Description

Technical Field

[0001] This utility model relates to the field of vehicle accessories, specifically to a sun visor support spring assembly and an interior sun visor. Background Technology

[0002] To improve passenger and driver comfort, car bodies are equipped with sun visors, typically located in the driver's and front passenger's seats. The sun visor is rotatably mounted on a pivot on the vehicle body. Initially, the sun visor is flush against the interior wall; it needs to be rotated to open when in use and then rotated back to its original position after use. This process involves repeated rotation of the sun visor relative to the pivot.

[0003] The inventors discovered in their research that the existing sunshade connection structure has at least the following drawbacks:

[0004] The sun visor and the pivot are rotatably connected by a bushing. After repeated rotation, wear occurs between the bushing and the pivot, causing the sun visor and the pivot to become loose. During use or while the vehicle is in motion, abnormal noise is likely to occur at the connection point between the sun visor and the pivot, affecting the riding experience and shortening the service life.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model.

[0041] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0042] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0043] In existing technology, the sun visor and the pivot are connected by a bushing, and the bushing and the pivot are in rigid contact, relying on circumferential contact for positioning. Since the sun visor needs to rotate relative to the pivot during use, wear occurs after prolonged use, causing the bushing and the pivot to loosen, resulting in abnormal noises during use.

[0044] In view of this, the designers have provided a sun visor support spring assembly that can improve stability, reduce abnormal noise, extend service life, and reduce usage costs.

[0045] Please refer to Figures 1-3 This embodiment provides a sun visor support spring assembly for cooperating with the sun visor pivot 009, including:

[0046] The system comprises a snap-fit ​​plate 100, an arc-shaped elastic snap-fit ​​plate 200, and a fixing plate 300. The snap-fit ​​plate 100 has a positioning groove 101. The arc-shaped elastic snap-fit ​​plate 200 has an arc-shaped convex surface 201 and is installed in the positioning groove 101. The arc-shaped convex surface 201 is arranged opposite to the bottom wall of the positioning groove 101. The fixing plate 300 is fixedly connected to the snap-fit ​​plate 100 and contacts the arc-shaped elastic snap-fit ​​plate 200. At least one end of the arc-shaped elastic snap-fit ​​plate 200 is slidably engaged with the fixing plate 300 in the length direction of the positioning groove 101. The fixing plate 300 is used to limit the translation of the arc-shaped elastic snap-fit ​​plate 200 relative to the snap-fit ​​plate 100 in the direction from the bottom of the positioning groove 101 to the opening of the groove.

[0047] The arc-shaped convex surface 201 cooperates with the positioning groove 101 to clamp the sun visor shaft 009.

[0048] As described above, the sun visor support spring assembly provided in this embodiment is used as follows:

[0049] The sun visor assembly is mounted on the sun visor shaft 009 via a sun visor support spring assembly. During assembly, the sun visor shaft 009 passes through the positioning groove 101 and is clamped by the snap-fit ​​plate 100 and the arc-shaped elastic snap-fit ​​plate 200. The arc-shaped elastic snap-fit ​​plate 200 itself has elasticity, which can press the sun visor shaft 009 against the snap-fit ​​plate 100. During use, applying force to the sun visor assembly can drive the sun visor support spring assembly to rotate relative to the sun visor shaft 009. Since the arc-shaped elastic snap-fit ​​plate 200 and the sun visor shaft 009 are elastically matched, the arc-shaped elastic snap-fit ​​plate 200 can adaptively adjust its elasticity when subjected to force. This not only compensates for manufacturing and assembly errors and improves the stability of the connection, but also reduces the wear of the arc-shaped elastic snap-fit ​​plate 200 and extends its service life. When the sunshade pivot 009, the snap-fit ​​plate 100, or the arc-shaped elastic snap-fit ​​plate 200 wears out, the arc-shaped elastic snap-fit ​​plate 200 can undergo elastic deformation to compensate for the wear gap, improve the stability of rotation, reduce the probability of loosening, and extend the service life.

