[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] Example 1

[0043] This embodiment relates to a car sun visor mounting structure, which can solve the problem of friction and abnormal noise between the hook 1 and the top cover sheet metal 3 or the top cover interior panel 2.

[0044] In terms of overall structure, Figures 3 to 11 As shown, the automobile sun visor mounting structure of this embodiment includes a hook assembly disposed on the vehicle roof. The hook assembly includes a hook 1 and an elastic buffer component 4 that is clamped to the hook 1. The hook 1 passes through the roof interior panel 2 and is connected to the roof sheet metal 3. The elastic buffer component 4 is located between the roof sheet metal 3 and the roof interior panel 2. The elastic buffer component 4 includes a base plate 401 and an elastic unit disposed on the base plate 401. The elastic unit abuts between the base plate 401 and the roof sheet metal 3, or alternatively, between the base plate 401 and the roof interior panel 2.

[0045] At this time, as set above, the elastic buffer component 4 is located between the top cover sheet metal 3 and the top cover interior panel 2, which can prevent the hook assembly, the top cover sheet metal 3 and the top cover interior panel 2 from colliding or rubbing during the driving of the vehicle. Moreover, through the contact between the elastic buffer component 4 and the top cover sheet metal 3 and the top cover interior panel 2, the elastic buffer component 4 will undergo elastic deformation to slow down and avoid friction with the above-mentioned components, thereby not generating abnormal friction noise, improving the refined perception of driving in the car, and thus improving the quality of the vehicle.

[0046] Based on the above overall introduction, in detail, in this embodiment, during the specific implementation, the top cover sheet metal 3 is provided with a sheet metal bracket, and the hook 1 is connected to the sheet metal bracket on the top cover sheet metal 3 after passing through the top cover interior panel 2. After passing through the top cover interior panel 2, the hook 1 is clamped with the elastic buffer component 4 between the top cover sheet metal 3 and the top cover interior panel 2. In this way, the hook 1 can be fixed on the top cover interior panel 2 to ensure that the sun visor is more stable during use, and when the top cover interior panel 2 is installed on the top cover sheet metal 3, the operator does not need to support the hook 1, which facilitates the subsequent installation of the hook 1.

[0047] Among them, the elastic buffer component 4 is snap-connected with the hook 1, so that the elastic buffer component 4 can be quickly installed on the hook 1 without the aid of complex tools, which facilitates installation and improves installation efficiency. The elastic buffer component 4 includes a substrate 401 and an elastic unit on the substrate 401, and has a simple structure and is easy to produce.

[0048] Furthermore, in this embodiment, the roof interior panel 2 is provided with a through-hole, and the roof sheet metal 3 is provided with a sheet metal bracket. The hook 1 passes through the through-hole and is specifically connected to the sheet metal bracket to complete the installation of the hook 1 on the roof assembly. Furthermore, any structural components of the hook 1 not described in this embodiment can refer to the structure of the hook 1 well known to those skilled in the art. For example, the hook 1 also includes a hanging hook and a retaining spring for mounting the sun visor, and these will not be described in detail here.

[0049] In this embodiment, as a preferred implementation form, see Figure 4 As shown, a through hole 402 is provided in the middle of the substrate 401 , and a plurality of snap-in units 404 extending into the through hole 402 are provided on the substrate 401 . A plurality of snap-in slots 101 are provided on the hook 1 , and each snap-in unit 404 is snapped into each snap-in slot 101 one by one.

[0050] During specific implementation, after the hook 1 passes through the through hole 402, the multiple snap-in units 404 on the base plate 401 will first press against the outer surface of the hook 1 and undergo elastic deformation until the snap-in units 404 are snapped into the corresponding multiple snap-in slots 101 on the hook 1, and then the stress will be released and the shape will be restored. At this time, after the snap-in units 404 are reset, they will tightly clamp the snap-in slots 101 on the hook 1 to form a stable locking state, making the connection between the hook 1 and the base plate 401 more stable, and the hook 1 and the top cover interior panel 2 will not fall off when the vehicle is driving or the top cover interior panel 2 is installed, and the fixing effect is good.

