Description

Technical Field

[0001] This invention belongs to the field of lighting technology, and in particular discloses a housing for automotive lamps. Background Technology

[0002] Car lights are essential components for nighttime driving. Cars often need to drive through water, and if the lights are not properly sealed, moisture can easily enter and condense on the inner wall of the lamp cover, affecting the lighting effect.

[0003] In existing technologies, drying inside lamps generally involves sealing or using desiccants to prevent moisture from entering. For example, CN110486691A discloses a fully enclosed moisture-proof automotive lamp device, relating to the fields of automotive electronics and automotive lighting. In this invention: a desiccant box is placed inside the first main mounting slot; a main sealing cover for sealing the first main mounting slot is installed on the open side of the first main mounting slot; one side of the desiccant box is suction-fitted onto the main sealing cover; a breathing adjustment outlet is provided on the lamp housing; a breathing lung structure is sealed and installed on the breathing adjustment outlet; an airtightness detection hole cover is provided on the lamp housing to block the airtightness detection hole; a bent inner limiting elastic plate is provided between a pair of inner rubber fixing plates; and a desiccant pack is placed inside the cavity of the first box. This invention makes the lamp fully enclosed, preventing the internal air from interacting with the outside environment and keeping the internal air dry. When the internal air is dry, even if the mask cools suddenly, no moisture in the internal air can condense on the mask.

[0004] The aforementioned existing technology uses desiccant packs and sealing methods to prevent the lampshade from fogging up.

[0005] In the aforementioned prior art, there is a problem that moisture cannot be removed after the sealing components of the desiccant in the desiccant package have aged and failed. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to disclose a vehicle lamp housing, which is achieved using the following technical solution.

[0007] A vehicle lamp housing includes a lamp cover and a front housing; The front housing includes a front housing body. A circular snap-fit ​​interface is provided on the left side of the front housing body. The lampshade is sealed and snap-fitted to the snap-fit ​​interface. The inner wall of the front housing body is a smooth spherical arc surface. The inner wall of the lampshade is a smooth spherical arc surface, and the outer edge of the lampshade is fitted with the card interface. The lampshade and front housing body are equipped with at least three wiping components that can move along the spherical arc surface where the inner wall of the lampshade is located; After all the erasing components are combined, the outer walls of all the erasing components completely overlap with the inner walls of the lampshade.

[0008] The aforementioned automotive lamp housing includes a mounting base fixed inside the main body of the front housing. A connecting component is located at the left end of the mounting base. A wiping device is mounted on the mounting base. The wiping device includes at least three wiping components, a push rod motor, gears of the same number as the wiping components, and a movable component. The wiping components and gears correspond one-to-one and are fixedly connected by a support component. The movable component includes a number of straight bases of the same number as the wiping components. All bases are arranged in a ring at equal intervals around the axis of the movable component. The bases are positioned away from the movable component by a certain distance. A rack is provided on each side, which meshes with a corresponding gear. A gear shaft is provided on the axis of the gear, and the gear shaft and the gear are rotatably connected. All gear shafts are fixed to each other to form a gear shaft group. The right end of the moving part is fixed to the end of the telescopic rod of the push rod motor. The push rod motor is mounted on the mounting base. The gear shaft group is fixed to the connecting part. When the push rod motor retracts to its limit, all the wiping parts merge in pairs, and the outer wall of all the wiping parts completely overlaps and fits tightly with the inner wall of the lamp cover. When the push rod motor extends to its limit, all the wiping parts separate and are located in the front housing body.

[0009] In the aforementioned automotive lamp housing, after the lamp cover is snapped and fixed to the front housing body via a snap-fit ​​interface, the inner wall of the lamp cover and the inner wall of the front housing body are located on the same spherical arc surface. When the wiping component is located inside the front housing body, the outer wall of the wiping component is in contact with the inner wall of the front housing body.

[0010] The outer surface of the wiping component of the aforementioned automotive lamp housing is made of absorbent felt.

[0011] The aforementioned automotive lamp housing has multiple inwardly protruding squeezing rings on the inner wall of the front housing body, and the squeezing rings are coaxial with the card interface.

[0012] The aforementioned automotive lamp housing has a drainage hole at the bottom of the front housing body. When the wiping component squeezes and passes over the squeezing ring, the squeezing ring squeezes out the water adsorbed by the wiping component. The water moves along the squeezing ring under gravity and is discharged through the drainage hole.

[0013] The aforementioned automotive lamp housing has a wire harness hole in its movable part for placing the wire harness connecting the lamp beads.

[0014] The aforementioned automotive lamp housing has a lamp holder at the left end of the movable part for mounting lamp beads.

[0015] The aforementioned automotive lamp housing has a mounting opening on the right side of the front housing body, and a rear housing is provided on the mounting opening, with a mounting base fixed to the rear housing.

[0016] The aforementioned automotive lamp housing has a positioning component on the side wall of the rear housing body. The positioning component is used to position the rear housing against the vehicle body, facilitating installation.

[0017] The aforementioned automotive lamp housing has mounting ears on the outer wall of the mounting opening.

[0018] This application has the following beneficial effects: 1. In this application, a wiping component is provided inside the lamp. The wiping component can move close to the inner wall of the lampshade to wipe away the moisture adhering to the inner wall of the lampshade, so that the light emitted by the lamp is brighter and the lighting effect is better.

[0019] 2. An erasing device is provided. When the push rod motor extends to its limit, the five erasing components are located inside the front housing body and will not affect the lighting effect of the lamp.

[0020] 3. The water-squeezing ring and drainage hole can quickly drain water and prevent water from accumulating over time, which would reduce the lifespan of the LED beads and the lamp circuit.

[0021] 4. When the push rod motor retracts to its limit, the outer wall of the five wiping parts completely overlaps and adheres tightly to the inner wall of the lampshade. In other words, a single wiping action can complete the wiping of moisture from the entire inner wall of the lampshade, resulting in high wiping efficiency and no dead corners.
