Description

Technical Field

[0001] This invention relates to the field of toy technology, specifically to a toy, a building block linkage mechanism, and a linkage method thereof. Background Technology

[0002] Transforming toys, a popular category in the toy industry, rely on the core playability of the coordinated and smooth movements of the limbs during transformation. Currently, most transforming building block toys on the market have limited designs that link the leg joints with auxiliary parts (such as wheels), resulting in monotonous transformation forms and insufficient interactivity, failing to meet consumers' demands for highly realistic and strongly coordinated transformation effects.

[0003] In existing transforming toy technology, only some products involve the linkage function between legs and wheels, such as... Figure 5 As shown, the existing technology uses a structure of multiple independent gears connected in series. Its transmission logic is "deceleration first, then acceleration." However, limited by the meshing characteristics of the gear sets, the actual rotation angle of the lower leg wheel can only reach about 30 degrees, exhibiting significant technical defects: on the one hand, the deceleration and acceleration conversion of the multi-stage gears leads to large power transmission losses and slow linkage response; on the other hand, the limited wheel rotation angle prevents the achievement of a complete rotation stroke, making it difficult to simulate the wheel state of a real vehicle and limiting the diversity and precision of deformation movements. Therefore, developing a leg linkage transmission structure with precise linkage and adaptability to modular assembly has become an urgent technical problem to be solved in this field. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of this invention is to provide a toy, a building block linkage mechanism and a linkage method thereof.

[0005] According to the present invention, a modular linkage mechanism is capable of switching between an initial state and a maximum bending state, comprising a first part, a second part, a third part, a rotating body, and a transmission assembly; In the initial state, when the first part is driven to rotate by a first angle, the second part can be triggered to rotate together with the first part, and after the two rotate together by a second angle, the transmission component can be triggered to drive the rotating body to rotate.

[0006] A bending linkage method for a building block linkage mechanism according to the present invention includes the following steps: S1: In the initial state, driving the first part to rotate at a first angle and then continuing to rotate can trigger the second part to rotate synchronously with the first part; S2: Driving the first part and the second part to rotate at a second angle and then continuing to rotate can trigger the transmission component to drive the rotating body to rotate and switch to the maximum bending state.

[0007] The extension linkage method of the building block linkage mechanism provided by the present invention includes the following steps: M1: When the block linkage mechanism is in the maximum bending state, driving the first part to rotate in the opposite direction by a first angle and then continuing to rotate can trigger the second part to rotate in the opposite direction synchronously with the first part. M2: Driving the first part and the second part to rotate in opposite directions by a second angle and then continuing to rotate in opposite directions can trigger the transmission component to drive the rotating body to rotate in opposite directions and switch back to the initial state.

[0008] Preferably, the first part is rotatably supported on the first shaft of the second part, the second part is rotatably supported on the second shaft of the third part, and the second part is drivenly connected to the rotating body through the transmission assembly.

[0009] Preferably, the first part is provided with a first arc-shaped hole, and the second part is provided with a first limiting head whose end extends into the first arc-shaped hole; in the initial state, when the first arc-shaped hole rotates to abut against the first limiting head and continues to rotate, the second part is triggered to rotate around the second axis.

[0010] Preferably, the second part is provided with a second arc-shaped hole, and the transmission component includes a connecting rod. One end of the connecting rod is provided with a second limiting head that extends into the second arc-shaped hole. When the second arc-shaped hole rotates to abut against the second limiting head and continues to rotate, the connecting rod is triggered to pull the rotating body to rotate in the opposite direction.

[0011] Preferably, the second rotating shaft is arranged between the first rotating shaft and the second arc-shaped hole.

[0012] Preferably, the transmission component is a gear transmission component.

[0013] Preferably, the transmission assembly further includes a large gear and a small gear meshing with the large gear. The small gear is connected to the rotating body via a transmission shaft. The other end of the connecting rod is connected to the large gear. When the second arc-shaped hole rotates, it can trigger the connecting rod to drive the large gear to rotate in the opposite direction by a fourth angle and drive the small gear to drive the rotating body to rotate by a fifth angle. At this time, the block linkage mechanism is in the maximum bending state.

[0014] Preferably, when the second arc-shaped hole rotates to abut against the second limiting head, it rotates a third angle and then rotates a fourth angle in the opposite direction to the large gear.

[0015] Preferably, the first angle is ≤70°, the second angle is ≤60°, the third angle is ≤50°, the fourth angle is <180°, and the fifth angle is ≥360°.

