Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and specifically to a highly sealed automotive waterproof headlight. Background Art

[0002] A headlight is an essential part of a vehicle. It is a tool for road lighting when the vehicle is driving in a dark environment, and at the same time, it is also a tool for sending various vehicle driving signals between vehicles. From the perspective of existing technologies, after a general headlight has been used for a long time, the water vapor inside the headlight is not easily dissipated. In a special environment, water vapor or even water is likely to enter the inside of the lamp cover, causing damage to the headlight and the vehicle, presenting a certain degree of danger. Moreover, there are numerous vehicle models, and most of them produce headlights separately, resulting in troublesome later replacements and incompatibility with multiple vehicle models.

[0003] The temperature difference between the inside and outside of the headlight is likely to form condensed water inside the sealing cover. Long-term accumulation leads to short circuits in the circuit, corrosion of the reflective coating, or atomization of the lamp cover (such as the common "fogging" problem of halogen / LED lights). Traditional headlights rely on fixed sealing rings or adhesive sealing, and are prone to aging and cracking after long-term thermal expansion and contraction or vibration. When an integrated headlight is damaged, it needs to be replaced as a whole. For some modular designs, the front bumper still needs to be disassembled. At the same time, during emergency braking / collision, the inertial displacement of the lamp head may break the wire. Summary of the Invention

[0014] Preferably, the outer ring surface of the piston piece one fits on the inner wall of the embedded sealing cylinder, and the outer ring surface of the piston piece two fits on the inner wall of the sealed lamp cover.

[0015] The present invention provides an automotive waterproof headlight with high sealing performance, having the following beneficial effects: 1. The present invention has the effects of intelligent self-sealing and automatic moisture discharge: Through the cooperation of the linkage sealing mechanism (compression ring, docking ring, sealing rubber ring) and the embedded sealing ring of the external ring frame, multiple sealing layers are automatically formed during installation to ensure the overall airtightness of the lamp installation area. The inertial force of the vehicle's braking start-stop triggers the action of the inertial discharge mechanism, and the piston piece and the counterweight piece are used to push the humid air out through the discharge hole, and then automatically reset and reseal, avoiding internal fogging or water accumulation in the traditional headlight due to long-term use, significantly extending the service life of the lamp. The humid air enters the sealed area of the external lamp sleeve through the output hole of the conical structure of the sealed lamp cover, and is discharged through the discharge hole only under the action of inertia (braking / start-stop) to briefly discharge moisture, without additional energy or sensors, solving the internal condensation problem of the headlight at low cost, especially suitable for high humidity or large temperature difference environments.

[0016] 2. The present invention has a modular quick disassembly and assembly design: The external threaded sleeve cooperates with the extended threaded ring sleeve of the side ring frame II. When rotating, it synchronously pushes the linkage sealing mechanism to be compressed, and at the same time fixes the lamp to the vehicle body. Rotating in the reverse direction can disassemble all components (side ring frame, external ring frame, etc.), simplifying the maintenance process. When a single component is damaged, it can be quickly replaced, reducing the maintenance cost. The embedded power connection post is slidably connected to the power connection sleeve, allowing the lamp head to maintain uninterrupted power supply when displaced due to inertia, avoiding damage caused by wire pulling, and improving electrical reliability.

[0017] 3. The present invention has the ability of inertial-driven active maintenance: Adopting a double-piston air thrust system, the counterweight piece, piston piece I and piston piece I are linked under the action of inertia, respectively pushing the moisture in the sealed lamp cover and the external ring frame into the external lamp sleeve and discharging them centrally. The reset snap ring ensures that the mechanism automatically returns to its position, realizing "zero energy consumption" moisture discharge by using the inertia of the vehicle's daily start-stop, without relying on external power. The liquid storage tank of the built-in positioning cylinder presses the lubricant into the sponge ring through inertia to lubricate the sliding surface of the linkage sliding sleeve, reducing mechanical wear and ensuring the sensitivity of the inertial discharge mechanism during long-term use.

