[0037] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0038] Reference is made below to Figures 1 - 7 describe the connection component of the electronic device according to the embodiments of the present invention.

[0039] As Figure 1 , Figure 6 and Figure 7As shown in the figure, a connection component of an electronic device according to an embodiment of the first aspect of the present invention. The electronic device includes a body, the body includes two sub-bodies and a connection component. The connection component is disposed between the two sub-bodies and connects the two sub-bodies, so that the two sub-bodies can rotate relative to each other. Each sub-body includes a main board 1, and the main board 1 can be a PCB board. The main boards 1 of the two sub-bodies are connected by a flexible circuit board 11, and at least a part of the flexible circuit board 11 corresponds to the connection component. The electronic device can have a folded state and an unfolded state. By the relative rotation of the two sub-bodies, the folding and unfolding of the electronic device can be realized. During the folding and unfolding of the electronic device, the part of the flexible circuit board 11 corresponding to the connection component is deformed under force.

[0040] The connection component includes: a rotational connection mechanism 2 and multiple groups of shaper groups. The two sub-bodies are adapted to be rotationally connected through the rotational connection mechanism 2. The rotation axis of the rotational connection mechanism 2 extends along a first direction (refer to the e1 direction in Figures 1 - 4 ), so that the two sub-bodies can rotate relative to each other, and thus the foldability of the electronic device can be realized through the relative rotation of the two sub-bodies. Optionally, the rotational connection mechanism 2 can be a hinge mechanism.

[0041] Wherein, when the electronic device is in the unfolded state, the two sub-bodies of the electronic device are arranged in a second direction (refer to the e2 direction in Figure 1 , Figure 3 , Figure 6 and Figure 7 ); when the electronic device is in the folded state, the two sub-bodies of the electronic device are stacked in the thickness direction of the sub-body, so that the occupied area of the electronic device can be significantly reduced, which is convenient for carrying the electronic device.

[0042] Optionally, the electronic device can include a flexible display screen 4. The flexible display screen 4 can be disposed on the body. The flexible display screen 4 can be a complete display screen. The flexible display screen 4 simultaneously supports and covers the two sub-bodies and also simultaneously supports and covers the connection component. Since the flexible display screen 4 can be bent, when the body is folded, the flexible display screen 4 can be folded synchronously with the body. Of course, when the body is unfolded, the flexible display screen 4 is unfolded with the body, so that the electronic device with a display function can be folded.

[0043] Optionally, the electronic device can be a foldable mobile terminal. For example, the electronic device can be a foldable mobile phone or a foldable tablet computer.

[0044] A plurality of shaping device groups are used to shape the flexible circuit board 11. The plurality of shaping device groups are arranged on the rotation connection mechanism 2, and the plurality of shaping device groups are arranged at intervals in the second direction. The second direction is perpendicular to the first direction and perpendicular to the thickness direction of the machine body. Each shaping device group includes at least one shaping device 3. For example, each shaping device group may include one shaping device 3; or, some of the shaping device groups include one shaping device 3, and the remaining shaping device groups include a plurality of shaping devices 3; or, each shaping device group includes a plurality of shaping devices 3.

[0045] It should be noted that the "plurality" described in the present invention means two or more, and the "plurality of groups" means two or more groups.

[0046] Wherein, each shaping device 3 is telescopic in the third direction (refer to the e3 direction in Figure 2 , Figure 4 , Figure 6 and Figure 7 ), and the third direction is parallel to the thickness direction of the machine body. By the telescopic movement of the shaping device 3 in the third direction, the length of the shaping device 3 in the third direction can be changed. When the flexible circuit board 11 passes through the connection assembly and cooperates with the connection assembly, the flexible circuit board 11 is adapted to be wound around the free end 321 of the shaping device 3 and between two adjacent shaping device groups. The free end 321 of the shaping device 3 contacts the flexible circuit board 11 and has a supporting effect on the flexible circuit board 11. A plurality of shaping devices 3 form a plurality of support points at different positions, so that a multi-point support can be formed for the flexible circuit board 11, and an auxiliary shaping effect is achieved on the flexible circuit board 11.

