Description

Technical Field

[0001] The present application relates to the technical field of foldable electronic device frames, and particularly to a synchronization component and a foldable electronic device. Background Art

[0002] A foldable electronic device is an electronic device that can fold its screen or body, and has advantages such as portability, flexibility, and versatility, and is widely used in fields such as mobile phones, tablet computers, and laptop computers. One of the core components of a foldable electronic device is a hinge mechanism, which can realize the unfolding and folding of the device while ensuring the stability and durability of the device. The hinge mechanism generally includes an axle cap base component, a swing arm component, and a synchronization component, etc. The synchronization component includes a wedge block, and the wedge block is a mechanism connecting the rotating shaft and the middle frame, which can make the middle frame rotate together with the swing arm of the rotating shaft. The wedge block is connected to the swing arms of at least two swing arm components to achieve synchronization.

[0003] However, there are some problems with the existing synchronization components. When the wedge block is too long, it is easy to have problems that the flatness and straightness do not meet the requirements, resulting in an increase in unqualified products, and the shape error leads to a reduction in the qualification rate; when there are too many wedge blocks, it is easy to have problems that the rotation and stop positions are inconsistent, and the synchronization error leads to too large a closing gap or deformation of the middle frame, and it will also cause uneven flattening angles of the entire device.

[0004] In summary, the setting method of the wedge block causes problems such as shape deviation, synchronization deviation, closing gap, deformation problems, and uneven flattening angles, affecting the quality and performance of the foldable electronic device. Summary of the Invention

[0005] The present application provides a synchronization component and a foldable electronic device, and this synchronization component is used to ensure the swing synchronization of multiple swing arms of the foldable electronic device.

[0006] To achieve the above object, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, a synchronization component is provided. The synchronization component is applied to a foldable electronic device. The foldable electronic device includes two frames and a hinge mechanism connected between the two frames. The hinge mechanism includes an axle cap base component and a swing arm component. The swing arm component includes a plurality of swing arms arranged on the same side of the axle cap base component. The first end of the swing arm is connected to the axle cap base component. The synchronization component includes: a plurality of synchronizing members, the plurality of synchronizing members extend along the length direction of the folding axis of the foldable electronic device, the synchronizing members are installed on the frame, each synchronizing member is connected to the second ends of at least two adjacent swing arms, a first synchronization structure is arranged at one end of the synchronizing member, and a second synchronization structure is arranged at the second end of the synchronizing member. Adjacent two synchronizing members are synchronized through the cooperation of the first synchronization structure and the second synchronization structure.

[0008] The synchronization component provided by the embodiment of the present application can achieve the synchronous linkage of multiple synchronizing parts through the cooperation of the first synchronization structure and the second synchronization structure, avoiding inconsistent rotation and synchronization errors that may cause too large a closing gap or deformation of the middle frame, resulting in uneven flattening angles of the entire device. Moreover, through the docking of the first synchronization structure and the second synchronization structure, synchronization can be achieved without machining very long synchronizing parts, avoiding problems such as large machining difficulty for long synchronizing parts, easy non-compliance with flatness and straightness requirements, resulting in an increase in defective products, and shape errors leading to a decrease in the qualification rate.

[0009] In one embodiment, the first synchronization structure is provided on the end wall of the first end of the synchronizing part, and the second synchronization structure is provided on the end wall of the second end of the synchronizing part. When the first synchronization structure and the second synchronization structure are docked, the end wall of the first end of the synchronizing part and the end wall of the second end of the synchronizing part are abutted and fitted to each other. By arranging the first synchronization structure and the second synchronization structure on the end walls of the synchronizing part, close docking between the synchronizing parts is achieved, making the connection between the synchronizing parts more stable and firm, and improving the strength and durability of the synchronization component.

[0010] In one embodiment, one of the first synchronization structure and the second synchronization structure is a docking protrusion, and the other is a docking hole. The docking protrusion is adapted to the docking hole and is inserted into the docking hole. By setting one of the first synchronization structure and the second synchronization structure as a docking protrusion and the other as a docking hole, a simple and effective docking method between the synchronizing parts is achieved, making the connection between the synchronizing parts more convenient and fast, and improving the installation and disassembly efficiency of the synchronization component.

[0011] In one embodiment, the synchronization component further includes a connection mechanism. The connection mechanism is connected between two adjacent synchronizing parts. First connection structures are provided on both sides of the connection mechanism, and second connection structures are provided at both the first end and the second end of the synchronizing part. The synchronizing part and the connection mechanism are connected through the first connection structure and the second connection structure. By setting the first connection structure and the second connection structure, stable cooperation between the synchronizing part and the connection mechanism is achieved, making the structure of the synchronization component more compact and firm, and improving the strength and durability of the synchronization component.

