[0002] With the development and application of flexible screens, rollable screen phones have emerged in existing technologies. These phones typically use a support rod to support the flexible screen, which is connected to the support rod to form a whole. The size of the phone screen is changed by rolling the support rod and the flexible screen together. However, in existing technologies, the flexible screen is prone to detaching from the support rod during the rolling process, causing it to arch and potentially damage itself. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide a support device that enables a flexible screen to remain detached from the support device and arch during unfolding or rolling. The present invention also provides a housing equipped with the aforementioned support device, and an electronic device equipped with the aforementioned housing.

[0004] This invention provides a support device comprising a plurality of support rods connected in sequence. Each support rod has a first guide bend and a second guide bend on opposite sides. Adjacent support rods are rotatably connected by the cooperation of the first guide bend and the second guide bend. Each support rod also has a first abutment and a second abutment on opposite sides. When the plurality of support rods are in a flattened state, adjacent support rods abut against each other by the cooperation of the first abutment and the second abutment.

[0005] This invention also provides a housing, characterized in that the housing includes a support device, a first housing, and a second housing, the first housing and the second housing being slidably connected to each other, the support device being slidably mounted around the second housing, and one side of the support device being fixedly connected to the first housing; when the first housing and the second housing slide relative to each other, the support device rolls around the second housing.

[0006] This invention also provides an electronic device, which includes a housing and a flexible screen. The flexible screen includes a positioning area and a sliding area. The positioning area is fixed to a first housing within the housing, and the sliding area is attached to the front of the support device within the housing.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0051] It should be noted that, in this document, the reference to "embodiment" or "implementation" means that a specific feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0052] The terms "first" and "second" used in this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0053] Please refer to the following: Figures 1-9The electronic device 100 of one embodiment of the present invention can be applied to mobile phones, tablet computers, computers, laptops, monitors, vehicle cameras, cameras, smartwatches, smart bracelets, smart glasses, portable multimedia players, and mobile medical devices. This embodiment uses a mobile phone as an example for specific description. The electronic device 100 in this embodiment includes a housing 20 and a flexible screen 50. The housing 20 includes a support device 22, a first housing 24, and a second housing 26. The first housing 24 and the second housing 26 are slidably connected to each other, allowing them to retract or expand relative to each other. The support device 22 is slidably wound around the second housing 26, and one side of the support device 22 is fixedly connected to the first housing 24. The flexible screen 50 includes a positioning area 52 and a sliding area 54 located on one side of the positioning area 52. The positioning area 52 is fixed to the front of the first housing 24, and the sliding area 54 is attached to the surface of the support device 22 facing away from the second housing 26, i.e., the sliding area 54 is attached to the front of the support device 22 of the housing 20. A positioning strip 521 is provided on the side of the positioning area 52 away from the sliding area 54. When the first housing 24 and the second housing 26 slide relative to each other, the support device 22 slides around the second housing 26, and the sliding area 54 slides around the second housing 26 along with the support device 22. Specifically, when the second housing 26 extends relative to the first housing 24 in the first direction, that is, when the second housing 26 moves away from the first housing 24 relative to the first housing 24 in the X-axis direction, the second housing 26 drives the support device 22 to slide and unfold relative to the second housing 26, and the sliding area 54 unfolds synchronously with the support device 22, thereby increasing the display area of ​​the flexible screen 50; when the second housing 26 contracts relative to the first housing 24 in the opposite direction to the first direction, that is, when the second housing 26 moves closer to the first housing 24 relative to the first housing 24 in the X-axis direction, the second housing 26 drives the support device 22 to slide and curl relative to the second housing 26, and the sliding area 54 curls synchronously with the support device 22, thereby reducing the volume of the housing 20. When the sliding area 54 is unfolded, it can increase the display surface of the flexible screen 50, making it more convenient for users to use; when the sliding area 54 is rolled up, it can reduce the size of the electronic device 100, making it more portable.

[0054] In this invention, the "front side" refers to the side facing the same direction as the light-emitting surface of the flexible screen 50, and the "back side" refers to the side facing the opposite direction to the light-emitting surface of the flexible screen 50. The first direction is the sliding direction of the second housing 26 relative to the first housing 24, i.e., the first direction is the X-axis direction; the second direction is parallel to the folding axis of the support device 22, i.e., the second direction is the Y-axis direction; and the third direction is the thickness direction of the electronic device 100, i.e., the third direction is the Z-axis direction. The electronic device 100 also includes a motherboard and power supply, etc., disposed within the housing 20. The motherboard is electrically connected to the flexible screen 50 and the power supply, which supplies power to the flexible screen 50 and the motherboard.

[0055] like Figures 10-17 As shown, the support device 22 includes a plurality of support rods 220 connected in sequence. Each support rod 220 has a first guide bend 221 and a second guide bend 223 on opposite sides. Two adjacent support rods 220 are rotatably connected by the cooperation of the first guide bend 221 and the second guide bend 223. Each support rod 220 also has a first abutment 224 and a second abutment 226 on opposite sides. When the plurality of support rods 220 are in a flattened state, two adjacent support rods 220 abut against each other by the cooperation of the first abutment 224 and the second abutment 226. In this embodiment, each support rod 220 has a first guide bend 221 and a second guide bend 223 on opposite sides, and each support rod 220 also has a first abutment 224 and a second abutment 226 on opposite sides. When two adjacent support rods 220 rotate relative to each other, the first guide bend 221 and the corresponding second guide bend 223 rotate relative to each other, and the first abutment 224 and the corresponding second abutment 226 abut against each other. Specifically, one side of the support rod 220 has at least one first guide bend 221 and at least one second abutment 226, and the other side of the support rod 220 has at least one second guide bend 223 and at least one first abutment 224. The first guide bend 221 and the second guide bend 223 of the support rod 220 face each other along the first direction (i.e., the X-axis direction), and the first abutment 224 and the second abutment 226 of the support rod 220 face each other along the first direction (i.e., the X-axis direction). In this embodiment, one side of the support rod 220 is provided with two first guide bends 221 and two second abutments 226, and the other side of the support rod 220 is provided with two second guide bends 223 and two first abutments 224. The two first guide bends 221 are respectively opposite to the two second guide bends 223 along the first direction (X-axis direction), and the two first abutments 224 are respectively opposite to the two second abutments 226 along the first direction (X-axis direction). The two first guide bends 221 of each pair of adjacent support rods 220 are rotatably connected to the corresponding second guide bends 223, and the two first abutments 224 are rotatably abutting against the corresponding second abutments 226.

