Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a protective slider motor. Background Technology

[0002] In the modern smart home industry, with technological advancements and improved living standards, furniture products such as smart sofas, adjustable chairs, adjustable beds, and massage chairs are becoming increasingly popular. These products typically rely on slider motors as drive mechanisms to adjust and move components such as seats and beds. As a core component, the performance and safety of the slider motor directly affect the user experience and safety of the entire product.

[0003] However, a common problem exists in the design of slider motors widely used in the market: the assembly gap between the profile (usually referring to the motor housing or mounting frame) and the plastic liner is relatively large, and there is a lack of effective protective mechanisms. This design deficiency allows larger foreign objects (such as dust, debris, and small items) to easily fall into this gap during use, which may not only interfere with the normal operation of the motor but also cause malfunctions due to accumulation, thus shortening the motor's service life.

[0004] More seriously, due to the lack of necessary protection in this gap, when the push rod (usually driven by a worm gear mechanism to achieve linear motion) is in motion, the user's fingers or other objects may accidentally get into the gap. During the rotation of the worm gear and the lead screw, if a part of the body or an object is caught in the gap, it could cause pinching, scratches, or other safety hazards, seriously threatening the user's personal safety. Utility Model Content

[0005] To overcome at least one of the defects described in the prior art, this utility model provides a protective slider motor. This solves the problem of motor safety during use.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A protective slider motor includes a motor mounting base, a first end cover, a second end cover, a lead screw, a slider, and a guide rail. A motor is mounted on one side of the motor mounting base, and a mounting hole is provided on the side of the motor mounting base adjacent to the motor. The first end cover is installed inside the mounting hole, and the second end cover is located outside the mounting hole. The lead screw and the guide rail are both installed parallel to each other between the first and second end covers. The slider slides on the guide rail and is drivenly connected to the lead screw. The motor also includes a bottom cover, which is assembled between the first and second end covers and is arranged parallel to the side of the lead screw facing away from the guide rail. A gap is formed between the two side edges of the guide rail and the two side edges of the bottom cover. A protective strip is assembled between the first and second end covers and located within the gap. The slider also has a clearance hole for the protective strip to pass through.

[0008] By adopting the above solution, the bottom cover is assembled between the first and second end covers and is parallel to the lead screw on the side away from the guide rail, forming a relatively closed environment. The protective strip is assembled between the first and second end covers and is located in the gap between the guide rail and the bottom cover, further reducing the space where foreign objects may enter, thus effectively preventing the intrusion of larger foreign objects. The presence of the protective strip not only prevents the intrusion of foreign objects but also forms a physical barrier, reducing the possibility of users' fingers or other objects sticking into the gap. The clearance holes on the slider allow the protective strip to pass through, ensuring the smooth movement of the slider on the guide rail without damaging the integrity of the protective strip, thereby maintaining the protective effect.

[0009] Furthermore, the first end cap includes: a first lead screw assembly hole for rotatably connecting with one end of the lead screw; and a first protective strip fixing hole located on both sides of the first lead screw assembly hole for fixing with one end of the protective strip.

[0010] Furthermore, the second end cap includes: a second lead screw assembly hole for rotatably connecting with the other end of the lead screw; and a second protective strip fixing hole located on both sides of the second lead screw assembly hole for fixing with the other end of the protective strip.

[0011] By adopting the above solution, a stable assembly space can be provided for the lead screw and anti-slip strip, which not only facilitates the installation and fixing of the protective strip, but also enhances the sealing effect of the protective strip on the gap. During the operation of the motor, even if it is subjected to external force impact or vibration, the protective strip can maintain its position, thereby ensuring the durability of the protective effect.

[0012] Furthermore, the number of the protective strips is an integer multiple of 2, so that at least one of the protective strips exists in both gaps between the guide rail and the bottom cover.

[0013] By adopting the above solution and installing at least one protective strip in each gap, it can be ensured that the gaps are effectively sealed in both directions during operation of the entire slider motor. This greatly reduces the possibility of foreign objects entering and improves the overall protection performance of the motor.

[0014] Furthermore, the number of the protective strip, the first protective strip fixing hole, and the second protective strip fixing hole are all four, and they are symmetrically distributed on both sides of the lead screw.

[0015] By adopting the above solution, the four protective strips are symmetrically distributed, forming a comprehensive protective barrier that effectively prevents foreign objects from entering the gap between the guide rail and the bottom cover from any direction. This design not only improves the motor's protective performance but also enhances user safety.

[0016] Furthermore, the clearance holes on the slider include a first clearance hole and a second clearance hole, the first clearance hole and the second clearance hole are symmetrically arranged, and two protective strips are inserted into each of the first clearance hole and the second clearance hole.

