Fig. 19 is a schematic diagram illustrating damping feedback during rotation of the spindle device 100 according to an embodiment of the present application.

As shown in fig. 3 to 18, in the rotating shaft device 100 according to an embodiment of the present application, the rotating shaft device 100 includes a rotating shaft 110 and a sleeve 120, wherein the sleeve 120 is sleeved on the rotating shaft 110, one of the rotating shaft 110 and the sleeve 120 is provided with a damping slot set, the other is provided with a damping portion 140, the damping slot set includes a plurality of damping slots 130, the damping portion 140 and the damping slots 130 are oppositely arranged and are in interference fit, and when the rotating shaft 110 and the sleeve 120 rotate relatively, the damping portion 140 sequentially moves into or out of the plurality of damping slots 130.

In the embodiment of the present application, the rotating shaft device 100 includes a rotating shaft 110 and a sleeve 120, where the rotating shaft 110 and the sleeve 120 can rotate relatively, it can be understood that the rotating shaft 110 can rotate alone, the sleeve 120 can rotate alone, and in addition, both the rotating shaft 110 and the sleeve 120 can rotate, which is specifically set according to actual needs. Further, the damping slot set includes a plurality of damping slots 130, and it can be understood that the plurality of damping slots is two or more damping slots. The damping slot group is arranged on one of the rotating shaft 110 and the sleeve 120, the damping part 140 is arranged on the other of the rotating shaft 110 and the sleeve 120, and the damping part 140 can move into or out of the damping slot 130 when the rotating shaft 110 and the sleeve 120 rotate relatively, so that different damping feelings can be fed back when the damping part 140 moves into or out of the damping slot 130.

Specifically, the plurality of damping grooves 130 are formed in the rotating shaft 110, the damping part 140 is formed in the sleeve 120, when the rotating shaft 110 and the sleeve 120 rotate relatively, the damping part 140 is driven by the sleeve 120 to rotate, and when the sleeve 120 does not move into the damping groove 130, the damping part 140 contacts with the outer circumferential surface of the rotating shaft 110, so that the damping part 140 generates a certain amount of compression, when the sleeve 120 drives the damping part 140 to gradually move into the damping groove 130, the amount of compression of the damping part 140 is gradually released, when the damping part 140 moves into the damping groove 130, the elastic force generated by the damping part 140 is minimum, the corresponding damping force is minimum, and thus the variable damping feeling during the relative rotation of the rotating shaft 110 and the sleeve 120 can be realized.

It can be understood that the rotating experience of various damping feelings, such as "variable damping feeling" or "equal damping feeling", can be realized by changing the distribution of the plurality of damping grooves 130 on the rotating shaft 110 or the sleeve 120 and the distribution of the plurality of damping portions 140 on the sleeve 120 or the rotating shaft 110.

In addition, the rotating shaft device 100 of the embodiment of the application has a simple structure and occupies a small space, and can avoid the problems of complex rotating structure, high manufacturing cost and large manufacturing difficulty caused by resistance generated by nesting of special-shaped teeth during rotation in the related art. When the rotating shaft device 100 is applied to electronic equipment such as a mobile phone and the like needing to rotate, the ultrathin refined design of the electronic equipment can be realized on the basis of realizing the rotating experience of different damping senses, so that the electronic equipment is high-end and high-quality, and the use experience of a user is further improved.

In a specific application, when the rotating shaft device 100 is applied to a foldable electronic device such as a mobile phone, the rotating shaft device 100 is respectively connected to two parts of shells of the electronic device, so that one part of the shells can be rotated relative to the other part of the shells through manually or automatically turning over the one part of the shells, thereby implementing a folding screen or a turning-over cover of the electronic device such as the mobile phone. In the process of turning, when the electronic equipment rotates to different positions, different damping feelings can be fed back, and the rotating experience is improved. In addition, the rotating shaft device 100 has a simple structure and a small occupied space, and can realize ultrathin and fine design of electronic equipment such as a mobile phone, and further improve the use experience of a user on the electronic equipment such as the mobile phone.

