Description

Technical Field

[0001] This utility model relates to the field of night light technology, specifically to a multi-door fan device that opens and closes sequentially and its toy. Background Technology

[0002] In the toy manufacturing industry, toys with door-like structures have always been popular with children, such as dollhouses, castle models, and magic boxes. Currently, these toys generally use a single door structure; even double-door designs are simply combinations of two independent doors. Each door moves synchronously during opening and closing, lacking dynamic variation and a sense of depth.

[0003] This traditional single-door structure has significant limitations. First, the opening and closing process of the door is too monotonous, lacking drama and surprise, and failing to sustain children's attention. Second, all the doors opening and closing simultaneously obscure or expose the interior space while in motion, failing to create a gradual display effect and reducing the toy's fun and interactivity. Furthermore, in toy designs with limited space, the simultaneous opening of multiple doors requires a large activity space, limiting the flexibility of the toy design.

[0004] While some high-end toys attempt to achieve special opening and closing effects using complex transmission mechanisms, these designs are often structurally complex, costly, and unreliable, making them unsuitable for widespread application in mass-market toys. Therefore, there is an urgent need for a novel door structure design that can add more fun and appeal to toy products while remaining cost-effective. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems and shortcomings by providing a multi-door device that opens and closes sequentially, effectively solving the problems of monotonous, lacking in layering and fun, in the opening and closing process of existing toy doors; furthermore, it provides a toy that uses this multi-door device to add more fun and appeal to the toy.

[0006] The technical solution of this utility model is implemented as follows: This utility model discloses a multi-door device that opens and closes sequentially, comprising a door structure and a drive structure for driving the door structure to open and close. The door structure includes one active door leaf and at least one passive door leaf. The active door leaf is provided with a first traction member, and the passive door leaf is correspondingly provided with a second traction member that cooperates with the first traction member. The door structure has an open state and a closed state. The drive structure includes a drive source, a transmission mechanism, an output end, and a control source. The output end is connected to the active door leaf to drive its movement. The transmission mechanism is connected between the drive source and the output end. The control source is used to control the start or stop of the drive source. When the door structure is in the closed state, the control source is activated to start the drive source. The output terminal drives the active door leaf to move from the closed state to the open state. After the active door leaf moves a certain distance, the first traction member pulls the second traction member to drive the driven door leaf to move together to the open state. When the door structure is in the open state, the control source is activated to start the drive source. The output terminal drives the active door leaf to move from the open state to the closed state. After the active door leaf moves a certain distance, the first traction member pulls the second traction member to drive the driven door leaf to move together to the closed state.

[0007] In some embodiments, the first traction member is a traction block fixed to the surface of the active door leaf facing the driven door leaf, and the second traction member is a corresponding slide groove disposed on the surface of the driven door leaf facing the active door leaf. The traction block extends into the slide groove and can slide in the slide groove. When the door structure is in the closed state, the traction block is located at the first end of the slide groove, and when the active door leaf moves to the open state, the traction block moves towards the second end of the slide groove until the traction block abuts the second end, at which point the traction block drives the slide groove and the driven door leaf to move together with the active door leaf. When the door structure is in the open state, the traction block is located at the second end of the slide groove, and when the active door leaf moves to the closed state, the traction block moves towards the first end of the slide groove until the traction block abuts the first end, at which point the traction block drives the slide groove and the driven door leaf to move together with the active door leaf.

[0008] Furthermore, the slide is replaced by two protruding edges spaced apart on the surface of the driven door facing the driving door, and the traction block moves within the range between these two protruding edges.

[0009] In some embodiments, the door structure includes an active door leaf, at least one first passive door leaf and a second passive door leaf, the first passive door leaf having a first traction member and a second traction member, and the second passive door leaf having a second traction member; the second traction member of the first passive door leaf cooperates with the first traction member of the active door leaf or the first traction member of another adjacent first passive door leaf; the first traction member of the first passive door leaf cooperates with the second traction member of the second passive door leaf or the second traction member of another adjacent first passive door leaf.

[0010] In some embodiments, the transmission mechanism includes a clutch mechanism, which has an engaged state and an disengaged state. When the drive source drives the transmission mechanism, the clutch mechanism is in the engaged state to drive the door structure to open and close normally. When the drive source is in the non-starting state and an external force is applied to the door structure, the clutch mechanism is in the disengaged state, and the door structure can move under the action of the external force.

