A rapid prototyping multipurpose vehicle frame

Abstract

The invention relates to the technical field of automobile parts, in particular to a rapid prototyping multi-purpose vehicle frame, including a front frame, a first steel plate, a central frame, a third connecting structure and a rear frame, wherein the front frame comprises a lower chassis and an upper support frame, the lower chassis is arranged below the upper support frame, the lower chassis comprises a front cross beam, a rear cross beam and the first longitudinal beams, two first longitudinal beams are welded between parallel front and rear cross beams, and the upper support frame includes a first bending beam, an upper cross beam and a connecting inclined beam. The vehicle frame is convenient to assemble, and the rapid prototyping is adopted to greatly reduce the production cost andthe research and development cost of the vehicle frame. Square steel standard parts are adopted to process the front frame, the middle frame and the rear frame, thereby modularizing the production ofthe vehicle frame and further reducing the processing cost and the cost of the later maintenance of the vehicle frame.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a rapid prototyping multipurpose vehicle frame. Background technique [0002] With the sequential development of the automobile industry, the use of automobiles is becoming more and more extensive. The manufacturing method of the frame is also showing a trend of diversification. The application number is: CN02805898.4, and the title of the invention is: Motor Vehicle Mixed Bearing Frame Disclosure No. 1. The vehicle frame is processed by hydroforming. The vehicle frame is a whole. Some parts are hydroformed and then welded. There are many processing steps and complicated testing procedures, which make the production cost and research and development cost of the car high. The application number is: CN200820049194.4, and the patent titled "Off-Road Vehicle Frame" discloses an off-road vehicle frame. The frame is designed separately for off-road vehicles, and the scope of use i...

The application number is: CN02805898.4, and the title of the invention is: Motor Vehicle Mixed Bearing Frame Disclosure No. 1. The vehicle frame is processed by hydroforming. The vehicle frame is a whole. Some parts are hydroformed and then welded. There are many processing steps and complicated testing procedures, which make the production cost and R&D cost of the car high.

The application number is: CN200820049194.4, and the patent titled "Off-Road Vehicle Frame" discloses an off-road vehicle frame. The frame is designed separately for off-road vehicles, and the scope of use is limited.

Currently commonly used frames with similar usage scenarios are all independently designed and developed. Stamping or hydraulic technology is used to process the parts of the frame. There are many processing steps, complicated testing procedures, complex assembly, and long production cycles. The production cost and R&D cost are high, and the scope of application of the frame produced in this way is narrow
