Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. 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. Therefore, they should not be construed as limitations on this utility model.

The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] In the description of this utility model, the directions such as up, down, front, back, left, and right are referred to as the position of the car in the vehicle's O-XYZ coordinate system. The origin O coincides with the center of mass of the vehicle. The front end refers to the X direction parallel to the ground pointing forward, the rear end refers to the X direction parallel to the ground pointing backward, the left side refers to the Y direction parallel to the ground pointing to the driver's left, the right side refers to the Y direction parallel to the ground pointing to the driver's right, the upper end refers to the Z direction passing through point O pointing upward, and the lower end refers to the Z direction passing through point O pointing downward.

[0025] In related technologies, sun visors are commonly used functional components in vehicles. Due to limitations in interior space and the range of sun visor rotation, the width of the sun visor cannot be made too large, otherwise it will affect the driver's visibility during rotation. However, if the width of the sun visor is moderate, it will not completely block sunlight, resulting in some sunlight still being glaring.

[0026] Reference Figures 1 to 3As shown, a first aspect of this utility model provides a sunshade, which includes a first plate 100 and a second plate 200 connected to the first plate 100. The second plate 200 is configured to move relative to the first plate 100 from a retracted position to an extended position along a preset direction to increase the coverage area of ​​the sunshade. One of the first plate 100 and the second plate 200 includes a locking groove 110, which includes a plurality of slots 111 sequentially distributed along the preset direction. The other of the first plate 100 and the second plate 200 includes a plurality of posts 210 sequentially distributed along the preset direction. When the second plate 200 is in the retracted position, at least some of the posts 210 engage with the corresponding slots 111 and follow the second plate 200 from the retracted position. When the device moves toward the unfolded position, at least some of the locking posts 210 that are engaged in the locking slot 111 disengage from the locking slot 110, thereby reducing the number of locking posts 210 engaged in the locking slot 110. By reducing the number of locking posts 210 in the locking slot 110, the locking force between the locking posts 210 and the locking slot 110 changes, thus providing force feedback for the movement of the second plate 200 and improving user comfort. At the same time, in the retracted position, a sufficient number of locking posts 210 cooperate with the locking slot 110, increasing the connection force between the second plate 200 and the first plate 100, making it less likely for the second plate 200 to separate from the first plate 100, further improving the connection reliability between the second plate 200 and the first plate 100, and making the use of the sunshade more reliable.

[0027] In this embodiment, the first plate 100 is rectangular in shape and is rotatably connected to the vehicle body. It can provide sunshade in front of and to the sides of the vehicle by rotating around the vehicle body. The second plate 200 is also generally rectangular in shape and can move relative to the first plate 100 from a retracted position to an extended position along a preset direction. The preset direction refers to the direction in which the second plate 200 moves from the retracted position to the extended position; the direction in which the second plate 200 moves from the extended position to the retracted position is the opposite of the preset direction. The retracted position refers to the position of the second panel 200 when the sun visor's shading area is at its minimum. For example, when only the first panel 100 provides shading and the second panel 200 provides virtually no shading, the sun visor's shading area is at its minimum. In this case, the second panel 200 can be considered to be located within the first panel 100, and the second panel 200 is in the retracted position. Another example is when a portion of the second panel 200 and the first panel 100 provide shading together, but the portion of the second panel 200 that provides shading is difficult to extend into the first panel 100. In this case, the sun visor's shading area is at its minimum, and the position of the second panel 200 is the retracted position. The extended position refers to the position of the second panel 200 when the sun visor's shading area is at its maximum. Specifically, the maximum shading area of ​​the sun visor means that the second panel 200 extends the maximum shading area relative to the first panel 100 along a preset direction. Therefore, when the second panel 200 moves to its limit position relative to the first panel 100 along the preset direction (without separating from the first panel 100), the second panel 200 is in the extended position. In the specific sunshade structure, the first plate 100 provides sunshade through the covering surface formed by the length and width directions of the first plate 100. The preset direction can be the length direction of the first plate 100 or the width direction of the first plate 100. In other words, the second plate 200 can increase the covering area along the length direction of the first plate 100 or along the width direction of the first plate 100. Alternatively, the second plate 200 can increase the covering area along both the length and width directions of the first plate 100.

