Description

Technical Field

[0001] The present application belongs to the technical field of folding devices, and in particular relates to a folding device, a housing assembly and an electronic device. Background Art

[0002] Competition in the mobile terminal industry is increasingly trending towards large screens and ultra-thin devices, but large screens make the entire device too large and inconvenient to carry. Foldable electronic devices can solve the above problem by changing the size of the electronic device due to their folding function, and are now popular with a large number of users. Electronic devices rely on a folding device to achieve the folding function. The folding device usually includes a torque mechanism, which is used to provide torque for the folding device. However, the torque value provided by the torque mechanism is currently constant and cannot be adjusted. Summary of the invention

[0003] In view of this, the first aspect of the present application provides a folding device, comprising:

[0004] A base assembly comprises a base and a rotating shaft arranged on the base, wherein the axial direction of the rotating shaft is set as a sliding direction;

[0005] A rotating member, rotatably connected to the base, wherein the end side of the rotating member along the sliding direction is provided with a first cam member;

[0006] a second cam member, sleeved on the rotating shaft and capable of cooperating with the first cam member, so that the second cam member can slide along the sliding direction when the rotating member rotates relative to the base;

[0007] an elastic member, sleeved on the rotating shaft and having one end abutting against a side of the second cam member away from the first cam member;

[0008] a blocking member, sleeved on the rotating shaft and abutting against the other end of the elastic member; and

[0009] An adjusting mechanism is arranged on the base and connected to the blocking member, and the adjusting mechanism can make the blocking member slide along the sliding direction, thereby compressing or stretching the elastic member.

[0010] The folding device provided in the first aspect of the present application utilizes the cooperation of the base, the rotating shaft, the rotating member, the first cam member, the second cam member, the elastic member, and the blocking member to enable the first cam member and the second cam member to cooperate with each other when the rotating member rotates, thereby compressing the elastic member, thereby causing the rotating member of the folding device to generate torque. On this basis, the present application adds an adjustment mechanism, which is arranged on the base and connected to the blocking member at the same time, and the adjustment mechanism can cause the blocking member to slide along the sliding direction. Since the blocking member abuts against the other end of the elastic member, the blocking member can drive the other end of the elastic member to slide along the sliding direction. Since one end of the elastic member abuts against the second cam member, the second cam member cooperates with the first cam member on the rotating member, resulting in that when the other end of the elastic member slides, it will not drive one end of the elastic member to slide, and one end of the elastic member remains fixed, so that the elastic member is compressed or stretched, thereby changing the initial state of the elastic member. In this way, when the rotating member rotates, the elastic member gives different rebound forces to the second cam member when it is compressed by the cooperation of the first cam member and the second cam member: increase or decrease, thereby changing the torque of the rotating member in the folding device.

[0011] In summary, the present application utilizes the adjustment mechanism and the blocking member to compress or stretch the elastic member so as to change the initial state of the elastic member, thereby changing the rebound force given by the elastic member to the second cam member, and further changing the torque of the rotating member in the folding device. In other words, the folding device provided by the present application can adjust the torque without disassembling the parts, and can also assemble folding devices with different torque values ​​by adjusting the compression value of the elastic member without replacing the parts, so as to meet the needs of different user groups. And when the mechanical properties of the elastic member decay after the folding device has been used for a period of time, the adjustment mechanism can be used to readjust the torque of the folding device.

[0012] A second aspect of the present application provides a shell assembly, which includes a first shell, a second shell, and a folding device as provided in the first aspect of the present application, and the folding device is connected between the first shell and the second shell.

[0013] The shell assembly provided in the second aspect of the present application can adjust the torque value of the shell assembly without disassembling or replacing parts by adopting the folding device provided in the first aspect of the present application.

[0014] A third aspect of the present application provides an electronic device, comprising a flexible screen and a shell assembly as provided in the second aspect of the present application, wherein the flexible screen is arranged on the same side of the first shell, the second shell, and the folding device.

[0015] The electronic device provided in the third aspect of the present application, by adopting the shell assembly provided in the second aspect of the present application, can adjust the torque value of the shell assembly without disassembling or replacing parts.

DETAILED DESCRIPTION

[0043] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0044] With the market demand for the "display area" of terminal products such as mobile phones and tablets, the competition in the mobile terminal industry is increasingly tending towards large screens and ultra-thinness. However, large screens make the size of the whole machine too large and inconvenient to carry. The smartphone industry is ushering in an experience revolution brought about by form innovation. The display form of mobile phone products has developed from the initial hard screen to flexible screen, from small screen to large screen, from static mechanism to motion mechanism. Recently, major mobile phone manufacturers have been developing folding screens, striving to expand the form and display boundaries of mobile phone products, so that they have the functions of mobile phones, tablets and even computers. As an electronic device with a new display form, the foldable display terminal can be unfolded or closed due to its folding function, and has a larger display area in the unfolded state and a smaller overall size in the folded state, which can solve the above problems. It is now loved by the majority of users.

[0045] The foldable display terminal relies on the folding device inside it to achieve the folding function. The folding device usually uses a torque mechanism to provide torque to the folding device to ensure the stability of the folding device during rotation. At present, the torque value that the torque mechanism can provide is usually fixed and cannot be adjusted. However, in the actual production process of the folding device, due to the processing tolerance and assembly errors of the parts, even if the torque mechanism is assembled with the same batch of parts with the same parameters, when the torque test is performed after all the parts are assembled, there will be large differences in the test results of each folding device. If the torque test of the torque mechanism in the folding device does not meet the design standards, it needs to be scrapped or reworked and then reassembled and tested. Due to the existence of current parts manufacturing and assembly errors, the torque test yield is low, which will lead to problems such as low overall assembly yield and difficulty in rework.

[0046] In addition, after the folding device has been used for a period of time, the mechanical properties of the torque mechanism will decay. The usual after-sales practice is to dismantle and replace the entire torque mechanism, which will increase the after-sales cost and difficulty of maintenance.

[0047] In order to solve the above technical problems, the present application provides a folding device with adjustable torque. Figure 1-Figure 5 The folding device 1 provided in this embodiment includes a base assembly 10', a rotating member 20', a second cam member 22, an elastic member 23, a blocking member 24, and an adjustment mechanism 80. The base assembly 10' includes a base 10 and a rotating shaft 11 arranged on the base 10, and the axial direction of the rotating shaft 11 is assumed to be a sliding direction. The rotating member 20' is rotatably connected to the base 10, and a first cam member 21 is provided on the end side of the rotating member 20' along the sliding direction. The second cam member 22 is sleeved on the rotating shaft 11 and can cooperate with the first cam member 21, so that the second cam member 22 can slide along the sliding direction when the rotating member 20' rotates relative to the base 10. The elastic member 23 is sleeved on the rotating shaft 11 and one end abuts against the side of the second cam member 22 away from the first cam member 21, and the blocking member 24 is sleeved on the rotating shaft 11 and abuts against the other end of the elastic member 23. The adjusting mechanism 80 is disposed on the base 10 and connected to the blocking member 24 . The adjusting mechanism 80 can make the blocking member 24 slide along a sliding direction, thereby compressing or stretching the elastic member 23 .

[0048] The folding device 1 can also be called a rotating shaft or a hinge, and is mainly used in electronic products such as mobile phones, tablets, and computers, and can also be used in other non-electronic products that require a torque rotating shaft, such as doors and windows. The folding device 1 provided in this embodiment mainly includes a base assembly 10', a rotating member 20', a second cam member 22, an elastic member 23, a blocking member 24, and an adjusting mechanism 80, which means that this embodiment only uses the base assembly 10', the rotating member 20', the second cam member 22, the elastic member 23, the blocking member 24, and the adjusting mechanism 80 to solve the above-mentioned technical problems, but in other embodiments, the folding device 1 may also include other components, such as a connecting member 50, a rotating member 20', a synchronization mechanism, a torque mechanism, etc. Next, this embodiment will introduce the base assembly 10', the rotating member 20', the second cam member 22, the elastic member 23, the blocking member 24, and the adjusting mechanism 80 in detail.

[0049] The base assembly 10' is an assembly structure composed of a base 10 and a rotating shaft 11. The base 10 is the basic component of the folding device 1, and is mainly used to provide a foundation for the installation and fixation of other components, that is, many components of the folding device 1 can be installed on the base 10. When the folding device 1 moves, the base 10 itself is fixed, and it is mainly the other components of the folding device 1 that perform various movements. This embodiment does not limit the parameters such as the shape, structure, and material of the base 10, as long as it can provide an assembly foundation for other components. As for other components, they can cooperate with the sliding assembly to achieve the effect of increasing torque.

[0050] Optionally, the base 10 has a top surface, a bottom surface 100, and a side surface that is bent and connected between the top surface and the bottom surface 100. When the folding device 1 is subsequently applied to the electronic device 3, the top surface can be close to the flexible screen 93 of the electronic device 3, the bottom surface 100 is away from the flexible screen 93, and the bottom surface 100 can also cooperate with a shielding member to shield the base 10. In other words, the upper surface of the base 10 is the top surface, and the lower surface is the bottom surface 100. Further optionally, both the top surface and the bottom surface 100 are planes, which is convenient for subsequent cooperation with other components. The side surface is a convexly arranged arc surface, which improves the appearance of the base 10 and is convenient for cooperation with the shielding member.

