Example 1
The application provides a scroll type flexible screen, fig. 1 is a schematic structural view of the scroll type flexible screen according to the first embodiment of the application, and fig. 2 is an enlarged partial structural view of the scroll type flexible screen according to the first embodiment of the application.
As shown in fig. 1, the roll-type flexible screen includes a first flexible crimping assembly 100A and a second flexible crimping assembly 100B connected in opposition, the first flexible crimping assembly 100A and the second flexible crimping assembly 100B being fixedly connected by a fixing assembly 300.
The scroll type flexible screen comprises a winding posture and a flattening posture: the second end of the first flexible crimping assembly 100A and the second end of the second flexible crimping assembly 100B are capable of being gradually rolled toward the respective first ends to a rolled configuration (as shown in fig. 1) and back from the rolled configuration to a flat configuration. The upper ends of the first and second flexible crimping assemblies 100A and 100B are fixedly connected, and the lower ends of the first and second flexible crimping assemblies 100A and 100B can be gradually rolled up to the upper ends, it may be understood that the roll structure formed by rolling up the lower ends becomes gradually larger as the lower ends are partially rolled up for the first and second flexible crimping assemblies 100A and 100B. And the lower end of the first flexible crimping component 100A is turned to the left, the second flexible crimping component 100B is curled to the right, and the two directions are opposite.
As shown in fig. 2, the surface of the second flexible crimping component 100B facing away from the first flexible crimping component 100A is provided with a flexible screen body 200, and in a crimped state of the second flexible crimping component 100B, the flexible screen body 200 is crimped inside, and after the first flexible crimping component 100A and the second flexible crimping component 100B are unwound and the posture is changed to a flat posture, the flexible screen body 200 is completely exposed for display, in combination with fig. 1 and 2.
Further, in the flat posture, the first flexible crimping component 100A and the second flexible crimping component 100B are magnetically connected at a plurality of positions along a first direction, which is an up-down direction as shown in fig. 1. It will be understood that as the first flexible crimping component 100A and the second flexible crimping component 100B gradually move upwards, the magnetic attraction connection parts of the two become more and more, and when the scroll type flexible screen is in a flat posture, the first flexible crimping component 100A and the second flexible crimping component 100B are magnetically attracted in a flat plate structure along the first direction at a plurality of positions, and the flexible screen body 200 is exposed for display.
The first flexible crimping component 100A and the second flexible crimping component 100B only need to ensure unidirectional strength in the Z-axis direction (thickness direction), so that the first flexible crimping component 100A and the second flexible crimping component 100B can be made thin, and the two flexible crimping components are integrated to ensure bidirectional strength, namely, the strength of the exposed part of the flexible screen body 200 can be ensured in the process of displaying the flexible screen body 200.
Further, the first flexible crimping assembly 100A and the second flexible crimping assembly 100B have the same structure, fig. 3 is a schematic structural diagram of the first flexible crimping assembly 100A of the scroll type flexible screen according to the first embodiment of the present application, and as shown in fig. 3, the first flexible crimping assembly 100A includes a crimpable substrate 1 and a plurality of magnetic members 2.
The plurality of magnetic members 2 are sequentially arranged on the first surface of the crimpable base 1 in the first direction. When in the flat posture, the first surfaces of the crimpable substrate 1 of the first flexible crimping assembly 100A and the crimpable substrate 1 of the second flexible crimping assembly 100B are opposite to each other, and the magnetic pieces 2 sequentially arranged along the X-axis direction on the first flexible crimping assembly 100A magnetically attract the magnetic pieces 2 sequentially arranged along the X-axis direction on the second flexible crimping assembly 100B in a one-to-one correspondence manner along the Z-axis direction.
It should be noted that the first surface of the crimpable substrate 1 of the first flexible crimping assembly 100A faces the surface of the second flexible crimping assembly 100B when in the flat posture, and the first surface of the crimpable substrate 1 of the second flexible crimping assembly 100B faces the surface of the first flexible crimping assembly 100A when in the flat posture. The flexible screen body 200 is disposed on the second surface of the second flexible crimp assembly 100B.
Further, the magnetic attraction surfaces of the magnetic members 2 on the first flexible crimping unit 100A and the second flexible crimping unit 100B may be set to be different magnetic properties, or the magnetic members 2 on the first flexible crimping unit 100A may be uniformly set to be iron, and the magnetic members 2 on the second flexible crimping unit 100B may be uniformly set to be magnets. The present embodiment is not limited thereto.
