An electronic device according to an embodiment of the present application is described below with reference to fig. 1 to 18.

As shown in connection with fig. 1, 2, 3, and 4, an electronic device according to some embodiments of the present application may be switched between a folded state and an unfolded state, wherein the folded state includes an folded-in state and a folded-out state. As shown in fig. 1, the electronic device is in an unfolded state, and the electronic device is in a large-screen display mode. As shown in fig. 2, the electronic device is in an folded state, and the flexible display screen 200 of the electronic device is external, so that the electronic device is in a small screen display mode. As shown in fig. 3, the electronic device is in an folded state, the flexible display screen 200 of the electronic device is built-in, and at this time, the occupied space of the electronic device is small, and the built-in mode of the flexible display screen 200 can also play a role in protecting the flexible display screen 200.

Referring to fig. 1 to 9, an electronic apparatus includes: a housing 100, a flexible display screen 200, and a transmission assembly 300. The housing has a receiving space and an opening 140. The opening 140 communicates with the receiving space 130. The first end a of the flexible display screen is fixed to the housing. The second end b of the flexible display screen extends into the receiving space 130 through the opening 140. The transmission assembly is mounted in the receiving space 130. The transmission assembly 300 includes a spool 310. The second end of the flexible display screen 200 extends into the receiving space 130 and is connected to the reel 310. The reel 310 rotates to move the second end of the flexible display screen 200. The transmission assembly 300 also includes a transmission 320. The transmission member 320 is rotatably coupled to the spool 310. The transmission member 320 may drive the rotation of the reel 310. The reel 310, when rotated, moves the second end of the flexible display screen 200 such that the second end of the flexible display screen 200 can move relative to the opening 140.

When the electronic device is in the unfolded state, the flexible display screen 200 is flattened. When the electronic device is in the folded-in state or the folded-out state, the flexible display screen 200 is folded.

The reel 310 is capable of unwinding a portion of the flexible display 200 proximate the second end b of the flexible display when rotated. As shown in fig. 9, the flexible display 200 has a winding portion on the left side, which is illustrated in the view. The reel 310 is capable of winding and unwinding the winding portion. As the reel 310 rotates counterclockwise, a portion of the flexible display 200 near the second end b of the flexible display is gradually wound around the reel 310. At this time, the contact area of the flexible display screen 200 with the reel 310 increases, and the display area of the flexible display screen 200 protruding out of the opening 140 decreases. As the reel 310 rotates clockwise, a portion of the flexible display screen 200 near the second end b of the flexible display screen gradually separates from the reel 310. At this time, the contact area of the flexible display screen 200 with the reel 310 decreases, and the display area of the flexible display screen 200 protruding out of the opening 140 increases. In this way, when the electronic device is switched from the unfolded state to the folded state, the driving member 320 drives the reel 310 to rotate, and the reel 310 winds up a portion of the flexible display screen 200. When the electronic device is switched from the unfolded state to the folded state, the driving member 320 drives the scroll 310 to rotate, and the flexible display screen 200 is gradually separated from the scroll 310.

As shown in fig. 11 and 12, in practical application, when the electronic device is switched from the unfolded state to the folded state, the transmission member 320 drives the scroll 310 to rotate along the first direction, so that a portion of the flexible display screen 200 is separated from the scroll 310, and the display area of the flexible display screen 200 located outside the opening 140 is increased. Compared with the mode that the display area of the flexible display screen outside the shell 100 is always unchanged in the related art, in the embodiment, the display area of the flexible display screen 200 in the outwards folded state is increased, so that local stress of the flexible display screen 200 in the outwards folded state is avoided, crease is not easy to occur on the flexible display screen 200, the damage rate of the flexible display screen 200 can be reduced, the service life of the scroll screen is prolonged, and the use experience of a user to electronic equipment is improved.

