When the button is pressed, the button pushes the cam structure to move vertically (z direction), and the cam structure drives the rolling element to roll and move along the transverse direction (x direction), so that the rolling element drives the buckle structure to move towards the first shell 10 in a contracting manner, and the buckle structure is separated from the clamping groove.

In order to ensure a pressing feel, so that a user can conveniently open the electronic device 100, the force required to press the button to drive the buckle structure to shrink is usually smaller, that is, the button can be activated to open the electronic device 100 by applying a smaller force. In the actual use process, except for the use scene that is normally pressed to start, the situation of false touch easily occurs, and the start button turns on the electronic device 100. For example, when the electronic device 100 is in a folded state, the electronic device 100 is held, and the thumb and the jaw of the thumb are usually corresponding to the positions of the buttons, so that the buttons are easily pressed, resulting in the opening of the electronic device 100. Or, the electronic device 100 is pressed by an external force, for example, the electronic device 100 is placed in a pocket, a bag or other environment, so that the electronic device is easily pressed by touching with other articles, and the button is started. The phenomenon that the button is suddenly opened by touching by mistake obviously reduces the stability and the use experience of the electronic device 100, and meanwhile, the sudden opening of the electronic device 100 leads to the sudden unfolding of the flexible display screen 40, which may cause damage to the flexible display screen 40.

The foldable electronic device 100 provided by the embodiment of the application has the function of preventing false touch, can effectively prevent the phenomenon that the electronic device suddenly opens due to false touch of a button in the use process, and remarkably improves the reliability and the use experience of the electronic device.

Specifically, referring to fig. 4 and 5, in the embodiment of the present application, the button assembly 60 includes a first button 61 and a second button 62, and the first button 61 and the second button 62 are rotatably disposed on the button bracket 50, and specifically, the first button 61 and the second button 62 are rotatably engaged with the button bracket 50 through a rotation shaft 64.

Wherein the button holder 50 may include a bottom wall 51 and side walls 52 provided on opposite sides of the bottom wall 51, and the first button 61 may be provided on a side of the second button 62 facing away from the bottom wall 51 of the button holder 50, and a pressing force directly acts on the first button 61 when the button assembly 60 is pressed.

With continued reference to fig. 4 and 5, the second button 62 is provided with a locking element 621, and, as shown in fig. 6, the second housing 20 is provided with a locking position 21 for cooperating with the locking element 621. When the electronic device 100 is in the folded state, the clamping piece 621 extends out of the first end of the first housing 10 and is located in the clamping position 21.

Specifically, referring to fig. 6, with an end of the second housing 20 facing the first housing 10 as a first end of the second housing 20, an engagement structure 211 may be provided on the first end of the second housing 20, and the engagement structure 211 may form the above-mentioned engagement position 21 with an end wall of the first end of the second housing 20. For example, the clamping structure 211 may be an L-shaped limiting structure, and the clamping position 21 formed by the L-shaped limiting structure and the second housing 20 is a clamping groove.

The clamping piece 621 extends into the clamping groove, so that the clamping structure 211 can play a limiting role on the clamping piece 621, and the clamping piece 621 is fixed in the clamping position 21, so that the first shell 10 and the second shell 20 are kept in a folded state. The fastening element 621 may have an inverted L-shaped structure, and a groove may be formed between the fastening element 621 and the side wall of the second button 62, so that the fastening element may be better matched with the fastening structure 211. Specifically, the notch of the groove formed by the fastening piece 621 and the second button 62 may face the bottom wall 51 of the button bracket 50, and in the folded state, the notch of the fastening groove formed by the fastening structure 211 and the second housing 20 is opposite to the notch of the groove formed by the fastening piece 621 and the second button 62.

When the electronic apparatus 100 is to be opened, referring to fig. 6, the first button 61 is pressed (a pressing force in the z direction as shown in fig. 6 is applied), and since the first button 61 and the second button 62 are both rotatably connected to the button holder 50, the first button 61 pushes the second button 62 to rotate relative to the button holder 50, so that the engaging piece 621 on the second button 62 moves in a direction opposite to the pressing force, that is, the engaging piece 621 lifts (moves in the z1 direction as shown in fig. 6), thereby disengaging the engaging piece 621 from the engaging position 21, and the first casing 10 and the second casing 20 can be relatively unfolded.

A second elastic member 63 may be further disposed in the first housing 10, one end of the second elastic member 63 may abut against the second button 62, and the other end of the second elastic member 63 may abut against the bottom wall 51 of the button bracket 50. Thus, when the first button 61 is pressed, the second elastic member 63 is compressed by the pressing force, the engaging member 621 is disengaged from the engaging position 21, and the first housing 10 and the second housing 20 are relatively rotated to be unfolded. After the pressing force on the first button 61 is removed, the compressed second elastic member 63 rebounds, and the rebounding force acts on the second button 62 to push the second button 62 and the first button 61, so that the first button 61 and the second button 62 are restored to the original positions, and the next starting pressing is facilitated.

In the embodiment of the present application, in order to prevent the false touch, the button is activated, and the electronic device 100 is suddenly turned on. As shown in fig. 7, a first abutment 611 and a second abutment 511 are provided on both sides of the first button 61 opposite to the bottom wall 51, respectively, such as a first abutment 611 provided on a side of the first button 61 facing the bottom wall 51 and a second abutment 511 provided on a side of the button holder 50 facing the first button 61.

