Technical Field

The present invention relates to a vehicle rearview mirror.

Background

In the prior art, rear view mirrors for automobiles or motorcycles are known. The known rear-view mirror comprises an arm for attachment to the vehicle, a casing rotatably mounted to the attachment arm, a mirror rotatably mounted to the casing, a first motor fixedly mounted to the attachment arm, which motor allows the casing to rotate about a vertical geometric rotation axis, so as to switch the rear-view mirror casing from an operating position to a flip position in which it is folded towards the frame of the motor vehicle so as to occupy a smaller overall size, and a second motor fixedly mounted to the casing, allowing the mirror to rotate about two geometric rotation axes to adjust the rear-view field of the driver of the motor vehicle. The mirror is rotatably mounted on a housing which is rotatably mounted on an arm of the vehicle mirror.

Disadvantageously, known rearview mirrors have a relatively large overall bulk size due to the need to ensure that the mirror is large enough to meet the full field of view required by traffic regulations.

Disadvantageously, the considerable overall dimensions of the rear-view mirror negatively affect the aerodynamic shape of the motor vehicle, reducing its performance and consuming more fuel.

Disadvantageously, the rotation mechanism of the mirror on both axes is exposed to impacts and tampering, making the rear view mirror fragile.

Disclosure of Invention

The object of the present invention is to provide a more compact, safe, robust, more protected, less fragile rear view mirror, which allows the driver of the motor vehicle to see a complete field of view, which allows the motor vehicle to possess better aerodynamic characteristics, thus allowing lower fuel consumption or better vehicle performance, solving the drawbacks of the prior art.

According to the invention, this object is achieved by a rear view mirror for a vehicle according to claim 1.

Other features are envisaged in the dependent claims.

Detailed Description

Referring to the preceding figures, there is shown a vehicle rearview device 10 including a support arm 20 adapted to be fixedly mounted on the vehicle, a housing 30 rotatably mounted on the support arm 20, and a mirror 40 fixedly mounted on the housing 30.

The rearview device 10 includes a first motor 50 fixedly mounted with the support arm 20. The first motor 50 comprises a spindle 51 adapted to rotate about a first geometric axis R with respect to the support arm 20.

The rearview device 10 includes a support frame 60 fixedly mounted with the main shaft 51. The support frame is rotated about the first geometric axis R from at least a first angular position to at least a second angular position, as shown in particular in fig. 6-8.

The rearview device 10 includes an actuator 70 mounted on the support frame 60. The actuator 70 is electrically connected to the first motor 50 or, alternatively, to a second motor, not shown in the figures.

The actuator 70 is fixedly mounted on a portion of the housing 30, and the actuator 70 is adapted to rotate about a second geometric axis S and a third geometric axis T, wherein the second geometric axis S is perpendicular to the third geometric axis T.

The actuator 70 moves together with the support frame 60.

The housing 30 rotates about the first, second and third geometric axes R, S, T to switch between a plurality of angular positions relative to the support arm 20, as shown in particular in fig. 3-8.

The housing 30 contains and protects the rotation mechanism including the first motor 50 and the actuator 70.

The actuator 70 is fixedly mounted on a support 37 of the housing 30, wherein the support 37 is fixedly mounted on the housing 30.

The support 37 of the housing 30 is mounted inside the housing 30 in the direction of forward travel of the vehicle.

The support frame 60 includes a support 61. Said actuator 70 is rotatably mounted on said support 61 of said support frame 60 in a manner rotating about said second geometric axis S and about said third geometric axis T.

Specifically, as shown in fig. 11, the support 61 for the actuator 70 includes a hemispherical portion 62 and a base portion 63. Said hemispherical portion 62 comprises at least one through hole adapted to allow a secure engagement between said actuator 70 and said support 37 of the casing 30. Said base 63 comprises a flat wall adapted to be securely mounted with the body 65 of said support frame 60, said support frame comprising a portion 68 having elements complementary in shape to said base 63 of the support 61, so that said support frame and the support can be securely mounted together.

The base 63 and the complementary portion 68 of the body 65 of the support frame 60 are directed towards the direction of advance of the vehicle, opposite to that of the mirror 40.

