Description

Technical Field

[0001] The present invention relates to the technical field of module structures, and in particular to an assembly structure of a curved liquid crystal display module. Background Art

[0002] With the continuous development of science and technology, curved display liquid crystal devices with curved display screens and backlight sources have gradually appeared on the market. Because the retina of the human eye is curved, when users watch the flat display screen of a flat display device, the brain needs to perform a "flat-curved-flat" conversion. The curved display module has a curved display screen, so it can intuitively map the picture to the brain at the same angle. This does not require the brain to convert the picture, which reduces the pressure on the brain. In addition, due to the curved shape of the display screen of the curved display device, the curved display module can achieve better viewing angles on the left and right sides, giving users a more natural and comfortable visual experience.

[0003] In the prior art, when making a curved display module, generally all components of the backlight source are made into a curved shape, and then assembled into a curved backlight source, and finally the originally flat display screen is bent and installed on the curved backlight source. However, when such a method is used to make a curved display device, after all components of the backlight source are made into a curved shape, the curvature of the backlight source is fixed, which results in the curvature of the manufactured curved display module being fixed. The curvature of the curved screen (i.e., the degree of curvature of the display screen) will have different effects on different usage scenarios (such as playing games, watching movies, and watching short videos). For gaming scenarios, especially when the immersive experience is the focus, the choice of curved screens usually tends to be stronger in curvature, in order to enhance the visual surround and immersive experience. The movie watching experience pays more attention to the clarity and viewing comfort of the picture. Therefore, the appropriate curvature usually does not need to be too strong. Too strong curvature will cause image distortion, especially when watching on a large screen or at close range. Therefore, a device that can meet the user's personalized requirements for the curvature of the curved display device is needed.

[0004] In view of the above problems, the prior art provides some solutions. For example, the invention patent with patent application number CN201410705445.X provides a curved liquid crystal display device, in which the front shell is installed on the periphery of the liquid crystal panel and the backlight module, and the curved adjustment component includes a curved support plate with a certain curvature and several adjustment parts. The adjustment part includes a driving part, a nut fixedly connected to the driving part, and a screw threadedly connected to the nut. The nut is fixed on the curved support plate, the edge of the backlight module is limited on the curved support plate, the free end of the screw is fixedly connected to the backlight module, the driving part drives the nut to rotate, and the nut drives the screw to move relative to the curved support plate, thereby driving the backlight module to change the curvature. However, since the adjustment part does not have a segmented adjustment function and the user is not clear about the specific adjustment value, the user cannot enjoy the effect of changing the curvature between games and movies. Summary of the invention

[0005] The purpose of the present invention is to provide a curved liquid crystal display module assembly structure to solve the problem that the curvature of the existing curved liquid crystal display screen cannot be adjusted to a suitable curvature according to different usage scenarios, so that the curved liquid crystal display screen cannot provide the best curvature display effect in different usage scenarios; and when the above problem occurs in the curved liquid crystal display module assembly structure, the curved liquid crystal display screen cannot meet the user's personalized requirements for the curvature of the curved display device, while solving the shortcomings of the existing technical solutions.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A curved liquid crystal display module assembly structure, comprising a liquid crystal module and a frame, wherein the liquid crystal module is installed in the frame, wherein the frame is a flexible plastic made of polycarbonate, and specifically, an adjustment component and a flexible back plate are arranged on the rear end surface of the liquid crystal module, wherein the adjustment component comprises a curved arm with an arc and an adjustment rack, wherein a mirror-symmetrical rotating tooth is arranged in the middle of the curved arm, wherein the adjustment rack is meshed between two rotating teeth, wherein mounting grooves are arranged on the left and right sides of the flexible back plate, wherein two ends of the curved arm away from the rotating tooth are connected to the mounting grooves, wherein the adjustment rack is connected to the center of the flexible back plate, and wherein the curved arm is connected to the mounting grooves. A handle is slidably installed in the connection of the groove, and an arc surface component is provided in the curved arm, and the arc surface component includes a telescopic frame and a flexible slider. The handle is fixedly connected to the flexible slider, and the telescopic frame is slidably installed in the curved arm. The flexible slider abuts against the flexible back plate. The adjustment component cooperates with the handle to stretch outward from the curved arm so that the flexible slider stretches the telescopic frame while moving away from the flexible back plate, so that the liquid crystal module changes from a convex arc surface to a flat surface. The adjustment component cooperates with the handle to squeeze toward the center line of the flexible back plate, so that the liquid crystal module changes from a flat surface to a curved surface, thereby achieving the purpose of changing the curvature of the liquid crystal module.

