Description

Technical Field

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

[0002] In high-speed rail operations, the installation of self-service machines in dining cars requires consideration of various factors: it must not obstruct the normal passage of passengers and train staff, while also making full use of the existing structure of the dining car; moreover, the vibration environment generated by high-speed rail operation places high demands on the stability of the self-service machines, requiring a stable support structure; furthermore, since high-speed rail regulations strictly prohibit drilling or welding on the original structure of the dining car, the support structure of the self-service machines must also be reversibly disassembled without damaging the existing structure of the dining car. Currently, there is an urgent need to overcome key technical bottlenecks such as structural optimization of the support components of high-speed rail dining car self-service machines and non-destructive fixing mechanisms. Utility Model Content

[0003] This disclosure provides a self-service machine for high-speed rail dining cars to address the problems existing in the prior art.

[0004] According to a first aspect of this disclosure, a self-service machine for a high-speed rail dining car is provided. The high-speed rail dining car includes a floor and a double-layer bar supported on the floor. The double-layer bar includes a first bar and a second bar lower than the first bar; comprising: The cabinet contains a vending machine. The front side of the cabinet is configured to fit the shape of the first bar counter, and the bottom of the front side of the cabinet is configured to support the surface of the first bar counter. A first support member is configured to be disposed at the bottom of the rear side of the housing and is configured to extend from the bottom of the housing to be supported on the floor. The second support member is configured to be disposed at the bottom of the box and located in front of the first support member, and the box is configured to be supported on the surface of the second bar by the second support member; The vending machine is configured within the box to extend at least from a position corresponding to the first bar to a position corresponding to the second bar.

[0005] In one embodiment of this disclosure, the first bar counter is arc-shaped, and the front end of the cabinet is configured to be arc-shaped to match the shape of the first bar counter.

[0006] In one embodiment of this disclosure, the high-speed rail dining car further includes an arc-shaped light strip disposed above the first bar, and the top of the front side of the box is configured to extend forward to the light strip.

[0007] In one embodiment of this disclosure, the surface of the first bar counter is configured as a concave surface with high edges and low center, and a pad is provided between the concave surface and the bottom of the front side of the cabinet.

[0008] In one embodiment of this disclosure, a plurality of elastic pads are provided between the pad and the surface of the first bar counter, and the plurality of elastic pads are configured to be distributed sequentially along the extension direction of the first bar counter.

[0009] In one embodiment of this disclosure, the second support abuts against the surface of the second bar counter and is configured to fit the shape of the second bar counter.

[0010] In one embodiment of this disclosure, the high-speed rail dining car includes a cover plate located at the bottom of a double-layer bar counter, the cover plate being configured to connect to the bottom of the double-layer bar counter via mounting holes; The first support member is connected to the box body by screws, and a connector is provided at the bottom of the first support member. The connector is configured to be fixedly connected to the bottom of the double-layer bar counter through the mounting hole.

[0011] In one embodiment of this disclosure, an extension is provided between the connector and the first support. The extension has two support arms, which are configured to extend from the first support towards the connector, and the two ends of the two support arms are fixedly connected to the first support and the connector, respectively.

[0012] In one embodiment of this disclosure, multiple vending machines are provided, and the multiple vending machines are arranged radially in the direction from the rear end to the front end of the housing, and the gap between the rear ends of two adjacent vending machines is smaller than the gap between their front ends.

[0013] In one embodiment of this disclosure, the rear end of the housing forms a pointed region, and the first support is configured to connect to the pointed region.

