In this step, the first clamping pieces 1 of the positioning and unlocking devices 10 respectively clamp the corresponding lock bases 201, so that multipoint simultaneous positioning is realized, the unlocking safety is improved, and the unlocking success rate is also improved.
Before the first card member 1 is clamped on the lock base 201, an adjusting link can be provided to realize positioning, and the first card member 1 can detect the specific position of the lock base 201 through the first position detection device and detect whether the lock base is clamped in place through the first position detection device. The first position detection device is used for detecting the specific position of the lock base 201 and transmitting the acquired position to the battery replacing equipment, and the position of the first clamping piece 1 is adjusted through the battery replacing platform 20 of the battery replacing equipment, so that the positioning groove 111 of the first clamping piece 1 can be aligned to the lock base 201, and accurate clamping and positioning are realized. Meanwhile, when the positioning and unlocking device 10 is clamped in place, the first position detection device can detect the specific position of the lock base 201 to the battery replacing device, judge whether the lock base 201 is clamped in place or not through the position between the first clamping piece 1 and the lock base 201, and stop adjusting the position of the first clamping piece 1 when the battery replacing device is clamped in place.
In this step, after the locking is in place, a locking signal sent by the first position detection device is sent to the battery replacement device, the battery replacement device will control the ejection mechanism 2 after receiving the locking signal, an ejection rod of the ejection mechanism 2 will be inserted into the locking groove 204 to eject the locking tongue 203, and when the positioning unlocking device 10 is ejected in place, the locking tongue 203 does not block the locking shaft 202 any more, and the locking shaft 202 can be separated from the locking groove 204.
In this embodiment, the lock shaft 202 will abut against the notch of the lock tongue 203 in the lock slot 204, and after the lock shaft is locked in place, the lock signal sent by the first position detecting device is sent to the battery replacement device, and the platform plate 21 moves along the advancing direction of the battery pack, so that the battery pack moves forward, that is, the lock shaft 202 will move rightward in fig. 4, so that a gap is formed between the lock shaft 202 and the lock tongue 203, and the subsequent lock tongue 203 is conveniently jacked up.
When the ejection mechanism 2 is ejected in place, the lock shaft 202 can be ensured to be separated from the locking groove 204, and when the ejection mechanism 2 is not ejected in place, the locking mechanism 200 is damaged or cannot be unlocked. In order to determine whether the ejection mechanism 2 is ejected in place, the battery replacement device can detect the specific position of the lock tongue 203 through the second position detection device and detect whether the lock tongue is jacked in place through the second position detection device, and the second position detection device sends a jacking in-place signal. The specific position of the bolt 203 is detected by the second position detection device, whether the bolt 203 blocks the lock shaft 202 and whether the bolt 203 is jacked in transition is judged, after jacking is in place, the detected jacking in-place signal is sent to the battery replacing equipment by the second position detection device, the battery replacing equipment receives the jacking in-place signal and judges that the bolt 203 jacks in place, and the safety and stability of the positioning and unlocking device 10 are greatly improved. And after the battery pack is ejected to the right position, the second position detection device sends an ejection to-the-right position signal to the battery replacement equipment, and the battery pack is unlocked through the battery replacement equipment.
Whether the ejection mechanism 2 is ejected in place or not can be judged without a second position detection device, a first limiting mechanism can be arranged on the first clamping piece 1 and used for abutting against an ejection rod of the ejection mechanism 2 so as to limit the upward transition and extension of the ejection rod, and the first limiting mechanism sends an ejection in-place signal. The first limiting mechanism has a limiting effect, and the first limiting mechanism can prevent the ejector rod of the ejection mechanism 2 from moving upwards, so that the ejector rod of the ejection mechanism 2 cannot be extended in a transition way, and the lock tongue 203 is prevented from being jacked in a transition way; meanwhile, the ejector rod of the ejector mechanism 2 abuts against the first limiting mechanism, and at this time, the lock tongue 203 no longer blocks the lock shaft 202 from being separated from the lock groove 204. After the battery pack is ejected to the right position, the first limiting mechanism sends an ejection to-the-right position signal to the battery replacing equipment, and the battery pack is unlocked through the battery replacing equipment.
