Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to a sun visor resetter, a sun visor assembly, and an automobile. Background Technology

[0002] Car sun visors are used to block glare from the front or sides of a vehicle by flipping and adjusting their angle while the vehicle is in motion. This prevents direct sunlight from interfering with the driver's and passengers' vision, reducing visual fatigue and safety hazards caused by strong light.

[0003] Currently, car sun visors have an automatic reset function, allowing them to automatically return to their initial position after use for user convenience. However, the automatic reset structures of car sun visors on the market mainly consist of a reinforcing tube and a metal retaining spring. The reinforcing tube is fixed to the car body, and the metal retaining spring is linked to the sun visor body via a snap-fit ​​mechanism. This structure relies on the retaining spring to generate elastic force due to the change in surface difference of the arc surface during rotation to complete the reset. However, the spring tension is relatively low, resulting in poor automatic reset performance and affecting the user experience. Therefore, technological improvement and optimization are urgently needed. Utility Model Content

[0026] In the sun visor resetter of this application embodiment, the elastic element drives the contact element and the cam to abut. When the sun visor is flipped downwards, it drives the sun visor frame body to move synchronously. The contact element moves from the reset working surface to the positioning working surface, increasing the elastic deformation of the elastic element. At this time, the elastic potential energy increases, making the force between the contact element and the positioning working surface larger. This allows the sun visor to be stably suspended at any adjustable angle within the adjustment range, meeting the personalized needs of different drivers and passengers for sun visor angles. When resetting upwards, the contact element moves from the positioning working surface to the reset working surface. Since the reset working surface is concave on the side away from the contact element, a downward slope is formed. At the same time, with the deformation restoring force of the elastic element, the contact element can continue to move on the reset working surface, realizing the automatic reset function of the sun visor.

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0052] Please see Figure 1 , Figure 2 and Figure 3 This application provides a sun visor resetter, which includes a rotating shaft 1, a sun visor frame body 2, a contact 3, a cam 4, and an elastic element 5. The sun visor frame body 2 can rotate around the rotating shaft 1; the contact 3 is movably mounted on the sun visor frame body 2; the cam 4 is mounted on the rotating shaft 1, and the cam 4 is provided with a positioning working surface 41 and a reset working surface 42 for abutting against and connecting with the contact 3. The reset working surface 42 is recessed to the side away from the contact 3, and the contact 3 can move relative to the cam 4 to switch between the positioning working surface 41 and the reset working surface 42; the elastic element 5 is used to drive the contact 3 to abut against the cam 4.

[0053] Understandably, the rotating shaft 1 is fixedly connected to the carport and serves as the rotational support component of the resetter. It provides a central axis for the rotation of the sun visor frame body 2, and the sun visor is mounted on the sun visor frame body 2, ensuring that the sun visor can rotate stably around a fixed axis during the flipping process. At the same time, the rotating shaft 1 is relatively fixed to the cam 4, providing a basis for the movement of the contact element 3 on different working surfaces.

[0054] The cam 4 is equipped with a positioning working surface 41 and a reset working surface 42 that are connected to each other. The positioning working surface 41 is used to cooperate with the contact member 3 when the sun visor is flipped to a suitable angle. The elastic potential energy of the elastic member 5 restricts the rotation of the sun visor frame body 2, so that the sun visor is stably suspended. The reset working surface 42, under specific conditions, such as when the angle between the sun visor and the roof is about 15° to 30°, uses the elastic member 5 to guide the contact member 3 to move. The elastic member 5 releases the elastic potential energy to drive the sun visor frame body 2 to rotate and reset at a specific angle. At this time, the elastic member 5 gradually deforms and resets, the elastic restoring force gradually decreases, the clamping force is small, and the reset working surface 42 is concave away from the contact member 3 to form a downward slope. Under the action of the elastic member 5, the sun visor automatically resets without the need for the driver or passenger to continue to apply force. The driver or passenger can remove their hands in advance, thereby preventing hand pinching.

