Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of vehicle interior, in particular to a light-emitting safety belt system, a vehicle and an interior light-emitting control method. BACKGROUND

[0002] Safety belts are mandatory safety devices for vehicles. Existing safety belts are usually black or the same color as the vehicle interior. To enhance the visibility of safety belts in dark environments, related technologies have a scheme of adding light-emitting materials to safety belt webbing and setting safety belts to be light-emitting. However, simply setting safety belts to be light-emitting will affect the driver's vision in the dark and affect driving safety. At the same time, simply light-emitting safety belts in the dark will cause a large difference between the light-emitting area of the safety belt and the non-light-emitting area of the vehicle interior, making it more difficult for users to see the seat area when getting into the vehicle, and affecting user experience. SUMMARY

[0003] To solve the problems in the prior art, the embodiments of the present disclosure provide a light-emitting safety belt system, a vehicle and an interior light-emitting control method, which can improve the visibility of safety belts while ensuring driving safety. The technical solution is as follows:

[0004] In a first aspect, a light-emitting safety belt system is provided, comprising a safety belt, a safety belt buckle and a seat interior, the surfaces of the safety belt, the safety belt buckle and the seat interior are provided with an electric light-emitting material, the light-emitting state of the electric light-emitting material can change according to the change of an input signal, the input signal comprises vehicle interior ambient light information, a vehicle door opening state and a vehicle running state, and the light-emitting state comprises whether the electric light-emitting material emits light and the light-emitting intensity of the electric light-emitting material.

[0005] In a second aspect, a vehicle is provided, comprising the light-emitting safety belt system provided in the first aspect.

[0006] In a third aspect, based on the light-emitting safety belt system provided in the first aspect or the vehicle provided in the second aspect, an interior light-emitting control method is further provided, comprising:

[0007] Obtaining vehicle interior ambient light information, and generating a first light-emitting signal according to the vehicle interior ambient light information;

[0008] Obtaining a vehicle door opening state, and generating a second light-emitting signal according to the vehicle door opening state;

[0009] Obtaining a vehicle running state, and generating a third light-emitting signal according to the vehicle running state;

[0010] Generating a fourth light-emitting signal in response to a user instruction;

[0011] The light-emitting state and / or the light-emitting intensity of the light-emitting safety belt system are controlled according to the first light-emitting signal, the second light-emitting signal, the third light-emitting signal and the fourth light-emitting signal.

[0012] The technical solution provided by the embodiments of the present disclosure has the following beneficial effects:

[0013] The embodiments of the present disclosure provide a light-emitting safety belt system, a vehicle and an interior light-emitting control method. The safety belt, the safety belt buckle and the seat interior (the upper surface of the seat) of the vehicle are all designed in a controllable light-emitting form. In a dark light condition, the safety belt, the safety belt buckle and the seat interior can emit light, which facilitates the user to sit down and unfasten / fasten the safety belt. In addition, the light-emitting state of each part of the light-emitting structure is controllable. The light-emitting state can be changed according to the running state of the vehicle, so that the light-emitting state is reduced or no light is emitted when the vehicle is running, thereby avoiding the influence of light emission on the driver's vision and affecting the driving safety. In addition, the safety belt, the safety belt buckle and the seat interior are all designed in a light-emitting form, so that they can emit light at the same time. Therefore, when only the safety belt emits light and the seat interior does not emit light, the light-emitting area of the safety belt is dazzling, and the light-emitting area of the safety belt and the non-light-emitting area of the seat have a large difference in brightness, which makes it more difficult for the user to see the range of the seat. Therefore, the user experience is improved.

[0014] The advantages of the additional aspects of the present disclosure will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present disclosure. BRIEF DESCRIPTION OF DRAWINGS

[0015] In order to more clearly illustrate the technical solutions in the embodiments of the present disclosure, the following will briefly introduce the drawings needed to be used in the embodiment description. Obviously, the drawings in the following description are only some embodiments of the present disclosure, and other drawings can be obtained by those skilled in the art without creative labor.

