省力輔助裝置Labor-saving assistive device

本發明是有關於一種針對人體動作的輔助裝置，特別是指一種省力輔助裝置。The present invention relates to an assistive device for human body movements, and in particular to a labor-saving assistive device.

參閱圖1，為一種現有之穿戴於人體的動作輔助裝置1，該動作輔助裝置1包含一界定出一內空間100的本體10、一穿設於該本體10且能相對於該本體10轉動的轉輪11、一連接於該轉輪11且能與該轉輪11一同轉動的銜接件12、一與該本體10相鄰設置的阻尼器13，及一繞設於該轉輪11且遠離該轉輪11之一端連接於該阻尼器13的牽引索14。該銜接件12能在一初始位置，及一帶動該轉輪11轉動而使該牽引索14施力於該阻尼器13，並使該阻尼器13產生一輔助力的作動位置間移動。該動作輔助裝置1的該銜接件12，得以連結至少一能因應人體之動作而使該銜接件12帶動該轉輪11轉動的抵配件19。藉由各式各樣穿戴於人體不同部位的該抵配件19，即得以利用該阻尼器13產生的該輔助力，達成輔助人體對應該抵配件19之動作的目的。Referring to FIG. 1 , there is shown a conventionalmotion assisting device 1 worn on a human body, themotion assisting device 1 comprising abody 10 defining aninner space 100, a rotatingwheel 11 penetrating thebody 10 and capable of rotating relative to thebody 10, acoupling 12 connected to the rotatingwheel 11 and capable of rotating together with the rotatingwheel 11, adamper 13 disposed adjacent to thebody 10, and atraction cable 14 wound around the rotatingwheel 11 and having one end away from the rotatingwheel 11 connected to thedamper 13. Thecoupling 12 can move between an initial position and an actuating position in which the rotatingwheel 11 is driven to rotate so that thetraction cable 14 applies force to thedamper 13 and thedamper 13 generates an assisting force. Thejoint 12 of themotion assisting device 1 can be connected to at least oneabutment 19 that can drive the rotatingwheel 11 to rotate in response to the motion of the human body. By wearingvarious abutment 19 on different parts of the human body, the auxiliary force generated by thedamper 13 can be utilized to achieve the purpose of assisting the human body's motion corresponding to theabutment 19.

然而，穿戴該動作輔助裝置1時，人體即便不是進行該動作輔助裝置1預期會產生輔助效果的動作，也仍有可能會牽動該抵配件19，因而使得該動作輔助裝置1作動，並且產生非預期的無謂輔助而造成干擾。若是為了避免前述干擾，在不執行需要輔助之工作時選擇脫下該動作輔助裝置1，直到需要重新開始工作時才再穿戴，又會造成需要反覆穿卸該動作輔助裝置1的麻煩。However, when wearing themotion assisting device 1, even if the human body is not performing the motion that themotion assisting device 1 is expected to produce an assisting effect, theabutment 19 may still be pulled, thereby causing themotion assisting device 1 to be activated and produce unexpected unnecessary assistance and cause interference. In order to avoid the aforementioned interference, if themotion assisting device 1 is taken off when not performing the work that requires assistance and is not put on again until it is necessary to resume work, it will cause the trouble of repeatedly putting on and taking off themotion assisting device 1.

因此，本發明之目的，即在提供一種更適合長時間穿戴，並能更精準地因應人體自身動作而提供輔助的省力輔助裝置。Therefore, the purpose of the present invention is to provide a labor-saving auxiliary device that is more suitable for long-term wear and can provide assistance more accurately in response to the body's own movements.

於是，本發明省力輔助裝置，適用於供一人體穿戴，並包含一運作單元、一連接於該運作單元且用以使該運作單元定位於人體的穿戴單元，及一安裝於該運作單元的控制單元。Therefore, the labor-saving auxiliary device of the present invention is suitable for being worn by a human body, and comprises an operating unit, a wearable unit connected to the operating unit and used to position the operating unit on the human body, and a control unit installed on the operating unit.