[0014] One beneficial effect of this disclosure is that the self-service machine utilizes the food cart floor, a first-level bar counter, and a second-level bar counter for gravity support. The machine's casing is supported by a first bar counter, a first support member, and a second support member. The bottom of the front side of the casing is supported by the surface of the first bar counter. The first support member is placed on the food cart floor and located at the bottom of the rear side of the casing. For the structure where the second bar counter of the double-layered bar counter is lower than the first bar counter, the second support member is located at the bottom of the casing and in front of the first support member, with the casing supported by the second support member on the surface of the second bar counter. The front side of the casing is constructed to fit the shape of the first bar counter, allowing it to fit snugly against the bar counter's contours and avoiding loosening or safety hazards caused by installation gaps. A vending machine is installed inside the casing, extending from a position corresponding to the first bar counter to at least a position corresponding to the second bar counter. This fully utilizes the vertical space of the double-layered bar counter and distributes the weight of the front side of the casing across the first and second bar counters, while the load of the rear side is distributed on the floor, creating a balance of forces. The self-service machine solves its own stability problem through this adaptive support structure, which significantly reduces the risk of failure caused by shaking during high-speed rail operation.

[0026] This disclosure provides a self-service machine for a high-speed rail dining car. The high-speed rail dining car includes a floor and a double-layer bar counter. The double-layer bar counter includes a first bar counter and a second bar counter lower than the first bar counter. The self-service machine includes a housing, a first support member, and a second support member. The housing of the self-service machine is supported by the first bar counter, the first support member, and the second support member, and a self-service vending machine is installed inside the housing. The self-service vending machine extends from a position corresponding to the first bar counter to a position corresponding to the second bar counter within the housing. The front side of the housing is constructed to fit the shape of the first bar counter, and its front bottom is supported on the surface of the first bar counter. The first support member is located at the bottom of the rear side of the housing and extends from the bottom of the housing to be supported on the floor. The second support member is located at the bottom of the housing and in front of the first support member. The housing is supported on the surface of the second bar counter by the second support member, so that the weight of the front side of the housing is distributed on the first and second bar counters, and the load of the rear side is distributed on the floor through the first support member, forming a front-to-back force balance. One beneficial effect of this disclosure is that, for a double-layer bar counter structure, the existing structure of the food cart is used as a supporting structure to solve the problem of stable fixation of the self-service machine.

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

[0028] like Figure 1 , Figure 2 As shown, this disclosure provides a self-service machine for a high-speed rail dining car, including a housing 10, a first support member 12, and a second support member 13. Figure 3 and Figure 4 As shown, the high-speed rail dining car includes a floor 2 and a double-layer bar counter 3. The double-layer bar counter 3 is supported on the floor 2 of the dining car. The double-layer bar counter 3 includes a first bar counter 31 and a second bar counter 32, wherein the second bar counter 32 is lower than the first bar counter 31 in the height direction.

[0029] A vending machine 11 is installed inside the cabinet 10 of the self-service machine. The front side of the cabinet 10 is constructed to fit the shape of the first bar counter 31, and the bottom of the front side of the cabinet 10 is constructed to support the surface of the first bar counter 31, so that the weight of the front side of the cabinet 10 is distributed on the first bar counter 31. The surface of the first bar counter 31 serves as a stable load-bearing surface, ensuring that the weight of the front of the cabinet 10 is evenly distributed and avoiding localized stress.

[0030] like Figure 1 and Figure 5As shown, the first support member 12 is configured to be located at the bottom of the rear side of the container 10, and is configured to extend from the bottom of the container 10 to support the floor 2. Through the first support member 12, the weight of the rear side of the container 10 can be distributed on the floor 2 of the carriage, preventing the container 10 from swaying or tipping over. This weight-distribution design effectively utilizes the limited space of the dining car, improves overall stability, and reduces the impact of vibration during train operation. Specifically, the frame of the container 10 can be made of lightweight aluminum alloy or other materials, which are not limited herein. Such material selection ensures support strength while reducing weight, facilitating installation and maintenance in the confined environment of the dining car. Figure 2 As shown, the bottom of the first support member 12 can be constructed as an irregular quadrilateral to accommodate spaces other than the double-layer bar counter 3. The material of the first support member 12 can also be lightweight aluminum alloy or other materials, and this disclosure does not impose any limitations. The rear side of the first support member 12 is constructed to have a door that can be opened and closed, facilitating adjustment and maintenance during use.

