Abstract
A wheel shock absorption structure and a child carrier having the wheel shock absorption structure, including a wheel shaft and a wheel seat connected with a frame, and a lower end of the wheel seat is rotatably connected with a wheel through the wheel shaft. Further including a shock absorber with an elastic structure, an upper end of the shock absorber is removably connected with an upper end of the wheel seat, and the shock absorber rotates synchronously along with the wheel seat; a lower end of the shock absorber is rotatably connected with the wheel shaft which is slidably connected with the lower end of the wheel seat. The shock absorber is driven by sliding of the wheel shaft to generate recoverable elastic deformation to provide damping and buffering. The bending deformation of the shock absorber ensures that the wheel shock absorption structure has a better shock absorbing effect.
