[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0037] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0038] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0039] Telescopic sliding doors are widely used in the management of passages due to their simple structure and small footprint. The prior art provides an aluminum telescopic sliding door, which is composed of multiple movable door bodies, and each door body can be telescopically expanded or closed. However, the telescopic sliding door provided in the prior art has upper and lower beams of door rows made of metal aluminum. When the door row group is retracted, multiple door rows will be suspended. If the number of door rows set in the telescopic sliding door is too large, the weight of the suspended door row will be too large, and the telescopic sliding door will be deformed. In addition, if multiple door rows are set, when the telescopic sliding door is expanded, due to the overall weight and deformation problems, the telescopic sliding door cannot work smoothly and stably.

[0040] Based on this, the length design of this telescopic sliding door is limited. In actual use, when the length of the channel is too long, this telescopic sliding door cannot meet actual needs. The existence of this problem limits the promotion and use of telescopic sliding doors, resulting in the inability to use telescopic sliding doors in complex environments.

[0041] Figure 1 It is a schematic diagram of the overall structure of the telescopic sliding door provided by the utility model in an expanded state; Figure 2 yes Figure 1 Top view of the telescopic sliding door; Figure 3 It is a schematic diagram of the overall structure of the telescopic sliding door provided by the utility model in a retracted state.

[0042] See also Figures 1 to 3 The embodiment of the utility model provides a telescopic sliding door, which includes at least two sliding door assemblies 10, each of which includes a head component 100 and a door row group 200. Figure 1Taking the sliding door assembly 10 on the middle right side as an example, the first door row of the door row group 200 is fixedly connected to the head component 100, and the rear door row of the door row group 200 is connected to the head component 100 of the adjacent sliding door assembly 10. In other words, the rear end of the door row group 200 is connected to the head component 100 connected thereto.

[0043] It should be noted that at least two sliding door assemblies 10 means that the telescopic sliding door may include two sliding door assemblies 10 or include multiple sliding door assemblies 10 connected end to end. It is easy to understand that when multiple sliding door assemblies 10 are connected end to end, the two adjacent sliding doors can be connected through the connecting assembly 300. In other words, the door row group 200 and the adjacent head component 100 are connected through the connecting assembly 300. It should also be noted that one connecting assembly 300 or multiple connecting assemblies 300 can be set between two adjacent sliding door assemblies 10. The connecting assembly 300 can be located at least one of the upper, lower and side of the head component 100. When there are at least two connecting assemblies 300, the connecting assemblies 300 are arranged at intervals, which can enhance the firmness of the connection between the head component 100 and the adjacent door row group 200. At the same time, more connecting assemblies 300 can provide more media for the transmission of force, so that the force transmission between the adjacent sliding door assemblies 10 is smoother and more stable. The specific adaptive selection can be made according to the actual situation.

[0044] It should also be noted here that in the embodiments of the present invention, the deployment direction of the telescopic sliding door is used as a reference. Specifically, the "head" or "tail" in this article is based on the deployment direction. The side facing the deployment direction is the head, and the side away from the deployment direction is the tail. It should be noted that the definitions of head and tail here are only used as a reference for the purpose of clarity in the embodiments of the present invention, and are not used as a specific limitation on the components in the embodiments of the present invention.

[0045] The fixed connection method can be a fastening connection achieved by fasteners such as screws or bolts, can be a method of mutual clamping of buckles and slots, or can be through welding or riveting. There are many ways of fixed connection, and the embodiments of the utility model will not list them one by one here. Specifically, it can be adaptively selected according to actual conditions.

[0046] See also Figures 1 to 3It can be understood that the telescopic sliding door provided in the embodiment of the utility model can break the limitation of the length of the telescopic sliding door in the prior art by setting at least two interconnected sliding door assemblies 10, and solve the problem of the length limit of aluminum materials. When the channel is long, a plurality of sliding door assemblies 10 connected end to end can be set, and the weight of the telescopic sliding door can be dispersed by means of a plurality of head components 100, so as to avoid deformation problems of the telescopic sliding door due to weight concentration and excessive length. Based on this, the service life of the telescopic sliding door can be improved, and the telescopic sliding door can be applied to complex working environments, which is conducive to the promotion and use of telescopic sliding doors.

