Description

Technical Field

[0001] This disclosure relates to the field of high-speed railway equipment technology, specifically to a self-service machine system. Background Technology

[0002] In high-speed rail operations, dining cars, as service carriages, must balance space utilization, passage requirements, and operational convenience. However, the current development of self-service machine systems faces three major bottlenecks: First, dining car space is limited and non-standard. Traditional rectangular self-service machines are difficult to fit into existing structures, easily wasting space or encroaching on passageways. Furthermore, the need to avoid altering the original dining car structure presents a lack of designs suitable for special shapes. Second, the vibrations during high-speed rail operation require stable support for the self-service machines, necessitating regulations strictly prohibiting damage to the dining car structure. Traditional fixing methods are unsuitable, and there is currently no solution that balances stability with non-destructive disassembly. Third, self-service machines need to integrate multiple modules. The narrowness of the dining car leads to a compact layout, and vibrations further increase the risk of malfunctions. Existing equipment does not incorporate optimized layout and positioning based on the dining car structure. In conclusion, there is an urgent need to develop an overall structure for self-service machines that can precisely integrate with high-speed rail dining cars, possessing special shapes, stable support, and non-destructive installation characteristics.

[0026] This disclosure provides a self-service machine system applicable to various types of high-speed rail dining cars. The high-speed rail dining car includes a floor, a bar counter supported on the floor, a first limiting structure, and a second limiting structure, which together form an open end. The self-service machine system includes a self-service cabinet. The front of the self-service cabinet rests on the bar counter and protrudes from the open end, while the rear is supported on the floor by a first column, maintaining its own stability while distributing its weight to the bar counter and the floor. Furthermore, both ends of the self-service cabinet can respectively cooperate with the first and second limiting structures, further enhancing its stability. In practical applications in various types of high-speed rail dining cars, the self-service machine system demonstrates strong adaptability, good stability, convenient and cost-effective installation, and its functions can be expanded and adjusted.

[0027] The specific embodiments of this disclosure are described below with reference to the accompanying drawings.

[0028] This disclosure provides a self-service machine system configured to be used only in a high-speed rail dining car 1. (Reference) Figures 1 to 3 The high-speed rail dining car 1 includes a floor 16 and a bar counter 11 supported on the floor 16. It also includes a first limiting structure 12 located on one side of the bar counter 11 and a second limiting structure 13 located on the other side of the bar counter 11. The bar counter 11, the first limiting structure 12, and the second limiting structure 13 together form an open end 14.

[0029] Specifically, the high-speed rail dining car 1 may have different designs depending on the train model and formation. This disclosure uses the illustrated high-speed rail dining car 1 as an example for explanation. Figure 1 As shown, the high-speed rail dining car 1, as a service-type carriage in a high-speed train, has a non-removable existing structure including a floor 16, a bar counter 11, a first limiting structure 12, and a second limiting structure 13. The first limiting structure 12 and the second limiting structure 13 can be columns in the dining car, cabinets with specific functions such as storage cabinets, or even the walls of the dining car, all supported by the floor 16. The bar counter 11 is generally arc-shaped, with the first limiting structure 12 and the second limiting structure 13 located on either side of it, facilitating train staff to stand behind the bar counter 11 to provide train service to passengers. Therefore, the bar counter 11, the first limiting structure 12, and the second limiting structure 13 are connected, together forming an opening 14 similar to a service window of the bar counter 11, providing interactive functionality.

[0030] The self-service machine system disclosed herein includes a self-service cabinet 2. To adapt to the existing structure of the high-speed rail dining car 1, the self-service cabinet 2 is composed of a frame, a base plate, and a top plate structure, which are fixedly connected to form a three-dimensional structure with a cavity and an overall fan shape. The frame of the self-service cabinet 2 can be made of lightweight aluminum alloy or other materials, and this disclosure does not impose any restrictions. Such material selection ensures support strength while reducing weight, facilitating installation and maintenance in the confined environment of the dining car.

[0031] like Figure 3 As shown, the two opposite ends of the self-service cabinet 2 are designated as the first end 21 and the second end 22, respectively. The front of the self-service cabinet 2 rests on the bar counter 11 and protrudes from the opening end 14, while the rear of the self-service cabinet 2 is supported on the floor 16 by the first column 31.

