Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a sun visor. Background Art

[0002] In the prior art, for various functional vehicles, in order to avoid the interference of strong light exposure to the vision of the driver and passengers and potential safety hazards, a sun visor device is usually installed on the ceiling of the vehicle. The existing sun visor is a single-piece structure, and the position can be manually adjusted to block part of the light. However, for large-sized vehicles such as multi-purpose vehicles and sports utility vehicles with large space, due to the large area of ​​the front windshield and side windows, the strong light illumination from the front and sides is also high, and the single-piece sun visor cannot block light from these two areas at the same time.

[0003] Take the common sun visor as an example. As a flat structure, it can only rotate to a specific position relative to the roof of the car body to block the strong light in the corresponding area. This can meet the use needs of ordinary cars. However, for large-sized cars such as SUVs and MPVs with a wider field of vision, when the sun visor is in a position to block the strong light from the front, the strong light from the side windows will have nowhere to be blocked, which seriously affects driving safety and riding comfort; and when the sun visor is adjusted to block the light from the side windows, the strong light from the front will shine into the car, which will also cause visual interference.

[0004] Obviously, if you want to block the strong light from both the front and sides of the vehicle at the same time, the existing single-piece sun visor is obviously incapable of meeting the usage requirements. Summary of the invention

DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] Example 1.

[0031] like Figure 1 and Figure 2As shown, the sun visor described in this embodiment includes a main sun visor 1 and an auxiliary sun visor 2, and a main fixing seat 3 and an auxiliary fixing seat 4 fixed at intervals on the roof of the vehicle body, the main fixing seat 3 is provided with a first rotating shaft 31 and a second rotating shaft 32 fixedly connected to the main fixing seat 3 in sequence and staggered along the direction of travel of the vehicle body, the first rotating shaft 31 has a first section 31a pivoted to the main fixing seat 3 and a second section 31b perpendicular to the first section 31a; one side of the main sun visor 1 is pivoted to the first rotating shaft 31 through the second section 31b, and the other side is provided with a first fixed shaft 11 coaxially arranged with the second section 31b; the auxiliary fixing seat 4 is provided with a hook structure 41 opposite to the direction of travel of the vehicle body, the hook structure 41 is adapted to the first fixed shaft 11, so that the main sun visor 1 can be rotated into the front gear state about the axis of the second section 31b under the action of external force; the first When a fixed shaft 11 disengages from the hook structure 41, the main sun visor 1 can be rotated about the axis of the first section 31a into a side block state under the action of external force; one side of the auxiliary sun visor 2 is pivotally connected to one end of the second rotating shaft 32 away from the main fixed seat 3, and the other end is provided with a second fixed shaft 21 coaxial with the rotation center line of the auxiliary sun visor 2, and the auxiliary fixed seat 4 is provided with an axis hole 42 adapted to the second fixed shaft 21, so that the auxiliary sun visor 2 can be rotated about the axis of the axis hole 42 into a front block state under the action of external force; the main sun visor 1 and the auxiliary sun visor 2 also have a storage state, and when the main sun visor 1 and the auxiliary sun visor 2 are in the storage state, the auxiliary sun visor 2 is located between the vehicle body roof and the main sun visor 1, and is in contact with the vehicle body roof, and the main sun visor 1 is located on the side of the auxiliary sun visor 2 opposite to the vehicle body roof, and is in contact with the outer side of the auxiliary sun visor 2. It should be noted that the first rotating shaft 31 and the second rotating shaft 32 are staggered in sequence along the traveling direction of the vehicle body, which means that the positions of the two are staggered in the traveling direction of the vehicle body, rather than the staggered structures of the two. Figure 1 and Fig.10 As shown, the sun visor provided in this embodiment, the main fixing seat 3 and the auxiliary fixing seat 4 are fixed on the vehicle body ceiling 100, so as to provide a rotation and fixing fulcrum for the main sun visor 1 and the auxiliary sun visor 2. When the main sun visor 1 and the auxiliary sun visor 2 are in the storage state, since the first rotating shaft 31 and the second rotating shaft 32 are sequentially staggered along the moving direction of the vehicle body, the main sun visor 1 and the auxiliary sun visor 2 can be close to and fit with the vehicle body ceiling when not in use, so as to reduce the storage space. The working principle of the sun visor provided in this embodiment is described in detail below:

