The vehicle-mounted atmosphere light has a simple overall structure, low cost, and can convert the light of a single light source into a gorgeous spiral light band, achieving a good artistic lighting effect and giving users a good experience. This technical solution uses a single light to solve the problem in reference document 1 that it generates a large amount of heat and has potential safety hazards, but the single light is attenuated in the light rotation module, the intensity of the light of the rear section of the light strip cannot be guaranteed, and the atmosphere light only serves a decorative purpose. Summary of the invention

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: It includes a light-emitting source. A light guide bar is provided at the output end of the light-emitting source. A sub-controller for controlling the light-emitting source is provided on the light-emitting source. The sub-controller is respectively connected with a power supply line and a signal line. The light-emitting source is at least divided into an instrument panel part, an interior left part, and an interior right part. The sub-controller is aggregated with the main controller through the signal line. The main controller collects vehicle information and an active control signal, and the power supply line takes power nearby.

[0007] Preferably, the light-emitting source includes a heat dissipation substrate installed inside the sub-controller. A three-color lamp bead controlled by the sub-controller is provided on the surface of the heat dissipation substrate. A reflecting bowl is provided outside the three-color lamp bead. A light guide connection part connected to the light guide bar is provided inside the reflecting bowl.

[0008] The light guide bar includes an optical fiber and a diverging layer covering the outer surface of the optical fiber. A connection part for connecting with the vehicle is provided on the back of the diverging layer.

[0009] Preferably, the connection part includes an adhesive part connected to the diverging layer. An adhesive layer composed of an adhesive is provided on the side of the adhesive part away from the diverging layer.

[0010] Preferably, the connection part includes a clamping strip connected to the diverging layer. An "eight"-shaped protrusion is formed at the end of the clamping strip away from the diverging layer. The total thickness is less than the thickness of the clamping strip when the protrusions are in contact with each other.

[0011] Preferably, a light-shielding layer is provided on the outer surface of the diverging layer near the light-emitting source side and at one end away from the light-emitting source.

[0012] A control method for a vehicle-mounted atmosphere lamp includes the following steps: S1. The main controller collects vehicle operation signals and active control signals; S2. The collected vehicle operation signals are divided into high-priority safety information and low-priority entertainment information; S3. The main controller converts the collected signals into electrical signals and respectively transmits them to the sub-controller 3 to control the light-emitting source 1 to emit a specified light effect.

[0013] Preferably, when a safety information is collected during the playback of the light effect corresponding to the entertainment information, the light effect corresponding to the safety information is preferentially played; The light effect at least includes color transformation, brightness transformation, and flicker frequency transformation; When the light effect corresponding to the safety information is switched, at least one parameter is significantly different from the light effect corresponding to the entertainment information.

[0014] Preferably, the safety information in step S2 includes active adjustment safety information and passive trigger safety information; The active adjustment safety information at least includes vehicle tire pressure display and vehicle navigation information; The passive trigger safety information at least includes information about oncoming vehicles from behind, vehicle failure information, and front and rear collision reminder information.

[0015] Preferably, the entertainment information in step S2 at least includes static light display information, music rhythm information, and sports mode switching information.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. For this in-vehicle atmosphere lamp, a light guide bar is provided at the output end of the light source, and a sub-controller for controlling the light source is provided for the light source. The light source is at least divided into an instrument panel part, an interior left part, and an interior right part. The sub-controllers are respectively connected with a power supply line and a signal line, and the sub-controllers are aggregated with the main controller through the signal line. By separately arranging the signal line and the power supply line and taking power nearby for the power supply line, the laying of the power supply line can be reduced, and at the same time, the brightness of the light guide bar can be ensured.

[0017] 2. For this method for controlling an in-vehicle atmosphere lamp, the main controller collects vehicle operation signals and active control signals, divides the collected vehicle operation signals into high-priority safety information and low-priority entertainment information, and the main controller converts the collected signals into electrical signals and respectively transmits them to the sub-controllers to control the light source to emit a specified light effect, so as to be able to display lights that assist vehicle safety, thereby ensuring driving safety.

[0018] 3. For this in-vehicle atmosphere lamp, a reflective bowl is provided outside the three-color lamp beads. The three-color lamp beads are three colors: red, green, and blue. Since the light emitted by the three-color lamp beads is relatively scattered, by providing the reflective bowl, the light can be aggregated and emitted in a specified direction. A light guide connection part connected to the light guide bar is provided inside the reflective bowl. The shape of the light guide connection part is conical, and the outer surface is covered by the reflective bowl. Since the light spot reflected by the reflective bowl is relatively large, by providing the light guide connection part, the light of the entire light spot is aggregated into the light guide bar.

