Description

Technical Field

[0001] This invention relates to the field of vending machine technology, specifically to an intelligent vending machine. Background Technology

[0002] The vending process of vending machines is a complex collaborative process involving mechanical, electronic, and software control. Modern vending machines have also incorporated internet platforms for intelligent sales. Different types of intelligent vending machines (such as spring-loaded vending machines, serpentine vending machines, and conveyor belt vending machines) have slight differences in specific operations, but the overall process is similar. Consumers can click on the product display area on the internet sales platform to view the available products. After selecting a product, they can inform the vending machine of the product they want to buy by touching the corresponding product icon on the screen.

[0003] While some existing smart vending machines incorporate internet technology for intelligent sales operations, allowing orders to be placed independently of the machine itself, their dispensing structure is still designed for products with conventional shapes and sizes, such as bottled beverages and canned foods. For irregularly shaped, excessively large, or excessively small items, problems such as jamming or difficulty in dispensing can easily occur. With the integration of internet platforms, smart vending machines can sell an increasingly diverse range of products, extending beyond regular beverages and snacks to include other items such as uniquely shaped toys and oddly packaged gifts. These items are difficult to sell smoothly using existing standard dispensing structures, and each product requires a dedicated drive unit to perform the dispensing operation, making the structural design even more complex to facilitate easy dispensing.

[0004] For example, there are three main types of traditional vending machines: The first is the spring-loaded vending machine. In this type, each lane corresponds to a specific product. When a user selects a product, a motor drives the corresponding spring in the lane to rotate, pushing the product off the spring and onto a slide track to drop into the dispensing slot. This is a push-type release mechanism. Another type is the serpentine vending machine, commonly used for bottled beverages. The dispensing channel is a multi-layered spiral, with products placed inside. During dispensing, a motor drives a pusher plate to push the product from the designated location into the dispensing slot. The last type is the conveyor-mounted vending machine. In this type, products are placed on a conveyor belt. When a dispensing command is received, a motor drives the conveyor belt to transport the selected product to the dispensing slot.

[0005] Of the three traditional dispensing structures mentioned above, the first structure, while simple, relies on a pushing mechanism to release goods, requiring a large number of pushing components. Furthermore, if the pushing stroke is too large, it makes the vending machine more bulky, as larger items require a greater pushing stroke. Since large items already occupy a significant amount of space, the added pushing stroke when all the goods are pushed out and released undoubtedly increases the vending machine's overall size. Moreover, the other two dispensing structures, whether using a spiral dispensing channel or a conveyor belt, also have significant limitations in terms of product size, and their structures are undoubtedly more complex, making them more prone to jamming during transport. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an intelligent vending machine to solve the problems of poor dispensing and limited versatility in existing intelligent vending machines.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: an intelligent vending machine, comprising a plurality of horizontally arranged goods storage compartments located within a cabinet, and an intelligent shopping module integrated into an internet platform. After acquiring shopping information, the intelligent shopping module releases the corresponding goods through a dispensing component. One side of the bottom plate of the goods storage compartment is hinged to the cabinet via a hinged column fixed thereto, so that the bottom plate is cantilevered. The hinged column engages with a latching pin slidably installed within the cabinet to achieve a latching connection, enabling the bottom plate to support the stored goods.

[0010] The shipping assembly includes a rotating rod horizontally installed in the cabinet, capable of rotation and axial movement. Several drive components are spirally arranged along the axial direction of the rotating rod, and all drive components do not overlap on the axial projection of the rotating rod, so that when the rotating rod rotates at an angle, only one drive component can drive its corresponding locking pin to disengage from the hinge post. The bottom plate of the storage compartment is supported by an elastic support member on one side, and the support member can only push the bottom plate to a horizontal position when there is no goods stored on the bottom plate, so as to close the bottom shipping port of the goods storage compartment.

[0011] The rotating rod has several preset rotation angles, each rotation angle corresponding to a product. When the smart shopping module receives a corresponding product purchase order, the rotating rod first rotates by a rotation angle corresponding to the product, and then the rotating rod moves axially by a preset displacement, causing the drive component to disengage the locking pin from the hinge post.