[0032] When only the front strong light needs to be blocked, such as Figure 3As shown, since one side of the main sun visor 1 is hinged to the second section 31b, and the other side is rotatably cooperated with the hook structure 41 through the first fixed shaft 11, the main sun visor 1 can rotate relative to the main fixed seat 3 under the support of the first fixed shaft 11 and the second section 31b, so as to block the strong light from the front. At the same time, since the first rotating shaft 31 and the second rotating shaft 32 are arranged alternately in sequence along the direction of travel of the vehicle body, when the main sun visor 1 is rotated to the front block state, the auxiliary sun visor 2 is restricted by the main sun visor 1 and cannot be rotated downward, thereby ensuring its stability when it is not in use. In this embodiment, the hook structure 41 is injection molded as one with the auxiliary fixing seat 4 using PA66 and POM materials, so that it can use its own elastic deformation to fix the first fixed shaft 11, thereby satisfying the switching of the first fixed shaft 11 between a fixed and a disengaged state. In addition, the hook structure 41 and the auxiliary fixing seat 4 can also be die-casted, polished and sprayed with ADC12 aluminum alloy to improve the supporting strength of the double sun visor and the anti-destruction strength of the top-mounted bursting airbag.

[0033] When only strong side light needs to be blocked, on the basis that the main sun visor 1 has been rotated to the front blocking state, the user can drive the main sun visor 1 to rotate to the side of the vehicle body along the axis of the first section 31a to achieve the effect of blocking strong side light.

[0034] When strong light needs to be blocked from both the front and the sides, such as Figure 4 As shown, based on the main sun visor 1 having been rotated to the side blocking state, the main sun visor 1 no longer restricts the rotation of the auxiliary sun visor 2. The auxiliary sun visor 2 can rotate relative to the second rotating shaft 32 through the cooperation of the second fixed shaft 21 and the shaft hole 42. It has a simple structure and can also meet the needs of blocking strong light from the front and sides at the same time.

[0035] In this way, the main and auxiliary sun visors can work simultaneously or separately to achieve flexible shading of the front and sides of the vehicle, meet different usage requirements, and have strong flexibility in use. The main sun visor 1 can prevent the auxiliary sun visor 2 from rotating when working alone, avoid occupying space, and ensure the stability of unused parts. The design of the rotating shafts 31, 32 and the fixed shafts 11, 21 allows the opening direction and angle of the main and auxiliary sun visors to be flexibly controlled, accurately blocking the target area, and can smoothly complete the fixing and release of the blocking position. The overall structural design is reasonable, and the main and auxiliary sun visors will not interfere with each other when working in coordination.

[0036] Example 2.

[0037] The sun visor provided in this embodiment is based on the embodiment 1, in order to improve the user experience, such as Figure 2As shown, the main sun visor 1 is embedded with a makeup mirror assembly 5, and the outer surface of the main sun visor 1 is covered with a first fabric layer 12; the surface of the auxiliary sun visor 2 is covered with a second fabric layer 22. The makeup mirror assembly 5 is embedded on the surface of the main sun visor 1, so that when the passenger needs to make up or tidy up the appearance, he only needs to turn the main sun visor 1 which is used relatively frequently, which is more convenient to operate. The covering of the first fabric layer 12 and the second fabric layer 22 makes the outer surface of the sun visor softer and more comfortable, which can effectively block the entry of sunlight, heat and ultraviolet rays, and create a more comfortable driving environment for the passengers in the car.

[0038] In some embodiments, Figure 7 As shown, in order to simplify the manufacturing process, the first fabric layer 12 is formed by punching and sewing the fabric around the periphery, and the first fabric layer 12 is provided with a reserved hole 12a adapted to the makeup mirror assembly 5, and the main sun visor 1 is placed in the first fabric layer 12 through the reserved hole 12a; the second fabric layer 22 is formed by punching and sewing the fabric around the periphery, and the second fabric layer 22 has an unstitched side 22a, and the auxiliary sun visor 2 is placed in the second fabric layer 22 from the unstitched side 22a. Specifically, as Figure 7 As shown, the fabric is punched into a predetermined shape and size, and then Figure 7 The dotted line part is folded in half and then sewn, which is conducive to producing more consistent products and reducing problems caused by size differences. A reserved hole 12a compatible with the makeup mirror assembly 5 is provided on the first fabric layer 12, which is convenient for distinguishing the left and right sides of the first fabric layer 12. At the same time, during production, it is only necessary to remove the excess part of the reserved hole 12a, and then insert the main sun visor 1 into the first fabric layer 12 from the reserved hole 12a to complete the assembly. The first fabric layer 12 chooses to reserve one side without sewing. During assembly, the complex sun visor 2 is inserted into the first fabric layer 12 from the unsewn side 22a. The assembly is simpler and faster, which is conducive to the subsequent processing steps.

