Description
Technical Field
[0001] The present application relates to the technical field of electronic products, and in particular to a foldable electronic device. Background Art
[0002] With the development of science and technology, various electronic devices have become indispensable products in daily life and production. Among them, foldable electronic devices have gradually become a development trend due to their advantages of large display area and easy portability.
[0003] Foldable electronic devices generally have two states: folded and unfolded. In the folded state, they are easy to carry. In the unfolded state, they offer a large display area and are very convenient to use. To ensure a flat display, the optimal unfolding angle of a foldable electronic device in the unfolded state should be 180 degrees.
[0004] However, current foldable electronic devices can only be tested for their unfolding angles after the finished product is assembled. If the unfolding angle error of the foldable electronic device is found to be large at this time, it can only be scrapped, which often results in huge waste. Summary of the Invention
[0005] The present application provides a foldable electronic device. After the finished product is assembled, if the test finds that the unfolding angle error is large, the unfolding angle can be adjusted, and the finished product with the large unfolding angle error does not need to be scrapped, thus saving resources.
[0006] An embodiment of the present application provides a foldable electronic device, comprising: a first housing, a second housing, and a rotation mechanism, wherein the rotation mechanism is connected between the first housing and the second housing to achieve a rotational connection between the first housing and the second housing. The foldable electronic device also includes a display screen, which is disposed between the first housing, the second housing, and the rotation mechanism.
[0007] The foldable electronic device has an unfolded state and a folded state. When the foldable electronic device is in the folded state, the first and second shells are stacked along the thickness direction of the foldable electronic device, and the display screen is in a bent state. When the foldable electronic device is in the unfolded state, the first and second shells are arranged in sequence along the width direction of the foldable electronic device, and the display screen is in an unfolded state.
[0008] The rotating mechanism includes a first swing arm, a second swing arm, a bearing base and an adjusting member.
[0009] The supporting base is arranged between the first shell and the second shell, and one side of the first swing arm is rotatably connected to the first shell, and the other side of the first swing arm is slidably connected to the supporting base. Specifically, the first swing arm includes a first rotating part and a first sliding part that are arranged and connected in sequence along the width direction of the foldable electronic device, the first rotating part is rotatably connected to the first shell via a first connecting shaft, and the first sliding part is slidably connected to the supporting base. One side of the second swing arm is rotatably connected to the second shell, and the other side of the second swing arm is slidably connected to the supporting base. Specifically, the second swing arm includes a second rotating part and a second sliding part that are arranged and connected in sequence along the width direction of the foldable electronic device, the second rotating part is rotatably connected to the second shell via a second connecting shaft, and the second sliding part is slidably connected to the supporting base.
[0010] The adjusting member includes an inclined surface extending along the thickness direction of the foldable electronic device and inclined relative to the width direction of the foldable electronic device. The adjusting member is disposed on the supporting base. When the foldable electronic device is in the unfolded state, the adjusting member is located between the first swing arm and the second swing arm along the width direction of the foldable electronic device, and the first swing arm and the second swing arm both abut the inclined surface. The adjusting member is configured to maintain a flattened state between the first swing arm and the second swing arm. Specifically, a first abutting end is provided at an end of the first sliding portion distal from the first rotating portion, and a second abutting end is provided at an end of the second sliding portion distal from the second rotating portion. The first abutting end and the second abutting end are spaced opposite each other along the width direction of the foldable electronic device. The adjusting member is disposed within the space between the first abutting end and the second abutting end, and the first abutting end and the second abutting end respectively abut the inclined surface of the adjusting member. When the foldable electronic device is in the unfolded state, the adjusting member maintains the first swing arm and the second swing arm in a flattened state. It is understood that the flattened state refers to a state in which the first swing arm and the second swing arm form a substantially 180-degree angle, thereby forming a substantially 180-degree angle between the first housing and the second housing.
[0011] By setting up an adjustment member, and after the first shell, second shell, and rotating mechanism of the foldable electronic device are assembled, but before the display screen is assembled, the foldable electronic device is essentially in a finished product. Next, the unfolding angle of the foldable electronic device can be tested. If the test finds that the unfolding angle error is large, the angle between the first swing arm and the second swing arm can be adjusted using the inclined surface of the adjustment member so that the angle between the first swing arm and the second swing arm is 180 degrees, and the angle between the first shell and the second shell is also 180 degrees. In other words, the angle between the first swing arm and the second swing arm can be adjusted after the foldable electronic device is assembled, without having to scrap the finished product with a large unfolding angle error, thus saving resources.