[0012] Furthermore, the rotating rod is rotatably installed inside the crossbeam within the cabinet. The drive assembly includes several push rods spirally arranged along the axial direction of the rotating rod. The projections of all push rods along the axial direction of the rotating rod do not overlap. The crossbeam containing each push rod has a corresponding annular groove, which allows the push rod to rotate with the rotating rod within it. A central hole is provided at the bottom of the annular groove, and all central holes are arranged in the same spiral pattern along the axial direction of the rotating rod. A sliding block is axially elastically slidably installed in the central hole. In the non-working state, one end of the sliding block protrudes from the central hole and extends into the annular groove, so that for each set angle of rotation of the rotating rod, only one push rod and the end of its corresponding sliding block make contact.

[0013] Furthermore, the sliding block includes a slider, a sliding column, and a sliding rod. The slider is slidably installed in the annular groove. The sliding column is used to connect the slider and the sliding rod. A cylindrical spring is sleeved on the sliding rod, with its two ends respectively connected to the bottom of the annular groove and the end face of the slider. One end of the sliding column is located in the middle hole. After the sliding rod slides axially through the middle hole, it can completely push the locking pin out of the hinge column under the push of the top rod.

[0014] Furthermore, a longitudinal beam is fixed perpendicularly to the crossbeam, which separates all the cargo storage compartments. The hinged column is rotatably mounted inside one side of the longitudinal beam, and one end of the column inside the longitudinal beam has a slot for the pin to be inserted.

[0015] Furthermore, a moving block, horizontally slidably mounted within the longitudinal beam, is connected via a return spring. In the non-working state, the moving block is positioned away from the hinge post. A locking pin is coaxially positioned outside the slot opening. The locking pin is fixed to a sliding post via a horizontal connecting rod. One end of the sliding post extends into the mounting slot relative to the hinge post, while its other end connects to a return spring at the bottom of the mounting slot. In the non-working state, the return spring causes one end of the sliding post to protrude from the mounting slot, and the locking pin is inserted into the slot. When the sliding rod pushes the moving block closer to the hinge post, it completely pushes the sliding post back into the mounting slot, causing the locking pin to completely disengage from the slot.

[0016] Furthermore, the lower edge of the end of the moving block away from the hinge post has a chamfered inclined surface, and the slide rod contacts the inclined surface to move the moving block horizontally.

[0017] Furthermore, the end of the slide bar that contacts the inclined surface is a hemispherical surface; a connecting block is fixed on the upper surface of the moving block, and the connecting block is connected to the reset spring.

[0018] Furthermore, the elastic support includes a bearing block fixed on the crossbeam, the bearing block having a receiving cavity inside for rotatably mounting one side of the silo bottom plate; when one side edge of the cavity opening contacts the silo bottom plate, the silo bottom plate is in a horizontal state, and when the other side edge contacts the silo bottom plate, the silo bottom plate is in a vertical state.

[0019] Furthermore, the elastic support also includes a crank rod and a spring. The spring is located within the support block in a bendable manner. The center of the bending direction of the crank rod falls on the axis of the hinge column. One end of the crank rod is always in compressive contact with the bottom plate, and the other end is slidably inserted into the support block and connected to the spring. The spring force can only push the bottom plate to a horizontal state when there is no cargo on the bottom plate.

[0020] Furthermore, the end of the slider that contacts the top rod has rounded corners on both sides; one end of the rotating rod is connected to the main shaft of the drive motor that is vertically slidably mounted on the side of the cabinet, and the main shaft is a telescopic rod.

[0021] (III) Beneficial Effects

[0022] This invention provides an intelligent vending machine. It has the following beneficial effects:

[0023] 1. The intelligent vending machine of this invention has a simple structure and is easy to manufacture. Compared with traditional spring-loaded vending machines, it uses a cantilevered hinged bottom plate, and the dispensing operation is performed by the downward swing of the bottom plate. Compared with pushing, it is easier to make the goods fall, and it undoubtedly greatly reduces the design size of the cabinet thickness. At the same time, a special rotating rod is used to set up a series of push rods in a spiral arrangement, which allows multiple goods storage compartments to be driven by the same drive element to achieve dispensing, eliminating the need to design a dedicated drive unit for each goods storage compartment to perform the dispensing operation.

