Description

Technical Field

[0001] This application relates to the field of terminal technology, and more specifically, to a folding control mechanism with a stop function.

Background Art

[0002] As flexible display technology gradually matures, the display method of electronic devices is changing significantly. Mobile phones with foldable flexible displays, tablet computers with foldable flexible displays, wearable electronic devices with foldable flexible displays, etc. are important evolutionary directions for future intelligent electronic devices.

[0003] A flexible display is an important component of a foldable electronic device and has the characteristics of continuity and foldability. A folding control mechanism is used as an important component for implementing the folding function of a foldable electronic device. In the process of unfolding and folding a foldable electronic device, the folding control mechanism can drive the flexible display to be unfolded or folded.

[0004] In the case of a frequently used foldable electronic device, whether the electronic device can be accurately unfolded greatly affects the display effect of the content on the screen and the user experience. Therefore, how to control the angle and accuracy in the unfolded state is a problem that is currently attracting attention and needs to be solved.

Summary of the Invention

[0005] This application provides an unfolded state control mechanism. The unfolded state control mechanism can effectively reduce the relative movement between the arc-shaped arm and the installation plate by using a stop block, accurately control the angle in the unfolded state, and prevent overfolding or non-uniformity. In this way, the user experience is effectively improved and the product competitiveness is enhanced.

[0006] According to the first aspect, the present application provides a folding control mechanism. The folding control mechanism can be used in a foldable electronic device. The folding control mechanism includes a base and a first rotating assembly. The first rotating assembly is rotatably connected to the base. The first rotating assembly includes a first swing arm and a first housing fixing bracket. The first swing arm is rotatably connected to the base, and the first swing arm is slidably connected to the first housing fixing bracket. A first sliding groove is provided in the first housing fixing bracket. The first sliding groove extends in a first direction or a second direction. The first swing arm is installed in the first sliding groove and can slide in the first direction or the second direction in the first sliding groove. The first direction is the direction in which the first housing fixing bracket approaches the base, and the second direction is the direction in which the first housing fixing bracket moves away from the base. The folding control mechanism further includes a first stop block. The first stop block is configured to stop the sliding track between the first swing arm and the first housing fixing bracket in the process of folding the folding control mechanism. By using the stop block, the folding control mechanism can accurately control the folded state and the unfolded state of the foldable electronic device, thereby preventing folding at a negative angle and effectively improving the user experience.

[0007] In a possible implementation form, the first swing arm has a first opening. The first stop block passes through the first opening and contacts a first stop surface to implement stopping. The first opening is arranged to control the first stop block for controlling the unfolding angle.

[0008] In a possible implementation form, the first housing fixing bracket includes a first stop surface, and the first stop surface is used to limit the end of the first sliding groove. The first swing arm is fixed to the first stop block. The first swing arm moves in the first sliding groove in the second direction, and the first swing arm slides relative to the first housing fixing bracket until the first stop block contacts the first stop surface. The use of the first stop block can effectively control the folded state, and the folding angle can also be effectively controlled through the design of the first stop block.

[0009] In a possible implementation form, the first stop block has a protrusion, and the protrusion slides in the first sliding groove until the protrusion contacts the first stop surface. The protrusion is used to enable the first stop block to slide in the first sliding groove. Since one end of the first sliding groove is not blocked and the other end is blocked by using a physical part on the first housing fixing bracket, the sliding distance of the first stop block in the first sliding groove is effectively controlled, and the deployment angle is effectively controlled.

[0010] In a possible implementation form, the first stop block passes through the first opening and is fixed to the first swing arm by a welding method. The first swing arm and the first stop block are effectively fixed by the welding method, whereby the first swing arm and the first stop block can be fixed to form an integral body. The first swing arm is fixed together with the first stop block to control the position of the first swing arm.

[0011] In a possible implementation form, the first swing arm includes a first stop surface, and the first stop surface is located inside the end of the first opening. The first stop block is fixed to a physical part at the end of the first sliding groove on the first housing fixing bracket. The first swing arm moves in the second direction within the first sliding groove. The first swing arm slides relative to the first housing fixing bracket until the first stop block contacts the first stop surface. The first stop surface is located inside the end of the first opening of the first swing arm that is away from the base. The contact between the first stop surface and the first stop block effectively executes the stop and can prevent the first housing fixing bracket from sliding relative to the first swing arm.