[0018] 4. The present invention has structural integration and improved reliability: Structures such as the internal tooth rubber ring, small-diameter snap ring, and fitting ring form hierarchical sealing, which not only allows relative displacement of components but also ensures complete sealing in the static state, with a high waterproof and dustproof level, suitable for harsh road conditions (such as wading through water, sand and dust). The combined installation method of the threaded grooves of the external ring frame and the side ring frame enhances the overall rigidity, and the counterweight piece balances the inertial force, reducing the impact of vehicle driving vibration on the internal structure of the lamp body.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0022] Please refer to the appendix Figure 1 - Appendix Figure 3 In an embodiment of the present invention, a highly sealed automotive waterproof lamp is provided, including: an external ring frame 1 for fixing the structure of the automotive waterproof lamp; a side ring frame 1 located on the external ring frame 1 for assembling the structure of the automotive waterproof lamp; a side ring frame 2 located on the external ring frame 1 for assembling the structure of the automotive waterproof lamp.

The fitting ring structure of the external ring frame 1 is arranged on the side of the external ring frame 1 close to the lamp head fixing mechanism 4. The side ring frame 1 and the side ring frame 2 are oppositely arranged on both sides of the external ring frame 1 through the thread grooves on both sides of the external ring frame 1. The sealing ring structure of the side ring frame 1 is arranged on the side of the side ring frame 1 away from the external ring frame 1.

At the same time, the inertial force formed when the vehicle brakes and starts can be utilized to discharge the humid air formed by the low temperature inside the lamp body. The overall lamp is assembled and installed through the external ring frame 1.

The linkage sealing mechanism 6 mainly responsible for sealing is sleeved on the external ring frame 1 and the side ring frame 2. When the lamp is installed on the vehicle, it will drive the linkage sealing mechanism 6 to squeeze and seal itself, so that the lamp head fixing mechanism 4, the side ring frame 1, the external ring frame 1, the side ring frame 2, and the lamp tail fixing mechanism 5 form a sealed lamp installation area. The inertial discharge mechanism 7 that forms an air thrust through inertia is sleeved within this lamp installation area.