[0047] Wherein, the free end 321 of the shaping device 3 is relative to the fixed end of the shaping device 3. The fixed end of the shaping device 3 is connected to the rotation connection mechanism 2 and is relatively fixed. Through the telescopic movement of the shaping device 3, the free end 321 of the shaping device 3 can move in the third direction. In this way, when the flexible circuit board 11 is in different stress states, the flexible circuit board 11 will undergo different deformations. And through the telescopic movement of the shaping device 3, the length of the shaping device 3 in the third direction is adaptively adjusted, thereby adjusting the position of the free end 321 of the shaping device 3, so that the free end 321 of the shaping device 3 moves to adapt to different deformations of the flexible circuit board 11. In this way, it can be ensured that the free end 321 of the shaping device 3 always contacts the flexible circuit board 11, which has a good supporting effect on the flexible circuit board 11 and enables the flexible circuit board 11 to be shaped into a set shape.

[0048] For example, when the flexible circuit board 11 is pulled on both sides in the second direction, the flexible circuit board 11 is in a stretched state at this time. Through the expansion and contraction of the shaper 3, a buffering effect can be achieved, and it can avoid excessive deformation and damage caused by dead fold points in the Z-shaped flexible circuit board in the related art; when the flexible circuit board 11 contracts toward the middle in the second direction, the flexible circuit board 11 is in a compressed state at this time, and the shaper 3 can help the flexible circuit board 11 rebound and contract.

[0049] When this connection assembly is used in a foldable electronic device, when the electronic device is in the unfolded state (refer to Figure 6 ), the flexible circuit board 11 can be contracted in an accordion-like manner, and the flexible circuit board 11 contracts toward the middle in the second direction. At this time, the flexible circuit board 11 is in a compressed state, and the shaper 3 can help the flexible circuit board 11 rebound and contract; when the electronic device is in the folded state (refer to Figure 7 ), the flexible circuit board 11 will be pulled by the main boards 1 of the sub-bodies on both sides, that is, the flexible circuit board 11 will be subjected to the pulling forces of the main boards 1 located on both sides. At this time, the flexible circuit board 11 is in a stretched state. Through the corresponding expansion and contraction of multiple shapers 3, a good buffering effect can be achieved on the pulling forces received by the flexible circuit board 11, and it can avoid excessive deformation and damage caused by dead fold points in the Z-shaped flexible circuit board in the related art. In this way, the number of bending times of the electronic device can be effectively increased, the stability and reliability of the electronic device can be improved, and the service life of the electronic device can be extended.

[0050] For the connection assembly of the electronic device according to the embodiment of the present invention, by providing multiple shapers 3 on the rotational connection mechanism 2 and each shaper 3 being telescopic, during the folding and unfolding processes of the electronic device, through the auxiliary shaping effect of the multiple telescopic shapers 3, the flexible circuit board 11 connected between the main boards 1 of the two sub-bodies can adapt to deform under the force state, reduce the damage caused to the flexible circuit board 11 during the repeated folding process, effectively increase the number of bending times of the electronic device, improve the stability and reliability of the electronic device, and extend the service life of the electronic device.

[0051] According to some embodiments of the present invention, referring to Figure 6 and Figure 7 , the number of shaper groups can be 2 - 4 groups. For example, the shaper groups can be two groups, three groups, or four groups. By setting the number of shaper groups to 2 - 4 groups, it can not only ensure that the shaper 3 has a good shaping and buffering effect, but also can reduce the process difficulty.

[0052] According to some embodiments of the present invention, referring to Figure 6 and Figure 7 , each shaper group includes one shaper 3. Thus, it can not only ensure that the shaper 3 has a good shaping and buffering effect, but also can reduce the process difficulty.

[0053] For example, in the examples of Figure 6 and Figure 7 there are three sets of shapers. Each set of shapers includes a shaper 3. When the electronic device is in the unfolded state, through the auxiliary shaping effect of the shaper 3, the part of the flexible circuit board 11 corresponding to the connection component can be generally shaped into an M shape. When the electronic device is in the folded state, the flexible circuit board 11 is in a stretched state, and the multiple shapers 3 can play a buffering role. When the whole machine changes back from the folded state to the unfolded state, the multiple shapers 3 help the flexible circuit board 11 to rebound and contract, and the part of the flexible circuit board 11 corresponding to the connection component is generally shaped into an M shape again.

[0054] According to some optional embodiments of the present invention, at least one set of shapers includes multiple shapers 3, and the multiple shapers 3 in at least one set of shapers are arranged in the second direction. Thus, the setting of the shapers 3 can be made more flexible, so that at least one set of shapers can provide more support, shaping and buffering effects on the flexible circuit board 11 in the second direction. Optionally, some sets of shapers may include multiple shapers 3. For example, only one set of shapers may include multiple shapers 3, and the multiple shapers 3 in this set of shapers are arranged in the second direction; or each set of shapers includes multiple shapers 3, and the multiple shapers 3 in each set of shapers are arranged in the second direction.

