Description

Technical Field

[0001] This utility model relates to the field of fatigue testing technology for vehicle window glass, specifically a fatigue testing stand for vehicle window glass. Background Technology

[0002] The fatigue testing bench for vehicle windows is used to conduct repeated load and stress cycle tests on vehicle windows, usually to simulate the various dynamic and environmental pressures that the glass is subjected to during actual use.

[0003] The shortcomings of existing technology: Currently, most automotive window fatigue testing benches place the window glass on the test bench with the center of the window glass below the test end, while the two sides of the window glass are above the test bench. If the test bench is not large enough for the window glass, the bottom sides of the window glass will not be supported by the test bench. If the bottom sides of the window glass are not adequately supported, the glass may experience uneven stress distribution during the test. Because the sides of the glass are not effectively supported, these areas may experience greater stress than the center area. This could lead to excessive local stress, increasing the risk of breakage and making it impossible to accurately measure the data of the window glass. Utility Model Content

[0004] The purpose of this invention is to provide a fatigue testing bench for vehicle window glass to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle window glass fatigue testing stand, comprising a main body of the vehicle window glass fatigue testing stand, a testing platform connected to the top of the main body of the vehicle window glass fatigue testing stand, and adjustment mechanisms for supporting the lower sides of the vehicle window glass on both sides of the testing platform. Grooves are provided around the top of each adjustment mechanism, and a protective mechanism for preventing vehicle window glass fragments from shattering on the ground is provided above the grooves. The adjustment mechanism includes: Several bases are fixedly connected to both sides of the test platform; The base has several toothed grooves, and toothed grooves are provided on both sides of the base. A rack rod is engaged with the inside of each toothed groove. Several support platforms are provided. The end of the rack rod near the test platform is fixedly connected to a support platform to support the two sides below the car window glass. The upper side of the support platform is set on the outer surface of the groove.

[0006] Preferably, the protective mechanism includes: Several magnets are arranged inside the groove; A transparent protective shell is fixedly connected above a magnet. A circular groove is provided in the middle of the upper part of the transparent protective shell to facilitate the main body of the vehicle window glass fatigue testing platform to be attached to the upper surface of the vehicle window glass.

[0007] Preferably, the adjustment mechanism further includes: Several connecting rods are fixedly connected to one side of the outer surface of the support platform.

[0008] Preferably, a fixing frame is fixedly connected to the inner side wall of the support platform, and insert rods are fixedly connected to all four sides of the fixing frame.

[0009] Preferably, the test platform has fixing holes around its upper perimeter that are compatible with the insertion rod for fixing the fixing frame above the vehicle window glass and limiting its position.

[0010] Preferably, an anti-slip pad is adhered to the bottom of the fixing frame to increase friction.

[0011] Preferably, a controller is connected to one side of the main body of the vehicle window glass fatigue testing platform via a data cable for controlling the main body of the vehicle window glass fatigue testing platform to adjust the fatigue test values, and a support is provided below the controller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The fatigue testing bench for vehicle window glass has an adjustment mechanism comprising several bases, several toothed grooves, several rack rods, several support platforms, and several connecting rods. Under the action of the toothed grooves, the rack rods are pulled upwards, so that the height of the support platforms is adjusted to be close to the bottom of the vehicle window glass.

[0019] Example 1 Please see Figure 1-5As shown, the present invention provides a technical solution for a vehicle window glass fatigue testing stand: It includes a main body 1 of the vehicle window glass fatigue testing stand, a testing platform 2 connected to the top of the main body 1, and adjustment mechanisms 3 for supporting the lower sides of the vehicle window glass on both sides of the testing platform 2. Grooves 4 are provided around the top of each adjustment mechanism 3, and a protective mechanism 5 is provided above the grooves 4 to prevent vehicle window glass fragments from shattering on the ground. The adjustment mechanism 3 includes several bases 301, several toothed grooves 302, several racks 303, and several support platforms 304. The bases 301 are fixedly connected to the testing stand. On both sides of the test platform 2, the base 301 has grooves 302. A rack rod 303 is engaged inside the grooves 302. A support platform 304 is fixedly connected to one end of the rack rod 303 near the test platform 2 to support the lower sides of the car window glass. The upper side of the support platform 304 is set on the outer surface of the groove 4.

When using the vehicle window fatigue testing platform 1 to test the vehicle window glass, the magnets 501 are placed inside the groove 4 and magnetically fixed to the support platform 304, so that the transparent protective shell 502 covers the testing end of the vehicle window fatigue testing platform 1. This helps to cover the testing end of the vehicle window fatigue testing platform 1, avoids the vehicle window glass from breaking during testing, and prevents fragments from injuring the staff, thus improving practicality.

[0021] Adjustment mechanism 3 also includes: Several connecting rods 305 are fixedly connected to one side of the outer surface of the support platform 304.

[0022] A fixing frame 6 is fixedly connected to the inner wall of the support platform 304, and insert rods 7 are fixedly connected to all four sides of the fixing frame 6.

[0023] The test platform 2 has fixing holes around its upper perimeter that are compatible with the insertion rod 7 for fixing the fixing frame 6 above the car window glass and limiting its position.

[0024] An anti-slip pad 8 is glued to the bottom of the fixing frame 6 to increase friction.

[0025] A controller 9 is connected to one side of the main body 1 of the vehicle window glass fatigue testing bench via a data cable to control the adjustment of fatigue test values. A support 10 is provided below the controller 9.

[0026] In this device, the car window glass is placed on the test platform 2. When testing the car window glass using the main body 1 of the car window glass fatigue testing platform, the magnet 501 is placed inside the groove 4 and magnetically fixed to the support platform 304, so that the transparent protective shell 502 covers the test end of the main body 1 of the car window glass fatigue testing platform. Under the action of the toothed groove 302, the rack rod 303 is pulled upward, and the connecting rod 305 can synchronize the height of the support platform 304, so that the height of the support platform 304 is adjusted to be close to the bottom of the car window glass. Then, the parameters can be adjusted by the controller 9 to control the main body 1 of the car window glass fatigue testing platform to perform fatigue pressure testing on the car window glass.
