For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0058] Embodiment one: as Figures 1 to 10As shown, the embodiment of the present application provides a mechanical toy unit, which comprises a shell 1, a rotating part 2, an elastic part 3 and a clamping part 4. The shell 1 has a cavity, and opposite sides of the shell 1 are respectively provided with a plug barrel part 11 and a plug hole 12, both of which are communicated with the cavity, and the shell 1 is provided with a window 13 communicated with the cavity. The rotating part 2 is rotatably arranged in the shell 1, and the rotating part 2 has an outer door body 21 and an inner door body 22. The elastic part 3 abuts against the shell 1 and the rotating part 2 respectively. The clamping part 4 is movably arranged in the cavity, and the clamping part 4 has a linkage shaft 41. The mechanical toy unit has a first state and a second state. In the first state, the outer door body 21 closes the window 13, the inner door body 22 is located in the cavity and is clamped to the clamping part 4, and the linkage shaft 41 is located inside the cavity or the plug barrel. In the second state, the clamping part 4 releases the outer door body 21, the elastic part 3 pushes the rotating part 2 to rotate to the outer door body 21 moving out of the window 13, the inner door body 22 closes the window 13, and the linkage shaft 41 extends out of the plug barrel part 11. A plurality of mechanical toy units can be arranged in sequence. In adjacent two of them, the plug barrel part 11 on one can be inserted into the plug hole 12 of the other, and when the linkage shaft 41 of one extends out of the plug barrel part 11, it can push the clamping part 4 of the other to release the corresponding rotating part.
[0059] The mechanical toy unit provided by the present application can realize linkage of at least one other mechanical toy unit on one mechanical toy unit, and make the other mechanical toy units inserted behind the first mechanical unit sequentially release the rotating part.
[0060] When the mechanical toy units are combined into an assembly, the adjacent plug barrel part 11 and plug hole 12 of the units are inserted in sequence, and the insertion depth is accurately designed to ensure that the linkage shaft 41 can accurately push the clamping part 4 of the other unit. In actual play, children only need to trigger the linkage shaft 41 of the first unit to make the subsequent multiple units release the rotating part in sequence through the chain reaction, realize complex and interesting dynamic effects, and greatly improve the interestingness and explorability of the toy.
[0061] This mechanical toy features a modular design, with each unit possessing independent function and structure. Furthermore, multiple units can be arranged and combined sequentially through the cooperation of the insert section 11 and the insertion hole 12. This design not only facilitates the toy's portability and storage but also makes its gameplay more diverse and flexible. Users can combine multiple units into toy components of various shapes and structures based on their creativity and imagination, thus experiencing different kinds of play.
[0062] In the structural design of the individual mechanical toy units, the cooperation of the rotating component 2, the elastic component 3, and the locking component 4 plays a crucial role. The rotation of the rotating component 2 and the pushing action of the elastic component 3 enable the switching between the outer door 21 and the inner door 22, thereby triggering different functions of the individual mechanical toy units. Simultaneously, the movable design of the locking component 4 makes linkage between units possible. When the linkage shaft 41 of one unit extends out of the insert 11, it can push the locking component 4 of the other unit to release the corresponding rotating component, thus achieving dynamic changes in the entire toy assembly.
[0063] Furthermore, this application also emphasizes the detailed design of the individual mechanical toy units. For example, the areas of both the outer door 21 and the inner door 22 are no larger than the window 13, ensuring that the doors can smoothly fit into or extend from the window 13. The baffle 222 and decorative parts connected to the inner door 22 not only enhance the toy's aesthetics but also improve its interactivity and fun. Meanwhile, the design of the pressing part 5 and the elastic reset part 6 allows users to easily switch the state (open the door) and trigger linkages of the individual mechanical toy units with a simple one-button press, further reducing the difficulty of using the toy and increasing its playability.
[0064] In one possible implementation, the rotating component 2 is provided with a rotating shaft 23, the inner door body 22 is provided with a hook portion 221, and the elastic component includes a spiral segment 31 and torsion arms 32 disposed at both ends of the spiral segment 31. The spiral segment 31 is sleeved on the rotating shaft 23, one of the two torsion arms 32 abuts against the outer shell 1, and the other is confined to the hook portion 221. When the outer door body 21 closes the window 13, the hook portion 221 abuts against the torsion arm 32 and elastically deforms, opening outward. When the locking component 4 releases the outer door body 21, the torsion arm 32 pushes against the hook portion 221, causing the rotating component 2 to rotate, so that the outer door body 21 moves out of the window 13, and the inner door 22 closes the window 13.
