Description

Technical Field

[0001] This utility model relates to the field of automotive interior roof technology, and in particular to automotive interior roof structures with integrated lighting systems. Background Technology

[0002] The integrated lighting system's interior roof structure serves as a control component for lighting specific areas within the vehicle's interior roof. By fixing it to the vehicle's roof and installing individual lighting units at designated locations within this interior roof structure, the integrated lighting system can effectively illuminate the vehicle's interior.

[0003] In most common automotive headliner structures for integrated lighting systems, the lighting system frame is fixed to the headliner, and components controlling the integrated lighting circuit are installed and arranged within the headliner. The headliner houses and controls the integrated lighting system. While these common automotive headliner structures for integrated lighting systems offer good installation and control, some problems still exist:

[0004] 1. In the common integrated lighting system of automobiles, the lighting system is turned on and off by a switch, which makes its functionality relatively simple.

[0005] 2. In common integrated lighting systems, the lighting fixtures and related components of the car's interior roof structure are often fixed to this structure, which means that the system can only illuminate specific areas inside the car. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an integrated lighting system for an automotive interior roof structure, comprising an interior roof structure main body, the interior roof structure main body including a charging docking component and a lighting component, the lighting component being installed at the lower part inside the charging docking component, the charging docking component including a mounting base and a charging base, the mounting base being disposed at the top of the charging docking component, the charging base being fixedly connected to the bottom of the mounting base, the lighting component including a docking base, a control component, a lamp frame, a switch button, an integrated lighting module, and a focus adjustment structure, the docking base being disposed at the top of the lighting component, the control component being fixedly connected to the top part inside the docking base, the lamp frame being fixedly connected to the bottom part of the docking base, the switch button being installed inside the outer wall of the lamp frame, the integrated lighting module being installed at the top part inside the lamp frame, and a focus adjustment structure being fixedly connected to the lower part inside the lamp frame, the focus adjustment structure including an adjustment groove, a support plate, a guide rod, an adjustment plate, a guide groove, a hinge rod, an aperture plate, and an adjustment rod, the adjustment groove being formed on the outer wall of the lamp frame.

[0008] When in use, the mounting bracket is soldered to the designated location on the car roof structure. The internal circuit board of the mounting bracket houses a power conversion module, a communication interface, and a protection circuit. The power conversion module is a step-down chip that converts the car's electrical power into the voltage required for battery charging. The communication interface can be a USB-PD controller for device identification and charging protocol negotiation, ensuring stable charging of the lithium battery. The protection circuit uses a reverse current blocking diode and a TVS transient voltage suppressor to prevent reverse voltage surges. The control components include a charging management chip, a battery pack, an LED driver circuit, and its control unit. The charging management chip can be an integrated PMU power management unit and an I2C communication module to control the charging and discharging of the lithium battery. The battery pack can be a lithium polymer battery and its independent protection board to provide power to the integrated lighting module. The LED driver circuit and its control unit can be a constant current driver chip and an MCU microcontroller to electronically adjust the lighting operation of the integrated lighting module. The circuit board inside the mounting bracket is connected to the integrated circuit system in the car's infotainment system via a wiring harness, allowing the mounting bracket to be powered by the car.

[0009] Preferably, the mounting base is equipped with a corresponding circuit board, and the circuit board is soldered with a power conversion module, a communication interface and a protection circuit. The mounting base can stably charge the lighting components through the circuit modules.

[0010] Preferably, the control component is equipped with a charging management chip, a battery pack, an LED driver circuit and its control unit, which can stably charge the lithium battery and provide stable power to the integrated lighting module through various module circuits.

[0011] Preferably, a support plate is fixedly connected to the inner side wall of the lamp frame, a guide rod is fixedly connected to the bottom end of the support plate, an adjustment plate is rotatably connected to the bottom of the support plate, a guide groove is provided inside the adjustment plate, a hinge rod is hinged to the bottom end of the adjustment plate, an aperture plate is hinged to one side of the top end of the hinge rod, and an adjustment rod is fixedly connected to one end of the adjustment plate.

[0012] Preferably, the support plate and the aperture plate have a rotating structure, and the guide grooves are distributed in a ring shape inside the adjustment plate.

[0013] Preferably, the top of the charging base is provided with a separate lighting structure, which includes a limiting groove, a neodymium magnet, an embedded spring pin, a metal ring, a power contact, and a limiting protrusion. The limiting groove is formed in the inner side wall of the charging base. A neodymium magnet is fixedly connected to the top of the charging base. An embedded spring pin is fixedly connected to the inside of the middle part of the top of the lamp frame. A metal ring is fixedly connected to the inside of the top of the docking seat. A power contact passes through the middle part of the top of the docking seat. Limiting protrusions are fixedly connected to both ends of the docking seat.

[0014] Preferably, the limiting grooves are symmetrically distributed on the inner sidewall of the charging base, and the power contacts are linearly connected to the control components.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by using the embedded spring pin and the contact charging and lighting components equipped with the control components, the charging docking component can be separated from the lighting component for illumination, and the expansion and contraction of several aperture plates can be adjusted by the push-pull adjustment rod, thereby adjusting the illumination aperture range of the integrated lighting module.

