Description
Technical Field
[0001] This invention relates to the field of automotive lighting technology, specifically to a B-pillar backlight with intelligent sensing function. Background Technology
[0002] The B-pillar of a car refers to the area between the front and rear doors. The main function of the B-pillar is to withstand impact forces from the side, which can fully ensure the safety of the driver and passengers, while also supporting the overall vehicle structure.
[0003] However, the current B-pillar of a car has a single purpose and has great potential for further development. Currently, the main exterior lights of a vehicle include headlights, taillights, turn signals, fog lights, side marker lights, and reversing lights, all of which have fixed installation positions and play an irreplaceable role in actual use. The side marker lights, also known as side lights, are installed on the side of the vehicle to improve side visibility at night and in low visibility conditions.
[0004] For example, Chinese patent CN113291381A discloses a car B-pillar reinforcement structure and a car B-pillar, including a B-pillar reinforcement plate, a B-pillar upper beam and several first support plates. The B-pillar upper beam is connected to the top of the B-pillar reinforcement plate. The first support plates are assembled in the cavity of the B-pillar upper beam, and each of the first support plates, the B-pillar upper beam and the B-pillar reinforcement plate together form a triangular stabilizing structure for improving the roof pressure value in the area where the B-pillar upper beam and the B-pillar reinforcement plate are connected.
[0005] As with the B-pillar of the car disclosed in the aforementioned patent, although the structural strength of the B-pillar has been strengthened, the function of the B-pillar is limited and there is much room for improvement.
[0006] Therefore, a device is needed that can expand the uses of the B-pillar. Summary of the Invention
[0007] The purpose of this invention is to provide a car B-pillar backlight with intelligent sensing function to solve the technical problem of the single use of existing car B-pillars mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution:
[0009] A car B-pillar backlight with intelligent sensing function includes: a first light-emitting panel, which is installed on the outer wall of the B-pillar. The first light-emitting panel is connected to a PCB board. The PCB board is provided with an intelligent sensing module and an intelligent monitoring module.

The signal input circuit, the voice receiving circuit, and the relay are all electrically connected to the control circuit. The intelligent sensing module, the voice receiving circuit, and the relay cooperate with the control circuit to turn the electrical connection of the first light-emitting panel on and off.
[0010] Preferably, the first light-emitting panel further includes a button panel, which includes a voice receiver and physical buttons.

[0015] Preferably, it also includes a second light-emitting panel, which includes an inner light panel and a color gradient panel. The inner light panel is disposed on the outer wall of the B-pillar, and the color gradient panel is disposed on the side of the inner light panel away from the B-pillar. The inner light panel is electrically connected to the intelligent monitoring module, and the second light-emitting panel and the first light-emitting panel are disposed at intervals on the outer wall of the B-pillar.
[0016] Preferably, the intelligent monitoring module includes a radar detection circuit and a switching circuit. The radar detection circuit and the switching circuit are electrically connected to the PCB board. The radar detection circuit is electrically connected to a radar detector. Two sets of radar detectors are provided, and the two sets of radar detectors are installed on the two B-pillars of the vehicle body. The switching circuit is electrically connected to the inner light panel.
[0017] Preferably, the PCB board is also electrically connected to a temperature sensor. Multiple temperature sensors are provided and installed inside the vehicle body. The temperature sensors, in conjunction with the PCB board, are used to monitor the temperature inside the vehicle body and adjust the brightness of the interior light panel.
[0018] The temperature sensor, in conjunction with the PCB board, is used to monitor the temperature inside the vehicle and adjust the brightness of the interior light panel, including:
[0019] A sensor location distribution matrix was constructed based on the placement of temperature sensors within the vehicle body.
[0020] Based on the real-time temperature values at corresponding locations within the vehicle body and the sensor location distribution matrix obtained in real time by all temperature sensors, a real-time temperature distribution matrix within the vehicle body is constructed.
[0021] The system acquires real-time solar radiation data of the vehicle's current location. Based on the real-time solar radiation data and the vehicle's three-dimensional shape model, it generates a solar radiation-induced temperature rise matrix inside the vehicle body. The solar radiation-induced temperature rise matrix and the real-time temperature distribution matrix are identical matrices.
[0022] The product of the reduced weighting of the solar radiation temperature determination and the solar radiation-induced temperature rise matrix is used as the pseudo temperature rise matrix inside the vehicle body.
[0023] Subtract the real-time temperature distribution matrix and the pseudo temperature rise matrix inside the vehicle body to obtain the vehicle body temperature determination matrix.
