Description

Technical Field

[0001] The invention relates to the technical field of air guns, in particular to a trigger mechanism and an air gun which are adjusted based on Hall magnetic induction triggering. Background Art

[0002] As is known to all, an airgun is a general term for a firearm that uses pressurized gas as a power source to fire a projectile. An airgun is a light weapon that does not use gunpowder for firing. Instead, it uses the pressure of compressed air or gas to fire the bullet. The trigger is a component of the firearm. When shooting, it is pulled by hand to fire the bullet. When the airgun needs to be fired, the trigger is squeezed, and the sear is released through mechanical transmission to allow the firing pin or hammer to fire the ammunition. The airgun adopts a pneumatic structure. The firing steps of the airgun are: (1) Compressing gas: compressing the gas in the external atmosphere and storing it in the cylinder to form high-pressure gas in the cylinder. One side of the compression valve is normal-pressure gas, and the other side of the compression valve is high-pressure gas. There is a gas transmission channel between the barrel and the cylinder; (2) Filling the projectile: When the gas is in the cylinder, the gas is compressed and stored in the cylinder. After the high-pressure gas is formed, the projectile is placed in the chamber, and the push rod is pulled, and the bullet moves to the firing position; (3) Trigger operation: while pulling the push rod backward, the hammer is forced to move backward through a mechanical connection and compress the spring energy storage. A spring cover is provided at the rear of the cylinder, which can block the outlet to prevent gas leakage. The spring and the moving hammer are combined into a trigger mechanism. When the projectile is loaded, the bolt is locked in place; (4) Launching the projectile: pulling the trigger immediately releases the high-pressure gas stored in the cylinder. The sudden expansion of the gas generates a high-pressure gas wave, which pushes the projectile toward the muzzle of the barrel. The sufficiently large driving force causes the projectile to be ejected from the barrel at high speed. This is the principle and steps of the air gun.

[0003] Hall magnetic induction is a magnetic induction technology based on the Hall effect. The main function of the Hall sensor is to identify the phase position information of the motor winding and convert it into an electrical value. The driver obtains the rotor position information by reading the electrical value at the output end of the Hall element, and then completes the correct commutation, passes current to the corresponding winding of the motor, forms an air gap rotating magnetic field, and keeps the motor running, ensuring the normal operation of the motor.

[0004] For example, the patent with the publication number CN103185482B and the publication date of April 15, 2015, entitled "Air Gun Trigger Mechanism", belongs to the field of air guns, and specifically relates to an air gun trigger mechanism, which is linked to a piston, and includes a firing bracket shell and a trigger, wherein a sear and a lever are connected in sequence in the firing bracket shell through a first pin and a second pin, wherein the upper edge of the front end of the sear corresponds to the piston, and the lower edge of the sear can abut against the upper edge of one end of the lever, and the other end of the lever is overlapped on the firing bracket shell, and the lower edge of the middle end of the lever can abut against the trigger hinged on the lever. The patent has a simple and compact structure, a long service life, and is time-saving and labor-saving to operate, and a synchronous safety when the air gun is loaded.

[0005] The shortcoming of the prior art is that the trigger mechanism of the airgun mostly adopts a mechanical structure (such as the cooperation between the sear, the firing bracket shell, the trigger and the lever) to fire, thereby releasing the gas stored in the cylinder, but the mechanical structure may cause the trigger to jam, thereby affecting the firing of the projectile.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig. 9 The present invention is further described in detail.

[0031] An embodiment provided by the present invention relates to a trigger mechanism that is adjusted based on Hall magnetic triggering, including a gearbox housing 1, a trigger unit is arranged in the gearbox housing 1, the trigger unit includes a trigger body 2 and an integrated circuit board 3, the integrated circuit board 3 is arranged in the gearbox housing 1, and a Hall sensor 4 is arranged on the integrated circuit board 3, the trigger body 2 is rotatably arranged on the gearbox housing 1, and a magnet 5 is arranged on the trigger body 2, and the switching of the trigger mechanism is realized by mutual induction between the magnet 5 and the Hall sensor 4.

