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 that enables the flexible screen to experience less stress 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 first support rods rotatably connected to each other along a first direction. Each first support rod includes a first rod body, a first guide bend, and a second guide bend. The first rod body includes two opposing sides along the first direction. Each side of the first rod body is provided with the first guide bend and the second guide bend. The first guide bend and the second guide bend on one side of one first support rod are rotatably abutted against the second guide bend and the first guide bend on one side of an adjacent first support rod, respectively.

[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 of 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 first guide bend and a corresponding second guide bend. During the rotation of the two adjacent first support rods relative to each other, the first guide bend slides against the second guide bend, so that there is a force transmitted 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, and it does not affect the appearance, thus improving 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

[0056] 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 electronic device 100 also includes a motherboard and a 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.

Specifically, multiple 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 side wall 245. The multiple guide grooves 2411 are arranged along the Y-axis, and each guide groove 2411 extends along the X-axis. A connecting groove 2413 is provided on the first side wall 245 near the first top wall 241. The connecting groove 2413 connects to the positioning groove 2410. The two opposite 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. Guide grooves 2415 are provided on opposite ends of the first housing 24. The guide grooves 2415 extend along the X-axis to near the first side wall 245, and the second housing 26 is slidably connected to the guide grooves 2415. Specifically, guide grooves 2415 are provided between the opposite ends of the first top wall 241 and the two first end walls 246. Preferably, the outer surface of the first side wall 245 is an arc surface.

[0059] 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.

[0060] 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 extending 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, and 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, multiple clearance grooves 2622 are located on the second top wall 2621, and are arranged along the Y-axis. Each clearance groove 2622 passes through the second top wall 2621, with one end extending close to the second side wall 2625. The opposite end of the clearance groove 2622 passes through 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 Y-axis, and correspond one-to-one with the multiple guide grooves 2411 of the first housing 24. The outer surface of the second side wall 2625 is an arc surface, that is, the outer surface of the second side wall 2625 away from the first housing 24 is an arc surface, 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 slidably inserted into the guide groove 2415 corresponding to 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 X-axis and has a plurality of spaced-apart connecting holes and snap-fit ​​holes. The plurality of connecting holes are spaced apart along the X-axis, and one connecting hole is 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.

[0061] 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 the 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 have a smooth transition. The support device 22 is slidably wound around the guide rail 260. The blocking member 265 has a plurality of through holes 2655 spaced apart and a snap-fit ​​block 2656 in the middle.

[0062] 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.

[0063] The first housing 24 and the second housing 26 are slidably connected by guide rails 271 and guide sliders 273. The guide rails 271 are located in one of the first housing 24 and the second housing 26, and the guide sliders 273 are located in the other. In this embodiment, the first housing 24 has two parallel and spaced-apart guide rails 271 in its first receiving space 247, extending along the X-axis. The second housing 26 has two spaced-apart guide sliders 273 in its second receiving space 2627. 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. 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.

[0064] In some embodiments, the second housing 26 has a guide rail 271 in its second receiving space 2627, which extends along the X-axis. The first housing 24 has a guide slider 273 in its first receiving space 274. 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 has two parallel and spaced guide rails 271 on its surface facing the second receiving space 2627, and the first bottom wall 243 of the first housing 24 has two spaced guide sliders 273 on its surface facing the first receiving space 274. 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.

