Besides, the embodiment of the utility model provides a power battery changes device and maintains conveniently, only needs power battery to change the device promptly and rolls off from spacious position and can maintain.
On the basis of the above solution, optionally, referring to fig. 2, the power battery replacing device further includes: a drive mechanism 80; the driving mechanism 80 is located on the main body 20 and is respectively connected with the traveling mechanism 10, the locking mechanism 50 and the lifting mechanism 70; the driving mechanism 80 is used for providing power for the traveling mechanism 10, the locking mechanism 50, and the lifting mechanism 70.
The drive mechanism 80 may include, for example, a motor. Specifically, when the power battery replacing device needs to replace the power battery for the new energy vehicle, the control system 60 receives a control instruction sent by an external control device, and the control system 60 controls the driving mechanism 80 to start working according to the control instruction, so as to provide power for the traveling mechanism 10, the locking mechanism 50, and the lifting mechanism 70.

When the first sensor 90 is a contact switch sensor, in particular, the first sensor 90 is provided on the support mechanism 40, in contact with the power cells, illustratively, the number of first sensors 90 is four, and the four first sensors 90 are angularly distributed in pairs, namely, the four first sensors 90, which are diagonally distributed, are in contact with the four corners of the power battery, respectively, because the four corners of the power battery of the present embodiment are provided with bolts penetrating the power battery, respectively, the power battery is fixed in the vehicle body by the locking mechanism 50 being connected with the bolts, therefore, if one corner of the power battery is not fixed in the vehicle body, the signal received by one of the four first sensors 90 will be different from the signals received by the other three first sensors 90, and the four first sensors 90 will send the respective received signals to the control system 60, so that the control system 60 can determine that the power battery is not successfully locked according to the signals. For example, at this point the control system 60 may send an error signal to the external controller, thereby informing the operator that the power cell has not been successfully locked. Similarly, the power battery can be detached only by the locking mechanism 50, that is, the locking mechanism 50 is connected with the bolt, the bolt is loosened to separate the power battery from the vehicle body, if the remaining three corners are separated from the vehicle body while one corner of the power battery is still fixed in the vehicle body, the signal received by one of the four first sensors 90 will be different from the signals received by the other three first sensors 90, the four first sensors 90 will send the respective received signals to the control system 60, and the control system 60 can determine that the power battery is not successfully detached according to the signals.

Specifically, the locking mechanism 50 is connected to the control system 60, and when receiving a signal from the control system 60, the electric push rod 54 moves left and right to drive the rack 52 to move, and the gear 53 is engaged with the rack 52 to drive the gear 53 to rotate, and the locking and unlocking head 51 is fixed on one side of the gear 53 to drive the locking and unlocking head 51 to rotate. Illustratively, the power battery is fixed in the vehicle body by the lock-release head 51 being connected with a bolt penetrating the power battery.
Based on the above solution, optionally, with continuing reference to fig. 3, 4 and 5, the locking mechanism 50 further includes: a limit screw 55; the limit screw 55 is located on the locking mechanism 50 and is used for controlling the rotation angle of the lock detaching head 51.
Specifically, fig. 6 is a cross-sectional view of the lock detaching head provided in the first embodiment of the present invention, referring to fig. 6, the lock detaching head 51 further includes a limiting shaft 520, when the lock detaching head 51 rotates, because the length of the limiting shaft 520 is greater than the diameter of the rotating shaft 510 of the lock detaching head 51, when the limiting shaft 520 rotates, the limiting shaft 520 contacts with the limiting screw 52, because the limiting screw is fixed without external force, when the limiting shaft 520 rotates to contact with the limiting screw 52, the limiting shaft will not rotate, so that the rotating angle of the limiting shaft 520 can be limited by the limiting screw 52, and further the rotating angle of the lock detaching head 51 can be limited. If the rotation angle of the lock detaching head 51 is decreased, the limiting screw 55 can be manually rotated to make the depth of the limiting screw into the locking mechanism 50 be larger, and at this time, the limiting shaft 520 cannot be rotated by a too large angle due to the limitation of the limiting screw 55, that is, the rotation angle of the lock detaching head 51 is also decreased.
Based on the above solution, optionally, with continued reference to fig. 4 and 5, the locking mechanism 50 is fixed on the supporting mechanism through a fixing plate 56; a second sensor 57 and a third sensor 58 are sequentially arranged on the fixing plate 56 along the moving direction of the electric push rod 54; the locking mechanism 50 further includes a reflector sheet 59; the reflection sheet 59 is fixed on the electric push rod 54; the electric push rod 54 drives the reflector 59 to move; the reflection sheet 59 is used for reflecting the detection light beam emitted by the second sensor 57 when moving to the emission end of the second sensor 57 and reflecting the detection light beam emitted by the third sensor 58 when moving to the emission end of the third sensor 58; the second sensor 57 sends a first signal to the external controller when receiving the detection beam reflected by the reflection sheet 59, and the third sensor 58 sends a second signal to the external controller when receiving the detection beam reflected by the reflection sheet 59, so as to indicate that the external controller determines that the power battery is completely detached or installed according to the first signal and the second signal.
The second sensor 57 and the third sensor 58 may include, for example, a photosensor. Specifically, the second sensor 57 and the third sensor 58 are connected to the control system 60, and emit a detection beam when receiving a signal from the control system, and when the electric push rod 54 is at the home position, i.e., the detaching head 51 is in the home position, without rotating, the reflective sheet 59 blocks the detection beam emitted from the second sensor 57, i.e., the detection beam is reflected back to the second sensor 57 by the reflective sheet 59, at which time the second sensor 57 sends a signal to the external controller, when the electric push rod 54 is at the final position, i.e., the detaching head 51 has rotated to a preset angle, the reflective sheet 59 blocks the detection beam emitted from the third sensor 58, the detection light beam is reflected back to the third sensor 58 by the reflective sheet 59, and at this time, the third sensor 58 also sends a signal to the external controller, and the external controller judges that the power battery is locked or detached by the detaching head 51 according to the signals sent by the second sensor 57 and the third sensor 58. If one of the sensors does not receive the reflected detection light beam, that is, the lock-detaching head driven by the electric push rod 54 does not rotate to a preset angle, the external controller determines that the power battery is not locked or successfully detached through the detaching head 51 according to signals sent by the second sensor 57 and the third sensor 58.
On the basis of the above scheme, optionally, the power battery replacing device further includes a power supply module (not shown in the figure), and the power supply module is connected with the driving mechanism 80 and is used for charging the driving mechanism 80.
