Description

Technical Field

[0001] The present application relates to the field of electronic display devices, and in particular to a curved display screen and electronic equipment. Background Art

[0002] As a new display technology, curved display screens have been widely used in recent years. This type of display not only has a wider viewing angle and better visual experience, but also plays an important role in various occasions such as home entertainment and commercial display. However, with the increase in frequency of use, the cleaning and maintenance of curved display screens has become an important issue. Existing cleaning methods mostly rely on manual operation, which is inefficient and easy to cause screen damage. In addition, some high-end application environments have extremely high requirements for the cleanliness of the screen, and traditional manual cleaning methods are difficult to meet these requirements.

[0003] In order to meet the above challenges, there are currently a variety of automatic cleaning devices for flat-panel displays on the market. For example, some designs use a fixed scrubbing mechanism that uses a pneumatic or electric motor to drive the scrubbing head to reciprocate to remove dust; others set a rotating brush roller at the edge of the display screen and use a motor to drive the brush roller to rotate to achieve the purpose of cleaning.

[0004] The main problem in the prior art is that the existing automatic cleaning devices are usually only applicable to flat display screens. For the special shape of curved display screens, the traditional cleaning method cannot effectively clean all areas of the screen surface, resulting in incomplete cleaning and even possible damage to the screen due to mechanical friction. Therefore, there is an urgent need for an efficient cleaning device that can adapt to curved display screens. Summary of the invention

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

[0006] The curved display screen and electronic device provided in this application adopt the following technical solutions: A curved display screen includes a display screen body, on which a cleaning component is arranged, the cleaning component includes a sliding seat and a brush roller, the sliding seat slides along the curved surface of the display screen body, the brush roller is rotatably carried on the sliding seat, and the surface of the brush roller contacts and rolls with the screen surface of the display screen body.

[0007] By adopting the above technical solution, the curved display screen can realize the automatic cleaning function and effectively remove dust and stains on the screen surface. The sliding seat moves along the curved surface of the display screen body, ensuring that the brush roller can fully cover the entire screen surface for cleaning, thereby improving the cleaning efficiency and quality. At the same time, the rolling matching design of the brush roller and the screen surface reduces the pressure on the screen and avoids the risk of scratching or damaging the screen.

[0008] Preferably, a driving assembly is arranged between the sliding seat and the display screen body, and 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 are meshed with each other.

[0009] By adopting the above technical solution, the driving assembly between the sliding seat and the display screen body can accurately control the moving path of the brush roller to ensure uniform coverage during the cleaning process. Specifically, the driving motor transmits power through the meshing of the first transmission gear and the transmission rack, so that the sliding seat slides smoothly along the curved surface of the display screen body, thereby ensuring that the brush roller can work effectively on the entire screen surface and improving the cleaning efficiency and quality.

[0010] 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, a guide groove is formed on the side wall of the sliding seat, and the guide rod is slidably matched with the guide groove.

[0011] By adopting the above technical solution, the cooperation between the guide rod and the guide groove enables the sliding seat to stably move along the curved surface of the display screen body, improving the stability and positioning accuracy of the cleaning component, 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.

[0012] Preferably, a rotating plate is provided on the sliding seat, a dual-axis motor is provided on the rotating plate, the brush roller is rotatably supported on the rotating plate, an electric sprayer is also provided on the rotating plate, the electric sprayer and the brush roller are circumferentially distributed, and the output shaft of the dual-axis motor drives the brush roller and the rotating plate to move in steps.

[0013] By adopting the above technical solution, under the control of the dual-axis motor, the reversing action of the rotating plate can be realized, so that the electric sprayer and the brush roller can alternately move to the front side of the screen of the display screen body. In this way, during the cleaning process, the spraying operation can be performed first, and then the brush roller can be used for scrubbing, ensuring that the cleaning process is more efficient and thorough.

