[0003] At present, electronic devices drive the flexible screen to expand and contract through the relative movement between two separately arranged shells, so that the screen size is reduced in the contracted state and increased in the expanded state. However, when the flexible screen is in the expanded state, due to the interval between the two shells, there is a gap between the two shells, thereby reducing the sealing performance of the electronic device. Summary of the invention

[0027] See also Figures 1 to 3 , an embodiment of the present application provides an electronic device, which may include a mobile phone, a tablet computer or a smart wearable device. As described in 1 to 3, the above electronic device includes:

[0028] Equipment body 10;

[0029] The first shell 20 and the second shell 30 are respectively movably connected to the device body 10, and the first shell 20 and the second shell 30 can move relative to each other and be in a closed state or a separated state;

[0030] The transmission assembly 40 is disposed in the device body 10. The transmission assembly 40 includes a pulley 41 and a transmission belt 42. The pulley 41 is movably disposed and can rotate. The transmission belt 42 is connected to the pulley 41, and the pulley 41 can drive the transmission belt 42 to move.

[0031] The filling assembly 50 is connected to the transmission belt 42, and the filling assembly 50 can shrink or stretch under the drive of the transmission belt 42, wherein:

[0032] When the first shell 20 and the second shell 30 are in a closed state, the first shell 20 and the second shell 30 form a receiving space, and the filling component 50 is retracted into the receiving space. Figure 2 As shown;

[0033] When the first shell 20 and the second shell 30 are in a separated state, a gap is formed between the first shell 20 and the second shell 30, and the filling component 50 is extended to fill the gap. Figure 3 shown.

[0034] Based on this, the electronic device includes a device body 10, a first shell 20, a second shell 30, a transmission assembly 40 and a filling assembly 50. Through the cooperation between the transmission assembly 40 and the filling assembly 50, when the first shell 20 and the second shell 30 are in a closed state, the filling assembly 50 shrinks into the receiving space formed by the first shell 20 and the second shell 30; and when the first shell 20 and the second shell 30 are in a separated state, the filling assembly 50 stretches and fills the gap formed between the first shell 20 and the second shell 30. In this way, when a gap is formed between the two shells, the electronic device can realize that the filling assembly 50 fills the gap, thereby improving the sealing performance of the electronic device (such as dustproof and waterproof, etc.); and when the two shells are in a closed state, that is, when the gap disappears, the filling assembly 50 is driven by the transmission assembly 40 to be received in the receiving space formed by the two shells, thereby ensuring the appearance of the electronic device.

[0035] In the embodiment of the present application, the electronic device includes a device body 10 .

[0036] The device body 10 may include components for realizing user functions of the electronic device, and when the first shell 20 and the second shell 30 are in a closed state to form a receiving space, the components of the device body 10 are all received in the receiving space.

[0037] For example, the above-mentioned device body 10 may include a frame and internal components housed in the frame. The frame is movably connected to the first shell 20 and the second shell 30, and when the first shell 20 and the second shell 30 are in a closed state, the frame is housed in a housing space formed by the first shell 20 and the second shell 30. The above-mentioned internal components may include a circuit board and components carried on the circuit board, and so on.

[0038] In the embodiment of the present application, the above-mentioned electronic device also includes a first shell 20 and a second shell 30, and the first shell 20 and the second shell 30 are respectively movably connected to the above-mentioned device body 10, and relative movement can occur between the first shell 20 and the second shell 30, so that the first shell 20 and the second shell 30 are in a closed state or in a separated state.

[0039] When the first shell 20 and the second shell 30 are in a closed state, the first shell 20 and the second shell 30 can form a receiving space; and when the first shell 20 and the second shell 30 are in a separated state, a gap (also called a "gap") can be formed between the first shell 20 and the second shell 30.

[0040] The above-mentioned first shell 20 and the second shell 30 are in a closed state, and the gap between the first shell 20 and the second shell 30 may be less than or equal to a first preset threshold; the above-mentioned first shell 20 and the second shell 30 are in a separated state, and the gap between the first shell 20 and the second shell 30 may be greater than or equal to a second preset threshold, and the second preset threshold is greater than or equal to the first preset threshold.

