Here, the preset swing angle refers to a minimum swing angle of the vehicle body 01.
Specifically, when the swing angle detection piece detects that the current swing angle of the vehicle body 01 is greater than or equal to the preset swing angle, the swing angle detection piece sends a signal to the controller, the controller simultaneously controls the first swing stopping arm 1 and the second swing stopping arm 2 to continuously extend out of the abutting surface, the acting force applied to the abutting surface by the first swing stopping arm 1 and the second swing stopping arm 2 is increased, and therefore the swing amplitude of the vehicle body 01 is reduced; when the swing angle detection piece detects that the current swing angle of automobile body 01 is less than preset swing angle, meaning automobile body 01 does not swing almost, swing angle detection piece signals to controller, and the controller controls simultaneously that first only swing arm 1 and second only swing arm 2 shrink in order to keep away from the butt face to reduce first only swing arm 1 and second and only swing arm 2 and apply the effort to the butt face, be favorable to realizing energy-conservingly.
Further, the utility model discloses still including the first length detection piece that is used for detecting the first flexible length of only swing arm 1 and the second length detection piece that is used for detecting the second and only swing arm 2 flexible length, first length detection piece and second length detection piece all link to each other with the controller. Alternatively, the first length detecting member and the second length detecting member may each be a length detecting sensor, but are not limited thereto.
The controller is used for controlling the first end swing arm 1 or the second end swing arm 2 to stretch out and draw back until the two flexible length equals according to the signal that first length detection piece and second length detection piece sent when the flexible length of first end swing arm 1 and second end swing arm 2 is unequal correspondingly to the flexible length of automatic adjustment first end swing arm 1 and second end swing arm 2 prevents that automobile body 01 from inclining, is favorable to promoting the security.
Specifically, when the telescopic length of the first swing stopping arm 1 is not equal to the telescopic length of the second swing stopping arm 2, the first length detecting part and the second length detecting part simultaneously send signals to the controller, and the controller independently controls the first swing stopping arm 1 to realize telescopic motion or independently controls the second swing stopping arm 2 to realize telescopic motion until the telescopic length of the first swing stopping arm 1 is equal to the telescopic length of the second swing stopping arm 2; otherwise, the controller controls the first swing stopping arm 1 or the second swing stopping arm 2 not to act.
Referring to fig. 2, fig. 2 is a schematic view of a suspension type monorail train anti-sway device according to a second embodiment of the present invention.
The utility model discloses still provide the second kind of embodiment, the second kind of embodiment only changes the first setting position that ends swing arm 1 and second and end swing arm 2, and other structures and relation of connection are all the same with first kind of embodiment.
In the second embodiment, the first swing stopping arm 1 and the second swing stopping arm 2 may also be disposed in parallel at the bottom of the floor 012, the floor 012 is disposed in the vehicle body 01, and the floor 012 is used for passengers to stand. Specifically, first telescoping cylinder 12 and second telescoping cylinder 22 all are parallel with the platform floor 012, and correspondingly, the left and right sides board of automobile body 01 all is equipped with the hole of dodging that supplies first telescoping cylinder 12 and second telescoping cylinder 22 to correspond to pass, and this mounting means can hardly see first only swing arm 1 and second from the periphery and only swing arm 2, can hardly influence the aesthetic property of automobile body 01.
It should be added that the first stop swing arm 1 and the second stop swing arm 2 may also be disposed at the bottom of the platform floor 012 in an inclined manner at a predetermined angle, where the predetermined angle is specifically an included angle between the first telescopic cylinder 12 and the platform floor 012 or an included angle between the second telescopic cylinder 22 and the platform floor 012, and the predetermined angle is specifically in a range of 0-60 °.
It should be noted that the controller includes a signal receiving unit, a signal determining unit and a signal transmitting unit, the signal receiving unit is used for receiving an electrical signal transmitted by a detecting element such as a state detecting element or a swing angle detecting element, the signal determining unit is electrically connected to the receiving unit so that the signal determining unit is used for determining whether the signal received by the receiving unit is a trigger signal, and the signal transmitting unit is electrically connected to the signal determining unit so that the signal transmitting unit transmits the determination signal generated by the signal determining unit to an executing component such as the first swing arm stop 1 or the second swing arm stop 2. The specific arrangement mode of the signal receiving part, the signal judging part and the signal sending part can refer to the prior art; in the utility model, only the application scene of the three is changed, but not the substantial improvement is carried out.
Obviously, the controller with the structure is widely applied to the existing automatic control equipment, such as an MCU, a DSP or a single chip microcomputer. The utility model discloses a key point lies in, the controller combines each driving piece and each detection piece correspondence.
