Description

Technical Field

[0001] This invention belongs to the field of firearms technology, specifically relating to a controllable multi-functional firing mechanism. Background Technology

[0002] The firing mechanism is the mechanism in a firearm that controls the firing action. With the development of modern technology, the complexity and cross-cutting nature of warfare are becoming increasingly apparent, and various unmanned combat platforms are emerging. On existing small-caliber light weapon unmanned combat platforms, weapon units typically use conventional standard firearms and employ two servo-controlled mechanisms to control the weapon's trigger and safety, and a motor-controlled mechanism to complete the first-shot loading action. Three or more of these mechanisms inevitably affect the weapon's weight, mobility, and serviceability. In order to improve the overall combat performance of small-caliber unmanned light weapons, there is an urgent need to propose a controllable multi-functional firing mechanism controlled by a single servo motor (electric motor) that can control single-shot and burst fire (burst fire radio frequency controllable), safety, and first-shot loading (it can also be manually controlled to control burst fire, safety, and first-shot loading). Summary of the Invention

[0003] The purpose of this invention is to provide a controllable multi-functional firing mechanism for a special firearm, which can realize single-shot and burst fire (burst fire radio frequency controllable), safety, and first-shot loading controlled by a single servo motor, or manual control of burst fire, safety, and first-shot loading.

[0004] The technical solution to achieve the purpose of this invention is as follows:

[0005] A controllable multi-functional launching mechanism includes a launcher base, servo motors and control panel mechanisms respectively fixed on both sides of the launcher base, a firing mechanism, an out-of-position safety, a sear and a mechanical safety rotatably connected in the launcher base, and a trigger linkage and a trigger linkage spring disposed in the launcher base.

[0006] The out-of-position safety is located at the lower end of the firing mechanism. Under the action of the out-of-position safety sear spring, the front end contacts the firing mechanism to control the burst fire of the firearm and at the same time ensure that the firearm cannot be fired if the bolt has not returned to the correct position.

[0007] The hammer spring push rod is coaxially arranged with the firing mechanism, with its front end connected to the mechanical safety latch and its rear end in contact with the firing mechanism, and is used to limit the movement stroke of the firing mechanism.

[0008] The sear is located at the front end of the out-of-position safety mechanism. Under the action of the sear spring, the upper rear side contacts the firing mechanism to control the firing action of the firing mechanism. The front end contacts the control panel mechanism, serving as a mechanism for both electronic and manual safety.

[0009] The out-of-position safety stop spring is coaxial with the stop iron and is used to provide an upward rotational force to the front end of the out-of-position safety stop and a backward rotational force to the upper end of the stop iron.

[0010] The trigger linkage can, under the action of the trigger linkage spring, have its rear end in contact with the mechanical safety and its side end in contact with the sear, and can drive the sear to rotate under the drive of the control panel mechanism;

[0011] The control panel mechanism is equipped with manual and electronic safety, initial loading, and firing ports;

[0012] The output shaft of the servo motor engages with the bore of the control disc mechanism to drive the control disc mechanism to rotate. By controlling the rotation angle of the control disc mechanism, single-shot and burst fire can be achieved. The rotation of the control disc mechanism drives the bolt to move backward, and the bolt drives the firing mechanism to rotate. After the control disc mechanism rotates a certain angle, it separates from the bolt, and the bolt returns to its forward position to complete the first shot loading action.

[0013] The significant advantages of this invention compared to existing technologies are:

[0014] (1) The present invention uses a single servo motor to realize the control of single-point firing and burst firing (burst firing radio frequency controllable), safety, and first-shot loading of a special weapon, which can greatly reduce the overall weight and cost of the weapon;

[0015] (2) This invention uses a low-power bus servo motor, which can realize low-power weapon control;

[0016] (3) The present invention has both manual and electrical safety mechanisms, providing double protection for safety. The manual safety mechanism can prevent the special weapon from going out of control while in standby mode.

