Embodiment 1

[0018] refer to figure 1 , figure 2 and image 3 , the baby carriage rear wheel shock-absorbing linkage device, the baby carriage includes a vehicle frame 1 and the rear wheel axle 2, the baby carriage rear wheel shock-absorption linkage device includes a round bar 4 and two linkage torsion springs 3, the round bar 4 is arranged on the vehicle frame 1 and is connected with The rear wheel axles 2 are parallel, and each linkage torsion spring 3 is connected between the vehicle frame 1 and the rear wheel axle 2; each linkage torsion spring 3 is composed of a torsion spring body 31 and a support rod 32, and the torsion spring body 31 is socketed On the round bar 4, the two ends of the torsion spring body 31 are fixed end 01 and free end 02 respectively.

[0019] The rear wheel shock-absorbing linkage device of the stroller also includes a driving motor 9, two rotating discs 5 and two rocking arms 8; Cam 6 is fixedly connected on each rotating disc 5, and each rotating disc 5 i...

Embodiment 2

[0022] refer to Figure 4 , the difference from the first embodiment is that the round rod 4 is fixed on the frame 1, and the fixed end 01 of the torsion spring body 31 is fixed on the frame 1. This embodiment simplifies the structure and reduces the cost.

[0023] In the present invention, the round bar is arranged on the vehicle frame and is parallel to the rear wheel axle, and two interlocking torsion springs are connected between the vehicle frame and the rear wheel axle. Function, when anti-vibration, it can not only anti-vibration in the up and down direction, but also anti-vibration in the front and rear direction.

Abstract

The invention provides a baby carrier rear wheel damping linkage device which aims at solving the problem that in the prior art, the damping effect of a damping device is poor. A baby carrier comprises a frame and a rear wheel axle. The baby carrier rear wheel damping linkage device comprises a round rod and two linkage torsion springs. The round rod is arranged on the frame and is parallel to the rear wheel axle, and both the linkage torsion springs are connected between the frame and the rear wheel axle. Each linkage torsion spring is formed by a torsion spring body and a supporting rod, wherein the torsion spring body is connected to the round rod in a sleeving mode, the two ends of the torsion spring body are a fixed end and a free end respectively, one end of the supporting rod is fixedly connected with the free end of the torsion spring body, and the other end of the supporting rod is connected to the rear wheel axle. According to the baby carrier rear wheel damping linkage device, the round rod is arranged on the frame and is parallel to the rear wheel axle, the two linkage torsion springs are connected between the frame and the rear wheel axle and can play both the role in transmitting power and the role in damping, and both damping in the vertical direction and damping in the front and rear direction are achieved in the damping process.

Description

technical field [0001] The invention relates to a shock-absorbing device for a baby carriage, in particular to a device capable of both shock-absorbing and linkage functions. Background technique [0002] The shock absorption on the current baby carriage is generally set under the seat to play the role of up and down shock absorption, because when the baby carriage backs up, when it hits something, it will cause greater damage to the child, and it will cause a lot of damage to the child when walking backwards on uneven roads. , comfort is also relatively poor; existing shock absorbers generally only play the effect of shock absorption, but do not play the role of linkage, and the shock absorption effect is not obvious. Contents of the invention [0003] The invention provides a rear wheel shock-absorbing linkage device of a stroller, aiming at solving the problem of poor shock-absorbing effect of the shock-absorbing device in the prior art. [0004] In order to solve the ...
