Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic view of a first state of a flexible display device according to an embodiment of the present invention. Fig. 2 is a schematic diagram of a second state of the flexible display device shown in fig. 1 according to an embodiment of the present invention. The flexible display device is suitable for vehicle interior decoration, such as display center control. Referring to fig. 1 and 2, the flexible display device 10 includes a first body 11 and a second body 12 connected by a distance adjustment assembly, a rotation shaft (not shown) covered by the second body 12, and a flexible display 13. The spindle is rotatably fixed to the second body 12. The flexible display 13 includes a fixed end a fixed on the first body 11 and a curled end B fixed on the rotation shaft. The flexible display device 10 comprises a first state and a second state. In the first state, the flexible display 13 has a first roll length on the rotation axis, and the first body 11 and the second body 12 have a first distance therebetween. In the second state, the flexible display 13 has a second curled length on the rotation axis, and the first body 11 and the second body 12 have a second distance therebetween. The first curl length is less than the second curl length and the first spacing is greater than the second spacing.
The first and second curled lengths refer to lengths of the flexible display 13 wound around the rotation shaft. The first curled length is smaller than the second curled length, and the first spacing is larger than the second spacing, i.e., as the curled length of the flexible display 13 increases, the spacing between the first body 11 and the second body 12 decreases.
The first body 11 is a first casing, the second body 12 is a second casing, and the first body 11 and the second body 12 form an integral frame of the flexible display device 10, and may be used to fix or accommodate other components such as the flexible display 13 and the rotation shaft. The flexible display 13 refers to a flexible and rollable display, such as a flexible organic light emitting diode display. Both ends of the rotation shaft are rotatably fixed on the second body 12, so that the rotation shaft can rotate with respect to the second body 12, thereby driving the flexible display 13 to gradually curl onto the rotation shaft through the curled end B thereof, or gradually disengage from the rotation shaft to unfold.
During the gradual rolling of the flexible display 13 onto the rotation shaft, the first body 11 and the second body 12 are brought close to each other by the distance adjustment assembly. The first body 11 and the second body 12 are moved away from each other by the distance adjusting assembly during the flexible display 14 is gradually separated from the rotation shaft 13 to be unfolded. The distance adjustment assembly may be a sliding assembly, for example a sliding fit, a track and a slider provided on the first body 11 and the second body 12, respectively. In this case, the first body 11 and the second body 12 are slidably spaced from each other. The distance adjustment assembly may also be a lifting assembly, such as a telescopic rod. In this case, the distance between the first body 11 and the second body 12 is adjusted by elevating.
According to the flexible display device provided by the embodiment, the flexible display screen is used for replacing a hard screen display screen, the distance between the first main body 11 and the second main body 12 is reduced along with the increase of the curling length of the flexible display screen 13, the contraction function of the flexible display device is realized, the use mode is more flexible, and the user experience satisfaction is improved.
In one embodiment, as shown in fig. 1 and 2, the first body 11 and the second body 12 are slidably coupled. When the flexible display device 10 is in the first state, as shown in fig. 1, the first body 11 and the second body 12 are away from each other, and the flexible display 13 is in a fully flattened state. When the flexible display device 10 is in the second state, as shown in fig. 2, the first body 11 and the second body 12 are close to each other, and the flexible display 13 is in a partially rolled and partially flattened state. In this case, when the flexible display device 10 is in the second state, a partial area of the flexible display screen 13 may be used as a sub-screen, for example, to display time.
Fig. 3 is a schematic diagram of a second state of the flexible display device shown in fig. 1 according to a second embodiment of the present invention. As shown in fig. 3, the flexible display device 20 provided according to the present embodiment is different from the flexible display devices shown in fig. 1 and 2 only in that when the flexible display device 10 is in the second state, the first body 11 and the second body 12 are close to each other, and the flexible display 13 is in a completely rolled state. In this case, when the flexible display device 10 is in the second state, a partial area of the first body 11 may lack a shield due to the curling of the flexible display 13, thereby forming a recess for receiving.
It should be understood that the first state of the flexible display device 10 as shown in fig. 1, and the second state of the flexible display device 10 as shown in fig. 2 and 3, are merely exemplary. In an actual product, any state of the flexible display device 10 in the distance adjustable range of the distance adjusting device can be taken as the first state and/or the second state, and accordingly, when the flexible display device 10 is in the first state and/or the second state, the specific form of the flexible display screen 13 can be set arbitrarily, for example, a part of the curled portion is flattened; or fully rolled, or fully flattened, etc., i.e., the specific configuration of the flexible display device 10 in the first and second states may differ depending on user selection or setting. The embodiment of the present invention does not limit the specific structure of the first state and the second state of the flexible display device 10.
