Abstract
The invention provides a gear box device, which improves the performance, reduces the vibration and the noise, and improves the use feeling and the convenience of a user for an air gun using a motor. The gear box device is arranged on an air gun and is provided with: a motor; a deceleration section that reduces a rotation speed of the motor and transmits power of the motor to a bullet firing section that fires a bullet; and a housing unit in which the motor and the speed reduction unit are housed, wherein the motor is provided such that a motor rotation shaft, which is a rotation shaft of the motor, is perpendicular to a longitudinal direction of a barrel of the air gun.
Description
Technical Field
The present invention relates to a gear box device and an air gun as a toy gun equipped with the gear box device.
Background
An air gun as a toy gun uses a piston to compress air in a cylinder and fire a bullet. An air gun is known that is driven by transmitting power of a motor when driving the piston.
(problem 1)
For example, as shown in fig. 44 and the like of patent document 1, there is a conventional air gun in which a motor is disposed on a grip. The power of the motor disposed on the grip is transmitted to the piston disposed outside the grip via the speed reduction mechanism, thereby driving the piston.
However, if the motor is incorporated in the grip in this manner, the grip with the motor is limited to the grip with the motor when the user wants to replace the grip according to the preference of the user, and the degree of freedom of the user is greatly reduced.
Further, since the attachment angle of the grip is fixed, the attachment angle of the grip cannot be changed according to the preference of the user.
Further, when the motor is rotated, a reaction torque is generated about the rotation axis of the motor inserted into the grip, and therefore, the performance of the air gun or the feeling of use of the user may be impaired, for example, the gun may be shaken in the left-right direction or the grip may be held with a feeling of discomfort.
As another conventional air gun, as shown in fig. 1 of patent document 2, there is a configuration in which a motor is not built in a grip, and the motor and a gear train are disposed adjacent to each other.
However, since the motor of patent document 2 is arranged such that the rotation axis of the motor is parallel to the longitudinal direction of the gun barrel, when the motor rotates, a reaction torque in the rolling direction about the longitudinal direction of the gun barrel as an axis is generated, and thus, as in patent document 1, there is a possibility that the performance of the air gun or the feeling of use of the user is impaired, such as the gun shaking left and right or the feeling of holding the grip being uncomfortable.
(problem 2)
In either of patent document 1 and patent document 2, since the motor rotation shaft is orthogonal to the rotation shaft of the gear of the speed reduction unit that drives the piston, the direction of the rotation shaft needs to be changed at any stage of the speed reduction unit. For example, a transmission mechanism such as a bevel gear (bevel gear) is employed on the input side of the speed reducer unit, and rotation is transmitted between two orthogonal shafts.
However, in the case of such a transmission mechanism, when a backlash occurs in the thrust (thrust) direction of the motor due to long-term use of the gun or deterioration of the gun with time, there is a problem that the transmission efficiency is remarkably deteriorated or vibration, noise, and abrasion become large due to the backlash.
(problem 3)
Further, there is an air gun in which the gear box device as in patent document 1 can be completely separated from the air gun body. If the gear box device can be completely separated from the air gun body, the mechanism of the speed reducer can be easily replaced or repaired.
However, since the motor and the gear box are independent from each other, the motor needs to be detached when the gear box device is detached from the air gun body, and when the gear box device is reassembled to the air gun, it takes time to adjust the engagement between the motor and the gear of the reduction unit, or to perform precise adjustment such that a backlash (backlash) when the motor and the gear are engaged is appropriate, and the like, it is not possible to say that the convenience is certainly good.

The technical problem described in the technical problem to be solved by the present invention is not a known technical problem, but a technical problem which the present inventors have found alone is a fact that the invention is the same as the configuration and method of the present invention.
(1) The air gun of the present embodiment has an integral structure
The structure of the air gun 1 of the present embodiment will be explained.
Fig. 1 shows the internal configuration of the main part of an air gun 1 as a toy gun simulating an Assault Rifle (Assault Rifle). The air gun 1 has a barrel 11, a front grip 12, an upper gate 13, a lower gate 14, a grip 15, and a magazine 16.
