Description

Technical Field

[0001] The utility model relates to the technical field of rotating mechanism manufacturing, in particular to a rotating mechanism. Background Art

[0002] In the prior art, due to appearance or spatial layout, the center of mass position and the rotation axis of rotating products often cannot coincide. When rotating the rotating part, it is easier to rotate the rotating part downward.

In addition, after long-term use and aging, the friction torque of the shaft hole or the torque attenuation of the damping structure may be generated, which will aggravate the instability of the product's rotational motion.

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Please refer to the following Figure 1-7 A rotating mechanism 100 according to an embodiment of the present invention is described.

[0032] Reference Figure 1 and Figure 2 According to the embodiment of the utility model, the rotating mechanism 100 includes: a mounting frame 10 and a rotating assembly 20. The rotating assembly 20 includes: a rotating member 30 and an adjusting member 40. The rotating member 30 is rotatably arranged on the mounting frame 10, and the rotation axis of the rotating member 30 does not coincide with the center of mass; the adjusting member 40 is arranged on the rotating member 30, and the adjusting member 40 is configured to adjust the center of mass of the rotating assembly 20 so that the center of mass of the rotating assembly 20 coincides with the rotation axis of the rotating member 30.

[0033] For example, Figure 1 and Figure 2 As shown, the rotation axis of the rotating member 30 is at the axial center position of the rotating member 30. Due to the design of the rotating member 30 and the arrangement of structures such as blades, the center of mass of the rotating member 30 usually deviates from the position of the rotation axis of the rotating member 30, so that the center of mass of the rotating member 30 does not coincide with the rotation axis. The adjusting member 40 cooperates with the rotating member 30 to make the center of mass of the rotating assembly 20 coincide with the rotation axis of the rotating member 30.

[0034] In the present solution, when the rotating member 30 is rotated, the rotating member 30 rotates relative to the mounting frame 10. At the same time, the adjusting member 40 rotates synchronously with the rotating member 30. The adjusting member 40 cooperates with the rotating member 30 to make the center of mass of the rotating assembly 20 coincide with the rotation axis of the rotating member 30. When the rotating member 30 rotates in any direction relative to the mounting frame 10, equal operating force can be provided, thereby improving the user experience.

[0035] The rotating mechanism 100 of the utility model is provided with an adjusting member 40, and the adjusting member 40 cooperates with the rotating member 30 to make the center of mass of the rotating component 20 coincide with the rotation axis of the rotating member 30. When the rotating member 30 rotates relative to the mounting frame 10, the problem of providing different operating forces for the rotating member 30 to rotate in different directions can be solved, thereby achieving smooth rotation and smooth operation of the rotating member 30, thereby improving the operating experience. At the same time, even if the matching structure between the rotating member 30 and the mounting member ages, for example, friction occurs between the rotating member 30 and the mounting frame 10 or the damping force between the rotating member 30 and the mounting frame 10 decays, the adjusting member 40 can always cooperate with the rotating member 30 to make the center of mass of the rotating component 20 coincide with the rotation axis of the rotating member 30, thereby ensuring a good operating experience of the rotating mechanism 100 during the operation cycle.

[0036] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The adjusting member 40 includes a counterweight 41, which is movably arranged on the rotating member 30. When the rotating member 30 rotates, the counterweight 41 is driven to move to adjust the center of mass position of the rotating assembly 20. Therefore, the counterweight 41 has weight, and during the rotation of the rotating member 30, the counterweight 41 can adjust the center of mass position of the rotating assembly 20.

[0037] According to some embodiments of the present invention, referring to Figure 2 A guide groove 122 is provided on the mounting frame 10, and the counterweight block 41 can slide along the guide groove 122. Any position of the counterweight block 41 in the guide groove 122 satisfies: G×L=F×D, wherein G is the gravity of the rotating member 30, L is the distance between the rotation axis of the rotating member 30 and the center of mass of the rotating member 30 in the horizontal plane, F is the gravity of the adjusting member 40, and D is the distance between the rotation axis of the rotating member 30 and the center of mass of the adjusting member 40 in the horizontal plane.

[0038] In this way, the force multiplied by the lever arm is the torque, and the torque from the rotating part 30 to the rotation axis is always equal to the torque from the counterweight 41 to the rotation axis. According to the formula, it can be deduced that the counterweight 41 can adjust the center of mass of the rotating component 20 to a position that coincides with the rotation axis, and then the weight and moving path of the counterweight 41 can be calculated, and the extension direction of the guide groove 122 can be obtained according to the moving path. When the counterweight 41 moves along the extension direction of the guide groove 122, the center of mass of the rotating component 20 can be coincident with the rotation axis at any position, so that in the process of rotating the rotating part 30, a smooth operating force can be used to achieve smooth rotation of the rotating part 30.

