[0001] The utility model relates to the technical field of mobile doors, in particular to a flexible track and a sliding structure of a folding door. Background Art

[0002] In various sliding door systems, the sliding of the door body is usually realized by the sliding cooperation between the pulley assembly and the track. For sliding door systems such as folding doors and in-bus sliding doors, since the door body needs to have a deflection amount on the side of the track, the corresponding track is designed with an arc-shaped bend. In order to form such a track structure, the existing tracks are manufactured and formed separately for the straight section and the arc section and then docked. Due to various factors such as processing accuracy and the mismatch of the installation structure, there are always some deviations in the connection between the straight section and the arc section. When the pulley slides to the connection position of the two, there will be a certain degree of jamming, which undoubtedly affects the smoothness of the sliding of the pulley assembly.

[0030] The present utility model provides the following description with reference to the drawings to help a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.

[0031] In the description of the present utility model, orientation descriptions are involved, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, 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 therefore should not be construed as a limitation to the present utility model.

[0032] It should be understood that when an element (for example, the first element) is "connected" to another element (for example, the second element), the element can be directly connected to the other element, or there can be an intermediate element (for example, the third element) between the element and the other element.

[0033] An embodiment of the present utility model provides a flexible track, as Figure 1 and Figure 2 shown, including a track body 100 made of a flexible material. The flexible material includes, but is not limited to, plastics, rubbers, silicones, etc., which enables the track body 100 to be bent. The track body 100 includes an integrally formed straight section 110 and an arc section 120. The straight section 110 extends linearly, and the arc section 120 extends in an arc. A part of the track body 100 can be bent to form the arc section 120. A sliding portion 101 for slidingly cooperating with a pulley is provided on the track body 100. The sliding portion 101 extends along the extending direction of the track body 100, and naturally also extends from the straight section 110 to the arc section 120.

[0034] In this embodiment, since the track body 100 is made of a flexible material and the straight section 110 and the arc section 120 are integrally formed, the track body 100 can be bent to form the arc section 120. In this way, the butt joint between the straight section 110 and the arc section 120 is more accurate and the transition is smoother. When the pulley assembly slides to the connection position between the straight section 110 and the arc section 120, the pulley assembly can pass through more smoothly and is not easily stuck, which improves the smoothness of the sliding of the pulley assembly. At the same time, since the track body 100 is flexible, it can undergo elastic deformation. When there is a certain position deviation of the pulley of the pulley assembly, the track body 100 can maintain contact with the pulley through deformation, thereby ensuring the sliding fit between the pulley and the sliding part 101.

[0035] In some embodiments, the sliding part 101 is arranged on the side surface of the track body 100 and protrudes outward in an arc shape. Correspondingly, when the pulley cooperates with the sliding part 101, it is also located on the side surface of the track body 100. Since the sliding part 101 protrudes in an arc shape, the smoothness of its surface is increased, making it easier for the pulley to slide on the sliding part 101.

[0036] In this embodiment, a groove adapted to the sliding part 101 can be provided on the circumferential surface of the pulley, and the sliding part 101 can be inserted into the groove. By the adaptation between the sliding part 101 and the groove, the position deviation of the pulley is restricted, so as to maintain sliding along the extension direction of the track body 100.

[0037] In some other embodiments, the sliding part is a sliding groove provided on the surface of the track body, and a part of the pulley can be embedded in the sliding groove and slide along the sliding groove.

[0038] The sliding groove can be set to be arc-shaped and adapted to the pulley to increase smoothness, making it easier for the pulley to slide in the sliding groove.

[0039] In some embodiments, two sliding parts 101 are provided and are respectively located on both sides of the track body 100. Therefore, both the left side and the right side of the track body 100 can be in sliding fit with the pulley, making its versatility stronger. Correspondingly, the pulley assembly is provided with two groups of pulleys, and the two groups of pulleys are respectively in sliding fit with the two sliding parts 101. By the two groups of pulleys, the pulley assembly can be restricted from deviating from the track body 100, so that the pulley assembly maintains a sliding connection with the track body 100.

[0040] In some embodiments, a clamping portion 102 is provided at the bottom of the track body 100. The clamping portion 102 is used to install and secure the track body 100. The clamping portion 102 can be clamped and secured to the installation location of the track body 100, thereby achieving the installation and fixation of the track body 100. The use of a clamping method facilitates the installation and removal of the track body 100. The installation location can be a designated location on a mounting base, a designated location on a cabinet, or a designated location on a wall, etc., where the track body 100 is to be installed.

[0041] Furthermore, the clamping portion 102 includes a protrusion 103 protruding toward the bottom of the rail body 100, and a plurality of undercuts 104 can be set on both sides of the protrusion 103. A fixing groove can be set at the installation position, and the inner wall of the fixing groove is provided with a buckle groove adapted to the undercut 104. The protrusion 103 is inserted into the fixing groove, and the undercut 104 is hooked in the buckle groove on the inner wall of the fixing groove, thereby realizing the clamping and fixing of the clamping portion 102.

