Description

Technical Field

[0001] The present application belongs to the technical field of electronic products, and specifically relates to electronic equipment. 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. However, the flexible screens of current electronic devices will produce creases when bent statically or repeatedly. Summary of the invention

[0003] In view of this, the present application provides an electronic device, including:

[0004] Folding device;

[0005] Two housing components, respectively connected to opposite sides of the folding device;

[0006] A flexible screen is fixed to the two housing components; and

[0007] Two elastic members, opposite ends of each of the elastic members respectively abut against the folding device and one of the housing components;

[0008] Wherein, when the electronic device is in an unfolded state or a folded state, the elastic member is in a compressed state.

[0009] The shell assembly in the electronic device provided by the present application is connected to the opposite sides of the folding device, and then an elastic member is added so that one end of each elastic member abuts against the folding device, and the other end abuts against the shell assembly. And no matter when the electronic device is in the unfolded state or the folded state, the elastic member is in a compressed state, that is, when the electronic device moves, the elastic member is always in a compressed state. The elastic member in the compressed state can use its elastic force to push the shell assembly to move outward relative to the folding device, in other words, the shell assembly has the ability to move in a direction away from the folding device. Since the two ends of the flexible screen are fixed on the shell assembly, the two shell assemblies pull the two ends of the flexible screen outward respectively under the action of the elastic member. The flexible screen is straightened under the action of the pulling force at both ends, thereby reducing the creases of the flexible screen and improving the display performance and service life of the flexible screen.

DETAILED DESCRIPTION

[0050] 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.

[0051] As the market demand for the "display area" of mobile terminal products makes the industry competition increasingly tend to large screens and ultra-thin, 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 a flexible screen, from a small screen to a large screen, and from a static mechanism to a moving mechanism. Foldable electronic devices are popular among users because the display screen of the electronic device can be folded and can be unfolded or closed, resulting in a larger display area when unfolded and a smaller overall size when folded. Recently, major manufacturers have been developing folding screens, etc., 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.

[0052] Compared with traditional rigid display screens, foldable electronic devices mainly use flexible screens. The opposite ends of the flexible screen are fixed on two shells respectively, and the flexible screen can be unfolded and folded under the drive of the two shells. However, since the flexible screen is made of multiple functional layers with different structures, the flexible screen will have creases due to the changes in the internal layers during the continuous bending process. The creases will not only affect the display performance of the flexible screen, but also reduce the service life of the flexible screen.

[0053] Please refer to Figure 1-Figure 9 The electronic device 1 provided in this embodiment includes a folding device 2, two housing components 3, a flexible screen 90, and two elastic members 4. The two housing components 3 are respectively connected to opposite sides of the folding device 2. The flexible screen 90 is fixed to the two housing components 3. The opposite ends of each elastic member 4 are respectively against the folding device 2 and a housing component 3. When the electronic device 1 is in an unfolded state or a folded state, the elastic members 4 are in a compressed state.

[0054] The electronic device 1 provided in this embodiment includes but is not limited to mobile terminals such as mobile phones, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., and fixed terminals such as digital TVs and desktop computers. This embodiment does not limit the types of electronic devices 1, and only uses mobile phones for schematic illustration.

[0055] The electronic device 1 mainly includes a folding device 2, a housing assembly 3, a flexible screen 90, and an elastic member 4, which means that the electronic device 1 of this embodiment only needs to use the folding device 2, the housing assembly 3, the flexible screen 90, and the elastic member 4 to solve the above-mentioned technical problems. However, this does not mean that the electronic device 1 can only include these components. The electronic device 1 can also include other components such as circuit boards, batteries, cameras, etc. Next, this embodiment will introduce the folding device 2, the housing assembly 3, the flexible screen 90, and the elastic member 4 in detail.

[0056] The folding device 2 is mainly used to realize the folding function of the electronic device 1, thereby driving the housing assembly 3 to move, and then driving the flexible screen 90 to unfold or fold. The specific structure and working principle of the folding device 2 will be described in detail later in this application.

[0057] The housing assembly 3 is mainly used to install and carry various components. For example, the folding device 2 can be installed on the housing assembly 3, so that the movement trajectory of the housing assembly 3 can be controlled by the folding device 2. In other words, the housing assembly 3 can also control the movement of the folding device 2 in turn. Functional modules such as batteries, PCB components, speakers, receivers, buttons, etc. can also be set in the housing assembly 3. And a flexible screen 90 can also be set on the housing assembly 3, so that the movement trajectory of the flexible screen 90 can be controlled by the housing assembly 3. In other words, the flexible screen 90 can also control the movement of the housing assembly 3 in turn. In some embodiments, the surface of the housing assembly 3 can also serve as an appearance surface, so the surface of the housing assembly 3 can be designed accordingly to give the housing assembly 3 a unique appearance effect. This embodiment does not limit the parameters such as the shape, material, and structure of the housing assembly 3, as long as the installation and protection functions can be achieved. For example, the material of the housing assembly 3 can be all metal, or all plastic, or partly metal and partly plastic.

[0058] The two housing components 3 are located on opposite sides of the folding device 2, for example, one housing component 3 is located on one side of the folding device 2, and the other housing component 3 is located on the other side of the folding device 2. In this embodiment, each housing component 3 is connected to the folding device 2, providing a basis for the subsequent cooperation with the elastic member 4 to pull the flexible screen 90. As for which part of the folding device 2 the housing component 3 is connected to and the specific structure of the connection, this application will be described in detail later.

[0059] The flexible screen 90 is a component with a certain degree of flexibility. Compared with a rigid component, the flexible screen 90 can be bent to a certain extent. For example, the flexible screen 90 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 90 is arranged on the same side of the two shell components 3 and the folding device 2, and the opposite ends of the flexible screen 90 are respectively fixed to the two shell components 3. For example, one end of the flexible screen 90 can be attached to one shell component 3 by an adhesive such as a double-sided adhesive, and the other end of the flexible screen 90 can also be attached to another shell component 3 by an adhesive such as a double-sided adhesive, and the flexible screen 90 can be folded or flattened with the shell component 3. Specifically, the flexible screen 90 has a bending area 91 and non-bending areas 92 arranged on opposite sides of the bending area 91. The bending area 91 is arranged corresponding to the folding device 2, and the non-bending area 92 is correspondingly attached to the two shell components 3. During the movement of the electronic device 1, only the flexible screen 90 in the bending area 91 will bend under the drive of the folding device 2, and fold and unfold with the movement of the electronic device 1. Since the flexible screen 90 in the non-bending area 92 is attached to the two shell components 3, the two shell components 3 will only rotate and / or move relative to each other, and the shape itself will not change. Therefore, even if the two shell components 3 move, the flexible screen 90 in the non-bending area 92 will not bend. Therefore, usually only the flexible screen 90 in the bending area 91 will have creases after multiple bending.

[0060] The electronic device 1 has two different states during the folding and unfolding process: an unfolded state and a folded state. Figure 1-Figure 4 As shown, the unfolded state refers to the state when the two housing components 3 are fully unfolded to each other, which can also be understood as the state when the flexible screen 90 is flattened, or the state when the display surface of the flexible screen 90 is flush. In other words, the unfolded state is the limit state of the electronic device 1 during the unfolding process. Figure 5-Figure 7 As shown, the folded state refers to the state when the two shell components 3 are completely folded with each other, which can also be understood as the state when the flexible screen 90 is bent and the two halves of the flexible screen 90 are close to each other, or the state when the display surface of the flexible screen 90 is bent. In other words, the folded state is the limit state of the electronic device 1 during the folding process. When the electronic device 1 is folded, the two shell components 3 are folded with each other, and the two ends of the flexible screen 90 are folded with each other. When the electronic device 1 is unfolded, the two shell components 3 are unfolded with each other, and the two ends of the flexible screen 90 are unfolded with each other.

