Description

Technical Field

[0001] The present invention relates to the technical field of electric doors, and in particular to a door row assembly and an airborne door. Background Art

[0002] Airborne doors are widely used in the entrances and exits of highway toll stations, parking lots, communities, and enterprises and institutions to facilitate and orderly manage the entry and exit of motor vehicles. They can also be designed to be higher and applied to the entrances and exits of villas, courtyards, etc. to achieve the purpose of anti-theft. The airborne door includes a chassis and a door row assembly. The door row assembly includes a face beam and a bottom beam arranged relatively to each other and a number of vertical rods arranged therebetween. The two ends of the vertical rods are rotatably connected to the face beam and the bottom beam, respectively. A driving mechanism is provided in the chassis to drive the door row assembly to rise and fall. When the door row assembly rises, the face beam and the bottom beam rotate relative to each other, so that a number of vertical rods are in an inclined state. When the door row assembly falls, the face beam and the bottom beam rotate relative to each other, so that a number of vertical rods are in a state perpendicular to the face beam and the bottom beam. In this way, the airborne door is opened by the rising of the door row assembly, at which time the door row assembly is folded and stored in the chassis, and the airborne door is closed by the falling of the door row assembly, at which time the door row assembly is horizontally spread on the ground.

[0003] In the traditional airborne door structure, a number of vertical rods are arranged in a straight line at intervals. If you want to ensure that there is no interference between two adjacent vertical rods when the door row assembly is raised, the distance between the two adjacent vertical rods needs to be designed to be larger, which causes the door row assembly to occupy a larger space after it is raised. Based on this defect, the existing airborne door staggers a number of vertical rods into two rows to reduce the distance between two adjacent vertical rods, so that the door row assembly occupies a smaller space after it is raised, and there is no interference between two adjacent vertical rods when the door row assembly is raised.

[0004] Although the two-row vertical rod structure of the airborne door reduces the space occupied by the door row assembly after it is raised compared to the linear vertical rod structure, it still has the following defects: in order to avoid interference between two adjacent vertical rods in the same row when the door row assembly is raised, a large distance between the two adjacent vertical rods is still required, so that the space occupied by the door row assembly after it is raised is still relatively large. At the same time, the large distance between the two adjacent vertical rods is easy for people's heads, bodies and other parts to drill into, which not only has a poor anti-theft effect, but also if the door row assembly is not withdrawn in time when it is raised, it is likely to be stuck and cause a safety accident. Summary of the invention

[0005] In order to overcome at least one of the defects described in the above-mentioned prior art, one of the objects of the present invention is to provide a door row assembly, which can significantly reduce the distance between two adjacent vertical rods to prevent people's heads, bodies and other parts from drilling into it, and can avoid safety accidents while improving the anti-theft effect. At the same time, it can ensure that the door row assembly occupies a smaller space after being raised, and avoid interference between two adjacent vertical rods in the same row when the door row assembly is raised.

[0006] The second object of the present invention is to provide an airborne door, which utilizes a chassis to drive the door row assembly to rise, and the door row assembly is folded and stored to have a smaller volume, so that the airborne door can occupy a smaller space when opened, and the airborne door has a better anti-theft effect when closed.

DETAILED DESCRIPTION

[0042] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0045] See also Figure 2-4The present invention provides a door row assembly, comprising a face beam 1, a bottom beam 2 and a vertical rod group 3, wherein the bottom beam 2 is arranged opposite to the face beam 1. The vertical rod group 3 is arranged between the face beam 1 and the bottom beam 2, and the vertical rod group 3 comprises a plurality of vertical rods 31 arranged at intervals along the length direction of the bottom beam 2, the plurality of vertical rods 31 are arranged in at least three rows along the width direction of the bottom beam 2, and the plurality of vertical rods 31 are staggeredly distributed along the length direction and the width direction of the bottom beam 2, and the two ends of the vertical rods 31 are rotatably connected to the face beam 1 and the bottom beam 2, respectively.