[0041] In the embodiment of the present application, the electronic device further includes a transmission assembly 40 , and the transmission assembly 40 is disposed in the device body 10 .

[0042] The transmission assembly 40 includes a pulley 41 and a transmission belt 42 . The pulley 41 is movably arranged and can rotate. The transmission belt 42 is connected to the pulley 41 , and the pulley 41 can drive the transmission belt 42 to move.

[0043] The pulley 41 may be any rotatable wheel-shaped structure, and its location, shape, size, etc. in the electronic device may be set according to actual needs and are not limited here.

[0044] For example, an annular groove may be provided on the circumferential side of the pulley 41 away from the axis thereof, the annular groove is arranged around the wheel body of the pulley 41, and at least part of the transmission belt 42 is movably connected in the annular groove.

[0045] The transmission belt 42 may be any belt-like structure connected to the pulley 41 and can be driven to move by the pulley 41 when the pulley 41 rotates. For example, when the pulley 41 is provided with an annular groove, the transmission belt 42 may be an annular rubber belt, and at least part of the annular rubber belt is movably engaged in the groove. When the pulley 41 rotates, the transmission belt is driven to rotate by the friction between the belt and the groove.

[0046] It should be noted that the above-mentioned pulley 41 can also be connected to other driving structures, and the driving structure can provide driving force for the pulley 41 to rotate the pulley 41.

[0047] For example, the electronic device may further include a driving assembly 60 , wherein the driving assembly 60 includes a driving motor and a gear. The driving motor is connected to the pulley 41 through the gear, and drives the pulley 41 to rotate through the gear.

[0048] In the embodiment of the present application, the electronic device further comprises a filling assembly 50 , and the filling assembly 50 is connected to the transmission belt 40 , and the filling assembly 50 can shrink or expand when driven by the transmission belt 42 .

[0049] When the first shell 20 and the second shell 30 are in a closed state, the filling assembly 50 is retracted into the accommodating space; and when the first shell 20 and the second shell 30 are in a separated state, the filling assembly 50 is extended and fills the gap between the first shell 20 and the second shell 30.

[0050] The above-mentioned implementation of the filling component 50 extending and filling the above-mentioned gap can be achieved after the relative movement between the first shell 20 and the second shell 30 stops and the gap is greater than or equal to the second preset threshold, and the transmission belt 42 drives the filling component 50 to extend and fill the above-mentioned gap; or, it can also be achieved during the process of the first shell 20 and the second shell 30 moving away from each other.

[0051] The filling component 50 shrinks to the accommodation space when the transmission component 40 drives the filling component 50 to shrink before the gap between the first shell 20 and the second shell 30 is about to shrink. Then the gap between the first shell 20 and the second shell 30 shrinks to be less than or equal to a first preset threshold value, and the filling component 50 is accommodated in the accommodation space. Alternatively, it may be achieved when the first shell 20 and the second shell 30 are moving closer to each other.

[0052] The filling component 50 may be any component that can fill the gap between the first shell 20 and the second shell 30 when the first shell 20 and the second shell 30 are in a separated state. For example, the filling component 50 may be a rubber block or the like.

[0053] The transmission belt 42 drives the filling assembly 50 to move. The user may input an operation to drive the transmission belt 42 to drive the pulley 41 to rotate, and the pulley 41 drives the filling assembly 50 to move.

[0054] The transmission belt 42 can drive the filling assembly 50 to retract or expand. The transmission belt 42 can drive the filling assembly 50 to retract and expand at different times; or the transmission belt 42 can only drive the filling assembly 50 to retract or expand.

[0055] Specifically, when the pulley 41 rotates in a first direction, the pulley 41 drives the filling assembly 50 to contract through the transmission belt 42; or, when the pulley 41 rotates in a second direction, the pulley 41 drives the filling assembly 50 to expand through the transmission belt 42, and the second direction is opposite to the first direction.

