Description

Technical Field

[0001] This utility model relates to the field of glass testing equipment technology, specifically a device for testing the hardness of automotive windshields. Background Technology

[0002] The windshield of a car is a transparent glass installed at the front of the car. Its main function is to protect the driver and passengers from external factors such as wind, rain, and flying insects, and to provide a clear view. After the windshield is manufactured, it needs to be tested using a hardness testing device.

[0003] Some automotive windshield hardness testing devices have also appeared in the prior art. For example, a Chinese patent with application number 202520416551.X discloses an automotive windshield hardness testing device, including: a hardness testing component, which includes a base and a support frame; and an auxiliary limiting component, which includes a guide rail, a slider, a fixing ring, a connecting rod, and a limiting frame. The guide rail is fixed to the top of the base on both sides, the slider is slidably connected to the surface of the guide rail, the fixing ring is fixed to the outer side of the slider, the connecting rod is located at one end outside the fixing ring, and the limiting frame is fixed to the opposite end of the connecting rod.

[0004] While this technical solution can control the flying debris within a certain range, thereby reducing the amount of debris flying outward and preventing injury to nearby personnel, the position of the testing hammer in this type of hardness testing device is fixed. The testing position on the car windshield and the force of the hammer strike cannot be adjusted according to usage needs, limiting its practicality in dust reduction. Furthermore, after each use, the testing hammer needs to be manually lifted back to its initial position for reinstallation, making it inconvenient to use. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1-9In this embodiment of the present invention, a windshield hardness testing device includes: a support frame 100 and a testing mechanism 200. A collection shell 110 is fixedly connected to the support frame 100, and a rectangular hole 112 is provided on the collection shell 110.

By opening the rotating door 111, the glass fragments can be easily removed and cleaned.

[0040] Example 1

[0041] like Figure 2-9As shown, in this embodiment, the supporting component includes a supporting plate 130, which is disposed on the top of the inner side of the collection shell 110. The detection mechanism 200 includes a connecting plate 210, a detection hammer 220, and a winding reel 250. The connecting plate 210 is disposed on the top of the collection shell 110, and an adjustment component is disposed on the outer side of the connecting plate 210. Multiple height adjustment components are disposed on the outer side of the adjustment component. The detection hammer 220 is disposed at the bottom of the connecting plate 210. The winding reel 250 is rotatably connected to an inner sidewall of the connecting plate 210. A winding rope 251 is wound and fixed inside the winding reel 250, and the bottom of the winding rope 251 passes through the connecting plate 210 and is fixedly connected to the detection hammer 220. The upper part is equipped with a winding assembly, which includes a stepper motor 260 and an air pump 270. The stepper motor 260 is fixedly connected to the connecting plate 210. The output end of the stepper motor 260 passes through the side wall of the connecting plate 210 and is fixedly connected to a circular block 261. The circular block 261 is located inside the winding reel 250. The circular block 261 has an air extraction hole 262 and multiple storage slots 263. The air extraction hole 262 communicates with the multiple storage slots 263. Each of the multiple storage slots 263 has a locking block 265 slidably connected inside. Each locking block 265 is fixedly connected to the inner side wall of the corresponding storage slot 263 with multiple compression springs 266. The multiple locking blocks 265 are respectively engaged with the corresponding locking slots 252. The air pump 270... The air pump 270 is fixedly connected to the connecting plate 210. A connecting pipe 271 is fixedly connected to the suction end of the air pump 270, and one end of the connecting pipe 271 is rotatably connected to the round block 261. The connecting pipe 271 is connected to the suction port 262, and an electric control valve 272 is fixedly connected to the connecting pipe 271. The adjustment assembly includes: a fixed frame 230, a movable housing 280, and a stepper motor 290. The fixed frame 230 is located outside the connecting plate 210. The movable housing 280 is slidably connected to the fixed frame 230. A stepper motor 281 is fixedly connected inside the movable housing 280, and a screw 282 is fixedly connected to the output end of the stepper motor 281. One end of the screw 282 is rotatably connected to the movable housing 280. 2. A movable block 283 is screwed onto the upper part of the frame and is fixed to the connecting plate 210. A stepper motor 290 is fixed to the fixed frame 230. The output end of the stepper motor 290 passes through the side wall of the fixed frame 230 and is fixed to a screw 291. The stepper motor 290 is rotatably connected to the fixed frame 230. A movable block 292 is screwed onto the screw 291 and is fixed to the movable shell 280. The height adjustment component includes a cylinder 240. An angle iron 241 is fixed to the cylinder 240 and is fixed to the collecting shell 110. An angle iron 242 is fixed to the output end of the cylinder 240 and is fixed to the fixed frame 230.

