Images and videos can be taken through electronic devices, and remote communication can also be carried out through electronic devices. Usually, the electronic device includes a first shell and a second shell, and the first shell and the second shell are movably connected by a hinge assembly, so that the electronic device can switch between a folded state and an unfolded state. However, in the related art, the structure of the hinge assembly is relatively complex, and the hinge assembly occupies more installation space, resulting in a reduction in the installation space of other components of the electronic device, affecting the space utilization inside the electronic device. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a hinge assembly and an electronic device, which at least solves the problem that the structure of the hinge assembly is relatively complex and the hinge assembly occupies a large installation space, resulting in a reduction in the installation space of other components of the electronic device, affecting the space utilization inside the electronic device.

[0004] In a first aspect, an embodiment of the present application provides a hinge assembly, the hinge assembly comprising: a first swing arm, a second swing arm, a fixed base, a first door panel, and a second door panel;

[0005] The fixed base is provided with a first rotation groove and a second rotation groove, and the first rotation groove and the second rotation groove are arranged opposite to each other, part of the first swing arm is embedded in the first rotation groove, and another part of the first swing arm is fixedly connected to the first door panel, part of the second swing arm is embedded in the second rotation groove, and another part of the second swing arm is fixedly connected to the second door panel, the first swing arm is rotatable in the first rotation groove relative to the central axis of the fixed base, and the second swing arm is rotatable in the second rotation groove relative to the central axis of the fixed base, and the hinge assembly has a folded state and an unfolded state;

[0006] When the first door panel and the second door panel are approaching or moving away from each other, the first door panel drives the first swing arm to rotate in the first rotation groove relative to the central axis of the fixed base, and the second door panel drives the second swing arm to rotate in the second rotation groove relative to the central axis of the fixed base, so that the hinge assembly switches between the folded state and the unfolded state.

[0007] In a second aspect, an embodiment of the present application provides an electronic device, the electronic device comprising a first housing, a second housing, and the hinge assembly described in the first aspect;

[0008] The first housing is connected to the first door panel, the second housing is connected to the second door panel, and the electronic device has a folded state and an unfolded state;

[0009] When the electronic device switches from a folded state to an unfolded state, the first shell and the second shell move away from each other, and the first door panel and the second door panel move away from each other; when the electronic device switches from an unfolded state to a folded state, the first shell and the second shell move closer to each other, and the first door panel and the second door panel move closer to each other.

[0010] In the embodiment of the present application, since part of the first swing arm is embedded in the first rotating groove, another part of the first swing arm is fixedly connected to the first door panel, and part of the second swing arm is embedded in the second rotating groove, and another part of the second swing arm is fixedly connected to the second door panel, the first swing arm is rotatable in the first rotating groove relative to the central axis of the fixed base, and the second swing arm is rotatable in the second rotating groove relative to the central axis of the fixed base. Therefore, when the first swing arm rotates in the first rotating groove relative to the central axis of the fixed base, and the second swing arm rotates in the second rotating groove relative to the central axis of the fixed base, the state of the hinge assembly can be changed, that is, when the state of the hinge changes, the first swing arm rotates in the first rotating groove relative to the central axis of the fixed base, and the second swing arm rotates in the second rotating groove relative to the central axis of the fixed base. In addition, when the hinge assembly is applied to an electronic device, the electronic device has a first shell and a second shell, so that the first shell can be connected to the first door panel, and the second shell can be connected to the second door panel, so that when the state of the electronic device needs to be switched, force is applied to the first shell and the second shell, so that the first shell and the second shell can respectively transmit force to the hinge assembly, so that the state of the hinge assembly changes, and then the state of the electronic device changes. Specifically, when the first shell and the second shell are close to or away from each other, the first shell drives the first door panel to move, and the second shell drives the second door panel to move, so that the first door panel and the second door panel are close to or away from each other, so that the first door panel can drive the first swing arm to rotate in the first rotating groove relative to the central axis of the fixed base, and the second door panel drives the second swing arm to rotate in the second rotating groove relative to the central axis of the fixed base, so that the first swing arm and the second swing arm are close to or away from each other, so that the hinge assembly switches between the folded state and the unfolded state, and the first shell and the second shell are close to or away from each other, so that the electronic device can switch between the unfolded state and the folded state.

