Description

Mechanical Door Guard for Automobile}

The present invention relates to a mechanical door guard for a vehicle, and more particularly, in order to prevent door scratches that may occur while opening the door of the vehicle, it is displayed on the outside of the vehicle only when the door is opened, so that it does not have any adverse effect on the actual appearance, This technology relates to an improved mechanical door guard for a vehicle that is mechanically configured to solve the disadvantages of electronic systems such as inflow of water such as car wash, rainwater, and complicated electric wire and battery exchange without changing the structure of the vehicle itself.

Vehicle door guards are intended to prevent door scratches that may occur while opening their own vehicle doors. Door scratches are scratches that occur on one's own vehicle and other vehicles when the vehicle's door is opened and hit by the edge of the door, and this is a part that everyone cares about and often occurs. The product currently sold and used is a method of attaching a sponge to the edge of the vehicle door (the part that is likely to be scratched). However, such a sponge-type door guard is not looking good in appearance, affects air resistance (aerodynamic power) when driving, and may be uncomfortable and easily detached when washing the car. In addition, if the entire edge of the door is not covered with a sponge, certain parts will not be protected. In addition, when the sponge-type door guard is removed, it is difficult to remove it because marks remain.

On the other hand, the door guards for vehicles released in about 2010 by Ford of the United States were not sponge-type, but were installed inside the vehicle doors. Since this is visible only when the door is opened, it is possible to solve the disadvantages in appearance and problems such as washing and removal of the car, but since the door plate must be pierced inside the vehicle door, it must be installed by the car company itself, not the consumer. Therefore, maintenance such as repair is difficult and there is a concern that there are many residuals. Above all, since the door plate itself is processed, the rigidity of the vehicle is deteriorated and the installation cost is largely consumed. In addition, since this product uses an electronic mechanism such as a motor, there is a risk of leakage into the door guard by car washing or rainwater. At the time of development of Ford's door guard, one car model equipped with a door guard was released, but it has not been installed since the year it was launched, and it has never been installed in other car models. This is probably due to the problem pointed out.

Looking at the conventionally disclosed document on the door guard for a vehicle, as in Korean Patent Publication No. 10-1594273, a door checker disposed inside the vehicle door and horizontally moving in conjunction with the opening and closing operation of the vehicle door; A rotation cam that is rotatably disposed inside the vehicle door and rotates in association with the horizontal movement of the door checker; An operation rod disposed inside the vehicle door and having one end in contact with the rotation cam and moving in a longitudinal direction by rotation of the rotation cam; Arranged as the other end of the movable rod, one end rotates in connection with the movement of the movable rod, and the other end is disposed as the other end of the movable rod protruding through the end of the vehicle door, and one end is interlocked with the movement of the movable rod. A guard portion which rotates and the other end protrudes through the end of the vehicle door; A control unit disposed on the guard unit to measure a distance from a neighboring vehicle and output a signal corresponding thereto; And an alarm unit configured to output a warning signal in response to an output signal from the control unit.

However, even in the conventional literature, the disadvantage of the Ford's door guard cannot be solved because the door steel plate is still required to be installed inside the vehicle door.

Next, the folded portion 30 includes a plurality of link members 31 and a torsion spring 32 positioned between the link members 31 so that the link members 31 are folded or unfolded with each other.

The link member 31 may be composed of a first link member 31a, a second link member 31b, and a third link member 31c, as shown in FIG. 1, and the torsion spring 32 Is a first torsion spring (32a) connecting the first link member (31a) and the second link member (31b), and connecting the second link member (31b) and the third link member (31c) It may be composed of a second torsion spring (32b).

When the door of the vehicle is closed, the link member 31 has one end in contact with the vehicle b-pillar, and the other end is fixed to the main body 20. That is, the free end of the first link member 31a may contact the b-pillar of the vehicle, and an end of the third link member 31c facing the second torsion spring 32b is the main body ( It is fixed at 20).

The first link member 31a is formed to be bent 90° (one direction) or 180° (both directions, 90° each) in a direction in which the first torsion spring 32a is folded, and further includes a restoring member. The bend can be restored. The restoring member may secure a space in a direction in which the folding part 30 is unintentionally bent by the tension spring 35 as the door of the vehicle is opened and closed.

