Description

Technical Field

[0001] This utility model relates to a doll, and more specifically to a doll with a rotatable outer ring on the bottom surface of its base. Background Technology

[0002] Currently, many dolls move by using a drive unit to rotate a rotating device (usually a caster wheel) located in the base.

[0003] For example, the applicant's earlier application, publication number CN218306130U, entitled "Toy Dancing Princess with Quickly Replaceable Lower Body," discloses a toy dancing princess that includes an interlocking upper body assembly and a lower body assembly. The lower body assembly includes a lower body shell, a chassis, a battery, a motor, and a transmission mechanism. The lower body shell, battery, and motor are respectively mounted on the chassis, and the transmission mechanism is mounted on the chassis and the inner wall of the lower body shell. The battery and motor are electrically connected, and the motor is connected to the transmission mechanism. The lower body assembly is characterized by further including a liftable interlocking slot and a first magnet; the upper body assembly includes an upper body shell, two arms, a liftable frame, and a second magnet. The chassis bottom is equipped with a rotating device, which includes a mounting plate, a protective ring, a vertical rotating shaft, a horizontal rotating shaft, a pinion, a driven gear, a second crown gear, and two wheels. The vertical rotating shaft is rotatably mounted on the chassis, the mounting plate is fixed on the vertical rotating shaft, the protective ring is mounted on the mounting plate and is sleeved on the outside of the mounting plate, the driven gear is mounted on the top of the vertical rotating shaft and meshes with a gear of the gear transmission mechanism, the second crown gear is mounted on the bottom of the vertical rotating shaft, the horizontal rotating shaft is rotatably mounted on the mounting plate, the two wheels are respectively mounted on both ends of the horizontal rotating shaft, the pinion is fixed on the horizontal rotating shaft and meshes with the second crown gear.

[0004] However, because the rotation mechanism drives the movement of the doll, its trajectory is relatively simple, which reduces the doll's appeal and makes it difficult to compete with similar products. Therefore, it is necessary to improve the existing rotation mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a doll with a rotatable outer ring on the bottom surface of its base, which allows for more varied movements of the doll. The technical solution adopted is as follows:

[0006] A doll with a rotatable outer ring on its base includes a base and a body shell. The body shell includes a lower body shell assembly and an upper body assembly, which are respectively mounted on the base. A battery, a drive unit, a gear transmission unit, and a rotating device are installed inside the base. The battery is electrically connected to the drive unit, which drives the rotating device to rotate via the gear transmission unit. Multiple rollers are mounted on the bottom surface of the base. The doll is characterized by further including a rotatable outer ring and an outer ring control mechanism. The outer ring control mechanism includes a control gear, a control component, a spring, and a spring base. The base is assembled from an outer ring receiving unit and a large gear positioning unit. The large gear positioning unit is mounted on the top surface of the outer ring receiving unit, and the control gear is mounted on the top surface of the large gear positioning unit. A control groove is formed on the bottom surface of the control gear. The control slot has at least one lifting ramp. A rotatable outer ring is rotatably mounted outside the rotating device inside the outer ring receiving unit and can be vertically lifted and lowered. The top of the rotatable outer ring has a positioning step. A rack extending circumferentially along the outer wall of the rotatable outer ring is provided. The control component includes a controlled ring and at least one controlled rod. The controlled ring is located inside the outer ring receiving unit and is fitted onto the positioning step. The bottom end of the controlled rod is connected to the controlled ring. The top end of the controlled rod passes through the top surface of the outer ring receiving unit from bottom to top and is inserted into the control slot on the bottom surface of the control gear. A spring base is mounted on the top surface of the inner cavity of the outer ring receiving unit and the spring base restricts the spring between the spring base and the positioning step. When the controlled rod abuts against the top of the lifting ramp, the rack on the outer wall of the rotatable outer ring meshes with a gear of the gear transmission unit. In other words, when the controlled rod is in a position within the control slot without a ramp, the rotatable outer ring is at its highest point under the force of the spring. The rack on its outer wall does not mesh with a gear in the gear transmission unit, and the rotating mechanism drives the doll's movement. When the ramp in the control slot presses against the controlled rod and pushes it downwards, the controlled ring overcomes the spring force and pushes the rotatable outer ring to its lowest point (at this point, the base is suspended, and the rotating mechanism cannot contact the ground and is ineffective). The rack on its outer wall then meshes with a gear in the gear transmission unit, and the rotatable outer ring drives the doll's rotation. This results in two different modes of doll movement: one is the rotating mechanism driving the doll's movement, and the other is the outer ring driving the doll's rotation. These alternating movements create more variety in the doll's motion.

