[0035] The charging device 100 of the inspection robot 200 proposed in the technical solution divides the battery cavity into a docking cavity 12 and a receiving cavity 13 by setting a substrate 11 in the battery compartment 10. When the battery unit 20 of the inspection robot 200 is inserted into the docking cavity 12, the side wall of the docking cavity 12 and the substrate 11 provide support for the battery unit 20; the card block 143 in the receiving cavity 13 passes through the avoidance groove 111 and docks with the card slot 22 to ensure that the position of the battery unit 20 is fixed during the charging process, and the battery unit 20 is firmly connected to the charging device 100 and is not easy to fall off; the terminal seat 142 in the receiving cavity 13 passes through the avoidance groove 111 and docks with the power terminal 21 and conducts to charge the battery unit 20, and the wear between the terminal seat 142 and the power terminal 21 is small, which effectively improves the durability of the terminal seat 142 and the power terminal 21 and extends the service life. In addition, the battery unit 20 of the inspection robot 200 does not need to be connected to a cable, has few restrictions on use, and is more flexible in setting.

[0036] In one embodiment, the docking cavity 12 and the accommodating cavity 13 are vertically spaced apart, the docking cavity 12 forms a docking port for the battery unit 20 to be inserted in the longitudinal direction, and the avoidance groove 111 extends in the longitudinal direction.

When the battery unit 20 is inserted into the docking cavity 12, the driving mechanism drives the placement plate 141 to move up to drive the terminal seat 142 and the card block 143 set on the placement plate 141 to move up. The terminal seat 142 and the card block 143 pass through the avoidance groove 111 and extend into the docking cavity 12, so that the terminal seat 142 and the card block 143 are docked with the power terminal 21 and the card slot 22 respectively; when the inspection robot 200 is fully charged, the driving mechanism drives the placement plate 141 to descend and drives the terminal seat 142 and the card block 143 to descend, so that the terminal seat 142 and the card block 143 are separated from the power terminal 21 and the card slot 22 respectively, so that the battery unit 20 can be separated from the docking cavity 12. By providing a driving mechanism to drive the placement plate 141 to rise and fall, it is convenient to control the elevation height of the placement plate 141 , so that the terminal seat 142 can be docked with the battery cells 20 of different heights, thereby improving the applicability of the charging device 100 .

[0040] In one embodiment, a through hole 1531 is provided on the side wall of the sleeve 153, and a vertically extending first tooth segment 1521 is provided on one side of the rod wall of the telescopic rod 152 corresponding to the through hole 1531. The driving structure 151 includes a driving component 154 and a first gear 155. The first gear 155 is provided outside the sleeve 153 and meshes with the first tooth segment 1521 at the through hole 1531.

[0041] Furthermore, the driving assembly 154 drives the first gear 155 to rotate, so that the first gear 155 drives the telescopic rod 152 to move up and down relative to the sleeve 153, so as to realize the lifting and lowering of the placement plate 141. By providing a through hole 1531 on the sleeve 153, while the sleeve 153 is maintained to provide support and guidance for the lifting direction of the telescopic rod 152, it is convenient for the first gear 155 outside the sleeve 153 to mesh with the first toothed section 1521 on the telescopic rod 152, the structure is simple, and the first gear 155 is easy to debug and repair.

[0042] In one embodiment, the driving assembly 154 includes a transmission rod 1541, a second gear 1542, a driving rod 1543, a sliding plate 1544 and a driving member 1545.
