Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely a few embodiments of the invention and are not to be taken as a comprehensive embodiment. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Example 1:
the invention provides a display screen protection device, as shown in fig. 1 to 3, for protecting a display device including a sliding and rolling display screen 10, wherein the sliding and rolling display screen 10 mainly comprises a flexible display screen 11 and a sliding shaft 12. The flexible display screen 11 can be wound on the sliding shaft 12, or can only be wound around the sliding shaft 12, and the flexible display screen 11 is driven to be unfolded through the rotation and the sliding of the sliding shaft 12.
As shown in fig. 1 to 3, the display screen protection device includes a flexible protection layer 21, a storage member 22, and a support member 23. The retraction member 22 includes, but is not limited to, a reel on which one end of the flexible cover 21 is wound. The winding and unwinding member 22 realizes winding or unwinding of the flexible protective layer 21 by forward rotation or reverse rotation of the reel. The supporting member 23 includes, but is not limited to, a protective case, to which the slide shaft 12 is rotatably connected, and the other end of the flexible protective layer 21 is connected. The supporting member 23 supports the flexible protection layer 21, so that the flexible protection layer 21 can be shielded on the display surface side of the flexible display 11.
In the unfolding direction of the sliding and rolling display screen 10, the reel and the protective shell are arranged on two sides of the display screen in parallel, and the sliding and rolling display screen 10 is located between the reel and the protective shell. In other words, the reel can be rotated and the slide shaft 12 and the protective case can be moved in a direction to approach or separate from the reel relative to the reel. The flexible protective layer 21 is located on one side of the display surface of the flexible display screen 11 and used for shielding the flexible display screen 11 so as to prevent an external object from directly acting on one side of the display surface of the flexible display screen 11, and therefore the scratch resistance and the impact resistance of the flexible display screen 11 are improved. The diameter size and the arrangement position of the reel and the size of the protective shell are preferably such that the flexible protective layer 21 can be parallel to the flexible display screen 11.
As shown in fig. 1 to 3, when the slide shaft 12 is moved in a direction away from the reel by rotating and sliding, the flexible display 11 is unfolded. Meanwhile, the sliding shaft 12 is rotatably connected with the protective shell, the reel releases the flexible protective layer 21 in an active rotation or passive rotation mode, and the protective shell moves in the direction away from the reel to synchronously drive the flexible protective layer 21 to be unfolded so as to protect the flexible display screen 11. When the reel rotates reversely to wind the flexible protection layer 21, the reel pulls back the protection shell through the flexible protection layer 21, so that the flexible protection layer 21 is retracted. Meanwhile, the protective shell synchronously drives the sliding shaft 12 to move in the direction close to the reel, so that the flexible display screen 11 of the sliding and rolling display screen 10 is retracted.
As shown in fig. 7, in some embodiments, the reel as the retractable member 22 is not limited to a solid reel, and the reel may be designed as a hollow reel. The hollow reel is of a hollow structure, so that driving components such as a circuit board, a driving motor and a lead for driving the hollow reel to rotate can be installed in the hollow structure, and the space occupied by the driving components outside the reel is saved. The diameter and the arrangement position of the hollow reel and the size of the protective shell are preferably set so that the flexible protective layer 21 can be parallel to the flexible display screen 11.
It should be understood that the structure of the retractable member 22 is not limited to a reel, and any structure can be used as long as the retractable or releasable action of the flexible protection layer 21 can be achieved. For example, the retractable part 22 may be designed as a driving motor, the driving motor is connected to a lead screw, the lead screw is connected to a slider in a threaded manner, and the flexible protective layer 21 is connected to the slider, so that the driving motor drives the slider to move through the lead screw, and thus the flexible protective layer 21 is far away from or close to the protective housing at one end of the retractable part 22 along the expansion direction of the flexible display screen 11, and the retraction or release of the flexible protective layer 21 can also be realized, at this time, the retractable part 22 is specifically represented as a slider. For another example, the driving motor is connected to a gear, the gear is meshed with and matched with a rack, the driving motor moves on the rack through the gear, the flexible protection layer 21 is connected to the driving motor, and the flexible protection layer 21 can also be retracted or released, at this time, the retractable member 22 is embodied as the driving motor. Of course, the retractable member 22 can also be designed to fold or release the flexible protection layer 21.
