Description

TECHNICAL FIELD

[0001] The utility model relates to building technology field especially a kind of magnetic levitation structure and sliding door device. BACKGROUND

[0002] In prior art, the moving rail of magnetic levitation door body is bent due to long-term overload, which causes the door body unable to close or open. Meanwhile, the motor, power supply and other accessories in the fixed guide rail are installed in advance from the side port, which cannot be replaced from the installed rail, so that the sliding rail, door body and outer frame need to be disassembled during maintenance and replacement, which is complicated. Meanwhile, the magnetic levitation motor assembly on the market is combined with double motors, which is relatively long and complicated to replace. SUMMARY

[0003] Therefore, it is necessary to provide a magnetic levitation structure and sliding door device to solve the problems of long-term overload of the moving rail and inconvenience of disassembly and assembly of accessories.

[0004] A magnetic levitation structure, comprising: a magnetic levitation motor assembly; a moving rail assembly arranged opposite to the magnetic levitation motor assembly, which can realize reciprocating motion under the magnetic force of the magnetic levitation motor assembly; and a door assembly, a part of which is arranged opposite to the moving rail assembly, and the other part of which is in contact with the moving rail assembly, which can realize reciprocating motion under the driving of the moving rail assembly.

[0005] The above-mentioned magnetic levitation structure separates the door assembly and the moving rail assembly, which reduces the burden of the door body on the moving rail assembly. When the burden of the moving rail assembly is reduced, the pressure it receives is within a reasonable range, which avoids the bending deformation of the moving rail assembly due to long-term overload. The number of times of maintenance or replacement due to damage of the guide rail can be reduced. At the same time, the pressure between the overloaded slider and the guide rail can be reduced, which reduces the friction and prolongs the service life of the moving rail assembly. On the other hand, if the moving rail assembly is bent due to long-term overload, it will also affect the running accuracy of the door body. Once the guide rail is deformed, the door body will be stuck or deviated when running on the guide rail. After the burden is reduced by relative separation, the straightness and other accuracy requirements of the moving rail assembly can be guaranteed, so that the door body can open and close smoothly and accurately along the guide rail. The magnetic levitation motor assembly controls the moving rail assembly, and the guide rail assembly drives the door assembly, which reduces the influence of friction during the movement of the door body, so as to realize more convenient and smooth opening and closing action.

[0006] In one of the embodiments, the magnetic levitation motor assembly comprises two magnetic levitation motor fixed blocks and a magnetic levitation motor module. The two magnetic levitation motor fixed blocks are arranged at two ends of the magnetic levitation motor module and are arranged on the fixed guide rail. The magnetic levitation motor module comprises a shell, a linear motor and a controller. The linear motor is arranged in the shell, and the controller is electrically connected with the linear motor. The two magnetic levitation motor fixed blocks can provide stable basic support for the whole magnetic levitation structure and ensure the position accuracy of the magnetic levitation motor module during operation, preventing large deviation in the horizontal direction. The magnetic levitation motor fixed blocks arranged at the two ends of the magnetic levitation motor module can effectively limit the swing of the magnetic levitation motor module and limit the swing amplitude, ensuring the stability of the operation. The shell can provide a physical barrier for the linear motor and the controller, avoiding collision, impact and extrusion by external objects. At the same time, it can also prevent dust, debris, liquid and other foreign matters from entering. If these impurities enter the motor or the controller, it may cause short circuit, accelerated wear and other problems. The controller is electrically connected with the linear motor, and the controller sends electrical signals to the linear motor through the electrical connection, thereby controlling the moving speed of the moving rail assembly.

[0007] In one of the embodiments, the number of door belt assemblies is multiple, and the multiple door belt assemblies are arranged at two ends of the moving rail assembly. The evenly distributed load can make the structure in a more stable state, and the vertical pressure on the fixed guide rail can be more evenly distributed in the length direction. If the door belt assembly is located on one side of the moving rail assembly, the lateral force and torque will act on one side of the fixed guide rail, which is easy to cause the fixed guide rail to produce side bending or twisting deformation. Therefore, this structure helps to maintain the shape and structural integrity of the fixed guide rail, avoids material fatigue, deformation and other problems caused by excessive local pressure, thereby prolonging the service life of the sliding door device.