[0056] In other embodiments, one side of the support rod 220 is provided with three or more first guide bends 221 and three or more second abutments 226, and the opposite side of the support rod 220 is provided with three or more second guide bends 223 and three or more first abutments 224. The three or more first guide bends 221 correspond one-to-one with the three or more second guide bends 223 along the first direction (X-axis direction), and the three or more first abutments 224 correspond one-to-one with the three or more second abutments 226 along the first direction (X-axis direction). The three or more first guide bends 221 of each pair of adjacent support rods 220 are rotatably connected to the corresponding second guide bends 223, and the three or more first abutments 224 are rotatably abutting against the corresponding second abutments 226.

[0057] In this application, the support device 22 of the electronic device 100 is slidably mounted around the second housing 26, and the sliding area 54 of the flexible screen 50 is attached to the surface of the support device 22 away from the second housing 26. During the sliding process of the second housing 26 relative to the first housing 24, the sliding area 54 slides around the second housing 26 with the support device 22. Since the first guide bend 221 of each two adjacent support rods 220 is rotatably connected to the corresponding second guide bend 223, and the first abutment 224 of each two adjacent support rods 220 is rotatably abutted to the corresponding second abutment 226, the support rods 220 are prevented from rotating randomly, so that the multiple support rods 220 of the support device 22 become a whole, making it difficult for the support rods 220 and the flexible screen 50 to separate, and the support rods 220 exert a pulling force on the flexible screen 50, which can prevent the sliding area 54 of the flexible screen 50 from arching during the sliding or unfolding process, thereby preventing damage to the flexible screen 50.

[0058] like Figures 2-9As shown, the first housing 24 includes a fixed frame 240 and a first cover 245 connected to the front of the fixed frame 240. The fixed frame 240 includes a top wall 241, first end walls 242 located at opposite ends of the top wall 241, and first side walls 243 connected to the same end of the two first end walls 242. The top wall 241, the two first end walls 242, and the first side walls 243 form a first receiving space 244. The first receiving space 244 is used to house the second housing 26, the motherboard, and power supply components. A positioning groove 2401 is provided on the front of the fixed frame 240, and the first cover 245 is positioned in the positioning groove 2401. The fixed frame 240 and the first cover 245 are fixedly connected by a snap-fit ​​post and a snap-fit ​​hole. The snap-fit ​​post is located in one of the fixed frame 240 and the first cover 245, and the snap-fit ​​hole is located in the other of the fixed frame 240 and the first cover 245. The top wall 241 has guide grooves 2412 at opposite ends on its back surface. The guide grooves 2412 extend along a first direction (i.e., the X-axis direction), with one end extending close to the first side wall 243 and the other end passing through the side of the top wall 241 opposite to the first side wall 243. The top wall 241 also has a first positioning groove 2414 and a second positioning groove 2415, both extending along the first direction (i.e., the X-axis direction). Specifically, the top wall 241 has a first positioning groove 2414 at opposite ends on its back surface, and a second positioning groove 2415 located between the two first positioning grooves 2414. A fixing part 2416 is provided on the side of the top wall 241 opposite to the first side wall 243.

[0059] The first cover 245 includes a first cover plate 2451. A snap-fit ​​groove 2453 is provided on the front side of the first cover plate 2451 away from the second housing 26. A plurality of spaced-apart guide protrusions 2455 are provided on the front side of the first cover plate 2451 near the second housing 26. Each guide protrusion 2455 extends along a first direction (i.e., the X-axis direction), and the plurality of guide protrusions 2455 are arranged along a second direction (i.e., the Y-axis direction). Each pair of adjacent guide protrusions 2455 forms a guide groove 2456, which extends along the first direction, and the plurality of guide grooves 2456 are arranged along the second direction (i.e., the Y-axis direction). The front side of the first cover plate 2451 is provided with several adhesive-receiving grooves 2457.

[0060] The second housing 26 is provided with guide grooves 2600, which include parallel straight guide grooves 2601 and curved grooves 2603 connecting the two straight guide grooves 2601. The straight guide grooves 2601 extend along the sliding direction (i.e., the X-axis direction) of the second housing 26 relative to the first housing 24, and the curved grooves 2603 are located at the end away from the first housing 24. The support device 22 is slidably arranged around the second housing 26 along the guide grooves 2600. When the second housing 26 slides relative to the first housing 24, the support device 22 moves along the guide grooves 2600. In this embodiment, the second housing 26 is provided with guide grooves 2600 at opposite ends, and the support device 22 is slidably accommodated in the two guide grooves 2600 at opposite ends. When the second housing 26 slides relative to the first housing 24, the support device 22 moves synchronously along the two guide grooves 2600 at opposite ends to achieve the flattening or curling of the support device 22. The second housing 26 includes a sliding frame 260, an end cap 263 connected to the side of the sliding frame 260 away from the first housing 24, and a second cover 265 connected to the front of the sliding frame 260; guide grooves 2600 are provided at opposite ends of the sliding frame 260.

