The spindle module provided by the embodiment of the present application can be applied to a rotatable device having two objects capable of rotating relatively, and is used as a rotating mechanism for rotating the two objects relative to each other. The rotatable electronic device may be, but is not limited to, an electronic device or a mechanical device. Taking the electronic device as an example, the first object of the two objects may be a device base, and the second object may be a display screen, so that the second object is driven by the rotating shaft module to turn over relative to the first object to change the viewing angle. It should be understood that the above is illustrative, and not restrictive in practical applications.

Referring to fig. 1 to 5, an embodiment of the present application provides a spindle module 1, which includes a first sleeve 10, a second sleeve 20, and a shaft assembly 30. The first sleeve 10 and the second sleeve 20 may be, but are not limited to, hollow cylindrical sleeves. Wherein the first sleeve 10 has a first end 110 and a second end 120 opposite to each other, and one or more first sliding rails 130 may be, but are not limited to, disposed on the sidewall of the first sleeve 10. The first slide rail 130 penetrates from the inner wall surface to the outer wall surface of the first sleeve 10, and extends along the second end 120 toward the first end 110, so as to form a strip-shaped hollow structure on the side wall of the first sleeve 10. In the present embodiment, the first slide rails 130 are disposed on two opposite sidewalls of the first sleeve 10, respectively, for illustration, but not limited thereto. Therefore, in the embodiment, the 2 first slide rails 130 are disposed oppositely based on the axis of the first sleeve 10, so that the 2 first slide rails 130 are respectively located at two opposite sides of the first sleeve 10, however, the number and the positions of the first slide rails 130 can be adjusted according to different design requirements, and the application is not limited thereto.

Wherein each first sliding rail 130 is disposed toward the axial direction of the first sleeve 10, for example, the first sliding rail 130 may extend from a starting point 131 adjacent to the first end 110 to a terminal point 132 adjacent to the second end 120 substantially toward the axial direction of the first sleeve 10. Also, the first slide rail 130 may be, but not limited to, rotated on the sidewall of the first sleeve 10 by an angle, and disposed in a spiral track, for example, the terminal point of the first slide rail is rotated along the circumference while extending relative to the starting point, so that the starting point 131 and the terminal point 132 of the first slide rail 130 have an included angle of 30-60 degrees, for example, an included angle of about 45 degrees, 50 degrees or 55 degrees.

The second sleeve 20 is sleeved outside the first sleeve 10. One end of the second sleeve 20 is a closed end 220, and the other end is an open end 210 with an opening, through which the first sleeve 10 passes from the open end 210 of the second sleeve 20 to be disposed in the second sleeve 20. At this time, the first sleeve 10 and the second sleeve 20 are coaxially disposed and stopped by the closed end 220 of the second sleeve 20 to be received in the second sleeve 20. The side wall of the second sleeve 20 is provided with at least one second sliding rail 230, which may be a strip-shaped hollow structure extending along the direction from the open end 210 to the closed end 220 and penetrating from the inner wall surface of the side wall to the outer wall surface, or a strip-shaped groove disposed on the inner wall surface of the second sleeve 20 without penetrating to the outer wall surface.

Similar to the first sleeve 10, the second slide rail 230 may also be provided in one or more forms on the second sleeve 20. In the embodiment of the present application, 2 second sliding rails 230 are disposed on two opposite sidewalls of the second sleeve 20, respectively, for illustration and not limitation. The 2 second slide rails 230 are oppositely disposed based on the axis of the second sleeve 20, so that the 2 second slide rails 230 are respectively disposed on two opposite sidewalls of the second sleeve 20. Moreover, when the first sleeve 10 and the second sleeve 20 are fitted with each other, the position of the second slide rail 230 corresponds to the position of the first slide rail 130, so the number and the position of the second slide rail 230 can be adjusted according to different requirements, for example, the number and the position of the first slide rail 130, which is not limited to the embodiment.

