Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, specifically to a fixing structure for a car sun visor pivot seat. Background Technology

[0002] A car sun visor is a panel installed directly above the driver's seat to block sunlight. A sun visor generally consists of a panel, a pivot, and a pivot seat. The panel is connected to the pivot, and the pivot is connected to the pivot seat. The pivot seat is installed on the roof beam. The sun visor can be flipped up and down via the pivot. It can be flipped down to block sunlight when needed and flipped up when not in use, without obstructing the view.

[0003] The sun visor pivot and the roof beam are usually fixed by screws. This fixing method requires an additional screw-driving process on the assembly line, which increases the overall manufacturing cost of the vehicle. Utility Model Content

[0004] Based on the above description, this utility model provides a fixing structure for a car sun visor pivot seat, which solves the problem in related technologies where fixing the sun visor pivot seat and the roof beam with screws adds an extra screw-driving process, increasing the overall vehicle manufacturing cost.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] This application provides a fixing structure for a car sun visor pivot seat, and the technical solution adopted is as follows:

[0007] A car sun visor pivot seat fixing structure includes:

[0008] A ceiling beam with a positioning surface, wherein the positioning surface is provided with mounting holes that penetrate the ceiling beam;

[0009] A pivot seat includes a main body and a connecting part. The main body has a first reference surface. The connecting part can pass through the mounting hole and move until the first reference surface is in contact with the positioning surface. When the connecting part passes through the mounting hole, it is restricted to move relative to the ceiling beam in a first direction and a second direction parallel to the positioning surface. The first direction and the second direction are perpendicular. The main body has a locking hole that passes through in a direction perpendicular to the first reference surface. When the connecting part passes through the mounting hole and moves until the first reference surface is in contact with the positioning surface, the locking hole communicates with the mounting hole.

[0010] An elastic buckle includes two spring pieces connected to each other at one end. Each spring piece includes a connecting section and a fixing section. The connecting sections of the two spring pieces are connected to each other at one end and are V-shaped in an undeformed state. The fixing section is connected to the other end of the connecting section and is located on the side of the two connecting sections that are close to each other. One end of the fixing section is bent away from the other spring piece to form a first limiting piece and is connected to the connecting section. The other end of the fixing section is bent away from the other spring piece to form a second limiting piece.

[0011] The elastic buckle is used to pass through the locking hole and the mounting hole when the connecting part passes through the mounting hole and moves to the first reference surface and the positioning surface, so that the main body and the ceiling beam are located between the first limiting piece and the second limiting piece of each elastic piece in a third direction perpendicular to the positioning surface, and the main body and the ceiling beam abut against the second limiting piece and the first limiting piece respectively, and under their own elastic force, the two elastic pieces abut against the inner walls of the opposite sides of the locking hole in a direction parallel to the first reference surface respectively.

[0012] Preferably, one end of the connecting segment connected to the fixed segment is provided with barbs, one end of the barbs is connected to the connecting segment, and the other end extends along the length of the connecting segment away from the connecting segment to the side of the first limiting piece away from the other spring piece.

[0013] Preferably, the fixed section is provided with a third limiting piece located between the first limiting piece and the second limiting piece and extending in a direction away from each other of the two elastic pieces. The inner walls of the opposite sides of the locking hole are provided with slots for the third limiting piece to be inserted. The elastic buckle is also used to pass through the locking hole and, under its own elastic force, cause the two elastic pieces to abut against the inner walls of the opposite sides of the locking hole in a direction parallel to the first reference plane. Furthermore, the second limiting piece abuts against the side of the main body away from the first reference plane in a direction perpendicular to the first reference plane. The third limiting piece is inserted into the slot and abuts against the inner wall of the slot in a direction perpendicular to the first reference plane, so as to restrict the buckle from moving relative to the main body in a direction perpendicular to the first reference plane by the second limiting piece and the third limiting piece.

[0014] Preferably, the locking assembly further includes a locking member, which is used to connect to the main body when the elastic buckle connects the main body and the ceiling beam, so as to restrict the two spring pieces of the elastic buckle from moving closer to each other.

[0015] Preferably, the locking element includes a stopper block, which is used to insert into the locking hole between the two spring pieces and abut against the two spring pieces when the elastic buckle connects the main body and the ceiling beam.

