[0002] Interior lighting refers to the lighting system installed inside a vehicle to meet the visual needs of occupants in various environments. Light bulbs, LED beads, and other components in interior lighting are consumable parts that may be damaged after a period of use. Therefore, there is a particular need for an interior lighting component that is easy to disassemble.

[0003] However, if traditional car interior dome lights use a complex mounting method, replacing the bulb may require disassembling the entire headliner. Due to the complexity of the disassembly process, repair personnel need to have high skills and experience to avoid damaging the headliner or other parts during the operation. This means that repair shops may need to arrange experienced technicians to perform this work, thereby increasing labor costs. In addition, if the headliner or other parts are damaged due to improper operation, additional costs will be required to replace these parts. Utility Model Content

[0004] The purpose of this utility model is to provide an easily detachable vehicle interior lighting component, which enables quick installation and removal of the interior lighting lamp cover, thus solving the problem of increased costs caused by the complex fixing method of traditional vehicle interior dome lights.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an easily detachable vehicle interior lighting component, including a mounting base, a lamp holder connected above the mounting base, a lighting lamp installed inside the lamp holder, a lamp cover installed on the surface of the lamp holder, a base mounting component provided on the surface of the mounting base, and lamp cover mounting components provided on the surfaces of the lamp holder and the lamp cover.

[0006] The lampshade mounting assembly includes a threaded block, which is fixedly connected to the upper outer surface of the lamp holder. A threaded groove is provided on the inner side of the lampshade. A telescopic hole is provided inside the threaded block. A second spring is connected to the inner end of the telescopic hole. A limit plate is connected to the other end of the second spring. A locking block is connected to the outer end of the limit plate. A locking hole is provided on the inner side of the threaded groove.

[0007] Preferably, the base mounting assembly includes a threaded hole, which is formed on the surface of the mounting base and the object to be connected. A screw is threadedly connected inside the threaded hole, and a connecting block is connected to the top of the screw. A telescopic rod is connected to the center of the connecting block. Limiting blocks are connected to both sides of the top of the telescopic rod. A telescopic tube is slidably connected to the outside of the telescopic rod. A limiting groove is formed on the inside of the telescopic tube. A first spring is wound around the outside of the telescopic rod and the telescopic tube. A cross-shaped retaining plate is connected to the top of the telescopic tube. A stop groove is formed on the surface of the mounting base.

[0008] Preferably, multiple sets of screws are provided on the surface of the mounting base, and the multiple sets of screws are symmetrically distributed in a cross shape with respect to the center of the mounting base.

[0009] Preferably, the telescopic tube slides up and down on the outside of the telescopic rod via a limiting groove and a limiting block, and the outer wall size of the limiting block matches the inner wall size of the limiting groove.

[0010] Preferably, one end of the first spring is fixedly connected to the inner side of the connecting block, and the other end is fixedly connected to the bottom side of the cross plate. The position of the cross plate corresponds to the position of the stop groove, and the size of the bottom of the cross plate is adapted to the size of the stop groove.

[0011] Preferably, the lampshade is mounted on the surface of the lamp holder via a threaded block and a threaded groove, and the threaded block and the threaded groove are precisely sized together.

[0012] Preferably, the limiting plate and the locking block cooperate to form a telescopic structure, and the outer wall size of the locking block matches the inner wall size of the locking hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This easy-to-disassemble vehicle interior lighting component, through the setting of the base mounting component, multiple sets of screws can make the mounting base and the roof more evenly distributed, effectively dispersing the external force generated by bumps and vibrations during vehicle driving, avoiding excessive force on a single connection point leading to loosening or damage, and the cross-shaped retaining plate and the stop groove form a reliable elastic locking structure to prevent the screws from loosening and falling off due to vehicle bumps and vibrations.

