Description

Technical Field

[0001] This application relates to the field of toy technology, and more particularly to pitch structures and toys. Background Technology

[0002] A wide variety of toys are not only used for children's play, but are also widely used in commercial activities, theme parks, natural scenic areas and other places as decorations and interactive installations.

[0003] However, most toys currently on the market are presented in a fixed form, which results in a monotonous structure, insufficient fun, and an inability to meet people's needs.

[0004] Therefore, there is an urgent need for pitch structures and toys to address, to some extent, the technical problems existing in the current technology. Utility Model Content

[0005] The purpose of this application is to provide a pitch structure and a toy that, to a certain extent, solves the technical problem of low fun in existing toys.

[0006] This application provides a pitch structure, including a housing, a pitch assembly and a reset member rotatably disposed at one end of the housing via a rotating shaft, and a drive assembly, a transmission assembly and a limiting assembly disposed at the other end of the housing;

[0007] The winding end of the reset member is wound around the protruding post corresponding to the rotation axis, and its two ends are respectively connected to the end of the pitch assembly away from the rotation axis and the housing.

[0008] The drive assembly is connected to the transmission assembly, and the output end of the transmission assembly is connected to one end of the pitch assembly via a pull rope; when the drive assembly drives the output end of the transmission assembly to rotate in the first direction, the pull rope is tightened; when the pull rope is tightened, the reset member is compressed, causing the pitch assembly to rotate in the second direction and be in a latched state;

[0009] The limiting component is disposed on the transmission component. When the drive component rotates along the first direction, the limiting component can restrict the output end of the transmission component from rotating in the opposite direction to the first direction, so that the pitch component remains in the locked state.

[0010] When the drive assembly drives the transmission assembly to rotate in the opposite direction to the first direction, the transmission assembly releases the pull rope, the reset member resets, and the pitch assembly can be rotated open from the locked state in the opposite direction to the second direction, so that the pitch assembly is in the open state.

[0011] In the above technical solution, the transmission assembly further includes gears and a winch component;

[0012] The gears are provided in multiples, and adjacent gears are meshed and connected. The gear at the first end is connected to the drive assembly via a drive disk and a belt, so that the drive assembly can drive the gear connected to it to rotate via the belt.

[0013] The winch component is coaxial with the gear at the tail end; when the drive assembly rotates along the first direction, the gear can drive the winch component to rotate along the first direction so that the pull rope is wound around the winch component; when the drive assembly rotates in the opposite direction to the first direction, the limiting component can separate the gear at the tail end from the gear meshing with the tail end, the reset component resets, and the winch component rotates in the opposite direction to the first direction so that the pull rope is slack off from the winch component.

[0014] In the above technical solution, the gears are further provided in seven parts, namely the first gear, the second gear, the third gear, the fourth gear, the fifth gear, the sixth gear and the seventh gear;

[0015] The first gear serves as the head gear, and the seventh gear serves as the tail gear.

[0016] In the above technical solution, the limiting component further includes a first limiting torsion spring, a second limiting torsion spring, a limiting buckle, and a first limiting plate;

[0017] The toothed shafts of the fifth gear and the sixth gear respectively pass through the first limiting plate; the limiting buckle is located on the side of the sixth gear away from the seventh gear, and is set on the first limiting plate through the limiting shaft;

[0018] The limiting buckle has a limiting portion that extends toward the toothed disc of the sixth gear and engages with the toothed disc of the sixth gear; the limiting buckle is located on a side away from the sixth gear and a limiting groove is formed between it and the limiting portion;

[0019] The first limiting torsion spring is wound around the limiting shaft below the limiting buckle, and its two ends abut against the first limiting plate and the limiting groove respectively; when the driving assembly rotates along the first direction, it can drive the seventh gear to rotate along the first direction.

[0020] The second limiting torsion spring is wound around the gear shaft of the sixth gear below the first limiting plate, and its two ends are respectively fixed to the bottom wall of the gearbox and the first limiting plate; when the driving assembly rotates in the opposite direction to the first direction, the limiting buckle limits the gear disk of the sixth gear, so that the fifth gear and the sixth gear are an integral structure, the fifth gear can drive the sixth gear to move away from the seventh gear, and the second limiting torsion spring is compressed.

