The outside rear-view mirror shell comprises a shell main body and a first water retaining structure located in the shell main body, a water leakage hole is formed in the bottom of the shell main body, and the first water retaining structure is at least partially opposite to the water leakage hole in the axial direction of the water leakage hole, that is, the first water retaining structure is at least partially opposite to the water leakage hole in the axial direction of the water leakage hole. At least part of the first water retaining structure is located above the water leakage hole, so that even if water outside the outside rear-view mirror upwards enters the water leakage hole (for example, the water is sprayed upwards or splashed into the water leakage hole), most of the water can be directly blocked by the first water retaining structure above the water leakage hole and falls back to the outside through the water leakage hole. And external water can be well prevented from splashing upwards or being sprayed to electronic components in the shell main body through the water leakage holes, so that the waterproof performance of the outside rear-view mirror is improved.

Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, specifically to an exterior rearview mirror housing, an exterior rearview mirror, and a vehicle. Background Technology

[0002] With the rapid development of intelligent electronic technology in recent years, the internal components of vehicle exterior rearview mirror lenses have become increasingly complex, leading to higher requirements for waterproofing and water resistance. However, since the rearview mirror lens is located outside the vehicle, moisture inevitably seeps in. Therefore, related designs typically include drainage holes at the bottom of the lens housing to allow water to escape. However, this also means that water stains and raindrops can enter the lens housing through these holes, especially during vehicle cleaning and washing. High-pressure water from outside can easily spray upwards from these drainage holes onto the electronic components, causing them to malfunction. Utility Model Content

[0003] The present invention aims to improve the waterproof performance of exterior rearview mirrors.

[0004] To solve the above problems, this utility model provides an exterior rearview mirror housing, including a housing body and a first water-blocking structure located inside the housing body. A water-draining hole is provided at the bottom of the housing body, and the first water-blocking structure is at least partially opposite to the water-draining hole in the axial direction of the water-draining hole.

[0005] The exterior rearview mirror housing provided by this utility model has, but is not limited to, the following technical effects compared with the prior art:

[0006] The drainage hole of the exterior rearview mirror housing can be located at the bottom of the housing body, similar to related technologies, to allow water that seeps into the housing body to drain out naturally. The difference lies in the addition of a first water-blocking structure inside the housing body. This first water-blocking structure is at least partially opposite the drainage hole in its axial direction. In other words, at least a portion of the first water-blocking structure is positioned above the drainage hole. Thus, even if water from outside the exterior rearview mirror enters the drainage hole upwards (e.g., by spraying or splashing upwards), most of the water will be directly blocked by the first water-blocking structure above the drainage hole and fall back to the outside through the drainage hole. This effectively prevents external water from splashing or spraying upwards through the drainage hole onto the electronic components inside the housing body, improving the waterproofness of the exterior rearview mirror and thus enhancing the safety and effectiveness of the electronic components.

[0007] Furthermore, the first water-blocking structure includes a first peripheral side portion and an axial side portion. One end of the first peripheral side portion is connected to the shell body, and the first peripheral side portion is located at the edge of the water leakage hole. The axial side portion is connected to the other end of the first peripheral side portion, and the axial side portion and the water leakage hole are arranged opposite to each other in the axial direction of the water leakage hole.

[0008] Furthermore, the first circumferential side portion surrounds a portion of the drain hole along its circumference; and / or, the first circumferential side portion is located on the side of the drain hole closer to the electronic components within the housing body; and / or, the dimensions of the axial side portion match the drain hole.

[0009] Furthermore, the shell body includes a bottom plate and a side wall portion, at least a portion of the bottom plate has an upwardly bent side wall portion, the drain hole is located on the bottom plate adjacent to the side wall portion, and the first peripheral side portion is located on the side of the drain hole away from the side wall portion.

[0010] Furthermore, the exterior rearview mirror housing also includes a second water-blocking structure, the second water-blocking structure including a second circumferential side portion located at the edge of the water leakage hole, the second circumferential side portion surrounding a portion of the water leakage hole circumferentially, and a radial water flow channel forming between the second circumferential side portion and the first circumferential side portion.