As shown in fig. 7 to 18, when the rotating shaft 110 and the sleeve 120 rotate relatively to different positions, the relative position relationship between the damping portion 140 and the damping slot 130, that is, the rotation state when the damping portion 140 moves into or out of the damping slot 130, is shown. Specifically, when fig. 9 to 11 show, the damping portion 140 is in contact with the outer side wall of the rotating shaft 110, and therefore, the compression of the damping portion 140 is not changed, and the feedback damping value is not changed. As shown in fig. 11 to 13, the sleeve 120 drives the damping portion 140 to gradually move into the damping slot 130, and the damping portion 140 with a certain compression amount gradually releases the compression amount, that is, the compression amount of the damping portion 140 decreases, and the feedback damping value gradually decreases. As shown in fig. 13 to 15, the sleeve 120 drives the damping portion 140 to move out of the damping slot 130 gradually, and in the process, the compression amount of the damping portion 140 increases gradually, the generated elastic force increases gradually, and the feedback damping value increases. In fig. 15 to 17, the damping portion 140 is always in contact with the outer side wall of the rotating shaft 110, and therefore, the compression of the damping portion 140 is not changed, and the feedback damping value is not changed. Thereby achieving a variable damping rotation experience during the relative rotation of the rotating shaft 110 and the sleeve 120.

As shown in fig. 19, the feedback of the damping value is shown when the rotating shaft device 100 rotates and the rotating shaft 110 and the sleeve 120 rotate relatively to different positions, and the change process of the damping value is clearly seen from the figure.

In a specific application, the number of the damping grooves 130 and the damping parts 140 can be set according to actual needs. Specifically, the number of the damping grooves 130 and the number of the damping portions 140 may be the same or different, for example, a plurality of damping grooves 130 and one damping portion 140 may be provided, so that a rotation experience of a variable damping feeling is realized in a process of relative rotation between the rotating shaft 110 and the sleeve 120. Further, one damping groove 130 and a plurality of damping portions 140 may be provided, but other numbers may be provided as long as a variable damping value during rotation can be achieved.

In some embodiments, as shown in fig. 3, 7, 9, 11, 13, 15, 17, 21, 22, 23, 24, 27, 28, 29, and 30, the plurality of damping grooves 130 are distributed on the outer wall surface of the rotating shaft 110 along the circumferential direction of the rotating shaft 110, or the plurality of damping grooves 130 are distributed on the inner wall surface of the sleeve 120 along the circumferential direction of the sleeve 120; wherein, a plurality of damping grooves 130 are symmetrically distributed along the central axis.

In these embodiments, the sleeve is sleeved outside the rotating shaft 110, so that the occupied space of the rotating shaft device 100 can be further reduced, and when the rotating shaft device 100 is applied to electronic equipment such as a mobile phone, the ultra-thin and fine design of the electronic equipment such as the mobile phone is easy to realize. Further, when the damping slot group includes a plurality of damping slots 130, that is, when the damping slot group includes two or more damping slots 130, the damping slots 130 are disposed on the outer wall surface of the rotating shaft 110 along the circumferential direction of the rotating shaft 110, and the damping slots 130 are symmetrically distributed along the central axis of the rotating shaft 110, or the damping slots 130 are disposed on the inner wall surface of the sleeve 120 along the circumferential direction of the sleeve 120, and the damping slots 130 are symmetrically distributed along the central axis of the sleeve 120, so that the rotating shaft 110 or the sleeve 120 can be uniformly stressed at each position in the circumferential direction, the service life of the rotating shaft 110 or the sleeve 120 is prolonged, and the service life of the rotating shaft device 100 can be prolonged.

In a specific application, since the sleeve is disposed outside the rotating shaft 110, the sleeve may coincide with the central axis of the rotating shaft 110. In addition, the central axis of the sleeve and the central axis of the rotating shaft 110 may not coincide, and the sleeve and the central axis may be specifically arranged according to actual needs.

In some embodiments, as shown in fig. 3, 7, 9, 11, 13, 15, 17, 21, 22, 23, 24, 27, 28, 29, and 30, when there are a plurality of damping portions 140, the plurality of damping portions 140 are distributed on the outer wall surface of the rotating shaft 110 along the circumferential direction of the rotating shaft 110, or the plurality of damping portions 140 are distributed on the inner wall surface of the sleeve 120 along the circumferential direction of the sleeve 120; wherein the plurality of damping portions 140 are symmetrically distributed along the central axis.

