[0001] This application relates to the field of toy technology, and in particular to a head-spinning device and toy. Background Technology

[0002] In the toy industry, to enhance the fun and appeal of toys, unique actions are often designed for them, such as making the toy suddenly and rapidly turn its head, thereby instantly attracting the player's attention and creating a thrilling and novel experience.

[0003] However, the mechanisms currently available on the market to achieve this effect are either complex in structure, resulting in high production costs and difficult manufacturing processes, which are not conducive to large-scale production; or they have defects in power transmission and motion control, which lead to unstable motion output, making the head-turning motion stiff and jerky, seriously affecting the overall quality of the toy and the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a device and toy that can make rapid head rotation, so as to solve to some extent the technical problems of complex structure, high cost and stiff and stuck head rotation in the prior art.

[0005] This utility model provides a device for rapidly rotating a head, including a housing, a first gear, and a second gear;

[0006] Both the first gear and the second gear are rotatably mounted inside the housing and mesh with each other. The first gear is used to connect to the head of the toy outside the housing, and the second gear is connected to the housing through an elastic element, and a traction rope is connected to the second gear.

[0007] Pulling the traction rope causes the second gear to rotate from the first position to the second position, and releasing the traction rope causes the second gear to rotate from the second position to the first position under the action of the elastic element.

[0008] Furthermore, the housing is also provided with a winding and releasing mechanism, and the end of the traction rope away from the second gear is connected to the winding and releasing mechanism so as to use the winding and releasing mechanism to wind and release the traction rope.

[0009] Furthermore, the winding and releasing mechanism includes a spindle, a drive motor, and a clutch assembly;

[0010] The end of the traction rope away from the second gear is wound around the spindle, and the spindle is connected to the drive end of the drive motor through the clutch assembly;

[0011] When the clutch assembly is engaged, the drive motor can drive the spindle to rotate in order to wind up the traction rope; when the clutch assembly is disengaged, the spindle can rotate freely to release the traction rope.

[0012] Furthermore, the second gear is a sector gear, including a first side portion and a second side portion connected at a predetermined angle, and a sector gear portion connected between the first side portion and the second side portion;

[0013] The housing is provided with a first stop member. When the second gear rotates to the first position, the first side abuts against the first stop member.

[0014] Furthermore, a second stop is provided inside the housing, and the second gear is located between the first stop and the second stop. When the second gear rotates to the second position, the second side abuts against the second stop.

[0015] Furthermore, a limit switch is provided inside the housing, and the second gear is located between the first stop and the limit switch. When the second gear rotates to the second position, the second side triggers the limit switch, and the limit switch is communicatively connected to the winding and releasing mechanism.

[0016] Furthermore, the elastic element is a torsion spring, the spring coil of the torsion spring is sleeved on the rotating shaft of the second gear, one end of the torsion spring is connected to the housing, and the other end of the torsion spring is connected to the first side portion.

[0017] Furthermore, the first side portion extends in a direction away from the axis of rotation of the second gear to form an extension portion, the end of the extension portion away from the axis of rotation of the second gear being a free end, and the free end of the extension portion being connected to the traction rope and the torsion spring.

[0018] Furthermore, a head connector is rotatably connected to the housing. The head connector has a first slot on the side facing the outside of the housing for inserting the head of the toy. The head connector has a second slot on the side facing the inside of the housing.

[0019] The head connector is coaxially arranged with the first gear. A connecting block is provided on the shaft of the first gear. The connecting block can be adapted to be inserted into the second slot, and the cross-section of the second slot is a non-circular structure.

[0020] This utility model also provides a toy, including the head-spinning device described in any of the above claims.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] The head-spinning device provided by this utility model includes a housing, a first gear, a second gear, an elastic element, and a traction rope. The first gear is rotatably disposed inside the housing and can be connected to the head of a toy outside the housing, so that when the first gear rotates around its own axis, it can drive the head of the toy to rotate. The second gear is also rotatably disposed inside the housing and meshes with the first gear. One end of the second gear is connected to the traction rope, and pulling the other end of the traction rope can provide rotational driving force to the second gear through the traction rope, so that the second gear rotates around a first direction (such as clockwise) to rotate from the first position to the second position. At the same time, the second gear is connected to the housing through the elastic element. When the second gear is in the second position and the traction rope is released and can no longer provide rotational driving force to the first gear, the second gear will rotate around a second direction opposite to the first direction (such as counterclockwise) under the action of the elastic force of the elastic element, so as to return from the second position to the first position. When the second gear rotates between the first position and the second position, it can drive the first gear and the toy's head to rotate. When the second gear is in the second position, the toy's head faces the front of the toy. When the second gear is in the first position, the toy's head rotates backward by a predetermined angle.