[0012] In some embodiments, the adjustment member includes an adjustment section, and the width of the adjustment section gradually increases along the height direction of the adjustment member; the height direction of the adjustment member is parallel to the thickness direction of the foldable electronic device, and the width direction of the adjustment section is parallel to the width direction of the foldable electronic device; the first swing arm and the second swing arm both abut the outer peripheral surface of the adjustment section, and the outer peripheral surface constitutes an inclined surface.
[0013] During assembly of a foldable electronic device, after the first and second housings and the rotating mechanism are assembled, but before the display screen is assembled, if testing indicates that the unfolded angle between the first and second housings is too large or too small, the inclined surface of the adjustment section can be used to simultaneously rotate the first and second swing arms, thereby changing the unfolded angle between the first and second swing arms. This method utilizes the width of the adjustment section to adjust the unfolded angle between the first and second swing arms, resulting in a simple structure and easy operation.
[0014] In some embodiments, the adjustment member is capable of moving along a first direction to reduce the expansion angle between the first swing arm and the second swing arm; the adjustment member is capable of moving along a second direction to increase the expansion angle between the first swing arm and the second swing arm; the first direction is parallel to the thickness direction of the foldable electronic device; the second direction is parallel to the thickness direction of the foldable electronic device and is opposite to the first direction.
[0015] Specifically, when the adjustment member moves in a first direction, the adjustment section applies a first force to the first swing arm and a second force to the second swing arm. The first force rotates the first swing arm in a first rotational direction, while the second force rotates the second swing arm in a second rotational direction, thereby reducing the spread angle between the first and second swing arms. The first and second rotational directions are opposite. Simply moving the adjustment member in the first direction can quickly reduce the spread angle between the first and second swing arms, resulting in high adjustment efficiency.
[0016] The first acting force can be decomposed into a first, leftward driving force and a second, downward driving force. While the first driving force pushes the first swing arm leftward, the second driving force pushes the first swing arm downward, causing the first swing arm to move both leftward and downward simultaneously, thereby rotating the first swing arm clockwise. Similarly, the second acting force can be decomposed into a third, rightward driving force and a fourth, downward driving force. While the third driving force pushes the second swing arm rightward, the fourth driving force pushes the second swing arm downward, causing the second swing arm to move both rightward and downward simultaneously, thereby rotating the second swing arm counterclockwise. As the first swing arm rotates clockwise, the second swing arm rotates counterclockwise, reducing the deployed angle between the first and second swing arms, ultimately reducing the deployed angle between the first and second shells.
[0017] When the adjustment member moves in the second direction, the first force applied by the adjustment section to the first swing arm decreases, and the second force applied by the adjustment section to the second swing arm decreases. The first swing arm rotates in the second rotational direction, and the second swing arm rotates in the first rotational direction, increasing the deployed angle between the first and second swing arms. Simply moving the adjustment member in the second direction quickly increases the deployed angle between the first and second swing arms, resulting in highly efficient adjustment.
[0018] The first force applied by the adjustment section to the first swing arm decreases, and simultaneously, the second force applied by the adjustment section to the second swing arm decreases. At this point, the first swing arm simultaneously moves rightward and upward, meaning it rotates counterclockwise. Simultaneously, the second swing arm simultaneously moves leftward and upward, meaning it rotates clockwise. As the first swing arm rotates counterclockwise, the second swing arm rotates clockwise, increasing the deployed angle between the first and second swing arms, ultimately increasing the deployed angle between the first and second housings.
[0019] In some embodiments, the adjustment section is shaped like a truncated cone, and the adjustment member can rotate along its height to move the adjustment section along the thickness of the foldable electronic device. By configuring the adjustment section in a truncated cone shape, the outer circumference of the adjustment member becomes an inclined surface. This allows the adjustment section to be moved along the thickness of the foldable electronic device using a threaded connection coupled with rotation, resulting in a simple structure and easy operation.
