[0026] This disclosure provides a self-service vending device specifically designed for high-speed rail dining cars, comprising a main body and multiple vending machines. The main body has an inner cavity with a fan-shaped structure whose dimensions gradually increase from back to front. Multiple vending machines are radially distributed within the inner cavity of the main body, with the front ends of two adjacent vending machines forming an installation gap at the front end of the main body. A functional module is installed within this installation gap, connecting two adjacent vending machines and filling the gap. The fan-shaped structure of this self-service vending device fits the limited space of a high-speed rail dining car, and the functional modules integrate multiple practical functions, enhancing the structural stability of the entire device, better resisting vibrations during high-speed rail operation, and preventing the device from loosening or shifting.

[0027] For ease of understanding, specific embodiments of this disclosure are described below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, this disclosure provides a self-service vending device that is only applicable to high-speed rail dining cars 40, including: a main box 10 and a vending machine 20.

[0029] The main housing 10 is constructed with an internal cavity, which is configured as a fan-shaped structure with increasing dimensions from back to front. For example... Figure 3 As shown, due to the limitations of the bar counter 43 and the non-standard geometric space available at the rear of the high-speed rail dining car 40, in order to make full use of the existing bar counter 43's surface and space, the front end of the self-service vending device disclosed herein is installed on the bar counter 43 in the high-speed rail dining car 40, and the bar counter 43 can serve as the main support structure of the self-service vending device. The bar counter 43 is generally arc-shaped, and the front end of the main body 10 is constructed to fit the shape of the bar counter 43. Its rear end is constructed to extend backward from the position of the bar counter 43 and to fit the pointed end of the space at the rear of the bar counter 43. Thus, the main body 10 presents a fan-shaped structure that can match the bar counter 43 and the space at the rear of the high-speed rail dining car 40.

[0030] This fan-shaped structure maximizes the use of the existing structure of the high-speed rail dining car 40, and its shape fits snugly, without encroaching on the aisle area of ​​the dining car 40 or affecting the movement of passengers and train staff. Moreover, the highly fitted shape effectively prevents the self-service vending machines from shifting due to train vibrations during operation, thus avoiding safety hazards caused by equipment displacement.

[0031] The inner cavity of the main body 10 is used to install the vending machine 20 and other modules, which improves the utilization rate of the vertical space of the bar counter 43.

[0032] refer to Figures 1 to 3 Multiple vending machines 20 are arranged radially within the main housing 10, with an installation gap formed at the front end of the main housing 10 between adjacent vending machines 20. Specifically, to improve the utilization rate of the internal space of the main housing 10, multiple vending machines 20 are radially distributed within the internal space based on the fan-shaped structure of the main housing 10, and arranged at the front end of the fan-shaped expansion. This layout allows for the overall miniaturization of the vending device while maximizing the number of vending machines 20.

[0033] The operation interfaces of multiple vending machines 20 extend to the edge of the front end of the main body 10, fitting into the arc-shaped space at the front end of the main body 10, thus forming an installation gap between two adjacent vending machines 20. Multiple vending machines 20 can form multiple installation gaps at intervals, and the resulting installation gap is a fan-shaped space that is narrow at the back and wide at the front.

[0034] To further improve the space utilization of the main housing 10, functional modules are installed within the installation gaps. These modules are designed to connect adjacent vending machines 20 and fill the installation gaps. Multiple vending machines 20 can form multiple installation gaps at intervals. These gaps are not only filled by the functional modules, ensuring the integrity of the vending machine's appearance and dustproof effect, but more importantly, these fan-shaped spaces can be used to integrate various practical functions. Therefore, the functional modules in multiple installation gaps can simultaneously possess multiple functions, including but not limited to support, connection, filling, and control functions. Placing the functional modules at the front end of the installation gaps not only allows the gaps to accommodate the size of the functional modules but also allows the vending machines 20 and functional modules to be connected as a whole. This ensures installation strength while maintaining the overall aesthetic appeal of the front surfaces of the vending machines 20 and functional modules facing the user. Each vending machine 20 and its corresponding functional module can form a relatively independent unit. If a single vending machine 20 or functional module malfunctions, theoretically, maintenance or replacement can be performed on that unit, avoiding the need to dismantle the entire device and significantly reducing maintenance difficulty and time costs. Meanwhile, the modular design also makes it easier to adjust the size of the main unit 10 in the future, and increase or decrease the number of vending machines 20 accordingly.