With continued reference to fig. 3, the first flexible crimping assembly 100A further includes a cover 3 and an elastic member 4, the cover 3 being disposed over the first surface of the crimpable substrate 1 and being bendable with the crimpable substrate 1, the plurality of magnetic members 2 and the plurality of elastic members 4 being disposed between the crimpable substrate 1 and the cover 3 along the X-axis direction along the crimpable substrate 1. The elastic member 4 can elastically deform along the Z-axis direction, that is, after the covering body 3 is pressed down, the elastic member 4 can elastically compress.
In the magnetic attraction process of the first flexible crimping assembly 100A and the second flexible crimping assembly 100B along the Z-axis direction, the magnetic pieces 2 attract each other, after the cladding bodies 3 are contacted with each other, the elastic pieces 4 are stressed, the elastic pieces 4 elastically deform so as to slow down the attachment process after the magnetic attraction, the sound generated when the first flexible crimping assembly 100A and the second flexible crimping assembly 100B are magnetically attracted is reduced, and the use comfort of products is improved.
The crimpable substrate 1 is used as an outer layer, and the hardness thereof should be larger than that of the coating body 3. In the embodiment of the application, leather or rubber is selected as the crimpable substrate 1, the coating body 3 is made of cloth material with certain micro elasticity, and the coating body 3 can be sewn on the crimpable substrate 1, and the periphery of the magnetic element 2 and the periphery of the elastic element 4 are sewn, so that the magnetic element 2 and the elastic element 4 are fixed on the crimpable substrate 1.
Further, the elastic piece 4 is provided with an arc surface structure, the edge of the arc surface structure is abutted against the base body 1, and the arc top of the arc surface structure is abutted against the coating body 3. Namely, after the elastic piece 4 receives the pressure in the Z-axis direction, the radian of the elastic piece 4 is increased, and the two ends of the elastic piece 4 move outwards, so that the pressure dispersion is realized.
Further, the elastic member 4 and the magnetic member 2 each extend in a third direction perpendicular to the first direction. It will be understood that, if the X-axis direction in the drawing is the longitudinal direction of the crimpable substrate 1, the third direction is the width direction of the crimpable substrate 1, and the magnetic element 2 and the elastic element 4 are each in the shape of a bar, preferably, the longitudinal directions of the magnetic element 2 and the elastic element 4 coincide with the width direction of the crimpable substrate 1, and the width directions of the magnetic element 2 and the elastic element 4 coincide with the longitudinal direction of the crimpable substrate 1.
And the narrower the width of the magnetic member 2 and the elastic member 4, the closer the surface of the crimpable base 1 is to the smooth arc surface when it is rolled up, in the embodiment of the present application, the width of the magnetic member 2 and the elastic member 4 is set according to the actual requirement.
Further, the suture direction of the sheathing body 3 is in a third direction perpendicular to the first direction, and openings are formed at both ends of the crimpable base body 1 in the width direction, thereby facilitating insertion of the magnetic member 2 and an elastic member 4 described below.
Further, the elastic member 4 and the magnetic member 2 are sequentially arranged at intervals in the first direction. Namely, one elastic member 4 is provided between two adjacent magnetic members 2, and one magnetic member 2 is provided between two adjacent elastic members 4. In the process of mutual magnetic attraction of the magnetic pieces 2 during crimping, the elastic pieces 4 are uniformly arranged along the X-axis direction to disperse pressure from the Z-axis direction, so that when any group of magnetic pieces 2 are mutually magnetically attracted, one side of each magnetic piece 2 can be subjected to the elastic buffering action of the elastic piece 4, and noise generated during magnetic attraction is reduced.
In the embodiment of the present application, the elastic member 4 is provided as a steel sheet, and of course, the elastic member 4 may be made of plastic sheet, copper sheet, or the like.
Further, as shown in fig. 1, in the flat posture, the elastic member 4 between any two adjacent magnetic members 2 in the first flexible curling assembly 100A and the elastic member 4 between two magnetic members 2 magnetically attracted to each other in the second flexible curling assembly 100B are arranged in a staggered manner along the left-right direction, and the elastic member 4 arranged in a staggered manner is shown in fig. 4.
The elastic piece 4 arranged in a staggered manner can ensure that the thickness is smaller in the flat gesture, and the light and thin design is easy to realize.
