Description
Technical Field
[0001] The utility model relates to the technical field of vehicle components, in particular to an exterior rearview mirror structure. Simultaneously, the utility model also relates to a vehicle provided with the exterior rearview mirror structure. Background Art
[0002] Exterior mirrors play a crucial role in driving. They allow drivers to clearly observe oncoming traffic, allowing them to accurately determine whether conditions are safe for lane changes or overtaking. They also help drivers effectively monitor traffic on both sides of the vehicle, especially when merging or turning, ensuring there are no other vehicles or obstacles nearby. Furthermore, the driver's field of view, as presented by the exterior mirrors, allows them to anticipate and avoid potential traffic conflicts, significantly reducing the risk of accidents.
[0003] Existing rearview mirrors often have the following problems: ① Dust, rain, and even ice, frost, and fog often accumulate on the glass surface. This series of phenomena will cause the mirror surface to become blurry, which in turn seriously affects the driving field of vision. Even if a channel is added to blow away water droplets on the mirror surface, due to factors such as low wind speed and the ability to only blow out cold air, it cannot blow off ice and highly sticky objects, resulting in low efficiency. ② When the turn signal light strip is illuminated, it generates heat, and this heat cannot be effectively dissipated from the inside of the rearview mirror. This not only accelerates the aging of the turn signal and reduces the service life of the lamp, but the heat generated also causes thermal aging of surrounding components, reducing the strength of the surrounding parts. Utility Model Content
[0004] In view of this, the present invention aims to provide an exterior rearview mirror structure to improve the heat dissipation effect of the turn signal lamp and to better remove frost or sticky dirt on the rearview mirror lens.
[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:
[0006] An exterior rearview mirror structure comprises a mirror housing provided with a rearview mirror lens, a mounting seat and a turn signal lamp provided in the mirror housing, and a turn signal lampshade assembled with the mirror housing;
[0007] An air inlet is provided on the front side of the mirror housing, and an air outlet is provided on the rear side of the mirror housing, which is arranged toward the rearview mirror lens. An air duct is formed by the mounting base, the turn signal lampshade and the mirror housing, and two ends of the air duct are respectively connected to the air inlet and the air outlet;
[0008] The turn signal lamp is arranged in the air duct and mounted on the mounting seat.
[0009] Furthermore, the cross-sectional area of the air duct gradually decreases from the air inlet to the air outlet.
[0010] Furthermore, the turn signal lamp is in the shape of a long strip extending along the length direction of the air duct.
[0011] Furthermore, the mounting seat is in an arc shape convex toward one side of the mirror housing.
[0012] Furthermore, the mirror housing includes a mirror housing body and a mirror ring surrounding the rearview mirror lens and protruding from the outer surface of the rearview mirror lens;
[0013] The air inlet is arranged on the mirror housing body, and the air outlet is arranged on the mirror ring.
[0014] Furthermore, in the left-right direction of the vehicle, the air outlet is arranged at an end of the mirror housing away from the vehicle body.
[0015] Furthermore, the air outlet is an elliptical hole provided on the mirror ring, and the long axis direction of the elliptical hole is consistent with the height direction of the exterior rearview mirror structure.
[0016] Furthermore, a filter is provided at the air inlet; and / or,
[0017] The air inlet is rectangular.
[0018] Furthermore, guide ribs are provided on the side walls of the air duct, and the guide ribs extend along the length direction of the air duct.
[0019] Compared with the prior art, the present invention has the following advantages:
[0020] The exterior rearview mirror structure described in the present invention forms an air duct by making the mounting base on which the turn signal is installed, the turn signal lampshade and the mirror shell surrounding structure, and the air outlet of the air duct is arranged toward the rearview mirror lens. Therefore, when the turn signal is working and generates heat, the airflow in the air duct can take away the heat and dissipate it in time, which can effectively avoid the accumulation of heat inside the air duct, thereby slowing down the aging speed of the turn signal and extending the service life of the lamp. In addition, after the airflow in the air duct is heated by the turn signal, it helps to quickly remove frost or sticky dirt on the rearview mirror lens, thereby improving the use effect of the exterior rearview mirror structure.
[0021] In addition, the cross-sectional area of the air duct gradually decreases from the air inlet to the air outlet, which can gradually increase the flow rate of the air flow in the air duct, and then concentrate the air flow on the rearview mirror lens, making the wind force blowing towards the rearview mirror lens stronger, thereby more effectively removing dust, rain, frost and other debris on the mirror surface, and improving the ability of the exterior rearview mirror to keep the lens clear under various weather conditions.
