Description

Technical Field

[0001] This utility model relates to the field of chassis testing technology, and in particular to a new energy sightseeing vehicle chassis simulation driving platform. Background Technology

[0002] New energy sightseeing vehicles are regional transportation vehicles powered by electricity or other clean energy sources. They are mainly used in scenic spots, parks and other specific locations to receive tourists. They are characterized by low operating costs, low noise during operation, and no exhaust emissions during use. The performance and safety of the vehicle largely depend on its chassis structure. The chassis of new energy sightseeing vehicles is usually made of steel or aluminum alloy. The design of the chassis is directly related to the vehicle's load-bearing capacity, driving stability and passability, and it is the basic platform of the whole vehicle.

[0003] Currently, to better suit scenic areas and enhance the visitor experience, the exterior designs of new energy sightseeing vehicles are becoming increasingly diverse. For example, one type of electric sightseeing vehicle, with announcement number CN221819864U, uses a rear-mounted driver's seat to simulate a locomotive for pulling the carriages. This diversity means that the new energy sightseeing vehicle chassis, as a basic universal platform, needs to be adapted to various vehicle bodies and driving layouts after leaving the factory. Against this backdrop, traditional chassis testing methods face significant challenges. If driving tests are conducted only after the chassis has been matched with a specific body to form a complete vehicle, any problems discovered require the chassis to be disassembled and returned to the factory for repair—a cumbersome and time-consuming process. Another approach to identify problems before leaving the factory is to manufacture a dedicated complete prototype for each chassis adapted to different body bodies. However, while this method allows for early detection, it requires substantial manufacturing costs, and the installation and disassembly of the prototype are equally difficult and inefficient, resulting in a still lengthy testing cycle that cannot meet the demands of efficient production. Utility Model Content

It consists of a frame, fixing components, operating components, and control connection components. Two docking points are installed on the frame, which can be mounted at any position on the chassis longitudinal beams. Multiple fixing components enable a quick, universal, and robust connection between the frame and the chassis longitudinal beams. Furthermore, the steering mechanism integrated on the frame is directly connected to the chassis steering structure. The control connection components located on the outside of the frame connect to the chassis's electrical and hydraulic control components, thus forming an independent and complete testing unit. This allows for comprehensive driving simulation and functional testing of the new energy sightseeing vehicle chassis without the need for a complete vehicle body, greatly improving the efficiency and safety of chassis factory testing and significantly reducing the costs associated with manufacturing various test prototypes.
