[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] like Figures 1 to 7As shown, an embodiment of this utility model provides a sunshade, a sunshade device, and a vehicle. The vehicle includes the sunshade device, which includes a sunshade curtain and a retractable mechanism. The retractable mechanism is used to unfold or retract the sunshade curtain. Exemplarily, the retractable mechanism uses an unrolling and retracting method to switch the sunshade curtain between unfolded and retracted states. When the sunshade curtain is needed, it is unfolded by the retractable mechanism to block the vehicle windows, providing sun protection. When the sunshade curtain is not needed, it is retracted by the retractable mechanism so that it no longer blocks the vehicle windows, meeting various user needs. It should be noted that the connection relationship between the sunshade curtain and the retractable mechanism, the installation method of the sunshade curtain and the retractable mechanism, and the working principle of the retractable mechanism controlling the unfolding and retraction of the sunshade curtain through unrolling and retracting are all existing technologies and will not be described further here.

[0043] like Figure 1 and Figure 2 As shown, the sunshade curtain includes a curtain body 1, a first fabric body 2, and a second fabric body 3. The first fabric body 2 is fixed to the edge of one end of the curtain body 1 along a first direction. The first fabric body 2 is sandwiched between the second fabric body 3 and the curtain body 1, and the first fabric body 2 is hidden between the second fabric body 3 and the curtain body 1. The second fabric body 3, the first fabric body 2, and the curtain body 1 are sewn together and fixed together. The second fabric body 3 and the curtain body 1 are welded together.

[0044] The first fabric 2 is fixed to the edge of one end of the curtain body 1 along the first direction, thereby improving the strength of the curtain body 1. The first fabric 2 is sandwiched between the second fabric 3 and the curtain body 1, and the first fabric 2 is hidden between the second fabric 3 and the curtain body 1. The second fabric 3, the first fabric 2 and the curtain body 1 are sewn and fixed, and the second fabric 3 and the curtain body 1 are welded and fixed. This not only prevents the first fabric 2 from being exposed, but also protects the first fabric 2 through the second fabric 3, and achieves a seal through welding, avoiding problems such as curling edges due to leakage of the first fabric 2. It also improves the connection stability between the first fabric 2, the second fabric 3 and the curtain body 1, which is conducive to improving the strength of the sunshade curtain, extending the service life of the sunshade curtain, and improving its aesthetics.

[0045] It should be noted that the first fabric 2 is hidden between the second fabric 3 and the curtain body 1. That is to say, the first fabric 2 does not protrude from the second fabric 3 on any side, nor does it protrude from the curtain body 1 on any side. Thus, the first fabric 2 is completely covered by the second fabric 3 and the curtain body 1, preventing the first fabric 2 from being exposed.

[0046] Furthermore, the sewing methods for the second fabric body 3, the first fabric body 2, and the curtain body 1, as well as the welding methods for the second fabric body 3, the first fabric body 2, and the curtain body 1, are all existing technologies and will not be described in detail here.

[0047] In some embodiments, the first fabric 2 is pasted and fixed to the edge of one end of the curtain body 1 along the first direction, which makes operation more convenient and helps to improve the flatness of the sunshade curtain.

[0048] In some embodiments, the first fabric 2 is a strip structure extending along a second direction, which is perpendicular to the first direction. This not only improves the strength of the curtain body 1 through the first fabric 2, but also reduces the material used and the cost, without excessively increasing the weight of the sunshade curtain.

[0049] Furthermore, the second fabric 3 is a strip structure extending along the second direction. This not only increases the strength of the curtain body 1, but also reduces the material used and the cost, without excessively increasing the weight of the sunshade curtain.

[0050] For ease of description, one end of the curtain body 1 along the first direction is referred to as the first end 11, and the first fabric 2 is attached to the edge of the first end 11 of the curtain body 1. Specifically, the strip-shaped first fabric 2 is attached to the edge of the first end 11 parallel to the edge of the first end 11 of the curtain body 1. Further, the strip-shaped second fabric 3 is fixed to the edge of the first end 11 parallel to the edge of the first end 11 of the curtain body 1.

[0051] Of course, in other embodiments, the first fabric 2 can be a strip structure extending along the second direction, or the second fabric 3 can be a strip structure extending along the second direction, which can also reduce costs without excessively increasing the weight of the sunshade.

[0052] In some embodiments, the first fabric 2 is polyester fabric, which has excellent wrinkle resistance and shape retention, which helps to improve the strength and aesthetics of the sunshade curtain.

[0053] In some embodiments, the second fabric 3 is a weft-knitted fabric. Weft-knitted fabric has the characteristics of good elasticity and strong extensibility, which can avoid problems such as loosening of sewing threads, improve the connection stability between the first fabric 2, the second fabric 3 and the curtain body 1, and enhance the aesthetics of the sunshade curtain.

