1. A wheel assembly for an infant carrier apparatus, comprising: a shock absorber formed integrally in a single body comprising a cushion structure capable of elastic deformation, and a mount structure connected with the cushion structure and having a tubular shape adapted to assemble with a support frame of an infant carrier apparatus, wherein the mount structure includes a first, a second and a third portion that are formed integrally with the shock absorber, the first portion having a tubular shape, the second portion having a hole and extending from the tubular shape, and the third portion extending upwardly from the second portion, and the cushion structure includes an arm connected with the tubular shape and the third portion;a wheel shaft assembled through the hole of the second portion;at least a wheel pivotally coupled with the wheel shaft; anda brake element assembled with the third portion and operable to block rotation of the wheel. 2. The wheel assembly according to claim 1, wherein the cushion structure extends between the tubular shape and the third portion of the mount structure. 3. The wheel assembly according to claim 1, wherein the arm extends along a direction along which are arranged a plurality of cavities. 4. The wheel assembly according to claim 1, wherein a second arm is connected between the second portion and the first portion of the mount structure, the second arm being located below the arm and being formed integrally with the shock absorber. 5. The wheel assembly according to claim 4, wherein a gap is defined between the arm connected with the tubular shape and the third portion, and the second arm connected with the second portion and the first portion. 6. The wheel assembly according to claim 5, wherein the gap is delimited forwardly by the tubular shape, and rearwardly by the third portion. 7. The wheel assembly according to claim 4, wherein the arm connected with the tubular shape and the third portion is configured to deform differently from the second arm connected with the second portion and the first portion. 8. The wheel assembly according to claim 1, wherein the third portion includes a slot through which is pivotally connected the brake element, the slot having two opposite sidewalls provided with first and second locking grooves, and the brake element having a stud that engages with the first locking groove to keep the brake element in a braking position, and with the second locking groove to keep the brake element in a release position. 9. The wheel assembly according to claim 1, wherein the shock absorber is made of a thermoplastic polyester elastomer. 10. An infant stroller comprising: a support frame; andthe wheel assembly according to claim 1 mounted with the support frame. 11. A wheel assembly for an infant carrier apparatus, comprising: a shock absorber formed integrally in a single body comprising a first portion having a tubular shape adapted to affix with a support frame, a second portion extending from the first portion, a third portion extending upwardly from the second portion, and a cushion structure capable of elastic deformation and extending between the first and third portions, the cushion structure including an arm oppositely connected with the first portion and the third portion;at least a wheel pivotally assembled with the second portion via a wheel shaft that passes through the wheel and the second portion of the shock absorber; anda brake element assembled with the third portion and operable to block rotation of the wheel. 12. The wheel assembly according to claim 11, wherein the arm extends along a direction along which are arranged a plurality of cavities. 13. The wheel assembly according to claim 11, wherein a second arm is connected between the second portion and the first portion, the second arm being located below the arm. 14. The wheel assembly according to claim 13, wherein a gap is defined between the arm connected with the tubular shape and the third portion, and the second arm connected with the second portion and the first portion. 15. The wheel assembly according to claim 13, wherein the arm connected with the first portion and the third portion is configured to deform differently from the second arm connected with the second portion and the first portion. 16. The wheel assembly according to claim 11, wherein the third portion includes a slot through which is pivotally connected the brake element, the slot having two opposite sidewalls provided with first and second locking grooves, and the brake element having a stud that engages with the first locking groove to keep the brake element in a braking position, and with the second locking groove to keep the brake element in a release position. 17. The wheel assembly according to claim 11, wherein the shock absorber is made of a thermoplastic polyester elastomer. 18.
