[0025] Please refer to Figure 1 and Figure 2 One embodiment of this utility model discloses a folding door 100, including a first guide member 10, a steering member 20, and a door assembly 30. The first guide member 10 includes a first guide segment 12 and a second guide segment 14 connected to each other. The steering member 20 is located at the connection between the first guide segment 12 and the second guide segment 14 and is located on one side of the first guide member 10. The door assembly 30 includes a first door unit 32, a second door unit 34, and a steering engagement member 36. One end of the first door unit 32 is rotatably connected to one end of the second door unit 34. Both the first door unit 32 and the second door unit 34 are slidably connected to the first guide member 10. The steering engagement member 36 is connected to either the first door unit 32 or the second door unit 34.

[0026] During the opening of the folding door 100, when the steering engagement 36 passes the steering engagement 20, the steering engagement 36 and the steering engagement 20 cooperate, so that the first door unit 32 and the second door unit 34 begin to fold, and the other end of the first door unit 32 and the other end of the second door unit 34 can slide into the second guide section 14.

[0027] With the above structure, during the opening of the folding door 100, when the steering engagement 36 passes the steering engagement 20, the steering engagement 20 and the steering engagement 36 cooperate, which can trigger the first door unit 32 and the second door unit 34 of the door assembly 30 to start folding. When the first door unit 32 and the second door unit 34 start folding, no greater resistance will be generated, that is, no greater pushing force is required to make the first door unit 32 and the second door unit 34 start folding. After the first door unit 32 and the second door unit 34 start folding, under the guidance of the second guide section 14, the first door unit 32 and the second door unit 34 can run smoothly to ensure the smoothness of the folding process of the first door unit 32 and the second door unit 34.

[0035] The steering component 20 may include a structure for changing the direction of movement of the steering mating component 36. For example, the steering component 20 may have an arc-shaped guide groove. The steering mating component 36 may include a rotating wheel. When the steering mating component 36 is engaged with the steering component 20, the rotating wheel is located in the guide groove and abuts against the groove wall of the guide groove to trigger the first door unit 32 or the second door unit 34 to turn, so that the first door unit 32 and the second door unit 34 begin to fold or unfold.

[0036] It is understood that those skilled in the art can configure the steering component 20 into any structure with the function of changing the direction of movement based on the content disclosed in the embodiments of this utility model.

[0037] In this embodiment, there are four door groups 30. In the same door group 30, one end of the first door unit 32 and one end of the second door unit 34 can be hinged to each other for rotational connection. In two adjacent door groups 30, the other end of the second door unit 34 of one door group 30 can also be hinged to the other end of the first door unit 32 of the other door group 30 for rotational connection.

[0038] It is understood that those skilled in the art can set the number of door groups 30 according to the content disclosed in the embodiments of this utility model and according to actual needs.

[0039] In this embodiment, both the first door unit 32 and the second door unit 34 are rectangular door frame structures; in other embodiments, the first door unit 32 and the second door unit 34 may also be other structures, such as door panel structures; the first door unit 32 and the second door unit 34 may also be other shapes, such as arches.

[0040] In this embodiment, the folding door 100 may further include a second guide 40, a sliding engagement assembly 50, a drive assembly 60, a fixing assembly 70, and a connecting mechanism 80. The sliding engagement assembly 50 is mounted on the first guide 10, and the door assembly 30 is rotatably connected to the sliding engagement assembly 50, and the door assembly 30 is slidably connected to the first guide 10 via the sliding engagement assembly 50. The drive assembly 60 is connected to the door assembly 30 and is used to drive the first door unit 32 and the second door unit 34 to fold or unfold. The connecting mechanism 80 connects the fixing assembly 70 and the door assembly 30.

[0041] Please see Figure 3 In some embodiments, the folding door 100 further includes a connecting guide section 42 connected to the steering member 20; during the opening of the folding door 100, the steering mating member 36 can enter the connecting guide section 42 via the steering member 20; in the opening direction of the folding door 100, the distance between the connecting guide section 42 and the second guide section 14 gradually increases.

