[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0021] The following detailed description, in conjunction with all the accompanying drawings, uses specific embodiments to illustrate a steering mechanism 100 and a folding door 1000 provided in this application.

[0022] Please refer to the following: Figures 1 to 3 One embodiment of this utility model discloses a steering mechanism 100, applied to a folding door 1000. The folding door 1000 includes the steering mechanism 100 and a door assembly 200. The door assembly 200 includes a first door unit 210 and a second door unit 220. One end of the first door unit 210 is rotatably connected to one end of the second door unit 220. The first door unit 210 and the second door unit 220 can be folded or unfolded to realize the opening or closing of the folding door 1000.

[0023] In some embodiments, the steering mechanism 100 includes a steering member 10 and a steering mating member 20. The steering member 10 has a guide groove 102. The steering mating member 20 includes a body 22 and a rotation guide 24. The body 22 is used to connect to the first door unit 210 or the second door unit 220. The rotation guide 24 is rotatably connected to the body 22. During the opening of the folding door 1000, when the rotation guide 24 passes through the guide groove 102, the rotation guide 24 engages with the groove wall of the guide groove 102, so that the first door unit 210 and the second door unit begin to fold.

[0024] With the above structure, during the opening of the folding door 1000, the steering engagement 20 passes through the steering engagement 10, and the steering engagement 10 and the steering engagement 20 cooperate to trigger the first door unit 210 and the second door unit 220 to start folding. No greater resistance is generated when the first door unit 210 and the second door unit 220 start folding, that is, no greater pushing force is required to make the first door unit 210 and the second door unit 220 start folding, so as to ensure the smoothness of the folding process of the folding door 1000.

[0025] Specifically, the steering component 10 may include a structure for changing the direction of movement of the steering mating component 20. For example, the steering component 10 may have an arc-shaped guide groove 102. The steering mating component 20 may include a rotating wheel. When the steering mating component 20 is engaged with the steering component 10, the rotating wheel is located in the guide groove 102 and abuts against the groove wall of the guide groove 102 to trigger the first door unit 210 or the second door unit 220 to turn, so that the first door unit 210 and the second door unit 220 begin to fold or unfold.

[0026] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the rotating guide 24 includes a rotating shaft 242 and a collar 244, the body 22 includes a shaft assembly 222, the shaft assembly 222 is sleeved on the upper end of the rotating shaft 242, the rotating shaft 242 is rotatably connected to the shaft assembly 222, and the collar 244 is sleeved on the lower end of the rotating shaft 242.

[0027] With the above structure, when the rotating guide 24 passes through the guide groove 102, the rotating shaft 242 and the groove wall of the guide groove 102 generate rolling friction, which reduces the wear of the rotating shaft 242 and the groove wall of the guide groove 102 and improves the durability of the steering mechanism 100.

[0028] Specifically, the rotating shaft 242 may include a cylindrical structure, and the axis of rotation of the rotating shaft 242 is perpendicular to the horizontal plane; the shaft assembly 222 may include a cylindrical structure, and the rotating shaft 242 and the shaft assembly 222 may be rotatably connected by two bearings, one bearing being located at the upper end of the shaft assembly 222 and the other bearing being located at the lower end of the shaft assembly 222; the collar 244 may also include a cylindrical structure.

[0029] The collar 244 can be made of a flexible material, such as rubber or silicone; or it can be made of a rigid material, such as plastic or metal.

[0030] In other embodiments, the rotation guide 24 may also include other structures, such as a block structure or a cylindrical structure for contacting the steering member 10 and causing deflection.

[0031] In some embodiments, the steering mating member 20 further includes a steering wheel 26 connected to the body 22, and the steering wheel 26 and the rotation guide member 24 are located on opposite sides of the body 22.

[0032] With the above structure, the steering wheel 26 and the rotation guide 24 are located on opposite sides of the main body 22, so that the steering wheel 26 and the rotation guide 24 can simultaneously support the opposite sides of the main body 22, thereby reducing swaying and making the main body 22 more stable during movement.

[0033] Specifically, the main body 22 can be connected to the lower side of the second door unit 220. The main body 22 can be located at the end of the second door unit 220 facing the first door unit 210. The main body 22 can include a trapezoidal plate structure. The rotation axis of the rotating guide 24 can be set perpendicular to the horizontal plane. The steering wheel 26 can rotate relative to the ground, and the steering wheel 26 can also rotate relative to the lower side of the main body 22.

[0034] In some embodiments, the guide groove 102 is arc-shaped and the steering member 10 is arc-shaped, with the arc of the guide groove 102 being the same as that of the steering member 10.

[0035] With the above structure, the guide groove 102 is arc-shaped, making it easier for the steering component 20 to enter and pass through the guide groove 102, reducing the possibility of the steering component 20 getting stuck in the guide groove 102. The steering component 10 is arc-shaped, and the arc of the guide groove 102 is the same as the arc of the steering component 10, making the steering component 10 easier to manufacture.

