Description

Technical Field

[0001] This utility model relates to the technical field of toys, and in particular to a music box component structure.

[0002] Background Technology .

[0003] Music boxes, as decorative items or ornaments, are usually arranged in different scenes for people to enjoy. In some situations, people also hope that the scenes of the music box can be more vivid and rich to enhance the atmosphere, such as simulating animal movements, such as a dog wagging its tail. In the existing technology, a driving structure is usually set inside the animal model to drive the dog's tail to wag. However, setting up the driving structure in this way will make the animal model relatively large, which is inconvenient to set in the limited scene space of the music box. Utility Model Content

[0004] The purpose of this invention is to provide a music box component structure that solves the technical problem of simulating the swaying of an animal's tail.

[0005] To achieve the above objectives, the solution of this utility model is: a music box component structure, including a vertical shaft, a tail rod, a turntable, a connecting rod, and a swing rod; The vertical axis is set inside the animal model body. The vertical axis extends longitudinally and can rotate horizontally around the axis. The tail rod is fixed to the top side of the vertical axis and extends laterally to support the tail of the animal model. The turntable is circular with its axis extending longitudinally. The turntable can rotate horizontally around its axis. A first pivot shaft is formed on the turntable. The axis of the first pivot shaft is parallel and spaced apart from the axis of the turntable. One end of the connecting rod is pivotally connected to the turntable through the first pivot shaft. The other end of the connecting rod is pivotally connected to one end of the swing rod. The other end of the swing rod is fixed to the vertical axis. After the turntable rotates around the axis, the connecting rod drives one end of the swing rod to swing back and forth around the vertical axis, so that the vertical axis can rotate back and forth within a predetermined angle, thereby driving the tail rod to swing back and forth laterally.

[0006] Furthermore, the relative positions and dimensions of the turntable, connecting rod, and pendulum allow for a critical position between the two extreme positions of the tail rod's swing trajectory. The tail rod can accelerate from the extreme position to the critical position, and decelerate from the critical position to the extreme position, thus causing the tail rod to swing at varying speeds to simulate the tail-wagging motion of an animal.

[0007] Furthermore, it also includes a drive gear that extends laterally and can rotate horizontally around an axis. A first driven gear is formed on the bottom side of the turntable, and the drive gear meshes with one side of the first driven gear to drive the turntable to rotate horizontally.

[0008] Furthermore, it also includes a turntable, with a space between the turntable and the turntable. The driving gear is located between the turntable and the turntable, and a second driven gear is formed on the bottom side of the turntable. The driving gear meshes with one side of the second driven gear so that when the driving gear rotates, it can simultaneously drive the first driven gear and the second driven gear to rotate, so that the turntable and the turntable rotate at the same time.

[0009] Furthermore, it also includes a fixed platform, which is circular, and a turntable, which is annular. The turntable is fitted onto the fixed platform and rotates around the outer periphery of the fixed platform. A first model is fixed on the fixed platform, and a second model is fixed on the turntable, so that when the turntable rotates relative to the fixed platform, the second model rotates around the outer periphery of the first model to different positions.

[0010] Furthermore, the drive gear is connected to a drive motor, and a mounting hole is formed on the bottom side of the drive gear. The mounting hole extends along the axis of the drive gear, and the output shaft of the drive motor extends longitudinally and is inserted into the mounting hole upwards, engaging circumferentially with the mounting hole to drive the drive gear to rotate horizontally around the axis.

[0011] Furthermore, it also includes a guide member that extends longitudinally and is supported on the bottom side of the swing arm. Its cross-section is arc-shaped, and the arc-shaped extension direction is consistent with the swing trajectory of the swing arm. A guide shaft is provided on the swing arm, and the guide member is limited to one side of the guide shaft so that the guide shaft slides along the extension direction of the side wall of the guide member when the swing arm swings.

[0012] Furthermore, the bottom end of the vertical axis extends downwards out of the animal model body, and the pendulum is located below the animal model and fixed to the part of the vertical axis that extends out of the animal model body.

