当然，推杆3的下部、座杆4的后部、撑杆71的后部这三个部件也可以分别转动地连接在滑动件6上，也可以将这三个部件中的两个部件转动连接，再将第三个部件与前两个部件中的至少一个部件转动地连接在滑动件6上，还可以将座杆4的后部单独枢轴连接在滑动件6上，再将撑杆71的后部与推杆3的下部转动连接，然后再将撑杆71的后部或推杆3的下部转动地连接在滑动件6上，以上方式均可使得滑动件6沿后支架2上下滑动时，带动推杆3的下部、座杆4的后部以及撑杆71的后部沿后支架2相应地上下滑动。Certainly, these three parts of the bottom of push rod 3, the rear part of seatpost 4, the rear part of strut 71 also can be connected on the slider 6 in a rotational manner respectively, also can rotate two parts in these three parts connection, and then the third part is rotationally connected to at least one of the first two parts on the slider 6, and the rear part of the seatpost 4 can also be pivotally connected to the slider 6 separately, and then the strut The rear part of 71 is rotationally connected with the lower part of the push rod 3, and then the rear part of the strut 71 or the lower part of the push rod 3 is rotationally connected to the slider 6. The above methods can make the slider 6 go up and down along the rear bracket 2 When sliding, the lower part of the push rod 3 , the rear part of the seatpost 4 and the rear part of the strut 71 are driven to slide up and down correspondingly along the rear bracket 2 .
该推车车架的锁定机构可为设置于滑动件6与后支架2之间的锁定件（图中未示出），通过将滑动件6与后支架2锁定在一起而使得推杆3、座杆4及撑杆71相对后支架2固定，从而使得推车车架处于稳定的展开状态。The locking mechanism of the stroller frame can be a lock (not shown) arranged between the slider 6 and the rear bracket 2, by locking the slider 6 and the rear bracket 2 together so that the push rod 3, The seat post 4 and the strut 71 are fixed relative to the rear bracket 2, so that the stroller frame is in a stable unfolded state.
该推车车架还包括靠背杆组件9，靠背杆组件9可沿推车车架的左右方向收折地设于两侧的侧支架100之间，靠背杆组件9的下部可沿后支架2的长度延伸方向滑动且可相对后支架2转动地设于后支架2上。设置时，可将靠背杆组件9的下部枢轴连接在滑动件6上或座杆4的后部上。The cart frame also includes a backrest rod assembly 9, which can be folded along the left-right direction of the cart frame and is arranged between the side brackets 100 on both sides, and the lower part of the backrest rod assembly 9 can be arranged along the rear bracket 2. The length extension direction slides and is arranged on the rear support 2 so as to be rotatable relative to the rear support 2 . In arrangement, the lower portion of the back bar assembly 9 may be pivotally connected to the slider 6 or to the rear of the seat post 4 .
两侧推杆3的上部分别枢轴连接有推把杆10，两侧的推把杆10相邻的端部相枢轴连接，在两侧的侧支架100沿左右反向靠拢时，两侧的推把杆10相互转动而收拢。The upper parts of the push rods 3 on both sides are respectively pivotally connected with push handle bars 10, and the adjacent ends of the push handle bars 10 on both sides are pivotally connected. The push handle bar 10 is rotated mutually and draws in.
推车车架的后部还设有后附撑组件8，后附撑组件8可沿左右方向收折地设于两侧的后支架2之间，其结构可采用本领域内常用的后撑结构，此处不再赘述。The rear part of the stroller frame is also provided with a rear support assembly 8, which can be folded in the left and right directions between the rear brackets 2 on both sides, and its structure can adopt the commonly used back support in this field. structure, which will not be repeated here.
该推车车架在展开使用时，参见图1、图3及图4所示，锁定机构锁定，滑动件6相对后支架2固定，两侧的侧支架100通过撑杆组件7和后附撑组件8而沿左右方向展开，同时前支架1与后支架2在撑杆组件7和座杆4的作用下而沿前后方向撑开，扶手杆5支撑在推杆3与前支架1之间。When the cart frame is unfolded and used, as shown in Fig. 1, Fig. 3 and Fig. 4, the locking mechanism is locked, the slider 6 is fixed relative to the rear bracket 2, and the side brackets 100 on both sides pass through the strut assembly 7 and the rear support. The assembly 8 is deployed along the left and right directions, while the front bracket 1 and the rear bracket 2 are stretched along the front and rear direction under the action of the strut assembly 7 and the seat post 4, and the armrest bar 5 is supported between the push rod 3 and the front bracket 1.
