[0003] The purpose of the present invention is to provide a new energy battery swap station for rapid battery swapping, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, a technical solution adopted by the present invention is: a new energy battery swap station for rapid battery swapping, comprising a centering mechanism, a first battery swapping mechanism, a buffer mechanism, a second battery swapping mechanism and a battery compartment;

[0005] The centering mechanism is used to align and center the vehicle head;

[0006] The battery replacement mechanism is used to take the battery between the vehicle and the cache mechanism;

[0007] The second battery replacement mechanism is used to remove and place batteries between the cache mechanism and the battery compartment;

[0008] The cache mechanism includes a cache placement plate, on which two battery placement fixtures are provided. The two battery placement fixtures are respectively used to cache the fully charged batteries in the battery compartment and the low-charged batteries removed from the vehicle.

[0010] Preferably, the second battery replacement mechanism includes a second overhead rail arranged between the battery compartment and the cache mechanism, the second overhead rail is provided with a sliding frame that slides along the overhead rail, the sliding frame is provided with a sling assembly two and a locking and unlocking mechanism two connected to the lifting end of the sling assembly two, the sling assembly slides on the sliding frame and its sliding direction is perpendicular to the setting direction of the second overhead rail in the horizontal direction, the second locking and unlocking mechanism includes a main frame body two and a plurality of swing locks two that can swing in the horizontal direction.

[0011] Preferably, the cache mechanism further comprises a base, a support frame, a rotating ring and a driving assembly, wherein the support frame and the rotating ring constitute a thrust bearing structure, the support frame is fixed to the top surface of the base, the bottom surface of the rotating ring is higher than the bottom surface of the support frame, and the top surface of the rotating ring is higher than the top surface of the support frame, and the cache placement plate is fixed to the top surface of the rotating ring;

[0012] The driving assembly is used to drive the rotating ring to rotate on the supporting frame.

[0013] The battery placement tool is centrally symmetrically arranged on the cache placement plate with the rotating ring axis as the center.

[0014] Preferably, the cache placement plate is placed on an AGV trolley, and the AGV trolley moves along the length direction of the battery compartment.

[0015] Preferably, a plurality of in-place sensors are provided on the main frame 1 and the main frame 2. When all the in-place sensors respond, the swing lock 1 or the swing lock 2 opens and locks the battery.

[0016] Preferably, the main frame one and the main frame two are both provided with a number of movable pins that can move in the vertical direction. The movable pins are always subjected to a downward force. There is a resistance part on the battery slot frame for resisting the bottom end of the movable pin and causing it to rise. When the locking and unlocking mechanism two is in place, the in-place sensor can detect the rising movable pin.

[0017] Preferably, the sling assembly 1 and the sling assembly 2 are both provided with a connecting lock tube with an opening facing downward and a flared lower end, and the locking and unlocking mechanism 1 and the locking and unlocking mechanism 2 are both provided with a pin that can be inserted into the connecting lock tube, and the connecting lock tubes and pins in the battery replacement mechanism 1 and the battery replacement mechanism 2 are both provided with at least two groups.

[0018] The beneficial effects of the present invention are as follows: the present invention provides two battery placement fixtures on the buffer placement plate, and the two are used to temporarily store the fully charged batteries in the battery compartment and the low-charged batteries taken from the vehicle. In this way, before the vehicle is replaced with a battery, the second battery replacement mechanism can first move a fully charged battery to the buffer placement plate. In this way, after the battery replacement mechanism places the low-charged battery on the vehicle on the buffer placement plate, it can complete the removal of the fully charged battery by a short distance displacement (battery placement fixture-battery placement fixture). At the same time, after the battery replacement mechanism takes away the fully charged battery, the second battery replacement mechanism can take away the low-charged battery and take out the next fully charged battery and place it on the battery placement fixture. This process shortens the distance for battery replacement and effectively saves battery replacement time.

[0019] The second battery replacement mechanism is provided with a sliding rack, so that the batteries in the battery compartment can be placed side by side, making effective use of the space in the battery compartment.

[0020] Among them, by providing a support frame and a rotating ring, the cache placement plate can be rotated in the horizontal direction. At the same time, since the battery placement tool is symmetrically arranged on the center of the cache placement plate, after the battery replacement mechanism puts down the low-charged battery, it only needs to rise above the battery height and wait until the fully charged battery turns around before it can be taken out. It should be noted that in the rope-chain type sling assembly 1, due to the influence of inertia during the horizontal movement, it is necessary to wait for the sling assembly 1 to stabilize before it can be lowered to ensure accuracy. The setting of this solution greatly saves time in this part;

[0021] Among them, by setting up an AGV car, the spatial conflict between the overhead track 1 and the overhead track 2 can be avoided;

[0022] Among them, when the lifting device drives the locking and unlocking mechanism 2 to rise, the pin can be inserted into the connecting lock tube to keep the locking and unlocking mechanism 2 stable. This can ensure the rapid stability of the locking and unlocking mechanism 2. When it reaches the position for replacing the battery, it offsets the shaking of the locking and unlocking mechanism 2 caused by inertia during the horizontal movement of the lifting device, thereby improving the positioning accuracy of the battery.

[0040] Specifically, the following structure can be adopted: gear teeth are arranged around the side wall of the rotating ring 20 away from the support frame 19 so that the rotating ring 20 forms a gear shape, and the driving component 1 includes a motor 15 fixed to the frame and a driving gear 16 located at the output end of the motor 15, and the driving gear 16 is meshed with the gear teeth on the rotating ring 20;

In this way, before the vehicle is replaced with a battery, the battery replacement mechanism 2 4 can first transport a fully charged battery to the cache placement plate 17. In this way, after the battery replacement mechanism 1 places the low-charged battery on the vehicle on the cache placement plate 17, it can complete the removal of the fully charged battery through a short distance displacement (battery placement tool 18-battery placement tool 18). At the same time, after the battery replacement mechanism 1 2 takes away the fully charged battery, the battery replacement mechanism 2 4 can take away the low-charged battery and take out the next fully charged battery and place it on the battery placement tool 18. This process shortens the distance for battery replacement and effectively saves battery replacement time.