[0021] In the above technical solution, the limiting component further includes a second limiting plate;

[0022] The second limiting plate is disposed on the side of the gear away from the first limiting plate, and the gear shaft of the fifth gear, the gear shaft of the sixth gear, and the limiting shaft respectively pass through the second limiting plate.

[0023] In the above technical solution, the winch component further includes a square shaft and a winch.

[0024] The square shaft passes sequentially through the winch and the seventh gear, and the winch is used to wind the pull rope.

[0025] In the above technical solution, the pitch component further includes a rocker arm;

[0026] A support frame is provided on the housing, and the rocker arm is connected to the support frame through the rotating shaft;

[0027] The rocker arm has a connecting part on the side away from the support frame, one end of the pull rope is connected to the connecting part and the other end is connected to the winch;

[0028] The rocker arm has a hook-on part on its side wall and at the end opposite to the rotation axis. The two ends of the reset member are respectively connected to the hook-on part and the support frame.

[0029] In the above technical solution, the pitch structure further includes a limit switch; the limit switch is disposed at one end of the support frame away from the rotation axis;

[0030] A trigger part is provided on the side wall of the rocker arm facing the support frame. When the rocker arm is in the latching state, the trigger part can trigger the limit switch, so that the limit switch sends a latching signal.

[0031] In the above technical solution, the pitch structure further includes a controller and control buttons;

[0032] The controller is connected to the limit switch and can receive the engagement signal sent by the limit switch;

[0033] The control button is connected to the drive assembly. When the limit switch sends the engagement signal, pressing the control button can drive the transmission assembly to rotate in the opposite direction to the first direction, so that the pull rope is released from the winch and the rocker arm is in the open state.

[0034] This application also provides a toy including the aforementioned pitch structure.

[0035] Compared with the prior art, this application has the following beneficial effects:

[0036] This application discloses a pitch structure, including a housing, a pitch assembly and a reset member rotatably disposed at one end of the housing via a rotating shaft, and a drive assembly, a transmission assembly and a limiting assembly disposed at the other end of the housing;

[0037] The winding end of the reset member is wound around the protruding post corresponding to the rotation axis, and its two ends are respectively connected to the end of the pitch assembly away from the rotation axis and the housing.

[0038] The drive assembly is connected to the transmission assembly, and the output end of the transmission assembly is connected to one end of the pitch assembly via a pull rope; when the drive assembly drives the output end of the transmission assembly to rotate in the first direction, the pull rope is tightened; when the pull rope is tightened, the reset member is compressed, causing the pitch assembly to rotate in the second direction and be in a latched state;

[0039] The limiting component is disposed on the transmission component. When the drive component rotates along the first direction, the limiting component can restrict the output end of the transmission component from rotating in the opposite direction to the first direction, so that the pitch component remains in the locked state.

[0040] When the drive assembly drives the transmission assembly to rotate in the opposite direction to the first direction, the transmission assembly releases the pull rope, the reset member resets, and the pitch assembly can be rotated open from the locked state in the opposite direction to the second direction, so that the pitch assembly is in the open state.

[0041] In summary, this application achieves the locking and unlocking of the rocker arm by cleverly cooperating with the drive component, transmission component, and limiting component. When a toy shell is installed on the pitch component of the pitch structure, the head of the toy can be locked and unlocked, thereby increasing the toy's fun factor.

[0042] This application also provides a toy including the aforementioned pitch structure. The beneficial effects of having a pitch structure will not be specifically described here. Attached Figure Description

[0065] 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.

[0066] 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.

[0067] 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.

[0068] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] Example 1

[0075] This embodiment provides a pitch structure. By mounting a housing 1 to the outside of this pitch structure, a toy can be formed. This pitch structure can, to some extent, solve the technical problem of insufficient fun in existing toys. The following describes... Figures 1-20 This application provides a detailed description of a pitch structure.

