[0030] See also Figures 1 to 5 In the specific embodiment shown, the utility model discloses an automatic door opening device, comprising: a front cabin body 10, a rear cabin body 20 and a door opening mechanism 30, one end of the door opening mechanism 30 is connected to the front cabin body 10, and the other end is connected to the rear cabin body 20, the front cabin body 10 and the rear cabin body 20 are movably connected, and the door opening mechanism 30 works to drive the front cabin body 10 to rotate around the rear cabin body 20, so that an open or closed state is formed between the front cabin body 10 and the rear cabin body 20.

[0031] Specifically, the front cabin body 10 and the rear cabin body 20 are movably connected, and then the door opening mechanism 30 works to drive the front cabin body 10 to rotate around the rear cabin body 20, so that an open or closed state is formed between the front cabin body 10 and the rear cabin body 20, thereby realizing automatic opening and closing of the door, thereby improving the convenience and efficiency of door use; in addition, the door opening device has a simple structure, is easy to maintain and has a low maintenance cost; in addition, the automatic opening and closing of the door reduces the need for manual operation, saves human resource costs, and can avoid accidental injuries that may occur during manual operation, providing a safer door control method; in addition, for some special places, such as hospitals, shopping malls, office buildings, etc., the automatic door opening device can facilitate the entry and exit of pedestrians or those carrying items, and provide a better barrier-free passage experience.

[0032] In one embodiment, the door opening mechanism 30 includes a reduction motor 31, a transmission assembly, a front cabin connecting rod 32 and a pin shaft seat 33. The reduction motor 31 is installed on the rear cabin body 20, one end of the transmission assembly is connected to the reduction motor 31, and the other end is connected to the front cabin connecting rod 32. The front cabin connecting rod 32 is connected to the pin shaft seat 33 at one end away from the transmission assembly, and the pin shaft seat 33 is fixed to the front cabin body 10. The reduction motor 31 drives the transmission assembly to move when it works, so that the front cabin connecting rod 32 moves and drives the front cabin body 10 to rotate around the rear cabin body 20.

[0033] Specifically, through the cooperation of the reduction motor 31 and the transmission assembly, the automatic opening and closing function of the door is realized, providing a convenient user experience; in addition, the reduction motor 31 drives the transmission assembly to achieve smooth movement of the door body and avoid vibration or noise caused by uneven force; in addition, due to the use of the door opening mechanism 30, the space required for opening the door can be reduced, which is particularly suitable for places with limited space; in addition, the door opening mechanism 30 can increase the opening and closing speed of the door and improve the traffic efficiency, which is particularly suitable for places that require quick passage.

[0034] In one embodiment, the transmission assembly includes a short connecting rod 34, a long connecting rod 35 and a connecting block 36, one end of the short connecting rod 34 is connected to the reduction motor 31, and the other end is hinged to the long connecting rod 35, one end of the connecting block 36 is hinged to one end of the long connecting rod 35 away from the short connecting rod 34, and the other end is hinged to the front cabin connecting rod 32.

[0035] Specifically, the length of the long connecting rod 35 is much larger than that of the short connecting rod 34. The short connecting rod 34, the long connecting rod 35 and the connecting block 36 constitute a crank slider structure. The rotational motion output by the reduction motor 31 is converted into the linear motion of the connecting block 36 via the above-mentioned crank slider structure; in addition, through the design of the short connecting rod 34, the long connecting rod 35 and the connecting block 36, continuous motion transmission can be achieved to ensure the smooth movement of the door body.

[0036] In one embodiment, the connecting block 36 is further provided with a protruding end 361 at one end away from the long connecting rod 35 , and the rear cabin body 20 is provided with a limiting buffer block 21 corresponding to the protruding end 361 .

[0037] Specifically, the limit buffer block 21 is fixed to one side end of the rear cabin body 20. When the reduction motor 31 drives the connecting block 36 to move to the limited position, the limit buffer block 21 can prevent the connecting block 36 from continuing to move, thereby preventing the connecting block 36 from exceeding the limited position.

[0038] In one embodiment, the connecting block 36 is further connected to a sliding block 37 , and the rear cabin body 20 is provided with a guide rail 38 corresponding to the sliding block 37 .

[0039] Specifically, the slider 37 is installed at the bottom of the connecting block 36, and the slider 37 slides laterally along the guide rail 38 to ensure that the slider 37 moves along the set track direction during the opening and closing process to maintain the stability and balance of the door; in addition, through the design of the connecting block 36, the slider 37 and the guide rail 38, the stability of the entire door opening mechanism 30 can be enhanced to ensure that the door body will not shake or misalign during movement, thereby improving the safety of the door.