[0051] In addition, in this embodiment, as a preferred implementation form, see Figure 4 As shown, there are multiple elastic units arranged at intervals around the substrate 401. The elastic units include an elongated elastic piece 403. Both ends of the elastic piece 403 are connected to the substrate 401, and the middle of the elastic piece 403 arches toward one side of the substrate 401.

[0052] The elastic units are spaced circumferentially around the base plate 401 to ensure a more uniform stress distribution within the elastic buffer component 4 when subjected to force, preventing deformation or damage to a single point on the base plate 401 from being subjected to excessive stress. Furthermore, the middle portion of the elastic sheet 403 arches outward toward one side of the base plate 401, forming an arched structure. This arched structure deforms when subjected to external force, absorbing the energy of the external force. Once the external force disappears, it quickly returns to its original arched state and releases the absorbed energy. Thus, the elastic sheet 403 acts as an elastic buffer.

[0053] It should be noted that, in this embodiment, as a preferred implementation form, see Figures 8 to 10 As shown, the hook 1 is connected to the top cover sheet metal 3 through the connecting part 102. The connecting part 102 includes a base 1021 located on the hook 1, and a pre-installed structure provided on the base 1021. The pre-installed structure includes a plurality of pre-installed claws 1023 arranged at circumferential intervals around the base 1021. Each pre-installed claw 1023 is clamped in the clamping hole 301 on the top cover sheet metal 3.

[0054] A sheet metal bracket is provided on the roof sheet metal 3, and a snap-in hole 301 is provided on the sheet metal bracket. Multiple pre-installed claws 1023 snap into the snap-in hole 301, evenly distributing the connecting force between the hook 1 and the sheet metal bracket and ensuring a more stable connection. This ensures smoothness between the hook 1 and the roof interior panel 2, enhancing the cleanliness and aesthetics of the vehicle interior. Furthermore, the pre-installed claws 1023 can be used to locate the position of the hook 1 during installation, facilitating subsequent secure connection between the hook 1 and the roof sheet metal 3 and improving installation efficiency.

[0055] Furthermore, in this embodiment, as a preferred implementation form, see Figure 3 and Figure 10 As shown, base 1021 is connected to roof sheet metal 3 via a screw connection 5. This screw connection 5 secures base 1021 to the sheet metal bracket of roof sheet metal 3, providing a strong connection. Furthermore, the screw connection 5 is simple, making it easy for operators to assemble. Furthermore, the self-locking nut 502 and self-locking bolt 501 are self-locking, ensuring that the connection between hook 1 and the sheet metal bracket will not loosen, further enhancing connection reliability. While the vehicle is in motion, the screwed hook 1 and the sheet metal bracket remain relatively fixed, preventing friction between them and avoiding unusual noise, thereby enhancing the refined driving experience within the vehicle.

[0056] It is worth mentioning that, in this embodiment, as a preferred implementation form, see Figure 3As shown, the screw connection structure 5 includes a self-tightening nut 502 and a self-tightening bolt 501. The self-tightening nut 502 is located on the side of the top cover sheet metal 3 facing away from the hook 1. The self-tightening bolt 501 passes through the base 1021 and the top cover interior panel 2 in sequence and is screwed into the self-tightening nut 502.

[0057] Specifically, the self-tightening nut 502 is located on the side of the sheet metal bracket facing away from the hook 1. After the pre-installed claw 1023 is clamped into the clamping hole 301 on the top cover sheet metal 3, the operator tightens the self-tightening bolt 501, so that the self-tightening nut 502 moves toward the base 1021, and then the self-tightening nut 502 cooperates with the base 1021. During the tightening process of the self-tightening bolt, a greater clamping force will gradually be generated between the self-tightening nut 502 and the base 1021, thereby clamping the sheet metal bracket between the self-tightening nut 502 and the base 1021, thereby playing the role of stabilizing the connection between the hook 1 and the sheet metal bracket.