[0032] Specifically, when a high-speed train operating long distances is converted to short-distance operations, in order to save labor costs, a self-service cabinet 2 is installed on the original bar counter 11 in the dining car, transforming it into a self-service machine system. The fan-shaped self-service cabinet 2 is placed on the curved bar counter 11, so that the weight of the front side of the self-service cabinet 2 is distributed on the bar counter 11. The shape of the front side of the self-service cabinet 2 matches the curvature of the bar counter 11, and it just protrudes from the opening end 14 and seals the opening end 14.

[0033] To improve the utilization rate of the internal space of self-service locker 2, several vending machines and other modules can be installed in the chambers within self-service locker 2. (Reference) Figure 1 Based on the fan-shaped structure of self-service cabinet 2, these vending machines are radially distributed within the chamber of self-service cabinet 2, arranged at the front end of the fan-shaped expansion. This layout allows for the overall miniaturization of the self-service machine system while maximizing the number of vending machines. Consequently, installation gaps are formed between adjacent vending machines, and multiple vending machines can be spaced out to create multiple installation gaps, forming a fan-shaped space that is narrower at the back and wider at the front.

[0034] To further improve the space utilization of the two chambers of the self-service vending machine, functional modules are installed within the installation gaps. These modules are designed to connect adjacent vending machines and fill the gaps. Multiple vending machines can be spaced out to form multiple installation gaps. 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 the multiple installation gaps can simultaneously possess multiple functions, including but not limited to support, connection, filling, and control functions.

[0035] Placing the functional modules at the front end of the installation gap not only allows the gap to accommodate the module's dimensions but also integrates the vending machine and module seamlessly. This ensures installation strength while maintaining a cohesive look for the user-facing vending machine and module. Each vending machine and its corresponding functional module can form a relatively independent unit. In the event of a malfunction in a single vending machine or module, maintenance or replacement can theoretically be performed on that unit, avoiding the need to dismantle the entire device and significantly reducing maintenance difficulty and time costs. Furthermore, the modular design facilitates future adjustments to the dimensions of the vending machine cabinet 2, allowing for adjustments to the number of vending machines.

[0036] In one specific embodiment of this disclosure, the functional module includes a mounting bracket and functional units mounted on the mounting bracket. The opposite sides of the mounting bracket are configured to be fixedly connected to the side walls of the corresponding vending machine. Specifically, there can be multiple mounting brackets, and the structures of these brackets can be adapted and adjusted according to different functional units. The mounting bracket can adopt a modular design, and can be constructed from multiple aluminum alloy profiles assembled with screws. The profiles have an I-shaped cross-section for easy screw fixing. The materials selected for the mounting bracket must meet strength and lightweight requirements, but this disclosure does not impose specific limitations. The profiles on both sides of the mounting bracket can be fixedly connected to the side walls of the corresponding vending machine using L-shaped adapter plates, or they can be connected using snap-fit ​​or other connection methods to ensure the stability of the mounting bracket.

[0037] In one specific embodiment of this disclosure, three vending machines can be installed, forming two installation gaps between them, denoted as the first installation gap and the second installation gap, respectively. The functional unit in the first installation gap is the control screen of the vending machine, and the functional unit in the second installation gap is an advertising screen. The control screen and advertising screen 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.

[0038] Specifically, the control screen can be an embedded panel that seamlessly connects with the mounting bracket in the first installation gap, filling the gap while maintaining a seamless connection to the front end of the self-service cabinet 2. The control screen 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 activate the screen. Passengers can select items from the vending machine through the control screen, which can be interacted with via buttons or a touchscreen.

[0039] The advertising screen can also be an embedded electronic screen, seamlessly connecting with the mounting bracket in the second installation gap, filling the rectangular front end of the second installation gap while maintaining the smooth curvature of the front surface of the self-service cabinet 2. The advertising screen can have a built-in light sensor to automatically adjust the brightness, such as increasing brightness in tunnels and switching to a dark mode at night, to avoid the safety hazards caused by glare from the advertising screen affecting passengers' vision. A USB / Type-C interface is reserved at the rear of the advertising screen for easy offline updates of advertising content.

