[0021] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings, but it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present disclosure.

[0022] As a decorative lamp for a vehicle, the front grille light needs to meet the lighting needs of the lamp as well as the vehicle's styling and decoration needs. During the day, the grille light in a non-luminous state can have a variety of exterior colors to match the front bumper to meet the expression of vehicle styling and decoration; at night, the grille light in a luminous state needs a higher brightness to match other luminous parts at the front of the vehicle to meet the nighttime lighting brightness requirements of the vehicle. However, in reality, there is a certain conflict between the multi-color requirements and brightness requirements of the grille light.

[0023] In the related art, a multi-color mask is usually obtained by spraying a mask with colored paint to meet the daytime styling requirements, but the multi-color mask will reduce the transmittance of the light, which is generally reduced by about 50% compared with a transparent mask, thereby reducing the brightness of the grille lamp at night; or a transparent mask is directly used to meet the brightness requirements of the grille lamp at night but does not meet the multi-color styling requirements of the grille lamp during the day. How to simultaneously meet the lighting and styling requirements of the grille lamp has become a thorny problem to be solved.

[0024] In this regard, the present invention provides a color-changing grille lamp 100, comprising a mask 101 and a light-emitting unit 103 arranged at intervals; an electrochromic crystal-coated glass 102, arranged between the mask 101 and the light-emitting unit 103; wherein, when the light-emitting unit 103 is in a working state, the electrochromic crystal-coated glass 102 is in a power-off state, and the light beam emitted by the light-emitting unit 103 passes through the electrochromic crystal-coated glass 102 and then exits from the mask 101; when the light-emitting unit 103 is in a closed state, the electrochromic crystal-coated glass 102 is in a power-on state to change the color of the electrochromic crystal-coated glass 102 itself. In this way, an electrochromic glass 102 is added between the mask 101 and the light-emitting unit 103. When the light-emitting unit 103 is working, the electrochromic glass 102 is in a power-off state, so that the light beam emitted by the light-emitting unit 103 can be emitted from the mask 101, thereby meeting the lighting demand of the color-changing grille lamp 100. At the same time, when the light-emitting unit 103 is turned off, the electrochromic glass 102 is in a power-on state and can change its own color, thereby meeting the styling demand of the color-changing grille lamp 100, which to a certain extent solves the problem in the related art that the lighting demand and styling demand of the grille lamp cannot be met at the same time.

[0025] In addition, in the related art, electrochromic glass is also used as the grille light mask, which has the risk of being damaged by road gravel during driving, resulting in low reliability of the grille light. At the same time, the shape of the lampshade is relatively complex. Direct use of electrochromic glass makes glass production difficult and the pass rate is low, resulting in increased production costs of the glass, thereby increasing the cost of the entire lamp. However, the color-changing grille light 100 provided by the present invention sets the electrochromic crystal-coated glass 102 between the mask 101 and the light-emitting unit 103, which can not only meet the needs of the color-changing grille light 100 through the electrochromic crystal-coated glass 102, but also protect the electrochromic crystal-coated glass 102 through the mask 101, thereby improving the overall reliability of the color-changing grille light 100. Since the color-changing grille light 100 provided by the present invention does not perform additional processing on the mask 101, it can also save the cost of the lamp.

[0026] Additionally, in the color-changing grille lamp 100 provided by the present invention, an electrochromic crystal-coated glass 102 is disposed between the mask 101 and the light-emitting unit 103, replacing the inner lens in the original structure of the grille lamp, thereby reducing the production of one plastic part and saving the cost of parts and plastic molds. Since the electrochromic crystal-coated glass 102 is used to replace the inner lens, the transmittance of the light beam emitted by the light-emitting unit 103 can also be increased by about 50%, so the grille lamp can use lower-power light-emitting diode (LED) particles, reducing the cost of the printed circuit board (PCB) of the entire lamp and providing heat resistance for the entire lamp. Combined with the above beneficial effects, the color-changing grille lamp 100 provided by the embodiment of the present invention can achieve both the styling requirements and the lighting requirements of the grille lamp at a more economical cost.

[0027] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0028] Figure 1 This is a structural block diagram of the color-changing grille lamp provided by the present invention. Figure 1 As shown, the color-changing grille lamp 100 provided by the present invention includes a mask 101 and a light-emitting unit 103 that are arranged at intervals; and an electrochromic crystal-coated glass 102 is arranged between the mask 101 and the light-emitting unit 103 .