The main body 65 of the support frame 60 comprises at least one through hole 64 to allow the entry of said spindle 51 of the first motor 50. The through hole 64 comprises at least one engagement element 66, the shape of which is complementary to the corresponding at least one engagement element 56 of said spindle 51, so that the spindle 51 and the support frame 60 rotate integrally with respect to the support arm 20.

The main body 65 of the support frame 60 comprises a cavity 67 for housing said first motor 50.

The support 61 of the support frame 60 is advantageously mounted in the opposite direction with respect to the mirror 40, i.e. in the direction of movement of the vehicle, so as to better protect it from deliberate damage or impacts.

In particular, as shown in fig. 3-6, 9, the support arm 20 includes a base support 26. The first motor 50 is fixedly mounted above the base support 26. The first geometric axis R is perpendicular to the base support 26.

The support arm 20 comprises a base 25 suitable for assembling the housing 30 and a stem 27, the stem 27 comprising a lower portion firmly mounted with the base 25 and an upper portion forming the base support 26. The base support 26 is flat to allow for a fixed engagement with the first motor 50.

Preferably, as shown in fig. 3-5, said third geometric axis T is parallel to said first geometric axis R.

Alternatively, the third geometric axis T may be perpendicular to the ground and the first geometric axis R may be perpendicular to the base support 26, as shown in fig. 9.

Said housing 30 comprises a lower portion comprising a through hole 32 which allows the rod 27 to enter and has a sufficient width to avoid interference with the rod 27 when the housing 30 is rotated on said three geometric axes R, S, T.

In particular, as shown in figures 1, 3-5, 9, the support arm 20 comprises a hollow cavity 21 hollow in the body of the support arm 20, which allows the insertion of a cable electrically connected to the vehicle. The support base 25 comprises a through hole communicating with the cavity 21 of the support arm 20 for the passage of electrical cables. The cable is electrically connected to the first motor 50 and the actuator 70.

Advantageously, the rearview device 10 of the present invention is more compact, safer, stronger, more protected, less prone to breakage, it allows the driver of the motor vehicle to see the complete field of view, it allows the shape of the support arm 20 and the housing 30 to be chosen, allowing the vehicle to have better aerodynamic characteristics and therefore lower fuel consumption and/or better vehicle performance, solving the drawbacks of the prior art.

Advantageously, the housing 30 may be smaller because the mirror 40 is fixed with the housing 30 and the rotation mechanisms 50, 70 of the housing 30 on the three axes R, S, T are smaller.

Advantageously, the entire rotation mechanism 50, 70 is inside the housing 30 and the only through hole 32 faces downwards to allow the passage of the rod 27 of the support arm 20.

Advantageously, the entire rotation mechanism 50, 70 is inside the housing 30 and prevents tampering with a screwdriver and/or lever to separate the housing 30.

Advantageously, the fact that the mirror 40 is engaged with the housing 30 and not directly with the rotation mechanism 50, 70 allows for a more robust, safe and durable rearview device 10.

Alternatively, the actuator 70 may be mounted in the direction of the mirror 40, as shown in fig. 12 and 13. In this alternative, the support 61 of the support frame 60 comprises a mounting cavity for mounting said actuator 70. In this alternative, the third rotation axis T rotates with respect to the first rotation axis R, as shown in particular in fig. 12.

Alternatively, the mirror 40 includes at least a translucent portion 45 and the housing 30 includes a camera 90 mounted inside the housing 30, as particularly shown in FIG. 13. The translucent portion 45 of the mirror 40 allows the exterior of the mirror 40 to be viewed from the interior of the mirror 40. The camera 90 may also be mounted in the rearview device 10 of fig. 1. Advantageously, the camera 90 is firmly mounted on the casing 30 thanks to the fact that: it is the housing 30 that rotates on the three axes of rotation R, S, T rather than the mirror 40 as in the prior art.

The invention thus conceived is susceptible of numerous modifications and variations, all falling within the same inventive concept; moreover, all the details may be replaced with technically equivalent elements. In practice, the materials used, as well as the dimensions, may be of any type according to the technical requirements.