[0076] Combination Figures 1-20 As shown, the pitch structure includes a housing 1, a pitch assembly 2 and a reset component 3 rotatably mounted at one end of the housing 1 via a rotating shaft, and a drive assembly 4, a transmission assembly 5, and a limiting assembly 6 mounted at the other end of the housing 1. The specific structure and connection relationship of the pitch assembly 2, the reset component 3, the drive assembly 4, the transmission assembly 5, and the limiting assembly 6 will be described in detail below.

[0077] Specifically, in combination Figure 1 , Figure 3 , Figure 5 as well as Figure 6 As shown, the housing 1 has a cylindrical structure, which encloses an installation space for mounting the drive assembly 4, the transmission assembly 5, and the limiting assembly 6. Further, combined with... Figure 6 As shown, a support frame 102 is provided on the top of the housing 1, and the support extends along the height direction of the housing 1. Specifically, there are two support frames 102, which are opposite each other and have a cavity in the middle that can accommodate the pitch component 2. One end of the pitch component 2 is rotatably connected to the support frame 102 through a rotating shaft.

[0078] Specifically, in combination Figures 1-6 As shown, the pitch assembly 2 includes a rocker arm 201; the rocker arm 201 is located within the receiving cavity and is connected to the support frame 102 via a rotating shaft. Two opposing sidewalls of the support frames 102, corresponding to the position of the rotating shaft, are provided with protruding posts 101. These protruding posts are used to fix the winding end 302 of the reset member 3 (reset torsion spring 301), i.e., the winding end 302 of the reset member 3 (reset torsion spring 301) is wound around the protruding post 101. The side of the rocker arm 201 facing away from the support frame 102 has a connecting portion 103; optionally, the connecting portion 103 is a connecting ring 104, one end of the pull rope 7 is connected to the connecting ring 104, and the other end is connected to the output end of the transmission assembly 5. Additionally, the rocker arm is provided with a hanging portion 202 for hanging the toy's outer shell.

[0079] Specifically, in combination Figures 1-6 As shown, a hook-on portion 105 is provided on the side wall of the rocker arm 201 at the end opposite to the rotation axis; optionally, the hook-on portion 105 is a hook-on shaft 106, and the two ends of the reset member 3 are respectively connected to the hook-on shaft 106 and the support frame 102. Further, the reset member 3 is a reset torsion spring 301; the winding end 302 of the reset torsion spring 301 is wound around the rotation axis, and the two fixed ends 303 of the reset torsion spring 301 are respectively fixed to the hook-on shaft 106 and the support frame 102. Figure 6 As shown, the reset torsion spring 301 is in the reset state at this time, and the rocker arm 201 is in the open state. Figure 1 and Figure 2 As shown, the reset torsion spring 301 is in a compressed state at this time, and the rocker arm 201 is in a locked state.

[0080] Specifically, in combination Figure 8 As shown, the drive component 4 is preferably a drive motor 401, which is connected to the transmission component 5. The output end of the transmission component 5 is connected to one end of the pitch component 2 via a pull rope 7.

[0081] In actual use, when the drive assembly 4 drives the output end of the transmission assembly 5 to rotate along the first direction 8, it can tighten the pull rope 7. When the pull rope 7 is tightened, the reset torsion spring 301 is compressed, causing the pitch assembly 2 to rotate toward the second direction 9 and be in a locked state. It should be noted that the limiting assembly 6 is set on the transmission assembly 5. When the drive assembly 4 rotates along the first direction 8, the limiting assembly 6 can restrict the output end of the transmission assembly 5 from rotating in the opposite direction to the first direction 8. That is, the limiting assembly 6 will not restrict the normal movement of the transmission assembly 5 rotating along the first direction 8, and the pitch assembly 2 can always remain in a locked state.

[0082] When the drive assembly 4 drives the transmission assembly 5 to rotate in the opposite direction to the first direction 8, the transmission assembly 5 releases the pull rope 7, the reset member 3 resets, and the pitch assembly 2 can be opened from the locked state in the opposite direction to the second direction 9, so that the pitch assembly 2 is in the open state.

