Description

Technical Field

[0001] This utility model relates to the field of automotive rearview mirror technology, and in particular to a rearview mirror assembly. Background Technology

[0002] Car rearview mirrors are used by drivers to observe the situation behind the vehicle, enabling them to check the rear of the vehicle when turning and changing lanes, thus ensuring driving safety. However, when driving in rainy or foggy weather, the rearview mirrors become blurry due to rain or fog adhering to the mirror surface, which is detrimental to the driver's safe driving.

[0003] In existing technologies, most methods for removing fog from rearview mirrors involve heating the mirror by installing a heating element on the back of the mirror. However, this heating element is slow to remove rainwater from the mirror, requiring manual wiping. On rainy days, manually wiping the rearview mirror often results in getting wet, or it is inconvenient for the driver to wipe the passenger side mirror. This makes it difficult to clean the rainwater or fog from the rearview mirror, affecting driving safety. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a rearview mirror assembly, which aims to solve the technical problem that the inconvenience of cleaning rainwater and fog on the rearview mirror affects driving safety.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A rearview mirror assembly includes a mirror base and a rearview mirror.

Detailed Implementation

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0015] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] See Figures 1 to 3This utility model provides a rearview mirror assembly, mainly used for installation on automobiles. It includes a mirror base connected to the automobile at one end and a rearview mirror disposed at the other end of the mirror base. The rearview mirror includes a housing 1, within which a first cavity 11 is provided, and a second cavity 12 is provided near the mirror base. The first cavity 11 has a one-sided opening structure. From the outside to the inside of the first cavity 11, a reflector 2, an angle adjustment assembly 3, and a drive assembly 4 are sequentially arranged. A fan assembly 5 is provided in the second cavity 12, including a fan 51 and a heating assembly 52. ​​An air outlet 13 is provided between the first cavity 11 and the second cavity 12. Hot air is generated by the combined action of the fan 51 and the heating assembly 52. ​​The hot air generated in the second cavity 12 by the fan assembly 5 enters the first cavity 11 through the air outlet 13, thereby heating the reflector 2 and achieving the defogging function of the reflector 2. When there is rainwater on the reflector 2, the angle adjustment component 3 can be rotated by the drive component 4, which will simultaneously drive the reflector 2 to rotate, so that the end of the reflector 2 near the air outlet 13 rotates into the housing 1, thereby directing the hot air generated by the fan component 5 to the front side of the reflector 2, and quickly cleaning and drying the rainwater on the reflector 2.

[0018] Furthermore, the angle adjustment component 3 includes a housing 31, with a second support rod 33 and a first support rod 32 respectively provided at the upper and lower ends of the housing 31. The second support rod 33 and the first support rod 32 are cylindrical and coaxially arranged. One end of the first support rod 32 is fixedly connected to the lower side of the housing 31, and the other end is rotatably connected to the inner wall of the housing 1. One end of the second support rod 33 is fixedly connected to the upper side of the housing 31, and the other end is rotatably connected to the inner wall of the housing 1. It can be understood that the angle adjustment component 3 is fixedly installed inside the housing 1 through the second support rod 33 and the first support rod 32. A reflector 2 is fixed to one side of the front end of the angle adjustment component 3, wherein the shape of the reflector 2 is the same as the shape of the opening end of the housing 1. The reflector 2 achieves up, down, left, and right angle adjustment through the angle adjustment component 3. The angle adjustment component 3 is prior art and will not be described in detail here. It is also worth mentioning that since the reflector 2 needs to rotate inside the housing 1, in order to avoid jamming, the size of the reflector 2 is slightly smaller than the size of the opening end of the housing 1.

