Technical Field

[0001] The invention relates to the technical field of safety seats, in particular to a railway driver's safety seat with an integrated safety airbag. Background Art

[0002] High-speed railway drivers are in a risky job, and EMU drivers do not have seat belts, airbags, anti-collision devices, or anti-crushing devices. Once an accident occurs, it is difficult for drivers to avoid casualties. However, since there is an operating console in front of the EMU cab, which has many electrical components, it is difficult to arrange an airbag detonation device. Therefore, the airbags used in vehicles such as cars in the prior art are not suitable for EMU cabs.

[0012] Furthermore, as a preference, side airbags are provided on both sides in front of the seat.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, when the deceleration applied to the slider causes it to overcome the elastic force of the spring and pull the rotating block away from the guide shaft, the restricting force between the counterweight and the guide shaft is lost, so that the counterweight can fall. This enables the counterweight to fall even if the collision sensor fails when the deceleration in the train is greater than a certain threshold.

[0015] In the present invention, when the counterweight falls, the side pull rope and the main pull rope are pulled to close the two rotating arms to the front of the seat, so that the front airbag can support the front of the driver on the seat. At the same time, the main pull rope pulls the lower pull rope to rotate the lower rod to the position where the knee airbag is lifted to the driver's knees, so as to protect the driver's knees.

DETAILED DESCRIPTION

[0021] See also Figure 1 In an embodiment of the present invention, a railway driver safety seat with integrated airbag includes a base plate 1, a seat 2 is fixed on the base plate 1, a cabinet 3 is fixed to the rear of the seat 2, a bracket 4 is fixed in the cabinet 3, and a rotating arm 5 is rotatably provided on both sides of the bracket 4. The rotating arm 5 can penetrate the cabinet 3 and extend from both sides of the seat 2 to the front of the seat 2. A baffle 6 is fixed in the rotating arm 5, and a front airbag 7 is provided on the side of the baffle 6 facing the seat 2.

[0022] See also Figure 2 In this embodiment, a main pulley 43 is rotatably provided at the center above the bracket 4, and side pulleys 51 are rotatably provided on both sides above the bracket 4. A rotating arm connecting block 52 is fixed to one side of the middle of each rotating arm 5 close to the seat 2, and a side pull rope 45 is connected to the rotating arm connecting block 52. The other ends of the two side pull ropes 45 pass around the corresponding side pulleys 51 on the same side and are connected to the main pull rope 44 together.

[0023] In this embodiment, two vertical guide shafts 41 are fixed in the cabinet 3, a counterweight 42 is slidably provided in the guide shaft 41, and the main pull rope 44 is connected to the counterweight 42 by passing through the main pulley 43. When the counterweight 42 is located above the guide shaft 41, the two rotating arms 5 are opened at the back of the seat 2, and the side pull rope 45 and the main pull rope 44 are tensioned, that is, when the counterweight 42 falls, pulling the side pull rope 45 and the main pull rope 44 can make the two rotating arms 5 close to the front of the seat 2, so that the front airbag 7 can support the front of the driver on the seat 2.

[0024] See also Figure 3In this embodiment, two symmetrical rotating blocks 421 are rotatably provided in the counterweight block 42 at positions corresponding to the two guide shafts 41. A notch is provided on the upper part of the guide shaft 41. The rotating blocks 421 can be rotated to fit into the notch of the guide shaft 41 so as to fix the counterweight block 42 and the guide shaft 41. An electromagnet 422 is fixed in the middle of the two rotating blocks 421. The electromagnet 422 can be powered on by the collision sensor. When the electromagnet 422 is powered on, it can absorb the rotating blocks 421 to keep them away from the guide shaft 41, so that the limiting force between the counterweight block 42 and the guide shaft 41 is lost, so that the counterweight block 42 can fall.

[0025] In this embodiment, the counterweight 42 is provided with a slide groove 423 at the center of the two guide shafts 41, and a slider 424 is fixed in the slide groove 423. The slider 424 is located on the side close to the seat 2. The sliders 424 are hinged to the rotating block 421 through a connecting rod 425, and a spring 426 is provided between the slider 424 and the counterweight 42. The spring 426 provides an elastic force for the slider 424 to push the rotating block 421 to fit the guide shaft 41. When the deceleration of the slider 424 causes it to overcome the elastic force of the spring 426 and pull the rotating block 421 away from the guide shaft 41, the limiting force between the counterweight 42 and the guide shaft 41 is lost, so that the counterweight 42 can fall. That is to say, when the deceleration in the train is greater than a certain threshold, the counterweight 42 can fall even if the collision sensor fails, so that the front airbag 7 rotates to the front of the driver.

[0026] See also Figure 4 In this embodiment, the seat 2 is fixed to the base plate 1 through a seat frame 21, a lower rod 8 is hinged in front of the seat frame 21, a knee airbag 9 is fixed at one end of the lower rod 8, and the knee airbag 9 can be embedded in the base plate 1 in front of the seat 2.

[0027] In this embodiment, a lower rod connection block 81 is fixed to the middle of the front of the lower rod 8, and the lower rod connection block 81 is connected to a lower pull rope 46, and the lower pull rope 46 is wound from the top of the lower rod 8 to the first seat pulley 22, and from the bottom to the second seat pulley 23, and then connected to the main pull rope 44. That is, when the counterweight 42 falls, the main pull rope 44 pulls the lower pull rope 46 to rotate the lower rod 8 to the position where the knee airbag 9 is lifted to the driver's knee, so as to protect the driver's knee.

[0028] In this embodiment, the front backrest of the seat 2 is integrated with an anti-fall airbag belt, which determines the driver's posture through wearable sensors and inflates to protect the driver when the driver tilts. The wearable sensors include but are not limited to gyroscopes, accelerometers, 3D sensors, pressure gauges, and inclination sensors. Side airbags are arranged on both sides of the front of the seat 2, which pop out under the control of the collision sensor to protect the head and ribs.

[0029] In specific implementation, when a train collision occurs, the collision sensor is triggered to energize the electromagnet 422 or the train deceleration is greater than a certain threshold, so that the slider 424 overcomes the elastic force of the spring 426 and pulls the rotating block 421 away from the guide shaft 41, the counterweight 42 and the guide shaft 41 lose the restraining force and fall down, and pulling the side pull rope 45 and the main pull rope 44 can make the two rotating arms 5 close to the front of the seat 2, so that the front airbag 7 can support the front of the driver on the seat 2. At the same time, the main pull rope 44 pulls the lower pull rope 46 to rotate the lower rod 8 to the position where the knee airbag 9 is lifted to the driver's knees to protect the driver's knees.

[0030] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