[0042] In other embodiments, a concave snap-in groove is provided at the bottom of the rail body, and a snap-in piece adapted to the snap-in groove is provided at the installation position of the rail body. The snap-in piece is snapped into the snap-in groove, thereby fixing the rail body through the cooperation between the snap-in piece and the snap-in groove.

[0043] Due to the use of a snap-on connection method, the track body is easy to install and disassemble. The installation position can be a designated position on the mounting base, a designated position on the cabinet, or a designated position on the wall, etc., where the track body needs to be installed.

[0044] In some embodiments, the top surface of the rail body 100 is provided with a plurality of mounting holes 105 that pass through the rail body 100. Screws, bolts and other connecting parts can be passed through the mounting holes 105, and the connecting parts are then fixed to the installation position of the rail body 100 to further fix the rail body 100 in the installation position and improve the stability of the installation.

[0045] Furthermore, a mounting groove 106 is provided on the top surface of the track body 100, and a mounting hole 105 is provided on the bottom wall of the mounting groove 106. When the screws, bolts and other connecting parts are installed in place, the heads of the screws, bolts and other connecting parts can be received in the mounting groove 106, so that they do not protrude from the track body 100, making it difficult for the pulley to touch the screws, bolts and other connecting parts, thereby ensuring the smoothness of the pulley sliding.

[0046] In some embodiments, according to actual needs, the rail body 100 may include two arc segments 120 and one straight segment 110 , and the straight segment 110 may be located between the two arc segments 120 .

[0047] The embodiment of the present invention provides a folding door sliding structure, such as Figures 3-5As shown, it includes a pulley assembly 200, a buffer assembly 300, and the flexible track of any of the above embodiments. For the specific description of the flexible track, reference can be made to the above embodiments and will not be elaborated here. The pulley assembly 200 includes a support rod 210 and a pulley 220 provided at one end of the support rod 210. The other end of the support rod 210 is used to connect to the door body. The pulley 220 is in sliding fit with the sliding part of the track body, enabling the pulley assembly 200 to slide along the track body, and thus can drive the door body to slide. The buffer assembly 300 is provided on one side of the arc section 120. When the pulley assembly 200 slides to the arc section 120, the buffer assembly 300 is used to provide a buffering force to the pulley assembly 200, so that the door body can be slowly closed or opened, avoiding the door body touching the door frame or the cabinet body at a relatively high speed.

[0048] In some embodiments, there are two sliding parts provided and are respectively located on both sides of the track body. Correspondingly, as Figure 4 shown, two sets of pulleys 220 are provided on the support rod 210. The two sets of pulleys 220 are respectively located on both sides of the track body and are in sliding fit with the two sliding parts. By the two sets of pulleys 220, the pulley assembly 200 can be restricted from deviating from the track body, and thus the pulley assembly 200 can maintain a sliding connection with the track body.

[0049] In some embodiments, as Figure 5 and Figure 6 shown, the buffer assembly 300 includes a stopper 310 and a buffer 320. One end of the stopper 310 is provided with a first rotating shaft 312, and the other end is a free end 311 that can rotate around the first rotating shaft 312. The first rotating shaft 312 can be fixed at a designated installation position. A rotating hole for inserting the first rotating shaft 312 is provided on the stopper 310. The first rotating shaft 312 can rotate in the rotating hole, and the entire stopper 310 can rotate around the axis of the first rotating shaft 312. The buffer 320 is rotationally connected to the stopper 310. As the stopper 310 rotates, the position of the buffer 320 will also change. A stop rod 230 is provided on the support rod 210, and a sliding groove 313 is provided on the side of the free end 311 of the stopper 310. The free end 311 of the stopper 310 can rotate to a waiting position close to the straight section 110, and naturally can also rotate to other positions away from the waiting position.

[0050] When the free end 311 of the stopper 310 is in the waiting position, if the pulley assembly 200 slides from the straight section 110 to the arc section 120, the stop rod 230 of the pulley assembly 200 can enter the sliding groove 313 and drive the free end 311 of the stopper 310 to rotate in a direction away from the straight section 110. During the process of the free end 311 of the stopper 310 rotating in a direction away from the straight section 210, the buffer 200 provides a buffering force to the stopper 310, and the stopper 310 then provides a buffering force to the pulley assembly 200, thereby enabling the pulley assembly 200 to move slowly and realizing the buffering of the door body.

[0051] During the process of the pulley assembly 200 sliding from the arc segment 120 to the straight segment 110, the stop lever 230 of the pulley assembly 200 drives the free end 311 of the stopper 310 to rotate towards the waiting position. When the free end 311 of the stopper 310 rotates to the waiting position, the stop lever 230 of the pulley assembly 200 disengages from the sliding groove 313, and the pulley assembly 200 is separated from the stopper 310, and the pulley assembly 200 can continue to slide along the straight segment 110. Thus, during the process of the pulley assembly 200 sliding from the straight segment 110 to the arc segment 120, the buffer assembly 300 can buffer the pulley assembly 200, and when the pulley assembly 200 slides from the arc segment 120 to the straight segment 110, the buffer assembly 300 does not affect the sliding of the pulley assembly 200.

