Stainless steel seats are mainly composed of three major components: stainless steel seat seats, aluminum alloy frames, and end plates. The seat seats and frames are connected by bonding, which realizes the connection of dissimilar base materials of aluminum alloy and stainless steel, while improving vibration reduction performance.

[0003] When installing the support plates, the existing flexible bonding device for urban rail passenger compartment seats inserts the supporting cards into the corresponding slots one by one and limits them by connecting the cards. However, when manually fastening the existing flexible bonding device for urban rail passenger compartment seats through the supporting cards and the connecting cards, the staff's power control, fastening techniques and fastening sequence may affect the locking force. The strength differences and fastening habits of different operators may cause deviations in the locking force. Therefore, it may not be possible to ensure that the same locking force is achieved every time, which will affect the stability and accuracy of the seat during the bonding process. In addition, manual fastening has the risk of accidental falling off or safety accidents due to loose or insecure locking.
