Description

Technical Field

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

[0002] Curved displays, as a novel display technology, have seen widespread application in recent years. These displays not only offer wider viewing angles and a better visual experience but also play a vital role in various settings such as home entertainment and commercial displays. However, with increasing usage frequency, cleaning and maintaining curved displays has become a significant issue. Existing cleaning methods largely rely on manual operation, which is inefficient and prone to damaging the screen. Furthermore, some high-end application environments demand extremely high levels of screen cleanliness, which traditional manual cleaning methods struggle to meet.

[0003] To address these challenges, various automatic cleaning devices for flat panel displays are currently available on the market. For example, some designs employ a fixed scrubbing mechanism that uses a pneumatic or electric motor to drive the scrubbing head in reciprocating motion to remove dust; others feature rotating brush rollers at the edge of the display screen, which are driven by a motor to achieve the cleaning purpose.

[0004] The main problem with existing technologies is that current automatic cleaning devices are generally only suitable for flat screens. For curved screens, traditional cleaning methods cannot effectively clean all areas of the screen surface, resulting in incomplete cleaning and potentially damaging the screen due to mechanical friction. Therefore, there is an urgent need for a more efficient cleaning device that can adapt to curved screens. Summary of the Invention

[0005] The purpose of this application is to overcome the aforementioned technical problems and to provide a curved display screen and electronic device.

[0006] The curved display screen and electronic device provided in this application adopt the following technical solution:

[0007] A curved display screen includes a display screen body, on which a cleaning assembly is provided. The cleaning assembly includes a sliding seat and a brush roller. The sliding seat slides along the curved surface of the display screen body, and the brush roller rotates and is supported on the sliding seat. The surface of the brush roller contacts and rolls with the screen surface of the display screen body.

[0008] By adopting the above technical solution, curved displays can achieve automatic cleaning, effectively removing dust and stains from the screen surface. The sliding base moves along the curved surface of the display body, ensuring that the brush roller can fully cover the entire screen surface for cleaning, improving cleaning efficiency and quality. At the same time, the rolling action design between the brush roller and the screen surface reduces pressure on the screen, avoiding the risk of scratching or damaging the screen.

[0009] Preferably, a driving assembly is provided between the sliding base and the display screen body. The driving assembly includes a driving motor, a first transmission gear, and a transmission rack. The driving motor is coaxially fixed with the first transmission gear, and the transmission rack is fixed to the bottom side wall of the display screen body. The first transmission gear and the transmission rack mesh with each other.

[0010] By adopting the above technical solution, the drive assembly between the sliding base and the display screen body can precisely control the movement path of the brush roller, ensuring uniform coverage during the cleaning process. Specifically, the drive motor transmits power through the meshing of the first transmission gear and the transmission rack, enabling the sliding base to slide smoothly along the curved surface of the display screen body, thereby ensuring that the brush roller can work effectively on the entire screen surface, improving cleaning efficiency and quality.

[0011] Preferably, a guide rod is fixed to the side wall of the display screen body, the guide rod is arranged along the curved surface of the display screen body, and a guide groove is provided on the side wall of the sliding seat, the guide rod slides and engages with the guide groove.

[0012] By adopting the above technical solution, the cooperation between the guide rod and the guide groove enables the sliding seat to move stably along the curved surface of the display screen body, improving the smoothness and positioning accuracy of the cleaning component's operation and effectively avoiding the problem of poor cleaning effect caused by shaking during the sliding process. At the same time, this structural design simplifies the mechanical structure, reduces manufacturing costs, and extends the service life of the equipment.

[0013] Preferably, a rotating plate is provided on the sliding seat, a dual-axis motor is provided on the rotating plate, the brush roller is rotated and supported on the rotating plate, and an electric sprayer is also provided on the rotating plate. The electric sprayer is circumferentially distributed with the brush roller, and the output shaft of the dual-axis motor drives the brush roller and the rotating plate to move in steps.

[0014] By adopting the above technical solution, the rotating plate can be reversed under the control of a dual-axis motor, allowing the electric sprayer and brush roller to move alternately to the front of the display screen. This allows for spraying first, followed by brushing, ensuring a more efficient and thorough cleaning process.

