Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the present invention provides a fast moving driver seat 100 for a locomotive, wherein the driver seat 100 includes a seat body 1, and a movable base 2 is disposed between the seat body 1 and a floor of the locomotive; the movable base 2 comprises a bottom plate 21 fixedly arranged on a floor, the front end and the rear end of the bottom plate 21 are respectively pivoted with a front side plate 22 and a rear side plate 23 which are arranged in parallel, the upper ends of the front side plate 22 and the rear side plate 23 are respectively pivoted with a top plate 24, and the top plate 24, the bottom plate 21, the front side plate 22 and the rear side plate 23 form a parallel four-bar mechanism; the initial positions of the front side plate 22 and the rear side plate 23 are in a forward tilting state forming an included angle with the vertical plane 3; the front side plate 22 is provided with a resetting device 4 which enables the front side plate 22 to swing backwards. In the present embodiment, the included angle may be set to about 1 to 5 degrees, and the main purpose is to avoid the situation that the movable base 2 cannot move forward when the driver sits on the seat.

As described above, when the driver sits on the locomotive quick-moving driver seat 100 of the present invention, the movable base 2 is driven to swing forward by the weight of the driver, so that the driver is located at the driving position; when the driver leaves the seat, the movable base 2 is retracted to the initial position under the action of the resetting device 4, and at the moment, a large space is left in the front position of the seat 100 to facilitate the movement of the driver. Therefore, the utility model discloses a driver seat can guarantee that the driver flees fast under emergency appears.

Further, in the present embodiment, as shown in fig. 3 and 4, the reset device 4 is composed of two tension springs 41 arranged in parallel, one end of each of the tension springs 41 is connected to the rear end of the bottom plate 21 (in the present embodiment, the end is connected to a torsion spring support frame described below), and the other end is connected to the upper end of the front side plate 22; when the driver leaves the seat, the two tension springs 41 pull the front side plate 22 to swing backward to return to the original position.

In the present embodiment, as shown in fig. 3 and 4, two

torque resistance rods

51, 52 are provided on the base plate 21 so as to be staggered in the front and rear directions near the rear end position thereof, and the

torque resistance rods

51, 52 are fixed to the base plate 21 by a torsion spring support 53; a torsion spring 54 is connected between each of the

torque resistance rods

51, 52 and a torsion spring support 53. When a driver sits on the seat, the front and

rear side plates

22 and 23 of the movable base swing forwards, and at the moment, the rear side plate 23 sequentially contacts with the free ends of the

torque resistance rods

51 and 52 to play a role of buffering; to reduce friction between the rear plate 23 and the free ends of the torque resistance rods, the free ends of the

torque resistance rods

51, 52 are provided with rollers 55.

In order to increase the cushioning force when a driver sits on the seat, as shown in fig. 3 and 4, in the present embodiment, a resistor 6 is vertically arranged on the bottom plate 21 near the front end thereof, and the resistor 6 may be a hydraulic resistor or a spring resistor. The upper end of the resistance device 6 is provided with a roller 61. When the top plate 24 moves to contact with the roller 61, the resistor 6 can generate an upward counter force to the top plate 24 to slow down the downward movement of the top plate 24.

Furthermore, in the present embodiment, in order to prevent the movable base 2 from rotating backward from the initial position, a stop member 7 for limiting the front side plate 22 and the rear side plate 23 from swinging backward from the initial position is further fixed on the bottom plate 21 of the movable base; in the present embodiment, the limiting member 7 may be a limiting screw 71 disposed on the torsion spring supporting frame 53, and a stopper (not shown) is fixed on the front, rear side plate or the top plate, and in the initial position, the stopper just abuts against the limiting screw 71 to prevent the front, rear side plate or the top plate from swinging or moving backwards.

As another example of the present embodiment, the limiting member 7 may be a limiting block (not shown) disposed behind the rear side plate 23, and when the movable base is at the initial position, the rear side plate 23 just abuts against the limiting block to prevent the movable base from swinging backwards.

The working principle of the movable base of the driver seat 100 of the present invention is as follows (as shown in fig. 5):

when a driver sits at the position 1, the movable base 2 moves forwards under the action of the weight of the driver, overcomes the tension of the tension spring 41 and moves to the position 2; at this time, the rear side plate 23 sequentially contacts the torque resistance bar 51 and the torque resistance bar 52, and receives a buffering action of the torsional resistance; as the roof panel 24 hits the vertical resistor 6 and experiences more resistance as it continues to advance to position 3, the mobile base 2 moves to position 4 with increasing resistance. Through the four-stage damping (buffering) resistance function, drivers with different heights, weights and other human body sizes can sit on the driver seat 100, and the drivers can move forward to the working position (driving position) lightly and smoothly when sitting on the seat. When the driver leaves the seat 100, the movable base 2 can be quickly restored to the initial position under the action of the resetting device 4. From this, when emergency appears, the driver only need push the control panel, and this movable base 2 can drive seat body 1 translation backward, makes the driver can be convenient swift leave seat 100, guarantees that the driver can flee fast under emergency.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
