Technical Field

[0001] The present invention relates to a rotating system, and particularly to a pulling flywheel rotating system. Background Art

[0002] Existing flywheel-driven toys and fighting gyroscopes are separate toys. The flywheel drive and the gyroscope are two independent systems, which cannot meet the requirements of game modes and functional cooperation, and their playing methods and functions are relatively single. Summary of the Invention

[0003] To make up for the above deficiencies, the present invention provides a pulling flywheel rotating system, which can combine a flywheel-driven toy and a fighting gyroscope into one, making the toy have more playing methods and more interesting.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a pulling flywheel rotating system, including a main body, a movable member, a flywheel, a rotating member and a driving device. The movable member is fixedly installed on the main body and can adjust its position. The flywheel is rotatably installed on the movable member. At least two rotating members are respectively fixedly sleeved on the outer circumference of the flywheel or coaxially fixed on the axial end face of the flywheel. When the movable member changes its installation position, different rotating members can contact with a supporting surface (generally the ground or a tabletop, etc.), and the symmetry center of the rotating member in contact with the supporting surface is located on the vertical line where the center of gravity of the entire rotating system is located. The driving device can drive the flywheel to rotate.

[0005] As a further improvement of the present invention, the movable member is installed on the main body and can rotate a set angle around a rotation axis perpendicular to the axis of the flywheel, and a positioning member is also provided. The positioning member can keep the movable member fixedly connected to the main body at different angles.

[0006] As a further improvement of the present invention, the positioning member includes a first buckle provided at different positions on the movable member and a second buckle fixedly provided on the main body. The second buckle can be snap-connected to any one of the first buckles. The first buckle is one of a convex point, a button or a stop block, and the second buckle is one of a groove matching the convex point, a jack matching the button, an inverted buckle or an engaging tooth matching the stop block.

[0007] As a further improvement of the present invention, the rotating member is a tire sleeved on the outer circumference of the flywheel and an axle head coaxially and fixedly installed on the axial end face of the flywheel.

[0008] As a further improvement of the present invention, the driving device includes a transmission mechanism and a manual driver. The manual driver can provide rotational energy to the main shaft through the transmission mechanism.

[0009] As a further improvement of the present invention, the transmission mechanism is a gear transmission mechanism. The power of the gear transmission mechanism is transmitted to the flywheel. The manual driver is a pull bar with a rack formed on one side. There is a pull bar channel on the movable member. The pull bar can be inserted into the pull bar channel, and the pull bar in the pull bar channel can mesh with the gear in the gear transmission mechanism for transmission.

[0010] As a further improvement of the present invention, the gear transmission mechanism includes a main gear coaxially and fixedly installed on the flywheel, a secondary gear meshing with the main gear for transmission, and an acceleration gear coaxially fixed to the secondary gear. The number of teeth of the acceleration gear is less than that of the secondary gear, and the number of teeth of the secondary gear is less than that of the main gear. The pull bar meshes with the acceleration gear for transmission.

[0011] As a further improvement of the present invention, the main gear is a 0.5 module 10-tooth gear, the secondary gear is a 0.5 module 20-tooth gear, the acceleration gear is a 0.7 module 8-tooth gear, and the pull bar is a 0.7 module rack.

[0012] As a further improvement of the present invention, the flywheel is a metal flywheel, and the diameter of the flywheel is 27.8 mm - 35 mm.

[0013] As a further improvement of the present invention, the movable member is a hollow housing structure, and is also provided with a flywheel rotating shaft and a gear mounting disc. Both ends of the flywheel rotating shaft are fixedly installed on two opposite inner side walls of the hollow housing. The flywheel is axially fixed and can rotate circumferentially and is sleeved outside the flywheel rotating shaft. The gear mounting disc is fixedly installed inside the movable member. The gear mounting disc is provided with an axial center hole and a long strip-shaped gear mounting hole. The axial center hole is for the main gear installed at one axial end of the flywheel to pass through. The long strip-shaped gear mounting hole extends radially along the axial center hole. On one side wall inside the movable member, there is also a long strip gear mounting groove opposite to the position of the gear mounting hole. Both ends of the rotating shaft of the secondary gear can be rotatably inserted into the long strip-shaped gear mounting hole and the long strip gear mounting groove respectively.

