[0002] The automotive lamp mounting structure is a component used to fix and connect the vehicle lamp to the vehicle body. It typically includes components such as lamp housing, bracket, bolts, clips, and gaskets. Its design must ensure that the lamp is installed securely, while also having shockproof, waterproof, and adjustable functions. Common structures include bolt-fastening, clip-fastening, or sliding rail types to adapt to the needs of different vehicle models. During installation, it is necessary to align with the pre-drilled holes on the vehicle body, fix it with screws or clips, and seal the interface to prevent water ingress, ensuring that the light angle meets safety standards. Existing automotive lamp mounting structures often present numerous inconveniences during disassembly and assembly. In particular, snap-on designs are prone to breakage due to uneven force or material aging during disassembly, leading to loosening of the lamp or failure of the seal. Some bolt fastening structures are difficult to disassemble and assemble due to narrow locations and hard-to-access tools, and may even become impossible to disassemble due to rust or stripped threads.

[0003] In conclusion, to improve the ease of maintenance and installation reliability of automotive lamps, it is necessary to address the problems of difficult disassembly and assembly and easy breakage of clips in the existing structure, so that the lamp body can be quickly disassembled, while reducing the risk of component damage due to improper operation, thereby extending the service life of the lamps and ensuring driving safety.

[0013] Preferably, there are three sets of fixing seats, which are distributed circumferentially along the inner wall of the fixing shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model employs a cooperative structure of claws and positioning seats. During disassembly and assembly, simply rotating the positioning seat releases the constraint on the claws in advance, allowing them to slide out smoothly. This significantly reduces disassembly and assembly resistance. This design avoids the risk of breakage caused by forced prying of traditional snap-fit ​​structures, while also reducing wear on the installation parts caused by repeated disassembly. The operation process does not require excessive external force, improving maintenance efficiency, ensuring the long-term reliability of the connection between the lamp body and the vehicle body, effectively extending the lamp's service life, and reducing the risk of seal failure or light misalignment due to improper installation.

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] Refer to the instruction manual appendix Figures 1 to 6 A snap-fit ​​automotive lamp mounting structure that is easy to install and disassemble includes a lamp body 1 and a fixing ring 3. A fixing shell 2 is fixed to the rear side of the lamp body 1. The fixing ring 3 is fixedly connected to the vehicle frame. A positioning mechanism is provided on the fixing ring 3. A docking seat 4 is connected to the positioning mechanism. The positioning mechanism is used to drive the docking seat 4 to rotate and lock the docking seat 4. A connecting mechanism is provided inside the fixing shell 2. A claw 6 is provided on the connecting mechanism. The connecting mechanism is used to drive the claw 6 to rotate and reset. A slot 7 is opened on the outer side of the docking seat 4. The claw 6 is adapted to the slot 7.

[0019] It should be noted that the positioning mechanism provides an installation base for the docking seat 4, which can assist in the rotation and unlocking of the docking seat 4. It provides an operational basis for the smooth disengagement or engagement of the claw 6 and the slot 7, avoiding structural damage caused by direct hard disassembly. When installing the headlight body 1, the fixing shell 2 is aligned with the docking seat 4 and inserted. Then, the docking seat 4 is rotated so that the slot 7 moves to the position of the claw 6. Under the drive of the connecting mechanism, the tip of the claw 6 is inserted into the slot 7 to achieve locking. When disassembly is required, the docking seat 4 is rotated again so that the slot 7 disengages from the claw 6.

[0020] Refer to the instruction manual appendix Figures 2 to 4 The connecting mechanism includes an installation component disposed inside the fixed housing 2 and a reset component disposed on the installation component. The installation component is used to connect the claw 6, and the reset component is used to drive the claw 6 to reset.

[0021] It should be noted that the mounting component provides support and a rotation fulcrum for the claw 6, while the reset component ensures that the claw 6 can automatically return to its initial position after disengaging from the slot 7, facilitating the next installation.

[0022] Refer to the instruction manual appendix Figures 2 to 4The mounting components include a mounting base 51 installed inside the mounting housing 2 and a rotating shaft located inside the mounting base 51. The rotating shaft is rotatably connected to the mounting base 51, and the pawl 6 is fixedly connected to the rotating shaft.