[0008] It is easy to understand that when the user is working or playing a competitive game that requires concentration, the LCD module can apply a pulling force to the handle and a pushing force toward the back of the LCD module to make the curved arm rotate and extend, thereby stretching and tensioning the LCD module so that the LCD module is in a plane; and when the user wants to watch videos or check some fragmented messages, by squeezing the handle into the sliding groove, the flexible slider compresses the telescopic frame while approaching the flexible back plate, so that the LCD module has a margin on both sides due to the shortening of the curved arm, thereby changing the curvature of the LCD module from a plane to a convex arc surface; and when the user wants to improve the immersion in watching movies and some racing games, by squeezing the handle toward the center line of the flexible back plate, the angle of the curved arm is reduced, so that the LCD module changes from a plane to a curved surface with a curvature suitable for long-term observation by the human eye, and the curvature changes on both sides of the center line of the LCD module are ensured to remain consistent through the cooperation of the curved arm and the adjustment rack, thereby achieving the purpose of simply and accurately changing the curvature of the LCD module.

[0009] Preferably, the adjustment assembly also includes a limit block, a sliding groove and a rotating shaft, the sliding groove is opened in the crank arm, the limit block is arranged on the adjustment rack, the rotating gear is located between the limit blocks, the limit block is parallel to the outer edge surface of the crank arm and the rotating shaft is coaxially connected with the rotating gear, a gasket is provided between the rotating shaft and the crank arm, a screw that cooperates with the rotating shaft thread is also provided on the gasket, the handle is slidably connected to the sliding groove, an abutment portion is provided in the sliding groove, and the abutment portion abuts against the handle.

[0010] It is easy to understand that when the liquid crystal module is in a planar state, by setting mirror-symmetrical rotating teeth on the crank arm and adjusting the rack to mesh with the rotating teeth, when the user squeezes the handle toward the center line of the flexible back panel, the steering angle of the crank arm is the same because the adjusting rack is meshed with the rotating teeth on both sides, so that the curvatures on both sides of the center line of the flexible back panel are exactly the same. The adjusting rack, the crank arm and the rear end face of the flexible back panel are connected at three points, which ensures the curvature of both sides of the flexible back panel without causing the curved surface direction of the flexible back panel to change due to the squeezing of the crank arm. At the same time, by setting a limit block on the adjusting rack, the limit block and the The abutment of the rotating teeth limits the steering angle of the crank arm, thereby ensuring that the user can adjust the curvature to the desired curvature in one step, and by setting a gasket between the rotating shaft and the crank arm and tightening the screws, the damping between the crank arm and the rotating shaft is adjusted, and the curvature of the LCD module is accurately changed through the coordination of the mechanical structure. The structure is simple and easy to maintain, avoiding the problem of possible damage to electronic devices such as servo motors during use. While ensuring that the curvature of the LCD module can be adjusted by manpower, it also ensures that external forces cannot affect the curvature of the LCD module, thereby realizing the switching of the curvature of the curved surface when the LCD module is flat.

[0011] Preferably, the arc surface assembly also includes a gear rotatably installed in the crank arm, the flexible slider slides through the sliding groove, the telescopic frame and the flexible slider are both provided with a rack portion, the rack portion is meshed with the gear, and the flexible slider is also provided with a limit spring, the upper and lower ends of the limit spring are respectively abutted against the flexible slider and the outer edge surface of the crank arm.

[0012] It is easy to understand that when the liquid crystal module is in a planar state, the handle is pressed into the sliding groove, and the flexible slider moves toward the flexible back panel. Due to the setting of the gear, the rack portion on the flexible slider is meshed with the gear, thereby ensuring the smooth movement of the flexible slider. The limit spring on the flexible back panel ensures that the moving direction of the flexible slider when extending out of the sliding groove is 90° with the flexible back panel due to the hardness and elasticity of the spring. The rack portion on the telescopic frame is meshed with the gear. In the above process, the telescopic frame moves into the sliding groove due to the rotation of the gear, so that the length of the curved arm is shortened until the flexible slider abuts against the flexible back panel. At this time, the liquid crystal module has convex arc surfaces on the left and right sides due to the influence of the state of the flexible slider and the length of the curved arm and the flexibility of the flexible back panel, thereby realizing the switching of the curvature of the convex arc surface when the liquid crystal module is in a plane.

