Description

Technical Field

[0001] The present invention relates to the field of connector technology, and more specifically, to a multi-specification adaptable quick connector device for cooling water of new energy vehicles. Background Art

[0002] The cooling water joint device of new energy vehicles is a key component that connects various components of the cooling system such as batteries, motors, electronic controls, and radiators.

[0003] Among existing published documents, patent publication number CN219282705U discloses a five-way joint device for cooling water pipes and vehicle bodies. This technology protects the cooling water pipes by addressing wear and tear caused by the vehicle's movement and interference with the vehicle's body. It also addresses the issue of unusual noise caused by vibration between the cooling water pipes and the vehicle body. It also addresses the need to merge and separate multiple cooling water pipes, as well as the need for unidirectional flow in some cooling water pipes. However, this patent has the following drawbacks.

[0004] When connecting multi-specification pipes for new energy vehicle cooling water, since the fixed joints of multiple specifications and models are in the same position, and the other matching joint pipes also have many specifications and models, the installers need to try to install the fixed joints of multiple matching joint pipes one by one. It is very easy to cause damage due to mis-insertion and installation, and it will also cause each mis-insertion to need to be disassembled and re-operated, which wastes more installation time and makes it difficult to achieve high-precision, efficient and error-free installation of multi-specification joints. For this reason, a new energy vehicle cooling water quick connector device that is compatible with multiple specifications is needed. Summary of the Invention

[0026] Technical effects and advantages of the present invention:

[0027] 1. The present invention uses a check and blocking component, and the auxiliary barcode sensor independently identifies the small check code, the medium check code, and the large check code to accurately determine the pipe specifications. The main barcode sensor is driven by a motor to rotate the shaft 120 degrees in the first stage and another 120 degrees in the second stage. The main barcode sensor sequentially identifies and locates the barcode data of the small barcode, the medium barcode, and the large barcode to achieve precise specification matching. The auxiliary barcode sensor and the main barcode sensor data are synchronously verified. Only when the two are completely consistent can the small pipe be inserted into the small joint for threaded engagement and locking, the medium pipe can only be inserted into the middle joint for threaded engagement and locking, and the large pipe can only be inserted into the large joint for threaded engagement and locking. The independent division of labor between the auxiliary barcode sensor and the main barcode sensor, the precise positioning of mechanical switching, and the double data verification triple guarantee eliminate the risk of misinsertion of pipes of different specifications, avoid wasting plug-in installation time, and achieve high-precision, efficient and error-free installation of joints of multiple specifications.

[0028] 2. The present invention utilizes a check and blocking assembly. When the match is qualified, the controller turns off the electromagnet, and the blocking strip rotates and moves downward along the positioning axis under the action of gravity. The linkage ring ensures stable movement, thereby opening the openings of the corresponding small joints, medium joints, and large joints. In this way, small pipes, medium pipes, and large pipes can only be inserted into the matching small joints, medium joints, and large joints for internal thread locking, effectively preventing misinsertion. By accurately identifying and controlling each electromagnet in stages, it is ensured that different types of pipes can only be accurately docked with corresponding joints, avoiding model confusion and achieving high-precision, efficient and error-free installation of joints of multiple specifications.

[0029] In summary, through the interaction of the above multiple functions, first, the secondary barcode sensor independently identifies the small check code, the medium check code and the large check code, and the main barcode sensor identifies and locates the barcode data of the small barcode, the medium barcode and the large barcode in turn. The secondary barcode sensor and the main barcode sensor data are synchronously verified. After the specifications are accurately matched and qualified, the openings of the corresponding small joints, medium joints and large joints are opened, so that the small pipes, medium pipes and large pipes can only be inserted into the matching small joints, medium joints and large joints for internal thread locking. In summary, the risk of mis-insertion of pipes and joints of different specifications is eliminated, damage to pipes and joints caused by mis-insertion is avoided, and the time for plug-in installation is avoided, thereby achieving high-precision, efficient and error-free installation of joints of multiple specifications.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] like Figure 1 - Figure 8 A multi-specification adaptable new energy vehicle cooling water quick connector device is shown. The multi-specification adaptable new energy vehicle cooling water quick connector device is provided with a verification and blocking component. The setting of the verification and blocking component can eliminate the risk of misinsertion of pipes and joints of different specifications, avoid damage to pipes and joints due to misinsertion, avoid wasting plug-in and installation time, and realize high-precision, efficient and error-free installation of joints of multiple specifications. The specific structural setting of the verification and blocking component is as follows.