[0065] like Figures 5-8 As shown, the support device 22 includes a plurality of first support rods 220 rotatably connected to each other along a first direction (i.e., the X-axis direction), and adjacent first support rods 220 can be flattened or bent relative to each other; each first support rod 220 includes a first rod body 221, a first guide bend 223, and a second guide bend 225. The first rod body 221 includes opposite sides along the first direction (i.e., the X-axis direction), and each side of the first rod body 221 is provided with a first guide bend 223 and a second guide bend 225, wherein one first support rod 220... The first guide bend 223 and the second guide bend 225 on one side are rotatably abutted against the second guide bend 225 and the first guide bend 223 on the side of the adjacent first support rod 220, respectively; that is, the first guide bend 223 on one side of the first support rod 220 and the second guide bend 225 on the side of the other first support rod 220 are rotatably abutted against each other, and the second guide bend 225 on one side of the first support rod 220 and the first guide bend 223 on the side of the other first support rod 220 are rotatably abutted against each other. When two adjacent first support rods 220 rotate relative to each other, the first guide bend 223 and the corresponding second guide bend 225 of the two adjacent first support rods 220 rotate relative to each other, so that the two adjacent first support rods 220 can transmit force to each other, so that the support device 22 can bend or flatten. 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 near the first housing 24 is connected to the first housing 24.

[0066] 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 two adjacent first support rods 220 in the support device 22 are rotatably connected by the cooperation of the first guide bend 223 and the second guide bend 225, during the rotation of the two adjacent first support rods 220 relative to each other, the first guide bend 223 slides against the second guide bend 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.

[0067] 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. Each side of the first rod 221 is provided with a first guide bend 223 and a second guide bend 225. Preferably, the opposite sides of the front face 2211 are arc-shaped surfaces. In other embodiments, the front face 2211 may be provided with multiple 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 first support rod 220. Along the length direction of the first rod 221, there are respectively provided at opposite ends of the front face 2211 of the first rod 221. The space between the two ends of ... The side wall of the first rod 221 is provided with a clearance opening 2210 corresponding to the first guide bend 223. The clearance opening 2210 is used to accommodate the corresponding second guide bend 225.

[0068] The first guide bend 223 includes a first arc surface 2230, and the second guide bend 225 includes a second arc surface 2250. The first arc surface 2230 and the second arc surface 2250 on the same side of the first support rod 220 are coaxial. The first arc surface 2230 and the second arc surface 2250 on one side of the first support rod 220 are respectively rotatably abutting against the second arc surface 2250 and the first arc surface 2230 on the side of the adjacent first support rod 220, and the abutting first arc surface 2230 and the second arc surface 2250 are coaxial. When the first guide bend 223 of one of the first support rods 220 abuts against the second guide bend 225 of the adjacent first support rod 220, the first guide bend 223 overlaps with the corresponding second guide bend 225. The first arc surface 2230 and the second arc surface 2250 on one side of one of the first support rods 220 abut against the second arc surface 2250 and the first arc surface 2230 on the other side of the first support rod 220, respectively, in a rotational abutment relative to each other. At this time, the first arc surface 2230 and the second arc surface 2250 are coaxial, and there is a mutual abutting force between the first arc surface 2230 and the second arc surface 2250, so that the two adjacent first support rods 220 can be flattened or bent relative to each other.

[0069] The first support rod 220 has a first guide bend 223 and a second guide bend 225 on opposite sides. The first guide bend 223 and the second guide bend 225 on the same side of the first support rod 220 are spaced apart from each other along the length direction of the first rod body 221. The first guide bend 223 on one side of the first support rod 220 and the second guide bend 225 on the opposite side are directly opposite each other along a first direction (i.e., the X-axis direction), wherein the length direction of the first rod body 221 is perpendicular to the first direction. Specifically, the first support rod 220 has at least one first guide bend 223 and at least one second guide bend 225 on opposite sides. The first guide bend 223 and the second guide bend 225 on the same side of the first support rod 220 are spaced apart from each other. The two first guide bends 223 on opposite sides of the first support rod 220 are staggered in the Y-axis direction, and the two second guide bends 225 on opposite sides of the first support rod 220 are staggered in the Y-axis direction. A first guide bend 223 and a second guide bend 225 on the same side of the first support rod 220 form a connecting unit. At least one connecting unit is provided on each of the opposite sides of the first support rod 220. Two adjacent first support rods 220 are rotatably connected by the cooperation of at least one pair of the connecting units. That is, the first guide bend 223 of the connecting unit on one side of one first support rod 220 and the second guide bend 225 of the connecting unit on the other side of the first support rod 220 rotatably abut against each other. The second guide bend 225 of the connecting unit on one side of one first support rod 220 and the first guide bend 223 of the connecting unit on the other side of the first support rod 220 rotatably abut against each other.