[0014] Preferably, a first inner ratchet mechanism and a second inner ratchet mechanism are provided on the rotating plate, the inner wheel of the first inner ratchet mechanism is coaxially fixed with one of the output shafts of the dual-axis motor, the outer wheel of the first inner ratchet mechanism is coaxially fixed with a second transmission gear, a third transmission gear is fixed on the sliding seat, the third transmission gear is meshed with the second transmission gear, the inner wheel of the second inner ratchet mechanism is coaxially fixed with the other output shaft of the dual-axis motor, and the brush roller is coaxially fixed with the outer wheel of the second inner ratchet mechanism.

[0015] By adopting the above technical solution, the first inner ratchet mechanism and the second inner ratchet mechanism have a one-way transmission control function. When the output shaft of the dual-axis motor rotates forward, the inner wheel of the first inner ratchet mechanism and the inner wheel of the second inner ratchet mechanism both rotate, but due to the one-way transmission control characteristics, only the outer wheel of the first inner ratchet mechanism can rotate, thereby driving the second transmission gear to move, and the second transmission gear rolls around the third transmission gear, thereby realizing the rotation of the rotating plate and the switching between the electric sprayer and the brush roller. When the brush roller moves to the front side of the screen of the display screen body, the output shaft of the dual-axis motor rotates in the opposite direction. At this time, the outer wheel of the second inner ratchet mechanism can rotate, thereby driving the brush roller to move and complete the cleaning process.

[0016] Preferably, the sliding seat includes a first seat body and a second seat body, the first seat body is slidably set on the display screen body, the driving motor is installed on the first seat body, the second seat body is rotatably set on the outer wall of the first seat body, and the dual-axis motor is set on the second seat body.

[0017] By adopting the above technical solution, the second seat can be rotated toward the rear side of the display screen body, so that the entire cleaning assembly can be moved to the back side of the display screen body when not in use. This not only reduces the obstruction of the front area of ​​the display screen, ensuring that the user 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 device and user experience.

[0018] Preferably, a receiving groove is provided on the rotating plate, and the receiving groove is used to receive the waste liquid dripping from the brush roller. A leakage hole is provided at the bottom of the rotating plate, and the leakage hole is connected to the receiving groove for discharging the waste liquid. A sealing cover plate is provided at the bottom of the rotating plate, and the sealing cover plate is used to seal the leakage hole.

[0019] By adopting the above technical solution, the receiving groove on the rotating plate can effectively collect the waste liquid generated during the cleaning process, prevent the waste liquid from splashing everywhere, and keep the environment around the display screen clean. The leakage hole and the receiving groove are connected to facilitate the centralized discharge of waste liquid and improve the cleaning efficiency. The design of the sealing cover can flexibly control the discharge of waste liquid, avoid leakage when drainage is not required, and ensure the stability and reliability of the system.

[0020] 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 plate is rotatably supported on the bottom of the rotating plate, and the sealing cover plate is connected to the rotating plate via a torsion spring. When the second seat body rotates to the rear of the display screen body, the side wall of the storage tank relatively pushes open the sealing cover plate to connect the leakage hole with the storage tank.

[0021] By adopting the above technical solution, when the second seat body rotates to the rear of the display screen body, the side wall of the storage tank can relatively push open the sealing cover plate, so that the leak hole is connected to the storage tank and the waste liquid is effectively collected. This design not only avoids the pollution problem caused by the dripping of waste liquid, but also improves the automation and efficiency of the cleaning process. At the same time, the design of connecting the sealing cover plate and the rotating plate through a torsion spring ensures a quick response when drainage is required, thereby enhancing the reliability and stability of the system.

[0022] Preferably, the storage tank is detachably connected to the mounting plate.

[0023] By adopting the above technical solution, the storage tank can be detachably connected to the mounting plate, which is convenient for users to regularly clean or replace the waste liquid in the storage tank, improving the cleanliness and maintenance convenience of the equipment. At the same time, this design also facilitates the replacement of storage tanks of different capacities to meet the needs of different scenarios.