[0024] If the temperature determination matrix contains an element that is not less than the temperature threshold, a high temperature warning signal is generated. Based on the high temperature warning signal, a warning reminder is issued on the APP monitoring program on the smart mobile terminal. The location of the temperature sensor corresponding to the element in the temperature determination matrix that is not less than the temperature threshold is displayed on the APP monitoring program. At the same time, the second light panel is controlled to flash as a reminder.

[0028] Based on the temperature influence range of each location point on the outer surface of the vehicle, the temperature influence range of each temperature sensor's installation location is determined.
[0029] Based on the location of the temperature sensor and the local heat conduction attenuation coefficient and conduction distance between the location points corresponding to each temperature influence range, the temperature rise value of all solar radiation influence at the location of the temperature sensor is calculated.
[0030] A solar radiation-induced temperature rise matrix is constructed based on the sum of all solar radiation-induced temperature rise values at the locations of each temperature sensor inside the vehicle.
[0031] Compared with the prior art, the beneficial effects of the present invention are:
[0032] This invention provides a car B-pillar backlight with intelligent sensing function, comprising: a first light-emitting panel, the first light-emitting panel being installed on the outer wall of the B-pillar, the first light-emitting panel being connected to a PCB board, the PCB board being provided with an intelligent sensing module and an intelligent monitoring module, the intelligent sensing module including a control circuit, a signal input circuit, a voice receiving circuit, and a relay, the signal input circuit, the voice receiving circuit, and the relay being electrically connected to the control circuit, the intelligent sensing module, the voice receiving circuit, and the relay cooperating with the control circuit to turn the electrical connection of the first light-emitting panel on and off;
[0033] The system receives signals through an intelligent sensing module. The PCB board identifies the received signals and controls the opening and closing of the first light panel. The B-pillar backlight is used to control the opening and closing of the first light panel via voice when illumination is needed, making it more convenient and facilitating quick activation in low-light conditions at night. The intelligent monitoring module monitors the in-vehicle environment and sends the monitored data to the PCB board. The PCB board controls the display of the first light panel, which provides illumination, quickly illuminating the vehicle when approaching at night. It can also display patterns for illuminated decorations and advertising. The intelligent monitoring module can monitor the interior temperature of the vehicle. In summer, when the vehicle is parked without sunshades, the interior temperature rises. Incidents of spontaneous combustion due to excessively high interior temperatures are rare. The interior temperature is displayed on the first light panel and sent to a smart mobile terminal, allowing users to monitor the interior temperature in real time and observe it directly through the first light panel.
[0034] By utilizing the microprocessor within the PCB board in conjunction with radar detectors, targeted alerts are provided for pedestrians or vehicles encountered by the car during its journey, as well as during reversing, parallel parking, parking in a parking space, high-speed driving, driving on curves, and driving on frequently traveled roads. This expands the scope of intelligent alerts, improves their quality, and contributes to safe driving for car drivers, effectively ensuring vehicle safety.
[0035] Based on the real-time temperature distribution matrix and the solar radiation-induced temperature rise matrix inside the vehicle, and combined with the solar radiation temperature determination mitigation weight, a vehicle body temperature determination matrix is obtained that can be used to determine whether the temperature inside the vehicle has reached the temperature threshold that requires tightening. Based on this determination method, not only is the real-time temperature of various parts inside the vehicle taken into account, but the influence of solar radiation on the real-time temperature of the vehicle body is also eliminated. Based on this determination result, a high temperature towel warning and a flashing control of the second light panel are implemented to avoid excessive warnings caused by the false temperature rise caused by solar radiation data to the temperature sensor. This improves the utilization efficiency of the second light panel and enhances the intelligent monitoring level of the vehicle's interior temperature.
[0036] Based on the solar radiation simulation results obtained from solar radiation data and the 3D model of the vehicle, the solar radiation temperature rise value at the location point on the outer surface of the vehicle was determined. Then, using the conduction attenuation calculation process, the solar radiation temperature rise value caused by the solar radiation temperature rise data on the outer surface of the vehicle to the temperature at the temperature sensor setting location was calculated, thereby accurately constructing the solar radiation temperature rise data inside the vehicle.

The inner light panel is disposed on the outer wall of the B-pillar, and the color gradient panel is disposed on the side of the inner light panel away from the B-pillar. The inner light panel is electrically connected to the intelligent monitoring module. The second light-emitting panel 2 and the first light-emitting panel 1 are disposed at intervals on the outer wall of the B-pillar.
