[0027] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0028] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0029] As mentioned above, frameless exterior rearview mirrors have been widely used in the automotive industry due to their aesthetically pleasing appearance and significant advantages in reducing wind resistance. However, because frameless exterior rearview mirrors lack the frame of traditional rearview mirrors, the mirror surface lacks physical protection in rainy weather. Rainwater easily adheres to the mirror surface, forming water droplets or even continuous streams, affecting the driver's visibility. This is especially true when driving at high speeds in the rain or under extreme rainfall conditions, often requiring drivers to frequently wipe the mirror surface to restore their vision.

[0030] In view of this, such as Figures 1 to 5 As shown, according to a first aspect of this disclosure, an exterior rearview mirror 100 is provided, including a mirror base assembly 1, a first lens 2, and a drive member 3. The mirror base assembly 1 includes a mirror frame 11, a first receiving cavity 12 is provided inside the mirror frame 11, and a first opening 13 communicating with the first receiving cavity 12 is provided on the mirror frame 11. The first lens 2 is located in the receiving cavity, and the first opening 13 exposes the first lens 2. The drive member 3 is installed on the mirror base assembly 1, and the drive member 3 is connected to the side of the first lens 2 away from the first opening 13, and is used to drive the first lens 2 to move toward or away from the first opening 13.

[0031] It should be noted that the aforementioned exterior rearview mirror 100 can be applied to any device suitable for setting the exterior rearview mirror 100. For example, the exterior rearview mirror 100 can be applied to a vehicle, allowing the driver to observe the surrounding environment through the exterior rearview mirror 100, thereby achieving safe driving. Alternatively, the exterior rearview mirror 100 can also be applied to construction machinery and monitoring systems, etc. This disclosure does not limit it in this regard.

[0032] In the exterior rearview mirror 100 provided in this disclosure, since the mirror mount assembly 1 of the exterior rearview mirror 100 is provided with a drive member 3 connected to the first lens 2, and the drive member 3 is used to drive the first lens 2 to move toward or away from the first opening 13, the exterior rearview mirror 100 can have different usage states according to different usage scenarios.

[0033] For example, under rainless conditions, the first lens 2 can be moved towards the first opening 13 near the mirror frame 11 under the driving action of the driving member 3, which allows the exterior rearview mirror 100 to be frameless. The exterior rearview mirror 100 with a frameless structure can have high aesthetics and low wind resistance, which can meet the user's aesthetic requirements and help reduce the energy consumption and wind noise of vehicles and other devices that use the exterior rearview mirror 100.

[0034] Furthermore, in rainy weather, the first lens 2 can be moved away from the first opening 13 of the mirror frame 11 by the drive component 3, which allows the exterior rearview mirror 100 to be constructed as a framed rearview mirror. In this way, the upper mirror frame 11, which is constructed as a framed rearview mirror, can protect the first lens 2 from rain, thereby preventing rainwater from falling directly onto the unobstructed first mirror surface and forming water droplets or even continuous water flow on the first mirror surface, which would affect the driver's visibility and improve driving safety.

[0035] It is easy to see that, compared with the related technologies, which involve setting a heating device inside the exterior rearview mirror 100 and using the heating device to clean rainwater from the exterior rearview mirror 100, the exterior rearview mirror 100 provided in this disclosure only needs to drive the first lens 2 to move via the driving component 3 to achieve rain protection. It responds quickly and avoids the large energy consumption caused by continuous heating of the heating device, which is beneficial for energy saving.

[0036] Compared to related technologies where a hydrophobic agent is coated on the lens of the exterior rearview mirror 100, the hydrophobic agent tends to degrade after a period of use, and uneven coating can easily lead to visual interference. In contrast, the exterior rearview mirror 100 provided in this disclosure does not require a hydrophobic agent to be coated on the first lens 2, has a longer rainproof effect, and is less likely to cause visual interference.

[0037] Furthermore, compared to the related technologies where a rainproof film is applied to the lens of the exterior rearview mirror 100, the exterior rearview mirror 100 provided in this disclosure does not require a rainproof film to be applied to the first lens 2, which can effectively avoid the risk of visual interference caused by applying a rainproof film to the first lens 2.

[0038] Furthermore, compared to the implementation method of adding rain guards to the exterior rearview mirror 100 in related technologies, the exterior rearview mirror 100 provided in this disclosure can achieve rain protection without adding rain guards, and can be constructed as a frameless rearview mirror when there is no rain. It has the advantages of simple structure, high aesthetics and low wind resistance.