The following describes the internal structure of the flexible display device in detail, taking the flexible display device shown in fig. 1 and 2 as an example.
Fig. 4 is a schematic diagram of an internal structure of the flexible display device shown in fig. 1 and 2 according to an embodiment of the present invention. As shown in fig. 4, in the present embodiment, the flexible display device 10 includes a lead screw 21 fixed to the first body 11 and a power device 22. The screw 21 and the power device 22 are connected through a first transmission assembly, and the screw 21 and the power device 22 are positioned on the same side of the first transmission assembly.
Specifically, the first body 11 and the second body 12 are slidably connected by a lead screw module. The screw 21 of the screw module is fixed to the first body 11, and the slider (hidden and not shown) of the screw module is fixed to the second body 12. The screw 21 is driven by a power device 22 fixed to the first body 11 driving a first transmission assembly, and the screw 21 and the power device 22 are located on the same side of the first transmission assembly.
In the present embodiment, as shown in fig. 4, the power unit 22 is a motor. The first transmission assembly comprises a first pulley 24 and a second pulley 25 connected by a first timing belt 23. The motor is coaxially fixed with the first pulley 24, and the screw 21 is coaxially fixed with the second pulley 25.
According to the flexible display device provided by the embodiment, the power provided by the power device 22 is transmitted to the lead screw 21 by using the first transmission assembly, so that the power device 22 and the lead screw 21 can be arranged on the same side of the first transmission assembly, and compared with the case that the power device 22 and the lead screw 21 are required to be coaxially arranged when the lead screw 21 is directly driven by using the power device 22, the flexible display device saves space and is beneficial to equipment miniaturization.
In other embodiments, the first body 11 and the second body 12 are slidably connected by mutually cooperating rails and sliders. For example, rails are provided on opposite sides of the first body 11, and two sliders are provided at corresponding positions of the second body 12 to be engaged with the rails. Further, a stopper may be further provided at the start end and/or the termination end of the track for maintaining the relative positions of the first body 11 and the second body 12 in the current state. In this case, the first body 11 and the second body 12 can be manually driven to slide relative to each other, thereby saving energy.
Fig. 5 is a partially enlarged view of the flexible display device shown in fig. 4 according to the first embodiment of the present invention. As shown in fig. 4 and 5, in the present embodiment, the flexible display device 10 further includes a second transmission assembly. The second transmission assembly is respectively connected with the first main body 11, the second main body 12 and the rotating shaft 14 so as to drive the rotating shaft 14 to synchronously rotate when the second main body 12 and the first main body 11 relatively slide.
In particular, the second transmission assembly comprises a rack 31 and a pinion 32, which mesh with each other. The rack 31 is fixed to the first body 11, and the extending direction of the rack 31 is parallel to the relative sliding direction of the first body 11 and the second body 12. A gear 32 is fixed to the second body 12, and the gear 32 and the shaft 14 are drivingly connected in such a manner that they rotate at the same speed.
The gear 32 and the rotating shaft 14 are in transmission connection in a manner that the gear 32 and the rotating shaft 13 can rotate synchronously at the same rotating speed. For example, as shown in fig. 5, the flexible display device 10 further includes a third pulley 34 and a fourth pulley 35 connected by a second timing belt 33, the third pulley 34 is coaxially fixed with the gear 32, and the fourth pulley 35 is coaxially fixed with the rotation shaft 14.
According to the flexible display device provided by the embodiment, the rotating shaft 14 is directly driven by the power generated by the relative sliding of the second main body 12 and the first main body 11, and no additional driving device is needed, so that the energy is saved. For the flexible display device provided in any of the above embodiments, assuming that the relative sliding between the first body 11 and the second body 12 is uniform, the linear distance covered by one rotation of the rotation shaft 14 is constant. However, in practice, as the number of layers of the flexible display 13 wound on the rotating shaft 14 gradually increases, the radius of the cross section of the rotating shaft 14 gradually increases, and at this time, the length of the flexible display 13 wound on each rotation of the rotating shaft 14 also increases. It can be seen that in this case, the winding length of the flexible display 13 is greater than the linear distance of the rotation shaft 14, that is, the flexible display 13 is stretched, and the stretching is very likely to cause damage to the flexible display 13.
