Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle accessories, and in particular relates to an electric long slide rail device for a vehicle seat with a quick response function. Background Art

[0002] With the improvement of people's living standards and the continuous advancement of science and technology, the automobile industry has developed by leaps and bounds, and people's requirements for vehicle riding comfort have become increasingly higher. As one of the important components of a car, a superior seat design can bring a comfortable riding experience to passengers. Different types of vehicles have different requirements for seats. For some small family cars with small space and low comfort requirements, most of them use two front seats that can move forward and backward and adjust the seat back angle, and a fixed seat in the back row; for some commercial vehicles with large space and high comfort requirements, they will have functions such as backrest adjustment, forward and backward movement, vertical lifting and even seat rotation, so that passengers can enter and ride comfortably; and with the continuous improvement of the intelligence level of the automobile industry and the rapid development of unmanned driving technology, the requirements for the forward and backward movement distance of vehicle seats are getting higher and higher, that is, the forward and backward movement distance of vehicle seats is required to be longer, so as to make the space in the car more flexible and changeable. The length of the slide rail mechanism of this seat product is generally more than one meter, so as to further improve the riding comfort experience and facilitate passenger activities, thereby greatly improving user comfort and space utilization. Therefore, this slide rail device that can realize the long-distance forward and backward movement of vehicle seats, which originally only existed in some large luxury commercial vehicles, has become more and more the focus of current intelligent car research and development.

[0003] In the published Chinese patent documents, relevant technical information about the electric rail device of the vehicle seat can be seen, and some of them are CN113147527B (electric long slide rail for automobile seat and its transmission method), CN216331569U (electric long slide rail that helps to improve transmission noise), CN112537231A (automatic slide rail device for automobile seat), etc. A typical example is a slide rail driving structure, which includes a left slide rail, a right slide rail, a mounting frame and a driving mechanism, wherein the left and right slide rails extend in parallel and respectively include an upper rail and a lower rail, and the two ends of the mounting frame are respectively mounted on the upper rails of the left and right slide rails, and the driving mechanism is installed through the mounting frame and has and only has one motor to drive the upper rails of the left and right slide rails to move synchronously relative to the lower rail, and the driving mechanism includes a primary transmission and a secondary transmission, the primary transmission is connected to the motor through a first flexible shaft, and the secondary transmission is connected to the primary transmission through a second flexible shaft, and the lead screws of the left and right slide rails are connected to the secondary transmission to transmit the output torque of the motor to the lead screws through the two-stage transmission. However, the slide rail structure still has the common drawbacks of the slide rail structure in the prior art: first, the overall structure is complex, the number of components is large, and it occupies a lot of space. There is a risk of mutual interference among the components, which increases the risk of operational safety; in the prior art, the upper rail mostly moves directly inside the lower rail during movement, and there are no corresponding components on the upper rail for guiding and supporting its movement, which makes the upper rail prone to shaking and stalling during movement, especially during startup, and cannot guarantee the smoothness of operation. In addition, the upper rail vibrates when sliding, accompanied by abnormal sounds and noises, and cannot ensure the smoothness of sliding operation, which greatly reduces the user experience; in addition, the existing vehicle seat slide rail structure generally has the problem of a relatively complex transmission structure, and the drive motor and transmission The installation structure between units is relatively complex, with a large number of components, and the drive motors are mostly installed directly at the bottom of the vehicle seat. The installation structure is complicated, time-consuming and labor-intensive. Finally, most of the existing transmission mechanisms have a slow output speed, and there is a lag between the control command and the final transmission. However, the current electric long slide rail devices require high-speed operation and fast response characteristics to meet the needs of drivers and passengers. This transmission mechanism with a slow output speed will result in a poor user experience, and will cause the motor to have high power and energy consumption when driven, resulting in high production costs, poor transmission efficiency and poor mechanical properties, which will reduce the stability of operation and often easily lead to inconsistent operation synchronization. At the same time, the equipment failure rate is high and the maintenance workload is large, which cannot meet the current development needs of electric long slide rails for vehicle seats.

[0004] In view of the above situation, it is necessary to reasonably improve the existing vehicle seat slide rail structure. For this reason, the applicant has made a useful design, and the technical solution to be introduced below is produced under this background. Utility Model Content
