Description

Lighting badminton ball

The present invention relates to a lighting badminton ball, and more particularly, to a lighting badminton ball in which a switch embedded in a badminton ball is automatically contacted by lighting a head of a badminton ball with a badminton racket so that the built-in illuminator is lit for several seconds. will be.

A common badminton ball has a rubber band formed under a wing portion of a net shape formed by injection of a bird feather or synthetic resin, thereby firmly fixing the lower portion of the wing portion, and a head portion made of a hemispherical rubber elastic body under the rubber band. Attached.

When playing badminton using such a badminton ball, the badminton ball flying at a relatively high speed due to the badminton racket's hitting power is enough to enjoy the game in the daytime where the surrounding brightness is bright or equipped with lighting. When playing a game at night where there is no facility, it is not easy to visually recognize the badminton ball position.

In addition, in addition to the venue for large-scale events such as competitions, it is wasteful for ordinary users to install a lighting system for playing badminton games, which adds to the economic burden on the users.

In addition, there have been many applications in which a light emitter is applied to a badminton ball or a light emitting device is built-in. However, when the light emitter is applied, a visually sufficient effect is not obtained. The user must feel uncomfortable because the game must be performed in a turned on state, and even when the actual game is not in progress, the light emitting device is turned on, causing unnecessary power consumption.

In addition, there is a prior application to detect that the racket hit the badminton ball by using the vibration sensor, and to use the same to turn on the light emitting device, but because it is built in the sensor is very complicated to configure the price of the badminton ball It provides a direct cause of the increase, and because the driving power of the light emitting device uses the accumulated solar light, there is a problem of price increase by configuring a means for accumulating solar light, and the sunlight is not accumulated enough on cloudy days There is a problem that does not provide enough lighting to perform the game.

Therefore, the present invention is to solve such a problem (s), the purpose of the present invention is to incorporate a light emitting device in the head of the badminton ball, the light emitting device automatically for several seconds as the user hits the badminton ball with a racket To provide a light badminton ball to emit light.

FIG. 2 shows a circuit diagram of FIG. 1 (b), and FIG. 3 shows a coupling state diagram of the lighting badminton ball according to the present invention.

With reference to FIGS. 1 to 3 will be described in detail the badminton ball applied to the present invention.

The badminton ball applied to the present invention, as shown in FIG. 1 (c), is a net-shaped wing portion 100 formed by injection into a bird feather or synthetic resin, and a head portion 200 that is priced by a racket and , The lighting device 300 is installed between the head 200 and the wing 100.

In this case, the head part 200 is made of a flexible material (for example, transparent silicone) having elastic force so as to transmit light emitted from the lighting device 300 and at the same time obtain sufficient elasticity when it is priced by the racket. .

In addition, as shown in FIG. 1 (a), the head part 200 is provided with a coupling groove 201 to allow the lighting device 300 to be retracted.

On the other hand, the lighting device 300, as shown in Figure 1 (b) and 1 (d), the battery 302 is installed at a predetermined position of the printed circuit board 301 in the form of a disc, the printed circuit An illumination device 303 is provided at approximately the center of the substrate 301, and a switch 304 and an IC integrated circuit 305 electrically connected to the battery 302 are provided on the printed circuit board 301. In this case, the lighting device 300 is configured such that the constant voltage V + supplied from the battery 302 is sequentially supplied to the switch 304, the IC integrated circuit 305, and the lighting device 303.

In this case, referring to FIG. 2, the circuit configuration of the lighting device 300 will be described. The power input terminal Vdd of the IC integrated circuit 305 is connected to receive the constant voltage V + supplied from the battery 302. The ground terminal Vss is grounded to ground. In addition, the switch 304 which makes contact with the badminton ball as the racket triggers the operation of the lighting device 300 to switch the constant voltage V + is supplied to the trigger terminal TG of the IC integrated circuit 305. And a light emitting element (for example, a light emitting diode (LED), etc.) 303 supplies a constant voltage V + and is forward between the battery 302 and the output terminal OUT of the IC integrated circuit 305. Is connected.

On the other hand, the switch 304 is connected to either the battery 302 or the trigger terminal TG of the IC integrated circuit 305 which is supplied with a constant voltage (V +) as shown in FIG. The first support part 306 fused on the circuit board 301, the spring structure vibrator 307 of which one side part was joined to the first support part 306, and the state which is not in contact with this vibrator 307 A second electrode inserted into the furnace vibrator 307 and connected to the other of the battery 302 to which the constant voltage V + is supplied or the trigger terminal TG of the IC integrated circuit 305 and fused on the printed circuit board 301. The support part 308 is comprised. In this case, the second support part 308 is formed in the form of a double bent approximately the center portion is inserted into the vibrator 307 and fused to the printed circuit board 301.

Referring to the manufacturing process and operation principle of the subject innovation having such a configuration as follows.

After mounting the IC integrated circuit 305, the light emitting element 303, the switch 304 and the battery 302 on the plane of the printed circuit board 301, they are arranged in accordance with the connection relationship described above.

When the lighting device 300 manufactured as described above is adhesively fixed to the wing unit 100, and the head unit 200 is adhesively fixed to the wing unit 100 (see FIG. 3), the lighting unit 300 includes a head unit. It is fixed while being inserted into the coupling groove 201 of the (200).

When a badminton game is played using the badminton ball produced by the above process, as the player strikes the badminton ball with the racket, the remaining portion of the entire portion of the vibrator 310 that is not fused to the first support part 306 is inertia. By vibrating in the vertical direction or other direction, thereby causing the vibrator 307 is in contact with the second support portion 308 at least once or more.

When the vibrator 307 and the second support part 308 contact each other, the constant voltage V + supplied from the battery 302 is supplied to the trigger terminal TG of the IC integrated circuit 305 to trigger the IC integrated circuit 305. Accordingly, the output terminal OUT of the IC integrated circuit 305 outputs a control signal in a logic "low" state for a predetermined time. Accordingly, the light emitting device 303 may be configured to have a predetermined time (eg, 3) set in the IC integrated circuit 305 by a voltage level of a pulse signal of a predetermined period output from the output terminal OUT of the IC integrated circuit 305. -5 seconds). Thereafter, when a predetermined time elapses, an output signal having a logic “high” state is generated at the output terminal OUT of the IC integrated circuit 305 so that the light emitting device 303 is turned off. When the switch 304 contacts with the light emitting device 303 turned on, the IC integrated circuit 305 is triggered again to repeat the above-described process.

As a result, the light emitting element 303 is not turned on by the user's separate operation, but is turned off when the game is not in progress, and is triggered by this shock when the badminton ball is hit by the racket, and is lighted for several seconds. Do.

As a result, according to the shuttlecock having an illumination function according to the present invention the following advantage (s) occurs.

That is, the light emitting device is not flickered by a user's separate operation, but is turned off when the game is not in progress, and is triggered by this shock when the shuttlecock is hit by the racket and is lit for several seconds, which is convenient for use.
