Description

Technical Field

[0001] The present application relates to the technical field of vehicle strength testing, and in particular to a strength testing tool. Background Art

[0002] In the field of vehicle strength testing, seat strength and the strength of seat-to-body fastenings are directly related to passenger safety. As industry safety standards continue to improve, accurately simulating mechanical properties under crash conditions has become a key technical challenge.

[0003] Currently, the industry generally adopts a technical solution that involves cutting the body, matching the frame, and connecting it to a test slide. This solution requires cutting the body, then installing it through holes in a customized frame and test slide to establish a mechanical transmission path for seat strength testing. For example, two bus models, one with 20 seats and the other with 22 seats, can be cut into 13 different body types, requiring a corresponding number of custom frames during testing.

[0004] However, this approach had significant drawbacks. First, customizing the frame for each cut vehicle body significantly increased testing costs. Second, the frame was bulky and difficult to move, and required extremely high precision in matching the slide holes. Repeated debugging resulted in lengthy installation times, severely impacting test efficiency. Summary of the Invention

[0005] The purpose of the present application is to provide a strength test tool to solve the problems of high test cost and low test efficiency in existing vehicle strength testing technologies. The strength test tool of the present application can flexibly adapt to the strength test requirements of seats and their fixings of various different models by designing multiple splicable tool modules. The design of the tool module makes the entire test tool light in weight and easy to disassemble and assemble, thereby effectively replacing the traditional customized frame and reducing the test cost. At the same time, the splicing method of the tool module simplifies the installation process and improves the test efficiency. Through the strength test tool of the present application, the mechanical properties under collision conditions can be accurately simulated, providing an efficient and economical solution for the field of vehicle strength performance testing.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] An embodiment of the present application provides a strength test fixture for testing the strength of seats and their mountings on various vehicles. Each vehicle body includes multiple crossbeams arranged sequentially from the front to the rear. The modules consisting of the vehicle bodies and seats connected thereto are divided into multiple different test modules, each of which includes at least one crossbeam. The strength test fixture includes multiple fixture modules; at least two of the multiple fixture modules can be spliced ​​together to form multiple different splicing modules, each of which is used to connect the crossbeams of the multiple test modules to a sliding test platform.

[0008] This embodiment realizes modularization by designing the strength test tooling into multiple tooling modules, at least two of which are spliced ​​together to form a variety of different splicing modules to respectively adapt to the support of multiple test modules on the sliding test platform. First, the modules consisting of the vehicle body and seats are divided into standardized test modules containing crossbeams, which avoids the need to customize the frame for each model, thereby reducing the design workload and material consumption, and significantly reducing the production cost. Secondly, by utilizing multiple splicable tooling modules, the test modules corresponding to the model are flexibly combined to quickly build a test platform. Its light and easy-to-assemble and disassemble characteristics greatly shorten the installation and debugging time compared to traditional frames, and significantly improve the test efficiency. In addition, a set of tooling can be adapted to the testing of multiple models through different splicing methods, which enhances versatility, reduces resource waste, and further reduces the test cost.

[0009] In a possible implementation, the number of tooling modules is less than the number of testing modules.

[0010] While ensuring compatibility with various vehicle seat strength tests, this embodiment reduces the number of tooling modules, lowering tooling production costs, management costs, and complexity. It also facilitates assembly and disassembly, shortens installation and commissioning time, further improves test efficiency, and enhances the practicality and cost-effectiveness of the strength test tooling.

[0011] In a possible implementation, the number of tooling modules is set to 8 and the number of test modules is set to 13.

[0012] This embodiment is designed for the strength test of the entire vehicle seat and its fixings of a certain model. The strength test of this model covers 22 seat combinations, and 13 cut-out bodies are required for seat installation. According to the traditional method, 13 cut-out bodies need to be equipped with 13 special frames to connect with the test slide. However, through innovative design, this solution can replace 13 special frames with only 8 tooling modules to complete the strength test in conjunction with the test modules. Such a design not only ensures that a variety of test requirements can be met with a minimum of tooling modules, greatly reducing production costs; but also because the number of modules is reduced, the tooling is lighter, disassembly and assembly are more convenient, and the installation and debugging time is significantly shortened, which effectively improves the test efficiency and achieves cost reduction and efficiency improvement of seat strength testing.