[0067] In the above embodiment, the inner light panel is used to illuminate the color gradient panel by turning it on and off. The second light panel 2 has a warning function by flashing at different frequencies. At the same time, the color gradient panel can display different colors by changing the illuminated area of the inner light panel.
[0068] Example 8
[0069] like Figure 1-6 As shown, the intelligent monitoring module includes a radar detection circuit and a switching circuit. The radar detection circuit and the switching circuit are electrically connected to the PCB board. The radar detection circuit is electrically connected to the radar detector. There are two sets of radar detectors, which are installed on the two B-pillars of the vehicle body. The switching circuit is electrically connected to the inner light board.
[0070] The PCB board contains a microprocessor, and the radar detector is connected to the microprocessor.

[0076] Example 9
[0077] like Figure 1-6 As shown, the PCB board is also electrically connected to a temperature sensor. Multiple temperature sensors are provided and installed inside the vehicle body. The temperature sensors, in conjunction with the PCB board, are used to monitor the temperature inside the vehicle body and adjust the brightness of the second light-emitting panel 2.
[0078] A sensor location distribution matrix is constructed based on the placement of temperature sensors within the vehicle body. This involves dividing the temperature sensors within the vehicle body into rows and columns, using the maximum total number of rows obtained after row division and the maximum total number of columns obtained after column division as the row and column capacities of the sensor location distribution matrix (i.e., the total number of elements in each row and the total number of elements in each column of the matrix). The element positions corresponding to the temperature sensors in the sensor location distribution matrix are determined based on their placement locations and then matched (i.e., the identifier corresponding to each temperature sensor is filled into the corresponding element position in the corresponding sensor location distribution matrix). Additionally, when there are elements in the sensor location distribution matrix that do not correspond to a temperature sensor placement location, these elements are set to 0 (e.g., if the row capacity is 100 and the total row capacity in the row division result is 99, then the last element in that row is 0).
[0079] Based on the real-time temperature values at corresponding locations within the vehicle body and the sensor location distribution matrix obtained in real time by all temperature sensors, a real-time temperature distribution matrix within the vehicle body is constructed (i.e., replacing the element at the corresponding location in the sensor location distribution matrix with the real-time temperature value (i.e., the identification number of the temperature sensor)).
[0080] The system acquires real-time solar radiation data (i.e., the real-time horizontal radiation of the ground surface at the vehicle's location (total solar radiation entering a unit horizontal surface of the ground) and sunshine duration) at the vehicle's current location. Based on the real-time solar radiation data and the vehicle's three-dimensional shape model (i.e., the model representing the vehicle's three-dimensional shape and size), it generates a solar radiation-induced temperature rise matrix inside the vehicle (i.e., a matrix constructed by taking the temperature rise values caused by solar radiation at the locations of all temperature sensors inside the vehicle according to the locations of the temperature sensors). The solar radiation-induced temperature rise matrix and the real-time temperature distribution matrix are identical matrices.
[0081] The product of the solar temperature determination mitigation weight (i.e., the degree of interference of the temperature rise value in different temperature ranges caused by solar radiation on the final determination temperature used to determine whether to issue a high temperature warning) and the solar radiation influence temperature rise matrix is used as the pseudo temperature rise matrix in the vehicle body (i.e., the matrix constructed according to the setting position of the temperature sensors, where the pseudo temperature rise value is the temperature rise value brought by the current solar radiation to the setting position of all temperature sensors in the vehicle body, and the real-time temperature value detected by the temperature sensors includes this part of the temperature rise value. However, this part of the temperature rise value is caused by the solar radiation rather than by damage to the components in the vehicle body or excessive temperature. Therefore, this part of the temperature rise value is pseudo and needs to be excluded from the real-time temperature value).
[0082] Subtract the real-time temperature distribution matrix and the pseudo temperature rise matrix inside the vehicle body to obtain the vehicle body temperature judgment matrix (that is, a matrix containing the judgment temperature values used to determine whether the temperature at the setting location of all temperature sensors inside the vehicle body is too high).
[0083] If an element in the vehicle body temperature determination matrix is found to be not less than the determination temperature threshold (i.e., the minimum unsafe temperature inside the vehicle body, which is the temperature value inside the vehicle body that reaches the determination temperature threshold due to component damage or other temperature rises besides natural factors such as sunlight, then an overheating warning signal needs to be issued), an overheating warning signal is generated (i.e., a signal used to remind the user on the APP that the component damage inside the vehicle body has caused local or large-area overheating). Based on the overheating warning signal, a warning reminder is issued on the APP monitoring program on the smart mobile terminal (i.e., a reminder message containing the overheating warning signal). The temperature sensor corresponding to the element in the vehicle body temperature determination matrix that is not less than the determination temperature threshold is displayed on the APP monitoring program at its setting location inside the vehicle body. At the same time, the second light panel 2 is controlled to flash as a reminder (to remind on-site personnel outside the vehicle body that there is a local or large-area overheating phenomenon inside the vehicle body).