In these embodiments, the sleeve is sleeved outside the rotating shaft 110, so that the occupied space of the rotating shaft device 100 can be further reduced, and when the rotating shaft device 100 is applied to electronic equipment such as a mobile phone, the ultra-thin and fine design of the electronic equipment such as the mobile phone is easy to realize. Further, when the number of the damping portions 140 is plural, the damping portions 140 are disposed on the outer wall surface of the rotating shaft 110 along the circumferential direction of the rotating shaft 110, and the damping portions 140 are symmetrically distributed along the central axis of the rotating shaft 110, or the damping portions 140 are disposed on the inner wall surface of the sleeve 120 along the circumferential direction of the sleeve 120, and the damping portions 140 are symmetrically distributed along the central axis of the sleeve 120, so that the rotating shaft 110 or the sleeve 120 can be uniformly stressed at each position in the circumferential direction, the service life of the rotating shaft 110 or the sleeve 120 is prolonged, and the service life of the rotating shaft device 100 can be prolonged.

It can be understood that the damping portion 140 may be fixedly connected to the rotating shaft 110 or the sleeve 120, or may be integrally formed with the rotating shaft 110 or the sleeve 120, and may be specifically configured according to actual needs.

The damping portion 140 may be an elastic member, a friction plate, or the like.

Fig. 20 shows a second schematic structural view of the rotating shaft device 100 according to an embodiment of the present application, in which all the damping portions 140 and the damping grooves 130 are symmetrically distributed along the axial direction of the rotating shaft 110 or the sleeve 120.

Fig. 25 is a schematic diagram illustrating a second damping feedback condition during the rotation of the rotating shaft device 100 according to an embodiment of the present application.

In a specific embodiment, as shown in fig. 6, 20, 21, 22, 23 and 24, the number of the damping groove sets is plural, and the plural damping groove sets are distributed along the axial direction of the rotating shaft or the sleeve.

In this embodiment, the damping groove group is defined to be plural, the plural damping groove groups are distributed along the axial direction of the rotating shaft 110 or the sleeve 120, the corresponding damping portion 140 is also plural, and the plural damping portions 140 are arranged corresponding to the plural damping grooves 130 of the plural damping groove groups. So that the damping part 140 can move into or out of the damping groove 130 when the rotation shaft 110 and the sleeve 120 perform relative rotation, thereby being capable of feeding back different damping feelings during the movement of the damping part 140 into or out of the damping groove 130. By arranging the plurality of damping slot groups which are distributed along the axial direction of the rotating shaft 110 or the sleeve 120, different damping feelings can be fed back at a plurality of positions of the rotating shaft 110 or the sleeve 120 in the axial direction when the rotating shaft 110 and the sleeve 120 rotate relatively, and the rotating experience is improved.

In some embodiments, as shown in fig. 6, 20, 21, 22, 23 and 24, the plurality of damping slot sets includes a first damping slot set and a second damping slot set, wherein the second damping slot set and the first damping slot set are symmetrically distributed in the axial direction of the rotating shaft 110 or the sleeve 120; the damping portions 140 correspond to the damping grooves 130 one by one, and when the rotating shaft 110 and the sleeve 120 rotate relatively to any angle, each damping portion 140 of the plurality of damping portions 140 moves into or out of the damping groove 130 synchronously.

In these embodiments, an implementation of a variable damping feel rotational experience of the spindle assembly 100 is defined. Specifically, the plurality of damping slot groups include a first damping slot group and a second damping slot group, and it can be understood that the damping slots 130 symmetrically arranged along the central axis in the circumferential direction of the rotating shaft 110 or the sleeve 120 are a group of damping slot groups, wherein the first damping slot group and the second damping slot group are symmetrically distributed and arranged in relation to the axial direction of the rotating shaft 110 or the sleeve 120, and the damping portions 140 are in one-to-one correspondence with the damping slots 130, that is, the damping portions 140 are not only in one-to-one correspondence with the damping slots 130, but also in one-to-one correspondence with the damping slots 130. Further, when the rotating shaft 110 and the sleeve 120 rotate relatively to any angle, each damping portion 140 can move into or out of the damping slot 130 synchronously, that is, all damping portions 140 on the rotating shaft 110 or the sleeve 120 are in the same compression state, that is, the damping values fed back by all damping portions 140 are the same, that is, when the rotating shaft 110 and the sleeve 120 rotate relatively to any angle, the damping values fed back by all damping portions 140 are the same, so that the damping values fed back by all damping portions 140 change synchronously during the relative rotation of the rotating shaft 110 and the sleeve 120. Specifically, all the damping portions 140 are synchronously in contact with the rotating shaft 110 or the sleeve 120 and synchronously move into or out of the damping slot 130, so that the rotating experience of the variable damping feeling during the rotating process is realized.