[0039] Furthermore, if Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, when the rotating member 30 is in the initial position, G×R1×COSα=F×D1, wherein R1 is the straight-line distance from the center of mass of the rotating member 30 at the initial position to the axis of rotation, α is the angle between the line connecting the center of mass of the rotating member 30 at the initial position and the axis of rotation and the horizontal direction, and D1 is the horizontal projection distance from the center of mass of the counterweight block 41 at the initial position to the axis of rotation.

[0040] Furthermore, if Figure 7 As shown, when the rotating member 30 rotates to a certain position, G×R1×COS(α+β)=F×D2, wherein β is the rotation angle of the rotating member 30 relative to the initial position of the rotating member 30, and D2 is the horizontal projection distance from the center of mass of the counterweight block 41 after rotation to the rotation axis.

[0041] Changing the formula, we can get: △X=D1-D2=(G×R1 / F)×[COSα-COS(α+β)], △Z=R2×tanβ, where △X is the horizontal movement distance of the counterweight 41, and △Z is the vertical movement distance of the counterweight 41. Thus, the movement trajectory of the counterweight 41 can be calculated, and the extension direction of the guide groove 122 can be obtained, which can ensure that the center of mass of the rotating assembly 20 coincides with the rotation axis when the rotating member 30 rotates to any position.

[0042] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The adjusting member 40 includes: a connecting component 42, one end of the connecting component 42 (such as Figure 2 The front end of the connecting assembly 42 shown in FIG. 1 is eccentrically arranged relative to the rotation axis of the rotating member 30 and is rotatably connected to the rotating member 30. The other end of the connecting assembly 42 (as shown in FIG. 1 ) is eccentrically arranged relative to the rotation axis of the rotating member 30 and is rotatably connected to the rotating member 30. Figure 2 The rear end of the connecting assembly 42 shown in the figure is connected to the counterweight 41, and the connecting assembly 42 is connected along its own length direction (such as Figure 2 The front and rear directions shown) are retractable.

[0043] In this way, the connecting component 42 is eccentrically connected to the rotating member 30, thereby ensuring that the connecting component 42 can be driven to rotate when the rotating member 30 rotates. At the same time, the connecting component 42 is retractable along the length direction. When the connecting component 42 drives the counterweight block 41 to move, the distance from the center of mass of the counterweight block 41 to the axis of rotation can be adjusted, thereby adjusting the torque between the counterweight block 41 and the axis of rotation, thereby ensuring that the center of mass of the rotating component 20 coincides with the axis of rotation.

[0044] For example, Figure 1 and Figure 2As shown, the connecting component 42 extends in the front-to-back direction, the front end of the connecting component 42 is connected to the axle pin on the surface of the rotating member 30, the axle pin is eccentric relative to the rotation axis, and the rear end of the connecting component 42 is connected to the counterweight block 41. The connecting component 42 can extend and retract in the front-to-back direction, and can drive the counterweight block 41 to move in the front-to-back direction.

[0045] According to some optional embodiments of the present invention, referring to Figure 2 The connecting assembly 42 includes: a first connecting rod 421 and a second connecting rod 422. One end of the first connecting rod 421 (such as Figure 2 The front end of the first connecting rod 421 shown in FIG. 4 is connected to the rotating member 30; one end of the second connecting rod 422 (as shown in FIG. Figure 2 The front end of the second connecting rod 422 shown in FIG. 4 is movably connected to the first connecting rod 421 along the extension direction of the first connecting rod 421, and the other end of the second connecting rod 422 (as shown in FIG. Figure 2 The rear end of the second connecting rod 422 shown is connected to the counterweight 41.

[0046] In this way, the first connecting rod 421 is connected to the rotating member 30, and the rotation of the rotating member 30 can drive the connecting component 42 to rotate. The second connecting rod 422 can move relative to the first connecting rod 421. When the first connecting rod 421 drives the second connecting rod 422 to rotate, the second connecting rod 422 moves on the first connecting rod 421 at the same time, so that the distance between the second connecting rod 422 and the first connecting rod 421 can be adjusted. When the second connecting rod 422 drives the counterweight block 41 to move, the distance between the center of mass of the counterweight block 41 and the horizontal projection of the rotation axis can be adjusted, and then the torque between the counterweight block 41 and the rotation axis can be adjusted.

[0047] For example, Figure 2 As shown, the first link 421 extends in the front-to-back direction, the front end of the first link 421 is connected to the rotating member 30, the rear end of the first link 421 is connected to the second link 422, the second link 422 extends in the front-to-back direction, the front end of the second link 422 is connected to the rear end of the first link 421, the rear end of the second link 422 is connected to the counterweight 41, and the second link 422 can move forward and backward on the first link 421.

[0048] According to some optional embodiments of the present invention, referring to Figure 2 The second connecting rod 422 is provided with a Figure 2 The other end of the first connecting rod 421 (as shown in the front and rear direction) extends through a connecting hole. Figure 2 The rear end of the first connecting rod 421 shown in the figure can be movably inserted into the connecting hole. Therefore, the connection hole can facilitate the connection between the first connecting rod 421 and the second connecting rod 422. At the same time, the extending direction of the connecting hole is the same as the moving direction of the second connecting rod 422, so that the second connecting rod 422 can be moved relative to the first connecting rod 421.