[0008] In one of the embodiments, the moving rail assembly comprises a moving rail and a plurality of sliding wheel assemblies, the moving rail is arranged opposite to the maglev motor assembly, the plurality of sliding wheel assemblies are arranged along the length direction of the moving rail and are arranged at two ends of the moving rail, and at least part of the plurality of sliding wheel assemblies are in contact with the door body. By arranging the moving rail below the maglev motor assembly, the interaction between the magnetic poles provides the moving rail with magnetic levitation force, and the maglev motor assembly enables the moving rail assembly to move along the fixed guide rail, so that the door body does not deviate from the track during opening and closing. By arranging the plurality of sliding wheel assemblies along the length direction of the moving rail and at two ends of the moving rail, the moving rail can move smoothly on the fixed guide rail, and the sliding wheel assemblies distributed at two ends can effectively prevent the moving rail from tilting during sliding. If there is only one sliding wheel assembly or the sliding wheel assemblies are concentrated at a certain position of the guide rail, the door body is easy to tilt or even derail when subjected to lateral force. The sliding wheel assemblies at two ends can keep the moving rail balanced in the vertical and horizontal directions, reduce shaking, and better ensure that the door body moves smoothly in the correct direction along the guide rail. This arrangement helps to prolong the service life of the moving rail and the sliding wheel assembly, because the load is evenly distributed, the pressure and wear of each component are relatively small, the sliding wheel assemblies at two ends can buffer impact force, reduce damage to the guide rail and the wheels themselves, and enable the entire system to operate more durably. By driving the door body through the sliding wheel assembly, the sliding wheel assembly can be moved when the moving rail moves, and then the door body can be moved through the sliding wheel assembly.

[0009] In one of the embodiments, the sliding wheel assembly comprises a sliding wheel, a sliding fixing block and a fastening bolt, the sliding fixing block is arranged on the moving rail, the number of the sliding wheels is multiple, the multiple sliding wheels are arranged on both sides of the sliding fixing block, and the fastening bolt is arranged through the sliding fixing block and the magnetic levitation motor assembly to connect the sliding fixing block and the magnetic levitation motor assembly. By arranging the sliding fixing block on the moving rail, arranging the multiple sliding wheels on both sides of the sliding fixing block, and connecting the sliding fixing block and the magnetic levitation motor assembly by the fastening bolt, a stable structure is formed, the relative displacement between the components can be effectively prevented, the magnetic levitation structure is not easily separated due to vibration or external force, the integrity of the magnetic levitation structure is ensured, and the normal operation of the door body is not affected. The multiple sliding wheels are arranged on both sides of the sliding fixing block, so that the stress is more uniform, the force received by the moving rail during movement can be evenly distributed to the sliding wheels on both sides, the local excessive stress is reduced, the stability of the whole structure is enhanced, the multiple sliding wheels can reduce the friction during movement, the moving rail can move more flexibly, the response speed and operation efficiency of the sliding door device can be improved, and the door body can be quickly and stably opened and closed. During the operation of the sliding door device, vibration and impact are inevitable, when the vibration or impact is transmitted to the magnetic levitation structure, part of the energy is first absorbed by the sliding fixing block and the sliding wheel, since the sliding wheel and the fixed guide rail are in rolling contact, they can consume the vibration energy through elastic deformation and rolling friction, so as to reduce the influence of vibration and impact on the magnetic levitation structure and the sliding door device.

[0010] In one of the embodiments, the door body assembly comprises a driven assembly and a transmission assembly, the driven assembly is arranged on the fixed guide rail and clamped between the multiple sliding wheel assemblies, and the transmission assembly is arranged on the driven assembly. By arranging the driven assembly on the fixed guide rail and clamping the driven assembly between the multiple sliding wheel assemblies, the weight of the door body can be avoided to fall on the moving rail, the burden of the moving rail can be reduced, the bending deformation of the moving rail can be effectively prevented, and the service life of the sliding door device can be prolonged. Since the driven assembly is clamped between the sliding wheel assemblies, the door body can be driven by the moving rail, the door body can move normally along the fixed track, the shaking and swinging of the driven assembly during movement can be reduced, the precise opening and closing of the door can be realized, and the movement stability of the whole sliding door device can be improved. By arranging the transmission assembly on the driven assembly, the door body and the driven assembly can be driven to move cooperatively by the transmission assembly as an intermediate of power transmission, so that the sliding door device can better maintain its functional integrity when facing external interference such as vibration and impact.