[0013] Preferably, shading modules are arranged in an array on the frame of the liquid crystal module, and the shading modules are in an "L" shape. A guide rail is provided at the position of the flexible back panel corresponding to the shading module, and the shading module is slidably connected to the guide rail. A return spring is provided in the guide rail, and the upper and lower ends of the return spring are respectively connected to the guide rail and the tail end of the shading module. A bevel gear group is also provided on the curved arm, and an optical axis is fixedly connected to the bevel gear group. The optical axis is rotatably connected to cams at both ends away from the adjusting rack, and the elliptical top of the cam is connected to the tail end of the shading module by a plastic rope.

[0014] It is easy to understand that, because the frame needs to ensure its hardness and lightness while deforming with the liquid crystal module, it is inevitable that the curvature of the frame during deformation is completely consistent with that of the liquid crystal module, which will cause a gap between the frame and the liquid crystal module, causing light leakage in the frame of the liquid crystal module. By providing a bevel gear set on the curved arm, the rotational force of the curved arm is converted through the bevel gear set, thereby realizing the rotation of the optical axis. Because the rotation of the optical axis drives the cam to rotate, the shading module connected to the cam through the plastic rope moves into the guide rail due to the rotation of the optical axis. When the liquid crystal module turns to the curved surface, the gap between the frame and the liquid crystal module is the largest, and the liquid crystal module moves outside the guide rail due to the thrust of the reset spring. The pulling of the plastic rope ensures that the shading module will not protrude excessively from the curved liquid crystal module frame, while ensuring that the liquid crystal module does not leak light when switching the curvature, the display effect of the liquid crystal module will not be affected by the protrusion of the shading module.

[0015] Preferably, the bevel gear set includes a first bevel gear and a second bevel gear, the first bevel gear and the second bevel gear are meshed, the first bevel gear is rotatably connected to the crank arm, the second bevel gear is fixedly connected to the frame, the optical axis is fixedly connected to the second bevel gear, a rubber block and a torsion spring are also sleeved in the cam, the rubber block is fixed in the cam and rotatably connected to the optical axis, the torsion spring is installed between the rubber block and the cam, and the front and rear ends are respectively connected to the cam and the optical axis.

[0016] It is easy to understand that when the angle between the curved arms changes, the first bevel gear rotates and drives the optical axis on the second bevel gear to rotate. The deformation caused by the friction of the rubber block ensures that the cam is connected to the optical axis when it is in any rotation direction. When the optical axis stops, that is, the deformation of the liquid crystal module is completed, the rubber block returns to its original state, and the cam returns to its original state due to the elastic force of the torsion spring, so that the shading module fits the deformed liquid crystal module frame again, making the arrangement of the shading module more uniform, thereby avoiding the shading module from squeezing and rubbing the liquid crystal module due to the deformation of the liquid crystal module, causing damage to the edge of the liquid crystal module and light leakage.

[0017] Preferably, the flexible slider is further provided with an arc surface portion, which is in a semicircular arc shape convex toward the flexible back plate, the arc surface portion is rotatably connected to the flexible slider, and a second torsion spring is further provided at the connection between the arc surface portion and the flexible slider.

[0018] It is easy to understand that when pressure is applied to the handle in the direction of the curved arm, the flexible slider extends out from the sliding groove, the telescopic frame shrinks into the sliding groove, and the length of the curved arm is shortened, so that there is margin on both sides of the frame of the liquid crystal module and it is no longer tight, until the flexible slider abuts against the flexible back plate. Due to the toughness of the flexible back plate itself, the flexible back plate is in an arc shape after abutting against the flexible slider, so that the frame shape of the liquid crystal module is in an arc shape, and through the setting of the arc portion, the curvature of the arc shape after the flexible back plate abuts against the flexible slider is the curvature of the arc portion, and when the curvature of the liquid crystal module returns to a plane, that is, the flexible slider retracts into the sliding groove, and the arc portion abuts against the curved arm due to the elastic force of the second torsion spring until the handle abuts against the abutting portion, and the rotation angle of the arc portion is expanded to the maximum, thereby avoiding the contact between the arc portion and the flexible back plate, thereby ensuring the accuracy of the curvature of the liquid crystal module.

