Description

Technical Field

[0001] This utility model relates to the field of entertainment and interactive equipment technology, and more particularly to a ball-shaking device with a ball-returning mechanism, which can be widely used in scenarios such as amusement lottery, experimental ball mixing, and small material sorting. Background Technology

[0002] Existing ball-shaking devices suffer from the following key structural and operational issues, making it difficult to meet functional requirements:

[0003] The mixing structure has a simple principle: it mostly adopts the structure of "static containment + manual shaking" or "simple motor driving blades", lacking the transmission design of "active material feeding + anti-accumulation". Small balls are prone to accumulate at the bottom of the containment space due to gravity, and cannot achieve uniform mixing through structural transmission, resulting in insufficient randomness.

[0004] The ball return structure lacks a guiding principle: after the ball is ejected, there is no "directional flow" structure, and it relies mostly on free rolling. It cannot form a "flow-detection" structural cooperation with the detection component, resulting in low recognition accuracy.

[0005] The human-computer interaction structure has no linkage principle: the operating parts and the stirring parts have no mechanical or electronic linkage structure, the stirring intensity is fixed, the user operation cannot be converted into the adjustment of stirring parameters, and the sense of interaction is weak.

[0006] The loop structure lacks a closed-loop principle: after recognition, the ball needs to be manually retrieved. It lacks a closed-loop structure of "return channel - containment space", which cannot achieve automatic circulation and is not suitable for continuous scenarios. Utility Model Content

[0007] The purpose of this invention is to overcome the defects of uneven mixing, disordered conveying, low recognition accuracy and lack of interactivity in the existing technology, and to provide a mixing-type ball shaking device that is compact in structure, easy to operate and adaptable to multiple scenarios.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A ball-shaking device with a ball-returning mechanism, comprising:

[0010] substrate;

[0011] A ball-shaking mechanism fixed on the substrate forms a ball-accommodating space and actively stirs the ball, and has an inlet and an outlet that cooperate with the ball-returning mechanism;

[0012] A ball return mechanism connected to the ball shaking mechanism is used to realize the orderly delivery and identification of small balls;

[0013] The hand-cranked unit is disposed on the substrate and is used to realize human-computer interaction and control the stirring intensity of the ball shaking mechanism;

[0014] And a blocking mechanism that cooperates with the ball return mechanism to block and release the ball within the ball return mechanism;

[0015] The components work together to achieve the functions of stirring, conveying and circulating the small balls.

[0016] Furthermore, the ball-shaking mechanism includes a receiving structure that constitutes the ball-containing space, and a stirring assembly that drives the ball to stir; the inlet of the receiving structure allows the ball to enter the return ball mechanism from the receiving space, and the outlet allows the ball to enter the receiving space from the return ball mechanism; the stirring assembly includes a driving member and a stirring member that is pulsatingly connected to the driving member, and the stirring member extends into the receiving space to achieve the lottery by stirring the ball.

[0017] Furthermore, the receiving structure includes a rocking ball base fixed on the substrate and a rocking ball cover fixedly connected to the rocking ball base; the rocking ball cover is made of transparent material to observe the state of the small ball in the receiving space; the inlet is located on the high side of the rocking ball base, and the outlet is located on the low side of the rocking ball base.

[0018] Furthermore, the driving component of the stirring assembly is a stirring motor, and the stirring component is a stirring lever; the stirring motor is fixed on the base plate, and its output shaft extends through the rocker ball base into the receiving space, and its end is connected to the stirring lever for transmission, driving the stirring lever to rotate in the receiving space to agitate the small ball; the end of the stirring lever is connected to a stirring plate.

[0019] Furthermore, the ball return mechanism includes a channel body for the flow of the ball and a sensing component for detecting the ball; the bottom wall of the channel body has an inclined structure, and the ball flows automatically along the inclined structure by gravity, with one end connected to the inlet of the ball shaking mechanism and the other end connected to the outlet of the ball shaking mechanism; the sensing component includes a first sensor for detecting whether the ball has entered the channel body and a second sensor for identifying the characteristics of the ball.

[0020] Furthermore, the main body of the channel has a meandering structure, including a ball-receiving channel connected to the inlet of the ball-shaking mechanism and a circulation channel connected to the outlet of the ball-shaking mechanism; the ball-receiving channel is located directly above the circulation channel and the two are interconnected; the first sensor is disposed at the end of the ball-receiving channel and the second sensor is disposed at the end of the circulation channel; the first end of the ball-receiving channel extends into the receiving space through the inlet, and the extended end has an upward opening, the inlet diameter being adapted to the diameter of the small ball.

