wherein, the joint groove certainly the casing lateral surface is to being close to the opening of display piece direction reduces gradually, just the extruded article extrude in the joint inslot, so that when the display piece receives external force impact, the display piece is dragged the extruded article makes the extruded article chucking in the joint inslot.

The embodiment of the application also provides electronic equipment, which comprises the high-strength display screen.

Above-mentioned scheme is through covering the cladding in flexible layer outer wall and part the extruded article extrusion in the joint inslot that shows the relative both sides face of piece, and make the joint groove reduce gradually towards the opening that is close to display piece direction outside the casing, so that when the display screen fell, the display piece receives the barrier and strikes and when dragging its both sides limit, extruded article can the chucking in the joint inslot, and along with the extruded article gradually toward pulling outward, the extruded article diminishes because of self deformation and joint groove open-ended, the extrusion force grow gradually, thereby chucking that can be better is in the joint inslot.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 and 2, an embodiment of the present application provides a high-strength display screen 100, which includes an annular housing 10 and a display 20 disposed on the housing 10. The housing 10 is used to be fixed to an electric device or to a specific application scene, for example, the housing 10 may be fixed to a housing of a tablet computer to form a tablet computer, or the housing 10 may be fixed to a wall to serve as a suspended display screen 100 for advertising, and the like.

Further, referring to fig. 1-5, the inner side of the casing 10 is surrounded by a clamping groove 11, and the display element 20 includes a flexible layer 21 stacked on top of each other and a plurality of light emitting elements 22 disposed on the flexible layer 21. The flexible layer 21 and the two opposite ends of the light emitting members 22 are fixed in the engaging grooves 11, so as to fixedly connect the display member 20 and the housing 10. It should be noted that, in an embodiment, the flexible layer 21 is made of a plastic material or a rubber material with a display function, such as graphene, so that the formed display element 20 can be made into a curved screen, or the formed display screen 100 can be bent at will, and the graphene can be used as a curved screen as part of the prior art, which is not described herein in detail.

In one embodiment, the light emitting element 22 is an LED lamp bead, and presents different images under the control of an internal control system and an electric field of the circuit.

Still further, since the obstacle may impact the display screen 100 when the display screen 100 falls or is impacted, the display screen 100 may be locally stressed and the two ends of the display screen 100 may be pulled, which may cause damage to the fixing portion of the display screen 100 and the housing 10 or damage to the display screen 100 due to the display screen 100 being pulled out of the housing 10, the display screen 100 further includes the extrusion member 30. Wherein the expression member 30 is wrapped around the peripheral wall of the flexible layer 21 and partially covers opposite sides of the display member 20. And when display screen 100 assembles, extrude extruded article 30 to joint inslot 11 in to display screen 100 falls and receives the barrier overall arrangement and assaults and when dragging its both ends, extruded article 30 can the chucking in joint inslot 11, thereby prevents that display screen 100 from being dragged out joint inslot 11 and leading to the problem that display screen 100 damaged.

Further, joint groove 11 reduces gradually from the casing 10 outside to the opening that is close to the 20 directions of display member, in order when display screen 100 drops and receives the part to drag, display member 20 pulls extruded article 30 when moving to casing 10 inboard, extruded article 30 receives the extrusion power degree of joint groove 11 medial surface bigger and bigger, and when extruded article 30 reachd the nearer position of joint groove 11 opening, extruded article 30 is extruded and is become the block structure that can not warp again of a stereoplasm and is by the chucking in joint groove 11, thereby can be better prevent that extruded article 30 from being pulled out joint groove 11 outside and the problem that display member 20 that leads to breaks away from casing 10.

In an embodiment, the extrusion member 30 is made of a high-elasticity material, such as polymer rubber, etc., and due to the high elasticity of the extrusion member 30, when the extrusion member 30 is pushed toward the center of the housing 10 by the impact of the display member 20 and is extruded into a hard block, and after the impact force disappears, the extrusion member 30 drives the display member 20 to reset by its own elasticity, thereby restoring the normal use state of the display screen 100.

In one embodiment, the extrusion 30 is injection molded or adhesively secured to the opposing peripheral walls of the display member 20 and partially covers the opposing sides of the display member 20 to fixedly attach the extrusion 30 to the display member 20.