[0017] (4) This invention can be controlled by bus servo motors, and can realize the parallel connection and simultaneous control of multiple weapons and multiple servo motors. Attached Figure Description

The hammer shaft is located above and in front of the out-of-position safety shaft, and the sear shaft is located below and in front of the hammer shaft.

[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] In this embodiment, the terms "upper," "lower," "left," "right," "front," "rear," "upper end," and "lower end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0047] In this embodiment, along the front view Figure 7 The right-hand rule for outward normal vectors specifies the direction as counterclockwise.

[0048] In this embodiment, the servo is a servo that can control a maximum output angle of 360°. The specific internal structure of the servo, as well as the external control board and power supply, are omitted. Only the servo housing and output shaft are used for the description of the invention.

[0049] In this embodiment, the selected dedicated weapon frame must be equipped with or have a rack portion that can cooperate with the gear portion on the external control panel.

[0050] In this embodiment, manual control refers to using a component with the same shape at one end as the D-axis of the servo motor instead of a servo motor for manual control, without using a servo motor.

[0051] In this embodiment, the angles mentioned are all theoretical design angles and therefore should not be construed as limitations on the present invention.

[0052] In this embodiment, the hammer, hammer spring, hammer spring guide rod, and hammer spring top rod together constitute the firing mechanism, which is consistent with the firing mechanism of existing firearms in terms of structural principle, only with different design dimensions.

[0053] Combination Figure 1-26 This embodiment of a controllable multi-functional launching mechanism includes a launcher base 1, a control panel mechanism 2, a servo cover 3, an out-of-position safety shaft 4, an out-of-position safety 5, a hammer shaft 6, a hammer bushing 7, a sear shaft 8, a sear bushing 9, an out-of-position safety sear spring 10, a servo motor 11, a sear 12, a trigger linkage 13, a mechanical safety 14, a hammer 15, a hammer spring 16, a hammer spring guide rod 17, a hammer spring push rod 18, a trigger linkage spring 19, a control panel mechanism fixing pin 20, a servo cover fixing bolt 21, and a safety release lever 22. The launcher base 1 serves as the base of the controllable multi-functional launching mechanism, and has four shaft holes 101 and mounting holes for each component. It has an internal launcher base surface 102. Each component is mounted on the launcher base 1 in a specific manner, as described below. The hammer 15, hammer spring 16, hammer spring guide rod 17, and hammer spring push rod 18 together constitute the firing mechanism.

