[0026] Car sun visors are important parts of car interiors. They mainly block sunlight from the user's field of vision and are of great significance to driving comfort and safety. However, current sun visors are mostly connected to the car body by screwing, snapping, etc., which are difficult to assemble and there is a risk of reverse installation. Additional error-proofing structures need to be designed or the operator needs to put in more effort to complete the installation, which increases the difficulty of component production and assembly.

[0027] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0028] See also Figure 1-6 The sun visor fixing seat provided by the embodiment of the utility model includes a base 10 and a connecting part 20, wherein the base 10 is used to connect with the vehicle body 30, and the connecting part 20 is used to connect the sun visor, and for the convenience of assembly and convenient setting of the connection structure, the base 10 and the connecting part 20 are set as split structures, and are connected into an integrated structure through assembly connection. On this basis, when the operator assembles the fixing seat, he only needs to dock the base 10 with the corresponding structure on the vehicle body 30 first, and then assemble the connecting part 20 with the base 10, or first connect the connecting part 20 to the sun visor and then assemble it with the base 10.

[0029] In order to improve the convenience of assembly, different from the common clip-on structure, see Figure 2 and Figure 3 The base 10 includes an expansion rod 110, which specifically includes a plurality of expansion claws 1110 uniformly arranged along its circumference, and the plurality of expansion claws 1110 are arranged around and the central area is a hollow structure, and the rigid sheet metal structure on the vehicle body 30 has an opening, and the expansion claws 1110 extend into the corresponding hole position; and the connecting portion 20 is correspondingly provided with a plug-in column 210, and the plug-in column 210 is arranged on the side of the connecting portion 20 facing the base 10, and the expansion claw 1110 is in a normal state, that is, without the action of external force, and has a clearance fit with the opening area on the vehicle body 30, so that the expansion claw 1110 can be easily and smoothly inserted into the hole, and when the base 10 is set, see Figure 2 and Figure 4When the connecting portion 20 is assembled with the base 10, the plug-in column 210 will be correspondingly inserted into the central cavity of the expansion rod 110, and at the same time, the plug-in column 210 abuts to push each expansion claw 1110 away from the central axis of the expansion rod 110, so that the expansion claw 1110 is in an expanded state. When the expansion claw 1110 is expanded, the diameter of the end of the expansion claw 1110 extending into the hole of the vehicle body 30 is larger than the diameter of the hole on the vehicle body 30, so that the expansion claw 1110 can be locked on the vehicle body 30, and in the above installation process The expansion rod 110 on the middle base 10 can be easily inserted into the hole in the vehicle body 30, and the operator presses the expansion rod 110 in the connecting part 20 into the central cavity of the expansion claw 1110 to achieve a stable connection between the fixing seat and the vehicle body 30. The operation is simple, convenient and efficient. At the same time, a clamping claw 220 is fixedly provided on the side of the connecting part 20 facing away from the base 10, so as to lock the connecting shaft 40 on the sun visor by clamping the clamping claw 220, thereby realizing the assembly connection between the fixing seat and the sun visor.

[0030] The sun visor fixing seat provided by the embodiment of the utility model is designed with a base 10 and a connecting part 20 of a split structure, so that it can be partially assembled when assembling the fixing seat, and the connection between the fixing seat and the vehicle body 30 is realized by an expansion structure, specifically, an expansion rod 110 is provided on the base 10, and the expansion rod 110 is evenly provided with a plurality of expansion claws 1110 on its circumference. When there is no external force, the expansion claws 1110 are clearance-matched with the mounting holes on the vehicle body 30, so that the operator can easily insert the expansion claws 1110 into the vehicle body 30, and a plug-in column 210 is provided on the connecting part 20. After the expansion claws 1110 are inserted into the vehicle body 30, the connecting part 20 is assembled with the base 10 to The plug-in column 210 is inserted into the expansion rod 110 and each expansion claw 1110 is stretched open, so that the expansion claw 1110 is opened and clamped on the vehicle body 30 to realize the assembly of the base 10 on the vehicle body 30. The operator can manually complete the assembly of the fixing seat, thereby reducing the difficulty of assembly; at the same time, the design of the expansion rod 110 on the base 10 is preferably evenly arranged, that is, when a single expansion rod 110 is set, it is set at the midline position on the base 10, and when two expansion rods 110 are set, they are symmetrically arranged about the bisecting plane of the base 10, so that when the base 10 is installed on the vehicle body 30, there is no need to distinguish between the front and the back, and correct installation can be achieved by aligning the hole positions, and there is no need to set an error-proofing structure to reduce the production cost of the components of the fixing seat.