[0035] In one specific embodiment of this disclosure, the functional module includes a mounting bracket 31 and functional units disposed on the mounting bracket 31. The opposite sides of the mounting bracket 31 are configured to be fixedly connected to the side wall of the corresponding vending machine 20. Specifically, as... Figure 2 As shown, there can be multiple mounting brackets 31, and the structure of multiple mounting brackets 31 can be adapted and adjusted according to different functional units. The mounting brackets 31 can adopt a modular design, and can be assembled from multiple aluminum alloy profiles using screws. The profiles have an I-shaped cross-section for easy screw fixing. The materials selected for the mounting brackets 31 must meet strength and lightweight requirements, but no specific restrictions are imposed in this disclosure. The profiles on both sides of the mounting brackets 31 can be fixedly connected to the side walls of the corresponding vending machine 20 using L-shaped adapter plates, or they can be connected using snap-fit ​​or other connection methods to ensure the stability of the mounting brackets 31.

[0036] In one embodiment of this disclosure, three vending machines 20 are provided, forming two installation gaps between them, denoted as the first installation gap 21 and the second installation gap 22, respectively. The functional unit in the first installation gap 21 is the control screen 321 of the vending machine 20, and the functional unit in the second installation gap 22 is the advertising screen 322. The control screen 321 and the advertising screen 322 fill the installation gaps, eliminating structural redundancy and transforming "useless gaps" into functional panels, thereby improving the space utilization and functional richness of the vending machine.

[0037] Specifically, such as Figure 1 As shown, the control screen 321 can be an embedded panel, seamlessly connected to the mounting bracket 31 of the first mounting gap 21, filling the first mounting gap 21 while maintaining a seamless connection to the end face of the main housing 10. The control screen 321 can have a built-in camera to support facial recognition payment for passengers, and can also be equipped with an infrared sensor to detect when a passenger approaches and wake up the screen of the control screen 321. Passengers can select items from the vending machine 20 through the control screen 321, which can be interacted with via buttons or touch screen.

[0038] Continue to refer to Figure 1 The advertising screen 322 can also be an embedded electronic screen, seamlessly connecting with the mounting bracket 31 of the second mounting gap 22, filling the rectangular front end of the second mounting gap 22 while maintaining the smooth curvature of the front end of the main housing 10. The advertising screen 322 can have a built-in light sensor to automatically adjust brightness, such as increasing brightness in tunnels and switching to a dark mode at night, to avoid glare from the advertising screen 322 affecting passengers' vision and causing safety hazards. The advertising screen 322 has a reserved USB / Type-C interface at the rear for easy offline updates of advertising content.

[0039] In one specific embodiment of this disclosure, such as Figure 1 As shown, the front end of the vending machine 20 is constructed in a rectangular shape. The control screen 321 and the advertising screen 322 are also constructed in a rectangular shape. The opposite sides of the control screen 321 are aligned with the corresponding sides of the vending machine 20; the opposite sides of the advertising screen 322 are aligned with the corresponding sides of the vending machine 20. Specifically, to fit the curved outline edge of the front end of the main housing 10, multiple vending machines 20 with rectangular front ends are arranged radially, and their front ends extend to the edge of the front end of the main housing 10. The two sides of the rectangular control screen 321 and the rectangular advertising screen 322 are strictly fitted to the rectangular outer outline side of the front end of the vending machine 20, so that multiple rectangular planes of the same height smoothly transition at the curved opening at the front end of the main housing 10. The close arrangement of the rectangles on the arc reduces the natural gaps caused by the rectangular units splicing the arc outline, making the overall appearance neat and uniform.

[0040] Continue to refer to Figure 2 In one embodiment of this disclosure, the mounting bracket 31 is constructed in the shape of a rectangular frame, with its side walls inclined to fit against the side walls of the corresponding vending machine 20. Specifically, the rectangular frame of the mounting bracket 31 may be formed by connecting four profile segments to match the rectangular shape of the corresponding functional unit. Figure 4 and Figure 5As shown, the side walls of the mounting bracket 31 on both sides are inclined inward from front to back, and the inclination angle is completely consistent with that of the side wall of the corresponding vending machine 20. This ensures that the mounting bracket 31 and the vending machine 20 are closely fitted and connected, which improves the stability of the mounting bracket 31 and further improves the stability of the corresponding functional unit and the compactness with the vending machine 20.

