[0002] During vehicle testing, signal receiving and transmission devices, positioning receiving devices, and main unit boxes need to be set up in the test site. The signal receiving and transmission devices include signal amplifiers (preferably Ruixin bridges, which are easy to set up and have low space occupation) and signal amplifier brackets. The positioning receiving devices include GPS positioning modules and GPS brackets. The main unit box serves as the data relay station for the entire test system and needs to be connected to the above two sets of equipment to realize signal aggregation and transmission.

This not only leads to a cluttered bracket layout and excessive space occupation in the site, but also makes the multi-bracket installation process cumbersome, increasing the workload of setup before vehicle testing. At the same time, the independently installed equipment lacks a linkage and fixing structure, which can easily cause problems such as GPS positioning module displacement, affecting the stability of the test signal and positioning accuracy, and thus affecting the accuracy of vehicle test data.

[0029] Solution Analysis: 1. Spatial integration and scene optimization This solution is based on the modification of the existing AP (signal amplifier) ​​bracket, integrating the main unit mounting mechanism 3 and the GPS positioning module mounting mechanism 4 with the original signal amplifier bracket 1. This solves the problem of cluttered space caused by the traditional independent arrangement of multiple brackets and significantly reduces the space occupancy rate.

[0030] Especially in scenarios like vehicle testing where a compact site layout is required, it significantly improves site utilization.

[0031] 2. Improved installation efficiency This design adopts a modular opening and closing sleeve structure (sleeve 1 32, sleeve 2 33, sleeve 3 42 and sleeve 4 43), and with the operation of the support plate and pull plate, the wrapping, alignment and fixation of each mechanism and the signal amplifier bracket 1 can be completed quickly.

[0032] This simplifies the cumbersome process of installing multiple devices independently, significantly shortens the setup time before vehicle testing, and reduces labor costs.

[0033] 3. Equipment stability and data accuracy assurance The main unit mounting mechanism 3, through the adjustable design of the expansion plate 312 and the elastic locking structure of the plug 317, can adapt to different specifications of main unit chassis and achieve stable clamping to prevent the main unit chassis from shifting.

[0034] The GPS positioning module is magnetically attached to the iron plate 49 and fixed in conjunction with the integrated bracket, which effectively avoids the GPS module displacement problem that is prone to occur when installing independently in the traditional way, ensuring positioning accuracy and signal stability, and thus improving the accuracy of vehicle test data.

[0035] 4. Improved compatibility and flexibility The expansion plate 312 features a left-right sliding adjustment design, allowing the main unit mounting mechanism 3 to be adapted to main unit chassis of different sizes, thus enhancing the compatibility of the equipment.

[0036] Meanwhile, the magnetic fixing method of the GPS module also supports quick disassembly and fine-tuning of its position, improving the flexibility of the entire system in testing scenarios.

[0037] 5. Cost control and resource reuse This solution is based on the modification of the existing AP bracket, without the need for additional independent brackets, which reduces the procurement and manufacturing costs of brackets, realizes the efficient reuse of existing resources, and has high economic efficiency.

[0038] Working principle: During installation, first hold the first support plate 38 with your left hand and pull the first pull plate 35 with your right hand to move the second sleeve 33 forward. Wrap the first sleeve 32 and the second sleeve 33 around the signal amplifier bracket 1, aligning the first bolt hole 34 with the corresponding bolt hole on the signal amplifier bracket 1. Then, push the second sleeve 33 in to clamp the signal amplifier bracket 1 and install the bolt and nut at the first bolt hole 34. Afterward, you can adjust the capacity by pulling the bolt head 320 and moving the expansion plate 312 left and right to accommodate different sizes of main unit boxes. After determining the position, release the support plate and insert the bolt 317 into the corresponding socket 310 for fixation. Hold the second support plate 48 with your right hand and pull the second pull plate 45 with your left hand. Wrap the signal amplifier bracket 1 around the top of the mounting box 31 and push the second pull plate 45 in. Then, install the bolt and nut. Attach a magnet to the bottom of the GPS positioning module using common methods and place it on top of the mounting box 41. The module will be fixed by magnetic attraction to the iron plate 49.

[0039] Technical effects of implementing this solution: This solution achieves multiple optimizations through integrated design, including space integration, improved installation efficiency, stability assurance, compatibility and adaptation, and cost control. It not only solves the pain points of traditional multi-bracket layouts but also improves equipment stability and test data accuracy through detailed design, providing an efficient and reliable equipment installation solution for vehicle testing scenarios.
