Description

Technical Field

[0001] This invention relates to the technical field of vehicle parts, and more specifically to a sun visor hook and a vehicle including the same. Background Technology

[0002] An airbag system is a passive safety protection system for vehicles. It works in conjunction with seat belts to provide effective collision protection for occupants. With the continuous development of automotive technology, passive safety technology has also advanced, and the placement of airbags has changed. For example, the overhead airbag module above the passenger side is specifically positioned between the overhead roof and the vehicle's body panels. When a collision occurs, the airbag inflates and expands forward, providing impact protection between the occupant and the front structure of the vehicle.

[0003] However, sun visors are also needed below the roof to shield occupants from sunlight and reduce glare. Occupants can rotate the sun visors up and down along the pivot fixed to the visor hooks or pull them out of the hooks and rotate them to the top of the side windows to block sunlight. When the roof airbag module inflates, it exerts a significant impact on the sun visors, making the hooks prone to breakage and detachment. Broken hooks are hard, flying debris that can injure occupants. This is because sun visor hooks are usually made of plastic, and even with conventional reinforcement structures, they are relatively fragile and cannot withstand the impact of airbag deployment. Therefore, it is necessary to propose a new type of sun visor hook to solve the above problems. Summary of the Invention

[0004] In view of the above problems, the present invention provides a sun visor hook and a vehicle including the same. By providing a metal insert inside the sun visor hook, the structural strength of the sun visor hook is enhanced and the service life of the sun visor hook is improved.

[0005] To this end, a first aspect of the present invention provides a sun visor hook, comprising a hook body formed of a plastic material and including a fixing portion for fixing to a vehicle roof and a hook portion extending from the fixing portion, the hook portion forming a receiving groove for supporting and holding a pivot of the sun visor; and a metal insert, at least a portion of which is embedded in the hook portion and configured to have a planar and / or curved shape conforming to the hook portion.

[0006] Based on the above-described technical concept, the present invention may further include any one or more of the following optional forms.

[0007] In some alternative forms, the metal insert includes a flat portion and an extension extending from the flat portion, the flat portion being at least partially embedded in the fixing portion, and the extension being embedded in the hook portion and not extending to the free end of the hook portion away from the fixing portion.

[0008] In some alternative configurations, the extension is positioned approximately centrally within the hook portion.

[0009] In some alternative forms, the flat portion includes an outer surface exposed relative to the fixing portion, and the outer surface of the flat portion is substantially flush with the outer surface of the fixing portion.

[0010] In some alternative forms, the metal insert includes a plurality of through holes that are generally evenly distributed on the extension to allow material of the hook body to pass through.

[0011] In some alternative forms, the sun visor hook further includes a metal elastic member fixed to the hook body, with an opening formed between the metal elastic member and the free end of the hook portion for allowing the pivot to enter or exit the receiving groove.

[0012] In some alternative configurations, the fastener is configured to be secured to the vehicle roof by screw connection and / or snap-fit.

[0013] In some alternative forms, the sun visor hook also includes a cover that is fixed to the hook body and at least partially covers the fixing portion.

[0014] In some alternative forms, the metal insert is configured as a thin sheet with a thickness of 0.5 mm to 3 mm.

[0015] A second aspect of the invention provides a vehicle including a roof, a sun visor, and a roof airbag, wherein the sun visor is fixed to the roof at least by a sun visor hook according to a first aspect of the invention, and the roof airbag is disposed on the side of the roof opposite to the sun visor.

[0016] Compared with the prior art, the application of the sun visor hook according to the present invention can produce several beneficial technical effects, especially: by setting a metal insert, at least a portion of the metal insert is embedded in the hook portion of the hook body, and the embedded portion of the metal insert can conform to the shape of the hook portion, thereby enhancing the structural strength of the sun visor hook, preventing the sun visor hook from breaking and flying off during the deployment of the roof airbag behind the vehicle roof, which would cause injury. At the same time, it can also improve the stability and reliability of the use of the sun visor hook and extend the service life of the sun visor. Attached Figure Description

[0027] The elements in the accompanying drawings are shown for simplicity and clarity and are not necessarily drawn to exact scale. It should be understood that these drawings are not only for explaining and illustrating the invention, but also, where necessary, for defining the invention. Detailed Implementation

[0028] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using the invention, and are not intended to limit the scope of the invention.

