In this embodiment, the positioning post 25 is a cross-shaped rib structure with a guiding inclined surface at the top, and the connecting post 24 is a cylindrical screw post with reinforcing ribs; in other embodiments, the positioning post 25 and the connecting post 24 can also be other structures. It can be understood that the positioning post 25 can be provided on either the mounting base 11 or the decorative panel 2, and a positioning hole 113 is provided on the other; the connecting post 24 can be provided on either the mounting base 11 or the decorative panel 2, and a connecting hole 112 is provided on the other, and the connecting post 24 and the connecting hole 112 are connected and fixed by a screw.
[0035] Please continue to refer to Figure 5 As shown, after the mounting base 11 and the decorative panel 2 are installed and fixed, they are jointly assembled to the vehicle door sheet metal 3. The mounting base 11 can be a plastic part or a metal part such as aluminum alloy, etc., and the present application does not limit the material of the mounting base 11. Several screwing parts 111 are provided on the mounting base 11, and the mounting base 11 is threadedly locked and connected to the vehicle door sheet metal 3 through the screwing parts 111. In this embodiment, the screwing part 111 is a bolt post, and a bolt passes through the vehicle door sheet metal 3 and is locked on the screwing part 111.
[0036] Please refer to Figure 3 and Figure 4As shown, the decorative panel 2 is clamped and connected to the door sheet metal 3 through a plurality of snap portions. The decorative panel 2 has an exposed surface that is exposed to form a partial appearance surface of the external rearview mirror, and a mounting surface opposite to the exposed surface, and the snap portions are arranged on the mounting surface of the decorative panel 2. In this embodiment, the decorative panel 2 is snap-connected to the door sheet metal 3 in a relatively sliding manner. Specifically, the snap portion includes a sliding snap 21, and the sliding snap 21 passes through a snap hole 301 on the door sheet metal 3 and is clamped to the door sheet metal 3 after sliding relative to the door sheet metal 3. The snap hole 301 has a wide end with a larger opening size and a narrow end with a smaller opening size. The sliding snap 21 is inserted from the wide end of the snap hole 301 and slides to the narrow end to be clamped with the edge of the narrow end. The sliding snaps 21 are provided in plurality to achieve multiple clamping connections, increase the reliability of the connection, and prevent the decorative panel 2 from warping. In this embodiment, the number of the sliding snaps 21 is five. The specific structure of the sliding snap 21 can be diverse, such as Figure 3 As shown, it provides two structures of the sliding snap 21: one is a snap with a space in the middle and capable of elastic deformation, as shown in the enlarged view in the upper left corner of Figure 3 ; the other is a non-deformable clamping block structure of the snap, as shown in the enlarged view in the upper right corner of Figure 3 . In other embodiments, the specific structure of the sliding snap 21 can also be set with other deformations.
[0037] Please continue to refer to Figures 3 to 5 As shown, in this embodiment, the snap portion includes a limiting snap 22, and the limiting snap 22 protrudes into a limiting hole 302 on the door sheet metal 3 when the sliding snap 21 is clamped to the door sheet metal 3. Since in this embodiment, the decorative panel 2 is snap-connected to the door sheet metal 3 in a relatively sliding manner, when the sliding snap 21 is clamped to the door sheet metal 3 in place, the decorative panel 2 may slide in the direction opposite to the above-mentioned sliding installation direction under the action of gravity, thereby releasing the clamping. In this embodiment, by providing the limiting snap 22, when the sliding snap 21 is clamped to the door sheet metal 3, it forms an abutting limit with the door sheet metal 3 to prevent the decorative panel 2 from sliding in the reverse direction and releasing the clamping. The limiting snap 22 is an elastic cantilever-shaped snap. During the sliding installation process of the decorative panel 2 and the door sheet metal 3, the limiting snap 22 is squeezed and elastically deformed; when the sliding installation of the decorative panel 2 and the door sheet metal 3 is in place, the limiting snap 22 just slides to a position opposite to the limiting hole 302, and the limiting snap 22 is snapped into the limiting hole 302 under the action of elastic force to achieve limiting. After the decorative panel 2 is installed on the door sheet metal 3 through the snap portion, bolts are used to lock the door sheet metal 3 and the mounting base 11, that is, the installation between the external rearview mirror and the door sheet metal 3 is realized.