[0011] In one embodiment, the driven assembly includes a connecting assembly and a driven wheel assembly, the number of driven wheel assemblies is multiple, multiple driven wheel assemblies are arranged on the fixed guide rail, the connecting assembly is arranged on multiple driven wheel assemblies, and multiple driven wheel assemblies are arranged on both sides of the connecting assembly. By arranging multiple driven wheel assemblies on the fixed guide rail, precise guidance can be provided for the door body. This precise guidance ensures that the door body moves along a predetermined trajectory during opening and closing operations, avoiding random translation or rotation of the door body in the plane, which is crucial for maintaining the correct relative position relationship between the door body and the fixed guide rail. At the same time, multiple driven wheel assemblies are distributed on the fixed guide rail and work together to maintain the stability of the door body. Multiple driven wheel assemblies are in contact with the guide rail and can work together to resist minor collisions and other disturbances. On the other hand, the door body has a certain mass and generates a gravitational load. Multiple driven wheel assemblies arranged on the fixed guide rail can effectively disperse the gravitational load of the door body, preventing damage to the guide rail or the driven wheel assembly itself caused by excessive local pressure, and ensuring that the fixed guide rail can stably bear the weight of the door body for a long time. Multiple driven wheel assemblies are arranged on both sides of the connecting assembly. During the movement of the door body, the connecting assembly may be subjected to various complex forces. If the driven wheel assemblies are concentrated on one side, the connecting assembly is prone to distortion during force transmission due to uneven stress. The driven wheel assemblies arranged on both sides can make the force distribution on the connecting assembly more symmetrical, ensuring that the force is evenly transmitted to each driven wheel assembly through the connecting assembly, thereby preventing distortion of the connecting assembly and the entire door body structure, and ensuring the structural integrity of the door body.

[0012] In one embodiment, the connecting assembly includes a connecting block and a fixed shaft, the number of fixed shafts is multiple, multiple fixed shafts are arranged on both sides of the connecting block, and multiple fixed shafts are arranged on the driven wheel assembly. By arranging multiple fixed shafts on both sides of the connecting block and multiple fixed shafts on the driven wheel assembly, the door body load can be more evenly distributed. The weight of the door body is transmitted to the fixed shaft, which is then dispersed to each driven wheel assembly. This bilateral distribution method avoids concentrating the load on one side or one point, allowing each driven wheel assembly to bear relatively balanced pressure and preventing component damage caused by excessive local pressure. At the same time, multiple fixed shafts distributed on both sides can reduce the vibration and shaking of the door body during movement. When the door body moves, any slight imbalance or external disturbance can cause vibration. The bilateral fixed shafts and driven wheel assemblies can form a more stable structure that works together to absorb and disperse these vibration energies, making the door body movement more stable and avoiding the impact of shaking on the normal use and service life of the door body.

[0013] In one of the embodiments, the driven wheel assembly includes a driven fixed block and driven wheels, the number of driven wheels is multiple, multiple driven wheels are arranged on both sides of the driven fixed block, multiple driven wheels are arranged on the fixed guide rail, and the connecting assembly is arranged on the driven fixed block. By arranging multiple driven wheels on both sides of the driven fixed block, and then arranging multiple driven wheels on the fixed guide rail, and at the same time arranging the connecting assembly on the driven fixed block, on the one hand, multiple driven wheels are distributed on both sides of the driven fixed block and in contact with the fixed guide rail, and this layout can effectively balance the weight of the door body, and the gravity of the door body is transmitted to the driven wheels on both sides of the driven fixed block, avoiding the concentration of load in one place and reducing the risk of damage to a single driven wheel due to overload. On the other hand, when the door body is subjected to lateral force or torque, the driven wheels on both sides can cooperate to resist these forces, thereby maintaining the balance of the door body and preventing the door body from tilting or deviating from the fixed guide rail.