As shown in fig. 13 and 14, when the electronic device is switched from the folded-out state to the unfolded state, the transmission member 320 drives the reel 310 to rotate along the second direction, so that a portion of the flexible display screen 200 is wound on the reel 310. The area of the flexible display screen 200 outside the opening 140 is reduced, so that the problem that the flexible display screen 200 is stacked and arched at the bendable part is avoided, the display surface of the flexible display screen 200 can be kept flat all the time, and the use hand feeling of a user on the electronic equipment is ensured.

Similarly, when the electronic device is switched from the unfolded state to the folded state, the transmission member 320 continuously drives the reel 310 to rotate along the second direction, the reel 310 continuously winds the flexible display screen 200, and the display area of the flexible display screen 200 extending out of the opening 140 is reduced. The problem of stacking of the flexible display screen 200 in the folded-in state is avoided.

When the electronic equipment is switched from the folded-in state to the unfolded state, the transmission piece 320 drives the scroll 310 to rotate along the first direction, the flexible display screen 200 is gradually separated from the scroll, the display area of the flexible display screen 200 outside the opening 140 is increased, local stress of the flexible display screen 200 in the unfolded state is avoided, crease of the flexible display screen 200 is avoided, and the damage rate of the flexible display screen 200 is reduced.

In one possible application, in the folded-in state, the flexible display screen 200 has a contact area M1 with the reel 310. In the unfolded state, the contact area between the flexible display screen 200 and the reel 310 is M2, and in the folded state, the contact area between the flexible display screen 200 and the reel 310 is M3, which satisfies the following conditions: m3 > M2 > M1.

One of the first direction and the second direction is clockwise and the other is counterclockwise.

A reel 310 and a transmission member 320 are provided between the flexible display screen 200 and the elastic member 330, and the reel 310 and the transmission member 320 play a role in buffering the traction force exerted on the flexible display screen 200 by the elastic member 330. The problem that the flexible display screen 200 is damaged due to the fact that the flexible display screen 200 and the elastic piece 330 are directly connected is avoided. In addition, along the width direction of the flexible display screen 200, the contact area between the flexible display screen 200 and the reel 310 is larger, so that when the reel 310 drives the second end of the flexible display screen 200 to move, the connection stability of the flexible display screen 200 and the reel 310 can be ensured, and the possibility that the flexible display screen 200 and the reel 310 are separated is reduced. Moreover, due to the large contact area between the flexible display screen 200 and the reel 310, the second end of the flexible display screen 200 is uniformly stressed, so that the flexible display screen 200 is not easily damaged due to single-point stress.

The number of the driving members 320 may be one or at least two, and when the number of the driving members 320 is one, the driving members 320 may be disposed at the middle of the case 100 in order to secure the driving stability. When the number of the transmission members 320 is two, the two transmission members 320 are positioned at two sides of the housing 100, so as to ensure the stress balance of the scroll 310.

In practical application, the opposite sides of the housing 100 are provided with mounting holes 160, and two ends of the reel 310 extend into the mounting holes 160, so as to realize rotatable connection between the reel 310 and the housing 100. In order to secure rotational stability of the rotation shaft 310, a bearing (not shown) may be provided in the mounting hole 160, and an end of the rotation shaft 310 is assembled with the bearing.

As shown in connection with fig. 9, 10, 11 and 12, in this embodiment, the transmission assembly 300 further includes an elastic member 330. The first end of the elastic member 330 is disposed on the housing 100. The second end of the elastic member 330 is disposed on the transmission member 320. In the folded-in state of the electronic device, the elastic member 330 is in the original state. The original state of the elastic member 330 includes an undeformed state and a deformed state. In other words, when the elastic member 330 is in the original state, the traction force of the elastic member 330 applied to the transmission member 320 may be zero or non-zero. In the expanded state, the elastic member 330 is in a first elastically deformed state. In the folded-out state, the elastic member 330 is in a second elastic deformation state. Wherein, the deformation of the elastic member 330 in the first elastic deformation state is smaller than the deformation of the elastic member in the second elastic deformation state.

