Description

Technical Field

[0001] The present disclosure relates to an outside rearview mirror and a vehicle, belonging to the technical field of vehicles. Background Art

[0002] For the outside rearview mirror of a vehicle, its structure is not completely sealed, and there will be some gaps between the housing of the outside rearview mirror and the lens. Therefore, during the car wash process, the outside rearview mirror often gets water in. When the whole vehicle is thoroughly cleaned and wiped, the water accumulated inside the outside rearview mirror usually cannot be effectively drained. Currently, most designs of outside rearview mirrors lack a proper drainage mechanism. Either there are no dedicated drainage holes or channels, or even if there are, these drainage holes or channels are often too narrow or easily blocked by dirt and debris, resulting in the water not flowing out smoothly.

[0003] When the vehicle is in motion, the water stored inside the outside rearview mirror may drip out. These water droplets often drip onto the car door. For those car owners who have just had their vehicles meticulously washed, this is particularly annoying. The water droplets will leave ugly water stains on the car door, not only ruining the clean and shiny appearance of the vehicle but also requiring the car owner to spend extra effort to wipe it a second time. This not only wastes the car owner's time but also goes against the original intention of a thorough car wash, bringing unnecessary trouble during the post - car - wash maintenance process.

[0004] Therefore, how to effectively prevent water from entering the inside of the outside rearview mirror and how to drain the water when it enters the inside of the outside rearview mirror are problems that need to be solved urgently. Summary of the Invention

[0005] To solve the technical problems of traditional outside rearview mirrors, the present disclosure provides an outside rearview mirror and a vehicle having the outside rearview mirror, which can not only effectively prevent water from entering the inside of the outside rearview mirror to cope with scenarios such as car washing or rain, but also can reliably drain the water when it enters the inside of the outside rearview mirror.

[0006] Specifically, in a first aspect of the present disclosure, an outside rearview mirror is provided, which includes: a housing having an opening; a lens, the lens being installed in the internal space of the housing near the opening end of the housing to cover the opening of the housing; an angle adjustment part, the angle adjustment part being arranged in the internal space of the housing to adjust the tilt angle of the lens; and a translation driving part, the translation driving part being arranged in the internal space of the housing to drive the lens to translate back and forth.

[0007] According to the outside rearview mirror having the above configuration, in addition to the angle adjustment unit, a translation drive unit for driving the lens to translate back and forth is provided. Different from the traditional outside rearview mirror that can only adjust the tilt angles of the lens in the up, down, left, and right directions, the outside rearview mirror of the present disclosure can also adjust the position of the lens in the front-back direction, realizing multi-dimensional composite adjustment of the angle and position. Therefore, the user can operate the angle adjustment unit and the translation drive unit according to different scenarios to prevent water from entering the inside of the outside rearview mirror. For example, when washing the car, the user can operate the angle adjustment unit to return the lens to the factory position, and then operate the translation drive unit to move the lens backward so that the outer periphery of the lens closely adheres to the inner periphery of the housing. At this time, there is almost no gap between the outer periphery of the lens and the inner periphery of the housing, suppressing water from entering the inside of the outside rearview mirror through such a gap.

[0008] Preferably, in the outside rearview mirror of the first aspect, the angle adjustment unit includes a bracket and a first motor and a second motor provided on the bracket. One of the first motor and the second motor is used to adjust the tilt angle of the lens in the up-down direction, and the other is used to adjust the tilt angle of the lens in the left-right direction. And in the internal space of the housing, the translation drive unit is disposed at the rear side relative to the angle adjustment unit.

[0009] According to the outside rearview mirror having the above configuration, since the translation drive unit is integrally provided at the rear side of the angle adjustment unit, there is no mutual interference between the translation drive unit and the angle adjustment unit, and they can each reliably perform their functions.

[0010] Preferably, in the outside rearview mirror of the first aspect, the translation drive unit includes: a third motor; a first gear coaxially provided with the rotation output shaft of the third motor; and a drive shaft, the extending direction of the drive shaft is parallel to the central axis of the housing, one end is fixed to the rear surface of the bracket of the angle adjustment unit, and the other end is fixed to the inner surface of the housing. Wherein, the drive shaft includes a first threaded shaft on the angle adjustment unit side and a second threaded shaft on the housing side. The first threaded shaft is one of an internal threaded shaft and an external threaded shaft, and the second threaded shaft is the other of the internal threaded shaft and the external threaded shaft. At least a part of the outer peripheral surface of the external threaded shaft is formed with an external thread, at least a part of the internal threaded shaft is hollow and the inner peripheral surface is formed with an internal thread, and the external threaded shaft is threadedly engaged with the internal threaded shaft. And wherein, a second gear is formed on the outer peripheral surface of the second threaded shaft, and the second gear meshes with the first gear.