[0051] The rotating shaft 11 can be disposed on the base 10 and also provide a mounting base for other components. For example, the second cam member 22, the elastic member 23, the blocking member 24 and other components can be sleeved on the rotating shaft 11 to achieve various movements, such as sliding and rotating. When the components slide on the rotating shaft 11, the sliding direction is parallel to the axial direction of the rotating shaft 11. Therefore, in this embodiment and the following, the axial direction of the rotating shaft 11 is set as the sliding direction (such as Figure 1(as shown in D in the figure). This embodiment does not limit the shape, structure, material and other parameters of the rotating shaft 11, as long as other components can be mounted thereon. Optionally, the rotating shaft 11 and the base 10 can be an integrated structure or a split structure. This embodiment only schematically illustrates the rotating shaft 11 and the base 10 as a split structure. Further optionally, the rotating shaft 11 can be fixed relative to the base 10, or the rotating shaft 11 itself can rotate relative to the base 10. This embodiment only schematically illustrates the rotating shaft 11 being fixed relative to the base 10.

[0052] The rotating member 20' mainly plays a role of rotation in the folding device 1, so that the folding device 1 has the ability to fold and unfold, and the rotation of the rotating member 20' drives and limits the movement of other components, so that other components move according to a predetermined trajectory. One end of the rotating member 20' is rotatably connected to the base 10 so that the rotating member 20' can rotate relative to the base 10, and the other end of the rotating member 20' can be subsequently connected to other components such as the connecting member 50. This embodiment does not limit the shape, structure, material and other parameters of the rotating member 20', as long as it can be rotatably connected to the base 10.

[0053] The rotation of the rotating member 20' enables the folding device 1 to have a variety of different states, such as an unfolded state and a folded state, wherein the unfolded state can be understood as the state when the rotating member 20' is completely flattened, at which time the other end of the rotating member 20' is set corresponding to the side of the base 10, so that the upper surface of the subsequent support member 60 can be set horizontally, thereby fully unfolding the flexible screen 93. The folded state can be understood as the state when the rotating member 20' is completely folded, at which time the other end of the rotating member 20' is set corresponding to the top surface of the base 10, so that the opposite ends of the subsequent flexible screen 93 can be close to each other, and the flexible screen 93 reaches a fully folded state. And the process of the folding device 1 from the unfolded state to the folded state can be understood as the folding process of the folding device 1, and the process of the folding device 1 from the folded state to the unfolded state can be understood as the unfolding process of the folding device 1.

[0054] Optionally, the rotating member 20 ′ may be directly rotatably connected to the base 10 itself, or the rotating member 20 ′ may be sleeved on the rotating shaft 11 to achieve indirect rotatable connection with the base 10 . This embodiment is only schematically described with the rotating member 20 ′ sleeved on the rotating shaft 11 .

[0055] Please refer again Figure 1In this embodiment, there can be two rotating shafts 11 and two rotating members 20', that is, the folding device 1 includes two rotating members 20' and two rotating shafts 11. The two rotating shafts 11 are arranged on opposite sides of the base 10, that is, one rotating shaft 11 is arranged on the left side of the base 10, and the other rotating shaft 11 is arranged on the right side of the base 10. Optionally, the two rotating shafts 11 are arranged axially symmetrically with respect to the base 10. Each rotating member 20' is fixed to a rotating shaft 11, that is, one rotating member 20' is sleeved on one rotating shaft 11, and the other rotating member 20' is sleeved on the other rotating shaft 11, so that the two rotating shafts 11 can be used to control the components on the left and right sides of the base 10 to unfold and fold respectively. Optionally, the two rotating shafts 11 and the two rotating members 20' are arranged axially symmetrically with respect to the base 10.

[0056] In this embodiment, the two second cam members 22 can be simultaneously sleeved on the two rotating shafts 11 and connected to each other. In this way, when the rotating member 20' rotates, the two first cam members 21 of the two rotating members 20' cooperate with the two second cam members 22. Since the two cam members are connected together and sleeved on the two rotating shafts 11, the second cam members 22 cannot move relative to the two rotating shafts 11 and can only slide relative to the rotating shafts 11.

[0057] In the related art, a torque mechanism is usually provided to provide torque to the rotating member 20', so as to improve the stability of the rotating member 20', and even enable the rotating member 20' to have a hovering function. For example, the rotating member 20' is provided with a first cam member 21 along the end side of its axial direction, and a second cam member 22, an elastic member 23, and a blocking member 24 are sleeved on the rotating shaft 11, and the second cam member 22 cooperates with the first cam member 21, and one end of the elastic member 23 abuts against the second cam member 22, and the other end abuts against the blocking member 24. The elastic member 23 is initially in a compressed state, providing a certain pre-pressure, so that the first cam member 21 and the second cam member 22 fit closely. Optionally, the elastic member 23 includes but is not limited to a spring.

[0058] The rotating shaft 11 makes the movement centers of the rotating member 20', the first cam member 21, the second cam member 22, the elastic member 23, and the base 10 coincide. In this way, when the rotating member 20' rotates around the rotating axis relative to the base 10, the cam surface of the first cam member 21 and the cam surface of the second cam member 22 mesh with each other, causing one end of the elastic member 23 to slide in a direction away from the rotating member 20'. However, since the blocking member 24 remains stationary, the other end of the elastic member 23 is also stationary, and finally the elastic member 23 is gradually compressed, thereby using the rebound force of the elastic member 23 in a compressed state to provide positive pressure between the first cam member 21 and the second cam member 22. The cam surfaces of the first cam member 21 and the second cam member 22 squeeze each other to increase the friction between the first cam member 21 and the second cam member 22, thereby increasing the torque of the rotating member 20' in the folding device 1. In other words, the torque required for the rotation of the rotating member 20' is basically the friction generated by the elastic member 23 squeezing the parts during the rotation process, so the force value that the elastic member 23 can provide plays a crucial role. Therefore, it can be found that the compression state or compression amount of the elastic member 23 in the related art always remains fixed, so the torque provided by the elastic member 23 to the rotating member 20' also remains fixed and cannot be changed. For example, it is impossible to change the sliding distance of the second cam member 22 when the first cam member 21 and the second cam member 22 cooperate to affect the compression amount of the elastic member 23, and it is also impossible to change the initial state of the elastic member 23.

[0059] This embodiment can add an adjustment mechanism 80 on the basis of the related art. The adjustment mechanism 80 is mainly used to adjust the torque of the folding device 1 by adjusting the compression length of the assembled elastic member 23. The adjustment mechanism 80 can be a single component or a combination of multiple components, as long as it can control the elastic member 23. The adjustment mechanism 80 can be connected to the blocking member 24 while being installed on the base 10, so that the adjustment mechanism 80 can control the movement of the blocking member 24.

[0060] In this embodiment, the adjustment mechanism 80 can make the blocking member 24 slide along the sliding direction. Since the blocking member 24 abuts against the other end of the elastic member 23, the blocking member 24 can drive the other end of the elastic member 23 to slide along the sliding direction. Since one end of the elastic member 23 abuts against the second cam member 22, the second cam member 22 cooperates with the first cam member 21 on the rotating member 20', so that when the other end of the elastic member 23 slides, it will not drive one end of the elastic member 23 to slide. One end of the elastic member 23 remains fixed, so that the elastic member 23 is compressed or stretched, thereby changing the initial state of the elastic member 23. For example, when the adjustment mechanism 80 makes the blocking member 24 slide in the direction close to the second blocking member 24, the other end of the elastic member 23 slides along the end close to the elastic member 23, so that the elastic member 23 is compressed. When the adjustment mechanism 80 makes the blocking member 24 slide in the direction away from the second blocking member 24, the other end of the elastic member 23 slides along the end away from the elastic member 23, so that the elastic member 23 is stretched. In other words, the present embodiment changes the initial elastic force of the elastic member 23 by changing the initial length of the elastic member 23 by using the adjustment mechanism 80, so that when the rotating member 20' rotates, the elastic member 23 gives different rebound forces to the second cam member 22 when it is compressed by the cooperation of the first cam member 21 and the second cam member 22: increase or decrease, thereby changing the torsion of the rotating member 20' in the folding device 1. For example, when the adjustment mechanism 80 compresses the elastic member 23, the initial elastic force of the elastic member 23 is increased, so when the rotating member 20' rotates by the same angle, the rebound force of the elastic member 23 given to the second cam member 22 is greater, and the torsion of the rotating member 20' is greater. When the adjustment mechanism 80 stretches the elastic member 23, the initial elastic force of the elastic member 23 is reduced, so when the rotating member 20' rotates by the same angle, the rebound force of the elastic member 23 given to the second cam member 22 is smaller, and the torsion of the rotating member 20' is smaller.

