[0035] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the convenience of description, only parts related to the present invention rather than all structures are shown in the drawings.

[0036] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature.

[0038] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] This embodiment provides an automatic door opening and closing device, as Figures 1-5 shown. The automatic door opening and closing device includes a support mechanism 10, a door body assembly 20, and a driving mechanism 30; the support mechanism 10 is arranged on a support surface, and a doorway 11 is provided in the middle of the support mechanism 10; the door body assembly 20 includes a first door body 21 and a second door body 22, and the first door body 21 and the second door body 22 are respectively pivotally connected to two ends of the support mechanism 10 along the length direction, and the door body assembly 20 can open and close the doorway 11; the driving mechanism 30 is arranged at the bottom end of the support mechanism 10, and the driving mechanism 30 includes a first driving component 31 and a second driving component 32. The output end of the first driving component 31 is in transmission connection with the first door body 21, and the output end of the second driving component 32 is in transmission connection with the second door body 22. The first driving component 31 and the second driving component 32 can respectively drive the first door body 21 and the second door body 22 to move in a direction away from or close to the doorway 11 so as to be able to automatically open and close the doorway 11.

[0040] In this device, the first driving component 31 and the second driving component 32 can respectively drive the first door body 21 and the second door body 22 to move. It not only has a simple structure, but also can force the first door body 21 and the second door body 22 to close the doorway 11 during the laser cutting process, thereby reducing unnecessary shutdown of the equipment caused by manual accidental door opening, and at the same time improving the safety of the operators and the production efficiency of the equipment.

[0041] It should be noted that in this embodiment, the automatic door opening and closing is applied to a laser cutting device. Since manual opening and closing of the door body by the operator is prohibited during the laser cutting process, this device can well solve this problem, ensure the safety of the operator, and at the same time improve the user experience and aesthetics. In other embodiments, this automatic door opening and closing can also be applied to other devices without specific limitation on the scope of use.

[0042] Furthermore, as Figure 2 shown, the support mechanism 10 includes a first support rod 12, a second support rod 13, a cross bar 14 and a base 15. The first support rod 12 and the second support rod 13 are arranged on both sides of the base 15. The cross bar 14 is located at the top of the first support rod 12 and the second support rod 13 and is used to connect the first support rod 12 and the second support rod 13. The first support rod 12, the second support rod 13, the cross bar 14 and the base 15 together enclose a doorway 11. In addition, the cross bar 14 and the first support rod 12 are pivotally connected through a pivot block 23, and the other end of the pivot block 23 is pivotally connected to a pivot seat 24, and the pivot seat 24 is connected to the first door body 21; similarly, the cross bar 14 and the second support rod 13 are pivotally connected through a pivot block 23, and the other end of the pivot block 23 is pivotally connected to a pivot seat 24, and the pivot seat 24 is connected to the second door body 22. This kind of setting can not only simplify the structure, but also ensure the smoothness of the opening and closing process of the first door body 21 and the second door body 22. At the same time, the pivot block 23 can play a certain supporting effect on the first door body 21 and the second door body 22, avoiding friction between the first door body 21 and the second door body 22 and the first support rod 12 and the second support rod 13 under the action of gravity and hindering the opening and closing of the doorway 11.

[0043] Specifically, as Figure 2 shown, the first driving component 31 includes a first driving member 311 and a first transition plate 312. One end of the first driving member 311 is connected to the support mechanism 10, and the output end is hinged to the first transition plate 312, and the first transition plate 312 is hinged to the first door body 21. In this structure, the first driving member 311 is arranged on the support mechanism 10, which ensures the stability of the process of opening and closing the first door body 21. When its output end extends, it can push the first transition plate 312 and generate relative rotation with the first transition plate 312. The first transition plate 312 can indirectly push the first door body 21 in a direction away from the doorway 11. At the same time, the first transition plate 312 and the first door body 21 are in a hinged state. Therefore, while ensuring that the first door body 21 can be smoothly opened, the rotation effects between the first driving member 311 and the first transition plate 312, and between the first transition plate 312 and the first door body 21 are ensured, avoiding rigid connection and ensuring the convenience and smoothness of opening and closing the first door body 21.

[0044] In addition, the structure of the second driving component 32 is the same as that of the first driving component 31, including a second driving member 321 and a second transition plate 322. The second driving member 321 is connected to the support mechanism 10, and its output end is hinged to the second transition plate 322, and the second transition plate 322 is hinged to the second door body 22. The second driving member 321 is arranged on the support mechanism 10, which ensures the stability of the process of opening and closing the second door body 22. When its output end extends, it can push the second transition plate 322 and generate relative rotation with the second transition plate 322. The second transition plate 322 can indirectly push the second door body 22 in a direction away from the door opening 11. At the same time, the second transition plate 322 and the second door body 22 are in a hinged state. Therefore, while ensuring that the second door body 22 can be smoothly opened, the rotation effects between the second driving member 321 and the second transition plate 322, and between the second transition plate 322 and the second door body 22 are ensured, rigid connection is avoided, and the convenience and smoothness of opening and closing the second door body 22 are guaranteed.