[0056] For example, when the driving assembly 60 drives the pulley 41 to rotate clockwise, the transmission belt 42 can drive the filling assembly 50 to move toward the equipment body 10 to shrink the filling assembly 50; and when the driving assembly 60 drives the pulley 41 to rotate counterclockwise, the transmission belt 42 can drive the filling assembly 50 to move away from the equipment body 10 to expand the filling assembly 50.

[0057] In some embodiments, the transmission assembly 40 further includes:

[0058] The first elastic member 43 is connected to the filling assembly 50 and the device body 10.

[0059] When the first shell 20 and the second shell 30 are in a closed state, the pulley 41 rotates in the first direction, the first elastic member 43 contracts, and the pulley 41 drives the filling assembly 50 to contract into the receiving space through the transmission belt 42;

[0060] When the first shell 20 and the second shell 30 are in a separated state, the first elastic member 43 provides elastic force to the filling assembly 50 and drives the filling assembly 50 to stretch, and the filling assembly 50 drives the pulley 41 to rotate along the second direction through the transmission belt 42, and the second direction is opposite to the first direction.

[0061] Based on this, the above-mentioned transmission assembly 40 also includes a first elastic member 43, and when the first shell 20 and the second shell 30 are in a closed state, the first elastic member 43 contracts, and the pulley 41 and the transmission belt 42 cooperate to drive the filling assembly 50 to contract; and when the first shell 20 and the second shell 30 are in a separated state, the first elastic member 43 provides elastic force to drive the filling assembly 50 to extend, so that the filling assembly 50 fills the gap between the first shell 20 and the second shell 30, thereby making the structure of the transmission assembly 40 simpler and saving the energy consumed by the electronic device to drive the filling assembly 50.

[0062] In this embodiment, the first elastic member 43 may be any elastic member, specifically, a spring or a spring sheet.

[0063] In order to achieve that the first elastic member 43 can drive the filling component 50 to extend when providing elastic force to the filling component 50, the above-mentioned pulley 41 can be arranged to rotate in the first direction and the second direction respectively. When the first shell 20 and the second shell 30 are in a closed state, the driving component 60 drives the pulley 41 to move in the first direction. At this time, the pulley 41 can drive the filling component 50 to shrink to the accommodating space through the transmission belt 42, and the first elastic member 43 shrinks under the extrusion of the filling component 50; when the first shell 20 and the second shell 30 are in a separated state, the driving component 60 controls the rotating shaft connected to the pulley 41 to idle. At this time, the first elastic member 43 drives the filling component 50 to extend, and the filling component 50 drives the pulley 41 to rotate in the second direction through the transmission belt 42.

[0064] In some embodiments, the transmission assembly 40 further includes:

[0065] A locking member 44, the locking member 44 is connected to the pulley 41, and the locking member 44 and the pulley 41 can be in a locked state or an unlocked state;

[0066] When the locking member 44 and the pulley 41 are in a locked state, the pulley 41 rotates in a first direction and drives the filling assembly 50 to contract;

[0067] When the locking member 44 and the pulley 41 are in the unlocked state, the pulley 41 is driven by the elastic force of the first elastic member 43 to rotate in the second direction, and the filling assembly 50 is extended.

[0068] Based on this, a locking member 44 is also provided in the transmission assembly 40. The locking member 44 and the pulley 41 are respectively in a locked state and an unlocked state, so that the pulley 41 can rotate in a first direction and a second direction respectively, thereby realizing the contraction and extension of the filling assembly 50, thereby making the structure of the electronic device simpler.

[0069] It should be noted that, when the above-mentioned pulley 41 is driven by the above-mentioned driving component 60, if the above-mentioned locking member 44 and the pulley 41 are in a locked state, then the driving component 60 drives the pulley 41 to rotate along the first direction; and if the above-mentioned locking member 44 and the pulley 41 are in an unlocked state, the driving component 60 can be stopped from applying driving force to the pulley 41, or the connection between the driving component 60 and the pulley 41 can be invalidated.