[0019] 4. For this in-vehicle atmosphere lamp, the connecting part is provided with a clamping strip connected to the divergence layer. By inserting the clamping strip into a specified gap, the light guide bar can be fixed by the friction between the clamping strip and the gap. An "eight"-shaped protrusion is formed at the part of the clamping strip away from the divergence layer. When the protrusions contact each other, the total thickness is less than the thickness of the clamping strip. The protrusions are provided to increase the friction with the gap through the elastic deformation of the protrusions when the connecting part is inserted into the gap, thereby being able to fix the light guide bar.

[0020] 5. For the in-vehicle ambient light control method, when collecting safety information while playing the light effect corresponding to entertainment information, the light effect corresponding to the safety information is given priority for playback. Generally, when a vehicle is in a normal driving state, only the light effect corresponding to entertainment information is displayed. However, the safety information has a higher priority, and at least one parameter of the light effect corresponding to the safety information is significantly different from the light effect corresponding to the entertainment information. For example, when the light effect of the entertainment information happens to play a blue light effect and suddenly safety information is collected, a red flashing signal is played at this time to give a reminder, and then the light effect corresponding to the corresponding safety information is displayed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0024] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0025] In this application, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] In addition, in this application, descriptions such as "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0027] As Figures 1-4 shown, a vehicle-mounted atmosphere lamp includes a light source 1. A light guide bar 2 is arranged at the output end of the light source 1. A sub-controller 3 for controlling the light source 1 is arranged on the light source 1. The light source 1 is at least divided into an instrument panel part, an interior left part, and an interior right part. The original single light source 1 is connected to a long light guide bar 2 for overall light control. The light attenuation of the long-distance light guide bar 2 is relatively obvious. By dispersing the light source 1, the number of light sources 1 is increased, so as to ensure the light-emitting brightness of the light guide bar 2.

[0028] Because there is significant light attenuation in the original method (a single light source 1 is connected to a long light guide bar 2 for overall light control), the light source 1 is at least dispersed into an instrument panel part, an interior left part, and a right part, and the number of light sources 1 is increased, thereby ensuring the light-emitting brightness of the light guide bar 2.

[0029] The sub-controller 3 is respectively connected with a power supply line 4 and a signal line 5. The sub-controller 3 is aggregated with the main controller 6 through the signal line 5. The main controller 6 collects vehicle information and active control signals, and the power supply line 4 takes power nearby. By separately arranging the signal line 5 and the power supply line 4 and arranging the power supply line 4 to take power nearby, the layout of the power supply line 4 can be reduced. By connecting the sub-controller 3 to the main controller 6 through the signal line 5 for overall control, setting such a secondary control method can reduce the connectors directly connected to the vehicle computer and can arrange the device more flexibly. For example, the main controller 6 is directly installed at the same position as the vehicle computer, and the signal line 5 is connected to the main controller 6 through a wire harness. In this way, the main controller 6 can be set at a specific position, avoiding the influence on aesthetics caused by external installation.

[0030] The master controller 6 collects vehicle information and active control signals, and the power supply wire 4 takes power nearby. The signal wire 5 is set separately from the power supply wire 4, and the power supply wire 4 taking power nearby can reduce the layout of the power supply wire 4. The signal wire 5 is used to connect the sub - controller 3 and the master controller 6 to achieve overall control. This secondary control method can reduce the joints directly connected to the vehicle computer, making the device layout more flexible. For example, the master controller 6 and the vehicle computer can be installed at the same position to avoid external influence on aesthetics.

[0031] The light source 1 includes a heat - dissipation substrate 101 installed inside the sub - controller 3. The surface of the heat - dissipation substrate 101 is provided with three - color lamp beads 102 controlled by the sub - controller 3. The sub - controller 3 controls the voltage of each color of lamp beads in the three - color lamp beads 102 to make the luminous brightness of each color different, so as to be able to mix into light of a specified color. At the same time, by setting different time and disconnection time frequencies for the overall power - on of the three - color lamp beads 102, the three - color lamp beads 102 are made to emit flashes according to a specified frequency.