[0020] In some embodiments, the adjustment section is in the shape of an isosceles trapezoid. The inclined surface includes a first inclined surface and a second inclined surface, the first inclined surface and the second inclined surface are opposite to each other along the width direction of the adjustment member, the first swing arm abuts the first inclined surface, and the second swing arm abuts the second inclined surface.
[0021] In some embodiments, the adjustment member further includes a connecting section that is fixedly connected to the adjustment section along the thickness direction of the foldable electronic device. The connecting section is connected to the support base. This ensures a secure connection between the adjustment member and the support base, and the connecting section is threadedly connected to the support base, allowing the adjustment member to be moved in the first direction or the second direction by twisting the adjustment member, thereby increasing operational convenience.
[0022] In some embodiments, the adjusting member further includes an operating section, which is fixed to an end of the adjusting member facing away from the connecting section. The operating section is connected to the supporting base. The operating section can be operated manually or with the aid of a tool by an operator to smoothly move the adjusting member in the first direction or the second direction, further enhancing operational convenience.
[0023] In some embodiments, an operating slot is provided at the end of the operating section facing away from the adjustment section. The operating slot is for inserting a tool. The operating slot may be a cross slot. The operating slot allows an operator to rotate the adjustment member using a tool such as a screwdriver, thereby moving the adjustment member in the first direction or the second direction, thereby simplifying operation and improving adjustment efficiency.
[0024] In some embodiments, the supporting base includes an axis cover, a mounting seat and a support plate. Along the thickness direction of the foldable electronic device, the support plate, the mounting seat and the axis cover are fixedly connected in sequence, and there is an installation gap between the support plate and the mounting seat.
[0025] The first swing arm is slidably connected to the mounting base, with the end of the first swing arm located within the mounting gap. The second swing arm is slidably connected to the mounting base, with the end of the second swing arm located within the mounting gap. The adjustment section is located within the mounting gap, the connecting section is connected to the mounting base, and the operating section is connected to the support plate.
[0026] In some embodiments, the support plate is provided with a mounting hole, and the operating section is located in the mounting hole. The side surface of the support plate facing away from the mounting seat is used to support the display screen. The operating section is arranged inside the mounting hole to prevent the operating section from squeezing the display screen. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the first display portion 310 is mounted on the first housing 210, and the second display portion 320 is mounted on the second housing 220. The rotation mechanism 100 and the third display portion 330 are arranged opposite each other to achieve bending of the display screen 300. The width of the third display portion 330 along the X-axis can be greater than or equal to the width of the rotation mechanism 100.
[0051] The rotating mechanism 100 enables the main body 200 to switch between a folded state and an unfolded state. Specifically, the rotating mechanism 100 also has a folded state and an unfolded state. When the rotating mechanism 100 is in the folded state, the foldable electronic device 1000 is in the folded state.

The swing arm assemblies 20 can be two, three, four, or five, etc. Multiple swing arm assemblies 20 are mounted on the support base 10 in a sequentially spaced manner along the Y-axis.
[0055] Please refer to Figure 7 , Figure 7 yes Figure 6 : A schematic diagram of the partial structure of the supporting base 10 of the rotating mechanism 100 is shown in FIG. The supporting base 10 includes a shaft cover 11, a mounting seat 12, and a support plate 13. Along the Z-axis direction, the support plate 13, the mounting seat 12, and the shaft cover 11 are fixedly connected in sequence, and a mounting gap 14 is provided between the support plate 13 and the mounting seat 12. The mounting seat 12 can be fixed to the shaft cover 11 by fasteners, etc., and then the support plate 13 is fixed to the mounting seat 12 by fasteners, etc. When the foldable electronic device 1000 is in the unfolded state, the shaft cover 11 is located inside the first shell 210 and the second shell 220 and is in a hidden state. When the foldable electronic device 1000 is in the folded state, the shaft cover 11 is exposed relative to the first shell 210 and the second shell 220 and serves as the exterior component of the foldable electronic device 1000. The side surface of the support plate 13 facing away from the mounting seat 12 is used to support the third display portion 330 of the display screen 300.

