Referring to fig. 2 to 5, the present application provides an electronic device 100, which may include but is not limited to: a middle frame 10, a control component 20 and a detection component 30.

The middle frame 10 may include an elastic sheet 122, and the elastic sheet 122 is used for buffering the impact generated when the electronic device 100 is dropped. The control assembly 20 is connected with the elastic sheet 122 in a snap-fit manner, and is used for controlling whether the elastic sheet 122 is ejected or not. The detection component 30 is electrically connected to the control component 20 and configured to detect whether the electronic device 100 is in a falling state, and if it is determined that the electronic device 100 is in the falling state, the detection component 30 sends an instruction to the control component 20 to pop up the elastic sheet 122, so as to protect the electronic device 100.

Referring to fig. 6 to 8, specifically, the middle frame 10 may include a middle plate 11 and a frame 12, wherein the middle plate 11 is received in the frame 12, and an edge of the middle plate 11 is fixedly connected to an inner wall of the frame 12, that is, the frame 12 receives the middle plate 11 and an inner wall of the frame 12 is fixedly connected to an edge of the middle plate 11. At least one corner of the middle plate 11 is provided with a first fastener 111. The frame 12 includes a main body 121 and an elastic piece 122 having one end connected to the main body 121, the main body 121 has a receiving hole 1210 corresponding to the first fastener 111, and the elastic piece 122 can be received in the receiving hole 1210. The surface of the elastic piece 122 facing the middle plate 11 is provided with a second latch 1121 corresponding to the first latch 111.

When the first locking member 111 is connected to the corresponding second locking member 1121 in a locking manner, the elastic piece 122 is accommodated in the corresponding accommodating hole 1210, and when the first locking member 111 is disconnected from the corresponding second locking member 1121, the elastic piece 122 is ejected from the corresponding accommodating hole 1210. That is, the elastic piece 122 may be configured to allow the first locking element 111 to be locked with the corresponding second locking element 1121 to be received in the corresponding receiving hole 1210, and may also be configured to allow the first locking element 111 to be unlocked from the corresponding second locking element 1121 to be ejected out of the corresponding receiving hole 1210.

Optionally, the middle plate 11 may be rectangular and have four rounded corners, and the number of the first fasteners 111 is four and is located at the four corners of the middle plate 11 respectively. The main body 121 may have a rectangular hollow frame structure with rounded corners, and the number of the receiving holes 1210 is four and is located at the four corners of the main body 121. Through the manner, each corner of the main body part 121 is respectively provided with the accommodating hole 1210 for accommodating the elastic sheet 122, so that the cushion protection effect can be achieved no matter which corner of the middle frame 10 falls to the ground, and the reliability of falling protection is improved.

Optionally, the receiving holes 1210 are arc-shaped and parallel to the middle plate 11, that is, the plane where the receiving holes 1210 are arc-shaped is parallel to the middle plate 11. The arc length of the receiving hole 1210 corresponds to the arc length of the rounded corner of the body portion 121 to increase the contact area with the ground when the middle frame 10 falls to the ground.

Specifically, the main body 121 includes two first bending portions 1211 and two second bending portions 1212 connected to the two first bending portions 1211, the connection portion between each first bending portion 1211 and one second bending portion 1212 is rounded, and the receiving hole 1210 is located at the connection portion between the first bending portion 1211 and the second bending portion 1212. Since the arc length of the receiving hole 1210 corresponds to the arc length of the fillet of the main body 121, no matter the first bending portion 1211 falls to the ground first or the second bending portion 1212 falls to the ground first, the elastic piece 122 received in the receiving hole 1210 always has a buffering protection effect, so as to prevent the receiving hole 1210 from being separately disposed on the first bending portion 1211 or the second bending portion 1212.

Alternatively, the elastic piece 122 can be received in the receiving hole 1210, and the elastic piece 122 is flush with the outer surface of the main body portion 121, so that the outer surface of the middle frame 10 is neat and beautiful. In other embodiments, the elastic piece 122 may also be partially accommodated in the accommodating hole 1210, that is, the elastic piece 122 protrudes from the outer surface of the main body 121; or the elastic sheet 122 is completely received in the receiving hole 1210, that is, the elastic sheet 122 is recessed in the outer surface of the main body 121.

Optionally, the middle frame 10 may further include an elastic body 13. The elastic body 13 is fixed on the middle plate 11, and the first latch 111 is fixedly connected with the middle plate 11 through the elastic body 13. The elastic body 13 can be shaped under the action of external force, so that the first fastening part 111 is far away from the corresponding second fastening part 1121. The elastic body 13 can also be restored to the original state after the external force is cancelled. Specifically, the elastic body 13 drives the first fastening part 111 to be away from the corresponding second fastening part 1121 under the action of an external force, so that the first fastening part 111 and the corresponding second fastening part 1121 are released from being fastened and connected, and the elastic part 15 can be ejected from the accommodating hole 1210; after the elastic piece 122 is popped out, the elastic body 13 is restored to the initial state, that is, the first fastening piece 111 returns to the original position, so that the first fastening piece 111 can be fastened and connected with the corresponding second fastening piece 1121, and the elastic piece 122 can be ensured to be accommodated in the accommodating hole 1210.

Referring to fig. 9 and 10, in the embodiment, the elastic sheet 122 is made of a memory alloy, and one end of the elastic sheet 122 is fixedly connected to the main body 121, or the elastic sheet 122 and the main body 121 are integrally formed. When the first fastening member 111 is fastened to the corresponding second fastening member 1121, the elastic sheet 122 is accommodated in the accommodating hole 1210 and is in a deformed state, and at this time, the electronic device 100 is in a daily use state. When the first locking element 111 is disengaged from the corresponding second locking element 1121, the elastic piece 122 is ejected from the corresponding receiving hole 1210 and is in a free state, and at this time, the electronic device 100 is in a falling protection state.

