Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile lamps, in particular to a mounting waterproof structure of an automobile headlamp. BACKGROUND

[0002] The automobile headlamp is a core lighting component for driving at night and in bad weather, and the working environment thereof is complex and changeable, and the automobile headlamp needs to frequently cope with scenes such as rain, accumulated water and high humidity. Water or water vapor in the lamp will lead to a decrease in lighting effect, bulb damage and even circuit failure, and seriously affect driving safety. With the development of the automobile industry, the user's requirements for the water crossing ability of the vehicle and the durability of the parts are continuously improved.

[0003] At present, the lamp holder and the lampshade of the traditional automobile headlamp are connected by buckles and a single sealing ring. After long-term use, the buckles are prone to loosen due to vibration, and the sealing ring loses elasticity due to aging, so that rainwater seeps in from the gap. Although some devices are provided with drainage holes, they lack an active sealing mechanism. When the vehicle passes through a road surface with deep accumulated water, the water pressure is easy to break the sealing ring, and the passive waterproof component is easy to be blocked by mud and sand and fail, so that the water inlet channel cannot be reliably closed. In view of this, the application provides a mounting waterproof structure of an automobile headlamp. SUMMARY

[0009] Preferably, the inner wall of the horizontal cylinder is fixedly connected with a guide plate, the inner wall of the horizontal cylinder is threadedly connected with a cover plate, and the outer wall of the extension rod is slidably connected to the inner wall of the guide plate, so that the movement of the extension rod is guided by the guide plate.

[0010] Preferably, the adjusting assembly is provided with a sensing assembly, the sensing assembly comprises a vertical cylinder, and the inner wall of the vertical cylinder is fixedly connected with a supporting plate.

[0011] Preferably, the inner wall of the supporting plate is slidably connected with a sliding rod, the top of the sliding rod is fixedly connected with a synchronous plate, and the end of the sliding rod away from the synchronous plate is fixedly connected with a floating ball.

[0012] Preferably, the top of the synchronous plate is fixedly connected with a second sealing gasket, the lower portion of the floating ball is provided with a filter plate, the supporting plate is provided with a through groove, and the supporting plate and the synchronous plate are elastically connected through a spring.

[0014] Preferably, the lamp holder body is provided with a heating chamber, the heating chamber is provided with a third sealing groove, and the heating chamber is detachably connected with a quartz heating tube, so that the heating chamber is heated by the quartz heating tube, and the temperature of the internal space of the lamp holder body and the lampshade is increased.

[0015] Preferably, the lamp holder body is provided with a threaded hole, and four groups of threaded holes are arranged, so that the lamp holder body is fixed on the vehicle body by screws.

[0016] Preferably, the horizontal cylinder is provided with an access hole, a first chamber, a guide slot, a second chamber and a discharge hole, the mounting plate is fixed on the second chamber by screws, the guide plate is fixed on the guide slot by screws, the cover plate is threadedly connected on the second chamber, and the extension rod, the movable plate and the first sealing gasket are located in the first chamber.

[0017] Preferably, the vertical cylinder is provided with a butt joint hole, a third chamber, a fourth chamber and a filter slot, the vertical cylinder is welded on the outer wall of the horizontal cylinder, the discharge hole is aligned with the butt joint hole, the supporting plate is fixed on the fourth chamber by screws, the filter plate is fixed on the filter slot by screws, the floating ball is located in the fourth chamber, and the synchronous plate and the second sealing gasket are located in the third chamber.

[0018] The application provides a waterproof structure for installing an automobile headlamp.

[0019] (1) The installation waterproof structure of the automobile headlamp combines passive sealing and active sealing mechanism to form a comprehensive waterproof barrier. When the vehicle is wading, the float is driven by buoyancy, the synchronous plate is lifted through the sliding rod, the sealing gasket 2 is tightly attached to the inner wall of the third chamber, the docking hole is automatically closed, and the first passive protection is realized. If the water is deep or the float response is insufficient, the electric push rod can actively push the extension rod, the movable plate drives the sealing gasket 1 to close the access hole, and the second active protection is formed. The double sealing cooperative action can not only cope with sudden wading scenes, but also make up for the limitations of single sealing. Even in complex road conditions (such as water impact, road bumps), the inside of the headlamp can still be kept dry, fundamentally avoiding problems such as circuit short circuit and lamp cover fogging caused by water ingress, and significantly improving the reliability of the automobile headlamp in harsh environments.

[0020] (2) The installation waterproof structure of the automobile headlamp is designed to solve the problem of water vapor in the headlamp due to temperature difference. The quartz heating tube in the heating chamber can uniformly raise the temperature inside the lamp, accelerate the evaporation of water vapor, and avoid water droplets from condensing on the inner wall of the lampshade. At the same time, the moisture absorber package in the adsorption chamber continuously absorbs residual moisture through the through hole, forming a dynamic balance. This cooperative mechanism not only quickly eliminates the fog in the lamp, but also maintains a dry environment for a long time, especially suitable for high humidity areas or large temperature difference between day and night. Compared with the traditional design which only relies on ventilation, the dehumidification efficiency of this structure is significantly improved, which can ensure that the illumination clarity of the headlamp is not affected, and prolong the service life of the bulb and circuit elements.

[0021] (3) The installation waterproof structure of the automobile headlamp precisely guides the extension rod through the guide plate and the sliding rod through the support plate, making the sealing action smooth and avoiding sealing failure caused by component jamming. The adsorption seat is connected by screws, which can be easily replaced with a moisture absorber package, reducing maintenance costs. The filter plate can block mud and sand from entering the sensing assembly, ensuring the sensitivity of the float and the stability of the structure throughout the vehicle's life cycle.

[0041] In the present application, when used, first need to complete the installation and commissioning of the device: the lamp holder body 1 is fixed in the vehicle body by four sets of threaded holes 17 with screws, ensuring that the lamp holder body 1 is closely attached to the vehicle body, the horizontal cylinder 51 is connected with the butt joint 4 through threads, the filter plate 67 is installed in the filter slot 614 of the vertical cylinder 61 to prevent silt from entering the fourth chamber 613, the desiccant bag 10 is placed in the adsorption seat 9 of the adsorption chamber 7, and the adsorption seat 9 is fixed by screws.

After about 10-15 minutes, the fog can completely dissipate.

[0045] During regular maintenance, check whether the filter plate 67 is blocked, if there is sediment accumulation can be removed and cleaned or replaced; every 3-6 months open adsorption seat 9, replace the moisture absorbent bag 10 (moisture silica gel desiccant can be dried at 120 DEG C and reused); check whether the sealing gasket 56 and the sealing gasket 66 appear cracks or aging, if the elasticity decreases need to replace in time; test the running state of the electric push rod 53 and the quartz heating tube 16, ensure that the circuit connection is firm, avoid the influence of poor contact on the function.