[0016] Preferably, the locking member further includes a plug, the plug having a second reference surface, the plug being connected to the second reference surface of the plug, the plug having first engaging protrusions on both sides in a fifth direction parallel to the second reference surface, one of the first engaging protrusions being connected to the plug via an elastic limiting plate, the elastic limiting plate being elastically deformable to make the distance between the two first engaging protrusions in the fifth direction variable, and locking grooves being provided on the inner walls of the opposite sides of the locking hole, the locking member being adapted to move from the side of the main body away from the ceiling beam in a third direction with the second reference surface and the first reference surface parallel to each other to insert the plug into the locking hole, and when it moves to the point where the second reference surface abuts against the main body, the two first engaging protrusions are respectively embedded in the two locking grooves to fix the locking member to the main body.

[0017] Preferably, the plug is connected to two elastic cards spaced apart along the fifth direction. The first locking protrusion and the elastic cards are sequentially spaced apart in a direction perpendicular to the second reference plane and away from the plug. The two elastic cards are provided with second locking protrusions on the sides away from each other. The elastic cards can be elastically deformed so that the distance between the two second locking protrusions in the fifth direction is variable. When the plug is inserted into the locking hole, it can be moved until the two second locking protrusions are respectively embedded in the two locking grooves. When the second locking protrusions are respectively embedded in the two locking grooves, the plug is restricted from moving along the direction perpendicular to the first reference plane until it is separated from the main body.

[0018] Preferably, both the first snap-fit ​​protrusion and the second snap-fit ​​protrusion are wedge-shaped.

[0019] Preferably, the elastic buckle is integrally formed.

[0020] Preferably, the rotating shaft seat is provided with a rotating shaft hole for mounting the rotating shaft, and the rotating shaft hole is through in a direction perpendicular to the first reference plane.

[0021] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects:

[0022] 1. This application configures the pivot seat as including a main body and a connecting part, and provides an elastic buckle. During installation, the connecting part passes through the mounting hole and moves to the first reference surface to fit against the positioning surface. At this time, the connecting part is restricted to move relative to the ceiling beam in a first direction and a second direction parallel to the positioning surface, that is, the pivot seat is restricted to move relative to the ceiling beam in a direction parallel to the positioning surface. Then, the elastic buckle passes through the locking hole and the mounting hole. Specifically, the elastic force of the elastic buckle is first overcome to bring the two spring pieces closer to each other until the distance between the two limiting protrusions is less than the width of the locking hole in the second direction, thereby making the elastic buckle... The spring clips can pass through the locking hole and mounting hole. After the elastic clips are in place, they release and return to their original shape. This causes the two spring clips to be positioned on opposite sides of the locking hole in a direction parallel to the positioning surface. The main body and the roof beam are positioned between the limiting piece and the limiting protrusion of each spring clip in a third direction perpendicular to the positioning surface. The main body and the roof beam abut against the limiting piece and the limiting protrusion, respectively. At this time, the cooperation of the limiting piece and the limiting protrusion on each spring clip restricts the movement of the main body relative to the roof beam in a third direction, thereby fixing the pivot seat to the roof beam and achieving the snap-fit ​​fixation of the pivot seat on the roof beam. Compared with the bolt fixing method, the method of fixing the pivot seat and the roof beam by inserting elastic clips is simple and convenient to operate. The fixing of the pivot seat to the roof beam can be completed in one process, reducing the overall vehicle manufacturing cost.

[0023] 2. This application provides barbs on the spring pieces of the elastic buckle. The barbs are connected to the connecting part and extend to the side of the first limiting piece away from the other spring piece. After the elastic buckle is installed, when the pivot seat is subjected to a force away from the ceiling beam, the two spring pieces of the elastic buckle move closer to each other due to the force, and the elastic buckle as a whole moves relative to the ceiling beam along a third direction. Due to the V-shaped structure of the two connecting sections, when the two spring pieces move closer to each other and the elastic buckle as a whole moves relative to the ceiling beam along a third direction, the barbs will abut against the ceiling beam before the first limiting piece is completely detached from the ceiling beam. The two barbs are V-shaped and abut against the two sides of the mounting hole of the ceiling beam respectively. The elastic buckle is blocked by the two barbs and cannot continue to move relative to the ceiling beam. Even if the elastic buckle is subjected to a large force and the two barbs are deformed, the two barbs always remain in abutting state against the ceiling beam, thus limiting the elastic buckle from detaching from the ceiling beam, thereby improving the installation stability of the pivot seat and preventing it from falling off in extreme cases.

