Detailed Implementation

[0053] The following detailed embodiments are provided to aid the reader in gaining a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0054] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0055] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0056] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0057] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0058] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., swung 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0059] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0060] Variations in the shapes shown in the accompanying drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include changes in shape that may occur during manufacturing.

[0061] The features of the examples described herein can be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0062] Example 1

[0063] This application provides an opening and closing structure that can open or close. When applied to amusement facilities, this structure allows toys within the facility to assume different postures, thus increasing the fun to some extent. The following is a combination of... Figures 1-14 Describe the specific structure of this opening and closing mechanism in detail.

[0064] Combination Figure 3 As shown, the opening and closing structure includes a housing 1. Specifically, the housing 1 includes a first housing body 101, a second housing body 102, a first extension plate 103, and a second extension plate 104; wherein the first housing body 101 and the second housing body 102 are interlocked together and enclose an installation cavity. Figure 3Taking the direction shown in the figure as an example, the first shell body 101 extends upward with a first extension plate 103, the second shell body 102 extends upward with a second extension plate 104, and an installation space is formed between the first extension plate 103 and the second extension plate 104.

[0065] Combination Figure 1 and Figure 2 As shown, the opening and closing structure also includes a four-bar linkage 3. Specifically, the four-bar linkage 3 has a rod portion 301 and an extension portion 302 extending from the rod portion 301. Specifically, the rod portion 301 includes a first link 303, a second link 304, a third link 305, and a fourth link 306 that are rotatably connected in sequence. The extension portion 302 includes a first extension rod 307, a second extension rod 308, and a third extension rod 309. The first extension rod 307 extends from the first link 303 along its axial direction, the second extension rod 308 extends from the second link 304 along its axial direction, and the third extension rod 309 extends from the third link 305 along its axial direction.

[0066] Furthermore, combined Figure 3 As shown, the end of the first extension rod 307 facing away from the first connecting rod 303 extends into the mounting space and is rotatably connected to the first extension plate 103 and the second extension plate 104 via a rotating shaft. Furthermore, the rotating shaft passes through the first extension plate 103, the first extension rod 307, and the second extension plate 104 in sequence, thus enabling the first extension rod 307 to be rotatably mounted on the first extension plate 103 and the second extension plate 104 around the rotating shaft.

[0067] Combination Figures 1-3 As shown, the opening and closing structure also includes a drive assembly 2, which is disposed within the mounting cavity. One end of the second extension rod 308, away from the second connecting rod 304, is rotatably connected to the drive assembly 2. The drive assembly 2 can drive the second extension rod 308 to move toward the first extension rod 307, which is rotatably connected to the first extension plate 103 and the second extension plate 104, so that the four-bar linkage 3 is in an open state; or the drive assembly 2 can drive the second extension rod 308 to move away from the first extension rod 307, which is rotatably connected to the housing 1, so that the four-bar linkage 3 is in a closed state.

[0068] Assume the initial state is Figure 4 The state shown is as follows: the end of the first extension rod 307 rotatably connected to the first extension plate 103 and the end of the second extension rod 308 rotatably connected to the drive assembly 2 are opposite to each other. At this time, the first extension rod 307 and the second extension plate 104 form an obtuse angle. In addition, the second connecting rod 304 and the fourth connecting rod 306 approach each other parallel to each other and finally approach the housing 1, and the third connecting rod 305 extends in a direction that forms an obtuse angle with the plane.

[0069] In actual use: the drive assembly 2 can drive the second extension rod 308 to slowly move towards the first extension rod 307, which is rotatably connected to the first extension plate 103 and the second extension plate 104; in other words, combined with Figure 9 As shown, the drive assembly 2 can drive the second link 304 to move upward. During the upward movement of the second extension rod 308, the first link 303, the first extension rod 307, the third link 305, and the fourth link 306 will rotate relative to each other. Ultimately, the second link 304 and the fourth link 306 will extend in a direction away from the housing 1, and the third link 305 will extend at an acute angle to the plane. In summary, combined with Figure 3 As shown, the four-bar linkage will eventually be in an open state.

