Description

Technical Field

[0001] This utility model belongs to the technical field of automotive water cooling equipment, specifically relating to a water cooling connector that prevents mis-insertion and misalignment. Background Technology

[0002] The cooling system for power batteries in new energy vehicles is one of the key technologies for ensuring battery performance and lifespan. With the rapid development of new energy vehicles, the thermal management of power batteries has become increasingly important. Water-cooled cooling systems transfer heat generated by the battery to the coolant through the coolant pipes inside the power battery, thereby reducing the battery temperature. Water-cooled connectors, as important connecting components in water-cooled cooling systems, are used to connect the coolant pipes, ensuring smooth coolant circulation. Their performance directly affects the sealing, reliability, and overall efficiency of the cooling system.

[0003] Existing water-cooling connectors lack effective anti-misinsertion designs, and their shapes may be too similar or generic. Given the numerous and complex piping systems within new energy vehicles, water-cooling connectors can be incorrectly inserted into other interfaces, affecting the normal flow of coolant and impacting the cooling process of the power battery. Furthermore, during vehicle operation, vibrations and impacts can cause water-cooling connectors to loosen or become misaligned, affecting their stability and reducing their sealing performance. Misinsertion or misalignment of water-cooling connectors can lead to poor sealing and coolant leakage. This not only reduces the efficiency of the cooling system but may also corrode electronic components within the power battery pack and even cause short circuits. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water-cooling connector that prevents mis-insertion and misalignment. The purpose is to design an effective anti-mis-insertion and anti-misalignment component for the water-cooling connector, so that the water-cooling connector can be accurately connected to the cooling pipe, preventing mis-insertion or misalignment of the water-cooling connector, and ensuring the normal flow of coolant and the cooling process of the power battery.

[0005] To achieve the above objectives, this utility model provides a water-cooled connector that prevents mis-insertion and misalignment, including a connector end, a positioning post, and a locking device; the positioning post is disposed on one side of the connector end; a cooling pipe is disposed at a position opposite to the connector end; the outer diameter of the cooling pipe is consistent with the outer diameter of the connector end; the inner wall of the cooling pipe is recessed radially inward to form a positioning groove; the size and shape of the positioning post match the size and shape of the positioning groove; a locking device is provided on the outside of the connection between the connector end and the cooling pipe.

[0006] A water-cooled connector designed to prevent mis-insertion and misalignment includes a connector end, a positioning post, and a locking device. The connector end is the part that connects the water-cooled connector to other pipelines. A cooling pipe is located opposite the connector end; this cooling pipe is a cooling channel inside the liquid cooling plate of the power battery cooling system of a new energy vehicle. The water-cooled connector is the device that connects this cooling pipe to the coolant pipeline. Because new energy vehicles have numerous and complex internal pipelines, a unique shape is required to prevent mis-insertion of the water-cooled connector to other pipeline interfaces. Therefore, a positioning post is provided on the side of the connector end near the cooling pipe. Correspondingly, the inner wall of the cooling pipe on the side near the connector end is radially recessed to form a positioning groove. The positioning post and the positioning groove cooperate to ensure accurate connection of the water-cooled connector to the cooling pipe, preventing mis-insertion. Furthermore, new energy vehicles experience vibration and impact during operation, which could lead to misalignment of the water-cooled connector. The design of the positioning groove and positioning post ensures that after the water-cooled connector is connected to the cooling pipe, the positioning groove restricts the movement of the water-cooled connector, thus preventing misalignment. In addition, a locking device is provided on the outside of the connection between the connector end and the cooling pipe, and the outer diameter of the cooling pipe is the same as the outer diameter of the connector end. The locking device can more firmly lock and fix the junction of the connected pipes to prevent it from loosening, thereby affecting the cooling process of the power battery of new energy vehicles.

[0007] Furthermore, there are three positioning posts, two of which are arranged symmetrically along the radial direction of the connector end, and the other positioning post is located between the two symmetrical positioning posts and is equidistant from the two symmetrical positioning posts; there are three positioning slots, two of which are arranged symmetrically along the radial direction of the cooling pipe, and the other positioning slot is located between the two symmetrical positioning slots and is equidistant from the two symmetrical positioning slots.

[0008] There are three positioning posts and three positioning slots. Two positioning posts or slots are symmetrically arranged in the radial direction, and the third positioning post or slot is located between the two symmetrical positioning posts or slots and is equidistant from the two symmetrical positioning posts or slots. This design ensures that the water-cooling connector can only be connected to the cooling pipe in one way, effectively achieving the function of preventing misinsertion of the water-cooling connector.

[0009] Furthermore, the end of the positioning groove away from the inner wall of the cooling pipe is semi-circular; the end of the positioning post near the outer wall of the connector end is semi-circular.

[0010] The end of the positioning groove furthest from the inner wall of the cooling pipe is semi-circular, and the end of the positioning post closest to the outer wall of the connector is also semi-circular. The matching shapes of the two ensure correct insertion of the water-cooling connector. The semi-circular design also allows the positioning post to be inserted into the positioning groove more smoothly, reducing friction during insertion.

