As shown in fig. 8, 9, 38 and 39, the protector 3 includes a fixing portion 31 and at least one ejection portion 32, and the fixing portion 31 is fixedly connected to the housing assembly 1. The at least one ejecting portion 32 is elastically connected to the fixing portion 31, that is, the ejecting portion 32 is deformed by a force, for example, is elongated by a force, the ejecting portion 32 can be restored to an initial state by being connected to the fixing portion 31 without a force, and the fixing portion 31 and the ejecting portion 32 can be integrally formed. As shown in fig. 7, 10, 17, 24, 31, and 32, the cam 61 of the housing assembly 1 faces the ejecting portion 32, and the ejecting portion 32 abuts against the outer peripheral surface of the cam 61.

The cam 61 drives the ejecting part 32 to move between a retracted state and an extended state, when the ejecting part 32 is in the extended state, the ejecting part 32 exceeds the appearance surface M1 of the display assembly 2; when the pop-up portion 32 is in the retracted state, the pop-up portion 32 is flush with the appearance surface M1 of the display module 2 or lower than the appearance surface M1 of the display module 2, so that the pop-up portion 32 of the protection member 3 can be prevented from affecting the appearance of the electronic device 100.

It should be noted that, when the electronic device 100 is in a state of falling, etc., the driving motor 62 drives the cam 61 to rotate, and the outer peripheral surface of the cam 61 drives the ejecting portion 32 of the protecting member 3, so that the ejecting portion 32 of the protecting member 3 is switched from the retracted state to the extended state. When the pop-up portion 32 is in the extended state, at least part of the appearance surface M1 of the display module 2 is wrapped by the pop-up portion 32. Therefore, the pop-up portion 32 of the protection member 3 can protect the display module 2, and when the electronic device 100 falls to the ground, the pop-up portion 32 of the protection member 3 can first contact with the ground to absorb the impact of the ground on the electronic device 100, so that the display module 2 is effectively prevented from being damaged by falling, and the electronic device 100 is protected.

When the electronic device 100 is landed, for example, the cam 61 may be rotated in the reverse direction, so that the ejecting portion 32 of the protection member 3 is switched from the extended state to the retracted state by its own elastic force. When the pop-up portion 32 is in the collapsed state, the pop-up portion 32 is flush with the appearance surface M1 of the display module 2 or lower than the appearance surface M1 of the display module 2. Therefore, the ejection part 32 of the protection member 3 can be prevented from affecting the appearance of the electronic device 100.

For example, the protection member 3 may include two spaced-apart segments, and the two segments of the protection member 3 are respectively located on opposite left and right sides of the display module 2 (in the left-right direction shown in fig. 1), but of course, the two segments of the protection member 3 may also be respectively located on upper and lower sides of the display module 2 (in the up-down direction shown in fig. 1). This can reduce the length of the protector 3 and save material cost.

Further, the end of at least one segment of the protector 3 is a pop-up portion 32, and the rest of the protector 3 is a fixing portion 31. For example, two protection members 3 are respectively disposed on the left and right sides of the display module 2, wherein one end of one protection member 3 is terminated with the pop-up portion 32, and the rest of the protection member 3, i.e., the rest of the one protection member and the other protection member 3, are the fixing portions 31.

In some embodiments of the present invention, the electronic device 100 further includes a sensor for detecting a falling state of the electronic device 100, and a controller connected to the sensor, wherein the controller is connected to a main board of the electronic device 100, and controls the driving motor 62 to rotate the cam 61 to drive the pop-up portion 32 from the retracted state to the extended state or drive the pop-up portion 32 from the extended state to the retracted state according to the falling state of the electronic device 100. The sensor may detect a state in which the electronic device 100 is located, for example, the sensor may detect whether the electronic device 100 is in a falling state or a stationary state.

When the sensor detects that the electronic device 100 is in a falling state, the sensor transmits a detected signal to the controller, the controller controls the driving motor 62, the driving motor 62 drives the cam 61 to rotate, and the protection member 3 is switched from a contraction state to an extension state under the driving action of the cam 61; when the electronic device 100 does not fall or falls to the ground, the sensor transmits a detected signal to the controller, the controller controls the driving motor 62 not to rotate or rotate in the opposite direction, and the protection member 3 is in the contracted state or switched from the expanded state to the contracted state under the action of the elasticity of the protection member.

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. Therefore, whether the electronic device 100 is in a falling state or not can be sensitively and accurately detected. For example, when the sensor is an acceleration sensor, and the sensor detects that the electronic device 100 has acceleration, the sensor transmits the detected acceleration information to the controller, and the controller determines that the electronic device 100 is in a falling state and controls the driving motor 62 to rotate the cam 61 so as to switch the ejecting portion 32 of the protecting member 3 from the retracted state to the extended state, thereby protecting the display assembly 2 from being damaged.
