Description

Technical Field

[0001] This invention relates to the field of technology, and in particular to a sliding door. Background Technology

[0002] Sliding doors are mainly used to control the entry and exit of people and vehicles. Due to their good safety and convenience, they are widely used in various factories, government agencies, schools, residential communities and other places.

[0003] However, when a sliding door is opened, it often forms only a single passageway, which can easily lead to mixed traffic of pedestrians and vehicles, causing mutual interference between the flow of people and vehicles, increasing the safety risks for pedestrians, and affecting traffic efficiency. Summary of the Invention

[0004] The present invention aims to provide a sliding door to solve the technical problem that existing sliding doors only have a single passage, which affects travel safety and passage efficiency.

[0005] The present invention addresses its technical problem by adopting the following technical solution: providing a sliding door, comprising:

[0006] guide;

[0007] A gate module, wherein the gate module is mounted on the guide rail;

[0008] The front frame module, the first middle frame module, and the second middle frame module are arranged sequentially along the length of the guide rail. A vehicle passage is formed between the front frame module and the first middle frame module, and a pedestrian passage is formed between the first middle frame module and the second middle frame module.

[0009] The gate module can slide along the guide rail to control the opening and closing of the vehicle passage and the pedestrian passage.

[0010] In some embodiments, a first side door for controlling the opening or closing of the pedestrian passage is also included, the first side door being disposed on one side of the guide rail and located between the first middle frame module and the second middle frame module;

[0011] When the gate module slides between the front frame module and the first middle frame module and the first side door opens, the vehicle passage closes and the pedestrian passage opens.

[0012] When the door module slides towards the front frame module to the first middle frame module and the first side door is closed, the vehicle passage opens and the pedestrian passage closes.

[0013] When the door module slides towards the front frame module to the second middle frame module and the first side door opens, both the vehicle passage and the pedestrian passage are opened.

[0014] When the gate module slides between the front frame module and the first middle frame module and the first side door is closed, both the vehicle passage and the pedestrian passage are closed.

[0015] In some embodiments, a second side door is also included, which is disposed on the side of the second mid-frame module opposite to the first mid-frame module;

[0016] The second middle frame module has a gap for the door module to slide through. When the second side door is opened, the door module is allowed to slide through the gap through the second middle frame module. When the second side door is closed, the gap is closed.

[0017] In some embodiments, the system further includes a first drive module and a second drive module, which are spaced apart along the length of the guide rail. The first drive module includes a first motor and a first gear, with the first motor being driven by the first gear.

[0018] The gate module includes a gate assembly and a rack disposed at the bottom of the gate assembly;

[0019] When the front end of the gate module is located at the front frame module, the gate module is driven to move away from the front frame module through the meshing transmission of the first gear and the rack, until the rack meshes with the second gear, and then the gate module continues to move away from the front frame module through the meshing transmission of the second gear and the rack, until the front end of the gate module moves to the first middle frame module, and the vehicle passage is opened;

[0020] When the front end of the gate module is located at the front frame module, the gate module is driven to move away from the front frame module through the meshing transmission of the first gear and the rack, until the rack meshes with the second gear. Then, the gate module is driven to continue moving away from the front frame module through the meshing transmission of the second gear and the rack, until the front end of the gate module moves to the second middle frame module, at which point both the vehicle passage and the pedestrian passage are opened.

[0021] When the front end of the gate module is located at the second middle frame module, the gate module is driven to move toward the front frame module through the meshing transmission of the second gear and the rack, until the rack meshes with the first gear. Then, the gate module is driven to continue moving toward the front frame module through the meshing transmission of the first gear and the rack, until the front end of the gate module moves to the front frame module, and the vehicle passage is closed.

[0022] In some embodiments, the center distance between the first gear and the second gear is equal to a multiple of the pitch of the rack.

[0023] In some embodiments, the first drive module includes a first base, and the first motor is mounted on the first base; the second drive module includes a second base, and the second motor is mounted on the second base.

[0024] The first base and the second base are spaced apart along the length of the guide rail;

[0025] At least one of the first base and the second base is provided with an adjustment hole, which is used to adjust the installation position of the first drive module or the second drive module so that the center distance is equal to a multiple of the tooth pitch.

[0026] In some embodiments, the first middle frame module includes a frame and a pressure roller mechanism mounted on the frame;

[0027] The pressure roller mechanism is located above the gate assembly and is used to limit the vertical displacement of the gate assembly.

[0028] In some embodiments, the pressure roller mechanism further includes a pressure roller, a first side plate, a second side plate, and a pressure roller shaft;

[0029] The first side plate and the second side plate are arranged opposite to each other and fixedly connected to the frame respectively. The pressure roller shaft passes through the first side plate and the second side plate. The pressure roller is rotatably mounted on the pressure roller shaft and located between the first side plate and the second side plate. The pressure roller can abut against the top surface of the door assembly.

