Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to an eccentric block for adjusting automotive seat slide rails. Background Technology

[0002] In the development of automotive seat technology, seat height adjustment has played a crucial role in improving driving comfort and safety. However, as consumers' demands for the automotive riding experience have increased, the limitations of existing seat height adjustment technologies have become increasingly apparent. Traditional automotive seat height adjustment mechanisms mostly use relatively simple mechanical structures, such as the use of screws and nuts or simple linkage mechanisms to raise and lower the seat. However, these traditional methods cannot meet the high standards of modern automotive manufacturing in terms of adjustment precision. In actual use, due to limitations in manufacturing processes and long-term wear, jamming often occurs during adjustment, causing the seat to be unable to smoothly stay at the required precise height position, which brings great inconvenience to users. During vehicle operation, especially under complex road conditions, such as when driving on bumpy roads, going up and down slopes, or when the vehicle body posture changes at high speeds, the stability of the seat height is severely challenged. Existing height adjustment devices often cannot effectively suppress the up and down bouncing of the seat caused by vehicle vibrations. This not only affects the riding comfort of passengers but may also distract the driver's attention, posing a potential threat to driving safety.

[0003] Furthermore, with the diversified design of automotive interior spaces and the in-depth application of ergonomics, there are higher expectations for the range and flexibility of seat height adjustment. Traditional adjustment mechanisms, due to inherent defects in their structural design, have limited adjustment ranges and cannot meet the personalized seat height needs of drivers and passengers of different heights. For example, taller drivers may need to raise their seats to a higher position to obtain better visibility and legroom, but traditional seat height adjustment devices may not be able to reach their ideal height, thus affecting the driving experience. Moreover, existing seat height adjustment operations are usually cumbersome and require considerable force, which can be very strenuous for users with less strength, especially when frequently adjusting seat height. At the same time, the noise problem during the adjustment process cannot be ignored; excessive noise will reduce the quietness of the car interior and affect the driving and riding experience. Utility Model Content

[0004] The purpose of this utility model is to provide an eccentric block for adjusting the slide rail of an automobile seat, so as to solve the problems of poor stability, low precision and inconvenient operation of the traditional automobile seat slide rail adjustment mechanism mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an eccentric block for adjusting the slide rail of an automobile seat, comprising a central disc, an eccentric disc fixedly disposed on one outer surface of the central disc, and a contact seat fixedly disposed on one outer surface of the eccentric disc, and the outer surfaces of the eccentric disc and the contact seat are both penetrated by clearance holes, and the inner surface of the clearance hole located inside the eccentric disc is provided with an anti-slip groove and an anti-fooling groove.

[0006] Preferably, a central shaft is provided on one side of the central disk, and a limit baffle is fixedly provided on the outer surface of the end of the central shaft facing the central disk.

[0007] By adopting the above technical solution, the relative axial displacement between the central shaft and the central plate can be effectively limited by the limiting baffle, preventing the central shaft from coming off during use, ensuring the integrity and stability of the overall structure of the eccentric block, making the adjustment process more reliable and safe, ensuring that the seat adjustment mechanism can operate continuously and stably, and providing a basic guarantee for long-term precise seat height adjustment.

[0008] Preferably, a locking block is fixedly provided on the outer surface of the limiting baffle facing the central disk, and the clearance hole is penetrated by a locking bolt.

[0009] Using the above technical solution, the locking bolt is stably connected to the central shaft through one end of the through-hole.

[0010] Preferably, the central disk and the eccentric disk are eccentrically designed, and the central disk, the contact seat, and the clearance hole are concentrically arranged.

[0011] By adopting the above technical solution, the eccentric design enables the eccentric disk to produce vertical displacement changes when the central shaft rotates, thereby achieving precise adjustment of seat height and meeting the personalized needs of different users for seat height. The concentric arrangement of the central disk, contact seat, and clearance hole ensures uniform force transmission, reduces additional stress and wear caused by structural asymmetry, improves the working efficiency and service life of the eccentric block, and ensures that the stability and accuracy of seat height adjustment will not be affected during long-term use.

[0012] Preferably, the anti-slip grooves are evenly spaced on the inner surface of the clearance hole, and the anti-slip grooves are arc-shaped, as are the anti-fouling grooves.

[0013] By adopting the above technical solution, the equidistant arc design of the anti-slip groove increases the friction between the locking block and the inner wall of the clearance hole, effectively preventing slippage between the central shaft and the eccentric plate during adjustment, ensuring stable torque transmission, and making seat height adjustment more precise. The arc design of the anti-misalignment groove plays a role in preventing incorrect installation, avoiding the eccentric block from malfunctioning due to misoperation during installation or maintenance, improving assembly efficiency and operational accuracy, reducing the risk of failure caused by human factors, and ensuring the reliability and stability of the seat adjustment system.

[0014] Preferably, the central shaft and the locking bolt are threaded together, and one end of the locking bolt is in contact with the outer surface of the contact seat.

