Description

Technical Field

[0001] This utility model relates to the field of laser lens technology, specifically a temperature- and corrosion-resistant laser lens assembly. Background Technology

[0002] A laser lens is an optical element used to focus or collimate a laser beam. It mainly consists of a laser diode and a lens at the rear of a vehicle. It can enhance lighting performance and is therefore widely used in automotive lighting systems to provide a longer lighting distance and clearer visual effect.

[0003] However, when a temperature- and corrosion-resistant laser lens assembly needs to be temporarily transported, the lenses in automotive headlight laser lens assemblies are usually convex lenses, which cause the lenses to protrude from the assembly's outer shell when placed. When the lenses are transported directly without protective packaging, they are prone to accidental bumps, which can cause the lenses to crack or become unusable, making temporary transport of laser lens assemblies inconvenient. In addition, after a long period of use, dirt or dust usually accumulates on the surface of the laser lens assembly through the outer casing. If it is not cleaned in time due to the difficulty of cleaning, the laser beam will be difficult to focus when passing through the lens, thus affecting the focusing effect of the lens assembly. Utility Model Content

[0004] The purpose of this invention is to provide a temperature- and corrosion-resistant laser lens assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature- and corrosion-resistant laser lens assembly, comprising an inner cylinder, with crossbars fixedly connected to both sides of the back of the inner cylinder, and a telescopic spring sleeved on the outer side of the crossbars; a laser lens mounted on the front of the inner cylinder; a cover provided on the outer side of the inner cylinder; a first opening on the front of the cover; a second opening at the top of the cover; a vertical plate slidably connected to the inner side of the second opening; a top plate provided at the top of the vertical plate; an insertion port provided at the top of the top plate; an insert plate movably embedded in the inner side of the insertion port; a cavity provided inside the vertical plate; sliding cylinders provided on both side walls of the cover; and a sponge pad provided on the back of the vertical plate.

[0006] Preferably, openings are provided at the four corners of the back of the inner cylinder, and the inner cylinder is connected to the laser diode cover by screws passing through the openings.

[0007] Preferably, the slide cylinder has a slide rail inside, and the crossbar is slidably connected to the slide cylinder through the slide rail.

[0008] Preferably, one end of the telescopic spring is fixedly connected to the back of the inner cylinder, and the other end of the telescopic spring is fixedly connected to the slide cylinder.

[0009] Preferably, the laser lens is inserted into the housing through the first opening, and the vertical plate is slidably connected to the first opening through the second opening.

[0010] Preferably, a first magnetic absorbing piece is provided on the front of the vertical plate, and a second magnetic absorbing piece is provided in the middle of the top of the cover. The first magnetic absorbing piece and the second magnetic absorbing piece are magnetically attracted to each other, and the vertical plate is magnetically attracted to the cover through the first magnetic absorbing piece.

[0011] Preferably, the bottom of the socket communicates with the interior of the cavity, one side wall of the sponge pad is located inside the cavity, and the sponge pad is slidably connected to the surface of the laser lens through a vertical plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This temperature- and corrosion-resistant laser lens assembly, through the design of a housing, vertical plate, telescopic spring, and inner cylinder, allows for temporary transport of the lens assembly. First, the housing is pulled away from the inner cylinder, causing the lens to retract into the housing. Simultaneously, the vertical plate is inserted through the second opening, blocking the first opening. At this point, the housing, under the action of the telescopic spring, presses the vertical plate against the front end of the lens, thus protecting the laser lens on the assembly and facilitating temporary transport of the laser lens assembly.

[0014] 2. This temperature and corrosion resistant laser lens assembly, through its insert plate, socket, cavity, and sponge pad, allows the lens to be adjusted to a protected state by the vertical plate when maintenance is required after use. At this time, the sponge pad on the side wall of the vertical plate will be in contact with the lens surface. Then, anhydrous alcohol can be poured into the cavity through the socket at the top of the horizontal plate, allowing the anhydrous alcohol to permeate through the sponge and coat the lens surface, dissolving dirt or dust on the lens surface. This facilitates timely cleaning of the lens surface and reduces adverse effects on the lens's focusing effect. Attached Figure Description

[0024] like Figures 1 to 5As shown, the temperature and corrosion resistant laser lens assembly of this embodiment includes an inner cylinder 1. Crossbars 3 are fixedly connected to both sides of the back of the inner cylinder 1. A telescopic spring 4 is sleeved on the outer side of the crossbars 3. A laser lens 13 is installed on the front of the inner cylinder 1. A cover 6 is provided on the outer side of the inner cylinder 1. A first opening 7 is opened on the front of the cover 6. A second opening 14 is opened at the top of the cover 6. A vertical plate 8 is slidably connected to the inner side of the second opening 14. A top plate 10 is provided at the top of the vertical plate 8. An insertion port 15 is opened at the top of the top plate 10. An insertion plate 11 is movably embedded inside the insertion port 15. A cavity 16 is opened inside the vertical plate 8. Sliding cylinders 5 are provided on both side walls of the cover 6. A sponge pad 17 is provided on the back of the vertical plate 8.