[0017] By adopting the above solution, when the slider moves on the guide rail, the protective strips in the first and second clearance holes fit together tightly like a zipper, ensuring a dynamic seal between the slider and the protective strips during movement. This design not only prevents foreign objects from entering the gap between the guide rail and the bottom cover, but also reduces gap changes caused by slider movement, thereby improving the overall protective performance of the structure.

[0018] Furthermore, the two protective strips within the first and second clearance holes are spaced apart.

[0019] By adopting the above solution, the system can accommodate the minute displacements generated by the slider during movement, ensuring a consistent sealing effect. The spaced protective strips act like "supports" to hold the slider in place, reducing its swaying during movement. This design enhances the stability of the entire structure, making the slider motor run more smoothly and reliably.

[0020] Furthermore, the first end cap is provided with abutting edges around its perimeter, which are used to abut against the motor mounting base inside the mounting hole.

[0021] By adopting the above solution, the contact between the abutment edge and the motor mounting base ensures the precise positioning of the first end cover during installation. This design prevents the end cover from shifting or tilting during installation, thus guaranteeing the stability and reliability of the entire slider motor. Simultaneously, the abutment edge also serves to fix the end cover, increasing the contact area between the first end cover and the motor mounting base, thereby enhancing the overall structural strength and preventing it from loosening due to vibration during motor operation.

[0022] Furthermore, the slider is provided with a sliding channel for the guide rail to pass through, and the slider is also provided with a screw hole for the lead screw to drive the connection, and the sliding channel and the screw hole are spaced apart.

[0023] By adopting the above solution, the slider can move smoothly on the guide rail and be effectively driven by the lead screw, thereby achieving precise motion control and high-efficiency performance.

[0024] Furthermore, the sliding channel is provided with a number of guide ribs for abutting against the guide rail.

[0025] By employing the above scheme, the precise positioning and guidance of the slider on the guide rail are ensured. Their tight fit with the guide rail prevents the slider from shifting or wobbling during movement, thus ensuring the accuracy of the slider's linear motion. Although the contact area between the guide ribs and the guide rail is relatively small, their materials and design are carefully selected to reduce friction and wear. This helps extend the service life of the slider and guide rail and reduces maintenance costs. The presence of the guide ribs makes the slider's movement on the guide rail smoother. They can absorb and disperse the impact force generated during the slider's movement, thereby reducing vibration and noise and improving the stability of the entire system. As part of the slider, the guide ribs also enhance the overall structural strength of the slider. They can withstand lateral forces from the guide rail, preventing the slider from deforming or being damaged when subjected to external forces.

[0026] In summary, the protective slider motor provided by this utility model has the following technical effects:

[0027] 1. The protective strip is installed in the gap between the guide rail and the bottom cover, forming an effective physical barrier to prevent the user's fingers or other objects from entering the gap when the motor is running, thereby avoiding safety hazards such as pinching and scratching, and greatly improving the safety of the product.

[0028] 2. The design of the bottom cover and protective strip creates a relatively enclosed environment, effectively preventing larger foreign objects such as debris and fragments from falling into the motor, reducing interference from foreign objects on the normal operation of the motor, and extending the service life of the motor.

[0029] 3. The design of the protective strip and bottom cover not only prevents the intrusion of foreign objects, but also reduces the impact of the external environment on the motor's interior, such as humidity and temperature, thereby maintaining the stability of the motor's performance and ensuring the reliability and durability of the product.

[0030] 4. The clearance holes on the slider allow the protective strip to pass through, ensuring smooth movement of the slider on the guide rail without compromising the integrity of the protective strip. This design satisfies the motor's drive requirements while maintaining the protective effect, demonstrating optimized and innovative structural design. Attached Figure Description

