[0002] The outer water cut of the car door is clamped on the upper edge of the outer panel of the door. The flocking of the outer water cut is attached to the outside of the door glass and has a certain amount of compression. When raising or lowering the door glass, the outer water cut can prevent dust, rain and other debris from entering between the inner and outer panels of the door, and together with the inner water cut, it plays the role of clamping the glass to prevent the glass from shaking too much. In addition to the above functions, the outer water cut can also play a certain role in sound insulation and heat preservation. When driving at high speed, the outer water cut can also reduce the interference of wind noise and improve the quietness effect in the car. At the same time, the outer water cut can also reduce the temperature exchange between the inside and outside of the car, making the car warmer and improving the airtightness.

[0030] A vehicle external water-cut luminous system can be applied to both gasoline vehicles and electric vehicles, and includes: an external water-cut bright strip 4 and an external water-cut cover 3, an internal luminous light strip 6, a micro solar panel 7, a human body sensing sensor 22, a micro controller 8 and an external water-cut back cover 9, an external water-cut body 14 is on the inner side of the external water-cut back cover, an external water-cut steel strip 13 is embedded inside the external water-cut body 14, the entire external water-cut is clamped on the external panel edging 1, and the external water-cut flocking 15 is compressed and fitted with the door glass 2, with a certain amount of compression; the micro solar panel 7 is connected to the external panel edging 1, and the external water-cut flocking 15 is compressed and fitted with the door glass 2, and has ... The solar panel internal wiring harness a5 and the micro solar panel internal wiring harness b10 are connected to the human body sensing sensor 22; the human body sensing sensor 22 is connected to the micro controller 8 through the human body sensing sensor wiring harness e23 and the human body sensing sensor wiring harness f24; the micro controller 8 is connected to the external water-cut light belt 6 through the controller internal wiring harness c11 and the controller internal wiring harness d12; the external water-cut housing 3 and the light-emitting light belt part 6 arranged inside the external water-cut housing 3, the micro solar panel 7, the human body sensing sensor 22 and the micro controller 8 are packaged through the external water-cut back sealing plate 9;

[0031] An outer water-cut steel strip 13 is arranged inside the outer water-cut, and an outer water-cut front connection angle 16 and an outer water-cut rear connection angle 17 are arranged at both ends of the outer water-cut body 14; an outer water-cut bright strip 4 is arranged outside; the outer water-cut cover shell 3 and its internal components and the outer water-cut back sealing plate 9 are clamped on the outer water-cut bright strip 4 through the 6 outer plate clamping structures 19 on the outer water-cut cover shell 3; the outer water-cut inside the self-powered luminous outer water-cut is clamped on the door outer panel 1; the working principle of the outer water-cut is that sunlight can pass through the outer water-cut transparent cover shell and the transparent light strip to charge the solar panel inside, and the solar panel is connected to the human body sensing sensor and the microcontroller, the human body sensing sensor is responsible for sampling signals, and the microcontroller is responsible for sampling signals for state control and charging control, sending out a driving signal, and performing discharge control, so that the outer water-cut light strip is lit;

[0032] The above system can use the micro battery to supply power independently and work when the vehicle is stopped. Even if the power is exhausted, it will not affect the start of the car. The charging and discharging of the micro battery is driven by the micro controller 8. The micro controller 8 includes a charging control circuit and a discharging control circuit. The charging control circuit is provided with two output interfaces, one input interface is connected to the micro solar panel, and the other input interface is connected to the car battery. The output interface of the charging control circuit is connected to the micro battery. The battery on the car can be used to charge the micro battery while driving, and the remaining power of the micro battery can be maintained as much as possible to increase its parking state. In order to ensure the endurance of the vehicle, when the vehicle is not used for a long time, it can also use solar energy to self-charge, meet certain electricity needs and achieve self-supply. When driving, when the power of the car battery is greater than the set upper threshold, for example, higher than 80%, the car battery is controlled to charge the micro battery to increase the charging efficiency of the micro battery, and when the car battery is lower than the set lower threshold, for example, lower than 60%, the car battery is stopped from charging the micro battery. Under the condition that the vehicle battery and charging motor are normal, the vehicle can continuously charge the micro battery after traveling a certain distance, and the charging will stop automatically when the micro battery is full.

[0033] The two poles of the micro battery are connected to the luminous light strip 6 through a discharge control circuit, which can control the operation of the luminous light strip 6. In order to facilitate the use of the luminous light strip 6 to meet more human-computer interaction functions, the present invention innovates the interaction method. The micro controller 8 is connected to the vehicle management system, can obtain vehicle information, and use the luminous light strip 6 to display vehicle parameter information. The luminous light strip 6 is composed of three parallel light strips of different colors. The luminous light strip 6 is provided with a red light strip, a green light strip, and a white light strip, that is, the luminous light strips 6 on both sides can display three different colors of red light strips, green light strips, and white light strips.

[0034] During specific operation, when the human body sensing sensor 22 senses the user, the luminous light strip 6 is controlled to light up according to the set logic. The human body sensing sensor 22 can be designed as needed, such as an infrared sensor, a camera using algorithm recognition, etc. The set logic lighting can be designed as needed. If the flowing lights are lit around the vehicle, a cool effect will be formed, and the luminous light strip 6 will be turned off after a set time after the user cannot be sensed, for example, a delay of 10 seconds. Of course, the lighting logic and the delayed closing time can also be defined in the vehicle system.

[0035] When the vehicle senses the user's key, the luminous light strip 6 is started to execute the welcoming mode or the seeing-off mode. The welcoming mode can be designed as needed. For example, according to the distance between the key and the vehicle, the red light is first lit, then the white light is lit, and finally the green light is lit. The vehicle is unlocked when the green light is lit. The red light is the most conspicuous, which is convenient for the user to find the vehicle in time when approaching the vehicle, and to locate the welcoming guest. After the user approaches to a closer distance, the white light or the energy indication is lit for conventional welcoming. Finally, when the user arrives next to the cab, the green light is lit, indicating that the vehicle has been unlocked. The welcoming prompt is also a prompt of the vehicle's locked status. When the user does not enter the vehicle but leaves, or the user turns off the engine and gets off, the seeing-off mode will be executed. In this mode, the green light is lit when the user just gets off the vehicle. When the user and the key reach the locking position, the car is locked and the white light is lit or the energy indication is executed. When the user moves away, the red light will be displayed, and the luminous light strip will be turned off after the key set time (such as 5 seconds) cannot be sensed, giving customers a cooler experience.

[0036] Energy indication can timely inform the user of the remaining power or fuel of the car before getting on or after getting off. The specific display modes include: getting on indication and getting off indication;

[0037] Among them, the on-board indication: according to the remaining fuel or the percentage point of lighting, the green light strip of the corresponding percentage in the single-side light strip 6 is lit, and the white light strip of the remaining power is displayed on both sides simultaneously. The user faces the vehicle, and the left side continuously displays the green light strip to indicate the remaining energy, while the remaining part is displayed in white light strip;

[0038] Get off instruction: According to the remaining fuel or power percentage, light up the corresponding percentage of the green light band in the single-sided luminous light band 6, and light up the corresponding percentage of the red light band in the single-sided luminous light band 6 according to the fuel or power percentage used in this trip, and light up the remaining power white light band, and the green light band, red light band, and white light band are continuous in sequence.

[0039] When the vehicle triggers the guard mode, the red, green and white light strips flash alternately and turn off after the guard mode ends to warn pedestrians around. The alternating flashing can also simulate the feeling of police lights and reduce the probability of vehicle damage.

[0040] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
