The door body is slidably mounted on the door frame via two parallel guide rails, which provide support and guidance for the door body. The smoothness of the door's operation is limited by the parallelism of the two guide rails. This is particularly true for sliding door assemblies with large spans and travels, which place stricter demands on the assembly of the door frame, door body, and guide rails. This can easily lead to assembly errors in the sliding door assembly. These errors can cause abnormal wear between the door body and the door frame, and between the door body and the guide rails, significantly reducing the smoothness and lifespan of the sliding door assembly.

[0052] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 3 The up and down directions are consistent with the Figure 3 The left and right directions are consistent with the Figure 3 The projection direction itself is consistent.

[0053] Traditional movable door assemblies have two parallel guide rails on the door frame. The two guide rails are located on either side of the door body, and the two sides of the door body are slidably mounted on the two guide rails. The two guide rails play a guiding and supporting role. The parallelism of the installation of the two guide rails not only affects the smoothness or smoothness of the door body's operation, but also affects the life of the door body. For doors with a movable span of more than 500mm, the smoothness or smoothness of the movable door's operation is more easily subject to the parallelism of the installation of the guide rails on both sides, and the assembly and processing requirements of the movable door assembly are higher, resulting in increased difficulty in assembling the movable door assembly. When the movable door assembly has an assembly error, it not only affects the smoothness or smoothness of the door body's operation, but also increases the pressure between the door body and the door frame, and between the door body and the guide rails, causing abnormal wear, which greatly reduces the smoothness or smoothness of the operation and the life of the movable door assembly.

[0054] like Figures 1 to 8As shown, this embodiment provides a movable door assembly, including a door frame 11, a guide seat 12, a connecting frame 13, a door body 14, and a driver 15. The door frame 11 is used to support the weight of the guide seat 12, the driver 15, and the door body 14. The driver 15 and the guide seat 12 are installed on the door frame 11. The driver 15 is used to drive the door body 14 to move in a horizontal direction. In this embodiment, the driver 15 is used to drive the door body 14 to move in a horizontal straight line in the front-to-back direction. The door frame 11 is provided with a support portion 113, and the support portion 113 is used to support the door body 14. The connecting frame 13 is rotatably and slidably installed on the guide seat 12. The connecting frame 13 is rotatably installed on the guide seat 12 and can slide along the direction of the rotation axis. The sliding direction of the connecting frame 13 is parallel to the rotation axis of the connecting frame 13. The connecting frame 13 is horizontally slidably mounted on the guide base 12 from front to back, and the connecting frame 13 can rotate relative to the guide base 12 about a horizontal straight line in the front-to-back direction. The connecting frame 13 can drive the door body 14 to slide, and the connecting frame 13 and the door body 14 can rotate together about the connecting frame 13. The door body 14 has a connecting portion 144 and an abutting portion 145. The connecting portion 144 is used to connect to the connecting frame 13. The support portion 113 and the abutting portion 145 are both flat. The support portion 113 is located on the rotation path of the abutting portion 145 of the door body 14. When the door body 14 is slidably mounted on the door frame 11 in the horizontal direction, the abutting portion 145 is located above the support portion 113 of the door frame 11 and abuts against the support portion 113. The connecting portion 144 of the door body 14 is movably connected to the connecting frame 13 so that the abutting portion 145 of the door body 14 abuts against the support portion 113 from top to bottom. The door body 14 can rotate and slide relative to the connecting frame 13, so that the abutting portion 145 of the door body 14 can remain abutted against the support portion 113 under the action of gravity. The driver 15 is transmission-connected to the connecting frame 13 to drive the connecting frame 13 to slide, and the connecting frame 13 can swing relative to the driver 15 around the rotation axis of the connecting frame 13. The output end of the driver 15 can push the connecting frame 13 to slide linearly, and the connecting frame 13 can swing relative to the output end of the driver 15, thereby avoiding the connection between the connecting frame 13 and the driver 15 being rigidly connected and causing the connecting frame 13 to be unable to rotate.