[0011] Furthermore, the second water-blocking structure also includes a third circumferential side portion, which is arranged around the water leakage hole and corresponds to the position of the radial water flow channel. The inner diameter of the third circumferential side portion is larger than the outer diameter of the first circumferential side portion and the second circumferential side portion.

[0012] Furthermore, the second water-blocking structure also includes a connecting part, one end of the third peripheral side is connected to the second peripheral side through the connecting part; the outer wall of the first peripheral side is provided with a groove, the groove extends along the axial direction of the water leakage hole, and the end of the third peripheral side away from the connecting part is provided with a protrusion, the protrusion slidingly engaging with the groove.

[0013] Furthermore, the axial side portion, the first peripheral side portion, and the shell body are integrally formed structures.

[0014] This utility model also provides an exterior rearview mirror, including the exterior rearview mirror housing as described above.

[0015] Since the technical improvements and effects of the aforementioned exterior rearview mirror are at least the same as those of the exterior rearview mirror housing, the exterior rearview mirror will not be described in detail again.

[0016] This utility model also provides a vehicle, including the exterior rearview mirror as described above.

[0017] Since the technological improvements and effects of the vehicle are at least the same as those of the aforementioned exterior rearview mirror, the vehicle will not be described in detail again. Attached Figure Description

[0028] See Figure 1-4 An embodiment of the present invention provides an exterior rearview mirror housing, comprising a housing body 1 and a first water-blocking structure 2 located inside the housing body 1. A water-draining hole 111 is provided at the bottom of the housing body 1, and the first water-blocking structure 2 is at least partially opposite to the water-draining hole 111 in the axial direction of the water-draining hole 111.

[0029] In related technologies, the exterior rearview mirror housing does not have the aforementioned first water-blocking structure 2 or other water-blocking structures. For example, when washing a vehicle, if the external cleaning equipment uses high-pressure water to rinse the body or tires below the exterior rearview mirror, the high-pressure water may splash upwards and pass through the drain hole 111, thereby causing water to get into the electronic components inside the housing body 1, posing a risk of failure. Similarly, when washing a vehicle, if the external cleaning equipment uses high-pressure water to rinse the bottom outer wall of the exterior rearview mirror, the high-pressure water may directly spray upwards through the drain hole 111, thereby causing water to get into the electronic components inside the housing body 1, posing a risk of failure. Furthermore, when driving in rainy weather or when a vehicle passes through a flooded road, water on the road surface can easily splash upwards under the fast-moving wheels and directly splash into the electronic components inside the housing body 1 through the drain hole 111, leading to a risk of failure for the electronic components.

[0030] In this embodiment, the drainage hole 111 of the exterior rearview mirror housing can be set at the bottom of the housing body 1, just like in related technologies, so that water that has seeped into the housing body 1 can be naturally discharged outward. The difference lies in the fact that a first water-blocking structure 2 is also provided inside the shell body 1, and the first water-blocking structure 2 is at least partially opposite to the water-leaking hole 111 in the axial direction. That is, at least part of the first water-blocking structure 2 corresponds to the position of the water-leaking hole 111 in the axial direction. In other words, at least part of the first water-blocking structure 2 is located above the water-leaking hole 111. Thus, even if water from outside the rearview mirror enters the water-leaking hole 111 upwards (e.g., sprayed upwards or splashed into the water-leaking hole 111), most of the water will be directly blocked by the first water-blocking structure 2 above the water-leaking hole 111 and fall back to the outside through the water-leaking hole 111. This can effectively prevent external water from splashing or spraying upwards through the water-leaking hole 111 onto the electronic components inside the shell body 1, thereby improving the waterproofness of the rearview mirror and thus improving the safety of its internal electronic components and ensuring the effectiveness of the electronic components.

[0031] See Figure 1-4 Optionally, the first water-blocking structure 2 includes a first peripheral side portion 21 and an axial side portion 22. One end of the first peripheral side portion 21 is connected to the shell body 1, and the first peripheral side portion 21 is located at the edge of the water leakage hole 111. The axial side portion 22 is connected to the other end of the first peripheral side portion 21, and the axial side portion 22 and the water leakage hole 111 are arranged opposite to each other in the axial direction of the water leakage hole 111.