[0070] The locking member 44 may be any component that can be in a locked state and an unlocked state with the pulley 41, so that the pulley 41 can rotate in the second direction under the action of the first elastic member 43 in the unlocked state without being driven by other components.

[0071] For example, a lifting device may be provided in the transmission component 40, and when the lifting device does not lift the pulley 41, the pulley 41 is connected to the driving component 60, and the driving component 60 can drive the pulley 41 to rotate in a first direction; and when the lifting device lifts the pulley 41, the pulley 41 and the driving component 60 are separated, and the pulley 41 is only subjected to the force from the first elastic member 43 and can rotate in the second direction.

[0072] In some embodiments, the pulley 41 includes an axle 411 and a wheel body 412, wherein the axle 411 passes through the wheel body 412 and is movably connected to the wheel body 412;

[0073] The locking member 44 comprises:

[0074] A stopper 441, which is disposed on one side of the wheel body 412;

[0075] The connecting rod 442 is connected to the wheel axle 411 and rotates with the wheel axle 411, and the connecting rod 442 is located on the side of the wheel body 412 where the stopper 441 is provided.

[0076] When the locking member 44 and the pulley 41 are in a locked state, the connecting rod 442 abuts against the stopper 441, and the wheel body 412 can rotate in the first direction;

[0077] When the locking member 44 and the pulley 41 are in an unlocked state, the connecting rod 442 and the stopper 441 are offset, and the wheel body 412 can rotate in the second direction.

[0078] Based on this, by setting the stopper 441 and the connecting rod 442, when the connecting rod 442 abuts against the stopper 441, the wheel body 412 can rotate in the first direction; and when the connecting rod 442 and the stopper 441 are misaligned, the wheel body 412 can rotate in the second direction, thereby making the structure simple and highly reliable.

[0079] In this embodiment, when the connecting rod 442 abuts against the stop block 441, the wheel body 412 can rotate along the first direction. When the wheel axle 411 rotates along the first direction, the mutual abutment force between the connecting rod 442 and the stop block 441 drives the wheel body 412 to rotate along the first direction.

[0080] When the connecting rod 442 and the stopper 41 are offset, the wheel body 412 can rotate in the second direction. This may be because the connecting rod 442 and the stopper 41 are offset, resulting in no contact force between the connecting rod 442 and the stopper 41, so that the wheel shaft 411 cannot apply a driving force to the wheel body 412 through the connecting rod 442 and the stopper 441. At this time, if the first elastic member 43 is stretched, the first elastic member 43 can drive the wheel body 412 to rotate in the second direction through the transmission belt 42.

[0081] The above-mentioned misalignment between the connecting rod 442 and the stop block 441 can be achieved by further providing a push-pull mechanism in the transmission assembly 40, which can be connected to the wheel axle 411, and the push-pull mechanism can push the wheel axle 411 to move along the third direction, so that the connecting rod 442 and the stop block 441 are in the same plane, so that they can abut against the stop block 441 when the connecting rod 442 rotates; and the push-pull mechanism can pull the wheel axle 411 to move in the fourth direction, so that the connecting rod 442 and the stop block 441 are not in the same plane, that is, the connecting rod 442 and the stop block 441 are misaligned, so that the connecting rod 442 cannot apply a driving force to the wheel body 412.

[0082] In some embodiments, the locking member 44 further comprises:

[0083] The boss 443 is spaced apart from the wheel body 412 and connected to the device body 10, and the boss 443 is provided with a guide slope 4430.

[0084] When the connecting rod 442 rotates along the first direction and passes through the guiding inclined surface 4430 , the connecting rod 442 is offset from the stopper 441 .

[0085] Based on this, the guide slope 4430 of the boss 443 can guide the connecting rod 442 and the stopper 441 to be offset when the connecting rod 442 rotates along the first direction, making the method of offsetting the connecting rod 442 and the stopper 441 simpler and more reliable.