[0011] That is, in the embodiment of the present application, by setting the first swing arm, the second swing arm, the fixed base, the first door panel and the second door panel, the function of the hinge assembly can be realized, and, by setting the first swing arm and the second swing arm, the first swing arm is equivalent to replacing the virtual swing arm and the synchronous swing arm, and the second swing arm is equivalent to replacing the virtual swing arm and the synchronous swing arm, so that the structure of the hinge assembly in the embodiment of the present application is simpler, and the first swing arm and the second swing arm are arranged relative to each other, so as to avoid occupying more space in the axial direction of the hinge assembly, thereby avoiding the problem of reducing the space occupied by other components inside the electronic device and affecting the space utilization inside the electronic device. That is, through the hinge assembly provided in the embodiment of the present application, not only the structure of the hinge assembly can be simplified, but also it is beneficial to improve the space utilization of the electronic device, so that the space occupied by other components inside the electronic device is increased.

[0022] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] Before explaining the hinge assembly provided in the embodiment of the present application, the application scenario of the hinge assembly provided in the embodiment of the present application is first specifically described: In the related art, the hinge assembly includes a synchronous swing arm, a virtual swing arm, and a door panel. The synchronous swing arm and the virtual swing arm are both connected to the door panel. The door panel can support the display screen of the electronic device, so that the display screen of the electronic device can also be supported at the hinge assembly, avoiding the problem that the display screen may sink at the hinge assembly. In addition, the synchronous swing arm and the virtual swing arm are arranged along the axial direction of the hinge assembly. During the activity of the hinge assembly, the synchronous swing arm and the virtual swing arm move simultaneously. However, in the related art, by setting the synchronous swing arm and the virtual swing arm, the structure of the hinge assembly is complicated, and the synchronous swing arm and the virtual swing arm are arranged along the axial direction of the hinge assembly, resulting in more space in the axial direction of the hinge assembly being occupied, and then resulting in more space inside the electronic device being occupied, resulting in a reduction in the space occupied by other components inside the electronic device, affecting the space utilization rate inside the electronic device.

[0024] like Figures 1 to 6 As shown, the hinge assembly includes: a first swing arm 10 , a second swing arm 20 , a fixed base 30 , a first door panel 60 and a second door panel 70 .

[0025] A first rotating groove 31 and a second rotating groove 32 are provided on the fixed base 30, and the first rotating groove 31 and the second rotating groove 32 are arranged opposite to each other. Part of the first swing arm 10 is embedded in the first rotating groove 31, and another part of the first swing arm 10 is fixedly connected to the first door panel 60, and another part of the second swing arm 20 is embedded in the second rotating groove 32, and another part of the second swing arm 20 is fixedly connected to the second door panel 70. The first swing arm 10 is rotatable relative to the central axis of the fixed base 30 in the first rotating groove 31, and the second swing arm 20 is rotatable relative to the central axis of the fixed base 30 in the second rotating groove 32, and the hinge assembly has a folded state and an unfolded state; when the first door panel 60 and the second door panel 70 are close to or away from each other, the first door panel 60 drives the first swing arm 10 to rotate in the first rotating groove 30 relative to the central axis of the fixed base 30, and the second door panel 70 drives the second swing arm 20 to rotate in the second rotating groove 32 relative to the central axis of the fixed base 30, so that the hinge assembly switches between the folded state and the unfolded state.