[0024] An electronic device comprises the above-mentioned curved display screen.

[0025] By adopting the above technical solution, the electronic device not only has an efficient cleaning function, but can also effectively remove stains and dust on the curved display screen to ensure the clarity of the display effect; at the same time, by setting up the drive component and the guide rod, the stability and accuracy of the cleaning component operation are ensured, avoiding the risk of damage caused by position offset. In addition, the synergy between the electric sprayer and the brush roller improves the cleaning efficiency, and the design of the waste liquid collection system further improves the convenience of use and environmental protection performance.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0033] The embodiments of the present application disclose a curved display screen and an electronic device. Figure 1 and Figure 2 The curved display screen includes a display screen body 1, which is arranged in a curved surface, that is, the cross section of the display screen body 1 is arranged in an arc shape. A cleaning component 2 is correspondingly arranged on the display screen body 1. Correspondingly, the cleaning component 2 is used to clean the screen surface of the display screen body 1.

[0034] Specifically, the cleaning assembly 2 includes a sliding seat 21 and a brush roller 22. The sliding seat 21 includes a first seat body 211 and a second seat body 212. The first seat body 211 is arranged below the display screen body 1. The first seat body 211 is arranged in a circular shape. The first seat body 211 slides along the curved surface of the display screen body 1, that is, the first seat body 211 can slide along the length direction of the display screen body 1. At the same time, the second seat body 212 is arranged in a circular ring shape. The second seat body 212 is sleeved on the outside of the first seat body 211. The second seat body 212 can rotate coaxially with the first seat body 211, and the brush roller 22 is correspondingly carried on the second seat body 212. In addition, the brush roller 22 is arranged in the vertical direction, and the brush roller 22 is rotatably carried on the sliding seat 21. The surface of the brush roller 22 can contact and roll with the screen surface of the display screen body 1.

[0035] Correspondingly, in order to realize the movement of the first seat body 211, a driving assembly 3 is arranged between the first seat body 211 and the display screen body 1. The driving assembly 3 includes a driving motor 31, a first transmission gear 32 and a transmission rack 33. The driving motor 31 is fixed on the first seat body 211, the first transmission gear 32 is coaxially fixed with the output shaft of the driving motor 31, 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 and the first transmission gear 32 are meshed with each other.

[0036] At the same time, a guide rod 11 is fixed to the back of the display screen body 1, and the guide rod 11 is arranged along the curved surface of the display screen body 1. A guide block 2111 is fixed to the upper surface of the first seat body 211, and a guide groove is provided on the side wall of the guide block 2111, and the guide rod 11 slides in cooperation with the guide groove.

[0037] 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 and the transmission rack 33 are meshed with each other, the first seat body 211 can move along the length direction of the display screen body 1 under the guidance of the guide rod 11, and the brush roller 22 can clean the screen surface of the display screen body 1.

[0038] Reference Figure 1 and Figure 3On the other hand, a bearing seat 2121 is fixed above the second seat body 212, and the bearing seat 2121 rotatably carries the rotating plate 4, which is arranged horizontally, and the rotating plate 4 and the second seat body 212 are parallel to each other. A double-axis motor 41 is fixedly carried on the lower surface of the rotating plate 4, and the output shaft of the double-axis motor 41 is arranged in the vertical direction, and the double-axis motor 41 can control the rotation of the rotating plate 4. Correspondingly, an electric sprayer 42 is also arranged on the rotating plate 4, and the electric sprayer 42 and the brush roller 22 are arranged circumferentially, that is, with the central axis of the rotating plate 4 as a reference, the electric sprayer 42 and the brush roller 22 are respectively located on both sides of the rotating plate 4 and are circumferentially distributed.

