Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display screen assembly and display device. Background Technology

[0002] As electronic display devices become thinner, lighter, and more flexible, bendable flexible screens are increasingly being used in various terminal devices. The initial design goal of flexible screens is to allow the same display panel to display different screen sizes as needed in different application scenarios such as gaming, office work, and movie watching, while ensuring portability and storage, so as to better meet viewing and usage needs.

[0003] However, most display terminals currently using flexible screens adopt a simple folding form, which can only switch between two states: fully unfolded and fully folded. They cannot continuously adjust the effective display area according to the actual application scenario, resulting in a relatively fixed screen size, limited space utilization, and the folding parts of the screen are prone to creases or mechanical fatigue during repeated bending. Utility Model Content

[0004] The main purpose of this application is to propose a display assembly that aims to solve the technical problems of current display terminals using flexible screens being unable to continuously adjust the effective display area according to actual application scenarios, resulting in relatively fixed screen size, limited space utilization, and the screen's folding parts being prone to creases or mechanical fatigue during repeated bending.

[0005] To achieve the above objectives, the display assembly proposed in this application includes: Base; A flexible screen is rolled up to form a first screen segment and a second screen segment, the first screen segment being connected to the base; A flexible traction component is coiled to form a first traction segment and a second traction segment. The first traction segment is connected to the base, and the second traction segment is connected to the second screen segment. An adjusting member is movably connected to the base along a preset path. The adjusting member has a first actuating part and a second actuating part spaced apart. The first actuating part is clamped between the first screen segment and the second screen segment, and the second actuating part is clamped between the first traction segment and the second traction segment. When the adjusting member moves forward along the preset path, the first actuating part pushes the second screen segment to extend in a direction closer to the first screen segment. When the adjusting member moves backward along the preset path, the second actuating part pushes the second traction segment to extend in a direction closer to the first traction segment, so as to pull the second screen segment to rewind in a direction away from the first screen segment.

[0006] In one embodiment, the display assembly further includes a driving component connected to the adjusting member, the driving component being used to drive the adjusting member to move forward or backward along the preset path.

[0007] In one embodiment, the base is provided with a guide groove that extends along the preset path, and the adjusting member is slidably engaged in the guide groove; The driving assembly includes a driving roller and a rotary driving device. The driving roller is rotatably connected to the adjusting member and rolls against the wall of the guide groove. The rotary driving device is connected to the driving roller. The rotary driving device is used to drive the driving roller to rotate, thereby causing the adjusting member to slide along the preset path in the guide groove.

[0008] In one embodiment, the display screen assembly further includes a first limiting pulley, which is rotatably connected to the adjusting member. The first limiting pulley is spaced apart from the driving roller, and the first limiting pulley rolls in cooperation with the wall of the guide groove.

[0009] In one embodiment, the display assembly further includes a first drive pulley, which is rotatably connected to the first actuation part. The first drive pulley is sandwiched between the first screen segment and the second screen segment, and the first drive pulley rolls in cooperation with the first screen segment and the second screen segment.

[0010] In one embodiment, the display assembly further includes a second drive pulley, which is rotatably connected to the second actuation part. The second drive pulley is sandwiched between the first traction section and the second traction section, and the second drive pulley rolls in cooperation with the first traction section and the second traction section.

[0011] In one embodiment, the base is provided with a guide groove that extends along the preset path, and the adjusting member is slidably engaged in the guide groove; The display screen assembly also includes a second limiting pulley, which is rotatably connected to the adjusting member. The second limiting pulley is located between the second traction section and the groove wall of the guide groove, and the second limiting pulley is in rolling cooperation with the second traction section.

[0012] This application also proposes a display device comprising a display screen assembly as described above.

[0013] In one embodiment, the display device further includes an input signal source and a main control unit. The main control unit is electrically connected to the driving circuit of the flexible screen and the input signal source. The main control unit is used to acquire the content information type of the input signal source and generate a suitable target resolution and / or target refresh rate. The main control unit is also used to send the target resolution and / or target refresh rate to the driving circuit so as to control the flexible screen to display the image at the target resolution and / or target refresh rate through the driving circuit.