[0061] The “stretching” mentioned above does not refer to the process of the elastic member 23 changing from the equilibrium state to the stretched state, but refers to the process of the elastic member 23 becoming longer. Therefore, even if the elastic member 23 is originally in a compressed state, the elastic member 23 is still in a compressed state after the length is extended, which can also be called the stretching of the elastic member 23. Similarly, compression refers to the process of the elastic member 23 becoming shorter.

[0062] In summary, the present embodiment utilizes the adjustment mechanism 80 and the blocking member 24 to compress or stretch the elastic member 23, thereby changing the initial state of the elastic member 23, thereby changing the rebound force given by the elastic member 23 to the second cam member 22, and further changing the torque of the rotating member 20' in the folding device 1. In other words, the folding device 1 provided in the present embodiment can be adjusted for torque without disassembling parts, and can also be assembled with folding devices 1 of different torque values ​​by adjusting the compression value of the elastic member without replacing parts, so as to achieve adjustable torque to meet the needs of different user groups. And when the mechanical properties of the elastic member 23 decay after the folding device 1 has been used for a period of time, the adjustment mechanism 80 can be used to readjust the torque of the folding device 1, thereby avoiding the need to replace the entire torque mechanism, and reducing the difficulty and cost of maintenance.

[0063] Please refer again Figure 4 In this embodiment, the adjustment mechanism 80 abuts against the blocking member 24, and the adjustment mechanism 80 can slide in the sliding direction. When the adjustment mechanism 80 slides in the direction close to the second cam member 22, the adjustment mechanism 80 drives the blocking member 24 and the other end of the elastic member 23 to slide in the direction close to the second cam member 22, thereby compressing the elastic member 23. When the adjustment mechanism 80 slides in the direction away from the second cam member 22, the elastic member 23 in the compressed state stretches and drives the blocking member 24 to slide in the direction away from the second cam member 22, thereby abutting against the adjustment mechanism 80.

[0064] In this embodiment, the adjusting mechanism 80 can be supported on the blocking member 24, and the adjusting mechanism 80 itself can slide in the sliding direction. In this way, when the adjusting mechanism 80 slides in the direction close to the second cam member 22, the adjusting mechanism 80 drives the blocking member 24 and the other end of the elastic member 23 to slide in the direction close to the second cam member 22, thereby compressing the elastic member 23. However, when the adjusting mechanism 80 slides in the direction away from the second cam member 22, since the adjusting mechanism 80 only supports the blocking member 24, the adjusting mechanism 80 will not drive the blocking member 24 to move away synchronously when moving away. However, the other end of the elastic member 23 in the compressed state will stretch and drive the blocking member 24 to slide in the direction away from the second cam member 22, thereby re-supporting the adjusting mechanism 80. In other words, the adjusting mechanism 80 can compress the elastic member 23, and the adjusting mechanism 80 cooperates with the elastic member 23 to stretch the elastic member 23, thereby adjusting the initial state of the elastic member 23, and then adjusting the torque.

[0065] In other embodiments, the adjustment mechanism 80 may also be fixed on the blocking member 24 , in which case the adjustment mechanism 80 may synchronously drive the blocking member 24 to compress and extend the elastic member 23 , without using the elastic member 23 to drive the blocking member 24 to move.

[0066] In other embodiments, the adjusting mechanism 80 is fixed as a whole, but the length of the adjusting mechanism 80 itself can be changed. For example, the adjusting mechanism 80 itself can be extended or shortened. When the adjusting mechanism 80 is extended, the blocking member 24 can be used to compress the elastic member 23. When the adjusting mechanism 80 is shortened, the elastic member 23 can be stretched and extended.

[0067] Please refer to Figure 2 , Figure 6-Figure 7 , Figure 6 It is a schematic diagram of the three-dimensional structure of the base, the adjustment mechanism, and the blocking member in one embodiment of the present application. Figure 7 It is an exploded schematic diagram of the base, the first adjusting member, and the second adjusting member in one embodiment of the present application. In this embodiment, the adjusting mechanism 80 includes a first adjusting member 81 and a second adjusting member 82. The first adjusting member 81 is rotatably connected to the base 10 and the rotation direction of the first adjusting member 81 is parallel to the sliding direction. The second adjusting member 82 is rotatably connected to the first adjusting member 81 and the rotation direction of the second adjusting member 82 is perpendicular to the sliding direction. One end of the second adjusting member 82 is arranged on the base 10, and the other end abuts against the side of the blocking member 24 away from the elastic member 23. Among them, when the first adjusting member 81 rotates relative to the base 10, the first adjusting member 81 cooperates with the second adjusting member 82 and causes the second adjusting member 82 to slide along the sliding direction.

[0068] The adjustment mechanism 80 may be composed of two adjustment members: a first adjustment member 81 and a second adjustment member 82. The first adjustment member 81 is rotatably connected to the base 10 and the rotation direction of the first adjustment member 81 is parallel to the sliding direction, and the second adjustment member 82 is rotatably connected to the first adjustment member 81 and the rotation direction of the second adjustment member 82 is perpendicular to the sliding direction. In other words, the rotation directions of the first adjustment member 81 and the second adjustment member 82 are opposite, so that the rotation of the first adjustment member 81 can drive the second adjustment member 82 to rotate, thereby causing the second adjustment member 82 to rotate perpendicular to the sliding direction. Optionally, the first adjustment member 81 and the second adjustment member 82 can both be gears, and the first adjustment member 81 and the second adjustment member 82 are tapered in size.

[0069] In addition, one end of the second adjusting member 82 can be set on the base 10, and the other end can be abutted against the side of the blocking member 24 away from the elastic member 23. In this way, when the first adjusting member 81 rotates relative to the base 10, since the second adjusting member 82 is also connected to the base 10 and the blocking member 24 at the same time, the second adjusting member 82 can eventually slide along the axial direction of the rotating shaft 11, and the compression length of the elastic member 23 can be adjusted through Huadong, thereby adjusting the extrusion force value of the elastic member 23 here.

[0070] Please refer again Figure 6In this embodiment, when the second adjusting member 82 slides along the sliding direction, one end of the second adjusting member 82 also slides relative to the base 10. After the second adjusting member 82 slides along the sliding direction, one end of the second adjusting member 82 can be fixed to the base 10 to prevent the elastic member 23 from causing the second adjusting member 82 to slide in a direction away from the second cam member 22.

[0071] When the first adjusting member 81 rotates, the second adjusting member 82 can be driven to slide as a whole. Therefore, in addition to the other end of the second adjusting member 82 sliding, one end of the second adjusting member 82 will also slide relative to the base 10, thereby adjusting the length of the elastic member 23, and then adjusting the torque value. When the torque value is adjusted, one end of the second adjusting member 82 can be fixed on the base 10, that is, the sliding of the second adjusting member 82 is limited. In this way, the elastic member 23 in a compressed state after the adjustment is completed can be prevented from sliding the second adjusting member 82 in a direction away from the second cam member 22 through the blocking member 24, so as to prevent the elastic member 23 from returning to the state when it is not adjusted. If further adjustment is required later, the fixing point of one end of the second adjusting member 82 and the base 10 can be destroyed, so that one end of the second adjusting member 82 can slide relative to the base 10 again, and then the adjustment is performed. After the adjustment is completed, one end of the second adjusting member 82 is fixed on the base 10 again.

[0072] Please refer again Figure 6-Figure 7 In this embodiment, the other end of the second adjusting member 82 is provided with a supporting portion 820 for supporting the blocking member 24, and the width of the supporting portion 820 is greater than the width of the other end of the second adjusting member 82 along the direction perpendicular to the sliding. The other end of the second adjusting member 82 may be provided with a supporting portion 820, and the supporting portion 820 is used to support the blocking member 24. Along the direction perpendicular to the sliding, the width of the supporting portion 820 may be greater than the width of the other end of the second adjusting member 82, thereby increasing the supporting area between the second adjusting member 82 and the blocking member 24, so that the second adjusting member 82 can better drive the supporting member to slide. Optionally, the shape of the supporting portion 820 includes but is not limited to a rectangular plate-like structure.

[0073] Please refer to Figure 6-Figure 8 , Figure 81 is a schematic diagram of the decomposition of part of the base body and the assembly in one embodiment of the present application.

[0074] The base 10 is composed of a base body 12 and an assembly part 13. The rotating part 20', the rotating shaft 11 and other components can be installed on the base body 12, and the assembly part 13 is used to assemble the newly added first assembly part 13 and the second assembly part 13. The assembly part 13 includes a first part 131, a second part 132, and a third part 133. The first part 131 is fixed to the base body 12. Optionally, the first part 131 can be fixed to the bottom surface 100 of the base body 12 by bonding, screw connection, snap connection, etc., and the first part 131 is located below the blocking member 24 and passes through the blocking member 24 from below the blocking member 24. The second part 132 is connected to the first part 131, and the extension direction of the second part 132 is the same as the extension direction of the first part 131, both of which are parallel to the axial direction of the rotating shaft 11. The third part 133 is bent and connected to the second part 132. The second portion 132 and the third portion 133 are disposed on a side of the blocking member 24 away from the base body 12, and the first portion 131, the second portion 132, and the third portion 133 are surrounded to form a receiving space 134 for installing the first adjusting member 81 and the second adjusting member 82. Optionally, the thickness of the second portion 132 and the third portion 133 is greater than the thickness of the first portion 131, so as to provide space for installing the first adjusting member 81 and the second adjusting member 82.

