Description

Technical Field

[0001] This utility model relates to a charging indicator device for a front through position light, belonging to the field of vehicle parts technology, and particularly to the control and switching of a front center position light and a charging indicator light, and related to vehicles. Background Technology

[0002] The front continuous position light has transformed from a functional component to a design art piece in the automotive styling field. With the trend of electric vehicles eliminating the air intake grille, its horizontal light strip design not only becomes a new visual focus on the front face but also effectively stretches the visual width by 15-20%, creating a more sporty "wide-body, low-slung" styling. As a core carrier of brand DNA, the front continuous position light significantly enhances brand recognition through its unique lighting modes and dynamic interactive functions. In terms of technological innovation, it uses high-transmittance materials such as PMMA / PC combined with microstructure optical design to achieve a uniform light emission effect with a brightness difference of ≤5%; at the same time, it relies on high-precision mold processing and complex curved surface integrated molding technology to ensure product quality. This solution, which integrates aesthetic design and technological innovation, not only creates an 8-12% product premium but also represents the highest level of technology in the automotive lighting field, driving automotive styling design into a new stage of development. Traditional charging indicator lights are installed at the charging port, a space that is usually too small to accommodate a small charging indicator light with a diameter of about 20mm. This size only ensures normal function, but the status of the indicator light is not easy to observe. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a charging indicator device for a front through position light. The charging indicator light is integrated into the position light, which makes it easy to see the charging status of the car intuitively. It solves the space problem of the installation position of the charging indicator light. The front through position light is about 1m long, which provides enough space for the charging indicator light to be distributed horizontally. At the same time, the charging indicator light also borrows the shape of the position light, so there is no need to drill holes or reserve positions, which reduces the manufacturing cost of the car.

[0004] Prior to this invention, a charging indicator device for a front through-type position light is provided, characterized in that it includes a battery monitoring and management system, a front through-type position light microcontroller, a charging indicator light, a front through-type position light, a low-dropout linear regulator, and several constant current chips. The charging indicator light includes several LEDs and is fixedly installed inside the front through-type position light, which is installed at the front of the vehicle. The battery monitoring and management system is electrically connected to the front through-type position light microcontroller, which is electrically connected to the low-dropout linear regulator and several constant current chips. The several constant current chips are electrically connected to the several LEDs, which are divided into several groups, with each group of LEDs representing a charging level.

[0005] Prior to this, the LED lights are divided into 10 groups, representing 10 charging levels.

[0006] Prioritized, it includes 68 LED lights, which are divided into 10 groups, representing 10 charging levels.

[0007] Preferredly, the 68 LEDs are horizontally distributed, with each group consisting of two LEDs. Groups 1-5 illuminated LEDs represent the car's charging progress as follows: groups 6-8 represent 10%-20%; groups 9-11 represent 20%-30%; groups 12-14 represent 30%-40%; and groups 15-17 represent 40%... The charging progress indicator shows the charging progress from -50%. LEDs 18 to 20 illuminate when the car is at 50% to 60% charging progress; LEDs 21 to 23 illuminate when the car is at 60% to 70% charging progress; LEDs 24 to 26 illuminate when the car is at 70% to 80% charging progress; LEDs 27 to 29 illuminate when the car is at 80% to 90% charging progress; and LEDs 30 to 34 illuminate when the car is at 90% to 100% charging progress.

[0008] The beneficial effects achieved by this utility model are:

[0009] This invention primarily solves the problems of inconvenient visibility and high cost associated with integrating the charging indicator light into the front through-type position light, allowing the charging indicator light and position light to share the same shape, light source, and light-emitting surface. The charging indicator light in this invention employs high-precision LED control technology, achieving intuitive status feedback through dynamic light effects. This evolution not only enhances the user experience but also promotes the overall improvement of the intelligence level of new energy vehicles.

[0010] This invention integrates the front through-type position light and the charging indicator light, which can significantly reduce development costs by about 30% and achieve an integrated design of "one light for multiple uses". At the same time, it improves the overall styling design. This integrated design not only reduces costs and increases efficiency, but also promotes the development of automotive lighting systems towards intelligence and multi-functionality, providing an innovative approach to cost control for new energy vehicles.

[0020] See Figure 1This application provides a charging indicator device for a front through-type position light, including a battery monitoring and management system, a front through-type position light microcontroller, a charging indicator light, a front through-type position light, a low-dropout linear regulator, and several constant current chips. The charging indicator light includes several LEDs and is fixedly installed inside the front through-type position light, which is installed at the front of the vehicle. The battery monitoring and management system is electrically connected to the front through-type position light microcontroller, which is electrically connected to the low-dropout linear regulator and several constant current chips. The several constant current chips are electrically connected to the several LEDs, which are divided into several groups, with each group of LEDs representing a charging level.

[0021] Furthermore, the LED lights are divided into 10 groups, representing 10 charging levels.

[0022] Furthermore, it includes 68 LED lights, which are divided into 10 groups, representing 10 charging levels.