In practical application, when the electronic device is in the unfolded state, the elastic member 330 is in the first elastic deformation state. When the electronic device is switched from the unfolded state to the folded state, the deformed elastic piece 330 can pull the transmission piece, so that the transmission piece 320 drives the scroll 310 to rotate along the second direction, the scroll 310 can wind the flexible display screen 200, and the problem that the flexible display screen 200 is stacked is avoided. When the electronic device is switched from the folded state to the unfolded state, the flexible display screen 200 is gradually separated from the reel, the reel 310 rotates along the first direction, and the reel 310 pulls the elastic member through the transmission member 320, so that the elastic member is switched to the first elastic deformation state.

As shown in fig. 13, 14, 15 and 16, when the electronic device is switched from the unfolded state to the folded state, the flexible display screen 200 is gradually separated from the reel 310, the reel 310 rotates in the first direction, and the reel 310 pulls the elastic member 330 through the transmission member 320, so that the elastic member 330 is switched from the first elastic deformation state to the second elastic deformation state. Since the deformation amount of the elastic member 330 in the second elastic deformation state is greater than the deformation amount of the elastic member 330 in the first elastic deformation state, the elastic member 330 is further stretched when the electronic device is switched from the unfolded state to the folded state.

Referring to fig. 14 and 15, when the electronic device is switched from the folded state to the unfolded state, the elastic member 330 is switched from the second elastic deformation state to the first elastic deformation state, the reel 310 rotates along the second direction, and a portion of the flexible display screen 200 is gradually wound around the reel 310, so as to avoid the problem of stacking the flexible display screen 200.

In this embodiment, the transmission member 320 and the reel 310 are disposed between the elastic member 330 and the flexible display screen 200, which can effectively reduce the damage rate of the flexible display screen 200 compared with the manner in which the elastic member 330 is directly connected with the flexible display screen 200.

The speed of separation of flexible display 200 from spool 310 is related to the speed of folding and unfolding of the electronic device. The separation of the flexible display screen 200 and the reel 310 and the folding or unfolding process of the electronic device are performed synchronously, so that the problem that the flexible display screen 200 is suddenly stretched due to the fast folding or unfolding speed of the electronic device can be avoided, the damage rate of the flexible display screen 200 is reduced, and the user experience is improved.

Likewise, the speed at which flexible display screen 200 is wound onto reel 310 is related to the folding and unfolding speed of the electronic device. I.e. the process of winding the flexible display screen 200 around the reel 310 and the folding or unfolding process of the electronic device are performed simultaneously, avoiding the problem of stacking the flexible display screen 200.

In other embodiments, the transmission assembly 300 may include a motor that rotates the spool 310 via the transmission 320.

In this embodiment, the transmission member 320 and the reel 310 are respectively provided with mutually matched engagement teeth; the transmission member 320 is elastically coupled to the housing 100 around the reel 310.

The transmission piece 320 can be a transmission belt, the transmission belt winds around the scroll, and meshing teeth are arranged between the transmission belt and the scroll, so that the transmission stability of the transmission piece 320 and the scroll 310 can be ensured, and the problem of slipping between the transmission piece 320 and the scroll 310 is not easy to occur.

Specifically, the transmission member 320 is provided with a first engagement tooth 321. Spool 310 includes a shaft 312 and a gear 313. A second end of flexible display screen 200 is secured to shaft 312. The gear 313 is provided on the shaft 312. Gear 313 is provided with a first engagement tooth 321. The transmission member 320 is provided with a second engagement tooth 311 engaged with the first engagement tooth 321. The transmission member 320 is elastically coupled to the housing 100 around the gear 313. The first engagement tooth 321 engages with the second engagement tooth 311.

The transmission member 320 and the shaft body 312 are transmitted in a meshing manner, so that the rotation of the transmission member 320 and the rotation of the scroll 310 are synchronously performed, thereby being beneficial to improving the synchronism of the movement of the shell 100 and the movement of the scroll 310, avoiding the problem that the flexible display screen 200 is stacked or stretched, and being beneficial to improving the functional stability of the electronic equipment.

