[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Example 1
[0032] like Figure 1-8 As shown, a car turn light control switch includes a handle assembly 1, a slider 2, a Hall sensor 3, a PCB board 4, and a magnet 5. The handle assembly 1 includes a handle 11 and a rotating cylinder 12 arranged at the end of the handle, the rotating cylinder 12 rotates around a rotating shaft 61 on a base assembly 6, and a driving rod 13 is arranged on one side of the outer side of the rotating cylinder 12, and a slide groove 14 is arranged on the driving rod 13. The slider 2 includes a sliding rod 21 and a rotating block. The lower end of the sliding rod 21 is inserted in the slide groove 14 and is slidably connected with the slide groove 14. The rotating block is connected to the upper end of the sliding rod 21, and one end of the rotating block is inserted in the rotating hole 71 of the rotating seat 7 and is rotatably connected to the rotating seat 7. The PCB board 4 is arranged below the rotating seat 7, the Hall sensor 3 is arranged on the PCB board 4, the magnet 5 is embedded in the rotating block, and is integrally formed with the slider 2 by insert injection molding. The structure is simpler and occupies less space. The magnet 5 cooperates with the Hall sensor 3 located directly below the rotating block. When turning on the turn signal, turn the handle 11, and the handle drives the driving rod 13 to rotate around the rotating shaft 61, so that the rotating block and the magnet 5 located inside the rotating block rotate around the rotating hole 71, and the Hall sensor 3 located below the magnet 5 detects the change in angle, thereby controlling the opening and closing of the left turn signal and the right turn signal; and the rotation angle of the handle 11 is amplified by the cooperation of the slider 2 and the driving rod 13, which is easy for the Hall sensor to sense. In this embodiment, the amplification factor is twice, that is, the handle rotates at an angle of + / -5°, which drives the magnet to rotate by + / -10°, which can reduce the rotation angle of the handle 11, thereby reducing the operating space of the control switch. In summary, the utility model has a simple structure, occupies a small space, and the control switch does not need to rub the PCB board, which solves the problem of friction noise, and can avoid wear on the PCB board, extending the service life.
[0033] In the above structure, if Figure 5-7As shown, a sensing rod 15 is also provided on one side of the outer side of the rotating drum 12. The sensing rod 15 is set at an angle with the driving rod 13. The sensing assembly 8 is provided on the sensing rod 15. The sensing assembly 8 includes a touch rod 81, a spring 82, and a sensing block 83. The spring 82 is provided in the sensing rod 15. The sensing block 83 is provided at the end of the sensing rod 15 away from the rotating drum 12, and the side close to the sensing rod 15 is a V-shaped surface; one end of the touch rod 81 is inserted in the sensing rod 15 and connected with the spring 82, and the other end extends out of the sensing rod 15 and abuts against the V-shaped surface of the sensing block 83. The touch rod 81 maintains abutment with the sensing block 83 under the action of the spring 82. When the handle 11 is in the middle position, the touch rod 81 is located in the middle of the V-shaped surface of the sensing block 83; when the handle 11 rotates upward or downward, it drives the sensing rod 15 to rotate, so that the touch rod 81 slides along the inclined surfaces on both sides of the V-shaped surface, forming an operating feel and a better experience.
[0034] In addition, if Figure 1-2 As shown in , 7, a handle seat 62 is also provided on the base assembly 6, and the rotating cylinder 12, driving rod 13 and sensing rod 15 of the handle assembly 1 are all arranged in the handle seat 62, and a guide cavity for guiding the movement of the sensing rod 15 is provided inside the handle seat 62 located on one side of the sensing rod 15; the handle seat 62 is a split structure, including an upper handle seat 621 and a lower handle seat 622, and the upper handle seat 621 and the lower handle seat 622 are connected by a snap buckle, with a simple structure and easy disassembly and assembly, so as to facilitate the installation of the handle assembly 1.
[0035] Example 2
[0036] Based on the structure of embodiment 1, wherein, Figure 3-6 As shown, the rotating block includes a positioning portion 22 and a rotating portion 23. The positioning portion 22 abuts against the top surface of the rotating seat 7. A stop boss 221 is provided on the top of the positioning portion 22. An easily formed process hole is provided on the stop boss 221 to facilitate the forming of the slider 2. A stop column is provided on the base assembly 6 and is located directly above the stop boss 221. The axial displacement of the rotating portion 23 is limited by the stop column and the top surface of the rotating seat 7, thereby avoiding the displacement of the slider 2. The rotating portion 23 is cylindrical and is located below the positioning portion 22. The rotating portion 23 is inserted into the rotating hole 71, and the magnet 5 is embedded in the rotating portion 23.
[0037] In the above structure, if Figure 4 , 8As shown, the outer circumference of the rotating part 23 is provided with a plurality of fan-shaped protrusions 231 evenly distributed around the circumference, and a protruding fan-shaped friction block 232 is provided in the middle of each fan-shaped protrusion 231, and the friction block 232 cooperates with the rotating hole 71. The area of each friction block 232 cooperating with the rotating hole 71 is small, and the cooperating area is not greater than 0.1 times the total area of the rotating hole, thereby greatly reducing the rotational friction between the rotating part 23 and the rotating hole 71, making the rotation of the rotating part 23 smoother, reducing wear, and extending the service life of the product. In this embodiment, the outer circumference of the rotating part 23 is divided by grooves to have three fan-shaped protrusions 231, which can facilitate the molding of the rotating part 23, and each friction block 232 is not greater than 1 / 3 of the fan-shaped protrusion 231, with low friction and wear. The slider 2 is made of wear-resistant plastic, specifically POM plastic. POM plastic has the characteristics of high hardness, high rigidity, and high wear resistance, especially excellent friction resistance, thereby extending the service life of the slider.
[0038] In addition, if Figure 4 As shown, the top surface of the rotating seat 7 is provided with an annular convex ring 72 located outside the rotating hole 71, the top surface of the annular convex ring is an arc surface, and the bottom surface of the positioning portion 22 abuts against the top surface of the annular convex ring 72. This arrangement can reduce the friction between the positioning portion 22 and the top surface of the rotating seat 7, further reduce wear, and extend the service life of the product.
[0039] In addition, if Figure 2 , 3 As shown, the rotating seat 7 is also provided with an arc-shaped groove 73 which is coaxial with the rotating hole 71. The upper end of the sliding rod 21 is inserted into the arc-shaped groove 73 and is slidably connected with the arc-shaped groove 73. This arrangement ensures that the rotation of the handle 11 drives the magnet 5 to rotate around the rotating hole 71 by a corresponding angle, thereby ensuring the detection accuracy of the Hall sensor 3.