Further, in the embodiment of the present application, each of the second sliding rails 230 is disposed toward the axial direction of the second sleeve 20, for example, the second sliding rails 230 may extend from a starting point 231 adjacent to the open end 210 to an ending point 232 adjacent to the closed end 220 substantially toward the axial direction of the second sleeve 20. The second sliding rail 230 may be, but is not limited to, arranged in a spiral track on the sidewall of the second sleeve 20. For example, the start point 231 and the end point 232 of the second slide rail 230 have an included angle of 30-60 degrees, for example, in the present embodiment, the included angle between the start point 231 and the end point 232 of the second slide rail 230 is about 45 degrees, 50 degrees, or 55 degrees, etc.

Although the first slide rail 130 and the second slide rail 230 are illustrated as spiral rails in the above embodiments, in some embodiments of the present disclosure, one of the first slide rail 130 and the second slide rail 230 may be a spiral rail and the other is a linear rail. The purpose of mutual rotation is achieved through the characteristic that the two slide rails are crossed and at least one of the two slide rails rotates for an angle.

It should be noted that, in the embodiment of the present application, the rotation angles of the second slide rail 230 and the first slide rail 130 are opposite, so that when the second sleeve 20 is sleeved on the first sleeve 10, the second slide rail 230 overlaps the first slide rail 130 in the radial direction of the first sleeve 10 and the radial direction of the second sleeve 20, and intersects the first slide rail 130 in the axial direction, and the intersection point between the two can be reciprocally displaced along the axial direction along with the relative rotation of the first sleeve 10 and the second sleeve 20. In addition, on the sleeve joint of the second sleeve 20 and the first sleeve 10, the outer diameter of the first sleeve 10 is not larger than the inner diameter of the second sleeve 20, so that when the second sleeve 20 is sleeved on the first sleeve 10, the outer peripheral surface of the first sleeve 10 can be close to or in contact with the inner peripheral surface of the second sleeve 20. Thus, a structural interference fit is created between the first sleeve 10 and the second sleeve 20, and they are rotatable relative to each other.

The shaft assembly 30 includes a bar body 310 and a slider 320, which are respectively disposed in the first sleeve 10, and the slider 320 is sleeved on the bar body 310, so that the slider 320 can be displaced on the bar body 310 along the axial direction of the first sleeve 10 relative to the bar body 310. The slider 320 is provided with a shaft hole 321 and a linkage portion 322, the lever body 310 passes through the shaft hole 321 of the slider 320, so that the slider 320 is sleeved on the lever body 310, wherein the outer circumferential surface of the lever body 310 and the inner circumferential surface of the shaft hole can be provided with a matched screw structure, for example, the lever body 310 can be but not limited to a screw rod, so that a male thread is provided on the outer circumferential surface of the lever body 310, and a matched female thread is provided in the shaft hole 321 of the slider 320, so that the slider 320 can be driven to displace in the first sleeve 10 by the mutual matching of the screw structures when the lever body 310 rotates. Conversely, the slider 320 may be rotated on the lever 310 to displace the lever 310 in the first sleeve 10. The linking portion 322 protrudes from the surface of the sliding member 320, and can sequentially extend into the corresponding first sliding rail 130 and the second sliding rail 230 along the radial direction of the sliding member 320 corresponding to the position where the first sliding rail 130 and the second sliding rail 230 are staggered with each other.

In the embodiment of the present application, the slider 320 has 2 interlocking parts 322. The 2 linkage portions 322 are respectively disposed on opposite sides of the slider 320 with the shaft hole 321 as a center. In addition, the arrangement position and number of the linking parts 322 can be adjusted correspondingly with the positions and numbers of the first slide rail 130 and the second slide rail 230, that is, one linking part 322 corresponds to one first slide rail 130 and one second slide rail 230 stacked with each other, so that each linking part 322 can sequentially extend into the corresponding first slide rail 130 and second slide rail 230.

