Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and in particular to a support device for supporting a flexible screen, a housing provided with the support device, and an electronic device provided with the housing. Background Technology

[0002] With the development and application of flexible screens, rollable screen phones have emerged in existing technologies. These phones use a support structure to support the flexible screen, which is fixedly connected to the support structure to form a whole. The size of the phone screen is changed by rolling the flexible screen. However, in existing technologies, the support structure relies on the flexible screen to transmit force during the rolling process to allow the support structure and the flexible screen to unfold or roll together. Therefore, the flexible screen is subjected to significant forces during unfolding or rolling, making it susceptible to damage. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide a support device for preventing creases in a flexible screen, the support device enabling the flexible screen to unfold or retract. The present invention also provides a housing equipped with the above-described support device, and an electronic device equipped with the above-described housing.

[0004] This invention provides a support device comprising a plurality of interconnected first support rods. Each first support rod includes a first rod body, a guide bend portion disposed on one side of the first rod body, and a guide bend groove disposed on the opposite side of the first rod body. The guide bend portion of one first support rod is rotatably inserted into the guide bend groove of an adjacent first support rod. When two adjacent first support rods rotate relative to each other, the guide bend portion slides against the inner surface of the corresponding guide bend groove.

[0005] This invention also provides a housing, which includes a support device, a first housing, and a second housing. The first housing and the second housing are slidably connected to each other. The support device is slidably mounted around the second housing, and one side of the support device is 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.

[0007] In the support device of the electronic device of the present invention, two adjacent first support rods are rotatably connected by a guide fold portion and a guide fold groove. During the rotation of the two adjacent first support rods relative to each other, the guide fold portion slides against the inner surface of the guide fold groove to enable mutual force transmission between the two first support rods, allowing the support device to move along a curling trajectory. Therefore, the flexible screen attached to the flexible support device can unfold or curl with the flexible support device. The flexible screen is not easily damaged after multiple curlings, does not affect the appearance, and can improve the user experience. Moreover, the flexible screen is subjected to less force during unfolding or curling, which can further protect the flexible screen and improve its reliability. Attached Figure Description

[0062] Please refer to the following: Figures 1-6The 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 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 facing 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 rolls around the second housing 26, and the rolling area 54 rolls 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 a 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 rolling 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 a second 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 rolling 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 increases the display surface of the flexible screen 50, making it more convenient for users; when the sliding area 54 is rolled up, it reduces the size of the electronic device 100, making it easier to carry. 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 opposite to the second direction; the X-axis direction refers to the sliding direction of the second housing 26 relative to the first housing 24; the Z-axis direction refers to the thickness direction of the electronic device 100; and the Y-axis direction refers to the direction perpendicular to both the X-axis and Z-axis directions. 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 provides power to the flexible screen 50 and the motherboard.

[0063] like Figures 2-3 and Figure 5As shown, the first housing 24 includes a first top wall 241, a first bottom wall 243 opposite to the first top wall 241, a first side wall 245 connected to the same side of the first top wall 241 and the first bottom wall 243, and two opposing first end walls 246; the first top wall 241, the first bottom wall 243, the first side wall 245 and the two first end walls 246 form a first receiving space 247; the first receiving space 247 is used to house the second housing 26, the motherboard and power supply and other components. The front of the first housing 24 is provided with a positioning groove 2410, and the positioning area 52 of the flexible screen 50 is positioned in the positioning groove 2410. The first housing 24 has a plurality of guide grooves 2411 spaced apart on the bottom surface of the positioning groove 2410 away from the first sidewall 245. The plurality of guide grooves 2411 are arranged along the length direction of the first housing 24, that is, the plurality of guide grooves 2411 are arranged along the Y-axis direction. Each guide groove 2411 is connected to the positioning groove 2410. Specifically, the plurality of guide grooves 2411 are located on the surface of the first top wall 241 away from the first bottom wall 243 and away from the first sidewall 245. The plurality of guide grooves 2411 are arranged along the length direction of the first top wall 241, and each guide groove 2411 extends along the length direction perpendicular to the first top wall 241; that is, the plurality of guide grooves 2411 are arranged along the Y-axis direction and each guide groove 2411 extends along the X-axis direction. A connecting groove 2413 is provided on the first sidewall 245 near the first top wall 241. The connecting groove 2413 connects to the positioning groove 2410. The two ends of the connecting groove 2413 extend along the Y-axis to near the two first end walls 246, and the connecting groove 2413 is used to position the positioning strip 521 of the flexible screen 50. The two ends of the first housing 24 are provided with guide grooves 2415. The guide grooves 2415 extend along the length direction of the guide groove 2411 (i.e., along the X-axis) to near the first sidewall 245. The second housing 26 is slidably connected to the guide grooves 2415. Specifically, guide grooves 2415 are provided between the two ends of the first top wall 241 and the two first end walls 246. Preferably, the outer surface of the first sidewall 245 is an arc surface.