[0065] In a feasible embodiment, the outer door body 21 and the inner door body 22 are further optimized in design, and the areas thereof are accurately matched with the size of the window 13, so as to ensure close closing to prevent components from falling off accidentally and smooth action during state switching. The blocking rib 222 on the inner door body 22 is rounded to avoid scratching the inner wall of the shell 1 to generate abnormal sound, and the length thereof is calculated to ensure that the inner door body 22 can be accurately stopped at a specific position of the inner wall of the shell 1 in the second state, thereby providing stable support for the inner door body 22.
[0066] In a feasible embodiment, the area of the outer door body 21 and the area of the inner door body 22 are not greater than the area of the window 13, the outer door body 21 can be embedded in or protrude out of the window 13, and the inner door body 22 is connected with a blocking rib 222. In the second state, the inner door body 22 is embedded in the window 13, and the blocking rib 222 is stopped at the inner wall of the shell 1. The outer door body 21 is just embedded in the window 13, the inner door body 22 is stopped at the inner wall of the shell 1, and the inner door body 22 is clamped to the clamping piece 4. Such a design can stably maintain the first state and the second state of the single machine gun toy, and the state will not be changed due to slight shaking or external force, thereby effectively ensuring the stability and reliability of the toy during playing.
[0067] In a feasible embodiment, a modeling piece is installed on the side of the inner door body 22 close to the outer door body 21. The modeling piece can be customized according to different themes or scenes, such as cartoon characters, animal shapes, etc., thereby adding rich visual elements and interest to the single machine gun toy. When the single machine gun toy is in the first state, the modeling piece is hidden inside the window 13 and is not easy to be noticed. In the second state, the modeling piece is exposed with the rotation of the inner door body 22, thereby bringing unexpected surprises to the user. Meanwhile, the modeling piece is simple and convenient to install, and can be fixed on the inner door body 22 through various ways such as insertion and adhesion, thereby facilitating the user to replace and adjust according to personal preferences.
[0068] In a feasible embodiment, a convex shaft 24 or a groove is arranged on the side of the inner door body 22 close to the outer door body 21, and the modeling piece has a groove or a convex shaft 24. In the state that the modeling piece is connected to the inner door body 22, the convex shaft 24 and the groove are inserted and matched. Such an insertion and matching manner is not only stable in connection, but also can effectively prevent the modeling piece from falling off or shifting during the state switching of the single machine gun toy, and is very convenient to install and disassemble. The user only needs to align the groove or the convex shaft 24 on the modeling piece with the convex shaft 24 or the groove on the inner door body 22, and press or pull gently, so as to complete the installation or replacement of the modeling piece.
[0069] In a feasible embodiment, a flange 25 is arranged at the lower edge of the inner door body 22, and the modeling part is supported on the flange 25. The flange 25 plays a dual role. On the one hand, it provides a stable support platform for the modeling part, so that the modeling part can be more firmly installed on the inner door body 22 and will not easily fall off due to shaking or rotation of the single unit of the mechanical toy. On the other hand, the flange 25 can also limit the installation position of the modeling part to some extent, ensuring the neatness and aesthetics of the installation of the modeling part. At the same time, the shape and size of the flange 25 can be designed according to actual needs, which can meet the function of supporting the modeling part and will not affect the overall appearance of the single unit of the mechanical toy.