[0016] Preferably, the large gear, small gear, and rotating body are all rotatably arranged on the third part.

[0017] Preferably, the third part includes a first fixing plate, on which both the large gear and the small gear are rotatably supported.

[0018] Preferably, the third part further includes a cover plate, which is detachably spliced ​​to the inner side of the first fixing plate and forms an accommodating space between the two, and the large gear and the small gear are both arranged in the accommodating space.

[0019] Preferably, it further includes a second fixing plate, which is detachably spliced ​​to the outside of the first fixing plate.

[0020] Preferably, the drive shaft passes through the first fixed plate and the second fixed plate, and one end is fitted with the pinion gear, while the other end of the drive shaft is fitted with the rotating body.

[0021] Preferably, the block linkage mechanism is at least one movable part of the toy.

[0022] Preferably, the activity is rotation.

[0023] Preferably, the rotating body is a wheel.

[0024] Preferably, the linkage mechanism of the building blocks is a joint part in the toy.

[0025] A toy provided according to the present invention includes the aforementioned block linkage mechanism.

[0026] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention adopts an integrated structure of dual-axis joints, connecting rods, and gears. When the dual joints rotate with a large range, the sliding groove and connecting rod shaft can avoid a certain distance of gap, thus preventing the teeth from coming loose. It can satisfy the high mobility of the joints while maintaining the stability of the movement, thereby improving the simulation and fun of the toy.

[0027] 2. This invention uses a linkage and gear structure instead of the traditional pure gear structure. The large gear only needs one linkage to rotate, eliminating the need for multiple speed-up and speed-down stages. This increases the transmission distance and transmission ratio. A single large gear can drive the small gear to achieve 360-degree or more rotation during the bending process of the mechanism, greatly simplifying the gear structure and reducing the number of gears and the space occupied.

Detailed Implementation

[0030] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0031] This invention provides a modular linkage mechanism, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, the mechanism can switch between an initial state and a maximum bending state, and includes a first part 1, a second part 2, a third part 3, a rotating body 7, and a transmission assembly. The first part 1 is rotatably supported on a first rotating shaft 21 of the second part 2, and the second part 2 is rotatably supported on a second rotating shaft 311 of the third part 3. The second part 2 is driven to connect with the rotating body 7 via the transmission assembly. In the initial state, the block linkage mechanism is in a straight state. When the first part 1 is driven to rotate around the first rotating shaft 21 by a first angle and then continues to rotate, it can trigger the second part 2 to rotate around the second rotating shaft 311. When the first part 1 and the second part 2 rotate together by a second angle and then continue to rotate, it can trigger the transmission assembly to drive the rotating body 7 to rotate. It should be noted that the reverse direction in this invention is... Figure 2 The counterclockwise direction is the same as the forward direction. Figure 2 The clockwise direction in the middle.

[0032] The present invention also provides a bending linkage method for a building block linkage mechanism, comprising the following steps: S1: When the block linkage mechanism is in the initial state, driving the first part 1 to rotate at the first angle and then continuing to rotate can trigger the second part 2 to rotate synchronously with the first part 1. S2: Driving the first part 1 and the second part 2 to rotate at a second angle and then continuing to rotate can trigger the transmission component to drive the rotating body 7 to rotate and can switch to the maximum bending state.

[0033] The present invention also provides a method for straightening linkage of a building block linkage mechanism, wherein the building block linkage mechanism can be adjusted from a maximum bending state to an initial state by performing the following steps: M1: When the block linkage mechanism is in the maximum bending state, driving the first part 1 to rotate in the opposite direction by a first angle and then continuing to rotate in the opposite direction can trigger the second part 2 to rotate in the opposite direction synchronously with the first part 1. M2: After driving the first part 1 and the second part 2 to rotate in opposite directions by a second angle, the rotation can trigger the transmission component to drive the rotating body 7 to rotate in opposite directions and switch back to the initial state.

[0034] Specifically, the first part 1 includes a first building block with a first arc-shaped hole 11 disposed on it; the second part 2 includes a second building block and a first rotating shaft 21, a first limiting head 22, and a second arc-shaped hole 23 disposed on the second building block; the end of the first limiting head 22 extends into the first arc-shaped hole 11; in the initial state, the end of the first limiting head 22 abuts against the upper end of the first arc-shaped hole 11, such as... Figure 2As shown, when the first part 1 is driven to rotate, the first arc-shaped hole 11 also rotates synchronously. When the first arc-shaped hole 11 rotates until the first limiting head 22 abuts against the lower end of the first arc-shaped hole 11 and continues to rotate, the first limiting head 22 will be triggered to drive the second part 2 to rotate around the second rotating shaft 311, as shown. Figure 3 As shown, the second rotating shaft 311 is preferably arranged between the first rotating shaft 21 and the second arc-shaped hole 23.