[0012] In one embodiment, one of the first connection structure and the second connection structure is a sliding groove, and the other is a sliding block. The sliding groove and the sliding block both extend along the length direction perpendicular to the hinge mechanism, and the sliding groove is installed in the sliding block. By setting one of the first connection structure and the second connection structure as a sliding groove and the other as a sliding block, a simple and effective connection method between the synchronizing part and the connection mechanism is achieved, making the connection between the synchronizing part and the connection mechanism more convenient and fast, and improving the installation and disassembly efficiency of the synchronization component.

[0013] In one embodiment, a sliding groove is provided on the side wall of the end of the synchronizing member. The connecting mechanism includes a body in which a receiving groove is provided. The end of the synchronizing member is inserted into the receiving groove. A slider is provided on the inner side wall of the end of the body corresponding to the synchronizing member. The ends of both synchronizing members are inserted into the receiving groove. By providing the sliding groove on the side wall of the end of the synchronizing member, a lateral connection between the synchronizing member and the connecting mechanism is achieved, making the structure of the synchronization assembly more compact and simplified.

[0014] In one embodiment, sliding grooves are provided on the side walls on both sides of the end of the synchronizing member, and sliders are provided on the two inner side walls of the end of the body corresponding to the synchronizing member. By providing sliding grooves on the side walls on both sides of the end of the synchronizing member, a two-way connection between the synchronizing member and the connecting mechanism is achieved, making the structure of the synchronization assembly more symmetrical and balanced, and improving the stability and reliability of the synchronization assembly.

[0015] In one embodiment, the receiving groove forms a first opening on the side of the body away from the shaft cover base assembly, and the receiving groove forms second openings at both ends in the direction parallel to the folding shaft of the body. The end of the synchronizing member enters the receiving groove through the first opening, and the end of the synchronizing member is given way through the second opening. By providing the receiving groove with a first opening on the side of the body away from the shaft cover base assembly, a convenient connection between the synchronizing member and the connecting mechanism is achieved, making the installation and disassembly of the synchronization assembly more convenient and fast, and improving the use efficiency of the synchronization assembly.

[0016] In one embodiment, a relief groove is provided on the side wall of the body. The relief groove forms a third opening on the side of the side wall of the body away from the shaft cover base assembly. The relief groove is connected to the receiving groove and the first opening. A through hole is provided at the end of the synchronizing member, and a flange extending circumferentially along the through hole is provided on the side wall of the end. The flange is installed in the relief groove through the third opening. The through hole at the end of the synchronizing member is for facilitating the insertion of a screw to connect the connecting mechanism to the middle frame, thereby enhancing the connection strength between the synchronization assembly and the middle frame and improving the durability of the synchronization assembly.

[0017] In one embodiment, the through hole is a circular hole, the bottom of the relief groove is a semi-circular groove, and the radius of the semi-circular groove is the same as the radius of the outer wall of the flange. By providing the through hole as a circular hole, the bottom of the relief groove as a semi-circular groove, and the radius of the semi-circular groove being the same as the radius of the outer wall of the flange, a tight fit between the synchronizing member and the connecting mechanism is achieved, making the structure of the synchronization assembly more stable and firm.

[0018] In one embodiment, the inner side of the shaft cover base assembly has a first end face and a mounting groove formed in the first end face. The mounting groove extends along the length direction of the shaft cover base assembly, and forms two opposite side walls and a bottom wall between the two side walls on the inner side of the shaft cover base assembly. The side walls on the inner side of the shaft cover base assembly are folding limiting surfaces, and the first end face is an unfolding limiting surface. The connecting mechanism further includes a limiting structure. The limiting structure is arranged at one end of the body close to the shaft cover base assembly, and a limiting surface is arranged on the limiting structure. The limiting surface has a first limiting position blocked by the inner end face of the shaft cover base assembly and a second limiting position blocked by the first end face. When the folding electronic device is in the folded state, the limiting surface is in the first limiting position. When the folding electronic device is in the unfolded state, the limiting surface is in the second limiting position. This improves the unity of the stop position and makes the flattening angles at different axial positions the same.

[0019] In one embodiment, at least one groove side wall of the sliding groove is in interference fit with the sliding block. By setting at least one groove side wall of the sliding groove to be in interference fit with the sliding block, the tight fixation between the sliding block and the sliding groove is realized, making the structure of the synchronization component more stable and firm.

