Description

Technical Field

[0001] This invention relates to the field of automotive R&D technology, specifically to a multi-system joint test bench for automobiles with integrated fault injection. Background Technology

[0002] The integrated fault injection multi-system joint test bench for automobiles is a core testing equipment in the automotive R&D and component quality inspection process. It can integrate and fix key components such as engines, motors, transmissions, and ECUs, simulate the operating environment of the whole vehicle to realize the coordinated operation of multiple systems, and at the same time verify the working performance and coordination degree of each system under normal and extreme operating conditions by artificially injecting faults such as abnormal sensor signals and short circuits, thus ensuring the reliability and safety of core automotive components and systems in advance.

[0003] Existing automotive multi-system joint test benches with integrated fault injection mostly use integral welding technology for their frame structure, with only a few non-core load-bearing parts using bolt and nut splicing. This results in a severe lack of overall structural flexibility. When it is necessary to adapt to different models of engines, motors, transmissions, and other test components, or to add fault injection modules or expand test functions, it is impossible to easily adjust the installation layout of the core test area. The welded frame must be cut and re-welded, which is not only time-consuming and labor-intensive, but also disrupts the original stress balance of the frame and exacerbates the risk of structural deformation. At the same time, when local components of the frame are damaged, it is difficult to disassemble and replace them individually. The only option is to repair welding the entire frame or scrap it, which significantly increases the cost and difficulty of subsequent maintenance.

[0004] Therefore, a solution is needed. Summary of the Invention

[0034] Solution Analysis: 1. Significantly improves the flexibility and adaptability of the frame structure. By modularly splicing the frame strips 1 (with the engagement of the retaining ring 62 and the ring groove 71), adjusting the angle (with the insertion and locking of the insert plate 76 and the retaining groove 63), and connecting in opposite directions (with the rotation mechanism 4 adjusting the orientation of the frame strips), different shapes of mounting surfaces (such as the front frame and the front window frame) can be spliced ​​as needed. At the same time, different lengths of frame strips 1 can be produced during production to adapt to the installation requirements of different vehicle parts, solving the problem that the existing welded frames cannot be easily adjusted in terms of layout and have poor adaptability.

[0035] 2. Simplify the disassembly and assembly process and improve docking efficiency. The frame assembly can be completed simply by pressing the convex surface 610 to assemble the retaining ring 62 and the ring groove 71, and the spring automatically drives the retaining block 67 to lock; the angle / direction adjustment can be done simply by moving the corresponding lever, without the need for tools. Compared with the cutting and re-welding of existing welded frames, this significantly reduces the time spent on disassembly, assembly and docking.

[0036] 3. Reduce maintenance costs and difficulty The frame adopts a modular splicing structure, and when a local component is damaged, it can be disassembled and replaced individually without the need to repair welding or scrap the entire frame. This avoids the problems of structural stress damage and high costs associated with the maintenance of existing welded frames.

[0037] 4. Ensure structural stability and testing accuracy The spring-driven bolts 52 and insert plates 76 ensure a secure locking mechanism after assembly. At the same time, the modular structure avoids residual stress caused by welding, reduces the risk of structural deformation after long-term use, and can stably guarantee the installation accuracy of test bench components and the reliability of test data.

[0038] The core innovation of this solution: Modular splicing structure design: The core splicing unit is the frame strip 1. The locking ring 62 of the first angle adjustment mechanism 6 precisely engages with the annular groove 71 of the second angle adjustment mechanism 7 of another frame strip 1. Combined with the elastic locking of the locking block 67 and the telescopic groove 82, rapid splicing and disassembly between units is achieved. The splicing unit can be configured with frame strips 2 and 3 of different lengths according to testing requirements, flexibly combining them to form mounting surfaces suitable for different components such as engines, motors, and gearboxes, solving the pain points of fixed layout and poor adaptability of traditional welded frames.

[0039] Two-dimensional angle adjustment mechanism: Same-direction angle adjustment: By moving the second angle adjustment mechanism 7, the second lever 75 is moved to drive the slider 74 to compress the third spring 73, so that the insert plate 76 is disengaged from the slot 63. After rotating the frame bar 1 to the target angle, the second lever 75 is released. The insert plate 76 is reset and inserted into the corresponding slot 63 under the action of the third spring 73, so as to achieve angle positioning within the range of 0-360° and adapt to different installation tilt angle requirements.

[0040] Reverse direction adjustment: Move the lever 55 of the locking mechanism 5, which drives the plug 52 to compress the spring 53 through the connecting block 54, so that the plug 52 disengages from the bolt hole 410 of the locking plate 41. With the help of the bearing 46, bearing 47 and connecting shaft 48 of the rotating mechanism 4, rotate the frame bar 3 to the desired orientation. After releasing, the plug 52 is inserted into the corresponding bolt hole 410 and locked under the action of the spring 53, so as to realize the flexible switching of the installation direction.

