DETAILED DESCRIPTION

[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0040] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, top, and bottom" are generally defined when the lock hook provided by the present disclosure is normally installed. Figure 3 In the drawing directions shown, "axial" and "radial" refer to the directions relative to the central axis of the fixing seat, and "inner" and "outer" refer to the inner and outer sides of the corresponding component contours. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first", "second", etc. used in this disclosure are to distinguish one element from another and have no order or importance.

[0041] like Figures 1 to 10As shown, the present disclosure provides a hook 1, which includes a hook body 11 and a fixing seat 12. The hook body 11 has a main body 110, a connecting portion 112 and a hook-shaped portion 111 for carrying articles. The connecting portion 112 and the hook-shaped portion 111 are respectively arranged on the upper and lower sides of the main body 110; the fixing seat 12 is connected to the hook body 11, and the fixing seat 12 is used to install the hook body 11 at a predetermined position; Figure 3 and Figure 5 As shown, the connecting portion 112 can extend into the inner cavity of the fixing seat 12. Figure 4 As shown, a limiting hole 125 is provided on the fixing seat 12 , and the hook body 11 has a locking pin 13 which can be inserted into or withdrawn from the limiting hole 125 to lock or unlock the fixing seat 12 and the hook body 11 .

[0042] Here, it should be noted that the hook 1 is not limited to the sun visor hook, but can also be a hook used in daily life, a hook inside a car, etc. It can also be used in production workshops, kitchens, architectural decoration and other fields. The present disclosure does not limit this. Specifically, the sun visor hook will be taken as an example below to introduce its structure in detail. In the present disclosure, when the connecting portion 112 is inserted into the inner cavity of the fixing seat 12, the matching mode of the two can be set. For example, the connecting portion 112 is inserted upward into the fixing seat 12 and is upper-positioned through the top wall of the fixing seat 12, and the locking pin 13 is inserted radially into the limiting hole 125 of the fixing seat 12 to achieve the lower limit, thereby achieving the connection between the fixing seat 12 and the hook body 11. Of course, in other embodiments, by designing the outer diameter of the connecting portion 112 and the inner diameter of the fixing seat 12, for example, by making the two have a clearance fit or an interference fit, and at the same time cooperating with the locking pin 13, the connection between the two can also be achieved.

[0043] In the hook provided by the present disclosure, the fixing seat 12 and the hook body 11 are split structures. The fixing seat 12 can be installed at a predetermined position first, and then the connecting portion 112 is inserted into the inner cavity of the fixing seat 12, and the locking pin 13 is inserted into the limiting hole 125 of the fixing seat 12 to achieve the connection between the fixing seat 12 and the hook body 11. The hook body 11 can be stably and firmly fixed at the position where the fixing seat 12 is located. No special tools are required during installation, and the operation is simple and convenient, which improves the assembly efficiency. When the hook 1 needs to be disassembled, the locking pin 13 is pulled out from the limiting hole 125, and the connecting portion 112 is withdrawn from the fixing seat 12, so that the hook body 11 can be disengaged from the fixing seat 12, and then the fixing seat 12 is removed to complete the removal of the hook 1.

[0044] In order to ensure the stability of the connection when the connecting portion 112 is inserted into the fixing seat 12, in an exemplary embodiment of the present disclosure, Figure 3 , Figures 8 to 10As shown, a first buckle 123 is provided on the first side wall opposite to the fixing seat 12, and a first clamping hole 113 is opened on the first side wall corresponding to the connecting portion 112. The first buckle 123 and the first clamping hole 113 cooperate to connect the hook body 11 and the fixing seat 12. In this embodiment, as Fig. 9 As shown, the first side wall is provided with an opening 126 extending to the top wall, one end of the first buckle 123 is connected to the first side wall, and the other end extends into the inner cavity of the fixing seat 12. The fixing seat 12 can be made of elastic material. When the hook body 11 is installed upward, when the upper part of the connecting portion 112 moves to the position of the first buckle 123, the first buckle 123 deforms outward and continues to move upward. At the first clamping hole 113, the first buckle 123 automatically recovers the deformation and is clamped into the first clamping hole 113, thereby realizing the clamping connection between the fixing seat 12 and the connecting portion 112. In other embodiments, the first buckle 123 and the first clamping hole 113 can also be other clamping structures, and their structures can be set as needed.

[0045] For the hook portion 111, the orientation of the bayonet 1110 is required, which will affect the flipping direction of the sun visor 2. In order to ensure that the hook body 11 is installed in place in one step, an anti-mistake structure 124 is provided on the hook body 11. Fig. 9 As shown, the limiting hole 125 (the side with the locking pin 13) on the fixing seat 12 and one of the first buckles 123 are located on the same side, and the first buckle 123 on this side is provided with an anti-error structure 124. The anti-error structure 124 can be a rectangular convex block arranged on the outer surface of the first buckle 123, which will not affect the clamping effect of the first buckle 123, and is arranged on the same side as the locking pin 13. The corresponding position of the mounting hole of the body sheet metal 3 is provided with an avoidance groove matched with the anti-error structure 124. The anti-error structure 124 can only be pushed into the mounting hole when it is installed in a predetermined direction. When inserted in other directions, it will be stopped, which can play an anti-error role. The side where the locking pin 13 and the anti-error structure 124 are located is the side where the opening away from the bayonet 1110 is located, which is convenient for the operator to identify during installation and improve assembly efficiency.

