Description

Technical Field

[0001] The present invention relates to the field of electronic devices, and in particular to an automatic zooming display screen applicable to all electronic devices. Background Art

[0002] Common electronic devices (e.g., smartwatches, smart bands, mobile phones, tablets, laptops, and car displays) are all equipped with displays. Typically, these displays are fixed in size and cannot be scaled. However, with increasing user demand, display scaling mechanisms have emerged on mobile phones, typically achieved through folding or rolling screens. However, these mechanisms rely on the bending or rolling of the screen itself and are currently not applicable to all electronic devices. They are particularly challenging to implement in devices with smaller displays.

[0003] Take smartwatches, for example. Currently, smartwatches on the market have two dial styles: square and round. Due to their rich functionality and display content, smartwatches require larger dials to meet user needs. However, wearing a watch with a large dial for extended periods can cause wrist discomfort, especially when bending the wrist. Smart bracelets that offer comfort often have screens that are too small to meet user expectations. However, existing folding and rolling screen designs are extremely difficult to apply to smartwatch displays.

[0004] Therefore, it is necessary to provide an automatic zooming display screen that can be applied to all electronic devices, especially electronic devices with extremely small screens, so as to achieve free zooming of the display screen, thereby improving the portability and user experience of the electronic devices. Summary of the Invention

[0005] The object of the present invention is to provide an automatic zooming display screen that can be applied to all electronic devices to achieve free zooming of the display screen and improve the portability and user experience of the electronic devices.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: to provide an automatic zooming display screen, which includes a main screen, at least one group of extended screens and a driving component; wherein, the main screen can be set to be raised and lowered; the extended screens are installed below the main screen, and each of the extended screens includes at least one sub-screen, and the sub-screens are movably set; the driving component is respectively connected to the main screen and each of the sub-screens, and is used to drive the main screen to rise and fall and drive each of the sub-screens to move back and forth, so that the sub-screens are spliced ​​at the edge of the main screen or folded below the main screen.

[0007] Preferably, when there are at least two groups of extended screens, the sub-screens of each group of extended screens are movably arranged along at least two intersecting directions, and the driving component drives the sub-screens of each group of extended screens to move back and forth synchronously to achieve expansion and folding in at least two directions, thereby obtaining a larger display screen and improving the user's experience of use, and having a smaller volume after folding, thereby improving portability and / or comfort of long-term wearing.

[0008] Preferably, the automatic zooming display screen is provided with two groups of extended screens, the sub-screens of the two groups of extended screens are movably arranged along two perpendicular directions, and the driving component drives the sub-screens of the two groups of extended screens to move back and forth synchronously along two perpendicular directions to achieve expansion or contraction.

[0009] Preferably, each of the extended screens includes two sub-screens, which are arranged to be spaced apart in the same direction. The driving component drives the two sub-screens of each extended screen to move synchronously in opposite directions to be spliced ​​to the edge of the main screen, or to move synchronously toward each other to be folded under the main screen.

[0010] Preferably, the driving assembly includes a driving member, a connecting member and at least one group of connecting rod assemblies, each of the connecting rod assemblies includes at least one connecting rod, the driving member is fixedly connected to the connecting member, the connecting member is connected to the main screen, the two ends of the connecting rod are respectively pivoted to the connecting member and the sub-screen, the driving member is used to drive the connecting member to rotate back and forth, the main screen is driven to rise and fall and the connecting rod is driven to extend and retract through the connecting member, and the sub-screen is driven to move back and forth by the connecting rod.

[0011] Preferably, the automatic zooming display screen further comprises a controller, which is electrically connected to the driving member. The controller controls the driving member to rotate forward and reverse, thereby driving the connecting member to rotate back and forth to achieve zooming in or out of the display screen.

[0012] Preferably, the connecting rod includes a first connecting arm and a second connecting arm in a curved shape. The first connecting arm is pivotally connected to one end of the connecting member, and the second connecting arm protrudes toward the other end of the connecting member and is pivotally connected to the split screen. The curved configuration of the connecting rod reduces the space occupied by the connecting rod after installation, and allows the connecting rod to extend and retract a longer distance with a relatively small pivot angle of the connecting member. The space occupied by the connecting rod during extension and retraction is small, thereby making the automatic zooming display screen compact and compact.

[0013] Preferably, when each of the extended screens includes two split screens, each of the connecting rod assemblies includes two connecting rods, one end of each connecting rod being pivotally connected to opposite ends of the connecting member, and the other ends of the two connecting rods extending in opposite directions and being pivotally connected to the split screens. The two connecting rods are arranged so that their pivotal positions and extending directions are opposite to each other, thereby reducing the space occupied by the two connecting rods after installation. Furthermore, a relatively small pivot angle of the connecting member can drive the two connecting rods to synchronously extend and retract a relatively long distance. The space occupied by the two connecting rods during extension and retraction is reduced, thereby making the structure of the automatic zooming display screen compact and reduced in size.

