Description

Technical Field

[0001] This application relates to the technical field of rearview mirrors, and particularly to a rearview mirror and a vehicle. Background Art

[0002] With the increasing intelligence of the whole vehicle, in-vehicle streaming media rearview mirrors are more and more widely used. Due to the presence of electronic components inside and their small volume, the temperature of the rearview mirror is relatively high. Therefore, the in-vehicle streaming media rearview mirror usually needs to dissipate heat generated by the internal electronic components to suppress the temperature rise of the electronic components and keep the electronic components operating within a predetermined temperature range.

[0003] In the prior art, heat dissipation holes are usually formed on the housing of the in-vehicle streaming media rearview mirror to dissipate heat from the electronic components inside the rearview mirror. However, the in-vehicle streaming media rearview mirror not only needs to dissipate heat from the internal electronic components but also needs to prevent the internal electronic components from coming into contact with liquid to protect the safety of the in-vehicle streaming media rearview mirror. Summary of the Utility Model

[0004] An embodiment of this application provides a rearview mirror and a vehicle. The rearview mirror has both good heat dissipation effect and good waterproof effect.

[0005] In a first aspect, an embodiment of this application provides a rearview mirror. The rearview mirror includes a housing, and the housing has a diversion groove, a heat dissipation groove, and a communication hole. The diversion groove is formed on the outer surface of the housing, a discharge port is provided at one end of the diversion groove, the heat dissipation groove is formed on the inner surface of the housing, and the communication hole communicates the diversion groove and the heat dissipation groove. The communication hole is higher than the bottom wall of the diversion groove.

[0006] Based on the housing of the embodiment of this application, the diversion groove communicates with the outer surface of the housing, the heat dissipation groove communicates with the inner surface of the housing, and the communication hole communicates the diversion groove and the heat dissipation groove at the same time. Thus, the inner side of the housing communicates with the outer side of the housing through the heat dissipation groove, the communication opening, and the diversion groove, making the housing have a good heat dissipation effect; in addition, after the water on the outer side of the housing enters the diversion groove, since the bottom wall of the first cross-section is higher than the bottom wall of the diversion groove, the water in the diversion groove must overflow over the bottom wall of the first cross-section to overflow from the diversion groove to the heat dissipation groove and then enter the housing. However, before that, the water in the diversion groove has been discharged from the diversion groove through the discharge port, making the rearview mirror have good waterproof performance while having good heat dissipation performance.

[0007] In some embodiments of this application, the communication hole forms a first communication opening on the side wall of the diversion groove, the communication hole forms a second communication opening on the side wall of the heat dissipation groove, the top wall of the second communication opening is flush with the bottom wall of the heat dissipation groove, and there is a spacing between the bottom wall of the first communication opening and the bottom wall of the diversion groove.

[0008] Based on the above embodiments, due to the characteristic that hot air rises, the second communication opening is flush with the bottom wall of the heat dissipation groove. After the hot air enters the heat dissipation groove, it will enter the communication hole along the bottom wall of the heat dissipation groove and the second communication opening, without causing the hot air to accumulate in the heat dissipation groove; there is a distance in the height direction between the bottom wall of the first communication opening and the bottom wall of the diversion groove. At this time, the first communication opening can be used as the first cross-section, ensuring that the water in the diversion groove will not enter the housing through the communication hole and the heat dissipation groove.

[0009] In some embodiments of the present application, the first communication opening and the second communication opening coincide.

[0010] Based on the above embodiments, at this time, the length of the communication hole is zero, reducing the processing difficulty of the communication hole, and the hot air can reach outside the housing from inside the housing through a shorter distance, improving the heat dissipation performance of the housing.

[0011] In some embodiments of the present application, the distance between the bottom wall of the first communication opening and the bottom wall of the diversion groove is d, and 5mm ≤ d ≤ 10mm.

[0012] Based on the above embodiments, the distance greater than or equal to 5mm between the bottom wall of the first communication opening and the bottom wall of the diversion groove ensures the waterproof effect of the housing, and the distance less than or equal to 10mm between the bottom wall of the first communication opening and the bottom wall of the diversion groove ensures that the thickness of the housing will not be too thick.