[0032] In this embodiment, the axial side portion 22 is axially opposite to the drain hole 111. That is, in the first water-blocking structure 2, at least the axial side portion 22 is located above the drain hole 111 and is used to block water. The axial side portion 22 can be connected and fixed to the housing body 1 by the first peripheral side portion 21 fixed to the edge of the drain hole 111, so that the axial side portion 22 and the drain hole 111 are axially opposite each other. In this way, even if water from outside the rearview mirror enters the drain hole 111 upwards (e.g., sprayed upwards or splashed into the drain hole 111), at least most of the water will be directly blocked by the axial side portion 22 above the drain hole 111 and fall back to the outside through the drain hole 111. This can effectively prevent external water from splashing upwards or being sprayed into the electronic components inside the housing body 1 through the drain hole 111, improving the waterproofness of the rearview mirror, thereby improving the safety of the electronic components and ensuring their effectiveness.

[0033] In this embodiment, since the first peripheral side 21 is located at the edge of the drain hole 111, the first peripheral side 21 can avoid occupying the space of other positions inside the shell body 1, and the entire first water-blocking structure 2 has a high degree of integration and occupies little space, so that the first water-blocking structure 2 will not hinder the arrangement and installation of other parts inside the shell body 1.

[0034] See Figure 2 and Figure 4 The distance between the shaft side portion 22 and the drain hole 111 should not be too small or too large. If the distance between the shaft side portion 22 and the drain hole 111 is too small, it will affect the original water leakage function of the drain hole 111; if the distance between the shaft side portion 22 and the drain hole 111 is too large, that is, if the distance between the shaft side portion 22 and the bottom plate 11 of the shell body 1 is too large, it may affect the arrangement of the electronic components above and affect its water blocking effect.

[0035] See Figure 2 and Figure 4 Optionally, the first circumferential side portion 21 surrounds a portion of the drain hole 111 circumferentially; and / or, the dimensions of the axial side portion 22 match those of the drain hole 111.

[0036] In this embodiment, as mentioned above, one end of the first peripheral side portion 21 is specifically connected to the edge of the drain hole 111, and this end of the first peripheral side portion 21 is also its bottom end. Based on this, the first peripheral side portion 21 surrounds the drain hole 111 along the circumferential portion of the drain hole 111, for example, the first peripheral side portion 21 partially surrounds the drain hole 111, so that the first peripheral side portion 21 also has a water-blocking function.

[0037] Thus, if the external water is not, or not entirely, sprayed or splashed into the inside of the drain hole 111 in a vertical direction (the axial direction of the drain hole 111), that is, if there is water entering the drain hole 111 in an inclined direction, this inclined water can be directly blocked by the first peripheral side 21 and then flow out through the drain hole 111. By blocking water on the periphery of the drain hole 111 through the first peripheral side wall and blocking water on the axial side of the drain hole 111 (that is, blocking water on the upper side) through the axial side of the drain hole 111, the water-blocking effect of the first water-blocking structure 2 is improved.

[0038] Moreover, since the first peripheral side 21 located around the drain hole 111 does not completely surround the drain hole 111 in 360°, the part around the drain hole 111 that is not surrounded can allow water to flow, ensuring that water that seeps into the shell body 1 from other places can be naturally discharged through the drain hole 111 from this part, that is, ensuring the normal use of the original function of the drain hole 111.

[0039] Optionally, the first side portion 21 is located on the side of the drain hole 111 closer to the electronic components, so as to more effectively prevent water entering the drain hole 111 along the inclined direction from contacting the electronic components.

[0040] In this embodiment, the axial side portion 22 can be a plate-like structure, which is located directly above the drain hole 111. Its size and shape match the drain hole 111, that is, the shape and size are approximately the same, so as to ensure its effectiveness in blocking water.

[0041] See Figure 2 Optionally, the axial side portion 22, the first peripheral side portion 21, and the shell body 1 are integrally formed structures.