[0064] like Figure 2 and Figure 3As shown, the second housing 26 has a guide rail 260 on its side, and the support device 22 is slidably wound around the guide rail 260. When the second housing 26 slides relative to the first housing 24, the support device 22 moves around the guide rail 260. In this embodiment, the second housing 26 has guide rails 260 at opposite ends, and the support device 22 is slidably wound around the two guide rails 260 at opposite ends. When the second housing 26 slides relative to the first housing 24, the support device 22 moves synchronously around the two guide rails 260 at opposite ends to achieve the flattening or curling of the support device 22. The second housing 26 includes a sliding frame 262, a blocking member 265 connected to the end of the sliding frame 262, and an end cap 267 connected to the side of the sliding frame 262 away from the first housing 24. The guide rail 260 is located on the side of the blocking member 265 facing the sliding frame 262. In this embodiment, the sliding frame 262 is connected to two opposite ends with blocking members 265, and each blocking member 265 has a guide rail 260 on its side facing the sliding frame 262. In other embodiments, the guide rail 260 may also be provided at the end of the sliding frame 262. Preferably, the sliding frame 262 is provided with guide rails 260 at opposite ends.

[0065] like Figure 3As shown, the sliding frame 262 includes a second top wall 2621, a second bottom wall 2623 opposite to the second top wall 2621, a second side wall 2625 connected to the same side of the second top wall 2621 and the second bottom wall 2623, and two opposing second end walls 2626; the second top wall 2621, the second bottom wall 2623, the second side wall 2625 and the two second end walls 2626 form a second receiving space 2627. The front of the second housing 26 is provided with a plurality of spaced-apart recesses 2622. Each recess 2622 extends along the sliding direction of the second housing 26 relative to the first housing 24, that is, the recess 2622 extends along the X-axis direction. The plurality of recesses 2622 are arranged along the Y-axis direction to form a plurality of guide rods 2624 on the second housing 26. Specifically, the plurality of recesses 2622 are located on the second top wall 2621, and the plurality of recesses 2622 are arranged along the length direction of the second top wall 2621 (that is, along the Y-axis direction). Each clearance groove 2622 penetrates the second top wall 2621, with one end extending close to the second side wall 2625. The opposite end of the clearance groove 2622 penetrates the side of the second top wall 2621 away from the second side wall 2625, thereby forming multiple guide rods 2624 on the second top wall 2621. The multiple guide rods 2624 are arranged along the length direction of the second top wall 2621 (i.e., along the Y-axis direction), and each of the multiple guide rods 2624 corresponds one-to-one with a multiple guide groove 2411 of the first housing 24. The outer surface of the second side wall 2625 is set as an arc surface, that is, the outer surface of the second side wall 2625 away from the first housing 24 is set as an arc surface, so as to facilitate the sliding of the support device 22 around the second housing 26. A slider 2628 is provided at the end of the second end wall 2626 away from the second side wall 2625. The slider 2628 is used to slide into the corresponding guide groove 2415 of the first housing 24. A connecting strip 2629 protrudes from the middle of the second end wall 2626 towards the side opposite to the second receiving space 2627. The connecting strip 2629 extends along the length direction (i.e., the X-axis direction) of the second end wall 2626. Multiple connecting holes and snap-fit ​​holes are spaced apart on the connecting strip 2629. The multiple connecting holes are arranged along the length direction (i.e., the X-axis direction) of the connecting strip 2629, with one connecting hole located at the end of the connecting strip 2629 near the second side wall 2625. Preferably, the end face of the connecting strip 2629 near the second side wall 2625 has an arc surface to facilitate the sliding of the support device 22 around the second housing 26.

[0066] The shielding component 265 includes a shielding plate 2651, which is a rectangular plate. The end face of the rectangular plate away from the first housing 24 is set as an arc surface. The side of the shielding plate 2651 facing the sliding frame 262 is provided with a U-shaped groove 2653. The U-shaped groove 2653 extends along the edge of the shielding plate 2651, and the two ends of the U-shaped groove 2653 pass through the end face of the shielding plate 2651 away from the arc surface, thereby forming a U-shaped guide rail 260 on the shielding plate 2651. The guide rail 260 includes two straight guide rails 2601 spaced apart and a curved guide rail 2603 connected between the two straight guide rails 2601. The curved guide rail 2603 is located at one end away from the first housing 24. The two opposite ends of the curved guide rail 2603 are respectively connected to the ends of the two straight guide rails 2601. The curved guide rail 2603 and the straight guide rail 2601 are smoothly transitioned. The support device 22 is slidably wound around the guide rail 260. The shielding member 265 has a plurality of through holes 2655 spaced apart and a snap-fit ​​block 2656 in the middle. The plurality of through holes 2655 are arranged along the length direction (i.e., the X-axis direction) of the shielding member 2651, and one of the through holes 2655 is close to the curved guide rail 2603.

