Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an actuation device for rear tilting of a removable sunroof.

Conventionally, there is a sunroof in which an opening is formed in the roof surface of an automobile, etc., and a cover panel is removably fitted into the opening.In addition to opening and closing the cover panel, only the rear part of the sunroof is lifted to provide ventilation. For this purpose, it is provided with a hinge section at the front and a lifting and tilting device at the rear.

Normally, removable sunroofs like this need to be manufactured at low cost, so there are toggle latches, which are a simple mechanism that can be operated manually, or toggle latches, which are a bit more complicated, but are made using a combination of screws. There is a tilting device called a rotary latch that expands and contracts.

However, these tilting devices are located behind the opening, requiring the driver to reach one or both hands backwards to operate them, which can be very dangerous while driving, and toggle latches are usually unstable. There are many elements involved, and a locking device is required, and the operation of the rotary latch is not easy. This is because, as mentioned above, it is necessary to make the removable sunroof itself inexpensive, so there is a lack of consideration given to safety and operability.

For these reasons, in this project we have invented a removable sunroof tilting device that is as inexpensive as possible and has good operability.The main components of this device are springs and wires, and the wires can be remotely controlled, allowing the driver to Instead of having to use the steering wheel of a car and operating it far behind the vehicle, the system provides an operating handle close to the driver's hand and uses this to operate the tilting device.

This tilting device consists of a housing made up of two or three steps that can be expanded and contracted, and by combining this housing with the force of a spring, it can be raised, and it can be controlled by the operation of a wire. is extremely simple, and its parts can be manufactured at low cost.