[0075] Please refer to Figure 7 and Fig. 9 , Fig. 91 is a schematic diagram of an assembly and a first adjusting member from another perspective in an embodiment of the present application. In this embodiment, the first adjusting member 81 can be rotatably connected to the second portion 132, and one end of the second adjusting member 82 is mounted on the third portion 133. For example, the first adjusting member 81 and the second portion 132 can be connected by the first rotating shaft 1320 and the rotating hole 812, the first rotating shaft 1320 is provided on one of the second portion 132 and the first adjusting member 81, and the rotating hole 812 is provided on the other of the second portion 132 and the first adjusting member 81. Specifically, the first adjusting member 81 includes a first gear 811, and the first gear 811 is provided with a rotating hole 812 at one end close to the second portion 132, and the second portion 132 is provided with a first rotating shaft 1320.

[0076] In this embodiment, one end of the first adjusting member 81 is rotatably connected to the base 10, and the other end is provided with a first rotating portion 813, and the first rotating portion 813 is used to cooperate with the second rotating portion of the auxiliary member, so that the first adjusting member 81 can rotate relative to the base 10. Specifically, a cross-shaped first rotating portion 813 is convexly provided at one end of the first gear 811 away from the second part 132, and the first rotating portion 813 can cooperate with the cross-shaped second rotating portion recessed on the rotation auxiliary member, so that the convex first rotating portion 813 is arranged in the recessed second rotating portion, and then the first adjusting member 81 can be rotated by rotating the auxiliary member, thereby reducing the difficulty of rotating the first adjusting member 81. In summary, in this embodiment, by using the auxiliary member, the first rotating portion 813 and the second rotating portion are respectively provided on the first adjusting member 81 and the auxiliary member, so that the auxiliary member controls the rotation of the first adjusting member 81.

[0077] Please refer again Figure 7 In this embodiment, the second adjusting member 82 includes a second gear 821 and two second rotating shafts 822 arranged at opposite ends of the second size. The second gear 821 is rotatably connected to the first gear 811. The two second rotating shafts 822 and the second gear 821 are arranged in an axial direction of the rotating shaft 11. One second rotating shaft 822 passes through the third part 133, so that the second adjusting member 82 can slide relative to the base 10, and the other second rotating shaft 822 is provided with a supporting portion 820. In addition, the first part 131 is provided with a supporting platform 135 perpendicular to the sliding direction, and the supporting portion 820 is supported on the supporting platform 135. A supporting platform 135 is provided at the portion of the first part 131 passing through the blocking member 24. In other words, the thickness of the portion of the first part 131 passing through the blocking member 24 is increased, and the increased portion is the supporting platform 135. The supporting portion 820 can be supported on the supporting platform 135, and the supporting portion 820 can slide on the supporting platform 135, thereby improving the supporting effect of the supporting portion 820. Furthermore, the support platform 135 can also be used to limit the blocking member 24 . When the blocking member 24 abuts against the side of the support platform 135 , the support member 60 can prevent the blocking member 24 from continuing to slide in a direction away from the second cam member 22 .

[0078] Please refer again Figure 2 In other embodiments, a limiting portion 110 is provided at the end of the rotating shaft 11 along the circumferential direction, and the blocking member 24 can abut against the limiting portion 110. When the blocking member 24 slides in a direction away from the second cam member 22, the blocking member 24 abuts against the limiting portion 110 to prevent the blocking member 24 from continuing to slide. Therefore, the present application can limit the movement of the blocking member 24 in a variety of ways.

[0079] Please refer again Figure 6-Figure 7 In this embodiment, the second portion 132 is provided with a snap-fit ​​groove 136 , and one end of the supporting portion 820 is provided in the snap-fit ​​groove 136 . When the second adjusting member 82 slides in a direction away from the second cam member 22 , the supporting portion 820 can abut against the groove wall of the snap-fit ​​groove 136 .

[0080] The second portion 132 may also be provided with a snap-fit ​​groove 136, and one end of the abutting portion close to the second portion 132 is disposed in the snap-fit ​​groove 136. When the second adjusting member 82 slides in a direction away from the second cam member 22, the abutting portion abuts against the groove wall of the snap-fit ​​groove 136, thereby limiting the second adjusting member 82 from sliding further in a direction away from the second cam member 22. Therefore, in this embodiment, the snap-fit ​​groove 136 may be used to limit the sliding position of the second adjusting member 82, thereby preventing the second adjusting member 82 from moving too far away.

[0081] Please refer to Figure 10-15 , Fig.10 This is a schematic diagram of the three-dimensional structure of the folding device in another embodiment of the present application when it is in an unfolded state. Fig.11 for Fig.10 An exploded view of the folding device is shown. Fig.12 for Fig.11 An exploded view of a track mechanism in a folding device is shown. Fig.13 for Fig.10 A front view of the folding device is shown. Fig.14 This is a schematic diagram of the three-dimensional structure of the folding device in another embodiment of the present application when it is in a folded state. Fig.15 for Fig.14The front view of the folding device shown. The folding device 1 provided in this embodiment also includes two first rotating members 30, two second rotating members 40, two connecting members 50, and two supporting members 60. The two first rotating members 30 are respectively rotatably connected to the opposite sides of the base 10, and the two second rotating members 40 are respectively rotatably connected to the opposite sides of the base 10. One of the first rotating member 30 and the second rotating member 40 located on the same side of the base 10 is rotatably connected to the connecting member 50, and the other is slidably connected to the connecting member 50. Each supporting member 60 is rotatably connected to one connecting member 50, and is slidably and rotatably connected to the other of the first rotating member 30 and the second rotating member 40. The rotating member 20' is at least one of the first rotating member 30 and the second rotating member 40.

[0082] The first rotating member 30, the second rotating member 40, and the connecting member 50 in the folding device 1 can be collectively referred to as a track mechanism 1b, which is mainly used to control the motion track of the supporting member 60, thereby controlling the cross-sectional shape of the flexible screen 93 in the subsequent folding state, ensuring better support for the flexible screen 93 without damaging the various layer structures in the flexible screen 93. Next, this embodiment will introduce the first rotating member 30, the second rotating member 40, the connecting member 50, and the supporting member 60 in detail.

[0083] The two first rotating members 30 in the folding device 1 mainly realize the folding function through their rotation ability, and through the rotation of the two first rotating members 30, the components connected with the two first rotating members 30 are driven and limited, so that these components move according to the predetermined motion trajectory. The two first rotating members 30 are rotatably connected to the base 10 in the base assembly 10' and the two first rotating members 30 are respectively arranged on the opposite sides of the base 10, that is, the two first rotating members 30 can rotate relative to the base 10. In other words, the two first rotating members 30 are rotatably connected to the base 10 at one end close to the base 10. Since the base 10 is fixed, only the two first rotating members 30 rotate. The opposite sides of the base 10 mentioned in this embodiment refer to the opposite sides along the width direction of the base 10, and the width direction can be understood as the arrangement direction of the two first rotating members 30. The opposite sides in this embodiment and the following can be understood in the same way. This embodiment does not limit the parameters such as the shape, structure, material, etc. of the first rotating member 30, as long as the first rotating member 30 can be rotatably connected to the base 10.

[0084] Optionally, the two first rotating members 30 are rotatably connected to the side of the base 10. Further optionally, in one embodiment, the two first rotating members 30 are arranged axially symmetrically with respect to the base 10. In another embodiment, the two first rotating members 30 are arranged non-axially symmetrically with respect to the base 10, in other words, the two first rotating members 30 have a partially overlapping area in the length direction of the folding device 1. This embodiment is only schematically described with the two first rotating members 30 being arranged axially symmetrically with respect to the base 10.

[0085] The second rotating member 40 has the same function as the first rotating member 30. In the folding device 1, the folding function is mainly achieved through its ability to rotate, and the components connected to the two second rotating members 40 are driven and limited by the rotation of the two second rotating members 40, so that these components move according to a predetermined motion trajectory. The two second rotating members 40 are respectively rotatably connected to the opposite sides of the base 10, and the two second rotating members 40 and the two first rotating members 30 are arranged at intervals along the length direction of the base 10. This not only simplifies the structure of the folding device 1, but also enables the second rotating member 40 and the first rotating member 30 to be better rotatably connected to the base 10. In other words, the two second rotating members 40 are rotatably connected to the base 10 at one end close to the base 10. Since the base 10 is fixed, only the two second rotating members 40 rotate. This embodiment does not limit the parameters such as the shape, structure, and material of the second rotating member 40, as long as the second rotating member 40 can be rotatably connected to the base 10.

