Description

Technical Field

[0001] This application relates to the field of child car seat safety technology, and in particular to a support control method, support system, storage medium and electronic device for a child car seat. Background Technology

[0002] Current rear-facing child seats typically use an ISO-FIX connector and a support leg structure, with the support leg directly contacting the floor. When the vehicle is in normal driving conditions, children of different sizes require different seat angles for comfort. Existing child seat backrests only have two adjustment positions, which cannot accommodate children of various sizes. Furthermore, in the event of a collision, the child seat's inertial movement compresses the support leg structure, transferring the force to the floor. The floor structure, mainly composed of carpet, foam, sound insulation, and sheet metal, has low rigidity and is easily deformed under stress. This can cause the child seat to tilt too far, increasing the risk of rear-facing children's heads colliding with the front seat back, significantly increasing the risk of injury. Current vehicles only have ISO-FIX connectors for child seats in their design, without specific consideration for child seat protection within the vehicle as a whole. Therefore, a support system and control method for supporting and protecting child seats is needed. Summary of the Invention

[0050] Child car seat support control methods:

[0051] The child seat support control method in the embodiments of this application, such as... Figure 1 As shown, it includes:

[0052] Step S101: In response to the collision signal, determine the collision type;

[0053] Step S102: Adjust the height of the support structure according to the collision type. The support structure is located below the support leg of the child seat.

[0054] In this embodiment, a support structure is provided in the support area of ​​the child seat support leg on the vehicle floor. The support structure is made of a high-rigidity material, such as steel, to ensure that the support structure can provide strong support for the child seat support leg in the event of a vehicle collision.

[0055] After the vehicle starts, collision signals from the onboard electronic control unit can be monitored in real time. When a collision signal is detected, the collision type can be determined by analyzing the signal. Collision types can include at least frontal collisions, rear-end collisions, and side collisions. Then, based on a preset height adjustment strategy, a target adjustment strategy is determined. The height of the support structure is adjusted according to the target adjustment strategy to ensure that the support structure can effectively support the child seat's support legs, preventing or reducing injury to the child due to inertial instability or swaying. In the preset height adjustment strategy, one adjustment strategy is set for each collision type, and the adjustment strategy corresponding to the collision type is selected as the target adjustment strategy.

[0056] In this embodiment, a support structure is provided under the support leg of the child seat to support the child seat. When a collision signal is received, the height of the support structure is adjusted according to the collision type. When a collision occurs, the support structure is raised to provide support for the child seat. Different height adjustment strategies are corresponding to different collision types to achieve the best protective support effect for the child seat.

[0057] In one embodiment, adjusting the height of the support structure according to the collision type specifically includes:

[0058] When the collision type is a frontal collision, the collision speed is obtained;

[0059] The rising speed is determined based on the collision speed, and the support structure is controlled to rise at the rising speed.

[0060] In a frontal collision, the child seat will tilt forward due to inertia, and the support legs will exert pressure on the support structure. At this time, the support structure is controlled to rise at an upward speed to counteract the pressure of the child seat tilting forward, thereby reducing or preventing the child seat from tilting forward. After the support structure rises to a preset height, it remains at that preset height. The preset height can be set according to the structure type of the child seat, or it can be set to the maximum height of the support structure.

[0061] Furthermore, the greater the collision speed, the greater the instantaneous pressure when the child seat tilts forward. In this embodiment, the rising speed of the support structure is determined based on the collision speed, so that the support structure can provide a counteracting force that matches the current collision speed, thereby achieving a better support effect for the child seat.

[0062] Furthermore, determining the ascent speed based on the collision speed and controlling the support structure to rise at the ascent speed specifically includes:

[0063] If the collision speed is greater than or equal to a preset speed threshold, the support structure is controlled to rise at a first speed; otherwise, the support structure is controlled to rise at a second speed, where the second speed is less than the first speed.

[0064] The preset speed threshold, the first speed, and the second speed can all be determined based on the simulation test results during the vehicle development period. When the collision speed is greater than or equal to the preset speed threshold, the support structure rises at the first speed. When the collision speed is less than the preset speed threshold, the support structure rises at the second speed, which is less than the first speed.

