Description

Technical Field

[0001] The present application relates to an automobile interior rearview mirror device, and in particular to a novel automobile interior rearview mirror. Background Art

[0002] A rearview mirror is a mirror mounted on the roof of a vehicle, primarily designed to help the driver clearly see vehicles and pedestrians behind them while driving. Typically located inside the cab, it allows the driver to observe what's behind the vehicle and ensure driving safety. Depending on their function and needs, rearview mirrors can be categorized into various types, including manual anti-glare, automatic anti-glare, and streaming media.

[0003] Manual anti-glare means that the driver can manually bend the ordinary interior rearview mirror or wedge-shaped lens. When the light of the rear vehicle shines on the interior rearview mirror inside the car and is reflected to affect the driver's driving, the driver can manually bend the interior rearview mirror to adjust its angle to avoid glare and ensure safe driving.

[0004] Automatic anti-glare usually automatically adjusts and darkens the color of the lens when encountering rear vehicle lights to avoid dazzling the driver.

[0005] To sum up, the manual anti-glare interior rearview mirror needs to be manually turned by the driver when in use, and the driver's hands need to continuously adjust the angle of the interior rearview mirror, which can easily affect the driver's safe driving; and the automatic anti-glare interior rearview mirror, although it can play an anti-glare function, is relatively expensive and is currently only used in some relatively expensive cars. Based on this, the inventor has developed a new type of automobile interior rearview mirror. Utility Model Content

[0006] In order to solve the above technical problems, the present application provides a new type of automobile interior rearview mirror, which is designed to achieve an anti-glare effect by hingedly connecting a reversing seat to a fixed seat and using a switch to control a driving assembly to drive the reversing seat to swing on the fixed seat. This method adjusts the angle of the lens and eliminates the need to manually bend the interior rearview mirror, thereby reducing the impact of adjusting the interior rearview mirror on the driver's driving. At the same time, the structure is simple, the cost is low, and it is easy to promote.

[0034] The present application is further described in detail below with reference to the accompanying drawings.

[0035] The embodiment of the present application discloses a novel automobile interior rearview mirror.

[0036] Reference Figures 1 to 3 The novel automobile interior rearview mirror includes a mirror housing 1, a reversing seat 2, a fixing seat 3, a driving assembly 4, a switch 5, a mirror support plate 6 and a lens 7.

[0037] The mirror housing 1 is the shell of the interior rearview mirror and serves as a carrier for installing various components.

[0038] The reversing seat 2 is detachably connected and fixed to the interior of the mirror housing 1 , wherein the detachable connection includes but is not limited to plug-in connection, clip-on connection or bolt connection.

[0039] Reference Figures 1 to 3 The rear end of the mirror housing 1 is provided with a through hole, through which the fixing seat 3 is hinged to the reversing seat 2. Specifically, in order to enable the reversing seat 2 to be adjusted in all directions on the fixing seat 3, refer to Figure 2 The fixed seat 3 and the reversing seat 2 are ball-hinged, and the fixed seat 3 and the reversing seat 2 can adopt an interference fit. When no external force is applied to the mirror housing 1 or the reversing seat 2, the reversing seat 2 can remain fixed on the fixed seat 3. When external force is applied to the mirror housing 1 or the reversing seat 2, the reversing seat 2 can swing in the corresponding direction on the fixed seat 3.

[0040] Reference Figure 3 The driving component 4 is arranged in the mirror housing 1 and is connected to the reversing seat 2. The driving component 4 is used to drive the reversing seat 2 to swing on the fixing seat 3 to adjust the angle between the mirror housing 1 and the reversing seat 2.

[0041] Specifically, the driving assembly 4 includes a transmission part 41 and a power part 42 . The transmission part 41 is connected to the reversing seat 2 , and the power part 42 is connected to the transmission part 41 . The power part 42 drives the reversing seat 2 to swing on the fixed seat 3 through the transmission part 41 .

[0042] Reference Figure 4 The transmission part 41 includes a partially toothed gear 411, a transmission shaft 412 and a transmission gear 413. The partially toothed gear 411 is formed at the bottom of the reversing seat 2, and the transmission shaft 412 is rotatably connected to the inside of the mirror housing 1. The transmission gear 413 is installed on the transmission shaft 412, and the transmission gear 413 is engaged with the partially toothed gear 411. The transmission gear 413 and the transmission shaft 412 can also adopt an integrated gear shaft.

[0043] The power section 42 includes a power member 421, a power gear 422, and an input gear 423. The power member 421 can be a reciprocating motor or a micro servo motor. The power gear 422 is mounted on the output shaft of the power member 421, and the input gear 423 is mounted on the transmission shaft 412 and meshes with the power gear 422. The power member 421 drives the power gear 422 to rotate, which in turn drives the input gear 423 to rotate. The transmission shaft 412 rotates with the input gear 423, and the transmission gear 413 rotates together with the transmission shaft 412. At the same time, the transmission gear 413 drives the reversing seat 2 to swing on the fixed seat 3 through the partial tooth gear 411.