The gun barrel 11 has an elongated cylindrical shape and guides a bullet fired from a bullet firing section 20, which will be described later, to the muzzle of the gun by passing the bullet through the gun barrel. The barrel 11 is also known as a tube or barrel.
The front grip 12 is the part that encases the barrel. The user supports the air gun 1 by holding the front grip 12 with one hand. In a real rifle, the front grip 12 also has the effect of protecting the hand from the heat of the barrel. The front handle 12 is also known as a front support, front grip (forehand), and fender (Hand guard).
The upper gate 13 is a frame that houses a bullet emitting section 20 described later.
The lower brake 14 is a frame that houses a gear box device 100 described later.
The upper gate 13 and the lower gate 14 are joined by any joining means such as a fixing pin, and can be separated by removing the fixing pin.
The grip 15 is provided to support the air gun by being held by a hand opposite to the hand holding the front grip 12, and is used to pull a trigger (trigger).
The magazine 16 is a magazine that stores a plurality of cartridges and supplies the cartridges to the loading section L of the cartridge firing section 20.
The gear box device 100 is composed of a motor 101, a speed reduction unit 102, and a housing unit 103 housing the motor 101 and the speed reduction unit 102, and is a device that transmits power of the motor 101 to the bullet emitting unit 20. The details of the gear box device 100 will be described later with reference to fig. 2 to 5.
The bullet firing section 20 includes a piston 21, a cylinder 22, and a compression spring 23, and fires a bullet by the power of the gear box device 100.
The piston 21 has a rack 24 that receives power from the gearbox apparatus 100. Specifically, the rack 24 is engaged with a drive gear 102d of the speed reducer unit 102 described later, and converts the rotational motion of the drive gear 102d into the translational motion of the piston 21.
In the present embodiment, the air gun 1 includes the gear box device 100, but instead, the motor 101 and the reduction unit 102 may be provided directly on the under gate 14.
(2) Gear box device of the present embodiment
A gearbox device 100 according to an embodiment of the present invention will be described with reference to fig. 2 to 5.
As shown in fig. 2 to 5, the gear box device 100 includes a motor 101, a reduction unit 102, a housing unit 103, and a control board 104.
a. Motor 101
The motor 101 converts electric energy supplied from a battery, not shown, into mechanical energy, thereby generating motive power in the form of rotational motion.
The type of the motor 101 is not limited, but a brushless motor is particularly preferably used. The brushless motor is a motor that rotates a rotor formed of a magnet by a magnetic field formed by a current flowing through a winding of a stator, and rotation is controlled by changing a current value using a drive circuit (motor driver) formed of power elements such as transistors provided on the control board 104.
In this way, since the brushless motor rotates the magnet that does not require power supply, instead of rotating the winding, it is possible to reduce the size of the rotating rotor, thereby achieving reduction in thickness, size, and weight. As a result, the reduction unit 102 can be compactly stored in the storage unit 103, and the gear box device 100 itself can be downsized. As will be described later, the rotation shaft of the motor 101 is easily set to be perpendicular to the longitudinal direction of the gun barrel of the air gun 1.
Further, the brushless motor does not require a brush or a commutator as a consumable part such as a brush motor, and therefore has a long life and high reliability.
Further, since the brushless motor controls the current flowing through the winding of the stator by a control board such as a motor driver, various operation settings such as rotation and stop, and power change can be performed.
In the present embodiment, the motor 101 is provided such that the rotation axis of the motor 101 is perpendicular to the longitudinal direction of the barrel 11 of the air gun 1. That is, in fig. 1, the rotation axis MA of the motor 101 constituting the gear box device 100 is orthogonal to the center line F of the gun barrel. In this case, the rotation axis MA is also orthogonal to the vertical direction. In addition, the rotation axis MA is parallel with respect to the horizontal plane (ground).
Since the rotation axis MA of the motor 101 is perpendicular to the longitudinal direction of the barrel 11, a reaction torque in the rotation direction about the rotation axis MA is generated. The reaction torque in such a direction can be easily absorbed by the user gripping the grip 15 and the front grip 12. According to the arrangement of the motor 101 as in the present embodiment, the offset in the left-right direction due to the reaction torque in the rotational direction around the long axis of the grip 15 or the rotational direction around the long axis of the gun barrel 11 as in the conventional case does not occur.