[0067] The end cap 267 includes a cover plate 2671 and connecting plates 2673 disposed at opposite ends of the cover plate 2671. The cover plate 2671 has an arc-shaped cross-section. The cover plate 2671 and the two connecting plates 2673 form a receiving space 2674. The receiving space 2674 is used to receive the side of the second housing 26 away from the first housing 24 and the support device 22 and flexible screen 50 wrapped around the second side wall 2625. Positioning holes 2676 are respectively formed in the middle of the two connecting plates 2673.

[0068] The first housing 24 and the second housing 26 are slidably connected by a guide rail 271 and a guide slider 273. The guide rail 271 is located in one of the first housing 24 and the second housing 26, and the guide slider 273 is located in the other. In this embodiment, the first receiving space 247 of the first housing 24 is provided with two parallel and spaced guide rails 271, which extend in a direction parallel to the guide groove 2411 (i.e., the X-axis direction). The second receiving space 2627 of the second housing 26 is provided with two spaced guide sliders 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 rails 271 respectively. Specifically, both guide rails 271 are connected to the first bottom wall 243 of the first housing 24, and both guide sliders 273 are connected to the second bottom wall 2623 of the second housing 26.

[0069] In some embodiments, the second receiving space 2627 of the second housing 26 is provided with a guide rail 271, which extends along the length direction (i.e., the X-axis direction) parallel to the guide rod 2624. The first receiving space 247 of the first housing 24 is provided with a guide slider 273. 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 second bottom wall 2623 of the second housing 26 facing the second receiving space 2627 is provided with two parallel and spaced guide rails 271, and the first bottom wall 243 of the first housing 24 facing the first receiving space 247 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.

[0070] The support device 22 includes a plurality of interconnected first support rods 220, which can be flattened or bent relative to each other. Each first support rod 220 includes a first rod body 221, a guide bending portion 223 on one side of the first rod body 221, and a guide bending groove 225 on the opposite side of the first rod body 221. Adjacent first support rods 220 are rotatably connected via the cooperation of the guide bending portion 223 and the guide bending groove 225. When adjacent first support rods 220 rotate relative to each other, the guide bending portion 223 slides against the inner surface of the corresponding guide bending groove 225, allowing the adjacent first support rods 220 to transmit force to each other, thereby bending or flattening the support device 22. 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 first support rod 220 of the support device 22 closest to the first housing 24 is connected to the first housing 24.

[0071] 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 first 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 the two adjacent first support rods 220 in the support device 22 are rotatably connected by the cooperation of the guide fold 223 and the guide fold groove 225, during the rotation of the two adjacent first support rods 220 relative to each other, the guide fold 223 slides against the inner surface of the guide fold groove 225, so that there is a force transmitted between the two first support rods 220, so that the support device 22 can move along the curling trajectory. That is, the support device 22 can slide around the second housing 26 to unfold or curl even without being in contact with the flexible screen 50. Therefore, the sliding area 54 of the flexible screen 50 is subjected to less force during the unfolding or curling process with the support device 22, which can prevent damage to the flexible screen 50.

[0072] Please refer to the following: Figures 6-15 The first rod 221 includes a front face 2211, a back face 2213 opposite to the front face 2211, two opposite side faces 2215, and two opposite end faces 2216. A guide fold 223 and a guide fold groove 225 are located on the back face 2213. Preferably, the opposite sides of the front face 2211 are arc-shaped surfaces. Preferably, the front face 2211 has multiple adhesive grooves 2217 arranged along the length direction (Y-axis direction) of the first rod 221. The adhesive grooves 2217 are used to collect adhesive so that the flexible screen 50 can be bonded to the first support rod 220. The front face 2211 of the first rod 221 has two opposite ends with baffles 2218. The space between the two baffles 2218 at each end is used to accommodate the flexible screen 50, meaning the flexible screen 50 is attached to the front face 2211 and located between the two baffles 2218. Specifically, the baffles 2218 are baffles protruding from the front face 2211.

