Description

Technical Field

[0001] The present invention relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0002] Currently, electronic products such as mobile phones and laptops have a variety of screen styles, with the majority featuring foldable structures, such as inward-folding, outward-folding, and multi-folding. Their ultimate goal is to transform a small screen into a larger one. In related technologies, foldable electronic products typically utilize hinge structures to achieve inward or outward folding. However, this doubles the thickness of the electronic product after folding. Generally, foldable products are 4mm to 6mm thicker than standard products. Furthermore, multiple folds inevitably create creases on the screen, severely impacting the user experience. Currently, there is no effective solution to address these creases. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0004] To this end, an embodiment of the present invention provides an electronic device capable of avoiding the generation of creases.

[0005] An electronic device according to an embodiment of the present invention includes a housing, a screen, a supporting device and a retractable device, wherein the screen is a flexible screen and includes a first part and a second part that are connected; the supporting device is slidably connected to the housing along a first direction, and the supporting device includes a first supporting plate, and the first part is arranged on the upper surface of the first supporting plate; the retractable device is arranged in the housing, and the retractable device is used to drive the supporting device to slide and drive the screen to switch between a retracted position and a flattened position, in which the second part is bent along the side of the first supporting plate in the first direction and hidden between the first supporting plate and the housing, and in the flattened position, the second part is completely flattened and flush with the first part.

[0006] The electronic device of the embodiment of the present invention is provided with a supporting device and a retractable device. The retractable device drives the screen to switch between a flat position and a retracted position, thereby realizing the switching of the screen between large and small sizes and avoiding the problem of creases on the screen caused by the folding hinge.

[0007] In some embodiments, the support device further includes a first side panel and a second side panel, wherein the first side panel is connected to one side of the first support panel in the second direction, and the second side panel is connected to the other side of the first support panel in the second direction, and the inner wall of the first side panel and the inner wall of the second side panel are both provided with a slide groove opened along the first direction, and the two ends of the shell in the second direction are respectively slidably engaged in the slide grooves of the first side panel and the second side panel. Thus, in these embodiments, the electronic device of the embodiment of the present invention forms a sliding pair between the support device and the shell by providing the first side panel and the second side panel, and providing the slide grooves on the first side panel and the second side panel. The screen is retracted by sliding between the support device and the shell, thereby reducing the resistance between the support device and the shell and reducing the difficulty of processing the support device and the shell.

[0008] In some embodiments, the sliding grooves on the inner walls of the first side panel and the second side panel are both arc-shaped grooves. Thus, in these embodiments, the electronic device of the present invention increases the contact area between the support device and the housing when sliding by setting the sliding grooves as arc-shaped grooves.

[0009] In some embodiments, the electronic device further comprises a flexible support plate, the flexible support plate being connected to the lower surface of the second portion to support the second portion. In the retracted position, the flexible support plate is hidden between the first support plate and the housing along with the second portion. In the flattened position, the upper surface of the flexible support plate is flush with the upper surface of the first support plate. Thus, in these embodiments, the electronic device of the present invention supports and guides the screen by providing the flexible support plate, preventing the screen's R angle from deviating from the designed value during movement in the retracted position, thereby preventing friction between the screen and the housing. This avoids damage to the screen and prevents the large force required to retract the screen.

[0010] In some embodiments, the upper surface of the flexible support plate is provided with protrusions extending along the first direction at both ends in the second direction, and the height of the protrusions is the same as the thickness of the screen. Thus, in these embodiments, the electronic device of the present invention avoids a step between the support device and the housing through the provision of the protrusions, thereby preventing the retractable device from being exposed.

[0011] In some embodiments, the retractable device includes a second support plate and a drive assembly. Two drive assemblies are provided, one at each end of the second support plate in the second direction. Both drive assemblies are connected to the support device and the flexible support plate to drive the support device and the flexible support plate to slide synchronously along the first direction. Thus, in these embodiments, the electronic device of the present invention, through the provision of the second support plate and the drive assembly, allows the support device to move synchronously with the screen along the first direction when the screen is retracted, thereby compensating for the reduced screen size.

