With the continuous development of the automobile industry, higher and higher requirements are put forward for the convenience of mounting, the stability of use and the cost control of the rearview mirror.

[0003] The existing rearview mirror rotating shaft is usually composed of a single rotating shaft, two gaskets and a spring, and these components need to be placed inside the lower mirror arm. The rotating shaft is limited in position by the internal structure of the support, and when the rearview mirror rotates, the rotating process is controlled by the gear disc. The gear disc rotates up and down due to the spring. This traditional structure gradually exposes some deficiencies and defects in long-term practical application.

[0004] On the one hand, during the assembly process, the rotating shaft structure is relatively complex and the matching precision of each component is high, which may cause differences during the assembly of the rotating shaft. Even under standardized production processes, the rotating characteristics of each product may still differ slightly, which not only affects production efficiency, but also may lead to unstable product quality. Once the assembly difference exceeds a certain range, the rearview mirror may have problems such as unsmooth rotation, looseness and abnormal noise during use, which brings poor user experience to the driver and also hides safety hazards.

[0005] On the other hand, from the cost point of view, the existing structure design is not optimized. In order to adapt to this traditional rotating shaft structure during the assembly process, the support also needs to be specially made with a complex structure to hold the rotating shaft, which further increases the difficulty and cost of production and manufacturing. In today's competitive automobile parts market, this undoubtedly weakens the competitiveness of the product.

[0031] The rotating shaft 2 penetrates the middle of the lower support 6, a ring groove 13 is arranged at the bottom in the lower support 6, and limiting insertion holes 16 are arranged in a ring shape on the top of the ring groove 13.

[0032] The bottom washer 8 is installed on the top of the ring groove 13, clamping holes 14 are arranged in a ring shape on the top of the bottom washer 8, and insertion columns 15 are arranged in a ring shape on the bottom of the bottom washer 8.

[0033] The insertion columns 15 on the bottom of the bottom washer 8 and the limiting insertion holes 16 on the top of the ring groove 13 are clamped with each other, the clamping blocks 11 on the bottom end of the rotating shaft 2 and the clamping holes 14 on the top of the bottom washer 8 are matched with each other.

[0034] The top of the bottom gasket 8 is sequentially installed with the connecting spring 4 and the limiting gasket 7, both of which are sleeved outside the rotating shaft 2 during installation, between the outer bevel edge 10 of the rotating shaft 2 and the clamping block 11.

[0035] In this structure, during assembly, the limiting gasket 7, the connecting spring 4, and the bottom gasket 8 are sequentially placed from the bottom of the lower support 6, wherein the bottom gasket 8 is placed vertically first, then turned back, so that the bottom of the bottom gasket 8 is clamped in the limiting insertion hole 16 on the ring groove 13, and then the rotating shaft 2 is inserted into the lower support 6. Specific embodiment two:

[0037] Reference Figures 1-5 , the automobile mirror installation more convenient rotating shaft structure, aims to optimize the installation process of automobile rearview mirror, improve the installation efficiency, at the same time ensures the stability and reliability in the use process. Main parts include mirror arm 1, lower support 6, limiting gasket 7, connecting spring 4 and bottom gasket 8, etc., each part cooperates with each other, realizes the unique function.

[0038] The whole installation steps are as follows:

[0039] (I) preparation stage

[0040] Before starting installation, make sure that all parts are complete and undamaged, including mirror arm 1, lower support 6, limiting gasket 7, connecting spring 4, bottom gasket 8, rotating shaft 2 and the structure of the accompanying protrusion 9, bevel edge 10, clamping block 11, etc. The characteristics such as meshing ring 18, meshing line 3, notch 17, bevel insertion slot 12, ring groove 13, limiting insertion hole 16, clamping hole 14 and insertion column 15 are clear and have no deformation.

[0041] (II) bottom gasket 8 installation

[0042] Pick up the bottom gasket 8, as described in embodiment one, first turn it vertically, so that the insertion column 15 at the bottom is aligned with the limiting insertion hole 16 at the top of the ring groove 13 in the lower support 6.

[0043] Slowly put the bottom gasket 8 into the bottom of the lower support 6, press gently, make sure that the insertion column 15 is accurately clamped into the limiting insertion hole 16, at this time the bottom gasket 8 is preliminarily fixed on the ring groove 13, and the first step of installing the bottom gasket 8 is completed.

[0044] (III) connecting spring 4 and limiting gasket 7 installation

[0045] Take the connecting spring 4, align one end of it with the center hole position of the bottom gasket 8 which has been installed, then along the direction of the rotating shaft 2, sleeve the connecting spring 4 outside the rotating shaft 2, so that it is located between the outer bevel edge 10 of the rotating shaft 2 and the clamping block 11 at the predetermined position.

[0046] Pick up the limiting gasket 7, also sleeve joint in the outer part of the rotating shaft 2, make it above the connecting spring 4, and close to the connecting spring 4, ensure that the two are installed stably on the rotating shaft 2, and will not shake at will.