[0058] And, in this embodiment, as a preferred implementation form, see Figure 3 As shown, the self-tightening nut 502 is provided with a plurality of limiting protrusions 503 spaced along its circumference, and the top cover sheet metal 3 is provided with a plurality of retaining grooves 302, with each limiting protrusion 503 correspondingly engaging with each retaining groove 302. The sheet metal bracket on the top cover sheet metal 3 has a plurality of retaining grooves 302. When the self-tightening bolt 501 is rotated, the self-tightening nut 502 descends with the self-tightening bolt 501, thereby causing the plurality of limiting protrusions 503 on the self-tightening nut 502 to engage with each retaining groove 302 in a one-to-one manner. The limiting protrusions 503 on the self-tightening nut 502 effectively secure the sheet metal bracket.

[0059] In addition, in this embodiment, as a preferred implementation form, see Figure 3 As shown, a plurality of limiting guide grooves 1022 are provided on the base 1021, and each limiting protrusion 503 is arranged in a one-to-one correspondence with each limiting guide groove 1022, and as the self-tightening bolt 501 and the self-tightening nut 502 rotate relative to each other, each limiting protrusion 503 is guided by the corresponding limiting guide groove 1022 and is clamped into the corresponding clamping groove 302.

[0060] When the locking nut 502 is unlocked, the locking nut 503 is unlocked, and the locking nut 502 is unlocked.

[0061] The design of the limiting guide groove 1022 will limit the rotation of the limiting protrusion 503, so that when the self-tightening bolt 501 is tightened, the limiting guide groove 1022 prevents the limiting protrusion 503 from rotating, and the self-tightening nut 502 will not rotate. There is no need for the operator to additionally limit the self-tightening nut 502, which makes it easier for the operator to fix the hook 1 and improves installation efficiency.

[0062] Finally, in this embodiment, as a preferred implementation form, the elastic buffer component 4 is made of plastic and has good resilience, so that the elastic buffer component 4 can better protect the substrate, and the friction coefficient between the elastic buffer component 4 made of plastic and the sheet metal bracket or the top cover interior panel 2 is low, and no obvious friction sound is generated, thereby improving the exquisite driving perception in the car, and the elastic buffer component 4 is integrally formed, so that the elastic buffer component 4 can evenly distribute stress when subjected to force, reduce local stress concentration, and extend the service life of the elastic buffer component 4.

[0063] The specific installation process of the hook 1 is as follows: first, the hook 1 is passed through the top cover interior panel 2, and then the through hole 402 of the base plate 401 is placed on the outside of the hook 1, and the base plate 401 is pressed downward until the clamping unit 404 on the base plate 401 is clamped into the clamping groove 101 on the hook 1, and the hook 1 is clamped on the top cover interior panel 2. Secondly, the top cover interior panel 2 is assembled to the top cover sheet metal 3 of the car. At the same time, the pre-installed clamping claw 1023 on the hook 1 corresponds to the clamping hole 301 on the sheet metal bracket. The operator only needs to push the hook 1 upward to make the pre-installed clamping claw 1023 clamped into the clamping hole 301 to complete the positioning of the hook 1. Finally, by rotating the self-tightening bolt 501, the self-tightening nut 502 moves downward under the guidance of the limiting guide groove 1022 until the limiting protrusion 503 on the self-tightening nut is clamped in the clamping groove 302 to complete the positioning of the hook 1.

[0064] During the installation process, the operator can operate on one side of the roof interior panel 2. When using tools to install the self-tightening bolts, the operator does not need to limit the self-tightening nuts, which makes the operation more convenient and improves the installation efficiency. After the installation is completed, the elastic buffer component 4 on the hook 1 will not produce friction noise with the sheet metal bracket or the roof interior panel 2. Compared with the traditional sun visor installation structure, the elastic deformation of the elastic buffer component 4 can be used to avoid collision or friction between the roof sheet metal 3, the roof interior panel 2 and the hook assembly during vehicle driving, so as to reduce the risk of friction noise and avoid affecting the exquisite driving experience in the car.