[0055] In some optional embodiments of the present invention, in the embodiment where at least one set of shapers includes multiple shapers 3 and the multiple shapers 3 in at least one set of shapers are arranged in the second direction, the distance between two adjacent shapers 3 in the set of shapers is less than the distance between two adjacent sets of shapers. In the set of shapers including multiple shapers 3, the distance between two adjacent shapers 3 in this set of shapers in the second direction is less than the distance between two adjacent sets of shapers. In this way, the multiple shapers 3 in the set of shapers can be more concentrated, so that this set of shapers can centrally support a certain part of the flexible circuit board 11, enabling multiple sets of shapers to achieve multi-region dispersed support for the flexible circuit board 11, while each set of shapers achieves local region centralized support, thereby playing a better support, buffering and shaping role.

[0056] According to some embodiments of the present invention, at least one set of shapers includes a plurality of shapers 3, and the plurality of shapers 3 in at least one set of shapers are arranged in a first direction. Thus, the arrangement of the shapers 3 can be made more flexible, so that at least one set of shapers can not only provide more support, shaping and buffering effects for the flexible circuit board 11 in a second direction, but also provide more support for the flexible circuit board 11 in the first direction, resulting in a better shaping and buffering effect. Optionally, a part of the sets of shapers may include a plurality of shapers 3. For example, only one set of shapers may include a plurality of shapers 3, and the plurality of shapers 3 in this set of shapers are arranged in the first direction; or each set of shapers includes a plurality of shapers 3, and the plurality of shapers 3 in each set of shapers are arranged in the first direction.

[0057] According to some embodiments of the present invention, referring to Figure 6 and Figure 7 , the free ends 321 of all the shapers 3 in each set of shapers face the same direction, and the free ends 321 of the shapers 3 in adjacent two sets of shapers face opposite directions. For example, the third direction may be the up-down direction, the free ends 321 of all the shapers 3 in each set of shapers all face up or all face down, and the free ends 321 of the shapers 3 in one of the adjacent two sets of shapers face up and the free ends 321 of the shapers 3 in the other set face down. In this way, when the flexible circuit board 11 is wound around the free ends 321 of each shaper 3 and between adjacent two sets of shapers, the part of the flexible circuit board 11 located in the bending area can have a larger length, so that the flexible circuit board 11 has a sufficient amount of stretching and deformation in the second direction. Especially when the flexible circuit board 11 is subjected to a tensile force, the risk of breakage of the flexible circuit board 11 caused by the tensile force can be reduced. And this arrangement can make the flexible circuit board 11 play a better buffering role when in a stretched state; and when the flexible circuit board 11 is in a compressed state, it can better help the flexible circuit board 11 to rebound and shrink into shape, thereby better reducing the risk of damage to the flexible circuit board 11.

[0058] According to some embodiments of the present invention, referring to Figures 5 - 7, the shaper 3 can be telescopically extended and retracted through elastic deformation. Thus, during the unfolding process of the electronic device, the flexible circuit board 11 is deformed under a compressive force. Since the flexible circuit board 11 contacts the free end 321 of the shaper 3 and the shaper 3 is telescopically extended and retracted through elastic deformation in the third direction, due to the elastic recovery and contraction of the flexible circuit board 11, the shaper 3 elongates in the third direction under its own elastic force to assist the flexible circuit board 11 in elastic recovery and contraction; during the folding process of the electronic device, the flexible circuit board 11 is deformed under a tensile force. Since the flexible circuit board 11 contacts the free end 321 of the shaper 3 and the shaper 3 is telescopically extended and retracted through elastic deformation in the third direction, due to the unfolding and elongation of the flexible circuit board 11, the flexible circuit board 11 will squeeze the free end 321 of the shaper 3 in the third direction during deformation, causing the shaper 3 to shorten in the third direction. During this process, the shaper 3 can play a buffering role and reduce the risk of damage to the flexible circuit board 11.

[0059] According to some embodiments of the present invention, referring to Figures 4 - 7 , a through hole 21 for the flexible circuit board 11 to pass through is formed on the rotational connection mechanism 2, and at least a part of the shaper 3 is disposed in the through hole 21. For example, a part of the shaper 3 can be passed through the through hole 21, or all of the shapers 3 can be passed through the through hole 21. One end of the shaper 3 located in the through hole 21 is connected to the inner wall of the through hole 21, and the other end of the shaper 3 located in the through hole 21 constitutes the free end 321 of the shaper 3. The axial direction of the through hole 21 is parallel to the above-mentioned second direction. By providing the through hole 21 for the flexible circuit board 11 to pass through on the rotational connection mechanism 2, it is convenient for the flexible circuit board 11 to pass through the rotational connection mechanism 2, which can be used to avoid the flexible circuit board 11, thereby reducing the acting force of the rotational connection mechanism 2 on the flexible circuit board 11, reducing the risk of damage to the flexible circuit board 11, and making the structure compact. Moreover, by disposing at least a part of the shaper 3 in the through hole 21, it is convenient for the installation and fixation of the shaper 3, can reduce the extra space occupied by the shaper 3, and at the same time enables the shaper 3 to play a better role in supporting, shaping, and buffering.

