Description
Technical Field
[0001] This application relates to the field of toy technology, and in particular to a continuous rotating head device and toy. Background Technology
[0002] In the toy industry, in order to enhance the fun and interactivity of toys, it is often necessary to give toys a variety of actions and functions. For example, the toy's head can rotate continuously to increase the toy's vividness and fun.
[0003] Existing toys with rotating heads typically simply have a motor inside the toy to drive the head to rotate. However, this method results in a limited range of rotation speeds and patterns, making it difficult to meet consumers' demands for dynamic effects in toys. This leads to low entertainment value and is insufficient in attracting the attention of consumers, especially children. Utility Model Content
[0004] The purpose of this invention is to provide a continuous head-rotating device and toy, so as to enrich the dynamic effect of the toy's head rotation to a certain extent and improve the toy's fun and appeal.
[0005] This utility model provides a continuous rotating head device, including a driving gear, an intermediate gear, and a driven gear with parallel rotating shafts;
[0006] The driven gear is used to connect to the head of the toy;
[0007] The drive gear can be driven to perform periodic non-uniform reciprocating rotation between a first position and a second position spaced at a predetermined angle.
[0008] The intermediate gear is disposed between the driving gear and the driven gear. The intermediate gear meshes with the driving gear and can roll around the driving gear so that it can be pushed by the driving gear to mesh with the driven gear, or pushed by the driven gear to separate from the driven gear.
[0009] Furthermore, the continuous rotating head device also includes a rotatably mounted cam, which is capable of continuously rotating around its own axis in a predetermined direction;
[0010] The drive gear is provided with a prying part. During one rotation cycle of the cam, the cam can first contact and then disengage from the prying part. When the cam contacts the prying part, the cam can act on the pushing part to make the drive gear rotate.
[0011] Furthermore, the cam has a curved surface that can contact the actuating part, the curved surface having a first curved surface with a gradually increasing radius, so that during the contact between the first curved surface and the actuating part, the driving gear can be driven to rotate from the first position to the second position.
[0012] Furthermore, the curved surface has a second curved surface, and the first curved surface and the second curved surface are sequentially connected along the rotation direction of the cam;
[0013] The radius of the second curved surface is gradually decreasing, so that when the second curved surface comes into contact with the actuating part, it can drive the drive gear to rotate from the second position to the third position, the third position being located between the first position and the second position.
[0014] Furthermore, the continuous rotating head device is disposed inside the housing, and the continuous rotating head device also includes an elastic element, one end of which abuts against the housing, and the other end of which abuts against the drive gear;
[0015] The elastic force of the elastic element causes the drive gear to have a tendency to rotate from the second position to the first position.
[0016] Furthermore, the driving gear is a sector gear, and the straight edge of one side of the sector gear is the driving straight edge, and the actuating part is disposed on the driving straight edge.
[0017] Furthermore, the elastic element is a torsion spring, the spring coil of which is sleeved on the rotating shaft of the drive gear. One end of the torsion spring is connected to the housing, and the other end of the torsion spring is connected to the end of the rotating shaft of the drive straight edge that is away from the sector gear.
[0018] Furthermore, the housing is provided with an arc-shaped limiting groove, which surrounds the drive gear with a predetermined arc.
[0019] The shaft of the intermediate gear is adapted to be installed in the arc-shaped limiting groove, so that the intermediate gear can rotate around its own axis and can roll around the driving gear.
[0020] Furthermore, the continuous rotating head device also includes a drive mechanism, the drive end of which is connected to the rotating shaft of the cam to drive the cam to rotate continuously around a predetermined direction.
[0021] This utility model also provides a toy, including the continuous rotating head device described in any of the above claims.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0023] The continuous rotating head device provided by this utility model includes a drive assembly, a driving gear, an intermediate gear, and a driven gear. The driven gear is used to connect to the toy's head, so that the rotation of the driven gear drives the toy's head to rotate. The driving gear is located on one side of the driven gear in the radial direction. The driving gear can perform non-uniform periodic reciprocating intermittent rotation under the drive assembly. That is, the driving gear can rotate from a first position to a second position and then back to the first position in one rotation cycle, and then enter the next rotation cycle after stopping for a predetermined time. The driving gear is non-uniform in its rotation. The intermediate gear is movably configured so that it can roll around the driving gear while maintaining engagement with it, until it engages with or disengages from the driven gear. The driving force for the driven gear to roll is provided by the driving gear or driven gear that is engaged and rotating with it. Therefore, through the non-uniform periodic reciprocating intermittent rotation of the driving gear and the transmission of the intermediate gear, the driven gear can drive the toy's head to perform periodic non-uniform continuous rotation, thereby enriching the dynamic effect of the continuous rotation of the toy's head to a certain extent and improving the toy's fun and attractiveness.