[0045] It should be noted that both the first driving member 311 and the second driving member 321 are telescopic cylinders. The structure of the cylinder is simple, the price is low, it is convenient for installation and use, and the operation difficulty can be reduced; and the first driving component 31 and the second driving component 32 adopt the same structure, which can effectively reduce the cost. In addition, the first driving member 311 is detachably connected to the base 15 through the first connecting seat 316, and the second driving member 321 is detachably connected to the base 15 through the second connecting seat 326. This not only facilitates installation, has a stable structure, but also is convenient for subsequent maintenance and replacement.

[0046] Specifically, as Figure 2 shown, the first driving component 31 further includes a first pin shaft 313, a first mounting seat 314 and a first driving bearing 315. The first mounting seat 314 is detachably mounted on the first transition plate 312, and its output end is connected to the first driving bearing 315. The first pin shaft 313 is used to mount the first driving bearing 315 on the first mounting seat 314. The first mounting seat 314 can not only simplify the connection structure, but also jointly ensure the stability of the first driving bearing 315 with the first pin shaft 313. The first driving bearing 315 can ensure the rotation effect between the output end of the first driving member 311 and the first transition plate 312, and the detachable connection between the first mounting seat 314 and the first transition plate 312 ensures the convenience of subsequent maintenance or replacement.

[0047] In addition, as Figure 2As shown in the figure, the second driving assembly 32 further includes a second pin shaft 323, a second mounting seat 324, and a second driving bearing 325. The second mounting seat 324 is detachably mounted on the second transition plate 322, and the output end is connected to the second driving bearing 325. The second pin shaft 323 is used to mount the second driving bearing 325 on the second mounting seat 324. The second mounting seat 324 can not only simplify the connection structure, but also jointly ensure the stability of the second driving bearing 325 with the second pin shaft 323. The second driving bearing 325 can ensure the rotation effect between the output end of the second driving member 321 and the second transition plate 322. Moreover, the detachable connection between the second mounting seat 324 and the second transition plate 322 ensures the convenience of subsequent maintenance or replacement.

[0048] It should be noted here that, as Figure 2 shown in the figure, a first connecting plate 318 is provided on the first transition plate 312. The first connecting plate 318 is mounted on the first door body 21. The first transition plate 312 is hinged to the first connecting plate 318 through a first rotating bearing 317, which not only ensures the smooth rotation of the first transition plate 312, but also ensures the stability of the connection between the first transition plate 312 and the first door body 21. Correspondingly, a second connecting plate 328 is provided on the second transition plate 322. The second connecting plate 328 is mounted on the second door body 22. The second transition plate 322 is hinged to the second connecting plate 328 through a second rotating bearing 327, which not only ensures the smooth rotation of the second transition plate 322, but also ensures the stability of the connection between the second transition plate 322 and the second door body 22.

[0049] To prevent the opening angles of the first door body 21 and the second door body 22 from being too large, as Figure 4 shown in the figure, the automatic door opening and closing device further includes a limiting assembly 40. The limiting assembly 40 includes a limiting plate 41 and a limiting block 42. The limiting plate 41 is provided on both sides of the support mechanism 10 in the width direction. The limiting block 42 is provided at the bottom end of the first transition plate 312. The limiting plate 41 can abut against the limiting block 42 to limit the rotation angle of the first door body 21. During the process of opening and closing the first door body 21, the first transition plate 312 can drive the limiting block 42 to move. After rotating a certain angle, the limiting plate 41 can block the movement of the limiting block 42, thereby preventing the opening angle of the first door body 21 from being too large.

[0050] It should be noted here that limiting plates 41 are provided on both sides of the support mechanism 10 in the length direction. That is, after the second driving member 321 drives the second transition plate 322 to rotate a preset angle, the second transition plate 322 can also drive the limiting block 42 to abut against the limiting plate 41 on the same side, so as to limit the first door body 21 and the second door body 22 at the same time, improving the user experience.

[0051] As Figure 2 and Figure 4As shown, the automatic door opening and closing mechanism further includes a guiding mechanism 50, which is used to open and close the first door body 21 and the second door body 22 along a preset direction. By providing the guiding mechanism 50, the opening and closing processes of the first door body 21 and the second door body 22 can be prevented from deviating from the preset direction, thereby avoiding interference between the first door body 21 and the second door body 22 and ensuring the usage efficiency.

[0052] Specifically, as Figure 2 and Figure 4 shown, the guiding mechanism 50 includes a first guiding component 51, a second guiding component 52 and a guide rail 53. Guide rails 53 are provided on both sides of the supporting mechanism 10 along the length direction, and the guide rails 53 extend along the width direction of the supporting mechanism 10; one end of the first guiding component 51 is slidably connected to the guide rail 53, and the other end is connected to the first door body 21, and one end of the second guiding component 52 is slidably connected to the guide rail 53, and the other end is connected to the second door body 22. In this structure, one ends of the first guiding component 51 and the second guiding component 52 are slidably connected to the guide rail 53, so the first guiding component 51 and the second guiding component 52 can slide along the extending direction of the guide rail 53, thereby indirectly driving the first door body 21 and the second door body 22 to open and close along the preset direction through the other ends, ensuring good usage effects.