[0041] Reference Figure 1-2As shown, this application embodiment provides a car sun visor pivot seat fixing structure, including a roof beam 1, a pivot seat 2, and an elastic buckle 3. The roof beam 1 has a positioning surface 11, and the positioning surface 11 is provided with a mounting hole 12 that penetrates the roof beam 1. The pivot seat 2 includes a main body 21 and a connecting part 22. The main body 21 is provided with a first reference surface 211. The connecting part 22 can pass through the mounting hole 12 and move to the first reference surface 211 to fit with the positioning surface 11. When the connecting part 22 passes through the mounting hole 12, it is restricted to move relative to the roof beam 1 in a first direction and a second direction parallel to the positioning surface 11. The first direction and the second direction are perpendicular. The main body 21 is provided with a locking hole 212 that penetrates in a direction perpendicular to the first reference surface 211. When the connecting part 22 passes through the mounting hole 12 and moves to the first reference surface 211 to fit with the positioning surface 11, the locking hole 212 communicates with the mounting hole 12.

[0042] Reference Figure 3-4 As shown, the elastic buckle 3 includes two spring pieces 31 connected to each other at one end. Each spring piece 31 includes a connecting section 311 and a fixing section 312. The connecting sections 311 of the two spring pieces 31 are connected to each other at one end and are V-shaped in the undeformed state. The fixing section 312 is connected to the other end of the connecting section 311 and is located on the side where the two connecting sections 311 are close to each other. One end of the fixing section 312 is bent away from the other spring piece 31 to form a first limiting piece 3121 and is connected to the connecting section 311. The other end of the fixing section 312 is bent away from the other spring piece 31 to form a second limiting piece 3122. A locking hole 212 is provided on the main body 21 for the elastic buckle 3 to pass through. The locking hole 212 is through in a direction perpendicular to the first reference surface 211. When the connecting part 22 passes through the mounting hole 12 and moves to the point where the first reference surface 211 is in contact with the positioning surface 11, the locking hole 212 communicates with the mounting hole 12. The elastic buckle 3 is used to pass through the locking hole 212 and the mounting hole 12 when the connecting part 22 passes through the mounting hole 12 and moves to the first reference surface 211 and the positioning surface 11, so that the main body 21 and the ceiling beam 1 are located between the first limiting piece 3121 and the second limiting piece 3122 of each elastic piece 31 in the third direction, and the main body 21 and the ceiling beam 1 abut against the second limiting piece 3122 and the first limiting piece 3121 respectively, and under their own elastic force, the two elastic pieces 31 abut against the inner walls of the opposite sides of the locking hole 212 in the direction parallel to the first reference surface 211.

[0043] Reference Figure 1-2 and Figure 5-6 As shown, the first reference surface 211 is disposed on the side of the main body 21 near the connecting part 22, and the connecting part 22 extends in a direction perpendicular to the first reference surface 211, so that the connecting part 22 can be moved to fit the first reference surface 211 and the positioning surface 11 after passing through the mounting hole 12.

[0044] Reference Figure 1-2 and Figure 5-6 As shown, in order to restrict the movement of the connecting part 22 along the first and second directions after it passes through the mounting hole 12, a first locking block 23 is connected to the first reference surface 211 of the main body 21. The first locking block 23 and the connecting part 22 are spaced apart in a fourth direction parallel to the first reference surface 211. During the process of the connecting part 22 passing through the mounting hole 12 and moving to the point where the first reference surface 211 and the positioning surface 11 are in contact, the first locking block 23 is inserted into the mounting hole 12. In the second direction, the first locking block 23 and the connecting part 22 abut against the inner walls on both sides of the mounting hole 12, respectively, to restrict the movement of the connecting part 22, i.e., the rotating shaft seat 2, along the second direction. Meanwhile, the connecting part 22 is configured such that its width in the sixth direction, which is parallel to the first reference surface 211, is slightly smaller than the width of the mounting hole 12 in the first direction. The sixth direction is perpendicular to the fourth direction. The connecting part 22 has wedge-shaped protrusions 24 extending in a direction perpendicular to the first reference surface 211 on both sides in the sixth direction. The thickness of the wedge-shaped protrusions 24 in the sixth direction gradually decreases in the direction away from the main body 21. The maximum thickness of the wedge-shaped protrusions 24 can fill the gap between the connecting part 22 and the inner wall of the mounting hole 12 in the first direction when the connecting part 22 passes through the mounting hole 12. When the connecting part 22 moves through the mounting hole 12 to fit the first reference surface 211 and the positioning surface 11, the wedge-shaped protrusions 24 on both sides of the connecting part 22 abut against the inner walls of the mounting hole 12 on both sides, thereby restricting the movement of the connecting part 22 relative to the ceiling beam 1 in the first direction.