[0019] Preferably, a shading plate is further provided inside the side edge of the frame, and the upper and lower end surfaces of the shading plate are respectively slidably connected to the frame and the liquid crystal module, a guide groove with rounded corners is provided between the flexible back panel and the frame, and a compensation groove is also provided at the edge of the flexible back panel of the shading plate, and the compensation groove is connected to the flexible back panel through a compensation spring.

[0020] It is easy to understand that in order to prevent the left and right side frames of the liquid crystal module from generating gaps with the deformed frame due to the change in curvature, thereby causing light leakage on the left and right sides of the liquid crystal module, a shading plate is provided in the side edge of the frame. The deformed frame is less soft than the liquid crystal module, so a gap appears between the two. The flexible backplane moves into the gap due to the thrust of the compensation spring in the compensation groove, and fills the gap through the guidance of the guide groove. When the liquid crystal module returns to a plane, the shading plate is squeezed to the edge of the flexible backplane by the liquid crystal module due to the reduction of the gap, thereby ensuring that there is no light leakage on the left and right sides of the liquid crystal module, thereby ensuring the display effect of the liquid crystal module after the curvature is switched.

[0021] Preferably, a retention portion is further provided in the first bevel gear, and the retention portion is in a circular shape composed of two semicircles with different radii. A convex circle is also provided on the curved arm, and the convex circle rotates along the semicircular surface with the largest radius of the retention portion. A torsion spring is also sleeved on the convex circle. A boss is also provided on the lower end surface of the first bevel gear, and the boss is located in the sliding groove. The sliding groove is also slidably connected to a screw rod, and a button is slidably connected to the handle, and the two ends of the screw rod are respectively abutted against the boss and the button.

[0022] It is easy to understand that before the curvature of the liquid crystal module is switched, the button on the handle is squeezed to drive the screw to push the boss, and the first bevel gear rotates due to the movement of the boss. Due to the setting of the retention part, the first bevel gear can rotate first until the convex circle abuts against the semicircular surface with the largest radius of the retention part. Before the abutment, the rotation of the first bevel gear drives the cam to rotate, thereby driving the shading module to retract into the guide rail in advance. After the abutment, the first bevel gear rotates synchronously with the curved arm due to the switching of the curvature of the liquid crystal module. When the curvature switching is completed, the squeezing of the button is released, and the boss is reset due to the elastic force of the torsion spring. During the resetting process, the retention part slides on the convex circle, and the convex circle is fixed due to the friction force of the gasket damping, thereby avoiding the shading module from squeezing and rubbing the liquid crystal module due to the deformation of the liquid crystal module, causing damage to the edge of the liquid crystal module.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention provides an adjustment component, a flexible back panel and a handle, and ensures that the change of the curvature of the liquid crystal module remains consistent through the cooperation of a curved arm and an adjustment rack. By pressing the handle into the sliding groove, the flexible slider stretches the telescopic frame while moving away from the flexible back panel, so that the liquid crystal module is stretched and tensioned due to the elongation of the curved arm, thereby changing the liquid crystal module from a convex circular surface to a flat surface. By pressing the handle toward the center line of the flexible back panel and limiting the rotation of the rotating teeth through a limit block, the liquid crystal module is changed from a flat surface to a curved surface with a curvature suitable for long-term observation by the human eye, thereby achieving the purpose of simply and accurately changing the curvature of the liquid crystal module.

[0025] 2. The present invention arranges a rubber block and a torsion spring, and the deformation caused by the friction of the rubber block ensures the connection between the cam and the optical axis when the optical axis is in any rotation direction. When the optical axis stops, that is, when the deformation of the liquid crystal module is completed, the rubber block returns to its original state, and the cam returns to its original state due to the elastic force of the torsion spring, so that the shading module fits the deformed liquid crystal module frame again, thereby avoiding the shading module from squeezing and rubbing the liquid crystal module due to the deformation of the liquid crystal module, causing damage to the edge of the liquid crystal module and light leakage.

[0026] 3. The present invention sets the arc surface part, when the pressure in the direction of the curved arm is applied to the handle, the flexible slider extends from the sliding groove, the telescopic frame contracts into the sliding groove, and the length of the curved arm is shortened, so that margins appear on both sides of the frame of the liquid crystal module and it is no longer tight until the flexible slider abuts against the flexible back plate. Due to the toughness of the flexible back plate itself, the flexible back plate is in an arc shape after abutting against the flexible slider, so that the frame shape of the liquid crystal module is in an arc shape, and the setting of the arc surface part makes the curvature of the arc shape after the flexible back plate abuts against the flexible slider be the curvature of the arc surface part, thereby ensuring the accuracy of the curvature of the liquid crystal module.

