Description

Technical Field

[0001] This application relates to the field of toy ornaments, and in particular to a carousel. Background Technology

[0002] Carousel figurines typically mimic the driving mechanism of a carousel in an amusement park, causing it to rotate and move up and down, while also incorporating lighting effects to enhance their visual appeal.

[0003] Existing carousels typically use a motor to drive a complex linkage mechanism to move the horse up and down and rotate circumferentially. This results in a complex structure and high production costs. Summary of the Invention

[0004] In order to reduce the production cost of carousels, this application provides a carousel.

[0005] The carousel provided in this application adopts the following technical solution: A carousel includes a base, a turntable, and a drive assembly. The turntable is horizontally rotatably connected to the base. Multiple vertical lifting rods are movably inserted into the turntable at intervals along the circumferential direction. A carousel body is fixedly installed on each lifting rod. The base is provided with a circular track. The surface of the circular track is wavy along the circumferential direction. The circular track is located below the turntable. The lower end of the lifting rod contacts the upper surface of the circular track. The drive assembly drives the turntable to rotate.

[0006] By adopting the above technical solution, the turntable is driven to rotate by the drive component, and multiple lifting rods follow the rotation of the turntable. At the same time, the lower end of the lifting rods moves up and down along the wave-shaped circular track, thereby realizing the up and down movement of the rocking horse body on the lifting rods during rotation. Therefore, compared with realizing the up and down movement of the rocking horse body through a complex linkage mechanism, the structure is simplified, thereby reducing production costs.

[0007] Preferably, the drive assembly includes a motor, an external gear, and an internal gear. The motor is mounted on a base, the external gear is coaxially fixed on the motor shaft, the internal gear is fixed on the lower surface of the turntable, and the center of the internal gear coincides with the center of the turntable. The external gear and the internal gear mesh with each other.

[0008] By adopting the above technical solution, the external gear is driven by a motor, which in turn drives the turntable fixed on the internal gear to rotate. Therefore, the drive component has a simple structure and low cost.

[0009] Preferably, at least two annular tracks are provided, the centers of the two annular tracks coincide, and the diameters of the two annular tracks are different. Two sets of multiple lifting rods are provided, distributed along the circumference of the turntable, and the lower ends of the two sets of lifting rods are in contact with the upper surfaces of the two annular tracks respectively.

[0010] By adopting the above technical solution, the driving component simultaneously drives the two sets of lifting rods to rotate, and the two sets of lifting rods are driven up and down by two ring guide rails. Thus, the driving component synchronously realizes the rotation and lifting of multiple sets of carousel bodies, and improves the viewing experience of the carousel.

[0011] Preferably, the base is cylindrical, with a circular opening on the upper surface of the base, and an annular support seat is provided at the bottom of the base, with the lower surface of the turntable in contact with the upper surface of the annular support seat.

[0012] By adopting the above technical solution, the turntable rotates within the circular opening under the support of the annular support base, thereby improving the stability of the turntable's rotation.

[0013] Preferably, the lower surface of the turntable is provided with a plurality of arc-shaped limiting pieces at intervals along the circumferential direction, and the plurality of arc-shaped limiting pieces are in contact with the side wall of the annular support.

[0014] By adopting the above technical solution, the rotational stability of the turntable is further improved by using multiple arc-shaped limiting plates and annular support seats set on the lower surface of the turntable for rotational limiting.

[0015] Preferably, a hollow support column is provided in the middle of the turntable, a canopy is provided at the upper end of the support column, a plurality of ambient lights are provided around the canopy, a conductive ring is provided on the lower surface of the turntable, the ambient lights are electrically connected to the conductive ring, and a metal spring is provided on the base, the metal spring contacting the surface of the conductive ring.

[0016] By adopting the above technical solution, the support column and the canopy rotate with the turntable, and the metal spring on the base contacts the conductive ring of the turntable, thereby realizing the electrical connection between the power supply on the base and the ambient light, thus improving the visual appeal of the carousel.

