Description

Technical Field

[0001] This utility model relates to the field of aiming technology, specifically to a toggle-press component, a button device, and a laser aiming device that prevents accidental touches. Background Technology

[0002] Laser sights are auxiliary devices used on firearms. Laser sights usually require a button device at the rear to achieve multi-functional operation. Traditional buttons often adopt a separate structure of toggle switch and push switch, which is controlled by a single toggle or push action.

[0003] However, existing tail button devices require multiple operations for function switching and triggering, which cannot meet the rapid response requirements of emergency missions. Moreover, when performing missions, the gun is usually worn on the user's waist, and the button device is easily hit by external force during the user's running, causing accidental activation. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a toggle and press component that prevents accidental touches. When used in a dark environment, the operator can operate blindly, thereby enabling quick switching and reliable triggering between different function levels. Moreover, when switching to different function levels, the swing arm needs to be toggled or pressed to trigger the switch of the different function level, which can avoid accidental triggering of the switch of different function levels due to external impact.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An anti-accidental-touch toggle and press assembly includes a swing arm and a locking plate. The swing arm and the locking plate are rotatably connected. The side of the swing arm near the locking plate is provided with a follower post and a protrusion. The locking plate is provided with a locking spring. The edge of the locking spring is provided with several arc grooves, which are smoothly transitioned to each other. The arc grooves are used to lock the follower post, and the locking spring has a deformation space in the direction away from the follower post. The locking plate is provided with a clearance position, and the locking spring is located in the clearance position. The clearance position is used to avoid the protrusion. The swing arm is elastic. When the swing arm is toggled, the swing arm swings around the rotation center. The swing arm drives the follower post to slide from one of the arc grooves along the edge of the locking spring until it is locked into another arc groove. When one end of the swing arm is pressed, the swing arm undergoes elastic deformation, and the swing arm drives the protrusion to move to one side of the locking plate.

[0007] As a further improvement to the above technical solution, the card plate is also provided with a number of pressing springs, each pressing spring having a pressing post. The pressing springs are located in the clearance position, and the pressing posts are arranged in an arc with the rotation center of the swing arm as the center. When one end of the swing arm is pressed, the protrusion presses down on the pressing spring, causing the pressing spring to undergo elastic deformation.

[0008] As a further improvement to the above technical solution, the number of arc grooves on the locking spring is three, the number of pressing springs and pressing posts is the same as the number of arc grooves, the height of the middle pressing post is lower than the height of the other two pressing posts, the protrusion is a hemispherical structure, and the top of the pressing post is a hemispherical structure.

[0009] As a further improvement to the above technical solution, the first and last ends of the locking spring are connected to the locking plate to form a closed structure. The edge of the locking spring has continuous undulating peaks and valleys, and the arc groove is located in the valley.

[0010] As a further improvement to the above technical solution, the locking plate is also provided with a lever arm, which is located within the closed structure of the locking spring piece. The lever arm is clearance-fitted with the inner surface of the locking spring piece to limit the maximum deformation displacement of the locking spring piece.

[0011] As a further improvement to the above technical solution, the rotation center of the swing arm is coaxially arranged with the geometric center of the positioning plate, the number of the follower column and the number of the protrusion are both two, the two follower columns and the two protrusions are symmetrically arranged along the rotation center of the swing arm, the number of the positioning spring is two, and the two positioning springs are symmetrically arranged along the center of the positioning plate.

[0012] As a further improvement to the above technical solution, both ends of the swing arm can be detachably connected to operation keys, which are used by the operator to toggle and press.

[0013] A button device includes a tail cover housing, a PCB assembly, and the aforementioned anti-accidental touch toggle pressing assembly. A rotating shaft is disposed within the tail cover housing, and the middle portion of a swing arm is rotatably connected to the rotating shaft. The tail cover housing has two clearance holes to prevent the two ends of the swing arm from protruding. A locking plate is fixedly connected to the tail cover housing. One end of the rotating shaft is connected to one side of the locking plate. The PCB assembly is located on the side of the locking plate away from the swing arm. The PCB assembly includes a plurality of microswitches, each microswitch corresponding to one of the pressing posts.

