Vibration-attenuation installation structure and method of functional module in insertion box and insertion box

Abstract

The invention relates to a vibration-attenuation installation structure and method of a functional module in an insertion box. The vibration-attenuation installation structure comprises a sliding groove and a guide rail, wherein the sliding groove is formed in the insertion box, the guide rail is arranged on the functional module, the guide rail is matched with the sliding groove in a sliding wayand is inserted into the sliding groove, the functional module is arranged in the insertion box, and the vibration-attenuation installation structure is characterized in that a vibration-attenuation press device is arranged on the sliding groove and moves on the sliding groove to press the guide rail or loosen pressing of the guide rail. The functional module in the insertion box is higher in installation stability, the vibration of each functional module in the insertion box under a vehicle-mounted state can be effectively reduced, the wear of the guide rail and the sliding groove is reduced,the functional module is higher in installation reliability and longer in service lifetime, and equipment is in the insertion box is higher in running safety. The invention also provides the insertion box.

Description

technical field [0001] The invention relates to a vibration-damping installation structure and method of a functional module in a sub-box, which is used to reduce the vibration of the functional module in the sub-box in a vehicle state. The invention also relates to a sub-box. Background technique [0002] Traction drive system is the "heart" unit of rail transit vehicle equipment to realize electromechanical energy conversion. Its performance determines the power quality, energy consumption and control characteristics of rail transit vehicles to a certain extent, and is the key to energy-saving upgrade of rail transit. As the core components of the traction drive system, the converter controller and network controller are integrated in the traction drive controller sub-box. [0003] As the product integration becomes higher and higher, more and more functions are given to the subrack. In addition to commonly used plug-ins, some larger functional module units are often integ...

AI Technical Summary

Problems solved by technology

In this solution, the guide rail is pressed into the bracket by pressing blocks, rubber heat and bolts to reduce the deceleration between the guide rail and the bracket, but the functional modules in the sub-box need to be pulled out of the sub-box quickly and conveniently for The bolts that hold down the guide rails are located on both sides and in the middle of the bracket, making it impossible to fast and conveniently tighten the bolts and pull the functional modules out of the sub-box

[0007] Although the above two patents relate to the anti-loosening and vibration reduction of the guide rail, they do not solve the problems existing in the guide rail mentioned above. Therefore, the installation structure of the functional modules in the existing subrack is improved by reducing the distance between the guide rail and the chute. Vibration, reducing the vibration of functional modules is the research direction of the present invention