[0012] In a possible implementation form, the first stop block is fixed to the first housing fixing bracket by a welding method. The welding method can ensure that the stop block and the first housing fixing bracket are fixed to form a whole.

[0013] In a possible implementation form, the folding control mechanism further includes a second rotation assembly, and the second rotation assembly is rotatably connected to the base. The second rotation assembly includes a second swing arm and a second housing fixing bracket. The second swing arm is rotatably connected to the base, and the second swing arm is slidably connected to the second housing fixing bracket. The second housing fixing bracket is provided with a second sliding groove. The second sliding groove extends in the first direction or the second direction. The second swing arm is installed in the second sliding groove and can slide in the first direction or the second direction within the second sliding groove. The first direction is the direction in which the second housing fixing bracket approaches the base, and the second direction is the direction in which the first housing fixing bracket moves away from the base. The folding control mechanism further includes a second stop block. The second stop block is configured to stop the sliding track between the second swing arm and the second housing fixing bracket in the process of folding the folding control mechanism. The implementation form of this part is the same as that of the first rotation assembly, and the two parts of the folding control mechanism can be controlled to be deployed at the same deployment angle.

[0014] In a possible implementation form, the second swing arm has a second opening, and the second stop block passes through the second opening and contacts the second stop surface to effect stopping. Here, by controlling the size of the second opening, the position and size of the second stop block can be controlled.

[0015] In a possible implementation form, the second housing fixing bracket includes a second stop surface, and the second stop surface is configured to limit an end of the second sliding groove. The second swing arm is fixed to the second stop block. The second swing arm moves in the second direction within the second sliding groove, and the second swing arm slides relative to the second housing fixing bracket until the second stop block contacts the second stop surface. The second stop block contacts the second stop surface, whereby the second stop block stops sliding. In this way, the second swing arm fixed to the second stop block also stops sliding and is connected to the second housing fixing bracket via the second stop block to form an entirety.

[0016] In a possible implementation form, the second stop block has a protrusion, and the protrusion slides within the second sliding groove until the protrusion contacts the second stop surface. The protrusion of the second stop block contacts an end of the second sliding groove, and the second stop block stops sliding and is connected to the first housing fixing bracket to form an entirety.

[0017] In a possible implementation form, the second stop block passes through the second opening and is fixed to the second swing arm by a welding method. The welding method can enable the second stop block and the second swing arm to form an entirety, whereby the second swing arm can be controlled in the stopping manner of the second stop block.

[0018] In a possible implementation form, the second swing arm includes a second stop surface, and the second stop surface is located inside the end of the second opening. The second stop block is fixed to the physical part at the end of the second sliding groove on the second housing fixing bracket. The second swing arm moves in the second direction within the second sliding groove, and the second swing arm slides relative to the second housing fixing bracket until the second stop block contacts the second stop surface. The second stop surface is located inside the end of the second opening of the second swing arm that is away from the base. The second stop surface is in contact with the second stop block. In this case, the second stop block and the second housing fixing bracket form an entirety, that is, the second swing arm contacts the second housing fixing bracket to form an entirety.

[0019] In a possible implementation form, the second stop block is fixed to the second housing fixing bracket by a welding method. With the welding method, the second stop block and the second housing fixing bracket can be connected to form an entirety.

[0020] According to a second aspect, an electronic device is provided. The electronic device includes a folding control mechanism, a first housing, a second housing, a flexible display, and the aforementioned folding control mechanism. The first housing and the second housing are respectively disposed on two opposite sides of the folding control mechanism. A first housing fixing bracket is fixed to the first housing, a first swing arm is slidably connected to the first housing fixing bracket, and a first stop block is disposed between the first housing fixing bracket and the first swing arm. A second housing fixing bracket is fixed to the second housing, a second swing arm is slidably connected to the second housing fixing bracket, and a second stop block is disposed between the second housing fixing bracket and the second swing arm. The flexible display continuously covers the first housing, the second housing, and the folding control mechanism, and the flexible display is fixed to the first housing and the second housing. The electronic device controls the folding control mechanism by fixing the first stop block in the first rotation assembly to the first swing arm, or fixing the first stop block to the first housing fixing bracket, and fixing the second stop block in the second rotation assembly to the second swing arm, or fixing the second stop block to the second housing fixing bracket. In this way, by adjusting the size of the stop block, the unfolding angle and accuracy of the folding control mechanism can be effectively improved, thereby improving the user experience.

