Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and more specifically, to a connector device and an energy storage system. Background Art

[0002] In an energy storage system, there are compartments such as a battery compartment, an electrical compartment, and a liquid cooling compartment, and different compartments are separated by walls. When the liquid cooling assembly of the energy storage system cools the batteries in the battery compartment or the electrical components in the electrical compartment, the liquid cooling pipe needs to pass through the wall. Because the sealing protection levels of different compartments are different, after the liquid cooling pipe passes through the wall, the gap between the liquid cooling pipe and the wall needs to be sealed. However, the structure of the liquid cooling pipe and the wall in the related art to achieve sealed installation is complex, resulting in low efficiency of liquid cooling pipe installation. Utility Model Content

[0003] The embodiments of the present utility model provide a connector device and an energy storage system.

[0004] The connector device of the embodiment of the present application includes a first connector and a connector assembly, the first connector is used to pass through the wall of the energy storage system, the connector assembly includes a first seal, a second connector, a clamping member and a sleeve, the first seal is sleeved on the first connector and used to abut against the wall, the second connector is docked with the first connector and connected to the sleeve, the clamping member is clamped with the first connector, the sleeve is sleeved on the first connector and one end presses against the first seal, the clamping member abuts against the sleeve to limit the movement of the sleeve relative to the first connector, thereby limiting the movement of the connector assembly relative to the first connector.

[0005] In the joint device of the above embodiment, the sleeve and the clamping member cooperate to limit the position of the first sealing member. The first sealing member is sleeved on the first joint, so that the gap between the first joint and the wall can be sealed in the radial direction of the first joint. In addition, the first sealing member is used to abut against the wall, thereby sealing the gap between the first joint and the wall in the axial direction of the first joint, and the structure is simple; further, the joint assembly is clamped to the first joint through the clamping member to limit the movement of the joint assembly relative to the first joint, so that the assembly of the first joint and the joint assembly is convenient, which is beneficial to improving the efficiency of installing the joint device on the wall.

[0006] In certain embodiments, the retaining member includes a ring body and a protrusion radially extending from the ring body. The ring body is engaged with the first connector, and the protrusion abuts against a side of the sleeve axially away from the first seal. Thus, the retaining member can be engaged with the first connector via the ring body, and the protrusion abuts against one axial side of the sleeve, thereby maintaining a stable position of the sleeve relative to the first connector, thereby securing the entire connector assembly relative to the first connector.

[0007] In certain embodiments, the sleeve has a notch extending through its sidewall. The protrusion extends through the notch and abuts against its bottom surface, which faces the axial direction of the sleeve. The second connector is located on the side of the ring body away from the first seal. This notch reduces interference between the second connector and the retaining member, and allows the retaining member to engage the first connector closer to the wall, thereby shortening the axial length of the first connector.

[0008] In certain embodiments, the second connector is engaged with the socket and presses against the retaining member along the axial direction of the first connector. Thus, the second connector and the socket are connected by a snap connection, making them easy to disassemble. Furthermore, the second connector presses against the retaining member along the axial direction of the second connector, thereby limiting the axial position of the retaining member and ensuring a secure connection between the first connector and the connector assembly.

[0009] In some embodiments, one of the second connector and the socket is provided with a first protrusion, and the other is provided with a first slot, wherein the first protrusion is locked in the first slot. Thus, the first protrusion and the first slot are cooperatively connected, making it easy for the second connector and the socket to be locked together.

[0010] In some embodiments, a groove is provided on a side of the first sealing member facing away from the wall, and one end of the sleeve is inserted into the groove. Thus, when one end of the sleeve is inserted into the groove, the sleeve can more stably press against the first sealing member, thereby improving the sealing effect of the first sealing member.

[0011] In some embodiments, a second sealing member is provided between the first joint and the second joint, and the second sealing member seals the gap between the first joint and the second joint. In this way, the second sealing member can improve the sealing effect between the first joint and the second joint.

[0012] In some embodiments, one of the first connector and the clamping member is provided with a second protrusion, and the other is provided with a second slot, wherein the second protrusion is locked in the second slot. Thus, the second protrusion and the second slot are cooperatively connected, making it easy to clamp the first connector and the clamping member together.