The first button 61 is slidably disposed with respect to the second button 62, so that the electronic device 100 is in an unlocked state or a locked state, that is, the first button 61 is slidably disposed with respect to the second button 62, so that the electronic device 100 is switched between the unlocked state or the locked state.

Specifically, referring to fig. 7, when the electronic device 100 is in the unlocked state, the first abutting piece 611 and the second abutting piece 511 are disposed in a staggered manner. Wherein, the offset arrangement means that the vertical projection of the first abutting piece 611 and the second abutting piece 511 on the bottom wall 51 of the button bracket 50 is not overlapped, that is, the first abutting piece 611 and the second abutting piece 511 are not overlapped but offset with each other in the z direction. Thus, when the first button 61 is pressed, the first button 61 can push the second button 62 to rotate relative to the base, so that the clamping piece 621 on the second button 62 moves in a direction opposite to the pressing force, that is, the clamping piece 621 is lifted, and thus the clamping piece 621 is separated from the clamping position 21, and the first casing 10 and the second casing 20 can be relatively unfolded. That is, when the electronic device 100 is in the unlocked state, pressing the button can drive the clamping piece 621 to disengage from the clamping position 21, and the first housing 10 and the second housing 20 can be relatively unfolded to open the electronic device 100.

Referring to fig. 8 and 9, when the electronic device 100 is in the locked state, the first abutting piece 611 and the second abutting piece 511 are disposed opposite to each other, wherein the opposite arrangement means that vertical projections of the first abutting piece 611 and the second abutting piece 511 on the bottom wall 51 of the button bracket 50 at least partially overlap, that is, the first abutting piece 611 and the second abutting piece 511 at least partially overlap in the z-direction. Thus, when the first button 61 is pressed, the first abutting piece 611 and the second abutting piece 511 abut against each other, and the button cannot be continuously pressed, that is, the second button 62 cannot be driven to rotate relative to the base by the first button 61, the clamping piece 621 of the second button 62 is still located in the clamping position 21 and cannot be separated from the clamping position 21, the first casing 10 and the second casing 20 are kept locked, and the first casing 10 and the second casing 20 cannot be relatively unfolded, that is, the electronic device 100 cannot be opened, so that the electronic device 100 is kept in a folded state. That is, in the locked state, even if the button is touched by a mistake such as pressing, the first button 61 and the second button 62 cannot rotate relative to the base, the engaging piece 621 cannot be separated from the engaging position 21, and the electronic apparatus 100 cannot be opened.

In this way, during the use process, the electronic device 100 can be switched between the unlocking state and the locking state by sliding the first button 61, when the electronic device 100 is required to be kept in the folded state, the first button 61 can be controlled in a sliding manner, so that the electronic device 100 is in the locking state, and the electronic device 100 cannot be opened by pressing the first button 61 in the state, thereby effectively preventing the phenomenon that the electronic device 100 is opened due to the fact that the electronic device 100 is touched by mistake under the conditions of holding or being pressed, for example, improving the stability of the electronic device 100 and improving the use experience of users. Meanwhile, damage to the flexible display screen 40 caused by suddenly opening the flexible display screen 40 of the electronic device 100 can be avoided, and the performance of the electronic device 100 is further ensured.

When the electronic device 100 is required to be opened for unfolding, the first button 61 can be controlled in a sliding manner, so that the electronic device 100 is in an unlocked state, and the electronic device 100 can be opened by pressing the first button 61.

Specifically, with continued reference to fig. 9, the first abutment 611 may be located at an end of the first button 61 facing away from the second housing 20, and the second abutment 511 may be located at an end of the button support 50 facing away from the second housing 20, where the first button 61 is capable of sliding toward or away from the second housing 20 relative to the second button 62.

When the first button 61 slides relative to the second button 62 toward the second housing 20, as shown in fig. 10 and 11, the first abutting piece 611 and the second abutting piece 511 are finally arranged in a staggered manner, that is, there is no overlapping portion between the first abutting piece 611 and the second abutting piece 511 in the z direction, when the first button 61 is pressed, the first button 61 can push the second button 62, the first button 61 and the second button 62 rotate relative to the button bracket 50 through the rotating shaft, the clamping piece 621 of the second button 62 moves in a direction opposite to the pressing force, the clamping piece 621 lifts and breaks away from the clamping position 21, and the first housing 10 and the second housing 20 can be relatively unfolded to open the electronic device 100.

When the first button 61 slides against the second button 62 and back against the second housing 20, as shown in fig. 12 and 13, the first abutting piece 611 and the second abutting piece 511 are disposed opposite to each other, that is, the first abutting piece 611 and the second abutting piece 511 partially overlap in the z direction, and when the first button 61 is pressed, the first abutting piece 611 of the first button 61 abuts against the second abutting piece 511 on the button bracket 50, the first button 61 and the second button 62 cannot rotate against the button bracket 50, the clamping piece 621 cannot move further and cannot be separated from the clamping position 21, and the electronic device 100 cannot be opened and is in a folded state.