[0013] In some embodiments of the present application, the housing is convexly provided with a shielding eaves, and the shielding eaves are located above the first communication opening in the height direction.

[0014] Based on the above embodiments, the shielding eaves reduce the probability that the water outside the housing directly enters the communication hole through the first communication opening, causing the water outside the housing to enter the diversion groove as much as possible, further improving the waterproof performance of the housing.

[0015] In some embodiments of the present application, the communication hole includes a plurality of interconnected communication segments, and the axes of adjacent communication segments are arranged at an angle.

[0016] Based on the above embodiments, even if the water outside the housing enters the communication hole through the first communication opening, due to the axes of the plurality of communication segments being arranged at an angle, the liquid entering the communication hole through the first communication opening is not likely to enter the housing due to the multi-segment communication segments, improving the waterproof performance of the housing.

[0017] In some embodiments of the present application, the bottom wall of the diversion groove gradually rises in the height direction from one end of the drainage port to the end far from the drainage port.

[0018] Based on the above embodiments, the water entering the diversion groove will flow rapidly along the bottom wall of the diversion groove and be discharged from the diversion groove through the discharge port.

[0019] In some embodiments of the present application, the diversion groove, the heat dissipation groove, and the communication hole are all provided on the top wall of the housing.

[0020] Based on the above embodiments, due to the characteristic that hot air rises, by opening the diversion groove, the heat dissipation groove, and the communication hole on the top wall of the housing, the housing has a good heat dissipation effect.

[0021] In some embodiments of the present application, the rearview mirror is configured as a streaming media rearview mirror. The streaming media rearview mirror includes a display screen, electronic devices, and a mirror rod. The display screen is connected to the housing, and an installation cavity is defined between the display screen and the housing. The heat dissipation groove communicates with the installation cavity; the electronic devices are disposed in the installation cavity and are connected to the housing; the mirror rod is connected to the housing, and the mirror rod is used to connect to the vehicle body.

[0022] Based on the above embodiments, the streaming media rearview mirror has good heat dissipation performance, which can ensure that the electronic devices of the streaming media rearview mirror are timely cooled, and further ensure that the streaming media rearview mirror is at an appropriate working temperature; the streaming media rearview mirror has good waterproof performance, which can ensure the safety of the electronic devices inside the streaming media rearview mirror.

[0023] In a second aspect, embodiments of the present application provide a vehicle, including the rearview mirror as described above.

[0024] Based on the vehicle of the embodiments of the present application, since it has the above rearview mirror, and the rearview mirror has the above housing, the rearview mirror of the vehicle has good heat dissipation performance and waterproof performance, improving the reliability of the vehicle.

[0032] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] As the vehicle becomes more and more intelligent, in-vehicle streaming media rearview mirrors are more and more widely used. Since they have electronic components inside and are small in size, the temperature of the rearview mirror is relatively high. Therefore, the heat generated by the electronic components inside the in-vehicle streaming media rearview mirror usually needs to be dissipated to suppress the temperature rise of the electronic components and keep the electronic components operating within a predetermined temperature range.

[0034] In the prior art, heat dissipation holes are usually formed on the housing of the in-vehicle streaming media rearview mirror to dissipate heat from the electronic components inside the rearview mirror. However, the in-vehicle streaming media rearview mirror not only needs to dissipate heat from the internal electronic components, but also needs to prevent the internal electronic components from coming into contact with liquid to protect the safety of the in-vehicle streaming media rearview mirror.

[0035] To solve the above technical problems, an embodiment of the present application provides a rearview mirror and a vehicle, which have both good heat dissipation effect and good waterproof effect.