In addition, the first link member (31a) is a spring connecting two link members of the 1-1 link member, the 1-2 link member, the 1-1 link member and the 1-2 link member. Can be configured. In this case, the direction in which the 1-1 link member and the 1-2 link member move will be different, and specifically, the 1-2 link member is 90° from the angle of the 1-1 link member. It moves in the direction of rotation. Conventionally, the movement of the first link member 31a was only possible in the y-axis, but the movement in the x-axis may be possible as the first link member is separated into two link members. This is because when the door of the vehicle with the door guard installed is closed in an open state, the door guard is fastened to the door and the folding part 30 is provided in a slightly protruding form before closing. This is to secure a movable space in the form/structure of the folded portion 30 when not touched. Meanwhile, the structure of the first link member 31a described above is applicable to the second link member 32b and the third link member 33c.

The torsion spring 32 may be replaced by mechanisms supporting the rotation of the link member 31, and the first torsion spring 32a and the second torsion spring 32b are not in the same direction and are It is installed in a symmetrical shape. At this time, the elastic modulus of the torsion spring 32 is higher than that of the spring 22.

During operation, when the door is closed, the torsion spring 32 is compressed so that the link member 31 is folded, and when the door is opened, the torsion spring 32 is restored. The link member 31 is provided to be unfolded. In this case, the first link member 31a to the second link member 31b are formed to overlap each other.

In addition, the folded portion 30 includes a wheel 33 positioned at a free end of the link member 31. Specifically, the wheel 33 is located at the free end of the first link member 31a, as shown in FIG. 2, to reduce the friction with the part in contact with the b-pillar when the door of the vehicle is closed, and the torsion When the spring 32 is compressed, it is provided to move smoothly on the vehicle body.

As shown in FIG. 2, the wheel 33 is formed in a structure in which the central axis of the wheel 33 can be changed so that the outer circumferential surface is placed in a direction parallel to the contact surface of the b-pillar. Otherwise, since the wheel 33 and the b-pillar are not in close contact, the amount of frictional force applied may be reduced, resulting in slipping.

In addition, the wheel 33 is a main wheel, two auxiliary wheels positioned to face each other on the outer circumferential surface of the main wheel and positioned to surround the main wheel, and the two auxiliary wheels connected to the lower end of the two auxiliary wheels. It may be composed of an elevating spring that moves the wheel up and down. Here, the central axes of the main wheel and the auxiliary wheel may be positioned to cross each other.

In addition, the folded portion 30 includes a fixing portion 34 fixed to the body portion 20, and a tension spring 35 connecting the link member 31 and the fixing portion 34 , Even when the link member 31 is bent laterally by an external force, it is formed to be restored to its original state by the tension spring 35.

The fixing part 34 further includes a spring between the tension spring 35 and the body part 20, and absorbs a shock primarily before the juice spring 221 is compressed, and the buffer member 10 It can primarily protect the state that is fastened to the door. In this case, the additionally included spring is different from the elastic modulus of the juice spring 221.

The tension spring 35 is installed in an elongated state so that an elastic force is always generated in its original state, so that breakage between the folded portion 30 and the body portion 20 can be prevented.

Meanwhile, the contact surface of the link member 31 and the fixing part 34 is formed as a radially inclined beveled surface 36, so that even if the link member 31 is bent, it can be restored more stably. That is, the inclined surface 36 is positioned around the tension spring 35, so that when the link member 31 is excessively bent or twisted by an external force, it can be induced to be restored to its original state.

In addition, the folded portion 30 is the third link member (31c) between the second torsion spring (32b) and the tension spring (35), which is the torsion spring (32) closest to the fixing portion (34). ) And a stopper 37 provided in the form of a protrusion protruding outward.

The stopper 37 is provided at the uppermost position of the tension spring 35 when the vehicle door is closed, and the elastic modulus is low when the torsion spring 32 is compressed after the spring 22 is compressed. It will be possible to prevent the tension spring 35 from being bent. That is, the stopper 37 is formed to come into contact with the main body 20 only when the door of the vehicle is completely closed, and when an unintended force is generated on the wheel 33 due to an external force, the stopper 37 ) Is formed so as not to come into contact with the main body 20.