[0045] Reference Figure 1-2 and Figure 5-6 As shown, an extension 25 is connected to the connecting portion 22. The extension 25 and the connecting portion 22 are spaced apart in a fourth direction parallel to the first reference plane 211. The extension 25 is connected to the end of the connecting portion 22 away from the main body 21 and extends towards the main body 21 in a direction perpendicular to the first reference plane 211. The extension 25 can pass through the mounting hole 12 along with the connecting portion 22. As shown, during installation, the extension 25 is first passed through the mounting hole 12. Then, the rotating shaft seat 2 is rotated so that the connecting portion 22 passes through the mounting hole 12 until the first reference plane 211 is in contact with the positioning surface 11. At this time, the rotating shaft seat 2 is restricted to move relative to the ceiling beam 1 in the first and second directions.

[0046] The entire pivot seat 2 is made of plastic and is integrally molded by injection molding.

[0047] Furthermore, refer to Figure 3 As shown, specifically, in the undeformed state, the portion of the fixing section 312 of the elastic buckle 3 located between the first limiting piece 3121 and the second limiting piece 3122 is parallel to the plane of symmetry of the two connecting portions 22. The angle between the first limiting piece 3121 and the portion of the fixing section 312 located between the first limiting piece 3121 and the second limiting piece 3122 is an obtuse angle, and the angle between the second limiting piece 3122 and this portion is a right angle. (Refer to...) Figure 7 As shown, the side of the mounting hole 12 furthest from the snap-fit ​​hole in the second direction has a smaller width in the first direction. When the first reference surface 211 is in contact with the positioning surface 11, the locking hole 212 and this part of the mounting hole 12 are correspondingly connected, and the elastic buckle 3 passes through the locking hole 212 and this part of the mounting hole 12. During installation, after the pivot seat 2 is installed on the ceiling beam 1 until the first reference surface 211 is in contact with the positioning surface 11, the elastic buckle 3 is moved from the side of the pivot seat 2 body 21 furthest from the ceiling beam 1 along the third direction and inserted into the locking hole 212 and the mounting hole 12. During the insertion process, the two connecting sections 311 abut against the inner walls on both sides of the locking hole 212, and due to the V-shaped structure of the connecting section 311, the two spring pieces 31 are squeezed and brought closer to each other until the farthest distance between the two first limiting pieces 3121 is less than the width of the locking hole 212 in the second direction. This allows the elastic buckle 3 to pass through the locking hole 212 and the mounting hole 12. After insertion, the elastic buckle 3 returns to its original shape, causing the two spring pieces 31 to move away from each other until the furthest distance between the two first limiting pieces 3121 is greater than the width of the locking hole 212 and the mounting hole 12 in the second direction. This positions the main body 21 and the ceiling beam 1 in the third direction between the second limiting piece 3122 and the first limiting piece 3121 of each spring piece 31, and the two spring pieces 31 abut against the inner walls of opposite sides of the locking hole 212 in a direction parallel to the first reference plane 211. At this time, under the limitation of the second limiting piece 3122 and the first limiting piece 3121 of each spring piece 31, the main body 21 and the ceiling beam 1 cannot move relative to each other, and the side of the main body 21 away from the limiting piece in the fourth direction cannot move away from the ceiling beam 1, thereby restricting the pivot seat 2 from detaching from the ceiling beam 1.

