Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a sun visor. Background Technology

[0002] Automotive sun visors are typically mounted on the vehicle body and can be rotated open and folded to provide sun protection for the driver and front passenger. They are opened when in use and folded away from the roof when not in use. Typically, one end of the sun visor along its length has a hinge rod. The sun visor is rotatably mounted on the hinge rod to open and close. The hinge rod is hinged to the vehicle body and can rotate vertically, allowing for front and side sun shading adjustment. Existing sun visors are usually single-piece structures, with the shading angle adjusted by flipping. However, the shading area is not adjustable for the same viewing angle, and the adjustable viewing angle range is limited, resulting in low utilization. Installing a sub-plate on the sun visor body can increase the adjustable shading area. In use, the sun visor body and sub-plate are rotated sequentially for adjustment. However, once the sun visor body is open, the sub-plate only has fully open and fully closed states; that is, the shading angle is still only adjusted by the flip angle of the sun visor body, limiting the adjustment range. Utility Model Content

[0003] The purpose of this utility model is to provide a sunshade that solves the problem of the fixed and non-adjustable viewing angle of the sub-plate on the sunshade.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A sun visor includes a main board assembly and a sub-board assembly rotatably mounted on the main board assembly; the sun visor also includes a rotating assembly, which includes a first rotating shaft and an elastic component. The elastic component is fixed to the main board assembly. A first end of the first rotating shaft is rotatably mounted on the main board assembly and its outer peripheral wall abuts against the elastic component. A second end of the first rotating shaft is connected to the sub-board assembly. When the sub-board assembly rotates, it drives the first rotating shaft to rotate. The first end of the first rotating shaft can be suspended at any angle under the elastic action of the elastic component.

[0006] In some embodiments, the rotating assembly further includes a fixing seat disposed on the main board assembly. The fixing seat has a receiving cavity and a first limiting groove. The first limiting groove is located at the opening end of the receiving cavity. At least a portion of the elastic component is located in the receiving cavity. When the first end of the first rotating shaft is rotated into the first limiting groove, the elastic component can be limited to the receiving cavity.

[0007] In some embodiments, the resilient component includes:

[0008] The card holder has a through hole, and two first limiting grooves are respectively disposed at both ends of the through hole. When the first rotating shaft passes through the through hole and the first limiting groove at the same time, the card holder is limited to the receiving cavity.

[0009] A spring component, one end of which is fixed to the card holder, and the other end of which abuts against the first rotating shaft.

[0010] In some embodiments, one end of the spring member is provided with a retaining plate, which is fixedly connected to the retaining seat, and the other end of the spring member is provided with a baffle, which is slidably installed on the retaining seat and abuts against the first rotating shaft.

[0011] In some embodiments, the card holder is a U-shaped plate, the spring is disposed in the U-shaped groove of the U-shaped plate, the two ends of the card plate are respectively engaged with the two side plates of the card holder, and the through hole is formed between the bottom of the U-shaped groove and the baffle.

[0012] In some embodiments, the two side plates of the card holder are respectively provided with sliding grooves, and the two ends of the baffle are respectively slidably installed in the sliding grooves.

[0013] In some embodiments, the back side of the motherboard assembly is provided with a mounting slot, and a rotating assembly is provided at each of the two opposite slot walls of the mounting slot to rotatably mount the sub-board assembly; or, on the two opposite slot walls of the mounting slot, one is provided with the rotating assembly and the other is provided with a second rotating shaft to rotatably mount the sub-board assembly.

[0014] In some embodiments, the motherboard assembly is provided with a second limiting groove, and the outer peripheral wall of the second rotating shaft is provided with a positioning shoulder. When the second rotating shaft is rotatably disposed in the second limiting groove, the positioning shoulder abuts against the two end faces of the second limiting groove to limit axial movement.

[0015] In some embodiments, the sun visor further includes a makeup mirror disposed at the bottom of the mounting slot of the main board assembly or on the sub-board assembly, wherein the sub-board assembly can cover the makeup mirror when rotated and stacked in the mounting slot.

[0016] In some embodiments, the outer peripheral wall of the first end of the first rotating shaft is provided with a groove, which extends along the axial direction of the first rotating shaft.

