The third external thread 221 can also be threadedly engaged with the first internal thread 31 of the moving sleeve 30, so that the reliability of the cooperation between the moving sleeve 30 and the second cooling line 220 can be ensured, and the moving sleeve 30 can be ensured. The tightness between the second cooling lines 220.
根据本申请的一个实施例,如图1和图4所示,驱动装置60包括:驱动电机61和传动螺纹杆62,传动螺纹杆62与驱动电机61相连,其中,移动套管30的外周形成有第二外螺纹,传动螺纹杆62与第二外螺纹螺纹配合,可以实现移动套管30相对第一冷却管路20的 轴向移动。可以理解的是,在驱动电机61工作时,传动螺纹杆62通过第二外螺纹驱动移动套管30旋转的同时轴向移动,从而可以实现第一冷却管路20和第二冷却管路220的对接。According to an embodiment of the present application, as shown in FIGS. 1 and 4, the driving device 60 includes a driving motor 61 and a driving threaded rod 62 connected to the driving motor 61, wherein the outer circumference of the moving sleeve 30 is formed. With a second external thread, the drive threaded rod 62 is threadedly engaged with the second external thread to effect axial movement of the moving sleeve 30 relative to the first cooling line 20. It can be understood that when the driving motor 61 is in operation, the driving threaded rod 62 is axially moved while the moving sleeve 30 is rotated by the second external thread driving, so that the first cooling line 20 and the second cooling line 220 can be realized. Docking.
如图1所示,第一充电连接件100还包括:封盖70,封盖70罩设在驱动电机61和传动螺纹杆62上,壳体上设置有开口,传动螺纹杆62的一部分伸入开口内。封盖70的设置一方面可以起到保护驱动电机61和传动螺纹杆62的作用,另一方面还可以起到固定驱动电机61的作用。As shown in FIG. 1 , the first charging connector 100 further includes a cover 70 that is disposed on the driving motor 61 and the transmission threaded rod 62. The housing is provided with an opening, and a part of the transmission threaded rod 62 extends into the housing. Inside the opening. The arrangement of the cover 70 serves to protect the drive motor 61 and the drive threaded rod 62 on the one hand and to fix the drive motor 61 on the other hand.
如图2所示,第一冷却管路20内设置有进液流道22和回液流道23。也就是说,在该第一冷却管路20内,可以实现进液和出液两个过程,这样可以使得第一充电连接件100结构简单,而且能够持续带走第一接线端子120所产生的热量。需要说明的是,第二冷却管路220内对应设置有进液流道22和回液流道23,以便于与第一冷却管路20对接。其中,第一冷却管路20和第二冷却管路220的结构可以大体相同。As shown in FIG. 2, an inlet flow path 22 and a liquid return flow path 23 are provided in the first cooling line 20. That is to say, in the first cooling line 20, two processes of liquid inlet and outlet can be realized, which can make the first charging connector 100 simple in structure and can continuously take away the first terminal 120. Heat. It should be noted that the second cooling circuit 220 is correspondingly provided with an inlet flow channel 22 and a liquid return flow channel 23 to facilitate docking with the first cooling pipe 20 . Wherein, the structures of the first cooling pipe 20 and the second cooling pipe 220 may be substantially the same.
其中,如图1和图2所示,进液流道22和回液流道23内分别设置有单向通水膜片25。单向通水膜片25可以使得流通后的水不会出现回流漏液现象。防止在第一充电连接件100和第二充电连接件分开时候出现漏液问题,从而可以提高第一冷却管路20和第二冷却管路220的布置安全性。Here, as shown in FIGS. 1 and 2, a unidirectional water-passing membrane 25 is disposed in each of the inlet flow path 22 and the liquid return flow path 23. The one-way water-passing membrane 25 can prevent the water after the circulation from leaking and leaking. The leakage problem occurs when the first charging connector 100 and the second charging connector are separated, so that the arrangement safety of the first cooling pipe 20 and the second cooling pipe 220 can be improved.