[0015] 2. This easily detachable in-vehicle lighting component, through the design of the lamp cover mounting assembly, achieves a tight connection between the lamp cover and the lamp holder through the precise fit of the threaded block and threaded groove. The precisely fitted threaded structure can effectively prevent dust, moisture, etc. from entering the lamp holder, providing a good sealing effect. At the same time, after the lamp cover is installed in place, the locking block can accurately engage with the locking hole, providing additional limiting and fixing functions for the lamp cover, preventing it from loosening or rotating due to vibration during vehicle operation. In addition, the telescopic structure allows the locking block to extend and retract flexibly during installation and disassembly, ensuring both the convenience of installation and enhancing the stability of the lamp cover connection, further improving the practicality and reliability of the in-vehicle lighting component.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: an easily detachable vehicle interior lighting component, including a mounting base 1, a lamp holder 2 connected above the mounting base 1, a lighting lamp 3 installed inside the lamp holder 2, a lamp cover 4 installed on the surface of the lamp holder 2, a base mounting component 5 provided on the surface of the mounting base 1, and a lamp cover mounting component 6 provided on the surfaces of the lamp holder 2 and the lamp cover 4.

[0025] The lampshade mounting assembly 6 includes a threaded block 601, which is fixedly connected to the upper outer surface of the lamp holder 2. A threaded groove 602 is formed on the inner side of the lampshade 4. An expansion hole 603 is formed inside the threaded block 601. A second spring 604 is connected to the inner end of the expansion hole 603. A limit plate 605 is connected to the other end of the second spring 604. A locking block 606 is connected to the outer end of the limit plate 605. A locking hole 607 is formed on the inner side of the threaded groove 602. The lampshade 4 is mounted using the lampshade mounting assembly 6. When the inner threaded groove 602 of the lampshade 4 is aligned with the threaded block 601 on the lamp holder 2, the lampshade 4 is rotated clockwise. As the threaded block 601 gradually screws into the threaded groove 602, the engagement of the threads generates an axial thrust, causing the lampshade 4 to move closer to the lamp holder 2. When the threaded block 601 is about to be fully screwed into the threaded groove 602, the locking block 606 begins to contact the inner side of the threaded groove 602. Since the outer side of the locking block 606 is a sloping surface, under the action of the slope force, the locking block 606 will compress the second spring 604 and move towards the telescopic hole 6. 03. When the locking block 606 rotates to align with the locking hole 607, the second spring 604, freed from the external pressure of the locking block 606, rapidly extends under its own elasticity, pushing the limiting plate 605 and the locking block 606 outward. This allows the locking block 606 to precisely engage with the locking hole 607, completing the secure connection between the lamp cover 4 and the lamp holder 2. At this point, the combined effect of the threaded structure and the locking structure not only ensures that the lamp cover 4 will not loosen due to vibrations during vehicle operation but also effectively prevents the lamp cover 4 from accidentally falling off and disassembling. At time 4, simply rotate the lamp cover 4 counterclockwise. The locking block 606 is subjected to the reverse force generated by the rotation of the thread, which compresses the second spring 604 again and retracts it into the telescopic hole 603. After the locking block 606 disengages from the locking hole 607, continue to rotate the lamp cover 4. The threaded block 601 gradually unscrews out of the threaded groove 602, and the lamp cover 4 can be easily removed. This makes it convenient to inspect, clean or replace the internal lighting lamp 3. The entire disassembly process does not require any additional tools. The operation is simple and quick, which effectively improves the convenience of maintaining the vehicle's interior lighting components.