[0086] Optionally, the two second rotating members 40 are rotatably connected to the side of the base 10. Optionally, in one embodiment, the two second rotating members 40 are arranged axially symmetrically with respect to the base 10, and in another embodiment, the two second rotating members 40 are arranged asymmetrically with respect to the base 10, in other words, the two second rotating members 40 have a partially overlapping area in the length direction of the folding device 1. This embodiment is only schematically described with the two second rotating members 40 being arranged axially symmetrically with respect to the base 10.

[0087] The connecting member 50 mainly serves to connect various components in the folding device 1. One of each first rotating member 30 and each second rotating member 40 is rotatably connected to a connecting member 50, and the other is slidably connected to a connecting member 50. That is, each first rotating member 30 is rotatably connected to a connecting member 50, and the side of each first rotating member 30 away from the base 10 is rotatably connected to the connecting member 50. In other words, the first rotating member 30 can rotate relative to the connecting member 50. And each second rotating member 40 is slidably connected to a connecting member 50, that is, the side of each second rotating member 40 away from the base 10 is slidably connected to the connecting member 50, which can also be understood as the second rotating member 40 can slide relative to the connecting member 50. Alternatively, each first rotating member 30 is slidably connected to the connecting member 50, and each second rotating member 40 is rotatably connected to the connecting member 50. In addition, the connecting member 50 is also used to connect the shell later, so that the connecting member 50 and the shell are fixed together, so that when the shell rotates, the connecting member 50 can be driven to rotate together. This embodiment does not limit the shape, structure, material and other parameters of the connecting member 50, as long as the connecting member 50 can realize rotational connection with one rotating member 20' and sliding connection with another rotating member 20'. This embodiment is only schematically described by rotatably connecting each first rotating member 30 with one connecting member 50 and sliding connection with each second rotating member 40 with one connecting member 50.

[0088] The support member 60 is mainly used to support the flexible screen 93 when the folding device 1 is subsequently applied to the electronic device 3, so as to control the folding shape of the flexible screen 93, so the support member 60 can also be called an inclined plate. Similarly, the bearing member 70 can also be called a middle plate, and the folding device 1 can include two inclined plates and a middle plate, so the folding device 1 can also be called a three-plate structure. Optionally, the flexible screen 93 can be bonded to the support member 60 by means of adhesive or the like, so that the shape of the flexible screen 93 is more natural during the bending process, the stress after bending is small, and the damage of the flexible screen 93 is reduced. Each support member 60 is arranged on a connecting member 50. Specifically, the support member 60 is rotatably connected to the connecting member 50, that is, the support member 60 can rotate relative to the connecting member 50, and the support member 60 slides and rotates to connect the other of the first rotating member 30 and the second rotating member 40. In other words, the support member 60 can rotate relative to the other of the first rotating member 30 and the second rotating member 40, and the support member 60 can also slide relative to the other of the first rotating member 30 and the second rotating member 40. This embodiment is only schematically described by taking the support member 60 as sliding and rotatingly connected to the second rotating member 40 .

[0089] The folding device 1 may further include a shielding member 71, which is disposed on the bottom surface 100 and the side surface of the base 10 to protect and cover the base 10 and other components so that the user cannot observe the inside of the folding device 1. The shielding member 71 may also cooperate with the housings on the left and right sides of the base 10 to form the appearance of the electronic device 3.

[0090] The folding device 1 provided in this embodiment can regard the first rotating member 30, the second rotating member 40, the connecting member 50, and the supporting member 60 on one side of the base 10 as a left module, and the first rotating member 30, the second rotating member 40, the connecting member 50, and the supporting member 60 on the other side of the base 10 as a right module. The left module and the right module can be symmetrically designed or asymmetrically designed.

[0091] The folding device 1 provided in this embodiment can form a track mechanism 1b with the base 10, two first rotating members 30, two second rotating members 40, and two connecting members 50. In one embodiment, the folding device 1 includes a track mechanism 1b, which is arranged on one side of the support member 60. In another embodiment, the folding device 1 includes two track mechanisms 1b, which are arranged on one side of the support member 60, and the two track mechanisms 1b are arranged along the extension direction of the support member 60. At this time, the support member 60 rotates to connect the two connecting members 50, and slides and rotates to connect the two second rotating members 40. In other embodiments, the folding device 1 includes three or more track mechanisms 1b, which are arranged on one side of the support member 60, and the three or more track mechanisms 1b are arranged along the extension direction of the support member 60. At this time, the support member 60 rotates to connect three or more connecting members 50, and slides and rotates to connect three or more second rotating members 40. This embodiment is only schematically described as the folding device 1 including three track mechanisms 1b and two support members 60. Of course, the solution of two track mechanisms 1b and the solution of one track mechanism 1b should also fall within the protection scope of this application.

[0092] The rotation mentioned above can be understood as the two parts being able to perform circular motion around the axis of rotation, with only a change in angle but no change in displacement. Sliding can be understood as the two parts being able to perform parallel motion, with only a change in displacement but no change in angle. The fact that the two parts can both slide and rotate means that the two parts have both a change in displacement and a change in angle, and this sliding and rotating can also be referred to as rolling. Therefore, the relationship between the support member 60 and the second rotating member 40 can also be referred to as the support member 60 rollingly connected to the second rotating member 40.

[0093] Based on the above connection relationship, it can be known that the folding device 1 provided in this embodiment is composed of 6 kinematic pairs on one side, specifically, the first rotating member 30 cooperates with the base 10 to form a rotating pair, the first rotating member 30 cooperates with the connecting member 50 to form a rotating pair, the second rotating member 40 cooperates with the base 10 to form a rotating pair, the second rotating member 40 cooperates with the connecting member 50 to form a sliding pair, the supporting member 60 cooperates with the second rotating member 40 to form a rolling pair, and the supporting member 60 cooperates with the connecting member 50 to form a rotating pair. Therefore, the total degree of freedom of the various components on one side to cooperate together is 3*4 (a total of 4 components on one side, such as 1 first rotating member 30, 1 second rotating member 40, 1 connecting member 50, and 1 supporting member 60)-2*5 (a total of 5 low pairs on one side, such as 1 sliding pair and 4 rotating pairs)-1*1 (a total of 1 high pair on one side, such as 1 rolling pair) = 1.

[0094] Therefore, when the folding device 1 moves, the movement trajectory and movement route of each component are unique. Specifically, when the folding device 1 is folded, the connecting member 50 rotates relative to the base 10, the first rotating member 30 and the second rotating member 40 also rotate relative to the base 10, the second rotating member 40 also slides relative to the connecting member 50, the second rotating member 40 also slides and rotates relative to the support member 60, and the support member 60 also rotates relative to the connecting member 50, and finally the two support members 60 are folded relative to each other. When the folding device 1 is unfolded, the connecting member 50 rotates relative to the base 10, the first rotating member 30 and the second rotating member 40 also rotate relative to the base 10, the second rotating member 40 also slides relative to the connecting member 50, the second rotating member 40 also slides and rotates relative to the support member 60, and the support member 60 also rotates relative to the connecting member 50, and finally the two support members 60 are unfolded relative to each other.

[0095] The movement process of the folding device 1 mentioned above has a variety of active and passive logical relationships, and the present application uses one specific movement process as an example to illustrate. When the folding device 1 is folded, that is, when the folding device 1 is in the process of changing from the unfolded state to the folded state, in other words, when the two connecting members 50 rotate relative to the base 10 and approach each other, since the first rotating member 30 and the second rotating member 40 are both rotated to connect the base 10, the connecting member 50 can drive the first rotating member 30 and the second rotating member 40 to rotate relative to the base 10. And in the process of the first rotating member 30 and the second rotating member 40 rotating, the second rotating member 40 can also slide relative to the connecting member 50, that is, the connecting member 50 can slide along the second rotating member 40, thereby changing the distance between the connecting member 50 and the base 10. When the connecting member 50 slides, since the support member 60 is arranged on the connecting member 50, the connecting member 50 can drive the support member 60 to slide together. When the support member 60 slides, the second rotating member 40 can also slide and rotate relative to the support member 60, thereby driving the support member 60 to rotate relative to the connecting member 50. Of course, in other embodiments, the support member 60 may not rotate relative to the connecting member 50 during the sliding and rotating process of the second rotating member 40, that is, the support member 60 and the connecting member 50 remain stationary, and finally the two support members 60 can be folded with each other.

[0096] Similarly, when the folding device 1 is unfolded, that is, when the folding device 1 is in the process of changing from the folded state to the unfolded state, in other words, when the two connecting members 50 rotate in the opposite direction relative to the base 10 and move away from each other, since the first rotating member 30 and the second rotating member 40 are both rotated to connect the base 10, the connecting member 50 can drive the first rotating member 30 and the second rotating member 40 to rotate relative to the base 10. In addition, during the rotation of the first rotating member 30 and the second rotating member 40, the second rotating member 40 can also slide relative to the connecting member 50, that is, the connecting member 50 can slide along the second rotating member 40, thereby changing the distance between the connecting member 50 and the base 10. When the connecting member 50 slides, since the support member 60 is disposed on the connecting member 50, the connecting member 50 can drive the support member 60 to slide together. When the support member 60 slides, the second rotating member 40 can also slide and rotate relative to the support member 60, thereby driving the support member 60 to rotate relative to the connecting member 50. Of course, in other embodiments, the support member 60 may not rotate relative to the connecting member 50 during the sliding and rotating process of the second rotating member 40, that is, the support member 60 and the connecting member 50 remain stationary, and finally the two support members 60 can be unfolded to each other.