[0021] Furthermore, the first sensing element is an infrared beam sensor; the second sensing element is a color sensor for identifying the color characteristics of the ball; after the first sensing element detects the ball, it triggers the blocking mechanism to act, and after the second sensing element identifies the characteristics of the ball, it is used to determine the reward target or sorting category.

[0022] Furthermore, the blocking mechanism includes a drive source, a blocking component, and a transmission mechanism connecting the drive source and the blocking component;

[0023] The driving source is a blocking motor, the blocking component is a blocking rod, and the transmission mechanism includes a crank and a connecting rod.

Its output shaft is fixedly connected to one end of the crank, and the other end of the crank is rotatably connected to one end of the connecting rod. The other end of the connecting rod is in transmission engagement with the upper end of the blocking rod. The middle part of the blocking rod is rotatably mounted on the rear side of the circulation channel via a rotating shaft. Its lower end is integrally formed with a blocking part, and a blocking opening is formed on the rear side of the circulation channel. The driving source drives the blocking part of the blocking rod to extend into or out of the circulation channel through the blocking opening via the transmission mechanism. When it extends into the channel, it blocks the ball, and when it exits, it allows the ball to pass through, ensuring that the ball passes through the channel body in an orderly manner and is recognized by the sensing component.

[0024] Furthermore, the hand-cranked unit includes an operating component for user operation, a backstop structure to limit the reverse rotation of the operating component, and a third sensor for detecting the operating parameters of the operating component; the third sensor is electrically connected to the stirring component drive of the ball-cranking mechanism, and converts the detected operating parameters into control signals to adjust the stirring intensity of the stirring component.

The third sensor is a Hall angle sensor, which is electrically connected to the stirring assembly drive via a controller. The controller converts the operating parameters detected by the third sensor into control signals to achieve linkage between the operating speed of the operating component and the stirring speed of the stirring assembly.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] like Figure 1-6 As shown, the system includes a base plate 1, a ball-shaking mechanism 2, a ball-returning mechanism, a hand-cranked unit 3, and an obstruction mechanism 29. The structure and principle of each module are as follows:

[0039] 1. Basic support module: base plate 1

[0040] Structural design: The structure is made of stainless steel and has reserved mounting holes for the ball-shaking mechanism 2 and the hand-cranked unit 3.

[0041] Principle and function: As a fixed foundation for all functional modules, the rigidity of the material ensures the stability of the overall structure, avoids positional displacement caused by vibration during module operation, and provides a benchmark for the structural coordination of each module.

[0042] 2. Stirring function module: Shaking ball mechanism 2

[0043] Structural components: including a containment structure to achieve "small ball containment" and a stirring component to achieve "active stirring";

[0044] The container structure consists of a ball-shaking base 21 and a ball-shaking cover 22. The ball-shaking base 21 is designed as a "circular disc with a height difference" (the high side has an inlet 25 and the low side has an outlet 26), which uses the principle of gravity to guide the small balls 4 to flow towards the outlet 26. The ball-shaking cover 22 is a transparent hemispherical structure that is detachably connected to the ball-shaking base 21, forming a closed container space and facilitating observation of the internal stirring state.

[0045] The stirring assembly consists of a stirring motor 23, a stirring lever 24, and a coupling. The stirring motor 23 is fixed below the base plate 1, and its output shaft is connected to the stirring lever 24, which extends into the receiving space, via a coupling.

[0046] Principle and function: The stirring motor 23 transmits power to the stirring lever 24 through the coupling, causing the lever to rotate. The "mechanical actuation" principle breaks the gravity accumulation of the small balls 4, achieving uniform mixing. At the same time, the thrust generated by the rotation of the lever assists the small balls 4 to move towards the outlet 26 along the height difference of the ball-shaking chassis 21, providing initial power for the subsequent ball return process.

[0047] 3. Conveying and Identification Module: Ball Return Mechanism

[0048] Structural components: including the main channel body that enables "orderly transport" and the sensing components that enable "precise detection";

[0049] The main channel consists of a ball-receiving channel 27 and a circulation channel 28, both designed as "channels with slopes". The ball-receiving channel 27 is inclined to connect the outlet 26 of the ball-shaking mechanism 2 to the circulation channel 28, and the circulation channel 28 is circuitously connected to the ball-receiving channel 27 and the inlet 25 of the ball-shaking mechanism 2. The inner walls of the channels are all designed as smooth slopes, so that the small ball 4 can flow automatically without additional power by utilizing the principle of gravity.