[0014] In this embodiment, the first tooling module can be spliced ​​with the second tooling module to form a first splicing module, which is used to connect the first test module to the sliding test platform. This sophisticated module division and connection relationship ensures that the mechanical loads exerted on the seat and its fixings are accurately transmitted to the sliding test platform along a preset path during testing, effectively avoiding testing errors caused by unstable or inaccurate connections, thereby significantly improving test accuracy and reliability. Through a modular splicing design, a limited number of tooling modules can be used to adapt to different test modules, reducing the number of tooling units produced, lowering costs such as steel procurement and processing, and avoiding rework waste caused by unreasonable designs. Clear module connection rules enable operators to quickly select the appropriate tooling module for splicing and assembly, eliminating the complex debugging and installation required by traditional solutions, significantly reducing installation and debugging time. The standardized connection method allows operators to quickly grasp the key operating points, reduce errors, and further ensure the efficient progress of the test process, thereby achieving the goals of reducing testing costs and improving testing efficiency.

[0079] Through the above-mentioned modular segmentation method, complex vehicle testing is simplified to testing of standardized modules, avoiding the need to customize a complete frame for each model. This effectively reduces the workload and material consumption at the design source and significantly reduces production costs.

[0080] In the above embodiment, each vehicle body includes multiple crossbeams arranged sequentially from the front to the rear of the vehicle. For example, the vehicle body may include eight crossbeams, which may be a first crossbeam, a second crossbeam, a third crossbeam, a fourth crossbeam, a fifth crossbeam, a sixth crossbeam, a seventh crossbeam, and an eighth crossbeam, arranged sequentially from the front to the rear of the vehicle. Each test module includes at least one crossbeam. The crossbeams are used to ensure the structural strength of the vehicle body and to connect the vehicle body to the test platform.

[0081] The strength test tooling may include multiple tooling modules, at least two of which can be spliced ​​together to form a variety of different splicing modules. The multiple splicing modules are respectively used to connect the beams of multiple test modules to the sliding test platform to achieve strength testing.

[0082] This embodiment realizes modularization by designing the strength test tooling into multiple tooling modules, at least two of which are spliced ​​together to form a variety of different splicing modules to respectively adapt to the support of multiple test modules on the sliding test platform. First, the modules consisting of the vehicle body and seats are divided into standardized test modules containing crossbeams, which avoids the need to customize the frame for each model, thereby reducing the design workload and material consumption, and significantly reducing the production cost. Secondly, by utilizing multiple splicable tooling modules, the test modules corresponding to the model are flexibly combined to quickly build a test platform. Its light and easy-to-assemble and disassemble characteristics greatly shorten the installation and debugging time compared to traditional frames, and significantly improve the test efficiency. In addition, a set of tooling can be adapted to the testing of multiple models through different splicing methods, which enhances versatility, reduces resource waste, and further reduces the test cost.

[0083] In some embodiments, the number of tooling modules can be fewer than the number of test modules. This reduces the number of tooling modules, lowering tooling production costs, management costs, and complexity, while ensuring compatibility with various vehicle seat strength tests. This also facilitates assembly and disassembly, shortens installation and commissioning time, further improves testing efficiency, and enhances the practicality and cost-effectiveness of the strength test tooling. Of course, in other implementations, the number of tooling modules can be greater than or equal to the number of test modules.

