Abstract: Provided are a locking structure, a housing assembly, and an electronic device. The locking structure includes first and second structural bodies, a pressing member, and a clamped member. The first structural body is provided with first and second mounting portions. The second structural body includes a locking portion. The pressing member is movably provided at the first mounting portion. The clamped member is movably provided at the second mounting portion, and can be engaged with the locking portion. In mounting the second structural body to the first structural body, the clamped member is driven by the locking portion to move, and is restored so as to be engaged with the locking portion. In detaching the second structural body from the first structural body, the pressing member is pressed by an external force to drive the clamped member to move so as to be disengaged from the locking portion.
