Description

Technical Field

[0001] The utility model relates to the technology of the racket field, and in particular to a racket structure with a built-in 3D printed part. Background Art

[0002] Rackets (such as badminton and tennis rackets) are high-powered sports equipment characterized by minimal material usage, high net tension on the frame, and significant deformation of the shaft during impact. World-renowned brands, in the development of high-performance badminton and tennis rackets, are eager to achieve breakthroughs in production technology and structural design to achieve market leadership.

[0003] Take a badminton racket as an example. A badminton racket generally consists of a frame, a handle, and a tube connecting the frame and handle. A badminton racket is typically no longer than 68 cm, with the handle and tube extending no further than 42 cm. The frame is no longer than 25 cm and is 20 cm wide. With the advancement of science and technology, rackets are developing towards lighter weight, stiffer frames, more flexible tubes, and lower air resistance.

[0004] In the prior art, racket components such as the frame, center tube, and handle are generally composed of an inner layer made of foam material and an outer layer made of fiber material. This structure results in a weak core structure, making it prone to breakage and hindering the ability to increase hitting power. Therefore, improvements are needed to address this issue. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a racket structure with built-in 3D printed parts, which can effectively solve the problem of relatively weak central structural strength of existing rackets.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A racket structure with a built-in 3D printed part includes a racket frame, a middle tube, and a handle; the front end of the middle tube is fixedly connected to the rear end of the racket frame, and the front end of the handle is fixedly connected to the rear end of the middle tube; at least a portion of the racket frame, middle tube, or handle is built-in with a 3D printed part.

[0008] As a preferred solution, the racket frame, middle tube and handle all include an inner layer and an outer layer. The inner layer is made of foam material, and the 3D printed part is inlaid and fixed in the inner layer. The outer layer is made of fiber material and is coated on the outside of the inner layer. The structure is simple and easy to manufacture.

[0009] As a preferred solution, the 3D printed part is a metal, plastic or resin 3D printed part.

[0010] As a preferred solution, the 3D printed part is a multi-dimensional angular structural part, which has multiple support rods inside to form a multi-angle support structure, and internal gaps are formed between the support rods, and the inner layer is filled into the internal gaps.

[0011] As a preferred solution, the center of the 3D printed part has a hollow cavity, and the inner layer is simultaneously filled into the hollow cavity.

[0012] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] By embedding 3D printed parts in at least part of the racket frame, middle tube or handle, the 3D printed parts are equivalent to the steel frame structure in reinforced concrete, which can effectively enhance the structural strength of the center of the racket. The structure of the racket can be reinforced at local positions as needed to prevent the racket from breaking easily. At the same time, according to the different directions of the resistance required by the racket, the corresponding support angle structure can be pre-designed on the 3D printed parts, which is conducive to enhancing the hitting force and improving the performance of the product.

[0014] In order to more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figures 1 to 2 As shown, it shows the specific structure of the first preferred embodiment of the present invention, including a racket frame 10, a middle tube 20 and a handle 30.

[0025] The front end of the middle tube 20 is fixedly connected to the rear end of the racket frame 10 , and the front end of the handle 30 is fixedly connected to the rear end of the middle tube 20 . Moreover, at least a portion of the racket frame 10 , the middle tube 20 or the handle 30 is embedded with a 3D printed part 40 .

[0026] In this embodiment, the racket frame 10, middle tube 20, and handle 30 all include an inner layer 101 and an outer layer 102. The inner layer 101 is made of foam, and the 3D-printed component 40 is inlay-molded and fixed within the inner layer 101. The outer layer 102 is made of fiber and is coated on the outer layer 101, resulting in a simple structure and easy production. Furthermore, the 3D-printed component 40 is a 3D-printed component made of metal, plastic, or resin. The metal can be various materials, such as titanium, providing excellent structural strength. Furthermore, the 3D-printed component 40 is a multi-dimensional angular structural component, internally comprising multiple support rods 41 to form a multi-angle support structure. Internal gaps 42 are formed between each support rod 41, and the inner layer 101 fills these internal gaps 42, further increasing structural strength. The direction and number of support rods 111 can be designed to support forces in different directions as needed for the racket.

[0027] The production process of this embodiment is described in detail as follows:

[0028] First, a 3D printed part 40 is formed by 3D printing. Then, an unfoamed material is filled into the 3D printed part 40. Then, an uncured fiber cloth is wrapped around the unfoamed material to form a semi-finished product. Then, the semi-finished product is placed in a mold and heated. The unfoamed material is heated and expands to squeeze the fiber cloth, and the fiber cloth is heated and cured to be shaped, thereby making a racket.

[0029] Please refer to Figure 3 As shown, it shows the specific structure of the second preferred embodiment of the utility model. The specific structure of this embodiment is basically the same as the specific structure of the first preferred embodiment mentioned above, except that:

[0030] In this embodiment, the center of the 3D printed part 40 has a hollow cavity 43 , and the inner layer 101 is simultaneously filled into the hollow cavity 43 .

[0031] The design focus of the present utility model is that by embedding a 3D printed part in at least a portion of the racket frame, the middle tube or the handle, the 3D printed part is equivalent to the steel frame structure in reinforced concrete, which can effectively enhance the structural strength of the center of the racket. The structure of the racket can be reinforced at a local position as needed to prevent the racket from being easily broken. At the same time, according to the different directions of the resistance required by the racket, the corresponding support angle structure can be pre-designed on the 3D printed part, which is conducive to enhancing the hitting force and improving the performance of the product.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