[0011] In some embodiments, the sequentially opening and closing multi-door device includes two opposing door structures, each of which is driven individually by a drive structure, or both door structures are driven simultaneously by a single drive structure.

[0012] Furthermore, when both door structures are driven simultaneously by one of the drive structures, the transmission mechanism of the drive structure is provided with two output gears that are respectively meshed with the two ends of the rotating shaft gear of the drive source. The transmission mechanism transmits power to the active door panels of the two door structures respectively, and the transmission ratio is the same, so as to realize that the two door structures move in opposite directions at the same speed.

[0013] In some embodiments, the door structure can be swung, moved, or folded.

[0014] This utility model also provides a toy, characterized in that it includes the multi-door device that opens and closes sequentially, a base, and a main body disposed on the base. The door structure of the multi-door device is movably connected to the base. When the door structure is in the closed state, the main body is covered by the door structure. When the door structure is in the open state, the main body is exposed.

[0015] In some embodiments, the main body is a mirror or a cavity that can accommodate objects, and the base, the main body, and the multi-door assembly together constitute a single form.

[0016] The beneficial effects of this utility model are: (1) This utility model creates a dynamic effect with a sense of layering by designing the sequential opening and closing of the active door leaf and the passive door leaf, which greatly enhances the fun and attractiveness and can better stimulate children's curiosity and desire to explore.

[0017] (2) The phased opening and closing of the door creates a gradual display process, effectively enhancing the dramatic effect and interactive experience of the toy, making each opening and closing full of surprises.

[0018] (3) The simple traction mechanism achieves the complex effect of opening and closing multiple doors in sequence. The structure is reliable and the cost is low. It is particularly suitable for promotion and application in cost-sensitive toy products and has a good market prospect.

[0019] (4) The toy of this utility model has an ingenious structural design through the organic combination of the base, the main body and the multi-door fan device, which can realize the fun display function, make the toy shape changeable, and add more fun and attractiveness.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The following description, in conjunction with the accompanying drawings, describes the multi-door fan device and toy of this utility model that opens and closes sequentially.

[0028] In the toy manufacturing industry, creating attractive and engaging opening and closing structures has always been a goal pursued by designers. Traditional toy door structures often employ a single door or a multi-door design that opens and closes simultaneously, which tends to be monotonous in terms of visual effects and interactive experience. To overcome this limitation, this invention develops a multi-door device 200 with a sequential opening and closing function. This device achieves the visual effect of the doors opening and closing in stages through a clever mechanical structure, bringing a completely new interactive experience to toy products.

[0029] like Figure 1 and Figure 2 As shown, in its basic structure, the multi-door device 200 that opens and closes sequentially mainly comprises two core parts: a door structure 1 and a drive structure 2. The door structure 1 can be one or more, and includes one active door leaf 11 and at least one passive door leaf 12. Power is transmitted between them through a traction mechanism such as a first traction member 3 and a second traction member 4. The active door leaf 11 is directly connected to the drive structure 2 and serves as the power input for the entire door structure 1; the passive door leaf 12 is linked to the active door leaf 11 through the traction mechanism, and its movement always lags behind the active door leaf 11. This master-slave design allows the door leaves to create a staggered visual effect during opening and closing, greatly enhancing the toy's appeal.

[0030] There are various ways to implement the first traction component 3 and the second traction component 4, among which the preferred method is the cooperation between the traction block and the slide groove. In actual manufacturing, such as Figure 3As shown, the first traction member 3 is typically in the form of a traction block, made of wear-resistant engineering plastic or metal. Its shape can be designed as cylindrical, rectangular, or other suitable shapes as needed. The traction block is fixed on the surface of the active door leaf 11 facing the driven door leaf 12. Its installation position needs to be precisely calculated to ensure a good fit with the second traction member 4 on the driven door leaf 12. The second traction member 4 corresponds to a slide groove, which is opened at the corresponding position on the surface of the driven door leaf 12 facing the active door leaf 11. Its length directly determines the travel distance of the active door leaf 11 moving alone. The slide groove has two key positions: a first end 41 and a second end 42. When the door structure 1 is in the closed state, the traction block is located at the first end 41 of the slide groove; when the door structure 1 is in the open state, the traction block is located at the second end 42 of the slide groove. When the active door leaf 11 starts to move, the traction block first slides freely from one end to the other in the slide groove, at which time the driven door leaf 12 remains stationary; only when the traction block slides to the end of the slide groove will it begin to push the driven door leaf 12 to move together. This simple mechanical mechanism achieves complex sequential opening and closing effects, and its low manufacturing cost makes it ideal for the large-scale production of toy products.

