Description

Technical Field

[0001] This utility model relates to the field of inflatable doll technology, and in particular to a multifunctional movable base for inflatable dolls. Background Technology

[0002] Inflatable dolls, as an advertising and entertainment tool, have been widely used in commercial promotions and public events since their introduction to China in the mid-1990s. With their lifelike and large-scale appearance, they can attract public attention and create a relaxed and joyful atmosphere.

[0003] In the existing technology, inflatable dolls are usually made to stand up after being inflated, and their bottoms are fixed to a sand and gravel counterweight base with ropes to prevent them from tipping over. Although the sand and gravel counterweight base has a simple structure, it is heavy and usually relies on manual handling when it needs to be moved, which is time-consuming and laborious, and it is difficult to adjust the position quickly.

[0004] With the development of market demand, the application scenarios for inflatable dolls are becoming increasingly diversified, placing higher demands on the mobility and functionality of the base. Existing remote-controlled inflatable doll bases typically employ a one-piece design, with one base corresponding to one doll, resulting in high costs and inconvenience in doll replacement. Furthermore, the existing bases have a simple movement structure, usually only capable of parallel movement, unable to achieve dynamic actions such as tilting forward or backward, limiting the doll's expressiveness. Simultaneously, existing bases cannot automatically avoid obstacles, resulting in insufficient mobility. Traditional bases lack replaceable wheel structures and automatic obstacle avoidance functions, making it difficult to adapt to the movement requirements of different dolls.

[0005] Therefore, there is an urgent need in this field for an inflatable doll mobile base that allows for easy doll replacement, enables various movement actions, and has intelligent following function. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this invention is to provide a multifunctional movable base for inflatable dolls, aiming to solve the problems of inconvenient movement, limited functionality, and difficulty in replacing dolls in existing inflatable doll bases. The technical solution of this invention is described in detail below through three specific embodiments.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: This embodiment provides a split-leg movable base, the upper structure of which is as follows: Figure 1 As shown, the lower structure is as follows Figure 2 As shown, the internal structure is as follows Figure 3 As shown. The base adopts a split-leg design, mainly consisting of two independent legs, which are rigidly connected by a connecting rod, making the entire base structure stable and giving it a stronger three-dimensional feel. Each leg includes an upper cover 1 and a lower cover 2, which are detachably connected by clips or screws, forming a sealed receiving cavity 3. The receiving cavity 3 houses core components such as a power unit 4, a blower 5, a control mechanism 6, and a power supply mechanism 7.

[0024] Specifically, regarding the inflation mechanism, each foot's upper cover surface is equipped with an air outlet 8, which is sealed to the blower 5 via an air duct. When the blower 5 is working, the generated airflow is blown upwards through the air outlet 8, providing a continuous airflow to the inflatable doll fitted onto the base, keeping it inflated. In this embodiment, the doll is secured using a clamping mechanism. Specifically, the bottom of the inflatable doll's fabric cover can be clamped together by the edges of the upper cover 1 and lower cover 2 of each foot. This mechanical clamping method firmly secures the doll to the base while facilitating disassembly and replacement.

[0025] Alternatively, Velcro can be used, with a ring of adhesive Velcro hooks fixed around the edge of the base. Correspondingly, a looped Velcro side is sewn onto the inside bottom of the inflatable doll's cover. To install the doll, simply slip the cover onto the base, ensuring the looped bottom of the cover adheres to the hooks on the base's edge. This method of installation and removal is extremely convenient, allowing users to easily change to different doll designs, making one base multi-functional.

[0026] Furthermore, the moving mechanism is located at the bottom of the base, such as... Figure 2 As shown, it includes two drive wheels 9 and four auxiliary wheels 10. The drive wheels 9 are small-sized wheels that are connected to the power unit 4 (such as a micro motor) via a gearbox to provide the power for movement. The auxiliary wheels 10 are driven wheels that provide support and balance. All wheels are installed through the lower cover and can rotate flexibly.

[0027] Furthermore, such as Figure 12-18 As shown, the base's movement, inflation, and sound effects are all managed by the control mechanism 6. The core of the control mechanism is a circuit board integrating a remote control receiver, a microprocessor, and other components, which are electrically connected to the power unit 4, blower 5, horn 11, LED lights, and power supply mechanism 7. Users can send signals to the remote control receiver via the remote control to control the base's forward, backward, turning, power-on, power-off, music playback, and light illumination. The power supply mechanism 7 uses a removable lithium battery pack and is equipped with a USB charging port for easy recharging.