[0014] As a further improvement to the above technical solution, a washer is provided between the swing arm and the inner wall of the tail cover housing, and the washer is sleeved on the outer circumference of the rotating shaft.

[0015] As a further improvement to the above technical solution, a silicone pad is provided between the card slot plate and the PCB assembly, and a first accommodating cavity and a second accommodating cavity are provided on the tail cover housing. The first accommodating cavity is used to accommodate the card slot plate, and the second accommodating cavity is used to accommodate the silicone pad.

[0016] A laser sight includes a sight body and the aforementioned button device, wherein the button device is disposed at the rear of the sight body.

[0017] The beneficial effects of this utility model are as follows: This utility model provides a toggle-press assembly, a button device, and a laser sight to prevent accidental touches. By setting a swing arm and a locking plate, in the initial state, the follower column in the swing arm is locked in the arc groove at the middle position. By pressing one end of the swing arm, the swing arm undergoes elastic deformation, causing the convex part to press down on the pressing column at the middle position. The pressing spring undergoes elastic deformation, and the pressing column triggers the function switch at the middle position. When it is necessary to switch between different function positions, by toggling the swing arm, the swing arm swings around the rotation center. The moving post slides from the central arc groove along the edge of the locking spring until it engages in an adjacent arc groove. Simultaneously, because the height of the two side pressing posts is higher than the central pressing post, when the swing arm moves the protrusion from the central position to the adjacent position, the protrusion contacts the top of the higher pressing post, continuously applying external force. This force is transmitted through the protrusion to the higher pressing post, overcoming the elastic resistance of the pressing spring. At this point, the protrusion squeezes the pressing post, causing the pressing spring to deform elastically, and the higher pressing post presses down, triggering the corresponding function switch. Therefore, the central pressing post is lower, requiring only pressing the swing arm to trigger; the two side pressing posts are higher, requiring a stronger external force to move the swing arm to trigger. This allows for rapid switching and reliable triggering between different function positions, preventing accidental triggering of different function switches due to external impact.

Detailed Implementation

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0025] Reference Figures 2 to 4 This utility model provides an anti-accidental touch toggle pressing assembly, including a swing arm 23 and a locking plate 24. The swing arm 23 and the locking plate 24 are rotatably connected. The side of the swing arm 23 near the locking plate 24 is provided with a follower post 231 and a protrusion 232. The locking plate 24 is provided with a locking spring 241. The edge of the locking spring 241 is provided with a plurality of arc grooves 242. The plurality of arc grooves 242 are smoothly transitioned between each other. The arc grooves 242 are used to lock the follower post 231. The locking spring 241 has a deformation space in the direction away from the follower post 231. The locking plate 24 is provided with a clearance position. The locking spring 241 is located in the clearance position. The clearance position is used to avoid the protrusion 232. The swing arm 23 is elastic.

[0026] When switching between different function levels is required, the swing arm 23 is moved, causing it to oscillate around its rotation center. The swing arm 23 drives the follower column 231 to slide along the edge of the locking spring piece 241 from one of the arc grooves 242 until it engages with the other arc groove 242. Then, by pressing one end of the swing arm 23, it elastically deforms, causing the protrusion 232 to move towards one side of the locking plate 24. The protrusion 232 triggers the switch for different function levels. This allows for blind operation in dark environments, enabling rapid switching and reliable triggering between different function levels.

[0027] Furthermore, when switching to different function levels, two actions are required: flicking and pressing the swing arm 23, to trigger the switch for the different function levels. This avoids accidental triggering of the switch for different function levels due to external impact.

[0028] In some preferred embodiments, the card plate 24 is also provided with a plurality of pressing springs 243, and pressing springs 243 are provided with pressing posts 244. The plurality of pressing springs 243 are located in the clearance position, and the plurality of pressing posts 244 are arranged in an arc with the rotation center of the swing arm 23 as the center. The plurality of pressing posts 244 correspond one-to-one with different function gear switches.

[0029] When one end of the swing arm 23 is pressed, the swing arm 23 undergoes elastic deformation. The swing arm 23 drives the protrusion 232 to press down on the pressing post 244. The pressing spring 243 undergoes elastic deformation, which in turn drives the pressing post 244 to trigger the corresponding function switch. The pressing spring 243 can absorb the impact force during pressing through elastic deformation, avoiding direct impact of the protrusion 232 on the function switch and improving the service life of the product.