In a specific application, the plurality of damping slot groups may further include a third damping slot group, a fourth damping slot group, and the like, as long as all damping slot groups are symmetrically distributed along the axial direction of the rotating shaft 110 or the sleeve 120, and in the rotating process, all damping portions 140 move synchronously, that is, all damping portions 140 are in the same compression state at any time, so that the rotating experience of the variable damping sense in the rotating process, that is, the rotating experience of the "staged damping sense" of the rotating shaft device 100, can be realized.

As shown in fig. 25, it shows the feedback situation of different damping values when the rotating shaft 110 and the sleeve 120 rotate relatively to different positions during the rotation of the rotating shaft device 100, and the change process of the damping value can be clearly seen from the figure.

In other embodiments, as shown in fig. 26, 27, 28, 29 and 30, the damping portions 140 correspond to the damping grooves 130 one by one, and when the rotating shaft 110 and the sleeve 120 rotate relatively to any angle, at least one damping portion 140 of the plurality of damping portions 140 moves into the damping groove 130, and at least one damping portion 140 of the plurality of damping portions 140 moves out of the damping groove 130.

In these embodiments, an implementation of a damped feel rotational experience is defined for the spindle assembly 100 or the like. Specifically, the damping portions 140 correspond to the damping grooves 130 one by one, that is, the damping portions 140 correspond to the damping grooves 130 not only in number but also in position. Further, when the rotating shaft 110 and the sleeve 120 rotate relatively to each other to any angle, at least one damping portion 140 of the plurality of damping portions 140 moves into the damping slot 130, and at least one damping portion 140 moves out of the damping slot 130, that is, when the rotating shaft 110 and the sleeve 120 rotate to any time, at least two damping portions 140 can feed back different damping values.

It can be understood that, when any damping slot group in the plurality of damping slot groups includes the plurality of damping slots 130, that is, the number of the damping slots 130 and the damping portions 140 is sufficiently large, when the rotating shaft 110 and the sleeve 120 rotate to any time, all the damping portions 140 are in different compression states, that is, the damping values fed back by all the damping portions 140 at any time in the rotating process are different, so that when the rotating shaft rotates to any time, the fluctuation of the total damping value gradually approaches zero, that is, at any time, the total damping value fed back is unchanged, thereby achieving the equal-damping rotating experience.

As shown in fig. 31, the feedback of the damping value is shown when the rotating shaft 110 and the sleeve 120 rotate relatively to different positions during the rotation of the damping sensor such as the rotating shaft device 100, and it is obvious from the figure that the total damping value fed back does not change when the rotating shaft rotates to any angle.

In some embodiments, as shown in fig. 3-30, the shaft 110 projects away from the central axis to form the damper 140, or a portion of the sleeve 120 projects toward the central axis to form the damper 140.

In these embodiments, it is defined that the rotating shaft 110 protrudes away from the central axis to form the damping portion 140, that is, when the damping portion 140 is disposed on the rotating shaft 110, the damping portion 140 protrudes from a portion of the rotating shaft 110, that is, the damping portion 140 and the rotating shaft 110 are an integral structure. Or a portion of the sleeve 120 protrudes toward the central axis to form the damping portion 140, that is, when the damping portion 140 is disposed on the sleeve 120, the damping portion 140 is formed by protruding a portion of the sleeve 120, that is, the damping portion 140 and the sleeve 120 are an integral structure. The integrated structure has good mechanical properties, and can ensure the connection strength between the damping part 140 and the rotating shaft 110 or the sleeve 120, so as to prolong the service life of the rotating shaft device 100, and in addition, can ensure the stability and reliability of the rotating process of the rotating shaft device 100.

In one particular embodiment, the sleeve 120 includes a body and a mounting port, wherein the mounting port is disposed on the body and the damping portion 140 is coupled to the body and positioned at the mounting port.

In this embodiment, the sleeve 120 is defined to include a body and a mounting opening, specifically, the mounting opening is provided on the body, and the damping portion 140 is provided at the mounting opening and at least partially protrudes, that is, the damping portion 140 protrudes to a side where the damping slot 130 is located, so as to achieve the matching with the damping slot 130.