[0061] like Figure 8 and Figure 9As shown, the sliding frame 260 includes a bottom wall 2604, second end walls 2605 located at opposite ends of the bottom wall 2604, and a second side wall 2606 located on the side of the bottom wall 2604 away from the first housing 24. The bottom wall 2604, the second side wall 2606, and the two second end walls 2605 form a second receiving space 2607. The second receiving space 2607 is used to receive the top wall 241 of the first housing 24 and electronic components such as the motherboard and power supply connected to the top wall 241. Positioning portions 2608 are respectively provided at opposite ends of the front side of the bottom wall 2604. The side of the second side wall 2606 facing away from the second receiving space 2607 is designed as an arc surface so that the support device 22 can be slidably wrapped around the second side wall 2606. The front side of the second side wall 2606 is provided with a plurality of positioning grooves 2609, which are arranged along the length direction of the second side wall 2606. The sliding frame 260 has a clearance space 2611 on the side of its bottom wall 2604 facing away from the second receiving space 2607. The support device 22 and the sliding roll area 54 are slidably accommodated in the clearance space 2611. A receiving area 2612 is provided between each second end wall 2605 and the second side wall 2606. The second housing 26 also includes two blocking blocks 2614, which are respectively positioned in the two receiving areas 2612 of the second housing 26. The end face of the blocking block 2614 facing away from the second end wall 2605 is set as an arc surface. When the blocking block 2614 is positioned in the receiving area 2612, the arc surface of the blocking block 2614 and the second side wall 2607 are perpendicular to each other. The arc surfaces of 606 are coaxial. In this embodiment, two straight guide grooves 2601 of the guide groove 2600 are located on opposite sides of the side of the second end wall 2605 facing the second receiving space 2607, and the curved groove 2603 of the guide groove 2600 is located on the side of the blocking block 2614 facing the second receiving space 2607. When the blocking block 2614 is positioned within the receiving area 2612, the two ends of the curved groove 2603 are respectively connected to the two straight guide grooves 2601. Each second end wall 2605 has a positioning hole 2613 at one end near the second side wall 2606. The blocking block 2614 has a fixing hole 2615 on the side facing away from the second side wall 2606.

[0062] The second housing 26 also includes a battery cover 267, which is connected to the back of the sliding frame 260. The battery cover 267 covers the clearance space 2611 of the sliding frame 260 to prevent the support device 22 and the sliding roll area 54 from being exposed.

[0063] An end cap 263 and a sliding frame 260 form a through groove. A support device 22 is wound around the sliding frame 260 and slidably passes through the through groove. Specifically, the end cap 263 includes a cover plate 2631 and connecting plates 2633 disposed at opposite ends of the cover plate 2631. The cover plate 2631 has an arc-shaped cross-section. The cover plate 2631 and the two connecting plates 2633 form a receiving space 2634. The receiving space 2634 is used to receive the side of the second housing 26 away from the first housing 24, as well as the support device 22 and the flexible screen 50 wound around the second sidewall 2606. Positioning holes 2636 are respectively formed in the middle of the two connecting plates 2633. The two connecting plates 2633 of the end cap 263 are respectively connected to the two second end walls 2605 of the sliding frame 260. Each connecting plate 2633 and the corresponding second end wall 2605 can be connected by means of, but not limited to, snap-fit, screw-fit, or adhesive bonding. In this embodiment, the connecting plate 2633 and the corresponding second end wall 2605 are fixedly connected by the cooperation of snap-fit ​​posts and snap-fit ​​holes. The snap-fit ​​posts can be provided in one of the connecting plate 2633 and the second end wall 2605, and the snap-fit ​​holes can be provided in the other of the connecting plate 2633 and the second end wall 2605. Specifically, the side of the connecting plate 2633 facing the corresponding second end wall 2605 is provided with snap-fit ​​posts 2637, and the second end wall 2605 is provided with snap-fit ​​holes corresponding to the snap-fit ​​posts 2637. The snap-fit ​​posts 2637 are snapped into the corresponding snap-fit ​​holes so that the end cap 263 is connected to the sliding frame 260.

[0064] The front of the second cover 265 is provided with a plurality of spaced-apart through grooves 2652. Each spaced-apart through groove 2652 extends along the sliding direction of the sliding frame 260 relative to the fixed frame 240, that is, the spaced-apart through groove 2652 extends along the X-axis direction. The plurality of spaced-apart through grooves 2652 are arranged along the Y-axis direction to form a plurality of guide slides 2654 on the second cover 265. Specifically, multiple clearance slots 2652 are arranged along the second direction (i.e., the Y-axis direction). Each clearance slot 2652 passes through the back of the second cover 265, and one end of the clearance slot 2652 passes through the side of the second cover 265 near the first housing 24. The other end of the clearance slot 2652 extends to the side away from the first housing 24, thereby forming multiple guide pieces 2654 on the second cover 265. The multiple guide pieces 2654 are arranged along the second direction (i.e., the Y-axis direction), and the multiple guide pieces 2654 correspond one-to-one with the multiple guide slots 2456 of the first cover 245. The second cover 265 and the sliding frame 260 are fixedly connected by means of snap-fit, screw-fit, or adhesive bonding. In this embodiment, the second cover 265 and the sliding frame 260 are fixedly connected by the cooperation of a positioning block and a positioning groove. The positioning block is provided on one of the second cover 265 and the sliding frame 260, and the positioning groove is provided on the other of the second cover 265 and the sliding frame 260. Specifically, a plurality of positioning blocks 2656 are provided on the side of the back of the second cover 265 away from the first housing 24. The plurality of positioning blocks 2656 are arranged at intervals along the Y-axis direction, and the plurality of positioning blocks 2656 correspond to the plurality of positioning grooves 2609 of the sliding frame 260.

[0065] The first housing 24 and the second housing 26 are slidably connected by a slide rail 271 and a slider 273. The slide rail 271 extends along the sliding direction (i.e., the X-axis direction) of the second housing 26 relative to the first housing 24. The slide rail 271 is located in one of the first housing 24 and the second housing 26, and the slider 273 is located in the other of the first housing 24 and the second housing 26. In this embodiment, the slide rail 271 is located in the second housing 26. Specifically, each of the two positioning parts 2608 of the sliding frame 260 is connected to a slide rail 271. The slider 273 is located in the first housing 24. Specifically, each of the two first positioning grooves 2414 of the fixed frame 240 is connected to a slider 273. When the first housing 24 and the second housing 26 are assembled, the two guide sliders 273 are slidably connected to the two guide slide rails 271.