[0023] Please refer to the appendix Figure 1 - Appendix Figure 12, the lamp holder fixing mechanism 4 is located on the side-mounted ring frame 1, and cooperates with the fitting ring structure of the external ring frame 1, the sealing ring structure of the side-mounted ring frame 1 and the embedded pipe groove structure to seal and fix the lamp head end structure of the lamp. The lamp holder fixing mechanism 4 includes a sealing lamp cover 41 and an external lamp sleeve 42. A conical cylinder structure is provided on the side of the sealing lamp cover 41 away from the light scattering, and it is embedded and slides on the inner wall of the side-mounted ring frame 1. The external lamp sleeve 42 is a conical ring structure and is sleeved and fixed on the outer surface of the conical cylinder structure of the sealing lamp cover 41. At the same time, an output hole structure distributed in a circle is provided between the external lamp sleeve 42 and the conical surface of the conical cylinder structure. A discharge hole structure distributed in a circle is provided on the outer surface of the external lamp sleeve 42. The fitting ring structure of the external ring frame 1 fits on the outer surface of the external lamp sleeve 42 and can cover the discharge hole structure of the external lamp sleeve 42. A side of the external lamp sleeve 42 away from the sealing lamp cover 41 is fixedly connected with an internal tooth rubber ring 43. The internal tooth rubber ring 43 is sleeved and slides on the outside of the side-mounted ring frame 1 and is embedded into the internal part of the external ring frame 1. A small-diameter snap spring structure distributed in a circle is provided between the internal tooth rubber ring 43 and the side wall of the external ring frame 1. A lamp holder 44 is fixedly connected inside the conical cylinder structure of the external lamp sleeve 42. A lighting lamp head 45 is fixed on a side of the lamp holder 44 extending into the sealing lamp cover 41. An embedded power connection post 46 is arranged at the input end of the lighting lamp head 45 and extends into the internal parts of the external ring frame 1 and the side-mounted ring frame 2. Please refer to the appendix Figure 1 - appendix Figure 12, the lamp head fixing mechanism 4 is located on the side-mounted ring frame 1, and cooperates with the fitting ring structure of the external ring frame 1, the sealing ring structure of the side-mounted ring frame 1 and the embedded pipe groove structure to seal and fix the lamp head end structure of the lamp. The lamp head fixing mechanism 4 includes a sealing lamp cover 41 and an external lamp sleeve 42. A conical cylinder structure is provided on the side of the sealing lamp cover 41 away from the light scattering, and it is embedded and slid on the inner wall of the side-mounted ring frame 1. The external lamp sleeve 42 is a conical ring structure and is sleeved and fixed on the outer surface of the conical cylinder structure of the sealing lamp cover 41. At the same time, an output hole structure distributed in a circle is provided between the external lamp sleeve 42 and the conical surface of the conical cylinder structure. A discharge hole structure distributed in a circle is provided on the outer surface of the external lamp sleeve 42. The fitting ring structure of the external ring frame 1 fits on the outer surface of the external lamp sleeve 42 and can cover the discharge hole structure of the external lamp sleeve 42. A side away from the sealing lamp cover 41 of the external lamp sleeve 42 is fixedly connected with an internal tooth rubber ring 43. The internal tooth rubber ring 43 is sleeved and slid on the outside of the side-mounted ring frame 1 and is embedded into the internal part of the external ring frame 1. A small-diameter snap spring structure distributed in a circle is provided between the internal tooth rubber ring 43 and the side wall of the external ring frame 1. A lamp holder 44 is fixedly connected inside the conical cylinder structure of the external lamp sleeve 42. A lighting lamp head 45 is fixed on one side of the lamp holder 44 extending into the sealing lamp cover 41. An embedded power connection post 46 is arranged at the input end of the lighting lamp head 45 and extends into the internal parts of the external ring frame 1 and the side-mounted ring frame 2 3,While the sealing lamp cover 41 included in the lamp holder fixing mechanism 4 is made of a material that can transmit light, it can also be used to install the lighting lamp holder 45 of the vehicle headlamp. A part of the sealing lamp cover 41 is attached to the inner wall of the side-mounted ring frame 1, and an external lamp sleeve 42 for guiding humid air is arranged on the outer surface of its self-added conical cylinder structure. The external lamp sleeve 42 is attached to the fitting ring structure of the external ring frame 1. At the same time, the inner-toothed rubber ring 43 added to the side wall is attached to the surface of the side-mounted ring frame 1. By using the inner tooth surface of the inner-toothed rubber ring 43 and its close contact with the inner wall of the external ring frame 1, a sealed area is formed between the external lamp sleeve 42 and the outer wall of the side-mounted ring frame 1. At the same time, the small-diameter snap ring structure added to the inner wall of the inner-toothed rubber ring 43 and the external ring frame 1 can drive the sealing lamp cover 41 and the external lamp sleeve 42 to reset after inertial displacement. The humid air formed inside the sealing lamp cover 41 due to low temperature can enter the sealed area formed between the external lamp sleeve 42 and the side-mounted ring frame 1 through the output hole structure opened on the conical structure of the sealing lamp cover 41. The discharge hole structures distributed circumferentially on the outer wall of the external lamp sleeve 42 can discharge the humid air in the sealed area of the external lamp sleeve 42. When the sealing lamp cover 41 and the external lamp sleeve 42 are stationary, the discharge hole structure of the external lamp sleeve 42 will be blocked by the fitting ring structure of the external ring frame 1. When the external lamp sleeve 42 and the external lamp sleeve 42 displace due to inertia, the discharge hole structure of the external lamp sleeve 42 displaces simultaneously and breaks away from the blockage of the fitting ring structure, so that the area between the external lamp sleeve 42 and the side-mounted ring frame 1 stops being sealed. The humid air is discharged along the discharge hole structure by the air thrust generated by inertia through the inertial discharge mechanism 7. Until the inertia is eliminated, the small-diameter snap ring structure of the inner-toothed rubber ring 43 drives the sealing lamp cover 41 and the external lamp sleeve 42 to retreat and reset, and the discharge hole structure of the external lamp sleeve 42 follows the reset and is blocked again by the fitting ring structure. Until the vehicle brakes and starts again to form a new inertia, the seal is released again and the humid air is discharged. The lamp socket 44 included in the lamp holder fixing mechanism 4 is installed in the sealing lamp cover 41 and extends into the external ring frame 1 at the same time. The lighting lamp holder 45 is installed and fixed in the sealing lamp cover 41 through the lamp socket 44. The embedded power connection post 46 responsible for powering the lighting lamp holder 45 extends into the external ring frame 1 through the lamp socket 44.,

