[0024] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.
[0025] In the following description, many specific details are set forth in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0026] Secondly, the present utility model will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present utility model, for the sake of convenience of description, the cross-sectional views showing the device structure will be enlarged locally out of the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.
[0027] Furthermore, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively exclusive embodiment with other embodiments.
[0028] Embodiment 1
[0029] Refer to Figure 1 - Figure 6, this embodiment provides a split-type wire spring manual mirror anti-glare adjustment structure, including a transfer component 100. The transfer component 100 includes an adjustment base 101, an adjustment knob 102 that cooperates with the adjustment base 101, a clamping member 103 connected to the adjustment base 101, and a mirror housing 104 connected to the adjustment base 101. On both sides of the adjustment knob 102, there are respectively fixed connection rods 102a, and a wire spring 102b is arranged between the two connection rods 102a.
[0030] As Figure 1 and Figure 6 shown, the wire spring 102b is fixed in the positioning groove opened on the adjustment base 101 by a clamping method, with both ends protruding from the side of the adjustment base 101. There are two connection rods 102a on both sides of the adjustment knob 102, and both ends of the wire spring 102b are placed between the two connection rods 102a. When the adjustment knob 102 rotates, the connection rods 102a will move the wire spring 102b in opposite directions. Since the wire spring 102b is installed on the adjustment base 101, when the wire spring 102b moves, it will cause the adjustment base 101 to rotate along the axis of the U-shaped card slot, making the entire lens rotate accordingly.
[0031] Furthermore, the clamping member 103 includes a ball bowl 103a and a pinch spring 103b. The ball bowl 103a is installed on one side of the adjustment base 101, and the pinch spring 103b is installed outside the ball bowl 103a.
[0032] Furthermore, the inner diameter of the pinch spring 103b is smaller than the outer diameter of the ball bowl 103a, and the outer diameter of the ball bowl 103a in the direction away from the adjustment base 101 is larger than the outer diameter at the connection with the adjustment base 101.
[0033] It should be noted that the pinch spring 103b is fixedly connected to the outside of the ball bowl 103a, which plays a role in tightening the ball bowl to prevent the ball head from falling off. It is also possible to control the force value of the ball bowl 103a wrapping the ball head by adjusting the inner diameter size of the pinch spring 103b, solving the problem that the force of the ball bowl wrapping the ball head decreases at high temperatures.
[0034] In addition, the pinch spring 103b is an annular metal product.
[0035] Furthermore, the position where the ball bowl 103a is fixedly connected to the adjustment base 101 is annular, and the shape of the ball bowl 103a in the position away from the adjustment base 101 is a four-lobe structure.
[0036] It should be noted that the ball bowl 103a is divided into four lobes, solving the problem of the ball bowl cracking when installing the ball head in the past, and solving the problem that the base needs to be baked to soften it before assembling the ball head in the past.
[0037] Furthermore, on both sides of the adjustment base 101, there are respectively fixedly connected first shaft rods 101a.
[0038] Furthermore, a second shaft rod 101 b is fixedly connected to the top of the adjustment base 101 , and the second shaft rod 101 b is located below the first shaft rod 101 a .
[0039] Furthermore, the adjustment base 101 and the adjustment knob 102 are split structures, and a wire spring 102b matching structure is arranged between the adjustment base 101 and the adjustment knob 102. Due to the rigidity and elasticity of the wire spring 102b, the problem of abnormal noise in the adjustment structure caused by plastic softening in a high temperature environment and a significant reduction in the force required to turn the knob 102 is effectively solved, thereby improving the product stability.
[0040] When in use, the ball head is inserted into the ball bowl 103a, and the pinch spring 103b outside the ball bowl 103a will tighten the four-petal structure of the ball bowl 103a inward, solving the problem of reduced force of the ball bowl wrapping the ball head at high temperature. It has a simple structure and is easy to assemble, which improves product assembly efficiency, saves product costs, and has better practicality.
[0041] Example 2
[0042] Reference Figure 1 - Figure 6 Based on the previous embodiment, this embodiment provides a split wire spring manual mirror anti-glare adjustment structure, wherein a first mounting groove 104a is opened on the inner side of the mirror housing 104, and the first shaft rod 101a and the second shaft rod 101b are both matched with the first mounting groove 104a.
[0043] Furthermore, a second mounting groove 104 b is formed inside the mirror housing 104 , and the lever 102 a is located in the second mounting groove 104 b .
[0044] It should be noted that the first mounting groove 104a and the second mounting groove 104b are both U-shaped grooves, the adjusting base 101 and the adjusting knob 102 are installed inside the mirror housing 104, and the installation method is a U-shaped groove on the mirror housing 104, the second shaft rod 101b and the first shaft rod 101a on both sides of the adjusting base 101 and the adjusting knob 102 are stuck inside the U-shaped groove and cannot be disengaged, but can be rotated along the axis of the U-shaped groove, the adjusting knob 102 cylinder is between the levers 102a, and the adjusting knob 102 and the adjusting base 101 are separate and independent two The upper end of the adjusting base 101 is installed in the U-shaped slot in the upper part of the mirror housing 104, and the adjusting knob 102 is installed in the U-shaped slot in the lower part of the mirror housing. The distance between the upper and lower U-shaped slots is smaller than the distance between the adjusting base 101 and the adjusting knob 102 cylinders. After installation, the adjusting knob 102 and the adjusting base 101 will be squeezed inward by the mirror housing 104, so that the adjusting base 101 and the adjusting knob 102 will not fall off or make abnormal noises. The distance between the upper and lower U-shaped slots can also be adjusted to adjust the force required for toggling.
[0045] In use, as Figure 2 shown, when the adjustment knob 102 is toggled to one side, the adjustment knob 102 rotates along the first shaft rod 101a to one side. At the same time, an opposite force is generated at the position of the first shaft rod 101a. Since the adjustment knob 102 and the adjustment base 101 are separate and the lens is mounted on the connecting shaft 105 which is stationary, when the adjustment base 101 rotates, the lens will also rotate by a certain angle. When the adjustment knob 102 rotates, the lever 102a will move the wire spring 102b in the opposite direction. Since the wire spring 102b is mounted on the adjustment base 101, when the wire spring 102b moves, it will cause the adjustment base 101 to rotate along the axis of the first mounting groove 104a, causing the entire lens to rotate accordingly, thereby changing the angle of the reflected light.
