Description

Technical Field

[0001] The utility model relates to the technical field of seat slide mechanisms, and more specifically, it relates to a seat slide mechanism. Background Art

[0002] In the existing technology, the design of seats is often relatively simple. While this simplified design provides basic functions, it also brings some inconveniences in use. The main problems include:

[0003] First of all, the structural design of the existing device lacks flexibility. Users cannot flexibly adjust the angle of the backrest and the longitudinal position of the seat through simple operations. This limitation makes the seat unable to adapt to the physical characteristics and personalized needs of different users, thus affecting the riding comfort and ergonomic adaptability.

[0004] Secondly, in the existing device, the sliding function of the seat is usually achieved through the cooperation of a sliding seat and a slide rail. During long-term use, the inner sides of the sliding seat and the slide rail will wear due to friction, which will lead to unsmooth sliding and even generate noise. In order to maintain the sliding performance of the seat, regular lubrication and maintenance are required. However, in the existing technology, this maintenance usually relies on manual application of lubricating oil. This method is not only time-consuming and laborious, but also difficult to apply evenly, affecting the maintenance effect and the service life of the seat.

[0005] In addition, in order to solve the above problems, some devices with lubrication and maintenance functions have been introduced in the existing technology. However, the structures of these devices are relatively simple and cannot flexibly adjust the oil output volume each time they are opened. This limitation makes the maintenance device unable to adjust the supply volume of lubricating oil according to the actual wear condition of the slide rail, resulting in either insufficient lubrication, affecting the maintenance effect, or excessive lubrication, causing waste of lubricating oil and even possible pollution of the seat and the vehicle interior environment.

The slope block 2 is arranged on one side of the push rod 4, the push rod 4 is connected to one side of the sealing plate 7, both ends of the spring 5 are respectively connected to the movable frame 8 and the matching plate 10, the flow blocking block 6 is arranged on the other side of the sealing plate 7, the sealing plate 7 is arranged in the fixed pipe 3, the outer side of the movable frame 8 is movably connected to the inner wall of the fixed pipe 3 through a thread, the fixed plate 9 is fixedly arranged on the inner side of the fixed pipe 3, an adjusting mechanism is arranged on the inner side of the fixed pipe 3, and the adjusting mechanism includes a connecting frame 11, a through groove 12, a control sleeve 13, a slider 14, a sliding groove 15, a threaded rod 16, a sliding frame 17, a rib groove 18, a connecting rod 19 and a rib block 20. The through groove 12 is opened on one side of the sliding frame 17, the control sleeve 13 is connected to the connecting rod 19 through the connecting frame 11, the slider 14 is arranged on the outer side of the sliding frame 17, the sliding groove 15 is opened on the inner side of the fixed pipe 3, the threaded rod 16 is connected to one side of the matching plate 10, and the sliding frame 17 is movably connected to the outer side of the threaded rod 16 through a thread. The rib groove 18 is opened on the inner side of the movable frame 8, the connecting rod 19 is connected to one side of the rib block 20, and the rib block 20 is connected to the other side of the matching plate 10.

[0034] Bellows 21 are symmetrically arranged on both sides of the control sleeve 13.

[0035] A sealing block 22 is arranged on one side of the sealing plate 7, and a sealing groove 23 is correspondingly opened on one side of the fixed plate 9. The sealing block 22 is adapted to the sealing groove 23.

