The mode adopted in the prior art can realize the function of widening the visual field, but the connection between the additionally arranged external rearview mirror and the original external rearview mirror is unstable, and when a special vehicle works, the road surface of the working place of the special vehicle is not flat due to the vehicle type, so that the additionally arranged external rearview mirror is easy to fall off from the original rearview mirror in the driving process, the situation is unchanged for a driver, and new potential safety hazards caused by suddenly shrinking the visual field range are easy to cause. Furthermore, the added exterior mirror generally cannot be used for adjusting the field range at multiple angles by rotating the exterior mirror itself.
In addition, the actual width of the vehicle is very wide due to the additionally arranged outer rearview mirror, a driver can misjudge the actual width of the vehicle, the fixing device of the additionally arranged outer rearview mirror is complex in structure, and various fixing pieces enable the visual field of the driver to be shielded and are not attractive.
Therefore, it is necessary to modify the structure of the external rearview mirror of the special vehicle, and simultaneously ensure that the original external rearview mirror body and the mirror base body for installing the original external rearview mirror can be fully utilized as much as possible, so as to reduce the research and development risk, and simultaneously reduce the energy consumption and environmental pollution caused by full-system brand-new development, so that the product development is developed towards the direction of lower cost, energy conservation and environmental protection.

In the prior art, the mirror base body is directly connected with the mirror body in a rotating way, the purpose of the rotating connection is to enable the outer rearview mirror to be retracted and folded, and driving is convenient, however, aiming at the special vehicle in the background art, the length of the part, connected with the mirror body, of the mirror base body is shorter, so that the outer rearview mirror is closer to the vehicle body, the visual field range of the outer rearview mirror is closer to the vehicle body, and when the mirror base is applied to the special vehicle with the longer vehicle body, the vehicle body occupies a larger visual field range in the outer rearview mirror, so that the visual field range, which is outside the vehicle body and can display road conditions, is reduced.
In this embodiment, an extension structure is added between the lens base body and the lens body, one end of the extension structure is rotationally connected with the lens base body, so that the retraction and folding of the external rearview mirror can still be realized, the folding function of the original external rearview mirror is reserved, the other end of the extension structure is rotationally connected with the lens body, and due to the addition of the extension structure, the distance between the lens base body and the lens body can be increased, so that the visual field range of the external rearview mirror is changed, the relative positions of the lens body and the extension structure can be changed, the visual field adjusting range of the lens body can be further increased by the rearview mirror with the three-fold structure, the condition that the road condition of the external rearview mirror displays the visual field range is avoided to be smaller, and the driving safety degree is improved;
the lengthened structure and the mirror body are also in rotary connection, the relative positions of the mirror body and the lengthened structure can be changed, the rearview mirror with the three-fold structure can further increase the visual field adjusting range of the mirror body, the condition that the road condition of the external rearview mirror is displayed in a smaller visual field range is avoided, and the driving safety degree is improved;
the embodiment also adopts a rotating shaft mode to enable the lengthening structure to be rotationally connected with the lens seat body, so that the contact surface between the lengthening structure and the lens seat body is increased, the lens seat body can provide stronger supporting effect for the lengthening structure and the lens body, and the stability of the track of the lengthening structure during rotation can be increased; under the prerequisite that the mirror body has self weight, when the extension structure revolutes the pivot, can lead to the spare part impaired easily owing to the contact friction between extension structure and the pivot that the skew of atress led to, thereby lead to higher fault rate and maintenance rate, increase the elastic component in the rotation part, the both ends of elastic component can be simultaneously to the bottom of annular groove and the one side of clamp ring orientation elastic component applys elastic force, make the rotation part is when rotatory around the pivot, each position of elastic component takes place elastic compression deformation and is different to some extent to make the elastic component spontaneous balanced the unbalanced acting force between extension structure to the pivot, thereby make the rotation part evenly with the contact of pivot when rotatory, make the rotation of rotation part more steady, thereby the rotation of extension structure is also more steady.
The lengthening structure disclosed in this embodiment also has the following advantages in practical application: the lengthened structure disclosed in this embodiment is suitable for the mirror body part which is produced in mass production, and only needs to coordinate and adjust the mirror seat body part according to the structural requirement of the lengthened part, so that the lengthened structure disclosed in this embodiment has very high adaptability, can directly utilize the original mirror seat body and mirror body, reduces research and development and manufacturing risks, reduces product development cost, shortens development period, enhances product competitiveness, can also reduce product types, shortens manufacturing period, reduces manufacturing cost, reduces energy consumption and is more environment-friendly.