[0036] Please refer to Figures 1 to 3 As shown, in a first aspect, an embodiment of the present application provides a rearview mirror, which includes a housing 10. The housing 10 has a diversion groove 11, a heat dissipation groove 12 and a communication hole 13. The diversion groove 11 is formed on the outer surface of the housing 10, and the diversion groove 11 forms a discharge port 111 for discharging liquid on the surface of the housing 10. The heat dissipation groove 12 is formed on the inner surface of the housing 10. The communication hole 13 communicates the diversion groove 11 and the heat dissipation groove 12, and the communication hole 13 is higher than the bottom wall of the diversion groove 11. In the present application, the communication hole 13 being higher than the bottom wall of the diversion groove 11 means that as a whole, any part of the communication hole 13 is higher than the bottom wall of the diversion groove 11.

[0037] The diversion groove 11 is used to divert the liquid entering the diversion groove 11. The diversion groove 11 can be arranged at any position of the housing 10. Please refer to Figure 1 As shown, the diversion groove 11 of the embodiment of the present application is arranged on the top wall of the housing 10. It can be understood that the diversion groove 11 can also be arranged on the side wall and the bottom wall of the housing 10.

[0038] The length direction of the diversion groove 11 can be arranged in any direction, but it is necessary to ensure that one side of the diversion groove 11 distributed along its own length direction is connected to the outer surface of the housing 10 to form a discharge port 111.

[0039] In addition, to improve the heat dissipation effect of the housing 10, the notch of the diversion groove 11 is connected to the outer surface of the housing 10 to increase the connection area between the diversion groove 11 and the outer surface of the housing 10, thereby increasing the heat dissipation capacity of the housing 10.

[0040] The heat dissipation groove 12 cooperates with the communication hole 13 and the diversion groove 11 to realize the heat dissipation function of the housing 10. Please refer to Figure 3 As shown, it can be understood that the notch of the heat dissipation groove 12 must be connected to the inner surface of the housing 10 in order to dissipate the hot air inside the housing to the outside of the housing through the heat dissipation groove 12, the communication hole 13 and the diversion groove 11.

[0041] In some embodiments of the present application, to ensure the structural strength of the housing 10, the depth of the diversion groove 11 and the depth of the heat dissipation groove 12 do not exceed 0.7 of the thickness of the housing 10, so that the housing 10 can still have sufficient structural strength after the diversion groove 11 and the heat dissipation groove 12 are provided.

[0042] The communication hole 13 is used to connect the diversion groove 11 and the heat dissipation groove 12. To make the connection area between the heat dissipation groove 12 and the diversion groove 11 larger, the communication hole 13 connects any side wall of the diversion groove 11 parallel to its own length direction. At the same time, to make the connection area between the heat dissipation groove 12 and the communication hole 13 larger, the arrangement direction of the heat dissipation groove 12 is parallel to the arrangement direction of the diversion groove 11. At this time, the communication hole 13 connects any side wall of the heat dissipation groove 12 parallel to its own length direction.

[0043] Based on the housing 10 of the embodiments of the present application, the diversion groove 11 communicates with the outer surface of the housing 10, the heat dissipation groove 12 communicates with the inner surface of the housing 10, and the communication hole 13 communicates with both the diversion groove 11 and the heat dissipation groove 12. Thus, the inner side of the housing 10 communicates with the outer side of the housing 10 through the heat dissipation groove 12, the communication opening, and the diversion groove 11, enabling the housing 10 to have a good heat dissipation effect; in addition, after the water outside the housing 10 enters the diversion groove 11, since the bottom wall of the first cross-section is higher than the bottom wall of the diversion groove 11, the water in the diversion groove 11 must overflow the bottom wall of the first cross-section to overflow from the diversion groove 11 into the heat dissipation groove 12 and then enter the housing 10. However, before that, the water in the diversion groove 11 has been discharged from the diversion groove 11 through the flow discharge port 111, enabling the housing 10 to have good waterproof performance while having good heat dissipation performance.

[0044] Please refer to Figure 3 , Figure 4 or Figure 5 As shown, in some embodiments of the present application, the communication hole 13 forms a first communication opening 131 on the side wall of the diversion groove 11, and the communication hole 13 forms a second communication opening 132 on the side wall of the heat dissipation groove 12. The top wall of the second communication opening 132 is flush with the bottom wall of the heat dissipation groove 12, and there is a spacing between the bottom wall of the first communication opening 131 and the bottom wall of the diversion groove 11.