[0012] In some embodiments, a guide rail extending along a first direction is provided on a side of the first support plate adjacent to the second support plate, and a guide groove corresponding to the guide rail is provided on a side of the second support plate adjacent to the first support plate, wherein the guide rail is slidably engaged within the guide groove. Thus, in these embodiments, the electronic device of the present invention forms a sliding pair between the first support plate and the second support plate through the provision of the guide rail and the guide groove, facilitating relative sliding between the first support plate and the second support plate.

[0013] In some embodiments, the second support plate is provided with a plurality of first grooves, wherein support members are provided in the first grooves, and the surface of the support members is smooth. Thus, in these embodiments, the electronic device according to the present invention can ensure normal sliding between the first support plate and the second support plate after the first support plate is deformed by providing the support members.

[0014] In some embodiments, the second support plate has a second groove on a side adjacent to the second portion in the first direction, and a rotatable roller is disposed within the second groove, with the roller's axial direction being arranged along the second direction. Thus, in these embodiments, the electronic device of the present invention, through the roller design, converts sliding friction between the screen and the housing into rolling friction, thereby reducing the load on the power pack.

[0015] In some embodiments, the drive assembly includes a synchronization group, a power group, and a fixing group. The synchronization group is connected to the first support plate and the flexible support plate; the power group is connected to the synchronization group to provide power to the synchronization group; and the fixing group is used to integrate and fix the synchronization group and the power group together. Therefore, in these embodiments, the electronic device of the present invention, through the configuration of the synchronization group, the power group, and the fixing group, enables the drive assembly to drive the screen to switch between a flattened position and a retracted position, thereby achieving switching between large and small screen sizes.

[0016] In some embodiments, the synchronization group includes a synchronization belt, a first synchronization gear, and a second synchronization gear. The synchronization belt is a closed ring with teeth provided on its inner circumference. The first synchronization gear and the second synchronization gear are both provided within the synchronization belt and are located at both ends of the synchronization belt in a first direction. The first synchronization gear and the second synchronization gear both mesh with the teeth on the synchronization belt. Therefore, in these embodiments, the electronic device of the present invention further implements the function of switching the screen between a flat position and a retracted position through the provision of the synchronization belt, the first synchronization gear, and the second synchronization gear.

[0017] In some embodiments, the electronic device further comprises a synchronization connecting plate, the ends of which are respectively connected to the synchronization belts of the two drive assemblies to enable the two synchronization belts to move synchronously, and the upper surface of the synchronization connecting plate is connected to the screen. Thus, in these embodiments, the electronic device of the present invention, through the provision of the synchronization connecting plate, can rigidly synchronize the two drive assemblies when deviation occurs in the movement of the two drive assemblies, thereby preventing the asynchronous movement of the two drive assemblies from pulling on the screen and causing damage to the screen.

[0018] In some embodiments, the synchronous belt is adhesively connected to the flexible support plate; or, the outer circumference of the synchronous belt is provided with a plurality of protrusions spaced along a first direction, the flexible support plate is provided with a plurality of through holes, the protrusions fit into the through holes, and the synchronous belt is thermally melted to the flexible support plate. Thus, in these embodiments, the electronic device of the present invention securely connects the synchronous belt and the flexible support plate, so that the flexible support plate moves synchronously with the synchronous belt.

[0019] In some embodiments, the power unit includes a motor and a reduction gear unit, and the motor is connected to the first synchronous gear through the reduction gear unit. Thus, in these embodiments, the electronic device of the present invention transmits the power of the motor to the synchronous belt through the arrangement of the motor and the reduction gear unit, thereby providing power to the synchronous belt.

[0020] In some embodiments, the fixed group includes a fixed frame, a motion guide rail, an upper movable member, and a lower movable member. The fixed frame has a belt groove opened along a first direction, a synchronous belt track is provided in the belt groove, and the synchronous belt can be slidably fitted on the synchronous belt track. Both ends of the fixed frame are provided with mounting holes for installing the first synchronous gear and the second synchronous gear; the motion guide rail is provided in the belt groove; the upper movable member and the lower movable member can both be slidably fitted on the motion guide rail, the upper movable member is connected to the upper belt layer of the synchronous belt, and the lower movable member is connected to the lower belt layer of the synchronous belt. Thus, in these embodiments, the electronic device of the embodiment of the present invention fixes the drive assembly on the housing through the arrangement of the fixed frame, the motion guide rail, the upper movable member, and the lower movable member, and supports the synchronous belt.

