Description

Technical Field

[0001] The utility model belongs to the technical field of new energy vehicles, and in particular relates to a cache mechanism of a battery pack of a new energy electric vehicle. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels but adopt new vehicle power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include: hybrid vehicles, pure electric vehicles, fuel cell vehicles, hydrogen engine vehicles, gas vehicles, alcohol ether vehicles, etc.

[0003] Currently, when battery packs are replaced at battery swap stations, the batteries are generally disassembled using equipment and then transported to the corresponding battery compartment for charging. However, during this period, the disassembly equipment is waiting until the battery is placed in the charging compartment before the next step can be performed, which greatly delays the charging time. Utility Model Content

[0004] In order to solve the above technical problems, a technical solution adopted by the utility model is as follows:

[0005] A cache mechanism for a new energy electric vehicle battery pack comprises a frame body, a lifting structure and a cache structure mounted on the frame body, wherein a first driving element for driving the lifting structure and a second driving element for driving the cache structure are also mounted on the frame body;

[0006] The lifting structure comprises at least four sets of slide rails installed on the frame body and a lifting part sliding on the slide rails, and the lifting part is also fixedly connected to a tensioning part, and the tensioning part is used to connect with the first driving element;

[0007] The cache structure includes at least two groups of gripping parts and at least two groups of cache parts. The two groups of gripping parts and the cache parts are respectively arranged on both sides of the frame body, and the gripping parts and the cache parts are respectively fixedly connected to the second driving element.

[0008] Furthermore, the lifting part is an L-shaped lifting block, the lifting block is fixedly connected to the anti-sliding block, and each two groups of lifting blocks are fixedly connected via a connecting plate.

[0009] Furthermore, the tensioning part includes a tensioning body, which is respectively provided with a fixed end and a tensioning end; the tensioning end includes an adjusting rod sliding in the tensioning body and two sets of inner fixing plates and outer fixing plates sleeved on the adjusting rod, the inner fixing plate is located inside the tensioning body, the outer fixing plate is located outside the tensioning body, an elastic element is provided between the inner fixing plate and the outer fixing plate, and a fastener is provided on the side of the adjusting rod away from the inner fixing plate.

[0010] Furthermore, the gripper portion includes a gripper and a second driving element for driving the gripper to move, the gripper is fixedly connected to a guide column, the frame body is provided with a guide groove for accommodating the guide column, and the guide column slides in the guide groove.

[0011] Furthermore, the first driving element includes a motor and a belt transmission assembly connected to the output end of the motor, and the belt transmission assembly is respectively connected to the tensioning parts.

[0012] Beneficial effects of the utility model:

[0013] The utility model utilizes a chain to drive the battery pack removed from the battery-swapping vehicle, which is first transported to the cache position through a lifting structure, and then the cache position motor gripper grabs the battery pack. The lifting structure then descends, and the cache position can wait for mechanical equipment to transport the battery pack to the charging bin. During this period, the lifting structure can return to its original position to store the next group of battery packs, thereby realizing rapid battery replacement operations for the vehicle and saving battery replacement time.