[0042] In this embodiment, the axle side portion 22, the first peripheral side portion 21, and the shell body 1 are preferably integrally formed. That is, the first peripheral side portion 21 and the axle side portion 22 are integrally formed at the same time as the shell body 1 is formed. This reduces the number of molds required, improves production efficiency, and saves costs. Furthermore, since the axle side portion 22, the first peripheral side portion 21, and the shell body 1 are integrally formed, the structural strength of the first water-blocking structure 2 can be guaranteed, preventing the first water-blocking structure 2 from shaking, misaligning, or even falling off due to vehicle vibration. Similar to related technologies, a protruding post 112 can be provided on the bottom plate 11 of the shell body 1. The protruding post 112 has bolt holes for bolting electronic components such as those inside the exterior rearview mirror. In this embodiment, the first water-blocking structure 2 can also be connected to the protruding post 112 and integrally formed, thereby enhancing the structural strength of the first water-blocking structure 2.

[0043] In this embodiment, the size of the shaft side portion 22 matches the size of the water leakage hole 111. Specifically, the size of the shaft side portion 22 is equal to or slightly smaller than the size of the water leakage hole 111. In this case, the first water-blocking structure 2 and the shell body 1 with the water leakage hole 111 are integrally formed, which facilitates demolding.

[0044] See Figure 1-4 Optionally, the shell body 1 includes a bottom plate 11 and a side wall portion 12. The bottom plate 11 has an upwardly bent side wall portion 12 at at least a portion of its edge. The drain hole 111 is located on the bottom plate 11 adjacent to the side wall portion 12. The first peripheral side portion 21 is located on the side of the drain hole 111 away from the side wall portion 12.

[0045] In this embodiment, the shell body 1 specifically refers to the lower shell of the exterior rearview mirror, which is used to splice with the upper shell of the exterior rearview mirror (not shown in the figure) to form a shell assembly. In this lower shell, in order to facilitate docking with the upper shell, at least a portion of the edge of the bottom plate 11 of the lower shell is bent upward to form a side wall portion 12, so that the lower shell can dock with the upper shell through the side wall portion 12.

[0046] In this embodiment, the drain hole 111 is located on the bottom plate 11 of the lower housing near the side wall portion 12. In this case, the first peripheral side portion 21 partially surrounds the drain hole 111 away from the side wall portion 12, that is, the first peripheral side portion 21 is located on one edge of the drain hole 111 near the center of the bottom plate 11. Thus, assuming that external water enters the drain hole 111 in an inclined direction (at an angle with the axis of the drain hole 111), even if it is not blocked by the first peripheral side portion 21 and the axial side portion 22 (the inclined direction is, for example, ), Figure 4 The direction indicated by the dashed arrow is basically splashed or sprayed onto the side wall 12 of the shell body 1. Water entering from this direction will not cause the electronic components to get wet. Secondly, after the water splashes or sprays onto the side wall 12 along this inclined direction, it will flow back down along the bending direction of the side wall 12 and finally flow out from the drain hole 111.

[0047] See Figure 5 Optionally, the exterior rearview mirror housing also includes a second water-blocking structure 3, the second water-blocking structure 3 including a second peripheral side portion 31, the second peripheral side portion 31 being located at the edge of the water leakage hole 111, the second peripheral side portion 31 surrounding part of the water leakage hole 111 circumferentially, and a radial water flow channel 41 being formed between the second peripheral side portion 31 and the first peripheral side portion 21.

[0048] In this embodiment, the second water-blocking structure 3 includes a second peripheral side 31 opposite to the first peripheral side 21. The second peripheral side 31 also surrounds part of the water leakage hole 111. For example, the first peripheral side 21 surrounds the right edge of the water leakage hole 111, and the second peripheral side 31 surrounds the left edge of the water leakage hole 111. The first peripheral side 21 and the second peripheral side 31 are not closed, but form a radial water flow channel 41 between them.

[0049] The radial water flow channel 41 allows water that has seeped into the shell body 1 to drain naturally outward through the drain hole 111. The presence of the second peripheral side 31 ensures that even if external water is sprayed or splashed into the drain hole 111 along an inclined direction not obstructed by the first peripheral side 21 (this inclined direction is, for example, ...), the water flow channel 41 allows water that has seeped into the shell body 1 to drain naturally outward through the drain hole 111. Figure 4 (In the direction indicated by the dashed arrow), external water will also be basically blocked by the second side 31, further improving the water blocking effect around the drain hole 111.

