[0001] The present application belongs to the technical field of communication equipment, and specifically relates to an electronic device. Background Art

[0002] With the improvement of user demand and the development of technology, the screens of electronic devices are getting bigger and bigger. Electronic devices equipped with flexible display screens can take into account the large screen demand and the portability of electronic devices, and thus are gradually favored by users.

[0003] In order to support the flexible display screen, the electronic device involved in the related art adopts two comb-tooth structures that can move relatively. However, the two comb-tooth structures that cooperate with each other have serious friction when the flexible display screen is unfolded or retracted, which will cause abnormal noise, which will undoubtedly affect the user's use. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem of abnormal noise in current electronic devices.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] An embodiment of the present application provides an electronic device, including a first body, a second body, a movable support, a lifting support, and a flexible display screen;

[0007] The first body and the second body are movably connected, one end of the flexible display screen is connected to the first body, and the other end of the flexible display screen is connected to the second body;

[0008] The lifting support member is movably disposed on the first body, and the movable support member is disposed on the second body;

[0009] When the electronic device is in the unfolded state, the movable support member moves to the first position, the lifting support member rises to the first height, and both the movable support member and the lifting support member abut against the flexible display screen; when the electronic device is in the folded state, the movable support member moves to the second position, the lifting support member drops to the second height, the movable support member covers the lifting support member, and the movable support member abuts against the flexible display screen.

[0010] In the embodiment of the present application, the lifting support member is movably arranged on the first body, the mobile support member is arranged on the second body, and the second body is movable relative to the first body, wherein the moving direction of the lifting support member intersects with the moving direction of the mobile support member, and the mobile support member drives the lifting support member to move through the transmission teeth of the transmission mechanism, and the lifting support member can support the flexible display screen together with the mobile support member through its own lifting, and can also avoid the mobile support member so that the mobile support member can retract and cover at least a part of the lifting support member. It can be seen that the embodiment of the present application can support the flexible display screen together through the mobile support member and the lifting support member when the electronic device is unfolded, thereby providing a better support effect. At the same time, the movement of the mobile support member and the lifting support member does not interfere with each other, so as to alleviate the friction between the two, thereby solving the problem of abnormal noise in the electronic device in the related art.

DETAILED DESCRIPTION

[0057] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0058] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0059] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0060] refer to Figures 1 to 60 The embodiment of the present application discloses an electronic device, including a first body 100, a second body 800, a movable support member 200, a lifting support member 300, a transmission mechanism 500 and a flexible display screen 400.

[0061] The first body 100 and the second body 800 are movably connected, that is, the second body 800 can move relative to the first body 100, one end of the flexible display screen 400 is connected to the first body 100, and the other end of the flexible display screen 400 is connected to the second body 800. When the first body 100 and the second body 800 move relative to each other, the flexible display screen 400 can slide relative to the second body 800, so that the area of ​​the part of the flexible display screen 400 located on the same side of the electronic device changes, thereby changing the display area of ​​the electronic device.

[0062] The lifting support member 300 is movably disposed on the first body 100, that is, the lifting support member 300 can move relative to the first body 100, and the movable support member 200 is disposed on the second body 800. Optionally, the lifting support member 300 can move along the thickness direction of the electronic device, so that the height of the lifting support member 300 changes; the movable support member 200 is fixedly disposed on the second body 800, and the two can move synchronously, and the moving direction of the two can be the width direction of the electronic device.

[0063] The transmission mechanism 500 is disposed on the first body 100 , and the transmission mechanism 500 includes a transmission tooth 501 . When the movable support member 200 is connected to the transmission mechanism 501 , the movable support member 200 drives the lifting support member 300 to move via the transmission tooth 501 .

[0064] When the electronic device is in the unfolded state, the movable support member 200 moves to the first position, the lifting support member 300 rises to the first height, and the movable support member 200 and the lifting support member 300 both abut against the flexible display screen 400, thereby jointly supporting the flexible display screen 400. At this time, the display area of ​​the flexible display screen 400 is large, which is convenient for viewing the displayed content, and when the user performs a touch operation, the rigidity of the flexible display screen 400 is large, which is beneficial to improving the user experience; when the electronic device is in the folded state, the movable support member 200 moves to the second position, the lifting support member 300 drops to the second height, the movable support member 200 covers the lifting support member 300, and the movable support member 200 abuts against the flexible display screen 400. At this time, the electronic device is small in size, which is convenient for users to carry, and the display area of ​​the flexible display screen 400 is small, and the support requirements of the flexible display screen 400 can be met only by the movable support member 200.