[0031] Besides using a combination of a traction block and a sliding track, the sliding track can be replaced with two protruding edges spaced apart on the surface of the driven door leaf 12 facing the driving door leaf 11. The traction block moves within the range between these two protruding edges. This design makes the driving door leaf 11 and the driven door leaf 12 less compact, but it still achieves the traction effect. Furthermore, the positions of the traction block and the sliding track, or the traction block and the protruding edges, can be interchanged. That is, the first traction member 3 can be a sliding track or a protruding edge, while the second traction member 4 is a traction block.

[0032] The movement of the door panels can be flexibly selected according to the specific design requirements of the toy. Common movement methods include swinging, moving, and folding. Swinging is the most traditional form of door opening and closing, using hinges or pivots to achieve the arc-shaped swing of the door panels. The advantages of this method are its simple structure and high reliability. Figure 1 The example shown uses a swing mechanism. The moving mechanism involves the door sliding linearly along a guide rail, which effectively saves space and is particularly suitable for toy designs with limited space. The folding mechanism uses multiple joints to connect and open the door, achieving a very compact storage effect. Different movement mechanisms can be used in conjunction with the same traction mechanism, greatly enhancing the applicability and flexibility of this invention.

[0033] For complex structures requiring more door panels, a multi-stage chain drive design can be adopted, comprising at least one first driven door panel 13 and one second driven door panel 14. In this design, a first driven door panel 13 with dual functions is introduced. The first driven door panel 13 is equipped with both a first traction member 3 and a second traction member 4, serving as both a driven member of the preceding door panel and an active member of the following door panel. The second driven door panel 14, as the final door panel, only requires a second traction member 4. The second traction member 4 of the first driven door panel 13 cooperates with the first traction member 3 of the active door panel 11 or with the first traction member 3 of another adjacent first driven door panel 13; the first traction member 3 of the first driven door panel 13 cooperates with the second traction member 4 of the second driven door panel 14 or with the second traction member 4 of another adjacent first driven door panel 13. This chain drive structure allows for the sequential opening and closing of three or more door panels, creating a richer visual effect. With each additional stage of transmission, the rhythm of the door opening becomes more pronounced, and this progressive display method greatly enhances the drama and appeal of the toy.

[0034] The design of drive structure 2 needs to balance functionality and safety. For example... Figure 4 As shown, a drive source 21 is typically used in conjunction with a transmission mechanism 22. The drive source 21 is usually a small DC motor, which transmits power to the active door leaf 11 through the output terminal 23. The control source 24 is used to control the start or stop of the drive source 21, and can be a simple switch or a complex remote control or remote sensing system. To ensure safety, a special clutch mechanism 25 is provided in the transmission mechanism 22, such as... Figure 5 As shown, the clutch mechanism 25 has two operating modes: engaged and disengaged. When the drive source 21 is working normally, the clutch mechanism 25 is in the engaged state, ensuring reliable power transmission; when the drive source 21 is not in the activated state and an external force is applied to the door structure 1, the clutch mechanism 25 is in the disengaged state, allowing the door structure 1 to move under the action of external force, thus preventing damage to the transmission mechanism 22 and the drive source 21 while ensuring safety. This design is particularly important because the users of toy products are often children, and safety and durability must be the top priorities.

[0035] like Figure 6 and Figure 7As shown, the door structure 1 of this utility model can also include two or more. For example, in applications requiring symmetrical opening and closing, it can include two opposing door structures 1. In terms of driving, each of the two door structures 1 can be driven individually by a driving structure 2, or both door structures 1 can be driven simultaneously by a single driving structure 2. When both door structures 1 are driven simultaneously by a single driving structure 2, a design scheme using a single driving source 21 in conjunction with a symmetrical transmission mechanism 22 is adopted. This design achieves precise, same-speed, opposite-direction movement of the two door structures 1 by setting identical output gears 221 at both ends of the shaft gear of the driving source 21, while ensuring that the transmission mechanisms 22 connected to the two door structures 1 have exactly the same transmission ratio. The symmetrically opening and closing door panels not only move in a coordinated and aesthetically pleasing manner but also create a unique visual effect. This design ensures motion accuracy while simplifying the control system, achieving a good balance between cost and performance.

