The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0066] See also Figures 1 to 6 , for ease of understanding and explanation, Figure 3 , Figure 4 and Figure 5The first position S1, the second position S2 and the third position S3 are respectively marked in the figure, wherein the first position S1 is a schematic diagram of the position when the door row module 20 slides toward one end of the front frame module 30 (the front end of the door row module 20) to the front frame module 30 (a schematic diagram of the position when the vehicle passage is closed), the second position S2 is a schematic diagram of the position when the door row module 20 slides toward one end of the front frame module 30 to the first middle frame module 40, and the third position S3 is a schematic diagram of the position when the door row module 20 slides toward one end of the front frame module 30 to the second middle frame module 50.

[0067] An embodiment of the present invention provides a sliding door 100, including a guide rail 10, a door row module 20, a front frame module 30, a first middle frame module 40 and a second middle frame module 50. The door row module 20 is installed on the guide rail 10, the front frame module 30, the first middle frame module 40 and the second middle frame module 50 are arranged in sequence along the length direction of the guide rail 10, a vehicle passage 101 is formed between the front frame module 30 and the first middle frame module 40, and a pedestrian passage 102 is formed between the first middle frame module 40 and the second middle frame module 50. The door row module 20 can slide along the guide rail 10 to control the opening and closing of the vehicle passage 101 and the pedestrian passage 102.

[0068] like Figure 1 and Figure 2 As shown, when assembling the sliding door 100, the guide rail 10 can be first installed on the ground, and then the front frame module 30, the first middle frame module 40 and the second middle frame module 50 can be fixed on the wall or the ground, so that the front frame module 30, the first middle frame module 40 and the second middle frame module 50 are arranged in sequence along the length direction of the guide rail 10, and finally the door row module 20 is slidably installed on the guide rail 10, and the assembly of the sliding door 100 can be completed. When the sliding door 100 is assembled, the end of the door row module 20 facing the front frame module 30 can slide back and forth between the first position S1 and the third position S3 to achieve multi-channel coordination and multi-mode operation to meet the use requirements of different scenarios, specifically:

[0069] like Figure 3 As shown, Figure 3 It is a schematic diagram of the state when the door row module 20 slides to the first position S1 toward one end of the front frame module 30. At this time, the vehicle passage 101 is in a closed state, and the pedestrian passage 102 is in an open state, allowing only pedestrians to pass, that is, the pedestrian passage 102 mode is realized.

[0070] like Figure 4 As shown, Figure 4 It is a schematic diagram of the state when the door row module 20 slides to the second position S2 toward one end of the front frame module 30. At this time, the vehicle passage 101 is in an open state and the pedestrian passage 102 is in a closed state. Only vehicles are allowed to pass, that is, the vehicle passage 101 mode is realized.

[0071] like Figure 5 As shown, Figure 5 It is a schematic diagram of the state when the door row module 20 slides to the third position S3 toward one end of the front frame module 30. At this time, the pedestrian passage 102 and the vehicle passage 101 are both in the open state, and both pedestrians and vehicles can pass through, that is, the full channel mode (pedestrian and vehicle diversion mode) is realized.

[0072] In summary, in this embodiment, by sliding the door row module 20 toward one end of the front frame module 30 to different positions, the diversion and isolation of people and vehicles are achieved, thereby improving traffic safety and traffic efficiency. Furthermore, the sliding door 100 has pedestrian channel mode, vehicle channel mode and full channel mode. The user can flexibly adjust the channel mode according to the actual application scenario requirements, realize multi-channel coordination and multi-mode operation, and meet the usage requirements in different scenarios.

[0073] See also Figures 3 to 6 In some embodiments, the sliding door 100 further includes a first side door 60 for controlling the opening or closing of the pedestrian passage. The first side door 60 is disposed on one side of the guide rail 10 and is located between the first middle frame module 40 and the second middle frame module 50. The first side door 60 can be installed on a wall or on the ground. The door row module 20 can cooperate with the first side door 60 to control the opening and closing of the pedestrian passage 102. Specifically:

[0074] like Figure 3 As shown, when the door row module 20 slides to the first position S1 toward one end of the front frame module 30 (at this time, the front end of the door row module 20 is located at the front frame module 30, and the rear end of the door row module 20 is located at the first middle frame module 40), and the first side door 60 is opened, the vehicle passage 101 is closed and the pedestrian passage 102 is opened. At this time, only pedestrians are allowed to pass, that is, the pedestrian passage 102 mode is realized.

[0075] like Figure 4 As shown, when the door row module 20 slides toward one end of the front frame module 30 to the second position S2 (at this time, the front end of the door row module 20 is located at the first middle frame module 40), and the first side door 60 is closed, the vehicle passage 101 is opened and the pedestrian passage 102 is closed. At this time, only vehicles are allowed to pass, that is, the vehicle passage mode is realized.

[0076] like Figure 5 As shown, when the door row module 20 slides toward one end of the front frame module 30 to the third position S3 (at this time, the front end of the door row module 20 is located at the second middle frame module 50), and the first side door 60 is opened, the vehicle passage 101 and the pedestrian passage 102 are both opened, and pedestrians and vehicles can pass through, that is, the full channel mode is realized.