[0032] Specifically, the trigger mechanism is the firing switch of the airgun, the gearbox housing 1 is the outer shell of the airgun, the integrated circuit board 3 is arranged on the gearbox housing 1, the integrated circuit board 3 is provided with a Hall sensor 4, and the trigger body 2 is provided with a magnet 5, the Hall sensor 4 and the magnet 5 are arranged relative to each other, and obviously, the Hall sensor 4 can detect the position of the magnet based on its own characteristics, so the Hall sensor 4 determines whether the trigger mechanism is fired or not by detecting the position of the magnet, and the Hall sensor 4 finally obtains the signal value, so it only needs to modify the corresponding preset value to determine that any rotation angle of the trigger mechanism is the firing angle, without the need for the trigger mechanism to be rotated to a fixed angle like a mechanical structure. Sensor detection and corresponding control are existing technologies and will not be described in detail.In a preferred embodiment, a program storage controller 6 is provided on the integrated circuit board 3, and the program storage controller 6 is electrically connected to a trigger trigger sensor 7, a mode conversion circuit 8, a photoelectric module 9, a motor drive 10, and a motor body 11, and the motor body 11 is electrically connected to a battery voltage regulator 12, and the battery voltage regulator 12 is electrically connected to the program storage controller 6; the program storage controller 6 is also electrically connected to a motor brake 13, and the motor brake 13 is electrically connected to the motor body 11, and the motor brake 13 is electrically connected to the battery voltage regulator 12, the trigger trigger sensor 7, the mode conversion circuit 8, the photoelectric module 9, the motor drive 10, the battery voltage regulator 12 and The motor brake 13 is arranged on the integrated circuit board 3, and the trigger body 2 is rotatably arranged on the gearbox housing 1. A reset torsion spring 14 is arranged between the trigger body 2 and the gearbox housing 1. When the air gun needs to be fired, the gunner presses the trigger body 2 to rotate it, and the synchronous trigger body 2 squeezes the reset torsion spring 14, so that the reset torsion spring 14 is in a compressed state, and the trigger body 2 drives the magnet 5 to rotate, and the magnet 5 and the Hall sensor 4 are mutually inductively sensed to realize the firing of the air gun by the trigger body 2, that is, the Hall sensor 4 senses the distance between the magnet 5 on the trigger body 2 and the Hall sensor 4 and the magnet 5 through the trigger trigger induction 7. 5 is converted into an electrical value (such as voltage or resistance, which is a common detection method of pressure sensors, converting pressure signals into electrical signals). If the electrical value detected by the photoelectric module 9 reaches the set value of the program storage controller 6, the firing instruction output is started, and the motor drive 10 is started through the photoelectric module 9, and the motor drive 10 starts the motor body 11. When the photoelectric module 9 detects the firing position, the program storage controller 6 issues an instruction to close the motor body 11, and the program storage controller 6 controls the motor brake 13 to start braking the motor body 11. Since the Hall sensor 4 can convert the distance position of the trigger body 2 into an electrical value, By modifying the settings of the mode conversion circuit 8 and the photoelectric module 9, the trigger can be arbitrarily set to trigger the firing of the air gun at any position within the stroke, thereby arbitrarily adjusting the sensitivity of the air gun firing and realizing adaptive adjustment of the sensitivity of the trigger body 2. Compared with the trigger mechanism that fires by a mechanical structure, the switch of the trigger body 2 is realized by circuit adaptation of the magnet 5 and the Hall sensor 4, and the trigger body 2 will not get stuck, thereby improving the stability of the air gun projectile firing, and by modifying the settings of the mode conversion circuit 8 and the photoelectric module 9, the trigger sensitivity of the trigger body 2 can be adjusted within the movement range of the trigger body 2.

[0033] The shortcoming of the prior art is that the trigger mechanism of the airgun mostly adopts a mechanical structure (such as the cooperation between the sear, the firing bracket shell, the trigger and the lever) to fire, thereby releasing the gas stored in the cylinder, but the mechanical structure may cause the trigger to jam, thereby affecting the firing of the projectile.

[0034] The beneficial effect of this embodiment is that when it is necessary to start the trigger mechanism of the air gun, the gunner presses the trigger body 2, the trigger body 2 drives the magnet 5 to rotate, the magnet 5 and the Hall sensor 4 on the integrated circuit board 3 are adapted to each other, so that the magnet 5 and the Hall sensor 4 cooperate with each other to realize the switching of the trigger. Compared with the trigger mechanism with a mechanical structure for firing, the switching of the trigger body 2 is realized by the circuit adaptation of the magnet 5 and the Hall sensor 4, and the trigger body 2 will not get stuck, thereby improving the stability of the air gun projectile firing.