[0021] In some embodiments, the electronic device further comprises a connector that sequentially passes through the first support plate, the synchronous connection plate, and the timing belt, and is connected to the upper moving member. Thus, in these embodiments, the electronic device of the present invention secures the screen to the timing belt via the connector, preventing damage to the screen caused by significant friction between the screen and the housing due to bending forces.

[0022] In some embodiments, the fixing group further includes a tensioning screw, an elastic washer, and a tensioning spring. The fixing frame includes a first section and a second section spaced apart in a first direction. The first section is provided with a partition, and the tensioning screw passes through the partition and is threadedly connected to the second section. The elastic washer is provided between the screw head of the tensioning screw and the partition. The tensioning spring is sleeved on the outside of the tensioning screw, with one end of the tensioning spring abutting against the partition, and the other end of the tensioning spring abutting against the second section. Thus, in these embodiments, the electronic device of the present invention is provided with the tensioning screw, the elastic washer, and the tensioning spring. When the synchronous belt is deformed, the tensioning spring pushes the first section and the second section of the fixing frame to move in opposite directions along the first direction, thereby re-tensioning the deformed synchronous belt.

[0023] In some embodiments, the housing includes a bottom cover, a back cover, and side covers, the retractable device is disposed within the bottom cover; the back cover is connected to the lower surface of the bottom cover; and the side covers are connected to both ends of the bottom cover in the second direction. Thus, in these embodiments, the electronic device of the present invention, through the provision of the bottom cover, back cover, and side covers, encloses the components within the housing.

[0056] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0057] The electronic device according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0058] like Figure 1 and Figure 2 As shown, the electronic device according to the embodiment of the present invention includes a housing 10 , a screen 20 , a supporting device 30 and a retracting device 40 .

[0059] The screen 20 is a flexible screen, and includes a first portion 21 and a second portion 22 connected to each other; the supporting device 30 is arranged along a first direction ( Figure 1 The support device 30 is slidably connected to the housing 10 in the front and rear directions indicated by the middle arrow, and the first part 21 is arranged on the upper surface of the first support plate 31; the retracting device 40 is arranged in the housing 10, and the retracting device 40 is used to drive the support device 30 to slide and drive the screen 20 to switch between the retracted position and the flattened position. In the retracted position, the second part 22 is bent downward along the rear side of the first support plate 31 and is hidden between the first support plate 31 and the housing 10. In the flattened position, the second part 22 is completely flattened and flush with the first part 21.

[0060] It should be noted that when the retracting device 40 drives the first support plate 31 and the screen 20 to move toward the retracted position, the second portion 22 of the screen 20, under the action of the retracting device 40, bends downward along the rear side of the first support plate 31 and is hidden between the first support plate 31 and the housing 10. At the same time, the first support plate 31, driven by the screen 20, moves toward the retracted position, compensating for the reduced size of the screen 20 and achieving the reduction in size of the screen 20. When the retracting device 40 drives the first support plate 31 and the screen 20 to move toward the flattened position, the second portion 22 of the screen 20, hidden between the first support plate 31 and the housing 10, bends upward along the rear side of the first support plate 31, thereby moving the second portion 22 hidden between the first support plate 31 and the housing 10 to the exterior of the housing 10 and flush with the first portion 21. At the same time, the first support plate 31, driven by the screen 20, moves toward the flattened position, achieving the expansion of the screen 20.

[0061] The electronic device of the embodiment of the present invention is provided with a support device 30 and a retractable device 40. The retractable device 40 drives the screen 20 to switch between a flattened position and a retracted position, thereby realizing the switching of the screen between large and small sizes and avoiding the problem of creases on the screen caused by the folding hinge.

[0062] like Figures 3 to 5As shown, in some embodiments, the support device 30 further includes a first side plate 32 and a second side plate 33. The first side plate 32 is connected to the left side of the first support plate 31, and the second side plate 33 is connected to the right side of the first support plate 31. The inner wall of the first side plate 32 and the inner wall of the second side plate 33 are both provided with a slide groove 34 extending along a first direction. The left and right ends of the housing 10 are slidably engaged in the slide grooves 34 of the first side plate 32 and the second side plate 33, respectively. The electronic device of the embodiment of the present invention forms a sliding pair between the support device 30 and the housing 10 by providing the first side plate 32 and the second side plate 33 and providing the slide grooves 34 on the first side plate 32 and the second side plate 33. The support device 30 and the housing 10 are slidably moved by sliding between the support device 30 and the housing 10, thereby reducing the resistance between the support device 30 and the housing 10 and lowering the difficulty of manufacturing the support device 30 and the housing 10.

