Description
Technical Field
The embodiment of the utility model provides an automatic intelligent car seat headrest of adjustment height relates to the auto-parts field.
Background
The position of the headrest of the car seat has a great influence on the safety of the passengers. People with different heights need to adjust the height of the headrest when taking the chair. When the headrest is adjusted too low, whiplash injury is easily caused when a rear-end collision happens, and the cervical vertebra is injured; when the headrest is higher, if the headrest of the front passenger seat is higher, the view beside the head-twisting observation of the driver is influenced, and the view in front of the middle and rear row passengers can be observed; the too high back row headrest will disturb the driver to observe the view behind the vehicle from the inside rear-view mirror, and there is a potential safety hazard.
Currently, there is no automobile seat headrest on the market which can automatically adjust the height according to the head position of the passenger and automatically lower to the lowest position when no person sits.
A seat headrest control device (CN202106880U) of the prior art aims to lower the rear headrest when backing a car, enlarge the view of the driver and present the danger of rear-end collision when backing a car. The automobile seat patent (CN205737035U) with automatic adjustment state only records the position of the seat adjusted by different drivers, and realizes adjustment through the seat memory function, and is only limited to the driver seat, and is not actively adjusted. A self-adjusting method and system (CN108058630A) for seat headrest is to adjust the height of the headrest by actively leaning the head of the passenger against the headrest and detecting the pressure center of the head contact area of the passenger by the pressure sensor on the headrest to judge the head position. If the passenger does not actively contact the head with the headrest, the adjustment function cannot be realized, and the passenger is passive. A seat system, a vehicle and a method (CN108312928A) for adjusting the height of a headrest describe the function of actively detecting the height of the head of a passenger, but do not have the other function of the patent, and actively lower a non-driver seat when no person is detected to be seated or locked.

The embodiment of the utility model provides a have following advantage:
the utility model discloses an automatic intelligent car seat headrest of adjustment height, whether someone sits on car seat through the camera detection, the human head center of while discernment, and judge line and seat benchmark high position and the contained angle alpha of infrared ray sensor line of head center and infrared ray sensor according to the position of the camera shooting picture that the head center is located, infrared ray sensor detects the distance L1 with human head, and detect the distance L2 with seat benchmark position sensor, seat benchmark position sensor can read its height H1 to the headrest center. The detected information is transmitted to the central processor, and the height H2 of the head center and the seat reference position sensor can be calculated through the two sets of distance parameters L1 and L2 and the formed included angle alpha. The height position H1 of the headrest is thus adjusted by the central controller to properly fit the human head. Meanwhile, when no person is detected on the non-driver seat, the headrest is automatically retracted, the visual field range of a driver is enlarged, the safety factor in the driving process is increased, and when the vehicle is locked, the headrest of the non-driver seat is automatically lowered to the lowest position.
