Toys are tools for intellectual development and entertainment. With the continuous improvement of people's living standards, users' pursuit of the quality and functionality of toys is also getting higher and higher. Among them, projectile toys based on spinning tops have attracted a large number of fans and users due to animation movies and their unique gameplay.

However, existing projectile toys usually use rack acceleration to accelerate and rotate the spinning top. Specifically, a rack first passes through a driving gear, and then the rack is pulled to drive the driving gear to rotate, and then the driving gear drives the spinning top to rotate and accelerate. This kind of driving device of the spinning top is typically capable of performing a one-time acceleration. After the rack is pulled out, it cannot be accelerated twice, causing the spinning top to be unable to obtain more rotational potential energy. In addition, a user must use both hands to operate through a driving method of the rack acceleration. This makes driving and acceleration of the spinning top cumbersome, time-consuming and labor-intensive, and reduces the fun of the spinning top.

Embodiment 1

This embodiment provides a driving device 100, which includes a case 10 and an acceleration gear set 20. The acceleration gear set 20 is rotatably provided in the case 10, and a gravity block 30 is slidably provided on the case 10. The gravity block 30 is drivingly connected to the acceleration gear set 20; when the gravity block 30 slides back and forth on the case 10 by swinging, the gravity block 30 drives the acceleration gear set 20 to rotate.

Specifically, the acceleration gear set 20 is rotatably disposed inside the case 10, a first opening is provided on one side of the case 10, and at least a portion of the acceleration gear set 20 extends out of the first opening of the case 10; a first driving rack 31 is provided on one side of the gravity block 30, and the first driving rack 31 is cooperatively and drivingly connected with the portion of the acceleration gear set 20 extending out of the first opening of the case 10.

In order to ensure that an output end of the acceleration gear set 20 is able to rotate in one direction when the gravity block 30 slides back and forth on the case 10, the acceleration gear set 20 in this embodiment includes a first active gear 21, a first clutch gear 22 and a driving gear 23. The case 10 is provided with a first arc-shaped groove 11. The first active gear 21 and the driving gear 23 are respectively rotatably provided in the case 10, and the first active gear 21 meshes with the first clutch gear 22. The first clutch gear 22 is slidably disposed in the first arc-shaped groove 11. When the first clutch gear 22 slides to one end of the first arc-shaped groove 11, the first clutch gear 22 meshes with the driving gear 23. When the first clutch gear 22 slides to other positions of the first arc-shaped groove 11, the first clutch gear 22 and the driving gear 23 do not contact each other.

Further, at least a portion of the first active gear 21 extends out of the first opening of the case 10, and the portion of the first active gear 21 extending out of the first opening is cooperatively and drivingly connected with the first driving rack 31 of the gravity block 30. Wherein, in order to enable the gravity block 30 to better drive the first active gear 21 when sliding back and forth, the first opening of this embodiment is provided in the middle of one side of the case 10, and a length of the first driving rack 31 is slightly longer than half a length of one side of the case 10. In this way, when the gravity block 30 slides back and forth, since the first opening is located in the middle of one side of the case 10 and the length of the first driving rack 31 is just longer than half the length of one side of the case 10, the first driving rack 31 always meshes with and is connected to the first active gear 21. Moreover, a travel distance of the first driving rack 31 in back and force sliding that may drive the first active gear 21 to rotate is half the length of one side of the case 10, thereby allowing that the gravity block 30 may better drive the first active gear 21.

It should be noted that in this embodiment the first opening is not limited to being located in the middle of one side of the case 10. It may also be located in other positions on one side of the case 10. Correspondingly, the length of the first driving rack 31 is not limited to the above length, and other lengths of the driving rack may also be used.

