Description

Technical Field

[0001] The present invention relates to the field of rail vehicle interior system design, and in particular to a side top plate locking structure that prevents falling off and loosening, and an installation method thereof. Background Art

[0002] The side roof panels are located on both sides of the top of the vehicle, and are usually equipped with dynamic maps, speakers and other equipment inside. Therefore, the side roof panels must have the characteristic of flexible opening to facilitate equipment maintenance. The currently commonly used side roof panel locking structure includes a compression lock, a rubber block and a lock bracket. The rubber block is bonded and fixed to the side roof panel. Due to the height error of the compression lock and the installation error of each component, it is usually necessary to bond rubber skins of different thicknesses to the rubber block to adjust the gap between the side roof panel, the compression lock and the lock bracket. As the vehicle runs for a longer time, this locking structure will experience the phenomenon of rubber skins and rubber blocks falling off and the compression lock loosening, which will cause abnormal noises from the side roof panel or even malfunctions such as being pulled open by passengers, posing a safety risk.

[0003] Specifically, the current rail vehicle side roof locking structure includes a rubber block, a rubber skin, a flat lock tongue compression lock, and a lock bracket. The rubber block is bonded to the side roof, and the spacing between the rubber block, the lock bracket, and the lock tongue is adjusted by bonding rubber skins of different thicknesses. The method of bonding rubber blocks and rubber skins to achieve a compression lock has the following defects: 1. The bonding is greatly affected by the environment and is not suitable for high temperature, humid and hot areas, and has regional restrictions; 2. Standard bonding has certain requirements for the construction process, environment, and temperature. The process is cumbersome and the waiting time is long; 3. The rubber skin is prone to falling off during later operation, which can cause the compression lock to loosen and the side roof panel to make abnormal noises; 4. The flat head lock tongue has no limit. When the side roof panel is deformed or the compression lock is loose, it is easy for passengers to pull open the side roof panel, causing a safety malfunction. Therefore, there is an urgent need for an adjustable side roof locking structure that prevents detachment and loosening while avoiding the use of bonding.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention
