Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, specifically to an automatically lubricated sliding track connection device for automotive seats. Background Technology

[0002] A car seat is the seat you sit on while riding in a car. Based on parts, they can be roughly divided into: front seats (headrest, backrest, seat cushion, armrest); and rear seats (headrest, backrest, seat cushion, side bolsters, armrest). Car seats can also be categorized by shape (split seats, bench seats); by function (fixed, removable, adjustable); and by passenger capacity (single, double, multi-seater). Based on performance, car seats have evolved from the earliest fixed seats to multi-functional power-adjustable seats, including air-cushioned seats, electric seats, stereo seats, recovery seats, and electronically adjustable seats. They can also be categorized by material (leather seats, cloth seats, etc.) and there are special seats for specific users, such as child seats and racing seats.

[0003] Car seats slide on tracks via bottom rollers. Over time, the rollers wear down, increasing friction with the tracks and causing the seats to jam during adjustment, affecting usability. Furthermore, the tracks don't automatically inject lubricant, requiring disassembly and reassembly for lubrication when significant friction occurs, which is inconvenient. Therefore, to address these shortcomings, this invention provides an automatically lubricated car seat track connection device. Summary of the Invention

A squeezing plate is fixedly connected to the end of the squeezing rod that extends to the top of the movable groove. An oil-absorbing sponge is placed on the top of the squeezing plate. An oil inlet groove is provided inside the base and on the opposite side of the two movable grooves. A sealing cap is threaded to the top of the oil inlet groove. A solenoid valve is fixedly connected inside the oil inlet groove.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-4 This invention provides a technical solution: an automatic lubrication car seat slide rail connection device, which can automatically inject lubricating oil into the top of the slide rail 7 when wear occurs between the pulley 14 and the slide rail 7 to achieve a lubrication effect without manual addition, which is convenient and labor-saving. At the same time, excess oil is recycled into the oil-absorbing sponge 56 for reuse, which meets the requirements of energy conservation and environmental protection. It includes a base 1 and a buffer pad 2 fixedly connected to the bottom of the base 1. The base 1 has an movable groove 3 inside, and fixed grooves 4 are opened on both sides of the top of the base 1. The base 1 is equipped with a lubrication mechanism 5.

[0019] When wear occurs between the pulley 14 and the slide rail 7, lubricating oil can be automatically injected into the top of the slide rail 7 to achieve a lubrication effect without manual addition, which is convenient and labor-saving. At the same time, excess oil is collected into the oil-absorbing sponge 56 for reuse, which meets the requirements of energy conservation and environmental protection.

[0020] Specifically, the lubrication mechanism 5 includes an electric push rod 51. A through groove 52 is provided inside the base 1 and at the top of the fixed groove 4. The top end of the electric push rod 51 is fixedly connected to the bottom of the inner wall of the through groove 52. A push plate 53 that penetrates into the fixed groove 4 is fixedly connected to the extended end of the electric push rod 51. Both sides of the top of the push plate 53 are fixedly connected to a squeezing rod 54. The top end of the squeezing rod 54 penetrates the movable groove 3 and extends to the top of the movable groove 3. A squeezing plate 55 is fixedly connected to the end of the squeezing rod 54 that extends to the top of the movable groove 3. An oil-absorbing sponge 56 is placed on the top of the squeezing plate 55. An oil inlet groove 57 is provided inside the base 1 and on the opposite side of the two movable grooves 3. A sealing cap 58 is threadedly connected to the top of the oil inlet groove 57. A solenoid valve 59 is fixedly connected inside the oil inlet groove 57. When the solenoid valve 59 is closed, the oil-absorbing sponge 56 will not overflow to the outside through the oil inlet groove 57 when the squeezing plate 55 squeezes upward.

[0021] Specifically, protective plates 6 are fixedly connected to both sides of the inner wall of the movable groove 3, and a slide rail 7 is fixedly connected between the opposite sides of the two protective plates 6.

[0022] Specifically, the slide 7 has an oil outlet hole inside, and the top of the oil-absorbing sponge 56 is in contact with the bottom of the slide 7.

[0023] Specifically, both sides of the extrusion plate 55 are in contact with the inner wall of the movable groove 3 through pistons, and the opposite sides of the two protective plates 6 are fixedly connected with limit blocks 8.

[0024] Specifically, the bottom of the limiting block 8 is connected to the vertical tube 9, and the bottom end of the vertical tube 9 passes through the slide rail 7 and extends to the bottom of the slide rail 7.

[0025] Specifically, the protective plate 6 has an internal cavity, and sound-absorbing cotton 10 is fixedly connected inside the cavity. A support plate 11 is slidably connected between the two limiting blocks 8 on opposite sides. Both sides of the top of the support plate 11 are fixedly connected to connecting plates 13 by spring rods 12. Both sides of the bottom of the support plate 11 are fixedly connected to pulleys 14, and the bottom of the pulleys 14 is in contact with the top of the slide 7. Preferably, the buffer pad 2 is made of rubber and has a thickness of at least 5 mm.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] In use, lubricating oil is injected into the movable groove 3 through the oil inlet groove 57 beforehand. At this time, the lubricating oil is absorbed and stored by the oil-absorbing sponge 56. When it is necessary to lubricate the top of the slide 7, the external switch is activated, which causes the extended end of the electric push rod 51 to drive the push plate 53 to move upward. The push plate 53 then drives the extrusion rod 54 to move upward. At this time, the extrusion plate 55 drives the extrusion rod 54 to extrude the oil-absorbing sponge 56, thereby squeezing out the lubricating oil stored inside the oil-absorbing sponge 56. The lubricating oil seeps out to the top of the slide 7 through the oil outlet hole on the surface of the slide 7. The oil on the surface of the slide 7 comes into contact with the pulley 14 to perform lubrication. At the same time, some lubricating oil enters the inner wall of the limit block 8 through the vertical pipe 9 to achieve lubrication when the support plate 11 moves. The excess oil generated during lubrication is returned to the oil-absorbing sponge 56 through the oil outlet hole. This cycle can be repeated.