[0073] The guide bend 223 includes two opposing first arc surfaces 2230, which are coaxial. The inner surface of the guide bend groove 225 includes two spaced second arc surfaces 2250, which are parallel to each other and coaxial. The axis of the first arc surface 2230 is parallel to the axis of the second arc surface 2250. When the guide bend 223 of one of the first support rods 220 is inserted into the guide bend groove 225 of the adjacent first support rod 220, the two first arc surfaces 2230 of the guide bend 223 of one of the first support rods 220 slide against each other with the two second arc surfaces 2250 of the other first support rod 220. At this time, the first arc surfaces 2230 and the second arc surfaces 2250 are coaxial, and there is a mutual abutting force between the first arc surfaces 2230 and the second arc surfaces 2250. Specifically, the guide bend 223 is an arc-shaped lug. The guide bend 223 extends from one side 2215 near the first rod 221 towards the other side 2215 and towards the front 2211. The middle part of the guide bends away from the first rod 221. Two first arc surfaces 2230 are respectively provided on opposite sides of the lug. The guide bend 223 includes an end 2231 and a connecting end 2233 located at its opposite ends, and an arc segment 2235 connecting the end 2231 and the connecting end 2233. The arc segment 2235 bends away from the first rod 221. The connecting end 2233 is used to connect to the first rod 221, and the end 2231 is farther away from the first rod 221 than the connecting end 2233. The guide groove 225 is an arc-shaped groove. The middle part of the guide groove 225 bends away from the first rod 221. The guide groove 225 includes an open end 2251, a closed end 2253, and an arc-shaped connecting section 2255 connecting the open end 2251 and the closed end 2253. The closed end 2253 is closer to the first rod 221 than the open end 2251, and the connecting section 2255 bends away from the first rod 221. Specifically, the two inner surfaces of the guide groove 225 are two second arc surfaces 2250.

[0074] The first support rod 220 further includes a connecting portion 226 disposed on the back surface 2213 of the first rod body 221. The connecting portion 226 is located near the end face 2216 of the first rod body 221. A guide bend portion 223 protrudes from one side of the connecting portion 226. Two first arc surfaces 2230 are respectively disposed on the side of the guide bend portion 223 facing the back surface 2213 and the other side away from the back surface 2213. A guide bend groove 225 is disposed on the side of the connecting portion 226 away from the guide bend portion 223. Preferably, the connecting portion 226 is a connecting piece protruding from the back surface 2213. The connecting piece is perpendicular to the length direction of the first rod body 221, that is, the connecting portion 226 extends along the Z-axis direction. The guide bend portion 223 protrudes from one side of the connecting piece, and the guide bend groove 225 is formed on the opposite side of the connecting piece.

[0075] In this embodiment, each first support rod 220 includes two connecting portions 226, which are respectively located at opposite ends of the back surface 2213 of the first rod body 221. Specifically, the two connecting portions 226 are located near the two opposite end faces 2216 of the first rod body 221. On the same side of the first rod body 221, one connecting portion 226 is provided with a guide bend 223, and the other connecting portion 226 is provided with a guide bend groove 225. Specifically, on the same side of the two connecting portions 226 near one of the side faces 2215, one connecting portion 226 is provided with a guide bend 223, and the other connecting portion 226 is provided with a guide bend groove 225; on the same side of the two connecting portions 226 near the other side face 2215, one connecting portion 226 is provided with a guide bend groove 225, and the other connecting portion 226 is provided with a guide bend 223. That is, the two guide bends 223 on each first support rod 220 are located on opposite sides of the first rod body 221, meaning the two guide bends 223 are misaligned and not on the same side of the first rod body 221; the two guide bend grooves 225 on the first support rod 220 are located on opposite sides of the first rod body 221, meaning the two guide bend grooves 225 are misaligned and not on the same side of the first rod body 221. The first arc surface 2230 and the second arc surface 2250 on the same side of the first support rod 220 are coaxial.

[0076] Preferably, such as Figure 15 As shown, the center lines of the first arc surface 2230 and the second arc surface 2250 of each connecting portion 226 are parallel and spaced apart. The plane containing these two center lines is coplanar with the surface of the first rod 221 facing away from the connecting portion 226; that is, the plane containing the center lines of the first arc surface 2230 and the second arc surface 2250 is coplanar with the front surface of the first rod 221. Specifically, the first center line L1 of the first arc surface 2230 and the second center line L2 of the second arc surface 2250 are parallel to each other, and the plane defined by the first center line L1 and the second center line L2 is coplanar with the front surface 2211.

