Description

Technical Field

[0001] This invention belongs to the technical field of light weapons shooting training equipment, and specifically relates to a multi-functional target drone. Background Technology

[0002] To make small arms shooting training more realistic, target drones are required to have functions such as rotation, tilting, and elevation to simulate the enemy's random movements and concealment in actual combat, thus improving soldiers' shooting skills and reaction capabilities. Existing ordinary target drones generally only possess one of these functions, requiring the use of multiple drones in combination for training requiring various shooting modes, resulting in high costs and low efficiency. Multi-functional target drones combine rotation, tilting, and elevation functions into a single device, reducing costs and increasing efficiency. However, existing multi-functional target drones use a single motor to drive each function, resulting in a larger overall size and weight, more complex control, and reduced efficiency in shooting training. Summary of the Invention

[0003] In view of the shortcomings of existing technologies, a multi-functional target machine is proposed to solve the technical problems of existing multi-functional target machines, such as having a large number of drive motors, large size of drive components, complex control, heavy weight, and low shooting training efficiency.

The power source can move along the straight line, and each movement drives only one set of worm gear units. The three sets of worm gear units are respectively connected to the rotating assembly, the tilting assembly, and the lifting assembly to realize the rotation, tilting, and lifting operations of the target surface.

[0007] Furthermore, the left and right sides of the target surface are respectively connected to a sliding rod, the sliding rod is sleeved inside the sliding cylinder, and the sliding rod can slide relative to the sliding cylinder, the sliding cylinder is movably connected to the base.

[0008] Furthermore, a rotatable support plate is provided above the base, and the transmission assembly is located above the support plate.

The plug is fixedly connected to the mounting through hole. A portion of the retaining pin is located outside the mounting through hole. The two ends of the spring are respectively connected to the retaining pin and the plug.

[0011] Furthermore, the contact area between the spline and the locking pin is provided with a guide slope, and the locking pin is provided with a limiting step to prevent it from disengaging from the mounting through hole.

[0012] Furthermore, the worm gear is connected to the support plate via a worm gear bracket that is rotatably connected to it. The worm gear bracket is provided with a slide rail, and the slide rail is provided with a telescopic element. The movable end of the telescopic element is connected to the power source.

[0013] Furthermore, the base is provided with a synchronous pulley fixedly connected thereto, one of which is connected to the synchronous pulley via a synchronous belt drive.

[0031] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0032] According to an embodiment of the present invention, a multi-functional target machine is provided. Please refer to [link / reference]. Figure 1 , Figure 2 It includes a target surface 1, a transmission assembly, a rotation assembly, a tilting assembly, and a lifting assembly, wherein the target surface 1 is connected to the rotation assembly, the tilting assembly, and the lifting assembly in a transmission manner.

[0033] The transmission assembly includes three sets of worm gear units driven by the same power source 13. The worms of the three sets of worm gear units are located on the same straight line. The power source 13 can move along the straight line, and each movement drives only one set of worm gear units. The three sets of worm gear units are respectively connected to the rotating assembly, the tilting assembly, and the lifting assembly to realize the rotation, tilting, and lifting operations of the target surface 1.

[0034] It should be noted that the power source 13 can move along a straight line, and each movement only drives one set of worm gear units. That is, when the power source 13 is engaged with one set of worm gear units, the power source 13 is in a disengaged state from the other two sets of worm gear units. The three sets of worm gear units are respectively connected to the rotating component, the tilting component, and the lifting component. Only one power source 13 is needed to realize the rotation, tilting, and lifting operations of the target surface 1. The structure is compact, lightweight, and low-cost, which improves training efficiency.

[0035] For the multi-functional target machine in this embodiment, please refer to... Figures 1 to 3 The lifting assembly includes a slide rod 3 and a slide cylinder 6. The left and right sides of the target surface 1 are respectively connected to the slide rod 3. The slide rod 3 is sleeved inside the slide cylinder 6 and can slide relative to the slide cylinder 6. The slide cylinder 6 is movably connected to the base 9.

[0036] Specifically, target rods 2 are fixedly connected to the left and right sides of target surface 1, target rods 2 are fixedly connected to slide rods 3, a first linear bearing 19 is installed at the bottom of slide rod 3, a second linear bearing 4 is installed at the top of slide cylinder 6, slide rod 3 can move up and down inside slide cylinder 6, and at the same time, the bottom of slide cylinder 6 is movably connected to base 9.

[0037] For the multi-functional target machine in this embodiment, please refer to... Figure 1 , Figure 2 , Figure 5 as well as Figure 9 A rotatable support plate 21 is provided above the base 9, and the transmission assembly is located above the support plate 21. The transmission assembly is situated inside the first protective shell 8 to enhance safety. Furthermore, a control module, such as a circuit board, is housed inside the second protective shell 7. The first protective shell 8 and the second protective shell 7 are fixedly connected to the support plate 21 by bolts.