[0017] Preferably, the lifting rod includes a lead screw section at the upper end, and a ball nut is vertically fixed on the lower surface outside the canopy, with the lead screw section of the lifting rod connected to the ball nut.

[0018] By adopting the above technical solution, the lead screw section at the upper end of the lifting rod is connected to the ball screw nut. Since the ball screw pair does not have a self-locking function, the drive component drives the turntable to rotate the lifting rod and, under the guidance of the circular track, it rotates itself with the help of the ball screw nut. Thus, the rocking horse body on the lifting rod rotates along with the turntable, thereby improving the ornamental value of the rocking horse body.

[0019] Preferably, the lower end of the lifting rod is hemispherical.

[0020] By adopting the above technical solution, the lower end of the lifting rod is set in a hemispherical shape, thereby reducing the friction between the lifting rod and the circular track, thus facilitating the movement and rotation of the lifting rod.

[0021] Preferably, the ceiling is equipped with a trigger switch that works in conjunction with the lifting rod to control the intermittent operation of the ambient light. The trigger switch includes a mounting plate, a movable plate, a trigger spring, two springs, and two metal conductive plates. The mounting plate is fixedly installed inside the ceiling, and the movable plate is located below the mounting plate. The two springs are respectively fixed between the mounting plate and the movable plate and located on both sides of the movable plate. The two metal conductive plates are fixed at intervals on the surface of the mounting plate opposite the movable plate, and the two metal conductive plates are electrically connected to the ambient light. The trigger spring is fixed on the surface of the movable plate opposite the mounting plate. During the lifting rod's ascent, it pushes the movable plate closer to the mounting plate, so that the trigger spring simultaneously contacts and conducts electricity with the two metal conductive plates.

[0022] By adopting the above technical solution, during the upward movement of the lifting rod, the movable plate is pushed close to the mounting plate, so that the trigger spring on the movable plate simultaneously contacts the two metal conductive pieces on the mounting plate, thereby energizing the ambient light. This controls the ambient light to emit light intermittently during the lifting and rotation of the carousel, thus improving the carousel's visual appeal, and eliminating the need for intermittent operation of the ambient light via a circuit board.

[0023] Preferably, multiple trigger switches are provided, and each trigger switch cooperates with the corresponding lifting rod to control the intermittent operation of the corresponding ambient light.

[0024] By adopting the above technical solution, the ambient lights are intermittently controlled by multiple trigger switches and multiple lifting rods, thereby improving the visual appeal of the carousel.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The turntable is driven to rotate by the drive component, and multiple lifting rods follow the rotation of the turntable. At the same time, the lower end of the lifting rods moves up and down along the wave-shaped circular track, thereby realizing the up and down movement of the rocking horse body on the lifting rods during rotation. Therefore, compared with the rocking horse body moving up and down through a complex linkage mechanism, the structure is simplified, thereby reducing production costs.

[0027] 2. The lead screw section at the upper end of the lifting rod is connected to the ball screw nut. Since the ball screw pair does not have a self-locking function, the drive component drives the turntable to rotate the lifting rod and moves it up and down under the guidance of the circular track. With the cooperation of the ball screw nut, the lifting rod rotates itself, so that the rocking horse body on the lifting rod also rotates as it follows the turntable, thereby improving the ornamental value of the rocking horse body.

[0028] 3. During the ascent of the lifting rod, the movable plate is pushed close to the mounting plate, causing the trigger spring on the movable plate to simultaneously contact the two metal conductive pieces on the mounting plate, thereby energizing the ambient light. This controls the ambient light to emit light intermittently during the ascent, descent, and rotation of the carousel, thus enhancing the carousel's visual appeal without requiring a circuit board for the ambient light to operate intermittently.

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a carousel. (See also...) Figure 1 The carousel includes a base 1, a turntable 2, a support column 3, and a canopy 4. The base 1 is cylindrical and hollow inside. A circular opening 11 communicating with the interior of the base 1 is opened on the upper surface of the base 1. The diameter of the turntable 2 is adapted to the circular opening 11, and the turntable 2 is horizontally connected to the circular opening 11 of the base 1. A circular platform 21 is provided on the upper surface of the turntable 2. The lower end of the support column 3 is fixed to the middle position of the upper surface of the circular platform 21, and the canopy 4 is fixed to the upper end of the support column 3.

