Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to an interior rearview mirror assembly. Background Art

[0002] The anti-glare interior rearview mirror is an important safety feature of the car. It can effectively reduce the impact of the strong light from the rear vehicle on the driver's vision and improve the safety of night driving. The working principle of the current manual anti-glare interior rearview mirror is that the manual anti-glare interior rearview mirror usually uses a wedge-shaped mirror with two reflective surfaces: the outer glass and the inner mirror. Under normal conditions, the light is reflected downward through the inner and outer layers. When the driver feels that the light behind is too strong, he can flip the switch under the rearview mirror to flip the mirror upward at a small angle. At this time, the light is reflected through the outer glass with a lower reflectivity, thereby reducing the light intensity and achieving an anti-glare effect.

[0003] However, 1. Most of the traditional manual anti-glare interior rearview mirrors have frames, and the lenses are compressed by the interaction force between the mouth ring and the mirror shell. The frame occupies a large effective area, which makes the interior rearview mirror not beautiful enough and also affects the effective use area.

[0004] 2. The anti-glare opening and closing of the traditional manual anti-glare interior rearview mirror mostly adopts a complex mechanical structure composed of multiple parts, which has a complex structure and poor stability. The simple adjustment lever, when turning the lever to open and close the anti-glare function, contacts the mirror shell surface to surface, so the adjustment sound is very loud and very crisp, and the noise caused by it reduces the comfort of use. Some people add a cushion on the mirror shell, which can solve the problem of loud noise, but the cost will increase, and the cushion is easy to age and fall off, affecting the service life.

[0005] 3. The ball head seat of the traditional manual anti-glare rearview mirror is fastened to the ball head with a spring, and there is a lack of a spring limiting structure. When the mirror body rotates, there is a risk of the spring slipping off, and there is a lack of a limiting structure for the mirror body. When the mirror body rotates, it is easy to have a large deviation, causing the ball head to detach from the ball head seat and easily causing damage to the ball joint structure.

[0028] Example: See Figures 1 to 4An interior rearview mirror assembly includes a mirror housing 1, a lens 2 is installed on the front side of the mirror housing 1, and the rear side is connected to a support 3 through a ball joint structure. Specifically, a mirror support plate 9 is installed on the front side of the mirror housing 1, and the lens 2 is installed on the mirror support plate 9, wherein a double-sided adhesive tape 10 is provided between the lens 2 and the mirror support plate 9, and a plurality of exhaust grooves arranged transversely or longitudinally or staggered are provided on the front side of the mirror support plate 9, and the exhaust grooves run through the edge of the mirror support plate 9, and the lens 2 is attached to the mirror support plate 9 by means of the double-sided adhesive tape 10. The projection of the lens 2 on the front side of the mirror housing 1 completely covers the contour line of the mirror housing 1, thereby forming a frameless interior rearview mirror. By adopting a frameless rearview mirror, the double-sided adhesive tape 10 is added between the lens 2 and the mirror support plate 9, so that the lens 2 is attached to the mirror support plate 9, and the exhaust grooves are provided on the mirror support plate 9, so that no bubbles are generated when the double-sided adhesive tape 10 is attached, thereby making the attachment more firm. In this embodiment, the mirror support plate 9 and the mirror shell 1 adopt a snap-on structure. After the lens 2 is pasted onto the mirror support plate 9, the mirror support plate 9 and the mirror shell 1 are snap-connected, so that the lens 2, the mirror support plate 9, and the mirror shell 1 are assembled. This not only increases the field of view but also makes the mirror more beautiful.

[0029] The ball joint structure includes a ball head 4 formed at the front end of the support 3, and a ball head seat 5 installed in the mirror housing 1, a ball socket is provided at the rear side of the ball head seat 5, and the ball head 4 is rotatably installed in the ball socket, wherein the ball socket is formed by a plurality of elastic plates arranged at intervals and having an arc-shaped inner side, a spring 6 is sleeved on the outer side of the elastic plate so that the inner side of the elastic plate is tightly fitted with the ball head 4, and a first limiting structure for limiting the movement of the spring 6 is provided on the elastic plate. The first limiting structure includes a buckle structure 11 protruding outward at the end of part or all of the elastic plate, and after the spring 6 is sleeved on the outer side of the elastic plate, the buckle structure 11 can fit with one end of the spring 6 to limit the movement of the spring 6. In this embodiment, there are eight elastic plates, four of which are provided with the snap-fit ​​structures 11 facing different directions. When the spring 6 is installed, the spring 6 is sleeved on the outside of the elastic plate by relying on the deformation of the elastic plate. After the elastic plate is reset, the snap-fit ​​structure 11 is abutted against the spring 6, thereby fixing and limiting the spring 6 and preventing the spring 6 from falling off.