[0070] In a feasible embodiment, the single unit of the mechanical toy comprises a pressing part 5 and an elastic reset part 6, the clamping part 4 is slidably arranged in the shell 1, and the clamping part 4 is provided with a slanted groove 42 and a clamping jaw 43. The pressing part 5 is telescopically arranged in the shell 1, the elastic reset part 6 is arranged between the pressing part 5 and the shell 1, the pressing part 5 has a push shaft 51 which is inserted into the slanted groove 42. When the user presses the pressing part 5, the push shaft 51 will slide in the slanted groove 42, thereby pushing the clamping part 4 to slide in a specific direction. In the first state, the clamping jaw 43 clamps the inner door body 22, so that the inner door body 22 remains in a fixed position. When the pressing part 5 moves inward under the action of external force, the push shaft 51 pushes the clamping part 4 to slide, and the clamping jaw 43 gradually releases the rotating part 2. At this time, the elastic force of the elastic part 3 will cause the rotating part 2 to rotate, thereby realizing the change of the state of the single unit of the mechanical toy. When the external force is removed, the elastic reset part 6 restores the deformation, and pushes the pressing part 5 and the clamping part 4 to reset, preparing for the next operation. This design makes the operation of the single unit of the mechanical toy more convenient and intuitive, and children can easily trigger various functions of the single unit of the mechanical toy through pressing action.
[0071] In a feasible embodiment, a first cylinder wall 14 is arranged on the inner wall of the shell 1, the first cylinder wall 14 communicates with the insertion hole 12, a first matching plate 44 is arranged on the clamping part 4, and the first matching plate 44 is slidably arranged in the first cylinder wall 14. The cooperation of the first cylinder wall 14 and the first matching plate 44 provides accurate guidance for the movement of the clamping part 4, ensuring that the clamping part 4 can maintain a stable movement track during sliding and will not deviate or jam. At the same time, this design can also effectively limit the movement range of the clamping part 4, preventing the clamping part 4 from sliding excessively and affecting the normal function of the single unit of the mechanical toy. When adjacent single units of the mechanical toy are inserted, the linkage shaft 41 of one extends out of the insertion cylinder part 11 and enters the insertion hole 12 of the other, and at the same time interacts with the first matching plate 44 on the clamping part 4 to push the clamping part 4 to slide, thereby realizing the linkage between the single units of the mechanical toy.
[0072] Furthermore, a horizontal plate 46 is provided on the first mating plate 44, and a groove is provided on the first cylinder wall 14. The horizontal plate 46 is slidably embedded in the groove. The cooperation between the horizontal plate 46 and the groove further enhances the stability of the movement of the snap-fit component 4 and also provides a certain supporting effect. During the sliding process of the snap-fit component 4, the horizontal plate 46 moves synchronously within the groove, which not only limits the displacement of the snap-fit component 4 in the direction perpendicular to the sliding direction, preventing it from shaking or tilting, but also precisely controls the sliding stroke of the snap-fit component 4 by the length of the groove.
[0073] In one feasible embodiment, a second cylindrical wall 15 is provided on the inner wall of the outer shell 1, the second cylindrical wall 15 communicating with the insert portion 11. A second mating plate 45 is provided on the snap-fit member 4, and the linkage shaft 41 is disposed on the second mating plate 45. The second mating plate 45 is slidably disposed within the second cylindrical wall 15. The cooperation between the second cylindrical wall 15 and the second mating plate 45 further enhances the stability and accuracy of the movement of the linkage shaft 41. The linkage shaft 41 slides within the second cylindrical wall 15 through the second mating plate 45, enabling precise transmission of power to the snap-fit members 4 of adjacent mechanical toy units, ensuring a more reliable and smooth linkage effect between multiple mechanical toy units. This sophisticated structural design reflects the technological innovation and advancement of the mechanical toy units in this application, bringing children a richer and more interesting play experience.
[0074] Example 2: Figures 1 to 10 As shown, this application provides a mechanical toy assembly, including multiple mechanical toy units as described in Embodiment 1. These mechanical toy units are arranged sequentially, with the insert portion 11 of one unit able to be inserted into the insertion hole 12 of the other. When the linkage shaft 41 of one unit extends out of the insert portion 11, it can push the locking member 4 of the other unit to release the corresponding rotating component. This embodiment provides a mechanical toy assembly including multiple mechanical toy units arranged sequentially. The insertion depth of the insert portion 11 and insertion hole 12 of adjacent units is precisely designed to ensure that the linkage shaft 41 can accurately push the locking member 4 of the other unit. In actual play, children only need to trigger the linkage shaft 41 of the first unit to trigger a chain reaction, causing multiple subsequent units to release their rotating components sequentially, achieving complex and interesting dynamic effects, greatly enhancing the toy's fun and exploratory nature.