[0041] In one embodiment of this disclosure, such as Figure 3 As shown, the high-speed rail dining car 40 includes a first aisle 41 and a second aisle 42 connecting two adjacent carriages. It also includes a bar counter 43 located on one side of the first aisle 41. A self-service vending machine is installed on the bar counter 43. The second installation gap 22 is configured to be located away from the first aisle 41 relative to the first installation gap 21. Specifically, the functional unit in the first installation gap 21 is the control screen 321 of the vending machine 20, and the functional unit in the second installation gap 22 is an advertising screen 322, meaning the advertising screen 322 is located away from the first aisle 41. Since the first installation gap 21 is located closer to the first aisle 41, if the advertising screen 322 is located in the first installation gap 21, the light from the advertising screen 322 will extend backward from the side of the first installation gap 21 closer to the first aisle 41, affecting the vision of passengers in the following carriages and causing eye discomfort. Therefore, in order to avoid the light from the advertising screen 322 affecting passengers in the rear carriage, the advertising screen 322 is installed in the second installation gap 22 on the side away from the first aisle 41.

[0042] In one embodiment of this disclosure, the main housing 10 includes a bottom plate 11, a top plate 12 arranged parallel to the bottom plate 11, and side plates 13 located on opposite sides of the bottom plate 11 and the top plate 12; the side plates 13, the top plate 12, and the bottom plate 11 form the inner cavity of the main housing 10; wherein two vending machines 20 are configured to be arranged adjacent to corresponding side plates 13, and another vending machine 20 is configured to be located in the middle of the main housing 10. Specifically, as Figure 2 As shown, the main body 10 includes a top plate 12, a bottom plate 11, and two side plates 13. The top plate 12 and the bottom plate 11 are opposite each other and are fan-shaped. The side plates 13 located on opposite sides between the bottom plate 11 and the top plate 12 are rectangular. The side plates 13, top plate 12, and bottom plate 11 form an inner cavity with a curved opening. The side plates 13, top plate 12, and bottom plate 11 can all be made of thin wood, which reduces the weight of the main body 10 and facilitates shaping and assembly.

[0043] refer to Figure 3The three vending machines 20 are arranged as follows: two vending machines 20 are respectively attached to adjacent opposite side panels 13, and the third vending machine 20 is radially distributed with the two vending machines 20 and located in the middle of the main body 10. This arrangement allows the weight of the vending machines 20 inside the main body 10 to be evenly distributed to the bottom plate 11 of the main body 10, thereby making the surface of the bar counter 43 uniformly stressed and improving the stability of the vending device.

[0044] In one embodiment of this disclosure, such as Figure 2 As shown, at least two reinforcing beams 14 are provided at the top of the top plate 12 and / or the bottom of the bottom plate 11. These at least two reinforcing beams 14 are configured to extend from the front end of the main housing 10 towards its rear end. Specifically, the reinforcing beams 14 are connected to the top of the top plate 12 of the main housing 10 by screws, with multiple screws evenly distributed and connecting the top plate 12 and the reinforcing beams 14. The at least two reinforcing beams 14 extend from the front end of the main housing 10 towards its rear end, as shown... Figure 1 and Figure 2 As shown, one end of a reinforcing beam 14 is connected to the top of the top plate 12, above the second mounting gap 22, and the other end extends towards the rear end of the top plate 12 to the top of the side plate 13 on one side; one end of another reinforcing beam 14 is connected to the top of the top plate 12, above the first mounting gap 21, and the other end is also connected to the rear end of the top plate 12, above the side plate 13 on the same side. The extension directions of the two reinforcing beams 14 can intersect at the center of the arc shape of the main box 10, that is, the two reinforcing beams 14 extend from the front end of the main box 10 along the radial direction of the main box 10, which plays a role in improving the stability of the main box 10.

[0045] Similarly, the reinforcing beam 14 is connected to the bottom of the base plate 11 of the main housing 10 by screws. Multiple screws can be evenly distributed and connect the base plate 11 to the reinforcing beam 14. At least two reinforcing beams 14 extend from the front end to the rear end of the main housing 10, such as... Figure 2 As shown, one end of a reinforcing beam 14 is connected to the bottom of the base plate 11, below the second mounting gap 22, and the other end extends towards the rear end of the base plate 11 to the bottom of the side plate 13 on one side; one end of another reinforcing beam 14 is connected to the bottom of the base plate 11, below the first mounting gap 21, and the other end is also connected to the rear end of the base plate 11, below the side plate 13 on the same side. The extension directions of the two reinforcing beams 14 can intersect at the center of the arc shape of the main box 10, that is, the two reinforcing beams 14 on the base plate 11 extend from the front end of the main box 10 along the radial direction of the main box 10.