[0040] The rectangular control screen and rectangular advertising screen are perfectly aligned with the rectangular outer contour of the front of the vending machine, ensuring a smooth transition between multiple rectangular planes of the same height in front of the vending machine 2. The close arrangement of the rectangles on the arc reduces the natural gaps created by the overlapping of the rectangular units, resulting in a neat and unified overall appearance and forming an arc-shaped front face at the front of the vending machine 2.

[0041] Combination Figure 1 and Figure 3 The front of the self-service cabinet 2 is supported by the bar counter 11, and the rear is supported by the first column 31 on the floor 16, forming a "front-rear" two-way load-bearing system. This system distributes the weight of the self-service cabinet 2 and the internal equipment to the two load-bearing structures of the food cart floor 16 and the bar counter 11, avoiding excessive stress at a single point that could damage the existing structure of the food cart and preventing the self-service cabinet 2 from tilting or shifting.

[0042] like Figure 3 As shown, the rear side of the self-service cabinet 2 forms a fan-shaped apex area. A first column 31 is located at the bottom of the rear side of the self-service cabinet 2, extending from the bottom of the self-service cabinet 2 to support the floor 16. Through the first column 31, the weight of the rear side of the self-service cabinet 2 can be distributed on the floor 16, preventing the self-service cabinet 2 from shaking. The first column 31 can adapt to the limited space on the high-speed rail dining car 1 and can be constructed as an irregular column. The material of the first column 31 can also be lightweight aluminum alloy or other materials, and this disclosure does not impose any restrictions. Optionally, the first column 31 can be set as a cabinet-type column with internal space. A door is provided on the rear side of the first column 31 for easy adjustment and maintenance during use, and it can also be used as a temporary storage cabinet.

[0043] According to high-speed rail operation regulations, the existing structure of the high-speed rail dining car 1 cannot be altered, nor can holes be drilled in it. When the high-speed train is in motion, conventional self-service kiosks may pose a safety hazard due to their inability to be secured. In the event of emergency braking, they may tip over due to inertia, potentially injuring passengers. Therefore, the self-service machine system provided in this disclosure must balance stability and non-destructive disassembly, precisely integrating with the existing structure of the high-speed rail dining car 1 to achieve stability. Figures 1 to 3 As shown, the first end 21 of the self-service cabinet 2 cooperates with the first limiting structure 12, and its second end 22 cooperates with the second limiting structure 13, forming an irregular fan-shaped structure. The front of the self-service cabinet 2 is supported on the bar counter 11, and its rear pointed area is supported on the floor 16 by the first column 31 to keep it horizontal, and cooperates with the first limiting structure 12 and the second limiting structure 13 respectively, so that it will not move left or right under the vibration of the train during operation. The fan-shaped design of the self-service cabinet 2 is not a simple choice of geometric shape, but a reverse customization based on the existing parameters such as the arc contour of the bar counter 11 of the high-speed rail dining car 1 and the distance between the first and second limiting structures 13. The arc of the fan shape and the length difference between the first end 21 and the second end 22 are precisely matched with the curvature of the bar counter 11 and the spacing of the limiting structures, ensuring that the self-service cabinet 2 can be embedded in the space enclosed by the bar counter 11 and the two limiting structures, without encroaching on the passenger passage, maximizing the use of the idle area of ​​the food cart, and ensuring that the part of the front of the self-service cabinet 2 exposed from the opening end 14 meets the requirements of the passenger's operating height and interaction distance.

[0044] In one embodiment of this disclosure, the rear end of the fan-shaped self-service cabinet 2 forms a pointed area, and the first column 31 is configured to connect to the pointed area. The self-service cabinet 2 has an openable cabinet door on its rear side. In the space outside the bar counter 11, the irregular fan-shaped structure ensures that the opening and closing of the cabinet door is not affected, facilitating the daily maintenance of the vending machine inside the self-service cabinet 2.