[0035] Furthermore, the transmission assembly includes a connecting rod 4, which includes a rod body, a second limiting head 41 disposed at one end of the rod body, and a third rotating shaft 42 disposed at the other end of the rod body. The end of the second limiting head 41 extends into the second arc-shaped hole 23. In the initial state, the end of the second limiting head 41 abuts against the upper end of the second arc-shaped hole 23, as shown below. Figure 2 As shown, when the first limiting head 22 is triggered to drive the second part 2 to rotate around the second rotating shaft 311, the second arc-shaped hole 23 rotates. When the second arc-shaped hole 23 rotates to the point where the second limiting head 41 abuts against the lower end of the second arc-shaped hole 23, that is, when the second limiting head 41 abuts against the lower limit 231 of the second arc-shaped hole, the second part 2 continues to rotate, which will trigger the connecting rod 4 to pull the rotating body 7 to rotate.

[0036] Furthermore, the transmission assembly is preferably a gear transmission assembly. In a preferred embodiment, the transmission assembly includes a connecting rod 4, a large gear 5, a transmission shaft 61, and a small gear 6 meshing with the large gear 5. The small gear 6 is connected to the rotating body 7 via the transmission shaft 61, and the large gear 5 is mounted on a third rotating shaft 42. Figure 1 As shown, there is one large gear 5 and two small gears 6, respectively positioned on both sides of the large gear 5 and meshing with it. The other end of the connecting rod 4 is rotatably supported on the large gear 5. When the second limiting head 41 abuts against the lower end of the second arc-shaped hole 23 and the second part 2 continues to rotate at a third angle, it triggers the second limiting head 41 to drag the connecting rod 4, causing the large gear 5 to rotate in the opposite direction at a fourth angle. At this time, the small gear 6 meshing with the large gear 5 rotates at a fifth angle, and the small gear 6 also causes the rotating body 7 to rotate at a fifth angle. At this time, the block linkage mechanism is in its maximum bending state. That is to say, when the second arc-shaped hole 23 rotates to abut against the second limiting head 41 and then rotates at a third angle, the corresponding large gear 5 rotates in the opposite direction at a fourth angle.

[0037] Specifically, the angles can be set as follows: first angle ≤ 70°, second angle ≤ 60°, third angle ≤ 50°, fourth angle < 180°, and fifth angle ≥ 360°. In a preferred embodiment, the first angle is 70°, the second angle is 60°, the third angle is 42°, the fourth angle is 120°, and the fifth angle is 360°. This invention, through a double-joint and connecting rod gear structure, can achieve a rotation angle of more than 360° for the rotating body, greatly improving the rotation angle range of the rotating body. This allows the sliding groove and connecting rod to cooperate so that when the mechanism starts to rotate in the initial state, it can avoid a certain distance before triggering the gear rotation, which can meet specific motion simulation modes and achieve dynamic simulation effects in specific scenarios.

[0038] It should be noted that the angle between the connecting rod 4 and the second rotating shaft 311 determines the rotation angle of the large gear 5. The maximum rotation angle of the connecting rod 4 is 180°, which achieves better transmission and simulation effects. In order to avoid dead points, the fourth angle is preferably ≥30° and ≤150°. During the transmission process of the connecting rod 4 to the large gear 5, the range of motion of the connecting rod 4 is limited by the range of motion of the outer armor of the product (first part 1, second part 2), and is also limited by the gearbox housing (third part 3). This invention can achieve a rotation angle of the rotating body 7 greater than 360°, that is, the rotating body 7 can rotate more than one revolution, which has better simulation effects.