[0014] Preferably, both of the connecting rods are bent, and are centrally symmetrically arranged with respect to the rotation center of the connecting member, so that the space occupied by the two connecting rods after installation is smaller.

[0015] Preferably, a connecting shaft is fixed on the main screen, and the end of the connecting shaft cooperates with the connecting member through an inclined surface.

[0016] Preferably, a connecting shaft and a positioning shaft are fixed on the main screen, and the connecting shaft can be raised and lowered through the connecting member, and the connecting member drives the main screen to rotate through the connecting shaft, and the main screen is kept in a raised position or a lowered position through the abutment of the connecting shaft and / or the positioning shaft.

[0017] Preferably, the automatic zooming display screen also includes a positioning member, which is installed below the main screen and has a support surface and a positioning groove recessed in the support surface; when the connecting shaft and / or the positioning shaft abuts against the support surface, the main screen is maintained in the raised position, and when the main screen is rotated until the connecting shaft and / or the positioning shaft falls into the positioning groove, the main screen is maintained in the lowered position.

[0018] Preferably, the positioning member is installed between the connecting member and the main screen, and when the main screen rotates, the positioning shaft can detachably abut against the supporting surface or the positioning groove to keep the main screen in a raised position or a lowered position.

[0019] Preferably, two spaced-apart positioning shafts are fixed on the main screen, and the distances between the two positioning shafts and the rotation center of the main screen are different. The positioning member is provided with two spaced-apart positioning grooves, and the distances between the two positioning grooves and the rotation center of the positioning member correspond to the distances between the two positioning shafts and the rotation center of the main screen. When the two positioning shafts are in contact with the abutting surface, the main screen is maintained in the raised position. When the main screen is rotated until the two positioning shafts fall into the two positioning grooves respectively, the main screen is maintained in the lowered position.

[0020] Preferably, an inner wall of the positioning groove is provided with an abutting inclined surface, and when the main screen rotates, the main screen can be driven to rise through the cooperation of the abutting inclined surface with the connecting shaft and / or the positioning shaft.

[0021] Preferably, two spaced-apart connecting shafts are fixed on the main screen, and the two connecting shafts are movably passed through the connecting member. The connecting member drives the main screen to rotate through the connecting shafts. When the main screen rotates until the positioning shaft falls into the positioning groove, the connecting shaft moves downward along the connecting member.

[0022] Preferably, the automatic zooming display screen also includes a guide component, which includes a slide rail and a sliding member. The slide rail is fixed below the main screen, and the sliding member is slidably connected to the slide rail and fixed to the split screen, thereby guiding the sliding of the split screen and making the sliding of the split screen more labor-saving.

[0023] Preferably, the sliding member includes a sliding rod and an abutment block and a connecting column provided on the sliding rod, the connecting column passes through the sliding rail and is fixed to the split screen, and when the sliding member slides, the abutment block and / or the connecting column abut against the sliding rail to achieve positioning, or the abutment block and / or the connecting column abut against the sliding rod of another sliding member to achieve positioning.

[0024] Preferably, each of the guide assemblies includes two sliding members, which are respectively slidably connected to the slide rails, and the abutment blocks of the two sliding members are located at one end away from each other, and the connecting columns of the two sliding members respectively pass through the slide rails and are fixed to the two split screens. When the two split screens slide toward each other, the sliding rods of the two sliding members and the abutment blocks can abut against each other to achieve limiting.

[0025] Compared with the prior art, the automatic zooming display screen of the present invention has at least one group of extended screens and a driving component disposed below the main screen, and each group of extended screens includes at least one movably disposed sub-screen, the driving component being connected to the main screen and each sub-screen respectively, and being used to drive the main screen to rise and fall and to drive each sub-screen to move back and forth, so that each sub-screen is spliced ​​at the edge of the main screen or folded below the main screen. Therefore, the user can control the size of the display screen according to usage requirements, and effectively improve the user's portability and / or comfort of long-term wearing without affecting the user's large-screen experience. At the same time, the display screen can be enlarged or reduced by raising and lowering the main screen and moving each sub-screen, which also brings a cool feeling to the user and further enhances the sense of use. In addition, the zooming of the display screen does not depend on the bending or winding of the screen itself. Therefore, the automatic zooming display screen can be applied to any electronic device, especially to electronic devices with smaller screens, thus having wider applicability and inclusiveness.

[0045] The directions or positional relationships indicated in the present invention, such as up, down, left, right, front, and back, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the technical solutions of this application and / or simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this application. Terms such as first and second are used solely to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0046] Combine Figures 1-19As shown, the automatic zooming display screen 100 provided by the present invention is applicable to all electronic devices. The electronic devices may be various handheld devices (e.g., mobile phones, tablet computers, etc.), computing devices (e.g., laptop computers, etc.), vehicle-mounted devices (e.g., vehicle-mounted display screens, etc.), wearable devices (e.g., smart watches, smart bracelets, etc.), and various forms of user equipment (UE), mobile stations (MS), terminal devices, etc., which are not specifically limited in this application.