[0050] The following embodiments illustrate the details of the sun visor support spring assembly of this application by way of example.

[0051] Please refer to Figures 1-3 In this embodiment, optionally, the snap-fit ​​plate 100 includes a first side plate 110, an arc-shaped bottom plate 120, and a second side plate 130 connected in sequence. The first side plate 110 and the second side plate 130 are arranged at intervals relative to each other, and the first side plate 110, the arc-shaped bottom plate 120, and the second side plate 130 cooperate to define a positioning groove 101; the arc-shaped elastic snap-fit ​​plate 200 is clamped between the first side plate 110 and the second side plate 130.

[0052] It should be understood that the snap-fit ​​plate 100 can be designed as a one-piece structure, for example, it can be made of stamped metal sheet, which has high structural strength, is easy to process and manufacture, is not easily deformed during use, and has a long service life. In addition, the arc-shaped base plate 120 is approximately a quarter-circle arc plate, which facilitates close contact with the sunshade pivot 009 and provides stability.

[0053] Furthermore, a first guide portion 140 is provided on both the first side plate 110 and the second side plate 130 of the snap-fit ​​plate 100. The first guide portion 140 can be a protrusion or, in this embodiment, a groove. The groove opening of the first guide portion 140 and the groove opening of the positioning groove 101 are located in the same plane. Both first guide portions 140 are located in the middle of the first side plate 110 and the second side plate 130, facilitating processing.

[0054] Obviously, in some embodiments, the number of first guide portions 140 can be one, or the first guide portion 140 can be a protrusion, etc.

[0055] Meanwhile, both the first side plate 110 and the second side plate 130 are provided with fixing holes. For example, the first side plate 110 is provided with two first fixing holes 111, and the first guide portion 140 on the first side plate 110 is located between the two first fixing holes 111; the second side plate 130 is provided with two second fixing holes 131, and the first guide portion 140 on the second side plate 130 is located between the two second fixing holes 131. In this way, the snap-fit ​​plate 100 is provided with a total of four fixing holes.

[0056] Please refer to Figures 1-3 In this embodiment, optionally, the arc-shaped elastic plate 200 has an arc apex, and the arc-shaped elastic plate 200 is symmetrically arranged on both sides of the arc apex. The arc apex of the arc-shaped elastic plate 200 and the snap-fit ​​plate 100 are relatively fixed relative to each other in the length direction of the positioning groove 101. The arc apex of the arc-shaped elastic plate 200 and the snap-fit ​​plate 100 are slidably engaged in the groove depth direction of the positioning groove 101 to adjust the curvature of the arc-shaped elastic plate 200. At the same time, the arc-shaped elastic plate 200 is provided with a second guide portion 210. The number of second guide portions 210 is equal to the number of first guide portions 140 and they are engaged one-to-one. For example, there are two second guide portions 210, which are located on both sides in the width direction of the arc-shaped elastic plate 200. The two second guide portions 210 are slidably engaged with the two first guide portions 140 respectively. Through the cooperation of the first guide portion 140 and the second guide portion 210, the two ends of the arc-shaped elastic plate 200 can move closer or further apart synchronously, resulting in more uniform deformation of the arc-shaped elastic plate 200 and more uniform elastic force acting on the sunshade pivot 009. Furthermore, the arc-shaped elastic plate 200 elastically deforms in the groove depth direction of the positioning groove 101, and its two ends move synchronously in the length direction of the positioning groove 101. The arc-shaped elastic plate 200 will not move as a whole in the length direction of the positioning groove 101, thereby improving the stability of the position of the arc-shaped elastic plate 200.

[0057] It should be understood that in some embodiments, when the first guide portion 140 is a protrusion, the second guide portion 210 can be a corresponding groove.

[0058] Please refer to Figures 1-3 In this embodiment, optionally, the sunshade support spring assembly further includes a limiting member 400, which is connected to the snap-fit ​​plate 100 or the fixing plate 300 to limit the sliding distance of the end of the arc-shaped elastic snap plate 200 relative to the fixing plate 300. This prevents the arc-shaped elastic snap plate 200 from overstretching, ensuring stable and durable elasticity and reducing the likelihood of failure.