[0014] In one embodiment, the display device further includes a counterweight, an attitude sensing module, and a main control unit. The counterweight is movably connected to the base, and the main control unit is connected to the counterweight and the attitude sensing module. The attitude sensing module is used to detect the attitude change information of the flexible screen and send it to the main control unit; the main control unit is used to generate a corresponding displacement command based on the attitude change information, so as to control the counterweight to move to the target position through the displacement command.

[0015] The display assembly proposed in this application allows for stepless adjustment of the display area size by moving an adjustable component along a preset path, enabling the flexible screen to unfold or retract. Specifically, when the adjustable component moves forward, its first actuating part causes the second screen segment to gradually extend along the direction closer to the first screen segment, resulting in a linear increase in the area of ​​the first screen segment, which serves as the display area. This better suits scenarios such as gaming and movie watching that require large-size displays. When the adjustable component moves in the reverse direction, its second actuating part, through a flexible traction component, causes the second screen segment to gradually retract along the direction away from the first screen segment, resulting in a linear decrease in the area of ​​the first screen segment, which better meets the needs of daily office work or compact storage, improving space utilization. The screen retraction method of this solution can replace the traditional simple folding method, reducing creases and mechanical fatigue caused by repeated bending of the same part of the screen, extending the service life of the display device, and better meeting the needs of diverse application scenarios for flexible changes in display screen size.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0023] As electronic display devices become thinner, lighter, and more flexible, bendable flexible screens are increasingly being used in various terminal devices. The initial design goal of flexible screens is to allow the same display panel to display different screen sizes as needed in different application scenarios such as gaming, office work, and movie watching, while ensuring portability and storage, so as to better meet viewing and usage needs.

[0024] However, most display terminals currently using flexible screens adopt a simple folding form, which can only switch between two states: fully unfolded and fully folded. They cannot continuously adjust the effective display area according to the actual application scenario, resulting in a relatively fixed screen size, limited space utilization, and the folding parts of the screen are prone to creases or mechanical fatigue during repeated bending.

[0025] To address the aforementioned issues, this application proposes a display assembly designed to use a movable adjustment component to unfold or roll up a flexible screen, thereby achieving continuous adjustment of the display area in a dynamic manner. This reduces structural damage caused by repeated bending of the same location and better meets the diverse application scenarios' needs for flexible changes in display screen size.

[0026] Please see Figure 8 and supplementary reference Figures 1 to 3 An embodiment of this application provides a display screen assembly, including: Base 1; The flexible screen 2 is rolled up to form a first screen segment 21 and a second screen segment 22, with the first screen segment 21 connected to the base 1; The flexible traction member 3 is curled to form a first traction section 31 and a second traction section 32. The first traction section 31 is connected to the base 1, and the second traction section 32 is connected to the second screen section 22. Adjusting member 4 is movably connected to base 1 along a preset path; adjusting member 4 has a first actuating part 41 and a second actuating part 42 spaced apart, the first actuating part 41 is clamped between the first screen segment 21 and the second screen segment 22, and the second actuating part 42 is clamped between the first traction segment 31 and the second traction segment 32; when adjusting member 4 moves forward along the preset path, the first actuating part 41 pushes the second screen segment 22 to extend in the direction close to the first screen segment 21; when adjusting member 4 moves backward along the preset path, the second actuating part 42 pushes the second traction segment 32 to extend in the direction close to the first traction segment 31, so as to pull the second screen segment 22 to rewind in the direction away from the first screen segment 21.

[0027] In this embodiment, base 1 can refer to a fixed part of the display terminal that does not move during screen size adjustment. Figures 1 to 3 As shown in the example, the base 1 is the back plate structure on the display terminal. The back plate structure is used to connect the support base to provide an installation and support foundation for movable components such as the flexible screen 2, flexible traction component 3, and adjustment component 4.

[0028] The adjusting component 4 can be configured as a strip-shaped or plate-shaped structure and connected to the corresponding guide structure of the base 1 through a sliding fit or other means. The adjusting component 4 can be driven manually or by a driving device to move relative to the base 1 along a preset path. For ease of explanation of the adjustment process, it is now defined that the preset path extends along the left and right direction of the display terminal, and that the adjusting component 4 moving to the right along the preset path is a forward movement, and moving to the left is a reverse movement; this setting will be used in the following description and will not be repeated.