[0031] Continue to refer to Figure 2 The second support member 13 is configured to be positioned at the bottom of the cabinet 10 and in front of the first support member 12. The cabinet 10 is supported on the surface of the second bar counter 32 by the second support member 13. The second bar counter 32 is lower than the first bar counter 31, and there is a height tolerance between the surfaces of the second bar counter 32 and the first bar counter 31. The height of the second support member 13 fills this height tolerance. The upper surface of the second support member 13, placed on the second bar counter 32, is at the same level as the surface of the first bar counter 31, so that the bottom of the cabinet 10 and the second bar counter 32 form a horizontal contact, thereby evenly distributing the weight of the middle part of the cabinet 10 onto the second bar counter 32 through the second support member 13. The second support member allows for on-site fine-tuning to accommodate manufacturing errors and prevents the cabinet 10 from tilting due to unevenness of the bar counter. This design enhances the anti-tipping capability of the self-service machine, and is especially suitable for the inertial impact when a train turns. Thus, the self-service machine can be supported by three levels of gravity using the dining car floor 2, the first bar counter 31, and the second bar counter 32, so that the self-service machine can remain stable under the vibration of the train in motion.

[0032] The vending machine 11 is constructed within the housing 10, extending at least from the position corresponding to the first bar counter 31 to the position corresponding to the second bar counter 32. Specifically, the housing 10 for the vending machine is installed using the vertical space between the first bar counter 31 and the second bar counter 32. The weight of the vending machine 11 within the housing 10 is primarily distributed across the first bar counter 31 and the second bar counter 32 via the bottom of the housing 10, thereby increasing the stability of the housing 10. The extended length of the vending machine 11 corresponds to the support position of the double-layer bar counter 3 on the housing 10, and the weight is directly transferred to the first bar counter 31 and the second bar counter 32 via the bottom of the housing 10, reducing reliance on the floor 2 for support and improving the stability of the housing 10.

[0033] In one embodiment of this disclosure, the first bar counter 31 is arc-shaped, and the front end of the cabinet 10 is configured to be arc-shaped to match the shape of the first bar counter 31. Figures 3 to 6 As shown, the upper surface of the first bar counter 31 is an arc-shaped plane, and the arc structure at the front end of the cabinet 10 matches the arc of the first bar counter 31 to form a continuous contact surface, ensuring that the weight of the front part of the cabinet 10 is evenly distributed on the surface of the first bar counter 31; and the lower edge of the front side of the cabinet 10 coincides with the front edge of the first bar counter 31.

[0034] In one embodiment of this disclosure, the high-speed rail dining car also includes an arc-shaped light strip 4 disposed above the first bar counter 31, and the top of the front side of the car body 10 is configured to extend forward to the light strip 4. Specifically, as Figures 3 to 6 As shown, the arc structure at the top of the cabinet 10 matches the curvature of the light strip 4, and the top of the cabinet 10 extends to the outer edge of the light strip 4. Two angle iron components are installed at the point where the top of the cabinet 10 meets the inner edge of the light strip 4. One side of the angle iron is connected to the top of the cabinet 10 with screws, and the other side abuts against the inner edge of the light strip 4. This abutting relationship prevents the cabinet 10 from shifting forward. The curvature of the light strip 4 matches the curvature of the first bar counter 31. Furthermore, the upper and lower edges of the front side of the cabinet 10 have the same curvature, allowing for a tight fit with both the light strip 4 and the first bar counter 31.

[0035] In one embodiment of this disclosure, such as Figure 8 As shown, the surface of the first bar counter 31 is configured as a concave surface 311 with higher edges and a lower center, and a pad 14 is provided between the concave surface 311 and the bottom of the front side of the cabinet 10. Specifically, as shown... Figure 2 As shown, the pad 14 is an arc shape adapted to the first bar counter 31, allowing it to completely fit and cover the surface of the first bar counter 31, ensuring that the weight of the front of the cabinet 10 is evenly distributed on the bar counter surface. The pad 14 serves as an intermediate layer between the cabinet 10 and the first bar counter 31, adapting to the shape of the first bar counter 31 to provide flat support for the bottom of the cabinet 10. During train operation, it prevents the cabinet 10 from shifting due to inertia caused by misalignment of the pad 14, thus maintaining the stability of the overall structure. Furthermore, the material of the pad 14 is not specifically limited in this disclosure.

