Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the specific embodiments.

As shown in fig. 1-7, the carriage of the stroller of the present invention comprises a carriage body 1, a wheel assembly 2 disposed under the carriage body 1, and a connecting mechanism 3 for connecting the carriage body 1 and a frame of the stroller.

The connecting mechanism 3 comprises a connecting rod 3a and a sliding rod 3b, wherein the rear part of the connecting rod 3a is fixedly connected with the carriage body 1, the sliding rod is connected with the connecting rod 3a in a sliding manner, a first locking hook part 3c with an opening is arranged at the front end part of the connecting rod 3a, specifically, the opening direction of the first locking hook part 3c is arranged forwards, a second locking hook part 3d with an opening is arranged at the front end part of the sliding rod 3b, specifically, the opening direction of the second locking hook part 3d is arranged downwards or upwards, and therefore the connecting mechanism is beneficial to being clamped into a frame conveniently. The connecting mechanism 3 has a closed state and an open state, and as shown in fig. 1 to 3, when the connecting mechanism 3 is in the closed state, the opening of the second latch hook portion 3d is completely or partially closed by the first latch hook portion 3c, and a clamping space for clamping the vehicle frame is formed between the first latch hook portion 3c and the second latch hook portion 3 d. As shown in fig. 6 to 7, when the connecting mechanism 3 is in the open state, the second latch hook portion 3d is away from the first latch hook portion 3c so that the opening of the second latch hook portion 3d is completely exposed, and the connecting mechanism 3 further includes a locking device for locking the first latch hook portion 3c and the second latch hook portion 3d in the closed state.

Specifically, as shown in fig. 3-4 and 7, the link 3a is provided with a slide groove 4, the slide rod 3b is slidably disposed in the slide groove 4, and a first elastic member 7 is further disposed between the link 3a and the slide rod 3b so that the second latch hook portion 3d has a tendency to move away from the first latch hook portion 3 c.

As shown in fig. 3 to 4 and 7, the sliding rod 3b is provided with a first guide groove 5 extending in the sliding direction of the sliding rod 3b, the connecting rod 3a is provided with a guide pin 6, and the guide pin 6 is inserted into the first guide groove 5 and engaged therewith to regulate the sliding direction and the sliding distance of the sliding rod 3b, but the first guide groove 5 may be provided on the connecting rod 3a and the guide pin 6 may be provided on the sliding rod 3 b.

As shown in fig. 3 to 5 and 7, the locking device includes a second guide groove provided on the slide lever 3b to extend in the sliding direction of the slide lever 3b, and a lock pin 9 provided in the second guide groove to be slidable in the sliding direction of the slide lever 3 b. The second guide groove and the first guide groove 5 are provided in order in the direction in which the slide bar 3b slides. The second guide groove includes a sliding groove portion 8a and a locking groove portion 8b provided at the front end of the sliding groove portion 8a and having a height higher than that of the sliding groove portion, as shown in fig. 5, the lock pin 9 is provided with a first engaging portion 9a and a second engaging portion 9b, the first engaging portion 9a has a height greater than that of the sliding groove portion 8a and lower than that of the locking groove portion 8b, the second engaging portion 9b has a height lower than that of the sliding groove portion 8a, and the locking device further includes a second elastic member 10 provided between the link 3a and the slide 3b rod to cause the lock pin 9 to have a tendency to slide outward and cause the first engaging portion 9a to be engaged in the locking groove portion 8 b.

When the first engaging portion 9a is engaged with the locking groove portion 8b, the positions of the link 3a and the slide rod 3b are relatively fixed, the link mechanism 3 is in a closed state, and the locking device is in a locked state, and when the second engaging portion 9b is engaged with the second guide groove, the slide rod 3b can slide relative to the link 3a, and the locking device is in an unlocked state.

The usage principle of the child stroller planker is that in a locked state of the locking device, the first clamping portion 9a is clamped in the locking groove portion 8b, the lock pin is pressed along a direction perpendicular to the sliding direction of the sliding rod 3b relative to the connecting rod 3a, the second clamping portion 9b is clamped in the locking groove portion 8a, the sliding rod 3b slides outwards relative to the connecting rod 3a under the action of elastic force of the first elastic piece 7 due to the fact that the height of the second clamping portion 9b is lower than the height of the sliding groove portion 8a, the second clamping portion 9b slides in the sliding groove portion 8a, finally the second locking hook portion 3d is far away from the first locking hook portion 3c until an opening of the second locking hook portion 3d is completely exposed, the locking device is converted into an unlocked state, after a frame of the child stroller is clamped in the opening of the second locking hook portion 3d, the sliding rod 3b is pushed inwards, and the sliding rod 3b slides relative to the connecting rod 3a against the elastic force of the first elastic piece 7, at this time, the second engaging portion 9b of the lock pin 9 slides in the second guide groove, and when the second engaging portion 9b slides to the lock groove portion 8b, the lock pin 9 slides outward in a direction perpendicular to the sliding direction of the slide lever 3b with respect to the link lever 3a due to the elastic force of the second elastic member 10, and finally the first engaging portion 9a is engaged in the lock groove portion 8b, and the lock device is switched to the locked state.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