[0024] This utility model also provides a toy that includes the aforementioned continuous head-rotating device, and thus the toy also has the beneficial effects of the continuous head-rotating device. Attached Figure Description

[0034] The following reference Figure 1 This application describes a continuous rotating head device and toy according to some embodiments thereof.
[0035] This application provides a continuous head-rotating device for use inside a toy to drive the toy's head to rotate.
[0036] like Figure 1 As shown, the continuous rotating head device includes a drive assembly, a drive gear 1, an intermediate gear 2, and a driven gear 3. The driven gear 3 is used to connect to the head of the toy so that the rotation of the driven gear 3 drives the head of the toy to rotate. The drive gear 1 is located on one side of the driven gear 3 in the radial direction, and the drive gear 1 can perform non-uniform periodic reciprocating intermittent rotation under the drive of the drive assembly. That is, the drive gear 1 can rotate from a first position to a second position in one rotation cycle, and then return to the first position. After stopping the rotation for a predetermined time, it enters the next rotation cycle. The drive gear 1 is non-uniform in the rotation process.
[0037] The intermediate gear 2 is located between the driving gear 1 and the driven gear 3. The intermediate gear 2 meshes with the driving gear 1 and is movably arranged so that the intermediate gear 2 can roll around the driving gear 1 while maintaining meshing with the driving gear 1, so as to roll until it meshes with the driven gear 3 or separates from the driven gear 3.
[0038] In this embodiment, the driving force that causes the driven gear 3 to roll is provided by the driving gear 1 or the driven gear 3 that meshes with and rotates with it.
[0039] Specifically, such as Figure 1 The relative positions of the driving gear 1, intermediate gear 2, and driven gear 3 are shown. In one rotation cycle of the driving gear 1, the driving gear 1 can first rotate counterclockwise from the first position to the second position, and then rotate clockwise from the second position to the first position and stay for a predetermined time to enter the next rotation cycle. Before the rotation begins, the driving gear 1 is in the first position, the intermediate gear 2 is meshed with the driving gear 1 and separated from the driven gear 3. As the driving gear 1 rotates counterclockwise from the first position to the second position, the intermediate gear 2 will rotate clockwise under the action of the driving gear 1. At the same time, due to the tangential force between the driving gear 1 and the intermediate gear 2, the intermediate gear 2 will roll counterclockwise around the driving gear 1, that is, roll upward to move away from the driven gear 3.
[0040] Then, the driving gear 1 rotates clockwise from the second position to the first position. During this process, the driving gear 1 will pass through the third position, which is located between the second position and the first position. While the driving gear 1 rotates clockwise from the second position to the third position, the intermediate gear 2 rotates counterclockwise and rolls clockwise around the driving gear 1 until it meshes with the driven gear 3. After the intermediate gear 2 meshes with the driven gear 3, the driving gear 1 continues to rotate from the third position to the first position. At this time, the intermediate gear 2 can only rotate on its own between the driving gear 1 and the driven gear 3 and cannot roll. Through the transmission of the intermediate gear 2, the driven gear 3 will rotate clockwise to drive the toy head to rotate clockwise.
[0041] When the driving gear 1 reaches the first position, it will stop rotating and remain there for a predetermined time. During this time, the driven gear 3 will continue to rotate clockwise due to the inertia of the toy head. Meanwhile, since the driving gear 1 has stopped rotating, the intermediate gear 2 will roll counterclockwise (upwards) around the driving gear 1 under the tangential force between itself and the driven gear 3, thus separating from the driven gear 3 and preventing it from affecting the continued rotation of the driven gear 3 and the toy head under inertia. This process continues until the next rotation cycle of the driving gear 1 begins, repeating the above motion. Thus, through the non-uniform, periodic, intermittent rotation of the driving gear 1 and the transmission of the intermediate gear 2, the driven gear 3 can drive the toy head to perform periodic, non-uniform, continuous rotation, thereby enriching the dynamic effect of the toy head's continuous rotation and enhancing the toy's fun and appeal.
[0042] In one embodiment of this application, preferably, the driving component includes a cam 4, which is disposed on one side of the drive gear 1. The cam 4 is capable of rotating continuously around its own axis in a predetermined direction (such as clockwise). The drive gear 1 is provided with a toggle part 11. During the rotation of the cam 4 one revolution (i.e., 360°), the cam 4 can first contact and then disengage from the toggle part 11. During the contact between the cam 4 and the toggle part 11, the cam 4 can provide driving force to the toggle part 11, causing the drive gear 1 to rotate.
