[0001] The utility model relates to the technical field of automobile parts, in particular to a rearview mirror and a vehicle. Background Art

[0002] The rearview mirror of a vehicle allows the driver to observe the condition of the vehicle behind the vehicle. Since the rearview mirror is installed at the outermost side of the vehicle, it is easily bumped and hit, which makes the connecting axis of the rearview mirror used to connect the mirror base and the lens easily damaged.

[0003] In the related art, the connecting shaft is fixed to the base bracket of the mirror seat by screws, but the bearing capacity of the connecting shaft on the base bracket is relatively limited, resulting in the abuse force of the rearview mirror not meeting the standard. Utility Model Content

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0039] In the related art, the connecting shaft and the base bracket are fixed only by the abutment of the end faces and screw connection, resulting in that the bearing capacity of the connecting shaft on the base bracket is still relatively limited, causing the abuse force of the rearview mirror to fail to meet the standard.

[0040] Based on this, the utility model provides a rearview mirror 100 that can improve the bearing capacity of the connecting shaft 10 on the base bracket 20. The structure of the rearview mirror 100 of the utility model is described in detail below in conjunction with specific embodiments.

[0041] See also Figures 1 to 4 The rearview mirror 100 includes a connecting shaft 10 and a base bracket 20. The base bracket 20 cooperates with the connecting shaft 10 along the circumference of the connecting shaft 10, and the base bracket 20 abuts against the connecting shaft 10 along the radial direction of the connecting shaft 10 to limit the radial movement of the connecting shaft 10 relative to the base bracket 20 along the connecting shaft 10. The connecting shaft 10 is provided with a first limiting portion 11, and the base bracket 20 is provided with a second limiting portion 21. The first limiting portion 11 and the second limiting portion 21 abut against each other to limit the rotation of the connecting shaft 10 relative to the base bracket 20 around the axis of the connecting shaft 10.

[0042] Specifically, the rearview mirror 100 further includes a mirror housing 30 and a base housing 40, wherein the mirror housing 30 is rotatably connected to the connecting shaft 10, the base bracket 20 is accommodated in the base housing 40, one end of the base bracket 20 is connected to the connecting shaft 10, and the other end of the base bracket 20 is connected to the vehicle body, and the mirror housing 30 can rotate relative to the base bracket 20. The external force can be transmitted to the connecting shaft 10 and the base bracket 20 through the mirror housing 30.

[0043] In the embodiment of the utility model, on the first aspect, the base bracket 20 cooperates with the connecting shaft 10 along the circumferential direction of the connecting shaft 10, and the base bracket 20 abuts against the connecting shaft 10 along the radial direction of the connecting shaft 10, so that the base bracket 20 can play a radial limiting role on the connecting shaft 10, limiting the radial movement of the connecting shaft 10 relative to the base bracket 20 along the connecting shaft 10, when the external force passes through the connecting shaft 10 and is transmitted to the base bracket 20 along the radial direction of the connecting shaft 10, the base bracket 20 can resist the external force along the radial direction, allowing the connecting shaft 10 to withstand a large radial force on the base bracket 20; on the second aspect, the base bracket 20 can play a circumferential limiting role on the connecting shaft 10 through the mutual abutment of the first limiting portion 11 and the second limiting portion 21, when the external torque passes through the connecting shaft 10 and is transmitted to the base bracket 20 along the circumferential direction of the connecting shaft 10, the base bracket 20 can offset the torque along the circumferential direction, so that the connecting shaft 10 can withstand a large circumferential force on the base bracket 20. Through the above arrangement, the bearing capacity of the connecting shaft 10 on the base bracket 20 is improved, and the structural strength between the connecting shaft 10 and the base bracket 20 is good, so that the rearview mirror 100 can withstand greater abuse force.

[0044] In some embodiments, the base bracket 20 defines a limiting groove 22, the lower end of the connecting shaft 10 extends into the limiting groove 22, and the outer wall of the lower end of the connecting shaft 10 is radially matched with the inner wall of the limiting groove 22, that is, the inner wall of the limiting groove 22 surrounds the lower end of the connecting shaft 10 along the circumference of the connecting shaft 10, and the inner wall of the limiting groove 22 abuts against the connecting shaft 10 along the radial direction of the connecting shaft 10. When an external force passes through the connecting shaft 10 and is transmitted to the base bracket 20 along the radial direction of the connecting shaft 10, the inner wall of the limiting groove 22 can resist the external force along the radial direction.