[0059] Furthermore, the limiting member 400 is connected to the fixing plate 300; the arc-shaped elastic plate 200 is provided with an arc-shaped concave surface 202 opposite to the arc-shaped convex surface 201, the limiting member 400 is located between the fixing plate 300 and the arc-shaped concave surface 202, and there is a gap between the limiting member 400 and the arc-shaped concave surface 202; the limiting member 400 is used to contact the arc-shaped concave surface 202 when it is close to the fixing plate 300, so as to limit the deformation range of the arc-shaped elastic plate 200. The limiting is achieved by the limiting member 400 abutting against the bottom surface of the arc-shaped elastic plate 200, and the limiting method is simple and reliable.

[0060] Furthermore, the positions of the limiting member 400 and the fixing plate 300 in the groove depth direction of the positioning groove 101 are adjustable, and the limiting member 400 can be locked after adjustment relative to the fixing plate 300. For example, the limiting member 400 is set as a threaded part, and the limiting member 400 is screwed to the fixing plate 300. By rotating the limiting member 400, the height of the limiting member 400 can be adjusted, thereby adjusting the limiting position and changing the maximum deformation posture of the arc-shaped elastic plate 200, making it flexible to use. Since the limiting member 400 can self-lock through the thread after rotation, the structure is stable.

[0061] Optionally, the fixing plate 300 can be a rectangular plate, with two protrusions 310 on each side. The four protrusions 310 are respectively engaged in four fixing holes, thus providing a firm connection between the fixing plate 300 and the snap-fit ​​plate 100. Furthermore, the fixing plate 300 is firmly positioned relative to the snap-fit ​​plate 100, providing good support for the arc-shaped elastic snap-fit ​​plate 200, allowing the arc-shaped elastic snap-fit ​​plate 200 and the snap-fit ​​plate 100 to firmly hold the sunshade pivot 009, improving stability.

[0062] This embodiment provides a sun visor support spring assembly, which can stably connect the sun visor assembly and the sun visor pivot 009. During use, it is not easy to wear and loosen, the rotation is stable, the operation is not prone to abnormal noise, and the service life is long.

[0063] Please refer to Figures 4-9 This utility model embodiment also provides a vehicle interior sun visor, which includes:

[0064] The sun visor pivot 009, the sun visor assembly, and the sun visor support spring assembly of the above embodiment are included. The sun visor assembly is rotatably connected to the sun visor pivot 009 via the sun visor support spring assembly. The interior sun visor is stable and reliable after installation, not easily worn or loosened over long-term use, does not easily produce abnormal noise, and has a long service life.

[0065] In this embodiment, optionally, the sun visor assembly includes a sun visor body 500 and a conductive slide rail 600. The sun visor body 500 is connected to the conductive slide rail 600, and the conductive slide rail 600 is slidably connected to the sun visor support spring assembly. The conductive slide rail 600 and the sun visor support spring assembly are relatively fixed in the circumferential direction of the sun visor pivot 009. With this design, after the sun visor body 500 rotates and opens relative to the vehicle body, the sun visor body 500 can be pulled to slide relative to the sun visor pivot 009 according to the different directions of sunlight, thereby adjusting the shading position axially along the sun visor pivot 009, providing flexibility in use.