[0013] In certain embodiments, the first connector includes a connector portion and a stopper disposed on the connector portion. The connector portion is disposed through the wall, and the stopper is configured to abut against a side of the wall facing away from the connector assembly. Thus, the stopper can limit movement of the first connector toward the other side of the wall. The stopper cooperates with the retaining member to ensure a stable installation of the connector assembly on the wall.

[0014] The energy storage system of the embodiment of the present invention includes a wall and the connector device described in any one of the above embodiments, and the connector device is arranged on the wall.

[0029] See also Figure 1The energy storage system 1000 of the embodiment of the present application includes a wall 200 and a connector device 100, and the connector device 100 is arranged on the wall 200. Specifically, the wall 200 can be a component of the energy storage system 1000 used to isolate different compartments, and the wall 200 can be made of materials such as alloys. The connector device 100 can be passed through the wall 200 and can connect pipelines located in different compartments. The energy storage system 1000 may include multiple battery cells and a cooling system. The cooling system can cool the battery cells through the liquid flowing in the pipeline, thereby improving the charging and discharging efficiency of the battery cells.

[0030] See also Figure 2 and Figure 3 The connector device 100 of the embodiment of the present application includes a first connector 10 and a connector assembly 20. The first connector 10 is used to pass through the wall 200 of the energy storage system 1000. The connector assembly 20 includes a first seal 21, a second connector 22, a clamping member 23 and a sleeve 24. The first seal 21 is sleeved on the first connector 10 and is used to abut against the wall 200. The second connector 22 is docked with the first connector 10 and connected to the sleeve 24. The clamping member 23 is clamped with the first connector 10. The sleeve 24 is sleeved on the first connector 10 and one end presses against the first seal 21. The clamping member 23 abuts against the sleeve 24 to limit the movement of the sleeve 24 relative to the first connector 10, thereby limiting the movement of the connector assembly 20 relative to the first connector 10.

[0031] In the joint device 100 of the above embodiment, the first sealing member 21 is sleeved on the first joint 10, so that the gap between the first joint 10 and the wall 200 can be sealed in the radial direction of the first joint 10. In addition, the first sealing member 21 is used to abut against the wall 200, thereby sealing the gap between the first joint 10 and the wall 200 in the axial direction of the first joint 10, and the structure is simple; furthermore, the joint assembly 20 is clamped with the first joint 10 through the clamping member 23 to limit the movement of the joint assembly 20 relative to the first joint 10, so that the assembly of the first joint 10 and the joint assembly 20 is convenient, which is conducive to improving the efficiency of installing the joint device 100 on the wall 200.

[0032] Specifically, the first connector 10 can be a male connector and can be made of a metal material such as an alloy. It is understood that the first connector 10 has a hollow structure. The connector assembly 20 is a component used to connect to the first connector 10. The connector assembly 20 and the first connector 10 are assembled together from opposite sides of the wall 200, thereby allowing the connector device 100 to be installed on the wall 200.

[0033] The first seal 21 can be made of a deformable material such as fluororubber to achieve a sealing function. The first seal 21 is mounted on the first joint 10, so that the first seal 21 can seal the gap between the first joint 10 and the wall 200 in the radial direction. The first seal 21 abuts against the wall surface of the wall 200, so that the first seal 21 can seal the gap between the first joint 10 and the wall 200 in the axial direction. After the joint device 100 is installed on the wall 200, the compartments on both sides of the wall 200 are sealed and isolated.

[0034] The second connector 22 can be a female connector, and the inner diameter of the second connector 22 can be larger than the outer diameter of the first connector 10, so that the second connector 22 can be inserted outside the first connector 10. Of course, the outer diameter of the second connector 22 can be smaller than the inner diameter of the first connector 10, so that the second connector 22 can be inserted into the first connector 10. The second connector 22 can be made of a material such as plastic, so that the second connector 22 can be easily connected to the first connector 10.

[0035] The clamping member 23 can be an annular member and is sleeved on the first connector 10 to be clamped together with the first connector 10. After the clamping member 23 is clamped with the first connector 10, the entire connector assembly 20 can remain stationary relative to the first connector 10.

[0036] The sleeve 24 presses against the first sealing member 21, which can stabilize the position of the first sealing member 21 and facilitate the first sealing member 21 to achieve the sealing function. Furthermore, based on the clamping connection between the clamping member 23 and the first joint 10, the clamping member 23 abuts against the sleeve 24, so that the entire joint assembly 20 can be fixed relative to the position of the first joint 10.