[0015] Preferably, the rotating plate is provided with a first inner ratchet mechanism and a second inner ratchet mechanism. The inner wheel of the first inner ratchet mechanism is coaxially fixed to one of the output shafts of the dual-axis motor. The outer wheel of the first inner ratchet mechanism is coaxially fixed to a second transmission gear. A third transmission gear is fixed on the sliding seat and meshes with the second transmission gear. The inner wheel of the second inner ratchet mechanism is coaxially fixed to the other output shaft of the dual-axis motor. The brush roller is coaxially fixed to the outer wheel of the second inner ratchet mechanism.

[0016] By adopting the above technical solution, the first and second inner ratchet mechanisms have unidirectional transmission control functions. When the output shaft of the dual-axis motor rotates forward, both the inner wheels of the first and second inner ratchet mechanisms rotate. However, due to the unidirectional transmission control characteristics, only the outer wheel of the first inner ratchet mechanism can rotate, thereby driving the second transmission gear to move. The second transmission gear rolls around the third transmission gear, thereby realizing the rotation of the rotating plate and achieving the switching between the electric sprayer and the brush roller. When the brush roller moves to the front side of the display screen, the output shaft of the dual-axis motor rotates in the reverse direction. At this time, the outer wheel of the second inner ratchet mechanism can rotate, thereby driving the brush roller to move and completing the cleaning process.

[0017] Preferably, the sliding seat includes a first seat and a second seat. The first seat is slidably disposed on the display screen body, the drive motor is mounted on the first seat, the second seat is rotatably disposed on the outer side wall of the first seat, and the dual-axis motor is disposed on the second seat.

[0018] By adopting the above technical solution, the second mounting body can rotate to the rear of the display screen body, allowing the entire cleaning assembly to move to the back of the display screen body when not in use. This not only reduces obstruction to the front area of ​​the display screen, ensuring that users can use the display screen normally without being affected by the cleaning device, but also effectively protects the cleaning assembly from damage by the external environment, extending its service life. At the same time, this design improves the overall aesthetics of the equipment and the user experience.

[0019] Preferably, the rotating plate is provided with a receiving groove for receiving waste liquid dripping from the brush roller, the bottom of the rotating plate is provided with a drain hole that communicates with the receiving groove for discharging waste liquid, and the bottom of the rotating plate is provided with a sealing cover for sealing the drain hole.

[0020] By adopting the above technical solution, the receiving groove on the rotating plate can effectively collect the waste liquid generated during the cleaning process, preventing it from splashing everywhere and keeping the environment around the display screen clean. The design of the drain hole connecting to the receiving groove facilitates the centralized discharge of waste liquid, improving cleaning efficiency. The design of the sealing cover plate allows for flexible control of waste liquid discharge, preventing leakage when drainage is not needed and ensuring the stability and reliability of the system.

[0021] Preferably, a mounting plate is provided on the back of the display screen body, and a storage tank is provided on the mounting plate. The sealing cover is rotatably supported on the bottom of the rotating plate. The sealing cover and the rotating plate are connected by a torsion spring. When the second base rotates to the rear of the display screen body, the side wall of the storage tank pushes open the sealing cover so that the leakage hole communicates with the storage tank.

[0022] By adopting the above technical solution, when the second seat rotates to the rear of the display screen body, the side wall of the storage tank can be pushed open relative to the sealing cover, thereby connecting the drain hole with the storage tank and effectively collecting waste liquid. This design not only avoids the pollution problem caused by waste liquid dripping, but also improves the automation and efficiency of the cleaning process. At the same time, the design of connecting the sealing cover and the rotating plate through a torsion spring ensures a rapid response when drainage is required, enhancing the reliability and stability of the system.

[0023] Preferably, the storage tank is detachably connected to the mounting plate.

[0024] By adopting the above technical solution, the storage tank can be detachably connected to the mounting plate, facilitating users to regularly clean or replace the waste liquid inside the tank, thus improving the cleanliness and maintenance convenience of the equipment. At the same time, this design also allows for the easy replacement of storage tanks of different capacities, meeting the needs of various scenarios.

[0025] An electronic device comprising the aforementioned curved display screen.