[0032] The light source 1 contains a heat - dissipation substrate 101 installed inside the sub - controller 3, and its surface is provided with three - color lamp beads 102 controlled by the sub - controller 3. The sub - controller 3 regulates the voltage of each color of lamp beads in the three - color lamp beads 102 to make the luminous brightness of each color different for mixing into light of a specified color; at the same time, by setting the time and disconnection time frequencies of the overall power - on and power - off of the three - color lamp beads 102, it realizes flashing at a specified frequency.

[0033] A reflecting bowl 103 is arranged outside the three - color lamp beads 102. The three - color lamp beads 102 are of three colors: red, green, and blue. Since the light emitted by the three - color lamp beads 102 is relatively scattered, by setting the reflecting bowl 103, the light can be aggregated and emitted in a specified direction. A light - guiding connection part 104 connected to the light - guiding bar 2 is arranged inside the reflecting bowl 103. The shape of the light - guiding connection part 104 is conical, and its outer surface is covered by the reflecting bowl 103. Since the light spot reflected by the reflecting bowl 103 is relatively large, by setting the light - guiding connection part 104, the light of the entire light spot is aggregated into the inside of the light - guiding bar 2.

[0034] The three - color lamp beads 102 (red, green, and blue) emit light dispersedly. A reflecting bowl 103 is arranged outside it, which can aggregate the light and emit it in a specified direction; and because the light spot reflected by the reflecting bowl 103 is relatively large, a conical light - guiding connection part 104 is arranged inside it, whose outer surface is covered by the reflecting bowl 103, and the light of the light spot can be further aggregated into the inside of the light - guiding bar 2.

[0035] The light guide bar 2 includes an optical fiber 201 which is used for the transmission of the entire optical path. However, the light-emitting area is small. Therefore, a diverging layer 202 covering the outer surface of the optical fiber 201 is provided. Through the diverging layer 202, the display area of the light can be enlarged. Considering that the light guide bar 2 needs to be connected to the vehicle, a connecting portion 23 for connecting to the vehicle is provided on the back of the diverging layer 202.

[0036] The optical fiber 201 in the light guide bar 2 is used for the transmission of the optical path, but the light-emitting area is small. Therefore, a diverging layer 202 is provided on the outer surface of the optical fiber 201 to enlarge the display area of the light. Also, because the light guide bar 2 needs to be connected to the vehicle, a connecting portion 23 is provided on the back of the diverging layer 202 to realize the connection with the vehicle.

[0037] The connecting portion 23 includes an adhesive portion 231 connected to the diverging layer 202. The setting of the adhesive portion 231 can increase the contact area with the vehicle, so as to better connect with the vehicle. On the side of the adhesive portion 231 away from the diverging layer 202, there is an adhesive layer 232 composed of an adhesive. Before use, the surface of the adhesive layer 232 is covered with a protective layer. When it is necessary to bond the light guide bar 2 to the vehicle, the protective layer is removed, and the light guide bar 2 is fixed by pressing and bonding with the vehicle using the adhesive layer 232.

[0038] Generally, the light guide bar 2 needs to be snap-fitted into a specified gap of the vehicle. Therefore, the connecting portion 23 is provided to include a snap-fit bar 233 connected to the diverging layer 202. The snap-fit bar 233 is inserted into the specified gap, and the light guide bar 2 can be fixed through the friction between the snap-fit bar 233 and the gap. On the side of the snap-fit bar 233 away from the diverging layer 202, an "eight"-shaped protrusion 234 is formed. When the protrusions 234 are in contact with each other, the total thickness is less than the thickness of the snap-fit bar 233. The setting of the protrusions 234 can increase the friction with the gap through the elastic deformation of the protrusions 234 when the connecting portion 23 is inserted into the gap, so as to realize the fixation of the light guide bar 2.

[0039] A light-shielding layer 204 is provided on the outer surface of the diverging layer 202 close to the light source 1 and at one end away from the light source 1. The setting of the light-shielding layer 204 can prevent light leakage. Setting the light-shielding layer 204 at one end away from the light source 1 can prevent the light from irradiating outward. The reason for setting the light-shielding layer 204 on the outer surface of the diverging layer 202 close to the light source 1 is that during the installation process, part of the diverging layer 202 needs to bypass some positions that do not need to emit light. For example, when the light source 1 is arranged inside the interior trim panel, the diverging layer 202 needs to pass through and be snap-fitted into the corresponding gap. If the diverging layer 202 located inside is not subjected to light-shielding treatment, it will emit light inside and is likely to leak light from the gap of the interior trim panel, affecting the appearance. The light-shielding layer 204 is a black covering layer, and for the sake of beauty, the light-shielding layer 204 exposed inside the vehicle can be painted.

