Description
本發明係有關一種煞車機構,特別是指具有操作省力功能的一種座椅高低調整裝置的煞車機構。 The present invention relates to a brake mechanism, and more particularly to a brake mechanism having a seat height adjustment device having a function of saving effort.
關於座椅的高低調整裝置,例如安裝於汽車的座椅上的高低調整裝置,或例如安裝於按摩椅、輪椅等的高低調整裝置,主要用來調整座椅的高低,以適合不同身高的使用者乘座。 The height adjustment device for the seat, such as a height adjustment device mounted on the seat of the automobile, or a height adjustment device such as a massage chair or a wheelchair, is mainly used to adjust the height of the seat to suit different heights. Take the seat.
座椅內設置有升降機構,高低調整裝置設置於座椅一側且連接於升降機構,一控制把則連接於高低調整機構,以在使用者向上扳動或向下推動控制把時,能經由高低調整裝置而控制升降機構升降,進而達到調整座椅高低的目的。 A lifting mechanism is arranged in the seat, the height adjusting device is disposed on one side of the seat and connected to the lifting mechanism, and a control lever is connected to the high and low adjusting mechanism to enable the user to pull up or push the control handle downwards The height adjustment device controls the lifting mechanism to lift and lower, thereby achieving the purpose of adjusting the height of the seat.
高低調整裝置包括彼此同軸配置的一離合機構和一煞車機構,所述控制把則連接於離合機構。其中,現有離合機構包含:一驅動構件(與煞車機構共用)、設置於驅動構件之凹槽內的一輸入部件和多數第一控制組件、以及對應驅動構件罩覆的一罩體,並以控制把控制輸入部件轉動;如圖1所示,現有煞車機構則包含:一煞車環A1、設置於煞車環內的一輸出部件A2和多數第二控制組件A3、以及蓋覆於煞車環的驅動構件(與離合機構共用),其中,驅動構件突出有多數驅動腳A4(呈三角柱形),各驅動腳伸入於任相鄰二第二控制組件之間。 The height adjustment device includes a clutch mechanism and a brake mechanism that are coaxially arranged with each other, and the control handle is coupled to the clutch mechanism. Wherein, the existing clutch mechanism comprises: a driving member (shared with the braking mechanism), an input member disposed in the groove of the driving member, a plurality of first control components, and a cover corresponding to the driving member, and is controlled The control input member is rotated; as shown in FIG. 1 , the existing brake mechanism includes: a brake ring A1, an output member A2 disposed in the brake ring, a plurality of second control assemblies A3, and a drive member covering the brake ring. (shared with the clutch mechanism), wherein the driving member protrudes from a plurality of driving legs A4 (in a triangular prism shape), and each driving leg protrudes between any two adjacent second control components.
高低調整裝置在操作上係以控制把經由離合機構帶動驅動構件轉動。 The height adjustment device is operative to control the rotation of the drive member via the clutch mechanism.
如圖1所示的現有煞車機構,驅動構件帶同驅動腳A4一起轉動後,各驅動腳將會接觸於各第二控制組件中的其中一滾軸A31而產生一接觸點A;各驅動腳經由接觸點A推動各滾軸,各滾軸A31則接觸於輸出部件周緣的凸齒(以下簡稱受動凸齒A21)而產生一接觸點B,使各滾軸藉由接觸點B囓合於受動凸齒而利於帶動;因此,當繼續轉動控制把時,將能帶動輸出部件A2一起轉動;由於輸出部件的一軸端係與安裝於汽車座椅、按摩椅或輪椅等內的升降機構囓接,因此能經由升降機構控制座椅、按摩椅或輪椅進行高低調整。 As shown in FIG. 1 , after the driving member belt rotates together with the driving leg A4 , each driving leg will contact one of the second control components to generate a contact point A; each driving leg; Each roller is pushed through the contact point A, and each roller A31 contacts a convex tooth (hereinafter referred to as a driven convex tooth A21) on the periphery of the output member to generate a contact point B, so that each roller is engaged with the driven convex by the contact point B. The teeth are favorable for driving; therefore, when the control handle is continuously rotated, the output member A2 can be driven to rotate together; since one axial end of the output member is engaged with a lifting mechanism mounted in a car seat, a massage chair or a wheelchair, etc., The height can be adjusted by controlling the seat, massage chair or wheelchair via the lifting mechanism.
