Referring to fig. 1, 2 and 3, an electronic device 10 is provided. The electronic device 10 of the present embodiment includes a housing 12, a flexible display 14, a resilient element 16, and an actuator 18.

A flexible display 14 is positioned on the housing 12 and is slidable relative to the housing 12. Elastic element 16 is positioned between housing 12 and flexible display 14 and is configured to generate a first force F1 that flattens flexible display 14. An actuator 18 is connected to the resilient element 16, the actuator 18 being adapted to generate a second force F2 opposite to the first force F1, the second force F2 being less than or equal to the first force F1.

The electronic device 10 of the embodiment of the application, which generates the second acting force F2 opposite to the first acting force F1 by using the actuator 18, alleviates or even avoids the flexible display 14 from being stretched and deformed, and is beneficial to protecting the flexible display 14 and improving the aesthetic appearance of the electronic device 10.

Notably, "flat" means that the flexible display 14 fits completely over the housing 12 of the electronic device 10 without warping, such as arching.

It will be appreciated that the bending angle (0 ° -360 °) of the flexible display 14 is in one-to-one correspondence with the first force F1, so that when the first force F1 is determined, the bending angle of the flexible display 14 is already determined, and thus the appropriate force that the flexible display 14 can withstand at the bending angle is determined. The appropriate force is the difference between the first force F1 and the second force F2. In this way, the second force F2 can be flexibly controlled to control the appropriate force to which the flexible display 14 is subjected, thereby preventing the flexible display 14 from being damaged.

In some embodiments, the electronic device 100 has a fully bent state, a transitional state, and a fully flattened state; the actuator 18 is configured to generate a second force F2 opposite the first force F1 when the flexible display screen 14 is in the fully flexed state and/or the fully flattened state.

Note that the actuator 18 may generate a second force F2 opposite the first force F1 when the flexible display 14 is in a transition state between fully flexed and fully extended states. The time during which the second force F2 is generated is not limited herein.

In the above embodiment, since the distance between the contact point of the flexible display 14 and the elastic element 16 and the contact point of the housing 12 and the elastic element 16 changes with time during the process of bending the flexible display 14, the distance between F1 and the contact points is positively correlated, i.e. the larger the distance between the contact points is, the larger F1 is. Ideally, however, the amount of tension experienced by the flexible display 14 should be minimal given that it is flat. The reason for this is that on the one hand the flexible display 14 should be flat to provide a smooth and wrinkle-free display surface for the user, and on the other hand the less force it is subjected to is better in order to minimize damage to the structure of the flexible display 14. Based on the above, the present application generates the second force F2 opposite to F1 by the actuator, so as to stress the flexible display 14 to satisfy the above condition, thereby enabling the flexible display 14 to be unfolded and simultaneously subjected to the appropriate force.

In one example, the flexible display 14 is in a fully-stretched state, the actuator 18 generates a second force F2 opposite to the first force F1, the second force F2 is equal to the first force F1, and the flexible display 14 is balanced in the direction of the first force F1 by the actuator 18, which is equivalent to eliminating the first force F1 of the elastic element 16 to which the flexible display 14 is subjected.

In another example, the flexible display 14 is in a fully flexed state, the actuator 18 generates a second force F2 opposite to the first force F1, the second force F2 is equal to the first force F1, and the flexible display 14 is balanced in the direction of the first force F1 by the actuator 18, which is equivalent to eliminating the first force F1 of the elastic element 16 to which the flexible display 14 is subjected.

In yet another example, with the flexible display 14 in a fully flattened state, the actuator 18 generates a second force F2 opposite the first force F1, the second force F2 is less than the first force F1, and the flexible display 14 is subjected to an appropriate force in the direction of the first force F1 by the actuator 18, the appropriate force being the difference between the first force F1 and the second force F2.

Referring also to fig. 4, in some embodiments, the actuator 18 includes a first magnetic component 182 and a second magnetic component 184, and the repulsive force of the first magnetic component 182 and the second magnetic component 184 forms a second force F2.

In this manner, the second force F2 generated by the actuator 18 is achieved.

In some embodiments, the first magnetic member 182 is fixedly connected between the housing 12 and the elastic member 16, and the second magnetic member 184 is fixedly connected between the flexible display 14 and the elastic member 16.

In this manner, the flexible display 14 is subjected to a second force F2. It is understood that since the first magnetic member 182 is fixedly connected to the housing 12 and the second magnetic member 184 is connected to the flexible display 14, when the second magnetic member 184 receives the magnetic force applied by the first magnetic member 182, the flexible display 14 receives the second force F2 applied by the second magnetic member 184.

In certain embodiments, the first magnetic component 182 and/or the second magnetic component 184 are electromagnetic elements.

