Description
Technical Field
[0001] The utility model relates to the technical field of sun visor performance testing, in particular to a device for testing the plugging and unplugging durability of a sun visor hook. Background Art
[0002] The sun visor is an important part of the car interior. It is fixedly installed in the front and upper part of the driver's seat and the co-pilot seat to block the sunlight in front or on the side. Generally speaking, the top of the sun visor is kept fixed by a fixed support and a hook, wherein the fixed support always fixes the sun visor, but the hook and the sun visor can be plugged in and out. When it is necessary to block the sunlight from the side, the sun visor needs to be pulled out from the hook, and then the entire sun visor is rotated around the fixed support to the window position to block the sunlight from the side. After use, rotate it in the opposite direction around the fixed support, and then insert the sun visor into the hook to increase the placement stability of the sun visor. Since the hook and the sun visor can be repeatedly plugged in and out, the plug-in durability of the hook of the sun visor must be measured before it leaves the factory. However, at present, there are few relevant testing equipment on the market. Utility Model Content
[0003] The purpose of the utility model is to overcome the defects of the above-mentioned prior art and to provide a device for testing the plugging and pulling durability of the sun visor hook.
[0004] In order to achieve the purpose of the utility model, the present application provides the following technical solutions.
[0005] In the first aspect, the present application provides a device for testing the plug-in and pull-out durability of a sun visor hook, wherein the sun visor comprises a sun visor body, a fixed support and a hook, wherein the fixed support is fixed to the sun visor body, a connecting shaft is provided on the top of the sun visor body, and the connecting shaft is plug-in connected in the hook, the device comprises a base, a fixing frame fixed on the base, a driving unit and a pressure detection unit, the fixing frame is provided with two fixing seats, wherein a fixed support of the sun visor to be tested is fixed at the bottom of one of the fixing seats, and a hook of the sun visor to be tested is fixed at the bottom of the other fixing seat, the driving unit comprises a cylinder and a claw fixed to the cylinder, and during testing, the claw is sleeved on the connecting shaft, and the pressure detection unit is installed at the connection between the cylinder and the claw. The fixed support and hook are installed using a fixing frame to simulate the installation state of the sun visor in actual application. Then the claws are driven by the cylinder to repeatedly push and pull the connecting shaft in small amplitudes, so that the connecting shaft is continuously pulled out and then inserted into the hook. The pressure sensor is used to detect the force applied to the connecting shaft at the moment of pulling out and inserting, so as to judge the plug-in and pull-out durability of the hook.
[0006] In an implementation of the first aspect, the cylinder is arranged obliquely, and a movement direction of the cylinder is the same as an opening direction of the hook.
[0007] In an implementation manner of the first aspect, the driving unit includes a support frame, a bottom plate is provided with a positioning hole, and the support frame is fixed to the positioning hole by bolts.
[0008] In one embodiment of the first aspect, the support frame is provided with a lifting groove, and support rods are provided on both sides of the cylinder, and the support rods are slidably connected in the lifting grooves and are fixed by fastening screws. Since the opening angles of the hooks of different models of sun visors are different, to ensure the accuracy of the test results, it is necessary to try to ensure that the connecting shaft can be pulled out or inserted directly into the opening of the hook to avoid the side wall of the hook from hindering the connecting shaft. In the present application, the cylinder is fixed by the support rod and the fastening screw, so the cylinder can be adjusted to a certain angle around the support rod, and can also be raised and lowered in the vertical direction; at the same time, through the setting of the support frame and the positioning hole, it can also be translated in the horizontal direction. Therefore, according to the hook structure of the specific sun visor to be tested, the angle and position of the cylinder can be adjusted so that its fixed claw matches the hook, including the claw position, the claw movement trajectory, etc., so as to ensure the accuracy of the test.
[0009] In one implementation of the first aspect, the claw includes a hard linear rod and a pull ring integrally fixed to the top end of the linear rod, the pull ring is sleeved on the connecting shaft, and the bottom of the linear rod is connected to the cylinder via a pressure sensor.
[0010] In one implementation of the first aspect, the fixing frame is provided with two groups of fixing seats, each group of fixing seats is fixed to a fixing support and a hook of a sun visor to be tested, and a clamping claw is fixed to each side of the cylinder, each clamping claw is connected to a connecting shaft of a sun visor to be tested. This arrangement can drive two clamping claws with one cylinder at the same time, that is, two sun visors can be tested at the same time, thereby improving the test efficiency.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] (1) By simulating the plug-in and pull-out status of the connecting shaft and the hook during actual use, and using a pressure sensor to detect the force exerted on the connecting shaft at the moment of pull-out and insert-out, the plug-in and pull-out durability of the hook can be determined, and the test structure is accurate;
[0013] (2) The plug-in and pull-out durability of the hooks of two sun visors can be tested simultaneously, with high testing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