[0016] Figure 1 It is a whole structure schematic diagram of a light-emitting safety belt system provided by the embodiments of the present disclosure.

[0017] The reference signs respectively represent: 1, safety belt buckle; 2, safety belt height adjuster; 3, safety belt; 4, seat. DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, the following will further describe the embodiments of the present disclosure in combination with the drawings.

[0019] The terms "first", "second", etc. in the description and claims of the present disclosure and the drawings are used to distinguish different objects, rather than to describe a specific order. The terms "up", "down", etc. are orientation terms, which are described based on the positional relationship of each part structure in the normal use state, and are only used to describe the relative positional relationship, and do not necessarily indicate the limitation of the orientation. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0020] As shown in the embodiments of the present disclosure, Figure 1 First, a light-emitting safety belt system is provided, which includes a safety belt, a safety belt buckle and a seat trim, the surfaces of the safety belt, the safety belt buckle and the seat trim are provided with an electrically light-emitting material, the light-emitting state of the electrically light-emitting material can change according to the change of an input signal, and the input signal includes vehicle interior ambient light information, vehicle door opening state and vehicle running state.

[0021] The existing safety belt webbing light-emitting, buckle light-emitting and other technologies are all safety belt assembly sub-component light-emitting, which needs to light up after the safety belt buckle is buckled, the buckle light-emitting area is not obvious, and the webbing itself light-emitting is more dazzling in dark driving, which is easy to cause traffic accidents, does not have automatic control function, does not consider the whole vehicle environment, and is not effectively integrated with the whole vehicle running state. Based on the above problems, the light-emitting safety belt, the light-emitting buckle and the light-emitting seat are integrated in the embodiments, which has the following advantages:

[0022] Under the condition of opening the door and dim light, the light-emitting safety belt system (buckle, webbing, lock tongue light-emitting), seat fabric and guard plate light-emitting, gives customers a warm welcome feeling, and avoids that the safety belt area and the seat area have too large light-dark contrast caused by separate safety belt lighting, so that the seat area is more invisible.

[0023] The light-emitting state of the light-emitting safety belt system can be automatically adjusted according to the vehicle running state, and the light-emitting brightness is dimmed or the light-emitting is turned off when the vehicle is running, so as to avoid that the light affects the driver's field of view during driving, or the reflection of the light-emitting structure on the front windshield affects the driver's field of view, and ensure driving safety.

[0024] After wearing, the light-emitting device such as safety belt buckle, safety belt lock tongue, safety belt webbing and seat fabric can be lighted up according to the customer's voice control and self-defined setting, so as to prevent driving safety caused by operation of the control software during driving.

[0025] Customer voice can customize the light color or follow the whole car interior atmosphere light and music to flash, with more than 256 color adjustment.

[0026] In this embodiment, the safety belt 3 includes a safety belt webbing and a safety belt tongue, and the safety belt webbing and the safety belt tongue are preferably designed in a light-emitting form. The purpose of increasing the light-emission of the safety belt tongue is to facilitate the quick finding of the safety belt tongue in a dark environment to wear the safety belt, thereby improving the wearing efficiency.

[0027] The safety belt webbing can be designed in a multi-color light-emitting or single-color light-emitting form. For the multi-color light-emitting, the light-emitting silk thread can be added in the weaving process to realize the light-emitting, and the light-emitting color can be controlled by the micro-current size. For the single-color light-emitting, the yarn with fluorescent material can be woven in the weaving process of the webbing. The yarn can absorb light through sunlight or light during the day and automatically emit light at night. In addition, the car enterprise LOGO can be further designed on the webbing to emit light. The power supply of the safety belt webbing can be realized through the fixed end, that is, the power supply of the safety belt webbing is fixed on the safety belt retractor through the connector and connected with the whole vehicle to realize the power supply of the light-emitting material on the webbing and the control of the light-emitting state. In some embodiments, for the safety belt webbing in the multi-color light-emitting form, when the webbing power supply current is 1-10 mA, the color of the light-emitting silk thread is red, the power supply current is 11-20 mA, the color is orange, the power supply current is 21-30 mA, the color is yellow, the power supply current is 31-4 mA, the color is green, the power supply current is 41-50 mA, the color is cyan, the power supply current is 51-60 mA, the color is blue, the power supply current is 61-70 mA, the color is purple, and the power supply current is 71-100 mA, the color is a flashing color. The flashing color can be further divided into different ways of flashing, such as different flashing frequencies and different colors.