In this way, the first magnetic member 182 and the second magnetic member 184 cooperate to generate a magnetic force as the second acting force F2. Specifically, in one example, the first magnetic component 182 is an electromagnetic element and the second magnetic component 184 is a permanent magnetic element. In another example, the second magnetic component 184 is an electromagnetic element and the first magnetic component 182 is a permanent magnetic element. In yet another example, the first magnetic component 182 is an electromagnetic component and the second magnetic component 184 is an electromagnetic component.

Additionally, in other embodiments, the actuator 18 may be a piezo-electric drive.

In particular, the piezoelectric drive mechanism is based on the inverse piezoelectric effect of piezoelectric ceramic materials. If voltage is applied to the piezoelectric material, mechanical stress is generated, namely, the electric energy and the mechanical energy are converted, and the rotation or linear motion is generated by controlling the mechanical deformation of the piezoelectric material, so that the piezoelectric material has the advantages of simple structure and low speed.

In some embodiments, the electronic device 10 includes a sensor 11 and a processor 13, the sensor 11 is connected to the flexible display 14 and is configured to acquire the first force F1, and the processor 13 is configured to control the actuator 18 to generate the second force F2 according to the first force F1 acquired by the sensor 11.

In this way, the acquisition of a specific value of the first force F1 and the control of the second force F2 are achieved. Specifically, the sensor 11 sends the collected value of the first acting force F1 to the processor 13 after detecting the first acting force F1 applied to the flexible display 14, and the processor 13 determines the value of the second acting force F2 after receiving the value of the first acting force F1 and controls the actuator 18 according to the value of the second acting force F2, so that the actuator 18 generates the second acting force F2 with the value.

In some embodiments, the electronic device 10 includes a sensor 11 and a processor 13, the sensor 11 is connected to the flexible display 14 and is configured to acquire the first force F1, and the processor 13 is configured to control the magnetism of the first magnetic member 182 and/or the second magnetic member 184 according to the first force F1 acquired by the sensor 11, so as to control the repulsive force between the first magnetic member 182 and the second magnetic member 184.

In this way, the acquisition of a specific value of the first force F1 and the control of the second force F2 are achieved. Specifically, after detecting the first acting force F1 applied to the flexible display 14, the sensor 11 sends the collected value of the first acting force F1 to the processor 13, and after receiving the value of the first acting force F1, the processor 13 determines the value of the second acting force F2, and controls the first magnetic member 182 and the second magnetic member 184 according to the value of the second acting force F2, so that the first magnetic member 182 and the second magnetic member 184 generate the second acting force F2 of the value.

More specifically, when at least one of the first magnetic component 182 and the second magnetic component 184 is an electromagnetic element, the processor 13 may control the magnitude of the magnetic force received by the second magnetic component 184 from the first magnetic component 182 by controlling the magnitude of the current, thereby controlling the magnitude of the second force F2.

In addition, the sensor 11 may be a tension sensor. In this embodiment, the sensor 11 is connected to the second magnetic component 184, or the sensor 11 is disposed close to the flexible display 14, so that the sensor 11 can more accurately acquire the pulling force applied to the flexible display 14.

In some embodiments, the housing 12 is provided with a guide structure 122 extending along the relatively movable direction of the flexible display 14, and the flexible display 14 is connected with a sliding slot structure 123 sliding along the guide structure 122.

In this way, the movement of the flexible display 14 is made more stable. It will be appreciated that the flexible display 14 is likely to deviate from the predetermined trajectory and even fall off the electronic device 10 due to the external force during the movement. By providing the guide structure 122, the moving track of the flexible display 14 can be ensured.

In some embodiments, the actuator 18 includes a first magnetic component 182 and a second magnetic component 184, the repulsive force of the first magnetic component 182 and the second magnetic component 184 forms a second force F2, and the chute structure 123 includes the second magnetic component 184.

In this way, the sliding of the second magnetic member 184 is made more stable. It can be understood that the second magnetic member 184 is likely to deviate from the predetermined track or even fall off the electronic device 10 due to the external force during the sliding process. By providing the guide structure 122, the sliding track of the second magnetic member 184 can be ensured, so as to ensure that the second acting force F2 exerted by the second magnetic member 184 on the flexible display 14 is consistent with the direction of the first acting force F1 in direction, and further ensure that the second acting force F2 exactly fully or partially counteracts the first acting force F1.

Note that the "relative movable direction of the flexible display 14" here is the Y direction and the-Y direction in fig. 4.

In some embodiments, the guide structure 122 includes a slide rail 1222, the sliding slot structure 123 is formed with a sliding slot 1842 engaged with the slide rail 1222, and the sliding slot structure 123 is disposed on the slide rail 1222 through the sliding slot 1842.

