Description
BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
[0001] The present invention generally relates to toy guns and,
more particularly, to a self-test fire control system for a toy gun
capable of preventing malfunction.
(b) Description of the Prior Art
[0002] Military simulation games are gaining popularity and various
types of replica weapons are developed and marketed, such as BB
guns, paintball guns, airsoft guns, etc. Based on their power, toy
guns may be categorized as airsoft guns, electrically powered guns,
and gas-powered guns. For electrically powered guns, electricity
powers mechanical parts (e.g., motor, gears) to compress spring and
to shoot pellets. Electrically powered guns usually involve
electronic control.
[0003] For toy guns with the electronic trigger is already
commercially available. They usually include a control module and a
power module for fire control. The components, i.e., motor, spring,
battery, and gears, are most difficult to control, and are most
susceptible to erroneous operation. Especially when one of the
components is replaced by the user, incompatibility between
components may occur, causing malfunction and power consumption.
Therefore tuning and adjustment is often required. For example, a
three-round burst fire may suffer unstable current from the battery
and adjustment to other components may be required.
SUMMARY OF THE INVENTION
[0004] A major objective of the present invention is to provide a
self-test fire control system for toy guns capable detecting the
compatibility between the motor, spring, battery, and gears, so as
to prevent malfunction and to enhance operation reliability.
[0005] The self-test fire control system includes a power unit and
a control unit connected to the power unit and configured with a
self-test software application. The power unit includes a power
module and a driver module. The control unit includes a voltage
monitor module, a regulator module, an indicator module, a fire
mode selection module, and a trigger ON/OFF module. Before the toy
gun is operated, the control unit may test the circuit switches,
the gear set, and the battery so as to see if there is an
incompatibility between or anomaly in the motor, spring, battery,
or gear set. As such, corrective actions or repairs may be
performed and the reliability of the toy gun is enhanced.
[0006] To provide different fire modes, the toy gun provides a fire
selection piece, an interrupted/burst mode microswitch, the trigger
microswitch, the interrupted mode microswitch, and the three-round
burst mode microswitch. The fire selection piece is engaged by a
control dial to move and drive the various microswitches so as to
operate the toy gun in different fire modes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] The following descriptions are exemplary embodiments only
and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0016] As shown in FIGS. 1 to 5, a self-test fire control system
for a toy gun 1 includes a power unit 2 and a control unit 3. The
control unit 3 is configured with a software application and is
connected to the power unit 2. The toy gun 1 includes a fire
selection piece 11, a safety block piece 12, a trigger 13, an
intenupted/burst mode control piece 14, an intenupted/burst mode
microswitch 15, a trigger microswitch 16, an interrupted mode
microswitch 17, a three-round burst mode microswitch 18, a motor
19, a gear set 20, a spring 21, and a battery 22. The electricity
stored in the battery 22 powers the motor 19 to compress the spring
21 through the gear set 20 so as to shoot pellets. The gear set 20
includes a cam 201 that may engage the interrupted/burst mode
control piece 14, which in turn presses against the
intenupted/burst mode microswitch 15. Whenever the gear set 20 has
made a turn, the interrupted/burst mode control piece 14 is engaged
once, and the interrupted/burst mode microswitch 15 is turned on
once.
[0017] The power unit 2 includes a power module 23 and a driver
module 24. The battery 22 is connected to the power module 23 for
providing electricity to the toy gun 1. The motor 19 is connected
to the driver module 24 for driving the motor 19. The driver module
24 includes a main Metal Oxide Semiconductor Field Effect
Transistor (MOSFET) 241 and an auxiliary MOSFET 242. The control
unit 3 includes a voltage monitor module 31, a regulator module 32,
an indicator module 33, a fire mode selection module 34, and a
trigger ON/OFF module 35. The voltage monitor module 31 and the
regulator module 32 are for monitoring and stably and economically
providing electrical voltage from the battery 22. The
interrupted/burst mode microswitch 15, the interrupted mode
microswitch 17, and the three-round burst mode micro switch 18 are
respectively connected to the fire mode selection module 34. The
trigger micro switch 16 is connected to the trigger ON/OFF module
35.
[0018] The fire selection piece 11 is engaged by a control dial to
move and drive the various microswitches such as the
interrupted/burst mode microswitch 15, the trigger microswitch 16,
the interrupted mode microswitch 17, and the three-round burst mode
microswitch 18 so as to operate the toy gun 1 in different fire
modes. Before firing, the control unit 2 tests the gear set 20, the
interrupted/burst mode microswitch 15, the trigger microswitch 16,
the interrupted mode microswitch 17, and the three-round burst mode
microswitch 18, and the battery 22, so as to detect whether there
is incompatibility between or malfunction in the motor 19, the
spring 21, and the battery 22. Therefore erroneous operation may be
prevented and required adjustment may be made, thereby enhancing
the reliability of the toy gun 1.
[0019] The operation of the present invention is described as
follows.
[0020] When the toy gun 1 is set in the safety mode, the fire
selection piece 11 is pushed to a foremost position, the safety
block piece 12 is raised, and the trigger 13 is stuck. The toy gun
1 therefore cannot be fired.
