[0003] However, the number of vehicles with the increase of traffic has increased dramatically. Apart from human factors such as alcohol abuse and illegal driving, it is usually impossible to observe the vision because of the high speed and no warning device. The area of the dead end 'causes the driver to have no time to slow down or brake, resulting in personal injury and property damage. [0004] Visually occupies an important position in people's access to information, about 80% of the information is obtained by the human eye, and the driver gets more than 90% of the information when driving the vehicle. Therefore, the eye-opening status of the driver is closely related to driving safety. Under normal circumstances, when the eyes are closed, the eye closing time is between 0. 12 ** 0, 13 seconds'. In the process of driving, if the eye closes for more than 0.15 seconds, it is prone to traffic accidents. When the driver's eyes are tired, 1013369657-0 09613915 (P_ delete 1 ^ 3 1 7 ^ 14 1 1379785 on September 27, 2003, when the shuttle is replacing the page and dozing, etc., it is prone to excessive eye closure time, Therefore, the driver cannot obtain traffic information accurately and in time, and is prone to traffic accidents. [0005] In order to solve the above problems, the prior art provides an in-vehicle safety device for a vehicle, which must be placed in front of the driver to accurately capture the driver's eyes. Department activities. However, the device occupies the space in front of the driver, affecting the driver's vision, and increases the danger of driving to a certain extent. Moreover, the device uses visible light imaging to detect the driver's eye activity, which is not suitable for nighttime use. [0006] In view of the above, it is necessary to provide an in-vehicle safety device that prevents the driver's eyes from being closed for a long time, can not occupy the space in front of the driver and can clearly detect the driver's eye movement, and utilizes the feeling of the human eye. Infrared source radiation is detected to make it safer, more suitable for night driving and more capable It is safely applied to a vehicle having a front windshield having an infrared reflection effect. [0007] The present invention provides an in-vehicle safety device for a vehicle having a front windshield, and the vehicle safety device includes An infrared reflective film, an infrared light source, an infrared detecting device, and an alarm device. The infrared reflecting film is attached to the front windshield surface, and the infrared light source emits infrared light to illuminate the driver's eyes. The infrared detecting device is disposed under the front windshield, and the infrared light reflected by the driver's eye is reflected by the infrared reflective film to reach the infrared detecting device. The infrared detecting device includes an infrared optical system. And an infrared detecting device comprising an infrared sensor and a signal processing circuit 09613915 (^^^^ A〇101 page 4/total 14 pages 1013369657-0 1379785 101: year. September 27th Positively replacing the page, the infrared light reflected by the driver's eye reaches the infrared optical system after being reflected by the infrared reflective film, and the infrared optical system drives the driving The infrared light reflected by the eye is focused on the infrared sensor, and the infrared sensor converts the radiant energy of the infrared light reflected by the driver's eye into a processable electrical signal, and the signal processing circuit can process the The electrical signal is processed such that the infrared detecting device detects infrared light that is different from that reflected by the driver when the eye is closed and opened to obtain the driver's eye closing time, thereby emitting a corresponding time of the closing time. The electrical signal receives the electrical signal and determines whether an alarm signal is issued. [0008] The present invention also provides an in-vehicle safety device for use on a vehicle having an infrared reflected front windshield, so that the vehicle is safe. The device may not be provided with an infrared reflective film. [0009] Compared with the prior art, the vehicle safety device, in addition to the infrared reflective film, may be disposed under the front windshield or partially embedded in the vehicle body, and the infrared reflective film does not affect the driver. The line of sight, so that the vehicle safety device can clearly detect the driver's eye closing time without affecting the driver's field of vision and improving safety. [Embodiment] The present invention will be further described in detail below with reference to the drawings.

After the reflective film 120 is reflected, the infrared detecting device 140 can be detected. The infrared detecting device 140 detects the infrared light reflected by the driver's eye 11 to obtain the closing time of the driver's eye 11, thereby issuing a The driver's eye 11 closes the time corresponding to the electrical signal, and the alarm device 150 accepts the control of the corresponding electrical signal and determines whether an alarm signal is issued. [0013] In the actual use process, in order not to affect the driver's line of sight, the infrared reflective film 120 has a light transmittance of more than 70%, preferably, the infrared reflective film is a magnetron sputtering metal film, the metal is optional copper, Stainless steel, or nickel-chromium alloy 〇 [0014] The infrared light source 130 is a specific infrared wavelength source, and the specific wavelength is in the range of 780-2100 Nile. [0015] The infrared detecting device 140 is generally disposed under the front windshield 15 to ensure that the space in front of the driver is not occupied, so as not to affect the driver's view, thereby posing a driving danger. Preferably, the infrared detecting device 140 can be partially buried in the vehicle body of the vehicle below the front windshield 15. [0016] In order to avoid interference from ambient sunlight, vehicle lights, etc., preferably, the infrared light source emits infrared light of a specific wavelength, and the infrared detecting device 140 receives only infrared light of the specific wavelength. 09613915(^^^51 A〇101 Page 6 of 14 page 1013369657-0 1379785 101.
