[0021] Please refer to Figure 1 to Figure 2 The embodiment of the present application discloses a rotation support device, which includes a base 100, a rotating part 200, a bearing 300 and a limiting part 400.

[0022] The base 100 is a basic component of the rotation support device. The base 100 is used to provide a mounting base for other components of the rotation support device. Of course, the base 100 can also form some functional spaces or structures. In the embodiment of the present application, the rotating part 200 is supported on the base 100, so that the base 100 can provide a mounting base for the rotating part 200.

[0023] The rotating part 200 is a core component for realizing the rotation in the supporting device, and the bearing 300 is a core component for realizing the rotation connection between the rotating part 200 and the base 100. The bearing 300 is respectively connected to the base 100 and the rotating part 200, so that the rotating part 200 can rotate relative to the base 100, that is, the rotating part 200 is rotationally connected to the base 100 through the bearing 300, so that the rotating part 200 can rotate relative to the base 100. The rotation axis of the rotating part 200 can coincide with the central axis of the bearing 300.

[0024] The limiting part 400 is a core component for limiting the position of the rotating part 200. The base 100 or the rotating part 200 is provided with a first track 210, which is an annular track extending around the rotation axis of the rotating part 200. The limiting part 400 is provided between the base 100 and the rotating part 200, and is guided and matched with the first track 210 in the direction around the rotation axis, so that when the rotating part 200 rotates relative to the base 100, the limiting part 400 can move along the first track 210. The limiting part 400 and the first track 210 are matched in the radial limiting position of the bearing 300, so that the rotating part 200 and the base 100 are matched in the radial limiting position, and the radial movement of the rotating part 200 relative to the base 100 in the bearing 300 is avoided during the rotation process.

[0025] In a specific working process, when the rotating part 200 rotates relative to the base 100, the limiting part 400 moves along the first track 210. At the same time, since the limiting part 400 and the first track 210 are radially limited in the bearing 300, and the limiting part 400 is arranged between the base 100 and the rotating part 200, the rotating part 200 and the base 100 can be radially limited, thereby avoiding the radial movement of the rotating part 200 relative to the base 100 in the bearing 300 during the rotation process, so that the rotating part 200 can rotate stably.

[0026] Optionally, the first track 210 may be an annular convex track or an annular track groove, and the embodiment of the present application does not limit the specific structure of the first track 210. Based on this, in one embodiment, the first track 210 is an annular convex track. In this case, the limiting portion 400 may have a limiting groove, so that the limiting portion 400 can be radially limited with the first track 210 through the limiting groove, so that the rotating portion 200 and the base 100 are radially limited. The limiting groove and the first track 210 can be guided and matched in a sliding manner in the direction around the rotation axis, and the limiting groove can contact the side walls of the first track 210 on both sides of the extension direction to achieve the radial limiting cooperation between the limiting portion 400 and the first track 210, so that the rotating portion 200 and the base 100 are radially limited.

[0027] Specifically, when the first track 210 is provided on the rotating part 200, the limiting part 400 can be fixedly connected to the base 100, and the first track 210 can be matched with the limiting part 400 through the limiting groove as the rotating part 200 rotates. Of course, when the first track 210 is provided on the base 100, the limiting part 400 can be fixedly connected to the rotating part 200, and the limiting part 400 can be matched with the first track 210 through the limiting groove as the rotating part 200 rotates.

[0028] In another embodiment, the first track 210 is an annular track groove. In this case, the limiting portion 400 can be partially embedded in the first track 210. Specifically, the limiting portion 400 can be a rolling body, annular protrusion or arc-shaped protrusion described later. The embodiment of the present application does not limit the specific structure of the limiting portion 400.

[0029] The rotation support device disclosed in the embodiment of the present application improves the structure of the rotation support device involved in the related art, by providing a limit portion 400, by providing a first track 210 on the base 100 or the rotating part 200, and setting the first track 210 as an annular track extending around the rotation axis, and by providing the limit portion 400 between the base 100 and the rotating part 200, and making the limit portion 400 and the first track 210 cooperate in the radial limit of the bearing 300, so that the rotating part 200 and the base 100 can cooperate in the radial limit of the bearing 300, avoiding the radial movement of the rotating part 200 relative to the base 100 in the bearing 300 during rotation, so that the rotating part 200 can rotate stably, and then the rotation support device can operate stably.

[0030] In the embodiment disclosed in the present application, the bearing 300 can be arranged on the base 100, and the bearing 300 can include a bearing inner ring and a bearing outer ring, the bearing inner ring and the bearing outer ring can be rotatably connected, the base can be fixedly connected to the bearing outer ring, and the rotating part can be fixedly connected to the bearing inner ring. This structure can stably fix the bearing 300 on the base 100, thereby facilitating the stable rotation of the rotating part 200, and further improving the stability of the rotating support device.