[0043] It should be noted that one rotation of cam 4 corresponds to one rotation cycle of drive gear 1, that is, as mentioned above, drive gear 1 rotates from the first position to the second position, and then rotates from the second position to the third position and back to the first position.
[0044] Preferably, the cam 4 has a curved surface that can abut against the actuating part 11. The curved surface includes a first curved surface. As the cam 4 rotates, the first curved surface first contacts the actuating part 11, and the radius of the first curved surface gradually increases along the rotation direction of the cam 4. During the process of the first curved surface contacting the actuating part 11, the first curved surface can push the driving gear 1 to rotate, causing the driving gear 1 to rotate from the first position to the second position, and through the driving gear 1, drive the intermediate gear 2 to roll away from the driven gear 3.
[0045] Preferably, the curved surface further includes a second curved surface, which is sequentially connected to the first curved surface along the rotation direction of the cam 4. That is, as the cam 4 rotates, the actuating part 11 of the drive gear 1 will transition from contact with the first curved surface to contact with the second curved surface.
[0046] The radius of the second curved surface gradually decreases along the rotation direction of the cam 4. At the same time, the drive assembly also includes an elastic element 5, which causes the drive gear 1 to have a tendency to rotate from the second position to the first position. Thus, when the cam 4 contacts the actuating part 11 through the second curved surface, under the drive of the elastic element 5, the actuating part 11 of the cam 4 can maintain contact with the second curved surface and rotate from the second position to the first position to the third position between the first and second positions. During this process, the intermediate gear 2 will roll under the action of the tangential force between it and the drive gear 1 until it meshes with the driven gear 3.
[0047] Then, as the cam 4 continues to rotate, the cam 4 will disengage from the actuating part 11, causing the driving gear 1 to rotate from the third position to the first position under the action of the elastic member 5, until the cam 4 re-enters contact with the actuating part 11 through the first curved surface, and the driving gear 1 will enter the next rotation cycle; during the process of the driving gear 1 rotating from the third position to the first position, through the transmission of the intermediate gear 2, the driving gear 1 will drive the driven gear 3 and the head of the toy to rotate.
[0048] After the drive gear 1 returns to the first position under the action of the elastic element 5, it will remain stationary before it re-contacts the first curved surface of the cam 4. At this time, as mentioned above, due to the inertia of the toy head, the toy head and the driven gear 3 will continue to rotate, and the tangential force between the driven gear 3 and the intermediate gear 2 will push the intermediate gear 2 to roll around the drive gear 1 in a direction away from the driven gear 3, causing the intermediate gear 2 to disengage from the driven gear 3.
[0049] It should be noted that before the intermediate gear 2 meshes with the driven gear 3 again, the driven gear 3 may have stopped rotating or it may still be rotating.
[0050] Regarding the arrangement of the elastic element 5, in this embodiment, preferably, the continuous rotating head device of this application is disposed inside the housing, one end of the elastic element 5 is connected to the housing, and the other end of the elastic element 5 is connected to the drive gear 1. Specifically, the drive gear 1 is a sector gear, and the straight edge of one side of the sector gear is the driving straight edge, on which the aforementioned actuating part 11 is disposed. The elastic element 5 is a torsion spring, the spring coil of the torsion spring is sleeved on the rotating shaft of the sector gear, one end of the torsion spring is connected to the housing, and the other end of the torsion spring is connected to the driving straight edge, specifically to the end of the driving straight edge that is away from the rotating shaft of the sector gear.
[0051] Regarding the setting of the intermediate gear 2, in this embodiment, preferably, the housing is provided with an arc-shaped limiting groove. The arc-shaped limiting groove surrounds the driving gear 1 with a predetermined arc. The rotating shaft of the intermediate gear 2 is adapted to be installed in the arc-shaped limiting groove, so that the intermediate gear 2 can rotate around its own axis and can roll along the extension direction of the arc-shaped limiting groove to mesh with or disengage from the driven gear 3.
[0052] In one embodiment of this application, preferably, the continuous rotating head device further includes a drive mechanism, the drive end of which is connected to the rotating shaft of the cam 4 to drive the cam 4 to rotate continuously around a predetermined direction.
[0053] This application also provides a toy including the continuous rotating head device of any of the above embodiments.
[0054] In this embodiment, the toy includes a continuous rotating head device, and therefore the toy has all the beneficial effects of a continuous rotating head device, which will not be described in detail here.
[0055] 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.