[0011] Furthermore, the radial depth of the positioning groove is less than the outer diameter of the cooling pipe; the radial height of the positioning post is less than the outer diameter of the connector end; and the radial depth of the positioning groove is consistent with the radial height of the positioning post.

[0012] The positioning groove is recessed from the inner wall of the cooling pipe and does not penetrate the cooling pipe. The size of the positioning post should be consistent with the size of the positioning groove to ensure the correct insertion of the water-cooling connector.

[0013] Furthermore, the locking device includes a locking body, a locking extension, a locking bolt, and a locking nut; there are two locking bodies; the two locking bodies are semi-circular; the two locking bodies are symmetrically arranged on the outside of the connection between the connector end and the cooling pipe; the locking extension is located at both ends of the locking body; a through hole is provided on the locking extension; the locking bolt passes through the through hole and is connected to the locking nut.

[0014] The locking device includes a locking body, a locking extension, a locking bolt, and a locking nut. The locking body and the locking extension are integrally connected, with two locking bodies symmetrically arranged. The locking extensions are located at the ends of the locking bodies, and the two opposing locking extensions are connected by the locking bolt and the locking nut to form a locking and fixing mechanism at the connection between the connector end and the cooling pipe, preventing loosening and thus affecting the cooling process of the new energy vehicle's power battery. The locking body is semi-circular, matching the external shape of the connection between the connector end and the cooling pipe, allowing for better locking and fixing of the connection.

[0015] Furthermore, an elastic seal is provided on the outer side of the connection between the connector end and the cooling pipe; a groove is provided on the inner wall of the locking body; and the elastic seal is located in the groove.

[0016] New energy vehicles are subject to vibration and impact during operation. The installation of elastic seals can effectively prevent coolant leakage caused by vibration and impact, thus ensuring the cooling process of the power battery of new energy vehicles.

[0017] Furthermore, one end of the locking body extends outward to form an L-shaped fixing plate.

[0018] One end of the locking body extends outward with an L-shaped fixing plate. The L-shaped fixing plate is a component that connects the locking device to the cooling pipe, providing additional fixing force to the locking device and preventing the water-cooling connector from misaligning due to vibration during the operation of new energy vehicles.

[0019] Furthermore, a fixing hole is provided on the L-shaped fixing plate; a positioning pin passes through the fixing hole; the outer wall of the cooling pipe protrudes outward to form a fixing block; the fixing block of the cooling pipe is fixed to the L-shaped fixing plate by the positioning pin.

[0020] The outer wall of the cooling pipe protrudes outward to form a fixing block. The L-shaped fixing plate is fixed to the fixing block by a positioning pin, thereby fixing it to the cooling pipe and enhancing the installation stability of the water-cooled connector.

[0032] Example 1

[0033] like Figure 1 and Figure 2 The water-cooled connector shown includes a connector end 1, a positioning post 2, and a locking device 3. The positioning post 2 is located on one side of the connector end 1. A cooling pipe 4 is located opposite the connector end 1. The outer diameter of the cooling pipe 4 is the same as the outer diameter of the connector end 1. The inner wall of the cooling pipe 4 is recessed radially inward to form a positioning groove 41. The size and shape of the positioning post 2 match the size and shape of the positioning groove 41. A locking device 3 is provided on the outside of the connection between the connector end 1 and the cooling pipe 4.

[0034] A water-cooled connector designed to prevent mis-insertion and misalignment includes a connector end 1, a positioning post 2, and a locking device 3. The connector end 1 is the part that connects the water-cooled connector to other pipelines. A cooling pipe 4 is located opposite the connector end 1. This cooling pipe 4 is a cooling channel inside the liquid cooling plate of the power battery cooling system of a new energy vehicle. The water-cooled connector is the device that connects it to the coolant pipeline. Because the internal pipelines of new energy vehicles are numerous and complex, a unique shape is required to prevent mis-insertion of the water-cooled connector to other pipeline interfaces. Therefore, a positioning post 2 is provided on the side of the connector end 1 near the cooling pipe 4. Correspondingly, the inner wall of the cooling pipe 4 on the side near the connector end 1 is radially recessed to form a positioning groove 41. The positioning post 2 and the positioning groove 41 cooperate to ensure accurate connection of the water-cooled connector to the cooling pipe 4, preventing mis-insertion. Meanwhile, new energy vehicles face vibrations and impacts during operation, which may lead to misalignment of the water-cooling connector. The design of the positioning groove 41 and positioning post 2 ensures that after the water-cooling connector is connected to the cooling pipe 4, the positioning groove 41 restricts the movement of the water-cooling connector, thus preventing misalignment. In addition, a locking device 3 is provided on the outside of the connection between the connector end 1 and the cooling pipe 4, and the outer diameter of the cooling pipe 4 is consistent with the outer diameter of the connector end 1. The locking device 3 can more firmly lock and fix the junction of the connected pipes, preventing loosening and thus affecting the cooling process of the new energy vehicle's power battery.

