Folding mechanism and electronic equipment

[0001] This application claims priority to the Chinese patent application with application number 202410144739.3 filed with the State Intellectual Property Office of China on January 31, 2024, and priority to the Chinese patent application with the invention name “Folding mechanism and electronic device”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of foldable electronic products, and in particular to a folding mechanism and electronic equipment. Background Art

[0003] With the development of science and technology and the demand of the electronic equipment market, the application of foldable electronic devices is becoming more and more extensive. Traditional foldable electronic devices include a flexible screen and a folding mechanism. The folding mechanism includes a main inner shell and a shielding block. The shielding block is fixed to the end of the main inner shell. The shielding block is used to shield and protect the edge of the folding area of ​​the flexible screen. However, due to the unreasonable structural setting of the shielding block and the main inner shell, when the foldable electronic device is hit, the shielding block is easy to tip over in the direction of the folding area of ​​the flexible screen and damage the folding area of ​​the flexible screen, thereby reducing the reliability of the foldable electronic device. Summary of the Invention

[0004] The present application provides a folding mechanism and electronic equipment with better reliability.

[0005] In a first aspect, the present application provides a folding mechanism. The folding mechanism includes a main shaft, a first connecting assembly, and a second connecting assembly, wherein the main shaft is located between the first connecting assembly and the second connecting assembly, and the first connecting assembly and the second connecting assembly are both movably connected to the main shaft; the main shaft includes a main inner shell and a first blocking block; the main inner shell includes a base and a first end block, the base includes a top surface and a first end surface, the top surface of the base is connected to the first end surface of the base, and the first end block is protruded from the first end surface of the base; the first blocking block is fixedly connected to the first end block, a portion of the first blocking block is located on a side of the first end block away from the base along the length extension direction of the base, and a portion of the first blocking block extends beyond the first end block and extends to be opposite to the top surface of the base.

[0006] It can be understood that by protruding the first end block on the first end face of the base, the main inner shell has sufficient area to be fixedly connected to the first blocking block, thereby ensuring better connection firmness between the first blocking block and the main inner shell.

[0007] Furthermore, by arranging a portion of the first blocking block on a side of the first end block that is farther from the base along the longitudinal extension direction of the base, the first blocking block can rest against the first end block along the longitudinal extension direction of the base. This not only improves the connection strength between the first blocking block and the first end block, but also prevents the first blocking block from tipping toward the base after an impact with the folding mechanism.

[0008] It is understood that by providing a portion of the first blocking block to extend beyond the first end block and to face the top surface of the base, when the folding mechanism is applied to an electronic device, a portion of the first blocking block can be positioned above the second display area of ​​the flexible screen, thereby utilizing a portion of the first blocking block to cover the edge of the second display area, thereby preventing the edge of the second display area from being exposed, thereby improving the appearance of the electronic device and making it more aesthetically pleasing. Furthermore, a portion of the first blocking block can also cover the gap between the first blocking block and the second display area, thereby preventing users from scratching the second display area with their fingernails in the gap between the first blocking block and the second display area, thereby preventing damage to the second display area and improving the reliability of the flexible screen.

[0009] It is understood that when the electronic device is dropped and impacted, the first blocking block can first collide with the impacting object, thereby preventing damage to the edge of the second display area due to direct impact. In this way, the second display area is less likely to fail, which is conducive to extending the service life of the electronic device.

[0010] In a possible implementation, the first end block protrudes relative to the top surface of the base.

[0011] It can be understood that because the first end block protrudes relative to the top surface of the base, the first end block is larger and has greater structural strength. Thus, when a portion of the first shielding block is located on the side of the first end block that extends away from the base along the length of the base, the first shielding block can better support the first end block. This makes it less likely that the first shielding block will tip toward the base after an impact with the folding mechanism.

[0012] In one possible implementation, the main inner shell includes a second end block, which is protruded from the second end surface of the base, and the second end surface of the base is connected to the top surface of the base and is arranged opposite to the first end surface of the base; the main shaft includes a second blocking block, which is fixedly connected to the second end block, and a part of the second blocking block is located on the side of the second end block away from the base along the length extension direction of the base, and a part passes over the second end block and extends to be opposite to the top surface of the base.

[0013] It can be understood that by protruding the second end block on the second end face of the base, the main inner shell has sufficient area to be fixedly connected to the second blocking block, thereby ensuring better connection firmness between the second blocking block and the main inner shell.

[0014] Furthermore, by arranging a portion of the second shielding block on the side of the second end block that is farther from the base along the longitudinal extension direction of the base, the second shielding block can rest against the second end block along the longitudinal extension direction of the base. This not only improves the connection strength between the second shielding block and the second end block, but also prevents the second shielding block from tipping toward the base after an impact with the folding mechanism.

[0015] It is understood that by providing a portion of the second shielding block so as to extend beyond the second end block and to face the top surface of the base, when the folding mechanism is applied to an electronic device, a portion of the second shielding block can be positioned above the second display area of ​​the flexible screen, thereby utilizing a portion of the second shielding block to cover the edge of the second display area, thereby preventing the edge of the second display area from being exposed, thereby improving the appearance of the electronic device and making the electronic device more aesthetically pleasing. Furthermore, a portion of the second shielding block can also cover the gap between the second shielding block and the second display area, thereby preventing users from scratching the second display area with their fingernails in the gap between the second shielding block and the second display area, thereby preventing damage to the second display area and improving the reliability of the flexible screen.

[0016] It is understood that when the electronic device is dropped and impacted, the second blocking block can first collide with the impacting object, thereby preventing damage to the edge of the second display area due to direct impact. In this way, the second display area is less likely to fail, which is conducive to extending the service life of the electronic device.

[0017] In one possible implementation, the first blocking block includes a plate portion, a frame portion and a protrusion; the plate portion is located on the side of the first end block away from the base along the length extension direction of the base, the frame portion is fixedly connected to the first end block, and the protrusion is arranged opposite to the top surface of the base.

[0018] It can be understood that by fixedly connecting the frame portion to the first end block, the first shielding block can be fixed to the first end block.

[0019] Furthermore, by positioning the plate portion on the side of the first end block that is farther from the base along the length of the base, the plate portion of the first shielding block can rest against the first end block along the length of the base. This not only improves the connection strength between the first shielding block and the first end block, but also prevents the first shielding block from tipping toward the base after an impact with the folding mechanism.

[0020] Furthermore, by positioning the protrusion opposite the top surface of the base, when the folding mechanism is applied to an electronic device, the protrusion of the first shielding block can be positioned above the second display area of ​​the flexible screen. This allows the protrusion of the first shielding block to cover the edge of the second display area, preventing the edge of the second display area from being exposed, thereby improving the appearance of the electronic device and making it more aesthetically pleasing. Furthermore, the protrusion of the first shielding block can also cover the gap between the first shielding block and the second display area, preventing users from scratching the second display area with their fingernails in the gap between the first shielding block and the second display area, thereby preventing damage to the second display area and improving the reliability of the flexible screen.

[0021] It can be understood that the first blocking block of the present application has the effect of "one object with multiple uses".

[0022] In one possible implementation, the first end block is provided with a first locking groove and a second locking groove that are spaced apart; the frame portion includes a first locking portion and a second locking portion, the second locking portion is connected to the first locking portion, a portion of the first locking portion is locked and fixed in the first locking groove, and a portion of the second locking portion is locked and fixed in the second locking groove.

[0023] It is understood that by snapping a portion of the first snap-fitting portion into the first snap-fitting groove of the first end block, and snapping a portion of the second snap-fitting portion into the second snap-fitting groove of the first end block, the first shielding block and the first end block form an inverted structure. In this manner, the first shielding block and the first end block can be snap-fitted and fixed. This makes the connection between the first shielding block and the first end block simpler and more secure.

[0024] In a possible implementation, the main inner shell further includes an adhesive layer connecting the first end block and the frame portion.

