Description

Technical Field

[0001] This application belongs to the field of vehicle technologies, and particularly relates to a screen rotation device and a vehicle. Background Art

[0002] In the prior art, to meet the needs of users, in-vehicle screens have been applied in vehicles to improve the comprehensive performance of the vehicles. To reduce the impact of the in-vehicle screen on the vehicle interior space, a vehicle is usually provided with a screen flipping mechanism. When the in-vehicle screen needs to be used, the in-vehicle screen can be unfolded through the flipping mechanism. When the use of the in-vehicle screen is finished, the in-vehicle screen can be retracted through the flipping mechanism. Thus, it is possible to prevent the in-vehicle screen from occupying too much space in the vehicle.

[0003] However, in the existing in-vehicle screen, a screen flipping mechanism and an angle monitoring mechanism are respectively connected to opposite ends of the screen. Among them, the screen flipping mechanism drives the in-vehicle screen to rotate, and the rotation of the in-vehicle screen drives the angle monitoring mechanism to rotate. Due to manufacturing and installation errors of parts, it is difficult to accurately ensure the concentricity between the output shaft of the screen flipping mechanism and the mounting hole for mounting the output shaft of the angle monitoring mechanism. When the concentricity deviation between the output shaft of the screen flipping mechanism and the mounting hole for mounting the output shaft of the angle monitoring mechanism is relatively large, the operation of the flipping mechanism will cause the in-vehicle screen to be distorted or damaged, affecting the service life of the in-vehicle screen.

[0034] Next, the technical solutions of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described implementation manners are only a part of the implementation manners of the present application, rather than all the implementation manners. Based on the implementation manners in the present application, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0035] The description of the following embodiments refers to the attached drawings for exemplifying specific embodiments in which the present application can be implemented.

Therefore, the directional terms used are for better and clearer illustration and understanding of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. In the description of the present application, the "connection" and "coupling" involved, unless otherwise specified, include both direct connection (coupling) and indirect connection (coupling).

[0036] In the current in-vehicle technology field, to meet the needs of users, in-vehicle screens have been applied in vehicles to improve the comprehensive performance of the vehicles. To reduce the impact of the in-vehicle screen on the interior space of the vehicle, the vehicle is usually provided with a screen flipping mechanism. When the in-vehicle screen is needed, the in-vehicle screen can be unfolded through the flipping mechanism. When the use of the in-vehicle screen is ended, the in-vehicle screen can be retracted through the flipping mechanism. Thus, it is possible to avoid the in-vehicle screen occupying too much space in the vehicle.

[0037] However, in the existing in-vehicle screen, a screen flipping mechanism and an angle monitoring mechanism are respectively connected to opposite ends. Among them, the screen flipping mechanism drives the in-vehicle screen to rotate, and the rotation of the in-vehicle screen drives the angle monitoring mechanism to rotate. Due to manufacturing and installation errors of parts, it is difficult to accurately ensure the concentricity between the output shaft of the screen flipping mechanism and the input shaft of the angle monitoring mechanism. When the concentricity deviation between the output shaft of the screen flipping mechanism and the input shaft of the angle monitoring mechanism is relatively large, the operation of the flipping mechanism will cause the in-vehicle screen to be distorted or damaged, affecting the service life of the in-vehicle screen.

[0038] To solve the above technical problems, the present application provides a screen rotation device and a vehicle that can improve the service life of the in-vehicle display screen.

[0039] The present application provides a vehicle, on which a screen rotation device is provided. The screen rotation device provided by the present application is beneficial to improving the service life of the screen rotation device during the rotation process.

[0040] Please refer to Figures 1 to 3 , Figure 1 which is an assembly structure of a screen rotation device provided by an embodiment of the present application Figure 1 , Figure 2 which is an assembly structure of a screen rotation device provided by an embodiment of the present application Figure 2 , Figure 3It is an assembly structure of a screen rotation device provided by an embodiment of the present application Figure 3 。

[0041] This embodiment provides a screen rotation device 100, which includes a base 10, a display screen 20, a flipping mechanism 30, a monitoring mechanism 40, and a locking tongue mechanism 50.

