[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides an embodiment: a driving assistance device, including a wearable head 4 for wearing on a human body, a fixed head 8 for installation and connection with a vehicle body, and a response terminal including but not limited to sound, light, and / or image and / or tactile components. As those skilled in the art can understand, the response terminal can be an electroluminescent component such as an LED light, a speaker, a display screen or a vibration motor, etc., so as to facilitate the use of reminding the driver himself or the vehicle behind.

[0019] Specifically, a winding chamber 7 is provided inside the fixed head 8, and a winding reel 10 is provided inside the winding chamber 7. A connecting belt 2 is wound on the outer side of the winding reel 10, and one end of the connecting belt 2 is provided with a USB connector 1 plugged into the winding reel 10. The winding reel 10 is provided with a slot for installing the USB connector 1. A side cover 9 is provided on the fixed head 8. When the connecting belt 2 is fully unwound, the slot is arranged tangentially to the direction of the belt threading hole 6. The plug-in design of the USB connector 1 and the slot facilitates the replacement of the connecting belt 2 and can automatically separate the connecting belt 2 from the winding reel 1 after being stressed, so as to facilitate emergency exit from the vehicle. A belt threading hole 6 is provided on the fixed head 8, and the other end of the connecting belt 2 passes through the belt threading hole 6 and is connected to the wearable head 4. A plurality of muscle sensors 5 are provided on the inner side of the wearable head 4, and an FPC cable electrically connected to the muscle sensor 5 is provided inside the connecting belt 2.

[0020] A torsion spring 12 is provided inside the fixed head 8 at one end of the winding reel 10, and a processor 11 is provided inside the fixed head 8 at the other end of the winding reel 10. The processor 11 has a power module or is connected to the vehicle power supply through a wire, and the processor 11 is electrically connected to the response terminal.

[0021] In this embodiment, in order to achieve tactile response, the response terminal includes a micro air pump 13 and an airbag 3. The micro air pump 13 is installed inside the fixed head 8 and is electrically connected to the processor 11 through a wire. The slot portion is used as the final air outlet of the air pump. The output end of the micro air pump 13 is connected to the winding reel 10 through a rotating joint. The airbag 3 is installed on the inner side of the wearable head 4. The airbag 3 is connected to an air duct extending to one side of the USB connector 1. The air duct can be arranged inside the connecting belt 2. The slot portion on the winding reel 10 is provided with a through hole connected to the output end of the air pump. When the USB connector 1 is plugged in, the air duct can be connected to the through hole, and the muscle sensor 5 is arranged on the outside of the airbag 3. An external connector of the muscle sensor 5 can also be provided to adapt to the use of an added electrode sheet muscle sensor.

[0022] The micro air pump 13 has two functions to choose from, so that it can be convenient to increase the tightness of wearing after inflation and improve the detection accuracy of the muscle sensor 5. On the other hand, it can also be used to achieve pneumatic massage by setting multiple independent air bags 3 that conform to the human body design. The inflation simulates the effect of squeezing massage to relieve driving fatigue or remind the use of fatigue driving. Therefore, the design shape or number of the air bags 3 can be arbitrary. Regarding the use of the muscle sensor 5, when it can contact the human skin, the electrode sheet in the prior art can be selected to be attached to the human skin for detection. However, in order to facilitate the detection of wearing outside the clothing, the muscle sensor 5 It can be a pressure sensor. When the foot controls the brake, the leg muscles will produce a specific change pattern, and the muscle activity will produce an orderly change in pressure. After the signal conversion processing by the processor 11, an electrical signal can be generated for programmed control. For example, when the muscles are relaxed or there is no activity change for a long time, an inflation prompt is used to avoid fatigue driving. When the muscles are urgently tightened and the muscles in the adapted part produce a pressure change signal, it can be determined that the human body has braked while driving. At this time, the processor 11 controls the LED light to light up to remind the rear vehicle to pay attention to braking to avoid rear-end collision, and the LED light should be placed on the rearview mirror or rear window of the vehicle to facilitate observation and discovery by the rear vehicle.

[0023] Furthermore, in order to achieve light response, the response terminal also includes an LED lamp, which is separately external to facilitate independent light display after receiving signals. The LED lamp and the processor 11 are both equipped with wireless communication units such as Bluetooth modules for wireless control.

[0024] Finally, if Figure 3 and Figure 4 As shown, the wearing head 4 is in the shape of a conical sleeve or a flexible cloth strip with a side opening, and is used to be worn on the calf of a human body. When the wearing head 4 is in the shape of a flexible cloth strip, magic hooks 14 and magic hairs 15 are respectively provided on both sides of the two ends of the wearing head 4 to facilitate the tightening and fixing of the calf.