[0027] 4. The present invention sets a retention part and a torsion spring, and squeezes the button on the handle to drive the screw to push the boss. The first bevel gear rotates due to the movement of the boss. Due to the setting of the retention part, the first bevel gear can rotate first until the convex circle abuts against the semicircular surface with the largest radius of the retention part. Before the abutment, the rotation of the first bevel gear drives the cam to rotate, thereby driving the shading module to retract into the guide rail in advance. After the abutment, the first bevel gear rotates synchronously with the crank arm, thereby avoiding the shading module from squeezing and rubbing the liquid crystal module due to the deformation of the liquid crystal module, causing damage to the edge of the liquid crystal module.

The telescopic frame 6 shrinks into the sliding groove 403, and the length of the curved arm 401 is shortened, so that the two sides of the frame of the liquid crystal module 1 have margins and are no longer tight, until the flexible slider 7 and the flexible back plate 3 are aligned. The flexible back plate 3 is abutted against the flexible slider 7. Due to the toughness of the flexible back plate 3 itself, the flexible back plate 3 is in an arc shape after abutting against the flexible slider 7, so that the frame shape of the liquid crystal module 1 is in an arc shape. The arc portion 702 is set so that the curvature of the arc shape after the flexible back plate 3 abuts against the flexible slider 7 is the curvature of the arc portion 702. When the curvature of the liquid crystal module 1 is restored to a plane, that is, the flexible slider 7 is retracted into the sliding groove 403, the arc portion 702 abuts against the curved arm 401 due to the elastic force of the second torsion spring 703, until the handle 5 abuts against the abutting portion 4031, and the rotation angle of the arc portion 702 is expanded. To the maximum, thereby avoiding the contact between the arc portion 702 and the flexible back panel 3, thereby ensuring the accuracy of the curvature of the liquid crystal module 1. In the above process, the telescopic frame 6 moves into the sliding groove 403 due to the rotation of the gear 4012, so that the length of the curved arm 401 is shortened until the flexible slider 7 abuts against the flexible back panel 3. At this time, the liquid crystal module 1 has convex arc surfaces on the left and right sides due to the influence of the length of the flexible slider 7 and the curved arm 401 and the flexibility of the flexible back panel 3, thereby realizing the switching of the curvature of the convex circular 4013 arc surface when the liquid crystal module 1 is in a plane.The liquid crystal module 1 is stretched and tensioned due to the elongation of the curved arm 401, thereby changing the liquid crystal module 1 from a convex round 4013 surface to a flat surface; when the user wants to enhance the immersion in watching movies or some racing games, the user can press the handle 5 toward the center line of the flexible back plate 3 to reduce the angle of the curved arm 401, and by setting a mirror-symmetrical rotating tooth 4011 on the curved arm 401 and adjusting the gear rack 402 to mesh with the rotating tooth 4011, when the user presses the handle 5 toward the center line of the flexible back plate 3, the curved arm 401 is 01, because the adjustment rack 402 is meshed with the rotating teeth 4011 on both sides, the rotation angles of the rotating teeth 4011 on both sides are the same, so that the curvatures on both sides of the center line of the flexible back plate 3 are exactly the same, and the adjustment rack 402 and the crank arm 401 are connected with the rear end surface of the flexible back plate 3 at three points, while ensuring the curvature of both sides of the flexible back plate 3, the problem of the curved surface direction of the flexible back plate 3 changing due to the extrusion of the crank arm 401 will not occur; at the same time, by providing a limit block 4021 on the adjustment rack 402 The limiting block 4021 is in contact with the rotating gear 4011, thereby limiting the steering angle of the crank arm 401, thereby ensuring that the user can adjust the curvature to the desired curvature in one step, and by setting a gasket 405 between the rotating shaft 404 and the crank arm 401, by tightening the screw 406, the damping between the crank arm 401 and the rotating shaft 404 is adjusted, and the curvature of the liquid crystal module 1 is accurately changed through the coordination of the mechanical structure. The structure is simple and easy to maintain, and the use of electronic devices such as servo motors is avoided. The device may be damaged during use. While ensuring that the curvature of the liquid crystal module 1 can be adjusted by manpower, it also ensures that external force cannot affect the curvature of the liquid crystal module 1, thereby realizing the switching of the curvature of the curved surface of the liquid crystal module 1 when it is flat, so that the liquid crystal module 1 is changed from a flat surface to a curved surface with a curvature suitable for long-term observation by the human eye. The coordination of the curved arm 401 and the adjustment rack 402 ensures that the curvature changes on both sides of the center line of the liquid crystal module 1 remain consistent, thereby achieving the purpose of simply and accurately changing the curvature of the liquid crystal module 1.