[0060] According to some alternative embodiments of the present invention, referring to Figures 5 - 7 , the shaper 3 can be telescopically extended and retracted through elastic deformation, and all of the shapers 3 are disposed in the through hole 21. When the shaper 3 elongates to its maximum length, the shaper 3 is in a compressed state or a natural elongation state. In this way, regardless of whether the electronic device is in an unfolded state or a folded state, that is, regardless of whether the flexible circuit board 11 is in a compressed state or a tensile state, it can be ensured that the free end 321 of the shaper 3 remains in contact with the flexible circuit board 11, so as to ensure that the shaper 3 can effectively support, shape, and buffer the flexible circuit board 11.

[0061] According to some embodiments of the present invention, referring toFigures 5 - 7 The shaping device 3 includes: an elastic member 32 which is telescopable in the third direction. The elastic member 32 can be a spring. One end of the elastic member 32 is connected to the rotational connection mechanism 2, and a buffer portion is provided at the other end of the elastic member 32, and this buffer portion constitutes the free end 321 of the shaping device 3. Thus, it is convenient to achieve the telescoping of the shaping device 3 in the third direction, and by providing the buffer portion at the other end of the elastic member 32, the buffer portion contacts the flexible circuit board 11, so as to reduce or prevent damage such as scratches to the flexible circuit board 11 caused by the portion of the shaping device 3 in contact with the flexible circuit board 11.

[0062] Optionally, the other end of the elastic member 32 can be bonded to the buffer portion, or the other end of the elastic member 32 can be embedded in the buffer portion, so as to realize the connection between the elastic member 32 and the buffer portion.

[0063] Optionally, the buffer portion can be a rubber member, a silica gel member or a foam member.

[0064] Optionally, the surface of the buffer portion facing the flexible circuit board 11 is a spherical surface or an arc surface. For example, the buffer portion can be spherical, ellipsoidal or cylindrical, etc. By making the surface of the buffer portion facing the flexible circuit board 11 a spherical surface or an arc surface, the surface of the buffer portion facing the flexible circuit board 11 can be formed into a smooth curved surface, further reducing or preventing damage such as scratches to the flexible circuit board 11 caused by the portion of the shaping device 3 in contact with the flexible circuit board 11.

[0065] In a further embodiment of the present invention, referring to Figures 5 - 7 The shaping device 3 further includes a fixing base 31. One end of the elastic member 32 is connected to the fixing base 31. For example, one end of the elastic member 32 is adhesively or welded to the fixing base 31, and the fixing base 31 is connected to the rotational connection mechanism 2. For example, the fixing base 31 is adhesively or welded to the rotational connection mechanism 2. By providing the fixing base 31, it is convenient to connect and fix the shaping device 3 to the rotational connection mechanism 2.

[0066] Optionally, the fixing base 31 can be a plastic member or a metal member.

[0067] Optionally, when the above-mentioned through hole 21 is formed in the rotational connection mechanism 2 and the shaping device 3 is located in the through hole 21, one end of the fixing base 31 is connected to the inner wall of the through hole 21, and the other end of the fixing base 31 is spaced apart from the inner wall of the through hole 21, so that the elastic member 32 is telescopable in the third direction and the length of the shaping device 3 can be changed in the third direction when the elastic member 32 expands and contracts in the third direction.

[0068] In some alternative embodiments of the present invention, referring to Figures 5 - 7, a guiding cavity 311 for guiding the elastic deformation of the elastic member 32 is formed in the fixing base 31, and one end of the elastic member 32 is located in the guiding cavity 311 and is connected to the inner wall of the guiding cavity 311. By forming the guiding cavity 311 in the fixing base 31, it can play a guiding role in the telescopic deformation of the elastic member 32 in the third direction, so that the elastic member 32 can stably expand and contract along the third direction.