[0055] The sun visor frame body 2 is used to fix the sun visor and ensure its stable installation. The contact element 3 on the sun visor frame body 2 allows it to interact with the working surface of the cam 4. When the user operates the sun visor, the frame body drives the contact element 3 to move synchronously, causing the contact element 3 to move on different working surfaces of the cam 4, thereby realizing the sun visor's flipping adjustment, positioning and hovering, and automatic reset.

[0056] The elastic element 5 can keep the contact element 3 abutting against the working surface of the cam 4, and deforms when the contact element 3 moves from the reset working surface 42 to the positioning working surface 41, storing a large elastic potential energy to limit the rotation of the sun visor and achieve stable positioning; during the reset phase, as the contact element 3 moves towards the reset working surface 42, the elastic potential energy is released, providing a suitable reset force, which not only ensures the realization of automatic reset, but also reduces the risk of pinching hands.

[0057] When the user flips the sun visor downwards, the sun visor frame body 2, which is fixedly connected to the sun visor, rotates synchronously, and the contact element 3 on the frame body moves accordingly. At this time, the contact element 3 gradually moves from the reset working surface 42 of the cam 4 to the positioning working surface 41. During this process, the elastic element 5 deforms, and the elastic potential energy continuously increases. When the sun visor is flipped to the desired sun shading angle, the contact element 3 stably abuts against the positioning working surface 41. With the larger elastic potential energy at this time, it restricts the sun visor frame body 2 from continuing to rotate, allowing the sun visor to be stably suspended, meeting the user's adjustment needs for different sun shading angles.

[0058] After use, the user pushes the sun visor upwards to reset it. When the angle between the sun visor and the car roof reaches a preset angle, such as 30°, the contact element 3 disengages from the positioning working surface 41 and moves towards the reset working surface 42. As the contact element 3 moves, the elastic potential energy of the elastic element 5 is released, providing a thrust to the contact element 3. The contact element 3 continues to move along the reset working surface 42, driving the sun visor frame body 2 to rotate, thereby achieving automatic reset of the sun visor until it returns to its initial position.

[0059] During the sun visor adjustment phase, the positioning working surface 41 cooperates with the elastic element 5, which has a large elastic potential energy, to ensure that the sun visor can be stably suspended at any adjustment angle within the adjustment range, allowing users to adjust it as needed. During the reset phase, by setting the contact element 3 to switch working surfaces at a specific angle, the elastic element 5 continuously releases elastic potential energy to provide a stable reset thrust, ensuring that the sun visor automatically resets to its initial position.

[0060] Reference Figure 1 and Figure 2 In some embodiments, the cam 4 is sleeved on the rotating shaft 1 and fixedly connected to the rotating shaft 1.

[0061] It is understandable that the connection between the cam 4 and the rotating shaft 1 includes detachable fixed connections and non-detachable fixed connections. Detachable fixed connections include, but are not limited to, key connections, interference fits, screw connections, and pin connections. Non-detachable fixed connections include, but are not limited to, welding and bonding.

[0062] The cam 4 is fixed to the rotating shaft 1, improving the compactness of the resetter structure and making the entire resetter structure more streamlined, facilitating its integration into the sun visor assembly. The cam 4 is fixed to the rotating shaft 1 to ensure that the two always rotate synchronously, preventing movement deviations caused by relative slippage or loosening. During frequent rotation of the sun visor, the cam 4 accurately presents the positioning working surface 41 and the reset working surface 42 to the contact member 3 sequentially, allowing the contact member 3 to move along a set trajectory and under set conditions, ensuring stable and reliable positioning and reset actions of the sun visor.