[0048] In an optional embodiment of the present utility model, see Figures 4 to 6 The connecting assembly 300 includes a first connecting member 311, a second connecting member 312 and a rotating component 313. The first connecting member 311 and the second connecting member 312 are rotatably connected via the rotating component 313. Specifically, one of the first connecting member 311 and the second connecting member 312 is disposed on the tailgate row, and the other of the first connecting member 311 and the second connecting member 312 is disposed on the nose component 100 adjacent to the tailgate row.

[0049] In the optional embodiment of the present utility model, continue to refer to Figures 4 to 6 The rotating component 313 includes a pivot shaft 3134, one of the first connecting member 311 and the second connecting member 312 includes two first axial holes arranged at intervals, and the other of the first connecting member 311 and the second connecting member 312 includes a second axial hole, and the second axial hole is adapted to the spacing between the two first axial holes. During assembly, the second axial hole is suitable for being clamped between the two first axial holes, and the two first axial holes are coaxial with the second axial hole. By allowing the rotating component 313 to pass through the two first axial holes and the second axial holes, the rotating connection between the first connecting member 311 and the second connecting member 312 can be achieved. It can be understood that the first connecting member 311 and the second connecting member 312 can both rotate relative to the rotating connection point. One of the first connecting member 311 and the second connecting member 312 is fixedly connected to the tailgate row of the door row group 200, and the other of the first connecting member 311 and the second connecting member 312 is fixedly connected to the head component 100. The fixed connection method can be a fastening connection achieved by fasteners such as screws or bolts, or by welding or riveting, etc. Specifically, it can be adaptively selected according to actual conditions.

[0050] See also Figure 5 and Figure 6 It can be understood that the telescopic sliding door provided by the embodiment of the utility model is provided with a first connecting member 311, a second connecting member 312 and a rotating component 313, so that the first connecting member 311 and the second connecting member 312 can be rotated to each other through the rotating component 313. In this way, during the movement of the telescopic sliding door, the dynamic difference between the front and rear sliding door components 10 can be balanced through the connecting component 300. In other words, when one of the sliding door components 10 vibrates during the movement, the connecting component 300 connected thereto can allow the sliding door component 10 to rotate slightly relative to the rotating component 313, thereby offsetting the vibration of the sliding door component 10. In this way, the sliding door component 10 can be prevented from transmitting its own vibration to the adjacent sliding door component 10, thereby avoiding cross vibration caused by mutual influence between multiple sliding door components 10, improving the stability and smoothness of the telescopic sliding door during movement, and improving the life of the telescopic sliding door.

[0051] Figure 7 is another structural schematic diagram of the connection assembly 300 provided by the utility model; Figure 8 yes Figure 7 Axle-side schematic diagram of the middle connection assembly 300.

[0052] See also Figure 7 and Figure 8 In an optional embodiment of the utility model, the rotating component 313 includes a first rotating shaft 3131, a second rotating shaft 3132 and a connecting member 3133. The first rotating shaft 3131 is arranged on the first connecting member 311, the second rotating shaft 3132 is arranged on the second connecting member 312, one end of the connecting member 3133 is sleeved on the first rotating shaft 3131, and the other end of the connecting member 3133 is sleeved on the second rotating shaft 3132. The connecting member 3133 is rotatably matched with the first connecting member 311 and the second connecting member 312.