Meanwhile, in some embodiments of the present application, the linkage portion 322 has a first guide block 3221 and a second guide block 3222, which have different directions. Here, the first guide block 3221 and the second guide block 3222 are stacked in a projection direction, that is, in a radial direction of the slider, and due to the different directions, the first guide block 3221 and the second guide block 3222 are structurally inclined to each other, that is, if an inclination angle of the first guide block 3221 matches a rotation angle of the first slide rail 130, an inclination angle of the second guide block 3222 matches a rotation angle of the second slide rail 230, and intersects with the inclination angle of the first guide block 3221. Therefore, when the linking portion 322 sequentially extends into the first slide rail 130 and the second slide rail 230 on the same side, the first guiding block 3221 is movably disposed in the first slide rail 130, and the second guiding block 3222 is movably disposed in the second slide rail 230. When the sliding member 320 is displaced relative to the lever body 310, the first guide block 3221 of the linking portion 322 moves along the first slide rail 130 and pushes the first sleeve 10 to rotate, and the second guide block 3222 of the linking portion 322 moves along the second slide rail 230 and pushes the second sleeve 20 to rotate, so that the first sleeve 10 and the second sleeve 20 rotate in opposite directions.

In addition, in the configuration of the shaft assembly 30, through holes 140 may be respectively disposed on the end surface of the first end 110 and the end surface of the second end 120 of the first sleeve 10, so that the opposite ends of the bar body 310 of the shaft assembly 30 can be inserted into the corresponding through holes 140, and when the slider 320 is sleeved on the bar body 310, the outer diameter of the portion of the slider 320 excluding the interlocking portion 322 is not greater than the inner diameter of the first sleeve 10, that is, equal to or slightly smaller than the inner diameter of the first sleeve 10, so that the outer peripheral surface of the portion is close to or in contact with the inner peripheral surface of the first sleeve 10. Therefore, a structural interference effect is generated between the first sleeve 10 and the slider 320, and the frictional force generated between the first sleeve 10 and the slider 320 can be increased in addition to allowing the slider 320 to be stably linearly displaced within the first sleeve 10.

In operation, the shaft assembly can be operated manually by a user to rotate the sliding member or the lever, or in some embodiments of the present application, the rotating shaft module 1 further includes a motor 40 connected to the lever 310, wherein the motor 40 is connected to the axial center of the lever 310 to provide power to rotate the lever 310 and displace the sliding member 320 in the first sleeve 10. In this embodiment, the first sleeve 10 is provided with a movable space 101 and a receiving space 102. The movable space 101 corresponds to the first end 110 of the first sleeve 10, the accommodating space 102 corresponds to the second end 120 of the first sleeve 10, and a spacer 103 is disposed between the movable space 101 and the accommodating space 102. The opposite ends of the lever 310 of the shaft assembly 30 are respectively inserted into the end face of the first end 110 of the first sleeve 10 and the spacing portion 103, the sliding member 320 is movably disposed in the moving space 101, and the motor 40 is disposed in the accommodating space 102, so that the rotating shaft module 1 has the characteristics of compact structure and small volume. It is understood that, in some embodiments of the present application, the outer diameter of the motor 40 and the inner diameter of the first sleeve 10 are matched to each other, so that the outer circumferential surface of the motor 40 abuts against the inner circumferential surface of the first sleeve 10 to fix the motor, and the arrangement of the partition 103 in the first sleeve 10 may be omitted.

The following further describes embodiments of the present application through application scenarios.

Referring to fig. 6 and 7, the hinge module 1 of the present application can be applied to a rotatable device a having two relatively rotatable objects, and the rotatable device a can be any electronic device or mechanical device. As shown in fig. 7 and 8, the hinge module 1 of the present application enables the first object A1 of the rotatable device a to be pivotally connected to the second object A2, for example, an electronic device, the first object A1 may be a display screen, and the second object A2 may be a device base, but the present application is not limited thereto.

As shown in fig. 1 to 7, when the user wants to turn the first object A1 relative to the second object A2 to adjust the setting angle of the first object A1, an operation command may be first input through the operation keys of the rotatable device a to notify the motor 40 of the actuation, or directly through manual operation (in such an embodiment, the configuration of the motor 40 may be omitted). When the motor 40 starts to operate, the lever body 310 of the driving shaft assembly 30 starts to rotate. Because the shaft assembly 30 has the screw structure matching with the recess of the lever 310 and the slider 320, the slider 320 can be driven to rotate and displace relative to the lever 310 when the lever 310 rotates.