[0036] In this embodiment, when the device needs to be used, the mechanism of the maintenance device needs to be adjusted according to the actual requirements and the existing state. First, directly rotate the control sleeve 13. The control sleeve 13 drives the connecting rod 19 to rotate through the connecting frame 11. Then, the connecting rod 19 drives the prism block 20 and the matching plate 10 to rotate, thereby driving the threaded rod 16 to rotate. Since the inner wall of the sliding frame 17 is movably connected to the threaded rod 16 through threads, and the slider 14 and the chute 15 limit the sliding frame 17, then the sliding frame 17 will drive the slider 14 to slide along the chute 15, causing the distance between the sliding frame 17 and the sealing plate 7 to change, and further causing the gap between the through slot 12 and each flow-blocking block 6 to change. Even the maintenance device can be closed by the sliding frame 17, so that no lubricating oil will leak out when the maintenance device is opened. After adjustment, stop rotating the control sleeve 13. It is also possible to pull up the control sleeve 13. The control sleeve 13 will drive the bellows 21 provided on one side to extend and compress the bellows 21 provided on the other side. Then, the control sleeve 13 will drive the connecting rod 19 to slide through the connecting frame 11, causing the connecting rod 19 to drive the prism block 20 to move. Then, the prism block 20 will enter the prism groove 18. Then, rotate the control sleeve 13. The control sleeve 13 drives the connecting rod 19 to rotate through the connecting frame 11, and then drives the prism block 20 to rotate. Then, the prism block 20 will drive the movable frame 8 to rotate through the prism groove 18. Since the outer wall of the movable frame 8 and the inner wall of the fixed tube 3 are movably connected through threads, then the movable frame 8 will slide along the prism block 20, causing the distance between the movable frame 8 and the matching plate 10 to change, and then the gap of the spring 5 to change, thereby changing the reset force and reset speed of the sealing plate 7, and further changing the oil output of the lubricating oil. Then, when one end of the ejector rod 4 abuts against the slope block 2, the ejector rod 4 will drive the sealing plate 7 to move, causing the sealing plate 7 to drive the sealing block 22 to disengage from the sealing groove 23. Then, the sealing plate 7 drives the threaded rod 16 and the sliding frame 17 to move. Then, the threaded rod 16 drives the matching plate 10 to move, causing the matching plate 10 and the movable frame 8 to cooperate to squeeze the spring 5. Then, the lubricating oil in the external oil storage bottle will pass through the bellows 21, the control sleeve 13, the movable frame 8, the through slot 12, and the gap between the sealing plate 7 and the fixed block, and then flow into the slide rail 31 to achieve lubrication of the slide rail 31 and the slide seat 32. When the ejector rod 4 no longer contacts the slope block 2, the spring 5 pushes the matching plate 10 to reset, causing the matching plate 10 to drive the threaded rod 16 and the sealing plate 7 to reset, and causing the sealing plate 7 to drive the sealing block 22 to re-insert into the sealing groove 23 to achieve re-sealing of the fixed tube 3.

[0037] Please refer to Figures 1-5, as an embodiment of the movable device: The movable device includes a mounting base 24, a movable slot 25, a rotating shaft 26, a movable plate 27, a pushing spring 28, a positioning rod 29, a positioning slot 30, a slide rail 31 and a sliding seat 32. The mounting base 24 is detachably installed on both sides of the slide rail 31. The sliding seat 32 is detachably arranged below the mounting base 24, and the sliding seat 32 is slidably arranged in the slide rail 31. The movable slot 25 is opened on one side of the sliding seat 32. The rotating shaft 26 is installed in the movable slot 25. The movable plate 27 and the rotating shaft 26 are movably connected. The pushing spring 28 is movably arranged on one side of the movable plate 27. The positioning rod 29 is connected to the other side of the movable plate 27. The positioning slot 30 is opened at the bottom end of the slide rail 31.

[0038] A limiting rod 33 is movably arranged inside the mounting base 24. A wrench 34 is arranged on one side of the limiting rod 33. The wrench 34 is fixedly connected to one side of the limiting rod 33.

[0039] A backrest 35 is movably arranged on one side of the seat 1. A headrest 36 is arranged on the backrest 35.

[0040] Rotating frames 37 are symmetrically arranged on both sides of the backrest 35. A gear 38 is arranged on one side of the rotating frame 37. A worm 39 is arranged on one side of the gear 38. Tapered gears 40 are arranged at one end of the worm 39 and one side of the mounting base 24 respectively, and the two tapered gears 40 are meshed with each other.

[0041] A knob 41 is arranged at one end of the tapered gear 40 installed on one side of the mounting base 24.

[0042] More specifically, when it is necessary to adjust the angle of the backrest 35, rotate the knob 41. The knob 41 drives the corresponding tapered gear 40 to rotate. Then the tapered gear 40 drives the tapered gear 40 arranged on the other side to rotate. Then the tapered gear 40 here drives the worm 39 to rotate. The worm 39 drives the gear 38 meshed with it to rotate. Then the gear 38 drives the rotating frame 37 to move, so that the rotating frame 37 drives the angle of the backrest 35 to change. After adjusting to the appropriate angle, stop rotating the knob 41. When it is necessary to adjust the longitudinal position of the seat 1, first pull up the wrench 34. The wrench 34 drives the limiting rod 33 to rotate, and the other end of the wrench 34 presses down on one side of the movable plate 27. Due to the setting of the rotating shaft 26, the other side of the movable plate 27 will lift up. Then the movable plate 27 squeezes the pushing spring 28 arranged on one side. Then the movable plate 27 drives the positioning rod 29 arranged on the other side to move, so that the positioning rod 29 disengages from the positioning slot 30. Then push the seat 1. The seat 1 drives the sliding seat 32 to slide along the slide rail 31 through the mounting base 24. After adjusting to the appropriate position, release the wrench 34. The pushing spring 28 pushes the movable plate 27 to reset. Then the movable plate 27 drives the positioning rod 29 arranged on the other side to insert into the positioning slot 30 for positioning to prevent the seat 1 from sliding continuously. Then the other side of the movable plate 27 pushes the wrench 34 to reset.