Further, in the present embodiment, as shown in fig. 1, the gear box device 100 including the motor 101 is disposed between the grip 15 and the front grip 12 at a position in the longitudinal direction of the gun barrel 11, and the grip 15 is located behind the trigger of the air gun 1. As a result, since the sum of the torques generated by the reaction forces received from the hands gripping the grip 15 and the front grip 12 is in the opposite direction to the reaction torque generated in the air gun 1 by the rotation of the motor 101, the reaction torque of the motor 101 can be easily absorbed by the user gripping the grip 15 and the front grip 12.
In the case of the air gun 1 without the front grip 12, the gear box device 100 may be provided at a position between the grip 15 and the gun barrel 11.
In the present embodiment, the rotation direction of the motor 101 is arbitrary, and may be rotated in a direction in which a reaction torque generated by the rotation of the motor 101 acts in a direction to push up the tip of the gun barrel 11. In fig. 1 and 2, the rotation axis MA rotates rightward (clockwise) in the plane of fig. 1 and 2. Since the reaction torque acts in such a direction, the same feeling as that of a real gun can be reproduced.
Conversely, the gun barrel may be rotated in a direction in which a reaction torque generated by the rotation of the motor 101 acts in a direction of pressing down the front end of the gun barrel 11. In fig. 1 and 2, the rotation axis MA rotates leftward (counterclockwise) in the paper plane of fig. 1 and 2. In this case, since the rotation direction of the drive gear 102d is reversed to mesh with the rack 24, the intermediate gear 102b may be omitted or one additional intermediate gear may be added in addition to the intermediate gear 102 b.
In any direction, the direction can be determined according to the preference of the user.
The rotation speed of the motor 101 may be controlled to be slow at the start of rotation, gradually increased to maintain a constant speed, gradually decreased toward the end of rotation, and finally stopped. The velocity gradient may be linear or exponential. By performing such control, it is possible to suppress the generation of the reaction torque without damaging the gears constituting the speed reducer section 102.
b. Deceleration section 102
The power of the motor 101 is input to the reduction unit 102. The decelerating section 102 reduces the rotation speed of the motor 101 and transmits the power of the motor 101 to the bullet firing section 20.
In the present embodiment, the reduction unit 102 includes an input gear 102a, an intermediate gear 102b, an output gear 102c, and a drive gear 102 d.
The rotation shaft of the input gear 102a is coupled to the motor 101 coaxially with the motor shaft MA, and is directly rotated and driven by the motor 101.
The intermediate gear 102b is composed of two gears, a large-diameter gear and a small-diameter gear, and the rotational speed of the intermediate gear 102b is reduced by a reduction ratio determined by the gear ratio between the large-diameter gear and the input gear 102 a.
The output gear 102c is also composed of two gears, a large diameter gear and a small diameter gear, and the rotation speed of the intermediate gear 102b is reduced by a reduction ratio determined by the gear ratio of the large diameter gear of the output gear 102c and the small diameter gear of the intermediate gear 102 b.
Therefore, in the reduction unit 102, the rotation speed of the motor 101 can be greatly reduced while the configuration is compact by reduction between the input gear 102a and the intermediate gear 102b and reduction between the intermediate gear 102b and the output gear 102 c.
The drive gear 102d is a gear that is connected to the output gear 102c via a planetary gear and rotates in the opposite direction to the output gear 102 c. The drive gear 102d meshes with the rack 24 of the piston 21, and the rotational motion of the counterclockwise drive gear 102d is converted into a linear motion in which the piston 21 moves in the left direction in fig. 1 and 2. Further, since the output of the output gear 102c is further decelerated due to the planetary gear.
Fig. 3 is a side view seen from a direction a of the gear box device of fig. 2, and fig. 4 is a perspective view seen from a direction B of the gear box device of fig. 3.
As shown in fig. 3 and 4, the drive gear 102d has a toothed portion T and a non-toothed portion N on the outer peripheral portion thereof, the toothed portion T having teeth as teeth, and the non-toothed portion N having no teeth.