[0063] Furthermore, if Figure 5 As shown, the sliding grooves 34 on the inner walls of the first side panel 32 and the second side panel 33 are both arc-shaped grooves. The arc-shaped grooves increase the contact area between the supporting device 30 and the housing 10 and make the appearance of the electronic device more beautiful. The top surface of the arc-shaped groove is set to be square to limit the shaking of the housing 10.

[0064] like Figure 2 and Figure 6 As shown, the electronic device according to the embodiment of the present invention further includes a flexible support plate 50, which is connected to the lower surface of the second portion 22 to support the second portion 22. In the retracted position, the flexible support plate 50 is hidden along with the second portion 22 between the first support plate 31 and the housing 10. In the flattened position, the upper surface of the flexible support plate 50 is flush with the upper surface of the first support plate 31. The electronic device according to the embodiment of the present invention supports and guides the screen 20 by providing the flexible support plate 50. This prevents the screen 20 from rubbing against the housing 10 due to the R angle of the screen 20 deviating from the designed value during movement in the retracted position, thereby avoiding damage to the screen 20 and the large force required to retract the screen 20.

[0065] Furthermore, if Figure 7 As shown, the left and right ends of the upper surface of the flexible support plate 50 are provided with bosses 51 extending along the first direction. The height of the bosses 51 is the same as the thickness of the screen 20, avoiding the generation of a step between the support device 30 and the shell 10, thereby avoiding exposing the retractable device 40.

[0066] like Figure 2 and Figure 14As shown, in some embodiments, the retractable device 40 includes a second support plate 41 and a drive assembly 42. Two drive assemblies 42 are provided, one at each left and right end of the second support plate. Both drive assemblies 42 are connected to the support device 30 and the flexible support plate 50 to drive the support device 30 and the flexible support plate 50 to slide synchronously along the first direction. In the electronic device of the present invention, by configuring the second support plate 41 and the drive assembly 42, the support device 30 moves synchronously with the screen 20 along the first direction when the screen is retracted, compensating for the reduction in size of the housing 10 due to the shrinkage of the screen 20.

[0067] like Figure 8 、 Figure 11 and Figure 12 As shown, in some embodiments, a guide rail 311 extending along a first direction is provided on a side of the first support plate 31 adjacent to the second support plate 41, and a guide groove 411 corresponding to the guide rail 311 is provided on a side of the second support plate 41 adjacent to the first support plate 31. The guide rail 311 is slidably engaged in the guide groove 411. In the electronic device according to the embodiment of the present invention, the provision of the guide rail 311 and the guide groove 411 forms a sliding pair between the first support plate 31 and the second support plate 41, restricting the first support plate 31 and the second support plate 41 to slide only along the first direction, thereby preventing the first support plate 31 and the second support plate 41 from sliding in directions other than the first direction. At the same time, the guide rail 311 and the guide groove 411 reduce the frictional resistance between the first support plate 31 and the second support plate 41, thereby facilitating relative sliding between the first support plate 31 and the second support plate 41.

[0068] like Figures 8 to 12 As shown, in some embodiments, the second support plate 41 is provided with a plurality of first grooves 412, and support members 413 are provided in the first grooves 412. The surface of the support members 413 is smooth. In the electronic device of the embodiment of the present invention, the support members 413 are provided. After the first support plate 31 is deformed, the support members 413 keep the first support plate 31 and the second support plate 41 separated. The smooth support members 413 reduce the frictional resistance between the first support plate 31 and the second support plate 41, ensuring normal sliding between the first support plate 31 and the second support plate 41.

[0069] like Figure 14 As shown, in some embodiments, the second support plate 41 is provided with a second groove 414 at the rear side, and a rotatable roller 415 is provided in the second groove 414. The axial direction of the roller 415 is along the second direction ( Figure 14 The electronic device of the embodiment of the present invention converts the sliding friction between the screen 20 and the housing 10 into rolling friction through the design of the roller 415, thereby reducing the load on the power group.