[0026] Furthermore, the base mounting assembly 5 includes a threaded hole 501, which is formed on the surfaces of the mounting base 1 and the object to be connected. A screw 502 is threadedly connected inside the threaded hole 501. A connecting block 503 is connected to the top of the screw 502. A telescopic rod 504 is connected to the center of the connecting block 503. Limiting blocks 505 are connected to both sides of the top of the telescopic rod 504. A telescopic tube 506 is slidably connected to the outside of the telescopic rod 504. A limiting groove 507 is formed on the inner side of the telescopic tube 506. A first spring 508 is wound around the outside of the telescopic rod 504 and the telescopic tube 506. A cross is connected to the top of the telescopic tube 506. The mounting base 1 has a stop groove 510 on its surface. During installation, the mounting base 1 is first placed against the surface of the vehicle roof, aligning the threaded holes 501 on both surfaces. The screw 502 is then screwed into the threaded hole 501. As the screw 502 continues to screw in, the connecting block 503 gradually approaches the mounting base 1, causing the telescopic rod 504 and the limiting block 505 to move upwards. When the cross-shaped mounting plate 509 approaches the surface of the mounting base 1, the telescopic tube 506 is blocked by the mounting base 1, causing the telescopic rod 504 to slide within the telescopic tube 506, compressing the first spring 508 wound on the outside. Continue tightening screw 502 until the limiting block 505 slides to align with the limiting groove 507. At this point, the first spring 508 extends under elastic action, pushing the telescopic tube 506 upward, causing the cross-shaped locking plate 509 to engage in the stop groove 510 on the surface of the mounting base 1. This completes the double fixation between the mounting base 1 and the connected object, ensuring a tight connection through the threads and enhancing vibration resistance through the locking structure. During disassembly, rotate screw 502 in the opposite direction, and screw 502 gradually unscrews from the threaded hole 501. The connecting block 503 drives the telescopic rod 504 downward. During the downward movement, the limiting block 505 slides within the limiting groove 507. When the cross plate 509 is about to disengage from the stop groove 510, the first spring 508 is stretched, and the resulting elastic force keeps the telescopic tube 506 and the cross plate 509 in place. Continue to unscrew the screw 502 until the cross plate 509 is completely disengaged from the stop groove 510. At this time, the first spring 508 returns to its original state, and the telescopic rod 504 and the telescopic tube 506 return to their initial state. The mounting base 1 can then be easily removed from the roof of the vehicle. This design simplifies the disassembly steps while ensuring connection strength. Even ordinary users can quickly complete the installation and disassembly of the lighting component base. It is suitable for various scenarios such as vehicle repair and modification.

[0027] Furthermore, multiple sets of screws 502 are provided on the surface of the mounting base 1, and these multiple sets of screws 502 are symmetrically distributed in a "+" shape around the center of the mounting base 1. By setting the screws 502, the force between the mounting base 1 and the connected object can be more evenly distributed, effectively dispersing the external force generated by bumps and vibrations during vehicle operation, and avoiding loosening or damage caused by excessive force on a single connection point. At the same time, the "+" symmetrical distribution design not only enhances the connection stability, but also ensures that the mounting base 1 is subjected to balanced force in all directions. Even if it is subjected to external force impacts from different directions, it can maintain a stable state and improve the overall reliability of the vehicle interior lighting components.

[0028] Furthermore, the telescopic tube 506 slides up and down on the outside of the telescopic rod 504 via the limiting groove 507 and the limiting block 505. The outer wall size of the limiting block 505 matches the inner wall size of the limiting groove 507. Through the setting of the limiting block 505 and the limiting groove 507, the sliding of the telescopic tube 506 is precisely guided and limited. On the one hand, it prevents the telescopic tube 506 from shifting or rotating during the sliding process, ensuring that the cross plate 509 can be accurately engaged in the stop groove 510. On the other hand, the tight size fit can effectively reduce the sway gap between the telescopic tube 506 and the telescopic rod 504, further enhancing the stability after the mounting base 1 is connected, and also reducing the noise caused by component shaking.

[0029] Furthermore, one end of the first spring 508 is fixedly connected to the inner side of the connecting block 503, and the other end is fixedly connected to the bottom side of the cross plate 509. The position of the cross plate 509 corresponds to the position of the stop groove 510, and the size of the bottom of the cross plate 509 is adapted to the size of the stop groove 510. Through the arrangement of the first spring 508, the cross plate 509, and the stop groove 510, a reliable elastic locking structure is formed. The first spring 508 provides a stable elastic force for the cross plate 509, enabling it to be firmly locked into the stop groove 510, thereby enhancing the connection strength between the mounting base 1 and the connected object. At the same time, during disassembly, the elastic deformation of the first spring 508 can also assist the cross plate 509 to smoothly disengage from the stop groove 510, simplifying the disassembly process and making the user operation easier and more convenient.

[0030] Furthermore, the lampshade 4 is mounted on the surface of the lamp holder 2 via a threaded block 601 and a threaded groove 602. The threaded block 601 and the threaded groove 602 are precisely matched in size. Through the setting of the threaded block 601 and the threaded groove 602, not only is a tight connection between the lampshade 4 and the lamp holder 2 achieved, but it can also automatically center during rotation, ensuring the accuracy of the lampshade's installation position. The precisely matched threaded structure can effectively prevent dust, moisture, etc. from entering the lamp holder, playing a good sealing role, protecting the lighting lamp 3 from the influence of the external environment, and extending its service life. In addition, the threaded connection method allows users to quickly disassemble and install the lampshade as needed, facilitating the maintenance and replacement of the internal lighting components.