[0046] Generally, the face beam 1 and the bottom beam 2 are arranged parallel to each other. When the door row assembly is lowered to the ground, the face beam 1 and the bottom beam 2 are both arranged horizontally, and the two are used to carry and connect the vertical rod group 3. The plurality of vertical rods 31 of the vertical rod group 3 are all rotated to connect the face beam 1 and the bottom beam 2, so as to realize the free conversion between the inclined and vertical states of the face beam 1, the bottom beam 2 and the vertical rod 31 during the lifting and lowering process of the door row assembly. When the door row assembly is lowered to the ground, the plurality of vertical rods 31 in the vertical rod group 3 are generally in a vertical state and perpendicular to the face beam 1 and the bottom beam 2. The spacing between the plurality of vertical rods 31 is set so that when the vertical rods 31 become inclined after the door row assembly is raised, there will be no interference between the two adjacent vertical rods 31, so as to ensure the smooth lifting and lowering of the door row assembly.

[0047] by Figure 2 The direction shown is the standard, the x direction is the length direction, and the y direction is the width direction. If you want to avoid the interference problem when the door row assembly is raised, it is necessary to ensure that there is a sufficiently large spacing between the two adjacent vertical rods 31 in the same row in the length direction. However, based on safety requirements, the door row assembly should prevent people from mistakenly extending their heads or other parts of the body into the gap between the two adjacent vertical rods 31, so as to avoid safety accidents such as being hoisted when the door row assembly is raised due to the failure of people to exit in time. In addition, based on the anti-theft requirements of villas, courtyards, etc., the door row assembly should prevent people from passing through the gap between the two adjacent vertical rods 31. At the same time, after the door row assembly is raised, it should avoid excessive occupation of the space of the doorway, so as to avoid unsmooth passage of people or vehicles or even collisions. Based on these requirements, the spacing between any two adjacent vertical rods 31 in the vertical rod group 3 of the door row assembly should be controlled as small as possible, and the occupied space should be controlled as small as possible after the door row assembly is raised.

[0048] In order to solve the above-mentioned interference problems, small spacing, and small space requirements, combined with Fig.11 and Fig.12The vertical bar group 3 of the door row assembly of the present invention is provided with at least three rows along the width direction, and the vertical bars 31 of at least three rows of vertical bar groups 3 are staggered along the length direction and the width direction of the bottom beam, which can reduce the distance between any two adjacent vertical bars 31 in the entire vertical bar group 3, and at the same time ensure sufficient distance between two adjacent vertical bars 31 in the same row, so as to avoid the problem of interference between two adjacent vertical bars 31 in the same row when the door row assembly is raised, so that the door row assembly can be raised and lowered smoothly. At the same time, after the door row assembly is raised, there is no obvious gap between two adjacent vertical bars 31 in the same row, and the occupied space is small. In addition, the door row assembly has a large density of vertical bars 31, and the small distance between two adjacent vertical bars 31 can prevent the head, body and other parts of a person from drilling in, so as to achieve the purpose of anti-theft after the door row assembly is lowered, and at the same time, it is prevented from getting stuck on the body parts of a person when the door row assembly is raised, so as to ensure the safety of the use of the door row assembly and personal safety.

[0049] Specifically, at least three rows of vertical rods 31 are arranged at equal intervals along the width direction of the bottom beam 2, and the vertical rods 31 in each row are arranged at equal intervals along the length direction of the bottom beam 2. At least three rows of vertical rods 31 are arranged regularly, and are always arranged in the same order along the length direction, and two adjacent vertical rods 31 are arranged at equal intervals, so that at least three rows of vertical rods 31 are evenly arranged. In this way, this arrangement method can ensure that the distance between any two adjacent vertical rods 31 is small enough to ensure safety and occupy a small space after the door row assembly is raised, and the distance between two adjacent vertical rods 31 in the same row is sufficient to avoid interference problems. Combined with Figure 1 , Fig.11 and Fig.12 The vertical rod group 3 of the present invention is arranged in at least three rows along the width direction. When the door row assembly is lowered to the ground, there is a small spacing between two adjacent vertical rods 31, which can prevent people from drilling in to ensure safety. After the door row assembly is raised, there is almost no gap between two adjacent vertical rods 31 in the same row, and the bottom beam 2 of the door row assembly is almost flush with the side wall of the chassis 8. The space occupied by the door row assembly when folded and stowed is very small, ensuring smooth passage of people and vehicles and avoiding collisions.

