The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0027] like Figure 1-4As shown in the embodiment of this utility model, an ultralight linear motor includes a plug sleeve 10, a stator assembly 20, and a mover assembly 30. The plug sleeve 10 is disposed at both ends of the stator assembly 20, and two sets of stator assemblies 20 are provided. The mover assembly 30 is movably mounted on the two sets of stator assemblies 20. A plug connector 11 is provided on the plug sleeve 10, and a sealing element 21 and an anti-collision element are provided on the stator assembly 20 near the mover assembly 30. 22. The mover assembly 30 includes a mover element 31, a transmission rod 32, and a transmission sleeve 33. The mover element 31 is disposed on the transmission sleeve 33, and the transmission sleeve 33 is disposed on the transmission rod 32. Both ends of the transmission sleeve 33 abut against the anti-collision element 22. Both ends of the transmission rod 32 pass through the mover assembly 30 and the stator assembly 20. The transmission rod 32 is inserted into the insertion sleeve 10 and electrically connected to the insertion connector 11 inside the insertion sleeve 10. In this embodiment, by using insert sleeves 10 at both ends of the stator assembly 20, and inserting the transmission rod 32 into the insert sleeves 10 and electrically connecting it to the connector 11, a convenient and stable electrical connection is achieved, ensuring the stability of current transmission and thus improving the overall reliability of the linear motor operation and reducing the probability of failure due to unstable connection. Furthermore, the layout of the two sets of stator assemblies 20 in conjunction with the mover assembly 30 provides a stable track for the mover assembly 30, allowing it to be smoothly mounted and moved on the two sets of stator assemblies 20, effectively improving the motor's performance. The motor's operating efficiency and precision are improved. The sealing element 21, located near the mover assembly 30 on the stator assembly 20, effectively prevents dust, moisture, and other impurities from entering the motor, extending its service life and reducing wear and short-circuit risks caused by impurities. The anti-collision element 22 prevents excessive movement of the mover assembly 30 during its movement, providing buffering and protection and preventing damage from hard collisions between components. This further enhances the motor's stability and durability, resulting in a compact and highly practical structure.
[0028] like Figure 1 As shown, the outer wall of the plug-in sleeve 10 is covered with an insulating layer. Two sets of side grooves 12 are provided near the insulating layer on both sides of the plug-in sleeve 10. In this embodiment, the insulating layer covering the outer wall of the plug-in sleeve 10 effectively provides insulation, preventing current leakage and ensuring the safety of equipment operation and personnel. The two sets of opposing side grooves 12 near the insulating layer reduce the overall weight of the plug-in sleeve 10, meeting the lightweight requirements of ultra-light linear motors. Furthermore, the side grooves 12 provide some heat dissipation, helping to reduce the heat generated during equipment operation and improving the stability and service life of the motor.
[0029] like Figure 2 As shown, an assembly ring 13 is provided on the insert sleeve 10 near the stator assembly 20. Assembly grooves 14 are provided at both ends of the assembly ring 13, and a clearance groove 15 is provided on the assembly ring 13 away from the assembly grooves 14. In this embodiment, the assembly grooves 14 at both ends of the assembly ring 13 provide precise assembly positioning and installation space for related components, facilitating tight and stable cooperation with other parts and improving the assembly accuracy and stability of the entire linear motor structure. The clearance groove 15 away from the assembly grooves 14 effectively prevents interference and collision between the assembly ring 13 and surrounding components during motor operation, reducing unnecessary wear and potential malfunctions.
[0030] The assembly groove 14 is a raised groove, and the clearance groove 15 is a recessed groove. In this embodiment, the raised assembly groove 14 can better fit with the corresponding component, providing a stable assembly foundation, enhancing connection stability, ensuring that the components will not easily loosen during operation, and improving the overall structural reliability. The recessed clearance groove 15 provides sufficient space for other components, avoids mutual interference, and ensures that each component can operate smoothly.
[0031] like Figures 3 to 4 As shown, the plug-in sleeve 10 has a plug-in groove 16 near the plug-in connector 11. Limiting side grooves 17 are provided on both inner walls of the plug-in groove 16. The plug-in connector 11 is disposed within the plug-in groove 16 and is limited by the limiting side grooves 17. In this embodiment, the cooperation between the plug-in groove 16 and the plug-in connector 11 achieves a stable connection between components, enabling reliable assembly of all parts of the ultralight linear motor and ensuring the overall structural stability of the motor. It also ensures that the relative positions of each component are fixed, preventing loose connections from affecting motor performance, thereby ensuring the efficient and stable operation of the ultralight linear motor.