[0037] Reference Figure 1 and Figure 2 Multiple vertical lifting rods 5 are inserted at intervals along the circumference of the upper surface of the turntable 2. Multiple clearance holes 22 are also spaced at intervals along the circumference of the upper surface of the turntable 2. The lifting rods 5 extend through the clearance holes 22 into the interior of the base 1. A rocking horse body is fixedly mounted on each lifting rod 5. The base 1 is provided with a circular track 12, the surface of which is wavy along the circumference. The circular track 12 is located below the turntable 2. The lower ends of the lifting rods 5 contact the upper surface of the circular track 12, and the lower ends of the lifting rods 5 are semi-circular. The circular track 12 and the center of the turntable 2 are on the same straight line. A drive assembly is installed inside the base 1, which drives the turntable 2 to rotate. Driven by the drive assembly, the multiple lifting rods 5 rotate with the turntable 2, and simultaneously, the lower ends of the lifting rods 5 move up and down along the wavy circular track 12, thus realizing the up and down movement of the rocking horse body 6 on the lifting rods 5 during rotation. Therefore, compared with a complex linkage mechanism to achieve the up and down movement of the rocking horse body 6, the structure is simplified, thereby reducing production costs.

[0038] Reference Figure 1 and Figure 2 Furthermore, at least two annular tracks 12 are provided. In this embodiment, two annular tracks 12 are provided, with their centers coinciding and their diameters being different. Two sets of lifting rods 5 are arranged along the circumference of the turntable 2, with the lower ends of the two sets of lifting rods 5 contacting the upper surfaces of the two annular tracks 12 respectively. The two sets of lifting rods 5 are simultaneously driven to rotate by a drive assembly, and simultaneously moved up and down by two annular guide rails. This allows the drive assembly to synchronously achieve the rotation and lifting of multiple carousel bodies 6, thus enhancing the carousel's visual appeal.

[0039] Reference Figure 2 and Figure 3 To achieve the rotation of turntable 2, the drive assembly specifically includes a motor 13, an external gear 14, and an internal gear 23. Motor 13 is mounted at the bottom of the base 1. The external gear 14 is coaxially fixed to the rotating shaft of motor 13. Motor 13 is an off-axis motor. The internal gear 23 is fixed to the lower surface of turntable 2, and the center of the internal gear 23 coincides with the center of the turntable 2. The external gear 14 and internal gear 23 mesh with each other. Motor 13 drives the external gear 14, thereby causing the turntable 2 fixed to the internal gear 23 to rotate. Therefore, the drive structure is simple, stable, and low-cost.

[0040] Reference Figure 2 and Figure 3An annular support seat 15 is provided at the bottom of the base 1, and an annular support column 3 is located between two annular tracks 12. The lower surface of the turntable 2 is in contact with the upper surface of the annular support seat 15. Multiple arc-shaped limiting pieces 24 are spaced apart along the circumferential direction on the lower surface of the turntable 2, and the multiple arc-shaped limiting pieces 24 are in contact with the side wall of the annular support seat 15. The turntable 2 is rotatably connected to the circular opening 11 by the support of the annular support seat 15 and is rotatably limited by the multiple arc-shaped limiting pieces 24, thereby improving the rotational stability of the turntable 2.

[0041] Reference Figure 2 and Figure 3 The bottom of the base 1 has a protrusion 16 that protrudes upwards. A metal spring 17 is fixedly installed on the upper end of the protrusion 16. A conductive ring 25 is installed on the lower surface of the turntable 2. One end of the metal spring 17 is connected to the power supply through a wire, and the other end of the metal spring 17 is in contact with the surface of the conductive ring 25.

