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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] A precision electric linear actuator based on microcontroller control, such as... Figures 1-7 As shown, the device includes a mounting body 20. A housing 1 is connected to the outer wall of the mounting body 20 by screws. A protective housing 2 is fixedly connected to the other outer wall of the mounting body 20. A drive motor 4 is installed on the outer wall of the mounting body 20 and directly below the protective housing 2. A mounting housing 3 is fixedly connected to the end of the drive motor 4 away from the mounting body 20. A Hall plate 14 is installed inside the mounting housing 3. A drive chip 21 is installed inside the mounting housing 3 near the Hall plate 14. A microcontroller body 18 is provided inside the mounting housing 3 near the drive chip 21.

[0029] The output terminal of Hall plate 14 is electrically connected to the input terminal of driver chip 21, and the output terminal of driver chip 21 is electrically connected to the input terminal of microcontroller body 18.

[0030] A support plate 19 is fixedly installed inside the outer casing 1. A transmission assembly is provided on the outer wall of the support plate 19. The transmission assembly includes a first transmission gear 5, a second transmission gear 11, and a third transmission gear 12. The first transmission gear 5, the second transmission gear 11, and the third transmission gear 12 are all rotatably connected to the outer wall of the support plate 19 via shafts, and the first transmission gear 5, the second transmission gear 11, and the third transmission gear 12 are all meshed with each other. A transmission shaft 9 is rotatably connected to the outer wall of the support plate 19, and one end of the transmission shaft 9 is fixedly connected to the first transmission gear 5.

[0031] A lead screw 8 is fixedly connected to the end of the drive shaft 9 away from the bearing plate 19. A lead screw sleeve 7 is sleeved on the outside of the lead screw 8. A movable rod 6 is threadedly connected to the outer wall of the lead screw sleeve 7. The lead screw 8 is driven to rotate by the transmission mechanism, which can drive the lead screw sleeve 7 to move linearly, thereby driving the movable rod 6 to move, so that the electric push rod can perform telescopic movement.

[0032] In use, the user programs the required operating parameters for the electric linear actuator via an external display screen. This causes the drive chip 21 to receive commands, read the pulses output by the Hall plate 14, and control the rotation of the drive motor 4 via the microcontroller 18. The drive motor 4 then drives the transmission components, causing the transmission shaft 9 to rotate, which in turn causes the lead screw 8 to rotate, moving the lead screw sleeve 7. This causes the movable rod 6 to extend and retract linearly, enabling the electric linear actuator to perform precise push-pull actions. It automatically stops when the required stroke is reached. The extension or retraction distance of the actuator can be displayed on the screen, allowing the user to intuitively understand the extension or retraction distance, improving human-machine interaction. Furthermore, the electric linear actuator can be controlled to stop at any point within the designed stroke, meeting actual customer needs.

[0033] One end of the movable rod 6 is away from the drive shaft 9 and the other end is connected to a connector 17 by a thread. The outer wall of the connector 17 has a through-hole 15, through which the electric push rod can be connected and installed with an external device that can be pushed.

[0034] One end of the drive motor 4 is fixedly connected to a power cord 10, which provides power to the drive motor 4. A sealing gasket 16 is fixedly installed on the outside of the mounting body 20. The sealing gasket 16 is made of silicone, which can fill the gap between the outer shell 1 and the protective shell 2, improve the sealing performance, and has good waterproof and dustproof performance. The protective shell 2 is made of aluminum alloy, which can provide good protection for the movable rod 6 and effectively improve the service life of the push rod.