[0045] In one embodiment of this disclosure, such as Figure 7 As shown at point C, there is a gap between the second end 22 of the self-service cabinet 2 and the first end face 131 corresponding to the second limiting structure 13, and the gap between the front side of the second end 22 and the first end face 131 is greater than the gap between the rear side of the second end 22 and the first end face 131. This results in a gap that gradually increases from front to back between the self-service cabinet 2 and the second limiting structure 13, preventing the second end 22 of the self-service cabinet 2 from directly engaging with the second limiting structure 13. Therefore, a connecting plate 33 extending horizontally is provided at the top and / or bottom of the second end 22 of the self-service cabinet 2. The connecting plate 33 abuts against the first end face 131 of the second limiting structure 13 and is constructed as a surface fit.

[0046] Specifically, refer to Figure 3 and Figure 4 Because the self-service cabinet 2 has a fan-shaped structure and its front dimension is larger than its rear dimension, its second end 22 is inclined. To enable the second end 22 of the self-service cabinet 2 to fit with the second limiting structure 13, a connecting plate 33 is designed according to the gap characteristics. The connecting plate 33 is fixed to the top of the self-service cabinet 2 with screws and is a horizontal extension of the self-service cabinet 2. The connecting plate 33 can be a grooved plate with at least five end faces, wider at the front and narrower at the back. It abuts against the first end face 131 of the second limiting structure 13 through a surface fit, compensating for the gap width between the self-service cabinet 2 and the second limiting structure 13.

[0047] Similarly, a connecting plate 33 can also be provided at the bottom of the self-service cabinet 2, which is fixed to the bottom of the self-service cabinet 2 by screws. The connecting plate 33 at the bottom of the self-service cabinet 2 can be a non-standard grooved plate with different folding directions on each end face, and an overall shape that is wider at the front and narrower at the back, which abuts against the first end face 131 of the second limiting structure 13 through a surface fit. The connecting plate 33 can be provided at both the top and bottom of the self-service cabinet 2, or only at the top or bottom of the self-service cabinet 2, depending on the actual installation situation, and the length and width of the connecting plate 33 can be adapted to the actual installation gap of different models of high-speed rail dining cars 1. In addition, the material of the connecting plate 33 can be selected to have both hardness and light weight, which can resist the inertial force of the self-service cabinet 2 during train operation and maintain the stability of the self-service cabinet 2 without deformation.

[0048] In addition, the surface of the connecting plate 33 that contacts the first end face 131 can be treated with frosting or other methods to increase the coefficient of friction and further restrict the sliding of the self-service cabinet 2 in the horizontal direction.

[0049] In one embodiment of this disclosure, the front side of the first end face 131 extends toward the self-service cabinet 2 to form an extension 132, and the extension 132 participates in forming the opening end 14. Figure 2 As shown, the extension 132 extends from the front side of the first end face 131 of the second limiting structure 13 towards the self-service cabinet 2 to the position of the opening end, forming a right-angle structure, that is, its cross-section is "L" shaped. On the one hand, it helps to form the opening end 14, and on the other hand, it forms a "longitudinal limit" on the self-service cabinet 2.

[0050] like Figure 3 As shown, the front side of the second end 22 of the self-service locker 2 is constructed to form a notch 23 that mates with the extension 132. The front side of the second end 22 of the self-service locker 2 abuts against the right-angled extension 132, forming a right-angled notch 23 that mates with the extension 132. (Reference) Figure 1 The depth of the notch 23 of the self-service cabinet 2 allows the inner wall of the notch 23 to fit completely with the outer wall of the extension 132. This "interlocking" fit can effectively prevent the self-service cabinet 2 from moving in the front-to-back direction due to inertia when the train starts or brakes.

[0051] In one embodiment of this disclosure, a vertically extending abutting plate 34 is provided on the rear side of the second end 22. The abutting plate 34 abuts against the first end face 131 and is configured for surface mating. Specifically, refer to... Figure 7 and Figure 8 The second end 22 of the self-service cabinet 2 extends rearward to the first end face 131 of the second limiting structure 13. To further maintain the stability of the self-service cabinet 2, the abutment plate 34 is designed as an "L"-shaped plate with a fixed folding angle. One end face of the abutment plate 34 is fixed to the rear end of the self-service cabinet 2 with screws, and the other end face abuts against the first end face 131 of the second limiting structure 13 through a surface fit. The contact area between the vertically arranged abutment plate 34 and the first end face 131 must ensure that the abutment plate 34 can uniformly transmit the force under vibration environment, avoiding excessive local pressure that could cause deformation of the first end face 131 or the abutment plate 34.