[0022] By setting the turn signal as a long strip extending along the length of the air duct, not only can the turn signal better adapt to the shape of the air duct and facilitate layout, but it can also increase the visual range of the turn signal and its contact area with the airflow, which can improve the heat dissipation effect of the turn signal; moreover, it can also better heat the airflow in the air duct, thereby better removing frost or sticky dirt on the rearview mirror lens.
[0023] Secondly, the mounting seat is in an arc shape that protrudes toward one side of the mirror housing, which not only gives it better structural strength and stability and reduces the need for reinforcing ribs; but also, the arc structure can guide the airflow in the air duct to flow more smoothly, reduce airflow resistance and turbulence, and improve the ventilation efficiency of the air duct, thereby better realizing functions such as cleaning and defrosting of the rearview mirror lens.
[0024] The mirror case consists of a mirror case body and a mirror ring, which facilitates the setting of air inlets and outlets. The mirror ring protrudes from the outer surface of the rearview mirror lens, which can prevent flying debris from directly hitting the lens during driving, reducing the risk of damage to the lens. At the same time, the air outlet on the mirror ring is closer to the lens, which can blow the airflow to the lens more concentratedly, thereby improving cleaning efficiency.
[0025] Furthermore, in the left and right directions of the vehicle, the air outlet is arranged at the end of the mirror housing away from the body, which can better utilize the airflow generated during the vehicle's driving, so that the airflow in the air duct and the external airflow cooperate with each other, thereby improving the cleaning effect of the rearview mirror lens, and preventing interference from the airflow around the body, resulting in poor outflow of the airflow in the air duct or unstable direction.
[0026] By providing the air outlet as an elliptical hole on the mirror ring, and with the long axis direction of the elliptical hole consistent with the height direction of the exterior rearview mirror structure, the edge lines of the elliptical hole are smoother and the force distribution is more even compared to holes of other shapes, which can better withstand the pressure of the airflow in the air duct and the influence of the external environment; moreover, the airflow can also flow more concentratedly along the height direction of the rearview mirror structure when blowing out, which can better cover the different height areas of the rearview mirror lens, ensuring that the entire lens can be effectively blown by the airflow, thereby improving the effect of removing dust, rain, frost and other debris.
[0027] Furthermore, by providing a filter at the air inlet, dust, sand, and other small particles can be prevented from entering the air duct, thereby maintaining the cleanliness of the air duct. This also prevents foreign matter from clogging the air duct or damaging the turn signal lights and rearview mirror lenses. Furthermore, the airflow from the air outlet is cleaner, effectively cleaning dust, rain, and other items from the rearview mirror lenses, thereby improving the cleaning effect. By designing the air inlet in a rectangular shape, a relatively large air intake area is provided, allowing more air to enter the air duct, thereby increasing the airflow within the air duct, improving the cleaning effect on the rearview mirror lenses, and more quickly removing dust, rain, frost, and other items from the rearview mirror lenses.
[0028] In addition, by providing guide ribs extending along the length of the side walls of the air duct, not only can the strength and rigidity of the side walls of the air duct be increased, which is beneficial to improving the installation stability of the turn signal, but also the direction of airflow can be optimized, preventing the airflow from generating vortices on the wall and reducing energy loss.
[0029] Another object of the present invention is to provide a vehicle provided with the exterior rearview mirror structure as described above.
[0030] The vehicle described in the present invention, by providing the exterior rearview mirror structure as described above, can not only effectively avoid heat accumulation inside the air duct, thereby slowing down the aging speed of the turn signal lamp and extending the service life of the lamp; moreover, the airflow in the air duct, after being heated by the turn signal lamp, helps to quickly remove frost or sticky dirt on the rearview mirror lens, thereby improving the use effect of the exterior rearview mirror structure.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0043] Example 1
[0044] Given that existing exterior rearview mirrors often have the following problems: dust, rain, ice, frost, and fog often accumulate on the mirror surface, blurring the mirror surface. Furthermore, when the turn signal 4 is illuminated, heat is generated, which cannot be effectively dissipated from the interior of the mirror, accelerating the aging of the turn signal. Therefore, this embodiment specifically provides a novel exterior rearview mirror structure, comprising a mirror housing 1 having a rearview mirror lens 2, a mounting base 5 and a turn signal 4 disposed within the mirror housing 1, and a turn signal lampshade 3 assembled with the mirror housing 1.
[0045] In addition, an air inlet 1011 is provided on the front side of the mirror housing 1, and an air outlet 1021 is provided on the rear side of the mirror housing 1, which is arranged toward the rearview mirror lens 2. The mounting base 5, the turn signal lampshade 3 and the mirror housing 1 form an air duct K, and the two ends of the air duct K are respectively connected to the air inlet 1011 and the air outlet 1021, and the turn signal 4 is arranged in the air duct K and mounted on the mounting base 5.