[0017] The beneficial effects of this utility model are:

[0018] The sun visor provided by this utility model, by setting a rotating component, allows the sub-panel assembly to be rotatably installed on the main body assembly. Under the action of the elastic component of the rotating component, when the sub-panel assembly drives the first rotating shaft to rotate, the sub-panel assembly can be suspended at any angle because the first rotating shaft is always subjected to the elastic force of the elastic component. This results in multiple adjustable viewing angles, which, when combined with the adjustable viewing angles of the main body assembly, greatly increase the overall adjustable range of the sun visor's viewing angle, making it more convenient and flexible to use.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figures 1-4 As shown, this embodiment of the utility model provides a sun visor, which includes a main board assembly 1 and a secondary board assembly 2 rotatably mounted on the main board assembly 1. When the sun visor is not in use, the secondary board assembly 2 overlaps with the main board assembly 1, and the main board assembly 1 is stored in the roof wall of the vehicle. Figure 1 As shown; when a sunshade is needed, such as Figure 2 As shown, motherboard assembly 1 can be rotated downwards to open; further opening of sub-board assembly 2 is required, as shown below. Figure 3 Sub-board assembly 2 rotates downwards to open; wherein, main board assembly 1 and sub-board assembly 2 are connected by rotating assembly 3, as shown below. Figure 3 As shown, at least one end of the sub-plate assembly 2 is provided with the rotating assembly 3 to achieve rotatable installation with adjustable angle.

[0039] like Figures 4-6 The rotating component 3 includes a first rotating shaft 31 and an elastic component 32. The elastic component 32 is fixed on the main board component 1. The first end of the first rotating shaft 31 is rotatably mounted on the main board component 1 and the outer peripheral wall of the first rotating shaft 31 abuts against the elastic component 32. The second end of the first rotating shaft 31 is connected to the sub-board component 2. When the sub-board component 2 rotates, it drives the first rotating shaft 31 to rotate. The first end of the first rotating shaft 31 can be suspended at any angle under the elastic action of the elastic component 32.

[0040] The sunshade provided by this utility model, by setting a rotating component 3, allows the secondary plate component 2 to be rotatably mounted on the main plate component 1. Under the action of the elastic component 32 of the rotating component 3, when the secondary plate component 2 drives the first rotating shaft 31 to rotate, the first rotating shaft 31 is always subjected to the elastic force of the elastic component 32 during rotation, so that an elastic damping connection is formed between the secondary plate component 2 and the main plate component 1. The secondary plate component 2 can be suspended at any rotation angle, thus having multiple adjustable viewing angles. The superposition of the adjustable viewing angles of the main plate component 1 greatly increases the overall adjustable range of the sunshade's viewing angle, making it more convenient and flexible to use. The main plate component 1 includes components such as a main plate, a light source, and connectors, while the secondary plate component 2 includes components such as a secondary plate and a protective film. Sunshade structures not described in detail in this specification all adopt existing technology and will not be elaborated upon here; only the improvements are described in detail. The second end of the first rotating shaft 31 has a non-circular cross-section (e.g., Figure 5 As shown, the outer peripheral wall of the second end of the first rotating shaft 31 is provided with a protruding ridge. When it is assembled with the end shaft hole of the sub-plate assembly 2 (the cross-sectional shape of the shaft hole matches the cross-section of the second end of the first rotating shaft 31), the first rotating shaft 31 and the sub-plate assembly 2 can rotate synchronously.

[0041] In some embodiments, the rotating assembly 3 further includes a fixing seat 33, which is disposed on the main board assembly 1. The fixing seat 33 is provided with a receiving cavity 331 and a first limiting groove 332. The first limiting groove 332 is located at the opening end of the receiving cavity 331, and at least part of the elastic component 32 is located in the receiving cavity 331. When the first end of the first rotating shaft 31 is rotated and disposed in the first limiting groove 332, the elastic component 32 can be limited to the receiving cavity 331.

[0042] Combination Figures 4-6 The mounting base 33 has lifting lugs on both sides, and positioning holes 333 on the lifting lugs. Correspondingly, the main board assembly 1 has two positioning posts 13. When the mounting base 33 is installed, the two positioning holes 333 are respectively inserted into the two positioning posts 13, and the mounting base 33 is fixedly installed by pressing with the main board cover plate. In other embodiments, the mounting base 33 can also be fixed to the main board assembly 1 by bolts. The cavity 331 on the fixed base 33 has a single-sided opening structure, and the first limiting groove 332 is an open arc-shaped groove, which facilitates the installation of the first rotating shaft 31. The first limiting groove 332 is located in front of the opening of the cavity 331. The first end of the elastic component 32 can be inserted into the cavity 331, and the other end is located at the first limiting groove 332. When the first rotating shaft 31 is rotated and installed in the first limiting groove 332, the elastic component 32 can be limited to the cavity 331, so as to achieve fixed installation and always elastically abut against the first rotating shaft 31. Under the elastic force of the elastic component 32, the first rotating shaft 31 can be suspended at any rotation angle.

