Door opening and closing durability test device

Abstract

The invention relates to the field of vehicle product testing, and specifically discloses a vehicle door opening and closing endurance test device. The vehicle door opening and closing endurance testdevice comprises a base with a supporting rod, a power rotating device, a rotating arm, a buffer arm and a handle fixture. The power rotating device is installed at the top end of the supporting rod,a first end of the rotating arm is connected with a rotating shaft of the power rotating device, and the rotating arm is driven by the rotating shaft to rotate on a horizontal plane around the first end of the rotating arm; the buffer arm is provided with a buffer device and is located on the same horizontal plane as the rotating arm, the first end of the buffer arm is hinged to a second end of the rotating arm and can be rotated on the horizontal surface; and the handle fixture is used for performing an opening and closing action of a vehicle door, and the handle fixture is hinged to the buffer device and can be rotated on the horizontal surface. The vehicle door opening and closing endurance test device provided by the invention can improve the test effect by simulating the actual opening and closing of the vehicle door by a user, can also reduce the instant impact force when the vehicle door is opened and closed, reduces the damage to the vehicle door, and improves the operation stability of the endurance test.

Description

technical field [0001] The invention relates to the technical field of automobile product testing, in particular to a door opening and closing durability test device. Background technique [0002] With the development of the automobile industry, users have higher and higher requirements for the performance of automobiles in all aspects. The car door is an important part of the car, which plays an important role in protecting the safety of the occupants. Because the door is used very frequently, it is necessary to ensure its reliability, durability and operating comfort. This requires the use of test devices in the car production process. Door durability is tested. At present, there are some automobile door durability test devices on the market. These devices have the function of testing the durability of automobile doors to a certain extent, but basically realize the opening and closing of the car door through the expansion and contraction of the cylinder. The degree of si...

Problems solved by technology

The flexibility of this scheme is poor, and it is difficult to meet the test requirements of different models. The front and rear doors of some models cannot be tested at the same time, which affects the test efficiency.

[0005] (3) A kind of automobile door lid durability test stand, mainly has the frame that supports vehicle body and installs automobile four-door opening and closing mechanism, automobile two-lid opening and closing mechanism, is installed on the four-door opening and closing mechanism of vehicle body both sides, is installed on The front and rear cover opening and closing mechanism of the car body, and the front and rear cover guide rail spring vacuum suction cup assembly installed on the cantilever rod of the front and rear cover opening and closing mechanism are not reasonable enough for the buffer design in the process of opening and closing the car door. Unevenness causes damage to the door handle and door sheet metal, which affects the test results

The technical solutions disclosed above all realize the opening and closing of the car door through the expansion and contraction of the cylinder, which cannot effectively simulate the force state of the car door when the user actually opens and closes the car door.
