Example 1
The different types of battery packs, when installed with an electric vehicle or charging device, typically use different locking mechanisms.

The different types of battery packs include differences in types of locking mechanisms of the battery packs on the corresponding electric vehicles, in addition to differences in types such as specifications and sizes of the battery packs.
The battery replacing equipment further comprises a control mechanism, the control mechanism is used for receiving the type of the locking mechanism of the battery pack to be disassembled and assembled, and the control mechanism is further used for controlling the corresponding disassembling and assembling mechanism to complete disassembling and assembling of the battery pack. For example, when the control mechanism receives that the type of the locking mechanism of the battery pack to be disassembled is the first locking mechanism, that is, the battery pack is the first battery pack, the control mechanism controls the first disassembling and assembling mechanism 1 to unlock or lock the first locking mechanism, so that the first battery pack can be disassembled or assembled; when the type of the locking mechanism of the battery pack to be disassembled and assembled received by the control mechanism is the second locking mechanism, the control mechanism controls the second disassembling and assembling mechanism 2 to unlock or lock the second locking mechanism, so that the second battery pack can be disassembled or assembled.
As shown in fig. 1, the battery replacement equipment further comprises a base 3, and the first disassembling and assembling mechanism 1 and the second disassembling and assembling mechanism 2 are detachably mounted on the base 3. Through the detachable connection among the first disassembling and assembling mechanism 1, the second disassembling and assembling mechanism 2 and the base 3, the battery replacing device can be independently provided with the first disassembling and assembling mechanism 1 or the second disassembling and assembling mechanism 2, so that the battery replacing device can be independently applied to the disassembling and assembling of the first battery pack or the second battery pack; the battery replacing device can also be simultaneously provided with the first disassembling and assembling mechanism 1 and the second disassembling and assembling mechanism 2, so that the battery replacing device can be compatible with the disassembling and assembling of the first battery pack and the second battery pack.
As shown in fig. 1, the positions of the first dismounting mechanism 1 and the second dismounting mechanism 2 on the base 3 are relatively determined. Relative to the first disassembling and assembling mechanism 1, the area where the second disassembling and assembling mechanism 2 is located is an avoidance area, namely the second disassembling and assembling mechanism 2 does not influence the action of disassembling and assembling the battery pack of the first disassembling and assembling mechanism 1; compared with the second disassembling and assembling mechanism 2, the area where the first disassembling and assembling mechanism 1 is located is an avoidance area, namely, the first disassembling and assembling mechanism 1 does not influence the action of disassembling and assembling the battery pack of the second disassembling and assembling mechanism 2.
In other embodiments, there may be a plurality of detaching mechanisms, and a plurality of detaching mechanisms correspond to battery packs locked by a plurality of different locking mechanisms. The number of the disassembling and assembling mechanisms is determined according to the number of the locking mechanisms which need to be compatible with the battery replacement equipment.
The multifunctional battery replacing equipment is applied to a battery replacing station, so that the battery replacing station can be compatible with the disassembly and assembly of various types of battery packs. As shown in fig. 2, the battery swapping station using the multifunctional battery swapping device includes a battery compartment 100, a first battery swapping device 200, and a second battery swapping device 300, where a first battery pack corresponding to a first locking mechanism and a second battery pack corresponding to a second locking mechanism are stored in the battery compartment 100.

