Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention is further described in detail:

[0016] The invention relates to an electric auxiliary lock for a high-speed rail vehicle electric double-open plug-and-pull door system, which includes a lock body 1, on which a reduction motor 2, a planetary reduction clutch mechanism 3, an inner swing arm 5, and a reduction motor 2 are sequentially arranged. Connect the planetary deceleration clutch mechanism 3, the planetary deceleration clutch mechanism 3 is connected to the inner swing arm 5, and the lock body 1 is also provided with a deadbolt 6, and the deadbolt 6 is arranged on one side of the inner swing arm 5, when the door leaf needs to be locked, The reduction motor 2 reduces the rotating speed through the planetary deceleration clutch mechanism 3, and then drives the inner swing arm 5 to rotate. When the inner swing arm 5 rotates to the lock, the inner swing arm 5 contacts the lock tongue 6 and rotates the...

Abstract

The invention relates to a motor-driven auxiliary lock which comprises a lock body. A speed reducing motor, a planet speed reducing separation and reunion mechanism, an inner swing arm and a spring bolt are sequentially arranged on the lock body. The planet speed reducing separation and reunion mechanism comprises a box body. A sun wheel, a planet wheel, a planet carrier, a ratchet wheel and ratchets are arranged in the box body. A resetting spring is arranged on a rotating shaft of the ratchets, the planet wheel is arranged on the planet carrier, the planet wheel is meshed with the inside of the sun wheel and meshed with the outside of the ratchet wheel, the sun wheel is in rigid connection with the speed reducing motor, the planet carrier is in rigid connection with the inner swing arm, the inner swing arm is in contact with the spring bolt, and a one-way bearing is arranged on a connection shaft of the sun wheel and the speed reducing motor. Compared with the prior art, the lock utilizes the planet speed reducing separation and reunion mechanism to drive the spring bolt to conduct pressurization, and the airtight effect is good. The planet speed reducing mechanism is adopted to greatly reduce the speed reducing ratio of the speed reducing motor at the front end and reduce the torque of the front end, electric driving is not required in the pressure maintaining and releasing stages after pressurization, and the service life of the motor is greatly prolonged.

Description

technical field [0001] The invention relates to a rail vehicle door lock, in particular to an auxiliary lock for a high-speed rail vehicle electric double plug-and-pull door system. Background technique [0002] Electric double sliding doors are mainly used for the doors of high-speed trains. At present, the electric double sliding door system mainly meets the door system strength requirements, noise requirements and sound insulation and heat insulation indicators, but there is no corresponding indicator for the air tightness of the vehicle. When the vehicle enters and exits the tunnel and intersects with the 200km / h train, the air pressure will cause discomfort to passengers such as tinnitus. Therefore, it is particularly important to pressurize the door to maintain airtightness. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide an electric auxiliary lock with good airtightness, small size and low failure rate. [000...