[0046] At the same time, at least two reinforcing beams 14 are respectively provided at the top of the top plate 12 and the bottom of the bottom plate 11, such as Figure 2As shown, two reinforcing beams 14, which are fixed to the top of the top plate 12 by evenly distributed screws, extend in the radial direction of the main box 10. Two reinforcing beams 14, which are fixed to the bottom of the bottom plate 11, also extend in the radial direction of the main box 10, further reinforcing the main box 10, improving the stability and robustness of the main box 10, and effectively resisting the vibration environment during train operation.

[0047] In one embodiment of this disclosure, the front end of the vending machine 20 is configured to be located at the edge of the front end of the main housing 10, and its orthographic projection in the vertical direction is within the orthographic projection range of the main housing 10 in the vertical direction. Specifically, as Figure 1 As shown, the operation interfaces of multiple vending machines 20 extend to the edge of the front end of the main unit 10, but do not exceed the edge of the front end of the main unit 10, fitting into the curved space at the front end of the main unit 10. This layout naturally faces the operation interfaces, such as the windows and dispensing slots of the vending machines 20, towards the passengers. Passengers do not need to move significantly or turn sideways; they can easily see and reach the operation interfaces and dispensing slots of multiple vending machines 20 within a small area in front of the device, resulting in a smoother operation path and easier discovery and use of the interfaces. Additionally, it avoids the front end of the vending machines 20 excessively encroaching on the aisle space.

[0048] In one embodiment of this disclosure, such as Figure 3 As shown, the inner cavity of the main housing 10, located at the rear of the vending machine 20, forms a space for housing the control unit. Specifically, as... Figure 6 As shown, multiple vending machines 20 occupy the fan-shaped space at the front of the main housing 10, leaving space at the pointed area at the rear of the main housing 10 free to house a control unit. This control unit can be configured to have multiple control modules. The space at the rear of the main housing 10 where the control unit is located can also be fitted with an independent door to prevent maintenance of the control unit from interfering with front-end vending services. (Reference) Figure 3 The front ends of the three vending machines 20 are unfolded inside the main housing 10, and their rear ends are arranged adjacent to each other, so that the rear end of the chamber forms a space for placing the control unit, which is beneficial for the installation and maintenance of the wiring harness and control unit.

[0049] The control unit transcends the traditional "controller" category in its functions, becoming the core hub of the digital self-service system in the high-speed rail dining car 40, balancing efficiency, safety, and scalability. The control unit integrates control of multiple vending machines 20 and multiple functional units, including but not limited to: controlling the startup, hibernation, fault diagnosis, and switching of operating modes of multiple vending machines 20, such as single-machine maintenance mode and cluster linkage mode; By controlling the functional modules (such as sensors and payment terminals) within the installation gaps to acquire data in real time, the product inventory allocation and replenishment prompts of adjacent vending machines 20 are dynamically adjusted. The control unit supports cross-screen collaboration. After passengers select items on the control screen 321, they can be assigned to any available vending machine 20 for dispensing, thus optimizing queuing efficiency. The control unit integrates the operation screen of the self-service vending machine 20, the advertising screen 322 (playing public service advertisements or promotional information, etc.), and the auxiliary display screens of the functional modules (such as payment guidance and pickup prompts), so as to realize the synchronous operation of content or the independent operation of split screens; The control unit supports voice prompts for transaction status and alarms for operational errors (such as banknote jamming, out-of-stock items, etc.), and is adapted to the noise environment of high-speed rail. When handling abnormal transactions, the control unit can automatically identify faults such as payment timeout and delivery failure, and activate backup channels or notify manual intervention. The control unit can also dynamically adjust screen brightness and standby power consumption based on passenger flow, and supports low power consumption mode (such as night shifts). Meanwhile, the control unit can be equipped with temperature sensors and vibration sensors. The temperature sensor monitors the heat dissipation status of the main housing 10 cavity (to prevent the motor from overheating), and the vibration sensor detects the stability of the equipment during high-speed train operation and triggers the vibration reduction mechanism. The control unit should also have network interconnection capabilities, uploading sales data to the railway operation and maintenance center via a 4G / 5G module; a local Wi-Fi hotspot for passengers to check order information; and edge computing capabilities to temporarily store transaction data when the network is down, and automatically synchronize it after the network is restored to avoid data loss.

[0050] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments.
