Description

Technical Field

[0001] This application relates to the field of linear actuator motor technology, specifically a protection structure for the output end of a linear actuator motor. Background Technology

[0002] With the accelerating pace of industrial automation, linear actuator motors, as key drive devices for achieving linear reciprocating motion, are widely used in various mechanical equipment, automated production lines, and smart homes. When a linear actuator motor is working, its output end bears the important responsibility of converting the internal rotational motion of the motor into linear motion and transmitting power to the external load.

[0003] In real-world industrial production scenarios, such as industrial workshops, dust is freely circulating. These tiny particles are highly penetrating and can infiltrate the precision gaps at the output end of a linear actuator motor. As the motor continues to operate, dust accumulates in these gaps, significantly increasing the coefficient of friction between components over time. This increase in friction directly leads to a rapid acceleration of component wear, drastically shortening the equipment's lifespan and significantly increasing maintenance costs and replacement frequency. Therefore, it is necessary to provide a protective structure for the output end of a linear actuator motor to address these issues.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a protective structure for the output end of a linear actuator motor, which solves the problem that in industrial production, dust can easily enter the gaps at the output end of the linear actuator motor, causing wear, shortening its lifespan, and increasing costs, thus requiring a protective structure to solve this problem.

[0006] The technical solution adopted by this application to solve its technical problem is: a protective structure for the output end of a linear actuator motor, including an actuator motor assembly having a rod sleeve with a telescopic end; a dustproof assembly installed on the rod sleeve, the dustproof assembly having a dustproof part for blocking dust from the gap between the telescopic end and the rod sleeve, the dustproof part consisting of a fixed half-ring and a sponge block, a docking part for installing the dustproof part, and a torsion spring for initially limiting the position of the docking part.

[0007] Furthermore, the dustproof component includes mounting portions installed on both sides of the rod sleeve, and a fixing seat is mounted on the mounting portion by fasteners. The fixing seat has a fixing shaft that passes through the fixing seat, and the fixing shaft has limiting portions at both ends.

[0008] Furthermore, two sets of rotating parts are movably sleeved on the fixed shaft, and the torsion spring is disposed between the two sets of rotating parts and the two sets of limiting parts. The torsion spring is movably sleeved on the fixed shaft, with one end connected to the limiting part and the other end connected to the rotating part. One end of the two sets of rotating parts is connected to a connecting part, and the mating part is installed at one end of the connecting part.

[0009] Furthermore, the docking part has an arc-shaped opening groove, and a slot is provided on the opening groove. The slot is arc-shaped, and the dustproof part is inserted into the slot.

[0010] Furthermore, the sides of the two sets of fixed semi-rings that are in close contact with each other are made of silicone material.

[0011] Furthermore, a fixing pin is inserted into the docking part, a through hole is opened on the fixing half ring for the fixing pin to pass through, a symmetrically arranged protrusion is provided on the fixing pin near the lower end, an insertion hole adapted to the diameter of the fixing pin is opened at one end of the rod sleeve, a threaded groove is opened on the fixing pin, a threaded hole adapted to the threaded groove is opened on one side of the docking part, and a through hole is opened on the other side of the docking part.

[0012] Furthermore, the bump is flexibly designed.

[0013] The beneficial effects of this application are as follows: The linear actuator motor output end protection structure provided by this application allows the fixed half-ring to be pulled out by rotating the docking part, thereby enabling the cleaning of the sponge block attached to it and ensuring its continuous dustproof performance. During operation, the various parts of the dustproof component work together. In the initial state, the sponge block is squeezed and adsorbs dust, while the fixed half-ring blocks dust from gaps by using silicone sealant. This effectively protects the working environment of the internal transmission components of the motor and extends the overall service life of the motor.

Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figures 1-6 As shown, this application provides a protection structure for the output end of a linear actuator motor, including an actuator motor assembly 1. The actuator motor assembly 1 includes a sleeve 11 with a telescopic end 15 to achieve linear displacement output for external work. The bottom of the sleeve 11 has a base 12, and a motor body 13 is fixedly installed on the base 12. The motor body 13 is electrically connected to an external power source through a connecting wire 14.

