The sliding door body 2 and the fixed door body 1 are half-height doors, and are more suitable for outdoor meeting places, outdoor platforms, ground and other installation places, and the use scenes of the double-opening sliding door are described by combining the practical situation as follows:

application to scenes using indoor electric partitions: at present, advertising boards are hoisted indoors or movable showing stands are built, an indoor electric partition is needed, a fixed rail and a motor are needed to be installed on a ceiling of the existing indoor electric partition, a group of suspension brackets are driven by the motor to move along the rail, the rail and the motor are needed to be shielded by a ceiling or a wall decorative interlayer after an electric door moving mechanism (a sliding door) is additionally installed on the ceiling and the wall, if the existing electric door moving mechanism is additionally installed on the ground, the rail and the motor cannot be hidden in a mode of raising the ground height of the whole floor, deep grooves cannot be excavated for the installation of the electric partition, and the grooves can damage the floor structure; however, if the double-opening sliding door of the present invention is adopted, since the second box 7 only includes the mechanical structures such as the guide rail 4, the slider 3, the driven wheel 531 and the steering wheel 533, and does not include the motor 51, the supporting electrical equipment and the cable, the whole structure volume contained in the second box 7 can be designed to be small, especially the whole height of the second box 7 can be reduced to be less than the shortest side length of the motor 51, therefore, the mechanical structure can be directly installed on the ground, the height difference with the ground is small, no installation groove needs to be dug on the ground, and thick carpets can be laid on the two sides raised after the ground is installed, so that the laying height of the carpets on the two sides is close to the height of the second box 7 to achieve the ground leveling effect after the decoration. In addition, the transmission extension belt 532, the first box body 6 and the like can be arranged outside the integral mechanical structure which is installed on the ground, the electrical equipment can be installed in an interlayer of a peripheral upright post or a wall body, and can also be installed in an electrical room which is hidden, the electrical equipment and the mechanical structure are connected through the transmission extension belt 532 and transmit the door moving action, the transmission extension belt 532 can be covered and protected by a ground wiring housing, a decoration carpet or floor tile can leave a gap for the wiring housing, and can also be directly laid on the housing, and more decoration modes can be determined by field requirements. Therefore, the double-opening sliding door is suitable for outdoor meeting places without depending on ceilings and walls, hotel lobbies with overhigh ceilings, dome type exhibition halls or scenes with narrow ceiling installation space and difficult installation.

The method is applied to scenes of high-speed rail platforms: the existing high-speed railway platform is almost not provided with an electric door moving mechanism, because the secondary reconstruction is generally carried out on the platform of the established high-speed railway (a train, a motor train, a maglev train or other trains equipped with similar waiting platforms), the electric door moving mechanism similar to the existing subway platform door is additionally arranged to play a practical effect similar to that of the subway platform door, the depth of the ground decoration surface of the existing high-speed railway platform is less than 100mm, the track and the motor of the high-speed railway platform door must be buried in the ground digging groove with the limited height, the current electric door moving mechanism only simply considers that the depth of the motor, the upper and lower supports thereof and a layer of step plate which is flush with the ground exceeds 100mm, so that the installation is difficult, and if the installation is required, the steel bar structure layer of the platform needs to be excavated downwards after the decorative surface of 100mm is excavated until the installation height of the electric door moving mechanism is met. The platform structure is damaged, potential safety hazards are left, and the platform structure layer is still damaged a little even if a more expensive linear motor is adopted to reduce the height required by installation; if the motor is considered to be placed in the sliding door body or fixed doors on two sides of the sliding door body, although the motor does not need to be buried underground, the motor can move along with the door body when being placed in the sliding door body, more cost needs to be added for arranging a wire dragging structure for a wire connected with the motor or providing wireless communication to control the motor, the train can be stopped inaccurately when being placed in the fixed doors, and a traffic accident that the vehicle door is not aligned with the movable doors and is aligned with the fixed structures on two sides often occurs; however, if the double-opening sliding door of the present invention is adopted, the second box 7 only includes the guide rail 4, the slider 3, the driven wheel 531, the steering wheel 533, and other mechanical structures, and does not include the motor 51, the supporting electrical equipment, and the cable, so the whole structure volume contained in the second box 7 can be designed to be small, especially the whole height of the second box 7 can be reduced to be lower than the shortest side length of the motor 51, therefore, the mechanical structure can be directly installed in the 100mm ground opening groove, and after the installation, the top of the second box 7 is flush with the finishing surface of the platform. In addition, the transmission extension belt 532 and the first box 6 may be installed in a whole mechanical structure installed in a floor, or the electric devices may be installed in a hidden electric room, or may be installed in a sandwich of a peripheral column or a wall, and the electric devices and the mechanical structure are connected by the transmission extension belt 532 to transmit a door moving motion. Therefore, the double-open sliding door is suitable for the high-speed rail platform 10, mechanical structures such as the first box body 6 and the like can be installed in the shallow groove, only the decoration surface and the sandy soil layer of the platform 10 are dug, the solid concrete structure is not damaged, the construction cost can be reduced, and the structural risk of excessive reconstruction of civil engineering is avoided.

In summary, the present invention can arrange the motor outside the platform through the conveying extension belt, when the motor drives the driving wheel to rotate, the conveying extension belt drives the two sliding door bodies to slide oppositely, thereby closing the door is realized, and when the motor rotates reversely, the sliding door bodies are driven to slide towards the other side, so as to realize opening the door, i.e. the electrical equipment (motor) is separated from the mechanical structure, the arrangement space of the electrical equipment separated from the main body mechanism is looser, the maintenance is convenient, the height of the mechanical part of the sliding door in the prior art can be reduced, the sliding door can be installed in a sticking manner without digging a groove on the ground, the sliding door is suitable for a narrow installation space, the sliding door can be installed on a uniform and flat ground, the independent customized design for the fluctuation of the ceiling is not needed, the standardized and modularized design and production scheme can be adopted, the design period is shortened, the production cost is reduced, and the problem of insulation of the door bodies is completely eliminated.