[0040] A light-shielding layer 204 is provided on the outer surface of the divergence layer 202 near one side of the light source 1 and at one end far from the light source 1 to avoid light leakage. Providing the light-shielding layer 204 at one end far from the light source 1 can prevent light from irradiating outward; providing the light-shielding layer 204 on the outer surface near one side of the light source 1 is because when installing, part of the divergence layer 202 needs to bypass the positions that do not need to emit light (for example, if the light source 1 is provided inside the interior trim panel, the divergence layer 202 needs to pass through and be clamped at the corresponding gap). If the internal divergence layer 202 is not light-shielded, it will emit light inside and leak light from the gap of the interior trim panel, affecting the aesthetics. The light-shielding layer 204 adopts a black covering layer, and for aesthetics, the part exposed inside the vehicle can be painted.

[0041] The vehicle-mounted atmosphere lamp includes the following control methods: S1. The total controller 6 collects vehicle operation signals and active control signals. When the vehicle operation signals are collected from the vehicle computer, and the vehicle computer drives the corresponding actuator to execute through the signals generated by the sensor or the control panel, the signals are synchronously transmitted to the total controller 6. The active control signal is the signal for controlling the light effect of the light source 1, and the generation methods thereof include at least the vehicle control terminal and the mobile control terminal, such as the atmosphere lamp adjustment system integrated on the vehicle control panel and the atmosphere lamp adjustment system on the mobile phone side; S2. The collected vehicle operation signals are divided into high-priority safety information. This type of information generally comes from various sensor information processed by the vehicle computer. The safety information includes active adjustment safety information and passive trigger safety information; The active adjustment safety information includes at least vehicle tire pressure display and vehicle navigation information. The active adjustment safety information needs to meet two characteristics. One is that it can be actively adjusted to the display mode, and the other is that the display content has an impact on driving safety. For example, when switching to the tire pressure display, based on the display brightness of the light source 1 on the previous instrument panel, the four light sources 1 corresponding to the doors are used to express different tire pressures through different display brightnesses. For example, when monitoring the vehicle speed during vehicle navigation, the flashing frequency of the light source 1 is reduced according to the increase in vehicle speed, and when the vehicle is speeding, the color of the light source 1 can be changed; The passive trigger safety information includes at least information about vehicles coming from behind. The original reminder for vehicles coming from behind is set to be displayed on the rearview mirror. While sending a signal to the rearview mirror, the total controller 6 controls the light source 1 to emit light and change. Vehicle fault information generally means that the sensor collects an abnormality, and the abnormal information is displayed through the instrument panel. At the same time, the corresponding light effect is displayed according to the alarm information. Front and rear collision reminder information. The front and rear collision information comes from the front and rear radars, and the decreasing flashing frequency of the light source 1 indicates that the vehicle is getting closer.

[0042] And low-priority entertainment information. The entertainment information includes at least static light display information, music rhythm information, and sports mode switching information. This part of the information has no impact on driving safety and plays a role in decoration, entertainment, and aesthetics.

[0043] S3. The master controller 6 converts the collected signals into electrical signals and transmits them to the sub - controllers 3 respectively to control the light source 1 to emit the specified light effects.

[0044] When the safety information is collected while playing the light effects corresponding to the entertainment information in step S3, the light effects corresponding to the safety information are played preferentially. Generally, when the vehicle is in a normal driving state, only the light effects corresponding to the entertainment information are displayed. However, the priority of the safety information is higher. Therefore, it is necessary to temporarily cut off the playback of the light effects corresponding to the entertainment information and play the light effects corresponding to the safety information. The light effects at least include the transformation of color, brightness, and blinking frequency. Through the combination of concentrated transformations, the corresponding information can be displayed. When the light effects corresponding to the safety information are switched, at least one parameter is significantly different from the light effects corresponding to the entertainment information. For example, when the light effect of the entertainment information happens to play a blue light effect and the safety information is suddenly collected, a red blinking signal is played at this time to remind, and then the light effects corresponding to the corresponding safety information are displayed.