Therefore, the acceleration gear set 20 of this embodiment is provided with a slidable first clutch gear 22, and a first arc-shaped groove 11 matching the first clutch gear 22 is provided on the case 10, allowing that a rotating shaft of the first clutch gear 22 may slide in the first arc-shaped groove 11. In addition, the first active gear 21 of this embodiment always meshes with the first clutch gear 22, when the gravity block 30 slides along a left direction, the first driving rack 31 drives the first active gear 21 to rotate clockwise. At the same time, the first active gear 21 drives the first clutch gear 22 to rotate counterclockwise. At this time, the first clutch gear 22 slides to one end of the first arc-shaped groove 11 close to the driving gear 23 under a pushing action of the first active gear 21, and meshes with and is connected with the driving gear 23. At the same time, due to the pushing action of the first active gear 21, the first clutch gear 22 always meshes with the driving gear 23. That is to say, when the gravity block 30 slides to the left, the first driving rack 31 drives the first active gear 21, the first clutch gear 22 and the driving gear 23 to rotate in sequence.

When the gravity block 30 slides along a right direction, the first driving rack 31 drives the first active gear 21 to rotate counterclockwise, and at the same time the first active gear 21 drives the first clutch gear 22 to rotate clockwise. At this time, the first clutch gear 22 slides to one end of the first arc-shaped groove 11 away from the driving gear 23 under the pushing action of the first active gear 21, and is not in contact with the driving gear 23. Due to the pushing action of the first active gear 21, the first clutch gear 22 remains disengaged from the driving gear 23 at all times. Thetis to say, when the gravity block 30 slides to the right, the first driving rack 31 drives the first active gear 21 and the first clutch gear 22, and the driving gear 23 continues to rotate in its original direction since it is disengaged from the first clutch gear 22.

Therefore, in this embodiment, a position of the first arc-shaped groove 11 is cleverly set, and when the first clutch gear 22 moves to one end of the first arc-shaped groove 11, the first clutch gear 22 meshes with the driving gear 23. When the first clutch gear 22 slides to other positions of the first arc-shaped groove 11, the first clutch gear 22 and the driving gear 23 do not contact each other, so that a rotation direction of the driving gear 23 is kept unchanged through a back and forth sliding motion of the gravity block 30.

In addition, in the acceleration gear set 20 of this embodiment, one or more first driven gears 26 are drivingly connected between the first active gear 21 and the first clutch gear 22.

In some embodiments, first protrusions 14 are respectively provided at both ends of the side of the case 10 provided with the first opening, and a guide slide rod 13 is provided between the two first protrusions 14. The gravity block 30 is slidable sleeved on the guide slide rod 13 of the case 10. In this embodiment, a first guide seat 34 is provided between the first driving rack 31 of the gravity block 30 and the gravity block 30. The first guide seat 34 is provided with a first guide hole which is slidably sleeved on the guide slide rod 13.

Therefore, in the case 10 of this embodiment, by providing the two first protrusions 14, which may serve as an installation structure for the guide slide rod 13, and may also serve as a limiting structure for the first driving rack 31, it may effectively prevent the first driving rack 31 from sliding out of the guide slide rod 13, making a reciprocating sliding of the gravity block 30 safe and effective.

In order to make the gravity block 30 slide more smoothly, in this embodiment, one or more sliding wheels 33 are provided at the bottom of the gravity block 30, and the gravity block 30 is slidably disposed on an upper surface of the case 10 through the one or more sliding wheels 33. In this way, a surface-to-surface contact friction between the gravity block 30 and the case 10 is avoided, making a sliding movement of the gravity block 30 relative to the case 10 smoother.

In order to further ensure smooth and stable sliding of the gravity block 30, the other side of the case 10 in this embodiment is also provided with the guide slide rod 13, and the guide slide rods 13 on both sides of the case 10 are parallel to each other. Correspondingly, second protrusions 15 are respectively provided at both ends of the other side of the case 10. The guide slide rod 13 is provided between the two second protrusions 15, and a second guide seat 35 is provided at the bottom of the other side of the gravity block 30. The second guide seat 35 is provided with a second guide hole. In this way, both sides of the gravity block 30 are slidably sleeved on the guide slide rods 13 on both sides of the case 10 through the first guide hole and the second guide hole respectively. Combined with one or more sliding wheels 33 at the bottom of the gravity block 30, a sliding of the gravity block 30 relative to the case 10 is more stable and smooth, which is also beneficial to a meshing drive between the first driving rack 31 of the gravity block 30 and the acceleration gear set 20.

