Description

Technical Field

[0001] The present invention belongs to the field of automotive collision safety, and particularly relates to an active child seat system. Background Art

[0002] For traditional child seats, children sit upright. In the event of a collision, a child's neck will be strongly stretched forward by the head, causing neck fractures. Moreover, for vehicles with a small rear row space, in the event of a vehicle collision, a child's head is likely to hit the backrest of the front seat, endangering the child's life safety. Summary of the Invention

[0003] To overcome the above problems, the present invention provides an active child seat system. When a vehicle collides, the active safety system composed of a multi-functional camera and radar or the airbag control unit, and the passive safety system composed of an acceleration sensor can identify the collision condition, and transmit the signal to the child seat. The child seat body can rotate backward to make the child lie in a reclined position, so as to reduce or avoid the injuries suffered by the child's neck and head. Brief Description of the Drawings

[0008] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0009] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0010] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", and "right" are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0011] Refer to Figure 1 , an active child seat system, including a child seat body 1, a backrest end moving structure 2, a driving device end moving structure 3, a driving device 4, a base 5, a child seat and vehicle connection device 6, an airbag control unit 7, a multi-functional camera system 8, a buffer material 9, and a wire harness 10. Among them, the child seat body 1 is fixedly connected to the backrest end moving structure 2, the driving device moving structure 3 is fixedly connected to the driving device 4, the backrest end moving structure 2 and the driving device moving structure 3 can perform a sliding movement, the driving device 4 is fixedly connected to the base 5, the child seat and vehicle connection device 6 can fix the child seat on the vehicle and maintain communication, the airbag control unit 7 is connected and communicates with the multi-functional camera system through the wire harness, and the airbag control unit 7 communicates with the child seat and vehicle connection device 6.

[0012] The buffer material 9 is composed of EPP foam or other materials and structures with the same function, and can provide buffer protection for the child's pelvis, back, and head when the vehicle collides.

[0013] The present invention also provides an operation method for an active child seat system, comprising the following steps:

[0014] Step 1: Set a vehicle collision or impending collision recognition threshold in the central processor of the multi-functional camera system 8, so as to recognize the occurrence of a collision in advance through the multi-functional camera system 8 before a vehicle collision accident occurs or just when the collision contact occurs, or recognize the occurrence of a collision through the airbag control unit 7 by means of a collision signal at the time of collision;

[0015] Step 2: The airbag control unit 7 receives the electrical signal of the multi-functional camera system 8, or recognizes the electrical signal according to its own built-in acceleration sensor, and converts the electrical signal into an electric current and sends it to the driving device 4;

[0016] Step 3: The driving device 4 causes the backrest end moving structure 2 and the driving device end moving structure 3 to slide relative to each other according to gears or other equivalent power structures, so that the child seat backrest becomes horizontal and the seat cushion becomes vertical, achieving the protection of the child's head and cervical vertebrae.