[0066] In some embodiments, a guide rail 271 is provided in the first receiving space 244 of the first housing 24, extending along the X-axis direction, and a guide slider 273 is provided in the second receiving space 2607 of the second housing 26. When the first housing 24 and the second housing 26 are assembled together, the guide slider 273 is slidably connected to the guide rail 271. Preferably, the surface of the top wall 241 of the first housing 24 facing the first receiving space 244 is provided with two parallel and spaced guide rails 271, and the surface of the bottom wall 2604 of the second housing 26 facing the second receiving space 2607 is provided with two spaced guide sliders 273. When the first housing 24 and the second housing 26 are assembled together, the two guide sliders 273 are slidably connected to the two guide rails 271 respectively.

[0067] The first housing 24 and the second housing 26 are slidably connected by a rack 281 and a drive gear 283. The rack 281 extends along the sliding direction (i.e., the X-axis direction) of the second housing 26 relative to the first housing 24. The drive gear 283 rotatably meshes with the rack 281. The rack 281 is connected to one of the first housing 24 and the second housing 26, and the drive gear 283 is located in the other of the first housing 24 and the second housing 26. In this embodiment, the rack 281 is housed in the second receiving space 2607 of the sliding frame 260 and fixedly connected to the bottom wall 2604. The teeth of the rack 281 extend and are arranged along the sliding direction (i.e., the X-axis direction) of the second housing 26 relative to the first housing 24. The drive gear 283 is located in the first receiving space 244 of the first housing 24 and meshes with the rack 281. When the drive gear 283 rotates, it can drive the second housing 26 to slide relative to the first housing 24 through the rack 281. The drive gear 283 is driven to rotate by the drive component 285. In this embodiment, the drive component 285 is a motor connected to the fixed frame 240. The motor is electrically connected to the main board, and the drive gear 283 is fixedly sleeved on the drive shaft of the motor.

[0068] In other embodiments, rack 281 is housed in the first receiving space 244 of the first housing 24 and fixedly connected to the top wall 241. The teeth of rack 281 extend and are arranged along the sliding direction of the second housing 26 relative to the first housing 24. Drive member 285 and drive gear 283 are housed in the second receiving space 2607 of the second housing 260, and drive member 285 is fixedly connected to the bottom wall 2604. Drive gear 283 meshes with rack 281. When drive member 285 drives drive gear 283 to rotate, drive gear 283 can drive the second housing 26 to slide relative to the first housing 24 through rack 281.

[0069] like Figures 8-17As shown, the support device 22 includes a plurality of interconnected support rods 220, and adjacent support rods 220 can be flattened or bent relative to each other; each support rod 220 includes a rod body 222, a first guide bend 221 and a second abutment 226 disposed on one side of the rod body 222, and a second guide bend 223 and a first abutment 224 disposed on the opposite side of the rod body 222. The first guide bend 221 and the second guide bend 223 on each rod body 222 are arranged along a first direction (i.e., the X-axis direction), and the first abutment 224 and the second abutment 226 on each rod body 222 are arranged along a first direction (i.e., the X-axis direction); the first guide bend 221 and the second abutment 226 are arranged along a second direction (i.e., the Y-axis direction), and the second guide bend 223 and the first abutment 224 are arranged along a second direction (i.e., the Y-axis direction), and the first direction is perpendicular to the second direction. The first guide bend 221 and the second abutment 226 on one side of one support rod 220 are rotatably abutted against the second guide bend 223 and the first abutment 224 on one side of the adjacent support rod 220, respectively. That is, the first guide bend 221 on one side of one support rod 220 is rotatably connected to the second guide bend 223 on the other side of the support rod 220, and the second abutment 226 on one side of one support rod 220 is rotatably abutted against the first abutment 224 on the other side of the support rod 220. When two adjacent support rods 220 rotate relative to each other, the first guide bend 221 and the corresponding second guide bend 223 of the two adjacent support rods 220 rotate relative to each other, and the second abutment 226 and the corresponding first abutment 224 of the two adjacent support rods 220 rotate relative to each other, allowing the two adjacent support rods 220 to transmit force to each other, causing the support device 22 to bend or flatten, and preventing the support device 22 from arching. The support device 22 is slidably mounted around the second housing 26, and one side of the support device 22 is fixedly connected to the first housing 24. Specifically, the support rod 220 of the support device 22 near the first housing 24 is connected to the first housing 24.

[0070] In the electronic device 100 of the present invention, the second housing 26 is slidably connected to the first housing 24, the support device 22 is slidably wound around the second housing 26, and the support rod 220 on one side of the support device 22 is connected to the first housing 24. The positioning area 52 of the flexible screen 50 is positioned on the front side of the first housing 24, and the sliding area 54 of the flexible screen 50 is attached to the surface of the support device 22 opposite to the first housing 24. When the second housing 26 slides and extends or retracts relative to the first housing 24, the second housing 26 drives the support device 22 to slide and unfold or roll relative to the second housing 26, and the sliding area 54 unfolds or rolls with the support device 22. Since the sliding area 54 of the flexible screen 50 is connected to the second housing 26 via the support device 22, and adjacent support rods 220 in the support device 22 are rotatably connected by the cooperation of the first guide bend 221 and the second guide bend 223, and the first abutment 224 and the second abutment 226 are rotatably abutted against each other, during the rotation of the two adjacent support rods 220 relative to each other, the first guide bend 221 is rotatably connected to the second guide bend 223 and the first abutment 224 is rotatably abutted against the second abutment 226, so that there is a force transmitted between the two support rods 220, so that the support device 22 can move along the rolling trajectory. That is, the support device 22 can slide around the second housing 26 and unfold or roll up even without being in contact with the flexible screen 50. Therefore, the tension between the sliding area 54 of the flexible screen 50 and the support device 22 is small during the unfolding or rolling up process, which can prevent the flexible screen 50 from easily detaching from the support device 22 and arching up and being damaged.

