Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

The utility model provides an automatic door opening and closing mechanism, the structure shown in Fig. 1 and Fig. 2, the automatic opening and closing door runs smoothly and has high safety.

The automatic door opening and closing mechanism shown in Figure 1 and Figure 2 includes a support plate 1 and a flexible shaft 2 positioned on the support plate 1, a transmission mechanism, a rocker mechanism one 3 and a rocker mechanism two 4 that are oppositely arranged, and the rocker mechanism The first 3 and the rocker mechanism two 4 are respectively connected with the door panel one 7 and the door panel two 8 through the connecting plate one 5 and the connecting plate two 6, the rocker arm mechanism one 3 and the rocker arm mechanism two 4 are crank structures, and one end of the crank is hinged On the support plate 1, the other ends are respectively hinged on the first connecting plate 5 and the second connecting plate 6.

The transmission mechanism includes a main transmission mechanism 15, a primary transmission mechanism 12 and a secondary transmission mechanism 13. One end of the flexible shaft 2 is hinged with one end of the main transmission mechanism 15, and the middle part of the flexible shaft 2 is installed on the support plate 1 through a flexible shaft fixing frame 16. The main transmission mechanism 15 is a bending rod structure, one end of the bending rod is connected with the flexible shaft 2, the middle part of the bending rod is hinged on the support plate 1, and the other end of the bending rod is hinged with the primary transmission rod 10. The support plate 1 is also provided with a dead point limiter 9, and the primary transmission rod 10 is connected with a limit plate 17. When the door panel 1 7 and the door panel 2 8 are closed, the limit plate 17 snaps into the dead point limiter 9 .

The primary transmission mechanism 12 links to each other with the main transmission mechanism 15 by the primary transmission rod 10, the secondary transmission mechanism 13 links to each other with the primary transmission rod 10 by the secondary transmission rod 11, and the primary transmission mechanism 12 links to each other with the connection plate 26, and the secondary transmission mechanism 13 links to each other with the primary transmission rod 10. Stage transmission mechanism 13 links to each other with connecting plate one 5. One end of the primary transmission mechanism 12 is connected with the primary transmission rod 10 , the other end is connected with the connecting plate 2 6 , and the middle part is hinged on the supporting plate 1 . One end of the secondary transmission mechanism 13 is hinged on the support plate 1, the other end is connected with the connecting plate one 5, and the middle part is connected with the secondary transmission rod 11.

A spring 14 is installed on the primary transmission rod 10, and the preloading force of the spring 14 can be adjusted. During the opening and closing process of the door panel, the spring 14 can be compressed to different degrees.

The specific working principle is as follows:

As shown in Figure 1, this mechanism is in an open state. If it needs to be closed, a force needs to be applied to one end of the flexible shaft 2 to make the main transmission mechanism 15 rotate counterclockwise, thereby pushing the primary transmission rod 10 to move, and the primary transmission rod 10 pushes a The first-stage transmission mechanism 12 rotates counterclockwise, and pulls the door panel 2 8 to move to the left. Pull the door panel to move to the right. When the three points A, B, and C in the figure are on a straight line, the spring 14 on the primary transmission rod 10 has the largest amount of compression, which is called the "dead point" at this time. After turning over the "dead point", the primary The limiting plate 17 on the transmission rod 10 can enter the dead point limiter 9, and the door panel will be firmly locked.

As shown in Figure 2, this mechanism is in a closed state. If it needs to be opened, a force needs to be applied to one end of the flexible shaft 2 to make the main transmission mechanism 15 rotate clockwise, thereby pushing the primary transmission rod 10 to move. When A and B in the figure When the three points of C and C are on a straight line, the compression amount of the spring 14 on the first-stage transmission rod 10 is the largest, which is now called "dead point"; Disengage from the device 9, then the primary transmission rod 10 pulls the primary transmission mechanism 12 to rotate clockwise, and pulls the door panel 2 8 to move to the right; meanwhile, the primary transmission rod 10 will also push the secondary transmission rod 11 to move, and the secondary transmission rod 11 will promote the secondary transmission mechanism 13 to rotate counterclockwise, thereby promoting the door panel to move to the left, and the door is opened.

The automatic door opening and closing mechanism provided by the utility model is composed of a support plate, a flexible shaft located on the support plate, a transmission mechanism, and a rocker mechanism 1 and a rocker mechanism 2 that are relatively arranged. The connecting plate then drives the switch of the door panel. The rocker mechanism 1 and rocker mechanism 2 make the switch of the door panel more stable, and the reliability is higher when the door panel is opened and closed. The setting of the limit plate and the dead point limiter can ensure that the door panel It can be self-locked when closed to prevent tourists from opening the door from the inside, which is more secure.

The above description of the disclosed embodiments enables those skilled in the art to realize or use the utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