[0029] The directional and positional terms used in this invention can be referred to as follows: Figures 1 to 9 The exemplary structure shown is explained.

[0030] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0031] Figure 1This diagram illustrates the assembly of a sun visor applied to the vehicle roof. Figure 2 It shows in Figure 1 A cross-sectional view of the sun visor hook, as shown. Figure 1 and Figure 2 As shown, the roof 20 is mounted on the sheet metal 40. Sun visors 10, which can rotate up and down around a pivot 200, are arranged on the sides of the roof 20 facing the driver's seat and the front passenger seat, respectively. A roof airbag 30 is arranged on the side of the roof 20 away from the front passenger seat. When the vehicle is involved in a collision, the roof airbag 30 is deployed. It inflates and propels itself out from between the roof 20 and the sheet metal 40, extending forward along the windshield (not shown) to protect the front passenger occupant.

[0032] Figure 3 and Figure 4 These are schematic diagrams of the structure of a sunshade hook according to a different embodiment of the present invention. Figure 5 This is an exploded view of the sun visor hook. Figure 6 This is a cross-sectional view of the sun visor hook. (Example) Figures 3 to 6 As shown, the sun visor hook 100 mainly includes a hook body 110 and a metal insert 120. The hook body 110 includes a fixing portion 111 for fixing itself to the vehicle roof 20 and a hook portion 112 extending from the fixing portion 111. The hook portion 112 includes a structure forming a receiving groove 114 for supporting and holding the pivot 200 of the sun visor 10, and a transition structure extending from the fixing portion 111 to the above structure. At least a portion of the metal insert 120 is embedded in the hook portion 112, and the shape of the portion of the metal insert 120 embedded in the hook portion 112 is shaped to conform to the shape of the hook portion 112, forming a planar and / or curved shape. The material of the hook body 110 is a plastic material, such as PA6 (polyamide 6) or PA66 (polyamide 66) with good impact resistance, which can enhance the impact resistance of the sun visor hook 100. During the detonation test and simulation of the roof airbag 30, the breakage location of the sun visor hook 100 is usually the hook portion 112. By fitting at least a portion of the metal insert 120 into the hook portion 112, the structural strength of the hook body 110 can be further enhanced, the impact resistance of the sun visor hook 100 can be improved, and the damage to the hook body 110 caused by the roof airbag 30 breaking and splashing during the inflation process can be prevented. At the same time, the stability and reliability of the sun visor hook 100 can be improved, and the service life of the sun visor hook 100 can be extended.

[0033] In some embodiments, the fixing part 111 is fixed to the vehicle roof 20 by screw connection and / or snap-fit, for example Figure 5As shown, the sun visor hook 100 also includes a stud 150 and a clip 160. The fixing part 111 includes a push pin 117 directly injection molded to the hook body 110. The push pin 117, stud 150, and clip 160 work together to connect and fix the sun visor hook 100 to the vehicle's roof 20. Further, as... Figure 6 As shown, the sun visor hook 100 also includes a metal elastic element 140, which can be configured as a spring. The hook body 110 is injection molded to form an installation structure 118 for fixing the metal elastic element 140. An opening 116 is formed between the metal elastic element 140 and the free end 115 of the hook portion 112 for allowing the rotating shaft 200 to enter or leave the receiving groove 114. The hook portion 112 and the metal elastic element 140 work together to detachably engage the rotating shaft 200 of the sun visor 10.