[0020] The second aspect of the present application provides a folding electronic device. The folding electronic device includes two frames and a hinge mechanism connected between the two frames. The hinge mechanism includes a shaft cover base assembly, a swing arm assembly and a synchronization component. The swing arm assembly includes a plurality of swing arms. The first end of the swing arm is connected to the shaft cover base assembly. Among them, the folding electronic device includes the above-mentioned synchronization component.

[0021] Through the above technical solution, since the electronic device includes the above-mentioned synchronization component, it at least has all the beneficial effects of the synchronization component, which will not be elaborated here. Description of the Drawings

Exactly, the use of words such as "in one embodiment", "exemplarily", "for example" is intended to present relevant concepts in a specific manner.

[0045] In order to make the objectives, technical solutions, and advantages of this application clearer and more understandable, the following further elaborates on this application in conjunction with the accompanying drawings and embodiments.

[0046] A foldable electronic device is an electronic device capable of folding the screen or the body, with advantages such as portability, flexibility, and versatility, and is widely used in fields such as mobile phones, tablet computers, and laptop computers. One of the core components of a foldable electronic device is the hinge mechanism, which can achieve the unfolding and folding of the device while ensuring the stability and durability of the device. The hinge mechanism generally includes an axle cover base assembly, a swing arm assembly, and a synchronization assembly, etc. The synchronization assembly includes a wedge block, which is a mechanism connecting the rotating shaft and the middle frame, and can make the middle frame rotate together with the swing arm of the rotating shaft. The wedge block is connected to the swing arms of at least two swing arm assemblies to achieve synchronization.

[0047] However, there are some problems with the existing synchronization components. When the wedge block is too long, it is prone to non-compliance with the requirements of flatness and straightness, resulting in an increase in defective products and a reduction in the qualification rate due to shape errors; when there are too many wedge blocks, it is prone to inconsistent rotation and positioning, and synchronization errors lead to too large a closing gap or deformation of the middle frame, and it will also cause uneven flattening angles of the entire device.

[0048] In summary, the setting method of the wedge block leads to problems such as shape deviation, synchronization deviation, closing gap, deformation problems, and uneven flattening angles, affecting the quality and performance of the foldable electronic device. Currently, generally by increasing the stiffness of the middle frame or strictly controlling the flatness of the wedge block, this problem is weakened, but this will lead to limited materials for the middle frame, affecting the experience such as the weight of the whole machine. In addition, the yield rate of single parts decreases, the cost increases, resulting in a decline in the competitiveness of the whole machine.

[0049] Specifically, shape deviation will affect the fitting accuracy and motion effect of the synchronization parts, synchronization deviation will affect the consistency of the rotation and positioning of the middle frame, closing gap and deformation problems will affect the appearance and texture of the middle frame, and uneven flattening angle problems will affect the use performance and user experience of the device.

[0050] Specifically, please refer to Figures 1 to 11As shown in the figure, the synchronization component of the embodiment of the present application is used for a foldable electronic device. The foldable electronic device includes two frames 1 and a hinge mechanism 2 connected between the two frames 1. The hinge mechanism 2 includes an axle cover base component 10 and a swing arm component 20. The swing arm component 20 includes a plurality of swing arms 21 arranged on the same side of the axle cover base component 10. The first end of the swing arm 21 is connected to the axle cover base component 10. The synchronization component includes: a plurality of synchronizers 31. The plurality of synchronizers 31 extend along the length direction of the folding axis of the foldable electronic device. The synchronizer 31 is installed on the frame 1. Each synchronizer 31 is connected to the second ends of at least two adjacent swing arms 21. A first synchronization structure 311 is provided at one end of the synchronizer 31, and a second synchronization structure 312 is provided at the second end of the synchronizer 31. The adjacent two synchronizers 31 are synchronized through the cooperation of the first synchronization structure 311 and the second synchronization structure 312. It should be noted that a foldable electronic device is an electronic device that can realize the folding of the screen or the body, and has the advantages of portability, flexibility, and versatility, and is widely used in the fields of mobile phones, tablet computers, laptop computers, etc. The frame 1 is one of the components of the foldable electronic device, and is a structure for fixing and protecting the screen or the body. There are usually two, located on both sides of the device respectively, and can be connected together through the hinge mechanism 2 to realize the unfolding and folding of the device. The hinge mechanism 2 is one of the components of the foldable electronic device, and is a mechanism for connecting and rotating the two frames 1, and usually includes an axle cover base component 10, a swing arm component 20, etc. The axle cover base component 10 is one of the components of the hinge mechanism 2, and is a structure for fixing and supporting the rotating shaft, and usually includes a base and an axle cover located outside the base. The swing arm component 20 is one of the components of the hinge mechanism 2, and is a structure for realizing the unfolding and folding of the device, and usually includes a plurality of swing arms 21. The first end of each swing arm 21 is connected to the axle cover base component 10, and the second end is connected to the synchronization component to realize the rotation and synchronization of the device.