[0031] In some specific embodiments of the present invention, see Figure 2 and Figure 5, a single expansion rod 110 is evenly provided with four expansion claws 1110 along the circumferential direction, and the plug-in column 210 is designed as a cross column structure, specifically, the plug-in column 210 includes four abutment portions 2110 around it, and each abutment portion 2110 is provided corresponding to an expansion claw 1110, so that when the base 10 and the connecting portion 20 are assembled and connected, each abutment portion 2110 abuts and opens an expansion claw 1110, and see Figure 5 Preferably, the corresponding abutment portion 2110 is located on the bisecting plane of the expansion claw 1110, so that when the expansion claw 1110 is abutted, the spreading force on the expansion claw 1110 is applied to the bisecting plane of the expansion claw 1110, thereby reducing the risk of slippage between the expansion claw 1110 and the abutment portion 2110 when the force is applied, thereby causing the risk of failure of the connection with the vehicle body 30.

[0032] It should be noted that when other numbers of expansion claws 1110 are set, the same number of abutment portions 2110 as the expansion claws 1110 are set on the plug-in column 210 and are also evenly arranged along the circumference of the plug-in column 210, so that the abutment portions 2110 all contact the bisector surface of the expansion claw 1110 when acting with the expansion claw 1110.

[0033] In order to further reduce the difficulty of assembling the fixing base and improve the smoothness of the plug-in column 210 when being inserted into the expansion rod 110, the embodiment of the utility model performs a surface cutting process on the end of the abutment portion 2110 facing the base 10, so that the end of the abutment portion 2110 is an inclined structure inclined toward the base 10. When assembling the base 10 and the connecting portion 20, the plug-in column 210 slides smoothly into the central cavity of the expansion claw 1110 through the inclined guide structure of the abutment portion 2110, thereby realizing the expansion claw 1110 being expanded.

[0034] Considering that the stable connection between the base 10 and the vehicle body 30 is the basis for the effective installation of the sun visor, and the risk of connection failure is relatively high when the base 10 is connected to the vehicle body 30 through a single expansion rod 110, in some embodiments of the utility model, at least two expansion rods 110 are provided on the base 10 to serve as backup for each other, and when the base 10 is provided with two expansion rods 110, the two expansion rods 110 are symmetrically arranged with respect to the bisecting plane of the base 10, so that the force on the base 10 is evenly distributed, and the area of ​​the connection region of the base 10 borne by a single expansion rod 110 is equal. At the same time, the symmetrical arrangement of the two expansion rods 110 with respect to the bisecting plane of the base 10 can improve the assembly efficiency without the need for the assembler to distinguish the installation direction of the base 10.

[0035] It should be noted that, for a base 10 with a greater number of expansion rods 110 , it is preferred to arrange the positions of the expansion rods 110 in such a way that the area of ​​the connection area of ​​each expansion rod 110 on the base 10 is the same.

[0036] In the sun visor fixing seat provided by the embodiment of the utility model, the base 10 and the connecting part 20 are separately arranged, and after the base 10 is arranged at the connection position with the vehicle body 30, the connecting part 20 is assembled. At this time, a variety of assembly methods can be used to achieve the connection between the base 10 and the connecting part 20. For example, threaded holes can be correspondingly opened on the base 10 and the connecting part 20. After the base 10 and the connecting part 20 are docked and the plug-in column 210 is plugged into the expansion rod 110, the base 10 and the connecting part 20 can be locked by bolts; and in order to optimize the use of assembly tools and further reduce the difficulty of assembling the fixing seat, see Figure 2 and Figure 6 In some embodiments of the utility model, the base 10 is provided with card slots 120 on its opposite sides. It should be noted that the opposite sides of the base 10 are two side surfaces of the base 10 that are not in contact. If the base 10 is a four-sided structure, the opposite sides are the two sides where the two opposite sides of the quadrilateral are located; and the connecting part 20 is correspondingly provided with a card joint 230, which is a protruding rod and a hook-shaped connecting structure is provided at the end. When the operator assembles the fixed seat, the base 10 is first placed in the installation hole opened on the vehicle body 30, and then the connecting part 20 is pushed toward the base 10. When the plug-in column 210 is plugged into the expansion rod 110, the hook-shaped area on the card joint 230 is inserted into the card slot 120 to connect the base 10 and the connecting part 20.

