Description

Technical Field

[0001] This invention relates to the field of firearms technology, specifically to a fire selector mechanism and a firearm. Background Technology

[0002] To achieve reliable firing mode switching, a mechanical fire selector mechanism is currently widely used. Its core is to intervene in the trigger reset logic by changing the state of a certain moving part, thereby realizing the conversion between single-shot mode and burst-fire mode.

[0003] In some applications, the mode selection function is directly integrated into the upper components involved in the bolt's reciprocating motion. For example, the fire selector button is located on the push rod or related actuator that moves with the bolt carrier. By toggling this button, the user can directly change the position of the linkage, thereby determining whether it interferes with the trigger linkage during the bolt's movement cycle, thus controlling the firing mode.

[0004] However, because the selection button must reciprocate along with the high-speed moving bolt components, its position changes dynamically and it is difficult to touch stably. Furthermore, there is a safety risk of damage to the mechanism or accidental mode switching due to accidental contact during firing. At the same time, the exposed and moving button is very easy to snag on clothing, equipment or other items during carrying or use, affecting the safety and convenience of operation.

[0005] Therefore, this application studies a fast / slow machine structure to improve the safety and ease of operation during the interaction process. Utility Model Content

[0006] To improve security and ease of use during the interaction process.

[0007] On the one hand, the fast / slow speed mechanism structure provided in this application adopts the following technical solution: A speed control structure includes a base, a transmission assembly, an actuator, a trigger linkage, and a trigger. The transmission assembly includes a selection arm, a selection button, and a connecting member. The base has a cavity. The selection arm is rotatably mounted along the base, with its first end movable within the cavity. The selection button slides in a preset direction to select a mode. One end of the connecting member is connected to the selection button, and the other end is connected to the second end of the selection arm. Movement of the selection button drives the selection arm to swing via the connecting member. The swinging of the selection arm drives the actuator to a first position or a second position. When the actuator is in the first position, it is located on the movement path of the trigger link after being driven by the trigger. During the firing cycle, it is pushed and interferes with the reset of the trigger link, realizing the single-fire mode. When the actuator is in the second position, it is disengaged from the movement path of the trigger link, realizing the burst-fire mode.

[0008] By adopting the above technical solution, the selection button is separated from the actuator involved in the bolt movement, and the selection button is linked to the actuator through a transmission mechanism composed of a connector and a selection swing arm. This decouples the speed selector function from the high-speed moving parts, fundamentally solving the safety risks of the button being difficult to touch, inconvenient to operate, and prone to accidental touch during movement due to the movement of the bolt. Furthermore, it can be installed inside the firearm without being exposed, significantly improving the safety and ease of operation of human-machine interaction.

[0009] Optionally, the selection button has a positioning groove, and the end of the connector extends into the positioning groove. When the selection button is slid, the groove wall of the positioning groove abuts against the connector, causing the connector to drive the selection arm to rotate.

[0010] By adopting the above technical solution, a simple and reliable mechanical transmission method is provided through the cooperation between the positioning groove and the end of the connector, which accurately converts the linear sliding of the selection button into the movement of the connector, thereby driving the selection arm.

[0011] Optionally, the selection button is provided with a guide slope facing the positioning groove.

[0012] By adopting the above technical solution, in the event of accidental touch or displacement of the selection button, the connecting part can slide along the guide slope and automatically fall into the positioning groove, realizing the self-correction function of the gear position. Even if the operation is not in place, the mechanism can automatically return to the correct gear position, which greatly improves the fault tolerance and reliability of the operation and avoids the problem of misalignment caused by ambiguous operation.

[0013] Optionally, it also includes a mounting base, and the selector arm is provided with a gear positioning component. The gear positioning component includes a gear component and an elastic element sleeved on the gear component. The mounting base has at least two gear slots. When the selector arm rotates to the first position or the second position corresponding to the actuator, the gear component is engaged in the corresponding gear slot.

[0014] By adopting the above technical solution, the positioning component ensures that the actuator can stably and accurately stay at the single-shot or burst-fire position, improving the reliability and operation feel of mode switching and avoiding mode failure caused by unclear positioning.

[0015] Optionally, a reset element may also be included, which applies a biasing force to the actuator or the selection arm.

[0016] By adopting the above technical solution, the transmission mechanism can maintain a stable state and assist the components in returning to the correct position when subjected to slight disturbances.

[0017] Optionally, the actuator has a push rod portion and a push portion connected to each other, and the selection arm abuts against the push portion; when the actuator is in the first position, the push rod portion is located on the movement path of the trigger linkage after being driven by the trigger, and is pushed and interferes with the reset of the trigger linkage in the firing cycle to realize the single-fire mode; when the actuator is in the second position, the push rod portion disengages from the movement path of the trigger linkage to realize the burst-fire mode.

