[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-3 This utility model provides an embodiment of a waterproof sealing structure for a motorcycle LED headlight, comprising a base 1, a lampshade 3 connected above the base 1, a movable seat 2 connected below the base 1, and a sealing mechanism 5 provided on the base 1 and the movable seat 2; the sealing mechanism 5 includes positioning rods 53, multiple positioning rods 53 are slidably connected to the surface of the base 1, the positioning rods 53 and the lampshade 3 are inserted into each other, a second spring 54 is connected to the positioning rods 53, the second spring 54 is connected to the inner wall of the base 1, and the second spring 54 is in a state of tensioning the positioning rods 53 under normal conditions; the sealing mechanism 5 also includes a positioning ring 51, the positioning ring 51 and the surface of the positioning rods 53 are in elastic contact; a groove is opened on the inner wall of the lampshade 3 to cooperate with the positioning rods 53, and a sealing ring 13 is movably connected in the groove.

[0018] Through the above technical solution, the sealing mechanism 5 can continuously clamp the sealing ring 13, so that there will be no gap between the sealing ring 13 and the lamp cover 3, thus preventing water from passing through. This avoids the problem that the sealing ring 13 will shrink and create gaps during long-term use, and water will flow into the lamp cover 3 through the gaps, causing damage to the LED headlight.

[0019] Please see Figure 2 The positioning ring 51 is fixedly connected to the center of the movable seat 2. The surface of the movable seat 2 is connected to the first spring 52, which is connected to the base 1. The base 1 has multiple strip grooves 6 that cooperate with the positioning rod 53. The positioning rod 53 is slidably connected in the strip grooves 6.

[0020] Please refer to Figure 2. The end of the positioning ring 51 near the positioning rod 53 is tapered, and the end of the positioning rod 53 near the positioning ring 51 is tapered and parallel to the surface of the positioning ring 51. The surface of the movable seat 2 is connected to a limit rod 56, which is located in the inner ring of the first spring 52. The first spring 52 always exerts a pushing force on the movable seat 2, causing the movable seat 2 to tend to move away from the positioning rod 53.

[0021] Please see Figure 2 The end of the positioning rod 53 is connected to a locking block 55, which extends into the slot opened in the lamp cover 3 and abuts against the sealing ring 13. A limit ring 4 is fixedly connected to the inner wall of the movable seat 2, and the base 1 is slidably connected between the limit ring 4 and the movable seat 2.

[0022] Through the above technical solution, the sealing mechanism 5 ensures that the locking block 55 on the positioning rod 53 always elastically abuts against the sealing ring 13, so that there is no gap between the sealing ring 13 and the lampshade 3, thereby ensuring the sealing performance. In addition, the sealing mechanism 5 also facilitates the quick installation and removal of the lampshade 3. The sealing principle of the sealing mechanism 5 is that the elastic force of the first spring 52 pushes the positioning ring 51 to a state away from the positioning rod 53. At this time, under the pulling force of the second spring 54, the locking block 55 on the positioning rod 53 always abuts against the sealing ring 13 inside the lampshade 3, so that the sealing ring 13 and the lampshade 3 are always tightly fitted. In addition, the locking block 55 also engages with the slot on the lampshade 3 to realize the installation and fixation of the lampshade 3. When it is necessary to remove the lampshade 3, by pulling the moving base 2 upward, the positioning ring 51 on the moving base 2 rises synchronously, so that the positioning ring 51 pushes the positioning rod 53 towards the center of the base 1, so that the locking block 55 disengages from the slot on the lampshade 3, thereby completing the removal of the lampshade 3.

[0023] Please see Figure 3 A connecting cover 7 is fixedly connected to the surface of the base 1. A locking block 55 passes through the connecting cover 7. The connecting cover 7 is used to limit the lampshade 3, so that the locking block 55 can accurately connect with the slot on the lampshade 3. A positioning cylinder 9 is fixedly connected to the surface of the connecting cover 7. An insert rod 8 is connected to the lampshade 3. The insert rod 8 and the positioning cylinder 9 are inserted into each other. The positioning cylinder 9 is square and the insert rod 8 is a square rod. By inserting the insert rod 8 and the positioning cylinder 9, the lampshade 3 is limited in the circumference, so that the lampshade 3 cannot rotate. This, together with the sealing mechanism 5, completes the final installation of the lampshade 3.

[0024] Please see Figure 3 The lampshade 3 is connected to a mounting plate 10 inside, and the plug rod 8 is fixedly connected to the mounting plate 10. The headlight 11 is installed on the mounting plate 10. The end of the lampshade 3 is tapered, and the lampshade 3 is also connected to a light-transmitting plate 12 inside.

[0025] Working principle: The installation process is as follows: First, insert the movable seat 2 and the base 1. Then, push the movable seat 2 upward. At this time, the positioning ring 51 on the movable seat 2 pushes the positioning rod 53 to move until the locking block 55 on the positioning rod 53 no longer restricts the lampshade 3 and the connecting cover 7 from engaging. At this time, insert the lampshade 3 and the connecting cover 7. At the same time, the insertion rod 8 and the positioning cylinder 9 are inserted, thus completing the circumferential fixation of the lampshade 3. Then, slowly release the movable seat 2. At this time, under the action of the elastic force of the first spring 52, the positioning ring 51 on the movable seat 2 gradually moves away from the positioning rod 53. At this time, under the action of the tension of the second spring 54, the positioning rod 53 moves towards the lampshade 3 until the locking block 55 engages with the slot on the lampshade 3, and finally the installation of the lampshade 3 is completed. The sealing mechanism 5 not only ensures that the sealing ring 13 is always in contact with the lampshade 3 to ensure sealing, but also facilitates the installation and disassembly of the lampshade 3 and the base 1.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