該運作單元包括一本體、一穿設於該本體且能沿一轉軸線相對於該本體轉動的轉輪、一連接於該轉輪且能與該轉輪一同轉動的銜接件、一與該本體相鄰設置的阻尼器，及一繞設於該轉輪且遠離該轉輪之一端連接於該阻尼器的牽引索。該運作單元之該銜接件能在一初始位置，及一帶動該轉輪轉動而使該牽引索施力於該阻尼器，並使該阻尼器產生一輔助力的作動位置間移動。The operation unit includes a body, a rotating wheel passing through the body and capable of rotating relative to the body along a rotating axis, a coupling connected to the rotating wheel and capable of rotating together with the rotating wheel, a damper disposed adjacent to the body, and a traction rope wound around the rotating wheel and connected to the damper at one end away from the rotating wheel. The coupling of the operation unit can move between an initial position and an actuating position in which the rotating wheel is driven to rotate so that the traction rope applies force to the damper and the damper generates an auxiliary force.

該穿戴單元包括一適用於抵接該人體至少一部分的接觸件，及一與該接觸件連動的傳動軸。The wearable unit includes a contact piece adapted to abut against at least a portion of the human body, and a transmission shaft linked to the contact piece.

該控制單元包括一連接於該運作單元之該銜接件並供該傳動軸穿設的殼體，及一安裝於該殼體的離合機構。該離合機構能在一使該穿戴單元之該傳動軸與該運作單元之該銜接件一同作動的連動位置，及一使該穿戴單元之該傳動軸與該運作單元之該銜接件不連動的脫離位置之間切換。The control unit includes a housing connected to the joint of the operating unit and through which the drive shaft passes, and a clutch mechanism mounted on the housing. The clutch mechanism can be switched between a linkage position in which the drive shaft of the wearable unit and the joint of the operating unit are actuated together, and a disengagement position in which the drive shaft of the wearable unit and the joint of the operating unit are not linked.

本發明之功效在於：利用該控制單元之該離合機構，能因應動作需求自由控制該穿戴單元是否與該銜接件連動，也就是能自由切換是否利用該阻尼器產生的該輔助力來輔助當下動作。因此，穿戴者能在未進行需要輔助之動作時，選擇將該離合機構切換至該脫離位置，即可在穿戴本發明省力輔助裝置的情況下，維持正常行動而不受到該輔助力影響，故因不需頻繁穿卸而更便於使用，也就當然更適合長時間穿戴。The utility of the present invention is that the clutch mechanism of the control unit can be used to freely control whether the wearable unit is linked to the joint according to the action requirements, that is, it can freely switch whether to use the auxiliary force generated by the damper to assist the current action. Therefore, when the wearer is not performing an action that requires assistance, he can choose to switch the clutch mechanism to the disengaged position, and can maintain normal actions without being affected by the auxiliary force while wearing the labor-saving auxiliary device of the present invention. Therefore, it is more convenient to use because it does not need to be frequently put on and taken off, and of course it is more suitable for long-term wear.

在本發明被詳細描述之前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that similar components are represented by the same reference numerals in the following description.

參閱圖2，為本發明省力輔助裝置之一第一實施例，本第一實施例適用於供一人體9穿戴，並包含二運作單元2、一連接於該等運作單元2且用以使該運作單元2定位於人體的穿戴單元3，及二分別安裝於該等運作單元2的控制單元4。在本第一實施例中，是以利用該穿戴單元3穿戴於該人體9之腰部，使配置於該人體9兩側之該等運作單元2得以輔助該人體9之彎腰活動的情況來說明，但實際實施時，本第一實施例並不以輔助彎腰活動的應用為限。Referring to FIG. 2 , a first embodiment of the labor-saving assisting device of the present invention is shown. The first embodiment is suitable for being worn by ahuman body 9 and comprises twooperating units 2, awearable unit 3 connected to theoperating units 2 and used to position theoperating units 2 on the human body, and twocontrol units 4 respectively mounted on theoperating units 2. In the first embodiment, thewearable unit 3 is worn on the waist of thehuman body 9 so that theoperating units 2 disposed on both sides of thehuman body 9 can assist thehuman body 9 in bending. However, in actual implementation, the first embodiment is not limited to the application of assisting bending.