[0035] Another embodiment of the present invention further provides an air gun, comprising a cylinder body 15, the gearbox housing 1 is provided with the above-mentioned trigger mechanism, the gearbox housing 1 is provided with the cylinder body 15, the cylinder body 15 is provided with a piston body 16 in a sliding seal, the side wall of the gearbox housing 1 is provided with a guide rod 17, the guide rod 17 is sleeved with a spring body 18, one end of the spring body 18 is connected to the side wall of the gearbox housing 1, and the other end of the spring body 18 is connected to the end of the piston body 16; the motor body 11 is provided in the gearbox housing 1, and the gearbox housing 1 is provided with a piston body 16. A motor gear 19 is dynamically provided, and the motor gear 19 and the output end of the motor body 11 are connected to each other in a transmission manner, such as abutting each other to achieve friction transmission. A transmission gear 20 is rotatably provided in the gearbox housing 1, and the transmission gear 20 and the motor gear 19 are meshed with each other. A piston gear 21 is rotatably provided in the gearbox housing 1, and the transmission gear 20 and the piston gear 21 are meshed with each other. A rack 22 is provided at the bottom end of the piston body 16, and the rack 22 and the piston gear 21 are meshed with each other. The meshing part of the piston gear 21 and the rack 22 is a half-face tooth.

[0036] Specifically, the trigger mechanism is a switch triggered by the air gun. When it is detected that the trigger mechanism is turned to a set position, such as when the electrical value detected by the photoelectric module 9 reaches the set value of the program storage controller 6 and the firing command is started, the motor drive 10 is started through the photoelectric module 9, and the motor drive 10 starts the motor body 11. Since the motor body 11 and the motor gear 19 are in friction transmission with each other, the motor body 11 drives the motor gear 19 to rotate, the motor gear 19 drives the transmission gear 20 to rotate, and the transmission gear 20 drives the piston gear 21 to rotate. Since the piston gear 21 is only provided with half-face teeth, the piston gear 21 drives the rack 22 moves, the rack 22 drives the piston body 16 to slide in the cylinder body 15, so that the piston body 16 compresses the gas in the external atmosphere and stores it in the cylinder body 15, and the piston body 16 forms high-pressure gas in the cylinder body 15. At the same time, the piston body 16 squeezes the spring body 18, so that the spring body 18 is in a compressed energy storage state. At this time, the piston gear 21 rotates to the end of the stroke that meshes with the rack 22. At this time, the gas forms high-pressure gas in the cylinder body 15. At this time, when the photoelectric module 9 detects the firing position, the program storage controller 6 issues an instruction to close the motor body 11, and the program storage controller 6 controls The motor brake 13 starts braking the motor body 11, and then the gunner places the projectile in the chamber, and the program storage controller 6 starts the motor drive 10, and the motor drive 10 starts the motor body 11, and the motor body 11 drives the piston gear 21 to rotate through the motor gear 19 and the transmission gear 20. Since the part of the piston gear 21 that meshes with the rack 22 is a half-face tooth, when the piston gear 21 continues to rotate, its half-face tooth and the rack 22 are disengaged from each other, so that the rack 22 loses the meshing position of the piston gear 21, and under the rebound action of the spring body 18, the spring body 18 drives the piston to slide in the cylinder body 15 , so that the high-pressure gas stored in the cylinder body 15 is immediately released, and the sudden expansion of the gas generates a high-pressure gas wave, which pushes the projectile to move toward the muzzle of the gun barrel. A sufficiently large driving force causes the projectile to be ejected from the gun barrel at high speed, thereby achieving the firing of the air gun. After the air gun is fired, the motor body 11 continues to drive the piston gear 21 to rotate through the motor gear 19 and the transmission gear 20 until the teeth of the piston gear 21 are in meshing position with the end teeth of the rack 22. At this time, the program storage controller 6 controls the motor brake 13 to start braking the motor body 11, thereby facilitating the next firing of the air gun.

[0037] In another embodiment provided by the present invention, an air nozzle 23 is provided at the air outlet end of the piston body 16, a raised round rod 24 is provided on the side wall of the piston gear 21, and a pull bridge 25 is slidably provided at the bottom end of the cylinder body 15 in the gearbox housing 1, one end of the pull bridge 25 is connected to the air nozzle 23, and the other end of the pull bridge 25 is a circular arc part 26, and the circular arc part 26 and the raised round rod 24 abut and cooperate with each other.