当需要将该推车车架折叠起来时，首先将后附撑组件8沿图1中的A方向解锁，在将锁定机构解锁，使得滑动件6在后支架2上处于可滑动状态。向下压推杆3，使得滑动件6沿图1中的B方向向下滑动，带动推杆3的下部、座杆4的后部、撑杆71的后部随之向下运动，在后附撑组件8沿左右方向的收折作用下，以及撑杆71的后部逐渐下行的作用下，两撑杆71之间相对转动，两侧的侧支架100沿左右方向相互靠拢，前支架1与后支架2沿前后方向收拢。推杆3的下部与扶手杆5的后部逐渐下行而逐渐与后支架2靠拢，如图5所示，最终，前支架1、后支架2、推杆3、座杆4及扶手杆5均相互靠拢，撑杆组件7及后附撑组件8收拢在两侧的侧支架100之间，形成如图6所示结构。该折叠后的推车结构紧凑，各杆件紧密地收拢在一起，占用空间小，且可依靠前轮20与后轮30自立于地面，便于存放与携带。When the stroller frame needs to be folded, firstly, the rear support assembly 8 is unlocked along the direction A in FIG. Push down the push rod 3, so that the slider 6 slides downward along the B direction in Fig. Under the folding action of the supporting component 8 along the left and right direction, and under the action of the rear part of the strut 71 descending gradually, the two struts 71 rotate relative to each other, and the side brackets 100 on both sides move closer to each other along the left and right direction, and the front bracket 1 Fold together with the rear bracket 2 along the front and rear direction. The lower part of the push rod 3 and the rear part of the handrail rod 5 gradually descend and gradually move closer to the rear bracket 2, as shown in Figure 5, finally, the front bracket 1, the rear bracket 2, the push rod 3, the seat post 4 and the handrail rod 5 all Close to each other, the strut assembly 7 and the rear support assembly 8 are folded between the side brackets 100 on both sides, forming a structure as shown in FIG. 6 . The folded stroller has a compact structure, and the rods are tightly packed together, which takes up little space, and can stand on the ground by relying on the front wheels 20 and the rear wheels 30, which is convenient for storage and carrying.
当需要将该推车车架展开使用时，则仅需上拉推杆3，使得推杆3带动滑动件6沿后支架2上滑，撑杆71的后部及座杆3的后部逐渐上行，带动前支架1与后支架2沿前后方向逐渐展开，同时使得撑杆组件7与后附撑组件8沿左右方向展开而将两侧的侧支架100沿左右方向逐渐分离，直至推车车架完全展开后，滑动件6与后支架2通过锁定件锁定，推车车架便可稳定地处于展开状态下。When the stroller frame needs to be expanded and used, it is only necessary to pull up the push rod 3, so that the push rod 3 drives the slider 6 to slide up along the rear bracket 2, and the rear portion of the strut 71 and the rear portion of the seat post 3 gradually Upward, drive the front bracket 1 and the rear bracket 2 to gradually expand along the front and rear directions, and at the same time make the strut assembly 7 and the rear support assembly 8 expand along the left and right directions and gradually separate the side brackets 100 on both sides along the left and right directions until the cart After the frame is fully unfolded, the sliding part 6 and the rear bracket 2 are locked by the locking part, and the cart frame can be stably in the unfolded state.
综上，本发明的双向折叠推车，其结构简单，推车车架可沿前后方向和左右方向实现收折，折叠与展开操作均很简单，折叠后的推车车架上各杆件能够紧密地靠拢在一起，占用空间小，为用户的使用带来了方便。In summary, the two-way folding cart of the present invention has a simple structure, and the cart frame can be folded along the front-rear direction and the left-right direction, and the folding and unfolding operations are very simple, and each rod on the folded cart frame can They are close together and take up little space, which brings convenience to users.