[0077] like Figure 6As shown, when the door row module 20 slides to the first position S1 toward one end of the front frame module 30 and the first side door 60 is closed, the vehicle passage 101 and the pedestrian passage 102 are both closed, and pedestrians and vehicles are prohibited from passing, that is, a fully closed mode (night mode) is achieved.

[0078] Therefore, by cooperating with the first side door 60 through the door row module 20, the sliding door 100 can realize the pedestrian channel 102 mode, the vehicle channel 101 mode, the full channel mode and the fully closed mode, so as to meet the usage requirements in different scenarios, improve the convenience and flexibility of user use, and ensure the safety and reliability of the sliding door 100.

[0079] In some embodiments, the sliding door 100 further includes a second side door 70, which is disposed on a side of the second middle frame module 50 away from the first middle frame module 40; the second middle frame module 50 is provided with a gap 501 (see Figure 1 ), when the second side door 70 is opened, the door row module 20 is allowed to slide over the second middle frame module 50 through the gap 501, and when the second side door 70 is closed, the gap 501 is closed.

[0080] Specifically, when the door row module 20 needs to slide from the first position S1 to the second position S2 or the third position S3, the door row module 20 needs to pass through the second middle frame module 50, so the second side door 70 is configured to be in an open state, allowing the door row module 20 to pass through the second middle frame module 50 and slide to the second position S2 or the third position S3.

[0081] When the door row module 20 slides from the second position S2 or the third position S3 to the first position S1, a larger gap 501 is formed in the middle of the second middle frame module 50. In order to prevent people from entering through the gap 501, the second side door 70 is configured to be closed when the door row module 20 is located in the first position S1, thereby preventing people from entering or exiting the gap 501 and improving the safety and reliability of the sliding door 100.

[0082] In some embodiments, the first side door 60 and the second side door 70 are electric doors, which facilitates automatic control of the opening and closing of the first side door 60 and the second side door 70. For example, the first side door 60 and the second side door 70 can be configured as electric swing doors or electric telescopic doors.

[0083] In some embodiments, the sliding door 100 further includes a controller, which is used to control the movement of the door row module 20 and the opening and closing of the first side door 60 and the second side door 70. Specifically, the controller can receive instructions input by the user, and control the movement of the door row module 20 and the opening and closing of the first side door 60 and the second side door 70 accordingly, thereby realizing flexible switching between different application modes of the sliding door 100. Optionally, the user can input corresponding instructions through a button switch, a remote controller, a mobile phone APP, etc.

[0084] When the user needs to enter the fully closed mode, the controller controls the door row module 20 to slide toward one end of the front frame module 30 to the front frame module 30, and controls the first side door 60 and the second side door 70 to be completely closed, so as to enter the fully closed mode.

[0085] Optionally, the controller can first control the first side door 60 to close to prevent potential safety hazards caused by personnel entering and exiting the first side door 60 during the closing process of the door row module 20. After the first side door 60 is fully closed, the controller controls the door row module 20 and the second side door 70 to close in sequence, and the fully closed mode can be entered.

[0086] When the user needs to enter the pedestrian passage mode, the controller controls the door row module 20 to slide toward one end of the front frame module 30 to the front frame module 30, and controls the second side door 70 to close to prevent safety hazards caused by people entering and exiting from the second side door 70, and finally controls the first side door 60 to open to enter the pedestrian passage mode.

[0087] When the user needs to enter the vehicle passage mode, the controller first controls the second side door 70 to open, and then controls the door row module 20 to slide toward one end of the front frame module 30 to the first middle frame module 40 to enter the vehicle passage mode.

[0088] When the user needs to enter the full channel mode, the controller first controls the second side door 70 to open. After the second side door 70 is fully opened, the controller controls the door row module 20 to slide toward one end of the front frame module 30 to the second middle frame module 50, and finally controls the first side door 60 to open to enter the full channel mode.

[0089] See also Figures 7 to 11 In some embodiments, the sliding door 100 further includes a first driving module 80 and a second driving module 90, the first driving module 80 and the second driving module 90 are spaced apart along the length direction of the guide rail 10, the first driving module 80 includes a first motor 81 and a first gear 82, the first motor 81 is transmission-connected to the first gear 82, the second driving module 90 includes a second motor 91 and a second gear 92, the second motor 91 is transmission-connected to the second gear 92; the door row module 20 includes a door row assembly 21 and a rack 22 disposed at the bottom of the door row assembly 21;

[0090] When the front end of the door row module 20 is located at the front frame module 30, the first motor 81 is started, and the first gear 82 is meshed with the rack 22 to drive the door row module 20 to move away from the front frame module 30, until the rack 22 is meshed with the second gear 92, the second motor 91 is started, and the second gear 92 is meshed with the rack 22 to drive the door row module 20 to continue to move away from the front frame module 30, until the front end of the door row module 20 moves to the first middle frame module 40, and the vehicle passage 101 is opened;

[0091] When the front end of the door row module 20 is located at the front frame module 30, the first motor 81 is started, and the first gear 82 is meshed with the rack 22 to drive the door row module 20 to move away from the front frame module 30, until the rack 22 is meshed with the second gear 92, the second motor 91 is started, and the second gear 92 is meshed with the rack 22 to drive the door row module 20 to continue to move away from the front frame module 30, until the front end of the door row module 20 moves to the second middle frame module 50, and the vehicle passage 101 and the pedestrian passage 102 are both opened;

[0092] When the front end of the door row module 20 is located at the second middle frame module 50, the second motor 91 is started, and the door row module 20 is driven to move toward the front frame module 30 through the meshing transmission of the second gear 92 and the rack 22, until the rack 22 is meshed with the first gear 82, the first motor 91 is started, and the door row module 20 is driven to continue to move toward the front frame module 30 through the meshing transmission of the first gear 82 and the rack 22, until the front end of the door row module 20 moves to the front frame module 30, and the vehicle passage 101 is closed.

