Problems solved by technology

[0007] 1. The concept of dividing the front and rear of the existing frame structure is used to manufacture each part in sections, so that each part is a part of the frame, thereby reducing the size of the manufacturing process, and each part needs to be additionally locked. Points for assembly and combination. However, tolerance problems will occur in the production of each component. Too many locking points will reduce the accuracy of the overall frame and seriously affect the quality of the finished frame structure.
[0008] 2. The division principle of the existing frame structure (assembly points) does not consider the strength relationship of the overall frame, resulting in the need to increase the strength of the locking points of each component, thereby increasing the steel structure and flesh thickness, resulting in vehicle weight increase, which increases the overall cost of the frame structure
[0009] 3. The principle of division of the existing frame structure cannot effectively achieve modular assembly
That is, when the power control bearing device of the vehicle and the vehicle body device for the vehicle are first assembled with the parts of the frame structure, since the power control load device and the car body device are all dispersed on the parts of the frame structure, the Before the components of the structure are combined, the power control load-carrying device cannot independently perform quality control tests on driving dynamics and safety, and the car body device cannot independently perform quality control tests such as light signal functions and shell tolerance
The above test can only be carried out after the frame structure has been assembled, and the power control bearing device and the car body device are also completely assembled on the frame structure to form a complete vehicle. Therefore, if the test fails, it must be completely assembled. The disassembly of the vehicle is not only labor-intensive, but also a waste of time and cost for maintenance and testing
[0010] 4. Due to the cost considerations of welding equipment, the existing vehicle frame structure is concentrated in an integrated manner. Because the strength and precision required for each component of the vehicle frame structure depends on the load on it as the power control bearing device or vehicle body device, there are different, but because there is no systematic division of the load for each component, the overall machining accuracy must be matched with components with high precision and strength requirements, resulting in waste of processing for components with low precision requirements
[0011] Another example is TW New Patent Announcement No. 396122 "Scooter type locomotive", although its frame structure is only divided into two parts, its power control bearing device and car body device are still mixedly assembled on each part. address the above deficiencies

Embodiment Construction

[0053] First of all, although it is shown that the frame structure of the present invention is applied to an automatic two-wheeled vehicle, the present invention is not limited to be applied to an automatic two-wheeled vehicle, and may also be applied to other types of scooter-type locomotives and shifting-type locomotives. , and powered vehicles. Power vehicles such as ATV (All-terrain vehicles, all-around off-road vehicles) and snow mobile vehicles.

[0054] Please refer to Fig. 1, Fig. 2 and Fig. 3, the present invention is used to assemble the power control carrying device 1 and the vehicle body device 2 of the vehicle; the power control carrying device 1 has at least a power device 11, a carrying device 12, A driving control device 13 .

[0055] The power device 11 includes: an engine 111 , a fuel tank 112 , a transmission mechanism 113 attached to the engine 111 , and a rear wheel 114 pivotally connected to the transmission mechanism 113 .

Abstract

The invention relates to a frame structure for an automatic tumbrel comprising a power control bearing frame body and a supporting frame body for vehicle body; wherein, the power control bearing frame body is used for assembling a power control bearing device of a vehicle; the supporting frame body for the vehicle body surrounds the power control bearing frame body from two sides and is provided with more than two joint parts combined on the power control bearing frame body, and the supporting frame body for the vehicle body is used for assembling a vehicle body device of the vehicle. As the structure, the power control bearing device is assembled through the power provided by the power control bearing frame body so as to carry through the QA detections on vehicle launching, running power and security first and then carry through the QA detections on the cresset function and shell tolerance, etc., through the assembly on the vehicle body device for the vehicle by the supporting frame body of the vehicle body and then carry through the integrated combination of the whole vehicle.

Description

technical field [0001] The invention relates to a frame structure for an automatic two-wheeled vehicle. A power control load-bearing frame and a vehicle body support frame are combined to provide a power control load-bearing device and a vehicle body device for the vehicle, so that the assembly The installed power control bearing frame and the vehicle body support frame can be independently tested for quality control, and after the test is passed, the power control load frame and the vehicle body support frame are assembled to form a complete vehicle body. Background technique [0002] The frame structure is the backbone of the vehicle. Whether it is the vehicle's power, control, bearing, casing, lighting and other structures, all rely on the assembly on the frame. Only through the stable support of the frame can it play its role on the vehicle. There are functions. [0003] The main component material of the frame structure is rigid steel, but because the frame structure p...