[0024] Please refer to the appendix Figure 1 - appendix Figure 12, the lamp tail fixing mechanism 5 is located on the side-mounted ring frame two 3. It cooperates with the external thread groove structure of the side-mounted ring frame two 3 and the embedded power connection post 46 to seal and fix the lamp tail end structure of the lamp. The lamp tail fixing mechanism 5 includes an embedded sealing cylinder 51 and an external thread sleeve 52. The embedded sealing cylinder 51 is embedded inside the side-mounted ring frame two 3, and a fitting ring structure is provided on one extended side. The external thread sleeve 52 is sleeved and rotatable on the side of the embedded sealing cylinder 51 away from the fitting ring structure and extends to the side of the side-mounted ring frame two 3 away from the external ring frame 1. An extended thread ring sleeve structure is provided on the side of the external thread sleeve 52 facing the side-mounted ring frame two 3. The extended thread ring sleeve structure of the external thread sleeve 52 is thread-sleeved on the external thread groove of the side-mounted ring frame two 3. The internal positioning cylinder 53 is fixedly connected inside the embedded sealing cylinder 51. The liquid storage tank 54 is fixedly connected to the inner wall of the embedded sealing cylinder 51 on the side away from the external ring frame 1. The output port of the liquid storage tank 54 fits on the outer surface of the internal positioning cylinder 53 and is embedded with an annular sponge structure. The power connection sleeve 55 is fixedly embedded inside the internal positioning cylinder 53. The power connection sleeve 55 is provided with access holes distributed in a circumference. The embedded power connection post 46 is embedded and slid into the access holes of the power connection sleeve 55. The side wall of the power connection sleeve 55 extending outside the embedded sealing cylinder 51 is provided with a power connection end 56,The embedded sealing cylinder 51 included in the lamp tail fixing mechanism 5 is embedded and fitted into the interior of the side-mounted ring frame two 3. A fitting ring structure that can be fitted and sealed with the side-mounted ring frame two 3 is installed on one side extending into the interior of the side-mounted ring frame two 3, and an external threaded sleeve 52 that can be fixedly installed with the vehicle is installed on the other side. The external threaded sleeve 52 itself is restricted to rotate on the embedded sealing cylinder 51. By rotating the external threaded sleeve 52, the lamp can be fixed on the vehicle. An extended threaded ring sleeve structure that can be fixedly installed simultaneously is installed on the side wall of the external threaded sleeve 52 facing the side-mounted ring frame two 3. When the external threaded sleeve 52 is rotated and fixed on the vehicle, the extended threaded ring sleeve structure will rotate accordingly and be rotationally fixed along the external thread groove of the side-mounted ring frame two 3. As the external threaded sleeve 52 continues to rotate, it will push the linkage sealing mechanism 6 sleeved on the surface of the side-mounted ring frame two 3 to operate. Also, by rotating the external threaded sleeve 52 to disengage from the side-mounted ring frame two 3, the embedded sealing cylinder 51 can be disassembled, and then the linkage sealing mechanism 6, the side-mounted ring frame two 3, the external ring frame 1, and the side-mounted ring frame one 2 can be disassembled in sequence, enabling the component structure of the vehicle lamp to be disassembled and quickly replaced. The built-in positioning cylinder 53 installed on the embedded sealing cylinder 51 can restrict the displacement of the inertial discharge mechanism 7 inside the embedded sealing cylinder 51 and the sealing lamp cover 41. The power connection sleeve 55 inside the embedded sealing cylinder 51 is embedded and docked with the embedded power connection post 46, but not fixed. When the sealing lamp cover 41, the external lamp sleeve 42, and the lamp head 45 are displaced due to inertia, the embedded power connection post 46 will displace along the inside of the power connection sleeve 55, but will not disengage from the power connection sleeve 55, and at the same time, the power supply will not be interrupted. A lubricant is pre-stored in the liquid storage tank 54 installed at the end of the built-in positioning cylinder 53. The output port of the liquid storage tank 54 is fitted on the surface of the built-in positioning cylinder 53 and at the same time, a ring-shaped sponge structure is embedded. When the inertia generated by the start and stop of the vehicle's braking drives the lubricant in the liquid storage tank 54 to flow towards the output port of the liquid storage tank 54 and pass through the ring-shaped sponge structure and extend to the surface of the built-in positioning cylinder 53, the inertial discharge mechanism 7 sleeved on the built-in positioning cylinder 53 can slide stably. The power connection end 56 installed at the input port of the power connection sleeve 55 can be docked with the port of the vehicle when the vehicle lamp is installed.,