[0038] Please refer to Figure 5 As shown, in this embodiment, a plurality of seals are provided between the exterior rearview mirror and the vehicle door sheet metal 3 to form multiple seals. A main seal 4 is provided on the mounting base 11, and a plurality of sub-seals 5 are provided on the decorative panel 2. Among them, the main seal 4 is a sealing sheet that covers the mounting base 11. The main seal 4 adopts a sealing sheet, which has a large sealing range and can seal various holes in the covered area. In this embodiment, the sub-seal 5 includes a plurality of sealing rings 51 surrounding the buckle portion and a sealing strip 52 extending along the edge of the decorative panel 2. The sealing ring 51 can be a circular ring or a rectangular ring, and each sealing ring 51 can surround the periphery of one buckle portion. When there are multiple adjacent buckle portions, one sealing ring 51 can also surround the peripheries of multiple buckle portions at the same time. The sealing strip 52 is mainly used to achieve the sealed connection at the edge of the decorative panel 2. It can be arranged in a closed ring shape, or in a single extended strip shape, or in a semi-closed shape; in this embodiment, the sealing strip 52 is generally in a "C" shape.
[0039] The seals can be installed on the mounting base 11 and the decorative panel 2 by means of pasting, snap connection, screw connection, interference fit with a groove, etc. In this embodiment, the sub-seal 5 is adhesively bonded to the decorative panel 2 by pasting, and the main seal 4 is assembled on the mounting base 11 through a convex and concave structure. After the exterior rearview mirror and the vehicle door sheet metal 3 are assembled, both the main seal 4 and the sub-seal 5 are extruded and deformed to form a seal. The main seal 4 and the sub-seal 5 can be made of common sealing materials such as rubber and foam.
[0040] During assembly, first install the mounting base 11 and the decorative panel 2. The alignment is achieved through the cooperation of the positioning post 25 and the positioning hole 113, and the mounting base 11 and the decorative panel 2 are connected and fixed by screwing through the connecting hole 112 and locking it on the connecting post 24; then install the main seal 4 onto the mounting base 11, and the sub-seal 5 can be pre-set on the decorative panel 2; then install the decorative panel 2 and the mounting base 11 towards the vehicle door sheet metal 3, so that the sliding buckle 21 on the decorative panel 2 is inserted into the buckle hole 301 on the vehicle door sheet metal 3; push the decorative panel 2 upward so that the sliding buckle 21 slides and engages with the vehicle door sheet metal 3 until the limit buckle 22 snaps into the limit hole 302 under the action of elastic force to achieve limiting; finally, pass a bolt through the vehicle door sheet metal 3 and the main seal 4 and lock it on the screwing portion 111 of the mounting base 11 to complete the assembly.
[0041] As can be seen from the above description of the specific embodiments, the external rearview mirror provided by the present application includes a mounting base 11 and a decorative panel 2. The mounting base 11 is threadedly and tightly connected to the vehicle door sheet metal 3 through a screwing portion 111, and the decorative panel 2 is snap-connected to the vehicle door sheet metal 3 through a plurality of snap portions, realizing a reliable connection between the decorative panel 2 and the vehicle door sheet metal 3 and preventing the decorative panel 2 from warping and deforming. In the present application, a main seal 4 is provided on the mounting base 11, and a plurality of sub-seals 5 are provided on the decorative panel 2. The plurality of sub-seals 5 are arranged around the plurality of snap portions. When the external rearview mirror is mounted on the vehicle door sheet metal 3, the main seal 4 is pressed between the mounting base 11 and the vehicle door sheet metal 3, and the plurality of sub-seals 5 are pressed between the decorative panel 2 and the vehicle door sheet metal 3, so as to form a sealed connection at the mounting base 11 and around the plurality of snap portions, that is, by adding multiple independent seals, an effective waterproof and wind noise reduction effect is achieved. The present application also provides an installation structure of an external rearview mirror, which includes a vehicle door sheet metal 3 and the external rearview mirror as described above.
[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