[0065] This application embodiment, by setting a preset speed threshold, a first speed, and a second speed, compares the collision speed with the preset speed threshold, which can quickly determine the rising speed of the support structure, thereby improving the rising response speed of the support structure.

[0066] In one embodiment, adjusting the height of the support structure according to the collision type specifically includes:

[0067] When the collision type is a rear-end collision, the real-time pressure of the supporting structure is obtained;

[0068] If the real-time pressure of the support structure is less than or equal to the first preset pressure, the support structure is controlled to rise at a third speed until the real-time pressure on the surface of the support structure is greater than the first preset pressure and is maintained for a first preset period of time.

[0069] In a rear-end collision, the vehicle experiences a forward impact force. Due to inertia, the child seat tilts backward, causing its support legs to lift off the floor and sway back and forth. At this point, the control support structure rises at a third speed to provide support to the support legs, thus preventing and mitigating the swaying of the child seat.

[0070] Specifically, when the collision type is determined to be a rear-end collision, the real-time pressure of the supporting structure is obtained by installing a pressure sensor on the surface of the supporting structure. A first preset pressure is set, which can be set to 0N-10N. If the real-time pressure of the supporting structure is less than the first preset pressure, it is determined that the child seat's support leg has detached from the supporting structure, and the child seat has shaken. At this point, the supporting structure is controlled to rise at a third speed until the real-time pressure on the surface of the supporting structure exceeds the first preset pressure and remains at a first preset time. If this is the case, it is determined that the supporting structure has supported the child seat, and the supporting structure stops rising, maintaining its current height. If, after the supporting structure rises to its maximum height, the real-time pressure on the surface of the supporting structure is still less than or equal to the first preset pressure, the supporting structure is controlled to maintain its maximum height.

[0071] In this embodiment of the application, when a rear-end collision occurs, the support structure detects in real time the pressure of the support structure and when the support leg detaches from the support structure, it controls the support structure to rise at a third speed to provide support for the support leg, so as to avoid and reduce the shaking of the child seat, and stops rising after the support structure stably supports the support leg, thus maintaining support for the child seat.

[0072] In one embodiment, the support structure includes a left support plate and a right support plate, which are arranged along the width direction of the vehicle. The lifting height and lifting speed of the left and right support plates can be adjusted independently. It should be noted that the description of the positions of "left" and "right" here refers to the left and right sides when facing the front of the vehicle, and this definition will continue to be used thereafter.

[0073] The adjustment of the height of the support structure according to the collision type specifically includes:

[0074] When the collision type is a side collision, the collision direction is obtained;

[0075] The left support plate and / or the right support plate are raised according to the collision direction.

[0076] When a side collision occurs, the vehicle is subjected to an impact force from the side. Due to inertia, the child seat will tilt to the side of the impact. At this time, the support plate on the side of the impact is controlled to rise according to the direction of the collision to provide lateral support to the child seat and straighten it. Alternatively, the left and right support plates are controlled to rise at different speeds to provide different levels of support to the left and right sides of the child seat and straighten it.

[0077] Furthermore, controlling the left support plate and / or the right support plate to rise according to the collision direction specifically includes:

[0078] If the collision direction is to the left, then control the left support plate to rise at the fourth speed and control the right support plate to rise at the fifth speed, wherein the fifth speed is less than the fourth speed;

[0079] If the collision direction is to the right, then the right support plate is controlled to rise at a sixth speed, and the left support plate is controlled to rise at a seventh speed, wherein the seventh speed is less than the sixth speed.

[0080] Specifically, in the event of a left-side collision, the left and right support plates rise simultaneously, with the left support plate rising at a faster rate than the right. This provides support to the left side of the child seat's support legs during the ascent, causing the child seat to tilt to the right and counteract the leftward tilt caused by the collision. Similarly, in the event of a right-side collision, the right support plate rises at a faster rate than the left support plate, providing support to the right side of the child seat's support legs, causing the child seat to tilt to the left and counteract the rightward tilt caused by the collision. The fourth speed can be equal to the sixth speed, and the fifth speed can be equal to the seventh speed.