[0050] See Figure 5 Optionally, the second water-blocking structure 3 further includes a third peripheral side portion 32, which is arranged around the water leakage hole 111 and corresponds to the position of the radial water flow channel 41. The inner diameter of the third peripheral side portion 32 is larger than the outer diameter of the first peripheral side portion 21 and the second peripheral side portion 31.

[0051] In this embodiment, the second water-blocking structure 3 also includes a third circumferential side portion 32 surrounding a portion of the water leakage hole 111. However, the inner diameter of the third circumferential side portion 32 is larger than the outer diameter of the first circumferential side portion 21 and the second circumferential side portion 31, and the third circumferential side portion 32 is located at the corresponding radial water flow channel 41. Thus, under the combined action of the third circumferential side portion 32, the second circumferential side portion 31 and the first circumferential side portion 21, a water-blocking effect can be achieved in all directions around the water leakage hole 111 at 360°, ensuring that no matter from which tilt direction external water is sprayed or splashed into the water leakage hole 111, it can be directly blocked.

[0052] In this embodiment, to ensure a 360° all-around water-blocking effect around the leakage hole 111, the third circumferential side 32 preferably overlaps with the first circumferential side 21, such as... Figure 5 As shown, when the third circumferential side 32 and the first circumferential side 21 have overlapping areas, a circumferential water flow channel 42 is formed between the third circumferential side 32 and the first circumferential side 21. The water flow channel formed by the circumferential water flow channel 42 and the radial water flow channel 41 allows water that has seeped into the shell body 1 to be naturally discharged outward through the drain hole 111.

[0053] See Figure 5 Optionally, the second water-blocking structure 3 further includes a connecting portion 33, wherein one end of the third peripheral side portion 32 near the second peripheral side portion 31 is connected to the second peripheral side portion 31 through the connecting portion 33.

[0054] In this embodiment, the third peripheral side 32 is connected to the second peripheral side 31 as a whole through the connecting part 33. Since the inner diameter of the third peripheral side 32 is larger than the outer diameter of the second peripheral side 31, the horizontal cross section of the connecting part 33 can extend radially along the water leakage hole 111. Since the connecting part 33 closes the gap between one end of the third peripheral side 32 and the second peripheral side 31, the water blocking effect can be further improved.

[0055] See Figure 5 Optionally, the outer wall of the first peripheral side 21 is provided with a groove 211, the groove 211 extends along the axial direction of the drain hole 111, and the end of the third peripheral side 32 away from the connecting part 33 is provided with a protrusion 321, the protrusion 321 slidingly engaging with the groove 211.

[0056] In this embodiment, unlike the first water-blocking structure 2 which is an integral structure with the shell body 1, the second water-blocking structure 3 can be an additional structure. It may not be directly connected to the shell body 1, but is connected to the first water-blocking structure 2 to ensure its position is fixed.

[0057] Specifically, a groove 211 is provided on the outer wall of the first peripheral side 21. The groove 211 extends upward through the first peripheral side 21 along its axial direction. Thus, when the first water-blocking structure 2 is installed, the protrusion 321 of the third peripheral side 32 can be inserted into the groove 211 in a downward direction until the bottom ends of the third peripheral side 32, the connecting part 33, and the second peripheral side 31 abut against the bottom plate 11 of the shell body 1.

[0058] It is understandable that when the bottom ends of the third circumferential side 32, the connecting part 33, and the second circumferential side 31 abut against the bottom plate 11 of the shell body 1, the protrusion 321 does not abut against the bottom plate 11 of the shell body 1. That is, there is a gap between the protrusion 321 and the bottom plate 11, which ensures that the water inside the shell body 1 can be discharged from the bottom of the protrusion 321 and the circumferential water flow channel 42 and the radial water flow channel 41 through the leakage hole 111. There is sliding damping between the protrusion 321 and the groove 211, which can prevent the second water-blocking structure 3 from moving upward when the vehicle vibrates.

[0059] Another embodiment of the present invention provides an exterior rearview mirror, including the exterior rearview mirror housing as described above.

[0060] Since the technical improvements and effects of the aforementioned exterior rearview mirror are at least the same as those of the exterior rearview mirror housing, the exterior rearview mirror will not be described in detail again.

[0061] Another embodiment of the present invention provides a vehicle including the exterior rearview mirror as described above.

[0064] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