[0045] Due to the characteristic that hot air rises, the second communication opening 132 is flush with the bottom wall of the heat dissipation groove 12. After the hot air enters the heat dissipation groove 12, it will enter the communication hole 13 along the bottom wall of the heat dissipation groove 12 and the second communication opening 132, and will not cause the hot air to accumulate in the heat dissipation groove 12; there is a spacing between the bottom wall of the first communication opening 131 and the bottom wall of the diversion groove 11 in the height direction. At this time, the first communication opening 131 can be used as the first cross-section, ensuring that the water in the diversion groove 11 will not enter the housing 10 through the communication hole 13 and the heat dissipation groove 12.

[0046] In the embodiments of the present application, the shapes, numbers, etc. of the first communication opening 131 and the second communication opening 132 are not limited, as long as the first communication opening 131 can communicate with the diversion groove 11 and the second communication opening 132 can communicate with the heat dissipation groove 12. When the number of the first communication holes 13 is multiple, the first communication holes 13 can be configured in any shape such as rectangular, circular, etc., and the multiple first communication holes 13 can be arranged along the length direction of the diversion groove 11; when the number of the second communication holes 13 is multiple, the multiple first communication holes 13 can be arranged along the length direction of the heat dissipation groove 12; Please refer to Figure 2As shown, when the number of the first connecting hole 13 is one, the first connecting hole 13 is configured as a long strip opening, and the length direction of the first connecting hole 13 is parallel to the length direction of the guide groove 11; when the number of the second connecting hole 13 is one, the second connecting hole 13 is configured as a long strip opening, and the length direction of the first connecting hole 13 is parallel to the length direction of the heat dissipation groove 12.

[0047] The connecting hole 13 is used to connect the guide groove 11 and the heat dissipation groove 12. It can be understood that the shorter the length of the connecting hole 13, the easier it is for the hot air in the housing 10 to flow from the heat dissipation groove 12 to the guide groove 11. Therefore, please refer to Figure 4 As shown, in some embodiments of the present application, the first communication opening 131 and the second communication opening 132 overlap, and at this time, the length of the communication hole 13 is zero, which reduces the difficulty of processing the communication hole 13, and the hot air can reach the outside of the shell 10 from the inside of the shell 10 through a shorter distance, thereby improving the heat dissipation performance of the shell 10. However, in order to ensure that there is a spacing between the bottom wall of the first communication opening 131 and the bottom wall of the guide groove 11, that is, to ensure that there is a shell 10 structure separating the guide groove 11 and the heat dissipation groove 12, in the embodiment of the present application, from the bottom of the guide groove 11 to the notch of the guide groove 11 (from the outside of the shell 10 to the inside of the shell 10), the side wall of the guide groove 11 close to the heat dissipation groove 12 is gradually arranged away from the guide groove 11, and the side wall of the guide groove 11 close to the heat dissipation groove 12 is arranged along the height direction, so that the above two side walls form an angle between the guide groove 11 and the heat dissipation groove 12 to define the shell 10 structure.

[0048] In some embodiments of the present application, the distance between the bottom wall of the first connecting opening 131 and the bottom wall of the guide groove 11 is d, 5mm≤d≤10mm, for example, 6mm, 7mm, 8mm or 9mm, etc. The distance between the bottom wall of the first connecting opening 131 and the bottom wall of the guide groove 11 is greater than or equal to 5mm, which ensures the waterproof effect of the shell 10, and the distance between the bottom wall of the first connecting opening 131 and the bottom wall of the guide groove 11 is less than or equal to 10mm, which ensures that the thickness of the shell 10 is not too thick.

[0049] Please refer to Figure 3 , Figure 4 or Figure 5 As shown, in some embodiments of the present application, the shell 10 is provided with a shielding eave 14 convexly, and the shielding eave 14 is located above the first communication opening 131 along the height direction.

[0050] The shielding eaves 14 reduce the probability of water outside the shell 10 directly entering the connecting hole 13 from the first connecting opening 131 , so that the water outside the shell 10 enters the guide groove 11 as much as possible, further improving the waterproof performance of the shell 10 .