[0047] Continue to combine Figures 1-19 As shown, in one embodiment of the present invention, the automatic zooming display screen 100 includes a main screen 110, at least one set of extended screens 120, and a drive assembly 130. The main screen 110 is configured to be liftable at least in the vertical direction. The extended screens 120 are installed below the main screen 110, and each extended screen 120 includes at least one sub-screen 121, which is movably configured in the horizontal direction. In this embodiment, the vertical direction is the thickness direction of the automatic zooming display screen 100, and the horizontal direction is a direction perpendicular to the thickness direction of the automatic zooming display screen 100, or a direction parallel to the plane of the main screen 110. The drive assembly 130 is connected to the main screen 110 and each sub-screen 121, respectively, and is used to drive the main screen 110 to rise and fall and drive each sub-screen 121 to move back and forth synchronously, so that the sub-screens 121 are spliced ​​to the edge of the main screen 110 or folded below the main screen 110, thereby achieving zooming in or out of the display screen 100.

[0048] The following combination Figure 2-Figure 3 As shown, in a preferred embodiment of the present invention, the automatic zooming display screen 100 is provided with at least two groups of extended screens 120, and the sub-screens 121 of each group of extended screens 120 are movably arranged along at least two intersecting horizontal directions. In addition, the driving component 130 is respectively connected to the sub-screens 121 of each group of extended screens 120, and the driving component 130 drives the sub-screens 121 of each group of extended screens 120 to move back and forth synchronously to achieve expansion or folding in at least two horizontal directions. Therefore, after expansion, a larger display screen 100 can be obtained to meet the user's experience of a large screen, and after folding, it has a smaller volume, thereby improving portability and / or comfort for long-term wearing.

[0049] Continue to combine Figure 1-Figure 3As shown, in a specific embodiment of the present invention, the automatic zooming display screen 100 is provided with a group of extended screens 120, and the sub-screens 121 of the group of extended screens 120 are arranged to slide along the same horizontal direction. The driving component 130 is simultaneously connected to each sub-screen 121 of the extended screen 120, and is used to drive each sub-screen 121 to slide back and forth along the same horizontal direction, thereby achieving expansion or contraction in a horizontal direction. For example, Figure 2 In the illustrated embodiment, the split screens 121 are all slidably arranged along the X-axis. When the driving assembly 130 drives the split screens 121 to slide outward along the X-axis, the split screens 121 can be spliced ​​to the ends of the main screen 110 in the upward direction of the X-axis. When the driving assembly 130 drives the split screens 121 to slide inward along the X-axis, the split screens 121 can be folded under the main screen 110. Figure 1 shown.

[0050] It is understandable that it is feasible to slide the two split screens 121 along the Y axis, or to slide the two split screens 121 along any direction between the X axis and the Y axis.

[0051] Recombination Figure 2-Figure 3 As shown, in another specific embodiment of the present invention, the automatic zooming display screen 100 is provided with two sets of extended screens 120. The sub-screens 121 of the two sets of extended screens 120 are preferably arranged to slide along two perpendicular horizontal directions. The driving assembly 130 is simultaneously connected to each sub-screen 121 of the two sets of extended screens 120, thereby driving each sub-screen 121 of the two sets of extended screens 120 to synchronously move back and forth along two perpendicular horizontal directions to achieve expansion or contraction. For example, the sub-screens 121 of one set of extended screens 120 are arranged to slide along the X-axis, while the sub-screens 121 of the other set of extended screens 120 are arranged to slide along the Y-axis. In this way, the driving assembly 130 simultaneously drives the sub-screens 121 of the two sets of extended screens 120 to move, thereby achieving expansion or contraction in the perpendicular X-axis and Y-axis directions. Of course, it is also feasible for the sub-screens 121 of the two sets of extended screens 120 to slide along any direction between the X-axis and the Y-axis.

[0052] Continue to combine Figure 1-Figure 3 As shown, in a preferred embodiment of the present invention, each group of extended screens 120 includes two sub-screens 121, and the two sub-screens 121 are arranged to slide at intervals along the same horizontal direction. Figure 2In the embodiment shown, the two sub-screens 121 are arranged to slide in a spaced relationship along the X-axis. Moreover, the shape of the inner edge of each sub-screen 121 corresponds to the shape of the two outer edges of the main screen 110. The driving assembly 130 drives the two sub-screens 121 to move synchronously in opposite directions to be spliced ​​to the two outer edges of the main screen 110, or drives the two sub-screens 121 to move synchronously toward each other to be folded under the main screen 110, as shown in FIG. Figure 1 shown.

[0053] Combine Figure 13 、 Figure 15 As shown, when the driving assembly 130 drives the two split screens 121 to slide in opposite directions along the X-axis, the main screen 110 is synchronously driven to descend until the two split screens 121 are spliced ​​at the two outer edges of the main screen 110 in the X-axis direction. The main screen 110 and the two split screens 121 are located in the same plane and are spliced ​​together to form a larger display screen 100, thereby achieving an enlargement of the display screen 100. When the driving assembly 130 drives the two split screens 121 to slide toward each other along the X-axis, the main screen 110 can be synchronously driven to ascend. When the inner edges of the two split screens 121 abut against each other, the two split screens 121 are retracted below the main screen 110, as shown in FIG. Figure 1-2 As shown, the main screen 110 and the sub-screen 121 are folded to achieve the reduction of the display screen 100.