[0084] Optionally, the number of tooling modules is set to 8 and the number of test modules is set to 13. This configuration is designed specifically for strength testing of the entire vehicle's seats and their fixings. The test covers 22 seat combinations, requiring 13 cut-out bodies for seat installation. Traditionally, the 13 cut-out bodies would need to be equipped with 13 dedicated frames to connect to the test slide. However, through innovative design, this solution uses only 8 tooling modules to replace the 13 dedicated frames, which are then used in conjunction with the test modules to complete the strength test. This design not only ensures that a minimum of tooling modules are used to meet various test requirements, significantly reducing production costs; but also, due to the reduction in the number of modules, the tooling is lighter, and disassembly and assembly are more convenient, significantly shortening installation and debugging time, effectively improving test efficiency, and achieving cost reduction and efficiency improvement in seat strength testing. Of course, in some other implementations, the number of tooling modules and the number of test modules can be flexibly adjusted according to actual needs to adapt to the testing needs of different vehicle models and seat combinations.

[0085] In some embodiments, the plurality of test modules include a first test module (ie, Figure 1 - Figure 3 The vehicle body of the first test module includes a first cross beam, a second cross beam, a third cross beam, a fourth cross beam, and a fifth cross beam.

[0086] The multiple tooling modules include a first tooling module 1 and a second tooling module 2. Figure 14 and Figure 15 , Figure 14 This is a structural diagram of the first tooling module 1 in the strength test tooling provided in some embodiments of the present application. Figure 15 The present invention provides a schematic structural diagram of the second tooling module 2 in the strength test tooling provided in some embodiments of the present application. The first tooling module 1 is suitable for connecting the first crossbeam to the sliding test platform. Specifically, the first tooling module 1 may include a support assembly 11, and the support assembly 11 is used to connect to the first crossbeam. The second tooling module 2 is suitable for connecting the second crossbeam, the third crossbeam, the fourth crossbeam and the fifth crossbeam to the sliding test platform. Specifically, the second tooling module 2 includes a support assembly 21, a support assembly 22, a support assembly 23 and a support assembly 24. The support assembly 21, the support assembly 22, the support assembly 23 and the support assembly 24 are used to connect to the second crossbeam, the third crossbeam, the fourth crossbeam and the fifth crossbeam, respectively.

[0087] The first tooling module 1 can be spliced ​​with the second tooling module 2 to form a first splicing module. Figure 16 , Figure 16 This is a structural diagram of the first splicing module in the strength test tool provided in some embodiments of the present application, wherein the first splicing module is used to connect the first test module to the sliding test platform. Figure 17 , Figure 17 The first test module is connected to Figure 16 The structural diagram of the first splicing module is shown.

[0088] In this embodiment, the first tooling module 1 can be spliced ​​with the second tooling module 2 to form a first splicing module, which is used to connect the first test module to the sliding test platform. This sophisticated module division and connection ensures that the mechanical loads acting on the seat and its fixings are accurately transmitted to the sliding test platform along a predetermined path during testing, effectively avoiding testing errors caused by unstable or inaccurate connections, thereby significantly improving test accuracy and reliability. Through a modular splicing design, a limited number of tooling modules can be used to adapt to different test modules, reducing the number of tooling units required, lowering costs such as steel procurement and processing, and avoiding rework waste caused by inappropriate designs. Clear module connection rules enable operators to quickly select the appropriate tooling module for splicing and assembly, eliminating the complex debugging and installation required by traditional solutions, significantly reducing installation and debugging time. The standardized connection method allows operators to quickly grasp the key operating points, reduce errors, and further ensure the efficient progress of the testing process, thereby achieving the goals of reducing testing costs and improving testing efficiency.

[0089] In some embodiments, the plurality of test modules further includes a second test module (i.e. Figure 4 - Figure 6 The vehicle body of the second test module includes the second cross member, the third cross member, the fourth cross member, the fifth cross member and the sixth cross member.

[0090] The plurality of tooling modules also includes a third tooling module 3, see Figure 18 , Figure 18 This is a schematic diagram of the structure of the third tooling module 3 in the strength test tooling provided in some embodiments of the present application. The third tooling module 3 is suitable for connecting the sixth crossbeam to the sliding test platform. Specifically, the third tooling module 3 may include a support assembly 31, which is used to connect to the sixth crossbeam. The support assembly 31 is used to connect to the sixth crossbeam.

[0102] In some embodiments, the tooling module is made of steel, and the material of the steel is Q235.