[0036] Specifically, in this embodiment, the guide groove 102 can have a structure similar to an arc shape.

[0037] In other embodiments, the guide groove 102 may also be a straight line or an "S" shaped structure.

[0038] Please see Figure 5 and Figure 6 In some embodiments, the steering mechanism 100 further includes a first guide member 30, which includes a first guide segment 32 and a second guide segment 34 connected to each other; the steering member 10 is located at the connection between the first guide segment 32 and the second guide segment 34 and is located on one side of the first guide member 30.

[0039] With the above structure, the first guide member 30 can be used to guide the first door unit 210 and the second door unit 220 of the door group 200. During the opening of the folding door 1000, when the steering engagement member 20 passes the steering member 10, the steering member 10 and the steering engagement member 20 cooperate to trigger the first door unit 210 and the second door unit 220 of the door group 200 to start folding. After the first door unit 210 and the second door unit 220 start folding, under the guidance of the second guide section 34, the first door unit 210 and the second door unit 220 can run smoothly to ensure the smoothness of the folding process of the first door unit 210 and the second door unit 220.

[0040] Specifically, the first guide member 30 may include a guiding structure, such as a guide rail or guide groove 102; wherein the first guide segment 32 and the second guide segment 34 may be integrally formed; or the first guide segment 32 and the second guide segment 34 may be disassembled or spliced ​​together. The first guide member 30 may be straight or curved with a certain curvature.

[0041] The steering wheel 26 is located on the side of the body 22 facing away from the first guide member 30, and the rotating guide member 24 is located on the side of the body 22 facing the first guide member 30.

[0042] In some embodiments, the steering mechanism 100 further includes a second guide 40, which includes a connecting guide section 42 connected to the steering member 10; during the opening of the folding door 1000, the rotating guide 24 can enter the connecting guide section 42 via the guide groove 102.

[0043] With the above structure, after the first door unit 210 and the second door unit 220 begin to fold, the connecting guide section 42 guides the steering engagement 20. As the steering engagement 20 moves along the connecting guide section 42, the included angle between the first door unit 210 and the second door unit 220 decreases, that is, the first door unit 210 and the second door unit 220 can gradually fold; in order to avoid the first door unit 210 and the second door unit 220 getting stuck during the folding process.

[0044] Specifically, in this embodiment, the connecting guide segment 42 can be bent toward the second guide segment 34, that is, the connecting guide segment 42 is arc-shaped, and the center of the connecting guide segment 42 and the second guide segment 34 are located on the same side of the connecting guide segment 42.

[0045] The first guide member 30, the steering member 10, and the second guide member 40 can all be fixed to the ground or the base plate, so that the first guide member 30, the steering member 10, and the second guide member 40 are all located below the door assembly 200.

[0046] In other embodiments, the first guide 30, the steering member 10, 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 30, the steering member 10, and the second guide 40 are located above the door assembly 200; or, the first guide 30, the steering member 10, and the second guide 40 may be arranged vertically to be installed on a vertically arranged wall or other fixed structure.

[0047] In some embodiments, the second guide member 40 further includes a third guide segment 44 and a fourth guide segment 46. The third guide segment 44 is connected to the side of the steering member 10 facing away from the connecting guide segment 42, and the fourth guide segment 46 is connected to the side of the connecting guide segment 42 facing away from the steering member 10. In the direction in which the folding door 1000 opens, the distance between the fourth guide segment 46 and the second guide segment 34 remains consistent.

[0048] With the above structure, after the door assembly 200 is folded, the first door unit 210 and the second door unit 220 in the door assembly 200 are folded together, and the door assembly 200 is located between the fourth guide section 46 and the second guide section 34, so that the fourth guide section 46 and the second guide section 34 can be used to accommodate the folded door assembly 200.

[0049] The third guide section 44, the steering component 10, the connecting guide section 42, and the fourth guide section 46 can all guide the steering mating component 20 so that the steering mating component 20 can move along the third guide section 44 before passing the steering component 10 during the opening of the folding door 1000. As a result, the first door unit 210 and the second door unit 220 in the door assembly 200 can remain relatively stationary, avoiding the simultaneous folding of the entire door assembly 200 and reducing the maximum thrust required by the drive assembly 500.

[0050] In this embodiment, the steering component 10, the connecting guide section 42, the third guide section 44, and the fourth guide section 46 can be integrally formed.

[0051] In some embodiments, the first guide segment 32, the second guide segment 34, the third guide segment 44 and the fourth guide segment 46 are all straight lines, the first guide segment 32 and the second guide segment 34 are located on the same straight line, and the first guide segment 32 is parallel to the third guide segment 44 and the fourth guide segment 46.

