Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Example one
Referring to fig. 1 to 2, a prevent emergency brake special seat for public transport, including vehicle bottom board 1 and seat 10, vehicle bottom board 1 comprises vehicle bottom board 1a and vehicle bottom board 1b two parts that are parallel to each other, and possess between vehicle bottom board 1a and the vehicle bottom board 1b and separate chamber 2, seat 10 equidistance sets up the upper surface at vehicle bottom board 1, seat 10's back department fixedly connected with connecting block 7, it is connected with the body of rod 8 to rotate through the round pin axle on the connecting block 7, and the body of rod 8 upper portion is on the upper side to be connected with connecting block 7 rotation, so set up the moment of the 8 upsides of reducible body of rod, the upper end fixedly connected with of the body of rod 8 handrail 9 with its perpendicular setting, it has the leather packing to glue on handrail 9.
The bottom of the body of rod 8 passes bottom plate 1a on the car and extends to and separate the chamber 2 in, is equipped with heavy burden cylinder 6 in separating chamber 2, the bottom of the body of rod 8 and heavy burden cylinder 6 swing joint, and fluting 14 has radially been seted up at the middle part of heavy burden cylinder 6, and axial fixedly connected with pivot 12 in the fluting 14, and spacing groove 11 has been seted up to the axial on the body of rod 8, and pivot 12 swing joint is in spacing groove 11.
In the preferred embodiment of the invention, the vehicle bottom upper plate 1a is provided with the hollow chute 3, the width of the hollow chute 3 is 1cm-5cm larger than the diameter of the rod body 8, the rod body 8 is connected in the hollow chute 3 in a sliding manner, and the arrangement of the hollow chute 3 ensures that the rod body 8 can only slide along the hollow chute 3, thereby maximally reducing the influence on the space in the vehicle.
Further, the lateral wall that cavity spout 3 is close to handrail 9 is gone up the veneer and is had cushion 4 that adopts the rubber material, and cushion 4 adopts hemispherical structure, and cushion 4's setting can play the effect of buffering, prevents that the body of rod 8 is direct and 3 inner walls direct contact of rigid cavity spout, reduces its wearing and tearing.
In the preferred embodiment of the invention, the vehicle bottom plate 1b is provided with an arc-shaped groove 13, the load roller 6 is positioned in the arc-shaped groove 13, and the arrangement of the arc-shaped groove 13 can ensure that the load roller 6 is positioned at the inner bottom side of the arc-shaped groove 13 in a normal state, thereby avoiding the random movement of the rod body 8.
When the automobile has a sudden brake, the load roller 6 of the separation cavity 2 can continue to move forwards due to the fact that the load roller has large inertia, the load roller rotates forwards along the arc surface of the arc-shaped groove 13, the moment of the bottom of the rod body 8 is larger than the top of the load roller, the rod body 8 is far away from the lever and then drives the armrest 9 to move to one side of the seat 10, and therefore the situation that a passenger breaks away from the seat 10 and the body collides with the front back of the automobile is avoided. Meanwhile, due to the arrangement of the groove 14 in the rod body 8, when the load-bearing roller 6 moves forwards, the rotating shaft 12 slides in the groove 14 due to the compensation of the length of the rod body 8, so that the distance from a force application point on the rod body 8 to a fulcrum is prolonged, the side moment is increased, passengers can be fixed on a seat more easily, a good protection function is achieved, and the occurrence of accidental collision accidents in the old, the weak, the sick, the disabled and the pregnant can be prevented.
Example two
Referring to fig. 3 to 4, the stability of the rod body 8 in a normal state is further increased by a magnetic attraction mode, and the specific structure is as follows:
the welding has dog 5 on the vehicle bottom hypoplastron 1b, fixedly connected with permanent magnet 51 on the inner wall of dog 5, one side that dog 5 is close to heavy burden cylinder 6 is the intrados, the veneer has rubber buffer 52 on the intrados, heavy burden cylinder 6 adopts ferromagnetic material, and the coating has the anti-rust paint layer on the heavy burden cylinder 6, heavy burden cylinder 6 is attracted by permanent magnet 51 magnetism under the normality, thereby prevented in the jolt of way, the random motion of the body of rod 8, cause passenger's discomfort, compare embodiment 1 simultaneously, it also can prevent the motion that heavy burden cylinder 6 appears when going up the slope downhill path.
When a driver brakes suddenly, the load-bearing roller 6 has larger inertia, and moves forwards by neglecting the magnetic attraction of the permanent magnet 51, so that the lever motion of the rod body 8 is realized, and passengers are prevented from being separated from the seat under the sudden braking.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
