Abstract

The present application relates to a battery swap apparatus and a battery swap system for replacing a battery of an electrical device, which comprises: a movable base configured to drive the battery swap apparatus to move; two battery swap mechanisms arranged on the movable base, the two battery swap mechanisms being configured to carry two batteries so that the battery swap apparatus replaces the two batteries at the same time; and an exchange mechanism arranged on the movable base, the exchange mechanism being configured to drive the two battery swap mechanisms to exchange positions. The battery swap apparatus provided by the present application can replace two batteries at the same time, the number of times of traveling in the battery swap process is small, and the battery swap efficiency is high, which solves the problem of low battery swap efficiency at present.

Claims (17)

1 . A battery swap apparatus for replacing a battery of an electrical device, comprising:

a movable base configured to drive the battery swap apparatus to move;

two battery swap structures arranged on the movable base, the two battery swap structures being configured to carry two batteries so that the battery swap apparatus replaces the two batteries at the same time; and

an exchange structure arranged on the movable base, the exchange structure being configured to drive the two battery swap structures to exchange positions,

wherein each of the battery swap structures comprises a locking and unlocking assembly and a protective enclosure, the locking and unlocking assembly comprises a base plate and a locking and unlocking structure, the locking and unlocking structure is configured for locking or unlocking the battery, the protective enclosure covers the top of the base plate, and the protective enclosure is provided with a first opening through which the locking and unlocking structure extends, and

the locking and unlocking assembly further comprises a positioning structure for positioning the battery and a supporting structure for supporting the battery, and the protective enclosure is provided with a second opening through which the positioning structure extends and a third opening through which the supporting structure extends.

2 . The battery swap apparatus according to claim 1 , wherein the exchange structure comprises a driver and a rotating base, the driver is configured to drive the rotating base to rotate, and the two battery swap structures are mounted on the rotating base and are symmetrically arranged about a rotation axis of the rotating base.

3 . The battery swap apparatus according to claim 2 , wherein the driver is fixed to the movable base, the exchange structure further comprises a first gear and a second gear that mesh with each other, the first gear is mounted on an output end of the driver, and the second gear is fixed on the rotating base.

4 . The battery swap apparatus according to claim 1 , wherein the two battery swap structures are arranged at intervals.

5 . The battery swap apparatus according to claim 1 , wherein a side of the protective enclosure away from the locking and unlocking assembly is provided with a slot, and the slot is configured for insertion of a fork to pick and place the battery.

6 . The battery swap apparatus according to claim 1 , wherein each of the battery swap structures further comprises a lift assembly, and the lift assembly is configured to lift the locking and unlocking assembly.

7 . The battery swap apparatus according to claim 6 , wherein the locking and unlocking assembly is floatingly connected to the lift assembly.

8 . A battery swap system, comprising:
