Description

Technical Field

[0001] This utility model relates to rail vehicle door systems, and more particularly to an isolating switch assembly for rail vehicle door systems. Background Technology

[0002] The door system isolation function is extremely important for rail transit vehicles, as it directly affects the vehicle's operational safety. The isolation device is a crucial component of the door system's unlocking structure. When the door system malfunctions, operating the isolation device isolates the door, preventing passengers from opening it themselves and ensuring their safety. Isolating the malfunctioning door does not affect the operation of the entire train. Simultaneously, the isolation device transmits the position of the isolated door to the vehicle control system in real time, allowing vehicle controllers to promptly obtain information and determine whether the door has been properly isolated or if an erroneous operation has occurred. Therefore, the isolating switch assembly is vital for the operational safety of rail transit vehicles.

[0003] The existing disconnect switch assembly has the following shortcomings: (1) The structure is simple and cannot be applied to more complex vehicle body space structures; (2) The disconnect lock box and cam are made by casting, which has high manufacturing cost; (3) The disconnect lock box is made by casting, which requires repeated mold opening to meet the requirements of symmetrical structure, resulting in long manufacturing cycle and high manufacturing cost.

[0004] Therefore, it is necessary to develop new types of disconnector switch components to overcome the above problems. Utility Model Content

[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides an isolating switch assembly for a rail vehicle door system, which can adapt to more complex vehicle body space construction, reduce manufacturing cycle, and effectively reduce manufacturing costs.

[0006] Technical solution: The present invention relates to an isolating switch assembly for a rail vehicle door system, characterized in that it includes a trigger switch, an isolating lock box cover, an aluminum profile extruded cam, a mounting bracket, an isolating lock box base, and an aluminum profile extruded isolating lock box; the trigger switch and the cam form a triggering mechanism, and the mounting bracket and the isolating lock box form a frame mechanism; the isolating lock box has threaded mounting holes on both the upper and lower sides, and the isolating lock box can be flipped into a symmetrical structure.

[0007] The trigger switch is located below the cover of the isolation lock box.

[0008] The isolation lock box base is provided with a cam, a mounting bracket and an isolation lock box.

[0009] The outer contour of the isolation lock box is provided with a concave corner space structure for avoiding the vehicle body.

[0010] The isolation lock box base is located in the rail vehicle door system.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention uses profile extrusion to manufacture the isolation lock box and cam, ensuring structural strength, reducing structural weight, shortening the production cycle, and reducing production costs; the isolation lock box is provided with threaded mounting holes on both the upper and lower sides, and can be flipped and used as a symmetrical structure, eliminating the need for repeated mold making, shortening the production cycle, and reducing production costs; the screw holes on the outer surface of the isolation lock box are provided with concave corner spaces to avoid the vehicle body, so that the isolation switch assembly can adapt to more complex vehicle body space structures.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] This utility model discloses an isolating switch assembly for a rail vehicle door system, comprising a trigger switch 1, an isolating lock box cover 2, an aluminum profile extruded cam 3, a mounting bracket 4, an isolating lock box base 5, and an aluminum profile extruded isolating lock box 6. The trigger switch 1 and cam 3 form a triggering mechanism, and the mounting bracket 4 and isolating lock box 6 form a frame mechanism. The isolating lock box 6 has threaded mounting holes on both its upper and lower sides, and can be flipped into a symmetrical structure. The trigger switch 1 is located below the isolating lock box cover 2. The cam 3, mounting bracket 4, and isolating lock box 6 are located above the isolating lock box base 5. The isolating lock box 6 has a concave corner space structure for avoiding the vehicle body. The isolating lock box base 5 is located within the rail vehicle door system.

[0019] The cam 3 and the isolating lock box 6 of this invention are made of extruded aluminum profiles, reducing the production cycle, lowering production costs, ensuring structural strength, and reducing weight. The isolating lock box 6 has threaded mounting holes on both the upper and lower sides. When the door system requires a symmetrical structure, the isolating lock box 6 can be flipped over and used directly as a symmetrical structure, eliminating the need for repeated profile mold making and reducing costs. The outer contour of the isolating lock box 6 includes concave corner spaces to avoid the vehicle body, allowing the isolating switch assembly to adapt to more complex vehicle space structures. This invention effectively solves the problems existing in current isolating switch assemblies, significantly reducing the production cycle, lowering production costs, and adapting to narrower and more complex vehicle space structures.
