The upper inner door 3 is fixed at a position opposite to the second slide groove 2 in the upper door frame. The second slide groove 2 is opposite to the sixth slide groove (not shown). Stainless steel slide groove baffles are welded at the lower ends of the second slide groove 2 and the sixth slide groove (not shown). Gaps are formed between the two side edges of the upper inner door 3 and the two side frame bars of the upper door frame. The two sides of the upper outer door 6 are embedded in the two first slide grooves 1 and can slide in the first slide grooves 1 relative to the upper inner door 3; a rectangular stainless steel first slider 18 is embedded in the second slide groove 2 and the sixth slide groove (not shown), and a first fixing bracket 5 is provided on the lower side of the first slider 18. The first fixing bracket 5 is a pair of parallel protrusions fixed to the lower side of the first slider 18, and a first through hole is provided on the top of each protrusion.

[0021] The bottom of the first pneumatic rod 7 is installed on a second fixed bracket 20 fixed on the two sides of the door frame. The second fixed bracket 20 is provided with a rotating shaft 19 perpendicular to the side frames of the door frame. The bottom of the first pneumatic rod 7 is sleeved on the rotating shaft 19 and can rotate along the rotating shaft 19; a second through hole is provided at the top of the first pneumatic rod 7. The first through hole and the second through hole have the same aperture. When they overlap, the first connecting member 4 can be inserted for connection. The first connecting member 4 is a bolt and a matching nut.

[0022] A third stainless steel connecting rod 17 is vertically arranged on the surface just above the above-mentioned gap at both ends of the top of the upper outer door 6 , and the third connecting rod 17 is welded to the upper side surface of the first sliding block 18 .

[0023] The lower door includes a lower inner door 28 and a lower outer door 11. The lower outer door 11 is a double-opening door. Two third sliding grooves 16 are arranged in parallel and penetrate the door panel of each lower outer door 11. One end of the third sliding groove 16 is opened at the side of the door frame. The third sliding groove 16 is a bulged shape at the bottom of the groove. A cylindrical stainless steel second sliding block 35 is embedded in the third sliding groove 16. The two end surfaces of the second sliding block 35 face the width direction of the groove bottom and are stuck in the groove bottom and will not fall out from the groove top. A small stainless steel ring is sleeved on the second sliding block 35.

[0024] Two fourth slide grooves 12 are arranged at positions corresponding to the two third slide grooves 16 on the outer walls of both sides of the door opening, and two fifth slide grooves 9 are also arranged parallel to the fourth slide grooves 12. The two fourth slide grooves 12 are located between the two fifth slide grooves 9. The fifth slide groove 9 is in the shape of an enlarged groove bottom. A cylindrical stainless steel third slider 15 is arranged in the fifth slide groove 9. The two end surfaces of the third slider 15 face the width direction of the groove bottom and are stuck in the groove bottom and will not fall out from the groove top. The fourth slide groove 12 and the fifth slide groove 9 are both opened at one end to the side frame of the door opening frame, and the length of the fifth slide groove 9 is based on the ability of the lower outer door 11 to be fully opened.

[0025] A rotating rod 8 driven by a door pump 33 is arranged perpendicular to the fourth slide groove 12 at the end of the fourth slide groove 12 away from the door opening on the outer wall of the vehicle. A stainless steel first connecting rod 10 is vertically fixed on the rotating rod 8. Specifically, the first connecting rod 10 is fastened to the rotating rod 8 through a second connecting member 14 arranged at one end thereof, and the second connecting member 14 is a clamp. The other end of the first connecting rod 10 is welded to a small ring sleeved on the second slider 35.

[0026] A stainless steel second connecting rod 13 is fixedly provided at a position on the lower outer door 11 corresponding to the fifth sliding groove 9 , and the other end of the second connecting rod 13 is welded to the third sliding block 15 .

[0027] The lower inner door 28 is a one-piece type, and its opening, closing and lifting are controlled by a motor system. The motor system includes a stainless steel motor bracket 23 connected in sequence and arranged on the inner wall of the vehicle on both sides of the door opening, a first motor 26 arranged on the motor bracket 23, a vertical screw rod 27 arranged at the output end of the first motor 26, a screw nut 34 connected to the screw rod 27, a stainless steel door-shaped gear shaft bracket 29 fixed on the screw nut 34, a second motor 31 arranged on the inner wall of the gear shaft bracket 29 on the side of the screw nut 34, a gear 32 connected to the output end of the second motor 31, and a gear shaft 30 meshing with the gear 32. The gear shaft 30 extends out of the other side wall of the gear shaft bracket 29 and the extended end is welded to the lower inner door 28.

[0028] Blind holes 36 are respectively provided at both ends of the two side edges of the lower inner door 28 opposite to the two side walls of the door hole frame, a stainless steel gas pressure rod bracket 24 is provided on the inner wall of the vehicle corresponding to each blind hole 36, and a second gas pressure rod 25 whose end matches the blind hole 36 is provided on the gas pressure rod bracket 24.

[0029] In specific use, when the door is opened, the first gas pressure rod 7 rotates outward and extends upward, driving the connected first slide block 18 to slide along the first slide slot 1 toward the lower end of the upper door, and lifting the hinged upper inner door 3 outward and upward. At the same time, since the first gas pressure rod 7 is also fixedly connected to the upper outer door 6 through the first slide block 18, the upper outer door 6 slides along the upper inner door 3. When the upper door is raised to a horizontal level, the operation of the first gas pressure rod 7 is stopped to fix the upper door.

[0030] When the upper door is opened, the second pneumatic rod 25 retracts from the blind hole 36, and the door pump 33 drives the rotating rod 8 to rotate in such a way that the lower outer door 11 is opened outward, thereby driving the fixed first connecting rod 10 to rotate. The first connecting rod 10 drives the second slider 35 to slide from the E end to the F end of the third slide groove 16 of the lower outer door 11. At the same time, the second connecting rod 13 drives the third slider 15 to slide from the D end to the C end in the fifth slide groove 9, thereby opening the lower outer door 11.

[0031] When the lower outer door 11 is opened, the first motor 26 drives the screw rod 27 to rotate in a manner of lowering the height of the lower inner door 28, thereby driving the screw rod nut 34 to rise and fall to lower the height of the lower inner door 28. At the same time, the second motor 31 drives the gear 32 to operate in a manner of rotating the lower inner door 28 outward. The gear 32 drives the gear shaft 30 to rotate, thereby expanding the lower inner door 28 fixedly connected to the gear shaft 30 outward. When the lower end of the lower inner door 28 contacts the bottom surface, the operation of the first motor 26 and the second motor 31 is stopped to fix the lower inner door 28.

[0032] The process of closing the bus door is opposite to the above-mentioned opening process and will not be described in detail here.

[0033] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and details may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