[0045] Among them, the inner wall of the limit groove 22 can be continuous along the circumference of the connecting shaft 10, or can be distributed at intervals along the circumference of the connecting shaft 10. It only needs that the inner wall of the limit groove 22 can radially cooperate with the lower end of the connecting shaft 10 and limit the radial movement of the connecting shaft 10 relative to the base bracket 20 along the connecting shaft 10.

[0046] In some other embodiments, radial fit between the connecting shaft 10 and the base bracket 20 can also be achieved by other means. For example, part of the base bracket 20 extends into the axial hole of the connecting shaft 10, and the part of the base bracket 20 extending into the axial hole radially fits with the inner wall of the axial hole.

[0047] In some embodiments, the outer wall of the lower end of the connecting shaft 10 and the inner wall of the limiting groove 22 are both in the shape of a cone. In this way, the inner wall of the limiting groove 22 can guide the lower end of the connecting shaft 10, and the lower end of the connecting shaft 10 can be inserted into the limiting groove 22 along the inner wall of the limiting groove 22. While achieving radial limitation of the connecting shaft 10, it can also facilitate the assembly of the connecting shaft 10 on the base bracket 20.

[0048] Specifically, the outer wall of the lower end of the connecting shaft 10 and the inner wall of the limiting groove 22 are both in the shape of an inverted frustum.

[0049] In some embodiments, one of the first limiting portion 11 and the second limiting portion 21 is a protrusion and the other is a groove, the protrusion is inserted into the groove, and the cooperation between the protrusion and the groove can limit the rotation of the connecting shaft 10 relative to the base bracket 20 to achieve circumferential cooperation between the connecting shaft 10 and the base bracket 20.

[0050] Specifically, the protrusion and the groove are both trapezoidal, so that the groove can guide the protrusion, and the protrusion can be inserted into the groove along the inclined surface of the trapezoidal groove, which can not only achieve circumferential limitation of the connecting shaft 10, but also facilitate the assembly of the connecting shaft 10 on the base bracket 20.

[0051] In some other embodiments, the first limiting portion 11 and the second limiting portion 21 may also be other structures that can achieve circumferential fit between the connecting shaft 10 and the base bracket 20. For example, the first limiting portion 11 is a square column, and the second limiting portion 21 is a square groove, and the square column is inserted into the square groove. For another example, the first limiting portion 11 is a first hole position, and the second limiting portion 21 is a second hole position. The first hole position and the second hole position both extend radially along the connecting shaft 11, and the first hole position and the second hole are connected. By inserting a pin in the first hole position and the second hole, the circumferential fit between the connecting shaft 10 and the base bracket 20 can be achieved.

[0052] In some embodiments, the first limit portion 11 and the second limit portion 21 are both distributed at intervals along the circumference of the connecting shaft 10. In this way, the forces on the connecting shaft 10 and the base bracket 20 in the circumferential direction of the connecting shaft 10 can be balanced, avoiding the circumferential force between the connecting shaft 10 and the base bracket 20 from being concentrated at a certain position, which is beneficial to maintaining the structural stability of the connecting shaft 10 and the base bracket 20 when subjected to force.

[0053] In some embodiments, a support column 12 extends from the outer wall of the connecting shaft 10 toward the base bracket 20, and the support column 12 is connected to the base bracket 20. The support column 12 can support the connecting shaft 10, so that the connecting shaft 10 can be firmly installed on the base bracket 20, thereby improving the structural strength of the connecting shaft 10.

[0054] In some embodiments, the support column 12 extends from the upper end of the connecting shaft 10 toward the lower end of the connecting shaft 10. In this way, the support column 12 can directly support the upper end surface of the connecting shaft 10, so that the connecting shaft 10 can withstand a larger axial force on the base bracket 20.

[0055] Specifically, the upper end of the support column 12 supports the upper end surface of the connecting shaft 10 , and the base bracket 20 supports the lower end of the support column 12 .