[0028] When the external power supply is turned on, the current flows orderly into the motor body 13 along the connecting wire 14. The motor body 13 operates based on the fundamental principle of electromagnetic induction; its internal stator windings generate a rotating magnetic field under the excitation of the current. This rotating magnetic field serves as the driving source, driving the rotor to rotate in a circular path through the action of electromagnetic force. Because a specific mechanical connection is established between the motor body 13 and other transmission components inside the push rod motor assembly 1, the rotor's rotational motion can be precisely and efficiently converted into linear motion through a series of mechanical transmission mechanisms.

[0029] A dustproof component 2 is installed on the rod sleeve 11 to enhance the protection performance of the output end of the linear actuator motor. The dustproof component 2 includes mounting parts 21 fixedly installed on both sides of the rod sleeve 11 away from the base 12. The mounting parts 21 serve as basic connecting parts, providing stable support points for the installation of subsequent components. A fixing seat 22 is installed on the mounting parts 21 by fasteners. The fixing seat 22 has a fixing shaft 23 that passes through the fixing seat 22. The fixing shaft 23 has limiting parts (not shown in the figure) at both ends. The function of the limiting parts is to axially limit the components subsequently installed on the fixing shaft 23, ensuring the positional stability of each component during operation.

[0030] Meanwhile, two sets of rotating parts 25 are movably sleeved on the fixed shaft 23. The two sets of rotating parts 25 can rotate flexibly around the fixed shaft 23, and a torsion spring 24 is provided between the two sets of rotating parts 25 and the two sets of limiting parts. The torsion spring 24 is also movably sleeved on the fixed shaft 23, with one end connected to the limiting part and the other end connected to the rotating part 25.

[0031] Meanwhile, a connecting part 26 is fixedly connected to one end of the two sets of rotating parts 25, and a docking part 27 is fixedly installed at one end of the connecting part 26. The docking part 27 has an arc-shaped opening groove (not shown in the figure), and a slot 28 is provided on the opening groove. The slot 28 is arc-shaped, and a fixing half ring 29 is placed in the slot 28. The fixing half ring 29 has a sponge block 210, and the fixing half ring 29 and the sponge block 210 are combined here to form a dustproof part.

[0032] It should be noted that the two sets of mating parts 27 are adapted to approach each other and achieve mating under the action of the torsion spring 24 through the rotating part 25. After the two are mated, they can be combined to form a complete ring structure, which can be tightly fitted onto the telescopic end 15 of the rod sleeve 11. At this time, the sponge block 210 will be compressed to a certain extent, thus achieving a tight fit with the surface of the telescopic end 15. In addition, the side of the two sets of fixed semi-rings 29 that are in close contact with each other is made of silicone material. Silicone material has good flexibility and sealing properties, which allows the two sets of mating parts 27 to fit tightly when mated, effectively reducing gaps and improving the overall dustproof effect.

[0033] In actual use, after repeated use of the sponge block 210, it can be cleaned to ensure its dustproof performance remains consistent. The specific steps are as follows: First, rotate the connecting part 27 around the rotation axis of the connected rotating part 25 until the connecting part 27 and the sleeve 11 are perpendicular to each other. In this position, the limiting state of the fixed half-ring 29 in the slot 28 changes, making it operable. Then, the fixed half-ring 29 can be smoothly pulled out of the slot 28 along its axial direction. Since the sponge block 210 is tightly attached to the fixed half-ring 29, the sponge block 210 is exposed as the fixed half-ring 29 is pulled out, allowing for targeted cleaning to restore its good dustproof performance and maintain the efficient operation of the linear actuator motor output end protection structure.

