As shown in fig. 1 to 4, the first embodiment of the clutch mechanism 100 of the present invention includes: a clutch body assembly C, a housing 4 and a preventing member 5 a.
The clutch body assembly C includes a driving plate 1, an input member 2 and an acting assembly 3. Wherein, the driving disc 1 has a concave portion 11 and a first enclosing wall 12 surrounded by the corresponding concave portion 11; the input component 2 comprises a cam 21 and a locking block 22, the cam 21 is provided with an outer upper wall 211, and the locking block 22 protrudes out of the outer upper wall 211; the acting assembly 3 comprises a plurality of rollers 31 and a plurality of elastic assemblies 32. The input part 2 and the action component 3 are movably arranged in the concave part 11. The shape of the driving disc 1 after the cross section may be, for example, a U-shape as shown in fig. 4. Wherein the plurality is three or more.
It should be noted that, as shown in fig. 4, the clutch body assembly C has an axial center X, and the clutch body assembly C defines an axial direction a with the axial center X and further defines a radial direction R perpendicular to the axial direction a.
The housing 4 covers the drive disc 1 in correspondence with the recess 11. Housing 4 has a cover plate 41 and a second bounding wall 42. Wherein, the cover plate 41 covers corresponding to the recess 11 and has an inner upper wall 411 (see fig. 4), and the inner upper wall 411 and the outer upper wall 211 are axially opposite to each other; second perimeter wall 42 surrounds the perimeter edge connected to cover plate 41, and first perimeter wall 12 and second perimeter wall 42 are diametrically opposed to each other.

Thus, by the same object: the object is prevented, and the function of preventing abrasion and the function of preventing shaking are simultaneously provided. It should be noted that the term "shake" as used herein refers to that any number of components are easily shaken due to gaps between the components after the components are assembled.
In detail, as shown in fig. 2 and 4, the preventing member 5a is a disk 51 in the present embodiment, and the disk 51 is separated from the housing 4 and the clutch body assembly C along the axial direction a to prevent the axial abrasion therebetween; the disc 51 is particularly shown as being spaced between the cover plate 41 and the part of the clutch body assembly C axially opposite to the cover plate 41 (e.g. comprising the upper edge of the second bounding wall 12, the outer upper wall 211 of the cam 21 and the upper edge of the acting element 3) as shown in fig. 4. In addition, the disc 51 further has a connection part 513 and the aforementioned at least two support parts, the number of the support parts is not limited in the present invention, and in this embodiment, two are taken as an example for description and include a first axial support part 511 and a second axial support part 512, the connection part 513 is connected between the first axial support part 511 and the second axial support part 512 in a turning manner as shown in fig. 4, the first axial support part 511 and the second axial support part 512 are connected via the turning of the connection part 513 and are higher and lower, so that the disc 51 can be elastically supported between the outer cover 4 and the clutch main assembly C by the first axial support part 511 and the second axial support part 512; therefore, the disk 51 can also be supported by the first axial support portion 511 and the second axial support portion 512 in the axial direction a on the inner upper wall 411 of the cover plate 41 and the outer upper wall 211 of the cam 21, respectively, while preventing axial shaking therebetween.
In other words, the disk 51 has both functions of preventing axial abrasion and preventing axial shaking, that is: the first axial support portion 511, the second axial support portion 512 and the connecting portion 513 are collectively separated between the outer cover 4 and the clutch body assembly C to prevent axial wear.
Further, as shown in fig. 2, the first axial support portion 511, the connecting portion 513, and the second axial support portion 512 of the disk 51 are coaxially arranged with each other.
In addition, in order to prevent the object 5a from following and rotating during the height adjustment operation of the seat, as shown in fig. 1, at least one positioning member 412 is disposed on the housing 4, in this embodiment, a plurality of positioning members 412 are taken as an example for illustration, and the positioning member 412 can be a convex key or a lug (but not limited thereto); the disc 51 of the preventing object 5a is provided with a plurality of positioning parts 55 corresponding to the positioning parts 412, and the positioning parts 55 may be grooves or insertion holes (but not limited thereto). Thus, as shown in fig. 1 to 3, after the driving disc 1 is covered by the housing 4 and assembled, the positioning parts 55 are inserted into the positioning parts 412, so that the object 5a is prevented from being restricted by the positioning parts 412 and can be prevented from rotating.
As shown in fig. 5 and 6, a second embodiment of the present invention is shown. The second embodiment is substantially the same as the first embodiment, and the difference is only in the prevention object 5b, which will be described in detail later.
The preventing member 5b comprises a disk 53 and a support structure 54 surrounding the periphery of the disk 53.
The disc 53 is simply a flat disc without a supporting effect. The disc 53, like the disc 51 described above, is also disposed between the outer cover 4 and the clutch body assembly C and is also spaced apart in the axial direction a between the cover plate 41 and the portion of the clutch body assembly C axially opposite to the cover plate 41 to prevent axial wear therebetween, and the disc 53 is also provided with a plurality of positioning portions 55.
The support structure 54 may be a single ring wall (not shown) or may be at least two curved spring arms 541 connected to the periphery of the disk 53 and formed in multiple pieces as shown. Taking a single annular wall as an example, the annular wall is bent along the axial direction a to form the at least two support parts belonging to the bent top and the bent bottom respectively in the same bent structure; taking the multi-piece at least two bending spring arms 541 as an example, each bending spring arm 541 is bent along the axial direction a to have the at least two support portions belonging to the bending top and the bending bottom, respectively, in the same bending structure. Moreover, the supporting portions of the ring wall or the bending spring arm 541 are also supported between the outer cover 4 and the driving disk 1 along the radial direction R, respectively, to prevent radial wobbling therebetween.
The number of the supporting portions is not limited in the present invention, and two supporting portions are taken as an example in the present embodiment to include a first radial supporting portion 5411 and a second radial supporting portion 5412. The first radial support portion 5411 and the second radial support portion 5412 of each bending spring arm 541 are supported in the radial direction R by the first enclosing wall 12 and the second enclosing wall 42, respectively, to prevent radial wobbling.
As shown in fig. 7 and 8, a third embodiment of the present invention is shown. The third embodiment is substantially the same as the first or second embodiment, and the difference is only that the preventing member 5c of the third embodiment is different, as will be described later.
The preventive piece 5c is a mixture of the preventive piece 5a of the first embodiment and the preventive piece 5b of the second embodiment. In detail, the preventing member 5c includes a plate 51 (the same as the plate 51 of the preventing member 5 a) and a supporting structure 54 (the same as the supporting structure 54 of the preventing member 5 b) surrounding the periphery of the plate 51, so that the supporting structure 54 of the preventing member 5c can also be a single ring wall (not shown) or at least two bending elastic arms 541 of multiple pieces.
Thereby, the preventing member 5c in the third embodiment will have all the effects of the first and second embodiments at the same time: the disc 51 can serve to prevent axial abrasion and axial vibration, and the support structure 54 can serve to prevent radial vibration.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings are included in the scope of the present invention, and it is obvious that the present invention is also included in the scope of the present invention.