[0031] In one technical solution, there can be multiple bearings 300, and multiple bearings 300 can be stacked on the base 100 and can all be connected to the base 100. The rotating part 200 can be connected to multiple bearings 300, so that the rotating part 200 can be rotatably connected to the base 100 through the multiple bearings 300. The multiple bearings 300 are mutually constrained to alleviate the radial movement of the rotating part 200 relative to the base 100 on the bearings 300 during rotation, which is beneficial to improve the rotation stability of the rotating part 200, thereby improving the stability of the operation of the rotating support device.

[0032] In a further technical solution, the limiting part 400 may be a rolling body, the base 100 may be provided with a second track, the rotating part 200 may be provided with a first track 210, and both the first track 210 and the second track may be annular track grooves along the rotation axis, so that the rolling body can be installed between the first track 210 and the second track. There may be multiple rolling bodies, and they may respectively roll with the first track 210 and the second track in the direction around the rotation axis, so that there is rolling friction between the rolling body and the first track 210 and the second track, which is conducive to reducing the wear on the rolling body, thereby extending the service life of the rolling body. Specifically, the rolling body may be a ball or a needle, and the embodiment of the present application does not limit the specific structure of the rolling body.

[0033] At the same time, the rolling body can respectively cooperate with the first track 210 and the second track in radial limiting, so that the rotating part 200 can cooperate with the base 100 in radial limiting through the rolling body to prevent the rotating part 200 from moving relative to the base 100 in the radial direction during the rotation, so that the rotating part 200 can rotate stably. Specifically, the rolling body can respectively contact the side walls distributed on both sides of the first track 210 in the extension direction to achieve the radial limiting cooperation between the rolling body and the first track 210, and the rolling body can respectively contact the side walls on both sides of the second track in the extension direction to achieve the radial limiting cooperation between the rolling body and the second track.

[0034] In addition, in this structure, the rotating part 200 can cooperate with the base 100 through multiple rolling bodies, so that in the event of failure of some rolling bodies, the remaining rolling bodies can still roll with the first track 210 and the second track respectively in the direction around the rotation axis, so that the rotating part 200 can rotate normally relative to the base 100, and the remaining rolling bodies can still cooperate with the first track 210 and the second track respectively in radial limiting, so as to ensure the radial limiting cooperation between the rotating part 200 and the base 100, thereby ensuring the stability of the rotation of the rotating part 200.

[0035] Furthermore, the first track 210 may have a first accommodation depth for accommodating the rolling body described below, and the second track may have a third accommodation depth for accommodating the rolling body, and the third accommodation depth may be greater than the first accommodation depth. This structure allows most of the structure of the rolling body to be located in the second track to reduce the risk of the rolling body falling off the second track, and the second track is provided on the base 100, which is more stable relative to the rotating part 2000, so that the installation of the rolling body is more reliable, which is conducive to improving the reliability of the rotating support device and facilitating the installation of the rolling body in the second track.

[0036] like Figure 2 As shown, in a feasible technical solution, the limiting part 400 can be a rolling body, and there can be multiple rolling bodies, so that the rotating part 200 can rotate stably. One of the base 100 and the rotating part 200 can be provided with a first track 210, and the other can be provided with a plurality of positioning grooves 110 distributed around the rotation axis at intervals. The first track 210 can be an annular track groove around the rotation axis. Multiple rolling bodies can be positioned in the corresponding positioning grooves 110 and can roll in the positioning grooves 110. The rolling bodies and the first track 210 can roll in the direction around the rotation axis. The rolling bodies can respectively cooperate with the first track 210 and the corresponding positioning grooves in radial limiting.

[0037] In this structure, by setting the positioning groove 110, the rolling body can be positioned in the positioning groove 110, so that the movement of the rolling body can be constrained by the positioning groove 110, avoiding the rolling body from sliding relative to the first track 210, ensuring the rolling fit between the rolling body and the first track 210, which is beneficial to reduce the wear of the rolling body.

[0038] As described above, one of the base 100 and the rotating part 200 may be provided with a first track 210, and the other may be provided with a plurality of positioning grooves 110 spaced around the rotation axis. Based on this, in one embodiment, the first track 210 may be provided on the rotating part 200, and correspondingly, the positioning groove 110 may be provided on the base 100. In another embodiment, the first track 210 may be provided on the base 100, and correspondingly, the positioning groove 110 may be provided on the rotating part 200.

[0039] For further information, please refer to Figure 2 , multiple positioning grooves 110 can be spaced and evenly distributed around the rotation axis, and one or more rolling bodies can be set in each positioning groove 110. This structure can reduce the risk of deflection of the rotating part 200, and the multiple rolling bodies in this structure can bear the load more evenly, which is beneficial to improve the stability of the rotation support device.

[0040] In order to improve the stability of the fit between the rolling element and the positioning groove 110, the positioning groove 110 can be adapted to the shape of the rolling element, so that the rolling element can be more stably arranged in the positioning groove 110, so that the moving body can roll more stably in the positioning groove 110, so as to improve the stability of the fit between the rolling element and the positioning groove 110, thereby facilitating the improvement of the stability of the rotation of the rotating part 200. Specifically, when the rolling element is a ball, the positioning groove 110 can be a spherical groove, and when the rolling element is a needle, the positioning groove 110 can be an arc-shaped groove.