惟,現有煞車機構在實際操作上,卻會因為驅動腳A4係以斜面進行驅動,且受動凸齒A21又以不規則面來受動,因此會有費力的缺失,詳如下述:假設操作控制把轉動後,造成驅動構件轉動的力矩為Ml。 However, in the actual operation, the existing brake mechanism is driven by the inclined surface of the driving foot A4, and the driven convex tooth A21 is moved by the irregular surface, so there is a laborious lack, as follows: Assume the operation control After the rotation, the moment causing the driving member to rotate is M1.
驅動腳A4施加於接觸點A的操作力設為Fl(驅動腳推動滾軸A31的方向),從Fl到輸出部件的旋轉軸心X之間的距離為Ll(力臂),則:Ml=Fl*Ll。 The operating force applied to the contact point A by the driving foot A4 is set to F1 (the direction in which the driving foot pushes the roller A31), and the distance from F1 to the rotational axis X of the output member is L1 (force arm), then: Ml= Fl * Ll.
滾軸A31施加於接觸點B的操作力設為Fp(滾軸推動受動凸齒A21的方向),從Fp到上述旋轉軸心X的距離為Lp(力臂),則Fp對受動凸齒所提供的力矩Mp=Fp*Lp。 The operating force applied to the contact point B by the roller A31 is Fp (the direction in which the roller pushes the driven convex tooth A21), and the distance from the Fp to the rotational axis X is Lp (force arm), and Fp is applied to the driven convex tooth. The torque provided is Mp = Fp * Lp.
由於Fl>Fp(Fp=Flcosθ,θ角度越大則cosθ越趨近於0),又Ll>Lp,所以Ml>>Mp。 Since Fl>Fp(Fp=Flcosθ, the larger the θ angle is, the closer cosθ is to 0), and L1>Lp, so Ml>>Mp.
換言之,當操作控制把施力而造成力矩Ml時,實際會傳遞到受動凸齒A21上的力矩Mp將會遠小於Ml,因此導致使用者在操作控制把時會更加費力,早為人所詬病已久。 In other words, when the operation control applies a force to cause the moment M1, the moment Mp actually transmitted to the driven convex tooth A21 will be much smaller than M1, thus causing the user to be more laborious when operating the control handle, which is ill for a long time. Long time.

Assume that after the operation control is rotated, the torque causing the drive disc 1 to rotate is M1.
驅動鍵15施加於接觸點A的操作力設為Fl(驅動鍵15推動滾動圓軸53的方向),從Fl到輸出部件7的旋轉軸心X之間的距離為Ll(力臂),則:Ml=Fl*Ll。 The operating force applied to the contact point A by the drive key 15 is set to F1 (the direction in which the drive key 15 pushes the rolling circular shaft 53), and the distance from F1 to the rotational axis X of the output member 7 is L1 (force arm). :Ml=Fl * Ll.
滾動圓軸53施加於接觸點B的操作力設為Fp(滾動圓軸53經由接觸彈性墊體511而推動受動鍵72的方向),從Fp到上述旋轉軸心X的距離為Lp(力臂),則Fp對受動鍵72所提供的力矩Mp=Fp*Lp。 The operating force applied to the contact point B by the rolling circular shaft 53 is Fp (the direction in which the rolling circular shaft 53 pushes the driven key 72 via the contact elastic pad body 511), and the distance from the Fp to the above-described rotating shaft center X is Lp (force arm) ), then the torque provided by Fp to the driven key 72 is Mp = Fp * Lp.
由於Fl≒Fp(Fp=Flcosθ,θ角度小而使cosθ趨近於1),又Ll≒Lp,所以Ml≒Mp。 Since Fl ≒ Fp (Fp = Flcos θ, θ angle is small and cos θ approaches 1), and L1 ≒ Lp, Ml ≒ Mp.