[0036] In one embodiment of this disclosure, a plurality of elastic pads are disposed between the surface of the pad 14 and the surface of the first bar counter 31. These elastic pads are configured to be distributed sequentially along the extending direction of the first bar counter 31. Specifically, the surface of the first bar counter 31 is a concave surface 311 with higher edges and a lower center. The elastic pads are disposed between the pad 14 and the concave surface 311, and are distributed sequentially along the extending direction of the first bar counter 31. This provides multi-point buffering and fine-tuning, compensates for the tolerances of the concave surface 311, and increases the stability of the pad 14. The elastic pads absorb vibration and impact through elastic contact, while uniformly transferring the weight from the pad 14 to the surface of the first bar counter 31. The elastic pads can be annular rubber structures, or other elastic materials and shapes; this disclosure does not limit the types of elastic pads. The elastic pads uniformly distribute the pressure of the cabinet 10, compensate for the depth of the concave surface 311 of the first bar counter 31, and effectively prevent local stress concentration from causing the pad 14 to crack.

[0037] In one embodiment of this disclosure, the second support 13 abuts against the surface of the second bar counter 32 and is configured to adapt to the shape of the second bar counter 32. Specifically, as Figure 3 and Figure 4 As shown, the second bar counter 32 has the same shape as the first bar counter 31, approximately arc-shaped. The surface of the second bar counter 32 is horizontal, the bottom plane of the second support member 13 abuts against the surface of the second bar counter 32, and the top of the second support member 13 is a horizontal contact surface for abutting against the bottom of the cabinet 10. Figure 2 As shown, the second support member 13 is L-shaped, and its bending angle is adapted to the approximately arc-shaped plane of the second bar counter 32. The height of the second support member 13 can compensate for the height difference between the first bar counter 31 and the second bar counter 32, ensuring the horizontal stability of the cabinet 10. The material of the second support member 13 can be plastic, aluminum alloy, or wood, etc., and this disclosure does not impose any restrictions, so that the second support member 13 can improve the self-service machine's anti-tipping resistance and durability in the dynamic environment of a train. The second support member 13 fully abuts against the approximately arc-shaped surface of the second bar counter 32, ensuring maximum contact area while adapting its shape, and distributing the weight of the cabinet 10 evenly on the second bar counter 32 to the greatest extent. Moreover, the second bar counter 32 and the first bar counter 31 have the same curvature, ensuring that the supporting force is evenly transmitted radially, reducing the influence of torsional moment, and making the weight distribution in the middle of the cabinet 10 more balanced.

[0038] In one embodiment of this disclosure, the high-speed rail dining car includes a cover plate located at the bottom of a double-layer bar counter 3. The cover plate is configured to be connected to the bottom of the double-layer bar counter 3 via mounting holes 33. A first support member 12 is connected to the housing 10 by screws, and a connector 16 is provided at the bottom of the first support member 12. The connector 16 is configured to be fixedly connected to the bottom of the double-layer bar counter 3 via mounting holes 33. Below the double-layer bar counter 3 is a storage cabinet, and below the storage cabinet is a cover plate, which is connected to the bottom of the double-layer bar counter 3 by screws. This is the proprietary structure of the high-speed rail dining car. Figure 4 and Figure 9 As shown, when fixing the first support member 12, the cover plate at the bottom of the double-layer bar counter 3 in the high-speed rail dining car can be removed, exposing the mounting holes 33 located at the bottom of the double-layer bar counter 3. The top of the first support member 12 is connected to the bottom of the cabinet 10 with screws, thereby fixing the first support member 12 and improving the stability of the cabinet 10. Figure 5 As shown, after the self-service machine is installed in a position that cooperates with the first bar counter 31, the second bar counter 32, and other surrounding structures, the bottom of the first support member 12 is connected to the bottom of the double-layer bar counter 3 via a connector 16. The connector 16 engages with the mounting hole 33 via screws, allowing the first support member 12 to be more stably supported on the high-speed rail dining car floor 2 and preventing displacement due to vibration of the carriage. The self-service machine disclosed herein utilizes the existing mounting holes 33 of the high-speed rail dining car to fix the first support member 12, avoiding the need for drilling operations on the high-speed rail dining car.

