Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts technology, and in particular to an electrically folding rearview mirror bracket. Background Technology
[0002] Power folding side mirrors offer numerous advantages, including reduced risk of scratches, improved vehicle maneuverability, and intelligent operation, making them a standard feature on many car models. However, compared to traditional side mirrors, power folding mirrors require more attention to issues such as water ingress, dust accumulation, and debris entering through gaps. If there is too much debris in the gaps, the motor may be damaged due to excessive resistance when folding the mirror.
[0003] Current power folding rearview mirrors generally increase sealing by adding gaskets / rings to reduce damage caused by water accumulation. However, they require frequent maintenance from users to remove debris such as fallen leaves and dust. In winter, snow accumulation can also increase resistance to folding the mirror if it is not cleared in time. Summary of the Invention

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0028] Reference Figures 1 to 6 This application proposes an electrically folding rearview mirror bracket, including a mounting part 4. The mounting part 4 is recessed from the top surface to form a support area 6. The support area 6 includes a bottom surface and an arc-shaped side wall. A mounting shaft 5 is provided on the bottom surface of the support area 6. A connecting plate 9 is fixedly provided on the bottom of the rearview mirror 2. The connecting plate 9 is mounted on the support area 6 via the mounting shaft 5. The rearview mirror 2 preferably uses electric folding, generally via... Figure 1 The small window 1 on the door sheet metal 3 shown allows the driver to see the road conditions on the side and behind the vehicle.
[0029] like Figure 1As shown, an arc-shaped gap 13 is formed between the sidewall of the support area 6 and the sidewall of the connecting plate 9. The connecting plate 9 is a common structure for mounting the rearview mirror 2; it can be integrated with the rearview mirror 2 or detachably mounted. It is generally circular or arc-shaped or fan-shaped at the mounting point of the mounting part 4. The support area 6 also generally has arc-shaped sidewalls. This ensures that the arc-shaped sidewalls of the connecting plate 9 and the support area 6 do not interfere when the rearview mirror 2 rotates. Based on an understanding of the prior art, when the support area 6 and the connecting plate 9 are installed and form an arc-shaped gap 13, an arc-shaped fit between the connecting plate 9 and the support area 6 can be achieved. A clearing assembly is provided between the mounting part 4 and the connecting plate 9. The clearing assembly and the connecting plate 9 rotate synchronously, allowing the clearing assembly to scrape the arc-shaped gap 13. Figure 1 The bracket shown is a common type of electrically folding rearview mirror 2 bracket. A drawback of this type of bracket is that the gap between the connecting plate 9 and the mounting part 4 is exposed. When parked under a tree or in rainy or snowy weather, leaves, fruit, or debris such as rain and snow can easily get into this gap. If not cleaned regularly, this may obstruct or even damage the normal folding of the rearview mirror 2. Therefore, this embodiment adds a clearing component to this arc-shaped area. When the rearview mirror 2 is unfolded or folded, the clearing component can rotate synchronously, thus cleaning the interior of the arc-shaped gap 13 to a certain extent. Specific objects to be cleaned include fallen leaves, rain, and snow.
[0030] like Figure 2 As shown, the preferred obstacle removal component includes a scraper 8 disposed on the side wall of the connecting plate 9. The scraper 8 is positioned within the arc-shaped gap 13 throughout the entire folding and rotation range of the rearview mirror 2. The shape of the scraper 8 is not specifically limited here. When removing common debris such as leaves, the scraper 8 does not need to be specifically shaped. However, when removing debris such as snow, a relatively clean removal is generally required. Therefore, the scraper 8 may need to fit more closely to the arc-shaped gap 13 to achieve a better cleaning effect.
[0031] There is a gap between the scraper 8 and the arc-shaped gap 13 on the side wall of the mounting part 4. This gap is formed by the scraper 8 and the support area 6. Since the scraper 8 rotates during use, in order to reduce excessive wear between it and the mounting part 4, the scraper 8 and the side of the support area 6 do not directly contact each other. Thus, since the scraper 8 is not completely in contact, when cleaning rain and snow, rain and snow may be swept into the gap by the scraper 8. The snow will eventually melt into water. Therefore, the scraper 8 only needs to scrape the snow or scrape it into the gap. The snow accumulation will not cause excessive resistance when the rearview mirror 2 is folded. After the snow melts, it can flow out directly through the gap at the edge.