[0054] Recombination Figures 1-19 As shown, in one embodiment of the present invention, the automatic zooming display screen 100 further includes a controller (not shown), which is electrically connected to the driving component 130. The controller is used to receive user instruction information and to control the action of the driving component 130 according to the instruction information, thereby driving the main screen 110 to rise and fall, and driving each sub-screen 121 to move back and forth in the horizontal direction to achieve zooming in or out of the display screen 100.

[0055] Furthermore, the automatic zooming display screen 100 also includes a device body, in which the controller, drive assembly 130, etc. are installed, and the extended screen 120 and the main screen 110 are sequentially arranged above the device body. Among them, the other components in the device body are flexibly arranged according to different electronic devices, and are all conventional methods familiar to those of ordinary skill in the art, and will not be described in detail. For example, when the automatic zooming display screen 100 is applied to a smart watch or smart bracelet, the device body is the watch body and watch strap.

[0056] The following combination Figure 2-Figure 5As shown, in one embodiment of the present invention, the driving assembly 130 includes a driving member 131, a connecting member 132 and at least one group of connecting rod assemblies. Each group of the connecting rod assemblies includes at least one connecting rod 133. Specifically, the number of connecting rods 133 contained in each group of the connecting rod assemblies corresponds to the number of split screens 121 possessed by each group of extended screens 120. The driving member 131 is fixedly connected to the connecting member 132 and is used to drive the connecting member 132 to rotate back and forth. The shape of the connecting member 132 is not specifically limited in this application. At the same time, the connecting member 132 is connected to the main screen 110, and the connecting member 132 is also pivotally connected to one end of the connecting rod 133, and the end of the connecting rod 133 away from the connecting member 132 is pivotally connected to the split screen 121. In this way, when the driving member 131 drives the connecting member 132 to rotate back and forth, the main screen 110 is driven to rise and fall through the connecting member 132, and the connecting member 132 drives the connecting rod 133 to extend and retract, and the connecting rod 133 drives the sub-screen 121 to move back and forth horizontally, so that the sub-screen 121 is spliced ​​to the edge of the main screen 110 or folded under the main screen 110.

[0057] In this embodiment, the driving member 131 is electrically connected to the controller, and the controller controls the driving member 131 to rotate forward or reverse, thereby driving the connecting member 132 to rotate forward or reverse, thereby driving the main screen 110 to rise and fall, and driving each sub-screen 121 to move back and forth in the horizontal direction, thereby realizing the enlargement or reduction of the display screen 100.

[0058] In a preferred embodiment, the drive member 131 is a reduction motor electrically connected to the controller. The controller controls the reduction motor to rotate forward or reverse according to user instructions, thereby zooming in or out of the display screen 100. This simplifies control and reduces production costs. Of course, other drive components may also be used for the drive member 131.

[0059] The following combination Figure 3-Figure 5 As shown, in one embodiment of the present invention, the connecting rod 133 includes a first connecting arm 1331 and a second connecting arm 1332, each of which is bent. The first connecting arm 1331 is pivotally connected to one end of the connecting member 132, and the second connecting arm 1332 protrudes toward the other end of the connecting member 132. The second connecting arm 1332 is pivotally connected to the split screen 121. The bent structure of the connecting rod 133 reduces the space occupied by the connecting rod 133 after installation, and the connecting member 132 can be pivoted at a small angle to extend and retract the connecting rod 133 over a long distance. The space occupied by the connecting rod 133 during extension and retraction is small, thereby making the automatic zooming display screen 100 compact and compact.

[0060] Continue to combine Figure 2-Figure 5As shown, in a preferred embodiment of the present invention, each of the extended screens 120 includes two split screens 121. Correspondingly, each of the connecting rod assemblies includes two connecting rods 133, which are pivotally connected to opposite ends of the connecting member 132, and the other ends of the two connecting rods 133 are bent and protruded in opposite directions, and then pivotally connected to the two split screens 121 at both ends. Figure 4-5 For example, the first connecting arms 1331 of the two connecting rods 133 of the connecting rod assembly are respectively pivotally connected to the two ends of the connecting member 132 in the X-axis direction. The second connecting arms 1332 of the two connecting rods 133 are respectively bent and protrude in opposite directions, and then are respectively pivotally connected to the two split screens 121. More specifically, with the center of the pivot axis of the connecting member 132 as a reference point, the first connecting arm 1331 of one of the connecting rods 133 is pivotally connected to the left end of the connecting member 132, and the second connecting arm 1332 thereof is bent and protrudes toward the right end of the connecting member 132 and is pivotally connected to the right split screen 121. That is, the second connecting arm 1332 thereof is bent and protrudes in the positive direction of the X-axis. Correspondingly, the first connecting arm 1331 of the other connecting rod 133 is pivotally connected to the right end of the connecting member 132, and its second connecting arm 1332 bends to protrude toward the left end of the connecting member 132 and pivotally connect to the left split screen 121. That is, after bending, its second connecting arm 1332 protrudes along the negative direction of the X-axis. Furthermore, the two connecting rods 133 are arranged symmetrically with respect to the center of the pivot axis of the connecting member 132. This structural arrangement not only reduces the space occupied by the two connecting rods 133 after installation, but also allows the connecting member 132 to pivot at a relatively small angle to drive the two connecting rods 133 to synchronously extend and retract a relatively long distance. The space occupied by the two connecting rods 133 during extension and retraction is small, thereby making the automatic zooming display screen 100 compact and compact.