[0052] Based on the above structure, the first guide section 32 and the fourth guide section 46 are parallel to each other, and it can be inferred that the second guide section 34 and the fourth guide section 46 are parallel to each other. When the dimensions of each door group 200 of the folding door 1000 are the same, all door groups 200 can be accommodated together between the second guide section 34 and the fourth guide section 46 after folding.

[0053] Specifically, the first guide section 32 and the second guide section 34 can be integrally formed, and the third guide section 44, the steering component 10, the connecting guide section 42 and the fourth guide section 46 are arranged in sequence and integrally formed.

[0054] In other embodiments, the steering member 10 and the connecting guide section 42, the third guide section 44 and the steering member 10, and the connecting guide section 42 and the fourth guide section 46 can also be connected to each other by splicing.

[0055] In other embodiments, the fourth guide segment 46 and the third guide segment 44, the third guide segment 44 and the first guide segment 32, and the fourth guide segment 46 and the first guide segment 32 may be at other angles.

[0056] In some embodiments, the third guide segment 44 has a first guide groove 4402, the connecting guide segment 42 has an arc-shaped second guide groove 4202, and the fourth guide segment 46 has a third guide groove 4602. The first guide groove 4402, the guide groove 102, the second guide groove 4202, and the third guide groove 4602 are connected in sequence. The rotating guide member 24 can move within the first guide groove 4402, the guide groove 102, the second guide groove 4202, and the third guide groove 4602. The guide groove 102 is arc-shaped, and the bending direction of the guide groove 102 is opposite to the bending direction of the second guide groove 4202.

[0057] With the above structure, the rotating guide 24 can move within the first guide groove 4402, the arc-shaped guide groove 102, the second guide groove 4202, and the third guide groove 4602; when the rotating guide 24 moves within the first guide groove 4402, the first door unit 210 and the second door unit 220 remain in an unfolded state, and the included angle between the first door unit 210 and the second door unit 220 is 180° or other preset angle; when the rotating guide 24 moves within the arc-shaped guide groove 102, the first door unit 210 and the second door unit 220 remain in an unfolded state. As folding begins, the angle between the first door unit 210 and the second door unit 220 begins to decrease. When the rotating guide 24 moves within the second guide groove 4202, the first door unit 210 and the second door unit 220 gradually complete folding, and the angle between the first door unit 210 and the second door unit 220 gradually decreases to 0°. When the rotating guide 24 moves within the third guide groove 4602, the folded first door unit 210 and the second door unit 220 are housed between the fourth guide section 46 and the second guide section 34.

[0058] Specifically, the first guide groove 4402, the arc-shaped guide groove 102, 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 102, the second guide groove 4202, and the third guide groove 4602 all face upwards. The collar 244 can extend into the first guide groove 4402, the arc-shaped guide groove 102, the second guide groove 4202, or the third guide groove 4602.

[0059] In other embodiments, the bending direction of the arc-shaped guide groove 102 may also be the same as the bending direction of the second guide groove 4202.

[0060] Please see Figure 7 In some other embodiments, the third guide segment 44 can be a straight track parallel to and conforming to one side of the first guide segment 32. The steering component 10 can include a guide structure with an arc-shaped guide groove 102. The connecting guide segment 42 has an arc-shaped second guide groove 4202; the fourth guide segment 46 has a third guide groove 4602. The central axis of the third guide groove 4602 is parallel to the first guide segment 32, and the width of the third guide groove 4602 gradually increases in the direction away from the connecting guide segment 42. Please refer to [link to relevant documentation]. Figure 8 The central axis of the three guide grooves 4602 is inclined relative to the first guide section 32.

[0061] Please see Figure 9 In some other embodiments, the third guide segment 44, the steering member 10 and the connecting guide segment 42 can also be an integral structure, with the steering member 10 and the connecting guide segment 42 forming a straight line structure. One end of the integral formed by the steering member 10 and the connecting guide segment 42 is connected to the third guide segment 44, and the other end of the integral formed by the steering member 10 and the connecting guide segment 42 is connected to the fourth guide segment 46.

[0062] Please refer to Figure 10 In some other embodiments, both the steering member 10 and the connecting guide section 42 can be arc-shaped track structures, and the bending directions of the steering member 10 and the connecting guide section 42 are the same; the second guide groove 4202 is also arc-shaped, and the bending direction of the arc-shaped guide groove 102 is the same as the bending direction of the second guide groove 4202.

[0063] Please refer to Figure 11In some other embodiments, the third guide segment 44 can be a straight track parallel to the first guide segment 32 and attached to one side of the first guide segment 32. The steering component 10 can include a guide structure with an arc-shaped guide groove 102. The connecting guide segment 42 has an arc-shaped second guide groove 4202. The fourth guide segment 46 includes a straight track and has a third guide groove 4602. The central axis of the third guide groove 4602 is inclined relative to the first guide segment 32.