[0065] In the embodiment of the present application, the lifting support member 300 is movably arranged on the first body 100, the mobile support member 200 is arranged on the second body 800, and the second body 800 is movable relative to the first body 100, wherein the moving direction of the lifting support member 300 intersects with the moving direction of the mobile support member 200, and the mobile support member 200 drives the lifting support member 300 to move through the transmission teeth 501 of the transmission mechanism 500, and the lifting support member 300 can support the flexible display screen 400 together with the mobile support member 200 through its own lifting, and can also avoid the mobile support member 200, so that the mobile support member 200 retracts and covers at least a part of the lifting support member 300. It can be seen that the embodiment of the present application can support the flexible display screen 400 together through the mobile support member 200 and the lifting support member 300 when the electronic device is unfolded, thereby providing a better supporting effect. At the same time, the movement of the mobile support member 200 and the lifting support member 300 does not interfere with each other, so as to alleviate the friction between the two, thereby solving the problem of abnormal noise in the electronic device in the related art.

[0066] like Figures 1 to 34As shown, in an optional embodiment, the transmission mechanism 500 includes a linkage rod 510, which is rotatably arranged on the first body 100, and the linkage rod 510 is provided with an eccentric transmission part 511 and a transmission tooth 501, and the eccentric transmission part 511 and the transmission tooth 501 are arranged at intervals, that is, the linkage rod 510 is a camshaft provided with a transmission tooth 501, and the eccentric transmission part 511 can contact with the lifting support member 300. When the moving support member 200 is connected to the linkage rod 510, the moving support member 200 drives the linkage rod 510 to rotate through the transmission tooth 501, and the linkage rod 510 drives the linkage rod 510 to rotate through the eccentric transmission part 511. The eccentric transmission part 511 drives the lifting support member 300 to move. When the end of the eccentric transmission part 511 away from the rotation axis of the linkage rod 510 approaches the lifting support member 300, the eccentric transmission part 511 lifts the lifting support member 300 so that the lifting support member 300 is flush with the moving support member 200 to jointly support the flexible display screen 400. When the end of the eccentric transmission part 511 away from the rotation axis of the linkage rod 510 is away from the lifting support member 300, the eccentric transmission part 511 no longer applies a force to the lifting support member 300, and the lifting support member 300 can descend under the action of its own gravity. The structure of this transmission mechanism 500 is relatively simple, and the transmission chain is short, and the transmission efficiency is high. When the electronic device is in a folded state, the end of the eccentric transmission part 511 away from the rotation axis of the linkage rod 510 is at the same height as the linkage rod 510, thereby reducing the space of the eccentric transmission part 511 in the thickness direction of the electronic device, so as to make the electronic device thinner, thereby improving the user experience.

[0067] Optionally, the number of the eccentric transmission parts 511 can be one, in which case the supporting force of the eccentric transmission parts 511 on the lifting support member 300 is relatively concentrated, which is easy to damage the lifting support member 300. In another embodiment, the number of the eccentric transmission parts 511 is at least two, and each eccentric transmission part 511 is arranged at intervals along the extension direction of the linkage rod 510, and each eccentric transmission part 511 is in contact with the lifting support member 300, thereby dispersing the supporting force of the eccentric transmission part 511 on the lifting support member 300, and can increase the supporting area between the eccentric transmission part 511 and the lifting support member 300, which can not only protect the lifting support member 300, but also improve the stability of the lifting support member 300.

[0068] An elastic layer may be provided on the mobile support 200, and the elastic layer has a certain elasticity. When the elastic layer contacts the transmission tooth 501, the elastic layer can drive the linkage rod 510 to rotate through the transmission tooth 501. In another optional embodiment, the mobile support 200 is provided with a first rack 210, and the first rack 210 extends along the moving direction of the mobile support 200. The first rack 210 can be meshed with the transmission tooth 501, and the gear rack transmission mode has the characteristics of large power transmission and high transmission efficiency. When the first rack 210 is meshed with the transmission tooth 501, the first rack 210 drives the linkage rod 510 to rotate through the transmission tooth 501.