[0037] On the basis of the above structure, it is preferred that the card slots 120 on either side of the base 10 are structures that are set through the base 10, so that the operator does not need to align the card joint 230, but only needs to press the connecting part 20 and the base 10 to make the card joint 230 move into place in a single direction, so that the hook area on the card joint 230 reaches the position of the card slot 120 and is tightly connected with the card slot 120, thereby reducing the difficulty of assembling the connecting part 20. At the same time, it is preferred that the connecting part 20 is provided with at least two card joints 230 at intervals in a single connection to improve the connection stability between the connecting part 20 and the base 10 and serve as backup for each other, thereby avoiding the problem of connection failure caused by damage to the hook area structure on a single card joint 230.

[0038] In the above structure, the arrangement of the card slot 120 and the card joint 230 can make the connection part 20 limited and locked relative to the base 10 in three degrees of freedom directions. If the card slot 120 is designed as a structure that passes through the base 10 as mentioned above, it will cause the connection part 20 to slide in the extension direction of the slot body of the card slot 120, and it is necessary to further set a limiting structure. In order to avoid the complexity and production cost of the connection part 20 caused by the above structure, in some embodiments of the utility model, the connection part 20 is an open cavity structure, and the base 10 is embedded in the connection part 20. The opening area of ​​the connecting part 20 is set, that is, the base 10 can be regarded as a cover of the connecting part 20 of the open cavity structure to seal the opening of the connecting part 20, and when the base 10 is embedded in the opening area of ​​the connecting part 20, it will be abutted and limited on all sides by the inner wall of the connecting part 20, so that the connecting part 20 is limited in two directions of freedom. By pushing the card slot 120 and the card connector 230 in the assembly direction of the connecting part 20, the position of the connecting part 20 in three degrees of freedom can be locked, so that the connecting part 20 and the base 10 are stably connected.

[0039] Furthermore, in the sun visor fixing seat provided in the embodiment of the utility model, a clamping claw 220 is provided on the connecting portion 20 to be assembled and connected with the connecting shaft 40 on the sun visor, and the two clamping portions 2210 on the clamping claw 220 are preferably designed as a wave configuration, so as to fit and clamp the connecting shaft 40 through the circular area between the two wave configurations, so as to maintain the clamping state of the connecting shaft 40, and because the sun visor needs to meet the functional requirements of forward shading and side shading, the clamping claw 220 needs to meet the convenient disengagement of the connecting shaft 40 while clamping the connecting shaft 40, so that the sun visor can be detached from the fixing seat and moved forward. The wavy-shaped clamping portion 2210 can be easily pushed in and clamped from the opening position, and the user can apply a downward force on the sun visor to separate the two clamping portions 2210, so that the connecting shaft 40 can be disengaged from the clamping claw 220. At the same time, the spacing between the clamping portions 2210 under normal conditions needs to be smaller than the diameter of the connecting shaft 40, so that the elastic clamping portion 2210 can clamp the connecting shaft 40. It should be noted that the clamping portion 2210 is in a normal state, that is, there is no external force, and there are no other structural parts between the two clamping portions 2210.

[0040] On the basis of the structure of the above-mentioned embodiment, in order to avoid the abnormal disengagement of the connecting shaft 40 from the clamping jaw 220 due to driving bumps on roads with poor road conditions, in some embodiments of the present invention, a blocking rod is further provided at the bottom opening position of the two clamping parts 2210 on the clamping jaw 220, and the blocking rod is hingedly provided at the end of one clamping part 2210 at the opening position of the clamping jaw 220, and the movable end of the blocking rod can be overlapped and locked to the end of the other clamping part 2210. After the sun visor is assembled, the blocking rod is rotated to a hanging state, that is, the movable end of the blocking rod is overlapped and locked to the end of the other clamping part 2210, and the opening area of ​​the clamping jaw 220 is closed. At this time, the connecting shaft 40 cannot be disengaged from the clamping area of ​​the clamping jaw 220; and when lateral shading is required, the blocking rod is first turned away to open the opening of the clamping jaw 220, and then the connecting shaft 40 of the sun visor is disengaged from the clamping jaw 220, so that the sun visor can be rotated to meet the user's lateral shading needs.

[0041] Some embodiments of the utility model also disclose a vehicle, which is provided with sun visors in front of the main driver and the co-driver, and the sun visors are connected to the vehicle body through the sun visor fixing seat provided by any of the above embodiments to meet the front and side sunshade needs of passengers. Since the above sun visor fixing seat has the above effects, the above vehicle also has corresponding effects, which will not be repeated here. At the same time, it should be noted that the above vehicle can be a pure electric drive vehicle, a hybrid vehicle or a fuel vehicle, etc.

[0042] It should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the utility model can be combined with each other.

[0043] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

For those skilled in the art, the utility model can have various modifications and changes. The scope of the utility model involved in the utility model is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but also should cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the concept of the above-mentioned utility model.
