Therefore, the circumferential arrangement range of the first engagement teeth can be set wider. Therefore, compared with the prior art, the technical solution provided by the present application can overcome the technical problem of narrow pitch angle range of the display caused by insufficient torque.

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0037] In the description of the present application, it needs to be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can be explicitly or implicitly included one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0038] In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described as exemplary in this application is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the application. In the following description, for purposes of explanation, specific details are set forth. It will be apparent to those skilled in the art that the present application can be practiced without the specific details. In other instances, well-known structures and processes are not shown in detail to avoid obscuring the application. Thus, the present application is not intended to be limited by the implementations shown, but is to be accorded the widest scope consistent with the principles and features disclosed.

[0039] Display hinges are widely used in computer equipment, including the display of a general desktop computer or a notebook computer display. The basic function of the hinge is to allow the display to be easily adjusted to the individual needs of the user, and when the display is adjusted to any tilt angle, the display can remain stationary and not freely sag due to the weight of the display itself.

[0040] In the related prior art, the traditional hinge is locked on the back plate of the display. The maintenance components include a washer and a nut, and the forward force generated by the nut presses the washer to generate a damping torque, so that the display can stay at any position within its rotatable angle range. However, the hinge needs to bear the weight of the entire display, and when the display is at a large pitch angle, a large torque is needed to maintain the display at that position. However, the forward force generated by the screw lock is very limited, and the damping torque generated by the washer is limited, making it difficult to maintain the display at a large pitch angle.

[0041] To this end, the application provides a rotating shaft assembly 10, which is capable of rotating relative to its axis when a torque is applied and also capable of being kept in a preset position when the rotating shaft 12 is in the preset position, through the matching relationship between the engaging teeth on the rotating shaft 12 and the limiting teeth C on the sleeve 13.

[0042] Specifically, referring to Figure 1 The rotating shaft assembly 10 provided by the application includes a support 11, a rotating shaft 12 and a sleeve 13.

[0043] The support 11 is used to connect the housing 20 of the display 1.

[0044] The rotating shaft 12 is fixedly connected with the support 11. As Figure 2 The rotating shaft 12 is provided with a plurality of first engaging teeth A arranged along its circumference.

[0045] The sleeve 13 is used to connect the support 30 of the display 1. As Figure 3 or 4 shows, the sleeve 13 has limiting teeth C arranged on its inner surface. As Figure 1 The sleeve 13 is sleeved on the rotating shaft 12. The plurality of first engaging teeth A can all engage with the limiting teeth C, so that the support 11 can rotate relative to the axis of the sleeve 13, and the support 11 can be kept in the preset position based on the matching force generated by the limiting teeth C and at least one of the plurality of first engaging teeth A when it is rotated to the preset position.

[0046] In the specific implementation process, the support 11 is connected with the housing 20 of the display 1. The sleeve 13 is connected with the support 30 of the display 1. The rotating shaft 12 is fixedly connected with the support 11. The sleeve 13 is sleeved on the rotating shaft 12. And the plurality of first engaging teeth A arranged along the circumference of the rotating shaft 12 can all engage with the limiting teeth C on the inner surface of the sleeve 13. When it is necessary to adjust the pitch angle of the display 1, a certain torque is applied to the housing 20 of the display 1. At this time, since the housing 20 of the display 1 is connected with the support 11, the support 11 is fixedly connected with the rotating shaft 12, and the plurality of first engaging teeth A on the rotating shaft 12 all engage with the limiting teeth C on the inner surface of the sleeve 13, so that the support 11 can rotate relative to the axis of the rotating shaft 12 to drive the display 1 to rotate, thereby adjusting the pitch angle of the display 1. When it is adjusted to the preset position, the support 11 is kept in the preset position due to the matching force generated by the limiting teeth C and at least one of the plurality of first engaging teeth A, thereby maintaining the display 1 in the preset position.