[0044] Because the frame 2 needs to maintain its hardness and lightness while deforming with the liquid crystal module 1, it is inevitable that the curvature of the frame 2 on all sides is completely consistent with that of the liquid crystal module 1 when deforming, thereby generating a gap between the frame 2 and the liquid crystal module 1, causing light leakage from the frame of the liquid crystal module 1. By arranging a bevel gear set 102 on the crank arm 401, the rotation force of the crank arm 401 is converted through the bevel gear set 102, thereby realizing the rotation of the optical axis 103. Because the rotation of the optical axis 103 drives the cam 104 to rotate, the plastic rope 1041 connected to the cam 104 The shading module 101 moves inside the guide rail 1011 due to the rotation of the optical axis 103, and when the liquid crystal module 1 turns to the curved surface, the gap between the frame 2 and the liquid crystal module 1 is the largest, and the liquid crystal module 1 moves outside the guide rail 1011 due to the thrust of the return spring 1012. The pulling of the plastic rope 1041 ensures that the shading module 101 will not protrude excessively and deform into the curved liquid crystal module 1 frame. While ensuring that the liquid crystal module 1 does not leak light when switching the curvature, the display effect of the liquid crystal module 1 will not be affected by the protrusion of the shading module 1. The deformation caused by friction ensures that the cam 104 is connected to the optical axis 103 when it is in any rotation direction. When the optical axis 103 stops, that is, the deformation of the liquid crystal module 1 is completed, the rubber block 1042 returns to its original state, and the cam 104 returns to its original state due to the elastic force of the torsion spring 1043, so that the shading module 101 is re-fitted to the deformed frame of the liquid crystal module 1, so that the arrangement of the shading module 101 is more uniform, thereby avoiding the shading module 101 from squeezing and rubbing the liquid crystal module 1 due to the deformation of the liquid crystal module 1, causing damage to the edge of the liquid crystal module 1 and light leakage. 2, a shading plate 201 is provided in the side edge of the frame 2, and the deformed frame 2 is less flexible than the liquid crystal module 1, so that a gap appears between the two. The flexible back plate 3 moves into the gap due to the thrust of the compensation spring 203 in the compensation groove 2011, and fills the gap through the guidance of the guide groove 202. When the liquid crystal module 1 returns to the plane, the shading plate 201 is squeezed to the edge of the flexible back plate 3 by the liquid crystal module 1 due to the reduction of the gap, thereby ensuring that there is no light leakage on the left and right sides of the liquid crystal module 1, thereby ensuring the display effect of the liquid crystal module 1 after the curvature is switched.

[0045] Before the curvature of the liquid crystal module 1 is switched, the button 501 on the handle 5 is squeezed to drive the screw 1026 to push the boss 1025, and the first bevel gear 1021 rotates due to the movement of the boss 1025. Due to the setting of the retention part 1023, the first bevel gear 1021 can be rotated first until the convex circle 4013 abuts against the semicircular surface with the largest radius of the retention part 1023. Before the abutment, the rotation of the first bevel gear 1021 drives the cam 104 to rotate, thereby driving the shading module 101 to retract into the guide rail 1011 in advance. Afterwards, the first bevel gear 1021 rotates synchronously with the curved arm 401 due to the switching of the curvature of the liquid crystal module 1. When the curvature switching is completed, the squeezing of the button 501 is released, and the boss 1025 is reset due to the elastic force of the torsion spring 1024. During the resetting process, the retention portion 1023 slides on the convex circle 4013, and the convex circle 4013 is fixed due to the friction force damped by the gasket 405, thereby avoiding the shading module 101 from squeezing and rubbing the liquid crystal module 1 due to the deformation of the liquid crystal module 1, causing damage to the edge of the liquid crystal module 1.