[0026] By adopting the above technical solution, this electronic device not only possesses a highly efficient cleaning function, effectively removing stains and dust from curved displays and ensuring clear display quality, but also ensures the stability and precision of the cleaning components' operation through the design of drive components and guide rods, avoiding the risk of damage due to positional misalignment. Furthermore, the synergistic effect of the electric sprayer and brush rollers improves cleaning efficiency, while the waste liquid collection system further enhances ease of use and environmental friendliness.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The design of the sliding base and brush roller allows the brush roller to slide precisely along the surface of the curved display screen and roll to clean it, effectively solving the problem that traditional cleaning methods cannot fully cover curved display screens, thus improving cleaning efficiency and quality;

[0029] 2. The drive assembly (drive motor, first transmission gear and transmission rack) ensures that the sliding seat moves stably along the predetermined path, enhancing the consistency and reliability of the cleaning process and avoiding the risk of error and damage caused by manual operation;

[0030] 3. The cooperation between the guide rod and the guide groove further enhances the stability of the sliding seat, ensuring the precise positioning of the brush roller at different positions, thereby achieving effective cleaning of various parts of the curved display screen.

[0036] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0037] This application discloses a curved display screen and an electronic device. (See also...) Figure 1 and Figure 2The curved display screen includes a display screen body 1, which is curved, meaning that the cross-section of the display screen body 1 is arc-shaped. A cleaning component 2 is correspondingly provided on the display screen body 1, which is used to clean the screen surface of the display screen body 1.

[0038] Specifically, the cleaning assembly 2 includes a sliding base 21 and a brush roller 22. The sliding base 21 includes a first base 211 and a second base 212. The first base 211 is disposed below the display body 1 and is circular in shape. The first base 211 slides along the curved surface of the display body 1, that is, it can slide along the length of the display body 1. Meanwhile, the second base 212 is annular in shape and is fitted around the outside of the first base 211. The second base 212 can rotate coaxially with the first base 211, and the brush roller 22 is correspondingly supported on the second base 212. In addition, the brush roller 22 is arranged vertically and is rotatably supported on the sliding base 21. The surface of the brush roller 22 can contact and roll with the screen surface of the display body 1.

[0039] Correspondingly, in order to realize the movement of the first base 211, a drive assembly 3 is provided between the first base 211 and the display screen body 1. The drive assembly 3 includes a drive motor 31, a first transmission gear 32 and a transmission rack 33. The drive motor 31 is fixed on the first base 211, the first transmission gear 32 is coaxially fixed with the output shaft of the drive motor 31, and the transmission rack 33 is fixed to the bottom of the display screen body 1. The transmission rack 33 is arranged along the length direction of the display screen body 1, and the transmission rack 33 meshes with the first transmission gear 32.

[0040] Meanwhile, a guide rod 11 is fixed on the back of the display body 1. The guide rod 11 is arranged along the curved surface of the display body 1. A guide block 2111 is fixed on the upper surface of the first base 211. A guide groove is opened on the side wall of the guide block 2111. The guide rod 11 slides and engages with the guide groove.

[0041] Therefore, when the drive motor 31 is started, the output shaft of the drive motor 31 rotates, driving the first transmission gear 32 to rotate synchronously. Since the first transmission gear 32 meshes with the transmission rack 33, the first seat 211 can move along the length direction of the display body 1 under the guidance of the guide rod 11, and the brush roller 22 can clean the screen surface of the display body 1.

[0042] Reference Figure 1 and Figure 3On the other hand, a support seat 2121 is fixed above the second seat 212. The support seat 2121 rotatably supports the rotating plate 4, which is horizontally arranged and parallel to the second seat 212. A dual-axis motor 41 is fixedly supported on the lower surface of the rotating plate 4. The output shaft of the dual-axis motor 41 is arranged vertically, and the dual-axis motor 41 can control the rotation of the rotating plate 4. Correspondingly, an electric sprayer 42 is also provided on the rotating plate 4. The electric sprayer 42 and the brush roller 22 are circumferentially distributed, that is, with the central axis of the rotating plate 4 as the reference, the electric sprayer 42 and the brush roller 22 are located on both sides of the rotating plate 4 and are circumferentially distributed.

[0043] In this embodiment, the working principle and wide-area spraying design of the electric sprayer 42 combine fluid dynamics and mechanical transmission principles. It achieves a multi-angle, wide-area spraying effect by driving the spraying components to rotate via an electric motor. Specifically, the electric motor inside the electric sprayer 42 drives the spraying components to rotate. The spraying components are equipped with spraying channels. Liquid is sprayed out from these channels, and the spraying effect is achieved by adjusting the rotation angle of the spraying components and the direction of the spraying channels. The spraying channels of the spraying components are at a preset angle to the rotation center, so that when the liquid is sprayed out from the spraying channels, it generates a driving torque in a specific direction on the spraying components, thereby controlling the rotation direction and angle of the spraying components. Furthermore, by changing the rotation speed of the spraying components and the layout of the spraying channels, the coverage and uniformity of the spraying can be further adjusted.

