Description

Multi-contact remote electromagnetic reset passenger emergency brake with spring pin lock position Technical Field The invention relates to the technical field of emergency braking units of rail transit buses, in particular to an integrated spring pin locking multi-contact remote electromagnetic resetting passenger emergency braking brake. Background The high-speed rail motor train unit and part of subway vehicles which are put into use at present are provided with emergency brake pull-down of passengers, the emergency brake pull-down can be pulled down by passengers or crews under emergency conditions, warning signals are sent to a driver by the emergency brake pull-down, whether the train is parked or not is processed by the driver according to road conditions and vehicle conditions within 3 seconds, and if the train is not processed after 3 seconds, the train is braked automatically. So that the whole train can be stopped quickly and safely. In the normal running process of the train, some emergency situations in the passenger room occasionally occur and the train needs to stop, but in many cases, a driver cannot know the emergency situations, so the emergency situations of passengers cannot be treated in time, and then the passengers suffer from infinity. Most of the defects of the existing emergency brake are that a decorative box or a cover is required to be additionally arranged, three types of existing emergency brake pull box cover assembly are adopted, one type of existing emergency brake pull box cover assembly is that only the decorative box is used, no cover is arranged, one type of emergency brake pull box adopts an elastic cover structure, one type of emergency brake pull box adopts a decorative box and cover capable of breaking the cover, and part of vehicles adopt split tortoise back cover type emergency brake pull. The existing emergency brake release has the defect that only the decorative box is not covered, so that the emergency brake release is easy to be operated by passengers by mistake due to the fact that the release is exposed, the train stops without accident, and the operation safety of the train is affected. When the elastic cover body is operated, the upper end of the elastic cover body is pulled out after the upper slide rail is pulled out, the elastic cover body is taken down after the lower slide rail is pushed out, the emergency brake is operated, the operation steps are very complicated, and passengers can cause delay time to influence the timeliness of operating the emergency brake and influence the operation safety of a train. The cover is formed by a decorative box and a cover which can be broken, and the cover can only be used once, so that the cover is extremely easy to be broken due to mistaken collision or vibration impact during long-time operation. When the emergency brake is installed with a vehicle, a chute is needed to be added on a vehicle wallboard, the handle assembly is detached from the handle seat, the base of the emergency brake is connected with the support through the fastening piece, the support is installed on the chute on the vehicle wallboard through the fastening piece, the handle assembly is installed back through the fastening piece, the installation space of the fastening piece is extremely narrow, and the operation is difficult. The decorative box is then mounted to the bracket with fasteners, and the cover is then mounted to the decorative box with fasteners. The installation of multiple persons is required, the installation is complicated, the total weight of the multifunctional lamp is up to 2.5Kg, the requirement for light weight is not met, and the cost is high. The existing cover type emergency brake has the defects that the cover and the base are of a split mounting structure, when the cover and the base are mounted with a vehicle, a chute is needed to be added on a vehicle wallboard, the cover is firstly detached from the base, then the handle is detached from the handle seat, the base of the emergency brake is connected with the bracket through a fastener, the bracket is mounted on the chute on the vehicle wallboard through the fastener, then the handle is mounted on the handle seat through the fastener, and then the cover is mounted back through the fastener. The installation of multiple persons is required, the installation is complicated, the number of the brackets is increased, the total weight reaches 2.2Kg, the requirement of light weight is not met, and meanwhile, the cost is high. The base is adopted for suspension type installation, the installation of the installation bracket is required to be added, the installation is more troublesome, and the total weight is heavier. When the emergency brake is pulled out and the vehicle is installed, the cover cap is required to be detached firstly, the two sides of the wallboard are separated and are installed by the fasteners, the assembly is troublesome, and the installation by a plu