[0042] In this embodiment, the support plate 130 is used to support the car windshield. Multiple cylinders 240 are activated to move the adjustment assembly, connecting plate 210, detection hammer 220, winding reel 250, and winding assembly to an appropriate height. Stepper motor 290 is activated to rotate screw 291, thereby moving moving block 292 and moving housing 280 to the appropriate position. Stepper motor 281 is then activated to rotate screw 282, thereby moving moving block 283, connecting plate 210, detection hammer 220, and winding reel 250 to the appropriate position. The device is moved to a suitable position, and the air pump 270 is activated to evacuate air from the connecting pipe 271. This facilitates the evacuation of air from the evacuation port 262 and the multiple storage slots 263, causing the multiple locking blocks 265 to move into the multiple storage slots 263. Consequently, the multiple locking blocks 265 separate from the multiple storage slots 263. Under the action of its own weight, the detection hammer 220 falls downwards, and the winding reel 250 rotates, releasing the winding rope 251. The falling detection hammer 220 impacts the car windshield below, thereby testing the hardness of the car windshield. After the inspection is completed, the air pump 270 is turned off and the electronic control valve 272 is turned on, allowing air to enter the connecting pipe 271, the air extraction port 262, and the multiple storage slots 263. Under the action of the compression spring 266, the locking block 265 begins to reset. Then, the stepper motor 260 is started to rotate forward, causing the circular block 261 to rotate forward and the multiple locking blocks 265 to move. When the locking block 265 moves to the slot 252, the compression spring 266 pushes the locking block 265 to insert into the corresponding slot 252. After the locking block 265 is inserted into the slot 252, the take-up reel 250 rotates, facilitating the... The winding rope 251 is wound up, causing the testing hammer 220 to rise and reset, making it easier to use the testing mechanism 200 again. This makes it simpler and more convenient to use and reduces the labor intensity of the staff. When the testing mechanism 200 is working, the horizontal position of the testing hammer 220 can be adjusted to adjust the testing position of the car windshield, and the height of the testing hammer 220 can be adjusted to adjust the impact force of the testing mechanism 200 on the car windshield during testing. This allows the testing mechanism 200 to meet the testing needs of car windshields of different specifications, improving the practicality of the car windshield hardness testing device.

[0043] Example 2

[0044] Based on Example 1, in order to facilitate the collection of broken car windshields after testing.

[0045] like Figure 2As shown, in this embodiment, the supporting component includes a supporting plate 130, which is rotatably connected to the collecting shell 110. A stepper motor 131 is provided at one end of the supporting plate 130 and is fixedly connected to the collecting shell 110. The supporting component includes a rectangular shell 140, which is fixedly connected to the collecting shell 110. Multiple cylinders 141 are fixedly connected inside the rectangular shell 140. A rectangular plate 142 is provided on the rectangular shell 140, and the output ends of the multiple cylinders 141 are all fixedly connected to the rectangular plate 142. The rectangular plate 142 is slidably connected to the rectangular hole 112, and the top of the rectangular plate 142 contacts the bottom of the supporting plate 130.

[0046] In practice, multiple cylinders 141 are activated to extend the rectangular plate 142, which in turn moves the rectangular plate 142 to contact the bottom of the support plate 130. This provides auxiliary support for the horizontal support plate 130, ensuring the service life of the support plate 130 and the stepper motor 131. After the test, the cylinders 141 are activated to retract the rectangular plate 142, which then returns to its original position. The stepper motor 131 is then activated to deflect the support plate 130, making it easier to pour the broken windshield glass from the top of the support plate 130 into the collection shell 110. This improves the cleaning efficiency of the broken windshield glass and facilitates its reuse in the windshield hardness testing device. Furthermore, the collection shell 110 makes it convenient to collect the broken windshield glass, making it more easy to use.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