[0013] The beneficial effects of this utility model after adopting the above solution are as follows: When the turntable rotates horizontally, it can drive one end of the connecting rod to make a circular motion around the axis of the turntable, causing the connecting rod to drive one end of the swing rod to swing around the other end of the swing rod. The other end of the swing rod is fixed to the vertical axis, and the vertical axis extends longitudinally, allowing it to rotate horizontally around its axis. When one end of the swing rod swings, the other end of the swing rod drives the vertical axis to reciprocate horizontally around the axis at a predetermined angle, thereby causing the tail rod fixed to the top side of the vertical axis to also swing horizontally back and forth, simulating the movement of an animal's tail and increasing the fun. In addition, the vertical axis extends longitudinally and is set on the moving... Inside the animal model, the tail rod is fixed to the top side of the vertical axis and extends laterally to support the tail of the animal model. The animal model is placed on a platform inside the music box. By connecting the pendulum to the bottom side of the vertical axis, the drive structure consisting of the turntable, connecting rod, and pendulum is set inside the platform and outside the animal model. This allows the animal model to be made relatively small, making it easy to place inside the music box. The tail rod is driven to swing through the vertical axis, allowing the animal model to be placed in various postures such as lying down, semi-squatting, forward-leaning, backward-leaning, or standing, simulating the tail-wagging movements of the animal in various postures.

Detailed Implementation

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] like Figure 1-8 As shown, a music box component structure includes a vertical shaft 1, a tail rod 2, a turntable 3, a connecting rod 4, and a swing rod 5. The vertical shaft 1 is set inside the animal model body, extends longitudinally, and the bottom end of the vertical shaft 1 extends downward out of the animal model body. The vertical shaft 1 can rotate horizontally around the axis. The tail rod 2 is fixed to the top side of the vertical shaft 1 and extends laterally to support the tail of the animal model.

[0026] Key points combined Figure 8 As shown, the turntable 3 is circular with its axis extending longitudinally. The turntable 3 can rotate horizontally around its axis. A first pivot shaft 31 is formed on the turntable 3, and the axis of the first pivot shaft 31 is parallel and spaced apart from the axis of the turntable 3. A first pivot hole 41 and a second pivot hole 42 are formed at both ends of the connecting rod 4, respectively. One end of the connecting rod 4 is pivotally connected to the turntable 3 through the first pivot shaft 31. During installation, the first pivot hole 41 of the connecting rod 4 is fitted onto the first pivot shaft 31, so that the first pivot hole 41 and the first pivot shaft 31 are pivotally engaged. The top surface of one end of the swing rod 5 protrudes upward to form a second pivot shaft 52. The other end of the connecting rod 4 is pivotally connected to one end of the swing rod 5 through the second pivot shaft 52. During installation, the second pivot hole 42 is fitted onto the second pivot shaft 52, so that the second pivot hole 42 and the second pivot shaft 52 are pivotally engaged. One end of the connecting rod 4 is fixed to the vertical axis 1 so that when the turntable 3 rotates around the axis, one end of the connecting rod 4 makes a circular motion around the axis of the turntable 3, and the other end of the connecting rod 4 drives one end of the swing rod 5 to swing around the vertical axis 1, so that the vertical axis 1 can rotate back and forth around the axis within a predetermined angle, thereby driving the tail rod 2 to swing back and forth laterally to simulate the movement of the animal's tail. The vertical axis 1 extends longitudinally, making it easier to match the animal's posture and simulate the tail wagging movement of the animal in various postures, such as lying down, half squatting, forward tilting, backward tilting, or standing postures. Specifically, the swing rod 5 is located below the animal model and is fixed to the part of the vertical axis 1 that extends out of the animal model, so that the turntable 3, connecting rod 4 and swing rod 5 are set outside the animal model. Of course, in other embodiments, the swing rod 5 can also be fixed at other positions on the vertical axis 1.

[0027] In this specific embodiment, the relative positions and dimensions of the turntable 3, connecting rod 4, and swing rod 5 enable the tail rod 2 to swing laterally back and forth between two extreme positions at a predetermined angle. There is a critical position between the two extreme positions. The tail rod 2 can accelerate from the extreme position to the critical position and decelerate from the critical position to the extreme position, thus causing the tail rod 2 to swing at varying speeds to simulate the tail-wagging motion of an animal. Those skilled in the art can achieve this function by designing the relative positions and dimensions of the turntable 3, connecting rod 4, and swing rod 5. The specific positions and dimensions are not limited. Figure 4 As shown, tail rod 2 is at the critical position, pendulum 5 has the maximum speed, turntable 3 continues to rotate counterclockwise, pendulum 5 decelerates, causing tail rod 2 to decelerate and swing to one of its extreme positions (e.g., Figure 5As shown), turntable 3 continues to rotate counterclockwise, connecting rod 4 pulls swing rod 5 to move in the opposite direction, swing rod 5 accelerates, causing tail rod 2 to accelerate from its extreme position to the critical position. Figure 6 This is a schematic diagram showing the tail rod 2 reaching the critical position. The turntable 3 continues to rotate counterclockwise, the swing arm 5 decelerates, and the tail rod 2 decelerates and swings to another extreme position (such as...). Figure 7 As shown), turntable 3 continues to rotate counterclockwise, causing the swing arm 5 to move in the opposite direction and swing towards another extreme position, thus achieving reciprocating swing.

