Description

Technical Field

[0001] The utility model relates to the technical field of battery pack liquid cooling joints, in particular to a battery pack liquid cooling joint. Background Art

[0002] A battery pack refers to a battery system composed of multiple battery cells, which is usually used to store and release electrical energy. A battery pack is generally composed of battery cells, a battery management system, a battery pack casing and a connector. In order to ensure the stability of the battery pack during operation, the external cooling system is connected to the battery pack cooling component with the help of a liquid cooling joint. The liquid cooling joint is usually a key component in the thermal management system of a battery pack. Its main function is to introduce coolant into the battery pack, and through circulation, the battery temperature is effectively reduced to keep the battery within a suitable operating temperature range. Since the connection effect between the liquid cooling joint, the coolant and the battery pack directly affects the stability of the battery pack during cooling, it is necessary to stabilize the connection of the cooling liquid joint.

[0003] In the related art, during the use of the cold liquid connector, a strapping tape is generally used to connect the cold liquid connector to the external coolant pipeline and the battery pack cooling pipeline for connection and use.

[0004] However, during the current use of the cold liquid joint, after the cold liquid joint is connected to the external pipeline, the connection surface of the pipeline and the cold liquid joint is not covered with components, and external liquid and dirt can directly contact the connection of the cold liquid joint, causing the connection to be easily affected by the outside world during operation and become corroded and loose, affecting the connection stability of the cold liquid joint.

At the same time, the connection between the liquid inlet pipe 2 and the liquid outlet pipe 3 is tightened and reinforced to avoid corrosion and loosening of the connection during the working process of the liquid inlet pipe 2 and the liquid outlet pipe 3, thereby improving the connection stability of the liquid inlet pipe 2 and the liquid outlet pipe 3.

[0033] Reference Figure 1-Figure 4In a preferred embodiment, the covering mechanism includes a covering ring 4, which is movably connected to the outer sides of the liquid inlet pipe 2 and the liquid outlet pipe 3, and the inner wall of the covering ring 4 is fixedly connected with a contact ring 5, a top frame 6 is fixedly connected to the top of the covering ring 4, and a bottom frame 7 is fixedly connected to the bottom of the covering ring 4, and a force-applying frame 8 is fixedly connected to the bottoms of both sides of the top frame 6, and the tops of both sides of the bottom frame 7 are fixedly connected with force-bearing frames 9, and the force-applying connection mechanism is arranged on both sides of the top of the force-bearing frame 9. Since the force-bearing frame 9 and the force-applying frame 8 are respectively installed on both sides of the covering ring 4 through the bottom frame 7 and the top frame 6, and a contact ring 5 is installed inside the covering ring 4, when the liquid inlet pipe 2 and the liquid outlet pipe 3 are connected to the external pipeline, the covering ring 4 is first sleeved on the surface of the external pipeline. When the external pipeline is respectively connected to the liquid inlet pipe 2 and the liquid outlet pipe 3, the covering ring 4 is moved to drive the contact ring 5 to move, and the external pipeline and The connection between the liquid inlet pipe 2 and the liquid outlet pipe 3 is covered, and then the covering ring 4 is tightened by cooperating with the top frame 6 and the bottom frame 7 through the force-applying frame 8 and the force-bearing frame 9.

[0037] Specifically, the working process or working principle of the battery pack liquid cooling joint is as follows: when in use, first hold the covering ring 4 and set it on the surface of the external coolant pipeline and the battery pack connecting pipeline, and then use the strapping belt to connect the external coolant pipeline with the liquid inlet pipe 2, and connect the battery pack connecting pipeline with the liquid outlet pipe 3, and then hold the force frame 8 and the force frame 9 respectively to drive the covering ring 4 and the contact ring 5 to move through the top frame 6 and the bottom frame 7, so that the covering ring 4 drives the contact ring 5 to move to the position where the liquid inlet pipe 2 is connected to the liquid outlet pipe 3 and the external pipeline, and the liquid inlet pipe 2 is connected to the liquid outlet pipe 3 and the external pipeline. The external pipeline connection is covered and protected. At this time, the covering ring 4 and the contact ring 5 are both made of rubber material, which can contact and wrap the pipeline connection. Then, the twisting plate 15 is held and the screw 14 is rotated to cooperate with the screw hole 13 to apply a downward pulling force to the connecting strip 12, so that the connecting strip 12 drives the force frame 8 to move downward through the connecting column 11, and applies a downward force to the top frame 6. As the screw 14 rotates, the force frame 9 moves upward, so that the top frame 6 cooperates with the bottom frame 7 to apply a tightening force to the covering ring 4 and the contact ring 5, so that the covering ring 4 cooperates with the contact ring 5 to stably cover the liquid outlet pipe 3 and The connection protection and tightening reinforcement work are performed at the connection between the liquid inlet pipe 2 and the external pipeline. In this process, the connecting column 11 moves inside the connecting hole 10 to tighten the connection between the force-applying frame 8 and the force-bearing frame 9. As the screw 14 rotates, the rotating seat 17 follows the screw 14 to rotate inside the rotating groove 16, and the screw 14 and the force-bearing frame 9 are rotated to connect. At the same time, since the telescopic block 19 and the inclined groove 20 are in contact with an inclined surface, during the rotation of the rotating seat 17, the inclined groove 20 follows the rotation of the rotating seat 17 to apply a thrust to the telescopic block 19 to move outward, so that the telescopic block 19 can be rotated. The retractable block 19 is separated from the inclined slot 20, and as the retractable block 19 moves outward, the spring 21 contracts. When the retractable block 19 separated from the inclined slot 20 is aligned with the next inclined slot 20, the contracted spring 21 pushes the retractable block 19 into the inclined slot 20. When the screw 14 finishes rotating, the retractable block 19 located inside the inclined slot 20 positions the rotating seat 17 and the screw 14 to ensure the stability of the screw 14 and the rotating seat 17. When the screw 14 needs to rotate in the opposite direction, the moving handle 23 is held to drive the retractable block 19 to move outward and separate from the inclined slot 20, so that the screw 14 can be rotated in the opposite direction.