[0054] Combination Figure 1-7 The out-of-position safety shaft 4, hammer shaft 6, sear shaft 8, and mechanical safety 14 are respectively inserted into the four shaft holes 101 of the transmitter base 1, and can rotate within their respective shaft holes 101. The specific structure of the mechanical safety 14 is as follows: Figure 22 As shown, the mechanical safety 14 is provided with a limiting surface 1401, a mechanical safety unlocking surface 1402, a mechanical safety surface 1403, a clearance surface 1404, and a groove surface 1405. The limiting surface 1401 and the clearance surface 1404 are the inner planes of the mechanical safety 14. The mechanical safety unlocking surface 1402 is located at the side end of the mechanical safety 14. The mechanical safety surface 1403 is the outer circular surface of the mechanical safety 14. The groove surface 1405 is a W-shaped groove surface located in the middle of the mechanical safety 14. A non-positioning safety 5 that can rotate around the non-positioning safety shaft 4 is fitted on it. The specific structure of the non-positioning safety 5 is as follows. Figure 23 As shown, the front part curves upward, and under the action of the out-of-position safety spring 10, the curved part contacts the hammer 15. The out-of-position safety 5 is initially pressed down by the frame, and the middle part has a first mating surface 501 that can cooperate with the hammer 15. The hammer shaft 6 is located above the front side of the out-of-position safety shaft 4, and a hammer shaft sleeve 7 that can rotate around it is fitted. The hammer 15 and the hammer spring push rod 18 that can rotate around it are fitted on the hammer shaft sleeve 7. The specific structure of the hammer 15 is as follows. Figure 24As shown, the lower end of the hammer 15 has a second mating surface 1501 and a third mating surface 1502 that can mate with the sear 12 and the misalignment safety 5. The hammer spring push rod 18 is installed inside the hammer 15. The hammer 15 contains a hammer spring 16. The upper end of the hammer spring 16 contacts the upper inner surface of the hammer 16, and the lower end contacts the hammer spring guide rod 17. The rear end of the hammer spring push rod 18 contacts the lower end of the hammer spring guide rod 17. The front end protrusion of the hammer spring push rod 18 mates with the groove surface 1405 at the lower end of the mechanical safety 14, restricting its rotation. The sear shaft 8 is located in front of the misalignment safety shaft 4 and is fitted with a sear bushing 9 that can rotate around it. A sear 12 that can rotate around it is fitted on the sear bushing 9. The specific structure of the sear 12 is as follows. Figure 25 As shown, the sear 12 has a first sear surface 1201, a second sear surface 1202, and a fourth mating surface 1203. The two first sear surfaces 1201 are located at the upper end of the sear 12, and the fourth mating surface 1203 is located at the rear end of the first sear surface 1201. The second sear surface 1202 is located at the front end of the sear 12. The out-of-position safety sear spring 10 is fitted onto the sear bushing 9, and its rear end contacts the upper middle part of the out-of-position safety 5, giving it a force to rotate counterclockwise around the out-of-position safety shaft 4 (causing the front end of the out-of-position safety 5 to rotate backward). The front end of the out-of-position safety sear spring 10 contacts the front part of the upper end of the sear 12, giving it a force to rotate counterclockwise around the sear shaft 8. The rear part of the upper end of the sear 12 is pressed by the out-of-position safety sear spring 10 against the lower front end of the hammer 15. The trigger linkage 13 is installed inside the transmitter base 1, as shown in the figure. The specific structure of the trigger linkage 13 is as follows: Figure 26 As shown, a trigger linkage surface 1301 is provided on the left side of the front end, which contacts the trigger linkage spring 19 at the front end, and an arc-shaped rod is provided at the rear end, which contacts the limiting surface 1401 of the mechanical safety 14.

[0055] Combination Figure 8-10 The control panel mechanism 2 is fixed to the left end of the transmitter base 1 by the control panel mechanism fixing pin 20; the servo motor 11 is fixed to the right end of the transmitter base 1 by the servo motor cover 3 and the servo motor cover fixing bolt 21; combined with Figure 10 The control panel mechanism 2 and the servo motor 11 transmit force through the D-shaped hole 20105 and the D-shaped shaft 1101.

[0056] Combination Figure 11-14 The control panel mechanism 2 includes an inner control panel 201, an inner pawl 202, an inner pawl spring 203, an outer control panel 204, an outer pawl 205, an outer pawl spring 206, and a control panel cover 207. Combined with... Figure 11The inner control disk 201, inner pawl 202, inner pawl spring 203, outer control disk 204, outer pawl 205, and outer pawl spring 206 are installed in the control disk cover 207 in sequence from the outside to the inside. The D-shaped hole 20105 is located in the center of the inner control disk 201. The left end face of the inner control disk 201 is provided with a first ratchet surface 20104, which is installed inside the right end of the outer control disk 204. The three inner pawls 202 and the three inner pawl springs 203 are respectively fitted onto the outer control disk 204. On the right end face of the control panel 204, three internal shafts 20403 are arranged at equal intervals along the circumference of the outer control panel 204. Each internal pawl 202 is engaged with an internal pawl spring 203. The two sides of the internal pawl 202 are in contact with the inner control panel 201 and the outer control panel 204. The internal pawl spring 203 presses the inner pawl surface 20201 of the internal pawl 202 against the first ratchet surface 20104, so that the first ratchet surface 20104 can be controlled by the outer control panel. The right side of the outer control disk 204 rotates unidirectionally (clockwise); the right side of the outer control disk 204 has an incomplete toothed surface 20402 along the circumferential direction of its outer surface, and the left end face has a second ratchet surface 20401. This second ratchet surface 20401 is installed inside the right end of the control disk cover 207. Three external pawls 205 and three external pawl springs 206 are fitted onto three internal shafts 20401 provided on the right end face of the control disk cover 207. The three internal shafts 20401 are... The control panel cover 207 is arranged at equal intervals in the circumferential direction. Each external pawl 205 is used in conjunction with an external pawl spring 206. The two sides of the external pawl 205 are in contact with the external control panel 204 and the control panel cover 207. The external pawl spring 206 presses the external pawl surface 20501 of the external pawl 205 against the second ratchet surface 20401 of the external control panel 204, so that the second ratchet surface 20401 can rotate unidirectionally inside the right end of the control panel cover 207 (the rotation direction is counterclockwise).