[0030] In some preferred embodiments, the number of arc grooves 242 on the locking spring 241 is three, the number of pressing springs 243 and pressing posts 244 is the same as the number of arc grooves 242, the height of the middle pressing post 244 is lower than the height of the other two pressing posts 244, the protrusion 232 is a hemispherical structure, and the top of the pressing post 244 is a hemispherical structure.

[0031] In the initial state, the follower post 231 in the swing arm 23 is stuck on the arc groove 242 in the middle position. By pressing one end of the swing arm 23, the swing arm 23 undergoes elastic deformation. The swing arm 23 drives the protrusion 232 to press down the pressing post 244 in the middle position. The pressing spring 243 undergoes elastic deformation and drives the pressing post 244 to trigger the function switch in the middle position.

[0032] When the swing arm 23 is moved, the swing arm 23 swings around the rotation center. The swing arm 23 drives the follower column 231 to slide from the arc groove 242 in the middle position along the edge of the locking spring 241 until it is locked into the adjacent arc groove 242. At the same time, since the height of the other two pressing columns 244 is higher than that of the pressing column 244 in the middle position, when the swing arm drives the protrusion 232 to move from the middle position to the adjacent position, the protrusion 232 contacts the top of the higher pressing column 244 and continuously applies external force. The external force is transmitted to the higher pressing column 244 through the protrusion 232 and overcomes the elastic resistance of the pressing spring 243. At this time, the protrusion 232 squeezes the pressing column 244, the pressing spring 243 undergoes elastic deformation, the higher pressing column 244 presses down and triggers the corresponding function gear switch.

[0033] Therefore, the middle pressing post 244 is lower, and only the swing arm 23 needs to be pressed to trigger it; the two pressing posts 244 on both sides are higher, and a stronger external force is required to move the swing arm 23 to trigger it. This further avoids the accidental triggering of the switch of different function positions due to external impact.

[0034] It should be noted that the hemispherical structure at the top of the higher pressing post 244 forms a point contact with the hemispherical contact surface of the protrusion 232, which reduces frictional resistance, improves the smoothness of sliding, and facilitates the protrusion 232 to slide to the top of the higher pressing post 244, so that the higher pressing post 244 can be pressed down.

[0035] In some preferred embodiments, the first and last ends of the locking spring 241 are connected to the locking plate 24 to form a closed structure. The edge of the locking spring 241 has continuous undulating peaks and valleys, and the arc groove 242 is located in the valley.

[0036] Understandably, on the one hand, the closed-structure locking spring 241 can improve the overall rigidity, ensure that the locking spring 241 is subjected to uniform force, and improve the service life of the locking spring 241; on the other hand, when the swing arm 23 is turned, the follower column 231 slides out from the arc groove 242 of the current valley position and slides along the peak of the edge of the locking spring 241. At this time, when sliding over the peak position, it is necessary to overcome the resistance of the locking spring 241, which can provide the operator with an operating damping feel. Moreover, the smooth peak position can make the resistance during turning smooth. Then, the follower column 231 slides into the arc groove 242 of the adjacent valley position. At this time, the follower column 231 will instantly lose the resistance of the spring, so that the operator can feel a significant force drop, thereby feeling precise gear position tactile feedback, which is convenient for blind operation in dark environments.

[0037] In some preferred embodiments, the locking plate 24 is also provided with a lever 245, which is located within the closed structure of the locking spring 241. The lever 245 is clearance-fitted with the inner surface of the locking spring 241 to limit the maximum deformation displacement of the locking spring 241.

[0038] Understandably, when the swing arm 23 is actuated, the locking spring 241 undergoes elastic deformation under the force of the follower column 231 and is pressed against one side of the lever arm 245. The lever arm 245 provides a progressive reaction force, which can control the deformation rate of the locking spring 241. Thus, the deformation of the locking spring 241 can be controlled within the elastic range of the material, preventing plastic damage caused by excessive deformation of the locking spring 241 and improving the service life of the locking spring 241.

