Description

Technical Field

[0001] The utility model relates to the field of automobile manufacturing, in particular to a novel gooseneck type hidden electronic rearview mirror structure. Background Art

[0002] Electronic exterior rearview mirrors with cameras installed on the outside and display screens on the inside are smaller than traditional optical rearview mirrors, can reduce wind resistance and blind spots, and can cope with harsh operating environments such as rain and snow. More and more automobile manufacturers are replacing traditional optical rearview mirrors with electronic exterior rearview mirrors. However, such electronic exterior rearview mirrors are weak in strength, easy to damage, and have high maintenance costs. They are easy to cause harm to pedestrians and are easy to be stolen. At the same time, the rearview mirrors in the existing technology cannot be completely retracted into the body sheet metal, which increases the risk of the camera being scratched.

[0003] In the prior art, some exterior rearview mirrors can be retracted into the structure inside the vehicle body sheet metal, and usually the exterior rearview mirrors are directly rotated. However, for storage purposes, the rotation axis must be located inside the vehicle body sheet metal. Therefore, when rotating the mirrors, the mirrors usually cannot be completely rotated to the outside of the vehicle body sheet metal, affecting the field of view of the mirrors.

[0046] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0047] like Figure 1-6 As shown, this embodiment discloses a novel gooseneck hidden electronic rearview mirror structure.

[0048] Specific reference Figure 1 As shown, including

[0049] The exterior rearview mirror 100 comprises at least a base 110 and a camera assembly 120; the camera assembly 120 is mounted at the end of the first end of the base 110 and is used to collect images;

[0050] The body sheet metal 200 is provided with a cavity for accommodating the exterior rearview mirror 100; the opening of the cavity is arranged on the outer surface of the body sheet metal 200, and the mirror surface 111 on the exterior rearview mirror 100 is adapted to the opening;

[0051] The exterior rearview mirror can be moved between a hidden position and an extended position, wherein the mirror surface is hidden in the opening in the hidden position and the mirror surface is located outside the opening in the extended position;

[0052] A driving mechanism 300, the driving mechanism 300 drives the base 110 to move so that the camera assembly 120 extends out of the cavity or is hidden in the cavity;

[0053] A gooseneck arm 400 is disposed at the second end of the base 110, and the driving mechanism is connected to the gooseneck arm to drive the gooseneck arm to rotate, thereby rotating the exterior rearview mirror out of the cavity;

[0054] When the exterior rearview mirror 100 is extended, the mirror surface 111 is moved out of the cavity as a whole under the action of the gooseneck arm 400 , and has an arc-shaped moving trajectory.

[0055] The above is the basic solution of this embodiment.

[0056] Reference Figure 3 As shown, when the vehicle starts, the driving mechanism 300 starts, driving the first end of the gooseneck arm 400 to rotate, and the second end of the gooseneck arm 400 rotates around the first axis a, driving the base 110 to rotate and rotate out of the cavity, so that the camera assembly 120 is exposed outside the cavity, and the environment outside the vehicle can be filmed;

[0057] When the vehicle is turned off, the driving mechanism 300 is started again, and the gooseneck arm 400 rotates, driving the base 110 to rotate back into the cavity, thereby completing the hiding of the exterior rearview mirror 100 .

[0058] In this embodiment, when the exterior rearview mirror 100 is located at the hidden position, the mirror surface 111 does not protrude from the outer surface of the vehicle body sheet metal 200 .

[0059] Based on the above arrangement, when the vehicle is in motion, the camera assembly 120 is exposed, and when not needed, the exterior rearview mirror 100 together with the camera is hidden in the vehicle body sheet metal 200, which is beneficial for the vehicle to pass through narrow intersections; at the same time, when the vehicle is parked, debris is prevented from being deposited on the camera assembly 120, ensuring that the camera assembly 120 can obtain accurate field of view information when in use, thereby improving the aesthetic appearance of the vehicle.

[0060] Compared with other rotation methods, the special structure of the gooseneck arm 400 is utilized in this embodiment to enable the mirror 111 to be completely rotated out of the cavity, thereby maximizing the field of view of the mirror 111 .

[0061] Preferably, the first end of the gooseneck arm 400 is hinged to the driving mechanism 300, and the second end is fixed to the base 110; the first end of the gooseneck arm 400 is limitedly rotated under the action of the driving mechanism 300, driving the exterior rearview mirror 100 to rotate around the first axis a, see Figure 2 shown.

[0062] Preferably, in this embodiment, the rotation angle of the driving mechanism 300 can be limited, thereby limiting the rotation of the gooseneck arm 400, and a limit card point can also be provided on the gooseneck arm 400.

[0063] Preferably, in this embodiment, the opening angle of the exterior rearview mirror 100 is 35 degrees, and the unfolding angle is 140 mm from the vehicle body sheet metal. By adopting a gooseneck arm 400 in the shape of a gooseneck arm, the gooseneck arm 400 and the exterior rearview mirror 100 can maximize the mirror field of view when they are rotated at a small angle.

[0064] The specific implementation of the gooseneck arm 400 in this embodiment is as follows: the gooseneck arm 400 at least includes a long arm section 410 and a short arm section 420 that are bent and connected, the second end is located at the end of the long arm section 410, the first end is located at the end of the short arm section 420, and is hinged to the driving mechanism 300 through an axle pin 600;

[0065] The first axis a is the central axis of the shaft pin.

[0066] Reference Figure 2 As shown, in this embodiment, when rotating, the base 110 rotates around the first axis a, that is, revolves around the axis pin, so that the base 110 can be completely rotated out of the cavity and will not collide with the opening edge of the cavity during the rotation process.

