Description

Luminous badminton

Technical Field

The utility model relates to a luminous badminton belongs to cultural sports goods field.

Background

Badminton is a popular sports activity. Most people go to school on a daily basis, so that the time is long for doing exercises at night, and a special venue has few expensive fields and is inconvenient to transport, so that people feel inconvenient to play badminton to exercise the body.

There is a need for a shuttlecock that can be used by people at night in a dark or low light environment.

There are two types of light emitting shuttlecocks on the market today:

one is to dig a round hole at the feather end of the common badminton head and stick a light emitting module in the hole with glue. The module consists of a switch, a battery, an LED and a shell. When the badminton racket is used, the switch is pressed, the LED shines, and the skirt part behind the head of the badminton racket is illuminated. The luminescent badminton has the following disadvantages: one is that the added weight of the lighting module is too great relative to a standard shuttlecock. The flight speed of a standard shuttlecock is identified by the weight of the shuttlecock, which is commonly known as 49/50/51, corresponding to a weight of 4.9/5.0/5.1 grams. The weight of the light emitting module of the badminton light is about 3 g, so that the weight of the badminton is greatly increased, the flying speed is too high when the badminton is hit, and even professional athletes are difficult to hit. The other is that the light-emitting part is arranged at the rear part of the ball head, the lighting direction is irradiated to the ball skirt from the rear part of the ball head, and only the part of the ball skirt is lighted, so that when the golf ball is used at night, people can see the ball skirt by eyes, the judgment error is generated, and the hitting of the golf ball is more difficult.

Thirdly, when the badminton is struck, the switch is impacted, the situation of accidental disconnection occurs, and the use is influenced. In addition, the light-emitting module is integrally bonded on the bulb, the battery is difficult to replace, and the feather bulb is basically scrapped after the battery is used up after being used for several hours, so that waste is caused.

The other type of badminton is also characterized in that a luminous component is embedded in the rear part of the badminton head, a luminous body irradiates the inside of the badminton head, and the badminton head emits light. The luminous body consists of a flash control chip, a vibration switch, a battery and 3 LEDs. When the bulb is struck in use, the chip is triggered by the vibration switch, and the bulb starts to emit flickering light. Like the previous ball, this shuttlecock is heavier and the shock switch has directionality, i.e. the ball does not shine when the position and direction of the flap are inappropriate.

Patent No. 01258635.8 utility model patent "luminous shuttlecock" patent document discloses a luminous shuttlecock, as its patent document: "the utility model discloses a realize through following technical scheme: the cap is connected with the badminton bracket body and a lighting part is arranged between the cap and the badminton bracket body. "a conductive sheet for connecting the battery of the light emitting section is fixed to an appropriate place in the spherical cap". The "fixing of the conductive sheet for connecting the battery of the light emitting part to the proper place" shows that the patent does not disclose how to place and fix the light emitting part and the structure of the switch thereof, which is the key point for realizing a practical light emitting shuttlecock.