[0061] Recombination Figure 2-Figure 5 As shown, in the present invention, the specific shape of the connecting member 132 is not specifically limited. The connecting member 132 can be a circular structure, a radial structure, etc., to facilitate the connection of multiple connecting rods 133. In a specific embodiment, since only one set of the connecting rod assembly is provided, and the set of connecting rod assemblies only includes two connecting rods 133, that is, the connecting member 132 only needs to pivotally connect two connecting rods 133. Therefore, the connecting member 132 is configured as a rod-shaped structure, and two connecting ends 1321 and 1322 protrude from both sides of its pivot portion, and the two connecting ends 1321 and 1322 protrude in opposite directions. Its pivot portion is fixedly connected to the output shaft of the driving member 131, and the center of the pivot portion is the center of its pivot axis. The first connecting arms 1331 of the two connecting rods 133 are pivotally connected to the ends of the two connecting ends 1321 and 1322 respectively. The rod-shaped structure of the connecting member 132 simplifies its structure and saves effort in driving. Of course, for the method of pivoting only two connecting rods 133 , even if the connecting member 132 is configured as a circular structure, it will not affect the pivoting and driving of the two connecting rods 133 .

[0062] It is understandable that for an embodiment in which two sets of expansion screens 120 are provided and four connecting rods 133 need to be pivotally connected, four connecting ends can be provided so that the four connecting ends are located in two perpendicular directions. Of course, it is also feasible to provide a circular connecting member 132 to pivotally connect the four connecting rods 133.

[0063] The following combination Figure 2-3 、 Figure 6-9 As shown, in one embodiment of the present invention, the automatic zooming display screen 100 further includes a guide component 140, which is installed below the main screen 110, and the split screens 121 of the extended screen 120 are respectively slidably connected to the guide component 140, and the guide component 140 guides the sliding of the split screens 121.

[0064] See Figure 3 As shown, in one embodiment, the automatic zooming display screen 100 includes two sets of guide assemblies 140. The two sets of guide assemblies 140 are arranged in parallel and located on either side of the drive assembly 130, and both extend along the X-axis. The two ends of each split screen 121 in the Y-axis direction are slidably connected to the two guide assemblies 140, thereby making the sliding of the split screen 121 smoother and more labor-saving.

[0065] Continue to combine Figure 3 、 Figure 6-9 As shown, in one embodiment, the guide assembly 140 includes a slide rail 141 and a slider 142. The slide rail 141 is fixed below the main screen 110 and extends along the X-axis. The slider 142 is slidably connected to the slide rail 141 and fixed to the bottom of the split screen 121. When the split screen 121 is pushed by the connecting rod 133 and moves horizontally, it drives the slider 142 to slide along the slide rail 141. The cooperation between the slide rail 141 and the slider 142 not only guides the movement of the split screen 121, but also reduces the effort required to move the split screen 121. Therefore, only a small driving force is required to move the split screen 121 and achieve expansion.

[0066] Continue to combine Figure 6-9As shown, in a preferred embodiment, the top surface of the slide rail 141 is provided with a slide groove 1411, and the slide groove 1411 extends along the axial direction of the slide rail 141. The sliding member 142 includes a slide rod 1421 and an abutment block 1422 and a connecting column 1423 provided on the slide rod 1421. The connecting column 1423 is protruded from the upper surface of the slide rod 1421, and the abutment block 1422 is protruded from the upper surface or lower surface of the slide rod 1421, thereby making the connecting column 1423 protrude from the abutment block 1422, or making the abutment block 1422 and the connecting column 1423 protrude in opposite directions. After installation, the slide rod 1421 can be slidably accommodated in the slide rail 141, and the connecting column 1423 slides through the slide groove 1411 and protrudes from the outside of the slide rail 141. The connecting column 1423 is fixedly connected to the split screen 121. Thus, when the split screen 121 translates, the connecting post 1423 drives the sliding member 142 to move along the slide rail 141, and the sliding member 142 and the slide rail 141 cooperate to achieve guidance. Then, the abutment block 1422 and / or the connecting post 1423 abut against the slide rail 141 to achieve position limiting, or the abutment block 1422 and / or the connecting post 1423 abut against the slide bar 1421 of another sliding member 142 to achieve position limiting.