同時參閱圖2與圖3，每一該運作單元2包括一本體21、一穿設於該本體21且能沿一轉軸線相對於該本體21轉動的轉輪22、一連接於該轉輪22且能與該轉輪22一同轉動的銜接件23、一與該本體21相鄰設置的阻尼器24，及一繞設於該轉輪22且遠離該轉輪22之一端連接於該阻尼器24的牽引索25。每一該運作單元2之該銜接件23能如圖4所呈現地，在一初始位置，及一帶動該轉輪22轉動而使該牽引索25施力於該阻尼器24，並使該阻尼器24產生一輔助力的作動位置之間移動。Referring to FIG. 2 and FIG. 3 , each of theoperating units 2 includes abody 21, awheel 22 that penetrates thebody 21 and can rotate relative to thebody 21 along a rotation axis, acoupling 23 that is connected to thewheel 22 and can rotate together with thewheel 22, adamper 24 that is disposed adjacent to thebody 21, and atraction cable 25 that is wound around thewheel 22 and one end of which is away from thewheel 22 and connected to thedamper 24. Thecoupling 23 of each of theoperating units 2 can move between an initial position and an actuation position in which thewheel 22 is driven to rotate so that thetraction cable 25 applies force to thedamper 24 and thedamper 24 generates an auxiliary force, as shown in FIG. 4 .

同時參閱圖2至圖4，也就是說，該運作單元2在該銜接件23被帶動而拉動該牽引索25時，即可產生一能讓該銜接件23復位的彈性恢復力。據此，只要妥善設計連結於該銜接件23的對應機構，即可藉由該彈性恢復力產生對該人體9之特定活動的輔助效果。Referring to FIGS. 2 to 4 , theoperating unit 2 can generate an elastic restoring force that can restore the connectingmember 23 when the connectingmember 23 is driven to pull thetowing rope 25. Therefore, as long as the corresponding mechanism connected to the connectingmember 23 is properly designed, the elastic restoring force can produce an auxiliary effect on the specific activities of thehuman body 9.

該穿戴單元3包括至少一適用於抵接該人體9至少一部分的接觸件31、二與該至少一接觸件31連動的傳動軸32，及二分別用以使該等運作單元2定位於該人體9之兩側的定位件39。在此要先說明的是，該至少一接觸件31在本第一實施例中，具體而言是接觸該人體9的前側面，且較佳可為一個頂抵於胸口的單件式構造，或者是如圖2所呈現之分別頂抵於雙肩前側的兩件結構。在此情況下，該等定位件39是分別連接於該等運作單元2，且較佳是因應該人體9彎腰的動作，分別定位於該人體9的雙腿。據此，在該人體9執行向前彎腰的動作時，即會在該等運作單元2係相對定位的情況下，由該至少一接觸件31帶動該等傳動軸32轉動。Thewearable unit 3 includes at least onecontact member 31 adapted to abut against at least a portion of thehuman body 9, twotransmission shafts 32 linked to the at least onecontact member 31, and twopositioning members 39 respectively used to position theoperating units 2 on both sides of thehuman body 9. It should be noted here that the at least onecontact member 31 in the first embodiment specifically contacts the front side of thehuman body 9, and is preferably a single-piece structure abutting against the chest, or a two-piece structure abutting against the front sides of both shoulders as shown in FIG. 2. In this case, thepositioning members 39 are respectively connected to theoperating units 2, and are preferably positioned on both legs of thehuman body 9 in response to the bending action of thehuman body 9. Accordingly, when thehuman body 9 performs the action of bending forward, thedriving shafts 32 are driven to rotate by the at least onecontact member 31 while theoperating units 2 are relatively positioned.

參閱圖5與圖6並配合圖2，每一該控制單元4包括一連接於該銜接件23並圍繞界定出一安裝空間410且供該傳動軸32穿設的殼體41，及一安裝於該殼體41而配置於該安裝空間410中的離合機構42。該離合機構42具有一連接於該傳動軸32的離合齒輪421、一與該離合齒輪421相鄰設置的切換片422，及一用以驅動該切換片422定位於該離合齒輪421與否的驅動模組423。其中，該切換片422具有一以一轉軸樞接於該殼體41的基部425、一自該基部425朝向該驅動模組423延伸且用以供推抵而相對於該轉軸轉動的受力部426，及一自該基部425朝向該離合齒輪421延伸，且用以可脫離地嚙合於該離合齒輪421的嚙合部427。該驅動模組423具有一用以推抵該切換片422之該受力部426的頂桿428，及一用以驅動該頂桿428的馬達429。該馬達429能在一使該頂桿428推抵該受力部426而讓該嚙合部427脫離該離合齒輪421的驅動狀態(如圖6)，及一使該頂桿428脫離該受力部426的待機狀態(如圖5)之間切換。Referring to FIG. 5 and FIG. 6 in conjunction with FIG. 2 , eachcontrol unit 4 includes ahousing 41 connected to thejoint 23 and surrounding amounting space 410 through which thedrive shaft 32 passes, and aclutch mechanism 42 mounted on thehousing 41 and disposed in themounting space 410. Theclutch mechanism 42 has aclutch gear 421 connected to thedrive shaft 32, aswitching plate 422 disposed adjacent to theclutch gear 421, and adriving module 423 for driving theswitching plate 422 to be positioned at theclutch gear 421 or not. Theswitching plate 422 has abase 425 pivotally connected to thehousing 41 by a rotating shaft, a force-bearingportion 426 extending from thebase 425 toward thedriving module 423 and used for pushing and rotating relative to the rotating shaft, and anengaging portion 427 extending from thebase 425 toward theclutch gear 421 and used for releasably engaging with theclutch gear 421. Thedriving module 423 has atop rod 428 for pushing the force-bearingportion 426 of theswitching plate 422, and amotor 429 for driving thetop rod 428. Themotor 429 can switch between a driving state (as shown in FIG. 6 ) in which thetop rod 428 pushes against the force-bearingportion 426 to allow theengaging portion 427 to disengage from theclutch gear 421, and a standby state (as shown in FIG. 5 ) in which thetop rod 428 disengages from the force-bearingportion 426.

