Abstract:
Disclosed is a shock absorber for a vehicle which includes a bumper beam which is formed in the shape of a beam in which the hollow cross section thereof is extended in the width direction of a vehicle and a crash box which is placed between a rear surface and a vehicle body in both sides of the bumper beam. The rear surface on both sides of the bumper beam includes an opening which is formed to connect to the hollow cross section and a rib which is formed in an opening in a width direction. The crash box includes a front end which is extended to the inside of the hollow cross section by being inserted through the opening while being inserted into the rib and a rear end which is mounted on the vehicle body, thereby improving the collision performance of a vehicle.
Abstract:
PURPOSE: A bumper assembly for vehicles is provided to improve the durability by mounting each crash box to face front and lateral sides from the front surface of the vehicle, dispersing and absorbing shock energy, and minimizing the deformation of a vehicle side member. CONSTITUTION: A bumper assembly (100) for vehicles comprises a first side member (110), a second side member (120), a fender member (130), a member flange (140), a mounting flange (150), a first crash box (160), a second crash box (170), and a bumper beam (180). The member flange is connected to the front end of the first and second side members. The rear end of the first and second crash boxes are connected to the mounting flange. Both sides of the bumper beam are connected to the front end of the first and second crash boxes.
Abstract:
PURPOSE: A crash box structure for a car is provided to improve an absorption rate of impact energy in a low-speed crash because the bead of the peripheral surface of a crash box is formed at an angle. CONSTITUTION: A crash box structure for a car comprises a crash box(300) which is installed between side members(100) and a bumper(200). An outer part(320) of the crash box is formed at an angle so that the diameter of the crash box gradually increases from the rear section thereof connected to the side members to the leading end thereof connected to the bumper.
Abstract:
A structure for coupling a roof panel and a front pillar for a vehicle is provided to couple the roof pane with the front pillar using a structural adhesive during a laser welding such that a problem related to the right track of the vehicle is easily solved. A structure for coupling a roof panel(10) and a front pillar(30) for a vehicle comprises a bonding member(50). The bonding member bonds a contact area, which is prepared between one side of a front portion of the roof panel and an external top end of the front pillar. The bonding member is a structural adhesive used to ensure the strength of the contact area between the roof panel and the front pillar. The front distal end of the roof panel and the top of the front pillar is spaced apart by a certain interval to prevent disgusted noise from being generated between the roof panel and the front pillar.
Abstract:
A mounting device of a spare tire is provided to remarkably reduce hazard of a secondary accident by preventing damage to a fuel tank due to the spare tire. A mounting device of a spare tire includes an impact sensor(7), a fixing member(9), and a fixing body(12). The impact sensor is disposed at a rear part of a trunk(3) to detect a rear collision of a vehicle to transmit collision data to a controller(6). The fixing member is fixed in the trunk to receive power from the controller to vary polarities of upper and lower parts. The fixing body is magnetically coupled to an upper part of the fixing member and threadedly engaged with a fixing bolt. The fixing body is formed of a permanent magnet having a nut hole to which the spare tire is fixed. The fixing bolt fixes a bead part of the spare tire to the fixing member.