[0023] Furthermore, the 68 LEDs are horizontally distributed, with each group consisting of two LEDs. Groups 1-5 illuminated indicate the car is charging at 0%-10%; groups 6-8 indicate 10%-20%; groups 9-11 indicate 20%-30%; groups 12-14 indicate 30%-40%; and groups 15-17 indicate 40%... The charging progress indicator shows the charging progress from -50% to 60%. LEDs in groups 18-20 illuminate when the car is at 50% to 60% charging progress. LEDs in groups 21-23 illuminate when the car is at 60% to 70% charging progress. LEDs in groups 24-26 illuminate when the car is at 70% to 80% charging progress. LEDs in groups 27-29 illuminate when the car is at 80% to 90% charging progress. LEDs in groups 30-34 illuminate when the car is at 90% to 100% charging progress.

[0024] The charging indicator light is integrated into the front through-type position light. The charging indicator light and the front through-type position light share the same shape, light source and light-emitting surface. The charging indicator light uses a total of 68 0.2W LEDs, and each LED has a luminous flux of 5.5lm.

[0025] Table 1

[0026] LED quantity power Luminous flux 68 0.2W 5.5LM

[0027] As shown in Table 2, the 68 LEDs are divided into 34 groups of 2. The 34 groups of LEDs are divided into 10 charging levels, with level 1 and level 10 corresponding to 5 groups of LEDs and the remaining levels corresponding to 3 groups of LEDs. The LEDs light up in sequence according to the charging progress.

[0028] Table 2

[0029]

[0030] As shown in Table 3, the charging status is divided into three states: not charging / standby, charging, and fault. In the not charging / standby state, the charging indicator light is off.

[0031] During charging, the Battery Monitoring and Management System (BMS) outputs the electrical status to the Microcontroller Unit (MCU) of the front through-beam position lights in real time via CAN signal. After the MCU parses the CAN signal, it controls each group of LED lights via CAN signal. The LED lights light up sequentially according to Table 2. When fully charged, all 34 groups of LED lights light up. In the event of a charging fault, the BMS outputs a fault signal to the MCU controlling the front through-beam position lights via CAN signal. After receiving the fault signal, the front through-beam position lights control the 34 groups of LED lights to flash rapidly.

[0032] Table 3

[0033]

[0034]

[0035] like Figure 2 Regarding the control logic for charging indication: The BMS outputs the power status to the MCU in real time via the CAN bus. After the MCU parses the CAN signal, it controls each group of LEDs through the CAN physical layer. The LEDs light up sequentially according to Table 2. When fully charged, all 34 groups of LEDs light up.

[0036] like Figure 3 The BMS transmits the charging status in real time via the CAN bus. Since each position light circuit board has a CAN receiver, the MCU and the CAN receiver can transmit CAN signals through the CAN physical layer. The MCU controls each group of LEDs through the CAN signals. The 64 LEDs are divided into groups of 2. After the MCU parses the charging status, it starts to control the turn-on sequence of each group of LEDs.

[0037] Figures 4 to 6 This is a 3D diagram of the electrical architecture and installation structure of the front through position light (i.e., charging indicator light), such as... Figure 4The battery monitoring and management system 1, the front compartment wiring harness 2, and the front through position light 3 are related structural components of the electrical architecture of the front through position light (charging indicator light); such as Figure 5 The left front combination light 4, right front combination light 5, left front headlight 6, right front headlight 7, and front bumper 8 are structural components associated with the installation of the front through position lights.

[0038] like Figure 6 The front through position light is installed last compared to the front bumper and other lights, making installation and maintenance convenient as it does not require disassembling other lights on the front bumper during maintenance. The front through position light has dimensions of 214mm in width, 953mm in length, and 112mm in height.

[0039] like Figure 5 First, install the left front combination light 4, right front combination light 5, left front headlight 6, and right front headlight 7. Then, install the front bumper 8 and the front through position light 3. The installation and removal of the front through position light 3 do not involve the left front combination light 4, right front combination light 5, left front headlight 6, right front headlight 7, and front bumper 8. The front compartment wiring harness 2 connects the battery monitoring and management system 1 and the front through position light 3, and transmits CAN signals through the front compartment wiring harness 2.

[0040] like Figure 4 The battery monitoring and management system 1 outputs real-time charging status to the front through-type position lights 3 via the CAN bus. The front through-type position lights 3 contain 68 LEDs arranged in groups of two, totaling 34 groups. These 34 groups are divided into 10 charging levels, with levels 1 and 10 corresponding to 5 groups of LEDs each, and the remaining levels corresponding to 3 groups of LEDs each. The LEDs are grouped and illuminated sequentially according to the charging progress. (See the charging status diagram below.) Figure 1 Regarding the control logic for charging indication: The BMS outputs the power status to the MCU in real time via CAN signal. After the MCU parses the CAN signal, it controls each group of LEDs via CAN signal. The LEDs light up sequentially according to Table 2. When fully charged, all 34 groups of LEDs light up.
