[0032] Embodiment One

[0033] Referring to Figures 1 to 5 As shown, the present embodiment provides a sound-damping and shock-absorbing badminton racket, which includes a first panel 11, a second panel 12, and a honeycomb panel 13 arranged between the first panel 11 and the second panel 12. Specifically, the first panel 11, the honeycomb panel 13, and the second panel 12 form a racket face 101 and a handle 102, so that the racket face 101 and the handle 102 are integrally connected. Of course, in other embodiments, the first panel 11, the honeycomb panel 13, and the second panel 12 can only form the racket face 101 part, and the handle 102 part can be implemented by other structures.

[0034] ​Specifically, at the position of the racket face 101 of the badminton racket, the outer edges of the first panel 11 and the second panel 12 protrude from the honeycomb panel 13 to form a peripheral accommodating groove 100. Specifically, in the present embodiment, at the position of the racket face 101 of the badminton racket, the outer edges of the first panel 11 and the second panel 12 both protrude from the honeycomb panel 13, that is, the entire periphery at the position of the racket face 101 forms the peripheral accommodating groove 100. The peripheral accommodating groove 100 is filled with a buffer elastic body 21 foamed from foaming material, and the buffer elastic body 21 is provided with a spring sheet 22. That is, the buffer elastic body 21 with the spring sheet 22 surrounds the entire periphery of the racket face 101. Specifically, the buffer elastic body 21 can be made of materials that can be foamed, such as EVA (ethylene-vinyl acetate copolymer) and epoxy resin in the prior art.

[0035] The present application adopts the above structure, the inner core of the racket face 101 is the honeycomb panel 13 for hitting, and the periphery is the buffer elastic body 21 with the spring sheet 22, so that effective sound damping and shock absorption effects can be achieved; the structure design is simple; at the same time, the foamed buffer elastic body 21 is light in weight and basically does not increase the overall weight of the racket, thereby ensuring the hitting feeling.

[0036] Further preferably, the spring sheet 22 is made of carbon fiber material, further ensuring lightweight. In the present embodiment, the spring sheet 22 is a long strip-shaped spring sheet with a U-shaped cross section, the length direction of the spring sheet 22 is consistent with that of the buffer elastic body 21, so that the cross section of the periphery of the racket face 101 is basically consistent, the weight distribution is relatively uniform, and the force is also relatively uniform. At the same time, the opening of the U-shaped spring sheet is arranged to face the honeycomb panel 13, which can better absorb the vibration. Of course, in other embodiments, the material of the spring sheet 22 can also be metal or plastic, etc. with certain elasticity, the shape of the spring sheet 22 can also be a long strip-shaped structure with a V-shaped or W-shaped cross section, and the arrangement direction of the spring sheet 22 can also be changed, such as the opening of the U-shaped spring sheet facing outward, etc. The spring sheet 22 can also be a small piece of spring sheet with a short length, so that multiple spring sheets 22 can be distributed at equal intervals along the length direction of the buffer elastic body 21, but the effect achieved can be poorer.

[0037] In the width direction of the racket face 101, the depth of the peripheral accommodating groove 100 accounts for 10%-25% of the radius of the first panel 11 or the second panel 12. In this way, under the condition that the area size of the racket face 101 remains unchanged, the sufficient occupying area of the honeycomb panel 13 (that is, sufficient hitting position) is ensured, and the sufficient installation of the buffer elastic body 21 is also ensured, thereby achieving significant sound damping and shock absorption effects; and in the case that the length direction size of the racket face 101 is large enough, the depth of the peripheral accommodating groove 100 in the width direction can also be appropriately deepened.

[0038] Further, in the embodiment, the outer edge of the buffer elastic body 21 is connected with a wear-resistant layer 23, which can be made of rubber or other wear-resistant materials. Specifically, the wear-resistant layer 23 and the buffer elastic body 21 are fixed by gluing; the connection is firm and not easy to fall off. At the same time, the wear-resistant layer 23 is also fixedly attached to the outer edge of the first panel 11 and the second panel 12, which also protects the outer edge of the first panel 11 and the second panel 12, and avoids the buffer elastic body 21 from being exposed. Of course, in other embodiments, the wear-resistant layer 23 can also be fixed by using existing hard frames, or if the buffer elastic body 21 itself has wear-resistant properties, the structure of the wear-resistant layer 23 can also not be used.

[0039] Further, in the embodiment, the buffer elastic body 21 also protrudes from the outer edge of the first panel 11 and the second panel 12, forming a central arch structure; appropriately increasing the amount of buffer elastic body 21, the sound reduction and shock absorption effect will be better.

[0040] The above discloses a more preferred embodiment of the present application, of course, in other embodiments, the peripheral accommodating groove 100 can also be formed on the left and right sides of the face 101 (i.e. the two sides in the width direction), or on the half circle away from the handle 102, etc.

[0041] Specifically, the embodiment also provides a preparation method of the above-mentioned sound reduction and shock absorption pick-up racket, which comprises the following steps:

[0042] S1, providing a foaming mold, adding a spring sheet 22 in the mold, then filling the foaming material in the mold, and obtaining a long strip-shaped buffer elastic body 21 after the foaming material is fully foamed; Specifically, the mold has the same cavity structure as the peripheral accommodating groove 100, so that it can be adapted to the peripheral accommodating groove 100 after molding.

[0043] Since the wear-resistant layer 23 is added, the embodiment also includes step S1-1, gluing a layer of wear-resistant layer 23 on the outside of the buffer elastic body 21.

[0044] S2, providing a punch and a die, the die has a racket shape accommodating groove, the first panel 11 is first placed in the accommodating groove, then the buffer elastic body 21 with the spring sheet 22 is placed along the side of the accommodating groove, specifically, in the embodiment, the outer side of the buffer elastic body 21 is provided with the wear-resistant layer 23, therefore, the wear-resistant layer 23 is attached to the side of the accommodating groove, when there is no wear-resistant layer 23 structure, the outer side of the buffer elastic body 21 is directly attached to the side of the accommodating groove; then the honeycomb panel 13 is placed in the middle of the buffer elastic body 21, so that the buffer elastic body 21 and the honeycomb panel 13 are in the same layer; finally, the second panel 12 is placed on the surface of the honeycomb panel 13 and the buffer elastic body 21;

[0045] S3, the punch is pressed to the concave die, finally the first panel 11, the buffer elastic body 21, the honeycomb panel 13 and the second panel 12 placed in the accommodating groove are formed by stamping, and the sound-damping and shock-absorbing pick racket is obtained.

[0046] The preparation scheme has the advantages of simple preparation, easy implementation and low cost.

[0047] Embodiment two

[0048] The sound-damping and shock-absorbing pick racket provided in the embodiment is substantially the same as the sound-damping and shock-absorbing pick racket provided in embodiment one, except that the buffer elastic body 21 does not have the elastic sheet 22 in the embodiment, that is, the buffer elastic body 21 filled in the peripheral accommodating groove 100 is entirely the buffer elastic body 21 obtained by foaming the foaming material. Compared with embodiment one, the sound-damping effect is equivalent, but the shock-absorbing effect is poorer, but the sound-damping and shock-absorbing effects are still remarkable, and the cost is lower. The selection can be made according to actual needs.

[0049] The preparation method of the sound-damping and shock-absorbing pick racket provided in the embodiment does not put the elastic sheet in the mold in step S1, but directly foams the buffer elastic body 21.

[0050] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all the changes are within the protection scope of the utility model.