[0077] like Figures 7-14As shown, the first support rod 220 also includes a first stop 224 connected to the guide bend portion 223 and a second stop 227 connected to the connecting portion 226. The second stop 227 is close to the guide bend groove 225. In this embodiment, the first stop 224 of each first support rod 220 is located at the end of the guide bend portion 223 away from the guide bend groove 225, and the second stop 227 of each first support rod 220 is located at the opening end 2251 of the connecting portion 226 near the guide bend groove 225. The first stop 224 and the second stop 227 are located on the side of the connecting portion 226 near the middle of the first rod body 221. Specifically, the first stop portion 224 protrudes from the end 2231 of the guide fold portion 223. The first stop portion 224 extends towards the side near the middle of the first rod body 221. The first stop portion 224 includes a first stop surface 2241 facing the second stop portion 227 and an outer side surface 2243 surrounding the first stop portion 224. The second stop portion 227 is a stop piece provided on the side of the connecting portion 226 near the middle of the first rod body 221. The stop piece extends from the side near the first rod body 221 in the direction of the guide fold groove 225 (i.e., along the Z-axis direction). The second stop portion 227 includes a second stop surface 2271 facing the first stop portion 224 and side surfaces 2273 located on opposite sides of the second stop surface 2271. One side surface 2273 faces the guide fold groove 225, and the other side surface 2273 faces away from the guide fold groove 225. When the two first support rods 220 connected to each other are flattened, the first stop surface 2241 of the first stop portion 224 and the second stop surface 2271 of the second stop portion 227 abut against each other to prevent the two first support rods 220 from bending backward; when the two first support rods 220 are bent, the first stop surface 2241 of the first stop portion 224 and the second stop surface 2271 of the second stop portion 227 move away from each other, so as not to hinder the mutual bending of the two first support rods 220.

[0078] like Figure 5 , Figures 11-14As shown, the first support rod 220 also includes a rolling element 222 movably disposed on the connecting portion 226. When the first support rod 220 moves relative to the guide rail 260, the rolling element 222 rolls into contact with the guide rail 260, causing a rolling connection between the first support rod 220 and the guide rail 260, thereby reducing the frictional resistance between the first support rod 220 and the guide rail 260, which is beneficial for the support device 22 to move around the guide rail 260. The rolling element 222 is located on the side opposite to the front face 2211 of the first rod body 221. The rolling element 222 can be, but is not limited to, a hard ball such as a metal ball. In other embodiments, the rolling element 222 can also be a rolling cylinder, the axis of which is parallel to the axis of the first arc surface 2230. A support portion 228 protrudes from the end of the connecting portion 226 away from the first rod 221. The support portion 228 has a receiving groove 2280, in which the rolling element 222 is placed, with a portion of the outer surface of the rolling element 222 exposed outside the receiving groove 2280. The support portion 228 is connected to the side of the connecting portion 226 away from the first stop portion 224, and a guide space 2282 is formed between the support portion 228 and the first rod 221. The opening of the receiving groove 2280 communicates with the guide space 2282, and the portion of the outer surface of the rolling element 222 exposed outside the receiving groove 2280 is located in the guide space 2282.

[0079] like Figure 13 As shown, in this embodiment, the support portion 228 includes a support block 2281 connected to the connecting portion 226 and a positioning member 2283. A receiving groove 2280 is formed on the surface of the support block 2281 facing the first rod 221. The positioning member 2283 is accommodated in the receiving groove 2280 and is used to prevent the rolling member 222 from disengaging from the receiving groove 2280. Specifically, the support block 2281 extends from the connecting portion 226 to the side away from the first stop portion 224. The receiving groove 2280 extends along the extending direction of the support block 2281, that is, the receiving groove 2280 extends along the Y-axis direction. One end of the receiving groove 2280 away from the connecting portion 226 passes through the end face of the connecting portion 226 to form an inlet. The rolling member 222 is loaded into the receiving groove 2280 through the inlet. In this embodiment, the positioning member 2283 is a soft rubber plug. The positioning member 2283 is inserted into the receiving groove 2280 from the inlet of the support block 2281 to prevent the rolling member 222 from dislodging from the receiving groove 2280. In other embodiments, the positioning member 2283 can also be a hard plug.

[0080] In this embodiment, the first support rod 220 is made of liquid metal through injection molding, that is, the first rod body 221, connecting part 226, first stop part 224, second stop part 227, support part 228, and stop part 2218 are integrally molded; then, the guide bend part 223, the first arc surface 2230, the guide bend groove 225, and the second arc surface 2250 are machined using a CNC machine tool; the processing is simple and the manufacturing cost is low. In other embodiments, the first support rod 220 can also be made of other rigid materials.

