Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical manufacturing, specifically relating to a test bench for the entrance door of the driver's cab of a high-speed railway passenger compartment. Background Technology
[0002] Currently, in the rail transit industry, the design of high-speed railway vehicles not only pursues a streamlined aesthetic on the outside but also places higher demands on the visual effects and ergonomics of the interior. Many components, such as the driver's cab entrance door, employ complex curved surface designs. However, existing supporting experimental and verification equipment often focuses too much on achieving single functions in its design, with less consideration given to simulating real-world loading conditions, reflecting curved surface designs, and integrated testing. In other words, the application of mechanical process equipment technology on the test bench is minimal. This leads to discrepancies between the test bench and the actual loading environment, making it impossible to comprehensively verify the door system's functionality, visual appearance, and assembly process. Utility Model Content

[0004] The frame has a bottom support frame, a longitudinal support extending upward from the bottom support frame, and an upper support frame connected to the top of the longitudinal support frame.
[0005] An interface board is installed on the frame for installing the door leaf and interface board accessories;
[0006] The door leaf is rotatably connected to the mounting interface plate via hinges;
[0007] The longitudinal support includes a support tube that is inclined at a non-perpendicular angle to the bottom support frame, and the mounting interface plate is fixed on the inclined support tube.
[0008] Furthermore, the bottom support frame is constructed by welding two long rectangular tubes and five short rectangular tubes.
[0009] Furthermore, the mounting interface plate has a curved profile notch that penetrates the plate body, the shape of which matches the profile of the local protrusion of the door when it is closed.
[0010] Furthermore, the interface board accessory includes a side-standing integrated plate, and the mounting interface board is provided with mounting holes for mounting the side-standing integrated plate; the side-standing integrated plate is a plate-shaped component that integrates the lock body and the gas pipeline interface, and is also provided with a signal switch that can be triggered by the door leaf.
[0011] Furthermore, the interface board accessory includes a filter pressure reducing valve assembly, and the mounting interface board is provided with mounting holes for mounting the filter pressure reducing valve assembly.
[0012] Furthermore, the rotation axis of the hinge forms a non-90-degree angle with the surface of the mounting interface plate.
[0013] Furthermore, the mounting holes on the mounting interface plate are oblong holes.
[0014] Furthermore, the mounting interface plate is also fixed with a pad for mounting hinges or locks.
[0015] Furthermore, lifting lugs are welded onto the upper support frame.
[0016] Furthermore, the frame is welded from square tubing, and the mounting interface plate is made of sheet metal.
[0017] In summary, the beneficial effects of this utility model are as follows:
[0018] This invention achieves accurate simulation of the actual loading state of the driver's cab entrance door on a high-speed railway by setting up a frame with a specific tilt angle and a matching installation interface plate. It solves the problem that the experimental environment does not match reality due to the simple design of existing experimental benches and their inability to fit the curved surface of the vehicle body.
[0019] This invention achieves modular and integrated testing of multiple components such as door locks, hinges, and signal switches by integrating side-mounted integrated plates, filter pressure reducing valve assemblies, and various electrical and pneumatic connections on the mounting interface plate. This solves the shortcomings of the prior art where experimental equipment is functionally dispersed and cannot be comprehensively verified. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. Example
[0029] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0030] Please see Figures 1 to 5 This utility model provides an experimental bench for the driver's cab entrance door of a high-speed railway passenger compartment, which aims to simulate the actual installation and working environment of the driver's cab entrance door in a high-speed railway vehicle, and to test and verify the function of the door and its related systems.
[0031] The main body of the experimental platform is a welded frame 1. A bottom support frame 13 is provided at the bottom of the frame 1 for stable placement on the ground. In a preferred embodiment, the bottom support frame 13 is welded from two longer square tubes and five shorter square tubes, forming a stable rectangular base. The frame 1 also includes longitudinal supports extending upwards from the bottom support frame 13 and an upper support frame 11 connected to the top of the longitudinal supports. Part of the longitudinal supports are inclined support tubes 12, which connect to the bottom support frame 13 at a non-perpendicular predetermined angle. A mounting interface plate 2, serving as the core mounting base, is firmly fixed to the inclined support tube 12, thus placing the mounting interface plate 2 in an inclined state as well. This inclined design simulates the actual inclination of a high-speed train body panel. Lifting lugs are welded to the upper support frame 11 to facilitate the hoisting and transfer of the platform. The entire frame 1 can be welded from 60×60×3mm square tubing using gas shielded welding, while the mounting interface plate 2 can be made from 10mm thick Q235-A ordinary carbon steel sheet using laser cutting, ensuring the strength of the structure and the precision of the processing.
[0032] The door panel is the main test object of the experimental bench, and it is rotatably mounted on the mounting interface plate 2 via hinge 7. Because the door panel itself has a curved shape, when closed, there is a localized inward protrusion towards the mounting interface plate. To ensure the door panel can be fully closed and tightly fitted to the mounting interface plate, the mounting interface plate 2 has a curved notch that penetrates the plate. The contour of this notch matches the shape of the protrusion when the door panel is closed, providing clearance for the protrusion.
[0033] The mounting interface plate 2 is an integrated platform for multiple components, used to install the door leaf and various interface plate accessories. In this embodiment, the interface plate accessories include a side-mounted integrated plate 8 and a filter pressure reducing valve assembly 6. The mounting interface plate 2 has pre-drilled mounting holes for these accessories. The side-mounted integrated plate 8 itself integrates the door lock body, gas pipeline interface, and a signal switch that can be triggered by the door leaf, used to test the door lock function and the accuracy of the switch signal. The filter pressure reducing valve assembly 6 is used to connect to an external air source and regulate the air pressure, providing a suitable power source for the pneumatic accessories of the door leaf, such as the pneumatic lock.
[0034] To further optimize assembly accuracy and strengthen the connection of key components, pads can be added to the mounting interface plate 2 at the positions corresponding to hinges 7, locks, and other accessories. These pads include hinge pad 14, main lock pad 15, upper auxiliary lock pad 16, lower auxiliary lock pad 17, and stop pad 18. These pads can be used as independent parts and fixed to the mounting interface plate 2 by welding or bolting.
[0035] The key technical point of this invention lies in the fact that, since the mounting interface plate 2 is inclined, and the door leaf needs to open and close on a horizontal plane to conform to ergonomics and practical usage habits, the rotation axis of the hinge 7 and the surface of the mounting interface plate 2 are designed to form a non-90-degree angle when the door leaf is connected to the mounting interface plate 2 via the hinge 7. By precisely calculating and setting this angle, the inclination of the mounting interface plate 2 can be compensated, ensuring that the trajectory plane swept by the door leaf during opening and closing remains parallel to the horizontal plane where the bottom of the frame is located.
[0036] Considering the potential accumulation of tolerances during manufacturing and assembly, some mounting holes on the mounting interface plate 2 are designed as oblong holes to facilitate debugging and precise alignment. During assembly, the adjustment margin provided by the oblong holes can be used to fine-tune the positions of components such as door panels and locks, ensuring ideal assembly relationships and fit clearances between components, thereby accurately simulating and verifying the assembly quality characteristics of the product.
[0037] In summary, this utility model, through its integrated framework design and modular component integration, constructs an experimental platform capable of highly simulating real-world vehicle loading conditions. It can not only verify basic functions such as door opening and closing and locking, but also conduct reliability tests such as pressure resistance and impact vibration, providing strong support for the research, development, inspection, and quality control of high-speed railway passenger compartment and driver's cab entrance doors.
[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