[0025] It is understood that the first blocking block is fixedly connected to the first end block by both a snap-fitting method and a glue layer, thereby providing a more secure connection and improved stability. Furthermore, the area of ​​the glue layer can be reduced, which in turn reduces the area of ​​the glue dispensing region, thereby simplifying the glue dispensing process.

[0026] In a possible implementation, the frame portion is provided with a fixing groove; the first end block is provided with a first protrusion, the first protrusion is located in the fixing groove, and the adhesive layer connects the first protrusion and the groove wall of the fixing groove.

[0027] It is understandable that when the adhesive layer is formed by solidifying the glue, the fixing groove can be used to confine the glue in one area during the dispensing process, that is, to prevent the glue from overflowing into non-fixed areas.

[0028] In a possible implementation, the first protrusion protrudes relative to the first side surface of the first end block, and the opening of the fixing groove extends to the protrusion, wherein the first side surface of the first end block is connected to the first end surface of the base.

[0029] It can be understood that by arranging the first protrusion to protrude relative to the first side surface of the first end block, and by extending the opening of the fixing groove to the protrusion, the first protrusion is larger and the fixing groove is larger. This allows the first protrusion of the first end block to be more easily positioned within the fixing groove of the first shielding block, while also allowing the adhesive layer to better securely connect the first shielding block to the first end block.

[0030] In a possible implementation, the first end block is provided with a first groove, and at least a portion of the first protrusion is located in the first groove.

[0031] It can be understood that the first protrusion and the first end block have an overlapping area in the thickness direction of the main axis (that is, the Z-axis direction), that is, the first protrusion can utilize the space of the first end block in the Z-axis direction, which is conducive to the thinning setting of the main inner shell, and then conducive to the thinning setting of the folding mechanism.

[0032] In a possible implementation, at least a portion of the top surface of the protrusion is a curved surface, and in the longitudinal extension direction of the base, the curved surface bends toward a direction close to the top surface of the base.

[0033] It is understandable that when an electronic device falls and hits, the local protrusion of the first blocking block is not prone to large deformation, thereby avoiding the protrusion of the first blocking block from squeezing the flexible screen and damaging the flexible screen, that is, avoiding the problem of failure of the flexible screen, which is beneficial to extending the service life of the electronic device.

[0034] In a possible implementation, the first end block is provided with a first mounting groove, and the plate portion is located in the first mounting groove.

[0035] It can be understood that the plate portion of the first blocking block and the first end block have an overlapping area in the length extension direction of the main shaft (ie, the Y-axis direction), which is beneficial to reducing the size of the main shaft in the Y-axis direction.

[0036] In a possible implementation, the thickness of the plate portion is in a range from 0.1 mm to 0.25 mm.

[0037] It can be understood that the thinner thickness of the plate portion is conducive to the lightweight setting of the first blocking block.

[0038] In one possible implementation, the top surface of the first end block includes a first platform surface, and the top surface of the first end block and the top surface of the base face the same side; the frame portion includes a second platform surface, and the first platform surface contacts the second platform surface.

[0039] It can be understood that by setting a first platform surface on the first end block and a second platform surface on the first blocking block, the first platform surface of the first end block and the second platform surface of the first blocking block are used to form a precise fit in the Z-axis direction, which is beneficial to the accurate assembly of the first blocking block and the first end block.

[0040] In one possible implementation, when the folding mechanism is in the unfolded state, the main shaft, the first connecting component and the second connecting component jointly form a support surface; when the folding mechanism is in the folded state, the first connecting component and the second connecting component are arranged relative to each other and enclose at least part of the screen space together with the main shaft; the support surface includes the top surface of the base.

[0041] In one possible implementation, the first connecting assembly includes a first fixing frame, a first connecting member and a first support plate, the first connecting member movably connects the first fixing frame and the base of the main shaft, and the first support plate movably connects the first fixing frame and the first connecting member; the second connecting assembly includes a second fixing frame, a second connecting member and a second support plate, the second connecting member movably connects the second fixing frame and the base of the main shaft, and the second support plate movably connects the second fixing frame and the second connecting member; when the folding mechanism is in the unfolded state, the first support surface of the main shaft, the second support surface of the first support plate and the third support surface of the second support plate jointly form a support surface, and the first support surface includes the top surface of the base; when the folding mechanism is in the folded state, the second support surface and the third support surface are arranged opposite to each other, and enclose at least part of the screen space with the first support surface.

[0042] It can be understood that the structures of the first connecting component and the second connecting component in this embodiment are relatively simple.

[0043] In a second aspect, the present application provides an electronic device. The electronic device includes a first housing, a second housing, a flexible screen, and the aforementioned folding mechanism, wherein a first connecting assembly is connected to the first housing, and a second connecting assembly is connected to the second housing; the flexible screen includes a first display area, a second display area, and a third display area connected in sequence, the first display area being fixedly connected to the first housing, and the third display area being fixedly connected to the second housing; a first blocking block having a portion disposed proximate to an edge of the second display area and a portion disposed on a side of the second display area away from the top surface of the base.

[0044] It is understood that by providing a portion of the first blocking block to extend beyond the first end block and to face the top surface of the base, when the folding mechanism is applied to an electronic device, a portion of the first blocking block can be positioned above the second display area of ​​the flexible screen, thereby utilizing a portion of the first blocking block to cover the edge of the second display area, thereby preventing the edge of the second display area from being exposed, thereby improving the appearance of the electronic device and making it more aesthetically pleasing. Furthermore, a portion of the first blocking block can also cover the gap between the first blocking block and the second display area, thereby preventing users from scratching the second display area with their fingernails in the gap between the first blocking block and the second display area, thereby preventing damage to the second display area and improving the reliability of the flexible screen.

[0045] It is understood that when the electronic device is dropped and impacted, the first blocking block can first collide with the impacting object, thereby preventing damage to the edge of the second display area due to direct impact. In this way, the second display area is less likely to fail, which is conducive to extending the service life of the electronic device.

[0046] It is understandable that, since the first blocking block of the present embodiment is fixedly connected to the first end block by means of snapping and gluing, during the assembly of the electronic device, the flexible screen can be assembled to the first shell, the second shell and the main shaft before the first blocking block is installed on the first end block. In this way, interference between the first blocking block and the second display area of ​​the flexible screen can be avoided, reducing the difficulty of assembling the flexible screen and the main shaft. Since the first blocking block and the second display area of ​​the flexible screen will not interfere with each other during the assembly of the flexible screen and the main shaft, the size of the protrusion of the first blocking block can be flexibly set according to demand and is no longer restricted.

[0047] In one possible implementation, a portion of the first blocking block is spaced apart from the second display area. In other words, along the Z-axis, a gap exists between the portion of the first blocking block and the second display area of ​​the flexible screen. This prevents the flexible screen from shifting and colliding with the portion of the first blocking block when the electronic device is dropped, thereby preventing the flexible screen from failing and extending the service life of the electronic device.

[0048] In a possible implementation, the first shell includes a first abutting surface, and when the electronic device is in the folded state, the first abutting surface contacts the first blocking block.

[0049] It can be understood that by setting the first supporting surface of the first shell to contact the first blocking block when the electronic device is in a folded state, the first blocking block can support the first shell when the electronic device is colliding, thereby preventing the first shell from driving the first connecting component to fall toward the direction close to the main axis, thereby avoiding the reduction of the screen space surrounded by the first connecting component, the second connecting component and the main axis.

[0050] In a possible implementation, the second shell includes a second abutting surface, and when the electronic device is in the folded state, the second abutting surface contacts the first blocking block.

[0051] It can be understood that when the electronic device is hit, the first blocking block can support the second shell, thereby preventing the second shell from driving the second connecting component to fall toward the main axis, thereby preventing the screen space surrounded by the first connecting component, the second connecting component and the main axis from becoming smaller.

[0052] In a possible implementation, the first shell includes a first abutting surface. When the electronic device is in a flattened state, the first abutting surface is spaced apart from the first blocking block.

[0053] It is understandable that this can prevent the first shielding block from rubbing against the first housing when the electronic device switches between the flat state and the closed state. In other embodiments, when the electronic device is in the flat state, the first abutting surface of the first housing can also be arranged in contact with the first shielding block.