[0026] In the embodiment of the present application, since part of the first swing arm 10 is embedded in the first rotation groove 31, another part of the first swing arm 10 is fixedly connected to the first door panel 60, part of the second swing arm 20 is embedded in the second rotation groove 32, and another part of the second swing arm 20 is fixedly connected to the second door panel 70, the first swing arm 10 is rotatable relative to the central axis of the fixed base 30 in the first rotation groove 31, and the second swing arm 20 is rotatable relative to the central axis of the fixed base 30 in the second rotation groove 32. Therefore, when the first swing arm 10 rotates relative to the central axis of the fixed base 30 in the first rotation groove 31, and the second swing arm 20 rotates relative to the central axis of the fixed base 30 in the second rotation groove 32, the state of the hinge assembly can be changed, that is, when the state of the hinge changes, the first swing arm 10 rotates relative to the central axis of the fixed base 30 in the first rotation groove 31, and the second swing arm 20 rotates relative to the central axis of the fixed base 30 in the second rotation groove 32. In addition, when the hinge assembly is applied to an electronic device, the electronic device has a first shell and a second shell, and the first shell can be connected to the first door panel 60, and the second shell can be connected to the second door panel 70, so that when the state of the electronic device needs to be switched, force is applied to the first shell and the second shell, so that the first shell and the second shell can respectively transmit force to the hinge assembly, so that the state of the hinge assembly changes, and then the state of the electronic device changes. Specifically, when the first shell and the second shell approach or move away from each other, the first shell drives the first door panel 60 to move, and the second shell drives the second door panel 70 to move, so that the first door panel 60 and the second door panel 70 approach or move away from each other, so that the first door panel 60 can drive the first swing arm 10 to rotate in the first rotating groove 30 relative to the central axis of the fixed base 30, and the second door panel 70 drives the second swing arm 20 to rotate in the second rotating groove 32 relative to the central axis of the fixed base 30, so that the first swing arm 10 and the second swing arm 20 approach or move away from each other, so that the hinge assembly switches between the folded state and the unfolded state, and the first shell and the second shell approach or move away from each other, so that the electronic device can be switched between the unfolded state and the folded state.

[0027] That is, in the embodiment of the present application, by setting the first swing arm 10, the second swing arm 20, the fixed base 30, the first door panel 60 and the second door panel 70, the function of the hinge assembly can be realized, and, by setting the first swing arm 10 and the second swing arm 20, the first swing arm 10 is equivalent to replacing the virtual swing arm and the synchronous swing arm, and the second swing arm 20 is equivalent to replacing the virtual swing arm and the synchronous swing arm, so that the structure of the hinge assembly in the embodiment of the present application is simpler, and the first swing arm 10 and the second swing arm 20 are arranged relative to each other, so as to avoid occupying more space in the axial direction of the hinge assembly, thereby avoiding the problem of reducing the space occupied by other components inside the electronic device and affecting the space utilization inside the electronic device. That is, through the hinge assembly provided in the embodiment of the present application, not only the structure of the hinge assembly can be simplified, but also it is beneficial to improve the space utilization of the electronic device, so that the space occupied by other components inside the electronic device is increased.

[0028] It should be noted that when the first door panel 60 and the second door panel 70 are close to each other, the hinge assembly switches from the unfolded state to the folded state; when the first door panel 60 and the second door panel 70 are away from each other, the hinge assembly switches from the folded state to the unfolded state.

[0029] In addition, in some embodiments, the first swing arm 10 includes a first sliding portion 11 and a first connecting portion 12 connected to each other, and the second swing arm 20 includes a second sliding portion 21 and a second connecting portion 22 connected to each other, the first sliding portion 11 is embedded in the first rotating groove 31, and the first sliding portion 11 can rotate relative to the central axis of the fixed base 30 in the first rotating groove 31, the second sliding portion 21 is embedded in the second rotating groove 32, and the second sliding portion 21 can rotate relative to the central axis of the fixed base 30 in the second rotating groove 32, the first connecting portion 12 is fixedly connected to the first door panel 60, and the second connecting portion 22 is fixedly connected to the second door panel 70.