[0042] With the above structure, after the door assembly 30 begins to fold, the connecting guide section 42 guides the steering engagement 36. As the steering engagement 36 moves along the connecting guide section 42, the angle between the first door unit 32 and the second door unit 34 of the door assembly 30 decreases, that is, the door assembly 30 can gradually fold; in order to avoid the door assembly 30 getting stuck during the folding process.

[0043] In some embodiments, the folding door 100 further includes a third guide section 44 and a fourth guide section 46. The third guide section 44 is connected to the side of the steering member 20 facing away from the connecting guide section 42, and the fourth guide section 46 is connected to the side of the connecting guide section 42 facing away from the steering member 20. In the direction in which the folding door 100 is opened, the distance between the fourth guide section 46 and the second guide section 14 is consistent.

[0044] With the above structure, after the door assembly 30 is folded, the first door unit 32 and the second door unit 34 in the door assembly 30 fold to each other, and the door assembly 30 is located between the fourth guide section 46 and the second guide section 14, so that the fourth guide section 46 and the second guide section 14 can be used to accommodate the folded door assembly 30.

[0045] The third guide section 44, the steering component 20, the connecting guide section 42, and the fourth guide section 46 can all guide the steering mating component 36 so that during the opening of the folding door 100, the steering mating component 36 can move along the third guide section 44 before passing the steering component 20. As a result, the first door unit 32 and the second door unit 34 in the door assembly 30 can remain relatively stationary, avoiding the simultaneous folding of the entire door assembly 30, thereby reducing the maximum thrust required by the drive assembly 60.

[0046] In this embodiment, the connecting guide segment 42 can be bent toward the second guide segment 14, that is, the connecting guide segment 42 is arc-shaped, and the center of the connecting guide segment 42 and the second guide segment 14 are located on the same side of the connecting guide segment 42.

[0047] The first guide member 10, the steering member 20, and the second guide member 40 can all be fixed to the ground or the base plate, so that the first guide member 10, the steering member 20, and the second guide member 40 are all located below the door assembly 30.

[0048] In other embodiments, the first guide 10, the steering member 20, and the second guide 40 may further include a hanging track structure suspended or installed on the ceiling of the building, such that the first guide 10, the steering member 20, and the second guide 40 are located above the door assembly 30; or, the first guide 10, the steering member 20, and the second guide 40 may be arranged vertically to be installed on a vertically arranged wall or other fixed structure.

[0049] In some embodiments, the first guide 10, the steering member 20, the connecting guide section 42, the third guide section 44, the fourth guide section 46, and the steering mating member 36 can be combined to form a steering mechanism that causes the door assembly 30 to fold.

[0050] In this embodiment, the steering component 20, the connecting guide section 42, the third guide section 44, and the fourth guide section 46 can be integrally formed.

[0051] In other embodiments, the steering component 20 and the connecting guide section 42, the third guide section 44 and the steering component 20, and the connecting guide section 42 and the fourth guide section 46 can also be connected to each other by splicing.

[0052] In some embodiments, the first guide segment 12, the second guide segment 14, the third guide segment 44 and the fourth guide segment 46 are all straight lines, the first guide segment 12 and the second guide segment 14 are located on the same straight line, and the first guide segment 12 is parallel to the third guide segment 44 and the fourth guide segment 46.

[0053] Based on the above structure, the first guide section 12 and the fourth guide section 46 are parallel to each other, and it can be inferred that the second guide section 14 and the fourth guide section 46 are parallel to each other. When the dimensions of each door group 30 of the folding door 100 are the same, all door groups 30 can be accommodated together between the second guide section 14 and the fourth guide section 46 after folding.

[0054] In other embodiments, the first guide segment 12, the second guide segment 14, the third guide segment 44 and the fourth guide segment 46 may also be arranged in a curved shape with a certain arc; in addition, the fourth guide segment 46 and the third guide segment 44, the third guide segment 44 and the first guide segment 12, and the fourth guide segment 46 and the first guide segment 12 may be at other angles.