[0030] In some embodiments, the first middle frame module and the second middle frame module are respectively provided with a guide mechanism, the guide mechanism including a support frame and two sets of guide wheel assemblies;

[0031] The support frame is fixedly connected to the frame and located above the gate module. The support frame is provided with a clearance for the pressure roller mechanism to pass through. Two sets of guide wheel assemblies are arranged opposite each other and located at the bottom of the support frame. The gate module is arranged between the two sets of guide wheel assemblies.

[0032] In some embodiments, the gate module further includes a first limiting guide mechanism and a second limiting guide mechanism, wherein the first limiting guide mechanism is disposed at one end of the gate assembly facing the front frame module, and the second limiting guide mechanism is disposed at one end of the gate assembly away from the front frame module;

[0033] The first limiting and guiding mechanism includes a first guide bracket, a first guide block and a first limiting wheel disposed on the first guide bracket; the second limiting and guiding mechanism includes a second guide bracket and a second guide block disposed on the second guide bracket;

They are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0065] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0066] Please see Figures 1 to 6 For ease of understanding and explanation, Figure 3 , Figure 4 and Figure 5The diagram shows the first position S1, the second position S2, and the third position S3. The first position S1 is a schematic diagram of the position when the end of the door module 20 facing the front frame module 30 (the front end of the door module 20) slides to the front frame module 30 (the position when the vehicle passage is closed). The second position S2 is a schematic diagram of the position when the end of the door module 20 facing the front frame module 30 slides to the first middle frame module 40. The third position S3 is a schematic diagram of the position when the end of the door module 20 facing the front frame module 30 slides to the second middle frame module 50.

[0067] This invention provides a sliding door 100, including a guide rail 10, a door panel module 20, a front frame module 30, a first middle frame module 40, and a second middle frame module 50. The door panel module 20 is mounted 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 sequentially along the length 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 panel 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, during the assembly of the sliding door 100, the guide rail 10 can be installed on the ground first, and then the front frame module 30, the first middle frame module 40, and the second middle frame module 50 can be fixed to the wall or ground, so that the front frame module 30, the first middle frame module 40, and the second middle frame module 50 are arranged sequentially along the length of the guide rail 10. Finally, the door panel module 20 is slidably installed on the guide rail 10, thus completing the assembly of the sliding door 100. After the sliding door 100 is assembled, the end of the door panel 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 collaboration and multi-mode operation, meeting the usage needs of different scenarios. Specifically:

[0069] like Figure 3 As shown, Figure 3 This is a schematic diagram of the state when the gate module 20 slides towards the front frame module 30 to the first position S1. At this time, the vehicle passage 101 is closed and the pedestrian passage 102 is open, allowing only pedestrians to pass, thus realizing the pedestrian passage 102 mode.

[0070] like Figure 4 As shown, Figure 4 This is a schematic diagram of the state when the gate module 20 slides to the second position S2 towards the front frame module 30. At this time, the vehicle passage 101 is in the open state and the pedestrian passage 102 is in the closed state, allowing only vehicles to pass, thus realizing the vehicle passage 101 mode.

[0071] like Figure 5 As shown, Figure 5 This is a schematic diagram of the state when the gate module 20 slides to the third position S3 towards the front frame module 30. At this time, both the pedestrian passage 102 and the vehicle passage 101 are open, and both pedestrians and vehicles can pass through, thus realizing the full passage mode (pedestrian and vehicle separation mode).

[0072] In summary, in this embodiment, by sliding the gate module 20 toward the front frame module 30 to different positions, pedestrian and vehicle traffic can be separated and isolated, improving traffic safety and efficiency. Furthermore, the sliding gate 100 has pedestrian access mode, vehicle access mode, and full access mode, allowing users to flexibly adjust the access mode according to actual application scenario requirements, achieving multi-channel collaboration and multi-mode operation to meet the usage needs of different scenarios.

[0073] Please see 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 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 the ground, and the door panel 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 module 20 slides towards the front frame module 30 to the first position S1 (at this time, the front end of the door module 20 is located at the front frame module 30, and the rear end of the door 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, thus realizing the pedestrian passage 102 mode.

[0075] like Figure 4 As shown, when the door module 20 slides towards the front frame module 30 to the second position S2 (at this time, the front end of the door 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, which realizes the vehicle passage mode.

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

[0077] like Figure 6As shown, when the door module 20 slides to the first position S1 towards the front frame module 30 and the first side door 60 is closed, both the vehicle passage 101 and the pedestrian passage 102 are closed, and pedestrians and vehicles are prohibited from passing through, thus realizing the fully closed mode (night mode).

[0078] Therefore, the door module 20 can cooperate with the first side door 60 to realize the pedestrian passage 102 mode, vehicle passage 101 mode, full passage mode and fully closed mode, to meet the usage needs 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 the side of the second middle frame module 50 opposite to the first middle frame module 40; the second middle frame module 50 is provided with a gap 501 for the door panel module 20 to slide through (see...). Figure 1 When the second side door 70 is opened, the door module 20 is allowed to slide through the gap 501 past the second middle frame module 50, and when the second side door 70 is closed, the gap 501 is sealed.