[0071] like Figure 16 and Figure 17The rod 222 includes a front face 2221, a back face 2223 opposite to the front face 2221, two opposite sides 2225, and two opposite end faces 2226. One side of the rod 222 is provided with a first guide bend 221 and a second abutment 226, and the other side of the rod 222 is provided with a second guide bend 223 and a first abutment 224. In this embodiment, the rod body 222 has a first guide bend 221, a second guide bend 223, a first abutment 224, and a second abutment 226 at opposite ends. The two first guide bends 221 and the two second abutments 226 are located on one side of the rod body 222, and the two second guide bends 223 and the two first abutments 224 are located on the opposite side of the rod body 222. The first guide bends 221 and second guide bends 223 at the same end of the rod body 222 are directly opposite each other along the first direction (i.e., the X-axis direction), and the first abutments 224 and second abutments 226 at the same end of the rod body 222 are directly opposite each other along the first direction (i.e., the X-axis direction). The two first guide bends 221 and the corresponding second guide bends 223 of two adjacent support rods 220 rotate relative to each other, and the two first abutments 224 of two adjacent support rods 220 abut against the corresponding second abutments 226. Preferably, the front surface 2221 is an arc-shaped surface. In other embodiments, the front side 2221 may be provided with a plurality of dispensing grooves, which are arranged along the Y-axis direction. The dispensing grooves are used to contain adhesive so that the flexible screen 50 can be bonded to the support rod 220.

[0072] In this embodiment, the two second abutment points 226 on one side of the rod 222 are located between the two first guide bends 221, and the two first abutment points 224 on the other side of the rod 222 are located between the two second guide bends 223. That is, the first guide bends 221 at the same end of the rod 222 are closer to the end face 2226 of the rod 222 than the second abutment points 226, and the second guide bends 223 at the same end of the rod 222 are closer to the end face 2226 of the rod 222 than the first abutment points 224. In other embodiments, the two first guide bends 221 on one side of the rod 222 are located between the two second abutment points 226, and the two second guide bends 223 on the other side of the rod 222 are located between the two first abutment points 224. In other embodiments, the first guide bend 221 and the second abutment 226 on one side of the rod 222 are arranged alternately, and the second guide bend 223 and the first abutment 224 on the other side of the rod 222 are arranged alternately. Each first guide bend 221 and the corresponding second guide bend 223 are directly opposite each other in the first direction (i.e., the X-axis direction), and each first abutment 224 and the corresponding second abutment 226 are directly opposite each other in the first direction (i.e., the X-axis direction).

[0073] The first guide bend 221 includes a guide bend hook protruding from one side of the rod 222, and the second guide bend 223 includes a guide bend block 2231 with a guide bend hole 2230. The guide bend hook is closer to the front of the rod 222 than the guide bend block 2231. The guide bend hook of one support rod 220 is rotatably connected to the guide bend hole 2230 of an adjacent support rod 220, and the guide bend hook and the guide bend block 2231 are rotatably connected relative to each other. In this embodiment, the first guide bend 221 is located near the front 2221 of the rod 222, and the second guide bend 223 is located on the back 2223 of the rod 222. The guide hook includes a first extension segment 2212 extending from the front side 2221 of the rod 222 along a first direction (i.e., the X-axis direction) and a second extension segment 2214 extending from the end of the first extension segment 2212 away from the rod 222 along a third direction (i.e., the Z-axis direction); the guide hole 2230 passes through the guide block 2231 and the rod 222 along the third direction (Z-axis direction), that is, the guide hole 2230 passes through the front side 2221 of the rod 222 and the back side of the guide block 2231 along the third direction, and the front side 2221 of the rod 222... A first receiving opening 2232 is provided on the side opposite to the first guide bend 221. The first receiving opening 2232 communicates with the guide bend hole 2230 and passes through the side 2225 of the rod body 222 opposite to the first guide bend 221 to form a stop bar 2235 on the second guide bend 223. The stop bar 2235 includes a first stop surface 2235a facing the first receiving opening 2232 and a second stop surface 2235b facing the guide bend hole 2230. The first stop surface 2235a is connected to the second stop surface 2235b. The guide bend hook of one support rod 220 is rotatably connected to the corresponding stop bar 2235 of the adjacent support rod 220. Specifically, the first extension section 2212 and the second extension section 2214 of one support rod 220 are respectively rotatably accommodated in the first receiving opening 2232 and the guide bend hole 2230 of the adjacent support rod 220. In this embodiment, both the first extension segment 2212 and the second extension segment 2214 are rectangular plates, and the guide hole 2230 is a rectangular hole. The cross-sectional area of ​​the second extension segment 2214 parallel to the XY plane is smaller than the opening area of ​​the guide hole 2230, so that the first guide portion 221 is rotatably connected to the guide hole 2230 and the first guide portion 221 rotatably abuts against the second guide portion 223. The first extension segment 2212 includes a first abutting surface 2213 near the side of the second extension segment 2214, and the second extension segment 2214 includes a second abutting surface 2215 facing the first extension segment 2212. The first abutting surface 2213 and the second abutting surface 2215 are connected to each other.

[0074] When two adjacent support rods 220 are in a flattened state, the first extension 2212 of one support rod 220 abuts against the guide block of the adjacent support rod 220 in the third direction (i.e., the Z-axis direction), and the second extension 2214 of one support rod 220 abuts against the guide block of the adjacent support rod 220 in both the first direction (i.e., the X-axis direction) and the second direction (i.e., the Y-axis direction). Specifically, when two adjacent support rods 220 are in a flattened state, the first abutting surface 2213 of the first extension 2212 of one support rod 220 abuts against the first stop surface 2235a of the adjacent support rod 220 in the third direction (i.e., the Z-axis direction), and the second abutting surface 2215 of one support rod 220 abuts against the second stop surface 2235b of the adjacent support rod 220 in the first direction (i.e., the X-axis direction).