[0061] like Figure 8As shown, the flexible screen 90 will produce creases at the bending area 91 after static bending or multiple bending. In this embodiment, two elastic members 4 are added to reduce or even eliminate the creases. The elastic member 4, as the name implies, is an elastic member. Optionally, the elastic member 4 includes but is not limited to a spring, a coil spring, a volute spring, a leaf spring, a disc spring, a torsion spring, and the like. The opposite ends of each elastic member 4 are respectively abutted against the folding device 2 and a shell component 3. Specifically, one end of an elastic member 4 abuts against one side of the folding device 2, and the other end abuts against a shell component 3. One end of another elastic member 4 abuts against the other side of the folding device 2, and the other end abuts against another shell component 3. And no matter when the electronic device 1 is in the unfolded state or the folded state, the elastic member 4 is in a compressed state, that is, when the electronic device 1 moves, the elastic member 4 is always in a compressed state. The elastic member 4 in the compressed state can use its elastic force to push the shell component 3 to move outward relative to the folding device 2. In addition, since the two ends of the flexible screen 90 are fixed on the shell component 3, as shown in FIG. Figure 3 and Figure 6 As shown, under the action of the elastic member 4, the two housing components 3 pull the two ends of the flexible screen 90 outward respectively. At this time, the elastic member 4 can also be called a straightening spring. In other words, this embodiment uses the spring force to pull the two ends of the flexible screen 90, which is equivalent to pulling the two ends of the crease position. The flexible screen 90 is straightened under the action of the pulling force at both ends, and the crease can achieve the effect of reducing the crease under the action of the pulling force at both ends, thereby improving the display performance and service life of the flexible screen 90.

[0062] Optionally, the electronic device 1 may further include a decorative piece 5 for fixing the base of the folding device 2 to effectively shield and protect various components of the folding device 2 .

[0063] Please refer again Figure 4 and Figure 7 In this embodiment, the folding device 2 includes a base 10 and two connecting members 50 disposed on opposite sides of the base 10. The two connecting members 50 can rotate relative to the base 10. Two housing components 3 are disposed on opposite sides of the base 10 and are respectively connected to one connecting member 50. One end of the elastic member 4 close to the base 10 abuts against the connecting member 50, and the other end of the elastic member 4 away from the base 10 abuts against the housing component 3.

[0064] The folding device 2 includes a base 10 and two connecting members 50 located on opposite sides of the base 10. When the electronic device 1 moves, the base 10 remains fixed and the two connecting members 50 can rotate relative to the base 10. Specifically, the connecting member 50 can be rotated relative to the base 10 by cooperating with other components of the folding device 2, such as the first rotating member, the second rotating member and other components. The housing assembly 3 located on the same side of the base 10 is connected to a connecting member 50, for example, one housing assembly 3 on one side of the base 10 is connected to a connecting member 50, and another housing assembly 3 on the other side of the base 10 is connected to another connecting member 50. The two elastic members 4 are respectively matched with the housing assembly 3 and the connecting member 50 on opposite sides of the base 10, for example, one end of an elastic member 4 abuts against one connecting member 50, and the other end abuts against one housing assembly 3, and one end of another elastic member 4 abuts against another connecting member 50, and the other end abuts against another housing assembly 3. In other words, the housing assembly 3, the connecting member 50, and the elastic member 4 on both sides of the base 10 are arranged axially symmetrically with respect to the base 10.

[0065] One end of the elastic member 4 is closer to the base 10 than the other end, that is, the end of the elastic member 4 close to the base 10 abuts against the connecting member 50, and the other end of the elastic member 4 away from the base 10 abuts against the shell assembly 3. Since the connecting member 50 is restricted by the constraints of other components in the folding device 2 and remains fixed, the elastic force direction of the elastic member 4 in the compressed state is in the direction away from the base 10, that is, the elastic member 4 will give the shell assembly 3 an outward elastic force, so that the shell assembly 3 has the ability to move outward, thereby pulling the two ends of the flexible screen 90 outward.

[0066] In addition, when the electronic device 1 is folded, the two opposite ends of the flexible screen 90 are close to each other, the housing assembly 3 and the connecting member 50 rotate relative to the base 10, and the housing assembly 3 slides relative to the connecting member 50 in a direction away from the base 10. When the electronic device 1 is unfolded, the two opposite ends of the flexible screen 90 are unfolded, the housing assembly 3 and the connecting member 50 rotate relative to the base 10, and the housing assembly 3 slides relative to the connecting member 50 in a direction close to the base 10.

[0067] When the electronic device 1 is folded, that is, when the electronic device 1 is in the process of changing from the unfolded state to the folded state, that is, from Figures 4 to 7During the folding process, the two shell components 3 will drive the connecting member 50 to rotate relative to the base 10 and approach each other, thereby driving the two ends of the flexible screen 90 to approach each other. When the flexible screen 90 is folded, the flexible screen 90 will drive the shell component 3 to slide relative to the connecting member 50 in a direction away from the base 10, so that the elastic member 4 in the compressed state gradually stretches, reducing the elastic force of the elastic member 4. However, when the electronic device 1 is in the folded state, the elastic member 4 is still in a compressed state. Therefore, during the entire folding process of the electronic device 1, the elastic member 4 is always in a compressed state, so that the opposite ends of the flexible screen 90 are always under outward pulling force, effectively reducing the crease of the flexible screen 90.

[0068] Similarly, when the electronic device 1 is unfolded, that is, when the electronic device 1 is in the process of changing from the folded state to the unfolded state, that is, from Figure 7 to Figure 4 During the process, the two shell components 3 will drive the connecting member 50 to rotate in the opposite direction relative to the base 10 and move away from each other, thereby driving the two ends of the flexible screen 90 to unfold. When the flexible screen 90 is unfolding, the flexible screen 90 will drive the shell component 3 to slide relative to the connecting member 50 in the direction close to the base 10, thereby gradually shortening the elastic member 4 that is already in a compressed state, further increasing the elastic force of the elastic member 4. Therefore, when the electronic device 1 is in the unfolded state, the elastic force of the elastic member 4 is the largest. In other words, the tension on the two opposite ends of the flexible screen 90 is also the largest, further reducing the crease of the flexible screen 90.

[0069] Optionally, during the movement of the electronic device 1, the pushing stroke of the elastic member 4 is 0.15mm-0.3mm. In other words, the sliding distance of the shell component 3 relative to the connecting member 50 is 0.15mm-0.3mm, which can prevent the pushing stroke from being too small, so that the elastic member 4 is not in a compressed state when in the folded state, and can also prevent the pushing stroke from being too large, so that the shell component 3 slides too far relative to the connecting member 50, thereby exposing the folding device 2 and affecting the appearance and reliability of the electronic device 1. In addition, since the pushing stroke of the elastic member 4 is 0.15mm-0.3mm, the distance that the shell component 3 can be pushed in the folded state is small, and the reliability of the whole machine falling is improved under the buffering effect of the elastic member 4. Further optionally, the pushing stroke of the elastic member 4 can be 0.18mm, 0.2mm, 0.22mm, 0.24mm, 0.26mm, 0.28mm, 0.3mm, etc.

[0070] Please refer to Figure 4 , Figure 7 ,and Fig.10In this embodiment, the shell assembly 3 includes a shell 20 and a sliding member 21 fixed to the shell 20. The sliding member 21 is arranged on the side of the connecting member 50 away from the flexible screen 90 and is slidably connected to the connecting member 50. A first supporting portion 211 is provided on the side of the sliding member 21 close to the connecting member 50, and a second supporting portion 501 is provided on the side of the connecting member 50 close to the sliding member 21. The first supporting portion 211 is farther away from the base 10 than the second supporting portion 501, and the opposite ends of the elastic member 4 respectively abut the first supporting portion 211 and the second supporting portion 501.

[0071] The shell assembly 3 is a modular component, that is, the shell assembly 3 is composed of multiple components. The shell assembly 3 of this embodiment includes a shell 20 and a sliding member 21, and the flexible screen 90 and the sliding member 21 are both fixed to the shell 20. Optionally, the sliding member 21 and the shell 20 can be an integrated structure or a split structure. When the sliding member 21 and the shell 20 are a split structure, the sliding member 21 can be fixed to the shell 20 by screw connection, snap connection, bonding, etc. This embodiment is only schematically illustrated by fixing the sliding member 21 to the shell 20 by screws 201.