[0039] In summary, through the above technical solutions, the exterior rearview mirror 100 provided in this application can be frameless, and the exterior rearview mirror 100 can have high aesthetics and low wind resistance, which can improve the user experience and help reduce the energy consumption and wind noise of vehicles and other devices using the exterior rearview mirror 100. In addition, in rainy weather, the exterior rearview mirror 100 can also have a framed state (or a thin framed state). In this way, the frame 11 located on the lens (such as the first lens 2) can also block rainwater and prevent rainwater from interfering with the viewing angle of the first lens 2.

[0040] In addition, the exterior rearview mirror 100 provided in this disclosure also has the advantages of rapid rain protection response, low energy consumption, long rain protection life, and clear image quality.

[0041] It should be noted that the exterior rearview mirror 100 provided in this disclosure is not limited to the above-mentioned method of driving the first lens 2 to move by the driving component 3. The first lens 2 can also be moved by the operator (e.g., the driver) to make the first lens 2 be in different positions within the mirror frame 11, thereby allowing the first lens 2 to switch between different states.

[0042] Optionally, such as Figures 2 to 5 As shown, the first lens 2 has a first position and a second position. In the first position, the first lens 2 and the first opening 13 have a first distance D1. In the second position, the first lens 2 and the first opening 13 have a second distance D2. The first distance D1 satisfies: 0mm≤D1≤2mm, and the second distance D2 satisfies: 2mm<D2≤4mm.

[0043] First, it needs to be explained that the first distance D or the second distance D2 between the first lens 2 and the first opening 13 means that the distance between any point on the first lens 2 and the first opening 13 satisfies the first distance or the second distance.

[0044] Since in the first position, the first distance D1 between the first lens 2 and the first opening 13 satisfies: 0mm≤D1≤2mm, when the first lens 2 is in the first position, the distance between the first lens 2 and the first opening 13 is short, or at least partially overlaps. The first lens 2, which is short in distance from the first opening 13 or at least partially overlaps, is less obstructed by the frame 11, and can be constructed as a frameless exterior rearview mirror 100, which can have higher aesthetics and lower wind resistance, which is beneficial to improving the user experience and reducing energy consumption and wind resistance.

[0045] Furthermore, since in the second position, the second distance D2 between the first lens 2 and the first opening 13 satisfies: 2mm < D2 ≤ 4mm, when the first lens 2 is in the second position, there can be a large distance between the first lens 2 and the first opening 13. The first lens 2, which is at a large distance from the first opening 13, is more blocked by the frame 11, resulting in better rain protection and less susceptibility to rainwater adhesion, thus providing higher visual clarity in rainy weather.

[0046] In the exterior rearview mirror 100 provided in this disclosure, the drive unit 3 and the first lens 2 can be connected in any appropriate manner. For example, the first lens 2 can be directly attached to the drive part of the drive unit 3 (such as the telescopic rod 32 of the telescopic motor 31 mentioned below). The first lens 2 can also be connected to the drive unit 3 through other structures. This disclosure does not limit this.

[0047] As one embodiment of this disclosure, such as Figure 1 as well as Figure 4 and Figure 5 As shown, the exterior rearview mirror 100 also includes a mirror holder 4, which is located in the first receiving cavity 12 and is attached to the side of the first lens 2 opposite to the first opening 13. The drive unit 3 is connected to the mirror holder 4.

[0048] In other words, the drive unit 3 is connected to the first lens 2 through the lens holder 4. The connection between the first lens 2 and the drive unit 3 is relatively reliable and is not easy to fall off the drive unit 3.

[0049] In addition, it can effectively prevent the driving component 3 from being directly connected to the first lens 2, which could easily damage the fragile first lens 2 when the driving component 3 moves.

[0050] To limit the movement of the first lens 2, optionally, such as Figure 1 As shown, a limiting boss 14 is provided on the cavity wall of the first receiving cavity 12. The limiting boss 14 can abut against the lens holder 4 as the first lens 2 moves in a direction away from the first opening 13.

[0051] By providing a limiting protrusion 14 on the cavity wall of the first receiving cavity 12 for abutting against the mirror holder 4, the limiting protrusion 14 can limit the first lens 2 as it moves away from the first opening 13, thus preventing the first lens 2 from moving too far and colliding with other components inside the exterior rearview mirror 100, which would easily damage other components and / or the first lens 2 inside the exterior rearview mirror 100, thereby improving the service life of the exterior rearview mirror 100.

[0052] Optionally, such as Figures 1 to 5 As shown, the lens mount assembly 1 also includes a decorative cover 15, which is located on the side of the lens frame 11 opposite to the first opening 13 and connected to the lens frame 11. The drive member 3 is installed between the lens frame 11 and the decorative cover 15. A through hole 16 communicating with the first receiving cavity 12 is formed on the lens frame 11. A part of the drive member 3 passes through the through hole 16 and is connected to the first lens 2.

