Problems solved by technology

[0004] The sliding doors of public transport vehicles in the prior art mainly maintain the locking between the two door panels through threaded self-locking. This kind of sliding door only has a first-level locking function. When the public transport vehicle is running, once the threaded self-locking fails, The door will open, and the safety of passengers in a high-speed public transport vehicle cannot be guaranteed, and there are certain safety hazards

Embodiment 1

[0040] refer to figure 1 , is a secondary locking device for a door of an urban public transport vehicle disclosed by the present invention, comprising a fixed pin 11 connected to the door panel 12 and sliding synchronously with the door panel 12, referring to figure 2, in this embodiment, the fixed pin 11 is fixed on one of the nut pairs 14. When working, the screw motor 13 drives the left and right screw rods to rotate, and the left and right screw drives the nut pairs 14 to slide on the door mechanism 1, thereby driving The door panel 12 slides on the door mechanism 1, and since the fixing pin 11 is connected with the nut pair 14, the fixing pin 11 and the door panel 12 will slide synchronously. In order to stably realize the sliding of the fixed pin 11, a slide rail 15 is provided on the door mechanism 1 along the sliding direction of the door panel 12, and a slide block 151 is connected to slide on the slide rail 15, and the fixed pin 11 is fixed on the slide block 151. ...

Embodiment 2

[0056]A secondary locking device for an urban public transport vehicle door, which is different from Embodiment 1 in that, refer to Figure 7 as well as Figure 8 , in this embodiment, the transmission member includes a transmission rod 9 arranged at the end of the connecting rod 4 away from the lock head 41, the transmission rod 9 is arranged parallel to the rotating shaft of the connecting rod 4, and a fixed sleeve 91 is provided on the bottom plate 2 toward the transmission rod 9, The length direction of the fixed sleeve 91 is tangent to the swing direction of the transmission rod 9, and the end of the stay cord 7 away from the manual operation knob 71 passes through the fixed sleeve 91 and is fixed with the transmission rod 9. After turning the manual operation knob 71, the pull cord 7 will pull the transmission rod 9, thereby driving the connecting rod 4 to rotate, and realizing the manual unlocking of the connecting rod 4.

Abstract

The invention relates to a secondary locking device for an urban public transport vehicle door. The device comprises a fixed pin sliding synchronous with a door plate, and further comprises a bottom plate fixed to a door mechanism, a rotating plate is rotatably connected to the bottom plate, an opening groove allowing the fixed pin to slide in during door closing is arranged on the rotating plate,the rotating plate has a first state waiting for sliding in of the fixed pin, and a second state, according to the state, after the fixed pin slides in, the rotating plate is driven by the fixed pinto rotate to enable the fixed pin to be fixed in the opening groove, a locking part driving the rotating plate to be kept in the second state is arranged on the bottom plate, the bottom plate is provided with a reset elastic part for driving the rotating plate to reset after the locking part is unlocked, through cooperation of the rotating plate and the locking part, when the vehicle door is in the closed state, the fixed pin is fixed to the door mechanism, and therefore the door plate is subjected to secondary locking. When a left-handed screw, a right-handed screw and a nut pair are damaged,the fixed pin can still fix the door plate, the vehicle door is still in the closed state, and life safety of passengers in a vehicle can be ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to a secondary locking device for a vehicle door of an urban public transport vehicle. Background technique [0002] With the rapid advancement of urbanization, urban public transportation is becoming more and more developed. Urban public transportation vehicles refer to buses (electricity), taxis, subways, passenger ferries, cable cars, cableways and other cities that serve the production and life of urban residents. public transport vehicles. [0003] Existing sliding doors of urban public transport vehicles mainly include two types, one is common sliding doors, and the two door panels only slide relative to each other to realize the opening and closing of the vehicle door. There is a nut pair matched with the left and right screw rods on the top, and the two door panels are approached and separated from each other by turning the left and right screw rods; the other t...