[0048] Reference Figure 3-4As shown, further, a barb 313 is provided at one end of the connecting segment 311 connected to the fixing segment 312. One end of the barb 313 is connected to the connecting segment 311, and the other end extends along the length of the connecting segment 311 away from the connecting segment 311 to the side of the first limiting piece 3121 away from the other spring piece 31. Specifically, the maximum distance between the two barbs 313 is less than the maximum distance between the two first limiting pieces 3121, so that when the elastic buckle 3 passes through the locking hole 212 and the mounting hole 12, the two spring pieces 31 need to be close to each other until the maximum distance between the two barbs 313 is less than the width of the locking hole 212 and the width of the mounting hole 12. After the elastic buckle 3 is installed, when the pivot seat 2 is subjected to a force away from the ceiling beam 1, the two spring pieces 31 of the elastic buckle 3 move closer to each other due to the force, and the elastic buckle 3 moves as a whole relative to the ceiling beam 1 along a third direction. Due to the V-shaped structure of the two connecting sections 311, when the two spring pieces 31 move closer to each other and the elastic buckle 3 moves as a whole relative to the ceiling beam 1 along a third direction, the barbs 313 will abut against the ceiling beam 1 before the first limiting piece 3121 is completely detached from the ceiling beam 1. The two barbs 313 are in a figure-eight shape and abut against the two sides of the mounting hole 12 of the ceiling beam 1. The elastic buckle 3 is obstructed by the two barbs 313 and cannot continue to move relative to the ceiling beam 1. Even if the elastic buckle 3 is subjected to a large force and the two barbs 313 are deformed, the two barbs 313 always remain in abutting state against the ceiling beam 1, thus restricting the elastic buckle 3 from detaching from the ceiling beam 1, thereby improving the installation stability of the pivot seat 2 and preventing it from falling off in extreme cases.

[0049] Reference Figure 3-4 As shown, further, a third limiting piece 314 is provided on the fixed section 312, located between the first limiting piece 3121 and the second limiting piece 3122 and extending toward the two spring pieces 31 in a direction away from each other. The inner walls of the opposite sides of the locking hole 212 are provided with slots 213 for the third limiting piece 314 to be inserted. The elastic buckle 3 is also used to pass through the locking hole 212 and, under its own elastic force, make the two spring pieces 31 abut against the inner walls of the opposite sides of the locking hole 212 in a direction parallel to the first reference surface 211. The second limiting piece 3122 abuts against the side of the main body 21 away from the first reference surface 211 in a direction perpendicular to the first reference surface 211. The third limiting piece 314 is inserted into the slot 213 and abuts against the inner wall of the slot 213 in a direction perpendicular to the first reference surface 211, so as to restrict the buckle from moving relative to the main body 21 in a direction perpendicular to the first reference surface 211 by the second limiting piece 3122 and the third limiting piece 314.

[0050] When installing the pivot seat 2, the elastic buckle 3 can be pre-installed on the pivot seat 2. Specifically, the elastic buckle 3 is passed through the locking hole 212 and moved until the third limiting piece 314 and the slot 213 are aligned. Then, the elastic buckle 3 returns to its original shape and is inserted into the slot 213 by the third limiting piece 314. At this time, the second limiting piece 3122 and the main body 21 abut against each other on the side away from the first reference surface 211, and the two spring pieces 31 abut against the inner walls on both sides of the locking hole 212 respectively. With the cooperation of the third limiting piece 314 and the second limiting piece 3122, the elastic buckle 3 is prevented from disengaging from the main body 21. (Refer to...) Figure 9 As shown, after the elastic buckle 3 is installed on the main body 21, the rotating shaft seat 2 is installed on the ceiling beam 1. During the installation process, the elastic buckle 3 moves with the rotating shaft seat 2 and is inserted into the mounting hole 12. After the rotating shaft seat 2 is installed in place, the elastic buckle 3 automatically forms a mating connection with the ceiling beam 1 under its own elastic force, thereby realizing the fixed installation of the rotating shaft seat 2 on the ceiling beam 1.

[0051] In this embodiment, refer to Figure 2 As shown, two structural grooves along the length direction are provided on the spring piece 31. The structural grooves extend from the connecting section 311 to the fixing section 312. The part between the two structural grooves is cut off in the middle. The part near the fixing section 312 is bent in the direction away from the two spring pieces 31 to form a third limiting piece 314. The part near the connecting section 311 extends along the length direction of the connecting end to form a barb 313. In this way, the entire elastic buckle 3 can be integrally formed by bending, stamping and other processes from a single elastic metal sheet.

[0052] Reference Figure 1 and Figure 4 As shown, furthermore, in order to prevent the elastic buckle 3 from loosening, the locking assembly also includes a locking member 4, which is used to connect to the main body 21 when the elastic buckle 3 connects to the main body 21 and the ceiling beam 1, so as to restrict the two spring pieces 31 of the elastic buckle 3 from moving closer to each other.