[0072] The sliding member 21 is arranged on the side of the connecting member 50 away from the flexible screen 90, that is, the sliding member 21 is located below the connecting member 50 and is slidably connected to the connecting member 50. Specifically, a first abutting portion 211 is convexly provided on the side of the sliding member 21 close to the connecting member 50, that is, on the upper surface of the sliding member 21, and correspondingly, a second abutting portion 501 is convexly provided on the side of the connecting member 50 close to the sliding member 21, that is, on the lower surface of the connecting member 50. One end of the elastic member 4 abuts against the first abutting portion 211, and the other end abuts against the second abutting portion 501, and the first abutting portion 211 is farther away from the base 10 than the second abutting portion 501, so that the end of the elastic member 4 abutting against the connecting member 50 is closer to the base 10 than the end of the elastic member 4 abutting against the shell assembly 3, thereby making the elastic force on the sliding member 21 and the shell 20 outward, and the sliding member 21 can also be called a straightened sliding member 21. The first abutting portion 211 cooperates with the second abutting portion 501 and the elastic member 4 to simplify the structures of the sliding member 21 and the connecting member 50 and reduce the difficulty of assembling the elastic member 4 .

[0073] Optionally, the arrangement direction of the first abutting portion 211 and the second abutting portion 501 is parallel to the axial direction of the elastic member 4, so that the elastic force of the elastic member 4 can be better transmitted to the sliding member 21 of the shell 20, and then transmitted to the shell 20 fixed to the sliding member 21 through the sliding member 21, and finally transmitted to the flexible screen 90.

[0074] Please refer again Fig.10In this embodiment, the sliding member 21 and the housing 20 are connected by the positioning shaft 212 and the positioning hole 202. The positioning shaft 212 is provided at one of the sliding member 21 and the housing 20, and the positioning hole 202 is provided at the other of the sliding member 21 and the housing 20. When the positioning shaft 212 is provided at the sliding member 21, the positioning hole 202 is provided at the housing 20. When the positioning hole 202 is provided at the sliding member 21, the positioning shaft 212 is provided at the housing 20. In this embodiment, the positioning shaft 212 is provided at the sliding member 21 and the positioning hole 202 is provided at the housing 20 for schematic description. Of course, in other embodiments, the positioning shaft 212 can also be provided at the housing 20, and the positioning hole 202 can be provided at the sliding member 21. The cooperation between the positioning shaft 212 and the positioning hole 202 can reduce the difficulty of positioning when the sliding member 21 and the housing 20 are installed, and improve the positioning accuracy. Specifically, two positioning shafts 212 are provided on the sliding member 21 , and two positioning holes 202 are provided on the housing 20 . The two positioning shafts 212 cooperate with the two positioning holes 202 to limit the position of the sliding member 21 on the housing 20 .

[0075] Please refer again Figure 4 ,and Figure 11-Figure 12 In this embodiment, a first receiving groove 502 is provided on the side of the connecting member 50 facing away from the flexible screen 90, the sliding member 21 and the elastic member 4 are arranged in the first receiving groove 502, and the groove wall of the first receiving groove 502 and the sliding member 21 are connected with the sliding groove 503 through the slider 213, the slider 213 is provided at one of the groove wall of the first receiving groove 502 and the sliding member 21, and the sliding groove 503 is provided at the other of the groove wall of the first receiving groove 502 and the sliding member 21.

[0076] By providing a first receiving groove 502 on the side of the connecting member 50 away from the flexible screen 90, i.e., on the lower surface of the connecting member 50, and arranging the sliding member 21 and the elastic member 4 in the first receiving groove 502, the overall thickness of the connecting member 50, the sliding member 21, and the elastic member 4 can be reduced, thereby reducing the thickness of the entire device. In addition, the groove wall of the first receiving groove 502 and the sliding member 21 can be connected with the sliding groove 503 through the slider 213, thereby realizing the sliding connection of the sliding member 21 to the connecting member 50 mentioned above. For example, when the slider 213 is arranged on the groove wall of the first receiving groove 502, the sliding groove 503 is arranged on the sliding member 21, and when the sliding groove 503 is arranged on the groove wall of the first receiving groove 502, the slider 213 is arranged on the sliding member 21. This embodiment is only schematically described with the sliding groove 503 being arranged on the groove wall of the first receiving groove 502 and the slider 213 being arranged on the sliding member 21. Specifically, groove walls on opposite sides of the first receiving groove 502 are recessed with sliding grooves 503 , and sliders 213 are convexly disposed on opposite sides of the sliding member 21 . The sliders 213 are disposed in the sliding grooves 503 to achieve sliding connection of the sliding member 21 to the connecting member 50 .

[0077] In this embodiment, a second receiving groove 214 is provided on the side of the sliding member 21 close to the connecting member 50, and the elastic member 4 is provided in the second receiving groove 214. By opening the second receiving groove 214 on the side of the sliding member 21 close to the connecting member 50, that is, above the sliding member 21, and then arranging the elastic member 4 in the second receiving groove 214, the overall thickness of the connecting member 50, the sliding member 21, and the elastic member 4 can be further reduced, thereby reducing the thickness of the entire device. The groove wall of the second receiving groove 214 can also limit the elastic member 4 to prevent the elastic member 4 from separating from the sliding member 21, thereby improving the stability of the elastic member 4.

[0078] Please refer to Figure 13-Figure 19 In this embodiment, when the electronic device 1 changes from the unfolded state to the critical state, the housing component 3 slides relative to the connecting member 50 in a direction away from the base 10, and when the electronic device 1 changes from the critical state to the folded state, the housing component 3 is fixed relative to the connecting member 50. When the electronic device 1 changes from the folded state to the critical state, the housing component 3 is fixed relative to the connecting member 50, and when the electronic device 1 changes from the critical state to the unfolded state, the housing component 3 slides relative to the connecting member 50 in a direction close to the base 10.

[0079] This embodiment allows the housing component 3 to not slide relative to the connecting member 50 in a direction away from the base 10 all the time when the electronic device 1 is folded, i.e., during the process from the unfolded state to the folded state, but at a certain moment the housing component 3 no longer slides relative to the connecting member 50, and the housing component 3 and the connecting member 50 remain fixed. Therefore, this moment can be called the critical state of the electronic device 1. In other words, the critical state is the moment when the motion relationship between the housing component 3 and the connecting member 50 changes. When the electronic device 1 changes from the unfolded state to the critical state, the housing component 3 slides relative to the connecting member 50 in a direction away from the base 10, and the pushing stroke of the elastic member 4 gradually increases. When the electronic device 1 changes from the critical state to the folded state, the pushing stroke of the elastic member 4 has been completed, so the housing component 3 is always fixed relative to the connecting member 50, thereby preventing the housing component 3 from sliding relative to the connecting member 50 all the time and exposing the folding device 2. Similarly, when the electronic device 1 changes from the folded state to the critical state, the shell assembly 3 is fixed relative to the connecting member 50, and when the electronic device 1 changes from the critical state to the unfolded state, the elastic member 4 begins to be gradually compressed, and the shell assembly 3 slides relative to the connecting member 50 in a direction close to the base 10.

[0080] Optionally, when the electronic device 1 is in the process of changing from the unfolded state to the folded state, the housing assembly 3 will rotate 90° relative to the base 10, and when the electronic device 1 is in the critical state, the housing assembly 3 will rotate 5°-30° relative to the base 10. The specific rotation degree of the housing assembly 3 relative to the base 10 in the critical state is related to the specific structure of the folding device 2, the size of the pushing stroke of the elastic member 4 and other factors, and can be adjusted according to actual conditions.

[0081] Please refer to Figure 13-Figure 21 In this embodiment, the sliding member 21 and the connecting member 50 are connected by the limiting shaft 215 and the limiting groove 504. The limiting shaft 215 is provided at one of the sliding member 21 and the connecting member 50, and the limiting groove 504 is provided at the other of the sliding member 21 and the connecting member 50. The limiting groove 504 includes a first limiting end 5041 and a second limiting end 5042 that are arranged opposite to each other. When the electronic device 1 is in the unfolded state, the limiting shaft 215 is close to the first limiting end 5041, and when the electronic device 1 is folded, the limiting shaft 215 is located at the second limiting end 5042.

