Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically a self-sealing detachable pipeline connector. Background Technology

[0002] Thermal management technology involves placing a liquid cooling plate at the bottom of the battery and filling the plate with coolant. The heat generated during fast charging is carried away by the circulating flow of the coolant, ensuring thermal performance safety. To remove heat in a timely manner, the circulation of the coolant needs to be improved. Pipe joints are usually used to connect the pipes in the cooling circulation.

[0003] The existing utility model patent CN222811348U proposes a male connector, a female connector and a quick connector assembly. This utility model pushes the pull rod inward under the cooperation of the pin and the inner groove, which drives the first positioning ring to move in the slide groove, and makes one end of the pin connect to the inner groove to limit the nut and prevent the nut from rotating during use.

[0004] As described in the above technical solution, the first positioning ring and spring are driven by the movable pull rod to prevent the nut from rotating during use. However, the above device has the problem of the connecting nut cracking during the connection process. Since the male and female heads are directly connected by the nut, the nut is prone to cracking during long-term use, which will affect the normal connection of the pipeline. Utility Model Content

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The self-sealing, detachable pipe joint provided by this utility model has the following advantages over the prior art:

[0025] (1) Through the cooperation of the male and female connectors and the mounting bracket, the mounting bracket is fixedly connected to the external liquid cooling plate, so that the male connector is installed on the mounting bracket and the mounting bracket is installed on the external liquid cooling plate. This avoids the direct installation of the female connector through threads or nuts, and avoids the problems of nut loosening and cracking that may be caused by direct thread connection. This improves the reliability and service life of the pipe joint. At the same time, the mounting bracket installed on the external liquid cooling plate can limit the female connector and ensure the stability of the male and female connector installation.

[0026] (2) By embedding a thermoplastic nut in the mounting hole of the mounting plate, setting a first sealing ring at the insertion head of the male connector, and setting a stop wall on the first pipe body, the connection strength between the male connector and the mounting bracket is significantly improved, preventing the nut from loosening or cracking, and ensuring the sealing of the male and female connectors, so as to ensure that the coolant will not leak. The setting of bolts and thermoplastic nuts enables quick disassembly and installation of the male and female connectors. At the same time, the stop wall restricts the relative position of the vehicle pipeline connection, ensuring the reliability of the insertion.

[0027] (3) The second tube body and the support ring are designed with an interference fit between the second tube body and the male end, which further enhances the sealing performance and ensures that the coolant flows smoothly in the pipeline. At the same time, the support ring not only enhances the structural strength of the female end, but also provides stable support by contacting the external liquid cooling plate, preventing loosening or displacement during use.

[0028] (4) By providing a second annular groove at the bottom of the support ring and a second sealing ring in the second annular groove, a double seal is formed. The support ring is provided with a limiting ring at the corresponding external liquid cooling plate, which significantly improves the reliability of the entire pipeline joint system and reduces the safety risks caused by sealing problems. At the same time, the limiting ring effectively prevents the support ring from shifting or loosening during use, further enhancing the connection stability between the female head and the liquid cooling plate, ensuring the correct installation position between the female head and the liquid cooling plate, improving installation accuracy, and reducing sealing problems caused by improper installation.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-5 This application proposes a self-sealing detachable pipe connector, including a male connector 1, a female connector 2, and a mounting bracket 3.

[0037] like Figure 1-2 As shown, the mounting bracket 3 has clearance holes 31 at both ends corresponding to the male head 1 and the female head 2. The side of the mounting bracket 3 corresponding to the female head 2 can be fixed to the external liquid cooling plate connected to the female head 2. The male head 1 is inserted into the clearance hole 31 and can be fixedly connected to the mounting bracket 3. The female head 2 is sleeved on the male head 1, and the female head 2 abuts against the external liquid cooling plate and is connected to the external liquid cooling plate.

[0038] Specifically, the male connector 1 is mounted on the mounting bracket 3, which is mounted on the external liquid cooling plate. This avoids direct installation with the female connector 2 via threads or nuts, thus avoiding problems such as nut loosening and cracking that may occur with direct threaded connections. This improves the reliability and service life of the pipe joint. At the same time, the mounting bracket 3, mounted on the external liquid cooling plate, can limit the position of the female connector 2, ensuring the stability of the installation of the male connector 1 and the female connector 2.