[0042] As Figure 1 and Figure 2 shown, the base 10 is installed on the vehicle, and the display screen 20 is rotatably installed on the base 10 so that the display screen 20 can rotate relative to the base 10. Figure 1 The screen rotation device 100 shown is in the initial state, that is Figure 1 in the screen rotation device 100 shown, the display screen 20 is closed relative to the base 10, and the plane where the display screen 20 is located is parallel to the plane where the base 10 is located. Figure 2 The screen rotation device 100 shown is in the working state, that is Figure 2 in the screen rotation device 100 shown, the display screen 20 is opened relative to the base 10, and the plane where the display screen 20 is located is parallel to the plane where the base 10 is located.

[0043] As Figure 3 shown, the flipping mechanism 30 is connected between the base 10 and the display screen 20. The flipping mechanism 30 is used to drive the display screen 20 to rotate relative to the base 10, thereby realizing the flip function of the display screen 20, that is, the flipping mechanism 30 is used to drive the display screen 20 to open or close relative to the base 10. Through the setting of the flipping mechanism 30, it is convenient for the user to rotate the display screen 20 of the screen rotation device 100 relative to the base 10.

[0044] As Figure 3 shown, the monitoring mechanism 40 is connected between the base 10 and the display screen 20. The monitoring mechanism 40 can rotate as the display screen 20 rotates relative to the base 10. The monitoring mechanism 40 is used to monitor the rotation angle of the display screen 20 relative to the base 10. Through the setting of the monitoring mechanism 40, it is convenient for the user to judge the rotation angle of the display screen 20 relative to the base 10.

[0045] Please refer to Figures 1 to 4 , Figure 4 It is a structural diagram of a locking tongue mechanism provided by an embodiment of the present application.

[0046] The locking tongue mechanism 50 is disposed on the base 10, and the locking tongue mechanism 50 is used to detachably fix the display screen 20 to the base 10. The locking tongue mechanism 50 includes a fixing member 51 and a locking member 52. The fixing member 51 is fixed to the base 10, and the locking member 52 is movably disposed on the fixing member 51. The locking member 52 can be received in the fixing member 51 or protrude from the fixing member 51. The locking member 52 of the locking tongue mechanism 50 protrudes from the fixing member 51 and can lock the display screen 20 to the base 10 so that the display screen 20 can be fixed relative to the base 10. The locking member 52 of the locking tongue mechanism 50 retracts and is received in the mounting seat, and can unlock the display screen 20 from the base 10 so that the display screen 20 can rotate relative to the base 10. Through the arrangement of the locking tongue mechanism 50, it is beneficial to improve the structural stability of the screen rotating device 100 in the initial state, and at the same time, it is also convenient for the screen rotating device 100 to switch from the initial state to the working state.

[0047] In this embodiment, the number of the locking tongue mechanisms 50 in the screen rotating device 100 is two, and the two locking tongue mechanisms 50 are disposed on opposite sides of the display screen 20. Through the arrangement of the two locking tongue mechanisms 50, it is beneficial to further improve the structural stability of the screen rotating device 100 in the initial state.

[0048] It can be understood that in some other embodiments, the number of the locking tongue mechanisms 50 in the screen rotating device 100 can be one, three, four, etc., and the present application does not limit this.

[0049] Please refer to Figure 5 , Figure 5 which is a structural diagram of a screen rotating device provided by the first embodiment of the present application.

[0050] In the first embodiment of the present application, the screen rotating device 100 includes a base 10 and a display screen 20, and the display screen 20 is rotatably connected to the base 10. The base 10 has a first hole 11 and a second hole 12. Opposite sides of the display screen 20 have a first shaft 21 and a second shaft 22. The first shaft 21 extends into the first hole 11 and rotatably contacts the inner sidewall of the first hole 11, and the second shaft 22 rotatably extends into the second hole 12 and rotatably contacts the inner sidewall of the second hole 12. A partial area of the circumferential sidewall of the first shaft 21 is movably connected to a partial area of the inner sidewall of the first hole 11, and there is a gap N between the circumferential sidewall of the first shaft 21 and the inner sidewall of the first hole 11. During the rotation of the first shaft 21, the axis of the first shaft 21 can form an inclined angle with the center line of the first hole 11.