[0070] The first guide bend 223 includes a first arc strip on the back surface 2213 of the first rod 221, and the second guide bend 225 includes a second arc strip on the back surface 2213 of the first rod 221. The first arc surface 2230 is provided on the surface of the first arc strip facing the first rod 221, and the second arc surface 2250 is provided on the surface of the second arc strip away from the first rod 221. When the first arc surface 2230 and the corresponding second arc surface 2250 of two adjacent first support rods 220 rotate and abut against each other, the second guide bend 225 is closer to the first rod 221 than the first guide bend 223. The first and second arc strips on the same side of the first rod 221 extend toward the same side of the first rod 221. Specifically, the first guide bend 223 bends and extends from one side 2215 near the first rod 221 to away from the other side 2215 and away from the back face 2213, and the first arc surface 2230 is provided on the side of the first arc strip facing the back face 2213; the second guide bend 225 bends and extends from one side 2215 near the first rod 221 to away from the other side 2215 and away from the back face, and the second arc surface 2250 is provided on the side of the second arc strip away from the back face 2213; preferably, the first arc surface 2230 and the second arc surface 2250 on the same side of the first rod 221 share the same arc surface. Specifically, the first guide bend 223 includes a first end 2231 and a first connecting end 2233 located at opposite ends thereon. The first connecting end 2233 is used to connect to the first rod 221, and the first end 2231 is farther away from the first rod 221 than the first connecting end 2233. The second guide bend 225 includes a second end 2251 and a second connecting end 2253 located at opposite ends thereon. The second connecting end 2253 is used to connect to the first rod 221, and the second end 2251 is farther away from the first rod 221 than the second connecting end 2253. In this embodiment, the first guide bend 223 has arc surfaces on both its surface facing the first rod 221 and its surface away from the first rod 221. These two arc surfaces are parallel, and the arc surface facing the first rod 221 is the first arc surface 2230. Similarly, the second guide bend 225 has arc surfaces on both its surface away from the first rod 221 and its surface facing the first rod 221, and the surface of the second guide bend 225 away from the first rod 221 is the second arc surface 2250. In other embodiments, the surface of the first guide bend 223 away from the first rod 221 may not be an arc surface, and the surface of the second guide bend 225 facing the first rod 221 may not be an arc surface.

[0071] Please refer to the following: Figures 7-14The first support rod 220 further includes a first stop 224 connected to the first guide bend 223 and a second stop 227 connected to the second guide bend 225. Both the first stop 224 and the second stop 227 are located away from the first rod body 221. Preferably, the first stop 224 is located at the end of the first guide bend 223 away from the first rod body 221, and the second stop 227 is located at the end of the second guide bend 225 away from the first rod body 221. The first stop 224 on one side of the first rod body 221 and the second stop 227 on the opposite side are directly opposite each other along the first direction (i.e., the X-axis direction), that is, the first stop 224 and the second stop 227 are directly opposite each other in the X-axis direction. Specifically, the first stop portion 224 is a protrusion provided at the first end 2231 of the first guide bend portion 223. The first stop portion 224 extends from the first guide bend portion 223 along the axis of the first arc surface 2230 (i.e., along the Y-axis direction) toward the second guide bend portion 225 on the same side as the first rod body 221. The second stop portion 227 is a protrusion provided at the second end 2251 of the second guide bend portion 225. The second stop portion 227 protrudes from the second arc surface 2250 of the second guide bend portion 225 near the end of the first guide bend portion 223 on the same side as the first rod body 221. The first stop portion 224 on one side of the first rod 221 includes a first stop surface 2241 facing the second stop portion 227 on the opposite side of the first rod 221, and a second stop surface 2243 facing the first rod 221; 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 221, the stop piece extending from the side near the first rod 221 toward the adjacent second guide portion 225 (i.e., along the Z-axis direction); the second stop portion 227 on one side of the first rod 221 includes a third stop surface 2271 facing the first stop portion 224 on the opposite side of the first rod 221, and a fourth stop surface 2273 facing the first stop portion 224 along the length direction of the first rod 221, i.e., the fourth stop surface 2273 on the second stop portion 227 is opposite to the first stop portion 224 of the adjacent first stop portion 224. When the two first support rods 220 connected to each other are flattened, the first stop surface 2241 of one first support rod 220 abuts against the third stop surface 2271 of the other first support rod 220 to prevent the two first support rods 220 from bending backwards; when the two first support rods 220 are bent, the first stop surface 2241 of one first support rod 220 and the third stop surface 2271 of the other first support rod 220 move away from each other, so as not to hinder the mutual bending of the two first support rods 220.