[0023] In practical use, the second gear is first fixed to the second position using a traction rope, so that the toy's head faces the front of the toy. When it is necessary to turn the toy's head back, the traction rope is released, and the second gear will quickly rotate to the first position under the action of the elastic element, causing the toy's head to suddenly rotate backward by a predetermined angle, thereby achieving the effect of the toy turning its head sharply. Furthermore, this application relies on the gear structure to transmit power and on the elastic force accumulated by the elastic element when the traction rope is released to provide power. This not only has a simple structure and low cost, but also effectively avoids the problems of stiff and jerky head-turning actions, improving the overall quality of the toy and the user experience.

[0024] This utility model also provides a toy that includes the aforementioned head-spinning device, and thus the toy also has the beneficial effects of the head-spinning device. Attached Figure Description

[0036] The following reference Figures 1 to 3 This application describes a head-spinning device and toy according to some embodiments thereof.

[0037] This application provides a device for rapidly rotating a toy, enabling the toy to rotate its head suddenly and quickly. Figures 1 to 3 As shown, the head-spinning device includes a housing 1, a first gear 3, a second gear 2, an elastic element 4, and a traction rope 7. The first gear 3 is rotatably disposed inside the housing 1 and can be connected to the head of a toy outside the housing 1, so that when the first gear 3 rotates around its own axis, it can drive the head of the toy to rotate. The second gear 2 is also rotatably disposed inside the housing 1 and meshes with the first gear 3. The second gear 2 can be driven to rotate, so as to drive the first gear 3 and the head of the toy to rotate. Specifically, the second gear 2 is connected to one end of the traction rope 7. Pulling the other end of the traction rope 7 can provide rotational driving force to the second gear 2 through the traction rope 7, causing the second gear 2 to rotate around a first direction (e.g., counterclockwise) to rotate from the first position to the second position. At the same time, the second gear 2 is connected to the housing 1 through the elastic element 4. When the second gear 2 is in the second position and the traction rope 7 is released and can no longer provide rotational driving force to the first gear 3, the second gear 2 will rotate around a second direction opposite to the first direction (e.g., clockwise) under the action of the elastic force of the elastic element 4 to return from the second position to the first position.

[0038] When the second gear 2 rotates between the first position and the second position, it can drive the first gear 3 and the head of the toy to rotate. When the second gear 2 is in the second position, the head of the toy faces the front of the toy. When the second gear 2 is in the first position, the head of the toy rotates backward by a predetermined angle.

[0039] In practical use, the second gear 2 is first fixed to the second position using the traction rope 7, so that the toy's head faces the front of the toy. When it is necessary to turn the toy's head back, the traction rope 7 is released, and the second gear 2 will quickly rotate to the first position under the action of the elastic element 4, so that the toy's head will suddenly rotate backward by a predetermined angle, thereby achieving the effect of the toy turning its head sharply. Moreover, this application relies on the gear structure to transmit power and relies on the elastic force accumulated by the elastic element 4 when the traction rope 7 is released to provide power. It is not only simple in structure and low in cost, but also effectively avoids the problem of stiff and jerky head-turning action, improving the overall quality of the toy and the user experience.

[0040] In this embodiment, preferably, the angle between the first position and the second position is greater than 90° and less than or equal to 180°.

[0041] In one embodiment of this application, preferably, a winding and releasing mechanism 5 is also provided inside the housing 1. The end of the traction rope 7 away from the second gear 2 is connected to the winding and releasing mechanism 5 so that the winding and releasing mechanism 5 can be used to wind and release the traction rope 7. Specifically, when the winding and releasing mechanism 5 winds the traction rope 7, the length of the traction rope 7 between the winding and releasing mechanism 5 and the second gear 2 becomes shorter, and the traction rope 7 will pull the second gear 2 to rotate, so that the second gear 2 rotates from the first position to the second position. When the winding and releasing mechanism 5 releases the traction rope 7, under the action of the elastic force of the elastic member 4, the traction rope 7 is pulled out of the winding and releasing mechanism 5 so as not to affect the rotation of the second gear 2 from the second position to the first position.