[0025] Please refer to the appendix Figure 1 - Appendix Figure 10The linkage sealing mechanism 6 is located on the lamp holder fixing mechanism 4, and cooperates with the external threaded sleeve 52 to compress and seal the overall vehicle lamp structure. The linkage sealing mechanism 6 includes a clamping ring 61, a docking ring 62 and an embedded sealing ring 64. The clamping ring 61 is sleeved and slid on the outer ring surface of the side ring frame 23, and the docking ring 62 is sleeved and slid on the side of the outer ring surface of the side ring frame 23 away from the external ring frame 1. A sealing rubber ring 63 is embedded between the clamping ring 61 and the docking ring 62. The embedded sealing ring 64 is embedded and slid to the outer ring surface of the external ring frame 1. A clamping rubber ring 65 is embedded between the clamping ring 61 and the embedded sealing ring 64. A circumferentially distributed large-diameter retaining spring structure is embedded between the side of the embedded sealing ring 64 away from the clamping ring 61 and the outer ring wall of the external ring frame 1. The linkage sealing mechanism 6 sleeved on the surface of the side ring frame 23 includes a clamping ring 61 and a docking ring 62. The two The two are successively installed on the outer ring surface of the side ring frame 23, and the sealing rubber ring 63 installed between the clamping ring 61 and the docking ring 62 can drive the clamping ring 61 and the docking ring 62 to seal each other. The embedded sealing ring 64 included in the linkage sealing mechanism 6 is installed inside the external ring frame 1, and a compression rubber ring 65 for resisting sealing is installed between the embedded sealing ring 64 and the clamping ring 61. When the external threaded sleeve 52 rotates along the surface of the side ring frame 23, the extended threaded sleeve structure configured therein will push the docking ring 62 to move along the outer surface of the side ring frame 23 and be compacted on the surface of the clamping ring 61, and the large-diameter retaining spring structure installed between the embedded sealing ring 64 and the external ring frame 1 can drive the embedded sealing ring 64 to be compacted in the clamping ring 61, so that the linkage sealing mechanism 6 automatically and synchronously forms a sufficient sealing structure on the surfaces of the side ring frame 23 and the external ring frame 1.