As shown in fig. 3, the protective case as the supporting member 23 includes a curved case 23a and an end face case 23b, and the curved case 23a is wound around the outside of the slide shaft 12 of the slide-rolling display screen 10 for protecting the slide shaft 12 and the flexible display screen 11 wound around the position of the slide shaft 12. The two end surface shells 23b are respectively arranged at two ends of the curved surface shell 23a, and two ends of the slide shaft 12 are respectively rotatably connected with the two end surface shells 23 b. The manner of rotatable connection between the slide shaft 12 and the end surface shell 23b includes, but is not limited to, a hole drilled in the end surface shell 23b, and a manner of inserting the shaft portion of the slide shaft 12 into the hole. Alternatively, the end surface case 23b is grooved and receives balls, and the slide shaft 12 is rotated by the balls. Of course, the protective shell may be designed to be a bracket-type structure or a rectangular semi-box-type structure as a whole.
As shown in fig. 4 to 6, a connecting portion, specifically, a connecting groove 232 opened on the curved surface case 23a or the end surface case 23b is provided in the protective case. The flexible protection layer 21 is detachably connected with a fixing member 41, and the fixing member 41 is connected with a fixing arm 42 and a connecting head 43. Wherein, two fixed arms 42 are arranged at intervals to form slots, and the end of the flexible protective layer 21 is inserted in the slots. Alternatively, the two fixing arms 42 are connected to the fixing member 41 to form a structure including, but not limited to, an F-shape, and may also be a V-shape, for example. In order to make the connection between the flexible protection layer 21 and the fixing element 41 more stable, the end of the flexible protection layer 21 may be coated with glue, so that the flexible protection layer 21 is adhered in the slot formed by the two fixing arms 42.
It should be noted that one or more connecting portions may be provided, and one connecting portion may be provided at a central portion of the curved shell 23 a. The plurality of connecting portions may be provided one on each of the two end surface shells 23b, and the remaining connecting portions may be uniformly provided along the length direction of the curved surface shell 23 a. Of course, the plurality of connecting portions may be provided only on the curved surface shell 23a or the end surface shell 23 b.
The connecting head 43 is connected to the fixing element 41 at a position away from the fixing arm 42, and the connecting head 43 is detachably connected in the connecting groove 232 by means of insertion. Alternatively, the connecting head 43 includes but is not limited to an L-shaped structure, for example, a T-shaped structure is also possible, and the number of the connecting heads 43 may be one or more. An elastic member 231 is disposed in the connecting slot 232, and after the connecting head 43 is inserted into the connecting slot 232, the connecting head 43 is pressed against the connecting slot 232 by the elastic member 231. The elastic member 231 includes, but is not limited to, a spring, a torsion spring, or a spring plate. Of course, the entire fixing member 41 may also be designed to have a zigzag structure, the connecting groove 232 is designed to be a straight groove, and the elastic member 231 is disposed at the notch of the straight groove. When the fixing member 41 is inserted into the connecting groove 232, the elastic member 231 is used to clamp the whole fixing member 41, and the protective casing can be detachably connected to the flexible protective layer 21, so that the connecting head 43 does not need to be separately disposed on the fixing member 41.
It can be understood that the connecting portion disposed in the protective shell is not limited to the above structural form, and the connecting portion may be designed in a structure manner such as a buckle, a pin, or a screw to achieve detachable connection between the flexible protective layer 21 and the protective shell. For example, a clamping groove is formed in the protective shell, and one end of the flexible protective layer 21 is connected with the clamping head, so that the flexible protective layer 21 is detachably connected with the protective shell in a buckling connection mode. For another example, a pin hole is formed in the protective shell, one end of the flexible protective layer 21 is connected to the ear seat, and the pin shaft penetrates through the pin hole and the ear seat, so that the flexible protective layer 21 and the protective shell can be detachably connected. Of course, according to different structural forms of the protective shell, more structural modes of the connecting portion capable of detachably connecting the flexible protective layer 21 can be selected.