[0055] In some embodiments, the third guide segment 44 has a first guide groove 4402, the steering member 20 has an arc-shaped guide groove 202, and the connecting guide segment 42 has an arc-shaped second guide groove 4202, which bends toward the second guide segment 14; the fourth guide segment 46 has a third guide groove 4602, and the first guide groove 4402, the arc-shaped guide groove 202, the second guide groove 4202, and the third guide groove 4602 are sequentially connected; the steering mating member 36 can move along the first guide groove 4402, the arc-shaped guide groove 202, the second guide groove 4402, and the third guide groove 4602.

[0056] With the above structure, the steering component 20 has an arc-shaped guide groove 202, and the connecting guide section 42 has an arc-shaped second guide groove 4202. The second guide groove 4202 is bent toward the second guide section 14. When the first door unit 32 and the second door unit 34 begin to fold, the steering mating component 36 can smoothly slide through the arc-shaped guide groove 202 and the arc-shaped second guide groove 4202 in sequence to ensure the smoothness of the folding process of the first door unit 32 and the second door unit 34.

[0057] The first guide groove 4402, the arc-shaped guide groove 202, the second guide groove 4202 and the third guide groove 4602 can all include blind grooves with rectangular or U-shaped cross sections, and the openings of the first guide groove 4402, the arc-shaped guide groove 202, the second guide groove 4202 and the third guide groove 4602 all face upward.

[0058] In some embodiments, the bending direction of the arc-shaped guide groove 202 may be opposite to the bending direction of the arc-shaped second guide groove 4202, so that the arc-shaped guide groove 202 and the second guide groove 4202 form an "S"-shaped structure when connected. This allows the steering mating member 36 to slide more smoothly from the arc-shaped guide groove 202 to the arc-shaped second guide groove 4202, thereby ensuring that the first door unit 32 and the second door unit 34 fold smoothly.

[0059] In other embodiments, the bending direction of the arc-shaped guide groove 202 may also be the same as the bending direction of the second guide groove 4202.

The body 362 is connected to the first door unit 32 or the second door unit 34, and the rotation guide 364 is rotatably connected to the body 362. The rotation guide 364 can move within the first guide groove 4402, the arc-shaped guide groove 202, the second guide groove 4202, and the third guide groove 4602.

[0066] With the above structure, the rotating guide 364 can move within the first guide groove 4402, the arc-shaped guide groove 202, the second guide groove 4202, and the third guide groove 4602. When the rotating guide 364 moves within the first guide groove 4402, the door assembly 30 remains in the unfolded state, and the included angle between the first door unit 32 and the second door unit 34 is 180° or other preset angle. When the rotating guide 364 moves within the arc-shaped guide groove 202, the door assembly 30 begins to fold, and the included angle between the first door unit 32 and the second door unit 34 begins to decrease. When the rotating guide 364 moves within the second guide groove 4202, the door assembly 30 gradually completes its folding, and the included angle between the first door unit 32 and the second door unit 34 gradually decreases to 0°. When the rotating guide 364 moves within the third guide groove 4602, the folded door assembly 30 is housed between the fourth guide section 46 and the second guide section 14.

[0068] With the above structure, the steering wheel 366 is located on the side of the body 362 facing away from the first guide member 10, and the rotating guide member 364 is located on the side of the body 362 facing the first guide member 10; so that the steering wheel 366 and the rotating guide member 364 can simultaneously support the opposite sides of the body 362, thereby reducing the shaking of the body 362 during movement and making it more stable.

[0069] Specifically, the main body 362 can be connected to the lower side of the second door unit 34, and the main body 362 can be located at the end of the second door unit 34 facing the first door unit 32; the main body 362 can include a trapezoidal plate-like structure, the rotation axis of the rotating guide 364 can be set perpendicular to the horizontal plane, the rotating guide 364 can include a cylindrical structure, and part of the rotating guide 364 extends into the first guide groove 4402, the arc-shaped guide groove 202, the second guide groove 4202, or the third guide groove 4602. The steering wheel 366 can include a universal wheel structure, and the steering wheel 366 can rotate relative to the ground, and at the same time, the steering wheel 366 can also rotate relative to the lower side of the main body 362.

