Description

{NOCK FOR CROSSBOW ARROW}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crossbow arrow knuckle, and more particularly to a crossbow knuckle which can be reused by applying a rechargeable battery and is easy to charge.

Generally, a crossbow arrow comprises a shaft, an arrowhead, and a collar, and a nock is mounted at the rear end of the shaft. The shaft is formed of carbon fiber, glass fiber, or aluminum, and has a hollow tube shape with an empty space inside.

Conventional arrows could not see the trajectory of the arrows when they were used in places where there was no illumination at night, and they could not confirm whether the target was hit.

In order to solve these problems, Korean Registered Utility Model No. 320902 (Document 1) and No. 351661 (Document 2) are disclosed.

Document 1 discloses a luminous arrow designed to emit light and sound when an arrow is blown to make it easier to identify an arrow when shooting an arrow at night. When the arrow hits somewhere, its direction or movement There is a problem in safety because the trajectory can not be known.

Reference 2 discloses a battery charger that includes a push switch having a battery mounted inside a shaft and electrically connected to a battery and having a push button for turning on / off the power, protruding outside of the shaft, and a push button Discloses a light-emitting arrow including a light-emitting diode that flickers by operation.

However, according to Document 2, when the battery is consumed because the rechargeable battery is not used, it is necessary to discard the battery, so that the management cost is increased for the user.

Further, since the push switch has a complicated structure, when the arrow hits a hard target, the push switch tends to break, and when the water penetrates through the push button projected to the outside, the push switch does not operate.

In addition, since the brightness of the light emitting diode can not be set by the user, power consumption is high, and there is no blinking function, so it is difficult to track the flight trajectory in the rainy night or bright day.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a crossbow knob having a structure that is easy to charge while applying a rechargeable battery.

Another object of the present invention is to provide a crossbow knuckle which has good strength against external impact and does not infiltrate from the outside.

It is another object of the present invention to provide a crossbow arrow knob capable of easily setting the brightness or blink period of the LED at will.

Another object of the present invention is to provide a crossbow knuckle which is easy to track the flight trajectory during a rainy night or during the day by blinking in flight.

The above-described object is achieved by a sliding-type portable terminal comprising: a housing having a latching groove formed at a rear end thereof to which a protrusion of a bow is applied, an inlet formed at a front end thereof, A circuit board on which an LED and a control microcomputer are mounted and housed in the accommodation space; A pair of sensing sensors mounted on one surface of the circuit board; A pair of charging terminals mounted to protrude from the other surface of the circuit board; And a rechargeable battery electrically connected to the circuit board, wherein the sensing sensor operates in an electrostatic manner to cause the sensing sensor to generate a sensing signal as the human body contacts the housing, And the battery is charged by being exposed to the outside of the housing.

Preferably, each of the detection sensors is disposed on the circuit board so as to be closest to the inner wall of the accommodation space.

Preferably, a portion of the battery protrudes from a front end of the housing, and a portion of the housing that receives the battery is coupled to a shaft of the crossbow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is an external view showing a crossbow arrow knuckle according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view.

The knuckle 100 includes a housing 110, a circuit board 140 on which the LED 120 is mounted, sensing sensors 160 and 162, a charging terminal 170, and a rechargeable battery 130, Fit to the rear end of the shaft and fix it.

In the housing 110,

The housing 110 is made of transparent or semitransparent plastic material so that light output from the LED 120 accommodated in the housing 110 is transmitted to the outside.

A housing space 111 is formed in the rear end of the housing 110 to receive a protrusion of the bow and an inlet 114 communicating with the housing space 112 is formed in front of the housing space, A part of the protrusion 130 may protrude, but the present invention is not limited thereto.

Openings 115 are formed on opposite opposite sides of the housing 110 so that the charging terminals 170 are exposed through the openings 115 as described later.

The accommodation space 112 is formed in a shape capable of accommodating the circuit board 140 and the sensing sensors 160 and 162 and the battery 130 mounted on the circuit board 140. In particular, The receiving space 112 is formed so as to be closest to the inner wall of the receiving space 112.

As shown in FIG. 1, the housing 110 and the battery 130 are mounted on the housing space 112 by pairs of the same shape. Then, the housing 110 is bonded to each other by, for example, ultrasonic welding.

By this sealing, the housing 110 is sealed so that water or foreign matter does not flow into the accommodation space 112 from the outside.

A portion of the housing 110 corresponding to the portion in which the battery 130 is accommodated may constitute an insertion portion 113 and may be forcibly press-fitted into the rear end of the shaft and coupled to the arrow. Alternatively, Can be combined.