[0055] In this way, the movable door assembly of this embodiment guides the door body 14 through a single guide seat 12, and supports the door body 14 through the support part 113 of the door frame 11, thereby realizing the separation of guidance and support. Compared with the installation method of using two guide rails to guide and support the door body 14, it completely solves the problem of running smoothness caused by the non-parallelism of the two guide rails, and avoids the smoothness of the door body 14 being subject to the installation parallelism of the two guide rails. Especially for movable door assemblies with large spans and large strokes, it greatly reduces the difficulty of assembly, making the assembly of movable door assemblies simpler.

[0056] At the same time, the connecting frame 13 of this embodiment can rotate relative to the guide seat 12, avoiding abnormal wear between the connecting frame 13 and the guide seat 12 due to the guide seat 12 having to bear the load of the connecting frame 13 and the door body 14. In addition, the door body 14 is movably connected to the connecting frame 13, which can reduce the production and processing accuracy and assembly accuracy requirements of the connecting frame 13 and the door body 14 compared to the traditional rigid connection. When there are errors in production and processing accuracy and assembly accuracy, the relative movement of the door body 14 and the connecting frame 13 can be used to make the abutting portion 145 of the door body 14 abut against the support portion 113 only under the action of gravity, avoiding the positive pressure of the abutting portion 145 of the door body 14 on the support portion 113 of the door body 14 due to assembly errors being greater than the total gravity of the door body 14 and the connecting frame 13, thereby avoiding abnormal wear between the door body 14 and the door frame 11, greatly reducing the smoothness and life of the movable door assembly.

[0057] Optionally, the movable door assembly further includes a connecting rod 16 mounted on the connecting frame 13 and a limiting member 17 mounted on the connecting rod 16. The connecting rod 16 and the limiting member 17 together enclose a sliding gap 18. The limiting member 17 is threadedly connected to the lower end of the connecting rod 16. The limiting member 17 is a screw and a limiting washer mounted on the screw. The sliding gap 18 is formed between the limiting washer and the lower end of the connecting rod 16. A first connecting hole is provided at the connecting portion 144, and the first connecting hole passes through the connecting portion 144 from top to bottom. The connecting portion 144 is sleeved on the connecting rod 16 and / or the limiting member 17 through the first connecting hole and can slide in the sliding gap 18. The connecting portion 144 can also be installed in the sliding gap 18 in an up-and-down sliding manner. A first movable gap 19 is defined between the connecting rod 16 and / or the limiting member 17 and the inner wall of the first connecting hole. In this way, the connection part 144 of the door body 14 slides up and down in the sliding gap 18 and the connection part 144 of the door body 14 swings relative to the connecting rod 16 and the limit member 17, so as to realize a flexible gap connection between the door body 14 and the connecting frame 13, so that the door body 14 and the connecting frame 13 are movably connected, and the connecting rod 16 and the limit member 17 only bear the vertical load of the door body 14. The door body 14 can slide and swing within a certain range relative to the connecting frame 13, avoiding abnormal wear of the guide rod and the cylinder 151 due to assembly errors, reducing the difficulty of assembly, and improving the smoothness of the operation of the door body 14.

[0058] Furthermore, the movable door assembly also includes a connecting seat 20 installed on the door body 14. The connecting seat 20 is installed on the upper end surface of the door body 14 by screws. The connecting seat 20 is provided with a second connecting hole connected to the first connecting hole. The second connecting hole passes through the connecting seat 20 from top to bottom. The first connecting hole is located directly below the second connecting hole. The diameter of the first connecting hole is smaller than the second connecting hole. The upper end of the connecting rod 16 is connected to the connecting frame 13. The lower end of the connecting rod 16 is slidably arranged in the second connecting hole and connected to the limit member 17. There is a second movable gap 21 between the connecting rod 16 and the inner wall of the second connecting hole. The connecting rod 16 can also slide up and down in the second connecting hole, and can also swing relative to the door body 14 in the direction close to or away from the inner wall of the second connecting hole to ensure that the abutting portion 145 of the door body 14 abuts against the support portion 113 of the door frame 11. In order to reduce the weight of the door body 14 , the door body 14 needs to be relatively light and thin, but this will greatly reduce the connection strength of the door body 14 . In this embodiment, a connecting seat 20 is provided to improve the connection strength between the connecting frame 13 and the door body 14 .