[0007] In a preferred embodiment, an upper body swing mechanism is installed on the base, an upper body component is installed on the upper body swing mechanism, the upper body swing mechanism is connected to a gear transmission unit, and the upper body swing mechanism drives the upper body component to swing.

[0008] The beneficial effect of this utility model compared with the prior art is that, because it is equipped with a rotatable outer ring and an outer ring control mechanism, the lifting and rotation of the rotatable outer ring are controlled by the outer ring control mechanism. Therefore, the movement of the doll is in two different ways: one is that the rotating device drives the doll to move, and the other is that the outer ring drives the doll to rotate. They alternate, making the movement of the doll more varied, thereby greatly enhancing the doll's attractiveness. Attached Figure Description

[0020] like Figure 1-11As shown, in one embodiment of this application, the base has a rotatable outer ring on its bottom surface, including a base 1 and a body shell 2. The body shell 2 includes a lower body shell assembly 201 and an upper body assembly 202. The lower body shell assembly 201 and the upper body assembly 202 are respectively mounted on the base 1. A battery (not shown), a drive unit 3, a gear transmission unit 4 and a rotating device 5 are installed inside the base 1. The battery is electrically connected to the drive unit 3. The drive unit 3 drives the rotating device 5 to rotate through the gear transmission unit 4. Multiple rollers 6 are installed on the bottom surface of the base 1. The doll also includes a rotatable outer ring 7 and an outer ring control mechanism 8. The outer ring control mechanism 8 includes a control gear 801, a control component 802, a spring 803, and a spring base 804. The base 1 is assembled from an outer ring receiving unit 101 and a gear positioning unit 102. The gear positioning unit 102 is installed on the top surface of the outer ring receiving unit 101, and the control gear 801 is installed on the top surface of the gear positioning unit 102. The bottom surface of the control gear 801 has a control groove 8011, and the control groove 8011 has at least one lifting ramp 8012. The rotatable outer ring 7 is rotatably disposed outside the rotating device 5 inside the outer ring receiving unit 101 and can be vertically lifted and lowered. The top of the rotatable outer ring 7 has a positioning step 701, and the outer wall of the rotatable outer ring 7 has a rack 702 extending circumferentially along the outer wall. The control component 802 includes a... The control ring 8021 and at least one controlled rod 8022 are provided. The controlled ring 8021 is disposed inside the outer ring receiving unit 101 and sleeved on the positioning step 701. The bottom end of the controlled rod 8022 is connected to the controlled ring 8021. The top end of the controlled rod 8022 passes through the top surface of the outer ring receiving unit 101 from bottom to top and is inserted into the control groove 8011 on the bottom surface of the control gear 801. The spring base 804 (using fasteners) is installed on the top surface of the inner cavity of the outer ring receiving unit 101 and the spring base 804 restricts the spring 803 between the spring base 804 and the positioning step 701 (that is, the two ends of the spring 803 abut against the inner bottom surface of the positioning step 701 and the spring base 804, respectively). When the controlled rod 8022 abuts against the top of the lifting ramp 8012, the rack 702 on the outer side wall of the rotatable outer ring 7 meshes with a gear of the gear transmission unit 4. In other words, when the controlled rod 8022 is in a position within the control groove 8011 where there is no lifting ramp 8012, under the action of the spring 803, the rotatable outer ring 7 is at its highest point, and the rack 702 on its outer side wall will not mesh with a gear of the gear transmission unit 4, and the rotating device 5 drives the doll to move; when the lifting ramp 8012 in the control groove 8011 abuts against the controlled rod 8022 and pushes the controlled rod 8022 downward, the controlled ring 8021 overcomes the action of the spring 803 and pushes the rotatable outer ring 7 to its lowest point (at this time, the base 1 is suspended, the rotating device 5 cannot contact the ground and has no effect), the rack 702 on its outer side wall meshes with a gear of the gear transmission unit 4, and the rotatable outer ring 7 drives the doll to rotate.This allows the doll to move in two different ways: one is through the rotating device 5, and the other is through the outer ring, which alternates to create more variations in the doll's movement. There are two lifting ramps 8012, evenly distributed around the circumference of the control groove 8011. In this embodiment, there are two controlled rods 8022, evenly distributed around the circumference of the controlled ring 8021.