[0044] In other embodiments, the electric sprinkler 42 may also be equipped with an electronic control device, allowing users to adjust the spray angle and spray pattern according to actual needs, achieving more precise spray control. For example, an electronic distributor can switch between various spray patterns to adapt to different spray requirements. This design ensures that the liquid pressure is not lost during spraying, while also enabling automatic rotation of the spray elements, improving the uniformity and coverage of the spray, making it suitable for scenarios requiring large-area, uniform spraying, such as cleaning equipment, agricultural irrigation, and fire protection systems.

[0045] In summary, the electric sprayer 42 drives the spray components to rotate via an electric motor. Combined with the specific design of the spray channel, it achieves a wide-range, multi-angle spraying effect. At the same time, through the electronic control device, the spray angle is controllable, improving the flexibility and applicability of the spraying. Further details will not be elaborated here.

[0046] Therefore, under the control of the dual-axis motor 41, the rotating plate 4 can be reversed, allowing the electric sprayer 42 and the brush roller 22 to move alternately to the front of the display screen body 1. This allows for spraying first during the cleaning process, followed by brushing by the brush roller 22, ensuring a more efficient and thorough cleaning process.

[0047] Specifically, the rotating plate 4 is provided with a first inner ratchet mechanism 5 and a second inner ratchet mechanism 6. The inner wheel of the first inner ratchet mechanism 5 is coaxially fixed with the vertically downward output shaft of the dual-axis motor 41, and the outer wheel of the first inner ratchet mechanism 5 is rotated and supported by the underside of the rotating plate 4.

[0048] Meanwhile, the outer wheel of the first inner ratchet mechanism 5 is coaxially fixed with the second transmission gear 7, and the sliding seat 21 is fixed with the third transmission gear 8. The third transmission gear 8 is coaxially arranged with the rotating plate 4, and the third transmission gear 8 meshes with the second transmission gear 7.

[0049] In addition, the other output shaft of the dual-axis motor 41 is vertically upward and passes through the upper surface of the rotating plate 4, and the inner wheel of the second inner ratchet mechanism 6 is coaxially fixed with the other output shaft of the dual-axis motor 41. The outer wheel of the second inner ratchet mechanism 6 is rotated and supported above the rotating plate 4, and the brush roller 22 is coaxially fixed with the outer wheel of the second inner ratchet mechanism 6.

[0050] When the dual-axis motor 41 starts, its two output shafts drive the inner wheels of the first inner ratchet mechanism 5 and the second inner ratchet mechanism 6 to rotate, respectively. The outer wheel of the first inner ratchet mechanism 5 transmits power to the sliding seat 21 through the meshing of the second transmission gear 7 and the third transmission gear 8, thereby realizing the positioning and spraying action of the electric sprayer 42. At the same time, the outer wheel of the second inner ratchet mechanism 6 directly drives the brush roller 22 to rotate, performing washing and cleaning.

[0051] During the cleaning process, the dual-axis motor 41 controls the reversal of the rotating plate 4, allowing the electric sprayer 42 and the brush roller 22 to move alternately to the front side of the display screen body 1. This design ensures the high efficiency of the cleaning process, with the electric sprayer 42 first pre-treating the screen, followed by deep cleaning by the brush roller 22, thus achieving a thorough cleaning effect.

[0052] It should be noted that the working principle of the internal ratchet mechanism lies in its unidirectional transmission characteristic. Even when the motor stops or rotates in the reverse direction, the outer wheel can maintain its rotation, ensuring the continuity and reliability of the cleaning action. This design fully utilizes the characteristics of the internal ratchet mechanism, combined with the bidirectional rotation capability of the dual-axis motor 41, to achieve highly efficient automated operation of the cleaning equipment, reduce manual intervention, and improve cleaning efficiency and effectiveness.

[0053] In summary, this automated cleaning equipment achieves automation and high efficiency in cleaning displays through a dual-axis motor 41, an internal ratchet mechanism, and a precise transmission system.

