technical field

The invention relates to a transmission mechanism of a battery transfer device, a battery transfer device, a battery transfer system and an exchange station or an energy storage station.

Background technique

With the limitation of the battery charging time of electric vehicles, quick-change electric vehicles have been accepted by more and more users. It is only necessary to replace the depleted battery in the battery swap station and install a fully charged battery to save energy. long battery charging time. The power exchange station is equipped with power exchange equipment for removing or installing the battery, a battery transfer device for transferring the battery, and a charging device for charging the battery.

In the existing battery transfer device, a guide mechanism, a transmission mechanism and a drive mechanism are usually used to achieve up-down movement, so as to perform battery transfer between battery bays. 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 multi-axis system, and specifically charges the battery in the direction of X axis, Y axis, Z axis and battery pulling and pushing. Carry out exchange charging, take out the battery from the AGV trolley and send the battery into the carrying frame.

However, the transport device disclosed in the above-mentioned prior art has a complex structure, low flexibility, and inconvenient expansion design, which limits its application scope; moreover, the entire lifting process has insufficient stability, and is prone to inclination, jamming, etc. Collision, etc., resulting in equipment damage.

In the prior art, the car accommodating the battery is also driven up and down by the sprocket chain structure, but this structure has high requirements on the guiding mechanism and requires regular maintenance (eg oiling). In addition, after long-term use, the positioning accuracy is easily affected by the wear of the sprocket chain, resulting in inaccurate positioning between the car and the battery bay. In addition, the fixed application range of the sprocket chain structure is narrow, which is inconvenient for the expansion design of the battery rack and the power exchange station.

Now new energy vehicles are more and more popular with consumers. The energy used by new energy vehicles is basically electric energy. New energy vehicles need to be charged after the electric energy is used up. Due to the limitations of current battery technology and charging technology, new energy vehicles are fully charged. It takes a long time, and it is not as simple and fast as refueling the car directly. Therefore, in order to reduce the user's waiting time, it is an effective means to replace the battery when the electric energy of the new energy vehicle is almost exhausted. In order to facilitate the replacement of batteries or charge new energy vehicles and meet the power exchange needs of new energy vehicles, it is necessary to build a power exchange station.

With the rapid popularization of new energy vehicles, more power exchange stations need to be built to meet the demand, while the traditional construction methods are mostly one-piece structures, which need to transport related materials to the site before construction, and the power exchange station itself has a large space. The corresponding construction material specifications are also large, which is not only unfavorable for transportation and high cost, but also has a long construction period, and is also unfavorable for later expansion and upgrading of power exchange equipment.

The Chinese patent application with publication number CN106043247A discloses a modular and expandable power exchange equipment and a battery rack. The battery storage modules in the battery rack are stacked together in a modular manner, and the battery transfer device can pass through the battery storage module. However, all of them are splicing of the charging bins in the battery rack. When the power exchange station is constructed, the charging bins still need to be spliced in sequence, and the power exchange station itself cannot be modularized. The Chinese patent application with publication number CN111717062A discloses a power exchange system for heavy-duty trucks. Covers a large area.