[0057] Combination Figure 14 The inner control panel 201 is provided with an inner control panel protrusion 2010106 and mounting holes for an electric trigger 20101 and an electric trigger spring 20103. When the launching mechanism moves, the electric trigger 20101 has a first electric trigger surface 2010101 on its upper part that can contact the launcher base surface 102 under certain movement conditions, and a second electric trigger surface 2010101 that can contact the trigger linkage surface 1301 under certain movement conditions when the launching mechanism moves. The trigger face 2010102 and the inner control panel 201 have an electric trigger limit pin 20102 installed in the mounting hole. The electric trigger limit pin 20102 limits the upward and downward sliding position of the electric trigger 20101 in the mounting hole. The electric trigger spring 20103 is located between the electric trigger 20101 and the inner control panel 201. The inner control panel 201 has a D-shaped hole 20105 at its center, which mates with the servo motor D-shaped shaft 1101.

[0058] Combination Figure 15 After the safety lever 22 is inserted into the mechanical safety 14, the mechanical safety 14 can be rotated by the cooperation between the unlocking surface 2201 of the safety lever and the unlocking surface 1402 of the mechanical safety 14. The unlocking surface 2201 of the safety lever and the unlocking surface 1402 of the mechanical safety are shown in the figure as a nonagon, and any shape that can transmit force to satisfy the cooperation relationship is also acceptable.

[0059] The operation process of the controllable multifunctional launching mechanism described in this invention is as follows:

[0060] Combination Figure 12-14 16-19 Explanation of the initial loading stage: The servo D-axis 1101 drives the inner control disk 201 to rotate counterclockwise. The first ratchet surface 20104 of the inner control disk 201 engages with the inner pawl surface 20201, driving the outer control disk 204 to rotate counterclockwise. The second ratchet surface 20401 of the outer control disk 204 engages with the outer pawl surface 20501, causing the outer pawl 205 to be lifted and the outer pawl spring 206 to be compressed. When the outer control disk 204 rotates counterclockwise by a certain angle, the incomplete tooth surface 20402 of the outer control disk engages with the tooth surface on the frame. When tooth surface 23 contacts, it drives the machine frame to move backward, pressing down on hammer 15 and causing it to rotate counterclockwise. Hammer 15 presses down on the out-of-position safety 5. After hammer 15 rotates a certain angle, the out-of-position safety 5 is rebounded by the out-of-position safety stop spring 10. The third mating surface 1502 on the rear side of the lower end of hammer 15 engages with the first mating surface 501 of the out-of-position safety surface 5. When the outer control panel 204 continues to rotate counterclockwise until the incomplete tooth surface 20402 no longer contacts tooth surface 23 on the machine frame, the machine frame is driven by its own recoil spring to recoil and complete the first loading. Figure 7 , Figure 17 , Figure 18 Simultaneously, when the internal control panel 201 rotates counterclockwise by a certain angle, the first trigger surface 2010101 contacts the upper transmitter base surface 102, engaging... Figure 14 , 18 At this point, the electric trigger 20101 compresses the electric trigger spring 20103, retracting into the inner control panel 201. It continues to rotate a certain angle until the first electric trigger face 2010101 no longer contacts the transmitter base face 101, at which point the electric trigger 20101 is ejected. The initial loading action is completed when the inner control panel 201 drives the outer control panel 204 to rotate counterclockwise one full turn. At this time, the second mating surface 1501 on the lower front side of the hammer 15 engages with the fourth mating surface 1203 of the sear 12 (when the frame retracts into position, the frame presses down the non-alignment safety 5, causing the third mating surface 1502 of the hammer 15 to disengage from the first mating surface 501 of the non-alignment safety surface 5). If manual control is used, the servo motor 11 is removed. For manual initial loading, a component with one end shaped like the servo motor's D-shaped shaft 1101 is inserted into the D-shaped hole 20105 of the inner control panel 201 and rotated counterclockwise one full turn to complete the initial loading.

