Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive seat technology, and more specifically, to a versatile automotive seat linkage. Background Technology
[0002] The car seat linkage is a key transmission component in the seat adjustment mechanism. It is mainly used to connect the handle, motor, slide rail or backrest adjustment mechanism, and transmit the control force or driving force to various actuators of the seat to realize functions such as seat forward and backward movement, backrest angle adjustment, and seat cushion height adjustment. It is usually required to have high strength, good rigidity, fatigue resistance, and good assembly precision and corrosion resistance to ensure smooth, reliable seat adjustment and service life.
[0003] While existing automotive seat linkages can be used normally, they still have many drawbacks in actual use. For example, existing automotive seat linkages are not very versatile. Due to the different interior spaces of large and small cars, the seat sizes also differ, and the automotive seat linkages used are all different sizes. Therefore, it is necessary to design automotive seat linkages of various sizes, which is very inconvenient. Summary of the Invention
[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a highly versatile automotive seat linkage. This linkage comprises an adjustment mechanism, a front adjustment linkage mechanism, and a rear adjustment linkage mechanism. The device can be adjusted according to actual needs. Rotating either of the two turning discs causes the two adjusting screws to rotate, thereby bringing the first and second linkage support plates closer together or further apart. By providing guide rods and guide holes, with both the guide rod and guide hole having a quincunx cross-sectional shape, movement of the first and second linkage support plates causes the guide rod to move within the guide hole. The quincunx-shaped guide rod and guide hole, in conjunction, improve anti-rotation capability while ensuring guiding accuracy. The improved positioning stability makes the movement process smoother and less prone to swaying. Due to the multi-sided force and large contact constraint of the plum blossom contour, it can also improve the force distribution, reduce the risk of local wear and jamming, and improve durability and consistency of repeated positioning. In addition, the plum blossom structure, to a certain extent, balances load-bearing capacity and structural compactness, which can realize the miniaturized design of the structure. This is conducive to assembly alignment and reliable operation in long-term use. This allows the width of the invention to be adjusted according to the actual needs of the scenario, thereby adapting to different types of vehicles. This makes the invention more versatile and avoids the problem of designing different sized car seat linkages according to different vehicle models. It also reduces the research and development design costs and is very convenient, thus solving the problems mentioned in the background art.

The quincunx-shaped guide rod and the guide hole cooperate to improve the anti-rotation capability and positioning stability while ensuring guiding accuracy, making the movement process smoother and less prone to swaying. Due to the quincunx contour having multi-sided force and large contact constraints, it can also improve the force distribution, reduce the risk of local wear and jamming, and improve durability and repeatability consistency. In addition, the quincunx structure, to a certain extent, balances load-bearing capacity and structural compactness, enabling miniaturized structural design, which is beneficial for assembly alignment and reliable operation during long-term use.
[0008] In a preferred embodiment, the two threaded sleeves are respectively welded to the middle of the first connecting rod support plate and the middle of the second connecting rod support plate.
[0009] In a preferred embodiment, the cross-sectional shape of the guide rod is set to a quincunx shape, and the cross-sectional shape of the guide hole is set to a quincunx shape.
[0010] In a preferred embodiment, the guide hole matches the shape of the guide rod at the corresponding position, and the guide rod is disposed inside the guide hole at the corresponding position.
[0011] In a preferred embodiment, the guide rod is slidably connected to the sleeve rod at the corresponding position via a guide hole.
[0012] In a preferred embodiment, the end rod is fixedly connected to one of the first and second connecting rod support plates via a rod seat.
[0013] In a preferred embodiment, the threaded sleeve is threadedly connected to the adjusting screw at the corresponding position, and the two adjusting screws have opposite thread directions.
[0014] In a preferred embodiment, the first and second connecting rod support plates are made of carbon steel.
[0015] A method for using a versatile automotive seat linkage, comprising the versatile automotive seat linkage described in any one of the above-mentioned embodiments and the following steps:
[0016] S1: Adjust the device according to actual needs. Rotate either of the two turning discs. The turning disc drives the two adjusting screws to rotate, so that the first connecting rod support plate and the second connecting rod support plate move closer to each other or further away from each other.
[0017] S2: By setting a guide rod and a guide hole, and setting the cross-sectional shape of the guide rod to be plum blossom-shaped and the cross-sectional shape of the guide hole to be plum blossom-shaped, the movement of the first connecting rod support plate and the second connecting rod support plate causes the guide rod to move in the guide hole, thereby achieving guide and limit;
[0018] S3: After adjustment, stop rotating the rotating disc.
[0019] The technical effects and advantages of this invention are as follows:
[0020] This invention incorporates an adjustment mechanism, a front adjustment linkage mechanism, and a rear adjustment linkage mechanism. The device can be adjusted according to actual needs. Rotating either of the two turning discs causes the two adjusting screws to rotate, thus bringing the first and second linkage support plates closer together or further apart.

The first link support plate 1 is disposed on one side of the second link support plate 2. Grooves 3 are provided on both the side of the first link support plate 1 away from the second link support plate 2 and the side of the second link support plate 2 away from the first link support plate 1.

[0041] S2: By setting guide rod 605 and guide hole 603, and setting the cross-sectional shape of guide rod 605 to plum blossom shape and the cross-sectional shape of guide hole 603 to plum blossom shape, the movement of first connecting rod support plate 1 and second connecting rod support plate 2 causes guide rod 605 to move in guide hole 603, thereby achieving guide limit;