[0093] In this way, the dual motors can be used to drive the door row module 20 to move on the guide rail 10, thereby controlling the opening and closing of the vehicle passage 101 and the pedestrian passage 102.

[0094] Optionally, the first drive module 80 and the second drive module 90 can be configured as the same side of the guide rail 10, and the first drive module 80 and the second drive module 90 can be installed on the ground respectively. In addition, the first drive module 80 and the second drive module 90 can also be installed on the first middle frame module 40 and the second middle frame module 50 respectively. Optionally, the first drive module 80 can be arranged on the inner side of the first middle frame module 40, and the second drive module 90 can be arranged on the inner side of the second middle frame module 50, so as to avoid the first drive module 80 and the second drive module 90 from occupying additional space and improve the compactness and neatness of the overall structure. In addition, the first drive module 80 can also be arranged on the front side, rear side and outer side of the first middle frame module 40, and the second drive module 90 can also be arranged on the front side, rear side and outer side of the second middle frame module 50.

[0095] like Fig. 9 and Fig.10 As shown, the door row assembly 21 may include an upper beam 211, a lower beam 212 and a plurality of door panels 210, wherein the plurality of door panels 210 are disposed between the upper beam 211 and the lower beam 212. The rack 22 may be mounted on the bottom of the lower beam 212, and the rack 22 is disposed along the length direction of the bottom of the lower beam 212 and is parallel to the length direction of the guide rail 10. The first gear 82 and the second gear 92 are respectively connected to the first motor 81 and the second motor 91 in a transmission manner and are disposed at the bottom of the door row assembly 21, so that the first gear 82 and the second gear 92 are meshed with the rack 22. The first motor 81 and the second motor 91 are respectively driven to rotate the first gear 82 and the second gear 92, thereby driving the rack 22 to move along the length direction of the guide rail 10, so that the door row module 20 slides along the guide rail 10.

[0096] In some embodiments, the first motor 81 and the second motor 91 adopt gear reduction motors, which will not self-lock. Therefore, in the power-off state, the first gear 82 on the first motor 81 and the second gear 92 on the second motor 91 can be easily rotated under the action of external force. For example, the first gear 82 and the second gear 92 can be rotated manually, so that the door row module 20 can realize the door opening and closing action, ensuring that the door row module 20 can be opened in the event of an unexpected situation, thereby ensuring the safety of the sliding door 100.

[0097] In some embodiments, the first motor 81 and the second motor 91 are both communicatively connected to the controller. Specifically, the controller can be communicatively connected to the first motor 81 and the second motor 91 wirelessly or by wire. The operation of the first motor 81 and the second motor 91 can be controlled by the controller, thereby controlling the opening and closing actions of the door row module 20.

[0098] The controller can receive vehicle passage instructions, vehicle and pedestrian passage instructions and vehicle restriction instructions input by the user. Optionally, the user can input corresponding instructions through a remote control, button switch, mobile phone APP, etc.

[0099] Specifically, when the controller receives a vehicle passage instruction, it can control the vehicle passage 101 to open; when the controller receives a vehicle and pedestrian passage instruction, it can control the vehicle passage 101 and the pedestrian passage 102 to open; when the controller receives a vehicle restriction instruction, it can control the vehicle passage 101 to close.

[0100] When the door row module 20 is at position S1, if the controller receives a vehicle passing instruction, the controller executes the following steps:

[0101] A1. The controller controls the first motor 81 to rotate according to the vehicle passing instruction, and the second motor 91 does not rotate, and limits the power supply to the second motor 91 so that the second gear 92 can rotate under the push of the rack 22. The first gear 82 drives the rack 22 and the door row assembly 21 to move away from the front frame module 30, so that the rack 22 is meshed with the second gear 92;

[0102] Optionally, the controller may limit the power supply to the second motor 91 by limiting the current flowing into the second motor 91, or directly controlling to cut off the power to the second motor 91. Since the power supply to the second motor 91 is limited, the current flowing into the second motor 91 is small, and the electromagnetic force generated by the second motor 91 is small, so that the second gear 92 at the output end of the second motor 91 is in a freely rotatable state, that is, the second gear 92 can rotate under the push of the rack 22.

[0103] In the process of the first motor 81 driving the first gear 82 and driving the rack 22 and the door row assembly 21 to move, the rack 22 will gradually approach the second gear 92 and contact the second gear 92. As the rack 22 continues to move, the rack 22 will push the second gear 92 to rotate, so that the rack 22 can be smoothly embedded in the second gear 92 and mesh with it, thereby reducing the jitter, tooth jumping and jamming of the rack 22 when entering the second gear 92.