[0030] An elastic paddle 7 is installed on the ball head seat 5. The paddle 7 extends from one side of the mirror housing 1 and is provided with a lever 8 at the end. The lever 8 can be moved to cause the paddle 7 to produce elastic deformation and drive the ball head seat 5 to rotate around the ball center of the ball head 4, thereby realizing the opening and closing of the manual anti-glare function. Specifically, the paddle 7 is an L-shaped plate structure, one of which is fixedly connected to the ball head seat 5, and the other is extended from the mirror housing 1 and connected to the lever 8. Specifically, a slot is provided on the opposite sides of the front side of the ball head seat 5, and the two sides of one of the paddles of the paddle 7 are correspondingly inserted into the slot, and the other is bent toward the rear side of the ball head seat 5, and extends from the mirror housing 1 to be connected to the lever 8. The support plate connecting the paddle 7 and the ball head seat 5 is provided with a spherical concave pit that is concave away from the ball socket at the position corresponding to the ball socket. When the ball head 4 is installed in the ball socket, the front side of the ball head 4 fits with the concave pit. In this way, the paddle 7 can be easily assembled with the ball head seat 5, and the pit on the paddle 7 contacts the front side of the ball head 4, and cooperates with the elastic plate to further play an auxiliary limiting and fixing role for the ball head 4, thereby improving the stability of the ball head 4 in the ball socket and preventing the ball head 4 from loosening.

[0031] A noise reduction structure is provided on the rod body of the lever 8. When the lever 8 is turned to rotate, the noise reduction structure can make point contact with the mirror housing 1. The noise reduction structure includes a plurality of hemispherical convex point structures 12 arranged on the lever 8, so that the lever 8 and the mirror housing 1 can achieve point and surface contact, which will reduce the force area, thereby reducing the adjustment noise and reducing the cost.

[0032] A second limiting structure is provided on the support 3 near the ball head 4, which can contact the second limiting structure when the mirror housing 1 rotates, and is used to limit the continued rotation of the mirror housing 1. The second limiting structure includes a plurality of convex ridges 13 provided on the support 3, and when the mirror housing 1 rotates to a preset angle, the convex ridges 13 contact the mirror housing 1, and are used to limit the continued rotation of the mirror housing 1. Specifically, the support 3 is a columnar structure, and the convex ridges 13 are arranged in three intervals and distributed on the left and right sides and the lower side of the support 3 to prevent the mirror housing 1 from rotating and deviating significantly, and to prevent the ball head 4 from falling out of the ball head seat 5.

[0033] During implementation, the mirror support plate is clamped with the mirror shell and abutted or connected to the ball head seat so that it can rotate within a certain angle range. When the anti-glare function needs to be turned on or off, the lever is moved by the plate to drive the ball head seat to rotate, thereby driving the mirror support plate to rotate a certain angle, so that the reflection angle of the lens changes, thereby realizing the adjustment of the anti-glare function.

[0034] The utility model,

[0035] 1. Use frameless lenses to increase the field of view while making the interior rearview mirror assembly more beautiful.

[0036] 2. Good stability during the manual anti-glare opening and closing process.

[0037] 3. When adjusting the lever to open and close, reduce the noise and improve the user experience.

[0038] 4. When the mirror body rotates, keep the ball head, ball head seat and spring connected and tight to prevent the spring from slipping.

[0039] 5. The three limiting ridges on the ball head can effectively solve the problem of large deviation when the mirror body rotates.

[0040] In summary, the utility model adopts a ball socket formed by multiple elastic plates to match the ball head, and a first limiting structure for limiting the movement of the spring is arranged on the elastic plate, which can effectively prevent the spring from falling off and improve the stability of use. At the same time, by arranging a noise reduction structure on the lever that contacts the mirror shell at a point, the noise caused by the collision between the lever and the mirror shell is reduced, and the comfort of use is improved. By arranging a second limiting structure on the support to limit the rotation angle of the mirror shell, the ball joint structure can be better protected, the mirror shell can be prevented from large displacement, and the service life can be extended.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution.
