The liquid metals stored in first fluid reservoir 70 can be pumped into the first sealing room 21 and the second sealing by work, first pump housing 60
In room 33, so as to realize the charge function of charging unit 10, when detecting that first pump housing 60 can be by when needing to draw guns
Liquid metals in one sealing room 21 and the second sealing room 33 is pumped back in the first fluid reservoir 70, can control liquid at any time in this way
Metal flows in and out the first sealing room 21 and the second sealing room 33, so as to improve the service life of charging unit 10.By
This, can effectively mitigate the weight of charging socket 65 and charging gun 66, can mitigate the weight for lifting charging gun 66, Che Duanke with
The weight for mitigating the vehicle of driving status, realizes the lightweight of vehicle.It is provided between first pump housing 60 and the first fluid reservoir 70
First filter 80, first filter 80 can play a role in filtering.
As shown in figures 11-13, charging unit 10 can also include: control valve 90, and the setting of control valve 90 is in the first sealing
Between room 21 and the pump housing 73, there is control valve 90 control liquid metals to flow in and out the first sealing room 21 and the second sealing room 33
Effect, when charging unit 10 work when, open control valve 90, then liquid metals is pumped into the first sealing room 21 by the pump housing 73
In the second sealing room 33, when charging unit 10 does not work, control valve 90 is closed, then liquid metals is pumped back to by the pump housing 73
In first fluid reservoir 70, setting can make simple, convenient in this way, so as to increase customer satisfaction degree.It needs to illustrate
It is that the exit of the first fluid reservoir 70 can also be arranged in control valve 90.
As shown in Fig. 6-Figure 10, charging unit 10 is set as charging socket 65 or charging unit 10 can be charging gun
66, that is to say, that the charging unit 10 of such setting can be adapted for charging socket 65, be readily applicable to charging gun 66.Such as
Shown in Fig. 6 and Fig. 8, during Vehicular charging, after charging socket 65 is docked with charging gun 66, charging socket 65 and charging gun 66
Both ends connecting terminal 2 contacts with each other, and the purpose to Vehicular charging may be implemented in this way.
Furthermore it is possible to charging socket 65 and charging gun 66, wherein any one connecting terminal 2 is arranged to liquid metal
Terminal, then another connecting terminal 2 is arranged to solid terminal, it is to be understood that if the terminals of charging socket 65
Son 2 is arranged to liquid metal terminal, the connecting terminal 2 of charging gun 66 is just arranged to solid terminal, if charging gun 66