[0070] Optionally, the roller 415 is divided into three sections, and two adjacent sections of the roller 415 are connected via bearings, thereby ensuring that the roller 415 will not be deformed during processing due to being too long.

[0071] like Figure 15 As shown, in some embodiments, the drive assembly 42 includes a synchronization group 421, a power group 422, and a fixing group 423. The synchronization group 421 is connected to the first support plate 31 and the flexible support plate 50; the power group 422 is connected to the synchronization group 421 to provide power to the synchronization group 421; and the fixing group 423 is used to integrate and fix the synchronization group 421 and the power group 422 together. The electronic device of the present invention, through the arrangement of the synchronization group 421, the power group 422, and the fixing group 423, enables the drive assembly 42 to drive the screen to switch between the flattened position and the retracted position, thereby achieving the switching of the screen 20 between large and small sizes.

[0072] like Figure 16 As shown, in some embodiments, the synchronization group 421 includes a synchronization belt 4211, a first synchronization gear 4212 and a second synchronization gear 4213. The synchronization belt 4211 is a closed ring, and teeth are provided on the inner circumference of the synchronization belt 4211; the first synchronization gear 4212 and the second synchronization gear 4213 are both provided in the synchronization belt 4211, and are respectively located at the front and rear ends of the synchronization belt 4211. The first synchronization gear 4212 and the second synchronization gear 4213 are both engaged with the teeth on the synchronization belt 4211. The first synchronization gear 4212 and the power group 422 are connected via an axis transmission, so that the power of the power group 422 is transmitted to the first synchronization gear 4212 through the shaft, and the first synchronization gear 4212 drives the synchronization belt 4211 to rotate. The electronic device of the embodiment of the present invention transmits the power of the power group 422 to the synchronous belt 4211 through the setting of the synchronous belt 4211, the first synchronous gear 4212 and the second synchronous gear 4213, thereby realizing the function of the synchronous belt 4211 driving the screen 20 to switch between the flattened position and the retracted position.

[0073] like Figure 2 and Figure 14 As shown, the electronic device according to the embodiment of the present invention further includes a synchronization connection plate 4214. The left and right ends of the synchronization connection plate 4214 are respectively connected to the synchronization belts 4211 of the two drive assemblies 42 to synchronize the movement of the two synchronization belts 4211. The upper surface of the synchronization connection plate 4214 is connected to the screen 20. Due to the provision of the synchronization connection plate 4214, the electronic device according to the embodiment of the present invention can rigidly synchronize the movement of the two synchronization belts 4211 when the two synchronization belts 4211 deviate from each other, thereby preventing the two synchronization belts 4211 from pulling on the screen 20 due to asynchronous movement, thereby causing damage to the screen 20.

[0074] Optionally, the synchronous belt 4211 is bonded to the flexible support plate 50. By bonding the synchronous belt 4211 and the flexible support plate 50, the flexible support plate 50 and the synchronous belt 4211 move synchronously, avoiding relative movement between the synchronous belt 4211 and the flexible support plate 50. This method is simple to operate and has low processing cost.

[0075] Optional, such as Figure 6 and Figure 23 As shown, the outer circumference of the synchronous belt 4211 is provided with a plurality of protrusions spaced along a first direction, and the flexible support plate 50 is provided with a plurality of through-holes, into which the protrusions fit, and the synchronous belt 4211 is heat-melted to the flexible support plate 50. The synchronous belt 4211 and the flexible support plate 50 are clamped and heat-melted together via the protrusions and through-holes, so that the flexible support plate 50 and the synchronous belt 4211 move synchronously, preventing relative movement between the synchronous belt 4211 and the flexible support plate 50. This method makes the connection between the synchronous belt 4211 and the flexible support plate 50 more reliable.

[0076] like Figure 16 As shown, in some embodiments, the power group 422 includes a motor 4221 and a reduction gear group 4222. The motor 4221 is in transmission connection with the first synchronous gear 4212 via the reduction gear group 4222. The reduction gear group 4222 can use a gear pair with a reduction ratio of 2.5:1. The reduction gear group 4222 can be in transmission connection with the first synchronous gear 4212 via a transmission shaft. The electronic device of the embodiment of the present invention transmits the power of the motor 4221 to the synchronous belt 4211 through the arrangement of the motor 4221 and the reduction gear group 4222, thereby providing power to the synchronous belt 4211.