[0011] According to the outside rearview mirror having the above configuration, the translation drive unit can be realized by a simple and small structure, and the front-back translation of the lens can be simply achieved by converting the rotation of the motor into the telescoping of the drive shaft.

[0012] Preferably, in the exterior rearview mirror of the first aspect, the housing is provided with a groove at a position near the opening and on the rear side relative to the lens. The groove is circumferentially arranged on the inner peripheral surface of the housing, and the exterior rearview mirror further includes a sealing ring which is installed in the groove.

[0013] According to the exterior rearview mirror having the above structure, since a combination of a groove and a sealing ring is also provided in the housing, when the lens is translated in place, it can abut against the elastic sealing ring, and the sealing ring undergoes elastic deformation, applying an even contact pressure towards the lens, further reliably sealing the gap between the lens and the housing and preventing moisture from flowing into the housing. Moreover, since the sealing ring is embedded in the groove, the depth of the groove and the cross-section of the sealing ring form geometric interlocking, preventing the sealing ring from circumferentially slipping under a vibrating environment. The side wall of the groove forms a limit for the sealing ring, suppressing seal failure caused by thermal expansion and contraction, enabling the sealing ring to stably exhibit its sealing performance.

[0014] Preferably, in the exterior rearview mirror of the first aspect, it further includes: a blowing part which is arranged in the inner space of the housing and can blow out gas; and a gas delivery channel which is formed between the housing and the lens, and the gas blown out by the blowing part is blown towards the lens via the gas delivery channel.

[0015] According to the exterior rearview mirror having the above structure, since a blowing part capable of blowing out gas is also provided in the housing, water remaining in the housing can be blown out of the housing by controlling the blowing part, so that water will not continue to drip onto the car door after the car wash is completely finished. In addition, in rainy weather or the like, the rainwater can also quickly flow down from the lens due to the gas blown out by the blowing part and will not stay on the lens, keeping the field of view of the lens clear. In addition, when the lens fogs up due to too low temperature, gas can also be blown from the blowing part to the lens to defog the lens.

[0016] Preferably, in the exterior rearview mirror of the first aspect, the blowing part is a fan.

[0017] According to the exterior rearview mirror having the above structure, the blowing part can be configured with a simple and compact structure, which can ensure the reliability of blowing while not overly occupying the inner space of the housing, and has good operability.

[0018] Preferably, in the exterior rearview mirror of the first aspect, the gas delivery channel is arranged in the upper part, lower part or side part of the housing.

[0019] According to the exterior rearview mirror with the above structure, when the gas delivery channel is arranged in the upper part or the side part of the housing, the blown air flow can form an inclined angle and directly act on the lens surface, more effectively guiding the residual moisture to the outer edge of the housing, avoiding the retention or backflow of water droplets inside the housing, and optimizing the air flow guiding path. Moreover, when the gas delivery channel is close to the top area of the lens, the blown air flow can preferentially cover the upper edge area of the lens that is prone to fogging / icing, and eliminate fog or ice more quickly in a low-temperature environment, ensuring the driving vision. In addition, when the gas delivery channel is close to the lower area, water can be directly blown out along the arc of the lower edge of the housing, with high drainage efficiency.

[0020] Preferably, in the exterior rearview mirror of the first aspect, it further includes a switch part, and the switch part controls the opening and closing of the blowing part.

[0021] According to the exterior rearview mirror with the above structure, it is possible to control the opening and closing of the blowing part through the switch part at a specific time according to the user's expectation, realizing personalized control. Moreover, by designing the switch part, it is also possible to support, for example, the intelligent switching between the car wash mode and the daily mode. For example, when the system determines through sensors, cameras, etc. that the vehicle is in a car wash scenario, the switch part is automatically turned on to activate the blowing part for pre-drying to prevent high-pressure water from remaining in the housing; when the system determines that the vehicle is driving in the rain, the switch part can also be automatically turned on to achieve the aforementioned water removal and defogging, and keep the lens clear through continuous air flow and heating elements.

[0022] Preferably, in the exterior rearview mirror of the first aspect, the switch part is a wired control and / or wireless control switch.