[0069] Optionally, the side of the first body 100 facing the movable support 200 is the first side, and the side of the first rack 210 facing the first body 100 is the second side. One of the first side and the second side is provided with a guide column 211, and the other is provided with a guide groove 120. The guide column 211 cooperates with the guide groove 120. During the movement of the first rack 210, the guide groove 120 provides guidance for the first rack 210.

[0070] Further optionally, one of the first surface and the second surface is provided with a sliding buckle 212, and the other is provided with a sliding groove 130, and the sliding buckle 212 and the sliding groove 130 are slidably matched to prevent the first rack 210 from detaching from the first body 100 along the thickness direction of the electronic device during the movement of the first rack 210.

[0071] In a further optional embodiment, the transmission mechanism 500 also includes a first gear 520, a second gear 530 and a third gear 540. The first gear 520 is rotatably disposed on the first body 100, and the second gear 530 is meshed with the first gear 520. Optionally, the first gear 520 can be a cylindrical gear, and the cylindrical gear has a first gear portion and a second gear portion arranged at intervals. The first gear portion is meshed with the first rack 210, and the second gear portion is meshed with the second gear 530 to avoid mutual influence between the first rack 210 and the second gear 530. The third gear 540 is meshed with the second gear 530, and the third gear 540 is meshed with the transmission tooth 501, and the axis of the second gear 530 intersects with the axis of the third gear 540. Optionally, the second gear 530 includes a first spur gear portion and a first bevel gear portion, the first spur gear portion is meshed with the second gear portion of the first gear 520, the third gear 540 includes a second spur gear portion and a second bevel gear portion, the first bevel gear portion is meshed with the second bevel gear portion, and the second spur gear portion is meshed with the transmission tooth 501 provided on the linkage rod 510. When the first rack 210 is meshed with the first gear 520, the first rack 210 drives the linkage rod 510 to rotate through the first gear 520, the second gear 530, the third gear 540 and the transmission tooth 501 in sequence. This embodiment adopts a gear transmission mode, which has a compact structure, reliable transmission, and has a higher transmission efficiency and transmission ratio, thereby improving the movement accuracy of the lifting support 300. In addition, compared with the embodiment in which the first rack 210 is directly meshed with the transmission tooth 501, the first gear 520, the second gear 530, and the third gear 540 can adapt to the distance between the first rack 210 and the transmission tooth 501, thereby facilitating the structural design of the electronic device.

[0072] It should be noted that, when the movable support 200 moves between the first position and the second position, the total tooth length of the first rack 210 passing through the first gear 520 is equal to the horizontal distance between the movable support 200 and the lifting support 300 .

[0073] Optionally, the first surface of the first body 100 is provided with a first center column 140, a second center column 150 and a first center hole 160, wherein the axis of the first center column 140 can be perpendicular to the axis of the second center column 150, the first gear 520 is sleeved on the first center column 140, the first gear 520 rotates around the first center column 140, the third gear 540 is sleeved on the second center column 150, the third gear 540 rotates around the second center column 150, and the first center hole 160 is rotated in coordination with the center column of the second gear 530.

[0074] The number of linkage rods 510 may be one. In another optional embodiment, the number of linkage rods 510 is at least two, and each linkage rod 510 is arranged at intervals along the moving direction of the moving support member 200. The transmission mechanism 500 also includes a second rack 550, and each linkage rod 510 is connected by transmission through the second rack 550. In this embodiment, each linkage rod 510 is connected by transmission through the second rack. When one linkage rod 510 is driven to rotate, the remaining linkage rods 510 can rotate accordingly. Therefore, this embodiment can improve the supporting effect of the linkage rod 510 on the lifting support member 300, and simplify the driving structure of each linkage rod 510. When the number of linkage rods 510 is at least two, including a first linkage rod and a second linkage rod, in the moving direction of the moving support member 200, the first linkage rod is supported at one end of the lifting support member 300, and the second linkage rod is supported at the other end of the lifting support member 300, thereby increasing the supporting area of ​​the linkage rod 510 and further improving the stability of the lifting support member 300.