In this embodiment, the first guide seat 34 is integrally formed with the first driving rack 31, the second guide seat 35 is integrally formed with the second driving rack 32, and the first guide seat 34 and the second guide seat 35 are respectively provided at the middle position on both sides of the bottom of the gravity block 30.

Compared with the conventional art, the driving device 100 of this application swings the gravity block 30 back and forth, so that the gravity block 30 continuously accelerates and rotates the acceleration gear set 20. Particularly, the acceleration gear set 20 is driven and accelerated through the first driving rack 31 on one side of the gravity block 30, and the first clutch gear 22 in the acceleration gear set 20 ensures the one-way rotation of the driving gear 23, thus avoiding a bidirectional rotation of the driving gear 23 due to the back and forth swing of the gravity block 30. As a result, the driving gear 23 always maintains the one-way rotation. Therefore, the driving device 100 of the present application is easy to operate, has a novel and interesting driving method, expands the functionality and fun of the driving device 100, and has high marketing value.

Embodiment 2

This embodiment is substantially the same as Embodiment 1. The difference is that in this embodiment, a second opening is provided on the other side of the case 10, and a second driving rack 32 is provided on the other side of the gravity block 30; the acceleration gear set 20 also includes a second active gear 24 and a second clutch gear 25; the case 10 is provided with a second arc-shaped groove 12; the second clutch gear 25 is slidably disposed in the second arc-shaped groove 12, and the second clutch gear 25 meshes with the second active gear 24; when the second clutch gear 25 slides to one end of the second arc-shaped groove 12, the second clutch gear 25 meshes with the driving gear 23; when the second clutch gear 25 slides to other positions of the second arc-shaped groove 12, the second clutch gear 25 and the driving gear 23 do not contact each other.

In this embodiment, at least a portion of the second active gear 24 extends out of the second opening of the case 10, and the portion of the second active gear 24 extending out of the second opening is cooperatively and drivingly connected with the second driving rack 32 of the gravity block 30. The second active gear 24, the second clutch gear 25 and the second arc-shaped groove 12 are respectively arranged symmetrically with the first active gear 21, the first clutch gear 22 and the first arc-shaped groove 11 with respect to the driving gear 23.

That is to say, compared with Embodiment 1, the case 10 of this embodiment is further provided with the second opening and the second arc-shaped groove 12, and the second opening is provided in the middle of the other side of the case 10. The second arc-shaped groove 12 and the first arc-shaped groove 11 are arranged symmetrically with respect to the driving gear 23; and the acceleration gear set 20 of this embodiment is further provided with the second active gear 24 and the second clutch gear 25, and the second active gear 24 and the second clutch gear 25 are arranged symmetrically with the first active gear 21 and the first clutch gear 22 in Embodiment 1 with respect to the driving gear 23; correspondingly, the other side of the gravity block 30 is provided with the second driving rack 32, the second guide seat 35 is provided between the second driving rack 32 and the gravity block 30, and the second driving rack 32 and the first driving rack 31 are arranged symmetrically with respect to the case 10.

Therefore, when the gravity block 30 of this embodiment slides along the left direction, the first driving rack 31 drives the first active gear 21 to rotate clockwise, and at the same time, the first active gear 21 drives the first clutch gear 22 to rotate counterclockwise. At this time, the first clutch gear 22 slides to one end of the first arc-shaped groove 11 close to the driving gear 23 under pushing action of the first active gear 21 and meshes with the driving gear 23. At the same time, due to the pushing action of the first active gear 21, the first clutch gear 22 always meshes with the driving gear 23. The second driving rack 32 drives the second active gear 24 to rotate counterclockwise, and at the same time the second active gear 24 drives the second clutch gear 25 to rotate clockwise. At this time, the second clutch gear 25 slides to one end of the second arc-shaped groove 12 away from the driving gear 23 and is not in contact with the driving gear 23 under pushing action of the second active gear 24, and due to the pushing action of the second active gear 24, the second clutch gear 25 remains disengaged from the driving gear 23 at all times.

