The telescopic sliding rail 1-2 comprises a rail sleeve 1-2-1 and a telescopic rail 1-2-2 arranged in the rail sleeve; the end part of the telescopic rail the bottom of the outer side of the pedal is fixedly connected.
The guy cable mechanism comprises an opening a guy cable 3-1 and a return guy cable 3-2; and the steel wire ropes of the opening inhaul cable and the return inhaul cable are respectively sleeved with an inhaul cable sleeve 3-3. One end of the opening inhaul cable 3-1 is connected to the inner side of the pedal, the other end of the opening inhaul cable is connected to the rear part of the lower edge of the side sliding door of the automobile, and the pedal is pulled to extend along with the opening of the automobile door; one end of the return cable is connected to the outer side of the pedal, the other end of the return cable is connected to the front part of the lower edge of the side sliding door 6, and the pedal is pulled to retract along with the closing of the vehicle door.
The invention also comprises an auxiliary bracket 4 fixedly arranged below the track sleeve 1-2-1, and two ends of the auxiliary bracket 4 are bent upwards to extend to the upper part of the pedal and then are connected. The main bracket 1-1 is fixedly connected with the vehicle body/frame through a connecting bracket 7.
The auxiliary support 4 is positioned on a beam below the pedal, and a fixed front support 3-4 for opening the cable sleeve and a fixed front support 3-5 for returning the cable sleeve are respectively arranged on the beam. A sliding groove 3-6 is formed in the middle of the cross beam above the pedal in the length direction of the auxiliary bracket, and a fixed rear bracket 3-7 is arranged on the sliding groove; the fixed rear bracket 3-7 comprises a bolt 3-7-1 and a locking nut 3-7-2 which are arranged in the chute; a guy cable sleeve fixing block 3-7-3 is movably arranged above the bolt, and the fixing block can freely rotate around the bolt; the opening inhaul cable and the return inhaul cable are connected with the vehicle door respectively through inhaul cable sleeves connected to the fixed blocks.
The invention also comprises a limiting device 5 arranged on the sliding sleeve, wherein the limiting device 5 comprises a fixed mounting slot 5-1 arranged at the front end of the sliding sleeve, a limiting spring 5-2 arranged in the fixed mounting slot and clamping grooves 5-3 and 5-4 arranged at the front end and the rear end of the telescopic sliding rail, and a limiting steel ball 5-5 is arranged on the limiting spring; when the pedal stretches out, the limit steel balls are embedded into the clamping grooves 5-4 at the rear end of the sliding rail under the action of the springs; when the pedal plate is retracted, the limiting steel balls are embedded into the clamping grooves 5-3 at the front end of the sliding rail under the action of the springs. The setting of stop device has prevented that the passenger from getting on or off the bus and the footboard rocks in the vehicle travel in-process.
The invention determines the front and back positions of the pedal according to the position of the side sliding door, determines the height of the pedal according to the requirement of the primary stepping ground leaving height, and the outer edge of the pedal is approximately flush with the outer surface of the automobile body, thereby determining the position of the movable stepping mechanism, and then adjusting the shape and the size of the bracket according to the automobile body structure so as to be conveniently fixed on the automobile body.
First: the inhaul cable mechanism is provided with: as shown in fig. 5: the point A is a stay cable sleeve fixed rear bracket 3-7, the point B is a return stay cable wire rope fixed point on the side sliding door in a vehicle door closed state, the point B ' is a position of the point B after the side sliding door is completely opened, the length of B B ' is the stroke of the side sliding door, the pedal can be completely opened only when AB is more than or equal to A B ' +L on the assumption that the working stroke (namely the left and right telescopic stroke) of the movable step is L, and otherwise, the return stay cable can prevent the pedal from being continuously opened when the pedal moves to a certain position. Conversely, when A C' is more than or equal to AC+L, the pedal is not influenced to return completely by opening the inhaul cable; during assembly, the position of the rear support in the chute is fixed by adjusting the guy cable sleeve at the point A, so that a proper position meeting the conditions can be found, the locking nut 3-7-2 is loosened, the rear support is fixed in the chute in a back and forth manner relative to the advancing direction of the automobile, a proper position is found, and the nut is screwed down to lock the support.
When the side sliding door is opened, the C, B two points move from front to back along with the movement of the door, when the side sliding door moves to a certain position, the pull rope is opened to start pulling the pedal, the return pull rope is continuously retracted along with the extension of the pedal, but at the moment, the return pull rope is completely in a free state, and the movable step is completely extended according to a set stroke along with the continuous movement of the side sliding door until the side sliding door is completely opened; when the side sliding door is closed, the C, B two points return from the positions C 'and B' along with the movement of the door, when the side sliding door moves to a certain position, the return cable wire rope starts to pull the pedal, and the opening cable wire rope continuously withdraws along with the retraction of the pedal, but at the moment, the opening cable wire rope is also completely in a free state, and along with the continuous movement of the side sliding door, the movable step runs a corresponding stroke until the side sliding door is completely closed, and the movable step is completely retracted.
In order to prevent the cable wire rope from being blocked in the motion process, the cable sleeve is fixed, and the rear support is designed into a rotatable structure in the device, so that the cable sleeve can rotate along with the change of the stress direction of the cable, and the support is ensured to be consistent with the stress direction of the cable.
The design of the sliding rail structure in the invention is to ensure that the movement of the movable step is stable and light, the normal opening and closing of the side sliding door are not affected, and the pedal can not shake when a passenger gets on or off the vehicle.
The working principle of the invention is as follows: in theory, when the telescopic travel of the pedal is smaller than the working travel of the inhaul cable, the pedal can move through the working of the inhaul cable, but whether the pedal can be really realized is dependent on the actual working condition of pulling and opening the inhaul cable and returning the inhaul cable in the opening and closing process of the side sliding door; as can be seen from the analysis of fig. 5, when the three points A, B, C are in the proper positions, wherein a is the fixed rear bracket of the cable sleeve, B is the fixed point of the return cable wire rope on the vehicle door, C is the fixed point of the opening cable wire rope on the vehicle door, along with the opening of the side-pull door, when C moves to the E position, the opening cable starts to work, and the pulling pedal stretches out, at this time, the return cable is in a free state, so that the movement of the pedal is not hindered until the door is completely opened, the pedal is completely opened, and finally, the margin of L2 is remained. On the contrary, in the closing process of the side sliding door, when the position B moves to the position D, the return inhaul cable starts to work, and the pedal is pulled to retract, at the moment, the opening inhaul cable is in a free state, and the pedal cannot be hindered from moving until the door is completely opened, and the pedal is completely opened, and finally, the L1 allowance still exists, so the design of the invention can realize the design purpose.
It will be appreciated by those skilled in the art that the above-described embodiments are merely illustrative of the present invention for ease of understanding and do not limit the scope of the present invention in any way. In addition to the embodiments described above, other embodiments of the invention are possible. All technical schemes formed by equivalent substitution or equivalent transformation fall within the protection scope of the invention.