如此一來,當操作控制把施力而造成力矩Ml時,與實際傳遞到受動鍵72上的力矩Mp相差不大,因此,使用者所施加的力較能確實傳遞,也就是使用者在操作控制把時具有較為省力的效果。 In this way, when the operation control applies a force to cause the moment M1, the torque Mp actually transmitted to the driven key 72 is not much different. Therefore, the force applied by the user can be surely transmitted, that is, the user is operating. The control has a relatively labor-saving effect.
此外,如圖7和圖8所示則為本發明中的另一種彈性件:彈性襯套52,彈性襯套52可套接於受動鍵72,以具有較前述彈性件51更易於安裝的效果。彈性襯套52具有彼此相對且彼此平行的二彈性墊體521,各彈性墊體521亦具有彼此相對且彼此平行的二第二平面部(未標示元件符號),於本實施例中,各彈性墊體521亦以矩形體狀為例進行說明。 In addition, as shown in FIG. 7 and FIG. 8 , it is another elastic member in the present invention: an elastic bushing 52 , and the elastic bushing 52 can be sleeved on the driven key 72 to have an easier installation effect than the foregoing elastic member 51 . . The elastic bushing 52 has two elastic pad bodies 521 which are opposite to each other and parallel to each other, and each of the elastic pad bodies 521 also has two second planar portions (not labeled with reference numerals) which are opposite to each other and are parallel to each other. In this embodiment, each elastic body The pad body 521 is also described by taking a rectangular shape as an example.
各彈性襯套52係對應各受動鍵72分別套接,使各彈性襯套52的二彈性墊體521能以其第二平面部對應各受動鍵72的二第一平面部721分別貼靠,如此達到與前述彈性件51相同的效果。 Each of the elastic bushings 52 is sleeved corresponding to each of the driven keys 72, so that the two elastic pad bodies 521 of the elastic bushings 52 can be respectively abutted against the two first plane portions 721 of the respective driven keys 72 by the second planar portion thereof. This achieves the same effect as the aforementioned elastic member 51.
綜上所述,本發明相較於先前技術係具有以下功效:藉由驅動鍵15能以其第二平面部151推動滾動圓軸53,且受動鍵72又能以其第一平面部721被滾動圓軸53間接帶動,使來自於使用者所施加的力都能夠確實傳遞,如此而讓使用者在操作控制煞車機構500轉動時,能具有較為省力的效果,也就是使用者能夠輕鬆進行座椅高度的調整。 In summary, the present invention has the following effects as compared with the prior art: the rolling circular shaft 53 can be pushed by the second flat portion 151 by the driving key 15, and the driven key 72 can be replaced by the first flat portion 721 thereof. The rolling circular shaft 53 is indirectly driven, so that the force applied from the user can be reliably transmitted, so that the user can have a labor-saving effect when the operation control braking mechanism 500 rotates, that is, the user can easily perform the seat. The height of the chair is adjusted.
此外,本發明還具有其它功效:藉由彈性墊體511、521亦具有二平面部,且彈性墊體511、521的二平面部係分別貼靠於受動鍵72的二第一平面部721,滾動圓軸53則接觸並推動於彈性墊體511、521的平面部,如此以具有更佳的省力效果。藉由改以彈性墊體511、521取代彈簧,以在將動作組件5安裝於所述間隔空間S內時,能避免發生彈簧在安裝中不慎彈出的問題,因此具有易於安裝的效果。藉由驅動鍵15係以一體沖製並彎折成型的方式形成於驅動盤1,以具有比現有三角形驅動腳(參圖1)更易於製造的效果。 In addition, the present invention has other functions: the elastic pad bodies 511 and 521 also have two planar portions, and the two planar portions of the elastic pad bodies 511 and 521 are respectively abutted against the two first planar portions 721 of the driven key 72. The rolling circular shaft 53 is in contact with and pushed to the flat portion of the elastic pad bodies 511, 521, so as to have a more labor-saving effect. By replacing the spring with the elastic pad bodies 511, 521, when the action assembly 5 is mounted in the space S, the problem that the spring is inadvertently ejected during installation can be avoided, and thus the effect of easy installation is obtained. The driving key 15 is formed on the driving disk 1 by integral punching and bending molding to have an effect of being easier to manufacture than the conventional triangular driving leg (refer to FIG. 1).