[0041] In this embodiment, if Figure 1 - Figure 4As shown, a small joint 2, a middle joint 3 and a large joint 4 are installed at one end of the joint tube 1, and a check and blocking assembly is provided below the small joint 2. The check and blocking assembly includes: a motor 5, located below the small joint 2, the motor 5 is fixedly connected to the joint tube 1, the output end of the motor 5 is fixedly connected to the rotating shaft 6, and a secondary barcode sensor 7 is fixedly installed at one end of the rotating shaft 6; a main barcode sensor 8, fixedly connected to the outer wall of the rotating shaft 6, and the secondary barcode sensor 7 and the main barcode sensor 8 are both electrically connected to the controller 24; a small barcode 9, fixedly connected to the bottom end of the outer wall of the small joint 2, a large barcode 11 is provided below the small barcode 9, and the large barcode 11 is fixedly connected to the large joint 4; a middle barcode 10, located on one side of the large barcode 11, and the middle barcode 10 is fixedly connected to the middle joint 3. The small joint 2, the middle joint 3 and the large joint 4 are arranged in a circumferential distribution, and the small joint 2, the middle joint 3 and the large joint 4 are all fixedly connected to the joint pipe 1; the inner wall diameter of the small joint 2 is smaller than the inner wall diameter of the middle joint 3, and the inner wall diameter of the middle joint 3 is smaller than the inner wall diameter of the large joint 4. The motor 5 is electrically connected to the controller 24, and the motor 5 is used to drive the rotating shaft 6 to rotate. So that the secondary barcode sensor 7 can sense and identify the small verification code 21 as barcode data of a small model specification, and the main barcode sensor 8 can identify the barcode data of the small barcode 9 at the bottom of the small joint 2, until the barcode data identified by the main barcode sensor 8 is the same as the barcode data identified by the secondary barcode sensor 7, and the small pipe 18 can only be inserted into the interior of the small joint 2 for threaded engagement and locking. The output end of motor 5 drives shaft 6 to rotate, which drives main barcode sensor 8 to rotate counterclockwise 120 degrees until main barcode sensor 8 senses and recognizes barcode data of medium size specification for middle barcode 10, and secondary barcode sensor 7 senses and recognizes barcode data of medium size specification for middle check code 22. When the barcode data recognized by main barcode sensor 8 and secondary barcode sensor 7 are the same, middle pipe 19 can only be inserted into middle joint 3 for threaded engagement and locking. Motor 5 drives shaft 6 to continue to rotate counterclockwise 120 degrees. Main barcode sensor 8 senses and recognizes barcode data of large size specification for large barcode 11, and secondary barcode sensor 7 senses and recognizes barcode data of large size specification for large check code 23. When the barcode data recognized by main barcode sensor 8 and secondary barcode sensor 7 are the same, large pipe 20 can only be inserted into large joint 4 for threaded engagement and locking.

[0042] In this embodiment, if Figure 2 - Figure 6As shown, the outer walls of the small connector 2, the middle connector 3, and the large connector 4 are all fixedly connected to a positioning shaft 13; the outer wall of each positioning shaft 13 is rotatably connected to a blocking strip 14; an electromagnet 15 is magnetically mounted on one side of the blocking strip 14, electrically connected to the controller 24, and fixedly connected to one side of the electromagnet 15. A support strip 16 is fixedly connected to the positioning shaft 13. The outer wall of the positioning shaft 13 and the inner wall of the blocking strip 14 are both smooth, and the cross-section of the blocking strip 14 is L-shaped. So that only after the match is qualified, the electromagnet 15 in the side area of ​​the small connector 2 will be immediately closed through the controller 24, the positioning shaft 13 supports the support bar 16, the support bar 16 supports the electromagnet 15, the electromagnet 15 no longer magnetically attracts the blocking strip 14, and the blocking strip 14 rotates clockwise downward on the outer wall of the positioning shaft 13 to open the opening part of the small connector 2, ensuring that the small pipe 18 and the small connector 2 are accurately, quickly and correctly docked and installed, which can avoid errors in other pipes, reduce the damage rate of mis-insertion, and reduce the installation time of mis-insertion.