[0059] For some examples, please refer to Figure 9 , Figure 9 yes Figure 6 The schematic diagram of the structure of the adjustment member 30 of the rotating mechanism 100 is shown in FIG. The adjustment member 30 includes an operating section 31, an adjustment section 32, and a connecting section 33. The operating section 31, the adjustment section 32, and the connecting section 33 are coaxially connected in sequence along the Z-axis. The adjustment section 32 is shaped like a truncated cone and includes a large-diameter end 321 and a small-diameter end 322 that face each other along the Z-axis, as well as an outer peripheral surface connecting the large-diameter end 321 and the small-diameter end 322. The outer peripheral surface of the adjustment section 32 is an inclined surface 323 that extends along the Z-axis and is inclined relative to the X-axis. The operating section 31 is connected to the large-diameter end 321 of the adjustment section 32, and the outer diameter of the operating section 31 is the same as that of the large-diameter end 321 of the adjustment section 32. The connecting section 33 is connected to the small-diameter end 322 of the adjustment section 32, and the outer diameter of the connecting section 33 is the same as that of the small-diameter end 322 of the adjustment section 32. The connecting section 33 may be a threaded section. That is, the outer diameter of the adjustment section 32 gradually decreases from the operating section 31 to the connecting section 33. An operating slot 34, which can be a cross-shaped slot, is provided at the end of the operating section 31 facing away from the adjustment section 32. The operating section 31 and the operating slot 34 facilitate the operator's use of tools to move the adjustment member 30. The adjustment section 32 is used to adjust the angle between the first swing arm 21 and the second swing arm 22, while the connecting section 33 connects the adjustment member 30 to the support base 10.
[0060] For some examples, please refer to Figure 10 and Figure 11 , Figure 10 yes Figure 3 A schematic diagram of the enlarged structure, Figure 11 yes Figure 3A partial cross-sectional view of the main body is shown in FIG. When the foldable electronic device 1000 is in the unfolded state, the first housing 210 and the second housing 220 are arranged sequentially along the X-axis, and the first receiving groove 211 and the second receiving groove 221 are connected to form a receiving groove. The rotating mechanism 100 is installed in the receiving groove, the first connecting shaft 40 is fixed to the first mounting block 212, and the second connecting shaft 41 is fixed to the second mounting block 222. The axial directions of the first connecting shaft 40 and the second connecting shaft 41 are both parallel to the Y-axis.
[0061] The first swing arm 21 and the second swing arm 22 are both mounted on the support base 10. One side of the first swing arm 21 is rotatably connected to the first housing 210, while the other side of the first swing arm 21 is slidably connected to the support base 10. One side of the second swing arm 22 is rotatably connected to the second housing 220, while the other side of the second swing arm 22 is slidably connected to the support base 10. Furthermore, the first swing arm 21 and the second swing arm 22 are symmetrically arranged along the Y-axis, with the first abutting end 25 of the first swing arm 21 and the second abutting end 28 of the second swing arm 22 spaced apart from each other along the X-axis. Specifically, the first rotating portion 23 is rotatably connected to the first connecting shaft 40, the first sliding portion 24 is mounted in the first sliding groove 15, and the second sliding portion 27 can slide within the first sliding groove 15. The second rotating portion 26 is rotatably connected to the second connecting shaft 41, and the second sliding portion 27 is mounted in the second sliding groove 16, and can slide within the second sliding groove 16.
[0062] When the rotating mechanism 100 is in the deployed state, the first swing arm 21 and the second swing arm 22 form a 180-degree angle, resulting in a 180-degree angle between the first housing 210 and the second housing 220. When the rotating mechanism 100 switches from the deployed state to the folded state, the first swing arm 21 and the second swing arm 22 both rotate approximately 110 degrees. When the rotating mechanism 100 is in the folded state, the first swing arm 21 and the second swing arm 22 form a 20-degree angle, and the first housing 210 and the second housing 220 form a 0-degree angle.
[0063] When the rotating mechanism 100 is in the deployed state, if the angle between the first swing arm 21 and the second swing arm 22 deviates significantly from 180 degrees, for example, if the angle between the first swing arm 21 and the second swing arm 22 is 195 degrees, then the deployed angle of the first swing arm 21 and the second swing arm 22 is considered too large. For another example, if the angle between the first swing arm 21 and the second swing arm 22 is 165 degrees, then the deployed angle of the first swing arm 21 and the second swing arm 22 is considered too small. Whether the deployed angle is too large or too small, the display screen 300 will bend, resulting in poor display quality.