[0069] For example, in Figures 1 - 7 the example, the rotating connection mechanism 2 is formed with the above-mentioned through hole 21, the shaping device group is three groups, and the three shaping devices 3 are all located in the through hole 21, and the three shaping devices 3 are arranged along the second direction. Each group of shaping device groups includes one shaping device 3, and each shaping device 3 is telescopable in the third direction. Each shaping device 3 includes the above-mentioned elastic member 32, a buffer portion and a fixing base 31, and the guiding cavity 311 is formed in the fixing base 31. A part of the elastic member 32 is accommodated in the guiding cavity 311 of the fixing base 31 and is connected to the fixing work, and the other end of the elastic member 32 extends out of the guiding cavity 311 and is provided with a buffer portion.

[0070] The free ends 321 of two adjacent groups of shaping devices 3 face in opposite directions, and two adjacent groups of shaping devices 3 are respectively fixedly connected to the opposite side walls of the through hole 21 through the fixing base 31. One end of the fixing base 31 of each shaping device 3 is connected to the inner wall of the through hole 21 and the other end of the fixing base 31 of each shaping device 3 is spaced apart from the inner wall of the through hole 21. For example, one of the fixing bases 31 of two adjacent groups of shaping devices 3 is connected to the upper side wall of the through hole 21 and the other is connected to the lower side wall of the through hole 21. The fixing base 31 connected to the upper side wall of the through hole 21 is spaced apart from the lower side wall of the through hole 21. The free end 321 of the shaping device 3 connected to the upper side wall of the through hole 21 faces downward. The fixing base 31 connected to the lower side wall of the through hole 21 is spaced apart from the upper side wall of the through hole 21. The free end 321 of the shaping device 3 connected to the lower side wall of the through hole 21 faces upward. The length of the fixing base 31 in the third direction can be about half of the size of the through hole 21 in the third direction.

[0071] During the unfolding process of the electronic device, the flexible circuit board 11 is deformed by the compressive force. The part of the flexible circuit board 11 located in the through hole 21 contacts the free end 321 of the shaping device 3. Due to the elastic contraction of the flexible circuit board 11, the shaping device 3 elongates in the third direction under the elastic force of the elastic member 32 to assist the flexible circuit board 11 in elastic contraction. When the electronic device is in the unfolded state, through the auxiliary shaping effect of multiple shaping devices 3, the part of the flexible circuit board 11 passing through the through hole 21 can be generally shaped into an M shape.

[0072] During the folding process of the electronic device, the flexible circuit board 11 is deformed by the tensile force. The part of the flexible circuit board 11 located within the through hole 21 contacts the free end 321 of the shaper 3. Since the flexible circuit board 11 expands and elongates when unfolded, when the flexible circuit board 11 is deformed, it will squeeze the free end 321 of the shaper 3 in the third direction, causing the elastic member 32 to be compressed in the third direction and the shaper 3 to shorten in the third direction. During this process, the shaper 3 can play a buffering role and reduce the risk of damage to the flexible circuit board 11. When the whole device changes back from the folded state to the unfolded state, multiple shapers 3 help the flexible circuit board 11 to rebound and contract, and the part of the flexible circuit board 11 passing through the through hole 21 is roughly shaped into an M shape again.

[0073] The electronic device according to the second aspect embodiment of the present invention includes: the connection component according to the first aspect embodiment of the present invention above.

[0074] Optionally, the electronic device can have an unfolded state and a folded state. Among them, when the electronic device is in the unfolded state, the two sub-bodies of the electronic device are arranged in the second direction; when the electronic device is in the folded state, the two sub-bodies of the electronic device are stacked in the thickness direction of the sub-body (i.e., the above-mentioned third direction), so that the occupied area of the electronic device can be significantly reduced, facilitating the carrying of the electronic device.

[0075] Optionally, the electronic device can include a flexible display screen 4. The flexible display screen 4 can be arranged on the body. The flexible display screen 4 can be a complete display screen 4. The flexible display screen 4 simultaneously supports and covers the two sub-bodies and also supports and covers the connection component. The flexible display screen 4 is electrically connected to the main boards 1 of the two sub-bodies. Since the flexible display screen 4 can be bent, when the body is folded, the flexible display screen 4 can be folded synchronously with the body. Of course, when the body is unfolded, the flexible display screen 4 is unfolded with the body, so that the foldable electronic device with a display function is realized.

[0076] Refer to Figure 1 and Figure 2 , optionally, when the electronic device includes the flexible display screen 4, the flexible display screen 4 and the main board 1 can be electrically connected through a chip on film 12, and the flexible circuit board 11 and the main board 1 of each sub-body can be electrically connected through the chip on film 12.