[0049] For example, Figure 2 As shown, a connecting hole is formed at the front end of the second connecting rod 422, and the connecting hole extends along the front-rear direction. The rear end of the first connecting rod 421 is inserted into the connecting hole and can move along the extending direction of the connecting hole.

[0050] According to some optional embodiments of the present invention, referring to Figure 2 The adjusting member 40 further includes a moving frame 43, which is movably disposed on the mounting frame 10, and the counterweight 41 is disposed on the moving frame 43. Thus, the moving frame 43 can provide a supporting position for the counterweight 41, thereby preventing the counterweight 41 from being separated from the connecting assembly 42. At the same time, the moving frame 43 is movable on the mounting frame 10, thereby driving the counterweight 41 to move.

[0051] According to some optional embodiments of the present invention, referring to Figure 2 , the moving frame 43 moves along the first direction (such as Figure 2 The front and rear directions shown in FIG. 1 are movably arranged on the mounting frame 10, and the movable frame 43 is provided with a movable portion along the second direction (such as Figure 2 The first track 432 extends in the up-down direction (as shown in the figure), and the counterweight 41 is movably arranged in the first track 432 along the second direction, and the second direction is perpendicular to the first direction.

[0052] In this way, when the movable frame 43 moves in the first direction and the counterweight 41 moves in the first track 432, the counterweight 41 can be moved along the extension direction of the guide groove 122, so that the counterweight 41 can be moved along a moving path that can make the center of mass of the rotating component 20 coincide with the axis of rotation, thereby enabling the rotating member 30 to rotate smoothly.

[0053] For example, Figure 2 As shown, the moving frame 43 is in a ring shape extending in the up-down direction, and a first track 432 extending in the up-down direction is defined in the moving frame 43 . The counterweight 41 can move in the first track 432 in the up-down direction.

[0054] According to some optional embodiments of the present invention, referring to Figure 2 The movable frame 43 is provided with a protrusion 431, and the mounting frame 10 is provided with a second track 121, and the second track 121 is along the first direction (such as Figure 2 The convex portion 431 is movably disposed in the second track 121. Thus, the movable frame 43 can move along the first direction in the second track 121, and the movable frame 43 cooperates with the second track 121, so that the counterweight 41 can move in the guide groove 122.

[0055] For example, Figure 2As shown, a protrusion 431 is provided on a side surface of the movable frame 43 facing the mounting frame 10, and the protrusion 431 extends toward the mounting frame 10. A corresponding second track 121 is provided on the mounting frame 10, and the second track 121 extends along the front-to-back direction. The protrusion 431 extends into the second track 121 and can move forward and backward along the second track 121.

[0056] Furthermore, if Figure 2 As shown, the protrusions 431 are arranged on the front and rear sides of the moving frame 43 , and two corresponding second rails 121 are arranged on the mounting frame 10 . Each protrusion 431 extends into the corresponding second rail 121 to enable the moving frame 43 to move smoothly in the second rail 121 .

[0057] According to some embodiments of the present invention, referring to Figure 2 The mounting frame 10 includes: a back plate 11 and a side plate 12. The number of the side plates 12 is two, and the two side plates 12 are respectively connected to the back plate 11 in the length direction (such as Figure 2 The rotating assembly 20 is disposed between the two side plates 12 and is rotatably connected to the two side plates 12, and the adjusting member 40 is disposed between the rotating assembly 20 and the side plates 12.

[0058] In this way, the back plate 11 and the two side plates 12 form the main structure of the mounting frame 10, thereby ensuring the strength of the mounting frame 10 and preventing damage to the mounting frame 10. At the same time, the back plate 11 and the two side plates 12 define the installation space of the rotating component 20, which facilitates the arrangement of the rotating component 20. Furthermore, an arrangement space for the adjusting member 40 is reserved between the rotating component 20 and the mounting frame 10, which facilitates the arrangement of the adjusting member 40.

Thus, the air outlet channel is connected to the air inlet channel 111, and the air inlet is connected to the air outlet 31, and the air flow can flow out of the rotating mechanism 100 from the air inlet channel 111 through the air inlet, the air outlet channel and the air outlet 31 in sequence, thereby ensuring the normal air outlet of the rotating mechanism 100.

[0061] For example, Figure 2 As shown, an air inlet channel 111 is provided on the back plate 11 of the mounting frame 10, and the air inlet channel 111 extends in the front-to-back direction. An air outlet channel extending in the front-to-back direction is defined in the rotating member 30, and an air outlet 31 is formed at the front end of the air outlet channel, and an air inlet is formed at the rear end of the air outlet channel, and the air inlet is connected to the air inlet channel 111.
