Problems solved by technology

[0007] That is to say, in principle, the door is prohibited from opening and closing while the vehicle is running, so for this kind of device that performs locking switching in conjunction with the opening and closing of the door, there is no need to worry about releasing the door lock while the vehicle is running. In a locking device that performs lock switching through a solenoid or the like independently of the door opening and closing state, there is a possibility that the lock is released due to an erroneous input of a lock release command while the vehicle is running.

Embodiment Construction

[0029] Preferred embodiments of the present invention are described based on the drawings. The embodiment shown here is a structure for locking a sliding door type vehicle door, and the locking means of the present invention can also be effectively applied to other types of doors, such as sliding door type or folding door type door locking.

[0030] exist figure 1 In the left and right sliding doors 10, the locking unit 30 is provided at a position immediately above the sliding door 10 (in the illustration, a position near the door end). Moreover, the two sliding doors 10 are locked in the fully closed position through the locking assembly 30 .

[0031] Such as Figure 3 ~ Figure 5 As shown, the lock unit 30 is provided with a vertical mounting plate 32, and the mounting plate 32 is fixed to the structure side with bolts or the like not shown.

[0032] At the predetermined position of the above-mentioned mounting plate 32 (in image 3 middle left lower part) is fixed by it...

Abstract

To provide a door lock control method for a vehicle, which can positively prevent unlocking of a door during traveling of the vehicle, to thereby improve the safety of door locking, and to provide a door lock device. Door lock control for the vehicle is carried out by using a locking means which energizes a lock switching pin to a locking position by the force of a spring, and switches the lock switching pin to an unlocking position by supplying electric power to a solenoid (54). When the traveling speed of the vehicle is below a constant value, a control device (70) on-off-controls power supply from a power source (80) to the solenoid (54), based on a command input from outside. When the traveling speed of the vehicle is equal to or larger than the constant value, a vehicle speed detecting switch (81) is operated, and power supply from the power source (80) to the solenoid (54) is inhibited in spite of the input of the command.

Description

technical field [0001] The present invention relates to a locking control method and a locking device for locking a door provided on a railway vehicle or the like at a fully closed position. Background technique [0002] In the past, fluid pressure such as air pressure was used as a driving source as a means for opening and closing doors of railway vehicles. In recent years, from the viewpoint of reducing driving sound, controlling responsiveness, or improving maintainability , and developed a railway car door opening and closing device using an electric drive source such as a motor. [0003] In such a device that uses a motor as a drive source, after the door is completely closed, it is necessary to cut off the power supply to the motor in order to prevent the motor from burning out or to save power. If the motor is turned off, the output shaft will be free. Rotating to allow the door to move freely, so it is necessary to additionally provide a locking device for keeping t...