[0050] See also Figure 3 and Figure 5 The face beam 1 and the bottom beam 2 are both provided with a plurality of mounting seats 4, and the two ends of the vertical rod 31 are rotatably connected to the corresponding mounting seats 4 through the connecting blocks 34. The mounting seats 4 can be fixed on the corresponding face beam 1 and the bottom beam 2 as an integral structure, or can be detachably installed on the face beam 1 and the bottom beam 2. The detachable mounting structure is preferred, and the installation position can be adjusted according to the needs, and the applicability is strong. The connecting block 34 is fixedly connected to the vertical rod 31, and the connecting block 34 is rotatably connected relative to the mounting seat 4, so that the vertical rod 31 can be rotatably connected to the mounting seat 4 by using the connecting block 34, thereby realizing that the vertical rod 31 can rotate relative to the face beam 1 and the bottom beam 2.

[0051] The connection block 34 includes a plug-in block 341 plugged with the vertical rod 31, and a docking block 342 detachably connected to and opposite to the plug-in block 341. The plug-in block 341 and the docking block 342 are respectively arranged on both sides of the mounting seat 4 and are rotatably connected to the mounting seat 4. Both ends of the vertical rod 31 are cavity structures, the plug-in block 341 is inserted at the end of the vertical rod 31, and the docking block 342 is arranged opposite to the plug-in block 341 and detachably connected. When the plug-in block 341 and the docking block 342 are rotatably connected to the opposite sides of the mounting seat 4, the plug-in block 341 and the docking block 342 are connected to form a fixed structure, so that the vertical rod 31 is rotatably connected to the mounting seat 4 by using the connection block 34.

[0052] The mounting seat 4 is provided with a mounting hole 41, and the plug-in block 341 and the docking block 342 are respectively provided with a connecting shaft 343 that is rotatably matched with the mounting hole 41. The two connecting shafts 343 are arranged opposite to each other, and the plug-in block 341 and the docking block 342 are respectively provided with a through hole 344 that is coaxially arranged with the corresponding connecting shaft 343. The two connecting shafts 343 that are arranged opposite to each other are connected by a fastener 32 that is axially inserted therein, and there are matching blocking members 33 in the two through holes 344. During installation, the plug-in block 341 is inserted at the end of the vertical rod 31, and the plug-in block 341 and the docking block 342 are respectively placed on opposite sides of the mounting seat 4, so that the two connecting shafts 343 are relatively rotatably inserted into the mounting hole 41, and are passed into the two connecting shafts 343 from the through hole 344 on one side along the axis through the fastener 32, so that the two connecting shafts 343 are connected by the fastener 32 to prevent the two connecting shafts 343 from coming out of the mounting hole 41. After the fasteners 32 lock the two connecting shafts 343, the two through holes 344 are blocked by the blocking member 33 to achieve an aesthetic effect. In this way, the present invention realizes a stable and rotatable installation of the vertical rod 31 and the mounting seat 4 by inserting the connecting shafts 343 of the plug block 341 and the docking block 342 into the mounting hole 41 and connecting the two connecting shafts 343 by the fasteners 32.

[0053] The fastener 32 may be a screw, a pin or other connector, and the plugging member 33 may be a rubber plug or other structure. Of course, in practical applications, a through hole structure may be provided at the end of the vertical rod 31, and an axis structure may be provided at the mounting seat 4, so as to realize the rotational connection between the axis and the through hole and the vertical rod 31 and the mounting seat 4.

[0054] For the detachable connection structure between the mounting base 4 and the face beam 1 and the bottom beam 2, see Figure 6-9The bottom of the face beam 1 and the top of the bottom beam 2 are respectively provided with a first receiving groove 11 and a second receiving groove 21 along the length direction thereof, and a plurality of mounting seats 4 can be slidably disposed in the corresponding first receiving groove 11 or second receiving groove 21, and abutted in sequence along the length direction of the face beam 1 or the bottom beam 2. The mounting seats 4 are installed at the bottom of the face beam 1 and the top of the bottom beam 2, so as to facilitate the use of the abutment arrangement of the plurality of mounting seats 4 to avoid sliding relative to the first receiving groove 11 or the second receiving groove 21, so as to ensure the accuracy of the installation position of the vertical rod 31.

