[0033] The following is for reference. Figure 1-Figure 4 Description of the liquid cooling plate assembly 100 according to an embodiment of the present utility model.

[0034] According to a first aspect embodiment of the present invention, a liquid cooling plate assembly 100 includes a flow divider 10, a liquid cooling plate 20, and a connecting pipe 30. The liquid cooling plate 20 has a liquid cooling pipe 21, and the connecting pipe 30 is connected between the flow divider 10 and the liquid cooling plate 20. The liquid cooling pipe 21 has an opening 22 facing the connecting pipe 30, and the end of the connecting pipe 30 is inserted into the liquid cooling pipe 21 through the opening 22, so that the connecting pipe 30 communicates with the liquid cooling pipe 21.

[0035] The coolant flowing out of the distributor 10 flows to the liquid cooling plate 20 through the connecting pipe 30. The liquid cooling plate 20 is located between two adjacent battery cells 50 and is used to radially cool or heat the battery cells 50. The coolant after exchanging heat with the battery cells 50 flows back into the distributor 10 through the connecting pipe 30.

[0036] The liquid cooling plate assembly 100 also includes a locking structure 40. During use, the liquid cooling pipe 21 and the connector of the connecting pipe 30 may leak due to vibration, aging and other factors. The locking structure 40 is set between the connecting pipe 30 and the liquid cooling pipe 21 to increase the connection strength between the connecting pipe 30 and the liquid cooling pipe 21 and prevent the connecting pipe 30 and the liquid cooling pipe 21 from shaking due to external vibration, which would cause gaps to form between the connecting pipe 30 and the liquid cooling pipe 21 and allow coolant to flow out from the gaps.

[0037] The locking structure 40 includes a locking member 41 and a locking ring 42. The locking member 41 is located in the liquid cooling pipe 21, and the locking ring 42 is located in the connecting pipe 30. The locking ring 42 has a locking groove 421 that cooperates with the locking member 41. After the end of the connecting pipe 30 is inserted into the liquid cooling pipe 21 through the opening 22, the locking member 41 cooperates with the locking groove 421 to lock the connecting pipe 30 and the liquid cooling pipe 21. Through the cooperation of the locking member 41 and the locking groove 421, the locking method between the connecting pipe 30 and the liquid cooling pipe 21 can be simple and easy to operate.

[0038] For example, the locking member 41 is a connecting rod provided on the outer peripheral wall of the liquid cooling pipe 21. One end of the connecting rod has a locking hook 411. When the end of the connecting pipe 30 is inserted into the liquid cooling pipe 21 through the opening 22, the outer peripheral wall of the locking ring 42 pushes the locking member 41 to move outward. After the connecting pipe 30 is installed in place, the locking member 41 is reset, and the locking hook 411 of the locking member 41 is located in the locking groove 421.

[0039] According to the liquid cooling plate assembly 100 of this utility model embodiment, the end of the connecting pipe 30 is inserted into the liquid cooling pipe 21 through the opening 22. The locking structure 40 is locked between the connecting pipe 30 and the liquid cooling pipe 21. The locking structure 40 includes a locking member 41 provided on the liquid cooling pipe 21 and a locking ring 42 provided on the connecting pipe 30. The locking member 41 and the locking groove 421 of the locking ring 42 cooperate. By setting the locking structure 40, the connection strength between the connecting pipe 30 and the liquid cooling pipe 21 can be increased, and leakage between the connecting pipe 30 and the liquid cooling pipe 21 due to external vibration and other factors can be avoided. Moreover, the cooperation between the locking member 41 and the locking groove 421 makes the locking method between the connecting pipe 30 and the liquid cooling pipe 21 simple and easy to operate.

[0040] According to some embodiments of the present invention, referring to Figure 2-Figure 3The locking structure 40 also includes a rotating shaft 43, which is connected to the liquid cooling pipe 21. The end of the locking member 41 facing the liquid cooling pipe 21 has a through hole, through which the rotating shaft 43 passes. The locking member 41 can rotate relative to the rotating shaft 43. After the end of the connecting pipe 30 is inserted into the liquid cooling pipe 21 through the opening 22, the locking member 41 rotates around the rotating shaft 43 so that the locking member 41 is engaged in the locking groove 421. By setting the rotating shaft 43, the locking member 41 can be easily engaged in the locking groove 421.

[0041] For example, connecting plates 431 are provided at both ends of the rotating shaft 43. The connecting plates 431 are connected to the liquid cooling pipe 21. The connecting plates 431 have through holes that allow the rotating shaft 43 to pass through, so that the rotating shaft 43 is connected to the liquid cooling pipe 21.

[0042] According to some embodiments of the present invention, referring to Figure 2-Figure 3 The locking component 41 includes a locking hook 411, which cooperates with the locking groove 421. After the end of the connecting pipe 30 is inserted into the liquid cooling pipe 21 through the opening 22, the locking hook 411 is locked into the locking groove 421, which can lock the connecting pipe 30 and the liquid cooling pipe 21.