[0035] like Figure 1 and Figure 2 As shown, there are three positioning posts 2, two of which are symmetrically arranged radially along the end 1 of the connector, and the other positioning post 2 is arranged between the two symmetrical positioning posts 2, with the distance between them being equal to that of the two symmetrical positioning posts 2; there are three positioning grooves 41, two of which are symmetrically arranged radially along the cooling pipe 4, and the other positioning groove 41 is arranged between the two symmetrical positioning grooves 41, with the distance between them being equal to that of the two symmetrical positioning grooves 41.

[0036] There are three positioning posts 2 and three positioning slots 41. Two positioning posts 2 or positioning slots 41 are symmetrically arranged in the radial direction, and the other positioning post 2 or positioning slot 41 is arranged between the two symmetrical positioning posts 2 or positioning slots 41 and the distance between the two symmetrical positioning posts 2 or positioning slots 41 is equal. This design can ensure that the water-cooling connector can only be connected to the cooling pipe 4 in one way, effectively realizing the anti-misinsertion function of the water-cooling connector.

[0037] like Figure 2 As shown, the end of the positioning groove 41 away from the inner wall of the cooling pipe 4 is semi-circular; the end of the positioning post 2 near the outer wall of the connector end 1 is semi-circular.

[0038] The end of the positioning groove 41 away from the inner wall of the cooling pipe 4 is semi-circular, and the end of the positioning post 2 near the outer wall of the connector end 1 is also semi-circular. The shapes of the two match to ensure the correct insertion of the water-cooled connector. The semi-circular design allows the positioning post 2 to be inserted into the positioning groove 41 more smoothly, reducing friction during the insertion process.

[0039] like Figure 1 and Figure 2 As shown, the radial depth of the positioning groove 41 is less than the outer diameter of the cooling pipe 4; the radial height of the positioning post 2 is less than the outer diameter of the connector end 1; the radial depth of the positioning groove 41 is consistent with the radial height of the positioning post 2.

[0040] The positioning groove 41 is recessed from the inner wall of the cooling pipe 4 and does not penetrate the cooling pipe 4. The size of the positioning post 2 should be consistent with the size of the positioning groove 41 to ensure the correct insertion of the water cooling connector.

[0042] The locking device 3 includes a locking body 31, a locking extension 32, a locking bolt 33, and a locking nut 34. The locking body 31 and the locking extension 32 are integrally connected. The two locking bodies 31 are symmetrically arranged, and the locking extension 32 is located at the end of the locking body 31. The two opposing locking extensions 32 are connected by the locking bolt 33 and the locking nut 34 to form a locking and fixing at the connection between the connector end 1 and the cooling pipe 4, preventing loosening and thus affecting the cooling process of the power battery of the new energy vehicle. The locking body 31 is semi-circular, matching the external shape of the connection between the connector end 1 and the cooling pipe 4, which can better lock and fix the connection.

[0043] like Figure 4 As shown, an elastic seal 35 is provided on the outer side of the connection between the connector end 1 and the cooling pipe 4; a groove 311 is provided on the inner wall of the locking body 31; the shape and size of the groove 311 are the same as the shape and size of the elastic seal 35; the elastic seal 35 is disposed in the groove 311.

[0044] New energy vehicles will face vibration and impact during operation. The elastic seal 35 can effectively prevent coolant leakage caused by vibration and impact, and ensure the cooling process of the power battery of new energy vehicles. The shape and size of the groove 311 are consistent with the shape and size of the elastic seal 35, so that the elastic seal 35 can be stably fixed in the groove 311, thereby forming an effective seal.

[0045] like Figure 4 and Figure 5 As shown, one end of the locking body 31 extends outward to form an L-shaped fixing plate 312, which is integrally connected with the locking body 31.

[0046] One end of the locking body 31 extends outward and is provided with an L-shaped fixing plate 312. The L-shaped fixing plate 312 is a component that connects the locking device 3 and the cooling pipe 4, and provides additional fixing force to the locking device 3, which can prevent the water cooling connector from being misaligned due to vibration during the operation of the new energy vehicle.

[0047] like Figure 1 and Figure 5 As shown, the L-shaped fixing plate 312 has a fixing hole 3121; the fixing hole 3121 is circular and passes through the two end faces of the L-shaped fixing plate 312; a positioning pin 3122 passes through the fixing hole 3121; the outer wall of the cooling pipe 4 protrudes outward to form a fixing block 42; the fixing block 42 of the cooling pipe 4 is fixed to the L-shaped fixing plate 312 by the positioning pin 3122.

[0048] The outer wall of the cooling pipe 4 protrudes outward to form a fixing block 42. The L-shaped fixing plate 312 is fixed to the fixing block 42 by the positioning pin 3122, thereby fixing it to the cooling pipe 4 and enhancing the installation stability of the water cooling connector.