[0052] In one embodiment of this disclosure, reference is made to Figures 1 to 9The first end 21 of the self-service cabinet 2 is parallel to and abuts against the second end face 121 of the first limiting structure 12. When the self-service cabinet 2 is supported on the bar counter 11 and protrudes from the opening end 14, and the front edge of the self-service cabinet 2 is aligned with the edge of the bar counter 11, the parallel and abutting position of the first end 21 of the self-service cabinet 2 and the second end face 121 of the first limiting structure 12 provides a limiting function in the left and right directions. This effectively prevents the self-service cabinet 2 from lateral displacement when the train sways left and right or turns, providing basic lateral limiting support for the self-service cabinet 2. This parallel abutting design maximizes the contact area and evenly distributes the lateral force to the second end face 121 of the first limiting structure 12, preventing damage to the self-service cabinet 2 or the food cart limiting structure due to excessive local force. Meanwhile, when the self-service cabinet 2 is subjected to inertial impact from the left and right sides, the tight contact between the first end 21 and the second end face 121 can directly offset part of the impact force, reduce the shaking of the internal equipment of the self-service cabinet 2, and protect the stable operation of internal vending machines, control modules and other components.

[0053] The first limiting structure 12 also includes a third end face 122 adjacent to the second limiting structure 13, which is adjacent to the second end face 121. The first limiting structure 12 can be a regular quadrilateral column, with the third end face 122 adjacent to and perpendicular to the second end face 121. A first stop mechanism 35 is provided on the rear end face of the self-service cabinet 2, which abuts against the third end face 122 and is constructed as a surface fit. The first stop mechanism 35 on the rear side of the self-service cabinet 2 is a "strip-shaped plate structure," also an "L" shape with a fixed angle in its cross-section. The first stop mechanism 35 is fixed to the rear end face of the self-service cabinet 2 by bolts and fits tightly against the third end face 122. This design can limit the displacement of the self-service cabinet 2 "laterally," forming a "bidirectional limiting" with the limiting structure of the second end 22, ensuring that the self-service cabinet 2 has no room to move on the horizontal plane.

[0054] In one embodiment of this disclosure, reference is made to Figure 5 and Figure 9 The first limiting structure 12 and the second limiting structure 13 are arranged in parallel, and the first end face 131 is perpendicular to the second end face 121; the third end face 122 is parallel to the first end face 131, and an accommodating space 17 is formed between the first end face 131 and the third end face 122. The rear end of the self-service cabinet 2 is constructed to expose the accommodating space 17.

[0055] Specifically, the first limiting structure 12 and the second limiting structure 13 are arranged parallel to each other in space, with a certain distance between them, so that an accommodating space 17 is formed between the first end face 131 and the third end face 122. The vertical height of the accommodating space 17 is the same as the height of the first limiting structure 12 and the second limiting structure 13, and its horizontal width depends on the distance between the first limiting structure 12 and the second limiting structure 13 and the size of the bar counter 11. The pointed area at the rear of the self-service cabinet 2 and the first column 31 are both located within the accommodating space 17, and the utilization rate of the accommodating space 17 is maximized.

[0056] The portion of the rear end of the self-service locker 2 that exposes the accommodating space 17 is not completely empty; rather, it is utilized in a rational manner in conjunction with the functional layout of the self-service locker 2. Since the size of the accommodating space 17 matches the rear structure of the self-service locker 2, the exposed portion can be used to house heat dissipation vents, providing a heat dissipation channel for heat-generating components such as the control unit and vending machine motor inside the self-service locker 2. This prevents heat accumulation due to a closed chamber, which could affect the equipment's lifespan. Furthermore, the exposed area also provides space for maintenance operations. When maintenance is required on the connecting structure of the first column 31 at the rear of the self-service locker 2 or the control unit, staff can quickly perform operations through the exposed accommodating space 17 without significantly moving the self-service locker 2, improving the convenience of maintenance.