[0043] For example, the locking member 41 includes a connecting rod and a locking hook 411, with one end of the connecting rod connected to the pivot 43 and the other end connected to the locking hook 411.

[0044] According to some embodiments of the present invention, referring to Figure 2-Figure 3 Multiple locking elements 41 are provided, and the number of locking grooves 421 corresponds to the number of locking elements 41. Multiple locking elements 41 are arranged at intervals along the circumference of the liquid cooling pipeline 21. After the multiple locking elements 41 are locked with the multiple locking grooves 421, the liquid cooling pipeline 21 and the connecting pipe 30 can be locked and fixed at multiple positions in the circumference, which can further increase the connection strength between the connecting pipe 30 and the liquid cooling pipeline 21.

[0045] According to some embodiments of the present invention, referring to Figures 2-4 The locking structure 40 also includes a fixing ring 44, which is sleeved on the outer periphery of the locking member 41 to limit the locking member 41 so that the locking member 41 cannot be turned outward, thereby preventing the locking member 41 from disengaging from the locking groove 421.

[0046] According to some embodiments of the present invention, referring to Figures 2-4 The end face of the liquid cooling pipe 21 is spaced apart from the end face of the locking ring 42. The fixing ring 44 is interference-fitted between the end face of the liquid cooling pipe 21 and the end face of the locking ring 42. The fixing ring 44 provides an upward support force for the locking ring 42, so that the locking ring 42 remains stable under the pressure of the locking member and the support of the fixing ring 44. At the same time, the fixing ring 44 also provides a seal between the connecting pipe 30 and the liquid cooling pipe 21.

[0047] The retaining ring 44 has a relief groove 441 for the locking member 41. The locking member 41 can extend to the outer periphery of the connecting pipe 30 through the relief groove 441, so that the locking member 41 can cooperate with the locking groove 421.

[0048] According to some embodiments of the present invention, referring to Figures 2-4 The retaining ring 44 is an elastic element with a certain degree of elasticity. When the joint between the connecting pipe 30 and the liquid cooling pipe 21 is subjected to vibration, the retaining ring 44 can absorb a certain amount of vibration. The elasticity of the retaining ring 44 increases the buffering force between the connecting pipe 30 and the liquid cooling pipe 21 during vibration.

[0049] For example, the retaining ring 44 can be made of silicone or rubber.

[0050] When the connecting pipe 30 is inserted into the liquid cooling pipe 21, the retaining ring 44, due to its elasticity, can be fitted onto the outer peripheral wall of the liquid cooling pipe 21. After the locking member 41 is engaged with the locking groove 421, the retaining ring 44 is pulled, so that the retaining ring 44 is fixed between the end face of the liquid cooling pipe 21 and the end face of the locking ring 42. Due to its own elastic force, the retaining ring 44 can be fitted onto the outer peripheral wall of the connecting pipe 30.

[0051] According to some embodiments of the present invention, referring to Figure 4 The end of the connecting pipe 30 facing the liquid cooling pipe 21 is provided with a limiting rib 31. The limiting rib 31 abuts against the inner wall of the liquid cooling pipe 21. After the end of the connecting pipe 30 is inserted into the liquid cooling pipe 21 through the opening 22, the limiting rib 31 can increase the friction between the outer peripheral wall of the connecting pipe 30 and the inner wall of the liquid cooling pipe 21, which can prevent the connecting pipe 30 from detaching from the liquid cooling pipe 21.

[0052] For example, the limiting rib 31 can be in the shape of an inverted triangle, which makes it easier for the end of the connecting tube 30 to be inserted into the liquid cooling pipe 21. When the connecting tube 30 is pulled out of the liquid cooling pipe 21, the limiting rib 31 can increase the friction between the outer peripheral wall of the connecting tube 30 and the inner wall of the liquid cooling pipe 21, making it difficult for the connecting tube 30 to be pulled out of the liquid cooling pipe 21.

[0053] According to some embodiments of the present invention, referring to Figure 1-Figure 2 The connecting pipe 30 includes an inlet connecting pipe 32 and an outlet connecting pipe 33. The liquid cooling pipe 21 includes an inlet pipe 211 and an outlet pipe 212. The locking structure 40 is locked between the inlet connecting pipe 32 and the inlet pipe 211, and between the outlet connecting pipe 33 and the outlet pipe 212, thereby increasing the connection strength between the inlet connecting pipe 32 and the inlet pipe 211, and between the outlet connecting pipe 33 and the outlet pipe 212.

[0054] The battery according to the second aspect of the present invention includes: a plurality of battery cells 50; and a liquid cooling plate assembly 100 according to the first aspect of the present invention, wherein the liquid cooling plate 20 is located between two adjacent battery cells 50 and is used to exchange heat between the battery cells 50.

[0055] According to the battery of this utility model embodiment, by setting the above-mentioned liquid cooling plate assembly 100, the connection strength between the connecting pipe 30 and the liquid cooling pipe 21 can be increased, and leakage between the connecting pipe 30 and the liquid cooling pipe 21 due to external vibration and other factors can be avoided, thereby increasing the safety of the battery.