[0028] The safety belt tongue emits light through the LED lamp tube. The LED lamp tube can be designed on the safety belt tongue. The light-emitting is uniform through the surface light-transmitting material and the light guide structure. The control of the light-emitting state can be realized by connecting the built-in wireless connection with the wireless device (such as Bluetooth and wireless WIFI) of the whole vehicle. The power supply demand can be met by the built-in battery, and the battery can be charged when the safety belt tongue is inserted into the lock buckle.

[0029] The safety belt lock buckle 1 emits light through the setting of the LED lamp tube. The light-emitting is uniform through the light-transmitting material and the light guide structure. The LED lamp tube can be directly connected with the wire harness of the whole vehicle to meet the power supply demand and realize the control of the light-emitting state.

[0030] The light-emitting of the seat 4 can be realized in two ways:

[0031] 1. The leather seat. The LED light strip is pre-buried in the foaming of the leather seat. The seat fabric is punched to form different types of light-emitting through the size and pattern of the punch. The seat control module is connected with the whole vehicle to meet the power supply and control demand.

[0032] 2. The seat knitted fabric is knitted with luminous yarn and emits light through micro-current control. The light emitting principle is the same as that of the multi-color light emitting safety belt webbing.

[0033] In addition, in some embodiments, the seat belt height adjuster 2 arranged on the B pillar of the vehicle can also be further designed as a light-emitting structure, and an electric light-emitting material is added to improve the overall appearance when the interior is lighted. The seat belt height adjuster emits light through a pre-embedded LED lamp tube, and the wire harness is connected to the vehicle wire harness through a pre-installed guard plate to meet the power supply and control requirements.

[0034] The embodiments of the present disclosure further provide a vehicle comprising the light-emitting seat belt system provided above.

[0035] The vehicle comprises a body control module, a domain controller module, a wire harness or CAN, a seat, a microphone, and the like. The body control module and the microphone input signals through the wire harness or CAN, the signals are judged by the domain controller module, and the signals are output to the light-emitting seat belt system (seat belt, seat belt buckle, and seat interior, etc.) through the wire harness or CAN to realize light lighting and control.

[0036] The logic judgment is as follows:

[0037] When the door is opened, the light is lit at the position of the opened door. The seat belt webbing, lock tongue, lock buckle, and seat skin light are lit by default (the default color is warm orange). After the passenger gets on the vehicle, the host starts, and the light position and color can be customized by voice control and host large screen software (the atmosphere lamp color can be red, orange, yellow, green, cyan, blue, purple, white, and 256 colors or more mixed colors). At the same time, if the vehicle owner allows the in-vehicle camera to operate, the in-vehicle camera identifies adults or children, and the child seat wears a seat belt. The light color defaults to the standard soft light (2700K to 4000K warm white light can be calibrated), which ensures that the eyes are not hurt. The light intensity can be preset to a fixed value, or it can be dynamically adjusted according to the actual environment light. The light of the adult position can be slightly bright. The main and vice drivers can realize the memory function, and the color preferred by the vehicle owner is defaulted. Other passengers can set through voice or APP software and in-vehicle APP software (the memory number is 100, and the default is covered when exceeded). The seat belt lock tongue inserted into the lock buckle can extinguish the light, or the voice can control the light to light the parts preferred by the driver.

[0038] After the driver starts the vehicle, all seat belt and seat system lights can also be extinguished or continuously lit.

[0039] The vehicle is stationary and the vehicle is in P gear, the light is turned on again, which is convenient for passengers to unlock the safety belt, and the light of the seat system is turned off after the passenger safety belt buckle is unlocked. The vehicle is turned off, and the light is turned off. If the vehicle is in N gear and the driver does not get off, the other passengers are unlocked, and the light of the seat system is turned off.

