此外，如图1、图2所示，本例中底撑架2的前端部、后端部分别与前支架11的下部和后支架12转动连接，后撑架3位于两侧的后支架12之间，且与两侧的后支架12转动连接；具体地：后撑架3包括：中杆30，中杆30沿推车上下方向延伸；第一上连杆31和第二上连杆32，第一上连杆31和第二上连杆32的一端分别与中杆30的上端部转动连接，另一端分别与两侧的后支架12转动连接；第一下连杆33和第二下连杆34，第一下连杆33和第二下连杆34的一端分别与中杆30的下部转动连接，另一端分别与两侧的后支架12转动连接；滑块35，其沿着中杆30的延伸方向能够滑动地设置在中杆30上；第一斜连杆36、第二斜连杆37，第一斜连杆36、第二斜连杆37的下端分别与第一下连杆33和第二下连杆34转动连接，上端与滑块35转动连接（本例中，后撑架3设置有固定连接于中杆30底端部的用于拉动后撑架3收折的拉手38）。底撑架2为十字结构底撑架2，包括相互交叉并在交叉处相转动连接的第一底杆21和第二底杆22，第一底杆21和第二底杆22的前部分别与两侧的前支架11转动连接；第一底杆21和第二底杆22的后部分别与两侧的后支架12转动连接。In addition, as shown in Figures 1 and 2, the front end and rear end of the bottom bracket 2 in this example are rotatably connected to the lower part of the front bracket 11 and the rear bracket 12 respectively, and the rear bracket 3 is located on the rear bracket 12 on both sides. Between, and with the rear bracket 12 on both sides of the rotation connection; Specifically: the rear bracket 3 includes: the middle rod 30, the middle rod 30 extends along the up and down direction of the cart; the first upper link 31 and the second upper link 32 One end of the first upper link 31 and the second upper link 32 are rotatably connected with the upper end of the middle rod 30 respectively, and the other ends are rotatably connected with the rear brackets 12 on both sides respectively; the first lower link 33 and the second lower link Connecting rod 34, one end of the first lower connecting rod 33 and the second lower connecting rod 34 are rotatably connected with the bottom of the middle rod 30 respectively, and the other ends are respectively rotatably connected with the rear brackets 12 on both sides; The extension direction of the rod 30 can be slidably arranged on the middle rod 30; the first oblique connecting rod 36, the second oblique connecting rod 37, and the lower ends of the first oblique connecting rod 36 and the second oblique connecting rod 37 are connected with the first lower connecting rod respectively. Rod 33 and second lower connecting rod 34 are rotationally connected, and the upper end is rotationally connected with slide block 35 (in this example, rear support frame 3 is provided with and is used for pulling rear support frame 3 folds that is fixedly connected at the bottom end of middle rod 30 handle 38). The bottom support frame 2 is a cross structure bottom support frame 2, including a first bottom bar 21 and a second bottom bar 22 that intersect each other and are rotatably connected at the intersection. The front parts of the first bottom bar 21 and the second bottom bar 22 are respectively It is rotatably connected with the front brackets 11 on both sides; the rear parts of the first bottom bar 21 and the second bottom bar 22 are respectively rotatably connected with the rear brackets 12 on both sides.
如图1所示，当推车车架处于展开状态下，锁定机构锁定车架，前支架11和后支架12相互展开并分别通过前轮组件100和后轮组件200撑立在地面上，后支架12及其上端部固定连接的坐杆120与前支架11、连撑杆13相互展开；座杆120与前支架11的连接处、连撑杆13与后支架12连接处（处于第一位置W1）分别位于连撑杆13与前支架11连接处的前下方，连撑杆13与后支架12连接处位于座杆120与前支架11的连接处的后下方，且连撑杆13与水平方向之间的夹角为80-90°。As shown in Figure 1, when the stroller frame is in the unfolded state, the locking mechanism locks the frame, the front bracket 11 and the rear bracket 12 are mutually deployed and stand on the ground through the front wheel assembly 100 and the rear wheel assembly 200 respectively, and the rear The seat post 120 fixedly connected to the support 12 and its upper end and the front support 11 and the connecting strut 13 are mutually expanded; W1) are respectively located at the front and lower part of the connection between the connecting strut 13 and the front bracket 11, and the connection between the connecting strut 13 and the rear bracket 12 is located at the rear and lower part of the connection between the seatpost 120 and the front bracket 11, and the connecting strut 13 and the horizontal The angle between the directions is 80-90°.
