DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0034] With reference to Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: parallel motor of car seat with memory function, including shell 1, the bottom fixed connection of shell 1 has brush holder 3, the inside bottom fixed connection of brush holder 3 has rear axle sleeve 4, the inside rotation of rear axle sleeve 4 is connected with rotor assembly 5, the outside top of rotor assembly 5 is connected with front axle sleeve 6, the inside fixed connection of shell 1 has a plurality of magnetic tile 7, the inside fixed connection of a plurality of magnetic tile 7 has tile clamp 8, the outside middle upper portion of rotor assembly 5 is connected with plastic ring 9, the top fixed connection of shell 1 has end cover 10, the inside top of front axle sleeve 6 is connected in end cover 10, the inside of brush holder 3 is provided with driving mechanism 2;

[0035] Specifically, the shell 1 serves as the basic structure of the entire motor, which can provide installation and protection space for other components. The brush holder 3 fixedly connected at the bottom of the shell 1 serves as a support and positioning function. The rear shaft sleeve 4 fixedly connected at the inner bottom of the brush holder 3 provides a stable rotating support point for the rotor assembly 5. The rotor assembly 5 is installed inside the rear shaft sleeve 4 and can rotate around the shaft. The outer top of the rotor assembly 5 is rotatably connected to the front shaft sleeve 6, which is fixedly connected to the inner top of the end cover 10. The end cover 10 is fixedly connected to the top of the shell 1, so that the rotor assembly 5 can rotate stably under the support of the front shaft sleeve 6 and the rear shaft sleeve 4. The plurality of magnetic tiles 7 fixedly connected to the inner side of the shell 1 generates a stable magnetic field, providing the necessary magnetic field environment for the operation of the motor. The tile clamp 8 fixedly connected to the inner side of the magnetic tile 7 is used to fix the magnetic tile 7, ensuring that the magnetic tile 7 does not displace during the operation of the motor, ensuring the stability of the magnetic field. The plastic ring 9 fixedly connected to the outer middle and upper part of the rotor assembly 5 serves as an insulation and protection function, which can prevent short circuit between the rotor assembly 5 and other components, and also can reduce the friction between the rotor assembly 5 and other components during rotation. The driving mechanism 2 arranged in the brush holder 3 is the power source of the motor operation. When the driving mechanism 2 is powered on, it will generate an electric current. The electric current is conducted to the rotor assembly 5 through the brush holder 3. Under the action of the magnetic field generated by the magnetic tile 7, according to the principle of electromagnetic induction, the rotor assembly 5 will be affected by electromagnetic force and start to rotate. The rotation of the rotor assembly 5 is supported by the front shaft sleeve 6 and the rear shaft sleeve 4, maintaining a stable rotating state. With the rotation of the rotor assembly 5, the motor can output power, thereby driving the seat components connected thereto to move or adjust in the horizontal direction. When the current direction of the driving mechanism 2 changes, the direction of the electromagnetic force acting on the rotor assembly 5 will also change, thereby realizing the forward and reverse rotation of the motor to meet the adjustment requirements of the seat in different directions, improving the space utilization and fitting the narrow installation space of the seat. The combination of the magnetic tile 7 and the tile clamp 8 makes the magnetic field distribution more uniform and stable, greatly improving the operation efficiency and torque output.

[0036] With reference to Figure 2 , Figure 4 and Figure 6 , the driving mechanism 2 includes a tab fixed block 201 fixedly connected to the inner right end of the brush holder 3. The front and rear sides of the tab fixed block 201 are fixedly connected with power tabs 202. The top of the tab fixed block 201 is fixedly connected with a cover plate 203. The inner front and rear ends of the brush holder 3 are fixedly connected with inductors 204. The outer middle and lower part of the rotor assembly 5 is fixedly connected with a magnetic ring 205. The inner front and left ends of the brush holder 3 are fixedly connected with carbon brushes 206. The top of each carbon brush 206 is fixedly connected with a pressing plate 207. The top front and rear sides of the tab fixed block 201 are fixedly connected with Hall pins 208. The right ends of the two Hall pins 208 are fixedly connected with EMC modules 209.

[0037] Specifically, in the conventional version, the plug fixing block 201 is fixed at the right end of the inner side of the brush holder 3, supporting the power plug 202, which connects to the external power supply, and the current enters the drive mechanism 2 from here. The cover plate 203 on the top of the plug fixing block 201 protects the power plug 202, ensuring stable transmission of current. The inductor 204 at the front and rear ends of the inner side of the brush holder 3 filters and stores energy when the current passes through, releasing it when needed to smooth the current, reduce fluctuations and interference, and ensure stable operation of the motor. The magnetic ring 205 on the outer side of the middle and lower part of the rotor assembly 5, together with the magnetic tile 7 on the inner side of the housing 1, forms a magnetic field system. The magnetic ring 205 rotates with the rotor assembly 5 and interacts with the magnetic field of the magnetic tile 7 to provide power for the motor rotation. The carbon brush 206 on the inner side of the brush holder 3 is responsible for power transmission and commutation. After the current enters through the power plug 202, it is conducted to the rotor assembly 5 through the carbon brush 206. When the rotor assembly 5 rotates, the carbon brush 206 constantly contacts different parts to achieve current commutation, allowing the motor to rotate continuously and stably. The pressing plate 207 fixes the carbon brush 206 to ensure good contact with the rotor assembly 5 and reliable current transmission.