[0053] By setting a decorative cover 15 on the side of the mirror frame 11 away from the opening, and placing the drive component 3 between the mirror frame 11 and the decorative cover 15, the decorative cover 15 can cover the drive component 3, effectively avoiding the situation where the exterior rearview mirror 100 is poorly aesthetically pleasing due to the drive component 3 being exposed.

[0054] Furthermore, the decorative cover 15 and the frame 11 can also protect the drive component 3, effectively preventing the drive component 3 from being exposed to the elements and being damaged by wind and sun, and / or by collisions with other objects.

[0055] Furthermore, since the frame 11 has a through hole 16 that communicates with the first receiving cavity 12, and the driving member 3 passes through the through hole 16 and is connected to the first lens 2, the frame 11 will not interfere with the driving member 3, effectively avoiding the situation where the frame 11 interferes with the driving member 3 and the driving member 3 cannot drive the first lens 2 to move normally.

[0056] To facilitate the installation of driver 3, optionally, such as Figure 1 , Figure 4 and Figure 5 As shown, the above-mentioned mirror mount assembly 1 may also include a mounting plate 17, which is located between the mirror frame 11 and the decorative cover 15 and connected to the decorative cover 15. A mounting groove 18 is provided on the side of the mounting plate 17 near the mirror frame 11, and the driving component 3 is installed in the mounting groove 18.

[0057] The drive unit 3, which is connected to the decorative cover 15 via the mounting plate 17, is reliably installed inside the exterior rearview mirror 100, is not easily shaken, and can reliably drive the first lens 2 to move.

[0058] In addition, the mounting slot 18 provided on the mounting plate 17 can facilitate the installation of the drive component 3 on the mounting plate 17. There is no need to repeatedly measure the installation position of the drive component 3. Simply put the drive component 3 into the mounting slot 18 to achieve the pre-positioning of the drive component 3 on the mounting plate 17.

[0059] In the exterior rearview mirror 100 provided in this disclosure, the driving member 3 can be any driving member 3 suitable for being disposed in the exterior rearview mirror 100, and this disclosure does not limit it. As one embodiment of this disclosure, such as Figure 1 , Figure 4 and Figure 5 As shown, the driving component 3 includes a telescopic motor 31, and the telescopic rod 32 of the telescopic motor 31 is connected to the middle part of the first lens 2.

[0060] Thus, by controlling the telescopic motor 31, the telescopic rod 32 of the telescopic motor 31 can be extended outward (i.e. towards the direction close to the first opening 13), or the telescopic rod 32 of the telescopic motor 31 can be retracted inward (i.e. towards the direction away from the first opening 13), thereby driving the first lens 2 to move. For example, the first lens 2 can be driven to the first position or the second position mentioned above, so that the exterior rearview mirror 100 can have a high aesthetic appeal and low wind resistance, or make the exterior rearview mirror 100 less susceptible to rainwater adhesion, i.e., it can have a rainproof effect.

[0061] As another embodiment of this disclosure, the drive component 3 may also be constructed as a linear motor, a hydraulic drive component, or a pneumatic drive component, etc., and this disclosure does not limit it in this way.

[0062] To provide the exterior rearview mirror 100 with a wider field of view, optionally, such as Figures 1 to 3 As shown, the exterior rearview mirror 100 also includes a second lens 5, and the mirror mount assembly 1 also has a second receiving cavity 19 and a second opening 20 communicating with the second receiving cavity 19. The second receiving cavity 19 is arranged side by side with the first receiving cavity 12. The area of ​​the first lens 2 is larger than the area of ​​the second lens 5, and the focal length of the first lens 2 is larger than the focal length of the second lens 5.

[0063] By setting a second lens 5 parallel to the first lens 2 on the mirror mount assembly 1, and making the focal length of the first lens 2 greater than that of the second lens 5, the first lens 2 can have a higher visual clarity, and the second lens 5 can have a larger visual range. In this way, the first lens 2 and the second lens 5 work together to enable the exterior rearview mirror 100 to have both a large visual range and good clarity, which can meet the usage requirements of devices such as vehicles, and further improve the user experience.

[0064] It should be noted that this disclosure does not limit the installation method of the second lens 5 on the lens mount assembly 1. The second lens 5 can be fixedly installed on the lens mount assembly 1, or the second lens 5 can be movably installed on the lens mount assembly 1 in the manner of, for example, the first lens 2. This disclosure does not limit this.

[0065] This disclosure does not limit the specific type of the first lens 2 and the second lens 5, as long as the focal length of the first lens 2 is greater than the focal length of the second lens 5, and the first lens 2 and the second lens 5 cooperate to enable the exterior rearview mirror 100 to have a large field of view as a whole.

