Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a D-pillar exterior trim panel with a hidden charging indicator light. Background Technology

[0002] The D-pillar trim panel is a decorative and functional covering located on the exterior of the D-pillar area at the rear of the vehicle. It is typically used on SUVs, MPVs, or station wagons, which have a prominent D-pillar structure. As a crucial structural support connecting the roof and rear sidewalls, the D-pillar trim panel not only enhances the vehicle's appearance and streamlined look but also improves aerodynamic performance. D-pillar trim panels are often made of engineering plastics, ABS materials, or chrome-plated trim, offering excellent weather resistance, UV protection, and impact resistance, enabling them to withstand various complex climates. Furthermore, some high-end models integrate a third brake light (high-mounted brake light) or incorporate a hidden rear wiper outlet on the D-pillar trim panel, further enhancing safety and overall aesthetics. With the continuous evolution of automotive design, the D-pillar trim panel is increasingly used to create visual effects such as floating roofs and privacy glass, becoming an indispensable part of modern automotive styling language.

[0003] The electric vehicle market is gradually expanding. In electric vehicles, the design of the D-pillar exterior panel not only continues the aesthetic and functional requirements of traditional gasoline vehicles but also incorporates design concepts and technological integration unique to electric vehicles. With the increasing popularity of electric vehicles, charging has become a core aspect of users' daily lives.

[0004] Some existing D-pillar exterior trim panels lack charging status indicator lights, requiring drivers to return to the driver's seat to check the charging status via the central control screen or mobile app after plugging in the charger. This is inconvenient, as it prevents drivers from immediately checking whether the charger is charging or other charging status information upon plugging in. Furthermore, there is no indication when the charger is not properly plugged in and the driver has not checked the charging status via the central control screen or mobile app, posing a safety hazard and causing unnecessary inconvenience to users.

[0005] Secondly, some existing D-pillar exterior trim panels have charging indicator lights, but under sunlight or ambient light, the indicator light elements can be seen through the trim panel, affecting the vehicle's aesthetics. When the indicator light is on, uneven light display can cause light leakage and halos, which greatly affects the vehicle's appearance and the user experience, thus impacting the vehicle's quality. Utility Model Content

[0006] This application provides a D-pillar exterior trim panel with a concealed charging indicator light, employing the following technical solution: A concealed charging indicator light on a D-pillar exterior trim panel includes: a trim panel body, an indicator light device, a mounting groove formed on the back of the trim panel body; a semi-transparent panel disposed on the front of the trim panel body; the indicator light device includes a lamp housing and a light-emitting group, the light-emitting group being disposed within the lamp housing, the indicator light device being installed in the mounting groove, and the indicator light device corresponding to the semi-transparent panel; and a power connector disposed on the indicator light device.

[0007] Preferably, the light transmittance of the semi-transparent panel is 10% to 15%.

[0008] Preferably, the lamp housing is divided into a base and a light diffuser, the light diffuser is fixedly connected to the base, the light-emitting lamp group is disposed between the base and the light diffuser, and the light diffuser faces the semi-transparent panel.

[0009] Preferably, a foam pressing area is provided around the light-diffusing mask, and foam is provided between the light-diffusing mask and the semi-transparent panel. The foam and the foam pressing area cooperate to achieve that the thickness of the foam after cooperating with the foam pressing area is consistent with the thickness of the center of the light-diffusing mask.

[0010] Preferably, the base has a groove, and the power connector is placed in the groove.

[0011] Preferably, the light-emitting lamp assembly is provided with screws, and the light-emitting lamp assembly is fixedly connected to the lamp housing by the screws.

[0012] Preferably, the light-emitting lamp assembly is divided into a first lamp panel and a second lamp panel, and a connector is provided between the first lamp panel and the second lamp panel, and the first lamp panel and the second lamp panel are connected by the connector.

[0013] Preferably, the decorative panel body is provided with a breathable membrane, which is located on the front side of the decorative panel body.

[0014] Preferably, a foam frame is provided on the back of the decorative panel body to prevent light leakage from the light-emitting lamp assembly.

[0015] Preferably, a number of mounting clips are fixedly connected to the back of the decorative panel body.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The D-pillar exterior trim panel, through a semi-transparent panel and indicator light device, ensures that the internal indicator light device is invisible under normal sunlight and external lighting conditions, maintaining the overall clean and aesthetically pleasing appearance of the D-pillar exterior trim panel. When the vehicle is charging, the indicator light device illuminates, and the light from the indicator light device is evenly distributed on the semi-transparent panel through a light diffuser, avoiding light leakage or halo problems caused by excessive light transmission. This achieves non-intrusive charging status reminders, which not only do not compromise the aesthetics but also effectively convey charging information, significantly improving the user experience and enhancing charging safety.

