Description

Technical Field

[0001] This utility model relates to a battery rack buffer mechanism for a battery swapping station, belonging to the technical field of buffer mechanisms. Background Technology

[0002] With the increasing popularity of electric vehicles, how to provide timely and effective power replenishment for electric vehicles with insufficient battery power has become a major concern for both manufacturers and car owners. Currently, charging and battery swapping stations adopt a power battery replacement model, directly replacing the depleted battery pack with a fully charged one, completing the power replenishment within minutes. Therefore, it is a highly efficient way to replenish power.

[0003] Chinese Patent Publication No. (CN 220333744 U) discloses a staggered conveying buffer battery rack. The buffer battery rack has a staggered conveying mechanism at its bottom, which includes parallel guide rails and several sets of scissor arm brackets slidably mounted on the guide rails. Each set of scissor arm brackets has an upper support frame fixedly connected to its top for supporting the battery packs and a lower support frame fixedly connected to its bottom. Several movable blocks that cooperate with the guide rails are fixedly installed at the bottom of the lower support frame, and a first power component is connected to the movable blocks. Multiple battery packs are placed on the upper support frame corresponding to each set of scissor arm brackets. Each battery pack storage station on the buffer battery rack has a battery pack gripper fixedly installed on its frame for clamping and fixing the battery packs. This invention solves the problems of existing buffer battery storage racks, such as large space occupation, insufficient utilization of the storage space, long stroke, low transmission efficiency, long interaction time between low and full charge, and increased cycle time of the entire station.

[0004] However, the existing motor frame only has a battery buffer structure, which cannot quickly lift the battery, improve the RGV battery discharge operation, and reduce the battery swapping cycle.

[0005] To address this, a battery rack buffer mechanism for battery swapping stations is proposed. Utility Model Content

[0006] In view of this, the present invention provides a battery rack buffer mechanism for a battery swapping station to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0007] The technical solution of this utility model is implemented as follows: A battery rack buffer mechanism for a battery swapping station includes a placement rack. A buffer lifting mechanism is provided on the inner side of the placement rack. The buffer lifting mechanism includes a dual-head motor, a rotating rod, a connecting rod, and a fixed wheel. The top of the dual-head motor is fixedly connected to the top of the placement rack. The inner side of the rotating rod is fixedly connected to the output end of the dual-head motor. The outer side of the connecting rod is fixedly connected to the inner side of the rotating rod. The inner side of the fixed wheel is fixedly connected to the outer side of the connecting rod. The outer side of the fixed wheel is movably connected to the inner side of the placement rack.

[0008] More preferably, the inner side of the placement rack is fixedly connected with an upper buffer and a lower buffer.

[0009] More preferably, a rotating wheel is fixedly connected to the inner side of the placement rack, and a chain is sleeved on the surface of the rotating wheel, with the other side of the chain sleeved on the surface of the fixed wheel.

[0010] More preferably, a sensor is fixedly connected to the front side of the dual-head motor, and the sensor accurately identifies the position and height.

[0011] The present invention has the following advantages due to the adoption of the above technical solution:

[0012] I. This utility model uses a buffer lifting mechanism, which mainly includes a battery buffer lift and a battery buffer. The battery buffer lift is designed to improve the battery turnover rate. The RGV places the depleted battery on the upper buffer, and after the buffer is lifted, the dual-head motor places the fully charged battery on the lower buffer. The buffer lift descends to place the fully charged battery on the RGV. This structure saves the RGV's upward stroke. With the cooperation of the mechanism, the battery swapping cycle is accelerated, the battery lifting function is increased, the RGV's battery discharging action is reduced, and the battery swapping cycle is accelerated.

[0013] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.