[0051] The screen rotation device 100 provided by the present application is rotatably arranged in the first hole 11 through the first shaft 21 of the display screen 20, and the second shaft 22 of the display screen 20 is rotatably arranged in the second hole 12, so that the display screen 20 can rotate relative to the base 10, thereby realizing the flip function of the display screen 20. At the same time, since a partial area of the circumferential side wall of the first shaft 21 is movably connected to a partial area of the inner side wall of the first hole 11, and there is a gap N between the circumferential side wall of the first shaft 21 of the display screen 20 extending into the first hole 11 and the inner side wall of the first hole 11. During the rotation of the first shaft 21, the axis of the first shaft 21 can form an inclined angle with the center line of the first hole 11, that is, the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 during rotation, so that the axis of the first shaft 21 can be adjusted to a state collinear with the axis of the second shaft 22, which can reduce the resistance received by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the twisting force received by the display screen 20 during rotation can be reduced, making the display screen 20 smoother during the flipping process, which is beneficial to improving the service life of the display screen 20.

[0052] In a specific embodiment, the movable connection between the circumferential side wall of the first shaft 21 and the inner side wall of the first hole 11 is a pivot connection. Since the first shaft 21 extends into the first hole 11 and is in rotational contact with the inner side wall of the first hole 11, the first shaft 21 can rotate in the first hole 11 around the center line direction of the first hole 11. Since there is a gap N between the circumferential side wall of the first shaft 21 of the display screen 20 extending into the first hole 11 and the inner side wall of the first hole 11, the first shaft 21 can swing radially along the first hole 11 in the first hole. Thus, the first shaft 21 can rotate and swing in the first hole 11, so that the axis of the first shaft 21 can be adjusted to a state collinear with the axis of the second shaft 22, which can reduce the resistance received by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the twisting force received by the display screen 20 during rotation can be reduced, making the display screen 20 smoother during the flipping process, which is beneficial to improving the service life of the display screen 20.

[0053] It can be understood that in some other embodiments, the first hole 11 and the second hole 12 can be arranged on the display screen 20, the first shaft 21 and the second shaft 22 can be arranged on the base 10, the first shaft 21 extends into the first hole 11 and can rotate in the first hole 11, and the second shaft 22 extends into the second hole 12 and can rotate in the second hole 12, which can also realize the flipping of the display screen 20 relative to the base 10, and the present application does not limit this.

[0054] It can be understood that in some other embodiments, the first hole 11 and the second shaft 22 may be provided on the display screen 20, the first shaft 21 and the second hole 12 may be provided on the base 10, the first shaft 21 extends into the first hole 11 and can rotate within the first hole 11, and the second shaft 22 extends into the second hole 12 and can rotate within the second hole 12, which can also achieve the flipping of the display screen 20 relative to the base 10, and the present application does not limit this.

[0055] It can be understood that in some other embodiments, the first shaft 21 and the second hole 12 may be provided on the display screen 20, the first hole 11 and the second shaft 22 may be provided on the base 10, the first shaft 21 extends into the first hole 11 and can rotate within the first hole 11, and the second shaft 22 extends into the second hole 12 and can rotate within the second hole 12, which can also achieve the flipping of the display screen 20 relative to the base 10, and the present application does not limit this.

[0056] Please refer to Figure 5 and Figure 6 , Figure 6 which is a cross-sectional view of a monitoring mechanism provided by the first embodiment of the present application.

[0057] In a specific embodiment, a protrusion M is provided on the circumferential side wall of the part of the first shaft 21 extending into the first hole 11. The protrusion M is in sliding contact with the inner side wall of the first hole 11. The protrusion M divides the gap N formed between the circumferential side wall of the first shaft 21 and the inner side wall of the first hole 11 into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the circumferential sides of the opposite ends of the protrusion M along the first shaft 21.