[0029] In the embodiment of the present invention, the mask 101 may be a common grille light mask on the market, and the embodiment of the present invention does not impose specific restrictions on the parameter characteristics of the mask 101, such as the size, shape, material, and light transmittance of the mask 101. Correspondingly, the light-emitting unit 103 may also be a common grille light PCB board on the market, and the embodiment of the present invention does not impose specific restrictions on the parameter characteristics of the light-emitting unit 103.

[0030] For example, the mask 101 may be circular, and inside the circular mask 101, the light emitting unit 103 may be a circular PCB board or a rectangular PCB board, and the light beam divergence range of the light emitting unit 103 may cover the entire mask, so that the shape of the light beam emitted by the color-changing grille lamp 100 is the shape of the mask 101. The mask 101 may also be an irregular arc shape so as to fit the vehicle body, and inside the irregular mask 101, the light emitting unit 103 may also be any shape.

[0031] In the embodiment of the present invention, the mask 101 and the light emitting unit 103 can be spaced apart, and the distance of the spaced apart setting can be randomly set according to actual conditions, and the embodiment of the present invention does not impose specific restrictions on this. After the mask 101 and the light emitting unit 103 are spaced apart, the electrochromic crystal-coated glass 102 can be set between the mask 101 and the light emitting unit 103, such as Figure 1 As shown in , the distance between the electrochromic glass 102 and the mask 101 or the light-emitting unit 103 can also be set according to actual conditions.

[0032] In the embodiment of the present invention, when the light-emitting unit 103 is in the working state, the electrochromic crystal-coated glass 102 is in the power-off state, and the light beam emitted by the light-emitting unit 103 passes through the electrochromic crystal-coated glass 102 and then exits from the mask 101. In this propagation process, since the electrochromic crystal-coated glass 102 is in the power-off state, it presents a transparent color, and the light beam emitted by the light-emitting unit 103 can be propagated to the maximum extent. At this time, the light beam emitted by the light-emitting unit 103 passes through the mask 101, thereby achieving the lighting requirement.

[0033] Accordingly, when the light-emitting unit 103 is in the off state, the electrochromic glass 102 is in the powered-on state to change the color of the electrochromic glass 102 itself. When the light-emitting unit 103 does not emit a light beam, the electrochromic glass 102 is in the powered-on state, and the color of the electrochromic glass 102 itself can be changed. At this time, the color of the electrochromic glass 102 after the change is transmitted through the mask 101, which can meet the multi-color styling requirements for the color-changing grille lamp 100. In the embodiment of the present invention, there is no specific restriction on the color of the electrochromic glass 102 after the change. That is to say, in the embodiment of the present invention, the electrochromic glass 102 can change to one color when it is powered on, or it can change to different colors or different brightness of the same color according to different power-on states. For example, currents of different voltages may be provided to the electrochromic coated glass 102 to make the electrochromic coated glass 102 present different colors, and different status signals may be provided to the electrochromic coated glass 102 to make the electrochromic coated glass 102 present different colors.

[0034] In this way, by changing the power-on state of the electrochromic crystal-coated glass 102, the mask 101 is a colored mask when the color-changing grille lamp 100 is not lit, and the mask 101 becomes transparent when it is lit, so that the color-changing grille lamp 100 provided by the present invention meets both the modeling requirements and the lighting requirements. At the same time, in the present invention, the mask 101 can be made of traditional plastic, and the stone-impact resistance is increased. The electrochromic crystal-coated glass 102 that realizes color change is at the rear of the mask 101, and the shape is simple, which improves the production qualification rate, and realizes the color change of the mask 101 of the color-changing grille lamp 100 in a more economical form.

[0035] Additionally, in the color-changing grille lamp 100 provided by the present invention, an electrochromic crystal-coated glass 102 is disposed between the mask 101 and the light-emitting unit 103, replacing the inner lens in the original structure of the grille lamp, thereby reducing the production of a plastic part and saving the cost of parts and plastic molds. Since the electrochromic crystal-coated glass 102 is used to replace the inner lens, the transmittance of the light beam emitted by the light-emitting unit 103 can also be increased by about 50%, so the color-changing grille lamp 100 provided by the present invention can use lower-power light-emitting diode (LED) particles, reducing the cost of the printed circuit board (PCB) of the entire lamp and providing heat resistance of the entire lamp.

