[0016] Hereinafter, the technical means in the present embodiment will be described clearly and completely with reference to the drawings in the present embodiment, but obviously, the described embodiment is only a part of the present embodiment, not all of the embodiments. Based on the present embodiment, all other embodiments that a person skilled in the art can obtain without creative labor are all included in the scope of protection of the present embodiment.

[0017] The present invention aims to provide an integrated artificial shuttlecock to solve the problems existing in the prior art.

[0018] In order to make the above objectives, features and advantages of the present invention clearer and easier to understand, the present invention will be described in more detail below in combination with drawings and specific embodiments.

[0019] As shown in Figures 1 to 4, the one-piece artificial shuttlecock of this embodiment includes a cork 1, a skirt portion 2, and a feather 3, a groove 11 is formed downward on the top end surface of the cork 1, and an annular insertion groove 12 is formed downward on the bottom of the groove 11, the skirt portion 2 includes a cylinder 21 inserted into the insertion groove 12 and a support disk 22 installed on the top of the cylinder 21 and inserted into the groove 11, a plurality of feathers 3 are installed on the outer periphery of the support disk 22, the feather 3 includes an integrally molded feather piece 31 and feather handle 32, the feather piece 31 is installed on the top of the feather handle 32, and the bottom of the feather handle 32 is connected to the support disk 22, and the cylinder 21, the support disk 22 and the feather 3 are of an integrally molded structure.

[0020] In order to firmly fix the skirt portion 2 after it is inserted into the cork 1, an annular engagement portion 24 is provided around the bottom of the cylinder 21, and the annular engagement portion 24 is pressed into the insertion groove 12 from the top opening of the insertion groove 12, and finally forcibly pressed into the bottom side wall of the insertion groove 12, thereby realizing the axial position restriction of the skirt portion 2.

[0021] Two further position limiting portions 23 are protruding outward from the cylindrical wall of the cylinder 21, and the two position limiting portions 23 are installed symmetrically, with the width of the position limiting portions 23 gradually narrowing from the top to the bottom. When the cylinder 21 is inserted into the insertion groove 12, the position limiting portions 23 are subjected to force and forcibly pushed into the side wall of the insertion groove 12, thereby combining with the skirt portion 2 and the cork 1 to prevent loosening in the axial and radial directions.

[0022] In this specific embodiment, the groove 11 is a tapered groove whose diameter gradually decreases from the top end to the bottom end, and the support disk 22 is a tapered plate that fits into the groove 11.

[0023] In this specific embodiment, the feathers 3 are 16 in total, and are feathers 3 following the shape of natural goose or duck feathers, and the outer dimensions of the feather handle 32 are similar to the feather handle of natural goose or duck feathers, and its structural shape is an asymptotic U-shape, so as to achieve the optimal hitting effect by the strength, toughness and elasticity of the feather handle 32. A molding die is used to make the feather pieces 31 follow the shape of the feathers 3, and a heating element is attached to the die to generate high temperature, and when the temperature reaches the melting point of the plastic, the feather pieces are made to follow the shape of natural feathers through a melting press molding process.

[0024] In this particular embodiment, the skirt 2 and the wings 3 are of a plastic material.

[0025] The manufacturing method of the one-piece artificial muscle shuttlecock in this embodiment is as follows.

[0026] The skirt portion 2 and the feathers 3 are molded integrally by precision injection molding, and each feather 3 after molding is in a state of being expanded horizontally (as shown in FIG. 5), a connection point is provided between the base of the feather stalk 32 and the support disk 22 of the skirt portion 2, a locking block 33 is installed vertically at the upper end of the base of the feather stalk 32, and locking grooves 34 (as shown in FIG. 6) corresponding one-to-one to each locking block 33 are distributed in the circumferential direction of the top of the support disk 22, the connection points between the feather stalk 32 and the support disk 22 are heated to make each feather 3 stand, and each locking block 33 is fitted into the corresponding locking groove 34, and further the feather stalk 32 and the support disk 22 are welded together. After that, the skirt portion 2 with the feathers 3 attached is inserted into the insertion grooves 12 and 11 of the cork 1 to complete the assembly of the shuttlecock.

[0027] Specifically, the blade stalk 32 and the support disc 22 are welded together by an ultrasonic welding process.

[0028] A semicircular position limiting portion 35 is protruded from one end side of the locking block 33 away from the impeller 32 so that the locking block 33 is radially position-limited after being locked in the locking groove 34, and the position limiting portion 35 is position-limited within a semicircular position limiting groove 36 installed on one side of the locking groove 34, thereby realizing radial position limiting of the locking block 33.
