With the continuous improvement of living standards, cars have become the main means of transportation for people to travel. In order to reduce the fatigue caused by long-term driving, car seats are usually equipped with lumbar supports. At present, car seats on the market are practical The lumbar support structure has two forms: manual and electric. Manual lumbar support has been widely used in car seat adjustment systems. Due to its insufficient adjustment, the accuracy of adjustment, and prone to failure, it can no longer meet people’s needs for comfort and Speed; electricity The lumbar support is more and more popular with consumers for its fast and flexible, good adjustment accuracy, and not easy to malfunction.
However, the above-mentioned electric lumbar support products still have certain shortcomings and deficiencies, which are specifically shown in: ①, The material used in the drive structure and the internal planetary gear is unreasonable, which is easy to damage and cause mechanical failure, which is not convenient for installation and maintenance; ② The supporting pallet has a complicated structure, and the structure is not compact enough, and the adjustment is not flexible.
Lumbar support adjustment can be divided into electric and manual methods. Through the continuous adjustment of the button or the different gears, if the waist is always in the “nested” position during driving, it will affect the blood circulation of the waist, and it will also cause discomfort to people suffering from waist diseases. Lumbar support can be improved. The waist curve, the waist bends inward on a seat without support function. If it cannot be supported, fatigue will appear over time. Prolonged waist fatigue will cause certain safety hazards to drive. The lumbar support function can be supported by the lumbar support. The adjustment enables the driver and passengers to keep the waist in a very comfortable state and alleviates a series of problems caused by the waist curled up in the seat.
The Working Principle of the ELS
The drive includes a motor, a worm, a housing, a worm gear, a small shaft, a planetary gear ring, a planetary gear, a wire wheel, and an upper cover. The motor connected with the worm is set in a mounting hole on one side of the housing through a copper sleeve, and the small shaft is set in the housing The turbine is sleeved on the small shaft and inStalled on the bottom of the casing. The planetary gear ring with teeth on the outer ring meshes and fixes with the casing and is sleeved on the worm gear. The three planetary gears are set on the three protrusions below the wire wheel. On the shaft, a wire wheel with a wire-pull hole is arRanged on the planetary gear ring, three planetary gears mesh with the inner teeth of the planetary gear ring, and the upper cover is mounted on the shell through a screw buckle.
How Kinmore makes improvement
Driven by Kinmore motor, it can efficiently adjust the position of the car seat in eight directions, so that the seat fits perfectly with the human body and provides strong lumbar support. During this period, the powerful power of our motor combined with high Torque can make the seat adjustment simple and efficient, in one step.
For the electric lumbar support, we recommend using this DC motor (RC-370SH-11580U), because it has the characteristics of low noise, high Torque, high performance, and long life. Of course, we can also according to the performance requirements of customers to provide a comprehensive evaluation of the motor and customize it.