[0043] In summary, when the overall device is in use or operation: when the device needs to be used, first adjust the mechanism of the maintenance device according to the actual requirements and the existing state. First, directly rotate the control sleeve 13. The control sleeve 13 drives the connecting rod 19 to rotate through the connecting frame 11. Then, the connecting rod 19 drives the prism block 20 and the matching plate 10 to rotate, thereby driving the threaded rod 16 to rotate. Since the inner wall of the sliding frame 17 is movably connected to the threaded rod 16 through threads, and the slider 14 and the chute 15 limit the sliding frame 17, then the sliding frame 17 drives the slider 14 to slide along the chute 15, causing the distance between the sliding frame 17 and the sealing plate 7 to change, and further causing the gap between the through slot 12 and each flow-blocking block 6 to change. Even the maintenance device can be closed by the sliding frame 17, so that no lubricating oil leaks out when the maintenance device is opened. After adjustment, stop rotating the control sleeve 13. It is also possible to pull up the control sleeve 13. The control sleeve 13 will drive the bellows 21 provided on one side to extend and compress the bellows 21 provided on the other side. Then, the control sleeve 13 will drive the connecting rod 19 to slide through the connecting frame 11, so that the connecting rod 19 drives the prism block 20 to move. Then, the prism block 20 will enter the prism groove 18. Then, rotate the control sleeve 13. The control sleeve 13 drives the connecting rod 19 to rotate through the connecting frame 11, and then drives the prism block 20 to rotate. Then, the prism block 20 drives the movable frame 8 to rotate through the prism groove 18. Since the outer wall of the movable frame 8 and the inner wall of the fixed tube 3 are movably connected through threads, then the movable frame 8 slides along the prism block 20, causing the distance between the movable frame 8 and the matching plate 10 to change, and then the gap of the spring 5 to change, thereby changing the reset force and reset speed of the sealing plate 7, and further changing the oil output of the lubricating oil. Then, when one end of the ejector rod 4 abuts against the slope block 2, the ejector rod 4 drives the sealing plate 7 to move, causing the sealing plate 7 to drive the sealing block 22 to disengage from the sealing groove 23. Then, the sealing plate 7 drives the threaded rod 16 and the sliding frame 17 to move. Then, the threaded rod 16 drives the matching plate 10 to move, causing the matching plate 10 and the movable frame 8 to cooperate to squeeze the spring 5. Then, the lubricating oil in the external oil storage bottle passes through the bellows 21, the control sleeve 13, the movable frame 8, the through slot 12, and the gap between the sealing plate 7 and the fixed block, and then flows into the slide rail 31 to achieve lubrication of the slide rail 31 and the slide seat 32. When the ejector rod 4 no longer contacts the slope block 2, the spring 5 pushes the matching plate 10 to reset, causing the matching plate 10 to drive the threaded rod 16 and the sealing plate 7 to reset, and causing the sealing plate 7 to drive the sealing block 22 to re-insert into the sealing groove 23 to achieve re-sealing of the fixed tube 3.

[0044] When it is necessary to adjust the angle of the backrest 35, turn the knob 41. The knob 41 drives the corresponding bevel gear 40 to rotate. Then the bevel gear 40 drives the bevel gear 40 arranged on the other side to rotate. Then the rotation of the bevel gear 40 here drives the worm 39 to rotate. The worm 39 drives the engaged gear 38 to rotate. Then the gear 38 drives the rotating frame 37 to move, causing the angle of the rotating frame 37 to drive the backrest 35 to change. After adjusting to the appropriate angle, stop turning the knob 41. When it is necessary to adjust the longitudinal position of the seat 1, first pull up the wrench 34. The wrench 34 drives the limit rod 33 to rotate, and the other end of the wrench 34 presses down on one side of the movable plate 27. Due to the setting of the rotating shaft 26, the other side of the movable plate 27 will lift upward. Then the movable plate 27 squeezes the push spring 28 arranged on one side. Then the movable plate 27 drives the positioning rod 29 arranged on the other side to move, causing the positioning rod 29 to disengage from the positioning groove 30. Then push the seat 1. The seat 1 drives the sliding seat 32 to slide along the slide rail 31 through the mounting seat 24. After adjusting to the appropriate position, release the wrench 34. The push spring 28 pushes the movable plate 27 to reset. Then the movable plate 27 drives the positioning rod 29 arranged on the other side to insert into the positioning groove 30 for positioning to prevent the seat 1 from sliding continuously. Then the other side of the movable plate 27 pushes the wrench 34 to reset.