In practice, the number of gears 313 may be one or at least two. When the number of the gears 313 is at least two, at least two gears 313 are engaged with each other. The transmission member 320 bypasses one of the gears 313, and at least two gears 313 pass through the transmission member 320 to drive the reel 310 to rotate. By arranging at least two gears 313 between the transmission member 320 and the shaft body 312, the transmission ratio between the transmission member 320 and the shaft body 312 can be changed, so that the winding and unwinding speed of the reel 310 to the flexible display screen 200 can be adjusted, the problem that the flexible display screen 200 is stacked or stretched is avoided, and the functional stability of the electronic equipment is improved.

The number of sets of gears 313 and the size of each gear 313 in the set of gears 313 can be adjusted according to actual needs.

As shown in fig. 10, in the present embodiment, a mounting groove 3121 is provided on the shaft body 312. The second end of the flexible display screen 200 is inserted and fixed in the mounting groove 3121. The mounting groove 3121 plays a role in clamping and fixing the flexible display screen 200, so that the flexible display screen 200 and the reel are not easily separated, and a function of mounting and fixing the flexible display screen 200 is realized. In practical applications, the width of the mounting groove 3121 should be smaller than the width of the flexible display screen 200, and the interference fit between the two ensures that the flexible display screen 200 can be clamped in the mounting groove 3121, so as to avoid the flexible display screen 200 and the reel 310 from being separated.

In other embodiments, it is also possible to provide that the second end of the flexible display screen 200 is secured to the shaft 312 by a locking member. The locking piece can be a lock catch or a clamping structure, the lock catch or the clamping structure can lock the flexible display screen 200 on the scroll 310, compared with a mode of plugging the flexible display screen 200 in the mounting groove 3121, in order to avoid bending of the flexible display screen 200 in the mounting groove 3121, the flexible display screen 200 is fixed through the lock catch or the clamping structure, and the damage rate of the flexible display screen 200 can be reduced.

As shown in conjunction with fig. 6, 7, 8 and 11, in the present embodiment, the housing 100 includes a first body 110 and a second body. The accommodating space 130 is disposed in the first body 110. The second body 120 is rotatably connected to the first body 110. The first end of the transmission member 320 is disposed on the second body 120. The transmission member 320 is elastically coupled to the first body 110.

The first body 110 and the second body 120 are rotatably connected. When the electronic device is in the unfolded state, the first body 110 and the second body 120 are flattened. When the electronic device is in the folded state, the first body 110 and the second body 120 are folded.

In practical applications, the housing 100 further includes a shaft 600 and a sleeve 700. The rotating shaft 600 is disposed on the first body 110. The sleeve 700 is disposed on the second body 120. The shaft sleeve 700 is sleeved on the rotating shaft 600.

The rotation shaft 600 is fixed to the first body 110. The sleeve 700 is fixed to the second body 120. The shaft sleeve 700 is sleeved on the rotating shaft 600. The shaft sleeve 700 is coaxially disposed with the rotation shaft 600 such that the shaft sleeve 700 can rotate with respect to the rotation shaft 600. By providing the rotation shaft 600 and the shaft sleeve 700 between the first body 110 and the second body 120, a function that the first body 110 and the second body 120 can rotate is achieved. The contact area between the rotation shaft 600 and the shaft sleeve 700 is large, and the stability of the first body 110 and the second body 120 during the relative rotation can be effectively improved.

As shown in connection with fig. 4 and 5, in one possible embodiment, the number of shafts 600 and bushings 700 is two. Along the axial direction of the rotating shafts 600, two rotating shafts 600 are disposed at intervals. The two bushings 700 are spaced apart accordingly.

In this embodiment, the number of the rotation shaft 600 and the shaft sleeve 700 is defined as two. Two rotating shafts 600 and shaft sleeves 700 are provided at both sides of the case 100. Compared with the arrangement of the rotating shaft 600 and the shaft sleeve 700 which have the same width as the housing 100, the arrangement of the rotating shaft 600 and the shaft sleeve 700 which are arranged at intervals can reduce the material consumption and save the processing cost. Moreover, through reducing the material consumption, can effectively reduce electronic equipment's weight, realize electronic equipment's lightweight, the user is laborsaving to electronic equipment's use more, is favorable to improving user's convenience to electronic equipment. Along the width direction of the casing 100, the distances from the two rotating shafts 600 to the central line of the casing 100 are basically the same, and the two shaft sleeves 700 are similar, so that the first body 110 and the second body 120 are balanced in stress during rotation, the problem that the first body 110 and the second body 120 are blocked during rotation is avoided, and the use experience of a user on electronic equipment is improved.

