Description

Technical Field

[0001] The utility model belongs to the field of toy products, in particular to a functional device with rolling and dispensing actions in electronic toy products. Background Art

[0002] Toy gear boxes are the main transmission components of electronic toy products with mechanical motion functions. Through the combination of multiple gears to form a connected power transmission, the power of the motor can be converted into rotational motion with different speeds, and can also be converted into various linear motions, reciprocating motions, and even curved motions, etc., and are widely used in children's toy products. Most gear boxes currently used in toy products are a closed structure that only provides a motor interface and a gear connection interface. The action function is relatively simple and only serves as a power transmission mechanism. These gear box products cannot meet the needs of specific toy products with multiple action effects. For example, how to have an electronic toy with a winding and storage action, and automatically dispatch thin sheet-like targets from the toy product as needed, is something that current gear box products cannot achieve. Utility Model Content

[0003] The purpose of the utility model is to provide a toy gear box with automatic winding and dispensing functions, which is provided with a swing wheel to cooperate with an inlet and an outlet structure, and an action structure combined with two groups of rollers and two groups of gear groups to realize the transmission functions of the two effects of winding and output, thereby overcoming the shortcomings of the complex structure of existing products.

[0004] To achieve the above-mentioned purpose, the technical scheme of the present invention is a toy gear box with automatic winding and dispensing functions, comprising a housing, a DC motor and a gear set. The housing is composed of a box plate and a cover plate, the upper ends of both of which form a strip-shaped inlet, and the lower ends form an outlet downward, and a transmission gear is installed at the outlet. The upper and lower parts of the strip-shaped inlet are installed with a first roller and a second roller to form a master-slave connection, and the first roller is a driving wheel. A disc gear or a worm is installed on the side end of the first roller. A DC motor is installed in the middle of the box plate, connected to a swing gear set, which is composed of a fixed wheel and a swing wheel. The upper part of the fixed wheel is connected to the DC motor transmission shaft, and the lower part is connected to the swing wheel. The fixed wheel is connected to the wheel shaft of the swing wheel through a swing rod. The wheel shaft of the swing wheel is inserted in the elliptical swing cavity formed by the box plate. The winding gear set is installed on the upper side of the swing wheel, and the winding gear set is meshed and connected with the disc wheel of the first roller. The dispensing gear set is installed on the lower side of the swing wheel, and the dispensing gear set is meshed and connected with the transmission gear.

[0005] The swing wheel of the utility model forms a rotating fan-shaped motion state with the fixed wheel under the limiting action of the swing rod. When the fixed wheel runs in the forward direction, the swing wheel is pulled and meshed in the direction of the upper winding gear set, and the rotation of the fixed wheel is transmitted to the winding gear set, and then the first roller and the second roller are driven to move through the operation of the disc gear or the worm. Thus, the thin sheet target object inserted and clamped by the first roller and the second roller is rolled into the interior of the toy product. When the fixed wheel runs in the reverse direction, the swing wheel is pulled and connected in the direction of the lower distribution gear set, and the rotation of the fixed wheel is transmitted to the distribution gear set, and the transmission gear is driven to move, and then other transmission machinery outside the gear box is linked to achieve the function of distributing the thin sheet target object inside the toy product to the outside. The setting of this swing gear set structure solves the effect of automatically transmitting the forward and reverse operation of the DC motor to different gear sets, and simplifies the structure of the gear box, reducing the production and assembly costs of the toy product.

[0006] Preferably, in the toy gear box with automatic winding and dispensing functions of the above structure, the fixed wheel is fixedly inserted. The box piece forms a rightward arc groove, and the axle of the swing wheel is inserted in the groove. The position of the groove makes the lower part of the fixed wheel mesh with the swing wheel, and the swing wheel meshes with the winding gear set when it moves to the upper end of the groove, and meshes with the dispensing gear set when it moves to the lower end of the groove.

[0007] The fixed wheel and the swing wheel are arranged to be inserted separately, and the lower part of the fixed wheel is meshed and connected with the swing wheel, which reduces the structure of the swing rod, simplifies the installation process, and reduces the production and assembly costs of the product. At the same time, since the fit between the arc groove and the swing wheel installation shaft will be tighter, there is only a small amount of movement, and the movement of the swing wheel in the arc groove will be smoother without jamming, which is a feature and advantage that other installation grooves and slot structures do not have.