[0063] In practical applications, cam 4 and shaft 1 can also be integrated into a single structure. This integrated structure simplifies the production process. It eliminates the need for separate machining and assembly of cam 4 and shaft 1, reducing parts turnover and assembly steps, effectively shortening the production cycle and improving production efficiency. Furthermore, cam 4 can be fixedly mounted to the carport, ensuring that cam 4 and shaft 1 remain relatively fixed.

[0064] Reference Figure 3 In some embodiments, the positioning working surface 41 and the reset working surface 42 are both disposed on one end face of the cam 4. The positioning working surface 41 is a plane, the reset working surface 42 is an arc surface, and the reset working surface 42 is recessed towards the other end of the cam 4.

[0065] The positioning working surface 41 is set as a plane. When the contact element 3 abuts, the contact area is large and stable. Combined with the large elastic potential energy of the elastic element 5, it can provide a reliable limiting effect, so that the sun visor can be steadily suspended at any adjustment angle. Even if the vehicle is bumpy and vibrating, it is not easy to shift, thus ensuring the stability of the sun visor function.

[0066] The reset working surface 42 is designed as an arc surface, forming a smooth downward slope, which allows the contact element 3 to have a certain amount of room to move, thereby allowing the elastic potential energy of the elastic element 5 to be released. When the sun visor is reset upward to a specific angle, as the contact element 3 moves from the flat surface to the arc surface, the elastic potential energy of the elastic element 5 is continuously and slowly released as the arc surface concaves, thereby controlling the reset force, facilitating the reaction of drivers and passengers, reducing the risk of pinching hands, and improving safety. At the same time, the shape of the arc surface guides the contact element 3 to move along a preset trajectory, ensuring a smooth and seamless reset process and enhancing the comfort of operation.

[0067] The working surfaces are concentrated on the same end face, resulting in a simpler structure and easier manufacturing. Furthermore, the presence of different working surfaces on the same end face, with the two working surfaces interconnected, allows the contact element 3 to smoothly transition between the two working surfaces, ensuring smooth and stable operation of the resetter.

[0068] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the sun visor resetter also includes a transmission component 6, which is fixedly connected to the contact component 3. One of the contact component 3 and the transmission component 6 is rotatably connected to the sun visor frame body 2. The elastic component 5 can drive the transmission component 6 to swing and drive the contact component 3 to move relative to the cam 4.

[0069] In this embodiment, the contact member 3 or the transmission member 6 is rotatably connected to the sunshade frame body 2, and the elastic member 5 uses the lever principle to transmit the force to the contact member 3.

[0070] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, one of the contact member 3 and the transmission member 6 is provided with a first connecting hole 66, and the sunshade resetter also includes a first fixing shaft 21, which is installed on the sunshade frame body 2 and disposed in the first connecting hole 66.

[0071] In this embodiment, the transmission member 6 and the contact member 3 are located at the two ends of the first fixed shaft 21, forming a lever structure with the first fixed shaft 21 as the fulcrum. The lever arm length of the transmission member 6 is greater than that of the contact member 3, meaning that a small thrust from the elastic member 5 can drive the contact to swing. In practical applications, the first connecting hole 66 can also be provided on the contact member 3 or the transmission member 6, which can also form a lever structure.

[0072] Reference Figure 3 and Figure 5 In some embodiments, the contact member 3 includes an extension 31 connected to the transmission member 6 and an action wheel 32 rotatably mounted on the extension 31, the circumferential surface of the action wheel 32 making rolling contact with the positioning working surface 41 or the reset working surface 42.

[0073] The rolling contact between the actuating wheel 32 and the working surface of the cam 4 reduces the friction between the contact element 3 and the cam 4 compared to sliding friction, making the sun visor flipping and resetting process smoother, while also reducing component wear and extending service life. The rolling contact ensures a tight fit between the actuating wheel 32 and the working surface of the cam 4, ensuring that the contact element 3 can follow the contour of the cam 4, achieving precise control of the sun visor's positioning and resetting actions, and avoiding displacement deviations or jamming caused by sliding.