[0038] Specifically, a connecting shaft 50 is provided between the pallet 21 and the base 9. Both ends of the connecting shaft 50 are equipped with tapered roller bearings 49. A base bearing seat 52 is provided outside the tapered roller bearings 49, and the base bearing seat 52 is fixed on the base 9. In other words, the pallet 21 and all components mounted on the pallet 21 can rotate relative to the base 9.

[0039] For the multi-functional target machine in this embodiment, please refer to... Figure 2 , Figure 4 , Figure 6 as well as Figure 7 The power source 13 has a drive shaft 33 at its output end. The drive shaft 33 is located inside the worm gear and can move along the worm gear axis. The worm gear has a spline inside, and the drive shaft 33 has a spring pin that cooperates with the spline. A synchronous pulley coaxial with the worm gear unit is located below the support plate 21. Preferably, the power source 13 is a stepper motor.

[0040] Specifically, the worms in the three worm gear units are the first worm 25, the second worm 26, and the third worm 27. The first worm 25 is paired with the first worm wheel 22, the second worm 26 is paired with the second worm wheel 23, and the third worm 27 is paired with the third worm wheel 24. Meanwhile, the first worm wheel 22 is connected to the top end of the first shaft 46 by a key, and the bottom end of the first shaft 46 is connected to the first synchronous pulley 43 by a key. The first synchronous pulley 43 is a grooved wheel. The second worm wheel 23 is connected to the top end of the second shaft 47 by a key, and the bottom end of the second shaft 47 is connected to the second synchronous pulley 44 by a key. The second synchronous pulley 44 can be a synchronous belt pulley. The third worm wheel 24 is connected to the top end of the third shaft 48 by a key, and the bottom end of the third shaft 48 is connected to the third synchronous pulley 45 by a key. The third synchronous pulley 45 is a grooved wheel. In addition, the first shaft 46, the second shaft 47, and the third shaft 48 are fixed to the support plate 21 by bearing seats 37. In other words, the first synchronous pulley 43 rotates synchronously with the first worm gear 22, the second synchronous pulley 44 rotates synchronously with the second worm gear 23, and the third synchronous pulley 45 rotates synchronously with the third worm gear 24.

[0041] The output shaft of the power source 13 is fixedly connected to the drive shaft 33 via a set screw. The drive shaft 33 is coaxially clearance-fitted with the first worm 25, the second worm 26, and the third worm 27, allowing the drive shaft 33 to move axially within the worms. The first worm 25, the second worm 26, and the third worm 27 are fixed to the support plate 21 via four worm supports 28. The first worm 25, the second worm 26, and the third worm 27 are rotatably connected to the worm supports 28 respectively.

[0042] It should be noted that the first worm 25 has a first spline 30 inside, the second worm 26 has a second spline 31 inside, and the third worm 27 has a third spline 32 inside. The drive shaft 33 has three spring pins (the first spring pin 34, the second spring pin 35, and the third spring pin 36, respectively). During the axial movement of the drive shaft 33, the splines and spring pins cooperate to transmit the rotational power of the drive shaft 33 to the corresponding worm.

[0043] For the multi-functional target machine in this embodiment, please refer to... Figure 2 , Figure 4 , Figures 6 to 8 The drive shaft 33 has a mounting through hole for placing the spring pin along its radial direction. Taking the first spring pin 34 as an example, it includes a retaining pin 341, a spring 342 and a plug 343. The plug 343 is fixedly connected to the mounting through hole. A portion of the retaining pin 341 is located outside the mounting through hole. The two ends of the spring 342 are respectively connected to the retaining pin 341 and the plug 343. The retaining pin 341 is provided with a limiting step to prevent it from disengaging from the mounting through hole.

[0044] like Figure 6 As shown, the second spring pin 35 engages with the second spline 31, the first spring pin 34 disengages from the first spline 30, and the third spring pin 36 disengages from the third spline 32. When the drive shaft 33 rotates, the second spring pin 35 engages with the second spline 31, and the second worm 26 rotates with the drive shaft 33, while the first worm 25 and the third worm 27 do not rotate. When the drive shaft 33 moves axially to the right, the second spring pin 35 disengages from the second spline 31, and the third spring pin 36 gradually engages with the third spline 32. To facilitate the engagement, a guide slope is provided at the contact point between the spline and the locking pin 341. During engagement, the locking pin 341 can move downwards along the guide slope, compressing the spring 342. When the drive shaft 33 rotates, the locking pin 341 is pushed into the spline groove by the spring 342, completing the engagement of the third spring pin 36 with the third spline 32. The third worm 27 can then rotate with the rotation of the drive shaft 33. Similarly, the engagement process of the first spring pin 34 and the first spline 30 is the same as above. By moving the drive shaft 33 axially to the left, the engagement of the first spring pin 34 and the first spline 30 is completed, thereby transmitting the power of the drive shaft 33 to the corresponding worm gear.