[0075] The first abutment 224 includes a first abutment block 2240 protruding from the other side of the rod 222, and the second abutment 226 includes a second abutment block 2260 protruding from one side of the rod 222. The first abutment block 2240 on the support rod 220 is closer to the front 2221 of the rod 222 than the second abutment block 2260, that is, the first abutment block 2240 is closer to the front 2221 of the rod 222, and the second abutment block 2260 is closer to the back 2223 of the rod 222. The first abutment block 2240 of one support rod 220 abuts against the second abutment block 2260 of the adjacent support rod 220, and the first abutment block 2240 of one support rod 220 and the second abutment block 2260 of the adjacent support rod 220 rotate relative to each other. In this embodiment, the first abutment block 2240 is located on the front of the rod 222, and the second abutment block 2260 is located on the back of the rod 222. The front of the rod 222 is provided with a second receiving opening 2262 corresponding to the second abutment block 2260. The second receiving opening 2262 passes through the side of the rod 222 away from the first abutment block 2240. The first abutment block 2240 of one support rod 220 is rotatably housed in the second receiving opening 2262 of an adjacent support rod 220, and the first abutment block 2240 rotatably abuts against the second abutment block 2260. When the multiple support rods 220 are in a flattened state, the first abutment block 2240 of one support rod 220 and the second abutment block 2260 of an adjacent support rod 220 abut against each other in the third direction (i.e., the Z-axis direction).

[0076] Preferably, the back surface of the first abutment block 2240 and / or the front surface of the second abutment block 2260 are curved surfaces, and the back surface of the first abutment block 2240 rotatably abuts against the front surface of the second abutment block 2260 to facilitate the folding or flattening of the two adjacent support rods 220. In some embodiments, the back surface of the first abutment block 2240 is curved, the front surface of the second abutment block 2260 is flat, and the back surface of the first abutment block 2240 rotatably abuts against the front surface of the second abutment block 2260; in some embodiments, the back surface of the first abutment block 2240 is flat, the front surface of the second abutment block 2260 is curved, and the back surface of the first abutment block 2240 rotatably abuts against the front surface of the second abutment block 2260. In some embodiments, the back side of the first abutment block 2240 is provided with an arc surface, and the front side of the second abutment block 2260 is provided with an arc surface, and the back side of the first abutment block 2240 rotatably abuts against the front side of the second abutment block 2260.

[0077] The support rod 220 also includes two connecting portions 225 connected to opposite ends of the back surface 2223 of the rod body 222, and a support portion 227 connected to the end of each connecting portion 225 away from the rod body 222, wherein one support portion 227 is located on the side of the corresponding connecting portion 225 away from the other support portion 227. Specifically, the connecting portion 225 extends along the Z-axis direction from the back surface 2223 of the rod body 222 near the end face 2226, and the width of the connecting portion 225 on the X-axis gradually decreases along the extension direction of the connecting portion 225, such that the width of the end of the connecting portion 225 connected to the rod body 222 extending along the X-axis direction is greater than the width of the end of the connecting portion 225 away from the rod body 222 extending along the X-axis direction; the support portion 227 extends along the Y-axis direction from the end of the connecting portion 225 away from the rod body 222 towards the end away from the first guide bend 221; preferably, the support portion 227 is a cylindrical column. In this embodiment, the back surface 2223 of the rod body 222 is provided with connecting portions 225 at opposite ends, and each connecting portion 225 is provided with a support portion 227 on the side away from the rod body 222 and opposite to the first guide bend portion 221. Preferably, the end face of the connecting portion 225 away from the rod body 222 is an arc surface, and the support portion 227 is a circular support column extending along the length direction of the rod body 222.

[0078] The support rod 220 also includes a rolling element 228, which is a roller rotatably fitted onto the support portion 227 (i.e., the support column). When the support rod 220 moves relative to the second housing 26, the rolling element 228 rolls into contact with the guide groove 2600, causing a rolling connection between the support rod 220 and the second housing 26. This reduces the frictional resistance between the support rod 220 and the second housing 26, facilitating the movement of the support device 22 around the second housing 26 along the guide groove 2600. In this embodiment, the rolling element 228 can be a rolling cylinder, and the axis of the rolling cylinder is collinear with the axis of the support portion 227. In other embodiments, the rolling element 228 may also be a ball bearing disposed on the side of the support portion 227 facing the rod body 222. The rolling element 228 may be, but is not limited to, a hard ball bearing such as a metal ball bearing. Specifically, a receiving groove is provided on the outer peripheral surface of the support portion 227, and the ball bearing is rotatably placed in the receiving groove, with part of the outer surface of the ball bearing exposed in the receiving groove. When the support rod 220 moves relative to the second housing 26, the ball bearing rolls into contact with the inner surface of the guide groove 2600, thereby creating a rolling connection between the support rod 220 and the second housing 26.

[0079] The front side 2221 of the rod body 222 has two opposite ends with baffles 229. The space between the two baffles 229 at both ends is used to accommodate the flexible screen 50. That is, the flexible screen 50 is attached to the front side 2221 and located between the two baffles 229. Specifically, the baffles 229 are baffles protruding from the front side 2221.

[0080] In this embodiment, the support rod 220 is made of liquid metal through injection molding. Specifically, the rod body 222, the first guide bend 221, the first abutment 224, the second guide bend 223, the second abutment 226, the connecting part 225, the support part 227, and the stop part 229 are integrally molded. This process is simple and the manufacturing cost is low. In other embodiments, the support rod 220 can also be made of other rigid materials.

[0081] When assembling each support rod 220 in this embodiment, two rolling elements 228 are rotatably sleeved on two support portions 227 respectively, so that each rolling element 228 can roll around the corresponding support portion 227.