As shown in fig. 9, in some embodiments, the structural form of the supporting member 23 is not limited to the structural form of the protective casing, and the supporting member 23 may be designed separately, so long as it can support the flexible protection layer 21. The support 23 is designed, for example, as an electromagnetic drive. Specifically, as shown in fig. 9, the supporting member 23 includes the magnetic member 50 and the carrier plate 60, the carrier plate 60 may be designed to have the same shape as the protective shell, and one end of the flexible protection layer 21 is connected to the carrier plate 60. The coil 61 is formed on the carrier plate 60 by means of pasting, etching or laser, and the magnetic element 50 is disposed at a position opposite to the coil 61. When a forward or reverse current is applied to the coil 61, the coil 61 generates a magnetic force to interact with the magnetic element 50 to move away from or close to the magnetic element 50, which also enables the support 23 to move relative to the retractable member 22. The magnetic member 50 includes, but is not limited to, a magnet, a magnetizing body, or a magnetic structure such as an energized coil.
It is understood that the positions of the magnetic element 50 and the carrier plate 60 can be interchanged, that is, the magnetic element 50 is designed to have the same shape as the protective shell, and one end of the flexible protection layer 21 is connected to the magnetic element 50. In order to ensure the moving directionality of the retractable member 22 and/or the supporting member 23, a guide rail structure may be further added at the position of the retractable member 22 and/or the supporting member 23, so that the retractable member 22 and/or the supporting member 23 move along the unfolding direction of the flexible display screen 11. The electromagnetic driving structure adopted by the supporting member 23 is also applicable to the retractable member 22, so that the retractable member 22 drives the retraction and release of the flexible protection layer 21 through the electromagnetic driving structure. Of course, the supporting member 23 may be designed as a reel-type structure as the retractable member 22, so that the reel can support the flexible protection layer 21.
According to the display screen protection device provided by the invention, the flexible protection layer 21 can be unfolded or folded on one side of the display surface of the display screen through the driving of the retractable part 22 and the supporting part 23, so that the effects of improving the impact resistance and the scratch resistance on the falling and daily scraping of the display screen are achieved. Particularly, for the roll-sliding display screen 10, the function of synchronously unfolding or folding the flexible protection layer 21 and the flexible display screen 11 can be realized. In addition, the detachable connection mode of the flexible protection layer 21 and the protection shell also enables the flexible protection layer 21 to be replaced quickly.
As shown in fig. 8, based on the same design concept of the present invention, the display screen protection device provided by the present invention is not only suitable for protecting the sliding display screen 10, but also suitable for protecting the common display screen 13. Specifically, as shown in fig. 8, the supporting member 23 is designed as two supporting members 23 in a split type, and the two supporting members 23 are respectively disposed at two sides of the common display 13, so that the two supporting members 23 do not interfere with the common display 13 when moving away from or close to the retractable member 22. When the common display screen 13 is not needed to be used, the flexible protective layer 21 can be unfolded by the display screen protection device provided by the invention to shield the common display screen 13, so as to prevent the common display screen 13 from being scratched, impacted or dust or other adverse effects.
As shown in fig. 8, the retractable member 22 and the supporting member 23 can be one of the reel, the driving motor or the electromagnetic driving structure in the above embodiments. For example, the winding and unwinding members 22 and the supporting member 23 can be both reels. The length of the reel of the retractable member 22 is the same as the length of one side of the common display 13, and the reels of the two support members 23 are respectively arranged on two sides of the reel of the retractable member 22. The overall width of the flexible cover 21 is greater than or equal to the width of the normal display 13 at the side, and the flexible cover 21 is wider only at the position of the reel of the two supports 23, so that the flexible cover 21 can be conveniently connected with the reel of the supports 23.