[0051] Through the coordinated synchronization of the first synchronization structure 311 and the second synchronization structure 312, the synchronized linkage of multiple synchronizing members 31 can be achieved, avoiding inconsistent rotation and the problem that the closing gap of the middle frame is too large or deformed due to synchronization error, resulting in uneven flattening angles of the entire device. Specifically, when the foldable electronic device transitions from the unfolded state to the folded state, since one end of the synchronizing member 31 is provided with the first synchronization structure 311 and the other end is provided with the second synchronization structure 312, adjacent synchronizing members 31 are synchronized through the cooperation of the first synchronization structure 311 and the second synchronization structure 312, ensuring the relative position and angle between the synchronizing member 31 and the swing arm 21, and avoiding synchronization error and inconsistent rotation. When the foldable electronic device transitions from the folded state to the unfolded state, the same principle applies. Therefore, through the docking of the first synchronization structure 311 and the second synchronization structure 312, the synchronized linkage of multiple synchronizing members 31 can be achieved, enabling the two frames 1 to be smoothly unfolded and folded, improving the service life and reliability of the device.

[0052] Through the docking of the first synchronization structure 311 and the second synchronization structure 312, synchronization can be achieved without machining very long synchronizing members 31, avoiding the problems of overly long synchronizing members 31, difficult machining, easy non-compliance with flatness and straightness requirements, resulting in an increase in defective products, and shape error leading to a reduction in the qualified rate. Specifically, since one end of the synchronizing member 31 is provided with the first synchronization structure 311 and the other end is provided with the second synchronization structure 312, adjacent synchronizing members 31 are synchronized through the cooperation of the first synchronization structure 311 and the second synchronization structure 312, forming a structure similar to a continuous chain between the synchronizing members 31. In this way, the length of the synchronizing member 31 does not need to cover the entire length of the hinge mechanism 2, but only needs to cover part of the length of the hinge mechanism 2, thereby reducing the length of the synchronizing member 31 and lowering the machining difficulty and cost. Compared with the prior art, it can not only reduce the requirements for the stiffness of the middle frame, expand the material usage range, but also ensure the overall machine gap of the whole machine while relaxing the flatness of the wedge block.

[0053] See Figures 5 to 8As shown, the first synchronization structure 311 in the embodiment of the present application is disposed on the end wall of the first end of the synchronizer 31, and the second synchronization structure 312 is disposed on the end wall of the second end of the synchronizer 31. When the first synchronization structure 311 and the second synchronization structure 312 are docked, the end wall of the first end of the synchronizer 31 and the end wall of the second end of the synchronizer 31 are abutted and fitted against each other. By disposing the first synchronization structure 311 and the second synchronization structure 312 on the end wall of the synchronizer 31, a tight docking between the synchronizers 31 is achieved, making the connection between the synchronizers 31 more stable and firm, and improving the strength and durability of the synchronization assembly. Specifically, when two adjacent synchronizers 31 are synchronized through the cooperation of the first synchronization structure 311 and the second synchronization structure 312, the first synchronization structure 311 and the second synchronization structure 312 on the end wall of the synchronizer 31 will be docked with each other, thereby forming a firm connection point. In this way, there will be no loosening or detachment between the synchronizers 31, nor will the phase between the synchronizers 31 change due to external force or vibration, thus ensuring the stability and reliability of the synchronization assembly. By making the end wall of the first end of the synchronizer 31 and the end wall of the second end of the synchronizer 31 abut and fit against each other, the flatness and straightness between the synchronizers 31 are ensured, avoiding the shape error between the synchronizers 31, and improving the accuracy and consistency of the synchronization assembly. Specifically, when two adjacent synchronizers 31 are synchronized through the cooperation of the first synchronization structure 311 and the second synchronization structure 312, the first synchronization structure 311 and the second synchronization structure 312 on the end wall of the synchronizer 31 will not only be docked with each other, but also make the end walls of the synchronizer 31 abut and fit against each other, thereby forming a flat connection surface.