[0047] When the display 1 is in the preset position state, the cooperation between the limiting teeth C and the first meshing teeth A generates a cooperation force, which is decomposed into a tangential force perpendicular to the radial direction of the rotating shaft 12, so that the rotating shaft 12 cannot rotate when no torque is applied, thereby maintaining the display 1 in the preset position state. Since the first meshing teeth A on the rotating shaft 12 are arranged along the circumferential direction, the preset angle range of the display 1 is determined by the circumferential arrangement range of the first meshing teeth A. Since the limiting teeth C can engage with at least one corresponding first meshing tooth A to generate a cooperation force, the limiting teeth C can limit the rotating shaft 12 to any position within the preset angle range, and thus the circumferential arrangement range of the first meshing teeth A can be wider. Therefore, compared with the prior art, the technical solution provided by the present application can overcome the technical problem of narrow pitch angle range of the display 1 caused by insufficient damping torque of the rotating shaft 12.

[0048] It should be noted that the first meshing teeth A are a plurality of. Adjacent two first meshing teeth A form a tooth groove. The limiting teeth C are embedded in the tooth groove, thereby realizing the engagement of the first meshing teeth A and the limiting teeth C. The plurality of first meshing teeth A are arranged along the circumferential direction of the rotating shaft 12, and the arrangement arc can determine the angle of the rotating shaft 12. The arrangement arc can be defined as the included angle between the line connecting the center of the first first meshing tooth A in the circumferential direction and the axis of the rotating shaft 12 and the line connecting the center of the last first meshing tooth A in the circumferential direction and the axis of the rotating shaft 12.

[0049] In the implementation, the arrangement arc of the first meshing teeth A is determined according to actual conditions, such as π / 12, π / 10, π / 8, π / 6, π / 4, π / 3, etc. That is, the pitch angle range of the display 1 can be [0, π / 12], [0, π / 10], [0, π / 8], [0, π / 6], [0, π / 4], [0, π / 3].

[0050] In order to improve the carrying capacity of the rotating shaft assembly 10, the maintaining capacity of the display 1 in the preset position state is improved. In the embodiment of the present application, as shown in Figure 2 The rotating shaft 12 includes a first section 121 and a second section 122 arranged along the circumferential direction. A first part A1 of the plurality of first meshing teeth A is arranged on the first section 121. A second part A2 of the plurality of first meshing teeth A is arranged on the second section 122. That is, the first meshing teeth A are arranged on the two sections of the rotating shaft 12 in the circumferential direction. As shown in Figure 3Or 4, the limit tooth C is a plurality of, a plurality of limit tooth C is arranged along the circumference, respectively with the first part A1 and the second part A2 are engaged. The first part A1 in a plurality of first meshing teeth A is arranged in the first section 121, the second part A2 in a plurality of second meshing teeth B is arranged in the second section 122, the first section 121 and the second section 122 are arranged along the circumference of the shaft 12; a plurality of limit tooth C is also segmented design, including the third part C1 and the fourth part C2 arranged along the circumference. Among them, the third part C1 of a plurality of limit tooth C is engaged with the first part A1, and the fourth part C2 of a plurality of limit tooth C is engaged with the second part A2. Because a plurality of limit tooth C is engaged with the first meshing tooth A of the first part A1 and the second part A2 arranged along the circumference, the limiting ability of the sleeve 13 to the shaft 12 can be improved, and the ability to maintain the display 1 in the preset position state can be improved.

[0051] In the specific implementation process, the arrangement mode of a plurality of limit tooth C can refer to as Figure 4 Generally speaking, the arrangement arc of a plurality of limit tooth C is consistent with or slightly larger than the arrangement arc of the first meshing tooth A. Therefore, when the display 1 rotates to the two endpoint values of the preset angle range, there is also a limit tooth C engaged with the first meshing tooth A to limit the rotation of the shaft 12.

[0052] As an optional implementation of the above embodiment, in order to keep the force balance of the shaft 12, as Figure 2 The first section 121 and the second section 122 are arranged symmetrically with the axis of the shaft 12. When the limit tooth C is engaged with the first meshing tooth A, each first meshing tooth A is subjected to the pressure (fitting force) of the limit tooth C, which can be decomposed into tangential force and radial force. The tangential force is perpendicular to the radial direction of the shaft 12, which generates a moment, and the moment is equal to the direction of the moment generated by the gravity of the display 1, which is used to maintain the display 1 in the preset position state. The radial force points to the shaft center of the shaft 12, and the first section 121 and the second section 122 are arranged symmetrically with the axis of the shaft 12, so that the resultant force of the radial force is 0, so that the shaft 12 keeps force balance.