[0039] In some embodiments, Figure 5 As shown, in order to enhance the fixation and stability of the fabric layers, retention grooves 6 are provided on the circumferential sides of the main sun visor 1 and the auxiliary sun visor 2, and the sewing edges of the grooves of the first fabric layer 12 and the second fabric layer 22 are inserted into the corresponding retention grooves 6, and retaining teeth 61 are staggered in the retention grooves 6 on the unsewn side 22a, and the fabric on the unsewn side 22a of the second fabric layer 22 is fixed in the corresponding retention grooves 6 by the retaining teeth 61. The retention groove 6 provides an additional fixing point, and by inserting the sewing edges of the first fabric layer 12 and the second fabric layer 22 into the retention groove 6, on the one hand, the fixation and stability of the fabric layers can be enhanced, which helps to prevent the fabric from loosening or shifting during use, and on the other hand, the appearance of the sun visor can be kept neat and beautiful, making the edge of the sun visor look neater. In addition, as Figure 6As shown, by staggeredly arranging the stop teeth 61 in the retention groove 6 of the unstitched side 22a, the unstitched edge of the second fabric layer 22 can be fixed to prevent the auxiliary sun visor 2 from appearing inconsistent or loose in appearance.

[0040] In some embodiments, Figure 2 As shown, in order to ensure the firmness and stability of the sun visor structure, the main sun visor 1 includes a main upper frame 13, a main lower frame 14 and a main spring fixing seat 15. The main upper frame 13 and the main lower frame 14 are tightly matched through positioning columns, and the main upper frame 13 and the main lower frame 14 are limited by concave and convex ribs on their circumferences. The concave and convex ribs cooperate with the outer edges of the main upper frame 13 and the main lower frame 14 to form the retention groove 6. The main spring fixing seat 15 is fixed between the main upper frame 13 and the main lower frame 14, and the main spring fixing seat 15 is provided with a first rotating shaft 31. The auxiliary sun visor 2 includes an auxiliary upper frame 23, an auxiliary lower frame 24 and an auxiliary spring fixing seat 25, the auxiliary upper frame 23 and the auxiliary lower frame 24 are tightly matched by positioning columns, and the auxiliary upper frame 23 and the auxiliary lower frame 24 are limited by concave and convex ribs on the sides, and the concave and convex ribs cooperate with the outer edges of the auxiliary upper frame 23 and the auxiliary lower frame 24 to form the retaining groove 6, the auxiliary spring fixing seat 25 is fixed between the auxiliary upper frame 23 and the auxiliary lower frame 24, and the auxiliary spring fixing seat 25 is provided with an auxiliary spring clip 26 that matches the first rotating shaft 31. In this embodiment, the main sun visor 1 and the auxiliary sun visor 2 have the same structural composition. The main sun visor 1 is used as an example for explanation below: the use of the positioning column 200 helps to fix the main upper frame 13 and the main lower frame 14, ensuring the correct fit between the two, and the limiting design of the concave and convex ribs 300 strengthens the structure of the outer edge, ensuring the stability of the overall component, and at the same time forms a retention groove 6 for easy assembly. The main spring fixing seat 15 is fixed between the main upper frame 13 and the main lower frame 14 by screws, providing a firm support for the main spring clip 16, so that the main sun visor 1 has a smoother and more stable movement when flipping.

[0041] In some embodiments, Figure 8As shown, for good assembly performance, the auxiliary fixing seat 4 has a mounting surface 43 that fits with the vehicle body ceiling, and a fixing structure for fixing the auxiliary fixing seat 4 to the vehicle body is arranged on the mounting surface 43; the surface of the mounting surface 43 is concave to form a U-shaped groove 44, and a fastening block 7 is clamped in the U-shaped groove 44, and the bottom surface of the fastening block 7 has an arc surface that matches the bottom surface of the U-shaped groove 44, and the top of the arc surface bulges toward one side of the mounting surface 43 and cooperates with the bottom surface of the U-shaped groove 44 to form the shaft hole 42. During the installation process, the second fixed shaft 21 is assembled in the U-shaped groove 44, and then the fastening block 7 is snapped into the U-shaped groove 44, providing a stable position, namely the shaft hole 42, for the second fixed shaft 21 to rotate, ensuring the reliable rotation of the auxiliary sun visor 2, and then the auxiliary fixing seat 4 is fixed to the vehicle body ceiling 100 through the fixing structure, and ensure that the mounting surface 43 is in contact with the vehicle body ceiling 100. In this way, through this structure, the snap-in and curved surface design of the fastening block 7 can make the shaft hole 42 formed more simply and effectively, so as to simplify the assembly process, reduce assembly time, and improve production efficiency.