[0081] After a side impact, the vehicle will eventually return to a relatively stable state. Therefore, the left and right support panels will rise to the preset height at different speeds and then remain at the preset height. The preset height can also be set according to the structure type of the child seat, or it can be set to the maximum height of the support structure. After the vehicle returns to a stable state, the height of the support panels will be adjusted from the preset height to the height of the vehicle in normal driving condition. In this state, the child is more comfortable, and if a secondary collision occurs, the structure can function normally, enhancing the protection of the child and reducing the risk of injury.

[0082] In this embodiment, after a side collision, the support plate on the side controlling the direction of the collision rises at a faster speed, while the support plate on the other side rises at a slower speed. This provides the child seat with a support force opposite to the direction of the collision at the moment of impact, keeping the child seat as upright as possible. It also ensures that the left and right support plates are level after the vehicle returns to a stable state, preventing the child seat from tilting.

[0083] In one embodiment, the method further includes:

[0084] In response to a support structure pressure being greater than or equal to a second preset pressure and maintained for a second preset period of time, the current support structure pressure is obtained;

[0085] The target height of the support structure is determined based on the current pressure on the support structure, and the support structure is controlled to adjust to the target height.

[0086] Specifically, after the vehicle starts, the pressure on the support structure is continuously monitored. A second preset pressure is set, slightly higher than the pressure applied to the support structure when the child seat is not occupied. When the detected support structure pressure is greater than or equal to the second preset pressure and maintained for a second preset period, it is determined that a child is sitting in the child seat. At this time, the child's weight or body size is determined based on the current support structure pressure, and the target height of the corresponding support structure is further determined to adapt the height of the child seat to the child's body size, thereby improving the child's riding comfort.

[0087] This application embodiment determines whether a child is riding by monitoring the pressure change of the support structure. After detecting that a child is riding, the target height of the support structure is adjusted according to the current support structure pressure. This allows for setting an appropriate height based on the child's body size, thereby improving the child's riding comfort.

[0088] Figure 2 A flowchart of a child seat support control method according to a preferred embodiment of this application is shown, specifically including:

[0089] Step S201: In response to the support structure pressure being greater than or equal to the second preset pressure and maintained for the second preset period of time, obtain the current support structure pressure;

[0090] Step S202: Determine the target height of the support structure based on the current pressure on the support structure, and control the support structure to adjust to the target height;

[0091] Step S203: In response to the collision signal, determine the collision type. If the collision type is a frontal collision, proceed to step S204. If the collision type is a rear collision, proceed to step S205. If the collision type is a side collision, proceed to step S206.

[0092] Step S204: Obtain the collision speed. If the collision speed is greater than or equal to a preset speed threshold, control the support structure to rise at a first speed; otherwise, control the support structure to rise at a second speed, where the second speed is less than the first speed.

[0093] Step S205: Obtain the real-time pressure of the support structure. If the real-time pressure of the support structure is less than or equal to the first preset pressure, control the support structure to rise at the third speed until the real-time pressure on the surface of the support structure is greater than the first preset pressure and maintain it for the first preset period of time.

[0094] Step S206: Obtain the collision direction. If the collision direction is to the left, control the left support plate to rise at the fourth speed and control the right support plate to rise at the fifth speed, with the fifth speed being less than the fourth speed. If the collision direction is to the right, control the right support plate to rise at the sixth speed and control the left support plate to rise at the seventh speed, with the seventh speed being less than the sixth speed.

[0102] The drive assembly 03 drives the rack 13 to slide the lower end of the first rod 14 to achieve the extension and retraction of the hinge frame, thereby pushing the support plate 02 to rise and fall. As an example, the drive assembly 03 uses a drive motor, the rack 13 is provided with serrations, the output shaft of the drive motor is connected to a gear 31 and meshes with the serrations on the rack 13, when the gear 31 rotates, it drives the rack 13 to slide along the first guide rail 12.
