Description

Technical Field

[0001] This application relates to the field of rearview mirror adjustment technology, and in particular to a rearview mirror adjustment device. Background Technology

[0002] As the automotive industry continues to develop, exterior rearview mirrors, as crucial components for ensuring driving safety, are receiving increasing attention for their design rationality and functionality. Folding rearview mirrors can be retracted when navigating narrow roads, improving the vehicle's maneuverability. When the driver leaves the vehicle, the mirrors can also be folded up, protecting the mirror surface and reducing parking space requirements, effectively preventing scratches.

[0003] Existing exterior rearview mirror folding devices typically use manual or motor-driven adjustment shafts to rotate, thereby rotating the rearview mirrors. The structure is relatively simple and performs well in terms of reliability.

[0004] The existing technical solutions mentioned above have the following drawbacks: the existing exterior rearview mirror folding device has poor stability after adjustment, and when the vehicle vibrates violently, it is easy to cause the rotating shaft to rotate, causing the rearview mirror angle to change. Utility Model Content

[0005] This application provides a rearview mirror adjustment device to improve the stability of the rearview mirror after adjustment.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A rearview mirror adjustment device includes a rotating base, a rotating sleeve fitted on the rotating base, a housing fixedly connected to the rotating sleeve, a mirror adjustment assembly disposed inside the housing, a lens mounted on the mirror adjustment assembly, a worm gear fixedly connected to the rotating base, a fixed column fixedly connected inside the housing, a motor mounted on the fixed column, a worm gear connected to the output shaft of the motor, a section of the worm gear being machined into a tapered shape, and the worm gear meshing with the worm wheel.

[0008] By adopting the above technical solution, the motor rotation drives the worm gear to rotate, thereby causing the housing to rotate on the rotating seat, realizing the folding or unfolding of the rearview mirror. The worm gear is processed into a conical shape, which can reduce the space occupied by the worm gear and worm wheel, while increasing the meshing length of the worm gear and worm wheel, ensuring the stability of the meshing of the worm gear and worm wheel. After the rearview mirror is adjusted, the meshing of the worm gear and worm wheel has a self-locking characteristic, which can improve the stability of the rearview mirror after adjustment and reduce the rotation of the housing on the rotating seat when the vehicle is bumpy.

[0009] Optionally, a mounting plate is rotatably mounted on the fixed column, the mounting plate is connected to the motor, and a first elastic element is sleeved on the fixed column, one end of the first elastic element is connected to the fixed column, and the other end of the first elastic element is connected to the mounting plate.

[0010] By adopting the above technical solution, the motor on the mounting plate can swing on the fixed column. When the rearview mirror is manually rotated or impacted, the wear between the worm gear and the worm can be reduced. After rotation, the first elastic element pushes the motor and the worm to reset, thus extending the service life of the rearview mirror adjustment device.

[0011] Optionally, a limit block is fixedly attached to the worm gear.

[0012] By adopting the above technical solution, the limiting block can block the worm gear after the rearview mirror is folded or unfolded, reducing the risk of damage caused by excessive rotation angle of the rearview mirror.

[0013] Optionally, a positioning ring is fitted on the rotating seat, the positioning ring is slidably connected to the rotating seat, a positioning post is fixedly connected to the positioning ring, one end of the positioning post is machined into a spherical surface, a positioning groove is opened on the rotating sleeve for the fixing post to be embedded, a second elastic element is fixedly connected to the positioning ring, and one end of the second elastic element abuts against the worm gear.

[0014] By adopting the above technical solution, the positioning pin on the positioning ring is embedded in the positioning groove of the rotating sleeve. When the rearview mirror rotates, the positioning ring is lifted up, and the second elastic element contracts and stores energy. When the rearview mirror rotates to fold or unfold, the second elastic element pushes the positioning ring to make the positioning pin embed in the positioning groove. This can increase the stability of the rearview mirror after folding or unfolding, reduce the rotation of the rearview mirror caused by vibration, and reduce the risk of damage caused by excessive rotation angle of the rearview mirror.

[0015] Optionally, a positioning block is fixedly connected to the rotating sleeve.

[0016] By adopting the above technical solution, the positioning block can prevent the rearview mirror from continuing to rotate after it is deployed, reducing the risk of damage caused by excessive rotation when the rearview mirror is deployed.