[0057] In one embodiment of this disclosure, a space for placing a control unit is formed at the rear end of the self-service cabinet 2 chamber. Specifically, multiple self-service vending machines occupy only the fan-shaped space at the front end of the self-service cabinet 2, leaving the space at the pointed area at the rear end of the self-service cabinet 2 empty, which can be used to place the control unit. The control unit can be configured to have multiple control modules. The space at the rear end of the self-service cabinet 2 where the control unit is placed can also be equipped with an independent cabinet door to prevent maintenance of the control unit from affecting the front-end vending service. In one embodiment of this disclosure, the front ends of three self-service vending machines are arranged inside the self-service cabinet 2, with their rear ends 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 wiring harnesses and control units.

[0058] 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, balancing efficiency, safety, and scalability. The control unit integrates the control of multiple vending machines and multiple functional units, including but not limited to: controlling the startup, hibernation, fault diagnosis, and switching of operating modes of multiple vending machines, 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 can be dynamically adjusted. The control unit supports cross-screen collaboration. After passengers select items on the control screen, they can be assigned to any available vending machine for dispensing, thus optimizing queuing efficiency. The control unit integrates the operation screen, advertising screen (playing public service advertisements or promotional information, etc.), and auxiliary display screens of functional modules (such as payment guidance and product pickup prompts) of the self-service vending machine, enabling synchronized content or 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 self-service cabinet's second chamber (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.

[0059] In one embodiment of this disclosure, the high-speed rail dining car 1 further includes a light strip structure 15 disposed above the bar counter 11, the light strip structure 15 contributing to forming the open end 14. (See reference...) Figure 1 , Figure 2 and Figure 9 The light strip structure 15 is generally arc-shaped, with its inner wall being an arc surface. The arc of the top front side of the self-service cabinet 2 matches that of the light strip structure 15. The arc of the light strip structure 15 matches that of the bar counter 11, and the light strip structure 15, the bar counter 11, the first limiting structure 12, and the second limiting structure 13 together form an open end 14 with a closed shape. The height of the open end 14 is the height from the surface of the bar counter 11 to the bottom of the light strip structure 15, which is named the first height. The front end of the self-service cabinet 2 rests on the bar counter 11 and protrudes from the front end face of the open end 14. The self-service cabinet 2 fits tightly into the open end 14, thus the presence of the light strip structure 15 restricts the height of the self-service cabinet 2, making the height of the front end face, the first end 21, and the second end 22 of the self-service cabinet 2 equal to the first height. Furthermore, the height of the cabinet door located on the rear side of the self-service cabinet 2 is greater than zero and less than the first height.

[0060] A second stop mechanism 36 is installed at the top front of the self-service kiosks 2, and the second stop mechanism 36 abuts against the inner wall of the light strip structure 15. (Reference) Figure 3 and Figure 9 The second stop mechanism 36 is an angle iron structure. One side is fixed to the top front of the self-service cabinet 2 by bolts, and the other side abuts against the inner wall of the light strip structure 15. A cushioning pad can be attached to the abutment. The function of the second stop mechanism 36 is not only to prevent the self-service cabinet 2 from rushing forward out of the opening end 14, but also to calibrate the installation position of the self-service cabinet 2 by cooperating with the light strip structure 15, ensuring that the installation height and front and rear position of all self-service cabinets 2 in the same type of catering cart are consistent, thereby improving overall stability and operational uniformity.

[0061] Multiple second stop mechanisms 36 in different directions can be installed on the top front side of the self-service cabinet 2. For example, 2-3 second stop mechanisms 36 can be installed at intervals along the arc-shaped trajectory of the top front side of the self-service cabinet 2, and they abut against the inner wall of the light strip structure 15 from different angles. This multi-point abutment design can further enhance the limiting stability and prevent the self-service cabinet 2 from tilting forward due to the failure of a single stop mechanism. At the same time, the abutment surface of each second stop mechanism 36 can be finely adjusted according to the curvature difference of the inner wall of the light strip structure 15 to ensure that each stop mechanism can fit tightly against the inner wall of the light strip, forming a uniform force point, which not only prevents the self-service cabinet 2 from moving back and forth, but also avoids local compression damage to the light strip structure 15.