[0074] In practical applications, the contact element 3 can be made of wear-resistant materials or have a special surface treatment to reduce frictional wear with the working surface of the cam 4.

[0075] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments, the transmission component 6 includes a first connecting rod 61 and a second connecting rod 65. The first end of the first connecting rod 61 is rotatably connected to the first end of the second connecting rod 65. The second ends of the first connecting rod 61 and the second ends of the second connecting rod 65 are respectively rotatably connected to the sunshade frame body 2. The contact member 3 is disposed at the second end of the second connecting rod 65. One end of the elastic member 5 abuts against the rod segment of the first connecting rod 61 and is used to drive the first connecting rod 61 to rotate.

[0076] The contact point between the elastic element 5 and the first connecting rod 61 is located on the rod segment rather than at the end point, ensuring a sufficiently large contact surface and stable force transmission. Through linkage transmission, the linear motion of the elastic element 5 is converted into oscillation, making the motion trajectory of the contact element 3 more closely match the contour curve of the cam 4. Especially in the arc-shaped area of ​​the reset working surface 42, the linkage mechanism can adaptively adjust its angle under the action of the elastic element 5, ensuring that the contact element 3 always maintains effective contact with the cam 4, improving the smoothness and reliability of the reset action. The double-link design can adapt to different internal space constraints of the sun visor by adjusting the rod length and hinge angle.

[0077] Reference Figure 5 and Figure 6 In some embodiments, the sun visor resetter further includes a second fixed shaft 22, which is installed on the sun visor frame body 2. The second fixed shaft 22 includes connecting portions 221 at both ends and limiting portions 222 between the connecting portions 221. The diameter of the connecting portions 221 is smaller than the diameter of the limiting portions 222. The first end of the first connecting rod 61 is provided with an opening 64, and the limiting portion 222 is limited within the opening 64. The two connecting portions 221 are respectively rotatably engaged with the side walls on both sides of the opening 64.

[0078] In this embodiment, the second connecting hole 62 is arranged around the second fixed shaft 22, that is, the first connecting rod 61 rotates around the first fixed shaft 21, providing a stable rotation fulcrum for the first connecting rod 61, preventing radial offset during force transmission, and ensuring the smoothness of the sun visor's flipping and resetting actions. The hole-shaft mating installation method results in a simple structure that facilitates production and assembly.

[0079] In addition, the diameter of the limiting part 222 is larger than that of the connecting part 221, and the first connecting rod 61 is connected to the connecting parts 221 at both ends of the limiting part 222. This can prevent the third connecting hole 63 from moving axially during rotation, restrict the circumferential movement of the first connecting rod 61 along the first fixed shaft 21, ensure that it always rotates stably around the first fixed shaft 21, and ensure the reliability of the transmission.

[0080] Reference Figure 1 and Figure 5 In some embodiments, the rotating shaft 1 passes through the opening 64.

[0081] Understandably, the first connecting rod 61 intersects with the rotating shaft 1 at the opening 64, facilitating contact with the elastic element 5. The opening 64 allows the first connecting rod 61 to be installed around the rotating shaft 1, avoiding interference between the rotating shaft 1 and the connecting rod's movement, resulting in a more compact structure and improved space utilization. The rotating shaft 1 passes through the opening 64 but is not fixedly connected, ensuring that the first connecting rod 61 can rotate freely around the first fixed shaft 21 within a preset working angle, unaffected by the rotation of the rotating shaft 1, thus guaranteeing the independence of the transmission element 6's movement. The opening 64 structure allows the first connecting rod 61 to be assembled after the rotating shaft 1 is installed, reducing restrictions on the installation sequence, making it particularly suitable for modular production scenarios and improving assembly efficiency.

[0082] Reference Figure 5 In some embodiments, the second end of the first connecting rod 61 is provided with a third connecting hole 63, the first end of the second connecting rod 65 is provided with a fourth connecting hole 67, and a pin 68 is provided through the third connecting hole 63 and the fourth connecting hole 67.