[0014] The beneficial technical effects of the present invention are as follows: By providing a movable member capable of adjusting its position on the body, and by adjusting the position of the movable member, the rotating members at different positions of the flywheel on the movable member are in contact with the support tabletop. The rotating members rotate smoothly and stably around their own rotating shafts. The contact of different rotating members with the support tabletop can convert the toy between a flywheel car and a battle top, making the toy have more playing methods and more interesting. Moreover, the present invention also adopts special gear walls and flywheel specifications, making the rotation of the flywheel durable and high-speed. During the rotation process, the entire rotation system is balanced and stable. When playing, it can be quickly converted between different forms according to needs without any tools.

[0025] Embodiment: A flywheel rotation system includes a main body 13, a movable member, a flywheel 5, a rotating member, and a driving device. The movable member is fixedly installed on the main body 13 in a position - adjustable manner. The flywheel 5 is rotatably installed on the movable member. At least two rotating members are respectively fixedly sleeved on the outer circumference of the flywheel 5 or coaxially fixed on the axial end surface of the flywheel 5. When the movable member changes its installation position, different rotating members can contact the support surface (generally the ground or a tabletop, etc.), and the symmetry center of the rotating member in contact with the support surface is located on the vertical line where the center of gravity of the entire rotating system lies. The driving device can drive the flywheel 5 to rotate. When in use, the movable member can be fixedly connected to the main body 13 at different positions, so that the rotation centers of different parts of the rotating member on the movable member are located on the vertical line where the center of gravity of the entire rotating system lies. When the driving device drives the flywheel 5 to rotate, the rotating member can keep the entire rotating system balanced during high - speed rotation. And when each rotating member located on the vertical line of the center of gravity of the entire system rotates in contact with the ground, different performances of the entire rotating system can be formed, thereby enabling the entire system to form a variety of changeable forms and making the play process more interesting.

[0026] The movable member can be rotatably mounted on the main body 13 about a rotation axis perpendicular to the axis of the flywheel 5 by a set angle, and a positioning member is further provided. The positioning member can keep the movable member fixedly connected to the main body 13 at different angles. When the rotating member is mounted on the axial end face of the flywheel 5, it contacts the ground to form a rotating support point when rotating synchronously with the flywheel 5. When the rotating member is mounted on the outer circumferential side wall of the flywheel 5, it contacts the ground to form a forward and backward rolling when rotating synchronously with the flywheel 5. The optimal rotation angle of the movable member on the main body 13 is 90 degrees. The movable member can be fixedly connected to the main body 13 through the positioning member at two positions of 0 degree and 90 degrees. By switching between the two angles of 0 degree and 90 degrees, the rotating member located on the axial end face of the flywheel 5 and the rotating member located on the outer circumferential side wall of the flywheel 5 alternately contact the ground.

[0027] The positioning member includes a first buckle 15 provided at different positions of the movable member and a second buckle 16 fixedly provided on the main body 13. The second buckle 16 can be snap-connected to any one of the first buckles 15. The first buckle 15 is one of a bump, a button or a stopper, and the second buckle 16 is one of a groove matching the bump, a jack matching the button, an inverted buckle or a meshing tooth matching the stopper. The snap connection between the first buckle 15 and the second buckle 16 realizes the quick connection between different parts of the movable member and the main body 13. Of course, in addition to the snap connection, a connecting member can also be used for connection.

[0028] The rotating member is a tire 3 sleeved on the outer circumference of the flywheel 5 and a shaft head 10 coaxially and fixedly installed on the axial end face of the flywheel 5. During use, when the tire 3 contacts the ground, it will roll along the ground, and the entire rotating system forms a small car, which can run forward in a straight line or an arc. Generally, it is designed to run forward in a straight line. At this time, it is a charging / racing game mode. When the shaft head 10 contacts the ground, the entire rotating system forms a top. At this time, it is a rotating / fighting collision game mode. The shaft head 10 can be detachably installed and positioned on the axial end face of the flywheel 5, which is convenient for replacing different types of shaft heads 10 according to the combat needs. The main body 13 can be made into the shape of a small car, and headlights 11, detachable steering handles 12, etc. can also be installed on the small car. In addition to the shape of a small car, the main body 13 can also be in the shape of a robot or an airplane, etc., to meet the playing needs of different children.

[0029] The driving device includes a transmission mechanism and a manual driver. The manual driver can provide rotational energy to the main shaft through the transmission mechanism. By operating the manual driver, the transmission mechanism provides torque to the main shaft and stores energy for it, so that the flywheel 5 can rotate continuously for a period of time. The manual driver can be a pull bar 14 with a rack, a pull rope that can be elastically wound around the flywheel 5, a rotating handle for winding the flywheel 5, etc. The transmission mechanism can correspondingly be a gear mechanism, a spring mechanism, a winding mechanism, etc.