[0082] A limiting shaft 215 and a limiting groove 504 may also be provided between the sliding member 21 and the connecting member 50. For example, when the limiting shaft 215 is provided on the sliding member 21, the limiting groove 504 is provided on the connecting member 50. When the limiting groove 504 is provided on the sliding member 21, the limiting shaft 215 is provided on the connecting member 50. In this embodiment, the limiting shaft 215 is provided on the sliding member 21 and the limiting groove 504 is provided on the connecting member 50 for schematic illustration. Of course, in other embodiments, the limiting shaft 215 may also be provided on the connecting member 50, and the limiting groove 504 may be provided on the sliding member 21. Optionally, the limiting shaft 215 and the sliding member 21 may be an integrated structure or a split structure. When the limiting shaft 215 and the sliding member 21 are a split structure, the limiting shaft 215 and the sliding member 21 may be fixed to the sliding member 21 by screw connection, snap connection, bonding, etc. In this embodiment, the limiting shaft 215 is schematically illustrated as a screw 216 . The screw 216 passes through and is fixed on the sliding member 21 , and the portion of the screw 216 passing through the sliding member 21 is the limiting shaft 215 .

[0083] The limiting groove 504 includes two oppositely arranged ends: a first limiting end 5041 and a second limiting end 5042. When the limiting groove 504 is arranged on the connecting member 50, the first limiting end 5041 is closer to the base 10 than the second limiting end 5042. In other words, the first limiting end 5041 is arranged more inwardly than the second limiting end 5042. When the electronic device 1 is in the unfolded state, the limiting shaft 215 is close to the first limiting end 5041, where close can be understood as the limiting shaft 215 abutting and positioning at the first limiting end 5041, or the limiting shaft 215 and the first limiting end 5041 have a certain distance, so that the limiting shaft 215 has a variety of different position conditions in the unfolded state, and the first limiting end 5041 is used to limit the contraction distance of the sliding member 21 and the housing 20, in other words, to control the pushing stroke of the elastic member 4 when it contracts. When the electronic device 1 is folded, the limiting shaft 215 is positioned at the second limiting end 5042 , and the second limiting end 5042 is used to limit the extension distance of the sliding member 21 and the housing 20 , in other words, to control the pushing stroke of the elastic member 4 when it is extended.

[0084] When the electronic device 1 is folded, the movement of the flexible screen 90 enables the housing assembly 3 to slide outward, and the elastic member 4 in the compressed state pushes the sliding member 21 and the housing 20 outward, that is, the limiting shaft 215 slides from the first limiting end 5041 to the second limiting end 5042. When the electronic device 1 moves to a critical state, the limiting shaft 215 abuts against the second limiting end 5042. At this time, the elastic member 4 can no longer push the sliding member 21 and the housing 20 to slide outward. Under the action of the elastic member 4, the housing 20 pulls the two ends of the flexible screen 90, and the flexible screen 90 achieves the effect of reducing the crease under the action of the pulling force at both ends. When the electronic device 1 is unfolded, the housing 20 and the sliding member 21 remain fixed relative to the connecting member 50 at the beginning. When in a critical state, the unfolding of the flexible screen 90 will drive the housing 20 and the sliding member 21 to slide inward, that is, the limit shaft 215 slides from the second limit end 5042 to the first limit end 5041. At this time, the elastic member 4, which is already in a compressed state, is gradually compressed. Under the action of the elastic member 4, the housing 20 pulls the two ends of the flexible screen 90. The flexible screen 90 achieves the effect of reducing creases under the action of the tension at both ends. When the electronic device 1 is in the unfolded state, the limit shaft 215 is close to the first limit end 5041, so that the housing 20 and the sliding member 21 can no longer slide. The elastic member 4 has the largest elastic force, and the effect of reducing creases is the best.

[0085] In summary, the present embodiment utilizes the cooperation between the limiting shaft 215 and the limiting groove 504 to control the pushing stroke of the elastic member 4, thereby controlling the sliding distance of the housing assembly 3. For example, this can be achieved by controlling the size of the limiting groove 504 and the limiting shaft 215, the distance between the limiting shaft 215 and the first limiting end 5041 and the second limiting end 5042, and the like.

[0086] In this embodiment, when the electronic device 1 is in the unfolded state and the flexible screen 90 has a crease, the elastic member 4 can push the shell 20 to move in a direction away from the base 10 and cause the limiting shaft 215 to slide in the limiting groove 504, thereby subjecting the end of the flexible screen 90 to tension.

[0087] When the electronic device 1 is in the unfolded state and the flexible screen 90 already has a crease, in other words, the length of the flexible screen 90 is greater than the length of the flexible screen 90 when there is no crease. At this time, the elastic member 4 in the compressed state can push the housing 20 and the sliding member 21 to slide in the direction away from the base 10, and make the limiting shaft 215 slide in the limiting groove 504 from the first limiting end 5041 to the second limiting end 5042, so that the end of the flexible screen 90 is subjected to tension, and the crease of the flexible screen 90 is reduced or even eliminated, so that the flexible screen 90 is flattened again. The setting of the elastic member 4 and the limiting structure can not only apply an outward pulling force to the flexible screen 90 during the movement of the electronic device 1, thereby effectively preventing the flexible screen 90 from creases. It can also reduce or eliminate the creases of the flexible screen 90 when the flexible screen 90 has already creased.

[0088] It is worth noting that the above-mentioned pushing stroke of the elastic member 4 of 0.15mm-0.3mm not only needs to meet various requirements of the elastic member 4 at the beginning. When the flexible screen 90 has a crease, the elastic member 4 will stretch, which means that the pushing stroke of the elastic member 4 is reduced. The pushing stroke of 0.15mm-0.3mm can still meet the situation after the elastic member 4 is stretched, preventing the pushing stroke of the elastic member 4 from being too small after stretching.

[0089] Optionally, the limit shaft 215 can be positioned at the first limit end 5041 during installation, that is, the limit shaft 215 abuts against the first limit end 5041 when the electronic device 1 is in the unfolded state. However, as the flexible screen 90 continues to bend, when a crease appears on the flexible screen 90, the elastic member 4 pushes the limit shaft 215 to slide from the first limit end 5041 to the second limit end 5042 to flatten the flexible screen 90 again. At this time, the limit shaft 215 no longer abuts against the first limit end 5041 in the unfolded state, but has a certain distance from the first limit end 5041. Therefore, the above content also explains why the limit shaft 215 has multiple positions at the first limit end 5041.

[0090] Please refer to Figure 22-Figure 27In this embodiment, the folding device 2 includes a base 10, two first rotating members 30, two second rotating members 40, a connecting member 50, and two supporting members 60. The two first rotating members 30 are respectively rotatably connected to opposite sides of the base 10. The two second rotating members 40 are respectively rotatably connected to opposite sides of the base 10. The connecting member 50 is located on the same side of the base 10. One of the first rotating member 30 and the second rotating member 40 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 one second rotating member 40.

[0091] The base 10 is the basic component in the folding device 2, which mainly provides a foundation for the installation of other components, that is, many other components of the folding device 2 can be installed on the base 10. And the base 10 itself is fixed, and it is mainly other components installed on the base 10 that perform various movements. In addition, the base 10 can also play a role in supporting the supported parts 60 in some embodiments. The supported parts 60 include but are not limited to various flexible screens 90, or various rigid parts, or other components. 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 basis for other components.

[0092] Alternatively, if Fig. 27 As shown, the base 10 has a top surface 101, a first bottom surface 102, and a side surface that is bent and connected between the top surface 101 and the first bottom surface 102. When the folding device 2 is subsequently applied to the electronic device 1, the top surface 101 can be close to the flexible screen 90 of the electronic device 1, and the first bottom surface 102 is far away from the flexible screen 90 of the electronic device 1. The first bottom surface 102 is used to be installed on other components. For example, the first bottom surface 102 can be fixed on the decorative member 5 to achieve the installation of the base 10. The top surface 101 is used to carry the flexible screen 90, or to install other components used to carry the flexible screen 90, such as the support member 60. The side surface can be used to install other components.

[0093] The two first rotating members 30 in the folding device 2 mainly realize the folding function through their ability to rotate, and through the rotation of the two first rotating members 30, the components connected to 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 one end of the base 10, and the two first rotating members 30 are respectively arranged on opposite sides of the base 10. That is, the two first rotating members 30 can rotate relative to the base 10, which can facilitate the subsequent cooperation of the two first rotating members 30 with the linkage member. 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. As for the specific cooperation structure of the two first rotating members 30 and the base 10, it will be described in detail later. It is worth noting that 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 text can be understood in the same way. The present embodiment does not limit parameters such as the shape, structure, and material of the first rotating member 30 , as long as the first rotating member 30 can be rotatably connected to the base 10 .