That is to say, when the gravity block 30 drives the first driving rack 31 and the second driving rack 32 to slide to the left, the first driving rack 31 drives the driving gear 23 to rotate, and due to the second clutch gear 25 and the driving gear 23 are not in contact with each other, and the second clutch gear 25 is idling so that the second driving rack 32 does not drive the driving gear 23 to rotate.

When the gravity block 30 slides along the right direction, the first driving rack 31 drives the first active gear 21 to rotate counterclockwise, and at the same time the first active gear 21 drives the first clutch gear 22 to rotate clockwise. At this time, the first clutch gear 22 slides to one end of the first arc-shaped groove 11 away from the driving gear 23 and is not in contact with the driving gear 23 under pushing action of the first active gear 21. Due to the pushing action of the first active gear 21, the first clutch gear 22 remains disengaged from the driving gear 23 at all times. The second driving rack 32 drives the second active gear 24 to rotate clockwise, and at the same time the second active gear 24 drives the second clutch gear 25 to rotate counterclockwise. At this time, the second clutch gear 25 slides to one end of the second arc-shaped groove 12 close to the driving gear 23 and meshes with the driving gear 23 under pushing action of the second active gear 24. Due to the pushing action of the second active gear 24, the second clutch gear 25 always meshes with the driving gear 23, thereby allowing the second driving rack 32 to drive the second active gear 24, the second clutch gear 25 and the driving gear 23 to rotate in sequence.

That is to say, when the gravity block 30 drives the first driving rack 31 and the second driving rack 32 to slide to the right, since the first clutch gear 22 and the driving gear 23 are in a separated state, the first driving rack 31 drives the first active gear 21 and the first clutch gear 22 to idle. The second driving rack 32 drives the second active gear 24, the second clutch gear 25 and the driving gear 23 to rotate in sequence, and causes the driving gear 23 to continue to rotate in the original direction. Moreover, driven by the second driving rack 32, the second active gear 24 continues to drive the driving gear 23 to rotate through the second clutch gear 25, so that the gravity block 30 always drives the driving gear 23 in a single direction and stores energy during the reciprocating sliding process.

Therefore, in this embodiment, the first active gear 21, the first clutch gear 22, the first arc-shaped groove 11 are arranged symmetrically respectively with the second active gear 24, the second clutch gear 25, and the second arc-shaped groove 12 with respect to the driving gear 23, and the first driving rack 31 and the second driving rack 32 of the gravity block 30 are arranged symmetrically with respect to the case 10, so that when the gravity block 30 slides back and forth, the driving gear 23 always keeps the rotation direction unchanged.

Furthermore, one or more second driven gears 27 are drivingly connected between the second active gear 24 and the second clutch gear 25 in this embodiment. In addition, the driving gear 23 in this embodiment adopts a dual-layer gear structure. In this way, the output end of the driving gear 23 in this embodiment may also be drivingly connected to one or more output gears 28.

Compared with the conventional art, the driving device 100 of this embodiment swings the gravity block 30 back and forth, so that the gravity block 30 continuously accelerates and rotates the acceleration gear set 20. Particularly, the acceleration gear set 20 is driven and accelerated through the driving racks on both sides of the gravity block 30, and the two clutch gears in the acceleration gear set 20 ensures the one-way rotation of the driving gear 23, thus avoiding a bidirectional rotation of the driving gear 23 due to the back and forth swing of the gravity block 30. As a result, the driving gear 23 always maintains the one-way rotation. Therefore, the driving device 100 of the present application is easy to operate, has a novel and interesting driving method, expands the functionality and fun of the driving device 100, and has high marketing value.

Embodiment 3

This embodiment provides a spinning top accelerator, which includes the driving device 100 according to any one of the above embodiments. The spinning top accelerator further includes a clamping assembly 40 used for clamping the spinning top and an injection pushing assembly 50 used for ejecting the spinning top, and the clamping assembly 40 is drivingly connected with the driving device 100.

