In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0026] 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 appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other from other embodiments.

[0027] Embodiment 1

[0028] Refer to Figure 1 - Figure 5 , this embodiment provides an integrated manual anti-glare adjustment structure with a pinch spring, including an adjustment assembly 100. The adjustment assembly 100 includes an adjustment base 101, an adjustment knob 102 connected to the adjustment base 101, a clamping member 103 connected to the adjustment base 101, and a lens housing 104 connected to the adjustment base 101.

[0029] It should be noted that the adjustment base 101 is connected to the adjustment knob 102, and the two are injection-molded together during injection molding, eliminating the subsequent splicing and installation process and solving the problem of frictional noise in a split structure in a low-temperature environment.

[0030] Furthermore, the clamping member 103 includes a ball bowl 103a and a snap spring 103b. The ball bowl 103a is installed on one side of the adjustment base 101, and the snap spring 103b is installed on the outside of the ball bowl 103a.

[0031] Furthermore, the inner diameter of the snap 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.

[0032] It should be noted that the snap spring 103b is fixedly connected to the outside of the ball bowl 103a, which serves to tighten the ball bowl and prevent the ball head from falling off. It is also possible to control the force value of the ball bowl 103a wrapping around the ball head by adjusting the inner diameter size of the snap spring 103b, solving the problem of the reduced force of the ball bowl wrapping around the ball head at high temperatures.

[0033] In addition, the snap spring 103b is an annular metal product.

[0034] 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 at the position away from the adjustment base 101 is a four-petal structure.

[0035] It should be noted that the ball bowl 103a is divided into four petals, solving the problem of the ball bowl cracking when installing the ball head in the past, and solving the problem of baking the base to soften it before assembling the ball head in the past.

[0036] Furthermore, a connecting seat 101a is fixedly connected to the bottom of the adjustment base 101.

[0037] Furthermore, a first shaft rod 101b is fixedly connected to the top of the adjustment base 101.

[0038] Furthermore, a second shaft rod 102a is fixedly connected to the top of the adjustment knob 102, and the second shaft rod 102a is hinged to the connecting seat 101a.

[0039] During use, insert the ball head into the ball bowl 103a, and the snap spring 103b on the outside of the ball bowl 103a will cause the four-petal structure of the ball bowl 103a to tighten inward, solving the problem of the reduced force of the ball bowl wrapping around the ball head at high temperatures. Its structure is simple, the assembly is convenient, the product assembly efficiency is improved; it saves more product costs and has better practicability.

[0040] Embodiment 2

[0041] Refer to Figure 1 - Figure 5, based on the previous embodiment, this embodiment provides an integrated manual anti-glare adjustment structure with a snap spring. An inner side of the mirror housing 104 is provided with a first mounting groove 104a, and the first shaft rod 101b is rotatably connected to the first mounting groove 104a.

[0042] Furthermore, the inner side of the mirror housing 104 is provided with a second mounting groove 104b, the second shaft rod 102a is rotatably connected to the second mounting groove 104b, and the connecting shaft 105 is connected to the ball bowl 103a through a ball head.

[0043] It should be noted that both the first mounting groove 104a and the second mounting groove 104b are U-shaped grooves. The adjustment base 101 and the adjustment knob 102 are installed inside the mirror housing 104. The installation method is that the U-shaped grooves on the mirror housing 104, and the first shaft rod 101b and the second shaft rod 102a on both sides of the adjustment base 101 and the adjustment knob 102 are stuck inside the U-shaped grooves and cannot escape, but can rotate along the axis of the U-shaped grooves.

[0044] During use, as Figure 2 shown, when the adjustment knob 102 is toggled to one side, the adjustment knob 102 will rotate along the second shaft rod 102a to one side. At the same time, an opposite force will be generated at the position of the second shaft rod 102a. Since the adjustment knob 102 and the adjustment base 101 are integrated, the opposite force will act on the adjustment base 101, and the adjustment base 101 will rotate downward along the first shaft rod 101b. Since the lens is installed on the connecting shaft 105 and the connecting shaft 105 is fixed, when the adjustment base 101 rotates, the lens will also rotate by a certain angle. When the adjustment knob 102 rotates, the connecting shaft 105 will rotate by a certain angle. When the connecting shaft 105 is installed on the vehicle, the lens will rotate by an angle with the adjustment of the connecting shaft 105 by the adjustment knob 102, thereby changing the angle of the reflected light.

[0045] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible without materially departing from the novel teachings and advantages of the subject matter described in this application (e.g., changes in the dimensions, scales, structures, shapes and proportions of various elements, as well as parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, colors, orientations, etc.). For example, elements shown as integrally formed may be composed of multiple parts or elements, the positions of the elements may be inverted or otherwise changed, and the nature, number or position of discrete elements may be altered or changed. Therefore, all such modifications are intended to be included within the scope of the present utility model.