In this manner, the arrangement of the guide structure 122 is achieved. Specifically, the sliding groove 1842 may be disposed at the bottom of the sliding groove structure 123, and the surface roughness of the sliding groove 1842 and the sliding rail 1222 may be used to control the friction force when the sliding groove structure 123 slides on the sliding rail 1222.

Of course, in other embodiments, the guiding structure 122 may include a sliding groove, the sliding groove structure 123 is formed with a sliding rail cooperating with the sliding groove, and the sliding groove structure 123 is disposed on the sliding groove through the sliding rail.

In some embodiments, the electronic device 10 includes at least two guide structures 122; the electronic device 10 is configured with at least two elastic elements 16 and at least two actuators 18 for at least two guiding structures 122; the flexible display 14 includes at least two sliding slot structures 123 that slide along the at least two guiding structures 122, respectively.

In this way, the flattening of the flexible display 14 can be made more stable. In the example shown in fig. 4, the electronic device 10 includes two guiding structures 122, two elastic elements 16 and two actuators 18, the flexible display 14 includes two sliding slot structures 123, and two guiding structures 122, two elastic elements 16, two actuators 18 and two sliding slot structures 123 are symmetrical with respect to a central axis of a relative moving direction of the flexible display 14.

Of course, in other embodiments, the number of the elastic elements 16 may be one, three, four, etc. or any other number, and the number of the actuators 18, the guide structures 122, and the sliding groove structures 123 may correspond to the number of the elastic elements 16.

In some embodiments, the planar shape of the flexible display 14 is rectangular, and in the relatively movable direction of the flexible display 14, the flexible display 14 includes a first end 142 and a second end 144 opposite to each other, the first end 142 is fixedly connected to the housing 12, the second end 144 is movable relative to the housing 12, and the elastic element 16 is connected to the second end 144.

In this way, the flexible display 14 is not damaged when the electronic device 10 is switched between the bent state and the unfolded state. Specifically, in one example, when the electronic device 10 is in the bent state, the elastic element 16 is in a stretched state, and when the electronic device 10 is converted from the bent state to the flat state, the stretching degree of the elastic element 16 is gradually reduced, that is, the second end 144 of the flexible display 14 is closer to the housing 12 in the relatively movable direction of the flexible display 14.

In certain embodiments, the resilient element 16 comprises a spring.

A spring is a mechanical part that works by elasticity and is generally made of spring steel. The principle is that a part made of elastic material deforms under the action of external force, and recovers to the original shape after the external force is removed, so that the size change of the flexible display screen 14 can be well adjusted. The spring is common and easy to obtain, has a pure and mature manufacturing process and is simple and convenient to use, and is a good elastic element.

More, the sliding of the flexible display 14 relative to the housing 12 can be affected by selecting different springs to obtain different elastic forces, for example, the larger the elastic force of the spring, the more powerful the sliding of the flexible display 14 relative to the housing 12 is; the less the spring force of the spring, the more gradual the sliding of the flexible display 14 relative to the housing 12. Of course, the elastic element 16 may be a hydraulic cylinder, a rubber element, or the like having a damping function.

In certain embodiments, the housing 12 includes a floor 124, sidewalls 126, and a cover 128. The side walls 126 extend upward from the edges of the bottom plate 124. A cover portion 128 extends from an end of the side wall 126 remote from the base plate 124. The side wall 126 surrounds the flexible display 14. The covering portion 128, the side walls 126 and the bottom plate 124 enclose a receiving space 129, and the elastic element 16 and the actuator 18 are located in the receiving space 129.

Specifically, in the electronic device 10, the housing 12 is an external structure of the electronic device 10, and the bottom plate 124, the covering portion 128 and the side wall 126 may cooperate with each other to form a receiving space 129 for shielding the elastic element 16 and the actuator 18, which may make the electronic device 100 more attractive.

Furthermore, the housing 12 can be made of a flexible material such as a polymer to meet the requirement of bending deformation of the electronic device 10, and the production cost can be reduced.

Referring to fig. 5 and 6, a protrusion 1242 is formed at a middle portion of the bottom plate 124, a first groove 1262 and a second groove 1264 are formed between the protrusion 1242 and the side wall 126, and the first groove 1262 and the second groove 1264 are spaced apart from each other. The electronic device 100 includes a first stiffener 15 and a second stiffener 17, and the first stiffener 15 is received in the first groove 1262 and attached to the flexible display 14 through the first adhesive layer 151. The second reinforcing plate 17 is accommodated in the second groove 1264 and attached to the flexible display screen 14 through the second adhesive layer 171, and the housing 12 can be bent at the protrusion 1242. The protrusion 1242 corresponds to the bending region 141 of the flexible display 14.