[0072] In other embodiments, the first stop portion on the first guide bend portion 223 on the same side of the first support rod 220 and the second stop portion on the second guide bend portion 225 can be interchanged, that is, the first guide bend portion 223 on each side of the first support rod 220 is provided with a second stop portion, and the second guide bend portion 225 is provided with a first stop portion.

[0073] In other embodiments, the positions of the first guide bend 223 and the second guide bend 225 on the same side of the first support rod 220 can be interchanged, that is, the positions of the first guide bend 223 and the second guide bend 225 on one side of the first support rod 220 are interchanged, and the positions of the second guide bend 223 and the second guide bend 225 on the opposite side of the first support rod 220 are interchanged.

[0074] like Figures 7-10 As shown, in this embodiment, each first support rod 220 has two mutually spaced first guide bends 223 and two mutually spaced second guide bends 225 on opposite sides. The two first guide bends 223 and two second guide bends 225 on one side of the first support rod 220 are respectively arranged along the length direction of the first rod body 221 near the opposite ends of the first support rod 220. The two first guide bends 223 and two second guide bends 225 on the other side of the first support rod 220 are respectively arranged along the length direction of the first rod body 221 near the opposite ends of the first support rod 220. The two first guide bends 220 and two second guide bends 225 at the same end of the first support rod 220 are directly opposite each other along the first direction (i.e., the X-axis direction). The center lines of the two first arc surfaces 2230 on the same side of the first support rod 220 are collinear with the center lines of the two second arc surfaces 2250. Specifically, on one side of the first rod 221, two first guide bends 223 and two second guide bends 225 are located near opposite ends of the first rod 221, with the two second guide bends 225 positioned between the two first guide bends 223; on the other side of the first rod 221, two first guide bends 223 and two second guide bends 225 are located near opposite ends of the first rod 221, with the two first guide bends 223 positioned between the two second guide bends 225. The two first guide bends 223 on one side of the first rod 221 are offset from the two first guide bends 223 on the other side, and the two second guide bends 225 on one side of the first rod 221 are also offset from the two second guide bends 225 on the other side. The two first guide bends 223 on one side of the first rod 221 correspond one-to-one with the two second guide bends 225 on the other side, and the two second guide bends 225 on one side of the first rod 221 correspond one-to-one with the two first guide bends 223 on the other side.

[0075] In some embodiments, the first support rod 220 is provided with a first guide bend 223 and a second guide bend 225 spaced apart from each other on opposite sides. The first guide bend 223 and the second guide bend 225 on one side of the first support rod 220 are located near the middle of the first support rod 220, and the first guide bend 223 and the second guide bend 225 on the other side of the first support rod 220 are located near the middle of the first support rod 220. The first guide bend 223 on one side of the first support rod 220 and the second guide bend 225 on the other side are directly opposite each other along the first direction (i.e., the X-axis direction). The second guide bend 225 on one side of the first support rod 220 and the first guide bend 223 on the other side are directly opposite each other along the first direction (i.e., the X-axis direction).