[0024] 2. The intelligent vending machine of this invention has a large vertical space below the bottom of multiple storage compartments arranged in a straight line as a dispensing channel. It does not require the dispensing channel to be designed as a traditional serpentine or conveyor belt vending machine. The structure is simple, practical and easy to manufacture, thus having greater versatility and facilitating the dispensing of more types of goods.

[0025] 3. Since orders can be placed directly through internet platforms such as mobile phones, there is no need to rely solely on the vending machine's control panel. This effectively avoids the awkward situation where the control panel becomes damaged and unable to process orders due to lack of maintenance or exposure to the outdoors. Furthermore, because this invention is more versatile, it can be adapted to the automatic and rapid dispensing of more types of goods, thus greatly meeting the requirements of a wide range of product categories sold on internet platforms.

[0033] This specification will clearly and completely describe the technical solutions in the following embodiments based on the accompanying drawings. The embodiments described in this specification are only some embodiments of the present invention, not all embodiments. All other embodiments derived by those skilled in the art based on these embodiments without creative effort should fall within the protection scope of the present invention.

[0034] This embodiment describes a smart vending machine, similar to existing smart vending machines, mainly comprising several horizontally arranged goods storage compartments 2 within a cabinet 1. A dispensing slot is located near the bottom of the cabinet 1, typically on the front side near the bottom. This smart vending machine also features a smart shopping module integrated with an internet platform. Consumers can place orders on the corresponding internet shopping platform without needing to operate the control panel on the cabinet 1. This effectively avoids the problem of the control panel easily malfunctioning due to lack of maintenance or exposure to the outdoors. After obtaining the consumer's shopping information through the smart shopping module within the platform, a dispensing component automatically releases the corresponding goods. Specifically, in this embodiment, as shown... Figures 1-4 As shown, one side of the bottom plate 3 of the cargo storage compartment 2, for example, the side facing forward, is hinged to the cabinet 1 by a hinge column 12 fixed thereto. The hinge column 12 can be fixed to the bottom plate 3 as one piece or integrally formed, so that the bottom plate 3 is cantilevered. Specifically, the hinge column 12 is engaged with a latch 13 that is slidably installed in the cabinet 1 to achieve the purpose of cantilevered installation, so that the bottom plate 3 can support and store goods. Once the latch 13 is disengaged from the hinge column 12, the bottom plate 3 will flip downward, thereby releasing the goods and allowing them to roll out from the corresponding channel. Regarding the method of goods rolling out or sliding out of cabinet 1, this embodiment adopts a simplified design. Based on the above-mentioned arrangement of the bottom plate 3, a vertical space can be directly divided within the cabinet 1 space below the bottom plate 3. That is, the vertical space is directly located below the bottom plate 3. All bottom plates 3 share this large vertical space as a channel for transporting goods. This can prevent goods from getting stuck in the outgoing channel, expand the outgoing space, and facilitate unobstructed transport by vertical descent, making it easier for goods to fall directly to the bottom of cabinet 1. Of course, the bottom surface inside cabinet 1 can be a curved surface so that the goods fall as close as possible to the front of the retrieval port for easy retrieval. In use, once the aforementioned bottom plate 3 is flipped downwards and opened, the goods fall into this large, open channel, and then roll or slide to the retrieval port at the bottom of cabinet 1.

