Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a finger pinch prevention device that is installed near the door of an automobile to prevent a user's fingers from being pinched.

When a passenger gets in or out of a car, they often hold on to the edge of the door or the doorway, for example, and push the door closed from the outside before they can pull their hands back, causing their fingers to become loose. Often gets pinched and injured. Furthermore, even after children have boarded the vehicle, they often keep their hands on the edges of the doorway, and their fingers are often caught when someone outside carelessly closes the door. In any case, the car door is designed to close completely when closed forcefully, which can pinch your fingers and cause injury.

The present invention was developed in view of the above circumstances, and its purpose is to electrically detect when a hand is on the edge of a door or entrance, and prevent the door from closing completely. An object of the present invention is to provide a device for preventing fingers from being pinched, which prevents injuries caused by fingers being pinched.

The present invention has been made to achieve this purpose.
A touch sensor that responds to human body contact is placed around the door and/or the doorway, and a judgment circuit is provided that receives the output from the touch sensor and the output from the door switch, and the output of the judgment circuit is In addition to providing a control circuit to control the actuator installed on each door,
A finger pinching prevention device for an automobile door, characterized in that it is equipped with a display device that displays the state, and when a hand is placed on the periphery of the door or the periphery of the doorway, an actuator works to completely close the door. As a result, a gap at least the diameter of the finger or larger exists, and the closed door becomes ajar, preventing the finger from being pinched too hard and causing injury.
This condition is notified to the driver by a display on the display device, and the vehicle is not driven with the door partially open.

Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 1 denotes a touch sensor, and the touch sensor is disposed around the periphery of each door and the entrance/exit of an automobile. A judgment circuit 2 is connected to this touch sensor, and the judgment circuit receives a signal from the touch sensor and judges its state. A conventionally used door switch 3 for detecting an ajar door is also connected to this judgment circuit 2, and also detects and judges the state of the door.

A control circuit 4 is connected to this judgment circuit, and a display device 5 and an actuator 6 are connected to the control circuit. The control circuit 4 receives the signal from the judgment circuit 2 and causes the display device 5 to display a status display, and depending on the status, drives the actuator 6 to correspond to the status.

The touch sensor 1 may be continuously attached to the periphery of each door 11 of the automobile 10 as shown in FIG. Set up

As shown in FIG. 3, the actuator 6 is attached to the hinge portion of each door 11, for example, and prevents the door 11 from being completely closed when there is an inconvenience or danger to the door 11 from closing. There is.

That is, as an example of this actuator, as shown in FIG. One end is rotatably fixed by a fulcrum 15, and a gear 16 is formed at the other end.
A lock hinge 18 having a gear 17 that meshes with the gear 16 is rotatably mounted on a fulcrum 19, and is formed so that the lock hinge 18 projects approximately vertically when rotated through approximately 90 degrees. In addition, code 20
is an automobile body iron plate, and 21 and 22 are mounting screws.

The finger pinch prevention device of the present invention configured as described above is such that when a user or a passenger in the same vehicle puts their hand on the peripheral edge of the door 11 or the peripheral edge of the entrance/exit, the touch sensor 1 detects this. is detected and input to the judgment circuit 2 with a predetermined signal. When it is determined based on the signal obtained by this judgment circuit that it is dangerous to close the door now, the actuator 6 is driven via the control circuit 4 to prevent the door from being completely closed.

In other words, the electromagnetic solenoid 12 is excited by the control from the control circuit 4, and the plunger 1
3 is retracted, the drive plate 14 rotates by a predetermined angle about the fulcrum 15, and the lock hinge 18 is rotated by the gear 16 at the other end, and pops out to the position shown by the imaginary line in FIG. Even if the door 11 is closed in this state, the door will not close completely due to the protrusion of the lock hinge 18, and even if your hand gets caught, you will not be injured.
In short, if your hand is in the position where the door is held when you close the door, the lock hinge 18 will be in a protruding state, and if the door position, which is normally completely closed by the lock hinge, is on line A, the protrusion of the lock hinge will cause the lock hinge 18 to protrude at a predetermined angle. With Q, the door will close only at the position of line b, and it will be in a half-open state, so you won't be able to hold your hand. By leaving the door ajar, the status is displayed on the display and the driver is notified of this, and the driver does not leave the vehicle with the door ajar, thereby improving driving safety.

As explained above, the finger pinching prevention device for an automobile door according to the present invention includes a touch sensor disposed around the periphery of the door and the periphery of the entrance, a judgment circuit that receives a signal from the touch sensor, and a control circuit. The control circuit is configured to drive an actuator attached to each door, and if a hand is on the touch sensor, that is, if the hand is in a dangerous position, it will be activated. This device detects the door and drives the actuator via the control circuit so that the door can only be closed when it is ajar, eliminating the risk of fingers getting caught and also detecting whether the door is ajar. Therefore, it has an excellent effect of being excellent in safety.
