Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ball sports, and in particular to a badminton ball body. Background Art
[0002] Badminton is an indoor sport that combines strength, speed and skill. It uses a long-handled net racket to hit a small ball made of feathers and cork. The sport originated in Japan in the 14th and 15th centuries, but modern badminton originated in India and was formed in the UK. In 1875, badminton officially appeared. In 1893, the first badminton association was established in the UK, which stipulated the requirements for the venue and the standards of the sport.
[0003] Badminton is an indoor sport in which a small ball made of feathers and cork is hit with a long-handled net racket across a net. Badminton matches are played on a rectangular court with a net in the middle. Both sides use various serving, hitting and moving techniques and tactics to hit the ball back and forth over the net. The winner is the one who prevents the ball from falling into the effective area of the team or causes the opponent to make a mistake.
[0004] The existing badminton will inevitably be hit on the body of the badminton when being hit by the racket. Since the thickness of natural feathers and artificial nylon is too thin, the flexibility and shock absorption are poor, which easily leads to the breakage or tearing of feathers. The production technology requirements of badminton are very high. It is also inevitable that the head of the badminton is easy to fall off due to factors such as the uneven cutting of feather shapes during the production process or the irregular arrangement of feathers when inserted on the head, or the body of the nylon badminton is buckled on the head of the badminton. The durability and flight stability of the badminton are also greatly reduced, which directly affects the ball feeling and experience of the athletes. For this reason, we propose a badminton body. Utility Model Content
[0005] The utility model provides a badminton body, which solves the problems in the prior art that natural feather and artificial nylon badmintons are too thin, have poor flexibility and shock absorption, are easily caused to break feathers or tear nylon, and have poor hitting resistance and flight stability.
[0006] The technical solution of the utility model is as follows: a badminton ball body, including a ball body main body, one side of the ball body main body along the central axis is a ball head connection area, the other side of the central axis is a ball tail area, the ball head connection area is provided with a protrusion, the ball tail area is provided with a circle of triangular ball skirt leaves with the central axis as the center of the circle circumference, the area of the ball body main body close to the ball tail area is evenly distributed with two circles of main ventilation openings with the central axis as the center of the circle circumference, the area of the ball body main body close to the ball head connection area is evenly distributed with the central axis as the center of the circle circumference, and the main ventilation openings and the auxiliary ventilation openings are inclined along the central axis direction of the ball body main body.
[0007] Preferably, the ball body is made of EVA material.
[0008] Preferably, the number of the main ventilation openings in each circle is 12.
[0009] Preferably, the number of auxiliary ventilation openings in a circle is 6.
[0010] Preferably, the wall thickness of the ball head connection area is 3 mm, the wall thickness of the ball tail area is 2 mm, and the wall thickness of the ball head connection area decreases toward the wall thickness of the ball tail area.
[0011] Preferably, the two inner side walls of the main ventilation opening and the auxiliary ventilation opening inclined along the central axis direction of the ball body are both configured to be sloped.
[0012] The working principle and beneficial effects of the utility model are:
[0013] 1. In the utility model, since the ball body is integrally formed and made of EVA material, which is a foamable material with the advantages of strong flexibility, good impact resistance and low density, the weight can be kept within the standard range and the volume is larger, so that the ball body is thicker than the prior art, and the part close to the ball head is 3mm thickest and decreases to 2mm at the ball tail, which greatly improves the situation of broken hair in ordinary badminton and too thin and easy tearing of nylon badminton, thereby enhancing the durability.
[0014] 2. In the utility model, since the main vent and the auxiliary vent are arranged on the main body of the ball, and both the main vent and the auxiliary vent are inclined along the length direction of the main body of the ball, the badminton can effectively improve the unstable flight and inaccurate landing position caused by the heavy tail of the ball or the influence of air resistance during flight, and the contact area with the air is smaller, the resistance is reduced, and the ball body rotates in one direction, so the flight is more stable. Because the rotating object has rotational inertia, the rotation axis can more stably point to a fixed direction. While the ball body rotates, the speed of the ball will gradually decrease due to the rotation of the ball body, so that the flying distance is too long due to the excessive speed of the ball.

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figure 1 to Figure 7As shown, this embodiment proposes a badminton ball body, including a ball body main body 1, one side of the ball body main body 1 along the central axis is a ball head connection area 100, and the other side of the central axis is a ball tail area 200, and the ball head connection area 100 is provided with a protrusion 2. In this embodiment, the protrusion 2 is preferably set to a solid cone shape, so that the subsequent contact area between the ball body main body 1 and the ball head can be larger, and it is also easier to reinforce the ball body main body 1 and the ball head with glue, further avoiding the occurrence of the ball head falling off.
