[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] See also Figures 1 to 3 The utility model provides a vibration-damping handle structure for striking sports equipment, comprising an inner handle body 1, an outer handle body 2 and a plurality of vibration-damping bodies 3, wherein the outer handle body 2 wraps the inner handle body 1, and each of the vibration-damping bodies 3 comprises a first vibration-damping plate 31 embedded in the inner side of the outer handle body 2 and a second vibration-damping plate 32 embedded in the outer side of the outer handle body, as well as a plurality of vibration-damping connecting columns 33 fixedly connected between the first vibration-damping plate 31 and the second vibration-damping plate 32.

[0031] In this embodiment, the vibration-damping connecting column 33 is integrally formed with the first vibration-damping plate 31 and the second vibration-damping plate 32, and can also be detachably connected. The vibration-damping connecting column 33 can be cylindrical or polygonal. The inner handle body 1, the outer handle body 2 and the vibration-damping body 3 can be bonded by adhesive, or a snap-fit ​​structure can be added to the surfaces of the three for snap-fit ​​connection.

[0032] Alternatively, if Figure 3 As shown, the first vibration damping plate 31 is partially embedded in the inner side of the outer handle body 2, and the second vibration damping plate 32 is partially embedded in the outer side of the outer handle body 2; Figure 4 As shown, the first vibration damping plate 31 is completely embedded in the inner side of the outer handle body 2, and the second vibration damping plate 32 is partially embedded in the outer side of the outer handle body 2; Figure 5 As shown, the first vibration damping plate 31 is partially embedded in the inner side of the outer handle body 2, and the second vibration damping plate 32 is fully embedded in the outer side of the outer handle body 2; Figure 6 As shown, the first vibration damping plate 31 is fully embedded in the inner side of the outer handle body 2 , and the second vibration damping plate 32 is fully embedded in the outer side of the outer handle body 2 .

[0033] When the racket generates vibration force when hitting the ball, the vibration force is transmitted from the racket plate to the racket shaft (grip structure), first to the inner handle body 1, and the inner handle body 1 is then transmitted outward to the outer handle body 2, and the vibration damping body 3 runs through the inner and outer sides of the outer handle body 3 to absorb the vibration force transmitted from the inner handle body 1 to the outer handle body 2, thereby achieving a vibration damping effect; and a first vibration damping plate 31, a vibration damping connecting column 33 and a second vibration damping plate 32 are used to triple absorb the vibration force generated by the racket hitting the ball, and a plurality of vibration damping connecting columns are used to fix the first vibration damping plate 31 and the second vibration damping plate 32 to strengthen the connection between the first vibration damping plate 31 and the second vibration damping plate 32, so that the two vibration damping plates offset each other's vibration force, thereby improving the vibration damping effect and thus enhancing the user's grip and hitting feel.

[0034] In some embodiments, Figure 7As shown, the vibration-damping connecting columns 33 are filled with foamed resin material 34, and the first vibration-damping plate 31, the second vibration-damping plate 32 and the vibration-damping connecting column 33 can be made of foamed resin material with vibration-damping effect. Foamed resin materials include but are not limited to polyurethane PU, polystyrene EPS, polypropylene PP, ethylene-vinyl acetate copolymer EVA and vibration-absorbing polymer materials (VPM). Foamed resin materials can form a porous structure, which can improve the vibration-damping effect by using the porous structure while supporting the first vibration-damping plate 31 and the second vibration-damping plate 32.

[0035] Optionally, the diameter of the vibration-damping connecting column 33 is 3 mm to 5 mm, and the interval between a plurality of the vibration-damping connecting columns 33 is 8 mm to 20 mm.

[0036] Optionally, the vibration-damping body 3 and / or the vibration-damping connecting column 33 have a density of 0.1 g / cm 3 ~0.3g / cm 3 Vibration absorbing materials, such as ETPU. Vibration absorbing materials include one of polyurethane, polystyrene, polypropylene, ethylene-vinyl acetate copolymer and vibration absorbing polymer materials (VPM). The density range of vibration absorbing materials is 0.1g / cm 3 ~0.3g / cm 3 , thickness 1-3mm, compared to ordinary materials that absorb energy through macroscopic structural single-layer compression deformation, the VPM material used in this embodiment absorbs energy through molecular structure and micro-nano pore multi-level structure compression, achieving exponential growth in structure, thereby bringing more time delay and energy dissipation in the process of multi-level structural deformation. During the impact process, it can absorb more than 50% of the impact force and instantly convert the impact energy into slight heat energy for dissipation.

[0037] Alternatively, if Figure 2 As shown, the number of the vibration dampers 3 is two, and they are symmetrically embedded on both sides of the outer handle body 2 to offset the opposite vibration forces.

[0038] In some embodiments, the inner handle body 1 is an I-shaped, X-shaped or cross-shaped structure with a hollow structure. Figure 2 The I-shape shown has an I-shape armpit with a hollow structure to improve the vibration absorption capability of the inner handle body 1.

[0039] Alternatively, if Figure 2 As shown, the hollow structure is adjacent to the first vibration damping plate 31 to quickly absorb the vibration force not absorbed by the hollow structure and improve the vibration damping effect.

[0040] In some embodiments, Figure 8As shown, for a badminton racket or other racket, an extension portion 11 is extended outward from one end of the inner handle body 1, and the diameter of the extension portion 11 gradually decreases from one end close to the inner handle body 1 to the other end, and the extension portion 11 can be conical or trapezoidal. Adding the extension portion 11 can improve the overall stability of the racket when hitting the ball, and the vibration force generated by the racket hitting the ball is gradually transmitted to the tail to be eliminated, reducing the vibration force concentrated at the grip position of the outer handle body 2, and improving the vibration reduction effect.

[0041] Optionally, the outer surface of the outer handle body 2 is also wrapped with several circles of protective tape, which may be a plastic tape or a cloth tape, to protect the outer handle body 2 and the vibration damping body 3 and improve the grip feel of the handle.

[0042] Optionally, the inner handle body 1 is made of aluminum alloy, carbon fiber or titanium alloy, and the outer handle body 2 is made of ethylene-vinyl acetate copolymer, rubber, silicone, latex or polyurethane.

[0043] like Fig. 9 As shown, the utility model also provides a racket, comprising a racket board and the above-mentioned vibration-damping handle structure. When the vibration force generated by the racket board hitting the ball is transmitted to the vibration-damping handle structure, the vibration-damping body on the vibration-damping handle structure can absorb the vibration force on the inner handle body, and the symmetrically arranged vibration-damping bodies can offset the opposite vibration forces, thereby improving the vibration-damping effect of the racket and enhancing the user's hitting feel.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