[0082] Please refer to the following: Figures 10-27When assembling the support device 22, one of the support rods 220 is placed on one side of the other support rod 220, so that the rod bodies 222 of the two support rods 220 are parallel to each other. The first guide bend 221 of one support rod 220 is inserted into the corresponding guide bend hole 2230 of the other support rod 220, and the first abutment 224 of the other support rod 220 is inserted into the corresponding second receiving opening 2262 of one support rod 220 and abuts against the second abutment 226. Specifically, the second extension 2214 of the first guide bend 221 is inserted into the corresponding guide bend hole 2230, so that the first abutment surface 2213 abuts against the first stop surface 2235a, and the second abutment surface 2215 abuts against the second stop surface 2235b; the back of the first abutment block 2240 rotatably abuts against the front of the corresponding second abutment 226. Assemble all the support rods 220 into one unit according to the above assembly method, so that the support device 22 is a hinged whole. The first guide bend 221 on one side of each support rod 220 is rotatably connected to the corresponding second guide bend 223 of the adjacent support rod 220, and the first abutment 224 on the opposite side of each support rod 220 is rotatably attached to the corresponding second abutment 226 of the adjacent support rod 220. Each pair of adjacent support rods 220 are connected by the cooperation of the first guide bend 221 and the corresponding second guide bend 223, and the first abutment 224 and the corresponding second abutment 226, so that the bending or unfolding of the support device 22 is smooth and even, and the support rods 220 will not arch or detach from the support device. The support device 22 of the present invention can be assembled by interlocking the support rods 220 together without the need for tools, making installation convenient and quick, and reducing assembly costs. The support rods 220 of the support device 22 are assembled together by the cooperation of the first guide bend 221 and the corresponding second guide bend 223 of the adjacent support rods 220 to form a hinge-like integral structure, which is convenient and simple to assemble. Moreover, during the sliding or flattening process, each pair of adjacent support rods 220 transmits force to each other, enabling the support device 22 to achieve smooth sliding or flattening.

[0083] like Figures 27-30As shown, when two adjacent support rods 220 are connected to each other, the first guide bend 221 of one support rod 220 is rotatably connected to the second guide bend 223 of the other support rod 220, and the first abutment 224 of the other support rod 220 is rotatably attached to the second abutment 226 of one of the support rods 220. When the two adjacent support rods 220 are flattened, the front faces 2213 of the two support rods 220 are coplanar. The first abutment surface 2213 of the first guide bend 221 of each support rod 220 abuts against the first stop surface 2235a of the second guide bend 223 of the adjacent support rod 220, and the second abutment surface 2215 abuts against the second stop surface 2235b. The back of the first abutment block 2240 rotatably abuts against the front of the corresponding second abutment 226 to prevent the two adjacent support rods 220 from reversing. When two adjacent support rods 220 bend, the front faces 2221 of the two support rods 220 bend towards each other, the second extension 2214 of each first guide bend portion 221 rotates in the corresponding guide bend hole 2230, the inner surface of the first extension 2212 of the first guide bend portion 221 abuts against the first stop surface 2235a of the corresponding second guide bend portion 223, and the first stop 224 abuts against the corresponding second stop 226, so as not to hinder the mutual bending of the two support rods 220.

[0084] The two adjacent support rods 220 only change between a flattened state and a bent state. When the two support rods 220 are flattened, the first abutting surface 2213 of the first guide bending part 221 abuts against the first stop surface 2235a of the corresponding second guide bending part 223, and the back of the first abutting top 224 abuts against the front of the corresponding second abutting top 226, so that the two support rods 220 are positioned relative to each other in the Z-axis direction; the second abutting surface 2215 of the first guide bending part 221 abuts against the second stop surface 2235b of the corresponding second guide bending part 223, so that the two support rods 220 are positioned relative to each other in the X-axis direction; the second extension 2214 of the first guide bending part 221 is inserted into the guide bending hole 2230 of the corresponding second guide bending part 223, so that the two support rods 220 are positioned relative to each other in the Y-axis direction. Therefore, when the two adjacent support rods 220 are in a flattened state, they can be positioned in the X-axis, Y-axis, and Z-axis directions, maintaining a stable flattened state and improving their flatness, thus preventing them from bending backwards. When the two support rods 220 bend towards each other, the first abutting surface 2213 and the second abutting surface 2215 of the first guide bending portion 221 separate from the first stop surface 2235a and the second stop surface 2235b of the corresponding second guide bending portion 223, allowing the two support rods 220 to bend towards each other; the inner surface of the first extension 2212 of the first guide bending portion 221 abuts against the first stop surface 2235a of the corresponding second guide bending portion 223, and the first abutting top 224 abuts against the corresponding second abutting top 226, allowing the two support rods 220 to bend or flatten together.

[0085] Please refer to the following: Figures 1-9When assembling the electronic device 100, the back of the first cover 245 is fixedly connected to the front of the fixed frame 240; two guide rails 271 are placed parallel and spaced apart in the second receiving space 2607 of the second housing 26 and positioned in the two positioning parts 2608; two guide sliders 273 are placed spaced apart in the first receiving space 244 of the first housing 24 and positioned in the two first positioning grooves 2414 respectively; a rack 281 is placed in the second receiving space 2607 of the second housing 260 and positioned on the bottom wall 2604, the rack 281 extending along the X-axis direction, and the drive member 285 is fixedly connected to the first housing 24; multiple positioning blocks 2656 of the second cover 265 are respectively engaged with the sliding frame 260. Multiple positioning slots 2609 are provided to connect the second cover 265 to the sliding frame 260; the second housing 26 is slidably inserted into the first receiving space 244 of the first housing 24, and the two guide sliders 273 on the first housing 24 are slidably connected to the two guide rails 271 of the second housing 26, the drive gear 283 meshes with the rack 281, and multiple guide plates 2654 are slidably inserted into multiple guide grooves 2456; the back side of the sliding area 54 of the flexible screen 50 is connected to the support device 22 through an adhesive layer. Specifically, a connecting adhesive is applied to the front side of the support rod 220, and then the back side of the sliding area 54 is attached to the front side of the support rod 220 so that the flexible screen 50 is glued to the support device 22.At this time, the rotation axis between two adjacent support rods 220 of the support device 22 is located in the adhesive layer; the positioning area 52 of the flexible screen 50 is housed in the positioning groove 2401 of the first housing 24, and the back of the positioning area 52 is fixedly attached to the front of the first cover 245, the positioning strip 521 is snapped into the snap-fit ​​groove 2453 of the first cover 245, and glue is placed in the glue-containing groove 2457 of the first cover 245, so that the positioning area 52 and the first cover 245 are fixedly connected by glue; The side of the support device 22 facing away from the flexible screen 50 surrounds the second housing 26, that is, the support device 22 and the sliding area 54 together surround the second side wall 2606 and bottom wall 2604 of the second housing 26; the support rod 220 of the support device 22 near the positioning area 52 is connected to the first housing 24, and the support rod 220 of the support device 22 away from the positioning area 52 is slidably connected to the second housing 26 through an end connector, and the rolling element 228 of the support rod 220 is slidably accommodated in the corresponding straight guide groove 2. In step 601, two blocking blocks 2614 are respectively positioned within two receiving areas 2612 of the second housing 26, such that the curved guide groove 2603 and the outer surface of the second side wall 2606 are coaxial, and the rolling element 228 at the bend of the support device 22 is rotatably accommodated in the corresponding curved groove 2603; the cover plate 2631 of the end cap 263 covers the sliding roll area 54 on the side of the second housing 26 away from the first housing 24, and the snap-fit ​​posts 2637 of the two connecting plates 2633 are respectively snapped into the opposite side. In the corresponding positioning hole 2613, two connecting plates 2633 respectively cover two blocking blocks 2614. The positioning hole 2636 on each connecting plate 2633 corresponds to the corresponding fixing hole 2615. Two fasteners, such as screws, pass through the two positioning holes 2636 and are locked into the corresponding fixing holes 2615, so that the end cap 263 is fixedly connected to the second housing 26. The flexible screen support device 22 and the flexible screen 50 surrounding the second side wall 2606 are slidably accommodated in the receiving space 2634.