[0017] Optionally, a cleaning pipe is provided inside the rotating seat, one end of which is connected to a water spray pipe. The water spray pipe is fixed to the housing, and a nozzle is installed on the water spray pipe.

[0018] By adopting the above technical solution, dirt on the rearview mirror lens can be washed away during driving, making it easier to clean the rearview mirror lens.

[0019] Optionally, the housing is provided with a drainage hole.

[0020] By adopting the above technical solution, rainwater or the washing rack can be discharged from the drain hole after rain or after washing the rearview mirror, reducing liquid residue at the connection between the housing and the lens. When the vehicle is in motion, the high-speed airflow passes through the drain hole, which can accelerate the discharge of liquid from the bottom of the housing and the bottom of the drain hole, ensuring the safety of the vehicle while driving.

[0021] Optionally, a winding reel is rotatably disposed inside the housing.

[0022] By adopting the above technical solution, the winding reel facilitates the organization of the wiring inside the housing and reduces friction of the wiring when the rearview mirror is folded.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a worm and a worm wheel, and machining the worm into a conical shape, the space occupied by the worm and worm wheel can be reduced, while increasing the meshing length of the worm and worm wheel, ensuring the stability of the meshing of the worm and worm. After the rearview mirror is adjusted, the meshing of the worm wheel and worm has a self-locking characteristic, which can improve the stability after the rearview mirror is adjusted and reduce the rotation of the housing on the rotating seat when the vehicle is bumpy.

[0025] 2. By setting a fixed column, a mounting plate and a first elastic element, the motor on the mounting plate can swing on the fixed column. When the rearview mirror is manually rotated or impacted, the wear between the worm gear and the worm can be reduced. After rotation, the first elastic element pushes the motor and the worm to reset, thus extending the service life of the rearview mirror adjustment device.

[0026] 3. By setting a limit block, the limit block can block the worm gear after the rearview mirror is folded or unfolded, reducing the risk of damage caused by excessive rotation angle of the rearview mirror. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a rearview mirror adjustment device, referring to... Figure 1 and Figure 2 The rearview mirror adjustment device includes a rotating seat 1, one end of which is connected to the vehicle, and a rotating sleeve 2 is fitted on the other end of the rotating seat 1. A housing 3 is integrally formed on the top of the rotating sleeve 2. A mirror adjustment component 4 is provided inside the housing 3. A lens 5 is installed on the side of the mirror adjustment component 4 away from the housing 3. The lens 5 is embedded in the housing 3. A heating mesh 51 is installed on the side of the lens 5 facing the housing 3.

[0034] Reference Figure 2 and Figure 3 A worm gear 11 is bolted to one end of the rotating seat 1 near the housing 3. The side of the worm gear 11 near the rotating seat 1 is machined into a smooth plane. A fixed column 31 is integrally formed inside the housing 3. A mounting plate 32 is rotatably connected to the top of the fixed column 31. A first elastic element 33 is sleeved on the section of the fixed column 31 near the mounting plate 32. In this embodiment, the first elastic element 33 is a planar spiral spring. One end of the first elastic element 33 is snapped into the fixed column 31, and the other end is snapped into the mounting plate 32. A motor 34 is mounted on the mounting plate 32. The output shaft of the motor 34 is connected to a worm 35 by a key. The section of the worm 35 away from the motor 34 is machined into a tapered shape. The worm 35 meshes with the worm gear 11. A limit block 12 is integrally formed on the side of the worm gear 11 near the rotating seat 1. Two limit blocks 12 are spaced apart. Both limit blocks 12 are located at the connection between the plane and the teeth of the worm gear 11.

[0035] Reference Figure 3 and Figure 4 A positioning ring 13 is fitted inside the housing 3 of the rotating seat 1. The positioning ring 13 can slide along the length of the rotating seat 1. The side of the positioning ring 13 facing the rotating sleeve 2 abuts against the rotating sleeve 2. A positioning post 131 is integrally formed on the side of the positioning ring 13 facing the rotating sleeve 2. The end of the positioning post 131 away from the positioning ring 13 is machined into a spherical shape. Two positioning posts 131 are spaced apart. The top of the rotating sleeve 2 is machined into a positioning groove 21 for the positioning post 131 to be inserted. Three positioning grooves 21 are spaced apart. A second elastic element 14 is fixedly connected to the side of the positioning ring 13 away from the rotating sleeve 2. In this embodiment, the second elastic element 14 is a spring. The second elastic element 14 is fitted onto the rotating seat 1. The other end of the second elastic element 14 abuts against the worm gear 11. A positioning block 22 is integrally formed on the top of the rotating sleeve 2 away from the motor 34.