As shown in connection with fig. 17 and 18, in this embodiment, the transmission assembly 300 further includes a connector 400. The second body 120 is provided with a connection hole 121. The connection member 400 is inserted into the connection hole 121. The first end of the transmission member 320 is fixed to the second body 120 through the connection member 400.

The connecting piece 400 fixes the transmission piece 320 on the second body 120, so as to avoid the separation of the transmission piece 320 and the second body 120, and facilitate improving the functional stability of the electronic device.

In practice, the connector 400 is a pin, which is inserted into the connecting hole 121. A portion of the transmission member 320 also extends into the second body 120. The second body 120 is provided with a plugging portion into which the transmission member 320 extends. And the transmission member 320 extending into the second body 120 passes through the connection hole 121. Inserting the transmission member 320 into the insertion portion can bend a portion of the transmission member 320, which is beneficial to improving the contact area between the transmission member 320 and the second body 120, increasing the friction force between the transmission member 320 and the second body 120, and further improving the connection stability between the transmission member 320 and the second body 120. In the present embodiment, the plugging portion is a plugging hole 122 formed on the second body 120, and the plugging hole 122 is communicated with the connecting hole 121.

In this embodiment, the electronic device further includes a positioning member 500. The positioning member 500 is disposed on the first body 110. The transmission member 320 is located between the positioning member 500 and the first body 110.

The positioning member 500 can provide a limiting function to the transmission member 320. In the process of switching the electronic device, the positioning member 500 limits the transmission member 320 on the first body 110, so as to avoid the loosening phenomenon of the transmission member 320, and ensure that the transmission member 320 can stably drive the reel 310 to rotate.

In practical application, the positioning member 500 is formed with a limiting hole. The driving member passes through the limiting hole on the positioning member 500.

In the present embodiment, the housing 100 is provided with a bearing portion 150. The bearing portion 150 is provided with a bearing surface 151 and a mounting surface 152. The bearing surface 151 and the mounting surface 152 are opposite surfaces on the bearing 150. The flexible display 200 is attached to the carrying surface 151. The positioning member 500 is disposed between both ends of the transmission member 320. The positioning member 500 aligns at least a portion of the actuator 320 with the mounting surface 152.

The bearing surface 151 bears the flexible display screen 200. When the user presses the flexible display screen 200, the flexible display screen 200 is not easy to dent, which is beneficial to improving the use experience of the user. The limiting action of the positioning member 500 on the transmission member 320 makes at least a portion of the transmission member 320 parallel to the mounting surface 152, so as to avoid loosening of the transmission member 320, and further improve the uniformity inside the housing 100.

In this embodiment, when the electronic device is in the unfolded state, the edge of the opening 140 is aligned with the initial position H of the flexible display screen 200. When the electronic device is in the folded state, the initial position is located inside the accommodating space 130. When the electronic device is in the folded-out state, the initial position is located outside the accommodating space 130.

When the electronic device is in the unfolded state, a position of the edge of the opening 140 opposite to the flexible display screen 200 is used as a reference position, i.e., an initial position H. When the electronic device is switched from the unfolded state to the folded state, the initial position H is located in the accommodating space 130, that is, the initial position H moves into the accommodating space 130, which indicates that a portion of the flexible display screen 200 is wound around the reel. When the electronic device is switched from the unfolded state to the folded state, the initial position H is located outside the accommodating space 130, that is, the initial position H moves outside the accommodating space 130, which indicates that a portion of the flexible display screen 200 extends out of the accommodating space, so as to avoid the flexible display screen 200 from generating folds.

In the above embodiment, the electronic device may be one of a mobile phone, a tablet computer, and a folding notebook.