[0047] (Four) rotating shaft 2 and mirror arm 1 combination installation

[0048] After the installation of the above-mentioned components at the bottom of the lower support 6 is completed, pick up the mirror arm 1 with the structure of the engaging ring 18 and the rotating shaft 2, etc.

[0049] The bottom end of the rotating shaft 2 is aligned with the middle hole of the lower support 6, and the rotating shaft 2 penetrates the lower support 6. During this process, the following points need to be noted:

[0050] The protrusions 9 on both sides of the outer top of the rotating shaft 2 are aligned with the notches 17 opened in the front and back of the lower support 6, and are slowly inserted until the protrusions 9 are completely embedded in the notches 17, realizing the preliminary limiting of the mirror arm 1 in the horizontal direction, preventing it from rotating at will.

[0051] At the same time, the bevel edges 10 on the outside of the rotating shaft 2 are inserted into the bevel slots 12 on both sides of the top of the lower support 6. Since the bevel edges 10 and the bevel slots 12 are both triangular and match each other, a slight angle adjustment may be needed during insertion to ensure tight insertion. This step provides stable support for the mirror arm 1 in the vertical direction, and then the riveting operation is performed.

[0052] (Five) final adjustment and fixation

[0053] When the rotating shaft 2 is completely inserted into the lower support 6, the clamping block 11 on the bottom end of the rotating shaft 2 will match the clamping hole 14 on the top of the bottom gasket 8. At this time, gently rotate the mirror arm 1 to check whether it rotates smoothly or not.

[0054] If it rotates smoothly, it means that all parts are installed in place; if there is a problem, you need to carefully check the connection parts to see if there are parts not installed correctly, such as the protrusions 9 not completely embedded in the notches 17, the bevel edges 10 and the bevel slots 12 not tightly inserted, etc. Adjust in time until the mirror arm 1 rotates freely.

[0055] When the angle of the automobile rearview mirror needs to be adjusted, the driver manually applies external force to the mirror arm 1 to make it rotate around the rotating shaft 2. Since the rotating shaft 2 and the lower support 6 are limited in multiple directions through the cooperation of the protrusions 9 and the notches 17, and the bevel edges 10 and the bevel slots 12, the mirror arm 1 maintains a certain stability during rotation, and can also adjust the angle flexibly.

[0056] The connecting spring 4 plays a buffering role during the rotation of the mirror arm 1, avoiding rigid collision between the mirror arm 1 and the lower support 6 due to excessive external force, protecting the structure of each part, and also providing a certain resilience to the mirror arm 1, so that it can maintain a relatively stable position after adjustment.

[0057] (II) Limiting and fixing function

[0058] The limiting washer 7 cooperates with the connecting spring 4 to further limit the rotation range of the mirror arm 1, prevent it from rotating excessively beyond the normal use angle, and avoid damaging the rearview mirror or affecting the observation line of sight.

[0059] The bottom washer 8 not only cooperates with the clamping block 11 at the bottom end of the rotating shaft 2 through the bayonet 14 to fix the axial position of the rotating shaft 2, but also connects with the limiting socket 16 of the ring groove 13 through the bottom insertion column 15, thereby enhancing the bottom stability of the entire structure, ensuring that the rearview mirror rotating shaft structure is still firm and reliable in the bumpy and vibrating environment during vehicle driving, and ensuring that the rearview mirror is always in a normal working state.

[0060] In summary:

[0061] 1. In the device, when the angle of the automobile rearview mirror needs to be adjusted, the driver manually applies an external force to the mirror arm 1 to make it rotate around the rotating shaft 2. Due to the cooperation of the convex block 9 and the notch 17, as well as the cooperation of the beveled edge 10 and the beveled slot 12 between the rotating shaft 2 and the lower support 6, the mirror arm 1 can be stably rotated and flexibly adjusted in angle.

[0062] The connecting spring 4 plays a buffering role during the rotation of the mirror arm 1, avoiding rigid collision between the mirror arm 1 and the lower support 6 due to excessive external force, protecting the structure of each component, and also providing a certain rebound force for the mirror arm 1, so that it can maintain a relatively stable position after adjustment.

[0063] 2. The limiting washer 7 cooperates with the connecting spring 4 to further limit the rotation range of the mirror arm 1, prevent it from rotating excessively beyond the normal use angle, and avoid damaging the rearview mirror or affecting the observation line of sight.

[0064] The bottom washer 8 not only cooperates with the clamping block 11 at the bottom end of the rotating shaft 2 through the bayonet 14 to fix the axial position of the rotating shaft 2, but also connects with the limiting socket 16 of the ring groove 13 through the bottom insertion column 15, thereby enhancing the bottom stability of the entire structure, ensuring that the rearview mirror rotating shaft structure is still firm and reliable in the bumpy and vibrating environment during vehicle driving, and ensuring that the rearview mirror is always in a normal working state.