[0028] Specifically, the first plate 100 includes a locking groove 110, which includes multiple slots 111. The second plate 200 includes multiple locking posts 210. The locking posts 210 are elastically engaged with the slots 111. When the second plate 200 is not driven by an external force, the locking posts 210 are engaged in the corresponding slots 111, thus achieving the engagement. The second plate 200 is engaged with the first plate 100. When the second plate 200 is driven by an external force and moves from the retracted position to the unfolded position, the locking posts 210 and the slots 111 undergo elastic deformation, thereby causing the locking posts 210 to move from one slot 111 to the next slot 111 along a preset direction, thus enabling the second plate 200 to move relative to the first plate 100 along the preset direction. It is understandable that as the second plate 200 moves from the retracted position to the unfolded position, some of the locking posts 210 move from the original slot 111 to the new slot 111 along a preset direction, while another number of locking posts 210 separate from the slot 111 along the preset direction and move outside the locking slot 110. The locking posts 210 outside the locking slot 110 no longer provide locking force for the first plate 100 and the second plate 200. Therefore, the total locking force between the second plate 200 and the first plate 100 is reduced. In other words, during the process of the second plate 200 moving from the retracted position to the unfolded position, the total locking force between the second plate 200 and the first plate 100 decreases step by step, forming force feedback. Users can identify the position of the second plate 200 relative to the first plate 100 through the change in feedback force, thereby adjusting the relative position of the second plate 200 and the first plate 100 without visual adjustment, making it more convenient to use. For example, during vehicle operation, the vehicle's direction of travel may change. There might be a situation where there is no direct sunlight when the vehicle starts moving, but direct sunlight appears after the direction of travel changes. In this case, the user needs to adjust the sun visor for sun protection. If the user adjusts the sun visor directly visually, it will affect normal driving. In this embodiment, the user can adjust the sun visor through force feedback, allowing the user's vision to focus on the road conditions, improving driving safety and user comfort. From another perspective, when the second plate 200 is in the retracted position, there are a sufficient number of locking posts 210 and corresponding locking slots 111 between the second plate 200 and the first plate 100, maximizing the total locking force between the second plate 200 and the first plate 100, making the connection between the second plate 200 and the first plate 100 more reliable. As another implementation, the first plate 100 includes multiple locking posts 210, and the second plate 200 includes locking slots 110. Furthermore, the multiple locking posts 210 are arranged along a preset direction, and they also serve a guiding function to guide the second plate 200 to move in the preset direction or the opposite direction.

[0029] It is understandable that by changing the total coverage area through the second plate 200, the sun visor can adapt to different types of light by covering different areas, thus improving user comfort. Through the elastic engagement of multiple locking posts 210 and multiple locking slots 111, the second plate 200 extends the coverage area of ​​the first plate 100 to more levels. Furthermore, at different levels, different numbers of locking posts 210 and locking slots 111 engage, thereby providing users with different force feedback and further improving user comfort.

[0030] Reference Figure 1 As shown, in some specific embodiments of this utility model, in the retracted position, all the locking posts 210 are located within at least a portion of the locking slots 111.

[0031] In this embodiment, the number of locking posts 210 equals the number of locking slots 111. During the movement of the second plate 200 relative to the first plate 100 from the retracted position to the extended position along a preset direction, if one locking post 210 moves into a new locking slot 111 along the preset direction, the other locking post 210 separates from the locking slot 110, reducing the locking force between the second plate 200 and the first plate 100. Therefore, each time the same locking post 210 moves into a new locking slot 111 along the preset direction, the locking force between the second plate 200 and the first plate 100 decreases, and the shading area of ​​the sun visor increases accordingly. In other words, different shading areas of the sun visor correspond to different locking forces, and along the preset direction, the larger the shading area of ​​the sun visor, the smaller the locking force. Users can adjust the shading area of ​​the sun visor based on the force feedback between the second plate 200 and the first plate 100, eliminating the need for users to focus on the size of the sun visor and allowing them to concentrate their vision on the front of the vehicle, thus reducing safety risks. As another implementation, in the retracted position, all the locking posts 210 are located within a portion of the locking slots 111, or in the retracted position, a portion of the locking posts 210 are located within all the locking slots 111.

[0032] Reference Figure 1 As shown, in some specific embodiments of this utility model, in the retracted position, all the locking posts 210 are connected as a single structure along a preset direction.