[0026] Please refer to the attached Figure 1 -Attached Figure 13The inertia discharge mechanism 7 is located on the lamp holder fixing mechanism 4, and cooperates with the sealed lampshade 41, the embedded sealing cylinder 51, the built-in positioning cylinder 53, the liquid storage tank 54 and the inertia generated when the vehicle starts and stops to continuously discharge the humid gas in the lamp. The inertia discharge mechanism 7 includes a linkage sliding sleeve 71, and the linkage sliding sleeve 71 is sleeved and slid on the surface of the built-in positioning cylinder 53. The side of the linkage sliding sleeve 71 away from the external threaded sleeve 52 is fixedly connected with an arc-shaped slide 72, and the arc-shaped slide 72 penetrates the side wall of the sealed lampshade 41 and extends into the sealed lampshade 41. The side of the linkage sliding sleeve 71 close to the external threaded sleeve 52 is fixedly connected with a piston plate 73, and the intersection of the arc-shaped slide 72 and the linkage sliding sleeve 71 is fixedly connected with a counterweight plate 74, the arc-shaped slide 72 extends to one side of the inside of the sealed lampshade 41 and is fixedly connected with a piston piece 2 75, the outer ring surface of the piston piece 1 73 is attached to the inner wall of the embedded sealing cylinder 51, the outer ring surface of the piston piece 2 75 is attached to the inner wall of the sealed lampshade 41, and a reset spring structure is connected between the piston piece 2 75 and the embedded sealing cylinder 51, and the inertial discharge mechanism 7 embedded in the external ring frame 1, the side ring frame 1 2 and the side ring frame 2 3 is correspondingly installed on the built-in positioning cylinder 53, the linkage sleeve 71 included in the inertial discharge mechanism 7 is sleeved on the surface of the built-in positioning cylinder 53, and the arc-shaped slide 72 included in the inertial discharge mechanism 7 is fixed on the linkage sleeve 71 and moves along the side wall of the sealed lampshade 41 The piston piece 73 is inserted into the sealed lampshade 41, and a piston piece 1 73 is installed on the side of the linkage sleeve 71 close to the external threaded sleeve 52, and a piston piece 2 75 is installed on the side of the arc-shaped slide 72 extending to the inside of the sealed lampshade 41. The counterweight plate 74 installed between the linkage sleeve 71 and the arc-shaped slide 72 will increase the influence of inertia on the inertia discharge mechanism 7. When the piston piece 1 73 is displaced by the forward inertia, it will drive the linkage sleeve 71 and the arc-shaped slide 72 to move, and the counterweight plate 74 and the piston piece 2 75 will move inside the sealed lampshade 41 and the embedded sealing tube 51 respectively, and form air thrust. The piston piece 2 75 will discharge the humid air inside the sealed lampshade 41 along the output hole of the conical tube structure of the sealed lampshade 41 The structure is discharged into the external lamp cover 42, and the counterweight plate 74 squeezes the humid air inside the external ring frame 1 and the embedded sealing tube 51 into the external lamp cover 42 along the embedded pipe groove structure installed on the side ring frame 1. After the sealed lamp cover 41 and the external lamp cover 42 are displaced due to inertia, the discharge hole structure of the external lamp cover 42 is driven to separate from the fitting ring structure of the external ring frame 1 to form a clear state, thereby allowing the humid air to be discharged. When the inertia is eliminated, the piston plate 2 75 retreats and resets due to the reset spring structure installed between the piston plate 2 and the embedded sealing tube 51, and the discharge hole structure of the external lamp cover 42 is also closed after the sealed lamp cover 41 and the external lamp cover 42 retreat and reset, until the vehicle brakes and starts to generate inertia again.

