All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The battery swapping device of the present invention is described below with reference to fig. 2 to 4.
As shown in fig. 2 to 4, the battery replacing device provided in the embodiment of the present invention includes a manipulator, a grabbing mechanism, a side link 1, a connecting rod 2 and a telescopic assembly 3.
The grabbing mechanism is arranged at the execution end of the manipulator and is rotationally connected with the execution end of the manipulator, and the grabbing mechanism is arranged along the horizontal direction relative to the rotation axis of the execution end of the manipulator. The manipulator orders about the in-process that snatchs mechanism and battery package 4 remove, and the terminal arm festival of manipulator inclination can change unavoidably, through making snatch the mechanism and rotate for the terminal arm festival of manipulator, can make battery package 4 keep horizontal gesture on snatching the mechanism to ensure that battery package 4 can be smoothly with insert electric interface grafting or break away from the grafting.
The side link 1 and the connecting rod 2 are hinged with each other, the side link 1 and the connecting rod 2 are hinged with the tail end arm section of the manipulator and the grabbing mechanism respectively, the hinged shafts are parallel to each other and are parallel to the rotating axis of the grabbing mechanism relative to the manipulator, so that the side link 1, the connecting rod 2, the grabbing mechanism and the manipulator form a connecting rod mechanism taking the tail end arm section of the manipulator as a frame.
The telescopic assembly 3 is arranged between the side link 1 and the tail end arm section of the manipulator and is used for driving the side link 1 to rotate relative to the tail end arm section of the manipulator. Through the rotation of driving side link 1 for the terminal arm section of manipulator, can drive and snatch the mechanism and rotate for the terminal arm section of manipulator.
In the present embodiment, the side link 1 is used as a driven member, and as shown in fig. 2, the component force of the acting force F of the telescopic assembly 3 on the side link 1 in the direction perpendicular to the side link 1 is the main driving force for driving the side link 1 to rotate, and is herein referred to as a first acting force F1.
Accordingly, in the prior art, the linear driving mechanism 14 is directly connected to the grabbing structure 13, and the grabbing structure 13 is used as a driven member, as shown in fig. 1, the component force of the acting force F' of the linear driving mechanism 14 on the grabbing structure 13 in the direction perpendicular to the grabbing structure 13 is the main driving force for driving the grabbing structure 13 to rotate, and is referred to as a second acting force F2.
In the case where the force F generated by the telescopic assembly 3 is the same as the force F' of the linear drive mechanism 14 on the gripping structure 13, the first force F1 is greater than the second force F2. When the grabbing mechanism and the grabbed battery pack 4 are completely the same, the acting force generated by the telescopic assembly 3 is required to be smaller than the acting force generated by the linear driving mechanism 14 in the prior art, so that the requirements on the telescopic assembly 3 can be reduced, and the cost is reduced. The problem of adopt the arm to trade the power trade power station that the electricity traded among the prior art to have high requirements for linear drive mechanism is solved.
In an embodiment of the present invention, the telescopic assembly 3 may be a rigid support or a tension line with adjustable length. The tension wire is a flexible part and needs to be arranged on one side of the adjacent components which is subjected to tension. The tension line can be a steel wire rope, and the length of the tension line can be adjusted by a winch.
The side link 1 and the connecting rod 2 can be arranged at the upper end of the grabbing mechanism and can also be arranged at the side surface of the grabbing mechanism. When the side link 1 and the connecting rod 2 are arranged at the upper end of the grabbing mechanism, the telescopic assembly 3 can be a rigid supporting piece or a tension wire. When the side links 1 and the connecting rods 2 are arranged on the side of the grabbing mechanism, the telescopic assembly 3 can only be selected as a rigid support.
And for the rigid support piece, two ends of the rigid support piece are respectively connected with the tail end arm section of the manipulator and the grabbing mechanism. And for the tension wire, the winch is fixed on the tail end arm section of the manipulator, the steel wire rope is wound on the winding drum of the winch, and the end part of the steel wire rope is connected with the upper end of the grabbing mechanism.

The robot is configured such that the execution end can move in both the horizontal direction and the vertical direction, and the above-mentioned top gripping mechanism 5 and side gripping mechanism 6 are selectively connected to the execution end of the robot.
For a battery pack 4 that needs to be gripped from the top, a top gripping mechanism 5 is connected to the execution end of the manipulator, see fig. 3. The manipulator is controlled to move the top grabbing mechanism 5 to the position above the battery pack 4 in an empty state on the vehicle to be replaced or to the position above the battery pack 4 in a full state on the charging bin, and then the manipulator is controlled to drive the top grabbing mechanism 5 to move downwards, so that the battery pack 4 can be grabbed from the top of the battery pack 4. After the action of grabbing the battery pack 4 is completed, the manipulator is controlled to drive the top grabbing mechanism 5 to move upwards, and after the battery pack 4 is disconnected with the plug-in interface, the manipulator is controlled to drive the top grabbing mechanism 5 to switch positions between the vehicle to be changed and the charging bin. The action process of the manipulator controlling the top gripping mechanism 5 when the battery pack 4 is plugged into the plug-in interface is opposite to the action process of the manipulator controlling the top gripping mechanism 5 when the battery pack 4 is not plugged into the plug-in interface.
For the battery pack 4 that needs to be gripped from the side, a side gripping mechanism 6 is connected to the execution end of the manipulator, see fig. 4.

After the action of grabbing the battery pack 4 is completed, the manipulator is controlled to drive the side grabbing mechanism 6 to be far away from the battery pack 4 along the horizontal direction, and after the battery pack 4 is disconnected with the plug-in interface, the manipulator is controlled to drive the side grabbing mechanism 6 to switch the position between the vehicle to be replaced and the charging bin. The action process of the manipulator control side grabbing mechanism 6 when the battery pack 4 is plugged into the plug-in interface is opposite to the action process of the manipulator control side grabbing mechanism 6 when the battery pack 4 is not plugged into the plug-in interface.
In summary, different grabbing mechanisms are switched at the execution end of the manipulator, and the battery packs 4 with different structures can be grabbed.
When the demand for the top-gripping type power exchanging station is increased and the demand for the opposite-side gripping type power exchanging station is reduced, the side-gripping mechanism 6 on the manipulator of the side-gripping type power exchanging station can be replaced by the top-gripping mechanism 5, a new top-gripping type power exchanging station does not need to be additionally established, and the side-gripping type power exchanging station is prevented from being idle. When the demand of the opposite-side grab type power exchanging station is increased and the demand of the opposite-side grab type power exchanging station is reduced, the top grab mechanism 5 on the manipulator of the top grab type power exchanging station can be replaced by the side grab mechanism 6, a new side grab type power exchanging station does not need to be additionally established, and the situation that the top grab type power exchanging station is idle is avoided. Therefore, the management is convenient, and the cost is reduced.
It should be noted that, for the switching between the top gripping mechanism 5 and the side gripping mechanism 6 on the manipulator, an automatic replacing mechanism may be provided for replacement, or manual replacement may be performed.