When the door of the vehicle is closed, looking at the operation mechanism centering on the folded portion 30, the wheel 33 abuts the b-pillar to generate a frictional force, and the tension spring 35 and the spring are due to the frictional force. The portion 22 is compressed, and accordingly, the fixing portion 34 and the tension spring 35 are inserted into the body portion 20. Thereafter, due to the frictional force generated by the wheel 33, the torsion spring 32 having the highest elastic modulus is compressed and the link member 31 is folded.

At this time, the wheel 33 is in contact with the b-pillar and needs to continuously generate a frictional force, but if it is rotated in a direction that does not generate the frictional force, the spring 22 may not be compressed, so that the wheel 33 rotates. The direction may be fixed in a direction capable of generating frictional force by contacting the b-pillar.

Hereinafter, with reference to FIGS. 5 to 8, changes in the vehicle mechanical door guard according to the present invention when the door of the vehicle is opened and closed will be described.

In this case, the buffer member 10 is in a state of being inserted into the inside of the door, and the main body part 20 has the rack assembly 21 positioned at the lowest side so that the spring part 22 is maximally compressed. , The folded portion 30 is in a state in which the torsion spring 32 is completely compressed and the link member 31 is folded. At this time, the movable block 213 is located at the first end of the groove part 2111, and the stopper 37 is located so as to contact one surface of the main body part 20.

6 is a view showing a mechanical door guard for a vehicle in a state in which the door of the vehicle is opened. When the mechanism during the opening is described in detail, first, the friction force generated when the wheel 33 and the b-pillar come into contact with the vehicle door is released, and the body part 20 is restored as the compressed spring part 22 is restored. The rack assembly 21 moves to the top. The pinion part 23 rotated by the upper movement of the rack assembly 21 rotates the driving arm 24 so that the buffer member 10 surrounds the door edge of the vehicle. In addition, the folded portion 30 is the compression spring 35 and the torsion spring 32 is restored and the fixing portion 34 and the tension spring 35 that were inserted into the body 20 Moving to the outside of the main body 20, the link member 31 is unfolded. At this time, the movable block 213 is located at the second end of the groove 2111, and the stopper 37 is spaced apart from the main body 20.

7 is a view showing a mechanical door guard for a vehicle while the vehicle door is open and closed. When the mechanism during closing is described in detail, first, as the door of the vehicle is closed, the wheel 33 and the b-pillar come into contact with each other to generate a frictional force, and the tension spring 35 is compressed and moves connected to the fixing part 34. As the block 213 moves downward, it is inserted into the main body 20 and the juice spring 221 is compressed. Even when the protruding member 2131 of the movable block 213 is positioned at the second end of the groove 2111, the movable block 213 lowers the rack part 212 due to the continued frictional force. As the force is transmitted so that the rack unit 212 is lowered, the bus spring 222 is also compressed. In this process, the pinion 231 rotates as the rack unit 212 is lowered, so that the buffer member 10 is brought back into the door. In this process, the pinion part 23 rotated by the upper movement of the rack assembly 21 rotates the driving arm 24 so that the buffer member 10 is positioned to surround the edge of the door of the vehicle. In addition, the folded portion 30 is the compression spring 35 and the torsion spring 32 is restored and the fixing portion 34 and the tension spring 35 that were inserted into the body 20 Moving to the outside of the main body 20, the link member 31 is unfolded. At this time, the movable block 213 is located at the second end of the groove 2111, and the stopper 37 is spaced apart from the main body 20. 7 shows that in the above-described state, the torsion spring 32 is compressed while the door is continuously closed, and the link member 31 is completely folded to return to the state of FIG. 5.