[0015] By adopting the above technical solution, the threaded connection method enables the locking bolt to generate a stable clamping force on the contact seat during the tightening process, which tightly fits the center plate and the limit baffle, preventing them from loosening due to vibration during vehicle operation and ensuring the stability of the seat height. At the same time, this connection method is easy to install and disassemble, which facilitates later maintenance and repair work, reduces maintenance costs and time, and improves the maintainability and practicality of the entire seat adjustment system.

[0016] Preferably, the central shaft is installed by engaging with the eccentric disc via a locking block, and the shape of the outer surface of the locking block matches the shape of the inner surface of the anti-slip groove and the anti-fouling groove.

[0017] By adopting the above technical solution, the snap-fit ​​installation method ensures the connection accuracy and stability between the central shaft and the eccentric disk, avoids relative displacement between the two during operation, and ensures the accuracy of adjustment.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the eccentric block for adjusting the car seat slide rail:

[0019] 1. The eccentric design of the center disc and the eccentric disc enables more precise micro-adjustment when adjusting the seat height. By changing the rotation angle of the eccentric disc, the seat height can be precisely adjusted. This design breaks through the limitations of traditional seat height adjustment, greatly improving the sensitivity and accuracy of height adjustment, and meeting the diverse and personalized needs of different users for seat height. Whether it is a petite passenger or a tall driver, they can easily find the most comfortable seat height position, significantly improving the comfort and ergonomic experience of riding.

[0020] Furthermore, the rational design of the eccentric and central discs, along with the concentric arrangement of each component, optimizes the distribution and transmission path of force. During vehicle operation, when encountering complex road conditions such as bumps, braking, and acceleration, this stable structure can effectively resist external forces from interfering with the seat height, ensuring that the seat height remains stable and reducing swaying and displacement. Even with long-term use, the close cooperation between the components can still maintain good stability, providing a solid and reliable guarantee for driving and riding safety.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution: an eccentric block for adjusting the slide rail of an automobile seat.

[0030] A central disk 1 is provided with an eccentric disk 2 fixedly installed on one side of the outer surface of the central disk 1, and a contact seat 3 is fixedly installed on one side of the outer surface of the eccentric disk 2. The outer surfaces of the eccentric disk 2 and the contact seat 3 are both penetrated by a clearance hole 4. An anti-slip groove 5 and an anti-fooling groove 6 are provided on the inner surface of one end of the clearance hole 4 inside the eccentric disk 2.

[0031] The center plate 1 and the eccentric plate 2 are eccentrically designed, and the center plate 1, the contact seat 3 and the clearance hole 4 are concentrically arranged.

[0032] Anti-slip grooves 5 are evenly spaced on the inner surface of the clearance hole 4, and the anti-slip grooves 5 are arc-shaped, as are the anti-fouling grooves 6.

[0033] A central shaft 7 is provided on one side of the central disk 1, and a limit baffle 8 is fixedly provided on the outer surface of the end of the central shaft 7 facing the central disk 1.

[0034] A locking block 9 is fixedly installed on the outer surface of the limiting baffle 8 facing the center plate 1, and the clearance hole 4 is penetrated by the locking bolt 10.

[0035] The central shaft 7 and the locking bolt 10 are threaded together, and one end of the locking bolt 10 is in contact with the outer surface of the contact seat 3.

[0036] The central shaft 7 is engaged with the eccentric disk 2 via the locking block 9, and the shape of the outer surface of the locking block 9 matches the shape of the inner surface of the anti-slip groove 5 and the anti-fouling groove 6.

[0037] Working principle: When the height of the car seat needs to be adjusted, the rotation of the central shaft 7 drives the eccentric disk 2, which is engaged with it, to rotate. The locking block 9 on the limiting baffle 8 at the end of the central shaft 7 facing the central disk 1 cooperates with the anti-slip groove 5 and anti-misalignment groove 6 in the clearance hole 4 of the eccentric disk 2 to ensure that the connection between the central shaft 7 and the eccentric disk 2 is stable and can accurately transmit torque, so that the eccentric disk 2 can rotate stably along the predetermined trajectory.

[0038] Since the center plate 1 and the eccentric plate 2 are eccentrically designed, the rotation of the eccentric plate 2 will change its positional relationship with the center plate 1, thereby causing the eccentric plate 2 to produce a vertical displacement change. The eccentric plate 2 is connected to other support structures of the seat, so its vertical displacement is directly converted into seat height adjustment.

[0039] The locking bolt 10 of the central shaft 7 and the through contact seat 3 are connected by threads to provide auxiliary fixation, prevent the central shaft 7 from rotating accidentally, and further enhance the stability after the seat height is adjusted. This ensures that the seat height will not change even if it is affected by external forces such as vibration and bumps during vehicle operation, providing a stable and comfortable riding experience for the driver and passengers.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