[0053] Reference Figure 4 and Figure 8As shown, specifically, the locking element 4 includes a plug 41, which is used to be inserted into the locking hole 212 when the elastic buckle 3 connects the main body 21 and the ceiling beam 1, located between the two spring pieces 31 and abutting against the two spring pieces 31. The locking member 4 also includes a plug 42, on which a second reference surface 421 is provided. A plug 41 is connected to the second reference surface 421 of the plug 42. The plug 41 has first locking protrusions 43 on both sides in a fifth direction parallel to the second reference surface 421. One of the first locking protrusions 43 is connected to the plug 41 through an elastic limiting plate 44. The elastic limiting plate 44 can be elastically deformed so that the distance between the two first locking protrusions 43 in the fifth direction is variable. Locking grooves 214 are provided on the inner walls of the opposite sides of the locking hole 212. The locking member 4 is adapted to move from the side of the main body 21 away from the ceiling beam 1 in a third direction with the second reference surface 421 and the first reference surface 211 parallel to each other to insert the plug 41 into the locking hole 212. When it moves to the point where the second reference surface 421 abuts against the main body 21, the two first locking protrusions 43 are respectively embedded in the two locking grooves 214 to prevent the locking member 4 from disengaging from the main body 21.

[0054] Reference Figure 6 and Figure 8 As shown, the locking groove 214 is provided on the inner walls of both sides of the locking hole 212 in the second direction, and the first snap-fit ​​protrusion 43 is wedge-shaped. During the process of the first snap-fit ​​protrusion 43 being inserted into the locking hole 212 along with the plug 41, the elastic limiting plate 44 is driven by the inner wall of the locking hole 212 to undergo elastic deformation and thus smoothly insert into the locking hole 212. When the plug 41 is inserted to the second reference surface 421 and abuts against the main body 21, the elastic limiting plate 44 restores its deformation, causing the first snap-fit ​​protrusion 43 to be embedded in the locking groove 214. At this time, the snap-fit ​​cooperation between the first snap-fit ​​protrusion 43 and the locking groove 214, as well as the abutting cooperation between the plug 42 and the main body 21, restricts the movement of the locking member 4 along the third direction relative to the main body 21, that is, restricts the locking member 4 from disengaging from the main body 21. The locking member 4 keeps the elastic buckle 3 connected to the main body 21 and the ceiling beam 1, thereby keeping the rotating shaft seat 2 connected to the ceiling beam 1 and preventing the rotating shaft seat 2 from disengaging from the ceiling beam 1 due to vibration or other factors.

[0055] Reference Figure 1 , Figure 4 and Figure 8As shown, further, two elastic cards 45 are also connected to the plug 41 at intervals along the fifth direction. The first locking protrusion 43 and the elastic cards 45 are distributed at intervals in a direction perpendicular to the second reference plane 421 and away from the plug 42. The two elastic cards 45 are provided with a second locking protrusion 46 on the side away from each other. The elastic cards 45 can be elastically deformed so that the distance between the two second locking protrusions 46 in the fifth direction is variable. When the plug 41 is inserted into the locking hole 212, it can be moved until the two second locking protrusions 46 are respectively embedded in the two locking grooves 214. When the second locking protrusions 46 are respectively embedded in the two locking grooves 214, the plug 41 is restricted from moving in a direction perpendicular to the first reference plane 211 until it is separated from the main body 21.

[0056] Reference Figure 8 As shown, specifically, the second snap-fit ​​protrusion 46 is also wedge-shaped to be inserted into the locking hole 212. Before the pivot seat 2 is installed onto the ceiling beam 1, after the elastic buckle 3 is pre-installed onto the main body 21, the locking member 4 can also be pre-installed onto the main body 21. Specifically, two elastic cards 45 and the second snap-fit ​​protrusion 46 are inserted into the locking hole 212. The two elastic cards 45 are squeezed against the inner wall of the locking hole 212 and deformed to make the distance between the two second snap-fit ​​protrusions 46 less than the width of the locking hole 212, so that the two elastic cards 45 and the second snap-fit ​​protrusion 46 are inserted into the locking hole 212. After the second snap-fit ​​protrusion 46 and the locking groove 214 are aligned, the elastic cards 45 return to their original shape, so that the second snap-fit ​​protrusion 46 is embedded in the locking groove 214, thereby limiting the locking member 4 from disengaging from the main body 21 under the limiting position of the second snap-fit ​​protrusion 46. (Refer to...) Figure 9 As shown, at this point, both the elastic buckle 3 and the locking element 4 are pre-installed on the main body 21. After the pivot seat 2 is installed onto the ceiling beam 1 and the elastic buckle 3 is in place, the locking element 4 is pressed into the locking hole 212 until the first engaging protrusion 43 is embedded in the locking groove 214. The locking element 4 is then in place, completing the installation of the pivot seat 2. The pivot seat 2, elastic buckle 3, and locking element 4 can be pre-assembled together as a single product at the factory. During installation, only one assembly step is required to complete the assembly of the pivot seat 2 onto the ceiling beam 1, further improving efficiency and reducing costs.

