Abstract

A shock absorbing structure of a racket contains: a head and an absorption member matingly contacting with an internal fence of the head. The absorption member is a hollowly tubular structure and covers the internal fence totally. When the head is made of carbon-fiber composite material, the absorption member is made of any one of Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU). When the head is made of metal or aluminum alloy, the absorption member is made of any one of Thermosetting Elastomers, Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU). When the head and the absorption member are made of different materials, an amplitude of the head is different from an amplitude of the absorption member, and the head interferes the absorption member, thus absorbing vibration.

Claims (11)

1 . A shock absorbing structure of a racket comprising:

a head and an absorption member matingly contacting with an internal fence of the head;

wherein the absorption member is multiple parallel straps;

wherein the multiple parallel straps of the absorption member are separately arranged on the internal fence of the head, and a gap is defined between any two adjacent parallel straps

wherein an area of a part of the internal fence covered by the absorption member is more than an area of the other of the internal fence which is not covered by the absorption member.

2 . The shock absorbing structure as claimed in claim 1 , wherein the absorption member is a hollowly tubular structure and covers the internal fence totally.

3 . The shock absorbing structure as claimed in claim 1 , wherein a corner of the internal fence of the head is covered by the absorption member.

4 . The shock absorbing structure as claimed in claim 1 , wherein when the head is made of carbon-fiber composite material, the absorption member is made of any one of Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU).

5 . The shock absorbing structure as claimed in claim 1 , wherein when the head is made of metal or aluminum alloy, the absorption member is made of any one of Thermosetting Elastomers, Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU).

6 . The shock absorbing structure as claimed in claim 1 , wherein the racket is any one of a tennis racket, a badminton racket and a squash racket.

7 . The shock absorbing structure as claimed in claim 6 , wherein the tennis racket includes a handle, a connection tube, and a frame which are tubular and are configured to define and surround the head.