The protrusion 1242 is a platform protruding from the housing 12 toward the flexible display screen 14, and the first groove 1262 and the second groove 1264 facilitate the arrangement of the rest parts of the subsequent flexible display screen 14, thereby improving the space utilization rate of the housing 12 and the flexible display screen 14 and the stability of connection therebetween.

The first reinforcing plate 15 is accommodated in the first groove 1262, it can be understood that there is a certain friction between the first reinforcing plate 15 and the bottom plate 124, and since the first reinforcing plate 15 and the electronic device 10 are fixedly arranged, in the process of bending the electronic device 10, the mutual friction between the first reinforcing plate 15 and the bottom plate 124 can make the flexible display screen 14 and the bottom plate 124 relatively fixed in position relation, thereby preventing the two ends of the flexible display screen 14 from simultaneously displacing when bending, and making the bending process of the flexible display screen 14 easy to control. Further, the magnitude of the frictional force can be controlled by setting the surface roughness of the first reinforcing plate 15 and the base plate 124.

In some embodiments, the housing 12 includes an elastic piece 19 fixed on the protrusion 1242, the elastic piece 19 is configured to bend along with the bending of the housing 12, the elastic piece 19 is located between the first reinforcing plate 15 and the second reinforcing plate 17, and the first reinforcing plate 15 and the second reinforcing plate 17 are both spaced apart from the elastic piece 19.

The elastic piece 19 bends along with the bending of the housing 12, and can provide a shaping force for maintaining the housing 12 in a bent state after bending and a restoring power when the housing 12 is converted from bending to flattening, so that the bending and flattening of the housing 12 are normally switched. The flexible sheet 19 may also be used to maintain relative flatness between the flexible display 14 and the housing 12 and provide support for the flexible display 14, thereby placing the flexible sheet 19 on the relatively flat protrusion 1242.

The first reinforcing plate 15 and the second reinforcing plate 17 are both spaced from the elastic sheet 19, that is, there are variable distances and spaces between the first reinforcing plate 15, the second reinforcing plate 17 and the protrusion 1242, and when the flexible display 14, the housing 12 and the electronic device 10 are bent, the size change of the bent portion of the flexible display 14 is adjusted by the variation of the distances between the first reinforcing plate 15, the second reinforcing plate 17 and the protrusion 1242.

It can be understood that the first reinforcing plate 15, the second reinforcing plate 17 and the elastic sheet 19 are substantially plate-shaped, the plate-shaped structure is regular, the manufacturing and molding are convenient, the corresponding structural position is easy to set, and the regular and regular electronic device 10 can be formed.

In some embodiments, the bending angle of the electronic device 10 is 0-180 degrees, and when the bending angle is 180 degrees, the first reinforcing plate 15 and the second reinforcing plate 17 are stacked.

It is understood that the bending angle of the electronic device 10 is equivalent to the bending angle of the flexible display 14. When the bending angle of the electronic device 10 is 0 degree, the electronic device is in a flat state, the flexible display screen 14 is flat, so that the electronic device 10 has a good display effect, and at the moment, the first reinforcing plate 15, the second reinforcing plate 17 and the elastic sheet are also in a flat state and are approximately positioned on the same plane; when the bending angle of the electronic device 10 is 180 degrees, the electronic device 10 and the flexible display screen 14 are folded, so that the space occupation of the electronic device 10 is reduced, and the electronic device can be better stored and carried.

Referring to fig. 7, in some embodiments, the electronic device 10 includes a cover 143, and the cover 143 is disposed on the flexible display 14.

Specifically, in the electronic device 10, the flexible display 14 is used for displaying images and pictures, and the cover plate 143 is disposed on the flexible display 14, so that the flexible display 14 and the internal structure thereof can be effectively protected, and the flexible display 14 and the internal structure thereof are prevented from being damaged by external acting force.

Referring to fig. 8, in some embodiments, the flexible display 14 may include a touch layer 146, a display layer 147, a polarizer 148 and a flexible substrate 149, which are sequentially stacked, and the cover 143 covers the touch layer 146.

Specifically, the cover 143, the touch layer 146, the display layer 147, and the polarizer 148 may be made of flexible materials. In addition, the transmittance of the cover plate 143 and the touch layer 146 to visible light is greater than 90%, which is beneficial for the display layer 147 to better show the content effect. The touch layer 146 is mainly used for receiving an input signal generated when a user touches the touch layer 146 and transmitting the input signal to the processor 13 for data processing, so as to obtain a specific position where the user touches the touch layer 146. In-Cell or On-Cell technology can be adopted to combine the touch layer 146 and the display layer 147, so that the weight of the display layer 147 can be effectively reduced and the overall thickness of the display layer 147 can be reduced, so that the flexible display screen 14 is more compact and thinner. The polarizer 148 may ensure proper imaging and display of the flexible display 14 to ensure proper use of the electronic device 10.