[0034] When the telescopic end 15 of the linear actuator motor's sleeve 11 extends or retracts, the various parts of the dustproof assembly 2 work together. In the initial state, under the influence of the torque of the torsion spring 24, the two sets of rotating parts 25 drive the connecting part 26 and the docking part 27 to a position close to each other. The two sets of docking parts 27 dock together to form a ring structure and fit onto the telescopic end 15. At this time, the sponge block 210 is squeezed tightly against the surface of the telescopic end 15, which can effectively adsorb dust particles that may come close, playing a primary dustproof role. The two sets of fixed half rings 29 fit tightly together, and with the sealing properties of the silicone material, they further prevent dust from entering from the docking gap. When the telescopic end 15 extends, the connecting part 26 drives the docking part 27 to overcome the torque of the torsion spring 24 and rotate with the rotating part 25 around the fixed axis 23 to both sides, providing space for the extension of the telescopic end 15. During this process, the fixed half ring 29 and the sponge block 210 also move accordingly. When the telescopic end 15 retracts, the torsion spring 24 releases its elastic potential energy, pushing the rotating part 25, the connecting part 26, and the docking part 27 to quickly reset. The two sets of docking parts 27 dock together again to form a ring structure that fits onto the telescopic end 15. The sponge block 210 re-adhere tightly to the surface of the telescopic end 15, and the fixing half ring 29 adheres tightly, continuously providing all-round, multi-layer dust protection for the telescopic end 15 of the rod sleeve 11, ensuring that the internal transmission components of the linear actuator motor output end operate stably in a clean environment, and effectively extending the service life of the motor.

[0035] To ensure the stability of the sponge block 210 within the slot 28, and also to ensure the stability of the mating of the two sets of mating parts 27, such as Figure 6As shown, a fixing pin 212 is inserted into the docking part 27, and a through hole for the fixing pin 212 to pass through is provided on the fixing half ring 29. The fixing pin 212 has symmetrically arranged protrusions 213 near the lower end. The protrusions 213 are flexibly arranged. At one end of the sleeve 11, an insertion hole (not shown in the figure) adapted to the diameter of the fixing pin 212 is provided. A threaded groove 214 is provided near the upper end of the fixing pin 212. A screw hole (not shown in the figure) adapted to the threaded groove 214 is provided on one side of the docking part 27. A through hole 211 for the fixing pin 212 to pass through is provided on the other side of the docking part 27.

[0036] In actual use, the two sets of docking parts 27 are brought close to each other by the torsion spring 24. Then, by passing the fixing pin 212 through the threaded groove 214 and the through hole 211 in sequence, and inserting it into the insertion hole, the threaded groove 214 on the fixing pin 212 is close to the threaded hole. Then, by tightening the fixing pin 212, the protrusion 213 is screwed into the insertion hole.

[0037] In practical applications, the two sets of mating parts 27 naturally approach and mate under the torque of the torsion spring 24. After this mating process is completed, the fixing operation begins. First, the fixing pin 212 is passed through the threaded groove 214 and the through hole 211 in a specific order, and finally inserted into the insertion hole at one end of the sleeve 11. At this time, the threaded groove 214 on the fixing pin 212 is exactly close to the threaded hole on the side of the mating part 27. Then, the fixing pin 212 is tightened. As the fixing pin 212 rotates, the protrusion 213 at its lower end also rotates synchronously into the insertion hole.

[0038] From a working principle perspective, when the fixing pin 212 is tightened, a threaded connection is formed between the threaded groove 214 and the threaded hole. This connection provides a strong axial clamping force, effectively preventing the fixing pin 212 from shifting in the axial direction, thereby firmly connecting the mating part 27 and the sleeve 11 together, significantly enhancing the stability of the two sets of mating parts 27 during mating. Meanwhile, the flexible protrusion 213 at the lower end of the fixing pin 212, during the screwing into the insertion hole, comes into close contact with the inner wall of the insertion hole and undergoes a certain degree of compression deformation. Due to the flexible nature of the protrusion 213, it can better conform to the irregular surface of the inner wall of the insertion hole, further increasing the friction and contact area, thus stabilizing the fixing pin 212 in the radial direction and preventing it from rotating or shaking within the insertion hole. Simultaneously, this stabilizing method indirectly enhances the stability of the fixing half-ring 29 within the slot 28, allowing the sponge block 210 to continuously and stably perform its dustproof function.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