[0054] In a possible implementation, the second shell includes a second abutting surface. When the electronic device is in a flattened state, the second abutting surface is spaced apart from the first blocking block.

[0055] It is understandable that this can prevent the first shielding block from rubbing against the second housing when the electronic device switches between the flat state and the closed state. In other embodiments, when the electronic device is in the flat state, the second abutting surface of the second housing can also be arranged in contact with the first shielding block.

[0056] In one possible implementation, the first shell includes a main body, a first side plate, a second side plate, and a bottom plate. The first side plate, the second side plate, and the bottom plate are all connected to the same side of the main body. The first side plate and the second side plate are respectively located at two ends of the main body and are arranged opposite to each other. The bottom plate is also connected between the first side plate and the second side plate. The main body, the first side plate, the second side plate, and the bottom plate jointly surround a first assembly groove. A portion of the first connecting component is located in the first assembly groove.

[0057] It is understandable that the first abutting surface is located on the first side plate portion. In this way, the provision of the first abutting surface can utilize the space of the first side plate portion in the Z-axis direction, thereby making the structure more compact.

[0081] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0082] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "install", "connect", "connect", and "connect" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. Among them, "fixed connection" means that the two parts are connected to each other and the relative position relationship after connection remains unchanged. "Moveable connection" means that the two parts are connected to each other and can move relative to each other after connection, and the position relationship can change. In addition, two parts are obtained by an integrated structure through an integrated molding process, which means that in the process of forming one of the two parts, the part is connected to the other part, and the two parts do not need to be connected together by further processing (such as bonding, welding, snap connection, screw connection). Part A and part B are relatively arranged so that part A is projected along the target direction to obtain projection C, and part B is projected along the target direction to obtain projection D, and projection C and projection D can overlap at least in part. In some embodiments, the substantial overlap can be any of the following: projection C is completely within projection D. Or, projection D is completely within projection C. Alternatively, projection C and projection D intersect each other, and the intersection area of ​​projection C and projection D accounts for a ratio of projection C or projection D that is greater than 50%.

[0083] The directional terms mentioned in the embodiments of the present application, such as "top", "bottom", "inside", "outside", "upper", "lower", etc., are only used to refer to the directions in the drawings. Therefore, the directional terms used are for better and clearer description and understanding of the embodiments of the present application, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application. For those skilled in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0084] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship. "Multiple" means at least two.

[0085] FIG1 is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of the present application in a flattened state. FIG2 is a partial cross-sectional view of the electronic device 1000 shown in FIG1 taken along line AA. FIG3 is a schematic diagram of the structure of the electronic device 1000 shown in FIG1 in a folded state. FIG4 is a partial cross-sectional view of the electronic device 1000 shown in FIG3 taken along line BB.

[0086] As shown in Figures 1 to 4, the present application provides a foldable electronic device 1000. The foldable electronic device 1000 can be a foldable device such as a mobile phone, a tablet computer, a laptop computer, a vehicle-mounted device, or a wearable device (such as a smart bracelet). The present application embodiment is described in detail using the example of the electronic device 1000 being a mobile phone.

[0087] For ease of description, by way of example, the thickness direction of the electronic device 1000 is defined as the Z-axis direction, and the extension direction of the rotation axis of the electronic device 1000 is defined as the Y-axis direction, that is, the width direction of the electronic device 1000 is defined as the Y-axis direction. The direction perpendicular to the Y-axis direction and the Z-axis direction is defined as the X-axis direction, that is, the length direction of the electronic device 1000 is defined as the X-axis. It is understood that the coordinate system of the electronic device 1000 can also be flexibly set according to specific needs.

[0088] It can be understood that in this embodiment, the direction of the rotation axis of the electronic device 1000 is the Y-axis direction, that is, the electronic device 1000 can be relatively flattened or folded along the Y-axis direction. In this way, when the electronic device 1000 is in a folded state, the size of the electronic device 1000 in the X-axis direction becomes smaller. This embodiment is explained by taking "the direction of the rotation axis of the electronic device 1000 is the Y-axis direction" as an example. At this time, the electronic device 1000 can be folded left and right, and the folding and flattening of the electronic device 1000 affects the length dimension of the electronic device 1000. In some other embodiments, the rotation axis of the electronic device 1000 can also be the X-axis direction, that is, the electronic device 1000 can be relatively flattened or folded along the X-axis direction. At this time, the electronic device 1000 can be folded up and down, and the folding and flattening of the electronic device 1000 affects the width dimension of the electronic device 1000.

[0089] Fig. 5 is a partial exploded view of the electronic device 1000 shown in Fig. 1 in one embodiment. Fig. 6 is a partial structural diagram of the electronic device 1000 shown in Fig. 1 in one embodiment.

[0090] As shown in Figures 5 and 6, the electronic device 1000 includes a folding mechanism 100, a flexible screen 200, a first shell 300, and a second shell 400. Among them, the flexible screen 200 can be an organic light-emitting diode (OLED) display, an active matrix organic light-emitting diode or an active matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MID) display, a micro organic light-emitting diode (MID) display, or a quantum dot light-emitting diode (QLED) display. Exemplarily, the thickness direction of the folding mechanism 100 can be the Z-axis direction, and the length direction of the folding mechanism 100 can be the Y-axis direction. The width direction of the folding mechanism 100 can be the X-axis direction.

[0091] As shown in Figures 5 and 6, illustratively, the folding mechanism 100 connects the first housing 300 and the second housing 400. The folding mechanism 100 is used to relatively unfold or fold the first housing 300 and the second housing 400.

[0092] As shown in Figures 1 and 2, when the first housing 300 and the second housing 400 are relatively unfolded to a flat state, the electronic device 1000 is in a flat state, and the first housing 300 and the second housing 400 can be 180 degrees apart. In other embodiments, the first housing 300 and the second housing 400 can also have a slight deviation from 180 degrees, such as 165 degrees, 177 degrees, or 185 degrees.

[0093] As shown in Figures 3 and 4, when the first shell 300 and the second shell 400 are folded relative to each other to a closed state, the electronic device 1000 is in a folded state, the first shell 300 and the second shell 400 can be closed to each other, and there can be no large gap between the first shell 300 and the second shell 400. In this way, the appearance experience of the electronic device 1000 is better, and the waterproof, dustproof and foreign body-proof performance is better. The situation where the first shell 300 and the second shell 400 are closed includes the situation where the two are against each other, and can also include the situation where there is a small gap between the two. When there is a small gap between the first shell 300 and the second shell 400, some foreign objects outside the electronic device 1000 will not enter between the first shell 300 and the second shell 400 through the gap.

[0094] The first shell 300 and the second shell 400 can also be relatively unfolded or folded to an intermediate state, so that the electronic device 1000 is in an intermediate state. The intermediate state can be any state between the unfolded state and the folded state.

[0095] Referring to Figure 5 , and in conjunction with Figures 1 to 4 , the flexible screen 200 includes a first display area 201, a second display area 202, and a third display area 203. The second display area 202 is connected between the first display area 201 and the third display area 203. Figures 1 , 2 , and 5 all use dotted lines to schematically distinguish the first display area 201, the second display area 202, and the third display area 203. The first display area 201 of the flexible screen 200 is fixed to the first shell 300. The third display area 203 is fixed to the second shell 400. During the relative expansion or folding of the first shell 300 and the second shell 400, the first shell 300 can drive the first display area 201 to move, and the second shell 400 can drive the third display area 203 to move. The first display area 201 and the third display area 203 are relatively expanded or folded, and the second display area 202 can deform.

[0096] It can be understood that since the first display area 201 is fixed to the first shell 300 and the third display area 203 is fixed to the second shell 400, when the first shell 300 and the second shell 400 are relatively unfolded or folded, the relative unfolding and folding movements between the first display area 201 and the third display area 203 can be accurately controlled, so that the folding process and movement form of the flexible screen 200 are controllable and the reliability is relatively high.