[0054] See Figures 5 to 8 As shown, one of the first synchronization structure 311 and the second synchronization structure 312 in the embodiment of the present application is a docking convex portion, and the other is a docking hole. The docking convex portion is adapted to the docking hole and is inserted into the docking hole. By setting one of the first synchronization structure 311 and the second synchronization structure 312 as the docking convex portion and the other as the docking hole, a simple and effective docking method between the synchronizers 31 is achieved, making the connection between the synchronizers 31 more convenient and fast, and improving the installation and disassembly efficiency of the synchronization assembly. Specifically, when two adjacent synchronizers 31 are synchronized through the cooperation of the first synchronization structure 311 and the second synchronization structure 312, the docking convex portion on the end wall of the synchronizer 31 will be inserted into the docking hole on the end wall of another synchronizer 31, thereby forming a firm connection point. In this way, no additional screws or other fixing parts are required between the synchronizers 31, nor are complex processing techniques required. Only simple plugging and unplugging operations are needed to achieve the connection and separation between the synchronizers 31, reducing the manufacturing and maintenance costs of the synchronization assembly.

[0055] In other embodiments of the present application, there are multiple docking protrusions and multiple docking holes. The multiple docking protrusions and the multiple docking holes are in one-to-one correspondence and cooperation. On the one hand, through the combined cooperation of the multiple docking protrusions and the multiple docking holes, the connection strength between the two synchronizing members is improved. On the other hand, the cooperation of the multiple docking protrusions and the multiple docking holes can limit the relative rotation between the two synchronizing members and ensure synchronism.

[0056] See Figures 1 to 4 As shown, the synchronizing assembly in the embodiment of the present application further includes a connecting mechanism 32. The connecting mechanism 32 is connected between two adjacent synchronizing members 31. First connecting structures are provided on both sides of the connecting mechanism 32, and second connecting structures are provided at the first end and the second end of the synchronizing member 31. The synchronizing member 31 and the connecting mechanism 32 are connected through the first connecting structure and the second connecting structure. By providing the first connecting structure and the second connecting structure, stable cooperation between the synchronizing member 31 and the connecting mechanism 32 is achieved, making the structure of the synchronizing assembly more compact and firm, and improving the strength and durability of the synchronizing assembly. Specifically, first connecting structures are provided on both sides of the connecting mechanism 32, second connecting structures are provided at the first end and the second end of the synchronizing member 31, and the synchronizing member 31 and the connecting mechanism 32 are connected through the first connecting structure and the second connecting structure. The first connecting structure and the second connecting structure can achieve tight cooperation between the synchronizing member 31 and the connecting mechanism 32, avoiding loosening or falling off between the synchronizing member 31 and the connecting mechanism 32.

[0057] By connecting the synchronizing member 31 and the connecting mechanism 32 through the first connecting structure and the second connecting structure, the relative position and angle between the synchronizing members 31 are ensured, avoiding synchronization errors and rotational inconsistencies between the synchronizing members 31, and improving the accuracy and consistency of the synchronizing assembly. Specifically, when two adjacent synchronizing members 31 are synchronized through the cooperation of the first synchronizing structure 311 and the second synchronizing structure 312, the synchronizing member 31 and the connecting mechanism 32 are connected through the first connecting structure and the second connecting structure, thus ensuring the relative position and angle between the synchronizing members 31 and making the synchronizing members 31 form a structure similar to a continuous chain. In this way, there will be no synchronization errors or rotational inconsistencies between the synchronizing members 31, and the phase between the synchronizing members 31 will not change due to external forces or vibrations, thus ensuring the accuracy and consistency of the synchronizing assembly. In addition, by providing the connecting mechanism 32, detachable connection between the synchronizing members 31 is achieved, making the installation and maintenance of the synchronizing assembly more convenient and flexible, and improving the service efficiency and life of the synchronizing assembly. Specifically, when it is necessary to replace or repair a certain synchronizing member 31, only the connecting mechanism 32 needs to be disassembled, and the synchronizing member 31 can be separated from the synchronizing assembly for replacement.

[0058] See Figures 5 to 10As shown, one of the first connection structure and the second connection structure in the embodiments of the present application is a chute 313, and the other is a slider 3212. The chute 313 and the slider 3212 both extend along the length direction perpendicular to the hinge mechanism, and the chute 313 is installed inside the slider 3212. By setting one of the first connection structure and the second connection structure as the chute 313 and the other as the slider 3212, a simple and effective connection method between the synchronizer 31 and the connection mechanism 32 is achieved, making the connection between the synchronizer 31 and the connection mechanism 32 more convenient and fast, and improving the installation and disassembly efficiency of the synchronization assembly. Specifically, when two adjacent synchronizers 31 are synchronized through the cooperation of the first synchronization structure 311 and the second synchronization structure 312, the synchronizer 31 and the connection mechanism 32 are connected through the first connection structure and the second connection structure. The chute 313 on the end wall of one of the synchronizers 31 will be inserted into the sliders 3212 on both sides of the connection mechanism 32, thereby forming a firm connection point. In this way, no additional screws or other fixing parts are required between the synchronizer 31 and the connection mechanism 32, nor complex processing techniques. Only simple plugging and unplugging operations are needed to achieve the connection and separation between the synchronizer 31 and the connection mechanism 32, reducing the manufacturing and maintenance costs of the synchronization assembly.