[0103] See also Figure 31 and Figure 32In this embodiment, Q235 steel, with its excellent comprehensive mechanical properties and cost-effectiveness, not only ensures the tooling possesses sufficient strength and stability to meet the mechanical transmission requirements of seat strength testing, but also significantly reduces material costs compared to high-performance steels. Furthermore, Q235 steel exhibits excellent processability, making it easy to cut and weld. This helps reduce processing steps and time, improving tooling production efficiency, and ultimately reducing costs and increasing efficiency while ensuring performance.

[0104] In the above embodiment, the optional steel specifications include the following four types: C-shaped steel with a cross-sectional size of 120mm×53mm and a thickness of 5.5mm; C-shaped steel with a cross-sectional size of 95mm×50mm and a thickness of 5mm; C-shaped steel with a cross-sectional size of 80mm×43mm and a thickness of 5.3mm; and flat steel with a plate thickness of 15mm. However, there is not only one steel specification, and steels of different specifications have different strengths and rigidities. The selection of these specific steel specifications is intended to ensure that the tooling module can meet the requirements of the strength test while maintaining appropriate weight and cost-effectiveness. Due to its unique cross-sectional shape, C-shaped steel has excellent bending strength and load-bearing capacity, making it suitable for tooling parts that bear large loads. Flat steel provides a flat and stable connection surface, which is convenient for connection and fixation with other components. During the tooling design and manufacturing process, through the reasonable selection and matching of steel specifications, the strength and rigidity of the tooling can be precisely controlled, thereby ensuring that the tooling can exhibit excellent performance under various test conditions.

[0105] Optionally, Q235 steel can be replaced with other steels with similar mechanical properties and economy, such as Q345 steel, which has higher strength, but the cost is also increased accordingly. The specific choice of which steel can be weighed according to actual needs and budget. At the same time, the surface treatment of steel is also an important factor affecting the performance of tooling. For example, sandblasting, galvanizing and other treatments can improve the corrosion resistance and aesthetics of steel, and further extend the service life of tooling. In the embodiment, the connection method of the tooling module is also worth noting. Bolting, welding and other methods can be used. The specific choice depends on the use environment and requirements of the tooling.

[0106] See also Figure 31 and Figure 32 In some embodiments, the tooling module is connected to a vehicle body reinforcement 9 , which is used to connect to the side of the crossbeam of the test module.

[0107] In this embodiment, the reinforcement effectively enhances the structural strength and stability of the connection, preventing failure or deformation caused by stress concentration during testing, ensuring the reliability of the mechanical transmission path, and thus improving test accuracy. Furthermore, it reduces the risk of tooling damage during testing, extending its service life and reducing maintenance and replacement costs, thereby achieving the multi-dimensional goal of reducing costs and increasing efficiency for strength test tooling.

[0108] In the above embodiment, the body reinforcement 9 is welded or bolted to the tooling module. The addition of the body reinforcement 9 ensures the stability and load-bearing capacity of the entire tooling structure. This connection method not only facilitates installation and removal but also allows for quick replacement or adjustment of the reinforcement 9 when needed to accommodate different seat models or changing testing requirements. Furthermore, the welded or bolted connection offers high reliability, capable of withstanding the heavy loads during testing, effectively preventing loosening or failure of the connection, and further enhancing the safety and stability of the tooling.

[0109] See also Figure 32 In this embodiment, bolt connection holes 10 are reserved on the sliding test platform. The tooling module and the sliding test platform are fixed together by bolts at the bolt connection holes 10. This bolt connection method is easy to operate and provides a stable connection. It can ensure that the tooling module will not loosen or fall off due to excessive force during the test process, thereby ensuring the accuracy and safety of the test. At the same time, the bolt connection also facilitates the disassembly and reassembly of the tooling, allowing the tooling to flexibly adapt to different testing requirements, improving the tooling utilization rate and testing efficiency. In addition, the position and number of the reserved bolt connection holes 10 can be adjusted according to actual needs to meet the testing requirements of different vehicle seat models and their fixings, further enhancing the versatility and flexibility of the tooling.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