[0094] 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 asymmetrically with respect to the base 10, in other words, the two first rotating members 30 have a partially overlapping area in the thickness direction of the folding device 2. This embodiment is only schematically described with the two first rotating members 30 being arranged axially symmetrically with respect to the base 10.

[0095] The second rotating member 40 has the same function as the first rotating member 30. In the folding device 2, 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 are rotatably connected to the other opposite end of the base 10, that is, the two second rotating members 40 and the two first rotating members 30 are arranged at the opposite ends of the base 10, which not only simplifies the structure of the folding device 2, 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. As for the specific matching structure of the two second rotating members 40 and the base 10, this application will be described in detail later. The opposite ends of the base 10 mentioned above can be understood as the opposite ends of the length direction of the base 10, and the length direction is the axial direction of the base 10, or the central axis direction of the base 10. 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.

[0096] Optionally, in one embodiment, the two second rotating members 40 are arranged axially symmetrically with respect to the base 10. 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 thickness direction of the folding device 2. This embodiment is only schematically described with the two second rotating members 40 being arranged axially symmetrically with respect to the base 10.

[0097] The connecting member 50 mainly serves to connect various components in the folding device 2. 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. In other words, 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. This embodiment is only schematically illustrated by the first rotating member 30 being rotatably connected to the connecting member 50 and the second rotating member 40 being slidably connected to the connecting member 50, that is, each first rotating member 30 is rotatably connected to a connecting member 50, that is, each first rotating member 30 is rotatably connected to a connecting member 50 on one side away from the base 10. 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, each second rotating member 40 is slidably connected to a connecting member 50 on one side away from the base 10. In other words, the second rotating member 40 can slide relative to the connecting member 50. In addition, the connecting member 50 is subsequently used to connect the housing 20, so that the connecting member 50 and the housing 20 become a whole. In this way, when the housing 20 rotates, the connecting member 50 can also 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 and sliding connection with another rotating member.

[0098] In addition, when the folding device 2 is in the unfolded state, the two connecting members 50 are disposed on opposite sides of the base 10, that is, one connecting member 50 is disposed on one side of the base 10, and the other connecting member 50 is disposed on the other side of the base 10. When the folding device 2 is in the folded state, the two connecting members 50 are disposed on the same side of the base 10, that is, the two connecting members 50 are both disposed on the top surface 101 of the base 10.

[0099] The support member 60 is mainly used to support the flexible screen 90 when the folding device 2 is subsequently applied to the electronic device 1. 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 is slidably and rotatably connected to a second rotating member 40, that is, the support member 60 can rotate relative to the second rotating member 40, and the support member 60 can also slide relative to the second rotating member 40.

[0100] It should be noted here that the rotation mentioned above can be understood as the two parts being able to perform circular motion around the axis of rotation, with only angle changes but no displacement changes. Sliding can be understood as the two parts being able to perform parallel motion, with only displacement changes but no angle changes. The fact that the two parts can both slide and rotate means that the two parts have both displacement changes and angle changes, and this sliding and rotating can also be called rolling.

[0101] The folding device 2 provided in this embodiment can form a track mechanism 2a 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 2 includes a track mechanism 2a, which is arranged on one side of the support member 60. In another embodiment, the folding device 2 includes two track mechanisms 2a, which are arranged on one side of the support member 60, and the two track mechanisms 2a are arranged along the extension direction of the support member 60. At this time, the support member 60 is rotatably connected to the two connecting members 50, and is slidably and rotatably connected to the two second rotating members 40. In other embodiments, the folding device 2 includes three or more track mechanisms 2a, which are arranged on one side of the support member 60, and are arranged along the extension direction of the support member 60. At this time, the support member 60 is rotatably connected to three or more connecting members 50, and is slidably and rotatably connected to three or more second rotating members 40. This embodiment is only schematically described as the folding device 2 including two track mechanisms 2a and two support members 60.

[0102] Based on the above connection relationship, it can be known that the folding device 2 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 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*2 (a total of 1 high pair on one side, such as 1 rolling pair) = 1.

[0103] When the folding device 2 moves, the movement trajectory and movement route of each component are unique. Specifically, when 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 other of the first rotating member 30 and the second rotating member 40 slides relative to the connecting member 50, the supporting member 60 rotates relative to the connecting member 50, and slides and rotates relative to the second rotating member 40, and the first rotating member 30 and the second rotating member 40 of the torsion mechanism rotate relative to each other. The movement process of the folding device 2 mentioned above has a variety of active and passive logical relationships, and this application uses one of the specific movement processes as an example. When the folding device 2 is folded, that is, when the folding device 2 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. 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 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. Finally, the two support members 60 can be folded with each other.

[0104] Similarly, when the folding device 2 is unfolded, that is, when the folding device 2 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. Finally, the two supporting members 60 can be unfolded with each other. 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. Finally, the two supporting members 60 can be unfolded with each other. Of course, in other embodiments, the active and passive relationships of the above-mentioned multiple components can be reversed. For example, the support member 60 can also 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 belong to the protection scope of this application.

[0105] like Fig.25 As shown, when the two support members 60 are parallel to each other and the two support members 60 are located on opposite sides of the base 10, it can also be understood that one support member 60 is located on one side of the base 10 and the other support member 60 is located on the other side of the base 10. At this time, the two support members 60 are in a state of being fully unfolded with each other. In other words, the folding device 2 is in the above-mentioned unfolded state. Fig. 27 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 101 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 2 is in a folded state. When the two support members 60 are folded with each other, that is, the process of the folding device 2 from the unfolded state to the folded state can also be understood as the process from Figure 25 to Figure 27 When the two support members 60 are unfolded from each other, that is, the process of the folding device 2 from the folded state to the unfolded state can also be understood as the process from Figure 27 to Figure 25 process.

[0106] When the folding device 2 is in a folded state, the two support members 60 and the base 10 are jointly enclosed to form a receiving space 1a for receiving the flexible screen 90. The folding device 2 provided in this embodiment can make the cross-sectional shape of the receiving space 1a U-shaped or teardrop-shaped. When the cross-sectional shape of the receiving 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. When the cross-sectional shape of the receiving 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. This embodiment is only schematically illustrated with the cross-sectional shape of the receiving space 1a being teardrop-shaped. In summary, the folding device 2 provided in this embodiment can realize the mutual folding and mutual unfolding of the two support members 60 through the mutual cooperation of the above-mentioned components, that is, realize the folding and unfolding functions of the folding device 2.

[0107] Optionally, in addition to the support member 60, the folding device 2 may further include other support members 70 for supporting the flexible screen 90, for example, the support member 70 is disposed between two support members 60, the support member 70 is mounted on the base 10, and when the folding device 2 is in the unfolded state, the two support members 60 are arranged flush with the support member 70, so that three components are used to support the flexible screen 90. At this time, the support member 60 can also be called an inclined plate, and the support member 70 can also be called a middle plate. Optionally, the folding device 2 can be arranged axially symmetrically or asymmetrically relative to the base 10.

[0108] It is also worth noting that the present application will introduce the specific components of the folding device 2 in detail below. Since most of the components are two in number and are symmetrically arranged relative to the base 10, this embodiment only describes the following. Fig.24 The components on the right side of the base 10 in the folding device 2 are schematically illustrated, and the same understanding can be applied to the components on the left side of the base 10 .

[0109] Please refer to Fig.28In this embodiment, the first rotating member 30 and the second rotating member 40 are respectively located at opposite ends of the base 10. The rotation axis between the first rotating member 30 and the base 10 and the rotation axis between the second rotating member 40 and the base 10 do not coincide. In other words, the rotation axis between the first rotating member 30 and the base 10 (as shown in C1) and the rotation axis between the second rotating member 40 and the base 10 (as shown in C2) are parallel to each other and have a spacing. In this way, no matter whether the folding device 2 is folded or unfolded, when the connecting member 50 rotates relative to the base 10, thereby driving the first rotating member 30 and the second rotating member 40 to rotate relative to the base 10, since the rotation axis C1 between the first rotating member 30 and the base 10 and the rotation axis C2 between the second rotating member 40 and the base 10 do not coincide, the connecting member 50 can slide 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 realizing the subsequent movement process.