[0053] In this embodiment, the first connecting member 311 and the second connecting member 312 can be obtained by splicing a plurality of splicing plates, and the first rotating shaft 3131 and the second rotating shaft 3132 can be respectively embedded between the splicing plates. Taking the first connecting member 311 as an example, the first connecting member 311 includes a bottom plate and two side plates, and the two side plates are arranged at both ends of the bottom plate. The first rotating shaft 3131 is arranged between the two side plates. In other words, the first connecting member 311 is parallel to the bottom plate, and the connecting member 3133 is provided with a corresponding shaft hole for being sleeved on the first rotating shaft 3131. The connecting member 3133 can rotate relative to the first rotating shaft 3131, and the second connecting member The cooperation between 312 and the connecting member 3133 is similar to the above-mentioned first connecting member 311, and will not be repeated here. It can be understood that by setting the first rotating shaft, the second rotating shaft and the connecting member 3133, based on the rotational cooperation among the three, any one of the first connecting member 311 and the second connecting member 312 can have a range of up and down movement relative to the other. In other words, the first connecting member 311 can move up and down relative to the second connecting member 312. In actual applications, between two adjacent sliding door assemblies 10 connected by the connecting assembly 300, any one of them can have space for up and down movement relative to the other.

[0054] In an optional embodiment of the present utility model, the telescopic sliding door further includes a connecting plate 320, see Figure 6 One end of the connecting plate 320 is fixedly connected to the connecting assembly 300, and the other end of the connecting plate 320 is fixedly connected to the tailgate row of the door row group 200, or the other end of the connecting plate 320 is fixedly connected to the head component 100 adjacent to the tailgate row at that location. In other words, the end of the connecting plate 320 facing away from the connecting assembly 300 is disposed on one of the door row group 200 and the head component 100 adjacent to the door row group 200, and is fixedly connected thereto. Figure 5 and Figure 6 It can be understood that the telescopic sliding door provided by the embodiment of the utility model can extend the length of the connecting component 300 by setting the connecting plate 320. When the positions where the connecting components 300 are installed in two adjacent sliding door components 10 are far apart, the length of the connecting component 300 can be extended by setting the connecting plate 320, thereby avoiding secondary processing or redesign of the connecting component 300, which can reduce the difficulty of manufacturing the connecting component 300 and reduce the manufacturing cost of the connecting component 300.

[0055] In an optional embodiment of the present invention, the connecting plate 320 includes a first connecting portion 321 and a second connecting portion 322. The first connecting portion 321 and the second connecting portion 322 are independent parts. Figure 6The first connection portion 321 and the second connection portion 322 are perpendicular to each other, and the first connection portion 321 and the second connection portion 322 are fixedly connected, the first connection portion 321 is fixedly connected to one of the first connection member 311 and the second connection member 312 of the connecting assembly 300, the second connection portion 322 is arranged on one of the tailgate row and the head component 100 adjacent to the tailgate row, and is fixedly connected thereto, and the second connection portion 322 is arranged on the side of the tailgate row or the head component 100 away from the connecting assembly 300.

[0056] In some cases, the first connection part 321 and the second connection part 322 may also be an integrated part, which can reduce the number of parts and simplify the assembly relationship. In an optional embodiment of the utility model, the first connection part 321 may also be fixedly connected to a part fixedly connected to the second connection part 322, that is, the first connection part 321 may also be fixedly connected to one of the door row group 200 and the head part 100 adjacent to the door row group 200. Specifically, it can be adaptively selected according to actual conditions.

[0057] See also Figure 6 It can be understood that the telescopic sliding door provided by the embodiment of the utility model is provided with a first connecting portion 321 and a second connecting portion 322 which are perpendicular to each other, and the second connecting portion 322 is provided on one of the tailgate row and the head component 100 adjacent to the tailgate row. Taking the second connecting portion 322 being provided on the tailgate row as an example, the connection between the connecting plate 320 and the tailgate row can be made more firm, and the high pair between the tailgate row and the fastener can be transformed into the low pair between the connecting plate 320 and the tailgate row, that is, the force transmission path between the connecting plate 320 and the tailgate row is changed from the rod transmission of the fastener to the surface transmission of the second connecting portion 322, so that the force transmission is more dispersed and uniform, the durability of the connecting plate 320 is improved, the damage of the connecting plate 320 due to stress concentration is avoided, the service life of the connecting plate 320 is improved, and the replacement frequency of the connecting plate 320 is reduced. The effect of the second connecting portion 322 being provided on the head component 100 is similar to that of the head component 100, which will not be described in detail herein.