[0018] Optionally, the selection arm is provided with a positioning pin, and the base is provided with an arc-shaped groove. The positioning pin is inserted into the arc-shaped groove, and when the selection arm rotates, the positioning pin moves along the arc-shaped groove.

[0019] By adopting the above technical solution, precise trajectory guidance and limit are provided for the rotation of the swing arm, the range of motion of the swing arm is constrained, excessive swinging or misalignment is prevented, and the accuracy of the position switching of the actuator is ensured.

[0020] Optionally, an anti-accidental touch baffle is also included, which is disposed around the selection button.

[0021] By adopting the above technical solutions, it is possible to effectively prevent accidental mode switching caused by clothing, equipment or fingers touching the selection button during carrying, gripping or tactical actions, thereby further improving the safety and reliability of firearm use.

[0022] On the other hand, the firearm provided in this application adopts the following technical solution: A firearm includes the aforementioned fire selector structure and a housing. The fire selector structure is disposed within the housing. The housing has a sliding groove extending through it along its width. The selection button slides within the sliding groove and extends out of the sliding groove at both ends.

[0023] In summary, this application includes the following beneficial technical effects: 1. By separating the selection button from the actuator involved in the bolt movement, and linking the selection button with the actuator through a transmission mechanism composed of a connector and a selection swing arm, the speed selector function is decoupled from the high-speed moving parts. This fundamentally solves the safety risks of the button being difficult to touch, inconvenient to operate, and prone to accidental touch during movement, as it moves with the bolt. Furthermore, it can be installed inside the firearm without being exposed, significantly improving the safety and ease of operation of human-machine interaction. 2. The positioning component ensures that the actuator can stay stably and accurately at the single-shot or burst-fire position, improving the reliability and operation feel of mode switching and avoiding mode failure due to unclear positioning; 3. The guide slope allows the end of the connector to slide along the guide slope and automatically fall into the positioning groove with the cooperation of the reset component when the selection button is not fully pushed to the position. This achieves the self-correction function of the gear position. Even if the operation is not in place, the mechanism can automatically return to the correct gear position, which greatly improves the fault tolerance and reliability of the operation and avoids the problem of misalignment caused by ambiguous operation.

[0027] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0028] This application discloses a fast / slow speed mechanism structure. (Refer to...) Figure 1 The selector mechanism includes a base 1, a transmission assembly 2, an actuator 3, a trigger linkage 4, and a trigger 5. The transmission assembly 2 includes a selection arm 21, a selection button 22, and a connector 23. The base 1 has a cavity 6. The selection arm 21 is rotatably mounted along the base 1, with its first end located within the cavity 6. The selection arm 21 is rotatably connected to the base 1 via a rotating shaft 7, and one end of the rotating shaft 7 is rotatably connected to the gun mounting base 10. The mounting base 10 is fixed inside the gun housing. (The mounting base 10 can be referenced...) Figure 3 The selection button 22 can be slid along a preset direction to select a mode. The gun housing 20 has a sliding groove 8 extending through it along its width. The selection button 22 is a cuboid structure. The selection button 22 slides within the sliding groove 8 and extends out of the sliding groove 8 at both ends. By pushing the two sides of the selection button 22, the single-shot or burst-fire mode can be selected.

[0029] One end of the connector 23 is connected to the selection button 22, and the other end is connected to the second end of the selection arm 21. The movement of the selection button 22 drives the selection arm 21 to swing along the rotation axis 7 via the connector 23. The swing of the selection arm 21 drives the actuator 3 to be in the first position or the second position. Specifically, when the selection arm 21 swings laterally, the first end of the selection arm 21 can drive the actuator 3 to move and change its position in the lateral direction. When the actuator 3 is in the first position, the actuator 3 is located on the movement path of the trigger linkage 4 after being driven by the trigger 5. In the firing cycle, it is pushed and interferes with the reset of the trigger linkage 4, realizing the single-fire mode. When the actuator 3 is in the second position, the actuator 3 is disengaged from the movement path of the trigger linkage 4, realizing the burst-fire mode.

[0030] By separating the selection button 22 from the actuator 3 that participates in the bolt movement, and linking the selection button 22 with the actuator 3 through the transmission mechanism composed of the connector 23 and the selection swing arm 21, the speed selector function is decoupled from the high-speed moving parts. This fundamentally solves the safety risks of the button being difficult to touch, inconvenient to operate, and prone to accidental touch during movement, as it moves with the bolt. Furthermore, it can be installed inside the firearm without being exposed, significantly improving the safety and ease of operation of human-machine interaction.

