BATTERY SUPPORT MECHANISM AND BATTERY HEATING DEVICE

A battery support mechanism includes a base, a drive structure, and two end plate support structures. The two end plate support structures are spaced apart along a first direction on the base, and at least one of the two end plate support structures is in transmission connection to the drive structure to move along the first direction under the drive of the drive structure. The battery support mechanism provided by the present application is configured to support a battery. A distance between the two end plate support structures can be adjusted through the drive structure according to the size of the battery, so as to support batteries of different sizes with higher compatibility.
