[0043] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of 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.

[0044] The following is for reference. Figures 1-9 This describes a sunshade device 100 according to an embodiment of the present utility model.

[0045] like Figures 1 to 4As shown, the sunshade device 100 according to an embodiment of the present invention includes: a fixed base 10, a connecting shaft 20, a sunshade surface 30, a frame strip 40, and a driving member 50. The connecting shaft 20 is disposed on the fixed base 10; the sunshade surface 30 is located on one side of the connecting shaft 20 and is configured to be foldable to form multiple layer structures 31; there are multiple frame strips 40, which are correspondingly arranged with the multiple layer structures 31, each frame strip 40 is located between two adjacent layer structures 31 and is connected to one of the two adjacent layer structures 31, the multiple frame strips 40 are rotatably connected to the connecting shaft 20, and the outermost one is the active strip 401; the driving member 50 is connected to the active strip 401 to drive the active strip 401 to move around the axis of the connecting shaft 20, so that the sunshade surface 30 can be opened or folded up.

[0046] The shading surface 30 can refer to a component of a layered structure, and can be, but is not limited to, shading fabric, shading film, etc. The shading surface 30 is constructed to be foldable, forming multiple layered structures 31 (see...). Figure 3 The term 30 can refer to the fact that the sunshade surface 30 can be folded into a fan-like structure, and the sunshade surface 30 can form two layer structures 31 each time it is folded.

[0047] The number of skeleton strips 40 can be equal to and correspond one-to-one with the number of layer structures 31. Each skeleton strip 40 connects to one layer structure 31, thereby supporting multiple layer structures 31. The axial direction of the connecting shaft 20 can be referenced. Figure 1 and Figure 2 The up and down directions.

[0048] When the sunshade device 100 is not in use, the sunshade device 100 can be completely folded up (see...). Figure 1 The sunshade surface 30 is folded up completely. When the sunshade device 100 is used, the drive unit 50 is connected to the drive bar 401, which drives the drive bar 401 to rotate around the axis of the connecting shaft 20, as shown in the reference. Figure 1 and Figure 4 That is, the active bar 401 is driven to rotate counterclockwise, and the active bar 401 drives the multiple layers 31 of the sunshade surface 30 to open, while the remaining skeleton bars 40 open with the sunshade surface 30; when the sunshade device 100 needs to be retracted, the driving member 50 drives the active bar 401 to rotate clockwise, pushing the multiple skeleton bars 40 to contact each other, thereby retracting the sunshade surface 30 and restoring it to the folded multiple layers 31.

[0049] According to the embodiment of the present invention, the sunshade device 100, by adopting the above-described structure, allows multiple frame bars 40 to rotate around the connecting shaft 20 to open the sunshade surface 30, and to retract the sunshade surface 30 by rotation, forming a fan-like structure for opening or retracting the sunshade surface 30. The opening or retraction method of the entire sunshade device 100 is relatively simple and easy to operate, which is beneficial to improving the user experience. Moreover, the structure of the sunshade device 100 is relatively simple. When applied to a vehicle 1000, it does not require a vertical support pole or other structure to support the sunshade device 100. The sunshade device 100 can be fixed to the frame 220 of the vehicle 1000 by the fixing seat 10, which can reduce the installation position and simplify the installation structure, thereby reducing damage to the original vehicle.

[0050] In some embodiments of this utility model, such as Figure 2 , Figure 5 and Figure 6 ( Figure 6 As shown in the figure (the gear structure of the reduction gear mechanism 503 is omitted), the driving component 50 includes a motor 501, a clutch 502 and a reduction gear mechanism 503. The motor 501 is mounted on the fixed base 10. The input shaft 5031 of the reduction gear mechanism 503 is connected to the motor shaft 5012 of the motor 501 through the clutch 502, and the output shaft 5032 of the reduction gear mechanism 503 is connected to the drive bar 401.