[0070] Please see Figure 11 In some embodiments, the rotating guide 364 includes a rotating shaft 3642 and a collar 3644. The body 362 includes a shaft assembly 3622, which is sleeved on the upper end of the rotating shaft 3642. The rotating shaft 3642 is rotatably connected to the shaft assembly 3622, and the collar 3644 is fixedly sleeved on the lower end of the rotating shaft 3642.

[0071] The rotating shaft 3642 may include a cylindrical structure, and the axis of rotation of the rotating shaft 3642 is perpendicular to the horizontal plane; the shaft assembly 3622 may include a cylindrical structure, and the rotating shaft 3642 and the shaft assembly 3622 may be rotatably connected by two bearings, one bearing being located at the upper end of the shaft assembly 3622 and the other bearing being located at the lower end of the shaft assembly 3622; the collar 3644 may also include a cylindrical structure.

[0072] The collar 3644 can extend into the first guide groove 4402, the arc-shaped guide groove 202, the second guide groove 4202 or the third guide groove 4602; the collar 3644 can be made of a flexible material, such as rubber or silicone; the collar 3644 can also be made of a rigid material, such as plastic or metal.

[0073] In other embodiments, the rotation guide 364 may also include other structures, such as a block structure or a cylindrical structure for contacting the steering member 20 and causing deflection.

[0074] In other embodiments, the steering engagement 36 may include a target component fixed to the first door unit 32 or the second door unit 34 for contact with the steering member 20. The steering member 20 may move toward or away from the junction of the first guide segment 12 and the second guide segment 14. When the steering member 20 moves toward the junction of the first guide segment 12 and the second guide segment 14, it can push the steering engagement 36 to drive the first door unit 32 or the second door unit 34 of the folding door 100, so that the door assembly 30 begins to fold. When the steering member 20 has an arc-shaped guide groove 202, the steering engagement 36 may also include a structure fixed to the first door unit 32 or the second door unit 34, such as a columnar structure, so that the steering engagement 36 can extend into the arc-shaped guide groove 202.

[0075] It is understood that those skilled in the art can configure the steering fitting 36 into any structure that can have its direction of movement changed by the steering fitting 20, based on the content disclosed in the embodiments of this utility model.

[0076] In other embodiments, the steering member 20 may also include other structures, such as a pusher that can move toward or away from the door assembly 30. The steering member 20 is located on one side of the first guide section 12. The pusher of the steering member 20 can reciprocate. The steering engagement member 36 may include a target connected to the first door unit 32 or the second door unit 34 for the steering member 20 to contact. This is so that when each door assembly 30 passes the steering member 20, the steering member 20 can push the steering engagement member 36 to drive the first door unit 32 or the second door unit 34 of the folding door 100, so that the door assembly 30 begins to fold.

[0077] Please refer to the following: Figure 1 , Figure 12 and Figure 13 When there is one door group 30, the other end of the second door unit 34 facing away from the first door unit 32 is rotatably connected to a sliding fit assembly 50, and the other end of the first door unit 32 facing away from the second door unit 34 is rotatably connected to a drive assembly 60.

[0078] In some embodiments, when there are two or more door groups 30, in two adjacent door groups 30, the other end of the second door unit 34 of one door group 30 is rotatably connected to the other end of the first door unit 32 of the other door group 30.

[0079] The sliding fit assembly 50 is slidably connected to the first guide member 10, and the other end of the second door unit 34 of a door group 50 and the other end of the first door unit 32 of an adjacent door group 30 are respectively rotatably connected to a sliding fit assembly 50.

[0080] With the above structure, a sliding engagement component 50 at the connection of two adjacent door groups 30 can support the two adjacent door groups 30 at the same time; so that fewer sliding engagement components 50 can support the entire door group 30, thereby reducing the resistance when the folding door 100 unfolds or retracts.