[0067] Specifically, the long arm section 410 and the short arm end are both arc sections, and the curvature of the long arm section 410 is greater than that of the short arm section 420 .

[0068] Based on the above arrangement, when the driving component drives the gooseneck arm 400 to rotate, the rotating shaft is located at the end of the short arm section 420, driving the short arm section 420 to rotate in a small range, and the short arm section 420 can drive the long arm section 410 to rotate in a larger range. Therefore, the purpose of rotating the base 110 out of the cavity at a faster speed can be achieved. At the same time, the short arm section 420 has a small range of movement in the vehicle, thereby reducing the occupied space.

[0069] When the exterior rearview mirror is extended, the deformation stress on the outside is greater than that on the inside. The greater the angle of rotation, the greater the deformation stress, and thus the greater the load on the gooseneck arm.

[0070] Compared with the use of ordinary hinges to connect the exterior rearview mirror 100, in this configuration, the load of the exterior rearview mirror 100 on the gooseneck arm 400 in the extended state is within the material yield strength range of the gooseneck arm 400, thereby ensuring the structural stability of the gooseneck arm 400; if the rotation angle is too large, the stress result at the stress concentration point of the exterior rearview mirror 100 exceeds the material yield strength, which will cause irreversible plastic deformation of the exterior rearview mirror 100 or the gooseneck arm 400, i.e., product failure.

[0071] Preferably, in this embodiment, a receiving box 700 is provided in the vehicle body sheet metal 200, and the cavity is located in the receiving box 700;

[0072] The driving mechanism 300 is located outside the containing box 700 , and the axle pin 600 extends into the containing box 700 and is connected to the first end of the gooseneck arm 400 .

[0073] At the same time, refer to Figure 5As shown, in order to ensure the movement path of the gooseneck arm 400, a cover plate 500 is also included. An assembly gap is provided on the outer side of the gooseneck arm 400 on the accommodating box 700, and the cover plate 500 is used to fill this gap; an arc-shaped limiting groove is provided on the cover plate 500 facing the gooseneck arm 400, and the shape of the limiting groove is consistent with the movement track of the gooseneck arm 400.

[0074] Preferably, in this embodiment, the shape of the limit groove is based on the movement path of the bending point between the long arm section 410 and the short arm section 420 on the gooseneck arm 400. When the gooseneck arm 400 is turning out, the path of the bending point is an arc of maximum radius. Therefore, the movement path of this position is limited to ensure that the movement path of the entire gooseneck arm 400 is within the set range.

[0075] The side surface of the base 110 at least includes a camera surface 112 and a mirror surface 111 and an inner blocking surface located on both sides of the camera surface 112, and the extended surfaces of the mirror surface 111 and the inner blocking surface intersect at the side away from the camera;

[0076] The camera surface 112 is provided with a camera hole 112.1, and the recording end of the camera assembly 120 is exposed in the camera hole 112.1.

[0077] Preferably, in this embodiment, the horizontal cross section of the base 110 is a fan-shaped cross section, and the motion path of any point on the cross section is an arc.

[0078] Preferably, the imaging surface 112 is an outwardly convex arc surface, and the arc surface is consistent with the moving trajectory of the imaging surface 112 .

[0079] The imaging surface 112 is provided with an arc-shaped surface, and the recording end of the camera assembly 120 is provided at the outermost vertex of the arc-shaped surface, so as to ensure that the field of view will not interfere with the imaging surface 112, so as to maximize the field of view.

[0080] In this embodiment, in order to ensure that the camera assembly 120 does not contact the inner wall of the cavity and cause scratches when hidden, the position of the camera end is usually not protruding from the camera surface 112;

[0081] In other embodiments, to ensure the field of view, the camera end may be positioned slightly protruding from the camera surface 112. At the same time, a gap is left between the inner wall of the cavity on one side of the camera end and the camera surface 112 to ensure the safety of the camera end.

[0082] Reference Figure 4 As shown, the mirror surface 111 is a plane and is adapted to the opening of the cavity; when the base 110 is hidden in the cavity, the mirror surface 111 is flush with the vehicle body sheet metal 200 to form a whole.

[0083] Based on the above arrangement, when the exterior rearview mirror 100 is in the hidden state, the mirror surface 111 is flush with the vehicle body sheet metal 200, so that the vehicle body sheet metal 200 has a relatively flat appearance, thereby improving the aesthetic appearance of the vehicle; at the same time, the mirror surface 111 is arranged to be a straight structure, which plays a guiding role when unfolded and reduces air resistance.

[0084] In this embodiment, the specific connection method of the gooseneck arm 400 and the exterior rearview mirror 100 is as follows: Figure 6 As shown, a connecting section 430 is bent at the end of the long arm section 410, and the connecting section 430 is plugged into the base 110;

[0085] A slot 113 adapted to the connecting section 430 is disposed on the second end of the base 110 .

[0086] During assembly, the connection between the base 110 and the gooseneck arm 400 can be completed by simply inserting the connecting section 430 into the slot 113 .

[0087] Preferably, to ensure smooth plugging, the connecting section 430 is a straight section.

[0088] At the same time, in order to ensure the stable insertion of the connecting section 430 and the slot 113, the inner wall of the slot 113 is provided with a protruding positioning point, and the connecting section 430 is provided with a positioning groove 431 that cooperates with the positioning point.

[0089] When the connecting section 430 is inserted into the slot 113 , the positioning point is squeezed and deformed by the inner wall of the connecting section 430 until the connecting section 430 is inserted into place. The positioning groove 431 slides into the position of the positioning point along with the connecting section 430 , and the positioning point is inserted into the positioning groove 431 .

[0090] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
