Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is openly described in detail.Noting, the aspects described below in conjunction with the drawings and specific embodiments is merely illustrative of, and is understood not to protection domain disclosed in this utility model is carried out any restriction.
In the rest of the description and in the subsequent claims, the part of theme that this utility model the claims relation in operational conditions and between miscellaneous part that uses term " operationally " to represent, and be not offered as described theme and comprise described miscellaneous part.Such as, " theme A is operationally connected with spacing object B " represents that theme A (or its any parts) can be connected with spacing object B when operation, and theme A (or its any parts) not necessarily includes spacing object B.
Figure 1A and Figure 1B is shown respectively rearview and the axonometric chart of the stopping means 100 of some embodiments disclosed in this utility model.As it can be seen, stopping means 100 includes bracket 110, plate 120, rotating mechanism 130 and at least one buffer gear 140.
The part that bracket 110 can be used for spacing object contacts.In one embodiment, a part for spacing object can be the waist of human body or robot.Correspondingly, bracket 110 can have the curve shape of the waist profile meeting human body or robot.
Plate 120 can be used for contacting with another part of spacing object.In one embodiment, another part of spacing object can be the back of human body or robot.Correspondingly, plate 110 can be flat board, can be maybe curved slab.
Rotating mechanism 130 can include the first connector 131 and the second connector 132.First connector 131 can be fixed with bracket 110.Second connector 132 can be fixed with plate 120, and be connected to the second connector 132 with the first connector 131 and can rotate around a pivot center 150 relative to the first connector 131.
Second connector 132 can include fixing parts 132a and rotatable parts 132b.Fixing parts 132a can fix with plate 120, and can fix with rotatable parts 132b on the direction along pivot center 150.In certain embodiments, the fixed position of fixing parts 132a and rotatable parts 132b is adjustable on the direction along pivot center 150.
It is only can around solid fixed-axis rotation that the above-mentioned set-up mode of rotating mechanism 130 contributes to the kinematic constraint of spacing object.As particular example, when the back of human body is held against plate 120 and waist by bracket 110, the above-mentioned set-up mode of rotating mechanism 130 can by the kinematic constraint of human body waist for only can rotate around pivot center 150.Therefore, for, in the waist rehabilitations such as lumbar vertebra rehabilitation, unfavorable actions such as bending over can be avoided, thus being effectively improved rehabilitation efficiency.
In embodiment shown in Figure 1A and Figure 1B, the upper end of buffer gear 140, lower end can be pivotally connected with plate 120 and bracket 110 respectively.
Buffer gear 140 can include air spring body 141 and be pivotally connected assembly 142.In embodiment shown in Figure 1A and Figure 1B, the one end being pivotally connected assembly 142 is connectable to air spring body 141, and the other end can connect bracket 110 or plate 120.
As shown in Figures 1 A and 1 B 1, in certain embodiments, buffer gear 140 is two, and each buffer gear all includes air spring body 141 and is pivotally connected assembly 142 two of this air spring body 141 two ends.In a preferred embodiment, the two buffer gear is arranged in the both sides of pivot center 150, and is arranged symmetrically relative to pivot center 150.In a further embodiment, the position that buffer gear 140 is connected with plate 120 is farther from pivot center 150 compared to the position being connected with bracket 110.
Fig. 2 illustrates the structural representation of the buffer gear 140 of some embodiments disclosed in this utility model.As in figure 2 it is shown, buffer gear 140 can include air spring body 141 and be pivotally connected assembly 142.
Air spring body 141 can include cylinder 210, piston rod 220 and piston 230.Cylinder 210 has hole at the first end 210a place.Piston rod 220 can enter cylinder 210 via this hole.Piston rod 220 is fixed with piston 230 at the second end 220b place.It is filled with gas (such as, nitrogen) in cylinder 210, and near open side 210a place, there is sealing 240.When operation, by pushing and pull out piston rod 220, can increase or reduce the stroke S of piston rod 220, thus changing the overall length L of air spring body 141.In this utility model, term " stroke " (S) refers to the distance between the first end 220a of piston rod 220 and the first end 210a of cylinder 210, and term " overall length " (L) refers to the distance between the first end 220a of piston rod 220 and the second end 210b of cylinder 210.Under the driving of piston rod 220, piston 230 promotes the gas within cylinder 210 to move.In pushing course, piston 230 can be subject to the resistance of gas on promotion face and make the propelling of piston 230 hindered, thus forming buffering effect.Additionally, the variable quantity of stroke S is more big, this buffering effect is more obvious.Therefore, use air spring body 141 not only can retrain the motion of piston rod 220, and in the process increasing or reducing of stroke S, also there is ever-increasing buffering effect.
In certain embodiments, can suitably selected following one or more parameters so that buffer gear 140 will not touch bracket 110 when operation: the stroke S of air spring body 141, overall length L, cylinder 210 external diameter etc..
As a particular example, stopping means can to the rotary spacing of human body waist.Specifically, the back of human body can rest on plate 120.Plate 120 can be made to rotate during the waist twisting of human body, thus driving rotating mechanism 130 to rotate around pivot center 150.At plate 120 in the process that pivot center 150 rotates, the rotation of plate 120 is limited within the specific limits by least one buffer gear 140.The scope rotated can be determined by the excursion of the stroke S of the air spring body 141 of buffer gear 140.Additionally, as discussed above in conjunction with Fig. 2, the change of stroke S is more big, and the buffering effect of air spring body 141 is more notable.Therefore, in this application, stopping means 100 can be prevented effectively from the twisting that the waist of human body is excessive, too fast, thus avoiding waist to come to harm.
In a further embodiment, two air spring bodies are all in time under poised state, and respective and 150 angle degree of pivot center range for 15-30 °.It is advantageous that this angular range both can for needing spacing waist offer to rotate flexibly, can prevent from again rotating excessively provides protection.In a particular embodiment, this angle is 30 °.Exemplarily, can at two air spring bodies 141 all in installing them into time under poised state on bracket 110 and plate 120.In this example, when being arranged in horizontal plane by bracket 110, air spring 131 can be highly vertically 130mm, and floor projection distance can be 52mm, the slewing area making plate 120 is limited in ± 10 ° of (that is, being 10 ° to the maximum on each direction) scopes in.For the application that waist is spacing, it is believed that the spacing scope of ± 10 ° may conform to human body and sways one's hips the needs of action.In a further embodiment; this angle can be 20 ° or 25 °; different angles may correspond to different spacing scopes, provides different grades of position limitation protection (such as, the injured limited range of activity of more serious waist is less) hence for the waist needing different protection class.
In this utility model, " poised state " of air spring body refers to the state (that is, air spring body does not produce the state of position-limiting action) that air spring body neither stretches, also do not compress.