[0058] In the screen rotation device 100 provided by the present application, the protrusion M on the circumferential side wall of the first shaft 21 is in sliding contact with the inner side wall of the first hole 11, and the protrusion M divides the gap N between the circumferential side wall of the first shaft 21 and the inner side wall of the first hole 11 into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the circumferential sides of the opposite ends of the protrusion M along the first shaft 21. When the display screen 20 rotates relative to the base 10, the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 during rotation, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22, which can reduce the resistance received by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the torsional force acting on the display screen 20 during rotation can be reduced, making the display screen 20 smoother during flipping, which is beneficial to improving the service life of the display screen 20.

[0059] It can be understood that in some other embodiments, the screen rotation device 100 may further include a plurality of rolling elements. The plurality of rolling elements are circumferentially and uniformly distributed between the outer sidewall of the first shaft 21 and the inner sidewall of the first hole 11 around the first axis 21. The plurality of rolling elements divide the gap N formed between the circumferential sidewall of the first shaft 21 and the inner sidewall of the first hole 11 into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the circumferential sides of the opposite ends of the rolling elements along the first axis 21. The first shaft 21 can rotate in the first hole 11 under the action of the rolling elements, and the axis of the first shaft 21 can be offset relative to the center line of the first hole 11. In a specific embodiment, the rolling elements are spherical. In some other embodiments, the rolling elements can be rings, and the rings are sleeved on the first shaft 21, and the cross-section of the rings is circular.

[0060] In a more specific embodiment, the protrusion M is an arc protrusion M, and the protrusion M is arranged around the circumference of the first shaft 21. By the surface of the protrusion M being arc-shaped, the first shaft 21 can be inclined 360° relative to the center line of the first hole 11 in the first hole 11, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22, which can reduce the resistance received by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the twisting force received by the display screen 20 during rotation can be reduced, making the display screen 20 smoother during the flipping process, which is beneficial to improving the service life of the display screen 20.

[0061] It can be understood that in some other embodiments, the protrusion M can be an elliptical arc protrusion M, a "U"-shaped protrusion M, a "V"-shaped protrusion M, etc., and the present application does not limit this.

[0062] It can be understood that in some other embodiments, the protrusion M can be a plurality of arc protrusions M arranged at intervals, an open annular arc protrusion M, etc., and the present application does not limit this. It should be understood that when the protrusion M is an open annular arc protrusion M, the ring of the open annular arc needs to be greater than 0.5 rings, that is, the central angle corresponding to the arc protrusion M is greater than 180°, so that the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 in the first hole 11.

[0063] In a more specific embodiment, the center of the circle where the surface of the protrusion M is located is on the center line of the first hole 11. By the center of the circle where the surface of the protrusion M is located being on the center line of the first hole 11, the first shaft 21 can rotate more smoothly in the first hole 11.

[0064] Please refer to Figure 7 and Figure 8 , Figure 7 is a structural diagram of a screen rotation device provided by the second embodiment of the present application. Figure 8It is a cross-sectional view of a monitoring mechanism provided by the second embodiment of the present application.

[0065] The screen rotation device 100 provided by the second embodiment of the present application is substantially the same as the screen rotation device 100 provided by the first embodiment of the present application. The difference is that the first shaft 21 provided by the second embodiment of the present application is a cylindrical shaft, and there is no protrusion M on the surface of the first shaft 21. However, a protrusion M is provided on the inner side wall of the first hole 11 provided by the second embodiment of the present application. The protrusion M is in sliding contact with the peripheral side wall of the first shaft 21 extending into the first hole 11. The protrusion M divides the gap N into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the inner peripheral sides of the opposite ends of the protrusion M along the first hole 11.