[0055] The mounting seat 4 includes a base 42 slidably connected to the first receiving groove 11 or the second receiving groove 21, and a connecting ear 43 connected to the base 42, and the connecting ear 43 is rotatably connected to the corresponding vertical rod 31; the structure of a row of connecting ears 43 corresponding to a row of vertical rods 31 is the same, and a row of connecting ears 43 is arranged at intervals from another row of connecting ears 43 adjacent thereto. The base 42 is slidably arranged in the first receiving groove 11 or the second receiving groove 21, and the connecting ear 43 is arranged on the base 42. The connecting ear 43 is provided with a mounting hole 41, so that the two connecting shafts 343 of the plug-in block 341 and the docking block 342 are respectively rotated and inserted into the mounting hole 41 from the opposite sides of the connecting ear 43 to realize the rotation connection between the vertical rod 31 and the mounting seat 4. The structure of a row of connecting ears 43 is the same, which is convenient for installation, and there is no need to deliberately select the installation position. The adjacent rows of connecting ears 43 are arranged at intervals to provide sufficient space for the rotation and folding of the vertical rod 31 to avoid interference.

[0056] At least one side wall of the base 42 in the width direction is provided with a block 421 protruding outward, at least one side wall of the first receiving groove 11 is bent inward to form a first receiving groove 111 that is slidably matched with the corresponding block 421, and at least one side wall of the second receiving groove 21 is bent inward to form a second receiving groove 211 that is slidably matched with the corresponding block 421. The first receiving groove 11 and the second receiving groove 21 can have one side wall bent inward to form a first receiving groove 111 and a second receiving groove 211, respectively. At this time, a block 421 is protruding on the same side of the base 42, and the block 421 can be slidably arranged in the corresponding first receiving groove 111 or the second receiving groove 211, so that the base 42 can slide to the installation position, and the base 42 can be prevented from falling out of the corresponding first receiving groove 11 or the second receiving groove 21, thereby ensuring the stable installation of the mounting seat 4 and the corresponding surface beam 1 or bottom beam 2. Of course, the first accommodating groove 11 and the second accommodating groove 21 can also have both side walls bent inward to form two first card slots 111 and two second card slots 211 respectively. At this time, the base 42 can have a protruding block 421 on any side wall, or both side walls can form a card block 421.

[0057] On the basis of the above structure, a plurality of vertical rods 31 can be arranged in three rows, four rows, five rows, etc. along the width direction. The more rows there are, the smaller the spacing between two adjacent vertical rods 31 can be set, that is, the greater the density of the vertical rods 31, which not only further improves the safety of use, but also ensures that the spacing between two adjacent vertical rods 31 in the same row is sufficient to avoid interference, and at the same time, it can occupy a smaller space after the door row assembly is raised. In general, it is sufficient to arrange three rows of a plurality of vertical rods 31 along the width direction to meet all the above requirements. Although more rows have the above advantages, it will increase the width of the face beam 1 and the bottom beam 2 and the number of vertical rods 31, thereby greatly increasing the weight of the entire door row assembly, and the power consumption of the door row assembly when it is raised and lowered will also increase accordingly. Therefore, preferably, a plurality of vertical rods 31 are arranged in three rows along the width direction. The plurality of vertical rods 31 of the three-row structure are described in detail below in conjunction with the accompanying drawings. In actual applications, a plurality of vertical rods 31 are arranged in four rows, five rows, etc., which can be adjusted according to the adaptability of the following structure, and will not be described in detail here.

[0058] See also Figure 2-5 , a plurality of vertical rods 31 are arranged in three rows along the width direction of the bottom beam 2, namely the first vertical rod group 301, the second vertical rod group 302 and the third vertical rod group 303, the two ends of the vertical rods 31 of the second vertical rod group 302 are rotatably connected to the bottom of the surface beam 1 and the top of the bottom beam 2 respectively, the top ends of the vertical rods 31 of the first vertical rod group 301 and the third vertical rod group 303 are rotatably connected to the two sides of the width direction of the surface beam 1 respectively, and the bottom ends of the vertical rods 31 of the first vertical rod group 301 and the third vertical rod group 303 are rotatably connected to the two sides of the width direction of the bottom beam 2 respectively; the connecting ear 43 corresponding to the first vertical rod group 301 is arranged on one side of the corresponding base 42, the connecting ear 43 corresponding to the second vertical rod group 302 is arranged on the corresponding base 42, and the connecting ear 43 corresponding to the third vertical rod group 303 is arranged on the other side of the corresponding base 42.

