Abstract

The utility model discloses a telescopic rear-view mirror of curved boom, its characterized in that: the bending device comprises a support, a bent arm and a lens, wherein the bent arm is movably arranged on the support, the lens is fixedly arranged on the bent arm, and the bent arm is arranged on the support in a sliding manner along an arc line; when the curved arm slides on the bracket, the lens keeps a fixed associated angle between the eyepoint and the view target point behind the vehicle. Has the advantages of simple structure and convenient adjustment.

Description

Bent arm telescopic rearview mirror

Technical Field

The utility model relates to an automobile parts field, concretely relates to automobile rearview mirror.

Background

The automobile outer rear-view mirror is one of the essential parts of the automobile, is fixedly arranged on two sides of the front part of the automobile body, is used for observing the conditions and barriers at the rear parts of the two sides of the automobile body, and plays an important role in the safety of automobile driving.

A conventional automobile rearview mirror generally includes a bracket, a shield, a mirror casing, a mirror ring, a mirror tray, and a diverter mounted on the mirror tray for adjusting the viewing angle of the mirror so as to obtain a suitable viewing angle range for observing the conditions of the rear parts of the two sides of the automobile body. In addition, a telescopic rearview mirror is also available on the market, and is now mostly used on heavy trucks. With the technical upgrade, the telescopic rearview mirror is also applied to automobiles, particularly electric automobiles. However, the conventional telescopic rearview mirror can be extended and retracted only in a straight line due to the relationship of the straight arms. When the lens is shifted from inside to outside as shown in fig. 1, the straight arm is extended and retracted, meaning that the lens also needs to be adjusted in order to get a proper field of view and vice versa.

In addition, how to improve the telescopic rearview mirror to overcome the above problems is a problem to be solved by those skilled in the art

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pair of simple structure can once adjust the telescopic rear-view mirror of the bent arm that targets in place.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a telescopic rear-view mirror of bent arm which characterized in that: the bending device comprises a support, a bent arm and a lens, wherein the bent arm is movably arranged on the support, the lens is fixedly arranged on the bent arm, and the bent arm is arranged on the support in a sliding manner along an arc line; when the curved arm slides on the bracket, the lens keeps a fixed associated angle between the eyepoint and the view target point behind the vehicle. It should be noted that the eyepoint is the position of the driver's eyes, and the visual field target point is the rear visual field that the driver needs to see.

Preferably, the curved arm slides along an arc line and is arranged on the support, and when the curved arm slides on the support, the lens moves by taking the eye point as a circle center.

Compared with the prior art, the utility model has the advantages of: when the bent arm moves on the support, the lens keeps a fixed associated angle between an eye point and a view target point behind a vehicle, namely an imaging position of the view target point on the lens is kept unchanged, so that the lens does not need to be adjusted. Make this scheme have simple structure, adjust convenient advantage.

Drawings

Fig. 1 is a schematic view of a conventional telescopic rearview mirror according to the present invention;

fig. 2 is a schematic diagram of the operation of a preferred embodiment of the present invention.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

In the description of the present invention, it should be noted that, for the orientation words, if there are terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the orientation and positional relationship indicated are based on the orientation or positional relationship shown in the drawings, and only for the convenience of describing the present invention and simplifying the description, it is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and not be construed as limiting the specific scope of the present invention.

As shown in fig. 1, the working principle of the existing linear telescopic rearview mirror is shown. As can be seen from fig. 1, when the lens is changed from inside to outside, the view target point B is translated on the lens, and an angle adjustment is required to be performed on the lens in order to obtain a proper view range. There is a great inconvenience.

For the present embodiment, a telescopic structure of the bending arm is adopted, as shown in fig. 2: this embodiment includes support 1, curved boom 2 and lens 3, and the activity of curved boom 2 sets up on support 1, and lens 3 is fixed to be set up on curved boom 2, and curved boom 2 slides along the circular arc line and sets up on support 1 for lens 3 uses the eyepoint to remove as the centre of a circle.

When the curved arm 2 slides on the bracket 1, the lens 3 keeps a fixed associated angle between the eye point a and the field target point B behind the vehicle, i.e. the imaging position of the field target point B on the lens 3 remains substantially unchanged. Therefore, after the bending arm 2 is extended, the lens is not required to be adjusted, and a proper visual field range can be obtained.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
