Description

Technical Field

[0001] The invention relates to a battery transport system with a synchronous belt and a battery swap station or an energy storage station. Background Art

[0002] As the battery charging time of electric vehicles is limited, quick-swap electric vehicles have been accepted by more and more users. It is only necessary to replace the depleted battery pack and install a fully charged battery pack in the battery swap station, saving a long battery charging time. The battery swap station is equipped with: battery swap equipment for battery removal or installation, battery transport equipment for transporting battery packs, and charging equipment for charging battery packs.

[0003] Existing battery transfer devices usually achieve lifting and movement through a guide mechanism, a transmission mechanism, and a drive mechanism, so as to transfer batteries between battery compartments. The Chinese patent application with publication number CN110901601A discloses an AGV charging station, which adopts the principle of multi-axis linkage and the design of a multi-axis system, specifically exchanges and charges batteries in the X-axis, Y-axis, Z-axis, and the direction of battery pulling and pushing, removes the batteries from the AGV trolley, and delivers the batteries into the load-bearing frame. The Chinese patent application with publication number CN111717062A discloses a battery exchange system for heavy trucks and its use method, in which the mechanical arm on the battery exchange stacker can move under the load of the lifting device and the transverse movement device to pick up and place the batteries.

[0004] However, the transfer device disclosed in the above-mentioned prior art has a complex structure, low flexibility, and is not easy to expand, which limits its scope of application; moreover, the entire lifting process lacks stability and is prone to tilting, jamming, collision, etc., resulting in damage to the equipment.

[0005] In the prior art, the car containing the battery is lifted and lowered by a driving wheel chain arranged in a guide device, which has high requirements on the guide structure and requires regular maintenance (oiling). Moreover, after long-term use, the wear of the driving wheel chain easily affects the positioning accuracy, resulting in inaccurate positioning between the car and the battery compartment. In addition, the driving wheel chain has a fixed structure and a narrow application range, which is not convenient for expansion design and height expansion.

[0006] In addition, the battery swap stations or energy storage stations or energy storage stations built in the traditional way are mostly integrated structures, which require the relevant materials to be transported to the site before construction. The battery swap station itself has a large space and the corresponding construction materials are also large in specifications. It is not only inconvenient for transportation and high in cost, but also has a long construction period and is not conducive to later expansion and upgrading of battery swap equipment.

[0007] The Chinese patent application with publication number CN106043247A discloses a modular and expandable battery swap station equipment and charging rack. The battery storage modules in the charging rack are stacked together in a building block manner, and the battery transfer device can travel through the battery storage modules. The Chinese patent application with publication number CN208181025U discloses a battery warehouse and a new energy vehicle battery swap station, wherein the battery warehouse has a plurality of battery racks arranged in series, and each battery rack is respectively provided with a corresponding elevator, or the battery racks share one elevator. However, they are all for splicing the charging warehouses in the battery racks. When constructing a battery swap station, the charging warehouses still need to be spliced ​​in sequence, and the battery swap station itself cannot be modularized. Summary of the invention
