Buckle assembly and terminal

The embodiment of the invention discloses a buckle assembly and a terminal. The buckle assembly comprises a buckle and a clamping groove; the buckle comprises a first elastic part; when the buckle is clamped with or separated from the clamping groove, the first elastic part deforms, and when the buckle is located in the clamping groove or separated from the clamping groove, the deformation of the first elastic component is recovered, a second elastic component is arranged inside or outside the first elastic component, and the second elastic component is filled with a filling material; when the environment temperature is lower than or equal to the preset temperature, the filling material is changed from the liquid state to the solid state, the first elastic component is fixed by the filling material, and at the moment, if the buckle is located in the clamping groove, the buckle is locked. The buckle assembly is used for the terminal, the terminal can be locked at a low temperature, and damage to a flexible dis
