Description
Technical Field
[0001] This utility model relates to the field of automotive charging technology, and in particular to an automotive charging port light. Background Technology
[0002] In existing automotive charging systems, the charging port light and the switch that controls its on / off state are typically two independent components. Specifically, the charging port light assembly includes a separate housing, a light-emitting element, and a corresponding circuit module, while the switch is located as a separate control component in other parts of the vehicle body (such as the trim panel near the charging port). The two are electrically connected and transmit signals through one or more wiring harnesses.
[0003] This separate design has significant drawbacks in practical applications: because the wiring harness needs to be laid inside the vehicle body, its length is often determined by the installation location requirements, and some areas of the harness lack a stable fixing structure. During automobile production and assembly, the wiring harness may be pulled due to improper handling; during vehicle operation, vehicle vibrations can cause continuous friction between the wiring harness and surrounding components; during daily use or maintenance, accidental contact may cause the wiring harness to be squeezed or bent. All of these situations can easily lead to damage to the wiring harness insulation layer and breakage of internal wires, resulting in the charging port indicator failing to turn on and off properly. This affects the user's observation and operation of the charging port in dim environments, and may even cause short circuits due to poor circuit contact, significantly reducing the product's reliability.

The indicator light group is mounted on a PCB board, and the light guide strip is arranged around the mounting hole with the light-incident end of the light guide strip close to the light-emitting end of the indicator light group.
[0008] Furthermore, the light guide strip includes a light-transmitting part and two first light-receiving parts, the indicator light group includes two first indicator lights, the light-emitting ends of the two first light-receiving parts are respectively connected to the light-transmitting part, the light-transmitting part surrounds the mounting hole, the two first indicator lights are located between the switch device and the mounting hole, and the light-inlet end of one first light-receiving part corresponds to the light-emitting end of one first indicator light.
[0009] Furthermore, the indicator light group also includes two second indicator lights, and the light guide strip also includes two second light receiving parts. The light-emitting ends of the two second light receiving parts are respectively connected to the light-transmitting part. The two second indicator lights are respectively located at opposite ends of the switching device, and the light-inlet end of one second light receiving part corresponds to the light-emitting end of one second indicator light.
[0010] Furthermore, it also includes a diffusion ring, which is mounted on the outside of the housing and arranged around the mounting hole.
[0011] Furthermore, the shape of the diffusion ring is adapted to the shape of the light guide strip, and the width of the diffusion ring is greater than the width of the light guide strip.
[0012] Furthermore, one side of the housing is recessed inward to form a receiving groove for placing the switch device, the receiving groove being located on one side of the mounting hole.
[0013] Furthermore, the receiving groove and the mounting hole are arranged side by side on the same side of the housing, and the line connecting their centers coincides with the central axis of the housing.
[0014] Furthermore, the receiving groove is a through groove that penetrates the inner cavity of the housing, and the switching device is embedded into the inner cavity of the housing and mounted on the PCB board through the through groove.
[0015] The beneficial effects of this utility model are as follows: By integrating the switching device and the light-emitting device into the same housing, with the light-emitting device positioned opposite the car charging port, and both the switching device and the light-emitting device electrically connected to the PCB board, this structural design eliminates the wiring harness connecting the switching device and the light-emitting device in the traditional separate design.

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0018] Please refer to Figure 1 as well as Figure 2 The technical solution adopted by this utility model is as follows: A car charging port light includes a housing 1 installed in the car charging port. The housing 1 has a PCB board 2 and a light-emitting device 3 inside. The light-emitting device 3 is arranged opposite to the car charging port. The housing 1 also has a switch device 4. Both the switch device 4 and the light-emitting device 3 are electrically connected to the PCB board 2.
[0019] As can be seen from the above description, the beneficial effects of this utility model are as follows: By integrating the switch device 4 and the light-emitting device 3 into the same housing 1, with the light-emitting device 3 positioned opposite the car charging port, and both the switch device 4 and the light-emitting device 3 electrically connected to the PCB board 2, this structural design eliminates the wiring harness connecting the switch device 4 and the light-emitting device 3 in the traditional separate design. This fundamentally avoids the problem of the exposed wiring harness being pulled or bumped during transportation and ensures the stability of signal transmission between the switch device 4 and the light-emitting device 3, thereby improving the reliability and durability of the product.