[0014] The second aspect of the present application discloses a sliding door device, which comprises: the magnetic suspension structure described above; a fixed guide rail, the magnetic suspension motor assembly and the door assembly are arranged on the fixed guide rail, the fixed guide rail is provided with an opening and a guide opening, the guide opening communicates with the opening, the opening and the guide opening are used for disassembling the magnetic suspension structure, the movable rail can pass through the guide opening, and the sliding wheel assembly can pass through the opening; a door body, the door body is arranged on the door assembly, and the door body is electrically connected with the fixed guide rail; a power supply assembly, the power supply assembly is arranged in the fixed guide rail, the power supply assembly can be turned over in the fixed guide rail and disassembled through the guide opening; a plurality of lower sealing strips, the plurality of lower sealing strips are arranged on the fixed guide rail.

[0015] The above sliding door device sets the magnetic suspension motor assembly and the door assembly on the fixed guide rail, and the fixed guide rail provides a fixed mounting position for the magnetic suspension motor assembly and the door assembly. The movement of the magnetic suspension motor assembly and the door assembly is based on the interaction with the fixed guide rail, and such a setting strictly limits their movement in the direction defined by the guide rail, avoiding arbitrary translation or rotation in the plane. For the opening and closing operation of the door body, this ensures that the door body can move along the predetermined trajectory, thereby ensuring the correct relative position relationship between the door body and the door frame or other surrounding structures. On the other hand, the door body has a certain mass and generates a gravitational load. The magnetic suspension motor assembly and the door assembly are arranged on the fixed guide rail, which can share the weight of the door body and ensure the structural safety of the moving rail assembly. The opening is arranged on the fixed guide rail to provide a direct operation space for the installation of the moving rail assembly and the motor and other accessories, which can more conveniently adjust the installation position, ensure smooth movement and accurate position of the door body on the guide rail, and also save maintenance time and workload. The door body is arranged on the door assembly, and the door assembly serves as a carrier of the door body, which is the key to realizing the opening and closing function of the door body. Through the connection with the door assembly, the door body can be driven and guided by the door assembly to complete the opening and closing action, and can also smoothly slide along the guide rail to achieve the purpose of controlling the entry and exit of personnel and objects. The power supply assembly is arranged in the fixed guide rail, and the power supply assembly can rotate in the fixed guide rail by using the gap between the power supply assembly and the fixed guide rail, and finally be taken out from the guide opening, which greatly improves the convenience of disassembling the sliding door device. The lower sealing strip is arranged on the fixed guide rail, which can provide physical protection for the guide rail and hide the internal structure and connection part of the guide rail, making the sliding door device look more neat and beautiful and improving its market competitiveness.

[0016] In one embodiment, the power supply assembly includes a plurality of fixed parts arranged on the fixed guide rail, and a power supply body arranged on the plurality of fixed parts. By arranging a plurality of fixed parts on the fixed guide rail, a clear mounting position is provided for the power supply body, avoiding poor connection or failure due to positional deviation. At the same time, the combined action of the plurality of fixed parts can more evenly distribute the weight and external force of the power supply body, reducing local stress concentration and thereby enhancing the stability of the power supply body on the fixed guide rail. Moreover, the plurality of fixed parts can effectively resist these external forces to ensure that the power supply body does not loosen or shift. When the power supply assembly needs to be disassembled and repaired, the fixed parts only need to be loosened, and then the power supply body can be rotated and turned over to be taken out for repair through the gap, saving maintenance time and workload.

[0017] In one of the embodiments, the lower sealing strip comprises a fixed long strip and a shielding long strip, the fixed long strip is arranged on the fixed guide rail, and the shielding long strip is arranged on the fixed long strip and opposite to the opening and the notch of the fixed guide rail. By arranging the fixed long strip on the fixed guide rail, a specific mounting position is provided for the shielding long strip, so that the shielding long strip can shield the opening and the notch of the fixed guide rail, and to a certain extent, prevent dust and other sundries from entering the inside of the guide rail. In addition, the opening and the notch of the fixed guide rail may have certain safety hazards, and people may accidentally touch the sharp edges and be injured. Therefore, the shielding long strip plays a certain protective role. Finally, the shielding long strip can make the fixed guide rail look more neat and beautiful, and improve the user experience.

[0039] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0041] The magnetic levitation structure and sliding door device of this utility model are described below with reference to the accompanying drawings.