[0036] In the embodiment of the present invention, in order to achieve the same effect, the electrochromic glass 102 may be replaced by other types of color-changing glass, such as photochromic glass, thermochromic glass, and mechanochromic glass.

[0037] In the color-changing grille lamp 100 provided in the embodiment of the present invention, Figure 2 As shown, the grille light controller 104 is included. The grille light controller 104 is used to be electrically connected to the vehicle controller 201 of the vehicle, and the grille light controller 104 is also connected to the circuit of the electrochromic crystal-coated glass 102.

[0038] In the embodiment of the present invention, the electrochromic coated glass 102 includes a glass body and a circuit capable of controlling the color change of the glass. For example, the electrochromic coated glass 102 may also include two connectors for displaying the positive and negative electrodes of the glass circuit, such as Figure 2 As shown, the connector of the electrochromic coated glass 102 is connected to the grille light controller 104 so that the grille light controller 104 can control the current of the electrochromic coated glass 102 , and further the vehicle controller 201 can control the power supply of the electrochromic coated glass 102 through the grille light controller 104 .

[0039] In an embodiment of the present invention, the grille light controller 104 can be electrically connected to the vehicle controller 201 of the vehicle so as to receive signal input and power input of the vehicle controller 201, wherein the signal input can be used to indicate the working status of the light-emitting unit 103 in the color-changing grille light 100, and the power input can be used to make the grille light controller 104 work, and can also be used to energize the electrochromic coated glass 102 through the grille light controller 104.

[0040] Specifically, in the embodiment of the present invention, the vehicle controller 204 can transmit a first control signal to the grille light controller 104, and the first control signal can be used to instruct to turn off the light-emitting unit 103 and to energize the electrochromic glass 102 to achieve the styling requirements of the color-changing grille light 100. In the embodiment of the present invention, there is no restriction on the specific form of the first control signal, which can be agreed upon by the grille light controller 104 and the vehicle controller 201. When the grille light controller 104 receives the first control signal transmitted by the vehicle controller 201, it controls the circuit of the electrochromic glass 102 to provide current to the body of the electrochromic glass 102, so that the body of the electrochromic glass 102 changes color, so that the color-changing grille light 100 as a whole shows the color of the electrochromic glass 102, and realizes the multi-color display of the color-changing grille light 100.

[0041] Accordingly, in the embodiment of the present invention, the vehicle controller 201 can also transmit a second control signal to the grille light controller 104, and the second control signal can be used to instruct to turn on the light-emitting unit 103 and cut off the current transmission of the electrochromic crystal-coated glass 102, so as to realize the lighting demand of the color-changing grille light 100. In the embodiment of the present invention, the specific form of the second control signal is not limited, and it can be agreed upon by the grille light controller 104 and the vehicle controller 201. When the grille light controller 104 receives the second control signal transmitted by the vehicle controller 104, it can control the light-emitting unit 103 to be in a working state, and prevent the vehicle controller 201 from inputting current to the electrochromic crystal-coated glass 102, cut off the current input of the electrochromic crystal-coated glass 102, so that the electrochromic crystal-coated glass 102 presents the color and transparency of the glass body, better transmits the light beam emitted by the light-emitting unit 103, and makes the color-changing grille light 100 pass through the light-emitting unit 103, so as to realize the lighting demand of the color-changing grille light 100.

[0042] In the embodiment of the present invention, the grille light controller 104 receives a signal from the vehicle controller 201 and switches between lighting requirements and styling requirements, thereby more accurately changing the state of the grille light.

[0043] In the color-changing grille lamp 100 provided in the embodiment of the present invention, Figure 3 As shown, the lamp housing 105 is included. The lamp housing 105 is disposed on a first side of the light emitting unit 103, and the first side is a side away from the electrochromic crystal-coated glass 102. The electrochromic crystal-coated glass 102 and the light emitting unit 103 are both fixed on the lamp housing 105, and the electrochromic crystal-coated glass 102 and the light emitting unit 103 can be fixed on the lamp housing 105 in sequence by means of screws, adhesion, or the like.