[0081] Each sliding engagement component 50 can be disposed at the connection point of two adjacent door groups 30; the second door unit 34 of the door group 30 at the rear end of the folding door 100 is rotatably connected to a sliding engagement component 50; the first door unit 32 of the door group 30 at the front end of the folding door 100 is rotatably connected to the drive component 60. When the folding door 100 is open, the sliding engagement component 50 at the connection point of two adjacent door groups 30 is located below the two adjacent door groups 30.

[0082] Furthermore, the sliding engagement assembly 50 may include a main body 52, a guide engagement member 54, and a support member 56. The guide engagement member 54 is mounted on the main body 52 and slidably connected to the first guide member 10. The support member 56 is mounted on the main body 52 and is used to support the main body 52. ​​The guide engagement member 54 includes a first guide wheel 542 and a second guide wheel 544, both of which are rotatably connected to the main body 52.

[0083] The first guide member 10 includes a guide protrusion, and a first side guide groove 102 and a second side guide groove 104 can be respectively opened on the opposite sides of the guide protrusion.

[0084] The first guide wheel 542 extends into the first side guide groove 102, and the second guide wheel 544 extends into the second side guide groove 104.

[0085] Both the first side guide groove 102 and the second side guide groove 104 can be blind grooves with a rectangular cross-section. The first side guide groove 102 and the second side guide groove 104 can guide the sliding fit assembly 50 through the first guide wheel 542 and the second guide wheel 544, respectively.

[0086] The main body 52 may include a block-like structure similar to a cuboid, and the long side of the main body 52 may extend perpendicularly to the extension direction of the first guide member 10. There may be two first guide wheels 542 and two second guide wheels 544. In the extension direction of the first guide member 10, one first guide wheel 542 and one second guide wheel 544 are rotatably connected to one side of the main body 52 by a hinge or bearing connection, and the other first guide wheel 542 and the other second guide wheel 544 are rotatably connected to the opposite side of the main body 52 by a hinge or bearing connection. This allows the two first guide wheels 542 to be arranged along the first guide member 10 in the same sliding engagement assembly 50, and the two second guide wheels 544 to also be arranged along the first guide member 10, thereby enabling the guide engagement member 54 to slide more stably relative to the first guide member 10.

[0087] In other embodiments, the first guide member 10 may also include other structures, such as a structure with a guide groove or a structure similar to a rail. Correspondingly, the guide mating member 54 may also include other structures, such as a block-shaped member inserted into the guide groove or a roller for mating with a rail. The main body 52 may include other structures, such as a cylinder. The number of the first guide wheel 542 and the second guide wheel 544 may be other, such as one or three.

[0088] With the above structure, the main body 52 can move stably relative to the first guide member 10. When the first guide member 10 is in a straight line, the main body 52 can drive one end of the first door unit 32 and one end of the second door unit 34 to make a stable straight line movement, so as to avoid the first end of the first door unit 32 and one end of the second door unit 34 from deviating.

[0089] Please see Figure 14 and Figure 15 In some embodiments, the drive assembly 60 may include a drive structure such as a motor; during the opening of the folding door 100, the drive assembly 60 is used to drive the first door unit 32 of the door group 30 located at the first end of the folding door 100 to move, so as to drive all the door groups 30 to move simultaneously along the direction from the first guide section 12 to the second guide section 14; during the closing of the folding door 100, the drive assembly 60 is used to drive the first door unit 32 of the door group 30 located at the first end of the folding door 100 to move, so as to drive all the door groups 30 to move simultaneously along the direction from the second guide section 14 to the first guide section 12.