When the toothed portion T of the drive gear 102d and the rack 24 of the piston 21 face each other, the toothed portion T meshes with the rack 24 of the piston 21, and therefore the output torque of the speed reducer portion 102 is transmitted as a driving force to the rack 24 of the piston 21 via the toothed portion T of the drive gear 102 d.
On the other hand, when the drive gear 102d rotates and the non-toothed portion N faces the rack 24, the piston 21 is free from the drive gear 102d, and therefore the output torque of the speed reducer 102 is not transmitted to the rack 24. Accordingly, the piston 21 is moved rightward by the compression force of the compression spring 23.
By providing the drive gear 102d with the toothed portion T and the non-toothed portion N in this way, desired movement of the piston 21 in the left-right direction can be achieved.
However, as shown in fig. 2, the rotation axis MA of the motor 101, the rotation axes of the input gear 102a, the intermediate gear 102b, and the output gear 102c are parallel to each other and in a direction perpendicular to the plane of fig. 2. Therefore, the rotation axes of all the gears of the reduction part 102 are parallel to the rotation axis MA of the motor 101.
In particular, since the rotation axis MA of the motor 101 is parallel to the rotation axis of the input gear 102a, it is not necessary to use a conventional transmission mechanism for transmitting rotation between two non-parallel shafts, such as meshing of bevel gears. That is, a Spur Gear (Spur Gear) can be used as the Gear of the input Gear 102a that meshes with the motor 101. In the case where the gear is a spur gear, even when the motor is loosened in the thrust direction due to long-term use of the gun or deterioration of the gun over time, the looseness in the thrust direction can be absorbed without transmitting the thrust force. Therefore, unlike the conventional technique using a bevel gear, vibration, noise, and abrasion can be reduced without lowering the transmission efficiency of the speed reducer 102.
In addition, since the rotation axes of the plurality of gears constituting the speed reducer section 102 are all parallel, all or a part of the reaction torque generated by each gear can be cancelled out.
In addition, the reduction unit 102 may use a sliding contact transmission using a cam or the like, a rolling contact transmission using a friction wheel or the like, or a transmission using a belt or a pulley, in addition to a transmission via a gear.
c. Receiving part 103
The housing unit 103 houses the motor 101 and the reduction unit 102.
Since the housing unit 103 houses the motor 101 and the reduction unit 102, the gear box device 100 can include both the motor 101 and the reduction unit 102. That is, the gear box device 100 can include the entire power transmission system for transmitting power to the bullet emitting portion 20.
Therefore, since the motor 101 is built in, it is not necessary to provide a space separately in other parts.
For example, since a special structure in which a space for housing the motor 101 is provided in the grip 15 is not required, the shape, design, angle, and weight of the grip 15 can be freely changed according to the preference of the user. In addition, the grip 15 may be a grip of a real gun.
In the present embodiment, the motor 101 is provided in contact with the housing 103. Specifically, the rear surface of the motor 101 is disposed in contact with the housing 103. If the housing 103 is made of a material having high thermal conductivity, such as an aluminum alloy or a zinc alloy, the housing 103 can function as a heat sink (heatsink) to prevent overheating of the motor 101. The heat of the housing 103 can be released to the outside through the lower gate 14.
Such a configuration is particularly preferable when a brushless motor is used as the motor 101. Since the winding of the stator is provided in contact with the rear surface of the motor, the brushless motor can efficiently discharge heat via the housing 103.
The material constituting the housing 103 can be selected from any material such as plastic and metal. When made of metal, the metal can be manufactured by casting such as die casting or forging.
The gearbox assembly 100 is removable from the air gun 1. In the case of the present embodiment, since the gear box device 100 has the housing section 103, the gear box device 100 is configured as 1 independent device and can be easily attached and detached.
For example, when the gearbox device 100 is detached from the air gun 1, the upper gate 13 and the lower gate 14 are separated, and the gearbox device 100 is drawn out from the lower gate 14.
For example, when the gear box device 100 is assembled to the air gun 1, the gear box device 100 is fitted into a space provided in the lower gate 14. In this case, since the motor is not provided in the grip 15 as in the conventional case, it is not necessary to adjust the position of the gear box device 100. Then, the upper gate 13 and the lower gate 14 are combined.