[0097] As shown in Figures 1 and 2, when the electronic device 1000 is in a flattened state, the flexible screen 200 can be in a flattened state. For example, the first display area 201, the second display area 202, and the third display area 203 of the flexible screen 200 can be 180 degrees. In other embodiments, the first display area 201, the second display area 202, and the third display area 203 can also have a slight deviation from 180 degrees, such as 165 degrees, 177 degrees, or 185 degrees. In this case, the flexible screen 200 has a continuous large display area, that is, the flexible screen 200 can achieve large-screen display, and the user experience is better.

[0098] For example, when the electronic device 1000 is in a flattened state, at least a portion of the folding mechanism 100 can be used to support the second display area 202. Thus, when the second display area 202 is subjected to pressing, squeezing, or impact forces, the folding mechanism 100 can be used to improve the second display area 202's ability to withstand pressure and impact, thereby preventing the second display area 202 from denting.

[0099] As shown in Figures 3 and 4, when the electronic device 1000 is in a folded state, the flexible screen 200 is in a folded state. For example, the first display area 201 and the third display area 203 of the flexible screen 200 are close to each other. The second display area 202 is bent. At this time, the flexible screen 200 can be roughly in the shape of a "water drop". In addition, the flexible screen 200 is located in the space surrounded by the first shell 300, the folding mechanism 100 and the second shell 400. The first display area 201 and the third display area 203 are located between the first shell 300 and the second shell 400. At this time, the plane size of the electronic device 1000 is small (with a smaller width dimension), which is convenient for users to carry and store.

[0100] Fig. 7 is a partially exploded view of an embodiment of the folding mechanism 100 shown in Fig. 5. Fig. 8 is a schematic structural diagram of the folding mechanism 100 shown in Fig. 5 at another angle.

[0101] Referring to Figures 7 and 8 , in conjunction with Figures 5 and 6 , the folding mechanism 100 includes a main shaft 1, a first connecting assembly 2, and a second connecting assembly 3. The main shaft 1 is located between the first connecting assembly 2 and the second connecting assembly 3, and both the first connecting assembly 2 and the second connecting assembly 3 are movably connected to the main shaft 1. For example, the main shaft 1 may extend in the Y-axis direction.

[0102] Illustratively, the main shaft 1 is also located between the first housing 300 and the second housing 400. The first connecting assembly 2 is also connected to the first housing 300. The second connecting assembly 3 is also connected to the second housing 400. It is understood that through the mutual cooperation of the first connecting assembly 2 and the second connecting assembly 3, the first housing 300 and the second housing 400 can be relatively expanded or folded.

[0103] As shown in Figure 2, when the first shell 300 and the second shell 400 are relatively unfolded to a flattened state (that is, the electronic device 1000 is in a flattened state), the first connecting component 2 and the second connecting component 3 are opened relative to the main axis 1, and the main axis 1, the first connecting component 2 and the second connecting component 3 can form a support surface 100b, and the support surface 100b is used to support the second display area 202 of the flexible screen 200, so that when the second display area 202 is touched, the second display area 202 is not easily damaged or dented due to external force, thereby significantly improving the reliability of the flexible screen 200.

[0104] As shown in Figure 4, when the electronic device 1000 is in the folded state, the main axis 1 is located between the first connecting component 2 and the second connecting component 3, and the first connecting component 2 and the second connecting component 3 are close to each other. The first connecting component 2 and the second connecting component 3 are arranged opposite each other. The main axis 1, the first connecting component 2 and the second connecting component 3 can enclose at least a portion of the screen space 100a. The second display area 202 of the flexible screen 200 can be located within the screen space 100a.

[0105] The above text, in conjunction with the relevant drawings, specifically describes that the folding mechanism 100 includes a main shaft 1, a first connecting component 2, and a second connecting component 3, and the main shaft 1 is connected to the first shell 300 and the second shell 400 respectively through the first connecting component 2 and the second connecting component 3. It is understandable that the specific structure of the first connecting component 2 and the second connecting component 3 can be set in a variety of ways. Specifically, this application does not limit it. In order to more clearly illustrate the connection method between the folding mechanism 100 and the flexible screen 200, the first shell 300, and the second shell 400, the following text will only schematically introduce a structure of the first connecting component 2 and the second connecting component 3 in conjunction with the relevant drawings.

[0106] As shown in Figures 7 and 8 , the first connecting assembly 2 includes a first fixing bracket 21, a first connecting member 22, and a first support plate 23. It is understood that the number, shape, and size of the first fixing bracket 21 and the first connecting member 22 are not limited to those illustrated in Figure 7 . This is not specifically limited in this embodiment.

[0107] As shown in Figures 7 and 8, the first connecting member 22 movably connects the first fixing frame 21 and the main shaft 1. The first support plate 23 movably connects the first fixing frame 21 and the first connecting member 22. It will be understood that the specific connection method of the first connecting member 22, the first fixing frame 21, and the main shaft 1, and the specific connection method of the first support plate 23, the first fixing frame 21, and the first connecting member 22 are not specifically limited in this embodiment.

[0108] As shown in Figures 7 and 8, the second connecting assembly 3 includes a second fixing frame 31, a second connecting member 32, and a second support plate 33. The second connecting member 32 movably connects the second fixing frame 31 and the main shaft 1. The second support plate 33 movably connects the second fixing frame 31 and the second connecting member 32. It is understandable that the second connecting assembly 3 and the first connecting assembly 2 can be similar or identical structures, symmetrical or partially symmetrical structures, or different structures. In this embodiment, the second connecting assembly 3 and the first connecting assembly 2 are similar structures. The basic design of the component structure of the second connecting assembly 3, the connection relationship design between the components, and the connection relationship design between the components and other structures outside the assembly can all refer to the relevant scheme of the first connecting assembly 2. At the same time, the second connecting assembly 3 and the first connecting assembly 2 are allowed to have slight differences in the detailed structure or position arrangement of the components. The details will not be repeated here.

[0109] As shown in Figures 5 and 6, and in conjunction with Figures 7 and 8, the first fixing frame 21 can be fixedly connected to the first housing 300. The second fixing frame 31 can be fixedly connected to the second housing 400. It is understood that the fixing connection method between the first fixing frame 21 and the first housing 300, and the fixing connection method between the second fixing frame 31 and the second housing 400 are not specifically limited in this application. For example, they can be fixedly connected using fasteners (screws, pins, etc.), snap-fit ​​connection, or adhesive connection.

[0110] It is understandable that, because the first fixing frame 21 is fixedly connected to the first housing 300, the second fixing frame 31 is fixedly connected to the second housing 400, the first connecting member 22 is movably connected to the first fixing frame 21 and the main shaft 1, and the second connecting member 32 is movably connected to the second fixing frame 31 and the main shaft 1, the first housing 300 and the second housing 400 can be connected to each other through the first fixing frame 21, the first connecting member 22, the second connecting member 32, and the second fixing frame 31. In this way, when the electronic device 1000 switches from the flat state to the folded state, the first housing 300 and the second housing 400 move closer to each other, the first housing 300 can drive the first connecting member 22 to move relative to the main shaft 1 via the first fixing frame 21, and the second housing 400 can drive the second connecting member 32 to move relative to the main shaft 1 via the second fixing frame 31. When the electronic device 1000 switches from a folded state to a flattened state, the first shell 300 and the second shell 400 open to each other, the first shell 300 can drive the first connecting member 22 to move relative to the main axis 1 through the first fixing frame 21, and the second shell 400 can drive the second connecting member 32 to move relative to the main axis 1 through the second fixing frame 31.

[0111] It can be understood that since the first support plate 23 movably connects the first fixing frame 21 and the first connecting member 22, and the second support plate 33 movably connects the second fixing frame 31 and the second connecting member 32, when the electronic device 1000 switches from the flat state to the folded state, the first shell 300 can also drive the first support plate 23 to move relative to the main axis 1 through the first fixing frame 21, and the second shell 400 can also drive the second support plate 33 to move relative to the main axis 1 through the second fixing frame 31. In addition, when the electronic device 1000 switches from the folded state to the flat state, the first support plate 23 and the second support plate 33 can be opened relative to the main axis 1.