After the locking shaft is ejected to the right position, the battery replacing device drives the battery replacing platform 20 to move when receiving the ejection to the right position signal, so that the locking shaft 202 moves backwards. The battery replacing platform 20 moves along the backward direction of the battery pack, so that the battery pack moves backward, and meanwhile, the lock shaft 202 is driven to move backward, and the lock shaft 202 is separated from the locking groove 204.
In this embodiment, the ejector rod of the ejector mechanism 2 is inserted into the locking groove 204 and ejects the locking tongue 203 upwards, and since the ejector rod of the ejector mechanism 2 is located in the locking groove 204, the lock shaft 202 cannot completely pass through the locking tongue 203 and pass through the vertical portion in the locking groove 204, the lock shaft 202 will move backwards and be separated from the blocking block of the locking tongue 203, so that the subsequent lock shaft 202 can be smoothly separated from the locking groove 204.
Whether the ejector mechanism 2 needs to be retracted requires a judgment as to whether the lock shaft 202 is out of the jamming blockage of the lock tongue 203. In order to determine whether the lock shaft 202 is separated from the blocking block of the lock tongue 203, the battery replacement device may detect a specific position of the lock shaft 202 moving backwards through a third position detection device and detect whether the lock shaft is moved in place through the third position detection device. The third position detection device is used for detecting the specific position of the lock shaft 202 to judge whether the lock shaft 202 is separated from the blocking block of the lock tongue 203, so that the accuracy of positioning the unlocking device 10 is ensured. The third position detection device sends a specific position signal of the lock shaft 202 to the battery replacing device, the battery replacing device receives the specific position signal and judges whether the lock shaft 202 moves backwards in place, and after the lock shaft 202 moves backwards in place, the battery pack is unlocked through the battery replacing device. The first position detection device, the second position detection device and the third position detection device can be position indicators, sensors and the like.
And a second limiting mechanism can be arranged on the battery replacing equipment and is used for abutting against and limiting the lock shaft 202 to move backwards in a transition manner without using a third position detection device when judging whether the lock shaft 202 moves backwards in place. The second limiting mechanism plays a limiting role, and the backward movement of the lock shaft 202 can be prevented through the second limiting mechanism, so that the lock shaft 202 cannot move backwards in a transition manner, and the damage to the lock tongue 203 is avoided; meanwhile, the second limiting mechanism can abut against the battery replacing platform 20, the battery pack or the lock shaft 202 to prevent the lock shaft 202 from moving backwards in a transition manner, and at this time, the lock tongue 203 is not blocked to prevent the lock shaft 202 from being separated from the lock groove 204. After the battery pack moves backwards in place, the second limiting mechanism is abutted to acting force and sends a signal to the battery replacing device, and the battery pack is unlocked through the battery replacing device.
And step 300, the battery replacement equipment controls the ejection mechanism 2 to retract.
In this step, the ejector rod of the ejector mechanism 2 will retract out of the lock groove 204, no longer blocking the lock shaft 202 from coming out of the lock groove 204, ensuring an unlocking operation.
When the positioning unlocking device 10 is retracted, the ejector rod of the ejector mechanism 2 no longer abuts against the latch bolt 203, so that the latch bolt 203 intentionally restores the original state under the action of the spring, the latch bolt 203 swings downwards, and the bottom of the latch bolt 203 abuts against the top of the lock shaft 202.
Step 400 is further included after step 300, and step 400 is that the battery replacement device drives the battery pack to continue to move until the lock shaft 202 is disengaged from the lock groove 204. After the ejector rod of the ejector mechanism 2 retracts, the battery replacing device drives the battery pack and the lock shaft 202 to continuously move backwards, so that the lock shaft 202 is completely separated from the clamping support of the lock tongue 203, and the unlocking operation is completed; after the unlocking is completed, the battery replacing device drives the battery pack and the lock shaft 202 to move downwards, and the battery pack is detached from the battery replacing support 100. Otherwise, the locking operation is realized.