[0076] In some embodiments, the first support rod 220 has three or more first guide bends 223 and three or more second guide bends 225 spaced apart on opposite sides. The number of first guide bends 223 on one side of the first support rod 220 is the same as the number of second guide bends 225 on the other side. Each of the three or more first guide bends 223 on one side of the first support rod 220 corresponds one-to-one with each of the three or more second guide bends 225 on the other side, and vice versa.

[0077] Preferably, such as Figure 15 As shown, the plane containing the centerlines of the two first arc surfaces 2230 on opposite sides of the first support rod 220 is coplanar with the front surface of the first rod body 221, or the plane containing the centerlines of the two second arc surfaces 2250 on opposite sides of the first support rod 220 is coplanar with the front surface of the first rod body 221. Specifically, the centerlines of the first arc surfaces 2230 on the same side of the first support rod 220 are collinear with the centerlines of the second arc surfaces 2250, the centerlines of the two first arc surfaces 2230 on opposite sides of the first support rod 220 are parallel and spaced apart, and the plane containing the two centerlines is coplanar with the front surface 2211 of the first rod body 221. The plane containing the centerlines of the first arc surfaces 2230 and the second arc surfaces 2250 is coplanar with the front surface 2211 of the first rod body 221. Specifically, the first axis line L1 of the first arc surface 2230 on one side of the first support rod 220 is parallel to the second axis line L2 of the second arc surface 2250 on the other side, and the plane determined by the first axis line L1 and the second axis line L2 is coplanar with the front face 2211.

[0078] like Figure 5 and Figures 11-15As shown, the first support rod 220 also includes a connecting portion 226 connected to the back side 2213 of the first rod body 221, and a support portion 228 connected to the end of the connecting portion 226 away from the first guide bend portion 223. The connecting portion 226 is located near the end of the first rod body 221. The support portion 228, the connecting portion 226 and the first rod body 221 form a guide space 2282, which is used to accommodate the guide rail 260. Specifically, the connecting portion 226 extends along the Z-axis direction from the back surface 2213 of the first rod 221 near the end face 2216, and the width of the connecting portion 226 on the X-axis gradually decreases along the extension direction of the connecting portion 226, so that the width of the end of the connecting portion 226 connected to the first rod 221 extending along the X-axis direction is greater than the width of the end of the connecting portion 226 away from the first rod 221 extending along the X-axis direction; the supporting portion 228 extends from the end of the connecting portion 226 away from the first rod 221 along the Y-axis direction to the end away from the first guide bend 223; preferably, the supporting portion 228 is a circular cylinder. In this embodiment, the back surface 2213 of the first rod 221 is provided with connecting portions 226 at opposite ends. Each connecting portion 226 has a support portion 228 on the side away from the first rod 221 and opposite to the first guide bend portion 223. Each support portion 228, the connecting portion 226, and the first rod 221 form a guide sliding space 2282, that is, a guide sliding space 2282 is formed at opposite ends of the first rod 221. Preferably, the end face of the connecting portion 226 away from the first rod 221 is an arc surface, and the support portion 228 is a circular cylinder, the outer circumferential surface of which is coplanar with the arc surface.

[0079] The first support rod 220 also includes a rolling element 222, which is movably disposed on the support portion 228 or 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, thereby reducing the frictional resistance between the first support rod 220 and the guide rail 260 and facilitating the movement of the support device 22 around the guide rail 260. In this embodiment, the rolling element 222 is disposed on the side of the support portion 228 facing 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. Specifically, the support portion 228 is located away from the first guide bend portion 223. The support portion 228 has a receiving groove 2280, the opening of which connects to the guide sliding space 2282. The rolling element 222 is rotatably placed in the receiving groove 2280, with a portion of its outer surface 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. The opening of the receiving groove 2280 connects to the guide sliding space 2282, and the portion of the outer surface of the rolling element 222 exposed outside the receiving groove 2280 is located within the guide sliding space 2282.