[0040] In one embodiment, the front cabin body 10 is further provided with an unlocking mechanism 40 , and the unlocking mechanism 40 cooperates with the front cabin connecting rod 32 and the pin shaft seat 33 .

[0041] Specifically, when the door cannot be opened automatically due to a malfunction or power failure, the unlocking mechanism 40 can be operated to separate the front cabin connecting rod 32 from the pin shaft seat 33 so as to manually open the front cabin body 10 .

[0042] See also Figures 4 to 5 As shown, in one embodiment, the unlocking mechanism 40 includes a latch seat 41, a latch pin 42, a pin shaft 43 and a tension spring 44. The latch seat 41 is fixed to the pin shaft seat 33. The latch pin 42 is T-shaped and includes a transverse portion and a vertical portion. One end of the transverse portion is hinged to the latch seat 41, and the other end is an operating end. One end of the tension spring 44 is connected to the operating end, and the other end is connected to the pin shaft seat 33. The pin shaft 43 is laterally inserted into the pin shaft seat 33 and the front cabin connecting rod 32 so that the pin shaft seat 33 is hinged to the front cabin connecting rod 32. The vertical portion extends into the pin shaft seat 33 and cooperates with the pin shaft 43 to form a locking fit.

[0043] Specifically, under the tension of the tension spring 44 , the vertical portion extends into the hole opened at the corresponding position of the pin shaft seat 33 , and then cooperates with the pin shaft 43 to form a locking fit.

[0044] In one embodiment, the pin shaft 43 is provided with an open slot 431 , and the vertical portion cooperates with the open slot 431 .

[0045] Specifically, the width of the opening slot 431 is slightly larger than the thickness of the vertical portion, so as to facilitate the insertion of the vertical portion. In addition, the insertion end of the pin shaft 43 is a conical end, so as to facilitate the installation or removal of the pin shaft 43.

[0046] In one embodiment, the operating end is provided with a cap 45 . The design of the cap 45 can make the operating end more comfortable and easier to hold, thereby improving the comfort of operation and reducing the discomfort caused by direct contact with components.

[0047] In one embodiment, the front cabin body 10 and the rear cabin body 20 are connected by a hinge 50, which can improve the overall stability and accuracy of the door and save space.

[0048] When the front cabin body 10 needs to be closed, the output shaft of the reduction motor 31 rotates clockwise to drive the connecting block 36 to move forward a certain distance, driving one end of the front cabin connecting rod 32 hinged thereto to move, and the other end of the front cabin connecting rod 32 drives the pin shaft seat 33 hinged thereto and the front cabin body 10 fixedly connected to the pin shaft seat 33 to rotate clockwise around the hinge 50, so that the front cabin body 10 is in a closed state. Since the position of the limit buffer block 21 is the limit position for the forward movement of the connecting block 36, at this time, the front cabin connecting rod 32 forms a small angle (for example: 2-8°) with the vertical direction to tighten the front cabin body 10, that is, to achieve mechanical self-locking (at this time, the user can no longer push the front cabin body 10 to rotate).

[0049] When the front cabin body 10 needs to be opened, the output shaft of the reduction motor 31 rotates counterclockwise to drive the connecting block 36 to move backward a certain distance, driving one end of the front cabin connecting rod 32 hinged thereto to move, and the other end of the front cabin connecting rod 32 drives the pin shaft seat 33 hinged thereto and the front cabin body 10 fixedly connected to the pin shaft seat 33 to rotate counterclockwise around the hinge 50 shaft, and the front cabin body 10 opens.

[0050] When the door cannot be opened automatically due to a fault or power failure, the latch 42 can be manually lifted, and the pin 43 can be pulled out. At this time, the front cabin connecting rod 32 is separated from the pin seat 33, and the front cabin body 10 fixedly connected to the pin seat 33 can be manually pulled counterclockwise to open. When the automatic door opening function needs to be restored, it is only necessary to lift the latch 42, insert the pin 43 back to its original position, and then release the latch 42, so that the vertical part can extend into the opening groove 431 of the pin 43 to prevent the pin 43 from sliding left and right; the tension spring 44 locks the latch 42 on the pin seat 33 to prevent the vertical part of the latch 42 from being separated from the opening groove 431 due to vibration during operation, so that the pin 43 is loose and slides out, causing the door opening mechanism 30 to fail and the front cabin body 10 to open automatically.

[0051] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