[0027] To make the technical problems to be solved, the technical solutions used, and the technical effects achieved in the present application clearer, hereinafter, with reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be further described in detail. It is obvious that the described embodiments are only a part, not all, of the embodiments of the present application.

[0028] In the current market, there is not much research on the control of the deployment state of electronic devices with flexible displays, and most of them focus on the folding method and deployment method of flexible displays. Regarding the deployment angle, user experience in the deployed state, etc., there are not many research results in the current technical direction. Therefore, the folding control mechanism provided in this application is particularly important.

[0029] In order to improve the angle accuracy in the deployed state, further improve the specification of the sophistication of the folding mechanism, optimize the user experience, and improve the overall product competitiveness, this application provides a folding control mechanism. The details will be described below. [Embodiment 1]

[0030] To facilitate the understanding of the folding control mechanism provided in the embodiments of this application, first, the application scenario of the folding control mechanism will be described below. The folding control mechanism can be used in foldable electronic devices such as mobile phones, palmtop computers (personal digital assistants, PDAs), notebook computers, or tablet computers, but is not limited thereto. When the folding control mechanism provided in the embodiments of this application is used in an electronic device, as shown in FIG. 1a, the electronic device includes a folding control mechanism 1, two housings, and a flexible display 4 (the dashed box shown in FIG. 1a). For ease of explanation, the two housings may be referred to as the first housing 2 and Second housing 3 respectively. The folding control mechanism includes a base, a first rotation assembly 200 (shown in FIG. 1c), and a second rotation assembly 300 (shown in FIG. 1c). In addition, the first housing 2 and Second housing 3 are located on both sides of the folding control mechanism 1 and can rotate around the folding control mechanism. During use, the electronic device can be folded or deployed in different use scenarios.

[0031] In this application, the electronic device can be a foldable electronic device. In the process of switching the foldable electronic device from the unfolded state to the folded state, the flexible display 4 is always located on the outside of the electronic device. FIG. 1a shows the relative positional relationship between the folding control mechanism 1 and the two housings when the electronic device is in the folded state. In this case, the first surface of the folding control mechanism 1, the first surface of the first housing 2, and the first surface of the second housing 3 can be jointly used as the support surface of the flexible display 4. In FIG. 1, the flexible display 4 is omitted. The first surface of the folding control mechanism 1 is the surface of the folding control mechanism 1 facing the flexible display 4, the first surface of the first housing 2 is the surface of the first housing 2 facing the flexible display 4, and the first surface of the second housing 3 is the surface of the second housing 3 facing the flexible display 4. For ease of explanation, in this application, the first surface of the folding control mechanism 1 can be defined as the seating surface 1a of the folding control mechanism 1, the first surface of the first housing 2 can be defined as the first support surface 2a, and the first surface of the second housing 3 can be defined as the second support surface 3a.

[0032] Refer to FIG. 1b. FIG. 1b is a diagram showing the structure of the electronic device in the unfolded state, and FIG. 1b shows the structure of the first support surface 2a of the first housing 2 and the second support surface 3a of the second housing 3. In the unfolded state, the seating surface 1a of the folding control mechanism 1, the first support surface 2a of the first housing 2, and the second support surface 3a of the second housing 3 can be connected to form a flat support surface.

[0033] Based on this, the flexible display 4 is the seating surface 1a of the folding control mechanism 1, the first support surface 2a of the first housing 2, and the second housing 3can continuously cover the second support surface 3a. The folding control mechanism 1 is arranged corresponding to the foldable part of the flexible display 4, and the flexible display 4 can be fixed to the first support surface 2a of the first housing 2 and the second support surface 3a of the second housing 3. The connection method may be adhesion, but is not limited thereto. In this way, when the electronic device is in the unfolded state shown in FIG. 1b, the folding control mechanism 1, the first housing 2, and the second housing 3 can support the flexible display 4 flatly.