[0104] A2. After the rack 22 is meshed with the second gear 92, the controller controls the first motor 81 to stop running, and limits the power supply to the first motor 81 so that the first gear 82 can rotate under the pull of the rack 22; optionally, the controller limits the power supply to the first motor 81 by limiting the current flowing into the first motor 81, or directly controls the first motor 81 to be powered off, at which time the first gear 82 can rotate freely.

[0105] A3. The controller controls the second motor 91 to rotate, and the second gear 92 drives the rack 22 and the door row assembly 21 to continue to move away from the front frame module 30 until the front end of the door row module 20 moves to the first middle frame module 40, and the vehicle passage 101 is opened.

[0106] When the first motor 81 stops running, the controller controls the second motor 91 to rotate. When the second motor 91 drives the second gear 92 to rotate and drives the rack 22 and the door row assembly 21 to continue to move, the rack 22 meshes with the first gear 82 and pulls the first gear 82 to rotate until the rack 22 is separated from the first gear 82. When the rack 22 is separated from the first gear 82, the second gear 92 will continue to drive the rack 22 and the door row assembly 21 to move until the front end of the door row module 20 moves to the first middle frame module 40, and the vehicle passage 101 is opened.

[0107] When the door row module 20 is at position S1, if the controller receives a vehicle or pedestrian passage instruction, the controller executes the following steps:

[0108] B1. The controller controls the first motor 81 to rotate according to the vehicle and pedestrian passage instruction, and the second motor 91 does not rotate, and limits the power supply to the second motor 91 so that the second gear 92 can rotate under the push of the rack 22. The first gear 82 drives the rack 22 and the door row assembly 21 to move away from the front frame module 30, so that the rack 22 is meshed with the second gear 92;

[0109] B2. After the rack 22 is meshed with the second gear 92, the controller controls the first motor 81 to stop running, and limits the power supply to the first motor 81 so that the first gear 82 can rotate under the pull of the rack 22; optionally, the controller limits the power supply to the first motor 81 by limiting the current flowing into the first motor 81, or directly controls the first motor 81 to be powered off, at which time the first gear 82 can rotate freely.

[0110] B3. The controller controls the second motor 91 to rotate, and the second gear 92 drives the rack 22 and the door row assembly 21 to continue to move away from the front frame module 30 until the front end of the door row module 20 moves to the second middle frame module 50, and the vehicle passage 101 and the pedestrian passage 102 are opened.

[0111] When the door row module is in position S3, if the controller receives a vehicle restriction command, the controller executes the following steps:

[0112] C1. The controller controls the second motor 91 to rotate according to the vehicle and pedestrian passage instruction, and the first motor 81 does not rotate, and limits the power supply to the first motor 81 so that the first gear 92 can rotate under the push of the rack 22. The second gear 92 drives the rack 22 and the door row assembly 21 to move toward the front frame module 30, so that the rack 22 is meshed with the first gear 82;

[0113] C2. After the rack 22 is meshed with the first gear 82, the controller controls the second motor 91 to stop running, and limits the power supply to the second motor 91 so that the second gear 92 can rotate under the pull of the rack 22; optionally, the controller limits the power supply to the second motor 91 by limiting the current flowing into the second motor 91, or directly controls the first motor 91 to be powered off, at which time the second gear 92 can rotate freely.

[0114] C3. The controller controls the first motor 81 to rotate, and the first gear 82 drives the rack 22 and the door row assembly 21 to continue to move toward the front frame module 30 until the front end of the door row module 20 moves to the front frame module 30 and the vehicle passage is closed.

[0115] Through the above control method, in the process of the controller controlling the movement of the door row module 22, when the first motor 81 drives the door row assembly 21 to move, the second motor 82 stops running, and when the second motor 82 drives the door row assembly 21 to move, the first motor 81 stops running, ensuring that there is always only one motor driving the door row module 22 to move, avoiding gear jumping, jittering, jamming, abnormal noise and other phenomena caused by speed deviation of the dual motors, and ensuring the smooth operation of the door row module 22.

[0116] In some embodiments, the center distance L between the first gear 82 and the second gear 92 is equal to a multiple of the tooth pitch P of the rack 22. Figure 7 and Figure 8 As shown, the center distance L is the distance between the center of the first gear 82 and the center of the second gear 92 , and the tooth pitch P of the rack 22 is the distance between two adjacent teeth of the rack 22 .

[0117] By setting the center distance L between the first gear 82 and the second gear 92 to an integral multiple of the tooth pitch P, it can be ensured that when the first drive module 80 and the second drive module 90 act on the door row module 20 at the same time, the rack 22 can be precisely meshed with the first gear 82 and the second gear 92 at the same time. In this way, during the sliding process of the door row module 20, the rack 22 can smoothly transition from a state of being meshed with only the first gear 82 or the second gear 92 to a state of being precisely meshed with both the first gear 82 and the second gear 92 at the same time, avoiding tooth jumping, misalignment and jamming during the transmission process, and ensuring stability, reliability and low noise during the transmission process.