[0110] In summary, this embodiment does not require the addition of new components. It only requires the design of the positions of the rotation axis C1 between the first rotating member 30 and the base 10 and the rotation axis C2 between the second rotating member 40 and the base 10 to achieve the sliding of the connecting member 50 relative to the second rotating member 40 .

[0111] In this embodiment, the base 10 has a first bottom surface 102 . When the folding device 2 is in the unfolded state, the rotation axis C1 between the first rotating member 30 and the base 10 is farther from the first bottom surface 102 and the connecting member 50 than the rotation axis C2 between the second rotating member 40 and the base 10 .

[0112] The base 10 has a top surface 101 and a first bottom surface 102 that are arranged opposite to each other. The above contents about the top surface 101 and the first bottom surface 102 have been described in detail, and will not be repeated here in this embodiment. On the basis that the rotation axis C1 between the first rotating member 30 and the base 10 and the rotation axis C2 between the second rotating member 40 and the base 10 do not coincide, this embodiment can also make the rotation axis C1 between the first rotating member 30 and the base 10 farther away from the first bottom surface 102 than the rotation axis C2 between the second rotating member 40 and the base 10, and at the same time make the rotation axis C1 between the first rotating member 30 and the base 10 farther away from the connecting member 50 than the rotation axis C2 between the second rotating member 40 and the base 10. In other words, the rotation axis C1 between the first rotating member 30 and the base 10 is higher and further to the left than the rotation axis C2 between the second rotating member 40 and the base 10. Therefore, Fig.28 In the figure, the rotation axis C1 between the first rotating member 30 and the base 10 is located at the upper left, and the rotation axis C2 between the second rotating member 40 and the base 10 is located at the lower right.

[0113] By designing the position of the rotation axis as described above, 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 2 is in the unfolded state to the folded state on the basis of sliding the connecting member 50 relative to the second rotating member 40. When the folding device 2 is in the unfolded state to the unfolded state, the connecting member 50 slides in a direction close to the base 10, which can further make the supporting member 60 move according to a preset trajectory, so that when the folding device 2 is in the folded state, the folding device 2 forms a water drop-shaped receiving space 1a.

[0114] Please refer to Fig.29 In this embodiment, the first rotating member 30 and the base 10 are connected by the first arc rail 32 and the first arc groove 14. The first arc rail 32 is provided on one of the first rotating member 30 and the base 10, and the first arc groove 14 is provided on the other of the first rotating member 30 and the base 10. For example, when the first arc rail 32 is provided on the first rotating member 30, the first arc groove 14 is provided on the base 10. When the first arc groove 14 is provided on the first rotating member 30, the first arc rail 32 is provided on the base 10. In this embodiment, the first arc rail 32 is provided on the first rotating member 30 and the first arc groove 14 is provided on the base 10 for schematic description.

[0115] 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 circular arc rail 32. A protrusion is provided on the base 10, and a circular arc groove is provided in the protrusion, and the groove is the first circular arc groove 14. The first circular arc rail 32 can be provided in the first circular arc groove 14, and the axis of the first circular arc groove 14 is colinear with the axis of the first circular arc rail 32, 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 503.

[0116] As for the size and curvature of the first arc groove 14 and the first arc track 32, they can be designed according to the position of the rotation axis C1 between the first rotating member 30 and the base 10. The design of the first arc groove 14 and the first arc track 32 can make the position of the rotation axis C1 inside the base 10 or outside the base 10. By adjusting the size and curvature of the first arc groove 14 and the first arc track 32, the position of the rotation axis can be better designed, thereby achieving the positional relationship between the rotation axis C1 and the rotation axis C2. Of course, in other embodiments, the first arc groove 14 can also be provided on the first rotating member 30, and the first arc track 32 can be provided on the base 10.

[0117] In summary, the present embodiment can better adjust the position of the rotation axis C1 by adopting the rotation connection scheme of the first arc groove 14 and the first arc rail 32, so as to achieve the purpose of making the rotation axis C1 and the rotation axis C2 parallel to each other. In addition, the matching form of the first arc groove 14 and the first arc rail 32 can change the distance between the end of the first rotating member 30 away from the base 10 and the base 10 when the first rotating member 30 rotates relative to the base 10, thereby adjusting the distance between the first rotating member 30 and the base 10, and further achieving the purpose of controlling the first support member 60 to slide relative to the base 10.

[0118] Please refer to Fig.30 In this embodiment, the second rotating member 40 and the base 10 are connected by the first rotating shaft 41 and the first rotating hole 103. The first rotating shaft 41 is provided at one of the second rotating member 40 and the base 10, and the first rotating hole 103 is provided at the other of the second rotating member 40 and the base 10.

[0119] 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 through the first rotating shaft 41 and the first rotating hole 103 in this embodiment. The first rotating shaft 41 is provided on one of the second rotating member 40 and the base 10, and the first rotating hole 103 is provided on the other of the second rotating member 40 and the base 10. For example, when the first rotating shaft 41 is provided on the second rotating member 40, the first rotating hole 103 is provided on the base 10. When the first rotating hole 103 is provided on the second rotating member 40, the first rotating shaft 41 is provided on the base 10. This embodiment is only schematically described by providing the first rotating shaft 41 on the second rotating member 40 and the first rotating hole 103 on the base 10. Optionally, the first rotating shaft 41 includes but is not limited to a pin.

[0120] 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 14 and the first arc track 32, 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 14 and the first arc track 32. 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 41 and the first rotating hole 103 can be used to match, thereby simplifying the structure of the folding device 2.

[0121] Please refer to Fig.31 In this embodiment, the first rotating member 30 and the connecting member 50 are connected by the second rotating shaft 540 and the second rotating hole 310. The second rotating shaft 540 is provided at one of the first rotating member 30 and the connecting member 50, and the second rotating hole 310 is provided at the other of the first rotating member 30 and the connecting member 50.

[0122] 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 to each other through the second rotating shaft 540 and the second rotating hole 310 in this embodiment. The second rotating shaft 540 is provided on one of the first rotating member 30 and the connecting member 50, and the second rotating hole 310 is provided on the other of the first rotating member 30 and the connecting member 50. For example, when the second rotating shaft 540 is provided on the first rotating member 30, the second rotating hole 310 is provided on the connecting member 50. When the second rotating hole 310 is provided on the first rotating member 30, the second rotating shaft 540 is provided on the connecting member 50. This embodiment is only schematically described by providing the second rotating shaft 540 on the first rotating member 30 and the second rotating hole 310 on the connecting member 50. Optionally, the second rotating shaft 540 includes but is not limited to a pin.

[0123] 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 2.

[0124] Please refer to Fig.24 and Fig.32 In this embodiment, the second rotating member 40 and the connecting member 50 are connected by the sliding block 42 and the 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. Since the second rotating member 40 is slidably connected to the connecting member 50, in this embodiment, the second rotating member 40 and the connecting member 50 can be connected by the sliding block 42 and the 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. For example, when the sliding block 42 is provided at the second rotating member 40, the sliding groove 52 is provided at the connecting member 50. When the sliding groove 52 is provided at the second rotating member 40, the sliding block 42 is provided at the connecting member 50. In this embodiment, the sliding block 42 is provided at the second rotating member 40 and the sliding groove 52 is provided at the connecting member 50 for schematic description only.

[0125] Specifically, Fig.24As shown, the second rotating member 40 may be provided with protrusions on opposite sides thereof, and the protrusions are sliding blocks 42. The connecting member 50 may be provided with grooves, and sliding grooves are provided on the side walls on opposite sides of the grooves, and the sliding grooves are sliding grooves 52. The sliding block 42 may be arranged in the sliding groove 52 and slide along the extending direction of the sliding groove 52. The cooperation between the sliding block 42 and the sliding groove 52 may enable the second rotating member 40 to be better slidably connected to the connecting member 50.

[0126] Please refer again Fig.32 In this embodiment, the connecting member 50 has a second bottom surface 500 for facing away from the flexible screen 90, and the distance between the end of the sliding block 42 close to the base 10 and the second bottom surface 500 is smaller than the distance between the end of the sliding block 42 away from the base 10 and the second bottom surface 500.