[0016] 1. By pushing and pulling the adjustment rod, several aperture plates are gradually opened and closed. When the aperture plates gradually close, the lighting range of the integrated lighting module becomes more concentrated and smaller, while as the aperture plates open, the lighting range of the integrated lighting module becomes more dispersed and larger, thereby improving the functionality of the car's interior roof structure.

[0017] 2. The battery pack within the control unit provides power to the integrated lighting module, allowing the driver to use the lighting unit to illuminate a designated location. After use, the lighting unit is reinstalled into the charging socket, causing the embedded spring pin to contact the power contacts and energize the battery pack within the control unit for the next use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5The integrated lighting system for automobile interior roof structure provided by this utility model includes an interior roof structure main body 1. The interior roof structure main body 1 includes a charging docking component 2 and a lighting component 3. The lighting component 3 is installed at the lower part inside the charging docking component 2. The charging docking component 2 includes a mounting base 201 and a charging base 202. The mounting base 201 is located at the top of the charging docking component 2, and the charging base 202 is fixedly connected to the bottom of the mounting base 201. A corresponding circuit board is installed inside the mounting base 201, and a power conversion module, a communication interface, and a protection circuit are soldered onto the circuit board. The lighting component 3 includes a docking base 301, a control component 302, a lamp frame 303, a switch button 304, an integrated lighting module 305, and a focus adjustment structure 4. The docking base 301 is located at the top of the lighting component 3. The control component 302 is fixedly connected to the top of the docking base 301. A charging management chip, a battery pack, an LED driver circuit, and its control unit are soldered onto the control component 302. The lamp frame 303 is fixedly connected to the bottom of the docking base 301. A switch button 304 is installed inside the outer wall of the lamp frame 303. An integrated lighting module 305 is installed at the top inside the lamp frame 303. A focusing adjustment structure 4 is fixedly connected to the lower part inside the lamp frame 303. The focusing adjustment structure 4 includes an adjustment groove 401, a support plate 402, a guide rod 403, an adjustment plate 404, a guide groove 405, a hinge rod 406, an aperture plate 407, and an adjustment rod 408. The adjustment groove 401 is formed on the outer wall of the lamp frame 303. A switch button 304 is fixedly connected to the inner wall of the lamp frame 303. A support plate 402 is provided, and a guide rod 403 is fixedly connected to the bottom end of the support plate 402. An adjustment plate 404 is rotatably connected to the bottom of the support plate 402. A guide groove 405 is provided inside the adjustment plate 404. A hinge rod 406 is hinged to the bottom end of the adjustment plate 404. An aperture plate 407 is hinged to one side of the top end of the hinge rod 406. An adjustment rod 408 is fixedly connected to one end of the adjustment plate 404. The support plate 402 and the aperture plate 407 are in a rotating structure. The guide groove 405 is distributed in a ring inside the adjustment plate 404.

[0026] See attached document Figure 2 , Figure 4 and Figure 5When the car interior roof structure is in use, in order to improve the functionality of the integrated lighting system, several aperture plates 407 are set in the lamp frame 303. By pushing and pulling the adjustment rod 408, the adjustment plate 404 is rotated at a certain angle inside the lamp frame 303. During the rotation, several hinge rods 406 push the corresponding corner of the aperture plate 407. Since the corresponding corner of the aperture plate 407 is in a rotating structure with the support plate 402, as the hinge rods 406 push and pull, the aperture plates 407 are controlled to gradually open and close. When the aperture plates 407 gradually close, the lighting range of the integrated lighting module 305 becomes more concentrated and smaller. As the aperture plates 407 open, the lighting range of the integrated lighting module 305 becomes more dispersed and larger, thereby improving the functionality of the car interior roof structure.

[0027] The top of the charging base 202 is provided with a separate lighting structure 5. The separate lighting structure 5 includes a limiting groove 501, a neodymium magnet 502, an embedded spring pin 503, a metal ring 504, a power contact 505, and a limiting protrusion 506. The limiting groove 501 is opened in the inner side wall of the charging base 202. The neodymium magnet 502 is fixedly connected to the top of the charging base 202. An embedded spring pin 503 is fixedly connected to the middle part of the top of the lamp frame 303. A metal ring 504 is fixedly connected to the top of the docking seat 301. A power contact 505 passes through the middle part of the top of the docking seat 301. Both ends of the docking seat 301 are fixedly connected to the limiting protrusion 506. The limiting groove 501 is symmetrically distributed in the inner side wall of the charging base 202. The power contact 505 is linearly connected to the control component 302.

[0028] See attached document Figure 2 , Figure 3 and Figure 4 Because the power conversion module, communication interface, and protection circuit are soldered onto the internal circuit board of the mounting base 201, and the charging management chip, battery pack, LED driver circuit, and control unit are soldered onto the control component 302, the integrated lighting module 305 can be independently powered and illuminated by the lighting component 3. By rotating the lighting component 3 along the limiting groove 501, the limiting protrusion 506 is disengaged from the limiting groove 501, thereby separating the charging docking component 2 and the lighting component 3. At this time, the battery pack in the control component 302 can provide power to the integrated lighting module 305, allowing the driver to pick up the lighting component 3 to illuminate a designated location. After use, the lighting component 3 is reinstalled into the charging base 202, so that the embedded spring pin 503 contacts the power contact 505 to provide power, and the battery pack in the control component 302 is charged for the next use.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
