Description

Technical Field

[0001] This utility model relates to the field of toy mechanism technology, and in particular to a rocking mechanism. Background Technology

[0002] Toys are devices for play and entertainment. In recent years, toys featuring anthropomorphic, animal, or cartoon characters have become increasingly popular, appealing not only to children but also to many adults. Most of these toys on the market are static, relying heavily on decorative elements to embellish their appearance, resulting in limited playability and low entertainment value. Some toys incorporate internal mechanisms to achieve certain dynamic functions, but these mechanisms are structurally complex and expensive. Utility Model Content

[0019] Reference Figures 1 to 5 This invention provides a rocking mechanism that, by adding appropriate decorations to the outside of the rocking mechanism, can be transformed into a toy for the entertainment of children and adults. The rocking mechanism mentioned here typically simulates a lying position during use.

[0020] The rocking mechanism includes a housing 1, a drive unit 2, an eccentric transmission wheel 3, a connecting rod 4, and a rocking body unit 5. The drive unit 2 is connected inside the housing 1 and is driven by the eccentric transmission wheel 3. Both ends of the connecting rod 4 are rotatably connected to the eccentric transmission wheel 3 and the rocking body unit 5, respectively. The middle of the rocking body unit 5 is rotatably connected to the housing 1. The housing 1 has a movable slot 11 for the rocking body unit 5 to move. The rotation of the eccentric transmission wheel 3 drives the connecting rod 4, causing it to rotate and move simultaneously. The connecting rod 4 drives the rocking body unit 5 to rotate relative to the movable slot 11, creating a reciprocating rocking motion. With the addition of external decorations, the rocking mechanism can form a toy with a rocking function, allowing the toy's simulated body to rock relative to the toy's simulated head, enriching the toy's playability and making it more attractive. The drive unit 2, eccentric transmission wheel 3, connecting rod 4, and rocking body unit 5 work together to form a simpler transmission method, which is more energy-efficient and cost-effective.

[0021] As an optional implementation, the rocking body unit 5 includes a rotating main board 51, upper limb simulators 52, and lower limb simulators 53. The rotating main board 51 is rotatably connected to the connecting rod 4 and the housing 1. There are two upper limb simulators 52 and two lower limb simulators 53. The two upper limb simulators 52 are symmetrically connected to both sides of the rotating main board 51, and the two lower limb simulators 53 are symmetrically connected to both sides of the rotating main board 51. The two upper limb simulators 52 and the two lower limb simulators 53 can simulate the toy's body more realistically.

[0022] As an optional implementation, a connecting post 511 is provided on the rotating main board 51, and a connecting sleeve 41 is provided at the end of the connecting rod 4 that is rotatably connected to the rotating main board 51. The connecting sleeve 41 is sleeved on the outside of the connecting post 511 so that the connecting sleeve 41 and the connecting post 511 can rotate relative to each other. Since the connecting rod 4 can rotate and move simultaneously under the drive of the eccentric transmission wheel 3, it can drive the rotating main board 51 to rotate relative to the housing 1.

[0023] As an optional implementation, the rotating main board 51 is provided with a connection hole 512, and the housing 1 is provided with a support column 12 at the connection between it and the rotating main board 51. The support column 12 passes through the connection hole 512 and there is a gap between the two, so that the rotating main board 51 can rotate relative to the axis of the support column 12.

[0024] As an optional implementation, a limiting groove 513 is provided on the rotating main board 51. The shape of the limiting groove 513 matches the rotation path of the rocking body unit 5. The housing 1 is provided with a limiting post 13 on the moving path of the limiting groove 513. The limiting post 13 can slide relative to the limiting groove 513 and can limit the movement of the rocking body unit 5. The two extreme sliding positions of the limiting post 13 correspond to the two extreme rotation positions of the rocking body unit 5 relative to the housing 1.

[0025] As an optional implementation, the drive unit 2 includes a motor 21, a belt pulley drive assembly 22, and a gear drive assembly 23. The output end of the motor 21 is connected to the belt pulley drive assembly 22, the belt pulley drive assembly 22 is connected to the gear drive assembly 23, and the gear drive assembly 23 is connected to the eccentric drive wheel 3.

[0026] As an optional implementation, the belt pulley drive assembly 22 includes a first pulley 221, a belt, and a second pulley 222. The output shaft of the motor 21 is connected to the first pulley 221. The belt is connected to both the first pulley 221 and the second pulley 222. The second pulley 222 is connected to the gear drive assembly 23.

[0027] As an optional implementation, the gear transmission assembly 23 includes a plurality of gear bodies that are sequentially meshed and connected in transmission. The gear body at the beginning rotates coaxially with the second pulley 222, and the gear body at the end rotates coaxially with the eccentric transmission wheel 3.

[0028] After the output shaft of motor 21 is started, it can drive the first pulley 221 to rotate, which in turn drives the belt drive, which in turn drives the second pulley 222 to rotate, which in turn drives the gear body located at the beginning to rotate, which in turn drives all the gear bodies to rotate in sequence, which in turn drives the gear body located at the end to rotate, which in turn drives the eccentric transmission wheel 3 to rotate.

[0029] As an optional implementation, a switch 6 and a power supply 7 are also included. The switch 6 is disposed on the housing 1, and the power supply 7 is disposed inside the housing 1. The switch 6, the power supply 7 and the drive unit 2 form a closed circuit through wires. The power supply 7 can supply power to the motor 21 of the drive unit 2, and the switch 6 can control the opening or closing of the closed circuit, thereby controlling the start and stop of the motor 21.

[0030] Based on this, a control module is also included. The control module is preferably set in the closed loop. It can control the action frequency and action time of the drive unit 2 to form different dancing states and further enrich the dancing effect. In this embodiment, the control module can preferably be a PCB integrated circuit board, which is electrically connected to the closed loop. Its structure and control principle have a lot of existing technology, so it will not be described in detail or shown in the accompanying drawings.

[0031] As an optional implementation, the rotating main board 51, the upper limb simulator 52, and the lower limb simulator 53 are connected as a single unit. This integrated connection gives the rocking body unit 5 good structural strength. Even when used by a child and subjected to external force, the upper limb simulator 52 and the lower limb simulator 53 maintain good structural strength and are protected from damage.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