[0042] Example 1

[0043] like Figures 1 to 7 As shown, this embodiment discloses a magnetic levitation structure, including: a magnetic levitation motor assembly 1; a moving rail assembly 2, which is disposed opposite to the magnetic levitation motor assembly 1, and the moving rail assembly can achieve reciprocating motion under the magnetic drive of the magnetic levitation motor assembly; and a door assembly 3, a part of which is disposed opposite to the moving rail assembly 2, and the other part of which is in contact with the moving rail assembly 2, and the door assembly 3 can achieve reciprocating motion under the drive of the moving rail assembly 2.

[0044] The application discloses a magnetic suspension structure, which is characterized in that the door assembly 3 is arranged in relative separation with the moving rail assembly 2, so that the burden of the moving rail assembly 2 caused by the door body weight is reduced, the pressure received by the moving rail assembly 2 is within a reasonable range after the burden is reduced, the moving rail assembly 2 is prevented from being bent and deformed due to long-term overload, and the number of times of maintenance or replacement due to damage of the guide rail can be reduced. Meanwhile, the pressure between the overload slider and the guide rail is reduced, the friction force is increased, the moving rail assembly 2 is prevented from being worn out, the relative separation arrangement reduces the friction force, and the service life of the moving rail assembly 2 is prolonged. On the other hand, if the moving rail assembly 2 is bent and deformed due to long-term overload, the running accuracy of the door body is affected, once the guide rail is deformed, the door body will be jammed or deviated when running on the guide rail, and after the burden is reduced by the relative separation arrangement, the straightness and other accuracy requirements of the moving rail assembly 2 are ensured, so that the door body can be smoothly and accurately opened and closed along the guide rail. The magnetic suspension motor assembly 1 is used for controlling the moving rail assembly 2, the guide rail drill assembly 2 is used for driving the door assembly 3, the influence of the friction force on the door body in the moving process is reduced, and more convenient and smooth opening and closing actions are realized.

[0045] As Figure 2 , Figure 3 , Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the magnetic levitation motor assembly 1 includes two magnetic levitation motor fixing blocks 11 and a magnetic levitation motor module 12. The two magnetic levitation motor fixing blocks 11 are respectively disposed at both ends of the magnetic levitation motor module 12. The two magnetic levitation motor fixing blocks 11 are mounted on the fixed guide rail 100. The magnetic levitation motor module 12 includes a housing 121, a linear motor 122, and a controller 123. The linear motor 122 is disposed inside the housing 121, and the controller 123 is electrically connected to the linear motor 122. By mounting the two magnetic levitation motor fixing blocks 11 on the fixed guide rail 100 and simultaneously mounting the magnetic levitation motor fixing blocks 11 at both ends of the magnetic levitation motor module 12, the two magnetic levitation motor fixing blocks 11 can first provide a stable foundation support for the entire magnetic levitation structure, and also ensure the positional accuracy of the magnetic levitation motor module 12 during operation, preventing it from having a large deviation in the horizontal direction. Secondly, magnetic levitation motor fixing blocks 11 are set at both ends of the magnetic levitation motor module 12, which can effectively limit the swing of the magnetic levitation motor module 12 and limit the sway amplitude of the magnetic levitation motor module 12, ensuring its operational stability. By placing the linear motor 122 and controller 123 inside the housing 121, the housing 121 can provide a physical barrier for the linear motor 122 and controller 123, preventing them from being hit, impacted, or squeezed by external objects. At the same time, it can also prevent foreign objects such as dust, debris, and liquids from entering. If these impurities enter the motor or controller, they may cause problems such as short circuits and accelerated wear. Meanwhile, the controller 123 is electrically connected to the linear motor 122, and the controller 123 sends electrical signals to the linear motor 122 through the electrical connection, thereby controlling the moving speed of the moving rail assembly 2.

[0046] like Figure 1 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of door assemblies 3 is multiple, and the multiple door assemblies 3 are distributed at both ends of the moving rail assembly 2. By distributing the multiple door assemblies 3 at both ends of the moving rail assembly 2, the uniformly distributed load can make the structure more stable, and the vertical pressure on the fixed guide rail 100 can be more evenly distributed along its length. If the door assembly 3 is only located on one side of the moving rail assembly 2, these lateral forces and torques will be concentrated on one side of the fixed guide rail 100, which can easily cause the fixed guide rail 100 to bend or twist. Therefore, this structure helps to maintain the shape and structural integrity of the fixed guide rail 100, avoid problems such as material fatigue and deformation caused by excessive local pressure, and thus extend the service life of the sliding door device.