[0075] In another optional embodiment, the electronic device also includes a first mounting member 610 and a second mounting member 620, the first mounting member 610 is provided with a first mounting groove 611, the second mounting member 620 is provided with a second mounting groove 621, the first mounting member 610 is connected to the second mounting member 620, so that the first mounting groove 611 and the second mounting groove 621 together form a mounting hole, the linkage rod 510 is provided with a positioning portion 512, the positioning portion 512 cooperates with the mounting hole, so as to position the linkage rod 510, so that the linkage rod 510 can rotate around its own axis in the mounting hole, and the linkage rod 510 is rotatably arranged on the first main body 100 through the first mounting member 610 and the second mounting member 620, so that the linkage rod 510 can rotate flexibly to avoid interference with the first main body 100.

[0076] Optionally, the first surface of the first body 100 is further provided with a first fixing groove 170, and at least a portion of the second mounting member 620 is installed in the first fixing groove 170, so as to position the second mounting member 620. Further optionally, a positioning hole 171 is provided at the bottom of the first fixing groove 170, and a positioning column 622 is provided on a side of the second mounting member 620 facing the bottom of the groove, and the positioning column 622 is positioned and matched with the positioning hole 171, so as to position the second mounting member 620.

[0077] Optionally, the first mounting member 610 is connected to the second mounting member 620 via a plurality of fasteners. Further optionally, the fasteners may be screws, etc., which are not specifically limited here.

[0078] Optionally, the number of the first mounting members 610 and the second mounting members 620 can be at least two, and each first mounting member 610 and each second mounting member 620 are arranged at intervals along the extension direction of the linkage rod 510, and each first mounting member 610 and each second mounting member 620 are arranged on both sides of the transmission mechanism, so as to position the two ends of the linkage rod 510 respectively to avoid displacement during the rotation of the linkage rod 510.

[0079] In another optional embodiment, the electronic device also includes a first elastic member 710, which is connected between the first body 100 and the lifting support member 300. When the movable support member 200 moves from the first position to the second position, that is, when the lifting support member 300 is lowered from the first height to the second height, the linkage rod 510 rotates until the end of the eccentric transmission part 511 away from the rotation axis of the linkage rod 510 is at the same height as the linkage rod 510, the first elastic member 710 restores its deformation and pulls the lifting support member 300 to the second position, so that the movable support member 200 covers the lifting support member 300.

[0080] Optionally, the electronic device further includes a first fixing member 730 and a second fixing member 740, the first surface of the first body 100 is further provided with a second fixing groove 180, the second fixing member 740 is fixedly arranged in the second fixing groove 180, the lifting support member 300 is provided with a third fixing groove 330 on a side facing away from the flexible display screen 400, the first fixing member 730 is fixedly arranged in the third fixing groove 330, and the first elastic member 710 is connected between the first fixing member 730 and the second fixing member 740, so that the first elastic member 710 is respectively connected to the first body 100 and the lifting support member 300.

Optionally, the fourth gear 560 and the lifting support member 300 can cooperate through friction. During the use of the electronic device, the lifting support member 300 is lifted and lowered frequently, so the fourth gear 560 and the lifting support member 300 are easily worn, which will cause the cooperation between the two to fail and require frequent maintenance. Therefore, in other embodiments, one of the fourth gear 560 and the lifting support member 300 is provided with a spiral groove 561, and the other is provided with a matching protrusion 310, and the matching protrusion 310 matches with the spiral groove 561. When the movable support member 200 is connected to the fourth gear 560, the movable support member 200 drives the fourth gear 560 to rotate through the transmission tooth 501. The fourth gear 560 rotates relative to the matching protrusion 310 while driving the matching protrusion 310 to move along the thickness direction of the electronic device. The matching protrusion 310 drives the lifting support member 300 to move. The fourth gear 560 drives the lifting support member 300 to move through the matching protrusion 310 and the spiral groove 561, so that the connection between the fourth gear 560 and the lifting support member 300 is more reliable and has a longer service life.