结合图1至图4，当推车车架折叠时，锁定机构解锁，抓住后撑架3上的拉手38向上运动，后撑架3的中杆30向上运动带动后撑架3各部件从车架的两侧向中间靠拢收折，即带动两侧的后支架12从车架的两侧向中间靠拢，并带动底撑架2和侧支架1中的其他部件向中间靠拢，在抓住后撑架3上的拉手38向上运动带动后支架12向中间靠拢的同时，也会对后支架12的下端部施加一个向后上方翻转的力，即，坐杆120（坐杆与后支架为同一部件）会相对前支架11发生转动，由于后支架12是即转动又滑动的连接在连撑杆13上的，则后支架12转动时，会沿连撑杆13向上滑动（一直滑至第二位置W2，以避免对收折产生干涉），即，后支架12及其上端部的坐杆120与前支架11逐渐转动靠拢，至此，即完成了整个推车的收折过程，车架转换至折叠状态。1 to 4, when the cart frame is folded, the locking mechanism is unlocked, and the handle 38 on the rear bracket 3 is grasped to move upward, and the middle rod 30 of the rear bracket 3 moves upward to drive the components of the rear bracket 3 from The two sides of the vehicle frame are folded closer to the middle, that is, the rear brackets 12 on both sides are moved closer to the middle from the two sides of the vehicle frame, and the bottom bracket 2 and other components in the side bracket 1 are moved closer to the middle. When the handle 38 on the rear bracket 3 moves upwards to drive the rear bracket 12 to move closer to the middle, it will also apply a force to the lower end of the rear bracket 12 to turn backwards and upwards, that is, the seat post 120 (the seat post and the rear support are The same part) will rotate relative to the front bracket 11. Since the rear bracket 12 is connected to the connecting strut 13 by rotating and sliding, when the rear bracket 12 rotates, it will slide upwards along the connecting strut 13 (sliding all the way to the first Two positions W2, to avoid interference with folding), that is, the seat post 120 of the rear bracket 12 and its upper end and the front bracket 11 are gradually rotated closer, so far, the folding process of the entire cart has been completed, and the frame conversion to the collapsed state.
如图4所示，推车车架处于折叠状态下，前轮组件100、后轮组件200沿前支架11延伸方向相互远离；侧支架1、底撑架2、后撑架3中各杆件沿着前支架11延伸方向延伸且在左右方向紧密靠拢。As shown in Figure 4, when the cart frame is in the folded state, the front wheel assembly 100 and the rear wheel assembly 200 are away from each other along the direction in which the front bracket 11 extends; They extend along the extension direction of the front bracket 11 and are close together in the left and right directions.
综上，本实用新型的儿童推车，相比传统的推车，后支架与坐杆其为一根杆弯折成型，一根杆兼具了传统推车的后支架与坐杆的功能，杆件减少，也减少了车架折叠过程杆件之间的干涉情况，并且采用底撑架与后撑架使得推车从前后左右方向可实现一拎即折，折叠后，车身修长，各部件之间紧密靠拢且工整排列，体积小，特别适合在狭长的空间存放；此外，将前轮组件安装在推杆的最下端，使推杆兼具了传统推车中前轮支架的功能，推车整体杆件进一步减少，避免过多的杆件之间的过多的连接关系；通过连撑在前支架与后支架之间的连撑杆，使得车架保持很好的刚性，整体结构更加稳固，其负重后不会内收。To sum up, compared with the traditional stroller, the children’s stroller of the present utility model has the rear bracket and the seat post formed by bending one rod, and one rod has both the functions of the rear bracket and the seat post of the traditional stroller. The reduction of rods also reduces the interference between the rods during the folding process of the frame, and the bottom bracket and rear bracket are used to enable the cart to be folded from the front, rear, left, and right directions. After folding, the body is slender and the components are They are close together and neatly arranged, small in size, especially suitable for storage in narrow and long spaces; in addition, the front wheel assembly is installed at the bottom of the push rod, so that the push rod has the function of the front wheel bracket in the traditional cart, and push The overall rods of the car are further reduced to avoid excessive connections between too many rods; through the connecting rods between the front bracket and the rear bracket, the frame maintains good rigidity, and the overall structure is more rigid. Stable, it does not retract under load.
