[0001] This utility model relates to the field of vehicle technology, specifically to a rearview mirror assembly and a vehicle. Background Technology

[0002] In related technologies, the rearview mirrors of two-wheeled electric bicycles and electric motorcycles are only fastened to the brake handle of the vehicle body with nuts. This fastening method can cause the rearview mirror to loosen after being hit by external force, and tools are needed to re-tighten the rearview mirror. If the rider does not have the tools on the vehicle, the rearview mirror cannot be fastened in place, which causes inconvenience to riding and poses a safety hazard. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a rearview mirror assembly that addresses the defects and deficiencies of the prior art. After the head of the mirror rod of the rearview mirror assembly is assembled into the inner hole of the adapter section, the angle can be freely adjusted by the setting of the first notch. When the fastening nut is tightened in conjunction with the external thread of the adapter section, it can press the adapter section inward to close the first notch, thereby better clamping the mirror rod. At the same time, since the peripheral wall of the inner hole is provided with a threaded hole, the limiting bolt passing through the threaded hole can press against the mirror rod from the side, further improving the fastening effect of the mirror rod, thereby greatly improving the anti-rotation and anti-shaking ability of the mirror rod under external impact.

[0004] The rearview mirror assembly of this utility model embodiment includes: an adapter bolt, the adapter bolt including a fixed section and an adapter section, one end of the fixed section being connected to a brake handle, the adapter section being connected to the other end of the fixed section and having an inner hole and an external thread, and the peripheral wall of the inner hole having a first notch extending axially along the adapter bolt, and the peripheral wall of the inner hole having a threaded hole penetrating along its thickness direction, the threaded hole and the first notch being spaced apart circumferentially in the inner hole; a mirror rod assembly, a fastening nut and a limiting bolt, the mirror rod assembly including a mirror rod and a rearview mirror mounted on the tail of the mirror rod, the head of the mirror rod fitting in the inner hole, the fastening nut being sleeved on the head of the mirror rod and threadedly connected to the external thread of the adapter section, and the limiting bolt passing through the threaded hole and abutting against the mirror rod.

[0005] In this embodiment of the rearview mirror assembly, the head of the mirror rod can be freely adjusted in angle by utilizing the first notch after being assembled into the inner hole of the adapter section. When the fastening nut is tightened in conjunction with the external thread of the adapter section, it can press the adapter section inward to close the first notch, thereby better clamping the mirror rod. At the same time, since a threaded hole is provided on the peripheral wall of the inner hole, the limiting bolt passing through the threaded hole can press against the mirror rod from the side, further improving the fastening effect of the mirror rod, thereby greatly enhancing the mirror rod's anti-rotation and anti-shaking ability under external impact.

[0006] In some embodiments, the transition section includes a threaded connection section and an intermediate transition section, the intermediate transition section being located between the fixed section and the threaded connection section, the threaded connection section having the external thread and the first notch, and the intermediate transition section having the threaded hole.

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figures 1-5 As shown, the rearview mirror assembly of this utility model embodiment includes an adapter bolt 1, a mirror rod assembly, a fixing nut, and a limiting bolt 3.

[0026] Specifically, such as Figures 1-3 As shown, the adapter bolt 1 includes a fixed section 11 and an adapter section 12. One end of the fixed section 11 is connected to the brake handle 6. The adapter section 12 is connected to the other end of the fixed section 11 and has an inner hole and an external thread. The peripheral wall of the inner hole has a first notch 8 extending axially along the adapter bolt 1, and the peripheral wall of the inner hole is provided with a threaded hole that penetrates along its thickness direction. The threaded hole and the first notch 8 are spaced apart in the circumferential direction of the inner hole. The mirror rod assembly includes a mirror rod 4 and a rearview mirror 5 mounted on the tail of the mirror rod 4. The head of the mirror rod 4 fits in the inner hole. The fastening nut 2 is sleeved on the head of the mirror rod 4 and threadedly connected to the external thread of the adapter section 12. The limiting bolt 3 passes through the threaded hole and abuts against the mirror rod 4.

[0027] Understandably, before assembling the lens rod 4, the fastening nut 2 is first fitted onto the head of the lens rod 4, and then the head of the lens rod 4 is inserted into the inner hole. Due to the presence of the first notch 8, there is a margin in the inner hole to facilitate the adjustment of the lens rod 4 angle. After the angle adjustment is completed, the fastening nut 2 is tightened. As the fastening nut 2 is fixed, the connecting section with the notch will shrink inward and clamp the lens rod 4. After the fastening nut 2 is tightened to the correct position, the limiting bolt 3 is passed through the threaded hole and pressed against the lens rod 4.

[0028] Understandably, the notch design on the inner hole can provide a greater clamping force when the fastening nut 2 is tightened, thereby better clamping the lens rod 4. At the same time, the setting of the limiting bolt 3 can provide a clamping force to the lens rod 4 from the side. The combination of the two can greatly improve the fixing effect of the lens rod 4, thereby improving its ability to prevent rotation and shaking when subjected to external impact.

[0029] In this embodiment of the rearview mirror assembly, the head of the mirror rod 4 is fitted into the inner hole of the adapter section 12, and the angle can be freely adjusted by the setting of the first notch 8. When the fastening nut 2 is tightened in conjunction with the external thread of the adapter section 12, it can press the adapter section 12 inward to close the first notch 8, thereby better clamping the mirror rod 4. At the same time, since the peripheral wall of the inner hole is provided with a threaded hole, the limiting bolt 3 passing through the threaded hole can press against the mirror rod 4 from the side, further improving the fastening effect of the mirror rod 4, thereby greatly improving the anti-rotation and anti-shaking ability of the mirror rod 4 under external impact.