[0047] like Figure 1 , Figure 4 and Figure 11As shown, in addition to the features of the above embodiments, the present embodiment is further limited in that: the moving rail assembly 2 comprises a moving rail 21 and a plurality of sliding wheel assemblies 22, the moving rail 21 is arranged opposite to the magnetic levitation motor assembly 1, the plurality of sliding wheel assemblies 22 are arranged along the length direction of the moving rail 21 and are arranged at both ends of the moving rail 21, and at least part of the plurality of sliding wheel assemblies 22 are in contact with the door body assembly 3. By arranging the moving rail 21 below the magnetic levitation motor assembly 1, the magnetic levitation force is provided for the moving rail 21 by the interaction between the magnetic poles, and the magnetic levitation motor assembly 1 moves the moving rail assembly 2 along the direction of the fixed guide rail 100, so that the door body does not deviate from the track during opening and closing. Arranging the plurality of sliding wheel assemblies 22 along the length direction of the moving rail 21 and at both ends of the moving rail 21 enables the moving rail 21 to move smoothly on the fixed guide rail 100, and the sliding wheel assemblies 22 distributed at both ends can effectively prevent the moving rail 21 from tilting during sliding. If there is only one sliding wheel assembly 22 or the sliding wheel assemblies 22 are concentrated at a certain place of the guide rail, when the door body is subjected to a lateral force, it is easy to tilt or even derail. The sliding wheel assemblies 22 at both ends can keep the moving rail 21 balanced in the vertical and horizontal directions, reduce shaking, and better ensure that the door body moves smoothly in the correct direction along the guide rail. This arrangement helps to prolong the service life of the moving rail 21 and the sliding wheel assemblies 22, as the load is evenly distributed, the pressure and wear of each component are relatively small, the sliding wheel assemblies 22 at both ends can buffer the impact force, reduce damage to the guide rail and the wheels themselves, and enable the entire system to operate more durably. By driving the door body assembly 3 through the sliding wheel assemblies 22, the sliding wheel assemblies 22 can be moved when the moving rail 21 moves, and the door body assembly 3 can be moved through the sliding wheel assemblies 22.

[0048] As Figure 1 , Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, the present embodiment is further defined as: the sliding wheel assembly 22 comprises a sliding wheel 221, a sliding fixed block 222 and a fastening bolt 223, the sliding fixed block 222 is arranged on the moving rail 21, the number of the sliding wheels 221 is multiple, the multiple sliding wheels 221 are arranged on both sides of the sliding fixed block 222, and the fastening bolt 223 is arranged through the sliding fixed block 222 and the magnetic levitation motor assembly 1 to connect the sliding fixed block 222 and the magnetic levitation motor assembly 1. By arranging the sliding fixed block 222 on the moving rail 21, arranging the multiple sliding wheels 221 on both sides of the sliding fixed block 222, and connecting the sliding fixed block 222 and the magnetic levitation motor assembly 1 by the fastening bolt 223, a stable structure is formed. This connection method can effectively prevent the relative displacement between the components, and will not easily separate due to vibration or external force, thereby ensuring the integrity of the magnetic levitation structure and avoiding loosening to affect the normal operation of the door body. The multiple sliding wheels 221 arranged on both sides of the sliding fixed block 222 can make the stress more uniform, and the force received by the moving rail 21 when moving can be evenly distributed to the sliding wheels 221 on both sides, thereby reducing the case of excessive local pressure and enhancing the stability of the entire structure. At the same time, the arrangement of multiple sliding wheels 221 can reduce the frictional force in the moving process, so that the moving rail 21 can move more flexibly, and the response speed and operation efficiency of the sliding door device can be improved, so that the door body can be quickly and smoothly opened and closed. In the operation process of the sliding door device, vibration and impact will inevitably occur, and when the vibration or impact is transmitted to the magnetic levitation structure, a part of the energy will be first absorbed by the sliding fixed block 222 and the sliding wheel 221. Since the sliding wheel 221 and the fixed guide rail 100 are in rolling contact, they can consume vibration energy through elastic deformation and rolling friction, thereby reducing the influence of vibration and impact on the magnetic levitation structure and the sliding door device.

