Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a vehicle assistance apparatus, and particularly relates to an apparatus for realizing overall lifting, omnidirectional rotating and moving and obstacle crossing of a vehicle. 
       BACKGROUND 
       [0002]    With the rapid development of an economic society, the human living standard is increasingly improved, and a vehicle serving as a main transportation means for human travel is quite popular. The vehicle not only provides travel convenience for people, but also brings a driving pleasure to a driver. However, with the continuous increase of vehicles, problems of parking difficulty, running difficulty and the like appear constantly, and a lot of troubles are brought to people as follows: the vehicle cannot normally go in and out due to insufficient residual road parking length; the vehicle cannot turn around due to an extremely small site or space; the vehicle cannot make a turn due to a sharp turn; the vehicle cannot intersect or pass due to an extremely narrow rural road surface; the vehicle cannot cross part of obstacles; the vehicle cannot be transferred to a safety zone in time due to midway breakdown, and the like. Traffic accidents may be caused if some conditions are improperly handled. At present, a vehicle is generally designed as follows: four wheels are down to the ground, lengths of a wheel track and a wheel base and a height of a chassis are constant, and the vehicle only can go forward and backward and run to left front, left rear, right front and right rear, has a large turning radius and does not have functions of performing overall side movement and in-situ rotation or passing through a road surface narrower than the wheel base, a ditch wider than a wheel diameter and crossing obstacles. Therefore, a novel apparatus is urgently needed to overcome and solve the above problems. 
       SUMMARY 
       [0003]    A purpose of the present invention is to provide a multifunctional vehicle lifting, steering, moving and obstacle crossing device. The apparatus overcomes defects that a vehicle has constant wheel position and chassis height during use, only can go forward and backward and run to left front, left rear, right front and right rear and cannot realize four-wheel off-ground, overall side movement and in-situ rotation or pass through a narrow road, a wide ditch and a high and narrow obstacle, thereby effectively increasing maneuvering performance of the vehicle, particularly increasing overall lifting, omnidirectional steering, moving and obstacle-crossing capabilities of the vehicle, and effectively avoiding complicated operations brought by use of a jack and other lifting tools during tire changing. Therefore, the apparatus in the present invention is required to simultaneously have functions of lifting, rotation, running, convenient carrying, actual operation and control and the like. 
         [0004]    The present invention is realized through technical solutions as follows: the multifunctional vehicle lifting, steering, moving and obstacle crossing device includes a rotating mechanism, a lifting mechanism, a running mechanism and a control mechanism. An upper part of the rotating mechanism is mounted on a lower plane of a vehicle chassis; a lower part of the rotating mechanism is connected with an upper end of the lifting mechanism; a lower part of the lifting mechanism is connected with the running mechanism, and preferably, positions of the rotating mechanism and the lifting mechanism are changeable; a main body of the control mechanism is mounted on the rotating mechanism or the lifting mechanism or a body mountable part; the control mechanism is connected with a driving motor at each part and an external information receiving device through circuits; and the entire multifunctional vehicle lifting, steering, moving and obstacle crossing device can be controlled in a wired or wireless manner. At ordinary times, the lifting mechanism of the multifunctional vehicle lifting, steering, moving and obstacle crossing device in the present invention is folded and tightly attached to the vehicle chassis entirely in a flat form, thereby avoiding influencing normal running of the vehicle. 
         [0005]    Preferably, the driving motor is a hydraulic motor. 
         [0006]    When the vehicle needs to perform overall side movement, for the multifunctional vehicle lifting, steering, moving and obstacle crossing device in the present invention, the rotating mechanism rotates under control of the control mechanism, to drive the lifting mechanism and the running mechanism to rotate to a preset side movement direction, and the lifting mechanism is extended to support the entire vehicle body, so that the wheels leave the ground, and the running mechanism runs to an assigned direction according to a control instruction. When the vehicle needs to change a direction in a running process, change of the direction can be realized through a speed difference or reverse rotation of roller groups or transmission belt plates on left and right sides of the running mechanism under control of the control mechanism. 
         [0007]    When the vehicle needs to rotate in situ or turn around, for the multifunctional vehicle lifting, steering, moving and obstacle crossing device in the present invention, the lifting mechanism is extended to support the entire vehicle body under the control of the control mechanism, so that the wheels leave the ground, and the rotating mechanism drives the vehicle body to rotate according to a preset angle or a manual operation. 
         [0008]    When the vehicle needs to pass through a narrow road surface, for the multifunctional vehicle lifting, steering, moving and obstacle crossing device in the present invention, the lifting mechanism is extended to support the entire vehicle body under the control of the control mechanism, so that the wheels leave the ground, and the vehicle runs by virtue of the running mechanism. 
         [0009]    When the vehicle needs to cross the high and narrow obstacle having a width smaller than a transverse or longitudinal spacing between the multifunctional vehicle lifting, steering, moving and obstacle crossing device in the present invention and the wheel, for the multifunctional vehicle lifting, steering, moving and obstacle crossing device in the present invention, the lifting mechanism is extended to support the entire vehicle body under the control of the control mechanism, so that the chassis is higher than the obstacle, and the vehicle runs by virtue of the running mechanism, or the vehicle body is rotated by 90 degrees by using the rotating mechanism and then transversely runs according to needs; and therefore, the obstacle passes through a gap between the apparatus in the present invention and the wheel. 
         [0010]    When the vehicle needs to pass through a wide ditch which is not wider than a longitudinal distance between the wheel and the multifunctional vehicle lifting, steering, moving and obstacle crossing device in the present invention, for the multifunctional vehicle lifting, steering, moving and obstacle crossing device in the present invention, the lifting mechanism is extended to support the entire vehicle body under the control of the control mechanism, so that the wheels leave the ground, and the vehicle runs by virtue of the running mechanism until front wheels or rear wheels run across the ditch; then the lifting mechanism is retracted; the vehicle is laid down; the vehicle normally runs to the apparatus in the present invention and then passes through the ditch; and the above actions are repeated to enable the vehicle to be continuously driven until the rear wheels or the front wheels of the vehicle stride across the ditch. 
       BENEFICIAL EFFECTS 
       [0011]    The present invention has advantages as follows:
       1. The present invention is directly mounted below a vehicle chassis, is convenient to use and does not increase extra burden and workloads such as carrying, transporting, loading and unloading, etc.;   2.