[0054] In some embodiments, multiple sewing lines 4 are formed between the second fabric 3, the first fabric 2, and the curtain body 1 by sewing, which can improve the connection stability of the second fabric 3, the first fabric 2, and the curtain body 1.

[0055] In some embodiments, the plurality of sewing lines 4 include a first line (not shown in the figure), which extends along a second direction, with its two ends flush with the two ends of the curtain body 1. That is, the two ends of the first line extend to the two ends of the curtain body 1 along the second direction, thereby improving the connection stability of the second fabric 3, the first fabric 2 and the curtain body 1.

[0056] In some other embodiments, the sewing line 4 can also be set as a regular shape line such as a wavy line, a zigzag line, or a curve. The sewing line 4 can also be set as an irregular shape line, which is not limited here.

[0057] In some embodiments, a plurality of sewing lines 4 are spaced apart along a first direction, that is, a plurality of sewing lines 4 are spaced apart along the width direction of the first fabric body 2 or the second fabric body 3 of the strip structure, which can further improve the connection stability of the second fabric body 3, the first fabric body 2 and the curtain body 1.

[0058] In some other embodiments, a sewing line 4 can be formed between the second fabric 3, the first fabric 2, and the curtain body 1 by sewing, so as to facilitate sewing operations, simplify processing steps, and reduce costs.

[0059] In some embodiments, the second fabric 3 includes a first sub-fabric 31 and a second sub-fabric 32. One end of the curtain body 1 and the first fabric 2 are sandwiched between the first sub-fabric 31 and the second sub-fabric 32. In other words, the second fabric 3 has a double-layer structure. The first sub-fabric 31 and the second sub-fabric 32 are stacked to form this double-layer structure. The first sub-fabric 31 and the second sub-fabric 32 cover one end of the curtain body 1 and the first fabric 2, thereby improving the strength of the sunshade curtain and enhancing its aesthetics.

[0060] In some embodiments, the curtain body 1, the first fabric body 2, the first sub-fabric body 31, and the second sub-fabric body 32 are all sewn and fixed. Along the first direction, the end of the first sub-fabric body 31 away from the center of the curtain body 1 is connected to the end of the second sub-fabric body 32 away from the center of the curtain body 1, so as to form a cavity between the first sub-fabric body 31 and the second sub-fabric body 32. That is, one end of the first sub-fabric body 31 and one end of the second sub-fabric body 32 are connected to form a U-shaped structure. One end of the curtain body 1 and the first fabric body 2 extend into the interior of the U-shaped structure from the open end of the U-shaped structure. Thus, the edges of the curtain body 1 and the first fabric body 2 can be covered by the first sub-fabric body 31 and the second sub-fabric body 32 of the U-shaped structure, avoiding the exposure of one end of the curtain body 1 along the first direction and the first fabric body 2, thereby improving the aesthetics. At the same time, steel pipes or other supporting components can be inserted into the cavity to support the sunshade curtain, ensuring the flatness of the sunshade curtain when it is unfolded, and improving the aesthetics.

[0061] Specifically, such as Figure 3As shown, the first sub-fabric 31 is located on the side of the first fabric 2 facing away from the curtain body 1, and the second sub-fabric 32 is located on the side of the curtain body 1 facing away from the first fabric 2. The first sub-fabric 31 and the second sub-fabric 32 are integrally formed. In other words, the above-mentioned U-shaped first sub-fabric 31 and second sub-fabric 32 can be formed by folding the integral second fabric 3 in half. Of course, in other embodiments, it can also be set as follows: the first sub-fabric 31 and the second sub-fabric 32 are two independent fabric pieces, and one end of the first sub-fabric 31 and one end of the second sub-fabric 32 are connected by sewing to form a U-shaped structure.

[0062] In other embodiments, the second fabric 3 may also be configured as a single-layer strip structure, and the second fabric 3 may cover the side of the first fabric 2 facing away from the curtain body 1.

[0063] It should be noted that sunshades usually require handles for use, allowing drivers and passengers to pull them up. The handles need to be connected to supporting components such as steel pipes. Therefore, an opening 33 can be provided on the second fabric body 3, and the handle can be installed at the opening 33 to connect the handle to the supporting component.

[0064] In some embodiments, both ends of the second fabric 3 along the second direction are welded and fixed to the curtain body 1. By welding both ends of the second fabric 3, the connection stability between the second fabric 3 and the curtain body 1 can be improved, while the welding area can be reduced and the processing steps of the sunshade curtain can be simplified.

[0065] In particular, when both the first fabric body 2 and the second fabric body 3 are strip structures extending along the second direction, the two ends of the strip structure in the length direction are more likely to curl up. Through the above-mentioned arrangement, the possibility of problems such as curling up at the ends of the first fabric body 2 and the second fabric body 3 can be reduced, the service life of the sunshade curtain can be extended, and the aesthetics of the sunshade curtain can be improved.