[0118] like Fig.10 and Fig.11 As shown, in some embodiments, the first drive module 80 also includes a first base 83, the first motor 81 is installed on the first base 83, the second drive module 90 includes a second base 93, and the second motor 91 is installed on the second base 93; the first base 83 and the second base 93 are spaced apart along the length direction of the guide rail 10, and at least one of the first base 83 and the second base 93 is provided with an adjustment hole 830, and the adjustment hole 830 is used to adjust the installation position of the first drive module 80 or the second drive module 90, so that the center distance L between the first gear 82 and the second gear 92 is equal to a multiple of the tooth pitch P of the rack 22, thereby avoiding the jamming phenomenon of the door row module 20 during the sliding process and reducing the noise during the transmission process.

[0119] The first base 83 and the second base 93 may have the same structure, both of which are roughly plate-shaped structures, and the adjustment hole 830 may be a strip hole, the length direction of which is parallel to the length direction of the guide rail 10, so as to adjust the distance between the first drive module 80 and the second drive module 90. The first base 83 and the second base 93 may be fixed by fasteners such as bolts and screws, thereby fixing the first drive module 80 and the second drive module 90.

[0120] Taking the adjustment hole 830 on the first base 83 as an example, when it is necessary to adjust the center distance between the first gear 82 and the second gear 92, it is only necessary to loosen the fasteners used to fix the first base 83, and then the installation position of the first base 83 can be fine-tuned so that the center distance L between the first gear 82 and the second gear 92 is equal to a multiple of the tooth pitch P of the rack 22. The adjustment process is convenient and quick.

[0121] In some embodiments, the first driving module 80 also includes a first chassis 84, which is disposed in the middle of the first base 83, and the adjustment hole 830 is opened at the periphery of the first base 83 to prevent the adjustment hole 830 from being blocked by the first chassis 84, thereby improving the convenience of adjustment.

[0122] The first motor 81 is installed in the first chassis 84, which can protect the first motor 81 from damage, improve the safety of use and the neat appearance. The first gear 82 is located outside the first chassis 84 to facilitate engagement with the rack 22. Optionally, the output shaft of the first motor 81 can pass through the first chassis 84 and be connected to the first gear 82 in transmission.

[0123] Optionally, the first chassis 84 includes a box body 840 and a box door 841 covering one side of the box body 840, and the box door 841 can be detachably mounted on the box body 840 for easy inspection and maintenance. A notch 8410 is provided on the box door 841, and the output shaft of the first motor 81 can pass through the notch 8410 and be transmission-connected with the first gear 82 outside the first chassis 84.

[0124] The second driving module 90 further includes a second chassis 94 , and the second motor 91 is installed in the second chassis 84 . The structure of the second chassis 94 may be the same as that of the first chassis 94 , which will not be described in detail herein.

[0125] Optionally, the first driving module 80 further includes a motor base 85 , which is fixedly mounted in the first chassis 84 , and the first motor 81 is mounted on the motor base 85 , and the motor base 85 plays a role in fixing and supporting the first motor 81 .

[0126] Optionally, the first drive module 80 also includes a connecting shaft 86, a bearing 87 and a bearing seat 88. The output shaft of the first motor 81 is connected to the first gear 82 through the connecting shaft 86. The bearing seat 88 is fixedly mounted on the first base 83 and is located on the outside of the first chassis 84. The bearing is installed in the bearing seat 88. The connecting shaft 86 is passed through the bearing 87. The bearing 87 can improve the rotation efficiency between the connecting shaft 86 and the bearing seat 88, and provide stable support for the connecting shaft 86, thereby improving transmission accuracy and stability.

[0127] Optionally, the first drive module 80 further includes an electric control board 89 , which is electrically connected to the controller and can receive control signals corresponding to the controller to control the stopping, acceleration and deceleration of the first motor 81 , and limit the power supply to the first motor 81 .

[0128] The above mainly introduces the specific structure of the first driving module 80. It should be understood that the specific structure of the second driving module 90 may be the same as that of the first driving module 80, and will not be repeated here.

[0129] See also Figures 12 to 16 In some embodiments, the first middle frame module 40 includes a frame 41 and a pressure wheel mechanism 42, the pressure wheel mechanism 42 is installed on the frame 41, the pressure wheel mechanism 42 is located above the door row assembly 21 and is used to limit the displacement of the door row assembly 21 in the vertical direction. When the bottom rack 22 of the door row assembly 21 moves toward the first gear 82 and engages with the first gear 82, the pressure wheel mechanism 42 can be against the top surface of the door row assembly 21, that is, the pressure wheel 420 is against the top surface of the upper beam 211, so as to limit the vertical jumping of the door row assembly 21.

[0130] In the process of the second driving module 90 driving the door row assembly 21 to operate, when the rack 22 at the bottom of the door row assembly 21 gradually approaches the first gear 82 and meshes with the first gear 82 for operation, since the first gear 82 is located at the bottom of the door row module 20, the door row module 20 will be subjected to an upward force from the first gear 82. In order to prevent the door row module 20 from being subjected to the force of the first gear 82 and causing upward jumping, tooth jumping and shaking, in this embodiment, a pressure wheel is arranged on the frame 41 Mechanism 42, during the meshing operation of the rack 22 at the bottom of the door row assembly 21 and the first gear 82, the pressure wheel 420 of the pressure wheel mechanism 42 will abut against the top surface of the door row assembly 21, thereby limiting the upward movement of the door row assembly 21, preventing the door row assembly 21 from jumping, jumping teeth and shaking during operation, ensuring that the rack 22 at the bottom of the door row assembly 21 is accurately meshed with the first rack 22 under the pressure of the pressure wheel 420, thereby ensuring the stability and reliability of the door row module 20 during the sliding process along the guide rail 10.