[0080] like Figure 11 and Figure 13 As shown, in this embodiment, the first support rod 220 further includes a positioning member 2283. A receiving groove 2280 is formed on the surface of the support portion 228 facing the first rod body 221. The positioning member 2283 is housed in the receiving groove 2280 and is used to prevent the rolling member 222 from dislodging from the receiving groove 2280. Specifically, the receiving groove 2280 extends away from the connecting portion 226 along the extending direction of the support portion 228 (i.e., along the Y-axis direction). The 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 inserted into the receiving groove 2280 through the inlet. In this embodiment, the positioning member 2283 is a soft rubber plug. The inlet of the positioning member 2283 supporting portion 228 is inserted into the receiving groove 2280 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.

[0081] In this embodiment, the first support rod 220 is made of liquid metal through injection molding. Specifically, the first rod body 221, the first guide bend 223, the first stop 224, the second guide bend 225, the second stop 227, the connecting part 226, the support part 228, and the stop 2218 are integrally molded. Therefore, the first support rod 220 is easy to process and has low manufacturing cost. In other embodiments, the first support rod 220 can also be made of other rigid materials.

[0082] 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 portions 228, 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 portions 228 to prevent the rolling elements 222 from disengaging from their corresponding positions. In this invention, the assembly of each first support rod 220 does not require tools, making installation simple and convenient.

[0083] Please refer to the following: Figures 16-26When 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 first rod bodies 221 of the two first support rods 220 are misaligned in the Y-axis direction, so that the first guide bend 223 and the second guide bend 225 of one of the first support rods 220 are misaligned in the Y-axis direction with the second guide bend 225 and the first guide bend 223 of the other first support rod 220, and the first guide bend 225 of one of the first support rods 220 is misaligned with the second guide bend 225 and the first guide bend 223 of the other first support rod 220. One guide bend 223 and the second guide bend 225 of another first support rod 220 are directly opposite each other along the first direction (i.e., the X-axis direction), and the first stop 224 and the corresponding second stop 227 are offset from each other in the X-axis direction; one of the first support rods 220 is moved relative to the other first support rod 220 along the Y-axis direction, so that the first guide bend 223 of one of the first support rods 220 covers the corresponding second guide bend 225, so that each first arc surface 2230 and the corresponding second arc surface 2250 are rotatably fitted together. At this time, the two first support rods 220 are flexibly connected to each other, wherein the first guide bend 223 of one first support rod 220 is rotatably connected to the second guide bend 225 of the other first support rod 220, and the first guide bend 223 of the other first support rod 220 is rotatably connected to the second guide bend 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 third stop surface 2271 of the corresponding second stop 227 are directly opposite each other along the first direction (i.e., the X-axis direction). All the first support rods 220 are assembled into one unit according to the above assembly method, so that the support device 22 is a hinge-like whole, and the first guide bends 223 on opposite sides of each first support rod 220 are rotatably connected to the second guide bends 225 of the two adjacent first support rods 220. Each pair of adjacent first support rods 220 is connected by the cooperation of a first arc surface 2230 and a second arc surface 2250, making the bending or unfolding of the support device 22 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, making installation convenient and quick, and reducing assembly costs. The first support rods 220 of the support device 22 are assembled together by the cooperation of a first guide bend 223 and the corresponding second guide bend 225 of the adjacent first 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 first support rods 220 transmits force to each other, enabling the support device 22 to achieve smooth sliding or flattening.