[0053] The number of the first engagement teeth A engaging with the limiting teeth C is less when the display 1 is maintained near the two end point values of the preset angle range than when the display 1 is maintained near the middle value of the preset angle range, so the ability of the limiting teeth C to maintain the display 1 in the preset position state corresponding to the two end point values of the preset angle range is weaker than the ability of the limiting teeth C to maintain the display 1 in the preset position state corresponding to the middle value of the preset angle range. Moreover, the moment generated by the gravity of the display 1 is greater when the display 1 is maintained near the two end point values of the preset angle range, so the limiting ability of the limiting teeth C is kept unchanged. In some embodiments, as shown in Figure 2 The rotating shaft 12 further includes a third section 123 which is spaced apart from the first section 121 and the second section 122 in the axial direction of the rotating shaft 12. The third section 123 is provided with a plurality of second engagement teeth B arranged in the circumferential direction of the rotating shaft 12. A plurality of limiting teeth C are formed in the axial direction of the sleeve 13 and engage with the plurality of second engagement teeth B. That is, as shown in Figure 3 The plurality of limiting teeth C are arranged around the inner surface of the sleeve 13, extend in the axial direction, and engage with the second engagement teeth B on the third section 123. Thus, when the display 1 is maintained near the two end point values of the preset angle range, the display 1 is maintained in the preset position state near the two end point values of the preset angle range by the engagement between the second engagement teeth B on the third section 123 and the limiting teeth C, thereby improving the limiting ability of the sleeve 13. In addition, since the limiting teeth C engage with the second engagement teeth B, the resistance felt by the implementer when adjusting the pitch angle of the display 1 does not suddenly change.

[0054] Generally, the rotating shaft 12 and the support 11 can be fixedly connected by interference fit. However, this connection mode has high requirements for the manufacturing precision of the rotating shaft 12 and the support 11 and is difficult to disassemble. Therefore, as shown in Figure 8 The support 11 of the embodiment of the present application includes a support plate 111 and an ear 112 which extends in the thickness direction of the support plate 111 and is connected with the support plate 111. Figure 1 As shown in the figure, the ear 112 is provided with a shaft hole 112a, and the ear 112 is sleeved on the rotating shaft 12. Figure 8 As shown in the figure, the ear 112 is further provided with a mounting groove 112c which is spaced apart from the shaft hole 112a in the radial direction of the rotating shaft 12. Figure 5 As shown in the figure, the rotating shaft assembly 10 further includes a first gasket 14. Figure 6As shown, the first washer 14 includes a first axial body 141 and a first radial body 142 connected with each other. The first axial body 141 is sleeved on the shaft 12 and abuts against the lug 112; the first radial body 142 is embedded in the mounting groove 112c and abuts against the lug 112. When it is necessary to adjust the pitch angle of the display 1, a torque is generated by operating the display 1 to overcome the engagement force of the limiting tooth C with the first engagement tooth A and the second engagement tooth B, so that the shaft 12 rotates relative to the sleeve 13; when the shaft 12 rotates, the first axial body 141 is sleeved on the shaft 12 and abuts against the lug 112, and the first radial body 142 is embedded in the mounting groove 112c and abuts against the lug 112, so that the support plate 111 is driven to rotate together, and the display 1 can be driven to rotate.

[0055] Generally speaking, Figure 6 As shown, the first axial body 141 is provided with a circular through hole 141a for sleeving the shaft 12. In some embodiments, the first axial body 141 can also be provided with a non-circular through hole 141a for sleeving the shaft 12.

[0056] Optionally, Figure 5 As shown, the shaft assembly 10 further includes a second washer 15. Figure 7 As shown, the second washer 15 has a non-circular through hole 151a, so that the second washer 15 is sleeved on the shaft 12; the second washer 15 includes first and second abutting surfaces arranged opposite in the axial direction of the shaft 12; the first abutting surface abuts against the sleeve 13, and the second abutting surface abuts against the first washer 14. The second washer 15 is abutted on the first washer 14 by the sleeve 13. When the shaft 12 rotates, the second washer 15 rotates with the shaft 12 due to the non-circular through hole 151a of the second washer 15, and then the second washer 15 generates a friction torque with the first washer 14 to drive the first washer 14 to rotate, and then the support plate 111 is driven to rotate due to the first radial body 142 being embedded in the mounting groove 112c and abutting against the lug 112.