[0070] The drive assembly 2 can also drive the second link 304 to move downwards. During the downward movement of the second extension rod 308, the first link 303, the first extension rod 307, the third link 305, and the fourth link 306 will rotate relative to each other, ultimately causing the first extension rod 307 to form an obtuse angle with the second extension plate 104 again. Furthermore, the second link 304 and the fourth link 306 will again move parallel to each other and eventually converge towards the housing 1, while the third link 305 extends in a direction forming an obtuse angle with the plane. In summary, combined with... Figure 4 As shown, the four-bar linkage will eventually reach a closed state.

[0071] In summary, this application utilizes the drive component 2 to drive the four-bar linkage 3 to a closed or open state. When applied to amusement facilities, it enables the toys inside the amusement facilities to assume different postures, thus increasing the fun to a certain extent.

[0072] In this embodiment, combined with Figure 6 As shown, the third extension rod 309 is connected to the rocker arm 310. When the fourth link 306 rotates, the rocker arm 310 will also rotate in coordination with the fourth link 306. That is to say, the rocker arm 310 can be in a closed state or an open state. In practical applications, other decorative shells 1 can be installed on the rocker arm 310 to further increase the fun of the toy.

[0073] In this embodiment, the drive assembly 2 includes a drive unit 203 and a transmission unit; the drive unit 203 is connected to the transmission unit, and the transmission unit is rotatably connected to the extension unit 302; when the drive unit 203 drives the transmission unit to move along the second direction 209, the four-bar linkage 3 can be in an open state or a closed state. The structure of the drive unit 203 and the transmission unit and the connection relationship between them are described in detail below.

[0074] Combination Figure 7 and Figure 8As shown, the drive unit 203 is a drive motor 201, and the transmission unit includes a transmission gearbox 202 and a drive gear. Specifically, the housing extends along the first direction 205, combined with... Figure 9 As shown, the first direction 205 preferably refers to the width direction of the housing 1. The housing extends along the first direction 205, that is, the housing extends along the width direction of the housing 1, and... Figures 7-12 As can be seen, both ends of the housing along the first direction 205 extend and protrude beyond the width direction of the shell 1. Furthermore, at least one end of the housing along the first direction 205 is rotatably connected to a second extension rod 308; that is, when there is one set of four-bar linkage 3, it can be rotatably connected to one end of the housing extending along the first direction 205. When there are two sets of four-bar linkage 3, the two sets of four-bar linkage 3 can be rotatably connected to both ends of the housing along the first direction 205, meaning that ultimately, there are four-bar linkage assemblies 3 on both sides of the width direction of the shell 1.

[0075] Specifically, the transmission gearbox 202 includes a housing and multiple gears disposed within the housing. These multiple gears are a first gear 206, a second gear 211, a third gear 212, a fourth gear 213, a fifth gear 214, a sixth gear 215, a seventh gear 216, and an eighth gear 217. (Combined with...) Figure 10 As shown, the first gear 206 and the fifth gear 214 are disposed inside the housing and located at the lower center of the housing; in addition, the small gear of the first gear 206 meshes with the small gear of the fifth gear 214, and the side of the first gear 206 away from the fifth gear 214 is also meshed with the second gear 211; the side of the second gear 211 away from the first gear 206 is also meshed with the third gear 212; the side of the third gear 212 away from the second gear 211 is also meshed with the fourth gear 213; the side of the fifth gear 214 away from the first gear 206 is also meshed with the sixth gear 215; the side of the sixth gear 215 away from the fifth gear 214 is also meshed with the seventh gear 216; the side of the seventh gear 216 away from the sixth gear 215 is also meshed with the eighth gear 217.

[0076] Furthermore, combined Figure 11 and Figure 12As shown, the first gear 206 also includes a gear shaft 207 and a wheel 220. The gear shaft 207 extends out of the housing, and the wheel 220 is fitted onto the gear shaft 207 extending out of the housing. The output shaft of the drive motor 201 is connected to the wheel 220 via a belt 208. When the drive motor 201 starts, the belt 208 drives the wheel 220 to rotate. Since the wheel 220 and the gear shaft 207 are fixed together, the gear shaft 207 will rotate as well. When the gear shaft 207 rotates, it will drive the first gear 206 to rotate. Since the first gear 206 is meshed with the fifth gear 214, it will drive the fifth gear 214 to rotate. In addition, since the first gear 206, the second gear 211, the third gear 212, and the fourth gear 213 mesh sequentially, when the first gear 206 rotates, the second gear 211, the third gear 212, and the fourth gear 213 will also rotate in coordination. Similarly, the sixth gear 215, the seventh gear 216, and the eighth gear 217 will also rotate in coordination.