In view of this, the embodiment of the invention provides a flexible display device to avoid stretching the flexible display 13. Fig. 6 is a partially enlarged view of the flexible display device shown in fig. 4 according to the second embodiment of the present invention. As shown in fig. 4 and 6 in conjunction, the flexible display device 10 further includes a compensation device 15 connected between the fixed end a of the flexible display 13 and the first body 11. The compensation means 15 is used to elongate in the sliding direction of the first and second bodies 11 and 12 to compensate for the length of the flexible display 13 during the process of curling the flexible display 13.
Specifically, in the present embodiment, as shown in fig. 6, the compensating device 15 includes a fixed frame 151, a sliding block 152, and an elastic member 153 connected between the fixed frame 151 and the sliding block 152. The fixing frame 151 is fixed on the first main body 11, and the sliding block 152 is fixedly connected with the fixed end a of the flexible display 13.
For example, fig. 7 is a schematic structural diagram of a compensation device according to an embodiment of the present invention. As shown in fig. 7, the fixing frame 151 includes a left bottom plate and a right bottom plate disposed opposite to each other, and a vertical plate vertically fixed to the left bottom plate and the right bottom plate, wherein a first groove 1511 and a second groove 1512 are disposed on the left bottom plate and the right bottom plate, respectively, and the extending directions of the first groove 1511 and the second groove 1512 are both parallel to the relative sliding direction of the first body 11 and the second body 12. The left and right ends of the slider 152 are slidably engaged with the first groove 1511 and the second groove 1512, respectively. The elastic member 153 includes a spring, and both ends of the spring are fixedly connected to the vertical plate and the slider 152, respectively.
The number of the springs may be one or more, for example, as shown in fig. 6, the elastic member 153 includes three springs arranged in parallel at equal intervals along the length direction of the vertical plate. The fixing manner of the spring and the vertical plate and the spring and the slider 152 is not limited, for example, a first protrusion 1513 is provided on the vertical plate, and a second protrusion 1514 corresponding to the first protrusion 1513 is provided on the side wall of the slider 152. Both ends of the spring are fixed to the first protrusion 1513 and the second protrusion 1514, respectively.
According to the flexible display device provided by this embodiment, in the process that the curled end B of the flexible display 13 is gradually wound on the rotating shaft 14, as the number of layers of the flexible display 13 wound on the rotating shaft 14 increases, the fixed end a of the flexible display 13 is pulled towards the curled end B, so that by virtue of the elasticity of the elastic member 153, the flexible display 13 pulls the sliding block 152 to move towards the rotating shaft 14, which is equivalent to increasing the length of the flexible display 13, and the length compensation of the flexible display 13 is realized.
With the flexible display device provided in any of the above embodiments, for example, when the flexible display 13 is in the flattened state, the display surface of the flexible display 13 is located on the first plane. With the increase of the number of layers of the flexible display 13 wound on the rotating shaft 14, the thickness of the flexible display 13 on the rotating shaft 14 increases, which is equivalent to the increase of the diameter of the rotating shaft 14, so that the flexible display 13 is inclined, the display surface of the flexible display 13 forms a certain included angle with the first plane, and the more the number of layers of the flexible display 13 wound on the rotating shaft 14 is, the greater the inclination degree of the flexible display 13 is.
In view of this, in one embodiment, as shown in fig. 7, the compensating device 15 further comprises an oscillating piece 154. The swing member is located on a side of the slider 152 away from the elastic member 153, and is rotatably connected to the slider 152, a rotation axis of the swing member 154 is perpendicular to a relative sliding direction of the first body 11 and the second body 12, and a fixed end a of the flexible display 13 is fixedly connected to the swing member 154.
Specifically, the swinging member 154 may be a swinging lever or a swinging plate. The left and right ends of the slider 152 include protruding edges facing the flexible display 13, and bearings are fixed on the protruding edges. The left and right ends of the oscillating member 154 are respectively connected to the rotors of the bearings to ensure that the oscillating member 154 can oscillate with respect to the slider 152, and the oscillating direction of the oscillating member 154 is perpendicular to the relative sliding direction of the first and second bodies 11 and 12.
According to the flexible display device provided by the embodiment, the swing piece 154 is arranged at the fixed end a of the flexible display screen 13, and the fixed end a of the flexible display screen 13 can be subjected to angle fine adjustment by virtue of the rotation of the swing piece 154, so that the flexible display screen 13 is prevented from being inclined, and the user experience is improved.