The circuit board (140)

A microcomputer 150 for controlling the LED 120 and the battery 130 and a pair of the sensors 160 and 162 are mounted on the upper surface of the circuit board 140 so as to be spaced apart from each other. A charging terminal 170 for charging is protruded.

The sensing sensors 160 and 162,

The sensing sensors 160 and 162 are installed on the upper surface of the circuit board 140 such that the sensing sensors 160 and 162 are positioned nearest to the inner walls of the accommodation space 112, ).

When the user's hand touches the housing 110 from the outside of the housing 110, the sensing sensors 160 and 162 operate in an electrostatic manner, and the sensing sensors 160 and 162 sense the sensed signals, 140).

Preferably, the sensing sensors 160 and 162 can be projected onto the circuit board 140 in a columnar shape to secure a sufficient sensing area.

The charging terminal 170,

The charging terminal 170 protrudes from the lower surface of the circuit board 140 and is exposed to the outside through the opening 115 of the housing 110 as described above.

According to this structure, since the charging terminal 170 is in electrical contact with the power supply terminal of the cradle, charging can be started automatically only when the charging terminal 170 is mounted on the cradle storing the knock 100, .

The charging terminal 170 is spaced apart from the charging terminal 170. The charging terminal 170 may be formed as a structure having a proper shape except a portion directly in contact with the power supply terminal of the cradle so that the battery 130 can be inserted and fixed between the separated portions.

The battery 130,

The battery 130 may be charged and may be electrically connected to the circuit board 140 directly or by using a wire.

According to this structure, it is possible to apply a rechargeable battery to the crossbow arrow knob 100, and at the same time provide a structure that is easy to be charged, thereby improving user convenience and economical efficiency.

The microcomputer 150,

The microcomputer 150 incorporates a program for controlling the LED 120 and the battery 130.

3 is a block diagram showing the functional configuration of the control microcomputer.

The input unit 152 transmits a sensing signal pattern input from the pair of sensing sensors 160 and 162 to the controller 151. [

The pattern analyzer 153 compares the input sensed signal pattern with the reference sensed signal pattern stored in the memory 155 under the control of the controller 151 to check what kind of command is input.

The sensing signal pattern can be variously defined, for example, but not limited to, the following:

When the outer surface of the housing 110 corresponding to the pair of detection sensors 160 and 162 is kept in contact for a predetermined time, for example, three seconds, by the user's operation, the LED is recognized as an ON command.

In addition, the LED blinking period can be adjusted when the user touches the detection sensor 162 while maintaining contact with the detection sensor 160 among the detection sensors 160 and 162, for example. For example, the flicker cycle can be increased in proportion to the number of times the button is hit.

Conversely, if the sensing sensor 160 is touched while maintaining contact with the sensing sensor 162, the LED brightness can be adjusted. For example, the LED brightness may be increased in proportion to the number of times the LED is turned on.

In addition, if the detection sensors 160 and 162 are tapped simultaneously three times, the LEDs can be set to be turned off.

Therefore, the brightness and the lighting period of the LED can be easily set by the user, thereby improving the user's convenience.

On the other hand, it is possible to simply turn the LED 120 on and off. However, in a situation where the field of view is not sufficiently secured as in a rainy night, the LED 120 may be blinked to facilitate tracing of the flight path.

For this purpose, the flashing mode can be turned on and off by appropriately adjusting the contact pattern for the sensors 160 and 162, for example.

The control unit 151 can check the type of the instruction by the pattern analyzer 153 and control the LED driver 154 to control the LED 120 to be turned on or off or change the flashing period or brightness.

The charging unit 156 can charge the battery 130 under the control of the control unit 151. [ For example, when the cradle alarm 100 is mounted and the charging terminal 170 contacts the power supply terminal of the cradle, the controller 151 charges the battery 130 and stops charging when the battery voltage reaches 4.2V.

The acceleration sensing unit 157 senses the acceleration force when the arrow equipped with the knuckle 100 leaves the prototype and transmits the sensed acceleration to the control unit 151. When the impact sensor 158 receives an impact And transmits it to the control unit 151.

The control unit 151 controls the LED driving unit 154 according to the predetermined setting so as to cause the LED 120 to blink in a short cycle, Upon receiving the sensing signal, the LED driving unit 154 is controlled to cause the LED 120 to blink in a long cycle to prevent the battery 130 from being consumed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Accordingly, the scope of the present invention should not be construed as being limited to the embodiments described above, but should be construed in accordance with the following claims.