[0051] In the above technical solution, the motor 501 drives the drive bar 401 to rotate through the reduction gear mechanism 503, which increases the output torque to the drive bar 401, which is beneficial for driving multiple skeleton bars 40 to rotate around the connecting shaft 20, reducing the power requirement of the motor 501 and improving the stability of the entire device. The motor shaft 5012 of the motor 501 and the input shaft 5031 of the reduction gear mechanism 503 are linked by the clutch 502. This allows the clutch 502 to cut off the power transmission between the motor 501 and the reduction gear mechanism 503 by slipping or disengaging when the drive component 50 is overloaded, preventing the motor 501 and the reduction gear mechanism 503 from being damaged due to excessive load, and thus extending their service life.

[0052] Optionally, the reduction gear mechanism 503 is a multi-stage planetary gear reduction mechanism. This type of reduction gear mechanism 503 can output greater torque, has a more compact structure, and helps to reduce the size of the sunshade device 100.

[0053] Optionally, clutch 502 is an electromagnetic clutch. Using this type of clutch 502 allows for precise control, rapid response, and easy automation. (Refer to...) Figure 6Optionally, the clutch 502 may include an input disc 521 and an output disc 522, which may be engaged or disengaged from each other. The input disc 521 is connected to the motor shaft 5012, and the output disc 522 is connected to the input shaft 5031.

[0054] In some embodiments of this utility model, such as Figure 6 As shown, a receiving space 20b is formed inside the connecting shaft 20 to form a housing for accommodating the reduction gear mechanism 503, which is disposed within the receiving space 20b.

[0055] In the above technical solution, the connecting shaft 20 can not only provide multiple mounting positions for the skeleton strips 40, but also serve as the housing of the reduction gear mechanism 503 and provide mounting positions for the reduction gear mechanism 503. This structure allows the reducer formed by the connecting shaft 20 and the reduction gear mechanism 503 to be cylindrical, with a smaller volume, which can further save space and reduce the volume of the sunshade device 100.

[0056] In some embodiments of this utility model, such as Figure 2 , Figure 5 and Figure 6 As shown, the clutch 502 is provided with an operating shaft 5021. The operating shaft 5021 is connected in parallel with the input shaft 5031 of the reduction gear mechanism 503 through a gear. The outer shell of the clutch 502 is provided with an operating port 5022. One end of the operating shaft 5021 is located near the operating port 5022 and is provided with a spline sleeve 5023.

[0057] In case of power outages or other special circumstances, a dedicated rocker arm with a splined shaft head can be inserted into the splined sleeve 5023 inside the operating port 5022. The splined shaft head and the operating shaft 5021 achieve power linkage. The operating shaft 5021 meshes with the input shaft 5031 of the reduction gear mechanism 503. When the clutch 502 is not in operation, it is disengaged from the motor shaft 5012 of the motor 501. Rotating the rocker arm by external force can drive the input shaft 5031 of the reduction gear mechanism 503 to rotate, thereby manually opening or retracting the sunshade surface 30. In other words, the sunshade device 100 can be opened or retracted by electric drive or manually, meeting the needs of various scenarios.

[0058] Optionally, the operating shaft 5021 can be arranged at a 90-degree angle to the input shaft 5031 of the reduction gear mechanism 503. With this arrangement, the spline sleeve 5023 at one end of the operating shaft 5021 is located on the side of the reduction gear mechanism 503, which facilitates manual operation.

[0059] In some embodiments of this utility model, such as Figure 5 , Figure 6 and Figure 8 As shown, the connecting shaft 20 is provided with an annular groove 20a, and the skeleton strip 40 is provided with a snap-fit ​​arm 41, which is rotatably disposed in the annular groove 20a.

[0060] The skeleton strip 40 and the snap-fit ​​arm 41 can collectively form a structure similar to a tuning fork. The snap-fit ​​arm 41 can be an arc-shaped arm, which, in conjunction with the annular groove 20a, allows the skeleton strip 40 to rotate on the connecting shaft 20. The structure is relatively simple and improves the installation stability between the skeleton strip 40 and the connecting shaft 20. (Refer to...) Figure 8 The connecting shaft 20 may be provided with multiple slip rings, and each slip ring has an annular groove 20a.

[0061] Optionally, at least two snap-fit ​​arms 41 are provided on the skeleton strip 40 in the axial direction of the connecting shaft 20. That is, the skeleton strip 40 and the connecting shaft 20 can cooperate with the annular groove 20a through at least two snap-fit ​​arms 41, thereby improving the support stability of the skeleton strip 40 on the connecting shaft 20 and improving the connection strength between the skeleton strip 40 and the connecting shaft 20.