[0040] The vehicle can further be designed with a control button connected to the controller of the photovoltaic power generation device. The control button can be a mechanical button or a virtual button integrated into the central control screen. Under the condition of starting the host, the light safety belt and seat light can be set to move with the dashboard and door panel ambient light in the software, and move with the host music to display different colors.

[0041] The embodiment of the present disclosure further provides an interior lighting control method, comprising:

[0042] Obtain the interior light information, equipped with an ambient light sensor, and generate a first light signal according to the interior light information according to the brightness of the light;

[0043] Obtain the door opening state, and generate a second light signal according to the door opening state (ON / OFF);

[0044] Obtain the vehicle running state (ON / ACC / OFF), and generate a third light signal according to the vehicle running state;

[0045] Generate a fourth light signal in response to a user instruction;

[0046] According to the first light signal, the second light signal, the third light signal and the fourth light signal, control the light-emitting state and / or light intensity of the light-emitting safety belt system.

[0047] The interior light information can be obtained by the ambient light sensor arranged in the vehicle. When it is judged that the interior light intensity is lower than the set threshold value, for example, when the light intensity is lower than 10 lux, the first light signal is generated. The first light signal can be used to trigger the total switch signal of the light-emitting safety belt system. When the first light signal is received, it can be further judged whether to emit light according to other signals. In addition, the first light signal can further include the light-emitting brightness of the light-emitting safety belt system controlled according to the ambient light information. The corresponding relationship between the light-emitting brightness and the ambient light information can be pre-set, for example, for the controllable light-emitting material (LED lamp) arranged at the safety belt buckle, safety belt lock tongue, seat, etc. The light-emitting intensity L is controlled according to the formula L=K·ln(L0-L1+1), wherein K is a proportional coefficient (which can be set), L0 is an ambient light intensity threshold, and L1 is an ambient light intensity.

[0048] The door opening state can be obtained according to a door sensor, and when the door opening is detected, a light-emitting control signal of the corresponding area can be generated according to the door opening position to control the seat belt, lock buckle and seat light-emitting at the door.

[0049] The third light-emitting signal includes vehicle starting state, gear state, vehicle speed and other information. When the vehicle is not started, the light-emitting can be controlled, and when the driver starts the vehicle, all light-emitting structures can be extinguished at the same time to avoid affecting the driving safety. The gear state is the current gear of the vehicle, which can be combined with the vehicle starting state and the vehicle speed to control the light-emitting. In some embodiments, when it is judged that the vehicle is at rest and in P gear, the light is on, which is convenient for passengers to unfasten / fasten the safety belt; when it is judged that the vehicle is in a non-stationary state, the light is off. In other embodiments, a pressure sensor can be further designed at the vehicle seat, or an in-vehicle camera (after user authorization) is used to obtain whether there is a passenger at each seat, and when it is judged that there is no passenger in the vehicle, the light-emitting safety belt system at the corresponding seat does not emit light. At this time, the light-emitting intensity can be further controlled according to the state of the passenger getting on and off the vehicle. For example, when the driver's seat is empty and the driver opens the door, the light-emitting intensity is calculated according to L = K·ln(L0-L1+1), and when it is monitored that the driver is seated, for example, the pressure value (seat pressure) of the pressure sensor at the seat reaches the set threshold value, or the in-vehicle camera judges that there is a person in the driver's seat, the light-emitting intensity of the seat is reduced by a set value, for example, 80%, or is turned off, to reduce unnecessary light-emitting, the light-emitting intensity of the safety belt webbing is reduced by a set value, for example, 50%, to avoid the light-emitting being too dazzling to affect the driver's experience, and the light-emitting intensity of the safety belt lock tongue and the safety belt lock buckle is maintained, so as to facilitate the driver to quickly find the lock tongue and the lock buckle position and improve the experience of fastening the safety belt.

[0050] The fourth light-emitting signal is generated according to the user's button or voice instruction to meet the individual control demand.

[0051] The above only describes the preferred embodiments of the present disclosure and is not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