[0037] The sleeve 24 is cylindrical, with an inner diameter greater than the outer diameter of the first joint 10. The sleeve 24 presses against the first seal 21, preventing it from moving away from the wall 200. Furthermore, the retaining member 23 abuts against the sleeve 24, limiting its movement away from the wall 200. Furthermore, due to the interaction between the wall 200 and the first seal 21, the sleeve 24 is prevented from moving further toward the wall 200, thereby securing its position. The connection between the second joint 22 and the sleeve 24 maintains a stable position relative to the sleeve 24.

[0038] That is, under the interaction of the first joint 10 , the wall 200 , the first sealing member 21 , the sleeve 24 , the retaining member 23 and the second joint 22 , the first joint 10 and the joint assembly 20 can maintain a stable connection.

[0039] In the embodiment of the present application, the first sealing member 21 is located at the end of the sleeve 24. The first sealing member 21 and the sleeve 24 do not need to be sleeved together, which reduces the diameter of the joint assembly 20 and makes the volume of the joint device 100 smaller.

[0040] See also Figure 4-Figure 6 In certain embodiments, the retaining member 23 includes a ring body 231 and a protrusion 232 that protrudes radially from the ring body 231. The ring body 231 is engaged with the first connector 10, and the protrusion 232 abuts against a side of the sleeve 24 axially away from the first sealing member 21. Thus, the retaining member 23 is engaged with the first connector 10 through the ring body 231, and the protrusion 232 abuts against one side of the sleeve 24 axially, thereby maintaining a stable position of the sleeve 24 relative to the first connector 10, thereby securing the entire connector assembly 20 relative to the first connector 10.

[0041] Specifically, the ring body 231 is generally annular and can be either open or closed. The protrusion 232 can be connected to the ring body 231 to form a closed ring, making the retaining member 23 more easily deformable and easily fitted onto the first connector 10. For example, the ring body 231 and the protrusion 232 can both be made of flat sheet material. There can be two protrusions 232, one located on opposite sides of the ring body 231.

[0042] Since the protrusion 232 abuts against one axial side of the sleeve 24 , the axial movement of the sleeve 24 relative to the first connector 10 along the first connector 10 can be restricted.

[0043] like Figure 6 As shown, in some embodiments, the socket 24 is provided with a notch 241 that passes through the side wall of the socket 24, the protrusion 232 is passed through the notch 241 and abuts against the bottom surface 242 of the notch 241, the bottom surface 242 is axially facing the socket 24, and the second joint 22 is located on the side of the ring body 231 away from the first sealing member 21.

[0044] In this way, the notch 241 can reduce the interference between the second joint 22 and the clamping member 23 , and can make the position where the clamping member 23 and the first joint 10 are clamped close to the wall 200 , thereby shortening the axial length of the first joint 10 .

[0045] Specifically, the notch 241 extends from the end of the sleeve 24 away from the wall 200, and the protrusion 232 can be retained in the notch 241. The bottom surface 242 of the notch 241 is the bottom surface 242 of the notch 241 located axially adjacent to the wall 200. The protrusion 232 presses against the bottom surface 242 of the notch 241, thereby limiting the movement of the sleeve 24 relative to the first connector 10. The second connector 22 is located on the side of the ring 231 away from the first sealing member 21, ensuring that the second connector 22 and the retaining member 23 do not interfere with each other, facilitating the formation of a single, integrated connector assembly 20.

[0046] See also Figure 5-Figure 7 In some embodiments, the second connector 22 is engaged with the sleeve 24 and presses the retaining member 23 along the axial direction of the first connector 10. Thus, the second connector 22 and the sleeve 24 are connected by a snap connection, making them easy to disassemble. Furthermore, the second connector 22 presses the retaining member 23 along the axial direction of the second connector 24, thereby limiting the axial position of the retaining member 23 and ensuring a secure connection between the first connector 10 and the connector assembly 20.

[0047] See also Figure 3 and Figure 6 In some embodiments, one of the second connector 22 and the socket 24 has a first protrusion 221, and the other has a first slot 222, and the first protrusion 221 is engaged with the first slot 222. For example, the second connector 22 has a first protrusion 221, and the socket 24 has a first slot 222; for another example, the second connector 22 has a first slot 222, and the socket 24 has a first protrusion 221.