[0090] In this embodiment, the drive assembly 60 may include a mounting post 62, a motor housing 64, a support platform 66, a motor, a limiting wheel 68, and a support wheel 69. The mounting post 62 is rotatably connected to the other end of the first door unit 32 of the door assembly 30 at the head end of the folding door 100, and the other end of the mounting post 62 can be connected to the support platform 66. The mounting post 62 may include a cuboid columnar structure with the same height as the door assembly 30. The motor housing 64 may include a cuboid-like shell structure, and the motor housing 64 can be connected by screws or other means. The connector is fixed to the support platform 66; the support platform 66 can be a structure similar to a rectangular platform; the support wheel 69 is located below the support platform 66 and is used to support the drive assembly 60 on the ground or floor; the motor is housed in the motor housing 64 and is used to drive the support wheel 69 to rotate, thereby driving the door assembly 30 to move; the limiting wheel 68 protrudes from the lower side of the support platform 66 and cooperates with the first guide member 10 so that the drive assembly 60 can move along the first guide member 10, and the limiting wheel 68 can be partially housed in the first side guide groove 102 and the second side guide groove 104.

[0091] With the above structure, the motor drives the support wheel 69 to move, so that the mounting column 62 can push the door assembly 30 to move, thereby realizing the opening or closing of the folding door 100.

[0092] In other embodiments, the drive assembly 60 may also include other structures, such as a motor-driven linear module that may be buried underground and includes a push block that may be fixed to the first door unit 32 of the door assembly 30 at the head end of the folding door 100.

[0093] In some other embodiments, the first guide 10 may be partially located within the support platform 66, or the first guide 10 may pass through the support platform 66, and the limiting wheel 68 may be entirely located within the support platform 66.

[0094] In this embodiment, the height of the mounting post 62 can be the same as the height of the door assembly 30, and the motor housing 64 can be installed on the lower side of the mounting post 62.

[0095] In other embodiments, the height of the mounting post 62 may be higher or lower than the height of the door assembly 30; the motor housing 64 may also be mounted at other locations on the mounting post 62, such as the middle or the upper side.

[0096] It is understood that those skilled in the art, in conjunction with the information disclosed in the embodiments of this utility model, can configure the drive component 60 into any structure that meets the drive function requirements.

[0097] Please see Figure 16The fixing component 70 can be used to fix relative to the ground or floor. The connecting mechanism 80 includes a connecting end 822, which is connected to the other end of the second door unit 34 of a door group 30 at the rear end of the folding door 100. During the opening or closing of the folding door 100, the connecting end 822 can move relative to the fixing component 70.

[0098] With the above structure, after the first door unit 32 and the second door unit 34 begin to fold, they can move simultaneously toward the fixing component 70 during the folding process, ensuring the smoothness of the folding process. Furthermore, the wiring of the folding door 100 can be arranged in the connecting mechanism 80 to avoid exposure to the external environment.

[0099] In some embodiments, the connecting mechanism 80 includes a third door unit 82 and a fourth door unit 84, the third door unit 82 being rotatably connected to the fourth door unit 84, and both the third door unit 82 and the fourth door unit 84 being slidably connected to the first guide member 10; the third door unit 82 includes a connecting end 822, and the end of the fourth door unit 84 facing away from the third door unit 82 is rotatably connected to the fixing component 70.

[0100] Specifically, both the third door unit 82 and the fourth door unit 84 can include rectangular door frame structures. In the same door group 30, the first door unit 32 is closer to the drive assembly 60 than the second door unit 34. The second door unit 34 at the rear end of the door group 30 of the folding door 100 can be rotatably connected to the body 52 of the same sliding fit assembly 50 with the third door unit 82. The third door unit 82 and the body 52 can be rotatably connected to each other by a hinge. All the first door units 32, second door units 34, third door units 82 and fourth door units 84 have the same shape and size, so that when the folding door 100 is opened, all the first door units 32, second door units 34, third door units 82 and fourth door units 84 are folded together, making the overall structure of the folding door 100 compact when opened.

[0101] In other embodiments, the first gate unit 32, the second gate unit 34, the third gate unit 82, and the fourth gate unit 84 may also have different dimensions, for example, when the fourth guide segment 46 is not parallel to the first guide segment 12 (see...). Figure 5 The lengths of the third gate unit 82 and the fourth gate unit 84 can both be less than the length of the first gate unit 32.