[0043] In this embodiment, if Figure 6 As shown, a linkage ring 17 is fixedly connected to the outer wall of the positioning shaft 13 and located on both sides of the blocking strip 14. The two linkage rings 17 are symmetrically arranged about the blocking strip 14. The two linkage rings 17 are rotatably connected to the blocking strip 14 so that the linkage rings 17 can limit the blocking strip 14 to rotate stably clockwise downward.

[0044] In this embodiment, if Figure 1 As shown, the other end of the joint pipe 1 is fixedly connected to a threaded sleeve 12, the inner wall of which is provided with a threaded groove. This allows the joint pipe 1 to drive the threaded sleeve 12 to rotate, and the threaded sleeve 12 is threadedly engaged and locked with the new energy vehicle cooling water main pipe, thus achieving docking installation of the new energy vehicle cooling water main pipe.

[0045] In this embodiment, if Figure 1 - Figure 8As shown, a small pipe 18 is provided on one side of the secondary barcode sensor 7, which is threadedly connected to the small connector 2. A medium pipe 19 is provided below the small pipe 18, which is threadedly connected to the medium connector 3. A large pipe 20 is provided on one side of the medium pipe 19, which is threadedly connected to the large connector 4. A small verification code 21 is bonded to the outer wall of the small pipe 18, a medium verification code 22 is bonded to the outer wall of the medium pipe 19, and a large verification code 23 is bonded to the outer wall of the large pipe 20. The inner wall diameter of the small pipe 18 is smaller than that of the medium pipe 19, which is smaller than that of the large pipe 20. This allows the small verification code 21 on the small pipe 18 to be marked with barcode data of the small model size, the medium verification code 22 on the medium pipe 19 to be marked with barcode data of the medium model size, and the large verification code 23 on the large pipe 20 to be marked with barcode data of the large model size, facilitating subsequent identification and reading.

[0046] In this embodiment, if Figure 2 As shown, the controller 24 is located on one side of the motor 5, and a battery 25 is fixedly mounted on the lower surface of the controller 24. The battery 25 powers the controller 24, and both the controller 24 and the battery 25 are fixedly connected to the joint pipe 1. This allows the battery 25 to power the controller 24, while the joint pipe 1 can provide a firm support for the battery 25 and the controller 24.

[0047] The working principle of the multi-specification compatible new energy vehicle cooling water quick connector device of the present invention is as follows:

[0048] First, when the present invention is fixedly installed, the joint pipe 1 is moved, and the joint pipe 1 drives the threaded sleeve 12 to dock with the cooling water main pipe of the new energy vehicle. By rotating the joint pipe 1, the joint pipe 1 drives the threaded sleeve 12 to rotate, and the threaded sleeve 12 is threadedly engaged and locked with the cooling water main pipe of the new energy vehicle. In this way, the joint pipe 1 supports the small joint 2 and the middle joint 3, and the joint pipe 1 can also support the large joint 4, increasing the stability of the small joint 2, the middle joint 3 and the large joint 4, and the battery 25 supplies power to the controller 24.

[0049] Secondly, when the present invention is performing a small-size specification check and blocking installation, the hand is held on the outer wall of the small pipe 18, and the small pipe 18 is moved. The small pipe 18 drives the small check code 21 to move, and the small check code 21 is laterally attached to the auxiliary barcode sensor 7. In this way, the auxiliary barcode sensor 7 senses and recognizes the small check code 21 as barcode data of small size specifications, and the joint pipe 1 supports the motor 5. The output end of the motor 5 supports the rotating shaft 6, and the rotating shaft 6 supports the auxiliary barcode sensor 7. At the same time, the rotating shaft 6 supports the main barcode sensor 8. The main barcode sensor 8 senses and recognizes the small barcode 9 at the bottom of the small joint 2 as barcode data of small size specifications. When the barcode data recognized by the main barcode sensor 8 is the same as the barcode data recognized by the auxiliary barcode sensor 7, the controller 24 will display that the match is qualified. If it is unqualified, the specification of the pipe taken is incorrect, and the pipe is replaced to continue the recognition and matching until the data is correct.