[0023] According to the exterior rearview mirror with the above structure, the switch part can be configured for wired or wireless control. For example, the wired control switch can be integrated into the control panel of the driver's seat in the vehicle, facilitating the driver to directly activate the blowing part for drying operation after car washing, avoiding getting out of the car for manual intervention; the wireless control switch (such as voice commands of the vehicle system or remote operation through a mobile phone APP) can start the blowing and draining function in advance when not in the car after car washing, improving the flexibility of use. Moreover, the dual-control mode can also meet different user habits. Traditional drivers prefer the immediate feedback of physical buttons, while young users are more inclined to remote operation through a mobile phone APP, both of which can be satisfied.

[0024] The second aspect of the present disclosure provides a vehicle having the exterior rearview mirror according to the first aspect.

[0025] The vehicle of the second aspect of the present disclosure can also achieve the same technical effects as the first aspect.

[0026] Next, the specific technical solutions of the present disclosure will be described with reference to the accompanying drawings, and the details of the present disclosure will be more easily understood. Description of the Drawings

[0048] Hereinafter, the technical solutions of the present invention will be described more clearly by describing the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0049] It should be noted that the drawings of the present invention are merely schematic diagrams simply shown for clearly showing the parts related to the solution of the present invention, and do not show some non-essential parts that may exist. Therefore, these drawings should not be construed as a limitation to the present invention, and they may be different from the actual structure during use. Additionally, it should also be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., which may represent directions or positions in the following description, are for the purpose of convenience of description and are not restrictive. Similarly, for the sake of clarity and conciseness, the descriptions of well-known functions and structures are omitted in the following description.

[0050] Figure 1 is a schematic plan view of the outside rearview mirror 1 of an embodiment of the present disclosure; Figure 2 is a schematic plan view of the outside rearview mirror 1 of an embodiment of the present disclosure, only showing the fan 22 inside. The outside rearview mirror 1 of this embodiment can not only effectively prevent water from entering the inside of the outside rearview mirror 1, so as to cope with the scenarios of car washing or raining, but also can reliably drain the water when the water enters the inside of the outside rearview mirror 1.

[0051] As Figure 1 shown, the outside rearview mirror 1 of this embodiment includes: a housing 10 having an opening; a lens 25, the lens 25 is installed in the internal space of the housing 10 near the opening end of the housing 10 to cover the opening of the housing 10; an angle adjustment part 11, the angle adjustment part 11 is arranged in the internal space of the housing 10 to adjust the tilt angle of the lens 25; and a translation drive part 12, the translation drive part 12 is arranged in the internal space of the housing 10 to drive the lens 25 to translate back and forth.

[0052] The angle adjustment part 11 in this embodiment can adopt a well-known angle adjustment mechanism for outside rearview mirrors, so Figure 1 only shows its approximate position in a box, and does not show its specific composition. Specifically, the angle adjustment part 11 may include a bracket and a first motor and a second motor arranged on the bracket. One of the first motor and the second motor is used to adjust the tilt angle of the lens 25 in the up and down direction, and the other is used to adjust the tilt angle of the lens 25 in the left and right direction.

[0053] As Figure 1As shown, in the internal space of the housing 10, the translation drive unit 12 is arranged at the rear side relative to the angle adjustment unit 12. By staggering the angle adjustment unit 11 and the translation drive unit 12, the translation drive unit 12 and the angle adjustment unit 11 will not interfere with each other, and each can reliably perform its function. The angle adjustment unit 11 can independently adjust the tilt angle of the lens 25 without being affected by the translation drive unit 12. Moreover, when the translation drive unit 12 is working, the angle adjustment unit 11 and the lens 25 can be translated as a whole in the forward and backward directions without being affected by the angle adjustment unit 11.

[0054] It can be seen that according to the exterior rearview mirror 1 of the present embodiment, in addition to the conventional angle adjustment unit 11, a translation drive unit 12 for driving the lens 25 to translate forward and backward is also provided. Unlike the conventional exterior rearview mirror that can only adjust the tilt angle of the lens up, down, left, and right, the exterior rearview mirror 1 of the present embodiment can also adjust the position of the lens 25 in the front and back directions, realizing multi-dimensional composite adjustment of the angle and position. Therefore, the user can suppress water from entering the interior of the exterior rearview mirror by operating the angle adjustment unit 11 and the translation drive unit 12 according to different scenarios. For example, when washing the car, the user can restore the lens 25 to the factory position by operating the angle adjustment unit 11, and then operate the translation drive unit 12 to translate the lens 25 backward so as to enter a state where the outer periphery of the lens 25 is close to the inner periphery of the housing 10. At this time, there is almost no gap between the outer periphery of the lens 25 and the inner periphery of the housing 10, which suppresses water from entering the interior of the exterior rearview mirror 1 through such a gap.