[0035] Regarding the structural design logic of the release of cargo by disengaging the locking pin 13 from the hinged column 12, please refer to [link / reference needed]. Figures 1-4 This shipping component may include a horizontally mounted rotating rod 5 within the cabinet 1, capable of rotation and axial movement. Several drive components are spirally arranged along the axial direction of the rotating rod 5, and all drive components do not overlap or intersect on the axial projection of the rotating rod 5. The purpose is to ensure that when the rotating rod 5 rotates at a certain angle, only one drive component can drive its corresponding latch 13 to disengage from the hinge post 12, releasing the goods. Furthermore, as... Figure 6In this embodiment, the bottom plate 3 on one side is supported by an elastic support member. The elastic force of this support member is only sufficient to push the bottom plate 3 to a horizontal position when there is no goods stored on the bottom plate 3, so as to close the bottom outlet of the goods storage compartment 2. This avoids the situation where, if the elastic force is too large, some lighter goods will not be able to be released even if the locking pin 13 is disengaged, and the bottom plate 3 will not be able to swing down to release the goods, resulting in a shipping failure.

[0036] More specifically, in this embodiment, the rotating rod 5 has several preset rotation angles, each rotation angle corresponding to a different item. For example, every 30 degrees of rotation, another item falls from the corresponding bottom plate 3. In use, when the smart shopping module receives a corresponding purchase order, the rotating rod 5, based on the item type information in the order, first rotates by a certain angle. When the rotating rod 5 rotates from its initial position to this angle, it then moves axially by a constant preset displacement, which causes the drive assembly to disengage the locking pin 13 from the hinge post 12.

[0037] As one of the specific design structures, such as Figures 1-2 The rotating rod 5 is rotatably mounted within the crossbeam 4 inside the cabinet 1. The drive assembly includes a plurality of push rods 6 arranged at intervals along a helical path along the axial direction of the rotating rod 5, such as... Figure 6 As shown, the projections of all the push rods 6 onto the axial direction of the rotating rod 5 do not overlap, and each push rod 6 has a corresponding annular groove 21 inside the crossbeam 4. The annular groove 21 allows the push rod 6 to rotate with the rotating rod 5 inside it. A central hole 22 is provided at the bottom of the annular groove 21, and all the central holes 22 are arranged in the same spiral pattern along the axial direction of the rotating rod 5. A sliding block is axially elastically slidably installed in the central hole 22. In the non-working state, one end of the sliding block protrudes outside the central hole 22 and extends into the annular groove 21. This ensures that for each set angle of rotation of the rotating rod 5, only one push rod 6 presses against the end of its corresponding sliding block, releasing the hinge pin 12 of the corresponding cargo bottom plate 3, thereby achieving automatic cargo unloading.

[0038] In this embodiment, as Figure 2 As shown, this sliding block includes a slider 7, a sliding post 8, and a sliding rod 10. The slider 7 is slidably installed in the annular groove 21. The sliding post 8 is used to connect the slider 7 and the sliding rod 10. A cylindrical spring 9 is sleeved on the sliding rod 10, with its two ends connected to the bottom of the annular groove 21 and the end face of the slider 7, respectively, to achieve elastic telescopic installation of the slider 7. In specific manufacturing, one end of the sliding post 8 used to connect the sliding rod 10 can be located in the middle hole 22. After the sliding rod 10 slides axially through the middle hole 22, under the pushing of the top rod 6, the locking pin 13 can be completely pushed out of the hinge post 12, releasing the hinge post 12 and causing the bottom plate 3 to swing down.

[0039] As a specific implementation structure, such as Figure 1 , Figure 2 A longitudinal beam 11 is fixed perpendicularly to the crossbeam 4, separating all the cargo storage compartments 2. A hinged post 12 is rotatably mounted inside one side of the longitudinal beam 11, and the hinged post 12 is located at one end inside the longitudinal beam 11, specifically having a slot 20 for inserting a locking pin 13. A horizontally sliding moving block 17 is also connected within the longitudinal beam 11 via a return spring 19, and in the non-working state, this moving block 17 is positioned away from the hinged post 12. Furthermore, a locking pin 13 is coaxially provided outside the slot 20, and this locking pin 13 is fixed together with a horizontal connecting rod and a sliding post 14, moving together. In this embodiment, the end of the sliding column 14 facing the hinge column 12 normally extends out of its mounting groove 16 to await contact with the moving block 17. The other end of the sliding column 14 is connected to a return cone spring 15 connected to the bottom of the mounting groove 16. In the non-working state, when the return cone spring 15 causes one end of the sliding column 14 to protrude from the mounting groove 16, it must ensure that the locking pin 13 is inserted into the slot 20. That is, in the normal state, the bottom plate 3 is locked. During unloading, the slide rod 10 moves upward to push the moving block 17. When the moving block 17 approaches the hinge column 12, it pushes the sliding column 14 completely back into the mounting groove 16, and causes the locking pin 13 to completely disengage from the slot 20. The bottom plate 3 then automatically opens for unloading. To facilitate the movement of the slider 7, the lower edge of the end of the moving block 17 facing away from the hinge column 12 has a chamfered inclined surface. The slide rod 10 contacts the inclined surface and moves the moving block 17 horizontally.

