And at the lower end of the supporting insertion rod 71, a downward pressing cooperating plate 72 is fixedly provided. The downward pressing cooperating plate 72 is located at the lower end of the cooperating moving plate 6. And when the downward pressing cooperating plate 72 moves downward, it is in contact with the contact cooperating plate 44.

[0041] A T-shaped connecting slideway 73 is opened on the bearing moving strip 7. And at one end of the bearing moving strip 7, a bearing mounting plate 74 is fixedly provided. On the bearing mounting plate 74, a second electric telescopic rod 75 is fixedly installed. The second electric telescopic rod 75 is fixedly installed with a driving cooperating strip 76. When initially performing battery swapping, a fully charged battery 3 is placed on the charging bearing platform 54 below the bearing mounting plate 74. In addition, both the first electric telescopic rod 12 and the second electric telescopic rod 75 work under the control of a controller in the prior art.

[0042] Two lower insertion driving blocks 77 are fixedly arranged at the lower end of the driving cooperation bar 76, and a connecting T-shaped bar 78 is fixedly arranged at one end of the driving cooperation bar 76 close to the second electric telescopic rod 75. The connecting T-shaped bar 78 is inserted into the T-shaped connecting slideway 73.

[0043] A movable strip plate 8 is installed on the power exchange substrate 5. The movable strip plate 8 is inserted into the bearing sleeve plate 59. Support insertion holes 81 are symmetrically formed on the movable strip plate 8. An inner bearing rod 591 is inserted into the support insertion holes 81. A third spring 811 is sleeved on the inner bearing rod 591.

[0046] When the robot needs to replace the battery, it moves to the battery replacement substrate 5, and the guiding and bearing rod 53 is inserted into the guiding connecting hole 28 to achieve the quick docking of the robot body 1 and the battery replacement substrate 5. Then, the first electric telescopic rod 12 drives the moving carrier 2 to move, so that the moving carrier 2 drives the battery 3 inside the robot out of the robot body 1. At the same time, as the moving carrier 2 moves, it will contact the cooperating moving plate 6. At this time, the contact cooperating plate 44 is below the pressing cooperating plate 72. In this way, under the action of the moving carrier 2, the cooperating moving plate 6 will be pushed towards the bearing vertical plate 51. As the cooperating moving plate 6 moves, under the action of the cooperating connecting hinge rod 70, the bearing moving bar 7 will be pushed downwards. Under the action of the pressing cooperating plate 72, the contact cooperating plate 44 will be pushed downwards, thereby driving the movable limiting plate 4 downwards, so that it no longer limits the battery 3, and at the same time, the fixed connecting rod 46 also withdraws from the fixed insertion hole 31, facilitating the movement of the battery 3. As the bearing moving bar 7 moves downwards, the bearing mounting plate 74 will push the connecting cooperating bar 84 below it downwards. Then, under the action of the driving cooperating hinge rod 83, the movable strip plate 8 will move away from the battery replacement substrate 5. In addition, as the bearing moving bar 7 moves downwards, the two downward insertion driving blocks 77 are respectively inserted into the cooperating driving grooves 32 on the battery 3 on the moving carrier 2 and the cooperating driving grooves 32 on the battery 3 on the charging bearing platform 54, and the downward insertion driving block 77 is in contact with the inner wall of the cooperating driving groove 32. Then, the second electric telescopic rod 75 extends to drive the driving cooperating bar 76 to move, thereby driving the two batteries 3 to move. The battery 3 moves under the support of the conveying extension plate 55, so that the discharged battery 3 moves to the charging bearing platform 54, and the fully charged battery 3 moves to the moving carrier 2 to complete the battery replacement. After the battery replacement is completed, the first electric telescopic rod 12 drives the moving carrier 2 to move in the reverse direction. At the same time, under the action of the second spring 63, the cooperating moving plate 6 follows it to move, so that the bearing moving bar 7 is reset, and at the same time, the movable limiting plate 4 is also reset to limit the battery 3, ensuring its stability during movement. In this way, the fully charged battery 3 is inserted into the power transmission channel 11. As the bearing moving bar 7 is reset, the movable strip plate 8 is also reset. In this way, the conductive sleeve 87 on one side of the battery replacement substrate 5 will be connected to the positive and negative electrodes of the battery 3 to be charged for charging. When the next battery replacement is carried out, since the second electric telescopic rod 75 is in the extended state, during the battery replacement, the second electric telescopic rod 75 retracts to complete the battery replacement. The battery replacement process repeats continuously to achieve convenient and fast battery replacement, which is very convenient.
