Description

Technical Field

[0002] A seesaw is a two-person children's toy. One person sits at each end of the seesaw, moving up and down. The seesaw works on the principle of leverage. The pressure exerted by the person on the seesaw is the driving force and the resistance. The distance from the person to the fixed point of the seesaw represents the driving arm and the resistance arm, respectively. Downward acceleration causes the upper side to move up and down.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] The high-safety seesaw disclosed in the present invention is mainly used in scenarios where the weight difference between the two sides is too large, and the lighter side of the seesaw will rise rapidly, resulting in the risk of collision and falling during uncontrolled rise.

[0020] Reference Figure 1-Figure 4 In a preferred embodiment, the dynamic balancing module 3 includes: A limiting guide frame 301 is fixedly connected to one side of the supporting base plate 1. A lifting fixture 303 is slidably connected to the interior of the limiting guide frame 301. Two mounting plates 304 are fixedly connected to one side of the lifting fixture 303. Both mounting plates 304 have mounting circular openings on one side. The interiors of the two mounting circular openings are connected to the same dynamic balancing wheel 305 via bearings. The horizontal buffer spring 302 has one side fixedly connected to one side of the support base 1 and the other side fixedly connected to one side of the lifting fixture seat 303 . The horizontal buffer spring 302 is located inside the limiting guide frame 301 .

[0021] In the present invention, the dynamic balancing module 3 further includes: The rotating shaft 306 is connected to the limiting guide frame 301 through a bearing. The outer portion of the rotating shaft 306 is fixedly connected to an angle balancing seat 307. Both sides of the angle balancing seat 307 respectively abut against the outer portion of the dynamic balancing wheel 305. The crossbeam 4 is fixedly connected to one side of the angle balancing seat 307. The outside of the crossbeam 4 is slidably connected to two balancing sleeves 317. The inside of the two balancing sleeves 317 is equidistantly distributed with extrusion springs 321 in a circular shape. One side of multiple extrusion springs 321 located on the same side is fixedly connected to the same U-shaped tooling rod 322. Circular holes 1 are opened on both sides of the multiple U-shaped tooling rods 322 at equal distances. The insides of the two opposite circular holes 1 are connected to the same roller 323 through bearings.

[0022] In the present invention, the dynamic balancing module 3 further includes: Two balancing weights 319 are fixedly connected to the outside of two balancing sleeves 317, and the outside of the two balancing sleeves 317 are fixedly connected to the tooling plates 318; A U-shaped linkage frame 308 is fixedly connected to the outside of the rotating shaft 306. A tool mounting frame 309 is fixedly connected to one side of the U-shaped linkage frame 308. Two circular holes 2 are provided on both sides of the tool mounting frame 309. The interiors of the two opposing circular holes 2 are connected to the same rotating cylinder 312 via bearings. The exteriors of the two rotating cylinders 312 are fixedly connected to limited position sleeves 313. In the present invention, the dynamic balancing module 3 further includes: The indicator rod 320 is fixedly connected to the outside of the rotating shaft 306. Two circular holes 3 are formed on both sides of the tooling mounting frame 309. The interiors of the two opposing circular holes 3 are connected to the same winding cylinder 310 through bearings.

When the left side sinks, the beam 4 drives the rotating shaft 306 to rotate counterclockwise, the indicator rod 320 tilts, the angle balance seat 307 presses the dynamic balancing wheel 305, pushes the lifting tooling seat 303 to compress the horizontal buffer spring 302, absorbs the initial impact, and reduces the shaking of the support base 1. The rotating shaft 306 drives the U-shaped linkage frame 308 to deflect, triggering the universal motor 3 on the right side. 14 releases the retractable rope 315, and the right telescopic spring 316 extends, pulling the tooling plate 318 to drive the balancing weight block 319 to slide to the right along the beam 4, increasing the counterweight on the right side of the light side. The retractable rope 315 is guided by the limiting sliding sleeve 313 to ensure that the movement trajectory of the tooling plate 318 is stable. After the counterweight block moves to the new balance point, the beam 4 tends to be horizontal, the indicator mark 320 returns to the center, and the universal motor 314 stops working. When the weight difference between the two is large, the center of gravity position is automatically adjusted through the dynamic balancing module 3 to avoid rapid lifting of the light side, thereby solving the risk of rapid rise and fall caused by imbalance of the traditional seesaw.

[0028] In a specific application scenario, when the heavier side seat 5 sinks, the downward pressure support arm 602 pushes the horizontal cylinder 603 downward, and the rotating block 1 605 drives the damping slide 608 to slide in the damping movable sleeve 607, compressing the damping spring 610 and consuming part of the kinetic energy. The horizontal cylinder 603 presses down the limiting track 609, pushing the buffer slider 613 to slide along the guide cylinder 614 and squeeze the offset spring 615. The movable downward pressure rod 616 hinges the movable block 617 to push the movable slide frame 611, so that the rubber roller 612 contacts the ground, and further absorbs the remaining impact force through elastic deformation. When the pressure is released, the damping spring 610 and the offset spring 615 release the stored energy, pushing each component back to its position, preparing for the next buffering, and forming a two-stage buffering protection through the stabilizing module 6, attenuating the downward force in stages to avoid ground impact, so that the device moves smoothly.

The right telescopic spring 316 stretches, pulling the tooling plate 318 to drive the balancing counterweight 319 to slide rightward along the beam 4, increasing the right counterweight on the light side. The retractable rope 315 is guided by the limiting sleeve 313 to ensure the stable movement trajectory of the tooling plate 318. After the counterweight moves to the new balance point, the beam 4 tends to be horizontal, the indicator mark 320 returns to the center, and the universal motor 314 stops working. When the heavier side seat 5 sinks, the downward pressure support arm 602 pushes the horizontal cylinder 603 downward, and the rotating block 1 605 drives the damping slide 608 to slide in the damping movable sleeve 607, compressing the damping spring 610 and consuming part of the kinetic energy.