[0066] For the screen rotation device 100 provided by the present application, the protrusion M on the inner side wall of the first hole 11 is in sliding contact with the peripheral side wall of the first shaft 21, and the protrusion M divides the gap N between the peripheral side wall of the first shaft 21 and the inner side wall of the first hole 11 into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the inner peripheral sides of the opposite ends of the protrusion M along the first hole 11. When the display screen 20 rotates relative to the base 10, the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 when the first shaft 21 rotates, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22, which can reduce the resistance received by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the torsional force acting on the display screen 20 during rotation can be reduced, making the display screen 20 more smooth during the flipping process, which is beneficial to improving the service life of the display screen 20.

[0067] Please refer to Figure 9 and Figure 10 , Figure 9 It is a structural diagram of a screen rotation device provided by the third embodiment of the present application. Figure 10 It is a cross-sectional view of a monitoring mechanism provided by the third embodiment of the present application.

[0068] The screen rotation device 100 provided by the third embodiment of the present application is substantially the same as the screen rotation device 100 provided by the first embodiment of the present application. The difference is that the cross-section of the protrusion M provided by the third embodiment of the present application in the direction of the axis of the first shaft 21 is rectangular. Moreover, a depression O is provided on the inner side wall of the first hole 11 provided by the second embodiment of the present application. At least part of the protrusion M is received in the depression O and is in sliding contact with the surface of the depression O. The protrusion M divides the gap N into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the peripheral sides of the opposite ends of the protrusion M along the first shaft 21.

[0069] The screen rotation device 100 provided by the present application has a protrusion M on the inner sidewall of the first hole 11 in sliding contact with a recess O on the circumferential sidewall of the first shaft 21. The protrusion M divides the gap N between the circumferential sidewall of the first shaft 21 and the inner sidewall of the first hole 11 into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the circumferential sides of the opposite ends of the protrusion M along the first shaft 21. When the display screen 20 rotates relative to the base 10, the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 during rotation, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22. This can reduce the resistance received by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the twisting force acting on the display screen 20 during rotation can be reduced, making the rotation of the display screen 20 smoother and conducive to improving the service life of the display screen 20.

[0070] In a specific embodiment, the center of the circle where the surface of the recess O is located lies on the center line of the first hole 11. By having the center of the circle where the surface of the recess O is located on the center line of the first hole 11, the first shaft 21 can be inclined 360° relative to the center line of the first hole 11 within the first hole 11, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22. This can reduce the resistance received by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the twisting force acting on the display screen 20 during rotation can be reduced, making the rotation of the display screen 20 smoother and conducive to improving the service life of the display screen 20.

The flipping mechanism 30 and the monitoring mechanism 40 are both disposed on the base 10, and the flipping mechanism 30 and the monitoring mechanism 40 are respectively disposed on opposite sides of the display screen 20. Among them, the flipping mechanism 30 includes a driving member 31 and a second bracket 32 (the first bracket 42 will be described later). The driving member 31 is in transmission connection with the second bracket 32, and the driving member 31 is configured to drive the second bracket 32 to rotate. The second bracket 32 is fixedly connected to the display screen 20, and the driving member 31 drives the display screen 20 to rotate by driving the second bracket 32 to rotate. The monitoring mechanism 40 includes an angle detection component 41 and a first bracket 42. The first bracket 42 is fixedly connected to the display screen 20. The rotation of the display screen 20 drives the first bracket 42 to rotate. The angle detection component 41 is configured to detect the rotation angle of the first bracket 42, and thus the rotation angle of the display screen 20 can be determined.

[0073] It should be understood that in this embodiment, the connection manner between the driving member 31 and the second bracket 32 is similar to the connection manner between the second shaft 22 and the second hole 12. The connection manner between the angle detection component 41 and the first bracket 42 is similar to the connection manner between the first shaft 21 and the first hole 11.

[0074] It can be understood that in some other embodiments, the flipping mechanism 30 of the screen rotation device 100 can be omitted, and the user can manually drive the display screen 20 to rotate relative to the base 10. The present application does not limit this.

[0075] Please refer to Figure 11 and Figure 12 , in this embodiment, the monitoring mechanism 40 includes an angle detection component 41 and a first bracket 42. Among them, the angle detection component 41 includes an upper cover 411, a gear shaft 412, a potentiometer 413, a gear 414, a backlash damping 415, a lower cover 416, a gasket 417, a snap ring 418, and a spring 419.