[0030] Since the first sliding portion 11 is embedded in the first rotating groove 31 and the first sliding portion 11 can rotate in the first rotating groove 31 relative to the central axis of the fixed base 30, and the second sliding portion 21 is embedded in the second rotating groove 32 and the second sliding portion 21 can rotate in the second rotating groove 32 relative to the central axis of the fixed base 30, therefore, when the first sliding portion 11 rotates in the first rotating groove 31 relative to the central axis of the fixed base 30 and the second sliding portion 21 rotates in the second rotating groove 32 relative to the central axis of the fixed base 30, the state of the hinge assembly can be changed, that is, when the state of the hinge changes, the first sliding portion 11 rotates in the first rotating groove 31 relative to the central axis of the fixed base 30 and the second sliding portion 21 rotates in the second rotating groove 32 relative to the central axis of the fixed base 30. In addition, the first connecting portion 12 is connected to the first door panel 60, and the second connecting portion 22 is connected to the second door panel 70, so that when the hinge assembly is applied to an electronic device, the first shell can be connected to the first door panel 60, and the second shell can be connected to the second door panel 70, so that when the state of the electronic device needs to be switched, force is applied to the first shell and the second shell, so that the first shell transfers the force to the first door panel 60, and the first door panel 60 transfers the force to the first sliding portion 11 through the first connecting portion 12, so that the first sliding portion 11 rotates in the first rotating groove 31 relative to the central axis of the fixed base 30, and the second shell transfers the force to the second door panel 70, and the second door panel 70 transfers the force to the second sliding portion 21 through the second connecting portion 22, so that the second sliding portion 21 rotates in the second rotating groove 32 relative to the central axis of the fixed base 30, so that the state of the hinge assembly changes, and then the state of the electronic device changes. That is, by providing the first sliding part 11, the first connecting part 12, the second sliding part 21 and the second connecting part 22, it is convenient to connect the first door panel 60 with the first swing arm 10, and to connect the second door panel 70 with the second swing arm 20, so as to drive the first sliding part 11 to rotate in the first rotating groove 31 relative to the central axis of the fixed base 30, and the second sliding part 12 to rotate in the second rotating groove 32 relative to the central axis of the fixed base 30 when the first door panel 60 and the second door panel 70 approach or move away from each other.

[0031] In addition, in some embodiments, the first sliding portion 11 and the second sliding portion 22 are both bent structures with an arc, and the bottom of the first rotating groove 31 and the bottom of the second rotating groove 32 both have an arc.

[0032] When the first door panel 60 and the second door panel 70 are close to or away from each other, the first door panel 60 drives the first sliding portion 11 to rotate relative to the central axis of the fixed base 30 in the first rotation groove 31 through the first connecting portion 12, and the second door panel 70 drives the second sliding portion 21 to rotate relative to the central axis of the fixed base 30 in the second rotation groove 32 through the second connecting portion 22, the first sliding portion 11 contacts the bottom of the first rotation groove 31, and the second sliding portion 12 contacts the bottom of the second rotation groove 32, so that the first sliding portion 11 and the second sliding portion 22 are both bent structures with an arc, and the first rotation groove 31 is provided. The bottom of the groove of the first rotating groove 31 and the bottom of the groove of the second rotating groove 32 both have an arc, which is equivalent to the first sliding part 11 with an arc rotating at the bottom of the groove of the first rotating groove 31 with an arc, and the second sliding part 21 with an arc rotating at the bottom of the groove of the second rotating groove 32 with an arc, so that the first sliding part 11 is convenient for rotating relative to the central axis of the fixed base 30 in the first rotating groove 31, and the second sliding part 21 is convenient for rotating relative to the central axis of the fixed base 30 in the second rotating groove 32, and it can be ensured that the first sliding part 11 and the second sliding part 21 drive the first connecting part 12 and the second connecting part 22 to move away from or approach each other. That is, by setting in some embodiments, the first sliding part 11 and the second sliding part 22 are both bent structures and have an arc, and the bottom of the first rotating groove 31 and the bottom of the second rotating groove 32 both have an arc, which can facilitate the first sliding part 11 to rotate relative to the central axis of the fixed base 30 in the first rotating groove 31, and facilitate the second sliding part 21 to rotate relative to the central axis of the fixed base 30 in the second rotating groove 32.

[0033] In addition, in some embodiments, the hinge assembly may further include an elastic assembly 40, the fixed base 30 includes a movable part 301 and a fixed part 302, and the movable part 301 and the fixed part 302 are arranged along the axial direction of the hinge assembly; the first end of the elastic assembly 40 is fixed, the second end of the elastic assembly 40 abuts against the movable part 301, the movable part 301 is movable relative to the fixed part 302, the movable part 301 and the fixed part 302 are provided with a first rotation groove 31, and the movable part 301 and the fixed part 302 are provided with a second rotation groove 32; when the hinge assembly is in an unfolded state, the movable part 301 is located at a first position, and the length of the elastic assembly 40 is a first length, and when the hinge assembly is in a folded state, the movable part 301 is located at a second position, and the length of the elastic assembly 40 is a second length, and the second length is greater than the first length.

