Embodiment 1

[0018] Embodiment one: if figure 1 , 2 As shown, the rear two-wheel drive dynamic baby carriage includes a carrier 1, a push handle 4, a chassis 6, a steering front wheel 3 and a rear wheel 2, and the steering front wheel 3 is arranged on the front portion of the chassis 6. The rear wheel stop hole 22 of the carrier 1 is inserted into the push handle 4 to prevent the carrier 1 from rotating.

[0019] A movable column 7 is fixed below the carrier body 1, and the movable column 7 is movably inserted into the guide sleeve 8. The lower end of the guide sleeve 8 is fixed to the middle part of the vehicle chassis 6. The guide sleeve 8 is covered with a spring 9, and the upper and lower ends of the spring 9 Respectively withstand the lower part of the carrier body 1 and the upper part of the undercarriage 6. When the carrier 1 moves upward, the kinetic energy consumption is large; when the carrier 1 moves downward, the phenomenon of gravity acceleration will be generated. This co...

Embodiment 2

[0026] Embodiment two: if image 3 Shown, the rear wheel structure of the present embodiment adopts ratchet type clutch. Several oblique teeth 30 are evenly distributed on the outer circumference of the clutch inner ring 20 . The inwall of rear wheel 2 is fixed clutch outer ring 25, and the inner circumference of clutch outer ring 25 forms two breaches 21 symmetrically, establishes a rotary ratchet 28 in the breach 21, and the other end of ratchet 28 links to each other with spring 29.

[0027] When the rear wheel 2 rotates forward, that is, clockwise, the spring 29 pushes out the ratchet 28, and the pawl 28 bears against the teeth 30 on the clutch inner ring 20. At this time, the clutch is in a combined state, and the rear wheel 2 and the clutch outer ring 25 drives the clutch inner ring 20 and the rear wheel shaft 5 to rotate synchronously by ratchet 28.

[0028] When the two rear wheels 2 rotate backward, that is, rotate counterclockwise, the pawl 28 and the clutch inner ...

Embodiment 3

[0030] Embodiment 3: In this embodiment, the ratchet is arranged on the inner ring of the clutch, and the teeth matching the ratchet are arranged on the inner circumference of the outer ring of the clutch. Other content of this embodiment is the same as that of Embodiment 2.

Abstract

The invention relates to a dynamic baby carrier driven by two rear wheels. A front wheel is arranged on the front of a chassis; a rear axle shaft is rotatably matched with the rear part of the chassis; a one-way clutch is respectively arranged between the rear wheels and the rear axle shaft; when the rear wheels rotate forwards, the one-way clutch drives the rear axle shaft to rotate synchronously; when the rear wheels rotate backwards, the rear wheels do not drive the rear axle shaft to rotate; a movable upright post is fixed under a supporting body and is movably inserted in a guide sleeve;the lower end of the guide sleeve is fixed with the middle part of the chassis; a spring is sleeved on the guide sleeve; the upper and lower ends of the spring support the lower part of the supportingbody and the upper part of the chassis respectively; and a driving shaft is arranged on the chassis below the movable upright post, and the rotation of the driving shaft makes the supporting body move up and down through a crank and a connecting rod. The baby carrier does not need external force and utilizes the thrust of the baby carrier to make the supporting body move in a certain rule, namelymove forwards in a wavy mode; and a baby seating in the baby carrier feels very comfortable, fresh and exciting, so that the baby carrier adapts to the active psychology of the baby and the baby seating for a long time cannot feel weary.

Description

technical field [0001] The invention belongs to the technical field of baby carriage manufacturing, in particular to a dynamic baby carriage driven by rear two wheels. Background technique [0002] Because the bearing body of the traditional stroller only moves in translation with the walking of the whole vehicle. Therefore, children sitting in it feel bored, and will get bored and resist it after a long time. In order to solve the above-mentioned problems existing in traditional baby carriages, the applicant once proposed to the State Intellectual Property Office a number of patent applications for dynamic baby carriages that can make the carrier body perform ups and downs. [0003] In order to solve the above-mentioned problems existing in the traditional baby carriage, the patent application of the present invention proposes a dynamic baby carriage with another technical solution different from the aforementioned patent application. Contents of the invention [000...