[0053] In addition, as Figure 2 described, the first guiding component 51 includes a first guiding rod 511, a first guiding bearing 512 and a first sliding bearing 513 respectively connected to both ends of the first guiding rod 511. The first guiding bearing 512 is pivotally connected to the first guiding seat 514, the first guiding seat 514 is connected to the first door body 21, and the first sliding bearing 513 is slidably connected within the guide rail 53. In this structure, the first guiding seat 514 reduces the installation difficulty of the first guiding bearing 512, and at the same time provides a stable supporting condition for the connection between the first guiding rod 511 and the first guiding bearing 512, ensuring the stability when the first guiding rod 511 drives the first door body 21 to move.

[0054] In addition, as Figure 2 described, the second guiding component 52 includes a second guiding rod 521, a second guiding bearing 522 and a second sliding bearing 523 respectively connected to both ends of the second guiding rod 521. The second guiding bearing 522 is pivotally connected to the second guiding seat 524, the second guiding seat 524 is connected to the second door body 22, and the second sliding bearing 523 is slidably connected within the guide rail 53. In this structure, the second guiding seat 524 reduces the installation difficulty of the second guiding bearing 522, and at the same time provides a stable supporting condition for the connection between the second guiding rod 521 and the second guiding bearing 522, ensuring the stability when the second guiding rod 521 drives the second door body 22 to move.

[0055] As Figure 2As shown, a flexible limit pad 60 is provided on the side of the top end (cross bar 14) of the support mechanism 10 close to the door body assembly 20. By providing the flexible limit pad 60, it can be avoided that the first door body 21 and the second door body 22 directly contact the cross bar 14 when closing the doorway 11, thereby avoiding wear of the first door body 21, the second door body 22 and the cross bar 14 after long-term use. At the same time, it can also play a good buffering role during the closing process of the door, greatly improving the service life. It should be noted that the flexible limit pad 60 is made of polyurethane material.

[0056] As Figure 5 shown, a flexible limit pad 60 is provided on the side of the bottom end (base 15) of the support mechanism 10 close to the door body assembly 20. By providing the flexible limit pad 60, it can be avoided that the first door body 21 and the second door body 22 directly contact the base 15 when closing the doorway 11, and avoid wear of the first door body 21, the second door body 22 and the base 15 after long-term use. At the same time, it can also play a good buffering role during the closing process of the door, greatly improving the service life.

[0057] In addition, as Figure 1 and Figure 5 shown, the automatic door also includes a switch assembly 70. The switch assembly 70 includes a fixed block 71, a mechanical switch 72 and a switch striker plate 73. The mechanical switch 72 is installed on the fixed block 71. The fixed block 71 is arranged on the side of the first door body 21 close to the second door body 22. The switch striker plate 73 is arranged on the side of the second door body 22 close to the first door body 21. When the first door body 21 and the second door body 22 close the doorway 11, the mechanical switch 72 can abut against the switch striker plate 73 and can send a prompt that the doorway 11 has been closed. This setting can, after the first door body 21 and the second door body 22 are closed, make the mechanical switch 72 abut against and squeeze the switch striker plate 73, thereby triggering a prompt that the door body assembly 20 has closed the doorway 11, and then reminding the operator that the door closing has been completed and subsequent operations can be carried out, avoiding misjudgment; moreover, the mechanical switch 72 is arranged on the fixed block 71, ensuring good stability and also improving the installation convenience of the mechanical switch 72.

[0058] Combined with the attached drawings, describe the working process of the automatic door in this embodiment:

[0059] First, the output ends of the first driving member 311 and the second driving member 321 extend out, and the first door body 21 and the second door body 22 are pushed to rotate away from the doorway 11 through the first transition plate 312 and the second transition plate 322;

[0060] Secondly, one end of the first guide rod 511 and the second guide rod 521 slides along the extension direction of the guide rail 53, and the other end drives the first door body 21 and the second door body 22 to rotate in a preset direction until the limiting block 42 abuts against the limiting plate 41, and the first door body 21 and the second door body 22 reach the target opening degree;

[0061] Finally, after the operation is completed, the output ends of the first driving member 311 and the second driving member 321 retract, thereby driving the first door body 21 and the second door body 22 to rotate towards the direction close to the door opening 11 until the mechanical switch 72 abuts against the switch striker 73 and gives a prompt that the door closing has been completed.

[0062] In summary, the automatic door can forcibly close the door opening 11 by the first door body 21 and the second door body 22 during the laser cutting process, thereby reducing unnecessary shutdown of the equipment caused by manual accidental door opening, and at the same time improving the safety of the operator and the production efficiency of the equipment.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