[0080] Specifically, when the door module 20 needs to slide from the first position S1 to the second position S2 or the third position S3, the door module 20 needs to pass through the second middle frame module 50. Therefore, the second side door 70 is configured to be in the open state, allowing the door 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 module 20 slides from the second position S2 or the third position S3 to the first position S1, a large gap 501 will be 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 module 20 is in the first position S1, so as to prevent people from entering or exiting through the gap 501 and improve 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, facilitating automated control of their opening and closing. For example, the first side door 60 and the second side door 70 can be configured as electric swing doors or electric retractable doors, etc.

[0083] In some embodiments, the sliding door 100 further includes a controller for controlling the movement of the door module 20 and the opening and closing of the first side door 60 and the second side door 70. Specifically, the controller can receive user input commands and control the movement of the door module 20 and the opening and closing of the first side door 60 and the second side door 70 accordingly, thereby enabling flexible switching of the sliding door 100 between different application modes. Optionally, the user can input corresponding commands via button switches, remote controls, mobile apps, etc.

[0084] When a user needs to enter the fully closed mode, the controller controls the door module 20 to slide towards the front frame module 30 until it reaches the front frame module 30, and controls the first side door 60 and the second side door 70 to close completely, thus entering the fully closed mode.

[0085] Optionally, the controller can first close the first side door 60 to prevent personnel from entering or exiting through the first side door 60 during the closing process of the door module 20, thus preventing potential safety hazards. After the first side door 60 is closed, the controller then sequentially closes the door module 20 and the second side door 70, thereby entering the fully closed mode.

[0086] When a user needs to enter the pedestrian passage mode, the controller controls the door module 20 to slide towards the front frame module 30 until it reaches the front frame module 30, and controls the second side door 70 to close to prevent safety hazards caused by people entering and exiting through the second side door 70. Finally, the controller controls the first side door 60 to open, and the user can enter the pedestrian passage mode.

[0087] When a user needs to enter the vehicle passage mode, the controller first controls the second side door 70 to open, and then controls the door module 20 to slide towards the front frame module 30 to the first middle frame module 40, thus entering the vehicle passage mode.

[0088] When a user needs to enter the full-passage mode, the controller first controls the second side door 70 to open. After the second side door 70 is in place, the controller then controls the door module 20 to slide towards the front frame module 30 to the second middle frame module 50. Finally, the controller controls the first side door 60 to open, and the user can enter the full-passage mode.

[0089] Please see Figures 7 to 11 In some embodiments, the sliding door 100 further includes a first drive module 80 and a second drive module 90, which are spaced apart along the length of the guide rail 10. The first drive module 80 includes a first motor 81 and a first gear 82, which are connected in a transmission manner. The second drive module 90 includes a second motor 91 and a second gear 92, which are connected in a transmission manner. The door panel module 20 includes a door panel assembly 21 and a rack 22 disposed at the bottom of the door panel assembly 21.

[0090] When the front end of the door module 20 is located at the front frame module 30, the first motor 81 starts and drives the door module 20 to move away from the front frame module 30 through the meshing of the first gear 82 and the rack 22. After the rack 22 meshes with the second gear 92, the second motor 91 starts and drives the door module 20 to continue moving away from the front frame module 30 through the meshing of the second gear 92 and the rack 22. This continues until the front end of the door module 20 moves to the first middle frame module 40, and the vehicle passage 101 is opened.

[0091] When the front end of the gate module 20 is located at the front frame module 30, the first motor 81 starts and drives the gate module 20 to move away from the front frame module 30 through the meshing of the first gear 82 and the rack 22. After the rack 22 meshes with the second gear 92, the second motor 91 starts and drives the gate module 20 to continue moving away from the front frame module 30 through the meshing of the second gear 92 and the rack 22. This continues until the front end of the gate module 20 moves to the second middle frame module 50, at which point both the vehicle passage 101 and the pedestrian passage 102 are opened.

[0092] When the front end of the gate module 20 is located at the second middle frame module 50, the second motor 91 starts and drives the gate module 20 to move toward the front frame module 30 through the meshing of the second gear 92 and the rack 22. After the rack 22 meshes with the first gear 82, the first motor 81 starts and drives the gate module 20 to continue moving toward the front frame module 30 through the meshing of the first gear 82 and the rack 22. The gate module 20 moves to the front frame module 30, and the vehicle passage 101 is closed.

[0093] In this way, the opening and closing of the vehicle passage 101 and the pedestrian passage 102 can be controlled by driving the gate module 20 on the guide rail 10 with dual motors.