[0042] In this embodiment, preferably, the winding and releasing mechanism 5 includes a spindle 51, a drive motor and a clutch assembly. The end of the traction rope 7 away from the second gear 2 is wound around the spindle 51, and the spindle 51 is connected to the drive end of the drive motor through the clutch assembly.

[0043] The clutch assembly has an engaged state and an disengaged state. When the clutch assembly is engaged, the drive end of the drive motor can act on the spindle 51 to rotate the spindle 51 and wind up the traction rope. When the clutch assembly is disengaged, the spindle 51 can rotate freely to release the traction rope 7 and pull the traction rope 7 outward from the spindle 51.

[0044] Therefore, the clutch assembly enables the drive motor to be connected to the spindle 51, so that the drive motor can drive the spindle 51 to rotate smoothly and the traction rope 7 can be wound up. At the same time, the clutch assembly can quickly disconnect the connection between the spindle 51 and the drive motor to quickly release the traction rope 7.

[0045] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the second gear 2 is a sector gear, comprising a first side portion 21 and a second side portion 22 connected at a predetermined angle, and a sector gear portion connected between the first side portion 21 and the second side portion 22. A first stop is provided inside the housing 1. When the second gear 2 rotates from the second position to the first position, the first side portion 21 abuts against the first stop to limit the second gear 2 to the first position, thereby controlling the toy head's turning angle and preventing it from exceeding a preset angle.

[0046] In this embodiment, preferably, a second stop is also provided inside the housing 1, and the second gear 2 is located between the first stop and the second stop. When the second gear 2 rotates to the second position, the second side 22 can abut against the second stop to limit the second gear 2 to the first position, so that when the second gear 2 is pulled by the traction rope 7 to rotate so that the toy head can be returned to the correct position, the head can be effectively guaranteed to return to the correct position.

[0047] In this embodiment, preferably, a limit switch 6 is also provided inside the housing 1. The second gear 2 is located between the first stop and the limit switch 6. When the second gear 2 rotates to the second position, the second side 22 can trigger the limit switch 6. The limit switch 6 is communicatively connected to the winding and releasing mechanism 5, specifically to the drive motor, to control the start and stop of the drive motor. This allows the drive motor to stop winding the traction rope 7 when the winding and releasing mechanism 5 winds up the traction rope 7 to pull the second gear 2 to the second position.

[0048] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the elastic element 4 is a torsion spring. The spring coil of the torsion spring is sleeved on the rotating shaft of the second gear 2, and one end of the torsion spring is connected to the housing 1, while the other end of the torsion spring is connected to the first side portion 21 (specifically, connected to the extension portion described below), thereby installing the torsion spring between the second gear 2 and the housing 1. When the second gear 2 is in the second position, the torsion spring is compressed, and the elastic force of the torsion spring causes the second gear 2 to have a tendency to rotate from the second position to the first position.

[0049] In this embodiment, preferably, the first side portion 21 extends in a direction away from the axis of rotation of the second gear 2 to form an extension portion. The end of the extension portion away from the axis of rotation of the second gear 2 is the free end of the extension portion. The second gear 2 is connected to the traction rope 7 through the free end of the extension portion. At the same time, the second gear 2 is connected to the torsion spring through the free end of the extension portion, thereby achieving the effect of extending the lever arm by setting the extension portion.

[0050] In one embodiment of this application, preferably, a head connector 11 is rotatably connected to the housing 1, and the head connector 11 is coaxially arranged with the first gear 3; one end of the head connector 11 faces the outer shell of the housing 1 and forms a first slot, which is used to insert the head of the toy; the other end of the head connector 11 extends into the interior of the housing 1 and forms a second slot, and the shaft of the first gear 3 is provided with a connecting hole, which can be fitted into the second slot, and the cross-section of the second slot is a non-circular structure, so that the head of the toy is connected to the first gear 3 through the head connector 11, so that the first gear 3 can drive the head of the toy to rotate when it rotates.

[0051] This application also provides a toy including the head-spinning device of any of the above embodiments.

[0052] In this embodiment, the toy includes a head-spinning device, and therefore the toy has all the beneficial effects of the head-spinning device, which will not be described in detail here.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