Referring to fig. 5 and 7, in one embodiment, the pressing member 30 has a table-like configuration conforming to the shape of the catching groove 11. It is obvious that the present invention is not limited thereto, and as in another embodiment, the pressing member 30 may also be a block structure having a volume larger than that of the catching groove 11, so that when the pressing member 30 is pressed into the catching groove 11, the pressing member 30 is interference-fitted into the catching groove 11 to fill the catching groove 11, so as to ensure the tightness of the fit between the pressing member 30 and the casing 10, and prevent the display member 20 from shaking back and forth along the thickness direction of the casing 10 to cause the screen to be unstable.

Referring to fig. 5, in order to further ensure the stability of the extruding member 30 extruded in the clamping groove 11 and prevent the extruding member 30 from being pulled by the display member 20 to separate from the clamping groove 11, the display screen 100 further includes at least two pressure sensors 40 and a heating member 50 disposed in the clamping groove 11 and electrically connected to the pressure sensors 40, so that when the housing 10 is impacted and reaches the threshold of the pressure sensors 40, the pressure sensors 40 send signals to the heating member 50, and the heating member 50 heats the clamping groove 11, thereby promoting the expansion of the extruding member 30 to expand the volume thereof, and enabling the extruding member 30 to be better clamped in the clamping groove 11.

Specifically, the housing 10 has a first surface 12 and a second surface 13 provided on the outside, and at least two pressure sensors 40 are provided on the first surface 12 and the second surface 13. The housing 10 further has a third surface 14 and a fourth surface 15 disposed in the engaging groove 11, the heating member 50 is disposed on the third surface 14 and the fourth surface 15, and when the heating member 50 is disposed on the third surface 14 and the fourth surface 15, the heating member 50 can be in direct contact with the extrusion member 30.

Note that the first surface 12 and the second surface 13 are respectively located on an outer wall of the housing 10 in the thickness direction, that is, on an outer side surface parallel to the display surface of the display member 20. When the display screen 100 is dropped in a direction perpendicular to the display member 20, the following two situations exist in the sequence of the landing points of the display screen 100:

first, the display screen 100 may contact an obstacle on the ground to generate an impact, and at this time, the display member 20 is impacted to pull the pressing member 30 to move toward the center, and the pressing member 30 is pressed in the catching groove 11. Then, the display screen 100 bounces on the ground and makes the first face 12 or the second face 13 on the shell impact with the ground, at this moment, the impact of ground and first face 12 or the second face 13 reaches the threshold value of pressure sensor 40, and pressure sensor 40 controls the piece inflation that generates heat in order to enlarge the volume of extruded piece 30 to make in the better chucking joint groove 11 of extruded piece 30 ability, thereby avoid the condition that the display piece 20 is pulled out of chucking joint groove 11, guarantee the normal use of display screen 100.

The second surface 12 or the second surface 13 contacts the ground first, at this time, the sensors on the first surface 12 and the second surface 13 reach the threshold value first, and the heating element 50 is controlled to heat the extrusion member 30, so that the extrusion member 30 can be better prevented from being separated from the clamping groove 11 during subsequent bounce and impact.

It should be noted that the threshold of the pressure sensor 40 is determined according to the impact resistance of the corresponding electronic device, for example, in an electronic device not suitable for impact, the threshold is reached when the threshold of the pressure sensor 40 is twice the gravity of the electronic device, and in an electronic device capable of resisting a certain impact, the threshold of the pressure sensor 40 is ten times the gravity of the electric device.

In an embodiment, the pressure sensors 40 are uniformly distributed on the first surface 12 and the second surface 13, and the heating member 50 is a heating sheet structure, and is uniformly distributed on the third surface 14 and the third surface 14, so that when the pressure sensors 40 control the heating member 50 to heat, the heating member 50 can uniformly heat the surface of the extrusion member 30 contacted with the heating member 50, thereby uniformly expanding the extrusion member 30, and preventing the problem of loose clamping caused by too large or too small local expansion.

Referring to fig. 3-5, in order to prevent the screen from being pulled out due to the excessive impact force when the high-strength display screen 100 falls to the ground, a clamping assembly 60 is further included. Specifically, referring to fig. 5, the clamping member 60 is circumferentially provided on the outer circumferential surface of the display member 20, so that in the process of fixing the display member 20 to the catching groove 11, the clamping member 60 can clamp the display member 20 in the thickness direction of the display member 20 by fixing the clamping member 60 on the outer circumferential surface of the display member 20, sleeving the pressing member 30 on the outside of the clamping member 60, and then pressing the end with the pressing member 30 into the catching groove 11, when the pressing member 30 is thermally expanded.

