Description

Technical Field

[0001] This application relates to the field of automotive safety accessories, and in particular to a vehicle rearview mirror assembly and a vehicle. Background Technology

[0002] Rearview mirrors are crucial safety components for drivers to obtain traffic information behind and to the sides of the vehicle while driving. The clarity and range of their field of vision directly affect driving safety. To eliminate blind spots, drivers often attach small wide-angle mirrors to the main mirror surface, thereby expanding the field of vision to some extent. However, in rainy or snowy weather, rainwater, snow, or fog can easily accumulate on the rearview mirror surface, causing blurred images and severely obstructing the driver's view.

[0003] Existing solutions for removing water from rearview mirrors mainly include built-in heating wires or surface spraying with hydrophobic coatings. While the heating wire solution is effective, small wide-angle mirrors are usually fixed with adhesive, which can easily cause them to detach during prolonged heating, increasing safety hazards for vehicles. Furthermore, the energy consumption of heating wires is high and the water removal speed is relatively slow, making it difficult to cope with heavy rain. On the other hand, the hydrophobic coating solution has poor durability. Over time, the coating effect gradually diminishes, and it cannot remove stubborn stains such as mud adhering to the mirror surface, ultimately leading to blurred rearview mirror images and affecting the driver's normal driving.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This application provides a vehicle rearview mirror assembly that can solve the problem of blurred rearview mirror images in rainy weather, which affects the driver's normal driving.

[0021] Reference Figure 1 This application discloses a vehicle rearview mirror assembly, which includes a rearview mirror housing 1 and a moving component 2. A lens 11 is mounted on the rearview mirror housing 1, and a magnifying lens 12 is disposed on the lens 11. The moving component 2 is disposed on the rearview mirror housing 1 and connected to the magnifying lens 12. The moving component 2 can drive the magnifying lens 12 to move along a preset path 21 on the lens 11. Furthermore, on a plane perpendicular to the lens 11, the projection of the preset path 21 is located within the projection range of the lens 11. The area traversed by the magnifying lens 12 along the preset path 21 covers the effective field of view of the lens 11. By moving the magnifying lens 12 on the lens 11 through the moving component 2, rainwater on the effective field of view of the lens 11 is wiped away, thereby maintaining a clear view for the driver even in rainy weather. Moreover, the convex lens structure of the magnifying lens 12 itself can significantly reduce the probability of rainwater remaining on the magnifying lens 12, thereby maintaining a clear field of view for the magnifying lens 12 itself. This solves the problem of blurred rearview mirror imaging in rainy weather that affects the driver's normal driving in related technologies.

[0022] Reference Figure 2 and Figure 3 In one embodiment of this application, a receiving space is provided on the rearview mirror housing 1, a moving component 2 is disposed within the receiving space, and a lens 11 is located between the moving component 2 and a magnifying lens 12. The moving component 2 and the magnifying lens 12 are connected by an adsorption component 3. By adding a receiving space to the rearview mirror housing 1, an internal installation space is provided for the moving component 2, allowing the moving component 2 to maintain the overall clean appearance of the rearview mirror housing 1 while moving the magnifying lens 12. Specifically, the adsorption component 3 includes a first magnetic element 31 and a second magnetic element 32. The first magnetic element 31 is disposed on the moving component 2, and the second magnetic element 32 is disposed on the magnifying lens 12. The first magnetic element 31 and the second magnetic element 32 are magnetically attracted to each other through the lens 11, thereby moving the magnifying lens 12 on the lens 11. Furthermore, since the magnifying lens 12 is attached to the lens 11 through the second magnetic element 32, rainwater on the lens 11 can be wiped off during the movement.

[0023] Furthermore, the moving component 2 includes a moving track and a moving slider. The moving track is set on the rearview mirror housing 1 and located within the receiving space to form a preset path 21. The moving slider is slidably mounted on the moving track, and the first magnetic element 31 is mounted on the moving slider. In actual use, the driver can directly move the magnifying glass 12 from the outside of the rearview mirror housing 1, thereby causing the magnifying glass 12 to move along the preset path 21 on the lens 11. In addition, considering the sealing risks that manual operation may bring, the outer surface of the moving slider's active area on the rearview mirror housing 1 is also covered with a flexible sealing film or equipped with a labyrinth-type sealing structure. This allows external magnetic force to penetrate and manual operation to be performed, while ensuring the sealing of the rearview mirror assembly and preventing moisture and dust from entering the receiving space and affecting the lens clarity. This manual drive method does not require additional motors and power lines, reducing system costs and failure rates, and can still be used when the vehicle is powered off, improving the reliability of the device. At the same time, the limitation of the preset path 21 ensures that the cleaning trajectory covers the key areas of the lens, avoiding cleaning dead spots caused by the randomness of manual operation.