[0062] In some embodiments of this utility model, such as Figure 9 As shown, the sunshade device 100 includes a housing 60, a fixing base 10, a connecting shaft 20, a sunshade surface 30, a frame bar 40, and a driving member 50 disposed inside the housing 60, and the end of the sunshade surface 30 away from the driving bar 401 is connected to the housing 60.

[0063] The housing 60 provides the necessary installation space for the mounting base 10, connecting shaft 20, sunshade surface 30, frame bar 40, and drive component 50, and also provides protection against damage to these components from external impacts. The end of the sunshade surface 30 furthest from the drive bar 401 is connected to the housing 60, thus fixing that end and allowing the drive bar 401 to drag the sunshade surface 30 to fully open.

[0064] Optionally, the shell 60 can be a shell structure with one end open, and the frame strip 40 can drive the sunshade surface 30 to open outward from the open position of the shell 60.

[0065] Alternatively, the housing 60 can be a shell structure that is open at both ends in the width direction. This structure can save material for the housing 60 and reduce its weight, thereby reducing the weight of the entire sunshade device 100.

[0066] In some embodiments of this utility model, such as Figure 8As shown, the mounting base 10 is provided with a first wire passage hole 10a, and the housing 60 is provided with a second wire passage hole. The second wire passage hole and the first wire passage hole 10a are correspondingly arranged. The wiring harness assembly 5011 of the motor 501 passes through the first wire passage hole 10a and the second wire passage hole. The wiring harness assembly 5011 can electrically connect the motor 501 and the clutch 502. When the sunshade device 100 is in use, after receiving the control command to open the sunshade surface 30, the external controller can send the control command to the motor 501 and the clutch 502 through the wiring harness assembly 5011, and provide power to the motor 501 and the clutch 502, thereby controlling the sunshade surface 30 to open or close.

[0067] In some embodiments of this utility model, such as Figure 8 As shown, the skeleton strip 40 includes a connecting part 4001 and an extension part 4002 connected together. The connecting part 4001 is connected to the connecting shaft 20. In the length direction of the skeleton strip 40, the length of the connecting part 4001 is less than the length of the extension part 4002. In the axial direction of the connecting shaft 20, the width of the connecting part 4001 gradually decreases, and the width of the connecting part 4001 is greater than the width of the extension part 4002.

[0068] Since the entire sunshade surface 30 is supported on the connecting shaft 20 by one end of the frame strip 40, it has a cantilever structure. The connecting part 4001 of the frame strip 40 with this structure is the foundation and main stress point of the entire frame strip 40, bearing most of the pressure from the sunshade surface 30. The wider connecting part 4001 can provide stronger support, ensuring that the sunshade surface 30 maintains a stable shape when open and is not easily deformed or bent. The extension part 4002 is smaller in width than the connecting part 4001, which reduces the overall weight while ensuring a certain level of support, and also provides some flexibility at the edges of the sunshade surface 30, allowing it to better adapt to different stress conditions and improve the overall stability and reliability of the assembly formed by the sunshade surface 30 and the frame strip 40.

[0069] In some embodiments of this utility model, such as Figure 8 As shown, some of the multiple skeleton bars 40 are driven bars 402, and the rest are support bars 403. At least one support bar 403 is provided between any two adjacent driven bars 402. The thickness of the support bar 403 is less than the thickness of the driven bar 402. The thickness of the driven bar 402 is less than or equal to the thickness of the driving bar 401. In the axial direction of the connecting shaft 20, the width of the support bar 403 is less than the width of the driven bar 402.

[0070] In the above technical solution, while ensuring good support for the sunshade surface 30, the overall weight of multiple skeleton strips 40 can be reduced by using thinner support strips 403, the force exerted by multiple skeleton strips 40 on the connecting shaft 20 can be reduced, and the overall thickness of the sunshade surface 30 when it is in the retracted state can also be reduced, which is conducive to reducing the volume of the entire sunshade device 100 and facilitating the arrangement of the sunshade device 100 on the vehicle 1000.