[0058] In an optional embodiment of the present invention, the connecting plate 320 may also include only the first connecting portion 321, that is, the connecting plate 320 is a separate flat plate. In this case, the connecting plate 320 is arranged on one of the tailgate row and the head component 100 adjacent to the tailgate row, and is fixedly connected thereto. At the same time, the connecting plate 320 is fixedly connected to the connecting assembly 300. This can reduce the number of parts and simplify the assembly relationship. Specifically, an adaptive selection can be made according to actual conditions.

[0059] Fig. 9 yes Figure 1 Schematic diagram of the local enlarged structure at point C in the middle.

[0060] In an optional embodiment of the present utility model, see Fig. 9 The connecting component 300 is also located on the side of the head component 100 facing the adjacent sliding door component 10, and is located at the lower end of the head component 100. On the basis of the aforementioned embodiment, this can enhance the firmness of the connection between the head component 100 and the adjacent door row group 200. At the same time, force can be transmitted from the upper and lower ends of the head component 100 at the same time to avoid rollover caused by uneven pulling, thereby ensuring the stability of the connection between the head component 100 and the adjacent door row group 200.

[0061] In an optional embodiment of the present utility model, see Figure 4 The head component 100 includes a driving member 110 and a head body 120. The driving member 110 is provided on the head body 120. The head body 120 is fixedly connected to the door row 210. The driving member 110 is used to drive the head body 120 to drive the door row group 200 to move along a preset direction. In an optional embodiment of the utility model, the driving member 110 can be provided only in the sliding door assembly 10 at the head of the telescopic sliding door, that is, the telescopic sliding door is provided with only one driving member 110, which can reduce the manufacturing cost of the telescopic sliding door; in some cases, some telescopic sliding doors can be selected from a plurality of telescopic sliding doors, and the driving member 110 can be adaptively provided in the selected telescopic sliding doors. Specifically, the adaptive selection can be made according to actual needs, which will not be described in detail herein.

[0062] It should be noted here that the aforementioned preset direction refers to the moving direction of the telescopic sliding door set according to actual needs. This direction can be adaptively selected according to actual conditions, and the embodiment of the utility model does not make specific limitations on this.

[0063] See also Figures 1 to 4 It can be understood that the telescopic sliding door provided in the embodiment of the utility model can provide a power source for the movement of the telescopic sliding door by setting a driving member 110, thereby improving the automation of the telescopic sliding door; by setting a head body 120, it can support the door row group 200, thereby avoiding problems such as center of gravity shift or deformation of the door row group 200 due to being too long.

[0064] Continue reading Figures 1 to 4 The door row group 200 includes a plurality of door rows 210, and the plurality of door rows 210 are slidably connected in sequence along the length direction of the door row group 200, wherein the first door row is connected to the head body 120, and the tail door row is connected to the head body 120 of the adjacent sliding door assembly 10, so as to form a telescopic sliding door in which the plurality of sliding door assemblies 10 are connected end to end. In the expanded state, the plurality of door rows 210 can form a straight-line structure to close the passage. In the retracted state, the plurality of door rows 210 overlap with each other, so as to reduce the occupation of the passage space by the telescopic sliding door.

[0065] In an optional embodiment of the present invention, the telescopic sliding door also includes a door frame assembly, which includes a front door frame and a rear door frame. The front door frame and the rear door frame are both arranged on the moving path of the telescopic sliding door. The front door frame and the rear door frame are spaced apart along the length direction of the telescopic sliding door to limit the moving path of the telescopic sliding door. In other words, the telescopic sliding door moves between the front door frame and the rear door frame to achieve closing or opening of the passage.

