Wherein the second bracket assembly 3 is rotatable relative to the first bracket assembly 2 about a rotation axis R by the joint 1.

In more detail, as shown in fig. 1, 3 and 4, the first support assembly 2 includes a base 21, a lift adjustment mechanism 22 mounted on the base 21, and a plurality of first pads 23. Wherein the base 21 is connected to the first connection 11 of the joint 1, for example: one end of the first connecting member 11 is inserted into and fixed to the base 21. In addition, a track groove 211 is formed in the base 21, and the track groove 211 is formed by an end of the base 21 away from the joint 1 being recessed inward along a lifting direction L, but the utility model is not limited thereto.

The elevation adjusting mechanism 22 is movably installed in the rail groove 211 of the base 21, and the elevation adjusting mechanism 22 is composed of a plurality of members assembled with each other in this embodiment; that is, any lift assembly in the form of a single member is different from the lift adjustment mechanism 22 referred to in this embodiment.

In more detail, the lifting adjusting mechanism 22 includes a lifting rod 221, a coupling member 222 detachably mounted to the lifting rod 221, and a curved rod member 223 detachably mounted to the coupling member 222. In this embodiment, the lifting rod 221 is a straight rod-shaped single-piece structure, and the lifting rod 221 is movably disposed in the track groove 211 along the lifting direction L and fixed at a predetermined position (according to actual requirements).

One end of the coupling member 222 is inserted into and screw-locked to the lifting rod 221, and the other end of the coupling member 222 is screw-locked to the curved rod member 223. Further, the engaging piece 222 is formed to extend obliquely from the one end toward the other end thereof with respect to the lifting direction L (e.g., the engaging piece 222 is formed to extend obliquely slightly toward the upper right in FIG. 4).

Viewed from another perspective, the joint 222 is a single-piece structure and includes a first section 2221, a second section 2222, and a third section 2223 connected between the first section 2221 and the second section 2222. The first section 2221 is inserted into and screwed to the lifting rod 221, the second section 2222 is screwed to the curved rod 223, and the first pads 23 are respectively mounted on the base 21 and the (third section 2223 of the) engaging member 222.

In addition, the joint 222 (in the third section 2223) is formed with a tubular portion 2224, and the space surrounded by the lifting rod 221 is communicated with the space surrounded by the tubular portion 2224, and is thereby communicated with the external space. In this embodiment, the joint member 222 includes a through channel 2225 recessed from the tubular portion 2224 through the first section 2221, and the space surrounded by the lifting rod 221 can be communicated with the external space through the through channel 2225.

Further, the bent rod member 223 is a one-piece structure, and each portion of the bent rod member 223 has the same thickness. In this embodiment, the curved bar member 223 includes two curved segments 2231 connected to each other, and a portion where the two curved segments 2231 are connected to each other is a point of inflection, and one of the curved segments 2231 is screwed to the second section 2222 of the joint member 222, but the utility model is not limited thereto. That is, the specific configuration of the curved bar member 223 can be adjusted according to the design requirement.

As described above, the human body aid 100 according to the embodiment of the present invention assembles the lifting rod 221 and the curved rod member 223 through the connecting member 222, so as to effectively reduce the forming difficulty and the manufacturing cost of the curved rod member 223, and facilitate the lifting adjusting mechanism 22 to adopt the curved rod member 223 with a suitable structure according to actual requirements.

In the above description of the structural improvement of the first bracket assembly 2 in the present embodiment, the structural improvement of the second bracket assembly 3 in the present embodiment is described below.

As shown in fig. 6 to 8, the second frame assembly 3 includes a pivot frame 31 corresponding to the second connecting member 12, a second cushion 32 mounted on the pivot frame 31, a plurality of torsion pieces 33 abutting against the pivot frame 31, and a shaft 34. It should be noted that the shaft 34 is implemented by a nut in fig. 7 of the present embodiment, but in other embodiments not shown in the present invention, the shaft 34 may be screwed to the object through which it passes (e.g., the pivot bracket 31 is formed with a thread corresponding to the shaft 34).