[0066] As one embodiment of this disclosure, the first lens 2 includes any one of a convex mirror, a plane mirror, and a Fresnel mirror, and / or the second lens 5 includes any one of a convex mirror, a plane mirror, and a Fresnel mirror.

[0067] By appropriately selecting the types of the first lens 2 and the second lens 5, both the first lens 2 and the second lens 5 can have a large field of view and also maintain good clarity.

[0068] Optionally, such as Figures 1 to 3 As shown, the mirror mount assembly 1 may also include a turn signal 21 and a lamp cover 22. The turn signal 21 is mounted on the decorative cover 15, and the lamp cover 22 covers the turn signal 21 and is connected to the decorative cover 15.

[0069] By providing a turn signal 21 on the exterior rearview mirror 100, when the vehicle lighting device using the exterior rearview mirror 100 provided in this disclosure is rotating, the turn signal 21 can serve as a warning to surrounding vehicles and pedestrians, which helps to further improve the safety of vehicles and other devices using the exterior rearview mirror 100 assembly.

[0070] According to a second aspect of this disclosure, a vehicle is provided, including the exterior rearview mirror 100 as described above.

[0071] The vehicle has all the beneficial effects of the aforementioned exterior rearview mirror 100, which will not be repeated here.

[0072] By installing the exterior rearview mirror 100 as described above on the vehicle, the vehicle can have a high aesthetic appeal and low wind resistance in rainless conditions, which can meet the user's aesthetic requirements and help reduce the energy consumption and wind noise of vehicles and other devices that have applied the exterior rearview mirror 100.

[0073] In addition, the vehicle also has good visibility in rainy weather, which helps improve the vehicle's safety.

[0074] It should be noted that this disclosure does not limit the specific type of vehicle mentioned above. The vehicle can be any vehicle suitable for installing the exterior rearview mirror 100 provided in this disclosure. For example, the vehicle can be a passenger car, such as a sedan or SUV, or a commercial vehicle, such as a truck, van, or special vehicle (such as a water tanker or garbage truck). The vehicle can be a traditional energy vehicle, such as a fuel vehicle, or a new energy vehicle. This disclosure does not limit the type of vehicle.

[0075] To control the operation of the drive unit 3, the vehicle may optionally include an on-board control unit (VCU) to which the drive unit 3 is electrically connected, wherein the vehicle also includes a rain sensor electrically connected to the VCU; and / or, the vehicle also includes a control panel electrically connected to the VCU; and / or, the vehicle also includes control buttons electrically connected to the VCU.

[0076] By installing an on-board control unit on the vehicle, along with a rain sensor, control module, and control buttons electrically connected to the on-board control unit, the first lens 2 of the vehicle's exterior rearview mirror 100 can be moved within the mirror mount assembly 1 under different weather conditions (e.g., rainy days) or by the user's active operation, thereby achieving rain protection or better aesthetics and lower wind resistance, thus meeting different user needs.

[0077] Taking a vehicle implementation including an onboard control unit, a rain sensor, a control module, and control buttons as an example, the operation of the vehicle's exterior rearview mirror 100 is explained as follows: The vehicle's exterior rearview mirror 100 automatic mode: During vehicle operation, the rain sensor monitors and collects rainfall data in real time. When the rain sensor detects rain, it generates a rain signal and transmits it to the vehicle control unit. After processing the rain signal, the vehicle control unit determines whether the rain signal reaches a preset value. If the rain signal reaches the preset value, the vehicle control unit automatically sends a state switching command to the drive component 3. Upon receiving the state switching command, the drive component 3 begins to move the first lens 2 to the second position, that is, the exterior rearview mirror 100 is in the framed state (or thin framed state), thereby achieving rain protection for the first lens 2. At the same time, the drive component 3 returns an action execution feedback signal to the vehicle control unit. If the rain signal does not reach the preset value, the vehicle control unit will not issue a state switching command.

[0078] For the manual mode of the vehicle's exterior rearview mirror 100: When the driver feels that the rain is heavy and affects visibility, or when the driver wants to switch the state of the exterior rearview mirror 100, the driver can send a control command to the vehicle control unit by operating the control module or control button. After receiving the control command, the vehicle control unit will send a manual switching command to the drive unit 3. After receiving the manual switching command, the drive unit 3 will start to move, driving the first lens 2 to move from the first position to the second position, that is, the exterior rearview mirror 100 is in the framed state (or thin framed state), thereby achieving rain protection for the first lens 2. At the same time, the drive unit 3 will return an action execution feedback signal to the vehicle control unit.

[0079] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0080] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0081] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
