Description

Technical Field

[0001] This utility model relates to the field of vehicle camera technology, specifically a vehicle lens module barrel. Background Technology

[0002] With the rapid development of automotive electronics and security technologies, in-vehicle cameras have become an indispensable piece of hardware for traffic safety. Their ability to present video and audio in real time provides a more scientific basis for handling and locating traffic accidents, ensuring the safety of car owners' property and lives.

[0003] However, existing automotive lens module barrels, as proposed in a published patent (Publication No.: CN217879773U), present a dual-lens automotive lens module barrel. The inner wall of the barrel body has an internal thread on the side away from the threaded end cap, facilitating quick and easy installation of the barrel body to the automotive lens module. Simultaneously, a positioning internal thread is provided on the inner wall of the barrel body, allowing the installation of an inner lens, thus achieving dual-lens installation and fixation. However, the lenses may tilt during placement, rendering them unusable. This makes lens installation cumbersome, requiring multiple attempts, and removing tilted lenses may damage them. Therefore, this application provides an automotive lens module barrel to solve the problems mentioned in the background art. Summary of the Invention

[0017] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0018] refer to Figure 1 This is a structural diagram of the mounting cylinder 1. The bottom of the mounting cylinder 1 has an internal thread, which is used to fix the mounting cylinder 1 to the vehicle-mounted lens module. The upper end of the mounting cylinder 1 has an external thread. An end cap 12 is provided at the upper end of the mounting cylinder 1. The inner wall of the end cap 12 has an internal thread, which is threaded to the external thread on the mounting cylinder 1. A circular clamping member 13 is rotatably connected inside the end cap 12, forming a cavity with the end cap 12. Figure 3 (As shown).

[0019] like Figure 2 , Figure 4 As shown, the mounting cylinder 1 is equipped with a lifting mechanism inside. The lifting mechanism includes two sets of limiting grooves 2 on the inner wall of the mounting cylinder 1, which are symmetrically distributed. The limiting grooves 2 extend upward to the upper end of the mounting cylinder 1, without needing to penetrate the upper end of the mounting cylinder 1, thereby limiting objects sliding inside the limiting grooves 2 and preventing them from falling out of the mounting cylinder 1. A mounting plate 21 is fixedly installed inside the mounting cylinder 1 at the lower end of the limiting grooves 2. A support spring 22 is fixedly welded to the upper end of the mounting plate 21, and a lifting cylinder 23 is fixedly connected to the upper end of the support spring 22. The cylinder wall of the lifting cylinder 23 is fitted with the cavity formed by the pressure member 13 and the end cap 12. Two sets of limiting blocks 24 are fixedly installed at the bottom of the lifting cylinder 23, and the limiting blocks 24 are slidably connected inside the limiting grooves 2. A sliding groove 25 is provided on the cylinder wall of the lifting cylinder 23, which penetrates the lifting cylinder 23 upward. The lifting cylinder 23 has two sets of sliding grooves 25, which are symmetrically distributed. A lens is placed inside the lifting cylinder 23, including a first lens 26 and a second lens 27. Multiple washers 28 are placed inside the lifting cylinder 23, and are respectively positioned on the upper and lower end faces of the first lens 26 and the second lens 27, thereby protecting the first lens 26 and the second lens 27.

[0020] In a specific embodiment, after clamping the upper and lower ends of the washer 28 with tweezers, the washer 28 is placed into the interior of the lifting cylinder 23 along the sliding groove 25. Then, using tweezers again, the first lens 26, the second lens 27, and the remaining two washers 28 are sequentially placed into the interior of the lifting cylinder 23 in the same manner. When clamping the lenses, please use tweezers with a rubber layer on the clamping part to prevent damage to the lenses. The end cap 12 is placed on the upper end of the mounting cylinder 1 and rotated clockwise. The end cap 12 moves downwards through the internal thread and the external thread at the upper end of the mounting cylinder 1, and the cylinder wall of the lifting cylinder 23 is in the cavity formed by the pressing member 13 and the end cap 12. When the end cap 12 moves downward, it drives the holding member 13 to move downward simultaneously, causing the holding member 13 to initially contact the washer 28 at the upper end of the second lens 27. The downward pressure applied by the end cap 12 is transmitted to the lifting cylinder 23 through the washer 28 and the lens. Since the holding member 13 is rotatably connected to the end cap 12 via a bearing, after the holding member 13 contacts the washer 28, it will not cause the washer 28 and the lens to rotate due to the downward pressure applied by the end cap 12. Because the lower end of the lifting cylinder 23 is connected to the support spring 22, the lifting cylinder 23 compresses the support spring 22 when it moves downward. The support spring 22 is a low-stiffness spring that is easily compressed, preventing the excessive reaction force generated by the support spring 22 when it is compressed downward from damaging the squeezed lens. Furthermore, when the lifting cylinder 23 moves downward, the limiting block 24 at the lower end slides on the limiting groove 2 on the inner wall of the mounting cylinder 1, preventing the lifting cylinder 23 from rotating during installation. The end cap 12 compresses the support spring 22 downwards to a tight state, ensuring that it cannot move up or down through the support spring 22. The support spring 22 fixes the lower end of the lifting cylinder 23, and the clamping member 13 fixes the upper end of the lifting cylinder 23 with the lens through the washer 28, and the clamping member 13 fixes the washer 28 and the lens inside the lifting cylinder 23.

[0021] When the lens needs to be replaced, rotate the end cap 12 counterclockwise. As the end cap 12 and the holding member 13 move upward, they slowly separate from the washer 28. At the same time, the pressure on the upper end of the support spring 22 decreases, and it begins to reset upward, lifting the lifting cylinder 23 upward. As the end cap 12 moves upward, the lifting cylinder 23 rises. When the end cap 12 is removed, the bottom of the sliding groove 25 of the lifting cylinder 23 is higher than the mounting cylinder 1 under the action of the support spring 22. Since the limiting block 24 can only move inside the limiting groove 2, the lifting cylinder 23 is prevented from falling off. The replacement method is the same as the installation method.

[0022] Working principle: The lens and washer 28 are sequentially placed into the lifting cylinder 23 via the slide groove 25 using tweezers. The end cap 12 is placed on the upper end of the mounting tube 1 and rotated clockwise. As the end cap 12 moves downward via its threads, it also drives the holding member 13 to move synchronously. During its downward movement, the holding member 13 contacts the washer 28 and applies downward pressure to the washer 28 and the lens. The holding member 13 moves the lifting cylinder 23 downward via the lens and the washer 28. During the downward movement of the lifting cylinder 23, the support spring 22 is compressed. When the support spring 22 is compressed to a tight state, the lens is fixed inside the lifting cylinder 23. Finally, it is fixed to the vehicle-mounted lens module via the internal threads at the bottom of the mounting tube 1. When maintenance is required, rotate the end cap 12 counterclockwise. When the end cap 12 moves upward, it drives the holding member 13 to move synchronously. When the holding member 13 moves upward slowly, it slowly separates from the washer 28. The support spring 22 begins to reset upward and lifts the lifting cylinder 23 upward. During the upward movement of the lifting cylinder 23, the limiting block 24 can only slide up and down inside the limiting groove 2 to prevent the lifting cylinder 23 from falling off the mounting cylinder. When the lifting cylinder 23 rises to the top, the bottom of the slide groove 25 is higher than the mounting cylinder 1. After removing the end cap 12, use tweezers to remove the washer 28 and the lens for replacement, thereby achieving quick lens replacement.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