[0052] Furthermore, the sliding groove 313 has two side walls, one side wall is close to the straight segment 110, and the other side wall is relatively far from the straight segment 110. The side wall of the sliding groove 313 far from the straight segment 110 extends into the moving path of the stop lever 230. When the stop lever 230 slides with the pulley assembly 200, the stop lever 230 will touch the side wall of the sliding groove 313 far from the straight segment 110. When the free end 311 of the stopper 310 is in the waiting position, if the pulley assembly 200 slides from the straight segment 110 to the arc segment 120, the stop lever 230 of the pulley assembly 200 will touch the side wall of the sliding groove 313 far from the straight segment 110, and then the stop lever 230 can enter the sliding groove 313, and the stop lever 230 can drive the stopper 310 to rotate.

[0053] As Figure 6 shown, the left side wall of the sliding groove 313 protrudes significantly. When the pulley assembly 200 slides from the straight segment 110 to the arc segment 120, the stop lever 230 will cross the right side wall of the sliding groove 313, and then touch the left side wall of the sliding groove 313, and then enter the sliding groove 313.

[0054] In some embodiments, as Figure 5 and Figure 6 shown, the buffer assembly further includes an elastic member 330. The elastic member 330 is connected to the stopper 310 and is used to apply a force to the stopper 310 to keep the stopper 310 in the waiting position. In this way, the stopper 310 can wait for the arrival of the pulley assembly and then provide a buffer force, ensuring that the buffer assembly can provide a buffer force each time, so that it can be used for a long time.

[0055] In this embodiment, the elastic member 330 can be a spring. One end of it can be rotatably connected to the stopper 310, and the other end can be rotatably connected to the installation position. In this way, during the rotation of the stopper 310, the spring can maintain the connection with the stopper 310.

[0056] In some embodiments, the buffer 320 includes a damping tube 321, a piston rod, and a connector 322. One end of the piston rod extends into the damping tube 321 from the head end of the damping tube 321, and the other end is connected to the connector 322. During the process of the piston rod sliding relative to the damping tube 321, a buffering force can be generated. Since the buffer 320 already belongs to the prior art, the specific structure and principle inside the damping tube 321 will not be elaborated. The connector 322 is rotatably connected to the stopper 310. A second rotating shaft 323 is provided at the tail end of the damping tube 321, and the head end of the damping tube 321 can rotate around the second rotating shaft 323 so that during the rotation of the stopper 310, the buffer 320 can maintain its connection with the stopper 310 and can maintain providing a buffering force along the axial direction of the damping tube 321.

[0057] In this embodiment, the second rotating shaft 323 can be fixed at the installation position. A connection block can be provided at the tail end of the damping tube 321, and a rotating hole adapted to the second rotating shaft 323 is provided on the connection block. The second rotating shaft 323 is inserted into the rotating hole and can rotate in the rotating hole, realizing that the damping tube 321 can rotate around the second rotating shaft 323.

[0058] In some embodiments, as Figure 7 shown, the sliding structure of the folding door further includes a straight-section mounting seat 341 and an arc-section mounting seat 342 docked with the straight-section mounting seat 341. Both the straight-section mounting seat 341 and the arc-section mounting seat 342 are provided with fixing grooves 343. A part of the straight section of the track body is embedded in the fixing groove 343 of the straight-section mounting seat 341, and a part of the arc section of the track body is embedded in the fixing groove 343 of the arc-section mounting seat 342, thereby fixing the track body.

[0059] In this embodiment, the clamping portion at the bottom of the track body can be clamped and fixed in the fixing groove 343. Connecting members such as screws and bolts can be used to pass through the mounting holes on the top surface of the track body, and then the track body is fastened in the fixing groove 343 to improve the stability of the installation of the track body.

[0060] Furthermore, the buffer assembly of the above embodiment can be installed on the arc-section mounting seat 342, and both the first rotating shaft and the second rotating shaft can be fixed on the arc-section mounting seat 342, which makes the overall structure more compact and also facilitates the installation of the entire sliding structure of the folding door.

[0061] Even further, as Figure 2 shown, an upper cover 350 is provided on the arc-section mounting seat 342. The upper cover 350 covers the stopper 310, the buffer 320, and the elastic member 330, playing a role in dust protection for the stopper 310, the buffer 320, and the elastic member 330.

[0062] As Figure 8As shown, the sliding structure of the folding door in this embodiment can be applied to the cabinet body 400, and the cabinet body 400 is provided with a foldable door body 410. The track body, the pulley assembly 200 and the buffer assembly 300 can all be fixed on the top of the cabinet body 400. The strut of the pulley assembly 200 is rotatably connected to the door body 410. As the pulley assembly 200 slides on the track body, the door body 410 can be closed and folded open.