[0019] See Figure 1In this embodiment, a drive assembly 4 is provided on one side of the rear end of the angle adjustment assembly 3. The drive assembly 4 includes a drive motor 41, a first gear 42, a second gear 43, and a third gear 44. The drive motor 41 is fixedly connected to the inner wall of the housing 1. The first gear 42 is provided on the output shaft of the drive motor 41, and the second gear 43 is coaxially arranged on the first support rod 32. The third gear 44 meshes with the first gear 42 and the second gear 43. It can be understood that the drive motor 41 can drive the entire angle adjustment assembly 3 to rotate horizontally along the axial direction of the first support rod 32, thereby driving the rotation of the reflector 2. It can also be seen that the rotation of the reflector 2 driven by the drive assembly 4 does not affect the angle adjustment function of the reflector 2.

[0020] A fan assembly 5 is installed inside the second cavity 12. The fan assembly 5 includes a fan 51 and a heating assembly 52. ​​The fan 51 is fixedly connected to the housing 1. An air inlet cavity is spaced between the rear end of the fan 51 and the housing 1. The heating assembly 52 is installed at the front end of the fan 51 and is spaced apart by a support frame. When the fan assembly 5 is working, the air blown out by the fan 51 is heated by the heating assembly 52 into high-temperature hot air, and then enters the second cavity 12 through the air outlet 13, raising the ambient temperature inside the second cavity 12, thereby heating the rearview mirror 2 and removing the fog on the front of the rearview mirror 2. Furthermore, a temperature sensor (not shown in the figure) is installed inside the first cavity 11 on the housing 1. The temperature sensor detects the temperature inside the first cavity 11 and feeds the temperature value detected by the temperature sensor back to the controller inside the rearview mirror. The temperature value is compared with the preset temperature value inside the controller. When the temperature value is higher than the preset value, the controller controls the fan assembly 5 to stop working to prevent the temperature inside the first cavity 11 from becoming too high and to protect the components inside the first cavity 11. When it is necessary to remove rainwater from the front of the rearview mirror 2, simply control the drive motor 41 to rotate the angle adjustment component 3, thereby causing the side of the rearview mirror 2 closest to the air outlet 13 to rotate inwards towards the housing 1. This allows the hot air generated by the fan component 5 to blow towards the front of the rearview mirror 2, accelerating the evaporation of rainwater on the rearview mirror 2 and thus quickly removing the rainwater. It is worth mentioning that after cleaning the front of the rearview mirror 2, the drive motor 41 automatically returns to its initial position under the control of the controller, thus not affecting the rearview mirror's angle observation function. Furthermore, the housing 1 has a drainage groove 14 located at the lower end of the reflector; the drainage groove 14 is designed to drain the rainwater flowing down the front of the rearview mirror 2 to the outside of the housing 1, preventing rainwater from entering the interior of the housing 1.

[0021] Multiple air inlets 121 are provided on the side of the housing 1 located at the rear end of the fan 51. The air inlets 121 are used to connect the second cavity 12 with the outside, so that when the fan 51 is working, outside air enters the second cavity 12 through the air inlets 121. Multiple air outlets 111 are provided on the side of the housing 1 located at the first cavity 11. The air outlets 111 are used to connect the first cavity 11 with the outside. By providing the air outlets 111, some of the hot air blown in by the fan assembly 5 can be discharged from the first cavity 11 through the air outlets 111, reducing the air pressure inside the first cavity 11 and preventing the air pressure inside the first cavity 11 from becoming too high, which could damage the rearview mirror.

[0022] In summary, the rearview mirror assembly in the above embodiments of this utility model, by setting a driving component in the first cavity and a fan component in the second cavity within the housing, utilizes the hot air generated by the fan component to blow into the first cavity, raising the temperature of the rear end of the rearview mirror and heating the entire mirror. The heated mirror then removes fog. When there is rainwater on the front of the rearview mirror, simply activating the driving component simultaneously causes the mirror to rotate, guiding the hot air generated by the fan component to the front of the mirror. This hot air not only cleans the rainwater but also accelerates its evaporation, thus removing rainwater from the front of the rearview mirror.