[0059] In other embodiments, the connecting frame 13 and the door body 14 can also be connected by a telescopic rod and a universal joint installed on the telescopic rod. The telescopic rod is installed on the connecting frame 13. The universal joint is connected to the door body 14.

[0060] In one embodiment, the actuator 15 includes a cylinder 151 with a push rod, a floating joint 152 with a floating rod mounted on the push rod, a connecting sheet metal 153, and first and second buffer pads 154, 155, both mounted on the floating rod. One end of the floating joint 152 is fixedly connected to the push rod of the cylinder 151, while the other end is spaced apart and fitted with the first and second buffer pads 154, 155. The push rod of the cylinder 151 drives the floating joint 152 to move horizontally back and forth, which in turn drives the door body 14 to move horizontally back and forth. The first and second buffer pads 154, 155 are spaced apart along the direction of movement of the push rod to cushion the horizontal movement of the cylinder 151. The connecting sheet metal 153 includes a first plate 156 connected to the connecting frame 13 and a second plate 157 with a third connecting hole. The first and second plates 156, 157 are perpendicular to each other, and the first plate 156 is fixedly connected to the connecting frame 13 by screws. The second plate 157 is mounted on the floating rod through the third connecting hole and positioned between the first and second buffer pads 154 and 155. The connecting sheet metal 153 is capable of some deformation. The end of the floating joint 152, distal from the push rod, is inserted into the third connecting hole. The first and second buffer pads 154 and 155 are positioned on either side of the second plate 157. The floating rod and the third connecting hole are loosely fitted. The deformation of the connecting sheet metal 153 and the loose fit between the floating rod and the connecting sheet metal 153 allow the connecting sheet metal 153 to rotate within a certain range relative to the floating rod, thereby allowing the connecting frame 13 to rotate around the guide seat 12. In this way, the connecting frame 13 achieves a flexible, gap-free connection with the cylinder 151 through the connecting sheet metal 153. This prevents abnormal wear between the guide seat 12, cylinder 151, and connecting frame 13 due to assembly errors, thereby improving the reliability of the movable door assembly.

[0061] Optionally, in order to prevent the door body 14 from moving upward over a large distance due to vibration of the processing equipment or other external forces, the door body 14 of this embodiment has two limiting modes.

[0062] Key References Figure 4 and Figure 6The first limiting method is: the door body 14 includes a door panel 141 and a first support seat 142 provided on the door panel 141. The first support seat 142 is made of sintered steel to improve strength. The first support seat 142 is provided with a first limiting groove 143, and the abutting portion 145 is located on the inner wall of the first limiting groove 143, specifically the abutting portion 145 is located on the top wall of the first limiting groove 143. The support portion 113 of the door frame 11 is loosely matched with the first limiting groove 143, and the distance in the up-down direction of the first limiting groove 143 is greater than the thickness of the support portion 113 of the door frame 11 in the up-down direction. There is a small distance between the support portion 113 of the door frame 11 and the bottom wall of the first limiting groove 143 to avoid friction between the support portion 113 and the bottom wall of the first limiting groove 143, thereby reducing the sliding friction of the door body 14. The first limiting groove 143 is used to realize the range of movement of the door panel 141 up and down, and to prevent the door body 14 from moving upward and separating from the door frame 11.