[0043] In some embodiments, the elastic component 32 includes a retainer 321 and a spring member 322. The retainer 321 has a through hole, and two first limiting grooves 332 are respectively disposed at both ends of the through hole. When the first rotating shaft 31 passes through both the through hole and the first limiting grooves 332, the retainer 321 is limited to the receiving cavity 331. One end of the spring member 322 is fixed to the retainer 321, and the other end of the spring member 322 abuts against the first rotating shaft 31.

[0044] like Figure 5 and Figure 6 As shown, the first limiting groove 332 is provided on the extension sections of the two side walls of the receiving cavity 331. When the holder 321 is inserted into the receiving cavity 331, the two first limiting grooves 332 are located at both ends of the through hole and are coaxial, so that the first rotating shaft 31 can be simultaneously inserted into the through hole and the first limiting groove 332. During installation, the first rotating shaft 31 can be inserted into the through hole first, and then placed into the two first limiting grooves 332 from top to bottom to achieve limiting and rotational installation along the axial direction of the first rotating shaft 31. The spring member 322 can be a compression spring, with one end of the spring connected to the through hole, and the two ends of the spring abutting against the first rotating shaft 31 and the holder 321 respectively, to achieve elastic limiting of the first rotating shaft 31.

[0045] In some embodiments, one end of the spring member 322 is provided with a retaining plate 323, which is fixedly connected to the retaining seat 321, and the other end of the spring member 322 is provided with a baffle 324, which is slidably installed on the retaining seat 321 and abuts against the first rotating shaft 31.

[0046] like Figure 7 The mounting plate 323 and baffle 324 facilitate the installation and positioning of the spring component 322. The baffle 324 allows the spring component 322 to abut against the first rotating shaft 31, increasing the contact area between the spring force and the first rotating shaft 31. This ensures that the baffle 324 remains in contact with the first rotating shaft 31 throughout its rotation. The baffle 324 extends along the axial direction of the first rotating shaft 31, ensuring a contact length along the axial direction of the first rotating shaft 31 and guaranteeing its axial consistency and stability.

[0047] In some embodiments, the card holder 321 is a U-shaped plate, the spring member 322 is disposed in the U-shaped groove of the U-shaped plate, the two ends of the card plate 323 are respectively engaged with the two side plates of the card holder 321, and a through hole is formed between the bottom of the U-shaped groove and the baffle 324.

[0048] For example Figure 7 The card holder 321 is a U-shaped plate. A U-shaped groove is formed between the two side plates and the arc-shaped bottom plate of the U-shaped plate. The opening of the U-shaped groove faces the fixed seat 33. The first rotating shaft 31 passes through the U-shaped groove. The two side plates of the U-shaped plate are respectively provided with mounting holes 3211 at the opening end. The two ends of the card plate 323 are provided with tongues, which are inserted into the mounting holes 3211 to install the card plate 323. One end of the spring member 322 is fixed to the card plate 323, and the baffle 324 at the other end forms a through hole with the arc-shaped bottom plate of the card holder 321. The first rotating shaft 31 passes through the through hole. Correspondingly, the outer peripheral wall of the first end of the first rotating shaft 31 is provided with a groove 311, which extends along the axial direction of the first rotating shaft 31. When the groove 311 on the outer peripheral wall of the first rotating shaft 31 rotates to abut against the baffle 324, the corresponding sub-plate assembly 2 is fully rotated into an open or closed state. Preferably, two grooves 311 are provided on the first rotating shaft 31. The two grooves 311 are symmetrically arranged on the outer peripheral wall of the first rotating shaft 31. When the sub-plate assembly 2 rotates 0° and 180° relative to the main plate assembly 1, the baffle 324 abuts against the two grooves 311 respectively. When the first rotating shaft 31 rotates to the point where the baffle 324 abuts against the groove 311, a sudden change in the spring force and a clicking sound will occur, indicating that the first rotating shaft 31 or the sub-plate assembly 2 has rotated to the correct position, prompting the operator to stop rotating or rotate in the opposite direction. Therefore, along the axial direction of the first rotating shaft 31, the length of the baffle 324 does not exceed the length of the groove 311.

