Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

Example 1

The embodiment provides a pre-crash processing method of a vehicle seat. As shown in fig. 1, the vehicle seat includes a side wing mechanism 21, a front lift mechanism 26, a rear lift mechanism 23, a slide rail mechanism (inner and outer slides 25, front and rear slides 24), a back rotation mechanism 22, and a vibrating mechanism (not shown) on a seat cushion. The invention adopts active safety measures to carry out pre-collision treatment aiming at the prior vehicle seat.

As shown in fig. 2, the pre-collision processing method of a vehicle seat of the present embodiment includes the steps of:

step 101, acquiring a primary alarm time, a secondary alarm time and a predicted collision time which are arranged in the order of time from morning to evening;

102, acquiring a current moment as a first current moment, judging whether the first current moment is between a predicted collision moment and a secondary alarm moment or equal to the secondary alarm moment, and if so, executing a secondary alarm processing step 103;

step 102 ', determining whether the first current time is between the second-level alarm time and the first-level alarm time or equal to the first-level alarm time, if yes, executing a first-level alarm processing step 103'.

The sequence of step 102 and step 102' is not limited, that is, either of them may be executed first. The processing manner may be selected as needed when the result of the two steps is negative, and this embodiment is not limited.

As shown in FIG. 3, the secondary alarm processing step 103 includes the steps of:

103-1, adjusting the side wing mechanisms to corresponding preset target positions;

and 103-2, respectively moving the adjusted lifting mechanism, the adjusted sliding rail mechanism and the adjusted backrest rotating mechanism to the corresponding preset target positions.

Each mechanism has a corresponding preset target position, which is a relatively safe area in the event of a collision, and the selected target position is the safest area in the embodiment. Wherein the specific location of the target location is not limiting of the invention.

And the secondary alarm moment is the moment when the vehicle with the vehicle seat collides with a preset second probability or is equal to the moment when the AEB system is started. The AEB system is the moment when the automobile system detects that the distance between the automobile system and the front automobile or the obstacle is less than the safe distance, and the driver does not press the brake pedal, and the automobile system starts automatic braking.

In other alternative embodiments, the sequence of steps 103-1 and 103-2 can be adjusted, and even the order of adjustment of the various mechanisms in step 103-2 can be adjusted, preferably by adjusting the backrest rotation mechanism and the slide rail mechanism first, and then adjusting the other mechanisms. That is, the present invention does not limit the adjustment sequence of each mechanism, and the way of adjusting the wing mechanism first and then adjusting the other mechanisms is only illustrated in this embodiment, and does not limit the protection scope of the present invention.

As shown in FIG. 4, the primary alarm processing step 103' includes the steps of:

and 103' -1, adjusting the side wing mechanism to a corresponding preset target position.

The first-level alarm time is the time when the vehicle collides with a preset first probability, and the second probability is greater than the first probability, namely the possibility of collision of the second probability is higher than the first probability.

In the present embodiment, the seat is a seat in a main driving position of the vehicle. In alternative embodiments seats at other locations in the cabin of the vehicle are also possible.

In this embodiment, when the current time is between the secondary alarm time and the predicted collision time, it is indicated that the vehicle has a very high risk of collision, and at this time, safety protection of the vehicle personnel can be effectively realized in subsequent possible collisions by timely adjusting the side wing mechanism, the rear lifting mechanism, the slide rail mechanism and the backrest rotating mechanism of the vehicle seat to respective preset target positions, that is, safety positions, so as to improve the safety of the vehicle through an active safety technology. When the current moment is between the primary alarm moment and the secondary alarm moment, the fact that the vehicle has a higher risk of collision with a low probability is shown, at the moment, safety protection of people on the vehicle can be effectively achieved in subsequent possible collision by timely adjusting the side wing mechanisms of the vehicle seat to the corresponding preset target positions, and the arrangement mode of the embodiment can balance the safety and riding comfort of the people on the vehicle.