[0094] Optionally, the first drive module 80 and the second drive module 90 can be configured on the same side of the guide rail 10. The first drive module 80 and the second drive module 90 can be mounted on the ground respectively. Alternatively, the first drive module 80 and the second drive module 90 can be mounted on the first mid-frame module 40 and the second mid-frame module 50 respectively. Optionally, the first drive module 80 can be located inside the first mid-frame module 40, and the second drive module 90 can be located inside the second mid-frame module 50, avoiding the first drive module 80 and the second drive module 90 occupying additional space and improving the overall structural compactness and neatness. Furthermore, the first drive module 80 can also be located on the front, rear, and outer sides of the first mid-frame module 40, and the second drive module 90 can also be located on the front, rear, and outer sides of the second mid-frame module 50.

[0095] like Figure 9 and Figure 10 As shown, the door panel assembly 21 may include an upper beam 211, a lower beam 212, and multiple door panels 210, wherein the multiple door panels 210 are disposed between the upper beam 211 and the lower beam 212. A rack 22 may be installed at the bottom of the lower beam 212, the rack 22 being arranged along the length direction of the bottom of the lower beam 212 and parallel to the length direction of the guide rail 10. A first gear 82 and a second gear 92 are respectively connected to a first motor 81 and a second motor 91 and are disposed at the bottom of the door panel assembly 21 to facilitate meshing between the first gear 82 and the second gear 92 and the rack 22. The first motor 81 and the second motor 91 drive the first gear 82 and the second gear 92 to rotate, thereby driving the rack 22 to move along the length direction of the guide rail 10, causing the door panel module 20 to slide along the guide rail 10.

[0096] In some embodiments, the first motor 81 and the second motor 91 are geared motors. Geared motors do not self-lock, so 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, thereby realizing the door module 20 to open and close the door, ensuring that the door module 20 can be opened in case of an accident, and ensuring the safety of the sliding door 100.

[0097] In some embodiments, both the first motor 81 and the second motor 91 are communicatively connected to the controller. Specifically, the controller can communicate with the first motor 81 and the second motor 91 wirelessly or via wired means. The controller can control the operation of the first motor 81 and the second motor 91, thereby controlling the opening and closing action of the door module 20.

[0098] The controller can receive user input of vehicle passage instructions, vehicle and pedestrian passage instructions, and vehicle restriction instructions. Optionally, users can input the corresponding instructions via remote control, button switch, mobile 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 both the vehicle passage 101 and the pedestrian passage 102 to open; and when the controller receives a vehicle restriction instruction, it can control the vehicle passage 101 to close.

[0100] When the gate module 20 is in position S1, if the controller receives a vehicle passage command, the controller performs the following steps:

[0101] A1. The controller controls the first motor 81 to rotate according to the vehicle passage command, while the second motor 91 does not rotate. It also 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 assembly 21 to move away from the front frame module 30, so that the rack 22 meshes with the second gear 92.

[0102] Optionally, the controller can limit the power supply to the second motor 91 by limiting the current flowing into the second motor 91 or by directly controlling the power outage of the second motor 91. Because the power supply to the second motor 91 is limited, the current flowing into the second motor 91 is smaller, and the electromagnetic force generated by the second motor 91 is smaller, allowing the second gear 92 at the output end of the second motor 91 to rotate freely, i.e., the second gear 92 can rotate under the push of the rack 22.

[0103] As the first motor 81 drives the first gear 82 and moves the rack 22 and gate assembly 21, the rack 22 gradually approaches and contacts the second gear 92. As the rack 22 continues to move, it pushes the second gear 92 to rotate, so that the rack 22 can smoothly and easily engage with the second gear 92, thereby reducing the jitter, skipping, and jamming when the rack 22 enters the second gear 92.

[0104] A2. After the rack 22 meshes 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 can limit the power supply to the first motor 81 by limiting the current flowing into the first motor 81 or by directly controlling the power to the first motor 81 to be cut off. At this 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 gate assembly 21 to continue moving away from the front frame module 30 until the front end of the gate 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. As the second motor 91 drives the second gear 92 to rotate and drives the rack 22 and the gate assembly 21 to continue moving, the rack 22 meshes with the first gear 82 and pulls the first gear 82 to rotate until the rack 22 and the first gear 82 separate. After the rack 22 and the first gear 82 separate, the second gear 92 will continue to drive the rack 22 and the gate assembly 21 to move until the front end of the gate module 20 moves to the first middle frame module 40, and the vehicle passage 101 opens.

[0107] When the gate module 20 is in position S1, if the controller receives a vehicle / pedestrian passage command, the controller executes the following steps:

[0108] B1. The controller controls the first motor 81 to rotate according to the vehicle and pedestrian passage instructions, while the second motor 91 does not rotate. It also 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 assembly 21 to move away from the front frame module 30, so that the rack 22 meshes with the second gear 92.