Further, in a particular embodiment, clamp assembly 60 includes a first clamp 61, a second clamp 62, and two guides 64. Specifically, the first clamping member 61 and the second clamping member 62 are provided on opposite sides of the display member 20 to be relatively movable in the thickness direction of the display member 20. One end of each guide member 64 extends from the side of the display member 20 in a direction away from the display member 20, and the first clamping member 61 and the second clamping member 62 are sleeved and can move on the guide member 64, so that when the pressing member 30 expands due to heat, the pressing member 30 can push the first clamping member 61 and the second clamping member 62 to move on the guide member 64 to be close to the display member 20, thereby clamping the display member 20.

In one embodiment, the guide 64 is an angled cylinder.

Still further, the first clamp 61 includes an expansion part 611, a first clamp part 612, and a first engaging part 613, which are provided in this order and perpendicular to each other. The second clamp 62 includes a receiving portion 621, a second clamp portion 622, and a second engaging portion 623 that are provided in this order and are perpendicular to each other. The telescopic part 611 can move in the receiving part 621 along a direction perpendicular to the display member 20, so that when the pressing member 30 pushes the first clamping member 61 and the second clamping member 62 to move, the telescopic part 611 moves in the receiving part 621, so as to adaptively adjust the heights of the first clamping member 61 and the second clamping member 62 to be clamped on the two guide members 64. Preferably, the end surface of the receiving portion 621 facing the expansion part 611 is provided with a receiving groove 621a, and the cross-sectional area of the expansion part 611 is smaller than or equal to the cross-sectional area of the receiving groove 621a, so that when the first clamping member 61 and the second clamping member 62 are assembled, the expansion part 611 extends into the receiving portion 621 and can move in the receiving groove 621 a.

Specifically, in order to facilitate sleeving the first clamping member 61 and the second clamping member 62 on the guide member 64, the first clamping member 61 is provided with a first connecting hole 61a having the same diameter as the guide member 64, and the second clamping member 62 is provided with a second connecting hole 62a having the same diameter as the guide member 64. The first clamping member 61 is sleeved on the guide member 64 through the first connecting hole 61a and can move on the guide member 64, and the second clamping member 62 is sleeved on the guide member 64 through the second connecting hole 62a and can move on the guide member 64.

In the above-described embodiment, since one end of each of the two guide members 64 is offset from the side surface of the display member 20 in the direction of offsetting the display member 20, that is, the two guide members 64 are obliquely disposed on the display member 20, and when the two guide members 64 are moved closer to the display member 20 from the direction away from the display member 20, the distance between the two guide members 64 becomes smaller. According to the present invention, the first clamping member 61 and the second clamping member 62 are sleeved on the guide member 64, and the telescopic part 611 extends into the receiving groove 621a, so as to realize the movable connection of the first clamping member 61 and the second clamping member 62 along the thickness direction of the display member 20, so that when the extrusion member 30 is forced to push the first clamping member 61 and the second clamping member 62 to move on the guide member 64, the telescopic part 611 of the first clamping member 61 moves in the receiving groove 621a of the second clamping member 62, so as to change the total height between the first clamping member 61 and the second clamping member 62, and the total height between the first clamping member 61 and the second clamping member 62 is always changed along with the height between the two guide members 64.

Preferably, the clamping assembly 60 further comprises a resilient member 63. Specifically, one end of the elastic member 63 is fixed on the end surface of the expansion part 611 facing the receiving groove 621a, and the other end of the elastic member extends into the receiving groove 621a and abuts against the inner wall of the receiving groove 621a, so that when the high-strength display screen 100 is released from collision and the extrusion member 30 is cooled, the elastic member 63 drives the extrusion member 30 to restore its original shape under the action of the elastic force thereof, thereby preventing the extrusion member 30 from being damaged in a tight state for a long time, and prolonging the service life of the high-strength display screen 100.

In one embodiment, the elastic member 63 is a spring.

Further, the telescopic portion 611 has a first pressing surface 61b facing away from the display member 20 and extending in the thickness direction of the display member 20, the first clamping portion 612 has a second pressing surface 61c facing away from the display member 20 and extending in the length direction of the display member 20, the receiving portion 621 has a third pressing surface 62b facing away from the display member 20 and extending in the thickness direction of the display member 20, and the second clamping portion 622 has a fourth pressing surface 62c facing away from the display member 20 and extending in the length direction of the display member 20. Preferably, the first pressing surface 61b and the third pressing surface 62b extend in opposite directions, and the second pressing surface 61c and the fourth pressing surface 62c extend in the same direction.