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0042] See Embodiment 1 of this utility model. Figures 1-6As shown, a protective slider 5 motor 11 is disclosed, including a motor mounting base 1, a first end cover 2, a second end cover 3, a lead screw 4, a slider 5, a guide rail 6, a bottom cover 7, and a protective strip 8. The motor 11 is mounted on one side of the motor mounting base 1, and the driving end of the motor 11 is drivenly connected to the lead screw 4. A mounting hole 12 is provided on the side of the motor mounting base 1 adjacent to the motor 11. The first end cover 2 is installed inside the mounting hole 12, and the second end cover 3 is located outside the mounting hole 12. The lead screw 4 and the guide rail 6 are both installed between the first end cover 2 and the second end cover, and the lead screw 4 and the guide rail 6 are parallel to each other. Furthermore, the slider 5 is slidably mounted on the guide rail 6 and driven by the lead screw 4. The bottom cover 7 is assembled between the first end cover 2 and the second end cover 3, and is arranged parallel to the side of the lead screw 4 away from the guide rail 6, so that the lead screw 4, guide rail 6, and bottom cover 7 are parallel to each other and spaced apart. A gap 9 is formed between the two side edges of the guide rail 6 and the two side edges of the bottom cover 7. The protective strip 8 is assembled between the first end cover 2 and the second end cover 3 and is located within the gap 9. The slider 5 is also provided with a clearance hole for the protective strip 8 to pass through. Since the bottom cover 7 is assembled between the first end cover 2 and the second end cover 3 and is arranged parallel to the side of the lead screw 4 away from the guide rail 6, a relatively closed environment is formed. The protective strip 8 is assembled between the first end cover 2 and the second end cover 3 and is located within the gap 9 between the guide rail 6 and the bottom cover 7, further reducing the space where foreign objects may enter, thereby effectively preventing the intrusion of larger foreign objects. The presence of the protective strip 8 not only prevents the intrusion of foreign objects, but also forms a physical barrier, reducing the possibility of the user's fingers or other objects sticking into the gap. The clearance hole set on the slider 5 allows the protective strip 8 to pass through, ensuring the smooth movement of the slider 5 on the guide rail 6, while not damaging the integrity of the protective strip 8, thus maintaining the protective effect.

[0043] Specifically, in this embodiment 1, the first end cap 2 includes a first lead screw assembly hole 21 and a first protective strip fixing hole 22. The first lead screw assembly hole 21 is used to rotatably connect with one end of the lead screw 4, and the first protective strip fixing hole 22 is located on both sides of the first lead screw assembly hole 21 and is used to fix one end of the protective strip 8. The second end cap 3 includes a second lead screw assembly hole 31 and a second protective strip fixing hole 32. The second lead screw assembly hole 31 is used to rotatably connect with the other end of the lead screw 4, and the second protective strip fixing hole 32 is located on both sides of the second lead screw assembly hole 31 and is used to fix the other end of the protective strip 8. This arrangement provides a stable assembly space for the lead screw 4 and the anti-slip strip, which not only facilitates the installation and fixing of the protective strip 8, but also enhances the sealing effect of the protective strip 8 on the gap 9. During the operation of the motor 11, even if subjected to external force impact or vibration, the protective strip 8 can maintain its position unchanged, thereby ensuring the durability of the protective effect.

[0044] Preferably, the slider 5 is provided with a sliding channel 53 for the guide rail 6 to pass through, and the slider 5 is also provided with a screw hole 54 for the lead screw 4 to drive and connect. The sliding channel 53 and the screw hole 54 are spaced apart to ensure that the slider 5 can move smoothly on the guide rail 6 and be effectively driven by the lead screw 4, thereby achieving precise motion control and high-efficiency performance.

[0045] Before use, install the motor 11 onto the motor mounting base 1 and secure it. Install the first end cover 2 into the mounting hole 12 of the motor mounting base 1, ensuring that the first lead screw assembly hole 21 is aligned with one end of the lead screw 4, and secure it with bolts or other fasteners. Assemble the bottom cover 7 between the first end cover 2 and the second end cover 3, ensuring that the bottom cover 7 is parallel to the side of the lead screw 4 away from the guide rail 6 and forms a gap 9 with the two side edges of the guide rail 6. Assemble the protective strip 8 into the gap 9 between the first end cover 2 and the second end cover 3. It should be noted that the number of the protective strips 8 is an integer multiple of 2, so that at least one protective strip 8 exists in both gaps 9 between the guide rail 6 and the bottom cover 7. Secure the protective strip 8 with bolts or other fasteners through the first protective strip fixing hole 22 and the second protective strip fixing hole 32. Slide the slider 5 onto the guide rail 6, ensuring that the guide rail 6 passes through the sliding channel 53 of the slider 5, and ensure that the screw hole 54 is aligned with the lead screw 4 so that the lead screw 4 drives the slider 5 to move. Simultaneously, ensure that the clearance holes on the slider 5 can accommodate the protective strips 8 to maintain their protective effect. Finally, install the second end cap 3 outside the mounting holes 12 of the motor mounting base 1, ensuring that the second lead screw assembly hole 31 is aligned with the other end of the lead screw 4, and secure it with bolts or other fasteners. By providing at least one protective strip 8 in each gap 9, it can be ensured that the gaps 9 are effectively sealed in both directions during operation of the entire slider 5 motor 11. This greatly reduces the possibility of foreign objects entering and improves the overall protective performance of the motor 11.

