The power cable quick connector device 100 and the battery pack quick fixing device 200 are respectively provided with a power cable and a battery pack device 1100 on a vibrating table 900 in an environment bin 800, and two power cables respectively connected with the charge and discharge device 1000 and the battery pack device 1100 are connected and disconnected through the power cable quick connector device 100, so that the charge and discharge device 1000 and the battery pack device 1100 are connected and disconnected.
The safety house 500 is disposed opposite to the environmental chamber 800, and the environmental chamber door 300 mounted on the environmental chamber 800 is disposed coaxially opposite to the safety house door 700 mounted on the safety house 500.

When the battery pack device 1100 is self-ignited or has a self-ignition tendency, the control device 400 controls the devices to act, so that the two power cables are disconnected, the battery pack quick fixing device 200 is disconnected, the environment cabin automatic door 300 and the safety cabin automatic door 700 are synchronously opened, the rolling device 600 drags the battery pack device 1100 into the safety cabin 500 from the environment cabin 800, and the environment cabin automatic door 300 and the safety cabin automatic door 700 are closed.
In this embodiment, as shown in fig. 2, the power cable quick connector device 100 mainly comprises a cable female clamp 101, an electromagnet 102, a cable male clamp 103, a first return spring 104, a spring end gasket 105, a cable male clamp boss 106, a wedge boss 107, and a wedge spring piece 108.
The cable head clamp 101 is mounted to the vibration table 900 by a plurality of bolts 1200, and a cable head 1002 provided at an end of a first power cable 1001 connected to the charging and discharging device 1000 is inserted into the cable head clamp 101 and fixed in the cable head clamp 101 by upper and lower two bolts 1200. A cable male 1101 provided at an end of a second power cable 1102 connected to a battery pack 1103 is inserted into the cable male jig 103 and fixed in the cable male jig 103 by upper and lower two bolts 1200.
The upper side and the lower side of the cable mother head clamp 101 are symmetrically provided with an outer groove and a side groove. Wherein the outer groove is provided with a top opening and a bottom side opening, and the two electromagnets 102 are respectively fixed in the top openings of the outer grooves on the upper side and the lower side of the cable mother head clamp 101 through bolts 1200, and the on-off of the two electromagnets is controlled through the control device 400. The wedge-shaped boss 107 is arranged at the opening at the bottom side of the outer groove, when the cable female clamp 101 is combined with the cable male clamp 103, the wedge-shaped boss 107 is matched with the wedge-shaped elastic sheet 108 arranged at the end part of the cable male clamp 103 for extrusion, when the cable female clamp 101 and the cable male clamp 103 are to be loosened, the electromagnet 102 is electrified to attract the wedge-shaped elastic sheet 108 to deform, and the extrusion with the wedge-shaped boss 107 is loosened. The side groove is opened at the end part side of the cable female clamp 101, in the side groove, the left end of the first return spring 104 is fixed on the cable female clamp 101, the right end of the first return spring 104 is fixed with a spring end gasket 105, the spring end gasket 105 is used for being connected with a cable male clamp boss 106 at the end part of the cable male clamp 103, and the cable female clamp 101 and the cable male clamp 103 can be separated through the elasticity of the first return spring 104.
When the cable female jig 101 is combined with the cable male jig 103, the cable male jig 103 is inserted into the cable female jig 101, and simultaneously the cable male 1101 is inserted into the cable female 1002 for connection. To avoid a poor fit between the male cable head 1101 and the female cable head 1002, the male cable head 1101 and the female cable head 1002 are connected and then the bolt 1200 is locked completely.
When the cable male clamp 103 is inserted into the cable female clamp 101, the cable male clamp boss 106 pushes the spring end gasket 105 to compress the first return spring 104, the wedge surface of the wedge-shaped elastic sheet 108 of the cable male clamp 103 is matched with the wedge surface of the wedge-shaped boss 107 of the cable female clamp 101, and along with the movement of the cable male clamp 103, the wedge-shaped elastic sheet 108 is elastically deformed until the wedge-shaped elastic sheet 108 ends clamp the wedge-shaped boss 107, so that an anti-loose effect is achieved.
When the cable female clamp 101 and the cable male clamp 103 are to be disconnected, the control device 400 controls the coil of the electromagnet 102 to be electrified, the electromagnet 102 generates magnetic force to attract the wedge-shaped elastic sheet 108 to generate enough deformation, so that the wedge-shaped elastic sheet 108 does not clamp the wedge-shaped boss 107 any more. The cable male jig 103 moves rightward under the elastic force of the first return spring 104, and is disengaged from the cable female jig 101, thereby disengaging the cable female 1002 with the cable male 1101.
In this embodiment, in order to ensure that the wedge spring 108 can be completely separated, as shown in fig. 3, the gap t1 between the wedge spring 108 and the electromagnet 102 should be larger than the protrusion height t2 of the wedge boss 107 at the end of the wedge spring 108, and the electromagnet 102 selects a suitable specification according to the deformation force of the wedge spring 108, so as to ensure that the magnetic force of the wedge spring 108 can cause the wedge spring 108 to generate enough deformation. In order to ensure reliable locking of the male cable 1101 and the female cable 1002 during vibration, the stiffness of the wedge spring 108 should be sufficiently high to ensure that deformation due to vibration does not occur, resulting in disengagement of the wedge spring 108. The spring force of the first return spring 104 should be large enough to allow the cable male clamp 103 to be effectively disengaged. In this embodiment, the magnetic force generated by the electromagnet 102 is greater than the elastic force of the wedge spring 108 and the friction force between the wedge spring 108 and the wedge boss 107. Preferably, the protrusion height t2 of the wedge boss 107 is 2mm, the rigidity of the wedge spring 108 is 30-50N/mm, the elastic force of the wedge spring 108 is about 60-100N, the friction force between the wedge spring 108 and the wedge boss 107 is about 30-60N, and the electromagnetic force generated by the electromagnet 102 is 200-250N. The elastic force of the first return spring 104 is 100-200N.
The battery pack 1103 in the battery pack apparatus 1100 is fixed inside the battery pack frame 1104 by screws.
