Description

Automobile door damage prevention structure

The present invention relates to a door damage preventing structure of a vehicle, and more particularly, to a door damage preventing structure of a vehicle to improve the structure of the door to protect the door from an external shock when the door is opened.

In general, the vehicle body is an important factor to ensure the safety of the vehicle by testing the front and side impact to ensure the safety of the passenger in the event of a crash, and already in each country As it is legalized and used as a large item such as import regulation, it has been required to minimize the deformation of the door during external impact.

1 and 2 are views illustrating a door installed in a vehicle body, and the door 10 that can be opened and closed while being in close contact with a side seal (not shown) of a vehicle includes a door out panel 12 and a door inner panel 14. The door glass 6 is fused to each other to have a constant space portion 10a, and is raised and lowered in accordance with the operation of a regulator in the space portion 10a.

A door trim 18 is attached to one side of the door inner panel 14, and a slip pull (not shown) is inserted into the door trim 18 to absorb impact force during an external collision. The waste line 20 is fixed to the door out panel 12 by the hook 22 so as to prevent damage to the door.

In the conventional door configured as described above, when the vehicle collides toward the door 10 side, the door out panel 12 and the fused door inner panel 14 are simultaneously crushed and pushed toward the passenger side. At this time, the shock force was absorbed to the maximum by the spool puller inserted into the door trim 18 to protect the passengers.

In addition, the waste line 20 fixed to the door out panel 14 by the hook 22 prevents damage to the door by absorbing an impact when the door 10 hits a wall or another vehicle when the passenger gets off.

However, because the waste line is fixed to the door out panel as described above to absorb the impact force of the door when the door is opened, the weak impact force can prevent the door from being distorted with only the waste line, There was a problem that the door is damaged because it is not absorbed.

The present invention is to solve the above problems, the object of the present invention is to improve the structure of the door so as to absorb the external impact force when the door is open enough to prevent the door damage of the car can sufficiently protect the door from other vehicles To provide structure.

Features of the present invention for achieving the above object, the door out panel and the inner panel is provided in the inter-fused door and the space portion so as to have a space portion is provided to prevent the distortion of the door out panel when opening the door. In the door damage prevention structure of the vehicle, the through-hole is formed in the door line and the waste line fixed to one surface thereof, respectively, the shock absorbing member is provided in the space portion so that a portion protrudes through the opening when the door is opened, The shock absorbing member is provided by driving means for providing a driving force to protrude the shock absorbing member longitudinally relative to the door to absorb the impact force applied to the door.

The shock absorbing member according to the present invention is achieved by being compressed rubber.

The driving means according to the preferred embodiment of the present invention is achieved by being provided with a drive motor installed in the space portion of the door and providing a driving force, a pair of racks engaged with the drive motor, and a trimmer link connected to the rack, respectively. do.

Hereinafter, described in detail based on the accompanying drawings for the door damage prevention structure of the vehicle according to the present invention.

In the configuration of the present invention for the same parts as the conventional configuration, the same reference numerals for convenience of description.

3 and 4 are views showing a door damage prevention structure according to the present invention, the door 10 is fused to each other so that the door out panel 40 and the inner panel 12 has a space (10a), the door A door trim 18 is attached to one surface of the inner panel 14, and a waste line 42 is fixed to the door out panel 40 by a hook 22.

Through-holes 40a and 42a are formed in the door out panel 40 and the waste line 42 so that their centers coincide with each other, and the wall surface of the door 10 when the door 10 is opened in the space part 10a of the door 10. Alternatively, a shock absorbing member 44 is installed to absorb the impact force to prevent crushing of the door out panel 40 from an external vehicle, and the shock absorbing member 44 is provided with driving means for providing a driving force to protrude it to the outside. This is installed.

The shock absorbing member penetrates through the through-holes 40a and 42a of the door out panel 40 and the waste line 42 and is made of compressed rubber to sufficiently absorb the impact force, and the driving means is a space portion 10a. A pair of racks 54 and racks 54 engaged with the gears 52 and the gears 52 press-fitted to the rotation shafts of the drive motor 50 and the drive motor 50 installed therein are linearly moved in opposite directions, respectively. One end is provided with a trimming link 58 connected by a hinge pin 56, respectively.

When described in detail with reference to Figure 3 the operation of the battery fixing structure of the vehicle according to the present invention configured as described above.

When the driver or passenger in the vehicle gets off, when the door 10 is opened, the power of the battery 62 is transmitted to the driving motor 50 as the door switch 60 is turned on and press-fits to the rotating shaft thereof. As the gears 52 rotate forward, the pair of racks 54 engaged with the gears 52 linearly move in opposite directions, respectively.

Thereafter, the trimmer link 58 connected with the rack 54 and the hinge pin 56 is opened, and the shock absorbing member 44 connected with the trimmer link 58 moves longitudinally with respect to the door 10. That is, the shock absorbing member 44 is protruded into the through-holes 40a and 42a formed in the door out panel 40 and the waste line 42, respectively, to sufficiently absorb external impact force and to open the door 10. To protect.

When the door 10 is closed, the door switch 60 is grounded in a close to open manner, thereby rotating the driving motor 50 and the gear 52 pushed into the rotating shaft thereof in reverse, and the gear 52 The shock absorbing member 44 protruding into the through holes 40a and 42a is retracted as the rack 54, which is engaged with the rod 54, moves in the reverse direction, and the inclined link 50 is retracted inward. It is pulled into and returned to the initial position.

According to the door damage prevention structure of the vehicle according to the present invention as described above, it is possible to sufficiently protect the door from other vehicles by improving the structure of the door to sufficiently absorb the external impact force when the door is opened.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