[0067] Combine Figure 7 、 Figure 9 As shown, in a more preferred embodiment, each guide assembly 140 includes two sliding members 142, and the two sliding members 142 are respectively slidably connected in the slide rail 141, and the abutment blocks 1422 of the two are located at ends away from each other, and the abutment blocks 1422 of the two protrude in opposite directions. Specifically, the abutment block 1422 of one sliding member 142 is provided on the upper surface of one end of the slide rod 1421 and protrudes upward, and the connecting column 1423 is protruded from the abutment block 1422; the abutment block 1422 of the other sliding member 142 is provided on the lower surface of one end of the slide rod 1421 and protrudes downward, and the connecting column 1423 is protruded from the upper surface of the slide rod 1421, that is, the abutment block 1422 and the connecting column 1423 of the sliding member 142 protrude in opposite directions. The slide rods 1421 of the two sliding members 142 are stacked up and down and can slide relative to each other (see Figure 9 ), and the contact blocks 1422 of the two are located at the ends away from each other, and the connecting posts 1423 of the two sliding members 142 slide through the sliding grooves 1411 and are fixed to the bottom of the two split screens 121. Figure 6 、 Figure 8 As shown, when the two connecting rods 133 push the two split screens 121 to slide in opposite directions, the two split screens 121 drive the two sliding members 142 to slide in opposite directions, as shown in FIG. Figure 6 Correspondingly, when the two connecting rods 133 pull the two split screens 121 to slide toward each other, the two split screens 121 respectively drive the two sliding members 142 to slide toward the middle of the slide rail 141, as shown in FIG. Figure 8As shown in the direction of the middle arrow, the two sliding members 142 are limited by the mutual abutment between the sliding rod 1421 and the abutting block 1422, thereby limiting the position of the two split screens 121.

[0068] It is understandable that the positioning is not limited to being achieved by the mutual abutment between the sliding rod 1421 and the abutment block 1422. For example, the positioning can also be achieved by the abutment between the sliding rod 1421 and the connecting column 1423.

[0069] In addition, for an embodiment in which the guide assembly 140 includes only one sliding member 142 , the limiting can be achieved by abutting the abutting block 1422 and / or the connecting column 1423 against the slide rail 141 , which is a conventional method in the art.

[0070] The following combination Figure 10-12 、 Figure 16-17 As shown, in one embodiment of the present invention, a connecting shaft 111 is fixed to the bottom of the main screen 110, and the end of the connecting shaft 111 cooperates with the connecting member 132 through an inclined surface. In this way, when the driving member 131 drives the connecting member 132 to rotate, the inclined surface drives the connecting shaft 111 to rise and fall, thereby driving the main screen 110 to rise and fall. More specifically, two connecting shafts 111 are fixed to the bottom of the main screen 110, and the two connecting shafts 111 are symmetrically arranged along the center of the main screen 110, and the end of each connecting shaft 111 is provided with a first inclined surface. Correspondingly, a second inclined surface that cooperates with the first inclined surface is provided on the two connecting ends 1321 and 1322 of the connecting member 132. When installed, the center of the main screen 110 coincides with the center of the pivot axis of the connecting member 132, and the first inclined surface of the connecting shaft 111 abuts against the second inclined surface. In this way, when the connecting member 132 rotates, the main screen 110 can be pushed through the interaction between the first inclined surface and the second inclined surface, thereby achieving the lifting and lowering of the main screen 110.

[0071] It is understandable that the connection method between the main screen 110 and the connecting member 132 is not limited to the above embodiment. Other structures can also be used to realize that the connecting member 132 drives the main screen 110 to rise and fall.

[0072] Continue to combine Figure 10-12 、 Figure 16-17 As shown, in a preferred embodiment of the present invention, a connecting shaft 111 and a positioning shaft 112 are fixed to the bottom of the main screen 110. The connecting shaft 111 is lifted and lowered through the connecting member 132. The connecting member 132 drives the main screen 110 to rotate via the connecting shaft 111. Then, the main screen 110 is kept in an elevated or lowered position through the contact between the connecting shaft 111 and / or the positioning shaft 112, thereby achieving the lifting and lowering of the main screen 110.

[0073] See Figure 10As shown, in a specific embodiment, two connecting shafts 111 and two positioning shafts 112 are provided. The two connecting shafts 111 are arranged along a straight line passing through the center of the main screen 110, and the two positioning shafts 112 are arranged along another straight line passing through the center of the main screen 110. The two straight lines are preferably perpendicular to each other, but are not limited to this. In addition, the distances L1 and L2 between the two positioning shafts 112 and the center of the main screen 110 are different. Figure 11-14 As shown, after the main screen 110 is installed, the two connecting shafts 111 are respectively inserted into the through holes 1323 and 1324 on the connecting ends 1321 and 1322 of the connecting member 132, and the connecting shafts 111 can slide up and down along the through holes 1323 and 1324, thereby realizing the lifting and lowering of the main screen 110, and the abutment of the two positioning shafts 112 to keep the main screen 110 in the raised position or lowered position, thereby realizing the lifting and lowering of the main screen 110.