[0044] For example, the lamp housing 105 can be close to the vehicle body, and then the light-emitting unit 103 is fixed to the lamp housing 105 by means of screws, and then the electrochromic crystal-coated glass 102 is fixed to the lamp housing by means of screws. The electrochromic crystal-coated glass 102 will cover the light-emitting unit 103, so that the light beam emitted by the light-emitting unit 103 can pass through the electrochromic crystal-coated glass 102. While meeting the needs of the color-changing grille lamp 100, it can be more stable and improve the reliability of the color-changing grille lamp 100.

[0045] In the embodiment of the present invention, in order to better enable the mask 101 to meet the styling requirements and fully show the changed color of the electrochromic coated glass 102, the shape and size of the electrochromic coated glass 102 are basically consistent with the shape and size of the mask 101.

[0046] In the embodiment of the present invention, in order to make the light transmission and / or color transmission effect of the mask 101 better, and further make the brightness and / or color effect of the color-changing grille lamp 100 better displayed, the material of the mask 101 is transparent polymethyl methacrylate (PMMA) or polycarbonate (PC). At the same time, the spraying of colored paint inside the multi-color mask can be reduced, thereby making the production process of the color-changing grille lamp 100 more environmentally friendly and low-cost.

[0047] In an embodiment of the present invention, there is also provided a Figure 4 The vehicle lighting system shown includes: Figure 2 The color-changing grille lamp 100 ( Figure 4 This is just an example. The vehicle light system provided by the embodiment of the present invention may also include the following Figure 3 The color-changing grille light 100 shown in the figure); a central control light switch 202 and a light sensor 203; a vehicle controller 201, which is connected to the grille light controller 104 of the color-changing grille light 100, the central control light switch 202 and the light sensor 203, so that the vehicle controller 201 receives the instructions of the central control light switch 202 and the values ​​detected by the light sensor 203.

[0048] In the embodiment of the present invention, the vehicle controller 201 can perform logic judgment before inputting a control signal to the grille light controller 104, and the signal of the logic judgment is input by the light sensor 203 and the central control light switch 202. That is, the vehicle controller 201 can output the first control signal or the second control signal to the grille light controller 104 according to whether the central control light switch 202 has a user's lighting operation for the grille light and the illumination value of the external environment detected by the light sensor 203.

[0049] Specifically, the central control light switch 202 can be set on the center console of the vehicle. The central control light switch 202 can be in the form of a physical button or a virtual button on the central control display screen of the vehicle, and the switch operation of the light can be realized through the circuit of the central control display screen. The central control light switch 202 can be used to accept manual lighting operation on the color-changing grille light 100. For example, when a user presses the central control light switch 100, it can indicate lighting the color-changing grille light 100. The vehicle controller 104 can output a second control signal to the grille light controller 104 to light up the light-emitting unit 103 and cut off the electrochromic crystal-plated glass circuit 102 based on the user operation transmitted by the central control light switch 100.

[0050] The light sensor 203 can be arranged outside the vehicle to detect the illumination value of the external environment and transmit it to the vehicle controller 201 in real time. The vehicle controller 201 can judge whether to turn on the color-changing grille light 100 according to the preset threshold value based on the illumination value of the external environment detected by the light sensor 201, thereby determining the control signal output to the grille light controller 104. For example, when the illumination value of the external environment is greater than 3500lx, the vehicle controller 201 can consider that the external environment is brighter and it is daytime, and can output to the grille light controller 104 a first control signal to turn off the light-emitting unit 103 and energize the electrochromic crystal-coated glass 102 to change the color of the color-changing grille light 100. Through the central control light switch 202 and the light sensor 203, the control signal output by the vehicle controller 201 can be made more accurate, thereby enabling the color-changing grille light 100 to switch between the two needs more intelligently.

[0051] In an embodiment of the present invention, the vehicle controller 201 can also determine whether to output the first control signal or the second control signal to the grille light controller 104 based on whether the user has turned on the color-changing grille light 100 on the central control light switch 202, and the illumination value of the external environment detected by the light sensor 203.

[0052] In an embodiment of the present invention, if the illumination value of the external environment is greater than or equal to the first threshold value, and there is no user operation on the central control light switch 202, a first control signal is output to the grille light controller 104; if the illumination value of the external environment is less than or equal to the second threshold value, or there is user operation on the central control light switch 202, a second control signal is output to the grille light controller 104.

