Description

Glass safety device of a door for an automobiles}

The present invention relates to a glass safety device for a car door. More specifically, when an object is caught between the glass and the door chassis, the pinch force of each lifting and lowering stroke occurs in the same manner so that reverse rotation is possible. The invention has been invented to improve the safety as well as satisfy the law by varying the delay interval length.

Recently, most automotive door glasses adopt a method of opening and closing using a window regulator motor.

As shown in FIG. 1, the door glass opening and closing device is provided with glass guides 3 for guiding the lifting and lowering of the glass 2 on both inner side surfaces of the door panel 1 in a vertical direction, and an intermediate part thereof. The window regulator motor 41 and the wire 42 provided between the both ends of the movable body 46 which are slidably installed in the inside of the guide 45 and the window regulator motor 41, and the limit for detecting the lifting point of the glass lifting end point are provided. Hall sensor 44 and the guide for detecting the clamping pressure of the glass (2) as an electrical signal through the pressure detection of the switch 43, the wire 42 to directly transfer the power of the motor 41 to the movable body ( A regulator assembly 4 composed of 45 is installed, and an up / down switch 5 for driving up / down the window regulator motor 41 is installed around the driver's seat and on one side of the door panel, and the up / down Switch (5) Hall sensor 44 and the window regulator motor 41 has a structure in which connection with the control unit (6) provided with a electronic control unit and a motor driver.

Therefore, when a driver or the like operates any one of the up / down switches 5 provided in the vicinity of the driver's seat or on one side of the door panel 1, the motor driving unit (1) in the electronic control unit 61 in the control unit 6 is operated. Since a predetermined output signal (that is, a drive signal having a predetermined frequency) is generated at 62, the window regulator motor 41 is rotated in the forward or reverse direction so that one end of the glass regulator 2 together with the movable body 46 is formed at the center of the bottom of the glass 2. The fixed wire is rotated in the forward or reverse direction to open and close the glass 2 by lifting or lowering together with the movable body 46 for sliding the guide 45.

On the other hand, when the driver or the like operates the up switch 5 and the glass is being raised and lowered, the hall sensor 44 makes an electrical signal through a method of detecting the pressure of the wire 42 by the stroke waveform of the motor 41. (That is, a square wave signal) is detected and output to the electronic control unit 61 in the control unit 6, if the part of the human body between the door chassis 11 and the glass 2 during the lifting of the glass 2; In a steady state in which a predetermined object including the back is not caught at all, the output waveform of the square wave output from the hall sensor 44 is in a state of 'high' and 'low' time as shown in FIG. When the object is caught, as shown in FIG. 2 (b), since the square wave output waveform in which the 'high' time is delayed from the normal time is output from the hall sensor 44 and input to the electronic control unit, the electronic control unit The magnitude of the delay interval of this waveform at It is compared with the value which will be to not less than the value which an object is recognized to Empty glass insert and automatically lowered by being rotated by the lifting motor 41 is reverse.

At this time, the clamping pressure of the wire for the reverse rotation of the motor, that is, the clamping input under the condition that the motor is reverse rotation is prescribed by the law less than 10Kgf.

However, the glass 2 installed in most automobiles has one side inclined at a predetermined angle and the upper portion is curved with arcs having different diameters, that is, the one inclined surface 21 and the upper one side 22 of each section. Since the angles of the upper end face 23 are different from each other, the clamping forces f1, f2, and f3 have a large difference even under the load of the same motor, and the order of occurrence of the pinch is also inclined on one side 21 and upper side 22 on the upper side. (23) occur in the order of magnitude, and the magnitude of the jam load is also in the order f1 → f2 → f3.

Therefore, even in the delay section of the same value, the load of the clamping force (f1) applied to one side of the inclined surface 21 is too large, there is a problem that can not satisfy the law.

The present invention has been made to solve the above-mentioned problems, and when the object is caught between the glass and the door chassis, the lifting force is divided by each section of the lifting stroke to satisfy the regulations and ensure safety. It is an object of the present invention to provide a glass safety device for a car door.

The object of the present invention described above is provided with glass guides for guiding the lifting and lowering of the glass in both the inner side surfaces of the door panel in the vertical direction, and in the middle part thereof, a window regulator motor, a wire, and the limit switch for detecting the lifting point of the glass lifting point The regulator assembly consists of a hall sensor and a guide that detects the clamping pressure of the glass by detecting the pressure of the wire.Up / down switches for driving the window regulator motor up / down are installed around the driver's seat and on one side of the door panel. In the glass safety device of the automobile door is installed, the up / down switch, the hall sensor and the window regulator motor is connected to a control unit including an electronic control unit and a motor driving unit,

In the electronic control unit within the control unit, when the glass is lifted and operated, the one side inclined surface, the upper one side and the uppermost side of the glass are distinguished, respectively, and the delay length and size for each section are one side inclined delay length (D1) <upper one side delay length. This can be achieved by setting in order of (D2) <

Therefore, the clamping force received by the object sandwiched between the glass and the door chassis is the same in each section of the glass, which satisfies the regulations that the motor reverses when the clamping force is 10Kgf or less. It can be.

It is characterized in that it is controlled to.

Referring to the effects of the present invention configured as described above are as follows.

First, when the driver or the like operates the up switch 5, the hall sensor 44 detects a stroke of the motor 41 driven by a pulse control signal through a method of detecting a pulling pressure of a wire. The waveform is detected and output to the electronic control unit 61 in the control unit 6. If the glass 2 is lifted, a predetermined part of the human body is included between the door chassis 11 and the glass 2. If an object is jammed, regardless of the size or position of the object, the preconditioning control unit 61 controls the motor 41 to a delay section set in itself so as to have a different length for each section of the glass 2. Done.

That is, since the length of the delay section of the hall sensor 44 is added to each of the lifting strokes as shown in FIGS. 5 (a)-(c), the clamping pressure of each section is controlled in the same manner.

In other words, when the glass 2 is fitted to the chassis in the order of the one side inclined surface 21 → the upper one side 22 → the top end 23, the delay length is higher than the one side inclined surface 21 delay length D1. 22) By controlling the delay length D2 to be large and controlling the delay length D3 of the upper end 23 to be larger than the upper one side 22 delay length D2, the clamping force received by the object is determined by the glass 2 ) Will receive the same pressure at each section position.

Therefore, since the jamming load generated in each section of the glass 2 is the same, when the object caught between the glass 2 and the door chassis 11 receives a clamping force of 10 Kgf or less specified by the law, the glass Since the window regulator motor 41 that raises and lowers (2) accurately rotates and descends, it is possible to prevent damage and injuries due to a certain object being caught between the glass 2 and the door chassis 11. will be.

As described above, according to the present invention, the glass and the door are set by setting the delay length for each section of the glass in the order of one side slope delay length D1 <upper one side delay length D2 <top edge delay length D3. When an object is caught between the chassis, the clamping force received by the fire body can be the same in each section of the glass, so that the clamping force can satisfy the law that the motor reverses when the clamping force is 10Kgf or less. It can be secured.