[0131] It can be understood that the second middle frame module 50 also has the above-mentioned pressure wheel mechanism 42. The pressure wheel mechanism 42 on the second middle frame module 50 can prevent the door row assembly 21 from jumping during the engagement process between the rack 22 at the bottom of the door row assembly 21 and the second gear 92, thereby ensuring the precise engagement between the rack 22 at the bottom of the door row assembly 21 and the second gear 92.

[0132] like Fig.12 and Fig.13 As shown, in some embodiments, the pressure wheel mechanism 42 also includes a pressure wheel 420, a first side plate 421, a second side plate 422 and a pressure wheel shaft 423. The first side plate 421 and the second side plate 422 are arranged opposite to each other and are fixedly connected to the frame 41 respectively. The pressure wheel shaft 423 is passed between the first side plate 421 and the second side plate 422. The pressure wheel 420 is rotatably installed on the pressure wheel shaft 423 and is located between the first side plate 421 and the second side plate 422. During the process of meshing operation between the rack 22 at the bottom of the door row assembly 21 and the first gear 82, the pressure wheel 420 can be against the top surface of the door row assembly 21.

[0133] The two ends of the pressure wheel shaft 423 are respectively fixed to the first side plate 421 and the second side plate 422, and the pressure wheel 420 is sleeved on the pressure wheel shaft 423. After the door row module 20 is subjected to the upward force of the first gear 82 or the second gear 92, the pressure wheel 420 rolls in contact with the top surface of the door row assembly 21, which is beneficial to reduce the friction resistance and wear between the pressure wheel 420 and the door row module 20, and ensure that the rack 22 can smoothly enter the first rack 22 or the second rack 22, thereby reducing the noise and energy consumption during the operation of the door row module 20, and preventing the door row module 20 from getting stuck during operation.

[0134] In some embodiments, the pressing wheel mechanism 42 also includes a pressing wheel sleeve 424, and there are two pressing wheel sleeves 424, one of which is located between the first side plate 421 and the pressing wheel 420, and the other pressing wheel sleeve 424 is located between the second side plate 422 and the pressing wheel 420. The pressing wheel sleeve 424 can provide support and axial limitation for the pressing wheel shaft 423 to avoid shaking and position displacement of the pressing wheel shaft 423.

[0135] Optionally, the pressure wheel mechanism 42 also includes a pressure wheel bearing, which is arranged between the pressure wheel 420 and the pressure wheel shaft 423. The pressure wheel bearing can reduce the friction between the pressure wheel shaft 423 and the pressure wheel 420 and provide stable support for the pressure wheel 420, thereby ensuring the smoothness of the pressure wheel 420 during rolling and avoiding shaking and deviation.

[0136] In some embodiments, the pressing wheel mechanism 42 further includes a shaft clamp 425. The pressing wheel shaft 423 includes a connected head and a rod portion. An annular groove 4230 is provided at one end of the rod portion away from the head. After the rod portion of the pressing wheel shaft 423 passes through the first side plate 421, the first shaft sleeve, the pressing wheel, and the second side plate 422, the shaft clamp 425 is snapped into the annular groove 4230 to complete the assembly of the pressing wheel shaft 423. It can be understood that in other embodiments, the pressing wheel shaft 423 can also be fixed by riveting, screws, etc.

[0137] In some embodiments, a plurality of pressing wheel mechanisms 42 can be provided along the length direction of the door row module 20, and a plurality of pressing wheel mechanisms 42 can be provided along the thickness direction of the door row module 20. For example Fig.14 In [the example], two pressing wheel mechanisms 42 are respectively provided along the length direction and the thickness direction of the door row module 20. By pressing the pressing wheels of the plurality of pressing wheel mechanisms 42 against the top surface of the door row assembly 21, it can be ensured that the entire door row module 20 receives uniform pressure during the sliding process, avoiding tilting or shaking caused by uneven local stress, thereby more effectively preventing the door row module 20 from jumping and jittering during the sliding process and reducing the noise during the operation of the door row module 20.

[0138] In some embodiments, the first middle frame module 40 further includes an adjusting plate 43. The adjusting plate 43 is adjustably installed on the frame 41, and the pressing wheel mechanism 42 is fixedly installed on the adjusting plate 43. Specifically, the first side plate 421 and the second side plate 422 of the pressing wheel mechanism 42 can be fixedly connected to the adjusting plate 43, thereby fixedly installing the pressing wheel mechanism 42 on the adjusting plate 43. There can be one or more adjusting plates 43. One or more pressing wheel mechanisms 42 can be installed on one adjusting plate 43. For example, Fig.14 In [the example], two adjusting plates 43 are configured, and two pressing wheel mechanisms 42 are provided on each adjusting plate 43.

[0139] Strip-shaped holes are provided on the adjusting plate 43, and through the strip-shaped holes, it is convenient to adjust the height of the adjusting plate 43, thereby realizing the height adjustment of the pressing wheel mechanism 42 and facilitating the installation and debugging of the pressing wheel mechanism 42.