[0029] Based on the above settings, the adjusting member 4 is located on the front side of the base 1, the first actuating part 41 of the adjusting member 4 should refer to the right side of the adjusting member 4, and the second actuating part 42 of the adjusting member 4 should refer to the left side of the adjusting member 4.

[0030] The flexible screen 2 can be a flexible OLED (Organic Light-Emitting Diode) panel; the flexible screen 2 is laid in the left and right direction, and the flexible screen 2 is located in front of the adjusting member 4. The left half of the flexible screen 2 forms the first screen segment 21. The left side of the first screen segment 21 is connected and fixed to the left side of the base 1 extending forward. The right half of the flexible screen 2 is folded backward around the first actuating part 41 to the rear of the first screen segment 21 to form the second screen segment 22. In this way, the first actuating part 41 will be located on the concave side of the right folded part of the flexible screen 2.

[0031] The first screen segment 21 is set as the display area. The side of the first screen segment 21 facing forward (i.e. the side facing away from the second screen segment 22) faces the user and is used for displaying the image; the second screen segment 22 is rolled up behind the first screen segment 21 and does not display the image.

[0032] It should be noted that the ranges of the first screen segment 21 and the second screen segment 22 are not fixed. Taking the first actuating part 41 as the dividing point, the portion in front of the first actuating part 41 is called the first screen segment 21, and the portion behind the first actuating part 41 is called the second screen segment 22. It can be understood that when the second screen segment 22 extends in a direction closer to the first screen segment 21 under the action of an external force, the portion of the second screen segment 22 extending to the front of the first actuating part 41 will become the first screen segment 21, and the area of ​​the display area will increase accordingly as the first screen segment 21 increases. Similarly, when the second screen segment 22 retracts in a direction away from the first screen segment 21 under the action of an external force, it will cause the first screen segment 21 to extend in a direction closer to the second screen segment 22, and the portion of the first screen segment 21 extending to the rear of the first actuating part 41 will become the second screen segment 22, and the area of ​​the display area will decrease accordingly as the first screen segment 21 decreases.

[0033] The flexible traction component 3 can be a flexible hinge, belt, traction rope, etc. The flexible traction component 3 is laid in the left-right direction. The right half of the flexible traction component 3 forms the second traction section 32, and the right side of the second traction section 32 is connected to the left side of the second screen section 22. The left half of the flexible traction component 3 is folded back around the second actuating part 42 to the rear of the second traction section 32 to form the first traction section 31. The right side of the first traction section 31 is connected and fixed to the main body of the base 1. In this way, the second actuating part 42 will be located on the concave side of the left folded part of the flexible traction component 3.

[0034] Based on the above settings, refer to Figures 6 to 8 When it is necessary to expand the display area to accommodate applications with high visual requirements, such as gaming and movie watching, the adjustment member 4 can be driven to move to the right relative to the base 1, causing the first actuator 41 to abut against and push the right folded part of the flexible screen 2 to the right. With the left side of the first screen segment 21 fixed, this can cause the second screen segment 22, which is rolled up at the rear, to unfold forward, that is, to gradually extend the second screen segment 22 along the direction close to the first screen segment 21. During this process, the part of the second screen segment 22 that continues to unfold forward on the right side will be converted into the first screen segment 21, such as... This causes the area of ​​the second screen segment 22 to gradually decrease and the area of ​​the first screen segment 21 to gradually increase, thus allowing the display area to increase linearly. Simultaneously, the first actuation unit 41 pulls the second traction segment 32 to the right, winding it away from the first traction segment 31, causing the length of the second traction segment 32 to gradually increase and the length of the first traction segment 31 to gradually decrease. With the distance between the first actuation unit 41 and the second actuation unit 42 remaining constant, the decreasing trend of the first traction segment 31 corresponds to the increasing trend of the first screen segment 21. Based on the above operations, the display area can be expanded to 36 inches.