The first battery replacement device 200 and the second battery replacement device 300 are set to be multifunctional battery replacement devices, so that the first battery replacement device 200 and the second battery replacement device 300 can be used for replacing the first battery pack or the second battery pack at the same time. When the battery pack to be replaced is the first battery pack, the second battery replacing device 300 can take out the fully charged first battery pack from the battery compartment 100 and wait on one side while the first battery replacing device 200 removes the first battery pack with insufficient power from the electric vehicle 400; after the first battery pack is detached by the first battery replacing device 200, the second battery replacing device 300 immediately mounts the first battery pack on the electric vehicle 400. When the battery pack to be replaced is the second battery pack, the second battery pack with insufficient power can be taken out of the battery compartment 100 by the second power exchanging device 300 and waits on one side while the first power exchanging device 200 removes the second battery pack with insufficient power from the electric vehicle 400; after the first battery replacing device 200 finishes disassembling the second battery pack, the second battery replacing device 300 immediately installs the second battery pack on the electric vehicle 400. Therefore, when the first battery replacing device 200 and the second battery replacing device 300 can be compatible with replacement of two battery packs, the battery replacing efficiency can be obviously improved.
The first battery replacement device 200 and the second battery replacement device 300 may also be provided with various disassembly and assembly mechanisms to deal with various types of battery packs of the battery replacement station.
Example 2
The structure of the multifunctional battery replacement device of embodiment 2 is substantially the same as that of embodiment 1, except that: the position between the first assembling and disassembling mechanism 1 and the second assembling and disassembling mechanism 2 can be adjusted through the avoiding mechanism. Namely, the battery replacing equipment is also provided with an avoiding mechanism, the idle dismounting mechanism is moved to an avoiding position, and the dismounting mechanism positioned at the avoiding position does not influence the actions of other dismounting mechanisms for dismounting the battery pack.
In actual needs for attachment and detachment, the first attachment and detachment mechanism 1 and the second attachment and detachment mechanism 2 may interfere with each other during attachment and detachment. At this time, when the first dismounting mechanism 1 performs the action of dismounting the battery pack, the second dismounting mechanism 2 needs to move to the avoiding position, so that the second dismounting mechanism 2 does not influence the dismounting action of the first dismounting mechanism 1; when the second disassembly and assembly mechanism 2 performs the action of disassembling and assembling the battery pack, the first disassembly and assembly mechanism 1 needs to be moved to the avoiding position, so that the first disassembly and assembly mechanism 1 does not influence the disassembly and assembly action of the second disassembly and assembly mechanism 2.
The avoidance mechanism of the present embodiment is shown in fig. 3. The avoiding mechanism 4 comprises a turnover body 41 and a rotating shaft 42, the turnover body 41 rotates around the axis of the rotating shaft 42 to realize turnover, the turnover body 41 is provided with a first mounting surface 411 and a second mounting surface 412 around the circumferential direction, a first dismounting mechanism 1 is mounted on the first mounting surface 411, a second dismounting mechanism 2 is mounted on the second mounting surface 412, and a dismounting mechanism which is idle in the turnover process of the turnover body 41 rotates to an avoiding position.

For another example, when the second mounting and dismounting mechanism 2 is used to mount and dismount a battery pack, the turning body 41 is turned over to turn the second mounting and dismounting mechanism 2 to the mounting and dismounting position, the first mounting and dismounting mechanism 1 is turned over to the avoiding position, the second mounting and dismounting mechanism 2 located at the mounting and dismounting position can mount and dismount the battery pack, and the first mounting and dismounting mechanism 1 located at the avoiding position does not affect the mounting and dismounting operation of the second mounting and dismounting mechanism 2.
In other embodiments, the number of the mounting surfaces of the turnover body can be several, each dismounting mechanism is independently mounted on one mounting surface, and the spare dismounting mechanism is rotated to the avoiding position by the turnover body in the turnover process. The number of the disassembling and assembling mechanisms is determined according to the number of the locking mechanisms which need to be compatible with the battery replacement equipment.