In this embodiment, the spinning top accelerator includes a housing 200 with upper and lower openings. The case 10 of the driving device 100 is fixed inside the housing 200. The clamping assembly 40 includes a transmission gearbox 41 and a magnetic sleeve 42. The transmission gearbox 41 is fixed below the case 10 of the driving device 100, and the bottom of the case 10 is provided with a through hole. The transmission gearbox 41 is rotatably provided with a passive gear 43. The passive gear 43 meshes and is connected to the driving gear 23 of the driving device 100. The magnetic sleeve 42 is arranged below the transmission gearbox 41, and the magnetic sleeve 42 is coaxially fixedly connected with the passive gear 43. Therefore, the magnetic sleeve 42 of this embodiment is used to clamp the spinning top.

Further, in this embodiment, the magnetic sleeve 42 has a cylindrical structure with an open lower end, and a magnetic unit 44 is provided on the top of an inner wall of the magnetic sleeve 42. In this way, the magnetic unit 44 in the magnetic sleeve 42 may be used to attract the spinning top with a magnet unit on the top and fix the spinning top by attraction. Therefore, the spinning top accelerator of this embodiment may drive the passive gear 43 to rotate through the driving gear 23 of the driving device 100, and at the same time drive the magnetic sleeve 42 to rotate, and then drive the spinning top clamped in the magnetic sleeve 42 through the magnetic sleeve 42 to rotate and store energy.

In addition, the injection pushing assembly 50 of this embodiment includes an injection pushing rod 51 and a return spring 52. An upper end of the injection pushing rod 51 is located at an upper opening of the housing 200, a middle part of the injection pushing rod 51 is connected to an inner wall of the housing 200 through the return spring 52, and a lower end of the injection pushing rod 51 is located on an outer peripheral side of the magnetic sleeve 42. Therefore, by pressing the upper end of the injection pushing rod 51 downward, the injection pushing rod 51 moves downward and compresses the return spring 52. At the same time, the lower end of the injection pushing rod 51 moves downward quickly and may quickly push the spinning top in the magnetic sleeve 42 out from the lower opening of the housing 200; after loosening the upper end of the injection pushing rod 51, the injection pushing rod 51 quickly moves up and resets under an action of the return spring 52.

In this embodiment, the driving device 100 is operated by a user holding the housing 200 of the spinning top accelerator and rocking it left and right. Under the action of inertia, the gravity block 30 keeps sliding left and right along with the housing 200 to perform a reciprocating motion, and at the same time drives the acceleration gear set 20 to rotate, so that the driving gear 23 of the acceleration gear set 20 drives the passive gear 43 to rotate, and finally drives the spinning top in the magnetic sleeve 42 to rotate and store energy. After storing energy, the spinning top may be ejected out through the injection pushing rod 51.

In some embodiments, one or more third driven gears 45 may be disposed between the passive gear 43 and the driving gear 23. In order to clearly distinguish a rocking direction of the gravity block 30, recessed portions 201 are provided on both sides of the housing 200 in this embodiment, and a connection line of the two recessed portions 201 is parallel to a sliding direction of the gravity block 30. In this way, the user may distinguish the rocking direction of the gravity block 30 by holding the two recessed portions 201.

Therefore, the spinning top accelerator of this application uses a rocking method to drive and store energy on the driving device 100, and then drive the clamping assembly 40 to rotate through the driving device 100. At the same time, the clamping assembly 40 may drive the spinning top to rotate and store energy, and the spinning top after rotation and energy storing is ejected out through the injection pushing assembly 50. Therefore, the spinning top accelerator of the present application is easy to operate, has a novel and interesting driving method, expands the functionality and fun of the spinning top accelerator, and has high marketing value.

Although the present invention has been disclosed in the form of preferred embodiments and variations thereon, it will be understood that numerous additional modifications and variations could be made thereto without departing from the scope of the invention.

For the sake of clarity, it is to be understood that the use of “a” or “an” throughout this application does not exclude a plurality, and “comprising” does not exclude other steps or elements.