8 is a view showing a mechanical door guard for a vehicle when an unintended external force (A) is applied. As the tension spring 35 is compressed due to the external force (A) as shown in FIG. 7, the moving block 213 connected to the fixing part 34 moves downward, and the tension spring 35 moves to the body The juice spring 221 is compressed by being inserted into the inside of the part 20. Accordingly, the protruding member 2131 of the movable block 213 is located at the lowermost end of the groove part 2111. However, since the external force (A) is unintended and is temporarily applied, no more force is transmitted so that the rack unit 212 and the pinion 231 are maintained in a fixed state, so that the driving arm 24 is It doesn't rotate.

In the mechanical door guard for a vehicle according to an exemplary embodiment of the present invention, the rack assembly 21 may be formed in the structure shown in FIG. 9.

When looking at the rack assembly 21 from the side, the rack frame 211 is formed in a rectangular parallelepiped, so that the rack part 212 is located at the lower part, and the pinion 231 is located on the upper surface of the rack part 212 Was deployed. However, since the mechanical door guard for a vehicle of the present invention is located between the b-pillar and the door, interference of the rear door may occur depending on the type of vehicle. In order to minimize the interference of the rear door, the upper surface of the rack frame 211 may be formed in a concave curved surface, and the pinion 231 may be disposed in a position adjacent to the folding part 30 with respect to the rack frame 211. I can. When the position of the pinion 231 is disposed adjacent to the folded portion 30, durability can be maintained since there is no need to change the size of the pinion 231.

The rack part 212 may be formed to protrude from the rack frame 211 to the outside by a certain portion. That is, when the main body 20 is formed smaller than the range in which the rack unit 212 is driven, only the rack unit 212 protrudes while the door guard is fastened to the door, thereby reducing the overall size of the vehicle door. While accommodating space, it will be able to maintain operational functions. Also in this case, since the rack unit 212 is retracted inward even when the door of the vehicle is closed and the door guard is separated, there is no relation to the drive or space of the main body unit 20. That is, it is provided in a structure capable of reducing the size of the main body 20, thereby minimizing restrictions on various types of vehicle space.

In the mechanical door guard for a vehicle according to an exemplary embodiment of the present invention, the driving arm 24 may be transformed into the structure shown in FIG. 10.

As shown in FIG. 10, the driving arm 24 is a spring housing 245 positioned between the horizontal rigid member 241 and the vertical rigid member 242, and inserted into the spring housing 245. Includes a compression spring 246 and a wedge part 247 inserted into the spring housing 245 to connect the horizontal rigid member 241 and the vertical rigid member 242 under the compression spring 246 can do. When the door of the vehicle is closed, the driving arm 24 is rotated adjacent to the b-pillar to lead the buffer member 10 into the door, so that the length of the driving arm 24 is accommodated according to the type of vehicle. Insufficient space to do so may cause failure of the driving arm 24. Accordingly, the vertical rigid member 242 of the driving arm 24 is provided to move up and down. Specifically, by forming a slot and a protrusion between the vertical rigid member 242 and the wedge portion 247, the protrusion moves within the slot so that the vertical rigid member 242 with respect to the wedge portion 247 Can move up and down. In addition, a compression spring 246 is provided on the top of the wedge part 247 so that the vertical rigid member 242 can move to its original state while the door of the vehicle is opened, and the vertical rigidity due to the narrow space when the door is closed. When the member 242 moves downward, the compression spring 246 is compressed, and when the door is opened, the compressed compression spring 246 is restored so that the vertical rigid member 242 can move back to its original state. At this time, the wedge part 247 is formed to transmit a rotational force from the horizontal rigid member 241 to the vertical rigid member 242 for transmitting the rotation of the pinion 231. That is, the wedge portion 247 is fixedly connected to the horizontal rigid member 241, and the vertical rigid member 242 is formed between the vertical rigid member 242 in a slot and protrusion structure with respect to the wedge portion 247. ) Is formed to move up and down.

It will be appreciated that the above-described technical configuration of the present invention can be implemented in other specific forms without changing the technical spirit or essential features of the present invention by those skilled in the art to which the present invention pertains.

Therefore, the embodiments described above should be understood as illustrative and non-limiting in all respects, and the scope of the present invention is indicated by the claims to be described later rather than the detailed description, and the meaning and scope of the claims and the All changes or modifications derived from the equivalent concept should be construed as being included in the scope of the present invention.