[0063] The second limiting method is as follows: the door frame 11 includes a door frame and a second support seat provided on the door frame. The second support seat is made of sintered steel to improve strength. The second support seat is provided with a second limiting groove, and the support portion 113 is located on the inner wall of the second limiting groove. The abutment portion 145 of the door body 14 is loosely fitted with the second limiting groove. There is a small distance between the abutment portion 145 of the door body 14 and the top wall of the second limiting groove to avoid friction between the abutment portion 145 and the top wall of the second limiting groove, thereby reducing the sliding friction of the door body 14. The second limiting groove realizes the range of movement of the door panel 141 up and down, preventing the door body 14 from moving upward and separating from the door frame 11.

[0064] Furthermore, when the first limiting method is used, the first support seat 142 includes a first support plate 146 and a first limiting plate 147. The first support plate 146 and the first limiting plate 147 are spaced apart from each other from top to bottom on the door panel 141. The first support plate 146 and the first limiting plate 147 are respectively mounted on the door panel 141 via screws, facilitating assembly, disassembly, and maintenance. A first limiting groove 143 is formed between the first support plate 146 and the first limiting plate 147. The abutment portion 145 is located on the first support plate 146, which abuts the support portion 113 of the door frame 11 from top to bottom.

[0065] When the second limiting method is used, the second support base includes a second support plate and a second limiting plate. The second limiting plate and the second limiting plate are spaced apart from each other from top to bottom on the door frame and are respectively mounted to the door frame with screws, facilitating assembly, disassembly, and maintenance. A second limiting groove is formed between the second limiting plate and the second supporting plate. The support portion 113 is located on the second supporting plate, and the abutment portion 145 of the door body 14 abuts the second supporting plate from top to bottom.

[0066] In one embodiment, the door frame 11 has a first mounting portion 111, a second mounting portion 112, and a doorway 114 formed between the first mounting portion 111 and the second mounting portion 112. The first mounting portion 111 and the second mounting portion 112 are located on the left and right sides of the door frame 11. Support portions 113 are provided on the first mounting portion 111 and the second mounting portion 112, and the support portions 113 are located at the edge of the doorway 114. Abutment portions 145 are provided on the left and right sides of the door body 14, and a connecting portion 144 is located between the two abutment portions 145. There is at least one connecting portion 144. The abutment portion 145 on one side of the door body 14 abuts against the support portion 113 on the first mounting portion 111, and the abutment portion 145 on the other side of the door body 14 abuts against the support portion 113 on the second mounting portion 112. The driver 15 is installed on the first mounting portion 111 or the second mounting portion 112 to drive the door body 14 to cover or move away from the doorway 114. Specifically, the connecting portion 144 is located in the middle area of ​​the door body 14, there are two abutting portions 145 and they are located on the left and right sides of the door body 14, the door frame 11 has two support portions 113 spaced apart from each other from left to right, the two support portions 113 correspond to the two abutting portions 145 one by one, and the movement of the door body 14 relative to the connecting frame 13 causes the two abutting portions 145 of the door body 14 to abut against the two support portions 113 of the door frame 11 respectively. In this way, the driving point of the connecting frame 13 driving the door body 14 to slide is located in the middle position of the door body 14, and the movable connection between the door body 14 and the connecting frame 13 makes the connection between the door body 14 and the connecting frame 13 flexible. The guide seat 12 only bears the axial load of the door body 14 in front and behind, and does not bear the weight of the door body 14 itself or the bending moment generated by the door body 14 itself, thereby improving the smoothness of operation and the life of the guide rod.

[0067] Furthermore, the cylinder 151 of the actuator 15 is positioned parallel to and to one side of the guide base 12, reducing the space occupied by components on the door frame 11 and improving its compactness. In the prior art, the cylinder 151 is typically positioned in the middle of the door panel 141, which balances the forces on the guide rails on both sides of the door body 14. This occupies a larger space and is not suitable for applications with compact structures. This movable door assembly of this embodiment is adaptable to applications with limited space, reducing the number of guide rails while improving the smoothness of operation of large-span movable door assemblies.