Furthermore, in order to better prevent the display element 20 from being pulled out of the clamping groove 11, the opposite two side surfaces of the display element 20 are provided with a limiting groove (not shown) corresponding to the first clamping portion 613 and the second clamping portion 623, so that when the extrusion element 30 extrudes the first clamping member 61 and the second clamping member 62, the first clamping portion 613 and the second clamping portion 623 can extrude the extrusion element 30 towards the direction of the limiting groove, so that the extrusion element 30 is filled into the limiting groove, and the extrusion element 30 filled into the limiting groove can prevent the display element 20 from being pulled out laterally due to the extrusion of the limiting groove from the upper end and the lower end.

In order to prevent the display member 20 from being pulled out of the engaging groove 11 due to too large impact force of the impact, the display member 20 further includes a stopper 25 disposed on the light-adjusting member 24 and the flexible layer 21. Preferably, the distance between the limiting parts 25 arranged on the light modulation part 24 and the flexible layer 21 is greater than the height of the clamping groove 11, so that when the display part 20 is laterally stressed, the two limiting parts 25 block the opening of the clamping groove 11, and the display part 20 is prevented from being directly pulled out of the clamping groove 11.

In one embodiment, the position limiting member 25 includes, but is not limited to, a quick-assembly structure, etc.

In the specific anti-pulling process of the high-strength display screen 100, when the first side 12 or the second side 13 is impacted and the pressure sensor 40 detects the pressure and reaches the threshold value, the heating element 50 is controlled to heat the extrusion member 30, the extrusion member 30 is heated to expand, and the expanded extrusion member 30 contacts the first extrusion surface 61b and the second extrusion surface 61c of the first clamping member 61 and contacts the third extrusion surface 62b and the fourth extrusion surface 62c of the second clamping member 62. At this time, the pressing members 30 press the second pressing surface 61c and the fourth pressing surface 62c toward the display member 20 from both upper and lower ends in the thickness direction of the display member 20, so that the first clamping portion 612 and the second clamping portion 622 move in the direction of the display member 20 to press the pressing members 30 between the first clamping portion 612 and the display member 20 and between the second clamping portion 622 and the display member 20, thereby clamping the display member 20. At this time, the telescopic part 611 of the first clamping member 61 is inserted into the receiving groove 621a of the second clamping member 62, so that the overall height of the first clamping member 61 and the second clamping member 62 is changed, and the height thereof is changed according to the height change of the two guide members 64.

When the pressing member 30 is expanded by heat to press the first pressing surface 61b and the third pressing surface 62b, the pressing member 30 pushes the first clamping member 61 and the second clamping member 62 to move on the guide member 64, and at this time, as the guide member 64 is gradually inclined downward, when the first clamping member 61 and the second clamping member 62 move downward along the guide member 64, the first clamping portion 612 and the second clamping portion 622 move in a direction close to the display member 20 to press the pressing member 30 to clamp the display member 20, so that the acting force of the pressing member 30 in the length direction of the display member 20 is partially converted into a force in the thickness direction of the display member 20 to clamp the display member 20 and prevent the display member 20 from being pushed out of the clamping groove 11.

To facilitate assembly of the display member 20 with the housing 10, the housing 10 includes a first body 16 and a second body 17 that are detachably disposed. Specifically, the first body 16 has a first click space 18, and the second body 17 has a second click space 19. And first joint space 18 and second joint space 19 enclose to close in order to form joint groove 11, in order when above-mentioned display screen 100 assembles, place the extruded piece 30 on the display part 20 in first joint space 18 on the first body 16 respectively earlier, or place the extruded piece 30 on the display part 20 in second joint space 19 on the second body 17 respectively, then close and be fixed in on first body 16 or the second body 17 through closing other second body 17 or first body 16 lid, in order to realize the equipment of display part 20 and casing 10, avoided because extruded piece 30 is greater than joint groove 11 and the problem that display part 20 and casing 10 can't install.