[0033] In this embodiment, all the locking posts 210 are connected as a single structure along a preset direction, resulting in higher overall connection strength and more reliable use. When the second plate 200 is driven by an external force, all the locking posts 210 will distribute the external force evenly, making the force on each locking post 210 more uniform and avoiding stress concentration, which is more conducive to the long-term use of the locking posts 210. Furthermore, after multiple locking posts 210 form a single structure, the guidance of multiple locking posts 210 is more stable, making it easier for multiple locking posts 210 to pass through the locking groove 110 together. That is, the movement of the second plate 200 relative to the first plate 100 is more stable, resulting in higher comfort of use.

[0034] Reference Figure 1 As shown, in some specific embodiments of this utility model, multiple slots 111 are connected to the outside along a preset direction. As the second plate 200 moves from the retracted position to the unfolded position, the locking post 210 can disengage from the locking slot 110 and move to the outside. In this embodiment, the first plate 100 includes the locking slot 110, and the second plate 200 includes multiple locking posts 210. After the locking post 210 disengages from the locking slot 110, it moves directly to the outside. The locking post 210 disengages from the locking slot 110 within the first plate 100 through the space outside the first plate 100, allowing the locking slot 110 to extend as far as possible within the first plate 100 along the preset direction. This allows the second plate 200 to extend beyond the first plate 100, resulting in a larger coverage area for the sun visor and thus improving the sun visor's sun-shading effect.

[0035] Reference Figure 1 As shown, in some specific embodiments of this utility model, one of the first plate 100 and the second plate 200 further includes a clearance groove 120. The clearance groove 120 connects the plurality of locking slots 111 to the outside. As the second plate 200 moves from the retracted position to the unfolded position, the locking post 210 can disengage from the locking slot 110 and move into the clearance groove 120. In this embodiment, the first plate 100 includes the locking slot 110 and the clearance groove 120, and the second plate 200 includes a plurality of locking posts 210. After the locking post 210 disengages from the locking slot 110, the locking post 210 moves into the clearance groove 120. The clearance groove 120 covers the locking post 210, preventing it from being exposed and affecting the aesthetics of the sun visor, making the sun visor's appearance more flat and beautiful.

[0036] Reference Figure 1 As shown, in some specific embodiments of this utility model, the first plate 100 further includes a first limiting part 130, and the second plate 200 further includes a second limiting part 220. When the second plate 200 is in the unfolded position, the second limiting part 220 abuts against the first limiting part 130 to restrict the movement of the second plate 200 along a preset direction.

[0037] It should be noted that when a user applies an external force along a preset direction to the second plate 200, the second plate 200 moves relative to the first plate 100 along the preset direction to increase the sunshade's coverage area. Different users have different force application habits, and if the applied force is too large, the second plate 200 may separate directly from the first plate 100, affecting normal use. Therefore, in this embodiment, the first limiting part 130 and the second limiting part 220 abut against each other to limit the first plate 100 and the second plate 200. Even when the user applies excessive external force, the second plate 200 will be stopped at the abutment position of the first limiting part 130 and the second limiting part 220, preventing the first plate 100 from separating from the second plate 200. This ensures that the sunshade's function of increasing the coverage area works normally, improving the user experience.

[0038] Reference Figure 1 As shown, in some specific embodiments of this utility model, the first plate 100 includes a locking groove 110, the second plate 200 includes a plurality of locking posts 210, and the second limiting part 220 includes a limiting post. The limiting post and the plurality of locking posts 210 are distributed along a preset direction. When the second plate 200 is in the retracted position, the limiting post is locked into the corresponding locking groove 111, and moves with the second plate 200 from the retracted position to the unfolded position. The limiting post moves in the locking groove 110 to lock into other locking grooves 111.

[0039] It is understandable that the limiting post serves both a limiting function and an elastic engagement function with the slot 111, thus restricting the relative position of the first plate 100 and the second plate 200 while increasing the locking force between them. Furthermore, by combining multiple functions with a single limiting post, the limiting structure between the first plate 100 and the second plate 200 is simplified, reducing manufacturing difficulty and cost.

[0040] Reference Figure 1 As shown, in some specific embodiments of this utility model, the first plate 100 further includes a relief groove 120, a locking groove 110, and the relief groove 120 are interconnected along a preset direction. The relief groove 120 is used to avoid the locking post 210. The second limiting part 220 includes a stepped surface, which is disposed between the relief groove 120 and the locking groove 110. When the second plate 200 is in the unfolded position, the limiting post abuts against the stepped surface in the locking groove 110.

