Description
Technical Field
[0001] This utility model relates to the field of linear motor application technology, and in particular to a hoisting magnetic levitation automatic door motor. Background Technology
[0002] In modern architectural design, automatic door systems are widely used due to their convenience, aesthetics, and efficiency. Traditional automatic door systems mostly use rotary motors to drive the door, using chains, belts, or gears to open and close the door. However, this traditional method has many shortcomings, such as high operating noise, high maintenance costs, and limited transmission efficiency. Especially in high-end venues, such as five-star hotels, large shopping malls, and upscale office buildings, the requirements for automatic door systems are more stringent. These systems not only require smooth and rapid opening and closing of the door, but also extremely low noise, high energy efficiency, and aesthetic appeal.
[0003] With the advancement of technology, linear motor technology has gradually emerged and demonstrated its unique advantages in multiple fields. Linear motors can directly convert electrical energy into linear motion without the need for intermediate transmission devices, thus greatly improving the system's operating efficiency and stability. Furthermore, linear motors also have advantages such as simple structure, low noise, and convenient maintenance, making them ideal for driving automatic door systems.
[0004] Building upon linear motor technology, the application of magnetic levitation technology further enhances the performance of automatic door systems. Magnetic levitation technology uses magnetic force to enable smooth movement of the door panels without physical contact, further reducing noise and friction loss, and improving the system's energy efficiency and lifespan.
[0005] However, most existing magnetic levitation automatic door systems adopt a bottom-mounted method, meaning the motor and transmission device are installed on the ground or under the threshold. While this installation method meets the basic functional requirements of automatic doors to a certain extent, it falls short in some special application scenarios, such as when maintaining a flat and aesthetically pleasing ground, or when there is limited space under the ground to install the motor and transmission device. Utility Model Content

The suspended design not only allows the motor and transmission device to be installed above, avoiding damage and impact on the ground, but also better adapts to the installation needs of different scenarios, improving the flexibility and applicability of the automatic door system. Furthermore, by combining the advantages of linear motors and magnetic levitation technology, the performance of the automatic door system can be further improved, meeting the stringent requirements of high-end venues.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0031] Example 1
[0032] like Figure 1-5 As shown, a suspended magnetic levitation automatic door motor includes multiple suspension frames 1 installed side by side. The bottom of the suspension frame is open, and a magnetic levitation moving rail assembly 2 is movably installed inside it. Door and window mounting parts 3 are installed at the bottom of the magnetic levitation moving rail assembly 2. Motor slots 4 and moving rail slots 5 are installed on the suspension frame from top to bottom. A cover plate 6 is installed on the side of the outermost suspension frame. A moving rail wheel 24 is rotatably installed on one side of the magnetic levitation moving rail assembly. A sliding rail is installed on the suspension frame corresponding to the position of the moving rail wheel. A linear motor is installed in the motor slot. A door leaf 8 is installed at the bottom of the magnetic levitation moving rail assembly. A permanent magnet group is installed on the magnetic levitation moving rail assembly. A linear drive motor is installed in the motor slot directly above the position of the permanent magnet group. The magnetic levitation moving rail assembly on the multiple suspension frames moves laterally under the drive of the linear drive motor.
[0033] The cover plate 6 has a second slot 27 installed on its top, and a protrusion 28 is installed on the suspension bracket corresponding to the cover plate position. The protrusion 28 cooperates with the second slot. The lower end of the cover plate movably overlaps the magnetic levitation track assembly, and a cleaning brush 9 is installed on the inner side wall of the lower end of the cover plate. By setting a slot on the top of the cover plate and cooperating with the protrusion on the suspension bracket, it can be ensured that the cover plate can be firmly fixed on the suspension bracket during installation, and it is not easy to loosen or fall off. This stable installation structure not only improves the stability of the entire system, but also ensures that the door leaf will not generate noise or affect the operating accuracy due to the shaking of the cover plate during operation. The presence of the cleaning brush can also effectively prevent dust and debris from entering the interior of the magnetic levitation track assembly, avoiding damage to internal parts or affecting the normal operation of the system. Therefore, this design helps to improve the reliability and stability of the entire system, ensuring that the door leaf can operate stably for a long time.

The specific fixed iron plate is used to fix the magnet pieces, which facilitates installation and maintenance.
[0035] The linear drive motor 7 includes multiple stator drive motor assemblies connected in series along the lateral direction. The magnetic levitation track assembly moves continuously laterally under the drive of multiple series-connected stator drive electronic assemblies. Continuous long-distance drive using multiple series-connected stator drive electronic assemblies is suitable for reciprocating motion of large-span moving bodies, with low vibration and noise during transmission. The linear drive motor includes a housing, within which a linear motor is installed. The linear motor includes a stator frame 10, a silicon steel sheet assembly 11, a coil assembly 12, and a Hall sensor 13. The stator frame 10 has mounting slots for mounting the Hall sensor and the silicon steel sheet assembly. The silicon steel sheet assembly is installed in the mounting slots, and mounting teeth 16 are evenly distributed on the silicon steel sheet assembly along the lateral direction of the moving body. The coil assembly is sequentially fitted onto the mounting teeth. 16. The coil assembly includes a coil frame 15, on which a coil is wound; the silicon steel sheet assembly 11 includes multiple silicon steel sheet units 14 spliced together, with dovetail grooves 18 and dovetail protrusions 19 installed at both ends of two adjacent silicon steel sheet units 14 respectively; the silicon steel sheet unit includes multiple silicon steel sheets 20 stacked together, the silicon steel sheets 20 are E-shaped, and multiple arched areas 17 for easy stacking are installed on the surface of the silicon steel sheets. The arched areas are made of the silicon steel sheet material itself and are bent. The specially designed silicon steel sheet assembly facilitates installation and subsequent maintenance and replacement; the stator frame has mutually cooperating slots 30 and protrusions 31 at both ends, and adjacent stator frames are spliced together through slots and protrusions, which facilitates splicing an appropriate number of stator drive motor assemblies according to the drive distance.
[0036] The sliding track includes a first track 22 and a second track 23 installed opposite to each other. The first track is installed above the moving wheel, and the second track is installed below the moving wheel. The first track is integrally formed with the suspension frame. The suspension frame has a track slot corresponding to the position of the second track. The cover plate is designed in an L shape, and the top of the cover plate is installed on the suspension frame through a buckle structure to protect the suspension frame.