[0062] In one embodiment of this disclosure, reference is made to Figure 4 The self-service cabinet 2 has a third stop mechanism 38 at its bottom, which is configured to abut against the inner wall of the bar counter 11. The third stop mechanism 38 at the bottom of the self-service cabinet 2 is also an angle iron structure, and its installation position is located on the side of the bottom of the self-service cabinet 2 closest to the inner wall of the bar counter 11. One side of the third stop mechanism 38 is fixed to the bottom front of the self-service cabinet 2 with bolts, and the other side abuts against the inner wall of the light strip structure 15, where a cushioning pad can be attached. When the front of the self-service cabinet 2 rests on the bar counter 11, the third stop mechanism 38 can restrict the front-back displacement of the self-service cabinet 2 from below, forming a "bidirectional limit" with the second stop mechanism 36 at the top, further enhancing the front-back stability of the self-service cabinet 2. Similarly, multiple third stop mechanisms 38 in different directions can be installed at the bottom front of the self-service cabinet 2 to abut against the inner wall of the bar counter 11.

[0063] In one embodiment of this disclosure, such as Figure 5 As shown, the bar counter 11 is constructed with a double-layer structure, including a first-layer bar counter 111 and a second-layer bar counter 112 located below the first-layer bar counter 111. The bottom of the front side of the self-service cabinet 2 is supported on the surface of the first-layer bar counter 111, and a second column 32 is provided on the second-layer bar counter 112. The self-service cabinet 2 is supported on the surface of the second-layer bar counter 112 by the second column 32.

[0064] Specifically, in terms of height, the second bar counter 112 is lower than the first bar counter 111. The bottom of the front side of the self-service cabinet 2 is supported by the surface of the first bar counter 111, so that the weight of the front side of the self-service cabinet 2 is distributed on the first bar counter 111. The surface of the first bar counter 111 serves as a stable load-bearing surface, ensuring that the weight of the front side of the self-service cabinet 2 is evenly distributed and avoiding localized stress. The second column 32 is set on the second bar counter 112, supporting the bottom of the self-service cabinet 2, and is located in front of the first column 31. The second column 32 fills the height difference between the surface of the second bar counter 112 and the first bar counter 111. That is, the upper surface of the second column 32 placed on the second bar counter 112 is at the same level as the surface of the first bar counter 111, so that the bottom of the self-service cabinet 2 forms a horizontal contact with the second column 32, thereby allowing the weight of the middle part of the self-service cabinet 2 to be evenly distributed on the second bar counter 112 through the second column 32.

[0065] The second column 32 is an irregularly shaped column that adapts to the shape of the second-level bar counter 112. It transfers the weight of the self-service cabinet 2 to the surface of the second-level bar counter 112, ensuring that the entire weight of the front of the self-service cabinet 2 is supported by the double-layered bar counter 112. The second column 32 allows for on-site fine-tuning to accommodate manufacturing errors, preventing the self-service cabinet 2 from tilting due to unevenness of the bar counter 11. This design enhances the anti-tipping capability of the self-service cabinet 2, making it particularly suitable for the inertial impact of train turns. Thus, the self-service cabinet 2 can utilize the dining car floor 16, the first-level bar counter 111, and the second-level bar counter 112 to provide three levels of gravity support, ensuring its stability even under the vibrations of train operation.