[0097] In other embodiments, the active and passive relationships of the above-mentioned components can be reversed, for example, the support member 60 can rotate relative to the base 10 to drive the first rotating member 30, the second rotating member 40, and the connecting member 50 to rotate relative to the base 10. Such movement processes and principles should also fall within the protection scope of this application.

[0098] like Fig.13 As shown, when the two support members 60 are parallel to each other and are located on opposite sides of the base 10, the two support members 60 are in a state of being fully unfolded relative to each other. In other words, the folding device 1 is in an unfolded state. Fig.15 As shown in FIG. 1 , when the two support members 60 are both located on one side of the base 10, it can also be understood that the two support members 60 are both located on the top surface of the base 10. At this time, the two support members 60 are in a state of being completely folded with each other. In other words, the folding device 1 is in a folded state. When the two support members 60 are folded with each other, that is, the process of the folding device 1 from the unfolded state to the folded state can also be understood as the process from Figures 13 to 15 When the two support members 60 are unfolded from each other, that is, the process of the folding device 1 from the folded state to the unfolded state can also be understood as the process from Figure 15 to Figure 13 process.

[0099] like Fig.15 As shown, when the folding device 1 is in a folded state, the two support members 60 and the base 10 are jointly enclosed to form a screen space 1a for accommodating the flexible screen 93. The folding device 1 provided in this embodiment can make the cross-sectional shape of the screen space 1a U-shaped or teardrop-shaped. When the cross-sectional shape of the screen space 1a is U-shaped, the distance between the two support members 60 at the end away from the base 10 is equal to the distance between the two support members 60 at the end close to the base 10. At this time, the structure of the folding device 1 is simple and the reliability of the whole machine is high. When the cross-sectional shape of the screen space 1a is teardrop-shaped, the distance between the two support members 60 at the end away from the base 10 is less than the distance between the two support members 60 at the end close to the base 10. At this time, after folding, the whole folding device 1 is thinner and flat. This embodiment is only schematically illustrated with the cross-sectional shape of the screen space 1a being teardrop-shaped.

[0100] In addition, the rotating member 20' includes at least one of the first rotating member 30 and the second rotating member 40, that is, the first rotating member 30 can be the rotating member 20' mentioned above to cooperate with the sliding assembly, or the second rotating member 40 can be the rotating member 20' mentioned above to cooperate with the sliding assembly, or the first rotating member 30 and the second rotating member 40 can both be the rotating member 20' mentioned above to cooperate with the sliding assembly. In other words, the rotating member 20' mentioned above is a component of the first rotating member 30 and the second rotating member 40, but it is artificially named differently. This embodiment only schematically illustrates the rotating member 20' as the second rotating member 40, and in other embodiments, the rotating member 20' can also cooperate with the first rotating member 30.

[0101] The present application will now describe in detail the components that cooperate with each other. Since most components are two in number, this embodiment will only describe the components that cooperate with each other in detail. Fig.11 and Fig.12 The components on the right side of the base 10 in the folding device 1 are schematically illustrated, and the same understanding can be applied to the components on the left side of the base 10 .

[0102] Please refer to Fig.16 , Fig.16 It is a schematic diagram of the coordination of the base, the first rotating member, the second rotating member and the connecting member in one embodiment of the present application. In this embodiment, the first rotating axis C1 between the first rotating member 30 and the base 10 and the second rotating axis C2 between the second rotating member 40 and the base 10 are parallel to each other. The first rotating axis C1 is farther away from the bottom surface 100 of the base 10 than the second rotating axis C2, and when the folding device 1 is in the unfolded state, the first rotating axis C1 is farther away from the connecting member 50 than the second rotating axis C2. In other words, the first rotating axis C1 is higher and further to the left than the second rotating axis C2, so in Fig.16 In the figure, the first rotation axis C1 is located at the upper left, and the second rotation axis C2 is located at the lower right. The first rotating member 30 moves in the form of rotation, which determines the position of the connecting member 50 during the movement. The second rotating member 40 moves in the form of rotation and sliding, which determines the angle of the connecting member 50 during the movement. The position and angle of the connecting member 50 are determined by the mutual cooperation between the first rotating member 30 and the second rotating member 40.

[0103] Specifically, when the first rotating member 30 and the second rotating member 40 rotate, the connecting member 50 can slide in a direction away from the base 10 when the folding device 1 is folded, based on the sliding of the connecting member 50 relative to the second rotating member 40. When the folding device 1 is unfolded, the connecting member 50 slides in a direction close to the base 10, so that the supporting member 60 can further move according to a preset trajectory, so that when the folding device 1 is in a folded state, the folding device 1 forms a water drop-shaped screen space 1a. In this way, no matter whether the folding device 1 is folded or unfolded, when the connecting member 50 rotates relative to the base 10, the first rotating member 30 and the second rotating member 40 are also driven to rotate relative to the base 10, so that the connecting member 50 slides relative to the second rotating member 40, thereby changing the distance between the connecting member 50 and the base 10, driving the supporting member 60 rotatably connected to the connecting member 50 to slide relative to the second rotating member 40, changing the distance between the supporting member 60 and the base 10, and then realizing the subsequent movement process. In summary, in this embodiment, no new components need to be added, and the sliding of the connecting member 50 relative to the second rotating member 40 can be achieved only by designing the positions of the first rotating axis C1 and the second rotating axis C2 .

[0104] In this embodiment, the first rotating member 30 and the base 10 are connected by the first arc rail and the first arc groove. The first arc rail is provided on one of the first rotating member 30 and the base 10, and the first arc groove is provided on one of the first rotating member 30 and the base 10. For example, when the first arc rail is provided on the first rotating member 30, the first arc groove is provided on the base 10. When the first arc groove is provided on the first rotating member 30, the first arc rail is provided on the base 10. In this embodiment, the first arc rail is provided on the first rotating member 30 and the first arc groove is provided on the base 10 for schematic description. Specifically, a circular arc block is provided on one side of the first rotating member 30 close to the base 10, and the block is the first arc rail. The base 10 is provided with a protrusion, and an arc-shaped groove body is provided in the protrusion, and the groove body is the first arc groove. The first arc track is provided in the first arc groove, and the axis of the first arc groove is colinear with the axis of the first arc track, so that the first rotating member 30 can rotate relative to the base 10. In other words, the first rotating member 30 and the base 10 can be rotatably connected together through the arc slide rail and the arc slide groove.

[0105] As for the size and curvature of the first arc groove and the first arc track, they can be designed according to the position of the rotation axis between the first rotating member 30 and the base 10. The design of the first arc groove and the first arc track can make the position of the rotation axis inside the base 10 or outside the base 10. By adjusting the size and curvature of the first arc groove and the first arc track, the position of the rotation axis can be better designed, thereby achieving the above-mentioned positional relationship between the rotation axis and the rotation axis. Of course, in other embodiments, the first arc groove can also be provided on the first rotating member 30, and the first arc track can be provided on the base 10.

[0106] In summary, this embodiment can better adjust the position of the rotation axis by adopting the rotation connection scheme of the first arc groove and the first arc rail, so as to achieve the purpose of making the rotation axis parallel to each other, so that the first rotation axis C1 and the second rotation axis C2 meet the above position relationship. In addition, the matching form of the first arc groove and the first arc rail makes it possible to change the distance from the end of the first rotation member 30 away from the base 10 to the base 10 when the first rotation member 30 rotates relative to the base 10, thereby adjusting the distance between the first rotation member 30 and the base 10, and further achieving the purpose of controlling the sliding of the support member 60 relative to the base 10.

[0107] In this embodiment, the second rotating member 40 and the base 10 are connected by the first rotating shaft and the first rotating hole 812, the first rotating shaft is provided at one of the second rotating member 40 and the base 10, and the first rotating hole 812 is provided at the other of the second rotating member 40 and the base 10. Since the second rotating member 40 is rotatably connected to the base 10, the second rotating member 40 and the base 10 can be connected by the first rotating shaft and the first rotating hole 812 in this embodiment, the first rotating shaft is provided at one of the second rotating member 40 and the base 10, and the first rotating hole 812 is provided at the other of the second rotating member 40 and the base 10. For example, when the first rotating shaft is provided at the second rotating member 40, the first rotating hole 812 is provided at the base 10. When the first rotating hole 812 is provided at the second rotating member 40, the first rotating shaft is provided at the base 10. This embodiment is only schematically described by providing the first rotating shaft at the base 10 and the first rotating hole 812 at the second rotating member 40. Optionally, the first rotation axis includes but is not limited to the rotation axis 11 mentioned above.