[0066] The rear door frame is slidably matched with the sliding door assembly 10 at the rear of the telescopic sliding door. Figures 1 to 3 The rear column frame of the tailgate row is arranged on the side of the rear door frame away from the front door frame. The rear door frame is a frame-type structure. The rear column frame of the tailgate row extends in a direction perpendicular to the moving direction of the telescopic sliding door, and its extension length is not less than the length of the rear door frame in this direction. In this way, the rear column frame of the tailgate row can be limited to the side of the rear door frame away from the front door frame through the rear door frame. At the same time, the height of the remaining part of the door row 210 is set lower than the height of the door frame of the rear door frame. In this way, the tailgate row can move relatively in the door frame of the rear door frame, that is, the sliding cooperation between the aforementioned rear door frame and the sliding door assembly 10 at the rear of the telescopic sliding door is realized. During the expansion and movement process of the telescopic sliding door, the rear door frame can play a limiting role, that is, provide a fixed point for the telescopic sliding door to assist the expansion process of the door row group 200.

[0067] It should be noted that the height of the other door row groups 200 of the telescopic sliding door and the corresponding door frame columns are less than the height of the rear door frame door frame, and the other door frames extend in a direction perpendicular to the moving direction of the telescopic sliding door, and their extension length is less than the length of the inner frame of the rear door frame in this direction. Figure 3 When the telescopic sliding door is in the process of contraction, part of the telescopic sliding door can be moved to the side of the rear door frame away from the front door frame to reduce the occupation of the passage space.

[0069] In an optional embodiment of the utility model, the telescopic sliding door also includes a limit switch assembly 400, which is arranged in at least one of the two adjacent sliding door assemblies 10. The limit switch assembly 400 is electrically connected to the driving member 110 in the adjacent sliding door assembly 10, and is used to detect the position information of the two adjacent sliding door assemblies 10. The control component can control the start and stop of the adjacent driving member 110 based on the position information of the sliding door assembly 10.

[0070] See also Fig.10The limit switch assembly 400 includes a limit switch 410 and a limit plate 420 for triggering the opening and closing of the limit switch 410. The limit switch 410 is arranged at the connection between two adjacent sliding door assemblies 10 and one of the door rows 210 adjacent to the tailgate row of the previous door row group 200. The limit plate 420 is arranged at the connection between two adjacent sliding door assemblies 10 and the other of the door rows 210 adjacent to the tailgate row of the previous door row group 200. The limit switch 410 is electrically connected to the driving member 110 of the head component 100 adjacent to the door row group 200. The limit switch 410 sends the position information of the door row group 200 based on the contact between the limit switch 410 and the limit plate 420. It should be noted here that the above-mentioned connection can refer to the head component 100 or the tailgate row fixedly connected to the head component 100, which can be adaptively adjusted according to actual conditions.

[0071] Specifically, taking the example that the limit switch 410 is arranged at the rear part of the tailgate row and the limit plate 420 is arranged on the door row 210 connected to the tailgate row, when the door row group 200 shrinks, the door row 210 connected to the tailgate row can slide toward the direction of the tailgate row, and then, the limit plate 420 can contact the contact of the limit switch 410 to send out the position information of the door row 210 connected to the tailgate row. The limit switch 410 can be a travel switch, a two-dimensional matrix position sensor, a contact position sensor, etc., and specifically, it can be adaptively selected according to actual conditions.

[0072] In some embodiments of the utility model, the limit switch 410 can be set on the head component 100 adjacent to the door row group 200, and the limit plate 420 is set on the door row group 200. The position settings of the limit switch 410 and the limit plate 420 can be flexibly designed according to actual conditions, and the embodiments of the utility model are no longer listed one by one here.