[0064] In this embodiment, to address the issue of the first and second swing arms 21, 22 being deployed at an excessively large or small angle, each swing arm assembly 20 is provided with an adjustment member 30. Specifically, the adjustment member 30 is mounted on the supporting base 10 such that its height is parallel to the Z-axis and its width is parallel to the X-axis. Along the X-axis, the adjustment member 30 is positioned between the first and second swing arms 21, 22, and both abut against the inclined surface 323 of the adjustment member 30. The adjustment member 30 maintains a flattened state between the first and second swing arms 21, 22. This flattened state refers to a 180-degree angle (including tolerances) between the first and second swing arms 21, 22, and a 180-degree angle (including tolerances) between the first and second housings 210, 220. In other words, when the foldable electronic device 1000 is deployed, the adjustment member 30 can be used to adjust the deployed angle between the first and second swing arms 21, 22.
[0065] In other embodiments, the adjusting members 30 may be provided for only some of the swing arm assemblies 20, while other swing arm assemblies 20 may not be provided with the adjusting members 30. For example, the foldable electronic device 1000 may include four swing arm assemblies 20, two of which may be provided with the adjusting members 30, while the other two may not be provided with the adjusting members 30.
[0066] By setting the adjustment member 30, and after the first shell 210, the second shell 220 and the rotating mechanism 100 of the foldable electronic device 1000 are assembled, and before the display screen 300 is assembled, the foldable electronic device 1000 is basically in a finished product state. Next, the unfolding angle of the foldable electronic device 1000 can be tested. If the test finds that the unfolding angle error is large, the adjustment member 30 can be used to adjust the angle between the first swing arm 21 and the second swing arm 22 so that the angle between the first swing arm 21 and the second swing arm 22 is 180 degrees. In other words, the angle between the first swing arm 21 and the second swing arm 22 can be adjusted after the foldable electronic device 1000 is assembled, without having to scrap the finished product with a large unfolding angle error, saving resources.
[0067] Specifically, the connecting section 33 of the adjusting member 30 extends into the connecting hole 17 of the mounting base 12 and is threadedly engaged with the connecting hole 17. The adjusting section 32 of the adjusting member 30 is located within the mounting gap 14 of the supporting base 10 and between the first abutting end 25 of the first swing arm 21 and the second abutting end 28 of the second swing arm 22. The first abutting end 25 and the second abutting end 28 respectively abut the inclined surface 323 of the adjusting section 32. The operating section 31 of the adjusting member 30 is connected to the support plate 13. Specifically, the operating section 31 passes through the support plate 13 and is located within the mounting hole 18 of the support plate 13. In other words, the end of the operating section 31 facing away from the adjusting section 32 is exposed relative to the support plate 13. The end of the operating section 31 facing away from the adjustment section 32 is flush with the top surface of the support plate 13, or the end of the operating section 31 facing away from the adjustment section 32 is lower than the top surface of the support plate 13, that is, the end of the operating section 31 facing away from the adjustment section 32 is hidden inside the mounting hole 18. This prevents the operating section 31 from protruding out of the mounting hole 18, preventing the operating section 31 from pushing against the display screen 300 and causing deformation of the display screen 300.
[0068] When assembling the foldable electronic device 1000, after the first shell 210, the second shell 220 and the rotating mechanism 100 are assembled, and before the display screen 300 is assembled, if testing shows that the expansion angle between the first shell 210 and the second shell 220 is too large or too small, the adjustment section 32 can push the first swing arm 21 and the second swing arm 22 to rotate simultaneously, so that the expansion angle between the first swing arm 21 and the second swing arm 22 changes.
[0069] Specifically, if testing indicates that the deployed angle between the first housing 210 and the second housing 220 is too large, the adjustment member 30 can be driven to move in a first direction, specifically the negative Z-axis direction, thereby reducing the deployed angle between the first swing arm 21 and the second swing arm 22. Specifically, due to the presence of the inclined surface 323, when the adjustment member 30 moves downward, the adjustment section 32 applies a first force to the first swing arm 21 and a second force to the second swing arm 22. The first force causes the first swing arm 21 to rotate in a first rotational direction. At this time, the first rotating portion 23 rotates around the first connecting axis 40 while the first sliding portion 24 slides within the first sliding groove 15. The first rotational direction can be clockwise, and the first swing arm 21 will drive the first housing 210 to rotate in the first rotational direction. The second force causes the second swing arm 22 to rotate in a second rotational direction. At this time, the second rotating portion 26 rotates around the second connecting axis 41 while the second sliding portion 27 slides within the second sliding groove 16. The second rotation direction can be counterclockwise, and the second swing arm 22 will drive the second shell 220 to rotate synchronously along the second rotation direction. At this time, the expansion angle between the first swing arm 21 and the second swing arm 22 is reduced, and the expansion angle between the first shell 210 and the second shell 220 is synchronously reduced.