[0020] For further details, please refer to Figure 1 and Figure 6 The housing 1 has a through mounting hole 11 for the car charging port to pass through, and the switch device 4 is located on one side of the mounting hole 11.
[0021] As can be seen from the above description, the mounting hole 11 provides a passage for the car charging port, ensuring that the charging function can be realized normally; the switch device 4 is located on one side of the mounting hole 11, which will not interfere with the plugging and unplugging of the charging gun, and allows the user to conveniently operate the switch near the charging port, which is in line with usage habits.
[0022] For further details, please refer to Figure 2 The light-emitting device 3 includes a light guide strip 31 and an indicator light group 32. The indicator light group 32 is mounted on the PCB board 2. The light guide strip 31 is arranged around the mounting hole 11 and the light-incident end of the light guide strip 31 is arranged close to the light-emitting end of the indicator light group 32.
[0023] As can be seen from the above description, the design of the light guide strip 31 surrounding the mounting hole 11 can evenly guide the light from the indicator light group 32 to the periphery of the charging port, ensuring that users can clearly observe the location and charging status of the charging port in dim environments; the light-incident end of the light guide strip 31 is close to the indicator light group 32, which reduces the attenuation of light during transmission, improves light utilization, and enhances the lighting and indication effect.
[0024] For further details, please refer to Figure 2 and Figure 3 The light guide strip 31 includes a light-transmitting part 311 and two first light receiving parts 312. The indicator light group 32 includes two first indicator lights 321. The light-emitting ends of the two first light receiving parts 312 are respectively connected to the light-transmitting part 311. The light-transmitting part 311 surrounds the mounting hole 11. The two first indicator lights 321 are located between the switch device 4 and the mounting hole 11. The light-inlet end of one first light receiving part 312 corresponds to the light-emitting end of one first indicator light 321.
[0025] As can be seen from the above description, the two first light receiving units 312 correspond to the two first indicator lights 321 respectively, and can efficiently transmit the light in the area between the switch device 4 and the mounting hole 11 to the light transmitting unit 311, making up for the possible light blind spots in this area, making the light distribution around the charging port more uniform, and improving the overall lighting.
[0026] For further details, please refer to Figure 2 and Figure 3 The indicator light group 32 further includes two second indicator lights 322, and the light guide strip 31 further includes two second light receiving parts 313. The light emitting ends of the two second light receiving parts 313 are respectively connected to the light transmitting part 311. The two second indicator lights 322 are respectively located at opposite ends of the switching device 4. The light receiving end of one second light receiving part 313 corresponds to the light emitting end of one second indicator light 322.
[0027] As can be seen from the above description, the cooperation between the second indicator light 322 and the second light receiving unit 313 can supplement light from the opposite ends of the switching device 4 to the light transmitting part 311, further optimizing the overall brightness uniformity of the light transmitting part 311; at the same time, the different light emission modes (such as color and flashing frequency) of the first indicator light 321 and the second indicator light 322 can also distinguish the charging stage or fault state, enhancing the richness of the function prompts.
[0028] For further details, please refer to Figure 6 It also includes a diffusion ring 5, which is installed outside the housing 1 and surrounds the mounting hole 11.
[0029] As can be seen from the above description, the diffusion ring 5 can scatter the light emitted from the light guide strip 31, changing the light from concentrated direct light to soft diffused light, avoiding the stimulation of the user's eyes by local strong light, and improving the visual comfort during use.
[0030] For further details, please refer to Figure 1 , Figure 2 and Figure 6 The shape of the diffusion ring 5 is adapted to the shape of the light guide strip 31, and the width of the diffusion ring 5 is greater than the width of the light guide strip 31.
