Description

Technical Field

[0001] This utility model relates to the field of seat belt testing technology, and in particular to a device for testing the toughness performance of automotive seat belts. Background Technology

[0002] Car seat belts are an indispensable part of automobiles. They are safety devices designed to restrain occupants during a collision and to prevent them from secondary collisions with the steering wheel and dashboard, or from being ejected from the vehicle during a collision, thus preventing injury or death. Car seat belts are also known as seat belts and are a type of occupant restraint device. Before being manufactured, seat belts need to undergo toughness testing to prevent them from breaking under the tensile force of a large impact after being put into use.

[0003] A search revealed that the document with publication number "CN222299144U" mentions "a device for testing the toughness of automotive seat belts, relating to the technical field of automotive parts testing devices. It includes a workbench with auxiliary grooves on both the front and rear sides of its surface, a guide groove in the center of the upper part of the workbench surface, and support plates fixedly installed at both ends of the guide groove on the upper part of the workbench surface. A fixing mechanism is installed on the opposite side of the support plate surface." During use, the device, through the fixing mechanism, base plate, holes, grooves, rotating rod, pressure plate, and locking teeth, can conveniently and effectively fix the seat belt. Even during the toughness test, when the seat belt is tensioned, the device ensures the firmness of both ends of the seat belt, preventing it from loosening and improving the stability of the seat belt during the test.

[0004] However, using locking teeth to tighten seat belts can easily damage them. In addition, existing devices are mostly tested at room temperature, which cannot simulate the actual use of seat belts in different temperature environments, and can easily lead to discrepancies between test results and actual use.

[0005] Therefore, we provide a device for testing the toughness of automotive seat belts to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a device for testing the toughness performance of automotive seat belts, aiming to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A device for testing the toughness performance of automotive seat belts includes a testing platform. Toughness testing components are arranged on both sides of the testing platform. Each toughness testing component includes a mounting bracket installed at the right end of the testing platform, with a winding rod arranged inside the mounting bracket. A connecting platform is arranged at the left end of the testing platform, with a fixing rod arranged outside the connecting platform. A seat belt is connected between the fixing rod and the winding rod. A temperature simulation component is arranged inside the testing platform, including an electric heating box installed at the rear end of the testing platform. A heating air inlet is provided on the inner wall of the testing platform.

[0009] Optionally, the winding rod and the mounting frame are rotatably connected. The winding rod is arranged in two symmetrical halves. A drive motor is installed at the rear end of the mounting frame. The winding rod is connected to the output shaft of the drive motor.

[0010] Optionally, a connection slot is provided at the right end of the connecting platform, and connecting blocks are welded to both ends of the fixing rod. Each connecting block is provided with a connecting pin at its left end. The connecting pin and the connection slot are connected by a slot. A pressure sensor can be installed inside the connection slot. The fixing rod has a through groove in the middle.

[0011] Optionally, a blower is installed at the rear end of the electric heating box, and the electric heating box is connected to the heating air inlet by a pipe.

[0012] Optionally, a protective top cover is connected to the top of the testing station via a pin, and tempered glass is installed on the inner side of the protective top cover.

[0013] Optionally, an electric control screw is installed at the bottom inner side of the testing platform, and a connecting slider is threadedly connected to the top of the electric control screw. A testing camera is installed at the top of the connecting slider, and the testing camera is positioned directly below the safety belt.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a toughness testing component, the drive motor rotates the winding rod, allowing for the winding and unwinding of the seat belt, thus testing its toughness performance. Simultaneously, the connection between the connecting slot and the connecting pin's slot facilitates the installation and removal of the fixing rod. A pressure sensor can also be installed inside the connecting slot to monitor the stress on the seat belt during the stretching process in real time, further improving the accuracy and reliability of the test. Furthermore, the winding method utilizes the seat belt's own friction to increase stability during the stretching process, preventing the seat belt from slipping off.

[0016] 2. By setting up a temperature simulation component, and using an electric heating box and a blower in conjunction, air of different temperatures can be supplied into the testing platform to simulate the use of seat belts in different temperature environments. This allows for the testing of the toughness performance of seat belts at different temperatures, improving the practicality and reliability of the test. At the same time, a camera records the morphological changes of the seat belt during the tensile test in real time, facilitating subsequent data analysis and processing. Furthermore, the addition of a protective top cover and tempered glass allows operators to clearly observe the testing process while ensuring their safety. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4As shown, this utility model provides a technical solution: a device for testing the toughness performance of automotive seat belts, including a testing platform 1, with toughness testing components 2 arranged on both sides of the testing platform 1. The toughness testing components 2 include a mounting bracket 201 installed on the right end of the testing platform 1, a winding rod 202 arranged on the inner side of the mounting bracket 201, a connecting platform 204 arranged on the left end of the testing platform 1, a fixing rod 206 arranged on the outer side of the connecting platform 204, and a seat belt 209 connected between the fixing rod 206 and the winding rod 202. A temperature simulation component 3 is arranged on the inner side of the testing platform 1, and the temperature simulation component 3 includes an electric heating box 301 installed at the rear end of the testing platform 1. A heating air inlet 303 is opened on the inner wall of the testing platform 1.