[0036] This utility model also provides a toy 100, which integrates a multi-door device 200 into the toy 100. Considering the overall structural coordination and functionality, the toy 100, in addition to the sequentially opening and closing multi-door device 200, also includes a base 5 and a main body 6 mounted on the base 5. The base 5 provides a stable support foundation for the entire device, and its shape can be specially designed according to the toy's theme. The door structures 1 of the multi-door device 200 are movably connected to the base 5. The main body 6 can be a functional component, such as a mirror, storage cavity, or electronic interactive device. By controlling the rhythm and sequence of the door opening, various interesting interactive games can be designed. For example, when the door structure 1 is closed, the main body 6 is obscured by the door structure 1; when the door structure 1 is open, the main body 6 is exposed. Furthermore, different opening speeds can be set, or sound and light effects can be combined to create a richer sensory experience. The base 5, the main body 6, and the multi-door device 200 can together form a single shape, thereby improving the overall coordination and aesthetics of the toy 100.

[0037] The following is a detailed description of specific embodiments.

[0038] Example 1: Basic Double-Door Structure like Figures 1 to 3 As shown, this embodiment includes a door structure 1 and a drive structure 2. The door structure 1 includes an active door leaf 11 and a driven door leaf 12. The first traction member 3 of the active door leaf 11 is a traction block, and the second traction member 4 of the driven door leaf 12 is a sliding groove. The door structure 1 has a sequential opening and closing device for the two door leaves in an open and closed state. The active door leaf 11 is mounted on the right side of the door frame via a stainless steel pivot, and the driven door leaf 12 is connected to the same pivot and located on the left side of the door frame. The shapes of the two door leaves can be as follows: Figure 1The shape can be an icicle cone, or other shapes such as rectangles or fan shapes. The two door panels can be the same size or one large and one small.

[0039] like Figure 2 As shown, a specially designed traction block, serving as the first traction element 3, is provided at the connection between the active door leaf 11 and the pivot. This traction block is firmly fixed to the active door leaf 11 using ultrasonic welding and is fan-shaped. A precisely curved groove, serving as the second traction element 4, is provided at the corresponding position of the driven door leaf 12. The groove is longer than the length of the traction block and slightly wider than the width of the traction block. It is injection molded to ensure a smooth surface, allowing the traction block to slide smoothly. Furthermore, buffer structures can be provided at both the first end 41 and the second end 42 of the groove to reduce collision noise.

[0040] like Figure 4 As shown, the drive structure 2 in this embodiment includes a drive source 21, a transmission mechanism 22, an output terminal 23, and a control source 24. The drive source 21 is a DC geared motor, which transmits power to the output terminal 23 through a set of reduction gears in the transmission mechanism 22. The output terminal 23 is a stainless steel rotating shaft connected to the active door leaf 11. The control source 24 can be a miniature toggle switch, which can be installed on the toy 100.

[0041] When door structure 1 is in the closed state, the control source 24 activates the drive source 21, and the output end 23 drives the active door leaf 11 from the closed state to the open state. In the first 2 seconds, the active door leaf 11 rotates 40 degrees independently. During this time, the traction block moves from the first end 41 to the second end 42 in the slide groove, but the driven door leaf 12 remains closed. When the active door leaf 11 rotates to the 40-degree position, the traction block abuts against the second end 42 of the slide groove, starting to pull the second traction member 4 to drive the driven door leaf 12 to the open state. In the next 3 seconds, both door leaves rotate synchronously to the fully open position. When the door structure 1 needs to be closed, the control source 24 starts the drive source 21, and the output end 23 drives the active door leaf 11 to move from the open state to the closed state. After the active door leaf 11 moves a certain distance, the traction block moves from the second end 42 to the first end 41 in the slide rail until the traction block touches the first end 41. When the traction block touches the first end 41, the traction block drives the slide rail and the driven door leaf 12 to move together with the active door leaf 11 to complete the closing process.

[0042] The sequential opening and closing of the door panels in this embodiment adds unexpected fun to the toy. Children are often fascinated by this "dancing door," repeatedly operating the switch and observing the amazing effect of the door panels moving in stages. Compared to traditional synchronous door opening, this design extends the duration of the opening process, creating a stronger sense of anticipation and surprise. At the same time, because the movement is performed in stages, the torque required for instantaneous start-up is reduced, making the motor work more smoothly.

