[0039] As Figure 1As shown, the electronic device 10 of the embodiment of the present application comprises a shell assembly 100 and a flexible display screen (not shown). The shell assembly 100 is a hollow structure. The electronic device 10 can further comprise a circuit board (not shown) and a battery (not shown), both of which can be arranged inside the shell assembly 100. The circuit board can integrate a processor, a power management module, a storage unit, a baseband chip and the like of the electronic device 10. The flexible display screen is in communication connection with the circuit board, and the battery can supply power to the flexible display screen and electronic elements on the circuit board. Of course, the electronic device 10 can further comprise a camera module (not shown), which is in communication connection with the circuit board, and the battery can supply power to the camera module. It can be understood that the electronic device 10 of the embodiment of the present application includes but is not limited to a terminal device such as a mobile phone, a tablet computer or other portable electronic device 10. In the embodiment of the present application, a mobile phone is taken as an example for illustration.

[0040] Continuing to refer to Figure 1 In the embodiment of the present application, the shell assembly 100 comprises a fixed end 110 and a moving end 120, the moving end 120 moves relative to the fixed end 110 along a predetermined direction and has a first position close to the fixed end 110 and a second position away from the fixed end 110. When the moving end 120 is at the first position, the shell assembly 100 is in a folded state, and when the moving end 120 is at the second position, the shell assembly 100 is in an unfolded state. The moving end 120 switches between the first position and the second position, so that the shell assembly 100 switches between the folded state and the unfolded state. The shell assembly 100 switches between the folded state and the unfolded state to adjust the display area of the flexible display screen. It can be understood that when the shell assembly 100 is in the unfolded state, the display area available for display of the flexible display screen is larger, so as to improve the use experience of the electronic device 10, and at this time the entire electronic device 10 is in the unfolded state and has a larger size. When the shell assembly 100 is in the folded state, the display area available for display of the flexible display screen is smaller, and at this time the entire electronic device 10 is in the folded state and has a relatively smaller size, so as to facilitate carrying.

[0041] Specifically, the electronic device 10 has a width direction, a length direction and a thickness direction, the positive direction and the negative direction of the X axis are defined as the width direction, the positive direction and the negative direction of the Y axis are defined as the length direction, and the positive direction and the negative direction of the Z axis are defined as the thickness direction. Then in the Figure 1 embodiment, the leftmost side of the width direction of the electronic device 10 is one end of the fixed end 110 away from the moving end 120, and the rightmost side of the width direction of the electronic device 10 is one end of the moving end 120 away from the fixed end 110. In addition, in the present application, the predetermined direction is the width direction of the electronic device 10, and in other embodiments, the predetermined direction can also be the length direction of the electronic device 10.

[0042] In combination Figure 1 withFigure 2 As shown in the embodiments of the present application, the electronic device 10 comprises a driving structure 200, which is connected between the moving end 120 and the fixed end 110 to drive the moving end 120 to move relative to the fixed end 110 in a predetermined direction, so as to automatically switch the shell assembly 100 between the folded state and the unfolded state.

[0043] Specifically, the driving structure 200 comprises a driving assembly 230 and a push rod 210, the push rod 210 is connected with the driving assembly 230 and moves in a predetermined direction under the driving of the driving assembly 230. Further, the driving assembly 230 is installed on the fixed end 110, and the push rod 210 is connected with the moving end 120, so that under the driving of the driving assembly 230, the push rod 210 drives the moving end 120 to move relative to the fixed end 110 in a predetermined direction, so as to switch the shell assembly 100 between the folded state and the unfolded state.

[0044] In combination Figures 1 to 4 As shown, for the push rod 210, the push rod 210 is divided into a first rod body 211 connected with the driving assembly 230 and a second rod body 212 rotationally connected with the first rod body 211 in a predetermined direction. The driving structure 200 further comprises a reset member 250 connected with the second rod body 212. The second rod body 212 rotates relative to the first rod body 211 under the action of an external force, and the reset member 250 absorbs the kinetic energy of the second rod body 212 and drives the second rod body 212 to reset after the external force is removed. As shown Figure 4 As shown, the second rod body 212 rotates relative to the first rod body 211 in a first direction under the action of an external force, and the reset member 250 drives the second rod body 212 to rotate in a second direction to reset. Specifically, the direction indicated by arrow m is defined as the first direction, and the direction indicated by arrow n is defined as the second direction.

