1. A battery replacing device is used for replacing a battery pack on an electric automobile and is characterized by comprising a movable first frame and a sensor;

the sensor is arranged on the first frame and used for detecting whether a battery pack of the electric automobile is in a locked state or not.

2. The battery replacement device according to claim 1, wherein a locking mechanism is arranged on the electric vehicle, and the battery pack is locked by the locking mechanism; the sensor is a visual sensor, and the visual sensor is used for detecting whether the locking mechanism is in a locking state or not.

3. The battery swapping device of claim 2, wherein the locking mechanism comprises a lock base and a lock link, the lock base switching between a locked state and an unlocked state when the lock link moves relative to the lock base; the detection range of the visual sensor covers the lock connecting rod and the lock base, and the visual sensor is used for detecting whether the lock connecting rod is located at a locking position or not.

4. The battery replacement device as claimed in claim 2, wherein the vision sensor comprises a detection unit and a control unit, the detection unit is used for acquiring actual information of the locking mechanism, the control unit is used for storing standard information when the locking mechanism is locked, and the control unit is further used for comparing the actual information with the standard information; the control unit is further used for judging that the locking mechanism is in a locking state when the actual information is consistent with the standard information.

5. The battery swapping device of claim 4, wherein the locking mechanism comprises a lock base and a lock link, the lock base being switchable between a locked state and an unlocked state when the lock link moves relative to the lock base; the actual information of the locking mechanism acquired by the detection unit is the actual distance between the lock connecting rod and the lock base, and the standard information of the locking mechanism during locking is the distance between the lock connecting rod and the lock base during locking.

6. The battery swapping device of claim 2, wherein the coordinates of the locking mechanism when the first frame is in the battery swapping position are standard coordinates of the locking mechanism, the sensor is further configured to detect actual coordinates of the locking mechanism, the sensor is further configured to compare the actual coordinates of the locking mechanism with the standard coordinates to generate a coordinate difference, and the first frame moves according to the coordinate difference.

7. The battery swapping device of claim 2, further comprising an unlocking mechanism; the unlocking mechanism is arranged on the first frame and used for unlocking a battery pack of the electric automobile.

8. The battery swapping device of claim 7, wherein the unlocking mechanism comprises an unlocking lever configured to mate with an unlocking point of the locking mechanism.

9. The battery swapping device as claimed in claim 8, wherein the detection range of the sensor covers an unlocking point of the locking mechanism, and the sensor is used for detecting whether an unlocking rod of the unlocking mechanism is in contact with the unlocking point.

10. The battery swapping device of claim 8, wherein the unlocking mechanism comprises a drive mechanism that moves the unlocking lever to an unlocked position; when the unlocking rod is located at the unlocking position, the unlocking rod is in contact with an unlocking point of the locking mechanism.

11. The battery swapping device of claim 8, wherein the unlocking mechanism comprises a drive mechanism that moves the unlocking lever to a locked position; when the lock release lever is located at the lock position, the lock release lever does not hinder the action of the lock mechanism.

12. The battery replacement device as claimed in claim 1, wherein the first frame is further provided with a first guide fork, and the first guide fork is used for being matched with a positioning seat of an electric vehicle.

13. The battery swapping device of claim 1, further comprising a second frame disposed above the first frame, the second frame being configured to carry the battery pack.

14. The battery replacing device as claimed in claim 13, wherein the second frame is further provided with a second guide fork, and the second guide fork is used for being matched with a positioning block of a battery pack.

15. The battery swapping device of claim 1, further comprising a transmission head, wherein the transmission head is located on the first frame, and the transmission head is used for signal transmission between the battery swapping device and an electric vehicle.

16. The battery swapping device of claim 1, further comprising a slide rail, wherein the first frame is mounted on the slide rail and is capable of moving along the slide rail.

17. The battery swapping device of claim 16, further comprising a second frame disposed above the first frame, the second frame being mounted on the slide and movable along the slide.