[0140] As Fig.14 shown, in some embodiments, the frame 41 includes a first upright column 411, a second upright column 412, and a top beam 410. The first upright column 411 and the second upright column 412 are oppositely arranged, and the door row module 20 can pass between the first upright column 411 and the second upright column 412. Both ends of the top beam 410 are respectively connected to the first upright column 411 and the second upright column 412. The first upright column 411, the second upright column 412, and the top beam 410 enclose a substantially "冂" shape.

[0141] In some embodiments, the frame 41 also includes a bracket assembly 413, which is arranged on the top beam 410. The bracket assembly 413 includes two support plates 4131 parallel to each other, and two cross beams 4132 parallel to each other. The two support plates 4131 are respectively fixedly connected to the inner sides of the first column 411 and the second column 412, and the two ends of the two cross beams 4132 are respectively fixedly connected to the two support plates 4131, and the two adjustment plates 43 can be adjusted and installed on the two cross beams 4132.

[0142] In this embodiment, the bracket assembly 413 provides more installation positions, and multiple pressing wheel mechanisms 42 can be installed, so as to more effectively prevent the door row module 20 from jumping upward during operation. It can be understood that in other embodiments, the bracket assembly 413 can also be omitted, and the pressing wheel mechanism 42 can also be directly installed on the top beam 410.

[0143] like Fig.12 , Fig.15 and Fig.16 As shown, in some embodiments, the first middle frame module 40 and the second middle frame module 50 are respectively provided with a guide mechanism 44, the guide mechanism 44 includes a support frame 440 and two sets of guide wheel assemblies 441, the support frame 440 is fixedly connected to the frame 41 and is located above the door row module 20, and the support frame 440 is provided with an avoidance opening 4400 for the pressure wheel mechanism 42 to pass through, the two sets of guide wheel assemblies 441 are arranged opposite to each other and are located at the bottom of the support frame 440, and the door row module 20 is arranged between the two sets of guide wheel assemblies 441.

[0144] The support frame 440 can be fixedly connected to the frame 41 by welding, threaded connection, etc. Specifically, the support frame 440 can be fixedly installed on the crossbeam 4132 of the frame 41. Optionally, the support frame 440 includes a base plate 4401 and connecting plates 4402 arranged at both ends of the base plate 4401, wherein the connecting plates 4402 are fixedly connected to the frame 41, and two sets of guide wheel assemblies 441 are installed at the bottom of the base plate 4401. The two sets of guide wheel assemblies 441 are respectively located on opposite sides of the door row module 20 in the thickness direction. The two sets of guide wheel assemblies 441 have a supporting and limiting effect on the door row module 20, ensuring that the door row module 20 does not tilt or shake during the sliding process, and ensuring the stable operation of the door row module 20.

[0145] The avoidance opening 4400 is opened on the base plate 4401 and corresponds to the position of the pressure wheel mechanism 42. The pressure wheel mechanism 42 can pass through the avoidance opening 4400 and abut against the top surface of the door row module 20, so that there is no need to occupy additional installation space. The pressure wheel mechanism 42 and the guide mechanism 44 have good structural compactness, and the pressure wheel mechanism 42 and the guide mechanism 44 can work together without interfering with each other.

[0146] Optionally, the guide mechanism 44 may be provided in plurality, for example, Fig.14 In the figure, a guide mechanism 44 is respectively arranged on the two cross beams 4132, and the door row module 20 can be better supported and guided by the multiple guide mechanisms 44.

[0147] like Fig.16 As shown, in some embodiments, each set of guide wheel assemblies 441 includes a guide wheel shaft 4411 and a guide wheel 4410, the guide wheel shaft 4411 is disposed at the bottom of the base plate 4401 and fixedly matched with the base plate 4401, the guide wheel 4410 is rotatably mounted on the guide wheel shaft 4411, and the door row assembly 21 is located between the two guide wheels 4410. Optionally, a connecting hole 4403 is provided on the base plate 4401, and the end of the guide wheel shaft 4411 can pass through the connecting hole 4403 and then be fixedly matched with the base plate 4401 through a fastener 4414.

[0148] Optionally, the guide wheel assembly 441 also includes a support bearing 4412 and a support sleeve 4413, both of which are sleeved on the guide wheel shaft 4411, and the support bearing 4412 is arranged between the guide wheel shaft 4411 and the guide wheel 4410 to support the guide wheel 4410 and reduce the friction between the guide wheel 4410 and the guide wheel shaft 4411.

[0149] The above mainly introduces the specific structure of the first middle frame module 40 . It should be understood that the specific structure of the second middle frame module 50 may be the same as that of the first middle frame module 40 , and will not be repeated here.

[0150] See also Figures 17 to 20 , and refer back to Fig. 9 In some embodiments, the door row module 20 further includes a first position limiting guide mechanism 23 and a second position limiting guide mechanism 25, the first position limiting guide mechanism 23 is arranged at one end of the door row assembly 21 facing the front frame module 30, and the second position limiting guide mechanism 25 is arranged at one end of the door row assembly 21 away from the front frame module 30;

[0151] The first position limiting guide mechanism 23 includes a first guide bracket 230 and a first guide block 231 and a position limiting wheel 232 disposed on the first guide bracket 230 . The second position limiting guide mechanism 25 includes a second guide bracket 250 and a second guide block 251 disposed on the second guide bracket 250 .