[0112] As shown in Figures 5 and 6, the spindle 1 includes, for example, a first support surface 10. The first support surface 10 can be a plane. The first support plate 23 has a second support surface 231. The second support surface 231 can be a plane. The second support plate 33 has a third support surface 331. The third support surface 331 can be a plane.

[0113] As shown in FIG2 , when the electronic device 1000 is in a flat state, the first supporting surface 10 of the main shaft 1 , the second supporting surface 231 of the first supporting plate 23 , and the third supporting surface 331 of the second supporting plate 33 may form a supporting surface 100 b .

[0114] As shown in FIG4 , when the electronic device 1000 is in the folded state, the first support surface 10 of the main shaft 1 , the second support surface 231 of the first support plate 23 , and the third support surface 331 of the second support plate 33 can enclose at least a portion of the screen space 100 a .

[0115] The above description specifically describes an embodiment of the structure of the first connecting assembly 2 and the second connecting assembly 3 in conjunction with the relevant drawings. The following description specifically describes an embodiment of the structure of the main shaft 1 in conjunction with the relevant drawings.

[0116] Fig. 9 is a partially exploded view of an embodiment of the main shaft 1 shown in Fig. 7. Fig. 10 is a partially exploded view of the main shaft 1 shown in Fig. 9 at another angle.

[0117] As shown in Figures 9 and 10, the main shaft 1 includes a main inner housing 11, a main outer housing 12, a first blocking block 13, and a second blocking block 14. It is understood that the main shaft 1 may include fewer or more structures. For example, when the main shaft 1 includes fewer structures, the main outer housing 12 and / or the second blocking block 14 may not be required.

[0118] As shown in Figures 9 and 10, the main inner shell 11 includes a base 111, a first end block 112, and a second end block 113. For example, the base 111 may extend in the Y-axis direction. In other embodiments, the main inner shell 11 may not include the second end block 113.

[0119] Exemplarily, the base 111 includes a top surface 1111 and a bottom surface 1112 disposed in opposite directions, as well as a first end surface 1113 and a second end surface 1114 disposed in opposite directions. The first end surface 1113 and the second end surface 1114 of the base 111 are connected between the top surface 1111 and the bottom surface 1112 of the base 111. The top surface 1111 of the base 111 is a portion of the first supporting surface 10 (see FIG. 6 ) of the spindle 1, that is, the first supporting surface 10 of the spindle 1 includes the top surface 1111 of the base 111. The first end surface 1113 and the second end surface 1114 of the base 111 may be the two end surfaces of the base 111 in the Y-axis direction.

[0120] For example, the first end block 112 can be protruded from the first end surface 1113 of the base 111. It is understood that the first end block 112 and the base 111 in this embodiment are integrally formed. In other embodiments, the first end block 112 can also be fixedly connected to the base 111 by other fixing methods such as bonding or snapping.

[0121] Exemplarily, the first end block 112 protrudes relative to the top surface 1111 of the base 111. In other words, in the Z-axis direction, the first end block 112 is higher than the top surface 1111 of the base 111. In this way, the volume of the first end block 112 is larger and the structural strength of the first end block 112 is better.

[0122] Exemplarily, the second end block 113 can be protruding from the second end surface 1114 of the base 111. It is understandable that the second end block 113 and the first end block 112 can be the same structure, symmetrical structure, partially symmetrical structure or different structure, and this application does not strictly limit this. Exemplarily, the second end block 113 and the first end block 112 can be symmetrical structures. Among them, the basic design of the component structure of the second end block 113, the connection relationship design between the components, and the connection relationship design between the components and other structures outside the assembly can all refer to the relevant schemes of the first end block 112, while allowing the second end block 113 and the first end block 112 to be slightly different in the detailed structure or position arrangement of the components. The following description will be made using the first end block 112 as an example. Regarding the setting method of the second end block 113, it will not be repeated below.

[0123] Fig. 11 is an enlarged view of the main shaft 1 at position C shown in Fig. 9. Fig. 12 is an enlarged view of the main shaft 1 at position D shown in Fig. 10.

[0124] As shown in Figures 11 and 12, the first end block 112 includes a top surface 112a and a bottom surface 112b facing away from each other, a first side surface 112c and a second side surface 112d facing away from each other, and a third side surface 112e and a fourth side surface 112f facing away from each other. The first side surface 112c and the second side surface 112d of the first end block 112 are connected between the top surface 112a and the bottom surface 112b of the first end block 112. The third side surface 112e and the fourth side surface 112f of the first end block 112 are connected between the top surface 112a and the bottom surface 112b of the first end block 112, and between the first side surface 112c and the second side surface 112d of the first end block 112. It is understood that the first side surface 112c of the first end block 112 is connected to the first end surface 1113 of the base 111. The top surface 112a of the first end block 112 and the top surface 1111 of the base 111 may face the same side.

[0125] Exemplarily, the first end block 112 is provided with a first locking groove 1121 and a second locking groove 1122 which are spaced apart from each other.

[0126] For example, the first retaining groove 1121 may be formed with openings on the bottom surface 112b, the first side surface 112c, the second side surface 112d, and the third side surface 112e of the first end block 112. In other embodiments, the opening position, shape, and size of the first retaining groove 1121 are not specifically limited. For example, the first retaining groove 1121 may be formed with openings only on the bottom surface 112b and the third side surface 112e of the first end block 112.

[0127] For example, the second retaining groove 1122 may be formed with openings on the bottom surface 112b, the first side surface 112c, the second side surface 112d, and the fourth side surface 112f of the first end block 112. In other embodiments, the opening position, shape, and size of the second retaining groove 1122 are not specifically limited. For example, the first retaining groove 1121 may also be formed with openings only on the bottom surface 112b and the fourth side surface 112f of the first end block 112.

[0128] For example, a first protrusion 1123 is provided on the top surface 112a of the first end block 112. It is understood that the first protrusion 1123 of this embodiment can be integrally formed with the first end block 112. In other embodiments, the first protrusion 1123 can also be fixedly connected to the first end block 112 via other fixing methods such as bonding or snap-fitting. Furthermore, this application does not specifically limit the shape, size, or number of the first protrusions 1123.

[0129] Exemplarily, the first protrusion 1123 protrudes relative to the first side surface 112c of the first end block 112. In this way, the volume of the first protrusion 1123 is larger, thereby better improving the structural strength of the first end block 112.

[0130] For example, the first end block 112 is provided with a first groove 1124. The first groove 1124 may form openings on the top surface 112a, the first side surface 112c, and the second side surface 112d of the first end block 112. In other embodiments, the opening position, shape, and size of the first groove 1124 are not specifically limited. For example, the first groove 1124 may only form an opening on the top surface 112a of the first end block 112.

[0131] At least a portion of the first protrusion 1123 is located within the first groove 1124. Thus, the first protrusion 1123 and the first end block 112 have an overlapping area in the Z-axis direction. That is, the first protrusion 1123 can utilize the space of the first end block 112 in the Z-axis direction, thereby facilitating a thinner configuration of the main inner housing 11 and, in turn, a thinner configuration of the folding mechanism 100.

[0132] As shown in Figures 11 and 12, the top surface 112a of the first end block 112 includes a first platform surface 1125 (also referred to as a first plane 1125). For example, there may be two first platform surfaces 1125, one located on either side of the first groove 1124. In other embodiments, the number, shape, size, and position of the first platform surfaces 1125 are not specifically limited in this embodiment.

[0133] Illustratively, the first end block 112 is provided with a first mounting groove 1126. The first mounting groove 1126 may form openings on the top surface 112a, the second side surface 112d, the third side surface 112e, and the fourth side surface 112f of the first end block 112. In other embodiments, the opening position, shape, and size of the first mounting groove 1126 are not specifically limited. For example, the first mounting groove 1126 may only form openings on the top surface 112a and the second side surface 112d of the first end block 112.