[0077] Specifically, there are two drive gears: a first drive gear 204 and a second drive gear 218. The first drive gear 204 is coaxial with the eighth gear 217, and the second drive gear 218 is coaxial with the fourth gear 213. Furthermore, the gear shafts 207 of the eighth gear 217 and the fourth gear 213 extend out of the housing. The first drive gear 204 is fitted onto the eighth gear 217 extending out of the housing, and the second drive gear 218 is fitted onto the fourth gear 213 extending out of the housing.

[0078] Preferably, the first drive gear 204, the second drive gear 218, and the wheel 220 are disposed on the same side of the housing. More preferably, the first drive gear 204, the second drive gear 218, and the wheel 220 face the first housing body 101.

[0079] Specifically, the inner sidewall of the first housing body 101 is provided with a rack extending along the second direction 209; furthermore, there are two racks, namely a first rack 210 and a second rack 219; the first rack 210 and the second rack 219 are arranged at intervals along the first direction 205. In addition, the first rack 210 meshes with the second drive gear 218, and the second rack 219 meshes with the first drive gear 204.

[0080] In actual operation: First, the drive motor 201 is started, causing all gears in the transmission gearbox 202 to rotate. Then, the first drive gear 204 and the second drive gear 218, driven by the first gear 206 and the eighth gear 217, move along the second direction 209 on the first rack 210 and the second rack 219. Finally, when the first drive gear 204 and the second drive gear 218 move along the second direction 209 on the first rack 210 and the second rack 219, they can drive the transmission gearbox 202 and the drive motor 201 to move simultaneously along the second direction 209. When the transmission gearbox 202 moves in the second direction 209, the connecting rods in the four-bar linkage 3 rotate relative to each other, eventually reaching a closed or open state.

[0081] The above describes a structure with two racks, arranged at intervals along the first direction 205 on the first housing body 101. This two-rack structure effectively increases the connection point between the transmission gearbox 202 and the housing 1, thus making the transmission gearbox 202 more stable during movement along the second direction 209. However, it is worth noting that the number of racks is not limited to two; it can also be one. Furthermore, when there is one rack, there is also one drive gear. The driving process is as described above and will not be elaborated upon here.

[0082] Example 2

[0083] In this embodiment, another feasible solution is provided for the structure of the drive unit 203 and the transmission unit. Specifically, the drive unit 203 is a drive motor 201, and the transmission unit includes a lead screw and a slider; the lead screw extends along a second direction 209, the slider is sleeved on the lead screw and extends along a first direction 205, and its two ends along the first direction 205 are respectively rotatably connected to second extension rods 308. The output shaft of the drive motor 201 is connected to the lead screw and can drive the lead screw to rotate; when the lead screw rotates, the slider can move along the second direction 209 on the lead screw; when the slider moves along the second direction 209 on the lead screw, the four-bar linkage 3 can be in a closed state or an open state.

[0084] Furthermore, there are two drive motors 201, two lead screws, and one slider. The lead screws are spaced apart along the first direction 205 in the housing 1, and the two drive motors 201 drive the lead screws respectively. The slider extends along the first direction 205 and is sleeved on the two lead screws. This structure of two lead screws and two drive motors 201 provides a more stable driving force for the movement of the slider, thereby improving the accuracy of controlling the four-bar linkage 3.

[0085] Combination Figure 4 and Figure 5As shown, the opening and closing structure also includes a power supply unit, which is connected to the drive motor 201 and can supply power to the drive motor 201.

[0086] Specifically, the power supply unit includes a battery box 4 and a battery; the battery box 4 is disposed on the housing 1, and the battery is placed inside the battery box 4 to supply power to the drive motor 201.

[0087] Example 3

[0088] This application also provides a toy including the aforementioned opening and closing structure. In actual use, decorative fabric or the like, shaped like wings, is attached to the remote control of the opening and closing structure, making the toy more interesting or artistic in some festivals or performances, as it functions as an opening and closing wing structure.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