[0039] In this embodiment, the working principle and wide-range spray design of the electric sprayer 42 combine the principles of fluid dynamics and mechanical transmission, and the spray assembly is driven to rotate by an electric motor to achieve a multi-angle and wide-range spray effect. Specifically, the motor inside the electric sprayer 42 drives the spray part to rotate, and a spray channel is provided on the spray part. When the liquid is sprayed from these channels, it is achieved by adjusting the rotation angle of the spray part and the direction of the spray channel. The spray channel of the spray part is at a preset angle to the rotation center, so that when the liquid is sprayed from the spray channel, it generates a driving torque in a specific direction on the spray part, thereby controlling the rotation direction and angle of the spray part. In addition, by changing the rotation speed of the spray part and the layout of the spray channel, the coverage and uniformity of the spray can be further adjusted.

[0040] In addition, in other embodiments, the electric sprinkler 42 may also be equipped with an electronic control device, allowing the user to adjust the spray angle and spray mode according to actual needs to achieve more accurate spray control. For example, through an electronic diverter, it is possible to switch between multiple spray patterns to adapt to different spray needs. This design ensures that the pressure of the liquid is not lost during the spraying process, while realizing the automatic rotation of the spraying part, improving the uniformity and coverage of the spray, and is suitable for scenes that require large-scale, uniform spraying, such as cleaning equipment, agricultural irrigation, fire protection systems, etc.

[0041] In summary, the electric sprinkler 42 drives the spray element to rotate through an electric motor, and combined with the specific design of the spray channel, achieves a large-range, multi-angle spray effect. At the same time, through the electronic control device, the controllability of the spray angle is achieved, which improves the flexibility and applicability of the spray. No further details will be given here.

[0042] Therefore, under the control of the dual-axis motor 41, the reversing action of the rotating plate 4 can be realized, so that the electric sprayer 42 and the brush roller 22 can alternately move to the front side of the screen of the display screen body 1. In this way, the spraying operation can be performed first during the cleaning process, and then the brush roller 22 can be used for brushing, ensuring that the cleaning process is more efficient and thorough.

[0043] Specifically, a first inner ratchet mechanism 5 and a second inner ratchet mechanism 6 are provided on the rotating plate 4, wherein 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 rotatably supported below the rotating plate 4.

[0044] At the same time, the outer wheel of the first inner ratchet mechanism 5 is coaxially fixed with the second transmission gear 7 , 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 is meshed with the second transmission gear 7 .

[0045] 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 rotatably carried above the rotating plate 4, and the brush roller 22 is coaxially fixed with the outer wheel of the second inner ratchet mechanism 6.

[0046] When the dual-axis motor 41 is started, its two output shafts respectively drive the inner wheels of the first inner ratchet mechanism 5 and the second inner ratchet mechanism 6 to rotate. 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 for scrubbing and cleaning.

[0047] During the cleaning process, the dual-axis motor 41 controls the reversal of the rotating plate 4, so that the electric sprayer 42 and the brush roller 22 can alternately move to the front side of the screen of the display screen body 1. This design ensures the high efficiency of the cleaning process, and the electric sprayer 42 first pre-treats the screen, and then the brush roller 22 performs deep cleaning, thereby achieving a thorough cleaning effect.

[0048] It should be noted that the working principle of the inner ratchet mechanism lies in its one-way transmission characteristics, which can maintain the rotation state of the outer wheel even when the motor stops or rotates in the reverse direction, ensuring the continuity and reliability of the cleaning action. This design makes full use of the characteristics of the inner ratchet mechanism, combined with the bidirectional rotation capability of the dual-axis motor 41, to achieve efficient automatic operation of the cleaning equipment, reduce manual intervention, and improve cleaning efficiency and effect.

[0049] In summary, the automatic cleaning device achieves automation and high efficiency in display screen cleaning through the dual-axis motor 41, the internal ratchet mechanism and the precise transmission system.