[0021] like Figure 11 As shown, in an alternative embodiment, the control element 802 further includes at least one limiting rod 8023. The bottom end of the limiting rod 8023 is connected to the controlled ring 8021, and the top end of the limiting rod 8023 abuts against the top surface of the inner cavity of the outer ring receiving unit 101. In this embodiment, there are two limiting rods 8023, which are evenly distributed along the circumference of the controlled ring 8021.

[0022] In an alternative embodiment, the upper body component 202 is fixed to the base 1, and the doll also includes two wing components 9, which are respectively fixed to the upper body component 202. In this design, the upper body of the doll cannot move, and the two wing components 9 also cannot move. This embodiment is similar to... Figure 1-10 The difference in the embodiment shown is that the upper body component 202 and the two wing components 9 do not swing.

[0023] like Figure 3 , 4 As shown in Figure 6, in one alternative embodiment, an upper body swing mechanism 10 is mounted on the base 1, and an upper body component 202 is mounted on the upper body swing mechanism 10. The upper body swing mechanism 10 is connected to a control gear 801, and the upper body swing mechanism 10 drives the upper body component 202 to swing. In this embodiment, the upper body swing mechanism 10 utilizes the power provided by the control gear 801 and uses a mechanical linkage structure to drive the upper body component 202 to swing, making full use of the existing structure, reducing the number of parts and the space occupied, and effectively saving costs. In other alternative embodiments, the upper body swing mechanism 10 can also be connected to a gear transmission unit 4.

[0024] like Figure 3 , 4As shown in Figure 6, in one alternative embodiment, the doll further includes two wing assemblies 9, and a wing swing mechanism 11 is mounted on the upper body swing mechanism 10. The two wing assemblies 9 are respectively mounted on the wing swing mechanism 11, and the upper body swing mechanism 10 drives the two wing assemblies 9 to swing through the wing swing mechanism 11. In this embodiment, because the swinging motion of the wing assemblies 9 is similar to the swinging motion of the upper body assembly 202, the wing swing mechanism 11 can utilize the power provided by the upper body swing mechanism 10. This is also to make full use of the existing structure, reduce the number of parts and the space occupied, and effectively save costs. In other alternative embodiments, the two wing assemblies 9 can also be connected to the gear transmission unit 4 respectively.

[0025] like Figure 5-7 As shown, in one alternative embodiment, the drive unit 3 is a motor.

[0026] During operation, the motor transmits power to the gear transmission unit 4. The gear transmission unit 4 drives the rotating device 5 to rotate, and simultaneously transmits power to the outer ring control mechanism 8. The outer ring control mechanism 8 controls the raising and lowering of the rotatable outer ring 7. This allows the doll to move in two different ways: one is that the rotating device 5 drives the doll to move, and the other is that the outer ring drives the doll to rotate. These two processes alternate, giving the doll's movement more variety.

[0027] The upper body swing mechanism 10 drives the upper body component 202 to swing, and the wing swing mechanism 11 drives the two wing components 9 to swing.

[0028] Furthermore, it should be noted that the names of the various parts of the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, they should all fall within the protection scope of this utility model.