[0057] In actual design, the first direction is designed as the vehicle width direction, the second direction as the vehicle length direction, and the third direction as the vehicle height direction. The main body 21 of the pivot seat 2 is located below the roof crossbeam 1, meaning the pivot seat 2 is installed from below the roof crossbeam 1 onto the roof crossbeam 1. In this embodiment, the pivot seat 2 has a pivot hole for mounting the pivot shaft. The pivot hole penetrates in a direction perpendicular to the first reference plane 211, passing through the main body 21 and the connecting part 22. When installing the pivot shaft, the pivot shaft is passed through the pivot hole and installed on the pivot seat 2. Furthermore, referring to… Figure 1 and Figure 6As shown, the extension 25 is configured as a hollow structure, thereby forming a receiving cavity 26 inside the extension 25. The receiving cavity 26 is used for the installation of the sun visor lighting connection interface 5. The connection interface 5 is used for connection to the vehicle body power supply. The connection interface 5 is connected to the control harness. The control harness passes through the hollow pivot and extends through the roof beam 1 and pivot seat 2 to the vehicle body and connects to the sun visor lighting.

[0058] Reference Figure 6 and Figure 10 As shown, to achieve the fixed installation of the connection interface 5 on the rotating shaft seat 2, the receiving cavity 26 is through at both ends in the fourth direction and through on the side away from the main body 21 in the direction perpendicular to the first reference plane 211, so that the two side walls of the receiving cavity 26 in the sixth direction can elastically deform in the sixth direction. Wedge-shaped blocks 27 are respectively provided on the two inner walls of the receiving cavity 26 in the sixth direction, and fixing strips 51 that cooperate with the wedge-shaped blocks 27 are provided on the opposite side walls of the connection interface 5. When the connection interface 5 is installed, it is aligned with the first reference plane 211. The surface 211 is moved vertically into the receiving cavity 26. During the assembly process, the fixing strip 51 and the wedge-shaped locking block 27 cooperate to make the two side walls of the receiving cavity 26 in the sixth direction move away from each other, so that the fixing strip 51 can pass over the wedge-shaped locking block 27. After the fixing strip 51 passes over the wedge-shaped locking block 27, the connecting interface 5 abuts against the bottom wall of the receiving cavity 26 and the two side walls of the receiving cavity 26 in the sixth direction are reset, so that the wedge-shaped locking block 27 cooperates to restrict the movement of the connecting interface 5 away from the main body 21 in the direction perpendicular to the first reference surface 211. Meanwhile, the inner walls of the receiving cavity 26 on both sides in the sixth direction are respectively provided with limiting strips 28. The limiting strips 28 extend in a direction perpendicular to the first reference plane 211. When the connecting interface 5 is embedded in the receiving cavity 26, the two sides of the fixing strip 51 abut against the two limiting strips 28 respectively to restrict the movement of the connecting interface 5 relative to the rotating shaft seat 2 in the sixth direction. The two limiting strips 28 are spaced apart in the fourth direction. When the connecting interface 5 is embedded in the receiving cavity 26, the two fixing strips 51 are located on the side of the two limiting strips 28 that are close to each other in the fourth direction. The two fixing strips 51 abut against the two limiting strips 28 one by one in the fourth direction, so that the movement of the connecting interface 5 relative to the rotating shaft seat 2 in the fourth direction is restricted by the cooperation of the limiting strips 28 and the fixing strips 51, thereby realizing the snap-fit ​​fixation of the connecting interface 5 on the rotating shaft seat 2.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