[0084] The PCB board is connected to a smart mobile terminal via the Internet of Vehicles (IoV).
[0085] This embodiment uses a real-time temperature distribution matrix and a solar radiation-induced temperature rise matrix within the vehicle body, combined with a weighted approach to mitigate solar radiation temperature, to obtain a vehicle body temperature determination matrix. This matrix can be used to determine whether the temperature inside the vehicle body has reached the threshold requiring a hug. This determination method not only considers the real-time temperature at various points within the vehicle body but also eliminates the influence of solar radiation on the real-time temperature. Based on this determination result, a high temperature warning and a flashing control of the second luminous panel 2 are implemented. This avoids excessive warnings caused by false temperature rises due to solar radiation data affecting the temperature sensor, improves the utilization efficiency of the second luminous panel 2, and enhances the intelligent monitoring level of the vehicle's interior temperature.
[0086] Example 10:
[0087] Based on Example 9, real-time solar radiation data of the vehicle's current location is obtained. Based on this real-time solar radiation data and the vehicle's three-dimensional shape model, a solar radiation-induced temperature rise matrix within the vehicle body is generated, including:
[0088] Based on real-time solar radiation data of the vehicle's current location and the vehicle's 3D shape model, the solar radiation temperature rise value at all points on the vehicle's exterior surface is determined (based on real-time solar radiation data, the total solar radiation and sunshine duration within each unit area of the vehicle's exterior surface are determined, and the solar radiation temperature rise value at all points on the vehicle's exterior surface is calculated based on the total solar radiation and sunshine duration within each unit area of the vehicle's exterior surface, for example...). Where ΔT is the solar radiation temperature rise value, δ is the conversion coefficient, which is the conversion coefficient that converts the total solar radiation into the temperature value, T is the current continuous sunshine time, Sr(t) is the total solar radiation that enters the surface of each unit area of the vehicle body at time t, and the solar radiation temperature rise value is the temperature rise value caused by the solar radiation at the location of all temperature sensors in the vehicle body.
[0089] Based on the temperature influence range of each location point on the outer surface of the vehicle (i.e., the area affected by the solar radiation temperature rise at the location point on the inner surface of the vehicle, the temperature influence range is determined based on the solar radiation temperature rise at the location point, generally following the principle that the higher the solar radiation temperature rise, the larger the corresponding temperature influence range), the temperature influence range of each temperature sensor's setting location is determined (i.e., the solar radiation temperature rise at the location point corresponding to the temperature influence range will cause temperature interference (temperature rise) at the setting location of the temperature sensor).
[0090] Based on the local thermal conduction attenuation coefficient (which characterizes the degree of thermal conduction attenuation between two points in the vehicle body, and is specifically related to the vehicle body material, and is determined in advance based on multiple experiments) and conduction distance (which is the distance between the temperature sensor and the corresponding point in the temperature influence range), the solar radiation temperature rise values at the temperature sensor's location are calculated (which is the ratio between the difference between 1 and the local thermal conduction attenuation coefficient and the solar radiation temperature rise value at the corresponding point).
[0091] Based on the sum of all solar radiation temperature rise values at the location of each temperature sensor in the vehicle body, a solar radiation temperature rise matrix is constructed inside the vehicle body (that is, a matrix is constructed by combining the sum of all solar radiation temperature rise values at the location of each temperature sensor in the vehicle body according to the location of the temperature sensors, and the temperature sensor corresponding to each matrix element in the solar radiation temperature rise influence matrix is the same as the temperature sensor corresponding to the matrix element at the same location in the sensor location distribution matrix).
[0092] This embodiment determines the solar radiation temperature rise value at a location on the outer surface of the vehicle body based on solar radiation data and solar radiation projection simulation results obtained from the vehicle's 3D model. It then calculates the solar radiation effect temperature rise value at the temperature sensor location caused by the solar radiation temperature rise data on the outer surface of the vehicle body using a conduction attenuation calculation process. This allows for the accurate construction of solar radiation effect temperature rise data inside the vehicle body.
[0093] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
