Description

Technical Field

[0001] The invention relates to the technical field of front electric slide rails, and in particular to a front electric slide rail for intelligently adjusting a car seat. Background Art

[0002] In the existing automobile seat adjustment technology, the traditional manual adjustment method has problems such as cumbersome operation and low adjustment accuracy. At the same time, it is impossible to automatically adjust the seat posture according to the user's physical characteristics and driving habits. Therefore, in order to meet the user's requirements for comfort and convenience, the front electric slide rail of the car seat needs to be intelligently adjusted.

[0003] For example, the Chinese patent publication number CN115946583B discloses an electric slide rail with long-distance intelligent adjustment for automobile seats. The present invention collects manual adjustment curves for long-distance adjustment in daily adjustment processes, and then matches the manual adjustment curves with the corresponding users, thereby constructing basic quantitative data to match different users, and then filtering the data of the corresponding users to eliminate abnormal data, and at the same time extracting the manual adjustment curves and constructing and generating respectively the selected superior sets corresponding to the users, and generating multiple intelligent adjustment curves by accumulating a large number of selected superior sets of manual adjustment curves to correspond to different users, thereby constructing and generating a dynamic matching set, and when the user uses it again, the corresponding intelligent adjustment curve is automatically retrieved through the matching of recognition features and the movement of the sensing slide rail unit is automatically controlled to achieve intelligent space control to match the needs of different users.

[0004] For example, the Chinese patent publication number CN106985709A discloses an intelligent adjustment device, system and method for automobile seats, including: a positioning unit, which calculates and obtains the position information of each seat occupant according to the wireless signal of the wearable device and the received wireless signal; an identity recognition unit, which is used to obtain the user's identity information through the wearable device, and obtain the seat parameters corresponding to the user in the storage unit according to the recognized identity information and the obtained position information; a storage unit, which is used to memorize and store the identity information of several users and their corresponding seat parameters; an adjustment control unit, which adjusts the corresponding seat according to the seat parameters obtained by the identity recognition unit. The present invention realizes intelligent adjustment of automobile seats by utilizing wearable devices to intelligently identify the user's identity and the user's position in the car.

[0005] The above existing technologies still have the following problems: 1. Users who have driven the target vehicle and users who have not driven the target vehicle are not classified and discussed, and the front electric slide rail adjustment of the car seat is not classified and discussed according to these two driving conditions. For users who have driven the target vehicle, the cumbersome operation of users manually adjusting the seat is added. For users who have not driven the target vehicle, convenience cannot be provided for different users, which reduces the driving comfort of users.

[0006] 2. For users who have not driven the target vehicle, the front electric slide rail is not adjusted according to the user's physical characteristics before entering the vehicle, resulting in the seat position not meeting the user's comfort needs when entering the vehicle.

[0007] 3. For users who have not driven the target vehicle, if the front electric slide rail is not adjusted according to the angle between the user's foot and the pedal plane and the knee bending angle before driving, the user may face the problem of smooth pedal operation, which reduces the response speed and accuracy of the operation. At the same time, an inappropriate knee bending angle will limit the operational flexibility of the legs, thereby posing a threat to driving safety and reducing the user's driving safety.

Extract the appropriate moving distance of the front electric slide rail corresponding to the unit angle deviation from the database ; F3, if , it indicates that the front electric slide rail of the target vehicle does not need to be moved before the current driving by the inexperienced user; F4, if , then move the front electric slide rail of the target vehicle backward Distance, if , then move the front electric slide rail of the target vehicle forward distance; F5, if , then move the front electric slide rail of the target vehicle backward Distance, if , then move the front electric slide rail of the target vehicle forward distance; F6, if , then move the front electric slide rail of the target vehicle backward distance; F7, if , then move the front electric slide rail of the target vehicle forward distance; F8, if , the moving state of the front electric slide rail of the target vehicle before the current driving of the inexperienced user is judged according to the specific deviation degree.

10. The front electric slide rail for intelligent adjustment of a car seat according to claim 9, characterized in that: The specific process of judging the moving state of the front electric slide rail of the target vehicle before the current driving by the inexperienced user according to the specific deviation degree is as follows: G1. When , calculate the degree to which the angle between the instep and the pedal plane of an inexperienced user deviates from the ideal range during the current driving , , calculate the degree to which the knee bending angle of an inexperienced user deviates from the ideal range before the current driving , ,like , then move the front electric slide rail of the target vehicle backward Distance, if , then move the front electric slide rail of the target vehicle forward distance; G2, when ,like , then move the front electric slide rail of the target vehicle forward Distance, if , then move the front electric slide rail of the target vehicle backward distance.