[0059] Generally, both ends of the vertical rods 31 of the first vertical rod group 301, the second vertical rod group 302 and the third vertical rod group 303 are rotatably connected to the bottom of the surface beam 1 and the top of the bottom beam 2, respectively. However, this will increase the width of the surface beam 1 and the bottom beam 2, thereby increasing the weight of the surface beam 1 and the bottom beam 2, and the cost and driving power consumption will increase. Figure 3, the two ends of the vertical rod 31 of the second vertical rod group 302 of the present invention are rotatably connected to the bottom of the face beam 1 and the top of the bottom beam 2, the tops of the vertical rods 31 of the first vertical rod group 301 and the third vertical rod group 303 are rotatably connected to the two sides of the face beam 1 in the width direction, and the bottom ends of the vertical rods 31 of the first vertical rod group 301 and the third vertical rod group 303 are rotatably connected to the two sides of the bottom beam 2 in the width direction. In this way, the two ends of the second vertical rod group 302 located in the middle are respectively installed at the bottom of the face beam 1 and the top of the bottom beam 2, and the first vertical rod group 301 and the third vertical rod group 303 located on both sides are installed at the side of the face beam 1 and the bottom beam 2, so that the space at the side of the face beam 1 and the bottom beam 2 can be fully utilized to realize the installation of the first vertical rod group 301 and the third vertical rod group 303, so as to reduce the width of the face beam 1 and the bottom beam 2, thereby reducing the weight of the door row assembly and the driving power consumption.

[0060] Of course, when the vertical rods 31 are arranged in four rows along the width direction, the two middle groups can be installed at the bottom of the face beam 1 and the top of the bottom beam 2, and the same can be done when there are five rows or more. However, it will increase the width of the face beam 1 and the bottom beam 2. Therefore, it is preferred that the vertical rods 31 are arranged in three rows along the width direction, which just ensures that one row is installed on both sides and the middle of the face beam 1 and the bottom beam 2. This can not only achieve the effects of avoiding interference, occupying a small space and having good safety of the present invention, but also ensure that the door row assembly has a smaller weight to reduce costs and driving power consumption.

[0062] A fixing strip 5 is provided between two adjacent connecting ears 43 provided on the side of the base 42, and the fixing strip 5 is adapted and slidably provided in the corresponding first fixing groove 12 or the second fixing groove 22. The fixing strip 5 is provided between the fixing portions 431 of the two adjacent connecting ears 43 on the same side, so that the fixing portions 431 and the fixing strip 5 are abutted in the corresponding first fixing groove 12 or the second fixing groove 22 along the length direction, and the stability of the fixing portion 431 after sliding to the installation position can be ensured to avoid shaking or displacement, so that the base 42 and the connecting ears 43 on the side thereof can be stably installed.

[0063] At least one side wall of the first fixing groove 12 and the second fixing groove 22 is bent inward to form a first groove 121 and a second groove 221, respectively. At least one side wall of the fixing portion 431 and the fixing strip 5 is protruded toward the corresponding first groove 121 or second groove 221 to form a first protrusion 432 and a second protrusion 51, respectively. The first protrusion 432 and the second protrusion 51 are both adapted and slidably arranged in the corresponding first groove 121 or second groove 221. The first fixing groove 12 and the second fixing groove 22 can both have one side wall bent inward to form a first groove 121 and a second groove 221 respectively. At this time, the fixing portion 431 and the fixing strip 5 are respectively provided with a first protrusion 432 and a second protrusion 51 on the same side. The first protrusion 432 and the second protrusion 51 can be slidably arranged in the corresponding first groove 121 or the second groove 221, so that the connecting ear 43 and the fixing strip 5 arranged on the side of the base 42 can be slid to the installation position, and the fixing portion 431 and the fixing strip 5 can be prevented from falling out of the corresponding first fixing groove 12 or the second fixing groove 22, thereby ensuring that the connecting ear 43 and the fixing strip 5 arranged on the side of the base 42 are firmly installed with the corresponding surface beam 1 or the bottom beam 2. Of course, the first fixing groove 12 and the second fixing groove 22 can also have both side walls bent inward to form two first grooves 121 and two second grooves 221 respectively. At this time, the fixing portion 431 and the fixing strip 5 can be protruded on any side wall to form a first protrusion 432 and a second protrusion 51 respectively, or both side walls can form the first protrusion 432 and the second protrusion 51.

