Abstract

A frictional energy accumulation and acceleration yo-yo, comprising two rotary members (1) and a connection shaft (2) connecting the two rotary members (1). The rotary members (1) each comprise a disc (11) and a lateral cap (12); the discs (11) spin relative to the lateral caps (12); each disc (11) is internally provided with a frictional energy accumulation mechanism (3); and one end of the frictional energy accumulation mechanism (3) is connected to the disc (11), and the other end is connected to the lateral cap (12). Upon pinching the lateral caps (12), the discs (11) contact an external contact surface and create friction such that the frictional energy accumulation mechanisms (3) accumulate energy; once energy accumulation is complete, and when the discs (11) are separated from the external contact surface, the frictional energy accumulation mechanism (3) releases energy and drives the two discs (11) to spin simultaneously in the direction opposite the direction in which the friction was created; then the lateral caps (12) are released to allow the entire yo-yo to spin. Even if the string is too short, the yo-yo can still spin at a high rate of speed and is not subject to acceleration area requirements. Thus, even shorter persons can fully enjoy the yo-yo.

Description

a yo-yo that accelerates the acceleration of energy storage

Technical field

The invention relates to a yo-yo, in particular to a yo-yo which accelerates the acceleration of energy storage.

Background technique

At present, the yo-yo on the market basically consists of two rotating bodies and connecting shafts connecting two rotating bodies, and then winding the rope in the middle of the two rotating bodies, so that the yo-yo can be quickly at the end of the rope by forcibly throwing the yo-yo ball Turn. However, due to the limitations of the yo-yo recycling system and the bearing system, users with low heights are basically unable to use the rope to throw the ball for play, because the length of the rope is proportional to the height of the user. For users with higher heights, after the ball is dropped, the ball has enough acceleration area to accelerate the ball to a certain speed, and complete the play of various moves; but for the player with low height, the acceleration area of the ball is thrown away. Too short, the ball does not spin fast enough to complete the move.

After the side cover 12 of the two rotating bodies 1 is pinched by hand, the disk body 11 is brought into contact with the external contact surface and frictionally rolled to realize energy storage for the motorized energy storage mechanism 3. When the disk body 11 leaves the external contact surface after the energy storage is completed, the disk body 11 is removed from the external contact surface. The movable energy storage mechanism 3 releases energy and drives the two disk bodies 11 to rotate synchronously in the opposite direction of the rolling direction. At this time, the side cover 12 is loosened to realize the rotation of the entire yo-yo ball, so that it is not necessary to use the rope to throw the yo-yo ball to rotate it. Even if the rope is too short to throw the sphere ball, it can rotate at high speed without being affected by the acceleration area of the throwing ball. Therefore, even the player with low height can play the yo-yo to enjoy the various fancy moves. The playing needs of players of different ages and heights, and relative to existing Yo-yo adds a new mode of operation and a new play, more fun, more diverse gameplay.

As shown in FIG. 3, in this embodiment, a limiting mechanism 4 and an overload protection mechanism 5 are disposed in each of the disk bodies 11, and the limiting mechanism 4 and the overload protection mechanism 5 are disposed on the side cover 12 and the motorized storage. Can be connected between the positions of the mechanism 3. The limiting mechanism 4 of this embodiment includes four limiting blocks 41 and a supply base. The mounting plate 42 mounted on the finite block 41 and the gear plate 43 recessed with the inner helical teeth 431 are provided with four pin holes 421 on the bottom surface of the mounting plate 42, and the limiting block 41 is inserted into the pin holes 421 through the pins 9. The bottom plate of the mounting plate 42 is rotatably connected to the bottom surface of the mounting plate 42 and the mounting plate 42 is protruded. The gear plate 43 is placed on the limiting block 41 to realize the limiting claw of the limiting block 41 in the inner helical tooth 431, so the gear plate 43 is reversed. When the limit is rotated in the direction of the block 41, the limiting claw is caught in the inner helical tooth 431 so that the gear plate 43 cannot be rotated, so that the gear plate 43 can only be rotated in one direction, and the gear plate of the limiting mechanism 4 is realized. 43 is connected to one end of the motor-operated energy storage mechanism 3; the overload protection mechanism 5 of this embodiment includes a ring 51 having a convex tooth 511 on a circular arc surface and an inner gear ring 52 meshing with the convex tooth 511. The inner ring gear 52 is disposed on the top surface of the mounting plate 42, that is, the mounting plate 42 and the inner gear ring 52 are integrally formed, so that the number of components can be reduced, the cost is reduced, and the structure is more compact. An elongated convex key 512 is disposed on the side cover 12 correspondingly with an elongated keyway 121 and the elongated convex key 512 is coupled to the circle. There are three convex teeth 511 of 51. When the energy storage mechanism 3 is overloaded, that is, when the user rolls the friction until it is basically unable to roll, the ring 51 is deformed by force. When the protruding tooth 511 is disengaged from the internal gear 52, the side cover 12 cannot restrain the mounting plate 42 at this time, so that the entire limiting mechanism 3 is in an vacant state, so that the disk body 11 can be rotated, thereby causing the frictional energy storage mechanism 3 to be activated. Stop storing energy.