[0045] For the multi-functional target machine in this embodiment, please refer to... Figure 2 , Figure 4 as well as Figure 6 The worm gear support 28 is provided with a slide rail 12, and a telescopic element 11 is provided on the slide rail 12. The movable end of the telescopic element 11 is connected to the power source 13. Preferably, the telescopic element 11 is an electric push rod.

[0046] Specifically, the power source 13 is fixedly connected to the connector 20, which is connected to both the slider 14 and the telescopic element 11. The slider 14 is connected to the slide rail 12 via a sliding pair and can move along the slide rail 12. The telescopic element 11 is fixed to the slide rail 12 via a fixing plate 10, and the slide rail 12 is fixed to the worm gear bracket 28 via screws. All four worm gear brackets 28 are fixed to the support plate 21. In other words, by controlling the extension and retraction of the telescopic element 11, the power source 13 and the slider 14 can be controlled to move along the slide rail 12, and the drive shaft 33 can be moved synchronously.

[0047] For the multi-functional target machine in this embodiment, please refer to... Figure 1 , Figure 4 , Figure 7 , Figure 9 as well as Figure 11 The base 9 is provided with a synchronous pulley 51 fixedly connected to it, and one of the synchronous pulleys is connected to the synchronous pulley 51 by a synchronous belt drive.

[0048] Specifically, the synchronous pulley 51 is fixed to the chassis bearing seat 52 by a set screw. When the second worm 26 rotates, the second worm wheel 23 and the second synchronous pulley 44 rotate accordingly. The second synchronous pulley 44 is connected to the synchronous pulley 51 by a synchronous belt 57. Since the synchronous pulley 51 is fixed to the chassis bearing seat 52, when the second synchronous pulley 44 rotates, the support plate 21 will rotate relative to the base 9, realizing the rotation function of the target surface 1.

[0049] For the multi-functional target machine in this embodiment, please refer to... Figure 1 , Figure 2 as well as Figure 12 A cross brace is connected between the two slide cylinders 6. The cross brace is hinged to the support plate 21. A lifting and tilting shaft 17 perpendicular to the cross brace is provided. Both ends of the lifting and tilting shaft 17 are connected to lifting and tilting wire ropes. The lifting and tilting wire ropes are fixed to both sides of one of the synchronous pulleys.

[0050] Specifically, the cross brace is connected to the reversing shaft 17 via a key, and the cross brace is hinged to the first bracket 15 and the second bracket 16. The first bracket 15 and the second bracket 16 are fixed on the support plate 21. The two ends of the reversing shaft 17 are respectively fixed to the first reversing wire rope 541 and the second reversing wire rope 542. The first reversing wire rope 541 and the second reversing wire rope 542 are fixed to both sides of the third synchronous pulley 45 (using a grooved pulley) via the third friction reducing block 561, the fourth friction reducing block 562 and the second wire rope guide frame 59.

[0051] In use, when the third synchronous pulley 45 rotates forward, the first tilting wire rope 541 is gradually released, the second tilting wire rope 542 is tightened, the tilting shaft 17 rotates forward, the slide 6 rotates forward, and the target surface 1 is tilted down. The target surface 1 is erected by reversing the above process, thus realizing the tilting and lifting function of the target machine.

[0052] For the multi-functional target machine in this embodiment, please refer to... Figure 1 , Figures 10 to 12 The slide bar 3 is connected to two lifting steel wire ropes, which are fixed to both sides of one of the synchronous pulleys.

[0053] Specifically, the slide bar 3 is fixedly connected to the first lifting wire rope 531 and the second lifting wire rope 532. The first lifting wire rope 531 and the second lifting wire rope 532 are respectively led out from the holes 5 at the upper and lower ends of the slide cylinder 6, and fixedly connected to both sides of the first synchronous pulley (using a grooved pulley) 43 through the third wire rope guide frame 18, the first wear-reducing block 551, the second wear-reducing block 552, and the first wire rope guide frame 58.

[0054] In use, when the first synchronous pulley 43 rotates forward, the first lifting wire rope 531 is gradually released, and the second lifting wire rope 532 is tightened. The second lifting wire rope 532 pulls the slide bar 3 downward along the slide cylinder 6, thus lowering the target surface 1. The process of the target surface 1 rising is the reverse of the above process, thereby realizing the lifting function of the target machine.

[0055] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