[0081] When assembling each first support rod 220 in this embodiment, two rolling elements 222 are respectively inserted into the receiving grooves 2280 through the inlets of the two support blocks 2281, so that each rolling element 222 can roll in the corresponding receiving groove 2280; two positioning elements 2283 are respectively inserted into the receiving grooves 2280 through the inlets of the two support blocks 2281 to prevent the rolling elements 222 from detaching from the corresponding support blocks 2281. In this invention, the assembly of each first support rod 220 does not require tools, making installation simple and convenient.

[0082] Please refer to the following: Figures 16-23When assembling the support device 22, one of the first support rods 220 is placed on one side of the other first support rod 220, so that the first rod bodies 221 of the two first support rods 220 are parallel to each other, and the two first support rods 220 are misaligned in the length direction (i.e., in the Y-axis direction) of the first rod body 221. The guide bend 223 and guide bend groove 225 of one of the first support rods 220 are respectively aligned with the guide bend groove 225 and guide bend 223 of the other first support rod 220 in the length direction (i.e., in the Y-axis direction) of the first rod body 221. One of the first support rods 220 is moved relative to the other first support rod 220 in the length direction (i.e., in the Y-axis direction) of the first rod body 221, so that the guide bend 223 of one of the first support rods 220 is inserted into the guide bend groove 225 of the other first support rod 220. At the same time, the guide bend 223 of the other first support rod 220 is inserted into the guide bend groove 225 of one of the first support rods 220. At this point, the two first support rods 220 are flexibly connected to each other. The guide bend 223 of one first support rod 220 is rotatably accommodated in the guide bend groove 225 of the other first support rod 220. The guide bend 223 of the other first support rod 220 is rotatably accommodated in the guide bend groove 225 of one of the first support rods 220. Each first stop 224 corresponds to a corresponding second stop 227, that is, the first stop surface 2241 of the first stop 224 and the second stop surface 2271 of the corresponding second stop 227 face each other. All the first support rods 220 are assembled into a single unit according to the above assembly method, making the support device 22 a hinge-like whole. The guide bends 223 on opposite sides of each first support rod 220 are respectively accommodated in the guide bend grooves 225 of two adjacent first support rods 220. Each pair of adjacent first support rods 220 is connected by the cooperation of the first arc surface 2230 and the second arc surface 2250, so that the bending or unfolding of the support device 22 is smooth. The support device 22 of the present invention can be assembled by inserting the first support rods 220 into each other without the need for tools, which is convenient and quick to install and has low assembly cost. The first support rods 220 of the support device 22 are assembled together by the cooperation of the guide bending part 223 and the corresponding guide bending groove 225 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 first support rods 220 transmits force to each other, so that the support device 22 can achieve smooth sliding or flattening.

[0083] like Figures 24-33As shown, when two adjacent first support rods 220 are connected to each other, the guide bend 223 of one first support rod 220 is rotatably accommodated in the guide bend groove 225 of the other first support rod 220, and the guide bend groove 225 at the other end of one first support rod 220 receives the guide bend 223 of the other first support rod 220; so that each first arc surface 2230 slides against the corresponding second arc surface 2250. When two adjacent first support rods 220 are flattened, the end 2231 of the guide fold 223 is located at the opening end 2251 of the corresponding guide fold groove 225. The first arc surface 2230 of the guide fold 223 facing the first rod body 221 abuts against the corresponding second arc surface 2250. The adjacent first stop 224 and second stop 227 stop each other, that is, the first stop 224 of one first support rod 220 abuts against the second stop 227 of another first support rod 220 to prevent the two first support rods 220 from bending backwards; when two adjacent first support rods 220 are flattened, the end 2231 of the guide fold 223 is located at the opening end 2251 of the corresponding guide fold groove 225. When a support rod 220 is bent, the end 2231 of the guide bending part 223 can move toward the closed end 2253 of the corresponding guide bending groove 225. The two first arc surfaces 2230 of the guide bending part 223 and the two second arc surfaces 2250 of the corresponding guide bending groove 225 respectively abut against each other. The adjacent first stop parts 224 and second stop parts 227 move away from each other. That is, the first stop part 224 of one first support rod 220 and the second stop part 227 of another first support rod 220 move away from each other, so as not to hinder the mutual bending of the two first support rods 220.