[0055] Next, we will refer to Figure 1 The structure of the translation drive unit 12 in the exterior rearview mirror 1 of this embodiment is described below. Figure 1 As shown, the translation driving unit 12 of the exterior rearview mirror 1 includes: a third motor 13; a first gear 14, which is coaxially arranged with the rotation output shaft of the third motor 13; and a driving shaft 15, the extension direction of which is parallel to the central axis of the housing 10, for example, along the central axis. One end of the driving shaft 15 is fixed to the rear surface of the bracket of the angle adjustment unit 11, and the other end is fixed to the inner surface of the housing 10, for example, through a bearing 24.

[0056] The drive shaft 15 is as Figure 1As shown, it includes an external thread shaft 16 on the side of the angle adjustment part 11 and an internal thread shaft 17 on the side of the housing 10. External threads are formed on at least a part of the outer peripheral surface of the external thread shaft 16. Specifically, external threads are formed at least at one end close to the internal thread shaft. At least a part of the internal thread shaft 16, specifically one end close to the external thread shaft, is of a hollow shape, and internal threads are formed on the inner peripheral surface of the hollow shape. The external thread shaft 16 and the internal thread shaft 17 are thread - fitted to each other through a thread 19 composed of the external thread and the internal thread, enabling the external thread shaft 16 to be thread - fitted to the internal thread shaft 17. A second gear 18 is formed on the outer peripheral surface of the internal thread shaft 17, and the second gear 18 meshes with the first gear 14.

[0057] Through the above - mentioned translation driving part 12, when the front - rear translation of the lens 25 is required, the third motor 13 is driven to operate and its rotating shaft rotates forward and backward. Since the rotating shaft of the third motor 13 is coaxially fixed with the first gear 14, the first gear 14 also rotates forward and backward accordingly. The first gear 14 meshes with the second gear 18, driving the second gear 18 to rotate forward and backward, and then driving the internal thread shaft 17 to rotate forward and backward. At this time, since the internal thread shaft 17 is thread - connected to the external thread shaft 16, with the forward and backward rotation of the internal thread shaft 17, the external thread shaft 16 axially moves correspondingly, that is, moves forward and backward. Therefore, the lens 25 can be driven to move forward and backward, realizing the adjustment of the front - rear position of the lens 25.

[0058] As Figure 1 shown, in the vehicle exterior rearview mirror 1 of this embodiment, the housing 10 is further provided with a groove 20 at a position close to the opening and located at the rear side relative to the lens 25. The groove 20 is arranged circumferentially on the inner peripheral surface of the housing 10. The vehicle exterior rearview mirror 1 further includes a sealing ring 21, and the sealing ring 21 is installed in the groove 20. The sealing ring 21 is made of an elastic material, and its cross - section can be the circular shape shown in the figure, or other shapes such as square or oval.

[0059] In the vehicle exterior rearview mirror 1 of this embodiment, due to the combination of the groove 20 and the sealing ring 21 provided in the housing 10, when the lens 25 is translated in place, it can abut against the elastic sealing ring 21. The sealing ring 21 undergoes elastic deformation and exerts an even contact pressure towards the lens 25, further reliably sealing the gap between the lens 25 and the housing 10 and preventing moisture from flowing into the housing 10. Moreover, since the sealing ring 21 is embedded in the groove 20, the groove depth and the cross - section of the sealing ring form geometric interlocking, preventing the sealing ring 21 from circumferentially slipping in a vibrating environment. The side wall of the groove forms a limit for the sealing ring 21, suppressing the sealing failure caused by thermal expansion and contraction, enabling the sealing ring 21 to stably perform the sealing function.

[0060] As Figure 1 and Figure 2As shown in the figure, the outside rearview mirror 1 of this embodiment further includes: a fan 22 serving as a blowing part, which is arranged in the internal space of the housing 10 and can blow out gas; and a gas delivery channel 23 formed between the housing 10 and the lens 25, and the gas blown out by the fan 22 is blown towards the lens 25 via the gas delivery channel 23.

[0061] The gas delivery channel 23 can be arranged at the upper part, lower part or side part of the housing 10. The position and / or opening degree of the gas delivery channel 23 can be adjusted by the angle adjustment part 11 and the translation drive part 12.