[0043] Example 2: Symmetrical Six-Door Structure like Figure 6 and Figure 7 As shown, this embodiment illustrates a more complex symmetrical multi-door assembly 200, which comprises two completely symmetrical door structures 1 located on either side of a door frame. Each door structure 1 consists of three door leaves: an active door leaf 11, a first driven door leaf 13, and a second driven door leaf 14.

[0044] In this embodiment, the door panels are still shaped like icicle cones. The active door panel 11 is the smallest and has a shaft hole for connection to a stainless steel rotating shaft serving as the output end 23. The first driven door panel 13 is slightly larger than the active door panel 11, and its second traction member 4 is connected to the first traction member 3 of the active door panel 11. This traction mechanism includes a cylindrical traction block and an arc-shaped slide groove with a length of 15mm. The second driven door panel 14 is the largest, and its second traction member 4 is connected to the first traction member 3 of the first driven door panel 13. The slide groove of the second traction mechanism has a length of 10mm. After the three door panels are connected, the active door panel 11 is at the front end and the second driven door panel 14 is at the rear end.

[0045] This embodiment uses a single drive structure 2 to simultaneously drive the multiple door panels of two door structures 1, that is, it uses a single drive source 21, which can be a micro DC motor, in conjunction with a self-developed symmetrical gear transmission mechanism 22. Figure 7 As shown, the drive source 21 is located in the middle of the two door structures 1. The gear set of the transmission mechanism 22 includes three reduction gears 222. The first of these three reduction gears 222 meshes with the shaft gear of the drive source 21. The other two reduction gears 222 mesh and engage in successive reduction gear engagements. The two output gears 221 are respectively engaged with both ends of the last reduction gear 222. Then, one side meshes with a gear of the same size as the output gear 221 to change the direction of rotation. Next, a clutch mechanism 25 is connected in sequence. After the clutch mechanism 25, a transmission gear 223 is engaged as needed. Figure 7 In this example, two transmission gears 223 are connected after the clutch mechanism 25. The last transmission gear 223 is connected to the output end 23 to drive the active door leaf 11 to rotate. The transmission mechanism 22 transmits power to the active door leaves 11 of the two door structures 1 respectively, and the transmission ratio is the same to achieve the same speed and opposite movement of the two door structures 1. The entire transmission system is installed in the gearbox 26 to ensure the stability and accuracy of operation.

[0046] In this embodiment, a clutch mechanism 25 is specially provided in the transmission mechanism 22. The clutch mechanism 25 adopts the form of two gear end face clutch engagement. The two gears are coaxially designed, and the end face of the first gear 251 is provided with a recess. The bottom surface of the recess is provided with a textured surface 253. The second gear 252 can extend into the recess, and the end face of the extended part is provided with a protrusion 254 corresponding to the textured surface 253. The protrusion 254 engages with the recess of the textured surface 253. The second gear 252 has a tendency to move towards the first gear 251 to ensure that the protrusion 254 and the recess of the textured surface 253 have a certain engagement force. This tendency force can be realized by a spring. When the drive source 21 drives the transmission mechanism 22, the clutch mechanism 25 is engaged, meaning the protrusion 254 engages with the recess, allowing the door structure 1 to open and close normally. When the drive source 21 is not in operation and an external force is applied to the door structure 1, the clutch mechanism 25 is disengaged, causing the protrusion 254 to disengage from the recess, allowing the door structure 1 to move under the influence of the external force. This safety design ensures the reliability of the toy during use and prevents damage to the transmission mechanism 22 and drive source 21 due to unexpected resistance.

[0047] When the motor starts, the two active door panels 11 on the left and right begin to move synchronously in opposite directions. In the first 1.5 seconds, the active door panel 11 rotates 40 degrees, while the first driven door panel 13 remains stationary. When the active door panel 11 reaches the 40-degree position, the first traction member 3 pulls the second traction member 4, and the first driven door panel 13 begins to move. After another second, the first driven door panel 13 rotates 35 degrees, and its first traction member 3 pulls the second traction member 4 of the second driven door panel 14, causing the second driven door panel 14 to join the movement. Finally, all six door panels fully unfold in three stages, forming a symmetrical fan-shaped pattern. Throughout the entire process, the clutch mechanism 25 remains engaged to ensure reliable power transmission.