In an embodiment, the display screen 100 further includes a fixing member (not shown), the first body 16 has a first fixing hole 16a along a thickness direction thereof, and the second body 17 has a second fixing hole 17a along the thickness direction thereof, the second fixing hole corresponding to the first fixing hole 16 a. Wherein the fixing member can be inserted into the first fixing hole 16a and the second fixing hole 17a to fix the first body 16 and the second body 17. Specifically, the fixing member is a screw.

Furthermore, the clamping groove 11 is opened at the central line of the inner side of the shell 10. At this time, the flexible layer 21 encloses the housing 10 to form a first gap 21a and a second gap 21b facing opposite directions. The first gap 21a is used to prevent the display member 20 from directly contacting an obstacle when the display screen 100 is dropped. The second gap 21b is used for mounting electronic components such as circuit boards, electric wires, and the like.

It should be noted that, in the above-mentioned solution, the fastening groove 11 is opened at the central line position of the inner side surface of the housing 10 to reserve the first gap 21a, so that when the display screen 100 is on the ground and the display 20 is parallel to the horizontal plane, because the housing 10 protrudes outward relative to the display 20, when the obstacles are uneven, the housing 10 can firstly counteract the impact force of a part of the obstacles, thereby preventing the obstacles from directly contacting the display 20 to cause the display 20 to bear a large impact force.

Still further, the display member 20 further includes an epoxy layer 23. The epoxy layer 23 is attached to the side of the flexible layer 21 where the light emitting members 22 are disposed, and covers the light emitting members 22, so as to achieve the anti-falling, anti-scratch, and waterproof properties of the display member 20.

Referring to fig. 5-8, in order to emit light of different colors from the light-emitting member 22 to achieve a specific program effect, the display member 20 further includes a light modulation layer. The light-adjusting layer is attached to the epoxy resin layer 23, so that when light emitted by the light-emitting elements 22 passes through the epoxy resin layer 23 and the light-adjusting layer, the light-adjusting layer controls the color of the emitted light.

Further, the dimming layer further includes a first conductive layer 241, a liquid crystal layer 242, and a second conductive layer 243 which are stacked. The first conductive layer 241 or the second conductive layer 243 is attached to the epoxy resin layer 23 to implement the arrangement of the light modulation layer.

Preferably, the first conductive layer 241 and the second conductive layer 243 are transparent conductive polymer material layers.

Specifically, a plurality of liquid crystal molecules (not shown) and dye molecules (not shown) are disposed in the liquid crystal layer 242 and are perpendicular to the space between the first conductive layer 241 and the second conductive layer 243, and when the light emitted from the light emitting element 22 irradiates the first conductive layer 241 or the second conductive layer 243, the light directly passes through the plurality of liquid crystal molecules and dye molecules and exits the housing 10 from the opposite second conductive layer 243 or the first conductive layer 241. When a voltage is applied across the first conductive layer 241 and the second conductive layer 243, the voltage creates an electric field between the first conductive layer 241 and the second conductive layer 243. The electric field drives the liquid crystal molecules and the dye molecules between the first conductive layer 241 and the second conductive layer 243 to rotate until the liquid crystal molecules and the dye molecules are parallel to the first conductive layer 241 and the second conductive layer 243, and at this time, when the light irradiates on the first conductive layer 241 or the second conductive layer 243, the light directly irradiates on the side surfaces of the plurality of dye molecules, and penetrates through the dye molecules and exits the housing 10 through the opposite second conductive layer 243 or the first conductive layer 241, so that the color of the light emitted from the housing 10 by the light emitting element 22 is changed. Further, when the voltage applied to the first conductive layer 241 or the second conductive layer 243 is different, the magnitude of the electric field formed between the first conductive layer 241 and the second conductive layer 243 is also different, so that the number of the dye molecules flipped is different, and the liquid crystal layer 242 exhibits different colors. When the color of the liquid crystal layer 242 is darker, the light transmitted is darker, and when the color of the liquid crystal layer 242 is lighter, the light transmitted is brighter. The display screen 100 is suitable for different environments by arranging the light adjusting member 24 on the epoxy resin layer 23 to change the color of the light emitted from the display member 20.

The embodiment of this application still provides an consumer, uses the aforesaid high strength display screen 100 to support, therefore, the beneficial effect that above-mentioned display screen 100 has, the consumer of this embodiment has equally, and it is no longer repeated here.

It should be noted that the electric device includes, but is not limited to, a mobile phone, a tablet computer, an intelligent wearable device, and the like.