[0057] Specifically, Figure 5 As shown, the second washer 15 includes a second axial body 151 and a second radial body 152 connected with each other. The non-circular through hole 151a is arranged on the second axial body 151 to sleeve the shaft 12. The second axial body 151 abuts against the first axial body 141 and the sleeve 13, respectively. The second radial body 152 can abut against the first radial body 142.

[0058] Optionally, Figure 5As shown, the rotating shaft assembly 10 further comprises a third gasket 16 and a locking nut 17; the locking nut is threadedly connected with the rotating shaft 12; the third gasket 16 is sleeved on the rotating shaft 12, and comprises a third abutting surface and a fourth abutting surface oppositely arranged in the axial direction of the rotating shaft 12, the third abutting surface abuts against the first gasket 14, and the fourth abutting surface abuts against the locking nut. The third gasket 16 is abutted against the first gasket 14 by the locking nut 17, so that the first gasket 14 and the lug 112 can generate sufficient normal pressure, and in turn, the first gasket 14 and the lug 112 can generate sufficient friction when the rotating shaft 12 rotates, so that the support 11 can rotate with the rotating shaft 12.

[0059] As an optional implementation of the above embodiment, Figure 8 As shown, the support plate 111 is provided with a limiting through hole 111a formed in the thickness direction thereof. In the specific implementation process, the housing 20 is provided with a limiting block 22. When the support plate 111 is installed on the housing 20, the limiting block 22 can limit the upward, downward, leftward and rightward movement of the support plate 111.

[0060] As an optional implementation of the above embodiment, the support 11 further comprises a limiting plate 113 arranged at the side edge of the support plate 111. In the specific implementation process, the housing 20 is provided with a limiting groove. When the support plate 111 is installed on the housing 20, the limiting plate 113 is embedded in the limiting groove to limit the forward and backward movement of the support plate 111.

[0061] In the specific implementation process, Figure 11As shown, the shell 20 comprises a first shell segment 21, a second shell segment 23 and a third shell segment 24. The second shell segment 23 and the first shell segment 21 are spaced apart in the thickness direction of the support plate 111, and are connected by the third shell segment 24, the first shell segment 21, the second shell segment 23 and the third shell segment 24 enclose the mounting port 20a. The rotating shaft assembly 10 is mounted in the mounting port 20a. The side plate 25 is connected with the second shell segment 23 and the third shell segment 24. The side plate 25 is formed with a first limiting groove 20b, and the third shell segment 24 is formed with a second limiting groove 20c. One limiting plate 113 of the support plate 111 is embedded in the corresponding first limiting groove 20b, and the other limiting plate 113 is embedded in the corresponding second limiting groove 20c. The limiting through hole 111a of the support plate 111 is clamped on the limiting block 22 of the support plate 111, and the installation of the rotating shaft assembly 10 is completed. The shell 20 comprises a quick release button plate 26. The quick release button plate 26 is connected with the second shell segment 23, and the limiting block 22 is arranged on the quick release button plate 26. When it is needed to release the limiting effect of the limiting block 22 on the support plate 111, the quick release button plate 26 is pressed, so that the limiting block 22 moves. The quick release button plate 26 has good elasticity, and comprises a first extension segment, a second extension segment and a third extension segment connected in sequence. The first extension segment is connected with the second shell segment 23 and is accommodated in the accommodating port of the second shell segment 23. The limiting block 22 is arranged on the first extension segment and protrudes from the surface of the second shell segment 23. The second extension segment is accommodated in the accommodating port of the third shell segment 24. The third extension segment is accommodated in the accommodating port of the first shell 20. The button is arranged on the third extension segment.

After the rotating shaft assembly 10 is mounted in the mounting port 20a, the buckle of the cover plate 40 is mounted in the clamping groove 20d of the second shell segment 23, and then the rotating shaft assembly 10 is hidden in the shell 20. The cover plate 40 is provided with a through hole for the support 30 to extend into the mounting port 20a to be connected with the support 132 of the sleeve 13.

Since the rotating shaft assembly 10 adopts a part or all of the foregoing embodiment, the display 1 has some or all of the technical advantages of the foregoing embodiment, which will not be described one by one.