[0084] The two adjacent first support rods 220 can only change between a flattened state and a bent state, such as Figure 22 As shown, when the two first support rods 220 are flattened, the first stop surface 2241 of the first stop portion 224 and the second stop surface 2271 of the second stop portion 227 abut against each other to position the two first support rods 220 in the X-axis direction; the outer surface 2243 of the first stop portion 224 abuts against the corresponding second arc surface 2250 to position the two first support rods 220 in the Z-axis direction; the side surface 2273 of the second stop portion 227 abuts against the guide bend portion 223 to position the two first support rods 220 in the Y-axis direction. Therefore, when the two first support rods 220 are flattened, they can be positioned in the X-axis, Y-axis, and Z-axis directions, maintaining a stable flattened state, improving the flatness of the two first support rods 220, and preventing them from folding back. Figure 32As shown, when the two first support rods 220 bend towards each other, the first stop surface 2241 of the first stop portion 224 and the second stop surface 2271 of the second stop portion 227 separate from each other, so that the two first support rods 220 are released in the X-axis direction; the outer side surface 2243 of the first stop portion 224 abuts against the corresponding second arc surface 2250, so that the two first support rods 220 are positioned against each other in the Z-axis direction; one side surface 2273 of the second stop portion 227 abuts against the guide bending portion 223, so that the two first support rods 220 are positioned against each other in the Y-axis direction; therefore, when the two first support rods 220 are in the bent state, the two first support rods 220 can be bent or flattened along the guide bending groove 225.

[0085] Please refer to the following: Figures 1-5When assembling the electronic device 100, two guide rails 271 are placed parallel and spaced apart within the first receiving space 247 of the first housing 24 and positioned on the first bottom wall 243; two guide sliders 273 are placed spaced apart within the second receiving space 2627 of the second housing 26 and positioned on the second bottom wall 2623; two sliders 2628 of the second housing 26 are slidably inserted into the two guide grooves 2415 of the first housing 24, and the two guide sliders 273 on the second housing 26 are slidably connected to the two guide rails 271, and multiple guide rods 2624 are slidably inserted into multiple guide grooves 2411; the back of the sliding area 54 of the flexible screen 50 is connected to the support device 22 through an adhesive layer, specifically... Adhesive is applied to the front of the first support rod 220 and the adhesive groove 2217. The back of the sliding area 54 is then attached to the front of the first support rod 220, so that the flexible screen 50 is bonded to the support device 22. At this time, the rotation axis between two adjacent first 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 2410 of the first housing 24, and the back of the positioning area 52 is fixedly attached to the front of the first top wall 241. The positioning strip 521 is engaged in the connecting groove 2413 of the first housing 24. The side of the support device 22 away from the flexible screen 50 surrounds the second housing 26, that is, the support device 22 and the sliding area 54 surround the second housing 26 together. The second top wall 2621, second side wall 2625, and second bottom wall 2623 of the 6; the first support rod 220 of the support device 22 near the positioning area 52 is connected to the first housing 24, and the first support rod 220 of the support device 22 away from the positioning area 52 is connected to the guide rail 260 through the end connector 229. The end connector 229 includes a connecting plate 2291, a support piece 2293 at the end of the connecting plate 2291, and a guide column 2295 at the support piece 2293. A guide space is formed between the guide column 2295 and the connecting plate 2291, and at least part of the guide rail 260 is slidably accommodated in the guide space. The guide column 2295 slidably contacts the guide rail 260; the two shielding members 265 are respectively connected to the second housing 24. Specifically, for the two second end walls 2626 of the 6, multiple fasteners such as screws pass through the through holes 2655 and are locked into the corresponding connecting holes, and the snap-fit ​​block 2656 of each shield 265 snaps into the corresponding snap-fit ​​hole of the second end wall 2626; at this time, the support device 220 is arranged around the second housing 26, and at least part of the guide rail 260 is slidably accommodated in the guide space 2282 of the support device 220, and the rolling element 222 is in rolling contact with the guide rail 260; specifically, the guide rails 260 of the two shields 265 are respectively accommodated in the guide spaces 2282 at opposite ends of the support device 22, the rolling element 222 is in rolling contact with the corresponding guide rail 260, and the curved guide rail 2603 is coaxial with the outer surface of the second side wall 2625;The end cap 267's cover plate 2671 covers the sliding roll area 54 on the side of the second housing 26 away from the first housing 24, and two connecting plates 2673 respectively cover the ends of the two shielding members 265 away from the first housing 24, so that the positioning holes 2676 on each connecting plate 2673 correspond to the corresponding through holes 2655 and connecting holes. Two fasteners, such as screws, pass through the two positioning holes 2676 and through holes 2655 respectively and are locked into the corresponding connecting holes, so that the cover plate 267 is fixedly connected to the second housing 26. The flexible screen support device 22 and the flexible screen 50 surrounding the second side wall 2625 are slidably accommodated in the receiving space 2674.