[0070] For details, please refer to Figure 12 , Figure 12 yes Figure 3, a partial structural diagram of the main body is shown in FIG. A tool such as a screwdriver can be inserted into the operating slot 34 of the adjustment member 30, and then the screwdriver can be turned, causing the screwdriver to drive the adjustment member 30 to rotate. At this time, the connecting section 33 rotates within the connecting hole 17. Because the connecting section 33 and the connecting hole 17 are threaded, the thread allows the connecting section 33 to gradually move downward while rotating, driving the adjustment section 32 downward. The outer diameter of the portion where the adjustment section 32 abuts the first and second swing arms 21 and 22 gradually increases, and the adjustment section 32 gradually pushes against the first and second swing arms 21 and 22, applying a first force F1 to the first swing arm 21 and a second force F2 to the second swing arm 22. The directions of the first and second forces F1 and F2 are both perpendicular to the inclined surface 323 of the adjustment section 32. The first force F1 can be decomposed into a leftward first driving force F11 and a downward second driving force F12. While the first driving force F11 pushes the first swing arm 21 leftward, the second driving force F12 pushes the first swing arm 21 downward. The first swing arm 21 simultaneously moves leftward and downward, i.e., the first swing arm 21 rotates clockwise. At this time, the first rotating portion 23 rotates about the first connecting shaft 40 while the first sliding portion 24 slides within the first sliding groove 15. Similarly, the second force F2 can be decomposed into a rightward third driving force F21 and a downward fourth driving force F22. While the third driving force F21 pushes the second swing arm 22 rightward, the fourth driving force F22 pushes the second swing arm 22 downward. The second swing arm 22 simultaneously moves rightward and downward, i.e., the second swing arm 22 rotates counterclockwise. At this time, the second rotating portion 26 rotates about the second connecting shaft 41 while the second sliding portion 27 slides within the second sliding groove 16.
[0071] When the first swing arm 21 rotates clockwise, the second swing arm 22 rotates counterclockwise, and the deployment angle between the first swing arm 21 and the second swing arm 22 decreases, thereby eventually reducing the deployment angle between the first shell 210 and the second shell 220.
[0072] Similarly, if testing indicates that the deployed angle between the first housing 210 and the second housing 220 is too small, the adjustment member 30 can be driven to move in a second direction, specifically the positive Z-axis direction, thereby increasing the deployed angle between the first swing arm 21 and the second swing arm 22. Specifically, due to the presence of the inclined surface 323, when the adjustment member 30 moves upward, the first force F1 applied by the adjustment section 32 to the first swing arm 21 decreases, and the second force F2 applied by the adjustment section 32 to the second swing arm 22 decreases. As the first swing arm 21 rotates in the second rotational direction, it drives the first housing 210 to rotate synchronously in the second rotational direction. As the second swing arm 22 rotates in the first rotational direction, it drives the second housing 220 to rotate synchronously in the first rotational direction. As the deployed angle between the first and second swing arms 21 and 22 increases, the deployed angle between the first and second housings 210 and 220 increases simultaneously.
[0073] In detail, a tool such as a screwdriver can be inserted into the operating slot 34 of the adjustment member 30, and then the screwdriver can be turned so that the screwdriver drives the adjustment member 30 to rotate. At this time, the connecting section 33 rotates in the connecting hole 17, and the connecting section 33 gradually moves upward, driving the adjustment section 32 to move upward. The outer diameter of the portion where the adjustment section 32 abuts the first swing arm 21 and the second swing arm 22 gradually decreases, and the first force F1 applied by the adjustment section 32 to the first swing arm 21 decreases. At the same time, the second force F2 applied by the adjustment section 32 to the second swing arm 22 decreases. At this time, the first swing arm 21 moves to the right and upward at the same time, that is, the first swing arm 21 rotates counterclockwise. Synchronously, the second swing arm 22 moves to the left and upward at the same time, that is, the second swing arm 22 rotates clockwise.