[0035] Similarly, refer to Figure 4 , Figure 5 and Figure 8 When adapting to application scenarios with lower visual requirements, such as daily office work, or when it is necessary to store the display terminal in a small space, the area of ​​the display area needs to be reduced. In this case, the adjustment member 4 can be driven to move to the left relative to the base 1, causing the second actuation part 42 to abut against and push the left folded part of the flexible traction member 3 to the left. With the right side of the first traction section 31 fixed, this can drive the second traction section 32, which is rolled up in front, to unfold backward, that is, drive the second traction section 32 to gradually extend in the direction close to the first traction section 31. During this process, the part of the second traction section 32 that continues to unfold backward on the left side will be converted into the first traction section 31, thus making the length of the first traction section 31 gradually increase. The length of the second traction segment 32 gradually decreases, and the right side of the second traction segment 32 will continuously move to the left under the action of the second actuator 42. This allows the right side of the second traction segment 32 to continuously move the left side of the second screen segment 22 to the left, causing the second screen segment 22 to gradually roll away from the first screen segment 21, which in turn causes the first screen segment 21 to gradually extend towards the second screen segment 22. Thus, the portion of the first screen segment 21 extending to the rear of the first actuator 41 will become the second screen segment 22. This results in the area of ​​the second screen segment 22 gradually increasing and the area of ​​the first screen segment 21 gradually decreasing, thereby allowing the display area to shrink linearly. Based on the above operation, the size of the display area can be reduced to 27 inches.

[0036] Therefore, the display assembly provided in this embodiment, by moving the adjusting member 4 along a preset path, can cause the flexible screen 2 to unfold or retract, achieving stepless adjustment of the display area size. Specifically, when the adjusting member 4 moves forward, its first actuating part 41 causes the second screen segment 22 to gradually extend along the direction close to the first screen segment 21, so that the area of ​​the first screen segment 21, which serves as the display area, gradually increases linearly. This can better adapt to scenarios such as games and movies that have high demands for large-size displays. When the adjusting member 4 moves in the reverse direction, its second actuating part 42, through the flexible traction member 3, causes the second screen segment 22 to gradually retract along the direction away from the first screen segment 21, so that the area of ​​the first screen segment 21, which serves as the display area, gradually decreases linearly. This can better meet the requirements of daily office work or the need for compact size when storing, improving space utilization. The screen retraction method of this solution can replace the traditional simple folding form, reducing creases and mechanical fatigue caused by repeated bending of the same part of the screen, extending the service life of the display device, and better meeting the needs of diverse application scenarios for flexible changes in display screen size.

[0037] In one embodiment, refer to Figures 4 to 8 The display assembly also includes a driving component 5, which is connected to the adjusting component 4. The driving component 5 is used to drive the adjusting component 4 to move forward or backward along a preset path.

[0038] Specifically, the drive assembly 5 may include a motor or other drive components and a matching transmission mechanism. By setting up the drive assembly 5, the manual operation of the adjustment component 4 can be eliminated, thereby improving the convenience of adjustment.

[0039] In one embodiment, refer to Figures 4 to 7 The base 1 is provided with a guide groove 11, which extends along a preset path, and the adjusting member 4 is slidably engaged in the guide groove 11; The drive assembly 5 includes a drive roller 51 and a rotary drive device (not shown in the figure). The drive roller 51 is rotatably connected to the adjusting member 4 and rolls with the groove wall of the guide slide 11. The rotary drive device is connected to the drive roller 51. The rotary drive device is used to drive the drive roller 51 to rotate so that the adjusting member 4 slides along a preset path in the guide slide 11.

[0040] In this embodiment, based on the limiting and guiding effect of the guide groove 11 on the adjusting member 4, the accuracy and stability of the adjusting member 4 during the movement along the preset path can be improved.

[0041] The rotary drive device can be a motor and mounted on the adjusting member 4. When the rotary drive device drives the drive roller 51 to rotate, the drive roller 51 will roll on the groove wall of the guide slide 11. Since the guide slide 11 is in a fixed state, the rolling of the drive roller 51 on the groove wall of the guide slide 11 will drive the adjusting member 4 to move relative to the guide slide 11 in the opposite direction, thereby realizing the driving of the adjusting member 4.