[0031] As can be seen from the above description, the shape of the diffusion ring 5 is adapted to the shape of the light guide strip 31, and the width of the diffusion ring 5 is greater than the width of the light guide strip 31. In this way, the diffusion ring 5 can completely cover the light-emitting area of the light guide strip 31, ensuring that the light is diffused without any omissions or dead angles, making the light around the charging port more uniform and soft.
[0032] For further details, please refer to Figure 5 One side of the housing 1 is recessed inward to form a receiving groove 12 for placing the switch device 4, and the receiving groove 12 is located on one side of the mounting hole 11.
[0033] As can be seen from the above description, the receiving groove 12 provides a dedicated installation space for the switch device 4, which can not only provide physical protection for the switch device 4 to prevent damage caused by external collisions, but also ensure the stable installation of the switch device 4 on the housing 1, and avoid loosening or displacement during use.
[0034] For further details, please refer to Figure 5 The receiving groove 12 and the mounting hole 11 are arranged side by side on the same side of the housing 1, and the line connecting their centers coincides with the central axis of the housing 1.
[0035] As can be seen from the above description, the receiving groove 12 and the mounting hole 11 are arranged side by side and the center line is coincident with the axis of the housing 1, so that the overall structure presents a symmetrical layout, which not only improves the appearance but also conforms to the ergonomic design. When the user plugs in or unplugs the charging gun, the hand can naturally touch the switch, making the operation more convenient.
[0036] For further details, please refer to Figure 2 and Figure 5 The receiving groove 12 is a through groove that penetrates the inner cavity of the housing 1. The switching device 4 is embedded in the inner cavity of the housing 1 through the through groove and installed on the PCB board 2.
[0037] As can be seen from the above description, the through-slot design allows the switch device 4 to be directly embedded in the inner cavity of the housing 1 and connected to the PCB board 2, which simplifies the installation process of the switch device 4, while ensuring the stability of the electrical connection between the switch device 4 and the PCB board 2, reducing the risk of functional failure caused by poor contact, and further improving product reliability.

[0047] Please refer to Figure 5 One side of the housing 1 is recessed inward to form a receiving groove 12 for placing the switch device 4, and the receiving groove 12 is located on one side of the mounting hole 11.
[0048] Please refer to Figure 5The receiving groove 12 and the mounting hole 11 are arranged side by side on the same side of the housing 1, and the line connecting their centers coincides with the central axis of the housing 1.
[0049] Please refer to Figure 2 and Figure 5 The receiving groove 12 is a through groove that penetrates the inner cavity of the housing 1. The switching device 4 is embedded in the inner cavity of the housing 1 through the through groove and installed on the PCB board 2.
[0050] The switching device 4 is a push switch, and there is a gap between the groove wall of the receiving groove 12 and the outer wall of the push switch.
[0051] Please refer to Figure 7 and Figure 8 The push switch includes a button assembly and a micro switch 44. The micro switch 44 is mounted on the PCB board 2. The button assembly is located directly above the trigger end of the micro switch 44.

[0057] The working process of the car charging port light in this solution is as follows: When the user needs to use the charging port light, press the switch device 4 on the housing 1 to trigger the switch signal; The switch signal is transmitted to the indicator light group 32 through the circuit on PCB board 2, which controls the indicator light group 32 to light up. The light emitted by the indicator light group 32 enters the first light receiving part 312 and the second light receiving part 313 of the light guide strip 31 respectively, and is transmitted to the light transmitting part 311 through the first light receiving part 312 and the second light receiving part 313. The light-transmitting part 311 of the light guide strip 31 directs the light to the area around the car charging port, and the light is diffused by the diffusion ring 5 to form uniform and soft lighting. When the user presses the switch device 4 again, the switch signal controls the indicator light group 32 to turn off through the PCB board 2, completing one working cycle.
[0058] Throughout the process, the signal transmission between the switching device 4 and the light-emitting device 3 is directly achieved through the PCB board 2, without the need for external wiring harnesses. This completely avoids functional failures caused by wiring harness damage and ensures the stable operation of the charging port light under various working conditions.