[0032] The connector 11 is provided with a plug pin 112. A limit latch 113 is provided near the plug pin 112 on the connector 11. A sensor light 114 is provided on the connector 11 away from the plug pin 112. The sensor light 114 is used for sensing by the connector 11. The limit latch 113 cooperates with the limiting side groove 17. In this embodiment, the plug pin 112 on the connector 11 realizes the electrical connection function, transmitting power and signals for the normal operation of the motor. The limit latch 113 near the plug pin 112 cooperates with the limiting side groove 17 to play a role in precise positioning and stable connection, ensuring that the plug is accurately positioned when inserted, avoiding loosening or displacement, and improving connection stability and reliability. The sensor light 114 away from the plug pin 112 can sense the status of the connector 11, providing intuitive feedback on whether the connector 11 is properly connected, powered, etc., allowing users to quickly understand the working status and promptly detect abnormalities, thus improving the convenience of equipment use and maintenance efficiency.
[0033] The stator assembly 20 includes a stator base 23, on which a stator sleeve 24 is disposed. A stator assembly ring 13 is disposed on the stator base 23 near the stator sleeve 24. A sealing groove 241 is disposed within the stator sleeve 24, and an anti-collision groove 131 is disposed within the positioning assembly ring 13. A sealing element 21 is disposed within the sealing groove 241, and an anti-collision element 22 is disposed within the anti-collision groove 131. In this embodiment, the stator sleeve 24 and stator assembly ring 13 disposed on the stator base 23 provide a reasonable structural layout and a basic framework for the stable operation of the motor. The sealing groove 241, disposed within the stator sleeve 24 and working in conjunction with the sealing element 21, effectively prevents external dust, moisture, and other impurities from entering the motor, ensuring the normal working environment of the internal components and extending their service life. The anti-collision groove 131, disposed within the positioning assembly ring 13 and fitted with the anti-collision element 22, acts as a buffer when the motor is subjected to vibration or impact, reducing collision damage between components and improving the overall stability and reliability of the motor.
[0034] Sealing element 21 has sealing limiting rings 211 at both ends. One end of the sealing limiting ring 211 abuts against the assembly ring 13, and the other end abuts against the anti-collision element 22. The anti-collision element 22 is an elastic ring, and multiple elastic rings are provided, each with a different ring size. In this embodiment, the sealing limiting rings 211 at both ends of the sealing element 21 abut against the assembly ring 13, which can accurately position the sealing element 21, ensuring its accurate installation position, enhancing the stability and reliability of the seal, and preventing the seal from shifting and affecting the sealing effect. The other end abuts against the anti-collision element 22, which provides buffer protection. The anti-collision element 22 uses multiple elastic rings of different sizes, which can adapt to different levels of impact force.
[0035] The stator sleeve 24 has slides 25 at both ends. One end of the assembly groove 14 slides along the slide 25 to insert the plug-in sleeve 10 onto the stator assembly 20, so that the plug-in connector 11 can connect with the mover assembly 30. In this embodiment, by sliding one end of the assembly groove 14 along the slide 25, the plug-in sleeve 10 can be accurately and smoothly inserted into the stator assembly 20, effectively reducing the installation difficulty and improving the assembly efficiency; it ensures a stable connection between the plug-in connector 11 and the mover assembly 30, guarantees the stability of signal transmission and energy conversion inside the ultra-light linear motor, and improves the overall performance and operational reliability of the motor.

The moving ring 36 is movably sleeved on the transmission rod 32 to drive the moving elements 31 and the transmission sleeve 33 for transmission. In this embodiment, the multiple moving elements 31, in conjunction with the multiple transmission rings 34 and transmission grooves 35 on the transmission sleeve 33, effectively increase the stability and reliability of the transmission, enabling more precise power transmission, reducing power loss and deviation. The moving ring 36, sleeved between the transmission rod 32 and the moving elements 31 and movable, provides greater flexibility during transmission, smoothly driving the moving elements 31 and the transmission sleeve 33 for transmission, improving the overall response speed and operating efficiency of the motor. The structure is compact and highly practical.