[0084] like Figures 27-30As shown, when two adjacent first support rods 220 are connected to each other, the first guide bend 223 of one first support rod 220 is rotatably connected to the second guide bend 225 of the other first support rod 220, and the first guide bend 223 of the other first support rod 220 is rotatably connected to the second guide bend 225 of one of the first support rods 220; so that each first arc surface 2230 and the corresponding second arc surface 2250 slide against each other. When two adjacent first support rods 220 are flattened, their front faces 2211 are coplanar, and the first end 2231 of the first guide bend 223 of each first support rod 220 is away from the back face 2213 of the adjacent first support rod 220; the first arc surface 2230 of each first guide bend 223 abuts against the second arc surface 2250 of the corresponding second guide bend 225, and the adjacent first stop 224 and second stop 227 stop against each other, that is, the first stop 224 of one first support rod 220 abuts against the second stop 227 of the other first support rod 220 to prevent the two first support rods 220 from folding back; when two adjacent first support rods 220 are flattened, their front faces 2211 are coplanar, and the first end 2231 of the first guide bend 223 of each first support rod 220 is away from the back face 2213 of the adjacent first support rod 220; when two adjacent first support rods 220 are flattened, their front faces 2211 are coplanar, and the first end 2231 of the first guide bend 223 of each first guide bend 225 abuts against each other, and the adjacent first stop 224 and second stop 227 stop against each other, that is, the first stop 224 of one first support rod 220 abuts against the second stop 227 of the other first support rod 220 to prevent the two first support rods 220 from folding back; when two adjacent first support rods 220 are flattened, their front faces 2211 are coplanar, and the first end 2231 of the first guide bend 223 of each first support rod 220 is coplanar, and the first end 2231 of the first guide bend 223 of each first guide be When a support rod 220 bends, the front faces 2211 of the two first support rods 220 bend towards each other, the first arc surface 2230 of each first guide bend portion 223 abuts against the second arc surface 2250 of the corresponding second guide bend portion 225, the first end 2231 of the first guide bend portion 223 of each first support rod 220 approaches or abuts against the back face 2213 of the adjacent first support rod 220, and the adjacent first stop portion 224 and second stop portion 227 move away from each other, that is, the first stop portion 224 of one first support rod 220 and the second stop portion 227 of the other first support rod 220 move away from each other, so as not to hinder the mutual bending of the two first support rods 220.

[0085] The two adjacent first support rods 220 can only change between a flattened state and a bent state, such as Figure 20As shown, when the two first support rods 220 are flattened, the first stop surface 2241 of the first stop portion 224 of one first support rod 220 abuts against the third stop surface 2271 of the second stop portion 227 of the other first support rod 220, so that the two first support rods 220 are positioned relative to each other in the X-axis direction; the second stop surface 2243 of the first stop portion 224 of one first support rod 220 abuts against the corresponding second arc surface 2250 of the other first support rod 220, so that the two first support rods 220 are positioned relative to each other in the Z-axis direction; the fourth stop surface 2273 of the second stop portion 227 of the other first support rod 220 abuts against the first guide bend portion 223 of one of the first support rods 220, so that the two first support rods 220 are positioned relative to each other in the Y-axis direction. Therefore, when the two first support rods 220 are in the flattened state, they can be positioned in the X-axis, Y-axis, and Z-axis directions, maintaining a stable flattened state, improving their flatness, and preventing them from folding back. Figure 30 As shown, when the two first support rods 220 bend towards each other, the first stop surface 2241 of the first stop portion 224 of one first support rod 220 separates from the third stop surface 2271 of the second stop portion 227 of the other first support rod 220, thereby releasing the two first support rods 220 in the X-axis direction; the second stop surface 2243 of the first stop portion 224 of one first support rod 220 abuts against the corresponding second arc surface 2250 of the other first support rod 220. The top is used to position the two first support rods 220 relative to each other in the Z-axis direction; the fourth stop surface 2273 of the second stop portion 227 of the other first support rod 220 abuts against the first guide bend portion 223 of one of the first support rods 220 to position the two first support rods 220 relative to 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 cooperation of the first arc surface 2230 and the second arc surface 2250.