[0059] In addition, by installing the chute 313 inside the slider 3212, a tight fit between the synchronizer 31 and the connection mechanism 32 is achieved, making the structure of the synchronization assembly more stable and firm, and improving the strength and durability of the synchronization assembly. Specifically, when two adjacent synchronizers 31 are synchronized through the cooperation of the first synchronization structure 311 and the second synchronization structure 312, the synchronizer 31 and the connection mechanism 32 are connected through the first connection structure and the second connection structure. The chute 313 on the end wall of one of the synchronizers 31 will be inserted into the sliders 3212 on both sides of the connection mechanism 32, thereby forming a tight connection point. In this way, there will be no loosening or falling off between the synchronizer 31 and the connection mechanism 32, nor will the phase between the synchronizer 31 and the connection mechanism 32 change due to external forces or vibrations, thus ensuring the stability and reliability of the synchronization assembly.

[0060] See Figures 5 to 10As shown, the sliding groove 313 in the embodiment of the present application is provided on the side wall of the end of the synchronization member 31. The connecting mechanism 32 includes a body 321. An accommodation groove 3211 is provided inside the body 321. The end of the synchronization member 31 is inserted into the accommodation groove 3211. A slider 3212 is provided on the inner side wall of the end of the body 321 corresponding to the synchronization member 31. The ends of the two synchronization members 31 are both inserted into the accommodation groove 3211. By providing the sliding groove 313 on the side wall of the end of the synchronization member 31, the lateral connection between the synchronization member 31 and the connecting mechanism 32 is realized, making the structure of the synchronization assembly more compact and simplified, and improving the space utilization rate and aesthetics of the synchronization assembly. Specifically, when two adjacent synchronization members 31 are synchronized through the cooperation of the first synchronization structure 311 and the second synchronization structure 312, the synchronization member 31 and the connecting mechanism 32 are connected through the first connection structure and the second connection structure. The sliding groove 313 on the end wall of one of the synchronization members 31 will be inserted into the sliders 3212 on both sides of the connecting mechanism 32, thereby forming a firm connection point. In this way, the connection between the synchronization member 31 and the connecting mechanism 32 does not need to extend along the length direction of the hinge mechanism, but only needs to extend along the direction perpendicular to the length direction of the hinge mechanism, thereby reducing the length of the synchronization assembly and reducing the occupied space of the synchronization assembly. By providing the body 321 and the accommodation groove 3211 of the connecting mechanism 32, the embedded connection between the synchronization member 31 and the connecting mechanism 32 is realized, making the structure of the synchronization assembly more stable and firm. Specifically, an accommodation groove 3211 is provided inside the body 321 of the connecting mechanism 32. The end of the synchronization member 31 is inserted into the accommodation groove 3211. A slider 3212 is provided on the inner side wall of the end of the body 321 corresponding to the synchronization member 31. The ends of the two synchronization members 31 are both inserted into the accommodation groove 3211. In this way, the connection between the synchronization member 31 and the connecting mechanism 32 is not a simple surface contact, but a deep embedded connection, thereby increasing the contact area between the synchronization member 31 and the connecting mechanism 32, enhancing the bonding force between the synchronization member 31 and the connecting mechanism 32, and ensuring the straightness and flatness between multiple synchronization members 31.

[0061] See Figures 5 to 10As shown in the figure, sliding grooves 313 are provided on the side walls on both sides of the end of the synchronizing member 31 in the embodiment of the present application, and sliding blocks 3212 are provided on the two inner side walls of the end of the main body 321 corresponding to the synchronizing member 31. By providing sliding grooves 313 on the side walls on both sides of the end of the synchronizing member 31, a two-way connection between the synchronizing member 31 and the connecting mechanism 32 is realized, making the structure of the synchronizing assembly more symmetrical and balanced, and improving the stability and reliability of the synchronizing assembly. Specifically, when two adjacent synchronizing members 31 are synchronized through the cooperation of the first synchronizing structure 311 and the second synchronizing structure 312, the synchronizing member 31 and the connecting mechanism 32 are connected through the first connecting structure and the second connecting structure. The sliding groove 313 on the end wall of one of the synchronizing members 31 will be inserted into the sliding blocks 3212 on both sides of the connecting mechanism 32, thus forming a firm connection point. Since sliding grooves 313 are provided on the side walls on both sides of the end of the synchronizing member 31, the connection between the synchronizing member 31 and the connecting mechanism 32 has the characteristic of left-right symmetry, making the structure of the synchronizing assembly more uniform and balanced, avoiding skewing or tilting of the structure of the synchronizing assembly, and improving the stability and reliability of the structure of the synchronizing assembly.