[0045] By dividing the push rod 210 into the first rod body 211 and the second rod body 212, when an external force impacts on the second rod body 212, the external force will force the second rod body 212 to rotate relative to the first rod body 211. With the rotation of the second rod body 212 relative to the first rod body 211, the reset member 250 absorbs and stores at least part of the impact brought by the external force, thereby reducing the transmission of the impact force to the first rod body 211, and further reducing the impact on the driving assembly 230, thereby protecting the driving assembly 230, so that the driving structure has higher impact resistance.

[0046] Specifically, the second rod body 212 is connected with the moving end 120, so that when the external impact force is transmitted from the moving end 120 to the push rod 210, the impact force will act on the second rod body 212. Specifically, the external force acting on the second rod body 212 can have an angle with the predetermined direction, as shown Figure 3The external force acting on the second rod body 212 can be decomposed into a first force Fa in the vertical direction (a direction perpendicular to the predetermined direction) and a second force Fb in the predetermined direction, or the external force acting on the second rod body 212 can be entirely the first force Fa in the vertical direction. If the push rod 210 is in an integral structure, the push rod 210 will be raised like a seesaw under the action of the first force Fa, which will cause damage to the locking member in the driving assembly 230 that constitutes a lock in the vertical direction to the push rod 210. By providing the reset member 250 and dividing the push rod 210 into the first rod body 211 and the second rod body 212, the impact brought by the first force Fa can be at least absorbed, thereby reducing the impact on the driving assembly 230 and achieving the protection effect on the locking member.

[0047] In the embodiment of the present application, the driving structure 200 includes a rotating shaft 270 connected between the first rod body 211 and the second rod body 212, and the second rod body 212 rotates relative to the first rod body 211 about the axis of the rotating shaft 270. By providing the rotating shaft 270, the first rod body 211 and the second rod body 212 are allowed to rotate relative to each other. Specifically, one of the first rod body 211 and the second rod body 212 can be fixedly installed with the rotating shaft 270, and the other one rotates about the rotating shaft 270. Alternatively, the rotating shaft 270 can be arranged through the first rod body 211 and the second rod body 212, and both the first rod body 211 and the second rod body 212 can rotate about the axis of the rotating shaft 270.

[0048] Further, the reset member 250 is sleeved on the rotating shaft 270, and the reset member 250 is a torsion spring acting on the first rod body 211 and the second rod body 212. When the first force Fa forces the second rod body 212 to rotate in the first direction, the elastic potential energy of the torsion spring gradually increases, and the kinetic energy of the rotation of the second rod body 212 decreases. After the first force Fa is removed, the second rod body 212 rotates in the second direction under the action of the torsion spring, thereby gradually releasing the energy, achieving the reset of the second rod body 212, and avoiding a large impact on the driving assembly 230.

[0049] In combination Figure 2 With Figure 4 As shown in the figure, specifically, the end of the first rod body 211 is provided with a first lug 213 and a second lug 214, and the first lug 213 and the second lug 214 are arranged in the axial direction of the rotating shaft 270. The end of the second rod body 212 is provided with a third lug 215 and a fourth lug 216, and the third lug 215 and the fourth lug 216 are arranged in the axial direction of the rotating shaft 270. The rotating shaft 270 is arranged through the first lug 213, the third lug 215, the fourth lug 216, and the second lug 214 in sequence. The reset member 250 is sleeved on the rotating shaft 270 and located between the third lug 215 and the fourth lug 216. The two ends of the reset member 250 are connected to the first rod body 211 and the second rod body 212, respectively.

[0050] In the embodiments of the present application, the first rod body 211 is provided with a first limiting block 217, and the second rod body 212 is provided with a second limiting block 218. The first limiting block 217 can abut against the second limiting block 218 during the resetting of the second rod body 212, so as to maintain the push rod 210 in a predetermined state. It can be understood that the predetermined state is both the initial state of the rotation of the second rod body 212 in the first direction and the terminal state of the resetting of the second rod body 212 in the second direction, and in the predetermined state, the push rod 210 can stably drive the moving end 120 to move in the predetermined direction.