[0046] In this embodiment 1, there are four protective strips 8, four first protective strip fixing holes 22, and four second protective strip fixing holes 32, symmetrically distributed on both sides of the lead screw 4. The four protective strips 8 symmetrically distributed form an all-around protective barrier, effectively preventing foreign objects from entering the gap 9 between the guide rail 6 and the bottom cover 7 from any direction. This design not only improves the protective performance of the motor 11 but also enhances user safety. Correspondingly, the clearance holes on the slider 5 include a first clearance hole 51 and a second clearance hole 52. The first clearance hole 51 and the second clearance hole 52 are symmetrically arranged, and two protective strips 8 are inserted into each of the first clearance hole 51 and the second clearance hole 52. When the slider 5 moves on the guide rail 6, the protective strips 8 in the first clearance hole 51 and the second clearance hole 52 fit tightly like a zipper, ensuring a dynamic seal between the slider 5 and the protective strips 8 during movement. This design not only prevents foreign objects from entering the gap 9 between the guide rail 6 and the bottom cover 7 but also reduces the change in the gap 9 caused by the movement of the slider 5, thereby improving the overall protective performance of the structure.

[0047] In some embodiments, to avoid contact between the protective strips 8 and thus increase the gap 9 between the protective strips 8 and the bottom cover 7 or guide rail 6, the two protective strips 8 within the first clearance hole 51 and the second clearance hole 52 are spaced apart. This allows for the adaptation to minor displacements of the slider 5 during movement, ensuring a consistent sealing effect. The spaced protective strips 8 act like "supports" to support the slider 5, reducing swaying during movement. This design enhances the stability of the entire structure, making the slider 5 motor 11 operate more smoothly and reliably.

[0048] In some embodiments, to improve the stability of the first end cover 2, an abutment edge 23 is provided around the first end cover 2. The abutment edge 23 is used to abut against the motor mounting base 1 in the mounting hole 12. The abutment edge 23 and the motor mounting base 1 ensure the precise positioning of the first end cover 2 during installation. This design prevents the end cover from shifting or tilting during installation, thereby ensuring the stability and reliability of the entire slider 5 motor 11. At the same time, the abutment edge 23 also serves to fix the end cover, increasing the contact area between the first end cover 2 and the motor mounting base 1, thereby enhancing the strength of the entire structure and preventing it from loosening due to vibration during the operation of the motor 11.

[0049] In some embodiments, to improve the sliding stability of the slider 5, a plurality of guide ribs 531 for abutting against the guide rail 6 are provided in the sliding channel 53. The guide ribs 531 may be located on one or more sidewalls within the sliding channel 53. Preferably, in this embodiment 1, the sliding channel 53 is rectangular, and one side has a concave arc-shaped wall to avoid the screw hole 54. The guide ribs 531 are provided on all straight sidewalls within the sliding channel 53. This ensures the precise positioning and guidance of the slider 5 on the guide rail 6. Their tight fit with the guide rail 6 prevents the slider 5 from shifting or wobbling during movement, thereby ensuring the linear motion accuracy of the slider 5. The contact area between the guide ribs 531 and the guide rail 6 is relatively small, but their materials and design are carefully selected to reduce friction and wear. This helps extend the service life of the slider 5 and the guide rail 6 and reduces maintenance costs. The presence of the guide ribs 531 makes the movement of the slider 5 on the guide rail 6 smoother. They can absorb and disperse the impact force generated during the movement of slider 5, thereby reducing vibration and noise and improving the stability of the entire system. As part of slider 5, guide ribs 531 also enhance the overall structural strength of slider 5. They can withstand the lateral force from guide rail 6 and prevent slider 5 from deforming or being damaged when subjected to external forces.

[0050] In summary, the protective slider 5 and motor 11 provided by this utility model have the following technical effects:

[0051] 1. The protective strip 8 is installed in the gap 9 between the guide rail 6 and the bottom cover 7, forming an effective physical barrier to prevent the user's fingers or other objects from entering the gap when the motor 11 is running, thereby avoiding safety hazards such as pinching and scratching, and greatly improving the safety of the product.

[0052] 2. The design of the bottom cover 7 and the protective strip 8 creates a relatively closed environment, which effectively prevents larger foreign objects such as debris and fragments from falling into the motor 11, reduces the interference of foreign objects on the normal operation of the motor 11, and extends the service life of the motor 11.

[0053] 3. The design of the protective strip 8 and the bottom cover 7 not only prevents the intrusion of foreign objects, but also reduces the impact of the external environment on the inside of the motor 11, such as humidity and temperature, thereby maintaining the stability of the motor 11's performance and ensuring the reliability and durability of the product.

[0054] 4. The clearance holes on the slider 5 allow the protective strip 8 to pass through, ensuring smooth movement of the slider 5 on the guide rail 6 without compromising the integrity of the protective strip 8. This design satisfies the driving requirements of the motor 11 while maintaining the protective effect, demonstrating the optimization and innovation of the structural design.

[0055] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