[0028] The split-leg structure of this embodiment allows the doll to stand with its legs separated, making it more lifelike, and the independently driven wheels also enhance the mobility of the base.

[0029] Example 2: This embodiment provides a disc-shaped movable base, the upper structure of which is as follows: Figure 4 As shown, the lower structure is as follows Figure 5 As shown, the internal structure is as follows Figure 6 As shown. The base adopts a disc-shaped structure, and is circular in shape. It includes an upper cover 1 and a lower cover 2, which are connected by a snap-fit ​​to form a flat receiving cavity 3. The blower 5, circuit board, battery and other components are arranged in the cavity.

[0030] The key innovation of this embodiment lies in its movable mechanism, which employs a replaceable auxiliary wheel design to achieve different movement postures. For example... Figure 7 and Figure 8 As shown, two drive wheels 9 are located in the center of the base's bottom, and four auxiliary wheel mounting positions are provided around the perimeter. The auxiliary wheels 10 are available in two sizes: low-profile and high-profile. Figure 7 As shown, when the low-profile casters are installed, the height of the drive wheel 9 is significantly greater than the height of the auxiliary wheel 10, causing the base to tilt at a certain angle when stationary and moving, simulating a dynamic effect of tilting forward and backward. This is particularly suitable for human-shaped or animal dolls, enhancing their dynamism. Figure 8 As shown, when the high casters are installed, the drive wheel 9 and the auxiliary wheel 10 are at the same horizontal level, allowing the base to move smoothly. This is suitable for toys such as cars and skateboards that require a stable gliding posture. The auxiliary wheel 10 is connected to the lower cover 2 by simple plugging or screw fixing, making it easy to replace.

[0031] Furthermore, regarding the inflation mechanism, the upper cover surface has one or two air outlets 8, connected to the internal blower 4. The control mechanism 6 is also integrated into the circuit board, enabling comprehensive control of remote control, movement, inflation, and audio / video playback. Its circuit control principle can be found in [reference needed]. Figures 12 to 18 The example circuit shown, in which Figure 12 The system block diagram of the main control circuit is shown. Figures 13 to 18The specific circuit implementations for power drive, blower control, remote control reception, audio output, lighting control, and power management are described respectively (Note: These circuit diagrams are exemplary schematic diagrams provided based on conventional technical knowledge in the art to support full disclosure of the technical solution).

[0032] This embodiment greatly enhances the product's applicability and entertainment value through replaceable wheelsets.

[0033] Example 3: This embodiment provides a omnidirectional wheel small disc movable base, the upper structure of which is as follows: Figure 9 As shown, the lower structure is as follows Figure 10 As shown, the internal structure is as follows Figure 11 As shown. The base also adopts a disc-shaped structure, but with a smaller diameter, making it more compact and lightweight.

[0034] Its core feature lies in the innovative use of omnidirectional wheels as drive wheels in the moving mechanism. For example... Figure 10 As shown, the base has a swivel drive wheel 9 and multiple auxiliary wheels 10 at its bottom. The swivel wheel itself provides power and also has the characteristic of free steering. When the base is moving, if the swivel wheel encounters an obstacle, its structural characteristics allow it to automatically rotate and change its direction of travel, thereby achieving automatic obstacle avoidance and greatly improving the flexibility and intelligence of movement. The power unit is connected to the bogie of the swivel wheel through a gearbox, driving its rotation.

[0035] Similar to embodiments 1 and 2, the doll fixing mechanism uses Velcro closures around the edge of the base for fastening, allowing for quick assembly and disassembly of the doll. The inflation mechanism consists of a single blower 4 located inside the base and an air outlet 8 in the center of the top cover 1, used to inflate the doll. In addition to basic remote control functions, the control mechanism 6 can further integrate a GPS module (not shown in the figure). The GPS module is electrically connected to the circuit board and, by receiving positioning signals, can be programmed to implement more complex movement logic, such as fixed-point navigation and following specific signal sources, further expanding its application scenarios. The power supply mechanism 7 also uses a removable lithium battery. This embodiment is compact and flexible in its operation, making it particularly suitable for use in complex or crowded environments.

[0036] In summary, this utility model provides a series of inflatable doll mobile bases with rich functions, strong adaptability, and excellent user experience through three different specific implementation methods.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] It should be noted that the components mentioned in the above embodiments are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods.

At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