[0051] Further, in the predetermined state, the first limiting block 217 and the second limiting block 218 are in surface-to-surface contact, and the acting surfaces of the two are parallel to the predetermined direction. In this way, when the push rod 210 drives the moving end 120 to move in the predetermined direction, the first rod body 211 can only exert a pushing and pulling force on the second rod body 212 in the predetermined direction, so that the pushing and pulling force is transmitted to the moving end 120 via the second rod body 212, ensuring smooth movement of the moving end 120 in the predetermined direction, and avoiding the problem of jamming of the moving end 120 and the fixed end 110. It can be understood that the surface-to-surface contact of the first limiting block 217 and the second limiting block 218 specifically means that the acting surfaces of the first limiting block 217 and the second limiting block 218 in contact with each other are both flat surfaces, and the acting surface of the first limiting block 217 and the acting surface of the second limiting block 218 are in surface-to-surface contact with each other, so as to play a stable limiting role in the second direction.

[0052] Specifically, the first lug 213 and the second lug 214 are both provided with the first limiting block 217, and the second rod body 212 is provided with the second limiting block 218 corresponding to the positions of the first lug 213 and the second lug 214. In this way, the two first limiting blocks 217 and the two second limiting blocks 218 are in one-to-one abutment, thereby forming two abutments at both ends of the axis line of the rotation shaft 270, so as to stably maintain the push rod 210 in the predetermined state.

[0053] Specifically, the first rod body 211 and the second rod body 212 are both flat plates, and the thicknesses of the first rod body 211 and the second rod body 212 are equal. In the predetermined state, the two surfaces of the first rod body 211 in the thickness direction are flush with the two surfaces of the second rod body 212 in the thickness direction.

[0054] In combination Figure 2 With Figure 3As shown, in the embodiment of the present application, the moving end 120 is provided with a first abutting surface 121, and the second rod body 212 is provided with a stop protrusion 219 at an end thereof away from the first rod body 211, the stop protrusion 219 abutting against the first abutting surface 121 to push the moving end 120 to move from the first position to the second position. In the second position, the stop protrusion 219 is spaced apart from the first abutting surface 121 in a predetermined direction. It can be understood that the stop protrusion 219 abuts against the first abutting surface 121 to push the moving end 120 to move from the first position to the second position under the driving of the driving assembly 230, and finally make the shell assembly 100 in the unfolded state. After the shell assembly 100 is unfolded to the position, under the driving of the driving assembly 230, the stop protrusion 219 moves away from the first abutting surface 121 to retreat a distance A, so that the stop protrusion 219 is spaced apart from the first abutting surface 121 and does not contact. In this way, when the electronic device 10 is impacted, the first abutting surface 121 will not be able to exert a second force Fb in the predetermined direction on the stop protrusion 219, thereby reducing the impact force on the push rod 210 in the predetermined direction, and also avoiding the push rod 210 directly pushing the driving assembly 230 under the action of the second force Fb and causing damage to the transmission member in the driving assembly 230 which transmits the movement of the push rod 210 in the predetermined direction, thereby protecting the driving assembly 230. In addition, the distance A of the retreat of the stop protrusion 219 does not need to be limited in range, as long as the moving end 120 can provide the required spacing.

[0055] Further, the moving end 120 has a second abutting surface 122, and the second abutting surface 122 is spaced apart from the first abutting surface 121 in the predetermined direction. The stop protrusion 219 is located between the first abutting surface 121 and the second abutting surface 122, and the distance between the first abutting surface 121 and the second abutting surface 122 is greater than the thickness of the stop protrusion 219 in the predetermined direction.

[0056] It should be noted that the distance between the first abutting surface 121 and the second abutting surface 122 refers to the minimum distance between a first point at any position on the first abutting surface 121 and a second point at any position on the second abutting surface 122. The thickness of the stop protrusion 219 in the predetermined direction refers to the maximum distance between any two points of the stop protrusion 219 in the predetermined direction. Since the distance between the first abutting surface 121 and the second abutting surface 122 is greater than the thickness of the stop protrusion 219 in the predetermined direction, during the movement of the moving end 120 driven by the stop protrusion 219, the stop protrusion 219 can only abut against one of the first abutting surface 121 and the second abutting surface 122, and can also provide a retreat space for the stop protrusion 219 after the moving end 120 is moved to the second position by the stop protrusion 219 abutting against the first abutting surface 121.