Since the gear box device 100 can be attached to and detached from the air gun 1 in this manner, replacement and repair of the gear box device 100 can be easily performed.
Further, since the gear box device 100 including the motor 101 and the reduction unit 102 can be attached and detached as a single unit, the gear box device 100 can be easily attached and detached without requiring a work of engaging gears of the motor and the reduction unit when attaching the gear box device to the air gun.
Further, the gear box device 100 may be replaced with a gear box device of a conventional air gun. When the gear box device 100 is mounted in a space of the gear box device of the conventional air gun and an electric wire for supplying a power source from a battery is connected, the conventional air gun can be used without using a motor originally provided in the conventional air gun.
d. Control substrate 104
The gearbox device 100 has a control board 104 for controlling the motor 101. The control board 104 is mounted on at least one surface of the housing 103.
In the present embodiment, as shown in fig. 5, the control board 104 is mounted on the back surface of the housing 103.
Since the motor 101 is housed in the housing portion 103, the control board 104 is also mounted on the back surface of the housing portion 103 close to the motor 101, so that the signal lines, the power lines, and the like can be shortened, and the reliability can be improved. Further, the entire power transmission system for transmitting power to the bullet emitting portion 20 including the control board 104 can be compactly integrated in the gear box device 100.
Further, since the control board 104 is included and is compactly collected in the gear box device 100, a wider space for the battery can be secured, and the operating time of the air gun can be extended. Specifically, the control board 104 and the battery are provided in the rear pipe provided at the rear portion of the conventional upper brake 13, but the control board 104 may be provided integrally with the gear box device 100, and the entire rear pipe may be used as a space for the battery.
In the present embodiment, the control board 104 and the housing 103 are provided in contact with each other. If the housing 103 is made of a material having high thermal conductivity, such as an aluminum alloy or a zinc alloy, the housing 103 can function as a heat sink and dissipate heat generated by the control board 104. With this configuration, it is possible to prevent the control board 104 from overheating and causing a failure.
The control board 104 may be mounted on the front surface, the side surface, or the bottom surface of the housing 103 instead of being mounted on the back surface of the housing 103. Further, the housing unit 103 may be mounted so as to straddle both the back surface and the side surface, or both the back surface and the bottom surface.
The user can change the control method of the motor 101 by the control board 104 through a user interface not shown. The user can change the delay time from the instruction of the trigger, the rotational torque or rotational speed, the rotational profile (profile), and the like by himself/herself.
e. Features described in the embodiments are for understanding the invention
The features described in the above embodiments can be understood as independent inventions. For example, from the viewpoint of the configuration, the axial direction of the motor 101, the rotation control of the motor 101, the axial direction of the gears constituting the speed reduction unit 102, the configuration of the housing unit 103, the relationship between the housing unit 103 and other components, and the like can be understood as independent inventions. From the functional point of view, the counter torque countermeasure, the noise, vibration, or abrasion countermeasure, the heat countermeasure, the compatibility countermeasure, the fun countermeasure, and the like can be understood as independent inventions.
(3) Operation of the air gun of the present embodiment
The operation of the air gun 1 of the present embodiment until the bullet is fired will be described.
When a trigger (not shown) is pulled by a user, a transmission instruction signal is transmitted to the control board 104. The control substrate 104 that receives the transmission instruction signal controls and rotates the motor 101.
The power of the motor 101 is transmitted to the piston 21 via the speed reducer 102.
Specifically, the toothed portion T of the drive gear 102d is engaged with the rack 24, and the piston 21 moves in the left direction in fig. 1.
The compression spring 23 is compressed by the movement of the piston 21.
On the other hand, the cartridge stored in the magazine 17 is loaded to the loading portion L located at the base of the barrel 11 by the negative pressure of the cylinder 22.
When the drive gear 102d further rotates so that the non-toothed portion N faces the rack 24, the restriction of the rack 24 is released, and the piston 21 receives the elastic force of the compression spring 23 and the piston 21 moves rightward in fig. 1.
By moving the piston 21 to the right, air is compressed in the cylinder 22 and pressure is generated to fire the bullet.
The bullet receives this pressure, moves while accelerating in the barrel 11, and is fired from the muzzle 11.