[0036] Reference Figure 1The rotating base 1 has a cavity through which the power supply line and water pipe pass. A cleaning pipe 6 is installed inside the rotating base 1. One end of the cleaning pipe 6 is connected to the vehicle's washing pump, and the other end of the cleaning pipe 6 is connected to a water spray pipe 61. The water spray pipe 61 is fixed to the top of the housing 3 by bolts. A nozzle 62 is installed on the water spray pipe 61. Multiple nozzles 62 are spaced apart. The end of the nozzle 62 away from the water spray pipe 61 faces the lens 5 away from the housing 3. A winding reel 8 with the power supply line and water pipe is fixed to the housing 3 by bolts. The wires of the water spray pipe 61 and the housing 3 are all wrapped around the winding reel 8 and connected to the vehicle. A drain hole 7 is opened at the bottom of the housing 3. In this embodiment, the drain hole 7 is a strip-shaped hole. The drain hole 7 is located on the side of the lens 5 away from the housing 3.

[0037] When using this rearview mirror adjustment device, the control motor 34 rotates, driving the worm gear 35 to drive the worm wheel 11 to rotate, thereby causing the housing 3 to rotate on the rotating seat 1, realizing the folding or unfolding of the rearview mirror. The worm gear 35 is machined into a tapered shape, which can reduce the space occupied by the worm gear 35 and the worm wheel 11, while increasing the meshing length of the worm gear 35 and the worm wheel 11, ensuring the stability of the meshing between the worm wheel 11 and the worm gear 35. After the rearview mirror is adjusted, the meshing between the worm wheel 11 and the worm gear 35 has a self-locking characteristic, which can improve the stability of the rearview mirror after adjustment and reduce the rotation of the housing 3 on the rotating seat 1 when the vehicle is bumpy.

[0038] When this rearview mirror adjustment device is used, the motor 34 on the mounting plate 32 can swing on the fixed column 31. When the rearview mirror is manually rotated or impacted, the wear between the worm gear 11 and the worm 35 can be reduced. After rotation, the first elastic element 33 pushes the motor 34 and the worm 35 to reset, thus extending the service life of the rearview mirror adjustment device.

[0039] When using this rearview mirror adjustment device, the limiting block 12 can block the worm gear 35 after the rearview mirror is folded or unfolded, reducing the risk of damage caused by excessive rotation angle of the rearview mirror. The positioning pin 131 on the positioning ring 13 is embedded in the positioning groove 21 of the rotating sleeve 2. When the rearview mirror rotates, the positioning ring 13 is lifted, and the second elastic element 14 contracts and stores energy. When the rearview mirror rotates to fold or unfold, the second elastic element 14 pushes the positioning ring 13 to make the positioning pin 131 embed into the positioning groove 21, which can increase the stability of the rearview mirror after folding or unfolding, reduce the rotation of the rearview mirror caused by vibration, and at the same time reduce the risk of damage caused by excessive rotation angle of the rearview mirror. After the rearview mirror is unfolded, the positioning block 22 can prevent the rearview mirror from continuing to rotate, reducing the risk of damage caused by excessive rotation when the rearview mirror is unfolded.

[0040] When using this rearview mirror adjustment device, the vehicle's washing pump pumps cleaning agent into the cleaning pipe 6. The cleaning agent is sprayed from multiple nozzles 62 on the spray pipe 61, which can wash away dirt on the rearview mirror lens 5 during driving, making it easier to clean the rearview mirror lens 5. The heating mesh 51 can raise the temperature of the lens 5, which can evaporate rainwater, melt frost, and suppress fog, ensuring the rearview mirror is clear in rain, snow, fog, or low-temperature environments, improving vehicle driving safety. After rain or washing the rearview mirror, rainwater or the washing rack can be discharged from the drain hole 7, reducing liquid residue at the connection between the housing 3 and the lens 5. When the vehicle is driving, the high-speed airflow passes through the drain hole 7, which can accelerate the discharge of liquid from the bottom of the housing 3 and the bottom of the drain hole 7, ensuring vehicle driving safety. The cable reel 8 facilitates the organization of the wiring inside the housing 3 and reduces friction of the wiring when the rearview mirror is folded.

[0041] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