[0046] The exterior rearview mirror structure of this embodiment forms an air duct K by enclosing the mounting base 5 on which the turn signal 4 is mounted, the turn signal lampshade 3, and the mirror housing 1. The air outlet 1021 of the air duct K is positioned toward the rearview mirror lens 2. Consequently, when the turn signal 4 generates heat during operation, the airflow in the air duct K promptly carries away and dissipates the heat, effectively preventing heat accumulation within the air duct K. This slows down the aging of the turn signal 4 and extends the service life of the lamp. Furthermore, the airflow in the air duct K, after being heated by the turn signal 4, helps quickly remove frost or sticky dirt from the rearview mirror lens 2, thereby improving the performance of the exterior rearview mirror structure.
[0047] Based on the above introduction, an exemplary structure of the exterior rearview mirror of this embodiment is referred to Figures 1 to 3 As shown in Figure 3 The arrows in the center indicate the airflow path. The overall structure of the exterior rearview mirror is the same as in the prior art. In addition to the aforementioned mirror housing 1, mounting base 5, and turn signal 4, it also includes a mounting base that secures the mirror housing to the vehicle body, as well as a drive motor and transmission mechanism that drives the mirror lens 2. The specific structures of the mounting base 5, mounting base, transmission mechanism, and turn signal 4 can be referenced from the prior art. This embodiment primarily describes the structure at the air duct K. Furthermore, similar to the prior art, the turn signal lampshade 3 is typically transparent.
[0048] The mounting base 5 of this embodiment is specifically mounted on the fixing base, and can generally be fixed to the fixing base by a screw connection or a clamping structure, and screw connection and clamping are commonly used structures by those skilled in the art and will not be described in detail here. Figure 3 In the embodiment, the mirror housing 1 includes a mirror housing body 101 and a mirror ring 102 surrounding the rearview mirror lens 2 and protruding from the outer surface of the rearview mirror lens 2, and the air inlet 1011 is provided on the mirror housing body 101, and the air outlet 1021 is provided on the mirror ring 102.
[0049] The mirror ring 102 protrudes from the outer surface of the rearview mirror lens 2, providing some protection for the rearview mirror lens 2. During driving, the mirror ring 102 can prevent some flying debris from directly hitting the rearview mirror lens 2, reducing the risk of damage to the rearview mirror lens 2. Furthermore, the air outlet 1021 is positioned on the mirror ring 102, placing the air outlet 1021 closer to the rearview mirror lens 2, allowing for more concentrated airflow towards the rearview mirror lens 2 and improving cleaning efficiency.
[0050] like Figure 1 As shown in , as a further embodiment, an air outlet 1021 is located at the end of the mirror housing 1 away from the vehicle body in the left-right direction of the vehicle. If the air outlet 1021 were located at the end closer to the vehicle body, it might be interfered with by the surrounding airflow, resulting in poor or unstable airflow within the air duct K. Placing the air outlet 1021 at the end farther from the vehicle body reduces the impact of the surrounding airflow on the airflow within the air duct K, better utilizes the airflow generated during vehicle travel, and more stably directs it toward the rearview mirror lens 2, improving cleaning reliability.
[0051] Continue to refer to Figure 1 As shown in , as a preferred embodiment, the air outlet 1021 is an elliptical hole provided on the lens ring 102, with the major axis of the elliptical hole aligned with the height direction of the exterior rearview mirror structure. This arrangement allows the airflow to flow more concentratedly along the height direction of the rearview mirror during blowing, better covering the different height areas of the rearview mirror lens 2, ensuring that the entire rearview mirror lens 2 is effectively blown by the airflow, thereby improving the removal of debris such as dust, rain, and frost. Moreover, compared to holes of other shapes, the elliptical hole has smoother edges and more even force distribution, which can better withstand the pressure of the airflow within the air duct K and the influence of the external environment.
[0052] It is understandable that, in addition to setting the air outlet 1021 as an elliptical hole, it is also feasible to set it as a circular hole, a rectangular hole or other shapes.
[0053] In this embodiment, Figure 3 As shown in , as a preferred embodiment, the mounting seat 5 is in the shape of an arc that bulges toward one side of the mirror housing 1. This structure can not only increase the strength and stability of the mounting seat 5, but also reduce the setting of the reinforcing ribs, so that the vibration of the exterior rearview mirror can be reduced during driving, which is beneficial to improving the installation stability of the turn signal lamp 4. In addition, the mounting seat 5 is in an arc shape, which can also enable the mounting seat 5 to guide the airflow in the air duct K to flow more smoothly, reduce the resistance and turbulence of the airflow, and improve the ventilation efficiency of the air duct K, thereby better realizing the functions of cleaning and defrosting the rearview mirror lens 2. In addition, it should be noted that the mounting seat 5 is in an arc shape, which includes both a standard arc structure and a Figure 3The overall visual appearance is arc-shaped.
