[0026] Schematic diagram of the snap-in structure of the automobile sun visor frame assembly.

[0027] refer to Figures 1 to 7 According to a preferred embodiment of the utility model, a snap-on structure of a car sun visor frame assembly includes a frame assembly, and the frame assembly includes a mirror frame 10 and a main frame 20.

[0028] Specifically, Figure 3 As shown, the mirror frame 10 has a plurality of first clamping protrusions 101 arranged in a ring shape on one side close to the main frame 20, and each of the first clamping protrusions 101 includes a protrusion body 1011, a first hook portion 1012 and a second hook portion 1013. One end of the protrusion body 1011 is connected to the mirror frame 10, and the other end of the protrusion body 1011 is respectively connected to the first hook portion 1012 and the second hook portion 1013, and the connection method includes but is not limited to one-piece injection molding. The first hook portion 1012 and the second hook portion 1013 are respectively located on both sides of the protrusion body 1011 and face opposite directions, and the first hook portion 1012 and the second hook portion 1013 both have a first guide slope 10121.

[0029] In addition, if Figure 4 As shown, the main frame 20 includes a plurality of first card slots 201 arranged in a ring shape, each of the first card slots 201 has a first abutment portion 2011 and a second abutment portion 2012, the first abutment portion 2011 and the second abutment portion 2012 are arranged relative to each other and spaced a predetermined distance apart, one side of the first abutment portion 2011 and the second abutment portion 2012 has a second guide slope 20111, the distance from the end of the first abutment portion 2011 to the end of the second abutment portion 2012 is smaller than the maximum distance between the first hook portion 1012 and the second hook portion 1013, when the first hook portion 1012 contacts the first abutment portion 2011, each of the first guide slopes 10121 is fitted with the corresponding second guide slope 20111, and the first abutment portion 2011 and the second abutment portion 2012 are both made of plastic.

[0030] It should be noted that, when the mirror frame 10 is connected to the main frame 20, each of the first clamping protrusions 101 is aligned with the corresponding first clamping grooves 201, and the end of the mirror frame 10 having the first clamping protrusion 101 gradually approaches the main frame 20. At a certain moment, the first guiding inclined surface 10121 on the first curved hook portion 1012 abuts against the second guiding inclined surface 20111 on the first abutting portion 2011, and the first guiding inclined surface 10121 on the second curved hook portion 1013 abuts against the second guiding inclined surface 20111 on the second abutting portion 2012. The two guiding slopes 20111 abut against each other, and the first hook portion 1012 and the second hook portion 1013 are respectively subjected to horizontal forces in opposite directions and move toward each other. The two horizontal forces cancel each other out, so that the first clamping protrusion 101 is still easy to maintain the state of being centered in the first clamping groove 201 through the first clamping groove 201, which effectively reduces the risk of the mirror frame 10 moving in the horizontal direction relative to the main frame 20 during the pressing process. Compared with the prior art, it has the advantages of better centering during the pressing process and can more stably clamp the mirror frame 10 with the main frame 20.

[0031] It should also be noted that if Figure 3 As shown, the first hook portion 1012 and the second hook portion 1013 have an anti-slip plane 10122 on one side of the hook away from the first guide slope 10121. When the first hook portion 1012 and the second hook portion 1013 pass through the first abutting portion 2011 and the second abutting portion 2012 on one side having the second guide slope 20111, the first hook portion 1012 and the second hook portion 1013 move opposite to each other under the action of their own elastic force and restore the state before deformation, and the anti-slip plane 10122 on the first hook portion 1012 and the second hook portion 1013 abuts against the first abutting portion 2011 and the second abutting portion 2012. At this time, the maximum spacing between the first hook portion 1012 and the second hook portion 1013 is greater than the spacing from the end of the first abutting portion 2011 to the end of the second abutting portion 2012.