The pivot bracket 31 includes a supporting body 311 and two pivot seats 312 formed at intervals on the supporting body 311, and the second pad 32 is mounted on the supporting body 311, and a part of the second connecting member 12 is disposed between the two pivot seats 312. In addition, the shaft 34 is disposed through the pivoting bracket 31 (e.g., two pivoting seats 312), each of the torsion pieces 33, and the second connecting member 12 (e.g., the portion of the second connecting member 12 located between the two pivoting seats 312).

Accordingly, the pivot bracket 31 can rotate relative to the second connector 12 with the length direction of the shaft lever 34 as an axis, and the length direction of the shaft lever 34 is not parallel to the rotation axis R in this embodiment, but the utility model is not limited thereto. In addition, the torsion pieces 33 are respectively clamped between the pivot bracket 31 and the shaft rod 34 and between the pivot bracket 31 and the second connecting member 12, so that the second bracket assembly 3 can adjust the overall torsion and control the rotation angle of the pivot bracket 31 by providing the torsion pieces 33.

It should be noted that the specific configuration of the torque plate 33 can be adjusted according to the design requirement, and the embodiment only describes one possible configuration of the torque plate 33 in the following description, but the utility model is not limited thereto.

Specifically, each of the torsion pieces 33 has a ring body 331 and a retaining portion 332 extending perpendicularly from an edge of the ring body 331. The ring bodies 331 of the torsion pieces 33 are respectively clamped between (two pivoting seats 312 of) the pivoting bracket 31 and the shaft rod 34 and between (two pivoting seats 312 of) the pivoting bracket 31 and the second connecting member 12, so that a preset torsion value is correspondingly derived through friction between each ring body 331 and its abutting components. In addition, the buckling parts 332 of the plurality of torque plates 33 are respectively embedded in the pivot bracket 31 and the second connecting member 12, so as to prevent any one of the torque plates 33 from rotating.

Further, the cross section of the shaft 34 is non-circular, and the section of the portion of the shaft 34 sleeved on the second connector 12 is also non-circular correspondingly, so the relative positions of the shaft 34 and the second connector 12 are constantly kept fixed. In addition, a circular through hole is formed in each of the two pivoting seats 312 of the pivoting bracket 31, and the ring 331 of each torque piece 33 also surrounds and forms a circular through hole, and the shaft 34 passes through the circular through hole of each pivoting seat 312 and the circular through hole of each torque piece 33, so that the pivoting bracket 31 and the torque piece 33 fastened thereon can rotate relative to the shaft 34.

Accordingly, when the pivot bracket 31 pivots relative to the second connecting member 12, the two pivot seats 312 and the torque plates 33 fastened thereon can rotate together, so that a predetermined torque value is correspondingly derived by friction between components (such as the shaft rod 34 and the torque plates 33 fastened on the second connecting member 12) which are fastened to the torque plates 33 of the two pivot seats 312 and abut against the components.

In addition, the number of the torque pieces 33 is illustrated as a plurality in the present embodiment, but the present invention is not limited thereto. For example, in other embodiments not shown in the drawings, the number of the torque pieces 33 may be at least one, and the shaft 34 is inserted through the pivot bracket 31, at least one of the torque pieces 33, and the second connecting member 12, so that at least one of the torque pieces 33 is clamped between the pivot bracket 31 and the shaft 34 or between the pivot bracket 31 and the second connecting member 12.

In addition, the human body assistive device and the support assembly thereof disclosed by the embodiment of the utility model have the advantages that the integral torque force can be effectively adjusted and the rotation angle of the pivoting support can be controlled by arranging the at least one torque piece.

The disclosure is only a preferred embodiment of the utility model and is not intended to limit the scope of the utility model, so that all equivalent technical changes made by using the contents of the specification and drawings are included in the scope of the utility model.