[0042] In some embodiments, Figure 8 and Fig. 9 As shown, in order to maintain the stability of the sun visor during driving, the fastening block 7 is a hollow structure whose top plane is coplanar with the mounting surface 43, and an elastic arm 71 axially arranged along the shaft hole 42 is provided in the fastening block 7, and a window 72 exposing the elastic arm 71 is provided on the arc surface, and at least a part of the elastic arm 71 is located in the shaft hole 42 through the window 72. In this way, when the auxiliary fixing seat 4 is fixed to the vehicle body ceiling 100, the top plane of the fastening block 7 can fit together with the mounting surface 43 and the vehicle body ceiling 100, avoiding the problem of unreliable fixation or looseness due to incomplete fitting; and when the second fixed shaft 21 is assembled to the shaft hole 42 and abuts against the elastic arm 71, the elastic arm 71 will generate an elastic reaction force. This elastic force can help the auxiliary sun visor 2 maintain the required specific angle and provide sufficient support to prevent the sun visor from loosening or shaking by itself. At the same time, the elastic arm 71 can absorb external shocks and vibrations, reduce the degree of vibration transmission to the sun visor, and increase the stability and comfort of the sun visor during vehicle driving.

[0043] In some embodiments, Fig. 9As shown, in order to accurately position and fix, a clamping block 73 and a guide bar 74 are provided on the outer wall of the fastening block 7, and a clamping groove (not shown) adapted to the clamping block 73 and a guide groove (not shown) adapted to the guide bar 74 are provided on the inner wall of the U-shaped groove 44. The adaptation of the clamping block 73 and the clamping groove and the cooperation of the guide bar 74 and the guide groove ensure that the fastening block 7 enters the U-shaped groove 44 in the correct direction and is fixed, preventing it from being misplaced or offset during the installation process, and the existence of the guide bar 74 not only helps to guide the clamping of the clamping block 73 and the clamping groove, but also prevents the fastening block 7 from horizontally slipping out of the U-shaped groove 44, so as to enhance the stability of the fastening block 7 after assembly and avoid unnecessary loosening or movement.

[0044] In some embodiments, Fig.10 and Fig.11 As shown, in order to ensure the accuracy and reliability of the fixing structure during installation, the fixing structure includes an expansion terminal 8, a guide column 81 and a screw hole 82. The guide column 81 is used to guide the expansion terminal 8 to pass through the vehicle body assembly hole (not shown in the figure). The screw hole 82 is integrally formed on the auxiliary fixing seat 4 along the axial direction of the guide column 81. The expansion terminal 8 is provided with a gap for the screw in the screw hole 82 to pass through. The width of the gap is smaller than the aperture of the screw hole 82. In this embodiment, Fig.10 As shown, the body sheet metal 400 on the inner side of the body ceiling 100 is provided with an assembly hole adapted to the expansion terminal 8 and the guide column 81. During installation, the guide column 81 is inserted into the corresponding assembly hole on the sheet metal 400 and guides the expansion terminal 8 through the corresponding assembly hole. Then, when the screw passes through the screw hole 83 and enters the gap, the parts of the expansion terminal 8 located on both sides of the gap can expand in the assembly hole, thereby ensuring that the base body 1 is firmly fixed on the body.

[0045] In some embodiments, Fig.11As shown, for ease of assembly, the expansion terminal 8 has a stop portion 8a that expands downward from its top, and the expansion terminal 8 also has a limiting portion 8b whose radial width is greater than the stop portion 8a, and the limiting portion 8b is located below the stop portion 8a and is spaced apart from the stop portion 8a. During installation, when the parts of the expansion terminal 8 located on both sides of the gap expand in the assembly hole, the stop portion 8a thereof will expand outward accordingly and abut against the sheet metal part 400 to prevent the expansion terminal 8 from falling out of the assembly hole. In the present embodiment, the radial width of the limiting portion 8b is greater than the aperture of the assembly hole. With this structural design, on the one hand, the limiting portion 8b can be used as an indicator to help the installer determine the appropriate installation depth, that is, the installer can rely on the obstruction of the limiting portion 8b to confirm whether the expansion terminal 8 has reached the required depth to avoid inserting too deep or not deep enough. On the other hand, the limiting portion 8b is located below the stop portion 8a and is spaced apart from the stop portion 8a. When the stop portion 8a expands outward accordingly and abuts against the sheet metal part 400, it will cooperate with the limiting portion 8b to clamp the edge of the assembly hole to maintain the integrity and firmness of its structure.

[0046] The sun visor provided in this embodiment is structurally designed so that the main and auxiliary sun visors that work independently share a rotation point and a fixed point. It is not only compatible with different usage directions of the main and auxiliary sun visors, but also can maintain a stable state when opened and stored, thereby achieving all-round shading of the front and sides of the vehicle. The structure is simple, reducing the processing and manufacturing links, and also reducing the difficulty of controlling gaps and deviations during the installation process, thereby increasing reliability.