[0054] In addition, if Figure 3 As shown in FIG, as a preferred embodiment, the turn signal lamp 4 is in the shape of an elongated strip extending along the length of the air duct K. This configuration not only allows the turn signal lamp 4 to better adapt to the shape of the air duct K, facilitating its placement, but also increases the visible range of the turn signal lamp 4 and its contact area with the airflow, thereby improving the heat dissipation effect of the turn signal lamp 4. It also effectively heats the airflow within the air duct K, thereby effectively removing frost or sticky dirt from the rearview mirror lens 2.
[0055] Continue to refer to Figure 3 As shown in , as a further embodiment, in this embodiment, the cross-sectional area of the air duct K gradually decreases from the air inlet 1011 to the air outlet 1021. This design has the advantage of gradually increasing the airflow velocity within the air duct K, allowing the airflow to exert a concentrated force on the rearview mirror lens 2. When the airflow reaches the air outlet 1021, the velocity is at its highest, and the force blowing towards the rearview mirror lens 2 is stronger, effectively removing dust, rain, frost, and other sticky dirt from the mirror surface, thereby improving the clarity of the exterior rearview mirror lens 2 in various weather conditions.
[0056] In addition, as a further embodiment, Figure 4 As shown in FIG, guide ribs 6 are provided on the sidewalls of the air duct K, extending along the length of the air duct K. The provision of the guide ribs 6 can guide the airflow within the air duct K. Furthermore, since the guide ribs 6 extend along the length of the air duct K, they can facilitate smoother airflow, reducing turbulence and eddies in the airflow and improving airflow stability and directionality. This helps ensure that the airflow entering from the air inlet 1011 can efficiently flow to the air outlet 1021 and be concentratedly blown toward the rearview mirror lens 2, thereby enhancing the cleaning effect on the lens.
[0057] In addition, the guide ribs 6 can also change the flow pattern of the airflow in the air duct K, so that the airflow has a certain acceleration effect when flowing through the guide ribs 6. Moreover, the guide ribs 6 can also increase the strength and rigidity of the side walls of the air duct K, which can reduce the risk of deformation and damage to the air duct K. It can also effectively prevent the vibration of the exterior rearview mirror during vehicle driving, which helps to improve the installation stability of the turn signal 4.
[0058] like Figure 2In a preferred embodiment, the air inlet 1011 of this embodiment is rectangular. This design allows the air inlet 1011 to provide a relatively large air intake area. Compared with other shapes, such as circular air inlets 1011, the rectangular air inlet 1011 can allow more air to enter the air duct K, thereby helping to increase the airflow within the air duct K, improving the cleaning effect of the rearview mirror lens 2, and more quickly removing dust, rain, frost, etc. on the rearview mirror lens 2. It is understandable that in addition to setting the air inlet 1011 in a rectangular shape, it is also feasible to set it in a circular, elliptical, or other shape.
[0059] In this embodiment, as a further embodiment, a filter (not shown) is provided at the air inlet 1011. The filter prevents impurities such as dust and sand from entering the air duct K and accumulating therein, thereby maintaining the cleanliness of the air duct K. Furthermore, the filter prevents impurities from entering the air duct K, thereby reducing wear and damage to components within the air duct K, such as the turn signal lamp 4 and the rearview mirror lens 2. Furthermore, the air filtered by the filter is cleaner when it is blown out of the air outlet 1021, effectively cleaning dust, rainwater, and the like from the rearview mirror lens 2, thereby improving the cleaning effect.
[0060] The rearview mirror structure of this embodiment, by employing the above-described structure, effectively prevents heat generated by the turn signal lamp 4 from accumulating within the rearview mirror, thereby slowing down the aging of the turn signal lamp 4 and extending the lamp's service life. Furthermore, the airflow within the air duct K, after being heated by the turn signal lamp 4, helps quickly remove frost or sticky dirt from the rearview mirror lens 2, thereby improving the performance of the exterior rearview mirror structure.
[0061] Example 2
[0062] This embodiment relates to a vehicle, in which the above exterior rearview mirror structure is provided.
[0063] The vehicle of this embodiment, by installing the exterior rearview mirror structure of the first embodiment, can not only effectively prevent heat accumulation inside the rearview mirror, thereby slowing down the aging of the turn signal lamp 4, but also, the airflow in the air duct K, after being heated by the turn signal lamp 4, helps to quickly remove frost or sticky dirt from the rearview mirror lens 2, thereby improving the performance of the exterior rearview mirror structure and further enhancing driving safety.
[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