[0109] B2. After the rack 22 meshes 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 can limit the power supply to the first motor 81 by limiting the current flowing into the first motor 81 or by directly controlling the power to the first motor 81 to be cut off. At this 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 gate assembly 21 to continue moving away from the front frame module 30 until the front end of the gate 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 gate module is in position S3, if the controller receives a vehicle restriction command, the controller will perform the following steps:

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

[0113] C2. After the rack 22 meshes 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 can limit the power supply to the second motor 91 by limiting the current flowing into the second motor 91, or by directly controlling the power to the first motor 81 to be cut off. At this 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 gate assembly 21 to continue moving towards the front frame module 30 until the front end of the gate module 20 moves to the front frame module 30, and the vehicle passage is closed.

[0115] Through the above control method, during the process of the controller controlling the movement of the gate module 20, when the first motor 81 drives the gate assembly 21 to move, the second motor 91 stops running, and when the second motor 91 drives the gate assembly 21 to move, the first motor 81 stops running, ensuring that only one motor drives the gate module 20 to move at all times, avoiding phenomena such as gear skipping, shaking, jamming, and abnormal noise caused by speed deviation between the two motors, and ensuring the smooth operation of the gate module 20.

[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. For example... 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 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 integer multiple of the tooth pitch P, it can be ensured that during the simultaneous operation of the first drive module 80 and the second drive module 90 on the gate module 20, the rack 22 can precisely mesh with both the first gear 82 and the second gear 92. Thus, during the sliding process of the gate module 20, the rack 22 can smoothly transition from a state of meshing only with the first gear 82 or the second gear 92 to a state of precise meshing with both the first gear 82 and the second gear 92 simultaneously, avoiding tooth skipping, misalignment, and jamming during transmission, and ensuring smoothness, reliability, and low noise during transmission.

[0118] like Figure 10 and Figure 11 As shown, in some embodiments, the first drive module 80 further includes a first base 83, and the first motor 81 is mounted on the first base 83. The second drive module 90 includes a second base 93, and the second motor 91 is mounted on the second base 93. The first base 83 and the second base 93 are spaced apart along the length of the guide rail 10. At least one of the first base 83 and the second base 93 is provided with an adjustment hole 830. 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 jamming during the sliding of the gate module 20 and reducing noise during the transmission process.

[0119] The first base 83 and the second base 93 can have the same structure, both being roughly plate-shaped. The adjustment hole 830 can be a strip-shaped hole, with its length parallel to the length of the guide rail 10, to facilitate adjustment of the distance between the first drive module 80 and the second drive module 90. The first base 83 and the second base 93 can 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 fastener used to fix the first base 83, and then the installation position of the first base 83 can be finely adjusted 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 drive module 80 further includes a first housing 84, which is located in the middle of the first base 83. The adjustment hole 830 is opened at the periphery of the first base 83 to avoid the adjustment hole 830 being blocked by the first housing 84 and to improve the convenience of adjustment.

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

[0123] Optionally, the first chassis 84 includes a chassis 840 and a door 841 covering one side of the chassis 840. The door 841 is detachably installed on the chassis 840 for easy inspection and maintenance. The door 841 has a notch 8410, through which the output shaft of the first motor 81 can pass and be connected to the first gear 82 on the outside of the first chassis 84.

[0124] The second drive module 90 also includes a second housing 94, and the second motor 91 is installed in the second housing 94. The structure of the second housing 94 and the first housing 84 can be the same, which will not be described in detail here.

[0125] Optionally, the first drive module 80 also includes a motor mount 85, which is fixedly installed in the first housing 84. The first motor 81 is installed on the motor mount 85, and the motor mount 85 provides fixation and support for the first motor 81.

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

[0127] Optionally, the first drive module 80 also includes an electronic control board 89, which is electrically connected to the controller. The electronic control board 89 can receive control signals from the controller to control the first motor 81 to stop, accelerate or decelerate, and limit the power supply to the first motor 81.

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

[0129] Please see Figures 12 to 16 In some embodiments, the first middle frame module 40 includes a frame 41 and a pressure roller mechanism 42. The pressure roller mechanism 42 is mounted on the frame 41 and is located above the gate assembly 21 and is used to limit the vertical displacement of the gate assembly 21. During the process of the bottom rack 22 of the gate assembly 21 moving towards the first gear 82 and meshing with the first gear 82, the pressure roller mechanism 42 can abut against the top surface of the gate assembly 21, that is, the pressure roller 420 abuts against the top surface of the upper beam 211 to limit the vertical jump of the gate assembly 21.