[0048] The visual effect of this embodiment is quite stunning. The six doors bloom sequentially like flower petals, and the symmetrical layout enhances the visual appeal. The single drive source 21 ensures precise synchronization of movement while effectively controlling costs. The clutch mechanism 25 design increases the product's safety and lifespan. This design is particularly suitable for mid-to-high-end toy models, showcasing intricate mechanical structures while providing a satisfying interactive experience.

[0049] Example 3: Independently controlled eight-door structure In this embodiment, the door structure 1 also consists of two opposing doors, but each door structure 1 contains four door panels. This complex device is used in a futuristic science fiction-themed toy. The entire device is divided into two completely independent parts, left and right, each containing four door panels of the door structure 1: one active door panel 11, two first driven door panels 13, and one second driven door panel 14; and a drive structure 2. This three-stage transmission chain creates an extremely rich sense of layering.

[0050] Each door leaf can be made of aerospace-grade aluminum alloy with an anodized surface, giving it a metallic texture. The active door leaf 11 and each passive door leaf 12 feature a gradient size design to enhance the visual depth.

[0051] The traction mechanism is made of self-lubricating nylon and features a streamlined shape to reduce motion resistance. The chute is fitted with a wear-resistant PTFE bushing and an oil reservoir, allowing for periodic lubrication to maintain smooth operation over the long term. The lengths of each chute are precisely calculated, for example, 18mm, 12mm, and 8mm, creating varying motion delays.

[0052] The drive system uses a servo motor with a built-in high-precision encoder, enabling precise control of the door's opening and closing angle and speed. The motor receives control signals via a CAN bus and supports programming for multiple opening and closing modes. The clutch mechanism 25 employs an electromagnetic design, generating magnetic force to engage the clutch when energized and automatically disengaging when de-energized, allowing for manual operation.

[0053] When the device is activated, the left and right door structures 1 can operate independently according to a preset program. For example, the left door structure 1 may begin to unfold first, and the right door structure 1 will begin to move after a 2-second delay. The four doors inside each door structure 1 unfold sequentially in three stages. This multi-layered sequence of movements creates an extremely complex visual effect, as if a sophisticated mechanical device is performing.

[0054] The sequential unfolding of the eight doors in this embodiment is highly dramatic, and independent control allows for countless opening and closing combinations. Precise motion control and a reliable structural design make this embodiment particularly suitable for the high-end, premium toy market, satisfying consumers seeking the ultimate experience.

[0055] Example 4: 100 Ice and Snow Castle Theme Toys like Figures 8 to 10As shown, this embodiment applies the multi-door fan assembly 200 to a dreamy ice and snow castle-themed toy 100. The entire toy 100 is inspired by classic fairy tales, including a door structure 1, a base 5, and a main body 6. The base 5 is designed as a crystal-clear ice and snow castle, made of blue and white materials. The base 5, the main body 6, and the multi-door fan assembly 200 together constitute a complete ice and snow castle design.

[0056] The door structure 1 in this embodiment adopts a unique scissor-type rotating double-opening method. Each door structure 1 includes three door leaves: an active door leaf 11, a first driven door leaf 13, and a second driven door leaf 14. All three door leaves are designed in an icicle-like shape. The specific structural style of the door structure 1 and the corresponding drive structure 2 are the same as in Embodiment 2, so they will not be described again. The slight difference is in the traction mechanism, where the traction block is fan-shaped, the slide is arc-shaped, the length of the slide is longer than the length of the traction block, and the width is slightly larger than the width of the traction block. All door leaf surfaces are specially treated to present a translucent, snow-like effect, and fiber optic light guide strips are embedded inside.

[0057] In this embodiment, the main body 6 is a mirror, located in the middle of the base 5. It is a semi-transparent lens with an ice-like surface treatment, and a light strip is provided behind the mirror. The surface of the lens can be made into an ice crystal texture using an embossing technique, which can both reflect images and produce a unique refractive effect. When the door structure 1 is in the closed state, the main body 6 is blocked by the door structure 1; when the door structure 1 is in the open state, the main body 6 is exposed.