[0066] In one embodiment of this disclosure, the surface of the first-layer bar counter 111 is configured as a concave surface with higher edges and a lower center. A pad 39 is provided between the concave surface and the bottom of the front side of the self-service cabinet 2. Specifically, the shape of the pad 39 is constructed as an arc shape adapted to the first-layer bar counter 111, so that the pad 39 can completely fit and cover the surface of the first-layer bar counter 111, ensuring that the weight of the front side of the self-service cabinet 2 can be evenly distributed on the surface of the first-layer bar counter 111. The pad 39 serves as an intermediate layer between the self-service cabinet 2 and the first-layer bar counter 111, adapting to the shape of the first-layer bar counter 111, providing flat support for the bottom of the self-service cabinet 2. During train operation, to avoid the safety hazard caused by the pad 39 being misaligned due to inertia and resulting in displacement of the self-service cabinet 2, and to maintain the stability of the overall structure, multiple elastic pads are provided between the pad 39 and the surface of the first-layer bar counter 111. The multiple elastic pads are constructed to be distributed sequentially along the extension direction of the first-layer bar counter 111. Multiple elastic pads provide multi-point cushioning and fine-tuning, compensating for concave surface tolerances and increasing the stability of the pad 39. The elastic pads absorb vibration and impact through elastic contact, while evenly transferring the weight from the pad 39 to the surface of the first-layer bar counter 111. The elastic pads can be annular rubber structures, or other elastic materials and shapes, which are not limited in this disclosure. The elastic pads evenly distribute the pressure of the self-service cabinet 2, compensating for the concave depth of the first-layer bar counter 111, effectively preventing localized stress concentration that could lead to cracking of the pad 39. Furthermore, the material of the pad 39 is not specifically limited in this disclosure.

[0067] In one embodiment of this disclosure, the bottom of the bar counter 11 is configured with a cover plate, which is connected to the bottom of the bar counter 11 via mounting holes 113. A storage cabinet is originally provided below the bar counter 11, and a cover plate is provided below the storage cabinet. This cover plate is connected to the bottom of the bar counter 11 by screws; this is a proprietary structure of the high-speed rail dining car 1. Figure 5 and Figure 6 As shown, when the cover plate is connected to the bottom of the bar counter 11, several mounting holes 113 are formed at the bottom of the bar counter 11. A connector 37 is provided at the bottom of the first column 31. The connector 37 is fixedly connected to the bottom of the bar counter 11 through the mounting holes 113 when the cover plate is removed. Since the first column 31 is located at the bottom of the rear side of the self-service cabinet 2, there is a distance between the first column 31 and the bar counter 11. To further improve the overall stability of the self-service machine system and compensate for the distance between the first column 31 and the bar counter 11, a connector 37 is provided between the first column 31 and the inner wall of the bar counter 11. The connector 37 fixes the position of the first column 31, thereby limiting the position of the self-service cabinet 2 fixedly connected to the first column 31. During train operation, it will not shift due to vibration or inertia, and will always maintain a stable state with respect to the existing structure of the dining car.

[0068] like Figure 4 and Figure 9As shown, the connector 37 can adopt an "I"-shaped metal plate structure. One end is fixed to the bottom side wall of the first column 31 by bolts, and the other end is connected to the original mounting hole 113 at the bottom of the bar counter 11 by screws. To accommodate the differences in the spacing of the mounting holes 113 of the bar counter 11 in different high-speed rail dining cars 1, a long strip-shaped adjustment hole can be provided on the connector 37 to facilitate fine-tuning of the connection position during installation, ensuring a firm and precise connection between the first column 31 and the bar counter 11. In addition, an anti-slip rubber pad can be attached to the surface of the connector 37 that contacts the bottom of the bar counter 11. This increases friction and further restricts the horizontal displacement of the first column 31; it also prevents direct contact between the metal connector 37 and the bottom of the bar counter 11, preventing scratches to the original structure of the dining car, achieving non-destructive installation while improving the overall connection stability.

[0069] When fixing the first column 31, the cover plate at the bottom of the bar counter 11 of the high-speed rail dining car 1 can be removed to expose the mounting hole 113 at the bottom of the bar counter 11. The top of the first column 31 is connected to the bottom of the self-service cabinet 2 with screws, thereby initially defining the position of the first column 31 and improving the stability of the self-service cabinet 2. After the self-service cabinet 2 is placed on the first bar counter 111 and the second bar counter 112, and exposed from the opening end 14, and in a position that matches its surrounding structure, the bottom of the first column 31 is connected to the bottom of the bar counter 11 through the connector 37. The connector 37 is engaged with the mounting hole 113 by screws, so that the first column 31 can be more stably supported on the floor 16 of the high-speed rail dining car 1 and will not shift with the vibration of the carriage. The self-service machine system disclosed herein utilizes the original mounting hole 113 of the high-speed rail dining car 1 to fix the first column 31, avoiding the need for drilling on the high-speed rail dining car 1.