[0042] Reference Figure 4 and Figure 5 The support column 3 and the canopy 4 are hollow inside. Multiple lamp holders 41 are arranged at intervals along the circumference inside the canopy 4. Each lamp holder 41 is equipped with an ambient light 42. The ambient light 42 is electrically connected to the conductive ring 25 through wires. Multiple transparent windows 43 are arranged at intervals on the periphery of the canopy 4 to enhance the viewing experience of the carousel.

[0043] Reference Figure 4 and Figure 5 The lifting rod 5 includes a lead screw section at its upper end, which extends movably into the canopy 4. A ball bearing nut 44 is fixedly installed on the lower outer surface of the canopy 4, and the lead screw section of the lifting rod 5 is connected to the ball bearing nut 44. The ball bearing nut 44 is fixed to the canopy 4, and the lead screw section at the upper end of the lifting rod 5 is connected to the ball bearing nut 44. Since the ball bearing screw pair does not have a self-locking function, the drive assembly drives the turntable 2 to rotate the lifting rod 5 and guides it up and down under the guidance of the circular track 12. With the cooperation of the ball bearing nut 44, the lifting rod 5 rotates itself, so that the rocking horse body 6 on the lifting rod 5 also rotates as it follows the rotation of the turntable 2, thereby improving the visual appeal of the rocking horse body 6.

[0044] Reference Figure 4 and Figure 5The ceiling 4 is equipped with multiple trigger switches 7 that work in conjunction with a set of lifting rods 5 to control the intermittent operation of the ambient light 42. Each trigger switch 7 includes a mounting plate 71, a movable plate 72, a trigger spring 73, two springs 74, and two metal conductive plates 75. The mounting plate 71 is horizontally fixed to one side of the lamp holder 41, and the movable plate 72 is located below the mounting plate 71. The two springs 74 are respectively fixed between the mounting plate 71 and the movable plate 72 and are located on both sides of the movable plate 72. The two metal conductive plates 75 are fixed at intervals on the surface of the mounting plate 71 relative to the movable plate 72, and the two metal conductive plates 75 are electrically connected to the ambient light 42. The trigger spring 73 is fixed on the surface of the movable plate 72 relative to the mounting plate 71. The upper end of the lifting rod 5 is rotatably connected to the lower surface of the movable plate 72 through a bearing. During the upward movement of the lifting rod 5, it pushes the movable plate 72 closer to the mounting plate 71 so that the trigger spring 73 simultaneously contacts and conducts electricity with the two metal conductive plates 75. During the ascent of the lifting rod 5, it pushes the movable plate 72 closer to the mounting plate 71, causing the trigger spring 73 on the movable plate 72 to simultaneously contact the two metal conductive pieces 75 on the mounting plate 71. This powers the ambient light 42, allowing it to illuminate intermittently in conjunction with the carousel body 6 during its ascent, descent, and rotation, thus enhancing the carousel's visual appeal without requiring a circuit board for intermittent operation of the ambient light 42. Furthermore, during the descent of the lifting rod 5, the spring 74 ensures a stable descent.

[0045] The implementation principle of a carousel according to this application embodiment is as follows: A drive assembly drives the turntable 2 to rotate, and multiple lifting rods 5 follow the rotation of the turntable 2. Simultaneously, the lower ends of the lifting rods 5 move up and down along the wave-shaped circular track 12, thus achieving the up-and-down movement of the carousel body 6 on the lifting rods 5 during rotation. The upper end of the lifting rod 5 is connected to a ball screw nut 44. Since the ball screw pair does not have a self-locking function, the drive assembly drives the turntable 2 to rotate the lifting rods 5, and during the up-and-down movement guided by the circular track 12, the lifting rods 5 rotate themselves with the cooperation of the ball screw nut 44. Furthermore, during the upward movement of the lifting rods 5, the movable plate 72 is pushed closer to the mounting plate 71, causing the trigger spring 73 on the movable plate 72 to simultaneously contact the two metal conductive pieces 75 on the mounting plate 71. This powers the ambient light 42, controlling it to emit intermittent light during the up-and-down movement and rotation of the carousel body 6, thereby enhancing the carousel's visual appeal.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