[0028] Since the large ventilation holes of the current badminton in the prior art are generally arranged near the ball head, and the ball tail is a relatively thin skirt, this will cause the center of gravity of the badminton to be mainly at the ball head position. Under the balancing effect of the complete skirt, the badminton will fly more balanced and smooth when hit. However, once the skirt is partially damaged or damaged, there will be obvious unstable flying when hitting, which also leads to a short service life of the current badminton. The feather material and nylon material are very easy to be damaged when hit because they are relatively thin, which is also one of the main reasons for the short service life of the badminton in the prior art.
[0029] In this embodiment, a circle of triangular ball skirt leaves 3 is arranged in the ball tail area 200 with the central axis as the center of the circle, two circles of main vents 4 are evenly distributed in the area of the ball body 1 near the ball tail area 200 with the central axis as the center of the circle, and a circle of auxiliary vents 5 is evenly distributed in the area of the ball body 1 near the ball head connection area 100 with the central axis as the center of the circle. The main vents 4 and the auxiliary vents 5 are inclined along the central axis of the ball body 1. In a preferred embodiment, the central axis of the ball body 1 is set as the a-axis 7, the inclination direction of the main vents 4 and the auxiliary vents 5 is the b-axis 8, and the angle between the a-axis 7 and the b-axis 8 is 10 degrees. Figure 4 As shown, in the present embodiment, the number of main vents 4 in each circle is 12, 24 main vents 4 in total, and the number of auxiliary vents 5 in one circle is 6. The main vents 4 are slightly larger, and the auxiliary vents 5 are slightly smaller. Such a design can effectively improve the unstable flight and inaccurate landing position of the badminton caused by the heavy tail of the ball or the influence of air resistance during flight. The contact area with the air is smaller, the resistance is reduced, and the ball body rotates in one direction, thereby making the flight more stable. Because a rotating object has rotational inertia, the axis of rotation can more stably point to a fixed direction. While the ball body rotates, the speed of the ball will gradually decrease due to the rotation of the ball body, which can avoid the flying distance being too long due to the excessive speed of the ball.
[0030] In this embodiment, the ball body 1 is made of EVA material, the wall thickness of the ball head connection area 100 is 3mm, the wall thickness of the ball tail area 200 is 2mm, and the wall thickness of the ball head connection area 100 decreases toward the wall thickness of the ball tail area 200 (such as Figure 3(as shown in the cross-sectional changes of the partial section inside), in this embodiment, the ball body 1 is integrally formed of EVA material, and is made of EVA material by heating and pressurizing an injection-type EVA foaming machine. The EVA material itself is a foamable material and has the advantages of strong flexibility, good impact resistance and low density. In this way, the weight can be kept within the standard range and the volume is larger, so the one-piece ball body can be thickened, and the part close to the ball head is 3mm thickest, and then decreases to 2mm at the ball tail. In this way, the situation of broken hair of ordinary badminton and too thin and easy tearing of nylon badminton can be greatly improved, thereby enhancing the durability of the ball. At the same time, the EVA material is also a material that can be glued more firmly.
[0031] Considering that the ball body 1 in this embodiment is thicker than the wall thickness of conventional feather shuttlecocks and nylon shuttlecocks, Figure 6 As shown (for ease of understanding, the figure only shows the cross-sectional state of opening one hole), if a hole (main vent 4, auxiliary vent 5) is opened vertically toward the central axis in the wall thickness of the spherical body 1, the inner wall of the hole will be thicker, and the two inner side walls of the main vent 4 and the auxiliary vent 5 inclined along the central axis of the spherical body 1 are both set as air inlet surfaces 9. The two air inlet surfaces 9 facing the central axis will have a certain wind resistance. Therefore, in order to further reduce the wind resistance and assist the spherical body 1 to rotate, the two inner side walls of the main vent 4 and the auxiliary vent 5 inclined along the central axis of the spherical body 1 are both set as slope shapes 6, and the inclination direction of the slope shape 6 conforms to the inclination direction of the main vent 4 and the auxiliary vent 5, as shown in FIG. Figure 7 As shown (for ease of understanding, the figure only shows the cross-sectional state of opening one hole), that is, the two air inlet surfaces 9 are not facing the central axis, but are inclined.
[0032] To sum up, in this embodiment, by changing the ball body 1 to a material that can be more firmly adhered by glue and increasing the contact area between the ball body and the ball head, the ball head becomes less likely to fall off. At the same time, an integrated ball body is used and the ball body 1 is thickened, so that the ball body 1 has better flexibility and impact resistance, thereby enhancing the hitting resistance of the ball body 1. It effectively improves the situation of unstable flight and displacement of the landing point of ordinary badminton due to factors such as uneven feather sizes, uneven arrangement, breakage of feathers during hitting, and tearing of nylon balls due to being too thin. Compared with existing natural material badminton or nylon material badminton, it has more outstanding performance in hitting resistance and flight stability.
[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