As shown in FIG. 2 and FIG. 3, the energy storage mechanism 3 of this embodiment includes an energy storage spring 31 and a barrel 32, wherein the energy storage spring 31 is a spiral spring and is placed in the barrel 32. The outer end is fixed to the barrel 32. The barrel 32 includes a box body 322 and a cover 321 . The edge of the box 322 is provided with a notch 323. The outer end of the energy storage spring 31 is fixed to the gap 323. The cover body 321 is provided with three hole-shaped lugs 324. The cover body 321 is placed on the box body 322, and then aligned with the screw holes on the disk body 11 through the holes in the lug 324 and fixed by a screw connection. A through hole 320 is defined in the middle of the box 32; a lower portion of the gear plate 43 of the limiting mechanism 4 is correspondingly provided with a stud 430 passing through the through hole 320 into the barrel 32, and the outer ring of the stud 430 is provided with three spaces. An arcuate piece 432 is disposed and has a gap with the stud 430. The lower end of each of the curved pieces 432 is provided with a hook 433. When the stud 430 of the gear plate 43 is inserted into the through hole 320 of the barrel 32 The hook 433 extends beyond the through hole 320 and fastens the edge of the hole to realize the connection of the gear plate 43 to the barrel 32, and the inner end of the energy storage spring 31 is engaged with the curved piece 432 of the gear plate 43; The gear plate 43 A bearing seat 434 is disposed in the middle, and a bearing 6 is mounted on the bearing seat 434. The intermediate hole of the bearing 6 is inserted into the connecting shaft 2. The disk body 11 of this embodiment A friction ring 7 is connected to the edge of the disk, and the friction coefficient of the friction ring 7 is larger than that of the disk body 11. The friction ring 7 is provided with a counterbore, and the screw hole passes through the counterbore and the disk mouth of the disk body 11. The screw hole of the edge is screwed to realize the locking, and the diameter of the friction ring 7 is larger than the diameter of the disk mouth of the disk body 11, so that the friction ring 7 is in contact with the contact surface during frictional energy storage, which not only better protects the disk. The body 11 is protected from friction and damage, further improving the service life of the yo-yo, and the friction coefficient of the friction ring 7 is large, so that the friction does not slip during rolling friction, and the energy storage effect is improved, and the friction is only required to be replaced when the energy storage effect is lowered. In addition, a decorative ring edge 8 is sleeved on the outer end surface of the friction ring 7 , and the decorative ring edge 8 is provided with an arc-shaped convex strip 81 downwardly, and the friction ring 7 is correspondingly provided with an arc groove. The hole 71 is inserted into the curved ridge 81 to realize the side of the decorative ring 8 fixed to the friction ring 7.

As shown in FIG. 4, the side cover 12 of this embodiment is placed on the outer end surface of the friction ring 7, and a counterbore 122 is opened in the middle of the side cover 12, and a circle is provided in the middle of the strip-shaped convex key 512 of the ring 51. a hole 513, and a strip-shaped keyway 514 smaller than the strip-shaped convex key 512 is recessed at the bottom of the strip-shaped convex key 512. The mounting disk 42 of the embodiment and the protruding post 430 of the gear plate 43 are respectively provided with a through hole. For the connecting shaft to pass through, the end of the connecting shaft 2 of this embodiment is designed as a strip-shaped male key 21 matching the strip key groove 514 at the bottom of the ring 51, and a screw hole 22 is provided in the middle of the strip-shaped male key 21. After the connecting shaft 2 passes through the through hole of the mounting plate 42 and the gear plate 43, the end strip-shaped male key 21 is inserted into the strip key groove 514 of the ring 51, and passes through the side cover 12 from the outside of the side cover 12 through a bolt. The counterbore 122 and the circular hole 513 of the ring 51 are screwed into the screw holes 22 of the connecting shaft 2 to be connected as shown in FIG. In addition to this, the yo-yo of this embodiment is provided with a main bearing at a position between the two rotating bodies 1, and a yo-yo rope is wound around the main bearing.

The yo-yo is played as follows:

Wrap the yo-yo rope, then use your fingers to pinch the side cover 12 on both sides of the yo-yo ball, then place the yo-yo on the external contact surface such as the table or the floor, let the friction ring 7 contact the contact surface, and then try to One of the directions is scrolling. If it is very easy to roll forward, and does not feel too much resistance, it means that the direction of scrolling is not the direction of energy storage for the motorized energy storage mechanism 3. The rolling resistance is due to the gear of the limiting mechanism 4. The disk 43 is not restricted by the restriction block 41, that is, the gear plate 43 can be rotated relative to the side cover 12, and even if the gear plate 43 and the energy storage spring 31 and the barrel 32 are rotated in synchronization with the rolling of the disk 11, the energy storage is performed. The spring 31 cannot store energy; then it can be judged that it is rolling in the opposite direction, that is, rolling backward, and at this time, the gear plate 43 is restricted to the block 41 and cannot be rotated, so the energy storage spring 31 is stored. The inner end portion is fixed, and the outer end portion is rotated by the rolling of the disk body 11, so that the energy storage spring 31 starts to store energy, and when scrolling backward to substantially fail to roll, the energy storage spring 31 is full. At this time, if the driving force continues to roll backward, the disk 51 is deformed too much and the convex tooth 511 is disengaged from the internal gear 52 of the mounting plate 42, thereby forming the mounting plate 42 and the gear plate 43. It can rotate with the rolling, effectively protecting the energy storage spring 31 from damage due to excessive energy storage; after the energy storage is full, use the finger of the other hand to cover the rope, and then take the yo-yo hand to the yo-yo When the contact surface is removed, the frictional resistance of the friction ring 7 is released, and the energy storage spring 31 starts to be reversed in the opposite direction to release energy, thereby causing the disk body 11 to start rotating in the opposite direction, and the gear plate 43 is not restricted in the opposite direction. The block 41 is also constrained to rotate synchronously. At this time, the hand holding the yo-yo is released, and the yo-yo falls along the rope, and finally rotates at the end of the rope at a high speed, thereby performing various moves.

Although the present invention has been described with reference to the specific embodiments, this description is not intended to limit the invention. Other variations to the disclosed embodiments are contemplated by those skilled in the art in light of the description of the invention.