[0130] During the operation of the gate assembly 21 driven by the second drive module 90, when the rack 22 at the bottom of the gate assembly 21 gradually approaches and meshes with the first gear 82, the gate assembly 20 will be subjected to an upward force from the first gear 82 because the first gear 82 is located at the bottom of the gate assembly 20. To prevent the gate assembly 20 from jumping, skipping teeth, and shaking due to the force from the first gear 82, this embodiment provides a pressure roller on the frame 41. During the operation of the rack 22 at the bottom of the gate assembly 21 meshing with the first gear 82, the pressure roller 420 of the pressure roller mechanism 42 will abut against the top surface of the gate assembly 21, thereby restricting the upward movement of the gate assembly 21, preventing jumping, skipping teeth and shaking during the operation of the gate assembly 21, ensuring that the rack 22 at the bottom of the gate assembly 21 is precisely meshed with the first rack 22 under the pressure of the pressure roller 420, and ensuring the stability and reliability of the gate module 20 during the sliding process along the guide rail 10.

[0131] It is understandable that the second middle frame module 50 also has the aforementioned pressure roller mechanism 42. The pressure roller mechanism 42 on the second middle frame module 50 can prevent the door panel assembly 21 from jumping during the meshing of the rack 22 at the bottom of the door panel assembly 21 with the second gear 92, thus ensuring the precise meshing of the rack 22 at the bottom of the door panel assembly 21 with the second gear 92.

[0132] like Figure 12 and Figure 13 As shown, in some embodiments, the pressure roller mechanism 42 further includes a pressure roller 420, a first side plate 421, a second side plate 422, and a pressure roller 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 roller shaft 423 passes through the first side plate 421 and the second side plate 422. The pressure roller 420 is rotatably mounted on the pressure roller shaft 423 and located between the first side plate 421 and the second side plate 422. During the operation of the rack 22 at the bottom of the door assembly 21 meshing with the first gear 82, the pressure roller 420 can abut against the top surface of the door assembly 21.

[0133] The two ends of the pressure roller shaft 423 are fixed to the first side plate 421 and the second side plate 422 respectively. The pressure roller 420 is sleeved on the pressure roller shaft 423. After the gate module 20 is subjected to the upward force of the first gear 82 or the second gear 92, the pressure roller 420 rolls into contact with the top surface of the gate assembly 21. This helps to reduce the frictional resistance and wear between the pressure roller 420 and the gate module 20, ensures that the rack 22 can smoothly enter the first rack 22 or the second rack 22, reduces the noise and energy consumption during the operation of the gate module 20, and prevents the gate module 20 from jamming during operation.

[0134] In some embodiments, the pressure roller mechanism 42 further includes a pressure roller bushing 424. There are two pressure roller bushings 424, one of which is located between the first side plate 421 and the pressure roller 420, and the other is located between the second side plate 422 and the pressure roller 420. The pressure roller bushings 424 can provide support and axial limit for the pressure roller shaft 423, thereby preventing the pressure roller shaft 423 from shaking and shifting position.

[0135] Optionally, the pressure roller mechanism 42 also includes a pressure roller bearing, which is disposed between the pressure roller 420 and the pressure roller shaft 423. The pressure roller bearing can reduce the friction between the pressure roller shaft 423 and the pressure roller 420 and provide stable support for the pressure roller 420, ensuring the smoothness of the pressure roller 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 means of 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 Figure 14 In, two pressing wheel mechanisms 42 are respectively provided along the length direction and the thickness direction of the door row module 20. By the pressing wheels of the plurality of pressing wheel mechanisms 42 abutting 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 inclination or shaking caused by uneven local stress, thereby more effectively preventing the jumping and jitter of the door row module 20 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 mounted on the frame 41. The pressing wheel mechanism 42 is fixedly mounted 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, so as to fixedly mount 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 mounted on one adjusting plate 43. For example, Figure 14 In, 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. Through the strip-shaped holes, it is convenient to adjust the height of the adjusting plate 43, so as to realize the height adjustment of the pressing wheel mechanism 42 and facilitate the installation and debugging of the pressing wheel mechanism 42.

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

[0141] In some embodiments, the frame 41 further includes a support assembly 413, which is disposed on the top beam 410. The support assembly 413 includes two parallel support plates 4131 and two parallel crossbeams 4132. The two support plates 4131 are fixedly connected to the inner sides of the first column 411 and the second column 412, respectively. The two ends of the two crossbeams 4132 are fixedly connected to the two support plates 4131, respectively. Two adjusting plates 43 are adjustablely installed on the two crossbeams 4132.

[0142] In this embodiment, the bracket assembly 413 provides more installation positions, allowing for the installation of multiple pressure roller mechanisms 42, thereby more effectively preventing the gate module 20 from jumping upwards during operation. It is understood that in other embodiments, the bracket assembly 413 may be omitted, in which case the pressure roller mechanism 42 can be directly installed on the top beam 410.

[0143] like Figure 12 , Figure 15 and Figure 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 panel module 20. The support frame 440 is provided with a clearance 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. The door panel module 20 is disposed 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, or other methods. 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 disposed at both ends of the base plate 4401. 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 located on opposite sides in the thickness direction of the door module 20. The two sets of guide wheel assemblies 441 provide support and limit the door module 20, ensuring that the door module 20 does not tilt or shake during sliding, thus ensuring the stable operation of the door module 20.