[0086] 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 slots 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 slots 2411; 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 first support rod 220, and then the back side of the sliding roll area 54 is attached to the front side 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 accommodated in the positioning groove 2410 of the first housing 24, and the back side of the positioning area 52 is fixedly attached to the front side of the first top wall 241. The positioning strip 521 is snapped into the connecting groove 2413 of the first housing 24. The side of the support device 22 away from the flexible screen 50 is surrounded around the second housing 26, that is, the support device 22 and the sliding roll area 54 are together surrounded around the second top wall of the second housing 26. 2621, second sidewall 2625, and second bottom wall 2623; 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 an 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 post 2295 at the support piece 2293. A guide space 2282 is formed between the guide post 2295 and the connecting plate 2291. The guide rail 260 is slidably accommodated in the guide space 2282, and the guide post 2295 slidably contacts the guide rail 260; the two blocking members 265 are respectively connected to the second housing 26. Specifically, multiple fasteners such as screws pass through the through holes 2655 and are locked into the corresponding connection holes of the two second end walls 2626, 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 22 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 22, 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 the 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 2671 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.

[0087] At this time, the connecting portion 226, the supporting portion 228, the first guide bend 223, and the second guide bend 225 of the support device 22 are all located on the back side of the first support rod 220 near the end face, rather than directly on the end face of the first support rod 220. Therefore, the connecting portion 226, the supporting portion 228, the first guide bend 223, and the second guide bend 225 avoid occupying the space on opposite sides of the housing 20. In addition, the shielding member 265 shields the connecting portion 226, the supporting portion 228, the first guide bend 223, and the second guide bend 225 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 connecting portion 226, the supporting portion 228, the first guide bend 223, and the second guide bend 225 from occupying the space on opposite sides of the housing 20. The fold 223 and the second guide fold 225 are not exposed, improving the overall appearance of the electronic device 100. Furthermore, 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 prevents the flexible screen support device 22 from being squeezed or stretched during bending or flattening, effectively protecting the connecting adhesive layer from damage and preventing the flexible screen 50 from detaching from the first support rod 220, thus ensuring a stable and secure connection between the flexible screen 50 and the flexible screen support device 22.

[0088] like Figures 1-6 and Figures 31-33As 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.

[0089] Please refer to the following as well: Figures 1-6 and Figures 34-40 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.

[0090] During the unfolding or rolling process of the flexible screen 50, the force between each pair of adjacent first support rods 220 is transferred through the cooperation of the first guide fold 223 and the second guide fold 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 first guide bend 223 and the second guide bend 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 224 and the second stop 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.

The outermost first support rod 220 refers to one of the two outermost first support rods 220 opposite to each other among the plurality of first support rods 220. The second support rod 220a and the first support rod 220 are rotatably connected by the cooperation of the first guide bend 223 and the second guide bend 225. The structure of the second support rod 220a is similar to that of the first support rod 220. The difference is that the second support rod 220a omits the first guide bend 223 and the second guide bend 225 on one side of the first support rod 220. Specifically, the second support rod 220a has the first guide bend 223 and the second guide bend 225 on the side facing the first support rod 220, and the side of the second support rod 220a away from the first support rod 220 does not have the first guide bend 223 and the second guide bend 225, so as to facilitate the connection of the second support rod 220a to the housing of the electronic device.

That is, the second support rod 220a and the third support rod 220b are respectively connected to the two outermost first support rods 220 on opposite sides of the plurality of first support rods 220, i.e., the third support rod 220a... 20b is connected to the first support rod 220 on the side of the plurality of first support rods 220 away from the second support rod 220a.

The third support rod 220b and the corresponding first support rod 220 are rotatably connected through the cooperation of the first guide bend 223 and the second guide bend 225. The structure of the second support rod 220a is similar to that of the first support rod 220, except that the second support rod 220a omits the first guide bend 223 and the second guide bend 225 on one side of the first support rod 220. Specifically, the second support rod 220a has the first guide bend 223 and the second guide bend 225 on the side facing the first support rod 220a, and the side of the second support rod 220a away from the first support rod 220a does not have the first guide bend 223 and the second guide bend 225, so as to facilitate the connection of the second support rod 220a to the housing of the electronic device. The structure of the third support rod 220b is similar to that of the first support rod 220.