The structure of the multifunctional battery replacement device of embodiment 3 is substantially the same as that of embodiment 1, except that:

When the first battery pack is unlocked, the ejector rod 14 abuts against the unlocking position 505 of the lock link 501 and drives the lock link 501 to move, so that the lock tongue 503 is retracted to the outside of the lock groove 504; the first battery pack is forked by the first positioning fork 13, the upper plate 11 drives the first battery pack to move, so that the lock shaft of the first battery pack is moved out of the lock groove 504, and the first battery pack is unlocked. When the first battery pack is locked, the ejector rod 14 moves to a position where the ejector rod does not contact the lock connecting rod 501, the first positioning fork 13 forks the first battery pack, and the upper plate 11 drives the first battery pack to move, so that the lock shaft of the first battery pack enters the lock groove 504 and is locked.
The first disassembling and assembling mechanism 1 further comprises a second positioning fork 15, the second positioning fork 15 is fixed on the lower plate 12, and the second positioning fork 15 can be matched with a positioning block on the electric automobile, so that the lower plate 12 is relatively fixed with the electric automobile when the first battery pack is unlocked or locked.
As shown in fig. 4, 6 to 7, the battery replacement apparatus further includes a fixing plate 5, the second attachment/detachment mechanism 2 is fixed to a surface of the fixing plate 5 opposite to the lower plate 12, and the fixing plate 5 can be turned over relative to the upper plate 11 to move the second attachment/detachment mechanism 2 to the attachment/detachment position or the retracted position. As shown in fig. 6, the fixing plate 5 is turned over to the upper plate 11, the second detaching mechanism 2 is located at the detaching position, the second detaching mechanism 2 is located above the fixing plate 5, and the second detaching mechanism 2 can detach the battery pack having the second locking mechanism; as shown in fig. 7, the fixing plate 5 is turned over to be parallel to the upper plate 11, the second mounting and dismounting mechanism 2 is located at the avoiding position, the second mounting and dismounting mechanism 2 is located below the fixing plate 5, and the second mounting and dismounting mechanism 2 does not affect the action of the first mounting and dismounting mechanism 1 for mounting and dismounting the battery pack.
As shown in fig. 8, the second attachment/detachment mechanism 2 includes a rotating portion 21 and a rotation control mechanism 22, the second locking mechanism is provided with a locking end engaged with the rotating portion 21, and the rotating portion 21 is configured to rotate the locking end of the second locking mechanism for attachment/detachment; the rotation control mechanism 22 is used for controlling the rotation of the rotating portion 21, so that the rotating portion 21 can rotate the locking end to enable the second locking mechanism to be assembled and disassembled.
The rotation control mechanism 22 includes a motor 221 and a speed reducer 222, and an output of the motor 221 may be directly or indirectly input to the speed reducer 222. For example, a connection shaft (not shown) provided to the motor 221 can be inserted into a coupling (not shown) in the reducer 222, so as to connect the motor 221 and the reducer 222. The rotation speed of the motor 221 is changed by the speed reducer 222, and then the rotation part 21 is directly or indirectly driven by the speed reducer 222, so that the locking end of the second locking mechanism is screwed or unscrewed, and the second battery pack is detached or mounted. A bolt is a typical example of the locking end of the second locking mechanism. However, it is understood that the rotary portion 21 may be used to screw any member requiring a rotating operation, other than the bolt; it is only necessary that the rotary part 21 is designed to fit the shape of the locking end of the second locking mechanism.
Wherein, the upper plate 11 is provided with a hidden groove, and the mandril 14 can rotate into the hidden groove; when the ejector rod 14 is positioned in the hidden groove, the ejector rod 14 does not influence the action of the second disassembling and assembling mechanism 2 for disassembling and assembling the battery pack.
Wherein, first location fork 13 also can install on upper plate 11 foldingly, when first location fork 13 folded to the horizontality by vertical state, action of second dismouting mechanism 2 dismouting battery package is not influenced to first location fork 13.

The selection of the hiding manner of the first positioning fork 13, the second positioning fork 15 and the mandril 14 depends on the actual requirement of the dismounting space required by the second dismounting mechanism 2. When the multifunctional battery replacement equipment is used, other disassembly and assembly mechanisms are arranged besides the second disassembly and assembly mechanism 2, the first positioning fork 13, the second positioning fork 15 and the ejector rod 14 can be hidden in other modes, and the purpose of not influencing the actions of other disassembly and assembly mechanisms for disassembling and assembling the battery pack is achieved.