[0145] The clearance opening 4400 is formed on the substrate 4401 and corresponds to the position of the pressure roller mechanism 42. The pressure roller mechanism 42 can pass through the clearance opening 4400 and abut against the top surface of the door module 20, so as not to occupy additional installation space. The pressure roller mechanism 42 and the guide mechanism 44 have a good structural compactness, and the pressure roller mechanism 42 and the guide mechanism 44 can work together without interfering with each other.

[0146] Optionally, multiple guide mechanisms 44 may be provided, for example, Figure 14 In the middle, a guide mechanism 44 is set on each of the two crossbeams 4132. Through multiple guide mechanisms 44, the gate module 20 can play a better supporting and guiding role.

[0147] like Figure 16 As shown, in some embodiments, each guide wheel assembly 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 engaged with the base plate 4401. The guide wheel 4410 is rotatably mounted on the guide wheel shaft 4411. The gate assembly 21 is located between two guide wheels 4410. Optionally, a connection hole 4403 is provided on the base plate 4401, and the end of the guide wheel shaft 4411 can pass through the connection hole 4403 and be fixedly engaged with the base plate 4401 by a fastener 4414.

[0148] Optionally, the guide wheel assembly 441 further includes a support bearing 4412 and a support bushing 4413. The support bearing 4412 and the support bushing 4413 are both sleeved on the guide wheel shaft 4411. The support bearing 4412 is disposed 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 mid-frame module 40. It should be understood that the specific structure of the second mid-frame module 50 can be the same as that of the first mid-frame module 40, and will not be repeated here.

[0150] Please see Figures 17 to 20 And refer to Figure 9 In some embodiments, the gate module 20 further includes a first limiting guide mechanism 23 and a second limiting guide mechanism 25. The first limiting guide mechanism 23 is disposed at one end of the gate assembly 21 facing the front frame module 30, and the second limiting guide mechanism 25 is disposed at one end of the gate assembly 21 away from the front frame module 30.

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

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

[0153] The limiting wheel 232 can engage with the limiting groove 300, the first guide block 231 can guide and engage with the two sets of guide wheel assemblies 441 on the first middle frame module 40, and the second guide block 251 can guide and engage with the two sets 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 Figure 17 As shown, the first 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 assembly 21 through the first guide bracket 230, thereby installing the first limiting guide mechanism 23 on the door assembly 21. Optionally, the first guide bracket 230 can be fixedly installed on the upper beam 211 by welding, threaded connection or other methods.

[0156] The first guide block 231 can be fixedly installed on the first guide bracket 230 by means of snap-fit, threaded connection, etc. The position of the first guide block 231 corresponds to the guide wheel 4410 on the first middle frame module 40. When the door panel module 20 moves to 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 guide and cooperate with the guide wheel 4410 on the first middle frame module 40 to ensure that the door panel module 20 enters the first middle frame module 40 smoothly. Optionally, the end of the first guide block 231 facing away from the door panel assembly 21 has an arc-shaped structure to reduce friction and jamming when the first guide block 231 contacts the guide wheel 4410, so that the door panel module 20 enters the first middle frame module 40 more smoothly.

[0157] The limiting wheel 232 is installed on the 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 snap-fit ​​engagement between the limiting wheel 232 and the limiting groove 300. Optionally, a fixed shaft 233 is provided on the 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 retaining ring 234.

[0158] During the closing process of the door module 20, the door module 20 gradually slides towards the front frame module 30, causing the distance between the limiting wheel 232 and the limiting groove 300 to gradually decrease until the limiting wheel 232 engages with the limiting groove 300, thus completing the closing action of the door module 20. The engaging engagement between the limiting wheel 232 and the limiting groove 300 makes the door module 20 more stable after closing, enhancing its wind resistance and impact resistance.

[0159] The second limiting guide mechanism 25 is located at the 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 assembly 21 via the second guide bracket 250, thereby installing the second limiting guide mechanism 25 on the door assembly 21. Optionally, the second guide bracket 250 can be fixedly installed on the upper beam 211 by welding, threaded connection, or other methods.

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

[0161] Optionally, the end of the second guide block 251 facing away from the gate 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 gate 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 disposed opposite each other on the first middle frame module 40, so that when the gate 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 guide and cooperate with the guide wheel 4410 to avoid interference between the limiting wheel 232 and the guide wheel 4410, so that the gate module 20 can enter the first middle frame module 40 more smoothly and accurately.

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

[0164] In some embodiments, the guide rail 10 may be configured as a recessed rail, meaning that the guide rail 10 is embedded in the ground and flush with the ground, to improve the convenience and safety of passage. In other embodiments, the guide rail 10 may also be configured as a protruding rail, meaning that the guide rail 10 protrudes from the ground, to reduce the ease of installation and maintenance.