[0102] In some embodiments, when the folding door 100 is closed, the third door unit 82 and the fourth door unit 84 of the connecting mechanism 80 form a preset angle of less than 180°.

[0103] With the above structure, when the folding door 100 starts to open, the door assembly 30 at the rear end of the folding door 100 pushes the connecting mechanism 80 so that the third door unit 82 and the fourth door unit 84 fold. The third door unit 82 and the fourth door unit 84 of the connecting mechanism 80 form a preset angle of less than 180°, and the resistance generated when the third door unit 82 and the fourth door unit 84 fold is small.

[0104] In other embodiments, after the folding door 100 is closed, the included angle between the third door unit 82 and the fourth door unit 84 of the connecting mechanism 80 can also be 180°.

[0105] In some embodiments, the fixing component 70 includes a post 74 and a guardrail 72, with a connecting end 822 movable relative to the post 74; the guardrail 72 is connected to the post 74 and is located on the side of the second guide section 14 opposite to the steering member 20.

[0106] During the folding process of the folding door 100, the connecting end 822 of the connecting mechanism 80 can move toward the column 74 so that the door assembly 30 closest to the fixed component 70 can move toward the column 74.

[0107] Through the above structure, the guardrail 72 can protect the folding space of the folding door 100, so as to prevent people or objects from accidentally entering the folding space of the folding door 100 and reduce the possibility of the folding door 100 being disturbed by the outside world during the folding process.

[0108] In this embodiment, the column 74 may include a cuboid-like structure fixed to the ground, and the fourth door unit 84 may be rotatably connected to the column 74 via a rotating shaft. The guardrail member 72 may include two interconnected gate-like structures, one of which is connected to the column 74, with the column 74 located in the middle of the gate-like structure; the other gate-like structure is connected to one side of the gate-like structure and is located on the side of the second guide section 14 facing away from the fourth guide section 46.

[0109] In some other embodiments, the fixing component 70 may include other structures, such as a door frame structure fixed to the ground or base plate; the guardrail 72 may also include other structures, such as an arc-shaped sheet structure; the connecting mechanism 80 may also include other structures, such as a telescopic plate structure, i.e., one plate is fixed to the post 74 and another plate can extend or retract relative to the plate.

[0110] It is understood that those skilled in the art can configure the fixing component 70 as any structure that is fixed relative to the ground or base plate based on the content disclosed in the embodiments of this utility model; the connecting mechanism 80 can be any structure that has the function of moving between the fixing component 70 and the door assembly 30, and has the connecting function when the door assembly 30 moves toward or away from the fixing component 70.

[0111] Please see Figure 17 After the door assembly 30 is folded, the other end of the first door unit 32 and the other end of the second door unit 34 of each door assembly 30 slide into the second guide section 14, and the steering fitting 36 of each door assembly 30 slides into the fourth guide section 46. The first door unit 32 and the second door unit 34 of all door assemblies 30 are folded together, so that the folding door 100 has a compact structure and occupies less space after being retracted.

[0112] In some embodiments, all the first door units 32 and the second door units 34 have the same shape and size. After the door assembly 30 is retracted, the first door units 32 and the second door units 34 are neatly folded together, making the structure of the folding door 100 more compact.

[0113] In some other embodiments, the first gate unit 32 and the second gate unit 34 may also have different shapes and sizes depending on actual needs.

[0114] Please see Figure 18 After the door assembly 30 unfolds, the steering mating parts 36 of each door assembly 30 slide from the fourth guide section 46 through the connecting guide section 42 and the guide member 20 into the third guide section 44. The first door unit 32 and the second door unit 34 of each door assembly 30 unfold, and all door assemblies 30 are arranged along the first guide member 10 to prevent the door assemblies 30 from deviating from the first guide member 10. All door assemblies 30 are arranged in a straight line along the straight first guide member 10, making the overall structure of the folding door 100 more compact.
