A hinge assembly (200) includes a housing (12), a shaft (11), a fixing pin (14), a transposition mechanism (13) and a first spring (16). The housing has a circumferential wall defining a manual slot (121) and an automatic slot (123). Each of the manual slot and the automatic slot runs through a circumferential wall thereof. The shaft defines a pin hole (1141), and the shaft is engaged in the housing. The fixing pin passes through the pin hole of the shaft. One end of the fixing pin is alternatively received in the manual slot or the automatic slot. The transposition mechanism is configured for switching the pin from the manual slot to the automatic slot. The first spring provides an elastic force causing the housing to move relative to the shaft when the pin breaks away from the manual slot.