[0134] Figure 13 is a schematic diagram of the structure of the first shielding block 13 shown in Figure 9 at different angles. Figure 14 is a schematic diagram of the structure of the first shielding block 13 shown in Figure 9 at another angle.

[0135] As shown in Figures 13 and 14, the first shielding block 13 includes a plate portion 131, a frame portion 132, and a protrusion 133. For example, the first shielding block 13 is an integrally formed structural member. In this way, the integrity of the first shielding block 13 is better.

[0136] Exemplarily, the frame portion 132 is connected to the edge of the plate portion 131 . The frame portion 132 and the plate portion 131 enclose an accommodating space 134 . In addition, the protrusion 133 is protruded from the surface of the frame portion 132 away from the plate portion 131 .

[0137] Exemplarily, the thickness of the plate portion 131 is in the range of 0.05 mm to 0.35 mm. For example, the thickness of the plate portion 131 is 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.3 mm, or 0.35 mm. It is understood that a thinner thickness of the plate portion 131 facilitates a lightweight configuration of the first shielding block 13.

[0138] Exemplarily, the thickness of the plate portion 131 is in the range of 0.1 mm to 0.25 mm. For example, the thickness of the plate portion 131 is 0.1 mm, 0.15 mm, 0.2 mm, or 0.25 mm. It is understood that a thinner thickness of the plate portion 131 facilitates a lightweight configuration of the first shielding block 13.

[0139] Illustratively, the frame portion 132 includes a first engaging portion 1321 and a second engaging portion 1322. The second engaging portion 1322 is connected to the first engaging portion 1321. The end of the first engaging portion 1321 away from the second engaging portion 1322 is hook-shaped. The end of the second engaging portion 1322 away from the first engaging portion 1321 is hook-shaped. In other embodiments, the end of the first engaging portion 1321 away from the second engaging portion 1322 may also have other shapes, and the end of the second engaging portion 1322 away from the first engaging portion 1321 may also have other shapes. This embodiment is not limited to this.

[0140] Exemplarily, both the first engaging portion 1321 and the second engaging portion 1322 are in a "C" shape.

[0141] Exemplarily, the frame portion 132 is provided with a fixing groove 1323. The opening of the fixing groove 1323 is formed on the surface of the frame portion 132 facing the accommodating space 134. At this time, the fixing groove 1323 communicates with the accommodating space 134.

[0142] As shown in FIGS. 13 and 14, the frame portion 132 of the first shielding block 13 includes a second platform surface 1324 (also referred to as the second plane 1324). Exemplarily, the number of the second platform surfaces 1324 can be two, and the two second platform surfaces 1324 are respectively located on both sides of the fixing groove 1323. In other embodiments, the number, shape, size and position of the second platform surface 1324 are not specifically limited in this embodiment.

[0143] Exemplarily, the opening of the fixing groove 1323 can extend to the convex portion 133. In this way, the size of the fixing groove 1323 is larger.

[0144] As shown in FIGS. 13 and 14, at least a part of the top surface 1331 of the convex portion 133 of the first shielding block 13 is a curved surface. Exemplarily, the curved surface is curved in the negative direction of the Z axis in the positive direction of the Y axis. At this time, at least a part of the top surface 1331 of the convex portion 133 of the first shielding block 13 can form an arc in the negative direction of the Z axis.

[0145] FIG. 15 is a partial structural schematic diagram of the main shaft 1 shown in FIG. 7 in one embodiment. FIG. 16 is a partial structural schematic diagram of the main shaft 1 shown in FIG. 15 from another angle. FIG. 17 is a partial cross-sectional view of a part of the main shaft 1 shown in FIG. 16 at the E-E line in one embodiment.

[0146] Referring to Figures 15 to 17 , and in conjunction with Figures 11 to 14 , the first shielding block 13 is fixedly connected to the first end block 112. At least a portion of the first end block 112 is located within the accommodating space 134. The plate portion 131 of the first shielding block 13 is located on the side of the first end block 112 away from the base 111. A portion of the frame portion 132 of the first shielding block 13 is located on the side of the top surface 112a of the first end block 112. A portion of the frame portion 132 of the first shielding block 13 is located on the side of the third side surface 112e of the first end block 112. A portion of the frame portion 132 of the first shielding block 13 is located on the side of the fourth side surface 112f of the first end block 112. The protrusion 133 of the first shielding block 13 is located on the side of the top surface 1111 of the base 111, spaced apart from and disposed opposite the top surface 1111 of the base 111. In other words, a portion of the first blocking block 13 is located on the side of the first end block 112 away from the base 111, and a portion passes over the top surface 112a of the first end block 112 and extends to the side of the top surface 1111 of the base 111, and is spaced apart from and opposite to the top surface 1111 of the base 111.

[0147] It is understood that the plate portion 131 of the first shielding block 13 is located on the side of the first end block 112 that is farther away from the base 111 along the length of the base 111 (i.e., the Y-axis direction). The plate portion 131 of the first shielding block 13 can rest against the first end block 112. This not only improves the connection between the first shielding block 13 and the first end block 112, but also prevents the first shielding block 13 from tipping toward the base 111 (i.e., the positive direction of the Y-axis) after the folding mechanism 100 is impacted.

[0148] It can be understood that because the first end block 112 protrudes relative to the top surface 1111 of the base 111, the first end block 112 is larger and has greater structural strength. Thus, when the plate portion 131 of the first shielding block 13 is located on the side of the first end block 112 away from the base 111 along the Y-axis, the first shielding block 13 can better support the first end block 112. When the folding mechanism 100 is impacted, the first shielding block 13 is less likely to tip toward the base 111 (i.e., in the positive direction of the Y-axis).

[0149] Referring to Figures 15 to 17 , and in conjunction with Figures 11 to 14 , the frame portion 132 is fixedly connected to the first end block 112. For example, a portion of the first engaging portion 1321 is engaged and fixed within the first engaging groove 1121 of the first end block 112. A portion of the second engaging portion 1322 is engaged and fixed within the second engaging groove 1122 of the first end block 112.

[0150] Exemplarily, the end of the first engaging portion 1321 away from the second engaging portion 1322 is hooked on the wall of the first engaging slot 1121 . The end of the second engaging portion 1322 away from the first engaging portion 1321 is hooked on the wall of the second engaging slot 1122 .

[0151] It is understood that by having a portion of the first engaging portion 1321 engaged and fixed within the first engaging groove 1121 of the first end block 112, and a portion of the second engaging portion 1322 engaged and fixed within the second engaging groove 1122 of the first end block 112, the first shielding block 13 and the first end block 112 form an inverted structure. In this manner, the first shielding block 13 and the first end block 112 can be engaged and fixed. This makes the connection between the first shielding block 13 and the first end block 112 simpler and more secure.

[0152] As shown in FIG17 , and in conjunction with FIG11 to FIG14 , the first protrusion 1123 of the first end block 112 is positioned within the fixing groove 1323 of the first shielding block 13. The main inner housing 11 further includes an adhesive layer 114. Adhesive layer 114 connects the first protrusion 1123 to the walls of the fixing groove 1323. At this point, the first shielding block 13 can be further fixedly connected to the first end block 112 via the adhesive layer 114.

[0153] In this embodiment, the first blocking block 13 is fixedly connected to the first end block 112 by both a snap-fitting method and an adhesive layer 114. This provides a more secure connection and improved stability between the first blocking block 13 and the first end block 112. Furthermore, the area of ​​the adhesive layer 114 can be reduced, which in turn reduces the area of ​​the adhesive dispensing region, thereby simplifying the adhesive dispensing process.

[0154] It is understandable that when the glue layer 114 is formed by curing glue, the fixing groove 1323 can be used to confine the glue in one area during the dispensing process, that is, to prevent the glue from overflowing into non-fixed areas.