[0030] In some embodiments, the transition section 12 includes a threaded connection section and an intermediate transition section 13. The intermediate transition section 13 is located between the fixed section 11 and the threaded connection section. The threaded connection section has external threads and a first notch 8, and the intermediate transition section 13 has a threaded hole. In other words, the threaded hole is located at the lower end of the transition section 12, and no external threads are provided at the position of the threaded hole, so that the limiting bolt 3 can provide a better clamping effect.

[0031] For example, if the location of the threaded hole also has an external thread, the clamping surface of the limit bolt 3 will contact the external thread after tightening. During long-term use, the clamping may become loose due to deformation or wear of the external thread.

[0032] In some embodiments, such as Figure 3 As shown, the intermediate transition section 13 protrudes outward radially from the threaded connection section and the fixing section 11 relative to the adapter bolt 1. Therefore, the intermediate transition section 13 is relatively thicker, which can improve the structural strength of the entire adapter bolt 1 and provide better load-bearing capacity for the limit bolt 3, avoiding the risk of deformation due to the large preload of the limit bolt 3.

[0033] In some embodiments, the first notches 8 are a plurality of those arranged at circumferential intervals along the inner hole. It is understood that the more first notches 8 there are, the greater the aperture adjustment margin they can provide, and the easier it is to adjust the angle of the mirror rod 4.

[0034] Preferably, there are two first notches 8, which are arranged opposite each other in the radial direction of the inner hole.

[0035] In some embodiments, a groove 7 is provided on the outer peripheral surface of the head of the mirror rod 4, and the end of the limiting bolt 3 abuts directly into the groove 7. For example... Figure 1 As shown, the surface of the traditional mirror rod 4 is mostly curved, and the limiting bolt 3 is prone to slippage when it comes into contact with the curved surface. By setting the groove 7, the end of the limiting bolt 3 can be inserted into the recessed position, thereby solving the problem of slippage of the pressing surface and improving the reliability of the limiting.

[0036] In some embodiments, the outer end of the limiting bolt 3 is provided with an auxiliary handle or tool slot. Thus, when assembling the limiting bolt 3, an external tool can be connected to the tool slot or the auxiliary handle can be used to manually tighten it, improving the ease of operation.

[0037] Furthermore, such as Figure 2 As shown, the screw hole of the fastening nut 2 includes a first hole section and a second hole section. The first hole section is located on an internal thread that mates with the external thread. The second hole section is located on the side of the first hole section away from the fixed section 11, and the diameter of the second hole section is smaller than the diameter of the first hole section. In other words, there is a radial dimensional difference between the first hole section and the second hole section, resulting in a stepped surface between them. This stepped surface can be used for assembly and positioning by abutting against the end of the transition section 12 when the fastening nut 2 is tightened.

[0038] In some embodiments, the rearview mirror assembly further includes a damping sleeve 9, which is fitted onto the head of the mirror rod 4. Thus, when the mirror rod assembly is subjected to an external impact, the damping sleeve 9 can absorb a certain amount of energy, providing a damping and anti-rotation effect. When it is necessary to adjust the angle of the rearview mirror 5, external force can be directly applied to the mirror rod assembly to adjust the angle to any desired level without the need for external tools. Furthermore, it is not affected by wind resistance or bumps during riding, preventing the mirror rod 4 from shifting or loosening, thus eliminating safety hazards.

[0039] Furthermore, such as Figure 5 As shown, the damping sleeve 9 has a second notch 10 extending along its axial direction. Thus, the second notch 10 facilitates the fitting of the damping sleeve 9 with the mirror rod 4, and also provides a greater tightening force when the fastening nut 2 tightens the adapter section 12, better fitting the mirror rod 4 and improving the damping effect.

[0040] Furthermore, such as Figure 4 and Figure 5As shown, the damping sleeve 9 includes a cylindrical body 91 and an outer flange 92. The cylindrical body 91 is sleeved on the head of the mirror rod 4. The outer flange 92 is connected to the end of the cylindrical body 91 away from the fixed section 11 and extends outward along the radial direction of the cylindrical body. The connecting surface between the first hole section and the second hole section is a pressing surface. The flange is clamped between the end face of the transition section 12 and the pressing surface.

[0041] Therefore, when the fastening nut 2 and the transition section 12 are tightened, the outer flange 92 can be pressed down, thereby preventing the damping sleeve 9 from rotating and ensuring its damping anti-rotation reliability.

[0042] The vehicle of this utility model embodiment includes the rearview mirror assembly described in the above embodiment.

[0043] In the vehicle of this utility model embodiment, by adopting the above-mentioned rearview mirror assembly, the head of the mirror rod 4 can be freely adjusted by using the first notch 8 after being assembled into the inner hole of the adapter section 12. When the fastening nut 2 is tightened in conjunction with the external thread of the adapter section 12, it can press the adapter section 12 inward to close the first notch 8, thereby better clamping the mirror rod 4. At the same time, since the threaded hole is provided on the peripheral wall of the inner hole, the limiting bolt 3 passing through the threaded hole can press against the mirror rod 4 from the side, further improving the fastening effect of the mirror rod 4, thereby greatly improving the anti-rotation and anti-shaking ability of the mirror rod 4 under external impact, resulting in good vehicle performance.
