Description

Technical Field

[0002] Currently, toy tanks are one of the most common toys in life. In order to better let children understand the dynamic scene of a tank firing its cannon, toy developers often set a recoil structure between the turret and the cannon barrel on the toy tank. This allows the recoil structure to be linked with the vibration of the entire vehicle, simulating the scene of a real tank firing its cannon and generating recoil. However, the existing recoil structure of toy tanks has problems such as inconvenient installation, poor linkage between the cannon barrel, turret and the entire vehicle, poor simulation, and inability to simulate the dynamic scene of a tank firing its cannon and generating recoil.

[0003] There are currently no effective solutions to the problems of inconvenient installation, poor linkage between the cannon barrel, turret and the whole vehicle, poor simulation, and inability to simulate the dynamic scene of recoil generated when a tank fires. Utility Model Content

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] See Figures 1-4 This application provides a turret shell linkage vehicle recoil structure, installed on a toy tank, including a turret shell 100, a drive device 200, a transmission assembly 300, a resonance assembly 400, and a cannon 500. The turret shell 100 is fixed to the body of the toy tank. The resonance assembly 400 includes a fixing post 41, a spring 42, and a resonance seat 43. The fixing post 41, spring 42, resonance seat 43, drive device 200, and transmission assembly 300 are all disposed inside the turret shell 100. The cannon 500 is fixed to the front end of the turret shell 100. The drive device 200 is connected to the resonance seat 43 through the transmission assembly 300. The rear end of the fixing post 41 is fixed inside the turret shell 100, and the front end of the fixing post 41 is connected to the rear end of the resonance seat 43 through the spring 42. The front end of the resonance seat 43 is retractably disposed at the rear end of the cannon 500.

[0022] It should be noted that with this configuration, the drive unit 200 drives the resonance seat 43 to push and pull between the cannon barrel 500 and the fixed column 41 through the transmission component 300, causing the turret shell 100 to resonate, so that the toy tank vibrates to simulate the recoil of the cannon barrel 500 when firing. The turret shell 100, drive unit 200, transmission component 300, resonance component 400 and cannon barrel 500 are easy to install and the components fit tightly together. The drive motor converts the rotational speed into torque through the transmission gear set 33, which increases the reciprocating thrust of the resonance component 400 in the sleeve resonance area, thereby improving the linkage vibration effect of the cannon barrel 500, turret shell 100, resonance component 400 and the whole vehicle, improving the simulation and playability of the toy tank, and enhancing the attractiveness of the toy tank.

[0023] In order to achieve the purpose of driving the transmission assembly 300 and the resonance assembly 400, in some alternative embodiments, the driving device 200 is a drive motor, which is connected to the transmission assembly 300 via a rotating shaft.

[0024] It should be noted that this setup, using a drive motor as the power source, offers high precision.

[0025] To achieve precise transmission between the drive motor and the resonant assembly 400, in some optional embodiments, the transmission assembly 300 includes a crown gear 31, a compound gear 32, and a transmission gear set 33. One end of the crown gear 31 is sleeved on the shaft of the drive motor, and the other end of the crown gear 31 meshes with the crown teeth of the compound gear 32. The sawtooth teeth of the compound gear 32 mesh with one end of the transmission gear set 33, and the other end of the transmission gear set 33 is connected to the resonant seat 43. The drive motor drives the compound gear 32 to rotate through the crown gear 31, thereby driving the transmission gear set 33 to rotate synchronously, so that the transmission gear set 33 can transmit power to the resonant seat 43.

[0026] It should be noted that with this configuration, the drive motor and the resonant seat 43 can be precisely connected by using crown gear 31, compound gear 32 and transmission gear set 33. At the same time, the speed of the drive motor is converted into torque. The drive motor pulls the resonant seat 43 backward through crown gear 31, compound gear 32 and transmission gear set 33, compressing the spring 42. The spring 42 stores energy. When the drive motor stops working, the spring 42 releases the stored energy and rebounds. The resonant seat 43 is ejected by the spring 43 and impacts the rear end of the gun barrel 500, causing the turret housing 100 and the whole vehicle to resonate. This simulates the dynamic scene of the gun barrel 500 firing when it fires, and the turret housing 100 and the whole vehicle vibrating due to the recoil generated by the firing of the gun barrel 500.