[0056] In some embodiments, multiple support columns 12 are distributed at intervals along the circumference of the connecting shaft 10 so that the multiple support columns 12 can provide balanced support in the circumferential direction of the connecting shaft 10, thereby ensuring the axial bearing capacity of the connecting shaft 10 on the base bracket 20, which is beneficial to maintaining the structural stability of the connecting shaft 10 when subjected to stress.

[0057] In some embodiments, the support column 12 is threadedly connected to the base bracket 20 so that the connecting shaft 10 is fixed as a whole on the base bracket 20, and there is no need to provide an additional structure on the connecting shaft 10 for threadedly connecting the connecting shaft 10 and the base bracket 20. That is, the support column 12 serves as both a structure for connecting the connecting shaft 10 to the base bracket 20 and a structure for supporting the connecting shaft 10 and improving the axial bearing capacity of the connecting shaft 10.

[0058] See also Figure 5 In some embodiments, the rearview mirror 100 also includes a driving motor 50, the driving motor 50 includes a first motor and a second motor, the first motor includes a first motor body and a first output shaft connected to the first motor body, the second motor includes a second motor body and a second output shaft connected to the second motor body, the first output shaft is fixed to the connecting shaft 10, the second output shaft is fixed to the first motor body, and the axis of the first output shaft is perpendicular to the axis of the second output shaft.

[0059] The axis of the first output shaft also coincides with the axis of the connecting shaft 10. When the rearview mirror 100 is mounted on the vehicle body, the axis of the first output shaft is parallel to the horizontal plane, and the axis of the second output shaft is parallel to the vertical direction.

[0060] Specifically, the rearview mirror 100 further includes a substrate 60 , the driving motor 50 is accommodated inside the substrate 60 , and the second motor body of the driving motor 50 is fixed to the mirror housing 30 through the substrate 60 .

[0061] When the first motor is started, since the connecting shaft 10 is fixed to the base bracket 20, the first output shaft is fixed to the connecting shaft 10, and the second output shaft is fixed to the first motor body, the first motor body can drive the second motor, the base plate 60 and the mirror housing 30 to rotate relative to the first output shaft around the axis of the first output shaft, thereby realizing the left and right swing of the mirror housing 30 relative to the seat housing 40 around the connecting shaft 10. In this process, the first motor will output a circumferential force to the connecting shaft 10 through the first output shaft, and the base bracket 20 can offset the circumferential force through the circumferential limiting effect with the connecting shaft 10, so that the connecting shaft 10 is always firmly fixed to the base bracket 20 in the circumferential direction; When the second motor is started, since the second output shaft is fixed to the first motor body and the first motor body is fixed to the connecting shaft 10 through the first output shaft, the second motor body can drive the base plate 60 and the mirror housing 30 to rotate relative to the second output shaft around the axis of the second output shaft, thereby realizing the up and down swing of the mirror housing 30 relative to the seat housing 40 around the connecting shaft 10. In this process, the second motor will output radial force to the connecting shaft 10 through the second output shaft, the first motor body and the first output shaft, and the base bracket 20 can offset the radial force through the radial limiting effect with the connecting shaft 10, so that the connecting shaft 10 is always firmly fixed to the base bracket 20 radially. That is to say, whether the force generated by the driving motor 50 is transmitted to the connecting shaft 10, or the external force transmits the force to the connecting shaft 10 through the mirror housing 30, the base plate 60, and the driving motor 50, the radial matching and circumferential matching structure between the connecting shaft 10 and the base bracket 20 can offset the force, ensuring that the connecting shaft 10 has a good bearing capacity on the base bracket 20, and the rearview mirror 100 has a high anti-abuse ability.

[0062] The embodiment of the utility model further provides a vehicle, and the vehicle includes the rearview mirror 100 as described above.

[0063] The vehicle of the embodiment of the utility model also has the advantages of the above-mentioned rearview mirror 100, which will not be described in detail here.

It can be understood that the vehicle provided in the embodiment of the utility model also includes other structures for realizing the functions of the vehicle, including but not limited to the body and the like.

[0065] It should be noted that the vehicle referred to in the embodiments of the present utility model may be a private car, such as a sedan, SUV, MPV or pickup truck. The vehicle may also be an operating vehicle, such as a van, bus or truck. The vehicle may be a gasoline vehicle or a new energy vehicle.
