Thus, the pop-up portion 22 of the protection member 2 can protect the display module 5, and when the terminal 100 is landed, the pop-up portion 22 of the protection member 2 can first contact with the ground to absorb the impact of the ground on the terminal 100, thereby effectively preventing the display module 5 from being damaged by falling, and further protecting the terminal 100.

When the terminal 100 is landed, the permanent magnet 61 and the electromagnetic coil 62 are no longer energized, for example, the electromagnetic coil 62 is connected to the main board 8, the main board 8 can cut off the energization of the electromagnetic coil 62, so that the electromagnetic coil 62 is no longer magnetized, and the pop-up portion 22 of the protection member 2 is switched from the extended state to the retracted state by its own elastic force; or when the terminal 100 is landed, the direction of the current on the electromagnetic coil 62 is changed to make the permanent magnet 61 and the electromagnetic coil 62 have an attraction force, so that the pop-up portion 22 of the protector 2 is switched from the expanded state to the contracted state by the attraction force and the elastic force of itself; when the pop-up portion 22 is in the collapsed state, the pop-up portion 22 is flush with or lower than the external appearance surface of the display unit 5. Thereby, it is possible to prevent the pop-up portion 22 of the protector 2 from affecting the aesthetic appearance of the terminal 100.

Further, as shown in fig. 20, 21, 23 and 24, the electromagnetic coils 62 are located in the housing 1, the electromagnetic coils 62 are arranged in plurality at intervals along the circumferential direction of the housing 1, the permanent magnets 61 are located in the ejecting portion 22, the permanent magnets 61 are arranged in plurality at intervals along the length direction of the ejecting portion 22, and the electromagnetic coils 62 and the permanent magnets 61 are arranged in one-to-one correspondence.

In some embodiments of the present invention, as shown in fig. 19 and 23, the cam 64 is plural in number spaced apart in the circumferential direction of the housing 1. Thus, by providing the plurality of cams 64, the strength of the force acting between the protector 2 and the housing 1 can be enhanced, and the plurality of cams 64 are provided at intervals in the circumferential direction of the terminal 100, so that the smoothness of the protector 2 when it is moved can be improved.

In some embodiments of the present invention, the terminal 100 may further include: a sensor for detecting a falling state of the terminal 100, and a controller connected to the sensor, for controlling the second driving assembly 6 to drive the ejector 22 from a contracted state to an expanded state or to drive the ejector 22 from an expanded state to a contracted state, according to the falling state of the terminal 100. The sensor may detect a state in which the terminal 100 is located, for example, the sensor may detect whether the terminal 100 is in a falling state or a stationary state.

As shown in fig. 6 and 24, when the sensor detects that the terminal 100 is in a falling state, the sensor transmits a detected signal to the controller, and the controller controls the driving motor 63 to be energized and the opposing force between the electromagnetic coil 62 and the permanent magnet 61, for example, the controller controls the electromagnetic coil 62 and the driving motor 63 to be energized, so that the opposing force exists between the electromagnetic coil 62 and the permanent magnet 61, and meanwhile the driving motor 63 drives the cam 64 to rotate, and the protection member 2 moves towards a direction away from the housing 1 under the action of the opposing force and the cam 64, and is switched from a retracted state to an extended state to protect the display assembly 5 from being damaged; when the terminal 100 is not dropped or falls down to the ground, the sensor transmits a detected signal to the controller, and the controller may change the direction of the current of the energized coil of the electromagnetic coil 62, or cut off the current of the electromagnetic coil 62, and change the rotation direction of the driving motor 63. For example, the controller changes the direction of the current supplied to the solenoid 62 and the rotation direction of the driving motor 63, so that the solenoid 62 and the permanent magnet 61 have an attractive force therebetween, and the cam 64 can rotate to an initial position, at which the protection member 2 is switched from the extended state to the retracted state by the elasticity of itself and the attractive force.

Further, the sensor is at least one of a gyroscope, an acceleration sensor, a gravity sensor, an inertial sensor, a camera, a height sensor, and a motion sensor. Thereby, it is possible to sensitively and accurately detect whether the terminal 100 is in a dropped state. For example, when the sensor is an acceleration sensor, when the sensor detects that the terminal 100 has acceleration, the sensor transmits the detected acceleration information to the controller, and the controller determines that the terminal 100 is in a falling state and controls the driving motor 63 and the electromagnetic coil 62 to be energized, so that an opposing force exists between the electromagnetic coil 62 and the permanent magnet 61, and the driving motor 63 drives the cam 64 to rotate, and further the pop-up portion 22 of the protection member 2 is switched from a retracted state to an extended state, so as to protect the display assembly 5 from being damaged.