[0076] The assembly process of the monitoring mechanism 40 is as follows:

[0077] Step 1: Assemble the backlash damping 415 into one end of the lower cover 416;

[0078] Step 2: Pass the gear shaft 412 through the backlash damping 415 and penetrate the lower cover 416;

[0079] Step 3: Assemble the gasket 417 and the spring 419 into the other end of the lower cover 416 in sequence, and make the gasket 417 and the spring 419 sleeved outside the gear shaft 412; then press the snap ring 418 into the gear shaft 412 through a tooling, and make the snap ring 418 sleeved outside the gear shaft 412;

[0080] Step 4: Snap the potentiometer 413 into the upper cover 411, assemble the gear 414 inside one end of the lower cover 416, and then fix the upper cover 411 and the lower cover 416.

[0081] Step 5: Assemble the first bracket 42 inside the gear shaft 412.

[0082] Please refer to Figure 6 , the first shaft 21 is arranged on the first bracket 42, the first hole 11 is arranged on the gear shaft 412, the second shaft 22 is arranged on the driving member 31, and the second hole 12 is arranged on the second bracket 32.

[0083] The first shaft 21 extends into the first hole 11 and makes rotational contact with the inner sidewall of the first hole 11. There is a gap N between the circumferential sidewall of the first shaft 21 and the inner sidewall of the first hole 11. Part of the circumferential sidewall of the first shaft 21 makes sliding contact with part of the inner sidewall of the first hole 11, so that the axis of the first shaft 21 deflects when the first shaft 21 rotates.

[0084] For the screen rotation device 100 provided in this application, since there is a gap N between the circumferential sidewall of the first shaft 21 extending into the first hole 11 and the inner sidewall of the first hole 11, and part of the circumferential sidewall of the first shaft 21 extending into the first hole 11 makes sliding contact with part of the inner sidewall of the first hole, the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 when the first shaft 21 rotates. Furthermore, the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22, which can reduce the resistance received by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the twisting force received by the display screen 20 during rotation can be reduced, making the display screen 20 smoother during the flipping process, which is beneficial to improving the service life of the display screen 20.

[0085] In a specific embodiment, a protrusion M is provided on the circumferential sidewall of the part of the first shaft 21 extending into the first hole 11. The protrusion M makes sliding contact with the inner sidewall of the first hole 11. The protrusion M divides the gap N formed between the circumferential sidewall of the first shaft 21 and the inner sidewall of the first hole 11 into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are arranged on the circumferential sides of the opposite ends of the protrusion M along the first shaft 21.

[0086] The screen rotation device 100 provided by this application has a protrusion M on the circumferential sidewall of the first shaft 21 that is in sliding contact with the inner sidewall of the first hole 11. The protrusion M divides the gap N between the circumferential sidewall of the first shaft 21 and the inner sidewall of the first hole 11 into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the circumferences of the opposite ends of the protrusion M along the first shaft 21. When the display screen 20 rotates relative to the base 10 through the flipping mechanism 30, the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 during rotation, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22. This can reduce the resistance suffered by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the twisting force acting on the display screen 20 during rotation can be reduced, making the display screen 20 more smooth during the flipping process, which is beneficial to improving the service life of the display screen 20.

[0087] In a more specific embodiment, the protrusion M is an arc protrusion M, and the protrusion M is arranged around the circumference of the first shaft 21. Since the surface of the protrusion M is arc-shaped, the first shaft 21 can be inclined 360° relative to the center line of the first hole 11 within the first hole 11, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22. This can reduce the resistance suffered by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the twisting force acting on the display screen 20 during rotation can be reduced, making the display screen 20 more smooth during the flipping process, which is beneficial to improving the service life of the display screen 20.

[0088] It can be understood that in some other embodiments, the protrusion M can be an elliptical arc protrusion M, a "U"-shaped protrusion M, a "V"-shaped protrusion M, etc. This application does not limit this.