[0034] Since the movable part 301 and the fixed part 302 are arranged along the axial direction of the hinge assembly, the movable part 301 and the fixed part 302 are provided with a first rotation groove 31, and the movable part 301 and the fixed part 302 are provided with a second rotation groove 32, the first sliding part 11 can be located in the first rotation groove 31 on the movable part 301 and the fixed part 302, and the second sliding part 21 can be located in the second rotation groove 32 on the movable part 301 and the fixed part 302, so that the first sliding part 11 is in the first rotation groove 31 on the movable part 301 and the fixed part 302. When the first rotating groove 31 rotates relative to the central axis of the fixed base 30, and the second sliding part 21 rotates relative to the central axis of the fixed base 30 in the second rotating groove 32, the first sliding part 11 can contact the movable part 301 and the fixed part 302 at the same time, and the second sliding part 21 can contact the movable part 301 and the fixed part 302 at the same time, that is, the first sliding part 11 can apply force to the movable part 301, and the second sliding part 21 can apply force to the movable part 301, so that the movable part 301 moves relative to the fixed part 302. Since the first end of the elastic component 40 is fixed and the second end of the elastic component 40 abuts against the movable part 301, when the movable part 301 moves, the movable part 301 can apply force to the elastic component 40, or the elastic component 40 applies force to the movable part 301, so that the movable part 301 can move when the first sliding part 11 and the second sliding part 21 move. Specifically, when the hinge assembly switches from the folded state to the unfolded state, the first sliding part 11 rotates in the first rotating groove 31 relative to the central axis of the fixed base 30, and the second sliding part 21 rotates in the second rotating groove 32 relative to the central axis of the fixed base 30, so that the first sliding part 11 and the second sliding part 21 apply force to the movable part 301, so that the movable part 301 applies force to the elastic component 40, so that the elastic component 40 is compressed, until the hinge assembly is in the unfolded state, the movable part 301 moves to the first position, and the elastic component 40 is compressed to the first length; when the hinge assembly switches from the unfolded state to the folded state, the first sliding part 11 rotates in the first rotating groove 31 relative to the central axis of the fixed base 30, and the second sliding part 21 rotates in the second rotating groove 32 relative to the central axis of the fixed base 30, so that the elastic component 40 applies force to the movable part 301, that is, the elastic component 40 stretches, until the hinge assembly is in the folded state, the movable part 301 moves to the second position, and the elastic component 40 is stretched to the second length. In addition, when the first sliding part 11 and the second sliding part 21 rotate relative to the central axis of the fixed base 30, the movable part 301 can apply force to the elastic component 40, or the elastic component 40 applies force to the movable part 301, so that the first sliding part 11 and the second sliding part 21 can be subjected to force, so that the user can feel the damping feeling when using the hinge assembly, thereby improving the user experience.

[0035] It should be noted that, in the embodiment of the present application, the elastic component 40 may be a spring.

[0036] In addition, in some embodiments, a first sub-groove 3011 and a second sub-groove 3012 are provided on the movable portion 301, and the first sub-groove 3011 is arranged opposite to the second, and a third sub-groove 3021 and a fourth sub-groove 3022 are provided on the fixed portion 302, and the third sub-groove 3021 and the fourth sub-groove 3022 are arranged opposite to each other, and the first sliding portion 11 is embedded in the first sub-groove 3011 and the third sub-groove 3021 at the same time, and the first sub-groove 3011 and the third sub-groove 3021 form at least a portion of the first rotation groove 31, and the second sliding portion 21 is embedded in the second sub-groove 3012 and the fourth sub-groove 3022 at the same time, and the second sub-groove 3012 and the fourth sub-groove 3022 form at least a portion of the second rotation groove 32, and the first sliding portion 11 contacts the groove wall of the first sub-groove 3011, and the second sliding portion 21 contacts the groove wall of the second sub-groove 3012.

