rotating shaft 87. A second rotating frame 88 is passed through and rotatably connected to the end of the second rotating frame 88 away from the third rotating shaft 87. A fourth rotating shaft 89 is provided, and a third rotating frame 810 is fitted and rotatably connected to both ends of the fourth rotating shaft 89. The end of the third rotating frame 810 away from the fourth rotating shaft 89 passes through and is rotatably connected to the rotating rod 811. A pressing plate 812 is fixedly connected to the side of the second rotating frame 88. A connecting bracket 813 is fixedly connected to the top of the pressing plate 812. A limit hole 814 is opened on the side of the connecting bracket 813. Placement grooves 815 are opened on the sides of the first arc-shaped fastening clamp 84 and the second arc-shaped fastening clamp 85. The fixed end of the electric telescopic rod 816 is fixedly connected to the bottom of the inner wall of the placement groove 815. Two sets of electric telescopic rods 816 are provided and symmetrically arranged at the bottom of the inner wall of the placement groove 815. A clamping plate 817 is fixedly connected to the movable end of the electric telescopic rod 816. A fixed bracket 81 is fixedly connected to one side of the first tube body 1.

[0031] In use, after the first tube 1 and the second tube 2 are initially connected and installed, the first arc-shaped fastening clamp 84 and the second arc-shaped fastening clamp 85 are moved to a suitable position (corresponding to the fixing mechanism 8) by pressing the pressing plate 812. Then, the pressing plate 812 is pressed, which drives the second rotating frame 88 to rotate around the third rotating shaft 87. The second rotating frame 88 drives the third rotating frame 810 to rotate through the fourth rotating shaft 89. The third rotating frame 810 then rotates around the rotating rod 811, thereby causing the first arc-shaped fastening clamp 84 and the second arc-shaped fastening clamp 85 to rotate around the first rotating shaft 82 and the second rotating shaft 83, gradually approaching and clamping the first tube 1 and the second tube 2. When clamping to a certain extent, the position of the limiting hole 814 corresponds to the position of the limiting rod 12. The limiting rod 12 is then inserted into the limiting hole 814. In step 14, the pressing plate 812 is limited to prevent it from rebounding, ensuring the clamping effect of the first arc-shaped fastening clamp 84 and the second arc-shaped fastening clamp 85 on the first tube 1 and the second tube 2. At this time, the electric telescopic rod 816 is activated. The movable end of the electric telescopic rod 816 drives the clamping plate 817 to extend out of the placement groove 815. The clamping plate 817 is inserted into the limiting groove 10 of the fixed base 9 on the first tube 1 and the second tube 2 to further enhance the stability of the fixation. When disassembly is required, the limiting rod 12 is first pulled out from the limiting hole 814, and then the electric telescopic rod 816 is controlled to retract, so that the clamping plate 817 retracts into the placement groove 815. Then the pressing plate 812 is operated in reverse to loosen the first arc-shaped fastening clamp 84 and the second arc-shaped fastening clamp 85 from the first tube 1 and the second tube 2, thus completing the disassembly operation.

[0032] Third embodiment, please refer to Figures 1-8 Based on the second embodiment, the present invention provides a technical solution: the sealing reinforcement mechanism 17 includes a threaded tube 171, a handle 172 is sleeved and fixedly connected to the threaded tube 171, a flexible extrusion plate 173 is fixedly connected to one end of the threaded tube 171, a through hole 174 is opened at the bottom of the flexible extrusion plate 173, the through hole 174 communicates with the threaded tube 171, and a second spring 175 is fixedly connected to the top of the flexible extrusion plate 173 on both sides of the threaded tube 171. The threaded tube 171 passes through the side of the second tube body 2 and extends into the interior of the first movable groove 6. The end of the second spring 175 away from the flexible extrusion plate 173 is fixedly connected to the inner wall of the first movable groove 6.

[0033] During use, to avoid poor sealing caused by tiny gaps and irregular surfaces at pipe joints, when the gaps become larger and the sealing deteriorates, turn the handle 172. Turning the handle 172 rotates the threaded tube 171. Since the threaded tube 171 is threaded to the side of the second pipe body 2, it moves along its axis into the first movable groove 6 during rotation, thereby moving the flexible extrusion plate 173 into the first movable groove 6. During this movement, the bottom of the flexible extrusion plate 173 contacts the mating surface, tightly adhering to the surface of the sealing ring 5. With continued movement, the flexible extrusion plate 173 gently and continuously compresses the sealing ring 5, causing it to deform and better fill the tiny gaps and irregular surfaces at the pipe joint, thus enhancing the sealing effect. Simultaneously, the second spring 175 is compressed, generating a reverse elastic force on the flexible extrusion plate 173, allowing it to more stably and gently compress the sealing ring 5, preventing excessive pressure that could damage it.

[0034] For the fourth embodiment, please refer to [link / reference]. Figures 1-9 Based on the third embodiment, the present invention provides a technical solution: the lubrication mechanism 13 includes a miniature oil reservoir 131, an electric heating wire 132 is fixedly connected to the inner wall of the miniature oil reservoir 131, the oil inlet of the miniature pump 133 is connected to the side of the miniature oil reservoir 131, the oil outlet of the miniature pump 133 is connected to the connecting oil pipe 134, the end of the connecting oil pipe 134 away from the miniature pump 133 is connected to the threaded pipe 171, and the miniature oil reservoir 131 is fixedly connected to the side of the second pipe body 2.

[0035] In use, the micro pump 133 of the lubrication mechanism 13 is activated, and the micro pump 133 draws lubricating oil from the micro oil tank 131. The lubricating oil passes through the heating area of ​​the heating wire 132. In cold environments, heating can prevent the lubricating oil from becoming viscous due to low temperature, which would affect its flow. After being heated to a suitable temperature, it is delivered to the threaded tube 171 through the connecting oil pipe 134. Since the threaded tube 171 is connected to the flexible extrusion plate 173, and the bottom of the flexible extrusion plate 173 has a through hole 174, the lubricating oil is evenly coated on the surface of the sealing ring 5 through the through hole 174 and flows along the mating groove 4 through the entire body of the sealing ring 5. This can reduce friction between components in daily use, extend service life, and provide lubrication for the contact surface between the flexible extrusion plate 173 and the sealing ring 5 when the sealing reinforcement mechanism 17 is working, ensuring smooth extrusion and further improving the reliability and durability of the overall device.

[0036] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