[0074] When the first swing arm 21 rotates counterclockwise, the second swing arm 22 rotates clockwise, and the deployment angle between the first swing arm 21 and the second swing arm 22 increases, thereby ultimately increasing the deployment angle between the first shell 210 and the second shell 220 .
[0075] For other embodiments, please refer to Figure 13 , Figure 13 It is a structural schematic diagram of an adjustment member 30 provided in another embodiment of the present application. The adjustment member 30 includes an operating section 31, an adjustment section 32 and a connecting section 33. Along the Z-axis direction, the operating section 31, the adjustment section 32 and the connecting section 33 are coaxially connected in sequence. The adjustment section 32 is in the shape of a truncated cone. The adjustment section 32 includes a large diameter end 321 and a small diameter end 322 opposite to each other along the Z-axis direction, and includes an inclined surface 323 connected between the large diameter end 321 and the small diameter end 322. The operating section 31 is connected to the small diameter end 322 of the adjustment section 32. The connecting section 33 is connected to the large diameter end 321 of the adjustment section 32, and the connecting section 33 can be a threaded section. An operating groove 34 is provided at the end of the operating section 31 away from the adjustment section 32.
[0076] That is, the outer diameter of the adjusting section 32 of the adjusting member 30 in this embodiment changes in the opposite direction to that of the adjusting section 32 in the above embodiment. In this embodiment, the outer diameter of the adjusting section 32 gradually increases from the operating section 31 to the connecting section 33 .
[0077] When adjusting the deployed angle between the first and second swing arms 21, 22, the adjustment member 30 moves downward, gradually reducing the outer diameter of the portion where the adjustment section 32 abuts the first and second swing arms 21, 22. At this point, the first swing arm 21 rotates counterclockwise while the second swing arm 22 rotates clockwise, increasing the deployed angle between the first and second swing arms 21, 22 and ultimately increasing the deployed angle between the first and second housings 210, 220.
[0078] As the adjustment member 30 moves upward, the outer diameter of the portion of the adjustment section 32 that contacts the first and second swing arms 21, 22 gradually increases. At this point, the first swing arm 21 rotates clockwise while the second swing arm 22 rotates counterclockwise, reducing the angle between the first and second swing arms 21, 22. Ultimately, this reduces the angle between the first and second housings 210, 220.
[0079] In some other embodiments, please refer to Figure 14 , Figure 14 This is a structural schematic diagram of an adjustment member 30 provided in another embodiment of the present application. The adjustment member 30 includes an operating section 31, an adjustment section 32, and a connecting section 33. Along the Z-axis direction, the operating section 31, the adjustment section 32, and the connecting section 33 are connected in sequence. The operating section 31 and the connecting section 33 are both in the shape of an elongated strip, and the adjustment section 32 is in the shape of an isosceles trapezoid. The inclined surface 323 of the adjustment section 32 includes a first inclined surface 324 and a second inclined surface 325. The first inclined surface 324 and the second inclined surface 325 are opposite to each other along the width direction of the adjustment member. The first swing arm abuts the first inclined surface 324, and the second swing arm abuts the second inclined surface 325. Correspondingly, the connecting hole 17 of the mounting seat 12 is set as an elongated hole, and the mounting hole 18 of the support plate 13 is set as an elongated groove.
[0080] When it is necessary to adjust the deployment angle between the first swing arm 21 and the second swing arm 22, the operating section 31 is clamped by a clamping tool, and then the adjusting member 30 is moved along the Z-axis direction. The connecting section 33 and the connecting hole 17 cooperate to guide the movement of the adjusting member 30, so that the position where the adjusting section 32 abuts against the first swing arm 21 and the second swing arm 22 is changed, thereby changing the deployment angle of the first swing arm 21 and the second swing arm 22. When the deployment angle of the first swing arm 21 and the second swing arm 22 is 180 degrees, the operating section 31 can be fixed to the support plate 13 by bonding or welding, so that the position of the adjusting member 30 is fixed.
[0081] The above are only some of the embodiments and implementations of this application. The scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