[0037] Since the first sub-groove 3011 and the third sub-groove 3021 form at least a portion of the first rotating groove 31, when the first sliding part 11 is set in the first rotating groove 31, the first sliding part 11 can be embedded in the first sub-groove 3011 and the third sub-groove 3021 at the same time, and the first sliding part 11 can contact the groove wall of the first sub-groove 3011, so that when the first sliding part 11 rotates relative to the central axis of the fixed base 30, the first sliding part 11 can directly apply force to the groove wall of the first sub-groove 3011, that is, apply force to the movable part 301, so that the movable part 301 applies force to the elastic component 40, so that the reaction force of the elastic component 40 can be transmitted to the first sliding part 11 through the movable part 301, and then transmitted to the first door panel 60, so that the user feels the damping. In addition, since the second sub-groove 3012 and the fourth sub-groove 3022 form at least a portion of the second rotating groove 32, when the second sliding portion 21 is set in the second rotating groove 32, the second sliding portion 21 can be embedded in the second sub-groove 3012 and the fourth sub-groove 3021 at the same time, and the second sliding portion 21 can contact the groove wall of the second sub-groove 3012, so that when the second sliding portion 21 rotates relative to the central axis of the fixed base 30, the second sliding portion 21 can directly apply force to the groove wall of the second sub-groove 3012, that is, apply force to the movable portion 301, so that the movable portion 301 applies force to the elastic component 40, so that the reaction force of the elastic component 40 can be transmitted to the second sliding portion 21 through the movable portion 301, and then transmitted to the second door panel 70, so that the user feels a damping feeling. That is, by providing a first sub-groove 3011 and a second sub-groove 3012 on the movable part 301 and a third sub-groove 3021 and a fourth sub-groove 3022 on the fixed part 302, it is convenient to form the first rotating groove 31 and the second rotating groove 32, and it can ensure that the first sliding part 11 and the second sliding part 21 can generate a damping feeling for the user when rotating.

[0038] In addition, in some embodiments, the groove wall of the first sub-groove 3011 has a first curved surface 3013, the first sliding portion 11 has a second curved surface 111, the first curved surface 3013 faces the second curved surface 111, and the first curved surface 3013 is in contact with the second curved surface 111; the groove wall of the second sub-groove 3012 has a third curved surface 3014, the second sliding portion 21 has a fourth curved surface 211, the third curved surface 3014 faces the fourth curved surface 211, and the third curved surface 3014 is in contact with the fourth curved surface 211.

[0039] Since the groove wall of the first sub-groove 3011 has a first curved surface 3013 and the first sliding part 11 has a second curved surface 111, when the first sliding part 11 is placed in the first sub-groove 3011, the first curved surface 3013 can be made to contact the second curved surface 111, so that when the first sliding part 11 rotates relative to the central axis of the fixed base 30, the second curved surface 111 on the first sliding part 11 can contact different positions of the first curved surface 3013, so that the force applied by the first sliding part 11 to the movable part 301 will be different, and the force applied by the movable part 301 to the elastic component 40 will be different, and then the reaction force of the elastic component 40 on the movable part 301 will be different, so that the force transmitted by the first sliding part 11 to the first door panel 60 will be different, and finally the user will feel different damping. Similarly, since the groove wall of the second sub-groove 3012 has a third curved surface 3014 and the second sliding portion 21 has a fourth curved surface 211, when the second sliding portion 21 is placed in the second sub-groove 3012, the third curved surface 3014 can be made to contact the fourth curved surface 211, so that when the second sliding portion 21 rotates relative to the central axis of the fixed base 30, the fourth curved surface 211 on the second sliding portion 21 can contact different positions of the third curved surface 3014, so that the force applied by the second sliding portion 21 to the movable portion 301 will be different, and the force applied by the movable portion 301 to the elastic component 40 will be different, and then the reaction force of the elastic component 40 on the movable portion 301 will be different, so that the force transmitted by the second sliding portion 21 to the second door panel 70 will be different, and finally the user will feel different damping. That is, by providing the first curved surface 3013, the second curved surface 111, the third curved surface 3014 and the fourth curved surface 211, the damping feeling felt by the user can be changed when the first sliding part 11 and the second sliding part 21 rotate relative to the central axis of the fixed base 30, thereby improving the user experience.

[0040] In addition, in some embodiments, the second curved surface 111 and the fourth curved surface 211 both have a convex surface 1111 and a concave surface 1112, and the convex surface 1111 is adjacent to the concave surface 1112; when the hinge assembly is in an unfolded state, the first curved surface 3013 contacts the convex surface 1111 on the second curved surface 111, and the third curved surface 3014 contacts the convex surface 1111 on the fourth curved surface 211; when the hinge assembly is in a folded state, the first curved surface 3013 contacts the concave surface 1112 on the second curved surface 111, and the third curved surface 3014 contacts the concave surface 1112 on the fourth curved surface 211.