[0027] Working principle: First, the car lamp is mainly installed inside the lamp housing of the vehicle to provide lighting for the vehicle. During its installation process, it can achieve self-sealing. At the same time, it can utilize the inertia formed when the vehicle brakes and starts to discharge the humid air formed by the low temperature inside the lamp body. The overall car lamp is assembled and installed through the external ring frame 1. The threaded groove structures installed on the inner walls of both sides of the external ring frame 1 can drive the side ring frame one 2 and the side ring frame two 3 fixed at the head and tail ends of the lamp to be installed on both sides of the external ring frame 1. The lamp head fixing mechanism 4 composed of the lamp head end structure is installed on the side ring frame one 2, and the lamp tail fixing mechanism 5 composed of the lamp tail end structure is installed on the side ring frame two 3. The linkage sealing mechanism 6 mainly responsible for sealing is sleeved on the external ring frame 1 and the side ring frame two 3. When the car lamp is installed on the vehicle, it will drive the linkage sealing mechanism 6 to squeeze and seal itself, so that the lamp head fixing mechanism 4, the side ring frame one 2, the external ring frame 1, the side ring frame two 3 and the lamp tail fixing mechanism 5 form a sealed lamp installation area. The inertia discharge mechanism 7 that forms air thrust through inertia is sleeved within this lamp installation area. First, the sealing lamp cover 41 included in the lamp head fixing mechanism 4 can be made of a material that can transmit light and is also used to install the car lamp's lighting lamp head 45. A part of the sealing lamp cover 41 fits on the inner wall of the side ring frame one 2, and an external lamp sleeve 42 for guiding humid air is configured on the outer surface of its self-installed conical cylinder structure. The external lamp sleeve 42 fits within the fitting ring structure of the external ring frame 1. At the same time, the internally toothed rubber ring 43 installed on the side wall fits on the surface of the side ring frame one 2. By using the inner tooth surface of the internally toothed rubber ring 43 and its close contact with the inner wall of the external ring frame 1, a sealed area is formed between the external lamp sleeve 42 and the outer wall of the side ring frame one 2. At the same time, the internally toothed rubber ring 43 and the small-diameter snap ring structure installed on the inner wall of the external ring frame 1 can drive the sealing lamp cover 41 and the external lamp sleeve 42 to reset after inertial displacement. The humid air formed inside the sealing lamp cover 41 due to low temperature can enter the sealed area formed between the external lamp sleeve 42 and the side ring frame one 2 along the output hole structure opened on the conical structure of the sealing lamp cover 41. The discharge hole structures circumferentially distributed on the outer wall of the external lamp sleeve 42 can discharge the humid air within the sealed area of the external lamp sleeve 42. When the sealing lamp cover 41 and the external lamp sleeve 42 are stationary, the discharge hole structure of the external lamp sleeve 42 will be blocked by the fitting ring structure of the external ring frame 1. When the external lamp sleeve 42 and the external lamp sleeve 42 displace due to inertia, the discharge hole structure of the external lamp sleeve 42 follows the displacement and simultaneously breaks away from the blockage of the fitting ring structure, causing the area between the external lamp sleeve 42 and the side ring frame one 2 to stop being sealed. The air thrust generated by inertia through the inertia discharge mechanism 7 discharges the humid air along the discharge hole structure until after the inertia is eliminated, the small-diameter snap ring structure of the internally toothed rubber ring 43 drives the sealing lamp cover 41 and the external lamp sleeve 42 to retreat and reset, and the discharge hole structure of the external lamp sleeve 42 follows the reset and is blocked again by the fitting ring structure until the vehicle brakes and starts again to form a new inertia, and the seal is released again to discharge the humid air.The lamp socket 44 included in the lamp head fixing mechanism 4 is installed in the sealed lamp cover 41 and extends into the external ring frame 1 at the same time. The lighting lamp head 45 is installed and fixed in the sealed lamp cover 41 through the lamp socket 44. The embedded power connection post 46 responsible for powering the lighting lamp head 45 extends into the external ring frame 1 through the lamp socket 44. The embedded sealed cylinder 51 included in the lamp tail fixing mechanism 5 is embedded and fitted into the inside of the side ring frame two 3. A fitting ring structure that can be fitted and sealed with the side ring frame two 3 is installed on one side extending into the inside of the side ring frame two 3, and an external thread sleeve 52 that can be fixedly installed with the vehicle is installed on the other side. The external thread sleeve 52 is restricted to rotate on the embedded sealed cylinder 51. By rotating the external thread sleeve 52, the lamp can be fixed on the vehicle. An extended thread ring sleeve structure that can be fixed simultaneously is installed on the side wall of the external thread sleeve 52 facing the side ring frame two 3. When the external thread sleeve 52 is rotated and fixed on the vehicle, the extended thread ring sleeve structure will rotate accordingly and rotate and fix along the external thread groove of the side ring frame two 3. As the external thread sleeve 52 continues to