[0108] From the above content, it can be known that since the first rotating member 30 and the base 10 can be matched through the first arc groove and the first arc track, the position of the rotation axis between the first rotating member 30 and the base 10 can be changed by designing the curvature and size of the first arc groove and the first arc track. Therefore, there is no need to change the position of the rotation axis between the second rotating member 40 and the base 10, and only the first rotating shaft and the first rotating hole 812 can be used to match, thereby simplifying the structure of the folding device 1.

[0109] In this embodiment, the first rotating member 30 and the connecting member 50 are connected by the second rotating shaft and the second rotating hole 812, the second rotating shaft is provided at one of the first rotating member 30 and the connecting member 50, and the second rotating hole 812 is provided at the other of the first rotating member 30 and the connecting member 50. Since the first rotating member 30 is rotatably connected to the connecting member 50, the first rotating member 30 and the connecting member 50 can be connected by the second rotating shaft and the second rotating hole 812 in this embodiment, the second rotating shaft is provided at one of the first rotating member 30 and the connecting member 50, and the second rotating hole 812 is provided at the other of the first rotating member 30 and the connecting member 50. For example, when the second rotating shaft is provided at the first rotating member 30, the second rotating hole 812 is provided at the connecting member 50. When the second rotating hole 812 is provided at the first rotating member 30, the second rotating shaft is provided at the connecting member 50. This embodiment is only schematically described by providing the second rotating shaft at the connecting member 50 and the second rotating hole 812 at the first rotating member 30. Optionally, the second rotation axis includes but is not limited to a pin.

[0110] From the above content, it can be known that when the connecting member 50 rotates relative to the base 10 and drives the first rotating member 30 and the second rotating member 40 to rotate relative to the base 10, the connecting member 50 will also slide relative to the second rotating member 40. Therefore, the distance between the connecting member 50 and the base 10 will change, and the distance between the connecting member 50 and the first rotating member 30 will also change. However, since the first rotating member 30 is rotatably connected to the base 10, the first rotating member 30 cannot move. Therefore, in order to avoid interference during movement, the first rotating member 30 can be rotatably connected to the connecting member 50. When the connecting member 50 slides relative to the second rotating member 40, the first rotating member 30 also rotates relative to the connecting member 50 to compensate for the distance when the connecting member 50 slides, ensuring the smoothness of the movement of the folding device 1.

[0111] Please refer to Fig.12 and Fig.17 , Fig.17 The figure is an exploded schematic diagram of the base, the second rotating member, and the connecting member in one embodiment of the present application. In this embodiment, the second rotating member 40 and the connecting member 50 are connected by a sliding block 42 and a sliding groove 52, the sliding block 42 is provided at one of the second rotating member 40 and the connecting member 50, and the sliding groove 52 is provided at the other of the second rotating member 40 and the connecting member 50. The connecting member 50 has a back surface 500 for facing away from the flexible screen 93, and the distance between the end of the sliding block 42 close to the base 10 and the back surface 500 is smaller than the distance between the end of the sliding block 42 away from the base 10 and the back surface 500.

[0112] The sliding block 42 is not arranged horizontally but inclined, and the farther the sliding block 42 is from the base 10, the greater the distance between the sliding block 42 and the back 500. Since the sliding block 42 is arranged inclined, the sliding groove 52 is also arranged inclined to match the sliding block 42, and the distance between the end of the sliding groove 52 close to the base 10 and the back 500 is smaller than the distance between the end of the sliding groove 52 away from the base 10 and the back 500. When the folding device 1 is changed from the unfolded state to the folded state, the connecting member 50 slides relative to the second rotating member 40 in the direction away from the base 10. By designing the shapes of the sliding block 42 and the sliding groove 52, not only can the supporting member 60 be further moved according to the preset trajectory, but also when the folding device 1 is in the folded state, the folding device 1 forms a water drop-shaped screen space 1a. When the two connecting members 50 slide in the direction away from the base 10, the two connecting members 50 also approach each other, so that when the folding device 1 is in the folded state, the distance between the two connecting members 50 can be reduced, and the thickness of the folding device 1 in the folded state can be reduced. The two opposite ends of the flexible screen 93 can also be made to abut against each other, thereby eliminating the gap between the two ends of the flexible screen 93 when in the folded state, thereby improving the safety performance of the flexible screen 93 and improving the appearance effect.

[0113] Please refer to Figure 18-Figure 20, Fig.18 It is a schematic diagram of the exploded view of the second rotating member and part of the supporting member in one embodiment of the present application. Fig.19 It is a cross-sectional schematic diagram of the base, the second rotating member, and the supporting member when the folding device is in an unfolded state in one embodiment of the present application. Fig. 20 The cross-sectional schematic diagram of the base, the second rotating member, and the supporting member when the folding device is in the folded state in one embodiment of the present application. In this embodiment, the supporting member 60 includes a supporting portion 61 and a rolling portion 62. The supporting portion 61 has a supporting surface 610 for supporting the flexible screen 93. The rolling portion 62 is arranged on the side of the supporting portion 61 away from the supporting surface 610. The second rotating member 40 and the rolling portion 62 are connected by a first rolling shaft 43 and a first rolling groove 620. The first rolling shaft 43 is arranged on one of the second rotating member 40 and the rolling portion 62, and the first rolling groove 620 is arranged on the other of the second rotating member 40 and the rolling portion 62. The first rolling groove 620 has a first limiting end 621 and a second limiting end 622 arranged opposite to each other. The first limiting end 621 is farther away from the base 10 than the second limiting end 622, and the first limiting end 621 is farther away from the supporting surface 610 than the second limiting end 622. When the folding device 1 is in the unfolded state, the first rolling shaft 43 is positioned at the first limit end 621 , and when the folding device 1 is in the folded state, the first rolling shaft 43 is positioned at the second limit end 622 .

[0114] The first limit end 621 is farther from the base 10 than the second limit end 622, and the first limit end 621 is farther from the support surface 610 than the second limit end 622. In other words, the first limit end 621 is further to the right and lower than the second limit end 622, that is, the first limit end 621 is located at the lower right position, and the second limit end 622 is located at the upper left position. During the movement of the folding device 1, when the folding device 1 is in the unfolded state, the first rolling axis 43 is positioned at the first limit end 621 to prevent the support member 60 from folding back and damaging the subsequent flexible screen 93. When the folding device 1 is in the folded state, the first rolling axis 43 is positioned at the second limit end 622 to prevent the support member 60 from folding back and damaging the subsequent flexible screen 93. It can also be understood that when the folding device 1 is in the unfolded state, the first rolling axis 43 is located at the lower right, and when the folding device 1 is in the folded state, the first rolling axis 43 is located at the upper left.

[0115] The first rolling groove 620 also has a first connecting portion 623 connecting the first limiting end 621 and the second limiting end 622. The first connecting portion 623 protrudes in the direction away from the support surface 610, so that the position of the first rolling shaft 43 in the first rolling groove 620 can be controlled during the entire movement process, thereby controlling the positional relationship between the rotation axis between the support member 60 and the connecting member 50 and the first rolling shaft 43, so that the support member 60 rotates to form a teardrop shape in the folded state. In addition, the arc-shaped first rolling groove 620 can also make the rolling of the first rolling shaft 43 smoother, thereby improving the smoothness and stability of the movement of the folding device 1. Of course, in other embodiments, the shape of the first connecting portion 623 can also be a straight line, or other shapes, as long as the positions of the first limiting end 621 and the second limiting end 622 meet the above-mentioned positional relationship.

[0116] The first rolling groove 620 also has a second connecting portion 624 connecting the first connecting portion 623 and the first limiting end 621, and the extension direction of the second connecting portion 624 is parallel to the support surface 610. In the process of the folding device 1 from the unfolded state to the folded state, the first rolling shaft 43 does not move directly from the first limiting end 621 to the second connecting portion 624, but first moves to the second connecting portion 624 and then moves to the first connecting portion 623. In this way, when the folding device 1 is in the unfolded state, the horizontal second connecting portion 624 can be used to support the first rolling shaft 43, and the second connecting portion 624 can be used to achieve buffering, so as to prevent the first rolling shaft 43 from moving from the first limiting end 621 to the arc-shaped first connecting portion 623 by itself, thereby improving the stability of the folding device 1. In addition, the horizontally arranged second connecting portion 624 can also reduce the gap between the first rolling shaft 43 and the first rolling groove 620 to prevent the existence of a virtual position.

[0117] In this embodiment, the support member 60 and the connecting member 50 are connected by the third arc rail and the third arc groove, the third arc rail is provided at one of the support member 60 and the connecting member 50, and the third arc groove is provided at the other of the support member 60 and the connecting member 50. Since the support member 60 is rotatably connected to the connecting member 50, the support member 60 and the connecting member 50 can be connected by the third arc rail and the third arc groove in this embodiment, the third arc rail is provided at one of the support member 60 and the connecting member 50, and the third arc groove is provided at the other of the support member 60 and the connecting member 50. For example, when the third arc rail is provided at the support member 60, the third arc groove is provided at the connecting member 50. When the third arc groove is provided at the support member 60, the third arc rail is provided at the connecting member 50. This embodiment is only schematically described with the third arc groove provided at the support member 60 and the third arc rail provided at the connecting member 50.