[0155] It is understood that by arranging the first protrusion 1123 to protrude relative to the first side surface 112c of the first end block 112 and extending the opening of the fixing groove 1323 to the convex portion 133, the volume of the first protrusion 1123 and the size of the fixing groove 1323 are increased. In this manner, the first protrusion 1123 of the first end block 112 can be better positioned within the fixing groove 1323 of the first shielding block 13; and the adhesive layer 114 can better securely connect the first shielding block 13 to the first end block 112.

[0156] As shown in FIG15 , and in conjunction with FIG11 to FIG14 , the plate portion 131 of the first blocking block 13 is located within the first mounting groove 1126. Thus, the plate portion 131 of the first blocking block 13 and the first end block 112 have an overlapping area in the Y-axis direction, thereby facilitating a reduction in the size of the spindle 1 in the Y-axis direction.

[0157] As shown in FIG15 , and in conjunction with FIG11 to FIG14 , the surface of the protrusion 133 of the plate portion 131 of the first blocking block 13 away from the first blocking block 13 is flush with the second side surface 112d of the first end block 112. This improves the appearance consistency of the spindle 1 and makes the spindle 1 more aesthetically pleasing.

[0158] FIG18 is a partial cross-sectional view of a portion of the main shaft 1 shown in FIG15 at line FF according to an embodiment.

[0159] As shown in FIG18 , and in conjunction with FIG11 to FIG14 , the first platform surface 1125 of the first end block 112 contacts the second platform surface 1324 of the first blocking block 13. For example, when there are multiple first platform surfaces 1125 of the first end block 112 and multiple second platform surfaces 1324 of the first blocking block 13, the multiple first platform surfaces 1125 and the multiple second platform surfaces 1324 are arranged in contact with each other in a one-to-one correspondence.

[0160] It can be understood that by setting the first platform surface 1125 on the first end block 112 and setting the second platform surface 1324 on the first blocking block 13, the first platform surface 1125 of the first end block 112 and the second platform surface 1324 of the first blocking block 13 are used to form a precise fit in the Z-axis direction, which is beneficial to the accurate assembly of the first blocking block 13 and the first end block 112.

[0161] As shown in Figures 15 and 16, the second shielding block 14 is fixedly connected to the second end block 113. A portion of the second shielding block 14 is located on the side of the second end block 113 away from the base 111 along the Y-axis, while a portion extends beyond the second end block 113 to face the top surface 1111 of the base 111. It is understood that the second shielding block 14 and the first shielding block 13 can have the same structure, a symmetrical structure, a partially symmetrical structure, or different structures, and this is not strictly limited in this application. For example, the second shielding block 14 and the first shielding block 13 can have symmetrical structures. The basic design of the component structure of the second end block 113, the design of the connection relationship between the components, and the design of the connection relationship between the components and other structures outside the assembly can refer to the relevant embodiments of the first end block 112. However, slight differences in the detailed structure or positional arrangement of the components of the second end block 113 and the first end block 112 are permitted. The following description will use the first end block 112 as an example. The configuration of the second end block 113 will not be further elaborated below.

[0162] FIG19 is a partial structural diagram of an embodiment of the main shaft 1 shown in FIG7 .

[0163] As shown in FIG19 , the main housing 12 encloses a receiving space 121 ( FIG9 and FIG10 also illustrate the receiving space 121 from different angles). For example, the main housing 12 may be in a strip shape. The length of the main housing 12 may extend in the Y-axis direction.

[0164] Referring to Figure 19 , and in conjunction with Figures 16 to 18 , the main inner shell 11 is fixedly connected to the main outer shell 12 and is at least partially located within the accommodation space 121. For example, at least a portion of the base 111 of the main inner shell 11 is located within the accommodation space 121 of the main outer shell 12. The bottom surface 1112 of the base 111 of the main inner shell 11 faces the accommodation space 121 of the main outer shell 12. The top surface 1111 of the base 111 of the main inner shell 11 faces away from the main outer shell 12 and is exposed relative to the main outer shell 12. It is understood that the main outer shell 12 can cover the base 111 of the main inner shell 11 from one side of the bottom surface 1112 of the base 111 of the main inner shell 11. Furthermore, the first end piece 112 and the second end piece 113 of the main inner shell 11 can be exposed relative to the main outer shell 12, meaning that the main outer shell 12 does not need to cover the first end piece 112 and the second end piece 113.

[0165] It is understood that the structure of the main outer shell 12, the connection relationship between the main outer shell 12 and the main inner shell 11, and the positional relationship between the main outer shell 12 and the main inner shell 11 are not limited to the structure shown in Figure 19. In other embodiments, the structure of the main outer shell 12, the connection relationship between the main outer shell 12 and the main inner shell 11, and the positional relationship between the main outer shell 12 and the main inner shell 11 are not specifically limited.

[0166] FIG20 is a schematic structural diagram of an embodiment of the electronic device 1000 shown in FIG1 at another angle.

[0167] As shown in FIG20 , when the electronic device 1000 is in a flattened state, the first shielding block 13 is located between the first housing 300 and the second housing 400 . The plate portion 131 and the frame portion 132 of the first shielding block 13 are positioned near the edge of the second display area 202 and spaced apart from the edge of the second display area 202 . The protrusion 133 of the first shielding block 13 is located on a side of the second display area 202 of the flexible screen 200 that is away from the base 111 (see FIG19 ). In other words, a portion of the second display area 202 of the flexible screen 200 is located between the protrusion 133 of the first shielding block 13 and the base 111 . In other words, the protrusion 133 of the first shielding block 13 is located above the second display area 202 of the flexible screen 200. It will be understood that the size of the protrusion 133 of the first shielding block 13 above the second display area 202 of the flexible screen 200 can be flexibly set according to needs and is not specifically limited in this application.

[0168] It can be understood that by positioning the plate portion 131 and the frame portion 132 of the first shielding block 13 near the edge of the second display area 202 and spaced apart from the edge of the second display area 202, and positioning the protrusion 133 of the first shielding block 13 above the second display area 202 of the flexible screen 200, the protrusion 133 of the first shielding block 13 covers the edge of the second display area 202, thereby preventing the edge of the second display area 202 from being exposed, thereby improving the appearance of the electronic device 1000 and making the electronic device 1000 more beautiful. In addition, the protrusion 133 of the first shielding block 13 can also cover the gap between the first shielding block 13 and the second display area 202, thereby preventing users from scratching the second display area 202 with their fingernails in the gap between the first shielding block 13 and the second display area 202, thereby preventing damage to the second display area 202 and improving the reliability of the flexible screen 200.

[0169] It is understood that when the electronic device 1000 is dropped and impacted, the first blocking block 13 can first collide with the impacting object, thereby preventing damage to the edge of the second display area 202 due to direct impact. In this way, the second display area 202 is less likely to fail, which is conducive to extending the service life of the electronic device 1000.

[0170] It can be understood that, in conjunction with Figures 19 and 20, since the first blocking block 13 of this embodiment is fixedly connected to the first end block 112 by means of snapping and gluing, during the assembly process of the electronic device 1000, the flexible screen 200 can be first assembled to the first shell 300, the second shell 400, and the main shaft 1, and then the first blocking block 13 can be installed on the first end block 112. In this way, interference between the first blocking block 13 and the second display area 202 of the flexible screen 200 can be avoided, reducing the difficulty of assembling the flexible screen 200 and the main shaft 1. Since the first blocking block 13 and the second display area 202 of the flexible screen 200 do not interfere with each other during the assembly of the flexible screen 200 and the main shaft 1, the size of the protrusion 133 of the first blocking block 13 can be flexibly set according to needs and is no longer restricted.

[0171] For example, when the electronic device 1000 is in a flattened state, the protrusion 133 of the first shielding block 13 is spaced apart from the second display area 202 of the flexible screen 200. That is, in the Z-axis direction, there is a gap between the protrusion 133 of the first shielding block 13 and the second display area 202 of the flexible screen 200. This prevents the flexible screen 200 from shifting and colliding with the protrusion 133 of the first shielding block 13 when the electronic device 1000 is dropped, thereby preventing failure of the flexible screen 200 and extending the service life of the electronic device 1000.