[0165] Please see Figure 21 And refer to Figure 9 In some embodiments, the gate module 20 further includes a wheel mechanism 24, which is disposed at the bottom of the lower beam 212 of the gate assembly 21. The wheel mechanism 24 includes a fixed base 241, a wheel bracket 242, and a wheel 243. The fixed base 241 is fixedly connected to the bottom of the lower beam 212, the wheel bracket 242 is rotatably mounted on the fixed base 241, and the wheel 243 is mounted on the wheel bracket 242 and rolls with the guide rail 10. The stable sliding of the gate module 20 is achieved by the rolling of the wheel 243 within the guide rail 10.

[0166] like Figure 21 As shown, the fixed base 241 can be installed at the bottom of the lower beam 212 via threaded connection, welding, or other methods. The wheel bracket 242 is rotatably installed at the bottom of the fixed base 241. The rotatable connection between the wheel bracket 242 and the fixed base 241 allows the wheel bracket 242 to drive the wheel 243 to rotate, enabling it to adapt to different guide rail heights and providing good height difference adjustment. In other words, when there is a height difference in the guide rails 10, the wheel bracket 242 can drive the wheel 243 to rotate to adjust the contact point between the wheel 243 and the guide rail 10, ensuring that the wheel 243 always maintains good contact with the guide rail 10.

[0167] Optionally, one or more wheels 243 may be configured on the wheel bracket 242. For example, in Figure 21 In the middle, the wheel bracket 242 is roughly "V" shaped. The middle part of the wheel bracket 242 is rotatably connected to the fixed base 241. A wheel 243 is provided at each end of the wheel bracket 242 to improve the support stability of the door module 20 and reduce the shaking and swaying of the door module 20.

[0168] In some embodiments, the wheel mechanism 24 further includes a first wheel shaft 244 and a second wheel shaft 245. The wheel bracket 242 is rotatably connected to the fixed base 241 via the first wheel shaft 244, and the wheel 243 is rotatably connected to the wheel bracket 242 via the second wheel shaft 245. Optionally, the wheel mechanism 24 further includes a wheel bearing 246, which is disposed between the second wheel shaft 245 and the wheel 243 to reduce friction between the second wheel shaft 245 and the wheel 243 and improve rotational smoothness.

[0169] Please see Figure 22 and Figure 23 In some embodiments, the first side door 60 includes a first doorpost 61, a second doorpost 62, and a door body 63. The first doorpost 61 and the second doorpost 62 can be fixed to the ground or a wall. The door body 63 is rotatably mounted on the first doorpost 61, and the rotation of the door body 63 can create an opening and closing action with the second doorpost 62. Optionally, the first doorpost 61 and the second doorpost 62 are hollow inside to facilitate the installation of other components of the first side door 60.

[0170] In some embodiments, the first side door 60 further includes a drive motor 64 and a linkage assembly 65. The linkage assembly 65 includes a straight arm 650 and a curved arm 651 rotatably connected. The drive motor 64 is fixedly installed inside the first door post 61, and the output shaft of the drive motor 64 protrudes from the top of the first door post 61. The end of the straight arm 650 away from the curved arm 651 is connected to the output shaft of the drive motor 64, and the end of the curved arm 651 away from the straight arm 650 is connected to the door body 63. The drive motor 64 can drive the linkage assembly 65 to rotate, thereby driving the door body 63 to rotate to form an opening and closing action.

[0171] In some embodiments, a first magnetic chuck 631 and a second magnetic chuck 632 are provided on opposite sides of the door 63. A third magnetic chuck 610 is provided on the first doorpost 61 to magnetically engage with the first magnetic chuck 631, and a fourth magnetic chuck 620 is provided on the second doorpost 62 to magnetically engage with the second magnetic chuck 632. When the door 63 is opened, the first magnetic chuck 631 on the door 63 and the third magnetic chuck 610 on the first doorpost 61 gradually approach each other until they are magnetically attracted, thus completing the opening of the door 63. When the door 63 is closed, the second magnetic chuck 632 on the door 63 and the fourth magnetic chuck 620 on the second doorpost 62 gradually approach each other until they are magnetically attracted, thus completing the closing of the door 63.

[0172] Optionally, one of the first magnetic attractor 631 and the third magnetic attractor 610 is a magnet, and the other is a ferromagnet, such as iron, nickel, cobalt and their alloys. Similarly, one of the second magnetic attractor 632 and the fourth magnetic attractor 620 is a magnet, and the other is a ferromagnet.

[0173] In some embodiments, the first side door 60 further includes a control module 66, which may include electronic components such as a control circuit board. The control module 66 may be installed on the first door post 61 and electrically connected to the drive motor 64. The control module 66 can control the start and stop of the drive motor 64, thereby controlling the opening and closing of the first side door 60.

[0174] The above mainly introduces the specific structure of the first side door 60. It should be understood that the specific structure of the second side door 70 can be the same as that of the first side door 60, and will not be repeated here.