[0041] Spring-driven self-locking system: All key connection parts adopt a spring-driven locking design. The spring 53 of the locking mechanism 5 drives the plug 52 to achieve self-locking of the rotation mechanism 4. The spring 66 of the first angle adjustment mechanism 6 drives the locking block 67 to achieve self-locking of the splicing unit. The spring 73 of the second angle adjustment mechanism 7 drives the insert plate 76 to achieve self-locking after angle adjustment. The spring 85 of the releasing mechanism 8 ensures that the push block 86 is reset and assists in unlocking. Locking and unlocking operations can be completed without additional tools, improving the convenience of operation while ensuring connection stability.

[0042] Integrated loosening auxiliary structure: A loosening mechanism 8 is set near the second angle adjustment mechanism 7. By pressing the convex surface 87 of the push block 86, the locking block 67 can be pushed to compress the spring 66 and disengage from the telescopic groove 82, quickly releasing the splicing lock. In conjunction with the limiting groove 83 and the limiting groove 84, the limiting plate 88 and the limiting plate 89 are guided and limited, ensuring that the loosening operation is precise and controllable, further simplifying the disassembly and assembly process and reducing the difficulty of maintenance.

[0043] Integrated molding combined with flexible adaptation: Frame strip 12 is integrally molded with locking plate 141, connecting plate 61, retaining ring 62, and partition plate 64; frame strip 23 is integrally molded with locking plate 242; connecting shaft 48 is integrally molded with fixing plate 49; bolt 52, connecting block 54, and break block 1 55 are integrally molded; slider 74, break block 2 75, and insert plate 76 are integrally molded; push block 86, convex surface 2 87, limiting plate 1 88, and limiting plate 2 89 are integrally molded, ensuring structural strength; at the same time, the elastic contact design of anti-slip pad 1 69 and anti-slip pad 2 77 improves the friction and fit of the splicing surface, avoids residual welding stress, and reduces the risk of structural deformation.

[0044] Working principle: The frame strip 1 of this solution is easy to assemble and disassemble, has high docking efficiency, adjustable docking angle, and can be rotated for opposite-direction docking. Specifically: When docking one frame strip 1 with another frame strip 1, the two protrusions 610 on the retaining ring 62 of one frame strip 1 can be pressed inward with two fingers until the protrusions 610 retract into the telescopic groove 65. Then, the retaining ring 62 is aligned with the annular groove 71 of the other frame strip 1 and inserted until the two protrusions 610, under the force of the spring 66, are pushed into the telescopic groove 82 along with the retaining block 67 through the bearing 81. At the same time, the insert plate 76 directly docks with the nearest retaining groove 63, and the docking of the two frame strips 1 is completed. If you want to adjust the angle between the two frame strips 1 so that they can be spliced ​​into different surfaces (such as the front frame and the front window frame), you can turn the lever 75 to pull out the insert plate 76 and keep it in place. Then, directly rotate the frame strip 1 that needs to be rotated so that the retaining ring 62 rotates accordingly. After the angle is adjusted, release the lever and insert the insert 76 into the retaining groove 63 under the force of the spring 73 to fix it. If different directions of installation are required, the lever 55 can be turned to pull the bolt 52 out of the bolt hole 410 and hold it in place. Then, the frame bar 3 is rotated and the locking plate 42 is rotated until the ring groove 71 is adjusted to the desired orientation. After that, the lever is released and the bolt 52 is reset to the bolt hole 410 by the spring 53 and fixed. This determines the angle of the frame bar 1 when it is installed. The angle can be adjusted by the retaining ring 62 to achieve the desired angle. In this product, the frame bar 1 of different total lengths can be set during production to meet the installation effect of different parts. That is, the lengths of frame bar 2 and frame bar 3 are increased or shortened simultaneously.

[0045] Technical effects of implementing this solution: This solution addresses the shortcomings of existing welded test bench frames, which suffer from poor flexibility, complex assembly and disassembly, and high maintenance costs. Through modular splicing, spring-driven locking, and adjustable angle / direction structural design, it improves the adaptability and ease of operation of the frame while reducing maintenance costs and ensuring structural stability. It effectively meets the requirements of automotive multi-system joint test benches that require frequent adjustments to component layout and long-term stable operation.

These components are all general standard parts or components known to those skilled in the art.

This results in poor flexibility in component adaptation and functional expansion, requiring overall modification for local maintenance, which is costly and easily damages the stability of the frame structure. This invention solves the pain points of the existing welded test bench frame by using modular splicing, spring-driven locking, and adjustable angle / direction design. It improves adaptability and ease of operation, reduces maintenance costs, ensures stability, and meets the core requirements of the test bench.
