嬰幼兒出生後因還無法自行走路，多半需由家長抱著；長時間外出時為減輕家長雙手負擔，多半會讓嬰兒坐在嬰兒手推車中。然在搭乘汽車、大眾運輸工具或進入擁擠場所時，家長還是要將嬰兒抱起並收折嬰兒手推車，才能繼續後續行程；由於家長帶嬰孩兒出門多半還要攜帶奶粉、奶瓶、保溫瓶、尿布、紙巾……等大量嬰兒用品，一手環抱嬰兒再肩揹嬰兒用品背包，還要展收嬰兒手推車，對於家長來說勢必手忙腳亂；加上現有嬰兒手推車展收時完全須要依賴家長的力量，若家長是瘦弱的媽媽，常面臨展收不順暢、須要數次才能到定位，或須耗費很久時間，甚至還會有展收失敗的惱人狀況。顯見，現有手動式嬰兒手推車之展收結構，甚不理想。縱使有業者開發出電動展收式嬰兒手推車，但其售價高，特別是為了達到電動展收，馬達須具一定程度的出力，導致其體積大、重量重，電池也連帶無法輕薄化，更且，其於電力耗盡時完全無法展收作動，甚為令人詬病。 After birth, infants are still unable to walk on their own, and most of them need to be held by their parents; in order to reduce the burden on parents' hands when going out for a long time, most of them will let the infant sit in a stroller. However, when taking a car, public transportation or entering a crowded place, parents still have to pick up the baby and fold the baby stroller before continuing the follow-up journey; since parents take the baby out, most of them also carry milk powder, feeding bottles, thermos bottles, and diapers , paper towels, etc., and a large number of baby products, such as holding the baby with one hand, carrying the baby product backpack on the shoulder, and unfolding and closing the baby trolley, it is bound to be a mess for the parents; in addition, the existing baby trolley needs to be completely dependent on the power of the parents, if the parents It is a thin mother who often faces the annoying situation of unsmooth opening and closing, which takes several times to locate, or takes a long time, and even fails to open and close. Obviously, the unfolding and retracting structure of the existing manual baby stroller is far from ideal. Even if the industry develops Electric retractable baby stroller, but its price is high, especially in order to achieve electric retractable, the motor must have a certain degree of output, resulting in its large size and heavy weight, and the battery cannot be thinned. When it is exhausted, it is completely unable to expand and retract actions, which is very criticized.

該蓄力單元2，鄰設於該電控單元1旁，該蓄力單元2包括有一底座21，該底座21頂部凹設有一空間211，且空間211中設置有一固定部212；另該底座21外側緣面設置有側蝸齒213，該側蝸齒213能用以與該電控單元1之蝸齒142囓合；該底座21之上方設置有一頂座22，該頂座22下方略靠外緣處設置有一結合部221，且該頂座22之頂面設置有一連動軸222；前述空間211內設置有一捲簧23，該捲簧23兩端分別為內端部231與外端部232，其中該內端部231連結到底座21的固定部212處，至於外端部232則連結到頂座22的結合部221處；另該頂座22之連動軸222處，套接至一連動元件24的一端，該連動元件24包括有一彈簧241，該彈簧241外部套設有一套管242，至於該連動元件24相對於連動軸222的另一端，連接有一推軸243。 The power storage unit 2 is adjacent to the electric control unit 1, and the power storage unit 2 includes a base 21, a space 211 is recessed on the top of the base 21, and a fixing part 212 is arranged in the space 211; in addition, the base 21 The outer edge surface is provided with side worm teeth 213, and the side worm teeth 213 can be used for meshing with the worm teeth 142 of the electric control unit 1; A joint part 221 is provided slightly near the outer edge, and a linkage shaft 222 is provided on the top surface of the top seat 22; a coil spring 23 is provided in the aforementioned space 211, and the two ends of the coil spring 23 are the inner end 231 and the outer end respectively. part 232, wherein the inner end 231 is connected to the fixed part 212 of the base 21, and the outer end 232 is connected to the joint part 221 of the top seat 22; and the connecting shaft 222 of the top seat 22 is sleeved to a One end of the linkage element 24 , the linkage element 24 includes a spring 241 , and a sleeve 242 is sleeved on the outside of the spring 241 . As for the other end of the linkage element 24 opposite to the linkage shaft 222 , a push shaft 243 is connected.