[0066] Furthermore, the vehicle interior sun visor also includes a conductive slider 700, an insulating cover 800, an insulating mounting bracket 900, a circuit board 001, a positive wire 002, a negative wire 003, a positive adapter wire 004, a conductive spring 005, and a negative adapter wire 006; the sun visor pivot 009, the snap-fit ​​plate 100, the arc-shaped elastic snap-fit ​​plate 200, and the fixing plate 300 are all configured as conductive components; the conductive slider 700 and the sun visor pivot 009 are slidably connected in the extension direction of a preset axis, and the two are rotatably connected around the preset axis; the insulating cover 800 is fixed to the conductive slider 700; the insulating mounting bracket 900 is fixed to the snap-fit ​​plate 100; the conductive slide rail 600 is fixedly connected to both the insulating cover 800 and the insulating mounting bracket 900, and there is a gap between the conductive slide rail 600 and the sun visor pivot 009, so that the conductive slide rail 600 and the sun visor pivot 009 will not make electrical contact. A conductive spring 005 is clamped between an insulating mounting bracket 900 and a conductive slide rail 600, with the conductive spring 005 in electrical contact with the conductive slide rail 600. A circuit board 001 is fixed within the sunshade body 500. One end of the positive wire 002 is connected to a power source, and the other end is electrically connected to the conductive spring 005. One end of the positive adapter wire 004 can be electrically connected to the conductive slide rail 600 via a conductive piece 007, and the other end is electrically connected to the circuit board 001. The positive adapter wire 004 can be soldered to the conductive piece 007, and the conductive piece 007 can then be soldered to the conductive slide rail 600. One end of the negative wire 003 is connected to a power source, and the other end is electrically connected to a fixing plate 300. One end of the negative adapter wire 006 is electrically connected to the conductive slider 700, and the other end is electrically connected to the circuit board 001. The preset axis is collinear with the axis of the sunshade rotating shaft 009. After assembly, the positive wire 002, conductive spring 005, positive adapter wire 004, and circuit board 001 are connected sequentially; the negative wire 003, fixing plate 300, arc-shaped elastic clamping plate 200, sun visor pivot 009, negative adapter wire 006, and circuit board 001 are connected sequentially. When the positive wire 002 and negative wire 003 are energized with the positive and negative terminals of the power supply respectively, power can be transmitted to the circuit board 001, thereby controlling the on / off state of the lamp on the circuit board 001. It should be understood that the on / off state of the lamp can be controlled by setting a Hall effect sensor switch. For example, when the makeup mirror on the sun visor assembly needs to be used, opening the mirror cover activates the Hall effect sensor switch, and the lamp lights up; conversely, closing the mirror cover deactivates the Hall effect sensor switch, and the lamp turns off.

[0067] With this design, when the sun visor body 500 needs to be moved along the axial direction of the sun visor pivot 009, both the positive wire 002 and the negative wire 003 are fixed relative to the sun visor pivot 009, and their positions will not change. The lengths of the positive wire 002 and the negative wire 003 will not change continuously as the position of the sun visor body 500 changes. There is no need to set up wire harness redundancy, which reduces costs and reduces the risk of knotting. Meanwhile, the positive adapter wire 004, negative adapter wire 006, conductive slide rail 600 and sun visor body 500 can be regarded as an integral structure. When the sun visor body 500 slides relative to the sun visor pivot 009, the positive adapter wire 004, negative adapter wire 006 and conductive slide rail 600 slide together. There is no relative movement between the positive adapter wire 004 and the negative adapter wire 006. The positive adapter wire 004 and the negative adapter wire 006 do not need to be redundant, shortening the wiring harness, reducing costs, reducing the risk of knotting, and facilitating the miniaturization of the structure.

[0068] It should be understood that the diameter of the sun visor pivot 009 can be set to 8mm or 10mm, etc. This sun visor can be adapted to different vehicle models and has a wide range of applications.

[0069] Furthermore, the positive wire 002, negative wire 003, positive adapter wire 004, or negative adapter wire 006 can all be configured as wire harnesses wrapped with an insulating layer, isolated from each other, making short circuits less likely. The positive wire 002 and negative wire 003 can be run through the sun visor pivot 009, and one end of each can be integrated into an electrical plug 008, which can be plugged into an electrical socket on the vehicle body to achieve power transmission.

[0070] The car sun visor provided in this embodiment has a stable structure, is not easily worn or loosened during use, is not prone to abnormal noise, and has a long service life.

[0071] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