[0049] In some embodiments, the card holder 321 has a sliding groove 3212 on each of its two side plates, and the two ends of the baffle 324 are slidably installed in the sliding groove 3212.

[0050] like Figure 7 The two side plates have grooves 3212 at opposite positions. The baffle 324 has protrusions at both ends, which slide within the grooves 3212. Simultaneously, the portions of the baffle 324, excluding the protrusions, are sandwiched between the two side plates. When the first rotating shaft 31 rotates, it abuts against the baffle 324, thereby causing the elastic element to deform elastically and generate elastic force. The grooves 3212 help ensure the compression direction of the elastic element and the sliding direction of the baffle 324.

[0051] In some embodiments, the back side of the motherboard assembly 1 is provided with a mounting groove 11, and a rotating assembly 3 is provided at each of the two opposite groove walls of the mounting groove 11 to rotate and mount the sub-board assembly 2; or, on the two opposite groove walls of the mounting groove 11, one is provided with a rotating assembly 3 and the other is provided with a second rotating shaft 4 to rotate and mount the sub-board assembly 2.

[0052] like Figure 3 When the sub-board assembly 2 rotates to be housed on the back side of the main board assembly 1, it is housed within the mounting groove 11, facilitating the flatness of the back side of the main board assembly 1. By placing the rotating assembly 3 and / or the second rotating shaft 4 at two opposite groove walls of the mounting groove 11, there is no gap between the sub-board assembly 2 and the main board assembly 1 when the sub-board assembly 2 is rotated open, eliminating the need for additional structural sealing gaps, resulting in a compact structure and a flat appearance. By connecting the sub-board assembly 2 with rotating assemblies 3 at opposite groove walls on both sides, the sub-board is mounted by rotating at two spaced points, providing good stability, balanced damping, and smooth rotation. Of course, in some embodiments, one end of the sub-board assembly 2 can be connected to the main board assembly 1 via the rotating assembly 3, and the other end can be connected to the main board assembly 1 via the second rotating shaft 4, such as... Figure 3 In the embodiment shown, the two ends of the sub-board assembly 2 are respectively provided with a rotating assembly 3 and a second rotating shaft 4 for rotatably mounting on the main board assembly 1. The structure of the second rotating shaft 4 is simpler, the installation volume is smaller, and the cost is saved.

[0053] In some embodiments, the motherboard assembly 1 is provided with a second limiting groove 12, and the outer peripheral wall of the second rotating shaft 4 is provided with a positioning shoulder 41. When the second rotating shaft 4 is rotatably disposed in the second limiting groove 12, the positioning shoulder 41 abuts against the two end faces of the second limiting groove 12 to limit axial movement.

[0054] like Figure 8 and Figure 9As shown, two second limiting grooves 12 are spaced apart on the main board assembly 1. The two second limiting grooves 12 are coaxially arranged and coaxial with the first limiting groove 332. Both second limiting grooves 12 are open arc-shaped grooves, with the same structure as the first limiting groove 332. The second limiting grooves 12 are formed on the two upright plates. Multiple positioning shoulders 41 are spaced apart along the axial direction on the second rotating shaft 4. When the second rotating shaft 4 is rotated within the two second limiting grooves 12, any two positioning shoulders 41 can abut against the sides of the upright plate, achieving axial limiting of the second rotating shaft 4. It can be understood that setting the second limiting grooves 12 as open arc-shaped grooves facilitates the installation of the second rotating shaft 4. One end of the second rotating shaft 4 is rotatably or fixedly connected to the sub-board assembly 2.

[0055] In some embodiments, the sun visor also includes a makeup mirror 5, which is disposed at the bottom of the mounting groove 11 of the main board assembly 1 or on the sub-board assembly 2. When the sub-board assembly 2 is rotated and stacked in the mounting groove 11, it can cover the makeup mirror 5.

[0056] like Figure 3 As shown, the makeup mirror 5 is located at the bottom of the mounting slot 11, or on the side of the sub-board assembly 2 facing the main board assembly 1. When the sub-board assembly 2 rotates and overlaps with the main board assembly 1, it can cover the makeup mirror 5. Simultaneously, the makeup mirror 5 has its own opening and closing cover and light source. Therefore, when the sub-board assembly 2 is opened, the makeup mirror 5 still needs to have its cover opened to be used. It can be understood that the sub-board assembly 2, when in the overlapping state, covers the makeup mirror 5, further increasing the coverage and protection of the makeup mirror 5, which helps improve driving safety.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