再請配合第三圖與第四圖，係本案於初始還未進行蓄力之狀態，由於感應開關17、電池10和馬達11間的電性迴路為通路，馬達11啟動，驅使出力軸111和滑動軸13轉動，連帶使蝸桿14轉動，蝸桿14將藉蝸齒142囓合至側蝸齒213使底座21被轉動；假設頂座22受制於嬰兒手推車未進行收折變化而無法旋動，將使捲簧23被逐漸扭緊，直到捲簧23被扭緊到底後，底座21無法再旋轉，致使蝸桿14藉滑動軸13朝向擋板16端滑移，彈性元件15被壓縮，最後使擋環143碰觸並壓按感應元件171，此時，感應開關17、電池10和馬達11間的電性迴路將改變形成斷路，蓄力備用程序完成，捲簧23維持被扭緊狀態，即如第五圖所示。 Please cooperate with the third picture and the fourth picture. This case is in the initial state of power storage. Since the electrical circuit between the sensor switch 17, the battery 10 and the motor 11 is a path, the motor 11 starts to drive the output shaft 111 and The sliding shaft 13 rotates, and the worm screw 14 rotates, and the worm screw 14 will engage the side worm gear 213 through the worm gear 142 to rotate the base 21; if the top seat 22 cannot rotate due to the fact that the baby stroller is not folded, it will make the The coil spring 23 is gradually tightened until the coil spring 23 is tightened to the end, the base 21 can no longer rotate, causing the worm 14 to slide towards the end of the baffle plate 16 through the sliding shaft 13, the elastic element 15 is compressed, and finally the baffle ring 143 Touch and press the inductive element 171, at this moment, the electrical circuit between the inductive switch 17, the battery 10 and the motor 11 will change to form an open circuit, the power storage backup procedure is completed, and the coil spring 23 remains in a tightened state, that is, as the fifth As shown in the figure.

若當本案要應用於形成一輔助推力或拉力時，將該嬰兒手推車之輔助展收裝置8裝設於具展收功能之嬰兒手推車9的車架處，請參考第六圖，本案之推軸243配接於連桿91一端，該連桿91另一端軸接到一曲軸92處，若嬰兒手推車9原本呈收合狀態，且經家長解開展收變化之安全鎖定，嬰兒手推車9車架將由收合轉換成可以展開的自由動作狀態，然受制於馬達11內部提供咬合作用，連帶使出力軸111、滑動軸13、蝸桿14與底座21皆呈現鎖定狀態，然嬰兒手推車9與推軸243端呈現能自由形變之狀態；是以，原本被旋緊的捲簧23得以釋放蓄力，連動頂座22轉動，提供連動元件24產生一相對於嬰兒手推車9之作用力，輔助嬰兒手推車9加速展開，提高展開成功率與縮短時間，以利使用。至於每次完成輔助展收、捲簧23已釋放蓄力後，由於該蝸桿14之蝸齒142處於自由狀態，加上蝸桿14一端配置有彈性元件15，因此蝸桿14會受到彈性元件15的作用力推回歸位，同時間擋環143離開感應元件171，如是，感應開關17、電池10和馬達11間的電性迴路將改變形成通路，並再次令該馬達11作動，接續再自動進行旋緊捲簧23之蓄力備用程序，以等待下一次的輔助展收作用。 If this case is to be applied to form an auxiliary pushing or pulling force, the auxiliary unfolding device 8 of the baby stroller is installed on the frame of the baby stroller 9 with the function of unfolding and retracting, please refer to the sixth figure, the push shaft of this case 243 matching Connected to one end of the connecting rod 91, the other end of the connecting rod 91 is connected to a crankshaft 92. If the baby stroller 9 is originally in a folded state, and the safety lock of the opening and closing change is released by the parents, the baby stroller 9 frame will be folded Converted to a free movement state that can be unfolded, but subject to the engagement provided by the motor 11, the output shaft 111, the sliding shaft 13, the worm 14 and the base 21 are all in a locked state, but the baby trolley 9 and the end of the push shaft 243 appear to be able to move. The state of free deformation; therefore, the originally tightened coil spring 23 can release the power storage, and the top seat 22 is rotated to provide the linkage element 24 to generate a force relative to the baby trolley 9, and assist the baby trolley 9 to accelerate and expand. Expand the success rate and shorten the time to facilitate use. As for each time the auxiliary deployment is completed and the coil spring 23 has released the power storage, since the worm gear 142 of the worm 14 is in a free state, and the elastic element 15 is disposed at one end of the worm 14, the worm 14 will be affected by the elastic element 15 Push it back to the original position, and at the same time, the time stop ring 143 leaves the sensing element 171. If so, the electrical circuit between the sensing switch 17, the battery 10, and the motor 11 will change to form a path, and the motor 11 will be activated again, and then it will be automatically tightened again. The power storage standby program of the coil spring 23 is to wait for the next auxiliary unfolding and retracting effect.

又如第七圖，若嬰兒手推車9原本呈展開狀態，且經家長解開鎖定後，依據上一段所述之原理，經蓄力後的輔助展收裝置8亦會主動產生一作用力，輔助嬰兒手推車9加速完成至收合狀態。相同的，完成該次輔助展收作用後，即會再次自動進行旋緊捲簧23之蓄力備用程序，以等候下一次的輔助展收需求。 As shown in Figure 7, if the baby stroller 9 is originally in the unfolded state, and after the parent unlocks the lock, according to the principle described in the previous paragraph, the auxiliary unfolding device 8 after the power storage will also actively generate a force to assist The baby stroller 9 is accelerated and completed to the folded state. Similarly, after completing the auxiliary unfolding action, the power storage backup procedure of tightening the coil spring 23 will be automatically carried out again, so as to wait for the next auxiliary unfolding demand.