[0049] As Figure 1 , Figure 6 and Figure 11As shown, in addition to the features of the above embodiments, the present embodiment is further defined as: the door assembly 3 comprises a driven assembly 31 and a transmission assembly 32, the driven assembly 31 is arranged on the fixed guide rail 100 and clamped between the plurality of sliding wheel assemblies 22, and the transmission assembly 32 is arranged on the driven assembly 31. By arranging the driven assembly 31 on the fixed guide rail 100 and clamped between the plurality of sliding wheel assemblies 22, the weight of the door body can be avoided to fall on the moving rail 21, the burden of the moving rail 21 is reduced, the bending deformation of the moving rail 21 is effectively prevented, and the service life of the sliding door device is prolonged. Since the driven assembly 31 is clamped between the sliding wheel assemblies 22, the door body can be driven by the moving rail 21, so that the door body can move normally along the fixed rail, the shaking and swinging of the driven assembly 31 during movement are reduced, the precise opening and closing of the door are realized, and the movement stability of the entire sliding door device is improved. By arranging the transmission assembly 32 on the driven assembly 31, the door body can be driven by the transmission assembly 32 to cooperate with the driven assembly 31 to move, so that the sliding door device can better maintain its functional integrity when facing external disturbances such as vibration, impact, etc.

[0050] As Figure 1 , Figure 7 and Figure 11As shown, in addition to the features of the above embodiments, the present embodiment is further defined as: the driven assembly 31 comprises a connecting assembly 311 and a plurality of driven wheel assemblies 312, the plurality of driven wheel assemblies 312 are arranged on the fixed guide rail 100, the connecting assembly 311 is arranged on the plurality of driven wheel assemblies 312, and the plurality of driven wheel assemblies 312 are arranged on both sides of the connecting assembly 311. By arranging a plurality of driven wheel assemblies 312 on the fixed guide rail 100, precise guidance can be provided for the door body, and such precise guidance ensures that the door body can move along a predetermined trajectory during opening and closing operations, avoiding random translation or rotation of the door body in the plane, which is crucial for maintaining the correct relative positional relationship between the door body and the fixed guide rail 100. At the same time, the plurality of driven wheel assemblies 312 are distributed on the fixed guide rail 100 and work together to maintain the stability of the door body movement. The plurality of driven wheel assemblies 312 are in contact with the guide rail and can work together to resist disturbances such as minor collisions. On the other hand, the door body has a certain mass and generates a gravitational load. Arranging the plurality of driven wheel assemblies 312 on the fixed guide rail 100 can effectively distribute the gravitational load of the door body and prevent damage to the guide rail or the driven wheel assemblies 312 themselves due to excessive local pressure, ensuring that the fixed guide rail 100 can stably bear the weight of the door body for a long time. Arranging the plurality of driven wheel assemblies 312 on both sides of the connecting assembly 311 ensures that the force on the connecting assembly 311 is more symmetrical, preventing the connecting assembly 311 and the entire door body structure from being twisted and deformed, and ensuring the structural integrity of the door body.

[0051] As Figure 7As shown, in addition to the features of the above embodiments, this embodiment is further defined as: the connecting assembly 311 comprises a connecting block 3111 and a plurality of fixed shafts 3112, the plurality of fixed shafts 3112 are arranged on both sides of the connecting block 3111 and on the driven wheel assembly 312. By arranging the plurality of fixed shafts 3112 on both sides of the connecting block 3111 and on the driven wheel assembly 312, it helps to more evenly distribute the door load, the weight of the door is transmitted to the fixed shaft 3112, and then dispersed to each driven wheel assembly 312. This bilateral distribution method avoids concentrating the load on one side or one point, so that each driven wheel assembly 312 bears relatively balanced pressure, preventing component damage due to excessive local pressure. At the same time, the plurality of fixed shafts 3112 distributed on both sides can reduce the vibration and shaking of the door during movement. When the door moves, any slight imbalance or external disturbance can cause vibration, and the bilateral fixed shaft 3112 and driven wheel assembly 312 can form a more stable structure, absorbing and dispersing these vibration energies through mutual restraint and cooperation, making the door movement more stable, avoiding the impact on the normal use and service life of the door due to shaking.
