Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile research and development, especially to an experimental demonstration platform for automobile chassis research and development. BACKGROUND

[0002] As the core tool of modern transportation, a car is generally composed of four basic parts: engine, chassis, body and electrical equipment. Among them, the automobile chassis, as an important part of the automobile, bears the key role of supporting, installing the engine and its parts and assemblies, forming the overall shape of the automobile, and receiving the power of the engine to make the automobile move and ensure normal driving. In the research and development process of the automobile chassis, comprehensive and detailed inspection and research are necessary links to ensure the performance and quality of the chassis, and this process highly depends on professional experimental demonstration platforms. However, the existing experimental demonstration platforms for automobile chassis research and development can basically meet the daily use requirements, but still need to be improved in some aspects.

[0003] The experimental demonstration platform for automobile chassis research and development widely used in the current market usually adopts the lifting method of the automobile chassis lifting frame to lift the automobile chassis to a certain height difference with the ground, so that it can more intuitively inspect and research the bottom of the chassis. However, in the actual research and development experiment scene, after the experimental vehicle completes the experimental driving, due to the diversity and complexity of the experimental road, the vehicle chassis is easy to adhere to various stains from the experimental road during driving, such as dust, sand, oil stains and other impurities. When the chassis is lifted to a certain height for observation by the experimental demonstration platform, these stains attached to the surface of the chassis will seriously block the key parts and structural details of the chassis, greatly interfering with the accurate judgment of the chassis condition by the research and development personnel, and thus adversely affecting the progress of the research and development work.

[0004] To solve this problem, the traditional method is to rely on manual operation to wash the automobile chassis. However, this method has many drawbacks. On the one hand, manual washing requires a lot of manpower and labor cost, and the research and development personnel need to spend a lot of time and effort to hold the washing equipment and clean each part of the chassis one by one, which is labor-intensive and inefficient. On the other hand, manual washing cannot guarantee the comprehensiveness and thoroughness of washing, and some hidden parts of the chassis may not be effectively cleaned, resulting in residual stains and still not meeting the needs of subsequent accurate inspection and research. Therefore, we propose an experimental demonstration platform for automobile chassis research and development to solve the above problems. UTILITY MODEL CONTENTS

[0027] Figures 1 to 5 As shown, the present embodiment provides an experimental demonstration platform for automobile chassis research and development, which comprises a demonstration lifting platform 1 and a bracket 2 installed on the demonstration lifting platform 1. A base 3 is installed in the middle of the demonstration lifting platform 1. A first servo motor 4 is installed at the front end of the base 3. A lead screw 5 is rotatably connected inside the base 3. The lead screw 5 is connected to the output end of the first servo motor 4 at the front end. A threaded sleeve 7 is threadedly connected to the lead screw 5. A moving platform 6 is installed at the top end of the threaded sleeve 7. Guide grooves 8 are formed on both sides of the base 3. Guide sliding blocks 9 are installed on both sides of the moving platform 6. Two groups of guide sliding blocks 9 are located inside two groups of guide grooves 8.