[0083] Optionally, the mobile support member 200 may be provided with a first rack 210. When the first rack 210 is meshed with the fourth gear 560, the mobile support member 200 may drive the fourth gear 560 to rotate through the first rack 210, thereby moving the lifting support plate 300. In another optional embodiment, the transmission mechanism 500 further includes a linkage plate 570, which is movably disposed on the first body 100, and the linkage plate 570 is provided with a third rack 571, which extends along the moving direction of the mobile support member 200, and the third rack 571 is meshed with the transmission gear 501. When the mobile support member 200 is connected to the linkage plate 570, the mobile support member 200 drives the linkage plate 570 to move, and the linkage plate 570 drives the fourth gear 560 to rotate through the third rack 571 and the transmission gear 501, and the fourth gear 560 drives the matching protrusion 310 to move, so that the linkage plate 570 drives the lifting support member 300 to move through the fourth gear 560. It can be seen that the transmission mechanism 500 in this embodiment has the characteristics of large power transmission and high transmission efficiency through the gear rack transmission mode, thereby improving the smoothness of movement of the lifting support member 300. In addition, the linkage plate 570 can be used as a transition component between the mobile support member 200 and the fourth gear 560, which is more convenient for setting the third rack 571 and other transmission structures.

[0084] It should be noted that when the movable support 200 moves between the first position and the second position, the total tooth length of the third rack 571 through the fourth gear 560 is equal to the horizontal distance between the movable support 200 and the lifting support 300, and is equal to the thickness of the movable support 200.

[0085] Optionally, the linkage plate 570 is provided with a connecting hole 573, which extends along the thickness direction of the electronic device. The hole wall of the connecting hole 573 is provided with a third rack 571, and at least a portion of the fourth gear 560 is located in the connecting hole 573, so as to make the transmission mechanism 500 more compact, thereby reducing the thickness of the electronic device.

[0086] When the mobile support 200 moves from the first position to the second position, a driving force can be provided by an additional driving device to drive the linkage plate 570 to move, but the driving device is relatively power-consuming, which will result in a reduction in the battery life of the electronic device. Based on this, in another optional embodiment, the electronic device also includes a second elastic member 720, and the second elastic member 720 is connected between the first body 100 and the linkage plate 570. In the process of the mobile support 200 moving from the second position to the first position, the second elastic member 720 is deformed along the moving direction of the mobile support 200; in the process of the mobile support 200 moving from the first position to the second position, the second elastic member 720 restores the deformation and provides power for the linkage plate 570, thereby saving electric energy and extending the battery life of the electronic device.

[0087] The movable support 200 and the linkage plate 570 may be connected by a flexible connection. When the movable support 200 moves from the second position to the first position, once the flexible connection is tightened, the movable support 200 can pull the linkage plate 570 to move through the flexible connection. However, when the movable support 200 is in the second position, the flexible connection is in a loose state, which is easy to affect other structures. In view of this, in a further optional embodiment, the movable support 200 is provided with a first pulling portion 220, and the linkage plate 570 is provided with a second pulling portion 572. When the electronic device is in a folded state, the first pulling portion 220 and the second pulling portion 572 are arranged at intervals along the moving direction of the movable support 200. When the first pulling portion 220 is connected to the second pulling portion 572, the movable support 200 drives the linkage plate 570 to move through the first pulling portion 220 and the second pulling portion 572, and the moving directions of the movable support 200 and the linkage plate 570 are the same. In this solution, the first pulling portion 220 is fixed to the movable support member 200, and the second pulling portion 572 is fixed to the linkage plate 570. When the first pulling portion 220 is connected to the second pulling portion 572, the contact area between the first pulling portion 220 and the second pulling portion 572 is larger, which is beneficial to dispersing the force between the two; and when the movable support member 200 is in the second position, the impact on other structures can be reduced.

[0088] Optionally, the first surface of the first main body 100 is provided with a first hanging portion 199, the linkage plate 570 is provided with a second hanging portion 574, one end of the second elastic member 720 is hung on the first hanging portion 199, and the second end of the second elastic member 720 is hung on the second hanging portion 574, so as to facilitate the setting of the second elastic member 720.

[0089] Further optionally, the second elastic member 720 includes a deformation portion 721, a third hanging portion 722 and a fourth hanging portion 723, the deformation portion 721 is connected between the third hanging portion 722 and the fourth hanging portion 723, the third hanging portion 722 cooperates with the first hanging portion 199, and the fourth hanging portion 723 cooperates with the second hanging portion 574, thereby improving the stability of the second elastic member 720.