[0023] It should be noted that the fixed base 51 provides a stable mounting foundation, while the rotating shaft enables the rotational connection between the chuck 6 and the fixed base 51.

[0024] Refer to the instruction manual appendix Figures 2 to 4 The reset assembly includes a torsion spring 52 sleeved on the outside of the rotating shaft. One end of the torsion spring 52 is fixedly connected to the fixed base 51, and the other end of the torsion spring 52 is fixedly connected to the pawl 6.

[0025] It should be noted that the torsion spring 52 utilizes its elastic deformation characteristics to drive the claw 6 to rotate when the slot 7 moves to the position of the claw 6, so that it can be engaged in the slot 7.

[0026] Refer to the instruction manual appendix Figures 2 to 6 The positioning mechanism includes a connecting component, a locking component, and a fixing component disposed on the fixed ring 3. The connecting component is used to position the docking seat 4, the locking component is used to lock the docking seat 4, and the fixing component is used to connect the fixed ring 3 to the frame.

[0027] It should be noted that the connecting component ensures that the docking seat 4 is accurately positioned and can rotate, the locking component ensures that the docking seat 4 is stable in the working state, and the fixing component reliably installs the entire positioning mechanism onto the frame.

[0028] Refer to the instruction manual appendix Figures 2 to 6 The connecting assembly includes a positioning ring 81 fixed on a fixing ring 3 and a bearing disposed inside the positioning ring 81. The mating seat 4 is fixedly connected to the bearing and is rotatably connected to the positioning ring 81 through the bearing.

[0029] It should be noted that the positioning ring 81 provides the installation reference, while the bearing greatly reduces the frictional resistance when the mating seat 4 rotates, making the operation smoother.

[0030] Refer to the instruction manual appendix Figures 2 to 6 The locking assembly includes a fixing ring 82 fixed to the outside of the docking seat 4, a ratchet 83 disposed on the outside of the fixing ring 82, a positioning ring 84 fixed on the fixing ring 3, and a ratchet groove 85 formed on the inside of the positioning ring 84, wherein the ratchet 83 and the ratchet groove 85 are adapted to each other.

[0031] It should be noted that the locking assembly securely locks the mating seat 4 after it has rotated into place through the meshing action of the ratchet 83 and the ratchet groove 85, preventing it from rotating accidentally.

[0032] Refer to the instruction manual appendix Figures 2 to 6The fixing component includes multiple positioning holes formed on the fixing ring 3 and fixing bolts 86 connected inside the positioning holes. The fixing ring 3 is fixedly connected to the frame by the fixing bolts 86.

[0033] It should be noted that the fixing components, through the cooperation of multiple positioning holes and fixing bolts 86, ensure a firm and reliable connection between the fixing ring 3 and the frame.

[0034] Refer to the instruction manual appendix Figure 3 and Figure 4 There are three sets of fixing seats 51, which are distributed in a circular pattern along the inner wall of the fixing shell 2.

[0035] It should be noted that the design of the three sets of fixed seats 51 evenly distributed along the circumference provides symmetrical and stable support for the docking seat 4, ensuring balanced and stable force on the connection.

[0036] Working principle: When installing the headlight body 1, first align the fixing shell 2 and put it on the outside of the docking seat 4. Then rotate the docking seat 4 so that the slot 7 on the outside of the docking seat 4 moves to the position of the claw 6 inside the fixing shell 2. At this time, under the elastic force of the torsion spring 52 on the outside of the rotating shaft, the tip of the claw 6 automatically rotates and gets into the slot 7 of the docking seat 4 to lock it. At the same time, the ratchet 83 on the fixing ring 82 on the outside of the docking seat 4 engages with the ratchet groove 85 on the inner side of the positioning ring 84 on the fixing ring 3 to lock the docking seat 4 and prevent it from rotating. When disassembling, continue to rotate the docking seat 4 to drive the slot 7 to disengage from the tip of the claw 6. At this time, the fixing shell 2 and the headlight body 1 can be removed from the docking seat 4, realizing the function of quick disassembly and assembly.