[0086] For example, when the gear 62 of the driving assembly 60 is engaged with the axle 411, if the driving motor 61 drives the axle 411 to rotate through the gear 62, the axle 411 drives the connecting rod 442 to rotate clockwise, and when the connecting rod 442 rotates to abut against the stop block 441, the connecting rod 442 drives the wheel body 412 to rotate clockwise through the stop block 441, thereby driving the filling assembly 50 to contract. At this time, the connecting rod 442 and the boss 443 can have a certain distance; and the driving motor 61 can continue to drive the connecting rod 442 to rotate clockwise until the connecting rod 442 passes through the boss 443, and the connecting rod 442 and the stop block 441 are misaligned when the boss 443 passes through its guide slope 4430. At this time, the wheel body 412 rotates counterclockwise instantaneously under the action of the first elastic member 43, causing the filling assembly 50 to contract and expand.

[0087] In some embodiments, the pulley 41 further comprises:

[0088] The second elastic member 413 is disposed on a side of the wheel body 412 away from the connecting rod 442 , and is used to provide an elastic force to the wheel body 412 toward the connecting rod 442 .

[0089] Based on this, by providing the second elastic member 413 , after the connecting rod 442 and the stopper 441 are misaligned, the contact between the connecting rod 442 and the stopper 441 can be restored, thereby realizing the cyclic operation of the transmission assembly 40 .

[0090] For example, when the above-mentioned boss 443 causes the connecting rod 442 and the stop block 441 to be misaligned through its guiding bevel 4430, the connecting rod 442 can continue to rotate clockwise under the drive of the driving motor 61. After the connecting rod 442 disengages from the guiding bevel 4430, the second elastic member 413 can provide an elastic force to the wheel body 412 in the direction of the connecting rod 442, so that the connecting rod 442 and the stop block 441 are restored to be in the same plane.

[0091] It should be noted that, when the connecting rod 442 passes through the guiding inclined surface 4430 , the second elastic member 413 may contract, thereby achieving misalignment between the connecting rod 442 and the stopper 441 .

[0092] The second elastic member 413 may be any elastic component, specifically, the second elastic member 413 may be a spring or a spring. For example, the second elastic member 413 may be a spring, and the shaft passes through the spring, and one end of the spring is connected to the shaft, and the other end is movably abutted against the wheel body 412.

[0093] In some embodiments, the transmission assembly 40 further includes:

[0094] A connecting rod 45, the connecting rod 45 is connected to the filling assembly 50;

[0095] A slider 46, the slider 46 is movably disposed on the connecting rod 45 and connected to the transmission belt 42, and;

[0096] The sliding guide 47 is connected with the slider 46.

[0097] When the filling assembly 50 is contracted or expanded, the slider 46 slides on the connecting rod 45 along the sliding guide 47 .

[0098] Based on this, the filling component 50 is connected by the connecting rod 45, and the slider 46 on the connecting rod 45 is connected with the sliding guide 47, so that when the transmission component 40 drives the filling component 50 to move, the sliding guide 47 can guide the movement direction of the filling component 50, thereby making the movement of the filling component 50 more stable.

[0099] In the embodiment of the present application, the connecting rod 45 may be any component that serves to connect the filling assembly 50 and the transmission belt 42 . For example, the connecting rod 45 may be a metal component.

[0100] The sliding guide 47 may be a component that guides the sliding direction of the slider 46. For example, the sliding guide 47 may be a slide groove, and the slider 46 is movably embedded in the slide groove; or, the sliding guide 47 may be a slide rail, and the slider 46 engages with the slide rail, and so on.

[0101] In the case where the transmission assembly 40 further includes a first elastic member 43 , the first elastic member 43 may be disposed outside the sliding guide member 47 .

[0102] In some embodiments, the first elastic member 43 of the transmission assembly 40 is disposed on the sliding guide member 47 .

[0103] Based on this, by arranging the first elastic member 43 on the sliding guide member 47, not only the movement of the filling assembly 50 can be made more stable, but also the installation space can be saved.