[0058] The clutch mechanism 25 in this embodiment is as follows: Figure 5 As shown, when the drive source 21 drives the transmission mechanism 22, the clutch mechanism 25 is engaged to drive the door structure 1 to open and close normally; when the drive source 21 is not in the starting state and an external force is applied to the door structure 1, the clutch mechanism 25 is disengaged, and the door structure 1 can move under the action of external force. This design ensures both the accuracy of electric operation and the safety of manual operation.

[0059] In this embodiment, the control source 24 is an infrared sensor controller. The control source 24 is set on the base 5 above the main body 6 and faces the front of the toy 100. The control source 24 is covered with a diamond-shaped light-transmitting plastic part 53, which is connected to the corresponding through hole on the base 5.

[0060] To enhance the immersive experience of the ice castle, three semi-transparent, architecturally-tower-like structural elements 51 are installed above the base 5, with lighting devices 52 inside each element. The base 5 also features a sound system. When the doors begin to move, the lighting devices 52, when powered on, emit light through the structural elements 51, creating a fully immersive experience in conjunction with the sound system.

[0061] When toy 100 is activated, soft background music plays first, and the LED lights on the base 5 begin to emit a soft glow. When the player's hand waves in front of control source 24, drive source 21 is activated, and the active door 11 slowly opens, providing only basic lighting effects at this stage. As the first driven door 13 begins to move, the brightness of the LED lights gradually increases and begins to change colors. When the second driven door 14 is fully opened, the mirror is fully exposed, the LED lights reach their brightest state, and a crisp sound is emitted. The entire process lasts for a few seconds, creating a complete magical display sequence.

[0062] This embodiment creates a highly immersive gaming experience through the perfect integration of multimedia elements. The sequential opening of the doors, combined with the meticulously designed ice castle shape and sound and light effects, recreates a magical world from a fairy tale, deeply engaging children's emotions. The clutch mechanism 25 is designed to ensure the product's safety and lifespan, preventing any potential pinching risks and avoiding damage to the transmission mechanism 22 and drive source 21 from external forces. This multi-sensory stimulation not only enhances the entertainment value but also inspires children's imagination and creativity.

[0063] Example 5: Multifunctional Storage Toy This embodiment showcases an exquisite toy that combines display and storage functions. The entire product is designed as a magic treasure chest, including a base 5 as the chest body, a double-door structure 1, and a cavity 6 as the main body. The surface of the chest body is decorated with exquisite embossed patterns and inlaid with imitation gemstone ornaments.

[0064] The door structure 1 employs a smooth sliding opening mechanism, and each door structure 1 contains three door panels. The bottom of the active door panel 11 is equipped with a precision linear guide system, which includes a track and four rollers to ensure smooth and quiet sliding of the door panel. The first driven door panel 13 and the second driven door panel 14 are connected by a concealed traction mechanism. All mechanical structures are cleverly hidden inside the door panels, maintaining a clean and aesthetically pleasing appearance.

[0065] The storage compartment features a partitioned design with six different sized compartments for storing various types of items. A gravity sensor at the bottom of the compartment triggers corresponding electronic sound effects when an item is placed or removed. For example, a crisp bell rings when a lighter item is placed, while a deep chime sounds when a heavier item is placed. This intelligent interactive feature adds a playful element to everyday storage. Illumination devices 52 are positioned around the compartment and automatically illuminate when the door is opened, displaying the items stored inside.

[0066] The drive structure 2 adopts a linear motor drive system. The transmission mechanism 22 includes a ball screw and a linear guide rail, and the output end 23 is directly connected to the active door leaf 11. The control source 24 is a touch-sensitive switch, installed on the front decorative surface of the treasure chest; it can also be a remote control, set independently.

[0067] When the user gently touches the switch or presses the remote control, the active door panel 11 slides smoothly at a preset speed. In the initial sliding phase, only the active door panel 11 moves, while the other door panels remain stationary. After the active door panel 11 slides a certain distance, the first traction member 3 pulls the second traction member 4, and the first driven door panel 13 begins to move. After sliding a further distance, the first traction member 3 of the first driven door panel 13 pulls the second traction member 4 of the second driven door panel 14, and the second driven door panel 14 joins the movement sequence. The entire opening process resembles a precise mechanical performance, both elegant and mysterious.

[0068] This embodiment combines artistry and functionality, serving as both a beautiful display piece and a practical storage solution. The elegant door movement sequence, coupled with intelligent sensing, creates a unique user experience. The design of this embodiment expands the traditional definition of a toy, enabling the product to appeal to a wider age range, including adult collectors.