[0021] When the toy gun 1 is set in the interrupted mode, the fire
selection piece 11 is pushed to press the interrupted mode
microswitch 17, the safety block piece 12 is freed, and the trigger
13 is operable to engage the trigger switch 16, which sends a
signal to the control unit 3. The control unit 3 drives the gear
set 20 to make a turn, the interrupted/burst mode control piece 14
is engaged once, and the interrupted/burst mode microswitch 15 is
turned on once. The electricity is then cut off.
[0022] When the toy gun 1 is set in the three-round burst mode, the
fire selection piece 11 is pushed to press both the interrupted
mode microswitch 17 and the three-round burst mode microswitch 18,
the safety block piece 12 is freed, and the trigger 13 is operable
to engage the trigger switch 16, which sends a signal to the
control unit 3. The control unit 3 drives the gear set 20 to make a
turn, the interrupted/burst mode control piece 14 is engaged once,
and the interrupted/burst mode microswitch 15 is turned on once.
The electricity is then cut off after the control unit 3 repeats
the process three times.
[0023] When the toy gun 1 is set in the automatic fire mode, the
fire selection piece 11 retreats so that no microswitch is pressed,
the safety block piece 12 is freed, and the trigger 13 is operable
to engage the trigger switch 16, which sends a signal to the
control unit 3. The control unit 3 drives the gear set 20 to make a
turn, the interrupted/burst mode control piece 14 is engaged once,
and the interrupted/burst mode microswitch 15 is turned on once.
The electricity is not cut off until the trigger 13 releases and
the trigger microswitch 16.
[0024] As shown in FIGS. 6 and 7, the self-test performed by the
present embodiment is as follows.
[0025] To enter the test mode, the toy gun 1's upper and lower
parts are disassembled first. Under any fire mode except the safety
mode (i.e., the safety block piece 12 is in the safety position),
entering the test mode is achieved by pressing the trigger 13 and
then connecting the battery 22.
[0026] The control unit 3 first tests the voltage of the battery 22
and instructs the indicator module 33 to present voltage status.
For example, if the battery 22 is full, a green lamp is flashed at
two-second intervals and, if the battery 22 is low, a red lamp
stays on. If the trigger 13 is pressed, the control unit 3 drives
the motor 19 to turn the gear set 20.
[0027] Then, the control unit 3 tests the trigger microswitch 16
and instructs the indicator module 33 to present test result. For
example, if the microswitch 16 responds within five second, an
orange lamp stays on; otherwise, the green lamp is flashed at
ten-second intervals.
[0028] Then, when setting the toy gun 1 to the interrupted mode,
the control unit 3 tests if a correct mode switch signal is
received and instructs the indicator module 33 to present test
result. For example, if the correct mode switch signal is received
within ten seconds, the green lamp stays on; otherwise, the red
lamp stays on.
[0029] Then, when setting the toy gun 1 to the three-round burst
mode, the control unit 3 tests if a correct mode switch signal is
received and instructs the indicator module 33 to present test
result. For example, if the correct mode switch signal is received
within ten seconds, the green lamp stays on; otherwise, the red
lamp stays on.
[0030] The control unit 3 then tests the two MOSFETs 241 and 242.
If the MOSFETs are normal (e.g., not short-circuited), instructs
the indicator module 33 to present test result. For example, the
green lamp stays on; otherwise, the orange lamp stays on. If the
green lamp is on, the control unit 3 also triggers the motor 19 to
drive the gear set 20 to make a turn as a prompt.
[0031] Finally, the control unit 3 engages the motor 19 to drive
the gear set 20 to make turns and the indicator module 33 is
instructed to show that self-test is over by, for example, flashing
the green lamp. A user may press the trigger 13 once to exit the
self-test mode. The motor 19 drives the gear set 20 to turn three
times to acknowledge that the self-test is over. The user then may
assemble the upper and lower parts of the toy gun 1 and start using
the toy gun 1.
[0032] In the above self-test process, if there is some anomaly,
the control unit 3 determines the degree of severity and instructs
the indicator module 33 to present the anomaly differently. For
example, if the anomaly is related to the gear set 20, the motor
19, or the interrupted/burst mode control piece 14, the red lamp is
flashed, signaling that the anomaly is the most severe one. If the
anomaly is related to the two MOSFETs, the red lamp stays on,
signaling that the anomaly is less severe. If the anomaly is
related to the trigger 13, the orange lamp is flashed, signaling
that the anomaly is the least severe one. Prompted by these
indicator lights, the user should disconnect the battery 22 and
perform corrective action and repair.
[0033] In the above self-test process, to see if the spring 21 and
the gear set 20 are compatible, the control unit 3 determines the
interval that the interrupted/burst mode microswitch 15 is engaged
by the interrupted/burst mode control piece 14 when the gear set 20
makes a turn, and tests the rotation speed of the gear set 20 by
making the gear set 20 to turn several times. Then the spring 21 is
too tight if the rotational speed is too low, or the spring 21 is
too loose if the rotational speed is too high.
[0034] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the claims of the present invention.