[0025] Specifically, the internal hollowing of the inner cylinder 1 allows sufficient space for the laser diode 19 to be installed and close to the laser lens 13 at the end of the inner cylinder 1, thereby concentrating the beam emitted by the laser diode 19 by the laser lens 13 assembly. The crossbar 3 ensures greater stability for the cover 6 as it slides along the inner cylinder 1. The telescopic spring 4 maintains the connection between the cover 6 and the inner cylinder 1, and returns to its initial state where the laser lens 13 passes through the first opening 7 on the front of the cover 6 after no external force is applied. The diameter of the first opening 7 matches the diameter of the laser lens 13, allowing the laser lens 13 to protrude normally from the front of the cover 6 during use. The inner width of the second opening 14 matches the outer width of the vertical plate 8, allowing the vertical plate 8 to... The vertical plate 8 slides vertically into the housing 6 through the second opening 14, thus shielding and protecting the laser lens 13 retracted into the housing 6. The outer width of the top plate 10 is greater than that of the vertical plate 8, so that the vertical plate 8 can be easily pulled out from the top of the housing 6, making it easy to separate the vertical plate 8 from the housing 6. The function of the insertion port 15 is to engage with the insertion plate 11, so that the top of the top plate 10 can be opened, making it easy to add anhydrous alcohol into the cavity 16 of the vertical plate 8 through the insertion port 15. The function of the cavity 16 is to contain anhydrous alcohol. The function of the sponge pad 17 is to absorb anhydrous alcohol and then let the anhydrous alcohol pass through to the surface of the laser lens 13, thereby achieving contact between the anhydrous alcohol and the surface of the laser lens 13, and thus achieving the dissolution and cleaning of dirt on the surface of the laser lens 13 by the anhydrous alcohol.

[0026] Furthermore, openings 2 are provided at the four corners of the back of the inner cylinder 1. The inner cylinder 1 is connected to the laser diode 19 by screws passing through the openings 2. The function of the openings 2 is to enable the inner cylinder 1 to be connected and fixed to the laser diode 19, thereby realizing the assembly and fixation of the laser lens 13 assembly.

[0027] Furthermore, a slide rail 18 is provided inside the slide cylinder 5, and the crossbar 3 is slidably connected to the slide cylinder 5 through the slide rail 18, so that the crossbar 3 can pass through both sides of the cover 6, thereby facilitating the cover 6 to slide stably along the surface of the inner cylinder 1.

[0028] Furthermore, one end of the telescopic spring 4 is fixedly connected to the back of the inner cylinder 1, and the other end of the telescopic spring 4 is fixedly connected to the slide cylinder 5, so that the cover 6 can always maintain a connection with the inner cylinder 1, thereby facilitating the subsequent reset of the cover 6.

[0029] Furthermore, the laser lens 13 is inserted and connected to the housing 6 through the first opening 7, and the vertical plate 8 is slidably connected to the first opening 7 through the second opening 14, so that the laser lens 13 can pass through the housing 6 through the first opening 7, and at the same time, the laser lens 13 can be retracted into the housing 6 through the first opening 7 for protection, thereby facilitating the temporary transportation of the laser lens 13 assembly.

[0030] Furthermore, a first magnetic clasp 9 is provided on the front of the vertical plate 8, and a second magnetic clasp 12 is provided in the middle of the top of the cover 6. The first magnetic clasp 9 and the second magnetic clasp 12 are magnetically attracted to each other. The vertical plate 8 is magnetically attracted to the cover 6 through the first magnetic clasp 9. The first magnetic clasp 9 can be magnetically attracted to the second magnetic clasp 12, so that the vertical plate 8 can be attracted to the top of the cover 6 when not in use, thus facilitating the subsequent removal and use of the vertical plate 8.

[0031] Furthermore, the bottom of the socket 15 is connected to the interior of the cavity 16, and one side wall of the sponge pad 17 is located inside the cavity 16. The sponge pad 17 is slidably connected to the surface of the laser lens 13 through the vertical plate 8. The function of the sponge pad is to absorb the anhydrous alcohol entering the cavity 16, so that the anhydrous alcohol can pass through the sponge pad 17 and contact the surface of the laser lens 13, thereby achieving the cleaning of the surface of the laser lens 13 by the anhydrous alcohol.

[0032] The method of use in this embodiment is as follows: When it is necessary to temporarily transport the temperature-resistant and corrosion-resistant laser lens 13 assembly, the cover 6 can be pulled outward first, so that the laser lens 13 on the front of the inner cylinder 1 is retracted into the cover 6 through the first opening 7. Then, the vertical plate 8 can be inserted from the second opening 14 at the top of the cover 6, so that the side of the vertical plate 8 with the sponge pad 17 faces the laser lens 13. While the cover 6 is pulled outward, the telescopic spring 4 will be stretched and deformed under force. When the top plate 10 at the top of the vertical plate 8 is attached to the top of the cover 6, the cover 6 can be released. At this time, the telescopic spring 4 will retract, so that the cover 6 together with the vertical plate 8 moves to the back of the inner cylinder 1. At this time, the vertical plate 8 The sponge pad 17 on the top plate 10 will fit against the surface of the laser lens 13 on the front of the inner cylinder 1. When it is necessary to clean the laser lens 13, the top plate 11 of the top plate 10 can be pulled out, so that the insertion port 15 at the top of the top plate 10 is exposed. Then, anhydrous alcohol can be added into the cavity 16 of the vertical plate 8 through the insertion port 15, so that the anhydrous alcohol passes through the sponge pad 17 and reaches the surface of the laser lens 13. Then, the top plate 10 can be pulled up and down, so that the vertical plate 8 drives the sponge pad 17 to move up and down along the surface of the laser lens 13, so that the sponge pad 17 wipes and cleans the surface of the laser lens, so that the dirt and dust on the surface of the laser lens can be cleaned in time.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
