A connecting shaft is installed on one side of the connecting arm close to the connecting window frame, and the connecting arm is movably connected to the connecting window frame through the connecting shaft, a linkage shaft is installed on one end of the connecting arm away from the connecting window frame, and the connecting arm is movably connected to the movable window through the linkage shaft, an upper movable shaft is arranged on the outside of the connecting window frame on one side of the connecting arm, upper movable arms are symmetrically movably installed on the outer wall of the connecting window frame, and one end of the upper movable arm away from the connecting window frame is movably connected to the upper movable shaft, an upper supporting arm is mounted on the surface of the upper movable shaft on one side of the upper movable arm, and the upper supporting arm is movably connected to the upper movable arm, and one end of the upper support arm away from the upper movable shaft is movably connected to the movable window. When the human body sensor does not detect the human body, the human body sensor feeds back to the controller, and the servo motor drives the driving wheel to rotate. With the cooperation of the driven wheel, the driving wheel and the driven wheel drive the belt to move. Under the sliding support of the right pulley and the slide rail, the right sliding frame is driven by the belt to move, and under the sliding support of the left pulley and the slide rail, the left sliding frame is driven by the belt to move, and the right sliding frame drives the right sliding door to move, and the left sliding frame drives the left sliding door to move, and the left sliding door and the right sliding door move towards each other to facilitate the closing of the sliding door without a lower track. When the human body sensor detects the human body, the human body sensor feeds back to the controller, and the controller operates the servo motor to rotate in the opposite direction, and the right sliding frame and the left sliding frame drive the right sliding door and the left sliding door to move in the opposite direction, so that the sliding door without a lower track can be opened, realizing the convenient human body sensing automatic control opening and closing of the hoisting sliding door without a lower track.

[0004] The technical solution disclosed in the above utility model patent document requires an external electromagnetic lock to realize the self-locking of the sliding door, thereby increasing the workload of the automatic door construction personnel. At the same time, the external electromagnetic lock can only self-lock when the sliding door is in a completely closed state, resulting in low flexibility. For example, if the sliding door needs to be opened with a gap of 10 cm for ventilation, since the sliding door is not in a completely closed state at this time, the external electromagnetic lock cannot be self-locked, and there is a risk that others will forcibly open the door manually to enter the room. For another example, if the sliding door needs to be opened with a gap of 50 cm, so that only people are allowed to pass through, and large items such as goods or carts are not allowed to pass through, since the sliding door is not in a completely closed state at this time, the external electromagnetic lock cannot be self-locked, and there is a risk that others will forcibly open the door manually to transport large items.

[0026] In one embodiment of the sliding door driving mechanism of the utility model, please refer to Figures 1 to 4. The automatic door driving motor structure is used to be arranged on an electric sliding door to automatically drive the sliding opening and closing. Specifically, the automatic door driving motor structure includes a motor 100, a housing 200 and an electromagnetic switch 300. The housing 200 is arranged at one end of the motor 100, and the main shaft 101 of the motor 100 extends into the housing 200. A limiter 400 is provided on the main shaft 101, and a limiter 401 is provided on the limiter 400. The electromagnetic switch 300 is arranged in the housing 200, and the electromagnetic switch 300 has a telescopic rod 301 extending to one side of the limiter 401. Therefore, by the telescopic rod 301 of the electromagnetic switch 300 extending to the limiter 401 and limiting the limiter 401, the rotation of the motor 100 is limited and self-locked. Specifically, after the automatic door driving motor structure of this embodiment is applied to the electric sliding door, the user can set the sliding door to open a gap of any width according to actual needs, and can achieve self-locking, specifically, setting the number of rotations of the motor 100. For example, if the sliding door needs to be opened with a gap of 10 cm for ventilation, the sliding door is controlled to stop when the width gap is 10 cm, and then the electromagnetic switch 300 is controlled to open, so that the limit part of the motor 100 can be forcibly stuck to prevent others from forcibly opening the door manually to enter the room. Similarly, it is also possible to open the sliding door with a width gap of 50 cm, so that only people are allowed to pass through, and large items such as goods or carts are not allowed to pass through.

[0027] Furthermore, the electromagnetic switch 300 is electrically connected to the control circuit of the motor 100. When the motor 100 is powered on, the electromagnetic switch 300 is powered off, so that the telescopic rod 301 retracts. When the motor 100 stops rotating, the electromagnetic switch 300 is powered on, and the telescopic rod 301 extends to the limit member 400 for limit. In addition, when the entire power is off (power failure), the electromagnetic switch 300 is powered off and retracted, so that the motor 100 can rotate under the action of external force, so that the door can be opened and closed manually.

[0028] Further, refer to Figure 4 The limiting member 400 is sleeved on a turntable on the main shaft 101 , and the limiting portion 401 is arranged on one side of the turntable.

[0029] Further, refer to Figure 3 and Figure 4, an output shaft 500 is also rotatably connected in the housing 200, one end of the output shaft 500 extends out of the housing 200 and is provided with a transmission wheel 501, and the transmission wheel 501 is used to connect the synchronous belt of the electric door. The output shaft 500 is also provided with a worm wheel 502, and the main shaft 101 is provided with a worm 102, and the worm 102 is meshed with the worm wheel 502. Specifically, the motor 100 drives the worm 102 to rotate, and the worm 102 drives the worm wheel 502 to rotate, thereby driving the output shaft 500 and the transmission wheel 501 to rotate, realizing the deceleration of the output of the motor 100 and then driving the electric door to open or close, which can increase the output torque. In addition, the worm wheel 502 and the worm 102 in this embodiment adopt a non-self-locking structure.

[0030] Further, refer to Figure 3 and Figure 5 The outer side of the housing 200 is provided with an inwardly recessed cavity, the cavity 201 is provided with a bearing 202, the worm 102 passes through the side wall of the housing 200 and extends into the bearing 202, and the end side of the housing 201 is also provided with a limit plate 210, and the limit plate 210 is provided with a pressing portion extending into the cavity 201. Specifically, when the limit plate 210 is locked on the outer side of the housing 200, the pressing portion extends into the cavity 201, pressing the bearing 202 in the cavity 201. In addition, the bearing 202 is installed into the cavity 201 from the outer side of the housing 200, which facilitates the installation of the bearing 202.

[0031] Further, refer to Figure 3 and Figure 5 The motor 100 is further provided with a positioning hole 103 on the end side, and the housing 200 is further provided with a positioning pin 203 on the end side, and the positioning pin 203 is positioned in the positioning hole 103 .

[0032] Further, refer to Figure 1 and Figure 2 A support plate 220 is provided on the end side of the housing 200 and the outer end side of the motor 100 , and the support plate 220 is used for installing the motor 100 and the housing 200 .

[0033] Further, refer to Figure 1 and Figure 2 The support plate 220 is L-shaped, and a clamping plate 230 is provided on the bottom side of the support plate 220. The support plate 220 and the clamping plate 230 are connected by a screw 240, so that the clamping plate 230 and the support plate 220 form a clamping position 203 for clamping in the guide rail box of the electric sliding door. The clamping method is used for fixed installation, which is easy to adjust and does not require drilling holes on the guide rail box, which is convenient for installation.
