[0034] In the design of light commercial vehicles, every detail of the door structure is related to the overall performance of the vehicle and the comfort of the passengers. When the door is closed, the rearview mirror, as an important part of the vehicle, not only undertakes the task of observing the road conditions, but also directly affects the driving experience and safety. The part of the rearview mirror arm connected to the vehicle body can be regarded as a cantilever beam structure in mechanics. This structure is prone to vibration when subjected to external force (such as impact force when the door is closed), which not only affects the clarity of the rearview mirror, but also may cause parts to loosen or damage due to long-term vibration. The existing rearview mirror design often does not fully consider this structural feature, especially at the moment when the door is closed, the impact force is large and concentrated, and the vibration phenomenon is obvious.

[0035] Therefore, the utility model provides a kind of vehicle mirror arm, to optimize the structure of mirror arm, solve the problem of commercial vehicle rearview mirror arm vibration to some extent, also take into account the demand of light weight and structural strength.

[0036] Please refer to Figures 1 to 3 In an embodiment of the present application, the vehicle mirror arm includes a mirror rod segment 100 for installing a mirror and two connecting rod segments 200 connected to the two ends of the mirror rod segment 100 respectively, the mirror rod segment 100 is hollow, and the connecting rod segment 200 is used to connect with the vehicle body; the wall thickness of the connecting rod segment 200 is greater than the wall thickness of the mirror rod segment 100.

[0037] In another embodiment, the vehicle mirror arm includes a mirror rod segment 100 for installing a mirror and two connecting rod segments 200 connected to the two ends of the mirror rod segment 100 respectively and a diagonal support, the connecting rod segment 200 is used to connect with the vehicle body; one end of the diagonal support is connected to the connecting rod segment 200, and the other end is used to connect with the vehicle body.

[0038] The technical scheme of the utility model discloses a hollow structure of the mirror rod section 100, which reduces the overall weight and increases the flexibility of the mirror arm to a certain extent, so that the mirror can better absorb and disperse the impact when subjected to external force, and reduce the vibration; compared with the mirror rod section 100, in one scheme, the wall thickness of the connecting rod section 200 is deliberately thickened. This design significantly enhances the rigidity of the connection between the mirror arm and the vehicle body, making the entire structure more stable when facing the door closing impact force, effectively suppressing the occurrence of vibration phenomenon. In another scheme, one end of the inclined support is connected to the connecting rod section 200, and the other end is connected to the vehicle body, forming a triangular or triangular-like stable structure. The inclined support not only provides additional support force, but also absorbs and disperses vibration energy through its elastic deformation, further reducing the vibration phenomenon of the mirror arm during door closing or driving, improving the clarity and service life of the rearview mirror.

[0039] Please refer to Figures 1 to 3 In the scheme where the wall thickness of the connecting rod section 200 is greater than that of the mirror rod section 100, further, the connecting rod section 200 is hollow, and the wall thickness of the connecting rod section 200 gradually increases from the mirror rod section 100 to the connecting rod section 200. In this way, the lightweight of the connecting rod section 200 can be maintained, and additional strength and stability can be provided at the key parts connected to the vehicle body, further reducing the vibration phenomenon of the mirror arm during door closing or driving. Since the connecting rod section 200 has a thicker wall thickness at the part connected to the vehicle body, these parts can better withstand the force and vibration from the vehicle body, thereby enhancing the reliability of the connection.

[0040] In one embodiment, the gradually increasing wall thickness of the connecting rod section 200 is formed by hot extrusion. The connecting rod section 200 is placed in a hot extrusion die, and through heating and pressure, the material is plastically deformed in the die, thereby achieving a gradually increasing wall thickness.

[0041] In one embodiment, the connecting rod section 200 is stretched or compressed by a mechanical device, and by adjusting the speed and force of stretching or compression, the material is plastically deformed in the local area, thereby achieving a gradually increasing wall thickness.

[0042] In one embodiment, the outer diameter of the mirror rod section 100 and the connecting rod section 200 is the same. In this way, the connecting rod section 200 can be connected to the original mirror arm connection seat of the door, without the need to replace parts such as accessories. Of course, in other embodiments, the size of the mirror arm connection seat can be changed for ease of manufacturing.

[0043] Please refer to Figure 2 and Figure 3Specifically, the wall thickness of the connecting rod section 200 has a maximum value D, and the wall thickness of the mirror rod section 100 has a value d, and D / d>2. The thicker connecting rod section 200 (with a larger D value) can provide a larger contact area and stronger connection strength when connected to the vehicle body, effectively resisting various forces and vibrations from the vehicle body.

[0044] Specifically, the wall thickness of the connecting rod section 200 ranges from 2mm to 6mm.

[0045] In a typical light commercial vehicle, the wall thickness of the mirror rod section 100 is 2mm. In an embodiment of the present solution, the maximum wall thickness D of the connecting rod section 200 is 4.5mm. In other embodiments, the wall thickness of the connecting rod section 200 needs to be considered in combination with various factors and reasonably balanced and optimized.

[0046] Specifically, the connecting rod section 200 and the mirror rod section 100 are gradually transitioned, and the inner diameter of the connecting rod section 200 has a maximum value that is less than or equal to the inner diameter of the mirror rod section 100, i.e., the minimum wall thickness of the connecting rod section 200 is greater than or equal to the wall thickness of the mirror rod section 100. In an embodiment of the present solution, the two are equal at the connection, which is 2mm.

[0047] Please refer to Figure 1 Specifically, the length of the mirror rod section 100 is L, and the length of the connecting rod section 200 is l, and 1 / 4≤l / L<1 / 3. The connection between the mirror rod section 100 and the connecting rod section 200 has a curved transition portion, and the distance between the two transition portions can be taken as the length of the mirror rod section 100. Within this proportion range, the connecting rod section 200 is relatively short, and the mirror rod section 100 is relatively long. Such a design allows the connecting rod section 200 to be more compactly connected to the vehicle body, providing stable support. The shorter connecting rod section 200 means that the stress is more concentrated when subjected to external forces, but due to the gradually increasing wall thickness design, the connecting rod section 200 can resist greater forces and vibrations, ensuring the stability of the rearview mirror.

[0048] Specifically, for the convenience of manufacturing, the connecting rod section 200 and the mirror rod section 100 are welded together.

[0049] In an embodiment, the material of the connecting rod section 200 and the material of the mirror rod section 100 are the same.

[0050] In another embodiment, the connecting rod section 200 and the mirror rod section 100 are different metal materials in terms of grade. Here, different metal materials in terms of grade refer to materials of similar chemical composition but different grades, such as 304 stainless steel and 316 stainless steel, etc.

[0051] In an embodiment, the connecting rod section 200 and the mirror rod section 100 are both circular tubes, and the mirror rod section 100 is provided with a mounting portion 110 for connecting a mirror. The mounting portion 110 is provided as a circular hole and extends along the axial direction of the mirror rod section 100. The mirror is mounted on the mounting portion 110.