When the reels of the two supporting pieces 23 move in the direction away from the retractable piece 22, the flexible protective layer 21 is unfolded on the display surface side of the ordinary display 13 to protect the ordinary display 13 and improve the scratch resistance and impact resistance of the ordinary display 13. When the flexible protective layer 21 is not needed, the reels of the two supporting members 23 move in the direction close to the winding and unwinding member 22, the flexible protective layer 21 is rewound on the reels of the winding and unwinding member 22, and meanwhile, the reels of the two supporting members 23 move to be located on the same axis as the reels of the winding and unwinding member 22, so that the structure of the display screen protection device in the winding state is more compact.
As shown in fig. 10, the flexible protection layer 21 is a single-layer film 211, and the material of the film 211 may be one of transparent polyimide (CPI), thermoplastic polyurethane elastomer rubber (TPU), or ultra-thin glass (UTG). The film 211 made of these materials has the characteristics of good light transmittance and strong fatigue resistance. When the flexible protection layer 21 is a single-layer film 211, the film 211 made of CPI or TPU is preferred.
As shown in fig. 11 and 12, the flexible protection layer 21 may also be designed as a multi-layer film 211, such as a two-layer film 211 shown in fig. 11 or a three-layer film 211 shown in fig. 12. When the flexible protection layer 21 is two layers of films 211, the two layers of films 211 are bonded by the optical adhesive layer 212. The material of the film 211 may also be one of CPI, TPU, or UTG, and the materials of the two layers of film 211 may be the same or different. When the flexible protection layer 21 is a three-layer film 211, the three-layer film 211 is bonded by the optical adhesive layer 212. The material of the film 211 may also be one of CPI, TPU, or UTG, and the materials of the three layers of the film 211 may be the same or different.
It can be understood that the flexible protection layer 21 with different hardness degrees is selected according to different display screen materials, and therefore the material and the number of layers of the flexible protection layer 21 are not limited in the present invention. For example, the material of the flexible protection layer 21 may also be high Polymer Polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), or the like. The number of layers of the film material 211 of the flexible protection layer 21 may also be designed to be four or more. In order to facilitate the unfolding or folding action of the flexible protective layer 21, the thickness of the whole flexible protective layer 21 is preferably controlled to be 50-300 μm.
As shown in fig. 1 to 3, in order to avoid friction of the flexible protective layer 21 against the display screen, a gap 30 is designed between the flexible protective layer 21 and the display screen. Alternatively, the size of the gap may be designed to be 10-500 microns. In addition, in order to prevent static electricity that may occur during the unfolding or folding of the flexible protective layer 21, an antistatic transparent coating layer is coated on the surface of the flexible protective layer 21 facing the display screen. Alternatively, an antistatic light-transmitting coating is coated on the surface of the display screen facing the flexible protective layer 21. Alternatively, the opposite surfaces of the flexible protective layer 21 and the display screen are coated with antistatic light-transmitting coatings.
It will be appreciated that the gap 30 need not necessarily be designed between the flexible protective layer 21 and the display screen, depending on the size of the display screen and the application. For example, the flexible protection layer 21 may be directly attached to the display screen without affecting the unfolding or folding action of the flexible protection layer 21.
Example 2:
the invention also provides display equipment which comprises a shell and the display screen protection device in the embodiment. The display device includes but is not limited to devices such as a mobile phone, a display, a screen, a stop board, an advertisement, a scrolling screen, and the like, and according to different structural forms adopted by the retractable member 22, a corresponding reel mounting seat, a motor mounting part, a powered coil fixing part or a magnetic member fixing part and other adapting structures are arranged in a shell of the display device, so that the retractable member 22 is mounted in the shell.
For a display screen with a roll-sliding type, the supporting member 23 may be directly connected to one end of the display screen, so that the supporting member 23 moves along with the sliding of the display screen, thereby unfolding or folding the flexible protection layer 21. For a fixed display screen, a slider, a rail, or a bracket may be provided for mounting the support 23.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