[0041] Since the second curved surface 111 and the fourth curved surface 211 both have a convex surface 1111 and a concave surface 1112, and the convex surface 1111 is adjacent to the concave surface 1112, therefore, when force is applied to the first sliding portion 11 through the first door panel 60 so that the first sliding portion 11 rotates in the first rotating groove 31 relative to the central axis of the fixed base 30, and force is applied to the second sliding portion 21 through the second door panel 70 so that the second sliding portion 21 rotates in the second rotating groove 32 relative to the central axis of the fixed base 30, the convex surface 1111 and the concave surface 1112 on the second curved surface 111 of the first sliding portion 11 can alternately contact the first curved surface 3013 of the first sub-groove 3011, and the convex surface 1111 and the concave surface 1112 on the fourth curved surface 211 of the second sliding portion 21 can alternately contact the third curved surface 3014 on the second sub-groove 3012, so that the torque of the electronic device is different when in the unfolded state or the folded state. Specifically, when the hinge assembly is in the unfolded state, that is, the electronic device is in the unfolded state, the first curved surface 3013 contacts the convex surface 1111 on the second curved surface 111, and the third curved surface 3014 contacts the convex surface 1111 on the fourth curved surface 211, so that the compression amount of the elastic component 40 compressed by the movable part 301 is large, so that the torque of the electronic device in the unfolded state is large, ensuring that the electronic device is effectively unfolded, and avoiding the problem of uneven unfolding when the electronic device is unfolded in the related art; when the hinge assembly is in the folded state, that is, the electronic device is in the folded state, the first curved surface 3013 contacts the concave surface 1112 on the second curved surface 111, and the third curved surface 3014 contacts the concave surface 1112 on the fourth curved surface 211, so that the compression amount of the elastic component 40 compressed by the movable part 301 is small, and the torque of the electronic device in the folded state is small, ensuring that the electronic device can be opened more easily in the folded state.

[0042] It should be noted that, in the embodiment of the present application, the first curved surface 3013 and the third curved surface 3014 may also have a convex surface 1111, so that when the hinge assembly is in the unfolded state, the convex surface 1111 on the first curved surface 3013 contacts the convex surface 1111 on the second curved surface 111, and the convex surface 1111 on the third curved surface 3014 contacts the convex surface 1111 on the fourth curved surface 211; when the hinge assembly is in the folded state, the convex surface 1111 on the first curved surface 3013 contacts the concave surface 1112 on the second curved surface 111, and the convex surface 1111 on the third curved surface 3014 contacts the concave surface 1112 on the fourth curved surface 211. Through such a setting, when the electronic device is in the unfolded state, the moment of the electronic device can be further increased to ensure that the electronic device is effectively unfolded; when the electronic device is in the folded state, the moment of the electronic device is further reduced to ensure that the electronic device can be further opened in the folded state.

[0043] In addition, in some embodiments, the hinge assembly may include a blocking member 50, which is fixed in position and spaced apart from the movable portion 301. The blocking member 50 is connected to a sliding rod 51, which passes through the movable portion 301. The elastic component 40 is sleeved on the sliding rod 51, and the first end of the elastic component 40 abuts against the blocking member 50 to fix the first end of the elastic component 40.

[0044] Since the blocking member 50 is fixed in position and the blocking member 50 and the movable part 301 are spaced apart, there is a distance between the blocking member 50 and the movable part 301, so that the elastic component 40 can be arranged between the blocking member 50 and the movable part 301, and the first end of the elastic component 40 is released from the blocking member 50, so that the first end of the elastic component 40 is fixed. Since the blocking member 50 is connected with the slide bar 51, and the slide bar 51 is passed through the movable part 301, the elastic component 40 can be sleeved on the slide bar 51, so that the slide bar 51 can limit the elastic component 40, avoiding the problem that the position of the elastic component 40 may be offset during the compression of the elastic component 40, and the slide bar 51 can also guide the movable part 301, avoiding the problem that the movable part 301 is offset during the activity.

[0045] In addition, in some embodiments, the hinge assembly may further include a hinge cover (not shown in the figure), the hinge cover covers the fixed base 30, the first swing arm 10 and the second swing arm 20, and the fixing portion 302 is fixedly connected to the hinge cover.