[0086] At this time, the connecting portion 226 and the guide portion 223 of the support device 22 are located on the back side of the first support rod 220 near the end face, rather than being directly disposed on the end face of the first support rod 220. Therefore, the connecting portion 226 and the guide portion 223 avoid occupying the space on opposite sides of the housing 20. In addition, the shielding member 265 shields the guide portion 223, the guide groove 225, and the connecting portion 226 of the first support rod 220, which not only prevents external dust and debris from entering the interior of the housing 20, but also prevents the guide portion 223, the guide groove 225, and the connecting portion 226 from being exposed, thus improving the overall performance of the electronic device 100. In terms of appearance and performance, the rotation axis between any two adjacent first support rods 220 is located on the adhesive layer of the first support rod 220. That is, the axis of the first arc surface 2230 and the axis of the second arc surface 2250 are both located on the connecting adhesive layer between the first support rod 220 and the flexible screen 50. This ensures that the flexible screen support device 22 is not squeezed or stretched during bending or flattening, thereby effectively protecting the connecting adhesive layer from damage and preventing the flexible screen 50 from detaching from the first support rod 220. This ensures a stable and secure connection between the flexible screen 50 and the flexible screen support device 22.

[0087] like Figures 1-6 and Figures 34-38As 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 a user's pulling force), causing the first housing 24 and the second housing 26 to slide away from each other. The guide rod 2624 slides along the corresponding guide groove 2411 away from the first housing 24, the slider 2628 slides along the corresponding guide groove 2415 away from the first housing 24, and the guide slider 273 slides on the corresponding guide rail 271 away from the first housing 24; the sliding frame 262... The support device 22 slides to unfold, allowing it to slide around the second housing 26. Specifically, the first support rod 220, which is attached to the second bottom wall 2623, is first bent and then flattened on the outer side of the second side wall 2625 and slides to the front of the second top wall 2621. The first support rod 220 of the support device 22 slides away from the first housing 24 until the end connector 229 slides to the top of the bending guide rail 2603, and the sliding roll area 54 is fully unfolded with the support device 22.

[0088] Please refer to the following: Figures 39-46 The flexible screen 50 of the electronic device 100 is rolled up as follows: An external force (such as a user's push) pushes the first housing 24 and / or the second housing 26, causing the first housing 24 and the second housing 26 to slide relative to each other and retract. The guide rod 2624 slides along the corresponding guide groove 2411 and approaches the first housing 24. The slider 2628 slides along the corresponding guide groove 2415 and approaches the first housing 24. The guide slider 273 slides on the corresponding guide rail 271 and approaches the first housing 24. The sliding frame 262... The sliding relative to the support device 22 causes the support device 22 to curl, allowing the support device 22 to slide around the second housing 26. Specifically, the first support rod 220, which is attached to the second top wall 2621, first bends and then flattens and slides to the back of the second bottom wall 2623 via the outer side of the second side wall 2625. The first support rod 220 of the support device 22, which is away from the first housing 24, slides towards the first housing 24 until the end connector 229 slides to abut against the first housing 24, and 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, the force is transmitted between each pair of adjacent first support rods 220 through the cooperation of the guide fold 223 and the guide fold groove 225, thereby reducing the stress on the flexible screen 50, protecting the flexible screen 50, improving the reliability of the flexible screen 50, and preventing creases from appearing after multiple rolls, thus not affecting the appearance and improving the user experience; the rolling element 222 makes rolling contact with the corresponding guide rail 260, so that the frictional resistance of the support device 22 relative to the guide rail 260 is small, which facilitates the unfolding of the support device 22 and the flexible screen 50; since the outer surface of the second side wall 2625 is an arc surface, and the outer surface of the second side wall 2625 is coaxial with the curved guide rail 2603, it facilitates the unfolding of the support device 22 and the flexible screen 50. 2. The first support rod 220 is bent along the outer surface of the second side wall 2625. The first arc surface 2230 and the corresponding second arc surface 2250 slide against each other through the cooperation of the guide bending part 223 and the guide bending groove 225, so that the bending and unfolding of the support device 22 is smooth. After the first support rod 220 passes the outer surface of the second side wall 2625 and unfolds, the first stop part 224 and the second stop part 227 abut against each other for positioning, which can prevent the two first support rods 220 from bending in the opposite direction, so as to ensure that the two first support rods 220 have stable flatness to provide stable support for the flexible screen 50, and can prevent the first support rods 220 from bending in the opposite direction and arching the flexible screen 50, effectively protecting the flexible screen 50.