[0127] When the folding device 2 is applied to the electronic device 1, the connecting member 50 has a second bottom surface 500 facing away from the flexible screen 90. In this embodiment, the distance between the end of the sliding block 42 close to the base 10 and the second bottom surface 500 can be smaller than the distance between the end of the sliding block 42 away from the base 10 and the second bottom surface 500. In other words, the sliding block 42 in this embodiment is not horizontally arranged but tilted, and the farther the sliding block 42 is from the base 10, the greater the distance between the sliding block 42 and the second bottom surface 500, that is, gradually tilted upward from left to right. In addition, since the sliding block 42 is tilted, the sliding matching the sliding block 42 is also tilted, and the distance between the end of the sliding groove 52 close to the base 10 and the second bottom surface 500 is smaller than the distance between the end of the sliding groove 52 away from the base 10 and the second bottom surface 500.

[0128] When the folding device 2 changes from the unfolded state to the folded state, the connecting member 50 slides relative to the second rotating member 40 in a direction away from the base 10. By designing the shapes of the sliding block 42 and the sliding groove 52, the supporting member 60 can be further moved according to a preset trajectory, so that the folding device 2 forms a water drop-shaped receiving space 1a when the folding device 2 is in the folded state. In addition, when the two connecting members 50 slide in a direction away from the base 10, the two connecting members 50 also approach each other, so that when the folding device 2 is in the folded state, the distance between the two connecting members 50 can be reduced, and the thickness of the folding device 2 in the folded state can be reduced. The opposite ends of the flexible screen 90 can also be abutted against each other, thereby eliminating the gap between the two ends of the flexible screen 90 in the folded state, improving the safety performance of the flexible screen 90, and improving the appearance effect.

[0129] Please refer to Fig.33In this embodiment, the support member 60 includes a support portion 61 and a rolling portion 62. The support portion 61 has a support surface 610 for supporting the flexible screen 90. The rolling portion 62 is arranged on the side of the support portion 61 away from the support surface 610. The second rotating member 40 and the rolling portion 62 are connected by a rolling shaft 43 and a rolling groove 620. The rolling shaft 43 is arranged on one of the second rotating member 40 and the rolling portion 62, and the rolling groove 620 is arranged on the other of the second rotating member 40 and the rolling portion 62.

[0130] The support member 60 includes a support portion 61 and a rolling portion 62, wherein the support portion 61 is used to support the flexible screen 90 when the folding device 2 is applied to the electronic device 1. Therefore, the support portion 61 has a support surface 610 that supports the flexible screen 90, that is, the upper surface of the support portion 61 is the support surface 610. The rolling portion 62 is arranged on the side of the support portion 61 away from the support surface 610, that is, the rolling portion 62 is farther away from the flexible screen 90 than the support portion 61. The rolling portion 62 is used to be connected to the second rotating member 40 in a sliding and rotatable manner. The support portion 61 and the rolling portion 62 can be an integral structure or a split structure. When the support portion 61 and the rolling portion 62 are an integral structure, the support portion 61 and the rolling portion 62 are prepared through one process, but for the sake of ease of understanding, the support portion 61 and the rolling portion 62 are artificially named differently. When the support portion 61 and the rolling portion 62 are separate structures, the support portion 61 and the rolling portion 62 are prepared separately and then connected together by various methods (such as bonding, snap connection, screw connection, etc.). This embodiment is only schematically described with the support portion 61 and the rolling portion 62 as an integrated structure.

[0131] In this embodiment, the second rotating member 40 and the rolling portion 62 can be connected by the rolling shaft 43 and the rolling groove 620. The rolling shaft 43 is provided on one of the second rotating member 40 and the rolling portion 62, and the rolling groove 620 is provided on the other of the second rotating member 40 and the rolling portion 62. For example, when the rolling shaft 43 is provided on the second rotating member 40, the rolling groove 620 is provided on the rolling portion 62. When the rolling groove 620 is provided on the second rotating member 40, the rolling shaft 43 is provided on the rolling portion 62. In this embodiment, the rolling shaft 43 is provided on the second rotating member 40 and the rolling groove 620 is provided on the rolling portion 62 for schematic description. The rolling shaft 43 can rotate relative to the rolling groove 620, so that the support member 60 rotates relative to the second rotating member 40. At the same time, the rolling shaft 43 can also slide relative to the rolling groove 620, so that the support member 60 slides relative to the second rotating member 40, so that the support member 60 slides and rotates relative to the second rotating member 40. Optionally, the rolling shaft 43 includes but is not limited to a pin.

[0132] Please refer to Figure 34-Figure 35In this embodiment, the rolling groove 620 has a first stop end 621 and a second stop end 622 that are arranged opposite to each other. The first stop end 621 is farther away from the base 10 than the second stop end 622, and the first stop end 621 is farther away from the support surface 610 than the second stop end 622. When the folding device 2 is in the unfolded state, the rolling shaft 43 is positioned at the first stop end 621, and when the folding device 2 is in the folded state, the rolling shaft 43 is positioned at the second stop end 622.

[0133] The rolling groove 620 has two opposite ends: a first stop end 621 and a second stop end 622. Since the rolling shaft 43 will slide in the rolling groove 620, the side walls of the first stop end 621 and the second stop end 622 can be used to indicate the sliding position of the rolling shaft 43, so that when the rolling shaft 43 slides to the first stop end 621 and the second stop end 622, the sliding stops and cannot continue to slide. Fig.34 As shown, the first stop end 621 is further away from the base 10 than the second stop end 622, and the first stop end 621 is further away from the support surface 610 than the second stop end 622. In other words, the first stop end 621 is further to the right and further down than the second stop end 622, that is, the first stop end 621 is located at the lower right position, and the second stop end 622 is located at the upper left position.

[0134] During the movement of the folding device 2, when the folding device 2 is in the unfolded state, the rolling shaft 43 is positioned at the first stop end 621 to prevent the support member 60 from folding back and damaging the subsequent flexible screen 90. When the folding device 2 is in the folded state, the rolling shaft 43 is positioned at the second stop end 622 to prevent the support member 60 from folding back and damaging the subsequent flexible screen 90. It can also be understood that when the folding device 2 is in the unfolded state, the rolling shaft 43 is located at the lower right, and when the folding device 2 is in the folded state, the rolling shaft 43 is located at the upper left.

[0135] Therefore, in the process of the folding device 2 changing from the unfolded state to the folded state, the connecting member 50 rotates relative to the base 10, driving the first rotating member 30 and the second rotating member 40 to rotate relative to the base 10. Since the rotation axis between the first rotating member 30 and the base 10 and the rotation axis between the second rotating member 40 and the base 10 do not coincide, the connecting member 50 and the supporting member 60 rotatably connected to the connecting member 50 can slide in a direction away from the base 10 when the first rotating member 30 and the second rotating member 40 rotate relative to the base 10. Therefore, under the cooperation of the rotation of the second rotating member 40 relative to the base 10 and the sliding of the supporting member 60 in a direction away from the base 10, the position of the rolling shaft 43 in the rolling groove 620 changes, moving from the first stop end 621 to the second stop end 622, or the rolling shaft 43 rolls from the lower right to the upper left in the rolling groove 620, thereby changing the rotation axis between the supporting member 60 and the connecting member 50 and the position between the rolling shaft 43, so that the supporting member 60 rotates relative to the connecting member 50. Finally, when the folding device 2 is in the folded state, the two support members 60 cooperate with the base 10 to enclose a teardrop-shaped receiving space 1 a.

[0136] When the folding device 2 is in the process of changing from the folding state to the unfolding state, the connecting member 50 rotates in the opposite direction relative to the base 10, driving the first rotating member 30 and the second rotating member 40 to rotate in the opposite direction relative to the base 10. Since the rotation axis between the first rotating member 30 and the base 10 and the rotation axis between the second rotating member 40 and the base 10 do not coincide, the connecting member 50 and the supporting member 60 rotatably connected to the connecting member 50 can slide in the direction close to the base 10 when the first rotating member 30 and the second rotating member 40 rotate relative to the base 10. Therefore, under the cooperation of the rotation of the second rotating member 40 relative to the base 10 and the sliding of the supporting member 60 in the direction close to the base 10, the position of the rolling shaft 43 in the rolling groove 620 changes, moving from the second stop end 622 to the first stop end 621, or the rolling shaft 43 rolls from the upper left to the lower right in the rolling groove 620, thereby changing the rotation axis between the supporting member 60 and the connecting member 50 and the position between the rolling shaft 43, so that the supporting member 60 rotates in the opposite direction relative to the connecting member 50. Finally, when the folding device 2 is in the unfolded state, the two support members 60 are disposed on opposite sides of the base 10 .