[0066] Specifically, such as Figure 1 As shown, the second fabric 3 is welded to the curtain body 1 at both ends along the second direction, forming two welded parts 5, which makes the welding operation more convenient. Furthermore, the two welded parts 5 are respectively arranged around the outer sides of the two ends of the first fabric 2 along the second direction, thereby sealing the two ends of the first fabric 2 along the second direction through the two welded parts 5, reducing the possibility of the first fabric 2 curling up and improving the aesthetics of the sunshade curtain.

[0067] For example, the welding part 5 can be a semi-closed structure, such as a U-shape, V-shape, or C-shape, with one end open and the other closed. Further, the openings of the welding parts 5 of the semi-closed structures located at both ends of the second fabric 3 along the second direction are arranged opposite each other. The two ends of the first fabric 2 along the second direction extend into the interior of the welding part 5 of the corresponding semi-closed structure from their respective openings, so that the two semi-closed welding parts 5 respectively surround the two ends of the first fabric 2 along the second direction, resulting in a better sealing effect. Of course, the welding part 5 can also be configured as a closed structure, such as an annular structure, with the two ends of the first fabric 2 along the second direction extending into the interior of the corresponding closed welding part 5.

[0068] In some embodiments, the two ends of the second fabric 3 along the second direction do not protrude from the curtain body 1, which not only helps to prevent the two ends of the second fabric 3 along the second direction from sticking up, but also improves the aesthetics.

[0069] In some embodiments, the curtain body 1 includes a single layer of curtain fabric to meet the requirements of lightweight design and facilitate the manufacture and installation of the sunshade curtain. In other embodiments, the curtain body 1 may also include multiple layers of curtain fabric, with the multiple layers stacked together for better light-blocking effect. It should be noted that this embodiment does not limit the material of the curtain fabric.

[0070] This embodiment also provides a method for manufacturing a sunshade curtain, including the following steps:

[0071] S1. Place the curtain body 1 on the base plate 6. The base plate 6 is provided with a first positioning part corresponding to the curtain body 1. Position the curtain body 1 through the first positioning part.

[0072] For example, the first positioning part is a scribed line 61 provided on the surface of the base plate 6. The curtain body 1 can be positioned by aligning the outline of the curtain body 1 with the scribed line 61.

[0073] S2. Install the positioning block 7 on the base plate 6 and position the positioning block 7 at one end of the curtain body 1 along the first direction. The positioning block 7 is provided with a second positioning part.

[0074] For example, the positioning block 7 is provided with a positioning pin 71, and the base plate 6 is provided with a positioning hole 62. By inserting the positioning pin 71 into the positioning hole 62, the positioning block 7 can be installed on the base plate 6. Of course, the positioning pin 71 can also be provided on the base plate 6, and the positioning hole 62 can be provided on the positioning block 7.

[0075] S3, such as Figure 6 As shown, the first fabric 2 is positioned by the second positioning part and the first fabric 2 is pasted to the edge of one end of the curtain body 1 along the first direction;

[0076] It is understandable that, such as Figure 7As shown, after the first fabric 2 is pasted onto the edge of one end of the curtain body 1 along the first direction, the first fabric 2 and the curtain body 1 form an integral whole.

[0077] For example, the positioning part is the end face of one end of the positioning block 7. In other words, the first fabric 2 is positioned by the contour of one end of the positioning block 7, which not only facilitates the positioning operation, but also facilitates the manufacturing of the positioning block 7.

[0078] Before step S3, the first fabric 2 is pre-formed by punching or other methods.

[0079] S4. Place the second fabric 3 and hide the first fabric 2 between the second fabric 3 and the curtain body 1. Then sew the second fabric 3 to the first fabric 2 and the curtain body 1 after they have been glued and fixed.

[0080] S5. Weld and fix the second fabric body 3, the first fabric body 2 and the curtain body 1.

[0081] Specifically, for Figure 1 The second fabric 3, the first fabric 2, and the curtain body 1, located within the dashed frame at both ends of the second fabric 3 along the second direction, are welded together to form two welded parts 5.

[0082] The sunshade curtain manufacturing method of this embodiment uses a base plate 6 to position the curtain body 1 and a positioning block 7 to position the first fabric 2. This improves the assembly accuracy of the first fabric 2 and the curtain body 1, thereby enhancing the aesthetics of the sunshade curtain. Furthermore, after the first fabric 2 is first formed, it is glued to the curtain body 1. Then, the second fabric 3 is sewn to the glued and fixed first fabric 2 and curtain body 1. Finally, the second fabric 3, the first fabric 2, and the curtain body 1 are welded together. This not only prevents the first fabric 2 from being exposed but also provides protection for it through the second fabric 3. The welding achieves a seal, preventing issues such as edge curling caused by leakage. It also improves the connection stability between the first fabric 2, the second fabric 3, and the curtain body 1, increasing the strength of the sunshade curtain, extending its service life, and enhancing its aesthetics.

[0083] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