[0039] In one embodiment of this disclosure, an extension 17 is provided between the connector 16 and the first support 12. The extension 17 has two support arms 170, which are configured to extend from the first support 12 toward the connector 16, and both ends of the two support arms 170 are fixedly connected to the first support 12 and the connector 16, respectively. Specifically, since the first support 12 is supported at the rear end of the cabinet 10, there is a certain distance between the first support 12 and the double-layer bar counter 3 in front of it. This distance can be compensated by the extension 17. Figure 7 As shown, the two support arms 170 are designated as the first support arm 171 and the second support arm 172. When installing the first support member 12, the connector 16 is first installed onto the mounting holes at the bottom of the double-layer bar counter 3 using screws. The first support arm 171 and the second support arm 172 are then fastened to both sides of the connector 16 using screws. After the self-service machine is installed in the preset position, the first support arm 171 and the second support arm 172 are connected to the bottom of the rear wall of the first support member 12 using screws, thereby connecting the bottom of the first support member 12 to the double-layer bar counter 3 via the connector 16, increasing the stability of the self-service machine.

[0040] In one embodiment of this disclosure, multiple vending machines 11 are provided. From the rear end to the front end of the housing 10, the vending machines 11 are arranged radially, with the gap between the rear ends of adjacent vending machines 11 being smaller than the gap between their front ends. Specifically, because the front end of the housing 10 has an arc-shaped structure and its size is larger than its rear end, the vending machines 11 can be arranged radially within the housing 10, resulting in a narrow rear end gap and a wide front end gap. This allows the weight of the housing 10 to be distributed radially, with the weight of the vending machines 11 evenly distributed across the bottom of the housing 10 to the first bar counter 31 and the second bar counter 32. This layout utilizes the vertical space of the double-layer bar counter 3 and optimizes the space utilization of the housing 10. It is compatible with the arc structure of the double-layer bar counter 3, further enhancing the stability of the housing 10 and facilitating the transfer of the weight of the housing 10 to the first bar counter 31, the second bar counter 32, and the floor 2. The vending machine 11 has a radial layout, extending its operating interface to the front of the cabinet 10, making it convenient for passengers to purchase and take items.

[0041] In one embodiment of this disclosure, the rear end of the housing 10 forms a pointed region, and the first support member 12 is configured to connect to the pointed region. Specifically, as Figure 5 and Figure 6 As shown, the front end of the cabinet 10 is an arc shape adapted to the double-layer bar counter 3 and the light strip 4. The rear end of the cabinet 10 needs to adapt to other structures besides the double-layer bar counter 3, thus forming a pointed area. Therefore, the cabinet 10 presents an irregular fan shape. The rear side of the cabinet 10 is equipped with a door that can be opened and closed. In the space outside the double-layer bar counter 3, the irregular fan-shaped structure ensures that the opening and closing of the door is not affected, facilitating daily maintenance of the vending machine 11 inside the cabinet 10. The pointed area serves as the concentration point of the weight at the rear of the cabinet 10. Its connection with the first support member 12 ensures that the weight at the rear of the cabinet 10 is distributed on the dining car floor 2, increasing the stability of the cabinet 10. The irregular fan-shaped design adapts to the height of the environmental structure, allowing the vending machine to seamlessly connect with the double-layer bar counter 3 and other surrounding structures, preventing the vending machine from losing balance when the train vibrates and maintaining the overall weight distribution of the vending machine.
