Preferably, as shown in fig. 4, a second hole type hanger 35 is provided at the rear end of the battery case 3, and a second mounting hole is provided in the second hole type hanger 35. And correspondingly, the battery detaching system 4 further comprises a second fixing device 44, the second fixing device 44 is arranged on the chassis 1 and is movably connected with the second hole-type hanging lug 35 of the battery box 3 up and down, for example, a bolt or a pin shaft is inserted into the second mounting hole to limit the battery box 3 in the X, Y direction, so that the mounting of the battery box 3 can be more stable. The second fixing device 44 may have the same function and structure as the first fixing device 42, and is used to adjust the relative sliding position of the sliding type hanging lug 32 and the mounting seat 41 when the battery 2 is in thermal runaway, so that the battery box 3 slides out of the mounting seat 41 to be separated from the vehicle body. In order to enable the sliding type lug of the battery box 3 to slide out of the mounting seat 41, the driving directions of the first fixing device 44 and the second fixing device 45 can be the same corresponding to the hole type lugs at the front end and the rear end of the battery box 3, for example, the first fixing device 44 is driven forward, the second fixing device 45 is also driven forward, so that the battery box 3 slides forward relative to the mounting seat 41 and is separated from the vehicle body.
In an embodiment, the fixing means may be implemented by means capable of performing both reciprocating and fixing functions. For example, the fixing device may include a hydraulic fixing device, as shown in fig. 4 or 5, the hydraulic fixing device includes a hydraulic cylinder 421, a limit beam 422 and a pin 423, the hydraulic cylinder 421 is disposed on the chassis 1, and the hydraulic cylinder 421 includes a cylinder 4211 and a piston 4212; the limit beam 422 is connected with the piston 4212 and is provided with a first through hole 4221 corresponding to the first mounting hole 331 of the first hole type hanging lug 33; the pin 423 may be inserted into the aligned first mounting hole 331 and the first through hole to fix the position-limiting beam 422 and the first hole-type hanging lug 33. The limit beam 422 can be driven by the piston 4212 to reciprocate in the X direction and be fixed at a specific position. When the piston 4212 is stationary, the displacement of the battery case 3 in the X direction can be restricted, thereby fixing the battery case 3. Note that the pin 423 does not restrict the displacement of the battery case 3 in the Z direction.
Further, as shown in fig. 6, which is a schematic diagram of the male end of the connector and the female end of the connector matching according to an embodiment of the present invention, a plug hole 341 is disposed on the female end 34 of the connector. The male connector end 43 is provided with a plug 431. In an embodiment, the male connector end 43 may control the extension and retraction of the plug 431 to achieve quick connection and disconnection with the female connector end 34.
Referring to fig. 7-9, which are schematic diagrams illustrating the cooperation of battery boxes with different cross sections and battery release systems provided with a set of fixing devices, specifically, the specific implementation manner of releasing the battery box 3 from the vehicle body is as follows: in the driving process of the vehicle 100, the temperature sensor 5 located at the battery 2 monitors the battery temperature in real time, and transmits a temperature signal to the vehicle control unit 6 located on the vehicle 100, when the vehicle control unit 6 judges that the battery temperature is higher than a preset temperature threshold, it indicates that the battery 2 is in thermal runaway, and at this time, the vehicle control unit 6 transmits an execution signal to the connector male end 43 and the hydraulic fixing device 42. First, the male connector end 43 controls the plug 431 to retract and quickly separate from the female connector end 34. The hydraulic fixing device 42 then pushes the limit beam 422 to move through the piston 4212, so that the battery box 3 slides relative to the mounting seat 41. When the slide type lug 32 slides out of the fixed range of the mount 41, the entire battery case 3 falls down due to its own weight. The pin 423 used for fixing the front end of the battery box 3 and the limiting beam 422 of the hydraulic fixing device 42 can only limit the displacement of the battery box 3 in the X and Y directions, and is not constrained in the Z direction. Thereby ensuring that the battery box 3 is quickly separated from the vehicle body under the action of gravity. The vehicle body of the vehicle 100 continues to travel forward for a distance due to its own inertia or other power sources, thereby being away from the battery box 3 where thermal runaway has occurred, ensuring passenger safety. In the embodiment, the separation process of the battery box 3 and the battery separation system 4 can be realized fully automatically, and is simple and timely.
Further, the utility model discloses vehicle 100, when battery 2 trouble or need overhaul change battery box 3, also can realize that battery box 3 dismantles fast and the installation. The specific implementation mode of installing the battery box 3 is as follows: the battery box 3 is placed at the bottom of the vehicle 100, and lifted by the lifting device, so that the sliding type hanging lug 32 of the battery box 3 is at the same level as the mounting seat 41 fixed on the chassis 1, and the pin 423 on the limiting beam 422 is aligned with the mounting hole on the first hole type hanging lug 33. So that the pin 423 is accurately inserted into the mounting hole of the first hole type hanger 33 when lifting the battery case 3. Then, the sliding lug 32 is slid into engagement with the mounting seat 41 by contraction of the piston 4212, and the piston 4212 is fixed at an appropriate position. After the battery box 3 is installed in place, the control connector male end 43 controls the plug 431 to extend and insert into the plug hole 341 to connect with the connector female end 34, and the installation of the battery box 3 is completed.