[0073] Continue reading Fig.10 The limit plate 420 includes a support portion 421 and a contact portion 422, and the support portion 421 and the contact portion 422 are independent parts. One end of the support portion 421 is arranged at one of the door row group 200 and the head component 100 adjacent to the door row group 200, and the other end of the support portion 421 is fixedly connected to the contact portion 422, and the contact portion 422 is suitable for contacting the contact of the limit switch 410. The fixed connection method is described above and will not be repeated here. In some cases, the support portion 421 and the contact portion 422 can also be an integrated part, so that the number of parts can be reduced and the assembly relationship can be simplified. Specifically, new selections can be adapted according to actual conditions.

[0074] Taking the travel switch as an example, the travel switch is arranged on the column of the tailgate row close to the adjacent head body 120. At the same time, the travel switch is electrically connected to the driving member 110 on the head body 120, and the contact portion 422 is suitable for contacting the contact of the travel switch. Specifically, taking two sliding door assemblies 10 as an example, when the first sliding door assembly 10 (the front sliding door assembly 10) is unfolded, its driving member 110 drives the head body 120 to first drive the door row group 200 of the sliding door assembly 10 to unfold. When the door row group 200 is fully unfolded, that is, when the contact portion 422 is disconnected from the travel switch, the second sliding door assembly 10 is opened. The driving member 110 of the first sliding door assembly 10 (the rear sliding door assembly 10) starts to drive the corresponding head body 120 to move. At this time, the driving member 110 of the first sliding door assembly 10 and the driving member 110 of the second sliding door assembly 10 work simultaneously to keep the first sliding door assembly 10 and the second sliding door assembly 10 moving simultaneously. When the door row group 200 of the second sliding door assembly 10 is fully unfolded, that is, when the head assembly 100 of the first sliding door assembly 10 reaches the unfolding end, the driving member 110 of the first sliding door assembly 10 and the driving member 110 of the second sliding door assembly 10 stop simultaneously.

[0075] During the retraction process, the driving member 110 of the first sliding door assembly 10 is started first to push the door row group 200 of the first sliding door assembly 10 to retract. When the door row group 200 of the first sliding door assembly 10 is fully retracted, that is, when the contact portion 422 contacts the contact of the travel switch, the driving member 110 of the second sliding door assembly 10 is started to push the door row group 200 of the second sliding door assembly 10 to start retracting. At this time, the head components 100 of the front and rear sliding door assemblies 10 move at the same time until the telescopic sliding door reaches the retraction end point, and all the driving members 110 stop at the same time. It should be noted here that a limit magnet can be set at the retraction end point. When the head component 100 of the first sliding door assembly 10 contacts the limit magnet, the telescopic sliding door can be prompted to stop all the driving members 110.

[0076] It should also be noted here that there are many ways to detect that the head component 100 of the first sliding door assembly 10 has reached the end point of the deployment. For example, by setting a limit magnet at the end point of the deployment, when the head body 120 of the first sliding door assembly 10 touches the limit magnet, all driving components 110 are commanded to stop working; the above-mentioned detection method can also be achieved by detecting the moving time and moving distance of the first sliding door assembly 10, or by detecting the deployment state of the second sliding door assembly 10. There are many ways to determine whether the telescopic sliding door is fully deployed. Specifically, adaptive selection can be made according to actual conditions, and the embodiments of the utility model will not be described one by one here.

[0077] Similarly, when the first sliding door assembly 10 is fully unfolded, there are many ways to start the driving member 110 of the second sliding door assembly 10. In addition to being based on the aforementioned contact position sensor, it can also be based on a proximity position sensor, such as an electromagnetic position sensor, a photoelectric position sensor, a differential transformer position sensor, an eddy current position sensor, a capacitive position sensor, a reed switch position sensor, a Hall position sensor, etc.; similar to the foregoing, the starting method of the driving member 110 of the second sliding door assembly 10 can also be achieved by detecting the moving time and moving distance of the first sliding door assembly 10. In the above case, the limit switch assembly 400 can be set only on one of the two adjacent sliding door assemblies 10. Specifically, it can be adaptively selected according to actual conditions.