[0046] There are many structures for installing the fixing base 12 at the predetermined position. Figure 6 As shown, a second buckle 121 is provided on the second side wall opposite to the fixing seat 12, and an annular buckle 122 is provided on the outer peripheral wall of the fixing seat 12 below the second buckle 121. The second buckle 121 and the annular buckle 122 cooperate to form a limiting space 120. Fig.13 and Fig.14As shown, taking the installation of the fixing seat 12 to the body sheet metal 3 as an example, the body sheet metal 3 is provided with a mounting hole, the fixing seat 12 is installed from bottom to top, the second buckle 121 crosses the mounting hole and is clamped on the top surface of the body sheet metal 3, the annular clamping protrusion 122 is in contact with the bottom surface of the body sheet metal 3, and the height of the limiting space 120 can be the thickness of the body sheet metal 3, and the fixing seat 12 can be stably fixed on the body sheet metal 3. The annular clamping protrusion 122 can surround the fixing seat 12 for a week, as shown in FIG. Fig.10 As shown, the annular protrusion 122 is a disconnected design, which can reduce the weight of the fixing seat 12 and achieve a lightweight design without affecting the installation and fixation of the fixing seat 12. Similarly, the interior of the connecting portion 112 can be a solid structure or a cavity structure, which can reduce the weight of the hook body 11.

[0047] In the embodiment of the sun visor hook, the fixing seat 12 is first installed on the body sheet metal 3 and pushed upward, and then the ceiling 4 is installed. Fig.16 As shown, the top surface of the main body 110 abuts against the surface of the ceiling 4. In the present disclosure, Figure 5 As shown, the main body 110 is further provided with a support portion 114 arranged around the connecting portion 112, and the height of the support portion 114 is between the connecting portion 112 and the main body 110. The support portion 114 can increase the structural strength of the hook body 11. In this embodiment, Figure 6 As shown, the support portion 114 and the annular protrusion 122 have flush surfaces. Fig.16 As shown, the top surface of the support portion 114 can be pressed against the body sheet metal 3 to increase the contact area with the body sheet metal 3, play a supporting role, and be more firm and reliable.

[0048] There are many ways to insert or withdraw the locking pin 13 from the limiting hole 125 in the radial direction. In the present disclosure, the locking pin 13 has an insertion section for inserting into the limiting hole 125, an operation section located outside, and a connecting section connecting the insertion section and the operation section. The locking pin 13 passes through the main body 110 and the support section 114. The operation section is stopped outside the main body 110, and the insertion section extends out of the support section 114 to extend into the limiting hole 125. The locking pin 13 can be inserted or pulled out in the radial direction to achieve locking or unlocking of the hook 1. The lock hook can be detachably installed at a predetermined position and can be installed or removed as needed, which is more flexible and convenient.

[0049] To prevent the locking pin 13 from coming off the hook body 11 when being pulled out, Figure 5 As shown, a stop protrusion 131 is provided on one side of the connecting section close to the insertion section. The position of the stop protrusion 131 can be designed according to the length inserted into the limiting hole 125.

[0050] In this disclosure, Figure 4As shown, the connection section is provided with a pre-tightening protrusion 132. The pre-tightening protrusion 132 can be arranged at one end of the connection section close to the operating section, and when the locking pin 13 is inserted into place, it plays a role in fixing the locking pin 13, and will not always cause abnormal noise and shaking.

[0051] In this disclosure, Figure 4 As shown, a receiving groove 1101 matching the shape of the operating section is provided on the outer wall of the main body 110, and an operating notch 130 is provided between the operating section and the receiving groove 1101. The operating section is located in the receiving groove 1101, does not protrude from the surface of the main body 110, and does not occupy too much space. The operating notch 130 can be easily inserted into the receiving groove 1101 to operate the lock pin 13, and the lock pin 13 can be pried axially to facilitate outward extraction.

[0052] The hook portion 111 on the hook body 11 can be any appropriate structure. In the present disclosure, a bayonet 1110 for accommodating articles is formed between the two open ends of the hook portion 111, and an inwardly bent elastic portion 115 is provided at the upper open end of the bayonet 1110. The flip shaft 21 of the sun visor 2 can be installed in the bayonet 1110, and the elastic portion 115 and the protrusion 116 can both increase the fixing ability of the flip shaft 21, so that it can be stably installed in the bayonet 1110.

[0053] According to a second aspect of the present disclosure, a sun visor assembly is provided, including a sun visor 2 and the hook 1 introduced above, wherein the flip axis 21 of the sun visor 2 is rotatably mounted in the hook-shaped portion 111 of the hook 1, and the fixing seat 12 is used to mount the sun visor 2 on the vehicle body sheet metal 3.

[0054] When installing the sun visor assembly provided by the present invention, first push the fixing seat 12 upward into the mounting hole on the vehicle body sheet metal 3, and fix it by the second buckle 121 and the annular buckle 122, and then install the ceiling 4, which can be connected to the vehicle body sheet metal 3 by magnets, Velcro, fasteners, buckles, etc.; then install the hook body 11, extend the connecting part 112 into the inner cavity of the fixing seat 12, and realize the snap connection by the cooperation of the first buckle 123 and the first clamping hole 113. After the hook body 11 is installed in place, push the locking pin 13 radially into the limiting hole 125 to firmly lock the hook body 11 to prevent movement and falling. After completing the installation of the hook 1, the flip axis 21 of the sun visor 2 can be installed in the bayonet 1110 of the hook-shaped part 111 to realize the flipability of the sun visor 2.