[0030] The transmission mechanism is a gear transmission mechanism. The power of the gear transmission mechanism is transmitted to the flywheel 5. The manual driver is a pull bar 14 with a rack formed on one side. A pull bar channel 17 is provided on the movable part. The pull bar 14 can be inserted into the pull bar channel 17. The pull bar 14 in the pull bar channel 17 can mesh and drive with the gears in the gear transmission mechanism. During use, the pull bar 14 is inserted into the pull bar channel 17. The rack on the pull bar 14 meshes with one of the gears in the transmission gear set. When the pull bar 14 is quickly pulled outwards, the rack drives the gear in the gear transmission mechanism to rotate rapidly. It is transmitted to the flywheel 5 through the gear transmission mechanism, causing the flywheel 5 to rotate at a high speed, and then driving the rotating part on the flywheel 5 to rotate at a high speed, realizing the high-speed rotation or rapid walking of the entire rotating system on the ground.

[0031] The gear transmission mechanism includes a main gear 6 fixedly installed coaxially on the flywheel 5, a secondary gear 18 meshing and driving with the main gear 6, and an acceleration gear 19 coaxially fixed to the secondary gear 18. The number of teeth of the acceleration gear 19 is less than that of the secondary gear 18, and the number of teeth of the secondary gear 18 is less than that of the main gear 6. The pull bar 14 meshes and drives with the acceleration gear 19. The rack drives the acceleration gear 19 to rotate by meshing with the acceleration gear 19 with fewer teeth. The acceleration gear 19 and the secondary gear 18 rotate at the same angular velocity. Since the number of teeth of the secondary gear 18 is greater than that of the acceleration gear 19, the secondary gear 18 forms the first acceleration. The secondary gear 18 then meshes with the main gear 6. At this time, since the number of teeth of the main gear 6 is less than that of the secondary gear 18, the second acceleration is formed. Finally, the main shaft rotates at a high speed through two-stage acceleration.

[0032] The main gear 6 has a module of 0.5 and 10 teeth, the secondary gear 18 has a module of 0.5 and 20 teeth, the acceleration gear 19 has a module of 0.7 and 8 teeth, and the pull bar 14 is a rack with a module of 0.7. By meshing the pull bar with the teeth of the acceleration gear with a large module, the strength of the pull bar and the acceleration gear is improved, and it is not easy to be damaged after long-term use. The secondary gear is accelerated by the tooth number difference between the acceleration gear and the secondary gear, and the acceleration is fast. The secondary gear and the main gear are meshed by small-module gears, and further accelerated by the tooth number difference. In addition to adopting this kind of module and tooth number ratio, other module and tooth number ratios can also be used to realize the high-speed rotation of the main gear. This is an equivalent replacement structure that can be easily thought of by those skilled in the art according to this patent and belongs to the protection scope of this patent.

[0033] The flywheel 5 is a metal flywheel 5, and the diameter of the flywheel 5 is 27.8 mm - 35 mm.

[0034] The movable part is a hollow housing structure, and is further provided with a flywheel rotating shaft 4 and a gear mounting disc 7. Both ends of the flywheel rotating shaft 4 are fixedly installed on two opposite inner side walls of the hollow housing. The flywheel 5 is axially stopped and circumferentially rotatable and sleeved outside the flywheel rotating shaft 4. The gear mounting disc 7 is fixedly installed inside the movable part. The gear mounting disc 7 is provided with a central hole 20 and a long-strip gear mounting hole 21. The central hole 20 is for the main gear 6 installed at one axial end of the flywheel 5 to pass through. The long-strip gear mounting hole 21 extends radially along the central hole 20. A long-strip gear mounting groove is further provided on one side wall inside the movable part and is opposite to the position of the gear mounting hole. Both ends of the rotating shaft of the sub-gear 18 are respectively rotatably inserted into the long-strip gear mounting hole 21 and the long-strip gear mounting groove. The movable part can be formed by butting the first plastic shell 1 and the second plastic shell 9, which is convenient for assembly. It is best that the outer sides of both ends of the flywheel rotating shaft 4 are further sleeved with a first fixing ring 2 and a second fixing ring 8. The axial end faces of both ends of the flywheel 5 and the main gear 6 thereon are respectively stopped against the first fixing ring and the second fixing ring, so as to realize the axial stop and positioning of the flywheel 5.
