Description

Endurance test equipment of inside handle for automobile}

The present invention relates to a device for testing the durability of the inside handle of the car, and more particularly, the inside handle of the car to determine the durability by automatically performing repeated opening and closing operation for the inside handle of the car door It relates to an endurance test apparatus.

At present, the durability test device for the outside handle of the completed vehicle is provided so that the durability test can be performed from the outside of the vehicle. However, since the conventional durability test device cannot be installed inside the vehicle, this is the inside handle. There is no endurance test for humans, but humans have to test it manually.

However, when the endurance test on the inside handle is not only less reliable, but also repeatedly open and close more than 50,000 times is virtually impossible and inefficient.

Therefore, the durability test could not be performed when the inside handle was assembled in the door, and thus, desired data could not be obtained.

The present invention is conceived in view of such a conventional situation, the present invention is to be installed by adjusting the height at any position in the cabin irrespective of the size of the vehicle, the inside handle by the operation of the cylinder driven by pneumatic or hydraulic An object of the present invention is to provide an inside handle durability test apparatus capable of automatically and repeatedly performing the opening and closing operation.

Features of the present invention for achieving this purpose, the vertically installed female threaded rod 10 and the upper and lower ends of the female threaded rod 10 is screwed and stretched, each having a height adjustment lever 21 up and down The side male screw shaft 20, the disk 30 is rotatably coupled to the end of the upper and lower male screw shaft 20 to be in close contact with the floor and the roof of the vehicle interior, respectively, and one end of the outer peripheral surface of the female screw rod (10) Rotating bar 40 made of a hollow pipe with the other end extending in the horizontal direction while being rotatably connected to the rotating bar, and a sliding bar 50 supported by the tension spring 51 while the rear end is inserted into the inner diameter of the rotating bar 40. And a cylinder 60 fixed horizontally to the tip of the sliding bar 50 and having a connector 80 for connecting the inside handle to the end of the piston 61 and controlled by the drive of the solenoid valve 70. It is composed.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

1 is a schematic view of the inside handle durability test apparatus according to the present invention.

As shown in Figure 1, the female threaded rod 10 has a female thread formed in the inner diameter portion, the male screw shaft 20 is screwed to the upper and lower sides of the female threaded rod 10, respectively, the height of the penetrating through the male screw shaft 20 Length can be adjusted by the adjustment lever 21.

The fixing nut 22 is fastened to the male screw shaft 20 so as to prevent loosening of the screw with the female screw rod 10.

The disc 30 is coupled in a state capable of rotating to the end of the upper and lower male screw shaft 20 is to be fixed by pressing the floor and the roof of the vehicle when installing the subject innovation.

In order to prevent damage to the vehicle body, the disc 30 is preferably made of a flexible material such as rubber or plastic.

Rotating bar 40 is provided with a vertical pipe at one end in the vertical direction and the other end is rotatably coupled to the outer peripheral surface of the female threaded rod 10 in the horizontal direction.

The rotating bar 40 is provided on the female threaded rod (10) and is provided with a fixing ring 41 fixed to the outer peripheral surface of the female threaded rod (10) on both sides of the short pipe so that the height can be adjusted as needed do.

The sliding bar 50 is connected to a tension spring 51 whose one end is fixed at the inner diameter to the rotating part with the rear end inserted into the inner diameter of the rotating bar 40, and the cylinder 60 is connected to the front end of the sliding bar 50. ) Are joined in the same longitudinal direction.

The cylinder 60 is pneumatically connected to the pneumatic circuit so that the piston 61 can repeat the forward and backward motion by the solenoid valve 70, and the piston 61 of the cylinder 60 is connected to the end of the automobile. The connector 80 for connecting an inside handle is provided.

The connector 80 is formed in the shape of a cross section so that it can be fitted to both sides of the inside handle and can be fixed in close contact with the outer surface of the inside handle with a fixing bolt.

Referring to the state of use of the subject innovation in this configuration is as follows.

First, the disc 50 is brought into close contact with the floor and the roof of the vehicle by using the height adjusting lever 21 to fix the apparatus.

That is, when the height adjustment lever 21 is turned, the male screw shaft 20 is extended so that the disc 30 can be tightly fixed to the vehicle body.

Then, tighten the fixing bolt 22 so that the length of the male screw shaft 20 is not reduced by the external force, and using the fixing ring 41 to match the height of the rotating bar 40 to the height of the inside handle.

Then, when the connector 80 is integrally connected to the inside handle, the installation of the device is completed.

In this way, while the solenoid valve 70 is driven in the state where the device is installed, the endurance test of the inside handle may be performed.In parallel with the device, the existing outside handle endurance test device is installed outside the vehicle. It can be used to operate as follows.

When the piston 61 is retracted by the operation of the solenoid valve 70, the locking of the inside handle is released while the tension spring 51 is hardly extended.

At the same time, the sliding bar 50 extends as the tension spring 51 extends as the tension spring 51 overcomes the tensile force by the operation of the outside handle durability test device, and the door is opened. In response to the circular motion of the female threaded rod (10) is to rotate the rotation.

When the door is closed, the door is operated in the reverse order described above, and the operation can be repeatedly performed to test the durability of the inside handle.

As described above, the inside handle durability test apparatus according to the present invention can test the durability of the mechanism related to the inside handle can improve the performance of the inside handle, and can be automatically tested using the equipment Labor can be saved, and there is an advantage that can be installed by adjusting the height at any position in the cabin regardless of the size of the vehicle.
