Technical Field
[0001] This utility model relates to the field of small vehicle technology, and more specifically to a vehicle frame for a drive-by-wire chassis of an intelligent small car. Background Technology
[0002] A smart car is a device that can be programmed to complete a predetermined goal by giving it specific instructions in advance. Smart cars can greatly reduce the workload of human workers, and because of their excellent tracking and obstacle avoidance functions, they are widely used in military, medical, logistics, and home applications.
[0003] The most common use cases for intelligent vehicles are currently in schools or enterprises for learning, development, and testing. Therefore, the requirements for the chassis structure of these vehicles are low cost, easy assembly and disassembly, high versatility, and easy manufacturing. As intelligent vehicles are increasingly used for algorithm verification and development testing of autonomous driving, they need to install more sensor hardware devices, such as LiDAR and millimeter-wave radar. This places higher demands on the chassis installation space, leading to increased industry demand for drive-by-wire chassis frames for functions such as algorithm calibration of various sensors and real-scene mapping. However, traditional drive-by-wire chassis for intelligent vehicles have relatively fixed mounting holes, resulting in poor flexibility and limited expandability. Therefore, there is an urgent need to develop an intelligent vehicle chassis frame that can be adjusted and installed with various devices to suit specific needs, and also possesses flexibility and expandability.

[0004] Purpose of the utility model: The purpose of this utility model is to address the shortcomings of the existing technology by providing a vehicle frame for a drive-by-wire chassis of an intelligent vehicle, so that the mounting hole positions can be adjusted and flexibly expanded as needed.
[0005] To solve the above-mentioned technical problems, this utility model discloses a vehicle frame for a drive-by-wire chassis of an intelligent car, including four columns, several crossbeams, several side beams, and a shelf fixed on the crossbeams and side beams. The vehicle frame is divided into multiple layers by the shelf, and each layer consists of two crossbeams, two side beams, and a shelf forming a rectangular placement space. The two ends of the crossbeams and side beams can be detachably connected to the opposite side of the two columns. The shelf is provided with various mounting holes and slots.
[0006] Furthermore, multiple limiting grooves for fixing the shelves are provided on the crossbeams and side beams.
[0007] Furthermore, the limiting groove includes a horizontal slot and a vertical slot. The limiting groove is an angular structure with adjustable stops.

[0009] Furthermore, the columns, beams, and side beams are all wrapped with carbon fiber film to enhance the load-bearing capacity of the beams.
[0010] Furthermore, a supporting frame is welded between the crossbeam and the side beam.
[0011] Furthermore, shock-absorbing pads are provided between the crossbeams, side beams and the shelf, enabling the shelf to achieve zoned shock and vibration prevention, protecting the stability of the equipment and sensors on it, and providing strong anti-interference capabilities.
[0012] Furthermore, the spacing and length of the mounting hole stop grooves are configured accordingly based on different models of hardware devices.
[0013] Beneficial effects: Compared with the prior art, this utility model has the following advantages: It adopts a layered structure with multiple mounting holes on the shelf, which can flexibly expand accessories and facilitate modular replacement. The crossbeams, side beams and shelf are provided with shock-absorbing pads, which enable the shelf to achieve zoned anti-vibration and anti-shaking, protect the stability of the equipment and sensors on it and have strong anti-interference ability.