Example 2

The embodiment provides a pre-collision processing method of a vehicle seat, which is a further improvement on the basis of embodiment 1, and specifically, the pre-collision processing method further comprises the following steps:

judging the direction of the pre-collision, and when the pre-collision is a rear collision, adjusting the direction of the step of adjusting the side wing mechanism to the corresponding preset target position to be the direction of unfolding the side wing mechanism, wherein the target position of the side wing mechanism is the position capable of being unfolded to the maximum; when the vehicle is in a frontal collision, the adjusting direction of the step of adjusting the wing mechanism to the corresponding preset target position is the direction of tightening the wing mechanism, and at this time, the target position of the wing mechanism is the position capable of being tightened to the minimum. In addition, when it is a frontal collision, as shown in fig. 5, the secondary alarm processing step 103 further includes the steps of:

and 103-3, adjusting the front lifting mechanism to a corresponding preset target position.

Likewise, in alternative embodiments, the order of steps 103-1, 103-2, 103-3 may be adjusted, and even the order of adjustment of the various mechanisms in step 103-2 may be adjusted. That is, the present invention does not limit the adjustment sequence of each mechanism, and the way of adjusting the wing mechanism first and then adjusting the other mechanisms is only illustrated in this embodiment, and does not limit the protection scope of the present invention.

The front lifting mechanism is used for adjusting the height of the front end of the cushion, and at the moment, the front lifting mechanism is the highest position of the front end of the cushion to the corresponding preset target position. Tests prove that the higher the height of the front end of the seat cushion is adjusted by the front lifting mechanism in the front collision, the more beneficial the safety of the seat occupant is to be protected. However, the effect of the adjusting pre-lift mechanism on the protection effect in the event of a collision is not significant in the event of a rear collision, and side effects may occur. The front lift mechanism is not adjusted during a rear impact in this embodiment.

In the embodiment, different processing modes are adopted for different directions of pre-collision, specifically, different processing modes are adopted for front collision and rear collision, a processing mode of tightening a side wing mechanism is adopted for front collision, and meanwhile, a front lifting mechanism of the seat is adjusted; in the case of a rear collision, the deployment of the wing mechanism is used. Experiments prove that the arrangement can better protect the safety of passengers on the seats in the cabin when collision happens.

With the development of the technology, an ideal processing mode is that all motors can be started at the first time, so that each mechanism can reach a preset target position at the fastest speed. In specific implementation, the moving direction of the motor needs to be determined according to the current position and the target position of the corresponding mechanism, and details about the direction of the motor are not described herein.

As shown in FIG. 6, step 103 '-1 of the primary alarm processing step 103' further comprises the following steps:

The arrangement can improve the safety of the passengers on the seat in the subsequent possible frontal collision process in an active safety mode.

Referring to fig. 14, there is shown a schematic time chart of the activation of each mechanism for one case of a rear end collision in a concrete application example of the pre-collision processing method for a vehicle seat according to embodiment 3 of the present invention. In this example, the pre-crash signal occurs when the primary alarm state is entered before the secondary alarm state.

And when t is between t2 and t1, entering a primary alarm processing flow, specifically, emitting a primary alarm sound, and unfolding the side wings to the maximum position. With the lapse of time, when the current time t is between t1 and t0, a secondary alarm processing flow is entered, specifically, a secondary alarm sound is emitted, the side wings are unfolded to the maximum position, and the slide rail mechanism is adjusted to a corresponding safe area, namely, a target position; adjusting the backrest to a corresponding safe area through a backrest rotating mechanism; the rear lift mechanism adjusts so that the seat cushion is at the lowest position.

In this example, the pre-crash signal skips the primary warning state and goes directly to the secondary warning state, such as in the case of an active safety process initiated by a pre-crash warning caused by a sudden vehicle breakthrough during vehicle travel. Where t2, t1, and t0 correspond to the primary alarm time, the secondary alarm time, and the predicted collision time in embodiment 3, respectively, and t is a variable, which is the current time.