[0031] Reference Figure 2 In some embodiments, the selection button 22 has a positioning groove 9, and the end of the connector 23 extends into the positioning groove 9. When the selection button 22 is slidable, it moves along the width of the gun, and the groove wall of the positioning groove 9 abuts against the connector 23, causing the connector 23 to drive the selection arm 21 to rotate. This makes it easy to convert the movement of the selection button 22 into the rotation of the selection arm 21.

[0032] In some embodiments, the selection button 22 is provided with a guide slope 15 facing the positioning groove 9. The guide slope 15 extends obliquely to the wall of the positioning groove 9, so that the connector 23 can slide along the guide slope 15 and automatically fall into the positioning groove 9 in the event of accidental touch or displacement of the selection button 22. This achieves a self-correction function for the gear position, and even if the operation is not in place, the mechanism can automatically return to the correct gear position, greatly improving the fault tolerance and reliability of the operation and avoiding the problem of misalignment caused by ambiguous operation.

[0033] Reference Figure 3 In some embodiments, a mounting base 10 is also included. A gear positioning assembly is provided on the selector arm 21. The gear positioning assembly includes a gear member 11 and an elastic member 12 sleeved on the gear member 11. The selector arm 21 has a receiving groove, and the elastic member 12, being a telescopic spring, is located within the receiving groove. The end of the gear member 11 has a hemispherical structure. The mounting base 10 has at least two gear slots 13, each hemispherically shaped and adapted to the shape of the gear member 11. When the selector arm 21 rotates to the first or second position corresponding to the actuator 3, the gear member 11 engages in the corresponding gear slot 13. During rotation, the elastic member 12 is compressed along the groove of the gear slot 13. When aligned with one of the gear slots 13, it engages in the corresponding gear slot 13, thereby placing the actuator 3 in the corresponding first or second position. This ensures more accurate positioning of the actuator 3, further preventing misalignment, and simultaneously limiting and positioning the position of the selector arm 21.

[0034] Refer again Figure 2 In some embodiments, a reset member 14 is also included, which applies a biasing force to the actuator 3 or the selection arm 21. The reset member 14 is a reset spring. When the reset spring applies a biasing force to the actuator 3, the actuator 3 positions the selection arm 21 accurately, aligning the gear position member 11 with the corresponding gear position groove 13, thereby further avoiding problems of incomplete or misaligned positioning. In this embodiment, the actuator 3 has a reset groove 16, and the reset member 14 is disposed in the reset groove 16, with one end abutting against the mounting base 10.

[0035] Reference Figure 2 With reference Figure 4In some embodiments, the actuator 3 has a push rod portion 31 and a push portion 32 connected to each other. The push rod portion 31 and the push portion 32 are arranged perpendicularly, and the push rod portion 31 has an inclined surface. The first end of the selector arm 21 abuts against the push portion 32. When the actuator 3 is in the first position, the push rod portion 31 is located on the movement path of the trigger linkage 4 after it is driven by the trigger 5. It is pushed in the firing cycle and interferes with the reset of the trigger linkage 4, realizing the single-fire mode. When the actuator 3 is in the second position, the push rod portion 31 is disengaged from the movement path of the trigger linkage 4, realizing the burst-fire mode. In this embodiment, the reset member 14 is specifically disposed inside the push portion 32.

[0036] Reference Figure 5 In some embodiments, a positioning pin 17 is provided on the selection arm 21, and an arc-shaped groove 18 is provided on the base 1. The positioning pin 17 is inserted into the arc-shaped groove 18. When the selection arm 21 rotates, the positioning pin 17 moves along the arc-shaped groove 18. By moving the positioning pin 17 along the arc-shaped groove 18, the rotation path of the selection arm 21 is guided and limited.

[0037] In some embodiments, an anti-accidental touch baffle 19 is also included, which is disposed around the selection button 22. The anti-accidental touch baffle 19 is integrally formed into the housing of the gun and covers the upper and both sides of the selection button 22, which can minimize accidental touch of the selection button 22, and also allows the operator to easily press the selection button 22 from below.

[0038] The implementation principle of the fire selector structure in this application embodiment is as follows: by separating the selection button 22 from the actuator 3 that participates in the bolt movement, and linking the selection button 22 with the actuator 3 through the transmission mechanism composed of the connector 23 and the selection swing arm 21, the fire selector selection function is decoupled from the high-speed moving parts. This fundamentally solves the safety risks of the button being difficult to touch, inconvenient to operate, and easy to accidentally touch during movement due to the movement of the bolt. Furthermore, it can be set inside the gun and not exposed, which significantly improves the safety and ease of operation of human-computer interaction.

[0039] This application also discloses a firearm. (See attached embodiments.) Figure 7 A firearm includes the aforementioned fire selector structure and housing 20. The fire selector structure is disposed inside the housing 20. The housing 20 has a sliding groove 8 extending through it in the width direction. The selection button 22 slides along the sliding groove 8 and extends out of the sliding groove 8 on both sides.