[0083] In summary, this application achieves the locking and unlocking of the rocker arm 201 by cleverly cooperating with the drive component 4, the transmission component 5, and the limiting component 6. When a toy shell is installed on the pitch component 2 of the pitch structure, the head of the toy can be locked and unlocked, thereby improving the fun of the toy.

[0084] In this embodiment, the transmission assembly 5 includes gears and a winch component 502; the following is in conjunction with... Figures 7-20 As shown, the specific structure and connection relationship of the gear and winch component 502 are described in detail.

[0085] Specifically, multiple gears are provided. Preferably, seven gears are provided, namely a first gear 505, a second gear 506, a third gear 507, a fourth gear 508, a fifth gear 509, a sixth gear 510, and a seventh gear 511. Each gear has a gear shaft 501 and a gear disc 512 sleeved on the gear shaft 501. In addition, the first gear 505 is the leading gear, and the seventh gear 511 is the trailing gear, i.e., the output gear of the transmission assembly 5. Furthermore, the above-mentioned adjacent gears are meshed together, and the leading gear 505 is connected to the drive motor 401 via a drive disc 503 and a belt 504, so that the drive assembly 4 can drive the first gear 505 to rotate via the belt 504.

[0086] Preferably, the first gear 505, the second gear 506, the third gear 507, the fourth gear 508, the fifth gear 509, the sixth gear 510, and the seventh gear 511 are arranged in a triangular pattern. The first gear 505, the second gear 506, the third gear 507, and the fourth gear 508 form the first side of the triangular pattern, the fourth gear 508, the fifth gear 509, and the sixth gear 510 form the second side of the triangular pattern, and the sixth gear 510 and the seventh gear 511 form the third side of the triangular pattern.

[0087] Specifically, the winch assembly 502 and the seventh gear 511 are provided with shafts. Further, the winch assembly 502 includes a square shaft 514 and a winch 515; the square shaft 514 passes through the winch 515 and the seventh gear 511 in sequence, and the winch 515 is used to wind the pull rope 7.

[0088] In actual use, when the drive assembly 4 rotates along the first direction 8, it sequentially drives the winch assembly 502 to rotate along the first direction 8 via the second gear 506, the third gear 507, the fourth gear 508, the fifth gear 509, the sixth gear 510, and the seventh gear 511, so that the pull rope 7 is wound around the winch assembly 502, which is equivalent to tightening (contracting) the pull rope 7; when the drive assembly 4 rotates in the opposite direction to the first direction 8, the limiting assembly 6 can disconnect the originally meshed seventh gear 511 and... The sixth gear 510 disengages, disengaging the seventh gear 511 from the sixth gear 510. This means there is no connection between the seventh gear 511 and the sixth gear 510, placing the seventh gear 511 free and relieving it of any pressure on the return torsion spring 301. The return torsion spring 301 then resets, pulling the pull rope 7 and causing the winch assembly 502 to rotate in the opposite direction to the first direction 8. Ultimately, the pull rope 7 is released from the winch assembly 502. This process effectively opens the pitch assembly 2 from the engaged state by rotating it in the opposite direction to the second direction 9, placing the pitch assembly 2 in the open state.

[0089] Specifically, in combination Figures 7-20As shown, the limiting assembly 6 includes a first limiting torsion spring 601, a second limiting torsion spring 608, a limiting buckle 602, and a first limiting plate 603. The first limiting plate 603 is triangular, with the gear shafts 501 of the fifth gear 509 and the sixth gear 510 passing through the first and second corner ends of the first limiting plate 603, respectively. The gear discs 512 of both the fifth gear 509 and the sixth gear 510 are located above the first limiting plate 603. The limiting buckle 602 is located on the side of the sixth gear 510 facing away from the seventh gear 511 and is disposed at the triangular end of the first limiting plate 603 via a limiting shaft 604. Further, the limiting buckle 602 has a limiting portion 605 extending toward and engaging with the gear disc 512 of the sixth gear 510. Preferably, the limiting portion 605 is a limiting protrusion. In addition, the limiting buckle 602 is located on the side opposite to the sixth gear 510 and is surrounded by a limiting groove 606 between itself and the limiting part 605.