[0062] By providing sliding blocks 3212 on the two inner side walls of the end of the main body 321 corresponding to the synchronizing member 31, a double cooperation between the synchronizing member 31 and the connecting mechanism 32 is realized, making the structure of the synchronizing assembly more compact and firm, and improving the strength and durability of the synchronizing assembly. The connection between the synchronizing member 31 and the connecting mechanism 32 is not a simple surface contact, but a deep embedded connection, thereby increasing the contact area between the synchronizing member 31 and the connecting mechanism 32, enhancing the binding force between the synchronizing member 31 and the connecting mechanism 32, and improving the stability and firmness of the structure of the synchronizing assembly. Since sliding blocks 3212 are provided on the two inner side walls of the end of the main body 321 corresponding to the synchronizing member 31, the connection between the synchronizing member 31 and the connecting mechanism 32 has the characteristic of up-down symmetry, making the structure of the synchronizing assembly more uniform and balanced, avoiding skewing or tilting of the structure of the synchronizing assembly, and improving the stability and reliability of the structure of the synchronizing assembly.

[0063] See Figure 9 and Figure 10As shown in the figure, the receiving groove 3211 in the embodiment of the present application forms a first opening 3213 on the side of the body 321 away from the shaft cover base assembly 10. The receiving groove 3211 forms second openings 3214 at both ends in the direction parallel to the folding axis on the body 321. The end of the synchronizing member 31 enters the receiving groove 3211 through the first opening 3213, and the end of the synchronizing member 31 is given way through the second opening 3214. By providing that the receiving groove 3211 forms a first opening 3213 on the side of the body 321 away from the shaft cover base assembly 10, a convenient connection between the synchronizing member 31 and the connecting mechanism 32 is realized, making the installation and disassembly of the synchronizing assembly more convenient and fast, and improving the use efficiency of the synchronizing assembly. Specifically, when installing or disassembling the synchronizing member 31, only the end of the synchronizing member 31 needs to be inserted into or taken out of the receiving groove 3211 through the first opening 3213, without disassembling or installing other components, thus simplifying the installation and disassembly process of the synchronizing assembly, saving time and cost, and improving the use efficiency of the synchronizing assembly. By providing that the receiving groove 3211 forms second openings 3214 at both ends in the direction parallel to the folding axis on the body 321, flexible yielding between the synchronizing member 31 and the connecting mechanism 32 is realized.

[0064] See Figures 3 to 10 As shown in the figure, a yielding groove 3215 is provided on the side wall of the body 321 in the embodiment of the present application. The yielding groove 3215 forms a third opening 32151 on the side of the side wall of the body 321 away from the shaft cover base assembly 10. The yielding groove 3215 is communicated with the receiving groove 3211 and the first opening 3213. A through hole 314 is provided at the end of the synchronizing member 31, and a flange 315 extending circumferentially along the through hole 314 is provided on the side wall of the end. The flange 315 is installed in the yielding groove 3215 from the third opening 32151. The through hole 314 at the end of the synchronizing member 31 is for facilitating the passing of screws to connect the connecting mechanism 32 and the middle frame through the screws, thereby enhancing the connection strength between the synchronizing assembly and the middle frame and improving the durability of the synchronizing assembly. Specifically, the through hole 314 at the end of the synchronizing member 31 corresponds to the corresponding hole on the middle frame. The screw passes through the through hole 314 at the end of the synchronizing member 31 and the corresponding hole on the middle frame, and then the nut is tightened, so that the end of the synchronizing member 31 is firmly connected to the middle frame, thus avoiding loosening or falling off of the end of the synchronizing member 31 when subjected to external force or vibration. The flange 315 at the end of the synchronizing member 31 is to prevent the end of the synchronizing member 31 from moving excessively in the receiving groove 3211, thus ensuring the correct cooperation between the end of the synchronizing member 31 and the yielding groove 3215. By providing the through hole 314 and the flange 315 at the end of the synchronizing member 31, axial fixation between the synchronizing member 31 and the connecting mechanism 32 can be further realized.

