Abstract

A circumferential locking mechanism, a battery securing device comprising same, a battery pack, and a vehicle are provided. The circumferential locking mechanism (100) comprises: a first component (110), the first component (110) comprising a first body (111) and pins (112) extending from the first body (111) in an axial direction, the pins (112) being distributed on the first body (111) along a first circumference; a second component (120), the second component (120) comprising a second body (121) and a limiting face (122) on the second body (121), the limiting face (122) extending in a circumferential direction and comprising segments, the radius of the limiting face (122) tapering in both the axial and circumferential directions at the segments; and a third component for impelling the first component (110) to engage with the second component (120), wherein the first component (110) and the second component (120) are arranged such that the first circumference and the limiting face (122) are coaxial, and when the first component (110) is engaged with the second component (120), the pins (112) abut against the limiting face (122). The pins (112) can be fitted to the limiting face (122) by means of the foregoing structure to complete continuous locking.