[0051] In some embodiments of the present application, the shielding eaves 14 are integrally formed with the housing 10, that is, when processing the diversion groove 11, the shielding eaves 14 are formed by a part of the housing 10 while avoiding the shielding eaves 14. In a specific embodiment of the present application, the shielding eaves 14 and the housing 10 are injection molded. Since the thicknesses of the housing 10 and the shielding eaves 14 are relatively thin, injection molding ensures the connection strength between the shielding eaves 14 and the housing 10.

[0052] Please refer to Figure 5 As shown, in some embodiments of the present application, the communication holes 13 include a plurality of communicating sections that communicate with each other, and the axes of adjacent communicating sections are arranged at an angle. Even if the water outside the housing 10 enters the communication holes through the first communication opening 131, due to the axes of the plurality of communicating sections being arranged at an angle, the waterproof performance of the housing 10 is improved.

[0053] In some embodiments of the present application, the bottom wall of the diversion groove 11 gradually rises in the height direction from one end of the drainage port 111 to the end far from the drainage port 111 (the depth of the diversion groove 11 gradually increases from the end far from the drainage port 111 to the drainage port 111). In this way, the water entering the diversion groove 11 will flow rapidly along the bottom wall of the diversion groove 11 and be discharged from the drainage port 111.

[0054] To improve the waterproof performance of the housing 10 of the present application, in the embodiments of the present application, the side walls of the diversion groove 11 can be coated with a hydrophobic coating, for example, fluorocarbon coatings (PTFE, FEP, ECTE, ETFE, PFA, etc.) or polymer melt polymers (polyolefins, polycarbonates, polyamides, polyacrylonitriles, etc.), or the housing 10 itself is made of a water-conveying material.

[0055] In some embodiments of the present application, the diversion groove 11, the heat dissipation groove 12, and the communication holes 13 are all provided on the top wall of the housing 10. Due to the property that hot air rises, by arranging the diversion groove 11, the heat dissipation groove 12, and the communication holes 13 on the top wall of the housing 10, the housing 10 has a good heat dissipation effect.

[0056] In some embodiments of the present application, the rearview mirror is configured as a streaming media rearview mirror. The streaming media rearview mirror includes a display screen 20, electronic devices, and a mirror rod 30. The display screen 20 is connected to the housing 10, and an installation cavity is defined between the display screen 20 and the housing 10; the heat dissipation groove 12 communicates with the installation cavity; the electronic devices are arranged in the installation cavity and are connected to the housing 10; the mirror rod 30 is connected to the housing 10, and the mirror rod 30 is used to connect to the vehicle body.

[0057] It can be understood that after the rearview mirror in the embodiments of the present application is configured as an in-vehicle streaming media rearview mirror, the streaming media rearview mirror can cooperate with a camera arranged behind the vehicle body to obtain a wider field of view and display it on the display screen 20 of the rearview mirror.

[0058] Please refer to Figure 1As shown Figure 1 FIG. Figure 1 is a schematic structural diagram of a rearview mirror in an embodiment of the present application. A diversion groove 11 is provided on the top wall of a housing 10 and is arranged along the thickness direction of the housing 10. One end of the diversion groove 11 far away from a display screen 20 communicates with the rear side of the housing 10 to form a drainage port 111, preventing water in the diversion groove 11 from flowing to the display screen 20 of the rearview mirror.

[0059] A mirror rod 30 is used to connect the housing 10 and the vehicle body. In the embodiment of the present application, the shape, material, etc. of the mirror rod 30 are not limited, as long as the mirror rod 30 can connect the housing 10 and be fixed to the vehicle body.

[0060] In a second aspect, an embodiment of the present application provides a vehicle including the rearview mirror as described above.

[0061] Based on the vehicle of the embodiment of the present application, since it has the above-mentioned rearview mirror and the rearview mirror has the above-mentioned housing 10, the rearview mirror of the vehicle has good heat dissipation performance and waterproof performance, improving the reliability of the vehicle.