[0089] It can be understood that in some other embodiments, the protrusion M can be multiple spaced arc protrusions M, an open-ring arc protrusion M, etc. This application does not limit this. It should be understood that when the protrusion M is an open-ring arc protrusion M, the ring of the open-ring arc needs to be greater than 0.5 rings, that is, the central angle corresponding to the arc protrusion M is greater than 180°, so that the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 within the first hole 11.

[0090] In a more specific embodiment, the center of the circle where the surface of the protrusion M is located is on the center line of the first hole 11. Since the center of the circle where the surface of the protrusion M is located is on the center line of the first hole 11, the first shaft 21 rotates more smoothly within the first hole 11.

[0091] Please refer to Figure 8, the first shaft 21 is disposed on the first bracket 42, the first hole 11 is disposed on the gear shaft 412, the second shaft 22 is disposed on the driving member 31, and the second hole 12 is disposed on the second bracket 32.

[0092] In this embodiment, the first shaft 21 is a cylindrical shaft, and there is no protrusion M on the surface of the first shaft 21. However, a protrusion M is provided on the inner side wall of the first hole 11 provided in this embodiment. The protrusion M is in sliding contact with the peripheral side wall of the first shaft 21 extending into the first hole 11. The protrusion M divides the gap N into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the inner peripheral sides at opposite ends of the protrusion M along the first hole 11.

[0093] For the screen rotation device 100 provided in this application, the protrusion M on the inner side wall of the first hole 11 is in sliding contact with the peripheral side wall of the first shaft 21, and the protrusion M divides the gap N between the peripheral side wall of the first shaft 21 and the inner side wall of the first hole 11 into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the inner peripheral sides at opposite ends of the protrusion M along the first hole 11. When the display screen 20 rotates relative to the base 10, the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 when the first shaft 21 rotates, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22, which can reduce the resistance suffered by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the twisting force acting on the display screen 20 during rotation can be reduced, making the display screen 20 smoother during the flipping process, which is beneficial to improving the service life of the display screen 20.

[0094] Please refer to Figure 10 , the first shaft 21 is disposed on the first bracket 42, the first hole 11 is disposed on the gear shaft 412, the second shaft 22 is disposed on the driving member 31, and the second hole 12 is disposed on the second bracket 32.

[0095] In this embodiment, the cross-section of the protrusion M in the direction of the axis of the first shaft 21 is rectangular. Moreover, a recess O is provided on the inner side wall of the first hole 11 provided in this embodiment. At least part of the protrusion M is received in the recess O and is in sliding contact with the surface of the recess O. The protrusion M divides the gap N into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the peripheral sides at opposite ends of the protrusion M along the first shaft 21.

[0096] The screen rotation device 100 provided by this application has a protrusion M on the inner sidewall of the first hole 11 in sliding contact with a recess O on the circumferential sidewall of the first shaft 21. The protrusion M divides the gap N between the circumferential sidewall of the first shaft 21 and the inner sidewall of the first hole 11 into a first gap N1 and a second gap N2. The first gap N1 and the second gap N2 are provided on the circumferential sides of the opposite ends of the protrusion M along the first shaft 21. When the display screen 20 rotates relative to the base 10, the axis of the first shaft 21 can be inclined relative to the center line of the first hole 11 during rotation, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22. This can reduce the resistance suffered by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the torsional force acting on the display screen 20 during rotation can be reduced, making the display screen 20 more smooth during the flipping process, which is beneficial to improving the service life of the display screen 20.

[0097] In a specific embodiment, the center of the circle where the surface of the recess O is located lies on the center line of the first hole 11. By having the center of the circle where the surface of the recess O is located on the center line of the first hole 11, the first shaft 21 can be inclined 360° relative to the center line of the first hole 11 within the first hole 11, so that the axis of the first shaft 21 can be adjusted to be collinear with the axis of the second shaft 22. This can reduce the resistance suffered by the first shaft 21 during rotation. During the process of the user flipping the display screen 20, the torsional force acting on the display screen 20 during rotation can be reduced, making the display screen 20 more smooth during the flipping process, which is beneficial to improving the service life of the display screen 20.