[0032] To facilitate the removal of impurities such as rain and snow in the above scheme, refer to Figure 3The obstacle clearing assembly also includes a downward-facing drainage channel 11 on the side wall of the support area 6. The depth of the drainage channel 11 gradually decreases towards the arc-shaped gap 13 (obviously, the drainage channel 11 extends from the bottom of the side wall of the support area 6 towards the arc-shaped gap 13) until it is level with the bottom surface of the support area 6. The depth of the drainage channel 11 gradually changes, connecting with the support area 6 and then gradually deepening. This is beneficial because when the scraper 8 removes rain and snow, the rain and snow can reach the bottom of the drainage channel 11 as much as possible, thus facilitating water drainage. On the other hand, the height of the drainage channel 11 can be gradually reduced from the middle to both sides, so that the height of the drainage channel 11 is lowest on both sides and highest in the middle, so that water flowing into the drainage channel 11 can be discharged as much as possible. This setting can reduce the impact of water and / or snow accumulating in the drainage channel 11 after the scraper 8 removes rain and snow in winter, and the risk of freezing due to low temperature. Of course, it is difficult to completely drain the accumulated water / snow using the scraper 8. Therefore, a heating component can be installed in the inner cavity of the mounting part 4 below the support area 6. The heating component is a component commonly used for defrosting / defogging the rearview mirror 2. This heating component can be installed in parallel inside the support area 6 to melt the snow by heating, thus facilitating its drainage.
[0033] Reference Figure 3 The obstacle clearing assembly also includes an arc-shaped cover plate 10 disposed on top of the support area 6. The bottom surface height of the arc-shaped cover plate 10 is equal to or greater than the top surface height of the connecting plate 9, and their projections on the horizontal plane overlap. The top projections of the arc-shaped cover plate 10 and the connecting plate 9 on the horizontal plane partially overlap. This arrangement allows the top of the arc-shaped gap to form a relatively closed space due to the action of the arc-shaped cover plate 10, making it difficult for solid impurities such as snow and leaves to enter the arc-shaped gap 13 and cause blockage. Preferably, the bottom surface of the arc-shaped cover plate 10 and the top surface of the connecting plate 9 are fitted together. When fitted together, the top sealing is increased, which helps to reduce the ingress of water.
[0034] Reference Figure 5 , Figure 6To ensure the cleaning effect of the scraper 8, gaps exist between the scraper 8 and the top of the connecting plate 9 on its upper and lower sides, and a gap 12 exists between the scraper 8 and the bottom surface of the support area 6. The height of the gap 12 is between 0.1mm and 1mm. Guide blocks 14 are provided on both sides of the scraper 8, with the thickness of the guide blocks 14 increasing from top to bottom. The gaps 12 on the upper and lower sides of the scraper 8 are designed to ensure that the scraper 8 can achieve a good cleaning effect on the entire area of the arc-shaped gap 13 when it moves, without directly acting on the connecting plate 9 and the mounting part 4, especially the area near the bottom surface of the connecting plate 9 and the support area 6. The height of the gap 12 is relatively small; if the height of the gap 12 is too large, the cleaning effect on the upper and lower sides of the arc-shaped gap 13 will be relatively poor. The function of the guide blocks 14 is to allow snow to slide down easily when scraping, for example, snow, thus preventing snow from adhering to the scraper 8.
[0035] Reference Figure 2 , Figure 4 The bottom surface of the support area 6 has a waterproof protrusion 7 on the outer side of the mounting shaft 5. The waterproof protrusion 7 increases in height from the outside to the inside to form a frustum-shaped cone. The bottom surface of the connecting plate 9 has a concave surface corresponding to the waterproof protrusion 7. Since the support area 6 is normally flat, water may accumulate at the joint after it connects with the connecting plate 9 of the rearview mirror 2 through gaps. In winter, if too much water accumulates, it will cause a thick layer of ice to form, which will greatly increase the resistance of the rearview mirror 2 and affect the normal use of the folding function of the rearview mirror 2. Therefore, in this embodiment, the joint is set as a cone, so that the water flow will generally not flow backward to the deeper part of the joint between the connecting plate 9 and the support area 6, thus reducing the occurrence of the above problems.
[0036] The mounting part 4 and the door sheet metal 3 are detachably fixed. The mounting shaft part 5 is connected to a motor in the inner cavity of the mounting part 4. The motor drives the rearview mirror 2 to fold automatically. The automatic folding of the rearview mirror 2 by the motor is a common technology in the field, so its specific structure and principle will not be described in detail.
[0037] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