[0038] Specifically, when the motor body 11 continues to drive the piston gear 21 to rotate to the end of the stroke where it meshes with the rack 22 through the motor gear 19 and the transmission gear 20, the piston gear 21 drives the pull bridge 25 to slide toward the end away from the cylinder body 15 through the raised round rod 24. When the piston gear 21 rotates to the end of the stroke where it meshes with the rack 22, the pull bridge 25 drives the air nozzle 23 to slide to a position where it abuts against the piston body 16. At this time, the raised round rod 24 and the pull bridge 25 are separated from each other as the arc part 26. When the high-pressure gas stored in the cylinder body 15 is immediately released, the gas is ejected from the air nozzle 23. The high-pressure gas wave pushes the projectile to move toward the muzzle of the gun barrel. A sufficiently large driving force causes the projectile to be ejected from the gun barrel at high speed, thereby achieving the firing of the air gun.

[0039] In another embodiment provided by the present invention, a positioning shaft 27 is provided on the gearbox housing 1, a positioning groove 28 is provided on the positioning shaft 27, a sleeve 29 is slidably provided on the positioning shaft 27, a pin 30 is provided on the sleeve 29, the pin 30 is slidably provided in the positioning groove 28, a positioning rod 31 is provided on the positioning shaft 27, a piston gear 21 is rotatably provided on the sleeve 29, the piston gear 21 is slidably provided between the positioning rod 31, a sliding round rod 32 is provided on the side wall of the sleeve 29, and a piston gear 21 is rotatably provided on the side wall of the gearbox housing 1. An auxiliary round rod 33 is provided with a propulsion tube 34, and the propulsion tube 34 is connected to the trigger body 2, that is, the trigger body 2 is located at one end of the gearbox housing 1 and is provided with the propulsion tube 34, and a propulsion groove 35 is provided on the annular outer wall of the propulsion tube 34, and the middle part of the propulsion groove 35 is a beveled spiral groove 351, and the beveled spiral groove 351 is connected to a first arc surface groove 352 at one end close to the auxiliary round rod 33, and the beveled spiral groove 351 is connected to a second arc surface groove 353 at one end away from the auxiliary round rod 33, and the sliding round rod 32 is slidably provided in the propulsion groove 35.

[0040] Specifically, since the trigger mechanism of the airgun is composed of electronic components such as the trigger trigger sensor 7, the mode conversion circuit 8, the photoelectric module 9, the motor drive 10, the battery voltage regulator 12 and the motor brake 13 on the integrated circuit board 3, but the trigger mechanism has no insurance, there is a risk of accidental discharge, that is, the trigger body 2 is not pulled but the motor body 11 is started. In this embodiment, when the trigger body 2 is in a position where it has not been pressed, the piston gear 21 is located on the positioning shaft 27 and is not engaged with the rack 22, but is secured to the piston gear 21 by the positioning rod 31 on the positioning shaft 27. The piston gear 21 is prevented from rotating on the positioning shaft 27. A propulsion groove 35 is provided on the annular outer wall of the propulsion cylinder 34. The propulsion groove 35 is formed by connecting the first arc groove 352, the inclined spiral groove 351 and the second arc groove 353 in sequence. When the trigger body 2 is in a position where it has not been pressed, the sliding round rod 32 is slidably arranged in the first arc groove 352. When the gunman presses the trigger body 2, the trigger body 2 squeezes the reset torsion spring 14. The gunman keeps pressing the trigger body 2, so that the trigger body 2 is in a compressed energy storage state, and the trigger body 2 drives The propulsion cylinder 34 rotates around the auxiliary round rod 33. During the rotation of the propulsion cylinder 34, the sliding round rod 32 slides along the track of the propulsion groove 35. The sliding round rod 32 slides from the first arc surface groove 352 and the inclined spiral groove 351 to the second arc surface groove 353 until the trigger body 2 rotates to the end of its stroke. At this time, the sliding round rod 32 slides into the second arc surface groove 353, and the sliding round rod 32 drives the sleeve 29 to slide toward one end close to the rack 22. Since the sleeve 29 is provided with a pin rod 30, and the pin rod 30 is slidably arranged in the positioning groove 28, the sleeve 29 No rotation occurs when sliding on the positioning shaft 27. At the same time, the sleeve 29 drives the piston gear 21 to slide toward one end close to the rack 22. Since a positioning rod 31 is provided on the positioning shaft 27, the piston gear 21 does not rotate during movement. When the piston gear 21 just slides away from the positioning rod 31, the piston gear 21 is just fully meshed with the rack 22. The sliding round rod 32 and the second arc groove 353 prevent the piston gear 21 and the sleeve 29 from continuing to slide on the positioning shaft 27, thereby realizing the positioning of the piston gear 21 and the sleeve 29 on the positioning shaft 27.