[0017] 2. This D-pillar exterior trim panel uses a light source consisting of a first light panel and a second light panel, which are connected by a connector to achieve a flexible layout. This allows it to be adapted to different D-pillar curvatures or length requirements and facilitates future maintenance. If a single light panel is damaged, only that light panel needs to be replaced, resulting in lower maintenance costs. Furthermore, the foam at the junction of the diffuser and the semi-transparent panel effectively prevents dust, seals, and cushions the light. This ensures that the thickness of the foam bonding area is consistent with the height of the center of the diffuser, preventing local protrusions that could cause panel deformation or changes in the lighting angle, thus improving the overall durability of the device.

[0032] An embodiment of this utility model provides a D-pillar exterior trim panel with a concealed charging indicator light.

[0033] Example 1: As Figure 1-9The image shows a concealed charging indicator light on a D-pillar exterior trim panel, comprising: a trim panel body 1, an indicator light device 2, a mounting groove 101 formed on the back of the trim panel body 1; a semi-transparent panel 102 disposed on the front of the trim panel body 1; the indicator light device 2 comprising a lamp housing 3 and a light-emitting group 4, the light-emitting group 4 disposed within the lamp housing 3, the indicator light device 2 mounted within the mounting groove 101, and the indicator light device 2 corresponding to the semi-transparent panel 102; and a power connector 403 disposed on the indicator light device 2. The semi-transparent panel 102 has a light transmittance of 10%. With a light transmittance of 10%, the indicator light device 2 can be effectively protected from excessively strong external light, especially under direct sunlight, extending its service life. Furthermore, the indicator light device 2 can be normally transmitted through the semi-transparent panel 102 during charging. The lamp housing 3 is divided into a base 301 and a light diffuser 302. The light diffuser 302 is fixedly connected to the base 301. The light-emitting lamp group 4 is disposed between the base 301 and the light diffuser 302, with the light diffuser 302 facing the semi-transparent panel 102. A foam pressing area 321 is provided around the periphery of the light diffuser 302. Foam 5 is provided between the light diffuser 302 and the semi-transparent panel 102. The foam 5 cooperates with the foam pressing area 321 to achieve a thickness consistent with the central thickness of the light diffuser 302. A groove 311 is provided on the base 301, and the power connector 403 is placed within the groove 311. Screws 7 are provided on the light-emitting lamp group 4, which are fixedly connected to the lamp housing 3 via the screws 7. The light-emitting light assembly 4 is divided into a first light panel 401 and a second light panel 402. A connector 404 is provided between the first light panel 401 and the second light panel 402, and the first light panel 401 and the second light panel 402 are connected by the connector 404. A breathable membrane 6 is provided on the trim panel body 1. The breathable membrane 6 is located on the front of the trim panel body 1. The breathable membrane 6 is used to prevent moisture from being generated inside the trim panel body 1 due to environmental conditions such as temperature difference and humidity, which could damage the electronic components inside the indicator light device 2. Moisture residue on the inner wall of the semi-transparent panel 102 would also reduce the light transmission effect of the indicator light device 2 due to moisture. A foam frame 8 is provided on the back of the trim panel body 1 to prevent light leakage of the light-emitting light assembly 4. Several mounting clips 9 are fixedly connected to the back of the trim panel body 1, and the whole assembly is installed with the vehicle mounting part through the foam frame 8 and the mounting clips 9.

[0034] In this embodiment, the wall thickness of the semi-transparent panel 102 is optionally 3.5 mm, and the overall thickness of the decorative panel body 1 is optionally 3 mm. In the area where the mounting buckle 9 is provided, the local thickness of the decorative panel body 1 can be increased to 3.5 mm to enhance structural strength and assembly stability. It should be understood that the above thickness parameters can be adaptively adjusted according to the actual structural design, material properties, and assembly requirements, and this utility model is not limited to specific values.

[0035] The light-emitting group 4 can use low-power LED light sources, such as RGB LEDs with a rated power of approximately 0.2 W, and the number can be set to about 30, arranged evenly in groups of three connected in series. Driven by a control circuit, it can emit various colors such as green, yellow, red, and blue to simulate different states during the charging process, such as charging complete, charging waiting, charging failure, and external discharge. When the vehicle is in a parked charging state, the system can trigger the corresponding color light display based on the current charging information, providing an intuitive visual status indication. It should be understood that the above-mentioned light group parameters can be adaptively adjusted according to the actual structural design, material properties, and actual needs; this utility model is not limited to a specific device.

[0036] The light distribution cover 302 and the base 301 can be fixedly connected by ultrasonic welding or other methods to achieve a good sealing effect and meet environmental reliability requirements such as dustproof and waterproof. Other connection methods that can achieve reliable sealing and fixation (such as laser welding, bonding, or snap-fit) are also within the scope of this utility model.