[0057] Specifically, in the embodiments of the present application, the stop protrusion 219 comprises a first stop surface 219a and a second stop surface 219b arranged in opposite directions. Specifically, the stop protrusion 219 acts on the moving end 120. In the process of unfolding the shell assembly 100, the first stop surface 219a acts on the moving end 120, and in the process of folding the shell assembly 100, the second stop surface 219b acts on the moving end 120. Further, in the process of unfolding the shell assembly 100, the first stop surface 219a abuts against the first abutting surface 121, and in the process of folding the shell assembly 100, the second stop surface 219b abuts against the second abutting surface 122.

[0058] In combination Figure 2 With Figure 3 As shown in the drawings, in the embodiments of the present application, the electronic device 10 comprises a buffer 300, which is arranged on the moving end 120 and has elasticity. When the second rod body 212 rotates relative to the first rod body 211 under the action of an external force, the second rod body 212 abuts against the buffer 300, and the buffer 300 exerts an elastic force on the second rod body 212 in a direction opposite to the rotation direction of the second rod body 212. When the electronic device 10 is impacted, the second rod body 212 will be subjected to a first force Fa in the vertical direction from the moving end 120, and will rotate in the first direction relative to the first rod body 211 under the action of the first force Fa. When the second rod body 212 contacts the buffer 300 and presses the buffer 300, the buffer 300 will exert a third force Fc on the second rod body 212 in the opposite direction, and the third force Fc will offset a part of the first force Fa in the vertical direction, thereby reducing the impact on the driving assembly 230 and avoiding damage to the locking member in the driving assembly 230 which constitutes a lock in the vertical direction to the push rod 210.

[0059] The moving end 120 has a first abutting surface 121 and a second abutting surface 122, and the second abutting surface 122 is arranged in a spaced relationship with the first abutting surface 121 in a predetermined direction. The second rod body 212 has a stop protrusion 219 at an end away from the first rod body 211, and the stop protrusion 219 is located between the first abutting surface 121 and the second abutting surface 122. The first abutting surface 121 and the second abutting surface 122 are each provided with a buffer 300 in the region therebetween. It can be understood that when the second rod body 212 rotates relative to the first rod body 211, the position of the second rod body 212 farthest away from the first rod body 211 (i.e. the position of the stop protrusion 219) has the largest deflection displacement. In addition, since the stop protrusion 219 moves in the region between the first abutting surface 121 and the second abutting surface 122, the buffers 300 are arranged in the range corresponding to the first abutting surface 121 and the second abutting surface 122, which will have a better buffering effect on the stop protrusion 219.

[0060] In particular embodiments, the buffer 300 is a silica gel pad. In other embodiments, the buffer 300 can also be configured as a spring or other type of elastic material such as foam.

[0061] Specifically, the end of the moving end 120 away from the fixed end 110 is provided with a first recess 123 extending from the first surface 124 of the moving end 120 to the inside of the moving end 120 along the thickness direction of the electronic device 10, and in the width direction, the two opposite inner walls of the first recess 123 form the first abutting surface 121 and the second abutting surface 122, respectively. The end of the moving end 120 away from the fixed end 110 is provided with a second recess 125 extending from the second surface 126 of the moving end 120 to the inside of the moving end 120 along the width direction of the electronic device 10, and the first recess 123 and the second recess 125 are in communication with each other inside the moving end 120. In this way, the stop protrusion 219 can extend into the second recess 125 through the first recess 123 and act on the first abutting surface 121 and the second abutting surface 122.

[0062] Further, the buffer 300 is arranged in the space communicated by the first recess 123 and the second recess 125. Specifically, in the thickness direction, the second recess 125 has a first side surface 125a and a second side surface 125b, and the upper surface 310 of the buffer 300 facing the first recess 123 corresponds to the region between the first side surface 125a and the second side surface 125b, so that the first side surface 125a and the upper surface 310 of the buffer 300 correspond to the opposite sides of the second rod body 212, respectively, so that the second rod body 212 moves in the gap between them in a predetermined direction. There is a gap between the second side surface 125b and the second rod body 212 to provide space for the second rod body 212 to rotate relative to the first rod body 211.

[0063] In combination Figure 1 With Figure 5As shown in the embodiments of the present application, the driving assembly 230 comprises a motor 231, a gearbox 232, a transmission screw rod 233, a screw nut 234 and a snap spring 235. The gearbox 232 is connected with the motor 231 to adjust the torque, the rotating speed and the rotating direction of the rotating motion output by the motor 231. The transmission screw rod 233 is connected with the gearbox 232 and rotates under the driving of the gearbox 232. The axial direction of the transmission screw rod 233 is set in a certain direction.