[0050] Sensing components include a first sensor 5 (infrared beam sensor) and a second sensor 6 (color sensor); the first sensor 5 is installed at the junction of the ball receiving channel 27 and the circulation channel 28, and the second sensor 6 is installed at the junction of the circulation channel 28 and the inlet 25.

[0051] Principle and function: After ball 4 enters ball receiving channel 27 from exit 26, it slides down the inclined plane to the connection point by gravity, triggering the "beam blocking" detection of the first sensor 5, which determines that ball 4 has entered the circulation channel 28; ball 4 continues to slide down the inclined plane of circulation channel 28 to the second sensor 6, where the characteristics of ball 4 (such as color corresponding to reward level) are identified through the "color reflection light detection" principle, realizing the structural linkage of "conveying-identification".

[0052] 4. Human-computer interaction module: Hand-cranked unit 3

[0053] Structural components: including a joystick 31 for "user operation", a backstop structure (ratchet 33, pawl 34) for "anti-reverse operation", and a third sensing element 36 (Hall angle sensor) for "parameter detection".

[0054] Operation and anti-reverse structure: The rocker arm 31 is connected to the first frame 32 via a bearing and can rotate 360°; the ratchet 33 is fixed on the axial rod of the rocker arm 31, and the pawl 34 is hinged to the first frame 32 via a spring, forming a "one-way engagement" structure;

[0055] Detection structure: The third sensing element 36 is mounted on the second frame 35, directly opposite the axial end of the rocker arm 31;

[0056] Principle and function: When the user rotates the joystick 31, the ratchet 33 rotates synchronously with the joystick. The pawl 34 engages with the ratchet 33 in one direction through the spring force to prevent the joystick from rotating in the opposite direction and ensure operational stability. At the same time, the third sensor 36 detects the rotation speed of the joystick 31 through the "Hall effect", converts the mechanical operation parameters into electrical signals, and transmits them to the controller of the stirring motor 23 to realize the linkage control of "user operation speed - stirring motor speed", so that the user operation directly affects the stirring intensity.

[0057] 5. Orderly Control Module: Barrier Mechanism 29

[0058] Structural components: including a blocking motor 291 that realizes "power output", a transmission structure (crank rod 292, connecting rod 293) that realizes "motion conversion", and a blocking rod 295 (with blocking part 297) that realizes "blocking / releasing". The blocking motor 291 is fixed to the rear side of the rocker base 21, and the output shaft is connected to the crank rod 292. The crank rod 292 is linked to the transmission part 294 at the upper end of the blocking rod 295 through the connecting rod 293. The transmission part 294 has an elongated hole along its length direction. The end of the connecting rod 293 is movably engaged with the elongated hole. The blocking rod 295 is hinged to the rear side of the circulation channel 28 through the rotating shaft 296. The lower blocking part 297 corresponds to the blocking opening 281 of the circulation channel 28.

[0059] Principle and function: When the first sensor 5 detects the ball 4, the controller triggers the blocking motor 291 to rotate. Through the "crank-connecting rod transmission" principle, the rotational motion of the motor is converted into the swing of the blocking rod 295 around the rotating shaft 296, causing the blocking part 297 to exit from the blocking opening 281 and allowing the ball 4 to pass. After the ball 4 passes, the blocking motor 291 rotates in the opposite direction, driving the blocking part 297 to re-enter the opening and block subsequent balls 4, ensuring that only a single ball 4 passes through the circulation channel 28 at any time, avoiding congestion of multiple balls that may affect the recognition accuracy of the second sensor 6.

[0060] 6. Principle of Overall Collaboration

[0061] Each module forms a functional closed loop through structural connections: the user shakes the rocker arm 31 → the third sensor 36 detects the rotation speed → controls the stirring motor 23 to drive the stirring lever 24 to stir → the small ball 4 enters the ball return mechanism from the outlet 26 → the ball receiving channel 27 is conveyed on an inclined plane → the first sensor 5 detects and triggers the blocking mechanism 29 to release the ball → the circulation channel 28 is conveyed on an inclined plane → the second sensor 6 identifies the ball → the small ball 4 returns to the receiving space from the inlet 25 → the blocking mechanism 29 resets, completing one "stirring-conveying-identifying-circulation" process.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0063] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
