Title: CIRCUMFERENTIAL LOCK MECHANISM, BATTERY LOCKING DEVICE, POWER BATTERY PACK AND VEHICLE
Abstract:
A circumferential lock mechanism, a battery locking device comprising same, a power battery pack and a vehicle. The circumferential locking mechanism (100) comprises: a first component (110), said first component comprising a first body (111) and pins (112) extending from the first body (111) along an axial direction, the pins (112) being distributed along a first circumference on the first body (111); a second component (120), said second component (120) comprising a second body (121) and a limiting surface (122) on the second body (121), said limiting surface (122) extending along a circumferential direction and comprising segments, a radius of the limiting surface (122) tapering along both an axial direction and a circumferential direction of said segments; and a third component forcing the first component (110) and the second component (120) to engage, the first component (110) and the second component (120) being arranged so that the first circumference and the limiting surface (122) are coaxial, and when the first component (110) and the second component (120) are engaged, the pins (112) abut the limiting surface (122). Pins (112) and a limiting surface (122) may be fit by means of the described structure, making complete continuous locking possible.