In the flexible display device provided in any of the above embodiments, a flexible central control circuit board 40 may be further included, where the flexible central control circuit board 40 is connected to the fixed end a of the flexible display screen 14 in a bonding manner, and the flexible central control circuit board 40 is configured to drive the flexible display screen 14 to implement a display function.
The following takes the flexible display device shown in fig. 1, fig. 2, and fig. 3 as an example to describe in detail a specific structure of the central control circuit board of the flexible display device provided according to an embodiment of the present invention. It should be noted that, in this embodiment, since the rolling motion of the flexible display 13 is synchronized with the relative sliding motion of the first housing 11 and the second housing 12, the expansion amount of the flexible display 13 can be calculated according to the distance change caused by the sliding motion between the first housing 11 and the second housing 12, and the actual display area of the flexible display 13 can be determined according to the expansion amount.
Fig. 8 is a block diagram of a central control circuit board according to an embodiment of the present invention. As shown in fig. 8, the central control circuit board 40 includes a processing module 41, configured to determine a length of a second display area of the flexible display screen in the second state according to the acquired operation parameter of the motor, the operation direction of the flexible display screen, and the length of the first display area of the flexible display screen in the first state.
Specifically, the processing module 41 is specifically configured to:
first, the number of steps and the rotation speed of the motor are acquired.
The control command for setting the operating parameters of the motor is issued by the user, for example by means of a key of a smart car or a key on the steering wheel. The key for sending the control instruction comprises a motor rotating speed setting button, a motor step number control button and a screen body stretching control button.
And secondly, calculating the expansion and contraction quantity of the flexible display screen 13 according to the step number and the rotating speed of the motor and the running direction of the flexible display screen.
For example, as shown in FIG. 1, in the first state, the flexible display 13 has a first display area with a length of L1. At this moment, the adjustment instruction of obtaining motor operating parameter and flexible display 13 traffic direction includes: the rotating speed is V, the step number is N, and the running direction of the flexible display screen is shortened. It may be determined that the flexible display 13 has an amount of expansion (-V × N) in the second state compared to the first state, where "-" indicates a shortening; when the flexible display 13 is elongated in the direction of travel, "-" strain is more "+".
Then, the length L of the first display area of the flexible display 13 according to the amount of expansion and contraction and the first state1Determining L a length of a second display area of the flexible display 13 in the second state2Then L2＝L1-V*N。
As shown in FIGS. 1 and 2, the length L of the first display region1And length L of the second display area2It means that the length of the actual display area of the flexible display 13, and the sum of the length of the actual display area and the curled length (e.g., the first curled length and the second curled length) of the flexible display 13 is equal to the overall length of the flexible display 13.
According to the flexible display device provided by the embodiment, the actual display area of the flexible display screen 13 depends on the operation parameters of the motor, and for the same flexible display device 13, the actual display area of the flexible display screen 13 changes along with the change of the operation parameters of the motor, so that the use mode of the flexible display device is further enriched.
In one embodiment, the operating parameter of the electric machine further comprises a direction of rotation. In this case, the processing module 41 is further configured to determine the operation direction of the flexible display screen according to the rotation direction of the motor and by combining a preset corresponding relationship between the rotation direction of the motor and the rotation direction of the rotating shaft.
The rotation direction of the motor indicates the relative sliding direction of the first body 11 and the second body 12, and the rotation direction of the rotating shaft 14 indicates the running direction of the flexible display 13, so the corresponding relationship between the rotation direction of the motor and the rotation direction of the rotating shaft 14 is equivalent to the corresponding relationship between the relative sliding direction of the first body 11 and the second body 12 and the running direction of the flexible display 13. For example, a clockwise rotation of the preset motor corresponds to a clockwise rotation of the shaft 14, and a clockwise counter-rotation of the preset motor corresponds to a counterclockwise rotation of the shaft 14. In this case, when the motor rotates clockwise, the first body 11 and the second body 12 slide close to each other, and accordingly, the rotation shaft 14 rotates clockwise, and the flexible display 13 is curled and shortened. When the motor rotates counterclockwise, the first body 11 and the second body 12 slide away, and accordingly, the rotating shaft 14 rotates counterclockwise, and the flexible display 13 is extended.
According to the flexible display device provided by the embodiment, the running direction of the flexible display screen 13 can be automatically identified according to the rotating direction of the motor, manual input is not needed, and the automation level of the flexible display device is further improved.
In one embodiment, the processing module 41 further comprises a resolution matching module 42 for determining a length L of the second display area for the center control circuit board 402Touch control module 43 is used to determine L a length of the second display region2And (5) matching the touch control effective area.