[0027] To further achieve precise transmission between the drive motor and the resonant assembly 400, in some optional embodiments, the transmission gear set 33 includes a first transmission gear 331, a second transmission gear 332, and a third transmission gear 333. The compound gear 32, the first transmission gear 331, the second transmission gear 332, and the third transmission gear 333 are all rotatably disposed within the turret housing 100. The large teeth of the first transmission gear 331 mesh with the sawtooth teeth of the compound gear 32, the small teeth of the first transmission gear 331 mesh with the large teeth of the second transmission gear 332, the small teeth of the second transmission gear 332 mesh with the large teeth of the third transmission gear 333, and both the large teeth and small teeth of the third transmission gear 333 mesh with the resonant seat 43. The compound gear 32 drives the first transmission gear 331, the second transmission gear 332, and the third transmission gear 333 to rotate synchronously, so that the third transmission gear 333 transmits power to the resonant seat 43.

[0028] It should be noted that by using the meshing transmission of the first transmission gear 331, the second transmission gear 332 and the third transmission gear 333, the function of the gearbox is realized, the torque of the drive motor on the resonance seat is increased, and the pulling force of the barrel extension and retraction is improved.

[0029] To achieve a precise fit between the transmission gear set 33 and the resonance seat 43, in some optional embodiments, the resonance seat 43 includes a limiting sleeve 431 and a movable sleeve 432. The front end of the limiting sleeve 431 is housed in the rear end of the barrel 500, the front end of the movable sleeve 432 is housed in the rear end of the limiting sleeve 431, the front end of the spring 42 is housed in the rear end of the movable sleeve 432, and the rear end of the spring 42 is sleeved on the outside of the fixed post 41. The limiting sleeve 431 is connected to the large tooth of the third transmission gear 333, and the movable sleeve 432 is connected to the small tooth of the third transmission gear 333. A sleeve resonance region is formed between the fixed post 41 and the barrel 500. The third transmission gear 333 drives the limiting sleeve 431 and the movable sleeve 432 to extend and retract within the sleeve resonance region through the large and small teeth, respectively.

[0030] It should be noted that with this configuration, the third transmission gear 333 drives the limiting sleeve 431 to move forward or backward through the large tooth, and the third transmission gear 333 drives the movable sleeve 432 to move forward or backward synchronously through the small tooth, so that the limiting sleeve 431 and the movable sleeve 432 perform telescopic movement in the sleeve resonance area, resulting in precise transmission.

[0031] To further achieve a precise fit between the transmission gear set 33 and the resonance seat 43, in some optional embodiments, a limiting rack 433 is provided on the outer peripheral sidewall of the limiting sleeve 431, and a movable rack 434 is provided on the outer peripheral sidewall of the movable sleeve 432. A first limiting structure is provided between the limiting rack 433 and the movable rack 434, and the limiting rack 433 and the movable rack 434 are limited and connected by the first limiting structure. The limiting sleeve 431 meshes with the large tooth of the third transmission gear 333 through the limiting rack 433, and the movable sleeve 432 meshes with the small tooth of the third transmission gear 333 through the movable rack 434. The third transmission gear 333 moves in extension and retraction relative to the barrel 500 through the large tooth and the limiting sleeve 431, and the third transmission gear 333 moves in extension and retraction relative to the limiting sleeve 431 through the small tooth and the movable sleeve 432.