該離合機構42能在一使該傳動軸32與該銜接件23一同作動的連動位置，及一使該傳動軸32與該銜接件23不連動的脫離位置之間切換。據此，穿戴本第一實施例的使用者，在執行特定工作而需要本第一實施例發揮輔助效果時，由於該驅動模組423之該馬達429不作動的該待機狀態時，該切換片422之該嚙合部427即是如圖5所呈現地嚙合於該離合齒輪421，於是使用者動作時透過該穿戴單元3傳遞至該等運作單元2的連動，即會藉由該銜接件23與該殼體41概為一體的連接關係，藉此構成連動關係而讓該等運作單元2確實運作，且以所述阻尼器24的輔助力來達成輔助使用者的目的。Theclutch mechanism 42 can be switched between a linkage position in which thetransmission shaft 32 and the connectingmember 23 are moved together, and a disengagement position in which thetransmission shaft 32 and the connectingmember 23 are not linked. Accordingly, when a user wearing the first embodiment needs the auxiliary effect of the first embodiment to perform a specific task, since themotor 429 of thedrive module 423 is in the standby state and is not actuated, theengaging portion 427 of theswitch plate 422 is engaged with theclutch gear 421 as shown in FIG. 5 , so that when the user moves, the linkage transmitted to theoperating units 2 through thewearable unit 3 is formed through the integral connection relationship between thecoupling 23 and thehousing 41, thereby forming a linkage relationship so that theoperating units 2 can operate effectively, and the auxiliary force of thedamper 24 is used to achieve the purpose of assisting the user.

另，若是使用者不繼續工作而需要休息時，即可操作該馬達429切換至該驅動狀態，也就是使得該嚙合部427如圖6所呈現地脫離該離合齒輪421。此時，無論使用者執行什麼動作，由於該離合齒輪421會空轉而不會與該殼體41一同轉動，故該殼體41也就不會推動所述銜接件23，因此該等運作單元2之該等阻尼器24則不會接收到外力，所以該等阻尼器24也就不會產生任何的輔助力。在該等運作單元2完全未提供輔助力的情況下，該等運作單元2則只是單純透過該穿戴單元3配置於使用者身上，但並不會影響到使用者的一般正常活動，故使用者在工作休息之餘，也就不用特別卸下本第一實施例，因而省下了許多反覆穿卸的無謂麻煩及時間耗費。In addition, if the user does not continue to work and needs to take a break, themotor 429 can be operated to switch to the driving state, that is, theengaging portion 427 is disengaged from theclutch gear 421 as shown in FIG6 . At this time, no matter what action the user performs, since theclutch gear 421 will idle and will not rotate with thehousing 41, thehousing 41 will not push thejoint 23, so thedampers 24 of theoperating units 2 will not receive external force, so thedampers 24 will not generate any auxiliary force. When theoperating units 2 do not provide any auxiliary assistance, theoperating units 2 are simply configured on the user through the wearingunit 3, but will not affect the user's normal activities. Therefore, the user does not need to remove the first embodiment when working or taking a break, thereby saving a lot of unnecessary trouble and time consumption of repeated wearing and removing.