[0041] As described above, when the rolling body is a ball and the positioning groove 110 is a spherical groove, a plurality of spherical grooves can be spaced and evenly distributed around the rotation axis of the rotating part 200, and a plurality of balls can be positioned in the corresponding spherical grooves.

[0042] When the rolling element is a needle roller and the positioning groove 110 is an arc-shaped groove, a plurality of arc-shaped grooves can be spaced and evenly distributed around the rotation axis of the rotating part 200, and a plurality of needle rollers can be positioned in the corresponding arc-shaped grooves.

[0043] In a preferred technical solution, the rotating part 200 and the base 100 can be spaced apart, and an annular gap around the rotation axis can be formed between the two, and the rolling body can be arranged in the annular gap, and the rotating part 200 can be supported on the base 100 through the rolling body. This structure can avoid direct contact between the rotating part 200 and the base 100, so that the rotating part 200 can be supported on the base 100 through the rolling body, and when the rotating part 200 rotates, the rotating part 200 can be in rolling contact with the base 100 through the rolling body, thereby reducing the wear between the rotating part 200 and the base 100, and further facilitating the extension of the service life of the rotation support device.

[0044] Please refer to Figure 1 In an optional technical solution, the first track 210 may have a first accommodation depth for accommodating the rolling body, and the positioning groove 110 may have a second accommodation depth for accommodating the rolling body, and the second accommodation depth may be greater than the first accommodation depth. This structure allows most of the structure of the rolling body to be located in the positioning groove 110, so as to reduce the risk of the rolling body falling off from the positioning groove 110, which is conducive to improving the reliability of the rotation support device and facilitating the positioning of the rolling body in the positioning groove 110.

[0045] In the embodiment of the present application, the first track 210 may be an annular track groove, and the limiting portion 400 may be fixedly connected to the base 100. In one embodiment, the limiting portion 400 may be an annular protrusion, and during the rotation of the rotating portion 200, the annular protrusion and the first track 210 are slidably guided and matched in the direction around the rotation axis, and the annular protrusion may contact the side walls of the first track 210 on both sides of the extension direction to achieve radial limiting matching between the annular protrusion and the first track 210, so that the rotating portion 200 and the base 100 are radially limited and matched, and this structure is relatively simple and easy to implement.

[0046] In other embodiments, the limiting portion 400 may include a plurality of arc-shaped protrusions spaced apart around the rotation axis of the rotating portion 200. During the rotation of the rotating portion 200, the plurality of arc-shaped protrusions are all slidably guided and matched with the first track 210 in the direction around the rotation axis, and the plurality of arc-shaped protrusions may all contact the side walls distributed on both sides of the extension direction of the first track 210 to achieve radial limiting cooperation between the annular protrusion and the first track 210, thereby enabling the rotating portion 200 and the base 100 to be radially limited. This structure is beneficial for saving materials, thereby reducing costs.

[0047] Of course, in the case where the base is provided with a second track, and the second track is an annular track groove, the position-limiting portion 400 can be fixedly connected to the rotating portion 200. Based on this, in one embodiment, the position-limiting portion 400 can be an annular protrusion, and during the rotation of the rotating portion 200, the annular protrusion can be guided and matched with the second track in a sliding manner in the direction around the rotation axis as the rotating portion 200 rotates, and the annular protrusion can contact the side walls of the second track distributed on both sides of the extension direction to achieve radial position-limiting cooperation between the annular protrusion and the second track, so that the rotating portion 200 and the base 100 are radially position-limitingly matched. This structure is relatively simple and easy to implement.

[0048] In other embodiments, the limiting portion 400 may include a plurality of arc-shaped protrusions spaced apart around the rotation axis of the rotating portion 200. During the rotation of the rotating portion 200, the plurality of arc-shaped protrusions can be slidably guided and cooperated with the second track in the direction around the rotation axis as the rotating portion 200 rotates, and the plurality of arc-shaped protrusions can contact the side walls of the second track on both sides of the extension direction to achieve radial limiting cooperation between the annular protrusion and the second track, thereby achieving radial limiting cooperation between the rotating portion 200 and the base 100. This structure is beneficial to saving materials, thereby reducing costs.

[0049] Based on the rotation support device disclosed in the embodiment of the present application, the embodiment of the present application further discloses an electronic device, which includes a functional module and a rotation support device described in any one of the above embodiments, and the functional module is connected to the rotating part 200 so that the rotating part 200 can drive the functional module to rotate.

[0050] In the embodiment of the present application, the functional module can be a camera module or a fan module, or a projection module, a lighting module or a display screen, and the embodiment of the present application does not limit the specific type of the functional module. Accordingly, the electronic device can be a smart camera, a fan, a projector, a smart accompanying robot, etc., and the embodiment of the present application does not limit the specific type of the electronic device.

Considering the simplicity of the text, they will not be repeated here.