rotate, it will push the linkage sealing mechanism 6 sleeved on the surface of the side ring frame two 3 to operate. By rotating the external thread sleeve 52 to disengage from the side ring frame two 3, the embedded sealed cylinder 51 can be disassembled, and then the linkage sealing mechanism 6, the side ring frame two 3, the external ring frame 1, and the side ring frame one 2 can be disassembled in sequence, so that the component structure of the vehicle lamp can be disassembled and quickly replaced. The built-in positioning cylinder 53 installed on the embedded sealed cylinder 51 can limit the displacement of the inertia discharge mechanism 7 inside the embedded sealed cylinder 51 and the sealed lamp cover 41. The power connection sleeve 55 inside the embedded sealed cylinder 51 is embedded and docked with the embedded power connection post 46, but not fixed. When the sealed lamp cover 41, the external lamp sleeve 42, and the lighting lamp head 45 are displaced due to inertia, the embedded power connection post 46 will displace along the inside of the power connection sleeve 55, but will not disengage from the power connection sleeve 55 and will not interrupt the power supply. A lubricant is pre-stored in the liquid storage tank 54 installed at the end of the built-in positioning cylinder 53. The output port of the liquid storage tank 54 is fitted on the surface of the built-in positioning cylinder 53 and a ring-shaped sponge structure is embedded at the same time. When the vehicle brakes and starts and stops, the inertia will drive the lubricant in the liquid storage tank 54 to flow towards the output port of the liquid storage tank 54 and extend to the surface of the built-in positioning cylinder 53 through the ring-shaped sponge structure, so that the inertia discharge mechanism 7 sleeved on the built-in positioning cylinder 53 can slide stably. The power connection end 56 installed at the input port of the power connection sleeve 55 can be docked with the port of the vehicle when the lamp is installed. The linkage sealing mechanism 6 sleeved on the surface of the side ring frame two 3 includes a pressing ring 61 and a docking ring 62, which are installed on the outer ring surface of the side ring frame two 3 in sequence. A sealing rubber ring 63 installed between the pressing ring 61 and the docking ring 62 can drive the pressing ring 61 and the docking ring 62 to be sealed with each other. The embedded sealing ring 64 included in the linkage sealing mechanism 6 is installed inside the external ring frame 1, and a pressing rubber ring 65 for resisting and sealing is installed between the embedded sealing ring 64 and the pressing ring 61.When the external threaded sleeve 52 rotates along the surface of the side ring frame 23, the extended threaded sleeve structure configured therein will push the docking ring 62 to move along the outer surface of the side ring frame 23 and be pressed on the surface of the clamping ring 61, and the large-diameter retaining spring structure installed between the embedded sealing ring 64 and the external ring frame 1 can drive the embedded sealing ring 64 to be pressed inside the clamping ring 61, so that the linkage sealing mechanism 6 automatically and synchronously forms a sufficient sealing structure on the surface of the side ring frame 23 and the external ring frame 1, and the inertia of the internal parts of the external ring frame 1, the side ring frame 12 and the side ring frame 23 is discharged. The mechanism 7 is correspondingly installed on the built-in positioning cylinder 53, the linkage sleeve 71 included in the inertial discharge mechanism 7 is sleeved on the surface of the built-in positioning cylinder 53, and the arc-shaped slide 72 included in the inertial discharge mechanism 7 is fixed on the linkage sleeve 71 and enters into the sealed lampshade 41 along the side wall of the sealed lampshade 41, a piston piece 1 73 is installed on the side of the linkage sleeve 71 close to the external threaded sleeve 52, and a piston piece 2 75 is installed on the side of the arc-shaped slide 72 extending to the inside of the sealed lampshade 41, and a counterweight plate 7 is installed between the linkage sleeve 71 and the arc-shaped slide 72. 4, the inertia discharge mechanism 7 is affected by the inertia. When the piston piece 1 73 is displaced by the forward inertia, it will drive the linkage sliding sleeve 71 and the arc-shaped sliding frame 72 to move, and the counterweight piece 74 and the piston piece 2 75 will move inside the sealed lampshade 41 and the embedded sealing cylinder 51 respectively, and form air thrust. The piston piece 2 75 discharges the humid air inside the sealed lampshade 41 into the external lampshade 42 along the output hole structure of the conical cylinder structure of the sealed lampshade 41, and the counterweight piece 74 discharges the humid air inside the external ring frame 1 and the embedded sealing cylinder 51 along the side The embedded pipe groove structure installed on the ring frame 1 2 is squeezed into the external lamp cover 42, and the sealed lampshade 41 and the external lamp cover 42 are displaced due to inertia, driving the discharge hole structure of the external lamp cover 42 to separate from the fitting ring structure of the external ring frame 1, forming a dredging state, so that the humid air can be discharged. When the inertia is eliminated, the piston plate 2 75 is retracted and reset due to the reset spring structure installed between the embedded sealing cylinder 51, and the discharge hole structure of the external lamp cover 42 is also closed after the sealed lampshade 41 and the external lamp cover 42 are retracted and reset, until the vehicle brakes and starts again to generate inertia.
