Problems solved by technology

If the vehicle is not equipped with an anti-rollover device, there will be a great danger. In severe cases, the vehicle will rollover, which may easily cause casualties
[0003] At present, the trigger switch device of the existing mechanical anti-rollover device is relatively simple. Although it can effectively exert the anti-rollover effect, there may be the following problems: it may be accidentally triggered during normal driving of the vehicle (without making a sharp turn); It cannot make the driver feel the danger of vehicle rollover in advance, that is, it cannot perform rollover warning; it cannot automatically recover after triggering the vehicle anti-rollover system once; it cannot be widely applied to different models

Embodiment 1

[0037] like figure 2 A dual-factor linkage trigger switch device is shown, which has a torque loader 2-10 and a corner trigger 2-20, wherein, as shown in FIG. figure 2 As shown, the torque loader 2-10 includes an action cylinder housing 2-4 and a piston limit nut 2-3 threaded at the port of the action cylinder housing 2-4. The action cylinder housing 2-4 There is a medium cavity and a moment loading piston 2-5. The moment loading piston 2-5 includes a piston head and a piston rod, and a sealing rubber ring 2-1 is arranged on the peripheral side of the piston head. The moment loading piston 2 The piston rod of -5 passes through the piston limit nut 2-3 and is connected to the linkage switch assembly. Between the torque loading piston 2-5 and the piston limit nut 2-3, a Piston return spring 2-2, the medium cavity of the torque loader 2-10 communicates with an external pressure source, and controls the extension or retraction of the piston rod with the pressure increase or pre...

Embodiment 2

[0061] The difference from Embodiment 1 above is that in this embodiment, the two-factor linkage trigger switch device can also be applied to prevent the pitch stall of the aircraft, and the system is suitable for models with different stall speeds and stall elevation angles; At the flight speed, it has the function of preventing the pitching stall of the aircraft.

[0062] like Figure 8 As shown in the figure, the corner trigger 2-20 is connected with the aircraft steering stick, and the linkage relationship between the steering stick and the corner trigger 2-20 is: when the steering stick is pushed, the corner trigger 2-20 rotates clockwise; when the steering stick is pulled, the corner The trigger turns counterclockwise.

[0063] The nozzle of the moment loader 2-10 is connected with the aircraft pitot tube to feel the static pressure of the aircraft pitot tube.

[0064] The trigger switch 2-11 and the trigger switch 2-12 are respectively connected to the horizontal stab...

Abstract

The invention discloses a double-factor linkage type trigger switch device, which belongs to the technical field of control switches, and comprises a torque loader, a linkage switch assembly and a rotation angle trigger. The moment loads the piston, and the piston rod of the moment load piston is connected to the linkage switch assembly, the piston rod is sleeved with a piston return spring, and the medium chamber of the torque loader is connected to the external pressure source; the linkage switch assembly includes a fork arm and a toggle hinged with the fork arm The left side of the toggle lever is connected to a trigger lever extending up and down, the two trigger levers are respectively provided with trigger switches, and the left side of the toggle lever is connected with a linkage switch return spring; the corner trigger includes an oval turntable, and its Has rotating sides that can make smooth contact with pulleys. The present invention can assist and effectively play the anti-rollover function, and has the advantages of no accidental triggering, rollover warning and automatic reset, and can be widely applied to different vehicle models.

Description

technical field [0001] The invention relates to the technical field of control switches, in particular to a double-factor linkage type trigger switch device. Background technique [0002] When the vehicle is driving normally, it will maintain its balance due to its own weight. When the vehicle turns sharply (that is, the vehicle speed is fast and the steering wheel is turned at a certain angle), the inertia will generate a force perpendicular to the forward direction of the vehicle. When the moment on the wheels is insufficient to overcome the lateral centrifugal force of the car, the car rolls over. If the vehicle is not equipped with an anti-rollover device, there will be great danger. In severe cases, the vehicle will roll over, which may easily cause casualties. [0003] At present, the trigger switch device of the existing mechanical anti-rollover device is relatively simple, and although it can effectively play the role of anti-rollover, there may be the following pro...