[0137] In addition, in other embodiments, the positions of the first stop end 621 and the second stop end 622 may be designed so that the support member 60 does not rotate relative to the connecting member 50. Therefore, when the folding device 2 is in the folded state, the distance between the two support members 60 is equal, and the folding device 2 forms a U-shaped receiving space 1a.

[0138] In this embodiment, the rolling groove 620 further has a first connecting portion 623 connecting the first stop end 621 and the second stop end 622, and the first connecting portion 623 protrudes in a direction away from the support surface 610. The rolling groove 620 is a groove with a certain length, so the rolling groove 620 has a first connecting portion 623 connecting the first stop end 621 and the second stop end 622 in addition to the first stop end 621 and the second stop end 622. The rolling shaft 43 can be located in the first connecting portion 623 in other states except the unfolded state and the folded state. In this embodiment, the first connecting portion 623 can be convex in a direction away from the support surface 610, which can also be understood as the shape of the first connecting portion 623 being an arc, and the arc is convexly arranged in a direction away from the support surface 610, so that the position of the rolling shaft 43 in the rolling groove 620 during the entire movement process can be controlled, thereby controlling the positional relationship between the rotation axis between the support member 60 and the connecting member 50 and the rolling shaft 43, so that the support member 60 is rotated to form a teardrop shape in the folded state. Furthermore, the arc-shaped rolling groove 620 can make the rolling of the rolling shaft 43 smoother, thereby improving the smoothness and stability of the movement of the folding device 2 .

[0139] Of course, in other embodiments, the shape of the first connecting portion 623 may also be a straight line, or other shapes, as long as the positions of the first stop end 621 and the second stop end 622 satisfy the above positional relationship.

[0140] In this embodiment, the rolling groove 620 further has a second connecting portion 624 connecting the first connecting portion 623 and the first stop end 621, and the extension direction of the second connecting portion 624 is parallel to the support surface 610. In addition to the first stop end 621, the second stop end 622, and the first connecting portion 623, the rolling groove 620 may also have a second connecting portion 624 connecting the first connecting portion 623 and the first stop end 621, that is, the second connecting portion 624 is further provided between the first connecting portion 623 and the first stop end 621. In other words, when the folding device 2 is in the process of changing from the unfolded state to the folded state, the rolling shaft 43 does not move directly from the first stop end 621 to the first connecting portion 623, but first moves to the second connecting portion 624, and then moves to the first connecting portion 623.

[0141] In this embodiment, the extension direction of the second connecting portion 624 can be parallel to the supporting surface 610, that is, the extension direction of the second connecting portion 624 is horizontal, so that when the folding device 2 is in the unfolded state, the horizontal second connecting portion 624 can be used to support the rolling shaft 43, and the second connecting portion 624 can be used to achieve buffering, thereby preventing the rolling shaft 43 from moving from the first stop end 621 to the arc-shaped first connecting portion 623 by itself, thereby improving the stability of the folding device 2. In addition, the horizontally arranged second connecting portion 624 can also reduce the gap between the rolling shaft 43 and the rolling groove 620, thereby preventing the existence of a virtual position.

[0142] In this embodiment, the folding device 2 further includes a synchronization mechanism, which includes a plurality of teeth disposed on at least a portion of the periphery of the second rotating member 40, and a plurality of synchronization members rotatably connected to the base 10. The left and right sides of the folding device 2 can move synchronously and in opposite directions through the synchronization mechanism shell, thereby improving the consistency of the folding device 2.

[0143] Please refer to Fig.36 In this embodiment, the support member 60 and the connecting member 50 are connected by the third arc rail 530 and the third arc groove 630, the third arc rail 530 is provided at one of the support member 60 and the connecting member 50, and the third arc groove 630 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 530 and the third arc groove 630 in this embodiment, the third arc rail 530 is provided at one of the support member 60 and the connecting member 50, and the third arc groove 630 is provided at the other of the support member 60 and the connecting member 50. For example, when the third arc rail 530 is provided at the support member 60, the third arc groove 630 is provided at the connecting member 50. When the third arc groove 630 is provided at the support member 60, the third arc rail 530 is provided at the connecting member 50. This embodiment is only schematically described by taking the third arc groove 630 provided on the support member 60 and the third arc rail 530 provided on the connecting member 50 .

[0144] Specifically, the support member 60 includes a support portion 61 and a rotating portion 63, wherein the support portion 61 is used to support the flexible screen 90 when the folding device 2 is applied to the electronic device 1. Therefore, the support portion 61 has a support surface 610 for supporting the flexible screen 90, that is, the upper surface of the support portion 61 is the support surface 610. The rotating portion 63 is arranged on the side of the support portion 61 away from the support surface 610, that is, the rotating portion 63 is farther away from the flexible screen 90 than the support portion 61. A circular arc groove body is provided on the side of the rotating portion 63 close to the connecting member 50, and the groove body is the third circular arc groove 630. A circular arc block body is provided on the side of the connecting member 50 close to the rotating portion 63, and the block body is the third circular arc rail 530. The third circular arc rail 530 can be arranged in the third circular arc groove 630, and the axis of the third circular arc groove 630 is colinear with the axis of the third circular arc rail 530, so that the rotating portion 63 of the support member 60 can rotate relative to the connecting member 50. As for the size and curvature of the third arc groove 630 and the third arc rail 530, 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 the present embodiment can make the support member 60 rotate relative to the connecting member 50 by changing the position between the rotation axis between the support member 60 and the connecting member 50 and the rolling axis 43. Therefore, the design of the arc groove and the arc rail can make the position of the rotation axis inside the connecting member 50 or outside the connecting member 50. By adjusting the size and curvature of the third arc groove 630 and the third arc rail 530, the position and shape of the rolling axis 43 and the rolling groove 620 can be better designed, so that the support member 60 can rotate relative to the connecting member 50. Of course, in other embodiments, the third arc rail 530 can also be provided on the support member 60, and the third arc groove 630 can also be provided on the connecting member 50.

[0145] Optionally, in one embodiment, the connecting member 50 may have a third circular arc rail 530, and the third circular arc rail 530 is disposed on one side of the connecting member 50. Correspondingly, the supporting member 60 has a rotating portion 63 and a third circular arc groove 630. In another embodiment, the connecting member 50 may have two third circular arc rails 530, and the two third circular arc rails 530 are disposed on opposite sides of the connecting member 50. Correspondingly, the supporting member 60 has two rotating portions 63 and a third circular arc groove 630. This embodiment is only schematically described by taking the connecting member 50 having two third circular arc rails 530 and the supporting member 60 having two rotating portions 63 and a third circular arc groove 630.

[0146] Please refer to Fig.37In this embodiment, the first rotating member 30 and the support member 60 are connected by a constraint shaft 350 and a constraint groove 640. The constraint shaft 350 is provided on one of the first rotating member 30 and the support member 60, and the constraint groove 640 is provided on the other of the first rotating member 30 and the support member 60. The constraint shaft 350 and the constraint groove 640 can cooperate with each other to prevent the support member 60 from excessively rotating relative to the first rotating member 30 during the movement of the folding device 2, thereby warping and subsequently affecting the folding of the flexible screen 90. In other words, in this embodiment, a virtual constraint is added between the first rotating member 30 and the first rotating member 30 to limit the movement trajectory of the inclined plate, but the constraint shaft 350 and the constraint groove 640 do not affect the degree of freedom of the folding device 2. In this embodiment, the constraint shaft 350 is provided on the first rotating member 30 and the constraint groove 640 is provided on the support member 60 for schematic illustration. Of course, in other embodiments, the constraint shaft 350 can also be provided on the support member 60, and the constraint groove 640 can be provided on the first rotating member 30.