[0062] With the outside rearview mirror 1 configured as above in this embodiment, since there is also a fan 22 capable of blowing out gas arranged in the housing 10, therefore, the water remaining in the housing 10 can be blown out of the housing 10 by controlling the fan 22, so that water will not continue to drip onto the car door after the car wash is completed. In addition, in rainy weather, etc., the rainwater can also be quickly drained from the lens 25 by the gas blown out by the fan 22 and will not stay on the lens 25, keeping the view of the lens 25 clear. In addition, when the lens 25 fogs up due to too low temperature, etc., gas can also be blown from the fan 24 to the lens 25 to defog the lens 25.

[0063] In addition, since the gas delivery channel 23 of the outside rearview mirror 1 is arranged at the upper part or side part of the housing 10, the blown air flow can form an inclined angle and directly act on the lens surface, more effectively guiding the residual moisture to the outer edge of the housing 10, avoiding the retention or backflow of water droplets inside the housing, and optimizing the air flow guiding path. Moreover, when the gas delivery channel 23 is close to the top area of the lens 25, the blown air flow can preferentially cover the upper edge area of the lens 25 that is prone to fogging / icing, and can more quickly eliminate fog or ice layers in a low-temperature environment, ensuring the driving view. In addition, when the gas delivery channel 23 is close to the lower area, the water can be directly blown out along the arc of the lower edge of the housing 10, with high drainage efficiency. Moreover, since this embodiment is also provided with a translation drive part 12, therefore, the fan 22 cooperates with the drainage gap opened by the translation drive part 12 to achieve efficient drainage of the accumulated water inside the housing 10, reducing the water storage time and residual amount.

[0064] In addition, in addition to blowing out the car wash water from the housing 10 of the outside rearview mirror 1 in advance in the car wash scenario to ensure the car wash effect and maintain a clean appearance. For example, in cold weather or rainy and snowy weather, the fan 22 of the outside rearview mirror 1 can also work in cooperation with the lens heating element to accelerate the dissipation of rain and snow and the melting of the ice on the lens. The continuous air flow can blow away the raindrops on the lens surface and improve the rearview clarity in bad weather.

[0065] The outside rearview mirror of this embodiment further includes a switch unit that controls the opening and closing of the fan 22. The switch unit can be either wired control or wireless control, or can be either wired control or wireless control.

[0066] By providing the switch unit, it is possible to control the opening and closing of the fan 22 through the switch unit at a specific time as desired, achieving personalized control. Moreover, by designing the switch unit, it is also possible to support, for example, the intelligent switching between the car wash mode and the daily mode. For example, when the system determines through sensors, cameras, etc. that the vehicle is in a car wash scenario, the switch unit is automatically turned on to activate the fan 22 for pre-drying to prevent high-pressure water from remaining in the housing; when the system determines that the vehicle is driving in the rain, the switch unit can also be automatically turned on to achieve the aforementioned water removal and defogging, and the lens is kept clear by continuous airflow in cooperation with the heating element.

[0067] When the switch unit is configured for wired control, for example, the wired control switch can be integrated into the control panel of the driver's seat in the vehicle, facilitating the driver to directly start the blowing unit for drying operation after car washing and avoiding manual intervention when getting out of the car. When the switch unit is configured for wireless control, for example, the wireless control switch (such as voice commands of the in-vehicle system or remote operation of the mobile phone APP) can start the blowing and drainage function in advance when not getting into the car after car washing, improving the usage flexibility. Moreover, when the switch unit is configured for both wired and wireless dual control, the dual control mode can meet different user habits. Traditional drivers prefer the immediate feedback of physical buttons, and young users are more inclined to remote operation through the mobile phone APP, both of which can be satisfied.

[0068] The outside rearview mirror 1 of this embodiment has been described above in conjunction with the drawings. It can not only effectively prevent water from entering the inside of the outside rearview mirror 1, thus coping with car wash or rainy scenarios, but also reliably drain the water when water enters the inside of the outside rearview mirror 1.

[0069] In addition, it should be noted that in this embodiment, for the drive shaft, the example of an external thread shaft being provided on the angle adjustment part side and an internal thread shaft being provided on the housing side has been described. However, this is not restrictive. For the drive shaft, it can also be that the internal thread shaft is provided on the angle adjustment part side and the external thread shaft is provided on the housing side.

[0070] The above specific embodiments do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