[0074] Combine again below Figure 2-Figure 5 As shown, in this preferred embodiment, the automatic zooming display screen 100 further includes a positioning member 150. The positioning member 150 is installed between the connecting member 132 and the main screen 110, and the center of the positioning member 150 coincides with the center of the pivot axis of the connecting member 132. The positioning member 150 is provided with a support surface 151 and a positioning groove 152 recessed in the support surface 151. When the main screen 110 rotates, the positioning shaft 112 detachably abuts against the support surface 151 or the positioning groove 152, thereby maintaining the main screen 110 in a raised or lowered position.

[0075] See Figure 4-Figure 5 As shown, in a specific embodiment, the support surface 151 is annular and is provided at the edge of the positioning member 150. The support surface 151 can be Figure 4-5 , it can be composed of two spaced-apart circular rings as shown in , or it can be composed of a circle with a certain width, which is not specifically limited here. Two positioning grooves 152 are respectively recessed at both ends of the support surface 151 along a diameter direction of the positioning member 150, and one positioning groove 152 is recessed on the inner side wall of the support surface 151, and the other positioning groove 152 is recessed on the outer side wall of the support surface 151, thereby making the distances L1 and L2 between the two positioning grooves 152 and the center of the positioning member 150 different. Specifically, the distance L1 between the positioning groove 152 located on the outer side wall of the support surface 151 and the center of the positioning member 150 is greater than the distance L2 between the positioning groove 152 located on the inner side wall and the center of the positioning member 150, see Figure 5 As shown. Combined Figure 10 As shown, the distances L1 and L2 from the two positioning grooves 152 to the center of the positioning member 150 correspond to the distances L1 and L2 from the two positioning axes 112 to the center of the main screen 110 .

[0076] Combine Figure 11-12As shown, when the main screen 110 is in the initial position, the two positioning shafts 112 fixed thereon respectively abut against the support surface 151 and are located on the sides of the two positioning grooves 152, so that the two positioning shafts 112 and the two positioning grooves 152 are staggered, thereby keeping the main screen 110 in the raised position. Figure 18-19 As shown, when the connecting member 132 drives the main screen 110 to rotate a certain angle, for example, in a specific embodiment, the connecting member 132 drives the main screen 110 to rotate 180°, so that the two positioning shafts 112 rotate to positions corresponding to the two positioning grooves 152. At this time, the two positioning shafts 112 fall into the two positioning grooves 152 respectively, thereby keeping the main screen 110 in the lowered position.

[0077] Continue to combine Figure 4-5 、 Figure 18-19 As shown, more preferably, the inner wall of the positioning groove 152 is provided with an abutting inclined surface 1521. When the main screen 110 rotates, the main screen 110 can be driven to rise by the cooperation between the abutting inclined surface 1521 and the positioning shaft 112. In a specific embodiment, the positioning groove 152 has two abutting inclined surfaces 1521. The two abutting inclined surfaces 1521 are formed by the support surface 151 being recessed downward, so that the positioning groove 152 is generally V-shaped. Figure 4-5 Thus, when the main screen 110 is driven to rotate, the positioning shaft 112 may abut against the abutting inclined surface 1521, thereby driving the positioning shaft 112 to move upward, thereby driving the main screen 110 to rise to the initial position.

[0078] It is understood that locking the position of the main screen 110 is not limited to the cooperation between the positioning shaft 112 and the positioning member 150. In other embodiments, the positioning member 150 can also be installed below the connecting member 132, and a support surface 151 and a positioning groove 152 can be provided to directly cooperate with the connecting shaft 111, which can also maintain the main screen 110 in the raised or lowered position.

[0079] Recombination Figures 1-19 As shown, in each of the above-described embodiments, the main screen 110 and the sub-screen 121 are independently arranged, that is, the two are two independent screens. However, it is not limited to the above-mentioned structure to achieve free scaling of the display screen 100. For example, in another preferred embodiment, the main screen 110 and the sub-screens 121 are flexible display screens with an integrated structure, and the sub-screens 121 can be folded under the main screen 110 or spliced ​​to the edge of the main screen 110 after unfolding to form a larger display screen. Among them, the arrangement of each sub-screen 121, the driving component 130, and the way it drives each sub-screen 121 to unfold or fold are the same as those in the above-mentioned embodiments and will not be repeated.

[0080] Combine again below Figures 1-19 As shown, the working principle and process of the automatic zoom display screen 100 of the present invention are explained.

[0081] See Figure 1 As shown, when the electronic device needs to be carried or worn, the automatic zooming display screen 100 can be in a folded state. That is, each sub-screen 121 is folded below the main screen 110, making the display screen 100 smaller in size, improving the user's portability and comfort when wearing it for a long time.

[0082] See Figure 11-12 As shown, in Figure 1 In the state shown, the two positioning shafts 112 at the bottom of the main screen 110 respectively abut against the support surface 151 of the positioning member 150, and the two positioning shafts 112 are located on the sides of the two positioning grooves 152 and staggered with the positioning grooves 152, keeping the main screen 110 in the raised position.

