TECHNICAL FIELD
[0001] The present application relates to the technical field of automobile seat slide rail, and particularly to a seat bottom long slide rail with opening and closing locking device and method. BACKGROUND
[0002] The automobile seat slide rail is a key component connecting the seat and the vehicle floor, and its core function is to realize the position adjustment of the seat in the longitudinal direction (front and rear direction) of the vehicle to meet the seating needs of passengers of different body types and ensure that the driver can find the best driving posture. In order to ensure driving safety, the seat must be firmly locked in a certain position of the slide rail after adjustment, to prevent accidental movement during vehicle acceleration, braking or collision. In the event of a vehicle collision, especially a rear-end collision, a huge inertial force will be transmitted to the slide rail system through the seat. If the engagement depth between the locking pin and the locking hole is insufficient, or there is a manufacturing tolerance or excessive gap due to wear, the huge impact load may cause the locking pin to "jump teeth" or deform and come out of the locking hole, causing the seat to suddenly move backward. This can seriously weaken the restraining effect of the seat on the passenger and increase the risk of injury to the passenger in a secondary collision.

S3: The support easing frame (15) slides on the position of the limiting bottom rail (14) and can be moved according to the position of the car seat (6). A support easing spring (16) is set between the car seat (6) and the support easing frame (15) to achieve easing support. The support connecting plate (17) is fixedly connected to the bottom surface of the car seat (6). The damping telescopic rod (21) is controlled to extend and retract through the damper (20) to achieve support on the bottom surface of the support connecting plate (17). S4: The electrical connection between the heating controller (26) and the heating back pad (24) is achieved through the heating resistance wire (25) inside the heating back pad (24), which heats the back of the person in the vehicle seat (6) and increases the comfort of contact. S5: The fan power box (33) controls the power chassis (31) inside the air blower compartment (29) to rotate and blow air. The airflow passes through the air blower cooling fan (32) to blow air onto the people in the vehicle seat (6), further increasing the comfort of the device when the weather is hot.