[0040] As a specific production structure, such as Figure 2 The end of the slide rod 10 that contacts the inclined surface is a hemispherical surface. A connecting block 18 is fixed on the upper surface of the moving block 17. The connecting block 18 is connected to the return spring 19 to achieve an elastic sliding connection.

[0041] As a specific design structure, such as Figure 5 This elastic support includes a bearing block 23 fixed on the crossbeam 4. Specifically, it can be installed at the center of one side of each bottom plate 3. The bearing block 23 has a cavity for rotating one side of the bottom plate 3. During manufacturing, when one edge of the cavity opening contacts the bottom plate 3, the bottom plate 3 is in a horizontal state, i.e., a storage state. When the other edge contacts the bottom plate 3, the bottom plate 3 is in a vertical state, i.e., a shipping state. After the goods fall, the bottom plate 3 automatically flips up and resets under the action of the support, waiting for the goods in the cabinet 1 to be automatically replenished.

[0042] In practice, such as Figure 5This elastic support also includes a crank 24 and a spring 25. The spring 25 is located within the support block 23 in a bendable manner. The center of the bending direction of the crank 24 falls on the axis of the hinge column 12, so that the bottom plate 3 can rotate. One end of the crank 24 is always in compressive contact with the bottom plate 3, and the other end is slidably inserted into the support block 23 and connected to the spring 25, receiving the elastic pushing force from the spring 25. Moreover, the elastic force of the spring 25 can only push the bottom plate 3 to a horizontal state when there is no goods on the bottom plate 3. That is, after the goods are automatically dropped, the bottom plate 3 can be automatically reset and wait for the goods conveying mechanism in the cabinet 1 to automatically replenish the goods.

[0043] In the above embodiments, in order to facilitate the smooth axial movement of the rotating rod 5 after it has rotated to its position, so as to press the slider 7, it is best to process the end of the slider 7 that contacts the push rod 6 as follows: Figure 2 The rounded end faces shown on both sides facilitate the movement and transition of the push rod 6 during compression, forming an arc surface 701. Regarding the axial movement and rotation of the rotating rod 5, as... Figure 1 As shown, one end of the rotating rod 5 can be connected to the main shaft of the drive motor 26, which is vertically slidably mounted on the side of the cabinet 1. Specifically, it can be as follows: Figure 6 As shown, a connecting hole is machined at the end of the rotating rod 5, and a transmission structure such as a keyway is provided on the hole wall to achieve rotation at a corresponding angle. Moreover, the main shaft is a telescopic rod, which can push the rotating rod 5 to move axially automatically after it has been rotated to the correct position. The telescopic rod can be made of electric actuator, hydraulic rod, etc.

[0044] It should be clarified here that, in this specification, terms such as "first" and "second" are merely used to distinguish one feature from another, and do not imply any inherent relationship or order between these technical features. The terms "comprising" and "including" mean that something contains one or more technical means or features, specifically referring to other existing or non-existent technical features not listed above. The descriptions in the above embodiments are merely representative examples for the purposes of this invention and are not the only limiting features. Those skilled in the art should understand that, without departing from the technical content described in all claims of this application, simple substitutions and modifications can be made to create different or equivalent specific embodiments and application scenarios. However, regardless of these adaptive changes, all such embodiments must fall within the protection scope of this invention.
