Description

Technical Field

[0001] The utility model relates to the technical field of flight equipment, in particular to a damping device for preventing a pilot's seat from suddenly moving backwards. Background Art

[0002] The general aircraft seat adjustment method is manual adjustment. The front and rear adjustment is done by lifting the adjustment handle to disengage the seat teeth from the slide rail slots, allowing the seat to move forward and backward along the slide rails. Release the adjustment handle to engage the teeth with the slots to secure the seat.

[0003] Due to the small cockpit space of general aircraft, pilots have to adjust their seats every time they get on and off the plane, which makes the frequency of seat adjustment high and the teeth and slots are seriously worn. For training aircraft, there are still cases where the teeth and slots are not fully engaged due to improper operation by flight trainees. The pilot's rudder pedals put a lot of backward pressure on the seat, and the pressure is even greater when the aircraft accelerates rapidly or pitches up. These factors make the probability of the aircraft seat sliding backward accidentally high. Once the pilot's seat slides, due to the fast speed and strong force, it is difficult for the teeth and slots to bite again, and the seat usually slides directly to the last limit position. If the pilot's seat slides backward accidentally, the pilot's feet will leave the rudder pedals, and suddenly pull the stick to reduce the throttle, causing the aircraft to lose directional control and quickly lift up and slow down. If it occurs in the critical stage of flight, these operations will cause the aircraft to lose control and lead to serious consequences. During flight training, flight instructors will repeatedly emphasize and remind flight trainees to check their seats to prevent accidental backward sliding, but this situation still occurs from time to time. In order to ensure flight safety, we propose a damping device to prevent the pilot's seat from suddenly moving backward, which fundamentally prevents the pilot's seat from sliding accidentally.

The liquid flow rate is large and the resistance is small, which is convenient for the seat to be quickly adjusted into place; when the pilot seat body is adjusted backward, the pilot seat body drives the cylindrical cylinder body to move backward. The one-way valve is closed at this time, and the liquid can only flow through the small hole on the piston. The liquid flow rate is small and the resistance is large, which limits the moving speed of the pilot seat body. When the seat accidentally slides backward due to the failure of the locking rod and the locking groove to engage well, the sliding speed is limited, and the seat will only move backward a small amount at a relatively small speed, which will not have a major impact on the pilot's control of the aircraft. At the same time, it is convenient for the locking rod and the locking groove to engage again, thereby avoiding the risk of aircraft loss of control and ensuring flight safety.

[0022] In the utility model, a breathable pad is provided to ventilate and dissipate heat to the driver's lower body, thereby preventing the buttocks from sweating due to long-term sitting and affecting the comfort level. A cooling fan is provided to allow external air to enter the interior of the installation box, and then the air flow is blown out through the through hole to take away the heat from the driver's lower body, thereby improving the heat dissipation effect.

[0023] In the utility model, a buffer pad is provided to comfortably wrap the driver's back, thereby preventing the driver from hitting the pilot seat body and causing damage to the driver, thereby improving the comfort level. A heating wire is provided to generate heat by energizing the heating wire, and then the heat is transferred to the buffer pad through the heat conduction plate. In an environment with a relatively low temperature, the driver can feel the temperature, thereby further improving the comfort level. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A base 1, with two slide rails 2 fixedly mounted on the top of the base 1;

[0036] A pilot seat body 4, two slide posts 3 are fixedly installed at the bottom of the pilot seat body 4, convex grooves are provided at the bottoms of the two slide posts 3, two slide rails 2 are slidably installed in the two convex grooves respectively, a connection block 28 is fixedly installed on the bottom surface of the pilot seat body 4, and a first mounting block 5 and a second mounting block 8 are fixedly installed on the top of the base 1;

[0037] The damping assembly is installed on the sides of the second mounting block 8 and the first mounting block 5 that are close to each other, and is used to buffer the backward movement impact of the pilot seat body 4.

[0038] Preferably, the damping assembly comprises:

[0039] A connecting rod 6, both ends of which are fixedly mounted on the sides of the second mounting block 8 and the first mounting block 5 close to each other;

[0040] The cylindrical cylinder body 9 is fixedly mounted on the bottom of the connecting block 28. One end of the connecting rod 6 extends into the cylindrical cylinder body 9 and is fixedly sleeved with the piston 7. A small hole 23 is opened on the side of the piston 7. A connecting hole is opened on the side of the piston 7. A one-way valve 24 is installed in the connecting hole.

Liquid is arranged in the cylindrical cylinder body 9. The diameter of the one-way valve 24 is larger than the diameter of the small hole 23.

[0041] By means of the above structure: when the pilot seat body 4 is adjusted forward, the pilot seat body 4 drives the cylindrical cylinder body 9 to move forward, so that the liquid at the rear of the piston 7 flows to the front of the piston 7. At this time, the liquid can flow through the small hole 23 and the one-way valve 24 on the piston 7. The liquid flow rate is large and the resistance is small, which is convenient for the seat to be quickly adjusted into place; when the pilot seat body 4 is adjusted backward, the pilot seat body 4 drives the cylindrical cylinder body 9 to move backward, and the one-way valve 24 is closed at this time. The liquid can only flow through the small hole 23 on the piston 7. The liquid flow rate is small and the resistance is large, which limits the moving speed of the pilot seat body 4. When the seat accidentally slides backward due to the failure of the locking rod and the locking groove to engage well, the sliding speed is limited, and the seat will only move backward a small amount at a relatively small speed, which will not have a major impact on the pilot's control of the aircraft. At the same time, it is convenient for the locking rod and the locking groove to engage again, thereby avoiding the risk of aircraft loss of control and ensuring flight safety.