[0054] Reference Figure 1 and Figure 4On the other hand, since the second seat 212 is rotatably mounted on the outer wall of the first seat 211, and the dual-axis motor 41 is mounted on the second seat 212, the second seat 212 can rotate towards the rear of the display screen body 1, allowing the entire cleaning assembly 2 to move to the back of the display screen body 1 when not in use. This not only reduces obstruction to the front area of ​​the display screen, ensuring that users can use the display screen normally without being affected by the cleaning device, but also effectively protects the cleaning assembly 2 from damage by the external environment, extending its service life. At the same time, this design improves the overall aesthetics of the equipment and the user experience.

[0055] Furthermore, the rotating plate 4 is provided with a receiving groove 43 (in conjunction with...) Figure 3 The receiving groove 43 is used to receive the waste liquid of the brush roller 22. The bottom of the rotating plate 4 is provided with a leakage hole, which is connected to the receiving groove 43 for discharging the waste liquid. The bottom of the rotating plate 4 is provided with a sealing cover plate 44, which is used to seal the leakage hole.

[0056] Therefore, the receiving groove 43 on the rotating plate 4 can effectively collect the waste liquid generated during the cleaning process, preventing the waste liquid from splashing everywhere and keeping the environment around the display screen clean. The design of the drain hole communicating with the receiving groove 43 facilitates the centralized discharge of waste liquid, improving cleaning efficiency. The design of the sealing cover plate 44 allows for flexible control of waste liquid discharge, avoiding leakage when drainage is not needed, and ensuring the stability and reliability of the system.

[0057] Furthermore, a mounting plate 12 is provided on the back of the display screen body 1, and a storage tank 9 is provided on the mounting plate 12. A sealing cover 44 is rotatably supported on the bottom of a rotating plate 4. The sealing cover 44 and the rotating plate 4 are connected by a torsion spring. When the second seat 212 rotates to the rear of the display screen body 1, the side wall of the storage tank 9 pushes open the sealing cover 44 so that the leakage hole communicates with the storage tank 9.

[0058] When the second seat 212 rotates to the rear of the display screen body 1, the side wall of the storage tank 9 can push open the sealing cover 44, thereby connecting the drain hole with the storage tank 9 and effectively collecting waste liquid. This design not only avoids the pollution problem caused by waste liquid dripping, but also improves the automation and efficiency of the cleaning process. At the same time, the design of the sealing cover 44 and the rotating plate 4 connected by a torsion spring ensures a rapid response when drainage is required, enhancing the reliability and stability of the system.

[0059] It should be noted that the sealing cover 44 is designed to be connected to the rotating plate 4, and the connection between the two is achieved through a torsion spring. As an elastic element, the torsion spring can store and release energy. When the second seat 212 rotates to the rear of the display screen body 1, and the side wall of the storage tank 9 contacts the sealing cover 44, it overcomes the spring force, causing the sealing cover 44 to shift and thus opening the channel between the leak and the storage tank 9. This process is automated. When the pressure on the side wall is removed, the torsion spring quickly returns to its original shape, driving the sealing cover 44 back to its initial position, resealing the leak, and ensuring the system's sealing performance when not in use.

[0060] Furthermore, when the second seat 212 rotates, there is sufficient space between the structural components on the second seat 212 and the display screen body 1.

[0061] On the other hand, this application also discloses an electronic device including the aforementioned curved display screen. This electronic device not only possesses a highly efficient cleaning function, effectively removing stains and dust from the curved display screen and ensuring the clarity of the display effect; simultaneously, by setting the drive component 3 and guide rod 11, it ensures the stability and accuracy of the cleaning component 2's operation, avoiding the risk of damage due to positional misalignment. Furthermore, the synergistic effect of the electric sprayer 42 and the brush roller 22 improves cleaning efficiency, while the design of the waste liquid collection system further enhances ease of use and environmental performance.

[0062] The implementation principle of the curved display screen and electronic device in this application embodiment is as follows: The curved display screen can realize an automatic cleaning function, effectively removing dust and stains from the screen surface. The sliding base 21 moves along the curved surface of the display screen body 1, ensuring that the brush roller 22 can fully cover the entire screen surface for cleaning, improving cleaning efficiency and quality. At the same time, the rolling cooperation design between the brush roller 22 and the screen surface reduces the pressure on the screen, avoiding the risk of scratching or damaging the screen.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