[0090] Specifically, the first limiting torsion spring 601 is wound around the limiting shaft 604 below the limiting buckle 602, and its two ends abut against the first limiting plate 603 and the limiting groove 606, respectively. Further, one end of the first limiting torsion spring 601 abuts against the limiting groove 606, and the other end is fixed to the side of the gear shaft 501 of the sixth gear 510 near the gear shaft 501 of the fifth gear 509. The limiting protrusion can restrict the movement of the sixth gear 510 in the direction opposite to the first direction 8, without preventing the sixth gear 510 from rotating in the first direction 8. Therefore, when the drive assembly 4 rotates in the first direction 8, it can drive the seventh gear 511 to rotate in the first direction 8.

[0091] Specifically, the second limiting torsion spring 608 is wound around the gear shaft 501 of the sixth gear 510 below the first limiting plate 603, and its two ends are respectively fixed to the bottom wall of the gearbox 513 and the first limiting plate 603. Specifically, one end of the second limiting torsion spring 608 abuts against the gearbox 513 and the side away from the sixth gear 510, and the other end abuts against the middle position between the gear shaft 501 of the sixth gear 510 and the limiting shaft 604 on the first limiting plate 603.

[0092] In actual use, when the drive assembly 4 rotates in the opposite direction to the first direction 8, the limiting buckle 602 limits the gear disk 512 of the sixth gear 510, making the fifth gear 509 and the sixth gear 510 an integral structure. When the fourth gear 508 drives the gear disk 512 of the fifth gear 509 to rotate, the first limiting plate 603 of the fifth gear 509 and the limiting buckle 602 of the sixth gear 510 can all rotate around the gear shaft 501 of the fifth gear 509 in the opposite direction to the first direction 8, thereby causing the sixth gear 510 to move away from the seventh gear 511, that is, to separate the sixth gear 510 from the seventh gear 511, thereby realizing the movement of the rocker arm 201 in the opposite direction to the second direction 9. It is worth noting that: during the rotation of the fifth gear 509, the sixth gear 510, the first limiting plate 603, and the limiting buckle 602 around the gear shaft 501 of the fifth gear 509 in the opposite direction to the first direction 8, the second limiting torsion spring 608 is compressed; when the drive assembly 4 drives the transmission assembly 5 in the first direction 8, the second limiting torsion spring 608 will reset.

[0093] The limiting assembly 6 also includes a second limiting plate 607; the second limiting plate 607 is disposed on the side of the gear away from the first limiting plate 603, and the gear shaft 501 of the seventh gear 511, the gear shaft 501 of the sixth gear 510, and the limiting shaft 604 respectively pass through the second limiting plate 607. The second limiting plate 607 is used to fix the gear shaft 501 of the fifth gear 509 and the gear shaft 501 of the sixth gear 510.

[0094] It is worth noting that the aforementioned transmission components and limiting components are located inside the gearbox.

[0095] In this embodiment, the pitch structure further includes a limit switch 10; the limit switch 10 is disposed at the end of the support frame 102 away from the rotation axis; a trigger part 203 is disposed on the side wall of the rocker arm 201 facing the support frame 102; optionally, the trigger part 203 is a trigger protrusion 204 formed on the rocker arm 201. When the rocker arm 201 is in the latching state, the trigger part 203 can trigger the limit switch 10, causing the limit switch 10 to issue a latching signal.

[0096] Furthermore, the pitch structure also includes a controller and a control button; the controller is connected to the limit switch 10 and can receive the engagement signal issued by the limit switch 10; when the limit switch issues an engagement signal; the control button is connected to the drive assembly 4, and when the display shows the engagement signal, pressing the control button can drive the transmission assembly 5 to rotate in the opposite direction to the first direction 8 using the drive assembly 4, so that the pull rope 7 is released to the winch 515 and the rocker arm 201 is in the open state.

[0097] It is worth noting that the controller, limit switch 10 and control button are electrically connected, and there is no calculation between the signals. They simply perform the functions that the controller itself can achieve, and there is no improvement to its control part.
