Electric swing doors are mainly composed of a door body, a drive motor, a slideway, and a control system. The door row and the fixed column of the current swing door are connected by hinges. When the sliding door passes over an uneven ground, the roller has poor contact with the ground, which is easy to cause warping, poor fit, and easy vibration, resulting in unstable movement.

When the casement door leaf is rotated to open and encounters an uneven road surface, the lower end of the casement door leaf contacts the spherical fulcrum of the fixed column, and the upper end of the casement door leaf is movably arranged in the fixed column. The casement door leaf can swing around the spherical surface of the support shaft, so that the casement door body can rise and fall with the ground and always keep in contact with the ground, which can effectively alleviate the shaking degree of the casement door body, make the casement door body more stable during rotation, and improve the movement stability and safety factor.

[0010] Furthermore, the swing cantilever door also includes a driving wheel device, and the driving wheel device includes a swing drive mechanism and a plurality of driving wheels.

The diameter of the hemispherical portion is equal to the diameter of the cylindrical portion, and both are larger than the diameter of the spherical portion of the support shaft. When the road surface is uneven, the swing door body can rise and fall with the ground and maintain contact with the ground, thereby improving the smoothness of movement and the safety factor.

[0014] Furthermore, a cover and an upper fulcrum shaft are provided at the upper end of the fixing column; the upper end of the upper fulcrum shaft is screwed to the cover. The slot block is provided at the upper end of the support frame and is located below the upper fulcrum shaft. An adjustment slot is provided on the slot block, the length direction of the adjustment slot is consistent with the length direction of the casement door body, and the lower end of the upper fulcrum shaft is movably provided in the adjustment slot. The upper side of the casement door body is buffered and limited by the slot, which effectively adapts to the uneven road surface and improves compatibility and stability.

[0015] Furthermore, the sliding door leaf comprises a sliding door body and a lifting and adjusting mechanism, wherein the lifting and adjusting mechanism is provided at the lower end of the sliding door body away from the connecting column, and the lifting and adjusting mechanism is used to adjust the height of the sliding door body from the ground. The height of the sliding door leaf from the ground can be adjusted according to the on-site road conditions, thereby improving the efficiency of assembly and debugging.

The driving wheels 52 on both sides are arranged one by one, and the distances between the two corresponding driving wheels 52 on both sides and the support shaft 73 are arranged to be the same, so that the two driving wheels 52 run coaxially and on the same track, so that the driving wheels 52 can grip the ground more firmly and more stably. At least one axle 53 is arranged on each side, and the axle 53 is used to connect the plurality of driving wheels 52 on the same side. The horizontal opening driving mechanism 51 is used to drive the plurality of axles 53 to drive the plurality of driving wheels 52 to rotate at the same time, so as to improve the stability of the horizontal opening door leaf 4. The running speeds of the driving wheels 52 on the same side are set differently, and the coaxial differential operation is carried out, so that each driving wheel 52 can keep synchronous rotation and keep the relative position stable, so that the driving wheel 52 can grip the ground more stably.

The end of the swing door leaf 4 that was originally close to the sliding groove 21 moves to one side of the fixed column 7. In addition, the two sets of rollers 324 of the sliding door leaf 3 are naturally set off the ground, which reduces the friction resistance when the swing door leaf 4 rotates to one side, and improves the efficiency and stability of the rotation. Please refer to Fig.15 When the door needs to be in a fully open state, the casement driving mechanism 51 drives the four driving wheels 52 to rotate, so that the casement door body 42, the connecting column 2 and the sliding door leaf 3 rotate as a whole around the support shaft 73 of the fixed column 7.