[0064] In addition, see Figure 1 and Figure 2 The door row assembly of the present invention is also provided with a protective structure and a buffer structure. The protective structure is arranged at the bottom of the door row assembly to avoid hitting pedestrians, vehicles, etc. when the door row assembly falls. The buffer structure is arranged on the side of the door row assembly to play a buffering and shock-absorbing role when the door row assembly falls to the ground, so as to reduce damage to the bottom beam 2.

[0065] Specifically, see Figure 6 and Figure 7 The protective structure includes a buffer tube 6, which is detachably arranged at the bottom of the bottom beam 2. The two outer walls of the buffer tube 6 in the width direction extend upward to form a plug-in portion 61, and a matching slot 23 is provided at the bottom of the bottom beam 2 corresponding to the plug-in portion 61, so that the plug-in connection between the plug-in portion 61 and the slot 23 is used to realize a stable and detachable connection between the buffer tube 6 and the bottom beam 2. The buffer tube 6 can be a rubber hose. In this way, when the door row assembly is lowered, once pedestrians, vehicles, etc. pass by, the buffer tube 6 first contacts the pedestrians, vehicles, etc., so as to utilize the elastic buffering effect of the buffer tube 6 to prevent the door row assembly from hitting pedestrians, vehicles, etc., so as to achieve the purpose of protecting pedestrians, vehicles, etc.

[0066] See also Figure 2 and Fig.10 The buffer structure includes a buffer rod assembly 7, which includes two fixed rods 71 ​​arranged at one end of the door row assembly away from the chassis 8. The two fixed rods 71 ​​are respectively arranged on both sides of the width direction of the door row assembly. The top and bottom ends of the two fixed rods 71 ​​are connected by a fixed shaft 72. The surface beam 1 and the bottom beam 2 are respectively provided with a first shaft sleeve 13 and a second shaft sleeve 24 adapted to the fixed shaft 72 along the width direction. The fixed shaft 72 at the top can rotatably pass through the first shaft sleeve 13 to fix the top ends of the two fixed rods 71, and the fixed shaft 72 at the bottom can rotatably pass through the second shaft sleeve 24 to fix the bottom ends of the two fixed rods 71, thereby realizing that the two fixed rods 71 ​​can be rotatably installed on the side of the door row assembly away from the chassis 8.

[0067] The bottom end of the fixing rod 71 is higher than the bottom end of the bottom beam 2, and a support rod 73 is provided on the lower side of the fixing rod 71 and is parallel to the fixing rod 71. A buffer pad 74 is provided at the bottom of the support rod 73, and the bottom end of the buffer pad 74 is lower than the bottom end of the bottom beam 2. The fixing rod 71 and the support rod 73 are connected by a fixing sleeve 75 and are locked by screws. In this way, when the door row assembly falls to the ground, the buffer pad 74 first contacts the ground to play a role of buffering and shock absorption, thereby avoiding damage to the bottom beam 2. At the same time, the buffer rod assembly 7 also has a supporting function, so that the door row assembly is stably supported on the ground.

[0068] In addition, the door row assembly may further include at least one reinforcing rod, which is horizontally or inclinedly arranged along the length direction. The reinforcing rod extends along the length direction and is fixedly connected to a plurality of vertical rods 31 of the copper busbar to improve the strength of the vertical rod group 3.

[0069] See also Figure 1 , Fig.11 and Fig.12 , including: a chassis 8 and the above-mentioned door row assembly, a driving mechanism connected to the door row assembly is arranged in the chassis 8, and the driving mechanism can drive the door row assembly to rotate, rise or fall in a vertical plane.

[0070] The airborne door drives the door row assembly to rise or fall through the driving mechanism in the chassis. When the door row assembly rises, it is almost folded and stored in a position flush with the side wall of the chassis 8, avoiding occupying the doorway space, so that the doorway is spacious and unobstructed when the airborne door is opened and occupies a small space, and it can avoid the door row assembly exceeding the side wall of the chassis 8, causing vehicles or pedestrians to accidentally collide and cause safety accidents. When the airborne door is closed, the door row assembly blocks the doorway with a larger density of vertical rods 31, which can prevent people from passing through, so as to achieve the purpose of anti-theft, and ensure the safety of the use of the airborne door and personal safety.