[0028] like Figure 1 As shown, it also includes a guide member 12 and a base 14. The guide member 12 extends longitudinally, and its bottom end is fixedly connected to the base 14. The top end of the guide member 12 is supported on the bottom side of the swing rod 5. Its cross-section is arc-shaped, and the arc-shaped extension direction is consistent with the swing trajectory of the swing rod 5. A guide shaft 51 is provided on the swing rod 5. The guide member 12 is limited to one side of the guide shaft 51 so that when the swing rod 5 swings, the guide shaft 51 slides along the extension direction of the side wall of the guide member 12, making the swing of the swing rod 5 more stable.

[0029] Key points combined Figure 2-3 As shown, it also includes a drive gear 6, which extends laterally and can rotate horizontally around an axis. A first driven gear 32 is formed on the bottom side of the turntable 3. The drive gear 6 meshes with one side of the first driven gear 32 to drive the turntable 3 to rotate horizontally. Specifically, the drive gear 6 is connected to a drive motor 11. A mounting hole 61 is formed on the bottom side of the drive gear 6. The mounting hole 61 extends longitudinally along the axis of the drive gear 5. The output shaft 13 of the drive motor 11 extends longitudinally and is inserted upward into the mounting hole 61, engaging circumferentially with the mounting hole 61 to drive the drive gear 6 to rotate horizontally around an axis. Specifically, the mounting hole 61 is a quadrilateral structure, and the output shaft 13 is a quadrilateral structure. Its outer contour is consistent with the inner contour of the mounting hole 61. It also includes a power supply 15, which is electrically connected to the drive motor 11 to supply power to the drive motor 11. The power supply 15 can be an external power source or a battery, without specific limitations. The drive motor 11 can be any existing micro DC motor. After being powered on, the drive motor 11 can drive the drive gear 6 to rotate horizontally.

[0030] Key points combined Figure 2 As shown, it also includes a turntable 7, which is spaced apart from the turntable 3. The driving gear 6 is located between the turntable 7 and the turntable 3. A second driven gear 71 is formed on the bottom side of the turntable 7. The driving gear 6 meshes with one side of the second driven gear 71 so that when the driving gear 6 rotates horizontally, it can simultaneously drive the first driven gear 32 and the second driven gear 71 to rotate, so that the turntable 7 and the turntable 3 rotate at the same time.

[0031] Key points combined Figure 2-3As shown, it also includes a fixed platform 8, which is circular, and a turntable 7, which is annular. The turntable 7 is fitted onto the fixed platform 8 and rotatably engages with the outer circumference of the fixed platform 8. Specifically, a support platform 16 is fixedly installed on the base 15. The fixed platform 8 is detachably installed on the support platform 16. The bottom end of the fixed platform 8 protrudes downward to form a protrusion. The outer diameter of the protrusion is smaller than the outer diameter of the support platform 16 and smaller than the outer diameter of the fixed platform 8. After the fixed platform 8 is installed on the support platform 16, an annular groove 17 is formed between the fixed platform 8 and the support platform 16. The inner ring of the turntable 7 has an annular boss 18 protruding radially inward. The inner diameter of the annular boss 18 is smaller than that of the support platform 16 so that it can be placed on the support platform 16. The annular boss 18 can rotatably engage with the annular groove 17 so that after the drive gear 6 rotates, it can drive the turntable 7 to rotate horizontally relative to the fixed platform 8. During installation, the turntable 7 is first placed on the support platform 16, and then the fixed platform 8 is installed on the support platform 16 so that the turntable 7 is rotatably positioned on the outer circumference of the fixed platform 8.

[0032] Key points combined Figure 1 As shown, a first model 9 is fixed on a fixed platform 8, and a second model 10 is fixed on a turntable 7. When the turntable 7 rotates, the second model 10 will move in a circular motion around different positions on the outer periphery of the first model 9. Specifically, the first model 9 can be a Christmas tree model and the second model 10 can be a toy train model. Of course, the first model 9 and the second model 10 can also be set to other models to form different scenes.

[0033] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
