Large-size vehicle body automatic leveling system and method based on six-point support

Abstract

The invention belongs to the technical field that when a vehicle runs with specific actions or under specific conditions or being operated by a driver, the responsivity is adopted as the feature and discloses a large-size vehicle body automatic leveling system and method based on six-point support. The large-size vehicle body automatic leveling system comprises a controller, a double-shaft tilt angle sensor, a human-computer interface, an alarm device, six support legs, six direct current motor drivers and six Hall sensors. By means of the large-size vehicle body automatic leveling system, thehighest point in a leveling support leg is maintained to be unchanged, remaining support points move upwards synchronously to be aligned with the highest point, and when all the remaining points reach the position of the highest point, a vehicle body is in the horizontal state; at the force adjustment stage, it is guaranteed that all tyres leave the ground and do not play the support role, and the whole vehicle body is supported by the six support legs; meanwhile, fine adjustment is conducted, and it is guaranteed that the six support legs are stressed uniformly. By means of the large-size vehicle body automatic leveling system, automatic leveling of a platform can be achieved in an outdoor unstructured environment; and the system has the advantages of being high in leveling precision, speed and reliability, great in stability and the like and is particularly applicable to the electronic equipment vehicle-mounted platform or various campsite motor homes.

Description

technical field [0001] The invention belongs to the technical field characterized by their responsiveness when the vehicle is running under special actions, special conditions, or the driver's operation, and in particular relates to an automatic leveling system and method for a large vehicle body based on six-point supports . Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: with the development of automation technology, automatic leveling technology is more and more widely used in people's production and living fields, such as electronic equipment vehicle-mounted platforms, camping cars, etc. This type of car body has many carrying facilities and needs enough space for activities. Therefore, during use, due to the user's activities and the placement of various facilities, the center of gravity of the car body will shift, and it only depends on the tires. The support can neither guarantee the level of the car b...

Problems solved by technology

[0004] (1) At present, the hydraulic leveling system commonly used in China cannot meet the working requirements of an unstructured environment, and it is difficult to maintain a balanced state after leveling for a long time. In addition, it has disadvantages such as inconvenient use and difficult maintenance.

[0005] (2) With the increase of demand, the span and load of large car bodies are gradually increasing, and the requirements for indicators such as leveling time and balance are also getting higher and higher. However, due to the number of supporting legs The rigidity of the long-span and heavy-duty car body cannot be satisfied, and the hydraulic leveling system cannot meet high leveling accuracy and achieve rapid leveling

[0007] The difficulty in solving the above technical problems lies in: in order to meet the rigidity of the long-span heavy-duty vehicle body, a six-point support leveling system is required. The six-point support is a cubic static indeterminate problem. The control strategy design and stability control of the system The difficulty is high; in order to meet the high leveling accuracy and achieve fast leveling, the servo system of each outrigger needs to have fine control and a feedback control system with complex functions, so the structure of the six-point leveling system is complex and the cost is high