In specific application, the damping portion 140 is installed to the installation opening, and the damping portion 140 and the body can be fixedly connected in a bonding manner, and also can be fixedly connected by rivets and the like, so that the stability of the damping portion 140 is ensured, and the reliability of the rotating process of the rotating shaft device 100 is further ensured.

In a particular embodiment, the slot opening area of the damping slot 130 is greater than the slot floor area of the damping slot 130.

In this embodiment, the notch area of the damping slot 130 is larger than the slot area of the damping slot 130, that is, the damping slot 130 is set to be a flaring structure, so that the smoothness of the rotation process of the rotating shaft 110 and the sleeve 120 can be further improved, and the use experience of the user can be further improved. In addition, the groove side wall of the damping groove 130 may be set to have a certain inclination angle, so that when the damping portion 140 moves into or out of the damping groove 130, the compression amount of the damping portion 140 may be gradually released or gradually compressed, thereby further improving the rotation experience of the rotating shaft device 100.

In another specific embodiment, the connection between the damping groove 130 and the shaft 110 or the sleeve 120 is rounded.

In this embodiment, a smooth transition is defined at the connection of the damping groove 130 and the rotation shaft 110 or the sleeve 120. Specifically, the notch of the damping groove 130 is connected to the outer sidewall of the rotating shaft 110 or the sleeve 120, and the connection is smooth, so that the smoothness of the rotating process of the rotating shaft 110 and the sleeve 120 can be further improved, and the user experience can be further improved.

In some embodiments, as shown in fig. 3, the rotating shaft device 100 further includes a bearing 150, the bearing 150 is disposed at an end of the rotating shaft 110, and an outer sidewall of the bearing 150 contacts an inner sidewall of the sleeve 120.

In these embodiments, it is defined that the rotating shaft device 100 further includes a bearing 150, and an outer sidewall of the bearing 150 contacts an inner sidewall of the sleeve 120, that is, the sleeve 120 is rotatably connected to the rotating shaft 110 through the bearing 150. Therefore, the bearing 150 can provide effective support in the relative rotation process of the rotating shaft 110 and the sleeve 120, and the smoothness of the rotation between the rotating shaft 110 and the sleeve 120 can be further ensured. And the bearing 150 is arranged to support the rotating shaft 110 and the sleeve 120, so that the abrasion problem between the rotating shaft 110 and the sleeve 120 in the rotating process can be effectively prevented, and the service life of the rotating shaft device 100 is further prolonged.

In a specific application, the bearing 150 is disposed at an end of the rotating shaft 110, so that a disposition space can be provided for the damping groove 130 or the damping portion 140, and the problem of reduced rotation experience caused by interference between the bearing 150 disposed in the middle of the rotating shaft 110 and the damping groove 130 or the damping portion 140 can be prevented.

In some embodiments, as shown in fig. 3, the rotating shaft device 100 further includes a bearing mounting portion 160, the bearing mounting portion 160 is disposed at two ends of the rotating shaft 110, and the bearing 150 is sleeved on the bearing mounting portion 160.

In these embodiments, the rotating shaft device 100 further includes bearing mounting portions 160, and specifically, the bearing mounting portions 160 are provided at both ends of the rotating shaft 110 for the bearings 150. It can be understood that the bearing 150 is sleeved on the bearing mounting portion 160, and after the sleeve 120 is sleeved on the rotating shaft 110, the inner wall surface of the sleeve 120 can contact with the outer surface of the bearing 150. That is, the sleeve 120 is rotatably coupled to the rotation shaft 110 by the bearing 150. In addition, the bearing mounting portion 160 may be integrally formed with the rotation shaft 110. The integrated structure has good mechanical property. The coupling strength between the bearing mounting part 160 and the rotation shaft 110 can be ensured, and the service life of the rotation shaft device 100 can be prolonged.

In a particular embodiment, the damping portion 140 includes an elastic member.

In these embodiments, the damping portion 140 is defined to include an elastic member, and specifically, the elastic member has a certain elasticity, so that when the elastic member moves into or out of the damping slot 130, a process of changing a compression amount of the elastic member can be realized, and thus a rotation experience of "staged damping feeling" or "equal damping feeling" in the rotation process of the rotating shaft device 100 can be realized.