The second stop block 303 is configured to stop the sliding track between the second swing arm 302 and the second housing fixing bracket in the process of folding the folding mechanism. Above, two structures of the folding control mechanism have been briefly described. The first stop block 203 of the first rotating assembly 200 and the second stop block 303 of the second rotating assembly 300 are important components for accurately controlling the folding and unfolding by the folding rotation mechanism. In the following embodiments, the structure of the folding control mechanism and the function of the stop block will be described in detail separately. [Embodiment 2]

[0036] Based on Embodiment 1, this embodiment discloses a folding control mechanism for stopping the first swing arm 202 in a manner of fixing it to the first stop block 203 in FIG. 1c. FIG. 2a is an exploded view of the folding mechanism according to an embodiment of the present application. In the figure, the folding mechanism includes a base 100, a first rotating assembly 200, and a second rotating assembly 300. The first rotating assembly includes a first swing arm 202, a first opening 2021, a first housing fixing bracket 201, a first stop block 203, a first sliding groove 2011, and a first stop surface 2012. The second rotating assembly includes a second swing arm 302, a second opening 3021, a second housing fixing bracket 301, a second stop block 303, a second sliding groove 3011, and a second stop surface 3012. The first opening 2021 is located on the first swing arm 202, and the second opening 3021 is located on the second swing arm 302. The first rotating assembly 200 and the second rotating assembly 300 are exactly the same assembly and are distributed on both sides of the base 100. In this specification, the separate numbering of the first rotating assembly 200 and the second rotating assembly 300 is based on the positional relationship.

[0037] The architectures of the first rotating assembly and the second rotating assembly located on both sides of the base are symmetrical, and the functions of the assemblies are also consistent. Therefore, for the sake of simplicity of description, in this specification, one side is used as an example for detailed description. This embodiment of the present application mainly describes in detail the method of fixing the first swing arm 202 in FIG. 2a to the first stop block 203. As shown in FIG. 2b, FIG. 2b is a diagram showing the fixing of the first swing arm 202 to the first stop block 203. The first stop block 203 has a protrusion 2031, and the protrusion 2031 slides within the first sliding groove 2011. In addition, there is one first opening in the first swing arm 202, and the first stop block 203 passes through the first opening and contacts the first stop surface 2012, that is, the end having a physical part of the first sliding groove 2011, to achieve a stopping effect. One end of the first sliding groove 2011 is not blocked by a physical object. The other end is a physical part. The physical part is located on the first housing fixing bracket 201 and is a part of the first housing fixing bracket 203, and is configured to prevent the first stop block from continuously sliding along the first sliding groove 2011. Therefore, the length of the first sliding groove 2011 is controlled, whereby the sliding distance of the first stop block 203 within the first sliding groove 2011 can be controlled. The first stop block 203 is fixed to the first swing arm 202 by welding or hinge connection to form an entirety. FIG. 2c more clearly shows a diagram of the three-dimensional structure of the folding control mechanism. As shown in FIG. 2c, the first swing arm 202 is fixed to the first stop block 203. For the sake of distinction, here, the first swing arm 202 fixed to the first stop block 203 is called the first composite swing arm. The first composite swing arm is rotatably connected to the base 100, and the first housing fixing bracket 201 is slidably connected to the first composite swing arm, whereby the first housing fixing bracket 201 can rotate around the base 100.The first housing fixing bracket 201 is provided with a first sliding groove 2011. The first sliding groove 2011 extends in the first direction or the second direction. The first sliding groove 2011 is installed on the first composite swing arm. The first composite swing arm can slide in the first direction or the second direction within the first sliding groove 2011. The first direction indicates the direction in which the first housing fixing bracket 201 approaches the base 100, and the second direction indicates the direction in which the first housing fixing bracket 201 moves away from the base 100. In the process of the first housing fixing bracket 201 moving in the second direction, the first composite swing arm slides along the first sliding groove 2011. The first composite swing arm slides relative to the first housing fixing bracket 201. There is no contact between the first stop block 203 and the first stop surface 2012, and there is a gap in the middle. Fig. 2d is a cross-sectional view of the folding state of the folding control mechanism. There is a gap between the first stop block 203 and the first stop surface 2012. The first composite swing arm continues to slide along the first sliding groove 2011 until the first stop block 203 contacts the first stop surface 2012. The first composite swing arm and the first housing fixing bracket are clamped together. Fig. 2e is a cross-sectional view of the deployed state of the folding control mechanism. In this case, there is no gap between the first stop block 203 and the first stop surface 2012. Specifically, the first stop block 203 is in contact with the first stop surface 2012. In Fig. 2e, a part of the first stop surface 2012 overlaps with a part of the first stop block 203. In addition, the whole including the first housing fixing bracket 201 and the first composite swing arm is in the deployed state together with the base 100. [Embodiment 3]