[0050] After the match is qualified, controller 24 immediately shuts off electromagnet 15 on the side of small connector 2. Meanwhile, small connector 2 supports positioning shaft 13, which in turn supports support bar 16, which in turn supports electromagnet 15. Electromagnet 15 no longer magnetically attracts blocking strip 14. Under the force of its gravity, blocking strip 14 rotates clockwise downward on the outer wall of positioning shaft 13. Simultaneously, two linkage rings 17 stabilize blocking strip 14, ensuring its stable clockwise downward rotation. This opens the opening of small connector 2, and both middle connector 3 and large connector 4 are now blocked by blocking strip 14 at their respective locations. Therefore, small pipe 18 can only be inserted into small connector 2 for threaded engagement and locking after it has been correctly verified with small connector 2. This prevents mis-insertion of small pipe 18 with middle connector 3 or large connector 4, ensuring precise, fast, and error-free docking and installation of small pipe 18 with small connector 2.

[0051] Next, when the present invention performs the medium model specification verification block installation, the controller 24 activates the motor 5. The output end of the motor 5 drives the rotating shaft 6 to rotate, which drives the main barcode sensor 8 to rotate 120 degrees counterclockwise. This rotates the main barcode sensor 8 to the position of the middle barcode 10 on the middle joint 3. Simultaneously, the rotating shaft 6 drives the secondary barcode sensor 7 to rotate 120 degrees counterclockwise until the main barcode sensor 8 senses and recognizes the middle barcode 10 as the barcode data of the medium model specification. The operator then holds the outer wall of the middle pipe 19, which drives the middle verification code 22 to move, facing the secondary barcode sensor 7 sideways. The secondary barcode sensor 7 then senses and recognizes the middle verification code 22 as the barcode data of the medium model specification. When the barcode data recognized by the main barcode sensor 8 matches the barcode data recognized by the secondary barcode sensor 7, the controller 24 displays a match. If the match fails, the specification of the pipe removed is incorrect. The pipe is then replaced and the matching process continues until the data is correct.

[0052] After the match is qualified, the controller 24 immediately turns off the electromagnet 15 on the left side of the middle connector 3. This prevents the electromagnet 15 from magnetically attracting the blocking strip 14 on the left side of the middle connector 3. Gravity causes the blocking strip 14 on the left side of the middle connector 3 to move downward along the outer wall of the positioning shaft 13. This no longer blocks the opening position on the right side of the middle connector 3. The middle pipe 19 can only be inserted into the middle connector 3 and threadedly locked after it has been correctly verified with the middle connector 3. This prevents the middle pipe 19 from being incorrectly inserted into the large connector 4 and ensures accurate, quick, and correct docking of the middle pipe 19 with the small connector 2.

[0053] Finally, when the present invention performs large-scale specification verification and blocking installation, the motor 5 is continuously started, and the motor 5 drives the rotating shaft 6 to continue rotating counterclockwise by 120 degrees. This causes the rotating shaft 6 to continue rotating counterclockwise by 120 degrees, and the main barcode sensor 8 is located in the sensing area of ​​the large barcode 11. At the same time, the rotating shaft 6 drives the secondary barcode sensor 7 to continue rotating counterclockwise by 120 degrees. This causes the main barcode sensor 8 to sense and identify the large barcode 11 as barcode data of large specifications. At the same time, the operator takes the large pipe 20, and the large pipe 20 drives the large verification code 23 to dock laterally at the position of the secondary barcode sensor 7. This causes the secondary barcode sensor 7 to sense and identify the large verification code 23 as barcode data of large specifications. When the barcode data recognized by the main barcode sensor 8 is the same as the barcode data recognized by the secondary barcode sensor 7, the controller 24 displays a qualified match. If it fails, the specification of the pipe taken is incorrect, and the pipe is replaced and the identification and matching continues until the data is correct.

[0054] After the matching is qualified, the controller 24 immediately turns off the electromagnet 15 on the left side of the large joint 4. In this way, the electromagnet 15 on the left side of the large joint 4 no longer magnetically attracts the blocking strip 14 on the left side of the large joint 4. In this way, the blocking strip 14 on the left side of the large joint 4 moves downward along the outer wall of the positioning shaft 13 under the action of gravity, and no longer blocks the opening position on the right side of the large joint 4. The large pipe 20 can only be inserted into the interior of the large joint 4 for threaded engagement and locking after it is correctly verified with the large joint 4. This prevents other pipes of the wrong model from being mistakenly inserted and installed with the large joint 4, ensuring that the medium and large pipes 20 and the large joint 4 are accurately, quickly and correctly connected and installed.