[0024] Furthermore, the winding rod 202 and the mounting frame 201 are rotatably connected. The winding rod 202 is arranged in two symmetrical halves. The rear end of the mounting frame 201 is equipped with a drive motor 203. The winding rod 202 is connected to the output shaft of the drive motor 203. The end of the safety belt 209 is inserted into the middle of the winding rod 202, and then the safety belt 209 is wrapped around the winding rod 202. The drive motor 203 drives the safety belt 209 to wind up, thereby performing a tensile test.

[0025] Furthermore, a blower 302 is installed at the rear end of the electric heating box 301. The electric heating box 301 is connected to the heating air inlet 303 by a pipe. The blower 302 blows outside air into the electric heating box 301 for heating. The heated air enters the test bench 1 through the pipe, thereby conducting a temperature simulation test on the safety belt 209 in the test bench 1 to test the toughness performance of the safety belt 209 under different temperature environments and improve the comprehensiveness of the test.

[0026] Furthermore, a connecting slot 205 is provided at the right end of the connecting platform 204, and connecting blocks 207 are welded to both ends of the fixing rod 206. Connecting pins 208 are provided at the left ends of each connecting block 207. The connecting pins 208 and the connecting slot 205 are connected by a slot. A pressure sensor can be installed inside the connecting slot 205. A through slot is provided in the middle of the fixing rod 206. The other end of the safety belt 209 is passed through the through slot of the fixing rod 206, and the safety belt 209 is wrapped around the fixing rod 206. Then, the fixing... The fixed rod 206 is fixed by engaging the connecting pin 208 on the connecting block 207 into the connecting slot 205 on the connecting platform 204. Thus, when the drive motor 203 drives the winding rod 202 to rotate and perform a tensile test on the seat belt 209, the fixed rod 206 can provide a stable tension on the seat belt 209, ensuring the accuracy of the test results. At the same time, the pressure sensor that can be installed inside the connecting slot 205 can monitor the tension on the fixed rod 206 in real time, further ensuring the accuracy and safety of the test.

[0027] Furthermore, an electric control screw 306 is installed on the inner bottom of the testing platform 1. A connecting slider 307 is threaded onto the upper part of the electric control screw 306, and a detection camera 308 is installed on the top of the connecting slider 307. The detection camera 308 is positioned directly below the safety belt 209. By setting the detection camera 308, the morphological changes of the safety belt 209 during the tensile test can be recorded in real time, facilitating subsequent analysis and processing of test data and improving the accuracy and reliability of the test. At the same time, driven by the electric control screw 306, the connecting slider 307 can be moved on the electric control screw 306, thereby moving the detection camera 308 to capture and record images of different positions of the safety belt 209, increasing the comprehensiveness of the test.

[0028] Furthermore, a protective top cover 304 is connected to the top of the testing platform 1 via a pin. Tempered glass 305 is installed on the inner side of the protective top cover 304. The protective top cover 304 effectively prevents fragments or splashes generated during the toughness test of the safety belt 209 from injuring the operator, thus improving the safety of the test process. At the same time, the tempered glass 305 not only allows the operator to clearly observe the situation during the test, but also has good impact resistance, further ensuring the safety of the operator.

[0029] Working Principle: The device is installed in the working position and powered by an external power source. The first end of the safety belt 209 is then inserted into the middle of the winding rod 202, wrapping the safety belt 209 around it. The other end of the safety belt 209 is passed through the through slot of the fixing rod 206 and wrapped around it. The fixing rod 206 is then secured by inserting the connecting pin 208 on the connecting block 207 into the connecting slot 205 on the connecting platform 204. At this point, the drive motor 203 is started, and its output shaft rotates the winding rod 202, performing a tensile test on the safety belt 209. Simultaneously, a pressure sensor installed inside the connecting slot 205 monitors the tension on the fixing rod 206 in real time and transmits the data to an external controller for recording and analysis by the operator. Simultaneously, the blower 302 is started, blowing outside air into the electric heating chamber 3. Heating is performed in step 01, and the heated air enters the testing platform 1 through a pipe to conduct a temperature simulation test on the seat belt 209 inside the testing platform 1. This test examines the toughness performance of the seat belt 209 under different temperature environments, improving the comprehensiveness of the test. During the test, the operator can clearly observe the test process through the tempered glass 305 installed inside the protective top cover 304. At the same time, the detection camera 308 records the morphological changes of the seat belt 209 in real time during the tensile test. Driven by the electric control screw 306, the connecting slider 307 moves on the electric control screw 306, which in turn moves the detection camera 308 to capture and record images of different positions of the seat belt 209, increasing the comprehensiveness of the test. After the test is completed, the drive motor 203 and the blower 302 are turned off, the device is reset, and the test is completed. This completes the use of an automotive seat belt toughness performance testing device.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