[0086] At this time, the connecting part 225, the supporting part 227, the first guide bend 221, the second guide bend 223, the first abutment 224, and the second abutment 226 of the supporting device 22 are all located near the end face of the supporting rod 220, rather than being directly disposed at the end face of the supporting rod 220. Therefore, the connecting part 225, the supporting part 227, the first guide bend 221, the second guide bend 223, the first abutment 224, and the second abutment 226 avoid occupying the space on opposite sides of the housing 20. In addition, the guide groove 2600 is disposed on the side of the second end wall 2605 and the shielding block 2614 facing the second receiving space 2607, and the two connecting plates 2633 of the end cover 263 are respectively connected to the two second end walls 2605 of the second housing 260, which not only prevents external dust and debris from entering. The interior of the housing 20, and the connection part 225, support part 227, first guide bend part 221 and second guide bend part 223 are not exposed, improving the overall appearance of the electronic device 100. In addition, the rotation axis between each pair of adjacent support rods 220 is located on the adhesive layer of the support rod 220, and the first abutment 224 and the corresponding second abutment 226 of each pair of adjacent support rods 220 can rotate against each other to prevent the support rods 220 from rotating randomly, so that the multiple support rods 220 of the support device 22 become a whole, and the support rods 220 and the flexible screen 50 are not easily separated, avoiding the arching of the sliding area 54 of the flexible screen 50 during sliding or unfolding, thereby ensuring that the connection between the flexible screen 50 and the flexible screen support device 22 is stable and firm, and preventing damage to the flexible screen 50.

[0087] like Figures 1-9 and Figures 28-31 As shown, the unfolding process of the flexible screen 50 of the electronic device 100 is as follows: the first housing 24 and / or the second housing 26 are pulled by an external force (such as the user's pulling force), causing the first housing 24 and the second housing 26 to slide away from each other. The guide slide 2654 slides away from the first housing 24 along the corresponding guide slide groove 2456, and the guide slide 273 slides away from the second housing 26 on the corresponding guide slide rail 271. The sliding frame 260 slides relative to the support device 22, causing the support device 22 to unfold, and the support device 22 slides around the second housing 26. Specifically, the support rod 220 attached to the second bottom wall 2623 is first bent and then flattened on the outer side of the second side wall 2606 and slides to the front of the second cover 265. The support rod 220 of the support device 22 moves away from the first housing 24 until the sliding roll area 54 is fully unfolded with the support device 22.

[0088] Please refer to the following as well: Figures 1-9 and Figures 32-39The rolling process of the flexible screen 50 of the electronic device 100 is as follows: the first housing 24 and / or the second housing 26 are pushed by an external force (such as the user's push), so that the first housing 24 and the second housing 26 slide towards each other and contract. The guide slide 2654 slides along the corresponding guide groove 2456 and approaches the first housing 24. The guide slide 273 slides on the corresponding guide rail 271. The sliding frame 260 slides relative to the support device 22, so that the support device 22 rolls up and slides around the second housing 26. Specifically, the support rod 220 attached to the second cover 265 bends and then flattens on the outer side of the second side wall 2606 and slides to the back of the bottom wall 2604. The support rod 220 of the support device 22 away from the first housing 24 slides towards the first housing 24 until the rolling area 54 is completely rolled up with the support device 22.

[0089] During the unfolding or rolling process of the flexible screen 50, each pair of adjacent support rods 220 transmits force through the cooperation of the first guide bend 221 and the second guide bend 223, and through the cooperation of the first abutment 224 and the second abutment 226, making the multiple support rods 220 of the support device 22 a whole. The support device 22 only flattens or bends along the guide groove 2600, preventing the flexible screen 50 from detaching from the support device 22 and arching up, thus protecting the flexible screen 50 and improving its reliability. The rolling element 228 makes rolling contact with the corresponding guide groove 2600, resulting in low frictional resistance of the support device 22 relative to the guide groove 2600, facilitating the unfolding of the support device 22 and the flexible screen 50. Due to the second sidewall 2606 The outer surface of the support device 22 is an arc surface, and the outer surface of the second sidewall 2606 is coaxial with the bending guide groove 2603, which facilitates the bending of the support device 22 along the outer surface of the second sidewall 2606. Each pair of adjacent support rods 220 are connected by the cooperation of the first guide bending part 221 and the second guide bending part 223, so that the bending and unfolding of the support device 22 is smooth and even. After each pair of adjacent support rods 220 are unfolded after passing the outer surface of the second sidewall 2606, the first abutment top 224 and the second abutment top 226 abut against each other for positioning, which can prevent the two support rods 220 from bending in the opposite direction, so as to ensure that the two support rods 220 have stable flatness to provide stable support for the flexible screen 50, and can prevent the support rods 220 from bending in the opposite direction and arching the flexible screen 50, effectively protecting the flexible screen 50.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
