Description

Slip guide structure for preventing vehicle sliding door open and close overload}

The present invention relates to a slip guide structure for preventing overload when opening and closing the slide door of a van. More specifically, it prevents overload when opening and closing the slide door of a van, thereby preventing motors that open and close the slide door from being damaged due to overload. This relates to a slip guide structure with a new configuration to prevent overload when opening and closing the slide door of a van.

In general, a van has a spacious cabin to accommodate more passengers, and is equipped with a slide door to allow a large number of people to easily enter and exit the cabin. The slide door opens and closes the boarding entrance formed on the side panel of the van by sliding along a guide rail attached up and down to the vehicle body.

Additionally, the van is equipped with a locking device to detachably lock the slide door when the slide door is fully closed. When a typical vehicle slide door is closed, the closed state of the slide door is maintained by engaging the door latch of the locking device and the latch engaging piece, while pulling the lever provided on the slide door opens the door latch of the locking device and the door latch of the locking device. Since the engagement of the latch engaging piece is released, the slide door can be opened. In order to open the slide door, pulling the inner lever or outer lever provided on the slide door releases the engagement between the door latch of the locking device and the latch engaging piece, allowing the slide door to be opened.

Meanwhile, recently, there are many vans equipped with an automatic door opening and closing device that opens and closes the slide door automatically rather than manually, and in these vans with automatic slide door opening and closing, the automatic opening and closing motion of the slide door is controlled by the guide rail of the van. The automatic locking device for this purpose is equipped with parts such as a drive motor.

When the drive motor is driven, the clutch operates to open and close the slide door. That is, the clutch has a driving clutch plate connected to the motor shaft of the drive motor and a driven clutch plate connected to a chain provided on the slide door of the van, and the driving jaw of the driving clutch plate is engaged with the driven jaw of the driven clutch plate. When the driving clutch plate rotates, the driven clutch plate rotates to open and close the slide door by the chain.

However, in the case of a slide door opening and closing structure that opens and closes an existing slide door, if an overload occurs when opening and closing the slide door, the overload is transmitted to the motor, which is the main part that opens and closes the slide door, due to the overload applied to the slide door. There is a problem of damage, and if the motor, which is the main part responsible for the opening and closing operation of the slide door, is damaged due to overload, maintenance such as replacement is cumbersome, and there are various problems such as the lifespan of the main part for opening and closing the slide door being shortened.

When the weather is cold, such as in winter, the surrounding parts such as wires, chains, or door rails connected to the slide door and the slide door freeze, causing the slide door to freeze on the surrounding parts when opening and closing the slide door, making it difficult for the slide door to open or close properly. As a result, the driver has to repeatedly drive the motor to open and close the slide door, and major parts such as the motor are overloaded, causing damage to the motor, cutting and deformation of cables and wires, deformation of the rail, and wear of the reducer. There is a problem with major parts being damaged.

Therefore, in the case of overload when opening and closing the door, a fundamental measure is needed to prevent deformation or wear of the door structure because the rotating force from the motor is not transmitted to the drive structure that opens and closes the door.