[0032] Furthermore, in order to enhance the stability during the pressing process, e.g. Figure 3 and Figure 4As shown, the second hook portion 1013 has a guide groove 10131, and the guide groove 10131 penetrates the second hook portion 1013 in the height direction of the protruding body 1011. The second abutting portion 2012 has a guide protrusion 20123 at one end close to the first abutting portion 2011. When the first hook portion 1012 passes through the area between the first abutting portion 2011 and the second abutting portion 2012 and hooks the first abutting portion 2011, the guide protrusion 20123 extends into the guide groove 10131.

[0033] It should be noted that, during the contact between the first guide bevel 10121 and the second guide bevel 20111, the guide protrusion 20123 is slidably disposed in the guide groove 10131. Since the guide grooves 10131 are provided on all four sides of the mirror frame 10, the risk of the mirror frame 10 moving in the horizontal direction relative to the main frame 20 during the pressing process is further reduced.

[0034] Further, in the embodiments of the present application, Figure 3 As shown, the height of the first hook portion 1012 is greater than the height of the second hook portion 1013 , and the length of the first abutting portion 2011 extending into the first slot 201 is less than the length of the second abutting portion 2012 extending into the first slot 201 .

[0035] Furthermore, if Figure 2 , Figure 3 As shown, the mirror frame 10 has a through slot 102. Figure 5 and Figure 6 As shown, the snap-on structure of the automobile sun visor frame assembly further includes a mirror support plate 30, the mirror support plate 30 is located at one end of the through slot 102 close to the main frame 20, the mirror support plate 30 includes a plurality of external card blocks 301 arranged in a ring shape, and each of the external card blocks 301 has a third guiding inclined surface 3011 at one end away from the main frame 20, as shown in FIG. Figure 3 As shown, the mirror frame 10 has a plurality of second clamping protrusions 103 arranged in a ring shape at one end close to the main frame 20, each of the second clamping protrusions 103 includes two relatively arranged third hook portions 1031, and the opposite ends of the two third hook portions 1031 have a fourth guide slope 1032, and a clamping cavity 1033 with an opening is provided between the two third hook portions 1031, and the extended clamping blocks 301 correspond one-to-one with the second clamping protrusions 103. When each of the extended clamping blocks 301 passes through between the two third hook portions 1031 of the corresponding second clamping protrusion 103, the extended clamping block 301 is clamped into the clamping cavity 1033.

[0036] It should be noted that, during assembly, the mirror support plate 30 is first engaged with the mirror frame 10, and then the mirror frame 10 is engaged with the main frame 20. When the mirror support plate 30 is engaged with the mirror frame 10, the extended card block 301 is opposite to the second engaging protrusion 103, and the extended card block 301 is located between the two third hook portions 1031. Then, the extended card block 301 is gradually approached to the second engaging protrusion 103, and at a certain moment, the third guide bevel 3011 contacts the fourth guide bevel 1032, and as the two third hook portions 1031 move away from each other, the extended card block 301 passes through the area between the two third hook portions 1031 and enters the card cavity 1033.

[0037] Furthermore, in order to avoid the third hook portion 1031 interfering with the movement of the main frame 20 when the mirror frame 10 with the mirror support plate 30 is clamped with the main frame 20, Figure 7 As shown, the main frame 20 has a plurality of avoidance holes 202 , and the avoidance holes 202 correspond to the second clamping protrusions 103 one by one. When the mirror frame 10 is connected to the main frame 20 , each of the second clamping protrusions 103 passes through the corresponding avoidance hole 202 .

[0038] In summary, the clip-on structure of the automobile sun visor frame assembly based on the embodiment of the present application is clarified, which provides the clip-on structure of the automobile sun visor frame assembly with advantages such as better centering during the pressing process.

[0039] It is worth mentioning that in the embodiment of the present application, the structure of the snap-in structure of the automobile sun visor frame assembly is simple, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the snap-in structure of the automobile sun visor frame assembly provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