值得特別說明的是，由於使用者穿戴本第一實施例時，大多時間都是維持在執行特定工作而需要輔助的狀態。透過本第一實施例之該馬達429係在該待機狀態時即是讓該離合機構42處於該連動位置的特性，在需要利用該等運作單元2的較長工作時間下，就不需要耗費驅動所述馬達429的電力，藉此達成節省電力的額外效果。It is worth mentioning that, since the user is wearing the first embodiment, most of the time he is in a state of performing specific tasks and requiring assistance. Themotor 429 of the first embodiment has the characteristic of making theclutch mechanism 42 in the linkage position when in the standby state, and when theoperating units 2 are required to work for a longer time, it is not necessary to consume the power to drive themotor 429, thereby achieving the additional effect of saving power.

參閱圖7與圖8，為本發明省力輔助裝置之一第二實施例，本第二實施例與該第一實施例的差別在於：本第二實施例之該控制單元4還包括一資訊連接於該離合機構42的調整機構43。其中，該穿戴單元3還包括一適用於作為該人體9站立而未彎腰時之位置參考的基準件(圖中未標示)，該調整機構43具有一用以感測該基準件相對於一零點值之一傾斜角度的感測器431、一資訊連接於該感測器431及該離合機構42的主控模組432，及一用以調整一角度之臨界值θt的設定件433。在本第二實施例中，該感測器431為一電位感應器，而該基準件可為該穿戴單元3上會隨人體9之彎腰動作移動的任何部位，只要便於該感測器431利用電位感測機制確實感測位移量即可。Referring to FIG. 7 and FIG. 8 , a second embodiment of the labor-saving auxiliary device of the present invention is shown. The difference between the second embodiment and the first embodiment is that thecontrol unit 4 of the second embodiment further includes anadjustment mechanism 43 connected to theclutch mechanism 42. Thewearable unit 3 further includes a reference piece (not shown in the figure) suitable for being used as a reference for the position of thehuman body 9 when standing without bending. Theadjustment mechanism 43 has asensor 431 for sensing a tilt angle of the reference piece relative to a zero point value, amain control module 432 connected to thesensor 431 and theclutch mechanism 42, and asetting piece 433 for adjusting a critical value θt of an angle. In the second embodiment, thesensor 431 is a potential sensor, and the reference piece can be any part of thewearable unit 3 that moves with the bending movement of thehuman body 9, as long as thesensor 431 can use the potential sensing mechanism to accurately sense the displacement.

為了能讓本第二實施例更能配合穿戴者的動作習慣，只要預先透過該設定件433設定適當的該臨界值θt，該主控模組432就可以用以在該傾斜角度，也就是穿戴者彎腰的角度大於該臨界值θt時，使該離合機構42切換至該連動位置，即藉此使得該等運作單元2得以開始提供輔助力，以輔助穿戴者的彎腰動作。據此，穿戴者即可自由依照動作習慣，使得本第二實施例在較佳的位置點開始提供輔助，於是得以更精準地因應穿戴者的動作，也能更有效率地發揮輔助效果。In order to make the second embodiment more compatible with the wearer's movement habits, as long as the appropriate critical value θt is set in advance through thesetting member 433, themain control module 432 can be used to switch theclutch mechanism 42 to the linkage position when the tilt angle, that is, the angle of the wearer's bending waist is greater than the critical value θt, so that theoperating units 2 can start to provide auxiliary force to assist the wearer's bending waist movement. Accordingly, the wearer can freely follow the movement habits, so that the second embodiment starts to provide assistance at a better position point, so that the wearer's movement can be more accurately responded to and the auxiliary effect can be more efficiently exerted.

綜上所述，本發明省力輔助裝置，除了藉由該等運作單元2來發揮輔助效果的基本功能，還能利用所述離合機構42的切換，使得穿戴者在休息時，不會受到該等運作單元2的輔助力而能維持正常動作，且更能透過該調整機構43的配置，進一步配合穿戴者的動作習慣調整，藉此更精準地因應穿戴者的動作，適時提供相對較有效率的輔助。因此，確實能達成本發明之目的。In summary, the labor-saving assistive device of the present invention, in addition to the basic function of the assistive effect by theoperating units 2, can also utilize the switching of theclutch mechanism 42 so that the wearer will not be assisted by theoperating units 2 when resting and can maintain normal movements, and can further adjust to the wearer's movement habits through the configuration of theadjustment mechanism 43, thereby more accurately responding to the wearer's movements and providing relatively efficient assistance in a timely manner. Therefore, the purpose of the present invention can be achieved.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above is only an example of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application and the content of the patent specification of the present invention are still within the scope of the present patent.