[0083] A pin 68 passes through the third connecting hole 63 and the fourth connecting hole 67, forming a stable and flexible rotating pair between the first connecting rod 61 and the second connecting rod 65. This rotatable connection via the pin 68 simplifies the structure, reduces production assembly difficulty and cost, and facilitates disassembly, inspection, or replacement of connecting rod components during later maintenance, thus improving maintainability.

[0084] Reference Figure 5 and Figure 6 In some embodiments, the first link 61 includes a first link segment 61a, a second link segment 61b, and a bent segment 61c connecting the first link segment 61a and the second link segment 61b. The end of the first link segment 61a away from the bent segment 61c is connected to the contact member 3, and the end of the second link segment 61b away from the bent segment 61c is rotatably connected to the second link 65. Specifically, the end of the first link segment 61a away from the bent segment 61c is provided with a second connecting hole 62, and the sunshade frame body 2 is provided with a second fixed shaft 22 that rotatably engages with the second connecting hole 62.

[0085] It is understandable that by setting the bent section 61c, with the first link 61 and the second link 65 having a relatively small length, a large gap is made between the second end of the first link 61 and the first end of the second link 65, and other structural components, such as the cam 4, can be set in between, making the structure more compact.

[0086] Reference Figure 5 and Figure 6In some embodiments, the sun visor frame body 2 includes a pad 23, which is disposed between the first fixed shaft 21 and the sun visor frame body 2. The pad 23 is used to adjust the distance between the second connecting rod 65 and the sun visor frame body 2. The thickness of the pad 23 can be increased or decreased according to actual assembly requirements to adjust the distance between the second connecting rod 65 and the sun visor frame body 2, compensate for component processing errors, ensure the relative position accuracy between the second connecting rod 65, the first connecting rod 61 and other components, and improve the assembly accuracy of the transmission system.

[0087] Reference Figure 1 In some embodiments, the elastic element 5 is a helical spring. The helical spring has a cylindrical structure and is arranged axially along the shaft 1, occupying a small radial space. The helical spring has good working stability, can stably extend and retract within its elastic limit, thus providing a stable thrust, and is not easily worn during operation, having a long service life.

[0088] Reference Figure 1 and Figure 2 In some embodiments, the sun visor resetter further includes a fixing sleeve 7, which is fixedly sleeved on the rotating shaft 1 and abuts against one end of the elastic member 5. The other end of the elastic member 5 is elastically connected to the transmission member 6. The fixing sleeve 7 is fixedly connected to the rotating shaft 1, providing a stable support base for the elastic member 5, so that the first end of the elastic member 5 will not be displaced when it is deformed by force.

[0089] Reference Figure 1 In some embodiments, the relative position of the fixed sleeve 7 and the rotating shaft 1 is adjustable to adjust the extension and retraction stroke of the elastic element 5. It is understood that the adjustable relative position of the fixed sleeve 7 and the rotating shaft 1 is only applicable during production and maintenance; during use, the relative position of the fixed sleeve 7 and the rotating shaft 1 is fixed. By adjusting the relative position of the fixed sleeve 7 and the rotating shaft 1, the initial compression or tension state of the elastic element 5 is adjusted, thereby controlling its extension and retraction stroke. When the fixed sleeve 7 moves along the rotating shaft 1, the preload of the elastic element 5 changes accordingly. For example, reducing the distance between the fixed sleeve 7 and the movable sleeve 8 increases the compression of the elastic element 5, allowing for a greater release of elastic force during reset; conversely, increasing the distance reduces the reset force. By adjusting the position of the fixed sleeve 7, the personalized needs of different users for the reset speed and force of the sun visor can be flexibly adapted, ensuring that the sun visor can be stably suspended and automatically reset with appropriate force during positioning and reset, avoiding hand pinching due to excessive elastic force or reset failure due to insufficient elastic force.

