Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0034] Please refer to Figure 1-8 , the above technical solutions of the present utility model are described in detail through the following embodiments:
[0035] A flashlight waterproof toggle switch structure comprises a pressing plate 1, a switch bracket 6 is fixedly arranged on one side of the pressing plate 1, a toggle switch 2 is movably arranged between the pressing plate 1 and the switch bracket 6, springs 5 are symmetrically arranged on both sides of the toggle switch 2, a group of push rods 4 are movably arranged on the back of the toggle switch 2, and O-rings 3 are sleeved on the push rods 4, a switch PCB board 8 is arranged on the back of the switch bracket 6, and screws 9 are threadedly connected at both upper and lower ends of the switch PCB board 8. The switch PCB board 8 can be fixed on the switch bracket 6 by the screws 9. By arranging the switch bracket 6 on the toggle switch 2 and Two spring sheets 5 are arranged on both sides of the switch 2, and the second protrusion 51 on the spring sheet 5 cooperates with the shift switch 2 to realize the sense of being in place when the shift switch 2 is pushed. The switch PCB board 8 with the light touch switch 81 is fixed under the switch bracket 6. When the shift switch 2 is pushed, the third protrusion 25 of the shift switch 2 in contact with the push rod 4 will push the push rod 4 to move laterally in the slide groove 64, thereby triggering the light touch switch 81. There are two light touch switches 81 on the switch PCB board 8. Pushing the shift switch 2 up or down triggers one gear each, and pushing it to the middle is one gear, thereby realizing multi-gear control of the entire device.
[0036] Furthermore, the shift switch 2 includes a pushing block 21, a first connecting block 22 is fixedly provided on the pushing block 21, a second connecting block 23 is fixedly provided on one side of the first connecting block 22, a group of first protrusions 24 are fixedly provided on both sides of the first connecting block 22, a second protrusion 51 is fixedly provided on the spring sheet 5, and the second protrusion 51 is embedded between the two first protrusions 24. The first protrusion 24 on the shift switch 2 and the second protrusion 51 on the spring sheet 5, plus the shift switch 2, cooperate to achieve a sense of being in place when pushing the shift switch 2.
[0037] It should be noted that a through hole is opened in the middle of the pressure plate 1 , and the push block 21 is located inside the through hole and protrudes outward, so as to facilitate manual operation of the shift switch 2 .
[0038] It should be noted that the second connecting block 23 is an L-shaped plate.
[0039] Furthermore, a square groove 61 is provided inside the switch bracket 6 , and the shift switch 2 is slidably arranged in the square groove 61 . By providing the square groove 61 inside the switch bracket 6 , space can be provided for the shift switch 2 to slide.
[0040] Furthermore, annular grooves 62 are symmetrically provided on both sides of the square groove 61, and bends 52 are fixedly provided at the upper and lower ends of the spring piece 5. The spring piece 5 is located in the annular groove 62, and the bend 52 abuts against the groove wall of the annular groove 62. By providing the bend 52 on the spring piece 5 and utilizing the elasticity of the spring piece 5 and the bend 52 themselves, the stability of the spring piece 5 in the annular groove 62 can be ensured.
[0041] It is worth noting that the square groove 61 and the annular groove 62 are connected to each other.
[0042] Further, an inner groove 63 is formed at the rear side of the square groove 61. The second connecting block 23 is clamped inside the inner groove 63. A third convex block 25 is fixedly arranged on the second connecting block 23. The third convex block 25 is located on the side opposite to the push rod 4. By arranging the third convex block 25 on the second connecting block 23, when the third convex block 25 where the shift switch 2 contacts the push rod 4 pushes the push rod 4 to move horizontally, the touch switch 81 is triggered accordingly.
[0043] It should be noted that a third convex block 25 is arranged at both the upper and lower ends of the second connecting block 23. The upper third convex block 25 is located at the lower end of the push rod 4, and the lower third convex block 25 is located at the upper end of the push rod 4.
[0044] Further, a sliding groove 64 is formed on the groove wall on one side of the inner groove 63. The push rod 4 is slidably arranged in the sliding groove 64. By arranging the sliding groove 64 on the groove wall of the inner groove 63, when the shift switch 2 is pushed, the third convex block 25 where the shift switch 2 contacts the push rod 4 will push the push rod 4 to move horizontally in the sliding groove 64.
[0045] It is worth noting that a touch switch 81 is fixedly arranged at both the upper and lower ends of the switch PCB board 8. The two touch switches 81 and the two push rods 4 are on the same horizontal line and do not contact each other.
[0046] Further, a sealing ring 7 is fixedly sleeved on the periphery of the switch bracket 6. By arranging the sealing ring 7, the whole switch can achieve a waterproof effect.
[0047] Working principle:
[0048] When the waterproof toggle switch structure of the present utility model is in use, first, the shift switch 2 is manually pushed upward, so that the shift switch 2 moves upward in the square groove 61 in the switch bracket 6. At the same time, the upper third convex block 25 on the second connecting block 23 moves upward. The upper third convex block 25 contacting the push rod 4 will push the upper push rod 4 to move horizontally in the sliding groove 64, thereby triggering the upper touch switch 81, and the device completes the gear control at the uppermost position; similarly, by manually pushing the shift switch 2 downward, the second convex block 51 on the elastic sheet 5 and the shift switch 2 cooperate to realize the in-place feeling when the shift switch 2 is pushed, and pushing to the middle is one gear; finally, by manually continuing to push the shift switch 2 downward, the lower third convex block 25 on the second connecting block 23 moves downward. The lower third convex block 25 contacting the push rod 4 will push the lower push rod 4 to move horizontally in the sliding groove 64, thereby triggering the lower touch switch 81, and further the device completes the gear control at the lowermost position.
[0049] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model, and are not used to limit the present utility model.