[0065] See Figures 3 to 10As shown, the through hole 314 in the embodiment of the present application is a circular hole, the bottom of the relief groove 3215 is a semi-circular groove, and the radius of the semi-circular groove is the same as the radius of the outer wall of the flange 315. By setting the through hole 314 as a circular hole, the bottom of the relief groove 3215 as a semi-circular groove, and the radius of the semi-circular groove being the same as the radius of the outer wall of the flange 315, a tight fit between the synchronizer 31 and the connecting mechanism 32 is achieved, making the structure of the synchronizing assembly more stable and firm. Specifically, the end of the synchronizer 31 is inserted into the receiving groove 3211, and a slider 3212 is provided on the inner side wall of the corresponding end of the main body 321 to the synchronizer 31. The ends of the two synchronizers 31 are both inserted into the receiving groove 3211. In this way, the connection between the synchronizer 31 and the connecting mechanism 32 is not a simple surface contact, but a deep embedded connection, thereby increasing the contact area between the synchronizer 31 and the connecting mechanism 32 and enhancing the bonding force between the synchronizer 31 and the connecting mechanism 32. At the same time, since the through hole 314 is a circular hole, the bottom of the relief groove 3215 is a semi-circular groove, and the radius of the semi-circular groove is the same as the radius of the outer wall of the flange 315, the end of the synchronizer 31 can form a tight fit with the inner wall of the relief groove 3215, thus preventing the end of the synchronizer 31 from loosening or shaking in the receiving groove 3211.

[0066] See Figures 1 to 4 and Figure 11As shown, the inner side of the shaft cover base assembly 10 in the embodiment of the present application has a first end face and a mounting groove 11 opened on the first end face. The mounting groove 11 extends along the length direction of the shaft cover base assembly 10, and forms two opposite side walls and a bottom wall located between the two side walls on the inner side of the shaft cover base assembly. The side walls on the inner side of the shaft cover base assembly 10 are folding limiting surfaces 13, and the first end face is an unfolding limiting surface 12. The connecting mechanism 32 further includes a limiting structure 322. The limiting structure 322 is arranged at one end of the body 321 close to the shaft cover base assembly 10. A limiting surface 3221 is arranged on the limiting structure 322. The limiting surface 3221 has a first limiting position blocked by the inner end face of the shaft cover base assembly 10 and a second limiting position blocked by the first end face. When the foldable electronic device is in the folded state, the limiting surface 3221 is in the first limiting position. When the foldable electronic device is in the unfolded state, the limiting surface 3221 is in the second limiting position. By setting the side walls on the inner side of the shaft cover base assembly 10 as the folding limiting surfaces 13 and the first end face as the unfolding limiting surface 12, the angle limitation between the connecting mechanism 32 and the shaft cover base assembly 10 is realized. Specifically, when the synchronous assembly changes from the unfolded state to the folded state, the limiting surface 3221 of the connecting mechanism 32 will contact the inner end face of the shaft cover base assembly 10, thereby limiting the folding angle of the connecting mechanism 32 and preventing the connecting mechanism 32 from being over-folded. When the synchronous assembly changes from the folded state to the unfolded state, the limiting surface 3221 of the connecting mechanism 32 will contact the first end face of the shaft cover base assembly 10, thereby limiting the unfolding angle of the connecting mechanism 32 and preventing the connecting mechanism 32 from being over-unfolded and affecting the normal change of the structure of the synchronous assembly. Therefore, by setting the side walls on the inner side of the shaft cover base assembly 10 as the folding limiting surfaces 13 and the first end face as the unfolding limiting surface 12, the angle limitation between the connecting mechanism 32 and the shaft cover base assembly 10 can be realized. It breaks the traditional limitation of placing the stop on the middle frame and the swing arm 21, improves the unity of the stop, and makes the flattening angles at different positions in the axial direction the same.

[0067] At least one groove side wall of the sliding groove 313 in the embodiment of the present application is in interference fit with the sliding block 3212. By setting at least one groove side wall of the sliding groove 313 to be in interference fit with the sliding block 3212, a tight fixation between the sliding block 3212 and the sliding groove 313 is achieved, making the structure of the synchronization component more stable and firm. Specifically, the external dimension of the sliding block 3212 is slightly larger than the internal dimension of the sliding groove 313. When the sliding block 3212 is inserted into the sliding groove 313, at least one side surface of the sliding block 3212 will elastically deform with at least one groove side wall of the sliding groove 313, thereby generating a restoring force, so that a tight interference fit is formed between the sliding block 3212 and the sliding groove 313, thus avoiding loosening or shaking of the sliding block 3212 in the sliding groove 313, ensuring the position of the sliding block 3212 in the sliding groove 313, and improving the stability and firmness of the structure of the synchronization component. And it can ensure the flatness and straightness of the overall synchronization component.