[0172] As shown in Figures 13 and 20, at least a portion of the top surface 1331 of the convex portion 133 of the first shielding block 13 is a curved surface, and in the positive direction of the Y axis, the curved surface bends toward the negative direction of the Z axis, that is, toward the flexible screen 200. In this way, when the electronic device 1000 is dropped and impacted, the convex portion 133 of the first shielding block 13 is less likely to undergo significant deformation, thereby preventing the convex portion 133 of the first shielding block 13 from squeezing the flexible screen 200 and damaging it. In other words, it prevents the flexible screen 200 from failing, which helps to extend the service life of the electronic device 1000.

[0173] FIG. 21 is a schematic diagram showing the first shell 300 and the second shell 400 shown in FIG. 1 being separated from each other in one embodiment.

[0174] Referring to FIG. 21 , and in conjunction with FIG. 20 , the first housing 300 includes a first abutting surface 301. The first abutting surface 301 faces the first blocking block 13. The first abutting surface 301 may be a plane. It is understood that the shape, size, and position of the first abutting surface 301 are not specifically limited in this embodiment.

[0175] Exemplarily, the first shell 300 includes a main body 302, a first side plate 303, a second side plate 304 and a bottom plate 305. The first side plate 303, the second side plate 304 and the bottom plate 305 are all connected to the same side of the main body 302. The first side plate 303 and the second side plate 304 are respectively located at the two ends of the main body 302 and are arranged opposite to each other. The bottom plate 305 is also connected between the first side plate 303 and the second side plate 304. The main body 302, the first side plate 303, the second side plate 304 and the bottom plate 305 can jointly enclose a first assembly groove 306. The first assembly groove 306 can be used to accommodate at least a portion of the first connecting component 2 (that is, at least a portion of the first connecting component 2 is located in the first assembly groove 306), such as the first fixing bracket 21. It is understood that although the first housing 300 is described as being divided into four parts in this embodiment, this does not affect the fact that the first housing 300 can be an integrally formed structure, that is, the main body 302, the first side panel 303, the second side panel 304, and the bottom panel 305 can be integrally formed. In other embodiments, the first housing 300 can also be assembled from separate components.

[0176] As shown in Figure 21, the first abutting surface 301 is located on the first side plate portion 303. For example, the first abutting surface 301 can be a groove wall of the groove of the first side plate portion 303 facing away from the main body portion 302, or can be a surface of the protrusion of the first side plate portion 303 facing away from the main body portion 302. This embodiment is not limited to this.

[0177] As shown in Figure 20, when the electronic device 1000 is in the flattened state, the first abutting surface 301 of the first housing 300 is spaced apart from the first blocking block 13. This prevents the first blocking block 13 from rubbing against the first housing 300 when the electronic device 1000 switches between the flattened and closed states. In other embodiments, the first abutting surface 301 of the first housing 300 may also be in contact with the first blocking block 13 when the electronic device 1000 is in the flattened state.

[0178] FIG22 is a partial cross-sectional view of the electronic device 1000 shown in FIG3 taken along line GG according to an embodiment.

[0179] 22 , when the electronic device 1000 is in the folded state, the first abutting surface 301 of the first housing 300 contacts the first blocking block 13 . Exemplarily, the first abutting surface 301 of the first housing 300 contacts the frame portion 132 of the first blocking block 13 .

[0180] As shown in FIG4 , in some electronic devices 1000 , when the electronic device 1000 is dropped and impacted, the first housing 300 and the second housing 400 can easily cause the first connecting component 2 and the second connecting component 3 to fall toward the main axis 1 , thereby reducing the screen space 100a enclosed by the first connecting component 2, the second connecting component 3, and the main axis 1. It is understood that the screen space 100a is used to accommodate the second display area 202 of the flexible screen 200. If the screen space 100a is small, the second display area 202 of the flexible screen 200 has less room for free deformation, the second display area 202 is more curved, and the second display area 202 is easily damaged. Please refer to Figure 22, and in combination with Figure 4, in this embodiment, by setting it so that when the electronic device 1000 is in a folded state, the first supporting surface 301 of the first shell 300 contacts the first blocking block 13, so that when the electronic device 1000 is hit, the first blocking block 13 can support the first shell 300, thereby preventing the first shell 300 from driving the first connecting component 2 to fall toward the direction close to the main axis 1, thereby preventing the screen space 100a surrounded by the first connecting component 2, the second connecting component 3 and the main axis 1 from becoming smaller.

[0181] In other embodiments, when the electronic device 1000 is in the folded state, the first abutting surface 301 of the first housing 300 may also be spaced apart from the first blocking block 13. Specifically, the space may be flexibly set according to needs.

[0182] As shown in FIG. 21 and FIG. 22 , and in combination with FIG. 4 , the second housing 400 includes a second abutting surface 401 .

[0183] When the electronic device 1000 is in the flattened state, the second abutting surface 401 of the second housing 400 is spaced apart from the first blocking block 13. This prevents the first blocking block 13 from rubbing against the second housing 400 when the electronic device 1000 switches between the flattened and closed states. In other embodiments, the second abutting surface 401 of the second housing 400 may also be in contact with the first blocking block 13 when the electronic device 1000 is in the flattened state.

[0184] When the electronic device 1000 is in the folded state, the second abutting surface 401 of the second housing 400 contacts the first blocking block 13. Thus, when the electronic device 1000 is impacted, the first blocking block 13 can support the second housing 400, thereby preventing the second housing 400 from dragging the second connecting component 3 toward the main shaft 1 and thereby preventing the screen space 100a enclosed by the first connecting component 2, the second connecting component 3, and the main shaft 1 from shrinking.

[0185] It is understandable that the structure of the second housing 400 and the configuration of the second abutting surface 401 of the second housing 400 can refer to the structure of the first housing 300 and the configuration of the first abutting surface 301 of the first housing 300. Detailed description is omitted here.

[0186] FIG23 is an enlarged view of an embodiment of the electronic device 1000 shown in FIG1 at position H;

[0187] As shown in Figure 23, when the electronic device 1000 is in the flattened state, a portion of the first housing 300 is located on the side of the plate portion of the first shielding block 13, away from the protrusion 133 of the first shielding block 13. This prevents the first shielding block 13 from tipping over in a direction away from the second display area 202 (i.e., in the negative direction of the Y axis) when an impact occurs. In other words, when an impact occurs, a portion of the first housing 300 can support the first shielding block 13 in the positive direction of the Y axis. This improves the reliability of the folding mechanism 100 and the reliability of the electronic device 1000.

[0188] Illustratively, when the electronic device 1000 is in the flat state, a portion of the first side plate portion 303 of the first housing 300 is located on a side of the plate portion of the first blocking block 13 away from the protrusion 133 of the first blocking block 13 .

[0189] As shown in Figure 23, when the electronic device 1000 is in the flattened state, a portion of the second housing 400 is located on the side of the plate portion 131 of the first shielding block 13 that is away from the protrusion 133 of the first shielding block 13. This makes it less likely that the first shielding block 13 will fall away from the second display area 202 (i.e., in the negative direction of the Y axis) when an impact occurs. This improves the reliability of the folding mechanism 100 and the reliability of the electronic device 1000.

[0190] Illustratively, when the electronic device 1000 is in the flattened state, the first side plate portion 403 of the second housing 400 is located on a side of the plate portion 131 of the first blocking block 13 away from the protrusion 133 of the first blocking block 13 .

[0191] 20 , the arrangement between the second blocking block 14 and the first and second housings 300 and 400 can refer to the arrangement between the first blocking block 13 and the first and second housings 300 and 400. Detailed description is omitted here.

[0192] It will be appreciated that the above description illustrates several embodiments of the connection relationship between the main shaft 1 and the first housing 300 and the second housing 400, as well as the positional relationship between the main shaft 1 and the first housing 300 and the second housing 400. In other embodiments, the connection relationship between the main shaft 1 and the first housing 300 and the second housing 400, as well as the positional relationship between the main shaft 1 and the first housing 300 and the second housing 400, are not specifically limited.