The receiving holes 1210 are formed in the main body 121, so that the continuity and the structural strength of the frame 12 are not damaged, the elastic pieces 122 are a part of the frame 12, and the elastic pieces 122 are received in the receiving holes 1210, so that the receiving holes 1210 can be sealed without occupying the internal space of the middle frame 10, and the middle frame 10 is beautiful and has a buffering function.

Referring to fig. 11 and 12, in a variation of the present embodiment, the middle frame 10 may further include a torsion spring 14. In this modification, one end of the elastic piece 122 is rotatably connected to the main body 121 through the rotating shaft 101, wherein the torsion spring 14 is accommodated in the main body 121 and disposed close to the rotating shaft 101, and two torsion arms of the torsion spring 14 are respectively fixedly connected to the main body 121 and the elastic piece 122. When the first fastening member 111 is fastened to the corresponding second fastening member 1121, the torsion spring 14 deforms to accommodate the elastic piece 122 in the accommodating hole 1210; when the first locking member 111 is disengaged from the corresponding second locking member 1121, the torsion spring 14 returns to the free state to make the elastic piece 122 pop out of the receiving hole 1210. That is, the torsion spring 14 may be configured such that the first locking element 111 is locked with the corresponding second locking element 1121 to deform and the elastic piece 122 is accommodated in the corresponding accommodating hole 1210, and may also be configured such that the first locking element 111 is unlocked from the corresponding second locking element 1121 to restore the free state and the elastic piece 122 is ejected out of the corresponding accommodating hole 1210.

In this modification, since the elastic piece 122 is rotatably connected to the main body 121 via the rotating shaft 101, the elastic piece 122 may be made of the same metal alloy as that of the main body 121, or may be made of an intersecting or polymer material. In addition, the all-metal shell has a strong shielding effect on signals, and the elastic sheet 122 is made of a non-metal material, so that the buffering protection effect can be achieved, and the shielding of the metal shell on the signals can be weakened. In addition, the elastic piece 122 is accommodated in the accommodating hole 1210, so that the accommodating hole 1210 can be closed without occupying the internal space of the middle frame 10, and the middle frame 10 is beautiful and has a buffering function.

Referring to fig. 13 and 14, in another variation of the present embodiment, the middle frame 10 may further include an elastic member 15, such as a spring. In this modification, one end of the elastic piece 122 is rotatably connected to the main body 121 through the rotating shaft 101, wherein the elastic piece 15 is accommodated in the main body 121 and two ends of the elastic piece 15 are respectively connected to the middle plate 11 and the surface of the elastic piece 122 facing the middle plate 11. When the first fastening member 111 is fastened to the corresponding second fastening member 1121, the elastic member 15 is deformed (compressed) to accommodate the elastic piece 122 in the accommodating hole 1210; when the first locking member 111 is disengaged from the corresponding second locking member 1121, the elastic member 15 returns to the original state to make the elastic piece 122 pop out of the receiving hole 1210. That is, the elastic element 15 may be configured such that the first locking element 111 is locked with the corresponding second locking element 1121 to deform so as to allow the elastic sheet 122 to be accommodated in the corresponding accommodating hole 1210, and may also be configured such that the first locking element 111 is unlocked from the corresponding second locking element 1121 to restore the free state so as to allow the elastic sheet 122 to be ejected out of the corresponding accommodating hole 1210.

In this modification, since the elastic piece 122 is rotatably connected to the main body 121 via the rotating shaft 101, the elastic piece 122 may be made of the same metal alloy as that of the main body 121, or may be made of an intersecting or polymer material. In addition, the all-metal housing has a strong shielding effect on signals, and the elastic sheet 122 is made of a non-metal material, so that the buffering protection effect can be achieved, and the transmission of the signals can be enhanced. In addition, the elastic piece 122 is accommodated in the accommodating hole 1210, so that the accommodating hole 1210 can be closed without occupying the internal space of the middle frame 10, and the middle frame 10 is beautiful and has a buffering function.

In the middle frame 10 provided by the present application, the main body portion 121 is provided with the accommodating hole 1210 for accommodating the elastic piece 122, so that the elastic piece 122 does not occupy the internal space of the main body portion 121, the thickness of the middle frame 10 is increased, and the middle frame 10 can be ejected from the accommodating hole 1210 to perform buffering protection on the middle frame 10. The middle frame 10 provided by the application can play a role in buffering the falling of the middle frame 10 under the condition of not occupying the internal space of the middle frame 10 and increasing the thickness of the middle frame 10.

When the elastic body 13 is in a deformed state under the action of the control component 20, that is, the control component 20 provides an external force to the elastic body 13 away from the second buckling part 1121, the first buckling part 111 is connected to the second buckling part 1121 in a releasing manner. When the acting force of the control assembly 20 is cancelled and the elastic body 13 returns to the free state, the first latch 111 can be buckled with the second latch 1121.

When the electromagnet 22 is turned off, the attraction force between the fixed magnet 21 and the electromagnet 22 disappears, and the elastic body 13 can return to the original state.

Referring to fig. 5 and fig. 16, in a further modification of the present embodiment, the electromagnet 22 is fixed on the first locking member 111, the fixed magnet 21 is fixed on the middle plate 11, and after the electromagnet 22 is powered on, the fixed magnet 21 and the electromagnet 22 are attracted to each other, so that the first locking member 111 is away from the corresponding second locking member 1121.