[0061] Combination Figure 7 , 12 -15, 19, and 20 illustrate the dual-safety phase: In the non-combat state of the dedicated weapon, the mechanical safety face 1403 is in contact with the first sear face 1201, preventing the sear 12 from rotating and locking the transmitter. The safety lever 22 must be inserted into the mechanical safety 14. The safety lever's unlocking face 2201, in conjunction with the mechanical safety unlocking face 1402, rotates the mechanical safety 14 by a certain angle, causing the mechanical safety face 1403 to no longer contact the first sear face 1201. At this point, the sear 12 can rotate, and the weapon is in an electronically controlled, fireable state. After the first shot is loaded, combined with... Figure 19 The inner control disk protrusion 2010106 engages with the second sear surface 1202, restricting the sear 12 from rotating clockwise, thus preventing the weapon from firing. When the servo motor D-axis 1101 drives the inner control disk 201 to rotate clockwise, the first ratchet surface 20104 of the inner control disk 201 engages with the inner pawl surface 20201, causing the inner pawl 202 to be lifted and the inner pawl spring 203 to be compressed. The second ratchet surface 20401 of the outer control disk 204 engages with the outer pawl surface 20501, preventing rotation. When rotated by a small angle of 10°, the inner control disk surface 2010106 and the second sear surface 1202 are misaligned, allowing the sear 12 to rotate clockwise, and the weapon is in a ready-to-fire state. Figure 8 , 20 At this point, the second electric trigger face 2010102 is in contact with the trigger linkage face 1301. If manual control is used, the servo 11 is removed. After the mechanical safety 14 is opened, the weapon is in a manually fireable state. When a component with one end shaped like the servo D-type shaft 1101 is inserted into the D-type hole 20105 of the inner control disc 201 and rotated clockwise by less than 10°, the second electric trigger face 2010102 is not in contact with the trigger linkage face 1301, and the weapon cannot be fired; this is the trigger safety stage.

[0062] Combination Figure 7 , 20 21. Explanation of the firing phase: After the weapon is in the ready-to-fire state, the second electric trigger surface 2010102 contacts the trigger linkage surface 1301. When the servo motor D-axis 1101 drives the inner control disk 201 to continue rotating clockwise by a small angle of 5°, the combination... Figure 21The lower rear end of the trigger linkage 13 drives the upper front end of the sear 12 to rotate clockwise, causing the second mating surface 1501 of the hammer 15 to disengage from the fourth mating surface 1203 of the sear 12, thus releasing the hammer 15. Controlling the servo 11 to rotate 5° and immediately return allows for single-shot firing; controlling the servo 11 to rotate 5° without returning allows for continuous firing; controlling the servo 11 to rotate 5° multiple times within a certain time period allows for burst fire and radio frequency controllable continuous firing. If using manual control, remove the servo 11. After the first shot is loaded, insert a component with the same shape at one end as the servo's D-shaped shaft 1101 into the D-shaped hole 20105 of the inner control disc 201 and rotate it clockwise by 15° to release the hammer 15 (the first 10° is the trigger safety phase, and the last 5° is the hammer release phase), allowing for continuous weapon firing.