[0044] Further, refer to Figure 4 and Figure 5 In order to limit the swing angle of the transmission shaft 412, the outer wall of the transmission shaft 412 is also formed with a first limiting protrusion 4121 and a second limiting protrusion 4122. The first limiting protrusion 4121 and the second limiting protrusion 4122 are respectively located on both sides of the axial direction of the transmission shaft 412, and the first limiting protrusion 4121 and the second limiting protrusion 4122 are staggered on the transmission shaft 412 and are not located on the same plane.

[0045] In addition, two limit seats 8 are provided inside the mirror housing 1. The two limit seats 8 are respectively located directly below the two sides of the transmission shaft 412 in the axial direction. The two limit seats 8 can be integrally formed with the mirror housing 1 by injection molding. The limit seats 8 are formed with groove-shaped placement portions, and the transmission shaft 412 can be placed in the placement portions of the two limit seats 8. When the second limiting protrusion 4122 abuts against the limiting seat 8 directly below, a first gap is formed between the first limiting protrusion 4121 and the adjacent side end of the limiting seat 8 directly below; when the first limiting protrusion 4121 abuts against the limiting seat 8 directly below, a second gap is formed between the second limiting protrusion 4122 and the adjacent side end of the limiting seat 8 directly below. The swing angle of the first gap and the swing angle of the second gap are both the swing angles of the transmission shaft 412. In actual settings, the swing angle of the reversing seat 2 on the fixed seat 3 is small. Therefore, the angle at which the transmission shaft 412 can rotate on the limiting seat 8 is also small. In actual application, the swing angle of the reversing seat 2 on the fixed seat 3 is generally 3 to 5 degrees. The swing angle of the transmission shaft 412 in the limiting seat 8 can be set according to actual needs, so that the reversing seat 2 can swing on the fixed seat 3 at an angle of 3 to 5 degrees.

[0046] Reference Figure 4 and Figure 5 The power part 421 is also electrically connected to a circuit board 9, which is installed inside the mirror housing 1, and the circuit board 9 is also electrically connected to a connector 10, which is located outside the mirror housing 1. The connector 10 is used to electrically connect to the car's power system, and the outside of the connector 10 can be plugged or snapped onto the fixing seat 3.

[0047] The switch 5 can be electrically connected to the power member 421 or the circuit board 9. In this embodiment, the switch 5 is electrically connected to the circuit board 9, and the switch 5 controls the opening and closing of the power member 421 through the circuit board 9. The switch 5 can be a touch switch 5 or a voice-activated switch 5. If the switch 5 is a touch switch 5, it can be installed at the bottom of the mirror housing 1, on the steering wheel of the car, or other places that are easily accessible to the driver.

[0048] The mirror support plate 6 is fixed to the mirror housing 1 via a detachable connection, wherein the detachable connection includes but is not limited to plugging, snapping, or bolting. The lens 7 is fixed to the mirror support plate 6 via a detachable connection, wherein the detachable connection includes but is not limited to snapping or bonding. In this embodiment, the lens 7 can be fixed to the mirror support plate 6 via double-sided tape.

[0049] When in use, when it is necessary to adjust the angle of the lens 7, the driver activates the switch 5, and then the circuit board 9 activates the power piece 421. The power piece 421 drives the reversing seat 2 to swing on the fixed seat 3 through the power gear 422, the input gear 423, the transmission shaft 412, the transmission gear 413 and the partial tooth gear 411, so as to adjust the angle of the lens 7 according to the angle and position of the reversing seat 2 on the fixed seat 3. When the transmission shaft 412 rotates, the first limiting protrusion 4121 will gradually abut against the side end of the limiting seat 8 directly below, so that the transmission shaft 412 stops rotating, and the reversing seat 2 stops swinging on the fixed seat 3. When the first limiting protrusion 4121 abuts against the limiting seat 8 directly below, the torque borne by the output shaft of the power piece 421 will gradually increase, so that the current on the circuit board 9 will also increase. When the current on the circuit board 9 increases to the set value, the power piece 421 will be turned off and stop rotating, and the power piece 421 will rotate in the opposite direction when it is started next time.

[0050] When the power piece 421 rotates in the opposite direction, the power piece 421 drives the reversing seat 2 to swing in the opposite direction on the fixed seat 3 through the power gear 422, input gear 423, transmission shaft 412, transmission gear 413 and part of the tooth gear 411, so that the angle and position of the reversing seat 2 on the fixed seat 3 are maintained. When the transmission shaft 412 rotates in the opposite direction, the second limiting protrusion 4122 will gradually abut against the side end of the limiting seat 8 directly below, so that the transmission shaft 412 no longer rotates in the opposite direction, and the reversing seat 2 no longer swings in the opposite direction on the fixed seat 3. When the second limiting protrusion 4122 abuts against the limiting seat 8 directly below, the torque borne by the output shaft of the power piece 421 will gradually increase, so that the current on the circuit board 9 will also increase. When the current on the circuit board 9 increases to the set value, the power piece 421 will be turned off and stop rotating, and the power piece 421 will rotate forward when it starts next time, and so on.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