[0048] In this manner, the first protrusion 221 and the first engaging groove 222 cooperate to connect the second connector 22 and the socket 24, making it easier to snap together. Specifically, there are multiple first protrusions 221 and multiple first engaging grooves 222, each of which is spaced apart along the circumference of the second connector 22, with each of the first protrusions 221 and the first engaging grooves 222 corresponding to each other. The first engaging groove 222 can be a square groove, and the cross-section of the first protrusion 221 along the second axial direction can be triangular, making it easier for the first protrusion 221 to snap into the first engaging groove 222.

[0049] See also Figure 6 In some embodiments, a groove 211 is provided on the side of the first sealing member 21 facing away from the wall 200, and one end of the sleeve 24 is inserted into the groove 211. Thus, with one end of the sleeve 24 inserted into the groove 211, the sleeve 24 can more stably press against the first sealing member 21, thereby improving the sealing effect of the first sealing member 21.

[0050] Specifically, the groove 211 is an annular groove, and radial sides of the groove 211 can contact one end of the sleeve 24 , so that the position between the first sealing member 21 and the sleeve 24 remains stable.

[0051] In some embodiments, a second sealant 25 is provided between the first joint 10 and the second joint 22. The second sealant 25 seals the gap between the first joint 10 and the second joint 22. In this way, the second sealant 25 can improve the sealing effect between the first joint 10 and the second joint 22.

[0052] Specifically, when the outer diameter of the first joint 10 is smaller than the inner diameter of the second joint 22, the second sealing member 25 is sleeved on the first joint 10 and positioned between the outer circumferential surface of the first joint 10 and the inner circumferential surface of the second joint 22. When the outer diameter of the first joint 10 is larger than the inner diameter of the second joint 22, the second sealing member 25 is sleeved on the second joint 22 and positioned between the outer circumferential surface of the second joint 22 and the inner circumferential surface of the first joint 10.

[0053] See also Figure 3 、 Figure 6 and Figure 7 In some embodiments, one of the first connector 10 and the retaining member 23 has a second protrusion 11, and the other has a second retaining groove 12, and the second protrusion 11 is retained in the second retaining groove 12. For example, the first connector 10 has a second protrusion 11, and the retaining member 23 has a second retaining groove 12; for another example, the first connector 10 has a second retaining groove 12, and the retaining member 23 has a second protrusion 11.

[0054] In this way, the second protrusion 11 and the second latching groove 12 are cooperatively connected, making it easy to latch the first connector 10 and the retaining member 23 together. Specifically, there can be multiple second protrusions 11, which are arranged at intervals along the circumference of the first connector 10. The number of second latching groove 12 can be one, and the second groove 211 can be annular as a whole. The multiple second protrusions 11 can be latched at different positions of the second latching groove 12.

[0055] See also Figure 5 In some embodiments, the first connector 10 includes a connector portion 13 and a stopper 14 disposed on the connector portion 13. The connector portion 13 is disposed through the wall 200, and the stopper 14 is configured to abut against the wall 200. Thus, the stopper 14 can limit the movement of the first connector 10 toward the other side of the wall 200. The stopper 14 cooperates with the retaining member 23, allowing the connector device 100 to be stably mounted on the wall 200.

[0056] Specifically, the joint portion 13 is tubular, the stopper portion 14 is annular and disposed on the outer circumference of the joint, and the stopper portion 14 may extend along the circumference of the joint portion 13. The joint portion 13 and the stopper portion 14 may be an integral structure.

[0057] In one embodiment, an installation process of the connector device 100 is as follows: the first sealing member 21 is installed at one end of the socket member 24 by interference fit or bonding, and then the clamping member 23 is installed in the socket member 24 so that the protrusion 232 of the clamping member 23 is clamped in the notch 241 of the socket member 24, and then the second connector 22 is clamped on the socket member 24 to form a connector assembly 20 as a whole; then the first connector 10 is passed through the wall 200 from one side of the wall 200, and the connector assembly 20 is inserted into the first connector 10 from the other side of the wall 200. After the clamping member 23 is clamped with the first connector 10, the installation of the connector device 100 is completed, and the installation efficiency of the connector device 100 is relatively high.