[0041] When the piston gear 21 and the rack 22 are fully meshed with each other, the photoelectric module 9 detects the firing position and issues a command through the program storage controller 6 to start the motor body 11. The motor body 11 drives the motor gear 19 to rotate, the motor gear 19 drives the transmission gear 20 to rotate, and the transmission gear 20 drives the piston gear 21 to rotate. Since the piston gear 21 is only provided with half-face teeth, the piston gear 21 drives the rack 22 to move, and the rack 22 drives the piston body 16 to slide in the cylinder body 15, so that the piston body 16 compresses the gas in the external atmosphere and stores it in the cylinder body 15. The piston body 16 forms high-pressure gas in the cylinder body 15. At the same time, the piston body 16 squeezes the spring body 18, so that the spring body 18 is in a compressed energy storage state. At this time, the piston gear 21 rotates to the end of the stroke meshing with the rack 22. At this time, the gas forms high-pressure gas in the cylinder body 15. At this time, when the photoelectric module 9 detects the firing position, the program storage controller 6 issues a command to close the motor body 11, and the program storage controller 6 controls the motor brake 13 to start the motor body 11 is braked, and then the gunner places the projectile in the chamber, the program storage controller 6 starts the motor drive 10, the motor drive 10 starts the motor body 11, the motor body 11 drives the piston gear 21 to rotate through the motor gear 19 and the transmission gear 20, so that the teeth on the piston gear 21 and the rack 22 are disengaged from each other, so that the rack 22 loses the meshing position of the piston gear 21, and under the rebound effect of the spring body 18, the spring body 18 drives the piston to slide in the cylinder body 15, so that the high-pressure gas stored in the cylinder body 15 is immediately released. When the air gun is released, the sudden expansion of the gas generates a high-pressure gas wave, which pushes the projectile toward the muzzle of the gun barrel. The sufficiently large driving force causes the projectile to be ejected from the gun barrel at high speed, thereby achieving the firing of the air gun. When the air gun is fired, the motor body 11 continues to drive the piston gear 21 to rotate through the motor gear 19 and the transmission gear 20 until the teeth of the piston gear 21 and the end teeth of the rack 22 are meshed with each other (that is, the position where the positioning rod 31 and the piston gear 21 are positioned with each other). At this time, the shooter releases the pressure on the trigger body 2.

[0042] When the shooter releases the pressure on the trigger body 2, the reset torsion spring 14 pushes the trigger body 2 to rotate to the initial position (i.e., the position where the shooter does not press), and the trigger body 2 drives the propulsion tube 34 to rotate around the auxiliary round rod 33. During the rotation of the propulsion tube 34, the sliding round rod 32 slides along the trajectory of the propulsion groove 35, and the sliding round rod 32 slides from the second arc surface groove 353 and the inclined spiral groove 351 to the first arc surface groove 352 until the trigger body 2 rotates to the initial position. The sliding round rod 32 slides into the first arc groove 352, and the sliding round rod 32 drives the sleeve 29 to slide toward the end away from the rack 22. Since the sleeve 29 is provided with a pin rod 30, and the pin rod 30 is slidably set in the positioning groove 28, the sleeve 29 does not rotate when sliding on the positioning shaft 27. At the same time, the sleeve 29 drives the piston gear 21 to slide toward the end away from the rack 22. Since the positioning shaft 27 is provided with a positioning rod 31, the piston gear 21 does not rotate during movement, which provides convenience for the next firing of the air gun.

[0043] In this embodiment, the transmission between the piston gear 21 and the gear is achieved by the mutual disengagement and engagement of the piston gear 21 and the rack 22. When the piston gear 21 and the rack 22 are disengaged from each other, the air gun will not fire even if the integrated circuit board 3 is out of control, thereby improving the safety of the air gun.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
