[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4This invention provides a single-beam lens module for automobiles that is less prone to fogging. It includes an end cap 1 and a lens 2 housed within the end cap 1. The end cap 1 is detachably connected to a lens bracket 3 via a threaded connection. Rotating the end cap 1 facilitates connection and separation from the lens bracket 3. The end cap 1 contains a sealing gasket 10 and a sealing surface 11. When the lens 2 is in its positioned state, the lens bracket 3 applies a forward thrust to the lens 2. Combined with the sealing gasket 10 and sealing surface 11, a double sealing effect is achieved, effectively preventing moisture from entering and providing a good anti-fogging effect.
[0022] When installing lens 2, insert lens 2 into end cap 1, with the end face of lens 2 protruding from end cap 1. Then rotate end cap 1 to connect with lens bracket 3. End cap 1 gradually moves closer to lens bracket 3, and the end of end cap 1 slides relative to positioning post 4. When end cap 1 is connected to lens bracket 3, positioning post 4 is aligned with positioning groove 13. The compressed spring 9 pushes positioning post 4 forward, connecting positioning post 4 with positioning groove 13, thus limiting the end cap 1. At this time, the end of lens bracket 3 presses against lens 2, facilitating the positioning and fixing of lens 2 and improving the stability of lens 2 installation.
[0023] An annular groove 14 is provided inside the end cap 1. The annular groove 14 matches the sealing gasket 10. The sealing gasket 10 is made of rubber material and is placed inside the annular groove 14. When the lens 2 is disassembled, it is convenient to replace the sealing gasket 10.
[0024] The sealing surface 11 is an annular bevel, and the sealing surface 11 is provided with a positioning protrusion 15 for limiting the lens 2. The lens 2 is provided with a notch, which matches the positioning protrusion 15. When the lens 2 is installed into the end cover 1, the notch connects with the positioning protrusion 15 to initially limit the lens 2 and prevent rotation.
[0025] The lens holder 3 is connected to a positioning mechanism for positioning the end cap 1. The positioning mechanism includes a positioning post 4, a smooth surface 5, a pushing block 6, a rectangular hole 7, a guide groove 8, and a spring 9. The guide groove 8 and the rectangular hole 7 are located on the lens holder 3, and the guide groove 8 is connected to the rectangular hole 7. The guide groove 8 is used to guide the positioning post 4. The smooth surface 5 is located at the end of the positioning post 4. The spring 9 is located in the guide groove 8, and both ends of the spring 9 are connected to the positioning post 4 and the lens holder 3. The pushing block 6 is used to drive the positioning post 4 to reciprocate. When the end cap 1 gradually moves closer to the lens holder 3, the end of the positioning post 4 slides relative to the end cap 1, that is, the smooth surface 5 slides relative to the end cap 1, which can reduce the contact friction and make the rotation of the end cap 1 easier. During the forward movement of end cap 1, positioning post 4 is gradually inserted into guide groove 8, and spring 9 is gradually compressed until end cap 1 is connected to lens bracket 3. At this time, end cap 1 stops moving forward. Positioning post 4 is aligned with positioning groove 13. The compressed spring 9 pushes positioning post 4 to move, so that positioning post 4 is connected to positioning groove 13, thereby limiting and fixing end cap 1. The operation is simple and convenient.
[0026] The end cap 1 is provided with a positioning groove 13, which matches the positioning post 4. The positioning post 4 is slidably connected to the guide groove 8, which improves the stability of the reciprocating movement of the positioning post 4 and plays a good guiding role.
[0027] The push block 6 is fixedly connected to the positioning post 4, and the push block 6 is slidably connected to the rectangular hole 7.
[0028] Working principle: Lens 2 is inserted into end cap 1, connecting the notch on lens 2 with positioning protrusion 15, initially limiting the position of lens 2. Then, end cap 1 is rotated to connect with lens support 3. End cap 1 gradually moves closer to lens support 3, and the smooth surface 5 at the end of positioning post 4 slides relative to end cap 1, gradually inserting positioning post 4 into guide groove 8, while spring 9 is gradually compressed. Until end cap 1 is connected to lens support 3, end cap 1 stops rotating, positioning post 4 is aligned with positioning groove 13, and the compressed spring 9 pushes positioning post 4 to move, connecting positioning post 4 with positioning groove 13, thereby limiting the position of end cap 1 and improving the stability of the connection between end cap 1 and lens support 3. At the same time, the end of lens support 3 is pressed against lens 2, and with the use of sealing gasket 10 and sealing surface 11, the sealing performance of the connection between lens 2 and end cap 1 is improved, effectively preventing the entry of external moisture and achieving an anti-fog effect. When lens 2 needs to be disassembled, push the push block 6 to move the positioning post 4, so that the positioning post 4 is separated from the positioning groove 13, and then rotate the end cover 1 to separate from the lens bracket 3, which facilitates the disassembly of lens 2 and also facilitates the replacement of the sealing gasket 10, making it highly practical.