[0090] Different car models have different sun visor designs and user habits, resulting in varying requirements for the elastic parameters of the resetter. The adjustable design of the fixing sleeve 7 allows the same resetter to adapt to diverse needs. Automakers no longer need to develop separate resetters for different models; they can adjust the performance of the elastic element 5 simply by adjusting the position of the fixing sleeve 7. This enables the product to be produced universally, reducing R&D and production costs, shortening product development cycles, and improving market responsiveness.

[0091] In the production and assembly process, the adjustable fixing sleeve 7 enhances the flexibility of the installation process. Assembly personnel can adjust the position of the fixing sleeve 7 on-site according to actual assembly needs, quickly calibrating the extension and contraction stroke of the elastic element 5, reducing rework and debugging time caused by initial parameter deviations of the elastic element 5. Simultaneously, this design reduces the stringent requirements for component machining precision. Even if components such as the rotating shaft 1 and the elastic element 5 have certain dimensional tolerances, these can be compensated for by adjusting the position of the fixing sleeve 7, ensuring consistent product performance and improving production efficiency and yield. Furthermore, if the performance of the elastic element 5 deteriorates during long-term use, its original reset force can be restored by adjusting the fixing sleeve 7, without replacing the entire elastic element 5 or the resetter. This simplifies maintenance and improves product durability and user satisfaction.

[0092] In practical applications, the connection between the fixed sleeve 7 and the rotating shaft 1 can also adopt other detachable fixed connection methods, including but not limited to key connection, interference fit, screw connection, and pin connection.

[0093] Reference Figure 1 and Figure 7 In some embodiments, the sunshade resetter further includes a movable sleeve 8, which is movably sleeved on the rotating shaft 1 and abuts against the other end of the elastic member 5. The side of the movable sleeve 8 away from the elastic member 5 abuts against the transmission member 6.

[0094] The cooperation between the elastic element 5 and the movable sleeve 8 provides excellent cushioning and shock absorption during the operation of the sun visor. When the contact element 3 switches between the working surfaces of the cam 4, the movable sleeve 8, cushioned by the elastic element 5, effectively reduces the impact, preventing rigid collisions between components and thus preventing wear and noise caused by collisions. This effectively extends the service life of the resetter components and reduces product failure rate and after-sales maintenance costs. Simultaneously, the smooth cushioning process makes the sun visor's flipping and resetting actions smoother, improving user comfort.

[0095] Reference Figure 1 and Figure 7In some embodiments, the movable sleeve 8 includes a support portion 81 and a contact portion 82. The support portion 81 is sleeved on the rotating shaft 1, and the inner wall of the support portion 81 is slidably connected to the rotating shaft 1. One end of the support portion 81 extends into the other end of the elastic member 5 to support the elastic member 5. The other end of the elastic member 5 abuts against one side of the contact portion 82, and the other side of the contact portion 82 abuts against the transmission member 6.

[0096] The inner wall of the support portion 81 is slidably connected to the rotating shaft 1, forming an axial guide to ensure that the movable sleeve 8 slides smoothly along the rotating shaft 1. The outer wall of the support portion 81 provides support for the elastic element 5, adapts to the inner diameter of the elastic element 5, prevents the elastic element 5 from shifting during compression or tension, ensures that the elastic force acts axially on the transmission component 6, and improves the reliability of the reset function. The contact portion 82 is used to limit the position of the movable sleeve 8 and the elastic element 5, preventing the elastic element 5 from sliding out of the support portion 81 and ensuring the reliability of the connection.

[0097] Reference Figure 2 and Figure 7 In some embodiments, a slope 821 is provided on the other side of the contact portion 82, and the slope 821 is in contact with the transmission member 6. The slope 821 of the contact portion 82 is in contact with the transmission member 6, and the contact surface is large, which ensures the stability of force transmission and ensures a smooth sunshade reset process.