[0083] See Figure 15 、 Figure 17 As shown, when the user needs to use a large screen, the automatic zoom display screen 100 can be transformed into an expanded state. Specifically, when the controller receives the user's instruction signal, it controls the driving member 131 to operate, and the driving member 131 drives the connecting member 132 to rotate. Figure 2 As shown, in one embodiment, the driving member 131 drives the connecting member 132 in a counterclockwise direction (eg Figure 2 The connecting member 132 rotates in the direction indicated by the arrow in the middle, and the main screen 110 rotates in a synchronous counterclockwise direction via the two connecting shafts 111. Simultaneously, the connecting member 132 drives the two connecting rods 133 to rotate in a synchronous counterclockwise direction, causing the two connecting rods 133 to extend. The two connecting rods 133 respectively push the two split screens 121 on the left and right sides to slide along the guide assembly 140, causing the two split screens 121 to gradually unfold.

[0084] Combine Figures 15-19 As shown, when the driving member 131 drives the connecting member 132 to rotate a certain angle, in this embodiment, after the driving connecting member 132 rotates 180°, the two connecting rods 133 extend to the maximum length and push the two split screens 121 to the maximum distance on the left and right sides. At this time, the two split screens 121 are just located at the left and right edge positions of the main screen 110. In addition, at this time, the main screen 110 is driven to rotate 180°, so that the two positioning shafts 112 at the bottom thereof rotate to positions corresponding to the two positioning grooves 152 of the positioning member 150. After losing support, the two positioning shafts 112 fall into the two positioning grooves 152. During this process, the two connecting shafts 111 slide along the through holes 1323 and 1324 on the connecting member 132, so that the main screen 110 is smoothly lowered to a position flush with the two split screens 121, as shown in FIG. Figure 15 The main screen 110 and the two sub-screens 121 are spliced ​​together to form a larger display screen 100, satisfying the user's large-screen experience.

[0085] The following combination Figure 17-19 As shown, when the display screen 100 needs to be folded again, the controller controls the driving member 131 to drive the connecting member 132 to rotate in the opposite direction according to the user's instruction signal. In this embodiment, the driving member 131 drives the connecting member 132 to rotate in the clockwise direction (as shown in FIG. Figure 17 During this process, the connecting member 132 drives the main screen 110 to rotate synchronously in the clockwise direction through the two connecting shafts 111. At this time, the bottom end of the positioning shaft 112 abuts against the abutting inclined surface 1521 (see Figure 19 As shown, the main screen 110 is driven upward by the cooperation of the abutting inclined surface 1521 and the positioning shaft 112. At the same time, the connecting member 132 drives the two connecting rods 133 to rotate synchronously in a clockwise direction, causing the two connecting rods 133 to retract. The two connecting rods 133 pull the two sub-screens 121 on the left and right sides to slide toward each other along the guide assembly 140, causing the two sub-screens 121 to gradually retract inward.

[0086] Combine Figure 1-2 、 Figure 11-12 As shown, when the main screen 110 rotates 180 degrees again, the two sub-screens 121 slide inwards until they abut against each other and are in a folded state (see Figure 2 ), at this time, the two positioning shafts 112 at the bottom of the main screen 110 again abut against the support surface 151 of the positioning member 150, keeping the main screen 110 in the raised position, so that the main screen 110 and the two sub-screens 121 are in a folded state, as shown in FIG. Figure 1-2 As shown, it has a smaller size, better portability and comfort for long-term wearing.

[0087] The automatic zooming display screen 100 in the present application provides the user with a cool usage effect through the change between zooming in and zooming out during the above-mentioned free selection of zooming, thereby further enhancing the user experience.

[0088] In summary, the automatic zooming display screen 100 of the present invention has at least one set of extended screens 120 and a drive assembly 130 disposed below the main screen 110. Each set of extended screens 120 includes at least one movably disposed sub-screen 121. The drive assembly 130 is connected to the main screen 110 and each sub-screen 121, respectively, and is used to drive the main screen 110 up and down and to drive each sub-screen 121 to move back and forth, so that each sub-screen 121 is spliced ​​to the edge of the main screen 110 or retracted below the main screen 110. Therefore, the user can control the size of the display screen 100 according to usage requirements, effectively improving the user's portability and / or comfort for long-term wearing without affecting the user's large-screen experience. At the same time, the display screen 100 can be enlarged or reduced by raising and lowering the main screen 110 and moving the sub-screens 121, which also brings a cool feeling to the user and further enhances the user experience. In addition, the zooming of the display screen does not depend on the bending or rolling of the screen itself. Therefore, the automatic zooming display screen 100 of the present invention is applicable to any electronic device, especially to electronic devices with smaller screens, thus having wider applicability and inclusiveness.

[0089] The structures of other parts of the display screen 100 involved in the present invention are conventional structures well known to those skilled in the art, and will not be described in detail here.

[0090] The above disclosure is only the preferred embodiment of the present invention and cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope of the present invention.