[0039] In some preferred embodiments, the rotation center of the swing arm 23 is coaxially arranged with the geometric center of the positioning plate 24, and there are two follower columns 231 and two protrusions 232. The two follower columns 231 and two protrusions 232 are symmetrically arranged along the rotation center of the swing arm 23, and there are two positioning springs 241. The two positioning springs 241 are symmetrically arranged along the center of the positioning plate 24.

[0040] Understandably, the symmetrical structure of the swing arm 23 can offset unilateral stress and improve its resistance to eccentric loads. At the same time, when one of the locking springs 241 fails, the other locking spring 241 can still maintain basic operation, improving the fault tolerance rate during operation.

[0041] In some preferred embodiments, both ends of the swing arm 23 are detachably connected to operation keys 25, which are used by the operator to toggle and press.

[0042] Understandably, the operation keys 25 at both ends can be adapted to the operator's left- or right-handed gun-holding habits, avoiding delays in gear switching caused by tactical posture adjustments. Moreover, the operation keys 25 have a distinct tactile feel, enabling the operator to quickly locate the position when flicking and pressing the operation keys 25.

[0043] Furthermore, the operation key 25 is provided with a slot, and the two ends of the swing arm 23 are folded outward and inserted into the slot, thereby enabling the operation key 25 to be quickly disassembled and assembled, improving assembly efficiency.

[0044] This utility model embodiment also provides a button device 2, including a tail cover housing 21, a PCB assembly 22, and the aforementioned anti-accidental touch toggle pressing assembly. A rotating shaft 211 is provided inside the tail cover housing 21, and the middle part of the swing arm 23 is rotatably connected to the rotating shaft 211. The tail cover housing 21 has two clearance holes for allowing the two ends of the swing arm 23 to protrude. A locking plate 24 is fixedly connected to the tail cover housing 21. One end of the rotating shaft 211 is connected to one side of the locking plate 24. The PCB assembly 22 is located on the side of the locking plate 24 away from the swing arm 23. The PCB assembly 22 includes a plurality of micro switches 221, and the plurality of micro switches 221 correspond one-to-one with a plurality of pressing posts 244.

[0045] Understandably, when the swing arm 23 is moved, the swing causes the protrusion 232 to move to the corresponding position of another pressing post 244. By pressing the operation key 25, the swing arm 23 undergoes elastic deformation, and the swing arm 23 causes the protrusion 232 to press down the pressing spring 243. The pressing spring 243 undergoes elastic deformation and causes the pressing post 244 to contact the corresponding micro switch 221, thereby switching and triggering the switch of different function levels.

[0046] Furthermore, the positioning plate 24 is mounted on the tail cover housing 21 by several screws. The tail cover housing 21 is provided with several mounting posts, each with a threaded hole. The positioning plate 24 is provided with several countersunk holes. The small holes of the countersunk holes allow the shank of the screw to pass through, and the countersunk head of the countersunk holes accommodates the head of the screw. The screw is threadedly connected to the threaded hole, thereby facilitating the assembly and disassembly of the positioning plate 24 and the toggle arm.

[0047] Furthermore, a washer 26 is provided between the swing arm 23 and the inner wall of the tail cover housing 21. The washer 26 is sleeved on the outer circumference of the rotating shaft 211, thereby avoiding direct contact between the swing arm 23 and the inner wall of the tail cover housing 21, reducing the coefficient of friction during rotation, reducing wear, and extending service life.

[0048] In some preferred embodiments, a silicone pad 27 is provided between the card slot plate 24 and the PCB assembly 22, and a first accommodating cavity 212 and a second accommodating cavity 213 are provided on the tail cover housing 21. The first accommodating cavity 212 is used to accommodate the card slot plate 24, and the second accommodating cavity 213 is used to accommodate the silicone pad 27.

[0049] Understandably, the first accommodating cavity 212 can limit the positioning of the card plate 24, and the second accommodating cavity 213 can limit the positioning of the silicone pad 27, ensuring the accurate installation position of the card plate 24 and the silicone pad 27. The silicone pad 27 can seal the PCB assembly 22, thereby preventing external dust and moisture from entering the PCB assembly 22 and improving the service life of the equipment.

[0050] Reference Figure 1 This utility model embodiment also provides a laser aiming device, including aiming device body 1 and the aforementioned button device 2, the button device 2 being disposed at the tail of aiming device body 1.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