[0038] In the memory version, the addition of the Hall pin 208 and the EMC module 209 enables the motor to have memory function. Compared to the conventional version without the Hall pin 208 and the EMC module 209, it better meets the seat adjustment needs. The Hall pin 208 is fixed on the top of the plug fixing block 201, and the EMC module 209 is connected to the right end of the Hall pin 208. It effectively suppresses electromagnetic interference generated during motor operation, ensuring electromagnetic compatibility between the motor internal circuit and external devices, avoiding the impact of electromagnetic interference on motor control and other electronic devices, and ensuring stable and low-noise operation of the motor. At the same time, it can accurately detect the position and speed information of the rotor assembly 5 and transmit these signals to the EMC module 209 through the Hall pin 208. The EMC module 209 accurately controls the operation of the motor based on this information, enabling the memory version to accurately adjust the seat position. When the motor is installed on the seat rail position through the flexible shaft and connected to the power supply, the operator presses the switch as needed, causing the motor to drive the seat to move back and forth in the rail. Due to the effect of the EMC module 209, the motor operates with low noise and low power consumption, allowing the seat with memory to be stopped at any stroke and set to a certain position as needed, achieving the memory function.

[0039] Referring to Figure 2 , Figure 3 and Figure 5The outer side of the rotor assembly 5 is fixedly connected with an elastic body 11, and the elastic body 11 is designed in a cylindrical shape. The top of the elastic body 11 is fixedly connected with a graphite gasket 1, and the top of the graphite gasket 1 is attached to the bottom of the front shaft sleeve 6. The bottom of the magnetic ring 205 is provided with a graphite gasket 2, and the bottom of the graphite gasket 2 is attached to the top of the rear shaft sleeve 4. The outer side of the end cover 10 is fixedly connected with a shock pad 14, and the top of the shock pad 14 is designed in a smooth shape. The rear shaft sleeve 4 and the front shaft sleeve 6 are matched in size, and the outer sides of the rear shaft sleeve 4 and the front shaft sleeve 6 are both designed in a wear-resistant process. The shell 1, the brush holder 3 and the end cover 10 are all designed in a flame-retardant process, and the outer sides of the shell 1, the brush holder 3 and the end cover 10 are all designed in an insulation design.

[0040] Specifically, the elastic body 11 fixedly connected to the outer side of the rotor assembly 5 is designed in a cylindrical shape, which can effectively buffer the axial vibration generated by the rotor assembly 5 when rotating. When the rotor assembly 5 rotates and generates an axial displacement trend, the elastic body 11 can absorb vibration energy by virtue of its elastic deformation, thereby reducing the influence of vibration on the overall structure of the motor. The graphite gasket 1 fixedly connected to the top of the elastic body 11 is attached to the bottom of the front shaft sleeve 6. Since the graphite gasket 1 has good lubricity, it can reduce the friction coefficient between the rotor assembly 5 and the front shaft sleeve 6, thereby reducing wear and ensuring smoother rotation of the rotor assembly 5. Meanwhile, the graphite gasket 1 further assists the elastic body 11 in reducing vibration transmission. The graphite gasket 2 provided at the bottom of the magnetic ring 205 is attached to the top of the rear shaft sleeve 4. Like the graphite gasket 1, the graphite gasket 2 provides lubrication for the contact part of the magnetic ring 205 and the rear shaft sleeve 4, thereby reducing friction between the magnetic ring 205 and the rear shaft sleeve 4 when the magnetic ring 205 rotates with the rotor assembly 5, prolonging the service life of the magnetic ring 205 and the rear shaft sleeve 4, and helping to maintain stable operation of the motor magnetic field system. The shock pad 14 fixedly connected to the outer side of the end cover 10 is designed in a smooth shape at the top. When the motor is working, the shock pad 14 can absorb the radial vibration generated by the motor during operation, thereby avoiding transmission of vibration to surrounding components. The smooth top can reduce the risk of damage caused by accidental contact with other components, thereby further improving the stability and safety of motor operation. The rear shaft sleeve 4 and the front shaft sleeve 6 are matched in size and are both designed in a wear-resistant process. The matched size ensures that the front shaft sleeve 6 and the rear shaft sleeve 4 can be accurately matched during installation and operation of the rotor assembly 5, thereby providing stable support. The wear-resistant process greatly improves the service life of the shaft sleeves, reduces wear caused by long-term use and frequent friction, and ensures long-term stable operation of the motor. The shell 1, the brush holder 3 and the end cover 10 are all designed in a flame-retardant process and are all designed in an insulation design. The flame-retardant process can effectively prevent the spread of fire when an abnormally high temperature or even a fire hazard occurs inside the motor, thereby ensuring safety in use. The insulation design can prevent current leakage and avoid accidents caused by electric shock, while maintaining normal operation of the internal circuit system of the motor.