[0046] Since the hinge cover covers the fixed base 30, the first swing arm 10 and the second swing arm 20, the hinge cover can protect the fixed base 30, the first swing arm 10 and the second swing arm 20, and prevent the fixed base 30, the first swing arm 10 and the second swing arm 20 from being easily damaged. In addition, the hinge cover can also improve the aesthetics of the hinge assembly and prevent the fixed base 30, the first swing arm 10 and the second swing arm 20 from being directly exposed to the outside of the hinge assembly. In addition, the fixing part 302 is fixedly connected to the hinge cover, so that the hinge cover is equivalent to a fixed position provided for the fixing part 302, which facilitates the fixing part 302 to be fixed.

[0047] It should be noted that, when the hinge assembly may include a blocking member 50 and a hinge cover, the blocking member 50 may be fixed to the hinge cover, so that the hinge cover provides a fixed position for the blocking member 50 to facilitate fixing of the blocking member 50.

[0048] In addition, in some embodiments, the first connection part 12 and the second connection part 22 are both provided with a fixing boss 121, and the first door panel 60 and the second door panel 70 are both provided with a fixing groove 61, and the fixing boss 121 is embedded in the fixing groove 61. Through such a setting, when the first connection part 12 needs to be connected to the first door panel 60, the fixing boss 121 on the first connection part 12 can be directly embedded in the fixing groove 61 on the first door panel 60, so as to complete the connection between the first connection part 12 and the first door panel 60, and when the second connection part 22 needs to be connected to the second door panel 70, the fixing boss 121 on the second connection part 22 can be directly embedded in the fixing groove 61 on the second door panel 70, so as to complete the connection between the second connection part 22 and the second door panel 70. That is, by providing the fixing boss 121 and the fixing groove 61, the connection between the first connection part 12 and the first door panel 60 and the connection between the second connection part 22 and the second door panel 70 can be facilitated.

[0049] Of course, in the embodiment of the present application, the first connecting portion 12 may also be connected to the first door panel 60 via a fixing member, and the second connecting portion 22 may also be connected to the second door panel 70 via a fixing member, and the fixing member includes but is not limited to bolts, pins, etc.

[0050] In the embodiment of the present application, by setting the first swing arm 10, the second swing arm 20, the fixed base 30, the first door panel 60 and the second door panel 70, the function of the hinge assembly can be realized, and by setting the first swing arm 10 and the second swing arm 20, the first swing arm 10 is equivalent to replacing the virtual swing arm and the synchronous swing arm, and the second swing arm 20 is equivalent to replacing the virtual swing arm and the synchronous swing arm, so that the structure of the hinge assembly in the embodiment of the present application is simpler, and the first swing arm 10 and the second swing arm 20 are arranged relative to each other, so as to avoid occupying more space in the axial direction of the hinge assembly, thereby avoiding the problem of reducing the space occupied by other components inside the electronic device and affecting the space utilization inside the electronic device. That is, the hinge assembly provided in the embodiment of the present application can not only simplify the structure of the hinge assembly, but also help to improve the space utilization of the electronic device, so that the space occupied by other components inside the electronic device is increased.

[0052] The first shell is connected to the first door panel 60, and the second shell is connected to the second door panel 70. The electronic device has a folded state and an unfolded state. When the electronic device switches from the folded state to the unfolded state, the first shell and the second shell move away from each other, and the first door panel 60 and the second door panel 70 move away from each other. When the electronic device switches from the unfolded state to the folded state, the first shell and the second shell move closer to each other, and the first door panel 60 and the second door panel 70 move closer to each other.

[0053] In the embodiment of the present application, by setting the first swing arm 10, the second swing arm 20, the fixed base 30, the first door panel 60 and the second door panel 70, the function of the hinge assembly can be realized, and by setting the first swing arm 10 and the second swing arm 20, the first swing arm 10 is equivalent to replacing the virtual swing arm and the synchronous swing arm, and the second swing arm 20 is equivalent to replacing the virtual swing arm and the synchronous swing arm, so that the structure of the hinge assembly in the embodiment of the present application is simpler, and the first swing arm 10 and the second swing arm 20 are arranged relative to each other, avoiding occupying more space in the axial direction of the hinge assembly, thereby avoiding the problem of reducing the space occupied by other components inside the electronic device and affecting the space utilization inside the electronic device.