[0038] Based on the foregoing embodiments, this embodiment discloses a folding control mechanism that implements stopping by a method of fixing the first housing fixing bracket 201 to the first stop block 203 in FIG. 1c. FIG. 3a is an exploded view of another folding mechanism according to an embodiment of the present application. In the figure, the folding mechanism includes a base 100, a first rotating assembly 200, and a second rotating assembly 300. The first rotating assembly includes a first swing arm 202, a first opening 2021, a first housing fixing bracket 201, a first stop block 203, a first sliding groove 2011, and a first stop surface 2012. The second rotating assembly includes a second swing arm 302, a second opening 3021, a second housing fixing bracket 301, a second stop block 303, a second sliding groove 3011, and a second stop surface 3012. The first opening 2021 is located on the first swing arm 202, and the second opening 3021 is located on the second swing arm 302. The first rotating assembly 200 and the second rotating assembly 300 are exactly the same assemblies and are distributed on both sides of the base 100. In this specification, the separate numbering of the first rotating assembly 200 and the second rotating assembly 300 is based on the positional relationship.

[0039] Therefore, for the sake of simplicity in the description, in this specification, one side is used as an example for detailed description. This embodiment of the present application mainly details a method of fixing the first housing fixing bracket 201 in FIG. 3a to the first stop block 203. As shown in FIG. 3b, FIG. 3b is a diagram of fixing the first housing fixing bracket 201 to the first stop block 203. The first stop block 203 includes a protrusion 2031 (shown in FIG. 2b), and the protrusion 2031 (shown in FIG. 2b) is within the first sliding groove 2011 and is fixed to the end of the first sliding groove 2011 that has a physical portion. The end of the first sliding groove 2011 that has a physical portion belongs to a part of the first housing fixing bracket 201, and the physical portion is configured to be fixed to the first stop block 203. The fixed connection may be a welding or a hinge connection. Here, the first housing fixing bracket 201 fixed to the first stop block 203 is referred to as the first composite housing fixing bracket. It should be noted that the first composite housing fixing bracket can be assembled in the following way: First, install the first housing fixing bracket 201, and then install the first swing arm 202 on the first housing fixing bracket 201. The first swing arm 202 has a first opening 2021, and the first stop block 203 passes through the first opening 2021 and is fixed to the first housing fixing bracket 201. The fixed connection can be by welding or a hinge connection to fix the first stop block 203 to the end of the first sliding groove 2011 on the first housing fixing bracket 201. FIG. 3c is a diagram of a three-dimensional structure in which the first composite housing fixing bracket is used in the folding control mechanism. The first swing arm 202 is rotatably connected to the base 100, and the first composite housing fixing bracket is slidably connected to the first swing arm 202, whereby the first housing fixing bracket 201 can rotate around the base 100. The first composite housing fixing bracket is provided with a first sliding groove 2011, the first sliding groove 2011 extends in the first direction or the second direction, the first sliding groove 2011 is installed on the first swing arm 202, and the first swing arm 202 can move in the first direction or the second direction within the first sliding groove 2011.The first direction indicates the direction in which the first composite housing fixing bracket approaches the base 100, and the second direction indicates the direction in which the first composite housing fixing bracket moves away from the base 100. In the process of the first composite housing fixing bracket moving in the second direction, the first swing arm 202 slides along the first sliding groove 2011, the first swing arm 202 slides relative to the first composite housing fixing bracket, and the first stop block 203 fixed to the first housing fixing bracket 201 passes through the first opening 2021 of the first swing arm 202 and moves together with the first swing arm 202 in the first opening 2021 in the direction approaching the first stop surface 2012.