[0024] In another embodiment of this application, the moving component 2 further includes a drive unit and a control system 4. The drive unit is mounted on the moving slider and is used to drive the moving slider to reciprocate along the moving track. The control system 4 is connected to the drive unit and is used to open and close the drive unit. The driver can open the drive unit through the control system 4, thereby causing the moving slider to move along the moving track, so as to move the magnifying glass 12 along the preset path 21 on the lens 11 to complete the wiping of rainwater on the lens 11. In actual working conditions, the control system 4 can be connected to the vehicle's own control center to further improve overall convenience.

[0025] In one embodiment of this application, the area of ​​the magnifying glass 12 is much smaller than the area of ​​the lens 11. The moving track is set along the width direction of the vehicle body and has at least one inflection point along the height direction of the vehicle body. The moving track is specifically set as a curved slide rail. The moving slider is slidably set on the moving track through a rolling pair. The driving component includes a reciprocating rotary motor, which is connected to the control system 4, and the output shaft of the reciprocating rotary motor is coaxially connected to the rolling pair. Turning the reciprocating rotary motor clockwise causes the moving slider to move along the preset path 21 on the lens 11. Turning the reciprocating rotary motor counterclockwise causes the moving slide rail to move in the opposite direction along the preset path 21, thereby realizing the reciprocating movement of the moving slider on the preset path 21. Furthermore, the moving track can be made of a metal material with magnetic adsorption properties, thereby ensuring the magnetic connection between the first magnetic component 31 and the moving track. When the driving component stops, the magnifying glass 12 can stop on the lens 11 through the magnetic adsorption between the first magnetic component 31 and the moving track, thereby allowing the driver to adjust the position of the magnifying glass 12 on the lens 11 by turning on the driving component, thereby optimizing its field of vision.

[0026] In another embodiment of this application, a moving track is set according to the shape of the rearview mirror. The moving track is made of a straight track and has multiple longitudinal folds along the height direction of the vehicle body so that when the first magnetic component 31 moves on the preset path 21, the magnifying glass 12 can cover the effective field of view on the lens 11. The driving component is a drive motor and a steering device to drive the first magnetic component 31 to move on the straight track. Both the drive motor and the steering device are connected to the control system 4. The steering device is used to control the moving slider to turn on the straight track. The control system 4 has a preset automatic dewatering program to control the driving component to move laterally or longitudinally on the moving track. Specifically, the lateral displacement of the first magnetic component 31 on the lens 11 along the width direction of the vehicle body is set as X, and the longitudinal displacement along the height direction of the vehicle body is set as Y. The lateral length of the actual moving track is set as Xmax, and the longitudinal distance is set as Ymax. When the lateral displacement of the moving slider on the moving track reaches Xmax, the control system 4 activates the steering device, so that the steering device drives the drive motor to rotate 90° vertically, so that the drive motor changes from sliding in the X direction to sliding in the Y direction. In the early stages of designing the moving track, the rearview length L and the rearview mirror width W are obtained, and the lateral length Xmax and longitudinal distance Ymax are designed based on the radius R of the magnifying glass 12. In other embodiments of this application, a current sensor can also be installed in the drive motor, eliminating the need for a position sensor. The operating current I is detected by the current sensor, and the stall current a of the motor is designed. When the operating current of the motor reaches the stall current a, it indicates that the moving slider has moved to the end of the lateral or longitudinal length of the moving track. At this time, the control system 4 activates the steering device, driving the moving slider to turn until it reaches the endpoint and completes the automatic water removal.