[0104] In some embodiments, the electronic device further comprises:

[0105] The scroll screen 70 is connected to the first shell 20 and the second shell 30.

[0106] Wherein, when the first shell 20 and the second shell 30 are in a closed state, the scroll screen 70 is in a retracted state;

[0107] When the first shell 20 and the second shell 30 are in the separated state, the roll screen 70 is in the unfolded state.

[0108] Based on this, when the scroll screen 70 of the electronic device is in the unfolded state, the gap between the first shell 20 and the second shell 30 can be filled by the filling component 50 to improve the sealing of the scroll screen 70 electronic device.

[0109] In the present embodiment, the scroll screen 70 is switched between the expanded state and the retracted state by further providing a scroll screen 70 driving component in the electronic device, and the scroll screen 70 driving component is independently provided with the driving component 60 .

[0110] In some embodiments, the electronic device further comprises:

[0111] The driving assembly 60 is connected with the transmission assembly 40 and the scroll screen 70.

[0112] The driving assembly 60 can drive the scroll screen 70 to be in a retracted state or an extended state, and drive the pulley 41 to rotate.

[0113] Based on this, the driving component 60 can drive the scroll screen 70 and the transmission component 40 to move, thereby saving the installation space inside the electronic device and making the structure of the electronic device simpler.

[0114] For example, when the scroll screen 70 of the electronic device is in an expanded state and needs to be retracted, the driving component 60 can first drive the transmission component 40 to drive the filling component 50 to retract, and when the filling component 50 is retracted and the gap between the first shell 20 and the second shell 30 is reduced, the driving component 60 drives the scroll screen 70 to retract.

[0115] In some embodiments, see also Figure 8 , the filling assembly 50 includes at least one filling member 51;

[0116] The transmission assembly 40 includes at least one transmission belt 42 . The at least one transmission belt 42 is connected to at least one filling piece 51 in a one-to-one correspondence, and each transmission belt 42 is connected to its corresponding filling piece 51 and the pulley 41 .

[0117] Based on this, by setting at least one filling piece 51 in one-to-one correspondence with at least one transmission belt 42, and the transmission belt 42 can be connected to its corresponding filling piece 51 and the pulley 41, it is possible not only to fill the gap between the first shell 20 and the second shell 30 at multiple or at least one position, but also to drive multiple filling pieces 51 to move at the same time through one pulley 41.

[0118] The filling assembly 50 may include only one filling piece 51 , and the filling piece 51 may be disposed on any side surface of the device body 10 .

[0119] Alternatively, the at least one filler comprises a first filler and a second filler,

[0120] When the first shell 20 and the second shell 30 are in a separated state, the first filling piece is located on the first side of the device body 10 away from the display side, and the second filling piece is located on the second side of the device body. The first side and the second side are adjacent and arranged at an angle.

[0121] Based on this, the transmission assembly 40 can simultaneously drive the filling members 51 on different sides to move, thereby making the structure of the electronic device simpler and more reliable.

[0122] For example, Figure 8 As shown, the at least one filling piece 51 includes a filling plate A and a filling plate B, the filling plate A is located on the back cover side of the electronic device, the filling plate B is located on the frame side of the electronic device, and the filling plate A and the filling plate B are arranged at an angle of 90°. When the first shell 20 and the second shell 30 are in a closed state, the transmission assembly 40 can simultaneously drive the filling plate A to move along the X1 direction, and drive the filling plate B to move along the X2 direction, so as to realize the contraction of the filling plate A and the filling plate B.

[0123] It should be noted that, when the above-mentioned filling assembly 50 includes multiple filling pieces 51, the above-mentioned pulley includes multiple wheel bodies, and the multiple wheel bodies, multiple transmission belts and multiple filling pieces are arranged one by one; similarly, it can also include multiple groups of first elastic members 43, connecting rods 45, sliders 46 and sliding guide members 47, which are not elaborated here.

[0124] Other structures and operations of the electronic device according to the embodiments of the present application are known to those skilled in the art and will not be described in detail here.