[0032] It should be noted that with this configuration, the limiting sleeve 431 is engaged with the large tooth of the third transmission gear 333 by the limiting rack 433, and the movable sleeve 432 is engaged with the small tooth of the third transmission gear 333 by the movable rack 434. The connection between the limiting rack 433 and the large tooth, and between the movable rack 434 and the small tooth, is achieved by meshing, which results in a high degree of fit and improves the precision between the third transmission gear, the limiting sleeve 431, and the movable sleeve 432.

[0033] In order to limit the movement area of ​​the movable sleeve 432 within the limiting sleeve 431, in some optional embodiments, the first limiting structure includes a first limiting groove 435 provided on the limiting rack 433 and a first limiting strip 436 provided on the movable rack 434. The first limiting strip 436 is movably disposed within the first limiting groove 435. The first limiting strip 436 and the first limiting groove 435 are used to prevent the movable sleeve 432 from dislodging when it retracts or extends relative to the limiting sleeve 431.

[0034] It should be noted that with this configuration, since the travel of the limiting rack 433 and the movable rack 434 is different, the movable rack 434 uses the first limiting strip 436 to be embedded in the first limiting groove 435 of the limiting sleeve 431. When the movable sleeve 432 strikes the barrel 500 or the compression spring 42 forward, the first limiting strip 436 and the first limiting groove 435 can restrict the front end of the movable sleeve 432 to always be embedded in the rear end of the limiting sleeve 431, and will not come out due to vibration, so that the movable sleeve 432 and the limiting sleeve 431 can be stably connected.

[0035] To limit the movement area of ​​the resonance seat 43 within the turret housing 100, in some optional embodiments, a second limiting structure is provided between the resonance seat 43 and the turret housing 100. The second limiting structure includes a second limiting strip 437 provided on the limiting sleeve 431 or the movable sleeve 432, and a second limiting groove 11 provided on the turret housing 100. The second limiting strip 437 is movably provided within the second limiting groove 11. When the limiting sleeve 431 and the movable sleeve 432 perform telescopic movements within the sleeve resonance area, the second limiting strip 437 moves along the setting direction of the second limiting groove 11 on the turret housing 100.

[0036] It should be noted that with this configuration, a second limiting strip 437 is provided on the limiting sleeve 431 or the movable sleeve 432, and a second limiting groove 11 is provided on the turret housing 100. When the limiting sleeve 431 and the movable sleeve 432 move within the turret housing 100, the second limiting strip 437 slides along the direction of the second limiting groove 11, thereby controlling the movement trajectory of the limiting sleeve 431 and the movable sleeve 432 within the turret housing 100 and improving transmission stability.

[0037] To achieve a stable fit between the gun barrel 500, the turret housing 100, and the limiting sleeve 431, in some optional embodiments, the gun barrel 500 includes a gun rod 51 and a tee connector 52. The turret housing 100 is provided with a receiving groove 12, and the tee connector 52 is fastened to the receiving groove 12. One end of the tee connector 52 is fixedly connected to the gun rod 51. The front end of the limiting sleeve 431 is provided with a connecting post 438, which is received in the other end of the tee connector 52. When the limiting sleeve 431 moves telescopically relative to the gun barrel 500, the connecting post 438 telescopically extends and retracts within the tee connector 52.

[0038] It should be noted that with this setup, two ports of the three-way connector 52 are used to limit and fix the gun barrel 51 and the connecting column 438 respectively, and the last port is used to fix it in conjunction with the receiving groove 12, thereby ensuring a stable connection between the gun barrel 500, the turret shell 100 and the limiting sleeve 431, and improving operational stability.

[0039] In order to achieve the purpose of stably fixing the drive device 200, transmission assembly 300, resonance assembly 400 and gun barrel 500 to the turret housing 100, in some optional embodiments, the turret housing 100 includes a first housing 13 and a second housing 14, which are fixedly connected by screws, and a receiving cavity is formed between the first housing 13 and the second housing 14. The tee connector 52, drive device 200, transmission assembly 300 and resonance assembly 400 are all housed in the receiving cavity.

[0040] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