[0064] Please refer to the following: Figure 1 , Figure 12 and Figure 13 The folding door 1000 may also include a sliding engagement assembly 400, a drive assembly 500, a fixing assembly 600, and a connecting mechanism 700.

[0065] A sliding engagement assembly 400 is mounted on the first guide member 30. The door assembly 200 is rotatably connected to the sliding engagement assembly 400, and the door assembly 200 is slidably connected to the first guide member 30 via the sliding engagement assembly 400. A drive assembly 500 is connected to the door assembly 200 and is used to drive the first door unit 210 and the second door unit 220 to fold or unfold. A connecting mechanism 700 is connected between the fixing assembly 600 and the door assembly 200.

[0066] When there is one door group 200, the side of the second door unit 220 facing away from the first door unit 210 is rotatably connected to a sliding fit assembly 400, and the side of the first door unit 210 facing away from the second door unit 220 is rotatably connected to a drive assembly 500.

[0067] In some embodiments, when there are two or more door groups 200, in two adjacent door groups 200, the other end of the second door unit 220 of one door group 200 is rotatably connected to the other end of the first door unit 210 of the other door group 200.

[0068] The sliding fit assembly 400 is slidably connected to the first guide member 30. The other end of the second door unit 220 of a door group 200 and the other end of the first door unit 210 of an adjacent door group 200 are respectively rotatably connected to a sliding fit assembly 400.

[0069] With the above structure, the sliding engagement component 400 at the connection between two adjacent door groups 200 can support both door groups 200 at the same time; so that fewer sliding engagement components 400 can support the entire door group 200, thereby reducing the resistance when the folding door 1000 unfolds or retracts.

[0070] A sliding fit assembly 400 can be installed at the connection point of two adjacent door groups 200; the second door unit 220 of the door group 200 at the rear end of the folding door 1000 is rotatably connected to a sliding fit assembly 400; the first door unit 210 of the door group 200 at the front end of the folding door 1000 is rotatably connected to a drive assembly 500. When the folding door 1000 is open, the sliding fit assembly 400 located at the connection point of the two adjacent door groups 200 is located below the two adjacent door groups 200.

[0071] Furthermore, the sliding engagement assembly 400 may include a main body 420, a guide engagement member 440, and a support member 460. The guide engagement member 440 is mounted on the main body 420 and slidably connected to the first guide member 30. The support member 460 is mounted on the main body 420 and supports the main body 420. The guide engagement member 440 includes a first guide wheel 442 and a second guide wheel 444, both of which are rotatably connected to the main body 420.

[0072] The first guide wheel 442 extends into the first side guide groove 302, and the second guide wheel 444 extends into the second side guide groove 304.

[0073] Both the first side guide groove 302 and the second side guide groove 304 can be blind grooves with a rectangular or U-shaped cross-section. The first side guide groove 302 and the second side guide groove 304 can guide the sliding fit assembly 400 through the first guide wheel 442 and the second guide wheel 444, respectively.

During the opening or closing of the folding door 1000, the connecting end 722 can move relative to the fixing component 600.

[0086] With the above structure, after the first door unit 210 and the second door unit 220 begin to fold, they can simultaneously move towards the fixing component 600 during the folding process, ensuring the smoothness of the folding process. Furthermore, the wiring of the folding door 1000 can be arranged within the connecting mechanism 700 to avoid exposure to the external environment.

[0087] In some embodiments, the connecting mechanism 700 includes a third door unit 720 and a fourth door unit 740, the third door unit 720 being rotatably connected to the fourth door unit 740, and both the third door unit 720 and the fourth door unit 740 being slidably connected to the first guide member 30; the third door unit 720 includes a connecting end 722, and the end of the fourth door unit 740 facing away from the third door unit 720 is rotatably connected to the fixing component 600.

[0088] Specifically, both the third door unit 720 and the fourth door unit 740 can include rectangular door frame structures. In the same door group 200, the first door unit 210 is closer to the drive assembly 500 than the second door unit 220. The second door unit 220 of the door group 200 at the rear end of the folding door 1000 can be rotatably connected to the body 420 of the same sliding fit assembly 400 with the third door unit 720. The third door unit 720 and the body 420 can be rotatably connected to each other by a hinge. All the first door units 210, second door units 220, third door units 720 and fourth door units 740 have the same shape and size, so that when the folding door 1000 is opened, all the first door units 210, second door units 220, third door units 720 and fourth door units 740 are folded together, making the overall structure of the folding door 1000 compact when opened.

[0089] In other embodiments, the first gate unit 210, the second gate unit 220, the third gate unit 720 and the fourth gate unit 740 may have different dimensions.