[0041] It is understandable that by avoiding the locking post 210 through the avoidance groove 120, the locking post 210 can move into the avoidance groove 120 after disengaging from the locking groove 110, so as to realize the force feedback between the first plate 100 and the second plate 200. At the same time, the avoidance part blocks the locking post 210, making the sun visor more aesthetically pleasing overall.

[0042] In this embodiment, a stepped surface is formed between the clearance groove 120 and the locking groove 110, and the stepped surface is located within the locking groove 110. The limiting post and the locking post 210 are arranged coaxially, with one end of the limiting post longer than one end of the locking post 210. The extended portion of the limiting post will abut against the stepped surface, while the locking post 210 will directly enter the clearance groove 120 without contacting the stepped surface, thereby achieving the abutment and limiting of the first limiting part 130 and the second limiting part 220. The end face of the limiting post also abuts against the groove wall of the locking groove 110, thus essentially determining the relative position of the limiting post and the locking groove 110. This ensures that the locking post 210 does not abut against the stepped surface but directly enters the clearance groove 120. Therefore, the limiting post also serves to position the relative position of the locking post 210 and the clearance groove 120.

[0043] Reference Figure 1 As shown, in some specific embodiments of this utility model, the first plate 100 includes a locking groove 110, the second plate 200 includes a plurality of locking posts 210, the first plate 100 includes a first part 140, a second part 150 and a third part 160 connected in sequence, the first part 140, the second part 150 and the third part 160 together form an installation groove 170, and the side wall of the first part 140 and / or the third part 160 forming the installation groove 170 defines the locking groove 110.

[0044] In this embodiment, the sidewalls of the mounting groove 170 formed by the first part 140 and the third part 160 both define locking grooves 110. That is, the first plate 100 includes two sets of locking grooves 110 disposed within the mounting groove 170 and arranged opposite each other. The second plate 200 includes a second main plate 230 and two sets of posts. The two sets of posts are respectively disposed on opposite sides of the second main plate 230. Each set of posts includes multiple locking posts 210. The two sets of posts are respectively engaged with the two sets of locking grooves 110 to achieve elastic engagement and limiting of the first plate 100 and the second plate 200. At the same time, both opposite sides of the first plate 100 and the second plate 200 are engaged and limited, making the movement of the second plate 200 relative to the first plate 100 more stable and more convenient to use.

[0045] Reference Figure 1 As shown, in some specific embodiments of this utility model, the second plate 200 includes a second main plate portion 230 and a latching portion 240. The latching portion 240 is disposed on the second main plate portion 230 and is used for the user to apply external force in a preset direction or the opposite direction of the preset direction. The user can directly apply external force to the second plate 200 through the latching portion 240, which makes it more convenient for the user to apply force and improves the user's comfort.

[0046] Reference Figure 1As shown, in some specific embodiments of this utility model, the second plate 200 includes a second main plate portion 230 and a fastening portion 240. The second main plate portion 230 is disposed in the mounting groove 170 and has an exposed surface for being exposed to the outside world. The fastening portion 240 is disposed on the exposed surface so that the user can apply external force in a preset direction or the opposite direction of the preset direction.

[0047] In this embodiment, the latching part 240 is a groove, which allows the user's fingers to be inserted to increase the space for the user to apply force, making it easier for the user to apply external force to the second plate 200. The side of the second main plate 230 away from the second part 150 of the first plate 100 is the exposed surface. Furthermore, two sets of posts are respectively provided on two opposite sides of the second main plate 230. As another embodiment, the latching part 240 can also be a pull ring, with the second main plate 230 and the pull ring connected sequentially along a preset direction. The pull ring allows the user's fingers to pass through for pushing and pulling.

[0048] Reference Figure 1 As shown, a second aspect of this utility model proposes a vehicle, which includes a vehicle body and a sun visor as described in the first aspect embodiment, with the first visor 100 rotatably connected to the vehicle body. It is understood that using the sun visor of the first aspect embodiment in a vehicle can improve user comfort and thus enhance market competitiveness. The sun visor is rotatably connected to the vehicle body, allowing it to rotate to provide sun shading both in front of and to the side of the vehicle.

[0049] In this embodiment, the vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large semi-trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