[0039] In some embodiments, such as Figure 1-2 , Figure 4 As shown, the male connector 1 includes a first tube body 11, an insertion head 12, and a mounting plate 13. The mounting plate 13 is located at one end of the first tube body 11 corresponding to the female connector 2. The mounting plate 13 has a mounting hole 14. The mounting plate 13 is fixedly connected to the mounting bracket 3 by bolts passing through the mounting hole 14. The insertion head 12 is located on the side of the mounting plate 13 corresponding to the female connector 2. The insertion head 12 can be inserted into the female connector 2.

[0040] Specifically, the mounting plate 13 fixes the first pipe body 11 to the mounting bracket 3 with bolts, replacing the traditional method of directly connecting the male head 1 and the female head 2 with threads or nuts. This ensures the connection strength while avoiding cracking at the connection point of the male head 1 and the female head 2, thus improving the reliability and service life of the pipe joint.

[0041] In some embodiments, such as Figure 1-5 As shown, a thermoplastic nut 17 is embedded in the mounting hole 14, and a first rivet nut 32 adapted to the bolt is provided on the mounting bracket 3 at the position corresponding to the thermoplastic nut 17. The bolt and the thermoplastic nut 17 are set together to realize quick disassembly and installation of the male and female heads. A first annular groove 15 is provided on the periphery of the insertion head 12, and a first sealing ring 16 is provided in the first annular groove 15. The male head 1 also includes a stop wall 18, which is located at the end of the first tube body 11 facing away from the female head 2.

[0042] Specifically, the embedded hot melt nut 17 reduces the likelihood of cracking when the mounting plate 13 is installed on the mounting bracket 3, significantly improving the connection strength between the male connector 1 and the mounting bracket 3 and ensuring the reliability of the connection; a first sealing ring 16 is provided around the insertion head 12 to ensure its sealing when it is inserted and mated with the female connector 2; at the same time, the stop wall 18 restricts the relative position of the vehicle pipeline insertion to ensure the reliability of the insertion.

[0043] In some embodiments, such as Figure 1-2 As shown, the female connector 2 includes a second tube body 21 and a support ring 22. The second tube body 21 is sleeved on the male connector 1 and is interference-fitted with the male connector 1. The support ring 22 is located on the side of the second tube body 21 facing away from the male connector 1 and abuts against the external liquid cooling plate.

[0044] Specifically, the second pipe body 21 and the support ring 22 are designed with an interference fit between the second pipe body 21 and the male connector 1, which further enhances the sealing performance and ensures that the coolant flows smoothly in the pipeline. At the same time, the support ring 22 not only enhances the structural strength of the female connector 2, but also provides stable support by abutting against the external liquid cooling plate, preventing loosening or displacement during use.

[0045] In some embodiments, such as Figure 4-5 As shown, the inner side of the second tube 21 corresponding to the male head 1 is set in an inverted cone shape; the bottom of the support ring 22 is provided with a second annular groove 23, and a second sealing ring 24 is provided in the second annular groove 23; the support ring 22 is provided with a limiting ring 25 corresponding to the external liquid cooling plate.

[0046] Specifically, by providing a second annular groove 23 at the bottom of the support ring 22, and a second sealing ring 24 within the second annular groove 23, which works in conjunction with the first sealing ring 16 to form a double seal, and by providing a limiting ring 25 at the external liquid cooling plate corresponding to the support ring 22, the reliability of the entire pipeline joint system is significantly improved, and the safety risks caused by sealing problems are reduced. At the same time, the limiting ring 25 effectively prevents the support ring 22 from shifting or loosening during use, further enhancing the connection stability between the female connector 2 and the liquid cooling plate, ensuring the correct installation position between the female connector 2 and the liquid cooling plate, improving installation accuracy, and reducing sealing problems caused by improper installation.

[0047] In some embodiments, such as Figure 1-2 As shown, the mounting bracket 3 is provided with a second rivet nut 33 at the location corresponding to the external liquid cooling plate, which can be fixedly connected to it. The connection strength between the mounting bracket 3 and the liquid cooling plate is further enhanced by the fixing of the second rivet nut 33, ensuring the stability of the entire pipeline joint system, preventing loosening or displacement during use, and extending the service life.