[0031] Furthermore, the limiting plate 605, through the cooperation of the second spring 604 and the locking block 606, forms a telescopic structure. The outer wall size of the locking block 606 matches the inner wall size of the locking hole 607. With the setting of the locking block 606 and the locking hole 607, after the lamp cover 4 is installed in place, the locking block 606 can accurately lock into the locking hole 607, providing additional limiting and fixing functions for the lamp cover 4, preventing it from loosening or rotating due to vibration during vehicle operation. At the same time, the telescopic structure allows the locking block 606 to extend and retract flexibly during installation and disassembly, which not only ensures the convenience of installation but also enhances the stability of the lamp cover 4 connection, further improving the practicality and reliability of the in-vehicle lighting components.

[0032] Working principle: When installing the interior lighting components, firstly, the mounting base 1 is fixed to the connected object such as the roof using the mounting base assembly 5. Align the threaded holes 501 on the surface of the mounting base 1 and the connected object, and screw in the screw 502. As the screw 502 is screwed in, it drives the connecting block 503, the telescopic rod 504, and the limiting block 505 to move upward. The telescopic tube 506 slides relative to the telescopic rod 504 under the obstruction of the mounting base 1, compressing the first spring 508 until the limiting block 505 aligns with the limiting groove 507. The first spring 508 extends and pushes the cross-shaped locking plate 509 into the stop groove 510, achieving double fixation of the mounting base 1 and ensuring its stable installation on the roof. Then, the lamp cover 4 is installed. Install component 6, align the threaded groove 602 on the inner side of the lamp cover 4 with the threaded block 601 on the lamp holder 2, and rotate the lamp cover 4 clockwise. As the threaded block 601 screws into the threaded groove 602, the axial thrust generated by the thread engagement brings the lamp cover 4 closer to the lamp holder 2. When the locking block 606 contacts the inner side of the threaded groove 602, its inclined slope is compressed by the force, causing the second spring 604 to retract until the locking block 606 aligns with the locking hole 607. The second spring 604 then extends, pushing the locking block 606 into the locking hole 607, completing the stable connection between the lamp cover 4 and the lamp holder 2, forming a double fixing structure of thread and locking. During vehicle operation, multiple sets of symmetrically distributed "+" shaped screws 502 ensure that the mounting base 1 is evenly stressed, dispersing the force generated by bumps and vibrations. The external force, the precise engagement of the limiting block 505 and the limiting groove 507, prevents the telescopic tube 506 from shifting, reduces component wobbling gaps and noise. The first spring 508 provides stable elasticity to the cross plate 509, maintaining its engagement with the stop groove 510, ensuring the connection strength of the mounting base 1. The threaded block 601 and the threaded groove 602 fit tightly, enabling the lamp cover 4 to automatically center and preventing dust and moisture from entering the lamp holder. The engagement of the locking block 606 and the locking hole 607 provides additional limiting for the lamp cover 4, preventing it from loosening or rotating due to vibration, ensuring that the lighting lamp 3 works normally in a stable environment, providing illumination for the vehicle interior. When it is necessary to inspect or replace the lighting lamp 3 or clean the lamp cover 4, the disassembly process is equally convenient. For the lamp cover 4, the reverse clockwise... Rotating the needle compresses the second spring 604, causing it to retract and disengage from the locking hole 607. Continuing to rotate the screw 601 allows for easy removal of the lamp cover 4. When disassembling the mounting base 1, rotating the screw 502 in the opposite direction causes the connecting block 503 and telescopic rod 504 to move downwards. The limiting block 505 slides within the limiting groove 507, and the first spring 508 stretches the auxiliary cross-shaped locking plate 509, disengaging it from the stop groove 510. After unscrewing the screw 502, the telescopic rod 504 and telescopic tube 506 return to their initial state, allowing the mounting base 1 to be removed from the roof. The entire disassembly process requires no complex tools, facilitating quick maintenance of the lighting components. This completes the process of using an easily disassembled in-vehicle lighting component.