[0042] Based on the driving method of this embodiment, the driving component 5 can be integrated on the adjusting member 4, and the torque output by the rotary driving device can be converted into a driving force on the adjusting member 4 through the rolling cooperation between the driving roller 51 and the groove wall of the guide slide 11, so that the adjusting member 4 can be smoothly driven to move along the preset path in a relatively space-saving manner.

[0043] In one embodiment, refer to Figures 4 to 7 The display assembly also includes a first limiting pulley 6, which is rotatably connected to the adjusting member 4. The first limiting pulley 6 is spaced apart from the driving roller 51, and the first limiting pulley 6 rolls in cooperation with the groove wall of the guide groove 11.

[0044] With the drive roller 51 provided, by adding the first limiting pulley 6, the contact fulcrum between the adjusting member 4 and the groove wall of the guide slide 11 can be increased, so as to more accurately limit the movement path of the adjusting member 4 in the guide slide 11, and prevent the adjusting member 4 from swaying or rotating relative to the guide slide 11 during the movement, thereby improving the smoothness of the movement of the adjusting member 4 and thus improving the smoothness of the flexible screen 2 when unfolding and rewinding.

[0045] In one embodiment, refer to Figures 4 to 8 The display assembly also includes a first drive pulley 7, which is rotatably connected to the first actuation part 41. The first drive pulley 7 is sandwiched between the first screen segment 21 and the second screen segment 22, and the first drive pulley 7 rolls in cooperation with the first screen segment 21 and the second screen segment 22.

[0046] In this embodiment, by setting a first driving roller 51, the sliding friction between the first actuation part 41 and the flexible screen 2 can be converted into rolling friction between the first driving roller 51 and the flexible screen 2. This can reduce the damage to the flexible screen 2 caused by friction and thus extend the service life of the display device.

[0047] In one embodiment, refer to Figures 4 to 8 The display assembly also includes a second drive pulley 8, which is rotatably connected to the second actuation part 42. The second drive pulley 8 is sandwiched between the first traction section 31 and the second traction section 32, and the second drive pulley 8 rolls in cooperation with the first traction section 31 and the second traction section 32.

[0048] In this embodiment, by providing a second drive roller 51, the sliding friction between the second actuation part 42 and the flexible traction member 3 can be converted into rolling friction between the second drive roller 51 and the flexible traction member 3. This reduces the damage to the flexible traction member 3 caused by friction, thereby extending the service life of the display device.

[0049] In one embodiment, refer to Figures 4 to 7 The display assembly also includes a second limiting pulley 9, which is rotatably connected to the adjusting member 4. The second limiting pulley 9 is located between the second traction section 32 and the groove wall of the guide groove 11, and the second limiting pulley 9 and the second traction section 32 are in rolling cooperation.

[0050] By setting the second limiting pulley 9, an obstruction effect is formed between the second traction section 32 and the groove wall of the guide groove 11, and the direction of the second traction section 32 is guided, preventing interference between the second traction section 32 and the groove wall of the guide groove 11, thereby avoiding problems such as abnormal noise and component wear caused by interference. In addition, the second limiting pulley 9 can also be used to create a certain tension on the second traction section 32 to ensure the transmission continuity of the second traction section 32.

[0051] This application also provides a display device; please refer to [link / reference]. Figure 8 and supplementary reference Figures 1 to 3 The display device includes the display screen assembly in any of the above embodiments.

[0052] In this embodiment, the display device may include terminal devices with display functions such as televisions, computers, and e-sports display devices.