[0071] Optionally, the thickness of the support bar 403 is half the thickness of the driven bar 402.

[0072] In some embodiments of this utility model, such as Figure 2 and Figure 8 As shown, the fixing base 10 can be a U-shaped structure, and the connecting shaft 20 is located inside the fixing base 10. With this structure, the rear side of the fixing base 10 can be fixed to the frame 220, thereby having a large contact surface with the frame 220, improving the connection stability and reliability of the two, and providing stable support for the entire sunshade device 100. On the other hand, the upper and lower ends of the connecting shaft 20 can be connected to the upper and lower ends of the fixing base 10, which also improves the connection stability and reliability of the connecting shaft 20 on the fixing base 10.

[0073] In some embodiments of this utility model, the sunshade surface 30 can be, but is not limited to, fabric, composite material, etc.

[0074] In some embodiments of this invention, the sunshade surface 30 may be made of a translucent or selectively transparent material. Optionally, the surface of the sunshade surface 30 may have a louvered texture.

[0075] In some embodiments of this invention, the sunshade surface 30 is bonded to multiple frame strips 40. This connection method is relatively simple and easy to manufacture. For example, the sunshade surface 30 can be bonded to the upper surface of the multiple frame strips 40 using an adhesive that is UV-resistant and crack-resistant.

[0076] In some embodiments of this invention, the surface of the sunshade surface 30 is provided with an anti-ultraviolet coating. With this design, the sunshade surface 30, when opened, can reflect harmful ultraviolet rays, creating a cool, shaded area below the sunshade surface 30, which is beneficial to human health.

[0077] The vehicle 1000 of this utility model embodiment is described below with reference to the accompanying drawings.

[0078] like Figure 10 and Figure 11As shown, a vehicle 1000 according to an embodiment of the present invention includes: a vehicle body 200 and a sunshade device 100 of any of the preceding embodiments. The vehicle body 200 includes a body 210 and a frame 220. The body 210 has an opening 2101, and the frame 220 is disposed inside the body 210. The sunshade device 100 is disposed inside the body 210 and connected to the frame 220, and the sunshade device 100 can be closed within the opening 2101.

[0079] Currently, most sunshades on the market are fixed to the outside of the vehicle body via an installation structure. When using the sunshade, the extension pole of the sunshade component is pulled outwards and supported on the ground. During use, there is a rigid movement between the installation structure of the sunshade and the vehicle body, which can easily cause damage to the vehicle body and the sunshade mechanism. External sunshades also increase the vehicle's drag and safety hazards during driving, affect the overall integrity of the vehicle body, and make it difficult to clean the exterior of the vehicle.

[0080] In other words, most common sunshades require the surrounding environment to meet their usage requirements when opened, ensuring that the poles of the extended components of the opened sunshade can vertically support the ground or the vehicle body.

[0081] In the vehicle 1000 of this embodiment, referring to the sunshade device 100 in the previous embodiment, the vehicle body 210 can be slotted according to the size of the sunshade device 100. For example, the slot can be slotted according to the size of the housing 60. The housing 60 of the sunshade device 100 is fixed to the side of the frame 220, or the fixing seat 10 is directly fixed to the side of the frame 220. The housing 60 or the fixing seat 10 can be provided with mounting holes for fixing. The number of mounting holes can be, but is not limited to, two, three, four, etc., so that the housing 60 or the fixing seat 10 is fixed to the frame 220 by bolts. A sealing ring can be provided around the mounting holes.

[0082] In the vehicle 1000 described above, the sunshade device 100 can form a fan-shaped sunshade area at a certain angle on the outer side of the vehicle body 210, and is vertically supported on the ground without the need for a pole. The vehicle body 210 can be, but is not limited to, the side wall structure of the entire vehicle or the roof 212, etc. The vehicle 1000 can be, but is not limited to, a motorhome, etc.

[0083] According to the vehicle 1000 of this utility model embodiment, the sunshade device 100 can be hidden inside the body 210 and connected to the original vehicle frame 220. The sunshade device 100 can be opened outwards through the opening 2101 when in use, and can be retracted into the body 210 when not in use.