[0034] Figure 7 A schematic diagram of the hook body 110 is shown. Figure 8 For along Figure 7 Cross-sectional view, such as Figure 7 and Figure 8 As shown, the metal insert 120 includes a flat portion 121 corresponding to the fixing portion 111 and an extension portion 122 corresponding to the hook portion 112, wherein the extension portion 122 extends from the flat portion 121. The shape of the flat portion 121 is adapted to the fixing portion 111, and the shape of the extension portion 122 is adapted to the hook portion 112. The flat portion 121 is at least partially embedded in the fixing portion 111, the extension portion 122 is embedded in the hook portion 112, and the metal insert 120 does not extend to the free end 115 of the hook portion 112 opposite to the fixing portion 111, that is, the metal insert 120 is not embedded in the free end 115 of the hook portion 112. Figure 3 As shown, the hook portion 112 and the metal elastic element 140 work together to engage the pivot 200 of the sun visor 10. However, in practical applications, users often need to pull the pivot 200 out of the sun visor hook 100 through the opening 116 and adjust the position of the sun visor 10 for sun shading. Therefore, the insertion and extraction force of the sun visor hook 100 needs to be controlled so that users can easily insert and remove the pivot 200 from the sun visor hook 100, while ensuring the structural strength of the sun visor hook 100 to prevent it from breaking and splashing. In the detonation test and simulation of the roof airbag 30, the free end 115 is not the weakest point of the sun visor hook 100. Therefore, there is no need to set the metal insert 120 in the free end 115 to prevent the structural strength of the free end 115 from being too large, increasing the insertion and extraction force, and making it difficult for users to operate.

[0035] In some embodiments, the metal insert 120 is fixed to the hook body 110 by an insert injection molding process. The metal insert 120 is a thin sheet with a thickness of 0.5 mm to 3 mm, such as 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm. The material selection for the metal insert 120 is relatively broad; most metals or metal alloys with good ductility can be used, such as common iron or steel. Further, as... Figure 7 As shown, the metal insert 120 includes a plurality of through holes 123 that are generally evenly distributed on the extension 122. Figure 7 One arrangement of the multiple through holes 123 is shown. These through holes 123 facilitate the flow of injection molding liquid during insert molding. The material of the hook body 110 can pass through the multiple through holes 123, making the connection between the metal insert 120 and the hook body 110 tighter and improving the connection stability. It is understood that the metal insert 120 is positioned approximately centrally within the hook portion 112 (e.g., in the thickness and width directions) to further enhance the structural strength of the sun visor hook 100. Continuing... Figure 6 The flat portion 121 includes an outer surface exposed relative to the fixing portion 111, and the outer surface of the flat portion 121 is substantially flush with the outer surface of the fixing portion 111. This facilitates the positioning of the metal insert 120 in the insert injection mold during the manufacturing of the sun visor hook 100. Furthermore, the flat portion 121 includes a plurality of positioning holes 124, which further assist in the positioning of the metal insert 120 in the insert injection mold.

[0036] Preferably, such as Figures 3 to 5 As shown, the sun visor hook 100 also includes a cover 130, which is fixedly connected to the hook body 110. The cover 130 is used to at least partially cover the fixing part 111, such as the pin 150 connected to the fixing part 111 and the exposed metal insert 120 on the fixing part 111, and to beautify the shape of the sun visor hook 100 and enhance the overall shape of the sun visor 10.

[0037] In some embodiments, the present invention also provides a vehicle including a roof 20, a sun visor 10, and a roof airbag 30. The sun visor 10 is fixed to the roof 20 by the aforementioned sun visor hook 100 and other fasteners (e.g., fastener 300). The roof airbag 30 is disposed on the side of the roof 20 opposite to the sun visor 10. The sun visor 10 can be rotated up and down around a pivot 200, or the pivot 200 can be pulled out from the sun visor hook 100 and rotated around the fastener 300 to the top of the vehicle's side window to accommodate blocking sunlight at different angles. By enhancing the structural strength of the sun visor hook 100, it is possible to prevent the roof airbag 30 behind the vehicle roof from collapsing during deployment, protecting vehicle passengers from flying debris from the sun visor hook 100, extending the service life of the sun visor hook, and improving the user experience. It is understandable that the airbag protecting the driver's seat is usually located inside the steering wheel. The sun visor hook 100 mentioned above can be applied only to the sun visor 10 on the passenger side, or it can be applied to the sun visors 10 on both the left and right sides for ease of assembly.

[0038] The technical content and features of the present invention have been disclosed above. However, it is understood that, under the creative concept of the present invention, those skilled in the art can combine different embodiments or examples described in the present invention with the features of different embodiments or examples, but all of them fall within the protection scope of the present invention.