[0008] The toy gear box of the utility model is provided with a roller group, two functional gear groups and a swing gear group with a power direction adjustment function on the basis of a structure with a DC motor as the power source. This combined structure realizes the function of rolling up and dispensing the sheet-like toy target and has the characteristic of a more compact structure. At the same time, its advantage is that after being combined with other structures of the toy product, it is smoother in realizing automatic action and overcomes the disadvantage that other structures are easy to get stuck.

[0011] Figure 3 It is a schematic diagram of the assembly of the gear box swing gear set of embodiment 2. DETAILED DESCRIPTION

[0012] Some preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0013] Example 1

[0014] As attached Figure 1 A toy gear box with automatic winding and dispensing functions can be used as a core action component for storing toy products such as banknotes, commemorative papers, commemorative tickets, etc., including a shell, a DC motor 1, a roller group, and a gear group.

[0015] The upper ends of the box sheet 2 and the cover sheet 3 constituting the shell form a strip-shaped entrance 4, and the lower end of the box sheet 2 forms an exit 5 downward, and a transmission gear 6 is installed at the exit. The upper and lower parts of the strip-shaped entrance are installed with a roller group consisting of a first roller 7 and a second roller 8. The two rollers are closely attached to form a master-slave connection. The first roller is the driving wheel, and a disc gear 9 is installed on its side end, which meshes with the gear 101 of the winding gear group A. A detection switch 10 is installed on the side of the roller group. When a target enters from the strip-shaped entrance, the DC motor is started to run forward.

[0016] The delivery gear set B meshing with the transmission gear 6 is close to the outlet end, and the transmission gear can be connected with other toy transmission structures outside the gear box. When the transmission gear moves, it drives other structures to deliver the target object stored inside the toy to the outside of the toy.

[0017] The swing gear set C connected to the DC motor includes a fixed wheel 11 and a swing wheel 12, which are connected by a swing rod 13. Figure 2 As shown, the fixed wheel has an upper and lower wheel structure, the upper wheel is meshed with the rotating shaft of the DC motor 1, and the lower wheel is connected to the swing wheel 12. The wheel axle of the fixed wheel is fixed to the box body, and the wheel axle of the swing wheel is inserted into the elliptical swing cavity 14 formed by the box body, and swings in a fan shape under the limit of the swing rod. When the DC motor rotates in the opposite direction under the action of its control switch, it will drive the fixed wheel to rotate in the opposite direction, and push the swing wheel to rotate toward the dispatching gear set B, mesh with the gear of the dispatching gear set, and then link the transmission gear to achieve the dispatching function.

[0018] When this embodiment is used, when a thin sheet-like target object enters the entrance 4, as described above, the DC motor will be started to run forward, driving the fixed wheel to rotate forward, pushing the swing wheel to rotate toward the winding gear set A, meshing with the gear of the winding gear set, and further driving the roller set to rotate, rolling the target object at the entrance into the interior of the toy, realizing the storage function.

[0019] The toy gear box of this embodiment is used as a core component of a children's storage toy, and can be assembled into toy products with various shapes and playing methods.

[0020] Example 2

[0021] As attached Figure 3 As shown, the toy gear box with automatic retracting and dispensing functions of this embodiment has the same basic structure as that of embodiment 1, including a housing, a DC motor 1, a roller set, and a gear set.

[0022] The structure of this embodiment is different from that of the first embodiment in that a right-facing arc groove 20 is formed on the box body of the housing, and the axle of the swing wheel 22 is inserted into the groove. The swing gear set D includes a fixed wheel 21 and a swing wheel 22, and the lower part of the fixed wheel meshes with the swing wheel. The length and position of the arc groove make the swing wheel mesh with the retracting gear set A when it moves to the upper end of the groove, and mesh with the dispatching gear set B when it moves to the lower end of the groove.

[0023] The action effect of this embodiment is the same as that of embodiment 1. Since the arc-shaped groove can also guide the sliding of the swing wheel and selectively drive one of the two gear sets, the forward and reverse rotation of the DC motor drives the winding gear set or the dispensing gear set to move, thereby realizing the storage and dispensing functions.

[0024] The above describes some preferred embodiments of the present invention with reference to the accompanying drawings, but does not mean that it is limited to the structure of the embodiments. All modifications, equivalent substitutions and additions within the technical scope of the claims of the present invention, such as connecting the DC motor and the fixed wheel with a gear plate combination, connecting the rolling wheel and the winding gear set with a worm connection, and other similar structural changes, of course, also belong to the technical scope of the present invention.