[0027] Furthermore, to facilitate the driver's removal of the magnifying glass 12 for cleaning, an adjusting member 121 for adjusting the distance between the magnifying glass 12 and the lens 11 is also provided on the magnifying glass 12. In one embodiment of this application, the adjusting member 121 includes a transmission rod and a transmission worm gear. One end of the transmission rod passes into the magnifying glass 12 and is provided with a transmission worm wheel, while the other end is provided with an adjusting knob. The transmission worm gear is arranged axially within the magnifying glass 12 and meshes with the transmission worm wheel. By rotating the adjusting knob, the transmission worm gear on the transmission rod can drive the transmission worm gear to extend towards the lens 11, pushing the magnifying glass 12 to move away from the lens 11, thereby adjusting the distance between the first magnetic element 31 and the second magnetic element 32, reducing the magnetic attraction between the moving component 2 and the magnifying glass 12, and making it easier for the driver to remove the magnifying glass 12 from the lens 11. When installing the magnifying glass 12, turn the adjustment knob in the opposite direction to retract the transmission worm gear into the magnifying glass 12. Then, attach the magnifying glass 12 to the lens 11 and magnetically attach it to the first magnetic component 31 on the moving assembly 2 to complete the installation of the magnifying glass 12.

[0028] To further enhance the water-removing and cleaning capabilities of the magnifying lens 12 on the surface of the lens 11, a wiper blade is provided at the end of the magnifying lens 12 facing the lens 11. The wiper blade abuts against the lens 11 to improve the cleaning force of the magnifying lens 12 as it moves on the lens 11. Specifically, the wiper blade extends along the width direction of the magnifying lens 12, and its length covers the entire effective wiping width of the contact area between the magnifying lens 12 and the lens 11. The wiper blade is made of a wear-resistant material with elastic recovery capabilities, such as rubber, silicone, or polyurethane. In terms of the connection structure, a mounting groove is formed on the end face of the magnifying lens 12 facing the lens 11. The wiper blade is embedded in the mounting groove and fixed by adhesive or interference fit, or it can be integrally injection molded with the magnifying lens 12.

[0029] The key is that the free end of the wiper blade has a pre-set interference fit with the surface of the lens 11, so that in the assembled state, the wiper blade undergoes a slight elastic deformation under pressure, thus tightly abutting against the surface of the lens 11. This elastic abutment ensures that when the magnifying lens 12 moves back and forth along the surface of the lens 11 under the drive assembly, the wiper blade can always adaptively conform to the surface of the lens 11, maintaining stable contact pressure even if the surface of the lens 11 has a slight curvature or vibrations caused by vehicle movement. During operation, when the drive mechanism moves the magnifying lens 12, the wiper blade uses the friction and elastic pressure between its edge and the surface of the lens 11 to effectively scrape away water film, raindrops, and dust impurities adhering to the surface of the lens 11, and pushes the dirt towards the edge of the lens. Compared to the direct hard contact between the magnifying glass 12 body and the lens 11, the wiper blade not only significantly improves the cleaning power of the magnifying glass 12 as it moves on the lens 11, avoiding the risk of scratches on the surface of the lens 11 caused by direct friction of hard materials, but also acts as a buffer medium to protect the lens coating and extend the service life of the rearview mirror assembly.

[0030] In another embodiment of this application, the movable component 2 can also be disposed on the rearview mirror housing 1. The movable component 2 specifically includes a slide rod, a movable block, and a telescopic connecting rod. The slide rod is disposed on the rearview mirror housing 1 at one end along either the length or width direction. The movable block is slidably disposed on the slide rod and slidably disposed along the length direction of the slide rod. One end of the telescopic connecting rod is disposed on the movable block, and the other end is connected to the magnifying glass 12. Preferably, the telescopic connecting rod contains an elastic reset element, such as a spring or damping buffer structure, to enable axial telescopic movement. This telescopic structure design is mainly used to compensate for distance fluctuations caused by changes in the curvature of the lens 11 surface or assembly errors during the movement of the magnifying glass 12, ensuring that the magnifying glass 12 always maintains a constant pressure against the surface of the lens 11. During operation, the driving component moves the movable block along the slide rod, which in turn pushes the magnifying glass 12 to reciprocate on the surface of the lens 11 via the telescopic connecting rod. By placing the movable component 2 on the rearview mirror housing 1 instead of the lens bracket, the internal space of the housing can be effectively utilized, reducing obstruction of the lens's field of vision. At the same time, the cooperation between the slide bar and the movable block provides higher movement stability, ensuring the smoothness of the cleaning process.

[0031] This application also proposes a vehicle equipped with the vehicle rearview mirror assembly provided in this application, so as to maintain a clear rearview mirror view for the driver even in rainy weather.