[0039] like Figure 1 As shown, the large gear 5, the small gear 6, and the rotating body 7 are all rotatably arranged on the third part 3. In this embodiment, the third part 3 includes a first fixed plate 31 and a second rotating shaft 311 arranged on the first fixed plate 31. The large gear 5 and the small gear 6 are rotatably supported on the first fixed plate 31. For example, a drive shaft 61 passes through the first fixed plate 31 and is rotatably supported on the first fixed plate 31. One end of the drive shaft 61 is connected to the small gear 6, and the other end is connected to the rotating body 7. In one possible embodiment, the third part 3 further includes a cover plate 32, which is detachably spliced ​​to the inner side of the first fixed plate 31, forming an accommodating space between the cover plate 32 and the first fixed plate 31. The large gear 5 and the small gear 6 are both arranged in the accommodating space. It also includes a second fixed plate 8, which is detachably spliced ​​to the outer side of the first fixed plate 31. The transmission shaft 61 passes through the first fixed plate 31 and the second fixed plate 8, and one end is fitted with the small gear 6. The other end of the transmission shaft 61 is fitted with a rotating body 7. When the small gear 6 rotates, it drives the transmission shaft 61 to rotate. The rotation of the transmission shaft 61 drives the rotating body 7 to rotate, realizing the transmission from the small gear 6 to the rotating body 7.

[0040] It should be noted that the length of the connecting rod 4 should also have a specific correspondence with the outer diameter and included angle of the large gear 5 and the small gear 6. The length of the connecting rod 4 is 31.6 mm, the outer diameter of the small gear 6 is 10 mm, the transmission ratio of the large gear 5 and the small gear 6 is 3:1, and the ratio of the length of the connecting rod 4 to the outer diameter of the small gear 6 is close to 3:1. In this embodiment, during the transition from the initial state to the maximum bending state of the block linkage mechanism, the large gear 5 rotates 150°, while the rotating body 7 rotates 360°.

[0041] The block linkage mechanism in this invention is at least one rotatable part of the toy, with the rotating body 7 being a wheel. For example, the block linkage mechanism can be a joint in the toy. In practical applications, the block linkage mechanism can be set in any movable part of the toy, such as between the upper arm and forearm, between the waist and thigh, between the thigh and calf, between the torso and wings, between the torso and limbs, or between a limb and an end effector. By configuring a block linkage mechanism in a certain part, relative rotation, relative swinging, relative rotation, or multi-degree-of-freedom linkage of the joint structure can be achieved, thereby realizing the toy's posture changes and movement linkage, enhancing the toy's realism and fun.

[0042] The present invention also provides a toy, including a block linkage mechanism, and the toy includes, but is not limited to, doll toys, anime character models, animal model models, simulation models and various other shaped toys.

[0043] The working principle of this invention is as follows: In the initial state, such as Figure 2 As shown, the first limiting head 22 and the second limiting head 41 abut against the upper end of the first arc-shaped hole 11 and the upper end of the second arc-shaped hole 23, respectively.

[0044] When the first part 1 is driven to rotate around the first pivot 21 by a first angle, the first limiting head 22 abuts against the lower end of the first arc-shaped hole 11, as follows: Figure 3 As shown.

[0045] When the first part 1 is driven to drive the second part 2 to continue rotating around the second shaft 311 at a second angle, the second limiting head 41 abuts against the lower end of the second arc-shaped hole 23. When the first part 1 drives the second part 2 to continue rotating around the second shaft 311 to a third angle, the second part 2 drives the upper end of the connecting rod 4 to move upward through the second limit head 41, and then the lower end of the connecting rod 4 drives the large gear 5 to rotate in the opposite direction around the axis to a fourth angle, such as... Figure 4 As shown, since the large gear 5 and the small gear 6 are meshed and connected, the large gear 5 drives the small gear 6 to rotate the rotating body 7 by the fifth angle. At this time, the block linkage mechanism is in the maximum bending state.

[0046] When the first part 1 is driven to rotate in the opposite direction around the first pivot 21 by a first angle, the first limiting head 22 abuts against the upper end of the first arc-shaped hole 11.

[0047] When the first part 1 is driven to drive the second part 2 to continue to rotate in the opposite direction around the second rotating shaft 311 by a second angle, the second limiting head 41 abuts against the upper end of the second arc-shaped hole 23. When the first part 1 drives the second part 2 to continue rotating in the opposite direction around the second rotating shaft 311 for a third angle, the second part 2 drives the upper end of the connecting rod 4 to move downward through the second limit head 41. Then, the lower end of the connecting rod 4 drives the large gear 5 to rotate around the axis for a fourth angle. Since the large gear 5 is meshed with the small gear 6, the large gear 5 drives the small gear 6 to drive the rotating body 7 to rotate in the opposite direction for a fifth angle. At this time, the block linkage mechanism is in the initial state.
