[0002] like Figure 1 The figure shows the connection structure between the articulated canopy gangway and the vehicle body of a bus in the prior art. The "L"-shaped profile B is fixed to the vehicle body A with rivets or self-tapping screws. When installing the articulated canopy, first install the outer canopy rubber strip C on the folding canopy wire rope D. Then, place the rubber strip C and wire rope D together into the groove of the "L"-shaped profile B. Use a rubber hammer and plastic spacers to knock them into place. Finally, tighten the wire rope joint nut at the bottom to tighten the wire rope.

[0003] This structure requires tapping the rubber strip along a full circle during installation, and can only be operated on the outside of the gangway, so it is necessary to climb to the top of the building.

[0032] like Figure 2 As shown, the profile 1 is a C profile, and the profile 1 is fixedly connected to the vehicle body by rivets or self-tapping screws;

[0033] like Figure 3 As shown, the cross-section of the base 2 is set to be "n"-shaped or "J"-shaped, and the base 2 is fixedly connected to the vehicle body by welding or riveting. A through hole 21 for the bolt 4 to pass through is opened inside the base 2, and limiting holes 22 for the limiting pin 9 to pass through are opened on both sides of the through hole 21.

[0034] A bellows 8 is fixed on the other side of the profile 1, and a sealing strip 3 is filled between the profile 1 and the bellows 8. The sealing strip 3 is glued on one side. After tearing off the adhesive back during installation, the adhesive side of the sealing strip 3 is facing the inside of the profile 1 and glued to the inner wall of the profile 1. A protrusion is provided on the side of the sealing strip 3 close to the bellows 8 to enhance the sealing performance when it is tightly attached to the bellows 8. A groove is provided on the side of the sealing strip 3 close to the profile 1 to avoid rivets or self-tapping screws used when installing the profile to ensure that the strip is tightly attached to the profile 1 when it is pasted.

[0035] A pressing plate 5 is provided on the side of the base 2 and the bellows 8 away from the vehicle body. A bolt 4 and a limit pin 9 are passed through one end of the pressing plate 5 and the inside of the base 2 , and the other end of the pressing plate 5 presses the bellows 8 tightly.

[0036] like Figure 4 As shown, the bolt 4 in this embodiment is configured to include a screw neck 41 that cooperates with the pressure plate 5 and is configured to be square. The purpose of this configuration is that when the bolt 4 is rotated, the pressure plate 5 that cooperates with it can rotate synchronously with the bolt 4 as the center of the circle; a pin hole 42 is opened at the tail of the screw for the cotter pin 11 to pass through.

[0037] Correspondingly, if Figure 5 As shown, one end of the pressure plate 5 is provided with a square hole 51 that cooperates with the screw neck 41 for the bolt 4 to pass through, and one end of the pressure plate 5 is also provided with a round hole 52 that cooperates with the limit pin 9. The limit pin 9 in this embodiment is a quick-release pin, and the limit pin can be installed and removed by pressing the end button of the limit pin 9. The other end of the pressure plate 5 is provided with an inclination angle 53 to facilitate the pressure plate 5 to gradually press the bellows 8 during the rotation process.

[0038] like Figure 1As shown, the outer periphery of the tail protruding end of the bolt 4 toward the inside of the base 2 is threadedly connected with a nut 10, and the nut 10 is a hexagonal nut. A slot for accommodating a cotter pin 11 is provided on the outer periphery of the nut 10, and a cotter pin 11 is passed through the inside of the slot. After the nut 10 is tightened, the cotter pin 11 is inserted into the pin hole 42 to limit the nut 10, thereby ensuring that the clamping force of the pressure plate 5 on the folding shed 8 does not change.

[0039] The bellows 8 in this embodiment includes a fixed profile 6 and a bellows frame 7. Figure 1 As shown, the fixing profile 6 is tightly fitted with the sealing strip 3 under the pressing action of the pressing plate 5, and the bellows frame 7 is arranged on the side of the fixing profile 6 away from the sealing strip 3, and is connected to the fixing profile 6 by rivets and sealed with sealant.

During installation, multiple connecting structures are arranged around the profile 1 and arranged according to Figure 2 The first installation is completed as shown. Figure 6 The circled part is an enlarged view of the structure at position I.

[0041] When the vehicle is uncoupled, press the button on the head of the limit pin 9 to remove the limit pin 9, and use a wrench to rotate the head of the bolt 4 90° clockwise to drive the pressure plate 5 to rotate 90° synchronously. Rotate all the pressure plates in this way to separate the folding shed 8 from the vehicle body, completing the uncoupling of the articulated shed and the vehicle body.

[0042] When reassembling the vehicle, first place the bellows 8 in the designated position, use a wrench to rotate the head of the bolt 4 90° counterclockwise, driving the pressure plate 5 to rotate 90° synchronously, and rotate all the pressure plates 5 counterclockwise in this step to align the circular hole 52 of the pressure plate 5 with the limit hole 22 of the base 2, and insert the limit pin 9 to complete the limit lock, so that the bellows 8 and the vehicle body are installed and the reassembly of the articulated shed and the vehicle body is completed.

[0043] The utility model provides a vehicle gangway connection structure, which can quickly complete the installation and disassembly of the articulated shed and the vehicle body, and has the characteristics of simple, quick and safe operation; it can be flexibly used in the connection between the gangways and the vehicle bodies of various buses, trams, BRTs, etc., and has a wide range of applications; the decoupling and recoupling of the vehicle and the articulated shed are all performed inside the articulated shed, and there is no need to climb to the top of the shed, which can effectively solve the problem of repeated climbing to the top during the decoupling and recoupling of the vehicle and the gangway, which is time-consuming and has potential safety hazards. It can quickly complete the decoupling and recoupling of the gangway and the vehicle body, saving time and effort and ensuring safety.