[0152] The front frame module 30 includes a frame body 31 and a limiting member 32 disposed on the frame body 31. The limiting member 32 includes two limiting arms 320 disposed opposite to each other, and a limiting groove 300 is formed between the two limiting arms 320.

[0153] The limiting wheel 232 can be engaged with the limiting groove 300, the first guide block 231 can be guided and matched with the two groups of guide wheel assemblies 441 on the first middle frame module 40, and the second guide block 251 can be guided and matched with the two groups of guide wheel assemblies 441 on the second middle frame module 50.

[0154] The limiting wheel 232 is disposed on one end of the first guide bracket 230 facing the front frame module 30 and is engaged with the limiting groove on the front frame module 30 . The first guide block 231 is disposed on the first guide bracket 230 and is engaged with the first middle frame module 40 .

[0155] like Fig.17 As shown, the first position limiting guide mechanism 23 is disposed at one end of the upper beam 211 facing the front frame module 30, and is fixedly connected to the upper beam 211 of the door row assembly 21 through the first guide bracket 230, so that the first position limiting guide mechanism 23 is installed on the door row assembly 21. Optionally, the first guide bracket 230 can be fixedly installed on the upper beam 211 by welding, threading, etc.

[0156] The first guide block 231 can be fixedly mounted on the first guide bracket 230 by means of snap connection, thread connection, etc. The first guide block 231 corresponds to the position of the guide wheel 4410 on the first middle frame module 40. When the door row module 20 moves toward the front frame module 30 and passes through the first middle frame module 40 and the second middle frame module 50, the first guide block 231 can cooperate with the guide wheel 4410 on the first middle frame module 40 to ensure that the door row module 20 enters the first middle frame module 40 smoothly and stably. Optionally, the end of the first guide block 231 away from the door row assembly 21 is an arc-shaped structure to reduce the friction and jamming when the first guide block 231 contacts the guide wheel 4410, so that the door row module 20 enters the first middle frame module 40 more smoothly.

[0157] The limiting wheel 232 is installed at one end of the first guide bracket 230 facing the front frame module 30 and corresponds to the position of the limiting groove 300, so as to facilitate the clamping fit between the limiting wheel 232 and the limiting groove 300. Optionally, a fixed shaft 233 is provided at one end of the first guide bracket 230 facing the front frame module 30, and the limiting wheel 232 is sleeved on the fixed shaft 233 and fixed by a snap ring 234.

[0158] During the closing process of the door row module 20, the door row module 20 gradually slides toward the front frame module 30, so that the distance between the limiting wheel 232 and the limiting groove 300 gradually decreases, until the limiting wheel 232 is inserted into the limiting groove 300, and the closing action of the door row module 20 is completed. The limiting engagement between the limiting wheel 232 and the limiting groove 300 makes the door row module 20 more stable after closing, and enhances the wind resistance and anti-collision capabilities of the door row module 20.

[0159] The second position limiting guide mechanism 25 is disposed at one end of the upper beam 211 away from the front frame module 30, and is fixedly connected to the upper beam 211 of the door row assembly 21 through the second guide bracket 250, so that the second position limiting guide mechanism 25 is installed on the door row assembly 21. Optionally, the second guide bracket 250 can be fixedly installed on the upper beam 211 by welding, threaded connection, etc.

[0160] The second guide block 251 can be fixedly installed on the second guide bracket 250 by means of snap connection, threaded connection, etc. The second guide block 251 corresponds to the position of the guide wheel 4410 on the second middle frame module 50. When the door row module 20 moves in the direction away from the front frame module 30 and passes through the second middle frame module 50, the second guide block 251 cooperates with the second middle frame module 50 to improve the smoothness of the door row module 20 entering the second middle frame module 50.

[0161] Optionally, the end of the second guide block 251 away from the door row assembly 21 is an arc-shaped structure to reduce friction and jamming when the second guide block 251 contacts the guide wheel 4410, so that the door row module 20 enters the second middle frame module 50 more smoothly.

[0162] In some embodiments, the diameter of the limiting wheel 232 is smaller than the distance between the two guide wheels 4410 relatively arranged on the first middle frame module 40, so that when the door row module 20 enters the first middle frame module 40, the limiting wheel 232 can pass through the gap between the two guide wheels 4410, and then the first guide block 231 can cooperate with the guide wheel 4410 to avoid interference between the limiting wheel 232 and the guide wheel 4410, so that the door row module 20 can enter the first middle frame module 40 more smoothly and accurately.

[0163] In some embodiments, the limiting arm 320 extends outward toward one end of the limiting wheel 232 and forms a guide arm 321. On the one hand, the guide arm 321 has a guiding function, which facilitates guiding the limiting wheel 232 to be smoothly inserted into the limiting groove 300, and avoids the limiting wheel 232 from being stuck during the engagement with the limiting groove 300. On the other hand, the distance between the two guide arms 321 is large, and the two guide arms 321 form a space for accommodating the first guide block 231. When the limiting wheel 232 is inserted into the limiting groove 300, the first guide block 231 is located between the two guide arms 321.