Meanwhile, during the displacement of the sliding member 320 relative to the lever body 310, the linkage portion 322 is driven to displace in the first sliding rail 130 and the second sliding rail 230, so that the first guiding block 3221 of the linkage portion 322 pushes the first sleeve 10 to rotate clockwise or counterclockwise, and the second guiding block 3222 of the linkage portion 322 pushes the second sleeve 20 to rotate in the direction opposite to the above direction. Due to the opposite rotation of the first sleeve 10 and the second sleeve 20, the first article A1 is finally turned over with respect to the second article A2.

In the embodiment of the present application, the hinge module 1 further includes a connecting member 50 having one side pivotally connected to the lever body 310 and the other side connected to the first object A1. Therefore, when the sliding member 320 pushes the first sleeve 10 and the second sleeve 20 to rotate, the connecting member 50 is also driven to push the first article A1 to turn relative to the second article A2.

Referring to fig. 2 and 3 and fig. 8 to 10, in the embodiment of the present application, it is assumed that both the helical groove lead of the first slide rail 130 and the helical groove lead of the second slide rail 230 (i.e., the displacement strokes provided by the first slide rail 130 and the second slide rail 230) are L, and taking the second slide rail 230 as an example, when the extension length el of the second slide rail 230 based on the axial direction of the second sleeve 20 is 80mm, and the included angle θ between the start point 231 and the end point 232 of the second slide rail 230 is 45 degrees, the helical groove lead L of the second slide rail 230 is 80 × 360/45=640mm. Further, assuming that the lead of the lever 310 is X, it is defined as the displacement of the slider 320 relative to the lever 310 after one rotation of the lever 310. The rotation speed N of the motor 40 can be obtained as the output rotation speed N of the rotating shaft module 1, which can be expressed by the following equation (1):

n =2 x/L equation (1)

In the embodiment and the drawings of the present application, it can be known that the helical groove lead L of the second slide rail 230 is far greater than the lead X of the bar body 310, and therefore the output rotation speed N of the rotating shaft module 1 is far less than the rotation speed N of the motor 40.

Further, assuming that the transmission efficiency of the rotating shaft module 1 is U, the output torque of the motor 40 is M, and therefore the output torque M of the rotating shaft module 1 can be expressed by the following equation (2):

m = M L U/X equation (2)

Since the lead L of the second slide rail 230 is much greater than the lead X of the bar body 310, the output torque M of the rotating shaft module 1 of the embodiment of the present application is much greater than the output torque M of the motor 40.

Therefore, if the shaft module 1 of the embodiment of the present application uses the lever 310 with a small pitch, the slider 320 is not easily displaced left and right under the action of external force, and the self-locking effect of the position of the slider 320 is further achieved. Furthermore, under the effect of the friction force generated by the close-fitting of the structure between the sliding member 320, the first sleeve 10 and the second sleeve 20, the hinge module 1 cannot be easily rotated by external force, so that the hinge module 1 can achieve the self-locking effect of the rotation angle.

In the embodiment of the present application, the sliding member 320 of the shaft assembly 30 of the spindle module 1 is driven by the lever body 310 to generate displacement, so as to synchronously push the first sleeve 10 and the second sleeve 20 to rotate with each other, and the overall structure of the spindle module 1 is cylindrical, so that the spindle module 1 can achieve a larger reduction ratio and a larger transmission torque within a smaller structural size, thereby replacing the mutual engagement transmission of the conventional gear assemblies. In addition, in the embodiment of the present application, under the action of the friction force between the first sleeve 10, the second sleeve 20 and the sliding member 320 of the rotating shaft module 1, the rotating shaft module 1 can generate a rotation self-locking effect in a standing state, and the rotating shaft module 1 can also avoid forming passive rotation when being influenced by an external force.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement or the like made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