[0053] For the specific structure of the display assembly, please refer to the description of the above embodiments. Since the display device in this embodiment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments. That is, by moving the adjusting member 4 along the preset path, the flexible screen 2 can be unfolded or rolled up, realizing stepless adjustment of the display area size. Specifically, when the adjusting member 4 moves forward, its first actuating part 41 drives the second screen segment 22 to gradually extend along the direction close to the first screen segment 21, so that the area of ​​the first screen segment 21, which is the display area, gradually increases in a linear manner. This can better adapt to scenarios such as games and watching movies that have high demands for large-size displays. When the adjusting member 4 moves in the opposite direction, its second actuating part 42 drives the second screen segment 22 to gradually roll up along the direction away from the first screen segment 21 through the flexible traction member 3, so that the area of ​​the first screen segment 21, which is the display area, gradually decreases in a linear manner. This can better meet the requirements of daily office work or the need for compact size when storing, and improve space utilization. This screen rolling method can replace the traditional simple folding method, reducing creases and mechanical fatigue caused by repeated bending of the same part of the screen, extending the service life of the display device, and better meeting the needs of diverse application scenarios for flexible changes in display screen size.

[0054] In one embodiment, refer to Figures 1 to 3 The display device also includes an input signal source (not shown in the figure) and a main control unit (not shown in the figure). The main control unit is electrically connected to the driving circuit (not shown in the figure) of the flexible screen 2 and the input signal source. The main control unit is used to obtain the content information type of the input signal source and generate a matching target resolution and / or target refresh rate. The main control unit is also used to send the target resolution and / or target refresh rate to the driving circuit so that the driving circuit can control the flexible screen 2 to display the image at the target resolution and / or target refresh rate.

[0055] Specifically, the input signal source can use common interfaces such as HDMI, DisplayPort, and USB-C, which can receive video signals from external devices (such as graphics cards, game consoles, and laptops).

[0056] The main control unit can be a common MCU (Microcontroller Unit). The main control unit integrates multiple functional modules, including a processor core, memory, communication interface, etc. It can identify the content information type of the input signal source based on a preset algorithm. The content information type of the input signal source includes games, videos, office, etc. According to the identification result, the main control unit can select the corresponding target resolution and target refresh rate from a preset mapping table and send them to the driving circuit. The driving circuit may include a driving chip packaged in the flexible screen 2. After the driving chip receives the target resolution and target refresh rate sent by the main control unit, it can control the flexible screen 2 to display the corresponding image according to these parameters.

[0057] Based on the above settings, the display device can automatically adjust the resolution and refresh rate according to the input content. Users do not need to manually adjust the graphics card output, which improves the intelligence of the device and can better meet the needs of different application scenarios, further improving the user experience.

[0058] In one embodiment, refer to Figure 9 The display device also includes a counterweight 10, an attitude sensing module (not shown in the figure) and a main control unit (not shown in the figure). The counterweight 10 is movably connected to the base 1, and the main control unit is connected to the counterweight 10 and the attitude sensing module. The attitude sensing module is used to detect the attitude change information of the flexible screen 2 and send it to the main control unit; the main control unit is used to generate corresponding displacement commands based on the attitude change information, so as to control the counterweight 10 to move to the target position through the displacement commands.

[0059] Specifically, the attitude sensing module can use a gyroscope to detect the attitude changes of the flexible screen 2 during the extension and retraction process. The attitude change information of the flexible screen 2 includes real-time data such as speed, acceleration, and angle. The attitude sensing module is used to send this real-time data to the main control unit.

[0060] The main control unit can be a common MCU (Microcontroller Unit). The main control unit integrates multiple functional modules, including a processor core, memory, communication interface, etc. The main control unit can generate corresponding displacement commands based on the received attitude change information according to a preset algorithm. The displacement commands can include the direction of movement, the angle of movement, the distance of movement, etc.

[0061] The counterweight 10 can adopt a slider structure, and a corresponding slide rail structure 12 can be provided on the base 1 so that the counterweight 10 can be slidably fitted in the slide rail structure 12 to ensure the smooth movement of the counterweight 10 on the base 1.

[0062] The counterweight 10 can be driven by a motor, such as a micro DC motor and a corresponding transmission mechanism. When the main control unit calculates the change in the center of gravity of the display device based on the received attitude change information and calculates the required displacement of the counterweight, it can control the motor via a PWM signal to drive the counterweight 10 to move to the target position on the slide rail structure 12. This counterweight 10 counteracts the center of gravity shift of the flexible screen 2 during its extension and retraction, maintaining the stability of the display device and preventing swaying or tipping caused by the shift in the center of gravity. This further enhances the intelligence of the device and the user experience.

[0063] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
