Detailed ways

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.

The terms "first", "second" and the like in the specification and claims of this application are used to distinguish similar objects. The terms "and/or" and "and/or" in the specification and claims generally represent at least one of the connected objects, and the character "/" generally indicates that the objects associated with each other are in an "or" relationship.

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.

1 to 36 b , an embodiment of the present application discloses an electronic device, including a first body 100 , a second body 800 , a movable support 200 , a lifting support 300 , a transmission mechanism 500 and a flexible display screen 400 .

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.

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.

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 .

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.

In the embodiment of the present application, the lifting support member 300 is movably disposed on the first body 100, and the mobile support member 200 is disposed 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 can retract and cover 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. The invention can solve the problem of abnormal noise in electronic equipment in the related art.

As shown in FIGS. 1 to 21 b , in an optional embodiment, the transmission mechanism 500 includes a linkage rod 510, which is rotatably disposed 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 is rotated. The lifting support member 300 is driven to move by the eccentric transmission part 511. 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 movable 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, the transmission chain is relatively short, and the transmission efficiency is relatively 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.

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.

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.

During the movement of the first rack 210, the guide groove 120 provides guidance for the first rack 210.

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. The sliding buckle 212 slidably cooperates with the sliding groove 130 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.

In a further optional embodiment, the transmission mechanism 500 further includes a first gear 520, a second gear 530 and a third gear 540, wherein the first gear 520 is rotatably disposed on the first body 100, and the second gear 530 meshes with the first gear 520. Alternatively, the first gear 520 may be a cylindrical gear, the cylindrical gear having a first gear portion and a second gear portion arranged at intervals, the first gear portion meshing with the first rack 210, the second gear portion meshing with the second gear 530, so as to avoid the first rack 210 and the second gear 530 from influencing each other, the third gear 540 meshing with the second gear 530, and the third gear 540 meshing with the transmission tooth 501, the axis of the second gear 530 intersecting with the axis of the third gear 540.

This embodiment adopts a gear transmission method, 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 gear 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 gear 501, thereby facilitating the structural design of the electronic device.

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 .

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 with the center column of the second gear 530.

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.

Optionally, the first surface of the first body 100 is further provided with a first fixing groove 170, and at least part of the second mounting member 620 It is installed in the first fixing groove 170 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 one 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 to position the second mounting member 620.

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.

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.

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.

As shown in Figures 25 to 36b, in another optional embodiment, the transmission mechanism 500 includes a fourth gear 560, and the fourth gear 560 is provided with a transmission tooth 501. 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.

In another optional embodiment, the transmission mechanism 500 further includes a linkage plate 570, which is movable. The linkage plate 570 is provided on the first main body 100, and is provided with a third rack 571, which extends along the moving direction of the mobile support 200, and the third rack 571 is meshed with the transmission tooth 501. When the mobile support 200 is connected to the linkage plate 570, the mobile support 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 tooth 501, and the fourth gear 560 drives the matching convex part 310 to move, so that the linkage plate 570 drives the lifting support 300 to move through the fourth gear 560.