[0053] In the embodiment of the present invention, the first threshold value and / or the second threshold value for judgment can be preset in advance for the illumination value of the vehicle exterior environment detected by the light sensor 203. The magnitude of the first threshold value and / or the second threshold value can be judged based on manual experience, or can be intelligently judged through a machine learning model, and the embodiment of the present invention does not impose specific restrictions. Preferably, the first threshold value can be 3500 lx, and the second threshold value can be 1500 lx.

[0054] In the embodiment of the present invention, when the light sensor 203 detects that the illumination value of the external environment is greater than or equal to 3500 lx (i.e., the first threshold), the illumination value of the external environment can be transmitted to the vehicle controller 201, and the vehicle controller 201 simultaneously determines whether there is a user operation on the central control light switch 202, that is, whether there is a signal input from the central control light switch 202 to the vehicle controller 201. If there is no signal input from the central control light switch 202, the vehicle controller 201 can logically determine that it is daytime and output a first control signal to the grille light controller 104. The grille light controller 104 energizes the electrochromic crystal-coated glass 102, and the electrochromic crystal-coated glass 102 changes color after being energized, so as to achieve the appearance effect required by the shape of the color-changing grille light 100. If there is a signal from the central control light switch 202, the vehicle controller 104 can determine that it is a special need of the user, and can output a second control signal to the grille light controller 104, turn on the light-emitting unit 103 in the color-changing grille light 100, and light up the color-changing grille light 100.

[0055] In an embodiment of the present invention, when the light sensor 203 detects that the illumination value of the external environment is less than or equal to 1500Lx (the second threshold), or there is a user operation on the central control light switch 202 (which can also be understood as the central control development 202 is turned to the position light state), the vehicle controller 201 can output a second control signal to the grille light controller 104, and the grille light controller 104 cuts off the power supply to the electrochromic coated glass 102, and the electrochromic coated glass 102 turns to a transparent color. At the same time, the grille light controller 104 controls the light-emitting unit 103 to work and light up, thereby achieving the lighting brightness requirement of the color-changing grille light 100.

[0056] In an embodiment of the present invention, if the external environment illumination value is greater than the second threshold and less than the first threshold, the vehicle controller 201 may also output the first control signal or the second control signal to the grille light controller 104 according to whether the vehicle headlights are in working state.

[0057] In the embodiment of the present invention, the vehicle headlights can also be understood as vehicle front lights, indicating the vehicle headlight system. When the illumination value of the external environment detected by the light sensor 203 is between the second threshold and the first threshold, the vehicle controller 201 can determine the signal to be output to the grille light controller 104 according to the state of the vehicle headlights. For example, when the illumination value of the external environment detected by the light sensor 203 is between the second threshold and the first threshold, but the vehicle headlights are in the working state, the vehicle controller 201 can output a second control signal to the grille light controller 104, so that the grille light controller 104 lights up the light-emitting unit 103, cuts off the current input of the electrochromic crystal-coated glass 102, and presents the working state together with the vehicle headlights to meet the lighting needs of the user. It can not only conveniently realize the requirements of the multi-color mask of the color-changing grille light 100, but also ensure the consistency of the brightness of the lighting system.

[0058] In the embodiment of the present invention, whether the vehicle headlights are in working state can be determined by the vehicle controller 104 according to other parameters, which will not be elaborated in the present invention.

[0059] An embodiment of the present invention also provides a control method for a color-changing grille lamp 100, which is applied to the vehicle lighting system described above, and the method includes: detecting whether a user has performed a lighting operation on the color-changing grille lamp 100, and obtaining the illumination value of the external environment detected by the light sensor 203; outputting a first control signal or a second control signal to a grille lamp controller 104 according to whether a user has performed a lighting operation on the color-changing grille lamp 100, and the illumination value of the external environment detected by the light sensor 203.

[0060] It should be noted that the embodiment of the control method of the color-changing grille lamp 100 in this specification and the embodiment of the vehicle lamp system in this specification are based on the same inventive concept, so the specific implementation method can refer to the corresponding embodiment of the vehicle lamp system in the previous text, and the repeated parts will not be repeated. Through the control method provided in the embodiment of the present invention, the brightness and color of the color-changing grille lamp 100 can be intelligently controlled, so that the color-changing grille lamp 100 can meet both lighting requirements and styling requirements.

[0061] An embodiment of the present invention further provides a complete vehicle, comprising: a vehicle body; and a vehicle light system, which is arranged on the vehicle body, and the vehicle light system is the vehicle light system described above.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
