This application discloses an installation structure for a rearview mirror housing and an adjustment handle, a rearview mirror, and a vehicle. The installation structure includes an adjustment handle with a connecting portion having two snap-fit ​​ends. The rearview mirror housing includes two fixing portions with snap-fit ​​grooves at their ends. Each snap-fit ​​groove has a stress-relieving structure at its end. One snap-fit ​​end can engage with one of the snap-fit ​​grooves, and the other snap-fit ​​end can engage with the other snap-fit ​​groove, allowing the adjustment handle to rotate. By providing a stress-relieving structure at the end of the snap-fit ​​groove, when the snap-fit ​​end of the adjustment handle is forcibly pressed into the groove, it ensures that the handle will not come out during the pressing process. Simultaneously, the stress-relieving structure absorbs stress deformation without damaging the structure of the snap-fit ​​groove or the snap-fit ​​end, allowing the snap-fit ​​end to be smoothly installed in place.

Description

Technical Field

[0001] This application relates to the field of vehicle accessory structure technology, and in particular to a mounting structure for a rearview mirror housing and adjustment handle, a rearview mirror, and a vehicle. Background Technology

[0002] In the existing technology, the lens housing of frameless endoscopes is generally made of PC+ABS, which is a relatively hard plastic. The adjustment handle of the endoscope is made of POM material, which also has a certain degree of hardness. The groove on the lens housing that mates with the rotating shaft of the adjustment handle is circular, and the groove is greater than 1 / 2 arc. Therefore, the mounting shaft of the adjustment handle is forcibly pressed into the selection groove of the lens housing by a fixture. Since both the lens housing and the adjustment handle are made of hard plastic, the compressive stress during assembly will damage the shape of the rotating groove or crush the rotating shaft, resulting in functional failure or adjustment jamming.

[0026] This section will describe in detail the specific embodiments of this application. Preferred embodiments of this application are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of this application, but they should not be construed as limiting the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0029] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0030] Reference Figure 1 This application provides a mounting structure for a rearview mirror housing and an adjustment handle, including an adjustment handle 200 and a rearview mirror housing 100.

[0031] like Figure 2As shown, the adjustment handle 200 includes a connecting part, which is disposed at one end of the adjustment handle 200. The connecting part is provided with two snap-fit ​​ends 210, which are symmetrically disposed on both sides of the snap-fit ​​ends 210.

[0032] like Figure 2 and Figure 3 As shown, the rearview mirror housing 100 includes two fixing parts 110. The fixing parts 110 are provided with snap-fit ​​grooves 120. The ends of the snap-fit ​​grooves 120 are provided with stress-relieving structures. One snap-fit ​​end 210 can be snapped into one of the snap-fit ​​grooves 120, and the other snap-fit ​​end 210 can be snapped into the other snap-fit ​​groove 120, so that the adjustment handle 200 can rotate.

[0033] In the prior art, a snap-fit ​​groove 120 is usually provided on the fixing part 110. One end of the snap-fit ​​groove 120 is open, and the other end is provided with a reinforcing rib so that the snap-fit ​​groove 120 can be restored to snap the snap-fit ​​end 210 during the snap-fit ​​process. However, the setting of the reinforcing rib will increase the difficulty of the snap-fit ​​end 210 entering, and will also easily cause hard snap-fit ​​damage to the snap-fit ​​groove 120.

[0034] This application provides a stress-relief structure at the end (i.e., the reinforcing rib) of the snap-fit ​​groove 120. When the snap-fit ​​end 210 of the adjusting handle 200 is forcibly pressed into the snap-fit ​​groove 120, it can ensure that the handle will not come out during the pressing process. At the same time, the snap-fit ​​groove 120 is installed smoothly without damaging the structure of the snap-fit ​​groove 120 or the snap-fit ​​end 210 under the stress-relief structure's absorption of stress deformation.

[0035] In some embodiments shown in this application, the cross-sectional shape of the bottom of the snap-fit ​​groove 120 is arc-shaped, and the ratio of the arc length to the arc length of a full circle of the same diameter is greater than 0.5. This facilitates the snap-fit ​​end 210 to enter from the groove opening and also facilitates the snap-fit ​​connection by confining the snap-fit ​​end 210 within the snap-fit ​​groove 120 through the snap-fit ​​structure.

[0036] like Figures 2 to 5 As shown, the snap-fit ​​end 210 is a cylindrical structure adapted to the snap-fit ​​groove 120. The snap-fit ​​end 210 and the snap-fit ​​groove 120 are in clearance fit. The two sides of the groove opening of the snap-fit ​​groove 120 are provided with second inclined surfaces 121. Both second inclined surfaces 121 are inclined outward to form a funnel-shaped guide structure. The second inclined surfaces 121 facilitate the guidance of the snap-fit ​​end 210 to the snap-fit ​​groove 120, which enables the assembly to be carried out in a more labor-saving manner during the snap-fit ​​process, thereby improving the assembly efficiency.

[0037] In some embodiments, the stress-relieving structure is a stress-relieving groove 130, the groove opening of which is oriented in the same direction as the opening of the snap-fit ​​groove 120. The stress-relieving groove 130 reduces the difficulty of deformation of the snap-fit ​​groove 120, making it easier for the snap-fit ​​end 210 to snap into the snap-fit ​​groove 120, and also avoids damage to the snap-fit ​​groove 120 or the snap-fit ​​end 210 during the snap-fit ​​process.

[0038] In some embodiments, the cross-sectional shape of the bottom of the stress relief groove 130 is an arc. The arc-shaped bottom of the groove allows the snap-fit ​​end 210 to absorb stress deformation during the snap-fit ​​groove 120 without damaging the structure of the snap-fit ​​groove 120 or the snap-fit ​​end 210, facilitating the quick installation of the snap-fit ​​end 210 and the snap-fit ​​groove 120.

[0039] In this embodiment, the ratio of the arc length to the arc length of a complete circle of the same diameter is greater than 0.5. This structure can improve the relatively stable force unloading effect and effectively protect the snap-fit ​​groove 120.

[0040] In some embodiments, a first inclined surface 131 is provided on both sides of the opening of the stress relief groove 130, and both first inclined surfaces 131 are inclined outward. The first inclined surface 131, together with the arc-shaped bottom of the groove, makes the engagement between the locking groove 120 and the locking end 210 smoother, and after the engagement is completed, the locking groove 120 can also stably restrict the disengagement of the locking end 210.

[0041] In some specific embodiments, the diameter of the arc is greater than 1 mm, but the diameter of the arc is smaller than the bottom width of the snap-fit ​​groove 120. This ensures stress relief while also protecting the snap-fit ​​groove 120.

[0042] In some specific embodiments, the groove width of the stress relief groove 130 is greater than 0.2 mm, wherein the groove width of the stress relief groove 130 is smaller than the diameter of the arc. The width of the stress relief groove 130 should not be set too large, as an excessively large width may result in insufficient clamping force of the locking groove 120.

[0043] In some specific embodiments, such as Figure 5 As shown, the ratio of the depth of the stress relief groove 130 to the depth of the locking groove 120 is less than 0.5. The depth of the stress relief groove 130 should be shallower than the depth of the locking groove 120 to avoid damaging the locking force of the locking groove 120.

[0044] This application embodiment also provides a rearview mirror, which includes the above-described mounting structure of the rearview mirror housing and the adjustment handle.

[0045] This application also provides a vehicle including the aforementioned rearview mirror.

[0046] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
