As shown in Figures 2 to 5, the folding frame 4 includes an intermediate rod 41 hinged with the seat frame 2, the middle part of the intermediate rod 41 is hinged with a rear link 42, and the rear link 42 on the The other end is hinged on the rear side of the underframe 1 , and the first locking device 5 is arranged between the lower end of the middle rod 41 and the middle part of the underframe 1 .

As shown in Figure 5 and Figure 14, the first locking device 5 includes a locking block 51 arranged in the middle of the chassis 1, the locking block 51 is provided with a locking groove 52, and the middle rod 41 is provided with a locking pin 53 that can slide therein and cooperate with the locking groove 52 , and the middle rod 41 is also provided with a return spring 54 that can reset the locking pin 53 .

As shown in Figure 14, the locking block 51 is provided with an inclined oblique block 55, and the middle rod 41 is provided with an oblique groove 56 matching with the oblique block 55, and the locking block A positioning groove 57 is also provided on the 51, and a positioning block 58 that can cooperate with the positioning groove 57 when the oblique block 55 cooperates with the oblique groove 56 is provided on the middle rod 41 .

As shown in FIG. 13 , a third linkage rod 65 hinged to the second linkage rod 64 and the seat frame 2 may also be arranged between the second linkage rod 64 and the seat frame 2 . Due to the addition of the third linkage rod 65, the swing range of the seat frame 2 can be increased.

As shown in FIGS. 1 to 3 , a push handle 9 can also be hinged on the seat frame 2 .

working principle:

As shown in Fig. 3, Fig. 10 and Fig. 14, because the middle bar 41 is hinged with the seat frame 2, the rear link 42 is hinged at the middle part of the middle bar 41, and the other end of the rear link 42 is hinged at the rear side of the chassis 1, and, The second linkage rod 64 is hinged with the seat frame 2, therefore, when the locking pin 53 withdraws from the locking groove 52, the first locking device 5 is unlocked, and a forward thrust is applied to the lower end of the middle rod 41 at this moment, and the oblique Disengage from block 55 with oblique groove 56, now just can fold rocking car, and the effect of locating groove 57 and positioning block 58 is to start the effect of positioning when rocking car is launched.

As shown in Fig. 1, Fig. 8, Fig. 10, Fig. 11, Fig. 12, Fig. 15 and Fig. 16, when the swing car is in the unfolded state, the first locking device 5 is locked. By applying a rotational force to the interlocking block 81, the interlocking block 81 is rotated, and since the hinge axis of the locking shaft 82 and the interlocking block 81 is in an eccentric state, the locking shaft 82 is snapped in during the rotation of the interlocking block 81. into the draw-in groove 31 of the traveling wheel 3, and, during the rotation of the interlocking block 81, the drag cable 83 which is passed through the underframe 1 and connected with the rotating disk 71 is pulled, and the drag cable 83 drives the rotating disk 71 Rotate, the rotating disc 71 is in the process of rotating, the locking block 72 that was originally resisted by the pushing slope 75 on the rotating disc 71 slides into the arc-shaped receiving groove 74 under the action of the return spring 73, and the locking on the locking block 72 now The groove 77 is disengaged from the second linkage rod 64, and the locking block 72 will no longer limit the swing of the second linkage rod 64. Therefore, when the drive motor 62 rotates, the first linkage rod 63 drives the second linkage rod 64 to swing , the second linkage rod 64 drives the front end of the seat frame 2 to swing, and because the seat frame 2 is hinged with the middle rod 41, the entire seat frame 2 can swing. In the whole movement, the second linkage rod 64 will drive The fourth linkage rod 67 rotates, and the fourth linkage rod 67 plays a role of stability and balance.

As shown in Fig. 1, Fig. 5 to Fig. 7, Fig. 11, Fig. 12, Fig. 15 and Fig. 16, when the swing car is required to walk, the first locking device 5 is locked at this moment. By applying a rotational force to the interlocking block 81, the interlocking block 81 is rotated, and then the locking shaft 82 is withdrawn from the draw-in groove 31 of the road wheel 3 during the rotation of the interlocking block 81, and the interlocking block 81 During the rotation process, the drag cable 83 that is installed in the underframe 1 and connected with the rotating disk 71 is pulled, and the drag cable 83 drives the rotating disk 71 to rotate. The inclined plane 75 just pushes the locking block 72 to move axially. At this time, the return spring 73 is compressed. After the locking block 72 moves axially, the locking groove 77 on the locking block 72 is locked with the second linkage rod 64. Linkage bar 64 just can not swing, and therefore, this moment, seat frame 2 just can not be driven and swing by drive motor 62, and this moment, swing car is used as baby carriage. The potential safety hazard caused by the swing of the seat frame 2 when walking as a stroller is avoided.

The swing car of the utility model ensures the safety and reliability of the use of the swing car through a plurality of joint control mechanisms.