[0050] Reference Figure 1 and Figure 4On the other hand, since the second seat body 212 is rotatably arranged on the outer side wall of the first seat body 211 and the dual-axis motor 41 is arranged on the second seat body 212, the second seat body 212 can rotate toward the rear side of the display screen body 1, so that the entire cleaning assembly 2 can be moved to the back side of the display screen body 1 when not in use. This not only reduces the obstruction of the front area of ​​the display screen, ensuring that the user 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 and user experience of the device.

[0051] Furthermore, the rotating plate 4 is provided with a receiving groove 43 (combined with Figure 3 ), the receiving groove 43 is used to receive the waste liquid of the brush roller 22, a leakage hole is provided at the bottom of the rotating plate 4, the leakage hole is connected to the receiving groove 43 for discharging the waste liquid, and a sealing cover plate 44 is provided at the bottom of the rotating plate 4, and the sealing cover plate 44 is used to block the leakage hole.

[0052] Therefore, the receiving groove 43 on the rotating plate 4 can effectively collect the waste liquid generated during the cleaning process, prevent the waste liquid from splashing everywhere, and keep the environment around the display screen clean. The leakage hole is connected to the receiving groove 43, which is convenient for centralized discharge of waste liquid and improves cleaning efficiency. The design of the sealing cover plate 44 can flexibly control the discharge of waste liquid, avoid leakage when drainage is not required, and ensure the stability and reliability of the system.

[0053] 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 plate 44 is rotatably supported on the bottom of the rotating plate 4, and the sealing cover plate 44 is connected to the rotating plate 4 through a torsion spring. When the second seat body 212 rotates to the rear of the display screen body 1, the side wall of the storage tank 9 relatively pushes open the sealing cover plate 44 to connect the leakage hole with the storage tank 9.

[0054] When the second seat 212 rotates to the rear of the display screen body 1, the side wall of the storage tank 9 can relatively push open the sealing cover plate 44, so that the leak hole is connected to the storage tank 9, and the waste liquid is effectively collected. This design not only avoids the pollution problem caused by the dripping of waste liquid, but also improves the automation and efficiency of the cleaning process. At the same time, the design of connecting the sealing cover plate 44 and the rotating plate 4 through a torsion spring ensures a quick response when drainage is required, and enhances the reliability and stability of the system.

[0055] It should be noted that the sealing cover plate 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 body 212 rotates to the rear of the display screen body 1 and the side wall of the storage tank 9 contacts the sealing cover plate 44, the elastic force of the torsion spring will be overcome, causing the sealing cover plate 44 to move, thereby opening the channel between the leak hole and the storage tank 9. This process is automated. When the pressure on the side wall is removed, the torsion spring will quickly return to its original state, driving the sealing cover plate 44 back to the initial position, re-closing the leak hole, and ensuring the sealing of the system when not in use.

[0056] In addition, when the second base body 212 rotates, there is enough space between the structural components on the second base body 212 and the display screen body 1 .

[0057] On the other hand, the embodiment of the present application also discloses an electronic device, including the above-mentioned curved display screen. The electronic device not only has an efficient cleaning function, but can also effectively remove stains and dust on the curved display screen to ensure the clarity of the display effect; at the same time, by setting the drive component 3 and the guide rod 11, the stability and accuracy of the operation of the cleaning component 2 are ensured, and the risk of damage caused by position offset is avoided. In addition, the synergistic effect of the electric sprayer 42 and the brush roller 22 improves the cleaning efficiency, and the design of the waste liquid collection system further improves the convenience of use and environmental protection performance.

[0058] The implementation principle of the curved display screen and electronic device of the embodiment of the present application is as follows: the curved display screen can realize the automatic cleaning function and effectively remove dust and stains on the screen surface. The sliding seat 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, thereby improving the cleaning efficiency and quality. At the same time, the rolling matching design of the brush roller 22 and the screen surface reduces the pressure on the screen and avoids the risk of scratching or damaging the screen.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