[0118] Specifically, the support member 60 includes a support portion 61 and a rotating portion, wherein the support portion 61 is used to support the flexible screen 93 when the folding device 1 is applied to the electronic device 3. Therefore, the support portion 61 has a support surface 610 for supporting the flexible screen 93, that is, the upper surface of the support portion 61 is the support surface 610. The rotating portion is arranged on the side of the support portion 61 away from the support surface 610, that is, the rotating portion is farther away from the flexible screen 93 than the support portion 61. A circular arc groove is provided on the side of the rotating portion close to the connecting member 50, and the groove is the third circular arc groove. A circular arc block is provided on the side of the connecting member 50 close to the rotating portion, and the block is the third circular arc rail. The third circular arc rail can be arranged in the third circular arc groove, and the axis of the third circular arc groove is colinear with the axis of the third circular arc rail, so that the rotating portion of the support member 60 can rotate relative to the connecting member 50. As for the size and curvature of the third circular arc groove and the third circular arc rail, they can be designed according to the position of the rotation axis between the support member 60 and the connecting member 50. In addition, it can be known from the above content that in this embodiment, the support member 60 can be rotated relative to the connecting member 50 by changing the position between the rotation axis and the rolling axis between the support member 60 and the connecting member 50. Therefore, the design of the circular arc groove and the circular arc track can make the position of the rotation axis inside the connecting member 50 or outside the connecting member 50, and the position and shape of the rolling axis and the rolling groove can be better designed by adjusting the size and curvature of the third circular arc groove and the third circular arc track, so that the support member 60 can be rotated relative to the connecting member 50. Of course, in other embodiments, the third circular arc track can also be provided on the support member 60, and the third circular arc groove can also be provided on the connecting member 50.

[0119] Optionally, in one embodiment, the connecting member 50 may have a third circular arc track, which is disposed on one side of the connecting member 50. Correspondingly, the supporting member 60 has a rotating portion and a third circular arc groove. In another embodiment, the connecting member 50 may have two third circular arc tracks, which are disposed on opposite sides of the connecting member 50. Correspondingly, the supporting member 60 has two rotating portions and a third circular arc groove. This embodiment is only schematically described by taking the connecting member 50 having two third circular arc tracks and the supporting member 60 having two third circular arc grooves.

[0120] In this embodiment, the connection member 50 and the support member 60 are connected by a constraint shaft and a constraint hole. The constraint shaft is provided on one of the connection member 50 and the support member 60, and the constraint hole is provided on the other of the connection member 50 and the support member 60. When the constraint shaft is provided on the connection member 50, the constraint hole is provided on the support member 60. When the constraint hole is provided on the connection member 50, the constraint shaft is provided on the support member 60. In this embodiment, the constraint shaft is provided on the connection member 50 and the constraint hole is provided on the support member 60 for schematic illustration. Specifically, a cylindrical column is provided at the end of the connection member 50, and the column is the constraint shaft. The support member 60 includes a support portion 61 and a constraint portion fixed to the support portion 61 and facing away from the support surface 610. A groove is provided on the side of the constraint portion facing the constraint shaft, and the groove is the constraint groove. The constraint shaft can be inserted into the constraint groove so that the connection member 50 and the support member 60 can be constrained. Of course, in other embodiments, the constraint shaft can also be provided on the support member 60, and the constraint hole can also be provided on the connection member 50.

[0121] The constraint axis and the constraint hole can cooperate with each other to prevent the folding device 1 from having movement deviation during movement, causing the support member 60 to rotate excessively relative to the first rotating member 30 and warp, which subsequently affects the folding of the flexible screen 93. In other words, this embodiment limits the movement trajectory of the inclined plate by adding a virtual constraint between the first rotating member 30 and the second rotating member 40, but the constraint axis and the constraint hole do not affect the degree of freedom of the folding device 1.

[0122] In summary, the folding device 1 provided in this embodiment can ultimately control the movement trajectory of the support member 60 through the mutual cooperation of the first rotating member 30, the second rotating member 40, and the connecting member 50 to obtain the screen space 1a of the shape required by the user.

[0123] Please refer to Figure 21-22 , Fig.21 It is a schematic diagram of the three-dimensional structure of the shell assembly in an embodiment of the present application when it is in an unfolded state. Fig. 22 The 3D schematic diagram of the housing assembly in a folded state in one embodiment of the present application. The housing assembly 2 provided in this embodiment includes a first housing 91, a second housing 92, and a folding device 1 provided in the above embodiment of the present application, and the folding device 1 is connected between the first housing 91 and the second housing 92.

[0124] The housing assembly 2 is a combined component, that is, the housing assembly 2 includes at least two components. In this embodiment, the housing assembly 2 mainly includes two housings and the folding device 1 provided in the above embodiment of the present application. The first housing 91 and the second housing 92 are mainly used to install and carry components. For example, a flexible screen 93 can be carried on the first housing 91 and the second housing 92, and functional modules such as batteries, PCB components, speakers, receivers, buttons, etc. can be set in the first housing 91 and the second housing 92. Therefore, the first housing 91 and the second housing 92 mainly play the role of installation and protection. In some embodiments, the surface of the first housing 91 and the second housing 92 can also serve as an appearance surface, so the surface of the first housing 91 and the second housing 92 can be designed accordingly, so that the first housing 91 and the second housing 92 have a unique appearance effect. This embodiment does not limit the parameters such as the shape, material, structure, etc. of the first housing 91 and the second housing 92, as long as the installation and protection functions can be achieved. For example, the material of the first housing 91 and the second housing 92 can be all metal, or all plastic, or partly metal and partly plastic.

[0125] One connecting member 50 of the folding device 1 is connected to the first shell 91, and the other connecting member 50 is connected to the second shell 92, so that when the first shell 91 and the second shell 92 rotate, the two connecting members 50 are driven to rotate relative to the base 10, thereby realizing the subsequent movement process. For example, the movement of the first rotating member 30, the second rotating member 40, and the supporting member 60, and the relative movement of the first moving member and the second moving member provide damping for the movement of the shell assembly 2. Optionally, the shell and the connecting member 50 can be fixed by screws, buckles, or glue.

[0126] The shell assembly 2 provided in this embodiment can adjust the torque value of the shell assembly 2 without disassembling or replacing parts by adopting the folding device 1 provided in the above-mentioned embodiment of the present application.

[0127] Please refer to Figure 23-Figure 24 , Fig.23 It is a schematic diagram of the three-dimensional structure of the electronic device 3 in an expanded state according to one embodiment of the present application. Fig.24 The three-dimensional structure diagram of the electronic device 3 in an embodiment of the present application when it is in a folded state. The electronic device 3 provided in this embodiment includes a flexible screen 93 and a housing assembly 2 as provided in the above embodiment of the present application, and the flexible screen 93 is arranged on the same side of the first housing 91, the second housing 92, and the folding device 1.

[0128] The electronic device 3 provided in this embodiment includes but is not limited to mobile terminals such as mobile phones, tablet computers, laptop computers, PDAs, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers. The mobile phone is used as an example for schematic illustration.

[0129] The electronic device 3 includes a flexible screen 93 and a shell assembly 2. The flexible screen 93 is a component with a certain flexibility. Compared with a rigid component, the flexible screen 93 can be bent to a certain extent. For example, the flexible screen 93 includes but is not limited to various flexible components with corresponding functions such as a flexible display screen, a flexible touch screen, and a flexible touch display screen, or a flexible component fixedly bonded with a flexible support plate, such as a flexible display screen and a flexible touch screen bonded with a flexible steel plate. The flexible screen 93 is arranged on the same side of the first shell 91 and the second shell 92 in the shell assembly 2, and can be bent or flattened with the shell assembly 2. Specifically, the flexible screen 93 has a bending area 930 and non-bending areas 931 arranged on opposite sides of the bending area 930. The bending area 930 corresponds to the middle plate setting of the bonding and folding device 1, and the non-bending area 931 is fixed to the first shell 91 and the second shell 92. Since the flexible screen 93 in the bending area 930 is correspondingly attached to the middle plate of the folding device 1, the shape of the folding device 1 changes when it moves, so it can drive the flexible screen 93 in the bending area 930 to bend as well, thereby bending or flattening with the movement of the electronic device 3. Since the non-bending area 931 is fixed on the first shell 91 and the second shell 92, the first shell 91 and the second shell 92 can only rotate relative to each other, and the shape itself will not change. Therefore, even if the first shell 91 and the second shell 92 rotate, the flexible screen 93 on the first shell 91 and the second shell 92 will not bend.

[0130] The electronic device 3 provided in this embodiment adopts the housing assembly 2 provided in the above-mentioned embodiment of the present application, and can adjust the torque value of the housing assembly 2 without disassembling or replacing parts.
